         thereto.

(5)      RTIN, Mr. Curtis  Swanson and Mr. Stanley  Swanson hereby release MedEx

         or conditions of such agreements against any of the parties thereto.

(6)      With regard to the two existing Houston leases  ("Houston  Leases") for
         planned  pharmacy sites,  RTIN hereby assigns such leases to IT/IS, and
         IT/IS agrees to assume such leases,  unless the indemnity  below fails,
         in which event,  it can terminate the same. With respect to the Houston
         Leases,  Mr. Solow agrees to indemnify and hold  harmless  IT/IS in all
         respects from any expenses, liability or causes of action pertaining to
         the Houston  Leases (other than rent),  until IT/IS executes new leases
         at which time the indemnity and the hold harmless  shall expire.  IT/IS
         shall use its best efforts to expeditiously  execute such new leases to
         replace the Houston  Leases.  Further,  (a) Curtis  Swanson & Co. joins
         herein for the sole purpose of  consenting  to this  provision  and (b)
         MedEx and Pegasus hereby assign all rights in and to the Houston Leases
         to IT/IS.

         however,  that (a) Eric  Mutter  or  another  MedEx  designee  shall be

         modifications,  enhancements or improvements made to ZipScript,  by Mr.
         Elliott,  at the request of MedEx and/or  Pegasus  after the  Effective

         against,  any interest in any of the Metropolitan Service Areas granted

         relate to, or are in any way  connected  to the subject  matter of this
         Agreement.

(5)      The  MedEx/Pegasus  Released  Parties,  RTIN Released Parties and IT/IS
         Released  Parties  are  hereinafter  referred  to  collectively  as the
         "Released Parties."

(6)      Release of Unknown Claims.

         (a)      Each of the Parties  hereby  agrees,  represents  and warrants
         that the  Claims  released  herein are not  limited to Claims  that are
         known or disclosed as of this  Agreement,  and, in connection  with the
         subject matter of the releases contained in this Agreement, each of the
         Parties  hereby  waives any and all rights and benefits that he, she or
         it now has or in the future may have  conferred  upon him, her or it by
         virtue of the provisions of law of any jurisdiction  that may now exist
         or  hereafter  be enacted and that may be  applicable  to the Claims so
         released in this  Agreement.  In this  connection,  each of the Parties
         hereby  agrees,  represents  and warrants  that he, she or it realizes,
         acknowledges  and agrees to assume the risk,  that  actual  matters now
         unknown, unanticipated or misunderstood by him, her or it in connection
         with the subject  matter of the Claims in this Agreement may have given
         or hereafter give rise to Claims or defenses, liabilities, obligations,
         demands, debts, controversies, damages, costs, losses and expenses that
         are presently  unknown,  unanticipated,  unsuspected or  misunderstood,
         which are Claims, and further agrees,  represents and warrants that the
         releases  in this  Agreement  have been  negotiated  and agreed upon in
         light of that  realization and that he, she or it nevertheless  intends
         to release,  discharge  and acquit all  Released  Parties from any such
         Claims  whether  unknown  causes of  action,  claims,  demands,  debts,
         controversies,  damages, costs, losses and expenses,  which are Claims,
         that in any way are related to the subject matter of this Agreement.

         (b)      Each of the Parties further  acknowledges  that after the date
         of this  Agreement,  the only Claims that he, she or it could  possibly
         have against any Released  Party with respect to the subject  matter of
         this Agreement would be those arising under this Agreement,  or conduct
         arising by virtue of a breach of this  Agreement or any matter  arising
         after the date of this Agreement.

         (c)      To the extent  (if any) to which such laws may be  applicable,
         each of the Parties  hereby waives and releases (to the maximum  extent
         permitted  by law) any claims,  rights or defenses  which he, she or it
         might otherwise have under any other law of any applicable jurisdiction
         that might limit or restrict the effectiveness or scope of the releases
         granted herein, or the rights of the Released Parties hereunder.



(7)      No Lawsuits.  None of the Parties  shall  institute  or  prosecute  any
         action or suit,  whether of a civil or  criminal  nature,  against  any
         Released Party in order to collect, enforce, declare, assert, establish
         or  otherwise  raise  any  Claim  which is  within  the  scope of those
         released  hereunder.  The releases  contained in this  Agreement  shall
         constitute a complete defense to any Claim released hereunder.

(8)      No Admission  of  Liability.  This  Agreement is not, and should not be
         construed  as,  an  admission  of  liability  by any Party to any other
         Party. Neither this Agreement,  nor the fact that a settlement has been
         reached  with  respect to any Claim,  nor the  consideration  exchanged
         herein,  shall be  admissible  into  evidence  against  any Party as an
         admission of any liability or fault.  Notwithstanding  the  immediately
         preceding sentence,  this Agreement,  if otherwise  admissible,  may be
         introduced into evidence at any proceeding between or among the Parties
         to enforce its terms.

F.       MISCELLANEOUS

(1)      Amendments;  Waivers. This Agreement may be modified or amended only by
         an  instrument  in writing  signed by all of the  Parties  hereto.  The
         waiver by any Party  hereto of a breach by any other  Party of any term
         or provision in this Agreement shall not operate as, or be construed as
         a waiver of, a  subsequent  or  continuing  breach by that Party of the
         same or any similar  provision of this Agreement.  The delay or failure
         of  a  Party  to  transmit  any  written  notice  hereunder  shall  not
         constitute a waiver by that Party of any default hereunder or any other
         or further default under this Agreement.

(2)      Headings. Headings have been inserted for convenience of reference only
         and do not constitute a part of this Agreement.

(3)      Interpretation. Neither this Agreement nor any uncertainty or ambiguity
         herein  shall be  construed  or  resolved  against  any of the  Parties
         hereto,  whether under any rule of  construction  or otherwise.  On the
         contrary,  this Agreement has been reviewed by all Parties and shall be
         construed  and  interpreted  according to the  ordinary  meaning of the
         words used so as to fairly  accomplish  the purposes and  intentions of
         all Parties hereto.

(4)      Entire Agreement. This Agreement and the schedules and exhibits thereto
         constitute the entire  agreement of the Parties and shall supercede any
         and all prior  agreements  with respect to the subject  matter  hereto,
         including,  without limitation,  the Stock Purchase Agreement,  and all
         such predecessor and successor agreements ancillary or related thereto,
         and the RTIN/Carr Agreement.

(5)      No Third Party  Beneficiaries.  Nothing herein  expressed or implied is
         intended  or shall be  construed  to confer upon or give to any person,
         other than the  Parties  hereto  and their  respective  successors  and
         permitted  assigns,  any rights or remedies  under or by reason of this
         Agreement.



(6)      No  Disparagement.  The Parties hereto agree to refrain from making any
         written or verbal disparaging  statements to third parties,  concerning
         any of the other Parties to this Agreement.

(7)      Severability.  If any provision of this  Agreement is prohibited by law
         or is otherwise determined to be invalid or unenforceable by a court of
         competent jurisdiction, such provision shall not affect the validity of
         the remaining provisions of this Agreement.

(8)      All Parties hereto  represent that they (a) are authorized to sign this
         Agreement, (b) if a corporation, are in good standing and (c) have full
         authority to perform all terms herein.
