Accordingly, in consideration of the mutual representations, warranties and covenants contained herein, the parties hereto agree as follows: SECTION 1 - THE MERGER 1.1 THE MERGER.

The Merger shall be effective at such time as the Merger Certificate is filed, as appropriate, with the Secretary of State with the State of Delaware in accordance with the DGCL or at such later time as is specified in such documents (the "Effective Time"). Immediately prior to the filing of the Merger Certificate, a closing (the "Closing") will be held at the offices of Palmer & Dodge LLP, One Beacon Street, Boston, Massachusetts (or such other place as the parties may agree) for the purpose of confirming satisfaction or waiver of all conditions to the Merger. Subject to satisfaction or waiver of each of the conditions specified in Sections 5, 6 and 7 hereof, the Closing shall take place within three business days after the last to occur of: (a) the day the Merger is approved by the stockholders of Pacific pursuant to Section 5.11; or (b) the day the issuance of the Merger Consideration (as defined below) is approved by the stockholders of Procept pursuant to Section 5.12; or on such other date as the parties may agree, but not later than June 30, 1999. The date on which the Closing occurs is referred to herein as the "Closing Date". 1.3 EFFECTS OF THE MERGER. The Merger shall have the effects set forth in Section 259, 260 and 261 of the DGCL. 2 1.4 CERTIFICATE OF INCORPORATION AND BYLAWS. The Certificate of Incorporation and Bylaws of Pacific, in each case as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation and Bylaws of the Surviving Corporation immediately after the Effective Time, until duly amended in accordance with applicable law. 1.5 DIRECTORS AND OFFICERS. The directors and officers of PAC immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation immediately after the Effective Time, each such officer and director to hold office in accordance with their respective terms. 1.6 CONVERSION OF STOCK. (a) For purposes of this Agreement, "Merger Consideration" means 2,755,000 shares of common stock, $0.01 par value per share, of Procept ("Procept Common Stock") reduced by the number of shares of Procept Common Stock which would be issued but for the terms of Section 262 of the DGCL in respect of Dissenting Shares (as defined in Section 1.8). (b) At the Effective Time, by virtue of the Merger and without any action on the part of Procept or Pacific: (i) All shares of Common Stock of Pacific, $0.02 par value per share (the "Pacific Common Stock") and all shares of Preferred Stock of Pacific, $25 par value per share, (the "Pacific Preferred Stock" collectively, with the Pacific Common Stock the "Pacific Stock") outstanding immediately prior to the Effective Time, other than Dissenting Shares (as defined in Section 1.8), shall be converted into and become the right to receive, (subject to the payment of cash for fractional shares as provided in Section 1.10) shares of Procept Common Stock in accordance with Section 1.6(c). (ii) All options and warrants to purchase Pacific Stock outstanding immediately prior to the Effective Time, shall be exercisable for that number of shares of Procept Common Stock which such option or warrant holder would have been entitled to receive if the underlying Pacific Stock had converted in the Merger, at an exercise price per share equal to the aggregate exercise price of the Pacific option or warrant exchanged divided by the number of shares of Procept Common Stock subject to the new option or warrant, and otherwise having the same terms and conditions as the Pacific option or warrant and otherwise in accordance with the terms of Section 5.19. (iii) All shares of Pacific Stock held at the Effective Time by Pacific as treasury stock or by a subsidiary of Pacific shall be canceled and no payment shall be made with respect thereto. (iv) All Dissenting Shares shall be dealt with in accordance with Section 1.8. (v) All shares of Common Stock of PAC, $0.01 par value per share, outstanding immediately prior to the Effective Time, shall be converted into the right to receive the same number of shares of the Surviving Corporation. 3 (c) The Merger Consideration shall be allocated among the holders of shares of Pacific Stock outstanding immediately prior to the Effective Time by allocating to each such holder of Pacific Stock outstanding at the Effective Time (other than the holders of Dissenting Shares) that number of shares of Procept Common Stock determined by multiplying the number of shares of Pacific Common Stock held by each such holder or issuable to a holder on conversion of Pacific Preferred Stock held by such holder by the Conversion Factor (as defined below). (d) "Conversion Factor" means the quotient obtained by dividing (i) 2,755,000 BY (ii) the number of shares of Pacific Common Stock either outstanding or issuable on conversion of outstanding shares of Pacific Preferred Stock immediately prior to the Effective Time. As of the date of this Agreement, based on the shares of Pacific Common Stock currently outstanding or issuable (i) on conversion of outstanding Pacific Preferred Stock and (ii) upon the closing of the Agreement and Plan of Merger between Pacific and Binary Therapeutics, Inc., the Conversion Factor is 0.11. (e) The Merger Consideration shall be adjusted in the event of any change in Procept Common Stock by reason of a stock splits, stock recapitalizations, combinations or subdivisions of the Common Stock of Procept, mergers or other exchanges of shares by operation of law or the like occurring after the date of this Agreement and before the Effective Time, such that, after the record date therefor the Merger Consideration shall be equal to the number and class of shares or other securities or property that would have been received in respect of a share of Procept Common Stock, as the case may be, if the Effective Time had occurred immediately prior to such record date. 1.7 CLOSING OF PACIFIC TRANSFER BOOKS. At the Effective Time, the stock transfer books of Pacific shall be closed and no transfer of Pacific Stock shall thereafter be made. If, after the Effective Time, certificates representing shares of Pacific Stock are presented to the Exchange Agent, they shall be canceled and exchanged for certificates representing Procept Common Stock. 1.8 PACIFIC DISSENTING SHARES. (a) Shares of Pacific Stock held by a stockholder who has properly exercised appraisal rights with respect thereto in accordance with Section 262 of the DGCL are referred to herein as "Dissenting Shares". Shares of Pacific Stock that constitute Dissenting Shares shall not be converted into Merger Consideration and shares of Procept Stock shall not be issued pursuant to Section 1.6(d) in exchange therefor. From and after the Effective Time, a stockholder who has properly exercised such appraisal rights shall no longer retain any rights of a stockholder of Pacific or the Surviving Corporation, except those provided under the DGCL. (b) Pacific shall give Procept (i) prompt notice of any written notices and demands under Section 262 of the DGCL with respect to any shares of capital stock of Pacific, any withdrawal of any such demands and any other instruments served pursuant to the DGCL and received by Pacific and (ii) the right to participate in all negotiations and proceedings with respect to any demands under Section 262 with respect to any shares of capital stock of Pacific. Pacific shall cooperate with Procept concerning, and shall not, except with the prior written 4 consent of Procept, voluntarily make any payment with respect to, or offer to settle or settle, any such demands. (c) In the event that a holder of Pacific Stock makes a demand under Section 262 of the DGCL the Merger Consideration shall be reduced by the number of shares of Procept Common Stock which would otherwise have been issued to such holder. 1.9 ISSUANCE OF PROCEPT CERTIFICATES. Prior to the Effective Time, Procept shall authorize one or more persons to act as Exchange Agent hereunder (the "Exchange Agent") and shall deposit with or for the account of the Exchange Agent certificates representing the number of shares or Procept Common Stock equaling the Merger Consideration and cash in lieu of fractional shares of Procept Common Stock. As soon as practicable after the Effective Time, (i) Pacific shall deliver to Procept a list of all record holders of Pacific Stock immediately prior to the Effective Time (the "Record Holders"), setting forth each stockholder's name, address and number of shares of Pacific Stock held prior to the Effective Time and such other information as may be reasonably requested by the Exchange Agent, certified by the Chief Executive Officer of Pacific (the "Stockholder List") and (ii) the Exchange Agent shall be instructed to mail to each Record Holder a form of letter of transmittal which shall specify instructions for use in effecting the surrender of Pacific Stock certificates in exchange for Merger Consideration. Upon the Exchange Agent's receipt of the letter of transmittal and any certificate held by a stockholder, each stockholder shall be entitled to receive a certificate representing that number of whole shares of Procept Common Stock into which the shares of Pacific Stock as set forth on the Stockholder List shall have been converted pursuant to the provisions of this Agreement. The shares of Pacific Stock outstanding immediately prior to the Effective Time (and any certificates representing such shares) shall be deemed canceled as of the Effective Time. Procept Common Stock into which Pacific Stock shall be converted in the Merger shall be deemed to have been issued at the Effective Time. If any Procept Common Stock certificates are to be issued in a name other than that in which the Pacific Stock was registered immediately prior to the Effective Time, it shall be a condition of such issuance that the person requesting such issuance shall deliver to the Exchange Agent all documents necessary to evidence and effect such transfer and shall pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of certificates for such shares of Procept Common Stock in a name other than that of the registered holder of the certificate or surrendered or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable. None of Procept, PAC or Pacific shall be liable to any stockholder for shares of stock or any cash in lieu of fractional interests delivered to a public official pursuant to applicable escheat or abandoned property laws. 1.10 NO FRACTIONAL SHARES. No certificates representing fractional shares of Procept Common Stock shall be issued upon the surrender for exchange of Pacific Stock certificates. No fractional interest shall entitle the owner to vote or to any rights of a security holder. In lieu of fractional shares, each stockholder who would otherwise have been entitled to a fractional share of Procept Common Stock, will receive from Procept at Closing an amount in cash (without interest) determined by multiplying such fraction by the fair market value of a share of Procept Common Stock. Such fair market value shall equal the mean of the daily high and low sales prices of the Procept Common Stock on the Nasdaq Small Cap Market, as reported by Nasdaq, averaged over the period of ten (10) trading days ending on the fifth trading day prior to the Closing Date. 5 SECTION 2 - REPRESENTATIONS AND WARRANTIES OF PAC Procept and PAC hereby make the following representations and warranties: 2.1 ORGANIZATION AND CORPORATE POWER.

Such adjustment shall be made successively whenever such an issuance is made. 10.6.2 For purposes of Subsection 10.6, the following Paragraphs (a) to (e) shall also be applicable: (a) No adjustment of the Dilution Value shall be made unless such adjustment would require a decrease of at least $.01; provided that any adjustments which by reason of this Paragraph 10.6.2(a) are not required to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with adjustments so carried forward, shall require a decrease of at least $.01 in the Dilution Value then in effect hereunder. (b) In case of (A) the sale or other issuance by Procept (including as a component of a unit) of any rights or warrants to subscribe for or purchase, or any options for the purchase of, Procept Common Stock or any securities convertible into or exchangeable for Procept Common Stock (such securities convertible, exercisable or exchangeable into Procept Common Stock being herein called "CONVERTIBLE SECURITIES"), or (B) the issuance by Procept, without the receipt by Procept of any consideration therefor, of any rights or warrants to subscribe for or purchase, or any options for the purchase of, Procept Common Stock or Convertible Securities, whether or not such rights, warrants or options, or the right to convert or exchange such Convertible Securities, are immediately exercisable, and the consideration per share for which Procept Common Stock is issuable upon the exercise of such rights, warrants or options or upon the conversion or exchange of such Convertible Securities (determined by dividing (x) the minimum aggregate consideration, as set forth in the instrument relating thereto, without regard to any antidilution or similar provisions contained therein for a subsequent adjustment of such amount, payable to Procept upon the exercise of such rights, warrants or options, plus the consideration received by Procept for the issuance or sale of such rights, warrants or options, plus, in the case of such Convertible Securities, the minimum aggregate amount, as set forth in the instrument relating thereto, without regard to any antidilution or similar provisions contained therein for a subsequent adjustment of such amount, of additional consideration, if any, other than such Convertible Securities, payable upon the conversion or exchange thereof, by (y) the total maximum number, as set forth in the instrument relating thereto, without regard to any antidilution or similar provisions contained therein for a subsequent adjustment of such amount, of shares of Procept Common Stock issuable upon the exercise of such rights, warrants or options or upon the conversion or exchange of such 47 Convertible Securities issuable upon the exercise of such rights, warrants or options) is less than either the Dilution Value or the Market Price of the Procept Common Stock as of the date of the issuance or sale of such rights, warrants or options, then such total maximum number of shares of Procept Common Stock issuable upon the exercise of sch rights, warrants or options or upon the conversion or exchange of such Convertible Securities (as of the date of the issuance or sale of such rights, warrants or options) shall be deemed to be "Procept Common Stock" for purposes of Subsection 10.6.1 and shall be deemed to have been sold for an amount equal to such consideration per share and shall cause an adjustment to be made in accordance with Subsection 10.6.1. (c) In case of the sale or other issuance by Procept of any Convertible Securities, whether or not the right of conversion or exchange thereunder is immediately exercisable, and the price per share for which Procept Common Stock is issuable upon the conversion or exchange of such Convertible Securities (determined by dividing (x) the total amount of consideration received by Procept for the sale of such Convertible Securities, plus the minimum aggregate amount, as set forth in the instrument relating thereto, without regard to any antidilution or similar provisions contained therein for a subsequent adjustment of such amount, of additional consideration, if any, other than such Convertible Securities, payable upon the conversion or exchange thereof, by (y) the total maximum number, as set forth in the instrument relating thereto without regard to any antidilution or similar provisions contained therein for a subsequent adjustment of such amount, of shares of Procept Common Stock issuable upon the conversion or exchange of such Convertible Securities) is less than either the Dilution Value or the Market Price of the Procept Common Stock as of the date of the sale or other issuance of such Convertible Securities, then such total maximum number of shares of Procept Common Stock issuable upon the conversion or exchange of such Convertible Securities (as of the date of the sale of such Convertible Securities) shall be deemed to be "Procept Common Stock" for purposes of Subsection 10.6.1 and shall be deemed to have been sold for an amount equal to such consideration per share and shall cause an adjustment to be made in accordance with Subsection 10.6.1. (d) In case Procept shall modify the rights of conversion, exchange or exercise of any of the securities referred to in Paragraphs (b) or (c) of this Subsection 10.6.2 or any other securities of Procept convertible, exchangeable or exercisable for shares of Procept Common Stock, for any reason other than an event that would require adjustment to prevent dilution, so that the consideration per share received by Procept after such modification is less than either the Dilution Value or the Market Price of the Procept Common Stock as of the date prior to such modification, then such securities, to the extent not theretofore exercised, converted or exchanged, shall be deemed to have expired or terminated immediately prior to the date of such modification and Procept shall be deemed for purposes of calculating any adjustments pursuant to this Section 10.6 to have issued such new securities upon such new terms on the date of modification. Such adjustment shall become effective as of the date upon which such modification shall take effect. On the expiration or cancellation of any such right, warrant or option or the termination or cancellation of any such right to convert or exchange any such Convertible Securities, the Dilution Value then in effect hereunder shall forthwith be readjusted to such Dilution Value as would have obtained (A) had the adjustments made upon the issuance or sale of such rights, warrants, options or Convertible Securities been made upon the basis of the issuance of only the number of shares of Procept Common Stock theretofore actually 48 delivered (and the total consideration received therefor) upon the exercise of such rights, warrants or options or upon the conversion or exchange of such Convertible Securities and (B) had adjustments been made on the basis of the Dilution Value as adjusted under clause (A) of this sentence for all transactions (which would have affected such adjusted Dilution Value) made after the issuance or sale of such rights, warrants, options or Convertible Securities. (e) In case of the sale of any shares of Procept Common Stock, any Convertible Securities, any rights or warrants to subscribe for or purchase, or any options for the purchase of, Procept Common Stock or Convertible Securities, the consideration received by Procept therefor shall be deemed to be the gross sales price therefor without deducting therefrom any expense paid or incurred by Procept or any underwriting discounts or commissions or concessions paid or allowed by Procept in connection therewith. In the event that any securities shall be issued in connection with any other securities of Procept, together comprising one integral transaction in which no specific consideration is allocated among the securities, then each of such securities shall be deemed to have been issued for such consideration as the Board of Directors of Procept determines in good faith; provided, however that if the Financial Advisor disagrees with such determination, Procept shall retain, at its own expense, an independent investment banking firm acceptable to the Financial Advisor for the purpose of obtaining an appraisal. 10.6.3 Notwithstanding any other provision hereof, no adjustment to the Dilution Value will be made: (a) upon the exercise of any of the options outstanding on the date hereof under Procept's existing stock option plans; or (b) upon the issuance or exercise of options which may hereafter be granted with the approval of Procept's Board of Directors, or exercised, under any employee benefit plan of Procept to officers, directors, consultants or employees, but only with respect to such options as are exercisable at prices no lower than the Closing Bid Price (or, if the prices referenced in the definition of Closing Bid Price cannot be determined, the Fair Market Value) of the Procept Common Stock as of the date of grant thereof; or (c) upon exercise of the Placement Options or the Advisory Options (as defined in Exhibits B and C to the Securities Purchase Agreement dated as of June 30, 1997 between Procept and certain stock purchasers), upon the exercise of the Class C Warrants of Procept currently outstanding or issuable pursuant to the exercise of the Placement and Advisory Options, as set forth in the PROCEPT DISCLOSURE SCHEDULE pursuant to Section 4.2 or upon the issuance or the conversion of any Class C Warrants approved in writing by the Financial Advisor; or (d) upon the issuance or sale of Procept Common Stock or Convertible Securities pursuant to the exercise of any rights, options or warrants to receive, subscribe for or purchase, or any options for the purchase of, Procept Common Stock or Convertible Securities, whether or not such rights, warrants or options were outstanding on the Effective Time or were thereafter issued or sold, provided that an adjustment was either made or not required to be made 49 in accordance with Subsection 10.6.1 in connection with the issuance or sale of such securities or any modification of the terms thereof; or (e) upon the issuance or sale of Procept Common Stock upon conversion or exchange of any Convertible Securities, provided that any adjustments required to be made upon the issuance or sale of such Convertible Securities or any modification of the terms thereof were so made, and whether or not such Convertible Securities were outstanding on the Effective Time or were thereafter issued or sold; or (f) upon the issuance of stock that may hereafter be purchased or sold with the approval of Procept's Board of Directors, under the 1993 Employee Stock Purchase Plan of Procept to officers, directors, consultants or employees, but only with respect to such shares as are purchased and/or sold in accordance with the current plan and at the prices no lower than eighty-five percent (85%) of the Closing Bid Price (or, if the prices referenced in the definition of Closing Bid Price cannot be determined, 85% of the Fair Market Value) of the Procept Common Stock as of the date of purchase and/or sale thereof; Paragraph 10.6.2(d) shall nevertheless apply to any modification of the rights of conversion, exchange or exercise of any of the securities referred to in this Subsection 10.6.3, except that Paragraph 10.6.2(d) shall not apply to any modification of the rights of conversion, exchange or exercise of the securities excepted by Paragraph (c) of this Subsection 10.6.3 that are required by the original terms of those respective instruments. 10.6.4 As used in this Section 10.6, the term "PROCEPT COMMON STOCK" shall mean and include Procept's Common Stock authorized at the Effective Time and shall also include any capital stock of any class of Procept thereafter 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 and in the distribution of assets upon the voluntary liquidation, dissolution or winding up of Procept. 10.6.5 Procept from time to time may decrease the Dilution Value by any amount for any period of time if the period is at least 20 days and if the decrease is irrevocable during the period. Whenever the Dilution Value is so decreased, Procept shall mail to the Rights Holders a notice of the decrease at least 15 days before the date the decreased Dilution Value takes effect, and such notice shall state the decreased Dilution Value and the period it will be in effect. Procept may make such decreases in the Dilution Value, in addition to those required or allowed by this Section 10, as shall be determined by it, as evidenced by a resolution of Procept's Board of Directors, to be advisable in order to avoid or diminish any income tax to holders of Procept Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. 10.7 CHANGE OF SHARES ADJUSTMENTS. In the event Procept shall, at any time or from time to time after the date hereof (i) issue any shares of Procept Common Stock as a stock dividend to the holders of Procept Common Stock or (ii) subdivide or combine the outstanding shares of Procept Common Stock into a greater or lesser number of shares (any such issuance, 50 subdivision or combination being herein called a "CHANGE OF SHARES"), then the Dilution Value shall be changed to a price (rounded to the nearest cent) determined by multiplying the Dilution Value in effect immediately prior to such Change of Shares by a fraction, the numerator of which shall be the number of shares of Procept Common Stock outstanding immediately prior to the Change of Shares and the denominator of which shall be the number of shares of Procept Common Stock outstanding immediately following the Change of Shares. 10.8 LIQUIDATION PUT. 10.8.1 The Rights Holder may require Procept to repurchase with cash any number (not to exceed such Rights Holder's Issuance Base Amount) of shares of Procept Common Stock then owned by such Rights Holder for 140% of the aggregate Dilution Value of such shares; provided, however, in the event of a Merger Transaction, any repurchase pursuant to this Section 10.8 may be paid in cash, property (valued as provided in Subsection 10.8.4) and/or securities (valued as provided in Subsection 10.8.4) of the entity surviving such Merger Transaction. 10.8.2 The Rights Holder covenants not to exercise the Liquidation Put unless a Liquidation Event has occurred. 10.8.3 The Rights Holder's Section 10 Rights shall be terminated to the pro rata extent of any exercise of such Rights Holder's Liquidation Put. 10.8.4 Any securities or other property to be delivered to the Rights Holder pursuant to this Section 10.8 shall be valued as follows: (a) Securities not subject to an investment letter or other similar restriction on free marketability: (i) If actively traded on the Stock Market, the value shall be deemed to be the Market Price of such securities as of the third day prior to the date of valuation. (ii) If not actively traded on the Stock Market, the value shall be the Fair Market Value of such securities. (b) For securities for which there is an active public market but which are subject to an investment letter or other restrictions on free marketability, the value shall be the Fair Market Value thereof, determined by discounting appropriately the Market Price thereof. (c) For all other securities, the value shall be the Fair Market Value thereof. 10.9 TRANSFER OF RIGHTS UNDER THIS SECTION 10. A Rights Holder's Section 10 Rights are not transferable until after April 9, 1999. The Rights Holder's Section 10 Rights are not transferable unless the transferee will be both the record and beneficial owner of the related Procept Common Stock and executes and delivers to Procept a counterpart to this Section 10 agreeing to be bound by the obligations of the Rights Holder hereunder. Any such transferee must provide his or her name and address, which name and address must be that of the beneficial owner, to Procept. Any transfer of Procept Common Stock and related Section 10 Rights must 51 be performed in accordance with applicable securities laws and regulations, and the transferor must provide Procept with an opinion of counsel, satisfactory to Procept, to that effect. Furthermore, no transfer of Section 10 Rights may be made relating to fewer shares of Procept Common Stock than the quotient of $25,000 divided by the Dilution Value. ANY PURPORTED TRANSFER OF SECTION 10 RIGHTS NOT IN COMPLIANCE WITH THIS SECTION 10.9 SHALL BE NULL AND VOID AND THE RIGHTS HOLDER SHALL FORFEIT ALL SECTION 10 RIGHTS RELATED TO SUCH TRANSFERRED PROCEPT COMMON STOCK. Upon, and to the extent of, any transfer of Procept Common Stock without the related Section 10 Rights, such related Section 10 Rights shall terminate. 10.10 ADJUSTMENTS TO ISSUANCE BASE AMOUNT. Upon the termination of any of the Rights Holder's Section 10 Rights, such Rights Holder's Issuance Base Amount shall be proportionally reduced. 10.11 NOTICES. 10.11.1 After each adjustment of the Dilution Value pursuant to Sections 10.2, 10.6, 10.7 and 10.15 Procept will promptly prepare a certificate signed by the Chief Executive Officer or President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary, of Procept setting forth: (i) the Dilution Value as so adjusted and (ii) a brief statement of the facts accounting for such adjustment. Procept will promptly file such certificate with the Transfer Agent and cause a brief summary thereof to be sent by ordinary first class mail to each Rights Holder at his or her last address as it shall appear on the Transfer Agent's record books. No failure to mail such notice nor any defect therein or in the mailing thereof shall affect the validity of such adjustment. The affidavit of an officer of the Transfer Agent or the Secretary or an Assistant Secretary of Procept that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts therein stated. The Transfer Agent may rely on the information in the certificate as true and correct and has no duty nor obligation independently to verify the amounts or calculations therein set forth. 10.11.2 After any adjustment in the Issuance Base Amount resulting from (i) any Reset Issuances, Semi-Annual Issuances, Dilution Issuances or Qualified Offering Issuance (ii) any Change in Shares or (iii) any termination of Section 10 Rights, Procept will promptly prepare a certificate signed by the Chief Executive Officer or President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary, of Procept setting forth: (x) the Issuance Base Amount immediately preceding and succeeding such adjustment and (y) a brief statement of the facts accounting for such adjustment. Procept will promptly file such certificate with the Transfer Agent and cause a brief summary thereof to be sent by ordinary first class mail to each Rights Holder at his or her last address as it shall appear on the Transfer Agent's record books. No failure to mail such notice nor any defect therein or in the mailing thereof shall affect the validity of such adjustment. The affidavit of an officer of the Transfer Agent or the Secretary or an Assistant Secretary of Procept that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts therein stated. The Transfer Agent may rely on the information in the certificate as true and correct and has no duty nor obligation independently to verify the amounts or calculations therein set forth. 52 10.12 TREASURY STOCK. Any Reset Issuance, Semi-Annual Issuance and Dilution Issuance shall be made with duly authorized, fully-paid and non-assessable shares of Procept Common Stock, in accordance with the DGCL, and shall be drawn from the treasury stock of Procept to the extent available. 10.13 MANDATORY TERMINATION OF SECTION 10 RIGHTS. At any time on or after the Reset Date, Procept may cause the Rights Holder's Section 10 Rights to be terminated if the Market Price of the Procept Common Stock shall have exceeded 300% of the then applicable Dilution Value as of the third business day prior to the date of notice of termination. No greater than 60 nor fewer than 20 days prior to the date of any such mandatory termination, notice by first class mail, postage prepaid, shall be given to the Rights Holders, addressed to such Rights Holders at their last addresses as they shall appear in the Transfer Agent's record books. Each such notice shall specify the date fixed for termination. Any notice which is mailed as herein provided shall be conclusively presumed to have been duly given by Procept on the date deposited in the mail, whether or not the Rights Holder receives such notice; and failure properly to give such notice by mail, or any defect in such notice, to any Rights Holders shall not affect the validity of the proceedings for the termination of any other Rights Holders' Section 10 Rights. 10.14 WAIVER OF SECTION 10 RIGHTS. With the written consent of Procept and the stockholders holding at least a majority of the issued and outstanding Procept Common Stock subject to Section 10 Rights or subject to Article VI Rights (as defined below), any provision of this Section 10 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended. Upon the effectuation of each such waiver or amendment, Procept shall promptly give written notice thereof to the Rights Holders, if any, who have not previously received notice thereof or consented thereto in writing. "Article VI Rights" are rights under a Subscription Agreement between a holder of Procept Common Stock (or such holder's predecessor in interest) and Procept granting rights referred to therein as "Article VI Rights", which rights are substantially the same as the Section 10 Rights 10.15 OPTIONAL EXCHANGE/RESET. 10.15.1 Upon the receipt of requisite approvals, if any, from the stockholders of Procept, the shares of Procept Common Stock acquired hereunder may be exchanged (the "EXCHANGE RIGHT"), at the option of each Rights Holder, upon the completion of a Qualified Offering (as defined below) into Qualified Offering Securities (as defined below). Upon exchange of their shares of Procept Common Stock, up to the Issuance Base Amount, the exchanging Rights Holders shall receive an amount of Qualified Offering Securities equal to the quotient of (i) the Issuance Base Amount being exchanged multiplied by the Dilution Value at the time of the Qualified Offering, divided by (ii) the Qualified Offering Securities Price (as defined below) multiplied by .75 (the "EXCHANGE PRICE"); provided, however, that in the event that the Exchange Price divided by the Underlying Procept Common Stock Amount (as defined below) is less than the greater of (a) $2.50 and (b) 50% of the average closing bid price of the Procept Common Stock for the twenty trading days immediately preceding the date of such exchange (the "FLOOR PRICE"), then the Exchange Price shall equal the Floor Price multiplied by the Underlying Procept Common Stock Amount. 53 As used herein the following terms shall have the following meanings: (a) "UNDERLYING PROCEPT COMMON STOCK AMOUNT" shall equal the number of shares of Procept Common Stock and Procept Common Stock underlying Convertible Securities included as part of each Qualified Offering Security but shall not include Procept Common Stock underlying warrants or options to purchase Procept Common Stock or to purchase a Convertible Security, whether or not such warrant or option contains a right to exercise such warrant or option by the delivery of shares deemed purchased thereunder, including, without limitation, by a cashless exercise. (b) "QUALIFIED OFFERING SECURITY" and "QUALIFIED OFFERING SECURITIES" shall mean the security or securities (whether they are Procept Common Stock, Convertible Securities, units of Procept Common Stock and/or Convertible Securities (as defined below) and warrants or other similar rights) issued or sold in the Qualified Offering (including any contractual rights granted to investors in connection with the Qualified Offering). (c) "QUALIFIED OFFERING" shall mean the sale or series of sales of equity securities of Procept next occurring after the Effective Time of this Offering, including, without limitation, Procept Common Stock, warrants, units of Procept Common Stock and warrants, other securities exchangeable, convertible or exercisable for Procept Common Stock, alone or in units, whether in a public offering or private placement, raising gross proceeds in excess of $2,500,000; excluding, however, at Procept's option, a firm commitment underwritten public offering. (d) "QUALIFIED OFFERING SECURITIES PRICE" shall mean the selling price to investors for each Qualified Offering Security. (e) "CONVERTIBLE SECURITY" and "CONVERTIBLE SECURITIES" shall mean any security convertible into or exchangeable for a share or shares of Procept Common Stock without the payment of any additional consideration in such conversion or exchange other than the delivery of such security, but shall not include a warrant or option to purchase Procept Common Stock or to purchase a Convertible Security, whether or not such warrant or option contains a right to exercise such warrant or option by the delivery of shares deemed purchased thereunder, including, without limitation, by a cashless exercise. 10.15.2 Upon and to the extent of any exchange into Qualified Offering securities as set forth in Section 10.15.1 above, the Section 10 Rights related to the exchanged Procept Common Stock shall terminate. 10.15.3 Upon the receipt of requisite approvals, if any, from the stockholders of Procept, holders who elect not to exchange their Procept Common Stock upon a Qualified Offering for Qualified Offering Securities, shall have the Dilution Value with respect to their Section 10 Rights adjusted (a "QUALIFIED OFFERING ADJUSTMENT EVENT") to equal the Exchange Price and shall receive an additional number of shares (the "QUALIFIED OFFERING ISSUANCE") of Procept Common Stock equal to the difference between (i) the quotient of (a) the Issuance Base Amount multiplied by the Dilution Value in effect prior to the date of adjustment divided by (b) the (x) Exchange Price divided by (y) the Underlying Procept Common Stock Amount, and (ii) 54 the Issuance Base Amount prior to the date of adjustment; provided, however, that no adjustment shall be made if it would result in an increase in the Dilution Value. Holders receiving Qualified Offering Issuance shall have Section 10 Rights with respect to such shares. SECTION 11 - MISCELLANEOUS 11.1 NOTICES.
