listed on Schedule 4.1 hereto.

                  4.2 Authorization. The Company has full power and authority

significantly affect the Company's internal controls. The Company maintains and
will continue to maintain a standard system of accounting established and
administered in accordance with GAAP and the applicable requirements of the 1934

set forth in Section 6.2 or 6.4, respectively, shall have become incapable of

                                    (iii) By an Investor (with respect to itself

                  7.2 [reserved]

                  7.3 No Conflicting Agreements. The Company will not take any

decrees of all governmental authorities.

                  7.6 Listing of Underlying Shares and Related Matters. Promptly
following the date hereof, the Company shall take all necessary action to cause
(i) the Initial Shares and the Initial Warrant Shares to be listed on the Nasdaq
Global Market no later than the First Closing Date and (ii) the Remaining Shares
and the Remaining Warrant Shares to be listed on the Nasdaq Global Market no
later than the Second Closing Date. Further, if the Company applies to have its

and will take such other action as is necessary to cause such Common Stock to be
so listed. The Company will use commercially reasonable efforts to continue the
listing and trading of its Common Stock on the Nasdaq Global Market and, in
accordance, therewith, will use commercially reasonable efforts to comply in all
respects with the Company's reporting, filing and other obligations under the
Amended and Restated Bylaws or rules of such market or exchange, as applicable.

                  7.7 Termination of Covenants. The provisions of Sections 7.2
through 7.5 shall terminate and be of no further force and effect on the date on
which the Company's obligations under the Registration Rights Agreement to
register or maintain the effectiveness of any registration covering the
Registrable Securities (as such term is defined in the Registration Rights
Agreement) shall terminate.

                  7.8 Removal of Legends. Upon the earlier of (i) registration
for resale pursuant to the Registration Rights Agreement or (ii) Rule 144(k)
becoming available, the Company shall (A) deliver to the transfer agent for the
Common Stock (the "Transfer Agent") irrevocable instructions that the Transfer
Agent shall reissue a certificate representing shares of Common Stock without
legends upon receipt by such Transfer Agent of the legended certificates for
such shares, together with either (1) a customary representation by the Investor
that Rule 144(k) applies to the shares of Common Stock represented thereby or
(2) a statement by the Investor that such Investor has sold the shares of Common
Stock represented thereby in accordance with the Plan of Distribution contained
in the Registration Statement, and (B) cause its counsel to deliver to the
Transfer Agent one or more blanket opinions to the effect that the removal of
such legends in such circumstances may be effected under the 1933 Act. From and
after the earlier of such dates, upon an Investor's written request, the Company
shall promptly cause certificates evidencing the Investor's Securities to be
replaced with certificates which do not bear such restrictive legends, and


                                       22


Warrant Shares subsequently issued upon due exercise of the Warrants shall not
bear such restrictive legends provided the provisions of either clause (i) or
clause (ii) above, as applicable, are satisfied with respect to such Warrant
Shares. When the Company is required to cause unlegended certificates to replace
previously issued legended certificates, if unlegended certificates are not
delivered to an Investor within five (5) Business Days of submission by that
Investor of legended certificate(s) to the Transfer Agent as provided above (or
to the Company, in the case of the Warrants), the Company shall be liable to the
Investor for liquidated damages in an amount equal to 1.5% of the aggregate
purchase price of the Securities evidenced by such certificate(s) for each
thirty (30) day period (or portion thereof) beyond such three (3) Business Day
that the unlegended certificates have not been so delivered.

                  7.9 Proxy Statement; Stockholders Meeting. (a) Promptly
following the execution and delivery of this Agreement the Company shall take
all action necessary to call a meeting of its stockholders (the "Stockholders
Meeting"), which shall occur not later than May 15, 2007 (the "Stockholders
Meeting Deadline"), for the purpose of seeking approval of the Company's
stockholders for (i) the issuance and sale to the Investors of the Remaining
Securities and (ii) the full adjustment of the Warrants in accordance with the
provisions of Section 8(f)(8) thereof (collectively, the "Proposals"). In
connection therewith, the Company will promptly prepare and file with the SEC
proxy materials (including a proxy statement and form of proxy) for use at the
Stockholders Meeting and, after receiving and promptly responding to any
comments of the SEC thereon, shall promptly mail such proxy materials to the
stockholders of the Company. Each Investor shall promptly furnish in writing to
the Company such information relating to such Investor and its investment in the
Company as the Company may reasonably request for inclusion in the Proxy
Statement, which information shall not contain any untrue statement of material
fact or omit to state any material fact necessary in order to make the
statements made therein not false or misleading. The Company will comply with
Section 14(a) of the 1934 Act and the rules promulgated thereunder in relation
to any proxy statement (as amended or supplemented, the "Proxy Statement") and
any form of proxy to be sent to the stockholders of the Company in connection
with the Stockholders Meeting, and the Proxy Statement shall not, on the date
that the Proxy Statement (or any amendment thereof or supplement thereto) is
first mailed to stockholders or at the time of the Stockholders Meeting, contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements made therein not false or misleading,
or omit to state any material fact necessary to correct any statement in any
earlier communication with respect to the solicitation of proxies or the
Stockholders Meeting which has become false or misleading. If the Company should
discover at any time prior to the Stockholders Meeting, any event relating to
the Company or any of its Subsidiaries or any of their respective affiliates,
officers or directors that is required to be set forth in a supplement or
amendment to the Proxy Statement, in addition to the Company's obligations under
the 1934 Act, the Company will promptly inform the Investors thereof.

                  (b) Subject to their fiduciary obligations under applicable
law (as determined in good faith by the Company's Board of Directors after
consultation with the Company's outside counsel), the Company's Board of
Directors shall recommend to the Company's stockholders that the stockholders
(and, subject to their fiduciary obligations, not revoke or amend such
recommendation) vote in favor of the Proposals (the "Company Board


                                       23


Recommendation") and shall cause the Company to take all commercially reasonable
action (including, without limitation, the hiring of a proxy solicitation firm
of nationally recognized standing) to solicit the approval of the stockholders
for the Proposals unless the Board of Directors shall have modified, amended or
withdrawn the Company Board Recommendation pursuant to the provisions of the
immediately succeeding sentence. Whether or not the Company's Board of Directors
determines at any time after the date hereof that, due to its fiduciary duties,
it must revoke or amend its recommendations to the Company's stockholders, the
Company shall take all commercially reasonable action necessary to convene the
Stockholders Meeting as promptly as practicable, but no later than the
Stockholders Meeting Deadline, to consider and vote upon the approval of the
Proposals.

                  7.10 Update of Disclosure Schedules. During the period
commencing immediately after the First Closing and ending on the earlier of the
Second Closing Date or the termination of this Agreement in accordance with its
terms (the "Updating Period"), the Company shall promptly notify the Investors
in writing if the Company becomes aware of the occurrence or non-occurrence of
any event during the Updating Period or the existence of any fact or condition
arising during the Updating Period that would cause or constitute a breach of
any of its representations or warranties contained herein had such
representation or warranty been made as of the time of the Company's discovery
of such event, fact or condition. Should any such event, fact or condition
require any change to the Disclosure Schedules, the Company shall promptly, and
in any event prior to the Second Closing Date deliver to the Investors a
supplement to the Disclosure Schedules specifying such change. In the event that
the Company delivers one or more supplements to the Disclosure Schedules
pursuant to this Section 7.10 that reflect any events, facts or conditions
which, in the good faith judgment of an Investor, constitute a Material Adverse
Effect, individually or in the aggregate, such Investor shall have the right to
terminate its obligations to effect the Second Closing in accordance with the
provisions of Section 6.5 hereof. Any Investor that does not exercise its right
to terminate this Agreement on the basis of such supplemental Disclosure
Schedules shall be deemed to have accepted such supplemented Disclosure
Schedules and the delivery of any such supplement will be deemed to have cured
any misrepresentation or breach of representation, warranty or covenant that
otherwise might have existing hereunder by reason of such events, fact or
condition, but only with respect to the Second Closing. In no event shall any
updating of the Disclosure Schedules cure or be deemed to cure any breach of a
representation or warranty existing as of the First Closing Date.

         8.       Survival and Indemnification.

                  8.1 Survival. The representations, warranties, covenants and
agreements contained in this Agreement shall survive the Closing of the
transactions contemplated by this Agreement.

                  8.2 Indemnification. The Company agrees to indemnify and hold
harmless each Investor and its Affiliates and their respective directors,
officers, employees and agents from and against any and all losses, claims,
damages, liabilities and expenses (including without limitation reasonable
attorney fees and disbursements and other expenses incurred in connection with
investigating, preparing or defending any action, claim or proceeding, pending
or threatened and the costs of enforcement thereof) (collectively, "Losses") to
which such Person may become subject as a result of any breach of
representation, warranty, covenant or agreement made by or to be performed on
the part of the Company under the Transaction Documents, and will reimburse any
such Person for all such amounts as they are incurred by such Person; provided
however that any Losses relating to the transactions contemplated by the
Registration Rights Agreement and covered by the indemnification contained
therein shall be indemnified in accordance with the Registration Rights
Agreement.


                                       24


                  8.3 Conduct of Indemnification Proceedings. Promptly after
receipt by any Person (the "Indemnified Person") of notice of any demand, claim
or circumstances which would or might give rise to a claim or the commencement
of any action, proceeding or investigation in respect of which indemnity may be
sought pursuant to Section 8.2, such Indemnified Person shall promptly notify
the Company in writing and the Company shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Person, and shall assume the payment of all fees and expenses; provided,
however, that the failure of any Indemnified Person so to notify the Company
shall not relieve the Company of its obligations hereunder except to the extent
that the Company is materially prejudiced by such failure to notify. In any such
proceeding, any Indemnified Person shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person unless: (i) the Company and the Indemnified Person shall
have mutually agreed to the retention of such counsel; or (ii) in the reasonable
judgment of counsel to such Indemnified Person representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. The Company shall not be liable for any settlement of
any proceeding effected without its written consent, which consent shall not be
unreasonably withheld, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Company shall indemnify and hold harmless such
Indemnified Person from and against any loss or liability (to the extent stated
above) by reason of such settlement or judgment. Without the prior written
consent of the Indemnified Person, which consent shall not be unreasonably
withheld, the Company shall not effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Person from all liability arising out of such proceeding.

         9.       Miscellaneous.

                  9.1 Successors and Assigns. This Agreement may not be assigned
by a party hereto without the prior written consent of the Company or the
Investors, as applicable, provided, however, that an Investor may assign its
rights and delegate its duties hereunder in whole or in part to an Affiliate or
to a third party acquiring some or all of its Securities in a private
transaction without the prior written consent of the Company or the other
Investors, after notice duly given by such Investor to the Company provided,
that no such assignment or obligation shall affect the obligations of such
Investor hereunder. The provisions of this Agreement shall inure to the benefit
of and be binding upon the respective permitted successors and assigns of the
parties. Nothing in this Agreement, express or implied, is intended to confer
upon any party other than the parties hereto or their respective successors and
assigns any rights, remedies, obligations, or liabilities under or by reason of
this Agreement, except as expressly provided in this Agreement.

the Company or the Investors without the prior consent of the Company (in the

and thereof.

                  9.10 Further Assurances. The parties shall execute and deliver
all such further instruments and documents and take all such other actions as

Trial. This Agreement shall be governed by, and construed in accordance with,
the internal laws of the State of New York without regard to the choice of law

                  9.12 Independent Nature of Investors' Obligations and Rights.
The obligations of each Investor under any Transaction Document are several and
not joint with the obligations of any other Investor, and no Investor shall be
responsible in any way for the performance of the obligations of any other
Investor under any Transaction Document. The decision of each Investor to
purchase Securities pursuant to the Transaction Documents has been made by such
Investor independently of any other Investor. Nothing contained herein or in any
Transaction Document, and no action taken by any Investor pursuant thereto,
shall be deemed to constitute the Investors as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Investors are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents. Each
Investor acknowledges that no other Investor has acted as agent for such
Investor in connection with making its investment hereunder and that no Investor
will be acting as agent of such Investor in connection with monitoring its
investment in the Securities or enforcing its rights under the Transaction
Documents. Each Investor shall be entitled to independently protect and enforce
its rights, including, without limitation, the rights arising out of this
Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Investor to be joined as an additional party in any
proceeding for such purpose. The Company acknowledges that each of the Investors


                                       28


has been provided with the same Transaction Documents for the purpose of closing
a transaction with multiple Investors and not because it was required or
requested to do so by any Investor.

date first above written.
