with the Secretary of State of Delaware) have been duly authorized by all
necessary corporate action on the part of the Company, and no further consent or
action is required by the Company, its Board of Directors or its stockholders.
This Agreement has been duly executed by officers of the Company and constitutes
the valid and binding obligation of the Company enforceable against the Company
in accordance with its terms.

          (c) The execution, delivery and performance of this Agreement by the
Company and the consummation by the Company of the transactions contemplated
hereby do not and will not (i) conflict with or violate any provision of the
Company's certificate of incorporation or bylaws, or (ii) conflict with, or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation (with or without notice, lapse of time
or both) of, any agreement, credit facility, debt or other instrument

restriction. At such time as the Securities may be converted into the
appropriate number of shares of common stock of the Company (the "Common
Shares"), such Common Shares will be duly and validly issued, fully paid and
non-assessable, free and clear of any lien, charge, claim, security interest,
encumbrance, right of first refusal or other restriction.

          (f) As of the date hereof, all of the outstanding shares of common
stock of the Company are duly authorized, validly issued, fully paid and
non-assessable and have been issued in compliance with all applicable securities

the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including
pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date
hereof (the foregoing filings being collectively referred to herein as the "SEC

material respects with the requirements of the Securities Act of 1933, as
amended (the Securities Act") and the Exchange Act and the rules and regulations
of the Securities and Exchange Commission (the "Commission") promulgated
thereunder, and none of the SEC Reports, when filed, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Reports comply in all material
respects with applicable accounting requirements and the rules and regulations
of the Commission with respect thereto as in effect at the time of filing. Such
financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved,
except as may be otherwise specified in such financial statements or the notes
thereto, and fairly present in all material respects the financial position of
the Company as of and for the dates thereof and the results of operations and
cash flows for the periods then ended.

of which 8,000,000 have been designated Series C Convertible Preferred Stock.,

and outstanding Corporation Shares have been validly issued, are fully paid and
are non-assessable. All Corporation Shares have been issued in compliance with
all applicable federal and state securities laws.

          (j) Since December 31, 2005, there has not been any material adverse
change in the business, operations, financial condition or prospects of the
Company, except as has been publicly disclosed in SEC Reports or press releases
and it being understood that the Company needs additional financing to continue
as a "going concern."

represents and warrants to the Company as follows:


                                       5
<PAGE>

          (a) Such Purchaser, if not a natural person, is duly organized,
validly existing and in good standing, under the laws of its state of formation.
Such Purchaser, if not a natural person, has full power and authority to enter
into and perform this Agreement. The execution and delivery by such Purchaser of
this Agreement and the performance by such Purchaser of its obligations
hereunder, in each case if such Purchaser is not a natural person, have been
duly authorized and approved by all requisite company action.

          (b) This Agreement has been duly executed and delivered by such
Purchaser or duly authorized representatives of such Purchaser and constitutes
the valid and binding obligation of such Purchaser enforceable against such
Purchaser in accordance with its terms.

          (c) No consent, authorization, order or approval of, or filing or
registration with, any governmental commission, board or other regulatory body
of the United States or any state or political subdivision thereof is required
for or in connection with the consummation by such Purchaser of the transaction
contemplated hereby.

          (d) Neither the execution and delivery of this Agreement by such
Purchaser, nor the consummation by such Purchaser of the transaction
contemplated hereby, will conflict with or result in a breach of any of the
terms, conditions or provisions of its charter documents or operating agreement,
or of any statute or administrative regulation, or of any order, writ,
injunction, judgment or decree of any court or governmental authority or of any
arbitration award.

          (e) Such Purchaser is not a party to any written or oral contract,
agreement, indenture, debenture, note, commitment or other instrument under the
terms of which performance by such Purchaser according to the terms of this
Agreement will be a default or an event of acceleration, or grounds for
termination, or whereby timely performance by such Purchaser according to the
terms of this Agreement may be prohibited, prevented or delayed.

          (f) Such Purchaser has not dealt with any person or entity which is or
may be entitled to a broker's commission, finder's fee, investment banker's fee
or similar payment for arranging the transaction contemplated hereby or
introducing the parties to each other.

          (g) Such Purchaser is acquiring the Securities (and upon exercise of
the Securities, the Common Shares) for such Purchaser's own accounts and not
with a present view to or for sale in connection with any distribution of all or
any part of the Securities or the Common Shares. Such Purchaser understands that
such parties can not, directly or indirectly, transfer, offer, sell, pledge,
hypothecate or otherwise dispose of all or any part of the Securities or the
Common Shares or its or his interest in the Securities or the Common Shares (or
solicit any offers to buy, purchase or otherwise acquire to take a pledge of all
or any part thereof) except (i) as provided in Section 3 hereof or (ii) in a
manner that does not violate the registration or any other applicable provisions
of the Securities Act (or any other applicable federal securities laws) or any
applicable state securities laws; provided that in the case of a transfer under
clause (ii) hereof, the transferee of the Securities or the Common Shares from
such Purchaser must acknowledge and agree to abide by the provisions of this
Section 2.2(g) and must present to the Company or its counsel (A) a written
opinion in form and substance of legal counsel experienced in securities law
matters satisfactory to the Company indicating that the proposed transfer will
not be in violation of any of the registration provisions of the Securities Act
and the qualification provisions of applicable state securities laws or similar
successor laws, and the rules and regulations promulgated thereunder, or (B)
evidence satisfactory to the Company of full compliance with the provisions of
Rule 144 under the Securities Act or other available exemptions under the
Securities Act.


                                       6
<PAGE>

          (h) Such Purchaser has been furnished with, and hereby acknowledges
receipt of, such information as it deems necessary to evaluate its or his
investment in the Securities and understands the risks of, and other
considerations relating to, ownership of the Securities. Such Purchaser has
extensive knowledge and experience in financial affairs so that such Purchaser
is capable of evaluating the merits and risks of an investment in the Securities
and has the capacity to protect its or his own interests in connection with
purchase of the Securities. Such Purchaser's financial situation is such that it
can afford to bear the economic risk of holding the Securities for an indefinite
period of time and can afford to suffer the complete loss of its investment in
the Securities.


      3. Registration Covenant of the Company

      The Company covenants and agrees with each Purchaser as follows:

          (a) If at any time either Purchaser requests that the Company file a
registration statement for a secondary public offering of all or any portion of
the Common Shares, the Company will file, within sixty (60) business days of
receipt of such Purchaser's request, a registration statement with the
Commission which complies in all material respects with the requirements of the
Securities Act seeking the public sale of the number of Common Shares specified
in such notice. The Company will pay all reasonable expenses incurred in
connection with any registration, qualification and compliance requested
hereunder (excluding underwriting discounts and commissions), including, without
limitation, all filing, registration and qualification, printing and accounting
fees and the fees and disbursements of counsel for the Company. The Company
shall notify each Purchaser in writing at least fifteen (15) days prior to the
filing of any registration statement under the Securities Act for purposes of a
public offering of securities and will afford each Purchaser an opportunity to
include in such registration statement all or part of any Common Shares held by
such Purchaser. Each Purchaser desiring to include in any such registration
statement all or any part of his or its Common Shares, shall, within fifteen
(15) days after the above-described notice from the Company, so notify the
Company in writing. If a Purchaser decides not to include all of its Common
Shares in any registration statement thereafter filed by the Company, such
Purchaser shall nevertheless continue to have the right to include any Common
Shares in any subsequent registration statement as may be filed by the Company
with respect to offerings of its securities, all upon the terms and conditions
set forth herein.


                                       7
<PAGE>

          (b) The Company will use its diligent best efforts (i) to cause such
registration statement to become effective and (ii) to cause such registration
statement to remain effective until the completion of the proposed offering and
(iii) to prepare and file with the Commission such amendments and supplements to
the registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the sale or other disposition of all the Common
Shares covered by such registration statement, including, without limitation,
such amendments and supplements as may be necessary to reflect the intended
method of disposition from time to time of the holder.

          (c) The Company will furnish to each holder of Common Shares covered
by such registration statement such numbers of copies of such registration
statement, any amendments thereto, any documents incorporated by reference
therein, the prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the sale or other disposition of the
Common Shares.

          (d) The Company will use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
blue sky laws of such jurisdictions as shall be reasonably requested by each
holder of Common Shares covered by such registration statement and do any and
all other acts and things that may be necessary under such securities and blue
sky laws to enable each holder to consummate the sale or other disposition of
the Common Shares owned by it; provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such state or
jurisdiction and except as may be required by the Securities Act.

          (e) Within a reasonable time before each filing of the registration
statement or prospectus or amendments or supplements thereto with the SEC, the
Company will furnish counsel selected by any holder of the Common Shares copies
of such documents proposed to be filed, which counsel shall have a reasonable
opportunity to review and comment thereon.

          (f) The Company will promptly notify each holder of Common Shares
covered by the registration statement of the happening of any event which makes
any statement made in the registration statement or related prospectus untrue or
which requires the making of any changes in such registration statement or
prospectus so that they will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein in the light of the circumstances under which they
were made not misleading; and, as promptly as practicable thereafter, prepare
and file with the Commission and furnish a supplement or amendment to such
prospectus so that, as thereafter deliverable to the purchasers of such Common
Shares, such prospectus will not contain any untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

          (g) The Company will use its best efforts to prevent the issuance of
any order suspending the effectiveness of the registration statement and, if one
is issued, shall use its best efforts to obtain the withdrawal of any order
suspending the effectiveness of the registration statement at the earliest
possible moment.


                                       8
<PAGE>

          (h) If the registration statement under which the Company gives notice
under this Section 3 is for an underwritten offering, the Company shall so
advise the Purchasers. In such event, the right of any such Purchaser to be
included in any such registration statement pursuant to this Section 3 shall be
conditioned upon such Purchaser's participation in such underwriting and the
inclusion of such Common Shares in the underwriting to the extent provided
herein. The Company, and the Purchasers who intend to participate in such
underwritten offering, shall enter into an underwriting agreement in customary
form with an underwriter or underwriters selected for such underwriting by the
Company.

          (i) To the fullest extent permitted by law, the Company will indemnify
and hold harmless each holder selling Common Shares under the registration
statement, each other entity or person who participates in the offering of the
Common Shares under such registration statement, and each other entity or
person, if any, who controls (within the meaning of the Securities Act) such
seller or participating entity or person (individually and collectively, the
"Indemnified Person"), against any losses, claims, damages or liabilities (joint
or several) to which they may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (joint or several), or actions in respect thereof, arise
out of or are based upon: (i) any untrue statement or alleged untrue statement
of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law, and the Company shall pay to each such Indemnified Person,
as incurred, any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the Company shall not be liable to
any Indemnified Person in any such case for any such loss, claim, damage,
liability, or action to the extent that it arises out of or is based upon (i)
any untrue statement or alleged untrue statement or omission or alleged omission
in such registration statement, preliminary or final prospectus, or amendment or
supplement thereto in reliance upon and in conformity with written information
furnished to the Company by such person expressly for use therein or (ii) such
person's failure to deliver a prospectus as required by the Securities Act.

Agreement, to exercise any right or privilege in this Agreement conferred, or
the waiver by said party of any breach of any of the terms, covenants or

any such terms, covenants, conditions, rights or privileges, but the same shall
continue and remain in full force and effect as if no such forbearance or waiver
had occurred. No waiver shall be effective unless it is in writing and signed by
an authorized representative of the waiving party. A breach of any
