Item 2.   Acquisitions and Dispositions of Assets.
          ----------------------------------------

     On December 29, 1995, pursuant to a Purchase Agreement
between Sequa Corporation and certain of its subsidiaries
(collectively, "Sequa") and EL-OP U.S., Inc., Sequa sold
substantially all of the business and operating assets, excluding
billed receivables, of its Kollsman Division ("Kollsman
Division") and its subsidiary, Kollsman Manufacturing Company,
Inc. ("KMC")to Kollsman, Inc. and KMC Systems, Inc., both
Delaware corporations, and Kollsman Export Corporation, a foreign
sales corporation organized under the laws of the United States
Virgin Islands, all of the foregoing being assignees of EL-OP
U.S., Inc. (collectively, "Buyer").  Sequa received $49,612,000
in cash subject to final cash settlement adjustments. 
$20,000,000 of the proceeds was used to repurchase accounts
receivable sold under Sequa's Receivables Purchase Agreement and  
$2,700,000 was used to repay the principal amount outstanding
under Sequa's revolving credit agreement.  The remaining proceeds
were invested in short-term interest-bearing securities.

     The Kollsman Division and KMC together employed
approximately 620 employees in the United States.  The Kollsman
Division designs and manufactures electronic and electro-optical
systems for military use and avionics equipment for commercial,
general aviation and military markets.  KMC produces advanced
diagnostic equipment for medical supply companies.

Item 7.   Financial Statements, Pro Forma Financial Information
          ------------------------------------------------------
          and Exhibits.
          -------------

(b)  Unaudited pro forma financial information of Sequa
     Corporation reflecting the sale of the Kollsman Division and
     KMC.

The unaudited pro forma consolidated financial information gives
effect to the sale of the Kollsman Division and KMC as if the
disposition had occurred, for balance sheet purposes, on
September 30, 1995 and, for income statement purposes, on
January 1 of the earliest period presented.  The Pro Forma
Consolidated Balance Sheet at September 30, 1995 includes a $3.3
million after-tax gain on the sale of the Kollsman Division and
KMC.  This pro forma adjustment has not been made to the Pro
Forma Statements of Consolidated Income as it will not have a
continuing impact on Sequa's results of operations.

The pro forma adjustments are based on presently available
information.  Sequa's final accounting for the disposition of the
Kollsman Division and KMC is still under review by management and
will be finalized prior to the filing of Sequa's Annual Report on
Form 10-K for the year ended December 31, 1995.  The pro forma
gain on the disposition of the Kollsman Division and KMC is based
on the net book value at September 30, 1995 of the assets sold
and a preliminary purchase price which is subject to final cash
settlement adjustments.  Accordingly, Sequa's actual recording of
the disposition may differ from the pro forma financial
information.  The unaudited pro forma financial information has
been included as required by the rules of the Securities and
Exchange Commission and is not necessarily indicative of the
results that would have been reported had the disposition
actually occurred on the dates specified, nor is it indicative of
the results that may be obtained in the future.

                              PURCHASE AGREEMENT

                               November 9, 1995


            The parties to this Purchase Agreement are Sequa
Corporation, a Delaware corporation ("Sequa"), Kollsman
Manufacturing Company, Inc., a Delaware corporation ("KMC"),
Sequa Export Corporation, a foreign sales corporation organized
under the laws of the United States Virgin Islands ("Sequa
Export", and together, jointly and severally, with Sequa and KMC,
"Sellers"), and EL-OP U.S., Inc., a Delaware corporation
("Buyer") and El-Op Electro-Optics Industries, Ltd., an Israeli
corporation which is the guarantor of Buyer's indemnification
obligations and liabilities under Section 9.3 of this Agreement
("Guarantor").

            Sequa's "Kollsman Division" consists of three units
engaged in the following businesses (collectively, "the
Business"):  the military systems unit, a government contract
supplier of electro-optical and electric systems for military
weapons; the avionics products unit, a designer and manufacturer
of aircraft instruments and related test equipment; and KMC and
the business thereof, that produces medical diagnostic
instruments.  Sellers no longer desire to engage in the Business,
and desire to divest themselves of all of the assets related to
the Business (excluding certain assets relating thereto as
provided in this Agreement).  Sequa operates the Business
directly and through KMC and Sequa Export.  Sellers desire to
sell to Buyer the Business, as a going concern, and all of the
assets relating to the Business (excluding certain assets
relating thereto as provided in this Agreement), and Buyer shall
assume certain of the liabilities associated with the Business,
and Buyer desires to purchase the Business, as a going concern,

      Product or Service Warranty for any product manufactured or

      manufactured by the Business);

      that in no event shall such Warranty Costs and Recall Costs
      exceed in the aggregate (i) $1,000,000 for the first twelve

      liability or obligation Sellers may have under Section
      9.2(a) of this Agreement to Buyer with respect to the
      representations and warranties made by Sellers in this
      Agreement, subject, however, to the limitations on
      indemnification and on survival of such representations and

      in Section 6.17 of this Agreement;

                        (xi)  any and all liabilities for royalty
      expense and commissions due pursuant to the provisions of
      the Assigned Agreements with respect to shipments of
      products and/or rendering of services from and after the
      Closing Date; and

                        (xii)  any and all liabilities for
      government recoupment fees due pursuant to the provisions of
      the Assigned Agreements with respect to shipments of
      products and/or rendering of services from and after the
      Closing Date.

                  (b)   Except as specifically provided in Sections
2.2(a)(i) through 2.2(a)(xii), 6.3, 6.22 (to the extent provided
in the Nashua Sublease), 6.23 and 9.3, 9.4 and 9.5 of this
Agreement, Buyer shall not assume or be responsible for any lia-
bilities or obligations of Sellers relating to the Business, the
Assets or otherwise, and Sellers shall continue to be responsible
<PAGE>
for and shall pay, perform and discharge all such liabilities and
obligations.  Without limiting the generality of the preceding
sentence, Buyer shall not assume or be responsible for, and
Sellers shall continue to be responsible for and shall pay,
perform and discharge all Excluded Liabilities.

                  (c)   Sellers hereby agree to pay, perform and
discharge all of the Excluded Liabilities in accordance with the
respective terms and conditions thereof when the same become due
and payable.

            2.3   Adjustment of Base Purchase Price.

                  (a)   Subject to Section 2.3(b) of this Agreement,
if the aggregate amount of Unbilled Receivables and Inventory as
of the close of Business on the Closing Date is greater than
Forty Nine Million One Hundred Sixty Thousand Dollars
($49,160,000), then the Base Purchase Price shall be increased by
an amount equal to that excess.  Subject to Section 2.3(b) of
this Agreement, if the aggregate amount of Unbilled Receivables
and Inventory as of the close of business on the Closing Date is
less than Forty Nine Million One Hundred Sixty Thousand Dollars
($49,160,000), then the Base Purchase Price shall be decreased by
an amount equal to that shortfall.


<PAGE>
                  (b)   Set forth on Schedule 2.3(b)-1 is a list
that Buyer and Sellers agree upon as identifying all items of
military Stock Inventory owned by Sellers as of January 31, 1995,
listing all material items separately (the "Eligible Military
Stock Inventory").  The parties agree that the aggregate amount
of the Eligible Military Stock Inventory was, at January 31,
1995, Twenty-Four Million Three Hundred Nineteen Thousand Dollars
($24,319,000).  For purposes of computing the aggregate amount of
Unbilled Receivables and Inventory in accordance with Section
2.3(a) of this Agreement: (i) only the aggregate amount
(determined in accordance with the Accounting Instructions) of
the balance of the Eligible Military Stock Inventory owned by
Sellers as of the close of business on the Closing Date shall be
taken into account with respect to any military Stock Inventory; 
and (ii) military Stock Inventory, if any, purchased or otherwise
acquired after January 31, 1995, shall not be included in
determining the adjustment to the Base Purchase Price.  For
purposes of Section 2.3(a) of this Agreement, Unbilled
Receivables and Inventory shall be determined as of the close of
business on the Closing Date in accordance with the accounting
instructions set forth on Schedule 2.3(b)-2 (the "Accounting
Instructions").

                  (c)   Within sixty (60) days after the Closing
Date, Buyer shall determine the Unbilled Receivables and
Inventory as of the close of business on the Closing Date and 

<PAGE>
shall deliver to Sellers a statement (the "Final Statement")
setting forth in reasonable detail the amount of Unbilled
Receivables and Inventory as so determined in accordance with the
Accounting Instructions and the resulting adjustments to the Base
Purchase Price pursuant to Sections 2.3(a) and 2.3(b) of this
Agreement.  Sellers shall have forty five (45) days after receipt
of the Final Statement to evaluate the Final Statement.  If
Sellers accept the Final Statement or do not give Buyer notice
within such forty five (45) day period that it disputes the Final
Statement or any portion thereof, then within seven (7) days
after the expiration of such forty five (45) day period, Buyer
shall pay to Sellers, or Sellers shall pay to Buyer, as the case
may be, the net amount due as a result of any adjustment (or, if
there is any dispute, the undisputed amount).  If, however,
within that forty five (45) day period Sellers give notice to
Buyer that they dispute Buyer's determinations as set forth in
the Final Statement, the parties shall confer with regard to the
matter and an appropriate adjustment and payment shall be made as
agreed upon by the parties; if they are unable to resolve the
matter within an additional thirty (30) days after the giving of
such notice by Sellers, a firm of independent certified public
accountants of recognized standing (the "Accountants"), whose
decision on the matter shall be final and binding on the parties,
shall be designated by agreement between Sellers and Buyer to
resolve such dispute (if they fail to agree within such thirty
(30) additional days, the Accountants shall be Price Waterhouse) 

<PAGE>
and payment based on the Accountants' decision as to the Final
Statement shall be made promptly after notification of the
decision.  The fees and expenses of the Accountants shall be
borne 50% by Buyer and 50% by Sellers.

            2.4   Purchase Price Allocation.  The purchase price
shall be allocated among the Assets in accordance with Schedule
2.4 as agreed upon by the parties.  The parties shall conform to
that allocation for all pertinent tax purposes, and each of the
parties shall file with the Internal Revenue Service ("IRS") a
Form 8594 on a basis consistent with that allocation.

      3.    Closing.

            3.1   Date of Closing.  The closing (the "Closing")
under this Agreement shall take place at the offices of Proskauer
Rose Goetz & Mendelsohn LLP, 1585 Broadway, New York, New York
(or at such other place as the parties may agree upon in writing)
upon at least five Business Days prior notice given by Buyer to
Sellers within five Business Days after the last of the
conditions specified in Sections 7.1 and 7.2 of this Agreement
has been fulfilled (or waived), but in no event whatsoever later
than December 10, 1995.  The date on which the Closing is held is
referred to in this Agreement as the "Closing Date."  At the
Closing, the parties shall execute and deliver the documents
referred to in Section 8 of this Agreement.
<PAGE>

            3.2   Outside Date for Closing.  If the Closing has not
occurred by December 10, 1995, Sellers or Buyer may terminate
this Agreement by notice to the other.  Upon termination pursuant
to this Section 3.2 neither of the parties shall have any
liability of any kind arising out of this Agreement other than
for any liability resulting from its breach of this Agreement
prior to termination.  If the Closing is postponed pursuant to
Section 11 of this Agreement, and this Agreement is not otherwise
terminated in accordance with the provisions of Section 11, the
outside date referred to in this Section shall be extended by the
period of the postponement as provided in Section 11.

      4.    Representations and Warranties by Sellers. Each Seller
represents and warrants to Buyer as follows:

            4.1   Organization and Authority.  Each Seller is a
corporation duly organized, validly existing and in good standing
under the law of the jurisdiction of its incorporation and has
the full corporate power and authority to enter into and to
perform this Agreement and to own lease and operate its
properties as it now does and to carry on its business as it is
presently being conducted.  Each Seller is duly qualified and in
good standing as a foreign corporation in all jurisdictions where
the failure to so qualify or be in good standing would have a
material adverse effect on the Business and/or the Assets.  A 

<PAGE>
list of such jurisdictions where any Seller is qualified as a
foreign corporation is set forth on Schedule 4.1.

            4.2   Authorization of Agreement.  The execution,
delivery and performance of this Agreement by each Seller have
been duly authorized by all necessary corporate action of such
Seller (including approval of its board of directors and/or its
shareholders, if required), and this Agreement constitutes a
valid and binding obligation enforceable against such Seller in
accordance with its terms, except as may be limited by
bankruptcy, insolvency or other similar laws affecting the
enforcement of creditors' rights in general and subject to
general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at
law).  Each Seller shall furnish to Buyer any documents
reasonably requested by Buyer or Buyer's title insurance company
and/or such other title insurer or title insurers (whether on a
co-insurance or reinsurance basis) as may be satisfactory to
Buyer which evidence the capacity and authorization of each of
such Seller (and the signatories acting on behalf of it) to
consummate the transactions contemplated hereby.

            4.3   No Conflicts.  Subject to receipt of the consents
and approvals referred to on Schedule 4.3, the execution,
delivery and performance of this Agreement by Sellers will not
(i) conflict with their respective certificate of incorporation 

<PAGE>
or by-laws and will not conflict with, or result in a breach or
termination of, or constitute a default under, any lease, agree-
ment, commitment or other instrument, or any order, judgment or
decree, by which any Seller is bound, or to which any of the
Assets is subject; (ii) constitute a violation by any Seller of
any law or regulation applicable to it; (iii) result in the
creation of any lien, claim, charge, security interest or
encumbrance ("Lien") upon any of the Assets; or (iv) adversely
affect the operation of the Business in any respect.  Except as
set forth on Schedule 4.3 and for the consents referred to in
Sections 6.1 and 6.2 of this Agreement or otherwise provided by
the terms of any of the Assigned Agreements but only insofar as
such consents apply to the assignment of that particular Assigned
Agreement, no consent, approval or authorization of, or desig-
nation, declaration or filing with, any governmental authority or
any person or entity is required on the part of any Seller in
connection with the execution, delivery and performance of this
Agreement.

            4.4   Title to Assets.  Except as set forth on Schedule
4.4 and except for the lien, if any, of current Taxes not yet due
and payable, each Seller has, and at the Closing Buyer will
receive, valid title, free and clear of any Liens, to all of the
Assets to be conveyed by such Seller pursuant to this Agreement. 
Nothing in this Section 4.4 shall be deemed to constitute either
an express or implied representation or warranty with respect to 
<PAGE>

any restrictions which the terms and conditions of any of the
Assigned Agreements impose solely on that Assigned Agreement and
no other Assets.

            4.5   Condition of Personal Property.  Except as set
forth on Schedule 4.5, since May 30, 1995, all material equipment
and other material tangible assets used or held for use in the
Business have, in all material respects, been maintained in the
ordinary course without any deferral of maintenance.  Except as
set forth on Schedule 4.5, since May 30, 1995, no material amount
of such equipment or other tangible personal property (other than
Inventory) has been removed from any Seller's premises.  To the
best of Sellers' knowledge, Schedule 1.1(b) contains a true and
complete list of all material equipment and such other tangible
personal property (other than Inventory) used or held for use in
the Business as of September 30, 1995.

            4.6   Certain Subsidiaries.  Sequa is the record and
beneficial owner of all of the outstanding shares of capital
stock of KMC and Sequa Export.  The copies of the certificate of
incorporation and by-laws of KMC and Sequa Export that have been
delivered to Buyer are complete and correct and have not been
amended.  Sellers conduct the Business directly through Sequa's
Kollsman Division, KMC and Sequa Export and through no other
entity.  There are no existing arrangements that require or 

<PAGE>
permit any shares of KMC or Sequa Export to be voted by or at the
discretion of anyone other than Sequa. 

            4.7   Real Property Interests.

                  (a)   Except for the Title Exceptions listed on
Schedule 4.7(a)-1 (the "Permitted Exceptions"), Sequa has good
and marketable fee title to the Land and Improvements and good
and marketable leasehold title to the leasehold estates created
by the Office Leases and the Nashua Lease, subject to the terms
and conditions of those leases.  No Seller has made any
assignment, pledge or mortgage of, or granted any security
interest in, any portion of the Real Property, or its leasehold
interests in the Office Leases and the Nashua Lease.  For
purposes of this Agreement, the term "Title Exceptions" means any
defects in, exceptions to, or conditions, liens, mortgages,
encumbrances or other matters relating to title to any portion of
the Real Property, whether evidenced by written instrument or
otherwise evidenced; any encroachments upon any portion of the
Real Property by improvements situated on other lands; any
encroachments by the Improvements (including the improvements
demised by the Office Leases and the Nashua Lease) onto any lands
adjoining any portion of the Real Property; any boundary disputes
regarding the boundaries of the Real Property; and the terms,
provisions and conditions contained in any instruments evidencing
or referring to any such defects, exceptions, conditions, liens, 

<PAGE>
mortgages, encumbrances, encroachments, boundary disputes or
other matters excepting any of the foregoing that do not
individually or in the aggregate materially detract from or
interfere with the use of the Land, Real Property or Improvements
or the operation of the Business which, for purposes of this
Agreement, shall be deemed to be Permitted Exceptions.  The Land,
the Improvements, the Office Leases and the Nashua Lease each
comprise substantially all the real property interests of that
type used in or held for use in connection with the operation of
the Business.

                  (b)   Except as otherwise disclosed in Schedule
4.7(b), no default on the part of any Seller exists, and, to the
best of Sellers' knowledge, no non-monetary default exists, nor
has any written notice thereof been received under the terms of
any of the Real Property Documents which has not been remedied
under the terms of such Real Property Document.  To Sellers'
knowledge, no circumstances or state of affairs presently exists
which with notice, lapse of time, or both could reasonably be
anticipated to result in the existence of a default on the part
of any Seller under the terms of any of the Real Property
Documents, or which could reasonably be anticipated to give any
other party to any of the Real Property Documents the right to
terminate such Real Property Document or pursue any other
recourse or remedy against any Seller or the Real Property or the
premises demised under the Office Leases or the Nashua Lease 
<PAGE>

provided for at law or in equity or under the terms of such Real
Property Document.

                  (c)   Except as provided under the terms of the
Office Leases or the Nashua Lease, no person, firm or entity has
any possessory interest in, or any other rights with regard to
the use of, any portion of the Real Property (whether pursuant to
lease, sublease, rental, license, concession, management or other
agreement, written or oral, now or hereafter in effect).  No
Seller has granted any rights to acquire or to lease any portion
of the Real Property, including, without limitation, any renewals
or extension options, or any part thereof or otherwise obtain any
interest therein.  No Seller has granted any rights of first
refusal, rights of reverter or rights of first offer that are
outstanding relating to the Real Property or any interest
therein.

                  (d)   True, complete and correct copies of all the
Real Property Documents and of all written notices of default (if
any) received with respect to the Real Property Documents and
that remain pending have been delivered to Buyer and have been
initialled by the appropriate Seller and Buyer.

                  (e)   Sellers have no interest as a landlord in
any lease or other agreement for the use and occupancy of all or

<PAGE>
any portion of the Land, Improvements or the premises demised
under the Office Leases or the Nashua Lease.

                  (f)   There is no indebtedness or monetary
obligation secured by or in any manner constituting a lien,
security interest or other monetary encumbrance on the Real
Property.

                  (g)   The Real Property, and the construction, use
and operation thereof, are, to Sellers' knowledge, in material
compliance with all applicable local, state or federal laws,
municipal ordinances or regulations, orders, rules or
requirements of any federal, state, municipal department or other
governmental authority having jurisdiction against or affecting
the Real Property or the construction, ownership, maintenance,
operation, use or improvement thereof (including, without
limitation, applicable zoning, building, health and environmental
laws, ordinances, regulations, orders, rules or requirements, and
laws, ordinances, regulations, orders, rules or requirements
applicable to the establishment and maintenance of working
conditions for labor) ("Legal Requirements"), and no Seller has
received written notice (which remains uncured) of, nor has any
Seller any knowledge of, (i) any uncured violation of any
applicable Legal Requirements whether or not officially noted or
issued, or (ii) any condition relating to the Real Property which
could reasonably be expected to constitute a material violation

<PAGE>
of any applicable Legal Requirements.  Sellers shall give Buyer
notice of any violation of any Legal Requirement of which any
Seller obtains written notice or acquires knowledge between the
date of this Agreement and the Closing Date.

                  (h)   There is no pending or, to the best of
Sellers' knowledge, threatened annexation or condemnation
proceeding involving all or a portion of the Real Property.

                  (i)   Except as disclosed on Schedule 4.7(i)-1,
there are no, and for the past three years have not been any,
proceedings seeking a reduction in real estate taxes imposed upon
any portion of the Real Property (other than the premises demised
under the Office Leases).  There is no pending or, to Sellers'
knowledge, threatened imposition of any special or other
assessments affecting any portion of the Real Property or any
penalties or interest due with respect to the real estate taxes
assessed against all or any portion of the Real Property that are
payable by the owner or, in the case of Real Property leased to
any Seller, the tenant thereof or that could result in a Lien
thereon.  True and complete copies of all tax bills with respect
to each portion of the Real Property (other than with respect to
the land and improvements demised under the Office Leases)
payable for the last three years have been initialled by Sellers
and Buyer and have been annexed to this Agreement as Schedule
4.7(i)-2.

<PAGE>
            4.8   Financial Statements; Other Financial Information.

                  (a)   Schedule 4.8 contains (x) an unaudited
balance sheet of the Business as of December 31, 1994, together
with the related statements of operations for the twelve month
period then ended, and (y) an unaudited balance sheet of the
Business as of September 30, 1995 (the "Balance Sheet"), together
with the related statement of operations for the nine month
period then ended.  Except as described in Schedule 4.8, all of
the financial statements contained in Schedule 4.8 are in
accordance with the books and records of Sellers, fairly present,
in all material respects, the financial position and the results
of operations of the Business as of the dates and for the periods
indicated (subject to normal year end adjustments with respect to
the Balance Sheet and the related statements for the nine months
then ended none of which are material in any respect), which
statements were provided to Sequa in accordance with its
divisional reporting practices, which are subject to Sequa's
further adjustments for the purposes of Sequa's financial
reporting, which adjustments may be material.

                  (b)   All of the accounts receivable of Sellers
arising out of the Business and all of the Unbilled Receivables
reflected in the Balance Sheet and/or Schedule M and Schedule CY-
2 arose from bona fide transactions in the ordinary course of
business.  To the best of Sellers' knowledge, Schedule CY-2 

<PAGE>
contains a true and correct list of all Unbilled Receivables as
of September 30, 1995.  Nothing contained in this Agreement shall
constitute a representation or warranty of collectibility of any
Unbilled Receivable.

            4.9   Absence of Certain Changes.  Since January 31,
1995, Sellers have operated the Business in the ordinary course
and consistent with past practice, and, except as set forth on
Schedule 4.9:

                  (a)   there has been no material adverse change in
the condition (financial or otherwise) or operations of the
Business or the Assets;

                  (b)   no Seller (as it relates to the Business)
has (i) entered into any transaction that is material to the
Business other than in the ordinary course, (ii) made any
material change in its accounting methods or principles or (iii)
incurred any indebtedness for borrowed money with respect to the
Business or the Assets; or

                  (c)   no Seller has granted or agreed to grant any
general increase in any rate or rates of salaries, compensation
or benefits to the employees of the Business or any specific
increase in the salary, compensation or benefits to (x) any
employee whose total salary and compensation after such increase

<PAGE>
would be at an annual rate in excess of $90,000, other than in
the ordinary course of business, or (y) any other employee
outside of the ordinary course of business;

                  (d)   no Seller has established any new Benefit
Plan, amended or modified any existing Benefit Plan or incurred
any obligation or liability under any Benefit Plan materially
different in nature or amount from obligations or liabilities
incurred during similar periods in prior years; 

                  (e)   there presently are no Claims Receivable or
Notes Receivable other than as indicated on Schedule 4.9(e) as
may be updated through the close of business on the Closing Date;
and

                  (f)   there have been no purchases or other
additions of military Stock Inventory.

            4.10  Litigation; Compliance with Laws.  Except as set
forth on Schedule 4.10, there is no claim, litigation, proceeding
or governmental investigation pending or, to the best of the
knowledge of Sellers, threatened, nor is there any order,
injunction or decree outstanding, against any Seller relating to
the Business and/or the Assets which could reasonably be
determined to have a material adverse effect on the Business
and/or the Assets.  To the best of Sellers' knowledge, no Seller

<PAGE>
is in violation of any law, regulation or ordinance or any other
requirement of any governmental body or court with respect to the
operation of the Business and/or the Assets the consequence of
which could be reasonably expected to have a material adverse
effect on the Business and/or the Assets, and no written notice
has been received by any Seller alleging any such violation which
has not since been remedied.  Except as set forth on Schedule
4.10, within the past twelve (12) months, no Seller has entered
into any written agreement with (and no such written agreement
exists), had any material dispute with respect to any law,
regulation or ordinance, or, to Sellers' knowledge, been the
subject of any investigation by, any governmental authority or
community group that could reasonably be expected to adversely
affect the operation of the Business and/or the Assets.

            4.11  List of Agreements, Etc.  Schedule 4.11 contains,
with respect to the Business and the Assets, a complete list of: 
(a) all Purchase Contracts, other than those that were entered
into in the ordinary course of business and that involve an
expenditure by Sellers of less than $75,000 for any one
commitment or two or more related commitments; (b) all Personal
Property Leases; (c) all Teaming Agreements; (d) all Customer
Agreements (indicating which Customer Agreements relate to KMC);
(e) all Sales Contracts; (f) all Representative Agreements; (g)
all Licensing Agreements; and (h) all other agreements,
commitments and understandings (written or oral) that require

<PAGE>
payment by or to any Seller of more than $50,000 individually or
that are otherwise material to the Business and/or the Assets. 
True and complete copies of all of the leases, commitments and
other agreements referred to on Schedules 4.11 and 4.12-4 have
been delivered to Buyer.

            4.12  Employees.  Attached hereto as Schedule 4.12-1 is
a complete and correct list of the employees of Sequa and KMC
employed solely in the Business ("Employees"), which list also
includes each such employee's current salary, the date and amount
of the last salary increase and the amount of any other
compensation, including bonus, paid to such employee during the
previous twelve month period or currently due, and such
employee's position (specifying whether such position is with KMC
or Sequa, place of employment, date of birth and date of
employment).  None of such compensation reflects settlements of
any claims other than salary negotiations in the ordinary course
of business consistent with past practice.  Except as set forth
on Schedule 4.12-2, none of the Employees has, since April 10,
1995, given written notice to Sequa or KMC of either a desire to
terminate his or her employment or of any intention to terminate
his or her employment upon a sale of the Business.  Except as set
forth on Schedule 4.12-3, since April 10, 1995, Sequa has not
directed management of the Business to refrain from terminating
any Employee other than in the ordinary course of business.  No
Employees are represented by any labor or trade union and, to the

<PAGE>
best of Sellers' knowledge, no movement to designate a collective
bargaining unit to represent any of the Employees exists or, to
Sellers' knowledge, is threatened.  Except as set forth on
Schedule 4.12-4, the transactions contemplated by this Agreement
will not trigger any extraordinary payment of any kind to any
Employees other than an obligation to make severance payments
solely pursuant to the Benefit Plans or otherwise as provided by
the Benefit Plans.

            4.13  Status of Agreements.  All leases, commitments and
other agreements of Sellers to be assumed by Buyer were entered
into in connection with and in the ordinary course of the
Business.  Each of the Assigned Agreements is presently in full
force and effect in accordance with its terms and no written
notice has been received by any Seller alleging any default under
any of the Assigned Agreements.  To the best of Sellers'
knowledge, no Seller is in material default and, to the knowledge

limited to, laws relating to emissions, discharges, releases or
threatened releases of Materials of Environmental Concern, or

activities, events or incidents, including, but not limited to,
the release, emission, discharge or disposal of any Material of

liability for any claim or violation arises under Environmental
Laws that any Seller has (or may have) retained or assumed either
contractually or by operation of law relating to the Business
and/or the Assets.

National Priorities List pursuant to the Comprehensive
Environmental Response, Compensation and Liability Act
("CERCLA"), 42 U.S.C. . 9601 et seq., or any similar inventory of

<PAGE>
respect to the real property comprising the Assets or the conduct
of the Business.

                  (e)   To the best of Sellers' knowledge, except as

other authorizations necessary for the conduct of the Business
and the possession, ownership and use of the Assets by Sellers. 
All Permits are valid and in full force and effect.

            4.20  Taxes.  No Seller is a "foreign person" as that
term is defined in Section 1445(f)(3) of the Code.

            4.21  Inventory.  All items of Inventory are being
purchased on an "AS IS/WHERE IS" and "WITH ALL FAULTS" basis;
except that since May 30, 1995, Sellers have continued to

<PAGE>
maintain the Inventory in the ordinary course of business
consistent with past practice.  Schedules AB and CR are, to the
best of Sellers' knowledge, true and complete lists of the
Contract Inventory and the Stock Inventory, respectively, as of
September 30, 1995.

            4.22  Sufficient Assets.  The Assets include all of the
assets reflected on the Balance Sheet (except Excluded Assets and

            4.24  Products; Customers; Suppliers.  Schedule 4.24

Business measured by purchases and, to the best of Sellers'

<PAGE>
knowledge, all material sole source suppliers; and (b) the ten
largest customers of the Business measured by sales.  Except as
set forth on Schedule 4.24, no Seller is engaged in any pending
material dispute with any of those customers or suppliers and no
such customer or supplier has since January 1, 1995 notified any
Seller in writing that it is considering termination, non-renewal
or any adverse modification of its agreement or arrangement with
respect to the Business.

            4.25  Product Warranties.  Set forth as Schedule 4.25 is

Warranties made by Sellers with respect to each category of
products and services sold and to be sold as of the date hereof

as of the date hereof.  Except by operation of law (to the extent
not effectively excluded or disclaimed) and as set forth in
Schedule 4.25, to the best of Sellers' knowledge, no Seller has
given any other written warranty concerning the nature,
merchantability, fitness for a particular purpose or expected
performance in connection with the products and services shipped

Schedule 4.25 and since January 1, 1990, no products or services
shipped and/or sold or contracted to be shipped and/or sold by
the Business on or prior to the Closing Date have at any time
been subject to any voluntary or mandated governmental recall

<PAGE>
(whether federal, state, local or foreign), and, to the best of
Sellers' knowledge,  there is no presently existing circumstance
that could reasonably be expected to constitute a valid basis for
any such recall.

            4.26  FCPA Compliance.  The accounting procedures and
control systems of Sellers relating to the Business are, to
Sellers' knowledge, sufficient to comply in all material respects
with the requirements of the Foreign Corrupt Practices Act, 15
U.S.C. .. 78m, 78dd-1, 78dd-2, 78ff (1986), as amended.

            4.27  Certain Affiliates.  All Affiliates of Sellers
that have a name containing the word "Kollsman" or the
abbreviations "KMC", "KIC" or "KSM" or that do business under any
such name, are listed on Schedule 4.27.  At the Closing, and from
time to time thereafter, Sellers shall take such action, or cause
any such Affiliate to take such action, as Buyer may reasonably
request in order to change the name of any Seller or any such
Affiliate to a name not containing the word "Kollsman" or the

entirely of Sequa's minority ownership interest in KSAL.

            nME  No Misrepresentation.  No representation or
warranty by any Seller in this Agreement (including the Schedules
and Exhibits to this Agreement) and no statement made or
contained in any certificate or instrument delivered or to be
delivered to Buyer pursuant to this Agreement contains or will
contain any untrue statement of a material fact or omits or will
omit to state a material fact necessary to make the statements
contained in this Agreement (including the Schedules and Exhibits
to this Agreement) not misleading at the time given or on the
Closing Date.  Sellers make no representation or warranty with
respect to Schedules 2.3(b)-1, 2.3(b)-2, 2.4, 5.5, 6.8, 6.9, 6.18

applicable to Buyer.

            5.4   Litigation.  There is no claim, litigation,

                  (b)  if the parties are unable to obtain a
Required Consent, then, (i) with respect to the contract, lease,
license, permit, approval or other item with respect to which
such Required Consent is not obtained, this Agreement shall not
constitute or be deemed to be an assignment or an agreement to
assign such item if an attempted assignment without such Required
Consent would constitute a breach of or default under such item
or create in any party thereto the right or power to cancel or
terminate such item, and (ii) Buyer shall be entitled to
terminate this Agreement in accordance with Section 10.1(b) of
this Agreement if all Required Consents have not been obtained at
least five (5) days prior to the Closing Date; and 

                  (c)  neither Sellers nor Buyers will be obligated
to incur out-of-pocket expenses (except for reasonable travel
expenses) or commence litigation in order to obtain any Required
Consent pursuant to this Section 6.8.

            6.10  Expenses.  Unless otherwise provided in this
Agreement, each party shall bear its own expenses incurred in
connection with the negotiation and preparation of this Agreement
and in connection with all obligations required to be performed
by it under this Agreement.

            6.11  Access to Information Prior to and After Closing.

                  (a) Prior to the Closing, Buyer and its
representatives may make such reasonable investigation of the
assets and business of the Business as it may desire, and Sellers
shall give to Buyer and to its counsel, accountants and other
representatives reasonable access during normal business hours
throughout the period prior to the Closing to all of the assets,
books, commitments, agreements, records, employees, customers, 

<PAGE>
suppliers and files of Sellers relating to the Business and/or
the Assets, and Sellers shall furnish to Buyer during that period
all documents and copies of documents and information concerning
the business and affairs of the Business and/or the Assets as
Buyer reasonably may request.  All information furnished to Buyer
by Sellers under this Section 6.11 shall be subject to that
certain Confidentiality Agreement, dated November 30, 1994
between Sequa and Buyer.

                  (b)  For a period of seven (7) years following the
Closing, the parties will retain all business records reflecting
the assets and liabilities of or relating to the Business in
existence as of the Closing, including, without limitation, those
related to the Excluded Assets and the Excluded Liabilities (the
"Business Records").  During such period, the parties will afford
authorized representatives of one another free and full access,
subject to applicable law and governmental clearance, of all of
the Business Records at reasonable times and during normal
business hours at the principal business office of the Business
or of the Sellers or any of them, as appropriate, or at such
other location or locations at which the Business Records may be
stored or maintained from time to time, and will permit such
representatives to make abstracts from, or copies of, any of the
Business Records, or to obtain temporary possession of any
thereof as may be reasonably required by the requesting party at
such party's sole cost and expense.  If any party proposes to

<PAGE>
destroy any Business Records after the expiration of seven (7)
years following the Closing, it shall provide written notice of
such intent to the other parties.  If within 30 days after
receipt of such notice, the other party notifies the first party
of its desire to retain the Business Records, the responding
party shall be entitled to remove and retain (at its own cost and
expense) the Business Records that the first party proposes to
destroy, within 90 days after the sending of the response.

            6.12  Additional Information.  Sellers shall promptly
deliver to Buyer copies of all financial statements and reports
which are reasonably requested by Buyer and, in either case,
without representation or warranty as to the truth or accuracy of
the same relating to the Business that may be prepared by it
during the period from the date of this Agreement to the Closing
Date.  Sellers shall furnish to Buyer any other information
concerning the financial and operating condition of the Business
and/or the Assets that Buyer from time to time may reasonably
request.

            6.13  Business Disclaimer.

                  (a)   Except for representations and warranties
expressly set forth in this Agreement, the Schedules and the
documents and instruments delivered pursuant to this Agreement at
Closing, Buyer UNDERSTANDS AND AGREES THAT NONE OF SELLERS OR

<PAGE>
ANYONE ACTING ON THEIR BEHALF, MAKES ANY EXPRESS OR IMPLIED
REPRESENTATIONS OR WARRANTIES (EXCEPT AS SET FORTH HEREIN) WITH
RESPECT TO THE FINANCIAL CONDITION, ASSETS, PROPERTIES OR
BUSINESS (CURRENT, FIXED, PERSONAL, REAL TANGIBLE AND INTANGIBLE)
REFERRED TO HEREIN, INCLUDING BUT NOT LIMITED TO, CAPACITY,
SUITABILITY, UTILITY, SALABILITY, AVAILABILITY, PROFITABILITY,
COLLECTIBILITY AND OPERATION.

                  (b)   Buyer will purchase the Assets and will
enter into the transactions contemplated by this Agreement with
the understanding, acknowledgement and agreement by Buyer that no
representations or warranties, express or implied, are made with
respect to future prospects (financial or otherwise) of the
Business.

                  (c)   Except as provided in this Agreement and the
Schedules hereto, Sellers expressly disclaim (and Buyer accepts
such disclaimer) any and all obligation or liability for
representations and warranties, express or implied, contained in,
or for omissions from, any written or oral communications,
including, without limitation, due diligence materials heretofore
transmitted to or in any matter obtained by, Buyer in the course
of its investigation of the Business.  Buyer represents and
warrants that, in Buyer's determination to buy the Assets and to
consummate the transactions contemplated by this Agreement, Buyer
has not relied on any information previously delivered or

<PAGE>
otherwise acquired, learned or obtained, but rather is entering
this transaction solely upon the basis of the express
representations and warranties contained in this Agreement.

                  (d)   Notwithstanding the foregoing, Sellers
hereby represent and warrant to Buyer that those written
materials that are described on Schedule 6.13, are true,  correct
and complete copies of the documents and materials that they
purport to be, provided that, no representation or warranty is
made with regard to the accuracy or completeness of the
statements made therein.

            6.14  Covenant Against Competition, Solicitation and
Disclosure.  To accord to Buyer the full value of its purchase,
Sellers and Buyer shall enter into an agreement in the form of
Exhibit 6.14 (the "Non-Competition Agreement"), which provides
that none of Sellers or their respective Affiliates shall subject
to certain limitations and exceptions contained in the Non-
Competition Agreement (a) for a period of five (5) years after
the Closing Date, directly or indirectly, engage or become
interested in (as owner, stockholder, partner or otherwise) any
business or entity that engages anywhere in the world in any
business competitive with the Business, (b) at any time disclose
to anyone, or use in competition with the Business, any
information with respect to any confidential or secret aspect of
the operations of the Business and that of the customers of the

<PAGE>
Business, except as required by law or as relates to the Excluded
Assets and/or Excluded Liabilities, or (c) for a period of five
(5) years after the Closing Date, solicit for employment or hire
any employee of the Business on the date of this Agreement or on
the Closing Date.  Each Seller acknowledges that the remedy at
law for breach of the provisions of this Section 6.14, or the
Non-Competition Agreement will be inadequate and that, in
addition to any other remedy Buyer may have, it will be entitled,
under the terms of this Agreement and the Non-Competition
Agreement, to an injunction restraining any such breach or
threatened breach, without any bond or other security being
required (subject to money damages in the event Buyer wrongfully
obtains injunctive relief without any such security).  If any
court construes the covenant in this Section 6.14 or the
corresponding covenant in the Non-Competition Agreement, or any
part thereof, to be unenforceable because of its duration or the
area covered thereby, the court shall have the power to reduce
the duration or area to the extent necessary so that the
provision is enforceable, and such provision, as reduced, shall
then be enforceable.

            6.15  Accounts Receivable.

                  (a)   If any Seller shall at any time after the
Closing receive any payments with respect to any Assets,
including Unbilled Receivables, it shall immediately forward such

<PAGE>
payments to Buyer.  If Buyer shall at any time after the Closing
receive any payments with respect to any Excluded Assets,
including Billed Receivables, retained by Sellers pursuant to the
provisions of Section 1.2 of this Agreement, it shall immediately
forward such payments to Sequa.  Buyer and Sellers will exchange
reports of daily receipts to assure proper identification and
allocation of receipts in respect of Billed Receivables and
Unbilled Receivables.

                  (b)   For the purpose of complying with paragraph
(a) above, any payment received by Buyer or Sellers with respect
to an account receivable after the Closing that is specifically
identified by a payor as relating to a specified account
receivable shall be applied to that receivable.  If no account
receivable is identified by the payor, the recipient shall inform
the other party of its receipt of the payment promptly after its
receipt thereof and, simultaneously therewith, request in writing
of the payor that it specifically identify in writing the account
receivable in respect of which the payment was made.  If the
payor does so specify an account receivable, the payment shall be
applied to that receivable.  If the payor fails to specify an
account receivable within forty-five (45) days after the making
of such a request, the payment received by Buyer or Sellers shall
first be applied to the earliest account receivable due from that
debtor.


<PAGE>
            6.16  Other Action.  Each of the parties to this
Agreement shall use its commercially reasonable efforts to cause
the Closing to be held at the earliest practicable date and, in
that connection, to cause the fulfillment at the earliest
practicable date of all of the respective conditions to the
obligations of the parties to consummate the sale and purchase
under this Agreement.

            6.17  Employee Matters.

                  (a)   Except as otherwise provided below, Buyer
shall, as of the close of business on the Closing Date, offer
employment to all Employees who are actively at work in the
Business or are on temporary disability, worker's compensation,
leave of absence, vacation or sick leave on the Closing Date. 
The terms and conditions to be offered by Buyer to each of such
Employees shall be substantially equivalent to the terms and
conditions being paid to each such Employee by Sellers on the
Closing Date.  The employment by Buyer of any Employee who
accepts the terms and conditions of employment offered by Buyer
will commence as of the close of business on the Closing Date. 
For purposes of this Agreement, Employees who accept employment
with Buyer as of the close of business on the Closing Date are
hereinafter referred to as "Post-Closing Employees."  With
respect to any Post-Closing Employee who, during the period
continuing for four (4) months following the Closing Date, Buyer

<PAGE>
either terminates (other than for cause) or does not continue to
offer terms and conditions of employment that are substantially
equivalent to the terms and conditions of employment being paid
to such Post-Closing Employee by Sellers on the Closing Date,
Buyer shall reimburse Sellers for any severance payments and
related payments required to be made by Sellers in accordance
with the severance plan described on Schedule 6.17 to such Post-
Closing Employee.  Sellers agree to cooperate with Buyer by
permitting Buyer throughout the period prior to the Closing Date
to meet with Employees at such reasonable times as shall be
approved by a representative of Sellers and to distribute to such
Employees such forms and other documents relating to employment
by Buyer after the Closing Date as Buyer shall reasonably
request.  Although Buyer has no present intention of terminating
the employment of any Post-Closing Employees or reducing the
compensation of any such Post-Closing Employee, other than for
"cause" or by reason of a change in circumstances affecting or
relating to the Business, nothing in this Section 6.17 shall be
deemed to require Buyer to retain any of the Post-Closing
Employees for any fixed period of time or at any particular
compensation rate or in any particular position or prevent Buyer
from being able to continue, modify or establish such benefits
and conditions of employment as it shall determine in its sole
discretion.  Nothing herein contained shall grant to any person
any right of employment, nor shall anything herein contained
constitute an agreement to employ any person.
<PAGE>

                  (b)   Buyer will not assume any of the Benefit
Plans, or any rights, duties, obligations or liabilities
thereunder, nor shall it become a successor employer or be
responsible in any way for Sellers' or a Common Control Entity's
participation in or obligations or responsibilities with respect
to any Benefit Plan, nor shall it be obligated by this Agreement
to make any provision with respect to employee benefits after the
Closing Date.  Employment of all Employees and coverage of all
such Employees, their dependents and beneficiaries under any
Benefit Plans, shall in all respects terminate as of the close of
business on the Closing Date. 

                  (c)   Each Seller shall pay to each Employee, as
applicable, (i) the value of any accrued but unused vacation
entitlements and all other accrued benefits of such employee as
of the Closing Date as soon as practicable after the Closing Date
and in the case of the pension plan, and 401(k) plan, in
accordance with the provisions of such plans, and (ii) a pro rata
portion of the amount which would be payable to such Employee
under any incentive or bonus plan described on Schedule 4.17 for
the period from January 1, 1995 up to and including the Closing
Date, promptly after the adjustments referred to in Section 2.3
of this Agreement have been finally determined and made.


<PAGE>
            6.18  Further Assurances.  At any time and from time to
time after the Closing, each of the parties shall, without
further consideration, execute and deliver to the other party
such additional instruments of transfer and assumption, and shall
take such other action as the other may request to carry out the
transactions contemplated by this Agreement and effect an orderly
transition including, without limitation, those matters referred
to in Schedule 6.18.

            6.19  Miscellaneous Real Estate Documents.  Schedule
6.19 contains:  (i) to the extent available, a copy of any
Seller's existing title insurance policy for each parcel of the
Real Property, and (ii) true, correct and complete copies of all
of the Real Property Documents.  

            6.20  Payment of Costs and Expenses.  Each Seller shall
pay all fees and expenses of its legal counsel and other
advisors.  Buyer shall pay for the cost of the surveys of the
Land and of its due diligence investigation of the Real Property,
the cost of any title insurance which it may elect to obtain and
all fees and expenses of its legal counsel and other advisors.

            6.21  Insurance Coverage.  With respect to liability for
bodily injury, death and property damage occurring after the
close of business on the Closing Date arising out of or in
connection with products manufactured or services performed and

<PAGE>
sold or shipped prior to close of business on the Closing Date,
Buyer shall obtain and maintain for not less than 10 years after
the Closing Date, to the extent available, the insurance
coverages listed on Schedule 6.21 which insurance will include a
waiver of subrogation.  The cost of such coverages shall be borne
as between Sellers and Buyers on a 50/50 basis.  Buyer shall
(i) furnish Sellers, from time to time upon request, with copies
of the insurance policies required to be maintained pursuant to
this Section 6.21, together with all amendments thereto,
(ii) require the carriers to furnish to Sellers, copies of any
notice of expiration or termination or modification or similar
notice with respect to any such insurance policy. 
Notwithstanding anything to the contrary in this Agreement, Buyer
shall have no obligation with respect to liability for bodily
injury, death and property damage occurring after the close of
business on the Closing Date arising out of or in connection with
products manufactured or services performed and sold or shipped
on or prior to the close of business on the Closing Date, other
than to comply with the provisions of this Section 6.21.

            6.22  Nashua Lease.  At the Closing, the appropriate
Seller shall sub-lease the premises demised under the Nashua
Lease on the terms and conditions set forth in a sub-lease in
substantially the form annexed hereto as Exhibit 6.22 (the
"Nashua Sub-lease")


<PAGE>
            6.23  Warranty Costs and Recall Costs Reimbursement.

                  (a)   Buyer shall maintain a detailed record and
account, including unit serial numbers, of Warranty Costs and
Recall Costs incurred during each of the first two 12 month
periods following the Closing Date with respect to any product
manufactured or service performed that is sold and shipped on or
before the close of business on the Closing Date and prepare a
quarterly report of such Warranty Costs and Recall Costs and send
a copy thereof to Sellers.  Sellers or their representatives
shall have reasonable access during normal business hours to
inspect Buyer's records to verify the information contained in
such reports.

                  (b)   If the Warranty Costs and Recall Costs at
any time during either of the 12 month periods immediately
following the Closing Date shall exceed (i) $1,000,000 in the
aggregate for the first twelve months following the Closing Date,
and/or (ii) $800,000 in the aggregate for the next succeeding
twelve months, Buyer shall give notice thereof to Sellers and
within thirty (30) days after receipt of any such notice Sellers
shall pay to Buyer the amount of any such excess in each of such
12 month periods.  Buyer shall bill Sellers monthly for such
excess costs.  If Sellers shall dispute any such bill, or whether
such matter in fact involves Product or Service Warranty or a
government mandated recall, the parties shall confer with regard

<PAGE>
to the matter and an appropriate adjustment and payment shall be
made if and to the extent agreed upon by the parties.  If they
are unable to resolve any such disputed bill within thirty (30)
days after Sellers' receipt thereof the matter shall be resolved
in accordance with the procedures set forth in Section 2.3(c)
with respect to disputes relating to the Final Statement.

            9.1   Survival.  All representations, warranties and
agreements by Sellers as set forth in this Agreement and the
Schedules hereto shall survive the Closing Date, notwithstanding
any investigation at any time by or on behalf of Buyer (subject,
however, to the limitations set forth in Section 9.7 of this
Agreement); provided, however, that the representations and
warranties contained in (a) Sections 4.5, 4.7(b), 4.7(d), 4.7(e),
4.7(g), 4.7(h), 4.7(i), 4.8, 4.9, 4.10, 4.11, 4.12, 4.13,

asserted by Buyer for misrepresentation or breach of warranty

Schedules, and (b) Section 4.25 shall expire with respect to each

Warranty described therein shall expire by its terms and

Agreement or in connection with the transactions contemplated by
this Agreement shall be considered representations and warranties
by Buyer to Sellers with the same force and effect as if
contained in this Agreement.  All representations, warranties and
agreements by Buyer shall survive the Closing notwithstanding any
investigation at any time by or on behalf of Sellers, and shall
not be considered waived by Sellers' consummation of the sale
contemplated by this Agreement with knowledge of any breach or
misrepresentation by Buyer; provided, however, that the
representations and warranties contained in Sections 5.4 through
and including 5.6 of this Agreement shall expire eighteen (18)
months after the Closing Date and thereafter no claim shall be
asserted by Sellers for misrepresentation or breach of warranty
with respect to those Sections.
<PAGE>

            9.2   Sellers' Indemnification Obligation.  Each Seller
shall indemnify and hold harmless Buyer and its Affiliates
against all claims of, and all actual loss, liability, actual
damage or out-of-pocket expense, including reasonable fees and
expenses of counsel, whether involving a third party or between
the parties to this Agreement (a "Buyer Loss"), Buyer may suffer,
sustain or become subject to as a result of (a) any breach of any
warranties, covenants or other agreements contained in this
Agreement, or any misrepresentation by any Seller, or any
warranty or representation not being true as of the Closing or a
claim by a third party which, without regard to the merits of the
claim, would constitute such a breach or misrepresentation if
such third party's allegations were true; (b) any Seller's
failure to fully pay, perform and discharge when the same become
due and payable the Excluded Liabilities; (c) any of Sellers'
other obligations, liabilities, agreements or commitments that do
not arise out of or are not in connection with the operation of
the Business and/or the Assets; (d) any failure to comply with
any "bulk sales" laws applicable to the transactions contemplated
hereby; and (e) any obligation or liability relating to any
Benefit Plan or arrangement (including the Benefit Plans)
sponsored, maintained or contributed to by Sellers or a Common
Control Entity on or prior to the Closing Date to any person or
entity, including the Employees, any such plan or the
participants (or their beneficiaries) in any such plan, whether

<PAGE>
such liability is incurred on, prior to or after the Closing Date
(including, without limitation, any liability relating to
benefits provided under any post-retirement welfare benefit
plan), and any obligation or liability to any Employee or other
present or former employee of any Seller, or to any dependent,
survivor or beneficiary thereof, arising out of or relating to
any such person's employment with any Seller on or prior to the
Closing Date.  

            9.3   Buyer Indemnification Obligation.  Buyer and
Guarantor shall jointly and severally indemnify and hold harmless
Sellers against all claims of, and all actual loss, liability,
actual damage or out-of-pocket expense, including reasonable fees
and expenses of counsel (a "Seller Loss" and, together with a
Buyer Loss, an "Indemnified Loss"), Sellers may suffer, sustain
or become subject to as a result of (a) any breach of any
warranties, covenants or other agreements contained in this
Agreement or any misrepresentation by Buyer, or a claim by a
third party which, without regard to the merits of the claim,
would constitute such a breach or misrepresentation if such third
party's allegations were true; (b) the operations of the Business
and/or the Assets after the close of business on the Closing
Date; (c) Buyer's failure to fully pay, perform and discharge
when the same become due and payable the Assumed Liabilities; (d)
any of Buyer's other obligations, liabilities, agreements or
commitments arising out of or in connection with the operation of

<PAGE>
the Business after the close of business on the Closing Date, in
each case except to the extent Sellers are obligated to indemnify
Buyer for a breach of representation or warranty pursuant to
Section 9.2(a) of this Agreement, subject, however, to the
limitations on indemnification and on survival of such
representations and warranties as provided in this Agreement.

            9.4   Conditions of Indemnification for Third Party
Claims.  The obligations and liabilities of the parties under
this Agreement with respect to, relating to, caused (in whole or
in part) by or arising out of claims of third parties (individ-
ually, a "Third Party Claim" and collectively "Third Party
Claims") including, without limitation, any Tax Authority, shall
be subject to the following terms and conditions:

                  (a)   The party entitled to be indemnified
hereunder (the "Indemnified Party") shall give the party
obligated to provide the indemnity (the "Indemnifying Party")
prompt notice of any Third Party Claim, and, provided that the
Indemnifying Party acknowledges in writing its obligation to
indemnify in accordance with the terms of this Agreement, the
Indemnifying Party may undertake the defense of that claim by
representatives chosen by it.  Any such notice of a Third Party
Claim shall identify with reasonable specificity the basis for
the Third Party Claim, the facts giving rise to the Third Party
Claim, and the amount of the Third Party Claim (or, if such

<PAGE>
amount is not yet known, a reasonable estimate of the amount of
the Third Party Claim).  The Indemnified Party shall make
available to the Indemnifying Party copies of all relevant
documents and records in its possession.  Failure to give prompt
notice shall not relieve the Indemnifying Party of its obligation
to indemnify except to the extent that the Indemnifying Party is
actually prejudiced by the delay in giving notice.

                  (b)   If the Indemnifying Party, within 15 days
after notice of any such Third Party Claim (or such lesser time
as is reasonable), fails to assume the defense in accordance with
Section 9.4(a) of this Agreement, the Indemnified Party shall
(upon further notice to the Indemnifying Party) have the right to
undertake the defense, compromise or settlement of the Third
Party Claim, subject to the right of the Indemnifying Party to
assume the defense of such Third Party Claim at any time prior to
settlement, compromise or final determination thereof, provided,
however, that at the time of the assumption of defense the
Indemnifying Party shall acknowledge in writing its obligation to
indemnify as provided in Section 9.4(a) of this Agreement and
reimburse the Indemnified Party for its out-of-pocket expenses
incurred prior to the assumption of defense by the Indemnifying
Party.

                  (c)   Anything in this Section 9.4 to the contrary
notwithstanding, (i) the Indemnifying Party shall not, without

<PAGE>
the written consent of the Indemnified Party, settle or compro-
mise any Third Party Claim or consent to the entry of judgment
which does not include as an unconditional term thereof the
giving by the claimant or the plaintiff to the Indemnified Party
of an unconditional release from all liability in respect of the
Third Party Claim; and (ii) if there is a reasonable probability
that a claim may materially and adversely affect the Indemnified
Party other than as a result of money damages or other money
payments for which the Indemnified Party is indemnified
hereunder, the Indemnified Party shall have the right, at its own
cost and expense, to participate in the defense of the Third
Party Claim (control of the defense to remain with the
Indemnifying Party).

            9.5   Deductible and Cap.

                  (a)   Deductible.  Except for claims under Section
9.2(a) with respect to representations and warranties, no claim
for indemnification under Section 9.2 may be made by Buyer unless
such claim along with all prior claims, Waived Claims and Damage
Deductibles is, with respect to an Indemnified Loss equal to or
exceeding $200,000 in the aggregate.  Except for claims under
Section 9.3(a) with respect to representations and warranties, no
claim for indemnification under Section 9.3 may be made by
Sellers unless such claim along with all prior claims is, with
respect to an Indemnified Loss equal to or exceeding $200,000 in

<PAGE>
the aggregate.  In addition, the amount which an Indemnified
Party shall be entitled to receive from an Indemnifying Party
under this Section 9.5 with respect to an Indemnified Loss shall
be net of any recovery actually received from third parties
(including insurance proceeds, counterclaims, subrogation actions
and the like) or actually reimbursed after all costs of
collection on account of such Indemnified Loss.

                  (b)   Cap.  In no event whatsoever shall the
liability of Sellers or Buyer with respect to Indemnified Losses
exceed the purchase price hereunder; provided, however, that this
Section 9.5(b) shall not apply with respect to an Indemnified
Loss with respect to an Excluded Liability or an Assumed
Liability.

            9.6   Time Limits On Indemnification.  No claim on
account of misrepresentation or breach of warranty shall be made
beyond the survival periods referred to in Section 9.1 of this
Agreement.  No claim for indemnification may be made by any
Seller against Guarantor after five (5) years from the Closing
Date.

            9.7   Limits On Indemnification.  If at the Closing,
Buyer has Actual Knowledge that any of Sellers' representations
or warranties contained in this Agreement are untrue, then Buyer
shall be limited to the following options:
<PAGE>

                  (a)   to elect to terminate this Agreement; or

                  (b)  to elect to close the transactions
contemplated by this Agreement, notwithstanding such
misrepresentation or breach of warranty, in which event such
transactions shall be consummated in accordance with the
provisions of this Agreement and Sellers shall have no liability
hereunder by reason of such misrepresentation or breach of
warranty ("Waived Claims").  For purposes hereof:  Buyer shall be
deemed to have had "Actual Knowledge" of a matter if any of the
persons listed on Schedule 9.7 had actual knowledge of such
matter, and shall not be deemed to include any knowledge that any
of the foregoing (i) should have had or should be imputed to have
had because of the services of such persons through the Closing
to the Buyer or (ii) had, or should have had or should be imputed
to have had solely by virtue of the fact that such matter was
contained in any of the due diligence materials provided by
Sellers to Buyer.

      10.   Termination.

            10.1  Termination.  This Agreement may be terminated:

                  (a)   by written agreement of Buyer and Sellers;
or
<PAGE>

                  (b)   by Buyer, if a Required Consent is not
obtained prior to or at the Closing; or 

                  (c)   by Buyer, pursuant to Section 9.7 of this
Agreement; or

                  (d)   by Buyer or Sellers as provided in Section
11 of this Agreement; or

                  (e)   by Buyer or Sellers as provided in Section
3.2 of this Agreement. 

            10.2  Liability.  The termination of this Agreement
hereunder shall not relieve any party of any liability for breach
of this Agreement prior to the termination.

      11.   Risk of Loss; Damage to Facilities.

            11.1  Major Taking.  In the event of a condemnation or
taking by eminent domain of all or any portion of the Real
Property, Buyer may elect to terminate this Agreement upon
written notice to Sellers, unless it is a "Minor Taking" (as
hereinafter defined) in which case the provisions of Section 11.2
shall apply.


<PAGE>
            11.2  Minor Taking.  In the event of a Minor Taking
prior to Closing, Buyer shall nevertheless take title to the Real
Property on the Closing Date, subject to such condemnation or
taking by eminent domain, without any abatement in the Base
Purchase Price provided that the entire condemnation award
applicable to such Real Property shall, on the Closing Date, be
assigned to Buyer or, if received by any Seller prior to the
Closing Date, be paid by such Seller to Buyer at the Closing (net
of the reasonable costs of collection actually paid or incurred
by Sellers), in either such case, free and clear of Liens.  For
the purposes of this Agreement, a "Minor Taking" shall mean a
condemnation or taking by eminent domain whereby less than 5% of
any parcel of the Real Property is taken and no interference in
any material respect with the current operation, occupancy or
maintenance of taken Real Property or portion of the Business
conducted thereon or the other Assets could reasonably be
expected to result therefrom.  Buyer shall have the right, at its
sole cost and expense, to participate in any proceedings prior to
the Closing with respect to a condemnation or taking, and shall
have the right to approve the settlement of any such proceeding
relating to a Minor Taking, which approval shall not be
unreasonably withheld or delayed.

            11.3  Minor Damage.


<PAGE>
                  (a)  In the event of damage or destruction to any
material portion of the Assets first occurring after the date of
this Agreement and prior to the Closing, of which Sellers obtain
actual knowledge and which Sellers reasonably believe would
involve more than $25,000 to repair or replace, Sellers shall
promptly give Buyer notice thereof and retain a contractor or
other professional reasonably acceptable to Buyer (the
"Acceptable Contractor") to estimate the cost of restoration
and/or replacement thereof, and shall instruct such Acceptable
Contractor to deliver its written estimate of such restoration
and/or replacement cost to Sellers and Buyer as soon as
reasonably practicable.  If the cost of restoring and/or
replacing such Assets, in the reasonable judgment of such
Acceptable Contractor, is $100,000 or less in the aggregate,
Buyer shall have the option, to be exercised by written notice to
Sellers within thirty (30) days after the restoration and/or
replacement cost has been determined by the Acceptable
Contractor, as provided above, either:

                        (i)   to proceed with the acquisition of all
            the Assets at the Closing, in which case at the
            Closing, Sellers shall disburse to Buyer the amount of
            any insurance proceeds (less deductibles ("Damage
            Deductibles")) to the extent at that time actually
            collected by Sellers in connection with such damage or
            destruction and Sellers shall assign all Sellers'

<PAGE>
      rights to receive any such proceeds (less Damage
      Deductibles) in the future free and clear of any Liens
      thereon and claims thereto, less the reasonable costs of
      collection actually paid or incurred by Sellers in
      connection therewith (the "Net Insurance Proceeds"); or

                        (ii)     if the damage or destruction (1)
            can reasonably be expected to interfere in any material
            respect with the operation of the Business as presently
            operated and/or the Assets, or (2) shall create in the
            Assets an environmentally hazardous condition which
            pursuant to applicable law requires remediation
            ("Hazardous Condition"), to elect to terminate this
            Agreement.

                  (b)   Notwithstanding the foregoing, in the event
that a Hazardous Condition is created by any such damage or
destruction which could reasonably be expected to expose Sellers
to liabilities resulting therefrom in excess of $500,000 and/or
such damage or destruction could reasonably be expected to expose
Sellers under the Assigned Agreements to liabilities in excess of
$500,000 by reason of delays or Sellers inability to perform its
obligations under the Assigned Agreements prior to the Closing
Date, then Sellers may elect to terminate this Agreement.


<PAGE>
            11.4  Major Damage.

                  (a)   In the event of damage or destruction to the
Assets first occurring after the date hereof and prior to the
Closing and the cost of restoring and/or replacing the Assets, in
the reasonable judgment of the Acceptable Contractor retained by
Sellers, is greater than $100,000 in the aggregate, Buyer shall
have the option, to be exercised by written notice to Sellers
within thirty (30) days after the restoration and/or replacement
cost has been determined by the Acceptable Contractor, as
provided above, either:

                        (i)   to proceed with the acquisition of all
      the Assets at the Closing, in which case at the Closing
      Sellers shall disburse to Buyer the amount of Net Insurance
      Proceeds (less Damage Deductibles) to the extent at that
      time collected by Sellers and Sellers shall assign all
      Sellers' rights to receive any Net Insurance Proceeds (less
      Damage Deductibles) in the future free and clear of any
      Liens thereon and claims thereto; or 

                        (ii)        to elect to terminate this
Agreement.

                  (b)   Notwithstanding the foregoing, in the event
that a Hazardous Condition is created by any such damage or

<PAGE>
destruction which could reasonably be expected to expose Sellers
to liabilities resulting therefrom in excess of $500,000 and/or
such damage or destruction could reasonably be expected to expose
Sellers under the Assigned Agreements to liabilities in excess of
$500,000 by reason of delays or Sellers inability to perform its
obligations under the Assigned Agreements prior to the Closing
Date, then Sellers may elect to terminate this Agreement.

            11.5  Notice of Casualty or Condemnation.  In the event
any casualty or condemnation shall affect the Assets after the
date hereof and prior to the Closing, Sellers shall promptly
notify Buyer thereof promptly after Sellers obtain actual
knowledge of any such casualty or notice of condemnation and
provide Buyer with reasonably detailed information with respect
thereto.

      12.   Miscellaneous.

            This amendment (this "First Amendment") to the Purchase

between Sequa Corporation ("Sequa"), Kollsman Manufacturing
Company, Inc. ("KMC") and Sequa Export Corporation ("Export", and

            A.    Sellers, Buyer and Guarantor have entered into
that certain Purchase Agreement, dated as of November 9, 1995
(the "Agreement"), pursuant to which, among other things, Sellers
have agreed to sell to Buyer, and Buyer has agreed to purchase

            B.    Sellers, Buyer and Guarantor, simultaneously with

Letter Agreement, dated as of November 9, 1995 (the "Letter
Agreement"), relating, among other things, to the preparation,

            C.    Sellers and Buyer have agreed upon some of the
Schedules referred to in the Agreement.<PAGE>
<PAGE>
                             TERMS AND CONDITIONS
            NOW, THEREFORE, in consideration of the premises and
for other good and valuable consideration, and intending to be
legally bound hereby, Sellers, Buyer and Guarantor hereby agree
as follows:

                                   ARTICLE 1
                              General Provisions

            1.1   Definitions.  All capitalized terms used, but not
otherwise defined in this First Amendment, shall have the
respective meanings ascribed thereto in the Agreement.

            1.2   Other Definitions and Meanings:  Interpretations. 
For purposes of this First Amendment the term "parties" (except
where the context otherwise requires) means Sellers, Buyer and
Guarantor; the term "person" includes any natural person, firm,
association, partnership, corporation, or entity other than the
parties, and the words "hereof", "hereby" and other words of
similar import refer to this First Amendment as a whole.  The
headings of the Articles and Sections of this First Amendment
have been included herein for convenience of reference only and
shall not be deemed to affect the meaning of the operative
provisions of this First Amendment.

            1.3   Relationship with the Agreement.  This First
Amendment is intended to amend the Agreement as and to the extent
set forth herein.  The Agreement, and each and every provision
thereof, will otherwise remain in full force and effect and each
of the parties reserves all of their respective rights contained
therein.

                                   ARTICLE 2
                               Letter Agreement


<PAGE>
            2.1   Termination of Letter Agreement.  The Letter
Agreement is hereby terminated effective immediately and,
accordingly shall be of no further force and effect and the
parties shall have no further liability thereunder.

            2.2   Governmental Filings.  Sellers, on the one hand,
and Buyer, on the other, have filed with each of the Department
of Justice and the Federal Trade Commission the report and
notification required to be filed by them under the Hart-Scott-
Rodino Anti-Trust Improvements Act of 1976 in connection with the
transactions contemplated by the Agreement.  The $45,000 filing
fee has been shared equally by Sellers, on the one hand, and
Buyer, on the other.  If the transactions contemplated by the
Agreement close in accordance with the Agreement (as amended
herein), Buyer shall reimburse Sellers at the Closing for the
$22,500 paid by Sellers for such filing.

                                   ARTICLE 3
                        Amendment of Purchase Agreement

            3.1   Agreed Upon Schedules.  The parties agree and
acknowledge that they have agreed upon the form and substance of
the Schedules to the Agreement that are listed on Schedule A
attached hereto (the "November 29, 1995 Agreed Upon Schedules"). 
Simultaneously with the execution of this First Amendment, Reuben
Ben-Arie, on behalf of Buyer and Guarantor, and Joseph C.
Allwarden, on behalf of Sellers, have initialled for
identification the November 29, 1995 Agreed Upon Schedules. 
Accordingly, the Agreement is hereby amended in order to reflect
the November 29, 1995 Agreed Upon Schedules, with the same effect
as if they had been agreed upon and attached to the Agreement
simultaneously with its execution.

            3.2   Other Schedules and Exhibits.  All Schedules or
Exhibits that are referred to in the Agreement other than
Schedule 2.3(b)-2 (Accounting

<PAGE>
Instructions) and the November 29, 1995 Agreed Upon Schedules
(the "Open Schedules and/or Exhibits") have not been finalized or
agreed upon as between the parties.  Accordingly, on or before
December 8, 1995, Sellers, on the one hand, and Buyer, on the
other, shall finalize the Open Schedules and/or Exhibits.  If
agreed upon in each such party's sole and absolute discretion,
Sellers and Buyer, shall initial the agreed upon Open Schedules
and/or Exhibits and the same shall be the subject of a further
amendment to the Agreement in substantially the form of this
First Amendment.  If, on or before December 8, 1995, Sellers or
Buyer object in writing to any Open Schedules and/or Exhibits
received by them or otherwise fail to agree upon the form and
substance of the Open Schedules and/or Exhibits, then the
objecting parties may, at their sole and absolute election,
terminate the Agreement (as amended herein) and no party shall
have any further rights or obligations thereunder.  For purposes
of delivering Open Schedules and/or Exhibits, delivery shall be
deemed to have been made upon delivery of the same (i) in the
case of Buyer, to Buyer's counsel, Proskauer Rose Goetz &
Mendelsohn LLP, Attention: Michael E. Feldman, Esq., (ii) in the
case of Sellers, to Sellers' counsel, John J. Dowling III, Sequa
Corporation, 120 South Central Avenue, St. Louis, Mo. 63105.

            3.3   New Outside Dates.   Section 3 of the Agreement is
hereby amended and restated so as to read in its entirety as
follows:

                             TERMS AND CONDITIONS


<PAGE>
            NOW, THEREFORE, in consideration of the premises and
for other good and valuable consideration, and intending to be
legally bound hereby, Sellers, Buyer and Guarantor hereby agree
as follows:

                                   ARTICLE 1
                              General Provisions

            1.1   Definitions.  All capitalized terms used, but not
otherwise defined in this Second Amendment, shall have the
respective meanings ascribed thereto in the Agreement.

            1.2   Other Definitions and Meanings:  Interpretations. 
For purposes of this Second Amendment the term "parties" (except
where the context otherwise requires) means Sellers, Buyer and
Guarantor; the term "person" includes any natural person, firm,
association, partnership, corporation, or entity other than the
parties, and the words "hereof", "hereby" and other words of
similar import refer to this Second Amendment as a whole.  For
purposes of this Second Amendment, the term "November 29, 1995
Agreed Upon Schedules" shall have the meaning set forth in the
First Amendment.  The headings of the Articles and Sections of
this Second Amendment have been included herein for convenience
of reference only and shall not be deemed to affect the meaning
of the operative provisions of this Second Amendment.

            1.3   Relationship with the Agreement and prior
amendment.  This Second Amendment is intended to amend the
Agreement as and to the extent set forth herein.  The Agreement
and the First Amendment, and each and every provision thereof,
will otherwise remain in full force and effect to the extent not
superseded by this Second Amendment and each of the parties
reserves all of their respective rights contained therein.


<PAGE>
                                   ARTICLE 2
                        Amendment of Purchase Agreement

            2.1   Agreed Upon Schedules.  The parties agree and
acknowledge that they have agreed upon the form and substance of
the Schedules to the Agreement that are listed on Schedule A
attached hereto (the "December 1, 1995 Agreed Upon Schedules"). 
Simultaneously with the execution of this Second Amendment,
Reuben Ben-Arie, on behalf of Buyer and Guarantor, and Joseph C.
Allwarden, on behalf of Sellers, have initialled for
identification the December 1, 1995 Agreed Upon Schedules. 
Accordingly, the Agreement is hereby amended in order to reflect
the December 1, 1995 Agreed Upon Schedules, with the same effect
as if they had been agreed upon and attached to the Agreement
simultaneously with its execution.

            2.2   Other Schedules and Exhibits.  All Schedules or
Exhibits that are referred to in the Agreement other than
Schedule 2.3(b)-2 (Accounting Instructions), the November 29,
1995 Agreed Upon Schedules and the December 1, 1995 Agreed Upon
Schedules (the "Open Schedules and/or Exhibits") have not been
finalized or agreed upon as between the parties.  Accordingly, on
or before December 8, 1995, Sellers, on the one hand, and Buyer,
on the other, shall finalize the Open Schedules and/or Exhibits. 
If agreed upon in each such party's sole and absolute discretion,
Sellers and Buyer, shall initial the agreed upon Open Schedules
and/or Exhibits and the same shall be the subject of a further
amendment to the Agreement in substantially the form of this
Second Amendment.  If, on or before December 8, 1995, Sellers or
Buyer object in writing to any Open Schedules and/or Exhibits
received by them or otherwise fail to agree upon the form and
substance of the Open Schedules and/or Exhibits, then the
objecting parties may, at their sole and absolute election,
terminate the Agreement (as amended) and no party shall have any
further rights or obligations thereunder.  For purposes of
delivering Open Schedules and/or Exhibits, delivery shall be
deemed to have been made upon

counsel, Proskauer Rose Goetz & Mendelsohn LLP, Attention:
Michael E. Feldman, Esq., and (ii) in the case of Sellers, to
Sellers' counsel, John J. Dowling III, Sequa Corporation, 120
South Central Avenue, St. Louis, Mo. 63105.

            2.3   Certain Notifications.  A new Section 6.8A shall
be added to the Agreement which shall read in its entirety as
follows:

                  "6.8A  Certain Notices.  Sellers shall, on or
prior to December 4, 1995, send to all parties to any Customer
Agreement or Teaming Agreement (x) listed on Schedule 6.8 a
request for its consent to, or (y) listed on Schedule 6.8A a
notice of, the proposed assignment of that agreement to Buyer. 
For purposes of this Agreement, a "Required Consent" shall be
deemed not to have been obtained if:  (x) any customer or teaming
partner listed on Schedule 6.8A of this Agreement notifies any
Seller or Buyer that it is considering termination, non-renewal
or any adverse modification of the applicable Customer Agreement
or Teaming Agreement or shall indicate that its unwillingness to
continue its business relationship with Sellers and/or Buyer, or
(y) one or more customers shall have notified Sellers or Buyer
that they are considering termination, non-renewal or any adverse
modification of one or more agreements having an aggregate value
of $1,000,000 or more or shall indicate that their unwillingness
to continue their business relationship with Sellers and/or
Buyer."

                                   ARTICLE 3
                                 Miscellaneous

            3.1   Severability.  If any provision of this Second
Amendment shall finally be determined to be unenforceable, then
such provision shall be deemed to be severed from this Second
Amendment and every other provision of this Second Amendment
shall remain in full force and effect.

            3.2   Counterparts.  More than one counterpart of this
Second Amendment may be executed by the parties hereto, and each
fully-executed counterpart shall be deemed an original without
production of the others.  The parties acknowledge that they are
delivering to each other facsimile counterparts of this Second
Amendment and the December 1, 1995 Agreed Upon Schedules, signed
and initialled on their behalf, and agree that such signature and
initialization shall be binding upon each of them as if the

<PAGE>
counterparts being delivered to the other parties had been
originally signed and initialized.

            3.3   Complete Agreement.  The Agreement (as amended),
the First Amendment and this Second Amendment set forth the
entire understanding of the parties with respect to the subject
matter thereof and, together, supersede all prior letters of
intent, agreements (including, without limitation, the Letter
Agreement), covenants, arrangements, communications,
representations, or warranties, whether oral or written, by any
officer, employee, or representative of either party relating
thereto.

            3.4   Acknowledgement.  Sellers and Buyer acknowledge
that each of them has been informed by the other that if either:
(x) they are unable for any reason whatsoever, in their
respective sole and absolute discretion, to timely agree upon the
form and substance of the Open Schedules and/or Exhibits in
accordance with Section 2.2 above, or (y) any of the deadlines
set forth in Section 3 of the Agreement (as amended) shall not
have been timely met for any reason whatsoever, then, in either
such event, neither party shall be obligated to grant any further
extensions to this Second Amendment or the Agreement (as
amended), that they shall not grant such an extension and that
they shall, instead, terminate the Agreement (as amended) and
this Second Amendment.  Sellers have additionally advised Buyer
that they are unwilling and unable to consummate any transaction
after December 21, 1995.

                        Amendment of Purchase Agreement

            2.1   Agreed Upon Schedules.  The parties agree and
acknowledge that they have agreed upon the form and substance of
the Schedules to the Agreement that are listed on Schedule A
attached hereto (the "December 8, 1995 Agreed Upon Schedules"). 
Simultaneously with the execution of this Third Amendment, either
Reuben Ben-Arie or Michael E. Feldman (as attorney-in-fact) on
behalf of Buyer and Guarantor, and John J. Dowling III, on behalf
of Sellers, have initialled for identification the December 8,
1995 Agreed Upon Schedules.  Accordingly, the Agreement is hereby
amended in order to reflect the December 8, 1995 Agreed Upon
Schedules, with the same effect as if they had been agreed upon
and attached to the Agreement simultaneously with its execution.

            2.2   Other Schedules and Exhibits.  All Schedules or
Exhibits that are referred to in the Agreement other than
Schedule 2.3(b)-2 (Accounting Instructions), the November 29,
1995 Agreed Upon Schedules, the December 1, 1995 Agreed Upon
Schedules and the December 8, 1995 Agreed Upon Schedules (the
"Open Schedules and/or Exhibits") have not been finalized or
agreed upon as between the parties.  Accordingly, on or before
December 13, 1995, Sellers, on the one hand, and Buyer, on the
other, shall finalize the Open Schedules and/or Exhibits.  If
agreed upon in each such party's sole and absolute discretion,
Sellers and Buyer, shall initial the agreed upon Open Schedules
and/or Exhibits and the same shall be the subject of a further
amendment to the Agreement in substantially the form of this
Third Amendment.  If, on or before December 13, 1995, Sellers or
Buyer object in writing to any Open Schedules and/or Exhibits
received by them or otherwise fail to agree upon the

<PAGE>
form and substance of the Open Schedules and/or Exhibits, then
the objecting parties may, at their sole and absolute election,
terminate the Agreement (as amended) and no party shall have any
further rights or obligations thereunder.  For purposes of
delivering Open Schedules and/or Exhibits, delivery shall be
deemed to have been made upon delivery of the same (i) in the
case of Buyer, to Buyer's counsel, Proskauer Rose Goetz &
Mendelsohn LLP, Attention: Michael E. Feldman, Esq., and (ii) in
the case of Sellers, to Sellers' counsel, John J. Dowling III,

            prior to 12:01 a.m. on December 16, 1995.

      Upon termination pursuant to this Section 3.2 neither of the
      parties shall have any liability of any kind arising out of
      this Agreement other than for any liability resulting from
      its breach of this Agreement prior to termination.  If the
      Closing is postponed pursuant to Section 11 of this
      Agreement, and this Agreement is not otherwise terminated in
      accordance with the provisions of Section 11, the outside

                                   ARTICLE 3
                                 Miscellaneous

            3.1   Severability.  If any provision of this Third

Amendment and every other provision of this Third Amendment shall
remain in full force and effect.

            3.2   Counterparts.  More than one counterpart of this
Third Amendment may be executed by the parties hereto, and each

production of the others.  The parties acknowledge that they are
delivering to each other facsimile counterparts of this Third
Amendment and the December 8, 1995 Agreed Upon Schedules, signed
and initialled on their behalf, and agree that such signature and
initialization shall be binding upon each of them as if the
counterparts being delivered to the other parties had been
originally signed and initialized.

            3.3   Complete Agreement.  The Agreement (as amended),
the First Amendment, the Second Amendment and this Third
Amendment set forth the entire understanding of the parties with
respect to the subject matter thereof and, together, supersede

respective sole and absolute discretion, to timely agree upon the
form and substance of the Open Schedules and/or Exhibits in
accordance with Section 2.2 above, or (y) any of the deadlines

            3.1   Severability.  If any provision of this Eighth
Amendment shall finally be determined to be unenforceable, then

agree that each of them has been informed by the other that if
any of the deadlines set forth in Section 3 of the Agreement (as
amended) shall not have been timely met for any reason
whatsoever, then, in such vent, neither party shall be obligated

sole and absolute discretion (which may be subjective) and the
Agreement (as amended) shall automatically terminate without
