Note.

     IT IS THEREFORE AGREED:

     1.         Transfer of Shares to Trustee.  Shareholder, simultaneously

     2.         Pledge of Shares.  Trustee and Shareholder each acknowledge 
and agree that all of the shares of stock of Surrey owned of record or
beneficially by Shareholder and all of the shares of stock evidenced by such
new share certificates issued in the name of the Trustee are encumbered and

     4.         Transfer at Termination.  At the termination of the trust hereby
created, the Trustee shall deliver to Surrey and to Bank notification of the
termination of this Agreement.

     5.         Copies of Agreement.  This Agreement may be executed in multiple

of this Agreement and the establishment of this trust, Trustee shall cause a

     8.         Severability of Provisions.  This Agreement shall not be 
severable or divisible in any way, but it is specifically agreed that,
if any provision should be invalid, the invalidity shall not effect the
validity of the remainder of the Agreement.

     9.         Construction by Trustee.  The Trustee is authorized and 
empowered to construe this Agreement.  Trustee's reasonable
construction made in good faith shall be conclusive and binding on Shareholder
and on all parties to this Agreement.

Surrey subject to this Agreement shall be subject to adjustment as a
result of any stock splits, combinations or dividends payable by Surrey in
shares of common stock.  All such shares including any increase in the number
of shares, shall at all times, however, remain encumbered by the lien of Bank.

                   purchaser at the price for which the Shareholder has
                   received a bona fide offer.  If the Corporation does not
                   purchase or find a purchaser within the sixty-day (60)
                   period at said price, the Shareholder shall be free to
