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 LovenoxÒ 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.

          2.4.2 Notwithstanding anything herein to the contrary, Purchaser’s sole remedy, whether in contract, tort or otherwise, for any failure by Seller to use Commercially Reasonable Efforts to obtain ANDA approval of the Product or any market exclusivity with respect thereto and/or any additional regulatory approvals necessary for the manufacture and supply of the Product and/or to obtain a Favorable Resolution shall be the termination of this Agreement as provided in this Section 2.4 and the right to any refund of the milestone payment under Section 3.2.

          2.4.3 This Agreement may be terminated by Seller upon 5 days written notice to Purchaser, if Purchaser shall have not effected Purchaser’s First Commercial Sale within 5 business days following Purchaser’s receipt of Launch Quantities in accordance with Section 2.3.3.

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. To the extent Purchaser sells any Product to drug wholesalers or other Persons that are ultimately purchased by any customer not included in items (a)-(e) of Section 1.46, then Purchaser shall pay to Seller all of the Gross Profit attributable to such sales by Purchaser plus the Overdue Interest Amount on the amount due from the date of the sale to the date of payment.

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) [***] 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.

               (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
