This Quarterly Report modifies and supersedes documents filed prior to this Quarterly Report. The SEC allows us to "incorporate by reference" information that we file with them, which means that we can disclose important information to you by referring you directly to those documents. Information incorporated by reference is considered to be part of this Quarterly Report. In addition, information that we file with the SEC in the future will automatically update and supersede information contained in this Quarterly Report. In this Quarterly Report, "Comcast," "we," "us" and "our" refer to Comcast Corporation and its subsidiaries. You should carefully review the information contained in this Quarterly Report and in other reports or documents that we file from time to time with the SEC. In this Quarterly Report, we state our beliefs of future events and of our future financial performance. In some cases, you can identify those so-called "forward-looking statements" by words such as "may," "will," "should," "expects," "plans," "anticipates," "believes," "estimates," "predicts," "potential," or "continue" or the negative of those words and other comparable words. You should be aware that those statements are only our predictions. Actual events or results may differ materially. In evaluating those statements, you should specifically consider various factors, including the risks outlined below. Those factors may cause our actual results to differ materially from any of our forward-looking statements. Factors Affecting Future Operations We have acquired and we anticipate acquiring cable communications systems in new communities in which we do not have established relationships with the franchising authority, community leaders and cable subscribers. Further, a substantial number of new employees are being and must continue to be integrated into our business practices and operations. Our results of operations may be significantly affected by our ability to efficiently and effectively manage these changes. In addition, the cable communications industry and the provision of programming content may be affected by, among other things: o changes in laws and regulations, o changes in the competitive environment, o changes in technology, o franchise related matters, o market conditions that may adversely affect the availability of debt and equity financing for working capital, capital expenditures or other purposes, o demand for the programming content we distribute or the willingness of other video program distributors to carry our content, and o general economic conditions.

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS Basis of Presentation The condensed consolidated balance sheet as of December 31, 1999 has been condensed from the audited consolidated balance sheet as of that date. The condensed consolidated balance sheet as of September 30, 2000, the condensed consolidated statement of operations and retained earnings (accumulated deficit) for the nine and three months ended September 30, 2000 and 1999, and the condensed consolidated statement of cash flows for the nine months ended September 30, 2000 and 1999 have been prepared by Comcast Corporation (the "Company") and have not been audited by the Company's independent auditors. In the opinion of management, all adjustments necessary to present fairly the financial position, results of operations and cash flows as of September 30, 2000 and for all periods presented have been made. Certain information and note disclosures normally included in the Company's annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's December 31, 1999 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC"). The results of operations for the periods ended September 30, 2000 are not necessarily indicative of operating results for the full year. Sale of Comcast Cellular Corporation In July 1999, the Company sold its indirect wholly owned subsidiary, Comcast Cellular Corporation ("Comcast Cellular"), to SBC Communications, Inc. The results of operations of Comcast Cellular for the nine and three months ended September 30, 1999 have been presented as a discontinued operation in accordance with Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions." Reclassifications Certain reclassifications have been made to the prior years' condensed consolidated financial statements to conform to those classifications used in 2000 (see Note 2). 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SFAS No. 133, as Amended In June 1998, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement establishes the accounting and reporting standards for derivatives and hedging activity. Upon the adoption of SFAS No. 133, all derivatives are required to be recognized in the statement of financial position as either assets or liabilities and measured at fair value. In July 1999 and June 2000, the FASB issued SFAS No. 137 and SFAS No. 138 which deferred the effective date for implementation of SFAS No. 133 to fiscal years beginning after June 15, 2000 and which addressed certain issues causing implementation difficulties for entities that apply SFAS No. 133, respectively. As of September 30, 2000, the Company has entered into certain transactions which may be accounted for as derivatives upon adoption of SFAS No. 133, as amended, including indexed debt instruments, interest rate exchange agreements, equity warrant and option agreements, and equity collar agreements. The Company will adopt SFAS No. 133, as amended, on January 1, 2001. The transition adjustment upon adoption will be recorded to the Company's consolidated statement of operations as a cumulative effect of change in accounting principle, net of tax. Subsequent changes in the fair value of the Company's derivatives will be recorded either through accumulated other comprehensive income or through the Company's consolidated statement of operations based upon the Company's designation of the derivative and the Company's hedging strategy. The Company, while continuing to evaluate the impact the adoption of SFAS No. 133, as amended, will have on its financial position and results of 5

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED (Unaudited) operations, is currently unable to estimate such impact due to the uncertainty of the derivatives that will be held by the Company as of December 31, 2000 and their respective fair values at that time. SFAS No. 140 In September 2000, The FASB issued SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." SFAS No. 140 replaces SFAS No. 125 and addresses certain issues not previously addressed in SFAS No. 125. SFAS 140 is effective for transfers and servicing occurring after March 31, 2001. SFAS No. 140 is effective for disclosures about securitizations and collateral and for the recognition and reclassification of collateral for fiscal years ending after December 15, 2000. While the Company is currently evaluating the impact the adoption of SFAS No. 140 will have on its financial position and results of operations, it does not expect such impact to be material. SAB No. 101, as Amended In December 1999, the staff of the SEC issued Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements," which provides guidance in applying generally accepted accounting principles to selected revenue recognition issues. In March 2000 and June 2000, the staff of the SEC amended SAB No. 101 to delay the required implementation date of SAB No. 101 to the fourth quarter of fiscal years beginning after December 15, 1999. The Company adopted SAB No. 101, as amended, on October 1, 2000. The adoption of SAB No. 101, as amended, has not and is not expected to have a material impact on the Company's results of operations. EITF 00-10 In May, July and September 2000, the Emerging Issues Task Force (the "EITF") reached a consensus on EITF Issue No. 00-10, "Accounting for Shipping and Handling Fees and Costs." EITF No. 00-10 requires that all amounts billed to a customer in a sale transaction for shipping and handling be classified as revenue. The Company's majority-owned subsidiary, QVC, Inc. previously classified shipping and handling revenue as an offset to cost of goods sold from electronic retailing. The Company has reclassified shipping and handling revenue from cost of goods sold from electronic retailing to net sales from electronic retailing for all periods presented in the accompanying condensed consolidated statement of operations and retained earnings (accumulated deficit). Securities Lending Transactions The Company may enter into securities lending transactions pursuant to which the Company requires the borrower to provide cash collateral equal to the value of the loaned securities, as adjusted for any changes in the value of the underlying loaned securities. Loaned securities for which the Company maintains effective control are included in investments in the Company's condensed consolidated balance sheet. Earnings for Common Stockholders Per Common Share Earnings for common stockholders per common share is computed by dividing net income, after deduction of preferred stock dividends, when applicable, by the weighted average number of common shares outstanding during the period on a basic and diluted basis. 6

For the nine and three months ended September 30, 1999 such put options were not included in the computation of Diluted EPS as the options' exercise price was less than the average market price of the Company's Class A Special Common Stock during the periods. 3. SIGNIFICANT EVENTS Acquisition of Lenfest Communications, Inc. In January 2000, the Company acquired Lenfest Communications, Inc. ("Lenfest"), a cable communications company serving subscribers primarily in the Philadelphia area from AT&T Corp. ("AT&T") and the other Lenfest stockholders for approximately 121.4 million shares of the Company's Class A Special Common Stock, subject to adjustment, with a value of $6.077 billion (the "Lenfest Acquisition"). In connection with the Lenfest Acquisition, the Company assumed approximately $1.326 billion of debt (see Note 5). Consolidation of Comcast Cablevision of Garden State, L.P. Comcast Cablevision of Garden State, L.P. ("Garden State Cable") (formerly Garden State Cablevision L.P.), a cable communications company serving subscribers in New Jersey, is a partnership which was owned 50% by Lenfest and 50% by the Company. The Company had accounted for its interest in Garden State Cable under the equity method (see Note 4). As a result of the Lenfest Acquisition, the Company now owns 100% of Garden State Cable. As such, the operating results of Garden State Cable have been included in the Company's condensed 7

Acquisition of CalPERS' Interest in Jointly Owned Cable Properties In February 2000, the Company acquired the California Public Employees Retirement System's ("CalPERS") 45% interest in Comcast MHCP Holdings, L.L.C. ("Comcast MHCP"), formerly a 55% owned consolidated subsidiary of the Company which serves subscribers in Michigan, New Jersey and Florida. As a result, the Company now owns 100% of Comcast MHCP. The consideration was $750.0 million in cash. Acquisition of Jones Intercable, Inc. In April 1999, the Company acquired a controlling interest in Jones Intercable, Inc. ("Jones Intercable"), a cable communications company, for aggregate consideration of $706.3 million in cash. The acquisition was accounted for under the purchase method of accounting. As such, the operating results of Jones Intercable have been included in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit) from the acquisition date. In June 1999, the Company purchased an additional 1.0 million shares of Jones Intercable Class A Common Stock for $50.0 million in cash in a private transaction. The Company contributed its interest in Jones Intercable to Comcast Cable Communications, Inc. ("Comcast Cable"), an indirect wholly owned subsidiary of the Company. In March 2000, the Jones Intercable shareholders approved a merger agreement pursuant to which the Jones Intercable shareholders, including Comcast Cable, received 1.4 shares of the Company's Class A Special Common Stock in exchange for each share of Jones Intercable Class A Common Stock and Common Stock (the "Jones Merger") and Jones Intercable was merged with and into a wholly owned subsidiary of the Company. In connection with the closing of the Jones Merger, the Company issued approximately 58.9 million shares of its Class A Special Common Stock to the Jones Intercable shareholders, including approximately 23.3 million shares to a subsidiary of the Company and 35.6 million shares with a value of $1.727 billion to the public shareholders. As required under generally accepted accounting principles, the shares held by the subsidiary of the Company are presented as issued but not outstanding (held in treasury) in the Company's September 30, 2000 condensed consolidated balance sheet. Acquisition of Prime Communications LLC In December 1998, the Company agreed to invest in Prime Communications LLC ("Prime"), a cable communications company. Pursuant to the terms of this agreement, in December 1998 the Company acquired from Prime a $50.0 million 12.75% subordinated note due 2008 issued by Prime. In July 1999, the Company made a loan to Prime in the form of a $733.5 million 6% ten year note, convertible into 90% of the equity of Prime. Since that time, the Company made an additional $70.0 million in loans to Prime (on the same terms as the original loan). On August 1, 2000, the note, plus accrued interest of $51.7 million on the note and the loans, was converted and the owners of Prime sold their remaining 10% equity interest in Prime to the Company for $87.7 million. As a result, the Company now owns 100% of Prime and has assumed management control of Prime's operations (the "Prime Acquisition"). Upon closing, the Company assumed and repaid $532.0 million of Prime's debt with proceeds from borrowings under existing credit facilities. The acquisitions completed by the Company during the nine months ended September 30, 2000 were accounted for under the purchase method of accounting. As such, the operating results of the acquired systems have been included in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit) from the acquisition date. The Company adjusted the purchase price allocation related to the Company's acquisitions of CalPERS' interest in Comcast MHCP and of the public shareholders' interest in Jones Intercable during the second quarter of 2000. The allocation of the purchase price for the acquisitions completed during the nine months ended September 30, 2000 is preliminary pending completion of final appraisals. As the consideration given in exchange for Jones Intercable, Lenfest and the additional 50% interest in Garden State Cable was shares of the Company's Class A Special Common Stock, and in the case of Prime was primarily the conversion of 8

Unaudited Pro Forma Information The following unaudited pro forma information for the nine months ended September 30, 2000 and 1999 has been presented as if the acquisitions of Jones Intercable, Lenfest and Prime, and the consolidation of Garden State Cable each occurred on January 1, 1999. This information is based on historical results of operations, adjusted for acquisition costs, and, in the opinion of management, is not necessarily indicative of what the results would have been had the Company operated Jones Intercable, Lenfest, Garden State Cable and Prime since January 1, 1999. (Amounts in millions, except per share data) Nine Months Ended September 30, 2000 1999 ---------- ---------- Revenues................................ $5,945.9 $5,362.7 Net income.............................. $1,148.0 $769.9 Diluted EPS............................. $1.19 $0.81 AT&T Agreement As of August 11, 2000, the Company entered into a revised agreement with AT&T to exchange various cable communications systems. Under the terms of the agreement, the Company will receive cable communications systems serving approximately 770,000 subscribers. In exchange, AT&T will receive systems that the Company currently owns serving approximately 670,000 subscribers. At closing, the Company will pay AT&T an equalizing payment of approximately $12 million, reflecting the agreed upon difference in fair value of the AT&T cable communications systems and the Company's cable communications systems to be exchanged (subject to adjustment based on the actual number of net subscribers acquired and the per subscriber price of certain subscribers). The transaction is subject to customary closing conditions and regulatory approvals and is expected to close in the fourth quarter of 2000 or the first quarter of 2001. Other Income In August 2000, the Company obtained the right to sell its Excite@Home Corporation ("Excite@Home") Series A Common Stock (the "Excite@Home Stock") to AT&T and waived certain of its Excite@Home Board level and shareholder rights under a stockholders agreement. The Company also agreed to cause its existing appointee to the Excite@Home Board of Directors to resign (see Note 4). In connection with the transaction, the Company recorded a pre-tax gain of $1.045 billion, representing the estimated fair value of the investment as of the Closing Date. In 1997, the Company obtained certain wireless licenses but never deployed the spectrum in its operations. In August 2000, the Company exchanged all of the capital stock of a wholly owned subsidiary which held eighteen of those wireless licenses for approximately 3.2 million shares of AT&T common stock with a fair value of $100.0 million. In connection with the exchange, the Company recognized a pre-tax gain of $98.1 million, representing the difference between the fair value of the AT&T shares received and the Company's cost basis in the subsidiary. Such gains were recorded to other income in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit) during the nine and three months ended September 30, 2000. During the nine months ended September 30, 1999, the Company received a $1.5 billion termination fee from MediaOne Group, Inc. ("MediaOne") as a result of MediaOne's termination of its Agreement and Plan of Merger with the Company dated March 1999. The termination fee, net of transaction costs, was recorded to other income in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit). 9

The Company has reclassified its investment in the Excite@Home Stock from noncurrent investments to current investments as of September 30, 2000 (see below). On March 28, 2000 (the "Announcement Date"), Excite@Home and its principal cable partners, including the Company (the "Founding Cable Stockholders"), entered into an agreement (the "Letter Agreement") pursuant to which Excite@Home and the Founding Cable Stockholders agreed to enter into certain transactions which were completed on August 28, 2000 (the "Closing Date"). AT&T granted the Company the right to sell its Excite@Home Stock to AT&T at any time between January 1, 2001 and June 4, 2002 at a price equal to the higher of $48 per share or the average per share trading price for a 30-day trading period (as defined). The aggregate value of the Excite @Home Stock that AT&T would be required to purchase from the Company is limited to approximately $1.5 billion.

As of September 30, 2000, the Company has recorded this investment, which is included in current investments in the Company's condensed consolidated balance sheet, at its estimated fair value of $1.043 billion. The Company agreed to enter into a new non-exclusive distribution agreement with Excite@Home for the period from June 2002 through June 2006. The Company may elect to terminate its existing exclusive distribution agreement with Excite@Home (which would otherwise expire in June 2002) or the new distribution agreement at any time beginning June 2001 on at least six months notice. In addition, unearned warrants previously held by the Company were amended to eliminate any previous performance vesting conditions and the Company received additional new warrants with an exercise price of $29.54 per share to purchase two shares of Excite@Home Stock for each home passed by the Company's cable communications systems at the Announcement Date. The new warrants and the unearned previously held warrants vest in installments every six months beginning in June 2001 and will be fully vested in June 2006 provided that the Company has not elected to earlier terminate its existing or the new distribution agreement. The new warrants include customary registration rights and will expire in March 2015. The Company's right to sell its Excite@Home Stock to AT&T is not dependent upon its election to either continue or terminate its existing or the new distribution agreement.

Such gains were recorded as a reclassification from accumulated other comprehensive income to investment income. Impairment Losses During the nine months ended September 30, 2000 and 1999, the Company recorded pre-tax losses of $7.4 million and $35.5 million, respectively, on certain of its investments based on a decline in value that was considered other than temporary. Such losses are included in investment income in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit). Investment Expense (Income) Related to Call Options During the nine and three months ended September 30, 1999, the Company recorded $93.0 million and ($7.8) million, respectively, of investment expense (income) related to changes in the value of and the settlement of call options on certain of the Company's fair value method investments, all of which expired by November 1999. Equity Method The Company records its proportionate interests in the net income (loss) of certain of its equity method investees in arrears. The Company's recorded investments exceed its proportionate interests in the book value of the investees' net assets by $184.9 million as of September 30, 2000 (related to the Company's investment in The Golf Channel). Such excess is being amortized to equity in net income or loss, over a period of twenty years, which is consistent with the estimated lives of the underlying assets. The original cost of investments accounted for under the equity method totaled $367.8 million and $235.6 million as of September 30, 2000 and December 31, 1999, respectively. During the nine months ended September 30, 2000, the Company exercised a call option to purchase shares held by certain founding members and members of management and purchased shares held by other minority shareholders of The Golf Channel for aggregate consideration of $137.8 million. The Company's current ownership after these transactions is 60.3%. The Company will continue to record its investment in The Golf Channel under the equity method due to certain veto rights that are held by one of the remaining minority partners. As a result of the Lenfest Acquisition (see Note 3), the Company has consolidated the results of Garden State Cable, previously accounted for under the equity method, effective January 2000. Sales of Other Investments During the nine months ended September 30, 2000 and 1999 and during the three months ended September 30, 2000 and 1999, the Company recognized pre-tax (gains) losses to investment income of ($235.8) million, ($17.7) million, $1.6 million and ($2.8) million, respectively, on sales of certain of its other investments. 12

LONG-TERM DEBT Comcast Cable Refinancing In August 2000, the Company repaid and retired all amounts outstanding under the existing bank credit facilities of its cable communications subsidiaries, totaling approximately $2.4 billion, with the proceeds from a new senior bank credit facility and new commercial paper program. The Company's new senior bank credit facility consists of a $2.25 billion, five-year revolving credit facility and a $2.25 billion, 364-day revolving credit facility. The 364-day revolving credit facility supports the Company's new commercial paper program. The Company borrowed $1.4 billion under the five-year facility and $1.0 billion under the commercial paper program to repay and retire the subsidiaries' credit facilities. ZONES During the fourth quarter of 1999, the Company issued an aggregate of approximately 48.3 million (as adjusted for Sprint PCS' 2-for-1 stock split in February 2000) 2.0% Exchangeable Subordinated Debentures due 2029 (the "ZONES") for aggregate gross proceeds of $1.807 billion. At maturity, holders of the ZONES are entitled to receive in cash an amount equal to the higher of (a) the principal amount of the ZONES, or (b) the market value of Sprint PCS Stock. Prior to maturity, each ZONES is exchangeable at the holders option for an amount of cash equal to 95% of the market value of Sprint PCS Stock. The ZONES are being accounted for as an indexed debt instrument since the maturity value is dependent upon the fair value of Sprint PCS Stock. Therefore, the carrying value of the ZONES is marked to market each balance sheet date to reflect the fair value of the underlying Sprint PCS Stock with the change included in income related to indexed debt in the Company's condensed consolidated statement of operations and retained earnings (accumulated deficit). During the nine and three months ended September 30, 2000, the Company recorded income related to indexed debt of $666.0 million and $1.064 billion, respectively. The Company's investment in Sprint PCS is accounted for as available for sale, with changes in fair value being reflected in accumulated other comprehensive income (see Note 4). Debt Assumed In connection with the Lenfest Acquisition, the consolidation of Garden State Cable and the Prime Acquisition (see Note 3), the Company assumed aggregate debt of $2.146 billion with interest rates ranging between 6.95% and 10.5%, and maturities between 2001 and 2008.

During the nine and three months ended September 30, 2000, extraordinary items include $3.8 million of gains, net of related tax expense, recognized on the termination of related interest rate exchange agreements. Interest Rates As of September 30, 2000 and December 31, 1999, the Company's effective weighted average interest rate on its long-term debt outstanding was 6.76% and 6.55%, respectively. The Company's effective weighted average interest rate excludes the effects of the ZONES mark to market adjustments for both dates presented.

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - CONCLUDED (Unaudited) depreciation and amortization expense, operating cash flow is frequently used as one of the bases for comparing businesses in the Company's industries, although the Company's measure of operating cash flow may not be comparable to similarly titled measures of other companies. Operating cash flow is the primary basis used by the Company's management to measure the operating performance of its businesses. Operating cash flow does not purport to represent net income or net cash provided by operating activities, as those terms are defined under generally accepted accounting principles, and should not be considered as an alternative to such measurements as an indicator of the Company's performance. 17

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview We have experienced significant growth in recent years both through strategic acquisitions and growth in our existing businesses. We have historically met our cash needs for operations through our cash flows from operating activities. Cash requirements for acquisitions and capital expenditures have been provided through our financing activities and sales of investments, as well as our existing cash, cash equivalents and short-term investments. We have acquired and we anticipate acquiring cable communications systems in new communities in which we do not have established relationships with the franchising authority, community leaders and cable subscribers. Further, a substantial number of new employees are being and must continue to be integrated into our business practices and operations. Our previously announced cable system exchanges with Adelphia Communications and AT&T Corp. ("AT&T") are subject to closing conditions and regulatory approvals and are expected to close between the fourth quarter of 2000 and the second quarter of 2001. Our results of operations may be significantly affected by our ability to efficiently and effectively manage these changes. General Developments of Business See Note 3 to our condensed consolidated financial statements included in Item 1. Liquidity and Capital Resources The cable communications and the electronic retailing industry are experiencing increasing competition and rapid technological changes. Our future results of operations will be affected by our ability to react to changes in the competitive environment and by our ability to implement new technologies. However, we believe that competition and technological changes will not significantly affect our ability to obtain financing. We believe that we will be able to meet our current and long-term liquidity and capital requirements, including fixed charges, principally through our cash flows from operating activities, existing cash, cash equivalents and investments. See Note 8 to our condensed consolidated financial statements included in Item 1. Cash, Cash Equivalents and Short-term Investments We have traditionally maintained significant levels of cash, cash equivalents and short-term investments to meet our short-term liquidity requirements. Our cash equivalents and short-term investments are recorded at fair value. Cash, cash equivalents and short-term investments as of September 30, 2000 were $4.448 billion, substantially all of which is unrestricted. Investments See Note 4 to our condensed consolidated financial statements included in Item 1. A significant portion of our investments are in publicly traded companies and are reflected at fair value which fluctuates with market changes. We do not have any significant contractual funding commitments with respect to any of our investments. However, to the extent we do not fund our investees' non-binding capital calls, we are subject to dilution of our ownership interests. We continually evaluate our existing investments, as well as new investment opportunities. Financing See Notes 5 and 6 to our condensed consolidated financial statements included in Item 1. As of September 30, 2000 and December 31, 1999, our long-term debt, including current portion, was $9.924 billion and $9.225 billion, respectively. Excluding the effects of interest rate risk management instruments, 30.8% and 25.4% of our long-term debt as of September 30, 2000 and December 31, 1999, respectively, was at variable rates. The $699.2 million increase in our long-term debt, including current portion, results principally from the $1.326 billion of Lenfest Communications, Inc. ("Lenfest") debt and $534.7 million of Prime Communications LLC ("Prime") debt that we assumed, and the $286.0 million of Comcast Cablevision of Garden State, L.P. ("Garden State Cable") (formerly Garden State Cablevision L.P.) debt that we consolidated in connection with the acquisitions of Lenfest in January 2000 and Prime in August 2000 (see Notes 3 and 5 to our condensed consolidated financial statements included in Item 1), and $3.189 billion of borrowings. Such increases were offset in part by retirements and repayments of our long-term debt of $3.992 billion and the $666.0 million 18

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 non-cash, non-interest bearing reduction to the carrying value of the Company's 2.0% Exchangeable Subordinated Debentures due 2029 (the "ZONES") during the nine months ended September 30, 2000 (see Note 5 to our condensed consolidated financial statements included in Item 1). We have and may from time to time in the future, depending on certain factors including market conditions, make optional repayments on our debt obligations, which may include open market repurchases of our outstanding public notes and debentures. Equity Price Risk At maturity, holders of the ZONES are entitled to receive in cash an amount equal to the higher of (a) the principal amount of the ZONES, or (b) the market value of Sprint PCS stock. The ZONES are being accounted for as an indexed debt instrument since the maturity value is dependent upon the fair value of Sprint PCS stock. During 1999, we entered into cashless collar agreements (the "Equity Collars") covering $1.365 billion notional amount of investment securities accounted for at fair value. The Equity Collars limit our exposure to and benefits from price fluctuations in the underlying equity securities. The Equity Collars mature between 2001 and 2003. As we account for the Equity Collars as a hedge, changes in the value of the Equity Collars are substantially offset by changes in the value of the underlying investment securities which are also marked to market through accumulated other comprehensive income in our condensed consolidated balance sheet. Interest Rate Risk During the nine months ended September 30, 2000, in connection with our acquisition of Lenfest (see Note 3 to our condensed consolidated financial statements included in Item 1), we acquired interest rate exchange agreements ("Swaps") with an aggregate notional amount of $275.0 million. Swaps with an aggregate notional amount of $1.215 billion were either terminated or expired during the nine months ended September 30, 2000. As of September 30, 2000, we have Swaps with an aggregate notional amount of $784.8 million having an average pay rate of 6.88% an average receive rate of 7.56%. ----------------------- Statement of Cash Flows Cash and cash equivalents decreased $346.3 million as of September 30, 2000 from December 31, 1999. The decrease in cash and cash equivalents resulted from cash flows from operating, financing and investing activities which are explained below. Net cash provided by operating activities from continuing operations amounted to $814.7 million for the nine months ended September 30, 2000, due principally to the effects of our acquisition of Lenfest in January 2000 and Prime in August 2000 (see Note 3 to our condensed consolidated financial statements included in Item 1) and increases in our operating income before depreciation and amortization (see "Results of Operations"), offset by changes in working capital as a result of the timing of receipts and disbursements. Net cash used in financing activities from continuing operations, which includes borrowings and repayments of debt, as well as the issuances and repurchases of our equity securities, was $1.103 billion for the nine months ended September 30, 2000. During the nine months ended September 30, 2000, we borrowed $3.189 billion, consisting primarily of borrowings under subsidiary revolving lines of credit and a subsidiary commercial paper program. During the nine months ended September 30, 2000, we repaid $3.992 billion of our long-term debt, consisting primarily of $3.479 billion of repayments on certain of our revolving credit facilities and $471.0 million of aggregate repurchases of various of our senior notes and of our senior subordinated debentures. In addition, during the nine months ended September 30, 2000, we received proceeds of $23.8 million related to issuances of our common stock and the sale of put options on our common stock, we repurchased $290.3 million of our common stock, and we incurred $34.4 million of deferred financing costs. Net cash used in investing activities from continuing operations was $57.8 million for the nine months ended September 30, 2000. Net cash used in investing activities includes the effects of acquisitions, net of cash acquired, of $161.0 million, consisting of our acquisition of certain cable communications systems, investments of $353.3 million, an increase in notes receivable of $50.0 million, capital expenditures of $1.056 billion and additions to deferred charges of $334.9 million, offset by net proceeds from sales of short-term investments of $904.6 million and proceeds from sales of investments of $992.8 million. 19

Operating cash flow is a measure of a company's ability to generate cash to service its obligations, including debt service obligations, and to finance capital and other expenditures. In part due to the capital intensive nature of our businesses and the resulting significant level of non-cash depreciation expense and amortization expense, operating cash flow is frequently used as one of the bases for comparing businesses in our industries, although our measure of operating cash flow may not be comparable to similarly titled measures of other companies. Operating cash flow is the primary basis used by our management to measure the operating performance 20

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 of our businesses. Operating cash flow does not purport to represent net income or net cash provided by operating activities, as those terms are defined under generally accepted accounting principles, and should not be considered as an alternative to such measurements as an indicator of our performance. See "Statement of Cash Flows" above for a discussion of net cash provided by operating activities. Operating Results by Business Segment The following represent the operating results of our significant business segments, "Cable Communications" and "Commerce." The remaining components of our operations are not independently significant to our consolidated financial position or results of operations (see Note 9 to our condensed consolidated financial statements included in Item 1). Cable Communications The following table presents the operating results of our cable communications segment (dollars in millions): Nine Months Ended September 30, Increase 2000 1999 $ % --------- --------- --------- -------- Service income............................................... $3,056.9 $2,127.1 $929.8 43.7% Operating, selling, general and administrative expenses................................. 1,662.5 1,146.4 516.1 45.0 --------- --------- --------- -------- Operating income before depreciation and amortization (a).................................... $1,394.4 $980.7 $413.7 42.2% ========= ========= ========= ======== Three Months Ended September 30, Increase 2000 1999 $ % --------- --------- --------- -------- Service income............................................... $1,058.6 $773.5 $285.1 36.9% Operating, selling, general and administrative expenses................................. 568.5 416.7 151.8 36.4 --------- --------- --------- -------- Operating income before depreciation and amortization (a).................................... $490.1 $356.8 $133.3 37.4% ========= ========= ========= ======== - --------------- (a) See footnote (1) on page 20. Of the respective $929.8 million and $285.1 million increases in service income for the nine and three month periods from 1999 to 2000, $771.4 million and $237.9 million are due to the effects of our acquisitions of cable communications systems and $158.4 million and $47.2 million are due to growth in our historical operations. Of the respective $158.4 million and $47.2 million increases related to our historical operations, $66.5 million and $19.3 million are due principally to subscriber growth in digital cable and cable modem Internet access service, $17.5 million and $4.6 million are due to subscriber growth in analog cable service, $60.2 million and $19.3 million are related to changes in rates, $14.8 million and $4.9 million are attributable to growth in cable advertising sales and ($0.4) million and ($0.7) million are related to decreases in pay per view revenue as a result of fewer events. Of the respective $516.1 million and $151.8 million increases in operating, selling, general, and administrative expenses for the nine and three month periods from 1999 to 2000, $399.1 million and $118.9 million are due to the effects of our acquisitions of cable communications systems and $117.0 million and $32.9 million are due to growth in our historical operations. Of the $117.0 million and $32.9 million increases related to our historical operations, $48.4 million and $16.4 million are due to increases in the costs of cable programming as a result of changes in rates, subscriber growth and additional channel offerings, $33.4 million and $9.4 million are due principally to subscriber growth in cable modem Internet access service and $35.2 million and $7.1 million result from increases in labor costs and other volume related expenses. 21

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 Commerce The following presents the operating results of our commerce segment, consisting of the operations of QVC, Inc. and its subsidiaries ("QVC"), a majority owned and controlled subsidiary (dollars in millions). Nine Months Ended September 30, Increase 2000 1999 $ % --------- --------- --------- -------- Net sales from electronic retailing.......................... $2,411.9 $2,176.7 $235.2 10.8% Cost of goods sold from electronic retailing................. 1,544.4 1,398.6 145.8 10.4 Operating, selling, general and administrative expenses................................................ 449.5 401.0 48.5 12.1 --------- --------- --------- -------- Operating income before depreciation and amortization (a).................................... $418.0 $377.1 $40.9 10.8% ========= ========= ========= ======== Gross margin................................................. 36.0% 35.7% ========= ========= Three Months Ended September 30, Increase 2000 1999 $ % --------- --------- --------- -------- Net sales from electronic retailing.......................... $820.3 $751.3 $69.0 9.2% Cost of goods sold from electronic retailing................. 529.2 486.0 43.2 8.9 Operating, selling, general and administrative expenses................................................ 151.8 140.5 11.3 8.0 --------- --------- --------- -------- Operating income before depreciation and amortization (a).................................... $139.3 $124.8 $14.5 11.6% ========= ========= ========= ======== Gross margin................................................. 35.5% 35.3% ========= ========= - --------------- (a) See footnote (1) on page 20. The increase in net sales from electronic retailing of $235.2 million for the nine month period from 1999 to 2000 is due to following: an increase of 4.5%, 10.1% and 43.3% in the average number of homes receiving QVC services in the United States ("US"), United Kingdom ("UK") and Germany, respectively; an increase of 3.9% and 16.5% in net sales per home in the US and Germany (in Deutschemarks), respectively, and a 7.3% decrease in net sales per home in the UK (in British pounds); and the negative effects of fluctuations in foreign currency exchange rates during the period. The increase in net sales from electronic retailing of $69.0 million for the three month period from 1999 to 2000 is due to the following: an increase of 5.1%, 9.3% and 47.3% in the average number of homes receiving QVC services in the US, UK and Germany, respectively; an increase of 2.6% and 10.4% in net sales per home in the US and Germany (in Deutschemarks), and a 12.0% decrease in net sales per home in the UK (in British pounds), respectively; and the negative effects of fluctuations in foreign currency exchange rates during the period. The increases in cost of goods sold for the nine and three month periods from 1999 to 2000 are primarily related to the growth in net sales. The increases in gross margin are a result of a shift in sales mix. In connection with new accounting guidance issued in May, July and September 2000 (see discussion of EITF 00-10 at Note 2 to our condensed consolidated financial statements included in Item 1), QVC reclassified shipping and handling revenue from cost of goods sold from electronic retailing to net sales from electronic retailing for all periods presented. This reclassification had no effect on QVC's reported operating income before depreciation and amortization and no significant effect on growth in net sales from electronic retailing. The effect of the reclassification was to increase QVC's net sales from electronic retailing by approximately 11% and to decrease gross margin by approximately four percentage points, respectively, for all periods presented as compared to the amounts previously reported. Of the respective $48.5 million and $11.3 million increases in operating, selling, general and administrative 22

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 expenses for the nine and three month periods from 1999 to 2000, $21.7 million and $4.9 million are attributable to higher variable costs associated with the increase in sales volume. In addition, for the nine month period from 1999 to 2000, $3.1 million is attributable to certain lease termination costs incurred in the UK during the second quarter of 2000. The remaining increases are primarily attributable to higher personnel costs to support the increased sales volume in the US and Germany. ----------------------- Consolidated Analysis The effects of our recent acquisitions were to increase our revenues and expenses, resulting in increases in our operating income before depreciation and amortization. The increases in our property and equipment, deferred charges and long-term debt (see Note 7 to our condensed consolidated financial statements included in Item 1) and the corresponding increases in depreciation expense, amortization expense and interest expense for the nine and three month periods from 1999 to 2000 are primarily due to the effects of our acquisition of Lenfest in January 2000, our acquisition of a controlling interest in Jones Intercable, Inc. ("Jones Intercable") in April 1999, our acquisition of Prime in August 2000, as well as our increased levels of capital expenditures. Interest Expense The $114.2 million and $37.1 million increases in interest expense for the nine and three month periods from 1999 to 2000 are primarily due to the effects of our acquisition of Lenfest in January 2000, our acquisition of a controlling interest in Jones Intercable in April 1999 and the issuance of the ZONES in October and November 1999, offset, in part, by the effects of our repayments and retirement of debt. We anticipate that, for the foreseeable future, interest expense will be a significant cost to us and will have a significant adverse effect on our ability to realize net earnings. We believe we will continue to be able to meet our obligations through our ability both to generate operating income before depreciation and amortization and to obtain external financing. Investment Income During the nine months ended September 30, 2000 and 1999 and during the three months ended September 30, 2000 and 1999, we recognized pre-tax (gains) losses of ($827.0) million, ($67.7) million, $1.6 million and ($52.8) million, respectively, on sales of certain of our investments. During the nine months ended September 30, 2000 and 1999 and during the three months ended September 30, 2000, in connection with certain mergers of publicly traded companies held by us and accounted for as investments available for sale, we recognized pre-tax gains of $62.1 million, $187.6 million and $29.1 million, respectively, representing the difference between the fair value of the securities received by us and our basis in the securities exchanged. Such gains were recorded as reclassifications from accumulated other comprehensive income to investment income. During the nine and three months ended September 30, 1999, we recorded investment expense (income) of $93.0 million and ($7.8) million, respectively, related to changes in the value of and the settlement of call options on certain of our unrestricted equity investments, all of which expired by November 1999. During the nine months ended September 30, 2000 and 1999, we recorded pre-tax losses of $7.4 million and $35.5 million, respectively, on certain of our investments based on a decline in value that was considered other than temporary. Income Related to Indexed Debt The ZONES are being accounted for as an indexed debt instrument since the maturity value is dependent upon the fair value of Sprint PCS stock. During the nine and three months ended September 30, 2000, we recorded income related to indexed debt of $666.0 million and $1.064 billion, respectively, to reflect the decline in fair value of the underlying Sprint PCS stock. Other Income In August 2000, we obtained the right to sell our Excite@Home Series A Common Stock to AT&T and we 23

COMCAST CORPORATION AND SUBSIDIARIES FORM 10-Q QUARTER ENDED SEPTEMBER 30, 2000 waived certain of our Excite@Home Board level and shareholder rights under a stockholders agreement (see Note 4 to our condensed consolidated financial statements included in Item 1). In connection with the transaction, we recorded a pre-tax gain of $1.045 billion, representing the estimated fair value of the investment as of the closing date of the transaction. In 1997, we obtained certain wireless licenses but never deployed the spectrum in our operations. In August 2000, we exchanged all of the capital stock in a wholly owned subsidiary which held eighteen of those wireless licenses for approximately 3.2 million shares of AT&T common stock with a fair value of $100.0 million. In connection with the exchange, we recognized a pre-tax gain of $98.1 million, representing the difference between the fair value of the AT&T shares received and our cost basis in the subsidiary. Other income for the nine months ended September 30, 1999 is primarily attributable to the receipt of the $1.5 billion termination fee from MediaOne Group, Inc. ("MediaOne"), net of transaction costs, in May 1999 as a result of MediaOne's termination of its Agreement and Plan of Merger with us dated March 1999. Income Tax Expense The changes in income tax expense for the nine and three month periods from 1999 to 2000 are primarily the result of the effects of changes in our income before taxes and minority interest, and non-deductible goodwill amortization. Minority Interest The changes in minority interest for the nine and three month periods from 1999 to 2000 are attributable to the effects of our acquisition of a controlling interest in Jones Intercable in April 1999, our acquisition of the California Public Employees Retirement System's 45% interest in Comcast MHCP Holdings L.L.C. in February 2000 and to changes in the net income or loss of our other less than 100% owned consolidated subsidiaries. Extraordinary Items During the nine months ended September 30, 2000 and 1999 and during the three months ended September 30, 2000 and 1999, we incurred debt extinguishment costs and wrote off unamortized debt issue costs principally in connection with the redemption and retirement of certain indebtedness, resulting in extraordinary losses, net of related tax benefits, of $18.5 million, $44.4 million, $2.3 million and $41.4 million, respectively. During the nine and three months ended September 30, 2000, extraordinary items include $3.8 million of gains, net of related tax expense, recognized on the termination of related Swaps. We believe that our operations are not materially affected by inflation. 24

LEGAL PROCEEDINGS We are subject to legal proceedings and claims which arise in the ordinary course of our business. In the opinion of our management, the amount of ultimate liability with respect to these actions will not materially affect our financial position, results of operations or liquidity. On March 28, 2000, Excite@Home and its principal cable partners, including the Company entered into an agreement (the "Letter Agreement") which was completed on August 28, 2000. In June 2000 Cablevision Systems Corporation ("Cablevision"), a warrant holder in Excite@Home and also a party to various agreements with Excite@Home and its principal cable partners, brought an action in Delaware Chancery Court against Excite@Home and its principal cable partners seeking to enjoin the closing and alleging that the Letter Agreement breached certain contractual rights of Cablevision. In August 2000, Cablevision dismissed the claims against Excite@Home and its principal cable partners. Cablevision also consented to the completion of the Letter Agreement. 25

EXCHANGE. 2.1. Definition of Parties and Systems. 2.1.1. Basic Transaction Structure. It is understood that, pursuant to the terms and conditions of this Agreement, the relevant parties will exchange the cable television systems set forth in Schedule 2.1.1 (the "Swap"). 2.1.2. Parties to this Agreement. On the date hereof, each wholly owned or majority owned subsidiary of AT&T Corp. and each wholly owned or majority owned subsidiary of Comcast Corporation that owns any cable television system set forth on Schedule 2.1.1 is a party to this Agreement and shall be referred to herein as an "AT&T Party" or a "Comcast Party", respectively. The cable television systems listed on such Schedules that are owned by any AT&T Party shall be referred to herein as "AT&T Systems" and those owned by any Comcast Party shall be referred to herein as "Comcast Systems". Entities may, after the date -15-

hereof, be added to or deleted from the foregoing definitions, as set forth in the following provisions of this Section 2.1 and Section 2.2. Any AT&T Party that is currently or becomes the owner of an AT&T System shall be permitted prior to the Closing Time to transfer (whether directly or indirectly or by operation of law) such System to another wholly owned or majority owned entity of AT&T Corp., and, in such event, the subsequent owner of such System shall become a party to this Agreement by executing a signature page hereto and shall thereafter be treated as an AT&T Party hereunder. Similarly, any Comcast Party that is currently or becomes the owner of a Comcast System shall be permitted prior to the Closing Time to transfer (whether directly or indirectly or by operation of law) such System to another wholly owned or majority owned entity of Comcast Corporation, and in such event, the subsequent owner of such System shall become a party to this Agreement by executing a signature page hereto and shall thereafter be treated as a Comcast Party hereunder. 2.2. Exchange of Assets. Upon the terms and subject to the conditions set forth in this Agreement, at the Closing the AT&T Parties and the Comcast Parties agree to exchange simultaneously all of the right, title and interest of the AT&T Parties in, to and under the AT&T Assets for all of the right, title and interest of the Comcast Parties in, to and under the Comcast Assets, in each case free and clear of all Liens (except Permitted Liens); provided, however, that this Agreement shall not constitute an agreement to assign any Asset or any claim or right or any benefit arising thereunder or resulting therefrom without the consent of a Third Party thereto if such assignment without such consent would constitute a breach or other contravention of such Asset or in any way adversely affect the rights of the Transferee thereunder. Notwithstanding the foregoing paragraph, the Parties agree that in lieu of the Comcast Parties transferring to the AT&T Parties at Closing the Comcast Assets located in the States of Colorado, California and Georgia (the "Comcast Designated Assets") and in lieu of the AT&T Parties assuming the AT&T Assumed Obligations and Liabilities with respect to the Comcast Designated Assets (the "Comcast Designated Liabilities"), the following will apply: Immediately prior to the Closing, the Comcast Parties will transfer to one or more limited liability companies (collectively, the "Comcast Designated LLCs") all of the Comcast Designated Assets and the applicable Comcast Designated LLC will assume all of the applicable Comcast Designated Liabilities, all on terms and conditions satisfactory to the AT&T Parties. At the Closing, the Comcast Parties will transfer to the applicable AT&T Parties 100% of the limited liability company interests in each Comcast Designated LLC (collectively, "Comcast Designated LLC Interests"), free and clear of all Liens. Except as the context may otherwise require, the term "Comcast Parties" as used in this Agreement shall include the Comcast Designated LLCs. Prior to Closing, the Comcast Parties will cause the Comcast Designated LLCs to comply with the covenants in this Agreement as if they were Comcast Parties. Notwithstanding the first paragraph of this Section 2.2, the parties agree that in lieu of the AT&T Parties transferring to the Comcast Parties at Closing the AT&T Assets located in the States of Maryland and New Jersey (the "AT&T Designated Assets") and in lieu of the Comcast Parties assuming the Comcast Assumed Obligations and Liabilities with respect to the AT&T Designated Assets (the "AT&T Designated Liabilities"), the following will apply: Immediately prior to the Closing, the AT&T Parties will transfer to one or more limited liability -16-

companies (collectively, the "AT&T Designated LLCs") all of the AT&T Designated Assets and the applicable AT&T Designated LLC will assume all of the applicable AT&T Designated Liabilities, all on terms and conditions satisfactory to the Comcast Parties. At the Closing, the AT&T Parties will transfer to the applicable Comcast Parties 100% of the limited liability company interests in each AT&T Designated LLC (collectively, "AT&T Designated LLC Interests"), free and clear of all Liens. Except as the context may otherwise require, the term "AT&T Parties" as used in this Agreement shall include the AT&T Designated LLCs. Prior to Closing, the AT&T Parties will cause the AT&T Designated LLCs to comply with the covenants in this Agreement as if they were AT&T Parties. Each Parent will cause any entity that owns any Asset, but that is not a Party to this Agreement, to transfer such Asset to the appropriate Transferor prior to Closing, provided, however, that if such Asset could not be the subject of a like-kind exchange, then, in lieu of the foregoing provision, such Parent may cause such entity to transfer such Asset at Closing to a Transferee or other entity designated by the other Parent. If an entity that is not a Party owns or receives transfer of any Assets, the applicable Parent will cause such entity to comply with the obligations, covenants and terms of this Agreement in respect of such Assets as if such entity was a Party to this Agreement. Notwithstanding the first paragraph of this Section 2.2, the parties agree that the Comcast Party which would otherwise receive transfer of the AT&T DC System in the Swap may designate a limited liability company that is wholly-owned by such Comcast Party to be the Transferee of the AT&T DC System (and the AT&T Assets and Comcast Assumed Obligations and Liabilities related thereto). 2.3. Method of Exchange. Notwithstanding anything to the contrary in this Agreement, but subject to Sections 2.4 and 7.5.5, the exchange shall occur in accordance with the match-ups and in the manner set forth on Schedule 2.3 and no Party shall take any action inconsistent with the terms of such writing or Schedule. The exchange is to occur as follows: (a) the AT&T Tangible Personal Property and the Comcast Tangible Personal Property are being exchanged each for the other in "Exchange Groups" (as defined under Internal Revenue Regulations Sections 1.1031(a)-2 and 1.1031(j)-1(b)(2)); (b) the AT&T Owned Property, AT&T Leased Property and AT&T Other Real Property Interests and the Comcast Owned Property, Comcast Leased Property and Comcast Other Real Property Interests are being exchanged each for the other; and (c) the AT&T Systems Contracts, AT&T Systems Franchises, AT&T Systems Licenses and AT&T Other Intangibles and the Comcast Systems Contracts, Comcast Systems Franchises, Comcast Systems Licenses and Comcast Other Intangibles are being exchanged each for the other, in each case to the maximum extent permitted by Section 1031 of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the "Code"). 2.4. Cooperation in Structuring Exchange. Subject to Section 7.5.5(c), the Parties agree to use all reasonable efforts to structure the Swap in such a way that to the extent reasonably possible such exchange will be a Tax-free exchange of like-kind assets for all Parties under Section 1031 of the Code, including assignment of the Parties' rights under this Agreement to a "qualified intermediary" engaged by one or more of the Parties to effectuate a deferred like-kind exchange under Section 1031 of the Code. The Parties will cooperate in good -17-

faith to minimize any adverse Tax effect on the Parties in connection with such exchange, including by identifying the entities that will be party to each transfer contemplated in the Swap, so as to minimize the Taxes resulting from the Swap. Without limiting the foregoing, the Parties agree that their intent is to transfer all of the Systems, to the maximum extent possible, in transactions qualifying as Tax-free exchanges of property pursuant to Section 1031 of the Code, and the Parties will cooperate reasonably and in good faith to structure the transfers of the Systems and payment under Sections 3.1.2 and 3.1.3 in a manner that achieves this intent. 3. CONSIDERATION. Each Party hereto agrees as follows: 3.1. Calculation of Values; Payment of Additional Consideration. 3.1.1. For the purposes of this Agreement, the gross value of the Assets comprising each System (the "System Value") for each System set forth on Schedule 3.1.1-A shall equal (a) $4,591 multiplied by (b) the number of Equivalent Basic Subscribers served by such System as of the month-end prior to the Closing Date (or, in the case of any System located in Florida and any franchise area located in Long Beach Island, New Jersey, the average number of Equivalent Basic Subscribers in such System or area for the 12-month period ending on the month-end prior to the Closing Date, calculated by (x) adding together the number of Equivalent Basic Subscribers in such System at the end of each of the 13 months ending on the month-end prior to the Closing Date and (y) dividing that aggregate number by thirteen); provided that with respect to each such System the number of Equivalent Basic Subscribers in such System shall not exceed the number (the "Subscriber Cap") set forth for such System in Schedule 3.1.1-A (subject to apportionment, if applicable, pursuant to Section 7.5.5(c)). For purposes of the application of the provisions regarding the Subscriber Cap, Schedule 3.1.1-A treats the non-Overbuilt franchise areas within the MediaOne Group Detroit, Michigan System and the TCI Detroit, Michigan System as a single System. Notwithstanding the foregoing, for purposes of this Agreement, the System Value for the Comcast System located in the City of Chicago, Illinois (the "Comcast Chicago System") and the System Value for the AT&T System located in the City of Washington, D.C. (the "AT&T DC System" and together with the Comcast System, collectively, the "Appraised Systems") shall equal (a) $3,260 with respect to the AT&T DC System and $4,113 with respect to the Comcast Chicago System multiplied by (b) the number of Equivalent Basic Subscribers served by such Appraised System as of the month-end prior to the Closing Date; provided that with respect to each Appraised System the number of Equivalent Basic Subscribers in such Appraised System shall not exceed the number (the "Appraised System Subscriber Cap") set forth for such System in Schedule 3.1.1-B (subject to apportionment, if applicable, pursuant to Section 7.5.5.(c)). For purposes of this Agreement, the System Value for each of the franchise areas within the MediaOne Group, Detroit, Michigan System and the Tele-Communications, Inc. ("TCI") Detroit, Michigan System set forth on Schedule 3.1.1-C (each of which is Overbuilt) shall be as set forth on Schedule 3.1.1-C (the "Overbuilt Systems"). 3.1.2. At least ten (10) Business Days prior to the Closing, each of AT&T Corp. and Comcast Corporation shall deliver to the other a report (a "System Value Preliminary Report"), certified as to completeness and accuracy by an authorized officer of such Parent showing in reasonable detail for each System to be transferred by its Affiliates, and on a System- -18-

by-System basis, a good faith preliminary determination of the System Value, together with appropriate documents substantiating the estimates proposed in its System Value Preliminary Report. Based on such System Value Preliminary Reports, with respect to each Net Transferee Party, such Net Transferee Party shall at the Closing make a payment to the Net Transferor Party of an amount in cash (but subject to Section 3.1.3 as to the form and recipient of payment) equal to the difference between (x) the sum of the System Values for the Systems such Net Transferor is transferring to such Net Transferee Party and (y) the sum of the System Values for the Systems such Net Transferee Party is transferring to such Net Transferor Party. Any such cash payment will be made by federal wire transfer of immediately available funds pursuant to wiring instructions which wiring instructions shall be delivered by such Net Transferor Party at least five (5) Business Days prior to Closing. Such cash payments will be made first by the AT&T Parties and thereafter by the Comcast Parties. Any consideration payable by a Party pursuant to this Section 3.1.2 shall be referred to herein as "Additional Consideration". 3.1.3. Within seven (7) Business Days prior to Closing, the Parties shall determine the difference, if any, between the aggregate amount of Additional Consideration and Working Capital Adjustment Amounts that will be paid at Closing by the AT&T Parties, on the one hand, and by the Comcast Parties, on the other hand. Such difference shall be referred to herein as the "Overall Adjustment Amount" and the Parties responsible for paying such difference shall be referred to herein collectively as the "Net Payor". Notwithstanding anything to the contrary in Section 2.4, it is the intention of the Parties that the Net Payor be permitted to pay the Overall Adjustment Amount in one or more of the forms of payment listed below, at the election of the Net Payor. To effect such result, payments to be made pursuant to Sections 3.1.2 and 3.3 by a Party that is part of the Net Payor group may, to the extent of the Overall Adjustment Amount, be made by transfer and delivery of one or more of the forms of payment listed below, in lieu of cash. The Parent receiving the Overall Adjustment Amount will determine which of its Transferees will receive such alternative forms of payment. The alternative forms of payment are: (a) Series A Common Stock, par value $0.01 per share, of At Home Corporation ("@Home Common Stock") free and clear of all Liens, together with such instruments of transfer and certifications as to title and other customary and appropriate documentation and instruments as the receiving Parties shall reasonably require. For purposes of payment of the Overall Adjustment Amount, such @ Home Common Stock shall be valued at $50.02 per share (the "@Home Value"). In the event that, after June 30, 1999 and prior to the date of Closing, (i) @ Home Corporation shall issue any shares of @ Home Common Stock as a stock dividend or distribution to the holders of @ Home Common Stock, or split or combine such securities or make any cash dividend or distribution on @ Home Common Stock (other than normal quarterly cash dividends as the same may be adjusted from time to time in the ordinary course consistent with past practice), the @ Home Value in effect immediately prior to such dividend, distribution, stock split or other change shall be appropriately adjusted to reflect such dividend, distribution, stock split or other change, (ii) the @ Home Common Stock is changed into other securities, then the Net Payor shall deliver hereunder, in lieu of @ Home Common Stock, the kind and amount of securities that it received in respect of such @ Home Common Stock, (iii) additional securities (other than @ Home Common Stock) are issued or other property is distributed in respect of the @ Home Common Stock, then the Net Payor shall deliver hereunder the @ Home Common Stock and the additional securities issued or property -19-

distributed in respect thereof and (iv) any other change in the @ Home Common Stock occurs, appropriate adjustment will be made in respect of such change; and (b) the assets and liabilities of other cable television systems reasonably acceptable to the receiving parties; provided, however, that such election shall be made as promptly as practicable after the date hereof based on the Parties' best estimate of the Overall Adjustment Amount, but in no event shall such election delay the Closing by more than sixty (60) days. If the Parties agree on one or more cable television systems to be so transferred as Additional Consideration (any such system, an "Additional System"), each entity owning any such Additional System shall become a party to this Agreement (if it has not previously become a party hereto) by executing a signature page hereto. The Parent owning the Additional System will use commercially reasonable efforts to seek promptly the consent or approval of the applicable Governmental Authority to the transfer of any franchise or license of an Additional System contemplated by this Agreement. If the entity that owns an Additional System is not already a party hereto, then, effective on the date of such execution, (x) such Additional System shall be treated as an AT&T System or a Comcast System, as the case may be, under this Agreement and valued in accordance with the first sentence of Section 3.1.1 (including a Subscriber Cap based on the number of Equivalent Basic Subscribers of such Additional System as of April 30, 1999), (y) such entity shall be treated as an AT&T Party or a Comcast Party, as the case may be, under this Agreement and, as such, shall be bound as of such date by any covenants or obligations hereunder applicable thereto, and (z) the Parent shall be deemed as of such date to make the representations and warranties set forth in Section 5 or Section 6, as the case may be, as to such entity, such Additional System and the related Assets with such exceptions as are set forth in a schedule delivered on such execution date. If the entity that owns an Additional System is already a party to this Agreement, then, effective on the date the receiving Parent gives notice in writing (an "Additional System Notice") that such additional cable television system is reasonably acceptable, (x) such Additional System shall be treated as an AT&T System or a Comcast System, as the case may be, under this Agreement and valued in accordance with the first sentence of Section 3.1.1 (including a Subscriber Cap based on the number of Equivalent Basic Subscribers of such Additional System as of April 30, 1999), (y) such entity, as an AT&T Party or a Comcast Party, as the case may be, with respect to such Additional System, shall be bound as of such date by any covenants or obligations hereunder applicable thereto and (z) the Parent shall be deemed as of such date to make the representations and warranties set forth in Section 5 or Section 6, as the case may be, as to such Additional System, the related Assets and such entity with such exceptions as are set forth in a schedule delivered on the date of the Additional System Notice. For purposes of determining whether the condition set forth in Section 8.2.1 or Section 8.3.1 has been satisfied, (i) any misstatements, omissions or inaccuracies in such representations and warranties as of the Closing Date, and any scheduled exceptions thereto, shall be taken into account and (ii) the obligations, agreements and covenants of a Comcast Party or an AT&T Party, as applicable, will be deemed to have applied to such entity effective as of the date hereof. With respect to each cable television system that becomes a System pursuant to this Section 3.1.3(b), the parties shall agree in good faith as to the items to be included on Schedules 4.2 (or otherwise to be an AT&T Excluded Asset) and 4.4 (or otherwise to be a Comcast Excluded Asset), and on Schedules 5.3 and 6.3 (including those items to be marked with an asterisk (*) therein) and, except as otherwise agreed in writing, such items will be consistent with the items on those Schedules as of the date hereof. All arrangements regarding the transfer of an Additional System shall be reasonably acceptable to the Parents. -20-

3.1.4. On or after May 4, 2001, Comcast Corporation may elect to have the System Value redetermined for any franchise area within the MediaOne Group, Detroit, Michigan System or the TCI Detroit, Michigan System set forth on Schedule 3.1.1-C that is indicated on such Schedule to be Overbuilt including as of such date. Comcast Corporation shall make such election by giving notice to AT&T Corp. on or before June 2, 2001. Such notice shall list the applicable franchise areas to be redetermined and include information regarding the extent to which Comcast believes that each such franchise area is Overbuilt. In the event that Comcast Corporation timely gives such notice to AT&T Corp., within thirty (30) days thereafter, AT&T Corp. and Comcast Corporation each shall select an appraiser who shall be a nationally recognized appraiser of cable systems. The appraisers shall determine and provide in writing to AT&T Corp. and Comcast Corporation within sixty (60) days thereafter their respective appraisals of the fair market value for each such franchise area. Such reappraisal shall take into account the same factors as set forth in Section 3.1.1 as of May 4, 1999, with the sole exception being that the facts relating to the Overbuilt status thereof shall be those existing as of the date of such reappraisal. With respect to each such franchise area, (a) if the higher of the two appraisals is not more than ten percent (10%) higher than the lower appraisal, the fair market value of such franchise area shall be deemed to be the average of the values in the two appraisals, and (b) if the higher of the two appraisals is more than ten percent (10%) higher than the lower appraisal, the two appraisers shall select a third appraiser with similar qualifications (whose fees and expenses shall be shared equally by the Parents) within ten (10) days after delivery of their appraisals. The third appraiser shall determine, and provide in writing to AT&T Corp. and Comcast Corporation within sixty (60) days thereafter his or her appraisal of the fair market value for such franchise area. The fair market value of such franchise area shall be deemed to be the average of (a) the value in the third appraisal, and (b) the value that one of the first two appraisals that is closest in amount to the value in the third appraisal. The prior System Value for each of the MediaOne Group Detroit, Michigan System and the TCI Detroit, Michigan System shall be adjusted for the redetermined fair market value of any Overbuilt franchise area therein. If the redetermined System Value for such Systems is less than the System Value previously determined pursuant to Section 3.1.1, within ten (10) Business Days thereafter, AT&T Corp. shall pay by wire transfer of immediately available funds an amount equal to such difference, together with interest thereon calculated from the Closing Date through the payment date at the Prime Rate. For purposes of this Agreement, "fair market value," as determined by any appraiser pursuant to Section 3.1.4 shall mean the value for each Appraised System that would be negotiated in an arm's-length free-market tax-free transaction between a willing seller and a willing buyer, neither of whom is under undue pressure or compulsion to complete the transaction, taking into account all relevant factors, including the $4,591 per Equivalent Basic Subscriber value provided in the first sentence of Section 3.1.1 for Systems other than the Appraised Systems and the Overbuilt Systems, but excluding current assets, all long-term indebtedness classified as such in accordance with GAAP (and the portion thereof classified as current in accordance with GAAP) and other liabilities arising prior to sale. For purposes of this Agreement, "Overbuilt" means that, with respect to a franchise area within a System, as of the relevant date (a) a Person other than the owner of such System holds a franchise or other similar operating authority (whenever acquired) to build a cable system in such franchise area, and (b) either such Person has engaged in pre-construction or construction activities (whether or not -21-

construction is complete or any customers have been or are being served) or such Person has served any customers. 3.2. Working Capital Adjustment. A working capital adjustment amount shall be calculated for each System on a System-by-System basis as follows, which adjustments will be made without duplication of any amount (in each case, the "Working Capital Adjustment Amount"). The Working Capital Adjustment Amount for each System shall initially be zero and shall be increased by the amount of current assets (other than inventory) being transferred to the Transferee with respect to such System and decreased by the amount of liabilities being transferred to the Transferee with respect to such System as of the Closing Time. Current assets shall include, but are not limited to, petty cash, prepaid expenses, funds of the Transferor on deposit with Third Parties to the extent being transferred to the Transferee (other than those that are or relate to AT&T Excluded Assets or Comcast Excluded Assets or the benefit of which will not be available to the Transferee following Closing), and accounts receivable, and liabilities shall include, but are not limited to, accrued expenses (including accrued real and personal property taxes, but not other Taxes, and including copyright fees or non-programming license fees or charges), unearned income and advance payments (including subscriber prepayments and deposits for converters, encoders, cable television service and related sales) and interest, if any, required to be paid on advance payments, in each case, related to the Cable Business conducted through such System, all as determined in accordance with GAAP, to reflect the principle that all expenses and income attributable to the Cable Business for the period through and including the Closing Time are for the account of the Party owning such System, and all expenses and income attributable to the Cable Business for the period after the Closing Time are for the account of the Party receiving such System. The Party owning such System will receive no credit for (i) the portion of any account receivable resulting from cable, telephony or internet service sales that is sixty (60) days or more past due as of the Closing Date (cash received subsequent to the billing cutoff prior to the Closing Time will be applied to the active aged receivables on a pro-rata basis), (ii) the portion of any national agency account receivable resulting from advertising sales that is 120 days or more past due as of the Closing Date, (iii) any non-national agency account receivable resulting from advertising sales any portion of which is ninety (90) days or more past due as of the Closing Date, (iv) accounts receivable from customers whose accounts are inactive as of the Closing Date, or (v) any accounts receivable that have not arisen from a bona fide transaction in the ordinary course of business. For purposes of making "past due" calculations under this Section 3.2, the billing statements of a System will be deemed to be due and payable on the first day of the period during which the service is provided to which such billing statements relate. Notwithstanding the foregoing, no adjustment will be made for any items of income or expense to the extent related to AT&T Excluded Assets, Comcast Excluded Assets, AT&T Excluded Liabilities or Comcast Excluded Liabilities. In furtherance of the foregoing, the Working Capital Adjustment Amount for each System shall be decreased without duplication by the economic value of vacation time pursuant to Section 7.3.8(a) to the extent earned as of the Closing Time and permitted to be taken after the Closing Time by the System Employees employed at such System who (i) become employees of the Party receiving such System, or an Affiliate of such Party, upon the Closing or (ii) will become employees of the Party receiving such System, or an Affiliate of such Party, after being released from a leave of absence in accordance with Section 7.3.1. It is understood that the Working Capital Adjustment Amount will not reflect any intercompany receivables or payables, long-term debt (including the current portion thereof) or related accrued interest, minority interests, preferred stock, accrued -22-

programming expense, accounts payable, franchise fees or deferred taxes, as these items will not be transferred with the Systems. 3.3. Determination of Working Capital Adjustment Amount. At least ten (10) Business Days prior to the Closing, each of AT&T Corp. and Comcast Corporation shall deliver to the other a report (the "Working Capital Preliminary Report"), certified as to completeness and accuracy by an authorized officer of such Party showing in reasonable detail for each of their Systems, and on a System-by-System basis, a good faith preliminary determination of the adjustments referred to in Section 3.2 and the aggregate Working Capital Adjustment Amount, together with appropriate documents substantiating the estimates proposed in its Working Capital Preliminary Report. Based on such Working Capital Preliminary Reports, with respect to each Net Working Capital Adjustment Amount Transferee Party, such Net Working Capital Adjustment Amount Transferee Party shall at the Closing make a payment to the Net Working Capital Adjustment Amount Transferor Party of an amount in cash (but subject to Section 3.1.3 as to the form and recipient of payment) equal to the difference between (x) the sum of the Working Capital Adjustment Amount for the Systems such Net Working Capital Adjustment Amount Transferor Party is transferring to such Net Working Capital Adjustment Amount Transferee Party and (y) the sum of the Working Capital Adjustment Amount for the Systems such Net Working Capital Adjustment Amount Transferee Party is transferring to such Net Working Capital Adjustment Amount Transferor Party. Any such cash payment will be made by federal wire transfer of immediately available funds pursuant to wiring instructions which wiring instructions shall be delivered by such Net Working Capital Adjustment Amount Transferor Party at least five (5) Business Days prior to Closing. Such cash payments will be made first by the AT&T Parties and thereafter by the Comcast Parties. 3.4. Determination of Final System Values and Working Capital Adjustment Amounts. 3.4.1. Within ninety (90) days after the Closing, each of AT&T Corp. and Comcast Corporation will deliver to the other a report (the "Final Report"), certified in a manner similar to the certifications required for Preliminary Reports, showing in full detail for each System transferred by its Affiliates, and on a System-by-System basis, AT&T Corp.'s or Comcast Corporation's, as the case may be, final determination of the System Value and Working Capital Adjustment Amount for such System, which may include any adjustments that were not calculated as of the Closing Time or which are corrective of any estimated adjustments contained in the Preliminary Report, together with appropriate documents substantiating the determinations proposed in its Final Report. Each Parent will provide the other Parent with reasonable access to all records that such Parent has in its or its Affiliates possession and that are necessary for the other Parent to prepare its Final Report. 3.4.2. Within sixty (60) days after receipt of the Final Report from the other Parent, each of AT&T Corp. and Comcast Corporation will give the other written notice of such Parent's objections, if any, to the other Parent's Final Report. The Parents shall negotiate in good faith for a period of thirty (30) days, or such longer period of time as agreed by the Parents, to resolve any disputed items. If, after such thirty (30) day period (as extended, if applicable), the Parents fail so to resolve such disputed items, the Parents shall submit all then-outstanding disputed items for resolution by a national accounting firm acceptable to each Parent (or, if -23-

the Parents cannot agree, an arbitrator appointed by the American Arbitration Association) (the "Arbitrator"). As to each item in dispute, the Arbitrator's decision must be within the range of values proposed by the Parents. The Arbitrator shall render a decision within thirty (30) days after its selection, which decision shall be final and binding on the Parties hereto. Comcast Corporation and AT&T Corp. shall share equally the expenses of the Arbitrator. Once a final determination of all disputed amounts is reached, the Parents will determine whether any adjusting payments need to be made, on a Transferor/Transferee basis, to make the actual payments made at the Closing consistent with the amounts each Transferor should have transferred at the Closing based on the final determination of the System Values and the Working Capital Adjustment Amounts. Any such adjusting payments shall be paid, together with interest thereon calculated from the Closing Date through the date of payment at the Prime Rate, within three (3) Business Days after the final determination of all disputed amounts by federal wire transfers of immediately available funds pursuant to wiring instructions that shall be delivered by the Parties receiving payment at least five (5) Business Days prior to the date of such payment. 3.5. Allocation of Value. Following the Closing, the Parents agree to jointly hire an appraiser (the "Appraiser") to prepare, not later than ninety (90) days after the Closing, a written report regarding the value to be allocated to the tangible and intangible personal property included in the Assets pursuant to Internal Revenue Service regulations relating to like-kind exchanges of assets under Section 1031 of the Code. The fees of the Appraiser will be split equally between the Parents. The Parents agree that, for purposes of Sections 1031 and 1060 of the Code, each will report the transactions contemplated by this Agreement in accordance with the values determined by the Appraiser. Each Parent promptly will give the other notice of any disallowance or challenge of asset values by the Internal Revenue Service or any state or local Tax authority. 4. ASSUMED LIABILITIES AND EXCLUDED ASSETS. 4.1. AT&T Assumed Obligations and Liabilities. At the Closing and effective as of the Closing Time, each AT&T Party that is a Transferee will assume and after the Closing Time, such AT&T Party will pay, discharge and perform (as and to the extent the applicable Transferor is obligated to do so) the following (collectively, the "AT&T Assumed Obligations and Liabilities") with respect to each Comcast System transferred to such AT&T Party: (a) those obligations and liabilities accruing after the Closing Time under or with respect to the Comcast Assets assigned and transferred to such AT&T Party at the Closing, except for obligations and liabilities arising from or relating to any breach or default under any of the foregoing occurring on or prior to the Closing Time; (b) those obligations and liabilities of the Transferor for subscriber prepayments and deposits related to such Comcast System existing at the Closing Time only to the extent such amounts were used to decrease the Working Capital Adjustment Amount with respect to such System pursuant to Section 3.2; (c) other obligations and liabilities of the Transferor only to the extent that such obligations and liabilities were used to decrease the Working Capital Adjustment Amount with respect to such Comcast System pursuant to Section 3.2; and (d) all other obligations and liabilities to the extent relating to the period after the Closing Time and arising out of such AT&T Party's ownership, use or operation of the Comcast Assets (including those items listed or described on Schedule 4.4) or its operation of, or the -24-

conduct of business through, such Comcast System after the Closing (including with respect to late fees that may be charged by such AT&T Party after the Closing to subscribers of such Comcast System), except to the extent that such obligations or liabilities relate to any Comcast Excluded Asset. Except for the AT&T Assumed Obligations and Liabilities, all obligations and liabilities of the Comcast Parties or arising out of or relating to the Comcast Assets, the Comcast Systems or Comcast's Cable Business, including all long-term indebtedness classified as such in accordance with GAAP (and the portion thereof classified as current in accordance with GAAP) will remain and be the obligations and liabilities solely of the Comcast Parties ("Comcast Excluded Liabilities"). Except to the extent reflected in the Working Capital Adjustment, the Comcast Excluded Liabilities shall include any obligation, liability or claims relating to or arising pursuant to (t) any Comcast Excluded Asset, (u) any breach or default under any Comcast Asset occurring on or before the Closing Time, (v) both any Environmental Law and actions to the extent relating to the period on or prior to the Closing Time (including matters disclosed or required to be disclosed in Schedule 5.7), (w) Taxes, franchise fees, intercompany payables and any other accounts payables, in each case incurred in or attributable to periods or portions thereof ending on or prior to the Closing Time, (x) refunds of rates, charges or late fees with respect to periods through and including the Closing Time, (y) Litigation commenced, or to the extent related to the period, on or prior to the Closing Time, or (z) credit, loan or other agreements pursuant to which the Comcast Parties have created, incurred, assumed or guaranteed indebtedness for borrowed money or under which any Lien securing such indebtedness has been or may be imposed on any Comcast Asset. No Comcast Excluded Liability shall be taken into account in calculating the Working Capital Adjustment Amount. 4.2. AT&T Excluded Assets.

Each Comcast Party has all requisite power and authority to own, lease and use the Comcast Assets owned, leased or used by it and to conduct its Cable Business as it is currently being conducted by it. Each of the Comcast Parties is duly qualified to do business and is in good standing under the laws of each jurisdiction in which the ownership, leasing or use of the Comcast Assets owned, leased or used by it or the nature of its activities in connection with its Comcast Systems makes such qualification necessary, except for such matters as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. For purposes of this Agreement, "Material Adverse Effect" means, as the context requires, a material adverse effect on the business, assets, financial condition or results of operations of (a) AT&T's Cable Business, taken as a whole (excluding such effects to the extent relating to liabilities or assets to be retained by any AT&T Entity under this Agreement), or (b) Comcast's Cable Business, taken as a whole (excluding such effects to the extent relating to liabilities or assets to be retained by any Comcast Entity under this Agreement), in each case, without giving effect to the transactions contemplated by this Agreement or the announcement thereof or changes in conditions that are applicable to the cable television industry in general. 5.2. Authority and Validity. Each Comcast Entity has all requisite corporate or partnership power and authority to execute and deliver, to perform its obligations under, and to consummate the transactions contemplated by, this Agreement and the Transaction Documents to which it is a party. The execution and delivery by each Comcast Entity of, its performance under and its consummation of the transactions contemplated by, this Agreement and the Transaction Documents to which such Comcast Entity is a party have been duly and validly authorized by all action by or on behalf of such Comcast Entity. This Agreement has been, and when executed and delivered by each Comcast Entity the Transaction Documents to which such Comcast Entity is a party will be, duly and validly executed and delivered by such Comcast Entity and the valid and binding obligations of such Comcast Entity, enforceable against such Comcast Entity in accordance with their terms, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws now or hereafter in effect relating to the enforcement of creditors' rights generally or by principles governing the availability of equitable remedies. 5.3. No Conflict; Required Consents. Except as set forth on Schedule 5.3, and assuming the expiration or earlier termination of the waiting period under the HSR Act has occurred, the execution and delivery by each Comcast Entity of, its performance under and its consummation of the transactions contemplated by, this Agreement and the Transaction -29-

Documents to which such Comcast Entity is a party do not and will not: (a) conflict with or violate any provision of the organizational documents of such Comcast Entity; (b) violate any provision of any Legal Requirement; (c) require any consent, approval or authorization of, or filing of any certificate, notice, application, report or other document with, any Governmental Authority or other Person; or (d) (i) without regard to requirements of notice, lapse of time or elections of other Persons or any combination thereof, conflict with, violate, result in a breach of or constitute a default under, (ii) permit or result in the termination, suspension or modification of, (iii) result in the acceleration of (or give any Person the right to accelerate) the performance of any Comcast Entity under, or (iv) otherwise adversely affect the rights or obligations of any Comcast Entity under, any Comcast Systems Contract, Comcast Systems Franchise or Comcast Systems License, or (e) result in the creation or imposition of any Lien upon any Comcast Asset, subject to such exceptions for purposes of clauses (b), (c), (d) and (e) as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or a material adverse effect on the ability of the Comcast Entities to perform their obligations under this Agreement or the Transaction Documents. 5.4. Assets. 5.4.1. Except as described in Schedule 5.4.1, Comcast Corporation owns, directly or indirectly, all of the equity interests in the Comcast Parties. The Comcast Parties have good, marketable title to (or, in the case of Assets that are leased, valid leasehold interests in) all of the material Comcast Assets, free and clear of all Liens, except Permitted Liens. Except as described on Schedule 5.4.1 and except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, the Comcast Tangible Personal Property (which for this purpose shall include all towers on Comcast Owned Property) is in good operating condition and repair (ordinary wear and tear and routine failures excepted), and is usable and adequate for the operation of Comcast's Cable Business. 5.4.2. Subject to Sections 7.5.4(b) and 7.5.5 and except for items included in the Comcast Excluded Assets, (i) the Comcast Assets constitute in all material respects all the assets of the Comcast Entities and their Affiliates primarily held for, used in or necessary for Comcast's Cable Business and (ii) the right, title and interest therein to be transferred pursuant to this Agreement will be sufficient to permit the AT&T Parties in all material respects (a) to conduct Comcast's Cable Business as it is being conducted and in compliance with all Legal Requirements, (b) to operate the Comcast Systems as they are being operated and in compliance with all applicable Legal Requirements, and (c) to perform all the AT&T Assumed Obligations and Liabilities. 5.4.3.

Except as disclosed on Schedule 5.5.4, none of the Comcast Systems or material Comcast Assets are subject to any purchase option, right of first refusal or similar arrangement which would be triggered by the sale, transfer or other disposition of such Systems or Assets (a "Comcast System Option"). 5.5.5.

Except as set forth on Schedule 5.13, no Comcast Entity has received any notice of deficiency, assessment or audit, or proposed deficiency, assessment or audit from any taxing Governmental Authority which could affect, or result in the imposition of a Lien upon, any Comcast Assets or transferee liability or other liability upon any AT&T Entity.

The owners of the AT&T Systems have used commercially reasonable efforts to establish rates charged and a la carte packages provided to subscribers of the AT&T Systems that are currently allowable under the rules and regulations promulgated by the FCC under the 1992 Cable Act, and any authoritative interpretation thereof, to the extent such rates (on any tier) are presently subject to regulation or, as of the date such rates were implemented, were subject to regulation, by any Governmental Authority. Notwithstanding the foregoing, no AT&T Entity makes any representation or warranty that either the rates charged to subscribers or the a la carte packages provided are allowable under any rules and regulations of the FCC, or any authoritative interpretation thereof, promulgated after the date of the Closing.

Such purchase price allocations would primarily effect franchise costs, property and equipment, depreciation and amortization. Audited financial statements as of and for the year ended December 31, 1998 have been provided for the District Cablevision Limited Partnership (the Washington DC system). 6.11. Absence of Certain Changes or Events.

From May 4, 1999 to the date of this Agreement, AT&T's Cable Business has been conducted only in the usual, regular and ordinary course and no AT&T Party has taken any actions that would cause the transactions contemplated hereby to fail to qualify as a like-kind exchange under Section 1031 of the Code, except as disclosed on Schedule 6.11, except where the failure to conduct business in such manner would not have a Material Adverse Effect or a material adverse effect on the ability of the AT&T Entities to perform their obligations under this Agreement and except where such conduct out of the ordinary course was effected to carry out and comply with this Agreement. 6.12.

6.13. Tax Returns; Other Reports. The AT&T Entities have duly and timely filed in correct form all federal, state, local and foreign Tax returns and other Tax reports required to be filed, and have timely paid all Taxes that have become due and payable, whether or not so shown on any such return or report, the failure of which to be filed or paid could affect or result in the imposition of a Lien upon the AT&T Assets or create any transferee liability or other liability upon any Comcast Entity, except such amounts as are being contested diligently and in good faith and for failures to file or pay which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Except as set forth on Schedule 6.13, no AT&T Entity has received any notice of deficiency, assessment or audit, or proposed deficiency, assessment or audit from any taxing Governmental Authority which could affect, or result in the imposition of a Lien upon, any AT&T Assets or transferee liability or other liability upon any Comcast Entity.

Except to the extent that any noncompliance would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, the AT&T Entities have complied in all material respects with all applicable Legal Requirements relating to the employment of labor, including WARN, continuation coverage requirements with respect to group health plans and those relating to wages, hours, collective bargaining, unemployment insurance, workers' compensation, equal employment opportunity, age, sex, race and disability discrimination, immigration control and the payment and withholding of Taxes. 6.14.2. For purposes of this Agreement, "AT&T Plans" means each employee benefit plan (as defined in Section 3(3) of ERISA) or benefit arrangement, including each pension or welfare benefit plan, employment agreement, incentive compensation arrangement or multiemployer plan (as defined in Section 3(37) of ERISA) with respect to which the AT&T Entities or any of their ERISA Affiliates has any liability or in which any employees or agents, or any former employees or agents, of the AT&T Entities or any of their ERISA Affiliates participate. The AT&T Plans in which any AT&T System Employee (as defined in Section 6.14.3) participates are set forth on Schedule 6.14. Except to the extent that any violation would not reasonably be expected to have a Material Adverse Effect, none of the AT&T Entities, any of their ERISA Affiliates, any AT&T Plan other than a multiemployer plan (as defined in Section 3(37) of ERISA), or to the Knowledge of AT&T or any of its ERISA Affiliates, any AT&T Plan that is a multiemployer plan (as defined in Section 3(37) of ERISA) is in violation of any provision of ERISA or the Code. No material (i) "reportable event" described in Sections 4043(c)(1), (2), (3), (5), (6), (7), (10) and (13) of ERISA, (ii) non-exempt "prohibited transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code), (iii) "accumulated funding deficiency" (as defined in Section 302 of ERISA) or (iv) "withdrawal liability" (as determined under Section 4201 et seq. of ERISA) has occurred or exists and is continuing with respect to any AT&T Plan other than a multiemployer plan (as defined in Section 3(37) of ERISA), or to the Knowledge of AT&T or any of its ERISA Affiliates, any AT&T Plan that is a multiemployer plan (as defined in Section 3(37) of ERISA). After the Closing, none of the Comcast Entities or any of their ERISA Affiliates will be required, under ERISA, the Code or any collective bargaining agreement to establish, maintain or continue any -54-

AT&T Plan currently maintained by the AT&T Entities or any of their ERISA Affiliates. Since May 4, 1999, there has been no change in the benefits or level of compensation provided to AT&T System Employees that would materially increase the cost of operating the AT&T Systems. 6.14.3. Except as set forth on Schedule 6.14, there are no collective bargaining agreements applicable to any Person employed by any AT&T Entity who primarily renders services in connection with the AT&T Systems (an "AT&T System Employee") and no AT&T Entity has a duty to bargain with any labor organization with respect to any such person. Except as set forth on Schedule 6.14, there are not pending any unfair labor practice charges against any AT&T Entity, any demand for recognition or any other request or demand from a labor organization for representative status with respect to any AT&T System Employee. Except as described on Schedule 6.14, no AT&T Entity has any employment agreements, either written or oral, with any AT&T System Employee. Each of the employment agreements listed on Schedule 6.14 is terminable at will without payment or penalty and none of such agreements requires any AT&T Entity, or will require any Comcast Entity or any of its Affiliates, to employ any Person after the Closing. 6.15.

operations and such investigations and interviews do not violate any law or contract. Each Parent will cooperate on the timing of such evaluation and interviews but agree that such evaluation will begin no earlier than the date the relevant Transferor Parent delivers the list required of such Transferor Parent pursuant to Section 7.3.1. Each Transferor Parent shall use its reasonable commercial efforts to resolve (or to cause its Affiliates to resolve) at its own expense each Documented Employee Performance Case. 7.3.3.

Each Transferee Parent or such Transferee Parent's Affiliates may, but is not required to, make employment offers to the Senior Managers of the Transferor Parent. Each Parent agrees that, no later than November 10, 2000 (which date may be amended by mutual consent of the Parties), each Transferee Parent shall give the other a list of Employees (still employed by the Transferor Parent at the time) (each a "List") to whom each Transferee Parent or such Transferee Parent's Affiliates intends to offer employment prior to making such offer. Each Transferee Parent or such Transferee Parent's Affiliates may, if it wishes, and subject to applicable law, condition any offer of employment upon the System Employee being in active service on the Closing Date, System Employee's passing a pre-employment drug screening test, the completion of a satisfactory background check, and resolution of any Documented Employee Performance Case identified pursuant to Section 7.3.2, provided, however, that the determination of whether a Documented Employee Performance Case has been resolved shall be made in the sole discretion of the Transferee Parent or such Transferee Parent's Affiliates offering employment. The Transferee Parent requesting such examination shall bear the expense of such examination but the Transferor Parent shall, upon reasonable notice, cooperate in the scheduling of such examinations so long as the examinations do not unreasonably interfere with the Transferor Parent's operations. Each Transferee Parent or such Transferee Parent's Affiliates shall offer each such Employee on the applicable List employment with substantially similar responsibilities, at a geographic location within a 35-mile radius of such Employee's primary place of employment (with the exception of the Findlay, Ohio employees of the AT&T Parties, whose offer may be outside such 35-mile radius) and base compensation at least equal to the employee's base compensation as of the Closing Date, provided, however, that each Transferee Parent or such Transferee Parent's Affiliates will offer each such Employee employee benefits and total cash compensation that, in each case, are no less favorable than the employee benefits and total cash compensation, respectively, that such Transferee Parent or such Transferee Parent's Affiliates provides for its similarly situated employees with comparable experience and length of service. As of the Closing Date, neither Transferee Parent nor its Affiliates shall have any obligation to the Transferor Parent, its Affiliates or to the Transferor Parent's System Employees, with regard to any Senior Manager and Other Employees the Transferee Parent has determined, based on such evaluations prior to Closing, not to hire. Notwithstanding any of the foregoing, from the date hereof until the Closing, each Party agrees not to solicit for employment that would commence prior to the Closing Date (other than through advertisements directed at the relevant general population), without the written consent of the other, any Senior Manager. Each Parent and each of its Affiliates agrees, for a period of one year from the Closing Date, not -61-

to solicit the performance of services by any Retained Employee or Hired Employee; provided, however, that the foregoing provision will not prevent any Person from hiring any Retained Employee or Hired Employee as a result of placing general advertisements in trade journals, newspapers or similar publications which are not directed at such Retained Employees or Hired Employees. In the case of any System Employee (other than a Retained Employee) who is on Approved Leave of Absence as of the Closing Date (a "System Employee on Leave Status") whom the Transferee Parent or its Affiliates desires to hire, such Transferee Parent or its Affiliate shall employ such System Employee on Leave Status conditioned upon the Employee's return to active service within sixteen (16) weeks after the Closing Date or, if earlier, on the first Business Day following expiration of the Employee's Approved Leave of Absence. Until such date of return to active service, a System Employee on Leave Status shall not be considered a Hired Employee under this Agreement. For purposes of this Agreement, employees on "Approved Leave of Absence" means employees absent from work on the Closing Date and unable to perform their regular job duties by reason of illness or injury under approved plans or policies of the employer (other than employee's absence for less than ten (10) days due to short term illness or injury not requiring written approval by the employer) or otherwise absent from work under approved or unpaid leave policies of employer. 7.3.4. As of the Closing Date, each Transferor shall be responsible for, and shall cause to be discharged and satisfied in full, all amounts due and owing to each of its System Employees with respect to and in accordance with the terms of all compensation or benefit plans or arrangements, including, without limitation, any salaries, commissions, deferred compensation, severance, insurance, pension, profit sharing, disability payment, medical, holiday, sick pay, accrued and unused vacation in excess of the amount the applicable Transferee or its Affiliates assume pursuant to this Section 7.3, and payments under any incentive compensation or bonus agreement, in each case, which has accrued prior to the Closing Date (and, for System Employees on Leave Status, until their termination by the Transferor, or its appropriate Affiliate, or their employment by the Transferee, or its appropriate Affiliate, as set forth in Section 7.3.3). In addition, each Transferor shall retain all liabilities and obligations associated with its employees, including Systems Employees, who are not employed by the applicable Transferee or its Affiliate. 7.3.5. After the Closing Date, each Transferor shall cause each of its former employees who becomes a Hired Employee of the Transferee to be permitted to elect to receive a distribution of the full account balances of such former employee under any Code Section 401(k) plan maintained by such Transferor or its Affiliate, and the Transferee shall in each case permit to the extent allowed by Code Section 402(c) the Hired Employee to roll over any amounts so distributed in cash into a Code Section 401(k) plan maintained by the Transferee or its Affiliate. 7.3.6. Except as expressly stated to the contrary herein, all claims and obligations under, pursuant to or in connection with any welfare, medical, insurance, disability or other employee benefit plans of a Parent or any Affiliate or arising under any Legal Requirement affecting employees of such Parent or any Affiliate to the extent arising before the Closing Date will remain the responsibility of such Parent, or the appropriate Affiliate, whether or not such employees are hired by the other Parent or any of its Affiliates as of or after the Closing. Neither Parent will have or assume any obligation or liability under or in connection with any such plan of the other Parent or any Affiliate of the other Parent. For purposes of this Agreement, the -62-

following claims and liabilities shall be deemed to be incurred as follows: (i) medical, dental and/or prescription drug benefits when the treatment is provided, except with respect to such benefits provided in connection with a continuous period of hospitalization, which shall be deemed to be arising at the time of admission to the hospital; (ii) life, accidental death and dismemberment and business travel accident insurance benefits and workers' compensation benefits, upon the death, disability or accident giving rise to such benefits; and (iii) salary continuation or other short-term disability benefits, or long-term disability, upon commencement of the disability giving rise to such benefit. Each Transferor shall promptly satisfy any legal obligation with respect to continuation of group health coverage required pursuant to Section 4980B of the Code or Section 601, et seq., of ERISA. In regard to any System Employee on Leave Status, all liability for benefit coverage of such Employee, and liability for payment of benefits, shall remain that of the Transferor, or its appropriate Affiliate, until such Employee becomes an employee of the Transferee or its Affiliate after the Closing pursuant to Section 7.3.3. 7.3.7. Each Parent, or such Parent's appropriate Affiliate, will remain solely responsible for, and will indemnify and hold harmless the other Parent and its Affiliates from and against all Losses arising from or with respect to, all salaries, commissions, deferred compensation, severance, insurance, pension, profit sharing, disability payment, medical, sick pay, holiday, vacation (except for accrued vacation time and sick time included in the calculation of such Party's Working Capital Adjustment Amount), medical, holiday, continuation coverage and other compensation or benefits to which its employees may be entitled, whether or not such employees may be hired by the other Parent or any Affiliate of the other Parent, to the extent arising from their employment by such Parent or any Affiliate of such Parent on or prior to the Closing Date, the termination of their employment on or prior to the Closing Date, the consummation of the transactions contemplated hereby or pursuant to any applicable Legal Requirement or otherwise to the extent arising from their employment prior to the Closing Date (and, for System Employees on Leave Status, until their termination by the Transferor, or its appropriate Affiliate, or their employment by the Transferee, or its appropriate Affiliate, as set forth in Section 7.3.1). Any liability under WARN with regard to any employee terminated on or prior to the Closing Date, or not hired by the other Parent or its Affiliates on or after the Closing Date, shall, as a matter of contract between the parties, be the responsibility of the Parent or such Parent's Affiliates by which the employee was employed prior to the Closing Date. Each Parent and such Parent's Affiliates shall cooperate with the other Parent and such Parent's Affiliates, if requested, in the giving of WARN notices on behalf of the other Parent. 7.3.8. (a) Notwithstanding anything to the contrary herein, each Hiring Party shall: (i) upon receipt of a schedule showing the vacation and sick balances and value of such balances of each Hired Employee, which schedule shall be delivered by each Transferor to the applicable Transferee within 10 days after the Closing, credit each Hired Employee the amount of vacation and sick time permitted to be accrued by similarly situated employees of the Hiring Party in accordance with the Hiring Party's standard practices (to a maximum of four weeks for vacation and seven (7) days for sick time) accrued and unused by him or her as a System Employee of the Transferor through and including the Closing -63-

Date to the extent the Transferor's Working Capital Adjustment Amount is decreased pursuant to Section 3.2; provided, however, that, if any Hired Employee has accrued vacation and sick time in excess of the amount so credited by the Hiring Party, then the Transferor shall, and shall cause its appropriate Affiliate to, pay to such employee any amount due to such employee in respect of such excess and the Hiring Party shall not assume any liability or obligation in respect of such excess; (ii) give each Hired Employee credit for such Hired Employee's past service with the Transferor Parent and such Transferor Parent's Affiliates as of the Closing Date (including past service with any prior owner or operator of the other Parent's Systems or Cable Business) (A) for purposes of eligibility to participate in the employee welfare benefit plans in which such Hiring Party participates to the same extent as similarly situated employees of such Hiring Party and their dependents are permitted to participate; and (B) in the case of the Comcast Parties, for purposes of eligibility to participate, vesting and benefit accrual under any post-retirement medical or life insurance benefit plan which such Comcast Party maintains or in which such Comcast Party participates; (iii) give each Hired Employee credit for such Hired Employee's past service with the Transferor Parent and such Transferor Parent's Affiliates as of the Closing Date (including past service with any prior owner or operator of such other Parent's Systems or Cable Business) for purposes of eligibility for participation and vesting under the 401(k) plan, or any other retirement plan and stock plan in which such Hiring Party participates to the same extent as other similarly situated employees of such Hiring Party; (iv) give each Hired Employee credit for such Hired Employee's past service with the Transferor Parent as of the Closing Date (including past service with any prior owner or operator of such other Parent's Systems or Cable Business) for any waiting periods under the employee benefit plans, including any group health and disability plans, in which such Hiring Party participates, to the same extent as similarly situated employees of such Hiring Party, except to the extent such employees were subject to such limitations under the employee benefit plans of such Transferor Parent or any Affiliate of such Transferor Parent; and not subject any Hired Employees to any limitations on benefits for any preexisting conditions provided that the treatment is covered under such Hiring Party's or Affiliate of such Hiring Party's group health plans; and (v) credit each Hired Employee under any group health plan for any deductible amount previously met by such Hired Employee as of the Closing Date under any of the group health plans of the Transferor Parent or any of such Transferor Parent's Affiliates for the plan year in which the transfer of employment occurs. (b) Notwithstanding anything set forth in Section 7.3.8(a), the Transferee Parent and its Affiliates shall have no obligation to System Employees of the Transferor Parent -64-

or its Affiliate who are Employees on Leave Status until they become employees of the Transferee Parent and its Affiliate pursuant to Section 7.3.3. 7.3.9. Except with respect to term employees listed on Schedule 7.3.9 who become Hired Employees, if a Hiring Party discharges any Hired Employee without cause within 180 days after the Closing, then such Hiring Party shall pay severance benefits to such Hired Employee in accordance with the Transferor's severance benefit plan (the "Severance Benefits") at the Closing Date and counting the period of employment with the Transferor Parent and the Hiring Party for purposes of calculating benefits under such plan on the Closing Date; provided, however, that if a Hiring Party discharges any Hired Employee who was an "Other Employee" without cause within 60 days after Closing, then the Transferor Parent shall reimburse the Hiring Party for the Severance Benefits. Following such 180-day period, such Hired Employee shall be covered under the Hiring Party's severance benefit plan counting the period of employment with the Transferor Parent and its affiliates and the Hiring Party for purposes of calculating benefits under such plan on the Closing Date. In the case of each Transferor Parent, Schedule 7.3.9 sets forth the terms of such severance benefit plan in effect on the date hereof, and such Transferor Parent will promptly notify the Hiring Party of any changes in the terms of such plan occurring between the date hereof and the Closing Date. Each Transferor Parent agrees that between the date of this Agreement and the Closing Date, such Party will not increase the benefits provided under such severance plan, except as a result of, and consistent with, increases made by AT&T Broadband, LLC, MediaOne Group, Inc. or Comcast Cable Communications, Inc., as applicable on a company-wide basis in the benefits provided under its severance plans. For purposes of this Section 7.3.9, "cause" shall have the meaning set forth in the Hiring Party's employment policies, procedures or agreements applicable to such Hiring Party's employees who are situated similarly to the discharged Hired Employee. 7.3.10. If a Parent or its Affiliate has, or acquires, a duty to bargain with any labor organization in respect of the System Employees prior to the Closing Date, then such Parent will (i) give prompt written notice of such fact or development to the other Parent, including notice of the date and place of any negotiating sessions as they are planned or contemplated and permit the other Parent to have a representative present at all negotiating sessions with such labor organization and at all meetings preparatory thereto (including making the other Parent's representative a representative of its delegation if required by the labor organization), and (ii) not, without the other Parent's written consent, enter into any Contract with such labor organization that binds or purports to bind the other Parent or its Affiliates, including any successor clause or other clause that would have this purpose or effect. Except with respect to AT&T Corp.'s NCE Agreement, each Parent or its affiliated Transferors acknowledge and agree that the other Parent and its affiliated Transferees have not agreed to be bound, and will not be bound, without an explicit assumption of such liability or responsibility by the other Parent, by any provision of any collective bargaining agreement or similar Contract with any labor organization to which such Parent or any of such affiliated Transferors is or may become bound. 7.3.11. Notwithstanding anything set forth in this Section 7, with respect to any Hired Employee who was formerly an employee of MediaOne Group ("M1 Hired Employee"), the Comcast Entity who hires such M1 Hired Employee shall additionally: (a) not, prior to January 1, 2002, increase the employee contribution level, under employee welfare benefit plans, -65-

above the level required while such M1 Hired Employee was a MediaOne employee and (b) if such Comcast Entity discharges any M1 Hired Employee without cause before June 15, 2002, then such Comcast Entity shall pay severance benefits to such M1 Hired Employee in accordance with the Severance Benefit in effect for such M1 Hired Employee set forth in Schedule 7.3.11 and counting the period of employment with the other Parent and its affiliates and the hiring Comcast Entity for purposes of calculating benefits under such plan on the Closing Date; provided, however, that if a Comcast Entity discharges any M1 Hired Employee who was an "Other Employee" without cause within 60 days of Closing, then AT&T Corp. shall reimburse Comcast Corporation, for the Severance Benefits paid to such M1 Hired Employee. 7.3.12. Nothing in this Section 7.3 or elsewhere in this Agreement shall be deemed to make any employee of either Parent or its Affiliates a third party beneficiary of this Agreement. 7.3.13. The parties agree to cooperate with each other and to exchange all information required to implement the provisions of this Section 7.3. 7.4. Leased Vehicles; Other Capital Leases. Each Transferor will pay the remaining balances on any leases for vehicles or capital leases that would be included in its Assets but for the effect of this Section 7.4, and will deliver title to such vehicles and other Tangible Personal Property included among its Assets, free and clear of all Liens (other than Permitted Liens), to the receiving Transferee at the Closing. 7.5. Required Consents; Franchise Renewal. 7.5.1. Each Transferor will use its commercially reasonable efforts to (i) obtain in writing, as promptly as possible and at its expense, all of the Required Consents, other than consents in connection with multiple dwelling unit agreements, required to be obtained by such Transferor in connection with the transactions contemplated by this Agreement, and deliver to the other Parent copies of such Required Consents and such other consents, authorizations or approvals promptly after they are obtained by such Transferor, and (ii) give any required written notice in connection with the transactions; provided that each Transferor will afford the other Parent the opportunity to review, and comment on the form of letter or application proposed to request the Required Consent or form of written notice prior to delivery to the Person whose consent is sought or to whom such notification is required. All documents delivered or filed with any Governmental Authority or any Person by or on behalf of such Transferor pursuant to this Section 7.5.1, when so delivered or filed, will be correct, current and complete in all material respects. Each Party will cooperate with the other Parties to obtain all Required Consents and no Party shall intentionally take any action or steps that would prejudice or jeopardize the obtaining of any Required Consent. 7.5.2. No Transferor will accept or agree or accede to any modifications or amendments to, or the imposition of any condition to the transfer of, any of the System Franchises, System Licenses or System Contracts of such Transferor's Cable Business that are not reasonably acceptable to the other Parent. Notwithstanding the foregoing, each Party will cooperate with the other Parties and use commercially reasonable efforts to complete, execute and deliver, or cause to be completed, executed and delivered, to the appropriate Governmental -66-

Authority, a FCC Form 394 to the extent not previously filed with respect to each System Franchise included among the Assets within thirty (30) days after the date of this Agreement. Without the prior consent of the other Parent, no Transferor shall agree with any Governmental Authority to extend or to toll the time limits applicable to such Governmental Authority's consideration of any FCC Form 394 filed with such Governmental Authority. 7.5.3. Notwithstanding the provisions of Sections 7.5.1 and 7.5.2, no Transferor will have any further obligation to obtain Required Consents: (a) with respect to license agreements relating to pole attachments where the licensing authority will not consent to an assignment of such license agreement but requires that the Transferee enter into a new agreement with such licensing authority on terms that are not materially less favorable in the aggregate to the Transferee, in which case the Transferee shall use its commercially reasonable efforts to enter into such agreement prior to the Closing or as soon as practicable thereafter, and the Transferor will cooperate with and assist the Transferee in obtaining such agreements; (b) for any business radio license or any private operational fixed service ("POFS") microwave license which would reasonably be expected to be obtained within 120 days after the Closing and so long as a conditional temporary authorization (for a business radio license) or a special temporary authorization (for a POFS license) is obtained by the Transferee under FCC rules with respect thereto; (c) with respect to Contracts evidencing Leased Property, if, with the consent of the other Parent, the Transferor obtains and makes operational prior to the Closing substitute Leased Property that is, and that is leased on terms that are, reasonably satisfactory to the other Parent; (d) with respect to Contracts evidencing leased Tangible Personal Property that is material to its Cable Business, if, with the consent of the other Parent, such Transferor obtains and makes operational prior to the Closing substitute Tangible Personal Property that is reasonably satisfactory to the other Parent. 7.5.4. (a) Upon the written request of the Transferee, if and to the extent that any Required Consents (except Required Consents for the transfer of Systems Franchises, which shall be governed by Section 7.5.5) have not been obtained on or prior to the Closing (whether or not any Party shall have waived satisfaction of the condition to the Closing set forth in Section 8.2.5 or Section 8.3.5), subsequent to the Closing, each Transferor will continue to use commercially reasonable efforts to obtain in writing, as promptly as possible, such Required Consents required to be obtained by such Transferor and will deliver copies of the same, reasonably satisfactory in form and substance, to the other Parent. The obligations set forth in this Section 7.5.4 will survive the Closing. (b) If any Required Consent (except Required Consents for the transfer of Systems Franchises, which shall be governed by Section 7.5.5) shall not have been obtained prior to Closing, the affected Transferor and Transferee will cooperate in a mutually agreeable arrangement under which, to the extent practicable and permitted by such agreement and applicable law, such Transferee will obtain the benefits and be responsible for the obligations in accordance with this Agreement in respect of such Asset or any claim or right or any benefit arising thereunder the assignment of which without the consent of the Third Party thereto would constitute a breach or other contravention of such Asset or in any way adversely affect the rights of such Transferee thereunder, including sub-contracting, sub-licensing, or sub-leasing to such Transferee, or under which such Transferor will enforce for the benefit of such Transferee, with such Transferee assuming such Transferor's obligations, any and all rights of such Transferor -67-

against the Third Party in question. Such Transferor will promptly pay to such Transferee, when received, all monies received by such Transferor in respect of any such Asset or any claim or right or any benefit arising thereunder and such Transferee shall promptly pay or perform any obligations in respect of any such Asset. 7.5.5. If the conditions set forth in Sections 8.2.5(a) and 8.3.5(a) are satisfied and there remain Service Areas of the AT&T Systems or the Comcast Systems that are not, as of the Closing Time, Transferable Service Areas, then the following shall occur: (a) With respect to each AT&T Systems Franchise for which a Required Consent has not been obtained as of the Closing Time (including any Assets that are primarily held for, used in, or necessary for AT&T's Cable Business in the relevant franchise area and related liabilities, an "AT&T Retained Franchise"), the Parties will negotiate in good faith to reach agreement on a Comcast Systems Franchise (including any Comcast Assets that are primarily held for, used in, or necessary for Comcast's Cable Business in the franchise area and related liabilities, a "Comcast Matching Franchise") that is, to the greatest extent possible, like kind to such AT&T Retained Franchise for purposes of Section 1031 of the Code and the applicable exchange, and such Comcast Matching Franchise shall be retained by the applicable Comcast Party, while the corresponding AT&T Retained Franchise is retained by the applicable AT&T Party. A Comcast Matching Franchise may also be a Comcast Retained Franchise. For purposes of this Section 7.5.5, a "Retained Franchise" means either an AT&T Retained Franchise or a Comcast Retained Franchise or both, as the context requires, and a "Matching Franchise" means either an AT&T Matching Franchise or a Comcast Matching Franchise or both, as the context requires. (b) With respect to each Comcast Systems Franchise for which a Required Consent has not been obtained as of the Closing Time (including any Assets that are primarily held for, used in, or necessary for Comcast's Cable Business in the relevant franchise area and related liabilities, a "Comcast Retained Franchise"), the Parties will negotiate in good faith to reach agreement on an AT&T Systems Franchise (including any AT&T Assets that are primarily held for, used in or necessary for AT&T's Cable Business in the franchise area and related liabilities, an "AT&T Matching Franchise") that is, to the greatest extent possible, like kind to such Comcast Retained Franchise for purposes of Section 1031 of the Code and the applicable exchange, and such AT&T Matching Franchise shall be retained by the applicable AT&T Party, while the corresponding Comcast Retained Franchise is retained by the applicable Comcast Party. An AT&T Matching Franchise may also be an AT&T Retained Franchise. (c) The Parties shall cooperate, negotiate in good faith and enter into mutually acceptable arrangements on commercially reasonable terms to address all issues and concerns regarding each Retained Franchise and Matching Franchise and related matters, including (i) the terms on which the appropriate Party, from and after the Closing Date, would provide to the Party that retains such Retained Franchise and Matching Franchise such signal delivery, management and other support services as may be necessary or appropriate due to the existence of such Retained Franchise and Matching Franchise, (ii) the terms regarding the transfer of such Retained Franchise and Matching Franchise to the appropriate Party after the receipt of all Required Consents applicable to such Retained Franchise and Matching Franchise, (iii) determination and payment of the Additional Consideration and Working Capital -68-

Adjustment Amount with respect to such Retained Franchise and Matching Franchise at the time of such transfer (rather than at Closing) consistent with provisions of this Agreement, (iv) with respect to the period prior to such transfer or in the event transfer is not made because Required Consents are not obtained, the terms regarding other arrangements to achieve substantially the same division of economic benefits and burdens as between the parties as would have resulted if the transfer had taken place at Closing, (v) the possible revision of Schedule 2.3 to reduce the taxes payable as a result of the transactions hereunder and (vi) apportionment of the Subscriber Cap among the franchise areas in any System that contains a Retained Franchise or a Matching Franchise based on the number of Equivalent Basic Subscribers in each such franchise area as set forth on Schedule 5.15.1(b) or Schedule 6.15.1(b), as the case may be, provided that any such matter is mutually acceptable to both Parents. 7.5.6. No Party shall be required to make any payment (other than customary filing and similar fees) to a Person from whom consent is sought in order to obtain such consent and no Party shall be obligated to reimburse any other Party for any payment so made. 7.6. Title Commitments and Surveys. Each Transferee will have the option to obtain, at its own expense, (i) commitments of title insurance ("Title Commitments") issued by a nationally recognized title insurance company selected by such Transferee (the "Title Company") and containing policy limits and other terms reasonably acceptable to such Transferee, and photocopies of all recorded items described as exceptions therein committing to insure fee or leasehold title in such Transferee to each parcel of Owned Property or Leased Property to be transferred to such Transferee hereunder, by American Land Title Association ("ALTA") (1992) owner's or lessee's policies of title insurance, and (ii) current ALTA as-built surveys of each such parcel as is necessary to obtain the title insurance to be issued pursuant to the Title Commitments with the standard printed exceptions relating to survey matters deleted (the "Surveys"), certified to the Transferee and the Title Company issuing a Title Commitment. If a Transferee notifies a Transferor within twenty (20) days after the date of this Agreement or, if later, of its receipt of both the Title Commitments and the Surveys of any Lien (other than a Permitted Lien) or other matter affecting title to such Owned Property or Leased Property which prevents or materially interferes with (or presents a material risk of preventing or interfering with) the use of any such parcel for the purposes for which it is currently used or operated (each a "Title Defect"), such Transferor will, at its own expense, exercise commercially reasonable efforts to remove or, with the consent of the Transferee, cause the Title Company to commit to insure over, each such Title Defect prior to the Closing. 7.7. HSR Act Notification. If any event (including the passage of time) occurs which subjects the transactions contemplated by this Agreement to any further requirements under the HSR Act, then as promptly as practicable, the Comcast Parties and the AT&T Parties will each complete and file, or cause to be completed and filed, at its own cost and expense, any notification and report required to be filed under the HSR Act with respect to the transactions contemplated by this Agreement, and each such filing shall request early termination of the waiting period imposed by the HSR Act. The Parties shall use their respective commercially reasonable efforts to respond, as promptly as reasonably practicable, to any inquiries received from the Federal Trade Commission (the "FTC") and the Antitrust Division of the Department of Justice (the "Antitrust Division") for additional information or documentation, and to respond, as promptly as reasonably practicable, to all inquiries and requests received from any -69-

other Governmental Authority in connection with antitrust matters. The Parties shall use their respective commercially reasonable efforts to overcome any objections which may be raised by the FTC, the Antitrust Division or any other Governmental Authority having jurisdiction over antitrust matters. Each Party shall (i) promptly notify the other Party of any written communication to that Party from the FTC, the Antitrust Division, any State Attorney General or any other Governmental Authority and, subject to applicable law, permit the other Party to review in advance any proposed written communication to any of the foregoing; (ii) not agree to participate in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning this Agreement or the transactions contemplated hereby unless it consults with the other Party in advance and, to the extent permitted by such Governmental Authority, gives the other Party the opportunity to attend and participate thereat; and (iii) furnish the other Party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their Affiliates and their respective representatives on the one hand, and any Government Authority or members or their respective staffs on the other hand, with respect to this Agreement and the transactions contemplated hereby. Notwithstanding the foregoing, no Party shall be required to make any significant change in the operations or activities of the business (or any material assets employed therein) of such Party or any of its Affiliates or the Cable Business to be acquired by such Party if a Party determines in good faith that such change would be materially adverse to the operations or activities of the business (or any material assets employed therein) of such Party or any of its Affiliates having significant assets, net worth or revenue. 7.8. Sales and Transfer Taxes. Comcast and AT&T shall each, respectively, pay one-half of (i) all Transfer Taxes arising from or payable by reason of the transfer of any of the AT&T Assets or any of the Comcast Assets and (ii) all Transfer Taxes or assessments, and any transfer fees and similar assessments for or under Systems Franchises, Systems Licenses and Systems Contracts, arising from or payable by reason of the conveyance of the AT&T Assets or the Comcast Assets. The Parties agree to use all reasonable efforts, subject to Section 2.4, to structure the Swap in such a manner as to minimize the Transfer Taxes payable in connection therewith. The Parties agree to use all reasonable efforts to reduce the amount of material Transfer Taxes payable by each Party. Notwithstanding the foregoing, all Transfer Taxes or assessments, and transfer fees and similar assessments arising from or payable by reason of any internal restructuring implemented by any Party prior to the Closing will be borne by such Party. 7.9. Programming. Each Transferor will execute and deliver letters substantially in the form attached as Exhibit 7.9 as may be reasonably requested by Transferee to Persons that are parties to such Transferor's programming agreements. 7.10. Retention of Books and Records. Following the Closing, each Transferor shall give access to the receiving Transferee, its Parent, counsel, accountants and other authorized representatives during normal business hours to such Transferor's materials, books, records and documents which relate to the operations of such Transferor's Cable Business prior to the Closing Time as may be reasonably necessary in connection with any legitimate purpose (including the preparation of tax reports and returns and the preparation of financial statements). Such access will be subject to the generally applicable document retention policies of such Transferor (provided that each Transferor will use commercially reasonable efforts not to destroy any such records without first notifying the Transferee and giving the Transferee the opportunity -70-

to make copies), shall be subject to reasonable advance written notice, will be conducted in a manner that is not disruptive of such Transferor's business and will be subject to any other reasonable limitations imposed by such Transferor. The Transferee shall have the right to make copies of such materials at its own expense. 7.11. Use of Name and Logo. For a period of 180 days after the Closing, each Transferee will be granted a non-exclusive, non-transferable license to use the trademarks, trade names, service marks, service names, logos and similar proprietary rights of the applicable Transferor to the extent incorporated in or on the Assets transferred to it at the Closing on a royalty-free basis, provided that each Transferee will exercise commercially reasonable efforts to remove all such names, marks, logos and similar proprietary rights of such Transferor (except to the extent otherwise permitted by such Transferor) from such Assets as soon as reasonably practicable, and in any event within 180 days, following the Closing. Notwithstanding the foregoing, nothing in this Section 7.11 will require any Transferee to remove or discontinue using any such name or mark that is affixed to converters or other items already installed in or to be used in customer homes or properties and transferred to such Transferee as of the Closing, or as are already installed and used in a similar fashion as of the Closing, making such removal or discontinuation impracticable. 7.12. Transitional Billing Services. Each Transferor will provide to the Transferee of its Systems, upon written request delivered a reasonable amount of time in advance, access to and the right to use its billing system computers, software and related fixed assets in connection with the Systems transferred for a period of up to 180 days following the Closing to allow for conversion of existing billing arrangements, including billing and related arrangements (such as refunds) regarding internet access and telephony services being provided to customers of a System on the Closing Date ("Transitional Billing Services"). Each Transferee will notify such Transferor at least thirty (30) days prior to the Closing as to whether it desires Transitional Billing Services from such Transferor. All Transitional Billing Services, if any, that are requested by a Transferee will be provided on terms and conditions reasonably satisfactory to the Transferor and the Transferee; provided, however, that the amount to be paid by the Transferee receiving Transitional Billing Services will not exceed the cost to such Transferor of providing such Transitional Billing Services.

Each Party will cooperate with and assist the other Parties by providing, upon reasonable request, all information in its possession (and not previously made available to the requesting Party) that the requesting Party may reasonably require to justify rates, charges, late fees and similar payments in response to any inquiry, order or requirements of any Governmental Agency. 7.17.4. If, following the Closing any System is required pursuant to any Legal Requirement, settlement or otherwise to refund to subscribers any payments, in whole or in part, made by such subscribers prior to the Closing, including fees for cable television service, equipment charges, late fees and similar payments, then, at the election of the Transferee of such System: (i) the Transferor must fulfill such refund obligation through a one-time cash payment to subscribers, in which case the Transferor shall provide funds for such payment to the Transferee, the Transferee shall cooperate with the Transferor or implement and administer such refund payment through the Transferee's billing system, and the Transferor shall reimburse the -73-

Transferee for all reasonable expenses incurred by the Transferee in connection therewith; or (ii) the Transferee may fulfill such refund obligation through a cash payment, credit or in-kind or other form of consideration, at its discretion and subject to any required approval by a Governmental Authority, and the Transferor shall reimburse the Transferee in the amount of any payment or in the amount of the cost to the Transferee of any credit or in-kind or other form of consideration and all reasonable expenses incurred by the Transferee in connection therewith.

If a Transferee is permitted following the Closing to pass through to subscribers of Systems acquired by it at Closing, the amount of any "franchise fees on franchise fees" paid by a Transferor to the appropriate local franchising authority with respect to the period prior to the Closing, the Transferee agrees that it will collect, for the benefit of the Transferor, such amounts specified no later than the Six-Month Date as paid by the Transferor and, except as specified below, will promptly remit such amounts to the Transferor; provided, however, that if a Transferee is provided by counsel with an opinion that the pass through to subscribers of such fees under the rules and regulations of the FCC and the Communications Act (either with respect to the cable industry as a whole or the particular Systems in question) is subject to administrative or judicial review, then the Transferee shall not remit the fees to the Transferor but shall hold such fees until the final resolution of such administrative or judicial proceedings. After such final resolution, the Transferee will remit to Transferor as appropriate, such fees. The Transferor agrees to provide the Transferee with such documentation as necessary to demonstrate its payment of the "franchise fees on franchise fees" and to enable the Transferee to collect the pass through amounts from subscribers. No amount collectible for the benefit of a Transferor under this Section 7.17.5 will be taken into account in determining the Working Capital Adjustment Amount. 7.18.

Upon receipt by any Person of notice of any claim, action, suit or proceeding by any Third Party (collectively, an "Action"), which Action is subject to indemnification under this Agreement, such Person (the "Indemnified Party") will give reasonable written notice to the Party from whom indemnification is claimed (the "Indemnifying Party"); provided that the failure of any Indemnified Party to so deliver notice shall not relieve the Indemnifying Party of its obligations under this Article 11, except to the extent the Indemnifying Party is prejudiced by such failure. The Indemnified Party will be entitled, at the sole expense and liability of the Indemnifying Party, to exercise full control of the defense, compromise or settlement of any such Action unless the Indemnifying Party, within a reasonable time after the giving of such notice by the Indemnified Party, (i) notifies the Indemnified Party in writing of the Indemnifying Party's intention to assume such defense, (ii) retains legal counsel reasonably satisfactory to the Indemnified Party to conduct the defense of such Action and (iii) admits in writing to the Indemnified Party the Indemnifying Party's liability to the Indemnified Party for such Action to the extent provided in this Agreement. The other Party will cooperate with the Party assuming the defense, compromise or settlement of any such Action in accordance with this Agreement in any manner that such party reasonably may request. The Party controlling the defense, compromise or settlement of an Action shall act in good faith with respect thereto. If the Indemnifying Party so assumes the defense of any such Action, the Indemnified Party will have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement of the Action (in which case the Indemnifying Party shall cooperate in providing information to the Indemnified Party about the Action), but the fees and expenses of such counsel will be at the expense of the Indemnified Party unless (i) the Indemnifying Party has agreed to pay such fees and expenses, (ii) any relief other than the payment of money damages is sought against the Indemnified Party or (iii) the Indemnified Party has been advised by independent counsel that there may be one or more defenses available to it which are different from or additional to those available to the Indemnifying Party, and in any such case that portion of the fees and expenses of such separate counsel that are reasonably related to matters covered by the indemnity provided in this Article 11 will be paid by the Indemnifying Party, provided that the Indemnifying Party shall not be obligated to pay the expenses of more than one separate counsel in each jurisdiction for each Indemnified Party so entitled to separate counsel. No Indemnified Party will settle or compromise any such Action for which it is entitled to indemnification under this Agreement -83-

without the prior written consent of the Indemnifying Party. No Indemnifying Party will settle or compromise any such Action in which any relief other than the payment of money damages is sought against any Indemnified Party, unless the Indemnified Party consents in writing to such compromise or settlement. Notwithstanding the foregoing in this Section 11.3, if an Action includes or could reasonably be expected to include both a claim for Taxes (other than income Taxes) that are the responsibility of any AT&T Entity hereunder, on the one hand, and a claim for Taxes (other than income Taxes) that are the responsibility of any Comcast Entity hereunder, on the other hand, then Comcast Corporation (if the claim for Taxes that are the responsibility and liability of the Comcast Entities exceeds the claim for Taxes that are the responsibility and liability of the AT&T Entities) or otherwise AT&T Corp. (as the case may be, the "Controlling Party") shall be entitled to control the defense of such Action (such Action, a "Tax Action"). In such case, the other Party (the "Non-Controlling Party") shall be entitled to participate fully (at the Non-Controlling Party's sole expense) in the conduct of such Tax Action and the Controlling Party shall not settle such Tax Action without the consent of the Non-Controlling Party (which consent shall not be unreasonably withheld). The costs and expenses of conducting the defense of such Tax claim shall be reasonably apportioned based on the relative amounts of the claim for Taxes that are the responsibility of any AT&T Entity hereunder and Taxes that are the responsibility of any Comcast Entity hereunder based on the relative amounts of such claims. For purposes of Sections 4.1(w) and 4.3(w) and this Article 11, all real property taxes, personal property taxes and similar ad valorem obligations in respect of any System or Asset for any taxable period that includes but does not end on the Closing Date shall be apportioned between the Transferor and the Transferee based on the number of days of such taxable period on or prior to the Closing Date and the number thereof after the Closing Date. For purposes of this Agreement, an Escheat Payment shall be attributable to a period (or portion thereof) ending on or prior to the Closing Date if the relevant abandoned or unclaimed property was or should have been accrued as an unclaimed property liability in the normal course of the Indemnifying Party's operations in such pre-Closing period. For purposes of the foregoing, the Parties agree that unclaimed property liabilities should in all events be accrued in the ordinary course within one year after the date the relevant abandoned or unclaimed property is first proffered. 11.4. Limitations on Indemnification. (a) The AT&T Entities will have no liability under Section 11.1(a) unless the amount of Losses otherwise subject to their indemnification obligations thereunder exceeds $17,500,000 (the "AT&T Minimum Damage Requirement"), in which case the AT&T Entities shall be liable only for such excess provided that the AT&T Minimum Damage Requirement will not apply to any Losses resulting from or arising out of breaches of the representations and warranties in Sections 6.1, 6.2, 6.3(a), 6.3(b) or 6.17. The maximum liability of the AT&T Entities under Section 11.1(a) shall not exceed $150,000,000 (the "AT&T Cap"); provided that the AT&T Cap shall not apply to breaches of the representations and warranties in Sections 6.1, 6.2, 6.3(a), 6.3(b) or 6.17. -84-

(b) The Comcast Entities will have no liability under Section 11.2(a) unless the amount of Losses otherwise subject to their indemnification obligations thereunder exceeds $17,500,000 (the "Comcast Minimum Damage Requirement"), in which case the Comcast Entities shall be liable only for such excess; provided that the Comcast Minimum Damage Requirement will not apply to any Losses resulting from or arising out of breaches of the representations and warranties in Sections 5.1, 5.2, 5.3(a), 5.3(b) or 5.17. The maximum liability of the Comcast Entities under Section 11.2(a) shall not exceed $150,000,000 (the "Comcast Cap"); provided that the Comcast Cap shall not apply to breaches of the representations and warranties in Sections 5.1, 5.2, 5.3(a), 5.3(b) or 5.17. (c) The representations and warranties of any Comcast Entity and any AT&T Entity in this Agreement and any Transaction Document, and the corresponding indemnification obligations under Sections 11.1(a) and 11.2(a) will survive Closing for a period of nine months. Notwithstanding the foregoing, the liability of the parties will extend beyond the nine-month period following Closing with respect to any claim which has been asserted in a bona fide written notice before the expiration of such nine-month period specifying in reasonable detail the facts and circumstances giving rise to such right. The indemnification obligations under Sections 11.1(b) and 11.2(b) (in each case, other than the covenants, agreements and obligations which by their terms are to be performed after the Closing) and under Sections 11.1(c) and 11.2(c) will survive Closing for a period of 12 months. Notwithstanding the foregoing, the liability of the parties will extend beyond the 12-month period following Closing with respect to any claim which has been asserted in a bona fide written notice before the expiration of such 12-month period specifying in reasonable detail the facts and circumstances giving rise to such right. For this purpose, proper and timely notice shall be deemed given by all indemnified persons on the date hereof, and no further notice shall be required, with respect to all items set forth on the disclosure schedules provided by the Parties in connection with this Agreement and with respect to pre-Closing accounts payable and franchise fees for which a Transferor is responsible under Section 7.23. 11.5. Payments for Indemnification Amounts. Amounts payable by a Party in respect of any Losses that are subject to the indemnification obligations of such Party under Section 11.1 or 11.2 will be payable by the Indemnifying Party within five days of receiving written notice of such Losses from the Indemnified Party, and will bear interest at the rate per annum publicly announced from time to time by The Bank of New York as its prime rate (the "Prime Rate") plus three percent (3%) beginning on the sixth day after receipt of such written notice and ending on the date of payment of indemnification by the Indemnifying Party. 11.6. Exclusive Remedy. The Parties hereby agree that the rights set forth in this Article 11 shall be each Party's sole and exclusive remedies against the other Party for any claims arising after the Closing Time and relating to any liability of a System arising prior to the Closing Time. 12. MISCELLANEOUS PROVISIONS. 12.1. Parties Obligated and Benefited. Subject to the limitations set forth below, this Agreement will be binding upon each of the Parties and their respective assigns and successors -85-

in interest and will inure solely to the benefit of the Parties and their respective assigns and successors in interest, and no other Person will be entitled to any of the benefits conferred by this Agreement. Without the prior written consent of the other Parties, no Party will assign any of its rights under this Agreement or delegate any of its duties under this Agreement, provided that the appropriate Party may assign any or all of its rights under this Agreement to a "qualified intermediary" engaged by such Party to effectuate a deferred like-kind exchange under Section 1031 of the Code, and the other Party agrees, in connection with such an assignment, to take such actions and execute such documents as may be reasonably requested by the assigning Party in order to facilitate such Party's intent to effectuate a deferred like-kind exchange; provided, however, that no such assignment will affect the assigning Party's liabilities or obligations pursuant to this Agreement. 12.2. Notices. Any notice, request, demand, waiver or other communication required or permitted to be given under this Agreement to any Party will be in writing and will be deemed to have been duly given only if delivered in person or by first class, prepaid, registered or certified mail, or delivered by courier or, if receipt is confirmed, delivery by telecopier: To any AT&T Entity: 295 North Maple Avenue Basking Ridge, New Jersey 07920 Attention: Marilyn Wasser Telecopy: 908-221-6618 With a copy to: Wachtell, Lipton, Rosen & Katz 51 West 52nd Street New York, New York 10019 Attention: Richard D. Katcher Steven A.

With copies (which shall not constitute notice) to: Davis Polk & Wardwell 450 Lexington Avenue New York, New York 10017 Attention: William L. Taylor Telecopy: 212-450-4800 Any Party may change the address to which notices are required to be sent by giving notice of such change in the manner provided in this Section 12.2. All notices will be deemed to have been given on the date of delivery which in the case of deliveries by telecopier will be the date of the sender's confirmation (or, if delivered after business hours, on the next Business Day). 12.3. Right to Specific Performance. Each Party acknowledges that the unique nature of the Assets to be exchanged hereunder pursuant to this Agreement renders money damages an inadequate remedy for the breach by any Party of its obligations under this Agreement, and the Parties agree that in the event of such breach, the Parties will upon proper action instituted by either of them, be entitled to a decree of specific performance of this Agreement or other equitable relief. 12.4. Waiver. This Agreement or any of its provisions may not be waived except in writing. The failure of any Party to enforce any right arising under this Agreement on one or more occasions will not operate as a waiver of that or any other right on that or any other occasion. 12.5. Captions. The captions of this Agreement are for convenience only and do not constitute a part of this Agreement. 12.6. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York (other than its rules of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby). 12.7. Time. Time is of the essence under this Agreement. If the last day permitted for the giving of any notice or the performance of any act required or permitted under this Agreement falls on a day which is not a Business Day, the time for the giving of such notice or the performance of such act will be extended to the next succeeding Business Day. 12.8. Late Payments. Except as otherwise provided herein, if any Party fails to pay the other any amounts when due under this Agreement, the amounts due will bear interest from the due date to the date of payment at the Prime Rate plus 2%, adjusted as and when changes in the Prime Rate are made. 12.9. Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original. 12.10. Entire Agreement. This Agreement (including the Transaction Documents and the Schedules and Exhibits referred to in this Agreement, which are incorporated in and -87-

constitute a part of this Agreement), contains the entire agreement of the Parties with respect to the subject matter hereof, and supersedes all prior oral or written agreements and understandings with respect to such subject matter, including, without limitation, (i) the letter agreement, dated May 4, 1999, between AT&T Corp. and Comcast Corporation (but shall not supersede the following paragraphs thereof: paragraph 2 {Termination of the Merger Agreement}, paragraph 11.(b) {No Trading During Valuation Period}, paragraph 12 {Telephony Agreements} and, to the extent related to the foregoing, paragraphs 14, 15, 17, and 19-24) and (ii) the Amendment to such letter agreement dated as of November 16, 1999 (but shall not supersede paragraph 4 thereof). This Agreement does not supersede the Letter Agreement to the extent relating to the Group Three Systems and the transactions with respect thereto. The cable systems that are referenced in the Letter Agreement as Group Two Systems and Group Three Systems (other than Chesterfield, Virginia) that are not Systems for purposes hereof will be treated as Group Three Systems for purposes of the Letter Agreement and for purposes of Section 8.1 hereof and this Section 12.10. This Agreement may not be amended or modified, except by a writing signed by all of the Parties hereto. This Section 12.10 is subject to Section 10.1.4. 12.11. Severability. Any term or provision of this Agreement that is invalid or unenforceable will be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining rights of the Person intended to be benefitted by such provision or any other provisions of this Agreement. 12.12. Construction. This Agreement has been negotiated by the Parties and their respective legal counsel, and legal or other equitable principles that might require the construction of this Agreement or any provision of this Agreement against the Party drafting this Agreement will not apply in any construction or interpretation of this Agreement. 12.13. Expenses. Except as otherwise expressly provided in this Agreement, each Party will pay all of its expenses, including attorneys' and accountants' fees, in connection with the negotiation of this Agreement, the performance of its obligations and the consummation of the transactions contemplated by this Agreement. 12.14. Risk of Loss. The risk of any loss or damage to the Comcast Assets or the AT&T Assets resulting from fire, theft or other casualty (except reasonable wear and tear) will be borne by the owner thereof at all times prior to the Closing Time. In the event of any such loss or damage after May 4, 1999, Comcast Corporation or AT&T Corp., as appropriate, will immediately notify the other in writing of that fact and the System Value for the applicable System or Systems will be reduced in the amount of the deductible under the casualty insurance policies insuring such Assets, and all insurance proceeds paid or payable as a result of the occurrence of the event resulting in such loss or damage will be delivered at the Closing by the Party transferring such Assets to the Party receiving such Assets, or the rights thereto will be assigned, if not yet paid over by the insurer, to the Party transferring such Assets. If such loss is not fully insured for replacement cost, then the System Value for the applicable System or Systems will further be reduced by the cost to repair or replace such Assets, less any insurance proceeds paid or payable with respect thereto. In either case, the obligations under this Section 12.14 to make adjustment or pay or assign insurance proceeds will not apply to the extent that any insurance proceeds or deductibles are applied to replace or restore such loss or damage prior to Closing. -88-

If, on or prior to the Closing Time, all or any part of or interest in the Comcast Assets or the AT&T Assets, as appropriate, is taken or condemned as a result of a Governmental Authority's exercise of its powers of eminent domain, or if a Governmental Authority having such power informs a Party that it intends to condemn all or any part of such Party's Assets (such event being called, in either case, a "Taking"), then (i) AT&T Corp., in the case of a Taking of Comcast Assets, or Comcast Corporation, in the case of a Taking of AT&T Assets, may elect, in the name of the other Party, to negotiate for, claim, contest and receive all damages with respect to the Taking, (ii) the Party whose Assets were the subject of the Taking will be relieved of its obligation to convey to the other Party those of its Assets that were the subject of the Taking, (iii) at the Closing, the Party whose Assets were the subject of the Taking will assign to the other Party all of its rights to damages payable as a result of the Taking, and will pay to the other Party all damages previously paid to it in connection with the Taking, and (iv) following the Closing, the Party whose Assets were the subject of the Taking will give to the other Party any further assurances of such rights and assignment with respect to the Taking as the other Party reasonably may request from time to time. No amount payable under this Section 12.14 will be taken into account in calculating the Working Capital Adjustment Amount. 12.15. Tax Consequences. No Party makes any representation or warranty, express or implied, with respect to the Tax implications of any aspect of this Agreement on any other Party, and each Party expressly disclaims any such representation or warranty with respect to any Tax consequences arising under this Agreement. Each Party has relied solely on its own Tax advisors with respect to the Tax implications of this Agreement. 12.16. Jurisdiction. Except as otherwise expressly provided in this Agreement, the Parties agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement, the Transaction Documents or the transactions contemplated hereby or thereby may be brought in the United States District Court for the Southern District of New York or any other New York State court sitting in New York City, and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each Party agrees that service of process on such Party as provided in Section 12.2 shall be deemed effective service of process on such Party. 12.17. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

THE INTERNAL RESTRUCTURING AND THE REORGANIZATION. 2.1. The Internal Restructuring. AT&T will, and will cause its Affiliates to, effect an internal restructuring (the "Internal Restructuring") to achieve the following results immediately prior to the Closing Time: (a) Each AT&T Asset existing immediately prior to Closing shall be owned by a Transferred Entity, subject to Section 7.7. (b) No Transferred Entity shall own (i) any AT&T Excluded Assets or (ii) any other assets except for AT&T Assets and ownership interests in any other Transferred Entity. (c) Each of the Comcast Assumed Obligations and Liabilities shall be assumed by a Transferred Entity (to the extent not already an obligation of such entity). (d) No Transferred Entity shall have (i) any AT&T Excluded Liability or (ii) any other liabilities except for the Comcast Assumed Obligations and Liabilities. 15

(e) Each Hired Employee shall be employed by a Transferred Entity subject to Section 7.5. (f) No Transferred Entity shall have any employees except for Hired Employees. With respect to any entity that owns any AT&T Assets, but that is not a Party to this Agreement, AT&T will cause such entity to comply with the obligations, covenants and terms of this Agreement in respect of such AT&T Assets as if such entity were a Party to this Agreement. 2.2. The Reorganization. Subject to the terms and conditions of this Agreement, on the Closing Date, AT&T shall redeem all of the Total Closing Shares in consideration of the transfer and distribution to CCCI, as agent for the other Comcast Entities, of all of the issued and outstanding capital stock of the AT&T Cable Subsidiaries (the "AT&T Cable Subsidiaries Shares") as follows: 2.2.1. AT&T shall assign, transfer, convey and deliver to CCCI, as agent for the other Comcast Entities, all of the AT&T Cable Subsidiaries Shares, free and clear of all Liens and any other limitation or restriction (including any restriction on the right to sell, vote or otherwise dispose of the AT&T Cable Subsidiaries Shares). Such assignment, transfer, conveyance and delivery shall be evidenced by duly endorsed in blank share certificates or by instruments of transfer, with any required transfer stamps affixed thereto, reasonably satisfactory in form and substance to Comcast and its counsel; and 2.2.2. The Comcast Entities shall assign, transfer, convey and deliver to AT&T all of the Total Closing Shares, free and clear of all Liens and any other limitation or restriction (including any restriction on the right to sell, vote or otherwise dispose of the Total Closing Shares). Such assignment, transfer, conveyance and delivery shall be evidenced by duly endorsed in blank share certificates or by instruments of transfer, with any required transfer stamps affixed thereto, reasonably satisfactory in form and substance to AT&T and its counsel. 3. ALIGNMENT MECHANISM. Each Party hereto agrees as follows: 3.1. Calculation of Values. 3.1.1. For purposes of this Agreement, (i) each Original Share shall be valued at $54.41, (ii) each Recently Purchased Share shall be valued at the purchase price paid by Comcast or its wholly-owned Affiliate for such Recently Purchased Share and (iii) each Hunter Share shall be valued at $48.8125. In each case, such share values shall be subject to adjustment as provided in Section 7.31. The term "Agreed Share Value" means, with respect to any AT&T Share, the per share value specified in the first sentence of this Section 3.1.1, as adjusted pursuant to Section 7.31. 3.1.2. For the purposes of this Agreement, the "System Value" for each System shall equal (a) $4,591 multiplied by (b) the number of Equivalent Basic Subscribers served by such System as of the month end prior to the Closing Date (or, in the case of any franchise area located in Wildwood, New Jersey, the average number of Equivalent Basic Subscribers in such area for the twelve (12)-month period ending on the month end prior to the Closing Date, 16

calculated by (x) adding together the number of Equivalent Basic Subscribers in such area at the end of each of the thirteen (13) months ending on the month end prior to the Closing Date and (y) dividing that aggregate number by thirteen (13)); provided that, with respect to each such System, the number of Equivalent Basic Subscribers in such System shall not exceed the number (the "Subscriber Cap") set forth for such System in Schedule 3.1.2-A. 3.2. Working Capital Adjustment. A working capital adjustment amount shall be calculated for each AT&T System on an AT&T System-by-AT&T System basis as follows, which adjustments will be made without duplication of any amount (in each case, the "Working Capital Adjustment Amount"). The Working Capital Adjustment Amount for each System shall initially be zero and shall be increased by the amount of current assets (other than inventory) being Transferred to the Comcast Entities with respect to such AT&T System and decreased by the amount of liabilities being Transferred to such Comcast Entities with respect to such System as of the Closing Time. Current assets shall include, but are not limited to, petty cash, prepaid expenses, funds of Transferred Entities on deposit with Third Parties to the extent being Transferred to the Comcast Entities (other than those that are or relate to AT&T Excluded Assets or the benefit of which will not be available to the Transferred Entity following Closing), and accounts receivable, and liabilities shall include, but are not limited to, accrued expenses (including accrued real and personal property taxes, but not other Taxes, and including copyright fees or non-programming license fees or charges), unearned income and advance payments (including subscriber prepayments and deposits for converters, encoders, cable television service and related sales) and interest, if any, required to be paid on advance payments, in each case, related to AT&T's Cable Business conducted through such System, all as determined in accordance with GAAP, to reflect the principle that all expenses and income attributable to AT&T's Cable Business for the period through and including the Closing Time are for the account of AT&T or its applicable subsidiary, and all expenses and income attributable to AT&T's Cable Business for the period after the Closing Time are for the account of the Comcast Entities (through ownership of the Transferred Entities). AT&T will receive no credit for (i) the portion of any account receivable resulting from cable, telephony or Internet service sales that is sixty (60) days or more past due as of the Closing Date (cash received subsequent to the billing cutoff prior to the Closing Time will be applied to the active aged receivables on a pro rata basis), (ii) the portion of any national agency account receivable resulting from advertising sales that is one hundred twenty (120) days or more past due as of the Closing Date, (iii) any non-national agency account receivable resulting from advertising sales any portion of which is ninety (90) days or more past due as of the Closing Date, (iv) accounts receivable from customers whose accounts are inactive as of the Closing Date, or (v) any accounts receivable that have not arisen from a bona fide transaction in the ordinary course of business. For purposes of making "past due" calculations under this Section 3.2, the billing statements of a System will be deemed to be due and payable on the first day of the period during which the service is provided to which such billing statements relate. Notwithstanding the foregoing, no adjustment will be made for any items of income or expense to the extent related to AT&T Excluded Assets or AT&T Excluded Liabilities. In furtherance of the foregoing, the Working Capital Adjustment Amount for each System shall be decreased without duplication by the economic value of vacation time pursuant to Section 7.5.8(a) to the extent earned as of the Closing Time and permitted to be taken after the Closing Time by the AT&T System Employees employed at such AT&T System who (i) are employed by a Transferred Entity at Closing or (ii) will become employees of a Transferred Entity, after being released from a leave of absence in accordance 17

with Section 7.5.3. It is understood that the Working Capital Adjustment Amount will not reflect any intercompany receivables or payables, long-term debt (including the current portion thereof) or related accrued interest, accrued programming expense, accounts payable, franchise fees or deferred taxes, as these items will not be Transferred with the AT&T Systems. 3.3. Preliminary Alignment of Systems. 3.3.1. After the date hereof, Comcast and AT&T will consult with each other from time to time regarding the progress being made towards satisfaction of the conditions to Closing set forth in Article 8. The date upon which all the conditions to the Closing set forth in such Article have been satisfied or (to the extent legally permissible) waived or are then capable of being satisfied, and one Parent has delivered the other Parent a notice thereof, is referred to as the "Condition Satisfaction Date." Except as otherwise provided herein, a Party may (to the extent legally permissible) conditionally waive one or more conditions to its obligations, subject to the Closing occurring on the last Business Day of the month after the month in which notice of the Condition Satisfaction Date is provided. 3.3.2. Within 10 Business Days after the end of the month in which the Condition Satisfaction Date occurs, AT&T shall deliver to Comcast a report (a "Preliminary Report"), certified as to completeness and accuracy by an authorized officer of AT&T, showing in reasonable detail for each AT&T Cable Subsidiary a good faith preliminary determination of (i) the System Value for each System owned or to be owned at Closing by the applicable AT&T Cable Subsidiary or by any of its Subsidiaries that is a Transferred Entity, (ii) the Working Capital Adjustment Amount of each such System, (iii) the aggregate of items (i) and (ii) for all AT&T Cable Subsidiaries (the "Preliminary Aggregate Value"), in each case together with appropriate documents substantiating the estimates proposed in its Preliminary Report and (iv) an amount determined by AT&T (the "Cushion Value"), which Cushion Value shall not exceed $25 million or be less than zero. 3.3.3. The Closing will occur on the last Business Day of the month during which the Preliminary Report must be delivered (the "Closing Date"); provided that if the Closing does not occur on such date as a result of the failure of the conditions set forth in Article 8 to be satisfied or (to the extent legally permissible) waived, the provisions of this Section 3.3 shall continue to apply as if the original Condition Satisfaction Date had not occurred; and provided further that the Parents may mutually agree upon a different Closing Date. 3.3.4. The Comcast Entities shall deliver to AT&T at Closing in the aggregate a number of AT&T Shares with a value (based on the Agreed Share Value) equal to the Preliminary Aggregate Value; provided that the following conditions shall be satisfied (and if they are not satisfied, the procedure set forth in Section 3.3.5 shall apply): (a) the total number of Disqualified Shares (i) shall be less than the total number of Qualified Shares (the "Number Cap") and (ii) shall be further reduced by a number of AT&T Shares (the "Cushion Shares") equal to the Cushion Value divided by the average daily closing price (the "Average Price") per AT&T Share for the five (5) day trading period ending on the trading-day prior to the delivery of the Preliminary Report (as reported in the Wall Street Journal, or if no market price for an AT&T Share (or element thereof) existed on any such 18

trading day, the price for an AT&T Share (or such element) as estimated in good faith by AT&T); and (b) the total value of the Disqualified Shares (based on the Agreed Share Value) (i) shall be less than the total value of Qualified Shares (based on the Agreed Share Value) (the "Value Cap") and (ii) shall be further reduced by the Cushion Value. During the period from the date upon which the Preliminary Report is required to be delivered through no later than the close of business on the 20th day (or, if the 20th day is not a Business Day, the previous Business Day) in that same calendar month, Comcast or its Affiliates will acquire (to the extent not previously acquired) additional AT&T Shares to achieve (based on the Agreed Share Value), to the maximum extent possible, the Preliminary Aggregate Value consistent with the conditions set forth in clauses (a) and (b) of the previous sentence (the "Designated Conditions"), less a number of AT&T Shares determined by Comcast (the "Pullout Shares") which number will not exceed $23 million divided by the Average Price. By no later than the first Business Day after the end of such period, Comcast shall deliver to AT&T a report (a "Share Report"), certified as to completeness and accuracy by an authorized officer of Comcast showing in reasonable detail (i) all AT&T Shares owned by Comcast or its wholly-owned Affiliates, (ii) the share prices paid for Recently Purchased Shares and (iii) sufficient information to demonstrate whether such shares achieve the Preliminary Aggregate Value and sufficient information to demonstrate that such shares, together with the Pullout Shares, if any, would satisfy the Designated Conditions. In accordance with Section 7.31, the Parties agree that after the record date for a Distribution, any reference in this Agreement to "AT&T Share", "Total Closing Share," "Original Share", "Hunter Share", "Disqualified Share" or "Qualified Share", or the price or value thereof, shall include the applicable Tracking Share(s) (or portion thereof) and the price or value thereof, respectively. 3.3.5. If, based on the Share Report, the Preliminary Aggregate Value cannot be achieved consistent with the Designated Conditions, within four Business Days after delivery of the Share Report AT&T shall select one or more Systems or franchise areas, at its option subject to the following proviso, to be removed from and not Transferred pursuant to this Agreement (the "Removed Systems"), such that the revised Preliminary Aggregate Value (based on the Preliminary Aggregate Value without the Removed Systems and based on the information set forth in the Share Report) is achievable consistent with the Designated Conditions; provided that AT&T shall remove Systems and franchise areas such that, after giving effect to such removal, the revised Preliminary Aggregate Value shall be no less than (x) the aggregate Agreed Share Value of all AT&T Shares reflected in the Share Report plus (y) the Pullout Shares multiplied by the Average Price minus (z) $23 million. The Parties will cooperate in good faith and take all necessary action to effect the adjustments contemplated by this Section 3.3.5, including exchanging a revised Preliminary Report and a revised Share Report to reflect such adjustments and amending Schedule 2.1. The Parties will negotiate in good faith and enter into mutually acceptable arrangements on commercially reasonable terms to address all issues and concerns regarding the separation of the Removed Systems from the remaining Systems that will result at Closing because of this Section 3.3.5, including the terms on which the applicable Parent's Affiliates, from and after the Closing Date, would provide to the other Parent's Affiliates such 19

signal delivery, management and other support services as may be necessary or appropriate due to such separation. 3.3.6. At Closing, the AT&T Shares delivered by the Comcast Entities to AT&T shall have a value (based on the Agreed Share Value) equal to the Preliminary Aggregate Value (as adjusted pursuant to Section 3.3.5) and shall satisfy all of the Designated Conditions (the "Total Closing Shares"), as set forth in a final share report delivered by Comcast at Closing (the "Final Share Report"), certified as to completeness and accuracy by an authorized officer of Comcast. The Total Closing Shares shall be deemed to include any Tracking Shares which are issued after the Closing pursuant to a record date occurring prior to Closing in respect of shares delivered by the Comcast Entities to AT&T at Closing. The Comcast Entities shall deliver such Tracking Shares to AT&T promptly upon receipt thereof. 3.4. Determination of Final System Values and Working Capital Adjustment Amounts. 3.4.1. Within ninety (90) days after the Closing, AT&T will deliver to Comcast a report (the "Final Report"), certified as to completeness and accuracy by an authorized officer of AT&T, showing in full detail for each AT&T Cable Subsidiary transferred at Closing AT&T's final determination of (i) the System Value for each System owned at the Closing by such AT&T Cable Subsidiary or by any of its Subsidiaries that is a Transferred Entity, (ii) the Working Capital Adjustment Amount of each such System, and (iii) the aggregate of items (i) and (ii) for all AT&T Cable Subsidiaries, which may include any adjustments that were not calculated as of the Closing Time or which are corrective of any estimated adjustments contained in the Preliminary Report, together with appropriate documents substantiating the determinations proposed in its Final Report. Comcast will provide AT&T with reasonable access to all records that Comcast has in its or its Affiliates' possession and that are necessary for AT&T to prepare the Final Report. 3.4.2. Within sixty (60) days after receipt of the Final Report from AT&T, Comcast will give AT&T written notice of Comcast's objections, if any, to the Final Report. The Parents shall negotiate in good faith for a period of thirty (30) days, or such longer period of time as agreed by the Parents, to resolve any disputed items. If, after such thirty (30) day period (as extended, if applicable), the Parents fail so to resolve such disputed items, the Parents shall submit all then-outstanding disputed items for resolution by a national accounting firm acceptable to each Parent (or, if the Parents cannot agree, an arbitrator appointed by the American Arbitration Association) (the "Arbitrator"). As to each item in dispute, the Arbitrator's decision must be within the range of values proposed by the Parents. The Arbitrator shall render a decision within thirty (30) days after its selection, which decision shall be final and binding on the Parties hereto. Comcast and AT&T shall share equally the expenses of the Arbitrator. 3.4.3. (a) Based upon a final determination of each item relating to the Final Report (determined either (x) as set forth in the Final Report, if Comcast raised no objection or (y) by agreement of the Parents or decision of the Arbitrator as set forth above), the Parties shall calculate for each AT&T Cable Subsidiary (i) the System Value for each System owned at the Closing by such AT&T Cable Subsidiary or by any of its Subsidiaries that is a Transferred Entity 20

and (ii) the Working Capital Adjustment Amount of each such System (for each AT&T Cable Subsidiary and its Subsidiaries, the "Final Aggregate Value"). If with respect to any given AT&T Cable Subsidiary and its Subsidiaries, the Final Aggregate Value exceeds the portion of the Preliminary Aggregate Value (as it may have been adjusted pursuant to Section 3.3.5) attributable to such AT&T Cable Subsidiary and its Subsidiaries, such AT&T Cable Subsidiary will pay AT&T cash in an amount equal to such excess. If with respect to any given AT&T Cable Subsidiary and its Subsidiaries, the value of the portion of the Preliminary Aggregate Value (as it may have been adjusted pursuant to Section 3.3.5) attributable to such AT&T Cable Subsidiary and its Subsidiaries exceeds the Final Aggregate Value, AT&T will pay such AT&T Cable Subsidiary cash in an amount equal to such excess. Any such adjusting payments shall be made, together with interest thereon calculated from the Closing Date through the date of payment at the Prime Rate and paid in cash as set forth in this Section 3.4.3, within three (3) Business Days after calculation of the Final Aggregate Value. Notwithstanding any other provision of this Agreement, no AT&T Cable Subsidiary shall make any payment to AT&T pursuant to this Section 3.4.3(a) unless and only to the extent instructed to do so by AT&T and AT&T shall be entitled to rely upon the Final Share Report in determining whether to instruct any AT&T Cable Subsidiary to make such payment.

ownership, leasing or use of the AT&T Assets owned, leased or used by it or the nature of its activities in connection with its AT&T Systems makes such qualification necessary, except for such matters as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. For purposes of this Agreement, "Material Adverse Effect" means a material adverse effect on the business, assets, financial condition or results of operations of AT&T's Cable Business, taken as a whole (excluding such effects to the extent relating to the liabilities or assets to be retained by any Retained Entity after Closing under this Agreement or the Internal Restructuring Documents), without giving effect to the transaction contemplated by this Agreement or the announcement thereof or changes in conditions that are applicable to the cable television industry in general.

At Closing, AT&T will transfer and deliver to the Comcast Entities valid title to the AT&T Cable Subsidiaries Shares free and clear of all Liens and any other limitation or restriction (including any restriction on the right to sell, vote or otherwise dispose of such interest). 6.4.

Schedules 6.6.4(e) and 6.6.4(f) list all of the AT&T Systems Franchises and all AT&T Systems Licenses, respectively. Complete and correct copies of the AT&T Systems Franchises, all AT&T Systems Licenses issued by the FCC and any other material AT&T Systems Licenses have been provided to Comcast. Except as set forth on Schedule 6.7.2, the AT&T Systems Franchises contain all of the commitments and obligations of the Transferred Entities, AT&T or its Affiliates to the applicable Governmental Authority granting such AT&T Systems Franchises with respect to the construction, ownership and operation of the AT&T Systems, including any commitment to any local franchising authority to make any material expenditure or capital addition or betterment to any of the AT&T Systems or AT&T Assets that will not be fulfilled or satisfied prior to the Closing Time. The AT&T Systems Franchises and AT&T Systems Licenses are currently in full force and effect, are not in default and are valid under all applicable Legal Requirements according to their terms. No event has occurred that, with notice or lapse of time or both, would constitute a breach, violation or default by any Transferred Entity, and to AT&T's Knowledge, no event has occurred that, with notice or lapse of time or both, would constitute a breach, violation or default by any other Person, of any material obligations under any of the AT&T Systems Franchises or AT&T Systems Licenses, and would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Except for routine filings with Governmental Authorities or as described on Schedule 6.7.2, there are no material applications relating to any AT&T Systems Franchise or AT&T Systems License pending before any Governmental Authority. Since January 1, 1999, no AT&T Systems Franchise or AT&T Systems License has been surrendered or has otherwise terminated 30

without the issuance of a replacement AT&T Systems Franchise or AT&T Systems License, respectively. There is no legal action, governmental proceeding or investigation pending or, to AT&T's Knowledge, threatened to terminate, suspend or modify any AT&T Systems Franchise or AT&T Systems License. Except as set forth on Schedule 6.7.2, each AT&T System is operating pursuant to a valid franchise or similar authorization or permit issued by the appropriate Governmental Authority in every market in which such System is supplying cable television service. Prior to the date hereof, AT&T has provided a list to Comcast of the date on which each AT&T System Franchise will expire. Such list is correct and accurate in all material respects. Neither AT&T, nor any Transferred Entity or Retained Entity has received, nor does it have notice that it will receive, from any Governmental Authority a preliminary assessment that an AT&T Systems Franchise should not be renewed as provided in Section 626(c)(1) of the Cable Act. Neither any Transferred Entity or Retained Entity nor any Governmental Authority has commenced or requested the commencement of an administrative proceeding concerning the renewal of an AT&T Systems Franchise as provided in Section 626(c)(1) of the Cable Act. The Transferred Entities or the Retained Entities have timely filed notices of renewal in accordance with the Cable Act with all Governmental Authorities with respect to each of the AT&T Systems Franchises expiring within thirty-six (36) months of the date of this Agreement. Such notices of renewal have been filed pursuant to the formal renewal procedures established by Section 626(a) of the Cable Act. Except as set forth on Schedule 6.7.2, and except for such matters as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, the AT&T Systems are being operated in material compliance with the terms and conditions of all AT&T Systems Franchises and AT&T Systems Licenses and other applicable requirements of all Governmental Authorities (including the FCC and the United States Copyright Office) relating to such AT&T Systems Franchises and AT&T Systems Licenses, including all requirements for notification, filing, reporting, posting and maintenance of logs and records. 6.7.3. AT&T has delivered to Comcast true and complete copies of all Material AT&T Systems Contracts, including any amendments thereto (or, in the case of oral Contracts that are Material AT&T Systems Contracts, true and complete written summaries thereof) and each document evidencing or insuring ownership of the AT&T Owned Property. Except as described on Schedule 6.7.3 and except for such matters as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, (i) each Transferred Entity has fulfilled when due, or has taken all action necessary to enable it to fulfill when due, all of such Person's obligations under each of its Material AT&T Systems Contracts, (ii) to AT&T's Knowledge, there has not occurred any default (without regard to requirements of notice, lapse of time, elections of other Persons or any combination thereof) by any Person of any material obligations under any Material AT&T Systems Contracts and (iii) to AT&T's knowledge, the Material AT&T Systems Contracts are valid and binding agreements of the applicable Third Party to the Material AT&T Systems Contracts, and, assuming that the Material AT&T Systems Contracts are valid and binding agreements on the applicable Third Party, the Material AT&T Systems Contracts are valid and binding agreements of the applicable Transferred Entity and are in full force and effect. 6.7.4. Except as disclosed on Schedule 6.7.4, none of the AT&T Systems or material AT&T Assets are subject to any purchase option, right of first refusal or similar arrangement which would be triggered by the sale, transfer, change of control or other disposition of such Systems or Assets (an "AT&T System Option"). 31

6.7.5. Set forth on Schedule 6.7.5 is each lease for vehicles and each capital lease that, in either case, would be an AT&T Asset but for the effect of Section 7.6. 6.8. Real Property.

Except as set forth on Schedule 7.2 or as Comcast may otherwise consent in writing (which consent shall not unreasonably be withheld), between the date of this Agreement and the Closing, each Transferred Entity (and each Retained Entity to the extent owning a System prior to Closing) will with respect to AT&T's Cable Business, the AT&T Systems and the AT&T Assets: 7.2.1. conduct AT&T's Cable Business in good faith and operate the AT&T Systems only in the usual, regular and ordinary course, including making capital expenditures, completing ongoing and planned line extensions, placing conduit or cable in new developments, commencing and continuing planned upgrades, fulfilling installation requests, completing disconnection work orders and disconnecting and discontinuing service to customers whose accounts are delinquent, and (a) use its reasonable best efforts to preserve its current business intact in all material respects, including preserving existing relationships with franchising authorities, suppliers, customers and others having business dealings with the AT&T Systems, (b) use its reasonable best efforts to keep available the services of its employees and agents taken as a whole, providing services in connection with AT&T's Cable Business, but will be under no obligation to incur costs to do so, (c) not, outside of the ordinary course of business consistent with normal salary reviews, grant or agree to grant an increase in the rate of compensation of, or any increase in any severance, profit sharing, retirement, deferred compensation, insurance or other compensation or benefits for, such System employees, except as a result of amendments or modifications to employee compensation and benefit plans and programs of AT&T which benefit broad classes of AT&T's employees generally, (d) make customary marketing, advertising and promotional expenditures with respect to AT&T's Cable Business, and (e) use its 41

No Transfer of Qualified Shares. Until Closing (or termination of this Agreement), the Comcast Parties will not sell, assign, transfer or otherwise dispose of any of the Qualified Shares other than in connection with the transactions contemplated in this Agreement or corporate transactions engaged in by AT&T. 7.5. Employees. 7.5.1. No later than November 15, 2000, which date may be amended by mutual agreement of the Parties, AT&T shall provide to Comcast a list of all the AT&T System Employees by work location as of a recent date, showing the original hire date, the then-current positions, the rates of compensation, rate type (hourly or salary), schedule hours per week, 44

whether the AT&T System Employee is subject to an employment agreement or a collective bargaining agreement or is represented by a labor organization, and if the employee is a term employee or Senior Manager. The list shall also indicate which of the AT&T System Employees, AT&T or its Affiliates desire to retain as employees (the "Retained Employees") after the Closing. Comcast shall maintain such list in strict confidence. Such list shall be updated as necessary to reflect new hires or other personnel changes. 7.5.2. AT&T agrees, and shall cause AT&T's appropriate Affiliates, to cooperate in all reasonable respects with Comcast to allow Comcast or Comcast's Affiliates to evaluate the AT&T System Employees including the right to review personnel files and the right to interview the AT&T System Employees during normal working hours so long as such interviews are conducted after notice to AT&T and do not unreasonably interfere with AT&T's operations and such investigations and interviews do not violate any law or contract. AT&T and Comcast will cooperate on the timing of such evaluation and interviews but agree that such evaluation will begin no earlier than the date AT&T delivers the list required of AT&T pursuant to Section 7.5.1. AT&T shall use its reasonable commercial efforts to resolve (or to cause its Affiliates to resolve) at its own expense each Documented Employee Performance Case. 7.5.3. The Transferred Entities shall employ commencing immediately after the Closing (or immediately after the return to active service or, if earlier, following expiration of the Approved Leave of Absence, as provided below for Employees on Approved Leave of Absence) all Other Employees, excluding Retained Employees, employees on long-term disability as of the Closing Date, and excluding any employee whose employment was previously terminated for cause by AT&T or an Affiliate of AT&T. The Transferred Entities, as directed by Comcast, may, but are not required to, employ Senior Managers commencing on the date set forth in the preceding sentence. In connection therewith, AT&T and Comcast agree that, no later than January 15, 2001 (which date may be amended by mutual consent of the Parties), Comcast shall give AT&T a list of AT&T System Employees (still employed by AT&T or an affiliate of AT&T at the time) (a "List") to whom Comcast intends to employ or cause the Transferred Entities to employ pursuant to the preceding sentences. Comcast may, if it wishes, and subject to applicable law, condition such employment of those AT&T System Employees on the List by the Transferred Entities upon the AT&T System Employee being in active service on the Closing Date, the AT&T System Employee's passing a pre-employment drug screening test, the completion of a satisfactory background check, and resolution of any Documented Employee Performance Case identified pursuant to Section 7.5.2, provided, however, that the determination of whether a Documented Employee Performance Case has been resolved shall be made in the sole discretion of Comcast. Comcast shall bear the expense of such examination but AT&T shall, upon reasonable notice, cooperate in the scheduling of such examinations so long as the examinations do not unreasonably interfere with AT&T's operations. Comcast shall direct the Transferred Entities to retain or offer each such AT&T System Employee on the List employment with substantially similar responsibilities, at a geographic location within a 35-mile radius of such Employee's primary place of employment and base compensation at least equal to the employee's base compensation as of the Closing Date, provided, however, that Comcast shall direct the Transferred Entities to offer each such Employee benefits and total cash compensation that, in each case, are no less favorable than the employee benefits and total cash compensation, respectively, that Comcast or Comcast's Affiliates provides for its similarly situated employees with comparable experience and length of service. In connection with the foregoing, as of the 45

Closing Time (i) AT&T shall cause all AT&T System Employees who are on the List, who satisfy the conditions for employment as described above and who are employed by AT&T or an Existing Affiliate of AT&T at Closing to be or remain employees of the Transferred Entities, as directed by Comcast and (ii) AT&T shall cause the Transferred Entities to terminate or transfer all employees that are not described in clause (i) above so that such employees are not employed by the Transferred Entities. As of the Closing, neither Comcast nor its Affiliates (including the Transferred Entities) shall have any obligation to AT&T, its Affiliates or to the AT&T System Employees, with regard to any Senior Manager and Other Employees Comcast has determined, based on such evaluations prior to Closing, not to hire or retain. Notwithstanding any of the foregoing, from the date hereof until the Closing, Comcast and each of its Affiliates agrees not to solicit for employment that would commence prior to the Closing Date (other than through advertisements directed at the relevant general population), without the written consent of AT&T, any Senior Manager. Comcast and each of its Affiliates agrees, for a period of one year from the Closing Date, not to solicit the performance of services by any Retained Employee, and AT&T and each of its Existing Affiliates agrees, for a period of one year from the Closing Date, not to solicit the performance of services by any Hired Employee; provided, however, that the foregoing provision will not prevent any Person from hiring any Retained Employee or Hired Employee as a result of placing general advertisements in trade journals, newspapers or similar publications which are not directed at such Retained Employees or Hired Employees. In the case of any AT&T System Employee (other than a Retained Employee) who is on Approved Leave of Absence as of the Closing Date (a "System Employee on Leave Status") whom Comcast or its Affiliates desires or is required to hire, an Existing Affiliate of AT&T other than a Transferred Entity shall employ such AT&T System Employee on Leave Status prior to the Closing Date, and upon the Employee's return to active service within sixteen (16) weeks after the Closing Date or, if earlier, on the first Business Day following expiration of the Employee's Approved Leave of Absence a Transferred Entity shall employ such System Employee on Leave Status. For purposes of this Agreement, employees on "Approved Leave of Absence" means employees absent from work on the Closing Date and unable to perform their regular job duties by reason of illness or injury under approved plans or policies of the employer (other than employee's absence for less than ten (10) days due to short term illness or injury not requiring written approval by the employer) or otherwise absent from work under approved or unpaid leave policies of employer. 7.5.4. As of the Closing Date, AT&T shall be responsible for, and shall cause to be discharged and satisfied in full, all amounts due and owing to each of the AT&T System Employees with respect to and in accordance with the terms of all compensation or benefit plans or arrangements, including, without limitation, any salaries, commissions, deferred compensation, severance, insurance, pension, profit sharing, disability payment, medical, holiday, sick pay, accrued and unused vacation in excess of the amount the Comcast Entities or their Affiliates assume pursuant to this Section 7.5, and payments under any incentive compensation or bonus agreement, in each case, which has accrued prior to the Closing Date (and, for System Employees on Leave Status, until their termination by AT&T or its appropriate Existing Affiliate, or their employment by Comcast, or its appropriate Affiliate, as set forth in Section 7.5.3). In addition, AT&T shall retain all liabilities and obligations associated with its employees, including Systems Employees, who are not employed by a Transferred Entity at Closing. 46

7.5.5. After the Closing Date, AT&T shall cause each of its former employees who becomes a Hired Employee to be permitted to elect to receive a distribution of the full account balances of such former employee under any Code Section 401(k) plan maintained by AT&T or its Affiliate, and Comcast shall in each case permit to the extent allowed by Code Section 402(c) the Hired Employee to roll over any amounts so distributed in cash into a Code Section 401(k) plan maintained by Comcast or its Affiliate. 7.5.6. Except as expressly stated to the contrary herein, all claims and obligations under, pursuant to or in connection with any welfare, medical, insurance, disability or other employee benefit plans of AT&T or its Affiliates or arising under any Legal Requirement affecting employees of AT&T or its Affiliates to the extent arising before the Closing Date will remain the responsibility of AT&T, or its Affiliate, whether or not such employees are retained or hired by a Transferred Entity, Comcast or any of its Affiliates as of or after the Closing. Comcast will not have nor assume any obligation or liability under or in connection with any such plan of AT&T or any of its Affiliates. For purposes of this Agreement, the following claims and liabilities shall be deemed to be incurred as follows: (i) medical, dental and/or prescription drug benefits when the treatment is provided, except with respect to such benefits provided in connection with a continuous period of hospitalization, which shall be deemed to be arising at the time of admission to the hospital; (ii) life, accidental death and dismemberment and business travel accident insurance benefits and workers' compensation benefits, upon the death, disability or accident giving rise to such benefits; and (iii) salary continuation or other short-term disability benefits, or long-term disability, upon commencement of the disability giving rise to such benefit. AT&T shall promptly satisfy any legal obligation with respect to continuation of group health coverage required pursuant to Section 4980B of the Code or Section 601, et seq., of ERISA. In regard to any System Employee on Leave Status, all liability for benefit coverage of such Employee, and liability for payment of benefits, shall remain that of AT&T, or its appropriate Existing Affiliate, until such Employee becomes an employee of Comcast or its Affiliate after the Closing pursuant to Section 7.5.3. 7.5.7. AT&T or its Affiliate will remain solely responsible for, and will indemnify and hold harmless Comcast and its Affiliates (including the Transferred Entities) from and against all Losses arising from or with respect to, all salaries, commissions, deferred compensation, severance, insurance, pension, profit sharing, disability payment, medical, sick pay, holiday, vacation (except for accrued vacation time and sick time included in the calculation of the Working Capital Adjustment Amount), medical, holiday, continuation coverage and other compensation or benefits to which its employees may be entitled, whether or not such employees may be hired by a Transferred Entity, Comcast or any of its Affiliates, to the extent arising from their employment by AT&T or any of its Affiliates on or prior to the Closing Date, the termination of their employment on or prior to the Closing Date, the consummation of the transactions contemplated hereby or pursuant to any applicable Legal Requirement or otherwise to the extent arising from their employment prior to the Closing Date (and, for System Employees on Leave Status, until their termination by AT&T, or its appropriate Affiliate, or their employment by a Transferred Entity, Comcast, or its appropriate Affiliate, as set forth in Section 7.5.1). Any liability under WARN with regard to any employee terminated on or prior to the Closing Date, or not hired by a Transferred Entity, Comcast or its Affiliates on or after the Closing Date, shall, as a matter of contract between the Parties, be the responsibility of AT&T or its Affiliates. Each Parent and such Parent's Affiliates shall cooperate with the other Parent 47

and the other Parent's Affiliates, if requested, in the giving of WARN notices on behalf of the other Parent. 7.5.8. (a) Notwithstanding anything to the contrary herein, on and after the Closing Date Comcast will cause each Transferred Entity to: (i) upon receipt of a schedule showing the vacation and sick balances and value of such balances of each Hired Employee, which schedule shall be delivered by AT&T to Comcast within ten (10) days after the Closing, credit each Hired Employee the amount of vacation and sick time permitted to be accrued by similarly situated employees of Comcast in accordance with Comcast's standard practices (to a maximum of four weeks for vacation and seven (7) days for sick time) accrued and unused by him or her as a System Employee of AT&T through and including the Closing Date to the extent the Working Capital Adjustment Amount is decreased pursuant to Section 3.2; provided, however, that, if any Hired Employee has accrued vacation and sick time in excess of the amount so credited by the Transferred Entity, then AT&T shall, and shall cause its appropriate Existing Affiliate to, pay to such employee any amount due to such employee in respect of such excess and the Transferred Entity shall not have any liability or obligation in respect of such excess; (ii) give each Hired Employee credit for such Hired Employee's past service with AT&T and AT&T's Affiliates as of the Closing Date (including past service with any prior owner or operator of the AT&T Systems or AT&T's Cable Business) (A) for purposes of eligibility to participate in Comcast's applicable employee welfare benefit plans to the same extent as similarly situated employees of Comcast and their dependents are permitted to participate; and (B) for purposes of eligibility to participate, vesting and benefit accrual under any applicable post-retirement medical or life insurance benefit plan which Comcast maintains or in which Comcast participates; (iii) give each Hired Employee credit for such Hired Employee's past service with AT&T and AT&T's Affiliates as of the Closing Date (including past service with any prior owner or operator of the AT&T Systems or AT&T's Cable Business) for purposes of eligibility for participation and vesting under the applicable 401(k) plan, or any other applicable retirement plan and stock plan in which Comcast participates to the same extent as other similarly situated employees of Comcast; (iv) give each Hired Employee credit for such Hired Employee's past service with AT&T as of the Closing Date (including past service with any prior owner or operator of the AT&T Systems or AT&T's Cable Business) for any waiting periods under the employee benefit plans, including any applicable group health and disability plans, in which Comcast participates, to the same extent as similarly situated employees of Comcast, except to the extent such employees were subject to such limitations under the employee benefit plans of AT&T or any Affiliate of AT&T; and not subject any Hired Employees to any 48

limitations on benefits for any preexisting conditions, provided that the treatment is covered under the applicable Comcast group health plans; and (v) credit each Hired Employee under any group health plan for any deductible amount previously met by such Hired Employee as of the Closing Date under any of the group health plans of AT&T or any of AT&T's Affiliates for the plan year in which the transfer of employment occurs. (c) Notwithstanding anything set forth in Section 7.5.8(a), Comcast and its Affiliates (including the Transferred Entities) shall have no obligation to the AT&T System Employees who are Employees on Leave Status until they become employees of Comcast or its and its Affiliate pursuant to Section 7.5.3. 7.5.9. Except with respect to term employees listed on Schedule 7.5.9 who become Hired Employees, if a Transferred Entity or Comcast discharges any Hired Employee without cause within one hundred eighty (180) days after the Closing, then Comcast shall pay severance benefits to such Hired Employee in accordance with AT&T's severance benefit plan (the "Severance Benefits") at the Closing Date and counting the period of employment with AT&T and Comcast for purposes of calculating benefits under such plan on the Closing Date; provided, however, that if Comcast discharges any Hired Employee who was an "Other Employee" without cause within sixty (60) days after Closing, then AT&T shall reimburse the Hiring Party for the Severance Benefits. Following such 180-day period, such Hired Employee shall be covered under Comcast's severance benefit plan counting the period of employment with the AT&T and its Affiliates and Comcast for purposes of calculating benefits under such plan on the Closing Date. Schedule 7.5.9 sets forth the terms of such severance benefit plan in effect on the date hereof, and AT&T will promptly notify Comcast of any changes in the terms of such plan occurring between the date hereof and the Closing Date. AT&T agrees that between the date of this Agreement and the Closing Date, AT&T will not increase the benefits provided under such severance plan, except as a result of, and consistent with, increases made by AT&T on a company-wide basis in the benefits provided under its severance plans. For purposes of this Section 7.5.9, "cause" shall have the meaning set forth in Comcast's employment policies, procedures or agreements applicable to Comcast's employees who are situated similarly to the discharged Hired Employee. 7.5.10. If AT&T or its Affiliate has, or acquires, a duty to bargain with any labor organization in respect of the AT&T System Employees prior to the Closing Date, then AT&T will (i) give prompt written notice of such fact or development to Comcast, including notice of the date and place of any negotiating sessions as they are planned or contemplated and permit Comcast to have a representative present at all negotiating sessions with such labor organization and at all meetings preparatory thereto (including making Comcast's representative a representative of its delegation if required by the labor organization), and (ii) not, without Comcast's written consent, enter into any Contract with such labor organization that binds or purports to bind Comcast or its Affiliates (including the Transferred Entities), including any successor clause or other clause that would have this purpose or effect. Except with respect to AT&T's NCE Agreement, AT&T and its Affiliates acknowledge and agree that Comcast and its Affiliates (including the Transferred Entities) have not agreed to be bound, and will not be bound, without an explicit assumption of such liability or responsibility by Comcast, by any 49

provision of any collective bargaining agreement or similar Contract with any labor organization to which AT&T or any of its Affiliates is or may become bound. 7.5.11. Nothing in this Section 7.5 or elsewhere in this Agreement shall be deemed to make any employee of AT&T, Comcast or any of their Affiliates a third party beneficiary of this Agreement. 7.5.12. The Parties agree to cooperate with each other and to exchange all information required to implement the provisions of this Section 7.5. 7.6. Leased Vehicles; Other Capital Leases. AT&T will pay the remaining balances on any leases for vehicles or capital leases that would be included in the AT&T Assets but for the effect of this Section 7.6, and will deliver title to such vehicles and other Tangible Personal Property included among the AT&T Assets, free and clear of all Liens (other than Permitted Liens), to the Transferred Entities immediately prior to the Closing. 7.7. Required Consents; Franchise Renewal. 7.7.1. Each Party will use its commercially reasonable efforts to (i) obtain in writing, as promptly as possible and at its expense, all of the Required Consents of such Party, other than consents in connection with multiple dwelling unit agreements, required to be obtained by such Party in connection with the transactions contemplated by this Agreement, and deliver to the other Parent copies of such Required Consents and such other consents, authorizations or approvals promptly after they are obtained by such Party, and (ii) give any required written notice in connection with the transactions; provided that such Party will afford the other Parent the opportunity to review, and comment on the form of letter or application proposed to request the Required Consent or form of written notice prior to delivery to the Person whose consent is sought or to whom such notification is required. All documents delivered or filed with any Governmental Authority or any Person by or on behalf of such Party pursuant to this Section 7.7.1, when so delivered or filed, will be correct, current and complete in all material respects. Each Party will cooperate with the other Parties to obtain all Required Consents and no Party shall intentionally take any action or steps that would prejudice or jeopardize the obtaining of any Required Consent. 7.7.2. AT&T and its Affiliates will not accept or agree or accede to any modifications or amendments to, or the imposition of any condition to the transfer of, any of the AT&T System Franchises, AT&T System Licenses or AT&T System Contracts that are not reasonably acceptable to Comcast. Notwithstanding the foregoing, Comcast and its Affiliates will cooperate with AT&T and its Affiliates, and AT&T and its Affiliates and Comcast and its Affiliates will use commercially reasonable efforts to complete, execute and deliver, or cause to be completed, executed and delivered, to the appropriate Governmental Authority, a FCC Form 394 to the extent not previously filed with respect to each System Franchise included among the AT&T Assets within thirty (30) days after the date of this Agreement. Without the prior consent of Comcast, AT&T and its Affiliates shall not agree with any Governmental Authority to extend or to toll the time limits applicable to such Governmental Authority's consideration of any FCC Form 394 filed with such Governmental Authority. 50

7.7.3. Notwithstanding the provisions of Sections 7.7.1 and 7.7.2, AT&T will not have any further obligation to obtain AT&T Required Consents: (a) with respect to license agreements relating to pole attachments where the licensing authority will not consent to an assignment or change of control of such license agreement but requires that the Transferred Entity enter into a new agreement with such licensing authority on terms that are not materially less favorable in the aggregate to the Transferred Entity, in which case the Transferred Entity shall use its commercially reasonable efforts to enter into such agreement, provided such agreement is reasonably acceptable to Comcast, prior to the Closing or as soon as practicable thereafter, and AT&T and its Existing Affiliates will cooperate with and assist the Transferred Entity in obtaining such agreements; (b) for any business radio license or any private operational fixed service ("POFS") microwave license which would reasonably be expected to be obtained within one hundred twenty (120) days after the Closing and so long as a conditional temporary authorization (for a business radio license) or a special temporary authorization (for a POFS microwave license) is obtained by the Transferred Entity under FCC rules with respect thereto; (c) with respect to Contracts evidencing AT&T Leased Property, if, with the consent of Comcast, AT&T causes the applicable Transferred Entity to obtain and make operational prior to the Closing substitute Leased Property that is, and that is leased on terms that are, reasonably satisfactory to Comcast; (d) with respect to Contracts evidencing leased AT&T Tangible Personal Property that is material to AT&T's Cable Business, if, with the consent of Comcast, AT&T causes the applicable Transferred Entity to obtain and make operational prior to the Closing substitute AT&T Tangible Personal Property that is reasonably satisfactory to Comcast. 7.7.4. (a) Upon the written request of Comcast, if and to the extent that any Required Consents have not been obtained on or prior to the Closing (whether or not any Party shall have waived satisfaction of the condition to the Closing set forth in Section 8.2.5 or Section 8.3.5), subsequent to the Closing, AT&T will continue to use commercially reasonable efforts to obtain in writing, as promptly as possible, such AT&T Required Consents and will deliver copies of the same, reasonably satisfactory in form and substance, to Comcast. The obligations set forth in this Section 7.7.4 will survive the Closing. (b) This Agreement shall not constitute an agreement to assign to any Transferred Entity in the Internal Restructuring any Asset or any claim or right or any benefit arising thereunder or resulting therefrom without the consent of a Third Party thereto if such assignment without such consent would constitute a breach or other contravention of such Asset or in any way adversely affect the rights of the Transferred Entity thereunder. If any AT&T Required Consent (except AT&T Required Consents for AT&T Systems Franchises), relating to the assignment of an AT&T Asset to a Transferred Entity shall not have been obtained prior to Closing, AT&T and Comcast will cooperate in a mutually agreeable arrangement under which, to the extent practicable and permitted by such agreement and applicable law, the Transferred Entity will obtain the benefits and be responsible for the obligations in accordance with this Agreement in respect of such AT&T Asset or any claim or right or any benefit arising thereunder the assignment of which without the consent of the Third Party thereto would constitute a breach or other contravention of such AT&T Asset or in any way adversely affect the rights of the Transferred Entity thereunder, including sub-contracting, sub-licensing, or sub-leasing to the Transferred Entity, or under which AT&T will enforce for the benefit of the Transferred Entity, with the Transferred Entity assuming AT&T's and its Affiliates' obligations, any and all rights of AT&T and its Affiliates against the Third Party in question. AT&T and its Affiliates will 51

promptly pay to the Transferred Entity, when received, all monies received by AT&T and its Affiliates in respect of any such AT&T Asset or any claim or right or any benefit arising thereunder and the Transferred Entity shall promptly pay or perform any obligations in respect of any such AT&T Asset. 7.7.5. AT&T and its Affiliates shall not be required to make any payment (other than customary filing and similar fees) to a Person from whom consent is sought in order to obtain such consent and Comcast shall not be obligated to reimburse AT&T or any of its Affiliates for any payment so made. 7.8. Title Commitments and Surveys. Comcast will have the option to obtain, at its own expense, (i) commitments of title insurance ("Title Commitments") issued by a nationally recognized title insurance company selected by Comcast (the "Title Company") and containing policy limits and other terms reasonably acceptable to Comcast, and photocopies of all recorded items described as exceptions therein committing to insure fee or leasehold title in the applicable Transferred Entity to each parcel of AT&T Owned Property or AT&T Leased Property owned by or to be transferred to such Transferred Entity under the Internal Restructuring, by American Land Title Association ("ALTA") (1992) owner's or lessee's policies of title insurance, and (ii) current ALTA as-built surveys of each such parcel as is necessary to obtain the title insurance to be issued pursuant to the Title Commitments with the standard printed exceptions relating to survey matters deleted (the "Surveys"), certified to Comcast and the Title Company issuing a Title Commitment. If Comcast notifies AT&T within twenty (20) days after the date of this Agreement or, if later, of its receipt of both the Title Commitments and the Surveys of any Lien (other than a Permitted Lien) or other matter affecting title to such AT&T Owned Property or AT&T Leased Property which prevents or materially interferes with (or presents a material risk of preventing or interfering with) the use of any such parcel for the purposes for which it is currently used or operated (each a "Title Defect"), AT&T will, at its own expense, exercise commercially reasonable efforts to remove or, with the consent of Comcast, cause the Title Company to commit to insure over, each such Title Defect prior to the Closing. 7.9. HSR Act Notification. If any event (including the passage of time) occurs which subjects the transactions contemplated by this Agreement to any further requirements under the HSR Act, then as promptly as practicable, Comcast and AT&T will each complete and file, or cause to be completed and filed, at its own cost and expense, any notification and report required to be filed under the HSR Act with respect to the transactions contemplated by this Agreement, and each such filing shall request early termination of the waiting period imposed by the HSR Act. The Parties shall use their respective commercially reasonable efforts to respond, as promptly as reasonably practicable, to any inquiries received from the Federal Trade Commission (the "FTC") and the Antitrust Division of the Department of Justice (the "Antitrust Division") for additional information or documentation, and to respond, as promptly as reasonably practicable, to all inquiries and requests received from any other Governmental Authority in connection with antitrust matters. The Parties shall use their respective commercially reasonable efforts to overcome any objections which may be raised by the FTC, the Antitrust Division or any other Governmental Authority having jurisdiction over antitrust matters. Each Party shall (i) promptly notify the other Party of any written communication to that Party from the FTC, the Antitrust Division, any State Attorney General or any other Governmental Authority and, subject to applicable law, permit the other Party to review in 52

advance any proposed written communication to any of the foregoing; (ii) not agree to participate in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning this Agreement or the transactions contemplated hereby unless it consults with the other Party in advance and, to the extent permitted by such Governmental Authority, gives the other Party the opportunity to attend and participate thereat; and (iii) furnish the other Party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their Affiliates and their respective representatives on the one hand, and any Government Authority or members or their respective staffs on the other hand, with respect to this Agreement and the transactions contemplated hereby. Notwithstanding the foregoing, Comcast and its Affiliates shall not be required to make any significant change in the operations or activities of their business (or any material assets employed therein) or the AT&T Cable Business if, Comcast determines in good faith that such change would be materially adverse to the operations or activities of the business (or any material assets employed therein) of Comcast or any of its Affiliates or any of the Transferred Entities, having significant assets, net worth or revenue. 7.10. Sales and Transfer Taxes. Comcast and AT&T shall each, respectively, pay one-half of (i) all Transfer Taxes arising from or payable by reason of the transfer of any of the AT&T Assets and (ii) all Transfer Taxes or assessments, and any transfer fees and similar assessments for or under AT&T Systems Franchises, AT&T Systems Licenses and AT&T Systems Contracts, arising from or payable by reason of the transfer of the AT&T Assets. Notwithstanding the foregoing, all Transfer Taxes or assessments, and transfer fees and similar assessments arising from or payable by reason of the Internal Restructuring will be borne by AT&T. 7.11. Programming. AT&T or its applicable Affiliate will execute and deliver letters substantially in the form attached as Exhibit 7.11 as may be reasonably requested by Comcast to Persons that are parties to AT&T's or its applicable Affiliate's programming agreements. 7.12. Retention of Books and Records. Following the Closing, AT&T and its Existing Affiliates shall give access to Comcast, its counsel, accountants and other authorized representatives during normal business hours to AT&T's and its Existing Affiliates' materials, books, records and documents which relate to the operations of AT&T's Cable Business prior to the Closing Time as may be reasonably necessary in connection with any legitimate purpose (including the preparation of tax reports and returns and the preparation of financial statements). Such access will be subject to the applicable document retention policies of AT&T and its Existing Affiliates (provided that AT&T and its Existing Affiliates will use commercially reasonable efforts (i) not to destroy any such records without first notifying Comcast and giving Comcast the opportunity to make copies and (ii) to obtain copies of, or provide Comcast and its representatives access to, any materials, books, records and documents that relate to the operations of AT&T's Cable Business prior to the Closing Time and that are held by an Affiliate of AT&T that is not then an Existing Affiliate of AT&T), shall be subject to reasonable advance written notice, will be conducted in a manner that is not disruptive of AT&T's and its Existing Affiliates' business and will be subject to any other reasonable limitations imposed by AT&T and its Existing Affiliates. Comcast shall have the right to make copies of such materials at its own expense. 53

7.13. Use of Name and Logo. For a period of one hundred eighty (180) days after the Closing, each Comcast Entity and each Transferred Entity will be granted a non-exclusive, non-transferable license to use the trademarks, trade names, service marks, service names, logos and similar proprietary rights of AT&T and its Existing Affiliates to the extent incorporated in or on the AT&T Assets Transferred at the Closing on a royalty-free basis, provided that each Comcast Entity and each Transferred Entity will exercise commercially reasonable efforts to remove all such names, marks, logos and similar proprietary rights of AT&T and its Affiliates (except to the extent otherwise permitted by AT&T and its Affiliates) from such AT&T Assets as soon as reasonably practicable, and in any event within one hundred eighty (180) days, following the Closing. Notwithstanding the foregoing, nothing in this Section 7.13 will require each Comcast Entity or any Transferred Entity to remove or discontinue using any such name or mark that is affixed to converters or other items already installed in or to be used in customer homes or properties and Transferred to each Comcast Entity as of the Closing, or as are already installed and used in a similar fashion as of the Closing making such removal or discontinuation impracticable. 7.14. Transitional Billing Services. AT&T and its Existing Affiliates will provide to the Transferred Entities, upon written request delivered a reasonable amount of time in advance, access to and the right to use its billing system computers, software and related fixed assets in connection with the Systems Transferred for a period of up to one hundred eighty (180) days following the Closing to allow for conversion of existing billing arrangements, including billing and related arrangements (such as refunds) regarding internet access and telephony services being provided to customers of a System on the Closing Date ("Transitional Billing Services"). Comcast will notify AT&T at least thirty (30) days prior to the Closing as to whether it desires the Transferred Entities to have Transitional Billing Services from AT&T and its Existing Affiliates. All Transitional Billing Services, if any, that are requested by Comcast will be provided on terms and conditions reasonably satisfactory to Comcast and AT&T; provided, however, that the amount to be paid by Comcast receiving Transitional Billing Services will not exceed the cost to AT&T and its Existing Affiliates of providing such Transitional Billing Services. AT&T and its Existing Affiliates will notify Comcast of the cost of providing such Transitional Billing Services within ten (10) Business Days after receiving Comcast's notice requesting the provision of such Transitional Billing Services. The Parties agree that the Parties' respective rights to receive Transitional Billing Services pursuant to this Section 7.14 have nominal value. 7.15. Confidentiality and Publicity. 7.15.1. Prior to the Closing, each Inspecting Party will keep confidential any non-public information that such Inspecting Party may obtain from the Disclosing Party in connection with this Agreement, and, following the Closing, each Inspecting Party will keep confidential any non-public information that such Inspecting Party may obtain from the Disclosing Party in connection with this Agreement unrelated to AT&T's Cable Business and the Systems Transferred by the Disclosing Party pursuant to this Agreement. Following the Closing, AT&T and its Affiliates will keep confidential any nonpublic information in the possession of such Persons related to AT&T's Cable Business or the AT&T Systems (and such Persons will be treated as an "Inspecting Party" and Comcast the "Disclosing Party" with respect to such information for purposes of this Section 7.15.1). Any information that a Person is required to 54

keep confidential pursuant to the foregoing sentences shall be referred to as "Confidential Information". Each Inspecting Party will not disclose any Confidential Information to any other Person (other than its directors, officers and employees and representatives of its advisers and lenders (collectively, "Representatives"), in each case, whose knowledge thereof is necessary in order to facilitate the consummation of the transactions contemplated hereby, in which event such Inspecting Party shall be responsible for any breach hereof by any such Person) or use such Confidential Information to the detriment of the Disclosing Party; provided that (i) such Inspecting Party may use and disclose any such Confidential Information once it has been publicly disclosed (other than by such Inspecting Party or its Representatives in breach of the obligations under this Section 7.15.1) or which, in the case of information provided by the Disclosing Party, has come into the possession of such Inspecting Party (other than from the Disclosing Party and other than from another Person in violation of any duty or obligation of confidentiality known to the Inspecting Party) and (ii) to the extent that such Inspecting Party may, in the opinion of its counsel, be compelled by Legal Requirements to disclose any of such Confidential Information, such Inspecting Party may disclose such Confidential Information if it uses all reasonable efforts, and affords the Disclosing Party the opportunity, to obtain an appropriate protective order or other satisfactory assurance of confidential treatment, for the Confidential Information compelled to be disclosed. In the event of termination of this Agreement, each Inspecting Party will cause to be delivered to the Disclosing Party, and retain no copies of, any documents, work papers and other materials obtained by such Inspecting Party or on its behalf from the other, whether so obtained before or after the execution hereof. 7.15.2. No Parent nor its Affiliates will issue any press releases or make any other public announcement concerning this Agreement and the transactions contemplated hereby, except as required by applicable Legal Requirements or by any national securities exchange or quotation system without the prior written consent and approval of the other Parent, which consent and approval may not be unreasonably withheld. 7.16. Bulk Transfer. AT&T waives compliance by Comcast and its Affiliates with Legal Requirements relating to bulk transfers applicable to the transactions contemplated hereby. 7.17. Lien Searches. AT&T will, at its expense, obtain and disclose to Comcast the results of a Lien search conducted by a professional search company of records in the offices of the secretaries of state in each state and county clerks in each county where there exist any of the AT&T Owned Property or AT&T Tangible Personal Property included among the AT&T Assets, and in the state and county where each Transferred Entity's and Retained Entity's principal offices are located, including copies of all financing statements or similar notices or filings (and any continuation statements) discovered by such search company. 7.18. Reasonable Best Efforts; Further Assurances. Subject to the terms and conditions of this Agreement, each Party will use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or desirable to satisfy all conditions and to consummate the transactions contemplated by this Agreement. AT&T and Comcast agree to cause each of its Affiliates party hereto to perform, pay and satisfy all of such Affiliate's obligations under this Agreement. At or after the Closing, AT&T and Comcast and their Affiliates party hereto at the request of the other Parent, will promptly execute and deliver, or cause to be executed and delivered, to the other Parent all such documents and instruments, in 55

addition to those otherwise required by this Agreement, in form and substance reasonably satisfactory to the other Parent as the other Parent may reasonably request in order to carry out or evidence the terms of this Agreement or to collect any accounts receivable or other claims included in the AT&T Assets Transferred to Comcast or its Affiliates. 7.19. Cooperation as to Rates. 7.19.1. AT&T and its Affiliates will cooperate with and assist Comcast by providing, upon reasonable request, all information in their possession (and not previously made available to Comcast) relating directly to the rates set forth on Schedule 6.17, as applicable, or on any of FCC Form 1200, 1205, 1210, 1220, 1225, 1235 or 1240 or any other FCC Form filed with respect to the Systems that Comcast may reasonably require to justify such rates in response to any inquiry, order or requirements of any Governmental Authority. 7.19.2. Prior to the Closing, neither AT&T nor its Affiliates shall settle or permit to be settled any rate (including late fees) proceeding with respect to its Systems without consulting with Comcast; provided that AT&T and its Affiliates shall not agree to any forward-looking rate adjustment with respect to the Systems without the prior written consent of Comcast. 7.19.3. After the Closing, AT&T and its Existing Affiliates will be responsible for and follow to conclusion any rate order of any Governmental Authority or proceeding with respect to rates (including late fees) of any of its Systems charged by the Retained Entities or Transferred Entities immediately prior to the Closing; provided, however, that with respect to the Systems AT&T and its Affiliates shall not: (i) agree to any refund of past overcharges; (ii) submit any refund plan to a Governmental Authority; (iii) appeal or take any other action with regard to such proceeding, in each case without consulting with Comcast; or (iv) agree to any forward-looking rate adjustment without the prior written consent of Comcast. AT&T and its Affiliates will cooperate with and assist Comcast by providing, upon reasonable request, all information in their possession (and not previously made available to Comcast) that Comcast may reasonably require to justify rates, charges, late fees and similar payments in response to any inquiry, order or requirements of any Governmental Agency. 7.19.4. If, following the Closing, any System is required pursuant to any Legal Requirement, settlement or otherwise to refund to subscribers any payments, in whole or in part, made by such subscribers prior to the Closing, including fees for cable television service, equipment charges, late fees and similar payments, then, at the election of Comcast: (i) AT&T must fulfill such refund obligation through a one time cash payment to subscribers, in which case AT&T shall provide funds for such payment to Comcast, Comcast shall cooperate with AT&T or implement and administer such refund payment through Comcast's billing system, and AT&T shall reimburse Comcast for all reasonable expenses incurred by Comcast and its Affiliates (including the Transferred Entities) in connection therewith; or (ii) Comcast may fulfill such refund obligation through a cash payment, credit or in-kind or other form of consideration, at its discretion and subject to any required approval by a Governmental Authority, and AT&T shall reimburse Comcast in the amount of any payment or in the amount of the cost to Comcast or its Affiliates of any credit or in-kind or other form of consideration and all reasonable expenses incurred by Comcast or its Affiliates in connection therewith. Without limiting the foregoing, 56

Comcast will provide AT&T with all information in Comcast's and its Affiliates (including the Transferred Entities) possession that is reasonably required by AT&T in connection with such reimbursement. 7.19.5. If Comcast or any of its Affiliates is permitted following the Closing to pass through to subscribers of Systems Transferred at Closing, the amount of any "franchise fees on franchise fees" paid by AT&T and its Affiliates (including the Transferred Entities) to the appropriate local franchising authority with respect to the period prior to the Closing, Comcast agrees that it will collect, for the benefit of AT&T, such amounts specified no later than the Six-Month Date as paid by AT&T and, except as specified below, will promptly remit such amounts to AT&T; provided, however, that, if Comcast is provided by counsel with an opinion that the pass through to subscribers of such fees under the rules and regulations of the FCC and the Communications Act (either with respect to the cable industry as a whole or the particular Systems in question) is subject to administrative or judicial review, then Comcast shall not remit the fees to AT&T but shall hold such fees until the final resolution of such administrative or judicial proceedings. After such final resolution, Comcast will remit to AT&T as appropriate, such fees. AT&T agrees to provide Comcast with such documentation as necessary to demonstrate the payment of the "franchise fees on franchise fees" and to enable Comcast to collect the pass through amounts from subscribers. No amount collectible for the benefit of AT&T under this Section 7.19.5 will be taken into account in determining the Working Capital Adjustment Amount. 7.20. Cooperation as to Late Fee Cases. 7.20.1. (a) Notwithstanding anything to the contrary in this Agreement, and without limiting any other provisions of this Agreement, from and after Closing, Comcast will cause the Transferred Entities to comply with their obligations under paragraph 18 of the Settlement Agreement and Release entered into effective as of March 17, 2000, a final executed copy of which has been provided to Comcast (the "Settlement Agreement"), to the extent such obligations relate to Systems that are "Class Systems" within the meaning of the Settlement Agreement and to litigation that is covered by the Settlement Agreement. AT&T will reimburse the Transferred Entities for any payments made by them to subscribers in accordance with the terms of the Settlement Agreement, for any direct out-of-pocket costs to them of providing any credit or in-kind or other form of consideration to subscribers in accordance with the terms of the Settlement Agreement and for their reasonable expenses incurred in connection with fulfilling their obligations under this Section. Comcast will keep the Retained Entities and their Affiliates fully informed regarding the implementation of Section 18 of the Settlement Agreement insofar as it relates to the Systems, will provide the Retained Entities and their Affiliates with such information as they may reasonably request in connection therewith, and will be subject to the general direction of the Retained Entities in connection therewith. Comcast acknowledges that it has received a copy of the final, executed Settlement Agreement. (b) In regard to Baltimore, Maryland, if necessary, Comcast will similarly assist and cooperate in connection with the Order Regarding Final Implementation of Final Judgment entered on January 20, 2000 (regarding Baltimore), and regarding the state of Maryland, excluding Baltimore, and Holdren v. TCI Cablevision of Maryland, Inc., et al., pending in the Circuit Court of Worcester County, Maryland. 57

The provisions of paragraph (a) above (including as to reimbursement of payments, costs and expenses) will apply mutatis mutandis to any settlement agreement entered into with respect to any matter addressed in this paragraph (b); provided that as to any such matter, neither AT&T nor any of its Affiliates will enter into any settlement agreement that would govern the operation of the Systems after the Closing, unless Comcast has given its prior written consent to such settlement agreement. 7.21. Distant Broadcast Signals. Unless otherwise restricted or prohibited by any Governmental Authority, applicable Legal Requirements or Contract, AT&T and its Existing Affiliates will, if requested by Comcast, delete, prior to the Closing, any distant broadcast signals which Comcast determines will result in unacceptable liability on the part of Comcast for copyright payments with respect to continued carriage of such signals after the Closing. Comcast will use reasonable efforts to deliver notice of the requested deletions to AT&T at least sixty (60) days prior to the Closing. 7.22. Offers. AT&T and its Affiliates party hereto (and its and their directors, officers, employees, representatives and agents) shall not, directly or indirectly, (i) offer AT&T's Cable Business or Systems for sale, (ii) solicit, encourage or entertain offers for AT&T's Cable Business or such Systems, (iii) initiate negotiations or discussions for the sale of AT&T's Cable Business or such Systems or (iv) make information about AT&T's Cable Business or such Systems available to any Third Party in connection with the possible sale of AT&T's Cable Business or such Systems prior to the Closing Date or the date this Agreement is terminated in accordance with its terms. The foregoing limitations relate specifically to the AT&T Systems and AT&T's Cable Business and shall not limit in any way AT&T's ability to engage in transactions relating to AT&T or AT&T Broadband generally that do not have a Material Adverse Effect or materially adversely effect the consummation of the transactions contemplated hereby. 7.23. @Home. The applicable Transferred Entity will assume, from and after the Closing, all rights and obligations of the AT&T Cable Subsidiaries under the @Home Distribution Agreement between Intermedia Partners and @Home Corporation dated January 1, 1999 to the extent such agreement applies to the Nashville System, other than warrants relating to the Upgraded Homes Test (as set forth in the At Home Corporation Warrant Term Sheet dated January 1, 1999) which will remain with AT&T. 7.24. Cooperation with Financial Statements. AT&T agrees to use reasonable efforts to provide Comcast with information about the AT&T Systems, to the extent needed (but only to the extent needed) for preparation of financial statements to be included in Comcast's filings with Securities and Exchange Commission under federal securities laws; provided that Comcast shall bear all costs (including any internal cost) associated with the provision of such information. 7.25. Accounts Payable and Franchise Fees. (a) AT&T shall pay in the ordinary course of business, consistent with past practices, all accounts payables and franchise fees incurred in or attributable to periods or portions thereof ending on or prior to the Closing Time with respect to the Systems that it Transfers (which accounts payables and franchise fees will not 58

be Transferred with the Systems), subject to contesting any payments pursuant to a bona fide dispute. (b) All long-term debt of any Transferred Entity and intercompany payables owed by or intercompany receivables owed to any Transferred Entity will be paid or otherwise assumed by a Retained Entity prior to the Closing Time. 7.26. Termination of Certain Affiliate Contracts. All contracts listed on Schedule 7.26 will be terminated prior to Closing. 7.27. Capital Management Committee. AT&T and Comcast agree that a capital management committee will be formed to efficiently and effectively monitor capital spending in the affected Systems and to address capital budget issues as they arise. 7.28. Reorganization. 7.28.1. From and after the Closing Date until the date that is two years after the Closing Date, (i) neither Comcast nor any of its Affiliates shall sell, exchange or otherwise dispose of any of the AT&T Cable Subsidiaries shares or any of the Assets of the Systems held by any of the Transferred Entities as of the Closing Date in a manner that would cause the Reorganization to fail to be tax-free under Sections 355(a) and (c); (ii) neither Comcast nor any of its Affiliates shall cause the liquidation or merger of any of the AT&T Cable Subsidiaries in a manner that would cause the Reorganization to fail to be tax-free under Section 355(a) and (c); (iii) neither Comcast nor any of its Affiliates shall take or cause to be taken, or fail to take or fail to cause to be taken, any action which would cause any of the AT&T Cable Subsidiaries to fail to be engaged in the active conduct of a trade or business within the meaning of Code Section 355(b)(1)(A) in connection with the Reorganization; and (iv) neither Comcast nor any of its Affiliates shall enter into any agreement, option, understanding or arrangement, or initiate or conduct any negotiations, in each case in connection with any of the actions prohibited by clauses (i), (ii) and (iii) of this Section 7.28.1. 7.28.2. Neither AT&T nor any of its Affiliates shall take or cause to be taken, or fail to take or fail to cause to be taken, any action subsequent to the date hereof (including, for the avoidance of doubt, after the Closing Date), that would cause the representation in Section 6.5.1 or 6.5.3 to fail to be true if made at the time of such action or inaction. 7.28.3. Unless otherwise required by a "determination" within the meaning of Code Section 1313(a) (a "Determination"), AT&T and Comcast shall report (and, shall take no action or position inconsistent with the treatment of) the Reorganization for income Tax purposes as tax-free to Comcast and to AT&T under Code Sections 355(a) (as to Comcast) and 355(c) (as to AT&T) (other than with respect to income or gain, if any, required to be taken into account by AT&T or any Subsidiary of AT&T under Treasury Regulations Sections 1.1502-13 or 1.1502-19 as a result of the Reorganization). 7.29. Tax Sharing Agreements. Any and all existing Tax Sharing Agreements to which a Transferred Entity is a party shall be terminated with respect to such Transferred Entity as of the Closing Date. After the Closing Date, none of the Transferred Entities shall have any further rights or liabilities thereunder. 59

7.30. Tax Matters. 7.30.1. Filing of Tax Returns. (a) AT&T shall be responsible for the preparation and filing of all Tax Returns of the Transferred Entities for all taxable periods that end as to the Transferred Entities on or before the Closing Date and all Consolidated Tax Returns, including Tax Returns of the Transferred Entities for taxable periods that end as to the Transferred Entities on or before the Closing Date but are due after the Closing Date, and AT&T shall be responsible for the contents of such Tax Returns and for the payment of all Taxes due with respect thereto (subject to indemnification by Comcast to the extent provided in Section 7.30.2) AT&T shall file or cause to be filed all such Tax Returns when due, and shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. All such Tax Returns will be filed when due in accordance with all applicable laws and as of the time of filing, will be true and complete in all material respects. AT&T shall include the Transferred Entities in its Consolidated Tax Return and in any Combined Tax Return through the close of business on the Closing Date. AT&T shall have the sole authority to deal with any matters (including any Tax Proceeding) relating to any Consolidated Tax Returns and any Tax Returns of the Transferred Entities for taxable periods ending as to the Transferred Entities on or prior to the Closing Date, except that AT&T shall not take any position, make any election or adopt any method that would reasonably be expected to adversely affect any Transferred Entity or Comcast or any of its Affiliates with respect to the Post-Closing Tax Period and that is inconsistent with positions taken, elections made or methods used in preparing similar Tax Returns for prior periods, unless otherwise required by applicable law or pursuant to a Determination and (ii) Comcast may, at its option, cause each Transferred Entity to elect, where permitted by applicable law, to carry forward any tax asset that would, absent such election, be carried back to a Pre-Closing Tax Period in which such Transferred Entity was included in a consolidated, combined or unitary Tax Return filed by AT&T or any of its Affiliates. Comcast shall, and shall cause its Affiliates and the Transferred Entities to, facilitate the exercise of AT&T's rights pursuant to the immediately preceding sentence, including by providing AT&T or its designees with any reasonably requested power of attorney with respect to such Tax Returns or Tax Proceedings. (b) Comcast shall be responsible for the preparation and filing of all Tax Returns of the Transferred Entities for all taxable periods that end as to the Transferred Entities after the Closing Date (including Straddle Periods), and Comcast shall be responsible for the contents of such Tax Returns and the payment of all Taxes due with respect thereto (subject to indemnification by AT&T to the extent provided in Section 7.30.2); provided, however, that with respect to any Straddle Period, Comcast shall be responsible for Taxes for the portion of such Straddle Period that ends on the Closing Date only to the extent that either such Taxes are taken into account as current liabilities in computing the Working Capital Adjustment Amount pursuant to Section 3.2 or Comcast is obligated to indemnify AT&T pursuant to Section 7.30.2. Comcast shall file or cause to be filed all such Straddle Period Tax Returns when due, and shall remit or cause to be remitted any Taxes due in respect of such returns. All such Straddle Period Tax Returns shall be prepared and filed in a manner consistent with past practice of the Transferred Entities (and the Retained Entities with respect to the Systems) and consistent with the manner in which Tax Returns of the Transferred Entities are prepared and filed by AT&T pursuant to this Section 7.30.1, and, on such Straddle Period Tax Returns, no position shall be taken, election made or method adopted that is inconsistent with positions taken, elections made or methods used in preparing similar Tax Returns for prior periods unless otherwise required by 60

applicable law or pursuant to a Determination and except for manners, positions, elections and methods that, in the case of any Straddle Period Tax Return that includes any Transferred Entity, on the one hand, and Comcast or any Subsidiary of Comcast other than a Transferred Entity, on the other hand (a "Comcast Consolidated Tax Return"), would be applicable to entities other than the Transferred Entities and, in the case of any other Straddle Period Tax Returns, are required to be filed in conformity with such Comcast Consolidated Tax Returns. Except as provided in Section 7.30.4, Comcast shall have the sole authority to deal with any matters (including any Tax Proceeding) relating to Tax Returns of the Transferred Entities for taxable periods ending as to the Transferred Entities after the Closing Date. (c) Except to the extent taken into account in computing the Working Capital Adjustment Amount pursuant to Section 3.2, Comcast shall promptly pay or cause to be paid to AT&T all refunds of Taxes and interest thereon received by Comcast or any Affiliate of Comcast attributable to Taxes paid by AT&T or any Transferred Entity with respect to any taxable period of any Transferred Entity ending on or before the Closing Date or with respect to the portion of any Straddle Period ending on or prior to the Closing Date. AT&T shall promptly pay or cause to be paid to Comcast all refunds of Taxes and interest thereon received by AT&T or any Affiliate of AT&T attributable to Taxes paid by Comcast or the Transferred Entities with respect to any taxable period ending after the Closing Date. (d) Following the Closing Date, Comcast shall cause the Transferred Entities to empower, by appropriate powers of attorney, if necessary, one or more designees of AT&T to sign all Tax Returns for any taxable period of any Transferred Entity that AT&T is required to file or cause to be filed pursuant to this Section 7.30.1. 7.30.2. Payment of Taxes; Tax Indemnification. (a) AT&T shall be liable for, and shall hold Comcast, the Transferred Entities and each other Affiliate of Comcast (each, a "Comcast Tax Indemnitee", and, collectively, the "Comcast Tax Indemnitees") harmless from and against, (a) any and all Taxes due and payable with respect to the Systems, and (b) any and all Taxes of the Transferred Entities, in the case of clauses (a) and (b) above, for any taxable period ending on or prior to the Closing Date and, with respect to any Straddle Period, for the portion of such period ending on and including the Closing Date (other than, in the case of clauses (a) and (b) above, any Taxes taken into account as Current Liabilities in calculating Working Capital or the Working Capital Adjustment, but only to the extent so taken into account, and any and all Taxes resulting from any acts of Comcast or any of its Subsidiaries or Affiliates, or which Comcast or any of its Affiliates causes any of the Transferred Entities to take, occurring on the Closing Date and not in the ordinary course of business after the Closing Time) (collectively, "Pre-Closing Taxes") (c) any and all Taxes described in clause (ii) or (iii) of the definition of Tax and (d) any and all Taxes of any of the Comcast Tax Indemnitees arising out of or resulting from an AT&T Tax Breach ("Comcast Taxes") and any and all Losses arising out of or incident to the imposition, assessment or assertion of any Tax described in (a), (b), (c) or (d); provided, however, that AT&T shall not be liable for, and shall not hold the Comcast Tax Indemnitees harmless from and against, any Pre-Closing Taxes or Comcast Taxes resulting from a breach by Comcast or any of its Affiliates of any representation contained in Section 5.5 or any covenant contained in Section 7.28 (a "Comcast Tax Breach"). 61

(b) Comcast shall be liable for, and shall hold AT&T, each Retained Entity and each other Affiliate of AT&T (each, an "AT&T Tax Indemnitee," and, collectively, the "AT&T Tax Indemnitees") harmless from and against, (a) any and all Taxes due and payable with respect to the Systems other than Pre-Closing Taxes, (b) any and all Taxes of the Transferred Entities other than Pre-Closing Taxes, (c) any Taxes taken into account as Current Liabilities in calculating Working Capital or the Working Capital Adjustment, but only to the extent so taken into account, and (d) any Taxes resulting from any acts of Comcast or any of its Subsidiaries or Affiliates, or which Comcast or any of its Affiliates causes any of the Transferred Entities to take, occurring on the Closing Date and not in the ordinary course of business after the Closing Time and any and all Losses arising out of or incident to the imposition, assessment or assertion of any Tax described in (a), (b), (c) or (d); provided, however, that Comcast shall not be liable for, and shall not hold the AT&T Tax Indemnitees harmless from and against any Taxes described in clause (a), (b), (c) or (d) resulting from a breach by AT&T or any of its Affiliates of any representation contained in Section 6.5 or Section 6.15 or any covenant contained in Section 7.2.16, 7.2.17, 7.28 or 7.29 (an "AT&T Tax Breach"). (c) AT&T shall be liable for, and shall hold the Comcast Tax Indemnitees harmless from and against, any and all Taxes of the Retained Entities, other than any such Taxes resulting from a Comcast Tax Breach. (d) Comcast shall be liable for, and shall hold the AT&T Tax Indemnitees harmless from and against, any Taxes resulting from a Comcast Tax Breach; provided that if the Comcast Tax Breach results from a breach of the representation contained in Section 5.5.1(b) without a breach of the representation contained in Section 5.5.1(a), Comcast shall be liable for 50% of any Taxes of all AT&T Tax Indemnitees imposed by reason of the application of Code Section 355(d) resulting from such breach; and provided further that Comcast shall not have any liability under this sentence in the event that the Reorganization does not qualify as tax-free under Code Section 355(a) and such failure is not solely the result of a breach by Comcast of its representations contained in Sections 5.5.2, 5.5.3 or 5.5.4. (e) For purposes of this Section 7.30, in the case of any Taxes that are imposed on a periodic basis and are payable for a Tax period that includes (but does not end on) the Closing Date, the portion of such Tax related to the portion of such Tax period ending on and including the Closing Date shall (i) in the case of any Taxes other than gross receipts, sales or use Taxes and Taxes based upon or related to income, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the Tax period ending on and including the Closing Date and the denominator of which is the number of days in the entire Tax period, and (ii) in the case of any Tax based upon or related to income and any gross receipts, sales or use Tax, be deemed equal to the amount which would be payable if the relevant Tax period ended on and included the Closing Date. For the avoidance of doubt, for purposes of this Section 7.30, the taxable year of each entity that is a partnership or "flowthrough" entity, shall be treated as if it ended at the close of business on the Closing Date and Taxes attributable to the income and gain of such entities through the close of business on the Closing Date shall be treated as Pre-Closing Tax Period Taxes. All determinations necessary to give effect to the allocation set forth in the foregoing clause (ii) shall be made in a manner consistent with prior practice of the Transferred Entities. 62

(f) Comcast shall use commercially reasonable efforts to submit to AT&T not later than sixty (60) days prior to the due date (including extensions) for filing such Tax Return, and shall submit to AT&T not later than thirty (30) days prior to the due date (including extensions) for filing such Tax Return, a copy (in the form proposed to be filed in all material respects) of any Tax Return required to be filed by it pursuant to this Section 7.30 for any Straddle Period (and a calculation of the amount of Tax, if any, in connection with such Tax Return, for which Comcast has determined AT&T is responsible) to AT&T for AT&T's review and consent, which consent shall not be unreasonably withheld. AT&T shall provide any comments on such Tax Return and calculation to Comcast within twenty (20) days of receipt of such Tax Return. Comcast shall file such Tax Return in a manner that reflects any good faith comments of AT&T, and shall provide AT&T with a copy of such filed Tax Return promptly after such Tax Return is filed; provided, however, that if Comcast disagrees in good faith with any such comments, such disagreement shall be resolved expeditiously by AT&T and Comcast, or, failing that, by a neutral arbitrator, mutually selected by the Parties, but if such disagreement has not been resolved before the due date (including extensions) for filing such Tax Return, then Comcast may file such Tax Return in a manner that Comcast, in its reasonable determination, deems appropriate and, following the final decision of such arbitrator, Comcast shall file an amended Tax Return to the extent necessary to reflect such final decision. If the amount of Taxes with respect to such Tax Return taken into account as liabilities in computing Working Capital or the Working Capital Adjustment Amount (plus, if applicable, any estimated Tax payments made by AT&T with respect to the portion of such Straddle Period ending on the Closing Date if Comcast is entitled to a credit for such estimated Tax payments on the respective Tax Return when such Tax Return is filed and such estimated Tax payments were not taken into account in computing Working Capital or the Working Capital Adjustment ("AT&T Credited Estimated Tax Payments")) is less than the amount of such Taxes with respect to such Tax Return as so filed (or, if applicable, with respect to the amended return filed in accordance with the decision of the arbitrator) payable for the portion of the respective Straddle Period ending on and including the Closing Date, then AT&T shall pay such shortfall to Comcast at least one (1) day prior to the due date (including extensions) for filing the respective Tax Return. If the amount of Taxes with respect to such Tax Return taken into account as Current Liabilities in computing Working Capital or the Working Capital Adjustment plus any AT&T Credited Estimated Tax Payments is greater than the amount of such Taxes with respect to such Tax Return as so filed payable for the portion of the respective Straddle Period ending on and including the Closing Date, then Comcast shall pay such excess (but not in excess of the Working Capital Adjustment therefor) to AT&T within five (5) days after filing the respective Tax Return. In the event the arbitration procedure described in this Section 7.30.2(f) applies and payment is required to be made hereunder after the due date for filing such Tax Return, then payment shall be made within thirty (30) days following the date of the decision of the arbitrator, with interest pursuant to Section 7.30.2(i) from the due date for such Tax Return. (g) Each of Comcast and AT&T shall promptly deliver to the other party any notice (or the relevant portion thereof) from any Tax authority received by it or any of its Affiliates relating to Taxes for which the other party is or may be liable pursuant to this Agreement. (h) Except as otherwise provided in this Section 7.30.2, not later than 30 days after receipt by Comcast or AT&T, as the case may be (the "Tax Indemnifying Party"), of 63

written notice from AT&T or Comcast, as the case may be (the "Tax Indemnified Party"), stating that any Tax, loss or other amount (a "Tax Indemnified Loss") for which the Tax Indemnifying Party is liable pursuant to this Section 7.30.2 has been or will be incurred by a Comcast Tax Indemnitee or an AT&T Tax Indemnitee, as the case may be (the "Tax Indemnitee"), and the amount thereof and of the indemnity payment requested, the Tax Indemnifying Party shall discharge its obligation to indemnify such Tax Indemnitee against such Tax Indemnified Loss by paying to such Tax Indemnitee an amount equal to the amount of the Tax Indemnified Loss. Notwithstanding the foregoing, if the Tax Indemnified Party provides the Tax Indemnifying Party with written notice of a Tax Indemnified Loss at least 30 days prior to the date on which the relevant Tax Indemnified Loss is required to be paid by the Tax Indemnitee, within that 30-day period the Tax Indemnifying Party shall discharge its obligation to indemnify such Tax Indemnitee against such Tax Indemnified Loss by making payments to the relevant Governmental Authority or such Tax Indemnitee, as directed by the Tax Indemnified Party, in an aggregate amount equal to the amount of such Tax Indemnified Loss. The payment by such Tax Indemnitee of any Tax Indemnified Loss shall not relieve the Tax Indemnifying Party of its obligation under this Section 7.30.2(h). Disputes arising under this Section 7.30.2(h) and not resolved by mutual agreement as stated therein shall be resolved by a neutral arbitrator, mutually selected by the Parties, within five days of the date on which the need to choose such arbitrator arises. Such arbitrator shall resolve any disputed items within 30 days of having the item referred to it pursuant to such procedures as it may require. The costs, fees and expenses of such arbitrator shall be borne equally by Comcast and AT&T. (i) If any amount payable hereunder is not paid when due, such amount shall bear interest from the date such payment is due to the date payment is made at the "underpayment rate" set forth in Code Section 6621. (j) The representations and warranties contained in Sections 5.5, 6.5 and 6.15 as well as the obligations pursuant to Sections 7.2.16, 7.2.17, 7.28, 7.29 and this Section 7.30 shall survive for the full period of all applicable statutes of limitations (giving effect to any waiver, mitigation or extension thereof). 7.30.3. Cooperation on Tax Matters. (a) AT&T and Comcast shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Section 7.30 and any Tax Proceeding. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. AT&T and Comcast agree (a) to retain all books and records with respect to Tax matters pertinent to the Transferred Entities relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by AT&T or Comcast, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (b) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, AT&T or Comcast, as the case may be, shall allow the other party to take possession of such books and records to the extent they would otherwise be destroyed or discarded. 64

(b) AT&T and Comcast further agree, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated hereby. 7.30.4. Tax Audits. (a) In the case of a Tax Proceeding relating to a Straddle Period (a "Straddle Period Tax Proceeding"), except in the case of a Reorganization Tax Proceeding, (i) Comcast shall control such Straddle Period Tax Proceeding if the claims for which Comcast is responsible exceed the claims for which AT&T is responsible and AT&T shall control such Straddle Period Tax Proceeding if the claims for which AT&T is responsible exceed the claims for which Comcast is responsible (Comcast or AT&T respectively, the "Controlling Party," and AT&T or Comcast, respectively, the "Noncontrolling Party"), (ii) the Controlling Party shall provide the Noncontrolling Party with a timely and reasonably detailed account of each stage of such Straddle Period Tax Proceeding and a copy of all documents (or portions thereof) relating to such Straddle Period Tax Proceeding which are relevant to any Tax for which the Noncontrolling Party may be required to indemnify the Controlling Party or any Affiliate of the Controlling Party or may otherwise be liable, (iii) the Controlling Party shall consult with the Noncontrolling Party before taking any significant action in connection with such Straddle Period Tax Proceeding that might adversely affect the Noncontrolling Party and shall consult with the Noncontrolling Party with respect to any written submissions in connection with such Straddle Period Tax Proceeding which are relevant to any Tax for which the Noncontrolling Party may be required to indemnify the Controlling Party or any Affiliate of the Controlling Party or may otherwise be liable, (iv) the Controlling Party shall defend such Straddle Period Tax Proceeding in good faith and diligently as if the taxpayer whose Tax Return is at issue were the only party in interest in connection with such Straddle Period Tax Proceeding, and, before any court, vigorously and with a view to the merits, (v) the Noncontrolling Party shall have the right to participate in any conference with any Tax authority regarding any Tax for which the Noncontrolling Party may be required to indemnify the Controlling Party or any Affiliate of the Controlling Party or may otherwise be liable, (vi) the Noncontrolling Party shall facilitate the Controlling Party's exercise of control over such Straddle Period Tax Proceeding, including by delivery of any reasonably requested powers of attorney with respect to such a Straddle Period Tax Proceeding, and shall not impede the Controlling Party's exercise of control over such Straddle Period Tax Proceeding, and (vii) the Controlling Party shall not settle, compromise or abandon any such Straddle Period Tax Proceeding without obtaining the prior written consent, which consent shall not be unreasonably withheld, of the Noncontrolling Party. In the event that the Noncontrolling Party reasonably withholds consent pursuant to clause (vii) above, the Noncontrolling Party shall be entitled to assume the defense of the Straddle Period Tax Proceeding; provided that the Controlling Party's liability in connection with the Straddle Period Tax Proceeding shall be limited to the amount such liability would have been under the proposed settlement. (b) In the case of a Tax Proceeding or portion thereof relating to the treatment of the Reorganization (such Tax Proceeding or portion thereof, a "Reorganization Tax Proceeding") as tax-free to Comcast and/or AT&T under Code Section 355(a) (as to Comcast) and Section 355(c) (as to AT&T), (i) the taxpayer shall provide the other party with a timely and reasonably detailed account of each stage of such Reorganization Tax Proceeding and a copy of all documents (or portions thereof) relating to such Reorganization Tax Proceeding, (ii) the 65

taxpayer shall consult with the other party before taking any significant action in connection with such Reorganization Tax Proceeding that might adversely affect the other party and shall consult with the other party with respect to any written submissions in connection with such Reorganization Tax Proceeding, (iii) the other party shall have the right to participate as an observer in the portion of any conference with any Tax authority regarding the Reorganization Tax Proceeding, and (iv) the taxpayer shall have the power to settle, compromise or abandon any such Reorganization Tax Proceeding; provided, however that if the other party refuses to consent to such settlement, compromise or abandonment, then a neutral arbitrator mutually selected by AT&T and Comcast shall determine the extent, if any, to which such settlement, compromise or abandonment resulted in a Tax liability related to the Reorganization in excess of the amount of any Tax liability related to the Reorganization for which a court would have held the taxpayer liable on the merits, and the other party's obligation to indemnify the taxpayer shall be reduced to the extent of such excess. Notwithstanding the foregoing, the other party shall be entitled to assume the defense of any claim (or any theory of liability underlying such claim) with respect to such Reorganization Tax Proceeding, provided that the other party admits in writing its liability to the taxpayer for any amounts arising in connection with such claim or theory and releases the taxpayer from an indemnity obligation arising in connection with such claim or theory. In the event that the other party assumes the defense of such Reorganization Tax Proceeding, the taxpayer shall be entitled to the rights of the other party as described in clauses (i), (ii) and (iii) of this Section 7.30.4 as if the other party were the taxpayer in such clauses. (c) In the case of a Tax Proceeding other than a Straddle Period Tax Proceeding or Reorganization Tax Proceeding (a "Separate Tax Proceeding"), the taxpayer shall not settle, compromise or abandon any such Separate Tax Proceeding without obtaining the prior written consent, which consent shall not be unreasonably withheld, of the other party if such settlement, compromise or abandonment would adversely affect the liability for Taxes (including, without limitation, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of loss of credits) of the other party, any of its Affiliates, or if Comcast is the other party, the Transferred Entities, for (i) the Pre-Closing Tax Period, if AT&T or any of its Affiliates is the other party, or (ii) the Post-Closing Tax Period, if Comcast or any of its Affiliates is the other party. If the taxpayer settles, compromises or abandons such Separate Tax Proceeding without obtaining such consent, it shall be liable for and hold the other party, its Affiliates and, if Comcast is the other party, the Transferred Entities harmless from and against any such adverse effect. The taxpayer may settle, compromise or abandon any such Separate Tax Proceeding without obtaining such prior written consent if it agrees in writing prior to such settlement, compromise or abandonment to be liable for and to hold the other party, its Affiliates and, if Comcast is the other party, the Transferred Entities, harmless from and against any such adverse effect. 7.31. Adjustment Event. (a) In the event that, after June 30, 1999 and prior to the date of Closing, (i) AT&T shall set a record date that is prior to the Closing for the issuance of any shares of AT&T Common Stock (or shares of a stock that is treated as capital stock of AT&T) ("Tracking Shares") as a stock dividend or 66

distribution to the holders of AT&T Shares on a tax-free basis (a "Distribution"), the Comcast Entities shall deliver hereunder the Tracking Shares so issued along with the underlying AT&T Shares, and no adjustment shall be made to the Agreed Share Value; (ii) AT&T shall set a record date that is prior to the Closing for the issuance of any other dividend or distribution to holders of AT&T Shares (other than normal quarterly cash dividends as the same may be adjusted from time to time), the Comcast Entities shall deliver hereunder only the underlying AT&T Shares (and not the distributed property), and the Agreed Share Value in respect of any AT&T Shares owned by Comcast or its Affiliates on or before the record date for such dividend or distribution shall be appropriately adjusted; (iii) AT&T Shares are changed on a tax-free basis (by merger or otherwise) into other securities or property, the Comcast Entities shall deliver hereunder, in lieu of the AT&T Shares, the kind and amount of securities or property that it received in respect to such AT&T Shares (the "New Consideration"), unless such delivery would create a substantial risk that the Reorganization would fail to be tax-free under Code Sections 355(a) and (c), and the New Consideration will be valued at the Agreed Share Value of the share for which it was received; provided that if a portion of the New Consideration is received by Comcast on a tax-free basis and a portion on a taxable basis, only the tax-free portion shall be delivered hereunder and the Agreed Share Value thereof shall be appropriately adjusted, unless such delivery would create a substantial risk that the Reorganization would fail to be tax-free under Code Sections 355(a) and (c); and any reference to "AT&T Shares" in this Agreement shall be deemed a reference to the New Consideration required to be delivered under this Section 7.31(a)(iii), except as the context otherwise requires; (iv) AT&T shall set a record date that is prior to Closing to split or combine AT&T Shares, the Comcast Entities will deliver hereunder all such AT&T Shares, and the Agreed Share Value shall be appropriately adjusted to reflect such stock split or combination; and (v) set a record date that is prior to Closing to make any other change in the AT&T Shares, appropriate adjustment will be made in respect of such change. The adjustment set forth in this Section 7.31 shall apply only to AT&T Shares acquired by Comcast or its Affiliates on or before the record date (or the effective date, in the case of clause (iii)) of any action specified above. (b) If a record date for any Distribution occurs after the date hereof and prior to the Closing Date: (i) for each AT&T Share that any Comcast Entity purchases after such record date and delivers to AT&T pursuant to this Agreement, such 67

Comcast Entity shall also purchase and deliver to AT&T the number of Tracking Share(s) (or portion thereof) distributed in respect of one AT&T Share pursuant to any such Distribution and any reference to "Agreed Share Value" shall include a reference to the purchase price paid by the Comcast Entity for such Tracking Share(s) (or portion thereof); and (ii) any reference to "AT&T Share" shall include a reference to the number of Tracking Share(s) (or portion thereof) so distributed. 7.32. Losses Relating to Failure to Obtain Franchise Consents. All costs and other Losses imposed by franchise authorities arising out of or resulting from the failure to obtain by the Closing Time any consents relating to the Transfer of AT&T Systems Franchises to the Comcast Entities (i) will be shared equally between Comcast and AT&T, if the condition set forth in Section 8.2.5 has been satisfied at Closing or (ii) will be borne solely by Comcast, if Comcast waives the condition set forth in Section 8.2.5. 7.33. Cooperation with respect to Section 8.1.2. If all conditions to the Closing set forth in Article 8 have been satisfied or (to the extent legally permissible) waived, other than the condition set forth in Section 8.1.2, the Parties will discuss in good faith reducing the size of the Reorganization so that the size of the Reorganization is maximized to the extent practicable and the condition set forth in Section 8.1.2 would be satisfied after giving effect to such reduction, so long as such reduction would not create a substantial risk that the Reorganization would fail to be tax-free under Code Sections 355(a) and (c) or create a substantial risk that the Internal Restructuring would fail to be tax-free. 8.

By either Comcast or AT&T upon written notice to the other, if any of the conditions to its or its Affiliates' obligations set forth in Sections 8.1, 8.2 and 8.3, respectively, are not or could not be satisfied such that Closing occurs on or before October 31, 2001 for any reason other than a breach or default by such Parent or its Affiliates of their 72

covenants, agreements or other obligations under this Agreement, or any of such Parent's representations herein not being true and accurate when made or when otherwise required by this Agreement to be true and accurate; or 10.1.3. By either Comcast or AT&T if an injunction, restraining order or decree of any nature of any Governmental Authority of competent jurisdiction is issued that prohibits the consummation of any of the transactions contemplated hereby and such injunction, restraining order or decree is final and nonappealable; provided, however, that the Party seeking to terminate this Agreement pursuant to this Section 10.1.3 has, subject to the terms hereof, used commercially reasonable efforts to have such injunction, order or decree vacated or denied. 10.2. Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, all obligations of the Parties under this Agreement will terminate, except for the obligations set forth in Sections 7.15 and 12.13. Termination of this Agreement pursuant to Sections 10.1.2 or 10.1.3 will not limit or impair any remedies that AT&T or Comcast may have pursuant to the terms of this Agreement with respect to a breach or default by the other of their covenants, agreements or obligations under this Agreement. 11. SURVIVAL; INDEMNIFICATION. 11.1. Indemnification by AT&T. From and after the Closing, AT&T will indemnify and hold harmless Comcast and its Affiliates (including the Transferred Entities), and its and their respective shareholders, officers, directors, partners, employees, agents, successors and assigns, and any Person claiming by or through any of them, as the case may be, from and against any and all Losses to the extent arising out of or resulting from: (a) any representations and warranties made by any AT&T Party in this Agreement, except for those contained in Sections 6.5 and 6.15 hereof or in any Transaction Document not being true and accurate when made or as of the Closing (or, if given as of a certain date, not being true as of such certain date) with the same effect as if made as of the Closing (or such date); (b) any failure by AT&T or its Affiliates or, prior to Closing, any Transferred Entity to perform any of its covenants, agreements, or obligations in this Agreement or in any Transaction Document (other than Losses to the extent arising out of or resulting from AT&T Excluded Liabilities or covenants, agreements, or obligations contained in Sections 7.2.16, 7.2.17, 7.28, 7.29 and 7.30 hereof); (c) the AT&T Excluded Liabilities; and (d) the AT&T Excluded Assets. AT&T will not make any claim against any Transferred Entity for reimbursement of or contribution to any of AT&T's indemnification obligations under this Agreement. 11.2. Indemnification by Comcast. From and after the Closing, Comcast will indemnify and hold harmless AT&T and its Affiliates, and its and their respective shareholders, officers, directors, partners, employees, agents, successors and assigns, and any Person claiming 73

by or through any of them, as the case may be, from and against any and all Losses to the extent arising out of or resulting from: (a) any representations and warranties made by any Comcast Party in this Agreement, except for those contained in Section 5.5 hereof, or in any Transaction Document not being true and accurate when made or as of the Closing (or, if given as of a certain date, not being true as of such certain date) with the same effect as if made as of the Closing (or such date); (b) any failure by any Comcast Party or its Affiliates or, subsequent to the Closing, any Transferred Entity to perform any of its covenants, agreements, or obligations in this Agreement or in any Transaction Document (other than those contained in Sections 7.28 and 7.30 hereof); and (c) the Comcast Assumed Obligations and Liabilities. 11.3. Third Party Claims. Upon receipt by any Person of notice of any claim, action, suit or proceeding by any Third Party (collectively, an "Action"), which Action is subject to indemnification under this Article 11, such Person (the "Indemnified Party") will give reasonable written notice to the Party from whom indemnification is claimed (the "Indemnifying Party"); provided that the failure of any Indemnified Party to so deliver notice shall not relieve the Indemnifying Party of its obligations under this Article 11, except to the extent the Indemnifying Party is prejudiced by such failure. The Indemnified Party will be entitled, at the sole expense and liability of the Indemnifying Party, to exercise full control of the defense, compromise or settlement of any such Action unless the Indemnifying Party, within a reasonable time after the giving of such notice by the Indemnified Party, (i) notifies the Indemnified Party in writing of the Indemnifying Party's intention to assume such defense, (ii) retains legal counsel reasonably satisfactory to the Indemnified Party to conduct the defense of such Action and (iii) admits in writing to the Indemnified Party the Indemnifying Party's liability to the Indemnified Party for such Action to the extent provided in this Agreement. The other Party will cooperate with the Party assuming the defense, compromise or settlement of any such Action in accordance with this Agreement in any manner that such party reasonably may request. The Party controlling the defense, compromise or settlement of an Action shall act in good faith with respect thereto. If the Indemnifying Party so assumes the defense of any such Action, the Indemnified Party will have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement of the Action (in which case the Indemnifying Party shall cooperate in providing information to the Indemnified Party about the Action), but the fees and expenses of such counsel will be at the expense of the Indemnified Party unless (i) the Indemnifying Party has agreed to pay such fees and expenses, (ii) any relief other than the payment of money damages is sought against the Indemnified Party or (iii) the Indemnified Party has been advised by independent counsel that there may be one or more defenses available to it which are different from or additional to those available to the Indemnifying Party, and in any such case that portion of the fees and expenses of such separate counsel that are reasonably related to matters covered by the indemnity provided in this Article 11 will be paid by the Indemnifying Party, provided that the Indemnifying Party shall not be obligated to pay the expenses of more than one separate counsel in each jurisdiction for each Indemnified Party so entitled to separate counsel. No Indemnified Party will settle or 74

compromise any such Action for which it is entitled to indemnification under this Agreement without the prior written consent of the Indemnifying Party. No Indemnifying Party will settle or compromise any such Action in which any relief other than the payment of money damages is sought against any Indemnified Party, unless the Indemnified Party consents in writing to such compromise or settlement. 11.4. Limitations on Indemnification. (a) AT&T will have no liability under Section 11.1(a) unless the amount of Losses otherwise subject to its indemnification obligations thereunder exceeds 0.55% of the Final System Value for all Systems (the "AT&T Minimum Damage Requirement"), in which case AT&T shall be liable only for such excess; provided that the AT&T Minimum Damage Requirement will not apply to any Losses resulting from or arising out of breaches of the representations and warranties in Section 6.1, 6.2, 6.3, 6.4(a), 6.4(b), or 6.18. The maximum liability of AT&T under Section 11.1(a) shall not exceed 4.7% of the Final System Value for all Systems (the "AT&T Cap"); provided that the AT&T Cap shall not apply to breaches of the representations and warranties in Sections 6.1, 6.2, 6.3, 6.4(a), 6.4(b), or 6.18. (b) Comcast will have no liability under Section 11.2(a) unless the amount of Losses otherwise subject to its indemnification obligations thereunder exceeds 0.55% of the Final System Value for all Systems (the "Comcast Minimum Damage Requirement"), in which case Comcast shall be liable only for such excess; provided that the Comcast Minimum Damage Requirement will not apply to any Losses resulting from or arising out of breaches of the representations and warranties in Section 5.1, 5.2, 5.3(a), or 5.3(b), 5.4 or 5.6. The maximum liability of Comcast under Section 11.2(a) shall not exceed 4.7% of the Final System Value for all Systems (the "Comcast Cap"); provided that the Comcast Cap shall not apply to breaches of the representations and warranties in Section 5.1, 5.2, 5.3(a), 5.3(b), 5.4 or 5.6. (c) The representations and warranties of Comcast and the AT&T Parties in this Agreement and any Transaction Document, and the corresponding indemnification obligations under Sections 11.1(a) and 11.2(a) will survive Closing for a period of nine months, except for the representations in Sections 5.4 and 6.3, which shall survive indefinitely, and except as set forth in Section 7.30. Notwithstanding the foregoing, the liability of the parties will extend beyond the nine-month period following Closing with respect to any claim which has been asserted in a bona fide written notice before the expiration of such nine-month period specifying in reasonable detail the facts and circumstances giving rise to such right. The indemnification obligations under Sections 11.1(b) and 11.2(b) (in each case, other than the covenants, agreements and obligations which by their terms are to be performed after the Closing) and under Section 11.1(c) will survive Closing for a period of twelve (12) months (except, in the case of Section 11.1(c), for indemnification obligations for AT&T Excluded Liabilities which do not relate to the AT&T Systems or AT&T's Cable Business, which shall survive indefinitely). Notwithstanding the foregoing, the liability of the parties will extend beyond the twelve (12)-month period following Closing with respect to any claim which has been asserted in a bona fide written notice before the expiration of such 12-month period specifying in reasonable detail the facts and circumstances giving rise to such right. For this purpose, proper and timely notice shall be deemed given by all indemnified persons on the date hereof, and no further notice shall be required, with respect to all items set forth on the disclosure 75

schedules provided by the Parties in connection with this Agreement and with respect to pre-Closing accounts payable and franchise fees for which AT&T is responsible under Section 7.25. (d) All Losses resulting from the failure to obtain by the Closing Time any consents for the Transfer of AT&T Systems Contracts to the Comcast Entities (by the transfer of the stock of the AT&T Cable Subsidiaries to the Comcast Entities) (other than Systems Contracts that are identified with an "*" on Schedule 6.4) shall be borne solely by Comcast up to an amount equal to $2,000,000 and thereafter shall be shared equally between Comcast and AT&T. 11.5. Payments for Indemnification Amounts. Amounts payable by a Party in respect of any Losses that are subject to the indemnification obligations of such Party under Section 11.1 or 11.2 will be payable by the Indemnifying Party within five (5) days of receiving written notice of such Losses from the Indemnified Party, and will bear interest at the Prime Rate plus three percent (3%) beginning on the sixth day after receipt of such written notice and ending on the date of payment of indemnification by the Indemnifying Party. 11.6. Exclusive Remedy. The Parties hereby agree that the rights set forth in this Article 11 shall be each Party's and its Affiliates' sole and exclusive remedies against the other Party and its Affiliates for any claims arising after the Closing Time and relating to any liability of an AT&T System arising prior to the Closing Time. 11.7. Tax Indemnification. The above provisions of this Article 11 shall not apply to Tax indemnification matters, which matters shall instead be governed by Section 7.30. 12. MISCELLANEOUS PROVISIONS. 12.1. Parties Obligated and Benefited. Subject to the limitations set forth below, this Agreement will be binding upon each of the Parties and their respective assigns and successors in interest and will inure solely to the benefit of the Parties and their respective assigns and successors in interest, and no other Person will be entitled to any of the benefits conferred by this Agreement. 12.2. Notices. Any notice, request, demand, waiver or other communication required or permitted to be given under this Agreement to any Party will be in writing and will be deemed to have been duly given only if delivered in person or by first class, prepaid, registered or certified mail, or delivered by courier or, if receipt is confirmed, delivery by telecopier: To any AT&T Entity: 295 North Maple Avenue Basking Ridge, New Jersey 07920 Attention: Marilyn Wasser Telecopy: 908-221-6618 76

Right to Specific Performance. Each Party acknowledges that the unique nature of the Assets to be exchanged hereunder pursuant to this Agreement renders money damages an inadequate remedy for the breach by any Party of its obligations under this Agreement, and the Parties agree that, in the event of such breach, the Parties will upon proper action instituted by either of them, be entitled to a decree of specific performance of this Agreement or other equitable relief. 12.4. Waiver. This Agreement or any of its provisions may not be waived except in writing. The failure of any Party to enforce any right arising under this Agreement on one or 77

more occasions will not operate as a waiver of that or any other right on that or any other occasion. 12.5. Captions. The captions of this Agreement are for convenience only and do not constitute a part of this Agreement. 12.6. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York (other than its rules of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby). 12.7. Time. Time is of the essence under this Agreement. If the last day permitted for the giving of any notice or the performance of any act required or permitted under this Agreement falls on a day which is not a Business Day, the time for the giving of such notice or the performance of such act will be extended to the next succeeding Business Day. 12.8. Late Payments. Except as otherwise provided herein, if any Party fails to pay the other any amounts when due under this Agreement, the amounts due will bear interest from the due date to the date of payment at the Prime Rate plus two percent (2%), adjusted as and when changes in the Prime Rate are made. 12.9. Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original. 12.10. Entire Agreement. This Agreement (including the Transaction Documents and the Schedules and Exhibits referred to in this Agreement, which are incorporated in and constitute a part of this Agreement), contains the entire agreement of the Parties with respect to the subject matter hereof, and supersedes all prior oral or written agreements and understandings with respect to such subject matter, including, without limitation, (i) the letter agreement, dated as of May 4, 1999 between AT&T and Comcast (but shall not supersede the following paragraphs thereof: paragraph 2 {Termination of the Merger Agreement}, paragraph 11.(b) {No Trading During Valuation Period}, paragraph 12 {Telephony Agreements} and, to the extent related to the foregoing, paragraphs 14, 15, 17, and 19-24) and (ii) the Amendment to such letter agreement dated as of November 16, 1999 (but shall not supersede paragraph 4 thereof). This Agreement does not supersede the Asset Exchange Agreement dated as of August 11, 2000 by and among AT&T, the AT&T Parties (as defined therein), Comcast and the Comcast Parties (as defined therein) to the extent relating to the transactions with respect thereto. This Agreement may not be amended or modified, except by a writing signed by all of the Parties hereto. 12.11. Severability. Any term or provision of this Agreement that is invalid or unenforceable will be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining rights of the Person intended to be benefited by such provision or any other provisions of this Agreement. 12.12. Construction. This Agreement has been negotiated by the Parties and their respective legal counsel, and legal or other equitable principles that might require the construction of this Agreement or any provision of this Agreement against the Party drafting this Agreement will not apply in any construction or interpretation of this Agreement. 78

12.13. Expenses. Except as otherwise expressly provided in this Agreement, each Party will pay all of its expenses, including attorneys' and accountants' fees, in connection with the negotiation of this Agreement, the performance of its obligations and the consummation of the transactions contemplated by this Agreement. 12.14. Risk of Loss. The risk of any loss or damage to the AT&T Assets resulting from fire, theft or other casualty (except reasonable wear and tear) will be borne by the owner thereof at all times prior to the Closing Time. In the event of any such loss or damage after May 4, 1999, AT&T will immediately notify Comcast in writing of that fact and the System Value for the applicable AT&T System or AT&T Systems will be reduced in the amount of the deductible under the casualty insurance policies insuring such Assets, and all insurance proceeds paid or payable as a result of the occurrence of the event resulting in such loss or damage will be delivered at the Closing by AT&T to Comcast, or the rights thereto will be assigned, if not yet paid over by the insurer, to AT&T. If such loss is not fully insured for replacement cost, then the System Value for the applicable AT&T System or AT&T Systems will further be reduced by the cost to repair or replace such Assets, less any insurance proceeds paid or payable with respect thereto. In either case, the obligations under this Section 12.14 to make adjustment or pay or assign insurance proceeds will not apply to the extent that any insurance proceeds or deductibles are applied to replace or restore such loss or damage prior to Closing. If, on or prior to the Closing Time, all or any part of or interest in the AT&T Assets, as appropriate, is taken or condemned as a result of a Governmental Authority's exercise of its powers of eminent domain, or if a Governmental Authority having such power informs a Party that it intends to condemn all or any part of the AT&T Assets (such event being called, in either case, a "Taking"), then (i) Comcast may elect, in the name of AT&T, to negotiate for, claim, contest and receive all damages with respect to the Taking, (ii) AT&T will be relieved of its obligation to convey to Comcast those of its Assets that were the subject of the Taking, (iii) at the Closing, AT&T will assign to Comcast all of its rights to damages payable as a result of the Taking, and will pay to Comcast all damages previously paid to it in connection with the Taking, and (iv) following the Closing, AT&T will give to Comcast any further assurances of such rights and assignment with respect to the Taking as Comcast reasonably may request from time to time. No amount payable under this Section 12.14 will be taken into account in calculating the Working Capital Adjustment Amount. 12.15. Jurisdiction. Except as otherwise expressly provided in this Agreement, the Parties agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement, the Transaction Documents or the transactions contemplated hereby or thereby may be brought in the United States District Court for the Southern District of New York or any other New York State court sitting in New York City, and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without 79

limiting the foregoing, each Party agrees that service of process on such Party as provided in Section 12.2 shall be deemed effective service of process on such Party. 12.16. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.
