5.2.1           Currency. All payments to be made under this Agreement shall be made in United States dollars, unless expressly specified to the contrary herein.

5.2.2           Payment Method. Amounts due under this Agreement shall be paid in immediately available funds, by means of wire transfer to an account identified by COH.

5.2.3           Withholding of Taxes. Licensee may withhold from payments due to COH amounts for payment of any withholding tax that is required by law to be paid to any taxing authority with respect to such payments.

Rosenwald or Michael S. Weiss no longer holds a senior management position of Licensee both individuals must remain materially involved with the oversight and management of the development of Licensed Products during such period; provided further that in the event of the death of either of Dr. Rosenwald or Mr. Weiss, Licensee will be excused from observing this Section 6.1(a) with regard to the decedent;

(c)          in conducting activities contemplated under this Agreement, it shall comply in all material respects with all applicable laws and regulations including, without limitation, those related to the manufacture, use, labeling importation and marketing of Licensed Products and Licensed Services; and

(d)          Licensee had obtained and after the date hereof will obtain all authorizations necessary for the issuance of the COH Shares and the Common Stock issuable to COH upon conversion of the COH Shares issuable pursuant to this Agreement and/or the Charter prior to the issuance of such COH Shares and in any event prior to the issuance of any Qualifying Stock or the consummation of a Change of Control and covenants that all such shares issued on or prior to the date hereof are, and those issued after the date hereof will be, validly issued, fully paid and non-assignable and free of restrictions on transfer, other than restrictions on transfer under state and federal securities laws.

ARTICLE 7: INTELLECTUAL PROPERTY; PATENT PROSECUTION, MAINTENANCE AND ENFORCEMENT.

7.1         Patent Prosecution, Maintenance and Enforcement.

(a)          COH shall be responsible for the preparation, filing, prosecution, and maintenance of all Spacer Patent Rights, using counsel of its choice. COH will timely provide Licensee with copies of all relevant documentation relating to such prosecution and Licensee shall keep such information confidential. In addition, COH shall instruct the patent counsel prosecuting Spacer Patent Rights to (i) copy Licensee on patent prosecution documents that are received from or filed with the United States Patent and Trademark Office and foreign equivalent, as applicable; (ii) if requested by Licensee, provide Licensee with copies of draft submissions to the USPTO prior to filing; and (iii) give reasonable consideration to the comments and requests of Licensee or its patent counsel, provided that (a) COH reserves the sole right to make all final decisions with respect to the preparation, filing, prosecution and maintenance of such patent applications and patents; and (b) the patent counsel remains counsel to COH (and shall not jointly represent Licensee unless requested by Licensee and approved by COH, and an appropriate engagement letter and conflict waiver are in effect). All patents and patent applications in Spacer Patent Rights, to the extent assignable in whole or in part to COH, shall be assigned to COH.

(b)          COH will not unreasonably refuse to amend any patent application in Spacer Patent Rights to include claims reasonably requested by Licensee to protect the products contemplated to be sold by Licensee under this Agreement. If Licensee informs COH of other countries or jurisdictions in which it wishes to obtain patent protection with respect to the Spacer Patent Rights, COH shall prepare, file, prosecute and maintain patent applications in such counties and any patents resulting therefrom (and, for the avoidance of doubt, such patent applications and patents shall be deemed included in the Spacer Patent Rights). On a country by country and patent by patent basis, Licensee may elect to surrender any patent or patent application in Spacer Patent Rights in any country upon sixty (60) days advance written notice to COH. Such notice shall relieve Licensee from the obligation to pay for future patent costs but shall not relieve Licensee from responsibility to pay patent costs incurred prior to the expiration of the sixty (60) day notice period. Such U.S. or foreign patent application or patent shall thereupon cease to be a Spacer Patent Right hereunder, Licensee shall have no further rights therein and COH shall be free to license its rights to that particular U.S. or foreign patent application or patent to any other party on any terms.

(c)          Each Party shall promptly provide written notice to the other in the event it becomes aware of any actual or probable infringement of any of the Spacer Patent Rights in or relevant to the Field or of any Third Party claim regarding the enforceability or validity of any Spacer Patent Rights (“Infringement Notice”). Licensee shall, in cooperation with COH, use reasonable efforts to terminate infringement without litigation.

(d)          If infringing activity has not been abated within ninety (90) days following the date the Infringement Notice takes effect, then Licensee may, following consultation with COH, in its sole discretion and at its sole expense, take action against any alleged infringer or in defense of such any claim, provided, that Licensee has exclusive rights under this Agreement. Any recovery obtained by Licensee as the result of legal proceedings initiated and paid for by Licensee pursuant to this subsection (d), after deduction of Licensee’s reasonable out-of-pocket expenses incurred in securing such recovery, shall be deemed to be Net Sales of Licensed Products and/or Licensed Services in the calendar quarter in which such recovery was received and royalties shall be due and payable thereon accordingly.

(e)          If COH is involuntarily joined in a suit initiated by Licensee, then the Licensee will pay any costs incurred by COH arising out of such suit, including but not limited to, reasonable legal fees of counsel that COH selects and retains to represent it in the suit.

(f)          In the event that Licensee declines either to cause such infringement to cease (e.g., by settlement or injunction) or to initiate and thereafter diligently maintain legal proceedings against the infringer other than as part of a mutually agreed upon bona fide strategy, developed with the guidance of outside patent counsel, to preserve the Spacer Patent Rights, COH may, in its sole discretion and at its sole expense, take action against such alleged infringer or in defense of any such Third Party claim. Any recovery obtained by COH as the result of any such legal proceedings shall be for the benefit of COH only.

7.2         Trademarks. Licensee shall be responsible for the selection, registration, maintenance, and defense of all trademarks for use in connection with the sale or marketing of Licensed Products and Licensed Services in the Field in the Territory (the “Marks”), as well as all expenses associated therewith. All uses of the Marks by Licensee or a Sublicensee shall comply in all material respects with all applicable laws and regulations (including those laws and regulations particularly applying to the proper use and designation of trademarks in the applicable countries). Licensee shall not, without COH’s prior written consent, use any trademarks or house marks of COH (including the COH corporate name), or marks confusingly similar thereto, in connection with Licensee commercialization of Licensed Products or Licensed Services under this Agreement in any promotional materials or applications or in any manner implying an endorsement by COH of Licensee or the Licensed Products or Licensed Services. Licensee shall own all Marks.

7.3         Challenge to the Spacer Patent Rights by Licensee.

(a)          COH may terminate this Agreement and, notwithstanding Section 3.3, above, all Sublicenses issued hereunder, upon written notice to Licensee in the event that Licensee or any of its Affiliates or Sublicensees directly or indirectly asserts a Patent Challenge. “Patent Challenge” means any challenge in a legal or administrative proceeding to the patentability, validity or enforceability of any of the Spacer Patent Rights (or any claim thereof), including by: (a) filing or pursuing a declaratory judgment action in which any of the Spacer Patent Rights is alleged to be invalid or unenforceable; (b) citing prior art against any of the Spacer Patent Rights, filing a request for or pursuing a re-examination of any of the Spacer Patent Rights (other than with COH’s written agreement), or becoming a party to or pursuing an interference; or (c) filing or pursuing any re-examination, opposition, cancellation, nullity or other like proceedings against any of the Spacer Patent Rights; but excluding any challenge raised as a defense against a claim, action or proceeding asserted by COH against Licensee, its Affiliates or Sublicensees. In lieu of exercising its rights to terminate under this Section 7.3(a) COH may elect upon written notice to increase the payments due under all of Section 4 by * percent (*%), which election will be effective retroactively to the date of the commencement of the Patent Challenge. Licensee acknowledges and agrees that this Section 7.3(a) is reasonable, valid and necessary for the adequate protection of COH’s interest in and to the Spacer Patent Rights, and that would not have granted to Licensee the licenses under those Spacer Patent Rights, without this Section.

(b)          Payment of COH Patent Expenses. The Parties acknowledge that, prior to the Original Effective Date, COH provided to Licensee documentation of historic expenses incurred by COH with respect to the drafting, prosecution and maintenance of the Spacer Patent Rights. In consideration of such historic expenditures by COH, the Parties acknowledge and agree that Licensee has reimbursed COH for such expenses within thirty (30) days of the Original Effective Date.

(c)          After the Original Effective Date, COH shall provide to Licensee an annual invoice and reasonably detailed documentation with respect to COH’s out-of-pocket expenses incurred with respect to such prosecution and maintenance for the previous year. Licensee shall reimburse COH for * percent of such expenses within thirty (30) days after receipt of such invoice and documentation.

7.4           Marking. Licensee and its Sublicensees shall mark all Licensed Products and all materials related to Licensed Services in such a matter as to conform with the patent laws of the country to which such Licensed Products are shipped or in which such products are sold and such Licensed Services performed.

The indemnities set forth in this Article 10 are subject to the condition that the Party seeking the indemnity shall forthwith notify the indemnifying Party on being notified or otherwise made aware of a liability, claim, suit, action or expense and that the indemnifying Party defend and control any proceedings with the other Party being permitted to participate at its own expense (unless there shall be a conflict of interest which would prevent representation by joint counsel, in which event the indemnifying Party shall pay for the other Party’s counsel); provided, that, the indemnifying Party may not settle the liability, claim, suit, action or expense, or otherwise admit fault of the other Party or consent to any judgment, without the written consent of the other Party (such consent not to be unreasonably withheld). Notwithstanding the foregoing, no delay in the notification of the existence of any claim of Loss shall cause a failure to comply with this Section 10.3 as long as such delay shall not have materially impaired the rights of the indemnifying Party.

10.4       Insurance.

(a)          Within thirty (30) days following the Effective Date, Licensee shall procure at its sole expense and provide to COH evidence of comprehensive or commercial general liability insurance (contractual liability included) with limits of at least: (i) each occurrence, $*; (ii) products/completed operations aggregate, $*; (iii) personal and advertising injury, $*; and general aggregate (commercial form only), $*.

(b)          The foregoing policies will provide primary coverage to COH and shall name the COH Indemnitees as additional insureds, and shall remain in effect during the term of this Agreement and for * years following the termination or expiration of the term of this Agreement. The COH Indemnitees shall be notified in writing by Licensee not less than thirty (30) days prior to any modification, cancellation or non-renewal of such policy. Licensee’s insurance must include a provision that the coverages will be primary and will not participate with nor will be excess over any valid and collective insurance or program of self-insurance carried or maintained by the COH Indemnitees. Such insurance coverage shall be maintained with an insurance company or companies having an A.M. Best’s rating (or its equivalent) of A-XII or better.

(c)          Licensee expressly understands that the coverage limits in Section 10.4(a) do not in any way limit the Licensee’s liability.

10.5         LIMITATION ON DAMAGES. NOTWITHSTANDING ANYTHING CONTAINED IN THIS AGREEMENT TO THE CONTRARY, EXCEPT IN RELATION TO LICENSEE’S INDEMNIFICATION OBLIGATIONS UNDER SECTION 10.1 AND ANY BREACH BY LICENSEE OF ARTICLE 11: (I) IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY SPECIAL, PUNITIVE, CONSEQUENTIAL, INDIRECT, OR INCIDENTAL DAMAGES (INCLUDING LOSS OF PROFITS, COSTS OF PROCURING SUBSTITUTE GOODS, LOST BUSINESS OR ENHANCED DAMAGES FOR INTELLECTUAL PROPERTY INFRINGEMENT) WHETHER BASED UPON BREACH OF WARRANTY, BREACH OF CONTRACT, NEGLIGENCE, STRICT LIABILITY IN TORT OR ANY OTHER LEGAL THEORY, AND (II) IN NO EVENT SHALL COH BE LIABLE TO LICENSEE FOR AN AGGREGATE AMOUNT IN EXCESS OF TWO-THIRDS OF THE TOTAL CONSIDERATION PAID TO COH HEREUNDER.
