is required to obtain any consent, waiver, authorization or order of, give any
notice to, or make any filing or registration with, any court or other federal,
state, local or other governmental authority or other Person in connection with
the execution, delivery and performance by the Company of the Transaction
Documents, other than the filing of the Certificate of Designations and required
federal and state securities filings and such filings and approvals as are
required to be made or obtained under the applicable Trading Market rules in
connection with the transactions contemplated hereby, each of which has been, or
(if not yet required to be filed) shall be, timely filed.

        --------------------------
when issued and paid for in accordance with the applicable Transaction
Documents, will be duly and validly issued, fully paid and nonassessable, free
and clear of all Liens.  The Company has reserved from its duly authorized

issuance of the Securities at least equal to the number of Securities which
could be issued pursuant to the terms of the Transaction Documents, based on the
then-anticipated exercise prices of the Warrant.

Stock all of which have been waived, no Person has any right of first refusal,
preemptive right, right of participation, or any similar right to participate in

any shares of Common Stock, or contracts, commitments, understandings or
arrangements by which the Company or any Subsidiary is or may become bound to
issue additional shares of Common Stock or securities convertible into or
exercisable for shares of Common Stock.  The issuance and sale of the Securities
will not obligate the Company to issue shares of Common Stock or other
securities to any Person (other than Investor) and will not result in a right of
any holder of Company securities to adjust the exercise, conversion, exchange,
or reset price under such securities. All of the outstanding shares of capital
stock of the Company are validly issued, fully paid and nonassessable, have been
issued in compliance with all federal and state securities laws, and none of
such outstanding shares was issued in violation of any preemptive rights or
similar rights to subscribe for or purchase securities.  No further approval or
authorization of any stockholder, the Board of Directors of the Company or
others is required for the issuance and sale of the Securities.  There are no

marketable title in all personal property owned by them that is material to the
business of the Company and each Subsidiary, in each case free and clear of all
Liens, except for Liens that 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 each Subsidiary and Liens for the payment of
federal, state or other taxes, the payment of which is neither delinquent nor
subject to penalties.  Any real property and facilities held under lease by the
Company and each Subsidiary are held by them under valid, subsisting and
enforceable leases of which the Company and each Subsidiary are in compliance.

(o)     Patents and Trademarks.  The Company and each Subsidiary have, or have
        ----------------------
rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, copyrights, licenses and other similar
rights that are necessary or material for use in connection with their
respective businesses as described in the SEC Reports and which the failure to
so have could have a Material Adverse Effect (collectively, the "Intellectual
                                                                 ------------
Property Rights").  Neither the Company nor any Subsidiary has received a
---------------
written notice that the Intellectual Property Rights used by the Company or any
Subsidiary violates or infringes upon the rights of any Person.  Except as set
forth on Section 4.1(j) to the Disclosure Schedule, to the knowledge of the
Company, all such Intellectual Property Rights are enforceable and there is no
existing infringement by another Person of any of the Intellectual Property
Rights of the Company or each Subsidiary.

(p)     Insurance.  The Company and each Subsidiary are insured by insurers of
        ---------
recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which the Company and
each Subsidiary are engaged, including but not limited to directors and officers
insurance coverage at least equal to the Maximum Placement.  To the best of
Company's knowledge, such insurance contracts and policies are accurate and
complete.  Neither the Company nor any Subsidiary has any reason to believe that
it will not be able to renew its existing insurance coverage as and when such
coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business without a significant increase in cost.

(q)     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
knowledge of the Company, 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
knowledge of the Company, any entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner, in each case in excess of $120,000 other than (i) for payment of salary
or consulting fees for services rendered, (ii) reimbursement for expenses
incurred on behalf of the Company and (iii) for other employee benefits,
including stock option agreements under any equity incentive plan of the
Company.

(r)     Sarbanes-Oxley; Internal Accounting Controls.  The Company is in
        --------------------------------------------
material compliance with all provisions of the Sarbanes-Oxley Act of 2002, which
are applicable to it as of the date of the Commitment Closing.  The Company and
each Subsidiary 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 GAAP 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-15(e) and 15d-15(e)) for the
Company and designed such disclosure controls and procedures to ensure that
material information relating to the Company, including its 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 disclosure controls and procedures as of the date 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 Company's 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 accounting controls or its disclosure controls and procedures or, to
the Company's knowledge, in other factors that could materially affect the
Company's internal accounting controls or its disclosure controls and
procedures.

(s)     Certain Fees.  Except for the payment of the Commitment Fee or as set
        ------------
forth on Section 4.1(s) to the Disclosure Schedule, 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.  Investor shall have no obligation with respect to any fees or with
respect to any claims made by or on behalf of other Persons for fees of a type
contemplated in this Section 4.1(s) (including without limitation as set forth
                     --------------
on Section 4.1(s) to the Disclosure Schedule) that may be due in connection with
   --------------
the transactions contemplated by this Agreement or the other Transaction
Documents.

(t)     Private Placement. Assuming the accuracy of Investor representations and
        -----------------
warranties set forth in Section 4.2, no registration under the Act is required
                        ------------
for the offer and sale of the Securities by the Company to Investor as
contemplated hereby. The issuance and sale of the Securities hereunder does not
contravene the rules and regulations of any Trading Market.

(u)     Investment Company. The Company is not, and is not an Affiliate of, and
        ------------------
immediately after receipt of payment for the Securities, will not be or be an
Affiliate of, an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.  The Company shall conduct its business in a
manner so that it will not become subject to the Investment Company Act.

(v)     Registration Rights.  No Person (other than Investor pursuant to the
        -------------------
Transaction Documents) has any right to cause the Company to effect the
registration under the Act of any securities of the Company.

(w)     Listing and Maintenance Requirements.  The Common Stock is registered
        ------------------------------------
pursuant to Section 12 of the Exchange Act, and the Company has taken no action
designed to, or which to its knowledge is likely to have the effect of,
terminating the registration of the Common Stock under the Exchange Act nor has
the Company received any notification that the SEC is contemplating terminating
such registration.  The Company has not, in the 12 months preceding the
Effective Date, received notice from any Trading Market on which the Common
Stock is or has been listed or quoted to the effect that the Company is not in
compliance with the listing or maintenance requirements of such Trading Market.
The Company is, and has no reason to believe that it will not in the foreseeable
future continue to be, in compliance with all such listing and maintenance
requirements.

(x)     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 Company's Certificate of Incorporation (or similar
charter documents) or the laws of its state of incorporation that is or could
become applicable to Investor as a result of Investor and the Company fulfilling
their obligations or exercising their rights under the Transaction Documents,
including without limitation the Company's issuance of the Securities and
Investor's ownership of the Securities.

(y)     Disclosure; Non-Public Information.  Except with respect to the
        ----------------------------------
information that will be, and to the extent that it actually is timely publicly
disclosed by the Company pursuant to Section 2.2(c)(i), and notwithstanding any
                                     -----------------
other provision in this Agreement or the other Transaction Documents, neither
the Company nor any other Person acting on its behalf has provided Investor or
its agents or counsel with any information that constitutes or might constitute
material, non-public information, including without limitation this Agreement
and the Exhibits, Appendices and Schedules hereto, unless prior thereto Investor
shall have executed a written agreement regarding the confidentiality and use of
such information.  The Company understands and confirms that neither Investor
nor any Affiliate of Investor shall have any duty of trust or confidence that is
owed directly, indirectly, or derivatively to the Company or the shareholders of
the Company or to any other Person who is the source of material non-public
information regarding the Company.  No information contained in the Disclosure
Schedules constitutes material non-public information.  There is no adverse
material information regarding the Company that has not been publicly disclosed
prior to the Effective Date.  The Company understands and confirms that Investor
will rely on the foregoing representations and covenants in effecting
transactions in securities of the Company.  All disclosure provided to Investor
regarding the Company, its business and the transactions contemplated hereby,
including the Disclosure Schedules to this Agreement, furnished by or on behalf
of the Company with respect to the representations and warranties made herein
are true and correct in all material respects and do not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading.

(z)     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 security or solicited any offers to buy any security,
under circumstances that would cause this offering of the Securities to be
integrated with prior offerings by the Company for purposes of the Act or which
could violate any applicable stockholder approval provisions, including, without
limitation, under the rules and regulations of the Trading Market.

(aa)     Financial Condition.  As set forth in the SEC Reports, the Company
         -------------------
anticipates that all cash resources will be expended by early in the first
quarter of 2010 and, if unable to raise additional financing, the Company may be
required to: (1) reduce spending plans, (2) license products or technologies
that the Company would otherwise seek to commercialize to third parties, and/or
(3) sell certain assets.  In connection with the transactions contemplated by
the Transaction Documents: (i) the Company has paid undisputed debts as they
matured for at least one year prior to the Effective Date, (ii) the Company will
not be rendered insolvent by such transactions, (iii) after giving effect to
such transactions, the Company will be able to pay its short term debts as they
mature, (iv) such transactions will not cause the Company to be left with
unreasonably small capital for the business in which it is engaged and proposes
to be engaged, (v) the Company did not and does not have any intent to hinder,
delay, or defraud any of its creditors, (vi) the Company has a valid business
reason for entering into such transactions, and (vii) the Company is receiving
new value and consideration therefor constituting reasonably equivalent value
and fair market value consideration.

(bb)     Tax Status.  The Company and each of its Subsidiaries has made or filed
         ----------
all federal, state and foreign income and all other tax returns, reports and
declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provisions reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply.  There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.  The Company has not executed a
waiver with respect to the statute of limitations relating to the assessment or
collection of any foreign, federal, statue or local tax.  None of the Company's
tax returns is presently being audited by any taxing authority.

(cc)     No General Solicitation or Advertising.  Neither the Company nor, to
         --------------------------------------
the knowledge of the Company, any of its directors or officers (i) has conducted
or will conduct any general solicitation (as that term is used in Rule 502(c) of
Regulation D) or general advertising with respect to the sale of the Securities,
or (ii) made any offers or sales of any security or solicited any offers to buy
any security under any circumstances that would require registration of the
Securities under the Act or made any "directed selling efforts" as defined in
Rule 902 of Regulation S.

(dd)     Foreign Corrupt Practices.  Neither the Company, nor to the knowledge
         -------------------------
of the Company, any agent or other person acting on behalf of the Company, has
(i) directly or indirectly, used any corrupt funds for unlawful contributions,
gifts, entertainment or other unlawful expenses related to foreign or domestic
political activity, (ii) made any unlawful payment to foreign or domestic
government officials or employees or to any foreign or domestic political
parties or campaigns from corporate funds, (iii) failed to disclose fully any
contribution made by the Company (or made by any person acting on its behalf of
which the Company is aware) which is  in violation of law, or (iv) violated in
any material respect any provision of the Foreign Corrupt Practices Act of 1977,
as amended.

(ee)     Acknowledgment Regarding Investor's Purchase of Securities.  The
         ----------------------------------------------------------
Company acknowledges and agrees that Investor is acting solely in the capacity
of arm's length purchaser with respect to this Agreement and the transactions
contemplated hereby.  The Company further acknowledges that Investor is not
acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to this Agreement and the transactions contemplated
hereby and any statement made by Investor or any of its representatives or
agents in connection with this Agreement and the transactions contemplated
hereby is not advice or a recommendation and is merely incidental to Investor's
purchase of the Securities.  The Company further represents to Investor that the
Company's decision to enter into this Agreement has been based solely on the
independent evaluation of the Company and its representatives.

(ff)     Accountants.  The  Company's  accountants  are  set  forth  in  the SEC
         -----------
Reports  and  such  accountants  are an independent registered public accounting
firm  as  required  by  the  SEC  Guidance.

(gg)     No Disagreements with Accountants and Lawyers.  There are no
         ---------------------------------------------
disagreements of any kind presently existing, or reasonably anticipated by the
Company to arise, between the accountants and lawyers formerly or presently
employed by the Company, and the Company is current with respect to any fees
owed to its accountants and lawyers, except for any past-due amounts that may be
owed in the ordinary course of business.

(hh)     Registration Statements and Prospectuses.
         ----------------------------------------

         (i)    The offer and sale of the Common Shares as contemplated hereby
complies with the requirements of Rule 415 under the Act.

         (ii)   The Company has not, directly or indirectly, used or referred
to any "free writing prospectus" (as defined in Rule 405 under the Act) except
in compliance with Rules 164 and 433 under the Act.

         (iii)  The Company is not an "ineligible issuer" (as defined in Rule
405 under the Act) as of the eligibility determination date for purposes of
Rules 164 and 433 under the Act with respect to the offering of the Common
Shares contemplated by any Registration Statement filed or to be filed, without
taking into account any determination by the SEC pursuant to Rule 405 under the
Act that it is not necessary under the circumstances that the Company be
considered an "ineligible issuer."

(ii)     Section 5 Compliance. No representation or warranty or other statement
         --------------------
made by Company in the Transaction Documents contains any untrue statement
or omits to state a material fact necessary to make any of them, in light of the
circumstances in which it was made, not misleading.  The Company is not aware of
any facts or circumstances that would cause the transactions contemplated by the
Transaction Documents, when consummated, to violate Section 5 of the Act or
other federal or state securities laws or regulations.

4.2     REPRESENTATIONS AND WARRANTIES OF INVESTOR. Investor hereby represents
        ------------------------------------------
and warrants as of the Effective Date as follows:

(a)     Organization; Authority.  Investor is an entity duly incorporated,
        -----------------------
validly existing and in good standing under the laws of the jurisdiction of its
organization with full right, company power and authority to enter into and
to consummate the transactions contemplated by the Transaction Documents and
otherwise to carry out its obligations thereunder.  The execution, delivery and
performance by Investor of the transactions contemplated by this Agreement have
been duly authorized by all necessary company or similar action on the part of
Investor.  Each Transaction Document to which it is a party has been (or will
be) duly executed by Investor, and when delivered by Investor in accordance with
the terms hereof, will constitute the valid and legally binding obligation of
Investor, enforceable against it in accordance with its terms, except (i) as
limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors' rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable
remedies and (iii) insofar as indemnification and contribution provisions may be
limited by applicable law.

(b)     Investor Status.  At the time Investor was offered the Securities, it
        ---------------
was, and at the Effective Date it is an "accredited investor" as defined in Rule
501(a) under the Act.

(c)     Experience of Investor.  Investor, either alone or together with its
        ----------------------
representatives, has such knowledge, sophistication and experience in business
and financial matters so as to be capable of evaluating the merits and risks of
the prospective investment in the Securities, and has so evaluated the merits
and risks of such investment.  Investor is able to bear the economic risk of an
investment in the Securities and, at the present time, is able to afford a
complete loss of such investment.

(d)     General  Solicitation.  Investor  is  not purchasing the Securities as a
        ---------------------
result  of  any  advertisement, article, notice or other communication regarding
the  Securities  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.

     The Company acknowledges and agrees that Investor does not make or has not
made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in this Section 4.2.
                                                                    -----------

                                   ARTICLE 5
                         OTHER AGREEMENTS OF THE PARTIES

5.1     TRANSFER RESTRICTIONS
        ---------------------
(a)     The Securities may only be disposed of in compliance with state and
federal securities laws.  In connection with any transfer of Securities other
than (i) pursuant to an effective Registration Statement or Rule 144, (ii) to
the Company, (iii) to an Affiliate of Investor, or (iv) in connection with a
pledge as contemplated in Section 5.1(b), the Company may require the transferor
                          --------------
thereof to provide to the Company an opinion of Luce Forward Hamilton &
Scripps LLP ("Luce Forward"), or other counsel selected by the transferor and
              ------------
reasonably acceptable to the Company, to the effect that such transfer does not
require registration of such transferred Securities under the Act.

(b)     Investor  agrees  to  the  imprinting,  so  long  as is required by this
Section 5.1,  of  the  following  legend, or substantially similar legend, on
-----------
any certificate  evidencing  Securities  other  than  DWAC  Shares:

NEITHER  THESE  SECURITIES  NOR  THE  SECURITIES INTO WHICH THESE SECURITIES ARE
EXERCISABLE  HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR
THE  SECURITIES  COMMISSION  OF  ANY  STATE  IN  RELIANCE UPON AN EXEMPTION FROM
REGISTRATION  UNDER  THE  SECURITIES  ACT  OF  1933, AS AMENDED (THE "SECURITIES
ACT"),  AND,  ACCORDINGLY,  MAY  NOT  BE  OFFERED  OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE  REGISTRATION  STATEMENT  UNDER  THE  SECURITIES ACT OR PURSUANT TO AN
AVAILABLE  EXEMPTION  FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS  OF  THE  SECURITIES  ACT  AND  IN ACCORDANCE WITH APPLICABLE STATE
SECURITIES  LAWS.  THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF
THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR
OTHER  LOAN  SECURED  BY  SUCH  SECURITIES.

     The Company agrees to cause such legend to be removed immediately upon
effectiveness of a Registration Statement, or when any Common Shares are
eligible for sale under Rule 144 and, if requested by Investor or the transfer
agent, to promptly provide at the Company's expense a legal opinion of counsel
to the Company confirming that such legend may be removed.  Company further
acknowledges and agrees that Investor may from time to time pledge pursuant to a
bona fide margin agreement with a registered broker-dealer or grant a security
interest in some or all of the Securities to a financial institution that is an
"accredited investor" as defined in Rule 501(a) under the Act and who agrees to
be bound by the provisions of this Agreement and, if required under the terms of
such arrangement, Investor may transfer pledged or secured Securities to the
pledgees or secured parties.  Such a pledge or transfer would not be subject to
approval of the Company and no legal opinion of legal counsel of the pledgee,
secured party or pledgor shall be required in connection therewith.  Further, no
notice shall be required of such pledge.  At Investor's reasonable expense, the
Company will execute and deliver such documentation as a pledgee or secured
party of Securities may reasonably request in connection with a pledge or
transfer of the Securities.

5.2     FURNISHING OF INFORMATION
        -------------------------
As long as Investor owns Securities, the Company covenants to timely file (or
obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the Effective Date
pursuant to the Exchange Act.  Upon the request of Investor, the Company shall
deliver to Investor a written certification of a duly authorized officer as to
whether it has complied with the preceding sentence. As long as Investor owns
Securities, if the Company is not required to file reports pursuant to such
laws, it will prepare and furnish to Investor and make publicly available in
accordance with Rule 144(c) such information as is required for Investor to sell
the Securities under Rule 144.  The Company further covenants that it will take
such further action as any holder of Securities may reasonably request, all to
the extent required from time to time to enable such Person to sell such
Securities without registration under the Act within the limitation of the
exemptions provided by Rule 144.

5.3     INTEGRATION
        -----------
The Company shall not sell, offer for sale or solicit offers to buy or
otherwise negotiate in respect of any security (as defined in Section 2 of the
Act) that would be integrated with the offer or sale of the Securities in a
manner that would require the registration under the Act of the sale of the
Securities to Investor or that would be integrated with the offer or sale of the
Securities for purposes of the rules and regulations of any Trading Market such
that it would require stockholder approval prior to the closing of such other
transaction unless stockholder approval is obtained before the closing of such
subsequent transaction.

5.4     SECURITIES LAWS DISCLOSURE; PUBLICITY
        -------------------------------------
The Company shall timely file a Current Report on Form 8-K as required by
this Agreement, and in the Company's discretion shall file a press release, in
each case reasonably acceptable to Investor, disclosing the material terms of
the transactions contemplated hereby.  The Company and Investor shall consult
with each other in issuing any press releases with respect to the transactions
contemplated hereby, and neither the Company nor Investor shall issue any such
press release or otherwise make any such public statement without the prior
consent of the Company, with respect to any such press release of Investor, or
without the prior consent of Investor, with respect to any such press release of
the Company, which consent shall not unreasonably be withheld or delayed, except
if such disclosure is required by law or Trading Market regulations, in which
case the disclosing party shall promptly provide the other party with prior
notice of such public statement or communication.  Notwithstanding the
foregoing, the Company shall not publicly disclose the name of Investor, or
include the name of Investor in any filing with the SEC or any regulatory agency
or Trading Market, without the prior written consent of Investor, except (i) as
contained in the Current Report on Form 8-K and press release described above,
(ii) as required by federal securities law in connection with any registration
statement under which the Common Shares are registered, (iii) to the extent such
disclosure is required by law or Trading Market regulations, in which case the
Company shall provide Investor with prior notice of such disclosure, or (iv) to
the extent such disclosure is required in any SEC Report filed by the Company.

5.5     SHAREHOLDERS RIGHTS PLAN
        ------------------------
No claim will be made or enforced by the Company or, to the knowledge of the
Company, any other Person that Investor is an "Acquiring Person" under any
shareholders rights plan or similar plan or arrangement in effect or hereafter
adopted by the Company, or that Investor could be deemed to trigger the
provisions of any such plan or arrangement, by virtue of receiving Securities
under the Transaction Documents or under any other agreement between the Company
and Investor. The Company shall conduct its business in a manner so that it will
not become subject to the Investment Company Act of 1940, as amended.

5.6     NON-PUBLIC INFORMATION
        ----------------------
The Company covenants and agrees that neither it nor any other Person acting
on its behalf will provide Investor or its agents or counsel with any
information that the Company believes or reasonably should believe constitutes
material non-public information, unless prior thereto Investor shall have
executed a written agreement regarding the confidentiality and use of such
information.  On and after the Effective Date, except as may be set forth in a
written and executed confidentiality agreement, neither Investor nor any
Affiliate Investor shall have any duty of trust or confidence that is owed
directly, indirectly, or derivatively, to the Company or the shareholders of the
Company, or to any other Person who is the source of material non-public
information regarding the Company.  The Company understands and confirms that
Investor shall be relying on the foregoing in effecting transactions in
securities of the Company.

5.7     REIMBURSEMENT
        -------------
If Investor becomes involved in any capacity in any proceeding by or against
any Person who is a stockholder of the Company (except as a result of sales,
pledges, margin sales and similar transactions by Investor to or with any
current stockholder), solely as a result of Investor's acquisition of the
Securities under this Agreement, the Company will reimburse Investor for its
reasonable legal and other reasonable expenses (including the reasonable cost of
any investigation preparation and travel in connection therewith) incurred in
connection therewith, as such expenses are incurred, or will assume the defense
of Investor in such matter.  The reimbursement obligations of the Company under
this Section 5.7 shall be in addition to any liability which the Company may
     -----------
otherwise have, shall extend upon the same terms and conditions to any
Affiliates of Investor who are actually named in such action, proceeding or
investigation, and partners, directors, agents, employees and controlling
persons (if any), as the case may be, of Investor and any such Affiliate, and
shall be binding upon and inure to the benefit of any successors, assigns, heirs
and personal representatives of the Company, Investor and any such Affiliate and
any such Person.  The Company also agrees that neither Investor nor any such
Affiliates, partners, directors, agents, employees or controlling persons shall
have any liability to the Company or any Person asserting claims on behalf of or
in right of the Company solely as a result of acquiring the Securities under
this Agreement.

5.8     INDEMNIFICATION OF INVESTOR
        ---------------------------
(a)     Company Indemnification Obligation.  Subject to the provisions of this
        ----------------------------------
Section 5.8, the Company will indemnify and hold Investor and any Warrant
-----------

shareholders, partners, employees, agents, and any person who controls Investor

Act (collectively, the "Investor Parties" and each an "Investor Party"),
                        ----------------               --------------
harmless from any and all losses, liabilities, obligations, claims,
contingencies, damages, reasonable costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys' fees and
costs of investigation (collectively, "Losses") that any Investor Party may
                                       ------
suffer or incur as a result of or relating to (i) any breach of any of the
representations, warranties, covenants or agreements made by the Company in this
Agreement or in the other Transaction Documents, (ii) any action instituted
against any Investor Party, or any of them or their respective Affiliates, by
any stockholder of the Company who is not an Affiliate of an Investor Party,
with respect to any of the transactions contemplated by the Transaction
Documents (unless such action is based upon a breach of Investor's
representations, warranties or covenants under the Transaction Documents or any
agreements or understandings Investor may have with any such stockholder or any
violations by Investor of state or federal securities laws or any conduct by
Investor which constitutes fraud, gross negligence, willful misconduct or
malfeasance), (iii) any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement (or in a Registration
Statement as amended by any post-effective amendment thereof by the Company), or
arising out of or based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and/or (iv) any untrue statement or alleged untrue
statement of a material fact included in any Prospectus (or any amendments or
supplements to any Prospectus), in any free writing prospectus, in any "issuer
information" (as defined in Rule 433 under the Act) of the Company, or in any
Prospectus together with any combination of one or more of the free writing
prospectuses, if any, or arising out of or based upon any omission or alleged
omission to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

(b)     Indemnification Procedures.  If any action shall be brought against an
        --------------------------
Investor Party in respect of which indemnity may be sought pursuant to this
Agreement, such Investor Party shall promptly notify the Company in writing, and
the Company shall have the right to assume the defense thereof with counsel of
its own choosing.  The Investor Parties shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the Investor Parties
except to the extent that (i) the employment thereof has been specifically
authorized by the Company in writing, (ii) the Company has failed after a
reasonable period of time to assume such defense and to employ counsel or (iii)
in such action there is, in the reasonable opinion of such separate counsel, a
material conflict with respect to the dispute in question on any material issue
between the position of the Company and the position of the Investor Parties
such that it would be inappropriate for one counsel to represent the Company and
the Investor Parties.  The Company will not be liable to the Investor Parties
under this Agreement (i) for any settlement by an Investor Party effected
without the Company's prior written consent, which shall not be unreasonably
withheld or delayed; or (ii) to the extent, but only to the extent that a loss,
claim, damage or liability is either attributable to Investor's breach of any of
the representations, warranties, covenants or agreements made by Investor in
this Agreement or in the other Transaction Documents.

5.9     RESERVATION OF SECURITIES
        -------------------------
The Company shall maintain a reserve from its duly authorized shares of
Common Stock for issuance pursuant to the Transaction Documents in such amount
as may be required to fulfill its obligations in full under the Transaction
Documents.

5.10     LIMITED STANDSTILL
         ------------------
The Company will deliver to Investor on or before each Tranche Closing Date,
and will honor and enforce, and will take reasonable actions to assist Investor
in enforcing, the provisions of, the Lock-Up Agreements with the Company's
officers, directors and beneficial owners of 10% or more of the Common Stock.

5.11     PROSPECTUS AVAILABILITY AND CHANGES
         -----------------------------------
The Company will make available to Investor upon request, and thereafter from
time to time will furnish Investor, as many copies of any Prospectus (or of the
Prospectus as amended or supplemented if the Company shall have made any
amendments or supplements thereto after the effective date of the applicable
Registration Statement) as Investor may request for the purposes contemplated by
the Act; and in case Investor is required to deliver  a prospectus after the
nine-month period referred to in Section 10(a)(3) of the Act in connection with
the sale of the Common Shares, or after the time a post-effective amendment to
the applicable Registration Statement is required pursuant to Item 512(a) of
Regulation S-K under the Act, the Company will prepare, at its expense, promptly
upon request such amendment or amendments to the Registration Statement and the
Prospectus as may be necessary to permit compliance with the requirements of
Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as
the case may be.  The Company will advise Investor promptly of the happening of
any event within the time during which a Prospectus is required to be delivered
under the Act which could require the making of any change in the Prospectus
then being used so that the Prospectus would not include an untrue statement of
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they are made,
not misleading, and to advise Investor promptly if, during such period, it shall
become necessary to amend or supplement any Prospectus to cause such Prospectus
to comply with the requirements of the Act, and in each case, during such time,
to prepare and furnish, at the Company's expense, to Investor promptly such
amendments or supplements to such Prospectus as may be necessary to reflect any
such change or to effect such compliance.  The Company shall have no obligation
to separately advise Investor of, or deliver copies to Investor of, the SEC
Reports, all of which Investor shall be deemed to have notice of.

5.12     REQUIRED APPROVAL.  No transactions contemplated under this Agreement
         -----------------
or the Transaction Documents shall be consummated for an amount that would
require approval by any Trading Market or Company stockholders under any
approval provisions, rules or regulations of any Trading Market applicable to
the Company, unless and until such approval is obtained.  Company shall use best
efforts to obtain any required approval as soon as possible.

5.13     ACTIVITY RESTRICTIONS.  For so long as Investor or any of its
         ---------------------
Affiliates holds any Preferred Shares, Commitment Fee Shares, Warrant, Warrant
Shares, or DWAC Shares, neither Investor nor any Affiliate will: (i) vote any
shares of Common Stock owned or controlled by it, solicit any proxies, or seek
to advise or influence any Person with respect to any voting securities of the
Company; (ii) engage or participate in any actions, plans or proposals which
relate to or would result in (a) acquiring additional securities of the Company,
alone or together with any other Person, which would result in beneficially
owning or controlling more than 9.99% of the total outstanding Common Stock or
other voting securities of the Company, (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving Company
or any of its subsidiaries, (c) a sale or transfer of a material amount of
assets of the Company or any of its subsidiaries, (d) any change in the present
board of directors or management of the Company, including any plans or
proposals to change the number or term of directors or to fill any existing
vacancies on the board, (e) any material change in the present capitalization or
dividend policy of the Company, (f) any other material change in the Company's
business or corporate structure, including but not limited to, if the Company is
a registered closed-end investment company, any plans or proposals to make any
changes in its investment policy for which a vote is required by Section 13 of
the Investment Company Act of 1940, (g) changes in the Company's charter, bylaws
or instruments corresponding thereto or other actions which may impede the
acquisition of control of the Company by any Person, (h) causing a class of
securities of the Company to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association, (i) a class of equity securities of
the Company becoming eligible for termination of registration pursuant  to
Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement
similar to any of those enumerated above; or (iii) request the Company or its
directors, officers, employees, agents or representatives to amend or waive any
provision of this Section 5.13.
                  ------------

5.14     REGISTRATION STATEMENTS AND PROSPECTUSES.
         ----------------------------------------
(a)     The Company will use its best efforts to file within 45 (forty-five)
calendar days after the Effective Date (or as soon as possible thereafter), to
cause to become effective as soon as possible thereafter, and to remain
effective until all Common Shares have been sold or are Rule 144 Eligible, a
Registration Statement for the resale of all Common Shares issued or  issuable
hereunder including without limitation all Warrant Shares underlying the Warrant
or such lesser number of Common Shares permitted to be registered pursuant
to SEC Guidance.  Each Registration Statement shall comply when it becomes
effective, and, as amended or supplemented, at the time of any Tranche Notice
Date, Tranche Closing Date, or issuance of any Common Shares, and at all times
during which a prospectus is required by the Act to be delivered in connection
with any sale of Common Shares, will comply, in all material respects, with the
requirements of the Act.

(b)     Each Registration Statement, as of its respective effective time, will
not, as applicable, contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading.

(c)     Each Prospectus will comply, as of its date and the date it will be
filed with the SEC,  and, at the time of any Tranche Notice Date, Tranche
Closing Date, or issuance of any Common Shares, and at all times during which a
prospectus is required by the Act to be delivered in connection with any sale of
Common Shares, will comply, in all material respects, with the requirements of
the Act.

(d)     At no time during the period that begins on the date a Prospectus is
filed with the SEC and ends at the time a Prospectus is no longer required by
the Act to be delivered in connection with any sale of Common Shares will any
such Prospectus, as then amended or supplemented, include an untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

(e)     Each Registration Statement will meet, and the offering and sale of the
Common Shares as contemplated hereby will comply with, the requirements of Rule
415 under the Act.

(f)     The Company will not, directly or indirectly, use or refer to any "free
writing prospectus" (as defined in Rule 405 under the Act) except in compliance
with Rules 164 and 433 under the Act.

(g)     The Company will not be an "ineligible issuer" (as defined in Rule 405
under the Act) as of the eligibility determination date for purposes of Rules
164 and 433 under the Act with respect to the offering of the Common Shares
contemplated by any Registration Statement that is filed, without taking into
account any determination by the SEC pursuant to Rule 405 under the Act that it
is not necessary under the circumstances that the Company be considered an
"ineligible issuer."

(h)     If (i) there is material non-public information regarding the Company
which the Company's Board of Directors reasonably determines not to be in the
Company's best interest to disclose and which the Company is not otherwise
required to disclose and which the Company would be required to disclose under
the Registration Statement, or (ii) there is a significant business opportunity
(including, but not limited to, the acquisition or disposition of assets other
than in the ordinary course of business or any merger, consolidation, tender
offer or other similar transaction) available to the Company which the Board of
Directors reasonably determines not to be in the Company's best interest to
disclose and which the Company would be required to disclose under the
Registration Statement, and in the case of either (i) or (ii) the Company
reasonably believes it is required under SEC Guidance to postpone or suspend
filing or effectiveness of the Registration Statement,  the Company shall
immediately notify Investor in writing that the Registration Statement may not
be used in connection with any sales of the Company's securities for a period
not to exceed 10 consecutive days (a "Blackout Period"), provided that the
aggregate of all Blackout Periods may not exceed 30 days during any 12 month
period.  During a Blackout Period, the Company shall not be permitted to deliver
any Tranche Notices or effect any Tranche Closings.

5.15     INVESTOR DUE DILIGENCE.  Investor shall have the right and opportunity
         ----------------------
to conduct due diligence, at its own expense, with respect to any
Registration Statement or Prospectus in which the name of Investor or any
Affiliate of Investor appears.

5.16     REGISTRATION.  In the event that all Common Shares that Company is
         ------------
required to make available to Investor, including as Warrant Shares upon the
exercise of Warrants, are not, by the one year anniversary of the Effective
Date, made available to Investor as DWAC Shares without restriction on resale
pursuant to (i) an effective Registration Statement (with the number of Warrant
Shares included therein subject to the limitation set forth in Section 5.14(a)
                                                               ---------------
hereof), or (ii) Rule 144 without requiring discharge by payment in full of any
notes given in exchange for any Warrant Shares prior to the sale thereof or
limiting the amount of securities that may be sold, Company shall, at Investor's
election in Investor's sole discretion, exercise the Company's Redemption Option
provided for in Section 6 of the Certificate of Designations to effectuate the
                ---------
repurchase of any outstanding Preferred Shares.

fee payable to counsel for Investor at each Tranche Closing, or as may be

Securities, if any.

No provision of this Agreement may be waived or amended except in a written
instrument signed, in the case of an amendment, by the Company and Investor or,
in the case of a waiver, by the party against whom enforcement of any such
waiver is sought.  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.

6.4     HEADINGS
        --------

        ----------------------
This Agreement shall be binding upon and inure to the benefit of the parties

Agreement or any rights or obligations hereunder without the prior written
consent of Investor, which consent shall not be unreasonably withheld or
delayed.  Investor may assign any or all of its rights under this Agreement (a)

assigns or transfers any Securities provided that such Person agrees in writing
to be bound, with respect to the transferred Securities, by the provisions
hereof that apply to the "Investor".

6.6     NO THIRD-PARTY BENEFICIARIES
        ----------------------------

6.7     GOVERNING LAW; DISPUTE RESOLUTION
        ---------------------------------
All questions concerning the construction, validity, enforcement and
interpretation of the Transaction Documents shall be governed by and construed
and enforced in accordance with the laws of the State of New York, without
regard to the principles of conflicts of law that would require or permit the
application of the laws of any other jurisdiction.  Each party agrees that all
legal 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, directors,
officers, shareholders, employees or agents) shall be commenced exclusively in
the state and federal courts sitting in the City of New York.  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 (including with respect to
the enforcement of any of the Transaction Documents), 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 improper or inconvenient venue for such
proceeding.  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 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.  The parties hereby waive all rights to a trial by jury.  If
either party shall commence an action or proceeding to enforce any provisions of
the Transaction Documents, then the prevailing party in such action or
proceeding shall be reimbursed by the other party for its reasonable attorneys'
fees and other costs and expenses reasonably incurred in connection with the
investigation, preparation and prosecution of such action or proceeding.

6.8     SURVIVAL
        --------
The representations and warranties contained herein shall survive the Closing
and the delivery and exercise of the Securities.

6.9     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 or in a PDF by e-mail 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.

6.10     SEVERABILITY
         ------------
If any provision of this Agreement is held to be invalid 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 and enforceable
provision that is a reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Agreement.

6.11     REPLACEMENT OF SECURITIES
         -------------------------
If any certificate or instrument evidencing any Securities 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 Securities.

6.12     REMEDIES
         --------
In addition to being entitled to exercise all rights provided herein or
granted by law, including recovery of damages, each of Investor 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.
Neither the Company nor Investor shall be liable for special, indirect,
consequential or punitive damages suffered or alleged to be suffered by the
other party or any third party, whether arising from or related to the
Transaction Documents or otherwise.

6.13     PAYMENT SET ASIDE
         -----------------
To the extent that the Company makes a payment or payments to Investor
pursuant to any Transaction Document or Investor enforces or exercises its
rights 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.

6.14     LIQUIDATED DAMAGES
         ------------------
The Company's obligations to pay any partial liquidated damages or other
amounts owing under the Transaction Documents is a continuing obligation of the
Company and shall not terminate until all unpaid partial liquidated damages and
other amounts have been paid notwithstanding the fact that the instrument or
security pursuant to which such partial liquidated damages or other amounts are
due and payable shall have been cancelled.

6.15     TIME OF THE ESSENCE
         -------------------
Time is of the essence with respect to all provisions of this Agreement that
specify a time for performance.

6.16     CONSTRUCTION
         ------------
The parties agree that each of them and/or their respective counsel has
reviewed and had an opportunity to revise the Transaction Documents and,
therefore, the normal rule of construction to the effect that any ambiguities
are to be resolved against the drafting party shall not be employed in the
interpretation of the Transaction Documents or any amendments hereto. 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.

6.17     ENTIRE AGREEMENT
         ----------------
This Agreement, together with the Exhibits, Appendices and Schedules hereto,
contains the entire agreement and understanding of the parties, and supersedes
all prior and contemporaneous agreements, term sheets, letters, discussions,
communications and understandings, both oral and written, which the parties
acknowledge have been merged into this Agreement.  No party, representative,
attorney or agent has relied upon any collateral contract, agreement, assurance,
promise, understanding or representation not expressly set forth hereinabove.
The parties hereby expressly waive all rights and remedies, at law and in
equity, directly or indirectly arising out of or relating to, or which may arise
as a result of, any Person's reliance on any such assurance.

Notice Date, to exercise the Warrant and purchase up to a number of shares of
Common Stock with an Aggregate Exercise Price equal to 135% of the Tranche
Purchase Price for the applicable Tranche Notice.  Attached to this Warrant is a
schedule (the "Warrant Tranche Schedule") that sets forth the issuance date, the
               ------------------------
number of Warrant Shares, and the Exercise Price for each Warrant Tranche.  The
Warrant Tranche Schedule shall be updated by the Company, with an updated copy
provided to the Holder, promptly following each exercise of this Warrant.  No
portion of this Warrant shall vest or be exercisable except under the Warrant
Tranches.

                             EXERCISE OF WARRANT.

1.1     MECHANICS OF EXERCISE.
        ---------------------

1.1.1     Subject to the terms and conditions hereof, this Warrant may be
exercised by the Holder on any day on or after the Issuance Date, in whole or in
part, by (i) delivery of a written notice to the Company, in the form
attached hereto as Appendix 1 (the "Exercise Notice"), of the Holder's election
                                    ---------------
to exercise this Warrant, and (ii) payment to the Company of an amount equal to
the applicable Exercise Price multiplied by the number of Warrant Shares as to
which this Warrant is being exercised (the "Aggregate Exercise Price"), with
                                            ------------------------
such payment made, at Investor's option, (x) in cash or by wire transfer of
immediately available funds, (y) by the issuance and delivery of a recourse
promissory note substantially in the form attached hereto as Appendix 2 (each, a
"Recourse Note"), or (z) if applicable, by cashless exercise pursuant to Section
 -------------                                                           -------
1.3.
---

1.1.2     The Holder shall not be required to deliver the original Warrant in
order to effect an exercise hereunder.  Execution and delivery of the Exercise
Notice with respect to less than all of the Warrant Shares shall have the same
effect as cancellation of the original Warrant and issuance of a new Warrant
evidencing the right to purchase the remaining number of Warrant Shares.

1.1.3     On the Trading Day on which the Company has received each of the
Exercise Notice and the Aggregate Exercise Price (the "Exercise Delivery
                                                       -----------------
Documents") from the Holder by 6:30 p.m. Eastern time, or on the next Trading
---------
Day if the Exercise Delivery Documents are received after 6:30 p.m. Eastern time
or on a non-Trading Day (in each case, the "Exercise Delivery Date"), the
                                            ----------------------
Company shall transmit (i) a facsimile acknowledgment of confirmation of receipt
of the Exercise Delivery Documents to the Holder, and (ii) an electronic copy of
its share issuance instructions to the Holder and to the Company's transfer
agent (the "Transfer Agent"), with such transmissions to comply with the notice
            --------------
provisions contained in Section 6.2 of the Purchase Agreement, and shall
                        -----------
instruct and authorize the Transfer Agent to credit such aggregate number of
freely-tradable Warrant Shares to which the Holder is entitled to receive upon
such exercise to the Holder's or its designee's balance account with The
Depository Trust Company (DTC) through the Fast Automated Securities Transfer
(FAST) Program through its Deposit Withdrawal Agent Commission (DWAC) system,
with such credit to occur no later than 12:00 p.m. Eastern Time on the Trading
Day following the Exercise Delivery Date, time being of the essence; provided,
however, that if the Warrant Shares are not credited as DWAC Shares by 12:00
p.m. Eastern Time on the Trading Day following the Exercise Delivery Date, then
the Tranche Closing Date applicable to the Exercise Notice shall be extended by
one Trading Day for each Trading Day that timely credit of DWAC Shares is not
made.

1.1.4     Upon delivery of the Exercise Delivery Documents, the Holder shall be
deemed for all corporate purposes to have become the holder of record of the
Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date such Warrant Shares are credited to the Holder's DTC
account.  Any Warrant delivered in connection with a Tranche Notice and
exercised by Holder shall be deemed exercised (i) on the Tranche Notice Date, if
exercised by 6:30 p.m. Eastern time on the Tranche Notice Date, or (ii) on the
next Trading Day, if exercised by Investor after 6:30 p.m. Eastern Time on the
Tranche Notice Date or on any other date, in each case with Holder deemed to be
a holder of record as of such date.

1.1.5     If this Warrant is exercised and the number of Warrant Shares
represented by this Warrant is greater than the number of Warrant Shares being
acquired upon such exercise, then the Company shall, as soon as practicable and
in no event later than one Trading Day after such exercise, update the Tranche
Exercise Schedule to reflect the revised number of Warrant Shares for which this
Warrant is then exercisable and deliver a copy of the updated Tranche Exercise
Schedule to the Holder.  No fractional shares of Common Stock are to be issued
upon the exercise of this Warrant, but rather the number of shares of Common
Stock to be issued shall be rounded up to the nearest whole number.  The Company
shall pay any and all taxes which may be payable with respect to the issuance
and delivery of Warrant Shares upon exercise of this Warrant, other than
income-related taxes payable by the Investor.

1.2     ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SHARES.  In addition to
        --------------------------------------------------
other adjustments specified herein, the Exercise Price of this Warrant and the
number of shares of Common Stock issuable upon exercise shall be adjusted as
follows:

1.2.1     EXERCISE PRICE.  The "Exercise Price" per share of Common Stock
          --------------
underlying this Warrant, subject to further adjustment as provided herein, shall
be as follows: (i) with respect to the portion of this Warrant issued on the
Effective Date and until the first Tranche Notice Date, the amount per Warrant
Share set forth on the face of this Warrant, which is equal to Closing Bid Price
for the Common Stock on the Trading Day prior to the Effective Date, and (ii)
with respect to the portion of this Warrant that becomes exercisable on any
Tranche Notice Date (including the first Tranche Notice Date), an amount per
Warrant Share equal to the Closing Bid Price of a share of Common Stock on such
Tranche Notice Date.

1.2.2     NUMBER OF SHARES.  The number of Warrant Shares underlying this
          ----------------
Warrant and each Warrant Tranche, subject to further adjustment as provided
herein, shall be as follows: (i) with respect to the portion of this Warrant
issued on the Effective Date and until the first Tranche Notice Date, the number
of shares set forth on the face of this Warrant, which is a number of shares of
Common Stock equal to the Maximum Placement multiplied by 135%, with the
resulting sum divided by the Closing Bid Price of a share of Common Stock on the
Trading Day prior to the Effective Date, and (ii) with respect to the portion of
this Warrant issued on any Tranche Notice Date including the first Tranche
Notice Date, a number of shares equal to the Tranche Purchase Price set forth in
the applicable Tranche Notice multiplied by 135%, with the resulting sum divided
by the Closing Bid Price of a share of Common Stock on the Tranche Notice Date.
For example, if the Tranche Purchase Price is $1,000,000 and the Closing Bid
Price is $0.50, then the number of Warrant Shares underlying that Warrant
Tranche shall be $1,000,000 x 135% = $1,350,000 divided by $0.50 = 2,700,000
shares of Common Stock.  On each Tranche Notice Date, the number of Warrant
Shares underlying the related Warrant Tranche shall vest and become exercisable,
and the aggregate number of Warrant Shares underlying this Warrant that are
currently exercisable shall automatically adjust up or down to account for the
change in the number of Warrant Shares covered by the new Warrant Tranche and
for any Warrant Shares issued upon any prior or simultaneous exercise of this
Warrant.  If at any time the Holder reasonably believes that the number of
Warrant Shares included in the Registration Statement is not sufficient to cover
all exercises under this Warrant, then the Company shall amend such Registration
Statement to include the additional number of Warrant Shares that may be
required to provide such coverage.

1.3     CASHLESS EXERCISE.  Notwithstanding anything contained herein to the
        -----------------
contrary, if at any time there is not a current, valid and effective
registration statement covering the Warrant Shares that are the subject of the
Exercise Notice (the "Unavailable Warrant Shares"), the Holder may, in its sole
                      --------------------------
discretion, exercise this Warrant in whole or in part and, in lieu of
making the cash payment otherwise contemplated to be made to the Company upon
such exercise in payment of the Aggregate Exercise Price, elect instead to
receive upon such exercise the "Net Number" of shares of Common Stock determined
according to the following formula (a "Cashless Exercise"):

Net Number =     (B-C) x A
                 ---------
                    B

For purposes of the foregoing formula:

A = the total number of shares with respect to which this Warrant is then being
    exercised.

B = the average of the Closing Bid Prices of the shares of Common Stock (as
reported by Bloomberg) for the five (5) consecutive Trading Days ending on the
date immediately preceding the date of the Exercise Notice.

C = the Exercise Price then in effect for the applicable Warrant Shares at the
time of such exercise.

1.4     COMPANY'S FAILURE TO TIMELY DELIVER SECURITIES.  If the Company shall
        ----------------------------------------------
fail, for any reason or for no reason to credit to the Holder's balance account
with DTC, by 12:00 p.m. Eastern time on the Trading Day following the
Exercise Delivery Date, the number of shares of Common Stock to which the Holder
is entitled upon the Holder's exercise of this Warrant, then, in addition to all
other remedies available to the Holder, the Company shall pay in cash to the
Holder on each day after such Trading Day that the issuance of such shares of
Common Stock is not timely effected an amount equal to 1.5% of the product of
(A) the sum of the number of shares of Common Stock not issued to the Holder on
a timely basis and to which the Holder is entitled and (B) the Closing Bid Price
of the shares of Common Stock on the Trading Day immediately preceding the last
possible date which the Company could have issued such shares of Common Stock to
the Holder without violating Section 1.1.  In addition to the foregoing, if
                             -----------
after the Company's receipt of an Exercise Notice the Company shall fail to
timely (pursuant to Section 1.1.3 hereof) credit the Holder's balance account
                    -------------
with DTC for the number of shares of Common Stock to which the Holder is
entitled upon the Holder's exercise hereunder, and the Holder purchases (in an
open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of shares of Common Stock issuable upon
such exercise that the Holder anticipated receiving from the Company, then the
Company shall, within one Trading Day after the Holder's request and in the
Holder's discretion, either (i) pay cash to the Holder in an amount equal to the
Holder's total purchase price (including brokerage commissions, if any) for the
shares of Common Stock so purchased (the "Buy-In Price"), at which point the
                                          ------------
Company's obligation to credit such Holder's balance account with DTC for the
number of Warrant Shares to which the Holder is entitled upon the Holder's
exercise hereunder and to issue such Warrant Shares shall terminate, or (ii)
promptly honor its obligation to credit such Holder's balance account with DTC
for the number of Warrant Shares to which the Holder is entitled upon the
Holder's exercise hereunder and pay cash to the Holder in an amount equal to the
excess (if any) of the Buy-In Price over the product of (A) such number of
shares of Common Stock sold by Holder in satisfaction of its obligations, times
(B) the Closing Bid Price on the date of exercise.

1.5     EXERCISE LIMITATION.  Notwithstanding any other provision, at no time
        -------------------
may the Holder (a) exercise this Warrant such that the number of Warrant Shares
to be received pursuant to such exercise exceeds 135.0% of the aggregate of
all Tranche Purchase Prices under and in connection with all Tranche Notices
delivered pursuant to the Purchase Agreement prior to the date of exercise; or
(b) exercise this Warrant such that the number of Warrant Shares to be received
pursuant to such exercise, aggregated with all other shares of Common Stock then
owned, or deemed beneficially owned, by the Holder and its affiliates, would
result in the Holder and its affiliates owning more than 9.99% of all of such
Common Stock as would be outstanding on the date of exercise, as determined in
accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder.  In addition, as of any date, the aggregate number of
shares of Common Stock into which this Warrant is exercisable within 61 days,
together with all other shares of Common Stock then beneficially owned (as such
term is defined in Rule 13(d) under the Exchange Act) by Holder and its
affiliates, shall not exceed 9.99% of the total outstanding shares of Common
Stock as of such date.

1.6     ACTIVITY RESTRICTIONS.  For so long as Holder or any of its affiliates
        ---------------------
holds this Warrant or any Warrant Shares, neither Holder nor any affiliate will:
(i) vote any shares of Common Stock owned or controlled by it, solicit any
proxies, or seek to advise or influence any Person with respect to any voting
securities of the Company; (ii) engage or participate in any actions, plans or
proposals which relate to or would result in (a) acquiring additional securities
of the Company, alone or together with any other Person, which would result in
beneficially owning or controlling more than 9.99% of the total outstanding
Common Stock or other voting securities of the Company, (b) an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving Company or any of its subsidiaries, (c) a sale or transfer of a
material amount of assets of the Company or any of its subsidiaries, (d) any
change in the present board of directors or management of the Company, including
any plans or proposals to change the number or term of directors or to fill any
existing vacancies on the board, (e) any material change in the present
capitalization or dividend policy of the Company, (f) any other material change
in the Company's business or corporate structure, including but not limited to,
if the Company is a registered closed-end investment company, any plans or
proposals to make any changes in its investment policy for which a vote is
required by Section 13 of the Investment Company Act of 1940, (g) changes in the
Company's charter, bylaws or instruments corresponding thereto or other actions
which may impede the acquisition of control of the Company by any Person, (h)
causing a class of securities of the Company to be delisted from a national
securities exchange or to cease to be authorized to be quoted in an inter-dealer
quotation system of a registered national securities association, (i) a class of
equity securities of the Company becoming eligible for termination of
registration pursuant  to Section 12(g)(4) of the Act, or (j) any action,
intention, plan or arrangement similar to any of those enumerated above; or
(iii) request the Company or its directors, officers, employees, agents or
representatives to amend or waive any provision of this Section 1.6.
                                                        -----------

1.7     DISPUTES.  In the case of a dispute as to the determination of the
        --------
Exercise Price or the arithmetic calculation of the Warrant Shares, the Company
shall promptly issue to the Holder the number of Warrant Shares that are not
disputed and resolve such dispute in accordance with Section 12.
                                                     ----------

1.8     INSUFFICIENT AUTHORIZED SHARES.  If at any time while any portion of
        ------------------------------
this Warrant remains outstanding the Company does not have a sufficient number
of authorized and unreserved shares of Common Stock to satisfy its obligation to
reserve for issuance upon exercise of this Warrant at least a number of shares
of Common Stock equal to 110% of the number of shares of Common Stock as shall
from time to time be necessary to effect the exercise of the portion of the
Warrant then outstanding (the "Required Reserve Amount") (an "Authorized Share
                               -----------------------        ----------------
Failure"), then the Company shall immediately take all action necessary to
-------
increase the Company's authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for the portion of
the Warrant then outstanding.  Without limiting the generality of the foregoing
sentence, as soon as practicable after the date of the occurrence of an
Authorized Share Failure, but in no event later than 90 days after the
occurrence of such Authorized Share Failure, the Company shall hold a meeting of
its stockholders for the approval of an increase in the number of authorized
shares of Common Stock.  In connection with such meeting, the Company shall
provide each stockholder with a proxy statement and shall use its best efforts
to solicit its stockholders' approval of such increase in authorized shares of
Common Stock and to cause its board of directors to recommend to the
stockholders that they approve such proposal.

                                  ARTICLE 2
          ADJUSTMENT UPON SUBDIVISION OR COMBINATION OF COMMON STOCK
          ----------------------------------------------------------

     If the Company at any time on or after the Issuance Date subdivides (by any
stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common Stock into a greater number of shares, the
Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced and the number of Warrant Shares will be proportionately
increased.  If the Company at any time on or after the Issuance Date combines
(by combination, reverse stock split or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination will be proportionately
increased and the number of Warrant Shares will be proportionately decreased.
Any adjustment under this ARTICLE 2 shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                                  ARTICLE 3
                 PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS
                 -----------------------------------------

3.1     PURCHASE RIGHTS.  In addition to any adjustments pursuant to ARTICLE 2
        ---------------
above, if at any time the Company grants, issues or sells any Options,
Convertible Securities or rights to purchase stock, warrants, securities or
other property pro rata to the record holders of any class of shares of Common
Stock (the "Purchase Rights"), then the Holder will be entitled to acquire, upon
            ---------------
the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which the Holder could have acquired if the Holder had held the number of shares
of Common Stock acquirable upon complete exercise of this Warrant (without
regard to any limitations on the exercise of this Warrant) immediately before
the date on which a record is taken for the grant, issuance or sale of such
Purchase Rights, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights.

3.2     SUBSEQUENT EQUITY SALES. In addition to any adjustments made pursuant to
        -----------------------
ARTICLE 2 above, if the Company or any Subsidiary thereof, as applicable, at any
time subsequent to the first Tranche Closing Date while this Warrant is
outstanding, shall sell or grant any option to purchase, or sell or grant any
right to reprice, or otherwise dispose of or issue (or announce any offer, sale,
grant or any option to purchase or other disposition) any Common Stock or Common
Stock Equivalents entitling any Person other than the Holder to acquire shares
of Common Stock, at an effective price per share less than the then Exercise
Price (such lower price, the "Base Share Price" and such issuances,
                              ----------------
collectively, a "Dilutive Issuance"), then the Exercise Price shall be reduced
                 -----------------
and only reduced to equal the Base Share Price and the number of Warrant Shares
issuable hereunder shall be increased such that the aggregate Exercise Price
payable hereunder, after taking into account the decrease in the Exercise Price,
shall be equal to the aggregate Exercise Price prior to such adjustment.  Except
as otherwise provided herein, such adjustment shall be made whenever such Common
Stock or Common Stock Equivalents are issued.  If the holder of the Common Stock
or Common Stock Equivalents so issued shall at any time, whether by operation of
purchase price adjustments, reset provisions, floating conversion, exercise or
exchange prices or otherwise, or due to warrants, options or rights per share
which are issued in connection with such issuance, be entitled to receive shares
of Common Stock at an effective price per share which is less than the Exercise
Price, such issuance shall be deemed to have occurred for less than the Exercise
Price on such date of the Dilutive Issuance, provided, however, that such date
                                             --------  -------
of the Dilutive Issuance is after the first Tranche Closing Date.
Notwithstanding the foregoing, no adjustments shall be made, paid or issued
under this Section 3.2 in respect of an Exempt Issuance, subject to adjustment
           -----------
for reverse and forward stock splits, stock dividends, stock combinations and
other similar transactions of the Common Stock, or securities issued under
employee benefit plans, that occur after the date of the Purchase Agreement. The
Company shall notify the Holder in writing, no later than the Trading Day
following the issuance of any Common Stock or Common Stock Equivalents subject
to this Section 3.2, indicating therein the applicable issuance price, or
        -----------
applicable reset price, exchange price, conversion price and other pricing terms
(such notice the "Dilutive Issuance Notice").  For purposes of clarification,
                  ------------------------
whether or not the Company provides a Dilutive Issuance Notice pursuant to this
Section 3.2, upon the occurrence of any Dilutive Issuance, after the date of
-----------
such Dilutive Issuance the Holder is entitled to receive a number of Warrant
Shares based upon the Base Share Price regardless of whether the Holder
accurately refers to the Base Share Price in the Notice of Exercise.

3.3     FUNDAMENTAL TRANSACTIONS.  The Company shall not enter into or be party
        ------------------------
to a Fundamental Transaction unless the Successor Entity assumes in writing all
of the obligations of the Company under this Warrant in accordance with the
provisions of this Section 3.3 pursuant to written agreements in form and
                   -----------
substance satisfactory to the Required Holders and approved by the Required
Holders prior to such Fundamental Transaction, including agreements to deliver
to each Holder of this Warrant in exchange for such Warrant a security of the
Successor Entity evidenced by a written instrument substantially similar in form
and substance to this Warrant, including, without limitation, an adjusted
exercise price equal to the value for the shares of Common Stock reflected by
the terms of such Fundamental Transaction, and exercisable for a corresponding
number of shares of capital stock equivalent to the shares of Common Stock
acquirable and receivable upon exercise of this Warrant (without regard to any
limitations on the exercise of this Warrant) prior to such Fundamental
Transaction, and satisfactory to the Required Holders.  Upon the occurrence of
any Fundamental Transaction, the Successor Entity shall succeed to, and be
substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Warrant referring to the "Company" shall
refer instead to the Successor Entity), and may exercise every right and power
of the Company and shall assume all of the obligations of the Company under this
Warrant with the same effect as if such Successor Entity had been named as the
Company herein.  Upon consummation of the Fundamental Transaction, the Successor
Entity shall deliver to the Holder confirmation that there shall be issued upon
exercise of this Warrant at any time after the consummation of the Fundamental
Transaction, in lieu of the shares of the Common Stock (or other securities,
cash, assets or other property) purchasable upon the exercise of this Warrant
prior to such Fundamental Transaction, such shares of stock, securities, cash,
assets or any other property whatsoever (including warrants or other purchase or
subscription rights) which the Holder would have been entitled to receive upon
the happening of such Fundamental Transaction had this Warrant been converted
immediately prior to such Fundamental Transaction, as adjusted in accordance
with the provisions of this Warrant.  In addition to and not in substitution for
any other rights hereunder, prior to the consummation of any Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to
receive securities or other assets with respect to or in exchange for shares of
Common Stock (a "Corporate Event"), the Company shall make appropriate provision
                 ---------------
to insure that the Holder will thereafter have the right to receive upon an
exercise of this Warrant at any time after the consummation of the Fundamental
Transaction, in lieu of the shares of the Common Stock (or other securities,
cash, assets or other property) purchasable upon the exercise of this Warrant
prior to such Fundamental Transaction, such shares of stock, securities, cash,
assets or any other property whatsoever (including warrants or other purchase or
subscription rights) which the Holder would have been entitled to receive upon
the happening of such Fundamental Transaction had this Warrant been exercised
immediately prior to such Fundamental Transaction; provided, however, that in
the event the Fundamental Transaction involves the issuance of cash or freely
tradable securities by an issuer listed on the New York Stock Exchange or the
Nasdaq Stock Market, then the ability to exercise this Warrant shall expire on
the consummation of that Fundamental Transaction.  Provision made pursuant to
the preceding sentence shall be in a form and substance reasonably satisfactory
to the Required Holders.  The provisions of this Section 3.3 shall apply
                                                 -----------
similarly and equally to successive Fundamental Transactions and Corporate
Events and shall be applied without regard to any limitations on the exercise of
this Warrant.

3.4     Notwithstanding the foregoing Section 3.3, in the event of a Fundamental
                                      -----------
Transaction (other than one in which the Successor Entity is (i) The Quercus
Trust or an Affiliate thereof, or (ii) a Public Successor Entity that assumes
this Warrant such that this Warrant shall be exercisable for the publicly traded
common stock of such Public Successor Entity), at the request of the Holder
delivered before the 90th day after the effective date of such Fundamental
Transaction, the Company (or the Successor Entity) shall purchase this Warrant
from the Holder by paying to the Holder, within five (5) Trading Days after such
request (or, if later, on the effective date of the Fundamental Transaction),
cash in an amount equal to the value of the remaining unexercised portion of
this Warrant on the date of such consummation, which value shall be determined
by use of the Black Scholes Option Pricing Model using a volatility equal to the
100 day average historical price volatility prior to the date of the public
announcement of such Fundamental Transaction.

                                  ARTICLE 4
                              NONCIRCUMVENTION
                              ----------------

     The Company hereby covenants and agrees that the Company will not, by
amendment of its certificate or articles of incorporation, articles of
association, bylaws, or any other organization documents, or through any
reorganization, transfer of assets, consolidation, merger, scheme of
arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, and will at all times in good faith carry out all the
provisions of this Warrant and take all action as may be required to protect the
rights of the Holder.  Without limiting the generality of the foregoing, the
Company (i) shall not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, (ii) shall take all such actions as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant, and
(iii) shall, so long as any portion of this Warrant remains outstanding, take
all action necessary to reserve and keep available out of its authorized and
unissued shares of Common Stock, solely for the purpose of effecting the
exercise of this Warrant, 110% of the number of shares of Common Stock as shall
from time to time be necessary to effect the exercise of this Warrant then
outstanding (without regard to any limitations on exercise).

     This Warrant shall be governed by and construed and enforced in accordance
with, and all questions concerning the construction, validity, interpretation
and performance of this Warrant shall be governed by, the internal laws of the

     This Warrant shall be deemed to be jointly drafted by the Company and the
Holder and shall not be construed against any person as the drafter hereof.  The
headings of this Warrant are for convenience of reference and shall not form

                               ------------------

     In the case of a dispute as to the determination of the Exercise Price or
the arithmetic calculation of the Warrant Shares, the Company shall submit the
disputed determinations or arithmetic calculations via facsimile within 2
Trading Days of receipt of the Exercise Notice giving rise to such dispute, as
the case may be, to the Holder.  If the Holder and the Company are unable to
agree upon such determination or calculation of the Exercise Price or the
Warrant Shares within three Trading Days of such disputed determination or
arithmetic calculation being submitted to the Holder, then the Company shall,
within 2 Trading Days submit via facsimile (a) the disputed determination of the
Exercise Price or arithmetic calculation to an independent, reputable investment
bank or independent registered public accounting firm selected by Holder subject
to Company's approval, which may not be unreasonably withheld or delayed, or (b)
the disputed arithmetic calculation of the Warrant Shares to the Company's
independent registered public accounting firm.  The Company shall cause at its
expense the investment bank or the accountant, as the case may be, to perform
the determinations or calculations and notify the Company and the Holder of the
results no later than 3 Trading Days from the time it receives the disputed
determinations or calculations.  Such investment bank's or accountant's
determination or calculation, as the case may be, shall be binding upon all
parties absent demonstrable error.

            REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF
            -----------------------------------------------------------

     The remedies provided in this Warrant shall be cumulative and in addition
to all other remedies available under this Warrant, at law or in equity
(including a decree of specific performance and/or other injunctive relief), and
nothing herein shall limit the right of the Holder right to pursue actual
damages for any failure by the Company to comply with the terms of this Warrant.
The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Holder 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, the holder of this Warrant 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.
