for a total of $757,500. His remaining shares of outstanding Common Stock are

ITEM 4.           PURPOSE OF TRANSACTION

Issuer's Board of Directors on May 15, 1995, and retains that control. The
individual Reporting Persons' acquisitions of securities have been for
investment purposes.

                  (a) See Items 6.d, 6.e, 6.i and 6.j, which are incorporated

ITEM 5.           INTEREST IN SECURITIES OF THE ISSUER

         (a) LLC beneficially owns 15,682,243 shares of Common Stock outright,
and beneficially owns (by virtue of its sole voting power) an additional
4,522,247 shares of Common Stock owned by others which LLC holds irrevocable
proxies to vote. LLC also beneficially owns, by virtue of its right to acquire
them from Issuer, 100,000 shares of Common Stock issuable upon conversion of the
Fifth Amended and Restated Secured Convertible Promissory Note. Together, all
this represents 63.5% of the Common Stock under the Rule 13d-3(d)(1) calculation
(with 31,872,628 shares outstanding today).

                  Other than through the LLC, the Members have no such 
beneficial ownership except for 1,631,000 shares beneficially owned by Mr.
Paulson, 1,046,000 shares beneficially owned by Mr. Gilstrap and 276,000 shares
beneficially owned by Mr. N. Diaco. Together, the LLC and its Members
beneficially own 72.4% of the Issuer's Common Stock.

                  Together, LLC and Mr. Paulson beneficially own 68.6% of the
Issuer's Common Stock.

         (b)      The Reporting Persons' voting and dispositive power is set
forth in the cover pages under items 7-10 on pages 2-6 of this Statement. Each
of Mr. Paulson, Mr. Gilstrap and Mr. N. Diaco has sole voting power and sole
dispositive power for his respective Issuer shares. In addition, each Member of
LLC has given Mr. Paulson a proxy to vote his respective LLC interests.  Mr.
Paulson has a sufficient interest in the LLC, even without the proxies, to
control the disposition of LLC's Issuer shares.

         (c)      No other transactions in the Common Stock were effected by
LLC, Mr. Paulson or any of the other Members since the filing of LLC's Amendment
No. 3 to Schedule 13D, except for the following:

                  (1) From April 1 through June 11, 1996, LLC exercised (in
eight separate installments) its right to make $1,800,000 of further advances
under the Third Amended and Restated Convertible Promissory Note.

                  (2) On June 12, 1996, LLC converted $1,800,000 principal
amount of the Third Amended and Restated Secured Convertible Promissory Note
into 7,200,000 unregistered shares of Common Stock. This resulted in Issuer
issuing to LLC as of June 30, 1996 the Fourth Amended and Restated Secured
Convertible Promissory Note in place of the Third Amended and Restated Secured
Convertible Promissory Note.

                  (3) On July 16, 1996, Mr. Paulson sold 15,000 shares of Common
Stock in a private transaction at $0.50 per share. On August 22, 1996, Mr.
Paulson sold a total of 3,000,000 shares of Common Stock in private transactions
at $0.25 per share.

                  (4) As of February 1, 1997, the Company and LLC amended
various terms of the Fourth Amended and Restated Secured Convertible Promissory
Note. This resulted in Issuer issuing to LLC the Fifth Amended and Restated
Secured Convertible Promissory Note in place of the Fourth Amended and Restated
Secured Convertible Promissory Note.

                  (5) Pursuant to Issuer's 1995 Stock Option/Stock Issuance
Plan, each of Messrs. Paulson, Gilstrap and N. Diaco has, on the last day of
each month beginning August 1995, been automatically granted options to purchase
1,000 shares of Issuer Common Stock, with an exercise price equal to the fair
market value of such stock as of each such date, in respect of his service as a
non-employee director. Such automatic option grants were not considered to
constitute beneficial ownership of the underlying shares until June 12, 1996,
when Issuer's shareholders voted to approve such Plan. Through March 31, 1997,
each of Messrs.
                               Page 10 of 13 Pages

<PAGE>   11

Paulson, Gilstrap and N. Diaco has received automatic option grants for a
per-person total of 20,000 shares.

         (d) No other person is known to have the right to receive or the power
to direct the receipt of dividends from, or the proceeds from the sale of, the
securities.

         (e)      Not applicable.
