Item 3. Source and Amount of Funds or Other Consideration:
The Reporting Persons EBT and CHVP each contributed
certain property, in the form of cash or securities,
to the Reporting Person BIO in exchange for a
proportionate interest in the assets of BIO. On the
basis of the agreed upon value of all contributed
securities and cash, the following Reporting Persons
are considered to have paid the following
consideration for their respective pro-rata interests
in the securities of the issuer acquired on
January 27, 1995 as assets of BIO:
EBT (for 35.6%) various securities valued at $950,048.92
CHVP (for 1%) $26,650.00 in cash
Subsequently, Reporting Person BIO converted the
Issuer's Promissory Note in the principal amount of
$220,000 for 183,334 shares on August 14, 1995.
Item 4. Purpose of Transaction: All shares reported as
being beneficially owned by any and all of the
Reporting Persons are held for investment purposes.
No Reporting Person has any present plan or proposal
or purpose to effect substantial changes in the
business, organization, form or control of the
Company.
Item 5. Interest in Securities of the Issuer: (Note:
Item 5 of the Schedule 13D originally filed by the
Reporting Persons is amended to read in its entirety
as follows):
By virtue of their status as members of BIO, each of
CHVP and EBT may be deemed the beneficial owner of
all shares held of record by BIO, over which they have
shared voting and investment power (the "BIO Shares").
By virtue of his status as the majority owner and
controlling person of CHVP, Jeffrey J. Collinson
("JJC") may also be deemed the beneficial owner of
the BIO Shares.
The number of shares reported herein by all Reporting
Persons represents a net 1,126,666 fewer shares than
were reported by the Reporting Persons on their
original Schedule 13D. The new total reflects
(i) the cashless conversion on March 29, 1995, of
Warrants covering 1,637,500 shares for a total of
327,500 shares and (ii) the purchase on August 14,
1995 of 183,334 shares issued to BIO upon the
conversion of the Issuer's promissory note in the
principal amount of $220,000. As a result, the
following Reporting Persons may be deemed to be the
beneficial owners of the following shares, with
shared or sole voting and dispositive powers as
indicated. Such shares representing 12.04% of their
class of security on the basis of 33,643,000 shares
outstanding as of 8/14/95:
BIO 2,710,834 All powers shared
EBT 2,710,834 All powers shared
CHVP 2,710,834 All powers shared
JJC 2,710,834 All powers shared
Each of the Reporting Persons disclaims beneficial
ownership of any shares except to the extent, if any,
of such Reporting Person's actual pecuniary interest
therein.
Item 6. Contracts, Arrangements, Understandings or Relationships with
Respect to Securities of the Issuer.
I. Limited Liability Company Agreement of Biotechnology Investment
Group, L.L.C.
Securities of the issuer are held by Biotechnology
Investment Group, L.L.C. ("BIO"), one of the
Reporting Persons who are signatories to this
Schedule. CHVP is the Managing Member of
<PAGE> 9 of 14
BIO. The Edward Blech Trust ("EBT") and The
Wilmington Trust Company, as voting trustee under a voting
trust dated as of January 19, 1995 ("WTC") are the other
members of BIO.
Pursuant to the Limited Liability Company Agreement
of BIO, dated as of January 19, 1995 (the "LLC
Agreement") the following terms and conditions apply
with respect to the securities of the Issuer. The
following is a summary of certain provisions
contained in the LLC Agreement, which is incorporated
herein by reference and attached hereto as Exhibit 1.
Section references are to the relevant section of the
LLC Agreement.
A. General. Pursuant to the LLC Agreement, the
management of BIO is vested in CHVP, as Managing
Member (Section 6.1), subject to restrictions on its
powers as Managing Member (Section 6.3) and on the
general powers of BIO (Section 3.3). As used in the LLC
Agreement and as pertinent to the descriptions set
forth herein, the term "Required Vote" means the
vote or written consent or approval of WTC and
EBT, unless EBT fails to give its consent,
approval or affirmative vote after due notice, in
which case the term "Required Vote" means the vote
or written consent or approval of WTC and CHVP.
(Section 1.1).
B. Voting of the Issuer's Securities. Pursuant to
the LLC Agreement, any exercise of voting rights
with respect to the Issuer's securities requires
the prior written consent of the Members acting by
Required Vote, except for votes on matters which
in CHVP's reasonable opinion, would not be adverse
to BIO (with votes on mergers, consolidations, or
sales of all or substantially all assets of the
Issuer being considered adverse to BIO), and
except for votes required on an expedited basis
such that CHVP would not have the opportunity to
solicit the approval of the Members. With respect
to each such exception, CHVP is empowered to
exercise voting rights with respect to the
Issuer's securities. (Section 3.3(ii)(l)).
C. Dispositions. Dispositions of the Issuer's
securities are governed by the LLC Agreement as
follows:
i) Securities of the Issuer may be disposed of
pursuant to a merger or consolidation of the
Issuer for cash or securities;
ii) All or any portion of the securities of the
Issuer may be disposed of, at the direction
of CHVP as Managing Member, for cash without
further consent of the members if the
Managing Member certifies to the Members that
all or substantially all cash proceeds from
such sale are to be used to pay principal,
interest or fees payable to Citibank, N.A.
(the "Bank") pursuant to a Credit Agreement
dated as of January 19, 1995 (the "Credit
Agreement") between BIO and the Bank, which
Credit Agreement is further described below;
iii) All or any portion of the securities of the
Issuer may be disposed of, at the direction
of CHVP as Managing Member, for cash at a
price that equals or exceeds minimum cash
prices established from time to time by
recommendation of CHVP and approved by WTC
and EBT; and
iv) All or any portion of the securities of the
Issuer may be disposed of, at the direction
of CHVP as Managing Member, for cash, at
prices which do not meet the minimum cash
prices described in iii) above, only with the
written consent of both WTC and EBT;
provided, however, that
(A) if WTC has consented to any such sale of
the Issuer's securities and EBT has not
so consented, CHVP, as Managing Member,
shall cause the distribution in kind to
EBT of EBT's pro rata portion of the
Issuer's
<PAGE> 10 of 14
securities proposed to be sold,
and shall sell for cash WTC's pro rata
portion of the Issuer's securities to be
sold; and
(B) if EBT has consented to such sale and
WTC has not so consented, CHVP, as
Managing Member, shall, upon the
election of EBT, distribute in kind or
sell for cash EBT's pro rata portion of
the Issuer's securities and shall take
no action with respect to WTC's pro rata
portion of the Issuer's securities
proposed to be sold. (Section 3.3(iv)).
D. Derivative Securities. Under the LLC Agreement,
BIO has no power or authority to transfer or
dispose of any put or call or other similar
arrangement with respect to the Issuer's
securities without the consent of WTC and EBT.
(Section 3.3(iv)).
E. Division of Profits and Losses. Pursuant to the
LLC Agreement, profits and losses are generally
allocated among the Members, including the
Managing Member, in accordance with their
respective percentage ownership interests.
(Sections 8.1-8.7) Distributions to the Members
generally follow the percentage interests, with provision
for special distributions to CHVP depending on the
aggregate amount of distributions made to WTC and
EBT, as set forth in the LLC Agreement.
(Sections 9.1-9.4)
II. Credit Agreement and Pledge Agreement with Citibank, N.A.
The securities of the Issuer have been pledged to the
Bank by BIO pursuant to a Pledge Agreement dated as
of January 19, 1995 (the "Pledge Agreement") in order
to secure certain obligations of BIO to the Bank
pursuant to the Credit Agreement (previously defined)
and certain promissory notes (the "Notes") delivered
pursuant to the Credit Agreement. The following is a
summary of certain provisions contained in the Credit
Agreement and the Pledge Agreement, which are
incorporated herein by reference and attached hereto
as Exhibits 2 and 3, respectively. Pursuant to the
Credit Agreement, the Bank has extended a credit
facility of up to $3,000,000 to BIO on terms and
conditions contained therein. All assets of BIO,
including all securities of the Issuer held by BIO,
have been pledged to the Bank to secure indebtedness
outstanding under the Credit Agreement. The Loan
Agreement and the Credit Agreement provide for
standard default and similar provisions which, if
triggered, would limit the power of BIO to dispose of
securities of the Issuer without the Bank's consent
and would cause a transfer of voting and investment
power if the Bank's remedies on default were
exercised under the Pledge Agreement.
