duly qualified to do business and is in good standing as a foreign corporation
in each jurisdiction in which the nature of the business conducted or property
owned by it makes such qualification necessary, except where the failure to be
so qualified or in good standing, as the case may be, would not reasonably be
expected to, individually or in the aggregate, (x) adversely affect the
legality, validity or enforceability of the Securities or any of this Agreement,

right of any holder of the Company's securities to adjust the exercise,

Market.  The Company further agrees, if the Company applies to have the Common

respects with its reporting and filing obligations under the Exchange Act, and
will not take any action or file any document (whether or not permitted by
Exchange Act or the rules thereunder) to terminate or suspend such registration
or to terminate or suspend its reporting and filing obligations thereunder.  As
long as the Investor own Securities, if the Company is not required to file
reports pursuant to such sections, it will prepare and furnish to the Investor
and make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act such information as is required for the Investor to sell the
Securities under Rule 144 promulgated under the Securities Act.  The Company
further covenants that it will take such further

                                      -16-
<PAGE>

action as any holder of Securities may reasonably request, all to the extent
required from time to time to enable such Person to sell such Securities without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 promulgated under the Securities Act, including causing its
attorneys to render and deliver any legal opinion required in order to permit
such Person to sell its Securities under Rule 144 upon notice of an intention to
sell on Form 144 or other form of notice having a similar effect. Upon the
request of any such Person, the Company shall deliver to such Person a written
certification of a duly authorized officer as to whether it has complied with
such requirements.

     Section V.3    Legends. The certificates evidencing the Common Stock to be
                    -------
sold or otherwise issued to the Investor hereunder (including the Warrant Shares

shall be issued  free of restrictive legends of any kind and no instructions or
"stop transfer orders," so called, "stock transfer restrictions," or other
restrictions have been or shall be given to the Company's transfer agent with
respect thereto.  Prior to the first Closing, the Company will issue to the
transfer agent for its Common Stock (and to any substitute or replacement
transfer agent for its Common Stock upon the Company's appointment of any such
substitute or replacement transfer agent) instructions to deliver the Put Shares
and Warrant Shares without restrictive legends as required by this Section and
shall cause its counsel to deliver to such transfer agent any legal opinion
required in order for the transfer agent to deliver shares in such manner.
Unless such instructions cover Securities issuable at future Closings, the
Company must deliver new such instructions prior to each Closing.

                    -----------------------------------------------------------
of Right to Make a Put. The Company will immediately notify the Investor upon
----------------------
the occurrence of any of the following events in respect of a Registration
Statement or related prospectus in respect of an offering of Registrable
Securities: (i) receipt of any request for additional information from the SEC
or any other federal or state governmental authority during the period of
effectiveness of the Registration Statement the response to which would require
any amendments or supplements to the registration statement or related
prospectus; (ii) the issuance by the SEC or any other federal or state
governmental authority of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose;
(iii) receipt of any notification with respect to (A) the suspension of the
qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction or (B) the initiation or threatening of
any proceeding for such purpose; (iv) the Company becomes aware of any event
that makes any statement made in the Registration Statement or related
prospectus or any document incorporated by reference untrue in any material
respect or that requires the making of any changes in the Registration
Statement, related prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the related prospectus, it will not contain any untrue statement of a material
fact or omit to state any 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; and (v) the Company's reasonable
determination that a post-effective supplement to the prospectus or a post-
effective amendment to the Registration Statement, as the case may be, would be
appropriate; and the Company will

                                      -17-

the commencement of each calendar quarter following the Effective Date, the
Company must notify the Investor, in writing, as to its reasonable expectations
as to the dollar amount it intends to raise during such calendar quarter, if
any, through the issuance of Put Notices. Such notification shall constitute
only the Company's good faith estimate and shall in no way obligate the Company
to raise such amount, or any amount, or otherwise limit its ability to deliver
Put Notices. The failure by the Company to comply with this provision can be
cured by the Company's notifying the Investor, in writing, at any time as to its
reasonable expectations with respect to the current calendar quarter.

     Section V.6    Consolidation; Merger.  During the Commitment Period and for
                    ---------------------
period of 30 days following the last Closing, the Company shall not effect any
merger or consolidation of the Company with or into, or a transfer of all or
substantially all of the assets of the Company to, another entity  unless the
resulting successor or acquiring entity assumes by written instrument or by
operation of law the obligation to deliver to the Investor such Securities as
the Investor is entitled to receive pursuant to this Agreement.

     Section V.7    Integration.  The Company shall not, and shall use its best
                    -----------
efforts to ensure that, no affiliate of the Company shall, sell, offer for sale
or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities hereunder to the
Investor.

Company and the Investor shall consult with each other in issuing any other
press releases or otherwise making public statements or filings and other
communications  with the Commission or any regulatory agency or stock market or
trading facility with respect to the transactions contemplated hereby and
neither party shall issue any such press release or otherwise make any such
public statement, filings or other communications without the prior written
consent of the other, except that if such disclosure is required by law or stock
market regulation, in which such case the disclosing party shall promptly
provide the other party with prior notice of such public statement, filing or
other communication. Notwithstanding the foregoing, other than in the Underlying
Shares Registration Statement, the Company shall not publicly disclose the names
of the Investor, or include the names of the Investor in any filing with the
Commission, or any regulatory agency, trading facility or stock market without
the prior written consent of the Purchasers, except to the extent such
disclosure (but not any disclosure as to the controlling Persons thereof) is
required by

                                      -18-
<PAGE>

law or stock market regulations, in which case the Company shall provide the
Purchasers with prior notice of such disclosure.

     Section V.9    Use of Proceeds. The Company shall use the net proceeds from
                    ---------------

payables in the ordinary course of the Company's business and prior practices),
to redeem any Company equity or Common Stock Equivalents.

     Section V.10   Reimbursement. If the Investor, other than by reason of its
                    -------------
gross negligence or willful misconduct, becomes involved in any capacity in any
action, proceeding or investigation brought by or against any Person, including
stockholders of the Company, as a result of the consummation of the transactions
contemplated by the Transaction Documents, the Company will reimburse the
Investor for its reasonable legal and other expenses (including the cost of any
investigation and preparation and travel in connection therewith) incurred in
connection therewith, as such expenses are incurred.  The reimbursement
obligations of the Company under this paragraph shall be in addition to any
liability which the Company may otherwise have, shall extend upon the same terms
and conditions to any affiliates of the Investor actually named in such action,
proceeding or investigation, and partners, directors, agents, employees and
controlling persons (if any), as the case may be, of the Investor and any such
affiliate, and shall be binding upon and inure to the benefit of any successors,
assigns, heirs and personal representatives of the Company, the Investor and any
such affiliate and any such Person.  The Company also agrees that neither the
Investor nor any such affiliates, partners, directors, agents, employees or
controlling persons shall have any liability to the Company or any Person
asserting claims on behalf of or in right of the Company in connection with or
as a result of the consummation of the Transaction Documents except to the
extent that any losses, claims, damages, liabilities or expenses incurred by the
Company result from the gross negligence or willful misconduct of the applicable
Investor, Person or entity in connection with the transactions contemplated by
this Agreement.

circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, (whether or not requested of the

mean that such Persons other than the Investor may not obtain non-public
information in the course of conducting due diligence in accordance with the

execute and deliver, in lieu thereof, a new certificate.

     Section VIII.5  Execution.  This Agreement may be executed in two or more
                     ---------
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart.  In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

     Section VIII.6  Entire Agreement.  The Transaction Documents, together with
                     ----------------
the Exhibits and Schedules thereto contain the entire understanding of the
parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral or written, with respect to

                                      -24-
<PAGE>

such matters, which the parties acknowledge have been merged into such
documents, exhibits and schedules.

     Section VIII.7  Amendments; Waivers.  No provision of this Agreement may be
                     -------------------
waived or amended except in a written instrument signed, in the case of an
amendment, by the Company and the Investor (and, with respect to the provisions
of Section 2.3(c), Robinson Silverman) or, in the case of a waiver, by the party
against whom enforcement of any such waiver is sought.  No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of
either party to exercise any right hereunder in any manner impair the exercise
of any such right accruing to it thereafter.

     Section VIII.8  Survival.  The representations, warranties and agreements
                     --------
contained herein shall survive each Closing and the delivery and exercise of all
Securities issuable hereunder.

     Section VIII.9  Successors and Assigns.  This Agreement shall be binding
                     ----------------------
upon and inure to the benefit of the parties and their successors and permitted
assigns.  Neither the Investor nor the Company may assign this Agreement or any
rights or obligations hereunder without the prior written consent of the Company
or the Investor, as the case may be except that Investor may assign its
obligations hereunder to an Affiliate.

     Section VIII.10     Remedies. In addition to being entitled to exercise all
                         --------
rights provided herein or granted by law, including recovery of damages, the
Investor will be entitled to specific performance of the obligations of the
Company under the Transaction Documents. The Company and the Investor agree that
monetary damages may not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agree to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

     Section VIII.11     Severability. In case any one or more of the provisions
                         ------------
of this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement such substitute provision to have the same force and
effect as if it were part of this Agreement as of the date hereof.

     Section VIII.12     Headings. The headings herein are for convenience only,
                         --------
do not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.

     Section VIII.13     Fees and Expenses.  The Company shall reimburse the
                         -----------------
Investor for its legal fees and expenses incurred in connection with the
preparation and negotiation of the Transaction Documents and the preparation and
review of Closing items by paying to Robinson Silverman $30,000 concurrently
with the execution and delivery by the Investor of this Agreement

                                      -25-
<PAGE>

and $2,000 at each Closing for which it shall act as escrow agent pursuant to
the terms hereof. The amounts contemplated by the immediately preceding sentence
shall be retained by the Investor and shall not be delivered to the Company at a
Closing. Other than the amount contemplated in the immediately preceding
sentence, and except as otherwise set forth in the Registration Rights
Agreement, each party shall pay the fees and expenses of its advisers, counsel,
accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and
performance of this Agreement. The Company shall pay all stamp and other taxes
and duties levied in connection with the issuance of the Securities issuable
hereunder.

     Section VIII.14     No Third-Party Beneficiaries. This Agreement is
                         ----------------------------
intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision
hereof be enforced by, any other Persons other than with respect to the
indemnity and conflict provisions of Section 2.3, which are intended for the
benefit of and may be enforced by Robinson Silverman or such other escrow agent
as may after the date of this Agreement be appointed by the parties hereto.
