          1

          
            

          

        

        
          
          

        

      

      1.2           Initial

the purchase, sale and issuance of the Initial Notes shall take place at the
offices of Westerman Ball Ederer Miller & Sharfstein, LLP, legal counsel to
Agile (“WBEMS”),
170 Old Country Road, Fourth Floor, Mineola, New York 11501, simultaneous with
the execution hereof (the "Initial
Closing").  At the Initial Closing, (i) the Company will
deliver to each Investor its duly executed Initial Note to be delivered thereat

Initial Notes Purchase Price by wire transfer of the amount thereof to the
Company’s account or by such other method agreed to between the Investors and

Investors any other Securities to be delivered thereat pursuant to any other
Loan Documents, and (v) the Company shall pay to the Investors the amount of

      1.3           Subsequent
Closing.  On such date as
may be agreed to between the Company and the Investors, but not later than
February 27, 2009, the closing of the purchase, sale and issuance of Additional
Notes shall take place at the offices of WBEMS (the “Subsequent
Closing”).  At the Subsequent Closing, (i) the Company shall
deliver to each Investor its duly executed Additional Note to be delivered
thereat pursuant to Section

Additional Notes Purchase Price therefor by wire transfer of the amount thereof
to the Company’s account or by such other method agreed to between the Investors
and the Company, (ii) the Company shall cause to be delivered to the Investors
any other Securities to be delivered thereat pursuant to any other Loan
Documents and (iii) the Company shall pay to the Investors the amount of
interest payable on the Additional Notes pursuant to the terms of the Additional
Notes.  For the purpose of clarification, the Subsequent Closing shall
take place at the sole, absolute and several discretion of each Investor, it
being specifically contemplated and acknowledged that should only one Investor
choose to proceed with the Subsequent Closing, such Investor and the Company may
do so without any obligation of the other Investor to do so.

       

      1.4           Monitoring
Fees.  On the thirtieth
(30th) day
after the Subsequent Closing  and on every thirtieth (30th) day
thereafter (each, a “Monitoring
Fee Date”) for a total of six (6) consecutive thirty (30) day periods and
Monitoring Fee Dates, a calculation shall be made of the aggregate dollar volume
of Common Stock traded on the Principal Trading Market during the thirty (30)
days preceding the applicable Monitoring Fee Date (the “Calculated
Monthly Dollar Volume Traded”).  If on any such Monitoring Fee
Date, the Calculated Monthly Dollar Volume Traded was less than $75,000.00, then
the Company shall immediately pay to the Investors a monitoring fee of $7,500.00
for such Monitoring Fee Date (as between the Investors, such monitoring fee to
be divided in proportion to the aggregate amount of Notes purchased by
them).

      1.7           Beneficial

anything to the contrary contained herein, at no time shall either Investor
together with any “affiliates” of the Investor (as defined in the Exchange Act)
“beneficially own” enough shares of Common Stock to be deemed an “affiliate” of
the Company within the meaning of the Exchange Act (a “Company
Affiliate”).  Accordingly, each Investor (and its affiliates)
will not convert any portion of the Notes issued to it in violation of the
foregoing.  In addition, to the extent any shares of Common Stock
issuable or deliverable to an Investor pursuant to any Loan Document would cause
the Investor to be deemed a Company Affiliate in violation of the foregoing
sentence, the Company shall not issue or cause to be delivered such shares of
Common Stock to the Investor and the Investor shall not request the issuance or
delivery thereof; provided, however, that the
Company shall reserve out of its authorized share capital, sufficient shares of
Common Stock to permit it to issue such shares but for the foregoing provisions
of this Section 1.7 (“Reserved
Shares”).

       

      
        
          
          

        

        
          4

          
            

          

        

        
          
          

        

      

      (b)           At
such time as an Investor determines that the issuance or delivery of Reserved
Shares to it can be made without violating the first sentence of Section 1.7(a)
hereof, then the Investor may request that the Company issue and deliver such
number of Reserved Shares as the Investor determines it can so receive without
being deemed a Company Affiliate and which it so requests (an “Issuance
Request”) and the Company shall comply with such Issuance Request as soon
as possible thereafter; provided, however, that
notwithstanding the foregoing provisions of this Section 1.7, should the
Investor in its sole discretion determine that it may be deemed a Company
Affiliate prior to the issuance or delivery of the Reserved Shares, the Issuance
Request shall specify that the Reserved Shares so requested not be issued or
delivered prior to 61 days after such Issuance Request is made (and the
provisions of Section 1.7(a) shall continue to apply until the actual issuance
or delivery thereof).

       

      (c)           To
the extent that the limitation contained in this Section 1.7 applies, the
determination of whether a Note is convertible (in relation to other securities
owned by the Investor) and of which portion of a Note is convertible or that
Reserved Shares are issuable or deliverable and how many such Reserved Shares
are issuable or deliverable shall be in the sole discretion of such
Investor.  To ensure compliance with this restriction, the Investor
will be deemed to represent to the Company each time it delivers a Notice of
Conversion under a Note or an Issuance Request that such Notice of Conversion or
Issuance Request has not violated the restrictions set forth in this Section 1.7
and the Company shall have no obligation to verify or confirm the accuracy of
such determination.  For purposes of this Section 1.7, in determining
the number of outstanding shares of Common Stock, an Investor may rely on the
number of outstanding shares of Common Stock as reflected in (x) the Company’s
most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public
announcement by the Company or (z) any other notice by the Company or the
Company’s Transfer Agent setting forth the number of shares of Common Stock
outstanding.  Upon the written or oral request of an Investor, the Company
shall within two business days confirm orally and in writing to an Investor the
number of shares of Common Stock then outstanding.  In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company by such Investor or its
affiliates since the date as of which such number of outstanding shares of
Common Stock was reported.

       

      2.           Representations
and Warranties of the Company.  The Company
hereby represents and warrants to the Investors that:

       

      2.1           Organization,
Good Standing and Qualification.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Nevada and has all requisite corporate power and authority to
carry on its business as presently conducted or proposed to be
conducted.  The Company is duly qualified to transact business and is
in good standing in each jurisdiction in which the failure so to qualify would
have a Material Adverse Effect.  The Company has registered its Common
Stock and is obligated to file reports pursuant to Section 12 or Section 15(d)
of the Exchange Act.  The Common Stock is quoted on the Principal
Trading Market.  The Company has received no notice, either oral or
written, with respect to the eligibility or the continued eligibility of the
Common Stock for such quotation on the Principal Trading Market, and the Company
has maintained all requirements on its part for the continuation of such
quotation.

       

      
        
          
          

        

        
          5

          
            

          

        

        
          
          

        

      

      2.2           Capitalization.  As of immediately
prior to the Closing, the authorized capital stock of the Company consists
solely of (i) 500,000,000 shares of Common Stock, of which 230,374,275 shares
are issued and outstanding, and (ii) 25,000,000 shares of Preferred Stock, par
value $.001 per share, of which 10,000,000 shares are authorized as shares of
Series A Preferred Stock, of which 23,532,600 shares are issued and outstanding
and are convertible into an aggregate of 627,614,442 shares of Common
Stock.  All of the outstanding shares of Common Stock have been duly
authorized, are fully paid and nonassessable.  Except as set forth on
Schedule
2.2, the Beneficial Ownership Table contained in the latest periodic
filing made by the Company with the SEC under the Exchange Act, is accurate and
complete as of the date hereof.  Except as set forth on such
Beneficial Ownership table, in the preceding sentences of this Section 2.2 or on
Schedule
2.2, there are no options, warrants, subscriptions, conversion rights or
securities exchange rights or other securities or other contractual rights
outstanding which require, or give any person the right to require the issuance,
delivery or sale (including the right of conversion or exchange) of any capital
stock of the Company whether or not such rights are presently
exercisable.

       

      2.3           Authorization.  All corporate
action on the part of the Company necessary for the authorization, execution and
delivery of this Agreement, and the authorization, issuance and delivery of the
Securities has been taken and each of the Loan Documents, when executed and
delivered by the Company and assuming due execution and delivery by the
Investors, shall constitute a valid and legally binding obligation of the
Company, enforceable against the Company in accordance with its terms, except as
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance, or other laws of general application relating to or
affecting the enforcement of creditors’ rights generally, and as limited by
laws relating to the availability of specific performance, injunctive relief, or
other equitable remedies.

       

      2.4           Valid
Issuance of Securities.  The Securities
when issued, sold and delivered in accordance with the terms hereof for the
consideration expressed herein, will be duly and validly issued, fully paid and
nonassessable and free of restrictions on transfer other than restrictions on
transfer under applicable state and federal securities laws, except for Free
Trading Stock which shall be free of all restrictions on transfer under
securities laws.

       

      2.5           Consents
and Approvals.  No Approval by,
from or with and no other action in respect of, any Governmental Body or any
other Person (including any trustee or holder of any indebtedness, securities or
other obligations of the Company) is required (a) for or in connection with the
valid execution and/or delivery by the Company of or the performance by the
Company of its obligations under the Loan Documents or the consummation by the
Company of the transactions contemplated thereby, including the offer, issuance,
sale and delivery by the Company of the Securities, or (b) as a condition to the
legality, validity or enforceability as against the Company and the Subsidiaries
of the Loan Documents.

       

      2.6           Intellectual
Property.  The Company represents and warrants that it has full
right, title and interest in and to, or otherwise has the right to license its
Intellectual Property.  Schedule
2.6 identifies the Company’s material Intellectual Property. To the best
of the Company's knowledge, no claim is pending nor has the Company received
notice to the effect that its Intellectual Property infringes or will infringe
upon or conflict with the asserted rights of any other Person, and to the best
of the Company’s knowledge, there is no basis for any such claim (whether or not
pending or threatened).  Except as set forth on Schedule
2.6, there are no outstanding options, licenses, or agreements of any
kind relating to the foregoing, nor is the Company bound by or a party to any
options, licenses, or agreements of any kind with respect to its Intellectual
Property.  The Company is not obligated or under any liability
whatsoever to make any payments by way of royalties, fees or otherwise to any
owner of or licensor or other claimant to its Intellectual
Property.  No claim is pending or, to the Company's knowledge,
threatened to the effect that the Intellectual Property is invalid or
unenforceable by the Company, and there is no basis for any such claim (whether
or not pending or, to the Company's knowledge, threatened).

       

      
        
          
          

        

        
          6

          
            

          

        

        
          
          

        

      

      2.7           Subsidiaries.  The Company does
not own or control, directly or indirectly, any interest in any other company or
subsidiary and none of them is a participant in any joint venture, partnership
or similar arrangement.

       

      2.9           Disclosure.  No representation
or warranty of the Company contained in this Agreement, any certificate or
document furnished or to be furnished to the Investors at the Initial or
Subsequent Closing or the Financial Statements contains any untrue statement of
a material fact or omits to state a material fact necessary in order to make the
statement contained herein or therein not misleading in light of the
circumstances under which they were made.

       

      2.10           Rights of
Others Affecting the Transactions.  There are no
preemptive rights of any shareholder of the Company, as such, to acquire the
Notes or any shares of stock that may be issued to the Investors or its
designees in connection with any agreements between the parties
hereto.  No party other than an Investor has a currently exercisable
right of first refusal which would be applicable to any or all of the
transactions contemplated by the Loan Documents.

      


      2.11           Non-contravention.  The execution and
delivery of this Agreement and each of the other Loan Documents by the Company,
the issuance of the Securities, and the consummation by the Company of the
transactions contemplated by this Agreement and each of the other Loan Documents
do not and will not conflict with or result in a breach by the Company of any of
the terms or provisions of, or constitute a default under (i) the certificate of
incorporation or by-laws of the Company, each as currently in effect, (ii) any
indenture, mortgage, deed of trust, or other material agreement or instrument to
which the Company is a party or by which it or any of its properties or assets
are bound, including any listing agreement for the Common Stock except as herein
set forth, or (iii) to its knowledge, any existing applicable law, rule, or
regulation or any applicable decree, judgment, or order of any court, United
States federal or state regulatory body, administrative agency, or other
governmental body having jurisdiction over the Company or any of its properties
or assets, except such conflict, breach or default which would not have or
result in a Material Adverse Effect.

      


      2.12           Filings.  None of the
Company’s SEC Documents contained, at the time they were filed, any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements made therein in light of
the circumstances under which they were made, not misleading.  Except
for its Annual Report for the year ended September 30, 2008, since August 19,
2008, the Company has timely filed all requisite forms, reports and exhibits
thereto, if any, required to be filed by the Company with the SEC.

obligations under, any of the Loan Documents.  The Company is not
aware of any valid basis for any such claim that (either individually or in the
aggregate with all other such events and circumstances) could reasonably be
expected to have a Material Adverse Effect. There are no outstanding or
unsatisfied judgments, orders, decrees, writs, injunctions or stipulations to
which the Company is a party or by which it or any of its properties is bound,
that involve the transaction contemplated herein or that, alone or in the
aggregate, could reasonably be expect to have a Material Adverse
Effect.

      


      2.15           Absence
of Events of Default.  The Company is
not in default in the performance or observance of any material obligation,
agreement, covenant or condition contained in any material indenture, mortgage,
deed of trust or other material agreement to which it is a party or by which its
property is bound, and (ii) no Event of Default (or its equivalent term), as
defined in the respective agreement to which the Company is a party, and no
event which, with the giving of notice or the passage of time or both, would
become an Event of Default (or its equivalent term) (as so defined in such
agreement), has occurred and is continuing, which would have a Material Adverse
Effect.

      2.16           No
Undisclosed Liabilities or Events.  To the best of
the Company’s knowledge, the Company has no liabilities or obligations other
than those disclosed in the Loan Documents or the Company's SEC Documents or
those incurred in the ordinary course of the Company's business since the Last
Audited Date, or which individually or in the aggregate, do not or would not
have a Material Adverse Effect. No event or circumstances has occurred or exists
with respect to the Company or its properties, business, operations, condition
(financial or otherwise), or results of operations, which, under applicable law,
rule or regulation, requires public disclosure or announcement prior to the date
hereof by the Company but which has not been so publicly announced or
disclosed.  There are no proposals currently under consideration or
currently anticipated to be under consideration by the Board of Directors or the
executive officers of the Company which proposal would (x) change the articles
or certificate of incorporation or other charter document or by-laws of the
Company, each as currently in effect, with or without shareholder approval,
which change would reduce or otherwise adversely affect the rights and powers of
the shareholders of the Common Stock or (y) materially or substantially change
the business, assets or capital of the Company, including its interests in
subsidiaries.

      


      2.17           No
Integrated Offering.  Neither the
Company nor any of its Affiliates nor any Person acting on its or their behalf
has, directly or indirectly, at any time since February 12, 2008, made any offer
or sales of any security or solicited any offers to buy any security under
circumstances that would eliminate the availability of the exemption from
registration under Regulation D in connection with the offer and sale of the
Securities as contemplated hereby.

      


      2.18           Fees to
Brokers, Finders and Others.  Except as
specifically contemplated in this Agreement, the Company has taken no action
which would give rise to any claim by any Person for brokerage commission,
finder's fees or similar payments by the Investors relating to this Agreement or
the transactions contemplated hereby.  Investors shall have no
obligation with respect to any such fees or with respect to any claims made by
or on behalf of other Persons for fees of a type contemplated in this paragraph
that may be due in connection with the transactions contemplated
hereby.  The Company shall indemnify and hold harmless each Investor,
its employees, officers, directors, agents, and partners, and their respective
Affiliates, from and against all claims, losses, damages, costs (including the
costs of preparation and attorney's fees) and expenses suffered in respect of
any such claimed or existing fees, as and when incurred.

      


      2.19           Full
Disclosure.  To the best of
the Company’s knowledge, there is no fact known to the Company (other than
general economic conditions known to the public generally or as disclosed in the
Company’s SEC Documents) that has not been disclosed in writing to the Investors
that would reasonably be expected to have or result in a Material Adverse
Effect.

      


      2.20           Confirmation.  The Company
confirms that all statements of the Company contained herein shall survive
acceptance of this Agreement by the Investors.  The Company agrees
that, if any events occur or circumstances exist prior to the Subsequent Closing
Date which would make any of the Company’s representations, warranties,
agreements or other information set forth herein materially untrue or materially
inaccurate as of such date, the Company shall immediately notify the Investors
in writing prior to such date of such fact, specifying which representation,
warranty or covenant is affected and the reasons therefor.

      A breach
of any of the representations and warranties in this section, shall be deemed a
material breach of this Agreement and shall constitute an Event of Default (as
defined in the Loan Documents) and the Investors shall be entitled to exercise
all remedies available to them under the Loan Documents.

      


      3.           Representations
and Warranties of the Investors.  Each of the
Investors hereby severally represents and warrants to the Company as to itself
that:

       

      3.1           Authorization.  The Investor has
full power and authority to enter into this Agreement.  This
Agreement, when executed and delivered by the Investor, assuming due execution
and delivery by the other parties hereto, will constitute a valid and legally
binding obligation of the Investor, enforceable in accordance with its terms,
except as limited by applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance, and any other laws of general application
affecting enforcement of creditors’ rights generally, and as limited by laws
relating to the availability of a specific performance, injunctive relief, or
other equitable remedies.

       

      


      3.2           Accredited
Investor.  The Investor is
(i) an “accredited investor” as that term is defined in Rule 501 of the General
Rules and Regulations under the Securities Act, (ii) experienced in making
investments of the kind described in this Agreement and the related documents,
(iii) able, by reason of the business and financial experience of its officers
(if an entity) and professional advisors (who are not affiliated with or
compensated in any way by the Company or any of its Affiliates or selling
agents), to protect its own interests in connection with the transactions
described in this Agreement, and the related documents, and to evaluate the
merits and risks of an investment in the Securities, and (iv) able to afford the
entire loss of its investment in the Securities.

       

      3.3           Restricted
Securities.  The Investor
understands that the Notes and the Restricted Stock are “restricted securities”
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, the Investor must hold the Notes indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available.

       

      4.           Miscellaneous.

       

                 4.1           Registration
Rights.  Each time the Company proposes to register any of its
securities under the Securities Act whether for its own account or for the
account of holders of its securities or both (except with respect to
registration statements on Forms S-4, S-8 or any successor or similar form or
“Rule 145” transactions), it shall include in the registration initiated by the
Company (i) all of the shares of Restricted Stock issued to the Investors under
any Loan Documents and (ii) all shares of Common Stock into which the Notes may
be convertible or have been converted (collectively, "Registrable
Stock").  If any particular registration to be effected
pursuant to this Section
4.1 shall be, in whole or in part, an underwritten public offering of
Common Stock for the account of the Company, the number of shares of Registrable
Stock to be included in such an underwriting on behalf of the Investor may be
reduced if, and to the extent that, the managing underwriter shall be of the
opinion (a written copy of which shall be delivered to the Investor) that the
inclusion of all of the shares of Registrable Stock requested to be included in
such underwriting by the Investor would materially and adversely affect the
marketing of the Common Stock to be sold by the Company under such registration
statement.  The Company shall comply with all legal requirements to
maintain “evergreen” any registration statement that includes any Registrable
Stock for so long as any Notes are outstanding or any Registrable Stock is
outstanding that has not yet been sold thereunder.

      4.2           Use of
Proceeds.  The parties agree
that the net proceeds from the issuance of the Notes will be used as set forth
on Schedule
4.2.

      


      4.3           Certain
Agreements and Covenants.  The Company
hereby covenants with the Investors that (i) an agreement with a market
awareness firm to perform investor and public relations services for the Company
shall be entered into by the Company on or prior to February 27, 2009 and shall
remain in full force and effect until the Notes have been repaid in full, (ii)
that the Company’s cancelled Agreement and Plan of Merger with SolCool One, LLC
dated November 26, 2008 will be re-entered into by the Initial Closing Date and
closed subsequent thereto as soon as reasonably possible, (iii) that all other
items listed as “Conditions to Closing” pursuant to that certain Term Sheet
among the parties hereto and dated January 26, 2009 have been or will be
delivered to the Investors on or prior to the Subsequent Closing Date and (iv)
that the Company shall, if requested by any Investor, deliver to the Investors a
legal opinion of Company counsel, such counsel and opinion as are acceptable to
the Investors, on or prior to the Subsequent Closing, which opinion shall be
with respect to such matters as such Investor may request.

       

      4.4           Agent.

       

      (a) Authorization of
Action.  Each Investor hereby appoints and authorizes Agile
Opportunity Fund, LLC  (the “Agent”) to be its agent in its name and
on its behalf and to exercise such rights or powers granted to the Agent or the
Investors (i) under the Loan Documents to the extent specifically provided
therein and on the terms thereof, together with such rights, powers and
discretions as are reasonably incidental thereto.  As to any matters
not expressly provided for by the Loan Documents, the Agent shall not be
required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Investors, and any action
so taken or not so taken by the Agent shall be binding upon all the Investors;
provided, however, that the
Agent shall not be required to take any action which exposes the Agent to
liability in such capacity, which could result in the Agent incurring any costs
and expenses or which is contrary to this Agreement or applicable
law.

       

      (b) Indemnification.  Each
Investor hereby agrees to indemnify and hold harmless the Agent from and against
any and all liabilities, obligations, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against the Agent (in its capacity
as agent for the Investors) in any way relating to or arising out of the Loan
Documents or any action taken or admitted by the Agent under or in respect of
the Loan Documents; provided that no Investor shall be liable for any portion of
such liabilities, obligations, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Agent’s gross negligence or
willful misconduct.  Without limiting the generality of the foregoing,
each Investor agrees to reimburse the Agent promptly upon demand on a pro rata
basis in accordance with the then outstanding indebtedness, liabilities and
obligations owing to such Investor by the Company in respect of any
out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the preservation of any rights of the Agent or the Investors
under, the enforcement of, or legal advice in respect of the rights or
responsibilities under, the Loan Documents, to the extent that the Agent is not
reimbursed for such expenses by the Company.

       

      
        
          
          

        

        
          11

          
            

          

        

        
          
          

        

      

      (c) Successor
Agent.  The Agent may, as hereinafter provided, resign at any
time by giving not less than 30 days’ written notice thereof to the Investors
and the Company. Upon any such resignation, the Investors shall have the right
to appoint a successor Agent (the “Successor
Agent”).  Upon the acceptance of any appointment as Agent
hereunder by a Successor Agent, such Successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent and the retiring Agent shall thereupon be discharged from its
further duties and obligations as Agent under the Loan Documents. After any
retiring Agent’s resignation hereunder as Agent, the provisions of this Section
shall continue to inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under the Loan Documents.   Absent
such a resignation by the Agent, the Agent’s appointment shall continue until
revoked in writing by Investors holding 75% of the outstanding principal amount
of the Notes, at which time such Investors shall appoint a new
Agent.

       

      (d) Taking and Enforcement of
Remedies.  Each of the Investors hereby acknowledges that, to
the extent permitted by applicable law, the remedies provided under the Loan
Documents to the Investors are for the benefit of the Investors collectively and
acting together and not severally and further acknowledges that its rights under
the Loan Documents are to be exercised not severally, but collectively by the
Agent upon the decision of the Investors; accordingly, notwithstanding any of
the provisions contained in any of the Loan Documents, each of the Investors
hereby covenants and agrees that it shall not be entitled to take any action
with respect to the Loan Documents, including, without limitation, any
acceleration of the indebtedness, liabilities or obligations of the Company, but
that any such action shall be taken only by the Agent with the consent of the
Investors, provided that, notwithstanding the foregoing:

       

      (i)           in
the absence of instructions from the Investors, the Agent may without notice to
or consent of the Investors take such action on behalf of the Investors as it
deems appropriate or desirable in the interest of the Investors;

       

      (ii)           the
commencement of litigation before any court shall be made in the name of each
Investor individually unless the laws of the jurisdiction of such court permit
such litigation to be commenced in the name of the Agent on behalf of the
Investors (whether pursuant to a specific power of attorney in favor of the
Agent or otherwise) and the Agent agrees to commence such litigation in its
name; provided,
however, that
no litigation shall be commenced in the name of any Investor without the prior
written consent of such Investor; and

       

      
        
          
          

        

        
          12

          
            

          

        

        
          
          

        

      

      (iii)         
each of the Investors hereby further covenants and agrees that upon any such
written consent being given by the Investors, they shall co-operate fully with
the Agent to the extent requested by the Agent in the collective realization,
including, without limitation, the appointment of a receiver and manager to act
for their collective benefit; and each Investor covenants and agrees to do all
acts and things to make, execute and deliver all agreements and other
instruments, including, without limitation, any instruments necessary to effect
any registrations, so as to fully carry out the intent and purpose of this
Section; and each of the Investors hereby covenants and agrees that it has not
heretofore and shall not seek, take, accept or receive any security for any of
the obligations and liabilities of the Company under the Loan Documents or under
any other document, instrument, writing or agreement ancillary thereto other
than such security as is provided hereunder and shall not enter into any
agreement with the Company relating in any manner whatsoever to the transactions
contemplated hereunder, unless all of the Investors shall at the same time
obtain the benefit of any such security or agreement, as the case may
be.

       

      Notwithstanding
any other provision contained in the Loan Documents, no Investor shall be
required to be joined as a party to any litigation commenced against the Company
by the Agent under the Loan Documents (unless otherwise required by any court of
competent jurisdiction) if it elects not to be so joined in which event any such
litigation shall not include claims in respect of the rights of such Investor
against the Company under the Loan Documents until such time as such Investor
does elect to be so joined; provided that if at the time of such subsequent
election it is not possible or practicable for such Investor to be so joined,
then such Investor may commence proceedings in its own name in respect of its
rights against the Company.

       

      4.4           Successors
and Assigns.  This Agreement
may not be assigned by the Company without the prior written consent of the
Investors.  The terms and conditions of this Agreement shall inure to
the benefit of and be binding upon the respective successors and permitted
assigns of the parties.  Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations,
or liabilities under or by reason of this Agreement, except as expressly
provided in this Agreement.  This Agreement may be assigned by each of
the Investors without the prior consent of the Company.

whole or in part, into shares (each, a “Conversion
Share”) of Common Stock at a conversion price equal to $0.10 per Conversion Share,
subject to adjustment as provided in Section 2 herein (the “Conversion
Price”).

      


      (b)           Lender
may convert this Note at the Conversion Price by the surrender of this Note
(properly endorsed) to the Company at the principal office of the Borrower,
together with the form of Notice of Conversion attached hereto as Annex A (a
“Notice of
Conversion”) duly completed, dated and executed, specifying therein the
principal amount of this Note and/or outstanding interest to be
converted.  The “Conversion Date” shall be the date that such Notice
of Conversion and this Note is duly provided to Borrower hereunder (or, at
Lender's option, the next interest payment date with respect to Lender's
conversion of any scheduled interest payment).  In the event that the
Lender shall specify a name or names other than that of the Lender to receive
any of the Conversion Shares issuable upon such exercise of the conversion
option, the Notice of Conversion also shall be accompanied by payment of all
transfer taxes payable upon the issuance of the Conversion Shares to such
specified person(s).

      


      (c)           On
the date of receipt by the Company of the duly completed, dated and executed
Notice of Conversion, this Note and applicable transfer taxes, if any, all in
accordance with Section 1(b) with respect to a conversion of any portion of this
Note, the Lender (and any person(s) receiving Conversion Shares in lieu of the
Lender) shall be deemed to have become the holder of record for all purposes of
the Conversion Shares to which such valid conversion relates.

      


      (d)           As
soon as practicable, but not in excess of five business days, after the valid
conversion of any portion of this Note, the Company, at the Company’s expense
(including the payment by Company of any applicable issuance and similar taxes,
but excluding the transfer taxes referred to in Section 1(b)), will cause to be
issued in the name of and delivered to the Lender (and/or such other person(s)
identified in the Notice of Conversion with respect to such conversion),
certificates evidencing the number of duly authorized, validly issued, fully
paid and non-assessable Conversion Shares to which the Lender (and/or such other
person(s) identified in such Notice of Conversion, shall be entitled to receive
upon the conversion), such certificates to be in such reasonable denominations
as Lender may request when delivering the Notice of Conversion.

      


      (e)           If
less than the entire Convertible Principal Balance of this Note is being
converted, the Company shall execute and deliver to the Lender a new replacement
Note (dated as of the date hereof) evidencing a face amount which is the
percentage of the original Face Amount equal to the portion of the Convertible
Principal Balance that has not been so converted.

      Section
2.  Conversion Price
Adjustment.

      


      The
initial Conversion Price as stated above shall be subject to adjustment from
time to time and such Conversion Price as adjusted shall likewise be subject to
further adjustment, all as hereinafter set forth.

      


      (a)           If
and whenever the Company issues or sells any additional securities for
consideration equivalent to a per share price of Common Stock (the “Base
Price”) less than the Conversion Price in effect immediately prior to
such issuance or sale, then immediately upon such issuance or sale the
Conversion Price shall be reduced to a new Conversion Price equal to the Base
Price; provided, however, that this
Section 2(a) shall not be applicable to the issuance of securities to pursuant
to the Securities Purchase Agreement.

      


      (b)           If
the Borrower, at any time while this Note is outstanding, (i) shall pay a stock
dividend or otherwise make a distribution or distributions on shares of its
Common Stock or any other equity or equity equivalent securities payable in
shares of Common Stock, (ii) subdivide outstanding shares of Common Stock into a
larger number of shares, (iii) combine (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (iv)
issue by reclassification of shares of the Common Stock any shares of capital
stock of the Borrower, then the Conversion Price shall be multiplied by a
fraction of which the numerator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding before such event and of which
the denominator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding after such event. Any adjustment made
pursuant to this paragraph shall become effective immediately after the record
date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification.

      


      (c)           Whenever
the Conversion Price shall be adjusted as provided in this Section 2, the
Company shall reasonably promptly provide notice of such adjustment to the
Lender together with a written statement from an authorized officer of the
Company, showing in reasonable detail the facts requiring such adjustment and
the Conversion Price that shall be in effect after such
adjustment.  Notwithstanding the foregoing, no adjustment in the
Conversion Price shall be required unless such adjustment would require a change
of at least 1% in such Conversion Price; provided, however, that any
adjustments which by reason of this Section are not required to be made shall be
carried forward and taken into account in any subsequent
adjustment.

      


      (d)           In
case of any consolidation or merger of the Borrower with or into another entity
or the conveyance of all or substantially all of the assets of the Borrower to
another entity (collectively, an “Organic
Change”), this Note shall thereafter be convertible (to the extent such
conversion is permitted hereunder) into the number of shares of Common Stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Borrower deliverable upon conversion of this Note would have been
entitled had this Note been converted immediately prior to such Organic Change
and held until after the closing of such Organic Change; and, in any such case,
appropriate adjustment shall be made in the application of the provisions herein
set forth with respect to the rights and interest thereafter of Lender or any
subsequent holder of this Note, to the end that the provisions set forth herein
shall be thereafter applicable, as nearly as reasonably may be, in relation to
any shares of Common Stock or other property thereafter deliverable upon the
conversion of this Note.

      


      
        
          
          

        

        
          25

          
            

          

        

        
          
          

        

      

      Section
3.  Reservation of
Stock.  The Borrower covenants that it will at all times
reserve and keep available out of its authorized and unissued shares of Common
Stock solely for the purpose of issuance upon conversion of this Note as herein
provided, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Lender, not less than such number of shares of
the Common Stock as shall be issuable upon the conversion of the outstanding
Face Amount of this Note and accrued and unpaid interest
hereunder.  If at any time, the Company does not have available an
amount of authorized but unissued Common Stock or Common Stock held in treasury
necessary to satisfy any conversion of all amounts outstanding under this Note,
the Company shall call and hold a special meeting of its stockholders within 30
days of the occurrence of any shortfall in authorized shares for the purpose of
approving an increase in the number of shares of authorized Common Stock to an
amount sufficient to enable conversion all amounts outstanding under this Note,
subject in all respects to compliance with the requirements of Section 14 of the
Securities Exchange Act of 1934 to which the Borrower is subject.  The
Board of Directors of the Company shall recommend that stockholders vote in
favor of increasing the number of authorized shares of Common Stock at any such
meeting.  Each Member of the Board of Directors of the Company shall
also vote all of such Director’s voting securities of the Company in favor of
such increase in authorized shares.  The Borrower covenants that all
shares of Common Stock that may be issuable upon conversion of this Note shall,
upon issue, be duly and validly authorized, issued and fully paid and
nonassessable.  No consent of any other party and no consent, license,
approval or authorization of, or registration or declaration with, any
governmental authority, bureau or agency is required in connection with the
execution, delivery or performance by the Borrower, or the validity or
enforceability of this Note other than such as have been met or obtained. The
execution, delivery and performance of this Note and all other agreements and
instruments executed and delivered or to be executed and delivered pursuant
hereto or thereto or the securities issuable upon conversion of this will not
violate any provision of any existing law or regulation or any order or decree
of any court, regulatory body or administrative agency or the certificate of
incorporation or by-laws of the Borrower or any mortgage, indenture, contract or
other agreement to which the Borrower is a party or by which the Borrower or any
property or assets of the Borrower may be bound.

       

      Section
4.  No
Fractional Shares.  Upon a conversion hereunder, the Borrower
shall not be required to issue stock certificates representing fractions of
shares of Common Stock, and in lieu of any fractional shares which would
otherwise be issuable, the Borrower shall issue the next highest whole number of
shares of Common Stock, as the case may be.

      


      Section
5.  Redemption.

      


      (a)  Mandatory
Redemption.  If at any time while this Note shall be
outstanding, the Company shall consummate: (i) a “going-private” transaction
whereby the Common Stock shall thereafter cease to be registered under the
Exchange Act; or (ii) a Sale of the Company, then the Company shall deliver a
written notice to the Lender of the pending consummation of any transaction
described in clauses (i) or (ii) of this Section 5 (each, a "Liquidity
Event") fifteen (15) days prior thereto and shall redeem this Note in
full immediately following the closing of a Liquidity Event (the “Repayment
Date”) by paying the applicable Redemption Price.  As used
herein, "Redemption
Price" shall equal all accrued but unpaid interest outstanding under this
Note, plus one hundred percent (100%) of the then outstanding Face Amount of
this Note.  The Borrower shall deliver to the Lender the Redemption
Price on the Repayment Date in immediately available funds.  For the
purpose of clarification, (i) no portion of the Prepaid Interest shall be
refundable or otherwise returned to the Company in the event of any such
redemption and (ii) after delivery of a notice of a Liquidity Event as provided
for in this Section, the Lender shall continue to be entitled to effectuate
conversions as contemplated under this Note until such time as the redemption
under this Section is consummated.

      


      
        
          
          

        

        
          26

          
            

          

        

        
          
          

        

      

      (b)  Voluntary
Prepayment.  At any time while
this Note shall be outstanding, the Company may deliver a written notice of
prepayment to the Lender of its intention to prepay the face amount of this Note
in full, or in part, fifteen (15) days prior thereto and shall then so prepay
such portion of the Note as indicated in the notice together with all accrued
but unpaid interest outstanding thereon; provided, however, that no
portion of the Prepaid Interest shall be refundable or otherwise returned to the
Company in the event of any such prepayment.  For the purpose of
clarification, after delivery of a notice of prepayment as provided for in this
Section, the Lender shall continue to be entitled to effectuate conversions as
contemplated under this Note until such time as the prepayment under this
Section is consummated.

      


      Section
6.  Transferability.  This
Note and any of the rights granted hereunder are freely transferable by the
Lender, in its sole discretion, subject to federal and state securities law
restrictions, if any.

      


      Section
7.  Event of
Default.

      


      (a)           An
"Event of
Default", wherever used herein, means any one of the following events
(whatever the reason and whether it shall be voluntary or involuntary or
effected by operation of law or pursuant to any judgment, decree or order of any
court, or any order, rule or regulation of any administrative or governmental
body):

      


      (i)           Any
default in the payment of the principal of, interest on or other charges in
respect of this Note or any other Note as and when the same shall become due and
payable (whether the Maturity Date or by acceleration or
otherwise);

      


      (ii)           The
Borrower or any subsidiary shall fail to observe or perform any other material
covenant, agreement or warranty contained in, or otherwise commit any breach or
default of any provision of this Note or any Loan Document to which it is a
party;

      


      (iii)           The
Borrower or any subsidiary shall commence, or there shall be commenced against
the Borrower or any subsidiary, a proceeding under any applicable bankruptcy or
insolvency laws as now or hereafter in effect or any successor thereto, or the
Borrower or any subsidiary commences any other proceeding under any
reorganization, arrangement, adjustment of debt, relief of debtors, dissolution,
insolvency or liquidation or similar law of any jurisdiction whether now or
hereafter in effect relating to the Borrower or subsidiary or there is commenced
against the Borrower or subsidiary any such bankruptcy, insolvency or other
proceeding which remains undismissed for a period of 60 days; or the Borrower or
subsidiary is adjudicated insolvent or bankrupt; or any order of relief or other
order approving any such case or proceeding is entered; or the Borrower or
subsidiary suffers any appointment of any custodian, private or court appointed
receiver or the like for it or any substantial part of its property which
continues undischarged or unstayed for a period of 60 days; or the Borrower or
subsidiary makes a general assignment for the benefit of creditors; or the
Borrower or subsidiary shall fail to pay, or shall state that it is unable to
pay, or shall be unable to pay, its debts generally as they become due; or the
Borrower or subsidiary shall by any act or failure to act expressly indicate its
consent to, approval of or acquiescence in any of the foregoing; or any
corporate or other action is taken by the Borrower or subsidiary for the purpose
of effecting any of the foregoing; or

      


      
        
          
          

        

        
          27

          
            

          

        

        
          
          

        

      

                 (iv)           The
Borrower or any subsidiary shall default in any of its obligations under any
other note or any mortgage, credit agreement or other facility, indenture
agreement, factoring agreement or other instrument under which there may be
issued, or by which there may be secured or evidenced any indebtedness for
borrowed money or money due under any leasing or factoring arrangement of the
Borrower, whether such indebtedness now exists or shall hereafter be created and
such default shall result in such indebtedness becoming or being declared due
and payable prior to the date on which it would otherwise become due and
payable.

      


      (b)           Following
an Event of Default, the Interest Rate shall increase to 36% per annum
immediately following such Event of Default; provided, that the
Interest Rate shall thereafter revert back to the prior Interest Rate upon all
Events of Default being cured.  Upon the occurrence of an Event of
Default hereunder, the entire Face Amount of this Note together with any accrued
but unpaid interest shall automatically become due and payable.  The
failure of the Lender to exercise any of its rights hereunder in any particular
instance shall not constitute a waiver of the same or of any other right in that
or any subsequent instance with respect to the Lender or any subsequent
holder.  The Lender need not provide and the Borrower hereby waives
any presentment, demand, protest or other notice of any kind, and the Lender may
immediately and without expiration of any grace period enforce any and all of
its rights and remedies hereunder and all other remedies available to it under
applicable law.

      


      Section
8.  Registration
Rights.  The Lender is entitled to certain registration rights
with respect to the Common Stock issuable upon conversion of this Note as set
forth in the Securities Purchase Agreement.

9.  Notices.  Any
and all notices, requests, documents or other communications or deliveries
required or permitted to be given or delivered hereunder shall be delivered in
accordance with the notice provisions of the Securities Purchase
Agreement.

      


      Section
10.  Usury.  To
the extent it may lawfully do so, the Company hereby agrees not to insist upon
or plead or in any manner whatsoever claim, and will resist any and all efforts
to be compelled to take the benefit or advantage of, usury laws wherever
enacted, now or at any time hereafter in force, in connection with any claim,
action or proceeding that may be brought by the Lender in order to enforce any
right or remedy under any Loan Document.  Notwithstanding any
provision to the contrary contained in any Loan Document, it is expressly agreed
and provided that the total liability of the Company under the Loan Documents
for payments in the nature of interest shall not exceed the maximum lawful rate
authorized under applicable law (the “Maximum Rate”), and, without
limiting the foregoing, in no event shall any rate of interest or default
interest, or both of them, when aggregated with any other sums in the nature of
interest that the Company may be obligated to pay under the Loan Documents
exceed such Maximum Rate.  It is agreed that if the maximum contract
rate of interest allowed by law and applicable to the Loan Documents is
increased or decreased by statute or any official governmental action subsequent
to the date hereof, the new maximum contract rate of interest allowed by law
will be the Maximum Rate applicable to the Loan Documents from the effective
date forward, unless such application is precluded by applicable
law.  If under any circumstances whatsoever, interest in excess of the
Maximum Rate is paid by the Company to Lender with respect to indebtedness
evidenced by the Loan Documents, such excess shall be applied by Lender to the
unpaid principal balance of any such indebtedness or be refunded to the Company,
the manner of handling such excess to be at Lender’s election.

      Section
11.  Governing Law; Waiver of
Jury Trial.  This Note and the provisions hereof are to be
construed according to and are governed by the laws of the State of New York,
without regard to principles of conflicts of laws thereof.  Borrower
agrees that the New York State Supreme Court located in the County of New York,
State of New York shall have exclusive jurisdiction in connection with any
dispute concerning or arising out of this Note, the Loan Documents, or otherwise
relating to the parties relationship.  In any action, lawsuit or
proceeding brought to enforce or interpret the provisions of this Note, the Loan
Documents and/or arising out of or relating to any dispute between the parties,
the Lender shall be entitled to recover all of its costs and expenses relating
collection and enforcement of this Note (including without limitation,
reasonable attorney’s fees and disbursements) in addition to any other relief to
which the Lender may be entitled.

      


      THE
BORROWER HEREBY WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING, CLAIM OR
COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, ARISING OUT OF
OR IN ANY WAY RELATING TO THIS NOTE.

      


      Section 12.  Successors and
Assigns.  Subject to applicable securities laws, this Note and
the rights and obligations evidenced hereby shall inure to the benefit of and be
binding upon the successors of the Company and the successors and assigns of
Lender and be freely transferable and assignable by Lender without the consent
of the Company.

      


      Section 13.  Reimbursement of
Expenses.  The Company shall reimburse the Lender for any
reasonable legal fees and disbursements incurred by the Lender in enforcement of
or protection of any of its rights under this Note.

      


      Section 14.  Amendment.  This
Note may be modified or amended or the provisions hereof waived only with the
written consent of the Lender and the Company.

      


      
        
          
          

        

        
          29

          
            

          

        

        
          
          

        

      

      Section 15.  Severability.  Wherever
possible, each provision of this Note shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Note
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Note.

                 The
undersigned Lender hereby elects to convert $__________ principal (equal to
$______ Face Amount less, if Conversion Date is prior to Maturity Date, $____
unamortized OID Amount, capitalized terms used as defined in the Note) and
$_____ interest currently outstanding and owed under the Original Issue Discount
Term Secured Convertible Promissory Note issued to Agile Opportunity Fund, LLC at

the principal sum of [Two Hundred Sixty Two Thousand Five Hundred and 00/100

($525,000.00)] (the "Face

                 Section
1.  Conversion.

      


      (a)           At
any time from the original issue date hereof through the date that this Note is
paid in full, Lender shall have the right, in its sole discretion, to convert
the then outstanding Face Amount of this Note less the then as yet unamortized
portion of the OID Amount (the “Convertible
Principal Balance”) plus accrued but unpaid interest under this Note, in
whole or in part, into shares (each, a “Conversion
Share”) of Common Stock at a conversion price equal to $0.10 per Conversion Share,
subject to adjustment as provided in Section 2 herein (the “Conversion
Price”).

      


      (b)           Lender
may convert this Note at the Conversion Price by the surrender of this Note
(properly endorsed) to the Company at the principal office of the Borrower,
together with the form of Notice of Conversion attached hereto as Annex A (a
“Notice of
Conversion”) duly completed, dated and executed, specifying therein the
principal amount of this Note and/or outstanding interest to be
converted.  The “Conversion Date” shall be the date that such Notice
of Conversion and this Note is duly provided to Borrower hereunder (or, at
Lender's option, the next interest payment date with respect to Lender's
conversion of any scheduled interest payment).  In the event that the
Lender shall specify a name or names other than that of the Lender to receive
any of the Conversion Shares issuable upon such exercise of the conversion
option, the Notice of Conversion also shall be accompanied by payment of all
transfer taxes payable upon the issuance of the Conversion Shares to such
specified person(s).

      


      (c)           On
the date of receipt by the Company of the duly completed, dated and executed
Notice of Conversion, this Note and applicable transfer taxes, if any, all in
accordance with Section 1(b) with respect to a conversion of any portion of this
Note, the Lender (and any person(s) receiving Conversion Shares in lieu of the
Lender) shall be deemed to have become the holder of record for all purposes of
the Conversion Shares to which such valid conversion relates.

      


      (d)           As
soon as practicable, but not in excess of five business days, after the valid
conversion of any portion of this Note, the Company, at the Company’s expense
(including the payment by Company of any applicable issuance and similar taxes,
but excluding the transfer taxes referred to in Section 1(b)), will cause to be
issued in the name of and delivered to the Lender (and/or such other person(s)
identified in the Notice of Conversion with respect to such conversion),
certificates evidencing the number of duly authorized, validly issued, fully
paid and non-assessable Conversion Shares to which the Lender (and/or such other
person(s) identified in such Notice of Conversion, shall be entitled to receive
upon the conversion), such certificates to be in such reasonable denominations
as Lender may request when delivering the Notice of Conversion.

      (e)           If
less than the entire Convertible Principal Balance of this Note is being
converted, the Company shall execute and deliver to the Lender a new replacement
Note (dated as of the date hereof) evidencing a face amount which is the
percentage of the original Face Amount equal to the portion of the Convertible
Principal Balance that has not been so converted.

      


      Section
2.  Conversion Price
Adjustment.

      


      The
initial Conversion Price as stated above shall be subject to adjustment from
time to time and such Conversion Price as adjusted shall likewise be subject to
further adjustment, all as hereinafter set forth.

      


      (a)           If
and whenever the Company issues or sells any additional securities for
consideration equivalent to a per share price of Common Stock (the “Base
Price”) less than the Conversion Price in effect immediately prior to
such issuance or sale, then immediately upon such issuance or sale the
Conversion Price shall be reduced to a new Conversion Price equal to the Base
Price; provided, however, that this
Section 2(a) shall not be applicable to the issuance of securities to pursuant
to the Securities Purchase Agreement.

      


      (b)           If
the Borrower, at any time while this Note is outstanding, (i) shall pay a stock
dividend or otherwise make a distribution or distributions on shares of its
Common Stock or any other equity or equity equivalent securities payable in
shares of Common Stock, (ii) subdivide outstanding shares of Common Stock into a
larger number of shares, (iii) combine (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (iv)
issue by reclassification of shares of the Common Stock any shares of capital
stock of the Borrower, then the Conversion Price shall be multiplied by a
fraction of which the numerator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding before such event and of which
the denominator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding after such event. Any adjustment made
pursuant to this paragraph shall become effective immediately after the record
date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification.

      


      (c)           Whenever
the Conversion Price shall be adjusted as provided in this Section 2, the
Company shall reasonably promptly provide notice of such adjustment to the
Lender together with a written statement from an authorized officer of the
Company, showing in reasonable detail the facts requiring such adjustment and
the Conversion Price that shall be in effect after such
adjustment.  Notwithstanding the foregoing, no adjustment in the
Conversion Price shall be required unless such adjustment would require a change
of at least 1% in such Conversion Price; provided, however, that any
adjustments which by reason of this Section are not required to be made shall be
carried forward and taken into account in any subsequent
adjustment.

      


                            (d)           In
case of any consolidation or merger of the Borrower with or into another entity
or the conveyance of all or substantially all of the assets of the Borrower to
another entity (collectively, an “Organic
Change”), this Note shall thereafter be convertible (to the extent such
conversion is permitted hereunder) into the number of shares of Common Stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Borrower deliverable upon conversion of this Note would have been
entitled had this Note been converted immediately prior to such Organic Change
and held until after the closing of such Organic Change; and, in any such case,
appropriate adjustment shall be made in the application of the provisions herein
set forth with respect to the rights and interest thereafter of Lender or any
subsequent holder of this Note, to the end that the provisions set forth herein
shall be thereafter applicable, as nearly as reasonably may be, in relation to
any shares of Common Stock or other property thereafter deliverable upon the
conversion of this Note.

      


      
        
          
          

        

        
          34

          
            

          

        

        
          
          

        

      

      Section
3.  Reservation of
Stock.  The Borrower covenants that it will at all times
reserve and keep available out of its authorized and unissued shares of Common
Stock solely for the purpose of issuance upon conversion of this Note as herein
provided, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Lender, not less than such number of shares of
the Common Stock as shall be issuable upon the conversion of the outstanding
Face Amount of this Note and accrued and unpaid interest
hereunder.  If at any time, the Company does not have available an
amount of authorized but unissued Common Stock or Common Stock held in treasury
necessary to satisfy any conversion of all amounts outstanding under this Note,
the Company shall call and hold a special meeting of its stockholders within 30
days of the occurrence of any shortfall in authorized shares for the purpose of
approving an increase in the number of shares of authorized Common Stock to an
amount sufficient to enable conversion all amounts outstanding under this Note,
subject in all respects to compliance with the requirements of Section 14 of the
Securities Exchange Act of 1934 to which the Borrower is subject.  The
Board of Directors of the Company shall recommend that stockholders vote in
favor of increasing the number of authorized shares of Common Stock at any such
meeting.  Each Member of the Board of Directors of the Company shall
also vote all of such Director’s voting securities of the Company in favor of
such increase in authorized shares.  The Borrower covenants that all
shares of Common Stock that may be issuable upon conversion of this Note shall,
upon issue, be duly and validly authorized, issued and fully paid and
nonassessable.  No consent of any other party and no consent, license,
approval or authorization of, or registration or declaration with, any
governmental authority, bureau or agency is required in connection with the
execution, delivery or performance by the Borrower, or the validity or
enforceability of this Note other than such as have been met or obtained. The
execution, delivery and performance of this Note and all other agreements and
instruments executed and delivered or to be executed and delivered pursuant
hereto or thereto or the securities issuable upon conversion of this will not
violate any provision of any existing law or regulation or any order or decree
of any court, regulatory body or administrative agency or the certificate of
incorporation or by-laws of the Borrower or any mortgage, indenture, contract or
other agreement to which the Borrower is a party or by which the Borrower or any
property or assets of the Borrower may be bound.

      


      Section
4.  No
Fractional Shares.  Upon a conversion hereunder, the Borrower
shall not be required to issue stock certificates representing fractions of
shares of Common Stock, and in lieu of any fractional shares which would
otherwise be issuable, the Borrower shall issue the next highest whole number of
shares of Common Stock, as the case may be.

      


      Section
5.  Redemption.

      


      (a)  Mandatory
Redemption.  If at any time while this Note shall be
outstanding, the Company shall consummate: (i) a “going-private” transaction
whereby the Common Stock shall thereafter cease to be registered under the
Exchange Act; or (ii) a Sale of the Company, then the Company shall deliver a
written notice to the Lender of the pending consummation of any transaction
described in clauses (i) or (ii) of this Section 5 (each, a "Liquidity
Event") fifteen (15) days prior thereto and shall redeem this Note in
full immediately following the closing of a Liquidity Event (the “Repayment
Date”) by paying the applicable Redemption Price.  As used
herein, "Redemption
Price" shall equal all accrued but unpaid interest outstanding under this
Note, plus one hundred percent (100%) of the then outstanding Face Amount of
this Note.  The Borrower shall deliver to the Lender the Redemption
Price on the Repayment Date in immediately available funds.  For the
purpose of clarification, (i) no portion of the Prepaid Interest shall be
refundable or otherwise returned to the Company in the event of any such
redemption and (ii) after delivery of a notice of a Liquidity Event as provided
for in this Section, the Lender shall continue to be entitled to effectuate
conversions as contemplated under this Note until such time as the redemption
under this Section is consummated.

      


      
        
          
          

        

        
          35

          
            

          

        

        
          
          

        

      

      (b)  Voluntary
Prepayment.  At any time while
this Note shall be outstanding, the Company may deliver a written notice of
prepayment to the Lender of its intention to prepay the face amount of this Note
in full, or in part, fifteen (15) days prior thereto and shall then so prepay
such portion of the Note as indicated in the notice together with all accrued
but unpaid interest outstanding thereon; provided, however, that no
portion of the Prepaid Interest shall be refundable or otherwise returned to the
Company in the event of any such prepayment.  For the purpose of
clarification, after delivery of a notice of prepayment as provided for in this
Section, the Lender shall continue to be entitled to effectuate conversions as
contemplated under this Note until such time as the prepayment under this
Section is consummated.

      


      Section
6.  Transferability.  This
Note and any of the rights granted hereunder are freely transferable by the
Lender, in its sole discretion, subject to federal and state securities law
restrictions, if any.

      


      Section
7.  Event of
Default.

      


      (a)           An
"Event of
Default", wherever used herein, means any one of the following events
(whatever the reason and whether it shall be voluntary or involuntary or
effected by operation of law or pursuant to any judgment, decree or order of any
court, or any order, rule or regulation of any administrative or governmental
body):

      


      (i)           Any
default in the payment of the principal of, interest on or other charges in
respect of this Note or any other Note as and when the same shall become due and
payable (whether the Maturity Date or by acceleration or
otherwise);

      


      (ii)           The
Borrower or any subsidiary shall fail to observe or perform any other material
covenant, agreement or warranty contained in, or otherwise commit any breach or
default of any provision of this Note or any Loan Document to which it is a
party;

      


      (iii)           The
Borrower or any subsidiary shall commence, or there shall be commenced against
the Borrower or any subsidiary, a proceeding under any applicable bankruptcy or
insolvency laws as now or hereafter in effect or any successor thereto, or the
Borrower or any subsidiary commences any other proceeding under any
reorganization, arrangement, adjustment of debt, relief of debtors, dissolution,
insolvency or liquidation or similar law of any jurisdiction whether now or
hereafter in effect relating to the Borrower or subsidiary or there is commenced
against the Borrower or subsidiary any such bankruptcy, insolvency or other
proceeding which remains undismissed for a period of 60 days; or the Borrower or
subsidiary is adjudicated insolvent or bankrupt; or any order of relief or other
order approving any such case or proceeding is entered; or the Borrower or
subsidiary suffers any appointment of any custodian, private or court appointed
receiver or the like for it or any substantial part of its property which
continues undischarged or unstayed for a period of 60 days; or the Borrower or
subsidiary makes a general assignment for the benefit of creditors; or the
Borrower or subsidiary shall fail to pay, or shall state that it is unable to
pay, or shall be unable to pay, its debts generally as they become due; or the
Borrower or subsidiary shall by any act or failure to act expressly indicate its
consent to, approval of or acquiescence in any of the foregoing; or any
corporate or other action is taken by the Borrower or subsidiary for the purpose
of effecting any of the foregoing; or

      


      
        
          
          

        

        
          36

          
            

          

        

        
          
          

        

      

      (iv)         The
Borrower or any subsidiary shall default in any of its obligations under any
other note or any mortgage, credit agreement or other facility, indenture
agreement, factoring agreement or other instrument under which there may be
issued, or by which there may be secured or evidenced any indebtedness for
borrowed money or money due under any leasing or factoring arrangement of the
Borrower, whether such indebtedness now exists or shall hereafter be created and
such default shall result in such indebtedness becoming or being declared due
and payable prior to the date on which it would otherwise become due and
payable.

      


      (b)           Following
an Event of Default, the Interest Rate shall increase to 36% per annum
immediately following such Event of Default; provided, that the
Interest Rate shall thereafter revert back to the prior Interest Rate upon all
Events of Default being cured.  Upon the occurrence of an Event of
Default hereunder, the entire Face Amount of this Note together with any accrued
but unpaid interest shall automatically become due and payable.  The
failure of the Lender to exercise any of its rights hereunder in any particular
instance shall not constitute a waiver of the same or of any other right in that
or any subsequent instance with respect to the Lender or any subsequent
holder.  The Lender need not provide and the Borrower hereby waives
any presentment, demand, protest or other notice of any kind, and the Lender may
immediately and without expiration of any grace period enforce any and all of
its rights and remedies hereunder and all other remedies available to it under
applicable law.

      


      Section
8.  Registration
Rights.  The Lender is entitled to certain registration rights
with respect to the Common Stock issuable upon conversion of this Note as set
forth in the Securities Purchase Agreement.

      


      Section
9.  Notices.  Any
and all notices, requests, documents or other communications or deliveries
required or permitted to be given or delivered hereunder shall be delivered in
accordance with the notice provisions of the Securities Purchase
Agreement.

      


      Section
10.  Usury.  To
the extent it may lawfully do so, the Company hereby agrees not to insist upon
or plead or in any manner whatsoever claim, and will resist any and all efforts
to be compelled to take the benefit or advantage of, usury laws wherever
enacted, now or at any time hereafter in force, in connection with any claim,
action or proceeding that may be brought by the Lender in order to enforce any
right or remedy under any Loan Document.  Notwithstanding any
provision to the contrary contained in any Loan Document, it is expressly agreed
and provided that the total liability of the Company under the Loan Documents
for payments in the nature of interest shall not exceed the maximum lawful rate
authorized under applicable law (the “Maximum Rate”), and, without
limiting the foregoing, in no event shall any rate of interest or default
interest, or both of them, when aggregated with any other sums in the nature of
interest that the Company may be obligated to pay under the Loan Documents
exceed such Maximum Rate.  It is agreed that if the maximum contract
rate of interest allowed by law and applicable to the Loan Documents is
increased or decreased by statute or any official governmental action subsequent
to the date hereof, the new maximum contract rate of interest allowed by law
will be the Maximum Rate applicable to the Loan Documents from the effective
date forward, unless such application is precluded by applicable
law.  If under any circumstances whatsoever, interest in excess of the
Maximum Rate is paid by the Company to Lender with respect to indebtedness
evidenced by the Loan Documents, such excess shall be applied by Lender to the
unpaid principal balance of any such indebtedness or be refunded to the Company,
the manner of handling such excess to be at Lender’s election.

                 Section
11.  Governing Law; Waiver of
Jury Trial.  This Note and the provisions hereof are to be
construed according to and are governed by the laws of the State of New York,
without regard to principles of conflicts of laws thereof.  Borrower
agrees that the New York State Supreme Court located in the County of New York,
State of New York shall have exclusive jurisdiction in connection with any
dispute concerning or arising out of this Note, the Loan Documents, or otherwise
relating to the parties relationship.  In any action, lawsuit or
proceeding brought to enforce or interpret the provisions of this Note, the Loan
Documents and/or arising out of or relating to any dispute between the parties,
the Lender shall be entitled to recover all of its costs and expenses relating
collection and enforcement of this Note (including without limitation,
reasonable attorney’s fees and disbursements) in addition to any other relief to
which the Lender may be entitled.

      


      THE
BORROWER HEREBY WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING, CLAIM OR
COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, ARISING OUT OF
OR IN ANY WAY RELATING TO THIS NOTE.

      


      Section 12.  Successors and
Assigns.  Subject to applicable securities laws, this Note and
the rights and obligations evidenced hereby shall inure to the benefit of and be
binding upon the successors of the Company and the successors and assigns of
Lender and be freely transferable and assignable by Lender without the consent
of the Company.

      


      Section 13.  Reimbursement of
Expenses.  The Company shall reimburse the Lender for any
reasonable legal fees and disbursements incurred by the Lender in enforcement of
or protection of any of its rights under this Note.

      


      Section 14.  Amendment.  This
Note may be modified or amended or the provisions hereof waived only with the
written consent of the Lender and the Company.

      


      
        
          
          

        

        
          38

          
            

          

        

        
          
          

        

      

      Section 15.  Severability.  Wherever
possible, each provision of this Note shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Note
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Note.

Secured Parties may declare all obligations secured hereby immediately due and
payable and may exercise the remedies of a secured party under the Uniform
Commercial Code.  Without limiting the foregoing, the Secured Parties
may require the Debtor to assemble the Collateral and make it available to the
Secured Parties at a place to be designated by the Secured Parties which is
reasonably convenient to both parties or to execute appropriate documents of
assignment, transfer and conveyance, in each case, in order to permit the
Secured Parties to take possession of and title to the
Collateral.  Unless the Collateral is perishable or threatens to
decline rapidly in value or is of a type customarily sold on a recognized
market, the Secured Parties will give the Debtor reasonable notice of the time
and place of any public sale thereof or of the time after which any private sale
or any other intended disposition thereof is to be made.  The
requirements of reasonable notice shall be met if such notice is mailed to the
Debtor via registered or certified mail, postage prepaid, at least fifteen (15)
days before the time of sale or disposition.  Expenses of retaking,
holding, preparing for sale, selling or the like, shall include the Secured
Parties’ reasonable attorneys’ fees and legal expenses.

      For good and valuable consideration,

and interest in, to and under the following (all of the following items or types
of property being herein collectively referred to as the “Patent

arising:

       

      
        
          
          

        

        
          51

          
            

          

        

        
          
          

        

      

       

      
        	
                 
      

              	
                (i)

              	
                each
      patent owned and patent application (including all reissues, divisions,
      continuations, continuation-in-part, extensions and reexaminations
      thereof) registered or applied for in the United States and all other
      nations throughout the world by the Debtor, including, without limitation,
      each patent and patent application referred to in Schedule I hereto (each,
      a “Patent”);

              


      

       

      
        	
                 
      

              	
                (ii)

              	
                each
      patent license to which the Debtor is a party, including, without
      limitation, each patent license identified in Schedule II hereto (each, a
      “Patent
      License”); and

              


      

       

      
        	
                 
      

              	
                (iii)

              	
                all
      proceeds of and revenues from the foregoing, including, without
      limitation, all proceeds of and revenues from any claim by the Debtor
      against third parties for past, present or future infringement of any
      Patent owned by the Debtor and all rights and benefits of the Debtor under
      any Patent License.

              


      

       

      The
Debtor irrevocably constitutes and appoints the Grantees and any officer or
agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full power and authority in the name of the Debtor or in
any Grantee’s name, from time to time, in any Grantee’s discretion, so long as
any Event of Default (as defined in the Notes) shall have occurred and be
continuing, to take with respect to the Patent Collateral any and all
appropriate action which the Debtor might take with respect to the Patent
Collateral and to execute any and all documents and instruments which may be
necessary or desirable to carry out the terms of this Patent Security Agreement
and to accomplish the purposes hereof.

       

      Except in the ordinary course of
business or to the extent expressly permitted in the Security Agreement or the
Notes, the Debtor agrees not to sell, license, exchange, assign or otherwise
transfer or dispose of, or grant any rights with respect to, or mortgage or
otherwise encumber, any of the Patent Collateral.

      


      The foregoing security interest is
granted in conjunction with the security interests granted by the Debtor to the
Grantees pursuant to the Security Agreement.  The Debtor acknowledges
and affirms that the rights and remedies of the Grantees with respect to the
security interest in the Patent Collateral granted hereby are more fully set
forth in the Security Agreement, the terms and provisions of which are
incorporated by reference herein as if fully set forth herein.

      


      Each
Grantee hereby agrees that the security interest granted to each Grantee hereby
secures the Obligations (as identified in the Security Agreement) and that the
claim of each such Grantee in the Patent Collateral shall rank pari passu with respect to
that of each other Grantee, and that any payment or distribution made to the
Grantees upon or with respect to their respective security interests in the
Patent Collateral shall be made pro rata in accordance with the then outstanding
principal amounts of the Notes purchased by each such Grantee.

      


      This security interest shall terminate
upon the repayment in full of the Notes or conversion thereof upon which the
Grantees shall cooperate in the filing of the necessary or appropriate documents
and instruments to release the security interest created hereby and will execute
and deliver any and all documents and/or instruments reasonably requested by
Debtor in connection therewith.

      IN WITNESS WHEREOF, the Debtor has
caused this Patent Security Agreement to be duly executed by its officer
thereunto duly authorized as of the  12th  day of February,
