                  Obligation of confidentiality. Rather, you will be expected to
                  use only that information which is generally known and used by
                  persons with training and experience comparable to your own,
                  which is common knowledge in this industry or otherwise
                  legally in the public domain, or which is otherwise provided
                  or developed by the Company. During our discussions about your
                  job duties, you assured us that you would be able to perform

                  will devote your best efforts and attention to the business of
                  AlgoRx. The Company acknowledges and agrees, however, that
                  nothing in this letter shall be deemed to prevent you from

                  hereunder, provided the same: (i) do not materially interfere
                  with performance of your duties hereunder; and (ii) are not a
                  breach of any of the foregoing restrictions on confidential
                  information. The CEO may rescind his consent to these other
                  activities if he determines that such activities materially
                  compromise the Company's business interests.

            9.    TERMINATION: You may terminate your employment with AlgoRx at
                  any time and for any reason whatsoever simply by notifying

                  termination.

            10.   ENTIRE AGREEMENT: This letter, together with your Proprietary
                  Information and Inventions Agreement, forms the complete and
                  exclusive statement of your employment agreement with AlgoRx.
                  It supercedes any other agreements or promises made to you by
                  anyone, whether oral or written, and it can only be modified
                  in a written agreement signed by an officer of AlgoRx.
