Commitment then in effect (notwithstanding that the Swingline Loans outstanding
at any time, when aggregated with the Swingline Lender's other outstanding
Revolving Loans, may exceed the Swingline Commitment then in effect) and (ii)
the Borrowers shall not request, and the Swingline Lender shall not make, any
Swingline Loan if, after giving effect to the making of such Swingline Loan, the
aggregate amount of the Available Revolving Commitments would be less than zero.
During the Revolving Commitment Period, the Borrowers may use the Swingline
Commitment by borrowing, repaying and reborrowing, all in accordance with the
terms and conditions hereof. All Swingline Loans shall bear interest at a rate
per annum equal to the Federal Funds Rate plus the Applicable Margin for
Eurocurrency Loans.

     (b) A Borrower shall repay to the Swingline Lender the then unpaid
principal amount of each Swingline Loan on the earlier of the Revolving
Termination Date and the first date after such Swingline Loan is made that is
the 15th or last day of a calendar month and is at least two Business Days after

                                                                              18

such Swingline Loan is made; provided that on each date that a Revolving Loan is
                             --------
borrowed, such Borrower shall repay all Swingline Loans then outstanding.

     2.4   Procedure for Swingline Borrowing; Refunding of Swingline Loans. (a)
           ---------------------------------------------------------------
Whenever a Borrower desires that the Swingline Lender make Swingline Loans it
shall give the Swingline Lender irrevocable telephonic notice confirmed promptly
in writing (which telephonic notice must be received by the Swingline Lender not
later than 1:00 P.M., New York City time, on the proposed Borrowing Date),
specifying (i) the amount to be borrowed and (ii) the requested Borrowing Date
(which shall be a Business Day during the Revolving Commitment Period). Each
borrowing under the Swingline Commitment shall be in an amount equal to $500,000
or a whole multiple of $100,000 in excess thereof. Not later than 3:00 P.M., New
York City time, on the Borrowing Date specified in a notice in respect of
Swingline Loans, the Swingline Lender shall make available to the Administrative
Agent at the Funding Office an amount in immediately available funds equal to
the amount of the Swingline Loan to be made by the Swingline Lender. The
Administrative Agent shall make the proceeds of such Swingline Loan available to
such Borrower on such Borrowing Date by depositing such proceeds in the account
of such Borrower with the Administrative Agent on such Borrowing Date in
immediately available funds.

     (b) The Swingline Lender, at any time and from time to time in its sole and
absolute discretion may, on behalf of the Borrowers (which hereby irrevocably
direct the Swingline Lender to act on their behalf), on one Business Day's
notice given by the Swingline Lender no later than 12:00 Noon, New York City
time, request each Revolving Lender to make, and each Revolving Lender hereby
agrees to make, a Revolving Loan, in an amount equal to such Revolving Lender's
Revolving Percentage of the aggregate amount of the Swingline Loans (the
"Refunded Swingline Loans") outstanding on the date of such notice, to repay the
 ------------------------
Swingline Lender. Each Revolving Lender shall make the amount of such Revolving
Loan available to the Administrative Agent at the Funding Office in immediately
available funds, not later than 10:00 A.M., New York City time, one Business Day
after the date of such notice. The proceeds of such Revolving Loans shall be
immediately made available by the Administrative Agent to the Swingline Lender
for application by the Swingline Lender to the repayment of the Refunded
Swingline Loans. The Borrowers irrevocably authorize the Swingline Lender to
charge the relevant Borrower's account with the Administrative Agent (up to the
amount available in each such account) in order to immediately pay the amount of
such Refunded Swingline Loans to the extent amounts received from the Revolving
Lenders are not sufficient to repay in full such Refunded Swingline Loans.

     (c) If prior to the time a Revolving Loan would have otherwise been made
pursuant to Section 2.4(b), one of the events described in Section 8(f) shall
have occurred and be continuing with respect to a Borrower or if for any other
reason, as determined by the Swingline Lender in its sole discretion, Revolving
Loans may not be made as contemplated by Section 2.4(b), each Revolving Lender
shall, on the date such Revolving Loan was to have been made pursuant to the
notice referred to in Section 2.4(b), purchase for cash an undivided
participating interest in the then outstanding Swingline Loans by paying to the
Swingline Lender an amount (the "Swingline Participation Amount") equal to (i)
                                 ------------------------------
such Revolving Lender's Revolving Percentage times (ii) the sum of the aggregate
                                             -----
principal amount of Swingline Loans then outstanding that were to have been
repaid with such Revolving Loans.

     (d) Whenever, at any time after the Swingline Lender has received from any
Revolving Lender such Lender's Swingline Participation Amount, the Swingline
Lender receives any payment on account of the Swingline Loans, the Swingline
Lender will distribute to such Lender its Swingline Participation Amount
(appropriately adjusted, in the case of interest payments, to reflect the period
of time during which such Lender's participating interest was outstanding and
funded and, in the case of principal and interest payments, to reflect such
Lender's pro rata portion of such payment if such payment is not sufficient to
         --- ----
pay the principal of and interest on all Swingline Loans then due); provided,
                                                                    --------
however, that in the event that such payment received by the Swingline Lender is
-------
required to be returned, such

<PAGE>
                                                                              19

Revolving Lender will return to the Swingline Lender any portion thereof
previously distributed to it by the Swingline Lender.

     (e) Each Revolving Lender's obligation to make the Loans referred to in
Section 2.4(b) and to purchase participating interests pursuant to Section
2.4(c) shall be absolute and unconditional and shall not be affected by any
circumstance, including (i) any setoff, counterclaim, recoupment, defense or
other right that such Revolving Lender or such Borrower may have against the
Swingline Lender, such Borrower or any other Person for any reason whatsoever,
(ii) the occurrence or continuance of a Default or an Event of Default or the
failure to satisfy any of the other conditions specified in Section 5, (iii) any
adverse change in the condition (financial or otherwise) of such Borrower, (iv)
any breach of this Agreement or any other Loan Document by such Borrower, any
other Loan Party or any other Revolving Lender or (v) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.

     2.5   Facility Fees, etc. (a) Aeroflex agrees to pay to the Administrative
           ------------------
Agent for the account of each Revolving Lender a facility fee in Dollars for the
period from and including the date hereof to the last day of the Revolving
Commitment Period, computed at the Facility Fee Rate on the average daily amount
of the Revolving Commitment of such Lender (whether used or unused) during the
period for which payment is made, payable quarterly in arrears on each Fee
Payment Date, commencing on the first such date to occur after the date hereof.

     (b) Aeroflex agrees to pay to the Administrative Agent the fees in the
amounts and on the dates as set forth in any fee agreements with the
Administrative Agent and to perform any other obligations contained therein.

     2.6   Termination or Reduction of Revolving Commitments. Aeroflex shall
           -------------------------------------------------
have the right, upon not less than three Business Days' notice to the
Administrative Agent, to terminate the Revolving Commitments or, from time to
time, to reduce the amount of the Revolving Commitments; provided that no such
termination or reduction of Revolving Commitments shall be permitted if, after
giving effect thereto and to any prepayments of the Revolving Loans and
Swingline Loans made on the effective date thereof, the Total Revolving
Extensions of Credit would exceed the Total Revolving Commitments. Any such
reduction shall be in an amount equal to $1,000,000, or a whole multiple
thereof, and shall reduce permanently the Revolving Commitments then in effect.

     2.7   Additional Revolving Commitments. Subject to the consent of the
           --------------------------------
Administrative Agent, the Issuing Lender and the Swingline Lender, Aeroflex may
request at any time and from time to time that the existing Revolving Lenders
increase their respective Revolving Commitments and/or that additional Lenders
be added to this Agreement until such time as the Total Revolving Commitments
are equal to $150,000,000; provided, that (i) the amount of any Lender's
increase in its Revolving Commitment shall be at least $5,000,000, (ii) at the
time of the relevant request, that no Default or Event of Default shall have
occurred and be continuing or shall result from the proposed increase and (iii)
the representations and warranties of Aeroflex shall continue to be accurate in
all material respects. The Borrowers shall (x) first, offer the existing Lenders
the opportunity to participate in a pro rata increase of their respective
Revolving Commitments and (y) second, offer one or more additional banks,
financial institutions or other entities (approved by the Administrative Agent,
such approval not to be unreasonably withheld) the opportunity to participate in
all or a portion of such proposed increase. Schedule 1.1(b) shall be
automatically amended to reflect any existing Revolving Lender's increased
Revolving Commitment. By its signature of a confirmation of its increased or
additional Revolving Commitment in a form satisfactory to Aeroflex and the
Administrative Agent (and subsequent to its delivery of a completed or revised
Administrative Questionnaire to the Administrative Agent), each increasing or
additional Revolving Lender shall be a "Revolving Lender" for all purposes

<PAGE>
                                                                              20

hereunder with its increased or additional Revolving Commitment and Schedule
1.1(b) shall be automatically amended to reflect such increasing or additional
Revolving Lender's new Revolving Commitment. Upon increasing its Revolving
Commitment or becoming a "Revolving Lender" hereunder, each Revolving Lender
shall automatically be responsible for its Revolving Percentage of the Aggregate
Exposure and, on one or more dates as set forth in an appropriate notice given
by the Administrative Agent to each of the existing and new or increasing
Revolving Lenders (which date or dates may be the last day or days of the
current Interest Periods), shall pay to the Administrative Agent its Revolving
Percentage of the Revolving Loans or certain of them (with interest rates
applicable thereto as are agreed with the Borrowers) which shall then be applied
to prepay amounts outstanding to the other Revolving Lenders.

     2.8   Optional and Mandatory Prepayments. A Borrower may at any time and
           ----------------------------------
from time to time prepay the Loans, in whole or in part, without premium or
penalty, upon irrevocable notice delivered to the Administrative Agent no later
than 11:00 A.M., New York City time, three Business Days prior thereto, in the
case of Eurocurrency Loans, and no later than 11:00 A.M., New York City time,
one Business Day prior thereto, in the case of ABR Loans, which notice shall
specify the date and amount of prepayment and whether the prepayment is of
Eurocurrency Loans or ABR Loans; provided, that if a Eurocurrency Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, such Borrower shall also pay any amounts owing pursuant to Section
2.18. Upon receipt of any such notice the Administrative Agent shall promptly
notify each relevant Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified therein,
together with (except in the case of Revolving Loans that are ABR Loans and
Swingline Loans) accrued interest to such date on the amount prepaid. Partial
prepayments of Revolving Loans shall be in an aggregate principal amount of
$1,000,000 or a whole multiple thereof. Partial prepayments of Swingline Loans
shall be in an aggregate principal amount of $100,000 or a whole multiple
thereof. To the extent that at any time (by virtue of changes in the Exchange
Rate or otherwise) the aggregate principal amount of the Loans and Letters of
Credit outstanding shall exceed the Total Revolving Commitments then in effect,
the Borrowers shall make prompt repayment of the Loans to the extent of such
excess.

     2.9   Conversion and Continuation Options. (a) A Borrower may elect from
           -----------------------------------
time to time to convert Eurocurrency Loans to ABR Loans by giving the
Administrative Agent prior irrevocable notice of such election no later than
11:00 A.M., Local Time, on the third Business Day preceding the proposed
conversion date, provided that any such conversion of Eurocurrency Loans may
                 --------
only be made on the last day of an Interest Period with respect thereto. A
Borrower may elect from time to time to convert ABR Loans to Eurocurrency Loans
by giving the Administrative Agent prior irrevocable notice of such election no
later than 11:00 A.M., New York City time, on the third Business Day preceding
the proposed conversion date (which notice shall specify the length of the
initial Interest Period therefor), provided that no ABR Loan under the Facility
                                   --------
may be converted into a Eurocurrency Loan when any Event of Default has occurred
and is continuing and the Administrative Agent or the Required Lenders have
determined in its or their sole discretion not to permit such conversions. Upon
receipt of any such notice the Administrative Agent shall promptly notify each
relevant Lender thereof.

     (b) Any Eurocurrency Loan may be continued as such upon the expiration of
the then current Interest Period with respect thereto by such Borrower giving
irrevocable notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans, provided
                                                                       --------
that no Eurocurrency Loan under the Facility may be continued as such when any
Event of Default has occurred and is continuing and the Administrative Agent has
or the Required Lenders have determined in its or their sole discretion not to
permit such continuations, and provided, further, that if such Borrower shall
                               --------  -------
fail to give any required notice as described above in this paragraph such Loans
shall be automatically converted to Eurocurrency Loans with an Interest Period
of one month or if such continuation is not otherwise permitted pursuant to the
preceding proviso such Loans shall be automatically converted to ABR Loans, in
each case on the last day of such then expiring Interest Period. Upon receipt of
any such notice the Administrative Agent shall promptly notify each relevant
Lender thereof.

     2.10   Limitation on Certain Borrowings. Notwithstanding anything to the
            --------------------------------
contrary in this Agreement, the aggregate principal amount of the Loans of, and
Letters of Credit issued for the account of, Solutions, and the aggregate
principal amount of Loans and Letters of Credit outstanding in Optional
Currencies shall in each case be limited to the equivalent of $30,000,000, and
to the extent that at any time (by virtue of changes in the Exchange Rate or
otherwise) either such aggregate principal amount shall exceed $30,000,000, the
Borrowers shall promptly prepay Loans to the extent of such excess.

     2.11   Limitations on Eurocurrency Tranches. Notwithstanding anything to
            ------------------------------------
the contrary in this Agreement, all borrowings, conversions and continuations of
Eurocurrency Loans and all selections of Interest Periods shall be in such
amounts and be made pursuant to such elections so that, (a) after giving effect
thereto, the aggregate principal amount of the Eurocurrency Loans comprising
each Eurocurrency Tranche shall be equal to $2,000,000 or a whole multiple of
$1,000,000 in excess thereof, (b) no more than ten Eurocurrency Tranches shall
be outstanding at any one time, and (c) no more than the equivalent of
$30,000,000 of the Facility, in the aggregate, shall be available for borrowing
as Optional Currency Revolving Loans.

     2.12   Interest Rates and Payment Dates. (a) Each Eurocurrency Loan shall
            --------------------------------
bear interest for each day during each Interest Period with respect thereto at a
rate per annum equal to the Eurocurrency Rate determined for such day plus the
Applicable Margin.

     (b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR
plus the Applicable Margin.

     (c) (i) If all or a portion of the principal amount of any Loan or
Reimbursement Obligation shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), all outstanding Loans and Reimbursement
Obligations (whether or not overdue) shall bear interest at a rate per annum
equal to (x) in the case of the Loans, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this Section plus 2%
                                                                        ----
or (y) (1) in the case of Reimbursement Obligations in Dollars, the rate
applicable to ABR Loans under the Facility plus 2%, or (2) in the case of
                                           ----
Reimbursement Obligations in an Optional Currency, the overnight Eurocurrency
Rate for such Optional Currency plus the Applicable Margin plus 2%, and (ii) if
                                ----                       ----
all or a portion of any interest payable on any Loan or Reimbursement Obligation
or any facility fee or other amount payable hereunder shall not be paid when due
(whether at the stated maturity, by acceleration or otherwise), such overdue
amount shall bear interest at a rate per annum equal to the rate then applicable
to ABR Loans under the Facility plus 2% (in the case of overdue amounts in
                                ----
Dollars) or the overnight Eurocurrency Rate for the relevant Optional Currency
plus the Applicable Margin plus 2% (in the case of an overdue amount in an
----                       ----
Optional Currency), in each case, with respect to clauses (i) and (ii) above,
from the date of such non-payment until such amount is paid in full (as well
after as before judgment).

     (d) Interest shall be payable in arrears on each Interest Payment Date,
provided that interest accruing pursuant to paragraph (c) of this Section shall
--------
be payable from time to time on demand.

     2.13   Computation of Interest and Fees. (a) Interest and fees payable
            --------------------------------
pursuant hereto shall be calculated on the basis of a 360-day year for the
actual days elapsed, except that, with respect to ABR Loans the rate of interest
on which is calculated on the basis of the Prime Rate and for Eurocurrency Loans
denominated in British pounds sterling, the interest thereon shall be calculated
on the basis of a

<PAGE>
                                                                              21

365- (or 366-, as the case may be) day year for the actual days elapsed. The
Administrative Agent shall as soon as practicable notify the relevant Borrower
and the relevant Lenders of each determination of a Eurocurrency Rate. Any
change in the interest rate on a Loan resulting from a change in the ABR or the
Eurocurrency Reserve Requirements shall become effective as of the opening of
business on the day on which such change becomes effective. The Administrative
Agent shall as soon as practicable notify the relevant Borrower and the relevant
Lenders of the effective date and the amount of each such change in interest
rate.

     (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of a Borrower, deliver to such
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.13(a).

     2.14   Inability to Determine Interest Rate. If prior to the first day of
            ------------------------------------
any Interest Period the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the relevant Borrower) that,
by reason of circumstances affecting the relevant market, adequate and
reasonable means do not exist for ascertaining the Eurocurrency Rate for such
Interest Period, the Administrative Agent shall give telecopy or telephonic
notice thereof to the relevant Borrower and the relevant Lenders as soon as
practicable thereafter. If such notice is given (w) any Eurocurrency Loans in
Dollars under the Facility requested to be made on the first day of such
Interest Period shall be made as ABR Loans and any Eurocurrency Loans in an
Optional Currency so requested to be made shall not be made, (x) any Loans in
Dollars under the Facility that were to have been converted on the first day of
such Interest Period to Eurocurrency Loans shall be continued as ABR Loans, (y)
any outstanding Eurocurrency Loans in Dollars under the Facility shall be
converted, on the last day of the then-current Interest Period, to ABR Loans and
(z) any outstanding Eurocurrency Loans in an Optional Currency shall be prepaid
on the last day of the then-current Interest Period. Until such notice has been
withdrawn by the Administrative Agent, no further Eurocurrency Loans under the
Facility shall be made or continued as such, nor shall such Borrower have the
right to convert Loans under the Facility to Eurocurrency Loans.

     2.15   Pro Rata Treatment and Payments. (a) Each borrowing by a Borrower
            -------------------------------
from the Lenders hereunder, each payment by a Borrower on account of any
facility fee and any reduction of the Revolving Commitments of the Lenders shall
be made pro rata according to the respective Revolving Percentages of the
relevant Revolving Lenders.

     (b) Each payment (including each prepayment) by a Borrower on account of
principal of and interest on the Revolving Loans shall be made pro rata
                                                               --- ----
according to the respective outstanding principal amounts of the Revolving Loans
then held by the Revolving Lenders.

     (c) All payments (including prepayments) to be made by a Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
New York City time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Funding Office, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received. If any payment
hereunder (other than payments on the Eurocurrency Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurocurrency Loan becomes
due and payable on a day other than a Business Day, the maturity thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of

<PAGE>
                                                                              23

any payment of principal pursuant to the preceding two sentences, interest
thereon shall be payable at the then applicable rate during such extension.

     (d) Unless the Administrative Agent shall have been notified in writing by
any Lender prior to a borrowing that such Lender will not make the amount that
would constitute its share of such borrowing available to the Administrative
Agent, the Administrative Agent may assume that such Lender is making such
amount available to the Administrative Agent, and the Administrative Agent may,
in reliance upon such assumption, make available to a Borrower a corresponding
amount. If such amount is not made available to the Administrative Agent by the
required time on the Borrowing Date therefor, such Lender shall pay to the
Administrative Agent, on demand, such amount with interest thereon, at a rate
equal to the greater of (i) the Federal Funds Rate and (ii) a rate determined by
the Administrative Agent in accordance with banking industry rules on interbank
compensation, for the period until such Lender makes such amount immediately
available to the Administrative Agent. A certificate of the Administrative Agent
submitted to any Lender with respect to any amounts owing under this paragraph
shall be conclusive in the absence of manifest error. If such Lender's share of
such borrowing is not made available to the Administrative Agent by such Lender
within three Business Days after such Borrowing Date, the Administrative Agent
shall also be entitled to recover such amount with interest thereon at the rate
per annum applicable to ABR Loans under the Facility, on demand, from a
Borrower.

     (e) Unless the Administrative Agent shall have been notified in writing by
a Borrower prior to the date of any payment due to be made by such Borrower
hereunder that such Borrower will not make such payment to the Administrative
Agent, the Administrative Agent may assume that such Borrower is making such
payment, and the Administrative Agent may, but shall not be required to, in
reliance upon such assumption, make available to the Lenders their respective
pro rata shares of a corresponding amount. If such payment is not made to the
--- ----
Administrative Agent by such Borrower within three Business Days after such due
date, the Administrative Agent shall be entitled to recover, on demand, from
each Lender to which any amount which was made available pursuant to the
preceding sentence, such amount with interest thereon at the rate per annum
equal to the daily average Federal Funds Rate. Nothing herein shall be deemed to
limit the rights of the Administrative Agent or any Lender against the
Borrowers.

     2.16   Requirements of Law. (a) If the adoption of or any change in any
            -------------------
Requirement of Law or in the interpretation or application thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority made subsequent to
the date hereof:

          (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Letter of Credit, any Application or any
     Eurocurrency Loan made by it, or change the basis of taxation of payments
     to such Lender in respect thereof (except for Non-Excluded Taxes covered by
     Section 2.17 and changes in the rate of tax on the overall net income of
     such Lender);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender that is not otherwise included in the determination
     of the Eurocurrency Rate; or

          (iii) shall impose on such Lender any other condition;

<PAGE>
                                                                              24

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount that such Lender reasonably deems to be material, of making,
converting into, continuing or maintaining Eurocurrency Loans or issuing or
participating in Letters of Credit, or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the relevant Borrower shall promptly
pay such Lender, upon its demand, any additional amounts necessary to compensate
such Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this paragraph, it
shall promptly notify such Borrower (with a copy to the Administrative Agent) of
the event by reason of which it has become so entitled.

     (b) If any Lender shall have reasonably determined that the adoption of or
any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the relevant Borrower (with a copy to the
Administrative Agent) of a written request therefor, such Borrower shall pay to
such Lender such additional amount or amounts as will compensate such Lender or
such corporation for such reduction.

     (c) A certificate as to any additional amounts payable pursuant to this
Section submitted by any Lender to a Borrower (with a copy to the Administrative
Agent) shall be conclusive in the absence of manifest error. Notwithstanding
anything to the contrary in this Section, a Borrower shall not be required to
compensate a Lender pursuant to this Section for any amounts incurred more than
nine months prior to the date that such Lender notifies such Borrower of such
Lender's intention to claim compensation therefor; provided that, if the
                                                   --------
circumstances giving rise to such claim have a retroactive effect, then such
nine-month period shall be extended to include the period of such retroactive
effect. The obligations of such Borrower pursuant to this Section shall survive
the termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder.

     2.17   Taxes. (a) All payments made by a Borrower under this Agreement
            -----
shall be made free and clear of, and without deduction or withholding for or on
account of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority, excluding
net income taxes and franchise taxes (imposed in lieu of net income taxes)
imposed on the Administrative Agent or any Lender as a result of a present or
former connection between the Administrative Agent or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision or taxing authority thereof or therein (other than any such
connection arising solely from the Administrative Agent or such Lender having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or any other Loan Document). If any such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions or withholdings
("Non-Excluded Taxes") or Other Taxes are required to be withheld from any
  ------------------
amounts payable to the Administrative Agent or any Lender hereunder, the amounts
so payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes and Other Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement, provided, however, that a Borrower shall not be required to increase
           --------  -------
any such amounts payable to any Lender with respect to any Non-Excluded Taxes
(i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are
Non-Excluded Taxes imposed on amounts payable to such Lender as of the Closing
Date or, if

<PAGE>
                                                                              25

applicable, at such other time as such Lender becomes a party to this Agreement,
except to the extent that such Lender's assignor (if any) was entitled, at the
time of assignment, to receive additional amounts from such Borrower with
respect to such Non-Excluded Taxes pursuant to this paragraph.

     (b) In addition, Borrowers shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

     (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by a
Borrower, as promptly as possible thereafter such Borrower shall send to the
Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by such Borrower showing payment thereof. If such Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, such Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

     (d) Each Lender (or Transferee) that is not a "U.S. Person" as defined in
Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver to each
                                    ---------------
Borrower and the Administrative Agent (or, in the case of a Participant, to the
Lender from which the related participation shall have been purchased) two
copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or,
in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest", a statement substantially in the form of
Exhibit F and a Form W-8BEN, or any subsequent versions thereof or successors
thereto, properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by any Borrower under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify each Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrowers (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

     (e) A Lender that is entitled to an exemption from or reduction of non-U.S.
withholding tax under the law of the jurisdiction in which Solutions is located,
or any treaty to which such jurisdiction is a party, with respect to payments
under this Agreement shall deliver to Solutions (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law or
reasonably requested by Solutions, such properly completed and executed
documentation prescribed by applicable law as will permit such payments to be
made without withholding or at a reduced rate, provided that such Lender is
                                               --------
legally entitled to complete, execute and deliver such documentation and in such
Lender's judgment such completion, execution or submission would not materially
prejudice the legal position of such Lender.

     (f) If the Administrative Agent or any Lender determines, in its sole
discretion, that it has received a refund of any Non-Excluded Taxes or Other
Taxes as to which it has been indemnified by a Borrower or with respect to which
such Borrower has paid additional amounts pursuant to this Section 2.17, it
shall pay over such refund to such Borrower (but only to the extent of indemnity
payments made, or additional amounts paid, by such Borrower under this Section
2.17 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such
refund), net of all out-of-pocket expenses of the Administrative Agent or such
Lender and without interest (other than any interest paid by the relevant
Governmental

<PAGE>
                                                                              26

Authority with respect to such refund); provided, that such Borrower, upon the
request of the Administrative Agent or such Lender, agrees to repay the amount
paid over to such Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent or
such Lender in the event the Administrative Agent or such Lender is required to
repay such refund to such Governmental Authority. This paragraph shall not be
construed to require the Administrative Agent or any Lender to make available
its tax returns (or any other information relating to its taxes which it deems
confidential) to the Borrowers or any other Person.

     (g) The agreements in this Section shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

     2.18   Indemnity. Aeroflex agrees to indemnify each Lender for, and to hold
            ---------
each Lender harmless from, any loss or expense (in each case as reasonably
determined by such Lender) that such Lender may sustain or incur as a
consequence of (a) default by a Borrower in making a borrowing of, conversion
into or continuation of Eurocurrency Loans after such Borrower has given a
notice requesting the same in accordance with the provisions of this Agreement,
(b) default by a Borrower in making any prepayment of or conversion from
Eurocurrency Loans after such Borrower has given a notice thereof in accordance
with the provisions of this Agreement or (c) the making of a prepayment of
Eurocurrency Loans on a day that is not the last day of an Interest Period with
respect thereto (including as a result of an Event of Default). Without limiting
the generality of the foregoing, such indemnification shall include the costs
and expenses of each Lender that are attributable to the premature unwinding of
any hedging agreement entered into by such Lender in respect of the foreign
currency exposure attributable to such actual or proposed Eurocurrency Loan.
Such indemnification may include an amount equal to the excess, if any, of (i)
the amount of interest that would have accrued on the amount so prepaid, or not
so borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) that
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurocurrency
market. A certificate as to any amounts payable pursuant to this Section
submitted to Aeroflex by any Lender shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

     2.19   Change of Lending Office. Each Lender agrees that, upon the
            ------------------------
occurrence of any event giving rise to the operation of Section 2.16 or 2.17(a)
with respect to such Lender, it will, if requested by Aeroflex, use reasonable
efforts (subject to overall policy considerations of such Lender) to designate
another lending office for any Loans affected by such event with the object of
avoiding the consequences of such event; provided, that such designation is made
                                         --------
on terms that, in the sole judgment of such Lender, cause such Lender and its
lending office(s) to suffer no economic, legal or regulatory disadvantage, and
provided, further, that nothing in this Section shall affect or postpone any of
--------  -------
the obligations of the Borrowers or the rights of any Lender pursuant to Section
2.16 or 2.17(a).

     2.20   Replacement of Lenders. Aeroflex shall be permitted to replace any
            ----------------------
Lender that (a) requests reimbursement for amounts owing pursuant to Section
2.16 or 2.17(a) or (b) defaults in its obligation to make Loans hereunder, with
a replacement financial institution; provided that (i) such replacement does not
                                     --------
conflict with any Requirement of Law, (ii) no Event of Default shall have
occurred and be continuing at the time of such replacement, (iii) prior to any
such replacement, such Lender shall have taken no action under Section 2.19 so
as to eliminate the continued need for payment of amounts owing pursuant to
Section 2.16 or 2.17(a), (iv) the replacement financial institution shall
purchase, at par,

<PAGE>
                                                                              27

all Loans and other amounts owing to such replaced Lender on or prior to the
date of replacement, (v) the relevant Borrower shall be liable to such replaced
Lender under Section 2.18 if any Eurocurrency Loan owing to such replaced Lender
shall be purchased other than on the last day of the Interest Period relating
thereto, (vi) the replacement financial institution shall be reasonably
satisfactory to the Administrative Agent, (vii) the replaced Lender shall be
obligated to make such replacement in accordance with the provisions of Section
10.6 (provided that such Borrower shall be obligated to pay the registration and
processing fee referred to therein), (viii) until such time as such replacement
shall be consummated, such Borrower shall pay all additional amounts (if any)
required pursuant to Section 2.16 or 2.17(a), as the case may be, and (ix) any
such replacement shall not be deemed to be a waiver of any rights that the
Borrowers, the Administrative Agent or any other Lender shall have against the
replaced Lender.

                          SECTION 3. LETTERS OF CREDIT

     3.1   L/C Commitment. (a) Subject to the terms and conditions hereof, the
           --------------
Issuing Lender, in reliance on the agreements of the other Revolving Lenders set
forth in Section 3.4(a), agrees to issue letters of credit ("Letters of Credit")
                                                             -----------------
for the account of any Borrower on any Business Day during the Revolving
Commitment Period in such form as may be approved from time to time by the
Issuing Lender; provided that the Issuing Lender shall have no obligation to
                --------
issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C
Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the
Available Revolving Commitments would be less than zero. Each Letter of Credit
shall (i) be denominated in Dollars or an Optional Currency and (ii) expire no
later than the earlier of (x) the second anniversary of its date of issuance and
(y) the date that is five Business Days prior to the Revolving Termination Date,
provided that, as reasonably acceptable to the Administrative Agent, any Letter
--------
of Credit with a one-year or longer term may provide for the renewal thereof for
additional one-year periods (which shall in no event extend beyond the date
referred to in clause (y) above). All Existing Letters of Credit shall be deemed
to have been issued pursuant hereto, and from and after the Closing Date shall
be subject to and governed by the terms and conditions hereof.

     (b) The Issuing Lender shall not at any time be obligated to issue any
Letter of Credit if such issuance would conflict with, or cause the Issuing
Lender or any L/C Participant to exceed any limits imposed by, any applicable
Requirement of Law.

     3.2   Procedure for Issuance of Letter of Credit. A Borrower may from time
           ------------------------------------------
to time request that the Issuing Lender issue a Letter of Credit by delivering
to the Issuing Lender at its address for notices specified herein an Application
therefor, completed to the satisfaction of the Issuing Lender, and such other
certificates, documents and other papers and information as the Issuing Lender
may request. Upon receipt of any Application, the Issuing Lender will process
such Application and the certificates, documents and other papers and
information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall the Issuing Lender be required to issue any
Letter of Credit earlier than three Business Days after its receipt of the
Application therefor and all such other certificates, documents and other papers
and information relating thereto) by issuing the original of such Letter of
Credit to the beneficiary thereof or as otherwise may be agreed to by the
Issuing Lender and such Borrower. The Issuing Lender shall furnish a copy of
such Letter of Credit to such Borrower promptly following the issuance thereof.
The Issuing Lender shall promptly furnish to the Administrative Agent, which
shall in turn promptly furnish to the Lenders, notice of the issuance of each
Letter of Credit (including the amount thereof).

     3.3   Fees and Other Charges. (a) The relevant Borrower shall pay a fee on
           ----------------------
all outstanding Letters of Credit at a per annum rate equal to the Applicable
Margin then in effect with respect to Eurocurrency Loans under the Facility on
the face amount of each such Letter of Credit. Such

<PAGE>
                                                                              28

fee shall be shared ratably among the Revolving Lenders and shall be payable
quarterly in arrears on each Fee Payment Date after the issuance date. In
addition, such Borrower shall pay to the Issuing Lender for its own account a
fronting fee equal to 0.25% per annum on the undrawn and unexpired amount of
each Letter of Credit, payable quarterly in arrears on each Fee Payment Date
after the issuance date.

     (b) In addition to the foregoing fees, such Borrower shall pay or reimburse
the Issuing Lender for such normal and customary costs and expenses as are
incurred or charged by the Issuing Lender in issuing, negotiating, effecting
payment under, amending or otherwise administering any Letter of Credit.

     3.4   L/C Participations. (a) The Issuing Lender irrevocably agrees to
           ------------------
grant and hereby grants to each L/C Participant, and, to induce the Issuing
Lender to issue Letters of Credit, each L/C Participant irrevocably agrees to
accept and purchase and hereby accepts and purchases from the Issuing Lender, on
the terms and conditions set forth below, for such L/C Participant's own account
and risk an undivided interest equal to such L/C Participant's Revolving
Percentage in the Issuing Lender's obligations and rights under and in respect
of each Letter of Credit and the amount of each draft paid by the Issuing Lender
thereunder. Each L/C Participant agrees with the Issuing Lender that, if a draft
is paid under any Letter of Credit for which the Issuing Lender is not
reimbursed in full by the relevant Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at
the Issuing Lender's address for notices specified herein an amount equal to
such L/C Participant's Revolving Percentage of the amount of such draft, or any
part thereof, that is not so reimbursed. Each L/C Participant's obligation to
pay such amount shall be absolute and unconditional and shall not be affected by
any circumstance, including (i) any setoff, counterclaim, recoupment, defense or
other right that such L/C Participant may have against the Issuing Lender, such
Borrower or any other Person for any reason whatsoever, (ii) the occurrence or
continuance of a Default or an Event of Default or the failure to satisfy any of
the other conditions specified in Section 5, (iii) any adverse change in the
condition (financial or otherwise) of such Borrower, (iv) any breach of this
Agreement or any other Loan Document by such Borrower, any other Loan Party or
any other L/C Participant or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing

     (b) If any amount required to be paid by any L/C Participant to the Issuing
Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any
payment made by the Issuing Lender under any Letter of Credit is paid to the
Issuing Lender within three Business Days after the date such payment is due,
such L/C Participant shall pay to the Issuing Lender on demand an amount equal
to the product of (i) such amount, times (ii) the daily average Federal Funds
Rate (or, in the case of any such amount in an Optional Currency, the daily
average rate for the settlement of obligations between banks in such currency as
determined by the Administrative Agent) during the period from and including the
date such payment is required to the date on which such payment is immediately
available to the Issuing Lender, times (iii) a fraction the numerator of which
is the number of days that elapse during such period and the denominator of
which is 360. If any such amount required to be paid by any L/C Participant
pursuant to Section 3.4(a) is not made available to the Issuing Lender by such
L/C Participant within three Business Days after the date such payment is due,
the Issuing Lender shall be entitled to recover from such L/C Participant, on
demand, such amount with interest thereon calculated from such due date at the
rate per annum applicable to ABR Loans under the Facility (or, in the case of
any such amount in an Optional Currency, the overnight Eurocurrency Rate for
such Optional Currency plus the Applicable Margin for Eurocurrency Loans). A
certificate of the Issuing Lender submitted to any L/C Participant with respect
to any amounts owing under this Section shall be conclusive in the absence of
manifest error.

     (c) Whenever, at any time after the Issuing Lender has made payment under
any Letter of Credit and has received from any L/C Participant its pro rata
share of such payment in accordance with Section 3.4(a), the Issuing Lender
receives any payment related to such Letter of Credit (whether directly

<PAGE>
                                                                              29

from the relevant Borrower or otherwise, including proceeds of collateral
applied thereto by the Issuing Lender), or any payment of interest on account
thereof, the Issuing Lender will distribute to such L/C Participant its pro rata
share thereof; provided, however, that in the event that any such payment
               --------  -------
received by the Issuing Lender shall be required to be returned by the Issuing
Lender, such L/C Participant shall return to the Issuing Lender the portion
thereof previously distributed by the Issuing Lender to it.

     3.5   Reimbursement Obligation of the Borrowers. If any draft is paid under
           -----------------------------------------
any Letter of Credit, the relevant Borrower shall reimburse the Issuing Lender
for the amount of (a) the draft so paid and (b) any taxes, fees, charges or
other costs or expenses incurred by the Issuing Lender in connection with such
payment, not later than 12:00 Noon, New York City time, on (i) the Business Day
that such Borrower receives notice of such draft, if such notice is received on
such day prior to 10:00 A.M., New York City time, or (ii) if clause (i) above
does not apply, the Business Day immediately following the day that such
Borrower receives such notice. Each such payment shall be made to the Issuing
Lender at its address for notices referred to herein in Dollars or in the
relevant Optional Currency and in immediately available funds. Interest shall be
payable on any such amounts from the date on which the relevant draft is paid
until payment in full at the rate set forth in (x) until the Business Day next
succeeding the date of the relevant notice, Section 2.12(b) and (y) thereafter,
Section 2.12(c).

     3.6   Obligations Absolute. The relevant Borrower's obligations under this
           --------------------
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that such
Borrower may have or have had against the Issuing Lender, any beneficiary of a
Letter of Credit or any other Person. The Borrowers also agree with the Issuing
Lender that the Issuing Lender shall not be responsible for, and such Borrower's
Reimbursement Obligations under Section 3.5 shall not be affected by, among
other things, the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, or any dispute between or among such Borrower and any
beneficiary of any Letter of Credit or any other party to which such Letter of
Credit may be transferred or any claims whatsoever of such Borrower against any
beneficiary of such Letter of Credit or any such transferee. The Issuing Lender
shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the Issuing Lender. The Borrowers agree that any action taken or omitted by the
Issuing Lender under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct, shall be binding on such Borrower and shall not result in any
liability of the Issuing Lender to such Borrower.

     3.7   Letter of Credit Payments. If any draft shall be presented for
           -------------------------
payment under any Letter of Credit, the Issuing Lender shall promptly notify the
relevant Borrower of the date and amount thereof. The responsibility of the
Issuing Lender to such Borrower in connection with any draft presented for
payment under any Letter of Credit shall, in addition to any payment obligation
expressly provided for in such Letter of Credit, be limited to determining that
the documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are substantially in conformity with such
Letter of Credit.

     3.8   Applications. To the extent that any provision of any Application
           ------------
related to any Letter of Credit is inconsistent with the provisions of this
Section 3, the provisions of this Section 3 shall apply.

                                                                              30

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

     To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit, Aeroflex hereby represents and warrants to the Administrative Agent and
each Lender that:

     4.1   Financial Condition. The audited consolidated balance sheets of
           -------------------
Aeroflex as at June 30, 2004 and June 30, 2005, and the related consolidated
statements of operations and of cash flows for each of the years in the two year
period ended June 30, 2005, reported on by and accompanied by an unqualified
report from KPMG LLP, present fairly in all material respects the consolidated
financial condition of Aeroflex as at such dates, and the consolidated results
of its operations and its consolidated cash flows for the respective fiscal
years then ended. The unaudited consolidated balance sheet of Aeroflex as at
December 31, 2005, and the related unaudited consolidated statements of income
for the six-month and three-month periods then ended and cash flows for the
six-month period then ended, present fairly in all material respects the
consolidated financial condition of Aeroflex as at such date, and the
consolidated results of its operations and its consolidated cash flows for such
periods (subject to normal recurring year-end adjustments). All such financial
statements, including the related schedules and notes thereto, have been
prepared in accordance with GAAP applied consistently throughout the periods
involved (except as disclosed therein). As of the Closing Date, except as
incurred in the ordinary course of business or as are not material, no Group
Member has any material Guarantee Obligations, contingent liabilities and
liabilities for taxes, or any long-term leases or unusual forward or long-term
commitments, including any interest rate or foreign currency swap or exchange
transaction or other obligation in respect of derivatives, that are not
reflected or disclosed in the financial statements referred to in this
paragraph. During the period from June 30, 2005 to and including the date hereof
there has been no Disposition by any Group Member of any material part of its
business or property.

     4.2   No Change. Since June 30, 2005, there has been no development or
           ---------
event that has had or could reasonably be expected to have a Material Adverse
Effect.

     4.3   Existence; Compliance with Law. Each Group Member (other than each
           ------------------------------
Immaterial Subsidiary) (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (b) has the
power and authority, and the legal right, to own and operate its property, to
lease the property it operates as lessee and to conduct the business in which it
is currently engaged, (c) is duly qualified as a foreign corporation or other
organization and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification and (d) except as set forth on Schedule 4.3, is in
compliance with all Requirements of Law except, as to clauses (c) and (d), to
the extent that the failure to comply therewith could not, in the aggregate,
reasonably be expected to have a material adverse effect on the business,
property, operations, condition (financial or otherwise) or prospects of
Aeroflex and its Subsidiaries taken as a whole or, as to clause (d) to the
extent the failure to comply therewith could not, in the aggregate, reasonably
be expected to have a material adverse effect on the validity or enforceability
of this Agreement or any of the other Loan Documents or the rights or remedies
of the Administrative Agent or the Lenders hereunder or thereunder.

     4.4   Power; Authorization; Enforceable Obligations. Each Loan Party has

the power and authority, and the legal right, to make, deliver and perform the
Loan Documents to which it is a party and, in the case of the Borrowers, to
obtain extensions of credit hereunder. Each Loan Party has taken all necessary
organizational action to authorize the execution, delivery and performance of
the Loan Documents to which it is a party and, in the case of the Borrowers, to
authorize the extensions of credit on the terms and conditions of this
Agreement. No consent or authorization of, filing with, notice to or other act

extensions of credit hereunder or with the execution, delivery, performance,
validity or enforceability of this Agreement or any of the Loan Documents,
except consents, authorizations, filings and notices described in Schedule 4.4,
which consents, authorizations, filings and notices have been obtained or made
and are in full force and effect. Each Loan Document has been duly executed and
delivered on behalf of each Loan Party party thereto. This Agreement
constitutes, and each other Loan Document upon execution will constitute, a
legal, valid and binding obligation of each Loan Party party thereto,
enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

     4.5   No Legal Bar. The execution, delivery and performance of this
           ------------
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any
Requirement of Law or any Contractual Obligation of any Group Member and will
not result in, or require, the creation or imposition of any Lien on any of
their respective properties or revenues pursuant to any Requirement of Law or
any such Contractual Obligation. No Requirement of Law or Contractual Obligation
applicable to the Borrowers or any of their Subsidiaries could reasonably be
expected to have a material adverse effect on (x) the business, property,
operations, condition (financial or otherwise) or prospects of Aeroflex and its
Subsidiaries taken as a whole or (y) the validity or enforceability of this
Agreement or any of the other Loan Documents or the rights or remedies of the
Administrative Agent or the Lenders hereunder or thereunder.

     4.6   Litigation. Except as disclosed on Schedule 4.6, no litigation,
           ----------
investigation or proceeding of or before any arbitrator or Governmental
Authority is pending or, to the knowledge of Aeroflex, threatened by or against
any Group Member or against any of their respective properties or revenues (a)
with respect to any of the Loan Documents or any of the transactions
contemplated hereby or thereby, or (b) that could reasonably be expected to have
a Material Adverse Effect.

     4.7   No Default. No Group Member is in default under or with respect to
           ----------
any of its Contractual Obligations in any respect that could reasonably be
expected to have a Material Adverse Effect.

     4.8   Ownership of Property; Liens. Except as disclosed on Schedule 4.8,
           ----------------------------
each Group Member has title in fee simple to, or a valid leasehold interest in,
all its real property, and good title to, or a valid leasehold interest in, all
its other property, and none of such property is subject to any Lien except as
permitted by Section 7.3.

     4.9   Intellectual Property. To the knowledge of Aeroflex, each Group
           ---------------------
Member owns, or is licensed to use, all Intellectual Property material and
necessary for the conduct of its business as currently conducted. No material
claim has been asserted and is pending by any Person challenging or questioning
the use of any Intellectual Property or the validity or effectiveness of any
Intellectual Property. Except as set forth on Schedule 4.9, to the knowledge of
Aeroflex, the use of Intellectual Property by each Group Member does not
infringe on the rights of any Person in any material respect.

     4.10   Taxes. Each Group Member has filed or caused to be filed all
            -----
Federal, state and other material tax returns that are required to be filed and
has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other taxes, fees or
other charges imposed on it or any of its property by any Governmental Authority
(other than any the amount or validity of which are currently being contested in
good faith by appropriate proceedings and with respect to which reserves in
conformity with GAAP have been provided on the books of the relevant

<PAGE>
                                                                              32

Group Member); no tax Lien has been filed, and, to the knowledge of Aeroflex, no
claim is being asserted, with respect to any such tax, fee or other charge.

     4.11   Federal Regulations. No part of the proceeds of any Loans, and no
            -------------------
other extensions of credit hereunder, will be used (a) for "buying" or
"carrying" any "margin stock" within the respective meanings of each of the
quoted terms under Regulation U as now and from time to time hereafter in effect
for any purpose that violates the provisions of the Regulations of the Board or
(b) for any purpose that violates the provisions of the Regulations of the
Board.

     4.12   Labor Matters. Except as, in the aggregate, could not reasonably be
            -------------
expected to have a Material Adverse Effect: (a) there are no strikes or other
labor disputes against any Group Member pending or, to the knowledge of
Aeroflex, threatened; (b) hours worked by and payment made to employees of each
Group Member have not been in violation of the Fair Labor Standards Act or any
other applicable Requirement of Law dealing with such matters; and (c) all
payments due from any Group Member on account of employee health and welfare
insurance have been paid or accrued as a liability on the books of the relevant
Group Member.

     4.13   ERISA. Except as disclosed on Schedule 4.13, neither a Reportable
            -----
Event nor an "accumulated funding deficiency" (within the meaning of Section 412
of the Code or Section 302 of ERISA) has occurred during the five-year period
prior to the date on which this representation is made or deemed made with
respect to any Plan, and each Plan has complied in all material respects with
the applicable provisions of ERISA and the Code; provided, however, that the
provisions of this sentence shall be to the best of Aeroflex' knowledge with
respect to any Multiemployer Plan administered by a Person other than any
Borrower or ERISA Affiliate. No termination of a Single Employer Plan has
occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such
five-year period. The present value of all accrued benefits under each Single
Employer Plan (based on those assumptions used to fund such Plans) did not, as
of the last annual valuation date prior to the date on which this representation
is made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by a material amount. Except to the extent that the same
has not had or could not reasonably be expected to have a Material Adverse
Effect, neither Aeroflex nor any Commonly Controlled Entity has had a complete
or partial withdrawal from any Multiemployer Plan that has resulted or could
reasonably be expected to result in a liability under ERISA, and neither
Aeroflex nor any Commonly Controlled Entity would become subject to any
liability under ERISA if Aeroflex or any such Commonly Controlled Entity were to
withdraw completely from all Multiemployer Plans as of the valuation date most
closely preceding the date on which this representation is made or deemed made.
No such Multiemployer Plan is in Reorganization or Insolvent.

     4.14   Investment Company Act; Other Regulations. No Loan Party is an
            -----------------------------------------
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. No Loan
Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) that limits its ability to incur Indebtedness.

     4.15   Subsidiaries. Except as disclosed to the Administrative Agent by
            ------------
Aeroflex in writing from time to time after the Closing Date, (a) Schedule 4.15
sets forth the name and jurisdiction of incorporation of each Subsidiary and, as
to each such Subsidiary, the percentage of each class of Capital Stock owned by
any Loan Party and (b) there are no outstanding subscriptions, options,
warrants, calls, rights or other agreements or commitments (other than stock
options granted to employees, consultants or directors and directors' qualifying
shares) of any nature relating to any Capital Stock of the Borrowers or any
Subsidiary, except as created by the Loan Documents.

     4.16   Use of Proceeds. The proceeds of the Loans shall be used to finance
            ---------------
acquisitions, to finance the working capital needs and general corporate
purposes of the Borrowers and their Subsidiaries (including repatriation
associated with The American Jobs Creation Act), and to pay related fees and
expenses.

     4.17   Environmental Matters. Except as disclosed on Schedule 4.17 or as
            ---------------------
otherwise, in the aggregate, could not reasonably be expected to have a Material
Adverse Effect:

     (a) the facilities and properties owned, leased or operated by any Group
Member (the "Properties") do not contain any Materials of Environmental Concern
in amounts or concentrations or under circumstances that constitute a violation
of, or could reasonably be expected to give rise to liability under, any
Environmental Law;

     (b) no Group Member has received or, to the knowledge of Aeroflex, will
receive any notice of violation, alleged violation, non-compliance, liability or
potential liability regarding environmental matters or compliance with
Environmental Laws with regard to any of the Properties or the business operated
by any Group Member (the "Business"), nor does Aeroflex have knowledge of any
circumstances, conditions or events that could reasonably be expected to result
in any such notice being received or threatened;

     (c) Materials of Environmental Concern have not been transported or
disposed of by or on behalf of any Group Member from the Properties in violation
of, or in a manner or to a location that could reasonably be expected to give
rise to liability under, any Environmental Law, nor have any Materials of
Environmental Concern been generated, treated, stored or disposed of by or on
behalf of any Group Member at, on or under any of the Properties in violation
of, or in a manner that could reasonably be expected to give rise to liability
under, any applicable Environmental Law;

     (d) no judicial proceeding or governmental or administrative action is
pending or, to the knowledge of Aeroflex, threatened, under any Environmental
Law to which any Group Member is or will be named as a party with respect to the
Properties or the Business, nor are there any consent decrees or other decrees,
consent orders, administrative orders or other orders, or other administrative
or judicial requirements outstanding under any Environmental Law with respect to
the Properties or the Business;

     (e) there has been no release or threat of release of Materials of
Environmental Concern at or from the Properties, or arising from or related to
the operations of any Group Member in connection with the Properties or
otherwise in connection with the Business, in violation of or in amounts or in a
manner that could reasonably be expected to give rise to liability under
Environmental Laws;

     (f) the Properties and all operations at the Properties are in compliance,
and have, to the knowledge of Aeroflex, in the last five years been in
compliance, with all applicable Environmental Laws, and there is no
contamination at, under or about the Properties in violation of or in amounts
that could reasonably be expected to give rise to liability under any
Environmental Law with respect to the Properties or the Business;

     (g) no Group Member has assumed any liability of any other Person under
Environmental Laws; and

     (h) the matters set forth on Schedule 4.17, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

     4.18   Accuracy of Information, etc. No statement or information contained
            ----------------------------
in this Agreement, any other Loan Document, the Confidential Information
Memorandum or any other document, certificate or statement furnished by or on
behalf of any Loan Party to the Administrative Agent or the Lenders, or any of
them, for use in connection with the transactions contemplated by this Agreement

Confidential Information Memorandum, as of the date of this Agreement), any
untrue statement of a material fact or omitted to state a material fact
necessary to make the statements contained herein or therein not misleading.

     terminate for purposes of Title IV of ERISA, (v) any Group Member or any
     Commonly Controlled Entity shall, or in the reasonable opinion of the
     Required Lenders is likely to, incur any liability in connection with a
     withdrawal from, or the Insolvency or Reorganization of, a Multiemployer
     Plan or (vi) any other event or condition shall occur or exist with respect
     to a Plan; and in each case in clauses (i) through (vi) above, such event
     or condition, together with all other such events or conditions, if any,
     could, in the judgment of the Required Lenders, reasonably be expected to
     have a Material Adverse Effect; or

          (h) one or more judgments or decrees shall be entered against any
     Group Member involving in the aggregate a liability (not paid or fully
     covered by insurance as to which the relevant insurance company has
     acknowledged coverage) of $5,000,000 or more, and all such judgments or
     decrees shall not have been vacated, paid or discharged, stayed or bonded
     pending appeal within 30 days from the entry thereof; or

          (i) the guarantee contained in the Guarantee Agreement shall cease,
     for any reason, to be in full force and effect or any Loan Party or any
     Affiliate of any Loan Party shall so assert; or

          (j) a Change of Control shall occur;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to such Borrower,
automatically the Revolving Commitments shall immediately terminate and the
Loans (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required

<PAGE>
                                                                              45

thereunder) shall immediately become due and payable, and (B) if such event is
any other Event of Default, either or both of the following actions may be
taken: (i) with the consent of the Required Lenders, the Administrative Agent
may, or upon the request of the Required Lenders, the Administrative Agent
shall, by notice to such Borrower declare the Revolving Commitments to be
terminated forthwith, whereupon the Revolving Commitments shall immediately
terminate; and (ii) with the consent of the Required Lenders, the Administrative
Agent may, or upon the request of the Required Lenders, the Administrative Agent
shall, by notice to such Borrower, declare the Loans (with accrued interest
thereon) and all other amounts owing under this Agreement and the other Loan
Documents (including all amounts of L/C Obligations, whether or not the
beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required thereunder) to be due and payable forthwith, whereupon the
same shall immediately become due and payable. With respect to all Letters of
Credit with respect to which presentment for honor shall not have occurred at
the time of an acceleration pursuant to this paragraph, such Borrower shall at
such time deposit in a cash collateral account opened by the Administrative
Agent an amount equal to the aggregate then undrawn and unexpired amount of such
Letters of Credit. Amounts held in such cash collateral account shall be applied
by the Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of such Borrower hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
such Borrower hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to such Borrower (or such other Person as may be lawfully entitled thereto).
Except as expressly provided above in this Section, presentment, demand, protest
and all other notices of any kind are hereby expressly waived by the Borrowers.

                      SECTION 9. THE ADMINISTRATIVE AGENT

     9.1   Appointment. Each Lender hereby irrevocably designates and appoints
           -----------
the Administrative Agent as the agent of such Lender under this Agreement and
the other Loan Documents, and each such Lender irrevocably authorizes the
Administrative Agent, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Loan Documents and to exercise
such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

     9.2   Delegation of Duties. The Administrative Agent may execute any of its
           --------------------
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Administrative Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys in-fact
selected by it with reasonable care.

     9.3 Exculpatory Provisions. Neither the Administrative Agent nor any of its
         ----------------------
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except to the extent that any of the foregoing are found by
a final and nonappealable decision of a court of competent jurisdiction to have
resulted from its or such Person's own gross negligence or willful misconduct)
or (ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Loan Party or any officer

<PAGE>
                                                                              46

thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of any Loan Party a party thereto to perform its
obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Loan Party.

     9.4   Reliance by Administrative Agent. The Administrative Agent shall be
           --------------------------------
entitled to rely, and shall be fully protected in relying, upon any instrument,
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including counsel to the Borrowers), independent accountants and other experts
selected by the Administrative Agent. The Administrative Agent may deem and
treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with the Administrative Agent. The Administrative Agent shall be fully
justified in failing or refusing to take any action under this Agreement or any
other Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders (or, if so specified by this Agreement, all Lenders) as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense that may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the other Loan Documents in accordance with a request
of the Required Lenders (or, if so specified by this Agreement, all Lenders),
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all the Lenders and all future holders of the Loans.

     9.5   Notice of Default. The Administrative Agent shall not be deemed to
           -----------------
have knowledge or notice of the occurrence of any Default or Event of Default
unless the Administrative Agent has received notice from a Lender or a Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Lenders. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required Lenders (or, if so specified by this Agreement, all Lenders);
provided that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

     9.6   Non-Reliance on Administrative Agent and Other Lenders. Each Lender
           ------------------------------------------------------
expressly acknowledges that neither the Administrative Agent nor any of its
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates have made any representations or warranties to it and that no act by
the Administrative Agent hereafter taken, including any review of the affairs of
a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender. Each
Lender represents to the Administrative Agent that it has, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and their
affiliates and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not

<PAGE>
                                                                              47

taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of any Loan Party or any affiliate of
a Loan Party that may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

     9.7   Indemnification. The Lenders agree to indemnify the Administrative
           ---------------
Agent in its capacity as such (to the extent not reimbursed by Aeroflex and
without limiting the obligation of Aeroflex to do so), ratably according to
their respective Aggregate Exposure Percentages in effect on the date on which
indemnification is sought under this Section (or, if indemnification is sought
after the date upon which the Revolving Commitments shall have terminated and
the Loans shall have been paid in full, ratably in accordance with such
Aggregate Exposure Percentages immediately prior to such date), from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever that
may at any time (whether before or after the payment of the Loans) be imposed
on, incurred by or asserted against the Administrative Agent in any way relating
to or arising out of, the Revolving Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by the Administrative Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements that are found by a final and
nonappealable decision of a court of competent jurisdiction to have resulted
from the Administrative Agent's gross negligence or willful misconduct. The
agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

     9.8   Administrative Agent in Its Individual Capacity. The Administrative
           -----------------------------------------------
Agent and its affiliates may make loans to, accept deposits from and generally
engage in any kind of business with any Loan Party as though the Administrative
Agent were not an agent. With respect to its Loans made or renewed by it and
with respect to any Letter of Credit issued or participated in by it, the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not an agent, and the terms "Lender" and "Lenders" shall include the
Administrative Agent in its individual capacity.

     9.9   Successor Administrative Agent. The Administrative Agent may resign
           ------------------------------
as Administrative Agent upon 10 days' notice to the Lenders and Aeroflex. If the
Administrative Agent shall resign as Administrative Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent for the Lenders, which successor agent shall
(unless an Event of Default under Section 8(a) or Section 8(f) with respect to a
Borrower shall have occurred and be continuing) be subject to approval by
Aeroflex (which approval shall not be unreasonably withheld or delayed),
whereupon such successor agent shall succeed to the rights, powers and duties of
the Administrative Agent, and the term "Administrative Agent" shall mean such
successor agent effective upon such appointment and approval, and the former
Administrative Agent's rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans. If no successor agent has accepted appointment as
Administrative Agent by the date that is 10 days following a retiring
Administrative Agent's notice of resignation, the retiring Administrative
Agent's resignation shall nevertheless thereupon become

<PAGE>
                                                                              48

effective, and the Lenders shall assume and perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above. After any retiring
Administrative Agent's resignation as Administrative Agent, the provisions of
this Section 9 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Administrative Agent under this Agreement and the
other Loan Documents.

                           SECTION 10.   MISCELLANEOUS

     10.1   Amendments and Waivers. Neither this Agreement, any other Loan
            ----------------------
Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1. The
Required Lenders and each Loan Party party to the relevant Loan Document may,
or, with the written consent of the Required Lenders, the Administrative Agent
and each Loan Party party to the relevant Loan Document may, from time to time,
(a) enter into written amendments, supplements or modifications hereto and to
the other Loan Documents for the purpose of adding any provisions to this
Agreement or the other Loan Documents or changing in any manner the rights of
the Lenders or of the Loan Parties hereunder or thereunder or (b) waive, on such
terms and conditions as the Required Lenders or the Administrative Agent, as the
case may be, may specify in such instrument, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; provided, however, that no such waiver and no such amendment,
supplement or modification shall (i) forgive the principal amount or extend the
final scheduled date of maturity of any Loan, reduce the stated rate of any
interest or fee payable hereunder (except (x) in connection with the waiver of
applicability of any post-default increase in interest rates (which waiver shall
be effective with the consent of the Required Lenders) and (y) that any
amendment or modification of defined terms used in the financial covenants in
this Agreement shall not constitute a reduction in the rate of interest or fees
for purposes of this clause (i)) or extend the scheduled date of any payment
thereof, or increase the amount or extend the expiration date of any Lender's
Revolving Commitment, in each case without the written consent of each Lender
directly affected thereby; (ii) eliminate or reduce the voting rights of any
Lender under this Section 10.1 without the written consent of such Lender; (iii)
reduce any percentage specified in the definition of Required Lenders, consent
to the assignment or transfer by a Borrower of any of its rights and obligations
under this Agreement and the other Loan Documents, or release any significant
Guarantor from its obligations under the Guarantee Agreement, in each case
without the written consent of all Lenders; (iv) reduce the percentage specified
in the definition of Required Lenders without the written consent of all
Lenders; (v) amend, modify or waive any provision of Section 9 without the
written consent of the Administrative Agent; (vi) amend, modify or waive any
provision of Section 2.3 or 2.4 without the written consent of the Swingline
Lender; or (vii) amend, modify or waive any provision of Section 3 without the
written consent of the Issuing Lender. Any such waiver and any such amendment,
supplement or modification shall apply equally to each of the Lenders and shall
be binding upon the Loan Parties, the Lenders, the Administrative Agent and all
future holders of the Loans. In the case of any waiver, the Loan Parties, the
Lenders and the Administrative Agent shall be restored to their former position
and rights hereunder and under the other Loan Documents, and any Default or
Event of Default waived shall be deemed to be cured and not continuing; but no
such waiver shall extend to any subsequent or other Default or Event of Default,
or impair any right consequent thereon.

     10.2   Notices. All notices, requests and demands to or upon the respective

(all the foregoing in this clause (d), collectively, the "Indemnified
                                                          -----------

Indemnitee with respect to Indemnified Liabilities to the extent such
Indemnified Liabilities are found by a final and nonappealable decision of a

willful misconduct of such Indemnitee. Without limiting the foregoing, and to
the extent permitted by applicable law, Aeroflex agrees not to assert and to
cause its Subsidiaries not to assert, and hereby waives and agrees to cause its
Subsidiaries to waive, all rights for contribution or any other rights of
recovery with respect to

all claims, demands, penalties, fines, liabilities, settlements, damages, costs
and expenses of whatever kind or nature, under or related to Environmental Laws,
that any of them might have by statute or otherwise against any Indemnitee. All
amounts due under this Section 10.5 shall be payable not later than 10 business

this Section 10.5 shall be submitted to Aeroflex as set forth in Section 10.2,
or to such other Person or address as may be hereafter designated by Aeroflex in
a written notice to the Administrative Agent. The agreements in this Section
10.5 shall survive repayment of the Loans and all other amounts payable
hereunder.

     10.6   Successors and Assigns; Participations and Assignments. (a) The
            ------------------------------------------------------
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns permitted hereby
(including any affiliate of the Issuing Lender that issues any Letter of
Credit), except that (i) a Borrower may not assign or otherwise transfer any of
its rights or obligations hereunder without the prior written consent of each
Lender (and any attempted assignment or transfer by any Borrower without such
consent shall be null and void) and (ii) no Lender may assign or otherwise
transfer its rights or obligations hereunder except in accordance with this
Section.

          (b)(i) Subject to the conditions set forth in paragraph (b)(ii) below,
     any Lender may assign to one or more assignees (each, an "Assignee") all or
                                                               --------
     a portion of its rights and obligations under this Agreement (including all
     or a portion of its Revolving Commitments and the Loans at the time owing
     to it) with the prior written consent of:

          (A) Aeroflex (such consent not to be unreasonably withheld), provided
                                                                       --------
     that no consent of Aeroflex shall be required for an assignment to a
     Lender, an affiliate of a Lender, an Approved Fund (as defined below) or,
     if an Event of Default under Section 8(a) or (f) has occurred and is
     continuing, any other Person; and

          (B) the Administrative Agent.

          (ii) Assignments shall be subject to the following additional
     conditions:

          (A) except in the case of an assignment to a Lender, an affiliate of a
     Lender or an Approved Fund or an assignment of the entire remaining amount
     of the assigning Lender's Revolving Commitments or Loans under the
     Facility, the amount of the Revolving Commitments or Loans of the assigning
     Lender subject to each such assignment (determined as of the date the
     Assignment and Assumption with respect to such assignment is delivered to
     the Administrative Agent) shall not be less than $5,000,000 unless each of
     Aeroflex and the Administrative Agent otherwise consent, provided that (1)
     no such consent of Aeroflex shall be required if an Event of Default under
     Section 8(a) or (f) has occurred and is continuing and (2) such amounts
     shall be aggregated in respect of each Lender and its affiliates or
     Approved Funds, if any;

          (B) the parties to each assignment shall execute and deliver to the
     Administrative Agent an Assignment and Assumption, together with a
     processing and recordation fee of $3,500; and

          (C) the Assignee, if it shall not be a Lender, shall deliver to the
     Administrative Agent an Administrative Questionnaire.

     For the purposes of this Section 10.6, "Approved Fund" means any Person
                                             -------------
(other than a natural person) that is engaged in making, purchasing, holding or
investing in bank loans and similar extensions of credit in the ordinary course
of its business and that is administered or managed by (a) a Lender, (b) an
affiliate of a Lender or (c) an entity or an affiliate of an entity that
administers or manages a Lender.

     (iii) Subject to acceptance and recording thereof pursuant to paragraph
(b)(iv) below, from and after the effective date specified in each Assignment
and Assumption the Assignee thereunder shall be a party hereto and, to the
extent of the interest assigned by such Assignment and Assumption, have the
rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.16, 2.17, 2.18 and 10.5). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this Section 10.6
shall be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (c) of
this Section.

     (iv) The Administrative Agent, acting for this purpose as an agent of the
Borrowers, shall maintain at one of its offices a copy of each Assignment and
Assumption delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Revolving Commitments of, and principal amount
of the Loans and L/C Obligations owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Borrowers, the Administrative Agent, the Issuing Lender and
the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary.

     (v) Upon its receipt of a duly completed Assignment and Assumption executed
by an assigning Lender and an Assignee, the Assignee's completed Administrative
Questionnaire (unless the Assignee shall already be a Lender hereunder), the
processing and recordation fee referred to in paragraph (b) of this Section and
any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Assumption
and record the information contained therein in the Register. No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.

     (c)(i) Any Lender may, without the consent of the Borrowers or the
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
    -----------
under this Agreement (including all or a portion of its Revolving Commitments
and the Loans owing to it); provided that (A) such Lender's obligations under
                            --------
this Agreement shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (C) the Borrowers, the Administrative Agent, the Issuing Lender and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement may provide that such Lender will not,
           --------
without the consent of the Participant, agree to any amendment, modification or
waiver that (1) requires the consent of each Lender directly affected thereby
pursuant to the proviso to the second sentence of Section 10.1 and (2) directly
affects such Participant. Subject to paragraph (c)(ii) of this Section, the
Borrowers agree that each Participant shall be entitled to the benefits of
Sections 2.16, 2.17 and 2.18 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section.
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 10.7(b) as though it were a Lender, provided such
Participant shall be subject to Section 10.7(a) as though it were a Lender.

<PAGE>
                                                                              53

     (ii) A Participant shall not be entitled to receive any greater payment
under Section 2.16 or 2.17 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with Aeroflex's prior
written consent. Any Participant that is a Non-U.S. Lender shall not be entitled
to the benefits of Section 2.17 unless such Participant complies with Section
2.17(d).

     (d) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a security
                        --------
interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or Assignee for such Lender as a party hereto.

     (e) The Borrowers, upon receipt of written notice from the relevant Lender,
agree to issue Notes to any Lender requiring Notes to facilitate transactions of
the type described in paragraph (d) above.

     (f) Notwithstanding the foregoing, any Conduit Lender may assign any or all
of the Loans it may have funded hereunder to its designating Lender without the
consent of the Borrowers or the Administrative Agent and without regard to the
limitations set forth in Section 10.6(b). Each of the Borrowers, each Lender and
the Administrative Agent hereby confirms that it will not institute against a
Conduit Lender or join any other Person in instituting against a Conduit Lender
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under any state bankruptcy or similar law, for one year and one day
after the payment in full of the latest maturing commercial paper note issued by
such Conduit Lender; provided, however, that each Lender designating any Conduit
                     --------
Lender hereby agrees to indemnify, save and hold harmless each other party
hereto for any loss, cost, damage or expense arising out of its inability to
institute such a proceeding against such Conduit Lender during such period of
forbearance.

     10.7   Adjustments; Set-off. (a) Except to the extent that this Agreement
            --------------------
expressly provides for payments to be allocated to a particular Lender or to the
Lenders under the Facility, if any Lender (a "Benefitted Lender") shall, at any
                                              -----------------
time after the Loans and other amounts payable hereunder shall immediately
become due and payable pursuant to Section 8, receive any payment of all or part
of the Obligations owing to it, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 8(f), or otherwise), in a
greater proportion than any such payment to or collateral received by any other
Lender, if any, in respect of the Obligations owing to such other Lender, such
Benefitted Lender shall purchase for cash from the other Lenders a participating
interest in such portion of the Obligations owing to each such other Lender, or
shall provide such other Lenders with the benefits of any such collateral, as
shall be necessary to cause such Benefitted Lender to share the excess payment
or benefits of such collateral ratably with each of the Lenders; provided,
                                                                 --------
however, that if all or any portion of such excess payment or benefits is
-------
thereafter recovered from such Benefitted Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.

     (b) In addition to any rights and remedies of the Lenders provided by law,
each Lender shall have the right, without prior notice to the Borrowers, any
such notice being expressly waived by the Borrowers to the extent permitted by
applicable law, upon any amount becoming due and payable by any Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise), to set
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or

<PAGE>
                                                                              54

owing by such Lender or any branch or agency thereof to or for the credit or the
account of any Borrower, as the case may be. Each Lender agrees promptly to
notify such Borrower and the Administrative Agent after any such setoff and
application made by such Lender, provided that the failure to give such notice
                                 --------
shall not affect the validity of such setoff and application.

     10.8   Counterparts. This Agreement may be executed by one or more of the
            ------------
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with Aeroflex and the Administrative Agent.

     10.9   Severability. Any provision of this Agreement that is prohibited or
            ------------
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     10.10  Integration. This Agreement and the other Loan Documents represent
            -----------
the entire agreement of the Borrowers, the Administrative Agent and the Lenders
with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to the subject matter hereof not expressly set
forth or referred to herein or in the other Loan Documents.

     10.11  GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
            -------------

     the State of New York, the courts of the United States for the Southern
     District of New York, and appellate courts from any thereof;

          (b) consents that any such action or proceeding may be brought in such
     courts and waives any objection that it may now or hereafter have to the
     venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c) agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     relevant Borrower, at the addresses set forth in Section 10.2 or at such
     other address of which the Administrative Agent shall have been notified
     pursuant thereto;
