Attn: Roy Israel, President

Re:  Leased dated September 13, 1995 between The 1010 Company, L.P., as Owner,
     and NAM Corporation, as Tenant, for premises located at 1010 Northern
     Boulevard, Great Neck, New York (as amended to date, the "Lease")

Dear Mr. Israel:

This letter will confirm our agreement concerning certain matters with respect
to the addition of Suite 311 (the "Additional Space") to your space:

     1. The "Additional Space Commencement Date" as referred to in Section 69.A.
of the Lease shall conclusively be deemed July 1, 2000, notwithstanding the fact
that it is not expected that Owner will achieve "Substantial Completion" (as
referred to in Section 69.A. of the Lease) within the Additional Space by such
date. Owner agrees, however, to commence and thereafter diligently prosecute to
completion work in the Additional Space in accordance with Section 69.C. of the
Lease promptly after the date (the "Construction Commencement Date"). Owner and
Tenant have approved the plans and specifications and anticipated costs for such
work (including Tenant's Written Authorization for Tenant Extras, if necessary)
and any governmental permits required have been obtained. If substantial
completion of the leasehold improvements in the Additional Space does not occur
within twenty (20) days of the Construction Commencement Date and such delay is
not the direct result of any act or omission of Tenant or its employees or
agents, of which prompt notice of such action shall be given to Tenant, then the
Additional Space Commencement Date shall be moved back by the same number of
days by which the date of Substantial Completion exceeds twenty (20) days from
the Construction Commencement Date.

     2. The "Termination Date" of the Lease as referred to in Section 69.A. of
the Lease (including the "Termination Date" for all space currently being leased
by Tenant) is hereby extended to June 30, 2005.

     3. Commencing the Additional Space Commencement Date, the total fixed
annual rental (exclusive of the Electric Charge set forth in Article 38 of the

(i.e., all space) shall be as follows:

        1. $261,640.20 ($28.815/sf) payable in equal monthly installments of
           $21,803.35 for the period commencing on July 1, 2000 and ending on
           October 31, 2000.

        a. $244,615.20 ($26.94/sf) payable in equal monthly installments of

     4. Commencing the Additional Space Commencement Date, (i) "Tenant's Share"
as defined in Article 40(B) of the Lease shall be increased from .0410 to .0588
and (ii) the floor area of the Premises as set forth in Article 40(B) of the
Lease shall be increased from 6,330 square feet to 9,080 square feet.
