The Parties shall negotiate the Co-Promotion Agreement in good faith and with sufficient diligence as is required to execute and deliver the Co-Promotion Agreement within [***] days after ARCHEMIX provides its written indication of interest pursuant to the first sentence of this paragraph.

(b) Failure to Agree. To the extent that MERCK enters into and conducts negotiations with respect to the Co-Promotion Agreement for a Product in good faith and the Parties fail to execute and deliver the Co-Promotion Agreement within [***] day period described in Section 4.9.2(a) above, then (i) MERCK shall continue to have the exclusive right and responsibility during the Term to Commercialize such Product in the Territory (including the United States of America and its territories and possessions) for use in the Field and (ii) the fact

that the Parties were unable to agree on a Co-Promotion Agreement shall not entitle ARCHEMIX to claim damages or any other sort of compensation whatsoever.

4.10 Product Recalls. In the event that any Regulatory Authority issues or requests a recall or takes similar action in connection with a Product, or in the event a Party reasonably believes that an event, incident or circumstance has occurred that may result in the need for a recall, market withdrawal or other corrective action regarding a Product, such Party shall promptly advise the other Party thereof by telephone or facsimile. Following such notification, MERCK shall decide and have control of whether to conduct a recall or market withdrawal (except in the event of a recall or market withdrawal mandated by a Regulatory Authority, in which case it shall be required) or to take other corrective action in any country and the manner in which any such recall, market withdrawal or corrective action shall be conducted; provided, that, MERCK shall keep ARCHEMIX regularly informed regarding any such recall, market withdrawal or corrective action. MERCK shall bear all expenses of any such recall, market withdrawal or corrective action (including, without limitation, expenses for notification, destruction and return of the affected Product and any refund to customers of amounts paid for such Product).

5. PAYMENTS

5.1 Technology Access and License Fee. MERCK shall pay ARCHEMIX a non-refundable technology access and license fee in the amount of Three Million Dollars (US $3,000,000) by wire transfer within thirty (30) days of the Effective Date, according to instructions that ARCHEMIX shall provide.

5.2 License Maintenance Fee. MERCK shall pay ARCHEMIX a non-refundable license maintenance fee in the amount of [***] Dollars (US $[***]) by wire transfer within [***] days of (i) the Effective Date and (ii) on each of the [***] of the Effective Date during the Research Program Term, according to instructions that ARCHEMIX shall provide.

5.3 R&D Funding.

5.3.1 Payment of R&D Funding. In consideration of the performance by ARCHEMIX of its activities under the Annual Research Plan(s) as described in Section 3.2, during the Research Program Term MERCK will pay ARCHEMIX the applicable Quarterly FTE Payment on or prior to the first day of each Calendar Quarter; provided, that, an invoice corresponding with such Calendar Quarter has been received by MERCK. Notwithstanding the above, in view of the activities to be performed by ARCHEMIX during the initial Calendar Quarter, MERCK will pay ARCHEMIX [***] Dollars (US $[***]) on the Effective Date; provided, that, an invoice corresponding with the initial Calendar Quarter has been received by MERCK. ARCHEMIX shall provide a report to the JPT within [***] days of the end of each Calendar Quarter during the Research Program Term that specifies the actual number of FTEs expended during the period covered therein. Within [***] days of the end of each Calendar Year during the Research Program Term, ARCHEMIX shall provide MERCK with an annual reconciliation statement (“Annual Reconciliation Statement”) that specifies the actual number of FTEs expended during the previous [***] Calendar Quarters in the aggregate. MERCK shall

reimburse ARCHEMIX in full for any FTEs expended by ARCHEMIX in excess of the cumulative FTE Costs owed by MERCK for such Calendar Year (the “MERCK Contribution”) as indicated by any Annual Reconciliation Statement if such excess was approved by the JSC. To the extent that any Annual Reconciliation Statement indicates that ARCHEMIX expended FTEs in excess of the MERCK Contribution and such excess was not approved by the JSC then, (a) MERCK shall reimburse ARCHEMIX for all amounts in excess of the MERCK Contribution, not to exceed [***] percent ([***]%) of the MERCK Contribution and (b) all FTE Costs in excess of [***] percent ([***]%) of the MERCK Contribution shall be borne by ARCHEMIX.

5.3.2 R&D Funding Audit Rights. ARCHEMIX shall keep complete and accurate books and financial records pertaining to the number of FTEs utilized in conducting the Research Program and the ARCHEMIX Development Activities, if any, which books and financial records shall be kept in accordance with GAAP and shall be retained by ARCHEMIX until [***] years after the end of the Contract Year to which they pertain. Upon [***] days written notice, MERCK shall have the right to appoint at its expense an independent certified public accountant reasonably acceptable to ARCHEMIX to audit the books and financial records of ARCHEMIX relating to the number of FTEs utilized in conducting the Research Program and the ARCHEMIX Development Activities during any Contract Year; provided, that, MERCK shall not have the right to audit any Contract Year more than once or more than [***] years after the end of such Contract Year or to conduct more than one such audit in any [***] period. All books and financial records made available for audit shall be deemed to be Confidential Information of ARCHEMIX. The results of each audit, if any, shall be reported in writing to both Parties promptly (but in no event later than [***] days) after the audit and shall be binding on both Parties. In the event that there was an error relating to the reported FTEs utilized in conducting the Research Program and/or the ARCHEMIX Development Activities during such Contract Year, (a) if the effect of the error resulted in an overpayment by MERCK, ARCHEMIX shall promptly (but in any event no later than [***] days) after ARCHEMIX’ receipt of the report so concluding, make payment to MERCK of the overpayment and (b) if the effect of the error resulted in an underpayment by MERCK, then MERCK shall promptly (but in no event later than [***] days after MERCK’s receipt of the report so concluding) make payment to ARCHEMIX of the underpayment amount. MERCK shall bear the full cost of such audit unless such audit discloses an over reporting by ARCHEMIX of more than [***] percent ([***]%) of the aggregate amount of FTE Costs reportable in any Calendar Year, in which case ARCHEMIX shall reimburse MERCK for all reasonable costs incurred by MERCK in connection with such audit.

5.3.3 R&D External Costs. In addition to the funding obligations in Section 5.3.1 above, and without limiting the generality of the provisions of Section 4.2 hereof, MERCK shall [***] for the payment of [***] Third Party research and Development activity costs (“Third Party Costs”), including, without limitation, contract research organizations, contract personnel and consultant costs, incurred by ARCHEMIX to the extent set forth in an Annual Research Plan or Annual Development Plan or otherwise agreed to in writing by MERCK.

5.4 Milestone Payments.

5.4.1 Milestones. Within [***] days after the occurrence of the following milestone events, MERCK shall make the corresponding non-refundable, non-creditable (except as provided in Section 5.4.2) payments to ARCHEMIX for each Program Target, regardless of the number of Products that are Developed and Commercialized under this Agreement against such Program Target:


Milestone Event		Milestone Payment
1. [***]		$[***]
2. [***]		$[***]
3. [***]		$[***]
4. [***]		$[***]
5. [***]		$[***]
6. [***]		$[***]

14. [***]		$[***]

For purposes of clarity (a) milestone 1 shall be paid for the first [***] Project Targets to yield an Optimized Lead Compounds; (b) [***] shall be paid for a given Product for up to [***] different Indications; and (c) if payment is made for any of [***] with respect to any Product and any of the preceding milestone payments have not been made with respect to such Product, then such earlier milestone payments shall be made concurrently therewith (for example, if milestone 5 [***] is paid, but milestone 4[***] has not been paid, then milestone payments 5 and 4 shall [***] on the basis of [***]). Notwithstanding anything contained herein to the contrary, in no event will MERCK be liable for milestone payments accrued for achievement of any of milestones 1-14 in excess of milestone payments made by MERCK of [***] Dollars ($[***]) in the aggregate for each Program Target.

5.4.2 Determination that Milestone Events have Occurred; Invoice for Milestone Payments. MERCK shall provide ARCHEMIX with written notice within [***] days of each occurrence of a milestone event set forth in Section 5.4.1. ARCHEMIX shall provide MERCK with an invoice for the amount of the milestone payment that is due and payable as promptly as possible after receipt of such notice. In the event that, notwithstanding the fact that MERCK has not given such a notice, ARCHEMIX believes any such milestone event has occurred, it shall so notify MERCK in writing and shall provide to MERCK data, documentation or other information that supports its belief. Any dispute under this Section 5.4.2 that relates to whether or not a milestone event has occurred shall be referred to the JSC to be resolved in accordance with Section 2.1.6.

5.5 Payment of Royalties; Royalty Rates; Accounting and Records.

5.5.1 Payment of Royalties.

(a) Royalty Rates. MERCK shall pay ARCHEMIX a royalty based on Annual Net Sales of each Product in each Calendar Year (or partial Calendar Year) commencing with the First Commercial Sale of such Product in any country in the Territory and ending upon the last day of the last Royalty Term for such Product, at the following rates:


Annual Net Sales		Royalty Rate (%)
[***]		[***]%
[***]		[***]%
[***]		[***]%
[***]		[***]%

The following hypothetical example illustrates the calculation of royalties under Section 5.5.1(a): If, in any Calendar Year during the Term, Annual Net Sales of a Product are $[***], the applicable royalty would be $[***], [***]% of Net Sales for Net Sales up to $[***], [***]% of Net Sales for Net Sales over $[***] and up to $[***] and [***]% of Net Sales for Net Sales over $[***].

(b) Royalty Offsets. In the event that MERCK, in order to practice the license granted to it under Section 7.2 of this Agreement in any country in the Territory, is required to and actually makes royalty, milestone or license fee payments to any Third Party (“Third Party Payments”) in order (A) to obtain a license to an issued patent or patents in the absence of which the Lead Compound portion of the Product could not legally be manufactured, imported, sold, exported, or otherwise exploited in such country and/or (B) to obtain a license to an issued patent or patents, in the absence of which the Licensed Patent Rights cannot legally be practiced in such country for making, using, importing, offering for sale, selling, exporting or otherwise exploiting such Product, then the royalties payable to ARCHEMIX for such Product under Section 5.5.1(a) with respect to such country may be reduced by [***] percent ([***]%) of the amount of such Third Party Payments. Notwithstanding the foregoing, (i) such reductions

shall in no event reduce the royalty that would otherwise be payable for such Product under Section 5.5.1 with respect to such country by more than [***] percent ([***]%) of the amount otherwise payable with respect to Net Sales of such Product in such country, (ii) MERCK shall be responsible for the payment of any royalty, milestone or license fee payments to any Third Party relating to methods or processes for making or manufacturing the Product and the royalties payable to ARCHEMIX pursuant to Section 5.5.1(a) [***], and (iii) in the event that MERCK requires that ARCHEMIX use in the Research Program molecules, methods and/or processes not identified in Schedule 11 or MERCK requires that ARCHEMIX use in the Research Program specific molecules, methods and/or processes where such molecules, methods and/or processes are generically identified in Schedule 11 (“Requested Chemistry”), thereby giving rise to the obligation to pay royalty, milestone or license fee payments to a Third Party (“Third Party Chemistry Payments”), MERCK [***] of such Third Party Chemistry Payments and the royalties payable to ARCHEMIX pursuant to Section 5.5.1(a) [***] Third Party Chemistry Payments.

(c) Competing Aptamer Products. In the event that a Third Party sells a Competing Aptamer Product (as defined below) in a country in which a Product is then being sold and such Competing Aptamer Product is not covered by a Valid Claim under the Licensed Patent Rights, Program Aptamer-Specific Patent Rights, or Joint Patent Rights in such country, then, during the period in which sales of the Competing Aptamer Product by such Third Party are equal to at least [***] percent ([***]%) of MERCK’s volume-based market share of the Product in such country (as measured by prescriptions or other similar information available in such country) all applicable royalties in effect with respect to such Product in such country as specified in Section 5.5.1(a) shall be [***] by [***] percent ([***]%). Notwithstanding the foregoing, (i) MERCK’s obligation to pay royalties at the full royalty rates shall be reinstated on the first day of the Calendar Quarter immediately following the Calendar Quarter in which sales of such Competing Aptamer Product account for less than [***] percent ([***]%) of MERCK’s volume-based market share in such country and (ii) the provisions of this Section 5.5.1(c) shall not apply for any country in which MERCK has not [***] for [***] for the applicable Collaboration Aptamer(s) or has not otherwise used commercially reasonable efforts to [***] for such Collaboration Aptamer(s). For purposes of this Section 5.5.1(c), a “Competing Aptamer Product” means a pharmaceutical product that (i) contains an [***] and (ii) is marketed in such country for the same [***] as the [***].

(d) Generic Products. In the event that a Third Party sells a Generic Product (as defined below) in a country in which a Product is then being sold and such Generic Product is not covered by a Valid Claim under the Licensed Patent Rights, Program Aptamer-Specific Patent Rights, or Joint Patent Rights in such country, then during the period in which sales of the Generic Product by such Third Party are equal to: (i) at least [***] percent ([***]%) of MERCK’s volume-based market share of the Product in such country (as measured by prescriptions or other similar information available in such country), MERCK shall pay [***] percent ([***]%) of the full applicable royalties in effect with respect to such Product in such country as specified in Section 5.5.1(a). Notwithstanding the foregoing, (i) MERCK’s obligation to pay royalties at the full royalty rates shall be reinstated on the first day of the Calendar Quarter immediately following the Calendar Quarter in which sales of such Generic Product account for less than [***] percent ([***]%), (ii) the provisions of this Section 5.5.1(d) shall not apply for any country in which MERCK has not [***] for [***] for the applicable Collaboration

Aptamer(s) or has not otherwise used commercially reasonable efforts to [***] for such Collaboration Aptamer(s). For purposes of this Section 5.5.1(d), a “Generic Product” means a pharmaceutical product that contains the [***] and [***] to such [***].

(e) Maximum Adjustment of Royalty Rate. Notwithstanding anything to the contrary in this Agreement, under no circumstances shall the royalty rates in Section 5.5.1(a) be cumulatively reduced below [***] percent ([***]%) of the rates set forth therein.

(f) Know-How Payments. The Parties hereby acknowledge and agree that any royalties that are payable for a Product for which no Patent Rights exist shall be in consideration of (i) ARCHEMIX’s expertise and know-how concerning the identification of Aptamers in the Field, including its development of the SELEX^® Process and its other Aptamer-related development activities conducted prior to the Effective Date; (ii) the performance by ARCHEMIX of the Research Program, (iii) the disclosure by ARCHEMIX to MERCK of results obtained in the Research Program; (iv) the licenses granted to MERCK hereunder with respect to Licensed Technology and Joint Technology that are not within the claims of any Patent Rights Controlled by ARCHEMIX; (v) the restrictions on ARCHEMIX in Section 7.6.1; and (vi) the “head start” afforded to MERCK by each of the foregoing.

(g) Payment Dates and Reports. Royalty payments shall be made by MERCK within [***] days after the end of each [***] commencing with the [***] in which the First Commercial Sale of a Product occurs. MERCK shall also provide, at the same time each such payment is made, a report showing: (a) the Net Sales of each Product by type of Product and country in the Territory; (b) the basis for any deductions from gross amounts billed or invoiced to determine Net Sales; (c) the applicable royalty rates for such Product; (d) the exchange rates used in calculating any of the foregoing; and (e) a calculation of the amount of royalty due to ARCHEMIX.

(h) Combination Products. The earned royalty due on a Combination Product shall be determined pro rata on a Combination Product-by-Combination Product and country-by-country basis, by multiplying Net Sales of the Combination Product by the fraction A/(A+B), where A is the invoice price of the Product when sold separately and B is the invoice price of the Supplemental Product when sold separately by a Party, its Affiliate or its Sublicensee or, if not sold by them, then the average invoice price when sold separately by Third Parties. If the Supplemental Product in the Combination Product is not sold separately by any Person, Net Sales shall be calculated by multiplying actual net revenues derived from sales of the Combination Product by the fraction A/C, where A is as previously defined and C is the invoice price of the Combination Product sold by a Party, its Affiliate or its Sublicensee. For purposes of clarity, the average invoice price and the actual net revenues for any Supplemental Product shall be for a quantity comparable to that contained in the Combination Product and shall be of the same class, purity and potency as that contained in the Combination Product. If neither the Product nor the Supplemental Product included in the Combination Product are sold separately, Net Sales shall be calculated based on the mutual written agreement of the Parties as to a reasonable allocation between the Product and the Supplemental Product, taking into account total manufacturing costs, proprietary protection and relative contribution thereof. If the Parties

are unable to reach agreement on an appropriate method of determining royalties for a Combination Product, the matter shall be submitted to the JSC for resolution under Section 2.1.6.

5.5.2 Records; Audit Rights. MERCK and its Affiliates and Sublicensees shall keep and maintain for [***] years from the date of each payment of royalties hereunder complete and accurate records of gross sales and Net Sales by MERCK and its Affiliates and Sublicensees of each Product, in sufficient detail to allow royalties to be determined accurately. ARCHEMIX shall have the right for a period of [***] years after receiving any such royalty payment to appoint at its expense an independent certified public accountant reasonably acceptable to MERCK to audit the relevant records of MERCK and its Affiliates and Sublicensees to verify that the amount of such payment was correctly determined. MERCK and its Affiliates and Sublicensees shall each 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 [***] days written notice from ARCHEMIX, solely to verify that royalty payments hereunder were correctly determined. Such audit right shall not be exercised by ARCHEMIX more than [***] in any [***] or more than [***] with respect to sales of a particular Product in a [***]. All records made available for audit shall be deemed to be Confidential Information of MERCK. The results of each audit, if any, shall be binding on both Parties. In the event there was an underpayment by MERCK hereunder, MERCK shall promptly (but in any event no later than [***] days after MERCK’s receipt of the report so concluding) make payment to ARCHEMIX of any shortfall. ARCHEMIX shall bear the full cost of such audit unless such audit discloses an underreporting by MERCK of more than [***] percent ([***]%) of the aggregate amount of royalties payable in any Calendar Year, in which case MERCK shall reimburse ARCHEMIX for all costs incurred by ARCHEMIX in connection with such audit.

5.5.3 Overdue Royalties and Milestones. All royalty payments not made within the time period set forth in Section 5.5.1(g), including underpayments discovered during an audit, and all milestone payments not made within the time period specified in Section 5.4.1, shall bear interest at a rate of [***] percent ([***]%) per month from the due date until paid in full or, if less, the maximum interest rate permitted by Applicable Laws. Any such overdue royalty or milestone payment shall, when made, be accompanied by, and credited first to, all interest so accrued.

5.5.4 Payments. All payments made by MERCK hereunder shall be made by wire transfer in US Dollars in accordance with instructions given in writing from time to time by ARCHEMIX and shall be free and clear of any taxes, duties, levies, fees or charges including any withholding taxes. If by law, regulations or fiscal policy of a particular country in the Territory, remittance of royalties in United States Dollars is restricted or forbidden, written notice thereof shall promptly be given to ARCHEMIX, and such payment shall be made by the deposit thereof in local currency to the credit of ARCHEMIX in a recognized banking institution designated by ARCHEMIX by written notice to MERCK. When in any country in the Territory the law or regulations prohibit both the transmittal and the deposit of royalties, on sales in such country, such payments shall be suspended for as long a such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that MERCK would have been under an

obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted, to the extent allowable.

5.5.5 Taxes. Any income taxes or other taxes which MERCK is required by law to pay or withhold on behalf of ARCHEMIX with respect to milestones, royalties and any other monies or other transfer for value payable or provided to ARCHEMIX under this Agreement shall be deducted from such milestones, royalties and any other monies due to ARCHEMIX under this Agreement. MERCK shall provide ARCHEMIX with documentation of such withholding in a manner that is satisfactory for purposes of reporting to the U.S. Internal Revenue Service. Payments made by either Party for goods and services provided by the other Party under this Agreement are exclusive of Value Added Tax, sales tax or any other similar or substitute tax which will be additionally payable by the Party receiving the goods or services in the event that Value Added Tax, sales tax or any other similar or substitute tax applies to any of these payments; provided, that, the Party providing the goods or services will issue to the other Party an appropriate invoice to support any such charge. MERCK shall submit to ARCHEMIX reasonable proof of payment of the withholding taxes contemplated by this Section, together with an accounting of the calculations of such taxes, within [***] days after which such withholding taxes are remitted to the proper authority. The Parties will cooperate reasonably in completing and filing documents required under the provisions of any applicable tax laws or under any other Applicable Law, in connection with the making of any required tax payment or withholding payment, or in connection with any claim to a refund of or credit for any such payment. The Parties will cooperate to minimize such taxes in accordance with Applicable Law.

5.5.6 Foreign Currency Exchange. All royalties shall be payable in full in the United States in United States Dollars, regardless of the countries in which sales are made. With respect to amounts invoiced by MERCK (or its Affiliates or Sublicensees) for Products, all such amounts shall be expressed in EURO and, if applicable, the currency in which the amount was invoiced. Any conversion from a currency to EURO shall be calculated using MERCK’s standard exchange rate methodology applied in its external reporting in effect as of the Effective Date and set forth on Schedule 10 attached hereto. Such Net Sales shall be converted into United States Dollars as follows:

(A/B), where

A = “Net Sales” (as defined above) in such Calendar Quarter expressed in EURO; and

B = foreign exchange conversion rate, expressed in EURO per United States Dollar (using, the applicable EURO exchange rate, set forth on Schedule 10 attached hereto or any other mutually agreed upon source, for such Calendar Quarter).

13.1.1 Full Arbitration. Any dispute, controversy or claim arising between the Parties with respect to this Agreement, including any dispute, controversy or claim relating to any Excepted Decision (each, a “Dispute”), shall be resolved by binding arbitration before a panel of three (3) arbitrators in accordance with the rules of the ICC in effect at the time the proceeding is initiated; provided, that, any Dispute as to an Excepted Decision shall be resolved pursuant to Section 13.1.2. In any such arbitration, the following procedures shall apply:

(a) The panel will be comprised of one arbitrator chosen by MERCK, one by ARCHEMIX and the third by the two so chosen. If either, or both, of MERCK or

ARCHEMIX fails to choose an arbitrator or arbitrators within thirty (30) days after receiving notice of commencement of arbitration or if the two arbitrators fail to choose a third arbitrator within thirty (30) days after their appointment, then either or both Parties shall immediately request that the ICC select the remaining number of arbitrators to be selected, which arbitrator(s) shall have the requisite scientific background, experience and expertise. The place of arbitration shall be New York, New York.

(b) Either Party may apply to the arbitrators for interim injunctive relief until the arbitration decision is rendered or the Dispute is otherwise resolved.

The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees in connection with any such arbitration; provided, that, the non-prevailing Party shall pay the costs and expenses incurred by the prevailing Party in connection with any such arbitration, including reasonable attorneys’ fees and costs. The Parties acknowledge that while Section 13.4 shall apply to any such Dispute, it is the intention of the Parties not to use the discovery rules of the State of New York in connection with any such Dispute.

(c) Except to the extent necessary to confirm an award or decision or as may be required by Applicable Laws, neither Party nor any arbitrator may disclose the existence or results of any arbitration without the prior written consent of both Parties. In no event shall any arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the Dispute would be barred by the applicable New York statute of limitations.

(d) In the event of a Dispute involving the alleged breach of this Agreement (including, without limitation, whether a Party has satisfied its diligence obligations hereunder), (i) neither Party may terminate this Agreement under Section 10.2.2 until resolution of the Dispute pursuant to this Section 13.1.1 and (ii) if the arbitrators render a decision that a breach of this Agreement has occurred, the arbitrators shall have no authority to modify the right of the non-breaching Party to terminate this Agreement in accordance with Section 10.2.2.

(e) Any disputed performance or suspended performance pending the resolution of a Dispute that the arbitrators determine to be required to be performed by a Party shall be completed within a reasonable time period following the final decision of the arbitrators.

(f) The decision of the arbitrators shall be the sole, exclusive and binding remedy between the Parties regarding the determination of all Disputes presented. Any monetary payment to be made by a Party pursuant to a decision of the arbitrators shall be made in United States dollars, free of any tax or other deduction.

13.1.2 Accelerated Arbitration. To the extent a Dispute submitted to arbitration by a Party under Section 13.1.1 is claimed, by either Party, to involve an Excepted Decision, the following procedures shall apply:

(a) The Parties shall mutually select a single independent, conflict-free arbitrator (the “Expert”), who shall have sufficient scientific background and experience to resolve the Dispute. If the Parties are unable to reach agreement on the selection of an Expert within fifteen (15) business days after submission to arbitration, then either or both Parties shall immediately request that the ICC select an arbitrator with the requisite scientific background, experience and expertise. The place of arbitration shall be New York, New York.

(b) Each Party shall prepare and submit a written summary of such Party’s position and any relevant evidence in support thereof to the Expert within thirty (30) days of the selection of the Expert. Upon receipt of such summaries from each Party, the Expert shall provide copies of the same to the other Party. Within thirty (30) days of the delivery of such summaries by the Expert, each Party shall submit a written rebuttal of the other Party’s summary and may also amend and re-submit its original summary. Oral presentations shall not be permitted unless otherwise requested by the Expert. The Expert shall make a final decision with respect to the Dispute within thirty (30) days following receipt of the last of such rebuttal statements submitted by the Parties. Each Party shall bear its own costs and expenses and attorneys’ fees, and the Party that does not prevail in the arbitration proceeding shall pay the Expert’s fees and any administrative fees of arbitration.

Merck KGaA and Archemix to Collaborate on Aptamer-Based Cancer Therapeutics

Darmstadt, January xx, 2007 – Merck KGaA announced today that it has signed a multi-year, multi-target agreement with Archemix Corp. of Cambridge, Massachusetts, that focuses on the discovery, development, and commercialization of first-in-class aptamer-based therapeutics to treat cancer.

Under terms of the agreement, Archemix will receive an upfront payment and committed research funding of as much as $10 million. Archemix also could receive milestones and royalty payments for products successfully commercialized under the collaboration. In addition, Archemix may participate in the co-promotion of products that result from the collaboration. Other financial terms were not disclosed.

“Archemix is the leader in the field of aptamers, a new class of drugs that has tremendous potential in the battle against cancer,” said Xx. Xxxxxxxx Xxxxxxxxxx, Executive Senior Vice President and Director of Research for Merck Serono. “We hope this collaboration will further our efforts to provide physicians and oncology patients with innovative, targeted cancer treatments.”

Xx. Xxxxx Xx Xxxxx, President and Chief Executive Officer of Archemix, commented: “Merck is a recognized global leader in oncology drug development and marketing and we are excited to be working with them to apply our scientific expertise in developing novel aptamer therapeutics for cancer. This alliance is the fourth major partnership we have formed over the past 6 months and is consistent with our strategy to enable partners to leverage aptamers as drugs on a target by target basis.”

About Aptamers

Aptamers are single-stranded nucleic acids that form well-defined three-dimensional shapes, allowing them to bind target molecules in a manner that is conceptually similar to antibodies. Aptamers combine the optimal characteristics of small molecules and antibodies, including high specificity and affinity, chemical stability, low immunogenicity and the ability to target protein-protein interactions. In contrast to monoclonal antibodies, aptamers are chemically synthesized rather than biologically expressed, offering a significant cost advantage.

About Archemix Corp.

Archemix Corp. is a privately-held biopharmaceutical company based in Cambridge, Massachusetts. The company’s mission is to develop aptamers as a class of directed therapeutics for the prevention and treatment of human disease. Because of their unique properties and proven efficacy, aptamers offer an alternative to biologics and small molecules in numerous applications and offer the potential to be a major class of drugs for the treatment of unmet medical needs.

Archemix’s aptamer expertise is complemented by a robust patent estate comprised of over 220 issued and 230 pending patents covering the identification, composition, and use of therapeutic aptamers. In addition to the company’s core aptamer generation technology, Archemix possesses strong expertise in both pre-clinical and clinical drug development. Further information on Archemix can be found at xxx.xxxxxxxx.xxx.
