Closing Date, transferable divisible warrants (the "Warrants"), to purchase
shares of Common Stock equal to fifteen (15%) percent of the number of Shares
purchased under the relevant Put Notice. Such Warrants (substantially in the
form of Exhibit F), shall bear an exercise price per share of Common Stock equal
to 125% of the Market Price with respect to such relevant Put, and shall be
exercisable immediately upon issuance, and for a period of five (5) years
thereafter, together with cashless exercise and registration rights under the
Registration Rights Agreement.

        Section 2.5 TERMINATION OF INVESTMENT OBLIGATION. The obligation of
Investor pursuant to this Agreement to purchase shares of Common Stock shall
terminate permanently (including with respect to a Closing Date that has not yet
occurred)in the event that (a) there shall occur any stop order or suspension of
the effectiveness of any Registration Statement for an aggregate of thirty
(30)Trading Days during the Commitment Period, for any reason other than
deferrals or suspension during a Blackout Period in accordance with the
Registration Rights Agreement, as a result of corporate developments subsequent
to the Subscription Date that would require such Registration Statement to be
amended to reflect such event in order to maintain its compliance with the
disclosure requirements of the Securities Act or (b) the Company shall at any
time fail to comply with the requirements of Section 6.3, 6.4, 6.5 or 6.6 and
such failure shall continue for more than thirty (30) days.

        Section 2.6 BLACKOUT SHARES. In the event that, (a) within fifteen (15)
Trading Days following any Closing Date, the Company gives a Blackout Notice to
Investor of a Blackout Period in accordance with the Registration Rights
Agreement, and (b) the Bid Price on the Trading Day immediately preceding such
Blackout Period ("OLD BID PRICE") is greater than the Bid Price on the first
Trading Day following such Blackout

<PAGE>   14

Period that Investor may sell its Registrable Securities pursuant to an
effective Registration Statement ("NEW BID PRICE"), then the Company shall issue
to Investor the number of additional shares of Registrable Securities (the
"BLACKOUT SHARES") equal to the difference between (i) the product of the number
of Put Shares held by Investor immediately prior to the Blackout Period that
were issued on the most recent Closing Date(the "REMAINING PUT SHARES")
multiplied by the Old Bid Price, divided by the New Bid Price, and (ii) the
Remaining Put Shares.

        Section 2.7 MINIMUM COMMITMENT. If the Company for any reason fails to
issue and deliver such Put Shares equal to or exceeding the Minimum Commitment
Amount during the Commitment Period, then on the first business day after the
expiration of the Commitment Period, the Company shall issue to the Investor
warrants to purchase a number of shares equal to the number of Warrants that
would be issuable pursuant to Section 2.4 in respect of the Minimum Commitment
Amount divided by the Bid Price. Such warrants shall be for the period of four
(4) four years, shall have cashless exercise provisions, and shall be deemed
shares under the Registration Rights Agreement annexed hereto, and shall be
exercisable at a price equal to one hundred twenty-five (125%) percent of the
Bid Price on the date issued.

    Section 2.8 LIQUIDATED DAMAGES. Each of the Company and Investor acknowledge
and agree that the sums payable under Section 2.1(b) and Section 2.7 and the
requirement to issue Blackout Shares under Section 2.6 shall give rise to
liquidated damages and not penalties. Each of the Company and Investor further
acknowledge that (a) the amount of loss or damages likely to be incurred is
incapable or is difficult to precisely estimate, (b) the amounts specified in
such Sections bear a reasonable proportion and are not plainly or grossly
disproportionate to the probable loss likely to be incurred by Investor in
connection with the failure by the Company to make Puts with aggregate Purchase
Prices totaling at least the Minimum Commitment Amount or in connection with a
Blackout Period under the Registration Rights Agreement, and (c) each of the
Company and Investor are sophisticated business parties and have been
represented by sophisticated and able legal and financial counsel and negotiated

effectiveness of any Registration Statement or the initiation of any proceedings
for that purpose; (c) receipt of any notification with respect to the suspension

proceeding for such purpose; (d) the happening of any event that makes any
statement made in such Registration Statement or related prospectus or any
document incorporated or deemed to be incorporated therein 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
a 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 (e) the Company's reasonable

after the commencement of each calendar quarter occurring subsequent to the
commencement of the Commitment Period, the Company undertakes to notify Investor
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 with
respect to such calendar quarter and shall in no way obligate the Company to
raise such amount during such calendar quarter or otherwise limit its ability to
deliver Put Notices during such calendar quarter. The failure by the

<PAGE>   24

Company to comply with this provision can be cured by the Company's notifying
Investor at any time as to its reasonable expectations with respect to the
current calendar quarter.

        Section 6.10 CONSOLIDATION; MERGER. The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with or

such shares of Common Stock and/or securities as Investor is entitled to receive
pursuant to this Agreement.

        Section 6.11 ISSUANCE OF PUT SHARES AND BLACKOUT SHARES. The sale of the

investigation brought by the SEC against or involving the Company or in
connection with or as a result of the consummation of the transactions
contemplated by the Transaction Documents, or if Investor is impleaded in any
such action, proceeding or investigation by any person, then in any such case,
the Company will reimburse Investor for its reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith, as such expenses are incurred. In addition, other than with respect
to any matter in which Investor is a named party, the Company will pay to
Investor the charges, as reasonably determined by Investor, for the time of any
officers or employees of Investor devoted to appearing and preparing to appear
as witnesses, assisting in preparation for hearings, trials or pretrial matters,

        Section 6.13 DILUTION. The number of shares of Common Stock issuable as
Put Shares may increase substantially in certain circumstances, including, but
not necessarily limited to, the circumstance wherein the trading price of the
Common Stock declines during the period between the Effective Date and the end
of the Commitment Period. The Company's executive officers and directors have
studied and fully understand the nature of the transactions contemplated by this
Agreement and recognize that they have a potential dilutive effect. The board of
directors of the Company has concluded, in its good faith business judgment,
that such issuance is in the best interests of the Company. The Company
specifically acknowledges that its obligation to issue the Put Shares is binding
upon the Company and enforceable regardless of the dilution such issuance may
have on the ownership interests of other shareholders of the Company.

    Section 6.14 USE OF PROCEEDS. The Company will use the proceeds received
hereunder (excluding amounts paid by the Company for legal fees, finder's fees
and escrow fees in connection with the sale of the Common Stock) for internal
working capital purposes, and, unless specifically consented to in advance in
each instance by the Investor, which consent shall not be unreasonably withheld,
the Company shall not, directly or indirectly, use such proceeds for any loan to
or investment in any other corporation, partnership enterprise or other person
or for the repayment of any outstanding loan by the Company to any other party.

        Section 6.15 CERTAIN AGREEMENTS. (i) The Company covenants and agrees
that it will not, without the prior written consent of the Investor, enter into
any subsequent or further offer or sale of Common Stock or Common Stock
Equivalents (collectively, "New Common Stock") with any third party pursuant to
a transaction which in any manner permits the sale of the New Common Stock on
any date which is thirty (30) days prior or subsequent to any Additional Closing
Date.

               (ii) The provisions of subparagraph 6.15(i) will not apply to (w)
Common Stock issued pursuant to an exemption from registration under the
Securities Act of 1933; (x) an underwritten public offering of shares of Common
Stock or Preferred Stock; (y) an offering of convertible Preferred Stock at
market or above; or (z) the issuance of securities (other than for cash) in
connection with an acquisition, merger, consolidation, sale of assets,
disposition or the exchange of the capital stock for assets, stock or other
joint venture interests.

               (iii) In the event the Company breaches the provisions of this
Section , the Discount (as defined in shall be amended to be equal to (x)110% of
the Discount set forth herein and the Investor may terminate its obligations
under this Agreement and demand such amounts as may be owing under Section 2.7.

satisfied and complied in all respects with all covenants, agreements and

Initial Registrable Securities by Investor and such Registration Statement shall
have been declared effective by the SEC prior to the first Put Date, and in any

Statement. For the purposes of any Put Notice with respect to the Registrable
Securities other than the Initial Registrable Securities, the Company shall have

Registrable Securities by Investor which shall have been declared effective by
the SEC prior to the Put Date therefor.

               (b) EFFECTIVE REGISTRATION STATEMENT. As set forth in the
Registration Rights Agreement, a Registration Statement shall have previously
become effective for the resale by Investor of the Registrable Securities
subject to such Put Notice and such Registration Statement shall remain
effective on each Condition Satisfaction Date and (i) neither the Company nor
Investor shall have received notice that the SEC has issued or intends to issue
a stop order with respect to such Registration Statement or that the SEC
otherwise has suspended or withdrawn the effectiveness of such Registration
Statement, either temporarily or permanently, or intends or has threatened to do
so (unless the SEC's concerns have been addressed and Investor is reasonably
satisfied that the SEC no longer is considering or intends to take such
action),and (ii) no other suspension of the use or withdrawal

<PAGE>   27

of the effectiveness of such Registration Statement or related prospectus shall

               (c) ACCURACY OF THE COMPANY'S REPRESENTATIONS AND WARRANTIES. The
representations and warranties of the Company shall be true and correct in all
material respects as of each Condition Satisfaction Date as though made at each
such time (except for representations and warranties specifically made as of a
particular date) with respect to all periods, and as to all events and
circumstances occurring or existing to and including each Condition Satisfaction
Date, except for any conditions which have temporarily caused any
representations or warranties herein to be incorrect and which have been
corrected with no continuing impairment to the Company or Investor.

               (d) PERFORMANCE BY THE COMPANY. The Company shall have performed,
satisfied and complied in all material respects with all covenants, agreements
and conditions required by this Agreement and the Registration Rights Agreement

decree, ruling or injunction shall have been enacted, entered, promulgated or
adopted by any court or governmental authority of competent jurisdiction that

Registration Statement, opinions of the Company's legal counsel in the form of
Exhibits C-1 and C-2 hereto, addressed to Investor.

               (i) DUE DILIGENCE. No dispute between the Company and Investor
shall exist pursuant to Section 7.3 as to the adequacy of the disclosure
contained in any Registration Statement.

               (j) TEN PERCENT LIMITATION. On each Closing Date, the number of
Put Shares then to be purchased by Investor shall not exceed the number of such
shares that, when aggregated with all other shares of

<PAGE>   28

Registrable Securities then owned by Investor beneficially or deemed
beneficially owned by Investor, would result in Investor owning no more than
[9.9%] of all of such Common Stock as would be outstanding on such Closing Date,
as determined in accordance with Section 16 of the Exchange Act and the
regulations promulgated thereunder. For purposes of this Section 7.2(j), in the
event that the amount of Common Stock outstanding as determined in accordance
with Section 16 of the Exchange Act and the regulations promulgated thereunder
is greater on a Closing Date than on the date upon which the Put Notice
associated with such Closing Date is given, the amount of Common Stock
outstanding on such Closing Date shall govern for purposes of determining

reduced by ten (10%) percent from the Investment Amount set forth in the Put
Notice.

               (l) NO KNOWLEDGE. The Company shall have no knowledge of any
event more likely than not to have the effect of causing such Registration
Statement to be suspended or otherwise ineffective (which event is more likely
than not to occur within the fifteen Trading Days following the Trading Day on
which such Notice is deemed delivered).

               (m) TRADING CUSHION. The Trading Cushion shall have elapsed since
the immediately preceding Put Date.

               (n) SHAREHOLDER VOTE. The issuance of shares of Common Stock with
respect to the applicable Closing, if any, shall not violate the shareholder
approval requirements of the Principal Market.

since the Put Date.

               (p) OTHER. On each Condition Satisfaction Date, Investor shall
have received and been reasonably satisfied with such other certificates and
documents as shall have been reasonably requested by Investor in order for
Investor to confirm the Company's satisfaction of the conditions set forth in
this Section 7.2., including, without limitation, a certificate in substantially
the form and substance of Exhibit D hereto, executed by an executive officer of
the Company and to the effect that all the conditions to such Closing shall have
been satisfied as at the date of each such certificate.

        Section 7.3 DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC
INFORMATION.

<PAGE>   29

               (a) The Company shall make available for inspection and review by
Investor, advisors to and representatives of Investor (who may or may not be
affiliated with Investor and who are reasonably acceptable to the Company), any
Underwriter, any Registration Statement or amendment or supplement thereto or
any blue sky, NASD or other filing, all financial and other records, all SEC
Documents and other filings with the SEC, and all other corporate documents and
properties of the Company as may be reasonably necessary for the purpose of such
review, and cause the Company's officers, directors and employees to supply all
such information reasonably requested by Investor or any such representative,
advisor or Underwriter in connection with such Registration Statement
(including, without limitation, in response to all questions and other inquiries
reasonably made or submitted by any of them), prior to and from time to time
after the filing and effectiveness of such Registration Statement for the sole
purpose of enabling Investor and such representatives, advisors and Underwriters
and their respective accountants and attorneys to conduct initial and ongoing
due diligence with respect to the Company and the accuracy of such Registration
Statement.

               (b) Each of the Company, its officers, directors, employees and
agents shall in no event disclose non-public information to Investor, advisors
to or representatives of Investor, unless prior to disclosure of such
information the Company identifies such information as being non-public
information and provides Investor, such advisors and representatives with the
opportunity to accept or refuse to accept such non-public information for
review. The Company may, as a condition to disclosing any non-public information
hereunder, require Investor's advisors and representatives to enter into a
confidentiality agreement in form and substance reasonably satisfactory to the
Company and Investor.

               (c) Nothing herein shall require the Company to disclose
non-public information to Investor or its advisors or representatives, and the
Company represents that it does not disseminate non-public information to any
investors who purchase stock in the Company in a public offering, to money
managers or to securities analysts; provided, however, that notwithstanding
anything herein to the contrary, the Company shall, as hereinabove provided,
immediately notify the advisors and representatives of Investor and any
Underwriters of any event or the existence of any circumstance(without any
obligation to disclose the specific event or circumstance) of which it becomes
aware, constituting non-public information (whether or not requested of the
Company specifically or generally during the course of due diligence by such
persons or entities), which, if not disclosed in the prospectus included in a
Registration Statement would cause such prospectus to include a material
misstatement or to omit a material fact required to be stated therein in order
to make the statements therein, in light of the circumstances in which they were
made, not misleading. Nothing contained in this Section 7.3 shall be construed
to mean that such persons or entities other than Investor (without the written
consent of Investor prior to disclosure of such information) may not obtain
non-public

<PAGE>   30

information in the course of conducting due diligence in accordance with the
terms and conditions of this Agreement and nothing herein shall prevent any such
persons or entities from notifying the Company of their opinion that based on
such due diligence by such persons or entities, any Registration Statement
contains an untrue statement of a material fact or omits a material fact
required to be stated in such Registration Statement or necessary to make the
statements contained therein, in light of the circumstances in which they were
made, not misleading.

                                  ARTICLE VIII

                                     LEGENDS

               Section 8.1 LEGENDS. Unless otherwise provided below, each
certificate representing Registrable Securities will bear the following
legend(the "LEGEND"):

               The securities represented by this certificate have not been
               registered under the Securities Act of 1933 (the "Securities
               Act") or qualified under applicable state securities laws. These
               securities may not be offered, sold, pledged, hypothecated,
               transferred or otherwise disposed of except pursuant to (I) an
               effective registration statement and qualification in effect with
               respect thereto under the Securities Act and under any applicable
               state securities law, (ii) to the extent applicable, Rule 144
               under the Securities Act, or (iii) an opinion of counsel
               reasonably acceptable to the Company that such registration and
               qualification is not required under applicable federal and state
               securities laws."

As soon as practicable after the execution and delivery hereof, the Company
shall issue to the Transfer Agent Instructions in substantially the form of
Exhibit E hereto. Such instructions shall be irrevocable by the Company from and
after the date thereof or from and after the issuance thereof except as
otherwise expressly provided in the Registration Rights Agreement. It is the
intent and purpose of such instructions, as provided therein, to require the
Transfer Agent to issue to Investor certificates evidencing shares of Common
Stock incident to a Closing, free of the Legend, without consultation by the
transfer agent with the Company or its counsel and without the need for any
further advice or instruction or documentation to the Transfer Agent by or from
the Company or its counsel or Investor; provided that(a) a Registration
Statement shall then be effective, (b) Investor confirms to the Transfer Agent
and the Company that it has or intends to sell such Common Stock to a third
party which is not an affiliate of Investor or the Company and Investor agrees
to redeliver the certificate representing such shares of Common Stock to the
Transfer Agent to add the Legend in the event the Common Stock is not sold, and
(c) if reasonably requested by the transfer agent or the Company, Investor

<PAGE>   31

confirms to the transfer agent and the Company that Investor has complied with
the prospectus delivery requirement under the Securities Act. At any time after
the Effective Date, upon surrender of one or more certificates evidencing Common
Stock that bear the Legend, to the extent accompanied by a notice requesting the
issuance of new certificates free of the Legend to replace those surrendered.

        Section 8.2 NO OTHER LEGEND OR STOCK TRANSFER RESTRICTIONS. No legend
other than the one specified in Section 8.1 has been or shall be placed on the
share certificates representing the Common Stock and no instructions or"stop
transfers orders," so called, "stock transfer restrictions," or other
restrictions have been or shall be given to the Company's transfer agent with
respect thereto other than as expressly set forth in this Article VIII.

        Section 8.3 INVESTOR'S COMPLIANCE. Nothing in this Article VIII shall
affect in any way Investor's obligations under any agreement to comply with all
applicable securities laws upon resale of the Common Stock.

        Section 8.4 OFFSHORE TRANSACTIONS. Subject to the completeness and
accuracy of the Buyer's representations and warranties herein, upon request of
an investor who is a non-U.S. Person, and following the expiration of any
applicable Distribution Compliance Period (as those terms are defined in
Regulation S), the Company, shall, at its expense, take all necessary action
(including the issuance of an opinion of counsel) to assure that the Company's
transfer agent shall issue stock certificates without restrictive legend or stop
orders in the name of Investor (or its nominee (being a non-U.S. Person) or such
non-U.S. Persons as may be designated by Investor. Nothing in this Section,
however, shall affect in any way Investor's or such nominee's obligations and
agreement to comply with all applicable securities laws upon resale of the
Common Stock.

        Section 9.2  INDEMNIFICATION.

               The Company agrees to indemnify and hold harmless Investor and
its officers, directors, employees, and agents, and each Person or entity, if
any, who controls Investor within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, together with the Controlling Persons (as
defined in the Registration Rights Agreement) from and against any Damages,
joint or several, and any action in respect thereof to which Investor, its
partners, affiliates, officers, directors, employees, and duly authorized
agents, and any such Controlling Person becomes subject to, resulting from,
arising out of or relating to any misrepresentation, breach of warranty or
nonfulfillment of or failure to perform any covenant or agreement on the part of
Company contained in this Agreement, as such Damages are incurred, except to the
extent such Damages result primarily from Investor's failure to perform any
covenant or agreement contained in this Agreement or Investor's or its
officer's, director's, employee's, agent's or Controlling Person's negligence,
recklessness or bad faith in performing its obligations under this Agreement.

        Section 9.3 METHOD OF ASSERTING INDEMNIFICATION CLAIMS. All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.2
shall be asserted and resolved as follows:

               (a) In the event any claim or demand in respect of which any
person claiming indemnification under any provision of Section 9.2
(an"INDEMNIFIED PARTY") might seek indemnity under Section 9.2 is asserted
against or sought to be collected from such Indemnified Party by a person other
than a party hereto or an affiliate thereof (a "THIRD PARTY CLAIM"), the
Indemnified Party shall deliver a written notification, enclosing a copy of all
papers served, if any, and specifying the nature of and basis for such Third
Party Claim and for the Indemnified Party's claim for indemnification that is
being asserted under any provision of Section 9.2 against any person
(the"INDEMNIFYING PARTY"), together with the amount or, if not then reasonably
ascertainable, the estimated amount, determined in good faith, of such Third
Party Claim (a "CLAIM NOTICE") with reasonable promptness to the Indemnifying
Party. If the Indemnified Party fails to provide the Claim Notice with
reasonable promptness after the Indemnified Party receives notice of such Third
Party Claim, the Indemnifying Party shall not be obligated to indemnify the
Indemnified Party with respect to such Third Party Claim to the extent that the
Indemnifying Party's ability to defend has been prejudiced by such failure of
the Indemnified Party. The Indemnifying Party shall notify the Indemnified Party
as soon as practicable within the period ending thirty (30) calendar days
following receipt by the Indemnifying Party of either a Claim Notice or an
Indemnity Notice (as defined below) (the "DISPUTE PERIOD") whether the
Indemnifying Party disputes its liability or the amount of its liability to the
Indemnified Party under Section 9.2 and whether the Indemnifying Party desires,
at its sole cost and expense, to defend the Indemnified

<PAGE>   34

Party against such Third Party Claim. (i) If the Indemnifying Party notifies the
Indemnified Party within the Dispute Period that the Indemnifying Party desires
to defend the Indemnified Party with respect to the Third Party Claim pursuant
to this Section 9.3(a), then the Indemnifying Party shall have the right to
defend, with counsel reasonably satisfactory to the Indemnified Party, at the
sole cost and expense of the Indemnifying Party, such Third Party Claim by all
appropriate proceedings, which proceedings shall be vigorously and diligently
prosecuted by the Indemnifying Party to a final conclusion or will be settled at
the discretion of the Indemnifying Party (but only with the consent of the
Indemnified Party in the case of any settlement that provides for any relief
other than the payment of monetary damages or that provides for the payment of
monetary damages as to which the Indemnified Party shall not be indemnified in
full pursuant to Section 9.2). The Indemnifying Party shall have full control of
such defense and proceedings, including any compromise or settlement thereof;
provided, however, that the Indemnified Party may, at the sole cost and expense
of the Indemnified Party, at any time prior to the Indemnifying Party's delivery
of the notice referred to in the first sentence of this clause (i), file any
motion, answer or other pleadings or take any other action that the Indemnified
Party reasonably believes to be necessary or appropriate to protect its
interests; and provided further, that if requested by the Indemnifying Party,
the Indemnified Party will, at the sole cost and expense of the Indemnifying
Party, provide reasonable cooperation to the Indemnifying Party in contesting
any Third Party Claim that the Indemnifying Party elects to contest. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
clause (i), and except as provided in the preceding sentence, the Indemnified
Party shall bear its own costs and expenses with respect to such participation.
Notwithstanding the foregoing, the Indemnified Party may takeover the control of
the defense or settlement of a Third Party Claim at any time if it irrevocably
waives its right to indemnity under Section 9.2 with respect to such Third Party
Claim. (ii) If the Indemnifying Party fails to notify the Indemnified Party
within the Dispute Period that the Indemnifying Party desires to defend the
Third Party Claim pursuant to Section 9.3(a), or if the Indemnifying Party gives
such notice but fails to prosecute vigorously and diligently or settle the Third
Party Claim, or if the Indemnifying Party fails to give any notice whatsoever
within the Dispute Period, then the Indemnified Party shall have the right to
defend, at the sole cost and expense of the Indemnifying Party, the Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted by
the Indemnified Party in a reasonable manner and in good faith or will be
settled at the discretion of the Indemnified Party(with the consent of the
Indemnifying Party, which consent will not be unreasonably withheld). The
Indemnified Party will have full control of such defense and proceedings,
including any compromise or settlement thereof; provided, however, that if
requested by the Indemnified Party, the Indemnifying Party will, at the sole
cost and expense of the Indemnifying Party, provide reasonable cooperation to
the Indemnified Party and its counsel in contesting any Third Party Claim which
the Indemnified Party is contesting. Notwithstanding the foregoing

<PAGE>   35

provisions of this clause (ii), if the Indemnifying Party has notified the
Indemnified Party within the Dispute Period that the Indemnifying Party disputes
its liability or the amount of its liability hereunder to the Indemnified Party
with respect to such Third Party Claim and if such dispute is resolved in favor
of the Indemnifying Party in the manner provided in clause(iii) below, the
Indemnifying Party will not be required to bear the costs and expenses of the
Indemnified Party's defense pursuant to this clause (ii) or of the Indemnifying
Party's participation therein at the Indemnified Party's request, and the
Indemnified Party shall reimburse the Indemnifying Party in full for all
reasonable costs and expenses incurred by the Indemnifying Party in connection
with such litigation. The Indemnifying Party may participate in, but not
control, any defense or settlement controlled by the Indemnified Party pursuant
to this clause (ii), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation. (iii) If the Indemnifying Party
notifies the Indemnified Party that it does not dispute its liability or the
amount of its liability to the Indemnified Party with respect to the Third Party
Claim under Section 9.2 or fails to notify the Indemnified Party within the
Dispute Period whether the Indemnifying Party disputes its liability or the
amount of its liability to the Indemnified Party with respect to such Third
Party Claim, the amount of Damages specified in the Claim Notice shall be
conclusively deemed a liability of the Indemnifying Party under Section 9.2 and
the Indemnifying Party shall pay the amount of such Damages to the Indemnified
Party on demand. If the Indemnifying Party has timely disputed its liability or
the amount of its liability with respect to such claim, the Indemnifying Party
and the Indemnified Party shall proceed in good faith to negotiate a resolution
of such dispute; provided, however, that if the dispute is not resolved within
thirty (30) days after the Claim Notice, the Indemnifying Party shall be
entitled to institute such legal action as it deems appropriate.

               (b) In the event any Indemnified Party should have a claim under
Section 9.2 against the Indemnifying Party that does not involve a Third Party
Claim, the Indemnified Party shall deliver a written notification of a claim for
indemnity under Section 9.2 specifying the nature of and basis for such claim,
together with the amount or, if not then reasonably ascertainable, the estimated
amount, determined in good faith, of such claim (an "INDEMNITY NOTICE") with
reasonable promptness to the Indemnifying Party. The failure by any Indemnified
Party to give the Indemnity Notice shall not impair such party's rights
hereunder except to the extent that the Indemnifying Party demonstrates that it
has been irreparably prejudiced thereby. If the Indemnifying Party notifies the
Indemnified Party that it does not dispute the claim or the amount of the claim
described in such Indemnity Notice or fails to notify the Indemnified Party
within the Dispute Period whether the Indemnifying Party disputes the claim or
the amount of the claim described in such Indemnity Notice, the amount of
Damages specified in the Indemnity Notice will be conclusively deemed a
liability of the Indemnifying Party under Section 9.2 and the Indemnifying Party
shall pay the amount of such Damages to the Indemnified Party on demand. If the
Indemnifying Party has timely disputed its liability or the amount of its
liability with respect

<PAGE>   36

to such claim, the Indemnifying Party and the Indemnified Party shall proceed in
good faith to negotiate a resolution of such dispute; provided, however, that if
the dispute is not resolved within thirty (30) days after the Claim Notice, the
Indemnifying Party shall be entitled to institute such legal action as it deems
appropriate.

               (c) The indemnity agreements contained herein shall be in
addition to (i) any cause of action or similar rights of the Indemnified Party
against the Indemnifying Party or others, and (ii) any liabilities the
Indemnifying Party may be subject to.

                                    ARTICLE X

                                  MISCELLANEOUS

        Section 10.1 GOVERNING LAW; JURISDICTION. This Agreement shall be
governed by and interpreted in accordance with the laws of the State of
California without regard to the principles of conflicts of law. Each of the
Company and Investor hereby submit to the exclusive jurisdiction of the United
States Federal and state courts located in California with respect to any
dispute arising under this Agreement, the agreements entered into in connection
herewith or the transactions contemplated hereby or thereby.

        Section 10.2 SPECIFIC ENFORCEMENT. The Company and the Investor
acknowledge and agree that irreparable damage would occur to the Investor in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the Investor shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Agreement and
to enforce specifically the terms and provisions hereof or thereof, this being
in addition to any other remedy to which any of them may be entitled by law or
equity.

        Section 10.3 ASSIGNMENT. This Agreement shall be binding upon and inure
to the benefit of the Company and Investor and their respective successors and
permitted assigns. Neither this Agreement nor any rights of Investor or the
Company hereunder may be assigned by either party to any other person.
Notwithstanding the foregoing, (a) the provisions of this Agreement shall inure
to the benefit of, and be enforceable by, any transferee of any of the Common
Stock purchased or acquired by Investor hereunder with respect to the Common
Stock held by such person, and (b) Investor's interest in this Agreement may be
assigned at any time, in whole but not in part, to any affiliate of Investor.

        Section 10.4 THIRD PARTY BENEFICIARIES. This Agreement is intended for
the benefit of the Company and Investor and their respective successors and
permitted assigns, and is not for the benefit of, nor may any provision hereof
be enforced by, any other person.

        Section 10.5 TERMINATION. This Agreement shall terminate twelve (12)
months after the commencement of the Commitment Period (unless extended by the
agreement of the Company and Investor); provided,

<PAGE>   37

however, that the provisions of Article VI, VIII, and Sections [10.1, 10.3, and
10.5] shall survive the termination of this Agreement.

        Section 10.6 ENTIRE AGREEMENT, AMENDMENT; NO WAIVER. This Agreement and
the instruments referenced herein contain the entire understanding of the
Company and Investor with respect to the matters covered herein and therein and,
except as specifically set forth herein or therein, neither the Company nor
Investor makes any representation, warranty, covenant or undertaking with
respect to such matters. No provision of this Agreement may be waived or amended
other than by an instrument in writing signed by the party to be charged with
enforcement.

        Section 10.7 FEES AND EXPENSES. Each of the Company and Investor agrees
to pay its own expenses in connection with the preparation of this Agreement and
performance of its obligations hereunder, except that the Company shall pay
Krieger & Prager, LLP the fee of $12,500 at the Initial Closing and $2,500 at
each subsequent Closing. In addition, the Company shall pay all reasonable fees
and expenses incurred by the Investor in connection with any amendments,
modifications or waivers of this Agreement or the Registration Rights Agreement
or incurred in connection with the enforcement of this Agreement and the
Registration Rights Agreement, including, without limitation, all reasonable
attorneys fees and expenses. The Company shall pay all stamp or other similar
taxes and duties levied in connection with issuance of the Shares pursuant
hereto.

        Section 10.8 NO BROKERS. Each of the Company and Investor represents
that it has had no dealings in connection with this transaction with any finder
or broker who will demand payment of any fee or commission from the other party,
except Grayson & Associates. The Company on the one hand, and Investor, on the
other hand, agree to indemnify the other against and hold the other harmless
from any and all liabilities to any persons claiming brokerage commissions or
finder's fees on account of services purported to have been rendered on behalf
of the indemnifying party in connection with this Agreement or the transactions
contemplated hereby.

        Section 10.9 COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which may be executed by less than all of the Company and
shall be deemed to be an original instrument which shall be enforceable against
the parties actually executing such counterparts and all of which together shall
constitute one and the same instrument. This Agreement, once executed by a
party, may be delivered to the other parties hereto by facsimile transmission of
a copy of this Agreement bearing the signature of the parties so delivering this
Agreement.

        Section 10.10 SURVIVAL; SEVERABILITY. The representations, warranties,
covenants and agreements of the Company hereto shall survive each Closing
hereunder for a period of one (1) year thereafter. In the event that any
provision of this Agreement becomes or is declared by a court of competent
jurisdiction to be illegal, unenforceable or void, this Agreement shall continue
in full force and effect without said provision; provided that such severability
shall be ineffective if it materially changes the economic benefit of this
Agreement to any party.

<PAGE>   38

        Section 10.11 FURTHER ASSURANCES. Each party shall do and perform, or
cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and
documents, as the other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

        Section 10.12 NO STRICT CONSTRUCTION. The language used in this
Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against
any party.

        Section 10.13 EQUITABLE RELIEF. The Company recognizes that in the event
that it fails to perform, observe, or discharge any or all of its obligations
under this Agreement, any remedy at law may prove to be inadequate relief to
Investor. The Company therefore agrees that Investor shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

        Section 10.14 TITLE AND SUBTITLES. The titles and subtitles used in this
Agreement are used for the convenience of reference and are not to be considered
in construing or interpreting this Agreement.

        Section 10.15 REPORTING ENTITY FOR THE COMMON STOCK. The reporting
entity relied upon for the determination of the trading price of the Common
Stock on any given Trading Day for the purposes of this Agreement shall be
Bloomberg L.P. or any successor thereto. The written mutual consent of Investor
and the Company shall be required to employ any other reporting entity.

        Section 10.16 PUBLICITY. The Company and Investor shall consult with
each other in issuing any press releases or otherwise making public statements
with respect to the transactions contemplated hereby and no party shall issue
any such press release or otherwise make any such public statement without the
prior written consent of the other parties, which consent shall not be
unreasonably withheld or delayed, except that no prior consent shall be required
if such disclosure is required by law, in which such case the disclosing party
shall provide the other parties with prior notice of such public statement.
Notwithstanding the foregoing, the Company shall not publicly disclose the name
of Investor without the prior written consent of such Investor, except to the
extent required by law. Investor acknowledges that this Agreement and all or
part of the Transaction Documents may be deemed to be "material contracts" as
that term is defined by Item 601(b)(10) of Regulation S-K, and that the Company
may therefore be required to file such documents as exhibits to reports or
registration statements filed under the Securities Act or the Exchange Act.
Investor further agrees that the status of such documents and materials as
material contracts shall be determined solely by the Company, in consultation
with its counsel.
