                               "TRUST CERTIFICATE

          This is to certify that the undersigned Trustee has received a
     certificate or certificates issued in the name of
     __________________________________, evidencing the ownership of __________
     Shares of La-Man Corporation, a Nevada corporation, and that the Shares are
     held subject to all the terms and conditions of that certain Voting Trust
     Agreement dated May 19, 1998 between J. Melvin Stewart, as Trustee, and
     certain shareholders of La-Man Corporation. During the period of 10 years
     from and after May 19,1998, the Trustee, or his successors, as provided in
     the Voting Trust Agreement, shall possess and be entitled to exercise the
     right to vote and otherwise represent all of the Shares for all purposes,
     it being agreed that no voting right shall pass to the holder by virtue of
     the ownership of this certificate.

          This certificate is assignable with the right of issuance of a new
     certificate of like tenor only on the surrender to the undersigned or his
     successor of this certificate, properly endorsed. On the termination of the
     trust this certificate shall be surrendered to the trustee by the holder on
     delivery to that holder of a stock certificate representing a like number
     of Shares.

          In witness whereof, the undersigned Trustee has executed this
     certificate on May ________, 1998.

                                    J. Melvin Stewart, Trustee"

     The Trustee shall keep a record of the holders of the voting trust
certificates, including the names and addresses of the holders and the class of
Shares in respect of which the trust certificates are issued.  A copy of the
record shall be deposited by the Trustee with the Company at its registered
office.

     (S)5.  Transfer of Certificates.  Trust certificates, subject to the
            ------------------------                                     
conditions of this Agreement, may be transferred by endorsement by the person to
whom issued, or by his or her attorney in fact, or by the personal
representative or guardian of his or her estate, and delivery to the Trustee;
but the transfer shall not be evidence to or be binding on the Trustee until the
certificate is surrendered to him and the transfer is so entered in his Trust
Certificate Book, which shall be kept to show the names of the parties by whom
and to whom transferred, the numbers of the certificates, the number of Shares
and the date of transfer.  No new trust certificate shall be issued until its
predecessor certificate shall have been surrendered to and canceled by the
Trustee, and he shall preserve the certificates so canceled as vouchers.  In
case any trust certificate shall be claimed to be lost or destroyed, a new trust
certificate may be issued on such proof of loss and such security as may be
required by the Trustee.
