Item 2.      Acquisitions and Dispositions of Assets.

On December 30, 1993, Sequa Corporation and certain of its
subsidiaries and affiliates (collectively "Sequa") entered into a
Stock Purchase Agreement ("Stock Purchase Agreement") pursuant to
which Sequa sold all of the issued and outstanding capital stock
of ARC Professional Services Group, Inc., Atlantic Research
Corporation UK Limited, Atlantic Research Canada Inc. and ARC
Interoperability Systems International, S.A. (collectively "ARC
PSG") to Computer Sciences Corporation and certain of its
subsidiaries and affiliates (collectively "CSC").  In this
transaction, Sequa received $59.9 million in cash (subject to
final cash settlement adjustments) and CSC assumed $4.6 million
of ARC PSG's debt.  Proceeds from the sale, together with cash on
hand, were used to repay debt and to purchase the 7% minority
interest in Atlantic Research Corporation ("ARC").

ARC PSG employed approximately 2,000 employees in the United
States, Canada, United Kingdom and Greece.  Engaged in
information technology and technical services for both the
governmental and civil sectors, ARC PSG had in excess of 240
government contracts and generated revenues in excess of $160
million during 1993.

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

(b)    Unaudited pro forma financial information of Sequa
       Corporation reflecting the sale of ARC PSG

The unaudited Pro Forma Consolidated Balance Sheet at September
30, 1993 and unaudited Pro Forma Statements of Consolidated
Income for the nine months ended September 30, 1993 and the year
ended December 31, 1992 give effect to the sale of ARC PSG and
other directly related transactions, based upon the assumptions
set forth below and in the notes to such statements.  The pro
forma financial information assumes that the transactions for
which pro forma effects are shown were completed September 30,
1993 for the Pro Forma Consolidated Balance Sheet, and January 1
of each period presented for the Pro Forma Statements of
Consolidated Income.  The Pro Forma Consolidated Balance Sheet at
September 30, 1993 includes a $10.2 million after-tax gain on the
sale of ARC PSG and a $2.1 million after-tax extraordinary loss
on the extinguishment of debt which was repaid with the proceeds
from the sale.  These two pro forma adjustments have not been
made to the Pro Forma Statements of Consolidated Income as they
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 ARC
PSG 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, 1993.  The pro forma adjustments relating
to the disposition of ARC PSG are based on a preliminary purchase
price which is subject to final cash settlement adjustments
within 30 days of the December 30, 1993 closing date. 
Accordingly, Sequa's actual recording of the disposition of ARC
PSG 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 provided for comparative purposes only.  The pro forma
information presented does not purport to be indicative of the
results that may be obtained in the future.

a negative or positive number) of the net cash flow received by
and expended by Sellers in the course of PSG's and the Foreign
Subsidiaries' operations between September 24, 1993 and the
Closing, determined as follows:

             (a)    Cash Settlement Statement: Not more than thirty
(30) days after the Closing Date, Sellers will prepare and
deliver to Purchasers a proposed Cash Settlement Statement
reflecting the net change from September 24, 1993 through the
Closing Date in the accounts carried on PSG's internal
consolidating balance sheet as "Cash," "Intercompany Account -
Sequa Corporation," "Intercompany Account - ARC & Aerospace," and
"Intercompany Account - Janus".  In determining the net change in
the foregoing accounts (1) non-cash transactions, such as any
allocation of Sequa general and administrative expense and costs
of funds, shall be ignored, (2) cash and cash equivalents held in
bank accounts outside of the United States of America on the
Closing Date shall be excluded from the calculation, (3) Sellers
shall be credited with the amount of petty cash held by PSG that
is retained by PSG at the Closing, (4) the funds received on
behalf of PSG as a result of the payments made under Sections
2.1(a)(1) and (a)(2) hereof shall be excluded and (5) the change
in the account balances shall be presented by major transaction
type in the format shown in Exhibit 2.4 hereto.  A negative Cash
Settlement Adjustment shall result in a reduction from the
Aggregate Purchase Price by such amount.  Conversely, a positive
Cash Settlement Adjustment shall result in an addition to the
Aggregate Purchase Price by such amount.

             (b)    Review by Enterprises: Following receipt of the
proposed Cash Settlement Statement, Enterprises shall have a
period of thirty (30) days to review the proposed Cash Settlement
Statement.  During such period, Sellers shall make available

any questions of Enterprises relating to the proposed Cash

Statement and the entries thereon.  At or before the end of such
thirty (30) day period, Enterprises will either: (i) accept the
proposed Cash Settlement Statement in its entirety, in which case
the final Cash Settlement Adjustment will equal the balance set
forth on the proposed Cash Settlement Statement; or (ii) deliver
to ARC notice and a detailed explanation of those items in the
proposed Cash Settlement Statement which Enterprises disputes, in
which case the aggregate amounts not affected by the disputed
items will be deemed to be as set forth on the proposed Cash
Settlement Statement.  If Enterprises delivers the notice
referred to in (ii) above, then within a period of thirty (30)
days from the date of such delivery, the parties will attempt to
resolve in good faith any disputed items, and the Cash Settlement
Adjustment will equal the balance set forth on the Cash
Settlement Statement produced through such resolution.  Failing
such resolution, the unresolved disputed items will be referred
to final binding resolution to a nationally recognized firm of
certified public accountants other than Deloitte & Touche and
Arthur Andersen & Co., selected by lot by Sellers and
Enterprises, and the Cash Settlement Adjustment will equal the
balance set forth on the Cash Settlement Statement produced
through such resolution.

             (c)    Payment of and Interest on Amount of Cash
Settlement Adjustment: If the Aggregate Purchase Price plus or
minus the Cash Settlement Adjustment, as the case may be, is
greater than the payment made at Closing (as described in Section
2.l(b) hereof), then Enterprises will pay ARC by means of wire
transfer of immediately available funds to an account designated
by ARC the amount of such difference plus interest to date on the
amount of the difference within five (5) business days after
final agreement by the parties as to the Cash Settlement
Statement.  If the Aggregate Purchase Price plus or minus the
Cash Settlement Adjustment, as the case may be, is less than the
payment made at Closing (as described in Section 2.1(b) hereof),
then Sellers will pay to Enterprises the amount of such
difference plus interest on the amount of the difference within
five (5) business days after final agreement by the parties as to
the Cash Settlement Statement.  In either case, the rate of
interest shall be equal to the Applicable Rate.  Interest shall
accrue for the period from the Closing Date to the day before the
date on which the payment provided for under this Section 2.4(c)
is paid.

       2.5   Payment of Estimated Purchase Price: Not later than the
Closing Date, Purchasers and Sellers shall agree upon a
preliminary estimate of the amount of the Cash Settlement
Adjustment, based upon information supplied by Sellers as of the
most recent date practicable.  If such preliminary estimate
indicates that Sellers have received more cash flow than they
have expended for PSG's and the Foreign Subsidiaries' operations
since September 24, 1993, such that the preliminary estimate
indicates that the Cash Settlement Adjustment will be a negative
                                           7

number, then the term "Preliminary Cash Settlement Adjustment"
shall equal such negative number and onthe Closing Date,
Enterprises will pay, by means of a wire transfer of immediately
available funds to an account designated by ARC, an amount equal
to the Estimated PSG Price less the amount of the Preliminary
Cash Settlement Adjustment.  Otherwise, the Preliminary Cash
Settlement Adjustment shall be deemed to equal zero and on the
Closing Date, Enterprises will pay by means of a wire transfer of
immediately available funds to an account designated by ARC the
Estimated PSG Price.

<PAGE>
default; (4) PSG and the Foreign Subsidiaries are not in default

litigation, proceeding, action, material claim or investigation
pending in law or in equity against, or to the best of Seller's

properties or business nor, to Sellers' knowledge, is there any
of the foregoing threatened; and (2) PSG, the Foreign
Subsidiaries and their assets, properties or business are not

               Except as otherwise disclosed on Schedule 3.2(h) of
the Disclosure Package: (1) each of the Contracts is a valid and
binding obligation of PSG and/or the respective Foreign
Subsidiary entered into in the ordinary course of business and,

(including but not limited to individual employment and severance
agreements) under current law constitutes a payment that is
contingent upon the transactions provided for under this
Agreement that would be a "parachute payment" for purposes of
Code Section 280G.

               (2)         Schedule 3.2(i) of the Disclosure Package
identifies each Pension Plan and each Welfare Plan (the Welfare

Disclosure Package, there is no action, suit or claim pending
(other than routine claims for benefits) or, to Sellers'
knowledge, threatened against any ERISA Plan or the assets of any
ERISA Plan.  No civil or criminal action brought pursuant to the
provisions of Title I, Subtitle 8, Part 5 of ERISA is pending or,

upon any of such policies of insurance, and Sellers have no knowledge
of the existence of any facts that would constitute a valid basis for
any such claim, action, suit or proceeding.  There is no notice of
any pending or threatened termination or premium increase with
respect to any of such policies, and PSG and each of the Foreign
Subsidiaries is in material compliance with all conditions contained
therein.  PSG and

accrued, accruing, contingent or otherwise) as guarantor, surety, co-
signer, endorser, co-maker, indemnitor or otherwise in respect of the
obligation of any person, corporation, partnership, joint venture,

Closing, Sellers will, without further cost or expense to, or
consideration of any nature from Purchasers, execute and deliver, or
cause to be executed and delivered, to Purchasers, such additional
documentation and instruments, and will take such other and further
actions, as Purchasers may reasonably request as more completely to
sell, transfer and assign to and fully vest in Purchasers ownership
of the PSG Shares, the ARC/UK Shares, the ARC/Canada Shares and the
ARC/ISI Shares.

                    6.2    Further Consents to Assignment:   With respect
to those consents or approvals (or effective waivers thereof) to or
of assignment which are not obtained on or prior to Closing:

                           (a)   the parties will make all reasonable efforts
to obtain such consent or approval (or an effective waiver thereof)
at the written request therefor by Purchasers after Closing;

                           (b)   if the parties are unable to obtain such
consent or approval, or an effective waiver thereof, then, with
respect to the contract, lease, license, permit, approval or other
item of which such consent or approval of or to the effective
assignment is requested by Purchasers in writing at or after the
Closing: (1) 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 consent or approval, or an effective waiver
thereof, 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 (2) Sellers will cooperate with Purchasers in entering
into or effecting any reasonable arrangement designed to provide
Purchasers with the benefit of PSG's and each of the Foreign
Subsidiaries' rights under or pursuant to such item, including

                           (c)   Sellers will not be obligated to pay
consideration in order to obtain any consent or approval, or an
effective waiver thereof, pursuant to Section 6.2(b). Sellers will
cooperate with Purchasers in obtaining any required consent or
approval, or an effective waiver thereof, pursuant to an economic
arrangement satisfactory to Purchasers, provided, that Purchasers
will pay or reimburse Sellers for all third party costs incurred by




                                           41

one another free and full access to all of such records at reasonable
times and during normal business hours at the principal business
office of PSG and each of the Foreign Subsidiaries or of the Sellers,
as appropriate, or at such other location or locations at which such
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 such 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.  During such period, Purchasers will,
at Sellers' expense, cooperate with Sellers in furnishing
information, evidence, testimony, and other reasonable assistance in
connection with any action, proceeding, or investigation relating to
the business of PSG and each of the Foreign Subsidiaries prior to the

to cause each of the Foreign Subsidiaries to make arrangements to
notify their respective suppliers and customers of the change in
ownership and corporate name as soon as reasonably practicable
following the Closing hereunder.

                    6.5    Non-Compete:

                           (a)   In order to assure that the Purchasers will
realize the value and goodwill inherent in the acquisition of PSG and
the Foreign Subsidiaries, Sequa, Chromalloy and ARC agree with the
Purchasers that neither Sequa, Chromalloy, ARC, nor any of their
Affiliates shall:

                                 (1)    for a period of five (5) years
following the Closing Date, engage anywhere in the United States of


                                           42


<PAGE>
America or anywhere in other countries in which PSG conducted
business at any time during the two (2) years prior to the Closing,
in the business of providing services of the types presently or in
the past three (3) years provided by PSG or the Foreign Subsidiaries,
provided that Sequa, Chromalloy, ARC, and their Affiliates may
acquire assets or stock of companies collaterally engaged in the
business of providing such services to the extent that the assets
involved in such business or the revenues derived from such business
are not in excess of 30% of the assets or revenues of the acquired
business; and

                                 (2)    directly or indirectly for a period of
two (2) years following the Closing with respect to any Employee of
PSG or the Foreign Subsidiaries as of the Closing Date, solicit or
induce such person to terminate his or her employment with PSG or the
Foreign Subsidiary or to accept employment with Sequa, Chromalloy,
ARC or any of their Affiliates unless: (i) six (6) months has elapsed
since the last date of employment of such person with PSG or the
Foreign Subsidiaries; or (ii) such person was not personally
solicited by Sequa, Chromalloy, ARC or any of their Affiliates or any
agent engaged to act for any of them and such person has sought
employment with Sequa, Chromalloy, ARC or any of their Affiliates in
response to a general solicitation which is not directed to specific
individuals or companies and which solicitation is made through
newspaper advertisements or similar general forms of solicitation.

                           (b)   If any provision of paragraph (a) of this
Section, as applied to any party or to any circumstances, is adjudged
by a court to be invalid or unenforceable, the same will in no way
affect any other provision of the said paragraph (a) or any other
part of this Agreement, the application of such provision in any
other circumstances or the validity or enforceability of this
Agreement.  If any such provision, or any part thereof, is held to
be unenforceable because of the duration of such provision or the
area covered thereby, the parties agree that the court making such
determination will have the power to reduce the duration and/or
geographic area of such provision, and/or to delete specific words
or phrases, to the extent only that in its reduced form such
provision will then be enforceable and will be enforced.  Upon breach
of any provision of paragraph (a) of this Section, the Purchasers
will be entitled to injunctive relief, since the remedy at law would
be inadequate and insufficient.  In addition, the Purchasers will be
entitled to such damages as they can show themselves to have
sustained by reason of such breach.

                    6.6    Use of Trademark and Trade Names: Notwithstanding

stylized "ARC" and "Sequa" logos: (i) in

displays, signage and postings for two months after the Closing Date
to the extent such displays, signage or postings exist on the Closing
Date; (ii) with respect to all existing Contracts for the term of
such Contracts; (iii) for a period of two years, to state PSG's and
the Foreign Subsidiaries' former affiliation with ARC or Sequa (e.g.,
"formerly ARC Professional Services Group"); and (iv) to the extent
the trade names, trademarks, service marks or logos of any of
Sellers' Affiliates or of Sellers appear on PSG's or any Foreign
Subsidiary's stationary, packaging materials, supplies or inventory
on hand as of the Closing Date or on order at the time of the
Closing, until such is exhausted.  Purchasers shall also have the
right to use the trade names and trademarks set forth in Schedule 6.6
hereto without limitation.

                    6.7    Taxes:

                           (a)   Responsibility for Certain Taxes: Taxes
shall be apportioned as follows: (i) Sellers shall be responsible for
and shall pay, when due, all federal, state, foreign and local income
taxes of Sellers and PSG arising from the sale of PSG and the Foreign
Subsidiaries; (ii) PSG and the Foreign Subsidiaries are responsible
for completing the tax returns for and, except as provided in Section
6.7(a)(i) hereof, for payment of all Taxes of PSG and the Foreign
Subsidiaries, other than federal and foreign income taxes, to the
extent that such Taxes are not due and payable on or before the

by Sellers under Section 6.7(a)(i) hereof shall be paid by Sellers
to PSG or the Foreign Subsidiaries immediately prior to Purchasers'
filing of any such tax returns; (iii) Sellers are responsible for
completing the tax returns for, and for payment of, all federal and
foreign income taxes for any taxable period ending on or before the
Closing Date; (iv) notwithstanding anything in paragraph (a)(ii) of
this Section 6.7, Sellers are responsible for completing, on a
consolidated basis, the tax returns for and for payment of the state
income taxes of PSG for the States of California, Florida, Illinois
and Virginia, in which states Sellers file consolidated income tax
returns for all periods ending on or before or including the Closing
Date, provided, however, that the amount of such state income taxes
attributable to the operations of PSG during fiscal year 1993 on a
stand-alone basis, other than the amounts, if any, payable by Sellers
under Section 6.7(a)(i) hereof, shall be paid by PSG to Sellers
immediately prior to Sellers flag of such returns; and (v) Sellers
are responsible for any income taxes attributable to the pre-Closing
period in accordance with Section 6.7(b) hereof in the case of any

hereof, together with copies of the returns pursuant to which such
amounts are to be paid.  Sellers shall furnish to PSG calculations
as to the amounts, if any, payable by PSG pursuant to Section
6.7(a)(iv) hereof,

explanation as to such returns made by the party responsible for
payment of such amounts.

                           (b)   Straddle Period: Apportionment of Taxes: In
the case of any Straddle Period, the income taxes of the Foreign
Subsidiaries for the pre-Closing period shall be computed as if such
period ended as of the close of business on the Closing Date, where
applicable.  Any foreign income taxes for a Straddle Period shall be
apportioned between the pre-Closing and the post-Closing period on
the basis of taxable income or taxable loss, as determined from an
interim closing (solely for tax purposes) of the permanent books and
records of the Foreign Subsidiaries, effective as of the close of
business on the Closing Date.

                           (c)   Straddle Period: Filing of Returns: Any
income tax returns of the Foreign Subsidiaries for a Straddle Period

if that period were a separate taxable period, and shall provide
Sellers with its calculations used to arrive at that amount.  Sellers
shall remit to Purchasers the amount of such income tax allocable to
Sellers pursuant to Section 6.7(b) hereof for such period for such
income tax return equal to the excess of. (i) the amount of such
income tax allocable to Sellers; over (ii) amounts previously paid
or provided for through estimated income taxes or deposits paid by
or on behalf of the Foreign Subsidiaries with respect to such income
tax for such period.  Sellers shall pay such amounts no later than
fifteen (15) business days following its receipt of a notice from
Purchasers.

                           (d)   Section 338(h)(10) Election: Sellers and
Purchasers mutually agree to make an election under Section
338(h)(10) of the Code (and any comparable election under state or
local law) with respect to PSG.  Purchasers and Sellers agree that

the retained assets and the retained liabilities of PSG as follows:
(1) real property at values to be determined by the appraisal
conducted pursuant to Section 4.13 hereof; (2) all other tangible and
intangible assets at net book value at the Closing Date; and (3) any
excess to goodwill.  The Purchasers, Sellers and PSG shall file all
Tax Returns in a manner consistent with such values.

                           (e)   Tax Sharing Agreements: Any Tax sharing
agreement between Sellers and any of PSG and the Foreign Subsidiaries
and any similar arrangements shall be and hereby are terminated as

<PAGE>
for any taxable year, whether the current year, a future year, or a
past year.

                           (f)   Further Agreements:   Sellers will notify
Purchasers of any settlement reached under any audit of Sellers'

                           (a)   Third Party Claims: If the claim is for
indemnification with respect to any action, suit, proceeding or
demand at any time instituted or asserted against, or made upon, the
Claimant by or on behalf of a third party (a "Third Party Claim"),
the Claimant will give prompt written notice to the Indemnitor of the
institution, assertion or making of the Third Party Claim, and the
nature thereof.  Upon such notice being given the claim specified
herein shall be deemed to have been made for purposes of this
Agreement.  The Indemnitor shall, within ten (10) days after receipt
of such notice, give written notice to the Claimant as to whether or
not the Indemnitor accepts the responsibility to indemnify Claimant
with respect to the Third Party Claim.  If the Indemnitor accepts the
responsibility to indemnify the Claimant with respect to the Third
Party Claim, the Claimant will then grant to the Indemnitor
authority, and the Indemnitor will proceed, at its sole expense, to
cure, defend, compromise or settle the Third Party Claim, in the name
of the Claimant or otherwise; provided, however, that any such
defense of the Third Party Claim shall be conducted by counsel
reasonably satisfactory to the Claimant, and that the Indemnitor
shall not enter into any final compromise or settlement of the Third
Party Claim without the prior written consent of Claimant.  If the
Indemnitor denies the responsibility to indemnify the Claimant with
respect to the Third Party Claim, or if the Indemnitor fails to
respond in a timely manner to Claimant's notice of the Third Party
Claim or fails to proceed in a diligent and timely manner to cure,
defend, compromise or settle a Third Party Claim for which it has
accepted responsibility pursuant to the foregoing provisions, the
Claimant may then proceed to cure, defend, compromise or settle



                                           55


<PAGE>
such Third Party Claim as it shall in its sole discretion deem to be
advisable, without prejudice to any right to indemnification Claimant
may have against the Indemnitor with respect thereto, whether
pursuant to this Agreement or otherwise, and in such event the
liability of the Indemnitor to the Claimant for indemnification with
respect to such Third Party Claim shall be determined by a final and
nonappealable judgment entered by a court of competent jurisdiction,
or by written consent of the Indemnitor.

                           (b)   Non-Third Party Claims: If the claim is for
indemnification with respect to a matter other than a Third Party
Claim, the Claimant will give prompt written notice to the Indemnitor
of such claim, setting forth with reasonable particularity the basis,
nature and dollar amount thereof.  Upon such notice being given the
claim specified therein shall be deemed to have been made for
purposes of this Agreement.  The Indemnitor shall, within thirty (30)
days after receipt of such notice, give written notice to the
Claimant as to whether or not the Indemnitor accepts the
responsibility to indemnify Claimant with respect to such claim.  If
the Indemnitor accepts the responsibility to indemnify the Claimant
with respect to such claim, the Indemnitor shall immediately pay to
the Claimant the amount set forth in the notice thereof, with such
payment to be made in immediately available funds, and upon actual
receipt of such payment by the Claimant such claim shall be deemed
to have been satisfied.  If the Indemnitor denies the responsibility
to indemnify the Claimant with respect to such claim, or if the
Indemnitor fails to respond in a timely manner to notice of such
claim, the liability of the Indemnitor to the Claimant for
indemnification with respect to such claim shall be determined by
arbitration as provided under Section 10.10 hereof

                    9.4    Certain Indemnification Limitations:
Notwithstanding the foregoing, neither Purchasers Indemnitees nor
Sellers Indemnitees shall be entitled to indemnification from Sellers
or Purchasers, respectively, pursuant to Sections 9.1 (a) through (e)
hereof or Sections 9.2(a) through (h) hereof for any Losses covered
thereunder until such time as the aggregate of all such Losses
incurred by Purchasers Indemnitees or Sellers Indemnitees,
respectively, exceed $350,000.  From and after such time, Purchasers
Indemnitees or Sellers Indemnitees, respectively, shall be entitled
to indemnification pursuant to Sections 9.1 or 9.2 hereof for all
Losses covered thereunder (other than such first $350,000 of Losses). 
Notwithstanding the foregoing, Purchasers Indemnitees shall be
entitled to any indemnification from Sellers pursuant to Section
9.2(i) hereof to the extent of any and all Losses covered thereunder
without regard to such threshold.  In no event whatsoever shall the
total indemnification obligations hereunder exceed the Aggregate
Purchase Price plus or minus the Cash Settlement Adjustment.

                    9.5    Customer Contracts/Receivables Indemnification:

                           (a)   Sequa, Chromalloy and ARC hereby agree that
they shall, jointly and severally, indemnify, protect and make
Purchasers, PSG and the Foreign Subsidiaries whole from and against
the inability to collect Closing Date Receivables as a result of:

                                 (1)    the inaccuracy or falsehood of any
representation, or the breach of any warranty, by ARC, Chromalloy or
Sequa contained in Section 3.2(a) hereof or Schedule 3.2(a) of the
Disclosure Package or in Section 3.2(r)(3) or (4) hereof or in
Schedule 3.2(r) of the Disclosure Package that relates to the
collectibility of Receivables reflected on the Balance Sheet (any
such inaccuracy, falsehood or breach, a "Receivables Breach");

                                 (2)    the inaccuracy or falsehood of any
representation, or the breach of any warranty, by ARC, Chromalloy or
Sequa contained in Section 3.2(s) hereof or Schedule 3.2(s) of the
Disclosure Package to the extent that the effect of such is upon the
collectability of Closing Date Receivables, (any such inaccuracy,
falsehood or breach, a "Disallowance Event"); or

                                 (3)    incurrence by PSG or the Foreign
Subsidiaries prior to the Closing Date of costs after written notice
has been received by PSG or the Foreign Subsidiaries by a U.S.
Government or Foreign Government contracting officer to discontinue
the work, but only to the extent the Uncollectible Receivables relate
to costs incurred after such written notice is received and then,
only prior to the Closing Date (a "Disallowance Event").

                           (b)   Notwithstanding the foregoing, Purchasers,
PSG and the Foreign Subsidiaries shall not be entitled to
indemnification and payment from Sellers pursuant to Section 9.5(a)
hereof for the failure to collect any Closing Date Receivables as a
result of any Receivables Breach or Disallowance Event until the
aggregate amount of all Uncollectible Receivables exceeds $3,417,068
(the "Receivables Allowance").  If the aggregate amount of
Uncollectible Receivables exceeds the Receivables Allowance as a
result of either a Receivables Breach or Disallowance Event, then
Purchasers, PSG and the Foreign Subsidiaries shall be entitled to
indemnification and payment pursuant to Section 9.5(a) hereof for all
Uncollectible Receivables covered thereunder other than such first
$3,417,068 of Uncollectible Receivables.

                           (c)   In the event that any of the Purchasers, PSG
or any of the Foreign Subsidiaries invoke their or its rights to be
indemnified and paid for and recover the amount of any Uncollectible
Receivables by and from Sellers, the following procedures shall be
used:

Sellers (a "Receivables Notice") not later than thirty (30) days
after each second quarter-end and each year-end after the Closing
Date, which shall: (i) identify the Receivables Breach and/or the
Disallowance Event(s) giving rise to such Uncollectible Receivables;
(ii) state the amount of the Uncollectible Receivables for which
payment is being sought; (iii) identify the accounts receivable to

the Receivables Notice is given, Sellers may deliver to Purchasers
a written notice contesting all or any portion of the Uncollectible
Receivables for which payment is sought and setting forth the grounds
for such objection.  If Sellers do not contest all or any portion of
the Uncollectible Receivables, Sellers shall pay to Purchasers, PSG
or the Foreign Subsidiaries, as identified in the Receivables Notice,
in immediately available funds on or prior to the last day of such
thirty (30) day period, the amount of Uncollectible Receivables which
Sellers do not contest, to the extent that the amount of such
Uncollectible Receivables and all Uncollectible Receivables exceeds
or has exceeded the Receivables Allowance.

                                 (3)    If Sellers contest all or any portion
of the Uncollectible Receivables identified in any Receivables
Notice, Purchasers may at any time after thirty (30) days from the
date such Receivables Notice was given pursue payment of the
Uncollectible Receivables identified in such Receivables Notice
pursuant to the procedures set forth in Section 10.10 hereof, without
regard to paragraph (a) thereof.  Sellers shall within thirty (30)
days following the date that any Uncollectible Receivables are
determined pursuant to such procedures in Section 10.10 hereof to be
payable, pay to Purchasers, PSG or the Foreign Subsidiaries, as
identified in the Receivables Notice, in immediately available funds,
the amount of the Uncollectible Receivables determined to be payable,
together with interest thereon at the Applicable Rate from the date
that the Receivables Notice was given until the day before such
amount is paid.

                           (d)   With respect to any Closing Date Receivables
for which Sellers have made payment to Purchasers, Purchasers shall
within fifteen (15) business days of such payment assign all of their

and obligation of either Sellers or Purchasers to provide

counterclaim and the like which are reasonably available to the
Claimant, and federal or state income or franchise tax benefits or

result of the event giving rise to the claim for indemnification. 
In addition, in determining the net amount of such Losses for which
indemnification is required, the amount of indemnification shall be
increased to include any federal or state or franchise tax liability
incurred or reasonably expected to be incurred by a party as a direct
result of such indemnification.  If any tax benefit expected to be
is in fact not realized, or any tax liability expected to be incurred
is not in fact incurred, then an adjustment shall be made to
compensate the other party.

by the Purchasers and Sellers hereunder shall be effected by payment

                10.10    Dispute Resolution:

                        (a)    With respect to any dispute between the
parties relating in any way to this Agreement or the rights and
obligations of the parties hereunder, a party shall first give notice
as provided in Section 10.5 hereof to the other party of the nature
of the dispute setting forth in reasonable detail the facts and
circumstances and the basis for its claim.  The promptly endeavor in
good faith to resolve the dispute.

                        (b)    In the event that within twenty (20) business
days after notice of a dispute is given a resolution is not reached
under paragraph (a) above, the dispute shall, at the written request
of any party involved in the dispute, be submitted for consideration
to an executive officer of CSC and an executive officer of Sequa for
resolution (hereinafter, the "Mediators").  Until notice is otherwise
given by CSC, Lawrence Parkus shall serve as the Mediator designated
by CSC for such purpose.  Until notice is otherwise given by Sequa,
John J. Dowling, III shall serve as the Mediator designated by Sequa
for such purpose.  On a date selected by the Mediators, which date
shall not be later than ten (10) business days after the date from
which they have both received such notice, the Mediators shall meet
at PSG's home office or at such other location agreed upon by the
Mediators, and each interested party shall have up to one hour to
present to the Mediators information relating to the dispute.  Within
ten (10) business days after such date, the Mediators shall confer
and propose a resolution of the dispute.  If the Mediators are unable
to agree upon a resolution of the dispute, then such dispute shall
be settled by binding arbitration to be held in Washington, D.C., in
accordance with the Expedited Procedures of the Commercial
Arbitration Rules of the American Arbitration Association (the
"Arbitration Rules").  Nothing presented to the designated executive
officers, nor the fact of such presentation, shall preclude the full
review of such dispute, and of any incidental matters, in such
arbitration proceedings.  In addition, however, the Arbitrator may
require the parties to produce documents, exhibits, witnesses or
other evidence and the failure of a party to produce such evidence
may be considered adversely to the party so failing to produce the
evidence.  Notwithstanding the foregoing, nothing in this Agreement
shall preclude any party from seeking injunctive relief from a court
with regard to any breach of this Agreement.

                          (c)   The arbitration shall be held before a panel
of one arbitrator selected by the parties who need not be on any
panel of the AAA and who is knowledgeable and experienced in the
field that is the subject of the dispute (including without
limitation in the filed of government contract procedures if the
subject involves a government contract) and is mutually agreeable to
the parties.  In the event that the parties are unable to agree upon
an arbitrator within thirty (30) days after the request for



                                           63

arbitration, such arbitrator shall be designated by the American
Arbitration Association in accordance with the Arbitration Rules upon
the request of any party hereto.

                                 (d) An arbitration may be commenced by any
party to this Agreement by the service of a written Request for
Arbitration upon the other affected parties.  Such Request for
Arbitration shall summarize the controversy or claim to be
arbitrated, and shall be referred by the complaining party to the
American Arbitration Association ten (10) days following such service
or thereafter.  No Request for Arbitration shall be valid if it
relates to a claim, dispute, disagreement or controversy that would
have been time barred under the applicable statute of limitations had
such claim, dispute, disagreement or controversy been submitted to
the appropriate court in the State of New York.

                                (e) The arbitrator shall render his award
within thirty (30) days after the date of closing the oral hearings
or, if oral hearings have been waived, within thirty (30) days after
the date the final statements and proofs are transmitted to the
arbitrator.  The parties hereby agree to be bound by the decision of
the arbitrator, which shall be final and unappealable.  The party or
parties against whom the arbitration decision is made shall bear all
fees and expenses of the arbitrator and of the prevailing party in
such arbitration (including fees and expenses of counsel).  Judgment
upon any award of the arbitrator (including an award of equitable
relief) may be entered in any court having jurisdiction or an
application may be made to such court for the judicial acceptance of
the award and an order of enforcement.  Should any party hereto fail
to appear or be represented at the arbitration proceedings after due
notice in accordance with the Arbitration Rules, then the arbitrator
may nevertheless render a decision in the absence of that party, such
a decision shall have the same force and effect as if the absent
party had been present.

                                (f) It is intended that controversies or
claims submitted to arbitration under this Section shall remain
confidential, and to that end it is agreed by the parties that
neither the facts disclosed in the arbitration, the issues
arbitrated, nor the views or opinions of any persons concerning them,
shall be disclosed to third persons at any time, except to the extent
necessary to enforce an award or judgment or as required by law or
in response to legal process or in connection with such arbitration.

Agreement will be executed by the parties hereto, and each fully
executed counterpart shall be deemed an original without production
of the other.

hereto of a breach of or a default under any of the provisions of
this Agreement, nor the failure of any of the parties, on one or more
occasions, to enforce any of the provisions of this Agreement or to
exercise any right or privilege hereunder shall thereafter be
construed as a waiver of any subsequent breach or default of a

                                                                 Annex 2
                                                                 Page 2 of 5

               (b)   certificates of even date herewith of the corporate
                     secretary of the Purchasers as to corporate
                     resolutions in respect of the Agreement  and the
                     transactions contemplated thereby,  incumbencies of
                     certain officers and a copy of the Restated Articles
                     of Incorporation and By-laws of the Purchasers in
                     effect on a the date hereof;

               (c)   certificates of recent date of the Secretary of
                     State of the State of Nevada and the Companies 
                     House of the United Kingdom as the legal existence
                     and good standing of the Purchasers under the laws
                     of the on State of Nevada and the United Kingdom;
                     and
               (d)   letter dated November 29, 1993 from the Federal 
                     Trade Commission to CSC.

        I have also made such documentary, factual and legal
examinations as I deemed necessary under the circumstances.  As to
factual matters, I have relied with your permission upon statements,
certificates and other assurances of public officials and of officers
and other representatives of Purchasers and upon the representations
and warranties of Purchasers contained in the Agreement (other than
those that state a legal conclusion), without independent
verification.  I have also assumed, among other things, the
genuineness of all signatures, the legal capacity of all natural
persons, the authenticity of all documents submitted to us as
originals, and the conformity to original documents of all documents
submitted to us as copies and the authenticity of the originals of
such copied documents.

        On the basis of the foregoing examination, and in reliance
thereon, and subject to the assumptions, qualifications, limitations
and exceptions set forth herein, I am of the opinion that:

        1.     Organization and Existence:  CSC is a corporation duly
organized, validly existing, and in good standing under the laws of
the State of Nevada and is duly qualified to do business as a foreign
corporation in all other states necessary for the consummation of the
transactions contemplated by the Agreement.  Enterprises is a
corporation duly organized, validly existing, and in good standing
under the laws of the State of Nevada and is duly qualified to do

qualified to do business in each jurisdiction necessary for the
consumunation of the transactions contemplated by the Agreement.

                                                                 Page 3 of 5

        2.     Power and Authority:   CSC, Enterprises and Consulting
have full corporate power and authoritv to execute deliver and
perform the Agreement and the Other Agreements.

        3.     Authorization:   The execution, delivery and
performance of the Agreement and the Other Agreements by
Purchasers have been duly authorized by all requisite corporate
action.

        4.     Binding Effect:   The Agreement and the Other  
Agreements constitute the valid, binding and legal obligations of
Purchasers enforceable against Purchasers in accordance with the
terms hereof and thereof, except as the enforceability hereof and
thereof may be subject to the effect of (i) any applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting creditors rights generally, and (ii)
general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

        5.     No Default:      Neither the execution and delivery of the
Agreement or the Other Agreements nor the performance by
Purchasers of any or all of their obligations hereunder or
thereunder (i) violate or breach, or with the giving of notice or
the passage of time or both, will violate or breach, or otherwise
constitute or give rise to a default under, the terms or
provisions of Purchasers' Articles of Incorporation or By-Laws or
of any material contract, commitment, or other obligation to which
any of the Purchasers is a parry or by which any of them or any of
their property is bound; (ii) require the consent of any party to
any material contract or other agreement to which any of the
Purchasers is a party by which any of them or any of their
property is bound; or (iii) violate any laws, orders, injunctions
or decreases to which any of the Purchasers or any of their
property is subject.

        6.     HSR Filing:      A notification has been filed with the
Federal Trade Commission under the HSR Act, such filings comply as
to form with the HSR Act and the rules and regulations thereunder
and, based upon notice from the Federal Trade Commission to the
Company dated November 29, 1993, the waiting period under the HSR
Act has expired and the Purchasers have received no notice from
the Federal Trade Commission, the U.S. Department of Justice, or
any other person raising any objection under the HSR Act to any of

                                                                 Page 4 of 5

        7.     Regulatory Approvals:           All consents, approvals,
authorizations and other requirements prescribed by any law,
regulation or rule which must be obtained or satisfied by
Purchasers and which are necessary for the execution and delivery
by Purchasers of the Agreement and all other documents and the
consummation of the transactions contemplated in the Agreement
have been obtained or satisfied.

        8.     Litigation:      To the best of my knowledge there is no
judgment, order writ, injunction or decree of any federal, state,
local or foreign court or governmental agency to which Purchasers,
their business, or assets are subject that could affect their
ability to perform their respective obligations under the
Agreement.

        I am admitted to the practice of law before the United
States Supreme Court and several lower federal courts as well as
the state courts of Kansas, Pennsylvania and the District of
Columbia.  My opinion with respect to foreign qualifications
contained in numbered paragraph 1 is based solely upon a review of
unofficial compilations of the provisions of the statutory laws of
the relevant jurisdictions.  I expressly disclaim any obligation
or undertaking to update or modify the opinion as a consequence of
any future changes in the applicable laws or in the facts bearing
upon the opinion.

        I call to your attention that I am not admitted to the
practice of law in the state of Nevada or in the United Kingdom;
however I am familiar with the General Corporation Law of the
State of Nevada and have made such inquiries as I consider
necessary to render the opinions expressed herein with respect to
the General Corporation Law of the State of Nevada and the United
Kingdom.

        This opinion is limited to the effect of the present state
of the General Corporation Law of the State of Nevada and the
United Kingdom and the laws of the relevant jurisdictions, to the
extent set forth in the preceding two paragraphs.  In rendering
the opinion, I assume no obligation to revise or supplement this
opinion should the present laws, or the interpretation thereof, be
changed.
