                        (reference dated April 4, 1996)

     re Lease between FormGen, Inc. (Lessee) and Scottsdale Airpark L.L.C. VIII
(Lessor) for the property known as 15649 N. Greenway-Hayden Loop, Scottsdale,
Arizona also known as Lot 8 North Scottsdale Airpark Unit 4, Maricopa County,
Arizona.

Anything to the contrary notwithstanding, the following in the referenced lease
are hereby modified and affirmed.

1.   Whereas the commencement date in the referenced lease is specified as
December 1, 1995 (paragraph 1.3), the actual date of possession of the subject
property by Lessee occurred on March 25, 1996. During the period from December
1, 1995 through March 24, 1996, although the Lease was in full force and effect,
Lessor acknowledges and affirms that Lessee was not in default under any
provision of the Lease and specifically was not obligated to pay rent or any
other charge during that period of time.

2.   Since possession of the subject property occurred four (4) full or
fractional months after the commencement date, therefore, during the term of the
Lease, base rent shall be increased on each May 1, beginning May 1, 1997, to an
amount which shall be three percent (3%) higher than the previous year's monthly
base rent (paragraph 1.5). Previous reference (paragraph 49) to an adjustment
occurring on January 1 is hereby voided.

3.   Since possession of the subject property occurred four (4) full or
fractional months after the commencement date, and, since the security deposit
had been deemed prepaid rent, therefore said security deposit shall be credited
to the benefit of Lessee for its monthly base rent obligation to Lessor at the
rate of $4,000.00 per month beginning October 1, 1996 and ending October 1,
1998. Reference to June 1, 1996 and June 1, 1998  in this regard is hereby
voided and replaced with October 1, 1996 and October 1, 1998, respectively
(paragraph 50).

4.   Since possession of the subject property occurred four (4) full or
fractional months after the commencement date, therefore, the expiration date is
hereby modified to become March 31, 2006. Reference to November 30, 2006 in this
regard is hereby voided and replaced with the above March 31, 2006 (paragraph
1.3).

5.   The lease is hereby reaffirmed and all other terms and conditions shall
remain the same.
