                          SUBORDINATED PROMISSORY NOTE

$2,050,000.00                                                   August 24, 2007
                                                              New York, New York

      For good and valuable consideration, the receipt of which is hereby
acknowledged, Air Industries Group, Inc., a Delaware corporation (the
"Company"), promises to pay to the order of John Gantt and Lugenia Gantt or
their assigns (collectively, the "Holder"), the principal sum of Two Million
Fifty Thousand Dollars ($2,050,000.00), as such amount may be increased pursuant
to Section 1(d) of this Note, together with interest thereon as provided for
herein, which shall be payable as follows: $25,000 on each of October 31, 2008
and December 31, 2008, an additional $50,000 on March 31, 2009, followed by 19
equal consecutive quarterly installments of $100,000, commencing on June 30,
2009 and continuing through December 31, 2013, payable on the last business day
of each March, June, September and December, commencing June 30, 2009, and
continuing through and including December 31, 2013, and a final payment of
$50,000 on March 31, 2014, or, if earlier, (ii) when, upon or after the
occurrence of an Event of Default (as defined below), such amount is declared
due and payable by the Holder or made automatically due and payable in
accordance with the terms hereof (the "Maturity Date").

      Interest shall be accrue on any portion of the principal amount of this
Note outstanding from time to time until payment thereof in full, at a simple
rate of seven percent (7%) per annum, commencing on August 24, 2008.
Notwithstanding the foregoing, effective upon and during the continuance of
occurrence of an Event of Default (as hereinafter defined), the outstanding
balance of any amount owed under this Note shall bear interest ("Default
Interest") at the rate of eleven percent (11%) per annum, with the Default
Interest accruing from and including such date of the occurrence of an Event of
Default. Interest shall be calculated on the basis of a 365/366 day year and the
actual number of days elapsed. In no event shall the Holder hereof, or any
permitted successor or assign, be entitled to receive, collect or retain any
amount of interest paid hereon in excess of that permitted by applicable law.

      This Note may be prepaid in whole or in part at any time. All payments
made pursuant to this Note shall be applied first to reimbursable expenses
(including the expenses and costs described in Section 4(f) below), interest
accrued, if any, and then principal.

      This Note is issued pursuant to that certain Stock Purchase Agreement,
dated as of March 9, 2007, as amended by Amendment No.1 thereto dated as of
August 2, 2007 (the "Stock Purchase Agreement"), entered into between the
Company and the Holder, and as the terms of this Note as originally issued were
further amended by a letter dated August 14, 2008 signed by the Company and the
Holder.

      The following is a statement of rights of the Holder and the conditions to
which this Note is subject, and to which the Holder, by acceptance of this Note,
agrees:

                                       1
<PAGE>

      1. Subordination. (a) This Note will be subordinate and inferior to the
Company's Senior Indebtedness (as hereinafter defined). The Company for itself,
its successors and assigns, covenants and agrees and the Holder of this Note,
for himself, his successors and assigns, by his acceptance of this Note likewise
covenants and agrees that, to the extent provided below, the payment of all
amounts due pursuant to this Note is hereby expressly subordinated and junior in
right of payment to the extent and in the manner hereinafter set forth, to the
Company's Senior Indebtedness. As used herein, the term "Senior Indebtedness"
shall mean the principal of, and interest and premium, if any, on any and all,
(i) indebtedness of the Company for borrowed money or obligations with respect
to which the Company is a guarantor, to banks, insurance companies, or other
financial institutions or entities regularly engaged in the business of lending
money, in each case as in effect as of the date hereof or as may be borrowed
hereafter for working capital of the Company or one of its subsidiaries, or the
acquisition by the Company of one or more businesses, and (ii) any such
indebtedness or any debentures, notes or other evidence of indebtedness issued
in exchange for or to refinance such Senior Indebtedness, or any indebtedness
arising from the satisfaction of such Senior Indebtedness by a guarantor,
provided that such indebtedness issued in exchange for or to refinance Senior
Indebtedness or arising from the satisfaction of Senior Indebtedness by a
Guarantor is on commercially reasonable terms as of the date of incurrence not
to exceed the principal amount under such Senior Indebtedness and provided
further that the Company provides the Holder with prior written notice of such
action.

            (b) Upon the acceleration of any Senior Indebtedness or upon the
maturity of all or any portion of the principal amount of any Senior
Indebtedness by lapse of time, acceleration or otherwise, all such Senior
Indebtedness which has been so accelerated or matured shall first indefeasibly
be paid in full before any payment is made by the Company or any person acting
on behalf of the Company on account of any obligations evidenced by this Note.

            (c) The Company shall not pay any principal portion of this Note, or
interest accrued thereon, before the scheduled due date thereof if at such time
there exists a Blockage Event (as hereafter defined) and written notice thereof
has been given to the Company and the Holder by the holders of the Senior
Indebtedness.

            (d) A "Blockage Event" is deemed to exist for the period of time
commencing on the date of receipt by the Holder of written notice of the
occurrence of a Default or an Event of Default (as defined in the instruments
evidencing the Senior Indebtedness), which notice shall specify such Default or
Event of Default, and ending on:

                  (i) the date such Default or Event of Default under the Senior
Indebtedness, as applicable, is cured or waived, provided that such Default or
Event of Default is in the payment of any amount due thereunder; or

                  (ii) in the case of any other Default or Event of Default
under the Senior Indebtedness, the earlier of (A) the date on which such Default
or Event of Default shall have been cured or waived and (B) the date that is 180
days after the occurrence of such Default or Event of Default, provided that a
Blockage Event with respect to a single specified Default or Event of Default
may be deemed to occur only once for each twelve-month period, provided,
further, that no Default or Event of Default that existed at the commencement
of, or during the pendency of, a Blockage Event shall serve as the basis for the
institution of any subsequent Blockage Event.

                                       2
<PAGE>

      The Holder has the right, but not the obligation, to cure any such Default
or Event of Default under Senior Indebtedness to the extent it can be cured by
the payment of money. If the Holder shall have cured any such Default or Event
of Default under Senior Indebtedness to the extent such Default or Event of
Default can be cured by the payment of money, then such amount of interest as
shall have accrued on this Note during the continuance of the Blockage Event
(each, an "Additional Principal Amount") shall be added to the aggregate
principal amount then owing to the Holder pursuant to this Note. The Company
shall pay equal quarterly installments of each Additional Principal Amount
pursuant to the first paragraph of this Note from the date such Additional
Principal Amount is incurred pursuant to the first paragraph through and
including August 31, 2011, subject to all principal amounts being declared due
and payable or made automatically due and payable when, upon or after the
occurrence of an Event of Default under this Note.

            (e) At any time there exists a Blockage Event, (i) the Company shall
not, directly or indirectly, make any payment of any part of this Note, (ii) the
Holder shall not demand or accept from the Company or any other person any such
payment or cancel, set-off or otherwise discharge any part of the indebtedness
represented by this Note, and (iii) neither the Company nor the Holder shall
otherwise take or permit any action prejudicial to or inconsistent with the
priority position of any holder of Senior Indebtedness over the Holder of this
Note.

            (f) No right of any holder of Senior Indebtedness to enforce the
subordination provisions of this obligation shall be impaired by any act or
failure to act by the Company or the Holder or by their failure to comply with
this Note or any other agreement or document evidencing, related to or securing
the obligations hereunder. Without in any way limiting the generality of the
preceding sentence, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Holder, without incurring
responsibility to the Holder and without impairing or releasing the
subordination provided in this Note or the obligations of the Holder to the
holders of Senior Indebtedness, do any one or more of the following: (i) change
the manner, place or terms of payment of any Senior Indebtedness provided that
such change does not materially impact Holder in an adverse manner; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing any Senior Indebtedness; (iii) release any person or entity
liable in any manner for the collection of any Senior Indebtedness; and (iv)
exercise or refrain from exercising any rights against the Company or any other
person or entity.

            (g) In the event that the Company shall make any payment or
prepayment to the Holder on account of the obligations under this Note which is
prohibited by this Section, such payment shall be held by the Holder, in trust
for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Indebtedness (pro rata as to each of such holders on the basis
of the respective amounts and priorities of Senior Indebtedness held by them) to
the extent necessary to pay all Senior Indebtedness due to such holders of
Senior Indebtedness in full in accordance with its terms (whether or not such
Senior Indebtedness is due and owing), after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Indebtedness.

                                       3
<PAGE>

            (h) After all Senior Indebtedness indefeasibly is paid in full and
until the obligations under the Note are paid in full, the Holder shall be
subrogated to the rights of holders of Senior Indebtedness to the extent that
distributions otherwise payable to the Holder have been applied to the payment
of Senior Indebtedness. For purposes of such subrogation, no payments or
distributions to holders of such Senior Indebtedness of any cash, property or
securities to which the Holder would be entitled except for the provisions of
this Section and no payment over pursuant to the provisions of this Section to
holders of such Senior Indebtedness by the Holder, shall, as between the
Company, its creditors other than holders of such Senior Indebtedness, and the
Holder, be deemed to be a payment by the Company to or on account of such Senior
Indebtedness, it being understood that the provisions of this Section are solely
for the purpose of defining the relative rights of the holders of such Senior
Indebtedness, on the one hand and the Holder, on the other hand.

            (i) In any insolvency, receivership, bankruptcy, dissolution,
liquidation or reorganization proceeding, or in any other proceeding, whether
voluntary or involuntary, by or against the Company under any bankruptcy or
insolvency law or laws relating to relief of debtors, to compositions,
extensions or readjustments of indebtedness:

                  (i) the claims of any holders of Senior Indebtedness against
the Company shall be paid indefeasibly in full in cash or such payment shall
have been provided for in a manner acceptable to the holders of at least a
majority of the then outstanding principal amount of the Senior Indebtedness
before any payment is made to the Holder;

                  (ii) until all Senior Indebtedness is indefeasibly paid in
full in cash or such payment shall have been provided for in a manner acceptable
to the holders of at least a majority of the then outstanding principal amount
of the Senior Indebtedness before any payment is made to the Holder, any
distribution to which the Holder would be entitled but for this Section shall be
made to holders of Senior Indebtedness, except for distribution of securities
issued by the Company which are subordinate and junior in right of payment to
the Senior Indebtedness; and

                  (iii) the holders of Senior Indebtedness shall have the right
to enforce, collect and receive every such payment or distribution and give
acquittance therefor. If, in or as a result of any action case or proceeding
under Title 11 of the United States Code, as amended from time to time, or any
comparable statute, relating to the Company, the holders of the Senior
Indebtedness return, refund or repay to the Company, or any trustee or committee
appointed in such case or proceeding receive any payment or proceeds of any
collateral in connection with such action, case or proceeding alleging that the
receipt of such payments or proceeds by the holders of the Senior Indebtedness
was a transfer voidable under state or federal law, then the holders of the
Senior Indebtedness shall not be deemed ever to have received such payments or
proceeds for purposes of this Note in determining whether and when all Senior
Indebtedness has been paid in full and the Company shall pay or cause to be
paid, and the Holder shall be entitled to receive any such funds, proceeds or
collateral to satisfy all amounts due hereunder.. In the event the holders of
Senior Indebtedness receive amounts in excess of payment in full (cash) of
amounts outstanding in respect of Senior Indebtedness (without giving effect to
whether claims in respect of the Senior Indebtedness are allowed in any
insolvency proceeding), the holders of Senior Indebtedness shall pay such excess
amounts to the Holder.

                                       4
<PAGE>

            (k) By its acceptance of this Note, the Holder agrees to execute and
deliver such documents as may be reasonably requested from time to time by the
Company or the holder of any Senior Indebtedness in order to implement the
foregoing provisions of this Section.

      2. Events of Default. If any of the events specified in this Section shall
occur (herein individually referred to as an "Event of Default"), the Holder
may, so long as such condition exists, in addition to any other right, power or
remedy granted to the Holder under this Note, the Stock Purchase Agreement, the
Security Agreement (as hereinafter defined), or applicable law, either by suit
in equity or by action at law, or both, declare the entire principal amount (and
accrued interest thereon) and all other amounts immediately due and payable,
without presentment, demand or notice of any kind, all of which are expressly
waived, provided, however, that upon the occurrence of any Event of Default
described in Section 2(c) or 2(d) hereof, the entire principal amount (and
accrued interest thereon) and all other amounts shall automatically become due
and payable:

            (a) Payment of any portion of the principal of this Note or interest
accrued thereon shall be delinquent for a period of 10 days or more after the
due date thereof;

            (b) If the Company shall fail to observe any covenant or other
provision contained in this Note (other than with respect to payment), the Stock
Purchase Agreement or the Security Agreement and such failure of observance
shall be continuing for 10 days after the Holder has given written notice
thereof;

            (c) The institution by the Company of proceedings to be adjudicated
as bankrupt or insolvent, or the consent by it to institution of bankruptcy or
insolvency proceedings against it or the filing by it of a petition or answer or
consent seeking reorganization or release under the federal Bankruptcy Act, or
any other applicable federal or state law, or the consent by it to the filing of
any such petition or the appointment of a receiver, liquidator, assignee,
trustee or other similar official of the Company, or of any substantial part of
its property, or the making by it of an assignment for the benefit of creditors,
or the taking of corporate action by the Company in furtherance of any such
action;

            (d) If, within 45 days after the commencement of an action against
the Company (and service of process in connection therewith on the Company)
seeking any bankruptcy, insolvency, reorganization, liquidation, dissolution or
similar relief under any present or future statute, law or regulation, such
action shall not have been resolved in favor of the Company or all orders or
proceedings thereunder affecting the operations or the business of the Company
stayed, or if the stay of any such order or proceeding shall thereafter be set
aside, or if there is appointed without the consent or acquiescence of the
Company of any trustee, receiver or liquidator of the Company or of all or any
substantial part of the properties of the Company, such appointment shall not
have been vacated;

            (e) Any declared default of the Company under any Senior
Indebtedness whether now existing or hereafter created that gives the holder
thereof the right to accelerate such Senior Indebtedness, and such Senior
Indebtedness is in fact accelerated by the holder.

                                       5
<PAGE>

            (f) One or more judgments for the payment of money in an amount in
excess of $100,000 in the aggregate shall be rendered against the Company or any
of its subsidiaries (or any combination thereof) and shall remain undischarged
for a period of ten consecutive days during which execution shall not be
effectively stayed, or any action is legally taken by a judgment creditor to
levy upon any such judgment; or

            (g) Any representation or warranty made by the Company in the
Security Agreement or any other agreement between the Company and Holder is
false or incorrect in any material respect when made.

      4. Miscellaneous.

            (a) Waiver and Amendment. The rights and remedies herein reserved to
any party shall be cumulative and in addition to any other or further rights and
remedies available at law or in equity. The waiver by any party hereto of any
breach of any provision of this Note shall not be deemed to be a waiver of the
breach of any other provision or any subsequent breach of the same provision.
This Note and its terms may be changed, waived or amended only by the written
consent of the Company and the Holder and, if any such change, waiver, or
amendment is with respect to the subordination provisions, the holders of at
least a majority in the then-outstanding principal amount of the Senior
Indebtedness.

            (b) Governing Law. This Note shall be governed by and construed in
accordance with the law of the State of New York without regard to conflict of
law provisions. Any legal suit, action or proceeding arising out of or based
upon this Note shall be instituted in any federal or state court only in the
County of Suffolk, State of New York. The aforementioned choice of venue is
intended to be mandatory and not permissive in nature, thereby precluding the
possibility of litigation arising out of this Note in any jurisdiction other
than that specified in this Section. The Holder and the Company each waive, to
the fullest extent permitted by applicable law, any right it may have to assert
the doctrine of forum non conveniens or similar doctrine or to object to venue
with respect to any proceeding brought in accordance with this Section, and
stipulates that the state and federal courts located in the City and County of
New York, State of New York, shall have in personam jurisdiction and venue over
them for the purpose of litigation any dispute, controversy or proceeding
arising out of or related to this Note.

            (c) Successors and Assigns. All of the terms and provisions of this
Note shall be binding upon and inure to the benefit of the parties hereto and
their respective successors, heirs and permitted assigns.

            (d) Headings. The section headings contained in this Note are
intended solely for convenience of reference and do not themselves constitute a
part of this Note.

            (e) Severability. In case any provision contained herein (or part
thereof) shall for any reason be held to be invalid, illegal, or unenforceable
in any respect, such invalidity, illegality, or other unenforceability shall not
affect any other provision (or the remaining part of the affected provision)
hereof; but this Note shall be construed as if such invalid, illegal, or
unenforceable provision (or part thereof) had never been contained herein, but
only to the extent that such provision is invalid, illegal, or unenforceable.

                                       6

            (f) Costs of Collection. The Company shall reimburse Holder for all
reasonable costs and expenses, including without limitation, reasonable
attorneys' fees and expenses, incurred in connection with (i) drafting,
negotiating, executing and delivering any amendment, modification or waiver of,

                          Re.: Welding Metallurgy, Inc.

Dear John and Lugenia:

      Our Amended and Restated Promissory Note in your favor dated as of August
24, 2007 (the "Note"), is expressly subordinated to the payment of our Senior
Indebtedness as defined therein. As a condition to granting certain waivers,
Steel City Capital Funding LLC ("SCCF"), one of our senior lenders, requires
that neither Air Industries Group, Inc. nor any of its subsidiaries make any
further payments under the Note until April 30, 2010. As of the date hereof,
there is presently due and owing $2,043,871of principal and $157,548.50 of
interest, and interest is accruing at the default rate of $11% per annum. We
acknowledge that a default in our obligations under the Note has occurred and is
continuing and that we have no defenses or counterclaims relating thereto.

      We hereby request your consent to a modification of the Note to defer all
payments thereunder until the earlier of (a) the date all indebtedness owed by
the Company to SCCF is paid in full or (b) April 30, 2010 (collectively, the
"Forbearance Date"). Notwithstanding anything in the Note to the contrary,
during the period from the date hereof until the Forbearance Date, interest
shall accrue on the outstanding principal balance of the Note at the rate of 9%
per annum and thereafter shall accrue at the rate as provided in the Note.
Unless otherwise agreed, for purposes of determining the schedule pursuant to
which the outstanding principal balance of the Note is to be repaid, a Blockage
Event (as such term is defined in the Note) shall be deemed to be in existence
during the period from the date hereof until the Forbearance Date, and as of the
Forbearance Date, payments under the Note will resume as provided therein.
Except as modified herein, the Note remains in full force and effect.

      As consideration for your consent to the foregoing, simultaneously
herewith we shall pay to you a fee, not in reduction of amounts due under the
Note, of $50,000. Except as modified herein, this letter shall not constitute a
waiver of any rights or remedies which you may have under the Note or otherwise.

      If the foregoing is acceptable to you, please so signify by signing this
letter in the space provided below whereupon this letter shall become a binding
agreement among us and a modification of the terms of the Note.
