III. COMMERCIALIZATION; REGULATORY APPROVALS

A. Commercialization. Panacela shall, at its expense, use its commercially diligent efforts, which in any event shall not be less than the efforts Panacela uses with respect to its own proprietary products not derived from the Licensed Rights, to bring Products to market as timely and efficiently as possible consistent with sound and reasonable business practices and judgments. Such program shall likely include the preclinical and clinical development of Products at Panacela’s expense, including research and development, laboratory and clinical testing, and marketing and sales. This Agreement shall not provide to CBLI any ownership rights to any developments of Panacela not otherwise provided by separate agreements between the Parties, if any. Notwithstanding the foregoing, all business decisions shall be within the sole discretion of Panacela. CBLI acknowledges that Panacela is in the business of developing, manufacturing, marketing and selling biopharmaceutical products. Panacela shall provide CBLI written reports necessary for CBLI to satisfy its reporting obligations under the Exclusive License Agreement, including written reports on at least on a semi-annual basis detailing Panacela’s clinical, regulatory, and financial progress. CBLI understands that these reports may contain material non-public information and that to such extent such reports will be considered “Confidential Information” pursuant to Section XVIII. Nothing in this Agreement shall be construed as restricting Panacela's conduct of such business or imposing on Panacela the duty to market and/or sell Products for which royalties are payable hereunder to the exclusion of, or in preference to, any other Panacela product, or in any way other than in accordance with its normal commercial practices.

B. Regulatory Approval. Panacela shall be solely responsible for securing any federal, including U.S. Food and Drug Administration ("FDA"), state, local or foreign Regulatory Approval necessary for commercial sale of Products.

CBLI agrees that, any such Regulatory Approval made in its name will not affect the rights granted to Panacela in this Agreement. CBLI will lend assistance, including involving CCF or Other Institution as necessary, on a reasonable basis to facilitate Panacela’s acquisition of necessary Regulatory Approvals. Such assistance will include the provision to Panacela as promptly as reasonably practicable of scientific and clinical data obtained by CBLI (including from CCF or Other Institution) relating to the Licensed Rights and the Products. Panacela shall be responsible for reimbursing CBLI for any reasonable direct costs associated with such activity, including costs incurred by CBLI to CCF or Other Institution.

IV. CONSIDERATION

A. For any amounts owed to CCF under Section 4.B of the Exclusive License Agreement (the “CCF Milestones”) on account of activities under the Licensed Rights (the “Panacela Activities”), Panacela shall pay the CCF Milestones directly to CCF or its designee, as applicable, in the name of CBLI.

B. Earned Royalties. For any amounts owed to CCF under Section 4.C of the Exclusive License Agreement (the “CCF Royalties”) on account of Panacela Activities, Panacela shall pay the CCF Royalties directly to CCF or its designee, as applicable, in the name of CBLI.

C. Sublicense Royalties. For any amounts owed to CCF under Section 4.D of the Exclusive License Agreement (the “CCF Sublicense Royalties”) on account of Panacela Activities, Panacela shall pay the CCF Sublicense Royalties directly to CCF or its designee, as applicable, in the name of CBLI.

D. Accounting. Panacela shall provide CCF , CCIA and/or CBLI, as applicable a full accounting showing how any amounts owing under this Section IV have been calculated on the date of each such payment and paid. Such accounting will be on a per-country and product line, model, or trade name basis and shall be summarized in a reporting format that contains substantially similar information to the information obligations of CBLI as set out in Section 4 to the Exclusive License Agreement. Should failure by Panacela to make a required payment when due hereunder cause interest to accrue against CBLI under the Exclusive License Agreement, the corresponding balance due by Panacela hereunder shall accrue interest until paid at the same rate.

E. Currency. Except as otherwise directed, all amounts owing under this Agreement shall be paid in U.S. dollars by wire transfer to an account specified by the designated recipient. If any currency conversion shall be required in connection with the payment of royalties hereunder, such conversion shall be made at the rate used by Panacela in calculating Panacela's own revenues for financial reporting purposes.

F. Withholdings. Any withholding or other tax that Panacela or an Affiliate thereof is required by law to withhold shall be deducted from said royalties and promptly paid to the taxing authority. If royalties paid to Panacela or an Affiliate thereof by a Sublicensee on Net Sales of Products are reduced for withholding or similar taxes, the Sublicense Royalties due CCF shall be correspondingly reduced, and Panacela shall furnish CCF, CCIA and/or CBLI with proper evidence of the taxes paid.

Panacela may assign its right to receive payments hereunder.

IX. CONTEST OF VALIDITY

In the event Panacela or a third party contests the validity of any Licensed Patent, Panacela shall continue to pay royalties with respect to that patent as if such contest were not underway to an escrow agent mutually agreed to by the parties, to be held in a separate interest bearing account in accordance with the terms of a mutually acceptable escrow agreement between the parties in form and substance as is customary for such purposes, until such time as a court of last resort adjudicates the validity or invalidity of such patent.

CBLI and Panacela shall cooperate fully in any claims or suits commenced and prosecuted by either Party pursuant to this Section X.

XI. ENFORCEMENT OF LICENSED RIGHTS

A. Panacela has the right, but not the obligation, to defend the Licensed Rights (the “Enforced Rights”) against infringement, interference or opposition by other parties in any country, including by bringing any legal action for infringement or opposition or defending any counterclaim of invalidity, notice of opposition or action of a third party for declaratory judgment of non- infringement or interference. Panacela may bring or defend, or subject to CBL’s approval, which approval shall not be unreasonably withheld, conditioned or delayed, may settle any such actions solely at its own expense and through counsel of its selection; provided, however, that CBLI, CCF and the Other Institution, to the extent that the Enforced Rights are based on the rights granted by CCF or Other Institution, as the case may be, shall be entitled in each instance to participate through counsel of its selection and at its own expense. CBLIhas no obligation or responsibility with respect to any such infringement action or interference except to provide reasonable assistance to Panacela as requested, and Panacela shall reimburse CBLI and Other Institution, as the case may be, for its reasonable out-of-pocket expenses in connection with any such assistance. Panacela shall be entitled to credit against royalties payable to CBLI hereunder to the same extent that CBLI shall be entitled to credit against royalties payable to CCF or CCIA, as applicable. Any amounts entitled to be so credited and not previously credited may be carried forward. In the event of a favorable settlement or award of damages, any amounts owed to CCF under Section 11.A of the Exclusive License Agreement shall be paid directly to CCF or CCIA, as applicable, in the name of CBLI. CCF’s or CCIA’s sole financial obligation, as applicable, with respect to such litigation will be limited to the right of Panacela to credit fifty percent (50%) of its costs and expenses against royalties as provided herein.

B. In the event Panacela is permanently enjoined from exercising any of the License Rights granted hereunder pursuant to an infringement action brought by a third party, or if Panacela elects not to undertake the defense or settlement of such a claim of alleged infringement for a period of six (6) months from notice of such claim or suit, then Panacela’s rights and obligations under this Agreement with respect to said License Rights will terminate upon written notice from CBLI, subject to Section VII of this Agreement. If Panacela elects to defend any such action, then Panacela shall be entitled to credit against royalties payable to CBLI hereunder fifty percent (50%) of its out-of-pocket costs and expenses incurred in connection with such action at a rate not to exceed fifty percent (50%) of the royalties due CBLI in any Half Year. Any amounts entitled to be so credited and not previously credited may be carried forward.

XII. PATENT MARKING

Panacela shall xxxx all Products or Products’ packaging with the appropriate patent number reference in compliance with the requirements of United States law (see 35 U.S.C.§287).

C. Counterparts. This Amendment may be executed in counterparts with the same effect as if both parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together and shall constitute one and the same instrument.

XVI. INTEGRATION

This Agreement constitutes the full understanding between the parties with reference to the subject matter hereof, and no statements or agreements by or between the Parties, whether orally or in writing, except as provided for elsewhere in this Section XVII, made prior to or at the signing hereof, shall vary or modify the written terms of this Agreement. Neither Party shall claim any amendment, modification, or release from any provisions of this Agreement by mutual agreement, acknowledgment, or otherwise, unless such mutual agreement is in writing, signed by the other Party, and specifically states that it is an amendment to this Agreement.

XVII. SEVERABILITY

If any provision of this Agreement is held to be invalid, the other provisions will not be affected to the greatest extent possible consistent with the parties’ intent.

XVIII. CONFIDENTIALITY

A. Panacela acknowledges that CBLI may disclose valuable confidential information of CCF, Other Institution or CBLI to Panacela pursuant to the terms of this Agreement. CBLI acknowledges that Panacela may disclose valuable confidential information to CBLI pursuant to the terms of this Agreement. Accordingly, the Parties agree to keep any Confidential Information in confidence and not to use or disclose the same except in pursuance of the terms of this Agreement.

B. Both Parties agree to keep any information identified as confidential by the disclosing Party, confidential using methods at least as stringent as each party uses to protect its own confidential information. “Confidential Information” shall include plans and reports of Panacela, Panacela’s books and records maintained pursuant to Section VI, the Licensed Rights and all information concerning them and any other information marked confidential or accompanied by correspondence indicating such information is confidential exchanged between the parties hereto. Except as may be authorized in advance in writing by the other Party, each Party shall grant access to the Confidential Information only to its own employees involved in research relating to the subject matter of the Licensed Patents and/or manufacture or marketing of the Products, and each Party shall require such employees to be bound by confidentiality obligations substantially similar to those set forth in Article XVIII. Each Party agrees not to use any Confidential Information to its advantage and the other Party’s detriment, including, but not limited to, in the case of Panacela, claiming priority to any application serial numbers of any Licensed Mobilan Patents in any patent prosecution by Panacela. The confidentiality and use obligations set forth above apply to all or any part of the Confidential Information disclosed hereunder except to the extent that:

The recipient party can show by written record that it possessed the information prior to its receipt from the other Party;

The information was already available to the public or became so through no fault of the recipient party;

The information is subsequently disclosed to the recipient party by a third party that has the right to disclose it free of any obligations of the disclosing party; or

The information is required by law or regulation to be disclosed; provided, however, that the Party subject to such disclosure requirement has provided written notice to the other Party promptly to enable such other Party to seek a protective order or otherwise prevent disclosure of such Confidential Information.

C. The Parties agree to keep the nature, existence and terms of this Agreement confidential until first publicly announced by the Parties pursuant to a joint press release mutually approved by the Parties. The content and timing of all press releases and similar public communications regarding this Agreement and the subject matter hereof will be mutually agreed to in writing by the Parties, and neither Party may make or issue any public announcement or press release that refers to the other Party or describes any aspect of this Agreement without having first received the prior written consent of the other Party. Notwithstanding the foregoing, either Party may make any public announcement or disclosure that it reasonably believes is required by law, rule or regulation of any governmental authority or other regulatory body (including, without limitation, the SEC or the FDA).

D. Notwithstanding the provisions of this Section XVIII, Panacela shall have the right to disclose Confidential Information to its sublicensees, agents, vendors, consultants, Affiliates or other third parties (collectively, “Agents”) in accordance with this paragraph. Such disclosure shall be limited only to the Agents involved in the research, development, commercialization, manufacturing, marketing or promotion of Products. Any such Agents must agree in advance and in writing to be bound by confidentiality and non-use obligations substantially similar to those contained in this Agreement. In addition, Panacela and its Agents may make disclosure of such Confidential Information of CBLI as may be necessary in order to obtain or maintain any Regulatory Approvals, including, in connection with clinical trials, regulatory applications and filings, and otherwise.

XIX. ANTI-KICKBACK STATUTE AND XXXXX LAW COMPLIANCE

By entering into this Agreement, the parties specifically intend to comply with all applicable laws, rules and regulations, including (i) the federal anti-kickback statute (42 U.S.C. §1320a-7b) and the related safe harbor regulations; and (ii) the Limitation on Certain Physician Referrals, also referred to as the “Xxxxx Law” (42 U.S.C. §1395nn). Accordingly, no part of any consideration paid hereunder is a prohibited payment for the recommending or arranging for the referral of business or the ordering of items or services; nor are the payments intended to induce illegal referrals of business. In the event that any part of this Agreement is determined to violate federal, state, or local laws, rules, or regulations, the parties agree to negotiate in good faith revisions to the provision or provisions that are in violation.

XX. ELIGIBILITY TO PARTICIPATE IN FEDERAL HEALTH CARE PROGRAMS

By signing this agreement, Panacela hereby represents and warrants the following: (a) that is has not been debarred, excluded, suspended or otherwise determined to be ineligible to participate in any federal health care programs (collectively, “Debarment” or “Debarred”, as applicable); and (b) that it shall not knowingly employ or contract with, with or without compensation, any individual or entity (singularly or collectively, “Program Agent”) listed by a federal agency as Debarred. To comply with this provision, Panacela shall make reasonable inquiry into the status of any Program Agent contracted or arranged by Panacela to fulfill the terms of this Agreement. In the event that Panacela and/or an Program Agent thereof either (i) becomes Debarred or (ii) receives notice of action or threat of action with respect to its Debarment during the term of this Agreement, Panacela agrees to notify CBLI immediately. Panacela agrees to timely notify CBLI in the event that Panacela has identified or reasonably suspects potential violations associated with its performance under this Section, and the nature of such potential violation, to enable CBLI to take prompt corrective action. Further, in the event that Panacela or a Program Agent thereof becomes Debarred as set forth above and such Debarment shall have become final and non-appealable, this Agreement relative to such entity or individual’s participation hereunder may be terminated upon written notice.

XXI. AUTHORITY

The persons signing on behalf of each of CBLI and Panacela hereby warrant and represent that they have authority to execute this Agreement on behalf of the Party for whom they have signed.

XXII. PUBLICATION

To avoid loss of patent rights as a result of premature public disclosure of patentable material, CBLI will extend to Panacela and allow Panacela to exercise all of CBLI’s benefit and rights regarding intended publication or disclosure pertaining to the Licensed Rights.

XXIII. DISPUTE RESOLUTION

A. Disputes. The Parties recognize that disputes as to certain matters arising under or relating to this Agreement or either Party’s rights and/or obligations hereunder may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in Section XXIII.B if and when such a dispute arises between the Parties.

B. Procedures. The Parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by negotiation between executives who have the authority to settle the controversy. Either Party may give the other Party written notice of a dispute not resolved in the normal course of business. If the matter has not been resolved by such executives within sixty (60) days of a disputing Party’s notice, the Parties agree to submit the matter to mediation unless mediation is waived upon written consent of the Parties. If the matter is submitted to mediation but is not resolved through negotiation or mediation, or if the Parties waive mediation, either Party may initiate binding arbitration as provided in Section XXIII.C.

C. Arbitration. Arbitration of disputes or claims (each, a “Claim”) between the parties under this Section XXIII.C shall be administered by JAMS in accordance with its Comprehensive Arbitration Rules and Procedures. The arbitration shall be held in New York, New York. The arbitration shall be conducted by one arbitrator who is knowledgeable in the subject matter at issue in the dispute. The arbitrator will be selected by written agreement of the Parties. The arbitrator shall, within fifteen (15) days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The arbitrator shall be authorized to award compensatory damages, but shall NOT be authorized (a) to award non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (b) to award punitive or multiple damages, or (c) to reform, modify or materially change this Agreement or any other agreements contemplated hereunder; provided, however, that the damage limitations described in subsections (a) and (b) of this sentence will not apply if such damages are statutorily imposed. The arbitrator also shall be authorized to grant any temporary, preliminary or permanent equitable remedy or relief the arbitrator deems just and equitable and within the scope of this Agreement, including, without limitation, an injunction or order for specific performance. The decision of the arbitrator shall be final and binding upon the Parties. The award of the arbitrator shall be the sole and exclusive remedy of the Parties. Judgment on the award rendered by the arbitrator may be entered in any court having competent jurisdiction thereof. This Section XXIII.C shall not apply to any dispute, controversy or claim that concerns (i) the validity or infringement of a patent, trademark or copyright; or (ii) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory. Notwithstanding the foregoing, claims for injunctive relief shall not be subject to the requirements of arbitration. English shall be the language of any arbitration proceeding.

D. Costs and Awards. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrator; provided, however, that the arbitrator shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, and travel expenses), and/or the fees and costs of the arbitrator.

E. Waiver and Acknowledgement. By agreeing to this binding arbitration provision, the Parties understand that they are waiving certain rights and protections which may otherwise be available if a Claim between the Parties were determined by litigation in court, including, without limitation, the right to seek or obtain certain types of damages precluded by this provision, the right to a jury trial, certain rights of appeal, and a right to invoke formal rules of procedure and evidence.

XXIV. CONFLICT OF INTEREST

CCF maintains and adheres to a Conflict of Interest Policy. In connection therewith, Panacela represents that no CCF employees, officers or directors are consultants, employees, officers or directors of Panacela or any of its Affiliates serve on any boards or committees of or in any advisory capacity with Licensee or any of its affiliates.

XXV. COMPLIANCE WITH LAWS

A. Panacela agrees to comply with all applicable US and Foreign laws, rules, regulations and restrictions. Without limiting the foregoing, by entering into this Agreement, Panacela will comply with all applicable laws, rules and regulations including, the Foreign Corrupt Practices Act, export/import laws, security laws and regulations, currency restrictions, and tax and other applicable treaties. In the event that any part of this Agreement is determined to violate any such us or foreign, federal, state, or local laws, rules, or regulations, the Parties agree to negotiate in good faith revisions to the provision or provisions that are in violation. In the event the Parties are unable to agree to new or modified terms as required to bring the entire Agreement into compliance, either Party may terminate this agreement upon sixty (60) days' written notice to the other Party.

B. Export Control Compliance. Panacela will comply with all applicable export laws, regulations, and restrictions. In connection with the exercise of Panacela’s rights hereunder, CBLI does not represent that an export license will not be required nor that, if required, such a license will be issued. It is also understood that the transfer of certain technical data and commodities may require a license from the United States Government. CBLI will reasonably cooperate with and assist Panacela to obtain any required export licenses. However, and notwithstanding anything to the contrary herein, Panacela will be solely responsible for ensuring that all export control regulations, laws, and restrictions (“Export Laws”) are complied with in connection with this Agreement, including overseeing the activities of its Affiliates and Sublicensees in connection with any right exercised under this Agreement. If any transfer under this Agreement to any person or entity, whether private or governmental, violates any U.S. export control regulation, law or restriction, such transfer shall be void at its inception, but any such violation shall be subject to Panacela’s indemnity obligation under Article 13. Upon request, and in any event with each Report due hereunder, an officer of Panacela shall certify that Panacela and each Sublicensee and Affiliate are in compliance with and have not violated any Export Law.
