The Investor further sets forth statements upon which you may rely to determine
the suitability of the Investor to purchase the Shares.

         2. REPRESENTATIONS AND UNDERSTANDINGS. The Investor hereby makes the
following representations, warranties and agreements and confirms the following
understandings with the Company:

            (i)    The Investor has reviewed the Company's SEC filings
(including but not limited to, its Annual Reports on Form 10-K (as amended on
Form 10-K/A) for the fiscal years ended December 31, 1998 and December 31, 1999,

June 16, 2000 describing the Company's contemplated merger with Cereus
Technology Partners, Inc., (the "MERGER")), and has received a copy of a draft
Form S-4, with respect to the Merger (the "DRAFT S-4"), (collectively, the
"Company SEC Filings") and has had an opportunity to question representatives of
the Company and obtain such additional information concerning the Company as the
Investor has requested.

            (ii)   The Investor has sufficient experience in financial and
business matters to be capable of utilizing such information to evaluate the
merits and risks of the Investor's investment, and to make an informed decision
relating thereto; or the Investor has utilized the services of a purchaser
representative and together they have sufficient experience in financial and
business matters that they are capable of utilizing such information to evaluate
the merits and risks of the Investor's investment, and to make an informed
decision relating thereto.

            (iii)  The Investor has evaluated the risks of this investment in
the Company, including those risks particularly described in the Draft S-4, and
has determined that the investment is

                                       1
<PAGE>   2

suitable. The Investor has adequate financial resources for an investment of
this character, and at this time it could bear a complete loss of its
investment. The Investor understands that any projections which may be made in
the Draft S-4 are mere estimates and may not reflect the actual results of the
Company's operations.

            (iv)   The Investor understands that the Shares are not being
registered under the Securities Act of 1933, as amended (the "1933 ACT"), on the
ground that the issuance thereof is exempt under Section 4(2) of the 1933 Act
and Rule 506 of Regulation D promulgated thereunder, and that reliance on such
exemption is predicated in part on the truth and accuracy of the Investor's
representations and warranties. The Investor covenants not to sell, transfer or
otherwise dispose of any of the Shares unless such Shares have been registered
under the 1933 Act, or an exemption from registration is available.

            (v)    The Investor understands that the Shares are not being
registered under the securities laws of certain states on the basis that the
issuance thereof is exempt as an offer and sale not involving a public offering
in such state. The Investor understands that reliance on such exemptions is
predicated in part on the truth and accuracy of the Investor's representations
and warranties. The Investor covenants not to sell, transfer or otherwise
dispose of any of the Shares unless such Shares have been registered under the
applicable state securities laws, or an exemption from registration is
available.

            (vi)   The Investor is an Accredited Investor as defined in Rule 501
of Regulation D promulgated under Section 4(2) of the 1933 Act.

            (vii)  The Investor has no need for any liquidity in its investment
and is able to bear the economic risk of his investment for an indefinite period
of time. The Investor has been advised and is aware that: (a) there is a limited
public market for the Shares; (b) it may not be possible to liquidate the
investment readily; (c) the Investor must bear the economic risk of its
investment in the Shares for an indefinite period of time because the Shares
have not been registered under the 1933 Act and applicable state law; (d) a
legend as to the restrictions on transferability of the Shares will be made on
the Shares, and (e) a notation in the appropriate records of the Company will be
made with respect to any restrictions on transfer of the Shares.

            (viii) The Investor has relied solely upon the Company's SEC
filings, the Draft S-4, the Company's representations and warranties herein and
independent investigations made by him or his purchaser representative with
respect to the Shares subscribed for herein, and no oral or written
representations other than as referred to herein have been made to the Investor
or relied upon by the Investor.

            (ix)   The Investor agrees not to transfer or assign this
subscription or any interest therein.

            (x)    The Investor hereby acknowledges and agrees that, except as
may be specifically provided herein, the Investor is not entitled to withdraw,
terminate or revoke this subscription once it has been duly executed by both
parties listed on the signature page hereto.

            (xi)   If the Investor is a partnership, corporation or trust, it
has been duly formed, is validly existing, has full power and authority to make
this investment, and has not been formed for the specific purpose of investing
in the Shares. This Subscription Agreement and all other documents executed in
connection with this subscription for Shares are valid, binding and enforceable
agreements of the Investor.

         3. INDEMNIFICATION. The representations, warranties and agreements of
the parties contained herein are continuing in nature and shall survive the
acceptance of this Subscription Agreement. Each party hereby agrees to indemnify
and hold harmless the other party and all of its affiliates, attorneys,
accountants, employees, officers, directors, members and agents from any
liability, claims, costs, damages, losses or expenses incurred or sustained by

         declarations, filings, registrations, notices, authorizations, consents

1997 (the documents referred to in clauses (a), (b) and (c) are collectively
referred to as the "COMPANY SEC REPORTS"). As of their respective dates, the
Company SEC Reports contained no untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The audited financial statements for the fiscal year ended
December 1999 and the two prior fiscal years, and the unaudited consolidated
financial statements of Company included in Company's Quarterly Report on Form
10-Q for the period ended March 31, 2000 (collectively, the "COMPANY FINANCIAL
STATEMENTS"), have been prepared in accordance with GAAP (except as may be
indicated therein or in the notes thereto) and fairly present the financial
position of Company and its Subsidiaries as of the dates thereof and the results
of their operations and changes in financial position for the periods then
ended. Since March 31, 2000, there has not occurred any event, circumstance or
state of facts that would reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect on the Company.

            (vi)  Litigation. There is no suit, claim, action, proceeding or
investigation pending or, to the knowledge of Company, threatened against
Company or any Subsidiary of Company before any governmental entity that would
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect, and, to the knowledge of Company, there are no existing
facts or circumstances that would reasonably be expected to result in such a
suit, claim, action, proceeding or investigation. Company is not aware of any
facts or circumstances which would reasonably be expected to result in the
denial of insurance coverage under policies issued to the Company and its
Subsidiaries in respect of such suits, claims, actions, proceedings and
investigations for which Company has a reasonable expectation of obtaining
insurance coverage, except in any case as would not reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect.

            (vii) Intellectual Property. Except as would not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect, (i) Company and its Subsidiaries own or possess adequate licenses or
other valid rights to use all patents, patent applications, patent rights,

copyrights and copyright registrations and applications, copyright rights,
service marks, trade secrets, applications for trademarks and for service marks,
know- how and other proprietary rights and information used or held for use in

currently conducted (collectively, the "COMPANY IP"), free and clear of all
liens other than those in favor of PNC Bank, National Association ("PNC"), and
(ii) Company is unaware of any assertion or claim challenging the ownership, use
or validity of any of the foregoing. The licenses associated with the Company IP
are valid and binding obligations of Company, enforceable in accordance with
their terms, and there are no material breaches or defaults thereunder. The
conduct of the respective businesses of Company and its Subsidiaries as
currently conducted does not infringe upon any patent, patent right, license,
trademark, trademark right, trade dress, trade name, trade name right, service
mark, copyright or copyright right of any third party that would reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect. To the knowledge of Company, there are no infringements of any
proprietary rights owned by or licensed by or to the Company or any Subsidiary
of the Company that could reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.
