(i) Redeem, purchase or otherwise acquire for value any share or shares of Series A Preferred Stock or Common Stock, provided, however, that this restriction shall not apply to the repurchase of shares of Common Stock held by employees, consultants, directors or officers of the Company which are subject to stock repurchase agreements under which the Company has the right to repurchase such shares at the original purchase price per share in the event of termination of employment;

(ii) Authorize or issue, or obligate itself to authorize or issue, any other equity security senior to or on a parity with the Series A Preferred Stock as to dividends or liquidation preferences;

(v) Make any material change in the nature of its business as carried on at the date hereof or as contemplated in written materials delivered to the Purchaser at the time of its acquisition of the Shares; or

(vi) Sell, assign, license or otherwise dispose of or voluntarily part with control of any of the Company’s intellectual property rights to any individual, corporation, partnership, joint venture, trust or unincorporated organization or a government or any agency or political subdivision thereof.

7.9 Termination of Covenants. The covenants contained in subsections 7.1 through 7.8 above shall terminate, and be of no further force or effect, upon the effective date of a Registration Statement (as defined in subsection 8.1 hereto) covering the first fully underwritten, firm commitment public offering by the Company of its Common Stock, resulting in aggregate net proceeds to the Company of at least $15,000,000 (excluding underwriting discounts and commissions) and a per share sales price of at least $7.00 (such amount to be equitably adjusted upon the occurrence of any stock split, stock dividend, combination, reclassification or other similar event) (the “Initial Public Offering”).

“Registrable Shares” means (i) the shares of Common Stock issued or issuable upon conversion of the Shares, (ii) any shares of Stock purchased by the Purchaser on exercise of its pre-emption rights under Section 7.6 hereof and (iii) any other shares of Common Stock of the Company issued in respect of such shares (because of stock splits, stock dividends, reclassifications, recapitalizations, or similar events). Wherever reference is made in this Agreement to a request or consent of holders of a certain percentage of Registrable Shares, or to a number or percentage of Registrable Shares held by a Stockholder, such reference shall include shares of Common Stock issuable upon conversion of the Shares even though such conversion has not yet been effected.

“Registration Statement” means a registration statement filed by the Company with the Commission for a public offering and sale of securities of the Company (other than a registration statement on Form S-8 or Form S-4, or their successors, or any other form for a limited purpose, or any registration statement covering only securities proposed to be issued in exchange for securities or assets of another corporation).

(b) At any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to secondary offerings), a Stockholder or Stockholders holding in the aggregate Registrable Shares having a market value of $1,000,000, may request the Company, in writing, to effect the registration on Form S-3 (or any successor form), of all or such portion of the Registrable Securities as the holder or holders shall specify. Upon receipt of any such request, the Company shall promptly give written notice of such proposed registration to all Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within thirty (30) days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Stockholders may request in such notice of election. Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration on Form S-3 (or any successor form) of all Registrable Shares which the Company has been so requested to register.

(c) The Company shall not be required to effect more than two (2) registrations pursuant to paragraph (a) above.

(a) Whenever the Company proposes to file a Registration Statement, it will, prior to such filing, give written notice to all Stockholders of its intention to do so and, upon the written request of a Stockholder or Stockholders given within twenty (20) days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its best efforts to cause all Registrable Shares which the Company has been requested to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Stockholder(s); provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this subsection 8.4 without obligation to any Stockholder.

(b) In connection with any offering under this subsection 8.4 involving an underwriting, the Company shall not be required to include any Registrable Shares in such

underwriting unless the holders thereof accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it, and then only in such quantity as will not, in the opinion of the underwriters, jeopardize the success of the offering by the Company. If in the opinion of the managing underwriter the registration of all, or part of, the Registrable Shares which the holders have requested to be included would materially and adversely affect such public offering, then the Company shall be required to include in the underwriting only that number of Registrable Shares, if any, which the managing underwriter believes may be sold without causing such adverse effect. In the event of such a reduction in the number of shares to be included in the underwriting, the holders of Registrable Shares who have requested registration shall participate in the underwriting pro rata based upon their total ownership of Registrable Shares (or in any other proportion as agreed upon by such holders) and if any holder would thus be entitled to include more shares than such holder requested to be registered, the excess shall be allocated among other requesting holders pro rata based on their ownership of Registrable Shares. No other securities requested to be included in a registration for the account of anyone other than the Company or the Stockholders or holders of similar written registration rights shall be included in a registration unless all Registrable Shares requested to be included in such registration are so included.

8.5 Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any of the Registrable Shares under the Securities Act, the Company shall:

(a) file with the Commission a Registration Statement with respect to such Registrable Shares and use its best efforts to cause that Registration Statement to become and remain effective;

(b) as expeditiously as possible prepare and file with the Commission any amendments and supplements to the Registration Statement and the prospectus included in the Registration Statement as may be necessary to keep the Registration Statement effective for a period of not less than ninety (90) days from the effective date;

(c) as expeditiously as possible furnish to each selling Stockholder such reasonable numbers of copies of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as the selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by the selling Stockholder; and

(d) as expeditiously as possible use its best efforts to register or qualify the Registrable Shares covered by the Registration Statement under the securities or Blue Sky laws of such states as the selling Stockholder shall reasonably request, and do any and all other acts and things that may be necessary or desirable to enable the selling Stockholder to consummate the public sale or other disposition in such jurisdictions of the Registrable Shares owned by the selling Stockholder; provided, however, that the Company shall not be required in connection with this paragraph (d) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction.

If the Company has delivered preliminary or final prospectuses to the selling Stockholder

and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify the selling Stockholder and, if requested, the selling Stockholder shall immediately cease making offers of Registrable Shares and shall return all prospectuses to the Company. The Company shall promptly provide the selling Stockholder with revised prospectuses and, following receipt of the revised prospectuses, the selling Stockholder shall be free to resume making offers of the Registrable Shares.

8.6 Allocation of Expenses. The Company shall pay the Registration Expenses for both registrations requested by the Stockholders pursuant to paragraph (a) of subsection 8.3 of this Agreement and of all registrations pursuant to paragraph (b) of subsection 8.3 and pursuant to subsection 8.4 of this Agreement. If a registration requested by the Stockholders pursuant to paragraph (a) of subsection 8.3 is withdrawn at the request of the Stockholders requesting it (other than as a result of information concerning the business or financial condition of the Company which is made known to the Stockholders after the date on which such registration was requested) and if the requesting Stockholders elect not to have such registration counted as a registration requested under paragraph (a) of subsection 8.3, the requesting Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. For purposes of this Section, the term “Registration Expenses” shall mean all expenses incurred by the Company in complying with this Section 8, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, fees and disbursements of counsel for the Company and one counsel for the selling Stockholders, state Blue Sky fees and expenses, and the expense of any special audits incident to or required by any such registration, but excluding underwriting discounts and selling commissions and fees and disbursements of more than one counsel for the selling Stockholders. Such underwriting discounts, selling commissions and counsel fees and disbursements shall be borne pro rata by the selling Stockholders in accordance with the number of their Registrable Shares included in such registration.

8.7 Indemnification.

(a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, to the extent permitted by law the Company will indemnify and hold harmless the seller of such Registrable Shares, each underwriter of such Registrable Shares and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will reimburse such seller, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such seller, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company

will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such seller, underwriter or controlling person specifically for use in the preparation thereof.

(b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, to the extent permitted by law each seller of Registrable Shares severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such seller, specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of such Stockholder hereunder shall be limited to an amount equal to the proceeds to each Stockholder of Registrable Shares sold as contemplated herein. Indemnification of an underwriter pursuant to this subsection 8.7 shall not be interpreted as providing relief of such underwriter from any or all of its due diligence obligations. Further, an underwriter shall not be entitled to indemnification pursuant to this subsection in the event that it fails to deliver to any selling Stockholder any preliminary or final or revised prospectus, as required by the Rules and Regulations of the Commission. Finally, no indemnification shall be provided pursuant to this subsection in the event that any error in a preliminary prospectus of the Company is subsequently corrected in the final prospectus of the Company for a particular offering.

(c) Each party entitled to indemnification under this subsection 8.7 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld); and provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 8. The Indemnified Party may participate in such defense at such party’s expense; provided, however, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential

differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party.

8.8 Indemnification with Respect to Underwritten Offering. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering, the Company agrees to enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of an issuer of the securities being registered and customary covenants and agreements to be performed by such issuer, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering.

8.9 Information by Holder. Each holder of Registrable Shares included in any registration shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 8.

8.10 “Stand-Off” Agreement. Stockholders, if requested by the Company and an underwriter of Common Stock or other securities of the Company, shall agree not to sell or otherwise transfer or dispose of any Registrable Shares of the Company held by such Stockholder for a specified period of time (not to exceed one (1) year) following the effective date of a Registration Statement; provided, that, all stockholders holding more than 1 % of the outstanding Common Stock and all officers and directors of the Company enter into similar agreements. Such agreement shall be in writing in a form satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of the stand-off period.

8.11 Rule 144 Requirements. With a view to making available to the Stockholders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit a Stockholder to sell securities of the Company to the public without registration, upon its registration pursuant to the Securities Act or the Exchange Act, the Company agrees to use its best efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act;

(b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

(c) furnish to any holder of Registrable Shares upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the closing of the first sale of securities by the Company pursuant to a Registration Statement), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such holder may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration.

8.12 Selection of Underwriter. In the case of any registration effected pursuant to subsection 8.3, the requesting Stockholders shall have the right to designate the managing underwriter, subject to the approval of the Company, which approval may not be unreasonably withheld or delayed.

CONTINUATION SHEET 4A

4.1 Undesignated Preferred Stock

Except to the extent otherwise designated herein, the Board of Directors is authorized, subject to limitations prescribed by law and the provisions of this Article Fourth, to provide by resolution for the issuance of the shares of Preferred Stock in one or more series, and by filing a certificate pursuant to the applicable law of the Commonwealth of Massachusetts, to establish from time to time the number of shares to be included in each such series, and to fix the designations, powers, preferences and rights of the shares of each such series and qualifications, limitations or restrictions thereof. The authority of the Board with respect to each series shall include, but shall not be limited to, determination of the following:

(a) The number of shares constituting that series and the distinctive designation of that series;

(b) The dividend rate, if any, on the shares of that series, whether dividends shall be cumulative, and if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of the series;

(c) Whether that series shall have voting rights, in addition to the voting rights provided by law, and, if so, the terms of such voting rights;

(d) Whether that series shall have conversion privileges, and, if so, the terms and conditions of such conversion, including provision for adjustment of the conversion rate in such events as the Board of Directors shall determine;

(e) Whether or not the shares of that series shall be redeemable, and if so, the terms and conditions of such redemption, including the date or dates upon or after which they shall be redeemable, and the amount per share payable in case of redemption, which amount may vary under different conditions and at different redemption dates;

(f) Whether that series shall have a sinking fund for the redemption or purchase of shares of that series, and if so, the terms and amount of such sinking fund;

(g) The rights of the shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Corporation, and the relative rights of priority, if any, of payment of shares of that series; and

(h) Any other relative rights, preferences and limitation of that series.

If upon any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the assets available for distribution to holders of shares of Preferred Stock of all series shall be insufficient to pay such holders the full preferential amount to which they are entitled, then such assets shall be distributed ratably among the shares of all series of Preferred Stock in accordance with the respective preferential amounts (including unpaid cumulative dividends, if any) payable with respect thereto.

4.2 Series A Convertible Preferred Stock

4.2.1. Designation. A total of 5,000,000 shares of the Preferred Stock shall be designated the “Series A Convertible Preferred Stock.” As used herein the term “Series A Preferred Stock” means the shares of Series A Convertible Preferred Stock. Upon the conversion of any shares of Series A Preferred Stock or upon any other reacquisition of such shares by the Corporation, such shares shall be restored to the status of undesignated Preferred Stock, which shall be subject to issuance in accordance with Section 4.1. Upon any such conversion or reacquisition, the Board of Directors of the Corporation may, without action by the stockholders, authorize the restatement of these Articles of Organization either to reduce the number of shares of Preferred Stock designated as Series A Preferred Stock to reflect a partial conversion or reacquisition, or to eliminate this Section 4.2 to reflect the conversion or reacquisition of all outstanding shares of Series A Preferred Stock.

4.2.2. Dividends. The holders of the Series A Preferred Stock shall be entitled to receive, when and as declared by the Board of Directors of the Corporation and upon the liquidation, dissolution or winding up of the Corporation, out of any funds legally available therefor, dividends at the annual rate of $ 0.01 per share (such dividend subject to equitable adjustment in the event of any stock dividend, stock split, combination, reorganization, recapitalization, reclassification or other similar event), payable in preference and priority to any payment of any cash dividend on the Common Stock. Such dividends shall accrue and be deemed to accrue semi-annually on each March 1 and September 1 whether or not earned or declared, and shall be cumulative so that if at any time such dividends on the Series A Preferred Stock shall not have been paid, or declared and set apart for payment, the deficiency shall be fully paid or declared and set apart for payment before any dividend shall be paid on or declared or set apart for the Common Stock. Unless all accrued dividends on the Series A Preferred Stock pursuant to this Section shall have been paid or declared and a sum sufficient for the payment thereof set apart, (i) no dividend shall be paid or declared, and no distribution shall be made, on any Common Stock, and (ii) no shares of Common Stock shall be purchased, redeemed or acquired by the Corporation and no amounts shall be paid into or set aside or made available for the purchase, redemption or acquisition thereof; provided, however, that this restriction shall not apply to the repurchase of shares of Common Stock held by employees, consultants, directors or officers of the Corporation which are subject to stock repurchase agreements under which the Corporation has the right to repurchase such shares at the original purchase price per share in the event of termination of employment.

4.2.3. Liquidation, Dissolution or Winding Up.

(a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders, but before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, an amount equal to $0.14 per share (subject to equitable adjustment in the event of any stock dividend, stock split, combination, reorganization, recapitalization, reclassification or other similar event affecting such shares) plus all accrued but unpaid dividends. If upon any such liquidation dissolution or winding up of the Corporation the remaining assets of the Corporation available for distribution to its stockholders shall be

insufficient to pay the holders of shares of Series A Preferred Stock the full amount to which they shall be entitled, the holders of shares of Series A Preferred Stock shall share ratably in any distribution of the remaining assets and funds of the Corporation in proportion to the respective amounts of Series A Preferred Stock held by them.

(b) After the payment of all preferential amounts required to be paid to the holders of Series A Preferred Stock upon the dissolution, liquidation or winding up of the Corporation, the holders of shares of Common Stock then outstanding shall be entitled to receive the remaining assets and funds of the Corporation available for distribution to its stockholders.

(c) The merger or consolidation of the Corporation into or with another corporation, or the sale of all or substantially all the assets of the Corporation, shall be deemed to be a liquidation, dissolution or winding up of the Corporation for purposes of this Section 4.2.3; provided, however, that each holder of Series A Preferred Stock shall have the right to elect the benefits of the provisions of Section 4.2.5.(f) hereof in lieu of receiving payment in liquidation, dissolution or winding up of the Corporation pursuant to this Section 4.2.3.

4.2.4. Voting.

(a) Except as otherwise expressly provided in this Section 4.2.4. or in Section 4.2.7. hereof, or as required by law, each holder of outstanding shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of whole shares of Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible (as adjusted from time to time pursuant to Section 4.2.5. hereof), at each meeting of stockholders of the Corporation (and written actions of stockholders in lieu of meetings) with respect to any and all matters presented to the stockholders of the Corporation for their action or consideration. All voting for election of directors shall be non-cumulative. Except as otherwise expressly provided herein or as required by law, holders of Series A Preferred Stock shall vote together with the holders of Common Stock as a single class.

(b) So long as shares of Series A Preferred Stock are issued and outstanding, there shall be six (6) directors of the Corporation: four (4) “Class A” directors and two (2) “Class B” directors. The Class A directors shall be nominated by any holder of Common Stock or Preferred Stock and elected by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock and Preferred Stock, voting together as a single class, on an as-converted basis. The Class B directors shall be nominated by any holder of Series A Preferred Stock and elected by the affirmative vote of the holders of a majority of the outstanding shares of Series A Preferred Stock, voting separately as a class. Each director shall be elected at the annual meeting of stockholders and shall serve until his successor is elected and qualified or until his earlier resignation or removal. Any director who shall have been elected by the holders of Common Stock or Series A Preferred Stock, as the case may be, may be removed during his term of office, either for or without cause, by and only by, the affirmative vote of the holders of a majority of the shares of the Common Stock or Series A Preferred Stock, as the case may be, who elected such director, given in writing or at a special meeting of such stockholders duly called for that purpose. Any vacancy in the office of a Class A director may be filled by the remaining Class A directors or the holders of a majority of the outstanding shares of the Common Stock and Preferred Stock, voting together as a single class, on an as-converted basis. Any vacancy in the office of a Class B director may be filled by the remaining Class B director or by the holders of a majority of the outstanding shares of Series A Preferred Stock.

4.2.5 Optional Conversion. The holders of the Series A Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

(a) Right to Convert. Each issued and outstanding share of Series A Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing $0.14 by the Conversion Price (as defined below) in effect at the time of conversion. The conversion price per share at which shares of Common Stock shall be deliverable upon conversion of Series A Preferred Stock without the payment of additional consideration by the holder thereof (the “Conversion Price”) shall initially be $0.14 and the rate at which shares of Series A Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below.

In the event of a liquidation of the Corporation (including any transaction treated as a liquidation under Section 4.2.3.(c) hereof), the Conversion Rights shall terminate at the close of business on the business day preceding the date fixed for the payment of any amounts distributable on liquidation to the holders of Series A Preferred Stock.

(b) Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to the product of such fraction multiplied by the market price of one share of the Corporation’s Common Stock on the Conversion Date, as such term is defined in subsection 4.2.5.(c)(i) below.

(i) In order for a holder of Series A Preferred Stock to convert shares of Series A Preferred Stock into shares of Common Stock, such holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock, at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent), together with written notice that such holder elects to convert all or any number of the shares of the Series A Preferred Stock represented by such certificate or certificates. Such notice shall state such holder’s name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued and the number of shares of Series A Preferred Stock to be converted. If required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or his or its attorney duly authorized in writing. The date of receipt of such certificates and notice by the transfer agent or by the Corporation if the Corporation serves as its own transfer agent) shall be the conversion date (“Conversion Date”) and the conversion shall be deemed effective as of the close of business on the Conversion Date. The Corporation shall, as soon as practicable after the Conversion Date, issue and deliver at such office to such holder of Series A Preferred Stock, or to his or its nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled, together with cash in lieu of any fraction of a share.

(ii) The Corporation shall at all times when the Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of the Series A Preferred Stock, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Common Stock at such adjusted Conversion price.

(iii) Upon any such conversion, no adjustment to the Conversion Price shall be made for any accrued (whether or not declared) and unpaid dividends on the Series A Preferred Stock surrendered for conversion or on the Common Stock delivered upon conversion.

(iv) All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares, including the rights, if any, to receive notices or dividends and to vote, shall immediately cease and terminate at the close of business on the Conversion Date, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be reissued, and the Corporation may from time to time take such appropriate action as may be necessary to reduce the authorized Series A Preferred Stock accordingly.

(d) Adjustments to Conversion Price for Diluting Issues.

(i) Special Definitions. For purposes of this Subsection 4.2.5.(d), the following definitions shall apply:

(A) “Option” shall mean any outstanding rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities, excluding rights, warrants and options granted on or after the Original Issue Date to employees, officers, directors or consultants of the Corporation or any subsidiary thereof pursuant to an option plan, stock purchase plan or other plan or agreement adopted or approved by the Board of Directors (including the Class B directors).

(B) “Original Issue Date” shall mean the date on which any shares of Series A Preferred Stock were first issued.

(C) “Convertible Securities” shall mean any evidences of indebtedness, shares (other than Common Stock and Series A Preferred Stock) or other securities directly or indirectly convertible into or exchangeable for Common Stock.

(D) “Additional Shares of Common Stock” shall mean all shares of Common Stock issued (or, pursuant to Subsection 4.2 .5.(d)(iii) below, deemed to be issued) by

the Corporation after the Original Issue Date, other than shares of Common Stock issued or issuable:

(I)

upon conversion of shares of Series A Preferred Stock or other Convertible Securities issued prior to the Original Issue Date;

(II)

as a dividend or distribution on Series A Preferred Stock;

(III)

by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock; or

(IV)

upon the exercise of options excluded from the definition of “Option” in Subsection 4.2.5.(d)(i)(A).

(E) “Common Stock Deemed Outstanding” means, at any given time, the number of shares of Common Stock actually outstanding at such time, plus the number of shares of Common Stock issuable at such time upon conversion of the Series A Preferred Stock or other Convertible Securities then outstanding, plus the number of shares of Common Stock issuable at any time upon the exercise of all then outstanding options, warrants or other rights to purchase Common Stock (whether or not excluded from the definition of the term “Option” in Section 4.2.5.(d)(i)(A).

(ii) No Adjustment of Conversion Prices. No adjustment in the number of shares of Common Stock into which the Series A Preferred Stock is convertible shall be made, by adjustment in the applicable Conversion Price thereof or otherwise, if prior to such adjustment the Corporation receives written notice from the holders of at least 67% of the outstanding shares of Series A Preferred Stock agreeing that no such adjustment shall be made. The Corporation shall provide written notice of any such agreement to all registered holders of Series A Preferred Stock. In addition, no adjustment shall be made in the Conversion Price as the result of the issuance of Additional Shares of Common Stock or otherwise, unless the consideration per share (determined pursuant to Subsection 4.2.5.(d)(v)) for an Additional Share of Common Stock issued or deemed to be issued by the Corporation is less than the Conversion Price in effect on the date of, and immediately prior to, the issue of such Additional Shares of Common Stock.

(iii) Issue of Options and Convertible Securities Deemed Issue of Additional Shares of Common Stock. If the Corporation at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date, provided that Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration per share (determined pursuant to Subsection 4.2.5.(d)(v) hereof) of such Additional Shares of Common

Stock would be less than the Conversion Price in effect on the date of and immediately prior to such issue, or such record date, as the case may be, and provided further that in any such case in which Additional Shares of Common Stock are deemed to be issued:

(A) no further adjustment in the Conversion Price shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities;

(B) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase in the consideration payable to the Corporation, or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

(C) no recomputation pursuant to clause (B) above shall have the effect of increasing the Conversion Price to an amount which exceeds the lower of (i) the applicable Conversion Price on the original adjustment date, or (ii) the Conversion Price that would have resulted from any issuance of Additional Shares of Common Stock between the original adjustment date and such recomputation date; and

(D) upon the expiration or termination of any unexercised Option, the Conversion Price shall be readjusted, and the Additional Shares of Common Stock deemed issued as the result of the original issue of such Option shall not be deemed issued for the purpose of such readjustment.

(iv) Adjustment of Conversion Price upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 4.2.5.(d)(iii)), without consideration or for a consideration per share less than the Conversion Price in effect on the date of and immediately prior to such issue, then forthwith upon such issue the Conversion Price will be reduced to a Conversion Price determined in accordance with the following formula:


New Conversion Price =		P1Q1 + P2Q2
		Q1+ Q2

where:


PI	=	Conversion Price in effect immediately prior to such issue;

Q1	=	Number of shares of Common Stock Deemed Outstanding (as defined in Subsection 4.2.5.(d)(i)(E)) immediately prior to such issue;

P2	=	Average price per share received by the Corporation upon such issue; and

Q2	=	Number of shares of Common Stock issued, or deemed to have been issued, in the subject transaction;

provided that in computing each new Conversion Price the result shall be rounded to the nearest hundredth of a cent.

(v) Determination of Consideration. For purposes of this Subsection 4.2.5.(d), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

(A) Cash and property: Such consideration shall:

(I) insofar as it consists of cash, be computed at the aggregate of cash received by the Corporation, excluding amounts paid or payable for accrued interest or accrued dividends;

(II) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and

(III) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith by the Board of Directors.

(B) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Subsection 4.2.5.(d)(iii), relating to Options and Convertible Securities, shall be determined by dividing

(x) the total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such options or the conversion or exchange of such Convertible Securities.

(vi) Adjustment for Stock Splits, Stock Dividends, Subdivisions, Combinations or Consolidation of Common Stock. In the event the outstanding shares of Common Stock shall be split, subdivided, combined or consolidated, by reclassification or otherwise, into a greater or lesser number of shares of Common Stock, and in the event that the

Corporation shall issue shares of Common Stock by way of a stock dividend or other distribution to the holders of Common Stock, the Conversion Price in effect immediately prior to such split, subdivision, stock dividend, combination or consolidation shall, concurrently with the effectiveness of such split, subdivision, stock dividend, combination or consolidation, be increased or decreased proportionately.

(e) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 4.2.5., the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series A Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished to such holder a similar certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price then in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which then would be received upon the conversion of Series A Preferred Stock.

(f) Merger or Sale of Assets. If at any time or from time to time there shall be a merger or consolidation of the Corporation with or into another corporation, or the sale of all or substantially all of the Corporation’s properties and assets to any other person, then, as a part of such merger, consolidation or sale, provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of the Series A Preferred Stock, the number of shares of stock or other securities or property of the Corporation, or of the successor corporation resulting from such merger, consolidation or sale, to which a holder of Common Stock issuable upon conversion would have been entitled on such merger, consolidation, or sale. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4.2.5 with respect to the rights of the holders of the Series A Preferred Stock after the merger, consolidation or sale to the end that the provisions of this Section 4.2.5. (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock) shall be applicable after that event in as nearly equivalent a manner as may be practicable.

(g) Notice of Record Date. In the event:

(i) that the Corporation declares a dividend (or any other distribution) on its Common Stock payable in Common Stock or other securities of the Corporation;

(ii) that the Corporation subdivides or combines its outstanding shares of Common Stock;

(iii) of any reclassification of the Common Stock of the Corporation (other than a subdivision or combination of its outstanding shares of Common Stock or a stock dividend or stock distribution thereon), or of any consolidation or merger of the Corporation into or with another corporation, or of the sale of all or substantially all of the assets of the Corporation; or

(iv) of the involuntary or voluntary dissolution, liquidation or winding up of

the Corporation; then the Corporation shall cause to be filed at its principal office or at the office of the transfer agent of the Series A Preferred Stock, and shall cause to be mailed to the holders of the Series A Preferred Stock at their last addresses as shown on the records of the Corporation or such transfer agent, at least ten days prior to the record date specified in (A) below or twenty days before the date specified in (B) below, a notice stating:

(A) the record date of such dividend, distribution, subdivision or combination, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, subdivision or combination are to be determined, or

(B) the date on which such reclassification, consolidation, merger, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, dissolution or winding up.

4.2.6. Automatic Conversion.

(a) All outstanding shares of Series A Preferred Stock shall be deemed automatically converted into shares of Common Stock at the then effective applicable Conversion Price upon the effective date of a registration statement covering the public offering by the Corporation of its Common Stock under the Securities Act of 1933, as amended (“Securities Act”) on a fully underwritten, firm commitment basis, where the aggregate net proceeds to the Corporation (after deduction of underwriting discounts and commissions) is not less than $15,000,000 and the per share sales price of such securities equals or exceeds $7.00 (such amount to be equitably adjusted upon the occurrence of any stock split, stock dividend, combination, reclassification or other similar event) (an “Automatic Conversion Event”). On or after the date of occurrence of an Automatic Conversion Event, and in any event within 10 days after receipt of notice, by mail, postage prepaid from the Corporation of the occurrence of such event, each holder of record of shares of Series A Preferred Stock shall surrender such holder’s certificates evidencing such shares at the principal office of the Corporation or at such other place as the Corporation shall designate, and shall thereupon be entitled to receive certificates evidencing the number of shares of Common Stock into which such shares of Series A Preferred Stock are converted and cash as provided in subsection 4.2.5.(b) in respect of any fraction of a share of Common Stock otherwise issuable upon such conversion. On the date of the occurrence of an Automatic Conversion Event, each holder of record of shares of Series A Preferred Stock shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, notwithstanding that the certificates representing such shares of Series A Preferred Stock shall not have been surrendered at the office of the Corporation, that notice from the Corporation shall not have been received by any holder of record of shares of Series A Preferred Stock, or that the certificates evidencing such shares of Common Stock shall not then be actually delivered to such holder.

(b) All certificates evidencing shares of Series A Preferred Stock which are required to be surrendered for conversion in accordance with the provisions hereof shall, from and after the date such certificates are so required to be surrendered, be deemed to have been retired and cancelled and the shares of Series A Preferred Stock represented thereby converted into Common Stock for all purposes, notwithstanding the failure of the holder or holders thereof to surrender such certificates on or prior to such date.

4.2.7. Restrictions and Limitations.

(a) Except as expressly provided herein or as required by law, so long as any shares of the Series A Preferred Stock remain outstanding, the Corporation shall not, and shall not permit any subsidiary (which shall mean any corporation or trust of which the Corporation directly or indirectly owns at the time a majority of the outstanding shares of such corporation or trust entitled to vote in the election of directors) to, without the approval by vote or written consent by the holders of at least a 67% of the then outstanding shares of the Series A Preferred Stock, each share of Series A Preferred Stock to be entitled to one vote in each instance:

(i) Redeem, purchase or otherwise acquire for value any share or shares of Series A Preferred Stock;

(ii) Authorize or issue, or obligate itself to authorize or issue, any other equity security senior to or on a parity with the Series A Preferred Stock as to dividends or liquidation preferences;

(iii) Increase or decrease (other than by conversion as permitted hereby) the total number of authorized shares of Series A Preferred Stock;

(iv) Effect any sale, lease, assignment, transfer or other conveyance other than in the ordinary course of business, of a substantial portion (i.e., 30% or more) of all or substantially all of the assets or capital stock of the Corporation or any subsidiary thereof, or any consolidation or merger involving the Corporation or any subsidiary thereof, or any reclassification or other change of stock, or any recapitalization or any dissolution, liquidation or winding up of the Corporation;

(v) Make any material change in the nature of its business as carried on at the date hereof or as contemplated in written materials delivered to the purchasers of the Series A Preferred Stock at the time of their acquisition thereof; or

(vi) Sell, assign, license or otherwise dispose of or voluntarily part with control of any of the Corporation’s or any subsidiary’s intellectual property rights to any individual, corporation, partnership, joint venture, trust or unincorporated organization or a government or any agency or political subdivision thereof.

(b) The Corporation shall not amend its Articles of Organization without the approval, by vote or written consent, of the holders of at least 67% of the then outstanding shares of Series A Preferred Stock, each share of Series A Preferred Stock to be entitled to one vote in each instance, if such amendment would adversely affect any of the rights, preferences, privileges of or limitations provided for herein for the benefit of any shares of Series A Preferred Stock. Without limiting the generality of the next preceding sentence, the Corporation will not amend its Articles of Organization without the approval by the holders of at least 67% of the then outstanding shares of Series A Preferred Stock if such amendment would:

(i) Change the relative seniority rights of the holders of Series A Preferred Stock as to the payment of dividends in relation to the holders of any other capital stock of the Corporation;

(ii) Reduce the amount payable to the holders of Series A Preferred Stock upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation, or change the relative seniority of the liquidation preferences of the holders of Series A Preferred Stock to the rights upon liquidation of the holders of any other capital stock of the Corporation or change the dividend rights of the holders of Series A Preferred Stock;

(iii) Change or modify the conversion rights of the holders of Series A Preferred Stock provided for in Sections 4.2.5. and 4.2.6. herein; or

(iv) Change any of the rights, preferences, privileges or limitations provided for herein relating to the election of directors (including any increase or decrease in the number of directors).

4.3 Common Stock

The Common Stock is subject to the rights and preferences of the Preferred Stock as hereinbefore set forth or authorized.

Subject to the provisions of any applicable law or of the bylaws of the Corporation as from time to time amended, with respect to the fixing of a record date for the determination of stockholders entitled to vote, and except as otherwise provided herein or by law or by the resolution or resolutions providing for the issue of any series of Preferred Stock, the holders of outstanding shares of Common Stock shall have exclusive voting rights for the election of directors and for all other purposes, each holder of record of shares of Common Stock being entitled to one vote for each share of Common Stock standing in his name on the books of the Corporation.

Subject to the rights of any one or more series of Preferred Stock, the holders of Common Stock shall be entitled to receive such dividends from time to time as may be declared by the Board of Directors out of any funds of the Corporation legally available for the payment of such dividends.

In the event of the liquidation, dissolution, or winding up of the Corporation, whether voluntary or involuntary, after payment shall have been made to the holders of the Preferred Stock the full amount to which they are entitled, the holders of Common Stock shall be entitled to share ratably according to the number of shares of Common Stock held by them, in all remaining assets of the Corporation available for distribution to its stockholders.

4.4 Issuance

Subject to the provisions of this Articles of Organization and except as otherwise provided by law, the shares of stock of the Corporation, regardless of class, may be issued for such consideration and for such corporate purposes as the Board of Directors may from time to time determine.

CONTINUATION SHEET 6A

6.1 Meetings of the stockholders may be held anywhere within the United States.

6.2 No contract or other transaction of this corporation with any other person, corporation, association, or partnership shall be affected or invalidated by the fact that (i) this corporation is a stockholder or partner in such other corporation, association, or partnership, or (ii) any one or more of the officers or directors of this corporation is an officer, director or partner of such other corporation, association or partnership, or (iii) any officer or director of this corporation, individually or jointly with others, is a party to or is interested in such contract or transaction. Any director of this corporation may be counted in determining the existence of a quorum at any meeting of the board of directors for the purpose of authorizing or ratifying any such contract or transaction, and may vote thereon, with like force and effect as if he were not so interested or were not an officer, director, or partner of such other corporation, association, or partnership.

6.3 The corporation may be a partner in any business enterprise which it would have power to conduct itself.

6.4 The By-laws may provide that the directors may make, amend, or repeal the By-laws in whole or in part, except with respect to any provision thereof which by law, these articles of organization, or the By-laws requires action by the stockholders.

6.5 A director shall not be liable to the corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, except to the extent that the elimination or limitation of liability is not permitted under the Massachusetts Business Corporation Law as in effect when such liability is determined. No amendment or repeal of this provision shall deprive a director of the benefits hereof with respect to any act or omission occurring prior to such amendment or repeal.

6.6 Classified Board. At such time as there are no shares of Series A Preferred Stock issued and outstanding, the Board of Directors shall consist of not less than three nor more than fifteen directors, the exact number to be determined from time to time by resolution adopted by the affirmative vote of a majority of the directors then in office. At such time, the directors shall be divided into three classes, as nearly equal in number as the then total number of directors constituting the entire Board permits, with the term of office of one class expiring each year. The initial directors of the first class shall be elected to hold office for a term expiring at the next succeeding annual meeting, the initial directors of the second class shall be elected to hold office for a term expiring at the second succeeding annual meeting and the initial directors of the third class shall be elected to hold office for a term expiring at the third succeeding annual meeting. At each succeeding annual meeting of stockholders beginning in the first year following the election of such staggered Board of Directors, successors to the class of directors whose term expires at that meeting shall be elected for a three year term. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional directors of any class elected to fill a vacancy resulting from an increase in the size of such class shall hold office for a term that shall coincide with the remaining term of that class, but in no event will a decrease in the number of directors shorten the term of any incumbent director. Any vacancies

in the Board of Directors for any reason, and any directorships resulting from any increase in the number directors, may be filled by the Board of Directors, acting by a majority of the directors then in office, although less than a quorum, and any directors so chosen shall hold office until the next election of the class for which such directors shall have been chosen. Notwithstanding the foregoing, and except as otherwise required by law, whenever the holders of any one or more series of Preferred Stock shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the election, terms of office and other features of such directorships shall be governed by the terms of these Articles of Organization and certificates of designation applicable thereto, and such directors so elected shall not be divided into classes pursuant to this Section 6.6 unless expressly provided by such terms. Subject to the foregoing, at each annual meeting of stockholders the successors to the class of directors whose terms shall then expire shall be elected to hold office for a term expiring at the annual meeting of the year in which their term expires and until their successors shall be elected and qualified, subject to prior death, resignation, retirement or removal.

Exhibit B

CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT

In consideration of my employment by Genzyme Transgenics Corporation, a Massachusetts corporation (the “Company”), I hereby agree as follows:

1. I will make full and prompt disclosure to the Company of all inventions, improvements, modifications, discoveries, methods, biological materials and developments (all of which are collectively termed “developments” hereinafter), whether patentable or not, made or conceived by me or under my direction during my employment, whether or not made or conceived during normal working hours or on the premises of the Company. I do not have any developments other than those I have already disclosed to you.

2. I agree that all developments covered by Paragraph 1 shall be the sole property of the Company and its assigns, and the Company and its assigns shall be the sole owner of all patents and other rights in connection therewith. I hereby assign to the Company any rights I may have or acquire in all developments. I further agree as to all developments to assist the Company in every proper way (but at the Company’s expense) to obtain and from time to time enforce patents on developments in any and all countries, and to that end I will execute all documents for use in applying for and obtaining such patents thereon and enforcing same, as the Company may desire, together with any assignments thereof to the Company or persons designated by it, and I hereby appoint the Company as my attorney to execute and deliver any such documents or assignments on my behalf in the event I fail or refuse to execute and deliver any such documents or assignments requested by the Company. My obligation to assist the Company in obtaining and enforcing patents for developments in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after such termination for time actually spent by me at the Company’s request on such assistance.

I understand that this Paragraph 2 does not apply to developments (a) for which no equipment, supplies, facilities or trade secret information of the Company were used, (b) which were developed entirely on my own time, (c) which do not relate (i) to the business of the Company or (ii) to the Company’s actual or demonstrably anticipated research or development, and (d) which do not result from any work performed by me for the Company.

3. I hereby represent that, to the best of my knowledge, I have no present obligation to assign to any former employer or any other person, corporation or firm, any developments covered by Paragraph 2. I represent that my performance of all the terms of this Agreement and as an employee of the Company does not and will not breach any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any agreement (either written or oral) in conflict herewith.

4. I will also assign to the Company any and all copyrights and reproduction rights to any material prepared by me in connection with my employment.

5. I understand as part of the consideration for the offer of employment extended to me by the Company and of my employment or continued employment by the Company, that I have not brought and will not bring with me to the Company or use in the performance of my responsibilities at the Company any materials or documents of a former employer which are not generally available to the public, unless I have obtained written authorization from the former employer for their possession and use. Accordingly, this is to advise the Company that the only materials or documents of a former employer which are not generally available to the public that I have brought or will bring to the Company or have used or will use in my employment are identified on Exhibit A, and, as to each such item, I represent that I have obtained prior to the effective date of my employment with the Company written authorization for their possession and use in my employment with the Company.

6. During the course of my employment by the Company, I may learn of the Company’s confidential information or confidential information entrusted to the Company by other persons, corporations, or firms. The Company’s confidential information includes matters not generally known outside the Company, such as developments relating to existing and future products and services marketed or used by the Company and data relating to the general business operations of the Company (e.g., concerning sales, costs, profits, organizations, customer lists, pricing methods, etc.) and any reagents, chemical compounds, cell lines, or subcellular constituents, organisms or other biological materials. I agree not to disclose any confidential information of the Company or of such other persons, corporations, or firms to others or to make use of it, except on the Company’s behalf, whether or not such information is produced by my own efforts. Also, I may learn of developments, ways of business, etc., which in themselves are generally known but whose use by the Company is not generally known, and I agree not to disclose to others such use, whether or not such use is due to my own efforts.

7. At the time I begin my employment and during the term of my employment by the Company, I will not become employed by or act on behalf of any other person, corporation, or firm which is engaged in any business or activity similar to or competitive with that of the Company, unless such employment has been approved by the Company in writing and signed by an appropriate personnel manager of the Company.

8. In the event that my employment is transferred by the Company to a subsidiary or affiliated company (as the case may be), my employment by such company will, for the purposes of this Agreement, be considered as continued employment by the Company, unless I execute an agreement, substantially similar in substance to this Agreement, and until the effective date of said agreement in any such company for which I become employed.

9. Upon termination of my employment, unless my employment is transferred to a subsidiary or affiliated company of the Company, I agree to leave with the Company all records, drawings, notebooks, and other documents pertaining to the Company’s confidential information, whether prepared by me or others, and also any equipment, tools or other devices owned by the Company, then in my possession however such items are obtained, and I agree not to reproduce any document or data relating thereto.

10. My obligations under this Agreement shall survive the termination of my employment regardless of the manner of such termination, and shall be binding upon my heirs, executors, and administrators.

11. Prior to entering the employ of the Company I have terminated employment with all past employers.

12. As a matter of record I have identified on Exhibit B all developments relevant to the subject matter of my employment by the Company which have been made or conceived or first reduced to practice by me alone or jointly with others prior to my engagement by the Company which I desire to remove from the operation of this Agreement; and I covenant that such list is complete. If there is no such list on Exhibit B, I represent that I have made no such developments at the time of signing this Agreement.

13. I agree that in addition to any other rights and remedies available to the Company for any breach by me of my obligations hereunder, the Company shall be entitled to enforcement of my obligations hereunder by court injunction.

14. If any provisions of this Agreement shall be declared invalid, illegal or unenforceable, then such provision shall be enforceable to the extent that a court shall deem it reasonable to enforce such provision. If such provision shall be unreasonable to enforce to any extent, such provision shall be severed and all remaining provisions shall continue in full force and effect.

15. This Agreement shall be effective as of the date set forth below next to my signature.

16. This Agreement shall be governed in all respects by the laws of the Commonwealth of Massachusetts.

IN WITNESS WHEREOF, I have executed this Agreement under seal as of the date below.

I recognize that Genzyme Transgenics Corporation, a Massachusetts corporation (the “Company,” which term shall include its subsidiaries and affiliated entities) desires to retain me in its employ and that the Company wishes to ensure that I do not compete with the Company, as specified below, in the event my employment with the Company is terminated.

In consideration of the Company’s employment or continued employment of me, I agree as follows:

1. I will not, for a period of two (2) years commencing with the termination of my employment with the Company, engage (directly or indirectly) in any activities or render any services similar or reasonably related to those in which I shall have engaged or those which I shall have rendered as an employee of the Company during any part of the two-year period preceding my termination for any trade or business which directly competes with the Company in any place where the Company does or may do business in any line of business engaged in (or planned to be engaged in) by the Company, whether now existing or hereafter established, nor shall I engage in such activities nor render such services for any other person or entity engaged or about to become engaged in such activities to, for or on behalf of any such trade or business.

2. I agree that for a period of one (1) year following the termination of my employment with the Company, I will not solicit or in any manner encourage employees of the Company to leave their employ. I further agree that during such period I will not offer or cause to be offered employment to any person who was employed by the Company at any time during the six (6) months prior to the termination of my employment with the Company.

3. I understand that nothing in this Agreement shall affect my obligations under the “Confidential and Proprietary Information Agreement” between the Company and myself of even date herewith.

If any provision of this Agreement shall be declared invalid, illegal or unenforceable, then such provision shall be enforceable to the extent that a court shall deem it reasonable to enforce such provision. If such provision shall be unreasonable to enforce to any extent, such provision shall be severed from this Agreement and all remaining provisions shall continue in full force and effect.

This Agreement shall be governed in all respects by the laws of the Commonwealth of Massachusetts.
