2.01(a) which is a Revolving Credit LIBOR Loan shall be for an aggregate

total Revolving Credit Commitments of all of the Lenders multiplied by (ii) the

under this Section 2.01 shall be made from the several Lenders ratably in
proportion to their respective Pro Rata Shares.  Within the foregoing limits,
the Company may borrow under this Section 2.01(a), prepay under Section 2.11 and

obligation to make Revolving Credit Loans as provided herein.

or before the date of this Agreement (with respect to the fiscal month of the
Company ended August 31, 2008) and on or before the fifteenth (15th) day of each

Loans outstanding as of the end of the immediately preceding fiscal month of the
Company;

            (v)        the difference, if any, between the Borrowing Base and
the Total Revolving Credit Outstandings as of the end of the immediately
preceding fiscal month of the Company.

The Borrowing Base shown in such Borrowing Base Certificate shall be and remain
the Borrowing Base hereunder until the next Borrowing Base Certificate is
delivered to the Agent and each Lender, at which time the Borrowing Base shall
be the amount shown in such subsequent Borrowing Base Certificate.  Each
Borrowing Base Certificate shall be certified (subject to normal year‑end
adjustments) as being true, correct and complete in all material respects by the
President or the Chief Financial Officer of the Company.

            (c)        If at any time the Total Revolving Credit Outstandings
are greater than the Borrowing Base as shown on the most recent Borrowing Base
Certificate, the Company shall be automatically required (without demand or
notice of any kind by the Agent or any Lender, all of which are hereby expressly
waived by the Company) to immediately repay the Revolving Credit Loans and/or
the Swing Line Loans and/or surrender for cancellation the outstanding Letters
of Credit, in either case in an amount sufficient to reduce the amount of the
Total Revolving Credit Outstandings to the amount of the Borrowing Base.

            (d)        If the total Revolving Credit Commitments of all of the
Lenders on any date should be less than the Total Revolving Credit Outstandings
on such date, whether as a result of the Company’s election to decrease the
amount of the Revolving Credit Commitments of the Lenders pursuant to Section
2.01(e) or otherwise, the Company shall be automatically required (without
demand or notice of any kind by the Agent or any Lender, all of which are hereby
expressly waived by the Company) to immediately repay the Revolving Credit Loans
and/or the Swing Line Loans and/or surrender for cancellation the outstanding
Letters of Credit, in either case in an amount sufficient to reduce the amount
of the Total Revolving Credit Outstandings to an amount equal to or less than
the total Revolving Credit Commitments of all of the Lenders.

            (e)        The Company may, upon three (3) Business Days' prior
written notice to the Agent and each Lender, terminate entirely at any time, or
proportionately reduce from time to time on a pro rata basis among the Lenders
based on their respective Pro Rata Shares by an aggregate amount of
$1,000,000.00 or any larger multiple of $250,000.00 the unused portions of the
Revolving Credit Commitments; provided, however, that (i) at no time shall the
Revolving Credit Commitments be reduced to a figure less than the Total
Revolving Credit Outstandings, (ii) at no time shall the Revolving Credit
Commitments be reduced to less than $10,000,000.00 and (iii) any such
termination or reduction shall be permanent and the Company shall have no right
to thereafter reinstate or increase, as the case may be, the Revolving Credit
Commitment of any Lender.”

continuing (provided, however, that U.S. Bank shall have no liability to any
other Lender for making a Swing Line Loan to the Company after the occurrence or
during the continuance of any Default or Event of Default unless U.S. Bank has
previously received notice in writing from the Company or any other Lender of,
or has actual knowledge of, the occurrence of such Default or Event of Default),
during the Revolving Credit Period, U.S. Bank  agrees to make such loans to the
Company (individually, a "Swing Line Loan" and collectively, the "Swing Line
Loans") as the Company may from time to time request pursuant to Section 2.04.
Each Swing Line Loan requested by way of a Notice of Swing Line Borrowing shall
be for an aggregate principal amount of at least $100,000.00 or any larger
multiple of $25,000.00. The aggregate principal amount of Swing Line Loans which
U.S. Bank shall be required or permitted to have outstanding under this
Agreement as of any date shall not exceed the amount of the Swing Line
Commitment; provided, however, that in no event shall the Total Revolving Credit
Outstandings as of any date exceed the sum of (i) the lesser of (A) total
Revolving Credit Commitments of all of the Lenders as of such date or (B) the
Borrowing Base as of such date.Within the foregoing limits, the Company may
borrow under this Section 2.01A, prepay under Section 2.11 and reborrow at any
time during the Revolving Credit Period under this Section 2.01A.  All Swing
Line Loans not paid prior to the last day of the Revolving Credit Period,
together with all accrued and unpaid interest thereon and all fees and other
amounts owing by the Company to U.S. Bank with respect thereto, shall be due and
payable on the last day of the Revolving Credit Period. Immediately upon the
making of a Swing Line Loan, each Lender (other than U.S. Bank) shall be deemed
to, and hereby irrevocably and unconditionally agrees to, purchase from U.S.
Bank a risk participation in such Swing Line Loan in an amount equal to such
Lender's Pro Rata Share (based on such Lender’s Pro Rata Share of the Revolving
Credit Commitments) of such Swing Line Loan.

            (b)        U.S. Bank may at any time in its sole and absolute
discretion request, on behalf of  the Company (and the Company hereby
irrevocably requests and authorizes U.S. Bank to so request on its behalf), that
each Lender make a Revolving Credit Base Rate Loan in an amount equal to such
Lender's Pro Rata Share of the amount of Swing Line Loans then outstanding. 
Such request shall (i) be made in writing (which written request shall be deemed
to be a Notice of Revolving Credit Borrowing for purposes hereof) and in
accordance with the requirements of Section 2.04(a), (ii) not be subject to the
minimum and multiples specified in Section 2.01(a) for the principal amount of
the Revolving Credit Base Rate Loans and (iii) be subject to the conditions set
forth in Section 3. U.S. Bank shall furnish the Company with a copy of the
applicable Notice of Revolving Credit Borrowing promptly after delivering such
notice to the Agent.  Each Lender shall make an amount equal to its Pro Rata
Share of the amount specified in such Notice of Revolving Credit Borrowing
available in immediately available funds to the Agent for the account of U.S.
Bank at the Agent’s address specified in or pursuant to Section 8.07 not later
than 12:00 noon (St. Louis, Missouri time) on the day specified in such Notice
of Revolving Credit Borrowing, whereupon, subject to Section 2.01A(c), each
Lender that so makes funds available shall be deemed to have made a Revolving
Credit Base Rate Loan to the Company in such amount. The Agent shall remit the
funds so received to U.S. Bank.

            (c)        If for any reason any Swing Line Loan cannot be
refinanced by such a borrowing of Revolving Credit Base Rate Loans in accordance
with Section 2.01A(b) (whether as a result of a failure to satisfy one or more
of the conditions set forth in Section 3 or otherwise), the request for a
Revolving Credit Base Rate Loan submitted by U.S. Bank as set forth herein shall
be deemed to be a request by U.S. Bank that each of the other Lenders fund its
risk participation in the relevant Swing Line Loan(s) and each such Lender's
payment to the Agent for the account of U.S. Bank pursuant to Section 2.01A(b)
shall be deemed payment in respect of such participation.

            (d)        If any Lender fails to make available to U.S. Bank any
amount required to be paid by such Lender pursuant to the foregoing provisions
of this Section 2.01A by the time specified in Section 2.01A(b), U.S. Bank shall
be entitled to recover from such Lender, on demand, such amount with interest
thereon for the period from the date such payment is required to the date on
which such payment is immediately available to U.S. Bank at a rate per annum
equal to the Fed Funds Rate. A certificate of U.S. Bank submitted to any Lender
with respect to any amounts owing under this Section 2.01A shall be conclusive
absent demonstrable error.

            (e)        Each Lender's obligation to make Revolving Credit Base
Rate Loans or to purchase and fund risk participations in Swing Line Loans
pursuant to this Section 2.01A shall be absolute and unconditional and shall not
be affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right that such Lender may have against U.S. Bank,
the Company or any other Person for any reason whatsoever, (ii) the occurrence
or continuance of a Default or Event of Default or (iii) any other occurrence,
event or condition, whether or not similar to any of the foregoing; provided,
however, that each Lender's obligation to make Revolving Credit Base Rate Loans
pursuant to this Section 2.01A (but not such Lender’s obligation to purchase and
fund risk participations in Swing Line Loans pursuant to this Section 2.01A) is
subject to the conditions set forth in Section 3. No such purchase or funding of
risk participations shall relieve or otherwise impair the obligation of the
Company to repay Swing Line Loans, together with interest as provided herein.

            (f)         At any time after any Lender has purchased and funded a
risk participation in a Swing Line Loan, if U.S. Bank receives any payment on
account of such Swing Line Loan, U.S. Bank will distribute to such Lender its
Pro Rata Share of such payment (appropriately adjusted, in the case of interest
payments, to reflect the period of time during which such Lender's risk
participation was funded) in the same funds as those received by U.S. Bank.

            (g)        If any payment received by U.S. Bank in respect of
principal or interest on any Swing Line Loan is required to be returned by U.S.
Bank to the Company or any other Person for any reason, each Lender shall pay to
U.S. Bank its Pro Rata Share thereof on the demand of U.S. Bank, plus interest
thereon from the date of such demand to the date such amount is returned, at a
rate per annum equal to the Fed Funds Rate.

(h)        Until a Lender funds its Revolving Credit Base Rate Loans or risk
participation pursuant to this Section 2.01A to refinance such Lender's Pro Rata
Share of any Swing Line Loan, interest in respect of such Pro Rata Share shall
be solely for the account of U.S. Bank.

            (i)         The Company shall make all payments of principal and
interest in respect of the Swing Line Loans directly to U.S. Bank.”

            30.       Section 2.02 of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “2.02    Term Loan. The Lenders have heretofore made LaBarge
Electronics a term loan in the aggregate original principal amount of
$25,000,000.00 (the "Term Loan"). As of October 3, 2008, the outstanding
principal balance of the Term Loan is $3,000,000.00. LaBarge Electronics desires
to borrow an additional aggregate principal amount of $7,000,000.00 from the
Lenders, thereby increasing the aggregate outstanding principal amount of the
Term Loan from $3,000,000.00 to $10,000,000.00. LaBarge Electronics shall borrow
(a) $3,500,000.00 of such additional principal amount on October 3, 2008, and
(b) the remaining $3,500,000.00 of such additional principal amount on November
30, 2008, or on such earlier Business Day during the period commencing October
3, 2008, and ending November 30, 2008, as LaBarge Electronics may elect upon not
less than three (3) Business Days’ prior written notice to the Agent (the
“Additional Term Loan Advance Date”). Subject to the terms and conditions set
forth in this Agreement, and so long as no Default or Event of Default has
occurred and is continuing, each Lender severally agrees to make an additional
advance on the Term Loan to LaBarge Electronics (a) on October 3, 2008, in a
principal amount equal to such Lender’s Pro Rata Share of $3,500,000.00 and (b)
on the Additional Term Loan Advance Date in a principal amount equal to such
Lender’s Pro Rata Share of $3,500,000.00. The Term Loan shall mature on October
3, 2010. Principal on the Term Loan shall be due and payable in nine (9)
consecutive quarterly installments as follows: eight (8) equal consecutive
quarterly installments in the amount of $500,000.00 each, due and payable on the
last day of each November, February, May and August commencing November 30,
2008, with the ninth (9th) and final installment in the amount of the then
outstanding principal balance of the Term Loan due and payable on October 3,
2010. All principal payments and prepayments on the Term Loan shall, unless
otherwise directed by LaBarge Electronics in writing at or prior to the time of
such payment or prepayment, be applied first to that portion of the Term Loan,
if any, accruing interest based on the Adjusted Base Rate and then to those
portions of the Term Loan, if any, accruing interest based on the LIBOR Rate
(and among those portions of the Term Loan, if any, accruing interest based on
the LIBOR Rate, being applied to the Interest Periods in the order of their
respective expiration dates (i.e. earliest expiration date first)).”

            31.       Section 2.04(a) of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “(a)      The Company shall give notice (a "Notice of Revolving
Credit Borrowing") to the Agent by 12:00 noon (St. Louis time) on the Business
Day of each Revolving Credit Base Rate Loan to be made to the Company, and by
12:00 noon (St. Louis Time) at least two (2) Eurodollar Business Days before
each Revolving Credit LIBOR Loan to be made to the Company, specifying:

                        (i)         the date of such Revolving Credit Loan,
which shall be a Business Day during the Revolving Credit Period in the case of
a Revolving Credit Base Rate Loan and a Eurodollar Business Day during the
Revolving Credit Period in the case of a Revolving Credit LIBOR Loan,

                        (ii)        the aggregate principal amount of such
Revolving Credit Loan,

                        (iii)       whether such Revolving Credit Loan is to be
a Revolving Credit Base Rate Loan or a Revolving Credit LIBOR Loan, and

                        (iv)       in the case of a Revolving Credit LIBOR Loan,
the duration of the initial Interest Period applicable thereto, subject to the
provisions of the definition of Interest Period.”

            32.       Section 2.04(d) of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “(d)      The Company hereby irrevocably authorizes the Agent and
each Lender to rely on telephonic, facsimile, telegraphic, telex or written
instructions of any person identifying himself or herself as one of the
individuals listed on Schedule 2.04 attached hereto (or any other individual
from time to time authorized to act on behalf of the Company pursuant to a
resolution adopted by the Board of Directors of the Company and certified by the
Secretary of the Company and delivered to the Agent and each Lender) (each, an
“Authorized Person”) with respect to any request to make a Revolving Credit Loan
or a Swing Line Loan or a repayment hereunder, and on any signature which the
Agent or such Lender, as the case may be, believes in good faith to be genuine,
and the Company shall be bound thereby in the same manner as if such individual
were actually authorized or such signature were genuine.  The Company also
hereby agrees to defend and indemnify the Agent and each Lender and hold the
Agent and each Lender harmless from and against any and all claims, demands,
damages, liabilities, losses, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses) relating to or arising out of or in
connection with the acceptance of any notices or instructions believed by the
Agent or such Lender, as the case may be, in good faith to have been sent or
delivered by an Authorized Person, regardless of whether such notice or
instruction was in fact delivered by an Authorized Person.”

            33.       The following new Sections 2.04(e) and 2.04(f) are hereby
added to the Loan Agreement:

“(e)      Except as set forth in this Section 2.04(e), the Company shall give
notice (a "Notice of Swing Line Borrowing") to U.S. Bank by 12:00 noon (St.
Louis time) on the Business Day of each Swing Line Loan, specifying:

            (i)         the date of such Swing Line Loan, which must be a
Business Day during the Revolving Credit Period; and

            (ii)        the principal amount of such Swing Line Loan.

A Notice of Swing Line Borrowing shall not be revocable by the Company.

Pursuant to a certain U.S. Bank Treasury Management Service Agreement by and
between the Company and U.S. Bank and any and all other terms and conditions,
agreements, documents and/or instruments related thereto, as the same may from
time to time be amended, modified, restated or replaced, the Company has
requested and authorized U.S. Bank to (A) to apply any collected balances (after
funding advances) in excess of a mutually predetermined amount (the “Target
Balance”) remaining at the end of any day in the Company’s Account No.
4349567042 at U.S. Bank (the “Company’s Operating Account”) to the repayment of
any outstanding Swing Line Loans and (B) subject to all of the other terms and
conditions of this Agreement (including the preconditions to Loans set forth in
Section 3.02), make a Swing Line Loan to the Company at the end of any day on
which the Company shall have an overdraft (negative collected balance) or a
collected balance otherwise less than the Target Balance in the Company’s
Operating Account (a “Deficiency Amount”) after crediting all deposits received
in immediately available funds and debiting all withdrawals made and checks
presented against the Company’s Operating Account and honored by U.S. Bank as of
such date, which Swing Line Loan shall be in the amount of the Deficiency
Amount, without any other request or authorization therefor from the Company and
without notice to the Company.  A Notice of Swing Line Borrowing shall not be
required in connection with a Swing Line Loan made to cover any Deficiency
Amount in the Company’s Operating Account as set forth in the immediately
preceding sentence.

            (f)         Unless U.S. Bank determines that any applicable
condition specified in Section 3 has not been satisfied, U.S. Bank will make the
proceeds of each Swing Line Loan available to the Company by 3:00 p.m. (St.
Louis time) by crediting such funds to the Company’s Operating Account.”

            34.       Section 2.05(b) of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “(b)      The Term Loan of each Lender to LaBarge Electronics shall
be evidenced by a Term Loan Promissory Note of LaBarge Electronics payable to
the order of such Lender in an original principal amount equal to the amount of
such Lender's Pro Rata Share of $10,000,000.00, each of which Term Loan
Promissory Notes shall be in substantially the form of Exhibit C attached hereto
and incorporated herein by reference (with appropriate insertions)(collectively,
as the same may from time to time be amended, modified, extended, renewed,
restated or replaced (including, without limitation, any Term Loan Note issued
in full or partial replacement of an existing Term Loan Note as a result of an
assignment by a Lender), the "Term Loan Notes").”

            35.       The following new Sections 2.05(e) and 2.05(f) are hereby
added to the Loan Agreement:

             “(e)      The Swing Line Loans of U.S. Bank to the Company shall be
evidenced by a Swing Line Note of the Company payable to the order of U.S. Bank
in a principal amount equal to the amount of the Swing Line Commitment, which
Swing Line Note shall be in substantially the form of Exhibit I attached hereto
and incorporated herein by reference (with appropriate insertions) (as the same
may from time to time be amended, modified extended, renewed or restated, the
"Swing Line Note").

            (f)         U.S. Bank shall record in its books and records the date
and amount of each Swing Line Loan made by it and the date and amount of each
payment of principal and/or interest made by the Company with respect thereto;
provided, however, that the obligation of the Company to repay each Swing Line
Loan actually made by U.S. Bank to the Company under this Agreement shall be
absolute and unconditional, notwithstanding any failure of U.S. Bank to make any
such recordation or any mistake by U.S. Bank in connection with any such
recordation. The books and records of U.S. Bank showing the account between U.S.
Bank and the Company shall be conclusive evidence of the items set forth therein
in the absence of demonstrable error.”

            36.       Section 2.06 of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “2.06    Duration of Interest Periods and Selection of Interest
Rates.

            (a)        The duration of the initial Interest Period for each
Revolving Credit LIBOR Loan shall be as specified in the applicable Notice of
Revolving Credit Borrowing.  The Company shall elect the duration of each
subsequent Interest Period applicable to such Revolving Credit LIBOR Loan and
the interest rate to be applicable during such subsequent Interest Period (and
the Company shall have the option (i) in the case of any Revolving Credit Base
Rate Loan, to elect that such Revolving Credit Loan become a Revolving Credit
LIBOR Loan and the Interest Period to be applicable thereto, and (ii) in the
case of any Revolving Credit LIBOR Loan, to elect that such Revolving Credit
Loan become a Revolving Credit Base Rate Loan), by giving oral or written notice
of such election to the Agent by 12:00 noon (St. Louis time) on the Business Day
of, in the case of the election of the Adjusted Base Rate, and by 12:00 noon
(St. Louis time) at least two (2) Eurodollar Business Days before, in the case
of the election of the LIBOR Rate, the end of the immediately preceding Interest
Period applicable thereto, if any; provided, however, that notwithstanding the
foregoing, in addition to and without limiting the rights and remedies of the
Agent and the Lenders under Section 6 hereof, so long as any Default or Event of
Default under this Agreement has occurred and is continuing, the Company shall
not be permitted to renew any Revolving Credit LIBOR Loan as a Revolving Credit
LIBOR Loan or to convert any Revolving Credit Base Rate Loan into a Revolving
Credit LIBOR Loan.  Upon receipt of any such notice given by Borrower to the
Agent under this Section 2.06(a), the Agent shall notify each Lender by 1:00
p.m. (St. Louis time) on the date of receipt of such notice (which must be a
Business Day) of the contents thereof.  If the Agent does not receive a notice
of election for a Revolving Credit Loan pursuant to this Section 2.06(a) within
the applicable time limits specified herein, the Company shall be deemed to have
elected to pay such Revolving Credit Loan in whole pursuant to Section 2.11 on
the last day of the current Interest Period with respect thereto and to reborrow
the principal amount of such Revolving Credit Loan on such date as a Revolving
Credit Base Rate Loan.

            (b)        The Term Loan shall bear interest on the outstanding
principal amount thereof at a rate per annum equal to the Adjusted Base Rate. 
LaBarge Electronics may from time to time fix the interest rate on all or any
portion of the Term Loan in an amount not less than $500,000.00 or any larger
multiple of $250,000.00 at the LIBOR Rate for the Interest Period selected by
LaBarge Electronics (subject to the definition of Interest Period); provided,
however, that notwithstanding the foregoing, in addition to and without limiting
the rights and remedies of the Agent and the Lenders under Section 6 hereof, so
long as any Default or Event of Default under this Agreement has occurred and is
continuing, LaBarge Electronics shall not be permitted to fix the interest rate
on all or any portion of the Term Loan at the LIBOR Rate.  If LaBarge
Electronics elects to have any portion of the Term Loan bear interest at the
LIBOR Rate, LaBarge Electronics shall give oral or written notice (an "Interest
Rate Selection Notice") to the Agent by 12:00 noon (St. Louis time) at least two
(2) Eurodollar Business Days before any date (which must be a Eurodollar
Business Day) upon which LaBarge Electronics desires to fix the interest rate on
any portion of the Term Loan, which Interest Rate Selection Notice shall specify
the portion of the Term Loan which is to bear interest at the LIBOR Rate and the
initial Interest Period applicable thereto.  LaBarge Electronics may not revoke
or rescind any Interest Rate Selection Notice.  Upon receipt of any such
Interest Rate Selection Notice given by LaBarge Electronics to the Agent under
this Section 2.06(b), the Agent shall notify each Lender by 1:00 p.m. (St. Louis
time) on the date of receipt of such Interest Rate Selection Notice (which must
be a Business Day) of the contents thereof.  Unless LaBarge Electronics shall
have otherwise notified the Agent in accordance with this Section 2.06(b), upon
the expiration of any Interest Period, that portion of the Term Loan bearing
interest at the LIBOR Rate during such Interest Period shall bear interest at
the Adjusted Base Rate from and after the expiration of such Interest Period.

            (c)        The Company and LaBarge Electronics, collectively, may
not have outstanding and the Lenders shall not be obligated to make more than
ten (10) LIBOR Loans at any one time.”

            37.       Section 2.07(e) of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “(e)      So long as no Event of Default has occurred and is
continuing, the from time to time outstanding principal balance of each Swing
Line Loan shall bear interest prior to the maturity of the Swing Line Note
(whether by reason of acceleration or otherwise) at a rate per annum equal to
the Adjusted Base Rate. So long as any Event of Default has occurred and is
continuing, the from time to time outstanding principal balance of each Swing
Line Loan shall, unless otherwise agreed in writing by each Lender, bear
interest prior to the maturity of the Swing Line Note (whether by reason of
acceleration or otherwise) at a rate per annum equal to Three Percent (3%) per
annum over and above the Adjusted Base Rate. Such interest shall be due and
payable monthly on the last day of each month, commencing on the first such date
after such Swing Line Loan is made, and at the maturity of the Swing Line Note
(whether by reason of acceleration or otherwise). From and after the maturity of
the Swing Line Note (whether by reason of acceleration or otherwise), the from
time to time outstanding principal balance of each Swing Line Loan shall bear
interest at a rate per annum equal to Three Percent (3%) per annum over and
above the Adjusted Base Rate and be due and payable on demand.

            (f)         The Agent shall determine each interest rate applicable
to the Loans hereunder and its determination thereof shall be conclusive in the
absence of demonstrable error.”

            38.       Section 2.09 of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “2.09    Fees.

            (a)        From and including the date of this Agreement to but
excluding the last day of the Revolving Credit Period, the Company shall pay to
the Agent for the account of each Lender a nonrefundable commitment fee on the
unused portion of the Revolving Credit Commitment of such Lender (determined by
subtracting such Lender's Pro Rata Share of the Total Revolving Credit
Outstandings from such Lender's Revolving Credit Commitment) at a rate per annum
equal to the Applicable Commitment Fee Rate. Said commitment fee shall be (i)
calculated on a daily basis, (ii) payable quarterly in arrears on each March 31,
June 30, September 30 and December 31 during the Revolving Credit Period and on
the last day of the Revolving Credit Period and (iii) calculated on an actual
day, 360‑day year basis.

            (b)        From and including October 3, 2008, to but excluding the
Additional Term Loan Advance Date, LaBarge Electronics shall pay to the Agent
for the ratable account of the Lenders a nonrefundable commitment fee on the
amount by which the aggregate outstanding principal balance of the Term Loan is
less than $10,000,000.00 at a rate per annum equal to the Applicable Commitment
Fee Rate. Said commitment fee shall be (i) calculated on a daily basis, (ii)
payable in arrears on December 31, 2008, and (iii) calculated on an actual day,
360‑day year basis.

            (c)        The Company and LaBarge Electronics agree to pay U.S.
Bank certain fees in the amounts set forth in that certain letter agreement by
and between the Company and U.S. Bank dated July 23, 2008, as the same may from
time to time be amended, modified, extended, renewed or restated.”

            39.       The following new Section 2.11(e) is hereby added to the
Loan Agreement:

be a Business Day) specifying that it is prepaying the Swing Line Loans, prepay
without penalty or premium the Swing Line Loans in whole at any time or in part
from time to time, by paying the principal amount to be paid. Any such notice
from the Borrower shall not be revocable.”

            40.       Section 2.13 of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “2.13    General Provisions as to Payments. Each Borrower shall make
each payment of principal of, and interest on, the Loans to such Borrower and of
fees and all other amounts payable by such Borrower under this Agreement, not
later than 2:00 p.m. (St. Louis time) on the date when due and payable, in
Federal or other immediately available funds, to the Agent (or, in the case of
Swing Line Loans, to U.S. Bank) at its address referred to in Section 8.07. All
payments received by the Agent or U.S. Bank after 2:00 p.m. (St. Louis time)
shall be deemed to have been received by the Agent or U.S. Bank, as the case may
be, on the next succeeding Business Day. The Agent will distribute to each
Lender in immediately available funds its Pro Rata Share of each such payment
received by the Agent for the account of the Lenders by 3:00 p.m. (St. Louis
time) on the day of receipt of such payment by the Agent if such payment is
received by the Agent from the applicable Borrower by 2:00 p.m. (St. Louis time)
on such day or by 12:00 noon (St. Louis time) on the next succeeding Business
Day if such payment is received by the Agent from the applicable Borrower after
2:00 p.m. (St. Louis time) on such day. Any such payment owed by the Agent to
any Lender which is not paid within the applicable time period shall bear
interest (payable by the Agent) until paid at the Fed Funds Rate. Whenever any
payment of principal of, or interest on, the Loans or of fees shall be due on a
day which is not a Business Day, the date for payment thereof shall be extended
to the next succeeding Business Day. If the date for any payment of principal is
extended by operation of law or otherwise, interest thereon, at the then
applicable rate, shall be payable for such extended time.”

            41.       Section 2.23 of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

            “2.23    Application of Payments. Notwithstanding any provision
contained in this Agreement and/or any other Transaction Document to the
contrary:

            (a)        so long as neither the Agent nor the Required Lenders
have accelerated and demanded immediate repayment of any or all of the
Borrower's Obligations owed by any one or more of the Borrowers following an
Event of Default under this Agreement, all monies received by the Agent and/or
any Lender as a result of voluntary payment from a Borrower shall be applied to
the payment of the various Borrower's Obligations owed by such Borrower as
directed by such Borrower and the Agent shall promptly remit to each Lender its
ratable share of each such payment; and

            (b)        all other monies received by the Agent and/or any Lender,
including, without limitation, all monies received by the Agent and/or any
Lender after the Agent or the Required Lenders have accelerated and demanded
immediate repayment of any or all of the Borrower's Obligations owed by any one
or more of the Borrowers following an Event of Default under this Agreement,
whether received as a result of a payment from any Borrower and/or any other
Obligor, through the exercise of a right of setoff or realized from the sale or
other disposition of or collections from any of the Collateral or resulting from
any proceedings against any Borrower or any other Obligor or from any source
whatsoever, shall be applied in the following order (or in such other order as
each of the Lenders may agree): (i) first, to the reasonable costs and expenses,
including reasonable attorneys' fees and expenses, incurred by the Agent and/or
any Lender to effect such recovery, to enforce any right or remedy under this
Agreement, any other Transaction Document or any other agreement with any
Borrower or any Person relating to such recovery, to dispose of any of the
Collateral, to preserve or protect any of the Collateral, including, without
limitation, making expenditures for taxes, insurance premiums, prevention of
waste and preservation of any of the Collateral, repairs and maintenance, or to
manage and operate any of the Collateral; and (ii) second, pro rata among the
various the Borrower’s Obligations owed by any one or more of the Borrowers
based on the then total outstanding amount of each of said Borrower's
Obligations on the date of receipt of such monies. For example, if, as of the

interest) of the Revolving Credit Loans was $300.00, (ii) the aggregate
outstanding principal amount of the Swing Line Loans was $50.00, (iii) the

outstanding principal amount of the Term Loan was $400.00, (v) the Swap
Termination Value owed by a Borrower to a Lender with respect to a Swap Contract
was $75.00 and (vi) the amount owed by a Borrower to a Lender under or with
respect to a Treasury Management Agreement was $25.00, Thirty Percent (30%) of
the monies would be applied to the Revolving Credit Loans, Five Percent (5%) of
the monies would be applied to the Swing Line Loans, Fifteen Percent (15%) of
the monies would be applied to the Letters of Credit, Forty Percent (40%) of the
monies would be applied to the Term Loan, Seven and One-Half Percent (7-1/2%) of
the monies would be applied to the Swap Termination Value under the Swap
Contract and Two and One-Half Percent (2-1/2%) of the monies would be applied to
the amounts under or with respect to a Treasury Management Agreement; and any
amount so allocated to a Letter of Credit shall be held in escrow by the Agent
as cash collateral for the Company’s reimbursement and other obligations with
respect to such Letter of Credit until such Letter of Credit is drawn on,
expires or is terminated, and, to the extent such Letter of Credit is not fully
drawn, the excess monies escrowed for such Letter of Credit shall be reallocated
among the other Borrower’s Obligations owed by any one or more of the Borrowers
in such amounts as would have been allocated to such other Borrower’s
Obligations (in the manner set forth above) if the undrawn portion of such
Letter of Credit had not been deemed to be issued and outstanding for purposes
of the allocation which gave rise to the escrow deposit); and any amount so
allocated to the various the Borrower’s Obligations shall be allocated among the
Lenders based on their respective ratable shares of such Borrower’s
Obligations.”

Agreement, Lender's obligation to make additional Revolving Credit Loans under
this Note may be terminated in the manner and with the effect as provided in the
Loan Agreement and the entire outstanding principal balance of this Note and all
accrued and unpaid interest thereon may be declared to be immediately due and
payable in the manner and with the effect as provided in the Loan Agreement.

            In the event that any payment due under this Note shall not be paid
when due, whether by reason of maturity, acceleration or otherwise, and this
