The license granted herein shall not include any rights to the Licensed Enzo Patents other than those expressly provided by this section. No license or immunity is granted under this Agreement by Enzo, either directly or by implication, estoppel, or otherwise, to any Third Party acquiring Licensed Hologic Products for the modification or combination by such Third Party of Licensed Hologic Products with other items, including without limitation for resale. Notwithstanding the foregoing and for the avoidance of doubt, the license granted herein extends to a Third Party’s use of Licensed Hologic Products (such as Hologic’s Analyte Specific Reagents and/or General Purpose Reagents), in the ordinary manner in their ordinary course of use, alone or in combination with other product(s) to offer for sale or sell testing services, but only to the extent that Hologic’s own conduct with respect to such Third Party would give rise to a colorable claim against Hologic for direct or indirect infringement under 35 U.S.C. § 271 but for the license granted to Hologic herein. For the further avoidance of doubt, no license shall extend to any Third Party for any act that would give rise to an independent claim of infringement of the Licensed Enzo Patents against such Third Party.

It is understood that Grifols’ and its Affiliates’ providing factual statements regarding its products in response to a validly propounded subpoena will not be considered as assisting in the context as used above.

2.15 No Other Rights. No rights are granted under any patents except as expressly provided herein, whether by implication, estoppel or otherwise. No right to grant covenants, rights, sublicenses, or to become a foundry for Third Parties is granted under this Agreement. The Parties agree that, except as expressly set forth herein, the licenses, releases, standstill, and covenants set forth in this Agreement (including Section 2) expressly exclude any methods, systems, products, services and/or components of any Third Party.

The Parties acknowledge and agree that this Agreement is enforceable according to its terms with respect to final dismissal with prejudice of all claims in the Litigations.

3.4 No Admission Of Liability. This Agreement is the result of a compromise and settlement for the purpose of avoiding the expense, inconvenience, and uncertainty of additional or continued litigation, and will not at any time be considered as an admission of liability or responsibility, or lack thereof, on the part of Enzo, Hologic, or Grifols.

4.2 Termination. If Hologic fails to make the Hologic Payment set forth in Section 3.1 in the time frame required by Section 3.1, then Enzo may terminate this Agreement immediately upon further written notice to that effect with respect to Hologic and the license, covenants, standstill, and releases granted by Section 2 of this Agreement with respect to Hologic shall immediately terminate, be deemed null and void ab initio, and be of no force and effect.

6.5 Governing Law / Jurisdiction. This Agreement and matters connected with the performance thereof shall be construed, interpreted, applied and governed in all respects in accordance with the laws of the United States of America and the State of Delaware, without reference to conflict of laws principles. Enzo, Hologic, and Grifols agree (a) that all disputes and litigation regarding

The Parties hereby waive any challenge to the jurisdiction or venue of the Court over these matters.

6.6 Sophisticated Parties Represented By Counsel. Each Party warrants and represents that (i) it is a sophisticated party represented at all relevant times during the negotiation and execution of this Agreement by counsel of its choice, and that it has executed this Agreement with the consent and on the advice of such independent legal counsel, (ii) it and its counsel have determined through independent investigation and robust, arm’s-length negotiation that the terms of this Agreement shall exclusively embody and govern the subject matter of this Agreement, (iii) it investigated the facts pertinent to this Agreement as it deemed necessary, (iv) no other Person or Party, nor any agent or attorney of a Party, made any promise, representation or warranty whatsoever, express or implied, not contained in this Agreement concerning the subject matter of this Agreement to induce it to execute this Agreement, (v) it has not executed this Agreement in reliance on any promise, representation or warranty whatsoever, express or implied, not contained in this Agreement concerning the subject matter of this Agreement, and (vi) it has not executed this Agreement in reliance on any promise, representation or warranty not contained herein.

6.7 Bankruptcy. The Parties acknowledge and agree that all releases, rights, covenants, and licenses granted by Enzo under or pursuant to this Agreement are, and will otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, as amended (the “Bankruptcy Code”), rights of and to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The Parties agree that, notwithstanding anything else in this Agreement, Hologic and its Affiliates, and Grifols and its Affiliates, as the licensees or recipients of such intellectual property rights under this Agreement, will retain and may fully exercise all of their rights and elections under the Bankruptcy Code (including, without limitation, Hologic’s and its Affiliates’, and Grifols’ and its Affiliates’, right to the continued enjoyment of the rights and licenses granted by Enzo under this Agreement).

6.8 No Laundering. The Parties understand and acknowledge that the licenses, covenants, and releases granted to Hologic and its Affiliates, and Grifols and its Affiliates, by Enzo hereunder are intended to cover only the bona fide products and services of Hologic, Grifols, and their respective Affiliates and are not intended to cover patent laundering activities (i.e., activities that are undertaken solely for the purpose of improperly extending licensed and other rights to cover any activity of any Third Party acting outside the scope of Hologic’s, Grifols’, or their respective Affiliates’, licensed and otherwise covered activities). The Parties further agree that a purchase of a product from a supplier and resale of such product in substantially the same form back to the

same supplier is not licensed under this Agreement. Nothing in this Agreement shall be construed to license sham sales or sham service contracts executed by Hologic or any of its Affiliates, or Grifols or any of its Affiliates, with any Third Party solely for the purpose of improperly extending licensed rights to cover any activity of any Third Party acting outside the scope of Hologic’s (or its Affiliates’) or Grifols’ (or its Affiliates’) licensed activities.

6.9 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable, such provision shall be limited or eliminated to the minimum extent necessary so that the remainder of this Agreement will continue in full force and effect and be enforceable. The Parties agree to negotiate in good faith an enforceable substitute provision for any invalid, illegal or unenforceable provision that most nearly achieves the intent of such provision.

6.10 Entire Agreement. The Parties hereby agree that (i) this is an enforceable agreement; (ii) this Agreement constitutes the entire and only understanding of each of them with respect to the subject matter of the Agreement, and merges, supersedes and cancels all previous agreements and understandings, whether oral or written, with respect to the subject matter of the Agreement; (iii) no oral explanation or oral information by any Party hereto shall alter the meaning or interpretation of this Agreement; (iv) the terms and conditions of this Agreement may be altered, modified, changed or amended only by a written agreement that identifies itself as an amendment to this Agreement and is executed by duly authorized representatives of each of them; (v) the language of this Agreement has been approved by counsel for each of them, and shall be construed as a whole according to its fair meaning; and (vi) none of them (nor their respective counsel) shall be deemed to be the draftsman of this Agreement in any action which may hereafter arise with respect to the Agreement.

6.11 Modification; Waiver. No modification or amendment to this Agreement, nor any waiver of any rights, will be effective unless assented to in writing by the Party to be charged, and the waiver of any breach or default will not constitute a waiver of any other right hereunder or any subsequent breach or default.

6.12 Construction; Language. Any rule of construction to the effect that ambiguities are to be resolved against the drafting Party will not be applied in the construction or interpretation of this Agreement. As used in this Agreement, the words “include” and “including” and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by the words “without limitation.” The terms “will” and “shall” are used synonymously. The headings in this Agreement will not be referred to in connection with the construction or interpretation of this Agreement. This Agreement is in the English language only, which language shall be controlling in all respects, and all notices under this Agreement shall be in the English language.

6.13 Counterparts. This Agreement may be executed in counterparts or duplicate originals, all of which shall be regarded as one and the same instrument, and which shall be the official and governing version in the interpretation of this Agreement. This Agreement may be executed by facsimile signatures or other electronic means and such signatures shall be deemed to bind each Party as if they were original signatures.

6.14 Further Assurances. Each Party shall execute, acknowledge and deliver such further documents and instruments and perform such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be signed below by their respective duly authorized officers.
