secured by all of the shares of Common Stock.

Item 4.   Purpose of Transaction.
          ---------------------- 

          Each of Raptor Ltd., Raptor L.P., TAP, Tudor BVI and Upper Mill
initially acquired the Common Stock beneficially owned by such Reporting Person
for investment purposes.  Each of such Reporting Persons intends to continue to
evaluate their respective investments in Common Stock based on the Company's
financial condition, results of operations and prospects as well as other then
existing or anticipated facts and circumstances including general economic,
market and other financial conditions.  Accordingly, each of the Reporting
Persons reserves the right to change its plans and intentions with respect to
its investment in securities of the Company at any time, as it deems
appropriate.  In particular, each of the Reporting Persons may at any time and
from time to time (i) acquire additional shares of Common Stock, (ii) dispose of
Common Stock, or (iii) enter into privately negotiated derivative transactions
with institutional counterparties to hedge the market risk of some or all of its
positions in the Common Stock.  There can be no assurance that any Reporting
Person will increase or decrease its investment in the Company or as to the
number of shares of Common Stock or derivative securities that may be bought or
sold in any such transactions.

          Except as set forth in this Schedule 13D, none of the Reporting
Persons currently has any plans or proposals which relate to or would result in
any of the transactions, actions or events enumerated in paragraphs (a) through
(j) of the instructions to Item 4 of Schedule 13D.

Item 5.   Interest in Securities of the Issuer.
          ------------------------------------ 

          Attached hereto as Schedule II is a list of the transactions by each
of the Reporting Persons in Common Stock within the past sixty days.

          Because TIC is the sole general partner of Raptor L.P. and provides
investment advisory services to Raptor Ltd., Raptor L.P., Tudor BVI and Upper
Mill, TIC may be deemed to beneficially own the shares of Common Stock owned by
each of such Reporting Persons.  TGT, as the sole general partner of TAP, may be
deemed to beneficially own the shares of Common Stock owned by TAP.  In
addition, because Mr. Jones owns a majority of the capital stock and voting
securities of TIC and indirectly owns a majority of the equity interests in TGT,
Mr. Jones may be deemed to beneficially own the shares of Common Stock deemed
beneficially owned by TIC and TGT.

          Based on the information contained in the Company's Registration
Statement on Form S-3 dated September 11, 1997 that there were 16,577,652 shares
of Common Stock issued and outstanding as of September 5, 1997, each Reporting
Person beneficially owns (or, with respect to TIC, Mr. Jones and TGT, may 

                                    Page 12
<PAGE>
 
be deemed to beneficially own) the number and percentage of outstanding shares
of Common Stock listed in the responses to Items 11 and 13, respectively, of the
cover page filed herewith for such Reporting Person. In addition, the number of
shares of Common Stock beneficially owned (or, with respect to TIC, Mr. Jones
and TGT, which may be deemed beneficially owned) by each Reporting Person with
respect to which such Reporting Person (i) has sole voting power, (ii) shares
voting power, (iii) has sole dispositive power and (iv) shares dispositive power
are listed in the responses to Items 7, 8, 9 and 10, respectively, of the cover
page filed herewith for such Reporting Person. The voting and dispositive power
is reported as shared because each of the Reporting Persons (other than TIC,
TAP, TGT and Mr. Jones) has the power to remove TIC as its investment advisor or
general partner. Each of the Reporting Persons (other than TIC, TGT and Mr.
Jones) expressly disclaim beneficial ownership of the shares of Common Stock
beneficially owned by any other Reporting Person and each of TIC, Mr. Jones and
TGT disclaim beneficial ownership of the Common Stock beneficially owned by
Raptor Ltd., Raptor L.P., TAP, Tudor BVI, Upper Mill and, in the case of TIC and
Mr. Jones, TGT.

Item 6.   Contracts, Arrangements, Understandings
          or Relationships with Respect to Securities
          of the Issuer
          ---------------------------------------------

          None.
