has been convicted in a criminal proceeding (excluding
traffic violations or similar misdemeanors) or has been a
party to a civil proceeding of a judicial or administrative
body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities
laws or finding any violation with respect to such laws.
(f) All individuals referred to above are United
States citizens unless otherwise indicated.
Item 3. Source and Amount of Funds or Other Consideration.
The aggregate purchase price of the Units was
$787,500; these funds were obtained from the Purchaser's
available cash.
Item 4. Purpose of Transaction.
The Purchaser purchased the Units pursuant to a
Common Stock and Warrant Purchase Agreement dated as of
July 2, 1997 (the "Purchase Agreement"), by and among the
Company, the Purchaser and other purchasers specified therein
(collectively, the "Purchasers").
The Purchaser purchased the Units from the Company as
an investment. Depending on market conditions and other
factors, the Purchaser may, at any time or from time to time,
sell all or some of its securities of the Company, or may
purchase additional securities of the Company in the open
market or in private transactions.
Pursuant to Section 9 of the Purchase Agreement, the
Company has filed a Registration Statement on Form S-3 (the
"Registration Statement") with the Securities and Exchange
Commission (the "Commission") registering the sale by the
Purchasers, from time to time, of the Common Stock purchased
in the Unit financing and of the Common Stock issuable upon
exercise of the Warrants that the Purchasers acquired in the
Unit financing.
Except as set forth above, the reporting persons have
no plans or proposals which relate to or would result in the
following types of transactions or events:
(a) an extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving the Company
or any of its subsidiaries;<PAGE>
CUSIP No. 09058W-10-1 SCHEDULE 13D Page 16 of 21
(b) a sale or transfer of a material amount of assets
of the Company or any of its subsidiaries;
(c) any change in the present board of directors or
management of the Company, including any plans or proposals
to change the number or term of directors or fill any
existing vacancies on the board;
(d) any material change in the present capitalization
or dividend policy of the Company;
(e) any other material change in the Company's
business or corporate structure;
(f) changes in the Company's charter, by-laws or
instruments corresponding thereto or other actions which may
impede the acquisition of control of the Company by any
person;
(g) causing a class of securities of the Company to
be delisted from a national securities exchange or cease to
be quoted in an inter-dealer quotation system of a registered
national securities association;
(h) a class of equity securities of the Company
becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Securities Exchange Act; or
(i) any action similar to those enumerated above.
Item 5. Interest in Securities of the Issuer
(a) The Company has informed the reporting persons
that on July 14, 1997, 17,134,888 shares of Common Stock were
outstanding. As of the date hereof, the Purchaser
beneficially owns 3,032,192 shares of Common Stock, which
represents beneficial ownership of approximately 16.5% of the
issued and outstanding shares of Common Stock (calculated in
accordance with Rule 13d-3(d)(1)(i) of the Securities
Exchange Act of 1934).
(b) Because the Purchaser's voting and investment
decisions concerning the above securities may be made by or
in conjunction with the other reporting persons, each of the
reporting persons may be deemed a member of a group that
shares voting and dispositive power over all of the above
securities. Although the reporting persons are reporting
such securities as if they were members of a group, the
filing of this Schedule 13D shall not be construed as an
admission by any reporting person that it is a beneficial<PAGE>
CUSIP No. 09058W-10-1 SCHEDULE 13D Page 17 of 21
owner of any securities other than those directly held by
such reporting person.
Under the definition of "beneficial ownership" in
Rule 13d-3 under the Securities Exchange Act of 1934, it is
possible that the directors and executive officers of H&Q
Group, H&Q California or H&Q Management Corporation might be
deemed the "beneficial owners" of some or all of the securi-
ties to which this statement relates in that they might be
deemed to share the power to direct the voting and
disposition of such securities. Neither the filing of this
statement nor any of its contents shall be deemed to
constitute an admission that any such individual is the
beneficial owner of any of the securities to which the
statement relates, either for purposes of Section 13(d) of
the Securities Exchange Act of 1934 or for any other purpose,
and such beneficial ownership is expressly disclaimed.
(c) During the past 60 days, the only transaction
effected by the reporting persons in the Issuer's securities
was the Purchaser's acquisition of 1,050,000 Units, as
described in more detail above.
(d) Not applicable.
(e) Not applicable.
Item 6. Contracts, Arrangements, Understandings or
Relationships with Respect to Securities of the
Issuer
The Purchaser acquired the Units pursuant to the
Purchase Agreement which is described in Item 4 above. The
Purchase Agreement is Exhibit 5 to this Schedule 13D and is
incorporated by reference.
