outstanding (as calculated under Rule 13d-1(e)). On February 8, 1993 Marcus
Schloss (and Douglas Schloss and Richard P. Schloss, as controlling persons)
filed a statement on Schedule 13G in respect of Marcus Schloss's ownership of
such 599,700 Shares.
On January 4, 1994 MSCP was organized and Marcus Schloss purchased a
limited partnership interest therein for $100. On January 10, 1994 Marcus
Schloss increased its investment in MSCP by contributing to MSCP 400,000 Shares
and certain other securities (the "Contribution"). The Contribution was intended
to create for MSCP an initial investment portfolio substantially similar to
Marcus Schloss's own portfolio (excluding stocks in which Marcus Schloss was
then a registered stock exchange specialist). MSCP has effected transactions in
Shares at various times following the Contribution.
Marcus Schloss and MSCP (and Douglas Schloss, Richard P. Schloss and
Rexford, as controlling persons) filed a statement on Schedule 13D promptly
after the Contribution was made. This filing was made to address the possibility
that, following the Contribution, Marcus Schloss, MSCP, Rexford, Douglas Schloss
and Richard P. Schloss could jointly be deemed to constitute a "person" under
Section 13(d)(3) of the Securities Exchange Act of 1934. Any such "person" would
not qualify to file Schedule 13G under Rule 13d-1(b)(1) because certain of its
constituent parties were not persons of a type described in Rule 13d-1(b)(1)(ii)
(A)-(G).
On August 25, 1997 Cambrex Corp. announced that it had signed an
agreement to purchase the Company for $130.9 million, or $11.625 per Share. Each
of the reporting persons on this Schedule 13D may have taken (and may take) that
information and other factors into account in purchasing or selling Shares on or
Page 15 of 25
<PAGE>
after August 25, 1997. Otherwise, no such reporting person has or has had any
intention, plan or proposal with respect to paragraphs (a) through (j) of Item
4.
Item 5. Interest in Securities of the Issuer.
(a) As of the close of business on August 25, 1997, Marcus Schloss
beneficially owned 226,200 Shares, representing approximately 2.1% of the
10,760,866 Shares outstanding, as most recently reported by the Company on its
Quarterly Report on Form 10-Q for the fiscal quarter ended April 30, 1997. As of
the close of business on August 25, 1997, MSCP beneficially owned 588,600
Shares, representing approximately 5.5% of the Shares outstanding. As of the
close of business on August 25, 1997, Rexford Offshore beneficially owned
142,900 Shares, representing approximately 1.3% of the Shares outstanding. As of
the close of business on August 25, 1997, Rexford Fund beneficially owned 50,000
Shares, representing approximately 0.5% of the Shares outstanding. Each of
Douglas Schloss and Richard P. Schloss may be deemed to control Marcus Schloss,
Rexford, Rexford Offshore and Rexford Fund and, through Rexford, each of them
may be deemed to control MSCP. Marcus Schloss, Rexford, MSCP, Rexford Offshore
and Rexford Fund therefore may be deemed to be under common control. In
addition, each of Douglas Schloss and Richard P. Schloss may be deemed through
Rexford Offshore to have discretionary power over the investments of MOFL.
Accordingly, (i) each of Douglas Schloss and Richard P. Schloss may be
considered to have beneficial ownership of the entire 1,007,700 Shares owned of
record by Marcus Schloss, MSCP, MOFL and Rexford Fund (representing
approximately 9.4% of the outstanding Shares), (ii) Rexford may be considered to
have beneficial ownership of the 588,600 Shares owned of record by MSCP, and
(iii) Rexford Offshore may be considered to have beneficial ownership of the
142,900 Shares owned of record by MOFL. As of the close of business on August
25, 1997, Mark K. Schmidt beneficially owned 3,350 Shares, representing less
than 0.1% of the Shares outstanding. The 3,350 Shares beneficially owned by Mr.
Schmidt include 1,850 Shares owned by Mr. Schmidt and an additional 1,500 Shares
owned by his spouse in an account over which Mr. Schmidt holds a power of
attorney.
Alison Schloss, the spouse of Douglas Schloss, owns of record 900
Shares and is the trustee of two trusts which, in the aggregate, own of record
2,600 Shares. The beneficiaries of such trusts are the children of Alison
Schloss and Douglas Schloss. Douglas Schloss disclaims beneficial ownership of
all such Shares owned by Alison Schloss or such trusts.
(b) Marcus Schloss has sole power to vote and sole power to dispose of
all 226,200 Shares owned of record by it. MSCP has sole power to vote and sole
power to dispose of all 588,600 Shares owned of record by it. Rexford Fund has
sole power to vote and sole power to dispose of all 50,000 Shares owned of
record by it. Douglas Schloss and Richard P. Schloss, each of whom may be deemed
to control each of Marcus Schloss and Rexford Fund, direct the investments and
voting of Marcus Schloss and Rexford Fund. Rexford, as the sole general partner
of MSCP, directs the investments and voting of MSCP. As stated above, each of
Douglas Schloss and Richard P. Schloss may be deemed to control Rexford and
thereby MSCP.
Page 16 of 25
<PAGE>
Pursuant to the Investment Management Agreement, Rexford Offshore has
discretionary power to vote and to dispose of any securities owned of record by
MOFL. Rexford Offshore therefore may be deemed to have sole power to vote and
sole power to dispose of the 142,900 Shares owned of record by MOFL. As stated
above, each of Douglas Schloss and Richard P. Schloss may be deemed to control
Rexford Offshore.
Mark K. Schmidt has sole power to vote and sole power to dispose of the
3,350 Shares he beneficially owns.
(c) Schedule I hereto sets forth all transactions in the Shares during
the past 60 days by MSCP and MOFL. There have been no transactions in the Shares
during the past 60 days by any of Marcus Schloss, Rexford, Rexford Offshore,
Rexford Fund, Douglas Schloss, Richard P. Schloss or Mark K. Schmidt.
(d) None.
(e) Not applicable.
Item 6. Contracts, Arrangements, Understandings or
Relationships with Respect to Securities of the
Issuer.
Each of MSCP and MOFL is offering its securities on an ongoing basis to
selected investors. The separate private placement memoranda (the "Memoranda")
relating to the limited partnership interests of MSCP or to the shares of MOFL,
as the case may be, disclose that potential conflicts of interest could exist
between Marcus Schloss and MSCP, or between Marcus Schloss and MOFL, because (i)
Marcus Schloss invests in securities for its own account, (ii) Marcus Schloss,
MSCP and MOFL will invest in many of the same securities, and (iii) Marcus
Schloss and MSCP, or Marcus Schloss and Rexford Offshore, as the case may be,
could be deemed to be under common control. Accordingly, Marcus Schloss, MSCP
and MOFL have adopted certain procedures they follow in their proprietary
trading activities (excluding market making transactions by Marcus Schloss in
securities for which it is a registered NASDAQ market maker). These procedures
apply to transactions in the Shares. In relevant part, the procedures provide
that:
A. MSCP and MOFL will always have priority over Marcus Schloss in
regard to contemporaneous purchases or sales of any specific class of
securities. Accordingly, if at any time Marcus Schloss and MSCP or MOFL
intend to purchase a specific class of securities, and only a limited
amount of those securities is then available for purchase at a suitable
price, MSCP and MOFL shall have the right to purchase, on a pari passu
basis, all of the available securities (or as many as they choose to
purchase) before Marcus Schloss purchases any. If at any time Marcus
Schloss and MSCP or MOFL intend to sell a specific class of securities, and
not all of the securities they intend to sell can then be sold at a
suitable price, MSCP and MOFL shall have the right to sell, on a pari passu
basis, all of the securities they intend
Page 17 of 25
<PAGE>
to sell (subject to the availability of willing purchasers) before
Marcus Schloss sells any such securities.
B. Whenever Marcus Schloss and MSCP or MOFL simultaneously
purchase the same securities, or simultaneously sell the same securities,
MSCP and MOFL shall receive the same price as Marcus Schloss or a better
price. Whenever MSCP and MOFL simultaneously purchase the same securities,
or simultaneously sell the same securities, they shall receive the same
price. All same-day purchases or sales shall be deemed "simultaneous" for
purposes of this procedure.
C. Subject to certain limited exceptions, Marcus Schloss, MSCP and
MOFL will not sell any securities to one another.
Marcus Schloss, MSCP and MOFL have not made any undertakings in the
Memoranda regarding the voting of securities. Marcus Schloss, MSCP, Rexford
Offshore and Rexford Fund believe, however, that they ordinarily will vote in
the same manner any securities (including the Shares) that they or MOFL may own.
The foregoing arrangements among Marcus Schloss, MSCP and MOFL are
described in the Memoranda but are not the subject of any written contract or
agreement. Also, as the general partner and a limited partner, respectively, of
MSCP, Rexford and Marcus Schloss participate in any investments (including the
Shares) made by MSCP to the extent of their respective partnership interests.
Under the Investment Management Agreement, Rexford Offshore manages the
investment of MOFL's assets and has discretionary power to vote and to dispose
of any securities MOFL may acquire. MOFL is an exempted company organized under
the laws of the Cayman Islands. Its principal business is investing in
securities. The business address for MOFL is c/o Goldman Sachs (Cayman) Trust,
Limited, P.O. Box 896GT, Harbour Center, Second Floor, George Town, Grand
Cayman, Cayman Islands, B.W.I. In performing its duties as investment manager
for MOFL, Rexford Offshore is subject to the policies and ultimate control of
MOFL's board of directors.
Rexford Offshore is entitled under the Investment Management Agreement
to receive periodic management fees from MOFL and may also earn annual incentive
fees. Rexford Offshore therefore has an indirect interest in the performance of
any investments (including the Shares) made by MOFL. The Investment Management
Agreement will remain in effect through December 31, 1997, and from year to year
thereafter, except that it may be terminated by Rexford Offshore or MOFL upon 90
days' written notice.
Mark K. Schmidt is an officer of Marcus Schloss. Mr. Schmidt may
participate in the review and evaluation of investments made by Marcus Schloss,
MSCP and MOFL but does not have sole or shared power to vote (or to direct the
voting of) or to dispose of (or to direct the disposition of) any securities
owned by Marcus Schloss, MSCP or MOFL.
Page 18 of 25
<PAGE>
Except as stated above, there are no contracts, arrangements, under
standings or relationships (legal or otherwise) among Marcus Schloss, Rexford,
MSCP, Rexford Offshore, Rexford Fund, Douglas Schloss, Richard P. Schloss or
Mark K. Schmidt, and any executive officer, director or controlling person of
Marcus Schloss, Rexford, MSCP, Rexford Offshore or Rexford Fund, or between any
such person and any other person, with respect to any securities of the Company.
