Item 1.01. Entry Into a Material Definitive Agreement .

On May 8, 2008, Enzo Biochem, Inc., a New York corporation (the “ Registrant ”), Enzo Life Sciences, Inc., a New York corporation and a wholly owned subsidiary of the Registrant (“ Enzo Life Sciences ”), Biomol International, Inc., a New York corporation and a newly formed wholly owned subsidiary of Enzo Life Sciences (“ Biomol ”), and Axxora (UK) Ltd., a private limited company incorporated under the laws of England and Wales and a wholly owned subsidiary of Enzo Life Sciences (“ Axxora ” and, collectively with the Registrant, Enzo Life Sciences and Biomol, the “ Buyer Parties ”), entered into a stock and asset purchase agreement dated as of May 8, 2008 (the “ Purchase Agreement ”), with Biomol International, L.P., a Pennsylvania limited partnership (the “ Seller ”), Biofiniti, L.L.C., a Pennsylvania limited liability company and the general partner of the Seller (“ Biofiniti ”), and each of the following limited partners of the Seller (collectively with the Seller and Biofiniti, the “ Seller Parties ”): Biomol Research Laboratories, Inc., a Pennsylvania corporation, Mamhead Holding Co., LLC, a Delaware limited liability company, Robert E. Zipkin, Ph.D., Ira M. Taffer, Ph.D., Paul W. Sheppard, Ph.D. and Ian M. Varndell, Ph.D.

Under the terms of the Purchase Agreement, Biomol purchased from the Seller Parties substantially all of the Seller’s U.S.-based assets and assumed certain of the Seller’s liabilities, and Axxora purchased from the Seller all of the outstanding capital stock of the Seller’s wholly owned U.K. subsidiaries, Affiniti Limited and Affiniti Research Products Limited (the “ Transaction ”). The execution of the Purchase Agreement and the closing of the Transaction occurred simultaneously on May 8, 2008.

The purchase price comprised:

$15,000,000 in cash, subject to a downward post-closing purchase price adjustment based on “Net Asset Value” (as defined in the Purchase Agreement) as of the closing date, $550,000 of which will be held in escrow for approximately 75 days to secure the payment of any downward post-closing purchase price adjustment and $1,500,000 of which will be held in escrow for 24 months to secure the payment of any indemnification obligations of the Seller Parties under the Purchase Agreement;
352,113 unregistered “restricted” (within the meaning of Rule 144 under the Securities Act of 1933, as amended (the “ Securities Act ”)) shares of the Registrant’s common stock (the “ Closing Shares ”), which number of Closing Shares is equal to $3.0 million divided by $8.52 (the volume-weighted average closing price per share of the Registrant’s common stock as reported on the New York Stock Exchange composite tape for the 10 consecutive trading-day period ending on the second trading day immediately prior to the closing date), all of which Closing Shares were issued to the Seller at closing; and
two earn-out payments of $2.5 million each (for a maximum combined total of $5.0 million), the first of which will become due and payable only if the “Adjusted Business Net Sales” and “Business EBITDA” (as those terms are defined in the Purchase Agreement) for the 12-month period ending April 30, 2009 exceed certain thresholds set forth in the Purchase Agreement, and the second of which will become due and payable only if the Adjusted Business Net Sales and Business EBITDA for the 12-month period ending April 30, 2010 exceed certain thresholds set forth in the Purchase Agreement.

The earn-out payments, if any, will be payable within approximately 75 days following the end of such 12-month periods (subject to extension), in such combination of cash and unregistered “restricted” (within the meaning of Rule 144 under the Securities Act) shares of the Registrant’s common stock (the “ Earn-Out Shares ”) as the Registrant and Enzo Life Sciences may determine in their discretion, provided that in no event will more than 50% of such earn-out payments be paid in shares of the Registrant’s common stock. For purposes of determining the aggregate number of Earn-Out Shares to be issued as the stock portion of such earn-out payments, if any, such number of shares shall be equal to (x) the dollar amount of such earn-out payment to be paid in shares of the Registrant’s common stock divided by (y) 95% of the volume-weighted average closing price per share of the Registrant’s common stock as reported on the New York Stock Exchange composite tape for the 10 consecutive trading-day period ending on the second trading day immediately prior to the date the earn-out payment is required to be made.

Under the Purchase Agreement, each of the Seller Parties agreed not to compete with the acquired business and not to hire or solicit for hire any former employees of the Seller (other than in their capacity as an employee of the combined company), in each case for a period of five years from and after the closing, with respect to each of the Seller Parties that is not a natural person, with respect to Messrs. Zipkin and Taffer, for a period of five years from and after the date of termination of their employment with the combined company, and, with respect to Messrs. Sheppard and Varndell, for a period of 18 months from and after the date of termination of their employment with the combined company.

The Purchase Agreement contains customary representations and warranties, covenants and indemnification obligations of the parties thereto as set forth therein. The representations and warranties contained in the Purchase Agreement are made as of the date of the Purchase Agreement solely to and for the benefit of the parties thereto. They may have the purpose of confirming certain due diligence matters between the parties, and may represent an allocation of risk between the parties in the context of a negotiated transaction. In addition, the representations and warranties may be qualified by information set forth in confidential disclosure schedules that the parties have exchanged in connection with their execution of the Purchase Agreement. Accordingly, investors should not rely on the representations and warranties contained in the Purchase Agreement as a characterization of the actual state of facts as of the date of the Purchase Agreement or any subsequent time.

There are no material relationships between any of the Seller Parties, on the one hand, and the Buyer Parties or any of their respective affiliates, any director or officer of the Buyer Parties, or any associate of any such director or officer, on the other hand, other than with respect to the Purchase Agreement and the ancillary agreements referred to therein and the transactions contemplated thereby.

The foregoing is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which is attached hereto as Exhibit 2.1 and is incorporated herein in its entirety by reference. The press release issued by the Registrant announcing the foregoing is attached hereto as Exhibit 99.1 to and is incorporated herein in its entirety by reference.

Item 2.01. Completion of Acquisition or Disposition of Assets .

The information set forth in Item 1.01 above is incorporated into this Item 2.01 in its entirety by reference.

Item 3.02. Unregistered Sales of Equity Securities .

The information set forth in Item 1.01 above is incorporated into this Item 3.02 in its entirety by reference.

The Closing Shares issued to Seller in connection with the Purchase Agreement were issued without registration under the Securities Act in a transaction exempt from the registration requirements of the Securities Act pursuant to Section 4(2) of the Securities Act and Rule 506 of Regulation D promulgated thereunder. The issuance of the Closing Shares was exempt from registration because it was a private sale made without general solicitation or advertising exclusively to one “accredited investor” as defined in Rule 501 of Regulation D. Further, the certificate issued to Seller bears a legend providing, in substance, that the securities represented by the certificate have been acquired for investment only and may not be sold, transferred or assigned in the absence of an effective registration statement or opinion of counsel that registration is not required under the Securities Act.

If any Earn-Out Shares are issued to Seller in connection with the Purchase Agreement, they will be issued without registration under the Securities Act in reliance on the exemption from the registration requirements of the Securities Act provided under Section 4(2) of the Securities Act and Rule 506 of Regulation D promulgated thereunder for transactions that do not involve a public offering of securities.

Item 8.01. Other Events .

On May 9, 2008, the Registrant issued a press release announcing its entry into the Purchase Agreements referred to in Item 1.01 above. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated into this Item 8.01 in its entirety by reference.

ARTICLE VI.
COVENANTS OF SELLER AND BUYER

The Seller Parties and the Buyer Parties each covenant with the other as follows:

6.1 Non-Competition

Each of the Seller Parties covenants and agrees that, other than in the case of Zipkin, Taffer, Sheppard and Varndell, in his capacity as an employee or officer of Buyer or one of its Affiliates, it or he shall not, for the Restricted Period, directly or indirectly (including by licensing or other partial rights transfers), through an affiliated or controlled Person, on its or his own behalf or as a partner, manager, member, consultant, proprietor, principal, agent, creditor, director, officer, employee, security holder (except by ownership of five percent (5%) or less of the outstanding stock of any publicly held corporation), trustee or in any other capacity, own, manage, operate, finance, control, invest, participate or engage in, lend its or his name to, lend credit to, render services or advice to, or devote any endeavor or effort to, any business that is the same as, substantially similar to, or in competition with, the Business, in the United States, Canada, the United Kingdom or in any other country in which the products or services of the Business are marketed (including via the internet), distributed or sold. For the purposes of this Section 6.1, the “ Restricted Period ” shall mean:

(i) with respect to Seller, Biofiniti, Biomol Research and Mamhead, the period of five (5) years from and after the Closing Date;

(ii) with respect to each of Zipkin and Taffer, the period from and after the Closing Date until the fifth (5 ^th ) anniversary of the date of termination of their respective employment with the Buyer or one of its Affiliates; and

(b) Enforceability . The terms of this Section 6.1 are a material inducement to the Buyer Parties to enter into this Agreement and the Ancillary Agreements to which they are a party and to consummate the transactions contemplated hereunder and thereunder. The Parties acknowledge and agree that the restrictive covenants contained herein are reasonable under the circumstances and further agree that the covenants contained in this Section 6.1 should be interpreted in such a manner as to be effective and valid under applicable law. In the event any portion of this Section 6.1 shall be held to be illegal or unenforceable, the remainder of this Section 6.1 shall remain in full force and effect. If any of the restrictions contained in this Section 6.1 shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, such provision shall be construed by limiting or reducing it so as to be enforceable to the maximum extent compatible with applicable law.

6.2 Employee Matters .

(a) Buyer shall offer at-will employment to all employees currently employed by a Seller Party listed on Schedule 6.2 attached hereto. Each of the Seller Parties will use reasonable best efforts to assist Buyer in the hiring of such employees. Upon execution of this Agreement, Seller shall notify each employee listed on Schedule 6.2 in writing that, by reason of the sale of the Business, their employment with a Seller Party is terminated as of the Closing Date and that Buyer is offering such employees employment. Any such employees actually employed by Buyer or its Affiliates immediately following the Closing, other than Zipkin, Taffer, Sheppard and Varndell, are referred to in this Agreement as “ Rehired Employees .” To the

extent that service is relevant for purposes of eligibility and vesting (and, in order to calculate the amount of any sick days, severance, layoff and similar benefits, but not for purposes of pension benefit accruals) under any retirement plan, employee benefit plan, program or arrangement established or maintained by Buyer or any of its Affiliates for the benefit of the Buyer’s employees, such plan, program or arrangement, shall, to the extent permitted by the terms and conditions thereof, credit such Rehired Employees for service earned on and prior to the Closing Date with a Seller Party, in addition to service earned with Buyer or any of Buyer’s Affiliates after the Closing Date. In addition to the foregoing, as of the Closing Date, the Buyer Parties shall provide each Rehired Employee, at the time of hiring, with initial compensation (but excluding benefits and any incentive or equity-based compensation) at least as favorable as the compensation (but excluding benefits and any incentive or equity-based compensation) provided to such employees by a Seller Party as of the date of this Agreement. Seller shall issue to each terminated employee (including all Rehired Employees) a final paycheck on the Closing Date, containing their salary through the Closing, all accrued, unused paid time off, and any other wages, overtime, severance pay, bonuses, change-in-control payment, other incentive compensation, commissions, expense reimbursement, or any other compensation that was earned, accrued, or payable prior to or as a result of the Closing.

(b) Notwithstanding anything to the contrary contained herein, the Seller Parties shall be solely responsible for all of the Employee Plans at any time maintained, contributed to or required to be contributed to by any Seller Party or any ERISA Affiliate and all Liabilities thereunder. Buyer shall not assume any of the Employee Plans at any time maintained, contributed to or required to be contributed to by any Seller Party or any ERISA Affiliate or any Liability thereunder. The Seller Parties and their respective Affiliates (other than the Affiniti Companies) shall hold the Buyer Parties, their Affiliates (which for purposes hereof, shall include the Affiniti Companies) and their assigns harmless from and against any and all obligations to current or former employees relating to their employment in connection with the operation of the Business prior to the Closing. The Seller Parties shall take all necessary and appropriate action, if any, to comply on or prior to the Closing Date with any federal, state, local and foreign laws regarding termination of the employees.

(c) Nothing contained in this Agreement shall confer upon any Rehired Employee any right with respect to continuance of employment by Buyer or any of its Affiliates, nor shall anything herein interfere with the right of Buyer or any of its Affiliates to terminate the employment of any of the Rehired Employees at any time, with or without cause, or restrict Buyer or any of its Affiliates in the exercise of its independent business judgment in modifying any of the terms and conditions of the employment of the Rehired Employees.

(d) No provision of this Agreement shall create any third party beneficiary rights in any Rehired Employee, any beneficiary or dependents thereof, or any collective bargaining representative thereof, with respect to the compensation, terms and conditions of employment and benefits that may be provided to any Rehired Employee by Buyer or any of its Affiliates or under any benefit plan which Buyer or any of its Affiliates may maintain.

6.3 Consents . If the Third Party Consent of any Person required for the assignment of any Assumed Contract or Lease, other than those Assumed Contracts and Leases set forth on Schedule 8.5 (with respect to which the provisions of this Section 6.3 shall not be applicable), or

any Permit or any claim or right or any benefit arising thereunder or resulting therefrom that is being assigned to a Buyer Party hereunder is not obtained prior to the Closing, or if an attempted assignment thereof would be ineffective or would affect the rights thereunder so that such Buyer Party would not receive all such rights, the Seller Parties will, at the expense of the Seller Parties, (i) use their reasonable best efforts to obtain all such Third Party Consents not previously obtained as soon as practicable after the Closing and (ii) cooperate with the Buyer Parties to provide to such Buyer Party the benefits under any such Assumed Contract, Lease, Permit or any claim or right, including enforcement for the benefit of Buyer of any and all rights of the Seller Parties against a third party thereto arising out of the Default, cancellation or termination by such third party or otherwise. Notwithstanding anything in this Agreement to the contrary, nothing contained in this Section 6.3 shall in any way change, modify, limit or affect the conditions set forth in Sections 8.5 and 8.6 of this Agreement.

6.4 Reporting Company Status . For a period until the earlier of (a) the first anniversary of the Closing Date and (b) a Change in Control of Parent, Parent shall file with the SEC all reports required to be filed pursuant to the Exchange Act and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules and regulations thereunder would permit such termination. For the purposes of this Section 6.4, a “ Change in Control ” shall mean any transaction or series of transactions, circumstance or event, pursuant to which any Person after the Closing Date obtains the possession, directly or indirectly, of the de facto or de jure power to direct or cause the direction of management policies of Parent, whether through the ownership of voting securities, by contract or otherwise.

The termination of the representations, warranties, covenants and agreements provided in this Agreement, the Ancillary Agreements, or in any attachment, Exhibit, the Disclosure Schedule, certificate, document or list delivered by any such Party pursuant hereto, shall not affect the rights of a Party in respect of any Claim (including the rights and remedies set forth in Section 9.4), provided that such Claim shall be made in a writing received by the Seller (in the case of a Claim made by a Buyer Party) or received by the Buyer (in the case of a Claim made by a Seller Party) prior to the expiration of the applicable survival period provided in this Section 9.3 (whether or not formal legal action shall have been commenced based upon such Claim), in which case the representations, warranties, covenants or agreements that are the subject of such Claim shall survive with respect to such Claim until such Claim is finally resolved.

(i) any breach or inaccuracy of any representation or warranty of any of the Buyer Parties contained in or made pursuant to this Agreement, the Ancillary Agreements to which any Buyer Party is a party (excluding the Employment Agreements), or in any attachment, Exhibit, certificate, document or list delivered by any Buyer Party pursuant hereto (without regard and without giving effect to any “materiality”, “Parent Material Adverse Effect” or similar qualification contained in any such representation or warranty);

(iv) any fees, expenses or other payments incurred or owed by any Buyer Party to any agent, broker, investment banker or other firm or Person retained or employed by it in connection with the transactions contemplated by this Agreement and the Ancillary Agreements.

The term “ Damages ” as used in this Section 9.4 is not limited to matters asserted by third parties against a Seller Indemnified Party or a Buyer Indemnified Party, but includes Damages incurred or sustained by a Seller Indemnified Party or a Buyer Indemnified Party in the absence of third party claims. Payments by a Buyer Indemnified Party of amounts for which such Buyer Indemnified Party is indemnified hereunder, and payments by a Seller Indemnified Party of

amounts for which such Seller Indemnified Party is indemnified, shall not be a condition precedent to recovery. The Seller Parties’ obligation to indemnify the Buyer Indemnified Parties, and the Buyer Parties’ obligation to indemnify the Seller Indemnified Parties, shall not limit any other rights, including rights of contribution (except as provided in Section 9.4(g)(x) below), which any Party may have under statute or common law.

(c) Cooperation . The indemnified party shall cooperate in all reasonable respects with the indemnifying party and such attorneys in the investigation, trial and defense of such lawsuit or action and any appeal arising therefrom; provided , however , that the indemnified party may, at its own cost, participate in the investigation, trial and defense of such lawsuit or action and any appeal arising therefrom. The Parties shall cooperate with each other in any notifications to insurers.

(d) Defense of Claims . If a claim for Damages (a “ Claim ”) is to be made by a Person entitled to indemnification hereunder against the indemnifying party, the Person claiming such indemnification shall give written notice (a “ Claim Notice ”) to the indemnifying party promptly after the Person entitled to indemnification becomes aware of any fact, condition or event which may give rise to Damages for which indemnification may be sought under this Section 9.4. If any lawsuit or enforcement action is filed against any Person entitled to the benefit of indemnity hereunder, written notice thereof shall be given promptly to the indemnifying party (and in any event within fifteen (15) calendar days after the service of the citation or summons). The failure of any indemnified party to give timely notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the indemnifying party demonstrates actual material prejudice or material damage caused by such failure. After such notice, if the indemnifying party shall acknowledge in writing to the indemnified party that the indemnifying party shall be obligated under the terms of its indemnity hereunder in connection with such lawsuit or action, then the indemnifying party shall be entitled, if it so elects at its own cost, risk and expense, (i) to take control of the defense and investigation of such lawsuit or action where such lawsuit or action involves only money damages and does not seek injunctive or other equitable relief, (ii) to employ and engage attorneys of its own choice to handle and defend the same (which attorneys shall be reasonably acceptable to the indemnified party), and (iii) to compromise or settle such claim, which compromise or settlement shall be made only with the written consent of the indemnified party, such consent not to be unreasonably withheld. Notwithstanding the foregoing, the indemnified party shall have the right to employ separate counsel at the indemnifying party’s expense and to control its own defense of such lawsuit or action to the extent that there are reasonable legal defenses available to such indemnified party or to other indemnified parties that are of a material benefit to such indemnified party and are different from or additional to those available to the indemnifying party; provided , however , that the indemnifying party shall not be required to pay for more than one such additional counsel for all indemnified parties in connection with any Claim. If the indemnifying party fails to assume the defense of such claim within thirty (30) calendar days after receipt of the Claim Notice, the indemnified party against which such claim has been asserted will (upon delivering notice to such effect to the indemnifying party) have the right to undertake, at the indemnifying party’s cost and expense, the defense, compromise or settlement of such claim on behalf of and for the account and risk of the indemnifying party; provided , however , that such claim shall not be compromised or settled without the written consent of the indemnifying party, which consent shall not be unreasonably withheld. In the event the indemnified party assumes the defense of the

claim, the indemnified party will keep the indemnifying party reasonably informed of the progress of any such defense, compromise or settlement. The indemnifying party shall be liable for any settlement of any action effected pursuant to and in accordance with this Section 9.4 and for any final judgment (subject to any right of appeal), and the indemnifying party agrees to indemnify and hold harmless an indemnified party from and against any Damages by reason of such settlement or judgment. If the indemnified party refuses its consent under clause (iii) above of this Section 9.4(d) to a bona fide offer of settlement which the indemnifying party wishes to accept, where the terms and conditions of such settlement (x) include a release in form and substance reasonably satisfactory to the indemnified party from all Liability in respect of such Claim and (y) do not, in the reasonable judgment of the indemnified party, impose any burden, restraint, cost, Liability, duty or other obligation on or otherwise adversely affect or have the potential to adversely affect the indemnified party, the indemnified party may continue to pursue such matter, free of any participation by the indemnifying party, at the sole expense of the indemnified party. In such event, the obligation of the indemnifying party to the indemnified party shall be equal to the lesser of (A) the amount of the offer of settlement which the indemnified party refused to accept plus the costs and expenses of the indemnified party prior to the date the indemnifying party notified the indemnified party of the offer of settlement, and (B) the actual out-of-pocket amount the indemnified party is obligated to pay as a result of the indemnified party’s continuing to pursue such matter. The indemnifying party shall be entitled to recover from the indemnified party any additional expenses incurred by the indemnifying party as a result of the decision of the indemnified party to pursue such matter. If there shall be any conflicts between the provisions of this Section 9.4(d) and Section 9.8(c), the provisions of Section 9.8(c) shall control with respect to Tax contest claims.

(e) Buyer Parties’ Right of Offset . Anything in this Agreement to the contrary notwithstanding, but subject to Section 9.6 and subsection (ii) of Section 9.4(f), in the event that any Seller Party is obligated to indemnify any Buyer Indemnified Party pursuant to any provision of this Section 9.4, the Buyer Parties may (but shall not be obligated to), in addition to any other right or remedy, receive, withhold, purchase or repurchase, sell or foreclose on, as applicable, the following, and set off such amounts, securities or property so received or withheld by the Buyer Parties against such indemnification obligation, in the following order of priority:

FIRST, the entire amount in the Indemnity Escrow Account; and

SECOND, any other amounts, securities or property otherwise due any Seller Party from a Buyer Party (including any payments in cash or securities that may become due and payable to Seller pursuant to Section 2.6 or Section 9.11) .

For purposes of clarification, the Buyer Parties shall not be entitled to offset any amounts, securities or property otherwise due any Seller Party from a Buyer Party (including any payments in cash or securities that may become due and payable to Seller pursuant to Section 2.6 or Section 9.11) against any indemnification obligation of the Seller Parties under this Agreement, if the sum of (i) the total dollar amount of such indemnification obligation of the Seller Parties plus (ii) the total dollar amount of Damages with respect to all then pending or unresolved indemnity Claims of the Buyer Indemnified Parties under this Agreement does not exceed the remaining balance, if any, of the funds contained in the Indemnity Escrow Account. If the sum of (i) the total dollar amount of such indemnification obligation of the Seller Parties plus

(ii) the total dollar amount of Damages with respect to all then pending or unresolved indemnity Claims of the Buyer Indemnified Parties under this Agreement exceeds the remaining balance, if any, of the funds contained in the Indemnity Escrow Account, then, the Buyer Parties shall be entitled to offset any amounts, securities or property otherwise due any Seller Party from a Buyer Party (including any payments in cash or securities that may become due and payable to Seller pursuant to Section 2.6 or Section 9.11) against any such indemnification obligation of the Seller Parties under this Agreement, but only to the extent of such excess.

Neither the exercise of nor the failure to exercise such right of offset shall be deemed to be or construed as a waiver or election of remedies by the Buyer Parties or prejudice or impair the concurrent or subsequent exercise or enforcement of any other rights or remedies available to them.

(f) Limitations .

(i) Subject to Section 9.4(f)(iii), neither the Buyer Parties nor the Seller Parties shall be liable under this Section 9.4 for any Damages until either any individual amount otherwise due the indemnified party exceeds $50,000, in which case the indemnifying party shall, subject to Section 9.4(f)(ii), be liable for all Damages (including those incurred prior to exceeding $50,000), or the aggregate amount otherwise due to the indemnified party exceeds an accumulated total of $100,000, in which case the indemnifying party shall, subject to Section 9.4(f)(ii), be liable for all Damages (including those incurred prior to exceeding $100,000); provided , however , that (A) these limitations shall apply only to the extent the indemnified party is entitled to indemnification exclusively under Section 9.4(a)(i) or Section 9.4(b)(i), and (B) these limitations shall not apply with respect to Damages arising out of a breach of any representation or warranty contained in Sections 4.1, 4.2, 4.3, 4.5(a) (first sentence only), 4.5(b), 4.11, 4.20, 4.27, 4.29, 4.30, 4.31, 4.32, 5.1, 5.2, 5.3, 5.5, 5.14 and 5.15, for which the indemnifying party shall be liable for all Damages.

9.4(b)(iv), in each case set forth in clauses (x), (y) and (z) hereof, for which the indemnifying party shall be liable for all Damages.

(iii) Notwithstanding anything to the contrary in this Agreement, nothing set forth in this Agreement (including the limitations on indemnification amount set forth in clauses (i) and (ii) of this Section 9.4(f) and the durational limitations set forth in Section 9.3) shall limit the rights, remedies or claims of any party (or the Liability of any party) for fraud, willful or intentional breach or gross negligence.

(g) Miscellaneous Indemnity Provisions .

(i) The indemnifying parties’ indemnification obligations herein are intended solely for the benefit of the indemnified parties, and are in no way intended to, nor shall they, constitute an agreement for the benefit of, or be enforceable by, any other Person.

(ii) Any payment by the Seller Parties of any Damages of the Buyer Indemnified Parties shall be deemed to be a reduction in the Purchase Price for Tax purposes.

(iii) In determining the amount of any Damages payable by an indemnifying party pursuant to Section 9.4, such amount shall be reduced by the amount of any refund received by the indemnified parties of Taxes paid by them, to the extent such refund relates solely to the Damages or to the payments made pursuant to such Damages. In the event an indemnifying party has paid for any Damages which is later subject to reduction due to the receipt of a Tax refund relating solely to the Damages, the indemnified parties shall promptly pay the amount of such Tax refund to indemnifying party at the time actually received by the relevant indemnifying party.

(iv) With respect to any indemnification obligation of the Seller Parties pursuant to any Damages related to the failure to collect accounts receivable of Seller which constituted a breach of Section 4.22 above, Buyer shall deliver and assign to Seller, on the date any such Damages are satisfied by a related payment of Damages to a member of the Buyer Indemnified Parties, without any further payment or consideration, such uncollected accounts receivable of Seller to which the Damages relates.

(v) For purposes of determining the amount of any Damages payable by an indemnifying party pursuant to Section 9.4, such amount shall be reduced by the amount of any insurance proceeds actually received by the indemnified party in respect of the Damages (net of any deductible amounts or associated incremental premiums that the indemnified party reasonably expects to incur as a result of the claim). In the event the indemnifying party has paid for any Damages which later the indemnified party receives any insurance proceeds with respect thereto, the indemnified party shall promptly pay the amount of such insurance proceeds to the indemnifying party at the time actually received by the indemnified party (net of any deductible amounts) up to the amount of the Damages for which the indemnifying party has paid.

(vi) Prior to any indemnification by the Seller Parties for any Damages related to the provisions of Section 4.22 above or otherwise in respect of the accounts receivable of Seller, Buyer shall (i) apply all collections for accounts receivable against the accounts

receivable of a particular payor existing on the Closing Date on a first-billed, first-paid basis so that such collections are first applied against the earliest-date receivable of the applicable payor; provided , however , that if the payor designated a specific invoice or invoices to be paid or if Buyer otherwise reasonably determines that the payor intended a different application of the payment where the payment amount matches a specific outstanding invoice, then the payment shall be applied to the specific invoice or invoices so designated or intended; and (ii) use commercially reasonable efforts to collect its accounts receivable, including the sending of demand letters and other similar practices.

(vii) Nothing herein shall be deemed to prevent an indemnified party from making a Claim hereunder for potential or contingent claims or demands; provided that the Claim Notice sets forth the specific basis for any such contingent claim to the extent then feasible and the indemnified party has reasonable grounds to believe that such a claim may be made.

(viii) No Party shall be liable under this Section 9.4 for any Damages relating to any matter to the extent that such matter directly resulted in an adjustment to the Purchase Price pursuant to Section 2.5.

(ix) In no event shall any Party be liable for any special, multiple, exemplary or punitive damages arising under any legal or equitable theory or arising under or in connection with this Agreement, all of which are hereby excluded by agreement of the Parties regardless of whether or not any Party to this Agreement has been advised of the possibility of such damages, except to the extent an indemnified party is required to pay such damages in connection with a third party claim.

9.5 Indemnification Holdback Amount as Initial Source of Payment . The Parties agree and acknowledge that the Indemnification Holdback Amount shall not be the Buyer Indemnified Parties’ exclusive method of receiving indemnification from the Seller Parties pursuant to this Agreement, but that no amount shall be payable directly from the Seller Parties to any Buyer Indemnified Party in respect of any indemnification obligation of the Seller Parties under this Agreement until there are no further funds remaining in the Indemnity Escrow Account following disbursements therefrom in accordance with Section 9.6 below.

9.6 Release and Payment of Indemnification Holdback Amount . The Escrow Agent shall hold and pay the Indemnification Holdback Amount pursuant to the Escrow Agreement and this Agreement. The Indemnification Holdback Amount shall be used (i) to satisfy

The foregoing shall not be deemed to be or construed as a waiver or election of remedies by the Buyer Parties.

(c) If, as of the Expiration Date, a Buyer Indemnified Party has delivered a Claim Notice to any Seller Party that is pending or unresolved, Buyer and Seller shall give joint written instructions to the Escrow Agent on the Expiration Date to (i) retain an amount equal to the lesser of (A) the balance, if any, of the funds and all other amounts then remaining on deposit in the Indemnity Escrow Account and (B) the amounts asserted in writing by Buyer to be claimed to be owing to the Buyer Indemnified Parties under Section 2.5 and/or Section 9.4 of this Agreement, together with all interest and other amounts earned thereon, and (ii) pay to Seller an amount in cash equal to the amount, if any, by which the then remaining balance of the funds and all other amounts then remaining on deposit in the Indemnity Escrow Account exceeds (A) the amounts so asserted in writing by Buyer to be claimed to be owing to the Buyer Indemnified

Parties under Section 2.5 and/or Section 9.4 of this Agreement, together with all interest and other amounts earned thereon, and (B) all fees, costs and expenses due and payable by Seller to the Escrow Agent under Section 2.4(d) hereof and under the Escrow Agreement.

If the amount of the Damages in respect of one or more Claims to which the Buyer Indemnified Parties shall have been determined to be entitled exceeds the balance, if any, of the funds contained in the Indemnity Escrow Account, the Buyer Parties shall be entitled to have recourse directly against the Seller Parties to recover the balance of such Damages, subject to the limitations set forth in this Agreement. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by the Buyer Parties.

(e) Within two (2) Business Days after the date on which final resolution of all indemnity Claims brought prior to and pending or unresolved as of the Expiration Date (which Claims are the subject of one or more Claim Notices referred to in Section 9.6(c) above) has occurred, either by mutual written agreement of Buyer and Seller or a final order of a court of competent jurisdiction, Buyer and Seller shall give joint written instructions to the Escrow Agent to (i) pay to Buyer an amount equal to the Damages in respect of all such Claims to which the Buyer Indemnified Parties shall have been determined to be entitled (to the extent not previously paid), together with all interest and other amounts earned thereon, and thereafter (ii) pay to the Seller an amount in cash equal to the then remaining balance of the funds and all other amounts then remaining on deposit in the Indemnity Escrow Account, if any, less all fees, costs and expenses due and payable by Seller to the Escrow Agent under Section 2.4(d) hereof and under the Escrow Agreement, which amounts shall be paid by the Escrow Agent in accordance with the procedures set forth in the Escrow Agreement. If the amount of the Damages in respect of any one or more Claims to which the Buyer Indemnified Parties shall have been determined to be entitled exceeds the balance, if any, of the funds contained in the Indemnity Escrow Account, the Buyer Parties shall be entitled to have recourse directly against the Seller Parties to recover the balance of such Damages, subject to the limitations set forth in this Agreement. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by the Buyer Parties.

(f) For the avoidance of doubt, all interest and other amounts earned under the Escrow Agreement on the Indemnification Holdback Amount in the Indemnity Escrow Account shall be paid to Seller, on the one hand, and/or to Buyer, on the other hand, in proportion to the total amount of the Indemnification Holdback Amount paid to such Party as above provided.

Each Party hereto agrees that it will not unreasonably withhold, delay or condition any such consent or clearance.

10.10 Confidential Information

(a) No Disclosure . The Parties acknowledge that the transaction described herein is of a confidential nature and shall not be disclosed except to consultants, advisors and Affiliates, or as required by applicable Regulations of the SEC or any relevant stock exchange or market or by order or decree of a court or regulatory body having jurisdiction over such Party or in connection with such Party’s or its agent’s or Affiliate’s enforcement of any rights it may have at law or equity, until such time as the Parties make a public announcement regarding the transaction as provided in Section 10.10.

(b) Preservation of Confidentiality . In connection with the negotiation of this Agreement, the preparation for the consummation of the transactions contemplated hereby, and the performance of obligations hereunder, each of the Buyer Parties and the Seller Parties (a “ receiving party ”) acknowledges that it will have access to confidential information relating to the Seller Parties or the Buyer Parties, respectively (a “ disclosing party ”), including technical, manufacturing or marketing information, ideas, methods, developments, inventions, improvements, business plans, trade secrets, scientific or statistical data, diagrams, drawings, specifications or other proprietary information relating thereto, together with all analyses, compilations, studies or other documents, records or data prepared by the disclosing party or its Representatives which contain or otherwise reflect or are generated from such information (“ Confidential Information ”). The term “Confidential Information” does not include information received by a receiving party in connection with the transactions contemplated hereby which (i) is or becomes generally available to the public other than as a result of a disclosure by a receiving party or its Representatives, (ii) was within a receiving party’s possession prior to its being furnished to such receiving party by or on behalf of the disclosing party in connection with the transactions contemplated hereby, provided that the source of such information was not known by such receiving party to be bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the disclosing party or any other Person with respect to such information or (iii) becomes available to such receiving party on a

non-confidential basis from a source other than a disclosing party or any of its respective Representatives, provided that such source is not bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the disclosing party or any other Person with respect to such information.

(c) Each receiving party shall treat all Confidential Information as confidential, preserve the confidentiality thereof and not disclose any Confidential Information, except to its Representatives, attorneys and Affiliates who need to know such Confidential Information in connection with the transactions contemplated hereby. Each receiving party shall use all reasonable efforts to cause its Representatives to treat all Confidential Information as confidential, preserve the confidentiality thereof and not disclose any Confidential Information.

(d) If a receiving party or any of its Representatives or Affiliates is requested or required (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process) or is required by operation of law to disclose any Confidential Information, such receiving party shall provide the disclosing party with prompt written notice of such request or requirement, which notice shall, if practicable, be at least 48 hours prior to making such disclosure, so that the disclosing party may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement. If, in the absence of a protective order or other remedy or the receipt of such a waiver, the receiving party or any of its Representatives is nonetheless, in the opinion of counsel, legally compelled to disclose Confidential Information, then the receiving party may disclose that portion of the Confidential Information which such counsel advises is legally required to be disclosed, provided that the receiving party uses its reasonable efforts to preserve the confidentiality of the Confidential Information, whereupon such disclosure shall not constitute a breach of this Agreement.

10.11 Remedies of Buyer Parties . The Seller Parties acknowledge and agree that the Assets and the Affiniti Shares are unique and not readily available, and that remedies at law, including monetary damages, will be inadequate in the event of a breach by any of the Seller Parties in the performance of its obligations under this Agreement and the Ancillary Agreements to which any of them are a party. Accordingly, the Seller Parties acknowledge that, in addition to all other remedies to which the Buyer Parties are entitled under Section 9.4 hereof, the Buyer Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and the Ancillary Agreements and to enforce the terms of this Agreement and the Ancillary Agreements by a decree of specific performance pursuant to which the breaching Party is ordered to affirmatively carry out its obligations under this Agreement and the Ancillary Agreements to which it is a party, without proof of actual damages and without any requirement for the securing or posting of any bond. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by the Buyer Parties, and the Buyer Parties expressly reserve any and all rights and remedies available to each of them under this Agreement (including those contained in Section 9.4 hereof), which rights and remedies shall be cumulative and the exercise or enforcement of one or more rights or remedies shall not prejudice or impair the concurrent or

subsequent exercise or enforcement of any other rights or remedies available to them. Except as provided in this Section 10.11 (and except for remedies that cannot be waived as a matter of law), the indemnification provisions and procedures contained in Section 9.4 shall constitute the sole and exclusive monetary remedy of the Parties hereto with respect to any Damages resulting from, arising out of or in connection with the failure of any of the representations and warranties contained in this Agreement, the Ancillary Agreements to which any Seller Party is a party (excluding the Employment Agreements), or in any attachment, Exhibit, the Disclosure Schedule, certificate, document or instrument delivered by any Seller Party pursuant hereto, to be true and correct or the breach of any covenants, agreements or undertaking contained in this Agreement, the Ancillary Agreements to which any Seller Party is a party (excluding the Employment Agreements), or in any attachment, Exhibit, the Disclosure Schedule, certificate, document or instrument delivered by any Seller Party pursuant hereto, in each case other than with respect to fraud, willful or intentional breach or gross negligence.

10.12 Attorneys’ Fees . If any Party to this Agreement brings an action to enforce its rights under this Agreement or any Ancillary Agreement, the prevailing Party shall be entitled to recover its costs and expenses, including reasonable attorneys’ fees, incurred in connection with such action, including any appeal of such action.

Notwithstanding the immediately preceding sentence, a party may commence any Action in a court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts.

(b) Each Party agrees that for any Action among the Parties arising in whole or in part under or in connection with this Agreement and the Ancillary Agreements, such Party shall bring Actions only in the City of New York. Each Party further waives any claim and shall not assert that venue should properly lie in any other location within the selected jurisdiction.

(c) Each Party hereby (i) consents to service of process in any Action among the Parties arising in whole or in part under or in connection with this Agreement or any Ancillary Agreement in any manner permitted by New York law; (ii) irrevocably designates C.T.

10.14 Waiver of Jury Trial . TO THE EXTENT NOT PROHIBITED BY APPLICABLE LEGAL REQUIREMENTS THAT CANNOT BE WAIVED, THE PARTIES HEREBY WAIVE, AND COVENANT THAT THEY WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT, THE ANCILLARY AGREEMENTS OR ANY OF THE CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE ITS RIGHT TO TRIAL BY JURY. ANY PROCEEDING WHATSOEVER AMONG THEM RELATING TO THIS AGREEMENT, THE ANCILLARY AGREEMENTS OR ANY OF THE CONTEMPLATED TRANSACTIONS SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

10.15 Construction . The Parties have participated jointly in the negotiation and drafting of this Agreement and the Ancillary Agreements. In the event an ambiguity or question of intent or interpretation arises, this Agreement and the Ancillary Agreements shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement and the Ancillary Agreements. Any contract or statute defined or referred to herein or in any contract that is referred to herein means such contract or statute as from time to time amended, modified or supplemented, including (in the case of contracts) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein.

All dollar amounts are expressed in United States dollars, and, unless otherwise expressly provided, all amounts payable hereunder shall be paid in United States dollars.

10.16 Disclosure Schedule . The inclusion of any item in any section of the Disclosure Schedule shall not constitute an admission that a violation, right of termination, Default, Liability or other obligation of any kind exists with respect to such item, but rather is intended only to respond to certain representations and warranties in this Agreement and to set forth other information required by this Agreement. Also, the inclusion of any matter in the Disclosure Schedule does not constitute an admission as to its materiality as it relates to any provision of this Agreement. Information disclosed in or for one section of the Disclosure Schedule shall be deemed disclosed in all other sections of the Disclosure Schedule to the extent applicable only if it is reasonably clear from the text of the disclosure in the section of the Disclosure Schedule where such information appears that such information is relevant to such other section of the Disclosure Schedule, and the mere listing (or inclusion of a copy) of a document or other item shall not be deemed adequate to disclose an exception to a representation or warranty made in this Agreement, unless the representation or warranty has to do with the existence of the document or other item itself.

BIOMOL is a privately owned global producer of over 3,300 specialty life science products for the areas of signal transduction, lipid research, apoptosis, neuroscience and drug discovery, with a research focus in the field of functional proteomics.

“This acquisition is in line with our strategy to grow Enzo Life Sciences, backed by our extensive IP estate, both organically and through acquisition,” said Barry Weiner, Enzo President. “Coupling BIOMOL with our acquisition of Axxora Life Sciences less than a year ago, we have succeeded in transforming Enzo Life Sciences into a global manufacturer and marketer of reagents and systems spanning a wide spectrum of scientific applications. BIOMOL has annual revenues tracking nearly $11.5 million, and annual growth of about 9%; this will help to speed Enzo’s annual overall run rate toward the $100 million level. BIOMOL has a strong record of revenue and profit growth, and is expected to become accretive to Enzo’s earnings, prior to purchase accounting adjustments. Moreover, Enzo’s strong international presence will serve to enhance the worldwide marketing efforts of the BIOMOL product line.”

“BIOMOL is a major addition to our life science business. Founded in 1983, it has an experienced management team, a proprietary product line, and facilities in Pennsylvania and in the UK that complement our existing manufacturing and marketing capabilities,” added Mr. Weiner. “Their manufacturing capabilities should serve to enhance Enzo Life Sciences’ operating margins. Moreover, its UK subsidiaries, Affiniti Limited and Affiniti Research Products Limited, are accredited under the ISO9001:2000

international quality management standard, providing Enzo with the ability to supply raw materials under the most rigorous quality standards.”

With this acquisition, Enzo Life Sciences now has US operations in New York, Pennsylvania and California, and overseas facilities in Switzerland, the UK and Belgium, as well as more than 50 distributors worldwide.

The purchase price of $18 million is comprised of $15 million in cash and $3 million in unregistered stock, in addition to earn-outs over the next two years. BIOMOL’s founders and senior management will remain actively involved with Enzo Life Sciences.

“We at BIOMOL are very pleased to join Enzo, and to further extend its already considerable life sciences capabilities,” said Dr. Robert E. Zipkin, President of BIOMOL, and one of its founders. “In growing our company we have developed what we call the BIOMOL advantage, including cutting edge signal transduction products, innovative research tools, superior laboratory tested quality products, and outstanding technical support by scientists who understand product applications. We look with great anticipation to combining our operations with Enzo Life Sciences to expand our success to date.”

BIOMOL’s product offerings include enzymes and enzyme inhibitors, substrates, peptides, antibodies, and all-inclusive, easy-to-use assay systems. The Company currently has approximately 50 employees in its US and UK facilities.
