conduct their respective businesses and are in good standing as a           foreign
corporation or other entity in each jurisdiction in which the nature of           the
business conducted or property owned by it makes such qualification           necessary,
except where the failure to be so qualified or in good standing, as           the case
may be, could not, individually or in the aggregate, have or reasonably           be
expected to result in a Material Adverse Effect.

Company or a Subsidiary is bound or affected; except in           the case of each of

applicable           bankruptcy, insolvency, reorganization, moratorium, liquidation or

nonassessable           and were issued in full compliance with applicable state and
federal securities           law and any rights of third parties. The issue and sale of

Company securities to adjust the           exercise, conversion, exchange or reset price

          Reports, when filed, contained any untrue statement of a material fact or

          they were made, not misleading. The financial statements of the Company
included           in the SEC Reports comply in all material respects with applicable
accounting           requirements and the rules and regulations of the Commission with
respect           thereto as in effect at the time of filing. Such financial statements

disclosed in the SEC Reports, could, if there were an           unfavorable decision,
individually or in the aggregate, have or reasonably be           expected to result in a
Material Adverse Effect; and to the Companys           Knowledge, no such Action is

          limitation all foreign, federal, state and local laws relating to taxes,
          environmental protection, occupational health and safety, product quality and
          safety and employment and labor matters, except in each case as could not,
          individually or in the aggregate, have or reasonably be expected to result in a
          Material Adverse Effect.

Permits. The Company and the Subsidiaries possess all           certificates,
authorizations and permits issued by the appropriate federal,           state, local or
foreign regulatory authorities necessary to conduct their           respective businesses
as described in the SEC Reports, except where the failure           to possess such
permits could not, individually or in the aggregate, have or           reasonably be
expected to result in a Material Adverse Effect, and neither the           Company nor
any Subsidiary has received any notice of proceedings relating to           the
revocation or modification of any such permits.

(n)    Title
to Assets. The Company and the Subsidiaries have good and           marketable title
in fee simple to all real property owned by them that is           material to their
respective businesses and good and marketable title in all           personal property
owned by them that is material to their respective businesses,           in each case
free and clear of all Liens, except for Liens as do not materially           affect the
value of such property and do not materially interfere with the use           made and
proposed to be made of such property by the Company and the           Subsidiaries. Any
real property and facilities held under lease by the Company           and the
Subsidiaries are held by them under valid, subsisting and enforceable           leases of
which the Company and the Subsidiaries are in compliance, except as           could not,
individually or in the aggregate, have or reasonably be expected to           result in a
Material Adverse Effect.

(o)    Intellectual
Property.

(i)              Except
as set forth in Schedule 3.1(o), the Company has not transferred           any
rights or interest in, or granted any exclusive license with respect to, any           of
its Intellectual Property, to any third party.

(ii)              All
Intellectual Property of the Company and its Subsidiaries is currently in
          compliance with all legal requirements (including timely filings, proofs and
          payments of fees) and is valid and enforceable. No Intellectual Property of the
          Company or its Subsidiaries which is necessary for the conduct of the
          Companys and each of its Subsidiaries respective businesses as
          currently conducted or as currently proposed to be conducted has been or is now
          involved in any cancellation, dispute or litigation, and, to the Companys
          Knowledge, no such action is threatened. No patent of the Company or its
          Subsidiaries has been or is now involved in any interference, reissue,
          re-examination or opposition proceeding.

(iii)              All
of the licenses and sublicenses and consent, royalty or other agreements
          concerning Intellectual Property (including those entered into in connection
          with a Collaborative Relationship described in the SEC Reports) used in the
          conduct of the Companys and each of its Subsidiaries respective
businesses           as currently conducted or as currently proposed to be conducted to
which the           Company or any subsidiary is a party or by which any of its assets
are bound           (other than generally commercially available, non-custom,
off-the-shelf software           application programs having a retail acquisition price
of less than $10,000 per           license) (collectively, License Agreements)
are valid and           binding obligations of the Company or its Subsidiaries which are
parties thereto           and, to the Companys Knowledge, of the other parties
thereto, enforceable           in accordance with their terms, except to the extent that
enforcement thereof           may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent           conveyance or other similar laws affecting the
enforcement of creditors          rights generally, and, neither the Company nor
any other party thereto is in           material violation or breach of any such License
Agreement, and no action or           failure to act by the Company or any Subsidiary
constitutes (with or without due           notice or lapse of time or both) a material
default by the Company thereunder.

---

(iv)              The
Company and its Subsidiaries own or have the valid right to use all of the
          Intellectual Property that is necessary for the conduct of the Companys
          and each of its Subsidiaries respective businesses as currently conducted
          or as currently proposed to be conducted and for the ownership, maintenance and
          operation of the Companys and its Subsidiaries properties and
          assets, free and clear of all liens, encumbrances, adverse claims or
obligations           to license all such owned Intellectual Property and Confidential
Information,           other than licenses entered into in the ordinary course of the
Companys           and its Subsidiaries businesses. The Company and its
Subsidiaries have a           valid and enforceable right to use all third party
Intellectual Property and           Confidential Information used or held for use in the
respective businesses of           the Company and its Subsidiaries.

(v)              The
conduct of the Companys and its Subsidiaries businesses as
          currently conducted does not infringe or otherwise impair or conflict with
          (collectively, Infringe) any Intellectual Property rights of any
          third party or any confidentiality obligation owed to a third party, and, to
the           Companys Knowledge, the Intellectual Property and Confidential
Information           of the Company and its Subsidiaries which are necessary for the
conduct of           Companys and each of its Subsidiaries respective
businesses as           currently conducted or as currently proposed to be conducted are
not being           Infringed by any third party. There is no litigation or order pending
or           outstanding or, to the Companys Knowledge, threatened or imminent,
that           seeks to limit or challenge or that concerns the ownership, use, validity
or           enforceability of any Intellectual Property or Confidential Information of
the           Company and its Subsidiaries or the Companys and its Subsidiaries          use
of any Intellectual Property or Confidential Information owned by a third
          party, and, to the Companys Knowledge, there is no valid basis for the
          same.

(vi)              The
consummation of the transactions contemplated hereby and by the other
          Transaction Documents will not result in the alteration, loss, impairment of or
          restriction on the Companys or any of its Subsidiaries ownership or
          right to use any of the Intellectual Property or Confidential Information which
          is necessary for the conduct of the Companys and each of its
          Subsidiaries respective businesses as currently conducted or as currently
          proposed to be conducted.

---

(vii)              The
Company and its Subsidiaries have taken reasonable steps to protect the           Companys
and its Subsidiaries rights in their Intellectual Property           and
Confidential Information. Each employee, consultant and contractor who has           had
access to Confidential Information which is necessary for the conduct of           Companys
and each of its Subsidiaries respective businesses as           currently conducted
or as currently proposed to be conducted has executed an           agreement to maintain
the confidentiality of such Confidential Information and           has executed
appropriate agreements that are substantially consistent with the           Companys
standard forms thereof. Except under confidentiality obligations,           there has
been no material disclosure of any of the Companys or its           Subsidiaries Confidential
Information to any third party.

(p)    Transactions
With Affiliates and Employees. Except as set forth in the           SEC Reports, none
of the officers or directors of the Company and, to the           Companys
Knowledge, none of the employees of the Company is presently a           party to any
transaction with the Company or any Subsidiary (other than for           services as
employees, officers and directors), including any contract,           agreement or other
arrangement providing for the furnishing of services to or           by, providing for
rental of real or personal property to or from, or otherwise           requiring payments
to or from any officer, director or such employee or, to the           Companys
Knowledge, any entity in which any officer, director, or any such           employee has
a substantial interest or is an officer, director, trustee or           partner.

(q)    Certain
Fees. No brokerage or finders fees or commissions are or           will be
payable by the Company to any broker, financial advisor or consultant,           finder,
placement agent, investment banker, bank or other Person with respect to           the
transactions contemplated by this Agreement. The Lenders shall have no
          obligation with respect to any fees or with respect to any claims (other than
          such fees or commissions owed by a Lender pursuant to written agreements
          executed by such Lender which fees or commissions shall be the sole
          responsibility of such Lender) made by or on behalf of other Persons for fees
of           a type contemplated in this Section that may be due in connection with the
          transactions contemplated by this Agreement.

(r)    Investment
Company. The Company is not, and is not an Affiliate of, and           immediately
following the Closing will not have become, an investment           company within
the meaning of the Investment Company Act of 1940, as           amended.

(s)    Certain
Registration Matters. Assuming the accuracy of the Lenders          representations
and warranties set forth in Section 3.2(b)-(e), no           registration under
the Securities Act is required for the issuance and sale of           the Notes and
Conversion Shares by the Company to the Lenders under the           Transaction
Documents. The Company is eligible to register the resale of its           Common Stock
for resale by the Lenders under Form SB-2 promulgated under the           Securities Act.
Except as specified in Schedule 3.1(s), the Company has           not granted or
agreed to grant to any Person any rights (including           piggy-back registration
rights) to have any securities of the           Company registered with the Commission or
any other governmental authority that           have not been satisfied.

---

(t)    Listing
and Maintenance Requirements. Except as specified in the SEC           Reports or
Schedule 3.1(t), the Company has not, in the two years preceding the           date
hereof, received notice from any Trading Market to the effect that the           Company
is not in compliance with the listing or maintenance requirements           thereof. The
Company is, and has no reason to believe that it will not in the           foreseeable
future continue to be, in compliance with the listing and           maintenance
requirements for continued listing of the Common Stock on the           Trading Market on
which the Common Stock is currently listed or quoted. The           issuance and sale of
the Notes under the Transaction Documents does not           contravene the rules and
regulations of the Trading Market on which the Common           Stock is currently listed
or quoted, and no approval of the shareholders of the           Company thereunder is
required for the Company to issue and deliver to the           Lenders the Notes
contemplated by Transaction Documents.

(u)    Application
of Takeover Protections. The Company has 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 Companys           Certificate
of Incorporation (or similar charter documents) or the laws of its           state of
incorporation that is or could become applicable to the Lenders as a           result of
the Lenders and the Company fulfilling their obligations or exercising           their
rights under the Transaction Documents, including without limitation the           Companys
issuance of the Notes and the Conversion Shares and the           Lenders ownership
of the Notes or Conversion Shares.

(v)    No
Additional Agreements. The Company does not have any agreement or
          understanding with any Lender with respect to the transactions contemplated by
          the Transaction Documents other than as specified in the Transaction Documents.

(w)    No
Directed Selling Efforts or General Solicitation. Neither the Company           nor
any Person acting on its behalf has conducted any general solicitation or
          general advertising (as those terms are used in Regulation D) in connection
with           the offer or sale of any of the Securities.

(x)    No
Integrated Offering. Neither the Company nor any of its Affiliates,           nor any
Person acting on its or their behalf has, directly or indirectly, made           any
offers or sales of any Company security or solicited any offers to buy any
          security, under circumstances that would adversely affect reliance by the
          Company on Section 4(2) for the exemption from registration for the
transactions           contemplated hereby or would require registration of the Notes
under the           Securities Act.

(y)    Questionable
Payments.Neither the Company           nor any of its
Subsidiaries nor, to the Companys Knowledge, any of their           respective
current or former stockholders, directors, officers, employees,           agents or other
Persons acting on behalf of the Company or any Subsidiary, has           on behalf of the
Company or any Subsidiary or in connection with their           respective businesses:
(i) used any corporate funds for unlawful contributions,           gifts, entertainment
or other unlawful expenses relating to political activity;           (ii) made any direct
or indirect unlawful payments to any governmental officials           or employees from
corporate funds; (iii) established or maintained any unlawful           or unrecorded
fund of corporate monies or other assets; (iv) made any false or           fictitious
entries on the books and records of the Company or any Subsidiary; or           (v) made
any unlawful bribe, rebate, payoff, influence payment, kickback or           other
unlawful payment of any nature.

---

(z)    Internal
Controls. The Company is in material compliance with the           provisions of the
Sarbanes-Oxley Act of 2002 currently applicable to the           Company. The Company and
the Subsidiaries maintain a system of internal           accounting controls sufficient
to provide reasonable assurance that (i)           transactions are executed in
accordance with managements general or           specific authorizations, (ii)
transactions are recorded as necessary to permit           preparation of financial
statements in conformity with generally accepted           accounting principles and to
maintain asset accountability, (iii) access to           assets is permitted only in
accordance with managements general or           specific authorization, and (iv)
the recorded accountability for assets is           compared with the existing assets at
reasonable intervals and appropriate action           is taken with respect to any
differences. The Company has established disclosure           controls and procedures (as
defined in Exchange Act Rules 13a-14 and 15d-14) for           the Company and designed
such disclosure controls and procedures to ensure that           material information
relating to the Company, including the Subsidiaries, is           made known to the
certifying officers by others within those entities,           particularly during the
period in which the Companys most recently filed           periodic report under
the Exchange Act, as the case may be, is being prepared.           The Companys
certifying officers have evaluated the effectiveness of the           Companys
controls and procedures as of a date within 90 days prior to the           filing date of
the most recently filed periodic report under the Exchange Act           (such date, the
Evaluation Date). The Company presented in           its most recently
filed periodic report under the Exchange Act the conclusions           of the certifying
officers about the effectiveness of the disclosure controls           and procedures
based on their evaluations as of the Evaluation Date. Since the           Evaluation
Date, there have been no significant changes in the Companys           internal
controls (as such term is defined in Item 308(c) of Regulation S-K) or,           to the
Companys Knowledge, in other factors that could 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           Exchange Act.

(aa)    Environmental
Matters. To the Companys Knowledge, neither the           Company nor any
Subsidiary is in violation of any statute, rule, regulation,           decision or order
of any governmental agency or body or any court, domestic or           foreign, relating
to the use, disposal or release of hazardous or toxic           substances or relating to
the protection or restoration of the environment or           human exposure to hazardous
or toxic substances (collectively,           Environmental Laws).
Neither the Company nor any Subsidiary           owns or operates any real property
contaminated with any substance that is           subject to any Environmental Laws, is
liable for any off-site disposal or           contamination pursuant to any Environmental
Laws, or is subject to any claim           relating to any Environmental Laws, which
violation, contamination, liability or           claim has had or could reasonably be
expected to have a Material Adverse Effect,           individually or in the aggregate;
and there is no pending or, to the           Companys Knowledge, threatened
investigation that might lead to such a           claim.

---

(bb)    Tax
Matters. The Company and each Subsidiary has filed for an extension           of the
time to file its 2002 income tax returns and has not filed its 2003           income tax
returns. The charges, accruals and reserves on the books of the           Company in
respect of taxes for all fiscal periods are adequate in all material           respects,
and there are no material unpaid assessments against the Company or           any
Subsidiary nor, to the Companys Knowledge, any basis for the           assessment
of any additional taxes, penalties or interest for any fiscal period           or audits
by any federal, state or local taxing authority except for any           assessment which
is not material to the Company and its Subsidiaries, taken as a           whole. All
taxes and other assessments and levies that the Company or any           Subsidiary is
required to withhold or to collect for payment have been duly           withheld and
collected and paid to the proper governmental entity or third party           when due.
There are no tax liens or claims pending or, to the Companys           Knowledge,
threatened against the Company or any Subsidiary or any of their           respective
assets or property. There are no outstanding tax sharing agreements           or other
such arrangements between the Company and any Subsidiary or other           corporation
or entity.

(cc)    Insurance
Coverage. The Company and each Subsidiary maintains in full           force and
effect insurance coverage that is customary for comparably situated           companies
for the business being conducted and properties owned or leased by the           Company
and each Subsidiary, and the Company reasonably believes such insurance
          coverage to be adequate against all liabilities, claims and risks against which
          it is customary for comparably situated companies to insure.

(dd)    Disclosures.
The Company and each Person acting on its behalf has           identified for each Lender
any information that constitutes or might constitute           material, non-public
information that has been disclosed to such Lender in           connection with this
transaction and that such information must remain           confidential until such time
as the Company publicly discloses it. The written           materials delivered to the
Lenders in connection with the transactions           contemplated by the Transaction
Documents do not contain any untrue statement of           a material fact or omit to
state a material fact necessary in order to make the           statements contained
therein, in light of the circumstances under which they           were made, not
misleading.

(ee)    Solvency.
On and immediately after the Closing Date, the Company (after           giving effect to
the issuance of the Notes) will be Solvent. As used in this           paragraph, the term
Solvent means, with respect to a           particular date, that on
such date (i) the present fair market value (or present           fair saleable value) of
the assets of the Company is not less than the total           amount required to pay the
probable liabilities of the Company on its total           existing debts and liabilities
(including contingent liabilities) as they become           absolute and matured, (ii)
the Company is able to realize upon its assets and           pay its debts and other
liabilities, contingent obligations and commitments as           they mature and become
due in the normal course of business, and (iii) assuming           the sale of the Notes
as contemplated by this Agreement, the Company is not           incurring debts or
liabilities beyond its ability to pay as such debts and           liabilities mature. In
computing the amount of such contingent liabilities at           any time, it is intended
that such liabilities will be computed at the amount           that, in the light of all
the facts and circumstances existing at such time,           represents the amount that
can reasonably be expected to become an actual or           matured liability.

3.2
    Representations and Warranties of the Lenders. Each Lender hereby, for itself and
for no other Lender, represents and warrants to the Company as follows:

(a)    Organization;
Authority. Such Lender is an entity duly organized, validly           existing and in
good standing under the laws of the jurisdiction of its           organization with the
requisite corporate or partnership power and authority to           enter into and to
consummate the transactions contemplated by the applicable           Transaction
Documents and otherwise to carry out its obligations thereunder. The           execution,
delivery and performance by such Lender of the transactions           contemplated by
this Agreement has been duly authorized by all necessary           corporate or, if such
Lender is not a corporation, such partnership, limited           liability company or
other applicable like action, on the part of such Lender.           Each of this
Agreement and the Registration Rights Agreement has been duly           executed by such
Lender, and when delivered by such Lender in accordance with           terms hereof, will
constitute the valid and legally binding obligation of such           Lender, enforceable
against it in accordance with its terms, except as such           enforceability may be
limited by applicable bankruptcy, insolvency,           reorganization, moratorium,
liquidation or similar laws relating to, or           affecting generally the enforcement
of, creditors rights and remedies or           by other equitable principles of
general application, including, without           limitation, limitations on rights to
indemnity or rights to a jury trial.

(b)    Investment
Intent. Such Lender is acquiring the Notes and Conversion           Shares as
principal for its own account for investment purposes only and not           with a view
to or for distributing or reselling such securities or any part           thereof,
without prejudice, however, to such Lenders right at all times to           sell or
otherwise dispose of all or any part of such securities in compliance           with
applicable federal and state securities laws. Subject to the immediately
          preceding sentence, nothing contained herein shall be deemed a representation
or           warranty by such Lender to hold the Notes or Conversion Shares for any
period of           time. Such Lender is acquiring the Notes and Conversion Shares
hereunder in the           ordinary course of its business. Such Lender does not have any
agreement or           understanding, directly or indirectly, with any Person to
distribute any of the           Notes or Conversion Shares.

(c)    Accredited
Investor Status. At the time such Lender was offered the           Notes, it was, and
at the date hereof it is, and on each date on which it           converts the Notes into
Common Stock it will be, an accredited           investor as defined in Rule
501(a) under the Securities Act. Such Lender           is not a registered broker-dealer
under Section 15 of the Exchange Act.

(d)    General
Solicitation. Such Lender is not purchasing the Notes as a result           of any
advertisement, article, notice or other communication regarding the Notes
          published in any newspaper, magazine or similar media or broadcast over
          television or radio or presented at any seminar or any other general
          solicitation or general advertisement.

---

(e)    Access
to Information. Such Lender acknowledges that it has reviewed the
          disclosure materials and the Private Placement Memorandum of the Company, dated
          May 6, 2004 (the PPM) delivered in connection with the
          Securities Purchase Agreement as well as the Disclosure Materials delivered in
          connection with this Agreement, and has been afforded (i) the opportunity to
ask           such questions as it has deemed necessary of, and to receive answers from,
          representatives of the Company concerning the terms and conditions of the
          offering of the Notes and the merits and risks of investing in the Notes and
          Conversion Shares; (ii) access to information about the Company and the
          Subsidiaries and their respective financial condition, results of operations,
          business, properties, management and prospects sufficient to enable it to
          evaluate its investment; and (iii) the opportunity to obtain such additional
          information that the Company possesses or can acquire without unreasonable
          effort or expense that is necessary to make an informed investment decision
with           respect to the investment. Neither such inquiries nor any other
investigation           conducted by or on behalf of such Lender or its representatives
or counsel shall           modify, amend or affect such Lenders right to rely on
the truth, accuracy           and completeness of the Disclosure Materials, the PPM and
the Companys           representations and warranties contained in the Transaction
Documents. Such           Lender acknowledges that it was advised prior to the execution
of the Securities           Purchase Agreement that Duane J. Roth, the Companys
Chief Executive           Officer, is the brother of Byron C. Roth of Roth Capital
Partners, LLC, the           placement agent who assisted the Company in connection with
the Securities           Purchase Agreement, and that Theodore D. Roth, a director of the
Company, is an           employee of Roth Capital Partners, LLC.

(f)    Certain
Trading Activities. Other than in connection with the Securities           Purchase
Agreement, such Lender has not directly or indirectly, nor has any           Person
acting on behalf of or pursuant to any understanding with such Lender,           engaged
in any transactions in the securities of the Company (including, without
          limitation, any Short Sales involving the Companys securities) since the
          earlier to occur of (1) the time that such Lender was contacted by the Company
          or any other Person regarding an investment in the Company and (2) the
          twenty-fifth (25th) day prior to the date of this Agreement. Except
          as expressly provided herein in connection with the Closing hereunder, such
          Lender covenants that neither it nor any Person acting on its behalf or
pursuant           to any understanding with it will engage in any transactions in the
securities           of the Company (including Short Sales) prior to the time that the
transactions           contemplated by this Agreement are publicly disclosed.

(g)    Independent
Investment Decision. Such Lender has independently evaluated           the merits of
its decision to purchase Notes pursuant to the Transaction           Documents, and such
Lender confirms that it has not relied on the advice of any           other Lenders
business and/or legal counsel in making such decision. Such           Lender has not
relied on the business or legal advice of Roth Capital Partners,           LLC or any of
its agents, counsel or Affiliates in making its investment           decision hereunder,
and confirms that none of such Persons has made any           representations or
warranties to such Lender in connection with the transactions           contemplated by
the Transaction Documents.

The Company acknowledges and agrees
that no Lender has made or makes any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in this
Section 3.2.

          enable the Company to undertake clinical trials of Oxygent, or (iii) to
          undertake any combination of the foregoing such that such third party is
          obligated to make expenditures and/or undertake activities, in each case that

(i)              Upon
the mutual written consent of the Company and the Lenders;

(ii)              By
the Company if any of the conditions set forth in Section 5.2 shall           have
become incapable of fulfillment, and shall not have been waived by the           Company;
or

(iii)              By
any Lender (with respect to itself only) if any of the conditions set forth           in

provided, however,
that, except in the case of clause (i) above, the party seeking to terminate its

representations, warranties, covenants or agreements contained in this Agreement or the
other Transaction Documents if such breach has resulted in the circumstances giving rise

(b)              In
the event of termination by the Company or any Lender of its obligations to
          effect the Closing pursuant to this Section 5.3, written notice thereof

          have the right to terminate the obligations of the Lenders to effect the

          any breach by such party of the terms and provisions of this Agreement or the
          other Transaction Documents or to impair the right of any party to compel
          specific performance by any other party of its obligations under this Agreement

ARTICLE VI.  SURVIVAL
AND INDEMNIFICATION.

6.1
    Survival. The representations, warranties, covenants and agreements contained in
this Agreement shall survive the Closing of the transactions contemplated by this
Agreement.

---

6.2
    Indemnification. The Company agrees to indemnify and hold harmless each Lender 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 no Indemnified Person shall
be entitled to bring a claim or claims for indemnification hereunder unless and until the
aggregate amount of such claim or claims equals or exceeds $50,000; provided, further,
however that the provisions of this Article VI shall not apply to any Loss based on an
alleged breach of fiduciary duty by the Board of Directors of the Company or any other
legal theory alleging a Loss due to the Rescission and Settlement Agreement.

6.3
    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 6.2, 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 (A) representation of
both parties by the same counsel would be inappropriate due to actual or potential
differing interests between them, or (B) one or more defenses is/are available to such
Indemnified Person that is/are not available to the Company. The Company shall not be
liable for any settlement of any proceeding effected without its written consent, which
consent shall not be unreasonably withheld, delayed or conditioned, 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.

ARTICLE VII.
MISCELLANEOUS

    Fees and Expenses. The payment of fees and expenses incurred in connection with

connection with this Agreement or the other Transaction Documents, the party or parties
which do not prevail in such proceedings shall severally, but not jointly, pay their pro

7.4
    Amendments; Waivers; No Additional Consideration. Except as expressly set forth
herein, no provision of this Agreement may be waived or amended except in a written
instrument signed by the Company and a majority of the members of the Lender Committee
except that any amendment or waiver affecting the principal amount, maturity date,
interest rate, designated currency, waiver of payment defaults, rights of the Holder to
institute suit for the enforcement of any payment, consent to the assignment or transfer
of the Companys rights or obligations under the Note (other than as permitted under
Section 4.12 herein) or the amendment and waiver provisions hereof shall require the
consent of each Holder as affected. No waiver of any default with respect to any
provision, condition or requirement of this Agreement shall be deemed to be a continuing
waiver in the future or a waiver of any subsequent default or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of either
party to exercise any right hereunder in any manner impair the exercise of any such
right. No consideration shall be offered or paid to any Lender to amend or consent to a
waiver or modification of any provision of any Transaction Document unless the same
consideration is also offered to all Lenders who then hold Notes.

7.5
    Construction. The headings herein are for convenience only, do not constitute a
part of this Agreement and shall not be deemed to limit or affect any of the provisions
hereof. 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. This Agreement shall be construed as if drafted jointly by the
parties, and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of the authorship of any provisions of this Agreement or any of the
Transaction Documents.

7.6
    Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the parties and their successors and permitted assigns. Any Lender may assign
any or all of its rights under this Agreement to any Person to whom such Lender assigns
or transfers any Notes, provided such transferee agrees in writing to be bound, with
respect to the transferred Notes, by the provisions hereof that apply to the Lenders.

7.7
    No Third-Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective successors and permitted assigns and is not for the
benefit of, nor may any provision hereof be enforced by any third party.

7.8
    Governing Law. All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and enforced in
accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all Proceedings concerning
the interpretations, enforcement and defense of the transactions contemplated by this
Agreement and any other Transaction Documents (whether brought against a party hereto or
its respective Affiliates, employees or agents) shall be commenced exclusively in the New
York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction
of the New York Courts for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein (including with
respect to the enforcement of the any of the Transaction Documents), and hereby
irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not
personally subject to the jurisdiction of any such New York Court, or that such
Proceeding has been commenced in an improper or inconvenient forum. Each party hereto
hereby irrevocably waives personal service of process and consents to process being
served in any such Proceeding by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect
for 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 hereto hereby irrevocably waives, to the fullest extent permitted by
applicable law, any and all right to trial by jury in any legal proceeding arising out of
or relating to this Agreement or the transactions contemplated hereby. If either party
shall commence a Proceeding to enforce any provisions of a Transaction Document, then the
prevailing party in such Proceeding shall be reimbursed by the other party for its
reasonable attorneys fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such Proceeding.

---

7.9
    Execution. This Agreement may be executed in two or more counterparts, all of
which when taken together shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to the other
party, it being understood that both parties need not sign the same counterpart. In the
event that any signature is delivered by facsimile transmission, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf such
signature is executed) with the same force and effect as if such facsimile signature page
were an original thereof.

7.10
    Severability. If any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect, the validity and enforceability of the remaining terms and
provisions of this Agreement shall not in any way be affected or impaired thereby and the
parties will attempt to agree upon a valid, legal and enforceable provision that is a
reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

7.11
    Replacement of Notes and Conversion Shares. If any certificate or instrument
evidencing any Note or Conversion Share is mutilated, lost, stolen or destroyed, the
Company shall issue or cause to be issued in exchange and substitution for and upon
cancellation thereof, or in lieu of and substitution therefor, a new certificate or
instrument, but only upon receipt of evidence reasonably satisfactory to the Company of
such loss, theft or destruction and customary and reasonable indemnity, if requested. The
applicants for a new certificate or instrument under such circumstances shall also pay
any reasonable third-party costs associated with the issuance of such replacement Notes
or Conversion Shares. If a replacement certificate or instrument evidencing any Notes or
Conversion Shares is requested due to a mutilation thereof, the Company may require
delivery of such mutilated certificate or instrument as a condition precedent to any
issuance of a replacement.

7.12
    Remedies. In addition to being entitled to exercise all rights provided herein or
granted by law, including recovery of damages, each of the Lenders and the Company will
be entitled to specific performance under the Transaction Documents. The parties agree
that monetary damages may not be adequate compensation for any loss incurred by reason of
any breach of obligations described in the foregoing sentence and hereby agrees to waive
in any action for specific performance of any such obligation the defense that a remedy
at law would be adequate.

---

7.13
    Independent Nature of Lenders Obligations and Rights. The obligations of
each Lender under any Transaction Document are several and not joint with the obligations
of any other Lender, and no Lender shall be responsible in any way for the performance of
the obligations of any other Lender under any Transaction Document. The decision of each
Lender to purchase Securities pursuant to the Transaction Documents has been made by such
Lender independently of any other Lender. Nothing contained herein or in any Transaction
Document, and no action taken by any Lender pursuant thereto, shall be deemed to
constitute the Lenders as a partnership, an association, a joint venture or any other
kind of entity, or create a presumption that the Lenders are in any way acting in concert
or as a group with respect to such obligations or the transactions contemplated by the
Transaction Documents. Except as set forth in Section 4.11, each Lender acknowledges that
no other Lender has acted as agent for such Lender in connection with making its
investment hereunder and that no Lender will be acting as agent of such Lender in
connection with monitoring its investment in the Securities or enforcing its rights under
the Transaction Documents. Each Lender 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
Lender to be joined as an additional party in any proceeding for such purpose. The
Company acknowledges that each of the Lenders has been provided with the same Transaction
Documents for the purpose of closing a transaction with multiple Lenders and not because
it was required or requested to do so by any Lender.

7.14
    Limitation of Liability. Notwithstanding anything herein to the contrary, the
Company acknowledges and agrees that the liability of a Lender arising directly or
indirectly, under any Transaction Document of any and every nature whatsoever shall be
satisfied solely out of the assets of such Lender, and that no trustee, officer, other
investment vehicle or any other Affiliate of such Lender or any investor, shareholder or
holder of shares of beneficial interest of such a Lender shall be personally liable for
any liabilities of such Lender.
