ARTICLE 4 - ROYALTY PAYMENTS, REPORTS AND RECORDS

4.1   Sepracor shall deliver to RPR within [**] days following the end of each
      Payment Period, beginning with the first Payment Period, a written report

            Products; and

      (b)   the total Royalties due for the Payment Period.

4.2   Each Royalty Statement for a Payment Period required by Section 4.1 above
      shall be accompanied by full payment to RPR of the payments due to RPR
      under Articles 3 and 4.

4.3   With regard to any payments due to RPR, the following shall apply:

       (a)  All payments to RPR pursuant to this Agreement shall be made by wire
            transfer and in accordance with written instructions to be provided
            by RPR in accordance with Article 15. All such payments shall be
            made in United States Dollars ("Dollars").

       (b)  Whenever any payment hereunder shall be stated to be due on a day
            which is not a Business Day, such payment shall be made on the
            immediately succeeding Business Day.

       (c)  Payments hereunder shall be considered to be made as of the day on
            which they are received in RPR's designated bank account.

       (d)  All payments due to RPR hereunder but not paid by Sepracor on the
            due date thereof shall bear interest at the rate which is the lesser
            of: (i) LIBOR plus two percent (2%) per annum; and (ii) the maximum
            lawful interest rate permitted under applicable law. Such interest
            shall accrue on the balance of unpaid amounts from time to time
            outstanding from the date on which portions of such amounts become
            due and owing until payment thereof in full.

4.4   Any income or other taxes which Sepracor is required by law to pay or
      withhold on behalf of RPR with respect to Royalties, and any interest
      thereon, payable to RPR under this Agreement shall be deducted from the
      amount of such Royalties and interest due, and paid or withheld, as
      appropriate, by Sepracor on behalf of RPR. In such event, Sepracor shall
      timely pay or remit all amounts so withheld to the appropriate taxing
      authorities on RPR's behalf and promptly provide RPR with a written tax
      receipt for such amount issued by such taxing authority. Sepracor shall
      obtain for RPR, at its request, any other documentation, receipt or
      certificate necessary or desirable for RPR to apply for and/or


                                       7


      receive any corresponding tax refund or credit under any applicable tax
      law or treaty. Any such tax required to be paid or withheld shall be an
      expense of and borne solely by RPR. The foregoing sentences
      notwithstanding, the parties hereto will reasonably cooperate in
      completing and filing documents required under the provisions of any
      applicable tax laws or under any other applicable law, in order to enable
      Sepracor to make such payments to RPR without any deduction or
      withholding.

4.5   Sepracor shall keep and maintain, and shall cause its Affiliates to keep
      and maintain, complete and accurate records and books of account in
      accordance with Generally Accepted Accounting Principles in sufficient
      detail and form so as to enable amounts payable under Articles 3 and 4 to
      be determined, including but not limited to, true and accurate records of
      sales of Products and calculations of Net Sales and Royalties. RPR shall
      have the right, at its own cost and expense, to audit the records of
      Sepracor and its Affiliates using a nationally recognized firm of
      independent certified accountants reasonably acceptable to Sepracor. Such
      accountants will have access on reasonable notice to Sepracor and its
      Affiliates' records during reasonable business hours for the sole purpose
      of verifying the Royalties payable as provided in this Agreement for the
      three preceding years provided, however, that if there is a good faith
      dispute between the parties continuing at the end of any such three (3)
      year period with respect to such books or records, then the time period
      hereunder to maintain such books and records under dispute and for any
      subsequent period shall be extended until such time as the dispute is
      finally resolved. This right may not be exercised more than once in any
      calendar year, and once a calendar year is audited it may not be
      reaudited, provided that if there is a dispute as to any audited year,
      such year and any subsequent year may be reaudited until such time as the
      dispute is resolved. Said accountant shall disclose to RPR only
      information relating solely to the accuracy of the Royalty Statements
      provided to RPR and the payments made to RPR under this Agreement. The
      provisions of this Section 4.5 shall survive the expiration or sooner
      termination of this Agreement.

4.6   Any underpayment determined as a result of an audit conducted under this
      Article shall be paid to RPR within twenty-five (25) days after the date
      on which the accountant conducting the audit issues a written report to
      RPR and Sepracor containing the results of the audit. If any underpayment
      by Sepracor is greater than ten percent (10%) of the amount previously
      paid to RPR for the relevant Payment Period, the costs and expenses of the
      audit shall be paid for by Sepracor. Any overpayment shall be credited to
      the next payment to RPR due hereunder.

ARTICLE 5 - COOPERATION, TECHNOLOGY TRANSFER, AND INVENTIONS

5.1   RPR shall use good faith reasonable efforts to consult and cooperate with
      Sepracor with respect to the filing of any patent applications for
      Improvements and the maintenance of patents issued thereon including,
      without limitation, by executing and obtaining from employees assignments
      and other documents reasonably required in connection therewith,


                                       8


      provided, however, that RPR may refuse to execute such documents if RPR
      makes a good faith reasonable determination that any such document is
      factually or legally incorrect.

      order to avoid loss of any rights which may otherwise be available to the
      parties under the U.S. Drug Price Competition and Patent Term Restoration
      Act of 1984 and other similar measures. Without limiting the foregoing,
      each of Sepracor and RPR agrees to provide the other with reasonable
      information and assistance in order to permit the timely filing of an
      application for patent term extension within the sixty (60) day period
      following NDA approval to market Product in the United States.

5.3   After the Effective Date, RPR shall provide Sepracor full access to the
      information referenced in Section 2.3 hereof and shall use good faith
      reasonable efforts in fully cooperating with Sepracor in order to enable
      Sepracor to obtain Regulatory Approval of Products. At Sepracor's request,
      RPR shall disclose to Sepracor in writing, or via mutually acceptable
      electronic media, copies or reproductions of all written RPR Know-How
      reasonably available to RPR or its Affiliates in order to enable Sepracor
      to obtain Regulatory Approval of Products. . In addition, during the term
      of this Agreement, RPR shall promptly disclose to Sepracor in writing, or
      via mutually acceptable electronic media, on an ongoing basis copies or
      reproductions of all Improvements that are reasonably necessary to
      research, develop, register, manufacture, market, use or sell Product.
      Such Improvements shall be automatically deemed to be within the scope of
      the licenses granted herein without payment of any additional
      compensation. Sepracor shall have the right to use for all purposes in
      connection with Regulatory Approval or any regulatory application for
      Product in the Territory all RPR Know-How and other information disclosed
      pursuant to this Section and under this Agreement. Upon Sepracor's
      request, RPR shall provide reasonable technical assistance to enable
      Sepracor to utilize RPR Know-How to obtain Regulatory Approval of
      Products, and from time to time at Sepracor's reasonable request, RPR
      shall use good faith reasonable efforts to assist Sepracor in providing
      responses to questions that may be raised by regulatory authorities in
      connection with Sepracor's applications for Regulatory Approval of
      Products. Sepracor shall be solely responsible for obtaining all
      Regulatory Approvals related to the Product.

5.4   RPR shall use good faith reasonable efforts to cooperate with Sepracor or
      its counsel in connection with prosecution of RPR Applications. The
      parties acknowledge that assignment of the RPR Application to Sepracor
      leaves Sepracor as the only real party in interest in the Interference.
      Sepracor shall notify the PTO Administrative Patent Judge assigned to the
      Interference of the assignment no later than ten (10) days after the
      Effective Date of this Agreement, and shall copy RPR interference counsel
      at Finnegan, Henderson, Farabow, Garrett & Dunner on this notification.
      Sepracor shall make a good faith determination of priority of invention
      and of any other issues that need to be determined relating to the RPR
      Application and Sepracor Patent involved in the Interference.

         Securities and Exchange Commission. Asterisks denote omissions.

      RPR shall use good faith reasonable efforts to cooperate with Sepracor in
      connection with Sepracor's determination(s), including providing
      information, documents, or other materials RPR or its Affiliates or
      counsel have in its possession that is requested by Sepracor and agreed in
      good faith by RPR and Sepracor or its counselto be reasonably necessary to
      Sepracor's good faith determination(s). In addition, at Sepracor's or its
      counsel's request, RPR shall execute documents reasonably necessary to
      Sepracor's good faith determination(s) or prosecution of RPR Applications,
      provided, however, that RPR may refuse to execute such documents if RPR
      makes a good faith reasonable determination that any such document is
      factually or legally incorrect.

      under Articles 5 and 6, the following shall apply: (1) RPR shall provide a
      cumulative total of eighty (80) hours of such cooperation or assistance
      free of charge, and (2) thereafter, Sepracor shall reimburse RPR for
      reasonable fully allocated costs and expenses incurred by RPR in providing
      such cooperation or assistance after receipt of a detailed written invoice
      from RPR for such costs and expenses.

ARTICLE 6 - INFRINGEMENT

      Sepracor shall have the sole right but not the obligation to enforce at
      its expense the RPR Applications. In any suit or dispute involving
      infringement of the RPR Applications, or any litigation necessary to
      enforce or defend the RPR Applications, the parties shall use good faith
      reasonable efforts to cooperate, and upon the request and at the expense
      of Sepracor, RPR shall make available to Sepracor at reasonable times and
      under appropriate conditions company files that pertain to the RPR
      Application or the invention it claims, excluding any materials that are
      privileged under the attorney-client privilege or the work-product
      doctrine, and RPR employees having personal knowledge concerning the RPR
      Application or the invention it claims, and information concerning the
      last known address of former RPR employees having personal knowledge
      concerning the RPR Application or the invention it claims. Any recovery or
      damages derived from enforcement of any RPR Application shall be used to
      first reimburse Sepracor for its documented expenses and costs relating to
      such enforcement. Thereafter, RPR shall receive the lesser of (a) an
      amount equal to [**] of the net sales of Product by the infringing party,
      or (b) [**] of the compensatory damages. Any punitive damages, exemplary
      damages, or other enhanced damages shall be retained solely by Sepracor.

      employees, agents, consultants, Affiliates, Licensees or clinical
      investigators to whom disclosure is to be made to hold in confidence and

      permitted by this Agreement. Each party shall use at least the same
      standard of care as it uses to protect its own Confidential Information to
      ensure that such employees, agents, consultants and clinical investigators
      do not disclose or make any unauthorized use of such Confidential
      Information. Each party shall promptly notify the other upon discovery of
      any unauthorized use or disclosure of the Confidential Information. The
      obligations of confidentiality set forth in this Section 7.1 shall not
      apply when and to the extent that Confidential Information:

      7.1.1  was already known to the receiving party, other than under an
             obligation of confidentiality, at the time of disclosure by the
             other party as demonstrated by written documents;

      7.1.2  was generally available to the public or otherwise part of the
             public domain at the time of its disclosure to the other party;

      7.1.3  becomes generally available to the public or otherwise part of the
             public domain after its disclosure and other than through any act
             or omission of the receiving party in breach of this Agreement;

      7.1.4  was disclosed to the receiving party, other than under an
             obligation of confidentiality, by a Third Party who had no
             obligation to the other party not to disclose such information;

      7.1.5  can be demonstrated to have been independently developed by the
             receiving party without reference to the disclosure by the other
             party; or

      7.1.6  is required to be disclosed by the receiving party to regulatory
             authorities in connection with registration, marketing,
             distribution, use, or sale of Product.

7.2   The material financial terms of the Agreement shall be considered the
      Confidential Information of both parties.

7.3   Any other provision of this Agreement notwithstanding, each party may
      disclose the Confidential Information to the extent such disclosure is
      reasonably necessary in filing or prosecuting patent applications,
      prosecuting or defending litigation or complying with


                                       11


      applicable governmental regulations. In addition, either party may
      disclose such Confidential Information to its Affiliates, and Sepracor may
      disclose such Confidential Information to Licensees; provided, however, in
      connection with any such disclosure the disclosing party shall use
      diligent efforts to secure confidential treatment of such information.

7.4   The parties shall undertake to ensure that all their employees who have
      access to Confidential Information of the other party are under
      obligations of confidentiality consistent with those provided in Section
      7.1.

7.5   To the extent legally required, the parties agree to comply with the
      requirements of 35 U.S.C.ss.135(c) relating to submission of agreements
      between the parties to the U.S. Patent and Trademark Office.

ARTICLE 8 - TERM

      This Agreement will commence as of the Effective Date and, unless sooner
      terminated as provided hereunder, shall terminate on the expiration of the
      royalty obligations of Article 3, after which time Sepracor will have a

      the Effective Date, or if Sepracor breaches its obligations under Section
      2.4, then this Agreement shall terminate ten (10) years from the Effective
      Date, or thirty (30) days after RPR gives notice to Sepracor of such
      breach, as applicable. Upon any such early termination of this Agreement,
      all rights to RPR Know-How and Improvements licensed hereunder to Sepracor
      shall revert to RPR, and Sepracor and its Affiliates and Licensees shall
      make no further use of the same.

ARTICLE 9 - BREACH AND TERMINATION

      In the event Sepracor or RPR are in material breach of any of the
      respective obligations and conditions contained in this Agreement, the
      other party shall be entitled to give the party in breach notice requiring
      it to cure such material breach. If such material breach is not cured
      within ninety (90) days after receipt of such notice, the notifying party
      may seek a determination of damages for the breach from the breaching
      party. Nothing herein shall prevent either party hereto from exercising
      such party's right to obtain specific performance or temporary or
      permanent injunctive relief or other equitable relief.

      this Agreement.

ARTICLE 12 - INDEMNIFICATION

12.1   Except as otherwise provided to the contrary in this Agreement, Sepracor
       agrees to defend, indemnify, and hold harmless RPR, its successors and
       assigns, and its officers, directors, employees, stockholders, agents,
       Affiliates and any person who controls any of such persons (an
       "Indemnified RPR Party") at Sepracor's cost and expense (including
       reasonable attorneys' fees) from and against any and all liabilities,
       claims, demands, judgments, losses, costs, damages, fees or expenses
       whatsoever (collectively, "Liability") that such Indemnified RPR Party
       may sustain, suffer or incur arising out of or in connection with the
       manufacture, commercialization, marketing, sale or use of any Product in
       the Territory, including, but not limited to, any actual or alleged
       injury, damage, death or other consequence occurring to any person as a
       result, directly or indirectly, of the possession, use or consumption of
       any Product, whether claimed by reason of breach of warranty, negligence,
       product defect or otherwise, and regardless of the form in which any such
       claim is made. Notwithstanding the foregoing, Sepracor shall have no
       obligation under this Agreement to indemnify, defend or hold harmless any
       Indemnified RPR Party with respect to any Liability which result from
       willful misconduct or negligent acts or omissions of RPR, its Affiliates,
       or any of their respective employees, officers, directors or agents.


                                       15


12.2  Except as otherwise provided to the contrary in this Agreement, RPR shall
      defend, indemnify and hold harmless Sepracor, its successors and assigns,
      and its officers, directors, employees, stockholders, agents, Affiliates
      and any person who controls any of such persons (an "Indemnified Sepracor
      Party") at RPR's cost and expense (including reasonable attorneys' fees
      incurred by such Indemnified Sepracor Party in connection therewith) from
      and against any and all liabilities, claims, demands, judgments, losses,
      costs, damages, fees, or expenses whatsoever (collectively, "Liability")
      that such Indemnified Sepracor Party may sustain, suffer or incur to the
      extent that such Damages are attributed to any breach of any
      representation, warranty, covenant or agreement of RPR contained in this
      Agreement. Notwithstanding the foregoing, RPR shall have no obligation
      under this Agreement to indemnify, defend or hold harmless any Indemnified
      Sepracor Party with respect to any Liability which results from willful
      misconduct or negligent acts or omissions of Sepracor, its Affiliates, or
      any of their respective employees, officers, directors or agents.

12.3  Each party agrees to promptly give the other party notice of any claim for
      which indemnification might be sought. Failure of an indemnified party to
      provide notice of a claim to the indemnifying party shall affect the
      indemnified party's right to indemnification only to the extent that such
      failure has a material adverse effect on the indemnifying party's ability
      to defend or the nature or the amount of the Liability. The indemnifying
      party shall have the right to assume the defense of any suit or claim
      related to the Liability if it has assumed responsibility for the suit or
      claim in writing; however, if in the reasonable judgment of the
      indemnified party, such suit or claim involves an issue or matter which
      could have a materially adverse effect on the business operations or
      assets of the indemnified party, the indemnified party may waive its
      rights to indemnity under this Agreement and control the defense or
      settlement thereof, but in no event shall any such waiver be construed as
      a waiver of any indemnification rights such party may have at law or in
      equity. If the indemnifying party defends the suit or claim, the
      indemnified party may participate in (but not control) the defense thereof
      at its sole cost and expense.

12.4  Neither party may settle a claim or action related to a Liability without
      the consent of the other party, if such settlement would impose any
      monetary obligation on the other party or require the other party to
      submit to an injunction or otherwise limit the other party's rights under
      this Agreement; provided that such consent shall not unreasonably be
      withheld or delayed.

12.5  With respect to any claim by one party against the other arising out of
      this Agreement, the parties expressly agree that the liability of such
      party to the other party shall be limited under this Agreement or
      otherwise at law or equity to direct damages only and in no event shall a
      party be liable for, punitive, exemplary or consequential damages.

ARTICLE 16 - WAIVER

      Any term or provision of this Agreement may be waived at any time by the
      party entitled to the benefit thereof by a written instrument duly
      executed by such party. The failure of any party at any time or times to
      require performance of any provision hereof shall in no manner affect the
      right of such party at a later time to enforce the same or any other
      provision of this Agreement. No waiver of any condition or of the breach
      of any provision of this Agreement in one or more instances shall operate
      or be construed as a waiver of any other condition or subsequent breach.

ARTICLE 17 - ENTIRE AGREEMENT

      This Agreement constitutes the entire agreement between the parties hereto
      concerning the subject matter hereof and any representation, promise or
      condition in connection therewith, not incorporated herein, shall not be
      binding upon either party. This Agreement, including without limitation
      the Schedules attached hereto, are intended to define the full extent of
      the legally enforceable undertakings of the parties hereto, and no promise
      or representation, written or oral, which is not set forth explicitly
      herein is intended by either party to be legally binding. This Agreement
      may only be modified, amended or supplemented by an instrument in writing
      executed by RPR and Sepracor.

18.1  Except as otherwise provided herein, this Agreement is not assignable
      either in whole or in part without the prior written consent of the other

      any of its Affiliates or to any successor by merger or sale of
      substantially of all of its business unit to which the Agreement relates.

18.2  This Agreement will be binding upon successors and permitted assigns of
      the parties and the name of a party appearing herein will be deemed to
      include the name of such party's successor's and permitted assigns to the
      extent necessary to carry out the intent of this section.

ARTICLE 20 - PUBLICITY

      Except as otherwise specifically provided to the contrary herein, neither
      party will issue any press release, publication, presentation, or any
      other public announcement relating to this Agreement without obtaining the
      other party's prior written approval, which approval will not be
      unreasonably withheld. Sepracor shall be permitted to issue a press
      release concerning this Agreement, which is agreed to by RPR and Sepracor,
      and such agreement shall not be unreasonably withheld or delayed. The
      parties further agree to use reasonable efforts to keep terms of this
      Agreement confidential, including with respect to submissions that
      Sepracor may be required to make to regulatory authorities, to the extent
      that such protection may be available through said regulatory authorities.
      Notwithstanding any of the foregoing, each party may use the substance of
      previously approved public announcements and the substance of other public
      announcements of the other party concerning the subject matter of this
      Agreement without prior notice.

ARTICLE 21 - UNENFORCEABLE PROVISIONS

      The provisions of this Agreement shall be deemed severable and the
      invalidity or unenforceability of any provision shall not affect the
      validity or enforceability of the other provisions hereof. If any
      provision of this Agreement, or the application thereof to any person or
      entity or any circumstance, is invalid or unenforceable, (i) a suitable
      and equitable provision shall be substituted therefore in order to carry
      out, so far as may be valid and enforceable, the intent and purpose of
      such invalid and unenforceable provision and (ii) the remainder of this
      Agreement and the application of such provision to other persons, entities
      or circumstances shall not be affected by such invalidity or
      unenforceability, nor shall such invalidity or unenforceability affect
      such provision, or the application thereof, in any other jurisdiction.

      includes the singular, wherever so required by fact or context.
