Item 5.   Other Events
          ------------

         Amended and Restated Agreement and Plan of Merger with Greenwich Air
Services, Inc.

         On March 9, 1997, UNC Incorporated (the "Registrant"), Greenwich Air
Services, Inc. ("Greenwich"), a Delaware corporation, and Condor Acquisition
Corp., a Delaware corporation and wholly-owned subsidiary of Greenwich
("Condor"), entered into an Amended and Restated Agreement and Plan of Merger
(the "Amended Merger Agreement") modifying and restating the terms of the
Agreement and Plan of Reorganization previously entered into by the parties on
February 13, 1997 (the "Original Merger Agreement") pursuant to which the
Registrant will merge with Condor (the "UNC-Greenwich Merger"), thereby becoming
a wholly-owned subsidiary of Greenwich.

         The Amended Merger Agreement modifies, among other things, the
consideration to be received by holders of the Common Stock, $0.20 par value per
share of the Registrant (the "UNC Common Stock"), by virtue of the UNC-Greenwich
Merger. Pursuant to the Amended Merger Agreement, holders of UNC Common Stock
shall be entitled to receive at the Effective Time (as defined in the Amended
Merger Agreement) $15.00 in cash for each share of UNC Common Stock then
currently issued and outstanding.

         Concurrently with the execution and delivery of the Amended Merger
Agreement, Greenwich, General Electric Company, a New York corporation ("GE"),
and GB Merger Corp., a wholly-owned subsidiary of GE, entered into an Agreement
and Plan of Merger pursuant to which those parties have agreed that Greenwich
will merge with GB Merger Corp. (the "GE-Greenwich Merger"), thereby becoming a
wholly-owned subsidiary of GE.

         Consummation of the UNC-Greenwich Merger pursuant to the Amended Merger
Agreement is subject to a number of conditions, including approval by the
stockholders of the Registrant entitled to vote thereon, certain regulatory
approvals, and satisfaction or waiver of all conditions to the GE-Greenwich
Merger. The GE-Greenwich Merger is, in turn, subject to a number of conditions,
including approval by the Greenwich stockholders entitled to vote thereon and
certain regulatory approvals. If the GE-Greenwich Merger is terminated for any
reason, the Amended Merger Agreement provides, in effect, that the terms of the
Original Merger Agreement are revived, with certain modifications as specified
in section 6.17 of the Amended Merger Agreement. The terms and conditions of the
Original Merger Agreement were previously disclosed in the Registrant's Current
Report on Form 8-K dated February 13, 1997, which report is incorporated herein
by reference.

         The terms and conditions of the Amended Merger Agreement were
determined as a result of arm's length negotiations among the Registrant, 
Greenwich, and GE.

          Section 2.2.  Conversion of Securities.   At the Effective Time, by
                        ------------------------                             
virtue of the Merger and without any action on the part of Merger Sub, UNC, or
any holder of the securities of either:

                  (a)   Common Shares.  Each share of UNC Common Stock issued 
                        -------------
and outstanding immediately before the Effective Time (other than Treasury
Shares to be canceled pursuant to Section 2.2(c) and any Dissenting Shares (as
hereinafter defined)) shall be canceled and shall be converted automatically
into the right to receive an amount equal to $15.00 in cash (the "Merger
Consideration") payable, without interest, to the holder of such share upon
surrender, in the manner provided in Section 2.3, of the certificate that
formerly evidenced such share.

                  (b)   Preferred Shares. Each share of UNC Series B Preferred
                        ----------------
Stock issued and outstanding immediately before the Effective Time shall be
canceled and shall be converted automatically into the right to receive an
amount equal to $15.00 in cash multiplied by the number of shares (including any
fraction of a share) of UNC Common Stock into which such share of UNC Series B

                  (c)   Treasury Shares.  All issued and outstanding shares of
                        ---------------
UNC Stock which are held by UNC, any Subsidiary of UNC, Greenwich, Merger Sub or
any other Subsidiary of Greenwich ("Treasury Shares") shall be canceled and no
consideration shall be issued in respect thereof.

                  (d)   Dissenting Shares.  Notwithstanding the foregoing 
                        -----------------
provisions or any other provision of this Agreement to the contrary, shares of
UNC Stock held by any holder who shall have taken the necessary steps under the
DGCL to dissent and demand payment and is otherwise entitled to such payment
under the DGCL, if the DGCL provides for such payment in connection with the
Merger ("Dissenting Shares"), shall not be converted into the right to receive
Merger Consideration at or after the Effective Time unless and until the holder
of such Dissenting Shares withdraws his or her demand for such appraisal with
the consent of UNC, if required by the DGCL, or becomes ineligible for such
appraisal. If a holder of Dissenting Shares shall withdraw his or her demand for
such appraisal with the consent of UNC, if required by the DGCL, or shall become
ineligible for such appraisal (through failure to perfect or otherwise), then,
as of the Effective Time or the occurrence of such event, whichever last occurs,
such holder's Dissenting Shares shall automatically be converted into and
represent the right to receive the Merger Consideration as provided above. UNC
shall give Greenwich (i) prompt notice of any written demands for appraisal,
withdrawals of demands for appraisal and any other instruments served pursuant
to Section 262 of the DGCL received by UNC, and (ii) the opportunity to direct
all negotiations and proceedings with respect to demands for appraisal under
Section 262 of the DGCL. UNC will not voluntarily make any payment with respect
to any demands for appraisal and will not, except with the prior written consent
of Greenwich, settle or offer to settle any such demands. Each holder of
Dissenting Shares shall have only such rights and remedies as are granted to
such a holder under Section 262 of the DGCL.

                  (e)   Shares of Merger Sub.  Each share of Common Stock, par
                        --------------------
value $.01 per share, of Merger Sub issued and outstanding immediately before
the Effective Time shall be converted into and exchanged for one validly issued,
fully paid and nonassessable share of Common Stock, par value $.01 per share, of
the Surviving Corporation.
<PAGE>
 
          Section 2.3.  Surrender of Certificates; Stock Transfer Books.  (a)
                        -----------------------------------------------      
Before the Effective Time, Merger Sub shall designate a bank or trust company to

connection with the Merger. From and after the Effective Time Greenwich shall
cause funds to be deposited with the Paying Agent sufficient to pay the amounts
to which the holders of shares of UNC Stock shall become entitled pursuant to
Section 2.2. Such funds shall be invested by the Paying Agent as directed by the
Surviving Corporation, provided that such investments shall be in obligations of
or guaranteed by the United States of America or of any agency thereof and
backed by the full faith and credit of the United States of America, in
commercial paper obligations rated A-1 or P-1 or better by Moody's Investors
Services, Inc. or Standard & Poor's Corporation, respectively, or in deposit
accounts, certificates of deposit or banker's acceptances of, repurchase or
reverse repurchase agreements with, or Eurodollar time deposits purchased from,
commercial banks with capital, surplus and undivided profits aggregating in
excess of $1 billion (based on the most recent financial statements of such bank
which are then publicly available to the SEC or otherwise).

                  (b)   Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each person who was, at the Effective
Time, a holder of record of shares of UNC Stock entitled to receive the Merger
Consideration pursuant to Section 2.2 a form of letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
certificates evidencing such shares of UNC Stock ("UNC Certificates") shall
pass, only upon proper delivery of the UNC Certificates to the Paying Agent) and
instructions for use in effecting the surrender of the UNC Certificates pursuant
to such letter of transmittal. Upon surrender to the Paying Agent of a UNC
Certificate, together with such letter of transmittal, duly completed and
validly executed in accordance with the instructions thereto, and such other
documents as may be required pursuant to such instructions, the holder of such
UNC Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each share of UNC Stock formerly evidenced by such UNC
Certificate, and such UNC Certificate shall then be cancelled. No interest shall
accrue or benefit the holder of such UNC Certificate.

                  (c)   At any time after six (6) months from the Effective
Time, the Surviving Corporation shall be entitled to require the Paying Agent to
deliver to it any funds which had been made available to the Paying Agent and
not disbursed to holders of shares of UNC Stock (including, without limitation,
all interest and other income received by the Paying Agent in respect of all
funds made available to it), and thereafter such holders shall be entitled to
look to the Surviving Corporation (subject to abandoned property, escheat and
other similar laws) only as general creditors thereof with respect to any Merger
Consideration that may be payable upon due surrender of the UNC Certificates
held by them.

                  (d)   After the Effective Time, there shall be no transfers on
the stock transfer books of UNC of any shares of UNC Stock that were outstanding
immediately before the Effective Time. If, after the Effective Time, UNC
Certificates are presented to Greenwich or UNC for transfer, they shall be
cancelled and exchanged for payment of the applicable amount of Merger
Consideration as provided in Section 2.2, in accordance with the procedures set
forth in this Section 2.3.

                  (e)   Notwithstanding the foregoing, neither Greenwich nor UNC
shall be liable to any holder of shares of UNC Common Stock or UNC Series B
Preferred Stock for any payment of the per share cash portion of the Merger
Consideration delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

          Section 2.4.  Transfer Taxes.  If cash is to be paid to a person other
                        --------------                                          
than the holder in whose name the certificate representing shares of UNC Stock
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the certificate so surrendered shall be properly endorsed or
otherwise in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other taxes required by
reason of the payment of such cash to a person other than the registered holder
of the certificate surrendered or shall establish to the satisfaction of the
Paying Agent that such tax has been paid or is not applicable.

          2.5. Stock Options.  All unexercised UNC Stock Options which shall be
               -------------                                                   
outstanding as at the Effective Time shall be canceled and converted into the
right to receive, in full consideration of such securities, a cash payment equal
to the product of: (A) the aggregate number of shares of UNC Common Stock
       -------

required to be delivered to the stockholders of UNC under the Exchange Act, any
event occurs as a result of which either the UNC Proxy Statement as then amended

state any material fact necessary to make the statements contained therein, in
light of the circumstances under which they were made, not misleading, or if it
shall be necessary to amend the UNC Proxy Statement or to supplement such Proxy
Statement in order to comply with the Exchange Act or the rules thereunder, UNC
shall prepare and file with the SEC an amendment or supplement that will correct
such statement or omission or effect such compliance, and Greenwich shall
cooperate with UNC in preparing such amendment or supplement.

such recommendation in any respect materially adverse to Greenwich; or

                         (iv)   if there shall occur a breach by UNC of any
representation or warranty set forth in this Agreement, which breach has a UNC
Material Adverse Effect and is within the actual knowledge of any Person listed
in Schedule 1.46, or UNC shall breach any covenant or agreement contained in

group makes a bona fide proposal with respect to the acquisition of all or
substantially all of UNC's outstanding capital stock or assets, that the Board
of Directors of UNC believes in good faith after consultation with its financial
advisors, is more favorable, from a financial point of view, to the stockholders
of UNC than the proposal set forth in this Agreement (a "Superior Proposal");
provided that Greenwich does not (in its sole option) elect to make, within ten
- --------
Business Days after receiving notice of such Superior Proposal, an offer that
the Board of Directors of UNC believes, in good faith after consultation with
its financial advisors, is at least as favorable, from a financial point of
view, to the UNC stockholders as such Superior Proposal; or

                         ---------------------
of this Agreement and the Merger by either Greenwich or UNC, this Agreement
shall become void and there shall be no liability hereunder on the part of
Greenwich or UNC or their respective officers or directors except, in each case,
as otherwise provided in Sections 11.3 and 12.1 hereof, which Sections shall
survive any such termination and continue in effect thereafter.

          Section 11.3   Termination Payments and Expenses.
                         --------------------------------- 

                  (a)    If this Agreement is terminated:

                         (i)    by Greenwich, pursuant to clauses (ii), (iii) or
                                (iv) of Section 11.1(d); or

                         (ii)   by UNC, pursuant to Section 11.1(e);

then UNC shall promptly pay to Greenwich the sum of $20 million.

                  (b)    Each party hereto acknowledges that the agreements
contained in this Section 11.3 are an integral part of the transactions
contemplated by this Agreement and that, without these agreements, none of the
parties hereto would enter into this Agreement. Accordingly, if any party hereto
fails to pay any amounts pursuant to this Section 11.3, and, in order to obtain
such payment, legal action is commenced which results in a judgment therefor,
the liable party will pay the plaintiff's reasonable costs (including reasonable
<PAGE>
 
attorneys' fees) in connection with such suit, together with interest computed
on any amounts determined pursuant to this Section 11.3 (computed from the date
when such amounts were due and payable pursuant to this Section 11.3) and such
costs (computed from the date or dates incurred) at the prime rate of interest
announced from time to time by Citibank, N.A. The parties' obligations pursuant
to this Section 11.3 will survive any termination of this Agreement.

                  (c)    In the event that Greenwich shall terminate this
Agreement by reason of any of the events specified in Section 11.1, none of the
Greenwich Companies nor their Affiliates shall have any liability or obligation
to any of the UNC Companies or their Affiliates under this Agreement, or
otherwise.

                  (d)    The remedies of Greenwich set forth in this 
Section 11.3 constitute full and complete liquidated damages and represent the
sole and exclusive remedies at law of such party as a result of the termination
of this Agreement pursuant to Section 11.3.

                  (e)    Nothing herein contained shall prevent a party
otherwise entitled to seek specific performance of this Agreement from applying
to and obtaining from a court of competent jurisdiction such equitable relief as
such court may deem proper in the circumstances.

                  (f)    Except as provided in this Section 11.3, all costs and
expenses incurred in connection with this Agreement shall be paid in accordance
with Section 12.1.

- ---                                                                   -------   

          WHEREAS, the parties hereto desire to cause the Company, upon the

and into Merger Sub (the "Merger");
                          ------   

          WHEREAS, the Board of Directors of the Company has (i) determined that
the Merger is fair to the holders of shares of Company Common Stock (as such
term is defined in Section 2.01) and is in the best interests of such
stockholders and (ii) approved this Agreement and the transactions contemplated

Agreement;

          WHEREAS, the Board of Directors of Parent has determined that the

          WHEREAS, for federal income tax purposes, it is intended that the

                                         ---------------------------            
to which, among other things, such stockholders have agreed, subject to the
terms and conditions contained therein, to vote all shares of Class A Common
Stock then owned by such stockholders to approve and adopt this Agreement, and

upon the terms and subject to the conditions set forth therein.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained and intending to be legally bound

right to receive the Merger Consideration.

          (b) Cash Election; Cash Election Adjustments.  Each holder of record
              ----------------------------------------                        
of Company Common Stock as of the record date for the Stockholders' Meeting (as

Common Stock held by such holder, to elect to receive the Cash Consideration (a
"Cash Election"); provided, however, that if the aggregate number of shares of
 -------------    --------  -------

                                  --------------------                     
Shares shall be converted into the right to receive Parent Common Stock and cash
in the following manner:

          each Cash Election Share shall be converted into the right to receive
          (i) an amount in cash, without interest, equal to the product of (x)
          the Cash Consideration and (y) a fraction (the "Cash Fraction"), the
                                                          -------------       
          numerator of which shall be the Cash Election Number and the
          denominator of which shall be the total number of Cash Election
          Shares, and (ii) such number of shares of (rounded to the nearest one
          thousandth of a share) Parent Common Stock equal to the product of (x)
          the Cash Consideration divided by the Average Parent Share Price and
          (y) a fraction equal to one minus the Cash Fraction.

          (c) Adjustments Relating to Tax Opinions.  If either (i) the tax
              ------------------------------------                        
opinion of counsel to Parent referred to in Section 7.02(c) cannot be rendered
(as reasonably determined by counsel to Parent and concurred in by Greenberg,
Traurig, Hoffman, Rosen, Lipoff & Quentel ("Greenberg, Traurig")) or (ii) the
                                            ------------------               
tax opinion of Greenberg, Traurig referred to in Section 7.03(b) cannot be
rendered (as reasonably determined by Greenberg, Traurig and concurred in by
counsel to Parent), in either case as a result of the Merger potentially failing
to satisfy continuity of interest requirements under applicable federal income
tax principles relating to reorganizations under Section 368(a) of the Code,
then Parent shall reduce to the minimum extent necessary to enable the relevant
tax opinion or opinions, as the case may be, to be rendered, the Cash Election
Number.

                                       4

          (d) Exercise of Election.  All Cash Elections shall be made on a form
              --------------------                                             
designed for that purpose and mutually acceptable to the Company and Parent (a
                                                                              
"Form of Election") and mailed to holders of record of shares of Company Common
- -----------------                                                              
Stock as of the record date for the Stockholders' Meeting or such other date as
Parent and the Company shall mutually agree (the "Election Form Record Date").
                                                  -------------------------    
Parent and the Company shall make available one or more Forms of Election as may
be reasonably requested by all persons who become holders (or beneficial owners)
of Company Common Stock between the Election Form Record Date and the close of
business on the day prior to the Election Deadline (as defined below).
Elections shall be made by holders of Company Common Stock by mailing to the
Exchange Agent (as defined in Section 2.04) a Form of Election.  To be
effective, a Form of Election must be properly completed, signed and submitted
to the Exchange Agent and accompanied by the Certificates (as defined in Section
2.04(b)) representing the shares of Company Common Stock as to which the
election is being made (or an appropriate guarantee of delivery by an
appropriate trust company in the United States or a member of a registered
national securities exchange or the National Association of Securities Dealers,
Inc.).  Parent will have the discretion, which it may delegate in whole or in
part to the Exchange Agent, to reasonably determine whether Forms of Election
have been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Forms of Election.  The decision of Parent (or the
Exchange Agent) in such matters shall be conclusive and binding.  The Exchange
Agent shall make a good faith effort to notify any person of any defect not
waived by Parent in a Form of Election submitted to the Exchange Agent. The
Exchange Agent shall also make all computations contemplated by this Section
2.03 and all such computations shall, absent manifest error, be conclusive and
binding on the holders of Company Common Stock.

          (e) Election Deadline.  A Form of Election must be received by the
              -----------------                                             
Exchange Agent (as defined below) by the close of business on the last business
day prior to the Closing Date (the "Election Deadline") in order to be
                                    -----------------                 
effective.  Any holder of Company Common Stock who has made an election by
submitting a Form of Election to the Exchange Agent may at any time prior to the

Effective Time, Parent shall cause the Exchange Agent to mail to each holder of
a certificate or certificates (to the extent such certificates have not already
been submitted to the Exchange Agent with Forms of Election) which immediately
prior to the Effective Time represented outstanding shares of Company Common

customary form and shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent) and (ii) instructions for use in effecting

          (c) Exchange of Certificates.  Upon surrender to the Exchange Agent of
              ------------------------                                          
a Certificate for cancellation, together with such letter of transmittal, duly
executed and completed in accordance with the instructions thereto, and such
other documents as may be reasonably required pursuant to such instructions, the
holder of such Certificate shall be entitled to receive in exchange therefor (A)
a certificate representing that number of whole shares of Parent Common Stock,
if any, to which such holder is entitled pursuant to this Article II and (B) a
check in the amount equal to the cash, if any, to which such holder is entitled
pursuant to the provisions of this Article II (including any cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled

In the event of a transfer of ownership of shares of Company Common Stock which
is not registered in the transfer records of the Company, the applicable Merger
Consideration and Additional Payments, if any, may be issued to a transferee if
the Certificate representing such shares of Company Common Stock is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid.  Until surrendered as contemplated by this Section 2.04, each Certificate
shall be deemed at all times after the Effective Time to represent only the
right to receive upon such surrender the applicable Merger Consideration with
respect to the shares of Company Common Stock formerly represented thereby and
Additional Payments, if any.

          (d) Distributions with Respect to Unsurrendered Certificates.  No
              --------------------------------------------------------     
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock the holder thereof is entitled to receive upon
surrender thereof, and no cash payment in lieu of any fractional shares shall be
paid to any such holder pursuant to Section 2.04(f), until the holder of such
Certificate shall surrender such Certificate.  Subject to the effect of escheat,
tax or other applicable Laws, following surrender of any such Certificate, there
shall be paid to the holder of the certificates representing whole shares of
Parent Common Stock issued in exchange therefor, without interest, (i) promptly,
the amount of any cash payable with respect to a fractional share of Parent
Common Stock to which such holder is entitled pursuant to Section 2.04(f) and
the amount of dividends or other distributions with a record date after the
Effective Time and theretofore paid with respect to such whole shares of Parent
Common Stock, and (ii) at the appropriate payment date, the amount of dividends
or other distributions, with a record date after the Effective Time but prior to
surrender and a payment date occurring after surrender, payable with respect to
such whole shares of Parent Common Stock.  After the Effective Time, each
outstanding Certificate which theretofore represented shares of Company Common
Stock shall, until surrendered for exchange in accordance with this Section
2.04, be deemed for all purposes to evidence ownership of the number of shares
of Parent Common Stock into which the shares of Company Common Stock (which,
prior to the Effective Time, were represented thereby) shall have been so
converted.

          (e) No Further Rights in Company Common Stock.  All shares of Parent
              -----------------------------------------                       
Common Stock issued or cash paid upon conversion of the shares of Company Common
Stock in accordance with the terms hereof (including any cash paid pursuant to
Section 2.04(d) or (f)) shall be deemed to have been issued in full satisfaction
of all rights pertaining to such shares of Company Common Stock.

          (f) No Fractional Shares.  No certificates or scrip representing
              --------------------                                        
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates, and such fractional share interests will not entitle
the owner thereof to vote or to any other rights of a stockholder of Parent.
Each holder of a fractional share interest shall be paid an amount in cash equal
to the product obtained by multiplying (i) such fractional share interest to
which such holder (after taking into account all fractional share interests then
held by such holder) would otherwise be entitled by (ii) the Average Parent
Share Price.  As promptly as practicable after the determination of the amount
of cash, if any, to be paid to holders of fractional share interests, the
Exchange Agent shall so notify Parent, and Parent shall deposit such amount with
the Exchange Agent and shall cause the Exchange Agent to forward payments to
such holders of fractional share interests subject to and in accordance with the
terms of Sections 2.04(b), (c) and (d).

          (g) Termination of Exchange Fund.  Any portion of the Exchange Fund
              ----------------------------                                   
(including any shares of Parent Common Stock) which remains undistributed to the
holders of Company Common Stock for six months after the Effective Time shall be
delivered to Parent, upon demand, and any holders of Company Common Stock who
have not theretofore complied with this Article II shall thereafter look only to
Parent for the applicable Merger Consideration and any Additional Payments to
which they are entitled.  Any portion of the Exchange Fund remaining unclaimed
by holders of shares of Company Common Stock as of a date which is immediately
prior to such time as such amounts would otherwise escheat to or become property
of any government entity shall, to the extent permitted by applicable Law,
become the property of Parent free and clear of any claims or interest of any
person previously entitled thereto.

          (h) No Liability.  None of the Exchange Agent, Parent or the Surviving
              ------------                                                      
Corporation shall be liable to any holder of Certificates for any shares of
Parent Common Stock (or dividends or distributions with respect thereto), or
cash delivered to a public official pursuant to any abandoned property, escheat
or similar law.

              ------------------                                               
shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of Certificates such amounts as
it is required to deduct and withhold with respect to the making of such payment
under the Code, or any provision of state, local or foreign tax law.  To the
extent that amounts are so withheld by the Surviving Corporation or Parent, as
the case may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Certificates in respect of
which such deduction and withholding was made by the Surviving Corporation or
Parent, as the case may be.

          (j) Lost Certificates.  If any Certificate shall have been lost,
              -----------------                                           
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the applicable Merger Consideration and Additional Payments, if any.

          (k) Further Assurances.  If, at any time after the Effective Time, the
              ------------------                                                
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of the Merger Sub or the Company acquired or to
be acquired by the Surviving Corporation as a result of, or in connection with,
the Merger or otherwise to carry out this Agreement, the officers of the
Surviving Corporation shall be authorized to execute and deliver, in the name
and on behalf of each of the Merger Sub and the Company or otherwise, all such
deeds, bills of sale, assignments and assurances and to take and do, in such
names and on such behalves or otherwise, all such other actions and things as

acceleration or cancellation of, or result in the creation of a lien or other
encumbrance on any property or asset of the Company or any Subsidiary pursuant

          SECTION 3.06.  Compliance with Laws; Permits.  (a)  Neither the
                         -----------------------------

property or asset of the Company or any Subsidiary is bound or affected, or (ii)

defaults or violations that do not, individually or in the aggregate, have a
Company Material Adverse Effect.

          (b) Except where non-compliance would not have a Company Material
Adverse Effect, the Company and the Subsidiaries have complied with all
applicable federal procurement laws and regulations including, without
limitation, the Truth in Negotiations Act, the Foreign Corrupt Practices Act,
the Office of Federal Procurement Policy Act Amendments of 1988 ("Procurement
Integrity" Amendments), the Cost Principles and Cost Accounting Standards, and
the Federal Acquisition Regulations and all supplements thereto, in connection
with the Government Contracts (as defined below), and to the Company's
Knowledge, no person has made any allegation that the Company or any Subsidiary

          (c) Each of the Company and the Subsidiaries is in possession of all
franchises, grants, authorizations, licenses, permits, easements, variances,
exceptions, consents, certificates, approvals and orders from all federal,
state, local and foreign authorities and agencies, including without limitation,
the Federal Aviation Administration, necessary for the Company or any of its

                                                  ---------------          
suspension or cancellation of any of the Company Permits is pending or, to the
Company's Knowledge, threatened, except where the failure to have, or the
suspension or cancellation of, any of the Company Permits, individually or in

          SECTION 3.07.  SEC Filings; Financial Statements.
                         -------------------------------- 

          (a) The Company has filed all forms, reports and documents required to
be filed by it with the Securities and Exchange Commission (the "SEC") since
                                                                 ---        
September 30, 1993 and has made available to the Parent all registration
statements filed by the Company with the SEC, including all exhibits filed in
connection therewith (on all forms applicable to the registration of securities)
since September 30, 1993 and prior to the date of this Agreement (collectively,
the "Company SEC Reports"), and has heretofore made available to Parent complete
     -------------------                                                        
(i.e., unredacted) copies of each exhibit (which is in effect as of the date
 ----                                                                       
hereof) to the Company SEC Reports filed with the SEC.  The Company SEC Reports
(i) were prepared in all material respects in accordance with the requirements
of the Securities Act or the Exchange Act, as the case may be, and the rules and
regulations thereunder and (ii) did not at the time they were filed contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements made therein, in
the light of the circumstances under which they were made, not misleading.

          (b) Except as disclosed in the Company SEC Reports, no Subsidiary is
required to file any form, report or other document with the SEC.

          (c) Each of the consolidated financial statements (including, in each
case, any notes and schedules thereto) contained in the Company SEC Reports
complied as to form with the applicable accounting requirements and rules and
regulations of the SEC and was prepared in accordance with United States
generally
<PAGE>
 
                                      11

accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as may be indicated in the notes thereto), and each
fairly presented the consolidated financial position, results of operations and
cash flows of the Company and the consolidated Subsidiaries as at the respective
dates thereof and for the respective periods indicated therein in accordance
with United States generally accepted accounting principles (subject, in the
case of unaudited statements, to normal and recurring year-end adjustments which
were not and are not expected, individually or in the aggregate, to have a
Company Material Adverse Effect).

          (d) Except as and to the extent set forth on the consolidated balance
sheet of the Company and the consolidated Subsidiaries as of September 30, 1996,
including the notes thereto (the "Company 1996 Balance Sheet"), neither the
                                  --------------------------               
Company nor any Subsidiary has any liability or obligation of any nature
(whether accrued, absolute, contingent or otherwise) that would be required to
be reflected on a balance sheet, or in the notes thereto, prepared in accordance
with United States generally accepted accounting principles, except for
liabilities and obligations (i) disclosed in any Company SEC Report filed since
September 30, 1996 and prior to the date of this Agreement, (ii) incurred since
September 30, 1996 in the ordinary course of business which, individually or in
the aggregate, do not have a Company Material Adverse Effect, or (iii) incurred
pursuant to this Agreement.

          (e) The Company has heretofore furnished to Parent complete and
correct copies of all material amendments and modifications that have not been
filed by the Company with the SEC to all agreements, documents and other
instruments that previously had been filed by the Company with the SEC and are
currently in effect.

          SECTION 3.08.  Absence of Certain Changes or Events.  Since September
                         ------------------------------------                  
30, 1996, except as contemplated by this Agreement, disclosed in Section 3.08 of
the Company Disclosure Schedule, or disclosed in any Company SEC Report filed
since September 30, 1996, the Company and the Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, since September 30, 1996, there has not been (a) any event or
events having, individually or in the aggregate, a Company Material Adverse
Effect, (b) any change by the Company in its accounting methods, principles or
practices, (c) any revaluation by the Company of any material asset (including,
without limitation, any writing down or writing up of the value of inventory,
writing off of notes or accounts receivable or reversing of any accruals or
reserves), other than in the ordinary course of business consistent with past
practice, (d) any entry by the Company or any Subsidiary into any commitment or
transaction material to the Company and the Subsidiaries taken as a whole,
except in the ordinary course of business and consistent in all material
respects with past practice, (e) other than regular dividends, of which $.01 per
share of Company Common Stock was paid in February 1996 and $.012 per share of
Company Common Stock was paid in January 1997, any declaration, setting aside or
payment of any dividend or distribution in respect of any capital stock of the
Company or any redemption, purchase or other acquisition of any of its
securities, or (f) other than pursuant to the contracts referred to in Section
3.10 or as expressly provided for in this Agreement, any increase in or
establishment of any bonus, insurance, severance, deferred compensation,
pension, retirement, profit sharing, stock option (including, without
limitation, the granting of stock options, stock appreciation rights,
performance awards, or restricted stock awards), stock purchase or other
employee benefit plan, or any other increase in the compensation payable or to
become payable to any officers or key employees of the Company or any
Subsidiary, except in the ordinary course of business consistent in all material
respects with past practice.  The results of operations for the most recently
completed fiscal quarter are not materially lower than the results of operations
for the immediately preceding fiscal quarter, and there is no reason to believe
that the results of operations for the current fiscal quarter will be materially
lower than the results of operations for the Company's most recently completed
fiscal quarter.

          SECTION 3.09.  Absence of Litigation.
                         --------------------- 

          (a) Except as disclosed in the Company SEC Reports or in Section 3.09
of the Company Disclosure Schedule, there is no claim, action, proceeding or
investigation pending or, to the Company's
<PAGE>
 
                                      12

Knowledge, threatened against the Company or any Subsidiary, or any property or
asset of the Company or any Subsidiary, before any court, arbitrator or
Governmental Authority, which, individually or when aggregated with other
claims, actions, proceedings or investigations or product liability claims,
actions, proceedings or investigations which are reasonably likely to result
from facts and circumstances that have given rise to such a claim, action,
proceeding or investigation, would have a Company Material Adverse Effect. As of
the date hereof, neither the Company nor any Subsidiary nor any property or
asset of the Company or any Subsidiary is subject to any order, writ, judgment,
injunction, decree, determination or award having, individually or in the
aggregate, a Company Material Adverse Effect.

          (b) Neither the Company nor any Subsidiary has received notice from
any source that the Company or any Subsidiary may be liable with respect to
product liability or worker's compensation claims, except for such claims that,
if determined adversely to the Company and the Subsidiaries, would not,
individually or in the aggregate, have a Company Material Adverse Effect.

          SECTION 3.10.  Employee Benefit; ERISA.
                         ----------------------- 

          (a)  Section 3.10(a) of the Company Disclosure Schedule contains a
list of all "employee pension benefit plans" (as defined in Section 3(2) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
                                                              -----   
(sometimes referred to herein as "Company Pension Plans"), "employee welfare
                                  ---------------------                     
benefit plans" (as defined in Section 3(1) of ERISA) (sometimes referred to
herein as "Welfare Plans"), and each other plan, arrangement or policy (written
           -------------                                                       
or oral) relating to stock options, stock purchases, compensation, deferred
compensation, severance, fringe benefits or other employee benefits, in each
case maintained, or contributed to, by the Company or any of the Subsidiaries or
any other person or entity that, together with the Company is treated as a
single employer under Section 414(b), (c), (m) or (o) of the Code (each,
together with the Company, a "Commonly Controlled Entity"), for the benefit of
                              --------------------------                      
any current or former employees, officers, agents or directors of the Company or
any of its subsidiaries (all of the foregoing being herein called "Company
                                                                   -------
Benefit Plans").  The Company has made available to Parent true and complete
- -------------                                                               
copies of (w) each Company Benefit Plan (or, in the case of any unwritten
Company Benefit Plans, descriptions thereof), (x) the most recent annual report
on Form 5500 filed with the Internal Revenue Service with respect to each
Company Benefit Plan (if any such report was required), (y) the most recent
summary plan description (or similar document) for each Company Benefit Plan for
which a summary plan description is required or was otherwise provided to plan
participants or beneficiaries and (z) each trust agreement and group annuity
contract relating to any Company Benefit Plan.

          (b) Except as disclosed in Section 3.10(b) of the Company Disclosure
Schedule or where non-disclosure would not have a Company Material Adverse
Effect, all Company Pension Plans and related trusts that are intended to be
tax-qualified plans have been, since the effective date of the Tax Reform Act of
1986, the subject of determination letters from the Internal Revenue Service to
the effect that such Company Pension Plans and related trusts are qualified and
exempt from federal income taxes under Sections 401(a) and 501(a), respectively,
of the Code, and no such determination letter has been revoked nor, to the
Knowledge of the Company, has revocation been threatened; no event has occurred
and no circumstances exist that would adversely affect the tax qualification of
such Company Pension Plan nor has any such Company Pension Plan been amended
since the date of its most recent determination letter or application therefor
in any respect that would adversely affect its qualification or materially
increase its costs or require security under Section 302 of ERISA.

          (c) Except as would not, individually or in the aggregate, have a
Company Material Adverse Effect: (i) each Company Benefit Plan has been
administered in accordance with its terms; (ii) the Company Benefit Plans are,
and have been administered, in compliance with the applicable provisions of
ERISA, the Code, and all other applicable laws; (iii) there are no
investigations by any governmental agency, termination proceedings or other
claims (except claims for benefits payable in the normal operation of the
Company Benefit Plans), suits or proceedings against or involving any Company
Benefit Plan or asserting any rights to or claims for benefits under
<PAGE>
 
                                      13

any Company Benefit Plan that could give rise to any liability, and there are
not any facts that would reasonably be expected to give rise to any liability in
the event of any such investigation, claim, suit or proceeding.

          (d) No Commonly Controlled Entity is required to contribute to any
"multiemployer plan" as defined in Section 4001(a)(3) of ERISA or, except as set
forth in Section 3.10(d) of the Company Disclosure Schedule, has withdrawn from
any such multiemployer plan where such withdrawal has resulted or would result
in any material  "withdrawal liability" (within the meaning of Section 4201 of
ERISA) that has not been fully paid.  Except as set forth in Section 3.10(d) of
the Company Disclosure Schedule, no Commonly Controlled Entity would incur any
material withdrawal liability if it were to withdraw from a multiemployer plan
with respect to which it currently has a contribution obligation.  No Commonly
Controlled Entity, nor any officer of any Commonly Controlled Entity, nor any of
the Company Benefit Plans which are subject to ERISA, including the Company
Pension Plans, any trusts created thereunder or any trustee or administrator
thereof, has engaged in a "prohibited transaction" (as such term is defined in
Section 406 of ERISA or Section 4975 of the Code) or any other breach of
fiduciary responsibility that could subject any Commonly Controlled Entity or
any officer of any Commonly Controlled Entity to any tax or penalty on
prohibited transactions imposed by such Section 4975 or to any material
liability under Section 502(i) or (l) of ERISA.  Neither any of such Company
Benefit Plans nor any of such trusts has been terminated, nor has there been any
"reportable event" (as that term is defined in Section 4043 of ERISA) with
respect thereto, during the last five years.

          (e) Except as set forth in Section 3.10(e) of the Company Disclosure
Schedule, neither the Company nor any of its Subsidiaries is a party to any
agreement, contract or arrangement that could result, separately or in the
aggregate, in the payment of any "excess parachute payments" within the meaning
of Section 280G of the Code.

          (f) Except as set forth in Section 3.10(f) of the Company Disclosure
Schedule, to the Knowledge of the Company, the disallowance of a deduction under
Section 162(m) of the Code for employee remuneration will not apply to any
amount paid or payable by the Company or any Subsidiary.

          (g) Except as would not have a Company Material Adverse Effect, no
liability under Title IV of ERISA has been incurred by any Commonly Controlled
Entity that has not been satisfied in full, and no condition exists that
presents a material risk to any Commonly Controlled Entity of incurring a
liability under such Title, other than liability for premiums due the Pension
Benefit Guaranty Corporation ("PBGC") (which premiums have been paid when due).
                               ----                                             
To the extent this representation applies to sections 4064, 4069 or 4204 of
Title IV of ERISA, it is made not only with respect to each Company Pension Plan
but also with respect to any employee benefit plan, program, agreement or
arrangement subject to Title IV of ERISA to which the Company or any Commonly
Controlled Entity made, or was required to make, contributions during the five
(5) year period ending on the Closing Date.  Except as would not have a Company
Material Adverse Effect, no Company Pension Plan or any trust established
thereunder has incurred any "accumulated funding deficiency" (as defined in
section 302 of ERISA and section 412 of the Code), whether or not waived, as of
the last day of the most recent fiscal year of each Company Pension Plan ended
prior to the Closing Date; and all contributions required to be made with
respect thereto (whether pursuant to the terms of any Company Pension Plan or
otherwise) on or prior to the Closing Date have been timely made.

          (h) With respect to each Company Benefit Plan not subject to United
States Law (a "Company Foreign Benefit Plan"), except as would not have a
               ----------------------------                              
Company Material Adverse Effect, (i) the fair market value of the assets of each
funded Company Foreign Benefit Plan, the liability of each insurer for any
Company Foreign Benefit Plan funded through insurance or the book reserve
established for any Company Foreign Benefit Plan, together with any accrued
contributions, is sufficient to procure or provide for the accrued benefit
obligations, as of the Effective Time, with respect to all current and former
participants in such plan according to the actuarial assumptions and valuations
most recently used to determine employer contributions to such Company Foreign
<PAGE>
 
                                      14

Benefit Plan and no transaction contemplated by this Agreement shall cause such
assets or insurance obligations or book reserve to be less than such benefit
obligations; and (ii) each Company Foreign Benefit Plan required to be
registered has been registered and has been maintained in good standing with the
appropriate regulatory authorities.

          (i) The Company and each of its Subsidiaries have not incurred any
liability under, and have complied in all respects with, the Worker Adjustment
and Retraining Notification Act of 1988 and the regulations promulgated
thereunder.

          SECTION 3.11.  Labor Matters.
                         ------------- 

          (a) Except as set forth in Section 3.11(a) of the Company Disclosure
Schedule, with respect to employees of the Company:  (i) to the Knowledge of the
Company, no senior executive or key employee has any plans to terminate
employment with the Company or any of its Subsidiaries; (ii) there is no unfair
labor practice charge or complaint against the Company or any of its
Subsidiaries pending or, to the Knowledge of the Company, threatened before the
National Labor Relations Board or any other comparable authority; (iii) there is
no demand for recognition made by any labor organization or petition for
election filed with the National Labor Relations Board or any other comparable
authority which, individually or in the aggregate, would have a Company Material
Adverse Effect; (iv) no grievance or any arbitration proceeding arising out of
or under collective bargaining agreements is pending and, to the Knowledge of
Company, no claims therefor have been threatened other than grievances or
arbitrations incurred in the ordinary course of business which, individually or
in the aggregate, would not have a Company Material Adverse Effect; (v) the
consummation of the Merger and related transactions contemplated by this
Agreement will not give rise to termination of any existing collective
bargaining agreement or permit any labor organization to reopen negotiations in
respect of wages, hours or working conditions under any such existing collective
bargaining agreements; and (vi) there is no litigation, arbitration proceeding,
governmental investigation, administrative charge, citation or action of any
kind pending or, to the Knowledge of the Company or any of its Subsidiaries,
proposed or threatened against the Company relating to employment, employment
practices, terms and conditions of employment or wages and hours which,
individually or in the aggregate, would have a Company Material Adverse Effect.

          (b) Except as identified in Section 3.11(b) of the Company Disclosure
Schedule, none of the Company nor any of its Subsidiaries has any collective
bargaining relationship or duty to bargain with any Labor Organization (as such
term is defined in Section 2(5) of the National Labor Relations Act, as
amended), and none of the Company nor any of its Subsidiaries has recognized any
labor organization as the collective bargaining representative of any of its
employees.

          SECTION 3.12.  Title to and Sufficiency of Assets.
                         ---------------------------------- 

          (a) As of the date hereof the Company and the Subsidiaries own, and as
of the Effective Time the Company and the Subsidiaries will own, good and
marketable title to all of their assets constituting personal property which is
material to their business (excluding, for purposes of this sentence, assets
held under leases), free and clear of any and all mortgages, liens,
encumbrances, charges, claims, restrictions, pledges, security interests or
impositions (collectively, "Liens"), except as set forth in the Company SEC
                            -----                                          
Reports or Section 3.12(a) of the Company Disclosure Schedule.  Such assets,
together with all assets held by the Company and the Subsidiaries under leases,
include all tangible and intangible personal property, contracts and rights
necessary or required for the operation of the businesses of the Company
Businesses.

          (b) As of the date hereof the Company and the Subsidiaries own, and as
of the Effective Time the Company and the Subsidiaries will own, good and
marketable title to all of their Real Estate which is material to such persons
(excluding, for purposes of this sentence, Real Estate leases), free and clear
of any and all Liens, except as set forth in the Company SEC Reports or in
Section 3.12(b) of the Company Disclosure Schedule
<PAGE>
 
                                      15

or such other Liens on Real Estate which would not, individually or in the
aggregate, have a Company Material Adverse Effect. Such Real Estate assets,
together with all Real Estate assets held by the Company and the Subsidiaries
under leases, are adequate for the operation of the Company Businesses as
presently conducted. The leases to all Real Estate occupied by the Company and
the Subsidiaries which are material to the operation of the Company Businesses
are in full force and effect and no event has occurred which with the passage of
time, the giving of notice, or both, would constitute a default or event of
default by the Company or any Subsidiary or, to the Knowledge of the Company,
any other person who is a party signatory thereto, other than such defaults or
events of default which, individually or in the aggregate, would not have a
Company Material Adverse Effect.

          SECTION 3.13.  Intellectual Property.  "Company Intellectual Property"

jointly and severally, represent and warrant to the Company that:

          SECTION 4.01. Organization and Qualification; Subsidiaries. Each of
                        --------------------------------------------          
Parent and Merger Sub is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation and has
the requisite power and authority and all necessary governmental approvals to
own, lease and operate its properties and to carry on its business as it is now

a foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that, individually or in the aggregate, would not have a Parent
Material Adverse Effect.  The term "Parent Material Adverse Effect" means any
                                    ------------------------------

heretofore furnished to the Company a complete and correct copy of the
Certificate of Incorporation and the By-laws, each as amended to date, of Parent
and Merger Sub. Such Certificates of Incorporation and By-laws are in full force
and effect. Neither Parent nor Merger Sub is in violation of any provision of
its respective Certificate of Incorporation or By-laws.

          SECTION 4.03. Parent Common Stock to Be Issued in the Merger. The
                        ----------------------------------------------

deliver this Agreement, to perform its obligations hereunder and to consummate
the Merger. The execution and delivery of this Agreement by Parent and Merger
Sub and the consummation by Parent and Merger Sub of the Merger have been duly
and validly authorized by all necessary corporate action and no other corporate
proceedings on the part of Parent or Merger Sub are necessary to authorize this
Agreement or to consummate the Merger (other than, with respect to the Merger,
the filing and recordation of appropriate merger documents as required by
Delaware Law). This Agreement has been duly and validly executed and delivered
by Parent and Merger Sub and, assuming the due authorization, execution and
delivery by the Company, constitutes a legal, valid and binding obligation of
each of Parent and Merger Sub enforceable against each of Parent and Merger Sub
in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

                        ------------------------------------------ 

          (a)   The execution and delivery of this Agreement by Parent and

other instrument or obligation to which Parent or Merger Sub is a party or by
which Parent or Merger Sub or any property or asset of either of them is bound
or affected, except for any such breaches or defaults which, individually or in
the aggregate, would not have a Parent Material Adverse Effect.

          (b)   The execution and delivery of this Agreement by Parent and
Merger Sub do not, and the performance of this Agreement by Parent and Merger
Sub will not, require any consent, approval, authorization or permit of, or
filing with or notification to, any governmental or regulatory authority,
domestic, foreign or supranational, except (i) for applicable requirements, if
any, of the Exchange Act, the Securities Act, Blue Sky Laws, state takeover
laws, the HSR Act, and the filing and recordation of appropriate merger
documents as required by Delaware Law and the rules of the NYSE, and (ii) where
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, is not reasonably likely to prevent or
materially delay consummation of the Merger, and would not, individually or in
the aggregate, have a Parent Material Adverse Effect.

respective periods indicated therein in accordance with United States generally
accepted accounting principles (subject, in the case of unaudited statements, to

with the Merger based upon arrangements made by or on behalf of Parent or Merger
Sub.

          (c)   (i) Each of Parent and the Company shall give (or shall cause
its respective subsidiaries to give) any notices to third parties and use, and
cause its respective subsidiaries to use, their reasonable efforts to obtain any
third party consents, (A) necessary, proper or advisable to consummate the
transactions contemplated in this Agreement, (B) disclosed or required to be
disclosed in the Company Disclosure Schedule or (C) required to prevent a
Company Material Adverse Effect from occurring prior to or after the Effective
Time or a Parent Material Adverse Effect from occurring after the Effective

      --------  -------
more of such third party consents (including those disclosed in Section 3.05(a)
and Section 3.05(b) of the Company Disclosure Schedule) shall not constitute a
condition precedent to Parent's obligation to consummate the Merger pursuant to
the terms of this Agreement or entitle Parent to delay the Effective Time.

          (ii)  In the event that Parent or the Company shall fail to obtain any
third party consent described in subsection (c)(i) above, it shall use its
reasonable efforts, and shall take any such actions reasonably requested by the
other party, to minimize any adverse effect upon the Company and Parent, their
respective subsidiaries, and their respective businesses resulting, or which
could reasonably be expected to result after the Effective Time, from the
failure to obtain such consent.

(including by way of furnishing non-public information or assistance), or take
any other action to facilitate knowingly, any inquiries or the making of any
proposal that constitutes, or may reasonably be expected to lead to, any

Company, after consultation with independent legal counsel (who may be the
Company's regularly engaged independent legal counsel), determines in good faith
that such action is necessary for the directors of the Company to comply with
their fiduciary duties to the Company or its stockholders under applicable law,
or (iv) terminating this Agreement and the transactions contemplated hereby in
accordance with Section 8.01(g) hereof.  The Company agrees not to release any
third party from, or waive any provision of, any confidentiality or standstill

"Competing Transaction" shall mean any of the following involving the Company or

          (b)   Provided that there has been no breach of Section 6.05(a) which
materially and adversely affects the rights of Parent contained herein or in the
Option and Voting Agreement, if the Board of Directors of the Company determines
that it has received a Superior Proposal (as defined below), the Board of
Directors may cause the Company to give to Parent a notice (a "Superior Proposal
                                                               -----------------

similar transaction, for consideration consisting of cash and/or securities,
more than 50% of the aggregate voting power or capital stock of the Company then
outstanding or all or substantially all the assets of the Company and otherwise
on terms and conditions to closing which the Board of Directors of the Company
determines in its good faith judgment (based on the advice of a financial
advisor of nationally recognized reputation and independent counsel) to be more

to the extent required, is then committed or which, in the good faith judgment
of the Board of Directors of the Company, is reasonably capable of being
obtained by such third party.

          SECTION 6.06.  Indemnification and Insurance.
                         -----------------------------

          (a)   Parent and the Surviving Corporation agree that, except as may
be limited by applicable Laws, for seven (7) years from and after the Effective
Time, the indemnification obligations set forth in the Company's Certificate of
Incorporation and the Company's By-Laws, in each case as of the date of this
Agreement, shall survive the Merger (and, prior to the Effective Time, Parent
shall cause the Certificate of Incorporation and By-laws of Merger Sub to
include such provisions) and shall not be amended, repealed or otherwise
modified after the Effective Time in any manner that would adversely affect the
rights thereunder of the individuals who on or at any time prior to the
Effective Time were entitled to indemnification thereunder with respect to
matters occurring prior to the Effective Time.

          (b)   The Surviving Corporation shall maintain in effect, for three
(3) years from and after the Effective Time, directors' and officers' liability
insurance policies covering the persons who are currently covered in their
capacities as such directors and officers by the Company's current directors'

existing insurance coverage with respect to matters occurring prior to the
Effective Time.

          (c)   Parent hereby agrees that, effective upon the consummation of
the Merger, it will guarantee the Surviving Corporation's obligations under
Section 6.06(a) and (b) of this Agreement and under Section 6.9(c) of the UNC

the Merger and the UNC Merger, it will guarantee the obligations of the
surviving corporation of the UNC Merger under Sections 6.9(a) and (b) of the UNC
Merger Agreement.

          (e)   In addition to, and not in lieu of the foregoing, Parent shall
indemnify, defend and hold harmless all officers and directors of the Company
(the "Company Indemnified Parties") and all officers and directors of UNC (the
      ---------------------------

currently in effect, from and against all liabilities, costs, expenses and
claims (including without limitation reasonable legal fees and disbursements,
which shall be paid, reimbursed or advanced by Parent in a manner consistent
with applicable provisions of Parent's By-laws) related to the Merger and other
transactions contemplated hereby, which may be asserted against the Indemnified
Parties from and after the date of this Agreement, other than liabilities
resulting from a breach of the fiduciary duties of any of such Indemnified
Parties; provided, however, that (i) Parent's obligations to the Company
Indemnified Parties under this Section 6.06(e) shall not be effective until
consummation of the Merger and (ii) Parent's obligations to the UNC Indemnified
Parties shall not be effective until the consummation of both the UNC Merger and
the Merger.

date of this Agreement until the Effective Time, each party hereto shall
promptly notify the other parties hereto of (a) the occurrence, or non-
occurrence, of any event the occurrence or non-occurrence of which would be
reasonably likely to cause any condition to the obligations of any party to
effect the Merger or the UNC Merger not to be satisfied, (b) the failure of the
Company or Parent, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it pursuant to this
Agreement which would be reasonably likely to result in any condition to the
obligations of any party to effect the Merger not to be satisfied, or (c) the
failure of UNC to comply with or satisfy any covenant, condition or agreement to
be complied with or satisfied by it pursuant to the UNC Merger Agreement (as
defined below) which would be reasonably likely to result in any condition to
the obligations of the Company to effect the transactions contemplated by the
UNC Merger Agreement not to be satisfied; provided, however, that the delivery

of any notice pursuant to this Section 6.07 shall not be deemed to be an
amendment of this Agreement or any Section in the Company Disclosure Schedule
and shall not cure any breach of any representation or warranty requiring
disclosure of such matter prior to the date of this Agreement.  No delivery of
any notice pursuant to this Section 6.07 shall limit or affect the remedies
available hereunder to the party receiving such notice, including the rights of
Parent under Section 7.02(a) and those of the Company under Section 7.03(a), in
the event that a representation or warranty made by the Company or Parent herein
shall not be true and correct (giving effect to any standards of materiality set
forth in such Sections) as of the date hereof or as of the date when made (if a
different date) and as of the Effective Time.

consult with each other before issuing any press release or otherwise making any
public statements with respect to this Agreement or any transaction contemplated
hereby.  Parent and the Company shall not issue any such press release or make
any such public statement without the prior consent of the other (which consent
shall not be unreasonably withheld), except as may be required by Law or any
listing agreement with the NYSE, the NASD or any national securities exchange to
which Parent or the Company is a party.  The parties have agreed on the text of
a joint press release by which Parent and the Company will announce the
execution of this Agreement.

to be an affiliate, as of the date of this Agreement, of the Company under Rule
145 of the Securities Act, a written agreement substantially in the appropriate
form attached hereto as Exhibit 6.11.  The Company shall use its reasonable best
efforts to cause the Merger to qualify, and shall not take any actions which
could prevent the Merger from qualifying, as a reorganization qualifying under
the provisions of Section 368(a) of the Code.

          SECTION 6.12.  Company Employee Stock Purchase Plan.  The Company
                         ------------------------------------              
shall take all actions necessary pursuant to the terms of the ESPP in order to

execution and delivery of this Agreement, the Company and UNC Incorporated, a

the Company intends, on the terms and conditions set forth therein, to acquire
UNC pursuant to a merger (the "UNC Merger").  Unless this Agreement shall have
                               ----------                                     
been terminated in accordance with its terms by Company or Parent, the Company

V of the Clean Air Act, as amended, with respect to operations at the Company's
Miami International Airport Facility and in connection therewith to ensure
continuation of present operating levels of such facility pending the issuance
of such permit.  Provided that the Company is using its reasonable best efforts
to obtain such permit, Parent hereby acknowledges that the failure to obtain
such permit shall not, in and of itself, be a breach of such covenant; provided
                                                                       --------

that, notwithstanding any disclosure of the failure to have such permit in this
Agreement, the Company Disclosure Schedule or otherwise, any adverse
consequences resulting or arising from the failure to have such permit may be

                         ------------------------------------------------------ 
The obligations of Parent and Merger Sub to consummate the Merger are subject to

     assumptions concerning, among other things, the actions of the stockholders

           GE TO ACQUIRE GREENWICH AIR SERVICES AND UNC INCORPORATED

        FAIRFIELD, CONN. -- March 10, 1997 -- General Electric Company and 
Greenwich Air Services, Inc. have signed a definitive agreement whereby GE will 
acquire Greenwich Air.

        Under the terms of the agreement, GE also obtains the rights to complete
Greenwich's acquisition of UNC Incorporated, also an aircraft engine services 
company, which announced in February plans to merge with Greenwich.

        The transactions have been approved by the boards of GE, Greenwich, and 
UNC.  The GE/Greenwich transaction is subject to approval by Greenwich's 
shareholders.  The Greenwich/UNC transaction is subject to approval by the 
shareholders of UNC.  Both transactions are subject to regulatory review.

        Eugene P. Coneso, Sr., chairman and chief executive officer of Greenwich
and its controlling share owner, has agreed to sell his shares of Greenwich to 
GE and has agreed to vote in favor of the transaction.

        The GE/Greenwich agreement calls for GE to acquire Greenwich through a 
combination of GE stock and cash valued at $530 million or $31 per share of 
Greenwich stock.  The acquisition of UNC by Greenwich will involve a cash 
transaction valued at an additional $345 million or $15 per share of UNC stock. 
As part of the transaction, GE will assume the debt of both acquired companies.

        "The acquisition of Greenwich/UNC will enable GE Engine Services to 
provide even greater customer value by broadening our capabilities and 
products," said Bill Vareschi, president and chief executive officer of GE 
Engine Services.  "This acquisition is an excellent complementary match between 
Greenwich's and UNC's capabilities and GE's current services and products.  It 
will bring GE a broader range of customers and will give GE a presence in the 
growing business jet aviation services sector."

        Eugene P. Coneso, Sr., chairman and chief executive officer of Greenwich
said:  "The merger of Greenwich Air into GE will result in the most efficient 
aircraft engine services company in the world and should be of great benefit to 
Greenwich's customers.  The merger will also present a great opportunity for all
of Greenwich's employees for greater advancement and financial security.  At 
the same time it will afford Greenwich's shareholders substantial value and the 
opportunity to receive GE stock on a tax-free basis, with the attendant ability 
to participate in the future value of GE stock, including the results of this 
merger.  As announced in our February 14, 1997 press release with regard
<PAGE>
 
to the UNC merger, the combined annual revenues of Greenwich Air and UNC would 
be nearly $1.8 billion."

        Dan A. Colussy, chairman, chief executive officer, and president of UNC,
said: "The acquisition of UNC by GE provides an excellent opportunity for UNC 
shareholders, customers, and employees. This link into the global, high 
technology capabilities of GE Engine Services will enhance service to our 
corporate, regional airline, and military customers, permitting a broader range 
of services with improved efficiencies."

        GE Engine Services, a wholly owned subsidiary of General Electric 
Company based in Evendale, Ohio is a provider of overhaul and repair of aircraft
engines, components, and accessories, with facilities in the United States, 
Wales, Brazil, and Singapore. With approximately 6,200 employees worldwide, GE 
Engine Services in 1996 had revenues of approximately $2.3 billion.

        Greenwich, based in Miami, Florida, is a diversified, independent jet
engine maintenance and overhaul company with nine locations, principally in the
United States and Scotland. Greenwich services primarily large commercial
aircraft engines, as well as marine and industrial aeroderivative engines
produced by the world's leading manufacturers. Greenwich has approximately 3,000
employees. In 1996, Greenwich purchased portions of Aviall, Inc., a jet engine
overhaul operation.

        UNC, based in Annapolis, Maryland, is a diversified, independent 
supplier of jet engine maintenance and overhaul with a major focus on smaller 
jet engines for corporate and military aircraft. UNC's Garrett Aviation Services
division, acquired in 1996, provides engine, airframe, and avionics services for
business jets and turboprop aircraft. UNC operates primarily at 20 U.S. 
locations and on 100 military bases in the U.S. and abroad. UNC employs 
approximately 7,000 people.

        The Greenwich/UNC Merger Agreement provides that, if the GE/Greenwich 
merger is not consummated, the Greenwich/UNC Merger announced on February 14, 
1997, will proceed on the same terms and conditions as previously announced.
