Subject to the provisions of this Plan, at the Effective Time, automatically by virtue of the Corporate Merger and without any action on the part of any party or stockholder: (A) OUTSTANDING FIRST UNION COMMON STOCK. Each share of First Union Common Stock (and each attached right (a "First Union Right") issued pursuant to the Amended and Restated Shareholder Protection Rights Agreement, dated as of October 15, 1996 (as amended, the "First Union Rights Agreement"), between First Union and First Union National Bank, as Rights Agent) issued and outstanding immediately prior to the Effective Time shall be unchanged and shall remain issued and outstanding. (B) OUTSTANDING CORESTATES COMMON STOCK. Each share (excluding shares held by CoreStates or any of its subsidiaries (as defined in SECTION 8.08) or by First Union or any of its subsidiaries, in each case other than in a trust, fiduciary or nominee capacity or as a result of debts previously contracted ("Treasury Shares")) of CoreStates Common Stock issued and outstanding immediately prior to the Effective Time shall become and be converted into 1.62 shares (subject to possible adjustment as set forth in SECTIONS 2.05 AND 7.01(F), the "Exchange Ratio") of First Union Common Stock (with the appropriate number of First Union Rights, which shall be attached thereto or represented by Rights Certificates in accordance with the First Union Rights Agreement). (C) TREASURY SHARES. Each Treasury Share immediately prior to the Effective Time shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor. 2.02. STOCKHOLDER RIGHTS; STOCK TRANSFERS. At the Effective Time, holders of CoreStates Common Stock shall cease to be, and shall have no rights as, stockholders of CoreStates, other than to receive any dividend or other distribution with respect to the CoreStates Common Stock with a record date occurring prior to the Effective Time and the consideration provided under this ARTICLE II. After the Effective Time, there shall be no transfers on the stock transfer books of CoreStates or the Continuing Corporation of shares of CoreStates Common Stock. 3 2.03. FRACTIONAL SHARES. Notwithstanding any other provision hereof, no fractional shares of First Union Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Corporate Merger; instead, First Union shall pay to each holder of CoreStates Common Stock who would otherwise be entitled to a fractional share an amount in cash determined by multiplying such fraction by the average of the last sale prices of First Union Common Stock, as reported by the New York Stock Exchange (the "NYSE") Composite Transactions tape (as reported in THE WALL STREET JOURNAL or, if not reported therein, in another authoritative source), for the five NYSE trading days immediately preceding the Effective Date. 2.04. EXCHANGE PROCEDURES. (A) As promptly as practicable after the Effective Date, First Union shall send or cause to be sent to each former holder of shares (other than Treasury Shares) of CoreStates Common Stock of record immediately prior to the Effective Time transmittal materials for use in exchanging such stockholder's certificates formerly representing CoreStates Common Stock ("Old Certificates") for the consideration set forth in this ARTICLE II. The certificates representing the shares of First Union Common Stock ("New Certificates") into which shares of such stockholder's CoreStates Common Stock are converted at the Effective Time and any checks in respect of a fractional share interest or dividends or distributions which such person shall be entitled to receive will be delivered to such stockholder only upon delivery to First Union National Bank, as Exchange Agent (the "Exchange Agent") of Old Certificates representing all of such shares of CoreStates Common Stock (or indemnity reasonably satisfactory to First Union and the Exchange Agent, if any of such certificates are lost, stolen or destroyed) owned by such stockholder. No interest will be paid on any such cash to be paid in lieu of fractional share interests or dividends or distributions which any such person shall be entitled to receive pursuant to this ARTICLE II upon such delivery. Old Certificates surrendered for exchange by any CoreStates Affiliate (as defined in SECTION 5.07) shall not be exchanged for New Certificates until First Union has received a written agreement from such person as specified in SECTION 5.07. (B) Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of CoreStates Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (C) At the election of First Union, no dividends or other distributions with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificates representing CoreStates Common Stock until such Old Certificates have been surrendered for exchange for New Certificates. After becoming so entitled in accordance with this SECTION 2.04, the record holder thereof also shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of First Union Common Stock such holder had the right to receive upon surrender of the Old Certificate. 2.05. ANTI-DILUTION PROVISIONS. In the event First Union changes (or establishes a record date for changing) the number of shares of First Union Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding First Union Common Stock and the record date therefor shall be prior to the Effective Date, the Exchange Ratio shall be proportionately adjusted. 2.06. OPTIONS. (A) From and after the Effective Time, all employee and director stock options to purchase shares of CoreStates Common Stock (each, a "CoreStates Option"), which are then outstanding and unexercised, shall be converted into and become options to purchase shares of First Union Common Stock, and First Union shall assume each such CoreStates Option in accordance with the terms of the plan and agreement by which it is evidenced, including but not limited to the accelerated vesting of such CoreStates Options which shall occur in connection with and by virtue of the Corporate Merger as and to the extent required by such plans and agreements; PROVIDED, HOWEVER, that from and after the Effective Time (i) each such CoreStates Option assumed by First Union may be exercised solely to purchase shares of First Union Common Stock, (ii) the number of shares of First Union Common Stock purchasable upon exercise of such CoreStates Option shall be equal to the number of shares of CoreStates Common Stock that were purchasable under such CoreStates Option immediately prior to the Effective Time multiplied by the Exchange Ratio and rounding to the nearest whole share, and (iii) the per share exercise price under each such CoreStates Option shall be adjusted by dividing the per share exercise price of each such CoreStates Option by the Exchange Ratio, and rounding up to the nearest cent. The terms of each CoreStates Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, recapitalization or other similar transaction with respect to First Union Common Stock on or subsequent to the Effective Date. Notwithstanding the foregoing, the number of shares and the per share 4 exercise price of each CoreStates Option which is intended to be an "incentive stock option" (as defined in SECTION 422 of the Code) shall be adjusted in accordance with the requirements of SECTION 424 of the Code. Accordingly, with respect to any incentive stock options, fractional shares shall be rounded down to the nearest whole number of shares and where necessary the per share exercise price shall be rounded up to the nearest cent. (B) Prior to the Effective Time, First Union shall reserve for issuance the number of shares of First Union Common Stock necessary to satisfy First Union's obligations under SECTION 2.06(A). Promptly after the Effective Time, First Union shall file with the SEC a registration statement on an appropriate form under the Securities Act with respect to the shares of First Union Common Stock subject to options to acquire First Union Common Stock issued pursuant to SECTION 2.06(A) hereof, and shall use its reasonable best efforts to maintain the current status of the prospectus contained therein, as well as comply with any applicable state securities or "blue sky" laws, for so long as such options remain outstanding.

First Union will deliver to CoreStates copies of all qualified retirement plans and welfare benefit plans. (2) Except as Previously Disclosed, to its knowledge, each of its Compensation and Benefit Plans has been operated and administered by it in all material respects in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act, or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act and any other applicable law have been timely made. Except as Previously Disclosed, to its knowledge, each of its Compensation and Benefit Plans which is an "employee pension benefit plan" within the meaning of SECTION 3(2) of ERISA (a "Pension Plan") and which is intended to be qualified under SECTION 401(A) of the Code has received a favorable determination letter (including a determination that the related trust under such Compensation and Benefit Plan is exempt from tax under SECTION 501(A) of the Code) from the IRS for "TRA" (as defined in Rev. Proc. 93-39), or will file for such determination letter prior to the expiration of the remedial amendment period for such Compensation and Benefit Plan, and it is not aware of any circumstances likely to result in revocation of any such favorable determination letter. There is no pending or, to its knowledge, threatened legal action, suit or claim relating to the Compensation and Benefit Plans. Except as Previously Disclosed, to its knowledge, neither it nor any of its subsidiaries has engaged in a transaction, or omitted to take any action, with respect to any Compensation and Benefit Plan that would reasonably be expected to subject it or any of its subsidiaries to a tax or penalty imposed by either SECTION 4975 of the Code or SECTION 502 of ERISA, assuming for purposes of SECTION 4975 of the Code that the taxable period of any such transaction expired as of the date hereof. (3) No liability (other than for payment of premiums to the PBGC which have been made or will be made on a timely basis) under Title IV of ERISA has been or is reasonably expected to be incurred by it or any of its subsidiaries with respect to any ongoing, frozen or terminated "single-employer plan", within the meaning of SECTION 4001(A)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (an "ERISA Affiliate") which is considered one employer with it under SECTION 4001(A)(14) of ERISA or SECTION 414(B) OR (C) of the Code (an "ERISA Affiliate Plan"). None of it, any of its subsidiaries or any ERISA Affiliate has contributed, or has been obligated to contribute, to a multiemployer plan under Subtitle E of Title IV of ERISA at any time since September 26, 1980. No notice of a "reportable event", within the meaning of SECTION 4043 of ERISA, for which the 30-day reporting requirement has not been waived, has been required to be filed for any Compensation and Benefit Plan or by any ERISA Affiliate Plan within the 12-month period ending on the date hereof. The PBGC has not instituted proceedings to terminate any Pension Plan or ERISA Affiliate Plan and, to it's knowledge, no condition exists that presents a risk that such proceedings will be instituted. To its knowledge, there is no pending investigation or enforcement action by the PBGC, the Department of Labor (the "DOL") or IRS or any other governmental agency with respect to any Compensation and Benefit Plan. Under each Pension Plan and ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Plan, the actuarially determined present value of all "benefit liabilities", within the meaning of SECTION 4001(A)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Pension Plan or ERISA Affiliate Plan), did not exceed the then current value of the assets of such Pension Plan or ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Pension Plan or ERISA Affiliate Plan nor any amendment or other change to such Pension Plan or ERISA Affiliate Plan that would increase the amount of benefits thereunder which in either case reasonably could be expected to change such result. (4) All contributions required to be made under the terms of any Compensation and Benefit Plan or ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which it or any of its subsidiaries is a party have been timely made or have been reflected on its financial statements to the extent 10 required by generally accepted accounting principles. Neither any Pension Plan nor any ERISA Affiliate Plan has an "accumulated funding deficiency" (whether or not waived) within the meaning of SECTION 412 of the Code or SECTION 302 of ERISA and all required payments to the PBGC with respect to each Pension Plan or ERISA Affiliate Plan have been made on or before their due dates. None of it, any of its subsidiaries or any ERISA Affiliate (x) has PROVIDED, or would reasonably be expected to be required to provide, security to any Pension Plan or to any ERISA Affiliate Plan pursuant to SECTION 401(A)(29) of the Code, or (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under SECTION 412(N) of the Code or pursuant to ERISA.

It and its subsidiaries have taken all requisite action (including without limitation the making of claims and the giving of notices) pursuant to its directors' and officers' liability insurance policy or policies in order to preserve all rights thereunder with respect to all matters (other than matters arising in connection with this Plan and the transactions contemplated hereby) that are known to it. (P) TAKEOVER LAWS; DISSENTERS RIGHTS. It has taken all action required to be taken by it in order to exempt this Plan and the relevant Stock Option Agreement, and the transactions contemplated hereby and thereby, from, and this Plan and the relevant Stock Option Agreement and the transactions contemplated hereby and thereby are exempt from, the requirements of any "moratorium", "control share", "fair price", "affiliate transaction", "control transaction", "business combination" or other antitakeover laws and regulations (collectively, the "Takeover Laws") of (i) the State of North Carolina in the case of the representations and warranties of First Union, including ARTICLES 9 AND 9A of the NCBCA, and (ii) the Commonwealth of Pennsylvania in the case of the representations and warranties of CoreStates, including, without limitation, Chapter 25 of the PBCL.

(S) POOLING; REORGANIZATION.

(T) REGULATORY APPROVALS. As of the date hereof, it is aware of no reason why the regulatory approvals and consents referred to in SECTION 6.02 will not be received without the imposition of a condition or requirement described in the proviso thereto. (U) NO MATERIAL ADVERSE EFFECT. Since December 31, 1996, except as Previously Disclosed in its SEC Documents filed with the SEC on or before the date hereof or in any Section of its Disclosure Schedule, (i) it and its subsidiaries have conducted their respective businesses in the ordinary and usual course (excluding the incurrence of expenses related to this Plan and the transactions contemplated hereby) and (ii) no event has occurred or circumstance arisen that, individually or taken together with all other facts, circumstances and events (described in any paragraph of SECTION 4.03 or otherwise), is reasonably likely to have a Material Adverse Effect with respect to it.

(2) In the case of the representations and warranties of First Union, the affirmative vote of the holders of a majority of (a) the outstanding shares of First Union Common Stock is the only vote of the holders of any class or series of capital stock of First Union necessary to approve this Plan, and (b) the total votes cast (provided that the total votes cast represent over 50% of all securities entitled to vote) by the holders of First Union Common Stock is the only vote of the holders of any class or series of capital stock of First Union necessary to approve the amendment to its articles or incorporation to increase the number of authorized shares of First Union Common Stock from 750,000,000 to 2,000,000,000. (3) In the case of the representations and warranties of First Union, First Union has heretofore provided CoreStates with a complete and correct copy of the First Union Rights Agreement, including all amendments and exhibits thereto. First Union has taken all necessary action so that none of the execution of this Agreement or the First Union Stock Option Agreement, the acquisition of shares of First Union Common Stock upon exercise of the option contained in the First Union Stock Option Agreement or the consummation of the Mergers will (i) cause the Rights issued pursuant to the First Union Rights Agreement to become exercisable, (ii) cause any person to become an Acquiring Person (as such term is defined in the First Union Rights Agreement) or (iii) give rise to a Separation Time (as such term is defined in the First Union Rights Agreement). V. COVENANTS CoreStates hereby covenants to and agrees with First Union, and First Union hereby covenants to and agrees with CoreStates, that: 5.01. REASONABLE BEST EFFORTS. Subject to the terms and conditions of this Plan, it shall use its reasonable best efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, so as to permit consummation of the Mergers as promptly as reasonably practicable and to otherwise enable consummation of the transactions contemplated hereby, including, without limitation, obtaining (and cooperating with the other party hereto in obtaining) any consent, authorization, order or approval of, or any exemption by, any Regulatory Authority and any other third party that is required to be obtained by First Union or CoreStates or any of their 12 respective subsidiaries in connection with the Mergers and the other transactions contemplated by this Plan, and using reasonable efforts to lift or rescind any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby, and using reasonable efforts to defend any litigation seeking to enjoin, prevent or delay the consummation of the transactions contemplated hereby or seeking material damages, and each shall cooperate fully with the other parties hereto to that end. 5.02.

Each of them shall take, in accordance with applicable law, NYSE rules and its respective articles of incorporation and by-laws, all action necessary to convene, respectively, (A) an appropriate meeting of stockholders of First Union to consider and vote upon (i) the approval of an amendment to the articles of incorporation of First Union to increase the number of authorized shares of First Union Common Stock from 750,000,000 to 2,000,000,000 and (ii) the approval of this Plan, and (iii) any other stockholder approval matters required for consummation of the Corporate Merger and the transactions contemplated hereby (the "First Union Meeting"), and (B) an appropriate meeting of stockholders of CoreStates to consider and vote upon the approval of this Plan and any other stockholder approval matters required for consummation of the Corporate Merger and the transactions contemplated hereby (the "CoreStates Meeting"; each of the First Union Meeting and the CoreStates Meeting, a "Meeting"), respectively, as promptly as practicable after the Registration Statement (as defined in SECTION 5.03) is declared effective. The Board of Directors of each of First Union and CoreStates will recommend approval of such matters, and each of First Union and CoreStates will take all reasonable lawful action to solicit such approval by its respective stockholders, provided that each of First Union and CoreStates may withdraw, modify or change in an adverse manner to the other party its recommendations if the Board of Directors of such party, after having consulted with and based upon the advice of outside counsel, determines in good faith that the failure to so withdraw, modify or change its recommendation could constitute a breach of the fiduciary duties of such party's Board of Directors under applicable law. In addition, nothing in this SECTION 5.02 or elsewhere in this Plan shall prohibit accurate disclosure by either party of information that is required to be disclosed in the Registration Statement or the Joint Proxy Statement or any other document required to be filed with the SEC (including without limitation a Solicitation/Recommendation Statement on Schedule 14D-9) or otherwise required to be publicly disclosed by applicable law or regulation or the rules of the NYSE. 5.03.

(C) No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Plan, or the conditions to either party's obligation to consummate the transactions contemplated by this Plan. 5.06. ACQUISITION PROPOSALS. Without the prior written consent of the other, neither CoreStates nor First Union shall, and each of them shall cause its respective subsidiaries and its and its subsidiaries' officers and directors not to, solicit or encourage inquiries with respect to, or engage in negotiations concerning, or provide any confidential information or assistance to, or have any discussions with, any person relating to, any tender offer or exchange offer for, or any proposal for the acquisition of a substantial equity interest in, or a substantial portion of the assets or deposits of, such party or any of its significant subsidiaries (each an "Acquisition Proposal"). Notwithstanding the foregoing, each of CoreStates and First Union may, and may authorize and permit its officers, directors, agents, advisors, attorneys, accountants and affiliates (collectively, "Representatives") to, provide third parties with confidential information, have discussions or negotiations with or otherwise facilitate any effort or attempt by such third party to make or implement an Acquisition Proposal not solicited in violation of this Agreement if such party's Board of Directors, after having consulted with and based upon the advice of outside counsel, determines in good faith that the failure to take such actions could constitute a breach of the fiduciary duties of such party's Board of Directors under applicable law; PROVIDED, that such party shall promptly advise the other party following the receipt of any Acquisition Proposal and the material details thereof; and PROVIDED, FURTHER, that prior to delivery of confidential information relating to such party or providing access to such party's books, records or properties in connection therewith, such party shall have entered into a confidentiality agreement substantially similar to the one previously entered into between CoreStates and First Union.

CoreStates and First Union shall also consult with respect to the character, amount and timing of restructuring charges to be taken by each of them in connection with the transactions contemplated hereby and shall take such charges in accordance with generally accepted accounting principles, as may be mutually agreed upon. No party's representations, warranties and covenants contained in this Plan shall be deemed to be untrue or breached in any respect for any purpose as a consequence of any modifications or changes to such policies and practices which may be undertaken on account of this SECTION 5.08. 5.09.

First Union's obligations under this SECTION 5.13(A) shall continue in full force and effect for a period of six years after the Effective Date; provided that all rights to indemnification in respect of any claim, action, suit, proceeding or investigation made, asserted or commenced within such six year period shall continue until the final disposition of such claim, action, suit, proceeding or investigation.

(C) Any Indemnified Party wishing to claim indemnification under SECTION 5.13(A), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify First Union thereof; provided that the failure so to notify shall not affect the obligations of First Union under SECTION 5.13(A) unless and to the extent such failure materially increases First Union's liability under such subsection (A). (D) If First Union or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any entity, then and in each case, proper provision shall be made so that the successors and assigns of First Union shall assume the obligations set forth in this SECTION 5.13. (E) First Union shall pay all reasonable Costs, including attorneys' fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided for in this SECTION 5.13.

Effective as of the merger of such plans, First Union will cause the following to occur: (1) the First Union DB Plan will provide that participants in the CoreStates DB Plan who are employed by First Union as of the date of such merger (the "CoreStates Merger Participants") will receive service credit for purposes of benefit accrual under the First Union DB Plan to the extent the CoreStates Merger Participants have earned service credit for purposes of benefit accrual under the 16 CoreStates DB Plan as of the merger of such plans; and (2) the First Union DB Plan benefit for CoreStates Merger Participants will be the greater of (a) the CoreStates DB Plan benefit determined as of the merger of such plans or (b) the First Union DB Plan benefit (determined by including benefit accrual service described in the preceding sentence). (B) SEVERANCE POLICY AND OTHER AGREEMENTS. Any employee of CoreStates or its subsidiaries at the Effective Time whose employment is terminated by his or her employer (or who otherwise would be eligible for benefits pursuant to CoreStates' severance plan and/or CoreStates' outplacement policy, as amended through and as in effect on the date immediately preceding the Effective Time (the "Severance Plan")) prior to the first anniversary of the Effective Time shall receive severance payments and benefits no less favorable than those provided pursuant to the Severance Plan. For purposes of calculating the benefits that would be payable pursuant to the Severance Plan, the employees' period of service shall include all of their cumulative period of service with First Union, CoreStates or any of their respective affiliates. First Union shall honor or cause to be honored all severance agreements and employment agreements with CoreStates's directors, officers and employees, and shall provide CoreStates' employees with outplacement services no less favorable than that in effect for First Union employees. (C) 1997 AND 1998 BONUS. First Union will maintain, or cause to be maintained, CoreStates' bonus plans, as in effect on the date hereof, through the end of the 1998 fiscal year, with bonuses to be paid to the employees participating thereunder at the greater of (i) the target level, if applicable, or (ii) such bonus as the employee would have earned if the transactions contemplated by this Agreement had not occurred, in all events on a basis consistent with past practices. (D) CREDIT FOR DEDUCTIBLES. First Union will, or will cause its affiliates to, (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the employees of CoreStates under any welfare plan that such employees may be eligible to participate in after the Effective Time, and (ii) provide each employee of CoreStates with credit for any co-payments and deductibles incurred under the CoreStates medical plans during the calendar year in which CoreStates employees become covered under similar plans offered by First Union. 5.15.

Each of CoreStates and First Union shall use its reasonable best efforts to cause to be delivered to the other party, and to First Union's directors and officers who sign the Registration Statement, a letter of KPMG Peat Marwick LLP and Ernst & Young LLP, respectively, independent auditors, dated (i) the date on which the Registration Statement shall become effective and (ii) a date shortly prior to the Effective Date, and addressed to such other party, and such directors and officers, in form and substance customary for "comfort" letters delivered by independent accountants in accordance with Statement on Auditing Standards No. 72. 5.16. DIVIDEND COORDINATION. The CoreStates Board shall cause its regular quarterly dividend record dates and payment dates for CoreStates Common Stock to be the same as First Union's regular quarterly dividend record dates and payment dates for First Union Common Stock (beginning in the quarter following the quarter in which this Plan is executed), and CoreStates shall not thereafter change its regular dividend payment dates and record dates. 5.17. NOTIFICATION OF CERTAIN MATTERS. Each of CoreStates and First Union shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

(F) POSSIBLE ADJUSTMENT. By CoreStates, if its Board of Directors so determines by a vote of a majority of the members of its entire Board, at any time during the ten-day period commencing two days after the Determination Date, if either (x) both of the following conditions are satisfied: (1) the Average Closing Price on the Determination Date of shares of First Union Common Stock shall be less than the product of 0.85 and the Starting Price; and (2) (i) the number obtained by dividing the Average Closing Price on such Determination Date by the Starting Price (such number being referred to herein as the "First Union Ratio") shall be less than (ii) the number obtained by dividing the Index Price on the Determination Date by the Index Price on the Starting Date and subtracting 0.15 from the quotient in this clause (x)(2) (ii) (such number being referred to herein as the "Index Ratio"); or (y) the Average Closing Price on the Determination Date of shares of First Union Common Stock shall be less than the product of 0.75 and the Starting Price; SUBJECT, HOWEVER, to the following four sentences. If CoreStates elects to exercise its termination right pursuant to the immediately preceding sentence, it shall give prompt written notice to First Union which notice shall specify which of clauses (x) or (y) is applicable (or if both would be applicable, which clause is being invoked); provided that such notice of election to terminate may be withdrawn at any time within the aforementioned ten-day period. During the five-day period commencing with its receipt of such notice, First Union shall have the option in the case of a failure to satisfy the condition in clause (x), of adjusting the Exchange Ratio to equal the lesser of (i) a number equal to a quotient (rounded to the nearest one-ten-thousandth), the numerator of which is the product of 0.85, the Starting Price and the Exchange Ratio (as then in effect) and the denominator of which is the Average Closing Price, and (ii) a number equal to a quotient (rounded to the nearest one-ten-thousandth), the numerator of which is the Index Ratio multiplied by the Exchange Ratio (as then in effect) and the denominator of which is the First Union Ratio. During such five-day period, First Union shall have the option, in the case of a failure to satisfy the condition in clause (y), to elect to increase the Exchange Ratio to equal a number equal to a quotient (rounded to the nearest one-ten-thousandth), the numerator of which is the product of 0.75, the Starting Price and the Exchange Ratio (as then in effect) and the denominator of which is the Average Closing 19 Price. If First Union makes an election contemplated by either of the two preceding sentences, within such five-day period, it shall give prompt written notice to CoreStates of such election and the revised Exchange Ratio, whereupon no termination shall have occurred pursuant to this SECTION 7.01(F) and this Plan shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified), and any references in this Plan to "Exchange Ratio" shall thereafter be deemed to refer to the Exchange Ratio as adjusted pursuant to this SECTION 7.01(F). For purposes of this SECTION 7.01(F), the following terms shall have the meanings indicated: "Average Closing Price" means the average of the daily last sale prices of First Union Common Stock as reported on the NYSE Composite Transactions tape (as reported in THE WALL STREET JOURNAL or, if not reported therein, in another mutually agreed upon authoritative source) for the ten consecutive full trading days in which such shares are traded on the NYSE ending at the close of trading on the Determination Date. "Determination Date" means the date on which approval of the Federal Reserve Board required for consummation of the Corporate Merger shall be received. "Index Group" means the group of each of the 14 bank holding companies listed below, the common stock of all of which shall be publicly traded and as to which there shall not have been, since the Starting Date and before the Determination Date, an announcement of a proposal for such company to be acquired or for such company to acquire another company or companies in transactions with a value exceeding 25% of the acquiror's market capitalization as of the Starting Date. In the event that the common stock of any such company ceases to be publicly traded or any such announcement is made with respect to any such company, such company will be removed from the Index Group, and the weights (which have been determined based on the number of outstanding shares of common stock) redistributed proportionately for purposes of determining the Index Price. The 14 bank holding companies and the weights attributed to them are as follows: BANK HOLDING COMPANY WEIGHTING NationsBank Corporation............................................ 18.77% BankAmerica Corporation............................................ 16.48 Banc One Corp...................................................... 10.66 U.S. Bancorp....................................................... 8.22 First Chicago NBD Corporation...................................... 7.02 Fleet Financial Group, Inc......................................... 5.20 PNC Financial Corp................................................. 4.88 SunTrust Banks, Inc................................................ 4.71 KeyCorp............................................................ 4.50 National City Corporation.......................................... 4.45 Mellon Bank Corporation............................................ 4.33 Norwest Corporation................................................ 4.06 Wachovia Corporation............................................... 3.90 Comerica Incorporated.............................................. 2.82 100.00% "Index Price" on a given date means the weighted average (weighted in accordance with the factors listed above) of the closing prices of the companies composing the Index Group. "Starting Date" means the first full trading day following the issuance of a press release announcing this Plan. "Starting Price" shall mean the last sale price per share of First Union Common Stock on the Starting Date, as reported by the NYSE Composite Transactions tape (as reported in THE WALL STREET JOURNAL or, if not reported therein, in another mutually agreed upon authoritative source). If any company belonging to the Index Group or First Union declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the Starting Date and the Determination Date, the prices for the common stock of such company or First Union shall be appropriately adjusted for the purposes of applying this SECTION 7.01(F). 7.02. EFFECT OF TERMINATION AND ABANDONMENT. In the event of termination of this Plan and the abandonment of the Mergers pursuant to this ARTICLE VII, no party to this Plan shall have any liability or further obligation to any other party 20 hereunder except (i) as set forth in SECTION 8.01, (ii) that each of the Stock Option Agreements shall be governed by its own terms as to termination and (iii) that termination will not relieve a breaching party from liability for any willful breach of this Plan giving rise to such termination.
