	RBC Bank	  	 Commercial Promissory Note
 (SD-L&S)

	  	Atlanta, Georgia

 MASTER NOTE 
 FOR VALUE RECEIVED, the undersigned (whether one or more, “Borrower”) promises to pay to RBC BANK (USA) (“Bank”), or order, the sum of Three Million Dollars ($3,000,000), or so much thereof as shall have been
disbursed from time to time and remains unpaid, together with interest at the rate and payable in the manner hereinafter stated. Principal and interest shall be payable at any banking office of Bank in the city or town indicated above, or such other
place as the holder of this Note may designate. 
 Article I. Interest Rate. 
 Section 1.1. Rate of Accrual. Interest will accrue on the unpaid principal balance at the rate set forth in Section 1.2.1 until maturity of this Note, whether such maturity occurs by
acceleration or on the Maturity Date; and, at Bank’s option, interest at the foregoing rate will accrue on any unpaid interest before such maturity. Interest will accrue on any unpaid balance owing under this Note, whether principal, interest,
fees, premiums, charges or costs and expenses, after maturity at the rate set forth in Section 1.2.2. All accrual rates of interest under this Note will be contract rates of interest, whether a pre-default rate or a default rate, and
references to contract rates in any loan documents executed and delivered by Borrower or others to Bank in connection with this Note shall be to such contract rates. 
 Section 1.2. Interest Rates. 
 1.2.1. Pre-Default Rate. Subject to the provisions of
Section 1.2.2 below, interest payable on this Note per annum will accrue at a floating per annum rate equal to two and three quarters percent (2.75%) plus the LIBOR Base Rate. The “LIBOR Base Rate” is the
London Interbank Offer Rate for U.S. Dollars for a term of one month which appears on Bloomberg Professional screen BBAM (or any generally recognized successor method or means of publication) as of 11:00 a.m., London time, two (2) London
business days prior to the day on which the rate will become effective. The rate for the first month or part thereof will initially become effective on the date of the Note as shown on the face hereof. Thereafter, the rate will change and a new rate
will become effective on the first calendar day of each succeeding month. If for any reason the London Interbank Offer Rate is not available, then the “LIBOR Base Rate” shall mean the rate per annum which banks charge each other in a
market comparable to England’s Eurodollar market on short-term money in U.S. Dollars for an amount substantially equivalent to the principal amount due under this Note as determined at 11:00 A.M., London time, two (2) London business days
prior to the day on which the rate will become effective, as determined in Bank’s sole discretion. Bank’s determination of such interest rate shall be conclusive, absent manifest error. 
 1.2.2. Default Rate. Upon the nonpayment of any payment of interest described herein, Bank, at its option and without accelerating this Note, may
accrue interest on such unpaid interest at a rate per annum (“Default Rate”) equal to the lesser of the maximum contract rate of interest that may be charged to and collected from Borrower on the loan evidenced by this Note under
applicable law or three percent (3.0%) plus the pre-default interest rate otherwise applicable hereunder, as set forth in Section 1.2.1. After maturity of this Note, whether by acceleration or otherwise, interest will accrue on the
unpaid principal of this Note, any accrued but unpaid interest and all fees, premiums, charges and costs and expenses owing hereunder at the Default Rate until this Note is paid in full, whether this Note is paid in full pre-judgement or
post-judgement. 

 1.2.3. Variable Rate; Calculation of Interest. 
 1.2.3.1. Variable Rate. This is a variable rate note. Any change in the rate of interest payable under this Note will equal the change in the
variable rate index to which such rate is tied, but the rate at which interest accrues under this Note shall never exceed the maximum contract rate which may be charged to and collected from Borrower on the loan evidenced by this Note under
applicable law. Bank shall have no obligation to notify Borrower of adjustments in the rate of interest payable under this Note. 
 1.2.3.2.
Calculation of Interest. All interest payable under this Note shall be calculated monthly and accrue daily on the basis of the actual number of days elapsed and a year of three hundred sixty (360) days. In computing the number of days
during which interest accrues, the day on which funds are initially advanced shall be included regardless of the time of day such advance is made, and the day on which funds are repaid shall be included unless repayment is credited prior to close of
business. Payments in federal funds, immediately available in the place designated for payment, received by Bank prior to 2:00 p.m. local time at said place of payment, shall be credited as if received prior to close of business on the day the funds
are immediately available; while other payments, at the option of Bank, may not be credited until such payments are immediately available to Bank, in federal funds, in the place designated for payment, prior to 2:00 p.m. local time at said place of
payment on a day on which Bank is open for business. 
 Article II. Payment Terms. 
 Section 2.1. Interest Payment Terms. Payments under this Note include an interest component and a principal component. The principal component is set forth
in Section 2.2 below. The interest component shall be paid as follows: interest shall be payable monthly, in arrears, beginning January 1, 2009 and continuing on the same calendar day of each consecutive month thereafter until the
Maturity Date, when all accrued but unpaid interest is due and payable in full. 
 Section 2.2. Principal Payment Terms; Maturity Date. As stated
in Section 2.1 above, payments under this Note include an interest component and a principal component. The interest component is set forth in Section 2.1 above. The principal component shall be paid as follows: principal
shall be payable in one single payment on December 31, 2010 (herein referred to as the “Maturity Date”). 
 Section 2.3. Prepayment.
This Note may be prepaid in whole, or in part at any time without any prepayment premium. 
 Section 2.4. Application of Payments. All payments
made on this Note shall be applied first to payment of all late fees, charges, premiums and costs and expenses due but unpaid under this Note, then to accrued but unpaid interest and finally to principal, in the inverse order of the payment dates
therefor, unless Bank determines in its sole discretion to apply payments in a different order or applicable law requires a different application of payments. The partial prepayment of this Note, if permitted, shall not result in a payment holiday
or any other deferral of any regularly scheduled payments under this Note, all of which shall be made as and when the same are scheduled to be paid. 
 Article III. Loan Agreement and Security. 
 Section 3.1. Loan Agreement. Borrower and Bank have entered into a loan and security
agreement dated of even date herewith (“Loan and Security Agreement”). Borrower shall perform and abide by, as and when so required, each and all of the covenants, terms and conditions imposed upon or applicable to Borrower in the Loan and
Security Agreement and all security documents and other agreements referenced in the Loan and Security Agreement. 
 Section 3.2. Security
Documents. This Note is secured by (1) the Loan and Security Agreement, (2) the security documents and other supporting obligations identified in the Loan and Security Agreement, (3) the security documents and other supporting
obligations which reference that they secure this Note or the Loan and Security Agreement, (4) any security documents and other supporting obligations which reference that they secure all indebtedness or other obligations owing from time to
time by Borrower to Bank, and 

 
(5) any security documents and other supporting obligations which reference that they secure all indebtedness from time to time owing from Borrower to
Bank other than consumer credit as defined under the Federal Reserve Board’s Regulation Z (Truth-in-Lending) (12 CFR 226 et seq.) (“security documents”). 
 Article IV. Default and Acceleration. 
 Section 4.1. Late Charges and Expenses. Borrower agrees to pay, upon
demand by Bank or if demand is not sooner made, on maturity of this Note, whether such maturity occurs by acceleration or on the Maturity Date, for each payment past due for fifteen (15) or more calendar days, a late charge in an amount equal
to the lesser of (1) three percent (3.0%) of the amount of the payment past due or (2) the maximum percentage of the payment past due permitted by applicable law, or the maximum amount if not expressed as a percentage. If this Note is
not paid in full whenever it becomes due and payable, Borrower agrees to pay all costs and expenses of collection, including reasonable attorneys’ fees. The Borrower hereby stipulates that reasonable attorneys’ fees shall be fifteen
percent (15%) of the outstanding balance (principal, interest, fees, premiums, charges and costs and expenses) owing under this Note after default and, if applicable law prohibits payment of attorneys’ fees when collection is through an
attorney who is a salaried employee of Bank, referral to an attorney not a salaried employee of the Bank. 
 Section 4.2. Default. The occurrence
of an Event of Default under the Loan and Security Agreement shall constitute an Event of Default under this Note. 
 Section 4.3. Acceleration.
Upon the occurrence of an Event of Default, or the occurrence of an event which, with the giving of notice or a lapse of time, or both, would become an Event of Default under this Note, (1) the entire unpaid principal balance of this Note,
together with all other amounts owing and all other amounts to be owing under this Note, shall, at the option of Bank, become immediately due and payable, without notice or demand, and (2) the Bank may, both before and after acceleration,
exercise any of and all of its other rights and remedies under this Note and the other loan documents, as well as any additional rights and remedies it may have at law and it may have in equity, to recover full payment of the balance (principal,
interest, fees, premiums, charges and costs and expenses) owing under this Note. The failure by Bank to exercise any of its options shall not constitute a waiver of the right to exercise same in the event of any subsequent default. 
 Article V. Miscellaneous. 
 Section 5.1. Use and
Application of Terms. To the end of achieving the full realization by Bank of its rights and remedies under this Note, including payment in full of the loan evidenced hereby, in using and applying the various terms, provisions and conditions in

and this Note shall inure to the benefit of any holder, its successors and assigns; and, Borrower waives and will not assert against any transferee or assignee of this Note any claims, defenses, set-offs or rights of recoupment which Borrower could
assert against Bank, except defenses which Borrower cannot waive. Borrower acknowledges that Customer Numbers and Loan Numbers may be added to this Note after execution and delivery of this Note by Borrower and if there is a section denoted
“BANK USE ONLY”, the information under such section may also be completed by Bank after execution and delivery of this Note. In addition, in the event the date of this Note is omitted, Borrower consents to Bank inserting the date.

 Section 5.8. Master Note. If this Note is designated herein as a MASTER NOTE or is denoted on Bank’s records as a MASTER NOTE, then this
Note evidences a line of credit and Borrower shall be liable for only so much of the principal amount as shall be equal to the total of the amounts advanced to or for Borrower by Bank from time to time, less all payments made by or for Borrower

 
and applied by Bank to principal, and for interest on each such advance, fees, premiums, charges and costs and expenses incurred or due hereunder, all as
shown on Bank’s books and records which shall be conclusive evidence of the amount owed by Borrower under this Note, absent a clear and convincing showing of bad faith or manifest error. If this is a MASTER NOTE, upon the occurrence of an Event
of Default or the occurrence of an event which, with the giving of notice or a lapse of time, or both, would become an Event of Default under this Note in addition to its other rights and remedies, Bank may terminate or suspend Borrower’s right
to receive any future or additional advances under this Note and the other loan documents.

            WARRANT AGREEMENT ("Agreement"), dated as of December 31, 2008 by
and between AIR INDUSTRIES GROUP INC., a Delaware corporation (the "Company"),
and TAGLICH BROTHERS, INC. ("Warrantholder").

            In consideration of the mutual terms, conditions, representations,
warranties and agreements herein set forth, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto hereby agree as follows:

Section 1.  Issuance of Warrants.

            The Company hereby issues and grants to Warrantholder 137,138
warrants ("Warrants") to purchase shares of Series B Convertible Preferred Stock
of the Company (the "Preferred Stock"). Each Warrant shall entitle the holder,
subject to the satisfaction of the conditions to exercise set forth in Section 7
of this Agreement, to purchase on or after the date hereof until December 31,
2015 (the "Warrant Expiration Date") one share of Preferred Stock (the shares of
Preferred Stock issuable upon exercise of the Warrants being collectively
referred to herein as the "Warrant Shares") at an exercise price of $0.01 per
Warrant Share (the "Exercise Price"). The shares of Preferred Stock issuable
upon exercise of the Warrants shall have the terms, preferences, rights and be
subject to the limitations set forth in the Certificate of Designation
previously filed with the Office of the Secretary of State of Delaware. The
number of Warrant Shares issuable on exercise of each Warrant and the Exercise
Price are all subject to adjustment pursuant to Section 8 of this Agreement.

Section 2.  Form of Warrant Certificates.

              Promptly after the execution and delivery of this Agreement by the
parties hereto, the Company shall cause to be executed and delivered to
Warrantholder one or more certificates evidencing the Warrants (the "Warrant
Certificates"). Each Warrant Certificate delivered hereunder shall be
substantially in the form set forth in Exhibit A attached hereto and may have
such letters, numbers or other identification marks and legends, summaries or
endorsements printed thereon as the Company may deem appropriate and that are
not inconsistent with the terms of this Agreement or as may be required by
applicable law, rule or regulation. Each Warrant Certificate shall be dated the
date of execution by the Company.

Section 3.  Execution of Warrant Certificates.

            Each Warrant Certificate delivered hereunder shall be signed on
behalf of the Company by its President or Chief Executive Officer and by its
Secretary or an Assistant Secretary. Each such signature may be in the form of a
facsimile thereof and may be imprinted or otherwise reproduced on the Warrant
Certificates.

            If any officer of the Company who signed any Warrant Certificate
ceases to be an officer of the Company before the Warrant Certificate so signed
shall have been delivered by the Company, such Warrant Certificate nevertheless
may be delivered as though such person had not ceased to be such officer of the
Company.

<PAGE>

Section 4.  Registration.

            Warrant Certificates shall be issued in registered form only. The
Company will keep or cause to be kept books for registration of ownership and
transfer of each Warrant Certificate issued pursuant to this Agreement. Each
Warrant Certificate issued pursuant to this Agreement shall be numbered by the
Company and shall be registered by the Company in the name of the holder thereof
(initially the Warrantholder). The Company may deem and treat the registered
holder of any Warrant Certificate as the absolute owner thereof (notwithstanding
any notation of ownership or other writing thereon made by anyone) for the
purpose of any exercise thereof and for all other purposes, and the Company
shall not be affected by any notice to the contrary.

Section 5.  Restrictions on Transfer.

            No Warrant may be sold, pledged, hypothecated, assigned, conveyed,
transferred or otherwise disposed of (each a "transfer") unless (i) the transfer
complies with all applicable securities laws and (ii) the transferee agrees in
writing to be bound by the terms of this Agreement and executes and delivers to
the Company any documents and instruments requested by the Company, including
without limitation, an opinion of counsel satisfactory to the Company, that such
transfer does not violate any applicable federal or state securities laws.

Section 6.  Mutilated or Missing Warrant Certificates.

            If any Warrant Certificate is mutilated, lost, stolen or destroyed,
the Company shall issue, upon surrender and cancellation of any mutilated
Warrant Certificate, or in lieu of and substitution for any lost, stolen or
destroyed Warrant Certificate, a new Warrant Certificate of like tenor and
representing an equal number of Warrants. In the case of a lost, stolen or
destroyed Warrant Certificate, a new Warrant Certificate shall be issued by the
Company only upon the Company's receipt of reasonably satisfactory evidence of
such loss, theft or destruction and, if requested, an indemnity or bond
reasonably satisfactory to the Company.

Section 7.  Exercise of Warrants.

            A. Exercise. Subject to the terms and conditions set forth in this
Section 7, Warrants may be exercised, in whole or in part (but not as to any
fractional part of a Warrant), at any time or from time to time after the date
hereof until on or prior to the Warrant Expiration Date.

            In order to exercise any Warrant, Warrantholder shall deliver to the
Company at its office referred to in Section 16 the following: (i) a written
notice in the form of the Election to Purchase appearing at the end of the form
of Warrant Certificate attached as Exhibit A hereto of such Warrantholder's
election to exercise the Warrants, which notice shall specify the number of such
Warrantholder's Warrants being exercised; (ii) the Warrant Certificate or
Warrant Certificates evidencing the Warrants being exercised; and (iii) payment
of the aggregate Exercise Price.

            All rights of Warrantholder with respect to any Warrant that has not
been exercised on or prior to the Warrant Expiration Date shall immediately
cease and such Warrants shall be automatically cancelled and void.

            1. B. Payment of Exercise Price. Payment of the Exercise Price with
respect to Warrants being exercised hereunder shall be by the payment to the
Company, in cash, by check or wire transfer, of an amount equal to the Exercise
Price multiplied by the number of Warrants then being exercised. The Warrants
also may be exercised at such time by means of a "cashless exercise" in which
the Holder shall be entitled to receive a certificate for the number of Warrant
Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

                                       2
<PAGE>

                  (A) =  the Fair Market Value of a Warrant Share as of the
                         date of exercise of the Warrants then being exercised;

                  (B) =  the Exercise Price of this Warrant, as adjusted; and

                  (X) =  the number of Warrant Shares issuable upon exercise
                         of the Warrant Certificates surrendered for exercise
                         in accordance with the terms of this Warrant Agreement
                         by means of a cash exercise rather than a cashless
                         exercise.

            C. Delivery of Warrant Shares. Upon receipt of the items referred to
in Section 7A, subject to any withholding that may be required by law and the
payment by the Warrantholder of any transfer taxes due if the warrant Shares are
to be registered in a name other than that of Warrantholder, the Company shall,
as promptly as practicable, execute and deliver or cause to be executed and
delivered, to or upon the written order of Warrantholder, and in the name of
Warrantholder or Warrantholder's designee, a stock certificate or stock
certificates representing the number of Warrant Shares to be issued on exercise
of the Warrant(s). The certificates issued to Warrantholder or its designee
shall bear any restrictive legend required under applicable law, rule or
regulation. A Warrant shall be deemed to have been exercised and such stock
certificate or stock certificates shall be deemed to have been issued, and such
holder or any other Person so designated to be named therein shall be deemed to
have become a holder of record of such shares for all purposes, as of the date
that such notice, together with payment of the aggregate Exercise Price and the
Warrant Certificate or Warrant Certificates evidencing the Warrants to be
exercised, is received by the Company as aforesaid. If the Warrants evidenced by
any Warrant Certificate are exercised in part, the Company shall, at the time of
delivery of the stock certificates, deliver to the holder thereof a new Warrant
Certificate evidencing the Warrants that were not exercised or surrendered,
which shall in all respects (other than as to the number of Warrants evidenced
thereby) be identical to the Warrant Certificate being exercised. Any Warrant
Certificates surrendered upon exercise of Warrants shall be canceled by the
Company.

            D. Fair Market Value. For purposes of determining the number of
Warrant Shares issuable upon exercise of Warrants in accordance with the
preceding Subsection C, the Fair Market Value of the Warrant Shares shall mean
as of the date of exercise (the "Determination Date"): (i) if the Warrant Shares
are traded on an exchange or are quoted on the National Association of
Securities Dealers, Inc. automated quotation ("NASDAQ") National Market System,
the average of the closing or last sale price, respectively, of the Warrant
Shares as reported for the ten (10) trading days immediately preceding the
Determination Date; (ii) if the Warrant Shares are not traded on an exchange or
on the NASDAQ National Market System but are traded in the over-the-counter
market, then the average of the mean of the closing bid and asked prices for a
share of such stock reported for the ten (10) trading days immediately preceding
the Determination Date; and (iii) if the Warrant Shares are not publicly traded,
then as determined in good faith by the disinterested members of the Company's
Board of Directors as being the price per share which the Company could
reasonably obtain from a willing buyer (who is not an employee or director) for
authorized but unissued shares of Warrant Shares.

Section 8.  Adjustment of Number of Warrant Shares Issuable Upon Exercise of a
            Warrant and Adjustment of Exercise Price.

            A. Adjustment for Stock Splits, Stock Dividends, Recapitalizations.
The number of Warrant Shares issuable upon exercise of each Warrant and the
Exercise Price shall each be proportionately adjusted to reflect any stock
dividend, stock split, reverse stock split, recapitalization or the like
affecting the number of outstanding shares of Preferred Stock that occurs after
the date hereof.

                                       3
<PAGE>

            B. Adjustments for Reorganization, Consolidation, Merger. If after
the date hereof, the Company (or any other entity, the stock or other securities
of which are at the time receivable on the exercise of the Warrants),
consolidates with or merges into another entity or conveys all or substantially
all of its assets to another entity, then, in each such case, Warrantholder,
upon any permitted exercise of a Warrant (as provided in Section 7), at any time
after the consummation of such reorganization, consolidation, merger or
conveyance, shall be entitled to receive, in lieu of the stock or other
securities and property receivable upon the exercise of the Warrant prior to
such consummation, the stock or other securities or property to which such
Warrantholder would have been entitled upon the consummation of such
reorganization, consolidation, merger or conveyance if such Warrantholder had
exercised the Warrant immediately prior thereto, subject to such further
adjustments as may be required as a result of the occurrence after such
consolidation or merger of the events described in this Section 8. The successor
or purchasing entity in any such reorganization, consolidation, merger or
conveyance (if other than the Company) shall duly execute and deliver to
Warrantholder a written acknowledgment of such entity's obligations under the
Warrants and this Agreement.

Section 9.  Reservation of Shares.

            The Company shall at all times reserve and keep available, free from
preemptive rights, out of the aggregate of its authorized but unissued Preferred
Stock, or its authorized and issued Preferred Stock held in its treasury, the
aggregate number of the Warrant Shares deliverable upon the exercise of all
outstanding Warrants, for the purpose of enabling it to satisfy any obligation
to issue the Warrant Shares upon the due and punctual exercise of the Warrants,
through the Warrant Expiration Date.

Section 10. No Impairment.

            The Company shall not, by amendment of its certificate of
incorporation or bylaws, or through reorganization, consolidation, merger,
dissolution, issuance or sale of securities, sale of assets or any other
voluntary action, willfully avoid or seek to avoid the observance or performance
of any of the terms of the Warrants or this Agreement, and shall at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate in order to protect the rights
of Warrantholder under the Warrants and this Agreement against wrongful
impairment. Without limiting the generality of the foregoing, the Company: (i)
shall not set or increase the par value of any Warrant Shares above the amount
payable therefor upon exercise, and (ii) shall take all actions that are
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable Warrant Shares upon the exercise of the Warrants.

Section 11. Representations and Warranties of Warrantholder.

            Warrantholder represents and warrants to the Company that, on the
date hereof and on the date the Warrantholder exercises the Warrant pursuant to
the terms of this Agreement:

                (i) Warrantholder is an "accredited investor", as such term is
defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

                (ii) Warrantholder understands that the Warrants and the Warrant
Shares have not been registered under the Securities Act and acknowledges that
the Warrants and the Warrant Shares must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration becomes available.

                                       4
<PAGE>

                (iii) Warrantholder is acquiring the Warrants for
Warrantholder's own account for investment and not with a view to, or for sale
in connection with, any distribution thereof.

Section 12. No Rights or Liabilities as Stockholder.

            No holder, as such, of any Warrant Certificate shall be entitled to
vote, receive dividends or be deemed the holder of Preferred Stock which may at
any time be issuable on the exercise of the Warrants represented thereby for any
purpose whatever, nor shall anything contained herein or in any Warrant
Certificate be construed to confer upon the holder of any Warrant Certificate,
as such, any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value or change of stock to no par value, consolidation,
merger, conveyance or otherwise), or to receive notice of meetings or other
actions affecting stockholders or to receive dividend or subscription rights, or
otherwise, until such Warrant Certificate shall have been exercised in
accordance with the provisions hereof and the receipt and collection of the
Exercise Price and any other amounts payable upon such exercise by the Company.
No provision hereof, in the absence of affirmative action by Warrantholder to
purchase Warrant Shares shall give rise to any liability of such holder for the
Exercise Price or as a stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company.

Section 13. Right of First Refusal.

            (a) The first time the Warrantholder receives a bona fide offer to
purchase Shares (as defined in this Section) which it intends to accept, the
Company shall have the right, but not the obligation, to purchase all but not
less than all of the Warrants Shares or the securities issuable upon conversion
of the Warrant Shares (the "Conversion Shares," and together with the Warrant
Shares, the "Shares"), as the case may be, to be sold from a Warrantholder at
the formula price set forth in subsection (b) below. For purposes hereof, a bona
fide sale is a sale of the entire right title and interest to the Shares at a
price reasonably approximating the then fair market value thereof, but shall not
include any sale to Taglich Brothers, Inc. ("Taglich") or an affiliate (as
defined in rule 405 promulgated under the Securities Act of 1933, as amended) of
Taglich or the Warrantholder. The Warrantholder shall give the Company written
notice of any proposed sale of Shares (the "Notice of Sale") not less than 10
days prior to the consummation of that sale (the "Scheduled Sale Date"), which
notice shall identify the proposed purchaser, the total and per Share purchase
price, the Scheduled Sale Date and other material terms of the proposed sale,
and shall be accompanied by a copy of the offer to purchase. The Shares which
are the subject of a Notice of Sale shall be referred to as the "Offered
Shares." The Company shall have 8 days from the receipt of the Notice of Sale to
notify the Warrantholder of its intention to exercise its right of first refusal
with respect to the proposed sale and must consummate the purchase of the
Offered Shares by the Scheduled Sale Date. The Company shall be deemed to have
declined to exercise its right of first refusal if the Company does not deliver
a timely Notice of Sale to the Holder or if the Notice of Sale is delivered to
the Warrantholder on a timely basis, the Company fails to consummate the sale by
the Scheduled Sale Date. If the first time the Warrantholder proposes to sell
Shares it is proposing to sell less than all of the Shares held by it, the
Company shall have a right of first refusal as provided herein when the
Warrantholder proposes to sell the balance of the Shares.

            (b) The per share purchase price of Offered Shares to be paid by the
Company upon exercise of the Company's right of first refusal set forth in
subsection (a) above shall be an amount equal to the excess of (i) the per Share
purchase price set forth in the Notice of Sale over (ii) $2.99 (the "Hurdle
Price"), provided that if the per share purchase price set forth in the Notice
of Sale is equal to or less than the Hurdle Price, upon exercise of its right of
first refusal the Company shall have the right to redeem all of the Offered

                                       5
<PAGE>

Shares for an aggregate consideration of $10.00 and further provided that upon
adjustment of the Warrant Shares as provided in Section 8 (subject to such
successive further adjustments as may be required as a result of the adjustment
of the securities issuable upon exercise of the Warrant Shares) or Conversion of
the Warrant Shares (subject to such successive further adjustments as may be
required as a result of the conversion of the securities issuable upon
conversion of the Warrant Shares) in accordance with the terms thereof, the
Hurdle Price shall be allocated pro-rata amongst the securities issuable upon
such adjustment or conversion. [Note - the $2.99 is a placeholder. The number is
intended to equal the fair market value of the Class B as determined for
purposes of allocating the purchase price received for subscriptions in
September 2008 less 1 cent. I am waiting for Scott to come back to get the
number]

            For example, if the per Share price offered to a Warrantholder for
Offered Shares (then comprised of Class B Preferred Stock) was $10.00, the price
payable by the Company upon exercise of the right of first refusal would be
$7.01 and if the per Share price offered to a Warrantholder for Offered Shares
(then comprised of Class B Preferred Stock) was $7.01 or less, the Company could
redeem the Offered Shares for an aggregate of $10.00.

            If a Warrantholder proposes to sell any Shares on an exchange or
over-the-counter, then, for purposes of determining the per share price at which
the Company may redeem the Offered Shares, the Fair Market Value of the Shares
(determined in accordance with Section 7 D) as of the date of the Notice of Sale
shall be substituted for the price which might have been offered by a third
party and set forth in the Notice of Sale.

            (c) The Warrantholder understands and acknowledges that the
certificate(s) evidencing the Warrant Shares and the Conversion Shares shall be
endorsed with a legend which refers to the Company's right of first refusal set
forth in this Section.
