and the Other Agreements, as applicable, and the Indenture, will constitute
legal and binding obligations of the Company, be validly issued and free of
restrictions on transfer other than restrictions on transfer under this
Agreement, applicable state and federal securities laws and liens or
encumbrances created by or imposed by the Holders, and enforceable against the
Company in accordance with their terms, except that such enforcement may be
limited by (a) bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting or relating to enforcement of creditors’ rights
generally, and (b) general principles of equity. Assuming the accuracy of
the representations of each of the Holders in Section 2 of this Agreement

Other Agreements, the New Notes will be issued in compliance in all material
respects with all applicable federal and state securities laws. The Underlying
Common Stock has been duly reserved for issuance, and upon issuance in
accordance with the terms of the Certificate of Incorporation, will be validly
issued, fully paid and nonassessable and free of restrictions on transfer other
than liens or encumbrances created by or imposed by the Holders or the Other

Holders in Section 2 of each of the Other Agreements, the Underlying Common
Stock, when issued and delivered in accordance with the terms of the New Notes
and the Indenture, will be issued in compliance in all material respects with

Common Stock.  None of the Company, its subsidiaries, any of their
affiliates and any Persons acting on their behalf has, directly or indirectly,
made any offers or sales of any security or solicited any offers to buy any
security, under circumstances that would require registration of any of the New
Notes or the Underlying Common Stock under the Securities Act or cause this
offering of the New Notes and the Underlying Common Stock to be integrated with
prior offerings by the Company for purposes of any applicable stockholder
approval provisions, including under the rules and regulations of the NASDAQ
Capital Market.  None of the Company, its subsidiaries, their
affiliates and any Persons acting on their behalf will take any action or steps
referred to in the preceding sentence that would require registration of any of
the New Notes or the Underlying Common Stock under the Securities Act or cause
the offering of the New Notes or the Underlying Common Stock to be integrated
with other offerings for purposes of any applicable stockholder approval
provisions.  For purposes hereof, “Person” means an individual, a
limited liability company, a partnership, a joint venture, a corporation, a
trust, an unincorporated organization or a government or any department or
agency thereof or any other legal entity.  Without limiting the
foregoing, the issuance by the Company of the New Notes is, and the issuance of
the Underlying Common Stock upon conversion of the New Notes will be, exempt
from registration under the Securities Act and state securities laws pursuant to
the exemption from registration set forth in Section 3(a)(9) of the Securities
Act and similar exemptions under state law.

proceedings relating to the revocation or modification of any such certificate,
authorization or permit which would reasonably be expected to, singly or in the
aggregate, result in a Material Adverse Effect. The Company and its subsidiaries
are and have been in compliance with all applicable laws, statutes, ordinances,
rules, regulations, orders, judgments, decisions, decrees, standards, and
requirements relating to their respective businesses, except where any such
non-compliance would not reasonably be expected to have a Material Adverse
Effect.  Except as described in the SEC Documents, without limiting
the generality of the foregoing, the Company is not in violation of any of the
material rules, regulations or requirements of the NASDAQ Capital Market and has
no knowledge of any facts or circumstances that would reasonably lead to
delisting or suspension of the Common Stock by the NASDAQ Capital Market in the
foreseeable future.  Except as described in the SEC Documents, the
Company has not received any communication, written or oral, from the SEC or the
NASDAQ Capital Market regarding the suspension or delisting of the Common Stock
from the NASDAQ Capital Market.

     

    Section
3.8      No Material Adverse
Effect.  Since the respective dates as of which information is
given in the SEC Documents, there has not been any event, development or
occurrence having a Material Adverse Effect on the Company or its subsidiaries,
except as reflected or disclosed in a subsequent SEC Document.

     

    Section
3.9      Disclosure.  On
or before the first business day following the date of this Agreement, the
Company shall issue a press release and file a Form 8-K with the SEC disclosing
all material terms of the transactions contemplated hereby (and, in the case of
such Form 8-K, including the Transaction Documents as exhibits thereto) and any
other material nonpublic information delivered by the Company or its agents or
counsel to any of the Holders or any agent acting on its behalf.  Upon
the filing of such press release and Form 8-K, no Holder shall be in possession
of any information that constitutes or could reasonably be expected to
constitute material, nonpublic information provided to such Holder by the
Company or any agent acting on its behalf.  The Company shall not, and
shall cause each of its subsidiaries and its and each of their respective
officers, directors, employees and agents not to, provide any Holder with any
material, nonpublic information regarding the Company or any of its subsidiaries
from and after the filing of such Form 8-K with the SEC without the express
written consent of each of the Holders. The Company understands and confirms
that each of the Holders will rely on the foregoing representations in effecting
the transactions contemplated hereby.

    Section
3.10    Dilution.  The
Company hereby acknowledges that (a) either of the Holders or one or more of the
Other Holders may engage in hedging and/or trading activities at various times
during the period that the New Notes and the Underlying Common Stock are
outstanding, including during the periods that the value of the shares of
Underlying Common Stock deliverable with respect to Securities are being
determined and (b) such hedging and/or trading activities, if any, can reduce
the value of the existing stockholders’ equity interests in the Company both at
and after the times the hedging and/or trading activities are being
conducted.  The Company acknowledges that such aforementioned hedging
and/or trading activities do not constitute a breach of this Agreement, the New
Notes or any of the documents executed in connection
herewith.  Notwithstanding the forgoing, the Company assumes that all
such activity by the Holders and each of the Other Holders shall be in
compliance with all applicable federal and state securities laws and disclaims
any liability for actions by the Holders or any of the Other Holders that fail
to comply with all applicable laws.

     

    Section
3.11    Outstanding
Obligations.  As of the date hereof, there are $10,013,000 in
aggregate principal amount of Outstanding Notes, including the Holder
Outstanding Notes.  Upon the consummation of the transactions
contemplated hereby and by the Other Agreements, there will be no Outstanding
Notes outstanding.  Immediately following the Closing, $10,013,000 in
aggregate principal amount of New Notes, including the Holder New Notes, will be
outstanding.

     

    Section
3.12    Legend.  The
Company acknowledges and agrees that, based on each of the Holders’
representations made in Section 2 of this Agreement, as of the Closing Date none
of the Holder New Notes, nor any shares of Underlying Common Stock issuable upon
conversion of the Holder New Notes, shall bear any legend regarding registration
under the Securities Act or restrictions on transfer.

     

    Section
3.13    Rule
144.  Assuming neither of the Holders becomes an affiliate of
the Company, the Company shall not, directly or indirectly, dispute or otherwise
interfere with any claim by the Holders that the holding period of any Holder
New Notes and Underlying Common Stock issued upon conversion of any Holder New
Notes (including any Underlying Common Stock issued to any Holders pursuant to
an Installment Conversion (as defined in the Indenture)) for purposes of Rule
144 relates back (i.e., tacks) to the holding period for the Holder Outstanding
Notes.  The Company agrees and acknowledges that, assuming as provided
in this Section 3.13, under Rule 144, as currently in effect, such tacking is
permitted.

     

    Section
3.14    Additional
Securities-Related Covenants.    The Company shall
use all reasonable efforts to cause the Indenture to be qualified under the
Trust Indenture Act of 1939, as amended, and the rules and regulations
thereunder (the “TIA”), in a timely
manner and, in connection therewith, cooperate with the Trustee and the Holders
of the New Notes or the Underlying Common Stock to effect such changes to the
Indenture, if any, as may be required for such Indenture to be so qualified in
accordance with the terms of the TIA, and execute, and use all reasonable
efforts to cause the Trustee to execute, all customary documents as may be
required to effect such changes, and all other forms and documents (including
Form T-1) required to be filed with the SEC to enable the Indenture to be so
qualified.  The Company shall (a) list the Underlying Common Stock on
any securities exchange on which the Common Stock is then listed, (b) use its
reasonable efforts to maintain the listing of the Common Stock on the NASDAQ
Capital Market or another national securities exchange (including by using
reasonable efforts to comply with the rules and regulations thereof), and (c)
use its reasonable efforts to file with the SEC in a timely manner all annual
reports on Form 10-K and quarterly reports on Form 10-Q required of the Company
under the Exchange Act so long as the Company remains subject to such
requirements.

Notes or Outstanding Notes Indenture.  The Company has not
breached or violated any of the provisions of, nor is there any continuing
Default or Event of Default (each as defined in the Outstanding Notes Indenture)
under, any of the Outstanding Notes or the Outstanding Notes
Indenture.

     

    Section
3.16    Acknowledgments.  The
Company hereby irrevocably and unconditionally acknowledges, affirms and
covenants to each of the Holders that:

     

    (a)     neither
of the Holders is in default under such Holder’s Holder Outstanding Notes, the
Outstanding Notes Indenture or any of the agreements, arrangements or
understandings entered into or agreed upon by either of the Holders in
connection with, or otherwise relating to, the acquisition of the Holder
Outstanding Notes by the Holders (the “Outstanding Notes
Documents”), as applicable, and has not otherwise breached any
obligations to the Company or any of its subsidiaries.

     

    (b)    there
are no offsets, counterclaims or defenses to the obligations, liabilities and
indebtedness of every nature of the Company owed under or in respect of either
of the Holder Outstanding Notes or the Holder New Notes (the “Obligations”),
including the liabilities and obligations of the Company under the Holder
Outstanding Notes or the Holder New Notes or to the rights,
remedies or powers of either of the Holders in respect of any of the
Obligations, any of the Holder Outstanding Notes Documents, the Outstanding
Notes Indenture or any of the  Transaction Documents, as applicable,
and the Company agrees not to, and to cause each of its subsidiaries not to,
interpose (and each does hereby waive and release) any such defense, set-off or
counterclaim in any action brought by either of the Holders with respect
thereto.

receipt requested or sent by reputable overnight courier service (charges

Agreement.  This Agreement, the Holder New Notes, the Indenture
and the other documents and agreements executed in connection with the
transactions contemplated hereby embody the entire agreement and understanding
of the parties hereto with respect to the subject matter hereof and supersede
all prior and contemporaneous oral or written agreements, representations,

    Section
4.3      Assignment; Binding
Agreement.  This Agreement and the various rights and
obligations arising hereunder shall inure to the benefit of and be binding upon
the parties hereto and their successors and assigns.

     

    Section
4.4      Counterparts.  This
Agreement may be executed in multiple counterparts, and on separate
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute one and the same instrument. Any counterpart or other
signature hereupon delivered by facsimile or other electronic transmission shall
be deemed for all purposes as constituting good and valid execution and delivery
of this Agreement by such party.

     

    Section
4.5      Remedies
Cumulative.  All rights and remedies of the parties under this
Agreement are cumulative and without prejudice to any other rights or remedies
available under this Agreement or at law or in equity (including a decree of
specific performance and/or other injunctive relief), and no remedy contained
herein shall be deemed a waiver of compliance with the provisions giving rise to
such remedy, and nothing herein shall limit any Holder’s right to pursue actual
damages for any failure by the Company to comply with the terms of this
Agreement.  The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the Holders and that the
remedy at law for any such breach may be inadequate.  The Company
therefore agrees that, in the event of any such breach or threatened breach,
each Holder shall be entitled, in addition to all other available remedies, to
an injunction restraining any breach, without the necessity of showing economic
loss and without any bond or other security being required.

     

    Section
4.6      Governing
Law.  This Agreement shall in all respects be construed in
accordance with and governed by the substantive laws of the State of New York,
without reference to its choice of law rules.  Each party hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in The City of New York, Borough of Manhattan, 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.

     

    Section
4.7      No Third Party Beneficiaries
or Other Rights.  Except as provided in Section 4.16, nothing
herein shall grant to or create in any person not a party hereto, or any such
person’s dependents or heirs, any right to any benefits hereunder, and no such
party shall be entitled to sue any party to this Agreement with respect
thereto.

     

    Section
4.8      Waiver;
Consent.  This Agreement may not be changed, amended,
terminated, augmented, rescinded or discharged (other than in accordance with
its terms), in whole or in part, except by a writing executed by the parties
hereto. No waiver of any of the provisions or conditions of this Agreement or
any of the rights of a party hereto shall be effective or binding unless such
waiver shall be in writing and signed by the party claimed to have given or
consented thereto. Except to the extent otherwise agreed in writing, no waiver
of any term, condition or other provision of this Agreement, or any breach
thereof shall be deemed to be a waiver of any other term, condition or provision
or any breach thereof, or any subsequent breach of the same term, condition or
provision, nor shall any forbearance to seek a remedy for any noncompliance or
breach be deemed to be a waiver of a party’s rights and remedies with respect to
such noncompliance or breach.

The singular shall include the plural, and vice versa, unless the context
otherwise requires. The masculine shall include the feminine and neuter, and

Broker.  Each party represents and warrants that it has not
engaged any third party as broker or finder or incurred or become obligated to
pay any broker’s commission or finder’s fee in connection with the transactions
contemplated by this Agreement other than such fees and expenses for which it
shall be solely responsible.

     

    Section
4.11    Further
Assurances.  Each of the Holders and the Company each hereby
agree to execute and deliver, or cause to be executed and delivered, such other
documents, instruments and agreements, and take such other actions, as either
party may reasonably request in connection with the transactions contemplated by
this Agreement.

     

    Section

reasonable attorneys’ fees, against delivery to the Company of invoices or other
appropriate documentation in reasonable detail.  The Company shall pay
its own fees, costs and expenses incurred in connection with the drafting,
negotiation, preparation, execution and performance of this Agreement, including
attorneys’ fees.

     

    Section
4.13    Headings.  The
headings in this Agreement are for convenience of reference only and shall not
limit or otherwise affect the meaning hereof.

     

    Section
4.14    Severability.  If
any one or more of the provisions contained herein, or the application thereof
in any circumstance, is held invalid, illegal or unenforceable, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions contained herein shall not be affected or impaired
thereby.

     

    Section
4.15    Reasonable Best
Efforts.  Each party shall use its reasonable best efforts to
timely satisfy each of the conditions to be satisfied by it as provided in
Section 1.3 of this Agreement.

    Section
4.16    Indemnification.  In
consideration of each Holder’s execution and delivery of this Agreement and
acquiring such Holder’s Holder New Notes in exchange for such Holder’s Holder
Outstanding Notes hereunder and in addition to all of the Company’s other
obligations under this Agreement and the other Transaction Documents, the
Company shall defend, protect, indemnify and hold harmless the Holders and each
of the Holders’ respective stockholders, partners, members, managers, officers,
directors, employees and direct or indirect investors and any of the foregoing
Persons’ agents or other representatives (including those retained in connection
with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”, who are
the third party beneficiaries of this Section 4.16), as incurred, from and
against any and all actions, causes of action, suits, claims, losses, costs,
penalties, fees, liabilities and damages, and expenses 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 this Agreement or any of the other Transaction
Documents, or (b) any breach of any covenant, agreement or obligation of the
Company contained in this Agreement or any of the other Transaction
Documents.  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.

     

    Section
4.17    Independent Nature of
Obligations and Rights.  The obligations of each of the Holders
and the Other Holders under any Transaction Documents are several and not joint
with the obligations of any other such Person, and no Holder shall not be
responsible in any way for the performance of the obligations of the other
Holder or any Other Holder under any of the Transaction
Documents.  Nothing contained herein or in any other Transaction
Document, and no action taken by any of the Holders or any of the Other Holders
pursuant hereto or thereto, shall be deemed to constitute any Holder and any of
the Other Holders as a partnership, an association, a joint venture or any other
kind of entity, or create a presumption that they are in any way acting in
concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents, and the Company acknowledges that
they are not acting in concert or as a group, and the Company will not assert
any such claim with respect to such obligations or the transactions contemplated
by the Transaction Documents.  Each of the Holders and the Other
Holders shall be entitled to independently protect and enforce its rights,
including the rights arising out of this Agreement or out of any other
Transaction Document, and it shall not be necessary for any other Person to be
joined as an additional party in any proceeding for such purpose.
