Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
Mr. Smolik and Drs. Wachter, Dees, Fisher and Scott acquired their
Common Stock from the Issuer on May 16, 1997 as a result of the merger
between Photogen, Inc. (of which they were the sole stockholders) and a
wholly-owned subsidiary of Issuer. The consideration for the Common Stock
Mr. Smolik and Drs. Wachter, Dees, Fisher and Scott received from the Issuer
was their interest in Photogen, Inc.
Dr. Weinstein and his wife acquired 3,239,350 shares of Common Stock on
December 9, 1994 from the Issuer in a private transaction (adjusted to
reflect a subsequent two-for-one reverse stock split). The purchase price
was $.0231528 per share, which Dr. Weinstein and his wife paid with their
personal funds.
-18-
<PAGE>
On May 16, 1997, the Issuer sold 2,975,359 shares of Common Stock to
Dr. and Mrs. Weinstein in a private transaction. The purchase price was
$.28568 per share, which Dr. Weinstein and his wife paid with their personal
funds. (These purchases were part of a stockholder restructuring in which
Dr. Weinstein and his wife transferred 2,714,288 shares to the Issuer's
treasury for cancellation.)
Since May of 1997, none of the reporting persons have acquired any
additional shares from the issuer. All of the reporting persons have
transferred a portion of their shares to various entities controlled by them
or disposed of certain shares to third parties by gift or sale. The
transfers of Robert J. Weinstein, M.D. and Lois Weinstein to the W.F.
Investments Enterprises Limited Partnership and the Robert and Lois Weinstein
Family Foundation, Inc. were disclosed in Amendment No. 2 to Schedule 13D
dated July 27, 1998. The transfers of Walter Fisher, Ph.D. and Timothy
Scott, Ph.D. to the Fisher Family Investment Limited Partnership and the
Scott Family Investment Limited Partnership, respectively, were also
disclosed in Amendment No. 2 to Schedule 13D.
On June 3, 1998, in a private transaction, Craig Dees, Ph.D., Walter
Fisher, Ph.D., John Smolik, Eric Wachter, Ph.D. and Timothy Scott, Ph.D.
(each, a "Seller," collectively, the "Sellers") sold 63,333 shares of common
stock each, to a third party. The buyer of the shares represented to the
Sellers that he acquired the shares for investment purposes and not with a
view to the resale or distribution thereof except in compliance with
applicable securities laws. The sale price per share was $8.21.
In November, 1998, John Smolik gifted 15,000 shares of common stock to
third parties.
In December, 1998, the reporting persons made several transfers or gifts
of stock. John T. Smolik, president of the Issuer, transferred 2,000,000
shares of common stock to the Smolik Family L.P. Mr. Smolik is the general
partner of the partnership and retains beneficial ownership of all 2,000,000
shares transferred to the partnership. Eric A. Wachter, Ph.D., transferred
200,000 shares of common stock to the Eric A. Wachter 1998 Charitable
Remainder Unitrust. Dr. Wachter is the sole trustee of the trust and
retains beneficial ownership of all 200,000 shares transferred to the trust.
Craig Dees, Ph.D., transferred 22,000 shares of common stock to the Dees
Family Foundation and gifted 3,000 shares to a third party. Dr. Dees retains
control and beneficial ownership of all 22,000 shares owned of record by the
foundation. Walter G. Fisher, Ph.D. transferred 150,000 shares to the Walt
Fisher 1998 Charitable Remainder Unitrust and gifted 4,500 shares to third
parties. Dr. Fisher is the sole trustee of the trust and retains beneficial
ownership of all 150,000 shares transferred to the trust. Timothy Scott,
Ph.D., gifted 15,000 shares to a third party.
Item 4. PURPOSE OF TRANSACTION.
Mr. Smolik and Drs. Wachter, Dees, Fisher and Weinstein are officers
and/or directors of the Issuer, and they are in a position to influence
management of the Issuer. In that capacity, they may consider from time to time
various plans for the Issuer to raise additional capital which may have the
effect of changing the present capitalization of the Issuer.
The shares of Common Stock beneficially owned by the reporting persons
are subject to an Amended and Restated Voting Agreement (the "Amended
Agreement") (which was attached as an Exhibit to Amendment No. 2 to Schedule
13D dated July 27, 1998). The Amended Agreement was entered into among Eric
Wachter, Ph.D., Craig Dees, Ph.D., Walter Fisher, Ph.D., Tim Scott, Ph.D.,
and John Smolik (the "Tennessee Stockholders") and Robert Weinstein, M.D.
(the "Chicago Stockholder"). The Amended Agreement generally provides that
the Tennessee Stockholders and Chicago Stockholder will vote shares of common
stock beneficially owned by them (i) in accordance with the unanimous
recommendation of the Board of Directors and with respect to any amendments
to the Articles of Incorporation or Bylaws, (ii) to fix the number of
directors at six, (iii) to elect to the Board of Directors four persons
nominated by holders of 80% of the shares of the Tennessee Stockholders and
one person nominated by holders of 80% of the shares of the Chicago
Stockholder (and to remove any such director at the request of the
stockholders who nominated him), and (iv) to fix the number of directors on
the Board's Executive Committee at three, two of whom will be selected by the
Tennessee Stockholders and one of whom will be selected by the Chicago
Stockholder. Accordingly, the
-19-
<PAGE>
parties to the Amended and Restated Voting Agreement may be deemed to share
voting power with respect to their shares.
Except as described above, no reporting person has any current plans or
proposals that relate to or would result in:
a. The acquisition by any person of additional securities of the Issuer,
or the disposition of securities of the Issuer;
b. An extraordinary corporate transaction, such as a merger, reorganization
or liquidation, involving the Issuer or any of its subsidiaries;
c. A sale or transfer of a material amount of assets of the Issuer or any of
its subsidiaries;
d. Any change in the present board of directors or management of the Issuer,
including any plans or proposals to change the number or term of directors
or to fill any existing vacancies on the board;
e. Any material change in the present capitalization or dividend policy of
the Issuer;
f. Any other material change in the Issuer's business or corporate structure;
g. Changes in the Issuer's charter, bylaws or instruments corresponding
thereto or other actions which may impede the acquisition of control of
the Issuer by any person;
h. Causing a class of securities of the Issuer to be delisted from a national
securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities
association;
i. A class of equity securities of the Issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Exchange
Act; or
j. Any action similar to any of those enumerated above.
