owns. With respect to Mr. Paulson's 10,565,234 privately beneficially-owned
shares of Common Stock, this is also a group filing (Paulson and LLC).

        On or about February 7, 2000, LLC's beneficial ownership decreased by
4,022,247 shares upon the expiration, pursuant to their terms, of certain
irrevocable proxies granted by third persons to LLC.

        LLC no longer is a 5% stockholder of Issuer, and LLC will no longer
report under Schedule 13D. Neither Mr. N. Diaco and Mr. J. Diaco is any longer a
5% stockholder of Issuer, and they will no longer report under Schedule 13D
either through LLC's filings or otherwise. Mr. Paulson will file a new Schedule
13D in his own name. Mr. Gilstrap will file a new Schedule 13D in his own name.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION


        LLC used $25,408 contributed by its four Members (from their personal
funds) to purchase the securities set forth in the first paragraph of Item 5(a)
of this Statement. This $25,408 figure is net of $2,849,592 (from their personal
funds) attributable to securities which were acquired by LLC and then on
September 9, 1997 distributed to the four Members.

        Allen Paulson used $1,156,500 of his personal funds to directly purchase
4,626,000 shares of outstanding Common Stock, of which he subsequently sold
3,015,000 shares for a total of $757,500. He also used $35,295 of his personal
funds to directly purchase 11,500 shares of Common Stock in 1997 and 1998.
Approximately $2,200,000 of his personal funds, which is less than the larger
amount he contributed to LLC, is attributable to the 12,088,734 shares of Common
Stock distributed by LLC to him on September 9, 1997. He subsequently sold
3,000,000 of those shares for $3,600,000 pursuant to an agreement dated June 4,
1999. He sold another 200,000 shares on July 28, 1999 for $50,000 upon the
exercise of a private stock option he had granted. Any exercises of outstanding
stock options would be from his personal funds.

        James Gilstrap used $219,000 of his personal funds to directly purchase
876,000 of the shares of outstanding Common Stock. Also, he earlier received
150,000 shares of


                                  Page 9 of 17
<PAGE>   10

Common Stock from Issuer as a fee for services in connection with LLC's February
1995 investment in Issuer. Approximately $500,000 of his personal funds, which
is less than the larger amount he contributed to LLC, is attributable to the
2,780,654 shares of Common Stock distributed by LLC to him on September 9, 1997.
In December 1997, he gifted 5,000 shares of Common Stock to his daughters and
contributed 1,015,000 shares of Common Stock to the Jim and Sue Gilstrap Family
Limited Partnership. On February 19, 1999 he gifted 600,000 shares of Common
Stock to his daughters. Any exercises of outstanding stock options would be from
his personal funds.

        Nicholas Diaco used $1,500 of his personal funds to directly purchase
6,000 of the shares of outstanding Common Stock. Also, he earlier received
150,000 shares of Common Stock from Issuer as a fee for services in connection
with LLC's February 1995 investment in Issuer. Approximately $75,000 of his
personal funds, which is less than the larger amount he contributed to LLC, is
attributable to the 405,306 shares of Common Stock distributed by LLC to him on
September 9, 1997. On June 10, 1998, he gifted 30,000 shares of Common Stock to
friends. On January 6, 1999, he gifted 20,000 shares of Common Stock to his
daughters, and on June 15, 1999, he gifted 24,000 shares of Common Stock to his
daughters. He made additional gifts of 13,000 shares of Common Stock between
October 21, 1999 and January 18, 2000. Between June 30, 1999 and January 20,
2000, he sold 342,000 shares of Common Stock on the open market for $1,690,000.
On January 13, 2000, he exercised options to buy 110,000 shares of Common Stock
for $141,450, from his personal funds. Any exercises of outstanding stock
options would be from his personal funds.

        Approximately $75,000 of Joseph Diaco's personal funds, which is less
than the larger amount he contributed to LLC, is attributable to the 405,306
shares of Common Stock distributed by LLC to him on September 9, 1997.

ITEM 4. PURPOSE OF TRANSACTION

        LLC acquired control of Issuer through election of a majority of
Issuer's Board of Directors on May 15, 1995, and it and its Members have
retained that control until now. With the expiration of the proxies in February
2000, dispositions by Members of certain shares, and the dilution of their
shares through the issuance of Issuer Common Stock to third parties, it is not
clear that any Members retain control of Issuer. Mr. Paulson and Mr. Gilstrap
remain Directors and substantial shareholders of Issuer. Clearly LLC no longer
controls Issuer. The individual Reporting Persons' acquisitions of securities
have been for investment purposes. The September 9, 1997 distribution of Issuer
shares by LLC to its Members may be deemed to have placed control of Issuer in
Allen Paulson (although, as noted, he may no longer actually have control). The
purpose of the distribution was to give the Members more flexibility in
utilizing and controlling the Issuer shares which they formerly indirectly owned
through LLC (e.g., Mr. Paulson's pledge of shares and subsequent sale of certain
shares; see Item 6(l) and Item 6(r)).

        (a) Regarding LLC: See Items 6(d), 6(h), and 6(i), which are
incorporated herein by reference. Regarding Allen Paulson and James Gilstrap:
See Item 5(c)(1), which is incorporated herein by reference. Regarding Nicholas
Diaco: See Item 5(c)(2), which is


                                 Page 10 of 17
<PAGE>   11

incorporated herein by reference. Issuer is likely to require further
third-party equity capitalization.

        On December 9, 1997, James Gilstrap transferred 1,015,000 shares of
Issuer Common Stock to the Jim and Sue Gilstrap Family Limited Partnership. As
Mr. Gilstrap and his wife are the sole general partners of the partnership, and
he is the managing general partner of the partnership, he retains sole voting
and dispositive power. However, the economic benefit of 95.0495% of the
partnership, in the form of limited partner interests, was donated later in
December 1997 to the Jim and Sue Gilstrap Family Foundation, which is a
supporting organization for Scripps Research Institute. Accordingly, Mr.
Gilstrap disclaims any pecuniary interest in the 964,752 shares of Issuer Common
Stock (95.0495% of the partnership's 1,015,000 shares) corresponding to the
foundation's 95.0495% limited partner interest in the partnership

        (b) None.

        (c) None.

        (d) See original Statement and previous amendments.

        (e) See Item 4(a).

        (f) None.

        (g) None.

        (h) None.

        (i) None.

        (j) None.

        The Members of LLC have no such plans or proposals, or purposes, apart
from LLC's or as stated above.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

        (a) LLC beneficially owns 2,243 shares of Common Stock. 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 Amended and Restated
Secured Convertible Promissory Note. Together, all this represents 0.2% of the
Common Stock under the Rule 13d-3(d)(1) calculation (with 41,428,277 shares
outstanding at December 31, 1999). Various proxies giving LLC the right to vote
shares held by others expired on or about February 7, 2000.

        Other than through LLC, the Members have no such beneficial ownership of
Common Stock except for 10,565,234 shares beneficially owned by Mr. Paulson,


                                 Page 11 of 17
<PAGE>   12

3,255,654 shares beneficially owned by Mr. Gilstrap, 284,306 shares beneficially
owned by Mr. N. Diaco and 405,306 shares beneficially owned by Mr. J. Diaco.

        The total number of shares of Issuer Common Stock beneficially owned by
each respective Reporting Person, followed in parentheses by the percentage of
the class and the number of such shares--included in the total--which the
Reporting Person has the right to acquire, is:

<TABLE>
<S>                   <C>                <C>
LLC:                  102,243            (0.2%; 100,000)
Allen Pauson:         10,667,477         (25.7%; 54,000 plus LLC's 100,000)
James Gilstrap:       3,357,897          (8.1%; 54,000 plus LLC's 100,000)
Nicholas Diaco:       386,549            (0.9%; 42,000 plus LLC's 100,000)
Joseph Diaco:         507,549            (1.2%; LLC's 100,000)
</TABLE>


        Together, LLC and Mr. Paulson beneficially own 25.7% 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, Mr. N. Diaco and Mr. J. 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 own 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 Amendment No. 8 to
Schedule 13D, except for the following:

                (1) Pursuant to Issuer's 1995 Stock Option/Stock Issuance Plan,
each of Messrs. Paulson and Gilstrap 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 January 31, 2000,
each of Messrs. Paulson and Gilstrap has received automatic option grants for a
per-person total of 54,000 shares. Mr. N. Diaco also received such grants from
August 1995 through June 1999. Beginning in October 1997, new automatic option
grants to 10% shareholders (i.e., Mr. Paulson and, for a time, Mr. Gilstrap)
have had an exercise price equal to 110% of the fair market value of the stock
as of the grant date.

                (2) In a number of transactions between June 30, 1999 and
January 20, 2000, Mr. N. Diaco sold 342,000 shares of Common Stock on the open
market and gifted 13,000 shares of Common Stock. Also, on January 13, 2000, Mr.
N. Diaco exercised options to buy 110,000 shares of Common Stock.

                (3) On July 28, 1999, Mr. Paulson sold 200,000 shares of Common


                                 Page 12 of 17
<PAGE>   13

Stock to one of his employees upon the employee's exercise of a private stock
option which Mr. Paulson had previously granted. Also, in transactions which
have not been previously reported, Mr. Paulson purchased 11,000 shares of Common
Stock on the open market in 1997 and 500 shares of Common Stock on the open
market in 1998.

        (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.
