A.   STOCK PURCHASE AGREEMENT

     Abbott purchased the Shares pursuant to the terms of the Stock Purchase
Agreement.  In addition, the Stock Purchase Agreement permits the Issuer to
require Abbott to purchase additional shares of Common Stock  (the "Additional
Shares") if certain conditions are satisfied within a specified time period for

     Abbott acquired certain registration rights under the Stock Purchase
Agreement.  Subject to certain conditions, under Section 7.1, the Issuer must
notify the registered holder of the Shares and the Additional Shares
(collectively, the "Registrable Shares") of the registration of the Issuer's
securities (except a registration on Form S-4 or Form S-8) if the registration
form may be used for registration of the Registrable Shares.  The Issuer will
include in such registration all Registrable Shares with respect to which the
Issuer receives a written request to include in the registration within 21 days
of the notice.

     Subject to certain conditions, under Section 7.2, the registered holder of
the Registrable


                                  Page 4 of 6 pages


Shares may request at any time the registration of all or part of the
Registrable Shares on a Form S-3 or any similar short form, if available, so as
to permit the resale of the Shares.  The Stock Purchase Agreement also sets
forth the desire of the Issuer and Abbott to enter into a license agreement.

exclusive rights to manufacture, distribute, market and sell the Issuer's
injectable formulation of a compound for the treatment of systemic fungal

certain conditions.  Subject to certain conditions, Abbott is obligated to make
certain milestone, research and development funding, and royalty payments to the
Issuer.  Both the Issuer and Abbott undertake development and registration

To the knowledge of the Company, there are no facts which would reasonably serve as a basis for any claim that the Company does not have the right to use, free of any rights or claims of others, all Proprietary Rights in the development, manufacture, use, sale or other disposition of any or all products or services presently being used, furnished or sold in the conduct of the business of the Company as it has been and is now being conducted.

For all taxable years ending on or before December 31, 1997, the federal income tax liability of the Company and its Subsidiaries has been satisfied. The Company does not know of any proposed additional tax assessment against it for which adequate reserves have not been made on its balance sheet, and no material controversy in respect of additional federal or state income taxes due since such date is pending or, to the knowledge of the Company, threatened. The reserves for taxes on the books of the Company and each of its Subsidiaries are adequate in all material respects for all open years, and for its current fiscal period. 3.15 Use of Proceeds. The net proceeds from the sale of the Shares will be used to make an infusion of capital into the Company and for other corporate purposes. 3.16 Private Offering. The offering and sale of the Shares is and will be exempt from the registration requirements of the Securities Act and applicable state securities and blue sky laws.

The Company has not dealt with any broker or finder in connection with the transactions contemplated by this Agreement. The Company has not incurred, and shall not incur, directly or indirectly, any liability for any brokerage or finders' fees or agents' commissions or any similar charges in connection with this Agreement or any transaction contemplated hereby. 3.20 Full Disclosure.

There is no fact peculiar to the Company or the Subsidiaries which the Company has not disclosed to Abbott in writing which materially adversely affects nor, so far as the Company can now reasonably foresee, will materially adversely affect, the properties, business, profits or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole. 4.

(a) Whenever securities of the Company are to be registered under the Securities Act, other than pursuant to a registration statement on Form S-4 or Form S-8, and the registration form to be used may be used for the registration of the Registrable Shares (a "Piggyback Registration"), the Company will give prompt written notice to the Holder of its intention to effect such a registration and will include in such registration all Registrable Shares with respect to which the Company has received written requests for inclusion therein within 21 days after the Company's notice has been given. (b) If a Piggyback Registration relates to an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such offering will have an adverse effect on the offering (including the price at which the shares of Common Stock can be sold), the Company will include in such registration (i) first, the securities the Company proposes to sell for its own account, if any, and (ii) second, the Registrable Shares requested to be included in such registration and the securities requested to be included therein by any other holders of the Company's securities that have been granted piggyback registration rights prior to the date of this Agreement and which are applicable to such registration (all such Registrable Shares and other securities being collectively referred to as the "Secondary Shares") which in the opinion of such underwriters can be sold in such offering without creating such an adverse effect, allocated pro rata among the holders of such Secondary Shares on the basis of the number of Secondary Shares owned or deemed to be owned by such holders. 7.2 Demand Registration. (a) The Holder may request at any time the registration under the Securities Act of all or part of their Registrable Shares on Form S-3 or any similar short-form registration ("Short-Form Registration"), if available, so as to permit the resale thereof (a "Demand Registration"). The Holder will be entitled to request one Short-Form Registration for the Initial Shares and one Short-Form Registration for the Additional Shares. The Company will use its best efforts to make the Short-Form Registration available for the sale of Registrable Shares. If the Company is unable to make the Short-Form Registration available for the sale of the Registrable Shares within 90 days of the Holder's request, the Company shall cause the registration of the Registrable Shares on Form S-1 or S-2 or any similar long-form registration so as to permit the resale thereof. The Company shall keep such registration effective for at least 12 months or for such shorter period of time as is necessary for the distribution of the Registrable Shares thereunder to be completed in accordance with the Holder's intended method of distribution. (b) The Company may postpone for a reasonable period not to exceed 90 days the filing or the effectiveness of a registration statement for a Demand Registration if the Board of Directors determines reasonably and in good faith that such filing would require disclosure of a material fact that would have a material adverse effect on the Company or any plan by the Company or any of its Subsidiaries to engage in any acquisition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer or other material transaction. 7.3 Payment of Expenses. The Company will pay all registration expenses incurred in connection with the filing of the registration statements provided for in this Section 7, including all registration and filing fees, fees and expenses of compliance with federal, state and foreign securities laws, printing expenses, and fees and disbursements of counsel for the Company and its independent certified public accountants, underwriters, and other Persons retained by the Company, but excluding discounts and commission attributable to the Registrable Shares. The Holder will be responsible for the fees and expenses of its own counsel. 7.4 Additional Covenants of the Company. The Company agrees to use its reasonable best efforts to effect the registration of the Registrable Shares in accordance with the intended method of disposition thereof, and pursuant thereto, the Company agrees to: (a) prepare and file with the Commission such amendments and supplements to any registration statement filed pursuant hereof and the prospectus used in connection therewith as may be necessary to keep any such registration statement effective and available for resale of the Registrable Shares, and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by any such registration statement during such effective period in accordance with the intended methods of disposition by the Holder set forth in any such registration statement; (b) furnish to the Holder such number of copies of any registration statement filed pursuant to this Section 7, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as the Holder may reasonably request in order to facilitate the disposition of the Registrable Shares; (c) use its reasonable best efforts to register or qualify the Registrable Shares under such other securities or blue sky laws of such states of the United States as the Holder reasonably requests and of any and all other things which may be reasonably necessary or advisable to enable the Holder to consummate the disposition in such jurisdictions of the Registrable Shares owned by the Holder; provided, however, that the Company will not be required (A) to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 7.4, (B) to subject itself to taxation in any such jurisdiction or (C) to consent to general service of process in any such jurisdiction; (d) notify the Holder, at any time when a prospectus relating to any registration statement filed pursuant to this Section 7 is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading, and, at the request of the Holder, the Company will promptly prepare (and, when completed, give notice to each seller of Registrable Shares) a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Shares, such prospectus will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading; provided, however, that upon such notification by the Company, the Holder will not offer or sell Registrable Shares until the Company has notified the Holder that it has prepared a supplement or amendment to such prospectus and delivered copies of such supplement or amendment to each such seller; (e) in the event of the issuance of any stop order suspending the effectiveness or any registration statement filed pursuant to this Section 7, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Shares included in such registration statement for sale in any jurisdiction, the Company will use its reasonable best efforts promptly to obtain the withdrawal of such order; (f) in the event of any underwritten public offering in which Registrable Shares are to be offered and sold, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriters of such offering; and (g) use its best efforts to furnish, on the date that such Registrable Shares are delivered to the underwriters for sale in connection with a registration pursuant to this Section 7 and, in the case of the letter of the independent public accountants referred to in clause (ii) below, on the effective date of the registration statement, if such Registrable Shares are being sold through underwriters, or, if such Registrable Shares are not being sold through underwriters, on the effective date of the registration statement, (i) an opinion, dated such date, of counsel to the Company, in form and substance as is customarily given to the underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holder, and (ii) a letter, dated such date, from the Company's independent public accountants in form and substance as is customarily given to the underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holder. 7.5 Indemnification. (a) The Company agrees to indemnify the Holder, its officers and directors and each Person who controls the Holder (within the meaning of the Securities Act) against all losses, claims, damages and liabilities caused by any untrue or alleged untrue statement of material fact contained in any registration statement filed pursuant to this Section 7, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are (A) caused by or contained in any information furnished in writing to the Company by the Holder for use therein, (B) caused by the Holders' failure to deliver a copy of any such registration statement or prospectus or any amendments or supplements thereto after the Company has furnished the Holder with a sufficient number of companies of the same, or (C) caused by the Holder's sale of Registrable Shares in violation of the proviso to Section 7.4(d) hereof. (b) In connection with any registration statement filed pursuant to this Section 7, the Holder will furnish to the Company in writing such information and affidavits as the Company reasonable requests for use in connection with any registration statement or prospectus and will indemnify the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages and liabilities resulting from any untrue or alleged untrue statement of material fact contained in any such registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue or alleged untrue statement or omission or alleged omission is attributable to the information furnished by the Holder to the Company in writing expressly for use in such registration statement or prospectus or supplement thereto. (c) Any Person entitled to indemnification hereunder will (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (B) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. Subject to the foregoing terms and provisions of this Section 7.5(c), each indemnifying party hereunder will reimburse the person entitled to indemnification hereunder for all legal and other expenses reasonably incurred in connection with investigating and defending the action or claim for which such indemnified party seeks indemnification, as such expenses are incurred. (d) The indemnification provided for under this Section 7.5 will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities. 7.6 Limitations on Registration Rights. The Company shall not be obligated to register the Registrable Shares under the Securities Act (or deliver any notice with respect to a Piggyback Registration) if, in an opinion of counsel to the Company addressed to the Holder and the Company, reasonably satisfactory to the Holder and its counsel, the Registrable Shares may be offered and sold by the Holder without registration under the Securities Act pursuant to Rule 144(k) and that following such offer and sale, such Registrable Shares shall not be "restricted securities" within the meaning of the Securities Act and the rules thereunder. The Company shall defend and indemnify the Holder and its respective Affiliates, directors, officers, employees and shareholders and their respective successors and assigns against and hold each of them harmless from any and all losses, liabilities, claims, suits, proceedings, demands, judgments. damages, expenses and costs, including, without limitation, reasonable counsel fees, costs and expenses incurred in the investigation, defense or settlement of any claims, arising out of or relating the offer and sale of Registrable Shares in reliance on such opinion of counsel. 8. Indemnification. 8.1 Indemnification by the Company. (a) The Company agrees to defend and indemnify Abbott, its Subsidiaries and their respective Affiliates, directors, officers, employees and shareholders, and their respective successors and assigns (collectively, the "Abbott Indemnitees"), against and hold each of them harmless from any and all losses, liabilities, taxes, claims, suits, proceedings, demands, judgments. damages, expenses and costs, including, without limitation, reasonable counsel fees, costs and expenses incurred in the investigation, defense or settlement of any claims covered by this indemnity (in this Section 8 collectively, the "Indemnifiable Damages") which any such indemnified person may suffer or incur by reason of the inaccuracy or breach of any of the representations, warranties and covenants of the Company contained in this Agreement or any documents, certificate or agreement delivered pursuant hereto; provided, however, that the total indemnity shall not exceed the consideration received by the Company. Nothing herein shall limit in any way Abbott's remedies in the event of breach by the Company of any of its covenants or agreements hereunder which are not also a representation or warranty or for willful fraud or intentionally deceptive material misrepresentation or omission by the Company in connection herewith or with the transactions contemplated hereby. (b) No Abbott Indemnitee shall be entitled to recovery under the indemnities set forth herein unless and until the Indemnifiable Damages of all Abbott Indemnitees exceed $25,000, at which point such indemnity shall apply to all Indemnifiable Damages. (c) No claim for indemnification may be brought by an Abbott Indemnitee under this Section 8.1 more than 18 months (540 days) following the later of the Initial Closing Date or, if the Put Right has been exercised, the Additional Closing Date. 8.2 INDEMNIFICATION BY ABBOTT. After the Initial Closing Date, Abbott shall indemnify and hold harmless the Company and its officers and directors from and against: (a) any damage, deficiency, losses or costs incurred by the Company resulting from any material misrepresentation or breach of warranty or any non-fulfillment of any covenant or agreement on the part of Abbott under this Agreement; and (b) any claim, action, suit, proceeding, demand, judgment, assessment, cost and expense, including reasonable counsel fees, incident to the foregoing; provided that the total indemnity shall not exceed the purchase price paid by Abbott for the Shares pursuant to this Agreement. No claim for indemnification may be brought under this Section 8.2 more than 18 months (540 days) following the later of the Initial Closing Date or, if the Put Right has been exercised, the Additional Closing Date. 8.3 Indemnification Procedure. A party seeking indemnification (the "Indemnitee") shall use its commercially reasonable best efforts to minimize any liabilities, damages, deficiencies, claims, judgments, assessments, costs and expenses in respect of which indemnity may be sought under this Agreement. The Indemnitee shall give prompt written notice to the party from whom indemnification is sought (the "Indemnitor") of the assertion of a claim for indemnification; provided, however, that the Indemnitee's failure to notify the Indemnitor shall not excuse the Indemnitor's obligation to indemnify the Indemnitee except to the extent that such failure prejudices the Indemnitor's defense of any such claim. No such notice of assertion of a claim shall satisfy the requirements of this Section 8.3 unless it describes in reasonable detail and in good faith the facts and circumstances upon which the asserted claim for indemnification is based. If any action or proceeding shall be brought in connection with any liability or claim to be indemnified hereunder, the Indemnitee shall provide the Indemnitor 20 calendar days to decide whether to defend such liability or claim. During such period, the Indemnitee shall take all necessary steps to protect the interests of itself and the Indemnitor, including the filing of any necessary responsive pleadings, the seeking of emergency relief or other action necessary to maintain the status quo, subject to reimbursement from the Indemnitor of its expenses in doing so. The Indemnitor shall (with, if necessary, reservation of rights) defend such action or proceeding at its expense, using counsel selected by the insurance company insuring against any such claim and undertaking to defend such claim, or by other counsel selected by it and approved by the Indemnitee, which approval shall not be unreasonably withheld or delayed. The Indemnitor shall keep the Indemnitee fully apprised at all times of the status of the defense and shall consult with the Indemnitee prior to the settlement of any indemnified matter. The Indemnitee agrees to use its reasonable best efforts to cooperate with the Indemnitor in connection with its defense of indemnifiable claims. In the event the Indemnitee has a claim or claims against any third party growing out of or connected with the indemnified matter, then upon receipt of indemnification, the Indemnitee shall fully assign to the Indemnitor the entire claim or claims to the extent of the indemnification actually paid by the Indemnitor and the Indemnitor shall thereupon be subrogated with respect to such claim or claims of the Indemnitee. 9. MISCELLANEOUS. 9.1 Powers and Rights Not Waived; Remedies Cumulative. No delay or failure on the part of Abbott in the exercise of any power or right shall operate as a waiver thereof; nor shall any single or partial exercise of the same preclude any other or further exercise thereof, or the exercise of any other power or right, and the rights and remedies of Abbott are cumulative to, and are not exclusive of, any rights or remedies Abbott would otherwise have. 9.2 NOTICE.

ABBOTT LABORATORIES By: ------------------------------------ Name: ---------------------------------- Title: --------------------------------- ARONEX PHARMACEUTICALS, INC. By: ------------------------------------ Name: ---------------------------------- Title: --------------------------------- EXHIBIT A EXHIBIT A TO THE STOCK PURCHASE AGREEMENT IS SUBMITTED AS THE ATTACHED EXHIBIT 3 TO THE SCHEDULE 13D. EXHIBIT B FORM OF OPINION OF COUNSEL 1. The Company (a) is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, (b) has all requisite power and authority to own and operate its properties and to carry on its business as now conducted, and (c) is duly licensed or qualified and is in good standing as a foreign corporation in each jurisdiction wherein the nature of the business transacted by it or the nature of the property owned or leased by it makes such licensing or qualification necessary. 2. The Company has all requisite corporate power and authority to enter into the Agreement and the License Agreement and to execute, issue, sell and deliver the Shares and, subject to satisfaction of the conditions set forth therein, to consummate the transactions contemplated thereby. The execution and delivery of the Agreement, the License Agreement and the certificates representing the Shares and the consummation of the transactions contemplated thereby have been duly authorized by all necessary corporate action on the part of the Company. The Agreement and the License Agreement have been duly executed and delivered by the Company and constitute the valid and binding obligation of the Company, enforceable in accordance with their terms, subject to (a) the effect of applicable bankruptcy, insolvency, reorganization or other similar laws affecting the rights of creditors, (b) the effect or availability of rules of law governing specific performance, injunctive relief or other equitable remedies, and (c) considerations of public policy, including, without limitation, public policy that may limit rights to indemnity or contribution for liabilities arising under federal and state securities laws and regulations thereunder. 3. To our knowledge, no consent, approval, order or authorization of, or registration, declaration or filing with, any Governmental Entity or other Person is required by, or with respect to, the Company in connection with the execution and delivery of the Agreement, the License Agreement or the certificates representing the Shares or the consummation by the Company of the transactions contemplated thereby, except for such consents, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable federal and state securities laws and the laws of any foreign country. 4. The execution and delivery of the Agreement, the License Agreement and the certificates representing the Shares does not or will not, and the consummation of the transactions contemplated thereby will not, conflict with, or result in any violation of or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation under (a) any provision of the Certificate of Incorporation or Bylaws of the Company, or (b) any material agreement or instrument, permit, franchise, license, judgment or order applicable to the Company or its properties or assets that is listed as an exhibit to the Company SEC Documents. 5. The total number of shares of capital stock the Company is authorized to issue is 35,000,000 shares, consisting of 30,000,000 shares of Common Stock and 5,000,000 shares of Preferred Stock. 6. Except as described in the Company SEC Documents, to our knowledge there are no outstanding options, warrants, rights or other securities convertible into or exchangeable for shares of capital stock of the Company or any Subsidiary, other than options to purchase shares of Common Stock reserved for issuance under the Company's stock option plans described in the Company SEC Documents. 7. The Shares have been duly authorized and, when issued in accordance with the Agreement, will be validly issued, fully paid and non-assessable, and the issuance of the Shares is not subject to any preemptive or similar rights created by statute, the Company's Certificate of Incorporation or Bylaws or, to our knowledge, any agreement to which the Company is a party or by which it is bound. 8. The offering and sale of the Shares in accordance with the terms of the Agreement is exempt from the registration requirements of the Securities Act. 9. The Company is not an "investment company" or a person "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended. EXHIBIT C ALTERNATIVE DISPUTE RESOLUTION The parties recognize that a bona fide dispute as to certain matters may arise from time to time during the term of this Agreement which relates to either party's rights and/or obligations. To have such a dispute resolved by this Alternative Dispute Resolution ("ADR") provision, a party first must send written notice of the dispute to the other party for attempted resolution by good faith negotiations between their respective representatives of the affected subsidiaries, divisions, or business units within twenty-eight (28) days after such notice is received (all references to "days" in this ADR provision are to calendar days). If the matter has not been resolved within twenty-eight (28) days of he notice of dispute, or if the parties fail to meet within such twenty-eight (28) days, either party may initiate an ADR proceeding as provided herein. The parties shall have the right to be represented by counsel in such a proceeding. 1. To begin an ADR proceeding, a party shall provide written notice to the other party of the issues to be resolved by ADR. Within fourteen (14) days after its receipt of such notice, the other party may, by written notice to the party initiating the ADR, add additional issues to be resolved within the same ADR. 2. Within twenty-one (21) days following receipt of the original ADR notice, the parties shall select a mutually acceptable neutral to preside in the resolution of any disputes in this ADR proceeding. If the parties are unable to agree on a mutually acceptable neutral within such period, the parties shall request the President of the Center for Public Resources ("CPR"), 366 Madison Avenue, New York, New York 10017 to select a neutral pursuant to the following procedures: (a) The CPR shall submit to the parties a list of not less than five (5) candidates within fourteen (14) days after receipt of the request from the parties, along with a CURRICULUM VITAE for each candidate. No candidate shall be an employee, director, or shareholder of either party or any of their subsidiaries or affiliates. (b) Such list shall include a statement of disclosure by each candidate of any circumstances likely to affect his or her impartiality. (c) Each party shall number the candidates in order of preference (with the number one (1) signifying the greatest preference) and shall deliver the list to the CPR within seven (7) days following receipt of the list of candidates. If a party believes a conflict of interest exists regarding any of the candidates that party shall provide a written explanation of the conflict to the CPR along with its list showing its order of preference for the candidates. Any party failing to return a list of preferences on time shall be deemed to have no order of preference. (d) If the parties collectively have identified fewer than three (3) candidates deemed to have conflicts, the CPR immediately shall designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference. If a tie should result between two candidates, the CPR may designate either candidate. If the parties collectively have identified three (3) or more candidates deemed to have conflicts, the CPR shall review the explanations regarding conflicts and, in its sole discretion, may either (i) immediately designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference, or (ii) issue a new list of not less than five (5) candidates, in which case the procedures set for in subparagraphs 2(a) - 2(d) above shall be repeated. 3. No earlier than twenty-eight (28) days or later than fifty-six (56) days after selection, the neutral shall hold a hearing to resolve each of the issues identified by the parties. The ADR proceeding shall take place at a location agreed upon by the parties. If the parties cannot agree, the neutral shall designate a location other than the principal place of business of either party or any of their subsidiaries or affiliates. 4. At least seven (7) days prior to the hearing, each party shall submit the following to the other party and the neutral: (a) a copy of all exhibits on which such party intends to rely in any oral or written presentation to the neutral; (b) a list of any witnesses such party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; (c) a proposed ruling on each issue to be resolved, together with a request for a specific damage award or other remedy for each issue. The proposed rulings and remedies shall not contain any recitation of the facts or any legal arguments and shall not exceed one (1) page per issue. (d) a brief in support of such party's proposed rulings and remedies, provided that the brief shall not exceed twenty (20) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. Except as expressly set forth in subparagraphs 4(a) - 4(d) above, no discovery shall be required or permitted by any means, including depositions, interrogatories, requests for admissions, or production of documents. 5. The hearing shall be conducted on two (2) consecutive days and shall be governed by the following rules: (a) Each party shall be entitled to five (5) hours of hearing time to present its case. The neutral shall determine whether each party has had the five (5) hours to which it is entitled. (b) Each party shall be entitled, but not required, to make an opening statement, to present regular and rebuttal testimony, documents or other evidence, to cross-examine witnesses, and to make a closing argument. Cross-examination of witnesses shall occur immediately after their direct testimony, and cross-examination time shall be charged against the party conducting the cross-examination. (c) The party initiating the ADR shall begin the hearing and, if it chooses to make an opening statement, shall address not only issues it has raised but also any issues raised by the responding party. The responding party, if it chooses to make an opening statement, also shall address all issues raised in the ADR. Thereafter, the presentation of regular and rebuttal testimony and documents, other evidence, and closing arguments shall proceed in the same sequence. (d) Witnesses shall be excluded from the hearing until closing arguments. (e) Neither affidavits nor settlement negotiations shall be admissible under any circumstances. As to all other matters, the neutral shall have sole discretion regarding the admissibility of any evidence. 6. Within seven (7) days following completion of the hearing, each party may submit to the other party and the neutral a post-hearing brief in support of its proposed rulings and remedies, provided that such brief shall not contain or discuss any new evidence and shall not exceed ten (10) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 7. The neutral shall rule on each disputed issue within fourteen (14) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the parties on each disputed issue but may adopt one party's proposed rulings and remedies on some issues and the other party's proposed rulings and remedies on other issues. The neutral shall not issue any written opinion or otherwise explain the basis of the ruling. 8. The neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with the reasonable legal fees and expenses of the prevailing party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: (a) If the neutral rules in favor of one party on all disputed issues in the ADR, the losing party shall pay 100% of such fees and expenses. (b) If the neutral rules in favor of one party on some issues and the other party on other issues, the neutral shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the parties. The neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 9. The rulings of the neutral and the allocation of fees and expenses shall be binding, non-reviewable, and non-appealable, and may be entered as a final judgment in any court having jurisdiction. 10. Except as provided in paragraph 9 of this Exhibit D or as required by law, the existence of the dispute, any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings, and briefs), and the rulings shall be deemed Confidential Information. The neutral shall have the authority to impose sanctions for unauthorized disclosure of Confidential Information.

If Generic Competition exists in any country of the Territory in which no Valid Claim exists, royalties payable by Abbott for Net Sales in such country shall be reduced by * (*) during the period in which Generic Competition exists. The aggregate total royalty payable to API shall be determined by total Annual Net Sales during each applicable Calendar Year. On or before December 1 of each Calendar Year during the Term, the Parties shall mutually agree on an Annual Net Sales forecast ("Net Sales Forecast") for the following Calendar Year and Abbott shall pay estimated royalties based on the Net Sales Forecasts. If the Factory Cost for a Calendar Year exceeds * (*) of the Net Average Selling Price (as defined below) of the Product for such Calendar Year, the portion of the Factory Cost above * (*) shall be prorated to the Parties in an amount equal to the proration of royalty payments to Net Sales. On or before December 1 of each Calendar Year during the Term, the Parties shall mutually agree on a Net Average Selling Price forecast ("ASP Forecast") and Factory Cost estimate ("Factory Cost Estimate") for the following Calendar Year and, if applicable, adjust royalties based on the ASP Forecast and Factory Cost Estimate. The Parties shall reconcile actual royalties payable for each Calendar Year on or before April 1 of the following Calendar Year. As used in this Section, "Net Average Selling Price" shall mean Net Sales divided by Net Units and "Net Units" shall mean units of the Product actually sold, less returns in accordance with Section 1.17. The Annual Net Sales thresholds set forth in subsections (a) through (e) of this Section 4.1 shall be proportionately reduced: (i) in the Calendar Year in which the First Commercial Sale occurs, by multiplying such Annual Net Sales thresholds by a fraction, (A) the numerator of which shall be the number of days remaining in such Calendar Year as of the First Commercial Sale and (B) the denominator of which shall be 365; and (ii) in the Calendar Year in which the Term expires, by multiplying such Annual Net Sales thresholds by a fraction, (X) the numerator of which shall be the number of days in such Calendar Year prior to the expiration of the Term and (Y) the denominator of which shall be 365. 4.2 LUMP SUM ROYALTY PAYMENTS. In addition to the royalty payments pursuant to Section 4.1 and research and development funding payments pursuant to Sections 3.1 and 3.2, Abbott shall make lump sum royalty payments to API if any or all of the following Net Sales thresholds are attained during the time periods referenced below:
Net Sales Applicable Time Period Payment Amount Level ---------------------- -------------- ----- (a) * * * (b) * * * (c) * * * (d) * * *
Each lump sum royalty payment referenced above shall be payable only once during the Term within ten (10) business days after the end of the applicable time period and shall be payable only if the applicable Net Sales level is attained during the applicable time period. 4.3 ROYALTY REPORTS AND PAYMENTS. Commencing with the first Calendar Quarter in which Abbott, its Affiliates or Unaffiliated Sublicensees make the First Commercial Sale of the Product in the Territory, Abbott shall provide API with a written report of Net Sales on a country-by-country basis within forty-five (45) days after the last day of March, June, September and December for royalties accruing on Net Sales in the United States during the three (3) preceding calendar months and within seventy-five (75) days after the last day of February, May, August and November for royalties accruing on Net Sales in the Territory outside of the United States during the three (3) preceding calendar months. Concurrently with the submission of each such written report, Abbott shall pay or cause to be paid to API the total amount of royalties shown to be due thereon. 4.4 CURRENCY. Abbott shall make all royalty payments to API pursuant to Section 4.2 in U.S. Dollars. Royalty payments earned shall be first determined by Abbott in the currency of the country where the Net Sales were made and then converted by Abbott directly to its equivalent in U.S. Dollars. The rates of exchange for converting the currencies involved to U.S. Dollars as quoted by the WALL STREET JOURNAL, Midwest Edition, as Foreign Exchange Rates quoted in New York as market rate (bid) on the last business day of the quarterly period in which the royalty payments were earned shall be used by Abbott to determine such conversion rates. 4.5 NO ROYALTIES PAYABLE BETWEEN AFFILIATES. No royalties shall be payable to API on sales between Abbott, its Affiliates or Unaffiliated Sublicensees, or between Abbott Affiliates and Unaffiliated Sublicensees. 4.6 NO MULTIPLE ROYALTIES. No multiple royalties shall be payable because the Product, its manufacture, use or sale is or shall be covered by multiple API Patents. 5. PAYMENT, RECORD KEEPING AND AUDIT RIGHTS 5.1 METHOD OF PAYMENT. All payments by either Party to the other Party hereunder (including, but not limited to, Abbott's milestone and research and development payments under Sections 3.1 and 3.2 and royalty payments under Sections 4.1 and 4.2) shall be made without deduction of any withholdings for any purposes other than taxes, if applicable, to the extent required by law. In the event of any tax withholding, the paying Party will provide the receiving Party with the best available evidence of the taxes withheld as well as any relevant certificates or documents required for national, state or local tax credit and reporting purposes. Payments hereunder shall not be creditable against any other amounts payable by the other Party under this Agreement, except as otherwise expressly stated herein. Payments may be made by check or wire transfer to an account designated by the receiving Party. 5.2 RECORD KEEPING AND AUDIT RIGHTS. Each Party shall keep or cause to be kept accurate records relating to Net Sales, royalties, and any other costs and expenses subject to payment or reimbursement by either Party to the other Party in sufficient detail to enable the amounts payable hereunder to be determined. Upon the written request of either Party (but not more frequently than once in any calendar year), the requesting Party may retain an independent certified public accountant, subject to approval by the other Party (which approval shall not be unreasonably withheld), to review such records to verify the accuracy of the payments made or payable hereunder. Such accountant shall be required to execute a confidentiality agreement in a form reasonably acceptable to the audited Party and shall report to the auditing Party only the amount of any underpayment or overcharge. Within ten (10) business days after completion of such review, the Parties shall reconcile any underpayment or overcharge. The auditing Party shall pay the cost of any review of records conducted at its request under this Section. However, if the review establishes underpayment or overcharge by the audited Party of over five percent (5%) during the period of the review, the audited Party shall promptly reimburse the auditing Party for the fees and expenses of the accountant. Such audit rights may be exercised by the Parties only with respect to records for the current calendar year and the preceding two (2) calendar years. 6.

Direct material is identified by specific lot numbers. Items normally included are; Raw drug. Diluting material such as the alcohol. Vial. Vial stopper. Vial seal Inline solution filters and compounding filters. Vial label Single unit carton. Shipper Any other specialized packaging material. DIRECT LABOR COST. Includes the cost of employees directly involved in the manufacture of the Product. Our direct labor employees are classified as Assistants, Operators, Attendants, Technicians, Senior Production Operators, Productions Equipment Specialists, and Group Leaders. The rate per hour includes the average base rate for all direct employees plus a fringe rate that includes vacations, holidays, insurance costs, pension, 401K, bonuses and legally mandated employer taxes. Standard product cost uses an Industrial Engineering estimate of the hours to perform each step of the production process. Additional procedures or employees required to handle explosive material would be added as a direct labor operation. Direct labor operations are normally considered to be: Drug dispensing. Drug mixing. Preparation of the filling equipment. Preparation of components such as washing vial stoppers. Preparation of printed materials, primarily labels. Filling of the vial. Post filling light inspection. Lyophilization Labeling. Packing. VARIABLE OVERHEAD COST. Includes the costs of operating the plant which change as the volume of production in the plant changes. The major components of variable overhead are related to the production operator and include their overtime, time spent for training and plant meetings, and their uniforms and gowns. Any specialized employee safety equipment such as used in an explosion proof environment would be included in this category. Cost included in this category are assigned to standard product cost as a rate per hour applied to direct labor hours identified above. FIXED OVERHEAD COSTS. Includes the other costs associated with operating a manufacturing plant. The key components are the cost of the quality assurance organization, material planning, purchasing, receiving, and warehousing, plant maintenance, utilities and engineering, the health and safety group, production supervision, and fixed costs such as depreciation taxes, and insurance. Investment in explosive proof equipment and changes to the facility required to handle explosive material would be included in this category. These costs are assigned to standard product cost based on fully utilized plant capacity. The standard product cost development process occurs once per year in the mid-summer time period. At that time, assumptions are made regarding inflation rates for raw material and wages, productivity improvements, and plant utilization levels.

EXHIBIT D ALTERNATIVE DISPUTE RESOLUTION The parties recognize that a bona fide dispute as to certain matters may arise from time to time during the term of this Agreement which relates to either party's rights and/or obligations. To have such a dispute resolved by this Alternative Dispute Resolution ("ADR") provision, a party first must send written notice of the dispute to the other party for attempted resolution by good faith negotiations between their respective representatives of the affected subsidiaries, divisions, or business units within twenty-eight (28) days after such notice is received (all references to "days" in this ADR provision are to calendar days). If the matter has not been resolved within twenty-eight (28) days of he notice of dispute, or if the parties fail to meet within such twenty-eight (28) days, either party may initiate an ADR proceeding as provided herein. The parties shall have the right to be represented by counsel in such a proceeding. 1. To begin an ADR proceeding, a party shall provide written notice to the other party of the issues to be resolved by ADR. Within fourteen (14) days after its receipt of such notice, the other party may, by written notice to the party initiating the ADR, add additional issues to be resolved within the same ADR. 2. Within twenty-one (21) days following receipt of the original ADR notice, the parties shall select a mutually acceptable neutral to preside in the resolution of any disputes in this ADR proceeding. If the parties are unable to agree on a mutually acceptable neutral within such period, the parties shall request the President of the Center for Public Resources ("CPR"), 366 Madison Avenue, New York, New York 10017 to select a neutral pursuant to the following procedures: (a) The CPR shall submit to the parties a list of not less than five (5) candidates within fourteen (14) days after receipt of the request from the parties, along with a CURRICULUM VITAE for each candidate. No candidate shall be an employee, director, or shareholder of either party or any of their subsidiaries or affiliates. (b) Such list shall include a statement of disclosure by each candidate of any circumstances likely to affect his or her impartiality. (c) Each party shall number the candidates in order of preference (with the number one (1) signifying the greatest preference) and shall deliver the list to the CPR within seven (7) days following receipt of the list of candidates. If a party believes a conflict of interest exists regarding any of the candidates that party shall provide a written explanation of the conflict to the CPR along with its list showing its order of preference for the candidates. Any party failing to return a list of preferences on time shall be deemed to have no order of preference. (d) If the parties collectively have identified fewer than three (3) candidates deemed to have conflicts, the CPR immediately shall designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference. If a tie should result between two candidates, the CPR may designate either candidate. If the parties collectively have identified three (3) or more candidates deemed to have conflicts, the CPR shall review the explanations regarding conflicts and, in its sole discretion, may either (i) immediately designate as the neutral the candidate for whom the parties collectively have indicated the greatest preference, or (ii) issue a new list of not less than five (5) candidates, in which case the procedures set for in subparagraphs 2(a) - 2(d) above shall be repeated. 3. No earlier than twenty-eight (28) days or later than fifty-six (56) days after selection, the neutral shall hold a hearing to resolve each of the issues identified by the parties. The ADR proceeding shall take place at a location agreed upon by the parties. If the parties cannot agree, the neutral shall designate a location other than the principal place of business of either party or any of their subsidiaries or affiliates. 4. At least seven (7) days prior to the hearing, each party shall submit the following to the other party and the neutral: (a) a copy of all exhibits on which such party intends to rely in any oral or written presentation to the neutral; (b) a list of any witnesses such party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; (c) a proposed ruling on each issue to be resolved, together with a request for a specific damage award or other remedy for each issue. The proposed rulings and remedies shall not contain any recitation of the facts or any legal arguments and shall not exceed one (1) page per issue. (d) a brief in support of such party's proposed rulings and remedies, provided that the brief shall not exceed twenty (20) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. Except as expressly set forth in subparagraphs 4(a) - 4(d) above, no discovery shall be required or permitted by any means, including depositions, interrogatories, requests for admissions, or production of documents. 5. The hearing shall be conducted on two (2) consecutive days and shall be governed by the following rules: (a) Each party shall be entitled to five (5) hours of hearing time to present its case. The neutral shall determine whether each party has had the five (5) hours to which it is entitled. (b) Each party shall be entitled, but not required, to make an opening statement, to present regular and rebuttal testimony, documents or other evidence, to cross-examine witnesses, and to make a closing argument. Cross-examination of witnesses shall occur immediately after their direct testimony, and cross-examination time shall be charged against the party conducting the cross-examination. (c) The party initiating the ADR shall begin the hearing and, if it chooses to make an opening statement, shall address not only issues it has raised but also any issues raised by the responding party. The responding party, if it chooses to make an opening statement, also shall address all issues raised in the ADR. Thereafter, the presentation of regular and rebuttal testimony and documents, other evidence, and closing arguments shall proceed in the same sequence. (d) Witnesses shall be excluded from the hearing until closing arguments. (e) Neither affidavits nor settlement negotiations shall be admissible under any circumstances. As to all other matters, the neutral shall have sole discretion regarding the admissibility of any evidence. 6. Within seven (7) days following completion of the hearing, each party may submit to the other party and the neutral a post-hearing brief in support of its proposed rulings and remedies, provided that such brief shall not contain or discuss any new evidence and shall not exceed ten (10) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 7. The neutral shall rule on each disputed issue within fourteen (14) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the parties on each disputed issue but may adopt one party's proposed rulings and remedies on some issues and the other party's proposed rulings and remedies on other issues. The neutral shall not issue any written opinion or otherwise explain the basis of the ruling. 8. The neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with the reasonable legal fees and expenses of the prevailing party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: (a) If the neutral rules in favor of one party on all disputed issues in the ADR, the losing party shall pay 100% of such fees and expenses. (b) If the neutral rules in favor of one party on some issues and the other party on other issues, the neutral shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the parties. The neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 9. The rulings of the neutral and the allocation of fees and expenses shall be binding, non-reviewable, and non-appealable, and may be entered as a final judgment in any court having jurisdiction. 10. Except as provided in paragraph 9 of this Exhibit D or as required by law, the existence of the dispute, any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings, and briefs), and the rulings shall be deemed Confidential Information. The neutral shall have the authority to impose sanctions for unauthorized disclosure of Confidential Information. EXHIBIT E API TRADEMARK APPLICATIONS AND REGISTRATIONS API TRADEMARKS REGISTERED
