          MANAGEMENT
            OF THE COLLABORATION

           

          2.1           Steering
            Committee.

           

          (a)           Establishment.  The
            Parties hereby establish a Steering Committee consisting of six (6) members,
            three (3) of whom shall be Par designees and three (3) of whom shall
            be Immtech
            designees.  Each of the Steering Committee members shall have
            appropriate expertise to oversee the Parties’ performance of this
            Agreement.  The initial Steering Committee members shall be designated
            by each Party within one week after the Effective Date.  Each Party
            shall have the right at any time and from time to time to designate a
            replacement, on a permanent or temporary basis, for any or all of its
            previously-designated members of the Steering Committee.  At the
            beginning of each calendar year during the Term, each Party shall appoint
            one of
            its designees to serve as a Co-Chair of the Steering Committee.  The
            initial Co-Chairs shall be designated by each Party within one week after
            the
            Effective Date.

           

          (b)           Meetings
            and Procedures.

           

          (i)             The
            Steering Committee shall meet at least once per calendar quarter, and
            more
            frequently at the request of either Party or as required to resolve disputes,
            disagreements or deadlocks, on such dates, and at such places and times,
            as the
            Parties shall agree; provided, however, that the Parties shall use
            their Commercially Reasonable Efforts to cause the first meeting of the
            Steering
            Committee to occur within thirty (30) days after the Effective
            Date.  The two Co-Chairs shall cooperate to send a notice and agenda
            for each meeting of the Steering Committee to all members of the Steering
            Committee reasonably in advance of the meeting.  The location of
            regularly-scheduled Steering Committee meetings shall alternate between
            the
            offices of the Parties, unless otherwise agreed.  The members of the
            Steering Committee also may convene or be polled or consulted from time
            to time
            by means of telephone conference, video conference, electronic mail or
            correspondence and the like, as deemed necessary or appropriate by the
            Co-Chairs.  The Party hosting any Steering Committee meeting shall
            appoint one person (who need not be a member of the Steering Committee)
            to
            attend the meeting and record the minutes of the meeting in
            writing.  Such minutes shall be circulated to the members of the
            Steering Committee promptly following the meeting for review and
            comment.

            written consent of both Parties, with each Party having, collectively

            necessary final determination with respect to decisions related to the

            have
            the right to make any necessary final determination with respect to decisions
            related to the Commercialization of the Product in the Territory (e.g.,
            marketing programs and pricing strategies and designation of product
            labels);
            and (iii) any other matters shall be subject to resolution by the chief
            executive officers of the Parties pursuant to Section 13.5.

            Committee each of whom shall have expertise and experience in the areas
            of
            pharmaceutical development and manufacturing.  Either Party may
            replace any or all of its designees on the Development Committee at any
            time
            upon written notice to the other Party, and any member of the Development
            Committee may designate a suitable proxy to perform the functions of
            that member
            at any time.  In addition, the Development Committee shall seek to act
            with the unanimous consent of all members of the Development
            Committee.  In the event that the Development Committee members do not
            reach consensus with respect to a matter that is within the purview of
            the
            Development Committee, the Development Committee designees of each Party
            shall
            collectively have one vote for purposes of decision-making hereunder
            with
            respect to such matters, with decisions made by unanimous vote of both
            Parties.  If the votes of the Development Committee are split on any
            matter, such matter shall be referred to the Steering Committee for
            decision.

            reviewing and approving medical claims and marketing materials to be
            used by any
            Party in connection with the Product to ensure that the claims made by
            a Party
            do not diminish the value of the Product to the other party and (ii)
            coordinating the activities of the Parties related to the
            Commercialization.  Each Party shall appoint two  designees
            to the Commercialization Committee, each of whom shall have expertise
            and
            experience in the areas of marketing, promotion, advertising and
            sales.  Either Party may replace any or all of its designees on the
            Commercialization Committee at any time upon written notice to the other
            Party,
            and any member of the Commercialization Committee may designate a suitable
            proxy
            to perform the functions of that member at any time.  In addition, the
            Commercialization Committee shall seek to act with the unanimous consent
            of its
            members.  In the event that all of the Commercialization Committee
            members do not reach consensus with respect to a matter that is within
            the
            purview of the Commercialization Committee, the Commercialization Committee
            designees of each Party shall collectively have one vote for purposes
            of
            decision-making hereunder with respect to such matters, with decisions
            made by
            unanimous vote of both Parties.  If the votes of the Commercialization
            Committee are split on any matter, such matter shall be referred to the
            Steering
            Committee for decision. 

           

          2.4           Expenses.  Each
            Party shall be responsible for all travel and related costs and expenses
            for its
            members and approved invitees to attend meetings of, and otherwise participate
            on, the Steering Committee, Development Committee and/or Commercialization
            Committee.

provided, however, that Immtech shall include Par in such efforts
            in a consultative capacity.  The Development Program shall be
            conducted at and coordinated from the facilities of Immtech.  Immtech
            shall keep Par apprised of the status of the Development Program through

            is
            experimental in nature; and (b) Immtech does not guaranty that the Development
            Program will be successful or that Regulatory Approval will be obtained

            Party and
            provide a copy of any written communication as soon as reasonably
            practicable.

           

          3.4           Development
            Program Funding.  Immtech shall be solely responsible for
            payment of all Development Costs incurred prior to Regulatory
            Approval.  If Par determines to pursue any clinical development in
            respect of the Product following Regulatory Approval, including any development
            for PCP prophylaxis or any other PCP indication, the development costs
            in
            respect thereof shall be the responsibility of Par unless the Parties
            otherwise
            agree.

           

          3.5           Development
            Program Reporting.  Immtech shall (a) provide Par at
            regularly scheduled meetings of the Development Committee with summary
            updates
            regarding the progress of the Development Program and Regulatory Approval
            process, (b) advise Par of any unforeseen material problems or delays
            encountered since the date of its last report in connection with the
            Development
            Program, and (c) provide Par as soon as reasonably practicable with such
            other
            material information as Par may reasonably request in writing from time
            to time
            with respect to the status of the Development Program.

           

          3.6           Post
            Regulatory Approval. Immtech will be
            responsible for conducting any development programs for the Product required
            by
            the FDA following Regulatory Approval.  As mutually agreed by the
            Parties, Immtech will be responsible for conducting any development programs
            related to clinical trials for the Product.  

           

          3.7           Future
            Development Programs.  Immtech shall promptly notify Par
            of any additional development programs, including tests or clinical trials,
            in
            connection with the Product other than as contemplated by this
            Agreement.  If Immtech discovers new indications for pafuramidine at
            any time during the Term, Immtech shall promptly provide all information
            related
            to such new indications to the Development Committee.

                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

                to

                other information shall be automatically deemed to be within the

          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

          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.

            Milestone Payments.  Subject to the terms and conditions
            of this Agreement, upon the achievement of certain milestones, Par shall
            make

            transfer of immediately available funds as follows:[****]

            Milestones. In addition to the milestone
            payments set forth in Section 5.2(a), Par shall additionally be obligated
            as
            follows: 

           

          (i)           Par
            will pay to Immtech [****] in the calendar year in which aggregate Net
            Sales in
            the Territory initially equals or exceeds [****] (i.e., this payment is a
            one-time obligation).

            year,
            from the following schedule:

           

          (a)         A

            Territory;

           

          (iii)             The
            milestone payments set forth in this Section 5.2(b) are subject to the
            following
            disbursement limitations: (A) each such milestone payment is available
            to
            Immtech on a one-time basis; (B) if more than one milestone is reached
            in any
            given calendar year, then, subject to the following clause (C), each
            of such
            milestones shall be deemed to have been met, the highest milestone reached
            in
            such year shall be payable by Par in such year and Par will remain obligated
            to
            make payment(s) on the lower achieved milestone payment(s) in the immediately
            subsequent year(s); and (C) Par shall not be obligated to make more than
            one
            sales milestone payment as provided in this Section 5.2(b) in any calendar
            year;
provided, however, that the milestone payments in Section
            5.2(b)(i) and a single milestone payment in Section 5.2(b)(ii) can be
            paid by
            Par in the same calendar year.  

           

          (c)           Royalty
            Payment.  In addition to the milestone payments set forth
            above in Sections 5.2(a) and 5.2(b), following the Initial Commercial
            Sale of

            or Adjustment of Royalty.  The obligation of Par to pay
            Royalties to Immtech pursuant to Section 5.2(c) shall cease on the date
            on which

          (b)           Payments
            and Reports.  All amounts payable to Immtech under this
            Agreement shall be paid in U.S. Dollars.  The Royalty shall accrue at
            the time of sale of the Product to a Third Party.  Royalty obligations
            that accrue during a calendar quarter shall be paid within forty-five
            (45) days
            after the end of such calendar quarter, and other payments owing shall
            be made
            as specified herein.  Each payment of Royalties due to Immtech shall
            be accompanied by a report listing the gross invoiced sales of the Product
            sold
            during such period and the calculation of Net Sales based on such sales,
            including all other information necessary to determine the appropriate
            amount of
            such Royalty payments, and any additional information or reports required
            under
            this Agreement.

           

          (c)           Records
            and Audit.  For a period of three (3) years after the
            Royalty period to which the records relate, Par shall keep complete and
            accurate
            records pertaining to the sale or other disposition of the Product in
            sufficient
            detail to permit Immtech to confirm the accuracy of all payments due
            hereunder.  Immtech shall have the right to cause an independent,
            certified public accountant to audit such records to confirm the Net
            Sales and
            Royalty payments; provided, however, that such auditor shall not
            disclose Par’s Confidential Information to Immtech, except to the extent such
            disclosure is necessary to verify the amount of Royalties and other payments
            due
            under this Agreement.  Such audits may be exercised once a year,
            within three (3) years after the Royalty period to which such records
            relate,
            upon notice to Par and during normal business hours.  Any amounts
            shown to be owing by such audits shall be paid promptly.  Immtech
            shall bear the full cost of such audit unless such audit discloses a
            variance in
            the amounts paid by Par of more than five percent (5%) from the amount
            of
            Royalties and/or other payments actually owed for the period
            audited.  In such case, Par shall bear the full cost of such
            audit.  The terms of this Section 5.4(c) shall survive any termination
            or expiration of this Agreement for a period of three (3) years.

          selling
            the Product.  Par shall, at all times during the term of the
            Agreement, use efforts equal to those committed to products of similar
            size and
            expected value to seek to commercialize the Product in the
            Territory for those formulations and indications for which Par is
            commercializing the Product without Immtech.

           

          (b)           Distribution.  Immtech
            hereby appoints Par as the sole and exclusive distributor of the Product

            launch
            dates for the Product, (b) develop advertising and promotional materials

            other end users of the Product, (g) monitor inventory levels of the Product,
            (g)
            provide first line customer support and pharmacovigilance (and after
            such
            initial support, pharmacovigilance support shall be handled in accordance
            with

          (c)           Pricing.  Subject
            to the reasonable input of Immtech, Par shall have the sole right and
            responsibility to determine the prices for the Product and any discounts
            and

            Immtech
            in substantially the form attached hereto as Exhibit A; provided,
however, that, with respect to any quantities of Product Par
            distributes
            as samples to persons in the medical profession, Par shall acquire such
            quantities from Immtech at the Direct Cost.

          7.1           Treatment
            of Confidential Information.  Each Party agrees to retain
            in strict confidence and not to disclose, divulge or otherwise communicate
            to
            any other person or entity any Confidential Information of the other

            to, and
            in order to carry out, the terms and objectives of this Agreement, except
            that

            performance
            by the receiving Party of this Agreement and (b) will use the Confidential

            to use at least the same standard of care in complying with its confidentiality
            obligations hereunder as it uses to protect its own Confidential Information
            of

          Representatives.  Each
            Party warrants that each of its Representatives to whom any Confidential
            Information is revealed shall previously have been informed of the confidential
            nature of the Confidential Information and shall have agreed to maintain
            its
            confidentiality under terms no less restrictive than those set forth
            in this
            Article VII.  Without limiting the generality of any of the foregoing,
            the parties agree not to make any disclosure of Confidential Information
            that
            would be reasonably likely to impair the Parties’ ability to obtain U.S. or
            foreign patents on any patentable invention or discovery described or
            otherwise
            embodied in such Confidential Information.  The Confidential
            Information of each Party includes information from Third Parties disclosed
            by
            one Party to this Agreement to the other Party to this
            Agreement.

            from Restrictions.

           

          (a)           The
            provisions of Section 7.1 shall not apply to any Confidential Information
            disclosed hereunder to the extent that such Confidential Information
            is required
            to be disclosed by the receiving Party to defend or prosecute litigation
            or to
            comply with applicable laws or regulations, including filing an Information
            Disclosure Statement with the U.S. Patent and Trademark Office or any
            other
            patent office, or pursuant to an order of a court or regulatory agency,
            provided
            that the receiving Party shall provide prior written notice of such disclosure
            to the other Party and shall take actions as are reasonable and lawful
            to avoid
            and/or minimize the degree of such disclosure, including assisting the
            other
            Party in seeking a protective order or other means for preventing disclosure
            or
            use.  To the extent, if any, that a Party concludes in good faith that
            it is required by applicable laws or regulations to file or register
            this
            Agreement or a notification thereof with any governmental authority,
            including
            the U.S. Securities and Exchange Commission, such Party may do so, and
            the other
            Party shall cooperate in such filing or notification and shall execute
            all
            documents reasonably required in connection therewith.  In such
            situation, the filing Party shall request confidential treatment of sensitive
            provisions of the Agreement to the extent permitted by law.  The
            Parties shall promptly inform each other as to the activities or inquiries
            of
            any such governmental authority relating to this Agreement, and shall
            cooperate
            to respond to any request for further information therefrom.

           

          (b)           A
            Party may disclose this Agreement to a Third Party in connection with
            or in
            conjunction with a proposed merger, consolidation, sale of assets that
            include
            those related to this Agreement, an assignment of this Agreement or loan
            financing, raising of capital, or sale of securities, provided that the
            disclosing Party obtains an agreement for confidential treatment thereof,
            except
            in the case where after reasonable efforts such Party is unable to obtain
            such
            agreement.

           

          7.3           No
            Implied Rights.  Except as otherwise set
            forth in this Agreement, nothing herein shall be construed as giving
            either
            Party any right, title, interest in or ownership of the Confidential
            Information
            of the other Party.  For the purposes of this Agreement, specific
            information disclosed as part of Confidential Information shall not be
            deemed to
            be in the public domain or in the prior possession of the receiving Party
            merely
            because it is embraced by more general information in the public domain
            or by
            more general information in the prior possession of the receiving
            Party.

          8.2           Patent
            Prosecution and Maintenance.  The Parties shall cooperate
            in good faith to determine whether to seek or continue to seek or to
            maintain
            patent protection in the Territory with respect to any Immtech Patent
            Rights,
            Immtech Know-How and Program Developments Owned or Controlled by Immtech
            and
            related to the Product, and whether to file for, procure and maintain
            Patent
            Rights in the Territory with respect to any Immtech Patent Rights and
            Program
            Developments Owned or Controlled by Immtech and related to the
            Product.  In connection with obtaining Patent claims that cover the
            making, using or selling of the Product, Immtech shall promptly provide
            to Par
            copies of all correspondence to and from the U.S. Patent and Trademark
            Office
            and shall promptly forward to Par copies of any non-confidential external
            publications or public presentations by Immtech relating to the Product
            for
            which Immtech has not received or applied for Patent Rights, as well
            as demands,
            notices and summonses related thereto.  Additionally, Immtech shall
            accommodate all reasonable suggestions of Par and its counsel in connection
            with
            obtaining such Patent claims.  The expenses of any such protection of
            Immtech Patent Rights, Immtech Know-How and Program Developments, including
            the
            filing of any Patent term extensions and maintenance of Patents, shall
            be borne
            by Immtech.  Immtech will timely file for any Patent term
            extensions.

          8.3           Infringement.  

           

          (a)           Par
            and Immtech shall inform each other promptly in writing of any alleged
            or
            suspected infringement by a Third Party of any of Immtech Technology
            or Program
            Developments related to the Product, and of any available evidence
            thereof.

           

          (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.

           

          (e)           Within
            ten (10) days of being notified of alleged or suspected Product Infringement,
            Par shall either (i) institute a suit for Product Infringement pursuant
            to
            Section 8.3(c) or (ii) notify Immtech that (A) it has a legally relevant
            belief
            that it is in the Parties’ interest to not institute such suit within such time
            and (B) it intends to institute such a suit in the future.  If Immtech
            agrees with Par’s assessment and intent to bring such suit in the future, Par
            shall have the right to institute such suit in accordance with Section
            8.3(c).  If Immtech provides Par with written notice within five (5)
            days of receipt of the notice from Par in accordance with

                    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.

          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

          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

            trials,
              investigations and findings relating to the Product.
              Adverse Drug Events (ADEs) and Individual Case Safety Reports (ICSRs)
              may
              originate from any source, such as healthcare professionals, regulatory
              authorities, literature, consumers, patients, lawyers, clinical studies
              (including post-marketing surveillance and epidemiological studies),
              non-interventional studies, patient support programs, registries, internet,
              preclinical studies (e.g. toxicological studies), etc. Each Party shall
              use
              every effort to ensure that all ADE/ICSR or pregnancy reports meet
              the minimum
              regulatory criteria for a valid safety report.  Par shall forward all
              ADEs/ISCRs received for the Product to Immtech within five calendar
              days of
              receipt. Format for event reporting from Par to Immtech shall be a
              copy or
              facsimile of the source documentation. All event information will be
              transmitted
              via fax or secure email. The regulatory reporting time clock for submitting
              ADE/ICSR and pregnancy reports to Immtech is considered to start on
              the date
              when any individual within Par is first notified of a case report that
              fulfills
              the minimum criteria for a case report.

          

           

          9.2           Reporting.  With
            regards to the Product, Immtech is responsible for preparing and submitting
            aggregate and individual case regulatory safety reports within the Territory
            as
            required by regulatory authorities. Immtech shall also hold and maintain
            reports
            of all adverse events and adverse drug reactions, both serious and non-serious,
            and reports of pregnancies in a database for the Product for preparing
            and
            submitting aggregate and single case reports to the FDA for the
            Product.

           

          9.3           Literature
            Reports.  Immtech shall be responsible for screening
            published scientific and medical literature for ADEs/ICSRs. Par shall
            be
            responsible for notifying Immtech of any relevant ADEs/ICSR that may
            come to its
            attention in Par Territory via local scientific or medical journals,
            or
            unpublished scientific or conference papers.  A copy of the article
            shall be provided at the same time as the report.

          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.

          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

    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.

      Information of the other Party.

     

    12.7           Surviving
      Rights.  The obligations and rights of the Parties under

      VII, IX, XI and XIII shall survive termination or expiration of this
      Agreement.  

     

    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.

    MISCELLANEOUS

     

    13.1           Entire
      Agreement; Modification.  This Agreement, together with
      the Schedules attached hereto and incorporated herein, constitutes the entire
      understanding and agreement of the Parties with respect to the subject matter
      hereof and cancels and supersedes any and all prior negotiations,
      correspondence, understandings and agreements, whether verbal or written,
      between the Parties with respect to the subject matter hereof.  No
      modification or amendment of any provision of this Agreement shall be valid
      or
      effective unless made in writing and signed by a duly authorized officer of
      each
      Party.

     

    13.2           Assignment.  This
      Agreement shall be binding upon and inure to the benefit of the Parties hereto
      and their permitted successors and assigns; provided, however,
      that neither Party shall assign any of its rights and obligations hereunder
      without the prior written consent of the other Party except to an Affiliate
      or
      as incident to the merger, consolidation, reorganization or acquisition of
      stock
      or assets affecting substantially all of the assets or actual voting control
      of
      the assigning Party.  Any assignment or attempted assignment by either
      Party in violation of the terms of this Section 13.2 shall be null and
      void.

     

    13.3           Performance
      by Affiliates.  The Parties recognize that each Party may
      perform some or all of its obligations under this Agreement through one (1)
      or
      more of its Affiliates; provided, however, that each Party shall
      remain responsible for and shall guarantee such performance by its Affiliates
      and shall cause its Affiliates to comply with the provisions of this
Agreement
      in connection with such performance.  Each Party hereby expressly
      waives any requirement that the other Party exhaust any right, power or remedy,
      or proceed against an Affiliate, for any obligation or performance hereunder
      prior to proceeding directly against such Party.

bonafide dispute as to certain matters may, from time

    In
      the
      event that the designated officers are not able to resolve the dispute within
      such thirty (30)-day period, or such other period of time as the parties may
      mutually agree to in writing, each party shall have the right to pursue any
      and
      all remedies available at law or in equity.

     

    13.7           Governing
      Law; Waiver of Jury Trial.   This Agreement shall be
      governed by, and construed in accordance with, the laws of the State of New
      York
      without reference to any rules of conflicts of laws.  The parties
      hereby consent to the exclusive jurisdiction of the Federal and State courts
      of
      New York and hereby waive any objection to venue or forum laid
      therein.  The parties hereby agree that service of process by
      certified mail, return receipt requested, shall constitute personal service
      for
      all purposes hereof.  The parties expressly reject the application of
      the United Nations Convention on Contracts for the International Sale of Goods
      and all implementing legislation thereunder.  EACH PARTY HEREBY WAIVES
      ITS RIGHT TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON, ARISING
      OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY,
      IN
      ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY
      AGAINST THE OTHER, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR
      OTHERWISE.  THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
      RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
      AGREEMENT.  

     

    13.8                      Force
      Majeure.  A party hereto shall be excused and shall not
      be held liable or responsible for failure or delay in fulfilling or performing
      any of its obligations under this Agreement  if such failure or delay
      is caused by acts of God, acts of the public enemy, fire, explosion, flood,
      drought, war, terrorists, riot, unavailability of raw material, sabotage,
      embargo, strikes or other labor disputes, intervention of governmental
      authority, or by any other event or circumstance of like or different character
      to the foregoing beyond the reasonable control and without the fault or
      negligence of the affected party (a “Force Majeure
      Event”).  Such excuse shall continue as long as the Force Majeure
      Event continues.  Upon cessation of such Force Majeure Event, such
      party shall promptly resume performance hereunder.  Each party agrees
      to give the other party prompt written notice of the occurrence of any Force
      Majeure Event, the nature thereof and the extent to which the affected party
      will be unable to perform its obligations hereunder.  Each party
      further agrees to use reasonable efforts to correct or otherwise address the
      Force Majeure Event as soon as practicable and to give the other party prompt
      written notice when it is again fully able to perform such
      obligations.

     

    13.9                      Independent
      Contractors.  In making and performing this Agreement,
      Par and Immtech act and shall act at all times as independent contractors and
      nothing contained in this Agreement
      shall be construed or implied to create an agency, partnership or employer
      and
      employee relationship between Immtech and Par.  At no time shall one
      Party make commitments or incur any charges or expenses for or in the name
      of
      the other Party.

     

    13.10                      Severability;
      Waiver.  If one (1) or more of the provisions of this
      Agreement are held by any court or authority having jurisdiction over this
      Agreement or either of the Parties to be invalid, illegal or unenforceable,
      such
      provision or provisions shall be validly reformed to as

        not
        be affected so long as the Parties are still able to realize the principal
        benefits bargained for in this Agreement.  The failure of a Party to
        insist upon strict performance of any provision of this Agreement or to exercise
        any right arising out of this Agreement shall neither impair that provision
        or
        right nor constitute a waiver of that provision or right, in whole or in
        part,
        in that instance or in any other instance.  Any waiver by a Party of a
        particular provision or right shall be in writing, shall be as to a particular
        matter and, if applicable, for a particular period of time and shall be signed
        by such Party.

    

     

    13.11                      Further
      Actions.  Each Party agrees to execute, acknowledge and
      deliver such further instruments, and to do all such other acts, as may be
      necessary or appropriate in order to carry out the purposes and intent of this
      Agreement.

     

    13.12                      Cumulative
      Rights.  The rights, powers and remedies hereunder shall
      be in addition to, and not in limitation of, all rights, powers and remedies
      provided at law or in equity, or under any other agreement between the
      Parties.  All of such rights, powers and remedies shall be cumulative,
      and may be exercised successively or cumulatively.

     

    13.13
                           Counterparts.  This
      Agreement may be executed in two (2) or more counterparts, each of which shall
      be an original and all of which shall constitute together the same
      document.  Counterparts may be signed and delivered by facsimile, each
      of which shall be binding when sent.

    Immtech
      warrants that neither it, nor its vendors, will engage in any act which causes

      will not be adulterated, within the meaning of the federal Food, Drug and

    Immtech
      will take all steps reasonably necessary to ensure that it has contracted with
      Third Party manufacturers with the facilities, equipment, instrumentation,

      in connection with Immtech’s supply of Product.  Immtech shall provide
      a COA for each lot of Product supplied hereunder at the time of

      provided, however, that other than with respect to defects or
      other non-compliance plainly observable from a visual inspection, any acceptance
      or deemed acceptance shall not adversely affect or otherwise diminish Par’s
      rights to receive shipments of the Product in compliance with the requirements
      of Section 4,1, 4.3(a), 4.3(b) or 5.1.  In the event of any

      laboratory to review records, test data and to perform the tests and/or analyses
      set forth in the Specifications on samples of the alleged Defective
      Product.  The independent laboratory’s results shall be final and
      binding.  Unless otherwise agreed to by the Parties in writing, the
