THIS LEASE AMENDMENT ONE ("Amendment") is made and entered into as of the
10th day of November, 1999, by and between CMD REALTY INVESTMENT FUND II,
L.P., a(n) Illinois limited partnership ("Landlord"), and UNIVIEW
TECHNOLOGIES CORPORATION, a Texas corporation ("Tenant ").

     A.     Landlord and Tenant are the current parties to that certain
lease ("Original Lease") dated October 18, 1999, for premises
(the,"Premises") in the building (the "Building") known as Bent Tree
Green, located at 17300 North Dallas Parkway, Dallas, Texas (the
"Property ") (as amended herein, the "Lease").

     B.     Tenant has requested that additional space in the Property be
added to the Premises, and Landlord is willing to grant the same, on the
terms and conditions herein.

     NOW, THEREFORE, in consideration of the mutual covenants and
agreements herein contained, and other good and valuable consideration,
the parties do hereby agree as follows:

     1.      Additional Premises. The space adjacent to the original
Premises and known as a portion of the second floor (the "Additional
Premises"), the approximate location of which is shown on Exhibit A
hereto, and which shall be deemed to contain 801 square feet of rentable
area for purposes hereof, shall be added to and become a part of the
Premises, commencing on December 1, 1999 ("Additional Premises
Commencement Date"), and continuing co- terminously with the expiration
date under the Lease ("Lease Expiration Date"), as the same may be
extended from time to time, subject to the terms and conditions set forth
hereinafter.

     2.     Base Rent For Additional Premises. The base or minimum
monthly rent for the Additional Premises shall be as set forth in the
following schedule:

                    Period                                Additional Premises
                                                           Monthly Base Rent

Additional Premises Commencement Date - November 30, 2000      $ 1,335.00
December 1, 2000 - November 30, 2002                           $ 1,368.38
December 1, 2002 - Lease Expiration Date                       $ 1,401.75

     3.     Additional Rent; Tenant's Share. On the Additional Premises
Commencement Date, "Tenant's Share" of increases in Expenses and Taxes
shall be increased by 5786/10,000 percent (.5786%) with respect to the
Additional Premises, for a total of five and 9226/10,000 percent
(5.9226%) with respect to the entire Premises including the Additional
Premises.

     4.      Consolidated or Separate Billings. The minimum or base
rentals, real estate taxes, operating or other expenses of the Property,
and all other rentals and charges respecting the Additional Premises are
sometimes herein called the "Additional Premises Rent". Landlord may
compute and bill the Additional Premises Rent (or components thereof)
separately or treat the Additional Premises and Premises as one unit for
computation and billing purposes.
<PAGE>
     5.     Prorations. If the Additional Premises Commencement Date
occurs other than on the beginning of the applicable payment period under
the Lease, Tenant's obligations for base or minimum rentals, real estate
taxes, operating or other expenses of the Property and other such charges
shall be prorated on a per them basis.

     6.     Other Terms; Certain Provisions Deleted.       On the
Additional Premises Commencement Date, the Additional Premises shall be
added to the Premises under the Lease, and all terms and conditions then
or thereafter in effect under the Lease shall apply to the Additional
Premises, except as provided to the contrary herein.

     7.       Condition of Additional Premises.        Tenant has
inspected the Additional Premises (and portions of the Building,
Property, systems and equipment providing access to or serving the
Additional Premises) or has had an opportunity to do so, and agrees to
accept the same "AS IS" without any agreements, representations,
understandings or obligations on the part of Landlord to perform any
alterations, repairs or improvements, or regarding any other matter,
except for the Work referred to in Exhibit B attached hereto, with
respect to which the terms of Section B of Article 4 of the Original
Lease are incorporated herein.

     8.    Additional Premises Commencement Date Adjustments. The terms
of Sections B, C and D of Article 2 of the Original Lease are
incorporated herein with respect to the Additional remises.

     9.     Real Estate Brokers. Tenant represents and warrants that
Tenant has not dealt with any broker, agent or finder in connection with
this Amendment, except Jackson & Cooksey, and agrees to indemnify and
hold Landlord, and it employees, agents and affiliates harmless from all
damages, judgments, liabilities and expenses (including reasonable
attorneys' fees) arising from any claims or demands of any broker, agent
or finder with whom Tenant has dealt for any commission or fee alleged to
be due in connection with this Amendment.

     10.    Guarantors. This Amendment shall be of no force or effect
unless and until accepted by any guarantors of the Lease, who by signing
below shall further confirm that their guarantee shall apply to the Lease
as amended herein, unless such requirement is waived by Landlord in
writing.

     11.    Offer. The submission and negotiation of this Amendment shall
not be deemed an offer to enter into the same by Landlord. Tenant's
execution of this Amendment constitutes a firm offer to enter into the
same which may not be withdrawn for a period of fifteen (15) days after
delivery to Landlord. During such period, Landlord may proceed in
reliance thereon and permit Tenant to enter the Additional Premises, but
such acts shall not be deemed an acceptance. Such acceptance shall be
evidenced only by Landlord signing and delivering this Amendment to
Tenant.

     12.    Whole Amendment; Full Force and Effect; Conflicts. This
Amendment sets forth the entire agreement between the parties with
respect to the matters set forth herein. There have been no additional
oral or written representations or agreements. In case of any
inconsistency between the provisions of the Lease and this Amendment, the
latter provisions shall govern and control. This Amendment may be further
modified only in writing signed by both parties.
<PAGE>
     13.     Interpretation; Defined and Undefined Terms. This Amendment
has been prepared from a generic form intended for use with a variety of
underlying lease forms containing a variety of defined and undefined
terms. This Amendment shall be interpreted in a reasonable manner in
conjunction with the Lease. If an Exhibit is attached to this Amendment,
the term "Lease" therein shall refer to this Amendment or the Lease as
amended, and terms such as "Commencement Date" and "Lease Term" shall refer
to analogous terms in this Amendment, all as the context expressly provides
or reasonably implies. Unless expressly provided to the contrary herein:
(a) any terms defined herein shall have the meanings ascribed herein when
used as capitalized terms in other provisions hereof, (b) capitalized terms
not otherwise defined herein shall have the meanings, if any, ascribed
thereto in the Lease, and (c) non-capitalized undefined terms herein
shall be interpreted broadly and reasonably to refer to terms contained
in the Lease which have a similar meaning, and as such terms may be
further defined therein.

     IN WITNESS WHEREOF, the parties have executed this Amendment as of
the date first set forth above.
