NABI grants to FRESENIUS a royalty-free, milestone-free, perpetual license to make, use, sell, offer for sale each Improvement that is either owned, or controlled with the right to sublicense, by NABI at any time during the term of this Agreement.

3. SPECIFIC OBLIGATIONS

3.1. Marketing

NABI shall use commercially reasonable efforts to market the Licensed Product in the Territory, after all necessary approvals have been obtained.

3.2. Sole Supply

A. Neither NABI nor any of its Affiliates shall, without the prior written consent of FRESENIUS (which may be granted or denied in the sole discretion of FRESENIUS)

(i) market, sell, manufacture for commercial sale or distribute in the Territory any Competitive Product, provided that, (x) the marketing, sale, manufacture for commercial sale and distribution of Competitive Products by NABI pursuant to Sections 3.4(B) or under circumstances to which Sections 14.4(A)(vi) or 14.4(B) apply shall not constitute a default under this Section 3.4 and (y) if NABI or any of its Affiliates has developed a Competitive Product (without violating their respective confidentiality obligations under this Agreement), NABI or its Affiliates may assign their rights (by sale or exclusive license for a

- 6 -

term which shall not be less than the remaining portion of the Initial Term (as defined in Section 11.1) plus five (5) years) in such Competitive Product to a third party (it being understood that neither NABI nor any of its Affiliates shall have any right of ownership or participation in such third party or the income or profit of such third party at any time other than through a royalty in connection with the license) and such action shall not constitute a breach of this Agreement for so long as NABI and its Affiliates do not engage in providing any direct or indirect marketing activity, or provide marketing direction or assistance, information or data in relation to such Competitive Product; or

Alternatively, the parties could agree upon another commercial relationship. If the parties are unable to agree upon acceptable terms regarding the ownership and exploitation of the Competitive Product in the circumstances described in this Section 3.4(b), if NABI’s rights to such Competitive Product in the Territory are not divested by NABI, or if such Competitive Product is not withdrawn from the market in the Territory, within twelve (12) months of its acquisition, then FRESENIUS will have the option at its discretion to terminate this Agreement pursuant to Section 11.2(A) below and reacquire all the rights to the Licensed Product in the Territory.

3.5. Transition

A. FRESENIUS will deliver or cause Enzon to deliver to NABI within ninety (90) days of the date hereof, the IND for the Licensed Product and all the clinical data for ATG which is in the possession or control of Enzon. If FRESENIUS shall fail to deliver such IND and clinical data for ATG within ninety (90) days hereafter, FRESENIUS shall promptly reimburse to NABI the milestone payment referred to in Section 7.8(A)(i) and NABI shall have the right to terminate this Agreement.

B. Promptly following the date hereof, NABI shall use commercially reasonable efforts to cooperate with Enzon and FRESENIUS in connection with the transition from Enzon to NABI of responsibility for the current study and program for ATG which had been conducted by FRESENIUS and/or Enzon with respect to the Territory.

C. Within [*****] of the Effective Date, FRESENIUS will send Enzon a letter requesting that Enzon immediately transfer the IND for the Licensed Product to NABI.

4. DEVELOPMENT

4.1. Development Plan

A. Within [*****] after the Effective Date (and taking into consideration the requirement of completing the task set forth in this Section 4.1(A) in order that the parties may comply with the obligations set forth in Section 4.1(B)), NABI will perform a CMC audit of the Facility and provide FRESENIUS with a detailed list of all items that NABI reasonably believes will need to be addressed and remedied in connection with the Facility before the first day of the second full calendar quarter prior to the planned submission to the US FDA of a Reviewable BLA in order that the Facility will be approved by the US FDA for the production of Licensed Product for marketing and distribution in the USA. The parties will negotiate the reasonableness, content and timing of the items specified by NABI during the thirty (30) days after delivery of the list to FRESENIUS. If the parties come to mutual agreement, then the items and time frames will be incorporated into and become part of the FRESENIUS Scheduled Obligations contemplated by Section 4.1(B) below. Failing such agreement each party will, upon the request of the other party, appoint an independent credentialed examiner or inspector familiar with FDA requirements for manufacturing facilities and request such appointed persons to designate a third

- 8 -

person who will act as the arbiter (the “Arbiter”). The Arbiter will be asked to resolve the differences between the parties and establish a definitive list of items to be remedied in the Facility in order that the same may comply with FDA requirements as then in existence for a manufacturing facility which will be examined in connection with a Reviewable BLA. Such determination will be final and binding on the parties and the cost for the services of the Arbiter shall be shared equally between the parties. FRESENIUS shall make such upgrades to the Facility as agreed by the parties or fixed by the Arbiter and as may be subsequently required by the US FDA during the term of this Agreement in order that the Facility will be, and will remain, approved by the US FDA for the production of Licensed Product for marketing and distribution in the USA.

B. Within [*****] after FRESENIUS delivers to NABI all of the clinical data required to be delivered pursuant to section 3.5(A), NABI shall meet with appropriate officials of the US FDA and determine the most efficient means of completing the studies which are necessary to commercialize the Licensed Product. Within sixty (60) days after the meeting with the US FDA, representatives of FRESENIUS and NABI shall meet with the Steering Committee and describe and discuss NABI’s strategy for development (clinical and regulatory) and commercialization of the Licensed Product in the Territory. The parties shall discuss in good faith the registration strategy and clinical studies that shall be undertaken to obtain marketing authorization in the Territory (starting with the U.S.) and establish specific milestones for: (i) the actions to be taken by NABI in order to assure efficient and expeditious approval of the Licensed Product for commercial sale in the U.S. and a time table for the realization thereof (collectively, “NABI’s Scheduled Obligations”); and (ii) based on the time table developed by the parties for the performance of various items necessary to obtain approval of the Licensed Product and depending on the time line for NABI to reasonably comply with NABI’s obligations, (x) the actions to be taken by FRESENIUS to upgrade the Facility to comply with the applicable US FDA manufacturing standards and the time table for the completion thereof as provided by Section 4.1(A) above; and (y) the date by which FRESENIUS will deliver to NABI whatever non-clinical (including toxicology and pharmacology (animal data)) package is required by the US FDA, which date may not be later than the first day of the second full calendar quarter prior to the planned submission to the US FDA of a Reviewable BLA (collectively the “FRESENIUS Scheduled Obligations”). Upon agreement and approval by the Steering Committee, the actions comprising and the time lines for completing the NABI Scheduled Obligations and the FRESENIUS Scheduled Obligations shall be a part of this Agreement as if set forth herein. The registration strategy shall include continuation of the lung transplant study currently underway and shall, at the option of NABI, specify whether the clinical studies for the SOT indication and the SCT indication shall be undertaken sequentially or contemporaneously in light of the estimated cost thereof and the mutual intention of the parties that the registration strategy shall be focused on minimizing the time to obtain necessary approvals in the Territory for the Licensed Product.

- 9 -

C. FRESENIUS shall use commercially reasonable means to deliver to NABI, within [*****] of the Effective Date, all the clinical data for ATG, and the clinical data for Global ATG that is relevant to NABI’s planned conduct of clinical studies and BLA submission to the US FDA and which, in either case, is in the possession or control of FRESENIUS (including the CRF and other pertinent files) together with such documents as may be necessary to reference any filing with the US FDA for approval of the Licensed Product as the same may exist on the Effective Date.

D. In the event of a disagreement between the parties with respect to the strategy or time table in the Territory, the NABI Scheduled Obligations, the FRESENIUS Scheduled Obligations or any supplemental agreement to be entered into regarding safety or quality, the parties shall first meet and confer and endeavor in good faith to resolve the disagreement. If the disagreement persists, the parties will elevate the discussion to the Steering Committee. If the Steering Committee cannot resolve the issue, the parties will elevate the discussion to their respective CEOs for resolution. If the disagreement cannot be resolved by the CEOs, NABI shall have the final deciding vote with respect thereto (except with respect to the Facility upgrade which is governed by Section 4.1(A), the content and date for delivery of the toxicology package which are governed by Section 4.1(B)(y) , any supplemental agreement to be entered into regarding quality, and the other FRESENIUS Scheduled Obligations).

E. NABI shall at all times during the development phase as well as during the commercialization process, give prompt written notice to FRESENIUS of any substantive, content-driven notices or communications (other than purely scheduling or administrative items) between NABI and regulatory agencies regarding the Licensed Product. Prior to any substantive, content-driven communications with the US FDA, the FRESENIUS members of the project team shall have reasonable notice of, and the opportunity to discuss, all matters in accordance with Section 4.6. NABI shall allow FRESENIUS the right, at its sole cost, to participate along with NABI in any meetings or conference calls with the US FDA and all other regulatory agencies, provided that NABI will have the final say in all matters to be communicated to the US FDA with respect to the Licensed Product.

F. FRESENIUS shall at all times during the development phase as well as during the commercialization process, give prompt written notice to NABI of any substantive, content-driven notices or communications between FRESENIUS and regulatory agencies regarding the safety and efficacy of Global ATG or the Licensed Product or the US FDA qualification of the Facility.

4.2. Clinical Development

A. NABI shall be responsible for the clinical development of the Licensed Product in the Territory and shall satisfy all costs associated with the conduct of clinical studies in connection with such development (except as set forth in Section 5.1).

- 10 -

B. After obtaining the first market authorization within the Territory for the Licensed Product, the parties will discuss the further conduct of global clinical studies to increase the utilization of the Licensed Product, both within and outside the Territory. Such collaboration may include sharing the design of future clinical studies to maximize global product usage, and sharing in the costs to undertake such studies.

C. Subject to compliance with any bona fide third party restrictions, each party will cooperate to make available and grant the other party the right to use, free of charge, such party’s data arising out of its clinical and non-clinical development of ATG or Global ATG, as the case may be, in its respective geographic areas of operation for the purpose of advancing the development and commercialization of the Licensed Product with respect to all indications..

D. The parties shall grant to each other such rights of reference to, and the right to re-submit, any regulatory approvals and dossiers held by them as are reasonably necessary or useful to assist the parties in obtaining regulatory approvals with respect to the Licensed Product in their respective geographic areas of operation.

4.3. Non-clinical, Including Toxicology, Pharmacology (Animal Data), CMC and Process Development

FRESENIUS has worldwide responsibility for the non-clinical development (including toxicology and pharmacology (animal data)), CMC and process development for the Licensed Product. FRESENIUS will provide all non-clinical (including toxicology and pharmacology (animal data)), CMC and process development information under the control of FRESENIUS as necessary for NABI to obtain and maintain regulatory approval of the Licensed Product in the Territory. The time table for the delivery of such information to NABI shall be as set forth in Section 4.1(C) and the FRESENIUS Scheduled Obligations. The parties agree to work together in good faith to attempt to increase the expiration dating for the Licensed Product. In the event that the parties are successful in extending the shelf life of the Licensed Product, the first three months of such extended period shall be for the benefit of NABI and the excess of such extended period (beyond the first three months) shall be split 2/3rds for the benefit of NABI and the balance shall be for the benefit of FRESENIUS.

4.4. Regulatory Approval of Licensed Product and Compliance

A. NABI will have responsibility for obtaining and maintaining regulatory approvals by the authorities in the Territory.

B. NABI shall hold and own any regulatory filings pertaining to Licensed Product in the Territory. NABI is not entitled to transfer any regulatory filings pertaining to Licensed Products in the Territory to third parties except as otherwise provided in this Agreement.

C. NABI shall be responsible for the conduct of regulatory product actions (including field corrections and recalls) and adverse event reporting in the Territory. NABI shall consult with FRESENIUS in advance and keep FRESENIUS

- 16 -

7.2. Invoices

With each Delivery of Licensed Product, FRESENIUS will send an invoice to NABI. The price stated to be payable on each invoice in accordance with this Agreement will be paid within sixty (60) days of issuance.

7.3. Transfer Price for Commercial Supplies

A. Upon each Delivery of Licensed Product, FRESENIUS shall issue to NABI a provisional invoice. In the first and second calendar quarters in which Licensed Products are Delivered by FRESENIUS to NABI for commercial sale, such provisional invoice shall be based on a fixed price of [*****]. Commencing with the third (3^rd) calendar quarter in which Licensed Products are Delivered by FRESENIUS to NABI for commercial sale and in each quarter thereafter (each, a “Delivery Quarter”), FRESENIUS shall issue to NABI a provisional invoice for each [*****] vial of Licensed Product Delivered during the Delivery Quarter in an amount equal to the higher of (i) [*****] and (ii) the amount per [*****] vial that was determined to be payable in respect of Deliveries made to by NABI during the second calendar quarter preceding the Delivery Quarter (the “Measurement Quarter”) based on the calculation of the final Transfer Price payable in respect of the Measurement Quarter pursuant to Section 7.3(C).

B. Within fifteen (15) Business Days after the end of each calendar quarter in which there are Net Retail Sales, NABI shall provide a certification (signed by its Chief Financial Officer or other appropriate authorized officer) as to NABI’s Net Retail Sales of Licensed Product through the last day of the quarter just ended together with a reconciliation of the provisional invoice prices issued for such quarter and the final Transfer Price calculated in accordance with Section 7.3(C) and (D) below (a “Transfer Certificate”) and all information necessary to audit such certificate on the basis of the specific orders, batch numbers and other identifying information and quantity. Except as otherwise provided herein, all calculations shall be made on the basis of generally accepted accounting principles as applicable in the United States and the particular accounting policies and principles applied by NABI in the preparation of its audited financial statements. Any deficiency (or surplus) in payment of the Transfer Price, after giving effect to the minimum monthly payments made pursuant to Section 7.4 below, shall be paid by the applicable party within ten (10) days after the date of the Transfer Price Certificate, provided, however, that the Transfer Price for Licensed Product covered by an invoice that is not yet due need not be paid until its applicable due date as provided in Section 7.2 above.

C. Except where a minimum final Transfer Price of [*****] shall be payable pursuant to Section 7.3(D) below, the final transfer price (the “Transfer Price”) payable in respect of Licensed Product Delivered to NABI in a Delivery Quarter (upon calculation thereof on the basis of data furnished by NABI or as may be determined on the basis of an audit) shall equal the percentage of NABI’s Cumulative Annual Retail Sales for such Delivery Quarter in accordance with the table set forth below:

- 17 -


NABI’s Cumulative Annual Net Retail Sales in US$				Percentage of Net Retail Sales
up to [*****]				[*****]%

next [***] above [***]				[*****]%

next [***] above [***]				[*****]%

next [***] above [***]				[*****]%

portion above [*****]				[*****]%

D. Notwithstanding anything to the contrary in this Agreement, the final Transfer Price payable for Deliveries during a Delivery Quarter shall not be less than [*****]. In addition if NABI’s Average Quarterly Commercial Price for a Delivery Quarter was [*****], or higher, and the Transfer Price payable under Section 7.3(C) would be less than [*****], then notwithstanding Section 7.3(C) above, the final Transfer Price payable for Deliveries during such Delivery Quarter shall be [*****].

E. For the avoidance of doubt, Schedule B hereto sets forth several illustrations of the operation of this Section 7.3.

F. If NABI’s Average Quarterly Commercial Price is less than [*****] for more than four (4) consecutive calendar quarters, each of FRESENIUS and NABI shall have the rights set forth in Section 11.2(A)(ii) below.

G. In the event that the parties determine the need for a change in the volume of each vial, for example, to accommodate more or less extensive dosage requirements for certain indications, the price payable for certain clinical supplies of Licensed Product described in Section 5.1, the minimum, both provisional and final, Transfer Prices set forth in Sections 7.3(A) and 7.3(D) and above and the amount of NABI’s Average Quarterly Commercial price set forth in Section 7.3(F) above will be re-determined by extrapolation of the price difference between the larger or smaller dosage, and such revised amounts will apply with respect to the larger or smaller dosages.

7.4. Minimum Monthly payment

Commencing as of the first day of the first month after the US FDA grants marketing approval for the Licensed Product, as long as FRESENIUS is not in default of its obligation to supply Licensed Products as provided herein, NABI shall pay to FRESENIUS a minimum monthly payment (payable on the first (1^st) day of each month) equal to: (i) in months 1 through 12 after the US FDA grants marketing approval, the sum of [*****]; and (ii) in month 13 and each month thereafter during the Term, the sum of [*****]. This minimum monthly payment will be creditable, dollar for dollar, against each provisional and final invoice for the Transfer Price that FRESENIUS will issue to NABI during each calendar year in accordance with Section

- 18 -

7.3. For the sake of clarity, the parties agree that the portion of the sum of the 12 minimum monthly payments made in a particular calendar year (or a portion thereof) which is unrecouped in respect of invoices issued during such calendar year, or portion thereof, (including those invoices that are not payable until the next calendar year) will not carry over to the invoices issued in future calendar years. As an example, minimum monthly payment installments made during the months of January through December of 2009 will be allowed as a credit against the Transfer Price payable in respect of the invoices issued in such months (including those that are not payable until 2010), but any excess of the minimum monthly installments made in 2009 which is not applied with respect to invoices issued in calendar year 2009 (including those that are payable in 2010) will not be available to be carried over to the invoices issued in year 2010. FRESENIUS’ sole remedy for NABI’s failure to pay any installment of the minimum monthly payment shall be to terminate this Agreement as provided in Section 11.2(A)(i), provided, however, that (i) if the remedy of termination is not exercised within six (6) months of any failure to pay any monthly installment, the breach for failure to pay such installment will be automatically waived; (ii) if the remedy of termination is exercised within six (6) months of any failure to pay any monthly installment, then FRESENIUS shall remain entitled to receive payment of all unpaid installments which at the date of termination are not more than six (6) months past due, and (iii) as contemplated in Section 11.2(D), termination under this Section 7.4 shall be without prejudice to FRESENIUS’ right to seek damages and any and all remedies at law or equity in respect of the breach of any other provision of this Agreement by NABI which has not been cured prior to the date of termination.

7.5. Recalculation due to currency rate changes

A. The minimum Transfer Prices (referred to in Sections 7.3(A) through 7.3(D)), the Transfer Price, the minimum monthly payment due pursuant to Section 7.4, and the price payable for certain clinical supplies of Licensed Product described in Section 5.1 required to be paid under this Agreement shall be subject to adjustment if the average annual exchange rate for changing U.S. Dollars into Euros fluctuates more than fifteen percent (15%) in any calendar year from the U.S. Dollar to Euro rate of US $1.00 = € 0.833.

B. In such case, the parties shall negotiate in good faith an upward or downward adjustment to the minimum Transfer Prices (referred to in Sections 7.3(A) through 7.3(D)), the Transfer Price, the minimum monthly payment due pursuant to Section 7.4, and the price payable for certain clinical supplies of Licensed Product described in Section 5.1 to be paid under this Agreement as called for by paragraph (A) above, effective at the end of such calendar year. If the parties are unable to reach an agreement within one month after beginning any such adjustment negotiations, the issue shall be submitted to the Steering Committee. If the adjustment is referred to the Steering Committee and it is unable to reach a resolution within one month after written notice from one of the parties to the Steering Committee to consider the issue, then the parties will refer the issue to their respective CEOs for resolution within fifteen (15) days after written notice to consider the issue. If the issue cannot be resolved by the CEOs, then either party may refer the issue to binding arbitration according to Section 14.1. Any new price calculated by reason of the foregoing shall be effective on the first day of January following the year in which the US Dollar to Euro rate fluctuated by more than fifteen percent (15%) and appropriate adjustment shall be made on the basis of such rate.

(i) A person entitled to indemnification under this Section 10 (an “Indemnified Party”) shall give prompt written notification to the person from whom indemnification is sought (the “Indemnifying Party”) of the commencement of any action, suit or proceeding relating to a third-party claim (a “Third Party Claim”) for which indemnification may be sought or, if earlier, upon the assertion in writing of any such claim by a third party; provided, however, that the failure so to notify the Indemnifying Party promptly or at all shall not relieve the Indemnifying Party of any liability or obligation it may have to the Indemnified Party hereunder except to the extent of actual prejudice caused by such failure. Such written notification shall include a description in reasonable detail (to the extent known by the Indemnified Party) of the facts constituting the basis for such Third Party Claim and the amount of the Damages claimed. Within twenty-five (25) days after delivery of such written notification, the Indemnifying Party may, by written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party. Notwithstanding the foregoing, the Indemnifying Party may not assume the defense of any Third Party Claim for equitable or other non-monetary relief that would materially affect the ongoing operations of the business of the Indemnified Party.

(ii) The party not controlling such defense may participate therein at its own expense; provided that if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnified Party may assume or retain control of such action, suit, proceeding or claim and the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith shall be considered “Damages” for the purposes of this Agreement; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one counsel for all Indemnified Parties. The party controlling such defense shall keep the other party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other party with respect thereto.

- 25 -

(iii) The Indemnified Party shall not agree to any settlement of any Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The Indemnifying Party shall not agree to any settlement of any Third Party Claim that does not include a complete release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed.

10.4. PROCEDURE FOR OTHER CLAIMS.

An Indemnified Party wishing to assert a non-Third Party claim for indemnification under this Section 10 shall deliver to the Indemnifying Party a written notice (a “Claim Notice”) which contains (i) a description and the amount (the “Claimed Amount”) of any Damages incurred by the Indemnified Party, (ii) a statement that the Indemnified Party is entitled to indemnification under this Section 10 and a reasonable explanation of the basis therefor, and (iii) a demand for payment in the amount of such Claimed Amount. Within twenty-five (25) days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a written response in which the Indemnifying Party shall: (x) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case such response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer), (y) agree that the Indemnified Party is entitled to receive part, but not all, of the Claimed Amount (the “Agreed Amount”) (in which case such response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer ), or (z) contest that the Indemnified Party is entitled to receive any of the Claimed Amount. If the Indemnifying Party in such response contests the payment of all or part of the Claimed Amount, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve such dispute. If such dispute is not resolved within sixty (60) days following the delivery by the Indemnifying Party of such response, the Indemnifying Party and the Indemnified Party shall each have the right to submit such dispute to arbitration in accordance with the provisions of Section 14.1.

10.5. PRODUCT LIABILITY INSURANCE
