Lender, with interest to accrue thereon according to the terms and conditions of
this Note. Lender shall provide Borrower with an updated Schedule of amounts due

         F. Borrower shall make payments on this Note as follows:

            1. For the period from the date hereof through July 31, 2000
               Borrower shall pay accrued interest on the unpaid principal
               amount outstanding (calculated as aforesaid) quarterly on each
               November 1, February 1, May 1 and August 1.

            2. One-half of the then unpaid principal amount of this Note shall
               be due and payable on August 1, 1999 and any remaining unpaid
               principal amount under this Note shall be due and payable on
               August 1, 2000.

unpaid principal amount of this Note and/or any accrued and unpaid interest
hereon at any time during the term of this Note at the rate of one share of
common stock of the Lender for each Three-quarters of one cent ($.0075) of the
aforesaid principal and/or interest elected to be converted. The Lender shall
make the election by giving written notice to the Borrower, specifying the
dollar amount of principal and/or interest to be converted. Upon receipt of the
written notice by Lender, all principal and/or interest specified in such
written notice shall be deemed converted into such shares of common stock, and
the Borrower's obligation under this Note, to the extent so converted, shall
cease to be outstanding.

         H. The parties agree that the Borrower shall not dilute any of the
existing stock or issue new stock of MURRAY UNITED DEVELOPMENT CORPORATION
without the written permission of the Lender.

         I. The Lender is authorized to endorse the date and principal amount of
each Disbursement made to or on behalf of Borrower, and each payment of
principal and/or interest with respect thereto on the Schedule hereto, which
endorsement shall constitute prima facie evidence of the accuracy of the
information endorsed.

         J. The occurrence of any of the following events shall constitute an
event of default hereunder, which shall cause the entire unpaid balance of this
Note, and accrued interest, to become immediately due and payable without
requiring the Lender to make a demand on the Borrower:

            1. If Borrower shall default in the performance of any obligation of
               the Borrower, including but not limited to the payment of
               principal and/or interest due upon the Note, for a period of
               fifteen (15) days after the due date thereof and Lender provides
               written notice of such default to Borrower;

            2. If Borrower voluntarily suspends the operation of its business;

            3. If Borrower makes an assignment for the benefit of its creditors;

            4. If Borrower files a voluntary petition under the United States
               Bankruptcy Code, as amended, or any other federal or state
               insolvency law, or applies for or consents to the appointment of
               a receiver, trustee or custodian of all or part of its property;

            5. If Borrower shall submit and file an answer admitting to the
               jurisdiction of the Court and material allegations of an
               involuntary petition filed against it under the Bankruptcy code,
               as amended, or any other federal or state insolvency law, or
               fails to have such petition dismissed within 45 days after its
               filing;

            6. If an order of relief is entered into following the filing of an
               involuntary petition against the Borrower under the United States
               Bankruptcy Code, as amended, or any other federal or state
               insolvency law, or if an order shall be entered appointing a
               trustee, receiver or custodian of all or part of Borrower's
               property;

            7. Upon the sale of all or a substantial amount of the assets of
               Borrower.

Failure to exercise any of Lender's rights hereunder shall not constitute a
waiver of the rights to exercise same in the event of any subsequent default.

         K. Borrower shall reimburse Lender, upon demand, for all costs and
expenses incurred in connection with the collection and/or enforcement of this
Note, including but not limited to reasonable attorney fees and expenses,
whether or not a law suit is actually commenced.

         L. Lender agrees that the indebtedness evidenced by this Note is
subordinated in right of payment to the prior payment in full of indebtedness of
the Borrower to any lender of funds to Borrower if the terms of documentation
evidencing any such loan expressly provide that such funds are senior in right
of payment to any other borrowed funds of the Borrower ("Senior Indebtedness") ,
and agrees that such subordination is for the benefit of the holder of the
Senior Indebtedness; provided, however, that this Note shall be senior in right
of payment to any other unsecured indebtedness (other than for borrowed money)
of the Borrower, including, but not limited to trade payables.

         M. In the event that any payment shall be due on a Saturday, Sunday or
public holiday, the parties agree that said payment may be made the next
succeeding business day.

         N. The Parties agree that the Borrower has the right to prepay the
principal amount of this Note. If Borrower exercises this option, Borrower
agrees to pay 115% of the outstanding balance of the principal so repaid at that
time. If Borrower should exercise this option, Lender shall have the right to
exercise his option to convert any portion of the unpaid principal prior to
prepayment.

         0. No alteration, amendment or waiver of any provision of this Note
shall constitute a waiver of any other term hereof, or otherwise release or
discharge the liability of Borrower under this Note, unless the Lender shall
agree to such alteration, amendment or waiver in writing.

                                       3

         P. To the fullest extent permitted by law, Borrower hereby waives
presentment, demand for payment, notice of dishonor, notice of protest and all
other notices or demands of any kind with respect to this Note.

         Q. This Note may not be modified , terminated or discharged, nor shall
any waiver hereunder be effective, unless in writing signed by the party against
whom the same is asserted. This Note shall be construed in accordance with and
governed by the laws of the State of New York.

         R. If any term of this Note conflicts with law, the parties agree that
all other terms of this Note shall remain in effect without the conflicting
term. This means that any of the terms of the this Note that conflict with the
law may be separated from the remaining terms, and the remaining terms will
still be enforced.
