nor any other person is under any obligation to register such Common Shares

Agreement, "Material Adverse Effect" means any material adverse effect on
the business, properties, assets, operations, results of operations or financial
condition of the Company and its Subsidiaries taken as a whole, or on the
transactions contemplated hereby or by the agreements and instruments to be

accounting requirements and the published rules and regulations of the SEC with

respect to the Transaction Documents and the transactions contemplated thereby.
The Company further acknowledges that each Investor is not acting as a financial
advisor or fiduciary of the Company (or in any similar capacity) with respect to
the Transaction Documents and the transactions contemplated thereby and any

its affiliates, nor any person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to

to be integrated with prior offerings by the Company for purposes of the 1933
Act or any applicable stockholder approval provisions, including, without
limitation, under the rules and regulations of the Nasdaq National Market, nor
will the Company or any of its Subsidiaries take any action or steps that would
require registration of any of the Common Shares under the 1933 Act or cause the
offering of the Common Shares to be integrated with other offerings.

m.Application of Takeover Protections. The Company and its
board of directors have taken all necessary action, if any, in order to render
inapplicable any control share acquisition, business combination, poison pill
(including any distribution under a rights agreement) or other similar anti-
takeover provision under the Certificate of Incorporation or the laws of the
state of its incorporation which is or could become applicable to the Investors
as a result of the Investors and the Company fulfilling their obligations under

of the Common Shares and the Investors' ownership of the Common Shares.

shall cause each of its subsidiaries and its and each of their respective
officers, directors, employees and agents, not to, provide any Investor with any
material nonpublic information regarding the Company or any of its subsidiaries
from and after the filing of the 8-K Filing with the SEC without the express
written consent of such Investor. In the event of a breach of the foregoing
covenant by the Company, any of its Subsidiaries, or any of its or their
respective officers, directors, employees and agents, in addition to any other
remedy provided herein, in the Transaction Documents, an Investor shall have the
right to make a public disclosure, in the form of a press release, public
advertisement or otherwise, of such material nonpublic information without the
prior approval by the Company, its subsidiaries, or any of its or their
respective officers, directors, employees or agents; provided that the Company
does not publicly disclose such information within 24 hours of such Investor (i)
notifying the Company of the breach of the immediately preceding sentence and
(ii) first providing the Company with such Investor's proposed form of
disclosure. Such Investor agrees to make any reasonable changes (determined in
such Investor's sole discretion) to such disclosure requested by the Company
within 24 hours of such Investor first providing the Company with such
Investor's proposed form of disclosure. No Investor shall have any liability to
the Company, its subsidiaries, or any of its or their respective officers,
directors, employees, shareholders or agents for any such disclosure. Subject to
the foregoing, neither the Company nor any Investor shall issue any press
releases or any other public statements with respect to the transactions
contemplated hereby; provided, however, that the Company shall be entitled,
without the prior approval of any Investor, to make any press release or other
public disclosure with respect to such transactions (i) in substantial
conformity with the 8-K Filing and contemporaneously therewith and (ii) as is
required by applicable law and regulations (provided that in the case of clause
(i) each Investor shall be consulted by the Company in connection with any such
press release or other public disclosure prior to its release).

(h)Prospectus Supplement. Within two (2) Business Days of
the filing with the SEC of the Form 8-K referred to in the first sentence of
Section 4(g), the Company shall file with the SEC, a prospectus supplement, in a
form reasonably acceptable to each Investor, to the prospectus for the Resale
Registration Statement disclosing the terms of this transaction and all other
information necessary to be included in a prospectus supplement to keep such
Resale Registration Statement current and available for use by the Investors for
the resale of the Warrant Shares. On or before the second Business Day following
the Closing Date, the Company shall deliver a copy of such prospectus supplement
to each Investor.

(i)Destroyed Notes. The Company acknowledges and agrees

7.INDEMNIFICATION. In consideration of each Investor's
execution and delivery of the Transaction Documents and permitting the
redemption and exchange of its Notes hereunder and in addition to all of the
Company's other obligations under the Transaction Documents, the Company shall
defend, protect, indemnify and hold harmless each Investor and each other holder
of the Common Shares and all of their stockholders, officers, directors,
employees and direct or indirect investors and any of the foregoing persons'
agents or other representatives (including, without limitation, those retained
in connection with the transactions contemplated by this Agreement)
(collectively, the "Indemnitees") from and against any and all actions,
causes of action and suits and from any claims, losses, costs, penalties, fees,
liabilities and damages, and expenses actually suffered or actually paid by such
Indemnitee in connection therewith (irrespective of whether any such Indemnitee
is a party to the action for which indemnification hereunder is sought), and
including reasonable attorneys' fees and disbursements (the "Indemnified
Liabilities"), incurred by any Indemnitee as a result of, or arising out of,
or relating to (a) any misrepresentation or breach of any representation or
warranty made by the Company in the Transaction Documents or any other
certificate, instrument or document contemplated thereby, provided such
Indemnitee notifies the Company of its claim for indemnification under this
Section 7 for such misrepresentation or breach of a representation or warranty
on or before the date which is one (1) year after the date of this Agreement,
(b) any breach of any covenant, agreement or obligation of the Company contained
in the Transaction Documents or any other certificate, instrument or document
contemplated thereby or (c) any cause of action, suit or claim brought or made
against such Indemnitee (other than a cause of action, suit or claim which is
(x) brought or made by the Company and (y) is not a shareholder derivative suit)
and arising out of or resulting from (i) the execution, delivery, performance or
enforcement of the Transaction Documents, (ii) any transaction financed or to be
financed in whole or in part, directly or indirectly, with the proceeds of the
issuance of the Common Shares or (iii) solely the status of such Investor
or holder of the Common Shares as an investor in the Company. To the extent that
the foregoing undertaking by the Company may be unenforceable for any reason,
the Company shall make the maximum contribution to the payment and satisfaction
of each of the Indemnified Liabilities which is permissible under applicable
law.

Any controversy, claim or dispute arising between the Company and an
Indemnitee concerning the existence, scope or amount of any Indemnified
Liability shall be determined by arbitration in the City of Chicago by one
arbitrator in accordance with the Commercial Arbitration Rules of the American
Arbitration Association (the "Arbitration Rules"). Such arbitrator shall
be selected by mutual agreement of the Company and such Indemnitee in accordance
with the Arbitration Rules. In the event the Company and such Indemnitee cannot
agree on the selection of the arbitrator within 30 days, the American
Arbitration Association shall nomination three persons. Each of the Company and
the Indemnitee shall be entitled to strike one of such three nominees on a
peremptory basis within 10 days after its receipt of such list of nominees,
indicating its order of preference with respect to the remaining nominees. If
two such nominees have been stricken by the parties, the unstricken nominee
shall be the arbitrator. Otherwise, the selection of the arbitrator shall be
made by the American Arbitration Association from the remaining nominees in
accordance with the parties' mutual order of preference, or by random selection
in the absence of a mutual order of preference. The arbitrator shall base its
award on applicable law and judicial precedent, shall include such award
findings of fact and conclusions of law upon which the award is based and shall
not grant any remedy or relief that a court could not grant under applicable
law. The arbitrator's award and findings shall be for purposes of this Section 7
only and shall not in any way limit or prejudice any other rights that the
Company or such Indemnitee under this Agreement or the other Transaction
Documents or under any applicable law. 

8.GOVERNING LAW; MISCELLANEOUS.

a.Governing Law; Jurisdiction; Jury Trial. The corporate
laws of the State of Delaware shall govern all issues concerning the relative
rights of the Company and its stockholders. All other questions concerning the
construction, validity, enforcement and interpretation of this Agreement shall
be governed by the internal laws of the State of New York, without giving effect
to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State of New York. Each party hereby
irrevocably submits to the non-exclusive jurisdiction of the state and federal
courts sitting in Cook County, the City of Chicago, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated
hereby or discussed herein, and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, that such suit, action or
proceeding is brought in an inconvenient forum or that the venue of such suit,
action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action
or proceeding by mailing a copy thereof to such party at the address for such
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any
manner permitted by law. Each party hereby irrevocably waives any right it may
have, and agrees not to request, a jury trial for the adjudication of any
dispute hereunder or in connection herewith or arising out of this Agreement or
any transaction contemplated hereby.

b.Counterparts. This Agreement may be executed in two or
more identical counterparts, all of which 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; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

c.Headings. The headings of this Agreement are for
convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement.

d.Severability. If any provision of this Agreement shall
be invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction.

e.Entire Agreement; Amendments. This Agreement, the
Registration Rights Agreement and the Warrant Amendment supersede all other
prior oral or written agreements between the Investors, the Company, their
affiliates and persons acting on their behalf with respect to the matters
discussed herein, and this Agreement and the instruments referenced herein
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Investor makes any representation,
warranty, covenant or undertaking with respect to such matters. Notwithstanding
the foregoing, the Securities Purchase Agreement, the First Registration Rights
Agreement and the Warrants, as amended by the Warrant Amendment, shall remain in
full force and effect with respect to any securities and the transactions
contemplated thereby. No provision of this Agreement may be amended other than
by an instrument in writing signed by the Company and the Investors which
received a majority of the Common Shares received on the Closing Date or, if
prior to the Closing Date, the Investors listed on the Schedule of Investors as
being obligated to tender and exchange a majority of the aggregate principal
amount of the Notes proposed to be redeemed and exchanged at the Closing. No
provision hereof may be waived other than by an instrument in writing signed by
the party against whom enforcement is sought. No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Common Shares or Warrants then outstanding. No consideration shall be offered or
paid to any person to amend or consent to a waiver or modification of any
provision of any of the Transaction Documents unless the same consideration also
is offered to all of the parties to the Transaction Documents or holders of the
Common Shares as the case may be.

f.Notices. Any notices, consents, waivers or other
communications required or permitted to be given under the terms of this
Agreement must be in writing and will be deemed to have been delivered (i) upon
receipt, when delivered personally; (ii) upon receipt, when sent by facsimile

g.Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
assigns, including any purchasers of the Warrants. The Company shall not assign
this Agreement or any rights without the prior written 

consent of each Investor. An Investor may assign some or all of its rights
hereunder without the consent of the Company, provided, however, that any such
assignment shall not release such Investor from its obligations hereunder unless
such obligations are assumed by such assignee and the Company has consented to
such assignment and assumption. Notwithstanding anything to the contrary
contained in the Transaction Documents, the Investors shall be entitled to
pledge the Common Shares in connection with a bona fide margin account or other
loan secured by such Common Shares.

h.No Third Party Beneficiaries. Except with respect to
Section 8(p), this Agreement is intended for the benefit of the parties hereto
and their respective permitted successors and assigns, and is not for the
benefit of, nor may any provision hereof be enforced by, any other person.

i.Survival. Unless this Agreement is terminated under
Section 8(k), the representations and warranties of the Company and the
Investors contained in Sections 2 and 3, the agreements and covenants set forth
in Sections 4 and 8, and the indemnification provisions set forth in Section 7,
shall survive the Closing. Each Investor shall be responsible only for its own
representations, warranties, agreements and covenants hereunder.

j.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.

k.Termination. In the event that the Closing shall not
have occurred with respect to an Investor on or before three (3) Business Days
from the date hereof due to the Company's or the Investor's failure to satisfy
the conditions set forth in Sections 5 and 6 above (and the non-breaching
party's failure to waive such unsatisfied condition(s)), the non-breaching party
shall have the option to terminate this Agreement with respect to such breaching
party at the close of business on such date without liability of any party to
any other party; provided, however, that if this Agreement is terminated
pursuant to this Section 8(k) and neither of the Investors is in breach of this
Agreement, the Company shall remain obligated to reimburse the Investors for
expenses up to the amount described in Section 4(f) above.

l.Placement Agent or Exchange Agent. The Company
acknowledges that it has not engaged a placement agent or exchange agent in
connection with the redemption and exchange of the Notes. The Company shall be
responsible for the payment of any placement agent's fees, exchange agent fees
or brokers' commissions relating to or arising out of the transactions
contemplated hereby. The Company shall pay, and hold each Investor harmless
against, any liability, loss or expense (including, without limitation,
attorneys' fees and out of pocket expenses) arising in connection with any such
claim.

m.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.

n.Remedies. Each Investor and each holder of the Common
Shares shall have all rights and remedies set forth in the Transaction Documents
and all rights and remedies which such holders have been granted at any time
under any other agreement or contract and all of the rights which such holders
have under any law. Any person having any rights under any provision of this
Agreement shall be entitled to enforce such rights specifically (without posting
a bond or other security), to recover damages by reason of any breach of any
provision of this Agreement and to exercise all other rights granted by law.

o.Payment Set Aside. To the extent that the Company makes
a payment or payments to any Investor hereunder or pursuant to the Registration
Rights Agreement or the Warrants or such Investor enforces or exercises its
rights hereunder or thereunder, and such payment or payments or the proceeds of
such enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged
by or are required to be refunded, repaid or otherwise restored to the Company,
a trustee, receiver or any other person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or
part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.


p.Mutual General Release.
i.In consideration of the releases set forth in Section 8(p)(ii),
effective as of the Closing, each Investor, severally and not jointly, on behalf
of itself and, to the extent permitted by law, its heirs, executors,
administrators, devisees, trustees, partners, directors, officers, shareholders,
employees, consultants, representatives, predecessors, principals, agents,
parents, associates, affiliates, subsidiaries, attorneys, accountants,
successors, successors-in-interest and assignees (collectively, the "Investor
Releasing Persons"), hereby waives and releases, to the fullest extent
permitted by law, but subject to Section 8(p)(iii) below, any and all claims,
rights and causes of action, whether known or unknown (collectively, the
"Investor Claims"), that any of the Investor Releasing Persons had,
currently has or as of the Closing may have against (i) the Company, (ii) any of
the Company's current or former parents, shareholders, affiliates, subsidiaries,
predecessors or assigns, or (iii) any of the Company's or such other persons' or
entities' current or former officers, directors, employees, agents, principals,
investors, signatories, advisors, consultants, spouses, heirs, estates,
executors, attorneys, auditors and associates and members of their immediate
families (collectively, the "Company Released Persons"), including,
without limitation, Investor Claims arising out of or relating to the Securities
Purchase Agreement and the First Registration Rights Agreement (collectively,
the "Released Documents") other than Investor Claims arising after the
Closing.

ii.In further consideration of the Investors entering into this
Agreement, effective as of the Closing, the Company on behalf of itself and, to
the extent permitted by law, its heirs, executors, administrators, devisees,
trustees, partners, directors, officers, shareholders, employees, consultants,
representatives, predecessors, principals, agents, parents, associates,
affiliates, subsidiaries, attorneys, accountants, successors, successors-in-
interest and assignees (collectively, the "Company Releasing Persons"),
hereby waives and releases, to the fullest extent permitted by law, but subject
to Section 8(p)(iii) below, any and all claims, rights and causes of action,
whether known or unknown (collectively, the "Company Claims"), that any
of the Company Releasing Persons had, currently has or as of the Closing may
have against (i) the Investors, (ii) any of the Investors' respective current or
former parents, shareholders, affiliates, subsidiaries, predecessors or assigns,
or (iii) any of the Investors' or such other persons' or entities' current or
former officers, directors, employees, agents, principals, investors,
signatories, advisors, consultants, spouses, heirs, estates, executors,
attorneys, auditors and associates and members of their immediate families
(collectively, the "Investor Released Persons"), including, without
limitation, any Company Claims arising out of or relating to the Released
Documents.

iii.The Company and each of the Investors acknowledge that the releases
set forth in Sections 8(p)(i) and 8(p)(ii) above do not affect any claim which
any Company Releasing Person or Investor Releasing Person may have under this
Agreement, or Section 9(m) or clause (c) of the first paragraph of Section 8 of
the Securities Purchase Agreement or Sections 5, 6 or 7 of the First
Registration Rights Agreement.

iv.It is the intention of each party that
this Section 8(p) shall be effective as a final accord and satisfaction and
release of each and every Investor Claim and Company Claim, except as otherwise
specifically provided in this Section 8(p). In furtherance of this intention,
each party acknowledges that it is familiar with Section 1542 of the California
Civil Code which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT NOW
KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE,
WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
DEBTOR.

Each party hereby waives and relinquishes every right or benefit
which it may have under Section 1542 or the California Civil Code to the extent
that it may lawfully waive such right or benefit pertaining to the subject
matter of this Agreement. Each party acknowledges that the foregoing waiver was
separately bargained for and is a key element of the Agreement of which this
release is a part.
