        THIS AGREEMENT made as of the 30th day of April, 1997, is made

BETWEEN

        MERCRISTO DEVELOPMENTS, INC.

        (hereinafter called "MDI")

AND

        EGYPTIAN ARABIANS INC.

        (hereinafter called "EAI")

AND

        RESI CORP.

        (hereinafter called "RESI")


WHEREAS it is intended that pursuant to an agreement of purchase and sale dated
as of April 10, 1997 between E.S.I. Holdings Limited ("Holdings") and E.S.I.
Securities Inc. ("Securities"), Holdings will agree to sell and Securities will
agree to purchase certain land known municipally as 240 Argyle Avenue, Ottawa,
Ontario (the "Land") on the terms and conditions as set out in the agreement of
purchase and sale (the "Securities Transaction");

AND WHEREAS it is intended that pursuant to an agreement of purchase and sale
dated as of April 10, 1997 between Securities and 622291 Ontario Limited
("622291"), Securities will agree to sell and 622291 will agree to purchase the
Land on the terms and conditions as set out in the agreement of purchase and
sale (the "622291 Transaction");

AND WHEREAS it is intended that the Securities Transaction and the 622291
Transaction shall take place prior to (i) the sale of shares in the capital
stock of 622291 from David Edwards, Patricia Edwards and The Edwards Children's
Trust to RESI and from RESI to EAI (the "Edwards Reorganization") and (ii) the
sale of shares in the capital stock of EAI from RESI to MDI pursuant to an
Agreement and Plan of Reorganization dated as of April 30, 1997 among MDI, EAI
and RESI (the "Mercristo Transaction");

AND WHEREAS it is intended that the Mercristo Transaction shall close in escrow
pending fulfillment of the following conditions: acceptance of the common shares
in the capital stock of MDI for trading on NASDAQ; registration of MDI Common
Stock with the Securities

 
Exchange Commission; and any other conditions as may be agreed to between the
parties (the "Escrow Conditions:);

AND WHEREAS it is intended that the Securities Transaction, the 622291
Transaction, the Edwards Reorganization and the Mercristo Transaction are
interrelated and that the parties intend that no Transaction shall be finally
completed unless all Transactions are finally completed;

NOW THEREFORE in consideration of the premises and of the covenants contained
herein, the sum of $1 paid by each of the parties to the other parties hereto
and other good and valuable consideration (the receipt and sufficiency of which
are hereby acknowledged), the parties hereto agree as follows:

1.  The Mercristo Transaction shall close in escrow effective April 30, 1997,
pending satisfaction of the parties that the Escrow Conditions will be
fulfilled.  Until such time, it is the intention of the parties that all
documentation and payments relating to the Mercristo Transaction shall not be
delivered to the other parties entitled thereto but shall remain in the
possession of the attorneys for MDI, Harter, Secrest & Emery (the "Escrow
Agent").  The parties agree that if they are satisfied that the Escrow
Conditions will be fulfilled, they shall provide a joint written direction to
the Escrow Agent that all documentation and payments relating to the Mercristo
Transaction shall be delivered to the parties entitled thereto so that the
escrow shall be lifted and the Mercristo Transaction shall be finally closed.
The parties agree that if they are not satisfied that the Escrow Conditions will
be fulfilled, they shall provide a joint written direction to the Escrow Agent
that all documentation and payments relating to the Mercristo Transaction be
returned to the parties who executed the same so that the Mercristo Transaction
shall be null and void.  Until such time as the written direction to the Escrow
Agent shall be made, RESI shall not be deemed to have delivered any shares of
EAI to MDI and MDI shall not be deemed to have issued any shares of MDI to RESI.

2.  The parties hereto agree that each shall with reasonable diligence proceed
to take all action to do all things and provide reasonable assurances as may be
required to consummate the transaction contemplated herein, and the parties
agree to provide such further documents or instructions required by the other
parties as may be necessary to effect the purpose of this Agreement and carry
out its provisions, whether prior to or after closing.

3.  This Agreement will be governed by the laws of the State of Delaware.

4.  This Agreement represents the entire understanding of the parties and no
modifications thereof or additions thereto will be binding unless in writing,
having direct reference to this Agreement and executed by all the parties.

5.  This Agreement shall enure to the benefit of and be binding upon the parties
hereto, their successors and assigns.
