Subject to the terms of this Agreement, Seller shall use its Commercially Reasonable Efforts to manufacture and supply to Purchaser its requirements of the Product for sale and distribution to Purchaser Customers in the Territory in accordance with Purchaser’s Purchase Orders as provided herein. Seller shall not, and shall cause its Affiliates not to, manufacture or supply the Product to Purchaser Customers in the Territory. Notwithstanding anything herein to the contrary, the parties acknowledge and agree that Seller retains all rights to develop, manufacture, supply, sell, distribute, market, promote and otherwise commercialize, directly or through Seller’s Affiliates or third parties, Product to customers other than Purchaser Customers in the Territory; and without limiting the foregoing and by way of clarification, Seller’s retained rights shall expressly include the right to sell Product to drug wholesalers or any other Persons so long as Seller shall not supply, sell or distribute Product to drug wholesalers or any other Person for resale to any customer included in items (a)-(e) of Section 1.46.

2.1.2 Seller hereby represents that it has filed with the FDA ANDA, File No. 76-684, for the Product. Seller shall, at its expense, use Commercially Reasonable Efforts to prosecute the ANDA and to obtain approval from the FDA of the ANDA. Seller shall promptly upon its receipt of same deliver to Purchaser written notice certifying that Seller has received final FDA approval of the Product’s ANDA. The ANDA and all other regulatory approvals related to the manufacture and supply of the Product shall be in Seller’s name and owned exclusively by Seller. In addition, Seller shall, at its expense, use Commercially Reasonable Efforts to obtain a Favorable Resolution to enable FDA approval of the Product’s ANDA and the launch of the Product in the Territory. Notwithstanding the foregoing, nothing herein shall constitute a guarantee or warranty from Seller that the ANDA for the Product will be approved by the FDA, or, if the Product ANDA is approved, any market exclusivity will be awarded, or any other regulatory approvals will be obtained by Seller or that a Favorable Resolution will be obtained. Nothing herein shall limit Purchaser’s right to terminate this Agreement pursuant to its terms.

2.2 Agreement to Purchase.

2.2.1 Subject to the terms of this Agreement, Purchaser shall purchase exclusively from Seller all of Purchaser’s requirements for the Product for marketing, sale and distribution to Purchaser Customers in the Territory. Purchaser shall use Commercially Reasonable Efforts to market, sell and distribute the Product throughout the Territory to Purchaser Customers. Subject to the foregoing, Purchaser does not make any guaranty or warranty as to any minimum level of Gross Profits or Net Sales. Nothing herein shall limit each party’s right to terminate this Agreement pursuant to its terms, including Section 8.4. Unless otherwise consented to in writing by Seller, Purchaser shall not offer the Product as a loss leader, whether alone or in connection with any other product or sell the Product in combination or otherwise bundle the Product with other products in any fashion which decreases the revenue that would otherwise be attributable to the Product had it not been sold as a loss leader or in combination or otherwise bundled. Subject to the foregoing and Purchaser performing its obligations hereunder (including its obligation to use Commercially Reasonably Efforts to sell and distribute the Product), launch timing, pricing, marketing, sale and distribution and related strategy for the Product for sale and distribution to Purchaser Customers in the Territory shall be the sole responsibility of, and shall be solely controlled by, Purchaser.

2.2.2 Purchaser shall, and shall cause its Affiliates to, sell and distribute the Product only to Purchaser Customers in the Territory and only in accordance with Applicable Law and the Product’s ANDA. Purchaser shall reasonably cooperate with Seller in investigating and tracing any sales of the Product outside of the Territory or to any Persons in the Territory other than Purchaser Customers originating from sales by Purchaser hereunder. Seller shall not, and shall cause its Affiliates not to, sell and distribute the Product to Purchaser Customers in the Territory (provided that, by way of clarification, Seller may sell Product to drug wholesalers or any other Persons so long as Seller shall not supply, sell or distribute Product to drug wholesalers or any other Persons for resale to any customer included in items (a)-(e) of Section 1.46). Seller shall reasonably cooperate with Purchaser in investigating and tracing any sales of the Product to any Purchaser Customers originating from sales by Seller hereunder.

2.2.3 During the term of this Agreement and, if this Agreement is terminated by Purchaser pursuant to Section 8.4, for a period of 12 months after such termination, neither Purchaser nor its Affiliates shall sell or distribute in the Territory any product that is or purports to be a generic equivalent (i.e. bioquivalent and legally substitutable) of the Lovenox® brand product, other than the Product supplied by Seller hereunder. [***].

2.3 Commercial Launch of the Product.

2.3.1 Notice of Launch. At any time after Seller receives both (i) a Favorable Resolution (which may, but is not required to be, a Final Favorable Resolution) and (ii) FDA approval of the Product’s ANDA and confirmation from the FDA that Seller has been awarded 180 days of “first to file” market exclusivity in accordance with Section 505(j)(5)(B)(iv) of the Act, Seller shall be entitled to deliver to Purchaser a written notice setting forth Seller’s intention to commence the commercial sale of the Product in the Territory. Such written notice shall be referred to herein as an “At-Risk Launch Notice,” unless based on a Final Favorable Resolution, in which case such written notice shall be referred to herein as a “Non-At-Risk Launch Notice.” As used herein, a “Launch Notice” may refer generally to an At-Risk Launch Notice and/or a Non-At-Risk Launch Notice. Notwithstanding the foregoing, in the event that Seller receives FDA approval of the Product’s ANDA, but Seller is not awarded 180 days “first to file” market exclusivity and/or has not received a Favorable Resolution, Seller, at its option, may notify Purchaser of Seller’s desire to commence the commercial sale of the Product in the Territory. In such event, Seller and Purchaser shall negotiate in good faith the terms and conditions of any Product launch to Purchaser Customers in the Territory; provided that, by way of clarification, nothing herein shall prevent (i) Seller from selling and distributing such Product in the Territory so long as Seller does not sell or distribute such Product to Purchaser Customers (provided that, by way of clarification, Seller may sell Product to drug wholesalers or any other Persons so long as Seller shall not supply, sell or distribute Product to drug wholesalers or any other Persons for resale to any customer included in items (a)-(e) of Section 1.46) or (ii) Purchaser from terminating this Agreement pursuant to its terms.

2.3.2 At-Risk Launch. In the event that Purchaser receives an At-Risk Launch Notice, Purchaser shall notify Seller in writing within 10 days of Purchaser’s receipt thereof whether or not Purchaser agrees to launch the commercial sale of the Product to Purchaser Customers in the Territory as contemplated herein based on such At-Risk Launch Notice (an “At-Risk Launch”). In the event that Purchaser notifies Seller that it has determined to engage in an At-Risk Launch, Purchaser shall proceed according to the provisions of Section 2.3.3 below. In the event that Purchaser notifies Seller that it has determined to not engage in an At-Risk Launch, Seller shall have 10 days from receipt of Purchaser’s notice to notify Purchaser in writing whether or not Seller has determined to engage in an At-Risk Launch without Purchaser acting as Seller’s distributor of the Product to the Purchaser Customers in the Territory (a “Seller Launch”). In the event that Seller notifies Purchaser that it has determined to so engage in a Seller Launch, subject to Sections 2.3.4 and 2.3.5 below, this Agreement (including any rights of Purchaser to sell and distribute the Product in the Territory) shall automatically and immediately terminate as of the date of such Seller’s notice to Purchaser. In the event that Seller notifies Purchaser that it has determined to not engage in a Seller Launch, this Agreement shall continue in full force and effect and Seller may at any time thereafter submit a new Launch Notice, at which time the parties shall, among other things, again proceed in accordance with the provisions of this Section 2.3.

2.3.3 Obligation to Launch. In the event that Seller delivers to Purchaser a Non-At-Risk Launch Notice or Purchaser notifies Seller that Purchaser has determined to engage in an At-Risk Launch, Purchaser shall (i) pay the milestone payment set forth in Section 3.1(b) below in accordance with the provisions thereof, and (ii) subject to the terms of this Agreement, Purchaser shall use Commercially Reasonable Efforts to commence with Purchaser’s First Commercial Sale as soon as commercially practicable thereafter, but in no event later than 5 business days following Purchaser’s receipt of Launch Quantities.

2.3.4 Payment of Compensatory Payments upon a Seller Launch. Subject to Section 2.3.5 below, in the event that Seller engages in a Seller Launch, Seller shall pay to Purchaser payments (the “Compensatory Payments”), up to the aggregate amount of [***] (the “Maximum Compensatory Payments”), equal to:

(a) during the first six full calendar months following Seller’s First Commercial Sale pursuant to the Seller Launch, the greater of (i) [***] of Seller’s Net Sales of Product sold in the Territory and (ii) [***];

(b) during the second six full calendar months following Seller’s First Commercial Sale pursuant to the Seller Launch, the greater of (i) [***] of Seller’s Net Sales for Product sold in the Territory and (ii) [***]; and

(c) [***] of Seller’s Net Sales of Product sold in the Territory during each calendar quarter after the first twelve full calendar months after Seller’s First Commercial Sale pursuant to the Seller Launch.

2.3.5 The Compensatory Payments shall be paid within 30 days of the end of each calendar quarter following Seller’s First Commercial Sale pursuant to the Seller Launch. Each Compensatory Payments payment shall include a report setting forth in reasonable detail the amount of and the basis for such payment, including a calculation of Seller’s Net Sales (including itemizing all deductions to gross sales) for such quarterly period. With respect to any payment due as a result of the [***] minimum Compensatory Payments amounts set forth in Sections 2.3.4(a) and (b) above, such payment shall be made within 30 days of the end of the calendar quarter that contains the sixth month of the applicable six month period for which the [***] minimum Compensatory Payments amount accrued. Any payments not made within the specified period of time for payment shall incur an interest charge at the rate of the Overdue Interest Amount on such overdue amounts, excluding any amounts that are subject to a bona fide dispute between the parties.

2.3.6 Subsequent Suspension of a Seller Launch. In the event that, within 30 days of Seller’s First Commercial Sale pursuant to a Seller Launch, Seller either voluntarily or as a result of an order of the FDA or any court having competent jurisdiction ceases to sell in and withdraws the Product from the market in the Territory, Seller’s obligation to pay the Compensatory Payments pursuant to such Seller Launch shall immediately terminate as of the date of such withdrawal and this Agreement shall be automatically and immediately reinstated and be in full force and effect on and after the date of such withdrawal pursuant to its terms. Without limiting the generality of the preceding sentence, in the event that, at any time after such withdrawal of the Product, Seller determines to engage in a new commercial launch of the Product in the Territory, Seller shall provide to Purchaser a Launch Notice pursuant to Section 2.3.1 above and the remaining provisions of this Section 2.3 shall again apply to such new Launch Notice. In the event that Seller after such withdrawal of the Product delivers to Purchaser a Non-At-Risk Launch Notice or Purchaser notifies Seller that it will engage in an At-Risk Launch in accordance with Section 2.3.2 above following receipt of an At-Risk Launch Notice, in addition to the payment of the milestone payment under Section 3.1(b) required in connection therewith, Purchaser shall refund to Seller any amount of the Compensatory Payments previously paid to Seller within 10 days of receipt by Purchaser of such Non-At-Risk Launch Notice or receipt by Seller of Purchaser’s notice of intention to engage in an At-Risk Launch. In the event that Purchaser determines to not engage in such subsequent At-Risk Launch and Seller commences a subsequent Seller Launch, (i) each of the [***] minimum Compensatory Payments amounts under Sections 2.3.4(a) and (b) shall be reduced to an amount equal to [***] multiplied by a fraction, the numerator of which is the number of months of Product sales under all previous Seller Launches pursuant to which Seller paid Compensatory Payments and the denominator of which is six and (ii) the Maximum Compensatory Payments shall be reduced by the amount all Compensatory Payments previously paid to Purchaser.

2.4 Termination of Agreement Relating to Commercial Launch.

2.4.1 In addition to Purchaser’s termination rights set forth elsewhere herein, Purchaser shall be entitled to terminate this Agreement as set forth in this Section 2.4.1:

(a) Purchaser may terminate this Agreement after June 30, 2006, upon 30 days prior written notice to Seller, if Seller shall not have obtained a Favorable Resolution on or prior to June 30, 2006, so long as such termination notice is received by Seller on or before July 15, 2006.

(b) Provided that Purchaser shall not have notified Seller that it will engage in an At-Risk Launch prior thereto, Purchaser may terminate this Agreement after June 30, 2006, upon 30 days prior written notice to Seller, if after June 30, 2006 an Adverse Resolution then exists, so long as such termination notice is received by Seller within 15 days after the later of June 30, 2006 or the date Purchaser is notified of such Adverse Resolution. Seller shall provide written notice to Purchaser within 10 days of any Adverse Resolution. For purposes of clarification, Purchaser’s right to terminate this Agreement under this Section 2.4.1(b) shall not apply after Seller’s delivery to Purchaser of a Launch Notice, unless such Launch Notice is an At-Risk Launch Notice, and then only in the event that this Agreement remains in effect pursuant to Seller’s determination to not engage in a Seller Launch under Section 2.3.2 or this Agreement is reinstated following a Product withdrawal pursuant to Section 2.3.6.

(c) Purchaser may terminate this Agreement after June 30, 2007, upon 30 days prior written notice to Seller, if Seller shall not have delivered to Purchaser a Launch Notice on or before June 30, 2007, so long as such termination notice is received by Seller on or before July 15, 2007.

As permitted by Applicable Law, Purchaser and Seller shall cooperate in creating arrangements with their respective drug wholesalers and other customers necessary to implement the foregoing. From time to time upon request, each party shall provide the other with reasonable access to all information in its possession and control (or which is reasonably obtainable) to confirm the ultimate customer of the Products sold by it to drug wholesalers or other Persons. To the extent Seller sells any Products to drug wholesalers or other Persons that are ultimately purchased by any customer included in items (a)-(e) of Section 1.46, Seller shall pay Purchaser its portion of the Gross Profits (i.e., Seller’s Net Sales less the imputed Transfer Price of the Product times Purchaser’s then applicable portion of the Gross Profit Split) attributable to such sales by Seller plus the Overdue Interest Amount on the amount due from the date of the sale to the date of payment.

All such refunds shall be made by Seller within 30 days after the applicable termination date; provided that, such amount remaining outstanding shall bear simple interest at the rate of the Overdue Interest Amount commencing on the date such amount is due and payable (i.e., 30 days after the applicable termination date) until paid in full; and provided further that, if Seller does not have at the time the available funds to repay Purchaser such amount, such amount shall be repaid no later than one year from the applicable termination date. If payment is not made within 30 days of termination, upon request of Purchaser, Seller shall (as soon as reasonably practicable) provide Purchaser with reasonable security for repayment of any milestone payments not paid when due, including potentially, assignment of product revenues or a lien on other assets.

ARTICLE 4

PRICING

4.1 Transfer Price.

4.1.1 The transfer price (“Transfer Price”) payable by Purchaser for Product delivered by Seller shall be a payment equal to the product of (a) the number of units of Product delivered by Seller to Purchaser pursuant to the applicable Purchase Order (including the Initial Purchase Order), multiplied by (b) [***] per unit, regardless of dosage strength (the “Unit Price”). Notwithstanding the foregoing, on and after the [***] of the First Commercial Sale, Seller may increase the Unit Price during each twelve month period (which begins on an anniversary of the First Commercial Sale), effective upon 30 days prior written notice to Purchaser (or upon the later resolution of any disputed price increase, except if such dispute is resolved in Seller’s favor in which case the Unit Price increase shall be effective 30 days from Seller’s original notice thereof to Purchaser), by (i) the actual per unit increase in Seller’s raw materials costs (the “Raw Material Costs”) for the Product (including the costs of plunger rods, needle stick prevention devices, syringes, Packaging and other ingredients and materials used to manufacture and process the Product) over the 12 month period preceding the date of Seller’s notice of such price increase not to exceed (subject to Section 4.1.2) [***] of the amount

of Seller’s Raw Material Costs as at the beginning of the 12-month period immediately prior to such price increase and (ii) the actual per unit increase in Seller’s direct labor costs (“Labor Costs”) for the Product over the prior 12 month period preceding the date of Seller’s notice of such price increase not to exceed (subject to Section 4.1.2) [***] of the amount of the Seller’s Labor Costs as at the beginning of the 12-month period immediately prior to such price increase. Seller shall provide Purchaser with reasonable documentation evidencing the applicable increases in Seller’s Raw Material Costs and Labor Costs with Seller’s notice of the price increase. Purchaser may dispute in good faith any increase to the Unit Price pursuant to this Section 4.1.1 by written notice to Seller within 10 days of Purchaser’s receipt of Seller’s notice thereof. If the dispute is not resolved within 30 days of Purchaser’s dispute notice to Seller, then Purchaser may elect to seek resolution of the dispute pursuant to the provisions of Section 4.5 by providing written notice to Seller of such election. If Purchaser does not provide Seller such written notice within 10 days after the aforementioned 30 day period, then the dispute shall be deemed resolved in Seller’s favor.

4.1.2 At the written request of Seller on and after the [***] of the First Commercial Sale, the parties shall discuss increases in the Unit Price in excess of the respective [***] limitations provided in Section 4.1.1 to the extent such increases are due to increases in Raw Material Costs and/or Labor Costs attributable to changes required by Applicable Law or governmental authority, including FDA, as provided in Section 6.2.1. Any such request for an increase in the Unit Price in excess of the respective [***] limitations provided in Section 4.1.1 shall be reasonably considered in good faith by Purchaser but shall not be implemented without Purchaser’s written consent (which shall not be unreasonably withheld, delayed or conditioned). In the event Seller’s Raw Material Costs and/or Labor Costs increase by [***] or more during any twelve month period as a result of changes required by Applicable Law or governmental authority, including FDA, as provided in Section 6.2.1 (based on reasonable documentation) and Purchaser does not consent to a corresponding increase as requested by Seller in the Unit Price in excess of the respective [***] limitations (as the case may be) provided in Section 4.1.1 within [***] of the date of Seller’s written request for such increase, then Seller shall (by written notice within [***] of the date of Seller’s written request for such increase) have the right to terminate this Agreement upon [***] written notice to Purchaser.

4.2 Gross Profit Split.

4.2.1 Purchaser shall pay to Seller, as additional consideration for Seller’s supply of Product hereunder to Purchaser, the following portion of Gross Profit (the “Gross Profit Split”):

(a) 60% percent of the Gross Profit for so long as there are [***] Competitive Products;

(b) 55% percent of the Gross Profit for so long as there is (i) [***] Competitive Product being sold and distributed to Purchaser Customers in the Territory or (ii) [***] Competitive Product being sold and distributed to customers in the Territory other than Purchaser Customers and as a result of the sale and distribution of such Competitive Product, Purchaser’s Net Sales for the last completed calendar quarter are more than [***] less than Purchaser’s Net Sales for the calendar quarter immediately preceding the last completed calendar quarter; and

(c) 50% percent of the Gross Profit for so long as there are (i) [***] or more Competitive Products being sold and distributed to Purchaser Customers in the Territory or (ii) [***] or more Competitive Products being sold and distributed to customers in the Territory other than Purchaser Customers and as a result of the sale and distribution of such Competitive Products, Purchaser’s Net Sales for the last completed calendar quarter are more than [***] less than Purchaser’s Net Sales for the calendar quarter immediately preceding the last completed calendar quarter.

4.2.2 Seller’s Gross Profit Split shall be calculated and paid to Seller quarterly, within 30 days after quarter end. Any adjustment to the Gross Profit Split as required from time to time due to an increase or decrease in the number of Competitive Products or Purchaser’s Net Sales shall be effective upon the day of the calendar month in which the change of number of Competitive Product(s) occurred in the case of Section 4.2.1(b)(i) and (c)(i) above and upon the first day of the immediately succeeding calendar month after the calendar month in which the change in Purchaser’s Net Sales triggered an adjustment to the Gross Profit Split in the case of Section 4.2.1(b)(ii) or (c)(ii) above. Notwithstanding anything herein to the contrary and by way of clarification, any adjustment to the Gross Profit Split resulting from a change in the number of Competitive Products or Net Sales shall change only the Gross Profit Split of Product having the same dosage strength as that of the relevant Competitive Product(s) then being sold and distributed in the Territory. Each party shall provide the other party prompt written notice of any adjustment to the Gross Profit Split which the notifying party believes is warranted as a result of a change in the number of Competitive Products or Purchaser’s Net Sales. With such notice, the notifying party shall provide an explanation to the other party as to the reasons why such adjustment is warranted and shall provide the other party any documentation in notifying party’s possession or control which supports the notifying party’s basis for such adjustment.

4.3 Shipping Terms. The prices charged by Seller to Purchaser shall be FCA (Incoterms 2000), Seller’s designated manufacturing facility.

4.4 Payment Terms.

4.4.1 The Transfer Price for the Product shall be paid within 30 days of the date of the applicable invoice for such Product.

4.4.2 The Gross Profit Split shall be paid within 30 days of the end of each calendar quarter, with a report setting forth in reasonable detail the amount of and the basis for such payment, including a calculation of Purchaser’s Net Sales (including itemizing all deductions to gross sales), Gross Profit and the Gross Profit Split (as applicable on a dosage strength basis) for such quarterly period [***].

4.4.3 Any payments not made within the specified period of time for payment shall incur an interest charge at the rate of the Overdue Interest Amount on such overdue amounts, excluding any amounts that are subject to a bona fide dispute between the parties. In addition, Seller may withhold shipment of Product to Purchaser if Purchaser has failed to make any payment required under this Agreement (except for any amounts that are subject to a bona fide dispute) after the due date for such payment. All payments shall be made in U.S. dollars through electronic transfer of funds or other wire transfers.

4.5 Audit Rights. Purchaser with respect to Section 2.2.3 and this Article 4 and Seller with respect to Sections 2.3.4 and 4.1 shall keep complete and accurate books and records for purposes of documenting the amount and calculations of, as applicable, Net Sales [***], Gross Profit, Gross Profit Split, the Compensatory Payments and, to the extent it is a basis for an increase in the Transfer Price pursuant to Section 4.1, increases in Raw Material Costs and Labor Costs. Said books of account shall be kept at Purchaser’s or Seller’s principal place of business, as applicable. Upon reasonable notice, each Purchaser or Seller, as applicable, at its expense, shall have the right to have an independent public accounting firm (reasonably acceptable to the other party) obtain access to the other party’s financial records, during reasonable business hours, solely for the purpose of verifying such party’s payments hereunder; provided, however, that this right may not be exercised more than once in any calendar year (unless a prior audit by the audited party in such calendar year reveals a discrepancy of the greater of 5% of the payment(s) audited or $25,000 in any calendar quarter and then the auditing party may exercise its audit right no more than twice during such calendar year). The accountants engaged by the auditing party shall report to the auditing party only information of the audited party related to the accuracy of the audited party’s calculations then being audited. The findings of the accountants engaged by the auditing party shall be final and binding upon the parties hereto, and the payments attributable to any particular period may only be audited once for such period. Any underpayment or overpayment of the amount due hereunder due to a miscalculation of such amount shall be paid within 30 days after the delivery of a written accountants’ report to each party. In the event any such audit reveals a shortfall greater than 5% of the payment(s) audited or $25,000 in any calendar quarter, then the reasonable costs of the accountants engaged by the auditing party to perform such audit shall be reimbursed by the audited party. Any underpayment or overpayment amount paid pursuant to this Section 4.5 shall accrue interest on such amount from the original due date at the Overdue Interest Amount.

ARTICLE 5

LAUNCH QUANTITIES, FORECASTS, ORDERS

5.1 Initial Purchase Order; Launch Quantities. Within 5 days following receipt of a Non-At-Risk Launch Notice by Purchaser or delivery to Seller of Purchaser’s notice that it will engage in an At-Risk Launch, Purchaser shall deliver to Seller an initial binding order (the “Initial Purchase Order”) for the quantity of Product required for Purchaser’s commercial launch of the Product consistent with Purchaser’s then current Forecast; provided that, such quantity shall not exceed (without the prior written consent of Seller, which may be withheld in its sole discretion) [***] units of Product if the First Commercial Sale occurs in calendar year 2005 or [***] of the then existing Maximum Annual Product Units if the First Commercial Sale occurs in any calendar year after 2005 (the “Launch Quantities”). Subject to the terms of this Agreement, Seller shall use Commercially Reasonable Efforts to supply the Product to Purchaser in the Launch Quantities by no later than the delivery dates indicated in the Initial Purchase Order, which delivery dates shall be no sooner than 90 days after the date of the Initial Purchase Order unless Seller consents thereto. Seller shall thereafter use Commercially Reasonable Efforts to supply to Purchaser such additional quantities of the Product as ordered by Purchaser hereunder pursuant to Section 5.3.

5.2 Forecasts. Beginning at least 6 months prior to the anticipated date of FDA approval of the Product’s ANDA and at least 90 days prior to each calendar quarter thereafter, Purchaser shall provide to Seller a rolling 12-month forecast (each a “Forecast”) of the quantities of the Product to be purchased by Purchaser on a monthly basis. Without limiting the foregoing, in addition to the

above Product quantities, each Forecast delivered by Purchaser prior to its First Commercial Sale shall include the Launch Quantities. Forecasts shall be in good faith and non-binding, provided, however, that (a) on and after Purchaser’s delivery of its Initial Purchase Order to Seller, the first three months of each Forecast shall be binding on Purchaser, and shall constitute Purchaser’s firm order for the quantity of Product set forth in such Forecast; and (b) forecasted quantities of the Product for the fourth, fifth and sixth months forecasted thereunder shall not increase by more than 25% from the quantities forecasted for such months in the preceding Forecast without Seller’s prior written consent (not to be unreasonably withheld or delayed).

5.3 Orders. Except for the Initial Purchaser Order, Purchaser shall deliver to Seller purchase orders (“Purchase Orders”) for the Product no later than 90 days before the date that the Products for such Purchase Order are required to be delivered to Purchaser and provided such Purchase Orders are for the binding portion (i.e., the first three months) of the then current Forecast in accordance with Section 5.2, Seller shall accept such Purchase Orders. Subject to Section 5.6, Seller shall use Commercially Reasonable Efforts to satisfy Purchase Orders for amounts in excess of those forecasted for the binding portion of the then current Forecast pursuant to Section 5.2; provided that in no event shall Seller be required to add to its existing manufacturing capacity of its facility(ies) for the Product in order to satisfy Purchaser’s Purchase Orders. Each such Purchase Order shall be firm and shall specify the quantity of the Product ordered, the date on which such Product shall be delivered and the delivery address. Product shall be ordered by Purchaser in no less than full batch increments.

5.4 Shipping Reports. On or promptly after the date of each shipment of Product, Seller shall submit to Purchaser, via facsimile, a packing slip containing the ship date, trailer number, contents and quantities of each shipment and invoice for the Transfer Price.

5.5 Standard Forms; Conflicts. In ordering and delivering the Product pursuant hereto, Seller and Purchaser may use their standard forms (including Purchase Orders, invoices, sales acknowledgments, etc.), but nothing in those forms shall be construed to modify, amend or supplement the terms of this Agreement and, in case of any conflict herewith, the terms of this Agreement shall control, and any additional or modified terms contained in any such Purchase Order or other form shall be null and void and shall not be binding upon the receiving party.

5.6 Capacity Allocation.

5.6.1 Notwithstanding anything herein to the contrary or anything to the contrary in any Purchase Order or Forecast, Seller shall not be obligated to supply Purchaser (regardless of amounts ordered by Purchaser), more than the then applicable Maximum Annual Product Units during a twelve month period. Without limiting the foregoing, any Purchase Order or Forecast submitted by Purchaser hereunder for more than the then applicable Maximum Annual Product Units shall, to the extent of the excess, be deemed rejected by Seller, unless expressly accepted by Seller in writing. As used herein, the term “Maximum Annual Product Units” shall mean for the period ending twelve full calendar months from the First Commercial Sale and for each twelve month period thereafter, [***] of the total units of branded and generic Lovenox® product (including the brand name product, the Product, any Authorized Generic Product and any Competitive Product) sold for distribution into the Territory for the immediately preceding calendar year as reported by IMS Health (or such other nationally recognized data compilation source as mutually agreed); provided that, if the First Commercial Sale occurs during calendar year 2005, then the Maximum Annual Product Units for the period ending twelve full calendar months from the First Commercial Sale shall be deemed to be [***] units of Product. For each twelve month period beginning after the First Commercial Sale (other than as provided above if the First Commercial Sale occurs in calendar year 2005), the Maximum Annual Product Units shall be established as soon as data from IMS Health (or such other nationally recognized source as mutually agreed) for the immediately preceding calendar year becomes available to the parties and once the Maximum Annual Product Units for the then current twelve month period is established, it shall be effective retroactively to the beginning of and shall be fixed through such twelve month period. Without limiting the foregoing, but by way of example: If the First Commercial Sale occurs on September 1, 2005, then the Maximum Annual Product Units for the twelve month period ending with August 31, 2006 would be [***] units of Product. As a result, Purchaser would have no right to order or purchase, and Seller would have no obligation to supply, more than [***] units of Product during the twelve month period ending August 31, 2006. Assuming that [***] total units of branded and generic Lovenox® product were sold for distribution into the Territory for the 2005 calendar year as reported by IMS Health, then the newly established Maximum Annual Product Units for the twelve month period ending August 31, 2007 would be [***] units of Product (i.e., [***] units). As a result, Purchaser would have no right to order or purchase, and Seller would have no obligation to supply, more than [***] units of Product during the twelve month period ending August 31, 2007. The foregoing process would be repeated once each twelve month period thereafter to establish the Maximum Annual Product Units for the then current twelve month period. At Purchaser’s request from time to time, the parties shall discuss increasing the then existing Maximum Annual

Product Units based on then existing market conditions, Seller’s manufacturing capacity and other relevant factors. Seller shall reasonably consider Purchaser’s request and its reasons for an increase in the then existing Maximum Annual Product Units; provided that, Seller shall have no obligation to agree to (and may reject in Seller’s sole discretion and without liability) any increase requested by Purchaser in the then existing Maximum Annual Product Units.

5.6.2 In the event that Seller’s inability (including any inability as a result of a Force Majeure Event) to satisfy any Purchase Order accepted pursuant to Section 5.3, in whole or in part, is due to a shortage of production capacity or raw materials, then, subject to the terms and conditions of this Agreement, including Section 5.6.1 above, Seller shall give priority to Purchaser’s Purchase Orders, and satisfy deliveries of amounts ordered consistent with Section 5.3 prior to fulfilling order for Product of any other Person, for up to (i) [***] units of Product to be delivered to Purchaser pursuant to its Purchase Orders for the period ending six full calendar months after the First Commercial Sale and (ii) [***] units of Product to be delivered to Purchaser pursuant to its Purchase Orders during each six month period thereafter and for any Product to be delivered to Purchaser pursuant to its Purchase Orders during such six month period in excess of the foregoing [***] unit amount, [***] of Seller’s units of its finished inventory of Product produced during the applicable period in excess of [***] units shall be allocated to fulfill any such remaining outstanding Purchase Orders.

ARTICLE 6

Seller reserves the right to make such changes unilaterally; provided, however, that Seller will consult with Purchaser prior to making such changes; and provided further that, Seller shall obtain Purchaser’s prior written consent (which will not be unreasonably withheld or delayed) for any changes that would materially affect storage or transportation of the Product after delivery to Purchaser. The cost of making a discretionary change shall be borne solely by the party initiating the change or as otherwise mutually agreed to in writing by the parties. In the event any such changes initiated by Purchaser increase Seller’s costs of manufacturing and supplying the Product to Purchaser, at Seller’s request, the parties shall discuss and agree in good faith to an equitable adjustment of the Unit Price to account for such increase in costs.

6.2.3 Product Labeling. The Products supplied to Purchaser will include Purchaser’s NDC number and be packaged in labeling and artwork approved by Purchaser to indicate Purchaser as a distributor of the Product. In order for Purchaser to include in the Product Label Purchaser Trademarks or similar changes indicating Purchaser as a distributor of the Product; (a) upon Purchaser’s request, Seller shall provide Purchaser with the Label artwork and text in electronic format, (b) Purchaser may update such artwork and text to include Purchaser Trademarks and such other similar changes as desired by Purchaser to indicate Purchaser as a distributor of the Product, and (c) Purchaser’s costs in connection with the foregoing shall be at its sole expense. Thereafter, Seller shall make all necessary arrangements, at its expense (except as provided in Section 6.2.1 above), to have changed Labels or Labeling printed and shall provide printer’s proofs to Purchaser for Purchaser’s review. Purchaser shall, within two (2) weeks of receipt of said printer’s proofs, provide written notice to Seller of Purchaser’s approval of such proofs in the form submitted by Seller (which approval shall not be unreasonably conditioned, withheld or delayed) or with such corrections thereto (in Purchaser’s reasonable judgment) as included in Purchaser’s notice. Thereafter, Seller shall incorporate in such Labels and Labeling Purchaser’s requested corrections thereto, if any, and shall supply Purchaser with examples of such Product Labels and Labeling for Purchaser’s regulatory filings; provided, however, that, if Seller shall not agree with Purchaser’s requested corrections, Purchaser and Seller shall consult in good faith to reach a resolution mutually agreeable to Purchaser and Seller.

6.3 Trademarks. All trademarks, tradenames and packaging graphics used by Purchaser in connection with its sale and distribution of the Product to Purchaser Customers in the Territory (collectively, the “Purchaser Trademarks”) shall be chosen by Purchaser in its sole discretion, subject to the terms and conditions of this Agreement. Purchaser shall be responsible for any and all liabilities which may arise from Purchaser’s use of the Purchaser Trademarks (including any allegations of intellectual property infringement related thereto and any liabilities related to prescription errors related to such trademark usage). Unless consented to in writing by Seller, Purchaser shall not use any trademark, tradename, company name, or copyright of Seller in connection with the distribution, marketing or sale of the Product.

6.4 Certificate of Analysis. Each shipment of the Product to Purchaser shall be accompanied by a certificate of analysis prepared by an authorized representative of Seller certifying that the Product in the shipment has been tested in accordance with the ANDA for such Product, meets the Specifications and was manufactured in material compliance with cGMP (for the avoidance of doubt any non-compliance that would affect Purchaser’s sale or distribution of the Product hereunder shall be considered material). Seller shall deliver such certificate of analysis by facsimile or overnight delivery to Purchaser’s distribution facility as designated by Purchaser.

6.5 Expiry Dating. Except as otherwise agreed to in writing by Purchaser, all Product shipped to Purchaser, on the date of shipment by Seller, shall have a shelf-life of at least the approved dating of the Product (per the Product’s ANDA) [***].

6.6 Stability Testing. Seller shall maintain a stability testing program for the Product and provide Purchaser with an annual product review thereon. At least one batch per year of Product shall be included in the stability program.

6.7 Annual Report. At Seller’s written request, Purchaser will supply distribution information and other information reasonably requested by Seller, for the purposes of inclusion into Seller’s Annual Report to FDA.

ARTICLE 7

7.1 Term. Subject to Article 8, the term of this Agreement shall commence on the Effective Date and remain in effect for a period of 7 years from the date of Purchaser’s First Commercial Sale. Notwithstanding the foregoing, Purchaser shall have the option to renew this Agreement for an additional term of 3 years from the date of the expiration of the initial term by providing Seller Purchaser’s irrevocable written notice thereof 12 months prior to the end of the initial term.

ARTICLE 8

This Agreement may be terminated, prior to the expiration of its term, by either party by giving written notice of its intent to terminate and stating the grounds therefor if the other party shall have materially breached or materially failed in the observance or performance of any representation, warranty, guarantee, covenant or obligation under this Agreement. The party receiving the default notice shall have 30 days from the date of receipt thereof to cure the breach or failure, except in the case of a breach of an obligation to pay money, in which case such cure period shall be 10 days; provided, however, that nonpayment in connection with a good faith dispute of the amount in dispute shall not be considered a breach hereof so long as once such dispute is resolved, payment of any amounts owing is made within 5 days of such resolution. If a breach (other than a breach of an obligation to pay money) is not curable within such 30 day period, then the non-performing party shall have an additional 30 days within which to cure such breach so long as the non-performing party is diligently working towards a remedy for such breach. In the event such breach or failure is cured in accordance with the provisions of this Section 8.1, the default notice shall become of no effect. In the event such breach or failure is not cured in accordance with the provisions of this Section 8.1, then this Agreement shall terminate immediately upon written notice to the defaulting party.

8.2 Insolvency, Etc.

Notwithstanding the foregoing (unless Purchaser has not ordered at least the Minimum Annual Product Units), Seller’s right to terminate this Agreement pursuant to this Section 8.4 is conditioned upon Seller fulfilling all of Purchaser’s Purchase Orders for Product on a timely basis during the twelve month period upon which Seller’s exercise of its termination rights under this Section 8.4 is based. As used herein, the term “Minimum Annual Product Units” shall mean [***] units of Product during any twelve month period beginning after the First Commercial Sale there are no Authorized Generic Product or Competitive Product being sold and distributed in the Territory and [***] units of Product during any twelve month period beginning after the First Commercial Sale in which there are one or more Authorized Generic Products or Competitive Products being sold and distributed in the Territory (which adjustment shall be effective upon the date of market entry of such Authorized Generic Product or Competitive Product); provided that, in the event of any adjustment to Minimum Annual Product Units during any rolling twelve month period, the Minimum Annual Product Units existing immediately prior to and after such adjustment shall be prorated as of the effective date of such adjustment for the purpose of calculating the Minimum Annual Product Units for such twelve month period.

8.5 Termination Due to Third Party Infringement Claim. On and after Purchaser’s First Commercial Sale, Purchaser may terminate this Agreement upon 30 days prior written notice to Seller in the event a Third Party Infringement Claim (other than with respect to the use of Purchaser Trademark) is made against Purchaser or its Affiliates so long as such termination notice is provided to Seller within 15 days of Purchaser receiving written notice of such Third Party Infringement Claim.

Purchaser shall use Commercially Reasonable Efforts, within 20 days after receipt of any shipment of Product, to notify Seller in writing of the existence and nature of any non-compliance with the Product Warranty observable from a visual inspection.

If Purchaser notifies Seller of defective Product, then Seller shall have a reasonable opportunity to inspect such defective Product and provide Purchaser with detailed written instructions to return or dispose of such defective Product at Seller’s expense. Whether or not Seller agrees with Purchaser’s basis of rejection, Seller shall, at Purchaser’s request, use Commercially Reasonable Efforts to promptly replace the rejected Product. Purchaser shall pay the Transfer Price, and, to the extent Purchaser’s Net Sales derive from the sale of such Product, the applicable Gross Profit Split, for any Product shipped by Seller that replaces Product rejected by Purchaser hereunder. In accordance with Section 10.2 below, Purchaser shall not be obligated to pay for any properly rejected Product and any such payment shall be promptly returned to Purchaser if Seller agrees with Purchaser’s notice of non-compliance with respect to such rejected Product or such rejected Product is deemed by the independent third-party laboratory to be not in compliance with the Product Warranty. Purchaser shall not destroy, return or otherwise dispose of the rejected Product until written notification is received from Seller.

10.2 Independent Testing. If Seller disagrees with Purchaser’s notice of non-compliance as to Product testing Specifications of the Product to the Product Warranty, the Product shall be submitted to an independent third-party laboratory, mutually and reasonably acceptable to both parties, for analytical testing to determine the extent of the Product’s compliance or non-compliance to the Product Warranty. All costs associated with such third-party laboratory testing shall be at Purchaser’s expense, and Purchaser shall be required to pay the Transfer Price and, in the event Purchaser’s Net Sales derive from the sale of such Product, the applicable Gross Profit Split, for all rejected Product (irrespective of whether Seller has replaced such Product), unless Seller agrees with Purchaser’s notice of non-compliance or the tested Product is deemed by such third-party laboratory to be not in compliance with the Product Warranty, in which case all such costs associated with such third-party laboratory testing, including reimbursement of freight and disposition costs, shall be promptly reimbursed by Seller to Purchaser and Purchaser shall not be obligated to pay for such rejected Product and any such payment shall be promptly returned to Purchaser.

REGULATORY MATTERS

11.1 Adverse Event Reporting; Product Complaints. Purchaser shall have the responsibility in the Territory for complying with all regulatory filings, reporting requirements and other matters which relate solely to Purchaser acting as a distributor of the Product to Purchaser Customers in the Territory and Seller shall cooperate with Purchaser as reasonably necessary to

accomplish the foregoing. All other regulatory reporting matters (including investigating, evaluating and reporting Adverse Events and other Product complaints) shall be Seller’s responsibility. In this regard, Seller shall be responsible for all reporting to regulatory authorities of all Adverse Events associated with the use of Product. Purchaser shall notify Seller of any report of an Adverse Event concerning the Product within five (5) calendar days of receipt of the report and provide Seller with information as required by Applicable Laws or as reasonably requested by Seller. Purchaser shall cooperate with Seller as necessary to report such Adverse Event when so required under Applicable Laws. Purchaser shall also notify Seller within 10 days of any complaints related to the Product of which it becomes aware regarding problems with the Product other than those associated with Adverse Events, and Seller shall meet and confer periodically with Purchaser with respect to Seller’s responses to such complaints and whether any remedial actions by Purchaser are indicated as necessary or appropriate by the pattern of complaints, which actions shall be at the expense of the party to the extent its improper acts or omissions caused such complaints.

11.2 FDA Communications. Purchaser and Seller agree to promptly notify the other party in the event they receive any communication or notice from the FDA with respect to the Product or an inspection of the facility where the Product is manufactured, Packaged or stored, and each party shall promptly provide a copy of such communications to the extent applicable to the Product to the other. The parties shall cooperate in good faith in responding to any such FDA inquiry or in making any report to the FDA with respect to the Product, but in all cases Seller shall have final authority for regulatory decisions concerning the Product and responsibility for all communications with the FDA.

11.3 Recalls.

11.3.1 In the event of any recall or seizure of any Product, other than a Purchaser Recall (as defined below) Seller shall, at the written election of Purchaser and at Seller’s sole cost, either:

(a) undertake Commercially Reasonable Efforts to replace the amount of Product recalled or seized; or

(b) give credit to Purchaser against outstanding receivables due from Purchaser in an amount equal to the amount paid by Purchaser for the Product (including any Gross Profit Split paid to Seller on such Product) so recalled or seized or otherwise owing by Purchaser hereunder;

plus reimburse (or, at the written election of Purchaser, credit) Purchaser for the aggregate and reasonable transportation costs, taxes, freight insurance, handling and reasonable and verifiable out-of-pocket costs incurred by Purchaser in respect of such recalled or seized Product.

11.3.2 In the event of any recall or seizure of any Product occurring primarily as a result of any breach of this Agreement by, or negligent acts of omissions or intentional misconduct of, Purchaser or its Affiliates (a “Purchaser Recall”), (i) if such Purchaser Recall is classified by FDA as a Class I recall, Seller shall be responsible (as between Purchaser and Seller) for such recalled or seized Product and shall bear all costs of such recall or seizure, (ii) if such Purchaser Recall is classified by FDA as a Class II recall, Seller shall be responsible (as between Purchaser and Seller) for such recalled or seized Product and the parties shall share equally all costs of such recall or seizure and (iii) if such Purchaser Recall is classified by FDA as a Class III recall, Purchaser shall be responsible (as between Purchaser and Seller) for such recalled or seized Product and shall bear all costs of such recall or seizure, including reimbursement of Seller of any reasonable and verifiable out-of-pocket costs incurred by Seller related to the recall or seizure of such Product. Purchaser’s costs with respect to any Purchaser Recall as set forth above shall not be deducted in connection with the calculation of Purchaser’s Net Sales or Gross Profit hereunder.

11.3.3 For purposes of this Section 11.3, “recall” shall mean (i) any action by Seller, Purchaser, any Affiliate of either to recover title to or possession of any Product sold or shipped and/or (ii) any decision by Purchaser not to sell or ship Product to third parties which would have been subject to recall or seizure if it had been sold or shipped, in each case taken in the good faith belief that such action was appropriate or required under the circumstances. For purposes of this Section 11.3, “seizure” shall mean any action by any government agency to detain or destroy any Product. Notwithstanding anything to the contrary in this Section 11.3, Seller shall have final authority with respect to any recall of the Product and neither Purchaser nor its Affiliates shall initiate any recall of the Product without Seller’s prior written approval (such approval not to be unreasonably conditioned, withheld or delayed).

11.3.4 Seller and Purchaser shall keep the other fully informed of any notification or other information, whether received directly or indirectly, that might affect the marketability, safety or effectiveness of the Product, or which might result in liability issues or otherwise necessitate action on the part of either party, or which might result in recall or seizure of any Product. Purchaser shall maintain records of all sales of Product and customers reasonably sufficient to adequately administer a recall or seizure for the longer of three years after termination or expiration of this Agreement or the period required by Applicable Law. Seller will be responsible for assuring that such recall is closed-out with the FDA, unless the FDA shall otherwise require.

11.4 Inspections.

11.4.1 Seller shall use Commercially Reasonable Efforts to maintain and operate the manufacturing facility designated in the ANDA, and to implement such quality control procedures, so as to cause Seller to be able to perform its obligations hereunder. Upon Purchaser’s written request and at its expense, Seller shall permit quality assurance representatives of Purchaser (reasonably acceptable to Seller) to inspect such manufacturing facility, at all times accompanied by a representative of Seller, upon reasonable notice, during normal business hours and on a confidential basis. Such inspection shall be limited to an assessment of such facility’s compliance with cGMP and other quality assurance standards as such relate to the manufacture of the Product. Seller shall also permit Purchaser reasonable periodic visits to discuss and review manufacturing and supply issues with management of Seller.

11.4.2 In the event Seller’s manufacturing, Packaging, testing or storage facility producing the Product hereunder is inspected by representatives of any federal, state, or local agency in connection with Seller’s manufacture, Packaging, testing or storage of Product, then Seller shall notify the Purchaser promptly upon learning of such inspection, and shall, within 10 days of such notice, supply Purchaser with copies of any correspondence or portions of correspondence which relate to the Product in Seller’s possession. If Seller is informed that a representative of any federal, state, or local agency will be conducting an audit of Seller’s manufacturing facility and such audit specifically relates to the Product, then Seller will, to the extent reasonably practicable, provide advance notice to Purchaser to permit Purchaser to observe and attend such audit. In the event Seller receives any regulatory letter or comments from any federal, state, or local agency in connection with its manufacture, Packaging, testing or storage of the Product requiring a response or action by Seller, including receipt of a Form 483 (Inspectional Observations) or a “Warning Letter,” Seller shall promptly following Seller’s receipt thereof, provide Purchaser with a copy of such communication which relate to the Product. At Seller’s request, Purchaser will provide Seller with any and all data or information reasonably required to prepare a response to such communication. Seller shall consult Purchaser with respect to any response relating to the Product; provided, however, that, as between Seller and Purchaser, Seller shall make the final determination as to any such response submitted to the regulatory authorities. Seller shall promptly provide Purchaser with a copy of any final response which relate to the Product after its submission to the regulatory authority.

11.4.3 Purchaser shall use Commercially Reasonable Efforts to maintain and operate any facility of Purchaser at which the Product is stored or distributed in compliance with cGMP and other quality assurance standards as such relate to the Product. Upon Seller’s written request and at its expense, Purchaser shall permit quality assurance representatives of Seller (reasonably acceptable to Purchaser) to inspect any facility of Purchaser at which the Product is stored or distributed. Such inspection shall be limited to an assessment of such facility’s compliance with cGMP and other quality assurance standards as such relate to the Product. In the event Purchaser is inspected or receives a regulatory letter or comments from any federal agency in connection with its sale or distribution of the Product, Purchaser shall notify Seller promptly upon learning of such inspection and/or provide Seller copies of such correspondence upon receiving such documentation. Seller shall have the right to, and at Purchaser’s written request shall, participate in that portion of such inspection relating to the Product. Regardless of whether Seller does participate as described above, Seller and Purchaser shall consult with respect to the response relating to the Product. Seller will provide Purchaser at Purchaser’s request with all data or information reasonably required to prepare a response relating to the Product, and Purchaser will promptly provide Seller with a copy of any final response submitted to the regulatory authority.

11.4.4 Seller will notify Purchaser within one day of any finished Product lot that results in a positive sterility test out of specification (OOS) condition, whether or not that lot was released or distributed, whether or not the positive sterility result was subsequently investigated and attributed to an assignable cause. In addition, Seller will notify Purchaser within one day of any stability test for the Product that results in an OOS condition relating to the Product Specifications, whether or not the OOS condition was subsequently investigated and attributed to an assignable cause. To the extent it is not reasonably practicable for Seller to provide notice within the one day period required by this Section, Seller will not be deemed to be in breach of this Agreement if it provides the required notice as soon as it is reasonably practicable. Seller will also provide quarterly reports to Purchaser of the number of lots of Product made and the number of lot failures during the preceding quarter and shall reasonably respond to any information requests relating thereto.

11.5 Sales and Marketing Activities. Purchaser shall be responsible for establishing a formal written program in compliance with the California Comprehensive Compliance Program pursuant to California Health and Safety Code Sections 119400 et. seq., on or before July 1, 2005, for all applicable activities of Purchaser and its Affiliates related to the Product which are subject to this code section. Upon request of Seller, Purchaser shall provide Seller with reasonable evidence of its compliance with this Section 11.5.

11.6 Cooperation. Seller shall provide reasonable assistance to Purchaser in its preparation and filing with appropriate regulatory agencies (both federal and state agencies related to reimbursement and health care insurance) of filings required for the marketing, and distribution of the Product to Purchaser Customers in the Territory by Purchaser. Seller and Purchaser shall cooperate in good faith to develop such necessary regulatory strategies which may be required for purposes of this Agreement, and to allow the Product to be listed on applicable formularies and other drug listings as reasonably requested by Purchaser, and making any applicable filings or registrations to allow the Product to be included on such formularies or listings, including Medicare and Medicaid.
