Such new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5.

NOTICE OF ADJUSTMENTS. Whenever any Warrant Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, the Warrant Price after giving effect to such adjustment and the number of shares then purchasable upon exercise of this Warrant, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the holder of this Warrant at the address specified in Section 10(d) hereof, or at such other address as may be provided to the Company in writing by the holder of this Warrant. 7.

(the "Company") up to ( ) shares of the Company's Common Stock, $0.10 par value [as defined in Section 7(a), the "Stock"] at a price of $8.33 per share (with adjustments provided for herein, the "Warrant Price") at any time until April 22, 2000, subject to the terms and conditions stated in this Warrant (the "Warrant"). 1.

The Company further warrants and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized and reserved a sufficient number of shares of Stock to provide for the exercise of the rights represented by this Warrant. 3. INVESTMENT REPRESENTATION The holder by accepting this Warrant represents that the Warrant is acquired for the holder's own account for investment purposes and not with a view to any offering or distribution and that the holder has no present intention of selling or otherwise disposing of the Warrant or the underlying shares of Stock. Upon exercise, the holder will confirm, in respect of securities obtained upon such exercise, that it is acquiring such securities for its own account and not with a view to any offering or distribution in violation of applicable securities laws. 4. ADJUSTMENTS TO PREVENT DILUTION a. If and whenever the Company shall issue or sell any shares of Stock for a consideration per share less than the Warrant Price in effect immediately prior to the time of such issue or sale, then upon such issue or sale, the Warrant Price shall be recalculated (and if applicable reduced, but in no event thereby increased) to a price (calculated to the nearest cent) determined by dividing (i) an amount equal to the sum of (aa) the number of shares of Stock outstanding immediately prior to such issue or sale multiplied by the then existing Warrant Price, and (bb) the consideration, if any, received by the Company upon such issue or sale by (ii) the total number of shares of Stock outstanding immediately after such issue or sale. For purposes of this Section 4, the phrase "Convertible Securities" (defined below) shall not include shares of Stock issued or issuable to officers, directors or employees of, or consultants to, the Company pursuant to a stock purchase or option plan or other employee or director stock incentive or - 3 - compensation programs approved by the Board of Directors. (1) If at any time the Company shall in any manner grant any options or rights to subscribe for or to purchase Stock or securities convertible into Stock ("Convertible Securities") or shall issue or sell any Convertible Securities and the price per share for which Stock is issuable upon the exercise of such rights or options or upon conversion or exchange of such Convertible Securities [determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the granting of such rights or options or for the issuance or sale of Convertible Securities, plus the minimum aggregate amount of additional consideration payable to the Company upon the exercise of such rights or options, plus, in the case of such Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Stock issuable upon the exercise of such rights or options or upon the conversion or exchange of such Convertible Securities] shall be less than the Warrant Price in effect immediately prior to the time of the granting of such rights or options or the issuance or sale of such Convertible Securities, then the total maximum number of shares of Stock issuable upon the exercise of such rights or options or upon conversion or exchange of such Convertible Securities shall (as of the date of granting of such rights or options or the issuance or sale of such Convertible Securities) be deemed to be outstanding and to have been issued for such price per share. No further adjustments of the Warrant Price shall be made upon the actual issue of such Stock or of such Convertible Securities upon exercise of such rights or options or upon the actual issue of such Stock upon conversion or exchange of such Convertible Securities. Unless a provision of any other paragraph of this Section 4 controls, if the price per share for which Stock is issuable upon exercise of such rights or options or upon conversion or exchange of such Convertible Securities shall change at any time, the Warrant Price then in effect shall forthwith be adjusted or readjusted to such Warrant Price as would have obtained had the adjustments made upon the issuance or sale of such rights, options or Convertible Securities been made upon the basis of (a) the issuance of the number of shares of Stock theretofore actually delivered (and the total - 4 - consideration received therefor) upon the exercise of such options or rights or upon the conversions or exchange of such Convertible Securities, and (b) the assumption that the remaining outstanding options, rights, or Convertible Securities were originally issued at the time of such change. On the expiration of any such option or right or the termination of any such right to convert or exchange such Convertible Securities, the Warrant Price then in effect shall forthwith be readjusted to such Warrant Price as would have obtained had the adjustments made upon the issuance or sale of such rights or options or Convertible Securities been made upon the basis of (a) the issuance of the number of shares of Stock theretofore actually delivered (and the total consideration received therefor) upon the exercise of such rights or options or upon the conversions or exchange of such Convertible Securities and (b) the issuance or sale of any such options, rights or Convertible Securities as remain outstanding after said expiration or termination. (2) If the Company shall declare a dividend, or make any further distribution upon any capital stock of the Company, payable in Stock or Convertible Securities, then any Stock or Convertible Securities (as the case may be) issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration; and in addition to the adjustment of the Warrant Price required by this Section 4(a), the number of shares of Stock issuable upon exercise of this Warrant shall be proportionately increased so that the holder upon exercise of this Warrant shall be entitled to receive the same number of shares of Stock which it would have received if it had exercised this Warrant in full immediately prior to the date for determining stockholders entitled to receive such dividend or distribution. (3) If any shares of Stock or Convertible Securities or any rights or options to purchase any such Stock or Convertible Securities shall be issued for cash, then the consideration received shall be deemed to be the amount received by the Company, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any shares of Stock or Convertible Securities or any rights or options to purchase any such Stock or Convertible Securities shall be issued for a consideration other than cash, the amount of the consideration other than - 5 - cash received by the Company shall be deemed to be the value of such consideration as determined by the Board of Directors of the Company, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. (4) If the Company shall take a record of the holders of its Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Stock or in Convertible Securities, or (ii) to subscribe for or purchase Stock or Convertible Securities, then for purposes of this Warrant such record date shall be deemed to be the date of the issue or sale of the shares of Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. b. If the Company shall declare a dividend upon any Stock of the Company payable otherwise than as a cash dividend paid out of current earnings, or in Stock or Convertible Securities, then the Warrant Price in effect immediately prior to the declaration of such dividend shall be reduced by an amount equal to the fair value of the dividend per share of the Stock outstanding at the time of such declaration as determined by the Board of Directors of the Company. Such reduction shall take effect as of the date on which a record is taken for the purpose of such dividend or, if a record is not taken, the date as of which the holders of Stock of record entitled to such dividend are to be determined. c. If the Company shall at any time subdivide its outstanding shares of Stock into a greater number of shares, then the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced, and the number of shares issuable upon exercise of this Warrant shall be proportionately increased; and conversely, in case the outstanding shares of Stock of the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased and the number of shares issuable proportionately reduced. d. Except as provided in paragraph (c) of this Section, if any capital reorganization or reclassification of the capital stock of the Company, or consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or of any successor corporation's property and assets to any other corporation or - 6 - corporations (any such corporation being included within the meaning of the term "successor corporation") shall be effected, then as a condition of such recapitalization, reclassification, consolidation, merger, or conveyance, lawful and adequate provision shall be made whereby the holder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions specified in this Warrant and in lieu of the shares of Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the right represented hereby, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Stock equal to the number of shares of such Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby had such recapitalization, reclassification, consolidation, merger or conveyance not taken place, and in any such case appropriate provisions shall be made with respect to the rights and interests of the holder of this Warrant to the end that the provisions hereof (including without limitation provisions for adjustment of the warrant price and of the number of shares purchasable upon the exercise of this warrant) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. Except as hereinafter provided, the Company shall not effect any consolidation or merger unless prior to the consummation thereof the successor corporation shall assume by written instrument executed and mailed to the holder at its address registered on the books of the Company the obligation to deliver to the holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to purchase. Notwithstanding the foregoing, in the event of a merger or consolidation in which the Company is not the surviving entity, if the Company concludes that it will be unable to satisfy the conditions of this paragraph without a material adverse effect on the terms of such proposed transaction, then the Company shall have the option, prior to or contemporaneously with the closing of such merger or consolidation, to purchase the Warrant from the holder at its then fair value, having regard to both the spread between the Warrant Price and the value of the consideration to be received in the transaction and the remaining term of the Warrant. The Company and the holder of the Warrant shall agree on such fair value or, in the event they are unable to agree, shall submit the question of fair value to binding arbitration before a single arbitrator sitting in Boston, Massachusetts, under the commercial rules of the American Arbitration Association (any cost of arbitration to be borne by the Company). - 7 - e. Upon any adjustment of the Warrant Price, then and in each such case the Company shall give written notice thereof, by first class mail, postage prepaid, addressed to the holder of this Warrant at its address registered on the books of the Company, which notice shall state the Warrant Price resulting from such adjustment and the increased or decreased, if any, number of shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 5. NOTICE OF REORGANIZATIONS, ETC. In case at any time: a. The Company shall declare any dividend upon its Stock whether payable in cash, property or Stock or make any distribution to the holders of its Stock; b. there shall be any capital reorganization, or reclassification of the capital stock of the Company, or consolidation or merger of the Company with another corporation; or c. there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company; then, in each one or more of said cases, the Company shall give at least 20 days' prior written notice, by first class mail, postage prepaid, addressed to the holder at its address registered on the books of the Company of (i) the date on which the books of the Company shall close or a record shall be taken for purposes of ascertaining which shareholders will be entitled to participate in such dividend or distribution or will be entitled to vote on such reclassification, reorganization, consolidation, merger, dissolution, liquidation or winding up, as the case may be; (iii) the date on which the vote shall be taken concerning such reclassification, reorganization, consolidation, merger, dissolution, liquidation or winding up, as the case may be; and (ii) the date on which such dividend or distribution is to be paid or such reclassification, liquidation or winding up, as the case may be, is to be effective. Such notice shall also specify the date as of which the holders of Stock of record shall participate in said dividend or distribution or shall be entitled to exchange their Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, dissolution, liquidation, or winding up, as the case may be. - 8 - 6. ISSUANCE OF ADDITIONAL STOCK The Company shall give to the holder at least 20 days' prior written notice, by first class mail, postage prepaid, addressed to the holder at its address registered on the books of the Company, of the record date for determining the holders of Stock who shall be granted rights as a class to subscribe for or to purchase, or any options for the purchase of, Stock or Convertible Securities, to the end that the holder may exercise its rights to acquire Stock under this Warrant, by delivery of an executed Exercise Notice in accordance with Section 1 prior to said record date, and may thereby receive the same rights as other holders of Stock on said record date. 7. MISCELLANEOUS a. As used herein the term "Stock" shall mean and include the Company's presently authorized Common Stock, $.10 par value, and stock of any other class into which such presently authorized Stock may hereafter be changed. For the purposes of Sections 4, 5, and 6, the term "Stock" shall also include any capital stock of any class of the Company hereafter authorized which shall not be limited to a fixed sum or percentage in respect of the rights of the holders thereof to participate in dividends or in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Company. b. This Warrant shall not entitle the holder to any voting rights or other rights as a stockholder of the Company, or to any other rights whatsoever except the rights herein expressed, and no cash dividend paid out of earnings or surplus or interest shall be payable or accrue in respect of this Warrant or the interest represented hereby or the shares which may be subscribed for any purchased hereunder until and unless and except to the extent that the rights represented by this Warrant shall be exercised. c. This Warrant is exchangeable, upon the surrender hereof at the office or agency of the Company, for new Warrants of like tenor representing in the aggregate the right to subscribe for and purchase the number of shares which may be subscribed for and purchased hereunder, each of such new Warrants to represent the right to subscribe for and purchase each number of shares as shall be designated by said holder at the time of such surrender. 8. TRANSFER AND REGISTRATION a. If any proposed transfer, in whole or in part, of this Warrant or the Stock issuable upon exercise of this - 9 - Warrant might reasonably involve a public offering of the same contrary to the investment representations in Section 3, the Company may require as a condition precedent to such transfer, an opinion of counsel, satisfactory to it, that the proposed transfer will not involve a public offering which is required to be registered under the Securities Act of 1933.
