          WHEREAS,  the parties hereto have entered into that certain Employment

          NOW,  THEREFORE,  in  consideration  of the  mutual  covenants  herein
contained  and  other  good and  valuable  consideration,  the  Company  and the
Executive hereby agree as follows:

          1.   Definitions.   Unless  defined   elsewhere  in  this   Agreement,
capitalized  terms  contained  herein  shall  have  the  meanings  set  forth or
incorporated by reference in Section 17 of the Employment Agreement.

          2. Non-competition; Non-solicitation.

          (a) In  consideration of the Stock Purchase  Agreement,  the Executive
agrees that for the period ending on the fifth anniversary of the Stock Purchase
Agreement or for such longer  period of time if the Executive is employed by the
Company  in  accordance  with  Section  3(b) of the  Employment  Agreement  (the
"Non-Competition  Period"),  the  Executive  will not,  directly  or  indirectly
(whether  as a sole  proprietor,  partner or  venturer,  stockholder,  director,
officer, employee,  consultant or in any other capacity as principal or agent or
through any Person, subsidiary or employee acting as nominee or agent):

               (i) conduct or engage in or be interested  in or associated  with
     any Person which conducts or engages in the AHM Business  within the United
     States;

               (ii) take  any  action,   directly  or  indirectly,  to  finance,
     guarantee or provide any other material assistance to any Person engaged in
     the AHM Business;

               (iii)  solicit,  contact  or  accept  business  of any  client or
     counterparty  whom the Company  served or conducted  business with or whose
     name became known to the  Executive as a potential  client or  counterparty
     while in the employ of the Company or during the Non-Competition Period; or

               (iv) influence  or  attempt  to  influence any  Person  that is a
     contracting  party with the Company at any time during the  Non-Competition
     Period to terminate any written or oral agreement with the Company.

          For purposes of this Agreement, the term "AHM Business" shall mean the
residential  mortgage  lending or  residential  mortgage  brokerage  business as
conducted  by the  Company  and any  business  involving  the supply of services
substantially  similar to  services  provided  by the Company at the time of the
termination of the Executive's employment.

          (b) The Executive  shall not,  whether for the Executive's own account
or in conjunction with or on behalf of any other Person,  solicit or entice away
from the  Company  any  officer,  employee  or  customer  of the  Company or the
Subsidiary  during  the term of the  Non-Competition  Period nor  engage,  hire,
employ, or induce the employment of any such Person whether or not such officer,
employee  or  customer  would  commit a breach of  contract by reason of leaving
service or transferring business.

          (c) The restrictive provisions hereof shall not prohibit the Executive
from (i) having an equity  interest in the  securities of any entity  engaged in
the AHM Business or any business  with respect to which the  Executive  obtained
confidential or proprietary data or information,  which entity's  securities are
listed on a  nationally-recognized  securities  exchange or quotation  system or
traded in the over-the-counter market, to the extent that such interest does not
exceed 5% of the  outstanding  equity  interests of such entity or (ii) with the
prior written consent of the Company,  serving as a director or other advisor to
any other Person.

          (d) The Executive agrees that the covenants  contained in this Section
are reasonable covenants under the circumstances,  and further agrees that if in
the  opinion  of a  court  of  competent  jurisdiction,  such  restraint  is not
reasonable in any respect,  such court shall have the right, power and authority
to excise or modify such provision or provisions of these  covenants which as to
such court shall appear not reasonable  and to enforce the remainder  thereof as
so amended.

          (e)  Notwithstanding  anything herein to the contrary,  if the Company
shall  terminate the  Executive's  employment  during the term of the Employment
Agreement other than pursuant to Section 7(b) of the Employment  Agreement,  the
Executive shall be subject to restrictions set forth in this Agreement until the
earlier  of two  years  from  the  Date  of  Termination  or  expiration  of the
Non-Competition  Period, unless grounds exist at such time that would permit the
Executive to terminate his  employment for Good Reason under Section 7(c) of the
Employment  Agreement,  in which case the Executive shall only be subject to the
restrictions in this Agreement until the earlier of nine months from the Date of
Termination or the expiration of the Non-Competition Period.

          (f) Notwithstanding  anything herein to the contrary, if the Executive
shall  terminate the  Executive's  employment  during the term of the Employment
Agreement for Good Reason pursuant to Section 7(c) of the Employment  Agreement,
the Executive shall be subject to restrictions set forth in this Agreement until
the earlier of nine months from the Date of Termination or the expiration of the
Non-Competition Period.

          (g)   Notwithstanding   anything  herein  to  the  contrary,   if  the
Executive's  employment  terminates under any circumstance that does not entitle
the  Executive  to  payments  under  Section  8(a) of the  Employment  Agreement
(including a termination  by reason of the death or Disability of the Executive,
or by reason of the Company or the  Executive  electing not to extend or further
extend the term of this Agreement pursuant to Section 3(b)), the Executive shall
be subject to the  restrictions set forth in this Agreement until the expiration
of the Non-Competition Period.
