 Dear Applicant:

        We have made a favorable  determination on your plan,  identified above,
 based on the  information  supplied.  Please keep this letter in your permanent
 records.

        Continued  qualification  of the plan under its present form will depend
 on its  effect in  operation.  (See  section  1.401-1(b)(3)  of the  Income Tax
 Regulations.) We will review the status of the plan in operation periodically.

 The enclosed document explains the significance of this favorable determination
 letter,  points out some features that may affect the qualified  status of your
 employee   retirement   plan,   and  provides   information  on  the  reporting
 requirements  for your plan. It also describes  some events that  automatically
 nullify it. It is very important that you read the publication.

        This letter  relates  only to the status of your plan under the Internal
 Revenue Code. It is not a  determination  regarding the effect of other federal
 or local statutes.

        This   determination  is  subject  to  your  adoption  of  the  proposed
 amendments  submitted  in your  letter  dated  March  27,  1996.  The  proposed
 amendments  should  be  adopted  on  or  before  the  date  prescribed  by  the
 regulations under Code section 401(b).

        'This  determination  is also  subject to your  adoption of the proposed
 amendments  submitted in your letter(s) dated February 16, 1996. These proposed
 amendments  should  also be  adopted on or before  the date  prescribed  by the
 regulations under Code Section 401(b).

        This determination  letter is applicable for the amendment(s) adopted on
October 1, 1988.

        This  plan   satisfies  the  minimum   coverage  and   nondiscrimination
 requirements  of sections  410(b) and  401(a)(4)  of the Code  because the plan
 (disregarding   any  portion  that  benefits  solely   collectively   bargained
 employees)  benefits no highly  compensated  employees.  This letter may not be
 relied on with respect to the  aforementioned  requirements of the Code for any
 plan year in which the plan  (disregarding  any portion  that  benefits  solely
 collectively bargained employees) benefits any highly compensated employees.

        This letter is issued under Rev. Proc. 9339 and considers the amendments
 required by the Tax Reform Act of 1986 except as otherwise specified in this 
 letter.

        This  letter may not be relied  upon with  respect  to whether  the plan
 satisfies  the  qualification  requirements  as  amended by the  Uruguay  Round
 Agreements Act, Pub. L.103-465.

        If you have questions concerning this matter,  please contact the person
 whose name and telephone number are shown above.

                                            Sincerely yours,

                                            /s/Paul M. Harrington
                                           -----------------------
