                          GREENWICH AIR SERVICES, INC.

                                  March 9, 1997

Item 5.  Other Events.

Agreement and Plan of Merger with General Electric Company.

      On March 9, 1997, Greenwich Air Services, Inc., a Delaware corporation
("Greenwich"), General Electric Company, a New York corporation ("GE"), and GB
Merger Corp., a Delaware corporation and wholly owned subsidiary of GE ("Merger
Sub"), entered into an Agreement and Plan of Merger of the same date (the "GE
Merger Agreement"), pursuant to which, at the Effective Time (as defined in the
GE Merger Agreement), Greenwich will become a wholly owned subsidiary of GE
through the merger of Greenwich with and into Merger Sub (the "GE Merger"). The
GE Merger Agreement provides, among other things, that as a result of the GE
Merger, (i) each share of Greenwich Class A common stock, par value $.01 per
share (the "Greenwich Class A Stock"), and (ii) each share of Greenwich Class B
common stock, par value $.01 per share (the "Greenwich Class B Stock" and,
together with the Greenwich Class A Stock, the "Greenwich Common Stock"), shall
be valued at $31.00 and converted into the right to receive that number of
shares of common stock, par value $.32 per share, of GE (the "GE Common Stock")
as shall be determined by dividing $31.00 by the Average Parent Share Price (as
defined below) (the "Stock Consideration"); provided, that such holder of
Greenwich Common Stock may elect to receive from GE, in lieu of all or part of
the Stock Consideration, cash in an amount equal to $31.00 per share of
Greenwich Common Stock (the "Cash Consideration").

      In order for the GE Merger to qualify as a tax-free reorganization in
respect of the Stock Consideration, the GE Merger Agreement also provides that
if the number of shares of Greenwich Common Stock for which holders elect to
receive Cash Consideration in lieu of Stock Consideration (the "Cash Election
Shares") exceeds 55% of the aggregate number of shares of Greenwich Common Stock
outstanding immediately prior to the Effective Time, the Cash Election Shares
shall be converted into the right to receive Stock Consideration and Cash
Consideration in a manner designed to ensure that no more than 55% of the
aggregate merger consideration will be Cash Consideration.

      The "Average Parent Share Price" is defined in the GE Merger Agreement as
the average of the last sales prices per share of GE Common Stock on The New
York Stock Exchange, Inc. Composite Tape for the 10 consecutive trading days
ending on the trading day which is five days prior to the Closing Date (as
defined in the GE Merger Agreement).


                                        2

      In addition, pursuant to the GE Merger Agreement, each option to purchase
Greenwich Class A Stock and/or Greenwich Class B Stock (a "Greenwich Stock
Option") outstanding at the Effective Time shall be canceled by Greenwich
immediately prior to the Effective Time, and each holder thereof shall be
entitled to receive at the Effective Time an amount (the "Option Spread") equal
to the product of (i) the number of shares of Greenwich Common Stock previously
subject to such Greenwich Stock Option and (ii) the excess, if any, of the Cash
Consideration over the exercise price per share of Greenwich Common Stock
previously subject to such Greenwich Stock Option. The Option Spread, after
reduction for applicable tax withholding, if any (the "Net Option Spread"),
shall be paid in cash or, if a holder of Greenwich Stock Options so elects in
writing at least 10 days prior to the Effective Time, in a number of shares of
GE Common Stock determined by dividing (i) the aggregate Net Option Spread
payable to such holder by (ii) the Average Parent Share Price.

      In connection with the GE Merger, certain stockholders of Greenwich
(collectively, the "Option Stockholders"), including Eugene P. Conese and Eugene
P. Conese, Jr., the Chairman of the Board and Chief Executive Officer and the
President and Chief Operating Officer of Greenwich, respectively, each only in
his or her capacity as a stockholder of Greenwich, and GE entered into a Stock
Option and Voting Agreement, dated March 9, 1997 (the "Option and Voting
Agreement"), pursuant to which the Option Stockholders (severally and not
jointly), among other things, granted to GE an irrevocable option (the "Option")
to purchase all, and not less than all, such Option Stockholder's Shares (as
defined in the Option and Voting Agreement) at a price per Share equal to a
number of shares (or fractional share) of GE Common Stock, having a Fair Market
Value (as defined in the Option and Voting Agreement) equal to $31.00 (the
"Purchase Price"). Each Option Stockholder may elect to receive up to 55% of the
aggregate Purchase Price for such Option Stockholder's Shares in cash, in the
same manner as provided for other stockholders in the GE Merger Agreement. The
Option may be exercised by GE, in whole but not in part, as to all and not less
than all Option Stockholders, during the period commencing on the date that the
waiting period under the Hart Scott Rodino Antitrust Improvements Act ("HSR")
applicable to the consummation of the purchase of the Shares pursuant to the
Option on the GE Merger has expired or been terminated and ending on the date
which is the earlier of (i) notice given by the Option Stockholders to GE at any
time after September 30, 1997 and (ii) the date of termination of the GE Merger
Agreement pursuant to the terms thereof by Greenwich in connection with certain
specified breaches thereof by GE.

      In addition, pursuant to the Option and Voting Agreement, each Option
Stockholder (severally and not jointly) also agreed to vote (or cause to be
voted) such Option Stockholder's Shares in favor of the approval and adoption of
the GE Merger Agreement, the GE Merger and all the transactions contemplated by
the GE Merger Agreement and the Option and Voting Agreement and otherwise in
such manner as may be necessary to consummate the GE Merger; provided, however,
that the Option Stockholders shall not be obligated to vote in favor of the
foregoing if the Board of Directors of Greenwich, in the exercise of its
fiduciary obligations and in accordance with the terms of the GE Merger
Agreement, has previously withdrawn and not reinstated its recommendation in
favor of the GE Merger because it has determined that Greenwich has received a
Superior Proposal (as defined in the GE Merger Agreement) from a


                                        3

<PAGE>

third party. Notwithstanding the foregoing, if GE has delivered an exercise
notice with respect to all of the Shares then owned by the Option Stockholders
and prior to such date Greenwich has established a record date for stockholder
action on the GE Merger, the Option Stockholders shall be obligated to vote in
favor of the GE Merger. If, and only if, any Option Stockholder fails to comply
with the voting provisions of the Option and Voting Agreement (as determined by
GE in its sole discretion), such failure will result in the irrevocable
appointment of GE, and each of its officers, as such Option Stockholder's
attorney and proxy, with full power of substitution, to vote and otherwise act
(by written consent or otherwise) with respect to such Option Stockholder's
Shares at any meeting of stockholders of Greenwich (whether annual or special)
or consent in lieu of any such meeting or otherwise, on the matters and in the
manner specified in the Option and Voting Agreement.

      Also in connection with the GE Merger, Eugene P. Conese, Sr., Chairman and
Chief Executive Officer of the Company, entered into a Consulting Agreement,
dated as of March 9, 1997, with GE, pursuant to which, among other things, Mr.
Conese agreed, subject to the completion of the GE Merger, to act as a
consultant to the Company and not to compete with the engine services businesses
of GE. Mr. Conese's engagement under the Consulting Agreement shall commence as
of the Effective Time of the GE Merger and shall terminate on the fifth
anniversary thereof (the "Consulting Period"). As compensation for the
non-competition and related covenants contained in the Consulting Agreement and
the consulting services to be performed, (i) GE shall pay Mr. Conese a fee each
year at the annual rate of $1.0 million and (ii) GE shall make a $1.0 million
payment each year of the Consulting Period in the name of Mr. Conese to a
charitable organization chosen by Mr. Conese.

Amended and Restated Agreement and Plan of Merger with UNC Incorporated.

      On March 9, 1997, Greenwich, UNC Incorporated, a Delaware corporation
("UNC"), and Condor Acquisition Corporation, a Delaware corporation and wholly
owned subsidiary of Greenwich ("Condor"), entered into an Amended and Restated
Agreement and Plan of Merger of the same date (the "UNC Merger Agreement"),
pursuant to which the parties have agreed to restructure the transactions
contemplated by the Agreement and Plan of Reorganization, dated February 13,
1997, by and among the parties (the "Prior Agreement"). The UNC Merger Agreement
amends and restates the Prior Agreement to provide that UNC will become a wholly
owned subsidiary of Greenwich through the merger of Condor with and into UNC
(the "UNC Merger"). Pursuant to the proposed terms of the UNC Merger (i) each
share of UNC common stock, par value $.20 per share, of UNC (the "UNC Common
Stock"), shall be converted into the right to receive $15.00 in cash (the "UNC
Merger Consideration") payable, without interest, to the holder of such share of
UNC Common Stock, and (ii) each share of UNC Series B preferred stock, par value
$1.00 per share (the "UNC Series B Preferred Stock"), 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 Preferred Stock is
convertible immediately before the Effective Time (as defined in the UNC Merger
Agreement).


                                        4

<PAGE>

      In addition, pursuant to the UNC Merger Agreement, each option to purchase
UNC Common Stock (a "UNC Stock Option") outstanding 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 (i) the aggregate number
of shares of UNC Common Stock issuable upon exercise of such unexercised UNC
Stock Option (the "Unexercised Option Shares") by (ii) the difference between
$15.00 and the applicable exercise price per share attributable to such
Unexercised Option Shares.

      In the event that the GE Merger Agreement is terminated for any reason,
the UNC Merger Agreement shall, without any action by any party thereto, be
further amended, restated and modified, so that all of the terms and conditions
set forth in the Prior Agreement shall be deemed to be the terms and conditions
of the UNC Merger Agreement (with certain minor exceptions), and the UNC Merger
shall proceed forward under the terms and conditions of the UNC Merger Agreement
as so amended, restated and modified.

      The GE Merger Consideration, the UNC Merger Consideration, as well as the
other terms and conditions of the GE Merger Agreement and the UNC Merger
Agreement, were determined as a result of arm's-length negotiations among
representatives of the parties to each of the GE Merger Agreement and UNC Merger
Agreement. Consummation of the transactions contemplated by the GE Merger
Agreement and the UNC Merger Agreement are subject to a number of conditions,
including, without limitation, approval of certain regulatory authorities,
approval of the GE Merger Agreement by the stockholders of Greenwich entitled to
vote thereon, and approval of the UNC Merger Agreement by the stockholders of
UNC entitled to vote thereon.

      The information set forth above is qualified in its entirety by reference
to (i) the GE Merger Agreement, a copy of which is attached hereto as Exhibit 1,
(ii) the Option and Voting Agreement, a copy of which is attached hereto as
Exhibit 2, (iii) the Consulting Agreement, a copy of which is attached hereto as
Exhibit 3, (iv) the UNC Merger Agreement, a copy of which is attached hereto as
Exhibit 4 and (v) the press release issued by GE, Greenwich and UNC on March 10,
1997, a copy of which is attached hereto as Exhibit 5.

            AGREEMENT AND PLAN OF MERGER dated March 9, 1997 (this "Agreement")
among GENERAL ELECTRIC COMPANY, a New York corporation ("Parent"), GB MERGER
CORP., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger
Sub"), and GREENWICH AIR SERVICES, INC., a Delaware corporation (the "Company").

            WHEREAS, the parties hereto desire to cause the Company, upon the
terms and subject to the conditions of this Agreement and in accordance with the
General Corporation Law of the State of Delaware ("Delaware Law"), to merge with
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
hereby and recommended unanimously that the holders of shares of Company Class A
Stock (as such term is defined in Section 2.01) approve and adopt this
Agreement;

            WHEREAS, the Board of Directors of Parent has determined that the
Merger is in the best interests of Parent and its stockholders and, as sole
stockholder of Merger Sub, has approved and adopted this Agreement and the
transactions contemplated hereby;

            WHEREAS, for federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization under the provisions of Section 368(a)
of the United States Internal Revenue Code of 1986, as amended (the "Code"); and

            WHEREAS, as a condition and inducement to Parent's and Merger Sub's
entering into this Agreement and incurring the obligations set forth herein,
concurrently with the execution and delivery of this Agreement, Parent is
entering into a Stock Option and Voting Agreement with certain stockholders of
the Company, dated the date hereof (the "Option and Voting Agreement"), pursuant
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
have granted to Parent an option to acquire their shares of Company Common Stock
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
hereby, Parent, Merger Sub and the Company hereby agree as follows:

                                    ARTICLE I

                                   THE MERGER

            SECTION 1.01. The Merger. Upon the terms and subject to the
conditions set forth in Article VII, and in accordance with Section 251 of
Delaware Law, at the Effective Time (as defined below), the Company shall be
merged with and into Merger Sub. As a result of the Merger the separate
corporate existence of the Company shall cease, and Merger Sub shall be the
surviving corporation of the Merger (the "Surviving Corporations").

            SECTION 1.02. Effective Time; Closing. As promptly as practicable,
and in no event later than five business days after the satisfaction or, if
permissible, waiver of the conditions set forth in Article VII (other than those
conditions that can only be satisfied on the Closing Date (as defined below)),
the parties hereto shall cause the Merger to be consummated by filing a
certificate of merger (the "Certificate of Merger") with the Secretary of State
of the State of Delaware, in such form as is required by, and executed in
accordance with, Section 251 of Delaware Law. The term "Effective Time" means
the date and time of the filing of the Certificate of Merger with the Secretary
of State of the State of Delaware (or such later time as may be agreed by the
parties hereto and specified in the Certificate of Merger). Immediately prior to
the filing of the Certificate of Merger, a closing will be held at the offices
of Shearman & Sterling, 599 Lexington Avenue, New York, New York (or such other
place as the partial may agree) (the date on which such closing takes place
being the Closing Date.).

            SECTION 1.03. Effect of the Merger. At the Effective Time, the
effect of the Merger shall be as provided in the applicable provisions of
Delaware Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities, obligations, restrictions, disabilities
and duties of each of the Company and Merger Sub shall become the debts,
liabilities, obligations, restrictions, disabilities and duties of the Surviving
Corporation.

            SECTION 1.04. Certificate of Incorporation: By-laws.

            (a) Subject to the terms of Section 6.06, at the Effective Time, the
Certificate of Incorporation of the Surviving Corporation shall be the
Certificate of Incorporation of Merger Sub as in effect immediately prior to the
Effective Time, except that Article I thereof shall be amended as of the
Effective Time to read as follows: "the name of the Corporation is Greenwich Air
Services, Inc."

            (b) Subject to the terms of Section 6.06, at the Effective Time, the
By-laws of Merger Sub, as in effect immediately prior to the Effective Time,
shall be the By-laws of the Surviving Corporation until thereafter amended as

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 (a) 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,

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.

prior to the Election Deadline. Any holder of Company Common Stock may at any
time prior to the Election Deadline revoke his election and withdraw his
Certificates deposited with the Exchange Agent by written notice to the Exchange
Agent received by the Election Deadline. As soon as practicable after the
Election Deadline, the Exchange Agent shall determine the avocation of the cash
portion of the Merger Consideration and the stack portion of the Merger
Consideration and shall notify Parent of its determination. Promptly after such
notification, Parent shall issue a press release announcing in reasonable detail
the results of the Exchange Agent's avocation of the Merger Consideration.

            (f) Deemed Non-Election. For the purposes hereof, a holder of record
of Company Common Stock who does not submit a Form of Election which is received
and accepted as such by the Exchange Agent prior to the Election Deadline shall

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

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 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 interests subject to and in accordance with the terms of Sections
2.04(b), (c) and (d).

which such deduction and withholding was made by the Surviving Corporation or
Parent, as the case may be.

            STOCK OPTION AND VOTING AGREEMENT dated March 9, 1997, among the
several stockholders of GREENWICH AIR SERVICES, INC., a Delaware corporation
(the "Company"), that are parties hereto (each, a "Stockholder" and,
collectively, the "Stockholders"), and GENERAL ELECTRIC COMPANY, a New York
corporation ("Parent").

            WHEREAS, Parent and GB Merger Corp., a Delaware corporation and a
wholly owned subsidiary of Parent ("Merger Sub"), propose to enter into an
Agreement and Plan of Merger dated the date hereof (as amended from time to
time, the "Merger Agreement"; capitalized terms being used herein as defined
therein unless otherwise defined herein), with the Company, which provides,
among other things, that the Company will merge with and into Merger Sub (the
"Merger");

            WHEREAS, as of the date hereof, each Stockholder is the record and
beneficial owner of the number of shares of Class A Common Stock, par value $.01
per share, of the Company (the "Class A Common Stock"), and Class B Common
Stock, par value $.01 per share, of the Company (the "Class B Common Stock," and
together with the Class A Common Stock, the "Company Common Stock") set forth on
the signature page hereof beneath such Stockholder's name (with respect to each
Stockholder, such Stockholder's "Existing Shares" and, together with any shares
of Company Common Stock acquired after the date hereof, whether upon the
exercise of warrants, options, conversion of convertible securities or
otherwise, such Stockholder's "Shares"); and

            WHEREAS, as a condition to the willingness of Parent to enter into
the Merger Agreement, Parent has requested that the Stockholders agree, and in
order to induce Parent to enter into the Merger Agreement, the Stockholders have
agreed, to enter into this Agreement.

            NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and intending to be legally bound
hereby, the parties hereto agree as follows:

                                    ARTICLE I

                                VOTING AGREEMENT

            SECTION 1.01. Voting Agreement. Each Stockholder, severally and not
jointly, hereby agrees that, from and after the date hereof and until this
Agreement shall have been terminated in accordance with Article VII hereof, at
any meeting of the stockholders of the Company, however called, and in any
action by consent of the stockholders of the Company, such Stockholder will vote
(or cause to be voted) such Stockholder's Shares: (a) in favor of the approval
and adoption of the Merger Agreement, the Merger 

<PAGE>

and all the transactions contemplated by the Merger Agreement and this Agreement
and otherwise in such manner as may be necessary to consummate the Merger; (b)
except as otherwise agreed to in writing in advance by Parent, against any
action, proposal, agreement or transaction that would result in a breach of any
covenant, obligation, agreement, representation or warranty of the Company
contained in the Merger Agreement (whether or not theretofore terminated) or of
the Stockholder contained in this Agreement; and (c) against any action,
proposal, agreement or transaction (other than the Merger Agreement or the
transactions contemplated thereby) that could result in any of the conditions to
the Company's obligations under the Merger Agreement (whether or not theretofore
terminated) not being fulfilled or that is intended, or could reasonably be
expected, to impede, interfere or be inconsistent with, delay, postpone,
discourage or adversely affect the Merger Agreement (whether or not theretofore
terminated), the Merger or this Agreement, including, but not limited to, any
Competing Transaction (as such term is defined in the Merger Agreement);
provided, however, that the Stockholders shall not be obligated to vote in favor
of the Merger pursuant to clause (a) above if the Board of Directors of the
Company has previously withdrawn and not reinstated its recommendation in favor
of the Merger in the manner prescribed in Section 6.05(b) of the Merger
Agreement. Notwithstanding anything to the contrary contained in the proviso in
the immediately preceding sentence, if Parent has delivered an Exercise Notice
with respect to all of the Shares then owned by the stockholders and prior to
such date the Company has established a record date for Shareholder action on a
matter covered by clause (a) above, the Stockholders shall be obligated to vote
in favor of the Merger pursuant to clause (a) above. Such Stockholder shall not
enter into any agreement or understanding with any person or entity to vote such
Stockholder's shares or give instructions in any manner inconsistent with this
Section 1.01. The Stockholder acknowledges receipt and review of a copy of the
Merger Agreement.

            SECTION 1.02. Irrevocable Proxy. If, and only if, any Stockholder
fails to comply with the provisions of Section 1.01 (as determined by Parent in
its sole discretion), such Stockholder hereby agrees that such failure shall
result, without any further action by such Stockholder, in the irrevocable
appointment of Parent, and each of its officers, as such Stockholder's attorney
and proxy pursuant to the provisions of Section 212(c) of the General
Corporation Law of the State of Delaware, with full power of substitution, to
vote and otherwise act (by written consent or otherwise) with respect to such
Stockholder's Shares at any meeting of stockholders of the Company (whether
annual or special and whether or not an adjourned or postponed meeting) or
consent in lieu of any such meeting or otherwise, on the matters and in the
manner specified in Section 1.01. THIS PROXY AND POWER OF ATTORNEY ARE
IRREVOCABLE AND COUPLED WITH AN INTEREST AND, TO THE EXTENT PERMITTED UNDER
APPLICABLE LAW, SHALL BE VALID AND BINDING ON ANY PERSON TO WHOM A STOCKHOLDER
MAY TRANSFER ANY OF HIS SHARES IN 

<PAGE>

BREACH OF THIS AGREEMENT. Each Stockholder hereby revokes all other proxies and
powers of attorney with respect to such Stockholder's Shares that may have
heretofore been appointed or granted, other than the irrevocable proxy and
voting trust granted by Anna Mae Conese in favor of Eugene P. Conese, Sr. (the
"Irrevocable Proxy"), and no subsequent proxy or power of attorney shall be
given or written consent executed (and if given or executed, shall not be
effective) by any Stockholder with respect thereto. All authority herein
conferred or agreed to be conferred shall survive the death or incapacity of any
Stockholder and the termination of the Irrevocable Proxy and any obligation of
the Stockholder under this Agreement shall be binding upon the heirs, personal
representatives, successors and assigns of such Stockholder.

                                   ARTICLE II

                                   THE OPTION

            SECTION 2.01. Grant of Option. Each Stockholder, severally and not
jointly, hereby grants to Parent an irrevocable option (each, an "Option" and,
collectively, the "Options") to purchase all, and not less than all, such
Stockholder's Shares at a price per Share equal to a number of shares (or
fractions of a share) of Parent's common stock, par value $0.32 per share
("Parent Common Stock"), having a Fair Market Value equal to $31.00 (the
"Purchase Price"). For purposes of this Section 2.01, "Fair Market Value" means
the average of the closing prices of a share of Parent Common Stock on the New
York Stock Exchange for each of the 10 trading days ending on the trading day
next preceding the Closing Date (as defined below). Each Stockholder may elect
to receive up to 55% of the aggregate Purchase Price for all of such
Stockholder's Shares in the same manner as is provided in Section 2.03(b) of the
Merger Agreement.

            SECTION 2.02. Exercise of Option. (a) The Options may be exercised
by Parent, in whole but not in part as to all but not less than all
Stockholders, during the period commencing on the date that the waiting period
applicable to the consummation of the purchase of the Shares pursuant to the
Options on the Merger has expired or been terminated and ending on the date
which is the earlier of (i) upon notice given by the Stockholders or Parent
after September 30, 1997 and (ii) the date of termination of the Merger
Agreement pursuant to Section 8.01 thereof by the Company in connection with a
Terminating Parent Breach.

            (b) If Parent wishes to exercise the Options, Parent shall send a
written notice (the "Exercise Notices) to each Stockholder of its intention to
exercise the Options, specifying the place, and, if then known, the time and the
date (the "Closing Date") of the closing (the "Closing") of the purchase. The
Closing Date shall occur on the third business day (or such longer period as may
be required by applicable law or regulation) after the later 

<PAGE>

of (i) the date on which such Exercise Notice is delivered and (ii) the
satisfaction of the conditions set forth in Section 2.02(e).

            (c) At the Closing, each Stockholder shall deliver to Parent (or its
designee) all of such Stockholder's Shares by delivery of a certificate or
certificates evidencing such Shares in the denominations designated by Parent in
its exercise notice delivered pursuant to Section 2.02(b), duly endorsed to
Parent or accompanied by stock powers duly executed in favor of Parent, with all
necessary stock transfer stamps affixed.

            (d) At the Closing, Parent shall pay the Purchase Price by delivery
to each Stockholder of certificates representing the applicable number of shares
of Parent Common Stock determined in accordance with Section 2.01 hereof
registered in the name of such Stockholder.

            (e) The Closing shall be subject to the satisfaction of each of the
following conditions:

                  (i) no court, arbitrator or governmental body, agency or
      official shall have issued any order, decree or ruling and there shall not
      be any statute, rule or regulation, restraining, enjoining or prohibiting
      the consummation of the purchase and sale of the Shares pursuant to the
      exercise of the Options; and

                  (ii) any waiting period applicable to the consummation of the
      purchase and sale of the Shares pursuant to the exercise of the Options
      under the HSR Act shall have expired or been terminated.

                                   ARTICLE III

creation of a lien or encumbrance on any of the Shares owned by such Stockholder

consideration of not less than $31.00 per share of Company Common Stock in the
form of Shares of Parent Stock or (b) make an offer to the Company's
stockholders to acquire all shares of Company Common Stock not owned by Parent
and its subsidiaries for a price of not less than $31.00 per share in the form
of shares of Parent Stock; in either such case with the opportunity to receive
cash in the manner contemplated by Section 2.03 of the Merger Agreement.
Parent's obligation to make such proposal or offer shall be subject to there not
being any order, statute, rule, regulation, executive order, stay, decree,
judgment or injunction enacted, entered, issued, promulgated or enforced by any
Governmental Authority or a court of competent jurisdiction which has the effect
of making such proposal or offer illegal or otherwise prohibiting consummation
of such proposal or offers. Parent's obligation to consummate any such proposal
or offer shall be subject to the satisfaction of the conditions set forth in
Section 7.01(c), (d) and (e) and 7.02(b) and (c) of the Merger Agreement.

            SECTION 6.02. Registration of Parent Shares. To the extent that the
Stockholders are unable to sell the Shares of Parent Stock received in
connection with the purchase and sale of the Shares hereunder or pursuant to the
Merger, pursuant to Rule 144 or Rule 145 under the Securities Act or another
applicable exemption from the registration requirements of the Securities Act,
Parent, upon the written request of the Stockholders, shall use its reasonable
best efforts to cause the Shares designated in such notice to be registered
under the Securities Act in order to permit the proposed sale of such Shares.
Notwithstanding anything to the contrary in the immediately preceding sentence,
(i) Parent shall not be obligated to register any Shares designated in a notice
from the Stockholders if such Shares are not reasonably anticipated to have an
aggregate price to the public in excess of $15 million and (ii) the Stockholders
shall be entitled to submit no more than three notices to Parent in the three
year period following the Closing. In connection with any such registration,
Parent and Stockholders shall enter into an agreement on terms and conditions
customarily contained in registration rights agreements relating to
circumstances similar to those set forth herein.

thereof, (c) the date of termination of the Merger Agreement pursuant to Section
8.01(d) thereof by the Company in connection with a Terminating Parent Breach
and (d) the date of termination of the Merger Agreement pursuant to Section
8.01(b)(i) or (ii) thereof. Nothing in this Section 7.01 shall relieve any party
of liability for any breach of this Agreement.

                                  ARTICLE VIII

                                  MISCELLANEOUS

            SECTION 8.01. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of this Agreement is not affected in any manner materially adverse to
any party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a mutually acceptable manner in order that the
terms of this Agreement remain as originally contemplated to the fullest extent
possible.

(b) waive any inaccuracies in the representations and warranties of the other
party contained herein or in any document delivered by the other party pursuant
hereto or (c) waive compliance with any of the agreements or conditions of the
other party contained herein. Any such extension or waiver shall be valid only
if set forth in an instrument in writing signed by the party to be bound
thereby. Any waiver of any term or condition shall not be construed as a waiver
of any subsequent breach or a subsequent waiver of the same term or condition,
or a waiver of any other term or condition, of this Agreement. The failure of
any party to assert any of its rights hereunder shall not constitute a waiver of
any of such rights.

and construed in accordance with, the laws of the State of Delaware applicable
to contracts executed in and to be performed in that State. All actions and

                              CONSULTING AGREEMENT

            CONSULTING AGREEMENT (the "Agreement") dated as of March 9, 1997, by
and between General Electric Company, a New York corporation ("Parent"), and
Eugene P. Conese, Sr.("Consultant").

            WHEREAS, Parent, GB Merger Corp., and Greenwich Air Services, Inc.,
a Delaware corporation (the "Company"), have entered into a Merger Agreement,
dated as of the date hereof (the "Merger Agreement"), pursuant to which the
Company will merge with and into GB Merger Corp. (the "Merger"); and

            WHEREAS, Consultant has served as Chief Executive Officer and
Chairman of the Board of Directors of the Company and will resign from such
positions effective as of the consummation of the Merger; and

            WHEREAS, Parent wishes to retain Consultant to provide consulting
and advisory services following his resignation from the Company and Consultant
has agreed to provide such services on the conditions set forth herein; and

            WHEREAS, in connection with the Merger, the parties desire to enter
into this Agreement, to be effective at the "Effective Time" (as defined in the
Merger Agreement);

            NOW, THEREFORE, in consideration of the mutual covenants in this
Agreement, the parties hereby agree as follows:

      1. Effectiveness of Agreement and Consulting Engagement.

            1.1. Effectiveness of Agreement. This Agreement shall become
effective as of the Effective Time. In the event that the Merger is not
consummated, this Agreement shall be null and void.

            1.2. Consulting Engagement. (a) Parent hereby agrees to engage
Consultant as an independent contractor and advisor on the terms and conditions
set forth herein and Consultant hereby accepts such engagement with Parent.
Consultant's services hereunder shall consist of rendering to the best of his
ability such consulting and advisory services in connection with the Company
Businesses (as such term is defined in the Merger Agreement), as may reasonably
be requested from time to time by the Chief Executive Officer or the Board of
Directors of Parent (the "Board"), or the designee of either thereof, and to
facilitate the successful transition of the Company from its current form to a
business owned by Parent; provided, that (i) Consultant shall not be required to
travel or relocate, and (ii) the requirement that Consultant devote time to
perform services pursuant to this Agreement shall be subject to the time
available to Consultant during normal business hours after the conduct by
Consultant of his other businesses, which shall take precedence in all cases.
Consultant shall make himself available on 

<PAGE>

a reasonable basis from time to time to provide such services, but there shall
be no established schedule for Consultant's services and he shall not be
required to devote any minimum number of days to such services. Parent expressly
acknowledges and agrees that Consultant's primary occupation and business
interests shall be conducted by Consultant in endeavors other than Consultant's
services pursuant to this Agreement.

      (b) Notwithstanding anything contained herein to the contrary, Consultant
may elect to have his rights and obligations hereunder assigned to a subchapter
S corporation (the "S Corp") of which he is a principal shareholder, provided
that (i) the S Corp shall rely exclusively on Consultant to act on its behalf in
providing the consulting services required hereunder, (ii) the S Corp executes a
writing in which it expressly agrees to be bound by this Agreement as
"Consultant" hereunder, and (iii) Consultant, in his individual capacity, shall
continue to be bound by the restrictive covenants contained in Section 5 hereof
Following any assignment of rights and obligations to the S Corp in accordance
with this Section 1.2(b), except as provided above or as the context would
otherwise require, all references to "Consultant" hereunder shall be deemed to
refer to the S Corp.

            1.3. Independent Contractor Status. Consultant is an independent
contractor under this Agreement and shall be free to exercise his discretion and
judgment as to the methods and means of performing the services performed
hereunder. Consultant is not an employee of Parent, will not by virtue of this
Agreement be considered an employee of Parent for any purpose, and will not be
entitled to any benefits, rights, or privileges provided by Parent to its
employees under any Parent welfare or other benefit plans, including, without
limitation, Parent insurance, pension, and savings and security plans.
Consultant shall be solely responsible for the payment of any and all of his
required contributions and/or taxes including without limitation: federal, state
and/or local income taxes and withholding; workers' compensation insurance;
unemployment contribution insurance; and social security taxes. Consultant
represents that he is complying and will continue to comply with all federal,
state and local requirements regarding employment taxes and income taxes, and
will indemnify and hold Parent harmless from any action by governmental agencies
arising out of his failure to perform any such responsibilities.

            1.4. No Agency. Nothing contained in this Agreement shall be
construed as creating an agency relationship between Parent or any of its
subsidiaries or affiliates ("Affiliates") and Consultant and, without Parent's
prior written consent, Consultant shall have no authority hereunder to bind
Parent or any of its Affiliates or make any commitments on Parent's or any of
its Affiliate's behalf. Consultant shall not take any action in connection with
his rendering of services hereunder which he reasonably believes would cause any
third party to assume that he has such authority.

<PAGE>

      2. Compensation.

            2.1. Consulting and Non-Competition Fee. As compensation for the
consulting services to be performed, and the restrictive covenants to be
complied with pursuant to Section S. by Consultant hereunder, (i) Parent shall
pay Consultant a fee each year of the Consulting Period which shall be payable
in equal installments, no less frequently than quarterly in advance, at the
annual rate of $1 million and (ii) Parent shall make a $1 million payment each
year of the Consulting Period in the name of Consultant to a charitable
organization chosen by Consultant (the "Fees").

            2.2. Expenses. Pursuant to Parent's customary policies in force at
the time of payment, Consultant shall be promptly reimbursed for all authorized
expenses properly and reasonably incurred by him on behalf of Parent or its
Affiliates in the performance of his duties hereunder upon presentation of
appropriate documentation consistent with Parent's policies concerning expense
reimbursement.

      3. Consulting Period.

            Consultant's engagement under this Agreement shall commence as of
the Effective Time, and shall terminate on the fifth anniversary thereof (the
"Consulting Period"), unless terminated earlier pursuant to Section 4. Section 5
shall survive any termination of this Agreement and shall remain in full force
and effect. In the event Consultant dies or becomes permanently disabled during
the Consulting Period, the Fees shall continue to be paid to him or, in the
event of his death, to his beneficiary, until the end of the Consulting Period
in accordance with the terms of this Agreement.

      4. Termination.

            4.1. Termination by Parent for Cause. (a) The Consulting Period may
be terminated at any time by Parent for Cause (as defined below). Upon such a
termination, Parent shall have no obligation to Consultant other than the
payment of Consultant's earned but unpaid compensation through the effective
date of such termination and reimbursement of authorized expenses pursuant to
Section 2.2 of this Agreement.

            (b) For purposes of this Agreement, the term "Cause" shall mean
either of the following:

                  (i) Consultant's conviction of a criminal offense arising out
      of a breach of trust, fraud, or embezzlement against Parent; or

                  (ii) Any breach by Consultant of any material provision of
      Section 5 of

<PAGE>

      5.    Restrictive Covenants.

            5.1. Confidentiality. Consultant understands and acknowledges that
during his employment with the Company prior to this Agreement and through the
course of his consulting engagement pursuant to this Agreement, he has had and
will have access to and has learned and will learn (i) information proprietary
to Parent and its Affiliates that concerns the operation and methodology of the
Company Businesses as the same are hereafter conducted by the Parent and its
Affiliates (the "Aircraft Engine Services Business") or (ii) other information
proprietary to Parent and its Affiliates, including, without limitation, trade
secrets, processes, patent and trademark applications, product development,
price, customer and supply lists, pricing and marketing plans, policies and
strategies, details of client and consultant contracts, operations methods,
product development techniques, business acquisition plans, new personnel
acquisition plans and all other confidential information with respect to the
Aircraft Engine Services Business (collectively, "Proprietary Information").
Consultant agrees that, at all times (including following termination of the
Consulting Period), he will keep confidential and will not disclose directly or
indirectly any such Proprietary Information to any third party, except as
required to fulfill his duties hereunder, and will not misuse, misappropriate or
exploit such Proprietary Information in any way. The restrictions contained
herein shall not apply to any information which (a) was already available to the
public at the time of disclosure, or subsequently become available to the
public, otherwise than by breach of this Agreement, or (b)was disclosed due to a
requirement of law. Upon any termination of the Consulting Period, Consultant
shall promptly return to Parent and its Affiliates all documents, computer
disks, records, notebooks and similar repositories of any Proprietary
Information in his possession, including copies thereof.

            5.2. Restrictions on Competitive Employment. (a) During the period
beginning on the Effective Time and ending one year after the cessation of the
consulting engagement of Consultant for any reason (the "Restricted Period"),
Consultant shall not (as principal, agent, employee, consultant or otherwise),
anywhere worldwide, directly or indirectly, without the prior written approval
of Parent, engage in activities for, or render services to (including, without
limitation, computer programming, data entry, sales or product development), any
firm or business (i) materially engaged in direct or indirect competition with
the Company, the Parent and its Affiliates in the business of (x) repair and
overhaul of aircraft and aeroderivative gas turbine engines, components,
accessories and structural flight control services or (y) sale and distribution
of aircraft and aeroderivative gas turbine engines, components, assemblies,
modules and units of Aircraft Engine Services Business whether or not in the
geographic areas in which such lines of business are currently conducted by 

<PAGE>

the Company, the Parent, or its Affiliates (the "Core Aircraft Engine Services
Business"), (ii) materially engaged in developing products or services
competitive with those of the Core Aircraft Engine Services Business (all of the
businesses in clauses (i) and (ii) collectively, the "Competitive Business").
Notwithstanding the foregoing, (x) Consultant may have an interest consisting of
publicly traded securities constituting less than 5% percent of any class of
publicly traded securities in any public company engaged in a Competitive
Business so long as he is not employed by and does not consult with, or become a
director of or otherwise engage in any activities for, such company, and (y)
Consultant may continue to operate World Air Leases, it being understood and
agreed that the business of World Air Leases shall not be considered a
Competitive Business hereunder to the extent that it continues to engage in the
kinds of activities in which it is engaged as of the date hereof Notwithstanding
anything contained in this Section 5, Consultant agrees that Consultant shall
not, at any time during the Restricted Period, deliberately take any action
which (I) would interfere with any contractual or customer relationships of
Parent or its Affiliates in respect of the Aircraft Engine Services Business, or
any relationship with the employees of, or vendors or contractors to, Parent or
its Affiliates in respect of the Aircraft Engine Services Business, or (II)
would result in a material diminution of business to Parent or its Affiliates in
respect of the Core Aircraft Engine Services Business.

            (b) During the Restricted Period (or, if shorter, until the fifth
anniversary of the Effective Time), Consultant shall not pursue, assist, or
become otherwise involved in any capacity with any transaction or proposed
transaction relating to (x) the repair and overhaul of aircraft and
aeroderivative gas turbine engines, components, accessories and structural
flight control services or (y) the sale and distribution of aircraft and
aeroderivative gas turbine engines, components, assemblies, modules and units
which Consultant participated in or was first advised of in connection with the
performance of his services as Consultant under this Agreement unless Consultant

if required by the DGCL, or becomes ineligible for such appraisal. If a holder
of Dissenting Shares shall withdraw


                                      -13-

<PAGE>

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.

      Section 2.3. Surrender of Certificates: Stock Transfer Books. (a) Before
the Effective Time, Merger Sub shall designate a bank or trust company to act as
agent (the "Paying Agent") for the holders of shares of UNC Stock in 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


                                      -14-

<PAGE>

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.

      Section 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
issuable upon exercise of such unexercised UNC Stock Options (the "Unexercised
Option Shares") by (b) the difference between $15.00 and the applicable exercise
price per share attributable to such Unexercised Option Shares (the "Spread").

Business (excluding, for purposes of this sentence, Real Estate leases), free
and clear of any and all mortgages, liens, encumbrances, charges, claims,
restrictions, pledges, security interests or impositions, except as disclosed in

to the Knowledge of UNC, any other Person who is a party signatory thereto.

of each of the Material Contracts to which any UNC Company is a party that is to
be performed by any of them at or before the date hereof, (ii) all of such UNC
Material Contracts are in full force and effect and no event has occurred which,

UNC Material Contract to terminate the same or declare a default or event of
default thereunder; (iii) neither UNC or any UNC Subsidiary has UNC Knowledge of
that the other Person to any such Material Contract intends to terminate or
amend such UNC Material Contract in any respect, (iv) UNC or the applicable UNC
Subsidiary party to such UNC Material Contract maintain good business
relationships with the other Person to such UNC Material Contract, and (v) UNC
or the applicable UNC Subsidiary party to such UNC Material Contract has no
reason to believe that the other Person to any such UNC Material Contract does
not intend to continue to conduct business with UNC or such UNC Subsidiary upon
the expiration of the stated term of such UNC Material Contract.

bona fide proposal with respect to the acquisition of all or substantially all

entitled to seek specific performance of this Agreement from applying to and

            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. Conese, 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."

     Gene Conese, 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 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 and UNC,
said: "The acquisition of UNC by GE provides an excellent opportunity for UNC
shareholders, customers, and employees. This link up 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,
1996, will proceed on the same terms and conditions as previously announced.
