(ii) Third Party Royalties. If the Manufacturing, Development or Commercialization of the Product by the Parties in accordance with this Agreement would, but for a license from such Third Party, infringe on such Third Party Patents, any royalties or other payments due to Third Parties pursuant to a license acquired by Auxilium then the royalty may be reduced by up to [**]% of such royalty to compensate for payments to such Third Parties but in no event shall royalties payable to BTC be reduced by more than [**] percent ([**]%) in any case.

** CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND WILL BE FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST.

(iii) Payment of Royalties. Royalties under this Agreement shall be paid within thirty (30) days in the case of no sublicense and sixty (60) days in case of royalties received from a Sublicensee, following the last day of the calendar quarter in which the royalties and other amounts are received by Auxilium.

(iv) Reporting on Royalties. With respect to Auxilium Territory, Auxilium shall report to BTC Net Sales of Products on a country-by-country basis and where such information is available, on an Indication-by-Indication basis. With respect to Partner Territory, Auxilium shall use commercially reasonable efforts to obtain Net Sales of Products on a country-by-country basis and where such information is available, on an Indication-by-Indication basis.

(b) Supply Price.

(i) Supply Price. In event BTC exercises the Supply Option, the Supply Agreement shall afford Auxilium supply terms for Year 1 that are not less favorable than the average price afforded to Auxilium by the Back-Up Suppliers for the year immediately preceding the Supply Date and supply terms for each successive year that are not less favorable than the average price afforded to Auxilium by the Back-Up Suppliers for each preceding year as applicable.

(ii) Adjustments to Supply Price.

(A) Most Favored Customer. Notwithstanding anything in this Agreement to the contrary, if at any time during the Term BTC sells or provides products including Enzyme as an active ingredient to any customer for commercial use at rates more favorable than those accorded to Auxilium, BTC shall promptly offer Auxilium the benefit of such more favorable terms and conditions or rates, which, upon acceptance, shall be retroactive to the date that such more favorable terms and conditions were first effective for such other customer. In order for Auxilium to receive more favorable cost rates, Auxilium must accept the same basic business deal conditions as those provided to a party receiving the more favorable rates. Upon Auxilium’s reasonable request, BTC shall provide written confirmation that it is in compliance with the requirements of this Section.

(B) Reduction In Cost of Goods. If BTC is successful in reducing the Cost of Goods, the Supply Price to Auxilium will be reduced by [**] percent ([**]%) of such dollar reduction.

provider, but in no event for direct distribution to patients. The number of Product samples to be provided to Auxilium shall be set forth in the Supply Agreement.

(D) Delay in Delivery. If, for any reason other than a force majeure, the BTC delivers any shipment of Product in accordance with this Article later than the date of delivery set out in the purchase order as agreed by the Parties pursuant to the Supply Agreement then:

(1) a 5% reduction in the Supply Price of Product if the shipment is delivered more than thirty (30) days but less than sixty (60) days late;

(2) a 10% reduction in the Supply Price of Product if the shipment is delivered more than sixty (60) days but less than ninety (90) days late; and

(3) a 15% reduction in the Supply Price of Product if the shipment is delivered more than ninety (90) days late.

(4) Once the price has been reduced in accordance with this Section, it will not revert to the original price unless and until the deliveries are no longer delayed.

(c) Additional Payment. In addition to the royalty payments to be made to BTC under Section 6.4(a), Auxilium shall pay to BTC an amount equal to a [**] percent ([**]%) mark-up of the Cost of Goods in respect of any sale by Auxilium or Partner of Product that is not Manufactured by or on behalf of BTC provided, however, that in the event BTC exercises the Supply Option and Auxilium thereafter exercises its Stand-By Rights pursuant to Section 6.4 (d) of this Agreement, the [**] percent ([**]%) mark-up payable hereunder shall not apply for so long as and to the extent BTC fails to supply ordered commercial quantities of the Product as provided in Section 6.4 hereof. For the sake of clarity, in the case where (i) Product is Manufactured by or on behalf of Auxilium and sold by Partner in Partner Territory, the aforementioned [**] percent ([**]%) mark-up shall be paid only once and shall be based on Auxilium’s Cost of Goods for sales in the Auxilium Territory, and (ii) where Product is Manufactured by Partner, the aforementioned [**] percent ([**]%) mark-up shall be paid only once and shall be based on Partner’s Cost of Goods for sales in the Partner Territory. The foregoing payment shall be due thirty (30) days following the sale by Auxilium in the Auxilium Territory or, in the case of a sale by Auxilium to the Partner, thirty (30) days following the receipt by Auxilium of the payment from the Partner. Together with each such payment, Auxilium will provide to BTC a report showing the basis for the calculation of the payment.

(d) Stand-By Rights; Back Up Supplier.

(i) Standby Rights. Auxilium will be entitled to seek from the Back-Up Supplier the greater of (a) 25% its requirements and (b) that quantity of Product that BTC is unable to provide, for a period of one (1) year following the occurrence of any of the events set forth in (A), (B) or (C) below (the “Standby Rights”). In the event that

** CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND WILL BE FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST.

Auxilium exercises its Standby Rights, the amount of Product that Auxilium is obligated to source from BTC pursuant to the Supply Agreement shall be reduced by such quantity for such one (1) year period.

(A) Failure to Meet Firm Order. If, for any reason, including, without limitation, as a result of a force majeure, BTC is unable to supply at least 75% of the amount of Product specified under a Firm Order, then Auxilium may exercise its Standby Rights by providing written notice; provided, however, that in the event that BTC is unable to supply the full amount specified in Auxilium’s Firm Order for two consecutive quarters (regardless of the amount of such material shortfall), Auxilium may exercise its Standby Rights by providing written notice to BTC. In addition, Auxilium shall be permitted to seek supply of any shortfall (regardless of amount of such shortfall or the number of times BTC has fulfill some or all of an Auxilium Firm Order) from the Back-Up Supplier on a per event basis without specifically invoking its Stand-By Rights.

(B) Egregious Delivery Delay. If, for any reason, other than a force majeure, BTC delivers any quantity of any Product more than ninety (90) days after the date such delivery was due, then Auxilium may exercise its Standby Rights by providing written notice.

(C) Nonconforming Product. If any three (3) consecutive shipments contain nonconforming Product and BTC (1) fails to replace any nonconforming Product with conforming Product in a timely manner or (2) fails to replace nonconforming Product within fifteen (15) Business Days after a dispute regarding whether any rejected quantity of any Product constitutes nonconforming Product is decided in Auxilium’s favor, then Auxilium may exercise its Standby Rights by providing written notice.

(ii) Offset. Auxilium will be entitled to offset any royalties owed to BTC by the amount represented by the difference between the Back Up Supplier’s supply price and BTC’s supply price.

(iii) BTC’s Use of the Back Up Supplier. If BTC opts to use the Back Up Supplier to provide Product to Auxilium, then BTC will either reimburse Auxilium for [**] of the documented costs and expenses Auxilium incurred in qualifying, sourcing and maintaining such Back Up Supplier or [**].

(iv) Inability to Manufacture.

BTC and Auxilium each shall immediately give notice to the other of any certification filed under the “U.S. Drug Price Competition and Patent Term Restoration Act of 1984” (or its foreign equivalent) claiming that a BTC Patent is invalid or that infringement will not arise from the manufacture, use or sale of any Product by a Third Party.

Notwithstanding the foregoing, (i) in the event of a material breach by Auxilium with respect to the Partner Territory, BTC shall simultaneously provide the aforementioned written notice to Partner pursuant to Section 11.3 hereof and, (ii) in the further event that Auxilium has not cured such breach in such ninety (90) day period, such Partner shall have the right to step-in and, within the ninety (90) day period, remedy or cure such breach for purposes of this Section 11.3. In the event that (x)

** CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND WILL BE FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST.

Partner is the entity remedying or curing such breach, (y) Partner is not at fault with respect to such material breach, and (z) Partner so requests of BTC in writing in connection with such remedy or cure, BTC shall promptly grant to Partner a license under the Licensed Technology and otherwise on the same economic and other terms as are contained in this Agreement covering the Partner Territory in substitution for Auxilium. For clarity, in the case of a material breach with respect to the Auxilium Territory, any termination of this Agreement shall related solely to the Auxilium Territory and this Agreement shall remain in full force and effect with respect to the Partner Territory. The Parties agree that the step-in rights granted to Partner under this Section 11.3 shall not serve as a precedent with respect to any future sublicense agreement.

11.4 Termination by Auxilium. Auxilium may terminate this Agreement in its entirety or on a country-by-country basis or on an Indication by Indication basis or on a Product by Product basis at any time upon ninety (90) days prior written notice to BTC.

11.5 Effect Of Termination.

(a) Effect On License. Upon the expiration or earlier termination of this Agreement, the rights licensed under this Agreement shall be treated as follows:

(i) Upon the expiration of the Term or the termination of this Agreement by Auxilium pursuant to Section 11.2 or Section 11.3, Auxilium shall have a fully paid-up, perpetual, irrevocable, royalty-free, transferable, worldwide, non-exclusive right and license under the Licensed Technology existing as of the date of such expiration to make, have made, use, offer to sell, and sell the Product in the Territory.

(ii) Upon termination of this Agreement by BTC pursuant to Section 11.2 or 11.3, or by Auxilium pursuant to Section 11.4 all rights to Product shall revert to BTC.

(b) Ongoing Obligations.

(i) Upon expiration or termination of this Agreement for any reason, each Party shall no later than thirty (30) days after such termination return to the other Party or destroy any Confidential Information disclosed by the other Party, except for one copy which may be retained in its confidential files.

(ii) Upon termination of this Agreement by BTC pursuant to Sections 11.2 or 11.3 or by Auxilium pursuant to Section 11.4, Auxilium shall assign and deliver to BTC all Regulatory Data and information (including registration dossiers) obtained for or in pursuing Regulatory Approvals, and all Regulatory Approvals (e.g., to BTC; designee in the Territory as permitted under the Law) for Product in the Territory received as of such termination date.

11.6 Inventory. Notwithstanding the foregoing, upon early termination of this Agreement pursuant to Section 11.2, 11.3 or 11.4, Auxilium shall have the right to sell all remaining Product in its inventory within six (6) months after the date of termination, but shall be bound to the royalty payments provided by Section 6.4 herein. Thereafter, Auxilium agrees to destroy any remaining supply of Product or return it to BTC at BTC’s request and direction.

12.2 BTC. BTC shall defend Auxilium and its Affiliates at BTC’s cost and expense, and will indemnify and hold Auxilium and its Affiliates and their respective directors, officers, employees, consultants, contractors, representatives, and agents harmless from and against any and all Losses incurred in connection with or arising out of any Third Party Claim directly relating to (i) material breach by BTC of any of its representations, warranties or obligations pursuant to this Agreement, (ii) gross negligence or willful misconduct of BTC in the exercise of any of its rights or the performance of any of its obligations under this Agreement, (iii) personal injury and other product liability resulting from BTC’s Development, Manufacture, or Commercialization of any Product, (iv) intellectual property infringement or related claims, including any Third Party Claim and trade secret misappropriation liability relating to the Development, Manufacture, or Commercialization of any Product, (v) any liability or other claims from the Manufacture, handling, packaging, storage, sale, or other disposition of any Product by BTC or any of its Affiliates or sublicensees, and (vi) any liability or claims arising from Product supplied by or on behalf of BTC to Auxilium that was not Manufactured in accordance with current Good Manufacturing Practices, Good Clinical Practice and Good Laboratory Practices, the specifications or all Laws and regulations except for such Losses that are indemnified pursuant to the Supply Agreement; provided that notwithstanding the foregoing, in all cases referred to in this Section 12.2, BTC shall have no liability to Auxilium for any Losses to the extent (and only to the extent) that such Losses were caused by any item for which Auxilium is required to indemnify BTC pursuant to Section 12.1.

** CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND WILL BE FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST.

(an “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any threatened or asserted claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided:

(a) That counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such Party’s expense (unless (i) the employment of counsel by such Indemnified Party has been authorized by the Indemnifying Party; or (ii) the Indemnified Party shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in the defense of such action, in each of which cases the Indemnifying Party shall pay the reasonable fees and expenses of one law firm serving as counsel for the Indemnified Party, which law firm shall be subject to approval, not to be unreasonably withheld, by the Indemnifying Party).

(b) The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement to the extent that the failure to give notice did not result in harm to the Indemnifying Party.

(c) No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the approval of each Indemnified Party which approval shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement which (i) would result in injunctive or other relief being imposed against the Indemnified Party; or (ii) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(d) Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

12.4 Escrow. In the event of any Third Party Claim against Auxilium for which BTC is obligated to indemnify Auxilium in accordance with Section 12.2, Auxilium shall be entitled, until a final un-appealable decision has been rendered or a settlement has been reached (a “Final Decision”), to pay an amount equal to fifty percent (50%) of all amounts due to BTC on Net Sales of Products (such aggregate amount, the “Escrowed Amount”) into an escrow account maintained by a Third Party reasonably acceptable to BTC. To the extent that Auxilium incurs any Losses in connection with such Third Party Claim, an amount equal to the amount of any such Losses shall be distributed to Auxilium out of such escrow account, with the remainder (if any) to be paid to BTC. In the event that the Escrow Amount is less than the amount of such Losses, BTC shall pay the difference to Auxilium within thirty (30) days of such Final Decision.

12.5 Insurance. During the Term, each of Auxilium and BTC shall maintain general liability and product liability insurance in the following amounts: (i) at all times prior to approval of a NDA for a Product, $3,000,000 per occurrence, and (ii) at all times after approval of a NDA for a Product, $5,000,000.

13.7 Waiver. The failure on the part of Auxilium or BTC to exercise or enforce any rights conferred upon it hereunder shall not be deemed to be a waiver of any such rights nor operate to bar the exercise or enforcement thereof at any time or times thereafter. The observance of any Term may be waived (either generally or in a particular instance and either retroactively or prospectively) by the Party entitled to enforce such term, but any such waiver shall be effective only if in writing signed by the Party against whom such waiver is to be asserted.

13.8 Force Majeure. Neither Party shall be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any Term, other than an obligation to make a payment, when such failure or delay is caused by or results from fire, floods, embargoes, government regulations, prohibitions or interventions, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts, acts of God, or any other cause beyond the reasonable control of the affected Party.

13.9 Severability. It is the intention of the Parties to comply with all Laws domestic or foreign in connection with the performance of its obligations hereunder. In the event that any provision of this Agreement, or any part hereof, is found invalid or unenforceable, the remainder of this Agreement will be binding on the Parties hereto, and will be construed as if the invalid or unenforceable provision or part thereof had been deleted, and the Agreement shall be deemed modified to the extent necessary to render the surviving provisions enforceable to the fullest extent permitted by law.

13.10 Government Acts.
