          (b)  Solicitation.   During   the   Employment   Term  and  two  years

               bond or other  security.  Nothing  herein  shall be  construed as

               breach or threatened breach.

     7.   Covenant Not to Compete.

          (a)  Non-Competition   Covenant.   In  return  for  the  consideration

               period of two years from the  termination of his employment  with
               Employer (the  "Non-Competition  Term") in any manner whatsoever,
               either  directly  or  indirectly,  with any  Person in each case,
               within the Geographic Area:

               (i)  provide or offer to  provide  to any  Person  any  services,
                    information or other assistance  relating to the business of
                    Employer  or of any of its  affiliates  (as of the  date  of
                    termination of Employee's employment) or with respect to any
                    customer,  client or  prospective
<PAGE>

                    or stockholder  of, or lender to, or in any other  capacity,
                    in each case, any real estate, timeshare product, service or
                    product,  or other  which is the same  as,  similar  to,  or
                    competes  with  Employer  or  its  affiliate's  services  or
                    products or which compete with  Employer or its  affiliate's
                    business;

               (iii)(A) call on any Acquisition  Candidate with the knowledge of
                    such Acquisition Candidate's status as such, for the purpose
                    of  acquiring,   or  arranging  the   acquisition  of,  that
                    Acquisition  Candidate by any Person other than  Employer or
                    its affiliates, (B) induce any Person which is a customer of
                    Employer  or  its   affiliates  to  patronize  any  business
                    directly or  indirectly  in  competition  with the  business
                    conducted  by  Employer  or  its  affiliates;  (C)  canvass,
                    solicit  or accept  from any Person  which is a customer  of
                    Employer or its affiliates,  any such competitive  business;
                    or (D)  request or advise any Person  which is a customer of
                    Employer  or its  affiliates,  or its or  their  successors;
                    "Acquisition  Candidate" means (I) any Person engaged in the
                    Timeshare  Business,  or the purchase or development of real
                    estate  with  the  purpose  of  engaging  in  the  Timeshare
                    Business or (II) any project with  respect to the  Timeshare
                    Business,  and in either  case (i)  which  was  called on by
                    Employer or its affiliates,  in connection with the possible
                    acquisition  by Employer or its affiliates of that Person or
                    project,   or  (ii)  with  respect  which  Employer  or  its
                    affiliates has made an acquisition analysis; or

               (iv) directly  or  indirectly  employ,  or  knowingly  permit any
                    Person,  directly  or  indirectly,  controlled  by  him,  to
                    employ,  any  Person who was  employed  by  Employer  or its
                    affiliates at or within the prior six months.

          (b)  Employee  agrees and  understands  that  Employer's  business  is
               highly  competitive  and that Employer has invested  considerable
               sums of money in developing real estate and timeshare  properties
               and services,  training  programs,  sales  programs,  pricing and
               marketing  formulas  and  programs,  and account  records for the
               proper servicing of its clients and potential clients.

          (c)  Employee  further  agrees and  understands  that this covenant is
               necessary for the  protection  of Employer due to its  legitimate
               interest in protecting  its business  goodwill and Trade Secrets.
               Employee  further  agrees and  understands  that,  because of the
               legitimate  interest  of  Employer  in  protecting  its  business
               goodwill and Trade Secrets as well as the extensive  confidential
<PAGE>
               information  and special  knowledge  received  by  Employee  from
               Employer,  the  restrictions  enumerated  in Section 7(a) are not
               oppressive and are, in fact, reasonable. Employee also agrees and
               understands  that,  due to the necessity of this covenant and the
               adequate  consideration  supporting  it, this  covenant  does not
               prevent  competition,  and in fact,  it  encourages  Employer  to
               entrust Employee with Trade Secrets.

          (d)  If a court of competent jurisdiction determines that the scope of
               any  provision  of this  Section 7 is too broad to be enforced as
               written, the parties intended that the court reform the provision
               to such narrower  scope as it  determines  to be  reasonable  and
               enforceable.

          (e)  Employee  agrees that if he breaches this covenant he will submit
               to the rendition of a temporary  restraining order, without prior
               notice,  and thereafter to a temporary and permanent  injunction.
               Further,  Employee  agrees to the  jurisdiction of an appropriate
               court  in  Harris  County,  Texas,  for the  enforcement  of this
               covenant.
