              OF THE CONSTITUENT CORPORATIONS

          SECTION 2.1. Effect on Capital Stock. As of the
Effective Time, by virtue of the Merger and without any
action on the part of the holder of (i) any shares of common
stock, par value $.01 per share, of the Company (the "Common
Stock"), (ii) any shares of Class A Common Stock, par value
$.01 per share, of the Company (the "Class A Common Stock"),
(iii) any shares of Class B Common Stock, par value $.01 per
share, of the Company (the "Class B Common Stock" and
collectively with the Common Stock and the Class A Common

                       Page 11 of 70
                 Exhibit Index is on page 4

<PAGE>

Stock, the "Company Common Stock") or (iv) any shares of
capital stock of Sub:

          (a) Common Stock of Sub. Each share of common
stock of Sub issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without
any action on the part of the holder thereof, be converted
into one share of common stock of the Surviving Corporation.

          (b) Cancellation of Treasury Stock and
Parent-Owned Common Stock. Each share of any class of
Company Common Stock issued and outstanding immediately
prior to the Effective Time that is owned by the Company or
by any Subsidiary of the Company or by Parent, Sub or any
other Subsidiary of Parent (other than shares in trust
accounts, managed accounts, custodial accounts and the like
that are beneficially owned by third parties), shall
automatically be cancelled and retired and shall cease to
exist, and no cash or other consideration shall be delivered
or deliverable in exchange therefor.

          (c) Conversion of Common Stock. Each share of any
class of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares
to be cancelled in accordance with Section 2.1(b) and other
than Dissenting Common Shares) shall be converted into the
right to receive $42.50 per share net to the holder in cash,
without interest, minus the Per Share Transaction Fees (as
defined in Section 2.4(b)) (the "Merger Consideration").

          (d) Dissenting Shares. Notwithstanding anything in
this Agreement to the contrary, shares of any class of
Company Common Stock issued and outstanding immediately
prior to the Effective Time held by a holder (if any) who
has the right to demand, and who properly demands, an
appraisal of such shares in accordance with Section 262 of
the DGCL (or any successor provision) ("Dissenting Common
Shares") shall not be converted into or represent the right
to receive the Merger Consideration unless such holder fails
to perfect, withdraws or otherwise loses such holder's right
to such appraisal, if any. If, after the Effective Time,
such holder fails to perfect, withdraws or loses any such
right to appraisal pursuant to the DGCL, each such share of
such holder shall be treated as a share that had been
converted as of the Effective Time into the right to receive
the Merger Consideration in accordance with this Section
2.1. The Company shall give prompt notice to Parent of any
demands received by the Company for appraisal of

                       Page 12 of 70
                 Exhibit Index is on page 4

<PAGE>



shares of any class of Company Common Stock, and Parent
shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands.
The Company shall not, except with the prior written consent
of Parent, make any payment with respect to, or settle or
offer to settle, any such demands.

          (e) Cancellation and Retirement of Company Common
Stock. As of the Effective Time, all certificates
representing shares of any class of Company Common Stock,
other than certificates representing shares to be cancelled
in accordance with Section 2.1(b) or Dissenting Common
Shares, issued and outstanding immediately prior to the
Effective Time, shall no longer be outstanding and shall
automatically be cancelled and retired and shall cease to
exist, and each holder of a certificate representing any
such shares of Company Common Stock shall cease to have any
rights with respect thereto, except the right to receive the
Merger Consideration upon surrender of such certificate in
accordance with Section 2.5.

          SECTION 2.2. Stock Options. The Company shall take
such action in order that, at the Effective Time, the
options granted under the Company's Employee Stock Option
Plan or any other stock option plan, agreement or
arrangement (collectively, as such plans, agreements or
arrangements may have been amended, supplemented or modified
from time to time, the "Stock Option Plans") that are
unexercised, whether or not then exercisable (the
"Options"), shall be extinguished by virtue of the Merger
and converted into the right to receive, for each share of
Company Common Stock subject to such Option, an amount in
cash equal to the excess, if any, of the Merger
Consideration for such share over the per share exercise
price of such Option (such excess being referred to as the
"Option Consideration"), and such amount less the amount of
any required withholding taxes shall be paid to the holder
of such Option. The surrender of an Option in exchange for
the Option Consideration shall constitute a release of any
and all rights the holder had or may have had in the Option.
Except as set forth in Section 2.2 of the Disclosure
Schedule, all Stock Option Plans shall terminate as of the
Effective Time and the provisions in any other plan, program
or arrangement providing for the issuance or grant of any
other interest in respect of the capital stock of the
Company or any Subsidiary shall be deleted as of the
Effective Time, and the Company shall take all action
necessary to ensure that, following the Effective Time, no
participant in any Stock Option Plan shall have any right

                       Page 13 of 70
                 Exhibit Index is on page 4

<PAGE>

thereunder to acquire equity securities of the Company, the
Surviving Corporation or any Subsidiary thereof and to
terminate all such plans.

          SECTION 2.3. Warrants. The Company shall take such
action in order that, at the Effective Time, the Company's
warrants to purchase Common Stock issued pursuant to that
certain Warrant Agreement, dated as of April 19, 1994,
between the Company and Shawmut Bank Connecticut, National
Association (the "Warrant Agreement") that are unexercised
(the "Warrants"), shall become exercisable, upon surrender
of such Warrant, for the Merger Consideration (the Merger
Consideration, less the per share exercise price of such
Warrant, being referred to as the "Warrant Consideration").
The surrender of a Warrant in exchange for the Warrant
Consideration shall constitute a release of any and all
rights the holder had or may have had in the Warrant.

          SECTION 2.4. Funds Provided by Parent. (a) Paying
Agent. As of the Effective Time and after taking into
account any amounts paid by the Company pursuant to Section
2.4(b), (i) Parent shall deposit, or shall cause to be
deposited, with or for the account of a bank or trust
company designated by Parent, which shall be reasonably
satisfactory to the Company (the "Paying Agent"), for the
benefit of the holders of shares of each class of Company
Common Stock and the holders of the Warrants, cash in an
amount sufficient to pay the aggregate Merger Consideration
and the aggregate Warrant Consideration (such amount being
hereinafter referred to as the "Payment Fund"), (ii) Parent
shall pay, or shall cause to be paid, to the Company an
amount equal to the aggregate Option Consideration and (iii)
the Company shall pay to each holder of Options the amount
required to be paid to such holder in respect of such
Options as provided in Section 2.2.

          (b) Aggregate Payment. The aggregate amount of
funds to be provided by Parent to pay the Merger
Consideration, the Option Consideration and the Warrant
Consideration (collectively, the "Consideration") pursuant
to Section 2.4(a) is $486,000,000, less the Transaction Fees
(as defined in Section 3.1(l)). In addition, the Company
shall pay to the Paying Agent for deposit into the Payment
Fund or to holders of Options, as the case may be, as of the
Effective Time an amount equal to the aggregate amount
received by the Company pursuant to the exercise of Warrants
or Options during the period from the date hereof to but not
including the Effective Time. For purposes of this

Agreement, "Per Share Transaction Fees" means an amount
equal to (i) the amount of Transaction Fees divided by
(ii) the aggregate number of shares of each class of Company
Common Stock with respect to which any Consideration is to
be paid pursuant to this Article II (whether held directly
or subject to an Option or Warrant).

          SECTION 2.5. Exchange Procedures. (a) (i) Subject
to subparagraph (ii) below, as soon as practicable after the
Effective Time, each holder of an outstanding certificate or
certificates which prior thereto represented shares of any
class of Company Common Stock shall, upon surrender to the
Paying Agent of such certificate or certificates and
acceptance thereof by the Paying Agent, be entitled to the
amount of cash which the aggregate number of shares of such
class of Company Common Stock previously represented by such
certificate or certificates surrendered shall have been
converted into the right to receive pursuant to Section
2.1(c). As soon as practicable after the Effective Time,
each holder of an outstanding Warrant shall, upon surrender
to the Paying Agent of such Warrant and acceptance thereof
by the Paying Agent, be entitled to the amount of cash which
such holder shall have the right to receive pursuant to
Section 2.3. The Paying Agent shall accept such certificates
or Warrants, as the case may be, upon compliance with such
reasonable terms and conditions as the Paying Agent may
impose to effect an orderly exchange thereof in accordance
with normal exchange practices. If the consideration to be
paid in the Merger (or any portion thereof) is to be
delivered to any person (as defined in Section 8.3) other
than the person in whose name the certificate representing
shares of such class of Company Common Stock or Warrant, as
the case may be, surrendered in exchange therefor is
registered, it shall be a condition to such exchange that
the certificate or Warrant so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and
that the person requesting such exchange shall pay to the
Paying Agent any transfer or other taxes required by reason
of the payment of such consideration to a person other than
the registered holder of the certificate or Warrant, as the
case may be, surrendered, or shall establish to the
satisfaction of the Paying Agent that such tax has been paid
or is not applicable. After the Effective Time, there shall
be no further transfer on the records of the Company or its
transfer agent of certificates representing shares of any
class of Company Common Stock and if such certificates are
presented to the Company for transfer, they shall be
cancelled against delivery of the Merger Consideration as

                       Page 15 of 70
                 Exhibit Index is on page 4

hereinabove provided.  Until surrendered as contemplated by
this Section 2.5(a)(i), each certificate representing shares
of any class of Company Common Stock (other than
certificates representing shares to be cancelled in
accordance with Section 2.1(b) or Dissenting Common Shares)
shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the
Merger Consideration, without any interest thereon, as
contemplated by Section 2.1.  No interest will be paid or
will accrue on any cash payable as Merger Consideration or
Warrant Consideration.

          (ii) Notwithstanding Section 2.5(a)(i) above and
Section 2.5(b) below, commencing at any time after the
selection of the Paying Agent in accordance with Section
2.4(a) and any time thereafter prior to payment by the
Paying Agent in accordance with the terms of this Agreement,
each holder of an outstanding certificate or certificates
which, if presented prior to the Effective Time, represents
shares of any class of Company Common Stock or, if presented
after the Effective Time, represented shares of any class of
Company Common Stock, may surrender to the Paying Agent (at
its designated office) such certificate or certificates,
which certificates, if presented prior to the Effective
Time, shall be held in escrow for such stockholders until
the Effective Time by the Paying Agent. Upon such surrender
and acceptance thereof by the Paying Agent in accordance
with the terms set forth in this Agreement, the Paying Agent
shall make payment, on or prior to the next business day
(which in no event shall be prior to the Effective Time),
via wire transfer in immediately available funds to the
account designated in writing by such stockholder, of an
amount equal to the product of (x) the aggregate number of
shares of such class of Company Common Stock previously
represented by such certificate or certificates so
surrendered and (y) the Merger Consideration.

          (b) Letter of Transmittal. Promptly after the
Effective Time (but in no event more than five days
thereafter), the Surviving Corporation shall require the
Paying Agent to mail to each record holder of Warrants and
certificates, other than a holder of certificates that
previously surrendered such certificates in accordance with
Section 2.5(a)(ii), that immediately prior to the Effective
Time represented shares of any class of Company Common Stock
which shall have been converted pursuant to Section 2.1, a
form of letter of transmittal and instructions for use in
surrendering such Warrant or certificates, as the case may

                       Page 16 of 70
                 Exhibit Index is on page 4

<PAGE>

be, and receiving the consideration to which such holder
shall be entitled therefor pursuant to Section 2.3 or 2.1,
as the case, may be.

          (c) No Further Ownership Rights in Company Common
Stock. The Consideration paid upon the surrender for
exchange of certificates representing shares of any class of
Company Common Stock, Options and Warrants thereon, as the
case may be, in accordance with the terms of this Article II
shall be deemed to have been issued and paid in full
satisfaction of all rights pertaining to the shares of such
class of Company Common Stock theretofore represented by
such certificates, or such Options or Warrants, as the case
may be.

          (d) Termination of Payment Fund. Any portion of
the Payment Fund which remains undistributed to the holders
of the certificates representing shares of any class of
Company Common Stock or the Warrants for 120 days after the
Effective Time shall be delivered to the Surviving
Corporation, upon demand, and any holders of shares of any
class of Company Common Stock who theretofore have not
complied with this Article II or holders of Warrants that
have not exercised their rights set forth in Section 2.3
thereafter shall look only to the Surviving Corporation and
only as general creditors thereof for payment of their claim
for any Merger Consideration or Warrant Consideration, as
the case may be.

          (e) No Liability. None of Parent, Sub, the
Surviving Corporation or the Paying Agent shall be liable to
any person in respect of any distributions payable from the
Payment Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If
any certificates representing shares of any class of Company
Common Stock shall not have been surrendered prior to five
years after the Effective Time (or immediately prior to such
earlier date on which any Merger Consideration in respect of
such certificate would otherwise escheat to or become the
property of any Governmental Entity (as defined in Section
3.1(c))), any such distributions payable in respect of such
certificate shall, to the extent permitted by applicable
law, become the property of the Surviving Corporation, free
and clear of all claims or interest of any person previously
entitled thereto.

          (f) Investment of Payment Fund. The Paying Agent
shall invest the Payment Fund, as directed by Parent, in (i)
direct obligations of the United States of America

                       Page 17 of 70
                 Exhibit Index is on page 4

<PAGE>

and (ii) obligations for which the full faith and credit of
the United States of America is pledged to provide for the
payment of principal and interest, and any net earnings with
respect thereto shall be paid to Parent as and when
requested by Parent; provided, however, that any such
investment or any such payment of earnings shall not delay
the receipt of the Merger Consideration by holders of shares
of any class of Company Common Stock or the Warrant
Consideration by holders of the Warrants, as the case may
be, or otherwise impair such holders' respective rights
hereunder.  In the event the Payment Fund shall realize a
loss on any such investment, Parent shall promptly
thereafter deposit in such Payment Fund on behalf of the
Surviving Corporation cash in an amount sufficient to enable
such Payment Fund to satisfy all remaining obligations
originally contemplated to be paid out of such Payment Fund.


                        ARTICLE III

               REPRESENTATIONS AND WARRANTIES

          SECTION 3.1. Representations and Warranties of the
Company. The Company represents and warrants to Parent and
Sub as follows:

               (a) Organization, Standing and Corporate
Power. Each of the Company and each Subsidiary of the
Company (as hereinafter defined) is a corporation duly
organized, validly existing and in good standing under the
laws of the jurisdiction in which it is incorporated and has
the requisite corporate power and authority to own, lease
and operate its properties and to carry on its business as
now being conducted. Each of the Company and each Subsidiary
of the Company is duly qualified or licensed to do business
and is in good standing in each jurisdiction in which the
nature of its business or the ownership or leasing of its
properties makes such qualification or licensing necessary,
other than in such jurisdictions where the failure to be so
qualified or licensed (individually or in the aggregate)
would not have a Material Adverse Effect (as defined in
Section 8.3) with respect to the Company. The Company and
each Subsidiary of the Company has delivered or made
available on or prior to August 22, 1995 to Parent complete
and correct copies of its Charter and By-laws, as amended to
the date of this Agreement.

               (b) Capital Structure. The authorized capital
stock of the Company consists of 13,300,000 shares

                       Page 18 of 70

of Common Stock, 750,000 shares of Class A Common Stock and
750,000 shares of Class B Common Stock.  As of the date
hereof:  (i) 9,347,350 shares of Common Stock were issued
and outstanding, 1,245,375 shares of Common Stock were
reserved for issuance upon exercise of outstanding Options
(in each case at an exercise price of $4.00 per share),
257,493 shares of Common Stock were reserved for issuance
upon exercise of the Warrants (in each case at an exercise
price of $8.00 per share) and 17,500 shares of Common Stock
were held by the Company in its treasury;
(ii) 750,000 shares of Class A Common Stock were issued and
outstanding; and (iii) all shares of Class B Common Stock
were reserved for issuance upon conversion of the Class A
Common Stock.  Except as set forth above, as of the date
hereof, no shares of capital stock or other equity
securities of the Company were issued, reserved for issuance
or outstanding.  Except as set forth in Section 3.1(b)(1) of
the Disclosure Schedule, all outstanding shares of capital
stock of the Company are, and all shares which may be issued
pursuant to the Stock Option Plans or the Warrants will be,
when issued, duly authorized, validly issued, fully paid and
nonassessable and not subject to preemptive rights.  No
bonds, debentures, notes or other indebtedness of the
Company or any Subsidiary of the Company having the right to
vote (or convertible into, or exchangeable for, securities
having the right to vote) on any matters on which the
stockholders of the Company or any Subsidiary of the Company
may vote are issued or outstanding.  All of the outstanding
shares of capital stock or quotas, as the case may be, of
each Material Subsidiary (as defined in Section 8.3) are
owned, directly or indirectly, by the Company, except with
respect to certain shares issued as directors' qualifying
shares.  All the outstanding shares of capital stock or
quotas, as the case may be, of each Material Subsidiary have
been validly issued, are fully paid and nonassessable and
are free and clear of all pledges, claims, liens, charges,
restrictions, encumbrances and security interests of any
kind or nature whatsoever (collectively, "Liens"), except
with respect to certain shares pledged as collateral
pursuant to (A) that certain Pledge Agreement, dated as of
April 19, 1994, between the Company and Shawmut Bank
Connecticut, National Association, entered into in
connection with the Company's issuance of its 11-1/2%
Series B Senior Secured Discount Debentures due 2004 (the

party thereto and Chase Manhattan Bank (National
Association), as administrative agent for such financial
institutions.  Except as set forth in Section 3.1(b)(2) of
the Disclosure Schedule and other than with respect to
directors' qualifying shares, neither the Company nor any
Subsidiary of the Company is a party to or is bound by
(x) any outstanding or authorized option, warrant, call,
subscription or other right, agreement or commitment which
obligates the Company or any Subsidiary of the Company to
issue, deliver, sell or transfer, purchase, redeem or
otherwise acquire, or cause to be issued, delivered, sold or
transferred, purchased, redeemed or otherwise acquired, any
shares of the capital stock or other voting securities
(including voting debt securities) of the Company or any
Subsidiary of the Company, or which obligates the Company or
any Subsidiary of the Company to grant, extend or enter into
any such option, warrant, call, subscription, right,
commitment or agreement, or (y) any shareholder agreements,
voting trusts or other agreements or understandings relating
to the voting of any shares of capital stock or other voting
securities (including voting debt securities) of the Company
or any Subsidiary of the Company.  Section 3.1(b)(2) of the
Disclosure Schedule sets forth a true and complete list of
the Subsidiaries of the Company.  Except for the capital
stock of its Subsidiaries or as otherwise set forth on
Section 3.1(b)(2) of the Disclosure Schedule, the Company
does not own, directly or indirectly, any capital stock or
other ownership interest in any corporation, partnership,
joint venture or other entity.

               (c) Authority; Noncontravention. The Company
has the requisite corporate power and authority to enter
into this Agreement and to consummate the transactions
contemplated by this Agreement. The execution and delivery
of this Agreement by the Company and the consummation by the
Company of the transactions contemplated hereby have been
duly authorized by all necessary corporate action on the
part of the Company. This Agreement has been duly executed
and delivered by the Company and, assuming this Agreement
constitutes the valid and binding agreement of Parent and
Sub, constitutes a valid and binding obligation of the
Company, enforceable against the Company in accordance with
its terms. To the Company's knowledge, no state takeover
statute or similar statute or regulation applies or purports
to apply to this Agreement, the Stockholders Agreement or
any of the transactions contemplated hereby or thereby. The
execution and delivery of this Agreement do not, and the
consummation of the transactions contemplated by this

default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation
or acceleration of any obligation or loss of a material
benefit under, or require the consent of any person under,
(x) any indenture or other agreement, permit, concession,
franchise, license, mortgage, lease, Benefit Plan (as
defined in Section 3.1(h)) or similar obligation, instrument
or undertaking to which the Company or any of its
Subsidiaries is a party or by which the Company or any of
its Subsidiaries or any of their assets is bound or affected
or (y) any credit agreement or similar obligation,
instrument or undertaking to which the Company or any
Material Subsidiary is a party or by which the Company or
any Material Subsidiary or any of their assets is bound or
affected, or (iii) subject to the governmental filings and
other matters referred to in the following sentence,
contravene any law, rule, regulation, order, writ, judgment,
injunction, decree, determination or award, domestic or
foreign, applicable to the Company or any of its
Subsidiaries or their respective properties or assets,
which, in the case of clauses (ii) and (iii) above, would
have a Material Adverse Effect with respect to the Company.
No consent, approval, order or authorization of, or
registration, declaration or filing with, or notice to, any
court, governmental agency or regulatory authority, domestic
or foreign (a "Governmental Entity"), which has not been
received or made, is required by or with respect to the

to beneficial ownership of real property, if any, by the
Company or any of its Subsidiaries, (E) such other consents,
approvals, authorizations, filings or notices as are set
forth in Section 3.1(c)(E) of the Disclosure Schedule and
(F) any applicable filings under state anti-takeover laws,
or filings, authorizations, consents or approvals the
failure to make or obtain which would not have a Material
Adverse Effect with respect to the Company.

               (d) SEC Documents. (i) Each of the Company
and OSi Inc. has filed with the SEC all reports, schedules,
forms, statements and other documents required to be filed

are hereinafter referred to as the "SEC Documents"); and
(ii) as of their respective dates, the SEC Documents
complied in all material respects with the requirements of
the Securities Act of 1933, as amended (the "Securities

rules and regulations of the SEC promulgated thereunder
applicable to such SEC Documents, and none of the SEC
Documents when filed contained any untrue statement of a
material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under
which they were made, not misleading. Except to the extent
that information contained in any SEC Document has been
revised or superseded by a Filed SEC Document (as defined in
Section 3.1(f)), none of the SEC Documents contains any
untrue statement of a material fact or omits to state any

circumstances under which they were made, not misleading.

               (e) Financial Statements. (i) The audited

               (f) Absence of Certain Changes or Events; No
Undisclosed Material Liabilities. Except as disclosed in the
SEC Documents filed and publicly available prior to the date
of this Agreement (the "Filed SEC Documents") or in Section

the Company and its Subsidiaries have conducted their

not been (i) any change which would have a Material Adverse
Effect with respect to the Company, (ii) any declaration,

(iii) any split, combination or reclassification of any of

agreements by the Company to do any of the things described
in the preceding clauses (i) through (vii) other than as
expressly contemplated or provided for herein.  Except as
set forth in the most recent Filed SEC Document, as of the
date of this Agreement there are no material liabilities or
obligations of the Company or any of its Subsidiaries of any
kind whatsoever, whether accrued, contingent, absolute,
determined, determinable or otherwise, that would otherwise
have been required by applicable law or by generally
accepted accounting principles to be disclosed in such Filed
SEC Document had it arisen prior to the date of such Filed
SEC Document.

               (g) Absence of Changes in Benefit Plans.

               (h) Employee Benefit Plans. Section 3.1(h) of
the Disclosure Schedule identifies each employee benefit
plan (as that phrase is defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended
("ERISA")) and any other benefit or compensation plan,
program or arrangement maintained, administered or
contributed to by the Company or any ERISA Affiliate (as
defined in Section 8.3) for the benefit of any current or
former employee, officer or director of the Company or any
of its Subsidiaries (the "Benefit Plans"). The Company has
delivered or made available to Parent on or prior to August
22, 1995 true, complete, correct and current copies of (w)
each Benefit Plan (or, in the case of any unwritten Benefit
Plans, true, complete, correct and current descriptions
thereof), (x) the most recent annual report on Form 5500
filed with the Internal Revenue Service with respect to each
Benefit Plan (if any such report was required), (y) the most

Company or any Material Subsidiary for which such summary
plan description is required and (z) each currently
effective trust agreement and insurance or group annuity
contract, including related actuarial report, relating to
any Benefit Plan of the Company or any Material Subsidiary.
The information furnished by the Company to the actuary in
connection with the preparation of each actuarial report in
clause (z) above was complete and accurate in all material
respects, and the Company has no reason to believe that any
conclusion in any such actuarial report is inaccurate.

          Except as set forth in Section 3.1(h) of the
Disclosure Schedule, with respect to the Benefit Plans of
the Company and the Material Subsidiaries:

               (i) none of such Benefit Plans is a
"multiemployer plan" within the meaning of Section 3(37) of
ERISA;

              (ii) none of such Benefit Plans is subject to
Title IV of ERISA ("Pension Plans");

             (iii) none of such Benefit Plans promises or
provides retiree medical or life insurance benefits to any
person, including through any organization described in
Section 501(c)(9) of the Code;

              (iv) no employee of the Company or any
Material Subsidiary will be entitled to additional benefits,
increase of a benefit amount, the payment of a contingent

                       Page 25 of 70
                 Exhibit Index is on page 4

<PAGE>

benefit, or the acceleration of the payment or vesting of a
benefit by reason of the execution of this Agreement or the
consummation of the transactions contemplated by this
Agreement;

               (v) each such Benefit Plan intended to be
qualified under Section 401(a) of the Code has received a
favorable determination letter from the IRS that it is so
qualified and nothing has occurred since the date of such
letter that could reasonably be expected to affect the
qualified status of such Benefit Plan;

              (vi) each such Benefit Plan has been
administered in all material respects in accordance with its
terms and the Company, each Material Subsidiary (with
respect to their respective duties and obligations under
each of such Benefit Plans) and such Benefit Plans are in
compliance in all material respects with applicable
provisions of ERISA, the Code and any other applicable law,
and there are no investigations by any Governmental Entity,
termination proceedings or other claims (except claims for
benefits payable in the normal operation of such Benefit
Plans), suits or proceedings against or involving any such
Benefit Plan or asserting any rights or claims to benefits
under any such Benefit Plan that could give rise to any
material liability, and there are not any facts that could

          SECTION 3.2. Representations and Warranties of
Parent and Sub. Parent and Sub represent and warrant to the
Company as follows:

               (a) Organization, Standing and Corporate
Power. Each of Parent and Sub is a corporation duly
organized, validly existing and in good standing under the
laws of the jurisdiction in which it is incorporated and has
the requisite corporate power and authority to own, lease
and operate its properties and to carry on its business as
now being conducted. Each of Parent and Sub is duly
qualified or licensed to do business and is in good standing
in each jurisdiction in which the nature of its business or
the ownership or leasing of its properties makes such
qualification or licensing necessary, other than in such
jurisdictions where the failure to be so qualified or
licensed (individually or in the aggregate) would not have a
Material Adverse Effect with respect to Parent. Parent has
delivered, and Sub will deliver, to the Company complete and
correct copies of their Certificates of Incorporation and
By-laws, as amended to the date of this Agreement.

               (b) Authority; Noncontravention. Parent and
Sub have all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions
contemplated by this Agreement. The execution and delivery
of this Agreement by Parent and Sub and the consummation by
Parent and Sub of the transactions contemplated by this
Agreement have been duly authorized by all necessary
corporate action on the part of Parent and Sub and by
Parent, as the sole stockholder of Sub. This Agreement has
been duly executed and delivered by and, assuming this
Agreement constitutes the valid and binding agreement of the
Company, constitutes a valid and binding obligation of each
of Parent and Sub, enforceable against such party in
accordance with its terms. The execution and delivery of
this Agreement do not, and the consummation of the
transactions contemplated by this Agreement and compliance
with the provisions of this Agreement will not, (i) conflict
with any of the provisions of the Certificates of
Incorporation or By-laws of Parent or the Certificate of
Incorporation or By-laws of Sub, (ii) subject to the
governmental filings and other matters referred to in the
following sentence, conflict with, result in a breach of or
default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation
or acceleration of any obligation or loss of a material
benefit under, or require the consent of any person under,
any indenture, or other agreement, permit, concession,

                       Page 38 of 70
                 Exhibit Index is on page 4

<PAGE>

franchise, license, credit agreement, mortgage, lease,
employee benefit plan or similar obligation, instrument or
undertaking to which Parent or any of its subsidiaries is a
party or by which Parent or any of its subsidiaries or any
of their assets is bound or affected, or (iii) subject to
the governmental filings and other matters referred to in
the following sentence, contravene any law, rule,
regulation, order, writ, judgment, injunction, decree,
determination or award, domestic or foreign, applicable to
Parent or Sub or their respective properties or assets
which, in the case of clauses (ii) and (iii) above, would
have a Material Adverse Effect with respect to Parent.  No
consent, approval, order or authorization of, or
registration, declaration or filing with, or notice to, any
Governmental Entity which has not been received or made is
required by or with respect to Parent or Sub in connection
with the execution and delivery of this Agreement by Parent
or Sub or the consummation by Parent or Sub, as the case may
be, of any of the transactions contemplated by this
Agreement, except for (A) the filing of premerger
notification and report forms under the HSR Act with respect
to the Merger, (B) the filing with the SEC of such reports
under the Exchange Act as may be required in connection with
this Agreement and the transactions contemplated hereby, (C)
the filing of the Certificate of Merger with the Delaware
Secretary of State, and appropriate documents with the
relevant authorities of other states in which the Company is
qualified to do business, (D) such other consents,
approvals, authorizations, filings or notices as are set
forth in Section 3.1(c)(E) of the Disclosure Schedule and
(E) any applicable filings under state antitakeover laws, or
filings, authorizations, consents or approvals the failure
to make or obtain which, in the aggregate, would not have a
Material Adverse Effect with respect to Parent.

               (c) Voting Requirements. No vote of the
holders of the shares of any class or series of capital
stock of Parent is necessary to approve this Agreement or
consummate the transactions contemplated by this Agreement.

               (d) No Prior Activities. Sub has not
incurred, and will not incur, directly or through any
Subsidiary, any liabilities or obligations for borrowed
money or otherwise, except incidental liabilities or
obligations not for borrowed money incurred in connection
with its organization and except in connection with
obtaining financing in connection with the Merger. Except as
contemplated by this Agreement, Sub (i) has not engaged,
directly or through any Subsidiary, in any business

                       Page 39 of 70

<PAGE>

activities of any type or kind whatsoever, (ii) has not
entered into any agreements or arrangements with any person
and (iii) is not subject to or bound by any obligation or
undertaking.

               (e) Brokers. No broker, investment banker,
financial advisor or other person, other than J.P. Morgan &
Co. Incorporated and The Chase Manhattan Bank, N.A., the
fees and expenses of which will be paid by Parent, is
entitled to any broker's, finder's, financial advisor's or
other similar fee or commission in connection with the
transactions contemplated by this Agreement based upon
arrangements made by or on behalf of Parent.

               (f) Financing. The Parent has access to funds
necessary to consummate the Merger and the transactions
contemplated thereby, and to pay all related fees and
expenses.

               (g) Employee Benefit Plans. Parent intends to
cause the Surviving Corporation and its Subsidiaries to
maintain for a period of two years following the Effective
Time employee benefit plans, arrangements or policies (other
than stock based plans) which provide benefits to employees
of the Surviving Corporation and its Subsidiaries that are
comparable in the aggregate to those currently provided by
the Benefit Plans. Thereafter, Parent intends to maintain
health and welfare plans which provide benefits to such
employees that are at least comparable in the aggregate to
those enjoyed by similarly situated employees of Parent or
its relevant foreign subsidiaries.

                         ARTICLE V

                   ADDITIONAL AGREEMENTS

          SECTION 5.1. Access to Information;
Confidentiality. The Company shall, and shall cause each of
its Subsidiaries to, afford to Parent and to the officers,
employees, counsel, financial advisors and other
representatives of Parent reasonable access during normal
business hours during the period prior to the Effective Time
to all its properties, books, contracts, commitments,
personnel and records and, during such period, the Company
shall, and shall cause each of its Subsidiaries to, furnish
as promptly as practicable to Parent such information
concerning its business, properties, financial condition,
operations and personnel as Parent may from time to time
reasonably request. Parent will hold, and will cause its
respective directors, officers, partners, employees,
accountants, counsel, financial advisors and other
representatives and affiliates (as defined in Section 8.3)
to hold, any information obtained from the Company in
confidence in accordance with the provisions of the

                       Page 44 of 70
                 Exhibit Index is on page 4

<PAGE>

confidentiality agreement previously entered into between
Parent and the Company.

          SECTION 5.2. Commercially Reasonable Best Efforts.
Upon the terms and subject to the conditions and other
agreements set forth in this Agreement, each of the parties
agrees to use its commercially reasonable best efforts to
take, or cause to be taken, all actions, and to do, or cause
to be done, and to assist and cooperate with the other
parties in doing, all things necessary, proper or advisable
to consummate and make effective, in the most expeditious
manner practicable, the Merger and the other transactions
contemplated by this Agreement, including the satisfaction
of the respective conditions set forth in Article VI.

          SECTION 5.3. Indemnification and Insurance. Parent
and Sub agree that all rights to indemnification and
exculpation from liability for acts or omissions occurring
prior to the Effective Time now existing in favor of the
current or former directors or officers of the Company and
its Subsidiaries as provided in their respective
certificates of incorporation or by-laws shall survive the
Merger and shall continue in full force and effect in
accordance with their terms (whether or not actually amended
pursuant to Section 1.5(b) or otherwise) for a period of not
less than six years from the Effective Time. Parent shall
cause to be maintained for a period of three years from the
Effective Time the Company's current directors' and
officers' insurance and indemnification policy to the extent
that it provides coverage for events occurring prior to the
Effective Time (the "D&O Insurance") for all persons who are
directors or officers of the Company or any Subsidiary on
the date of this Agreement, so long as the annual premium
therefor would not be in excess of 175% of the last annual
premium paid prior to the date of this Agreement (175% of
such premium, the "Maximum Premium"); provided, however,
that Parent may, in lieu of maintaining such existing D&O
Insurance as provided above, cause comparable coverage to be
provided under any policy maintained for the benefit of the
directors and officers of Parent or any of its Subsidiaries,
so long as (i) the issuer thereof has at least an equal
claims-paying ability and (ii) the material terms thereof
are no less advantageous than the existing D&O Insurance to
the extent commercially available. If the existing D&O
Insurance expires, is terminated or cancelled during such
three-year period, Parent will use all reasonable efforts to
cause to be obtained as much D&O Insurance as can be
obtained for the remainder of such

                 Exhibit Index is on page 4

<PAGE>

period for an annualized premium not in excess of the
Maximum Premium, on terms and conditions no less
advantageous than the existing D&O Insurance to the extent
commercially available.  The Company represents to Parent
that the Maximum Premium is $341,250.

          SECTION 5.4. Public Announcements. Parent and Sub,
on the one hand, and the Company, on the other hand, will
consult with each other before issuing, and provide each
other the opportunity to review and comment upon, any press
release or other public statements with respect to the
transactions contemplated by this Agreement, including the
Merger, and shall not issue any such press release or make
any such public statement prior to such consultation, except
as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any
national securities exchange.

          SECTION 5.5. Acquisition Proposals. The Company,
its Subsidiaries and their respective officers, directors,
employees, representatives, agents or affiliates (including
any investment banker, attorney or accountant retained by
the Company or any of its Subsidiaries) (collectively, the
"Company Representatives") shall immediately cease any
discussions or negotiations with any person other than
Parent that may be ongoing with respect to an Acquisition
Proposal (as defined below). From and after the date hereof
until the termination of this Agreement, the Company shall
not, nor shall it permit any of its Subsidiaries or Company
Representatives to, directly or indirectly, (i) solicit,
initiate or encourage the submission of any Acquisition
Proposal or (ii) participate in any discussions or
negotiations regarding, or furnish to any person any
information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal. Notwithstanding anything in this
Agreement to the contrary, the Company shall promptly advise
Parent orally (within one business day), and at any time
after five days after the date of this Agreement, in writing
(as promptly as practicable) of the receipt by it (or any of
the other entities or persons referred to above) after the
date hereof of any Acquisition Proposal or any inquiry which
is intended to lead to any Acquisition Proposal. The Company
will keep Parent fully informed orally (within one business
day) and in writing (as promptly as practicable) of all the
relevant details of any such Acquisition Proposal or
inquiry. For purposes of this Agreement, "Acquisition
Proposal" means any proposal with respect to a merger,

consolidation, share exchange or similar transaction
involving the Company or any Material Subsidiary, or any
purchase of all or any significant portion of the assets of
the Company or any Material Subsidiary, or any equity
interest in the Company or any Material Subsidiary, other
than the transactions contemplated hereby.  Notwithstanding
the foregoing, the Company may take and disclose to its
stockholders a position contemplated by Rule 14e-2(a)
promulgated under the Exchange Act and may make any
disclosure to the Company's stockholders which, in the good
faith judgment of the Board of Directors of the Company
based on the advice of its legal advisors, may be required
under applicable law.

          SECTION 5.6. Consents, Approvals and Filings. (a)
The Company and Parent will make and cause their respective
Subsidiaries to make all necessary filings, as soon as
practicable, including those required under the HSR Act, the
Securities Act and the Exchange Act in order to facilitate
prompt consummation of the Merger and the other transactions
contemplated by this Agreement. In addition, the Company and
Parent will each use their commercially reasonable best
efforts, and will cooperate fully with each other (i) to

requirements applicable to the Merger and the other
transactions contemplated by this Agreement and (ii) to

consents of all third parties necessary for the consummation
of the Merger and the other transactions contemplated by
this Agreement. Each of the Company and Parent shall use
commercially reasonable best efforts to provide such
information and communications to Governmental Entities as
such Governmental Entities may reasonably request.

               (b) Each of the parties shall provide to the
other party copies of all applications in advance of filing
or submission of such applications to Governmental Entities
in connection with this Agreement.

          SECTION 5.7. Special Severance Arrangements. The
Severance Benefit Plan for Employees of OSi Specialties

               employment (other than for cause);

     cause) within one year after the Effective Time.

Except as provided above, employees of the Company or its
Subsidiaries whose employment is terminated after the
Effective Time shall be entitled to severance benefits in
accordance with Parent's then applicable severance policies.

Government Entity shall have issued an order, decree or

on the part of a party to any such extension or waiver shall
be valid only if set forth in an instrument in writing

                         STOCKHOLDERS AGREEMENT dated as of
                    September 10, 1995, among WITCO
                    CORPORATION, a Delaware corporation
                    ("Parent"), OSI SPECIALTIES HOLDING
                    COMPANY, a Delaware corporation (the
                    "Company"), and the other parties
                    signatory hereto (each, a
                    "Stockholder").


          WHEREAS each Stockholder desires that the Company,
Parent and Witsil Corporation, a Delaware corporation and
wholly owned subsidiary of Parent ("Sub"), enter into an
Agreement and Plan of Merger dated the date hereof (as the
same may be amended or supplemented, the "Merger Agreement")
with respect to the merger of Sub with and into the Company
(the "Merger"); and

          WHEREAS each Stockholder and the Company are
executing this Agreement as an inducement to Parent to enter
into and execute, and to cause Sub to enter into and
execute, the Merger Agreement;


          NOW, THEREFORE, in consideration of the execution
and delivery by Parent and Sub of the Merger Agreement and
the mutual covenants, conditions and agreements contained
herein and therein, the parties agree as follows:

          1. Representations and Warranties. Each
Stockholder severally represents and warrants to Parent as
follows:

          (a) Such Stockholder is the record and beneficial
owner of, or is trustee of a trust that is the record holder
of, and whose beneficiaries are the beneficial owners of,
the number of shares of Company Common Stock set forth
opposite such Stockholder's name in Schedule A hereto (such
Stockholder's "Shares"). Except for such Stockholder's
Shares and any other shares of Company Common Stock subject
hereto, such Stockholder is not the record or beneficial
owner of any shares of Company Common Stock. This Agreement
has been duly authorized, executed and delivered by, and
constitutes a valid and binding agreement of, such
Stockholder, enforceable in accordance with its terms.

                       Page 58 of 70
                 Exhibit Index is on page 4

<PAGE>


          (b) Neither the execution and delivery of this
Agreement nor the consummation by such Stockholder of the
transactions contemplated hereby will result in a violation
of, or a default under, or conflict with, any contract,
trust, commitment, agreement, understanding, arrangement or
restriction of any kind to which such Stockholder is a party
or is bound or to which such Stockholder's Shares are
subject. No trust of which such Stockholder is a trustee
requires the consent of any beneficiary to the execution and
delivery of this Agreement or to the consummation of the
transactions contemplated hereby. If such Stockholder is
married and such Stockholder's Shares constitute community
property, this Agreement has been duly authorized, executed
and delivered by, and constitutes a valid and binding
agreement of, such Stockholder's spouse, enforceable against
such person in accordance with its terms. Consummation by
such Stockholder of the transactions contemplated hereby
will not violate, or require any consent, approval, or
notice under, any provision of any judgment, order, decree,
statute, law, rule or regulation applicable to such
Stockholder or such Stockholder's Shares, except for any
necessary filing under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976.

          (c) Such Stockholder's Shares and the certificates
representing such Shares are now and at all times during the
term hereof will be held by such Stockholder, by a nominee
or custodian for the benefit of such Stockholder or by a
permitted transferee, free and clear of all liens, claims,
security interests, proxies, voting trusts or agreements,
understandings or arrangements or any other encumbrances
whatsoever, except for any such encumbrances or proxies
arising hereunder or under the existing terms of a trust of
which such Stockholder is the trustee.

          (d) No broker, investment banker, financial
adviser or other person is entitled to any broker's,
finder's, financial adviser's or other similar fee or
commission payable by the Company in connection with the
transactions contemplated hereby based upon arrangements
made by or on behalf of such Stockholder.

          (e) Such Stockholder understands and acknowledges
that Parent is entering into, and causing Sub to enter into,
the Merger Agreement in reliance upon such Stockholder's
execution and delivery of this Agreement.

          2. Voting Agreements. Each Stockholder severally
agrees with, and covenants to, Parent as follows:

          (a) At any meeting of stockholders of the Company
called to vote upon the Merger and the Merger Agreement or
at any adjournment thereof or in any other circumstances
upon which a vote, consent or other approval with respect to
the Merger and the Merger Agreement is sought, such
Stockholder shall vote (or cause to be voted) such
Stockholder's Shares in favor of the Merger, the execution
and delivery by the Company of the Merger Agreement and the
approval of the terms thereof and each of the other
transactions contemplated by the Merger Agreement, provided
that the terms of the Merger Agreement shall not have been
amended to adversely affect the Stockholder.

          (b) At any meeting of stockholders of the Company
or at any adjournment thereof or in any other circumstances
upon which their vote, consent or other approval is sought,
such Stockholder shall vote (or cause to be voted) such
Stockholder's Shares against (i) any merger agreement or
merger (other than the Merger Agreement and the Merger),
consolidation, combination, sale of substantial assets,
reorganization, recapitalization, dissolution, liquidation
or winding up of or by the Company or (ii) any amendment of
the Company's Certificate of Incorporation or By-laws or
other proposal or transaction involving the Company or any
of its subsidiaries which amendment or other proposal or
transaction would in any manner impede, frustrate, prevent
or nullify the Merger, the Merger Agreement or any of the
other transactions contemplated by the Merger Agreement
(each of the foregoing in clause (i) or (ii) above, a
"Competing Transaction").

          3. Covenants. Each Stockholder severally agrees
with, and covenants to, Parent as follows:

          (a) Such Stockholder shall not (i) transfer (which
term shall include, without limitation, for the purposes of
this Agreement, any sale, gift, pledge or other
disposition), or consent to any transfer of, any or all of
such Stockholder's Shares or any interest therein, except
pursuant to the Merger, (ii) enter into any contract, option
or other agreement or understanding with respect to any
transfer of any or all of such Shares or any interest
therein, (iii) grant any proxy, power-of-attorney or other
authorization in or with respect to such Shares, except for
this Agreement, or (iv) deposit such Shares into a voting
trust or enter into a voting agreement or arrangement with

                       Page 60 of 70
                 Exhibit Index is on page 4

<PAGE>

respect to such Shares; provided that any such Stockholder
may transfer (as defined above) any of such Stockholder's
Shares to any other person that is on the date hereof, or
that prior to such transfer becomes pursuant to an express
written agreement, a party to this Agreement bound by all
the obligations of a "Stockholder" hereunder.

          (b) Upon the satisfaction of all the conditions
set forth in the Merger Agreement, such Stockholder's Shares
shall, pursuant to the terms of the Merger Agreement, be
exchanged for the consideration provided in the Merger
Agreement. Such Stockholder hereby waives any rights of
appraisal, or rights to dissent from the Merger, that such
Stockholder may have.

          (c) Such Stockholder shall not, nor shall it
authorize any investment banker, attorney or other adviser
or representative of such Stockholder to, directly or
indirectly, (i) solicit, initiate or encourage the
submission of, any takeover proposal or (ii) participate in
any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other
action to facilitate any inquiries or the making of any
proposal that constitutes, or may reasonably be expected to
lead to, any takeover proposal. Without limiting the
foregoing, it is understood that any violation of the
restrictions set forth in the preceding sentence by an
investment banker, attorney or other adviser or
representative of such Stockholder, whether or not such
person is purporting to act on behalf of such Stockholder or
otherwise, shall be deemed to be in violation of this
Section 3(c) by such Stockholder. For all purposes hereof,
"takeover proposal" means any proposal for a merger or other
business combination involving the Company or any of its
subsidiaries or any proposal or offer to acquire in any
manner, directly or indirectly, an equity interest in any
voting securities of, or a substantial portion of the assets
of the Company or any of its subsidiaries, other than the
Merger and the other transactions contemplated by the Merger
Agreement and other than any transfer expressly permitted by
the proviso to Section 3(a).

          4. Certain Events. Each Stockholder agrees that
this Agreement and the obligations hereunder shall attach to
such Stockholder's Shares and shall be binding upon any
person or entity to which legal or beneficial ownership of
such Shares shall pass, whether by operation of law or
otherwise, including without limitation such Stockholder's
heirs, guardians, administrators or successors. In the

   WITCO SIGNS AGREEMENT TO ACQUIRE OSi SPECIALTIES INC.;
     ANNOUNCES INTENTION TO DIVEST ITS LUBRICANTS GROUP


GREENWICH, CT, September 11, 1995 -- Witco Corporation (NYSE:WIT)
announced today that it has entered into an agreement to acquire OSi
Specialties Inc. ("OSi") from an investor group led by DLJ Merchant
Banking Partners, L.P. through a cash merger transaction which values
100 percent of OSi's equity at $486 million.  The acquisition of OSi has
been approved by OSi's shareholders but remains subject to certain
domestic and foreign regulatory approvals and customary closing
conditions.
     Witco also announced its intention to divest its Lubricants Group.
The Lubricants Group, with 1994 sales of $404 million, comprises three
distinct businesses; (i) Lubricants, including Kendall(R) and Amalic(R)
brand motor oils; (ii) Greases, such as private label greases, fluid
lubricants, and LubriMatic(R) brand lubricants and hand-held grease guns;
and (iii) Golden Bear(TM) naphthenic process oils and road and surface
materials.
     OSi is a leading global producer of organofunctional silane and other
specialty silicone derivative products.  Witco expects OSi to have 1995
sales of $450 million with close to 50 percent of sales outside of the
United States.  The company has over 1250 employees with facilities in
Sistersville and South Charleston, West Virginia; Tarrytown, New York;
and Texas City, Texas; as well as Italy, Belgium, Switzerland, Brazil,
Mexico, South Korea, Singapore, Malaysia, Indonesia, and Thailand.
     William R. Toller, chairman and chief executive officer of Witco
said, "Properties with the product and market fit of OSi are rarely
available and an opportunity such as this is unique.  This acquisition
fits directly in with the strategy of focusing on higher-margin
specialty chemcial businesses which we have been implementing over the
past two years.  We believe that this transaction will be accretive in
1996, provide an excellent platform for Witco's future growth, and will
help deliver value to our shareholders."
     Witco will finance the acquisition with cash-on-hand and available
bank facilities.  It is Witco's intention to replace all or part of such
bank financing in the public markets in due course.
     With the acquisition of OSi and the subsequent divestiture of the
Lubricants Group, Witco will be firmly positioned as a worldwide
specialty chemical company, concentrating its resources on its key
product lines of oleochemicals, petroleum specialties, urethane systems,
surfactants, polymer additives, and silicone derivatives.  Witco is
replacing businesses that have not fit into its existing core portfolio
with higher growth, higher margin specialty chemical businesses.  Each
of OSi's product lines has a customer and an application fit within
Witco's existing product portfolios.  OSi's presence in Asia, South
America, and Eastern Europe will provide the base for acceleration of
growth of Witco's existing products.
     Witco Corporation is a worldwide manufacturer of specialty chemical
and specialty petroleum products with 1994 annual sales in excess of
$2.2 billion.
