ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
Article 10 of the Registrant's Certificate of Incorporation provides for
the indemnification of directors to the fullest extent permissible under
Delaware law.
Article VI of the Registrant's Bylaws provides for the indemnification of
officers, directors, employees and agents of the corporation if such person
acted in good faith and in a manner reasonably believed to be in and not opposed
to the best interest of the corporation, and, with respect to any criminal
action or proceeding the indemnified party had no reason to believe his conduct
was unlawful.
Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.
The Registrant will enter into indemnification agreements with its
directors and executive officers, and intends to enter into indemnification
agreements with any new directors and executive officers in the future.
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
Since January 1, 1993, the Registrant has issued and sold (without payment
of any selling commission to any person) the following unregistered securities
(all of which are presented without giving effect to the reverse stock split to
be effected prior to the closing of the Offering):
(1) From inception of the Company, the Registrant issued and sold
807,585 shares of Common Stock to employees, directors and consultants at
prices ranging from $.09 to $.35, upon exercise of incentive stock options
under the Registrant's 1988 Stock Option Plan, or as stock purchases in
connection with their employment with or services to the Company.
(2) From inception of the Company, the Registrant issued and sold
222,989 shares of preferred stock to employees at prices ranging from $.90
to $2.15 per share pursuant to the 1991 Employee Stock Purchase Plan in
connection with their employment with the Company.
II-1
<PAGE> 4
(3) From March 25, 1993 to January 23, 1995, Registrant issued
4,747,119 shares of Series D Preferred Stock at a price of $2.15 per share
and 124,270 warrants for the purchase of Series D Preferred Stock with an
exercise price of $2.15 per share to a total of 38 investors.
(4) In October 1994, Registrant issued to R. James Danehy, President,
Chief Executive Officer and a director of the Company a stock option
covering 800,000 shares of Common Stock at an exercise price of $0.31 per
share. 219,891 shares subject to such option which had vested were
cancelled by the Company in November 1995, and the Company allowed Mr.
Danehy to purchase 219,891 shares of Common Stock at a purchase price of
$0.31 per share through his self-directed IRA.
(5) In August 1994 the Company provided to Mr. Danehy the opportunity
to purchase $200,000 of Series D Preferred Stock at $2.15 per share and an
additional share of Common Stock at $0.84 per share for each two shares of
Series D Preferred Stock purchased. Pursuant to his right, Mr. Danehy
purchased 93,023 shares of Series D Preferred Stock and 46,512 shares of
Common Stock at $0.31 per share in January 1996.
(6) In February 1996, the Company issued approximately $12 million in
Exchange Notes in exchange for notes held by 199 holders of BioTek notes as
consideration for the acquisition of BioTek Solutions, Inc. Such Exchange
Notes were convertible into Common Stock at a conversion price of $5.00 per
share. Between February 26, 1996 and May 14, 1996 the Company issued
approximately $5.1 million of convertible subordinated debt together with
warrants to purchase 2,378,898 shares of Series D Preferred Stock at an
exercise price of $2.15 per share to 68 investors (i.e., certain current
stockholders and officers and directors of the Company).
(7) In January 1996, the Company issued 69,767 shares of Series D
Preferred Stock to Bear, Stearns & Co. Inc. as partial consideration for
services rendered in connection with the acquisition of BioTek.
The sales of the above securities were deemed to be exempt from
registration under the Securities Act in reliance on Section 4(2) of the
Securities Act, or Regulation D promulgated thereunder, or Rule 701 promulgated
under Section 3(b) of the Securities Act, as transactions by an issuer not
involving a public offering or transactions pursuant to compensatory benefit
plans and contracts relating to compensation as provided under such Rule 701.
The recipients of securities in each such transaction represented their
intention to acquire the securities for investment only and not with a view to
or for sale in connection with any distribution thereof and appropriate legends
were affixed to the share certificates and warrants issued in such transactions.
All recipients had adequate access, through their relationships with the
Company, to information about the Registrant.

ITEM 17. UNDERTAKINGS
The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
The undersigned registrant hereby undertakes that:
(1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
(2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
