Exercise of Warrants. (a) The exercise of any Warrants represented by this Certificate is subject to the conditions set forth below in paragraph 4, "Compliance with U.S. Securities Laws." (b) Subject to compliance with all of the conditions set forth herein, the Holder shall have the right at any time and from time to time after June 30, 1998 to purchase from the Company the number of Shares which the Holder may at the time be entitled to purchase pursuant hereto, upon surrender of this Certificate to the Company at its principal office, together with the form of election to purchase attached hereto duly com pleted and signed, and upon payment to the Company of the Purchase Price. No Warrant may be exercised after 5:00 p.m., New York time, on the Expiration Date, after which time all Warrants evidenced hereby shall be void. (c) Payment of the Purchase Price shall be made in cash, by wire transfer of immediately available funds or by certified check or banker's draft payable to the order of the Com pany, or any combination of the foregoing. (d) The Warrants represented by this Certificate are exercisable at the option of the Holder, in whole or in part (but not as to fractional Shares). Upon the exercise of less than all of the Warrants evidenced by this Certificate, the Company shall forthwith issue to the Holder a new certificate of like tenor representing the number of unexercised Warrants. (e) Subject to compliance with all of the conditions set forth herein, upon surrender of this Certificate to the Company at its principal office, together with the form of election to purchase attached hereto duly completed and signed, and upon payment of the Purchase Price, the Company shall cause to be delivered promptly to or upon the written order of the Holder and in such name or names as the Holder may designate, a share certificate or share certificates for the number of whole Shares purchased upon the exercise of the Warrants. Such share certificate or share certificates representing the Shares shall be free of any restrictive legend. The Company shall ensure that no "stop transfer" or similar instruction or order with respect to the Shares purchased upon exercise of the Warrants shall be in effect at ChaseMellon Shareholders Services, IRG Plc or any suc cessor transfer agent for the Common Stock of the Company (the "Transfer Agent"). 2. Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares and shall not be required to issue scrip in lieu of fractional interests. Instead of any fractional Shares that would otherwise be issuable to the Holder, the Company shall pay to the Holder a cash adjustment in respect of such fractional interest in an amount equal to such fractional interest of the then-current Market Price per share (as defined in Section 7(f) hereof). 3. Payment of Taxes. The Company will pay all documen tary stamp taxes, if any, attributable to the issuance and delivery of the Shares upon the exercise of the Warrants; provided, however, that the Company shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any Warrant or any Shares in any name other than that of the Holder, which transfer taxes shall be paid by the Holder, and until payment of such transfer taxes, if any, the Company shall not be required to issue such Shares. 4. Compliance with U.S. Securities Laws. The Warrants have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "Securities Act"), or any other federal or state securities or blue sky laws. No offer, sale, transfer, pledge or other disposition (collectively, a "Disposal") of the Warrants represented by this Certificate may be made unless (i) registered under the Act and any applicable State securities or blue sky laws or (ii) the Company receives a written opinion of United States legal counsel in form and substance satisfactory to it to the effect that such Disposal is exempt from such registration requirements.. 5. Transfer of Warrants. (a) The Warrants shall be transferable only on the books of the Company maintained at the Company's principal office upon delivery of this Certificate with the form of assignment attached hereto duly completed and signed by the Holder or by its duly authorized attorney or representative, accompanied by proper evidence of succession, assignment or authority to transfer. The Company may, in its discretion, require, as a condition to any transfer of Warrants, a signature guarantee, which may be provided by a commercial bank or trust company, by a broker or dealer which is a member of the National Association of Securities Dealers, Inc., or by a member of a United States national securities exchange, The Securities and Futures Authority Limited in the United Kingdom, or The London Stock Exchange Limited in London, England. Upon any registration of transfer, the Company shall deliver a new warrant certificate or warrant certificates of like tenor and evidencing in the aggregate a like number of Warrants to the person entitled thereto in exchange for this Certificate, subject to the limitations provided herein, without any charge except for any tax or other governmental charge imposed in connection therewith. (b) Notwithstanding anything in this Certifi-cate to the contrary, neither any of the Warrants nor any of the Shares issuable upon exercise of any of the Warrants shall be transferable, except upon compliance by the Holder with any applicable provisions of the Securities Act and any applicable state securities or blue sky laws. 6. Exchange and Replacement of Warrant Certificates; Loss or Mutilation of Warrant Certificates. (a) This Certificate is exchangeable without cost, upon the surrender hereof by the Holder at the principal office of the Company, for new warrant certificates of like tenor and date representing in the aggregate the right to purchase the same number of Shares in such denominations as shall be designated by the Holder at the time of such surrender. Any transfer not made in such compliance shall be null and void and shall be given no effect hereunder. (b) Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Certificate and, in case of such loss, theft or destruction, of indemnity and security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of this Certificate, if mutilated, the Company will make and deliver a new warrant certificate of like tenor, in lieu thereof. 7. Initial Exercise Price; Adjustment of Exercise Price and Number of Shares. (a) The Warrants initially are exercisable at the Initial Exercise Price per Share, subject to adjustment from time to time as provided herein. No adjustments will be made for cash dividends, if any, paid to shareholders of record prior to the date on which the Warrants are exercised. (b) In case the Company shall at any time after the date of this Certificate (i) declare a dividend on the shares of Common Stock payable in shares of Common Stock, or (ii) subdivide or split up the outstanding shares of Common Stock, the amount of Shares to be delivered upon exercise of any Warrant will be appropriately increased so that the Holder will be entitled to receive the amount of Shares that such Holder would have owned immediately following such actions had such Warrant been exercised immediately prior thereto, and the Exercise Price in effect immediately prior to the record date for such dividend or the effective date for such subdivision shall be proportionately decreased, all effective immediately after the record date for such dividend or the effective date for such subdivision or split up. Such adjustments shall be made successively whenever any event listed above shall occur. (c) In case the Company shall at any time after the date of this Certificate combine the outstanding shares of Common Stock into a smaller number of shares the amount of Shares to be delivered upon exercise of any Warrant will be appropriately decreased so that the Holder will be entitled to receive the amount of Shares that such Holder would have owned immediately following such action had such Warrant been exercised immediately prior thereto, and the Exercise Price in effect immediately prior to the record date for such combination shall be proportionately increased, effective immediately after the record date for such combination. Such adjustment shall be made successively whenever any such combinations shall occur. (d) In the event that the Company shall at any time after the date of this Certificate (i) issue or sell any shares of Common Stock (other than the Shares) or securities convertible or exchangeable into Common Stock without consideration or at a price per share (or having a conversion price per share, if a security convertible into Common Stock) less than the Market Value per share of Common Stock (as defined in Section 7(f) hereof), or (ii) issue or sell options, rights or warrants to subscribe for or purchase Common Stock at a price per share less than the Market Price per share of Common Stock (as defined in Section 7(f) hereof), the Exercise Price to be in effect after the date of such issuance shall be determined by multiplying the Exercise Price in effect on the day immediately preceding the relevant issuance or record date, as the case may be, used in determining such Market Value or Market Price, by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding on such issuance or record date plus the number of shares of Common Stock which the aggregate offering price of the total number of shares of Common Stock so to be issued or to be offered for subscription or purchase (or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such Market Value or Market Price, as the case may be, and the denominator of which shall be the number of shares of Common Stock outstanding on such issuance or record date plus the number of additional shares of Common Stock to be issued or to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); such adjustment shall become effective immediately after the close of business on such issuance or record date; provided, however, that no such adjustment shall be made for the issuance of (s) options to purchase shares of Common Stock granted pursuant to the Company's employee stock option plans approved by shareholders of the Company (and the shares of Common Stock issuable upon exercise of such options) (provided that option exercise prices shall not be less than the Market Value of the Common Stock (as defined in Section 7(f) hereof) on the date of the grant of such options), (t) the Company's warrants to purchase shares of Common Stock (and the shares of Common Stock issuable upon exercise of such warrants), outstanding on the date hereof, (u) the Company's shares of Amended Series A, Cumulative Convertible Preferred Stock (and the shares of such Preferred Stock issued in lieu of dividend payments thereunder and the shares of Common Stock issuable upon conversion or redemption of such Preferred Stock), outstanding on the date hereof, or (v) the Company's shares of Amended Series B, Cumulative Convertible Preferred Stock (and the shares of Common Stock issued in lieu of dividend payments thereunder and the shares of Common Stock issuable upon conversion or redemption of such Preferred Stock), outstanding on the date hereof. In case such subscription price may be paid in a consideration, part or all of which shall be in a form other than cash, the value of such consideration shall be as determined reasonably and in good faith by the Board of Directors of the Company. Shares of Common Stock owned by or held for the account of the Company or any wholly-owned subsidiary shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever the date of such issuance is fixed (which date of issuance shall be the record date for such issuance if a record date therefor is fixed); and, in the event that such shares or options, rights or warrants are not so issued, the Exercise Price shall again be adjusted to be the Exercise Price which would then be in effect if the date of such issuance had not been fixed. (e) In case the Company shall make a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of its indebtedness, securities other than Common Stock or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends payable in Common Stock), the Exercise Price to be in effect after such date of distribution shall be determined by multiplying the Exercise Price in effect on the date immediately preceding the record date for the determination of the shareholders entitled to receive such distribution by a fraction, the numerator of which shall be the Market Price per share of Common Stock (as defined in Section 7(f) hereof) on such date, less the then-fair market value (as determined reasonably and in good faith by the Board of Directors of the Company of the portion of the assets, securities or evidences of indebtedness so to be distributed applicable to one share of Common Stock and the denominator of which shall be such Market Price per share of Common Stock, such adjustment to be effective immediately after the distribution resulting in such adjustment. Such adjustment shall be made successively whenever a date for such distribution is fixed (which date of distribution shall be the record date for such distribution if a record date therefor is fixed); and, if such distribution is not so made, the Exercise Price shall again be adjusted to be the Exercise Price which would then be in effect if such date of distribution had not been fixed. (f) For the purposes of any computation under this Section 7, the "Market Price per share" of Common Stock on any date shall be deemed to be the average of the closing bid price for the 20 consecutive trading days ending on the record date for the determination of the shareholders entitled to receive any rights, dividends or distributions described in this Section 7, and the "Market Value per share" of Common Stock on any date shall be deemed to be the closing bid price on the date of the issuance of the securities for which such computation is being made, as reported on the principal United States securities exchange on which the Common Stock is listed or admitted to trading or if the Common Stock is not then listed on any United States stock exchange, the average of the closing sales price on each such day during such 20 day period, in the case of the Market Price computation, or on such date of issuance, in the case of the Market Value computation, in the over-the-counter market as reported by the National Association of Securities Dealers' Automated Quotation System ("NASDAQ"), or, if not so reported, the average of the closing bid and asked prices on each such day during such 20 day period in the case of the Market Price computation, or on such date of issuance, in the case of the Market Value computation, as reported in the "pink sheets" published by the National Quotation Bureau, Inc. or any successor thereof, or, if not so quoted, the average of the middle market quotations for such 20 day period in the case of the Market Price computation, or on such date of issuance, in the case of the Market Value computation, as reported on the daily official list of the prices of stock listed on The London Stock Exchange Limited ("The Stock Exchange Daily Official List"). "Trading day" means any day on which the Common Stock is available for trading on the applicable securities exchange or in the applicable securities market. In the case of Market Price or Market Value computations based on The Stock Exchange Daily Official List, the Market Price or Market Value shall be converted into United States dollars at the then spot market exchange rate of pounds sterling (UK) into United States dollars as quoted by Chemical Bank or any successor bank thereto on the date of determination. If a quotation of such exchange rate is not so available, the exchange rate shall be the exchange rate of pounds sterling in United States dollars as quoted in The Wall Street Journal on the date of determination. (g) No adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $.02 in such price; provided that any adjustments which by reason of this Section 7(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further that such adjustment shall be made in all events (regardless of whether or not the amount thereof or the cumulative amount thereof amounts to $.02 (or more) upon the happening of one or more of the events specified in Sections 7(b), (c) or (i). All calculations under this Section 7 shall be made to the nearest cent. (h) If at any time, as a result of an adjustment made pursuant to Section 7(b) or (c) hereof, the Holder of any Warrant thereafter exercised shall become entitled to receive any shares of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Shares contained in this Section 7, and the provisions of this Certificate with respect to the Shares shall apply on like terms to such other shares. (i) In the case of (l) any capital reorganization of the Company, or of (2) any reclassification of the shares of Common Stock (other than a subdivision or combination of outstanding shares of Common Stock), or (3) any consolidation or merger of the Company, or (4) the sale, lease or other transfer of all or substantially all of the properties and assets of the Company as, or substantially as, an entirety to any other person or entity, each Warrant shall after such capital reorganization, reclassification of the shares of Common Stock, consolidation, or sale be exercisable, upon the terms and conditions specified in this Certificate, for the number of shares of stock or other securities or assets to which a holder of the number of Shares purchasable (immediately prior to the effectiveness of such capital reorganization, reclassification of shares of Common Stock, consolidation, or sale) upon exercise of a Warrant would have been entitled upon such capital reorganization, reclassification of shares of Common Stock, consolidation, merger or sale; and in any such case, if necessary, the provisions set forth in this Section 7 with respect to the rights thereafter of the Holder shall be appropriately adjusted (as determined reasonably and in good faith by the Board of Directors of the Company) so as to be applicable, as nearly as may reasonably be, to any shares of stock or other securities or assets thereafter deliverable on the exercise of a Warrant. The Company shall not effect any such consolidation or sale, unless prior to or simultaneously with the consummation thereof, the successor corporation, partnership or other entity (if other than the Company) resulting from such consolidation or the corporation, partnership or other entity purchasing such assets or the appropriate entity shall assume, by written instrument, the obligation to deliver to the Holder of each Warrant the shares of stock, securities or assets to which, in accordance with the foregoing provisions, such Holder may be entitled and all other obligations of the Company under this Certificate. For purposes of this Section 7(i) a merger to which the Company is a party but in which the Common Stock outstanding immediately prior thereto is changed into securities of another corporation shall be deemed a consolidation with such other corporation being the successor and resulting corporation. (j) Irrespective of any adjustments in the Exercise Price or the number or kind of shares purchasable upon the exercise of the Warrant, Warrant Certificates theretofore or thereafter issued may continue to express the same Exercise Price per share and number and kind of Shares as are stated on the Warrant Certificates initially issuable pursuant to this Warrant. (k) The Company may, in its sole discretion, at any time and from time to time before the Expiration Date, reduce the Exercise Price to any lower amount by notice to the Holders, in the manner provided in Section 12. 8. Notices to Warrant Holders. Nothing contained in this Certificate shall be construed as conferring upon the Holder the right to vote or to consent or to receive notice as a stock holder in respect of any meetings of stockholders for the election of directors or any other matter, or as having any rights whatsoever as a stockholder of the Company. If, however, at any time prior to the exercise or expiration of the Warrants, any of the following events shall occur: (i) the holders of shares of the Common Stock shall be entitled to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of current or retained earnings, as indicated by the accounting treatment of such dividend or dis tribution on the books of the Company; or (ii) the Company shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to sub scribe therefor; or (iii) a dissolution, liquidation or winding-up of the Company (other than in connection with a consoli dation or merger) or a sale of all or substantially all of its property, assets and business as an entirety shall be approved by the Company's Board of Directors; or (iv) there shall be any capital reorganization or reclassification of the capital stock of the Company (other than a change in the number of outstanding shares of Common Stock or a change in the par value of the Common Stock), or consolidation or merger of the Company with another entity; then, in any one or more of said events, the Company shall give written notice of such event at least fifteen (15) days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, convertible or exchangeable secur ities or subscription rights, options or warrants, or entitled to vote on such proposed dissolution, liquidation, winding-up or sale. Such notice shall specify such record date or the date of closing the transfer books, as the case may be. Failure to give such notice or any defect therein shall not affect the validity of any action taken in connection with the declaration or payment of any such dividend or distribution, or the issuance of any convertible or exchangeable securities or subscription rights, options or warrants, or any proposed dissolution, liquidation, winding-up or sale. 9. Reservation and Listing of Securities. (a) The Company covenants and agrees that at all times during the period after June 30, 1998, the Company shall reserve and keep available, free from preemptive rights, out of its authorized and unissued shares of Common Stock or out of its authorized and issued shares of Common Stock held in its treasury, solely for the purpose of issuance upon exercise of the Warrants, such number of Shares as shall be issuable upon the exercise of the Warrants. (b) The Company covenants and agrees that, upon exercise of the Warrants in accordance with their terms and payment of the Purchase Price, all Shares issued or sold upon such exercise shall not be subject to the preemptive rights of any stockholder and when issued and delivered in accordance with the terms of the Warrants shall be duly and validly issued, fully paid and non-assessable, and the Holder shall receive good and valid title to such Shares free and clear from any adverse claim (as defined in the applicable Uniform Commercial Code), except such as have been created by the Holder. (c) As long as the Warrants shall be outstanding, the Company shall use its reasonable efforts to cause all Shares issuable upon the exercise of the Warrants to be quoted by or listed on any national securities exchange or other securities listing service on which the shares of Common Stock of the Company are then listed. 10. Survival. All agreements, covenants, representations and warranties herein shall survive the execution and delivery of this Certificate and any investigation at any time made by or on behalf of any party hereto and the exercise, sale and purchase of the Warrants and the Shares (and any other securities or properties) issuable on exercise hereof. 11. Remedies. The Company agrees that the remedies at law of the Holder, in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms hereof, may not be adequate and such terms may, in addition to and not in lieu of any other remedy, be specifically enforced by a decree of specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise. 12. Registered Holder. The Company may deem and treat the registered Holder hereof as the absolute owner of this Certificate and the Warrants represented hereby (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise of the Warrants, of any notice, and of any distribution to the Holder hereof, and for all other purposes, and the Company shall not be affected by any notice to the contrary. 13.
