acceptable electronic media, copies or reproductions of all Immtech Know-How, not previously disclosed to Par, reasonably necessary in order to enable Par to exploit its rights granted under Section 4.1.  In addition, during the Term of this Agreement, Immtech shall promptly disclose to Par in writing, or via mutually acceptable electronic media, on an ongoing basis, copies or reproductions of all new Immtech Know-How that is reasonably necessary to market, sell or have sold the Product.  Such Immtech Know-How and other information shall be automatically deemed to be within the scope of the licenses granted herein without payment of any additional compensation.
 
4.3           Agreement Not to Genericize. Par recognizes and acknowledges the value of the Immtech Know-How disclosed under this Agreement and the Immtech Technology to which Par is granted a license under this Agreement.  Accordingly, Par agrees that it will not file any ANDAs related to the Product or any product containing pafuramidine, and that it will not attempt to copy or design around, the Product or any product containing pafuramidine without express written agreement from Immtech.  Par and Immtech will negotiate terms in good faith whereby Par would become the exclusive authorized generic distributor of the Product.
 
4.4           New Indication Right of First Offer .  
 
(a)           Right of First Offer.  The Parties acknowledge that Immtech is currently pursuing new indications for pafuramidine for the treatment and prophylaxis of malaria.  If, following the Effective Date, Immtech determines that pafuramidine can be used for the treatment and/or prophylaxis of malaria, Immtech shall, prior to instituting any Phase III development program in respect thereof, provide Par with a one time written notice of information reasonably available to Immtech, including an estimate of the cost for developing and obtaining regulatory approval therefor, that is reasonably required by Par to determine whether or not to enter into an agreement with Immtech with respect to such additional indication.  The delivery of such notice shall automatically grant to Par a one time exclusive option (the “Option”) to enter into an agreement with Immtech for a license to permit Par and its Affiliates to market, sell and have sold pafuramidine for such additional indication (the “New License Agreement”).  Par shall have twenty-five (25) days from receipt of such notice to (i) exercise the Option by sending written notice to Immtech of its intent thereof or (ii) reject the Option, in either case at which time the following shall occur:
 
(i)             If Par exercises the Option, the Parties shall have ninety (90) days from the date of exercise of the Option to negotiate in good faith a New Licensing Agreement with Immtech.  If, following such ninety (90)-day period, the parties have not executed the New Licensing Agreement, Immtech may, but shall not be obligated to, offer such license for pafuramidine to a Third Party; provided, however, that a New Licensing Agreement with any Third Party shall not provide such Third Party with the right to market, sell and have sold the Product in the Territory; and
 
(ii)           If Par rejects the Option, or does not inform Immtech of its intent to exercise the Option within the twenty-five (25)-day period, Immtech may, but shall not be

11

obligated to, offer such the New License Agreement to a Third Party; provided, however, that a New Licensing Agreement with any Third Party shall not provide such Third Party with the right to market, sell and have sold the Product in the Territory.
 
(b)           Future Indications.  Immtech shall use Commercially Reasonable Efforts to ensure that any new indications for pafuramidine shall be in materially different presentation from the Product (e.g., tradename, dosage form or reference listed drug).  If the presentation is not materially different, the Parties will negotiate in good faith a payment to Par to cover revenues that Par lost in commercial sales of the Product due to the new and immaterially different presentations.  Neither Immtech nor Par shall directly encourage use of the Product, nor use of the future indications of pafuramidine for treatment of conditions other than PCP, for any indication for which it does not have commercialization rights.  For purposes of clarification, the Parties agree that FDA may require that there be more than one indication on the same product label and such additional indication(s) shall not be deemed to affect the scope of the license granted herein in respect of the Product.

(b)           Subject to Sections 8.3(c), 8.3(d), and 8.3(e), Par may, at its sole option and expense, prosecute the infringement of any Immtech Technology or Program Developments related to the Product.
 
(c)           In the event that a Third Party infringes or constructively infringes Immtech Technology or Program Developments Owned or Controlled by Immtech relating to the Product in the Territory (a “Product Infringement”), then the Parties shall discuss whether or not to institute an infringement action with respect to such Product Infringement.  Subject to Section 8.3(d), Par shall have the right to institute such a suit and control the prosecution, settlement or compromise thereof.  At Immtech’s option, Immtech may request to be joined as a party in such Product Infringement action and Par shall execute all papers and perform such acts as may be reasonably required in respect thereof; provided, however, that Immtech’s joining of such action shall not affect Par’s control thereof.  Immtech shall, at the request of Par, provide reasonable cooperation and, to the extent possible, Immtech shall have its employees testify when requested and make available relevant records, papers, information, samples, specimens and the like regardless of whether Immtech has joined such suit.  Par shall bear all the costs of such a suit.
 
(d)           If a Third Party files an ANDA targeting both the Product and non-PCP indications for pafuramidine, Immtech shall have the right to institute a suit and control the prosecution, settlement or compromise thereof; provided, however, that Immtech shall not, without Par’s consent, take any action in the prosecution, settlement or compromise of such suit that would adversely affect Par’s rights hereunder or otherwise economically adversely affect the commercialization of the Product.  Immtech shall bear all the costs of such a suit.  At Par’s option, Par may request to be joined as a party in such litigation, provided, however, that Par’s joining of such action shall not affect Immtech’s control thereof.  Par shall, at the request of Immtech, provide reasonable cooperation and, to the extent possible, Par shall have its employees testify when requested and make available relevant records, papers, information, samples, specimens and the like regardless of whether Par has joined such suit.  Par shall have the right to select, at Par’s expense, separate counsel to participate in such suits on Par’s behalf.

**** Material omitted pursuant to a request for confidential treatment under Rule 24b-2 of the Exchange Act of 1934. Material filed separately with the Securities and Exchange Commission.
18

the foregoing clause (ii) that it does not reasonably agree with such assessment, then Par may immediately institute such suit and such suit shall be governed by Section 8.3(c); provided, however, that if Par determines not to institute such suit within five (5) days of receipt of such notice from Immtech, then Immtech may, at its option and expense, institute and litigate such Product Infringement.  In any such infringement suit Immtech may institute to enforce Immtech Technology or Program Developments Owned or Controlled by Immtech, Par shall, provide reasonable cooperation and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens and the like.  If Immtech initiates litigation of such Product Infringement pursuant to this Section 8.3(e), Par shall not make any admission to invalidity or unenforceability in respect thereof without the prior consent of Immtech.  Par may join Immtech as a party, and Immtech shall execute all papers and perform such acts as may be reasonably required, at the expense of Par.
 
(f)           Any Royalties, payments, damages, expenses, fees or other awards (collectively “Damages”), received by Par and/or Immtech as a result of an infringement suit, whether through judgment or settlement, shall first be used to reimburse each Party for its expenses associated with such infringement suit.  Thereafter, (i) if Par shall have been in control of such suit pursuant to Section 8.3(c), any remainder shall be shared by the Parties in accordance with the then-applicable Royalties provided in Section 5.2(c) (e.g., if the Net Sales have exceeded [****], Par shall be entitled to [****], and Immtech shall be entitled to [****], of the remainder), (ii) if Immtech shall have been in control of such suit pursuant to Section 8.3(e), Immtech shall be entitled to 100% of the remainder, unless Par  has chosen, after the initiation of such suit, to join as a party to such suit, in which case any remainder shall be shared by the Parties equally and (iii) if Immtech shall have been in control of such suit pursuant to Section 8.3(d), any remainder shall be shared according to each Party’s harm as indicated by the ratio of sales of the Product as compared to the sales of the products of the other Party or Parties.  The appropriate share of the Damages shall be paid to the other Party (or Parties), as applicable, as soon as practicable following receipt of the Damages.
 
(g)           In the event that a declaratory judgment action alleging invalidity or non-infringement of any Immtech Technology or Program Developments related to the Product shall be brought by a Third Party in the Territory against Par or against Immtech and Par, or a Citizen’s Petition shall have been filed with the USFDA, Par, at its option, shall have the right, within ten (10) days after commencement of such action or the filing of such Petition, as applicable, to take over the defense of the action at its own expense. Immtech will have the option of joining in such suit.  In the event the declaratory judgment action states a count specifically against Immtech, Immtech, at its option, shall have the right to direct and control litigation related to such count.  In the event that Par does not so elect to take over the defense of the action at its own expense, Immtech shall be free to proceed and solely control such defense.  To the extent that any Damages become payable to any Third Party as a result of such action, whether through judgment or settlement, the Parties shall bear such Damages according to each Party’s share of the liability in causing such Damages, and shall contribute such share as promptly as practicable.  Any Damages received by Immtech and/or Par as a result of such action, whether through judgment or settlement, shall first be used to reimburse each Party for its

19

expenses associated with such infringement suit not otherwise reimbursed, and then any remainder shall be shared by the Parties equally, with such share of the Damages to be paid to the other party, as applicable, as soon as practicable upon receipt of the Damages.
 
(h)           In the event that a Third Party institutes any suit against Par and/or Immtech for patent infringement related solely to the Product, the Party sued shall promptly notify the other Party in writing.  Immtech shall assume the defense of such suit at Immtech’s expense; provided, however, that if Par is also a defendant in such action and Par shall have reasonably concluded that there may be legal defenses available to it that are different from or additional to those available to Immtech, Par shall have the right to select, at Par’s expense, separate counsel to participate in such legal defenses on Par’s behalf.  Each Party shall, at the other's request, provide to the other Party reasonable assistance and cooperation with respect to any such suit.  To the extent that any Damages become payable to any Third Party whether as a result of judgment or through settlement of such suit, [****].
 
(i)           If either Party becomes aware of a patent or patent application that, when issued, might provide a basis for a Third Party argument that its valid rights are being infringed by the manufacture, use or sale of the Product hereunder, then such Party shall promptly inform the other Party of such patent or patent application, and the Parties shall cooperate with each other so that each Party can determine whether valid rights of a Third Party are likely to be infringed by the manufacture, use or sale of the Product hereunder.
 
(j)           Par shall have the sole and exclusive right to institute a Citizen’s Petition in order to protect the Immtech Patent Rights related to the Product and, to the extent it exercises its right in respect thereof, shall control all aspects of such Petition, including correspondence and/or negotiations with the FDA; provided, however, that Par shall include Immtech in such efforts in a consultative capacity.  Immtech shall maintain the sole and exclusive right to institute a Citizen’s Petition in order to protect the Immtech Patent Rights related to all other indications for pafuramidine
 
(k)           If either Party believes that a license from a Third Party is necessary to avoid infringement of patents of the Third Party, the Steering Committee shall: 1) determine whether or not to seek such a license, 2) appoint a negotiator to negotiate the terms of such a license, 3) determine whether or not to enter into such a license as negotiated by the negotiator, and 4) determine how the expenses of such a license shall be borne by the Parties.  If the Steering Committee cannot agree with regard to any responsibility set forth in the preceding sentence, such issue shall be determined accordance with Section 13.5.

ARTICLE XI
 
INDEMNIFICATION AND LIMITATION ON LIABILITY
 
11.1           Indemnification by Immtech.  Subject to Section 11.3, Immtech shall defend, indemnify and hold harmless each of Par and its directors, officers and employees and the successors and assigns of any of the foregoing (each a “Par Indemnitee”) from and against any and all liabilities, damages, settlements, penalties, fines, costs or expenses (including, without limitation, reasonable attorneys’ fees and other expenses of litigation) (collectively, “Liabilities”) arising, directly or indirectly, out of or in connection with Third Party claims, suits, actions, demands or judgments to the extent relating to or based on Immtech’s gross negligence, willful misconduct, or breach of its representations, warranties or obligations under this Agreement, except, in each case, to the extent Par has an obligation to indemnify Immtech under Section 11.2.
 
11.2           Indemnification by Par.  Subject to Section 11.3, Par shall defend, indemnify and hold harmless each of Immtech and its directors, officers and employees and the successors and assigns of any of the foregoing (each an “Immtech Indemnitee”) from and against any and all Liabilities arising, directly or indirectly, out of or in connection with Third Party claims, suits, actions, demands or judgments to the extent relating to or based upon Par’s gross negligence, willful misconduct, or breach of its representations, warranties or obligations under this Agreement, except, in each case, to the extent Immtech has an obligation to indemnify Par under Section 11.1.
 
11.3           Notice and Procedures.  If an Immtech Indemnitee or a Par Indemnitee (the “Indemnitee”) intends to claim indemnification under this Article XI, it shall promptly notify the other Party (the “Indemnitor”) in writing of any such alleged Liabilities.  The Indemnitor shall have the right to control the defense thereof with counsel of its choice, provided that such counsel is reasonably acceptable to Indemnitee; and, provided, further, that any Indemnitee shall have the right to retain its own counsel at its own expense, for any reason, including if representation of any Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party reasonably represented by such counsel in such proceeding.  The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Liabilities covered by this Article XI.  The obligations of this Section 11.3 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed unreasonably.  The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Section 11.3.  It is understood that only Immtech or Par may claim indemnity under this Article XI (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not directly claim indemnity hereunder.

ARTICLE XII
 
TERM AND TERMINATION
 
12.1           Term.  The term of this Agreement shall commence on the Effective Date and shall expire, unless earlier terminated as provided under Sections 12.2, 12.3 or 12.4, on the date on which any Royalty and other payment obligations of Par under this Agreement cease. 
 
12.2           Termination for Breach. If either party commits a material breach or material default in the performance or observance of any of its obligations under this Agreement, and such breach or default continues for a period of sixty (60) days after delivery by the other Party of written notice reasonably detailing such breach or default, then the non-breaching or non-defaulting Party shall have the right to terminate this Agreement, with immediate effect, by giving written notice to the breaching or defaulting Party.  The Parties shall retain all rights and remedies (at law or in equity) in respect of any breach hereof.

            12.3     
Termination for Bankruptcy
. This Agreement shall automatically terminate upon the initiation of any proceeding in bankruptcy, reorganization, dissolution, liquidation or arrangement for the appointment of a receiver or trustee to take possession of the assets of either Party or similar proceeding under the law for release of creditors by or against a party hereto or if a party hereto shall make a general assignment for the benefit of its creditors.  All licenses and rights to licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code (the “Code”), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code.  Par, as the licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Code, and upon commencement of a bankruptcy proceeding by or against Immtech under the Code, shall be entitled to a complete duplicate of, or complete access to (as Par deems appropriate), any such intellectual property and all embodiments of such intellectual property.  Such intellectual property and all embodiments thereof shall be promptly delivered to Par (a) upon any such commencement of a bankruptcy proceeding upon written request therefor by Par, unless Immtech elects to continue to perform all of its obligations under this Agreement or (b) if not delivered under (a) above, upon the rejection of this Agreement by or on behalf of Immtech upon written request therefor by Par, and each Party hereby acknowledges and agrees that the foregoing shall serve as its consent to such transfer of the

24

intellectual property and all embodiments thereof.  The foregoing provisions of this Section 12.3 are without prejudice to any rights Par may have arising under the Code or other applicable law.
 
12.5           Failure to Meet Development Milestones.  If either (i) Immtech fails to obtain Positive Phase III Clinical Trials in respect of the current Phase III Clinical Trials or (ii) the FDA rejects the NDA, then, Par shall have the right to immediately terminate this Agreement by providing a written notice of termination to Immtech.
 
12.6           Effect of Termination.  
 
(a)           Upon the termination of the Agreement by Par in accordance with Section 12.2, (i) Par and its Affiliates shall have a non-exclusive, royalty-free, fully-paid up, perpetual, worldwide license to the Immtech Technology to make, sell and have sold the Product in the Territory.
 
(b)           Upon the termination of the Agreement by Immtech in accordance with Section 12.2, (i) all rights and licenses granted to Par pursuant to this Agreement shall automatically and immediately terminate and Par immediately shall discontinue Commercialization of Product and all use of the Product trademarks (and any word or design confusingly similar thereto) and the Immtech Technology; and (ii) Par shall pay within thirty (30) days after such termination: (x) all accrued and unpaid amounts due to Immtech in accordance with the terms of this Agreement (including, if such termination shall occur following the grant of Regulatory Approval, any Sales Milestone payments that have been achieved but not yet paid by Par, any unpaid Royalties and transfer costs for Product manufactured pursuant to Par’s sales forecast but not yet delivered to Par, but only to the extent that Immtech is unable to sell such Product; (y) any other amounts that will become due to Immtech through or after the effective date of such termination in accordance with the terms hereof; and (z) if such termination shall occur prior to the grant of Regulatory Approval, the Development Milestones if and when they are achieved.  The remedies set forth in this Section 12.5(b) constitute Immtech’s sole and exclusive rights and remedies for a termination of the Agreement by Immtech in accordance with Section 12.2 at law or in equity in respect of thereof.
 
(c)           With the exception of any breach of Article VII of this Agreement, the parties agree that the provisions of this Section 12.5 are intended to limit the claims that the parties may have against each other in the circumstances described herein, and the liquidated damages provided herein bear a reasonable relationship to the anticipated harm that would be caused by the relevant breaches.  The parties further acknowledge and agree that, with the exception of any breach of Article VII of this Agreement, the amount of actual loss caused by such breaches of this Agreement as provided in Section 12.2 is difficult to estimate with precision and that the parties would not have a convenient and adequate alternative to liquidated damages hereunder.

12.8           Accrued Rights and Surviving Obligations.  The termination or expiration of this Agreement for any reason shall be without prejudice to any rights which shall have accrued to the benefit of either Party prior to such termination or expiration, including any damages arising from any breach hereunder.  Such termination or expiration shall not relieve either Party from obligations which are expressly indicated to survive termination or expiration of this Agreement.
