         The  Founders  acknowledge  that they must  bear the  economic  risk of

acquiring the RTIN Common Stock for their own account,  for investment,  and not
with a view to any  "distribution"  within the  meaning of the  Securities  Act.
Neither Mr. Solow nor Ms. Rau has any present  intention to make any transfer of
the RTIN Common Stock. The Founders agree that the RTIN Common Stock will not be
sold without  registration  under the Securities  Act and any  applicable  state
securities laws or an exemption therefrom.

3.24     RESTRICTIONS ON TRANSFERABILITY

         Mr.  Solow and Ms. Rau each  understand  that  because  the RTIN Common
Stock has not been  registered  under the Securities Act, they cannot dispose of
any  or all of the  RTIN  Common  Stock  unless  such  shares  are  subsequently
registered  under  the  Securities  Act  or  exemptions  from  registration  are
available.  Mr. Solow and Ms. Rau each acknowledge and understand that they have
no registration  rights. By reason of these restrictions,  Mr. Solow and Ms. Rau
each  understand  that they may be required to hold the RTIN Common Stock for an
indefinite  period of time.  Mr.  Solow and Ms.  Rau each agree that in no event
will they make a transfer or  disposition of any of the RTIN Common Stock unless
and until,  if requested by Buyer,  at the expense of Mr. Solow,  Ms. Rau or the
transferee,  as the case may be,  they  shall  have  furnished  to the  Buyer an
opinion of counsel or other  evidence,  reasonably  satisfactory to Buyer to the
effect that such transfer may be made without  registration under the Securities
Act. Mr. Solow and Ms. Rau each  understand that each  certificate  representing
the RTIN Common Stock will bear the following legend substantially as follows:

         THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  HAVE  NOT BEEN
         REGISTERED  UNDER THE  SECURITIES  ACT OF 1933 (THE "ACT") AND

         144 UNDER THE ACT.  THE SHARES  MAY NOT BE  OFFERED  FOR SALE,
         SOLD OR OTHERWISE  TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION  STATEMENT  UNDER  THE  ACT,  OR  PURSUANT  TO AN
         EXEMPTION FROM REGISTRATION UNDER THE ACT, THE AVAILABILITY OF
         WHICH IS TO BE ESTABLISHED TO THE SATISFACTION OF THE COMPANY.

Party has agreed, in writing, to pay such fees or expenses; (B) the Indemnifying
Party shall have  failed to assume the defense of such claim and employ  counsel
reasonably  satisfactory to such Indemnified  Party; or (C) based upon advice of
counsel to such Indemnified Party, there shall be one or more defenses available
to such Indemnified  Party that are not available to the  Indemnifying  Party or
there  shall  exist  conflicts  of  interest  pursuant  to  applicable  rules of
professional  conduct between such Indemnified Party and the Indemnifying  Party
(in which case, if the  Indemnified  Party  notifies the  Indemnifying  Party in
writing that such  Indemnified  Party elects to employ  separate  counsel at the
expense of the Indemnifying  Party,  the  Indemnifying  Party shall not have the
right to assume the defense of such claim on behalf of such Indemnified  Party),
in each of which events the fees and  expenses of such  counsel  shall be at the
expense of the Indemnifying Party. The Indemnifying Party will not be subject to
any liability for any settlement made without its consent (but such consent will
not be  unreasonably  withheld  or  delayed),  but if settled  with its  written
consent,  or if there be a final judgment  against the Indemnified  party in any
such action or  proceeding,  the  Indemnifying  Party shall  indemnify  and hold
harmless the Indemnified  Parties from and against any loss or liability (to the
extent stated above) by reason of such  settlement or judgment.  No  Indemnified
Party will be  required  to consent to entry of any  judgment  or enter into any
settlement that does not include as an unconditional  term thereof the giving by
the  claimant  or  plaintiff  to such  Indemnified  Party of a release  from all
liability in respect to such claim or litigation.

6.3      PAYMENT OF DAMAGES

         Any   Damages   for  which  an   Indemnified   Party  is   entitled  to
indemnification  under this Article 6 shall be paid by the Indemnifying Party to
the Indemnified Party as such Damages are incurred.

shall be  returned  to Buyer  within  three (3)  business  days of said  written
election  or  demand,  and  whereby  Buyer  shall  be  required  to  return  all
certificates  representing the MedEx Stock and the Pegasus Stock issued to Buyer

permitted retain as liquidated damages any capital  contributions made by Buyer,
which shall not include (i) the  Inter-Company  Loan or (ii) the  principal  and
accrued  interest under the October 25th  Pharmaceutical  Note as of the date of
the Closing.  In the absence of fraud,  the provisions of this Section 7.2 shall
be the Sellers'  sole and  exclusive  remedy for any failure of Buyer to perform
its obligations under Sections 5.1 and 5.2.

                                    ARTICLE 8

         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 of this  Agreement  shall not
operate as, or be construed to be a waiver of, a subsequent breach by that party
of the same or any similar or other  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 of any  other or  further
default under this Agreement.

8.2      SURVIVAL; BINDING NATURE

         All  representations  of the parties made in this  Agreement and in the
certificates,  exhibits,  schedules or other  written  information  delivered or
furnished  by one party to the other in  connection  with  this  Agreement  will
survive the Closing for a period equal to eighteen (18) months from the Closing.
All covenants and agreements  made in this  Agreement  will survive  Closing and
will bind and inure to the  benefit of the parties  hereto and their  respective
successors and assigns.

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

8.4      GOVERNING LAW; VENUE

         The parties agree and stipulate this Agreement shall be governed by and
controlled  by the laws of the  State of  Texas,  without  giving  effect to the

actions  arising out of this Agreement as well as the documents  contemplated by
this Agreement shall be brought in Harrison County, Texas.

8.5      NOTICES AND DEMANDS

overnight delivery or telecopy providing confirmation or receipt of delivery; or
(iii) three (3) days after being sent by certified or registered  mail,  postage
and charges prepaid,  return receipt  requested to the addresses as shown on the
signature pages of this Agreement or at any other address  designated in writing
to the other parties hereto.

8.6      SEVERABILITY

         If any  provision of this  Agreement is held invalid  under  applicable
law, such provision will be deemed ineffective to the extent of such invalidity,
and such invalid  provision will be modified to the extent  necessary to make it
valid and enforceable.  Any such invalidity will not invalidate the remainder of
this Agreement.

8.7      INTERPRETATION

         Neither this Agreement nor any uncertainty or ambiguity herein shall be
construed  or  resolved  against  Buyer or  Sellers,  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.

8.8      COUNTERPARTS; TELEFACSIMILE EXECUTION

         This  Agreement  may be executed in any number of  counterparts  and by
different  parties on separate  counterparts,  each of which,  when executed and
delivered,  shall be deemed to be an  original,  and all of  which,  when  taken
together,  shall  constitute  but one and the  same  Agreement.  Delivery  of an
executed  counterpart  of this  Agreement by  telefacsimile  shall be equally as
effective as delivery of a manually executed counterpart of this Agreement.  Any


                                       27


party delivering an executed counterpart of this Agreement by telefacsimile also
shall deliver a manually executed counterpart of this Agreement, but the failure
to  deliver a manually  executed  counterpart  shall not  affect  the  validity,
enforceability and binding effect of this Agreement.

8.9      ENTIRE AGREEMENT

         This Agreement and the exhibits to this Agreement constitute the entire
agreement of the parties, and except as specifically provided in this Agreement,
shall supersede any prior agreements,  including, without limitation, the Letter
Agreement.

gender where appropriate.

8.11     PUBLICITY

         No party shall make any publicity  release or  announcement  concerning
this Agreement or the transactions contemplated hereby without the prior written
approval thereof by the other parties, as the case may be, except as required by
applicable  law, in which case the party  issuing the release will so advise the
other  parties in writing  and submit a copy of such  release in advance of such
issuance.

8.12     NO THIRD PARTY BENEFICIARIES

         Except  as set forth in  Section  8.13,  nothing  herein  expressed  or
implied is intended or shall be  construed to confer upon or give to any person,

assigns, any rights or remedies under or by reason of this Agreement.

8.13     SEPARATE COUNSEL

         Buyer  acknowledges  and agrees  that with  respect  to the  agreements
contained in this Agreement,  each such party is relying solely on its own legal
counsel  and  not on any  advice,  statements  or  representations  of  Sellers'
counsel, Locke Liddell & Sapp LLP.
