Agreement"), between EDO Corporation Employee Stock Ownership Plan (the
"ESOP"), and the Bank, the Bank has agreed to make a loan to the ESOP upon the
terms and subject to the conditions set forth therein, to be evidenced by the
Term Note issued by the ESOP thereunder;

loan to the ESOP under the Loan Agreement that the Guarantor shall have
executed and delivered this Guarantee to the Bank.

NOW, THEREFORE, in consideration of the premises and to induce the Bank to make
its loan to the ESOP under the Loan Agreement, the Guarantor hereby agrees with
the Bank as follows:

1. Defined Terms.  Unless otherwise defined herein (including in Schedule 1
hereto), terms which are defined in the Loan Agreement and used herein are so
used as so defined.  As used herein, "Obligations" shall mean the unpaid

Note, the Pledge Agreement or the Basic Documents and any other document made,
delivered or given in connection therewith, whether on account of principal,
interest, reimbursement obligations, fees, indemnities, costs, expenses
(including, without limitation, all fees and disbursements of counsel to the
Bank) or otherwise.

2. Guarantee.  The Guarantor hereby unconditionally and irrevocably guarantees
to the Bank the prompt and complete payment and performance by the ESOP when
due (whether at the stated maturity, by acceleration or otherwise) of the
Obligations.  The Guarantor further agrees to pay any and all expenses
(including, without limitation, all reasonable fees and disbursements of
counsel) which may be paid or incurred by the Bank in enforcing, or obtaining
advice of counsel in respect of enforcing, any of its rights under this
Guarantee.

make any payment to the Bank on account of its liability hereunder, it will
notify the Bank in writing that such payment is made under this Guarantee for
such purpose.  No payment or payments made by the ESOP or any other Person or
received or collected by the Bank from the ESOP or any other Person by virtue
of any action or proceeding or any set-off or appropriation or application, at
any time or from time to time, in reduction of or in payment of the
Obligations shall be deemed to modify, reduce, release or otherwise affect the
liability of the Guarantor hereunder which shall, notwithstanding any such
payment or payments, remain liable for the amount of the Obligations until the
Obligations are paid in full.

local for the ownership and operation of its business, and all proceeds of sale
thereof, (ii) all Inventory of such Guarantor held for sale or lease or to be

form satisfactory to the Bank) under the Uniform Commercial Code as the Bank
may specify, and will pay the cost of filing the same in such public offices as
the Bank shall designate.  Each Guarantor agrees to take whatever action the
Bank reasonably requests to perfect and to continue perfection of the Bank's
security interest in the Collateral.

efforts to cause the owners of the locations identified on Exhibit 2.1(f)

General Intangibles.  With respect to any Account, Chattel Paper, Instrument
and General Intangible that is Collateral hereunder, upon the occurrence and

all proceeds of the Accounts, Chattel Paper, Instruments and General
Intangibles payable to such Guarantor that may come to the Bank; (ii) notify

Guarantor's Accounts, Chattel Paper, Instruments and General Intangibles as the

Collateral; and (E) take control of any cash or non-cash proceeds of any

(f) Places of Business; Location of Collateral.  (i) The Guarantors represent
that (A) the properties listed on part A of Exhibit 2.1(f) attached hereto
serve as each Guarantor's chief place of business, chief executive office, and
the place where it keeps its Books and Records, and (B) all of the locations
where any one or more Guarantors keep Equipment or Inventory having an
aggregate value in excess of $1,000,000.00 are listed on part B of Exhibit
2.1(f) attached hereto.(ii) Each Guarantor will notify the Bank prior to (A)
any change in the location of the chief place of business or chief executive
office of such Guarantor, (B) any change in the place where such Guarantor
keeps its Equipment and/or Inventory or its Books and Records, (C) the
establishment of any new or the discontinuance of any existing place of
business of such Guarantor, and (D) the establishment of any new or the
discontinuance of any location where Inventory, Equipment or Books and Records

to be removed from its current location or any of their Inventory having an
aggregate value of $1,000,000.00 or more to be so removed without giving the
Bank prior written notice and then, only if and to the extent the Bank retains
a first priority, perfected security interest therein.

(g) Accounts.  With respect to each Account represented on EDO's Consolidated
balance sheet each Guarantor represents that:  (A) except as reflected on such
Consolidated balance sheet, such Account is not evidenced by a judgment, an
Instrument or Chattel Paper or secured by a letter of credit (except (1) such
judgment as has been assigned, (2) such Instrument or Chattel Paper as has been
endorsed and delivered to the Bank and (3) such letter of credit as has been
assigned and delivered to the Bank) and represents a bona fide completed
transaction; (B) except as reflected on such Consolidated balance sheet, the
amount shown on such Guarantor's Books and Records and on any list, invoice or
statement furnished to the Bank is owing to such Guarantor; (C) such Guarantor
has good title to the Account free and clear of all liens and encumbrances
except for Permitted Encumbrances; (D) the Account has not been transferred to
any other Person, and, at the time such Account is created, no person except
such Guarantor or Purchaser has any claim thereto or to the goods or services
represented thereby; (E) except as reflected on such Consolidated balance
sheet, no partial payment against any Account has been made by anyone other
than as noted on such Guarantor's Books and Records and (F) except as reflected
on such Consolidated balance sheet, to the best of such Guarantor's knowledge,
except as reflected on such Consolidated balance sheet, no set-off or counter
claim to such Account exists, and no agreement has been made with any person
under which any deduction or discount may be claimed.  The Guarantors shall be
deemed not to have made a misrepresentation with respect to this Section 2.1(g)
unless such representation would constitute a misrepresentation under Section
3.7(A) of the Revolving Credit Loan Agreement.  The Guarantors will promptly
notify the Bank if any Account arises out of contracts with the United States,
any United States state, territory or local government or any department,
agency or instrumentality thereof, furnish the Bank with copies of each such
contract, at the Bank's request, and execute any instruments and take any steps
in order that (subject to the following sentence) all moneys due and to become
due under any such contract shall be assigned to the Bank and notice given
under the Federal Assignment of Claims Act (or applicable state statute, if
any).  The Bank agrees not to deliver any such notices or assignments to the
applicable United States or other United States state, territory or local
governmental department, agency or instrumentality unless and until there
occurs a Guarantee Event of Default and then the Bank shall deliver such
notices of assignment only if it determines in good faith that under the
circumstances it is reasonable to do so to protect its rights in and to such
Accounts or the proceeds thereof or in anticipation of exercising its rights
hereunder as a result of such Guarantee Event of Default.  Each Guarantor will
(i) if requested by the Bank, furnish to the Bank copies, with such duplicate
copies as the Bank may request, of any invoice applicable to each of its
Accounts; (ii) inform the Bank immediately of any delay in performance by such
Guarantor or claims made in regard to its Accounts which alone or in the
aggregate with other claims or delays could likely have a Material Adverse
Effect; and (iii) furnish the Bank with such other reports as the Bank may from
time to time reasonably request.

(h) Chattel Paper; Letters of Credit and Instruments.  Each Guarantor covenants
that it will deliver to the Bank promptly all copies (or if requested by the
Bank, all originals) of (i) all letters of credit securing Accounts except to
the extent, permitted under the Revolving Credit Loan Agreement, (ii) Chattel
Paper, and/or (iii) Instruments now in its possession or hereafter acquired,
each properly assigned and/or endorsed over to the Bank, the originals which
letters of credit, Chattel Paper and Instruments delivered to the Bank shall be
held by the Bank as security hereunder.  The Guarantors shall remain solely
responsible for the observance and performance of all of its or their covenants
and obligations under all Chattel Paper and Instruments, and the Bank shall not
be required to observe or perform any such covenants or obligations.

(i) Equipment.  Each Guarantor represents, warrants and agrees that (i) such
Guarantor has good title to its Equipment (other than leased Equipment),
subject only to the security interests created hereby and Permitted
Encumbrances; and (ii) such Guarantor will not dispose of any of its Equipment
other than in the ordinary course of business and then in accordance with the
terms of this Agreement, or permit any of its Equipment to become a fixture or
an accession to other property unless the Bank's security interest therein
would continue to be a perfected, first lien priority security interest
therein.

(j) Expenses of Bank.  The Guarantors will reimburse the Bank within ten (10)
days after demand for all reasonable expenses (including the reasonable fees
and expenses of legal counsel for the Bank) in connection with the enforcement
of the Bank's rights to take possession of the Collateral and the proceeds
thereof and to hold, collect, render in compliance with applicable laws and
regulations (including without limitation Environmental Laws), prepare for
sale, sell and dispose of the Collateral.

(k) Notices.  If notice of sale, disposition or other intended action by the
Bank with respect to the Collateral is required by the U.C.C. or other
applicable law, any notice thereof sent to the appropriate Guarantor at its
address listed herein or such other address of such Guarantor as may from time
to time be shown on the records of the Bank at least ten days prior to such
action, shall constitute reasonable notice to such Guarantor.

(l) Insurance; Discharge of Taxes, etc.  The Bank shall have the right at any
time and from time to time, with or without notice to any Guarantor, to (i)
obtain insurance covering any of the Collateral if the appropriate Guarantor
fails to do so, (ii) discharge taxes, liens, security interests or other
encumbrances at any time levied or placed on any of the Collateral and (iii)
pay for the maintenance and preservation of any of the Collateral.  The
Guarantors will reimburse the Bank, on demand, with interest thereon at the
Default Rate for any payment the Bank makes, or any reasonable expense the Bank
incurs under this authorization.  Each Guarantor assigns to the Bank all rights
to receive the proceeds of insurance covering the Collateral.  If there exists
a Guarantee Event of Default and an acceleration of the Term Note, the
Guarantors authorize the Bank to apply such proceeds as a prepayment of the
Term Note, subject to the Agent's pari passu rights under the Revolving Credit
Loan Agreement, and as set forth in the Intercreditor Agreement.  In the event
that there does not exist a Guarantee Event of Default and an acceleration of
the Term Note, such proceeds shall be subject to Section 2.6 of the Revolving
Credit Loan Agreement.  If the Revolving Credit Loan Agreement has been
terminated and all of EDO's obligations thereunder have been discharged in full
and there does not exist a Guarantee Event of Default and an acceleration of
the Term Note, at the Guarantor's written request , the Bank shall make such
proceeds available to such Guarantor for the repair or replacement of damaged
Collateral if and on condition that (A) such Guarantor proceeds diligently to
cause such replacement and/or repair, and (B) any excess proceeds remaining
after such repair and/or replacement shall be applied by the Bank as a
prepayment of the Term Note.

(m) Waiver and Release by the Guarantors.  Each Guarantor (i) waives protest of
all commercial paper at any time held by the Bank on which such Guarantor is in
any way liable, notice of nonpayment at maturity of any and all Accounts and,
except where required hereby or by law, notice of action taken by the Bank
under any of the Basic Documents, and (ii) releases the Bank from all claims
for loss or damage caused by any failure to collect any Account or by any act
or omission on the part of the Bank or its officers, agents and employees,
except to the extent resulting from the willful misconduct or gross negligence
as determined in a final judgment of a court of competent jurisdiction or a
settlement tantamount to such formal order.

(n) Records and Reports.  Each Guarantor shall keep accurate and complete
records of its Accounts (and the collection thereof), General Intangibles,
Chattel Paper, Instruments, Documents and Inventory and furnish the Bank such
information about its Accounts, General Intangibles, Chattel Paper,
Instruments, Documents, and Inventory as the Bank may reasonably request.  The
Bank shall have the right to conduct periodic examinations and verifications of
such Guarantor's Books and Records, which examination may include, without
limitation, verifications of Accounts by contacting Purchasers; provided that
if there then exists no Guarantee Event of Default, the Bank shall conduct such
verifications with such Guarantor's assistance (which such Guarantor agrees to
provide) using such Guarantor's letterhead with responses to be returned to a
lock box under the Bank's control.  Each Guarantor agrees to make its Books and
Records available to the Bank at such Guarantor's principal place of business
for purposes of such examination.  Provided there does not exist a Guarantee
Event of Default, the Bank agrees to give such Guarantor at least two (2)
Business Days prior notice of such examination (which notice need not be in
writing) and to conduct such examination during normal business hours.  The
Guarantors shall reimburse the Bank for the reasonable costs and expenses of
any such examination conducted following the occurrence and during the
continuation of a Guarantee Event of Default.

(o) Further Assurances.  From time to time the Guarantors will execute and
deliver to the Bank such additional instruments as the Bank may reasonably
request to effectuate the purposes of this Agreement and to assure to the Bank,
as secured party, a perfected, first priority security interest in the
Collateral.

(p) Application of Proceeds of Collateral.  After the occurrence of a Guarantee
Event of Default, all proceeds of Collateral shall be applied (i) to the costs
of preservation and liquidation of such Collateral and the Bank's exercise of
its rights hereunder then (ii) to all other Guarantee Liabilities.

(q) Continuing Collateral.  The Bank shall be under no obligation to proceed
first against (a) any part of the Collateral before proceeding against any
other part of the Collateral, (b) any Guarantor before any other Guarantor.  It
is expressly agreed that all of the Collateral stands as equal security for all
Guarantee Liabilities and the other obligations of the Guarantors hereunder and
the Bank shall have the right to proceed against or sell any and/or all of the
Collateral in any order, or simultaneously, as it, in its sole discretion,
shall determine.

(r) Section 8 of the Guarantee is hereby amended by deleting the address of the
Bank set forth therein and substituting, in lieu thereof , the following:
"1735 Market Street, Philadelphia, PA 19101."

3. Right of Set-off.  The Bank is hereby irrevocably authorized at any time and
from time to time without notice to the Guarantor, any such notice being hereby
waived by the Guarantor, to set off and appropriate and apply 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, at any time held or owing by the Bank to
or for the credit or the account of the Guarantor, or any part thereof in such
amounts as the Bank may elect, on account of the liabilities of the Guarantor
hereunder and claims of every nature and description of the Bank against the
Guarantor, in any currency, whether arising hereunder, under the Loan
Agreement, the Term Note, any other Basic Document, or otherwise in connection
herewith, as the Bank may elect, whether or not the Bank has made any demand
for payment.  The Bank shall notify the Guarantor promptly of any such set-off
and the application made by the Bank of the proceeds thereof, provided that the
failure to give such notice shall not affect the validity of such set-off and
application.  The rights of the Bank under this paragraph are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which the Bank may have.

4. No Subrogation.  Notwithstanding any payment or payments made by the
Guarantor hereunder, or any set-off or application of funds of the Guarantor by
the Bank, the Guarantor shall not be entitled to be subrogated to any of the
rights of the Bank against the ESOP or against any collateral security or
guarantee or right of offset held by the Bank for the payment of the
Obligations, nor shall the Guarantor seek any reimbursement from the ESOP in
respect of payments made by the Guarantor hereunder, until all amounts owing to
the Bank by the ESOP on account of the Obligations are paid in full.  If any
amount shall be paid to the Guarantor on account of such subrogation rights at
any time when all of the Obligations shall not have been paid in full, such
amount shall be held by the Guarantor in trust for the Bank, segregated from
other funds of the Guarantor, and shall, forthwith upon receipt by the
Guarantor, be turned over to the Bank in the exact form received by the
Guarantor (duly indorsed by the Guarantor to the Bank, if required), to be
applied against the Obligations, whether matured or unmatured, in such order as
the Bank may determine.

5. Amendments, etc. with respect to the Obligations.  The Guarantor shall
remain obligated hereunder notwithstanding that, without any reservation of
rights against the Guarantor, and without notice to or further assent by the
Guarantor, any demand for payment of any of the Obligations made by the Bank
may be rescinded by the Bank, and any of the Obligations continued, and the
Obligations, or the liability of any other party upon or for any part thereof,
or any collateral security or guarantee therefor or right of offset with
respect thereto, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Bank, and the Loan Agreement, the Term Note, the Pledge
Agreement or any other Basic Document and any other document in connection
therewith may be amended, modified, supplemented or terminated, in whole or in
part, as the Bank may deem advisable from time to time, and any collateral
security, guarantee or right of offset at any time held by the Bank for the
payment of the Obligations may be sold, exchanged, waived, surrendered or
released.  The Bank shall have no obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Obligations or for
this Guarantee or any property subject thereto.

6. Guarantee Absolute and Unconditional.  The Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance by the Bank upon this Guarantee or
acceptance of this Guarantee; the Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred in reliance
upon this Guarantee; and all dealings between the ESOP or the Guarantor, on the
one hand, and the Bank, on the other, shall likewise be conclusively presumed
to have been had or consummated in reliance upon this Guarantee.  The Guarantor
waives diligence, presentment, protest, demand for payment and notice of
default or nonpayment to or upon the ESOP or the Guarantor with respect to the
Obligations.  This Guarantee shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity or
enforceability of the Loan Agreement, the Term Note, the Pledge Agreement, or
any other Basic Document, any of the Obligations or any collateral security
therefor or guarantee or right of offset with respect thereto at any time or
from time to time held by the Bank, (b) any defense, set-off or counterclaim
(other than a defense of payment or performance) which may at any time be
available to or be asserted by the ESOP against the Bank, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the ESOP or
the Guarantor) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the ESOP for the Obligations, or of the
Guarantor under this Guarantee, in bankruptcy or in any other instance.  When
pursuing its rights and remedies hereunder against the Guarantor, the Bank may,
but shall be under no obligation to, pursue such rights and remedies as it may
have against the ESOP or any other Person or against any collateral security or
guarantee for the Obligations or any right of offset with respect thereto, and
any failure by the Bank to pursue such other rights or remedies or to collect
any payments from the ESOP or any such other Person or to realize upon any such
collateral security or guarantee or to exercise any such right of offset, or
any release of the ESOP or any such other Person or any such collateral
security, guarantee or right of offset, shall not relieve the Guarantor of any
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Bank against
the Guarantor.

7. Reinstatement.  This Guarantee shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Obligations is rescinded or must otherwise be restored or returned
by the Bank upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the ESOP or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
ESOP or any substantial part of its property, or otherwise, all as though such
payments had not been made.

8. Payments.  The Guarantor hereby agrees that the Obligations will be paid to
the Bank without set-off or counterclaim in U.S.  Dollars at the office of the
Bank located at 270 Park Avenue, New York, New York 10017.

9. Representations and Warranties.  The Guarantor represents and warrants that:

existing and in good standing under the laws of the jurisdiction of its
incorporation, has the corporate power to own its assets and to transact the
business in which it is presently engaged, is duly qualified as a foreign
corporation 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 is in compliance with all Requirements of Law
except to the extent that the failure to so qualify or comply therewith could
not have a material adverse effect on the business, operations, property or
financial or other condition of the Guarantor and its Subsidiaries taken as a
whole.

(b) the Guarantor has the corporate power, authority and legal right to make,
deliver and perform the Basic Documents to which it is a party and has taken

performance of the Basic Documents to which it is a party.  No consent of any
other Person, and no consent, license, permit, approval or authorization of,
exemption by, notice or report to, or registration, filing or declaration with,
any Governmental Authority is required in connection with the execution,
delivery, performance, validity or enforceability of the Basic Documents to
which it is a party.

(c) the execution, delivery and performance by the Guarantor of the Basic
Documents to which it is a party will not violate any Requirement of Law or any
Contractual Obligation of the Guarantor and will not result in, or require, the
creation or imposition of any Lien on any of its property, assets or revenues
pursuant to any Requirement of Law or Contractual Obligation.

(d) there is no litigation, investigation or other proceeding of or before any
arbitrator or Governmental Authority pending or threatened against the
Guarantor or any of its Subsidiaries or any of its or their assets or with
respect to the Basic Documents or any of the transactions contemplated thereby,
which, if adversely determined, would have a material adverse effect on the
business, assets or financial condition of the Guarantor and its Subsidiaries
taken as a whole.

(e) the Basic Documents to which the Guarantor is a party have been duly
executed and delivered on behalf of the Guarantor and constitute legal, valid
and binding obligations of the Guarantor enforceable against the Guarantor in
accordance with their respective terms except as such enforcement may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally.

(f) (i) the ESOP is a trust duly existing under the laws of the State of New
York and is a stock bonus plan qualified under Section 401(a) of the Code and
the provisions of the ESOP satisfy the requirements for employee stock
ownership plans set forth in Section 4975(e)(7) of the Code.  The Trustee
executing the Basic Documents on behalf of the ESOP has adequate authority to
do so under the ESOP's organizational documents.  No "prohibited transaction"
under ERISA or the Code has occurred with respect to the ESOP or will occur
upon the execution of the Term Note or the other Basic Documents;

(ii) the ESOP has the power, authority and legal right to make, deliver and
perform the Basic Documents to which it is a party and to borrow under the Loan

legal, valid and binding obligations of the ESOP enforceable against the ESOP
in accordance with their respective terms except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally;

(iii) the execution, delivery and performance by the ESOP of the Basic
Documents to which it is a party, the borrowings and the use of the proceeds
thereof will not violate any Requirement of Law or any Contractual Obligation
of the ESOP and will not result in, or require, the creation or imposition of
any Lien on any of its property, assets or revenues pursuant to any Requirement
of Law or Contractual Obligation;

(iv) no litigation, investigation or other proceeding of or before any
arbitrator or Governmental Authority is pending or, to the knowledge of the
Guarantor, threatened against the Trustee or the ESOP or any of the assets of
the ESOP (a) with respect to the Basic Documents or any of the transactions
contemplated thereby, or (b) which, if adversely determined, would have a
material adverse effect on the business, assets or financial condition of the
ESOP;

(v) the ESOP is not in default in the payment or performance of any of its
Contractual Obligations in any respect which could be materially adverse to the
business, operations, property or condition (financial or otherwise) of the
ESOP or which could materially adversely affect the ability of the ESOP to
perform its obligations under any of the Basic Documents to which it is a
party.  No Default or Event of Default has occurred and is continuing.  The
ESOP is not in default under any order, award or decree of any arbitrator or
Governmental Authority binding upon or affecting it or by which any of its
assets may be bound or affected, and no such order, award or decree materially

of the Basic Documents to which it is a party;

(vi) the Term Loan is an exempt loan within the meaning of Treasury Regulation
Section 54.4975-7(b)(1)(iii).  Neither the Term Loan nor the taking of any
action contemplated by the Basic Documents is a "prohibited transaction" within
the meaning of Section 4975 of the Code or Sections 406 and 408 of ERISA, or
violates any provision of the ESOP; and

(vii) the ESOP has filed copies of all statements and reports which are
required to be filed with any Governmental Authority, except to the extent that

payment or performance of any Contractual Obligations in any respect which
could be materially adverse to the business, operations, property or condition
(financial or otherwise) of the Guarantor and its Subsidiaries taken as a whole
or which could materially adversely affect the ability of the Guarantor to
perform its obligations under any of the Basic Documents to which it is a
party, (b) no Guarantee Event of Default hereunder and no Default or Event of
Default under any of the Basic Documents has occurred and is continuing and (c)
neither the Guarantor nor any of its Subsidiaries is in default under any
order, award or decree of any Governmental Authority binding upon or affecting
the Guarantor or any of its Subsidiaries, and no such order, award of decree
materially adversely affects the ability of the Guarantor to perform its
obligations under any of the Basic Documents to which it is a party.

(h) all of the shares of the Pledged Stock (as defined in the Pledge Agreement)
have been duly and validly issued and are fully paid and non-assessable.
Assuming that the Bank or its duly appointed agent therefor obtains and
maintains continuous possession of the Pledged Stock, the Pledge Agreement
creates in favor of the Bank a first priority security interest in such Pledged
Stock, and the proceeds thereof, pledged thereunder.

an "investment company" (as each of the quoted terms is defined or used in the
Investment Company act of 1940, as amended).

(k) the consolidated balance sheet of the Guarantor and its Subsidiaries as at
December 31, 1987 and the related consolidated statement of income and retained
earnings for the fiscal year then ended (copies of which have heretofore been
furnished to the Bank) have been prepared in accordance with GAAP applied
consistently throughout the period involved, are complete and correct and
present fairly the consolidated financial condition of the Guarantor and its
Subsidiaries as at such date and the results of their operations for such
fiscal year; since such date there has been no material adverse change in the
business, operations, property or financial or other condition of the Guarantor
and its Subsidiaries taken as a whole.  Neither the Guarantor nor izs
Subsidiaries has any material Contingent Obligation, contingent liability or
liability for taxes, long-term lease or unusual forward or long-term commitment
which is not reflected in the foregoing statements or in the notes thereto.
