1 EXHIBIT 4.1 THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO CERTAIN PROVISIONS CONTAINED HEREIN AND TO RESALE RESTRICTIONS UNDER THE SECURITIES ACT OF 1933, AS AMENDED STOCK OPTION AGREEMENT, dated June 16, 1999 between CNB Bancshares, Inc., an Indiana corporation ("ISSUER"), and Fifth Third Bancorp, an Ohio corporation ("GRANTEE"). W I T N E S S E T H: WHEREAS, Grantee and Issuer have entered into an Affiliation Agreement of even date herewith (the "AFFILIATION AGREEMENT"), which agreement has been executed by the parties hereto concurrently with this Stock Option Agreement (the "AGREEMENT"); and WHEREAS, as a condition to Grantee's entering into the Affiliation Agreement and in consideration therefor, Issuer has agreed to grant Grantee the Option (as defined below); NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Affiliation Agreement, the parties hereto agree as follows: 1. THE OPTION. (a) Issuer hereby grants to Grantee an unconditional, irrevocable option (the "OPTION") to purchase, subject to the terms hereof, up to 6,921,479 fully paid and nonassessable shares of Issuer's common stock, without par value (the "COMMON STOCK"), at a price of $42.96 per share (the "OPTION Price"); PROVIDED, however, that in the event Issuer issues or agrees to issue any shares of Common Stock (other than as permitted under the Affiliation Agreement) at a price less than the Option Price (as adjusted pursuant to Section 5), the Option Price shall be equal to such lesser price; PROVIDED, further, that in no event shall the number of shares of Common Stock for which this Option is exercisable exceed 19.9% of the Issuer's issued and outstanding shares of Common Stock at the time of exercise without giving effect to any shares subject or issued pursuant to the Option. The number of shares of Common Stock that may be received upon the exercise of the Option and the Option Price is subject to adjustment as herein set forth. (b) In the event that any additional shares of Common Stock are issued or otherwise become outstanding after the date of this Agreement (other than pursuant to this Agreement and other than an event described in Section 5 hereof), the number of shares of Common Stock subject to the Option shall be increased so that, after such issuance, such number (including the number of shares theretofor issued pursuant to this Option) equals 19.9% of the number of shares of Common Stock then issued and outstanding without giving effect to any shares subject or issued pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to authorize Issuer to breach any provision of the Affiliation Agreement. 2. EXERCISE; CLOSING. (a) The Holder (as defined below) may exercise the Option, in whole or part, and from time to time, if, but only if, both an Initial Triggering Event (as defined below) and a Subsequent Triggering Event (as defined below) shall have occurred 2 prior to the occurrence of an Exercise Termination Event (as defined below), PROVIDED that the Holder shall have sent written notice of such exercise (as provided in subsection (f) of this Section 2) within 180 days following such Subsequent Triggering Event (or such later period as provided in Section 10). (b) Each of the following shall be an "EXERCISE TERMINATION EVENT": (i) the Effective Time (as defined in the Affiliation Agreement) of the Merger; (ii) termination of the Affiliation Agreement in accordance with the provisions thereof if such termination occurs prior to the occurrence of an Initial Triggering Event, except a termination by Grantee pursuant to Section VIII.A.1. of the Affiliation Agreement (provided that the breach by Issuer giving rise to the termination by Grantee under Section VIII.A.1. of the Affiliation Agreement was willful (a "Listed Termination")); or (iii) the passage of 18 months after termination of the Affiliation Agreement (or such later period as provided in Section 10) if such termination (A) follows or is concurrent with the occurrence of an Initial Triggering Event or (B) is a Listed Termination. The term "HOLDER" shall mean Grantee and any other person that shall become a holder of the Option in accordance with the terms of this Agreement. Notwithstanding anything to the contrary contained herein, this Agreement shall automatically terminate upon the proper termination of the Affiliation Agreement by Issuer pursuant to Section VIII.A.1. thereof. (c) The term "INITIAL TRIGGERING EVENT" shall mean any of the following events or transactions occurring after the date hereof: (i) Issuer or any Significant Subsidiaries (as defined in Rule 1-02 of Regulation S-X promulgated by the Securities and Exchange Commission (the "SEC")) (each an "ISSUER SUBSIDIARY"), without having received Grantee's prior written consent, shall have entered into an agreement to engage in an Acquisition Transaction (as defined below) with any person (the term "PERSON" for purposes of this Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), and the rules and regulations thereunder) other than Grantee or any of its Subsidiaries (each a "GRANTEE SUBSIDIARY") or the Board of Directors of Issuer shall have recommended that the stockholders of Issuer approve or accept any Acquisition Transaction (other than the Merger referred to in the Affiliation Agreement). For purposes of this Agreement, "ACQUISITION TRANSACTION" shall mean (x) a merger or consolidation, or any similar transaction, involving Issuer or any Significant Subsidiary of Issuer, (y) a purchase, lease or other acquisition or assumption of all or a substantial portion of the assets or deposits of Issuer or all or substantially all of the assets or deposits of any Significant Subsidiary of Issuer, (z) a purchase or other acquisition 2 3 (including by way of merger, consolidation, share exchange or otherwise) of beneficial ownership (the term "beneficial ownership" for purposes of this Agreement having the meaning assigned thereto in Section 13(d) of the Exchange Act, and the rules and regulations thereunder) of securities representing 10% or more of the voting power of Issuer or more than 10% of any Significant Subsidiary of Issuer; PROVIDED, however, that in no event shall any merger, consolidation, purchase or similar transaction involving only the Issuer and one or more of its wholly-owned Subsidiaries or involving only any two or more of such wholly-owned Subsidiaries, be deemed to be an Acquisition Transaction, if such transaction is not entered into in violation of the terms of the Affiliation Agreement; (ii) Issuer or any Issuer Subsidiary, without having received Grantee's prior written consent, shall have authorized, recommended, proposed or publicly announced its intention to authorize, recommend or propose, to engage in an Acquisition Transaction with any person other than Grantee or a Grantee Subsidiary or shall have authorized or engaged in, or announced its intention to authorize or engage in, any negotiations regarding an Acquisition Transaction with any person other than the Grantee or a Grantee Subsidiary, or the Board of Directors of Issuer shall have failed to recommend or shall have publicly withdrawn or modified, or publicly disclosed that, in the absence of the Option it would withdraw or modify, or publicly announced its intention to withdraw or modify, in any manner adverse to Grantee, its recommendation that the stockholders of Issuer approve the Merger; (iii) The shareholders of Issuer shall have voted and failed to approve the Merger and the plan of merger contained in the Affiliation Agreement at a meeting which has been held for that purpose or any adjournment or postponement thereof, or such meeting shall not have been held in violation of the Affiliation Agreement or shall have been canceled prior to termination of the Affiliation Agreement if, prior to such meeting (or if such meeting shall not have been held or shall have been canceled, prior to such termination), any person (other than the Grantee or a Grantee Subsidiary) shall have made a proposal to Issuer or its stockholders by public announcement or written communication that is or becomes the subject of public disclosure to engage in an Acquisition Transaction; (iv) (a) Any person other than Grantee, any Grantee Subsidiary or any Issuer Subsidiary acting in a fiduciary capacity in the ordinary course of its business, shall have acquired beneficial ownership or the right to acquire beneficial ownership of 10% or more of the then outstanding shares of Common Stock or (b) any group (the term "GROUP" having the meaning assigned in Section 13(d)(3) of the Exchange Act), other than a group of which the Grantee or any Grantee Subsidiary is a member, shall have been formed that beneficially owns 10% or more of the shares of Common Stock then outstanding; 3 4 (v) Any person other than Grantee or any Grantee Subsidiary shall have made a bona fide proposal to Issuer or its stockholders to engage in an Acquisition Transaction and such proposal shall have been publicly announced; (vi) After a proposal is made by a third party to Issuer or its stockholders to engage in an Acquisition Transaction or such third party states its intention to make such a proposal if the Affiliation Agreement terminates, Issuer shall have willfully breached any covenant or obligation contained in the Affiliation Agreement and such breach would entitle Grantee to terminate the Affiliation Agreement (without regard to the cure period provided for therein); or (vii) Any person other than Grantee or any Grantee Subsidiary, other than in connection with a transaction to which Grantee has given its prior written consent, shall have filed with any federal or state regulatory or governmental authority an application for approval or notice of intention to engage in an Acquisition Transaction. (d) The term "SUBSEQUENT TRIGGERING EVENT" shall mean either of the following events or transactions occurring after the date hereof: (i) The acquisition by any person or by a group other than Grantee, any Grantee Subsidiary or any Issuer Subsidiary acting in a fiduciary capacity in the ordinary course of its business, of beneficial ownership of 25% or more of the then outstanding Common Stock; or (ii) The occurrence of the Initial Triggering Event described in paragraph (i) of subsection (c) of this Section 2, except that references to 10% in clause (z) shall be 25%. (e) Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event (together, a "TRIGGERING EVENT"), it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option. (f) In the event the Holder is entitled to and wishes to exercise the Option (or any portion thereof), it shall send to Issuer a written notice (the date of which being herein referred to as the "NOTICE Date") specifying (i) the total number of shares it will purchase pursuant to such exercise and the aggregate purchase price as provided herein and (ii) a place and date not earlier than three business days nor later than 60 business days from the Notice Date for the closing of such purchase (the "CLOSING DATE"); PROVIDED that if prior notification to or approval of the Federal Reserve Board or any other regulatory agency is required in connection with such purchase, the Holder shall promptly file the required notice or application for approval and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or 4 5 periods shall have passed. Any exercise of the Option shall be deemed to occur on the Notice Date relating thereto. (g) At the closing referred to in subsection (f) of this Section 2, the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer and present and surrender this Agreement to Issuer at its principal executive offices; PROVIDED that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option. (h) At such closing subject to any regulatory notification and/or approval having been made or given and being in full force and effect, simultaneously with the delivery of immediately available funds as provided in subsection (g) of this Section 2, Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares of Common Stock purchasable hereunder, and the Holder shall deliver to Issuer this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement. (i) Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to certain provisions of an agreement between the registered holder hereof and Issuer and to resale restrictions arising under the Securities Act of 1933, as amended. A copy of such agreement is on file at the principal office of Issuer and will be provided to the holder hereof without charge upon receipt by Issuer of a written request therefor." It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "SECURITIES ACT"), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the Securities Act; (ii) the reference to the provisions of this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares of Common Stock delivered pursuant hereto have been sold or transferred in compliance with the provisions of this Agreement under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law. 5 6 (j) Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under subsection (f) of this Section 2 and the tender of the applicable purchase price in immediately available funds, the Holder shall be deemed, subject to the receipt of any necessary regulatory approvals, to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issue and delivery of stock certificates under this Section 2 in the name of the Holder or its permitted assignee, transferee or designee. 3. COVENANTS OF ISSUER. In addition to its other agreements and covenants herein, Issuer agrees: (i) that it shall at all times maintain, free from subscriptive or preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including (x) complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. Section 18a and regulations promulgated thereunder and (y) in the event, under the Bank Holding Company Act of 1956, as amended (the "BHCA") or the Change in Bank Control Act of 1978, as amended, or any state or other federal banking law, prior approval of or notice to the Federal Reserve Board or to any state or other federal regulatory authority is necessary before the Option may be exercised, cooperating fully with the Holder in preparing such applications or notices and providing such information to the Federal Reserve Board or such state or other federal regulatory authority as they may require) in order to permit the Holder to exercise the Option and Issuer to duly and effectively issue shares of Common Stock pursuant hereto; (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution; and (v) not to enter or agree to enter into any Acquisition Transaction unless the other party or parties thereto agree to assume in writing all of Issuer's obligations hereunder; PROVIDED that nothing in this Section 3 or elsewhere in this Agreement shall be deemed to authorize Issuer to breach any provision of the Affiliation Agreement. Notwithstanding any notice of revocation delivered pursuant to the proviso to Section 7(c), a Holder may require such other party or parties to perform Issuer's obligations under Section 7(a) unless such other party or parties are prohibited by law or regulation from such performance. 4. EXCHANGE; REPLACEMENT. This Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms "AGREEMENT" and "OPTION" as used herein include any Agreements and related Options for which this Agreement (and the Option granted 6 7 hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone. 5. ADJUSTMENTS. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalizations, combinations, subdivisions, conversions, exchanges of shares or the like, the type and number of shares of Common Stock purchasable upon exercise hereof shall be appropriately adjusted and proper provision shall be made so that, in the event that any additional shares of Common Stock are to be issued or otherwise become outstanding as a result of any such change (other than pursuant to an exercise of the Option), the number of shares of Common Stock that remain subject to the Option shall be increased so that, after such issuance and together with shares of Common Stock previously issued pursuant to the exercise of the Option (as adjusted on account of any of the foregoing changes in the Common Stock), it equals 19.9% of the number of shares of Common Stock then issued and outstanding. Whenever the number of shares of Common Stock purchasable upon exercise hereof is adjusted as provided in this Section 5, the Option Price shall be adjusted by multiplying the Option Price by a fraction, the numerator of which shall be equal to the number of shares of Common Stock purchasable prior to the adjustment and the denominator of which shall be equal to the number of shares of Common Stock purchasable after the adjustment. 6. REGISTRATION. Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within twelve (12) months (or such later period as provided in Section 10) of such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a shelf registration statement under the 1933 Act covering any shares issued and issuable pursuant to this Option and shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of any shares of Common Stock issued upon total or partial exercise of this Option ("OPTION SHARES") in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement promptly to become effective and then to remain effective for a period not in excess of 180 days from the day such registration statement first becomes effective or such shorter time as may be reasonably necessary, in the judgment of the Grantee or the Holder, to effect such sales or other dispositions. Grantee shall have the right to demand two such registrations. The Issuer shall bear the costs of such registrations (including, but not limited to, Issuer's attorneys' fees, printing costs and filing fees, except for underwriting discounts or commissions, brokers' fees). The foregoing notwithstanding, if, at the time of any request by Grantee for registration of Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing 7 8 underwriters, or, if none, the sole underwriter or underwriters, of such offering the inclusion of the Holder's Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; PROVIDED, however, that after any such required reduction of the number of Option Shares to be included in such offering for the account of the Holder shall constitute at least 25% of the total number of shares to be sold by the Holder and Issuer in the aggregate; and PROVIDED further, however, that if such reduction occurs, then the Issuer shall file a registration statement for the balance of such shares of Common Stock issuable pursuant to this Option as promptly as practical following such reduction and no reduction in the number of shares of Common Stock to be sold by the Holder shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in secondary offering underwriting agreements for the Issuer. Upon receiving any request under this Section 6 from any Holder, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 6, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall the number of registrations that Issuer is obligated to effect pursuant to this Section 6 be increased by reason of the fact that there shall be more than one Holder as a result of any assignment or division of this Agreement. 7. REPURCHASE OF OPTION AND/OR OPTION SHARES. (a) At any time after the occurrence of a Repurchase Event (as defined below), (i) at the request of the Holder, delivered prior to an Exercise Termination Event (or such later period as provided in Section 10), Issuer (or any successor thereto) shall repurchase the Option from the Holder at a price (the "OPTION REPURCHASE PRICE") equal to the amount by which (A) the Market/Offer Price (as defined below) exceeds (B) the Option Price, multiplied by the number of shares for which this Option may then be exercised and (ii) at the request of the owner of Option Shares from time to time (the "OWNER"), delivered prior to an Exercise Termination Event (or such later period as provided in Section 10), Issuer shall repurchase such number of the Option Shares from the Owner as the Owner shall designate at a price (the "OPTION SHARE REPURCHASE PRICE") equal to the Market/Offer Price multiplied by the number of Option Shares so designated. The term "MARKET/OFFER PRICE" shall mean the highest of (i) the price per share of Common Stock at which a tender offer or exchange offer therefor has been made after the date hereof, (ii) the price per share of Common Stock to be paid by any third party pursuant to an agreement with Issuer, (iii) the highest closing price per share of Common Stock as reported in the Wall Street Journal within the six-month period immediately preceding the date on which the Holder gives notice of the required repurchase of this Option or the Owner gives notice of the required repurchase of Option Shares, as the case may be, or (iv) in the event of a sale of all or a substantial portion of Issuer's assets, the sum of the price paid in such sale for such assets and the current market value of the remaining assets of Issuer as determined by a nationally recognized investment banking 8 9 firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Issuer, divided by the number of shares of Common Stock of Issuer outstanding at the time of such sale. In determining the Market/Offer Price, the value of consideration other than cash shall be determined by a nationally recognized investment banking firm mutually selected by the Holder or Owner, as the case may be, and reasonably acceptable to the Issuer. The costs of any such investment banking firm shall be paid equally by Issuer and such Holders or Owners. (b) The Holder or the Owner, as the case may be, may exercise its right to require Issuer to repurchase the Option and any Option Shares pursuant to this Section 7 by surrendering for such purpose to Issuer, at its principal office, a copy of this Agreement or certificates for Option Shares, as applicable, accompanied by a written notice or notices stating that the Holder or the Owner, as the case may be, elects to require Issuer to repurchase this Option and/or the Option Shares, as the case may be, in accordance with the provisions of this Section 7. As promptly as practicable and in any event within five business days after the surrender of the Option and/or certificates representing Option Shares and the receipt of such notice or notices relating thereto, Issuer shall deliver or cause to be delivered to the Holder the Option Repurchase Price and/or to the Owner the Option Share Repurchase Price or the portion thereof that Issuer is not then prohibited under applicable law and regulation from so delivering. (c) To the extent that Issuer is prohibited under applicable law or regulation, or as a consequence of administrative policy, from repurchasing the Option and/or the Option Shares in full, Issuer shall immediately so notify the Holder and/or the Owner and thereafter shall deliver or cause to be delivered, from time to time, to the Holder and/or the Owner, as appropriate, that portion of the Option Repurchase Price and the Option Share Repurchase Price, respectively, that it is no longer prohibited from delivering, in each case within five business days after the date on which Issuer is no longer so prohibited; PROVIDED, however, that if Issuer at any time after delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited under applicable law or regulation, or as a consequence of administrative policy, from delivering to the Holder and/or the Owner, as the case may be, the Option Repurchase Price or the Option Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to use its best efforts to obtain all required regulatory and legal approvals and to file any required notices as promptly as practicable in order to accomplish such repurchase), the Holder or Owner may revoke its notice of repurchase of the Option and/or the Option Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as appropriate, that portion of the Option Repurchase Price and/or the Option Share Repurchase Price that Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Holder, a new Agreement evidencing the right of the Holder to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Agreement was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Option Repurchase Price less the portion thereof theretofore delivered to the Holder and the denominator of which is the Option Repurchase Price, or (B) to the Owner, a certificate for the Option Shares it is then so prohibited from repurchasing. If an Exercise Termination Event shall have occurred prior to the date of the notice by Issuer described in the first sentence of this subsection (c), or shall be scheduled to occur at any time before the expiration of a period ending on the thirtieth day after 9 10 such date, the Holder shall nonetheless have the right to exercise the Option until the expiration of such 30-day period. (d) For purposes of this Section 7, a Repurchase Event shall be deemed to have occurred upon the occurrence of any of the following events or transactions after the date hereof: (i) the acquisition by any person (other than Grantee or any Grantee Subsidiary) of beneficial ownership of 50% or more of the then outstanding Common Stock; or (ii) the consummation of any Acquisition Transaction described in Section 2(c)(i) hereof, except that the percentages referred to in clause (z) shall be 50%. 8. SUBSTITUTE OPTION. (a) In the event that prior to an Exercise Termination Event, Issuer shall enter into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of Grantee's Subsidiaries, or engage in a plan of exchange with any person other than Grantee or one of Grantee's Subsidiaries, and Issuer shall not be the continuing or surviving corporation of such consolidation or merger or the acquiror in such plan of exchange, (ii) to permit any person, other than Grantee or one of its Subsidiaries, to merge into Issuer or be acquired by Issuer in a plan of exchange and Issuer shall be the continuing or surviving corporation, but, in connection with such merger or plan of exchange, the then outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other person or cash or any other property or the then outstanding shares of Common Stock shall after such merger or plan of exchange represent less than 50% of the outstanding voting shares and voting share equivalents of the merged or acquiring company, or (iii) to sell or otherwise transfer all or substantially all of its or any Significant Subsidiary's assets to any person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction shall make proper provision so that the Option shall, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option (the "SUBSTITUTE OPTION"), at the election of the Holder, of either (x) the Acquiring Corporation (as defined below) or (y) any person that controls the Acquiring Corporation. (b) The following terms have the meanings indicated: (1) "ACQUIRING CORPORATION" shall mean (i) the continuing or surviving person of a consolidation or merger with Issuer (if other than Issuer), (ii) the acquiring person in a plan of exchange in which Issuer is acquired, (iii) Issuer in a merger or plan of exchange in which Issuer is the continuing, surviving or acquiring person, and (iv) the transferee of all or substantially all of Issuer's assets or deposits. (2) "SUBSTITUTE COMMON STOCK" shall mean the common stock (or similar equity interest) issued by the issuer of the Substitute Option upon exercise of the Substitute Option. 10 11 (3) "ASSIGNED VALUE" shall mean the Market/Offer Price, as defined in Section 7. (4) "AVERAGE PRICE" shall mean the average closing price of a share of the Substitute Common Stock for the year immediately preceding the consolidation, merger or sale in question but in no event higher than the closing price of the shares of Substitute Common Stock on the day preceding such consolidation, merger or sale; PROVIDED that if Issuer is the issuer of the Substitute Option, the Average Price shall be computed with respect to a share of common stock issued by the person merging into Issuer or by any company which controls or is controlled by such person, as the Holder may elect. (c) The Substitute Option shall have the same terms as the Option; PROVIDED, that if the terms of the Substitute Option may not, for legal reasons, be the same as the Option, such terms shall be as similar as possible to the terms of the Option and in no event less advantageous to the Holder. The issuer of the Substitute Option shall also enter into an agreement with the then Holder or Holders of the Substitute Option in substantially the same form as this Agreement (after giving effect for such purpose to the provisions of Section 9), which agreement shall be applicable to the Substitute Option. (d) The Substitute Option shall be exercisable for such number of shares of Substitute Common Stock as is equal to the Assigned Value multiplied by the number of shares of Common Stock for which the Option was exercisable immediately prior to the event described in the first sentence of Section 8(a), divided by the Average Price. The exercise price of the Substitute Option per share of Substitute Common Stock shall then be equal to the Option Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock for which the Option was exercisable immediately prior to the event described in the first sentence of Section 8(a), and the denominator of which shall be the number of shares of Substitute Common Stock for which the Substitute Option is exercisable. (e) In no event, pursuant to any of the foregoing paragraphs, shall the Substitute Option be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise of the Substitute Option. In the event that the Substitute Option would be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise but for this clause (e), the issuer of the Substitute Option (the "SUBSTITUTE OPTION ISSUER") shall make a cash payment to Holder equal to the excess of (i) the value of the Substitute Option without giving effect to the limitation in this clause (e) over (ii) the value of the Substitute Option after giving effect to the limitation in this clause (e). This difference in value shall be determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be and reasonably acceptable to the Substitute Issuer, and all fees and expenses of such investment banking firm shall be shared equally. (f) Issuer shall not enter into any transaction described in subsection (a) of this Section 8 unless the Acquiring Corporation and any person that controls the Acquiring Corporation assume in writing all the obligations of Issuer hereunder. 11 12 9. REPURCHASE OF SUBSTITUTE OPTION AND/OR OPTION SHARES. (a) At the request of the holder of the Substitute Option (the "SUBSTITUTE OPTION HOLDER"), the Substitute Option Issuer shall repurchase the Substitute Option from the Substitute Option Holder at a price (the "SUBSTITUTE OPTION REPURCHASE PRICE") equal to the amount by which (i) the Highest Closing Price (as defined below) exceeds (ii) the exercise price of the Substitute Option, multiplied by the number of shares of Substitute Common Stock for which the Substitute Option may then be exercised, and at the request of the owner (the "SUBSTITUTE SHARE OWNER") of shares of Substitute Common Stock (the "SUBSTITUTE SHARES"), the Substitute Option Issuer shall repurchase the Substitute Shares at a price (the "SUBSTITUTE SHARE REPURCHASE PRICE") equal to the Highest Closing Price multiplied by the number of Substitute Shares so designated. The term "HIGHEST CLOSING PRICE" shall mean the highest closing price for shares of Substitute Common Stock within the six-month period immediately preceding the date the Substitute Option Holder gives notice of the required repurchase of the Substitute Option or the Substitute Share Owner gives notice of the required repurchase of the Substitute Shares, as applicable. (b) The Substitute Option Holder and the Substitute Share Owner, as the case may be, may exercise their respective right to require the Substitute Option Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to this Section 9 by surrendering for such purpose to the Substitute Option Issuer, at its principal executive office, the agreement for such Substitute Option (or, in the absence of such an agreement, a copy of this Agreement) and certificates for Substitute Shares accompanied by a written notice or notices stating that the Substitute Option Holder or the Substitute Share Owner elects to require the Substitute Option Issuer to repurchase the Substitute Option and/or the Substitute Shares, as the case may be, in accordance with the provisions of this Section 9. As promptly as practicable, and in any event within five business days after the surrender of the Substitute Option and/or certificates representing Substitute Shares and the receipt of such notice or notices relating thereto, the Substitute Option Issuer shall deliver or cause to be delivered to the Substitute Option Holder the Substitute Option Repurchase Price and/or to the Substitute Share Owner the Substitute Share Repurchase Price or, in either case, the portion thereof which the Substitute Option Issuer is not then prohibited under applicable law and regulation from so delivering. (c) To the extent that the Substitute Option Issuer is prohibited under applicable law or regulation, or as a consequence of administrative policy, from repurchasing the Substitute Option and/or the Substitute Shares in part or in full, the Substitute Option Issuer, following a request for repurchase pursuant to this Section 9, shall immediately so notify the Substitute Option Holder and/or the Substitute Share Owner and shall thereafter deliver or cause to be delivered, from time to time, to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, that portion of the Substitute Option Repurchase Price and/or the Substitute Share Repurchase Price, respectively, which it is no longer prohibited from delivering, in each case, within five business days after the date on which the Substitute Option Issuer is no longer so prohibited; PROVIDED, however, that if the Substitute Option Issuer at any time after delivery of a notice of repurchase pursuant to subsection (b) of this Section 9 is prohibited under applicable law or regulation, or as a consequence of administrative policy, from delivering to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option Repurchase Price and the Substitute Share Repurchase Price, respectively, in full (and the 12 13 Substitute Option Issuer shall use its best efforts to receive all required regulatory and legal approvals as promptly as practicable in order to accomplish such repurchase), the Substitute Option Holder and/or Substitute Share Owner may revoke its notice of repurchase of the Substitute Option or the Substitute Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, the Substitute Option Issuer shall promptly (i) deliver to the Substitute Option Holder or Substitute Share Owner, as appropriate, that portion of the Substitute Option Repurchase Price or the Substitute Share Repurchase Price that the Substitute Option Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new Substitute Option evidencing the right of the Substitute Option Holder to purchase that number of shares of the Substitute Common Stock obtained by multiplying the number of shares of the Substitute Common Stock for which the surrendered Substitute Option was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Substitute Option Repurchase Price less the portion thereof theretofore delivered to the Substitute Option Holder and the denominator of which is the Substitute Option Repurchase Price, or (B) to the Substitute Share Owner, a certificate for the Substitute Common Shares it is then so prohibited from repurchasing. If an Exercise Termination Event shall have occurred prior to the date of the notice by the Substitute Option Issuer described in the first sentence of this subsection (c), or shall be scheduled to occur at any time before the expiration of a period ending on the thirtieth day after such date, the Substitute Option Holder shall nevertheless have the right to exercise the Substitute Option until the expiration of such 30-day period. 10. EXTENSION. The period for exercise of certain rights under Sections 2, 6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights (provided and for so long as the Grantee or the Holder is using commercially reasonable efforts to obtain such regulatory approvals), and for the expiration of all statutory waiting periods; and (ii) to the extent necessary to avoid liability under Section 16(b) of the 1934 Act by reason of such exercise. 11.
