6.8 Withholding Taxes. Royalties and milestone payments shall be paid by Biosense to Rexahn, after deduction of any applicable withholding taxes. Prior to any payment by Biosense to Rexahn, Biosense shall provide to Rexahn any forms required to attest Rexahn’s fiscal domiciliation in order to allow Biosense to claim application of the reduced rate of withholding tax provided for in any applicable bilateral fiscal convention. Rexahn shall promptly return such forms to Biosense. In the event Rexahn fails to promptly return such forms duly filled and signed, Biosense shall declare and pay withholding tax at the common law rate of the applicable corporate income tax, and such tax shall then be deducted from the corresponding payment by Biosense to Rexahn. Biosense shall pay withholding tax to the proper taxing authority and proof of payment of such tax shall be secured and sent to Rexahn as evidence of such payment. If, in the opinion of either Party, the provisions of this Section 6.8 become extremely burdensome, the Parties agree to meet and discuss such other options as may be available to them. For the avoidance of doubt, Rexahn shall be responsible for its own compliance with Applicable Laws in respect of amounts paid to Rexahn under this Agreement and Biosense shall not be liable for any failure by Rexahn to comply with such Applicable Laws provided that such failure is not due to Biosense’s breach of its obligations under this Section 6.8 or any other provision of this Agreement.

6.9 Audit. Biosense shall keep and maintain for [***] years complete and accurate records of sales of Licensed Products in sufficient detail to allow Rexahn to confirm the accuracy of royalties paid hereunder. Rexahn shall have the right during such [***] year period to appoint at its expense an independent certified public accountant reasonably acceptable to Biosense to audit its relevant records for the purpose of verifying reports provided by Biosense under Section 6.6. Biosense shall make its records available for audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon [***] calendar days written notice from Rexahn. Such audit right shall not be exercised by Rexahn more than once in any Calendar Year and the records for a [***] month period may not be audited more than once. All records made available for audit shall be deemed to be Confidential Information of Biosense, except as may be used as evidence of breach of this Agreement. The results of each audit, if any, shall be binding on both Parties absent manifest error. Rexahn shall bear the full cost of such audit, except in the event that the results of the audit reveal an underpayment of royalties to Rexahn under this Agreement of [***] percent ([***]%) or more over the period being audited, in which case reasonable audit fees for such examination shall be paid by Biosense. The audits conducted by Rexahn shall not interfere with the ordinary business operations of Biosense in any material respect.

6.10 Currency. With respect to sales of the Licensed Product invoiced in Dollars, the Net Sales and the amounts due hereunder will be expressed in Dollars. With respect to sales of Licensed Products invoiced in a currency other than Dollars, the gross sales, Net Sales and royalties payable shall be expressed in the currency of the invoice issued by the Party making the sale together with the Dollar equivalent of the royalty payable and the equivalent in the currency used for calculating the applicable royalty rates, calculated using the rate of exchange published in the Wall Street Journal for such currency on the last Business Day of the relevant Calendar Quarter.

6.11 Interest on Late Payment. Any undisputed amount owed by one Party to the other Party under this Agreement that is not paid within the applicable time period set forth herein shall accrue interest at the rate of [***] ([***]%) percent per year from the dates and in the amounts that the undisputed amounts were incurred, or, if lower, the highest rate permitted under Applicable Laws. Where the late payment is caused by the Party that is owed the payment, including for reasons such as failure to communicate in a timely manner changes to bank details, or failure to respond to communications from the Party owing the payment regarding the interpretation or dispute of the terms of such payment, then no interest will be payable by the Party owing the payment.

In such event, Biosense shall keep Rexahn fully informed about such Action and shall consult with Rexahn before taking any major steps during the conduct of such Action. Rexahn shall provide all reasonable cooperation to Biosense in connection with such Action. Biosense shall not take any position with respect to, or compromise or settle, such Action in any way that is reasonably likely to directly and adversely affect the scope, validity or enforceability of the Licensed IP without Rexahn’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

7.3.4 Right to Representation. Each Party shall have the right to participate and be represented by counsel that it selects, in any Action instituted under Section 7.3.2 or Section 7.3.3 by the other Party. If a Party with the right to initiate an Action to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such Action, then the Party with the right to initiate an Action may name the other Party as plaintiff in such Action or may require the Party with standing to initiate such Action at the expense of the other Party; provided, that if Rexahn has informed Biosense that it would not proceed with such Action on the opinion of competent counsel, Biosense may not require Rexahn to initiate such Action.

7.3.5 Cooperation. In any Action instituted under this Section 7.3, the Parties shall cooperate with and assist each other in all reasonable respects.

A settlement or consent judgment or other voluntary final disposition of a suit under this Section 7.3 may be entered into without the consent of the Party not bringing the suit; provided, that such settlement, consent judgment or other disposition does not (i) admit the invalidity or unenforceability of the relevant Patent in the Licensed IP, or (ii) result in any adverse impact on the Party not bringing the suit; and provided, further that any rights granted under the relevant Patent to continue the infringing activity in such settlement, consent judgment or other disposition shall be limited to those rights that the granting Party otherwise has the right to grant.

7.4 Defense of Claims Brought by Third Parties.

ARTICLE 12.

TERM AND TERMINATION

12.1 Term; Expiration. The term of this Agreement (the “Term”) shall begin on the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 12, shall expire on a Licensed Product-by-Licensed Product and country-by-country or region-by region basis on the expiration of the last Valid Claim covering a Licensed Product.

12.2 Termination for Cause.

12.2.1 Termination for Material Breach. Either Party (the “Non-breaching Party”) may, without prejudice to any other remedies available to it at law or in equity, terminate this Agreement in the event the other Party (the “Breaching Party”) shall have materially breached or defaulted in the performance of any of its material obligations under this Agreement and such default shall have continued for [***] calendar days after written notice thereof was provided to the Breaching Party by the Non-breaching Party, such notice describing with particularity and in detail the alleged material breach. Any such termination of this Agreement under this Section 12.2.1 shall become effective at the end of such [***] calendar day period, unless the Breaching Party has either (a) cured any such breach or default prior to the expiration of such [***] calendar day period, or (b) if such breach is not susceptible to cure within such [***] calendar day period, the Breaching Party has, within such [***] calendar day period, provided to the Non-breaching Party a written plan that is reasonably calculated to effect a cure and such plan has been accepted by the Non-breaching Party. Where the Non-breaching Party has accepted any such plan in accordance with the preceding sentence, the Non-breaching Party may terminate this Agreement immediately upon written notice to the Breaching Party if the Breaching Party subsequently fails to carry out such plan. The right of either Party to terminate this Agreement as provided in this Section 12.2.1 shall not be affected in any way by such Party’s waiver or failure to take action with respect to any previous default.

12.2.2 Disagreement. If the Parties reasonably and in good faith disagree as to whether there has been a material breach, the Party which seeks to dispute that there has been a material breach may contest the allegation in accordance with Section 13.1.

12.2.3 Termination Due to Patent Challenge. Rexahn may terminate this Agreement immediately if Biosense or any of its Affiliates or Sublicensees of the Patents included in the Licensed IP directly or indirectly initiate or prosecute any lawsuit or any other civil or administrative proceeding, or the making of any claim or counterclaim, of any kind in any court, tribunal, agency or governmental entity anywhere in the world challenging the validity or enforceability of any Patent licensed or sublicensed to it under this Agreement by Rexahn.

12.2.4 Termination For Failure to Pay License Fee. Rexahn may terminate this Agreement immediately upon written notice to Biosense if Biosense fails to pay any installment of the License Fee on or before the relevant Payment Due Date or on such other date mutually agreed by both Parties in writing. For clarity, unless Rexahn elects otherwise, Section 12.2.1 shall not apply to any such failure by Biosense to timely pay any installment of the License Fee in accordance with Section 6.1 and there shall be no cure period with respect to such failure.

12.3 Termination for Insolvency. In the event that either Party (or, in the case of Biosense, an Affiliate of Biosense that holds the IND or a Regulatory Approval for RX-3117 or a Licensed Product in the Territory) makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act in any state or country or has any such petition filed against it which is not discharged within [***] calendar days of the filing thereof, then the other Party may terminate this Agreement effective immediately upon written notice to such Party. In connection therewith, all rights and licenses granted under or pursuant to any section of this Agreement are and shall otherwise be deemed to be for purposes of Section 365(n) of Title 11, United States Code (the “Bankruptcy Code”) licenses of rights to “intellectual property” as defined in Section 101(56) of the Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code. Upon the bankruptcy of any Party, the non-bankrupt Party shall further be entitled to a complete duplicate of, or complete access to, any such intellectual property, and such, if not already in its possession, shall be promptly delivered to the non-bankrupt Party, unless the bankrupt Party elects to continue, and continues, to perform all of its obligations under this Agreement.

12.4 Termination for Safety Issue. Either Party may terminate this Agreement upon written notice to the other Party in the event of a Safety Issue. Any notice of termination due to a Safety Issue pursuant to this Section 12.4 must be delivered to the non-terminating Party within [***] days of the terminating Party determining such Safety Issue exists.

12.5 Termination for Trial Failure. Biosense may terminate this Agreement with respect to the Lead Indication or any Additional Indication (such terminated indication, the “Relevant Indication”) for which Biosense has obtained an Expanded License if the global or the Chinese Registration Enabling Clinical Trial for RX-3117 for the Relevant Indication fails to meet its primary endpoints and the results of such Registration Enabling Clinical Trial are not sufficient to support Regulatory Approval of the Licensed Product for the Relevant Indication in China. Any notice of termination pursuant to this Section 12.5 must be delivered to Rexahn within [***] days of the availability of the initial tables and listings for the relevant Registration Enabling Clinical Trial. For clarity, the terms of this Agreement relating to indications other than the Relevant Indication shall remain in full force and effect.

12.6 Effects of Termination.

12.6.1 Termination by Rexahn for Cause or Insolvency or by Either Party for a Safety Issue or by Biosense for a Trial Failure. In the event of termination of this Agreement by Rexahn pursuant to Section 12.2 or Section 12.3, by either Party pursuant to Section 12.4 or by Biosense with respect to the Relevant Indication pursuant to Section 12.5, the following terms shall apply:

(a) all rights and licenses granted to Biosense by Rexahn under this Agreement shall terminate;

(d) upon the request of Rexahn, Biosense shall promptly transfer to Rexahn, or to a designee of Rexahn, all regulatory filings made with Regulatory Authorities in the Territory in connection with RX-3117 for the Lead Indication, the Initial Study Indications or any other Additional Indication, including all INDs and any foreign equivalents thereto filed in China or other countries or regions within the Territory; and

(e) with respect to any ongoing Clinical Trials of RX-3117 in the Territory: (i) if Rexahn notifies Biosense that it intends to continue any such ongoing Clinical Trials, then each Party shall cooperate with the other Party to facilitate the orderly transfer to Rexahn or its designee of the conduct of any such Clinical Trials as soon as reasonably practicable after the effective date of termination, and until such time as the conduct of such Clinical Trials has been successfully transferred to Rexahn or its designee, Biosense shall continue such Clinical Trials[***]; or (ii) if Rexahn notifies Biosense that it does not intend to continue any such ongoing Clinical Trials, or if this Agreement is terminated by either Party for a Safety Issue, then each Party shall cooperate with the other Party to wind down in accordance with Applicable Laws any ongoing Clinical Trials of RX-3117.

For clarity, if Biosense terminates this Agreement with respect to a Relevant Indication pursuant to Section 12.5, then the provisions of this Section 12.6.1 shall only apply to the extent applicable to the terminated Relevant Indication.

12.6.2 Termination by Biosense for Cause or Insolvency. In the event of a termination of this Agreement by Biosense pursuant to Section 12.3 or pursuant to Section 12.2.1, the following terms shall apply:

(a) all rights and licenses granted to Rexahn by Biosense under this Agreement, if any, shall terminate;

(b) the Parties shall have no further obligation to perform any activities under this Agreement other than as provided for or referenced in this Section 12.6.2 or in Section 12.7;

(d) if Biosense elects to obtain the license described in Section 12.6.2(c) above, then Biosense shall be responsible at its sole cost and in its sole discretion for completing or winding down any ongoing Clinical Trials of RX-3117 in the Territory in accordance with Applicable Laws; provided, that Rexahn shall have no obligation to Biosense under this Agreement to continue to conduct any global Registration Enabling Clinical Trial for RX-3117 for the Lead Indication; and

(e) if Biosense does not elect to obtain the license described in Section 12.6.2(c) above, then Biosense shall be responsible at its sole cost for promptly winding down any ongoing Clinical Trials of RX-3117 in the Territory in accordance with Applicable Laws.

12.7 Accrued Rights; Surviving Provisions of this Agreement.

12.7.1 Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration including the payment obligations under ARTICLE 6 hereof and any and all damages arising from any breach hereunder. Such termination or expiration shall not relieve any Party from obligations which are expressly indicated to survive termination of this Agreement.

12.7.2 The provisions of Sections 2.12 (for [***] years after the date of termination or expiration), 4.5, 6.9, 10.4, 10.5, 12.6 and this Section 12.7, ARTICLES 8, 9, 11 and 13, as well as any applicable definitions in ARTICLE 1 and any other provisions which are expressed to survive termination or expiration or which are required to give effect to such termination or expiration, shall survive the termination or expiration of this Agreement for any reason, in accordance with their respective terms and conditions, and for the duration stated, and where no duration is stated, shall survive indefinitely.

13.2.3 Arbitration Procedure. The arbitration shall be administered by the American Arbitration Association (“AAA”) and be held in New York, New York, United States under the commercial arbitration rules of the AAA.

The arbitrators 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 an injunction or order for specific performance. The award of the arbitrators shall be the sole and exclusive remedy of the Parties (except for those remedies set forth in this Agreement), the Parties hereby expressly agree to waive the right to appeal from the decisions of the arbitrators, and there shall be no appeal to any court or other authority (government or private) from the decision of the arbitrators.

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 arbitrators; provided, 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), unless an arbitration award provides otherwise.

13.2.5 Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, a Party may seek a temporary restraining order or a preliminary injunction from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the decision of the arbitrators on the ultimate merits of any dispute.

Neither Biosense nor Rexahn shall be liable for failure of or delay in performing obligations set forth in this Agreement, and neither shall be deemed in breach of its obligations, if such failure or delay is due to any occurrence beyond the reasonable control of a Party that (a) prevents or substantially interferes with the performance by such Party of any of its obligations hereunder and (b) occurs by reason of any act of God, flood, fire, explosion, earthquake, strike, lockout, labor dispute, casualty or accident, or war, revolution, civil commotion, act of terrorism, blockage or embargo, or any injunction, law, order, proclamation, regulation, ordinance, demand or requirement of any government or of any subdivision, authority or representative of any such government (a “Force Majeure”).
