I. DEFINITIONS. ------------ Terms defined in the Agreement and not otherwise defined herein shall have the meanings assigned thereto in the Agreement. Certain terms used in this Warrant are specifically defined in Section 12 hereof. 2. EXERCISE OF WARRANT. -------------------- 2.1 IN GENERAL. This Warrant may be exercised in whole or in part by the holder hereof at any time or from time to time prior to its expiration by surrender of this Warrant, with the form of subscription at the end hereof duly executed by such holder, to the Company at its principal office, accompanied by payment, by certified or official bank check payable to the order of the Company or by wire transfer to its account in the amount obtained by multiplying the number of shares of Common Stock for which this Warrant is then being exercised by the Exercise Price then in effect; PROVIDED, HOWEVER, that the holder hereof shall have the right, at its election, in lieu of delivering the Exercise Price in cash, to instruct the Company in the form of subscription to retain, in payment of the Exercise Price, a number of shares of Common Stock (the "Payment Shares") equal to the quotient of (i) the aggregate Exercise Price of the shares as to which this Warrant is then being exercised divided by (ii) the "Average Closing Price" as of the date of exercise and to deduct the number of Payment Shares from the shares to be delivered to the holder hereof. "Average Closing Price" means, as of any date, (x) if shares of Voting Common Stock are listed on a national securities exchange, the average of the closing sales prices therefor on the largest securities exchange on which such shares are traded on the last ten (10) trading days before such date, (y) if such shares are listed on the NASDAQ National Market System but not on any national securities exchange, the average of the closing sales prices therefor on the NASDAQ National Market System on the last ten (10) trading days before such date or (z) if such shares are not listed on either a national securities exchange or the NASDAQ National Market System, the average of the sales prices therefor on the last twenty (20) trading days before such date. In the event the Warrant is not exercised in full, the Company, at its expense, will forthwith issue and deliver to or upon the order of the holder hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof or as such holder (upon payment by such holder of any applicable transfer taxes) may request, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of such shares (without giving effect to any adjustment therein) for which this Warrant shall have been exercised. 2.2 Intentionally Omitted. 2.3 CONFLICT WITH OTHER LAWS. Any other provisions hereof to the contrary notwithstanding, no Bank Affiliate shall be entitled to exercise the right under this Warrant to 2 3 purchase any share or shares of Common Stock if, under any law or under any regulation, rule or other requirement of any governmental authority at any time applicable to such Bank Affiliate, (a) as a result of such purchase, such Bank Affiliate would own, control or have power to vote a greater quantity of securities of any kind than the Bank Affiliate shall be permitted to own, control or have power to vote or (b) such purchase would not be permitted. For purposes of this Section 2.3, a written certification of the Bank Affiliate exercising the Warrant, delivered upon surrender of the Warrant pursuant to the Agreement, to the effect that the Bank Affiliate is legally entitled to exercise its right under this Warrant to purchase securities and that such purchase will not violate the prohibitions set forth in the preceding sentence, shall be conclusive and binding upon the Company and shall obligate the Company to deliver certificates representing the shares of Common Stock so purchased in accordance with the other provisions hereof and shall relieve the Company of any liability under this Section 2.3. 2.4 TERMINATION OF THE WARRANT. This Warrant shall terminate upon the earlier to occur of (i) August 29, 2003 and (ii) the exercise in full. 3. REGISTRATION RIGHTS. -------------------- The holder of this Warrant has the right to cause the Company to register shares of Warrant Stock, and any shares issued upon exercise hereof, under the Securities Act and any blue sky or securities laws of any jurisdictions within the United States at the time and in the manner specified in the Registration Rights Agreement. 4. DELIVERY OF STOCK CERTIFICATES ON EXERCISE. ------------------------------------------- As soon as practicable after the exercise of this Warrant in full or in part, any in any event within twenty (20) days thereafter, the Company at its expense (including the payment by or of any applicable issue taxes) will cause to be issued in the name of and delivered to the holder hereof, or as such holder (upon payment by such holder of any applicable transfer taxes) may direct, a certificate or certificates for the number of fully paid and non-assessable shares of Common Stock (or Other Securities) which such holder shall be entitled to receive on such exercise, together with any other stock or other securities and property (other than cash) which such holder is entitled to receive upon exercise. 5. ADJUSTMENT FOR DIVIDEND, DISTRIBUTION AND RECLASSIFICATIONS. ------------------------------------------------------------ In case at any time or from time to time the holders of Common Stock shall have received or (on or after the record date fixed for the determination of shareholders eligible to receive) shall have become entitled to receive, without payment therefor: (a) other or additional stock or other certificates or property (other than cash) by way of dividend; or (b) other or additional stock or other securities or property (other than cash) by 3 4 way of spin-off, split-up, reclassification, recapitalization, combination of shares or similar corporate restructuring; OTHER THAN additional shares of Common Stock issued in a stock split or other reclassification, recapitalization or similar corporate restructuring of the Company's Common Stock (adjustment in respect of which are provided for in Section 7.1 hereof), then and in each such case the holder of this Warrant, on the exercise hereof as provided in Section 2 hereof, shall be entitled to receive the amount of stock and other securities and property (other than cash) which such holder would have received prior to, or would have held on the date of, such exercise if on the date hereof he had been the holder of record of the number of shares of Common Stock called for on the face of this Warrant and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and all such other or additional stock and other securities and property (other than cash) receivable by such holder as aforesaid during such period, giving effect to all further adjustments called for during such period by Sections 6 and 7 hereof. The Company hereby agrees that it will at all times reserve and keep available for such holder, solely for delivery upon the exercise of this Warrant, any distribution to which such holder is entitled under this Section 5. 6. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC. ---------------------------------------------------------- 6.1 CERTAIN ADJUSTMENTS. In case at any time or from time to time, the Company shall (i) effect a capital reorganization, reclassification or recapitalization, (ii) consolidate with or merge into any other Person or (iii) transfer all or substantially all of its properties or assets to any other Person under any plan or arrangement contemplating the dissolution of the Company, then in each such case, the holder of this Warrant, on the exercise hereof as provided in Section 2 hereof at any time after the consummation of such reorganization, reclassification, recapitalization, consolidation, merger or transfer, or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or effective date, the stock and other securities and property (including cash) to which such holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if such holder had so exercised this Warrant immediately prior thereto, all subject to further adjustment thereafter as provided in Section 5 and 7 hereof. 6.2 CONTINUATION OF TERMS. Upon any reorganization, reclassification, recapitalization, consolidation, merger or transfer referred to in this Section 6, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and Other Securities and property receivable on the exercise of this Warrant after the consummation of such reorganization, reclassification, recapitalization, consolidation or merger, as the case may be, and shall be binding upon the issuer of any such stock or Other Securities, including, in the case of any such transfer, the Person acquiring all or substantially all of the properties or assets of the Company, whether or not such Person shall have expressly assumed the terms of this Warrant as provided in Section 8 hereof. 4 5 7. ADJUSTMENTS FOR ISSUANCE OF COMMON STOCK AND AMOUNT OF OUTSTANDING COMMON STOCK. --------------------------------------- 7.1 IN GENERAL. If at any time there shall occur any stock split, stock dividend, reverse stock split or other subdivision, reclassification, recapitalization, recombination of shares or similar corporate restructuring of the Company's Common Stock, any rights offering by the Company to its existing stockholders or any issuance by the Company of Additional Shares of Common Stock upon the exercise of Convertible Securities (each as defined in Section 7.2 hereof) granted before the consummation of the G&M Merger, other than any such shares issued upon the exercise of options granted to Thomas A. Trantum before August 30, 1991 (each, a "Stock Event"), then the number of shares of Common Stock to be received by the holder of this Warrant shall be appropriately adjusted such that the proportion of the number of shares issuable hereunder to the total number of outstanding shares of the Company (calculated on a Fully-Diluted Basis) prior to such Stock Event is equal to the proportion of the number of outstanding shares of the Company after such Stock Event (calculated on a Fully-Diluted Basis). No adjustment to the Exercise Price shall be made in connection with any adjustment of the number of shares of Common Stock receivable upon exercise of this Warrant, except that the Exercise Price shall be proportionately increased or decreased upon the occurrence of any event provided for in this Section 7.1 so that the aggregate Exercise Price for all shares of Common Stock covered hereby shall remain unchanged. 7.2 ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. If at any time the Company shall issue or sell (i) any Additional Shares of Common Stock in exchange for consideration in an amount per Additional Share of Common Stock less than the Fair Market Value Per Share of Common Stock at the time the Additional Shares of Common Stock are issued or sold or (ii) any Convertible Securities having an exercise price or Conversion Price in an amount per share of Common Stock less than the Fair Market Value Per Share of Common Stock at the time of such issuance or sale, then the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product obtained by multiplying the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such issuance or sale by a fraction (a) the numerator of which shall be the number of shares of Common Stock outstanding immediately after such issuance or sale (assuming the conversion or exercise of all such Convertible Securities) and (b) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance or sale plus either (x) the number of shares which the aggregate offering price of the total number of such Additional Shares of Common Stock would purchase at the then Fair Market Value Per Share or (y) the number of shares of Common Stock which could be purchased if the exercise price of such Convertible Security or the Conversion Price of such Convertible Security (as applicable) were set at the then Fair Market Value Per Share. Thereupon, the Exercise Price shall be correspondingly reduced so that the aggregate Exercise Price for all shares of Common Stock covered hereby shall remain unchanged. No adjustments shall be made upon the exercise or conversion of Convertible Securities. For purposes of this paragraph, (i) the term "Additional Shares of Common Stock" means any shares of Common Stock issued by the Company after the Closing Date other than Warrant Stock or stock issuable upon the exercise of options granted 5 6 to Thomas A. Trantum, before August 30, 1991, (ii) the term "Convertible Securities" means all options, warrants or securities exercisable for, all rights to subscribe for, and all securities which are convertible into to exchangeable for, Common Stock and (iii) the term "Conversion Price" means, with respect to any Convertible Security, the price paid for such Convertible Security divided by the number of shares of Common Stock into which such Convertible Security is convertible on the date of issuance of such Convertible Security. 8. NO DILUTION OR IMPAIRMENT. -------------------------- The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder of this Warrant hereunder. Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of stock receivable on the exercise of the Warrant above the amount payable therefor on such exercise, (ii) will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of stock on the exercise of the Warrant from time to time outstanding, (iii) will not issue any capital stock of any class which is preferred as to dividends or as to the distribution of assets upon voluntary or involuntary dissolution, liquidation or winding up, unless the rights of the holders thereof shall be limited to a fixed sum or percentage of par value in respect of participation in dividends and in any such distribution of assets and (iv) will not transfer all or substantially all of its properties and assets to any other entity (corporate or otherwise), or consolidate with or merge into any other entity or permit any such entity to consolidate with or merge into the Company (if the Company is not the surviving entity), unless such other entity shall expressly assume in writing and will be bound by all the terms of this Warrant and the Agreement. If any event occurs as to which the provisions of Sections 5, 6 or 7 hereof are strictly applicable and the application thereof would not, in the good faith judgment of the Board of Directors of the Company, fairly protect the purchase rights of the Warrants in accordance with the essential intent and principles of such provisions, then such Board shall make such adjustments in the application of such provisions, in accordance with such essential intent and principles, as shall be reasonably necessary, in the good faith opinion of such Board, to protect such purchase rights as aforesaid, but in no event shall any such adjustment have the effect of increasing the Exercise Price or decreasing the number of shares of Common Stock subject to purchase upon exercise of this Warrant. Nothing contained in this Warrant shall prohibit the Company from issuing or selling securities in the future. 9. ACCOUNTANTS' CERTIFICATE AS TO ADJUSTMENTS. ------------------------------------------- In each case of any event that may require any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of this Warrant, the Company at its expense will promptly prepare a certificate setting forth such adjustment or readjustment and showing, in detail, the facts upon which any such adjustment or readjustment 6 7 is based, including a statement of (i) the number of shares of the Company's Common Stock then outstanding on a Fully-Diluted Basis, and (ii) the number of shares of Common Stock (or Other Securities) to be received upon exercise of this Warrant (A) immediately prior to such adjustment or readjustment and (B) as adjusted and readjusted (if required by Section 7) on account thereof. The Company will forthwith mail a copy of each such certificate to each holder of a Warrant and will, on the written request at any time of any holder of a Warrant, furnish to such holder a like certificate setting forth the calculations used to determine such adjustment or readjustment. At its option, the holder of a Warrant may confirm the adjustment noted on the certificate by causing such adjustment to be computed by an independent certified public accountant at the expense of the Company. The cost of any such confirmation shall be borne (x) by the Company, if the computation of such independent certified public accountant indicates that the adjustment noted on the Company's certificate was in any respect incorrect to the detriment of the holders, and (y) otherwise, by the holder requesting such confirmation. 10. NOTICES OF RECORD DATE. ----------------------- In the event of: (a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution (including, without limitation, any distribution that may arise as a result of a spin-off, split-up, reclassification, recapitalization, combination of shares or similar corporate restructuring), or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right; (b) any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any transfer of all or substantially all the assets of the Company to or any consolidation or merger of the Company with or into any other Person; (c) any voluntary or involuntary dissolution, liquidation or winding-up of the Company; or (d) any proposed issuance or grant by the Company of any shares of stock of any class or any other securities, or any right or option to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities (other than the issuance of Common Stock on the exercise of this Warrant), then, and in each such event, the Company will mail or cause to be mailed to the holder of this Warrant a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, (ii) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is to take place and the time, if any, to be fixed, as of which the holders of record of Common Stock (or 7 8 Other Securities) shall be entitled to exchange their shares of Common Stock (or Other Securities) for securities or other property deliverable on such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up and (iii) the amount and character of any stock or other securities, or rights or options with respect thereto, proposed to be issued or granted, the date of such proposed issue or grant and the persons or class of persons to whom such proposed issue or grant is to be offered or made. Such notice shall be mailed at least twenty (20) days prior to the date specified in such notice on which any such action is to be taken. 11. RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANT. ----------------------------------------------------- The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of the Warrant, a number of shares of Convertible Non-Voting Common Stock equal to the total number of shares of Convertible Non-Voting Common Stock from time to time issuable upon exercise of this Warrant and the number of Other Securities which at any time may be issuable hereunder, and, from time to time, will take all steps necessary to amend its Certificate of Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of the Warrant and upon the conversion of shares of one class of Common Stock into shares of the other class of Common Stock, as provided in its Certificate of Incorporation. 12.
