          WHEREAS, the respective Boards of Directors of Buyer and the Company
have approved the merger of Buyer with and into the Company (the "MERGER"), upon
the terms and subject to the conditions set forth herein.

          WHEREAS, Buyer is unwilling to enter into this Agreement unless,

enter into a Voting Agreement and Messrs. Peacock and Howley enter into an
agreement in the form of Exhibit A hereto and such persons have agreed to enter

hereof, at the Effective Time (as defined in Section 1.3), Buyer shall be merged
with and into the Company and the separate existence of Buyer shall thereupon
cease, and the Company shall continue as the surviving corporation in the Merger
(the "SURVIVING CORPORATION") under the laws of the State of Delaware.

          1.2  CLOSING .  Unless this Merger Agreement shall have been
terminated pursuant to Section 8.3, and subject to the satisfaction or waiver of
the conditions set forth in Section 7, the closing of the Merger will take place
as promptly as practicable (and in any event within two business days) after
satisfaction or waiver of the condition set forth in Section 7.2.1, at the New
York offices of Latham & Watkins unless another date, time or place is agreed to
in writing by the parties hereto (the "CLOSING DATE").

          1.3  EFFECTIVE TIME OF THE MERGER .  The Merger shall become effective
upon the filing of a Certificate of Merger with the Secretary of State of

the Effective Time any


                                          5


further action is necessary to vest in the Surviving Corporation the title to
any property or rights of Buyer or the Company, the proper officers and
directors of the Surviving Corporation shall be fully authorized in the name of
each of Buyer or the Company, as the case may be, to take any and all such
lawful action.

          2.  THE SURVIVING CORPORATION.

          2.1  CERTIFICATE OF INCORPORATION .  The Certificate of Incorporation

prior to the Effective Time shall be the By-laws of the Surviving Corporation,
until thereafter changed or amended as provided therein or by applicable law.

          2.3  DIRECTORS .  The directors of Buyer immediately prior to the

or Buyer:

          (a)  The shares of Common Stock, par value $.01 per share, of Buyer
     issued and outstanding immediately prior to the Effective Time shall
     automatically be converted into and thereafter represent a number of
     validly issued, fully paid and non-assessable shares of common stock, par
     value $.01 per share, of the Surviving Corporation (the "SURVIVING
     CORPORATION COMMON STOCK") equal to the quotient of the Odyssey Equity
     Investment divided by the Per Share Merger Consideration.

          (b)  All shares of Common Stock, $.01 par value, of the Company
     ("VOTING COMMON STOCK") and all shares of Class A Common Stock, $.01 par
     value, of the Company ("NONVOTING COMMON STOCK," and together with Voting
     Common Stock, "COMMON STOCK") which are held by the Company shall be
     cancelled and retired and shall cease to exist, and no consideration shall
     be delivered in exchange therefor.

          (c)  Each share of Common Stock issued and outstanding immediately
     prior to the Effective Time, other than those to which Section 3.1(b) or
     Section 3.1(d) applies


                                          6


     and other than any shares held by stockholders referred to in Section
     3.1(g), shall be converted into and represent the right to receive an
     amount in cash (such amount in cash being referred to herein as the "PER
     SHARE MERGER CONSIDERATION") equal to the quotient of (A) the Merger
     Consideration PLUS the Aggregate Exercise Proceeds PLUS the Option Rollover
     Amount, PLUS the Kelso Rollover Amount, MINUS the Transaction Costs divided
     by (B) the total number of Outstanding Shares. 

          The following terms used in the definition of Per Share Merger

          "AGGREGATE EXERCISE PROCEEDS" means the aggregate exercise price
     payable upon exercise of the Options (as defined below in Section 3.1(e))
     which are to be cancelled pursuant to Section 3.1(e) hereof and all of the
     Warrants (as defined below in Section 3.1(f)).

          "OPTION ROLLOVER AMOUNT" means the gross amount of the Options listed
     on Schedule 3.1(e).

          "KELSO  ROLLOVER AMOUNT" means (A) the quotient of the Odyssey Equity
     Investment Amount divided by .925 MINUS (B) the Odyssey Equity Investment
     Amount.

          "TRANSACTION COSTS" means the fees and expenses listed on Schedule
     3.1(c).

          "OUTSTANDING SHARES" means 303,294.4 (the number of shares of common
     stock of the Company on a fully-diluted basis).

          "ODYSSEY EQUITY INVESTMENT AMOUNT" shall equal $90 million or such
     other amount invested by Odyssey in the Buyer immediately prior to the
     Effective Time but in no event shall such amount exceed $100 million
     without the Company's consent in its sole discretion.

          (d)  A number of shares of Common Stock held by Kelso Investment
     Associates IV, L.P. ("KIA IV") and Kelso Equity Partners II, L.P. ("KEP
     II") equal to the quotient of the Kelso Rollover Amount divided by the Per
     Share Merger Consideration (each, a "ROLLOVER SHARE") shall be converted
     into and become one fully paid and nonassessable share of common stock,
     $.01 par value, of the Surviving Corporation. Such conversion shall be
     effected such that KIA IV and KEP II will own 94.39% and 5.61% of such
     Rollover Shares, rounded to the nearest whole share; provided that in no
     event shall the number of Rollover Shares exceed the amount equal to the
     quotient of the Kelso Rollover Amount divided by the Per Share Merger 



                                          7


     Consideration.  All Rollover Shares shall be subject to the stockholders
     agreement referred to in Sections 7.3.5 and 7.4.10.

          (e)  Each outstanding option to purchase shares of Common Stock
     granted under the Company's 1994 Stock Incentive Plan (each, an "OPTION")
     to any current or former employee of the Company or any subsidiary thereof
     (each, an "OPTION HOLDER"), whether or not then exercisable, shall be
     cancelled and, in exchange therefor, each Option Holder shall be entitled
     to a cash payment (the "OPTION CANCELLATION PAYMENT") in respect of each
     such cancelled Option held by each such Option Holder equal to the product
     of (I) the number of shares of Common Stock covered by such Option
     immediately prior to the Effective Time multiplied by (II) the excess of
     (X) the Per Share Merger Consideration over (Y) the per share exercise
     price under such Option (the "NET VALUE"); PROVIDED, HOWEVER, that with
     respect to the individuals listed on Schedule 3.1(e) the Options held by
     each such individual shall be cancelled only to the extent from and after
     the Effective Time each such individual shall retain Options with an
     aggregate Net Value not less than the amount set forth opposite such
     person's name on Schedule 3.1(e).   From and after the Effective Time,
     pursuant to the terms of such stock option agreements, each such Option not
     cancelled shall represent an option to purchase an equal number of shares
     of Surviving Corporation Common Stock.  Schedule 3.1(e) may be changed from
     time to time to add additional optionholders or to increase the net amount
     of any Options not being cancelled.  The Option Cancellation Payments shall
     be subject to all applicable withholding and employment taxes and shall be
     paid to the Option Holders as soon as practicable following the Effective
     Time.  Prior to the Effective Time, the Board of Directors shall adopt such
     resolutions or take such actions as are necessary, subject if necessary, to
     obtaining the consents of the holders thereof, to carry out the terms of
     this Section 3.1(e).

          (f)  Each warrant to purchase shares of Common Stock granted under the
     Company's Warrant Agreement (the "WARRANT AGREEMENT"), dated September 30,
     1993 (each, a "WARRANT"), to any person (each, a "WARRANT HOLDER"), shall
     be cancelled and, in exchange therefor, each Warrant Holder shall be
     entitled to a cash payment (the "WARRANT CANCELLATION PAYMENT") in respect
     of each such cancelled Warrant equal to the product of (I) the number of
     shares of Common Stock covered by such Warrant immediately prior to the
     Effective Time multiplied by (II) the excess of (X) the Per Share Merger
     Consideration over (Y) the per share exercise price under such Warrant. 
     Prior to the Effective Time, the Board of Directors shall adopt such
     resolutions or take such actions as are necessary, subject to obtaining the
     consents of the holders thereof, to carry out the terms of this Section
     3.1(f).

          (g)  Notwithstanding anything to the contrary herein, shares of Common
     Stock held by stockholders who dissent from the Merger pursuant to Section
     262 of the DGCL shall not be converted as of the Effective Time into a
     right to receive the Per


                                          8


     Share Merger Consideration, but instead shall have such rights as may be
     available under the DGCL.

          3.2  PAYMENT .  (a)  Pursuant to an agreement in form and substance
acceptable to the Company to be entered into prior to the Effective Time between
Buyer and a disbursing agent reasonably satisfactory to Buyer and the Company
(the "DISBURSING AGENT"), at the Effective Time, Buyer shall make available to
the Disbursing Agent the Merger Consideration MINUS the Transaction Costs (the
"PAYMENT FUND").  All payments for shares of Common Stock, Options and Warrants
which are made in accordance with the terms hereof shall be deemed to have been
made in full satisfaction of all rights pertaining to such shares, Options and
Warrants, as the case may be.

          (b)  Promptly after the Effective Time, Buyer shall cause the
Disbursing Agent to send a notice and a letter of transmittal to each holder of
certificates formerly evidencing (I) shares of Common Stock (other than
certificates representing Rollover Shares, shares of Common Stock to be
cancelled pursuant to Section 3.1(b) and held by stockholders referred to in
Section 3.1(g) (the "DISSENTING SHARES"), (II) Options to be cancelled pursuant
to Section 3.1(e) and (III) Warrants (collectively, the "CERTIFICATES") advising
holders of such Certificates of the effectiveness of the Merger and the
procedure for surrendering to the Disbursing Agent such Certificates for
exchange into the Per Share Merger Consideration, the Option Cancellation
Payment or the Warrant Cancellation Payment, as the case may be, and that
delivery shall be effected, and risk of loss and title shall pass, only upon
proper delivery to the Disbursing Agent of the Certificates and a duly executed
letter of transmittal and any other required documents of transfer.  Each holder
of the Certificates, upon surrender thereof to the Disbursing Agent together
with such letter of transmittal (duly executed) and any other required documents
of transfer, shall be entitled to receive in exchange therefor the Per Share
Merger Consideration, the Option Cancellation Payment or the Warrant
Cancellation Payment, as the case may be.  Upon such surrender, the Disbursing
Agent shall promptly deliver the merger consideration due hereunder (less any
applicable withholding tax) in accordance with the instructions set forth in the
related letter of transmittal, and the Certificates so surrendered shall
promptly be cancelled.  Until surrendered, the Certificates (other than those
evidencing Dissenting Shares) shall be deemed for all purposes to evidence only
the right to receive the merger consideration due hereunder, or, in the case of
Dissenting Shares, the fair value of such Dissenting Shares.  No interest shall
accrue or be paid on any cash payable upon the surrender of the Certificates
(other than Dissenting Shares to the extent required by the DGCL).

          (c)  If the merger consideration due hereunder is to be delivered to a
person other than the person in whose name the Certificates surrendered in
exchange therefor are registered, it shall be a condition to the payment of such
merger consideration that the Certificates so surrendered shall be properly
endorsed or accompanied by appropriate powers and otherwise in proper form for
transfer, that such transfer otherwise be proper and that the person requesting
such transfer pay to the Disbursing Agent any transfer or


                                          9


other taxes payable by reason of the foregoing or establish to the satisfaction
of the Disbursing Agent that such taxes have been paid or are not required to be
paid.

          (d)  Unless required otherwise by applicable law, any portion of the
Payment Fund that remains undistributed to holders of the Certificates 180 days
after the Effective Time shall be delivered to the party who provided such funds
to the Disbursing Agent and any Certificate holder who has not theretofore
complied with the provisions of this Section 3 shall thereafter look only to the
Surviving Corporation for payment of any merger consideration due hereunder, to
which he is entitled pursuant to this Section 3.  Neither Buyer nor the
Disbursing Agent shall be liable to any such Certificate holder for any cash
from the Payment Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

          3.3  NO FURTHER RIGHTS .  From and after the Effective Time, holders
of certificates theretofore evidencing shares of Common Stock, other than
Rollover Shares, shall cease to have any rights as stockholders of the Company,
except as provided herein or by law.

          3.4  CLOSING OF THE COMPANY'S TRANSFER BOOKS .  At the Effective Time,
the stock transfer books of the Company shall be closed and no transfer of
shares of Common Stock shall be made thereafter.  If after the Effective Time
certificates for shares of Common Stock are presented to Buyer or the Surviving
Corporation, they shall be cancelled and exchanged as provided in this Section
3.

          4.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
represents and warrants to Buyer as follows, except as set forth in the
schedules delivered by the Company to Buyer on or prior to the date of execution
of this Merger Agreement:

          4.1  CORPORATE STATUS AND AUTHORITY .  The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware and is duly qualified to do business as a foreign corporation
in the jurisdictions in which the Company conducts its business, except where
the failure to so qualify will not have a Material Adverse Effect (as defined
below) on the Company and has the corporate power and authority to execute and
deliver this Merger Agreement and perform its obligations hereunder and to
conduct its business and to own, use or lease its properties and assets as now
conducted, owned, used or leased.  The execution and delivery of this Merger
Agreement and the consummation of the transactions contemplated hereby by the
Company have been duly and validly authorized and approved by the Company's
Board of Directors and by the holders of the required percentage of Common Stock
and no other corporate or stockholder proceedings on the part of the Company are
necessary to authorize or approve this Merger Agreement or to consummate the
transactions contemplated hereby.  This Merger Agreement has been duly executed
and delivered by the Company, and assuming the due authorization, execution and
delivery by Buyer, constitutes the valid and binding obligation of the


                                          10


Company enforceable against the Company in accordance with its terms, except as
such enforceability may be limited by general principles of equity or principles
applicable to the enforcement of creditors rights generally.  The Company has
delivered to Buyer true, correct and complete copies of its and its
subsidiaries' certificates of incorporation and by-laws (in each case, as
amended to date).  The Company and its subsidiaries are not in default or in
violation of any provision of their certificates of incorporation or by-laws. 
For the purposes of this Merger Agreement, "MATERIAL ADVERSE EFFECT" or a
similar phrase shall mean, with respect to any person, any material adverse
effect on (I) the business, operations, assets (taken as a whole), liabilities
(taken as a whole), financial condition or results of operations of such person
and its subsidiaries, taken as a whole or, (II) the right or ability of such
person or its subsidiaries to consummate any of the transactions contemplated
hereby.  "MATERIAL ADVERSE CHANGE" shall have a corresponding definition.

          4.2  NO CONFLICTS; CONSENTS AND APPROVALS, ETC.   (a)  Except as set
forth in Schedule 4.2(a), the execution and delivery of this Merger Agreement
and the performance of its obligations hereunder will not result in (I) any
conflict with the certificate of incorporation or by-laws of the Company or any
of its subsidiaries, (II) subject to obtaining the consents referred to in
Section 4.2(b), any breach or violation of or default under (A) any law,
statute, regulation, rule, judgment, order, decree, license, permit or other
governmental authorization or (B) any Contract (as defined), mortgage, lease,
agreement, deed of trust, indenture or any other instrument, in each case, to
which the Company or any of its subsidiaries is a party or by which any of them
or their respective properties or assets are bound, or (III) the creation or
imposition of any liens, security interests, adverse claims, charges or
encumbrances ("LIENS") other than Liens created by or resulting from the actions
of Buyer or any of its affiliates, except, in the case of subsections (ii) and
(iii), for such breaches, violations or defaults and such Liens which would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company.

          (b)  Except as set forth in Schedule 4.2(b), no consent, approval or
authorization of or filing with any third party or any governmental authority is
required on the part of the Company or any of its subsidiaries in connection
with the execution and delivery of this Merger Agreement or the consummation of
the transactions contemplated hereby, except (I) filings required with respect
to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR ACT") and
(II) filings, consents or approvals which, if not made or obtained, would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company.

          4.3  CAPITALIZATION .  The authorized capital stock of the Company
consists of 900,000 shares of Voting Common Stock, par value $0.01 per share,
236,120 of which shares are issued and outstanding and 100,000 shares of
Nonvoting Common Stock, par value $0.01 per share, 13,750 of which are issued

forth on Schedule 4.3, there are no shareholder agreements, voting trusts,
proxies or other agreements or understandings with respect to the voting of any
Equity Securities in the Company.  The only indebtedness for borrowed money is
the Amended and Restated Credit Agreement, dated as of August 8, 1997, among
TransDigm Inc., the Lenders named therein, the Chase Manhattan Bank as
Administrative Agent, Collateral Agent and Issuing Bank, and Chase Securities
Inc. as Arranger (the "CREDIT AGREEMENT").  The Credit Agreement is prepayable

calls, warrants, options or commitments of any kind or character relating to, or
entitling any person or entity to purchase or otherwise acquire, any capital

authorized and validly issued and are fully paid and non-assessable.  Except as
set forth in Schedule 4.5, there are no outstanding Equity Securities or other
rights, obligations, commitments or agreements of any kind for the purchase,
redemption or acquisition from, or the sale or issuance by, the Company or any
of its subsidiaries of any Equity Securities of any of such subsidiaries, and no
authorization therefor has been given.  The Company does not have any equity
interest or investment in any corporation, partnership, joint venture,
association or other business organization other than as set forth on Schedule
4.5.  There are no shareholder agreements, voting trusts, proxies or other
agreements or understandings with respect to the voting of any Equity Securities
in any subsidiaries of the Company.

          (b)  Each of the Company's subsidiaries is a corporation duly
incorporated, validly existing and in good standing under the laws of the state
of its incorporation,


                                          12


which is set forth on Schedule 4.5, and has all requisite corporate power and
authority to conduct its business and to own, use or lease its properties and
assets, as now conducted, owned, used or leased, and is duly qualified to do
business in each jurisdiction in which the failure to be so qualified would
reasonably be likely to have a Material Adverse Effect on such subsidiary.

          4.6  FINANCIAL STATEMENTS .  The Company has delivered to Buyer copies
(which copies are complete and correct) of (I) the audited balance sheets and
related statements of income and cash flows of the Company and its subsidiaries

1997 (the "AUDITED FINANCIAL STATEMENTS") and (II) the unaudited balance sheet
and related statements of income and cash flows of the Company and its
subsidiaries on a consolidated basis for the nine months ended June 26, 1998
(the "UNAUDITED FINANCIAL STATEMENTS", together with the Audited Financial
Statements, the "FINANCIAL STATEMENTS").  The Financial Statements present
fairly in all material respects the financial condition and results of
operations of the Company and its subsidiaries on a consolidated basis as of the
dates and for the periods indicated.  The Audited Financial Statements have been
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently applied throughout the periods covered thereby.  The Unaudited
Financial Statements have been prepared in accordance with GAAP and on  a
consistent basis with the Audited Financial Statements, except as set forth in
Schedule 4.6.

          4.7  ABSENCE OF UNDISCLOSED LIABILITIES .  Except for liabilities
reflected or reserved against in the Audited Financial Statements for the fiscal
year ending September 30, 1997 and the Unaudited Financial Statements or
reflected in the schedules hereto, none of the Company or any of its
subsidiaries has any liabilities or obligations (absolute or accrued or
contingent, whether accrued or unaccrued and whether due or to become due) other
than liabilities and obligations incurred in the ordinary course of business
since June 26, 1998 or liabilities or obligations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company and its subsidiaries taken as a whole.

          4.8  REAL PROPERTY; ASSETS .  (a)  Schedule 4.8(a) lists all real
property owned by the Company or its subsidiaries (the "OWNED REAL PROPERTY") or

Schedule 4.8(a), the Company and its subsidiaries have good and marketable title
to the Owned Real Property listed on Schedule 4.8(a) and valid and subsisting
leasehold interests in the Leased Real Property listed on Schedule 4.8(a), in
each case, free and clear of all Liens, except for (I) Liens reflected in
Schedule 4.8(a), (II) Liens for taxes and other governmental charges and
assessments which are not yet due and payable or which are being contested in
good faith by appropriate proceedings if a reserve or other appropriate
provisions, if any, as shall be required by GAAP shall have been made therefor,
(III) Liens of carriers, warehousemen, mechanics and materialmen and other like
Liens arising in the ordinary course of


                                          13


business for sums that are not yet due and payable, (IV) easements, rights of
way, title imperfections and restrictions, zoning ordinances and other similar
encumbrances affecting the Real Property, in each case, which do not interfere
with the ordinary conduct of the business of the Company or its subsidiaries and
do not materially detract from the value of the property to which such
encumbrance relates, (V) statutory Liens in favor of lessors arising in
connection with any property leased to the Company or any of its subsidiaries
which do not interfere with the ordinary conduct of the business of the Company
or its subsidiaries and do not materially detract from the value of the property
to which such encumbrance relates and (VI) Liens reflected on the face of or in
the notes to the Financial Statements ("PERMITTED LIENS").  The Real Property
and Leased Personal Property is used and operated (I) in conformity with all
applicable leases, and (II) in conformity with all applicable contracts,
commitments, licenses and permits, to the extent that the failure so to conform
would not individually or in the aggregate, have a Material Adverse Effect on
the Company. 

          (b)  Except as set forth in Schedule 4.8(b), the Company and its
subsidiaries have legal and beneficial ownership of all of their respective
tangible personal property and assets included in the June 26, 1998 balance

business since the date of such balance sheet and listed on Schedule 4.8, which
Schedule shall not include inventory sold pursuant to contracts with customers,
in each case, free and clear of all Liens, except for Permitted Liens.  Except
as set forth on Schedule 4.8(b), the Company and its subsidiaries own or have
the right to use all of the tangible personal properties and assets necessary
for the conduct of their business as currently conducted.  Each such property or

good operating condition and repair (subject to normal wear and tear and any
improvements or replacements included within the Company's Capital Expenditure
Plan (as defined herein)), and is suitable for the purpose for which it is
currently used.

          (c)  EXCEPT AS OTHERWISE SPECIFICALLY SET FORTH IN THIS AGREEMENT, THE
PARTIES EXPRESSLY DISCLAIM ANY IMPLIED WARRANTY OR REPRESENTATION AS TO
CONDITION, MERCHANTABILITY OR SUITABILITY AS TO ANY OF THE ASSETS OF THE COMPANY

                                          16


          4.10.2  ERISA .  Each Plan has been maintained in compliance and
presently complies in all material respects with the requirements of all
applicable laws, including ERISA and the Internal Revenue Code of 1986, as
amended (the "CODE").  No Plan that is subject to section 302 of ERISA or
section 412 of the Code has incurred any "accumulated funding deficiency" within
the meaning of section 302 of ERISA or section 412 of the Code, whether or not
waived, and no material liability (other than for annual premiums) to the
Pension Benefit Guaranty Corporation has been incurred by the Company or any of
its subsidiaries with respect to any Plan.  Except as set forth on Schedule
4.10, as of the last day of the last plan year of each Plan that is an employee
pension plan as defined in Section 3(3) of ERISA and as of the Effective Time,
the "amount of unfunded benefit liabilities" as defined in Section 4001(a)(18)
of ERISA (but excluding from the definition of "current value" of "assets" of
such Plan, accrued but unpaid contributions) did not and will not exceed zero. 
None of the Company or any of its subsidiaries or any Plan has any present or
future obligation to make any payment to, or with respect to any present or
former employee of the Company or any of its subsidiaries pursuant to, any
retiree medical benefit plan.  There is no contract, agreement, plan or
arrangement covering any employee or former employee of the Company or any of
its subsidiaries that, individually or collectively, provides for the payment by
the Company of any amount (I) that is not deductible under Section 162(a)(1) of
the Code or (II) that is an "excess parachute payment" pursuant to Section 280G
of the Code.  None of the Company or any of its subsidiaries has withdrawn at
any time within the preceding six years from any multi-employer plan, as defined
in section 3(37) or 4001(a)(3) of ERISA (a "MULTI-EMPLOYER PLAN"), and incurred
any material withdrawal liability which remains unsatisfied.  If, as of the
Effective Time, the Company and each of its subsidiaries were to withdraw from
all multi-employer plans to which it (or any of them) has contributed or been
obligated to contribute, it (and they) would incur no material liabilities to
such plans under Title IV of ERISA.  None of the Company nor any of its
subsidiaries has engaged in a transaction with respect to any Plan that would
reasonably be expected to subject the Company or any of its subsidiaries to a
tax or penalty imposed by either section 4975 of the Code or section 502(i) of
ERISA.  Except as set forth on Schedule 4.10.2, there are no material pending
or, to the Company's knowledge, threatened claims by or on behalf of any of the
Plans or by any present and former employee or governmental authority involving
any such Plan (other than routine claims for benefits).  All contributions
required to have been made by the Company or any of its subsidiaries to any Plan
under the terms of any such plan or pursuant to any applicable Collective
Bargaining Agreement (as defined in Section 4.10.4 below) or applicable law
(including, without limitation, ERISA and the Code) have been timely made.  With
respect to each Plan, the Company has made available to Buyer copies of the plan
documents and summary plan descriptions, the most recent determination letter
received from the Internal Revenue Service, the most recent Form 5500 Annual
Report, and related trust agreements and insurance contracts or other funding
arrangements which implement each such Plan.  None of the Company, any of its

corporate power and authority to carry on its business as it is now being
conducted and is duly qualified and licensed to do business, and is in good
standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification
necessary, except where the failure to be so qualified would not, individually

hereunder.  The execution and delivery of this Merger Agreement and the

their respective properties or assets are bound, or (III) the creation or
imposition of any Lien, except, in the case of clauses (ii) and (iii) of this
Section 5.2, for such breaches, violations or defaults and such Liens which

the transactions contemplated hereby have been carried out without the

each party will refrain


                                          29

reasonable best efforts to take any action necessary to prevent, any of the
representations and warranties made by it in this Merger Agreement not to be
true and correct in all material respects at and as of the Closing Date with the
same force and effect as then made (except with respect to representation and
warranties which are made as of a specific date), subject only to exceptions
permitted or expressly contemplated by this Merger Agreement.  The Company
further covenants and agrees, with respect to any threatened or pending
judgment, order, injunction, decree or decision of any governmental authority

prevent the entry or promulgation thereof and to defend and cooperate with each
other in the defending of any legal proceedings, whether judicial or
administrative and whether brought derivatively or on behalf of third parties
challenging the transaction contemplated hereby as the case may be, it being
understood that such efforts shall not include any requirement of the Company to
expend material sums of money or grant any material financial or other
accommodation.

set forth in the Financing Letters.  The Company agrees to provide, and will

purposes of conducting any environmental audit or assessment without the prior
written consent of the Company.  The Company further agrees to furnish Buyer

Certificate of Incorporation or By-laws relating to the exculpation or
indemnification of former officers and directors (unless required by law) in a

Closing Date shall continue to be entitled to such exculpation and
indemnification to the fullest extent permitted under applicable law.

          6.7  CONTACT WITH CUSTOMERS AND SUPPLIERS .  Buyer and its
representatives shall contact and communicate with the employees, customers,
suppliers and licensors of the Company in connection with the transactions

business of, or of any Equity Securities of, the Company or any subsidiary, or
any business combination or any recapitalization, dissolution or similar
transaction involving the Company (each such transaction being referred to
