Accordingly, the Seller shall treat the sale, transfer, assignment and conveyance of the Revenue Participation Right as a sale of an “account” or a “payment intangible” (as appropriate) in accordance with the UCC, and the Seller hereby authorizes the Buyer to file financing statements (and continuation statements with respect to such financing statements when applicable) naming the Seller as the debtor and the Buyer as the secured party in respect to the Revenue Participation Right. Not in derogation of the foregoing statement of the intent of the parties hereto in this regard, and for the purposes of providing additional assurance to the Buyer in the event that, despite the intent of the parties hereto, the sale, transfer, assignment and conveyance contemplated hereby is hereafter held not to be a sale, the Seller does hereby grant to the Buyer, as security for the payment of amounts to the Buyer equal to the Purchase Price (including a market rate of return thereon) less all Royalty Payments received by the Buyer pursuant to this Agreement, a security interest in and to all right, title and interest in, to and under the Revenue Participation Right, the Royalty Payments (excluding, for the avoidance of doubt, accounts and payment intangibles (each as defined in the UCC) of the Seller) and the Product Collateral, and the Seller does hereby authorize the Buyer, from and after the Closing, to file such financing statements (and continuation statements with respect to such financing statements when applicable) in such manner and such jurisdictions as are necessary or appropriate to perfect such security interest (the “Back-Up Security Interest”).

Section 2.2 Purchase Price. At the Closing and upon the terms and subject to the conditions of this Agreement, the purchase price to be paid as consideration to the Seller for the sale, transfer, assignment and conveyance of the Revenue Participation Right to the Buyer is One Hundred Twenty-Five Million Dollars ($125,000,000) in cash (the “Purchase Price”).

Section 2.3 No Assumed Obligations, Etc. Notwithstanding any provision in this Agreement to the contrary, the Buyer is only agreeing, on the terms and conditions set forth in this Agreement, to purchase, acquire and accept the Revenue Participation Right and is not assuming any liability or obligation of the Seller of whatever nature, whether presently in existence or arising or asserted hereafter.

Following the Closing, upon at least fourteen (14) Business Days written notice and during normal business hours, no more frequently than once per calendar year, the Buyer may cause an inspection and/or audit by an independent public accounting firm reasonably acceptable to the Seller to be made of the Seller’s books of account for the three (3) calendar years prior to the audit for the purpose of determining the correctness of Royalty Payments made under this Agreement. Upon the Buyer’s reasonable request, no more frequently than once per calendar year while any Out-License remains in effect, the Seller shall use Commercially Reasonable Efforts to exercise any rights it may have under any Out-License relating to a Product to cause an inspection and/or audit by an independent public accounting firm to be made of the books of account of any counterparty thereto for the purpose of determining the correctness of Royalty Payments made under this Agreement. All of the out-of-pocket expenses of any inspection or audit requested by the Buyer hereunder (including the fees and expenses of such independent public accounting firm designated for such purpose) shall be borne solely by the Buyer, unless the independent public accounting firm determines that Royalty Payments previously paid during the period of the audit were underpaid by an amount greater than [***] of the Royalty Payments actually paid during such period, in which case such expenses shall be borne by the Seller. Any such accounting firm shall not disclose the confidential information of the Seller or any such Licensee relating to a Product to the Buyer, except to the extent such disclosure is necessary to determine the correctness of Royalty Payments or otherwise would be included in a Report. All information obtained by the Buyer as a result of any such inspection or audit shall be Confidential Information subject to ARTICLE 8. If any audit discloses any underpayments by the Seller to the Buyer, then such underpayment, shall be paid by the Seller to the Buyer within thirty (30) calendar days of it being so disclosed. If any audit discloses any overpayments by the Seller to the Buyer, then the Seller shall have the right to credit the amount of the overpayment against each subsequent quarterly Royalty Payment due to the Buyer until the overpayment has been fully applied. If the overpayment is not fully applied prior to the final quarterly Royalty Payment due hereunder, the Buyer shall promptly refund an amount equal to any such remaining overpayment.

(b) The Seller shall promptly inform the Buyer of any infringement by a Third Party of any Patent Right of which any of the individuals named in the definition of “Knowledge of the Seller” (or the successors of such Person at the Seller) becomes aware.

The Seller shall use its Commercially Reasonable Efforts to cure any material breaches by it under any In-License and shall give written notice to the Buyer upon curing any such breach. The Seller shall provide the Buyer with written notice following becoming aware of a counterparty’s material breach of its obligations under any In-License. The Seller shall not terminate any In-License without providing the Buyer prior written notice. Promptly, and in any event within [***] following the Seller’s notice to a counterparty to any In-License of an alleged breach by such counterparty under any such In-License, the Seller shall provide the Buyer a copy thereof.

Section 6.7 Out-Licenses and Permitted Sales.

(b) The Seller shall promptly (and in any event within [***]) provide the Buyer with (i) executed copies of each Out-License and Permitted Sale, and (ii) executed copies of each amendment, supplement, modification or written waiver of any material provision of an Out-License or Permitted Sale.

(e) The Seller shall provide the Buyer with written notice promptly (and in any event within [***]) following the termination of any Out-License or Permitted Sale.

Section 6.8 Restricted Indebtedness. Prior to the Minimum Return Date, the Seller shall not, and shall not permit any of its Subsidiaries to, create, incur, assume or suffer to exist any Restricted Indebtedness. As a condition to the incurrence of any secured Permitted Indebtedness for borrowed money with one or more lenders other than the holders of Indebtedness under the Athyrium Credit Agreement, either (i) the Seller shall cause such lender or lenders or any agent, representative or trustee acting on behalf of such lender or lenders to become a party to the Intercreditor Agreement in accordance with the terms thereof or (ii) the Buyer shall enter, and the Seller shall enter and cause such lender or lenders or any agent, representative or trustee acting on behalf of such lender or lenders to enter into an Other Intercreditor Agreement.

(a) The Seller shall use Commercially Reasonable Efforts to complete clinical development and Commercialize (either directly or through Licensees) (a) Orladeyo in the Direct Sales Territories for HAE, and (b) BCX9930 in the Direct Sales Territories for paroxysmal nocturnal hemoglobinuria.

The parties hereto shall use commercially reasonable efforts to give or cause to be given to the other party hereto such assistance and such information concerning the reasons for withholding or deduction (including, in reasonable detail, the method of calculation for the deduction or withholding thereof) as may be reasonably necessary to enable the Buyer or the Seller, as applicable, to claim exemption therefrom, or credit therefor, or relief (whether at source or by reclaim) therefrom, and, in each case, shall furnish the Buyer or the Seller, as applicable, with proper evidence of the taxes withheld and deducted and remitted to the relevant taxing authority. The Buyer agrees (i) to notify the Seller in writing if (A) Buyer becomes ineligible to use or deliver the Form W-8BEN-E delivered to the Seller under Section 5.2(e), or (B) the Form W-8BEN-E delivered to the Seller under Section 5.2(e) ceases to be accurate or complete, and (ii) to provide (to the extent it is legally eligible to do so) any additional Tax forms that the Seller may reasonably request.

Each of the parties further agrees that, in the event of any action for specific performance in respect of such breach of violation, it will not assert the defense that a remedy at law would be adequate.
