      charges paid by DOV to the taxing authorities will be secured by DOV and
      sent to ACY.

6.8   In case of any delay in payment by DOV to ACY not occasioned by force

      DOV undertakes not to make any admission of liability to a claimant or
      plaintiff or his or her legal representative or insurer and not to sign
      any agreement in respect of such proceedings without ACY's previous
      written consent not to be unreasonably withheld.

      When DOV, because of the settlement with ACY's consent of the claimed
      infringement, or a final unappealable or non-appealed judgment of a court
      of competent jurisdiction, isrequired to make payments to one or more
      third parties to obtain a license without which the marketing of the
      Marketed Product could not be made in a given country, DOV may deduct such
      payments from the royalty payments due to ACY hereunder, provided however
      that in no event shall the royalty rate be reduced by more than [***] of
      that which would otherwise be due ACY.

12.2  DOV shall promptly inform ACY of any suspected infringement of any of ACY
      Patents by a third party and provide ACY with any available evidence of
      such suspected infringement.

      ACY shall have the right but not the obligation to institute any claim,
      suit or proceeding against an infringer or a presumed infringer to protect
      and defend ACY Patents. ACY shall control the prosecution of any such suit
      or claim, including without limitation the choice of counsel and shall
      settle or dispose of any such suit or claim. DOV shall provide ACY with
      all reasonable assistance (other than financial) required to institute and
      maintain such proceedings. In the event ACY so elects, ACY shall bear the
      entire costs of such prosecution and shall be entitled to retain after
      deducting the costs and expenses

      borne by ACY in prosecuting the claim of infringement, 90% (ninety
      percent) of the amount of any recovery, court award or settlement.

      DOV shall not institute any negotiations or legal proceedings with respect
      to any such infringement without prior written consent of ACY, but shall
      have the right to institute infringement proceedings against a third party
      in the event that ACY would elect not to do so. In such event, DOV shall
      bear the entire costs and expenses of such proceedings. ACY shall provide
      DOV with all reasonable assistance (other than financial) required to
      institute and maintain such proceedings. In such event, DOV shall be
      entitled to retain 90% ( ninety percent) of the proceeds of any such
      recovery, after first deducting the costs and expenses borne by DOV in
      initiating and maintaining such infringement action.

ARTICLE 13.0 DURATION AND TERMINATION

13.1  This Agreement shall be binding on the parties as of the day of its
      execution but shall have no force or effect until either the parties
      determine that notification under Title II of the Hart-Scott-Rodino
      Antitrust Improvements Act of 1976, 15 U.S.C. 18a, and the regulations
      promulgated thereunder, 16 C.F.R 801.1 et seq., is not required or if the
      parties determine that such notification is required, the waiting period
      shall have expired or been terminated. If a notification filing is
      required, the parties will, at their own expense, prepare and make all
      appropriate filings. The parties shall cooperate in the antitrust
      clearance process and hereby agree to furnish promptly to the FTC and the
      Antitrust Division of the Department of Justice such additional
      information reasonably


                                       17
<Page>

      requested by them in connection with such filings. In the event that the
      waiting period has not expired or been terminated within six (6) months
      after the date of signature of this agreement by both parties, the parties
      shall revert to their status before signing and this agreement shall be of
      no force and effect, except for Articles 7, 10, and 11 which shall survive
      pursuant to their terms. Thereafter, the Agreement shall continue in full
      force and effect in each country of the Territory until the later of
      expiration of the ACY Patents in such country or a period of ten (10)
      years following the launch of each such Product or Marketed Product by DOV
      or its sublicensee(s) in each country of the Territory.

13.2  Upon expiration of this Agreement with respect to each country of the
      Territory, DOV shall be deemed to have a fully-paid, royalty-free license
      with the right to make or have made, use or sell Product and Marketed
      Product as well as to freely utilize all data generated hereunder or
      received from ACY by DOV without DOV's having further obligation to ACY,
      except for maintaining confidentiality as required by Article 7.1 of this
      Agreement.

13.3  DOV shall be free to terminate this entire Agreement and surrender and
      return to ACY all rights acquired by DOV hereunder in its own discretion
      at any time upon 90 days' prior written notice at which time all license
      rights granted hereunder shall come to an end.

13.4  In the event that a party hereto shall be presumed by the other to have
      breached any material condition herein contained, the complaining party
      shall be required to provide a formal written notice of such presumed
      breach, requesting rectification within a sixty-day


                                       18
<Page>

      period from the date of receipt of such notice. The party presumed to be
      in breach of the Agreement shall either submit a commercially reasonable
      plan for rectification within 45 days of receipt of notice (if the breach
      cannot be rectified within the sixty-day period), or take appropriate
      steps to remedy the breach if capable of remedy within such period. If
      within the said sixty-day period neither the aforesaid plan shall have
      been submitted, nor the breach cured, the party alleging breach shall then
      be entitled to terminate this Agreement, thereby surrendering all rights
      granted hereunder, by written notice to the other party, such termination
      having immediate effect.

13.5  This Agreement may be terminated at once by ACY giving notice to DOV if
      DOV is insolvent or has committed an act of bankruptcy or an order is made
      or resolution passed for the winding up of either party.

13.6  In the event this Agreement is terminated prior to its full term pursuant
      to paragraph 13.3 by DOV or pursuant to paragraphs 13.4 or 13.5 by ACY,
      DOV shall within 30 days of such event transfer to ACY all information,
      data and know-how of any kind relating to Product and shall authorize the
      transfer of all governmental approvals for the Product to ACY, in addition
      to DOV's right derived from all License Agreements between DOV and its
      third party partners relative to Product and Marketed Product.

      parties hereto and the successors to substantially the entire business and

17.1  None of the parties shall be responsible for failure or delay in the

ARTICLE 18.0 MISCELLANEOUS

18.1  This Agreement and the Schedules hereto constitute the full understanding
      and entire Agreement between the parties and supersede any and all prior
      oral or written understandings and agreements with respect to the subject
      matter hereof. This Agreement shall not be effective until duly signed by
      officers of both ACY and DOV. No terms, conditions, understandings or
      Agreements purporting to modify, amend or vary this Agreement shall be
      binding unless made in writing and signed by the parties hereto. It is
      mutually agreed that no party has relied upon any representations or
      statements of any third party except as stated herein.

18.2  The invalidity or unenforceability of an Article or any part of an Article
      of this Agreement in any jurisdiction shall not cause the invalidity of
      the whole Agreement as to such jurisdiction, and shall not affect the
      validity or enforceability of such Article or such part of an Article in
      any other jurisdiction. The parties shall replace any Article or part of
      an Article found invalid or unenforceable by alternative provisions which
      shall be as


                                       22
<Page>

      similar as possible in their conditions with regard to their spirit and
      commercial effect. If this Agreement in any jurisdiction is found to be
      invalid or unenforceable, the parties shall replace it by an alternative
      Agreement which shall be as similar as possible in its conditions with
      regard to its spirit and commercial effect.

18.3  The failure of either party on any occasion to require the performance by
      the other of any provision hereof shall in no manner affect the right of
      such party to enforce the same on a subsequent occasion. The waiver by
      either party of any breach of any provision hereof shall at no time be
      construed to be a waiver of any succeeding breach of that or any other
      provision or a waiver of the provision itself.

18.4  This Agreement shall not constitute either party as the joint venturer,
      legal representative or agent of the other party for any purpose
      whatsoever. Neither party shall have any right or authority to assume or
      create any obligation or responsibility for or on behalf of the other
      party or to otherwise bind the other party.

18.5  The parties recognize that this is a master Agreement covering a number of
      countries. If for any country in the Territory it becomes necessary to
      execute a separate instrument for such country in order to satisfy local
      regulatory requirements, the parties agree to execute such further
      instrument, which shall to the extent permitted by the laws of the country
      conform to the terms and conditions of this Agreement.

18.6  This Agreement and the Schedules and Exhibits hereto are originally
      prepared and signed in the English language. If any translation into any
      other language is legally required for purposes of governmental filings,
      the parties shall arrange for such translation, and the costs thereof
      shall be borne by the party legally required to make such filing. In the
      event of any question or dispute as to the meaning or interpretation of
      any term, condition or provision of this Agreement, or any Schedule or
      Exhibit hereto, the English language version shall in all events govern
      for all purposes whatsoever.

18.7  Termination of this Agreement for any reason, or expiration of this
      Agreement, will not affect: (i) obligations, including the payment of any
      Scheduled Payments or royalties which have accrued as of the date of
      termination or expiration, and (ii) rights and obligations which, from the
      context thereof, are intended to survive termination or expiration of this
      Agreement.

18.8  This Agreement is executed simultaneously in counterparts, each of which
      shall be deemed an original, but all of which shall constitute but one and
      the same instrument.
