RECITALS





A.           Maker
made and delivered its Promissory Note dated April 8, 2005 in the face amount of
$1,250,000 to Marti D. Lundy (the "Original

November 18, 2005, January 3, 2006, May 18, 2006 and
August 8, 2006.





B.           Contemporaneously
with the execution and delivery of the Original Note, Marti D. Lundy, Maker
and Co-Maker executed and delivered a Security Agreement dated April 8,
2005 (the "Security Agreement"), under which, among other things, Maker and
Co-Maker granted to Marti D. Lundy a security interest in the collateral
described in the Security Agreement.





C.           Holder
acquired from Marti D. Lundy all right, title and interest in the Original Note
and in the Security Agreement.





D.           On
or about October 19, 2006, Maker and Holder entered into an Agreement Regarding
Amendment of Promissory Note (the "First Amended
Agreement") and an Amended and Restated Promissory Note (the "First Restated Note")
in the principal amount of $1,028,982, together with warrants to purchase shares
of Maker's Common Stock.





E.           On
or about March 12, 2007, Maker, Co-Maker and Holder entered into a Second
Agreement Regarding Amendment of Promissory Note (the "Second Amended
Agreement") and a Second Amended and Restated Promissory Note in the
principal amount of $1,721,428.78 (the "Second Restated
Note"), which superseded each of the First Amended Agreement and the
First Restated Note in their entirety.  As of the date hereof, the
Second Restated Note has an outstanding balance of $477,742.96.





F.           Maker
has requested that Holder loan up to an additional $500,000, and Holder has
agreed to make such loans on the terms and conditions set forth
herein.





NOW,
THEREFORE, for valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties to this Agreement agree as
follows:





2.           Definitions.  Capitalized
terms used in this Agreement that are not defined herein have the meanings
assigned to those terms in the Third Restated Note (defined below).








3.           Third Restated
Note.  Simultaneously with the execution of this Agreement,
Maker and Co-Maker will execute and deliver to Holder a Third Amended and
Restated Promissory Note in the principal amount of $977,742.96 (the "Third Restated
Note").  Maker and Co-Maker agree that the granting, renewing,
extending or making of any advance of any loan by Holder under this Agreement
and the Third Restated Note at all times will be based upon the cash budgets of
Maker and Co-Maker as accepted by Holder in Holder's sole judgment and
discretion.  The Third Restated Note will be in substantially the form
attached hereto as Exhibit A and
will replace and supersede the Original Note, the First Restated Note and the
Second Restated Note in their entirety.  Holder will deliver the
original Second Restated Note to Maker for cancellation.  The term
"Third Restated
Note" includes all amendments, modifica­tions, replacements and
addenda thereto.

REGARDING AMENDMENT OF PROMISSORY NOTE











4.           Stock
Warrant.  As additional consideration to Holder for extending
additional credit to Maker and Co-Maker, for each $100,000 (or part thereof)
advanced to Maker and Co-Maker under the Third Restated Note, whether prior to,
on or after the date hereof, Maker will issue and deliver to Holder a warrant or
warrants in the form attached hereto as Exhibit B to purchase
1,066,667 common shares of Maker, with an exercise price of $0.001 per share
(the "New
Warrants"), up to a maximum of 10,666,670 shares if the entire
$977,742.96 is advanced under this Agreement.  The New Warrants will
have an exercise period of five years from the date of issuance.  The
New Warrants will be assignable by Holder and will permit a cashless exercise by
Holder.  Maker's Board of Directors will have approved its agreement
to issue the New Warrants as a condition of this Agreement.








5.           Registration
Rights.  Simultaneously with the execution of this Agreement,
Maker and Holder will enter into a registration rights agreement, satisfactory
to Holder and its counsel, which provides for demand and "piggy back"
registration rights with respect to common shares which may be issued pursuant
to the exercise of the New Warrants.








6.           Right of First Refusal;
Participation Rights.  Holder will have the right to
participate in any future financings, whether debt or equity, prior to and on
any merger of Maker with an operating company at the same price and under the
same terms as are detailed in any term sheet, offering memorandum or other
document evidencing the terms of the transaction.  Maker will notify
Holder within five business days of receiving any such term sheet or offering
memorandum.  The participation rights granted in this Section 5 will expire upon the occurrence of the earlier
to occur of (a) when the Third Restated Note is paid in full, or
(b) a Qualified Liquidity Event; provided however, that if the Third Restated
Note is not paid in full at such time, then the participation rights granted in
this Section 5 will continue until the Third Restated Note is paid in
full.  For purposes of this Agreement, a "Qualified Liquidity Event"
means the first to occur of a Sale Transaction or a Public
Offering.  A "Sale Transaction" means (i) the sale (in one or a
series of related transactions) of all or substantially all of Maker's assets to
a Person (defined below) or a group of Persons acting in concert, (ii) the
sale or transfer (in one or a series of related transactions) of a majority of
the outstanding capital stock of Maker, to one Person or a group of Persons
acting in concert, or (iii) the merger or consolidation of Maker with or
into another Person that is not an affiliate of Maker, in each case in clauses
(ii) and (iii) above under circumstances in which the holders of a majority in
voting power of the outstanding capital stock of Maker immediately prior to such
transaction (excluding any Person or group of Persons acting in concert who are
acquiring Maker) own less than a majority in voting power of the outstanding
capital stock of Maker, or voting equity securities of the surviving or
resulting corporation or acquirer, as the case may be, immediately following
such transaction.  A sale (or multiple related sales) of assets
including, without limitation, one or more subsidiaries (whether by way of
merger, consolidation, reorganization or sale of all or substantially all assets
or securities) which constitutes all or substantially all of the assets of Maker
shall bee deemed a Sale Transaction.  "Person" shall be
construed in the broadest sense and means and includes, without limitation, a
natural person, a partnership, a corporation, an association, a joint stock
company, a limited liability company, a trust, a joint venture, an
unincorporated organization and any other entity.  "Public Offering"
means an offering of at least $5,000,000 of equity securities of Maker or any
subsidiary (or any successor-in-interest of the foregoing) listed on a
nationally recognized exchange or quoted on the Nasdaq Stock Market that is made
pursuant to an effective registration statement under the Securities Act of
1933, as amended.

REGARDING AMENDMENT OF PROMISSORY NOTE








7.           Fees and
Expenses.  Simultaneously with execution of this Agreement,
Maker will pay Holder (a) a fully earned, nonrefundable loan fee in an
amount equal to 3.5% of the principal amount of the Third Restated Note amount,
and (b) Holder's reasonable out-of-pocket costs and expenses related to
this transaction, including reasonable attorney fees and expenses for the
documentation and negotiation of this Agreement, the Third Restated Note,
Warrant and related documents.  In the event Maker does not have
sufficient funds to pay the loan fee and Holder’s costs and expenses at the time
of execution of this Agreement, then the loan fee and costs and expenses shall
be deducted from the next advance under the Third Restated Note.








8.           Representations and
Warranties.  Maker and Co-Maker represent and warrant to
Holder, as of the date of this Agreement, and at all times the Third Restated
Note is outstanding:

and Co-Maker are, and at all times will be, duly organized and validly existing

records concerning the Collateral for the Third Restated Note.  Maker
and Co-Maker will notify Holder at least 30 days prior to any change in the
location of Maker's or Co-Maker's state of organization or any change in Maker's

and Co-Maker's execution, delivery and per­formance of this Agreement and
all of their respective agreements referred to herein, including without
limitation, the Third Restated Note and New Warrants, have been duly authorized

or agreements or instruments binding upon Maker or Co-Maker or (2) any law,
governmental regulation, court decree or order applicable to Maker, Co-Maker or
their properties.

accordance with their respective terms, subject only to the effect of
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, and
other similar laws relating to or affecting creditors' rights generally and
court decisions with respect thereto, and the award by courts of money damages
rather than specific performance of contractual provisions involving matters
other than the payment of money.





8.5.           Capitalization.  The
shares of Common Stock to be issued by Maker upon exercise of the New Warrants
will be, when issued in accordance therewith, duly authorized, validly issued,

Co-Maker's financial statements or in writing to Holder and as accepted by
Holder, and except for property tax liens for taxes not presently due and
payable, Maker and Co-Maker own and have good title to all of their properties
free and clear of all security interests, and have not executed any security
documents or financing statements relating to such properties.  All of
Maker's and Co-Maker's properties are titled in their respective legal name, and
Maker and Co-Maker have not used or filed a financing statement under any other
name for at least the last five years.

knowledge, threatened.

the best of Maker's and Co-Maker's knowledge, all of Maker's and Co-Maker's tax
returns and reports that are or were required to be filed, have been filed, and

except those presently being or to be contested by Maker or Co-Maker in good
faith in the ordinary course of business and for which adequate reserves have
been provided.





8.9.           Lien
Priority.  Unless otherwise previously disclosed to Holder in
writing (including specifically prior liens granted to Hewlett Packard Financial
Services Company), Maker and Co-Maker have not entered into or granted any
security agreements, or permitted the filing or attachment of any security
interests on or affecting any of the collateral securing repayment of the Third
Restated Note (the "Collateral"), that
would be prior or that may in any way be superior to Holder's security interests

Co-Maker, upon request of Holder, will notify such party to permit Holder free

Holder and its assigns and affiliates, Maker and Co-Maker release Holder to
disclose any financial information regarding Maker and Co-Maker, including
pro-forma financial statements, to its members, assigns, participants,
investors, officers, directors, employees and consultants ("Assigns and Agents").

Assurances.  Make, execute and deliver to Holder such
promissory notes, mortgages, deeds of trust, security agreements, assignments,

agreements as Holder or its counsel may reasonably request to evidence and
secure the Third Restated Note and to perfect all related security
interests.








10.           Holder's
Expenditures.  If any action or proceeding is commenced that
would materially affect Holder's interest in the Collateral or if Maker or
Co-Maker fails to comply with any provision of this Agreement or the Third
Restated Note or the Related Documents, including but not limited to Maker's or
Co-Maker's failure to discharge or pay when due any amounts Maker or Co-Maker is
required to discharge or pay under the Third Restated Note or any Related
Documents. Holder, on Maker's or Co-Maker's behalf, may (but will not be
obligated to) take any action that Holder deems appropriate, including but not
limited to discharging or paying all taxes, liens, security interests,
encumbrances and other claims, at any time levied or placed on any Collateral
and paying all costs for insuring, maintaining and preserving any
Collateral.  All such expenditures incurred or paid by Holder for such
purposes will then bear interest at the rate charged under the Third Restated
Note from the date incurred or paid by Holder to the day of repayment by Maker
or Co-Maker.  All such expenses will become a part of the Third
Restated Note balance and, at Holder's option, will (a) be payable on
demand; (b) be added to the balance of the Third Restated Note and be
apportioned among and be payable with any installment payments to become due
during the remaining term of the Third Restated Note; or (c) be treated as
a balloon payment which will be due and payable at the Third Restated Note's
Maturity.








11.           Negative
Covenants.  Maker and Co-Maker covenant and agree with Holder
that while the Third Restated Note is outstanding and unpaid, Maker and Co-Maker

12.           Additional
Documents.  The parties will sign and deliver such additional
docu­ments and take such further actions as may be reasonably necessary to
further effect and evidence this Agreement.





13.           Attorney
Fees.  If any party to this Agreement breaches any term of this
Agree­ment, the other party will be entitled to recover all costs and
expenses, including reasonable attorney fees, incurred to enforce the terms of
this Agreement, whether or not suit is filed, including such costs or fees as
may be awarded at trial, in arbitration, or in bankruptcy pro­ceedings, and
in any appeal of such suit or action.





14.           Successors and

19.           Execution and
Counterparts.  This Agreement may be executed by the parties in
