of the provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Borrower and the Subsidiaries is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, (i) adversely affect the legality, validity or enforceability of any Transaction Document, (ii) have or result in a material adverse effect on the results of operations, assets, business or condition (financial or otherwise) of the Borrower and the Subsidiaries, taken as a whole, or (iii) adversely impair the Borrower’s ability to perform fully on a timely basis its obligations under any of the Transaction Documents (any of (i), (ii) or (iii), a “Material Adverse Effect”).

(d) No Conflicts.    The execution, delivery and performance of the Transaction Documents by the Borrower and the consummation by the Borrower of the transactions contemplated hereby do not and will not (i) conflict with or violate any provision of the Borrower’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) subject to obtaining the Required Approvals (as defined below), conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation  (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Borrower or Subsidiary debt or otherwise) or other understanding to which the Borrower or any Subsidiary is a party or by which any property or asset of the Borrower or any Subsidiary is bound or affected, or (iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Borrower or a Subsidiary is subject (including federal and state securities laws and regulations) and the rules and regulations of any self-regulatory organization to which the Borrower or its securities are subject, or by which any property or asset of the Borrower or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate, have or result in a Material Adverse Effect.

(u) Transactions With Affiliates and Employees.    Except as set forth in SEC Reports filed at least ten days prior to the date hereof or as described in the Transaction Documents, neither the Borrower nor any Subsidiary was or anticipates being party to any transaction that would be required to be reported and described in accordance with Item 404 of Regulation S-K, which for purposes of this representation and warranty extends to transactions: (i) of which the Borrower has knowledge with employees of the Borrower or a Subsidiary and (ii) with direct and indirect Affiliates of 5% security holders of the Borrower.  The Letter Agreement describes all agreements and understandings creating any obligation related to indebtedness with beneficial owners of 5% or more of the Common Stock and any direct and indirect Affiliates of such Persons.

13

Borrower, together with the proceeds the Borrower would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid. The Borrower does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

(x) Acknowledgment Regarding Loan and Lenders’ Purchase of Securities. The Borrower acknowledges and agrees that each of the Lenders is acting solely in the capacity of an arm’s length lender with respect to this Agreement, the purchase of Securities hereunder, and the transactions contemplated hereby.  The Borrower further acknowledges that no Lender is acting as a financial advisor or fiduciary of the Borrower (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any advice given by any Lender or any of their respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to the Lenders’ purchase of the Securities.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1. Acknowledgment of Dilution.    The Borrower acknowledges that the issuance of the Securities (including the Underlying Shares) will result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Borrower further acknowledges that its obligations under the Transaction Documents, including without limitation its obligation to issue the Securities (including the Underlying Shares) pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim that the Borrower may have against any Lender.

4.2. Furnishing of Information.    As long as any Lender owns the Securities issued or issuable to it, the Borrower covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Borrower after the date hereof pursuant to the Exchange Act. Upon the request of any such Person, the Borrower shall deliver to such Person a written certification of a duly authorized officer as to whether it has complied with the preceding sentence.

4.3. Reservation and Listing of Securities.

(a) The Borrower shall maintain a reserve from its duly authorized shares of Common Stock to comply with its conversion and exercise obligations under the Debentures pursuant to the Transaction Documents.  In connection with the Borrower’s next annual meeting of stockholders, the Board of Directors of the Borrower shall prepare and mail to the stockholders of the Borrower proxy materials requesting authorization to amend the Borrower’s certificate of incorporation to increase the number of shares of Common Stock which the

15

Borrower is authorized to issue so as to provide enough shares to reserve for issuance all of the Underlying Shares issuable upon conversion of the Debentures at an assumed conversion price equal to 50% of the then effective Conversion Price (as defined in the Debentures) and assuming all interest is accreted to principal.  In addition, if on any other date the Borrower would be, if notice of exercise or conversion were to be delivered on such date, precluded from issuing the number of Underlying Shares, as the case may be, issuable upon conversion in full of the Debentures due to the unavailability of a sufficient number of authorized but unissued or reserved shares of Common Stock, then the Board of Directors of the Borrower shall promptly prepare and mail to the stockholders of the Borrower proxy materials requesting authorization to amend the Borrower’s certificate of incorporation to increase the number of shares of Common Stock which the Borrower is authorized to issue so as to provide enough shares for issuance of the Underlying Shares.  In connection with either such stockholder vote, the Board of Directors shall: (a) adopt proper resolutions authorizing such increase, (b) recommend to and otherwise use its best efforts to promptly and duly obtain stockholder approval to carry out such resolutions (and hold a special meeting of the stockholders as soon as practicable, but in any event not later than the 60^th day after delivery of the proxy materials relating to such meeting) and (c) within five business days of obtaining such stockholder authorization, file an appropriate amendment to the Borrower’s certificate of incorporation to evidence such increase.

(b) The Borrower shall: (i) in the time and manner required by the Nasdaq, prepare and file with Nasdaq an additional shares listing application covering the Initial Shares, the SF Shares and the Underlying Shares, (ii) take all steps necessary to cause such shares to be approved for listing on the Nasdaq as soon as possible thereafter, (iii) provide to the Lenders evidence of such listing, and (iv) maintain the listing of such shares on an Eligible Market.

4.4. Conversion and Exercise Procedures.    The form of Holder Conversion Notice included in the Debentures set forth the totality of the procedures required by the Lenders in order to convert the Debentures. No additional legal opinion or other information or instructions shall be necessary to enable the Lenders to convert their Debentures. The Borrower shall honor conversions of the Debentures and shall deliver Underlying Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

4.5. Subsequent Placements.

(a) So long as any Debentures are outstanding, the Borrower will not, directly or indirectly, effect any, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or the Subsidiaries’ equity or equity equivalent securities, including, without limitation, any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable for Common Stock (any such offer, sale, grant, disposition or announcement being referred to as a “Subsequent Placement”) unless the Borrower shall have first complied with this Section 4.5(a).

(i) The Borrower shall not conduct any Subsequent Placement until six months shall have elapsed from the Closing Date.

16

(ii) The Borrower shall deliver to each Lender which at the time of the proposed Subsequent Placement holds a Debenture or Debentures (a “Qualified Lender”) a written notice (the “Offer”) of any proposed or intended issuance or sale or exchange of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the Persons to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to or exchange with each Qualified Lender (A) a pro rata portion of the Offered Securities, based on such Qualified Lender’s pro rata portion of the aggregate purchase price paid by any other Qualified Lenders for all of the Securities purchased hereunder (it being understood that if there shall be only one Qualified Lender, then such Qualified Lender’s pro-rata portion of the Offered Securities shall equal 100%) (the “Basic Amount”), and (B) with respect to each Qualified Lender that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of any other Qualified Lenders as such Qualified Lender shall indicate it will purchase or acquire should any other Qualified Lenders subscribe for less than their Basic Amounts (the “Undersubscription Amount”).   Notwithstanding anything to the contrary set forth in any Transaction Document, in the event that any Offer pertaining to a Subsequent Placement is provided prior to the one year anniversary of the Closing Date, then the price at which a Qualified Lender may participate in such Subsequent Placement shall be the lesser of (a) the price and terms described in the Offer and (b) the Conversion Price then in effect under the Debentures.  In furtherance of the immediately prior sentence, if the Offer is for Common Stock, then the price per share at which a Qualified Lender may acquire such stock shall equal the Conversion Price then in effect, and if for Common Stock Equivalents, then the price at which a Qualified Lender may acquire such Common Stock Equivalents (or the Common Stock issuable in respect thereof) shall be determined by reference to the Conversion Price then in effect.

(iii) To accept an Offer, in whole or in part, a Qualified Lender must deliver a written notice to the Borrower prior to 5:00 p.m., New York time, on the fifth Trading Day after the Offer, setting forth the portion of the Qualified Lender’s Basic Amount that such Qualified Lender elects to purchase and, if such Qualified Lender shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Qualified Lender elects to purchase (in either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Qualified Lenders in the aggregate are less than the total of all of the Basic Amounts, then each Qualified Lender who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), each Qualified Lender who has subscribed for any Undersubscription Amount shall be entitled to purchase that portion of the Available Undersubscription Amount as the Basic Amount of such Qualified Lender bears to the total Basic Amounts of all Qualified Lenders that have

17

subscribed for Undersubscription Amounts, subject to rounding by the Board of Directors to the extent its deems reasonably necessary.

(iv) The Borrower shall have five (5) Trading Days from the expiration of the period set forth in Section 4.5(a)(ii) above to issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Qualified Lenders (the “Refused Securities”), but only to the offerees described in the Offer (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Borrower than those set forth in the Offer.

(v) In the event the Borrower shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 4.5(a)(iii) above), then each Qualified Lender may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Qualified Lender elected to purchase pursuant to Section 4.5(a)(ii) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Borrower actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Qualified Lenders pursuant to Section 4.5 (a)(ii) above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Qualified Lender so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Borrower may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Qualified Lenders in accordance with Section 4.5(a)(i) above.

(vi) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Qualified Lenders shall acquire from the Borrower, and the Borrower shall issue to the Qualified Lenders, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 4.5(a)(iv) above if the Qualified Lenders have so elected, upon the terms and conditions specified in the Offer. The purchase by the Qualified Lenders of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Borrower and the Qualified Lenders of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Qualified Lenders, the Borrower and their respective counsel.

(vii) Any Offered Securities not acquired by the Qualified Lenders or other persons in accordance with Section 4.5(a)(iii) above may not be issued, sold or exchanged until they are again offered to the Qualified Lenders under the procedures specified in this Agreement.

(b) The restrictions contained in paragraph (a) of this Section shall not apply to: (i) the granting of options to employees, officers and directors of the Borrower pursuant to any stock option plan duly adopted by the Borrower or to the issuance of Common Stock upon exercise of such options (except to the extent that any such securities are issued to Xxxxx

00

Xxxxxxxxx), (xx) issuances of Common Stock pursuant to the conversion or exercise (as applicable) of Previous Debentures (pursuant to a request by the holder thereof), options or warrants which are outstanding on the date hereof, as set forth in Schedule 3.1(m) (except to the extent that the resale of such securities would be restricted under the Letter Agreement), (iii) any underwritten public offering of the Common Stock for an aggregate price in excess of $10,000,000 (which shall not include equity lines of credit or similar transactions), (iv) any issuance of shares of Common Stock in satisfaction in full of all accounts payable of the Borrower to a particular vendor incurred in the ordinary course, provided, that that effective per share price utilized in any such issuance shall be greater than the greater of (x) 90% of the then applicable Closing Price and (y) the then effective Conversion Price of the Debenture, and that the Borrower shall not issue shares with an aggregate effective per share price in excess of $3,000,000 under any one or more such issuances or (v) any Subsequent Placement offered at a time when less than $3,000,000 aggregate principal amount of Debentures is outstanding.

4.6. Registration Statements.  Except with respect to a registration statement on Form S-3 with respect to the resale of shares of Common Stock privately placed to vendors as contemplated by Section 4.5(b)(iv), until 181 days following the Closing Date, the Borrower will not file any registration statement (other than on a Form S-8).

4.7. Securities Laws Disclosure; Publicity.  The Borrower shall: (i) on the Closing Date: (x) issue a press release acceptable to the Lenders which includes a description of any and all material and information delivered to the Lenders (or to any agent thereof) which the Borrower believes might constitute material non-public information, and (y) file a Current Report on Form 8-K disclosing the transactions contemplated hereby and (ii) make such other filings and notices in the manner and time required by the Commission.  Except as set forth above, the Borrower shall not publicly disclose the name of any Lender, or include the name of any Lender in any filing with the Commission or any regulatory agency or the Nasdaq (other than the filing of the Transaction Documents with the Commission pursuant to the Exchange Act), without the prior written consent of such Lender, except to the extent such disclosure is required by law or Nasdaq regulations, in which case the Borrower shall provide the Lenders with prior notice of such disclosure.

4.8. Non-Public Information.  The Borrower covenants and agrees that neither it nor any other Person acting on its behalf will provide any Lender or its agents or counsel with any information that constitutes material non-public information, unless prior thereto such Lender shall have executed a written agreement regarding the confidentiality and use of such information.  The Borrower understands and confirms that each Lender shall be relying on the foregoing representations in effecting transactions in securities of the Borrower.

4.9. Use of Proceeds.    The Borrower shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and not for the satisfaction of any portion of the Borrower’s debt (other than payment of trade payables and accrued expenses in the ordinary course of the Borrower’s business and prior practices), to redeem any Borrower equity or equity-equivalent securities or to settle any outstanding litigation, provided, that: (A) the Borrower shall be entitled to use the proceeds from the sale of Securities to settle outstanding litigation (other than with direct or indirect Affiliates or related parties) in an aggregate amount not to exceed $150,000 per calendar year, (B) the Borrower shall use $208,000 of the net proceeds from the

19

sale of the Debentures hereunder for prepaying the 4% premium for prepayment of $5,200,000 of the outstanding principal amount of the secured convertible debentures, in the original principal amount of $10,000,000 (the “August Debentures”), issued and sold to certain holders pursuant to that certain Securities Purchase Agreement dated as of August 12, 2002, among the Borrower and the purchasers signatory thereto (the “August Agreement”), (C) the Borrower shall be entitled to use up to $300,000 from the proceeds from the sale of Securities to pay BioTec in respect of materials and services delivered to the Borrower pursuant to the BioTec License Agreement and (D) to pay up to $4,000,000 of its payables, as set forth in Schedule 4.9 hereof.  The use of proceeds from this financing shall also be governed by the terms of the Letter Agreement and the Subordination Agreements, each of which specifically prohibit certain payments by the Borrower.

4.10. Indemnification.

(a) The Borrower will indemnify and hold harmless each Lender and any of their respective Affiliates or any officer, director, partner, controlling person, employee or agent of a Lender or any of their respective Affiliates (for purposes of this Section, each Lender and such other Persons are referred to as the “Lender Indemnified Parties”) for its respective reasonable legal and other expenses (including the costs of any investigation, preparation and travel) and for any Losses incurred in connection with any Proceeding, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or the Supplement, or any amendment or supplement thereto, and all other documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A, or pursuant to Rule 434, under the Securities Act, or arise out of or are based upon the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading, as such expenses or Losses are incurred. In addition, the Borrower shall indemnify and hold harmless each Lender Indemnified Party from and against any and all Losses, as incurred, arising out of or relating to any breach by the Borrower of any of the representations, warranties or covenants made by the Borrower in this Agreement or any other Transaction Document, or any allegation by a third party that, if true, would constitute such a breach. The conduct of any Proceeding for which indemnification is available under this paragraph shall be governed by Section 4.8(b). The indemnification obligations of the Borrower under this paragraph shall be in addition to any liability that the Borrower may otherwise have and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of each Purchase Indemnified Party. The Borrower also agrees that no Lender Indemnified Party shall have any liability to the Borrower or any Person asserting claims on behalf of or in right of the Borrower in connection with or as a result of the transactions contemplated by the Transaction Documents, except to the extent that any losses, claims, damages, liabilities or expenses incurred by the Borrower result from the gross negligence or willful misconduct of the applicable Lender Indemnified Party in connection with such transactions. If the Borrower breaches its obligations under any Transaction Document, then, in addition to any other liabilities the Borrower may have under any Transaction Document or applicable law, the Borrower shall pay or reimburse each Lender Indemnified Party on demand for all costs of collection and enforcement (including reasonable attorneys fees and expenses). Without limiting the generality of the foregoing, the Borrower

20

specifically agrees to reimburse each Lender Indemnified Party on demand for all costs of enforcing the indemnification obligations in this Agreement.

(b) If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except  (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

(c) An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

(d) All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

4.11. Shareholders Rights Plan.    No claim will be made or enforced by the Borrower or any other Person that any Lender is an “Acquiring Person” under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Borrower, or that any Lender

21

could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Underlying Shares under the Transaction Documents or under any other agreement between the Borrower and the Lenders.

4.12. Post-closing Borrower Revenues.  The Borrower shall have the option to distribute all gross proceeds and revenues it receives from time to time following the Closing Date in excess of an aggregate of $2,650,000 (the “Excess Amount”) in accordance with Section 4.12(a), (b) and (c).  The proceeds and revenues from the following sources shall be subject to this requirement: (i) sale of securities, (ii) post-Closing equipment sales to unrelated third parties, (iii) operating revenues, (iv) any cash which becomes available for use by the Borrower due to a reduction in that certain letter of credit in favor of Xxxx Waffel Machinen in the original principal amount of $3,500,000, provided, that the Borrower’s election to distribute any Excess Amount must be made within 45 days of the close of the applicable calendar quarter with respect to revenues or proceeds received or earned from such quarter pursuant to clauses (i)-(iv) hereof.  Promptly following its receipt of any such revenues, the Borrower will promptly: (x) file a Current Report on Form 8-K with the Commission disclosing such revenues and (y) provide a written notice the Lenders (a “Proceeds Notice”).  Any Excess Amount shall be distributable by the Borrower in the following manner:

(a) 1/3 of an Excess Amount may be used for Borrower working capital purposes.

(b) at the election of each Lender, 1/3 of an Excess Amount multiplied by such Lender’s Purchase Percentage shall be allocated for a prepayment of principal and interest of the Debentures held by such Lender, pursuant to Section 8 of the Debentures.

(c) 1/3 of an Excess Amount shall be allocated either for the repayment of Related Party Loans (as defined under the Letter Agreement) or for the payment to BioTec of amounts due under the BioTec License Agreement, provided, that if a Lender shall not notify the Borrower that it does not desire to have prepaid a portion of its Debentures in accordance with 4.12(b), then ½ of the Excess Amount to which such Lender was entitled under Section 4.12(b) on account of the Proceeds Notice at issue may be used by the Borrower either to repay Related Party Loans or for the payment to BioTec of amounts due under the BioTec License Agreement and ½ of the Excess Amount to which such Lender was entitled under Section 4.12(b) on account of the Proceeds Notice at issue may be used by the Borrower for working capital purposes.

The Borrower shall provide the Lenders with quarterly updates not prior to release of its quarterly reports under Form 10-Q pursuant to the Exchange Act regarding its activities which relate to the receipt of proceeds in connection with the provisions of this Section 4.12.

4.13. August Agreement.  Subsequent to its prepayment obligations pursuant to Section 4.9(B) hereof, the Borrower shall use its best efforts to keep in full force and effect the August Agreement and the transactions contemplated thereby and to maintain the Borrower’s ability to require redemptions and conversions of the August Debentures until December 31, 2003.

MISCELLANEOUS

6.1. Termination.    This Agreement may be terminated prior to the Closing by the Borrower or any Lender, by written notice to the other, if the Closing has not been consummated by the third Trading Day following the date of this Agreement; provided that no such termination will affect the right of any party to xxx for any breach by the other party (or parties).

6.3. Entire Agreement.    The Transaction Documents, together with the Exhibits and Schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. At or after the Closing, and without further consideration, the Borrower will execute and deliver to the Lenders such further documents as may be reasonably requested in order to give practical effect to the intention of the parties under the Transaction Documents.

Amendments; Waivers.    No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the Borrower and each of the Lenders or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

6.6. Construction.    The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

6.7. Successors and Assigns.    This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Borrower may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Lenders. Any Lender may assign its rights under this Agreement to any Person to whom such Lender assigns or transfers any Securities.

6.8. No Third-Party Beneficiaries.    This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Related Person

26

is an intended third party beneficiary of Section 4.8 and may enforce the provisions of such Section directly against the Borrower.

6.9. Governing Law.    All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York, Borough of Manhattan. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of this Agreement), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or any of the Transaction Documents or the transactions contemplated hereby or thereby. If either party shall commence an action or proceeding to enforce any provisions of this Agreement or any Transaction Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys fees and other reasonable costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

6.10. Survival.    The representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery, exercise and/or conversion of the Securities, as applicable.

6.11. Execution.    This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature page were an original thereof.

6.12. Severability.    If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties

27

will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.13. Rescission and Withdrawal Right.    Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Lender exercises a right, election, demand or option under a Transaction Document and the Borrower does not timely perform its related obligations within the periods therein provided, then such Lender may rescind or withdraw, in its sole discretion from time to time upon written notice to the Borrower, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

6.14. Replacement of Securities.    If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Borrower shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Borrower of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.

6.15. Remedies.    In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Lenders and the Borrower will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

6.16. Payment Set Aside.    To the extent that the Borrower makes a payment or payments to any Lender pursuant to any Transaction Document or a Lender enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Borrower, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.17. Independent Nature of Lenders.   The obligations of each Lender under any Transaction Document are several and not joint with the obligations of any other Lender, and no Lender shall be responsible in any way for the performance of the obligations of any other Lender under any Transaction Document. The decision of each Lender to purchase Securities pursuant to this Agreement has been made by such Lender independently of any other Lender and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Borrower or of the Subsidiary which may have been made or

28

given by any other Lender or by any agent or employee of any other Lender, and no Lender or any of its agents or employees shall have any liability to any other Lender (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein, or in any Transaction Document, and no action taken by any Lender pursuant hereto or thereto, shall be deemed to constitute the Lenders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Lenders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Lender shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Lender to be joined as an additional party in any proceeding for such purpose.
