ARTICLE I

Definitions

1.1 Definitions. Capitalized terms used but not defined in the text of this Agreement shall have the meanings ascribed to them on Exhibit A attached hereto and incorporated herein by reference.

ARTICLE II

Sales by Shareholders

2.1 Restrictions on Transfers.

(a) General. No Shareholder shall sell, offer, assign, pledge, encumber, dispose, or otherwise transfer (collectively, “Transfer”) any interest in any Shares (whether with

or without consideration and whether voluntarily or involuntarily or by operation of law), except pursuant to (i) any sale of Shares to the public pursuant to an underwritten offering registered under the Securities Act of 1933, as amended (the “Securities Act”), or through a broker, dealer or market maker pursuant to the provisions of Rule 144 adopted under the Securities Act or (ii) the provisions of ARTICLES II and III. In addition, any transferee of Shares must execute an agreement to join as a party to this Agreement.

(b) Selling Shareholder Notice. If any Shareholder proposes to Transfer any interest in any Shares (a “Selling Shareholder”) in one transaction or a series of related transactions, then such Selling Shareholder shall promptly give written notice (the “Notice”) to the Company, each of the Shareholders not selling or otherwise transferring Shares (the “Non-selling Shareholders”), and to PharmaBio at least thirty (30) days prior to the closing of such proposed Transfer. The Notice shall describe in reasonable detail the proposed Transfer including, without limitation, the number of Shares to be Transferred, the nature of such proposed Transfer, the aggregate consideration to be paid for the Shares, and the name and address of each prospective transferee. If the Transfer is being made pursuant to the provisions of ARTICLE III hereof, the Notice shall state under which section and subsection the Transfer is being made.

2.2 Right of First Refusal.

(a) With respect to proposed Transfers of Shares, each Non-selling Shareholder shall have the right, exercisable upon written notice to the Selling Shareholder within fifteen (15) days after receipt of the Notice, to elect to purchase the Shares covered in the Notice directly from the Selling Shareholder, on the same terms and conditions specified in the Notice. To the extent that one or more of the Non-selling Shareholders exercise such right in accordance with the terms and conditions set forth below, the number of Shares that the Selling Shareholder may Transfer in the transaction contemplated in the Notice shall be correspondingly reduced.

(b) Each Non-selling Shareholder may purchase from the Selling Shareholder all or any part of that number of Shares equal to the product obtained by multiplying (i) the aggregate number of Shares covered by the Notice by (ii) a fraction, the numerator of which is the number of Shares owned by the Non-selling Shareholder as of the date of the Notice and the denominator of which is the total number of Shares owned by all Non-selling Shareholders as of the date of the Notice.

(c) If any Non-selling Shareholder fails to elect to fully purchase its pro rata share of the Shares pursuant to this Section 2.2, then the Selling Shareholder shall give notice of such failure to the Non-selling Shareholders who did so elect (the ‘Purchasing Participants”), PharmaBio and the Company. Such notice may be made by telephone if confirmed in writing within forty-eight (48) hours. The Purchasing Participants shall have five (5) days from the date such notice was given to agree to acquire their pro rata share of the portion of the Shares not elected to be purchased by the Non-selling Shareholders pursuant to Section 2.2(a). For purposes of this Section 2.2(c), a Purchasing Participant’s pro rata share shall be equal to the product obtained by multiplying (i) the number of Shares not elected to be purchased by Non-selling Shareholders pursuant to Section 2.2(a) by (ii) a fraction, the numerator of which is the number

of Shares held by such Purchasing Participant and the denominator of which is the total number of Shares held by all of the Purchasing Participants.

(d) The Company may, within five (5) days after the Purchasing Participants determine whether to acquire their respective pro rata share, elect to acquire any remaining portion of the Purchasing Participants’ aggregate pro rata share (the “Remaining Shares”) on the terms set forth in the Notice. If the Company does not elect to purchase all of the Remaining Shares, then the Company shall send written notice to PharmaBio stating the number of shares of Remaining Shares available for purchase by PharmaBio. Within fifteen (15) days after receipt of the Company’s notice, PharmaBio shall have the right to elect to acquire all or any part of that number of Remaining Shares.

(e) At the conclusion of the procedure outlined in Section 2.2(d), if all of the Remaining Shares have not been purchased by the Non-selling Shareholders, the Company or PharmaBio, then the Selling Shareholder shall send a second notice (a “Co-Sale Notice”) to all Non-selling Shareholders who did not elect to purchase the Shares notifying them of such failure and of their right of co-sale under Section 2.3 of this Agreement The Co-Sale Notice shall specify the number of Shares not elected to be purchased pursuant to Section 2.2(a) hereof.

2.3 Right of Co-Sale.

(a) In the event that less than all Shares subject to the Notice have been purchased in accordance with Section 2.2 above, each Non-selling Shareholder that does not elect to purchase Shares pursuant to Section 2.2 shall have the right, exercisable upon, written notice to the Selling Shareholder within ten (10)days after the receipt of the Co-Sale Notice described in Section 2.2(e), to Transfer Shares held by such Non-selling Shareholder with the Selling Shareholder to the prospective transferee, on the same terms and conditions specified in the Notice. To the extent that one or more of the Non-selling Shareholders exercises such right in accordance with the terms and conditions set forth below, the number of Shares that the Selling Shareholder may Transfer in the transaction shall be correspondingly reduced.

(b) Each Non-selling Shareholder may Transfer all or any part of that number of Shares held by him equal to the product obtained by multiplying (a) the aggregate number of Shares covered by the Co-Sale Notice by (b) a fraction, the numerator of which is the number of Shares owned by the Non-selling Shareholder at the time of the Transfer and the denominator of which is the total number of Shares owned by all Shareholders at the time of the Transfer.

(c) If any Non-Selling Shareholder fails to elect to fully participate in such sale pursuant to this Section 2.3, the Selling Shareholder shall give notice of such failure to the Shareholders who did so elect (the “Selling Participants”). Such notice may be made by telephone if confirmed in writing within forty-eight (48) hours. The Selling Participants shall have five (5) days from the date such notice was given to agree to Transfer their pro rata share of the remaining Shares available for co-sale. For purposes of this Section 2.3, a Selling Participant’s pro rata share shall be equal to the product obtained by multiplying (a) the number of remaining Shares available for co-sale by (b) a fraction, the numerator of which is the number of Shares held by such Selling Participant and the denominator of which is the total number of Shares held by all of the Selling Participants and the Selling Shareholder.

2.4 Delivery of Co-Sale Shares. Each Selling Participant shall effect its participation in the Transfer by promptly delivering to the Selling Shareholder for Transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent that number of Shares that such Selling Participant elects to Transfer.

2.5 Closing. The stock certificate or certificates, if any, that the Selling Participant delivers to the Selling Shareholder pursuant to Section 2.4 shall be transferred to the prospective transferee in consummation of the Transfer of the Shares pursuant to the terms and conditions specified in the Notice, and the Selling Shareholder shall concurrently therewith remit to such Selling Participant that portion of the Transfer proceeds to which such Selling Participant is entitled by reason of its participation in such Transfer. To the extent that any prospective transferee prohibits such assignment or otherwise refuses to purchase Shares or other securities from a Selling Participant exercising its rights of co-sale hereunder, the Selling Shareholder shall not Transfer to such prospective transferee any Shares unless and until, simultaneously with such Transfer, the Selling Shareholder shall purchase such Shares or other securities from such Selling Participant. To the extent that the Non-selling Shareholders, the Company or PharmaBio as provided in Section 2.2 elect to purchase the Shares covered in the Notice directly from the Selling Shareholder, then such Selling Shareholder shall within ninety (90) days of the date of the Notice (or, if earlier, simultaneous with the consummation of the Transfer of the Shares pursuant to the terms and conditions specified in the Notice) deliver certificate(s) for such Shares to the acquiring Non-selling Shareholder, the Company or PharmaBio as the case may be who shall deliver to the Selling Shareholder the consideration of the type and on the terms set forth in the Notice.

2.6 No Effect on Rights. The exercise or non-exercise of rights by any Party under Sections 22 or 2.3 in one or more Transfers of Shares made by any Selling Shareholder shall not adversely affect such Party’s rights to participate in subsequent Transfers of Shares subject to this ARTICLE II. The failure of any Non-selling Shareholder to exercise its rights pursuant to this ARTICLE II with respect to any proposed Transfer shall not constitute a waiver of such Non-selling Shareholder’s right to exercise its rights under this ARTICLE II with respect to subsequent Transfers.

2.7 Reoffers. Upon compliance in full with the terms and conditions of this ARTICLE II, if there are any Shares remaining to be Transferred, the Selling Shareholder may, no later than seventy-five (75) days following delivery to the Company and each of the Non-selling Shareholders of the Notice, enter into an agreement providing for the closing of the Transfer of the remaining Shares covered by the Notice within thirty (30) days of such agreement on terms and conditions not more favorable to the transferor than those described in the Notice. It shall be a condition to such closing that the transferee shall execute and deliver to the Company an agreement to join as a party to this Agreement. Any proposed Transfer on terms and conditions more favorable than those described in the Notice, as well as any subsequent proposed Transfer of any of the remaining Shares by the Selling Shareholder, shall again be subject to the right of first refusal, co-sale and other rights of the Non-selling Shareholders, the Company and PharmaBio set forth in this ARTICLE II and shall require compliance by the Selling Shareholder with the procedures described in this ARTICLE II.

ARTICLE VII

Purchase Option

7.1 Purchase of Shares. Prior to the date hereof, each Shareholder purchased from the Company, and the Company sold to each Shareholder, Twenty-Five Thousand (25,000) shares of the Company’s Common Stock at a purchase price of $0.10 per share.

7.2 Option.

(a) PharmaBio is hereby granted the right (the “Option”) to purchase at the Appraised Value all or any portion of the Shares of (i) any Shareholder who ceases to be an employee or independent contractor of the Company for any reason (including death or disability) before the first closing of a Qualified Financing or while there exists any Commitment or unpaid principal and interest amounts of Advances under the Loan Agreement, and (ii) any or all Shareholders in the event that the first closing of a Qualified Financing shall not have occurred by December 31, 2006, or an Event of Default shall have occurred.

(b) The Option shall be exercisable by written notice delivered to the applicable Shareholder(s). The notice shall indicate the number of Shares to be purchased and the date on which the purchase is to be effected. The applicable Shareholder(s) shall, prior to the close of business on the date specified for the purchase, deliver to PharmaBio the certificates representing the Shares to be purchased, each certificate to be properly endorsed for transfer. PharmaBio shall, concurrently with the receipt of such stock certificates from the applicable Shareholder(s) as herein provided, pay to each such Shareholder in cash or cash equivalents, an amount equal to the Appraised Value of the Shares being purchased from such Shareholder pursuant to exercise of the Option. For the avoidance of doubt, if PharmaBio exercises the Option with respect to more than one Shareholder pursuant to written notices delivered within five (5) days of one another, then the Appraised Value of the Shares subject to such Option exercises shall be determined in a single appraisal proceeding under Section 7.2(d).

(c) For purposes of this Section 7.2, “Appraised Value” means the price equal to the proceeds that the applicable Shareholder would receive with respect to the Shares being purchased pursuant to exercise of the Option in a transaction in which the Company would be sold as a going concern for its fair market value and in which the Company’s assets would then be liquidated and the net proceeds of such liquidation, after payment of all liabilities, would be distributed to all of the Company’s shareholders in accordance with the Company’s Articles of Incorporation and Bylaws, determined as if all preferred stock were converted to common stock (a“Hypothetical Sale”).

(d) Within fourteen (14) days after the Option is exercised with respect to one or more Shareholders, PharmaBio shall designate by written notice to the applicable Shareholder(s) an appraiser acceptable to PharmaBio, and the applicable Shareholder(s) shall designate by written notice to PharmaBio an appraiser acceptable to the applicable Shareholder(s). If the Option has been exercised with respect to more than one Shareholder, the applicable Shareholders shall have the right to jointly designate an appraiser, provided, however, that if the applicable Shareholders cannot unanimously agree within such fourteen (14)-day period, then the American Arbitration Association office in Charlotte, North Carolina shall appoint an appraiser on behalf of the applicable Shareholders. The two appraisers designated as described above shall select a third appraiser within the ten (10)-day period following the date of designation of the last of them to be designated. If the two appraisers fail to select a third appraiser within such ten (10)-day period, then the third appraiser shall be appointed by the American Arbitration Association office in Charlotte, North Carolina. Each appraiser shall be asked to determine the fair market value of the Company in a Hypothetical Sale, the proceeds that each shareholder would receive in a Hypothetical Sale, and the Appraised Value of the Shares being purchased pursuant to exercise of the Option, and shall use best efforts to make such determinations within thirty (30) days after selection of the final appraiser. The mutual agreement of any two appraisers as to the Appraised Value shall be binding on all parties. If no two appraisers can agree, then the Appraised Value shall be determined by averaging the determinations of the two appraisers whose determinations are closest in amount. All appraisers must be unaffiliated with and independent from the parties to such purchase transaction and experienced (ten years or more) in the appraisal of corporations comparable to the Company.
