duly qualified and licensed to do business, and is in good standing (and has

The Company has no outstanding bonds, debentures, notes or other obligations or
securities entitling the holders thereof to vote (or which are convertible or
exercisable for securities having the right to vote) with the stockholders of
the Company on any matter. A complete and correct list of each outstanding
Option and Settlement Warrants, the holders and the exercise price thereof is
set forth on Schedule 2.3, and, as to each such Option, whether the same is
vested. Since December 31, 1999, the Company (i) has not issued any shares of

the shares of Common Stock. To the extent that any options, warrants or any of
the other rights described above are outstanding, neither the issuance and sale
of the Preferred Stock and the Warrants, nor any issuance of Common Shares on

conversion price or number of shares issuable upon the exercise or conversion of
any such options, warrants or other rights.

the transactions contemplated hereby and thereby (a) are within its power and
authority and (b) have been duly authorized by all necessary action on the part

respective terms, except as enforceability against each Purchaser may be limited

legal and equitable limitations on the enforceability of specific remedies
(regardless of whether enforcement is considered in a proceeding in equity or at
law).

               -----------------------
performance by each Purchaser of this Agreement and the other Transaction
Documents nor the consummation of the transactions contemplated hereby or
thereby will (a) conflict with, or result in a breach or a violation of, any

modification, cancellation, prepayment, suspension, limitation, revocation or
acceleration, under (i) any Law, or (ii) any Commitment of such entity, or to
which such entity or any of its assets or properties is subject, except, with
respect to the matters set forth in clause (ii), for breaches, violations,
defaults, Encumbrances, or rights of termination, modification, cancellation,
prepayment, suspension, limitation, revocation or acceleration, which,
individually or in the aggregate, could not have a Material Adverse Effect on
the ability of such entity to consummate the transactions contemplated hereby;
or (c) require any consent, approval or authorization of, notification to,
filing with, or exemption or waiver by, any Governmental Entity or any other
Person on the part of such entity.

the Company's Common Stock.

earlier of the termination of this Agreement or the Closing, other than in
connection with the transactions contemplated hereby, neither the Company nor

of providing information regarding the Company or any of the Subsidiaries or
their respective businesses to any Person), directly or indirectly, any
inquiries, discussions, offers or proposals for, continue or enter into

identity of any Person making any M&A Transaction and the nature and terms of
any such M&A Transaction and to keep the Purchasers promptly and fully informed
as to the status thereof whether made before or after the date of this
Agreement.

               --------------------------------------
the Company shall deliver to the Purchasers complete and correct copies of all
press releases and public filings relating to the Transaction Documents, the
transactions contemplated thereby and Company corporate matters made between the

prior to release in the form in which it will be issued.

          4.4. Consents; Approvals. The Company shall use its reasonable best
               -------------------
efforts, not requiring the expenditure of a material sum or the making of some

                                                    --------
without limitation (i) Consents required to avoid any breach, violation,

acceleration set forth on Schedule 2.9 or required to be set forth thereon, (ii)
all Consents pursuant to the Company's or any Subsidiary's financing documents,
including, without limitation, all indentures and credit agreements of the
Company or any Subsidiary, and (iii) all United States and foreign governmental
and regulatory rulings and approvals), and the Company shall make all filings
(including, without limitation, all filings with United States and foreign
governmental or regulatory agencies), required or desirable in connection with
the authorization, execution and delivery of this Agreement and the other
Transaction Documents and the consummation of the transactions contemplated
hereby and thereby; provided, however, no payment (other than filing fees
related to the matters contemplated hereby) or other accommodation shall be made
by the Company in connection with obtaining any of the foregoing without the
Purchasers' prior written consent. The Purchasers shall cooperate with the
Company in obtaining such Consents. The Company also shall use its reasonable
best efforts, not requiring the expenditure of a material sum or the making of
some other material accommodation, to obtain all necessary state securities laws
or blue sky permits and approvals required to carry out the transactions
contemplated hereby and shall furnish all information as may be reasonably
requested in connection with any such action.

          4.5. Listing. The Company shall use its best efforts to continue to
               -------
have its Common Stock quoted on the NASDAQ national market system or other
comparable national exchange prior to the Closing, and for so long as any shares
of Preferred Stock, Warrants or any Common Shares issued upon conversion or
exercise of the Preferred Stock and Warrants are outstanding. Prior to the
Closing, the Company shall prepare and submit to the NASDAQ a listing
application covering the shares of Common Stock issuable upon conversion of the
Preferred Stock and exercise of the Warrants and shall obtain approval for the
listing of such shares, subject to official notice of issuance.

          4.6. Board Representation; VCOC. (a) Section 4 of the Certificate of
               --------------------------
Designation provides that the holders of Preferred Stock and Warrants shall be
entitled to elect one director (the "Preferred Stock Designee") to the Board of
Directors of the Company subject to the terms set forth therein. For so long as
the Purchasers and their Affiliates, as holders of the Preferred Stock and
Warrants maintain ownership at the Ownership Threshold, shall have the right
under this Agreement and the Certificate of Designation to designate the
Preferred Stock Designee, TWCP shall have the right, separately enforceable by
it without further action required or permitted by any of the Purchasers or
their Affiliates, to designate such Preferred Stock Designee.

               (b)  In the event the Certificate of Designation is no longer in
effect, and so long as the Purchasers and their Affiliates beneficially own in
the aggregate Preferred Stock, Warrants and Common Shares issuable upon
conversion or exercise thereof representing (and assuming conversion and
exercise of all such Preferred Stock and Warrants) greater than 15% of the
Common Shares (assuming such conversion and exercise) acquired by the Purchasers
in the aggregate at the Closing (and adjusting for

                                     -26-
<PAGE>

stock splits, stock combinations and like transactions) (such ownership
threshold referred to as the "Ownership Threshold"), TWCP shall have the right
                              -------------------
to designate hereunder, at all times and from time to time, one director of the
Company (individuals designated pursuant to this paragraph, the "Purchasers'
                                                                 -----------
Designee"). In the event of a vacancy caused by the disqualification, removal,
--------
resignation or other cessation of service of any Purchasers' Designee from the
Board, the Board shall elect as a director (to serve until the term of such
Purchaser Designee would have expired) a new Purchasers' Designee who has been
designated by TWCP in an additional Purchasers' Designee Notice that has been
provided to the Company at least seven (7) days prior the date of a regular
meeting of the Board. TWCP shall nominate each Purchasers' Designee pursuant to
an additional Purchasers' Designee Notice in advance of each meeting of
shareholders at which such Purchasers' Designee is to be elected.

          (c)  TWCP shall provide notice to the Company (the "Purchasers'
                                                              -----------
Designee Notice") as required by Section 4.6(a) above for each Purchasers'
---------------
Designee, which notice shall contain the following information:  (i) the name of
the Person it has designated to become director, and (ii) all information
required by Regulation 14A and Schedule 14A under the Exchange Act with respect
to each such Purchasers' Designee.  Subject to Section 4.6(c) below, the
Purchasers' Designee may be any person designated by TWCP, including persons who
are officers, directors or employees of the Purchasers or their Affiliates.

          (d)  The Company agrees to include the Purchasers' Designee to be
added to or retained on the Board pursuant to this Agreement in the slate of
nominees recommended by the Board to the Company's shareholders for election as
director and shall use its reasonable efforts to cause the election or
reelection of a Purchasers' Designee to the Board at each meeting of
shareholders at which the Purchasers' Designee is up for election, including
soliciting proxies in favor of the election of such Persons, it being understood
that efforts consistent with those used for other members of the slate
recommended by the Board shall be deemed reasonable. In the event that,
notwithstanding the provisions of this Section 4.6(d), the Purchasers' Designee
is not elected to the Board then, at the written request of TWCP made within 30
days after the date of the shareholder meeting at which the Purchasers' Designee
was not elected, the Company shall cause, at the request of TWCP, the
appointment of the Purchaser's Designee or any other Person designated by TWCP,
as a non-voting observer (a "Non-Voting Observer") to the Board of the Company;
                             -------------------
it being understood that TWCP may from time to time change the designation of
such Non-Voting Observer. The Company shall afford to any Purchasers' Designee
who serves as a Non-Voting Observer, on as nearly equivalent basis as is
possible (other than the right to vote) as would have been the case if the
Purchasers' Designee had been elected to the Board, the opportunity to
meaningfully participate in, express views with respect to and have influence on
the deliberations of the Board, including through receipt, at the same time as
the Board receives the same, of all information and material as is distributed
to the Board.

                                     -27-
<PAGE>

               (e)  So long as the Purchasers and their Affiliates beneficially
own in the aggregate Preferred Stock, Warrants and Common Shares exceeding the
Ownership Threshold, without the prior written consent of TWCP, the Board of
Directors shall not amend the provisions of the by-laws of the Company, as
amended in accordance with Section 5.2(x) specifying that the size of the entire
Board shall consist of eight members.

               (f)  So long as the Purchasers and their Affiliates beneficially
own in the aggregate Preferred Stock, Warrants and Common Shares exceeding the
Ownership Threshold, TWCP shall have the right to consult with and advise
management of the Company on significant business issues, including finances and
accounts of the Company and management's proposed annual operating plans, and
meet with management at the Company's facilities at mutually agreeable times for
such consultation and advice, including to review progress in achieving said
plans subject to the execution of a mutually acceptable non-disclosure
agreement. The Company agrees to consider the advice given and any proposals
made by TWCP, provided the Company should be under no obligation to accept or
follow such advice.

               (g)  The rights set forth in this Section 4.6 are intended to
satisfy the requirement of contractual management rights for purposes of
qualifying TWCP's interests in the Company as venture capital investments for
purposes of the Department of Labor's "plan assets" regulations, and in the
event such rights are not satisfactory for such purpose as to TWCP, the Company
and the Purchasers shall reasonably cooperate in good faith to agree upon
mutually satisfactory management rights which satisfy such regulations.

               (h)  Unless otherwise agreed by the Company, the Purchasers shall
cause the Purchasers' Designee then serving on the Board or as a Non-Voting
Observer to resign from the Board or as a Non-Voting Observer immediately at any
time after the Purchasers and their Affiliates beneficially own in the aggregate
Preferred Stock, Warrants and Common Shares less than the Ownership Threshold.

          4.7. Committees. (a) The Preferred Stock Designee or Purchaser's
               ----------
Designee, as the case may be, shall be granted representation (as of the Closing
Date) on all Board committees, including the audit and compensation committees.
In the event that a Non-Voting Observer is serving on the Board as the
representative for the Purchasers, such Non-Voting Observer shall be afforded,
on as nearly equivalent basis as is possible (other than the right to vote) the
opportunity to meaningfully participate in and express views with respect to the
deliberations of the committees.

                                     -28-
<PAGE>

          (b)   The Board will not establish an executive committee authorized
to exercise the power of the Board generally unless the Purchasers are granted
representation on such committee proportional to its representation on the
Board, nor will the Board establish or employ committees (unless the Purchasers
are granted proportional representation thereon) as a means designed to
circumvent or having the effect of circumventing the rights of the Purchasers
under this Agreement to representation on the Board.

          4.8.  Certificate of Designation. The Company shall, prior to or
                --------------------------
concurrently with the Closing, cause the Certificate of Designation to be filed
with the Secretary of State of the State of Delaware as set forth in the form of
the Certificate of Designation attached hereto as Exhibit 2.2.

          4.9.  Cooperation. Each of the Purchasers and the Company agrees to
                -----------
use its reasonable best efforts to take, or cause to be taken, as promptly as
practicable all such further actions as shall be necessary to make effective and
consummate the transactions contemplated by this Agreement.

          4.10. Covenants to Provide Information. The Company covenants and

respect of such period, the financial statements and information delivered
