     Section 7.1.2, W-L will have the rights and responsibilities of the
     iInventori as described in this Section 7 in respect of any such
     patentable, jointly owned Proprietary Technology and RPI shall have the
     rights and responsibilities of a non-Inventor therein.  With regard to
     Ribozyme Technology, RPI shall have the rights and responsibilities of the
     iInventori as described in this Section 7 in respect of any such
     patentable, jointly owned Proprietary Technology and W-L shall have the
     rights and responsibilities of a non-Inventor therein.  The party granted
     the rights and responsibilities of iInventori hereunder shall use patent
     counsel reasonably acceptable to the non-Inventor and shall pay all
     expenses in connection with its preparation, filing, and prosecution of
     patent applications that claim patentable, jointly owned Proprietary
     Technology. All expenses in connection with the preparation, filing and
     prosecution of patent applications that claim Inventions shall be borne by
     the party deemed to be the Inventor or granted the rights and
     responsibilities of the Inventor.

7.3. Patent Filing, Prosecution, Maintenance and Counsel.
     --------------------------------------------------- 

        7.3.1  The Inventor shall prepare, prosecute, and maintain (and shall
               keep the other party currently informed of all steps to be taken
               in such preparation, prosecution and maintenance of all of its
               Patent Rights which claim an Invention and at the other partyis
               request, shall furnish the other party with copies of such Patent
               Rights and other related correspondence relating to such
               Invention to and from patent offices and permit the other party
               to offer its comments thereon before the Inventor makes a
               submission to a patent office which could materially affect the
               scope or validity of the patent coverage that may result. The
               non-Inventor party shall offer-its

               this Section 7 or (ii) protect against abandonment of a Patent
               Right which claims an Invention, the Inventor shall permit the
               non-Inventor party, at its option and expense, to undertake such
               obligations. The party not undertaking such actions shall fully
               cooperate with the other party and shall provide to the other
               party whatever assignments and other documents that may be needed
               in connection therewith. The party not undertaking such actions
               may require a suitable indemnity against all damages, costs and
               expenses and impose such other reasonable conditions as such
               partyis advisors may require. If a party undertakes the
               obligations of iInventori under this Section 7 with respect to
               any Patent Rights of the other party under this Section 7.3.2, it
               shall prosecute and maintain the same vigorously at its own
               expense, and shall not abandon or compromise them or fail to
               exercise any rights of appeal without giving the other party the
               right to take over the prosecuting partyis conduct, at such other
               partyis own expense.

          requirement of law, including with out limitation, disclosures
          required by the US Securities Exchange Commission,, provided that such
          Party has complied with the provisions set forth in paragraph 8.4.

8.4  If the receiving Party or any of its affiliates becomes legally required
     to disclose any Confidential Information, the receiving Party shall give
     the other Party to this Agreement prompt notice of such fact so that such
     Party may obtain a protective order or other appropriate remedy concerning
     any such disclosure and/or waive compliance with the non-disclosure
     provisions of this Agreement. The receiving Party and its Affiliates will
     fully cooperate with the other Party to this Agreement in connection with
     such Party's efforts to obtain any such order or other remedy. If any such
     order or other remedy does not fully preclude disclosure or the other Party
     to this Agreement waives such compliance, the receiving Party and its
     affiliates will make such disclosure only to the extent that such
     disclosure is legally required and will use its best efforts to have
     confidential treatment accorded to the disclosed Confidential Information.

8.5  Term.  The obligations of RPI and W-L under this Section 8 shall continue
     ----                                                                     
     for a period of 10 years after the expiration or termination of this
     Agreement, whichever is the later.
