COMMON STOCK PURCHASE AGREEMENT

      COMMON STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of October 18,
2005, by and between XETHANOL COPORATION, a Delaware corporation (the
"Company"), and FUSION CAPITAL FUND II, LLC, an Illinois limited liability
company (the "Buyer"). Capitalized terms used herein and not otherwise defined
herein are defined in Section 10 hereof.

                                    WHEREAS:

      Subject to the terms and conditions set forth in this Agreement, the
Company wishes to sell to the Buyer, and the Buyer wishes to buy from the
Company, up to Twenty Million Dollars ($20,000,000) of the Company's common
stock, par value $0.001 per share (the "Common Stock"). The shares of Common
Stock to be purchased hereunder are referred to herein as the "Purchase Shares."

        NOW THEREFORE, the Company and the Buyer hereby agree as follows:

      1. PURCHASE OF COMMON STOCK.

      Subject to the terms and conditions set forth in Sections 6, 7 and 9
below, the Company hereby agrees to sell to the Buyer, and the Buyer hereby
agrees to purchase from the Company, Purchase Shares as follows:

      (a) Commencement of Purchases of Common Stock. The purchase and sale of
Purchase Shares hereunder shall commence (the "Commencement") within five (5)
Trading Days following the date of satisfaction of the conditions to the
Commencement set forth in Sections 6 and 7 below (the date of such Commencement,
the "Commencement Date").

      (b) Buyer's Purchase Rights and Obligations. Subject to the Company's
right to suspend purchases under Section 1(d)(ii) hereof, the Buyer shall buy
Purchase Shares ("Daily Purchases") on each Trading Day during each Monthly
Period equal to the Daily Purchase Amount (as defined in Section 1(c)(i)) at the
Purchase Price. From time to time, the Company shall also have the right but not
the obligation, by its delivery to the Buyer of a Block Purchase Notice (as
defined in Section 1(c)(iv)), to require the Buyer to buy Purchase Shares (a
"Block Purchase") equal to the Block Purchase Amount (as defined in Section
1(c)(iv)) at the Block Purchase Price (as defined in Section 1(c)(iv)). The
Buyer shall pay to the Company an amount equal to the Purchase Amount with
respect to such Purchase Shares as full payment for the purchase of the Purchase
Shares so received. The Company shall not issue any fraction of a share of
Common Stock upon any purchase. If the issuance would result in the issuance of
a fraction of a share of Common Stock, the Company shall round such fraction of
a share of Common Stock up or down to the nearest whole share. All payments made
under this Agreement shall be made in lawful money of the United States of
America by check or wire transfer of immediately available funds to such account
as the Company may from time to time designate by written notice in accordance
with the provisions of this Agreement. Whenever any amount expressed to be due
by the terms of this Agreement is due on any day that is not a Trading Day, the
same shall instead be due on the next succeeding day which is a Trading Day.

      (c) The Daily Purchase Amount; Company's Right to Decrease or Increase the
Daily Purchase Amount; the Block Purchase Amount.

            (i) The Daily Purchase Amount. As used herein the term "Original
      Daily Purchase Amount" shall mean Forty Thousand Dollars ($40,000) per
      Trading Day. As used herein, the term "Daily Purchase Amount" shall mean
      initially Forty Thousand Dollars ($40,000) per Trading Day, which amount
      may be increased or decreased from time to time pursuant to this Section
      1(c).


                                       1

            (ii) Company's Right to Decrease the Daily Purchase Amount. The
      Company shall always have the right at any time to decrease the amount of
      the Daily Purchase Amount by delivering written notice (a "Daily Purchase
      Amount Decrease Notice") to the Buyer which notice shall specify the new
      Daily Purchase Amount. The decrease in the Daily Purchase Amount shall
      become effective one Trading Day after receipt by the Buyer of the Daily
      Purchase Amount Decrease Notice. Any purchases by the Buyer which have a
      Purchase Date on or prior to the first (1st) Trading Day after receipt by
      the Buyer of a Daily Purchase Amount Decrease Notice must be honored by
      the Company as otherwise provided herein. The decrease in the Daily
      Purchase Amount shall remain in effect until the Company delivers to the
      Buyer a Daily Purchase Amount Increase Notice (as defined below).

            (iii) Company's Right to Increase the Daily Purchase Amount. The
      Company shall have the right (but not the obligation) to increase the
      amount of the Daily Purchase Amount in accordance with the terms and
      conditions set forth in this Section 1(c)(iii) by delivering written
      notice to the Buyer stating the new amount of the Daily Purchase Amount (a
      "Daily Purchase Amount Increase Notice"). A Daily Purchase Amount Increase
      Notice shall be effective five (5) Trading Days after receipt by the
      Buyer. The Company shall always have the right at any time to increase the
      amount of the Daily Purchase Amount up to the Original Daily Purchase
      Amount. With respect to increases in the Daily Purchase Amount above the
      Original Daily Purchase Amount, as the market price for the Common Stock
      increases the Company shall have the right from time to time to increase
      the Daily Purchase Amount as follows. For every $0.25 increase in
      Threshold Price above $5.00 (subject to equitable adjustment for any
      reorganization, recapitalization, non-cash dividend, stock split or other
      similar transaction), the Company shall have the right to increase the
      Daily Purchase Amount by up to an additional $4,000 in excess of the
      Original Daily Purchase Amount. "Threshold Price" for purposes hereof
      means the lowest Sale Price of the Common Stock during the five (5)
      consecutive Trading Days immediately prior to the submission to the Buyer
      of a Daily Purchase Amount Increase Notice (subject to equitable
      adjustment for any reorganization, recapitalization, non-cash dividend,
      stock split or other similar transaction). For example, if the Threshold
      Price is $5.25, the Company shall have the right to increase the Daily
      Purchase Amount to up to $44,000 in the aggregate. If the Threshold Price
      is $6.00, the Company shall have the right to increase the Daily Purchase
      Amount to up to $56,000 in the aggregate. Any increase in the amount of
      the Daily Purchase Amount shall continue in effect until the delivery to
      the Buyer of a Daily Purchase Amount Decrease Notice. However, if at any
      time during any Trading Day the Sale Price of the Common Stock is below
      the applicable Threshold Price, such increase in the Daily Purchase Amount
      shall be void and the Buyer's obligations to buy Purchase Shares hereunder
      in excess of the applicable maximum Daily Purchase Amount shall be
      terminated. Thereafter, the Company shall again have the right to increase
      the amount of the Daily Purchase Amount as set forth herein by delivery of
      a new Daily Purchase Amount Increase Notice only if the Sale Price of the
      Common Stock is above the applicable Threshold Price on each of five (5)
      consecutive Trading Days immediately prior to such new Daily Purchase
      Amount Increase Notice.

            (iv) The Block Purchase Amount. As used herein the term "Block
      Purchase Amount" shall mean such Purchase Amount as specified by the
      Company in a Block Purchase Notice. As used herein the term "Block
      Purchase Notice" shall mean an irrevocable written notice from the Company
      to the Buyer directing the Buyer to buy the Purchase Amount in Purchase
      Shares as specified by the Company therein at the Block Purchase Price.
      For a Block Purchase Notice to be valid the following conditions must be
      met: (1) the Block Purchase Amount shall not exceed Two Hundred Fifty
      Thousand Dollars ($250,000) per Block Purchase Notice, (2) the Company
      must deliver the Purchase Shares on the same day as the Block Purchase
      Notice is delivered and (3) the Sale Price of the Common Stock must have
      been above $6.00 (subject to equitable adjustment for any reorganization,
      recapitalization, non-cash dividend, stock split or other similar
      transaction) during the ten (10) Trading Days prior to the delivery of the
      Block Purchase Notice. The Block Purchase Amount may be increased to up to
      $500,000 if the Sale Price of the Common Stock is above $9.00 (subject to
      equitable adjustment for any reorganization, recapitalization, non-cash
      dividend, stock split or other similar transaction) during the ten (10)
      Trading Days prior to the delivery of the Block Purchase Notice. The Block
      Purchase Amount may be increased to up to $750,000 if the Sale Price of
      the Common Stock is above $14.00 (subject to equitable adjustment for any
      reorganization, recapitalization, non-cash dividend, stock split or other
      similar transaction) during the ten (10) Trading Days prior to the
      delivery of the Block Purchase Notice. The Block Purchase Amount may be
      increased to up to $1,000,000 if the Sale Price of the Common Stock is
      above $20.00 (subject to equitable adjustment for any reorganization,
      recapitalization, non-cash dividend, stock split or other similar
      transaction) during the ten (10) Trading Days prior to the delivery of the
      Block Purchase Notice. The Company may deliver multiple Block Purchase
      Notices as it shall determine; provided however, at least ten (10) Trading
      Days must have passed since the most recent Block Purchase was completed.
      As used herein, the term "Block Purchase Price" shall mean the lesser of
      (i) the lowest Sale Price of the Common Stock on the Trading Day that a
      Block Purchase Notice was received by the Buyer or (ii) the lowest
      Purchase Price during the previous fifteen (15) Trading Days prior to the
      date that a Block Purchase Notice was received by the Buyer.

      (d) Limitations on Purchases.

            (i) Limitation on Beneficial Ownership. The Buyer shall not have the
      right or the obligation to purchase shares of Common Stock under this
      Agreement to the extent that after giving effect to such purchase the
      Buyer together with its affiliates would beneficially own in excess of
      9.9% of the outstanding shares of the Common Stock following such
      purchase. For purposes hereof, the number of shares of Common Stock
      beneficially owned by the Buyer and its affiliates or acquired by the
      Buyer and its affiliates, as the case may be, shall include the number of
      shares of Common Stock issuable in connection with a purchase under this
      Agreement with respect to which the determination is being made, but shall
      exclude the number of shares of Common Stock which would be issuable upon
      (1) a purchase of the remaining Available Amount which has not been
      submitted for purchase, and (2) exercise or conversion of the unexercised
      or unconverted portion of any other securities of the Company (including,
      without limitation, any notes or warrants) subject to a limitation on
      conversion or exercise analogous to the limitation contained herein
      beneficially owned by the Buyer and its affiliates. For purposes of this
      Section, in determining the number of outstanding shares of Common Stock
      the Buyer may rely on the number of outstanding shares of Common Stock as
      reflected in (1) the Company's most recent Form 10-QSB or Form 10-KSB, as
      the case may be, (2) a more recent public announcement by the Company or
      (3) any other written communication by the Company or its Transfer Agent
      setting forth the number of shares of Common Stock outstanding. Upon the
      reasonable written or oral request of the Buyer, the Company shall
      promptly confirm orally and in writing to the Buyer 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 any
      purchases under this Agreement by the Buyer since the date as of which
      such number of outstanding shares of Common Stock was reported. Except as
      otherwise set forth herein, for purposes of this Section 1(d)(i),
      beneficial ownership shall be determined in accordance with Section 13(d)
      of the Securities Exchange Act of 1934, as amended.

            (ii) Company's Right to Suspend Purchases. The Company may, at any
      time, give written notice (a " Daily Purchase Suspension Notice") to the
      Buyer suspending Daily Purchases of Purchase Shares by the Buyer under
      this Agreement. The Daily Purchase Suspension Notice shall be effective
      only for Daily Purchases that have a Purchase Date later than one (1)
      Trading Day after receipt of the Daily Purchase Suspension Notice by the
      Buyer. Any Daily Purchase by the Buyer that has a Purchase Date on or
      prior to the first (1st) Trading Day after receipt by the Buyer of a Daily
      Purchase Suspension Notice from the Company must be honored by the Company
      as otherwise provided herein. Such Daily Purchase suspension shall
      continue in effect until a revocation in writing by the Company, at its
      sole discretion.

            (iii) Purchase Price Floor. The Company shall not affect any sales
      under this Agreement and the Buyer shall not have the right nor the
      obligation to purchase any Purchase Shares under this Agreement on any
      Trading Day where the Purchase Price for any purchases of Purchase Shares
      would be less than the Floor Price. "Floor Price" means $2.00, which shall
      be appropriately adjusted for any reorganization, recapitalization,
      non-cash dividend, stock split or other similar transaction.

      (e) Records of Purchases. The Buyer and the Company shall each maintain
records showing the remaining Available Amount at any give time and the dates
and Purchase Amounts for each purchase or shall use such other method,
reasonably satisfactory to the Buyer and the Company.

      (f) Taxes. The Company shall pay any and all transfer, stamp or similar
taxes that may be payable with respect to the issuance and delivery of any
shares of Common Stock to the Buyer made under this Agreement.

as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Securities.

      (e) No Governmental Review. The Buyer understands that no United States

exists permitting such Securities to be sold, assigned or transferred without
such registration; (ii) any sale of the Securities made in reliance on Rule 144
may be made only in accordance with the terms of Rule 144 and further, if Rule

with some other exemption under the 1933 Act or the rules and regulations of the
SEC thereunder; and (iii) neither the Company nor any other person is under any
obligation to register the Securities under the 1933 Act or any state securities
laws or to comply with the terms and conditions of any exemption thereunder.

thereof, (ii) the execution and delivery of the Transaction Documents by the
Company and the consummation by it of the transactions contemplated hereby and
thereby, including without limitation, the issuance of the Commitment Shares and

constitute, the valid and binding obligations of the Company enforceable against
the Company in accordance with their terms, except as such enforceability may be
limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally, the enforcement of creditors' rights and remedies. The
Board of Directors of the Company has approved the resolutions (the "Signing
Resolutions") substantially in the form as set forth as Exhibit C-1 attached
hereto to authorize this Agreement and the transactions contemplated hereby. The
Signing Resolutions are valid, in full force and effect and have not been
modified or supplemented in any respect other than by the resolutions set forth
in Exhibit C-2 attached hereto regarding the registration statement referred to

copy of a unanimous written consent adopting the Signing Resolutions executed by
all of the members of the Board of Directors of the Company. No other approvals

Company is not required to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency or any

perform any of its obligations under or contemplated by the Transaction
Documents in accordance with the terms hereof or thereof. Except as disclosed in

the SEC pursuant to the reporting requirements of the 1934 Act (all of the
foregoing filed prior to the date hereof and all exhibits included therein and
financial statements and schedules thereto and documents incorporated by
reference therein being hereinafter referred to as the "SEC Documents"). As of
their respective dates (except as they have been correctly amended), the SEC
Documents complied in all material respects with the requirements of the 1934
Act and the rules and regulations of the SEC promulgated thereunder applicable
to the SEC Documents, and none of the SEC Documents, at the time they were filed
with the SEC (except as they may have been properly amended), 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. As of
their respective dates (except as they have been properly amended), the
financial statements of the Company included in the SEC Documents complied as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto. Such financial
statements have been prepared in accordance with generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise indicated in such financial statements or the notes thereto or (ii)
in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Company as of the dates thereof
and the results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments). Except as listed in Schedule 3(f), the Company has received no
notices or correspondence from the SEC since January 1, 2005. The SEC has not
commenced any enforcement proceedings against the Company or any of its

currently expect to take any steps, to seek protection pursuant to any
Bankruptcy Law nor does the Company or any of its Subsidiaries have any
knowledge or reason to believe that its creditors intend to initiate involuntary
bankruptcy or insolvency proceedings. The Company is financially solvent and is
generally able to pay its debts as they become due.

or any of its Subsidiaries, threatened against or affecting the Company, the
Common Stock or any of the Company's Subsidiaries or any of the Company's or the
Company's Subsidiaries' officers or directors in their capacities as such, which
could reasonably be expected to have a Material Adverse Effect. A description of
each action, suit, proceeding, inquiry or investigation before or by any court,
public board, government agency, self-regulatory organization or body which, as
of the date of this Agreement, is pending or threatened in writing against or
affecting the Company, the Common Stock or any of the Company's Subsidiaries or
any of the Company's or the Company's Subsidiaries' officers or directors in
their capacities as such, is set forth in Schedule 3(h).

      (i) Acknowledgment Regarding Buyer's Status. The Company acknowledges and
agrees that the Buyer is acting solely in the capacity of arm's length purchaser
with respect to the Transaction Documents and the transactions contemplated
hereby and thereby. The Company further acknowledges that the Buyer is not
acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to the Transaction Documents and the transactions
contemplated hereby and thereby and any advice given by the Buyer or any of its
representatives or agents in connection with the Transaction Documents and the
transactions contemplated hereby and thereby is merely incidental to the Buyer's
purchase of the Securities. The Company further represents to the Buyer that the
Company's decision to enter into the Transaction Documents has been based solely
on the independent evaluation by the Company and its representatives and
advisors.

      (j) No General Solicitation. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has engaged in any
form of general solicitation or general advertising (within the meaning of
Regulation D under the 1933 Act) in connection with the offer or sale of the
Securities.

      (k) Intellectual Property Rights. The Company and its Subsidiaries own or
possess adequate rights or licenses to use all material trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. Except as set forth on Schedule 3(k), none of the
Company's material trademarks, trade names, service marks, service mark
registrations, service names, patents, patent rights, copyrights, inventions,
licenses, approvals, government authorizations, trade secrets or other
intellectual property rights have expired or terminated, or, by the terms and
conditions thereof, could expire or terminate within two years from the date of

service names, service marks, service mark registrations, trade secret or other
similar rights of others, or of any such development of similar or identical
trade secrets or technical information by others and, except as set forth on
Schedule 3(k), there is no claim, action or proceeding being made or brought
against, or to the Company's knowledge, being threatened against, the Company or
its Subsidiaries regarding trademark, trade name, patents, patent rights,
invention, copyright, license, service names, service marks, service mark
registrations, trade secret or other infringement, which could reasonably be
expected to have a Material Adverse Effect.

<PAGE>

      (l) Environmental Laws. To the best of the Company's knowledge, the
Company and its Subsidiaries (i) are in compliance with any and all applicable
foreign, federal, state and local laws and regulations relating to the
protection of human health and safety, the environment or hazardous or toxic
substances or wastes, pollutants or contaminants ("Environmental Laws"), (ii)
have received all permits, licenses or other approvals required of them under
applicable Environmental Laws to conduct their respective businesses and (iii)
are in compliance with all terms and conditions of any such permit, license or
approval, except where, in each of the three foregoing clauses, the failure to
so comply could not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect.

      (m) Title. The Company and its Subsidiaries have good and marketable title
in fee simple to all real property and good and marketable title to all personal
property owned by them which is material to the business of the Company and its
Subsidiaries, in each case free and clear of all liens, encumbrances and defects
except such as are described in Schedule 3(m) or such as do not materially
affect the value of such property and do not interfere with the use made and
proposed to be made of such property by the Company and any of its Subsidiaries.
Any real property and facilities held under lease by the Company and any of its
Subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as are not material and do not interfere with the use made
and proposed to be made of such property and buildings by the Company and its
Subsidiaries.

      (n) Insurance. The Company and each of its Subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has been refused any
insurance coverage sought or applied for and neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the condition,
financial or otherwise, or the earnings, business or operations of the Company
and its Subsidiaries, taken as a whole.

      (o) Regulatory Permits. The Company and its Subsidiaries possess all
material certificates, authorizations and permits issued by the appropriate
federal, state or foreign regulatory authorities necessary to conduct their
respective businesses, and neither the Company nor any such Subsidiary has
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit.

      (p) Tax Status. The Company and each of its Subsidiaries has made or filed
all federal and state income and all other material tax returns, reports and
declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply. There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

      (q) Transactions With Affiliates. Except as set forth on Schedule 3(q) and
other than the grant or exercise of stock options disclosed on Schedule 3(c),
none of the officers, directors, or employees of the Company is presently a
party to any transaction with the Company or any of its Subsidiaries (other than
for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has an interest or is an
officer, director, trustee or partner.

      (r) Application of Takeover Protections. The Company and its board of
directors have taken or will take prior to the Commencement Date all necessary
action, if any, in order to render inapplicable any control share acquisition,
business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Certificate of
Incorporation or the laws of the state of its incorporation which is or could
become applicable to the Buyer as a result of the transactions contemplated by
this Agreement, including, without limitation, the Company's issuance of the
Securities and the Buyer's ownership of the Securities.

      (s) Foreign Corrupt Practices. Neither the Company, nor any of its
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any of its Subsidiaries has, in the course of its
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any unlawful bribe, rebate, payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.


      4. COVENANTS.

      (a) Filing of Form 8-K and Registration Statement. The Company agrees that
it shall, within the time required under the 1934 Act file a Report on Form 8-K
disclosing this Agreement and the transaction contemplated hereby. The Company
shall also file within ten (10) Trading Days from the date hereof a new
registration statement covering the sale of the Commitment Shares and at least
5,000,000 Purchase Shares in accordance with the terms of the Registration
Rights Agreement between the Company and the Buyer, dated as of the date hereof
("Registration Rights Agreement") and up to 14,462,047 additional shares
(including 1,431,032 shares issuable upon the exercise of outstanding warrants
and 1,650,000 shares issuable upon the conversion of outstanding senior secured
royalty income notes) on behalf of certain other selling stockholders. After
such registration statement is declared effective by the SEC, the Company agrees
and acknowledges that any sales by the Company to the Buyer pursuant to this
Agreement are sales of the Company's equity securities in a transaction that is
registered under the 1933 Act.

      (b) Blue Sky. The Company shall take such action, if any, as is reasonably
necessary in order to obtain an exemption for or to qualify (i) the initial sale
of the Commitment Shares and any Purchase Shares to the Buyer under this
Agreement and (ii) any subsequent resale of the Commitment Shares and any
Purchase Shares by the Buyer, in each case, under applicable securities or "Blue
Sky" laws of the states of the United States in such states as is reasonably
requested by the Buyer from time to time, and shall provide evidence of any such
action so taken to the Buyer.

      (c) No Variable Priced Financing. Other than pursuant to this Agreement,
the Company agrees that beginning on the date of this Agreement and ending on
the date of termination of this Agreement (as provided in Section 11(k) hereof),
neither the Company nor any of its Subsidiaries shall, without the prior written
consent of the Buyer, contract for any equity financing (including any debt
financing with an equity component) or issue any equity securities of the
Company or any Subsidiary or securities convertible or exchangeable into or for
equity securities of the Company or any Subsidiary (including debt securities
with an equity component) which, in any case (i) are convertible into or
exchangeable for an indeterminate number of shares of common stock, (ii) are
convertible into or exchangeable for Common Stock at a price which varies with
the market price of the Common Stock, (iii) directly or indirectly provide for
any "re-set" or adjustment of the purchase price, conversion rate or exercise
price after the issuance of the security, or (iv) contain any "make-whole"
provision based upon, directly or indirectly, the market price of the Common
Stock after the issuance of the security, in each case, other than reasonable
and customary anti-dilution adjustments for issuance of shares of Common Stock
at a price which is below the market price of the Common Stock.


                                       11
<PAGE>

      (d) Listing. The Company shall promptly secure the listing of all of the
Purchase Shares and Commitment Shares upon each national securities exchange and
automated quotation system, if any, upon which shares of Common Stock are then
listed (subject to official notice of issuance) and shall maintain, so long as
any other shares of Common Stock shall be so listed, such listing of all such
securities from time to time issuable under the terms of the Transaction
Documents. The Company shall maintain the Common Stock's authorization for
quotation on the Principal Market. Neither the Company nor any of its
Subsidiaries shall take any action that would be reasonably expected to result
in the delisting or suspension of the Common Stock on the Principal Market. The
Company shall promptly, and in no event later than the following Trading Day,
provide to the Buyer copies of any notices it receives from the Principal Market
regarding the continued eligibility of the Common Stock for listing on such
automated quotation system or securities exchange. The Company shall pay all
fees and expenses in connection with satisfying its obligations under this
Section.

      (e) Limitation on Short Sales and Hedging Transactions. The Buyer agrees
that beginning on the date of this Agreement and ending on the date of
termination of this Agreement as provided in Section 11(k), the Buyer and its
agents, representatives and affiliates shall not in any manner whatsoever enter
into or effect, directly or indirectly, any (i) "short sale" (as such term is
defined in Rule 3b-3 of the 1934 Act) of the Common Stock or (ii) hedging
transaction, which establishes a net short position with respect to the Common
Stock.

      (f) Issuance of Commitment Shares; Limitation on Sales of Commitment
Shares. Immediately upon the execution of this Agreement, the Company shall
issue to the Buyer 303,556 shares of Common Stock (the "Commitment Shares"). The
Commitment Shares shall be issued in certificated form and (subject to Section 5
hereof) shall bear the following restrictive legend:

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
      REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
      APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED
      FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR
      ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR
      THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
      APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF HOLDER'S COUNSEL,
      IN A CUSTOMARY FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID
      ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO
      RULE 144 UNDER SAID ACT.

      The Buyer agrees that the Buyer shall not transfer or sell the Commitment
Shares until the earlier of 500 Trading Days (25 Monthly Periods) from the date
hereof or the date on which this Agreement has been terminated, provided,
however, that such restrictions shall not apply: (i) in connection with any
transfers to or among affiliates (as defined in the 1934 Act), (ii) in
connection with any pledge in connection with a bona fide loan or margin
account, (iii) in the event that the Commencement does not occur on or before
February 28, 2006, due to the failure of the Company to satisfy the conditions
set forth in Section 7 or (iv) if an Event of Default has occurred, or any event
which, after notice and/or lapse of time, would become an Event of Default,
including any failure by the Company to timely issue Purchase Shares under this
Agreement. Notwithstanding the forgoing, the Buyer may transfer Commitment
Shares to a third party in order to settle a sale made by the Buyer where the
Buyer reasonably expects the Company to deliver Purchase Shares to the Buyer
under this Agreement so long as the Buyer maintains ownership of the same
overall number of shares of Common Stock by "replacing" the Commitment Shares so
transferred with Purchase Shares when the Purchase Shares are actually issued by
the Company to the Buyer.


                                       12

      (g) Due Diligence. The Buyer shall have the right, from time to time as
the Buyer may reasonably deem appropriate, to perform reasonable due diligence
on the Company during normal business hours. The Company and its officers and
employees shall provide information and reasonably cooperate with the Buyer in
connection with any reasonable request by the Buyer related to the Buyer's due
diligence of the Company, including, but not limited to, any such request made
by the Buyer in connection with (i) the filing of the registration statement
described in Section 4(a) hereof and (ii) the Commencement. Each party hereto
agrees not to disclose any Confidential Information of the other party to any
third party and shall not use the Confidential Information for any purpose other
than in connection with, or in furtherance of, the transactions contemplated
hereby. Each party hereto acknowledges that the Confidential Information shall
remain the property of the disclosing party and agrees that it shall take all
reasonable measures to protect the secrecy of any Confidential Information
disclosed by the other party.

      (h) Participation Rights. For a period of 25 months from the Commencement
Date (unless sooner terminated) and except as provided below in this Section
4(h), the Company hereby grants to the Buyer a right to participate in the
purchase of any New Securities (as defined below) that the Company may, from
time to time, propose to issue and sell in connection with any financing
transaction, as follows. Not later than 5 Trading Days prior to the execution of
any definitive documentation relating to the sale of any New Securities to any
persons or entities other than the Buyer or an Affiliate of the Buyer (a "New
Person"), the Company shall deliver written notice to Buyer of its intent to
enter into any such transaction, describing each of the New Persons and the type
of New Securities in reasonable detail, and attaching to such notice copies of
such definitive documentation. The Buyer shall have 15 Trading Days after
receipt of such notice to purchase up to 25% of such New Securities or any
portion thereof, at the price and on the terms specified in such notice by
giving written notice to the Company specifying the amount of New Securities to
be purchased by the Buyer, provided, however, that the Buyer shall not have the
right to purchase any such New Securities or portion thereof, if the number of
New Persons purchasing 100% of such New Securities as specified on such notice,
consists of two (2) or fewer entities. In the event the Company has not sold
such New Securities to the New Persons within 10 Trading Days after notice
thereof to the Buyer, the Company shall not thereafter issue or sell any New
Securities to any New Persons without first again complying with this Section.
"New Securities" shall mean any shares of Common Stock, preferred stock or any
other equity securities of the Company or securities convertible or exchangeable
for equity securities of the Company, provided, however, that New Securities
shall not include, (i) shares of Common Stock issuable upon conversion or
exercise of any securities outstanding as of the date hereof, (ii) shares,
options or warrants for Common Stock granted to officers, directors and
employees and consultants of the Company pursuant to incentive compensation
plans approved by the Board of Directors of the Company, (iii) shares of Common
Stock or securities convertible or exchangeable for Common Stock issued pursuant
to the acquisition of another company by consolidation, merger, or purchase of
all or substantially all of the assets of such company and pursuant to any
related acquisition financing or (iv) shares of Common Stock or securities
convertible or exchangeable into shares of Common Stock issued in connection
with a strategic transaction involving the Company and issued to an entity or an
affiliate of such entity that is engaged in the same or substantially related
business as the Company. The Buyer rights hereunder shall not prohibit or limit
the Company from selling any New Securities so long as the Company makes the
same offer to the Buyer as provided herein. Otherwise the Company shall be
prohibited from selling any New Securities to any New Person until it fully
complies herewith.

Company's other obligations under the Transaction Documents, the Company shall
defend, protect, indemnify and hold harmless the Buyer and all of its
affiliates, shareholders, officers, directors, employees and direct or indirect
investors and any of the foregoing person's agents or other representatives
(including, without limitation, those retained in connection with the
transactions contemplated by this Agreement) (collectively, the "Indemnitees")
from and against any and all actions, causes of action, suits, claims, losses,
costs, penalties, fees, liabilities and damages, and expenses in connection
therewith (irrespective of whether any such Indemnitee is a party to the action
for which indemnification hereunder is sought), and including reasonable
attorneys' fees and disbursements (the "Indemnified Liabilities"), incurred by
any Indemnitee as a result of, or arising out of, or relating to (a) any
misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, (b) any breach of any covenant,
agreement or obligation of the Company contained in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby, or
(c) any cause of action, suit or claim brought or made against such Indemnitee
and arising out of or resulting from the execution, delivery, performance or
enforcement of the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, other than with respect to Indemnified
Liabilities which directly and primarily result from the gross negligence or
willful misconduct of the Indemnitee. To the extent that the foregoing
undertaking by the Company may be unenforceable for any reason, the Company
shall make the maximum contribution to the payment and satisfaction of each of
the Indemnified Liabilities which is permissible under applicable law.

Company and its shareholders. All other questions concerning the construction,
validity, enforcement and interpretation of this Agreement and the other

or proceeding is brought in an inconvenient forum or that the venue of such
suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.

shall become effective when counterparts have been signed by each party and

      (k) Termination. This Agreement may be terminated only as follows:

            (i) By the Buyer any time an Event of Default exists without any
      liability or payment to the Company. However, if pursuant to or within the
      meaning of any Bankruptcy Law, the Company commences a voluntary case or
      any Person commences a proceeding against the Company, a Custodian is
      appointed for the Company or for all or substantially all of its property,
      or the Company makes a general assignment for the benefit of its
      creditors, (any of which would be an Event of Default as described in
      Sections 9(f), 9(g) and 9(h) hereof) this Agreement shall automatically
      terminate without any liability or payment to the Company without further
      action or notice by any Person. No such termination of this Agreement
      under this Section 11(k)(i) shall affect the Company's or the Buyer's
      obligations under this Agreement with respect to pending purchases and the
      Company and the Buyer shall complete their respective obligations with
      respect to any pending purchases under this Agreement.

            (ii) In the event that the Commencement shall not have occurred, the
      Company shall have the option to terminate this Agreement for any reason
      or for no reason without liability of any party to any other party.

            (iii) In the event that the Commencement shall not have occurred on
      or before February 28, 2006, due to the failure to satisfy the conditions
      set forth in Sections 6 and 7 above with respect to the Commencement (and
      the nonbreaching party's failure to waive such unsatisfied condition(s)),
      the nonbreaching party shall have the option to terminate this Agreement
      at the close of business on such date or thereafter without liability of
      any party to any other party.

            (iv) If by the Maturity Date, for any reason or for no reason the
      full Available Amount under this Agreement has not been purchased as
      provided for in Section 1 of this Agreement, by the Buyer without any
      liability or payment to the Company.


                                       22
<PAGE>

            (v) At any time after the Commencement Date, the Company shall have
      the option to terminate this Agreement for any reason or for no reason by
      delivering notice (a "Company Termination Notice") to the Buyer electing
      to terminate this Agreement without any liability or payment to the Buyer.
      The Company Termination Notice shall not be effective until one (1)
      Trading Day after it has been received by the Buyer.

            (vi) This Agreement shall automatically terminate on the date that
      the Company sells and the Buyer purchases the full Available Amount as
      provided herein, without any action or notice on the part of any party.

Except as set forth in Sections 11(k)(i) (in respect of an Event of Default
under Sections 9(f), 9(g) and 9(h)) and 11(k)(vi), any termination of this
Agreement pursuant to this Section 11(k) shall be effected by written notice
from the Company to the Buyer, or the Buyer to the Company, as the case may be,
setting forth the basis for the termination hereof. The representations and
warranties of the Company and the Buyer contained in Sections 2 and 3 hereof,
the indemnification provisions set forth in Section 8 hereof and the agreements
and covenants set forth in Sections 4(h) and 11, shall survive the Commencement
and any termination of this Agreement. No termination of this Agreement shall
affect the Company's or the Buyer's rights or obligations (i) under the
Registration Rights Agreement which shall survive any such termination or (ii)
under this Agreement with respect to pending purchases and the Company and the
Buyer shall complete their respective obligations with respect to any pending
purchases under this Agreement.

      (l) No Financial Advisor, Placement Agent, Broker or Finder. The Company
represents and warrants to the Buyer that it has not engaged any financial
advisor, placement agent, broker or finder in connection with the transactions
contemplated hereby. The Buyer represents and warrants to the Company that it
has not engaged any financial advisor, placement agent, broker or finder in
connection with the transactions contemplated hereby. The Company shall be
responsible for the payment of any fees or commissions, if any, of any financial
advisor, placement agent, broker or finder relating to or arising out of the
transactions contemplated hereby. The Company shall pay, and hold the Buyer
harmless against, any liability, loss or expense (including, without limitation,
attorneys' fees and out of pocket expenses) arising in connection with any such
claim.

      (m) No Strict Construction. The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual intent,
and no rules of strict construction will be applied against any party.

      (n) Remedies, Other Obligations, Breaches and Injunctive Relief. The
Buyer's remedies provided in this Agreement shall be cumulative and in addition
to all other remedies available to the Buyer under this Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive
relief), no remedy of the Buyer contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein
shall limit the Buyer's right to pursue actual damages for any failure by the
Company to comply with the terms of this Agreement. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
the Buyer and that the remedy at law for any such breach may be inadequate. The
Company therefore agrees that, in the event of any such breach or threatened
breach, the Buyer shall be entitled, in addition to all other available
remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.

      (o) Changes to the Terms of this Agreement. This Agreement and any
provision hereof may only be amended by an instrument in writing signed by the
Company and the Buyer. The term "Agreement" and all reference thereto, as used
throughout this instrument, shall mean this instrument as originally executed,
or if later amended or supplemented, then as so amended or supplemented.

      (p) Enforcement Costs. If: (i) this Agreement is placed by the Buyer in
the hands of an attorney for enforcement or is enforced by the Buyer through any
legal proceeding; or (ii) an attorney is retained to represent the Buyer in any
bankruptcy, reorganization, receivership or other proceedings affecting
creditors' rights and involving a claim under this Agreement; or (iii) an
attorney is retained to represent the Buyer in any other proceedings whatsoever
in connection with this Agreement, then the Company shall pay to the Buyer, as
incurred by the Buyer, all reasonable costs and expenses including attorneys'
fees incurred in connection therewith, in addition to all other amounts due
hereunder. Notwithstanding the foregoing, in the case of clauses (i) and (iii)
above, the Buyer shall not be entitled to such reasonable costs and expenses
unless the Buyer is the prevailing party.

      (q) Failure or Indulgence Not Waiver. No failure or delay in the exercise
of any power, right or privilege hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such power, right or privilege
preclude other or further exercise thereof or of any other right, power or
privilege.
