PREPAYMENT FROM MERGER PAYMENTS. The Pledgor authorizes and directs the Company, and its successor by merger, Winston, Inc., as pledgee, to apply any and all Merger Payments to the immediate prepayment of the Notes, to the extent of any Obligations (regardless of whether such Notes or Obligations are due or payable at such time). Merger Payments shall be applied by the Company to the Obligations as follows: (a) first, to any fees and expenses accrued and payable under any Notes evidencing Exercise Price Loans, (b) second, to accrued and unpaid interest on Exercise Price Loans, (c) third, to outstanding principal of Exercise Price Loans (in inverse order of maturity of the related Notes), (d) fourth, to any fees and expenses accrued and payable under any Notes evidencing Tax Loans, (e) fifth, to accrued and unpaid interest on Tax Loans, (f) sixth, to outstanding principal of Tax Loans (in inverse order of maturity of the related Notes) and (g) seventh, to the Pledgor in accordance with Section 12 hereof. In furtherance of this Section 2, the Pledgor agrees (i) to vote in favor of the Merger and refrain from exercising any dissenter's or appraisal rights and (ii) to cause the Merger Payments (as well as any shares of common stock of AT&T Corp. received in the Merger with respect to the Pledged Securities) to be delivered to the Company as pledgee, at 2002 Pisgah Church Road, Suite 300, Greensboro, North Carolina 27455, by so completing the box entitled "Special Delivery Instructions" on the Form of Election and Letter of Transmittal relating to the Merger and delivering it to the Company prior to the Merger, which Special Delivery Instructions shall then be irrevocable so long as any Notes remain outstanding. The Company agrees to forward promptly such Form of Election and Letter of Transmittal to the Exchange Agent specified therein, together with certificates evidencing the Pledged Securities hereunder. The Pledgor hereby grants the Company and, following the Merger, its successor, Winston, Inc. power of attorney to endorse the Pledgor's name on any check or other instrument representing Merger Payments in order that such Merger Payments may be applied to prepayment of the Notes in accordance with this Section 2. The Pledgor further agrees that, should any Merger Payments be paid to the Pledgor in lieu of the Company at any time when any Note is - 2 - outstanding, the Pledgor shall hold such payments in trust for the Company and promptly remit to the Company all such Merger Payments for application to the prepayment of the Notes. The Company and Pledgor acknowledge that the Pledged Securities are subject to that certain Voting Agreement dated as of October 2, 1998 between the Pledgor, the Company and AT&T Corp. and covenant to perform the obligations set forth therein with respect to the Pledged Securities. 3. REPRESENTATIONS AND WARRANTIES. The Pledgor represents and warrants that the Pledged Securities are, and will be upon deposit hereunder, duly and validly issued and duly and validly pledged with the Company in accordance with the law and agrees to defend the Company's right, title, lien and security interest in and to the Pledged Collateral against the claims and demands of all persons whomsoever. The Pledgor also represents and warrants to the Company that Pledgor has, and will have on deposit hereunder, good title to all of the Pledged Collateral, free and clear of all options to purchase or similar rights, claims, mortgages, pledges, liens, encumbrances and security interests of every nature whatsoever, except those granted to the Company herein, and that no consent or approval of any governmental or regulatory authority, or of any securities exchange was or is necessary to the validity of this pledge. Upon delivery to the Company of the stock certificates described on Exhibit A and the related blank stock transfer power, Pledgor represents and warrants that the security interest and lien granted hereunder will constitute a first priority security interest in and lien on the Pledged Collateral. 4. TRANSFER UPON DEFAULT. Upon the occurrence of any default under any of the Notes (a "Default"), the Company may cause all or any of the Pledged Securities to be transferred to or registered in its name or the name of its nominee or nominees. 5. VOTING RIGHTS. So long as no Default shall have occurred, the Pledgor shall be entitled to exercise the voting power with respect to the Pledged Securities as the Pledgor shall think fit, but in a manner not inconsistent with the terms hereof or of the Notes, and for that purpose the Company shall (if the Pledged Securities shall be registered in the name of the Company or its nominee) execute or cause to be executed from time to time, at the expense of the Pledgor, such proxies or other instruments in favor of the Pledgor, in such form and for such purposes as shall be reasonably required by the Pledgor and shall be specified in a written request therefor by the Pledgor to enable the Pledgor to exercise such voting power with respect to the Pledged Securities. 6. VOTING RIGHTS UPON DEFAULT. Upon the occurrence and during the continuance of any Default, the Company shall, to the extent permitted by law, have the sole and absolute right, in addition to any other rights herein contained, to exercise all voting power with respect to the Pledged Securities, and in such event the Pledgor hereby appoints the Company as the Pledgor's true and lawful proxy to vote such shares in any manner that the Company deems advisable for or against all matters that may be submitted to a vote of such shareholders. 7. DIVIDENDS. (i) In case upon the dissolution or liquidation (in whole or in part) of the Company, any sum shall be paid as a liquidating dividend or otherwise upon or - 3 - with respect to any of the Pledged Securities, and (ii) in case after a Default any other dividends of any kind shall be paid upon or with respect to any of the Pledged Securities under any circumstances, such sum shall be paid over to the Company, to be held by the Company as additional collateral hereunder. In case any stock dividend shall be declared on any of the Pledged Securities, or any shares of stock or fractions thereof shall be issued pursuant to any stock split involving any of the Pledged Securities, or any dividend or distribution of capital shall be made on any of the Pledged Securities, or any shares, obligations or other property shall be distributed upon or with respect to the Pledged Securities pursuant to a recapitalization or reclassification of the capital of the Borrower, or pursuant to the dissolution, liquidation (in whole or in part), bankruptcy or reorganization of the Company, or the merger or consolidation of the Borrower with or into another corporation, then in any such case the stock dividends, shares of stock or fraction thereof, obligations or other property so distributed shall be delivered to the Company, to be held by it as additional collateral hereunder, and all of the same shall constitute Pledged Collateral for all purposes hereof. Any cash received and retained by the Company as additional collateral hereunder pursuant to the foregoing provisions shall be held in an interest-bearing account for the benefit of the Pledgor and may at any time and from time to time be applied (in whole or in part) by the Company, at its option, to the payment of the Obligations. Notwithstanding the foregoing, Merger Payments shall be applied as set forth in Section 2 hereof. 8. REMEDIES. Immediately upon the occurrence of a Default, the Company shall have all rights and remedies of a secured party under the Uniform Commercial Code as adopted in the State of North Carolina and, without obligation to resort to other security, shall have the right at any time and from time to time to sell, resell, assign and deliver, in its discretion, all or any of the Pledged Collateral, in one or more parcels at the same or different times, and all right, title and interest, claim and demand therein and right of redemption thereof, on any securities exchange on which the Pledged Securities or any of them may be listed, or at public or private sale, for cash, upon credit or for future delivery, and in connection therewith the Company may grant options, the Pledgor hereby waiving and releasing any and all equity or right of redemption. If any of the Pledged Collateral is sold by the Company upon credit or for future delivery, the Company shall not be liable for the failure of the purchaser to purchase or pay for the same and in the event of any such failure, the Company may resell such Pledged Collateral. In no event shall the Pledgor be credited with any part of the proceeds of sale of any Pledged Collateral until cash payment of such sale has actually been received by the Company. 9. SALE OF PLEDGED COLLATERAL; APPLICATION OF PROCEEDS OF SALE. The Company shall give the Pledgor at least five (5) days' prior notice of the time and place of any public sale and of the time after which any private sale or other disposition is to be made, which notice the Pledgor agrees is reasonable, all other demand, advertisements and notices being hereby waived. The Company shall not be obligated to make any sale of Pledged Collateral if it shall determine not to do so, regardless of the fact that notice of sale may have been given. The Company may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale; and such sale may, without further notice, be made at the time and place to which the same was so adjourned. Upon each private sale of Pledged Collateral of a type - 4 - customarily sold in a recognized market and upon each public sale, the Company, or any holder of any of the Obligations, may purchase all or any of the Pledged Collateral being sold, free from any equity or right of redemption, which is hereby waived and released by the Pledgor, and may make payment therefor (by endorsement without recourse) in the Obligations in lieu of cash to the amount then due thereon, which the Pledgor hereby agrees to accept. In the case of all sales of Pledged Collateral, public or private, after all costs and expenses of every kind for sale or delivery, including brokers' and reasonable attorneys' fees, shall be deducted from the proceeds of the sale, the Company shall apply any residue to the payment of the Obligations in the order provided in Section 2 above. The balance, if any, remaining after payment in full or all of the Obligations, shall be paid to the Pledgor, subject to any duty of the Company imposed by law to the holder of any subordinate security interest in the Pledged Securities known to the Company. 10. PRIVATE SALE. The Pledgor recognizes that the Company may be unable to effect a public sale of all or a part of the Pledged Securities by reason of certain prohibitions contained in the Securities Act of 1933, as amended, as now or hereafter in effect, or in applicable Blue Sky or other state securities laws, as now or hereafter in effect, but may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obligated to agree, among other things, to acquire such Pledged Securities for their own account, for investment and not with a view to the distribution or resale thereof. The Pledgor agrees that private sales so made may be at prices and on other terms less favorable to the seller than if such Pledged Securities were sold at public sales, and that the Company has no obligation to cause the registration of such Pledged Securities for public sale under such applicable securities laws. 11. CARE OF PLEDGED COLLATERAL. The Company shall have no duty as to the collection or protection of the Pledged Collateral or any income thereof or as to the preservation of any rights pertaining thereto, beyond the safe custody of any Pledged Collateral actually in its possession. The Company shall not have any responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, redemptions, offers, tenders or other matters relative to any Pledged Collateral, whether or not the Company has or is deemed to have knowledge of such matters, except delivery of the Pledged Securities as required by the Form of Election and Letter of Transmittal relating to the Merger, or (ii) taking any necessary steps to preserve rights against any parties with respect to any Pledged Collateral. 12. TERMINATION. When all Obligations have been paid in full, this Pledge Agreement shall terminate and any remaining Pledged Collateral shall revert to the Pledgor and the right, title and interest of the Company therein shall terminate. Thereupon, the Company shall redeliver any items of Pledged Collateral then in its possession. 13. FURTHER ASSURANCES. The Pledgor shall take such further actions and execute such further documents and instruments as the Company may reasonably request in order to effectuate fully the provisions of this Pledge Agreement, including without limitation the provisions of Section 2 hereof. - 5 - 14. INSTRUCTIONS TO EXCHANGE AGENT. Any exchange agent acting in connection with the Merger may rely on a copy of this Agreement to, and is hereby authorized and directed to take all action necessary to, give full effect to the provisions of this Agreement with respect to any proceeds that would be due to the Pledgor in connection with the Merger. The Pledgor agrees to provide any further documentation required by such exchange agent to effectuate the foregoing. [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK] - 6 - 15. MISCELLANEOUS.
