respectively) with respect to the Plans, has engaged in any nonexempt
"prohibited transaction" (within the meaning of Section 406 of ERISA or Section
4975(c) of the Code, respectively) with respect to the participation of Company
or any of its Subsidiaries therein, which could subject any of the Plans or

Plan, or the Company, any Subsidiary of the Company or the Purchasers, or any
other party dealing with the Plans, to the penalties or excise tax imposed on
prohibited transactions by Section 502 of ERISA or Section 4975 of the Code

     7.1 INDEMNIFICATION. In addition to all other sums due hereunder or
provided for in this Agreement, the Company agrees to indemnify and hold
harmless each of the Purchasers and their respective Affiliates and each of
their respective officers, directors, agents, employees, subsidiaries, partners,
attorneys, accountants and controlling persons (each, an "INDEMNIFIED PARTY") to
the fullest extent permitted by law from and against any and all losses, claims,
damages, expenses (including, without limitation, reasonable fees, disbursements
and other charges of counsel incurred by an Indemnified Party in any action or
proceeding between the Company and such Indemnified Party (or Indemnified
Parties), or between an Indemnified Party (or Indemnified Parties) and any third
party or otherwise) or other liabilities, losses, or diminution in value
(collectively, "LIABILITIES") resulting from or arising out of any breach of any
representation or warranty, covenant or agreement of the Company in this
Agreement, the Registration Rights Agreement, the Stockholders' Agreement, the
Notes, the Warrants, or the other Transaction Documents, including without
limitation, the failure to make payment when due of amounts owing pursuant to
this Agreement, the Notes or the other Transaction Documents, on the due date
thereof (whether at the scheduled maturity, by acceleration

                                       36
<PAGE>

or otherwise) or any legal, administrative or other actions (including, without
limitation, actions brought by a Purchaser, the Company, any of its Subsidiaries
or any equity holders of the Company or any of its Subsidiaries or derivative
actions brought by any Person claiming through or in the Company's or any
Subsidiary's name), proceedings or investigations (whether formal or informal),
or written threats thereof, based upon, relating to or arising out of the
Transaction Documents, the transactions contemplated thereby, or any Indemnified
Party's role therein or in the transactions contemplated thereby; PROVIDED,
HOWEVER, that the Company shall not be liable under this Section 7.1 to an
Indemnified Party: (a) for any amount paid by the Indemnified Party in
settlement of claims by the Indemnified Party without the Company's consent
(which consent shall not be unreasonably withheld), (b) to the extent that it is
finally judicially determined that such Liabilities resulted primarily from the
willful misconduct or gross negligence of such Indemnified Party or (c) to the
extent that it is finally judicially determined that such Liabilities resulted
primarily from the breach by such Indemnified Party of any representation,
warranty, covenant or other agreement of such Indemnified Party contained in
this Agreement; PROVIDED, FURTHER, that if and to the extent that such
indemnification is unenforceable for any reason, the Company shall make the
maximum contribution to the payment and satisfaction of such Liabilities which
shall be permissible under applicable laws. In connection with the obligation of
the Company to indemnify for expenses as set forth above, the Company further
agrees, upon presentation of appropriate invoices containing reasonable detail,
to reimburse each Indemnified Party for all such expenses (including, without
limitation, fees, disbursements and other charges of counsel incurred by an
Indemnified Party in any action or proceeding between the Company, and such
Indemnified Party (or Indemnified Parties), or between an Indemnified Party (or
Indemnified Parties) and any third party or otherwise) as they are incurred by
such Indemnified Party; PROVIDED, HOWEVER, that if an Indemnified Party is
reimbursed hereunder for any expenses, such reimbursement of expenses shall be
refunded to the extent it is finally judicially determined that the Liabilities
in question resulted primarily from (i) the willful misconduct or gross
negligence of such Indemnified Party or (ii) the breach by such Indemnified
Party of any representation, warranty, covenant or other agreement of such
Indemnified Party contained in this Agreement or any other Transaction Document.

     7.2 PROCEDURE; NOTIFICATION. Each Indemnified Party under this Article 7
will, promptly after the receipt of notice of the commencement of any action,
investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from the Company under this Article 7,
notify the Company in writing of the commencement thereof. The omission of any
Indemnified Party so to notify the Company of any such action shall not relieve
the Company from any liability which it may have to such Indemnified Party
unless, and only to the extent that, such omission results in the Company's
forfeiture of substantive rights or defenses. In case any such action, claim or
other proceeding shall be brought against any Indemnified Party and it shall
notify the Company of the commencement thereof, the Company shall be entitled to
assume the defense thereof at its own expense, with counsel satisfactory to such
Indemnified Party in its reasonable judgment; PROVIDED, HOWEVER, that any
Indemnified Party may, at its own expense, retain separate counsel to
participate in such defense. Notwithstanding the foregoing, in any action, claim
or proceeding in which the Company and an Indemnified Party are, or are
reasonably likely to become, parties, such Indemnified Party shall have the
right to employ separate counsel at the Company's expense and to control its own
defense of such action, claim or proceeding if, in the reasonable opinion of
counsel to such Indemnified Party, a conflict or potential conflict exists
between the Company, on the one hand, and such Indemnified Party, on the other
hand, that would

                                       37
<PAGE>

make such separate representation advisable; PROVIDED, HOWEVER, that in no event
shall the Company be required to pay fees and expenses under this Article 7 for
more than one firm of attorneys in any jurisdiction in any one legal action or
group of related legal actions. The Company agrees that it will not, without the
prior written consent of the Purchasers, settle, compromise or consent to the
entry of any judgment in any pending or threatened claim, action or proceeding
relating to the matters contemplated hereby (if any Indemnified Party is a party
thereto or has been actually threatened to be made a party thereto) unless such
settlement, compromise or consent includes an unconditional release of the
Purchasers and each other Indemnified Party from all liability arising or that
may arise out of such claim, action or proceeding. The Company shall not be
liable for any settlement of any claim, action or proceeding effected against an
Indemnified Party without its written consent, which consent shall not be
unreasonably withheld. The rights accorded to Indemnified Parties hereunder
shall be in addition to any rights that any Indemnified Party may have at common
law, by separate agreement or otherwise.

     7.3 REGISTRATION RIGHTS AGREEMENT. Notwithstanding anything to the contrary
in this Article 7, the indemnification and contribution provisions of the
Registration Rights Agreement shall govern any claim made with respect to
registration statements filed pursuant thereto or sales made thereunder.

                                  ARTICLE VIII

                              AFFIRMATIVE COVENANTS

January 23, 2002

Integrated Defense Technologies, Inc.
110 Wynn Drive
Huntsville, Alabama 35807
Attention: Robert McKeon

           Re: CREDIT FACILITIES FOR INTEGRATED DEFENSE TECHNOLOGIES, INC.

Gentlemen:

DESCRIPTION OF REFINANCING

         You have advised us that Integrated Defense Technologies, Inc.
("COMPANY"), a portfolio company of Veritas Capital Partners, LLC ("VERITAS"),
has existing indebtedness in the outstanding principal amount of approximately
$180.0 million (the "EXISTING INDEBTEDNESS"). You have further advised us that
the Company intends to refinance or repay the Existing Indebtedness, and in
connection with the Refinancing, pay a mandatory redemption price under the
Company's Senior Subordinated Notes of approximately $2.6 million (the
"PREPAYMENT PENALTY") and related transaction costs in an amount not to exceed
$8.5 million (collectively, the "Refinancing"). You have advised us that in
connection with the Refinancing, you will require approximately $192.0 million,
consisting of (i) a senior secured credit facility of $135.0 million, of which
amount approximately $99.0 million will be borrowed on the date of closing (the
"CLOSING DATE"), and (ii) no less than $93.0 million in net proceeds from an
initial public offering ("IPO") of approximately 20% of the Company, which IPO
is anticipated to be consummated in February, 2002. As used in this letter,
"TRANSACTION" means consummation of the Refinancing, IPO and Credit Facility.

DESCRIPTION OF CREDIT FACILITY

         Canadian Imperial Bank of Commerce is pleased to confirm that it or one
or more of its agencies, branches or affiliates, including CIBC World Markets
Corp. (collectively, "CIBC") is willing to underwrite the $135.0 million Credit
Facility described below and in the Summary of Terms and Conditions attached as
ANNEX A hereto (the "TERM SHEET"), subject to the terms and conditions set forth
in this Letter and the Term Sheet

         The senior bank credit facilities to be provided to the Company will
consist of a $45.0 million five-year term loan A credit facility (the "TERM LOAN
A FACILITY"), a $50.0 million six-year term loan B credit facility (the "TERM
LOAN B FACILITY" and, together with the Term Loan A Facility, the "TERM LOANS"),
and an up to $40.0 million five-year revolving credit facility (the "REVOLVER";
and together with the Term Loans, the "CREDIT FACILITY"). Up to $25.0

                                       1
<PAGE>

million of the Revolver will be made available for the issuance of letters of
credit. The Company may increase one or more tranches under the Credit Facility,
at CIBC's and the Company's mutual discretion, in an aggregate amount of up to
$50.0 million, at any time prior to two years after the closing (the "GREENSHOE
OPTION") from willing lenders or eligible assignees, subject to the terms and
conditions contained in this Letter and the Term Sheet.

         The Company hereby agrees that CIBC will act as Lead Arranger and Book
Runner for the Credit Facility. CIBC will use commercially reasonable efforts to
arrange for a syndicate of other banks, financial institutions and other
"accredited investors" (as defined in SEC regulations; each such bank, financial
institution and accredited investor, including CIBC, being a "LENDER" and,
collectively, the "LENDERS") to participate in the Credit Facility. In addition,
CIBC reserves the right to arrange for other Lenders to provide a portion of its
share of the Credit Facility. CIBC will act as administrative agent for the
Lenders (in such capacity, the "ADMINISTRATIVE AGENT"). The Company hereby
agrees that no other agents, co-agents or arrangers will be appointed, no other
titles will be awarded and no compensation (other than as expressly set forth in
the Term Sheet and accompanying fee letter dated as of the date hereof (the "FEE
LETTER")) will be paid in connection with the Credit Facility unless CIBC shall
so agree. As used herein, the term "SENIOR LOAN DOCUMENTATION" shall mean the
definitive financing documents under which the Credit Facility is provided.

CONDITIONS PRECEDENT

         This commitment is based upon our investigation to date and is subject
to CIBC obtaining satisfactory results from the completion of our and our
counsel's confirmatory due diligence. CIBC confirms that it has substantially
completed its due diligence investigation of the business, assets, results of
operations, properties and condition (financial and other) of the Company and
its subsidiaries (collectively, the "LOAN PARTIES") and is substantially
satisfied with the results of its investigations. If our continuing review of
the Loan Parties discloses information relating to conditions or events not
previously disclosed to us or relating to new information or additional
developments concerning conditions or events previously disclosed to us which we
believe may have a material adverse effect on the business, operations,
properties, assets, liabilities, condition (financial or otherwise) or prospects
of the Loan Parties or the Transaction, we may, in our sole discretion, suggest
alternative financing amounts or structures that ensure adequate protection for
the Lenders or decline to participate in the proposed financing.

         CIBC's commitment hereunder and CIBC's agreement to perform the
services described herein are subject to the following: (i) repayment of all
principal, interest and other amounts due in connection with the Existing
Indebtedness, including, without limitation, the $2.6 million Prepayment
Penalty, and termination of all documents evidencing or securing the Existing
Indebtedness, (ii) since the date of the Company's last audited financial
statements, nothing shall have occurred which could reasonably be likely to have
a material adverse effect on the ability of any Loan Party to perform its
obligations, and to avoid default, under the Senior Loan Documentation or
consummate the Transaction, (iii) our not becoming aware after the date hereof
of any information or other matter affecting the Transaction or the Loan Parties
that is inconsistent in a material and adverse manner with any Information (as
defined below), including all Projections (as defined below) disclosed to us
prior to the date hereof, which

                                       2
<PAGE>

information or other matter we reasonably believe could be expected to have a
material adverse effect on the business, operations, condition (financial or
otherwise), assets or liabilities (including the Projections) of the Loan
Parties or the Transaction, (iv) our satisfaction that prior to and during the
syndication of the Credit Facility there shall be no competing offering,
placement or arrangement of any debt securities or bank financing by or on
behalf of the Company, (v) the consummation, prior to or concurrently with the
closing of the Credit Facility, of the IPO in form and substance satisfactory to

satisfaction of CIBC in all material respects with the material terms of all
material agreements relating to the Transaction, and (vii) the negotiation,

in each case prepared by CIBC's counsel and satisfactory to CIBC and the

provisions that CIBC reasonably may deem appropriate. CIBC's commitment shall
also be subject to CIBC's determination that there has been no suspension of
capital markets and that there has not occurred any material disruption or
material adverse change in (i) the business, operations, properties, assets,
liabilities, condition (financial or otherwise) or prospects of the Loan
Parties, or (ii) the financial or capital markets in which CIBC participate.
Those matters that are not covered by the provisions hereof, of the Fee Letter

SYNDICATION

         As we discussed, CIBC intends to arrange for the syndication of the
Credit Facility. CIBC in consultation with Veritas will manage all aspects of
the syndication, including decisions as to the selection of institutions to be
approached and when they will be approached, when their commitments will be
accepted, the allocations of the commitments among the Lenders and the amount
and distribution of fees among the Lenders. In that regard, the Company agrees
to actively assist (and to cause Veritas to actively assist) CIBC in the
syndication of the Credit Facility, which assistance will require, among other
things, that the Company and the other Loan Parties, provide all information
CIBC reasonably deems to be necessary to successfully complete the syndication.

         In addition, the Company agrees to promptly provide, and use its
reasonable best efforts to cause its consultants and advisors to promptly
provide, to CIBC all financial and other information in its or their possession
with respect to the Transaction and the Loan Parties, including but not limited
to information and projections prepared by any Loan Party or any of their
advisors. The Company also agrees, during regular business hours, to answer
questions, and to use its reasonable best efforts to cause its consultants and
advisors to answer questions, regarding the Credit Facility, to review and
assist in the preparation of the syndication memorandum relating to the Credit
Facility, to meet with prospective Lenders and to use commercially reasonable
efforts to ensure that CIBC's syndication efforts benefit from the lending
relationships of Veritas and the Loan Parties.

         CIBC shall have the right to fully syndicate the Credit Facility prior
to the Closing Date. CIBC shall be entitled at its reasonable discretion, after
consultation with the Company, to modify the structure, pricing (including
interest and fees) or terms of the Credit Facility to reflect market conditions
or if CIBC determines that such changes are advisable in order to ensure a
successful syndication.

                                       3

         The Company represents that, based on its review and analysis, (a) all
information, other than Projections (as defined below), which has been or is
hereafter made available to CIBC or the other Lenders by the Company or any
other Loan Party or any of their respective representatives in connection with
the Transaction (the "INFORMATION") has been reviewed and analyzed by the
Company and, as supplemented as contemplated by the next sentence, is (or will
be, in the case of Information made available after the date hereof) complete
and correct in all material respects when taken as a whole and does not (or will
not, as the case may be) contain any untrue statement of a material fact or omit
to state a material fact necessary to make the statements contained therein not
materially misleading in light of the circumstances under which such statements
were or are made, and (b) all financial projections concerning the Loan Parties
and the Transaction that have been or are hereafter made available to CIBC or
the other Lenders by the Company or the other Loan Parties or any of their
respective representatives in connection with the Transaction (the
"PROJECTIONS") have been (or will be, in the case of Projections made available
after the date hereof) prepared in good faith based upon reasonable assumptions.
The Company agrees to supplement the Information and the Projections from time
to time until the Closing Date so that the representation and warranty in the
preceding sentence is correct on the Closing Date. In arranging and syndicating
the Credit Facility, CIBC will be using and relying on the Information and the
Projections without independent verification thereof.

FEES AND EXPENSES; INDEMNITY

         In consideration of the commitments by CIBC hereunder, the Company
shall, upon acceptance of this Letter, pay to CIBC the fees set forth in and in
accordance with the separate Fee Letter from CIBC to the Company.

         In addition, and regardless of whether the transactions contemplated
hereunder are consummated, the Company agrees to pay the reasonable costs and
expenses (including the reasonable fees and expenses of external counsel
(including, without limitation, any local counsel) to CIBC, reasonable
professional fees of consultants, appraisers and other experts and reasonable
out-of-pocket expenses of CIBC, including, without limitation, syndication
expenses) incurred by CIBC in connection with the preparation, execution and
delivery of this Letter, the Fee Letter, the Senior Loan Documentation and the
syndication of the Credit Facility. Such expenses shall be due and payable upon
demand by CIBC or, at CIBC's discretion, shall be due and payable on the Closing
Date. The Company also agrees to pay all costs and expenses of CIBC (including,
without limitation, fees and disbursements of internal and external counsel)
incurred in connection with the enforcement of any of its rights and remedies
hereunder.

         The Company further agrees to indemnify, defend and hold harmless,
release and discharge each of the Lenders, CIBC, and each director, officer,
employee, agent, attorney and affiliate thereof (each an "indemnified person")
from and against any and all losses, claims, damages, liabilities or other
expenses to which CIBC or a Lender or such indemnified persons may become
subject, insofar as such losses, claims, damages, liabilities (or actions or
other proceedings commenced or threatened in respect thereof) or other expenses
arise out of or in any way relate to or result from the Transaction, any of the
statements contained in this Letter or relating to the extension of the
financing contemplated by this Letter, or any use or intended use of the
proceeds of any of the loans and other extensions of credit contemplated by this
Letter,

                                       4
<PAGE>

and to reimburse CIBC and each of the Lenders and each indemnified person for
any and all reasonable legal or other expenses incurred in connection with
investigating, defending or participating in any such investigation, litigation
or other proceeding (whether or not any such investigation, litigation or other
proceeding involves claims made between any Loan Party or any third party and
CIBC and such Lender or any such indemnified person, and whether or not such
Lender or any such indemnified person is a party to any investigation,
litigation or proceeding out of which any such expenses arise); PROVIDED,
HOWEVER, that the indemnity contained herein shall not apply to the extent that
such losses, claims, damages, liabilities or other expenses result from the
gross negligence or willful misconduct of CIBC, such Lender or indemnified
person, as determined by a final, non-appealable judgment of a court of
competent jurisdiction. Neither CIBC nor any Lender nor the Company shall be
responsible or liable to any other party or any other person for consequential
damages that may be alleged as a result of this Letter. The foregoing provisions
of this paragraph shall be in addition to any rights that CIBC, any Lender or
any indemnified person may have at common law or otherwise.

         All payments hereunder shall be made free and clear of any set-off,
withholding, claims or applicable taxes (other than taxes based on income) and
shall be made in U.S. dollars (unless otherwise specified).

         This provision shall survive termination of this Letter.

CONFIDENTIALITY

         The Company agrees that the existence of this Letter and the terms and
conditions hereof are confidential and may not be disclosed to any third party
without CIBC's prior written consent, except, after acceptance of this Letter,
to the extent that such disclosure (a) is required by law, regulation,
supervisory authority, or other applicable judicial or governmental order, (b)
was or becomes generally available to the public other than as a result of a
disclosure by one of the parties, (c) is made on a comparable confidential basis
to the attorneys, accountants and tax advisors of the Loan Parties on a need to
know basis. CIBC hereby consents to the disclosure of this Letter and the terms
and conditions hereof to the Company's underwriters in connection with the IPO
and agrees that the Company may file a copy of this Letter with the Securities
and Exchange Commission in connection with the Company's IPO.

         The Company acknowledges that CIBC may share with any of their
subsidiaries and affiliates (including CIBC Inc.) any information provided by
any Loan Party or any of their affiliates in connection with the proposed
Transaction, and that CIBC reserves the right to employ the services of such
subsidiaries and affiliates in order to fulfill their obligations under this
Letter.

         The Company should be aware that other parties with conflicting
interests may also be CIBC's customers, and that CIBC may be providing financial
or other services to them. However, CIBC assures that, consistent with their
long standing policy to hold in confidence the affairs of their customers, CIBC
will not furnish confidential information obtained from any Loan Party to any
other customer or prospective customer, and will hold such confidential
information in accordance with their customary procedures for handling
confidential

                                       5
<PAGE>

information. By the same token, CIBC will not make available to Veritas or any
Loan Party confidential information that CIBC has obtained from any other
customer.

         This provision shall survive the termination of this Letter.
