      necessary to complete a given milestone or the Project as a whole will
      exceed the projected hours by more than 10%, INTELGENX shall notify AZUR
      in writing of same and AZUR shall have a period of ten (10) days to notify
      INTELGENX in writing whether it wishes to proceed or not with the Project
      on the basis of INTELGENX estimated increase of fees, it being
      understood, for greater certainty, that the Project will terminate should
      AZUR reject the increased estimate as specified above.

|           | 5.11                           | Audit. INTELGENX shall have the
      right, at its own expense, for any period during which the Product is sold by AZUR hereunder and for one (1)
      year thereafter, to have an independent public
      accountant, reasonably acceptable to AZUR, audit AZURs financial books and records of account pertaining to Net
      Sales. All such audits shall be conducted not more
      than once per year, during normal business hours, and upon reasonable prior notice. Notwithstanding the
      foregoing, in no event shall INTELGENX have the
      right to audit any period previously audited or to audit any period ending more than two years prior to the date such audit
      is commenced. Any amounts determined pursuant to
      any such audit to have been overpaid or underpaid by AZUR shall promptly be refunded to AZUR or paid to
      INTELGENX, as applicable. In the event that any
      such audit reveals an underpayment by AZUR of more
      than five percent (5%), AZUR shall reimburse INTELGENX for the
      expense of such audit. Notwithstanding the
      foregoing, in the event that AZUR disagrees with the conclusions of any such audit, the Parties shall submit
      such dispute to the exclusive jurisdiction of the
      State of New York in accordance with Section 15.04 and no payment shall be made pursuant to this Section 5.11
      pending the outcome of such arbitration. As a
      condition to such audit, the independent public accountant selected shall execute a written agreement, reasonably
      satisfactory in form and substance to AZUR, to
      maintain in confidence all information obtained during the course of any such audit except for disclosure as necessary for
      the above purpose and all reasonable documents
      will be delivered to the auditor under these confidential terms. Additionally no auditor may be employed on
      a contingency basis.

      to make an announcement or public statement
      concerning the existence, subject matter or any term of this Agreement, or to disclose Confidential Information that the
      Disclosing Party is required to make or disclose
      pursuant to (a) a valid order of a court or Governmental Authority or (b) any other requirement of law or any securities

      Party becomes legally required to make such announcement, public statement or disclosure hereunder, the

      notice of such fact to enable the other Party to seek a protective order or other appropriate remedy concerning any
      such announcement, public statement or disclosure,
      including confidential treatment and/or appropriate redactions. The Disclosing Party shall fully co-operate with
      the other Party in connection with that other
      Partys efforts to obtain any such order or other remedy. If any such order or other remedy does not fully preclude
      announcement, public statement or disclosure, the
      Disclosing Party shall make such announcement, public statement or
      disclosure only to the extent that the same is legally required.

      Majeure. A Party shall not be in default with
      respect to the terms of this Agreement because

      case having the effect of preventing or prohibiting a Party from
      performing its obligations hereunder. "Force Majeure" shall not include
      failure caused by a party's financial condition, negligence, increased
      costs, or other similar circumstances.
