Item 2. Acquisition of Assets

On January 12, 1996, Cabletron Systems Acquisition, Inc. ("CS
Acquisition"), a Delaware corporation and a wholly-owned
subsidiary of Cabletron Systems, Inc. (the "Registrant"), a
Delaware corporation, purchased substantially all of the assets
(the "Assets") and certain liabilities of Standard Microsystems
Corporation,  a Delaware corporation, and SMC Enterprise
Networks, Inc., a wholly-owned subsidiary of Standard
Microsystems Corporation and a Delaware corporation (collectively
"SMC") related to SMC's Enterprise Networks switching product
line pursuant to an Asset Purchase Agreement dated January 9,
1996 among the Registrant, CS Acquisition and SMC (the
"Agreement").  SMC's Enterprise Networks switching product line
consists of scalable Fast Ethernet switching products for small,
medium and large networks. The purchase price for the Assets was

Company expects to recognize an after tax expense of
approximately $58 to $68 million ($.80 to $.95 per share) in the
fourth quarter of Fiscal year 1996 for in-process research and
development and acquisition related expenses. The purchase was
funded out of available cash of the Registrant.  The terms of the
sale, including the consideration, were determined by arm's
length negotiations.

Exhibit 7(a)4

Standard Microsystems Corporation and Subsidiaries
Enterprise Networks Business Unit
Notes to Statement of Net Assets and Statement of Revenues and
Expenses Before Corporate Overhead Allocations, Interest and
Income Taxes as of February 28, 1995


(1)  Organization and Basis of Presentation

The Enterprise Networks Business Unit ("ENBU") is an operating
unit of the Systems Products Division (the "Division") of
Standard Microsystems Corporation (the "Company"), whose focus is
the marketing, engineering and development of the Company's local
area network switching products.

In January, 1996, Cabletron Systems, Inc. (Cabletron) entered
into an Asset Purchase Agreement with the Company, under which
the Company sold certain net assets of its local area network
switching products business to Cabletron.  The sales price was
approximately $76 million in cash, subject to certain purchase
price adjustments as defined in the Asset Purchase Agreement.
Through this transaction, Cabletron acquired specific assets and
intellectual properties and assumed certain liabilities directly
related to the ENBU.

The accompanying Statement of Net Assets reflects the historical
carrying values of the assets and liabilities of the Enterprise
Networks Business Unit.  The statement does not include the
income tax accounts or intercompany accounts related to the ENBU.
The accompanying Statement of Revenues and Expenses Before
Corporate Overhead Allocations, Interest and Income taxes
includes the direct costs of the ENBU and an allocation of
certain indirect costs related to the operations of the ENBU.
Such allocations are based upon determinations that management
believes are reasonable.  In connection with its overall
operation, the Company provides certain financial, legal and
professional, human resource, accounting, information systems,
and executive management services to the ENBU.  The accompanying
statements do not include these corporate expenses, interest
expense, interest income or income taxes.  Therefore, the net
operating results before corporate overhead allocations, interest
and income taxes as presented herein may not be representative of
future operating results and are not intended to be a full
presentation of the ENBU's operating results.

All of the cash management functions of the ENBU are performed by
the Company.  As a result, cash receipts for the ENBU are
deposited in the Company's general corporate bank accounts.
Similarly, operating expenses, capital expenditures, corporate
services and other cash requirements of the ENBU are paid by the
Company and charged directly by the Company or allocated to the
ENBU.

(2)  Summary of Significant Accounting Policies

Inventories
Inventories are valued at the lower of first-in, first-out cost
(material, direct labor and overhead) or market.  Raw materials
shared with other product lines within the Company have been
excluded from these financial statements.

Property and Equipment
Property and equipment used directly by the ENBU in marketing and
development of the ENBU products are carried at cost and are
depreciated on a straight-line basis over the estimated useful
lives of the machinery and equipment (3 to 7 years).  Leasehold
improvements are amortized over the remaining life of the lease.
Upon sale or retirement of property and equipment, the related
cost and accumulated depreciation are removed from the respective
accounts and any gain or loss is reflected currently.

Intangible Assets
The excess of acquisition cost over fair value of net assets
acquired in the acquisition of Sigma Network Systems, Inc. is
approximately $7,582,000, net of accumulated amortization of
$2,347,000.  The goodwill is being amortized on a straight-line
basis over an estimated useful life of seven years.

Product Warranty
The Company's products developed by the ENBU are under warranty
against defects in material and workmanship for periods of up to
one year.  Estimated warranty costs are accrued when the products
are sold.

Allocation of Operating Expenses
Included in the accompanying Statement of Revenues and Expenses
Before Corporate Overhead Allocations, Internet and Income Taxes
are direct research and development, marketing, and general and
administrative expenses of the ENBU.  Selling expenses are
generally incurred on a Division-wide basis.  The selling
expenses associated with the North American direct sales force
related to the ENBU have been included in their entirety.
Certain Divisional marketing, general and administrative, sales
administration and international selling expenses have been
allocated based upon the ratio that ENBU revenues represented in
comparison to the Division's total revenues.  The total of such
allocated expenses was approximately $1,400,000 in fiscal 1995.

Use of Estimates
The preparation of the financial statements of the ENBU in
conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial
statements and the reported amounts revenues and expenses during
the period.

Estimated reserves have been recorded for excess and obsolete
inventory and estimated sales returns.  Actual results could
differ from those estimates.

(3)  Other Current Assets

Other current assets consist of the following at February 28, 1995:
(in thousands)

Evaluation inventory, net of reserves                 $800
Security deposits                                      303
Employee loans and advances                            259
Other current assets                                   216
                                                    $1,578

(4)  Accrued Expenses and Other Liabilities

(in thousands)

Accrued compensation and benefits                     $915
Accrued professional fees                              109
Accrued rent                                           137
Accrued royalties                                      106
                                                    $1,267

(5)  Commitments and Contingencies

Operating Lease
The ENBU leases a facility in Andover, Massachusetts that expires
in 2001.  Rent expense for fiscal 1995 was $378,000.  Future
minimum rental each fiscal year under this lease are as follows:

1996          $269,000
1997           386,000
1998           406,000
1999           421,000
2000           436,000
Thereafter     565,000

Litigation
In the ordinary course of business, various lawsuits and claims
are filed against the Company.  While the outcome of these
matters is currently not determinable, management believes that
the ultimate resolution of these matters will not have a material
adverse effect on the Company's operations or financial position.

The Company and wholly-owned subsidiary, SMC Enterprise Networks,
Inc. are currently defendants in litigation claiming breach of
contract and fraud.  Penril Datacomm Networks, Inc. has asserted
that the Company did not honor the terms of a product development
contract, and as a result, has caused them damage through their
inability to enter the backbone switching marketplace and has
asserted damages of approximately $50 million, which it seeks to
treble.  While the Company believes it has meritorious defenses
against the suit, the ultimate resolution of the matter is not
determinable.  The Company has made no accruals with respect to
this litigation.

In June 1995, several actions were filed against the Company and
certain of its directors and officers.  The consolidated claims
purport to be a class action on behalf of the purchasers of the
Company's common stock from September 19, 1994 through June 2,
1995.  The consolidated complaint asserts claims under federal
securities laws, and alleges that the Company artificially
inflated the price of its common stock during the class action
period by false and misleading statements and the failure to
disclose certain information.  The Company intends to vigorously
defend against these claims.

(6)  Compensation Plans

Employees of the ENBU generally participate in various
compensation and benefits plans provided by the Company.  The
Company maintains a defined contribution Incentive Savings and
Retirement Plan (401(k)) which permits employees to contribute up
to 15% of their earnings.  The Company makes contributions equal
to one half of the employees contribution up to to 6%.  The
Company's contribution is invested in its common stock.  the
Company's contribution attributed to employees of the ENBU was
approximately $100,000 in fiscal 1995.  Certain employees of the
ENBU also participate in the Company's stock option plans.

The Company has employment agreements with certain key employees
of the ENBU which provide for the base salaries totaling $600,000
per year through fiscal 1996.  Incentive payments aggregating up
to $830,000 per year are also payable under these contracts
through fiscal 1996, subject to achieving certain product
development and revenue milestones as defined in the contracts.

(7)  Significant Concentrations

Sources of Supply
The ENBU currently utilizes a single sub-contract supplier to
manufacture substantially all of its products.  Although there
are a limited number of sub-contract manufacturers for these
products, management believes that other suppliers could provide
similar products on comparable terms.  A change in suppliers,
however, could cause a delay in manufacturing and a possible loss
of sales, which could adversely effect operating results.

Credit Risk
The ENBU sells most of its products to value added resellers,
original equipment manufacturers and end users and, as a result,
maintains individually significant receivable balances from its
major customers.  The Company performs credit evaluations on a
regular basis and generally requires no collateral.  Allowances
for credit losses are maintained, and actual losses have been
within management's expectations.

Geographic and Customer Information
International sales accounted for 47% of total revenues for the
ENBU during fiscal 1995.  There was a single customer for ENBU
products which represented 13% of the total ENBU revenues.

Pro Forma Adjustments

a.  Purchase price of $76,400 paid out of cash, including acquisition
costs of $500. In-process research and development costs of $63,520
were written off in connection with the acquisition. The fair value
of the acquired technology in process was determined with the help of
an independent appraiser.  The anticipated charge to operations for
such acquired technology in process is excluded from the unaudited
Pro Forma Combined Statements of Operations as it is non-recurring
and unusual and relates directly to the acquisition.
b.  Adjustments of inventory and warranty reserves of $4,000 to
conform to Cabletron's policies.
c.  Elimination of Seller's goodwill of $2,923 and application of
purchase price accounting.
d.  Cabletron's assumption of liabilities of $15,000.
e.  Accrual of (i) like product vendor commitments of $1,000; (ii) 
accrual of manufacturing reorganization and facilities charge of
$2,000; and (iii) accrual of new employees compensation packages of
$3,000.
f.  Tax effect of write off of in process research and development
costs and transaction costs (a) at Cabletron's marginal rate of 39.225%.
g.  Tax effect of (b, d and e).

           Exhibit A hereto.
           
                2.6. Adjustment to Purchase Price; Closing Date
           Audit Closing Date Audit;.  Within 20 days following
           the Closing Date, SMC shall prepare a closing
           statement that shall consist solely of a balance
           sheet of the Assets Acquired and the Assumed
           Liabilities relating to the ENBU as of the Closing
           Date (the "Final Closing Net Assets Acquired
           Statement") prepared consistently with the
           Preliminary Closing Net Assets Acquired Statement
           attached hereto as Schedule 2.6(a) (the "Preliminary
           Closing Net Assets Acquired Statement") and (ii) a
           Final Balance Sheet of the ENBU dated as of the
           Closing Date prepared in accordance with GAAP
           consistently with the Most Recent Balance Sheet (the
           "Final Balance Sheet") and shall deliver them to
           Buyer.  The Final Closing Net Assets Acquired
           Statement shall be derived from the Final Balance
           Sheet and shall specifically describe the derivation
           from such Final Balance Sheet.  Within 30 days of
           receipt of the Final Closing Net Assets Acquired
           Statement, KPMG Peat Marwick will, at Buyer's
           expense, conduct an examination in accordance with
           generally accepted auditing standards or such other
           similar procedures reasonably considered necessary by
           KPMG Peat Marwick (the "Closing Date Audit") of the
           Acquired Assets and Assumed Liabilities as reflected
           on the Final Closing Net Assets Acquired Statement as
           of the close of business on the Closing Date.  SMC
           shall make its work papers and back up materials used
           in preparation of the Final Closing Net Assets
           Acquired Statement and the Final Balance Sheet
           available for review by Buyer and KPMG Peat Marwick.
           Within ten days of the completion of the Closing
           Audit, Buyer shall provide SMC with written notice of
           any adjustments to the Final Closing Net Assets
           Acquired Statement provided to Buyer from SMC
           excluding issues relating to inventory valuation and
           including adjustments to the total amount of accounts
           receivable less accounts payable as reflected on the
           Final Balance Sheet ("Dispute Notice").  If Buyer
           does not provide a Dispute Notice to SMC within such
           10 day period, Buyer shall be deemed to have accepted
           the Final Closing Net Assets Acquired Statement as
           prepared by SMC and shall be final and binding on the
           parties in the absence of fraud or manifest error.
           
                Based upon the Final Balance Sheet as audited
           and as agreed to by the Parties as contemplated by
           this 2.6, (i) Seller will pay to Buyer, within 5
           days of the resolution of such disputes, an amount
           equal to the amount by which (A) the accounts
           receivable less the accounts payable as reflected on
           Final Balance Sheet exceeds (B) $1,900,000 or (ii)
           Buyer will pay Sellers, within 5 days of the
           resolution of such disputes, an amount equal to the
           amount by which (A) the accounts receivable less the
           accounts payable as reflected on Final Balance Sheet
           is less than (B) $1,900,000.  Any other payments that
           may be determined based on the above, shall be made
           by Sellers to Buyer within 5 days of such resolution.
           
                The Dispute Notice shall set forth the amounts
           as to which the Buyer disagrees.  The Parties shall
           attempt in good faith to resolve such dispute.  In
           the event that the Parties cannot so agree, the
           Parties shall, at Sellers' and Buyer's joint expense,
           resolve the dispute by arbitration. The Buyer and
           Sellers have selected Price Waterhouse to resolve any
           remaining objections.  The determination of such
           accounting firm shall be made within 30 days of the
           notification of Price Waterhouse by Buyer and
           Sellers, shall be set forth in writing and shall be
           conclusive and binding on the Parties.  The fees and
           expenses of Price Waterhouse shall be shared equally
           by the Buyer and the SMC.  The Final Closing Net
           Assets Acquired Statement shall be revised to reflect
           the resolutions of any objections thereto.
           
                2.7. The Closing.  The closing of the
           transactions contemplated by this Agreement (the
           "Closing") shall take place at the offices of Ropes &
           Gray in Boston, Massachusetts, commencing at 10:00

           determine (the "Closing Date").

           Sale in the form attached hereto as Exhibit B-2, and

           hereto as Exhibit B-3; (iv) the Sellers will deliver
           copies of all material items among the items
           identified in Section 2.1(h)(ii), identifying in

           will deliver to SMC the consideration payable at
           Closing specified in  2.5 above.
           
                Simultaneously with such delivery, each of the
           Sellers will use its reasonable best efforts and take
           all action as may be necessary to put Buyer and, in

           Assets.

           Closing, at the request of  Buyer and without further
           consideration, except as stated below, any of the
           Sellers: (a) will execute and deliver such other

           and confirmation and take such action as Buyer may
           reasonably determine is necessary to transfer, convey
           and assign to Buyer, and to confirm Buyer's title to
           or interest in the Acquired Assets, to put Buyer in
           actual possession and operating control thereof and
           to assist Buyer in exercising all rights with respect
           thereto; (b) will deliver to Buyer copies of all non-
           material items among the items identified in Section

           The Parties agree that the preliminary allocation of
           the Purchase Price for the Acquired Assets shall be

           reasonable efforts to perform such further
           development of the Joint Software as is currently

           is subject (or result in the imposition of any

           which filings have been made, and except where the
           failure to give notice, to file, or to obtain any
           authorization, consent, or approval would not have a
           material adverse effect on the financial condition of
           the ENBU or on the ability of the Sellers to
           consummate the transactions contemplated by this
           Agreement.
           
                3.5. Brokers' Fees.  None of the Sellers has any
           Liability or obligation to pay any fees or
           commissions to any broker, finder, or agent with
           respect to the transactions contemplated by this
           Agreement for which the Buyer could become liable or
           obligated.
           
                3.6. Title to Assets. The Sellers collectively
           have good and valid title to, or a valid and
           subsisting leasehold interest in, and the power to
           sell the Acquired Assets, free and clear of all
           Security Interests, except for properties and assets
           disposed of in the Ordinary Course of Business since
           November 30, 1995 and not in contravention of
           provisions of 3.11.
           
                3.7. Acquired Assets Used in Business.  The
           Acquired Assets comprise all of the assets,
           properties and rights of every type and description,
           real, personal, tangible and intangible used by the
           ENBU in product development, manufacturing, marketing
           and testing of the Products other than the Excluded
           Assets set forth in  2.2(d) and (e) above.
           
                3.8. Subsidiaries.   3.8 of the Disclosure
           Letter sets forth for the Subsidiary (i) its name and
           jurisdiction of incorporation, (ii) the number of
           shares of authorized capital stock of each class of
           its capital stock, (iii) the number of issued and
           outstanding shares of each class of its capital
           stock, the names of the holders thereof and the
           number of shares held by each such holder, (iv) the
           number of shares of its capital stock held in
           treasury, and (v) its directors and officers.  SMC
           holds of record and owns beneficially all of the
           outstanding shares of the Subsidiary, free and clear
           of any restrictions on transfer, Taxes, Security
           Interests, options, warrants, purchase rights,
           contracts, commitments, equities, claims, and
           demands.
           
                3.9. Financial Statements.  Attached hereto as
           Exhibit D are the following financial statements
           (collectively the "Financial Statements"): (i)
           unaudited balance sheet (statement of net assets and
           liabilities) and an unaudited statement of revenues
           and expenses for the fiscal year ended February 28,
           1995 (the "Most Recent Fiscal Year End") for the
           Acquired Assets and (ii) unaudited Most Recent
           Balance Sheet as of November 30, 1995 and unaudited
           statement of revenues and expenses relating to the
           Acquired Assets for the nine- and three-month periods
           ending November 30, 1995 ("Interim Financial
           Statements").  The Financial Statements have been
           prepared in accordance with GAAP applied on a
           consistent basis throughout the periods covered
           thereby and are consistent with the books and records
           of the ENBU.  The Parties agree that inventory
           reserves for valuation as of the date of the Most
           Recent Balance Sheet are deemed to be adequate.
           
                3.10.     Indebtedness; Guarantees Guarantees;.
           Except as set forth on the Most Recent Balance Sheet,
           none of the Sellers has any indebtedness for money
           borrowed or for the deferred purchase price of
           property or services, excluding trade payables and
           other accrued current liabilities incurred in the
           ordinary course of business, or capital lease
           obligations, conditional sale or other title
           retention agreements relating to the Assets of the
           ENBU ("Indebtedness").  None of the Sellers is a
           guarantor or otherwise liable for any Liability or
           obligation, of any other Person for any matter which
           relates to or affects or will affect the Assets of
           the ENBU.
           
                3.11.     Absence of Changes.  Since the Most
           Recent Balance Sheet date and except as disclosed in
            3.11 of the Disclosure Letter, there has not been
           any material adverse change in the business,
           financial condition, operations or results of
           operations of the ENBU.  Without limiting the
           generality of the foregoing, since that date:
           
                (a)   none of the Sellers has sold, leased,
           transferred, or assigned any of the ENBU's assets,
           tangible or intangible, other than for a fair
           consideration in the Ordinary Course of Business;
           
                (b)   none of the Sellers has entered into (i)
           any agreement, contract, lease, or license (or series
           of related agreements, contracts, leases, and
           licenses) involving payments of more than $25,000
           relating to the Assets of the ENBU or (ii) any
           exclusive distribution agreement or any agreement
           that would limit Buyer's rights to select
           distribution channels for the Products;
           
                (c)  no party (including the ENBU and the
           Sellers) has accelerated, terminated, modified, or
           canceled any agreement, contract, lease, or license
           (or series of related agreements, contracts, leases,
           and licenses) involving payments of more than $25,000
           relating to the Assets of the ENBU;
           
                (d)  none of the Sellers has imposed any
           Security Interest upon any of the ENBU's assets,
           tangible or intangible;
           
                (e)   the ENBU has not made any capital
           expenditure (or series of related capital
           expenditures) involving more than $10,000 singly or
           $50,000 in the aggregate.
           
                (f)   none of  the Sellers has made any capital
           investment in, any loan to, or any acquisition of the
           securities or assets of, any other Person (or series
           of related capital investments, loans, and
           acquisitions) involving payments of more than $25,000
           relating to the Assets of the ENBU;
           
                (g)   the ENBU has not issued any note, bond, or
           other debt security or created, incurred, assumed, or
           guaranteed any indebtedness for borrowed money or
           capitalized lease obligation involving payments of
           more than $25,000;
           
                (h)   the ENBU has not delayed or postponed the
           payment of accounts payable and other Liabilities
           outside the Ordinary Course of Business;
           
                (i)   the ENBU has not canceled, compromised,
           waived, or released any right or claim (or series of
           related rights and claims) involving payments of more
           than $25,000;
           
                (j)   none of the Sellers or the ENBU has
           granted any license or sublicense of any rights under
           or with respect to any Intellectual Property;
           
                (k)   none of the Sellers has any reason to
           believe that its major vendors, licensors,
           distributors and customers do not intend to continue
           with Buyer a business relationship on terms at least
           as favorable as the relationship such vendors,
           licensors, distributors and customers, as the case
           may be, currently have with Sellers.
           
                (l)   the ENBU has not experienced any material
           damage, destruction, or loss (whether or not covered
           by insurance) to its property;
           
                (m)   none of the Sellers has made any loan to,
           or entered into any other transaction with, any of
           the ENBU's directors, officers, and employees outside
           the Ordinary Course of Business;
           
                (n)   none of the Sellers has entered into any
           employment contract or collective bargaining
           agreement, written or oral, or modified the terms of
           any existing such contract or agreement relating to
           the Assets of the ENBU;
           
                (o)   none of the Sellers has granted any
           increase in the base compensation of any of the
           directors, officers, and employees of the ENBU
           outside the Ordinary Course of Business;
           
                (p)   none of the Sellers has adopted, amended,
           modified or terminated any bonus, profit-sharing,
           incentive, severance, or other plan, contract, or
           commitment for the benefit of any of the directors,
           officers, and employees of the ENBU(or taken any such
           action with respect to any other Employee Benefit
           Plan);
           
                (q)   none of the Sellers has made any payment
           pursuant to any Employee Benefit Plan, or bonus,
           profit-sharing, incentive, severance or other plan,
           contract or commitment for the benefit of any of
           ENBU's directors, officers and employees;
           
                (r)   none of the Sellers has changed employment
           terms for any of the directors, officers, and

           Business;
           
                (s)   the ENBU has not made or pledged to make
           any charitable or other capital contribution outside
           the Ordinary Course of Business;
           
                (t)   none of the Sellers or the ENBU has
           modified or changed the application of GAAP from the
           manner in which it was applied in the Financial
           Statements;
           
                (u)   there has not been any other occurrence,
           event, incident, action, failure to act, or
           transaction outside the Ordinary Course of Business
           involving the ENBU; and
           
                (v)   none of the Sellers has accelerated the
           collection or conversion of accounts receivable or
           notes receivable by offering any incentive for such

           discounts, allowances or enhancements; and
           
                (w)   none of the Sellers has committed to do
           any of the foregoing.
           
                3.12.     Absence of Undisclosed Liabilities.
           There is no Liability (and, to the Sellers' knowledge
           without additional investigation there is no Basis
           for any present or future action, suit, proceeding,
           hearing, investigation, charge, complaint, claim, or
           demand against any of them giving rise to any
           Liability) of the ENBU, except for (i) Liabilities
           set forth on the face of the Most Recent Balance
           Sheet (rather than in any notes thereto), (ii)
           Liabilities which have arisen after the date of the
           Most Recent Balance Sheet in the Ordinary Course of
           Business, and (iii) Liabilities not assumed pursuant
           to  2.3.
           
                3.13.     Legal and Other Compliance.  Each of
           the ENBU and its respective predecessors is in
           compliance with all applicable laws (including rules,
           regulations, codes, plans, injunctions, judgments,
           orders, decrees, rulings, and charges thereunder) of
           federal, state, local, and foreign governments (and
           all agencies thereof) the violation of which would
           have a material adverse effect on the ENBU or its
           operations, and no action, suit, proceeding, hearing,
           investigation, charge, complaint, claim, demand, or
           notice has been filed or commenced against any of
           them alleging any failure so to comply.  Neither the
           ownership nor use of the properties of the ENBU,
           excluding Intellectual Property, nor the conduct of
           the business relating to the Assets of the ENBU
           conflicts with the rights of any other Person or
           violates, with or without the giving of notice or the
           passage of time or both, any terms or provisions of
           any Lien or Security Interest, lease, license,
           agreement, understanding, law, ordinance, rule or
           regulation, or any order, judgment or decree to which
           the ENBU is a party or by which they or their assets
           are bound or affected.
           
                3.14.     Taxes.
           
                (a)  Each of the Sellers has timely filed all
           Tax Returns that they were required to file
           concerning the ENBU.  All Taxes owed by the Sellers
           concerning the ENBU (whether or not shown on any Tax
           Return) have been paid.  The Sellers currently are
           not the beneficiary of any extension of time within
           which to file any Tax Return relating to the Assets
           of the ENBU.  No claim has ever been made by an
           authority in a jurisdiction where any of the Sellers
           does not file Tax Returns that they may be subject to
           taxation by that jurisdiction in respect of Assets of
           the ENBU.  There are no Security Interests in any of
           the Assets of the ENBU that arose in connection with
           any failure (or alleged failure) to pay any tax.
           
                (b)  There is no dispute or claim concerning any
           Tax Liability relating to the Assets of the ENBU
           either (A) claimed or raised by any authority in
           writing or (B) as to which the Sellers have Knowledge
           based upon contact with any agent of such authority.
           The federal Tax Returns for SMC and its consolidated
           subsidiaries have been audited for all years from
           February 28, 1988 through February 28, 1993.
           Included in that return were the ENBU operations for
           the short period January 1, 1993 to February 28,
           1993.  No other income Tax Returns filed with respect
           to the ENBU Assets have been audited.  All returns
           filed for periods subsequent to February 28, 1993
           remain open, but are not currently under audit.  Each
           of the Sellers has delivered to the Buyer correct and
           complete copies of all federal Income Tax Returns,
           examination reports and statements of deficiencies
           assessed against or agreed to relating to the Assets
           of the ENBU.
           
                (c)  The unpaid Taxes of the Sellers for the
           business relating to the Assets of the ENBU (A) did
           not, as of the Most Recent Balance Sheet, exceed the
           reserve for Tax Liability (rather than any reserve
           for deferred Taxes established to reflect timing
           differences between book and Tax Income) set forth on
           the face of the Most Recent Balance Sheet (rather
           than in any notes thereto) and (B) do not exceed that
           reserve as adjusted for the passage of time through
           the Closing Date.
           
                (d)  At the Closing, the Sellers will provide
           the Buyer with a certificate substantially in the
           form specified in Treas. Reg. 1.1445-2(b)(2)(iii)(B)
           to the effect that the Sellers are not foreign
           persons for purposes of sections 897 and 1445 of the
           Internal Revenue Code of 1986, as amended.
           
                3.15.     Property, Plant and Equipment.
           
                (a)   None of the Sellers owns any real property
           that is used in the Acquired Assets other than
           incidental assets located at SMC's sites in New York;
           
                (b)  Section 3.15(b) of the Disclosure Letter
           lists all real property leased or subleased to the
           Sellers that is used in the Assets of the ENBU.  The
           Sellers have delivered to the Buyer correct and
           complete copies of the leases and subleases listed in
            3.15(b) which have not been amended or modified
           since the date thereof of the Disclosure Letter (as
           amended to date). With respect to each lease and
           sublease listed in  3.15(b) of the Disclosure
           Letter:
           
                (i) to the Sellers' Knowledge, the lease or
           sublease is legal, valid, binding, enforceable, and
           in full force and effect;
           
                (ii)  to the Sellers' Knowledge, the lease or
           sublease will continue to be in full force and effect
           on identical terms following the consummation of the
           transactions contemplated hereby (including the
           assignments and assumptions referred to in  2
           above);
           
                (iii)  to the Sellers' Knowledge, no party to
           the lease or sublease is in breach or default, and no
           event has occurred which, with notice or lapse of
           time, would constitute a material breach or default
           or permit termination, modification, or acceleration
           thereunder;
           
                (iv)  to the Sellers' Knowledge, no party to the
           lease or sublease has repudiated any provision
           thereof;
           
                (v) none of the Sellers has granted any sublease
           under the lease or sublease;
           
                (vi) none of the Sellers has assigned,
           transferred, conveyed, mortgaged, deeded in trust, or
           encumbered any interest in the leasehold or
           subleasehold; and
           
                (vii)  all facilities leased or subleased
           thereunder have received all approvals of
           governmental authorities (including licenses and
           permits) required in connection with the operation
           thereof and have been operated and maintained in
           accordance with applicable laws, rules, and
           regulations.
           
                (c) All improvements, machinery, equipment and
           other tangible assets which are included in the
           Acquired Assets and used in the development,
           manufacture and testing of the Products are free from
           defects (patent and latent), have been reasonably
           maintained, are in good operating condition and
           repair (subject to normal wear and tear) and are
           suitable in all material respects for the purposes
           for which they presently are used.
           
                3.16.     Intellectual Property.
           
                (a)  To the Seller's Knowledge, the Sellers own
           or have the right to use pursuant to a written
           license or agreement, all Intellectual Property.
           
                (b)  Except as disclosed in  3.16 of the
           Disclosure Letter and except for Patents owned by
           parties other than the Sellers, the Assets of the
           ENBU have not infringed upon or misappropriated any
           intellectual property rights of third parties (and,
           to Sellers' Knowledge, there is no Basis for a claim
           of such infringement or misappropriation), and none
           of the Sellers and the officers (and employees with
           responsibility for Intellectual Property matters at
           the ENBU) of the ENBU has ever received any notice
           alleging any such infringement or misappropriation.
           
                (c)  All of the Sellers' employees that have
           participated in the development of the Products have
           entered into employee agreements with one of the
           Sellers assigning all right, title and interest in
           the Intellectual Property therein to a Seller.
           Pursuant to such employee agreements or applicable
           law, the Sellers own all of the right, title and
           interest of their employees to any Intellectual
           Property in the Products.
           
                (d) Schedule 2.1(d) identifies: (i) certain
           items of Intellectual Property, and (ii) each license
           or agreement which the Sellers have granted to any
           third party with respect to any of the Intellectual
           Property.  With respect to each item of Intellectual
           Property:
           
                (i)  the Sellers own all Intellectual Property
           designated as owned by Sellers, free and clear of any
           Security Interest and are in compliance with all
           material terms of all licenses relating to any
           Intellectual Property licensed to Sellers;
           
                (ii)  the item is not subject to any outstanding
           injunction, judgment, order, decree, ruling, or
           charge;

           investigation, charge, complaint, claim, or demand is
           pending, or to the Knowledge of the Sellers, is
           threatened, which challenges the legality, validity,
           enforceability, use, or ownership of the item, and to
           the Sellers' actual  knowledge without independent
           investigation, there is no Basis therefor; and
           
                (iv)  none of the Sellers has agreed to
           indemnify any Person (other than customers of the
           Sellers or users of the Sellers' products) for or
           against any infringement or misappropriation with
           respect to the item.
           
                (e)  Section 3.16(e) of the Disclosure Letter

           the Acquired Assets which, to the Knowledge of the
           Sellers, is owned by a third party and is used
           pursuant to license or agreement.  The Sellers have
           provided to the Buyer correct and complete copies of
           all such licenses and agreements.  With respect to
           each item of Intellectual Property, except as set
           forth in  3.16(e) of the Disclosure Letter:
           
                (i)  the underlying item of Intellectual

           charge;
           
                (ii)  no action, suit, proceeding, hearing,
           investigation, charge, complaint, claim or demand is
           pending or, to the Knowledge of the Sellers, is
           threatened, which challenges the legality, validity,
           or enforceability of the underlying item of
           Intellectual Property;
           
                (iii)  none of the Sellers or the ENBU has
           granted any sublicense or similar right with respect
           to the license, sublicense, agreement or permission;
           and
           
                (iv)  the license or agreement is legal, valid,
           binding, enforceable, and in full force and effect,
           and, to the Sellers' Knowledge, will continue to be
           legal, valid, binding, enforceable, and in full force
           and effect on identical terms following the
           consummation of the transactions contemplated hereby.
           
                (f)  To the Knowledge of the Sellers, the
           Acquired Assets do not infringe upon any Patents
           owned by parties other than the Sellers.  It is
           expressly understood that for the purposes of this
           Section 3.16(f), the Sellers have not searched any
           patent records and the Sellers do not undertake to
           make a search of any patent records.
           
                (g)  To the Knowledge of the Sellers, no third
           party has infringed upon or misappropriated any
           Intellectual Property.  It is expressly understood
           that for the purposes of this Section 3.16(g), the
           Sellers have not conducted any independent
           investigation intended to reveal any such
           infringement or misappropriation.
           
                3.17.     Inventories.  The inventory of the
           ENBU consists of raw materials and supplies,
           manufactured and purchased parts, goods in process,
           and finished goods, none of which is  damaged, or
           defective, subject only to the reserve for inventory
           writedown set forth on the face of the Most Recent
           Balance Sheet as adjusted for the passage of time
           through the Closing Date in accordance with GAAP and
           the past custom and practice of the Sellers. The
           inventory, taken as a whole, as reflected in the Most
           Recent Balance Sheet   and books and records of the
           ENBU is valued at the lower of cost (on a first-in,
           first-out basis) or market in accordance with GAAP,
           consistently applied.  Since the date of the Most
           Recent Balance Sheet, no inventory has been sold or
           disposed of except through sales in the Ordinary
           Course of Business.  The Parties agree that the
           inventory reserves for valuation as of the date of
           the Most Recent Balance Sheet are deemed to be
           adequate.

           Except as disclosed in  3.18 of the Disclosure
           Letter, with respect to each such material agreement:
           (A) the agreement is legal, valid, and binding and in
           full force and effect; (B) the Sellers are not, and
           to the Sellers' Knowledge, no other party is in
           breach or default, and no event has occurred which

           thereto or reserve therefor) as adjusted for the
           passage of time in accordance with GAAP and past
           practice and custom of the Sellers.
           
                3.20.     Powers of Attorney.  There are no
           outstanding powers of attorney executed on behalf of

           local or foreign laws and regulations, contractual

           of the Sellers or the ENBU has any Liability (and

           suit, proceeding, hearing, investigation, charge,
           complaint, claim, or demand giving rise to any

           prospects nor any arbitration proceeding arising out
           of or under any collective bargaining agreement is
           pending and no pending claims therefore have been
           made.  Except as disclosed in  3.23 of the
           Disclosure Letter, no collective bargaining agreement
           to which the any of the Sellers is a party restricts
           such Seller or the ENBU from relocating, closing or
           subcontracting any of the ENBU's operations.

           the ENBU's current or former directors, officers, or
           employees.

           Benefit Plan which is an Employee Welfare Benefit
           Plan.
           
                (iv)  Each such Employee Benefit Plan which is
           an Employee Pension Plan intended to be qualified
           under 401(a) of the Code is so qualified.
           
                (v)  The Sellers have delivered to the Buyer
           correct and complete copies of the plan documents,
           summary plan descriptions, insurance contracts and

           have been no Prohibited Transactions with respect to
           any Employee Benefit Plan.  None of the Sellers has
           not incurred any Liability to the PBGC (other than
           PBGC premium payments) or otherwise under Title IV of
           ERISA (including any withdrawal Liability) or under
           the Code with respect to any such Employee Benefit
           Plan which is an Employee Pension Benefit Plan.
           
                (c)  None of the Sellers, their Subsidiaries and

           or future retired or terminated employees, their
           spouses, or their dependents (other than in

           hereunder as an Acquired Asset, other than Excluded
           Assets.
           
                3.27.     [Reserved]
           
                3.28.     Distributors, Customers, Suppliers.

           Product.
           
                3.29.     No Illegal Payments, Etc. To the
           Knowledge of the Sellers, none of the Sellers, nor
           any of the officers, employees or agents of the ENBU,

           make any illegal contribution, or reimbursed any
           illegal political gift or contribution made by any
           other person, to any candidate for federal, state,
           local or foreign public office (i) which may subject

           have, individually or in the aggregate, a material
           adverse effect on the ENBU or (b) established or
           maintained any unrecorded fund or asset or made any
           false entries on any books or records for any
           purpose.
           
                3.30.     Books and Records.  The books and all
           corporate (including minute books and stock record
           books) and financial records of the ENBU are complete
           and correct in all material respects and have been
           maintained in accordance with applicable sound
           business practices, laws and other requirements.
           
                3.31.     Consents.  Section 3.31 of the
           Disclosure Letter sets forth a true, correct and
           complete list of the identities of any Person whose
           consent or approval is required and the matter,
           agreement or contract to which such consent relates
           in connection with the transfer, assignment or
           conveyance by the Sellers of any of the Acquired
           Assets.
           
                3.32.     Disclosure.  Neither the
           representations and warranties contained in this  3
           (including the Disclosure Letter) nor any certificate
           furnished or to be furnished by Sellers to Buyer
           contains any untrue statement of a material fact or
           omit to state any material fact necessary in order to
           make the statements and information contained in this
            3 not misleading.  There is no material fact known
           to the Sellers relating to the ENBU or the Acquired
           Assets which may materially adversely affect the same
           which has not been disclosed in writing in this
           Agreement to the Buyer. Notwithstanding the foregoing
           sentence, the Sellers make no representation as to
           the future financial performance of the business
           relating to the Assets of the ENBU.
           
           4.   Representations and Warranties of Cabletron and
           Acquisition.  The Buyer represents and warrants to
           each of the Sellers that the statements contained in
           this  4 are correct and complete as of the date of
           this Agreement and, if different than the date of
           this Agreement, will be correct and complete as of
           the Closing Date (as though made then and as though
           the Closing Date were substituted for the date of
           this Agreement throughout this  4).
           
                4.1. Organization of Cabletron and Acquisition.
           Each of Cabletron and Acquisition is a corporation
           duly organized, validly existing, and in good
           standing under the laws of the jurisdiction of its
           incorporation.
           
                4.2. Authority for Agreement.  Each of Cabletron
           and Acquisition has full power and authority
           (including full corporate power and authority) to
           execute and deliver this Agreement and to perform its
           obligations hereunder.  This Agreement constitutes
           the valid and legally binding obligation of each of
           Cabletron and Acquisition, enforceable in accordance
           with its terms and conditions.
           
                4.3. Noncontravention.  Neither the execution
           and the delivery of this Agreement, nor the
           consummation of the transactions contemplated hereby
           (including the assignments and assumptions referred
           to in  2 above), will (i) violate any constitution,
           statute, regulation, rule, injunction, judgment,
           order, decree, ruling, charge, or other restriction
           of any government, governmental agency, or court to
           which Cabletron and Acquisition is subject or any
           provision of their respective charters or bylaws or
           (ii) conflict with, result in a breach of, constitute
           a default under, result in the acceleration of,
           create in any party the right to accelerate,
           terminate, modify, or cancel, or require any notice
           under any agreement, contract, lease, license,
           instrument, or other arrangement to which Cabletron
           and Acquisition is a party or by which it is bound or
           to which any of its assets is subject.  None of
           Cabletron nor Acquisition  needs to give any notice
           to, make any filing with, or obtain any
           authorization, consent, or approval of any government
           or governmental agency in order for the Parties to
           consummate the transactions contemplated by this
           Agreement (including the assignments and assumptions
           referred to in  2 above), except for filings under
           the Hart-Scott-Rodino Act, which filings have been
           made.
           
                4.4. Brokers' Fees.  The Buyer has no Liability
           or obligation to pay any fees or commissions to any
           broker, finder, or agent with respect to the
           transactions contemplated by this Agreement for which
           any of the Sellers could become liable or obligated.
           
           5.   Covenants.  The Parties agree as follows:
           
                5.1. General.  Subject to the terms and
           conditions provided in this Agreement, each of the
           Parties will use its reasonable best efforts to take
           all action and to do all things necessary, proper, or
           advisable in order to consummate and make effective
           the transactions contemplated by this Agreement
           (including satisfaction, but not waiver, of the
           closing conditions set forth in  6 below).
           
                5.2. Notices and Consents. Each of the Sellers
           will give any notices to third parties, and will use
           its reasonable best efforts to obtain any third party
           consents, that are required to transfer the Acquired
           Assets to Buyer, and any other consent that the Buyer
           may reasonably request. Each of the Parties has
           filed any Notification and Report Forms and related
           material that it may be required to file with the
           Federal Trade Commission and the Antitrust Division
           of the United States Department of Justice under the
           Hart-Scott-Rodino Act, will use its reasonable best
           efforts to obtain an early termination of the
           applicable waiting period, and will make any further
           filings pursuant thereto that may be necessary in
           connection therewith, provided that neither party
           shall be obligated to divest any part of its business
           or assets or to agree to forego any business
           activities or opportunities, present or future, as a
           result of such reasonable best efforts obligation.
           
                5.3. Preservation of Business. Each of the
           Sellers will use its reasonable best efforts to keep
           the business and properties of the ENBU substantially
           intact, including its present operations, physical
           facilities, working conditions, and relationships
           with lessors, licensors, suppliers, customers, and
           employees.
           
                5.4. Full Access. Each of the Sellers will
           permit representatives of the Buyer to have full
           access at all reasonable times, and in a manner so as
           not to interfere with the normal business operations
           of the ENBU, to all premises, properties, personnel,
           books, records (including Tax records), contacts, and
           documents of or pertaining to the ENBU.
           
                5.5. Notice of Developments.  Each Party will
           give prompt written notice to the other Party of any
           material adverse development causing a breach of any
           of its own representations and warranties in  3 and
            4 above.  No disclosure by any Party pursuant to
           this  5.5, however, shall be deemed to amend or
           supplement the Disclosure Letter or to prevent or
           cure any misrepresentations, breach of warranty, or
           breach of covenant.
           
                5.6. Exclusivity. Each of the Sellers will not
           and will cause Seller's Subsidiaries, Affiliates,
           directors, officers, employees, representatives and
           agents not to directly or indirectly (i) solicit,
           initiate or encourage the submission of any proposal
           or offer or transaction from any Person relating to
           the sale or acquisition of the assets of the ENBU,
           the Assets of the ENBU or (ii) participate in any
           discussions or negotiations regarding, furnish any
           information with respect to, assist or participate
           in, or facilitate in any other manner any effort or
           attempt by any Person to do or seek any of the
           foregoing.  The Sellers will notify the Buyer
           immediately if any Person makes any bona fide written
           proposal, offer, inquiry, or contact with respect to
           any of the foregoing.
           
                5.7. Employee Matters.
           
                5.7.1.  Each of the Sellers agrees to (i)
           terminate all the employees who are engaged in the
           business relating to the Assets of the ENBU who
           Cabletron intends to hire after the Closing (the
           "Employees") immediately prior to Closing and to pay
           any and all Liabilities relating to such termination,
           including, without limitation any payments and
           benefits due such Employees pursuant to accrued
           salary and wages, pension, retirement, savings,
           health, welfare and other benefits and severance
           payments or similar payments of the Employees and
           (ii) provide to all Employees any notice (which
           notice shall be reasonably acceptable to Buyer)
           required under any law or regulations in respect of
           such termination including, without limitation COBRA.
           
                5.7.2.  As soon as practicable following Closing
           and in all events within twenty-one days thereafter,
           Sellers shall pay an amount equal to the grossed-up
           value (assuming an effective average tax rate of 37%
           for all participants) of the 1995 401(k) matching
           contribution on a fully vested basis to those
           Employees who participated in the Sellers' 401(k)
           savings plan during 1995, including applicable income
           taxes, FICA and similar amounts.  Buyer shall
           reimburse Sellers for the amount of such additional
           payment.  As soon as practicable following Closing
           and in all events within twenty-one days thereafter,
           Sellers shall pay to Employees an amount equal to the
           grossed-up value (assuming an effective average tax
           rate of 37% for all participants) of the unvested
           amount in the accounts of all Employees under
           Sellers' Plan, taking into account all contributions
           for 1995.  Promptly thereafter Sellers shall cause
           the accounts of all Employees under Sellers' Plan,
           taking into account all contributions for 1995, to be
           distributed or transferred in a direct rollover.  In
           connection with such distribution or direct rollover,
           the plan administrator of Sellers' Plan shall certify
           to each distributee, including any plan or IRA
           accepting a rollover or direct rollover, that after
           taking into account such distribution or direct
           rollover Sellers' Plan is and remains qualified under
           Section 401(a) et seq. of the Code.
           
                5.7.3.  Employees (other than any Employee who
           is not employed by Buyer or who is in an ineligible
           classification of employees) shall be eligible to
           participate in Buyer's 401(k) plan following Closing
           without regard to the normal entry-date requirements
           under such plan.
           
                5.7.4.  Any Employee who immediately after the
           Closing becomes an active full-time employee of Buyer
           shall be eligible to participate in Buyer's employee
           health, life insurance and disability plans as of the
           date such employee commences active employment with
           the Buyer; provided, however, any and all other
           terms, conditions and exclusions of such plans
           (including, but not limited to, pre-existing
           condition exclusions, actively-at-work requirements,
           evidence of insurability requirements, and
           nonconfinement/nondisability requirements) shall
           fully apply.
           
                5.7.5. Contemporaneously with the Closing,
           Sellers agree to vest any unvested options held by
           any Employees and to extend the period during which
           such options may be exercised to one year following
           Closing.
           
                5.7.6. After Closing, SMC will promptly pay
           Employees' accrued vacation through Closing.
           
                5.8. Retention of and Access to Records after
           Closing. The Sellers may retain a single set of
           copies of any books and records of the ENBU which
           Sellers reasonably believe will be required by them
           for the purpose of: (i) performing any of Sellers'
           accounting, public reporting, or other administrative
           functions which are performed in the ordinary course
           of Sellers' business, or (ii) complying with
           discovery requests arising in all litigation
           currently pending against Sellers or otherwise
           conducting SMC's defense in such actions. Sellers
           shall destroy such copies upon the Sellers'
           determination that any such copies are no longer
           reasonably required by them for either of the
           purposes set forth in the preceding sentence.
           Seller's use, disclosure and disposition of such
           copies shall otherwise be governed in accordance with
           Section 7.1 to the extent that such copies contain
           Exclusive Confidential Information.  For a period of
           five years after the Closing Date, the Sellers and
           their representatives shall have reasonable access to
           any other books and records of the ENBU to the extent
           that such access may reasonably be required by any of
           the Sellers in connection with matters relating to or
           affected by the operations of the ENBU prior to the
           Closing Date.  Such access shall be afforded by Buyer
           upon receipt of reasonable advance notice and during
           normal business hours. Each of the Sellers shall be
           solely responsible for any costs or expenses incurred
           by it pursuant to this  5.8.  If Buyer shall desire
           to dispose of any of such books and records prior to
           the expiration of such five-year period, Buyer shall,
           prior to such disposition, give the Sellers a
           reasonable opportunity, at Sellers' expense, to
           segregate and remove such books and records as any of
           the Sellers may select.
           
                5.9. Bulk Sales Compliance; Liens under Chapter
           62C, Section 51 of the Massachusetts General Laws
           Liens under Chapter 62C, Section 51 of the
           Massachusetts General Laws;.  Buyer hereby waives
           compliance by the Sellers with the provisions of any
           bulk transfer law which may be applicable to the
           transactions contemplated by this Agreement.
           Further, the Parties recognize that the Massachusetts
           Commissioner of Revenue may not, by Closing, have
           granted a waiver of any Tax Lien that might accrue
           pursuant to Chapter 62C, 51 of the Massachusetts
           General Laws.  Buyer hereby consents to such Lien
           arising upon the sale of the Acquired Assets;
           provided, however, that such consent is conditioned
           upon Sellers indemnifying and holding harmless Buyer
           against and in respect of any Loss (as defined in
           9.2 below) resulting from the existence of any Tax
           Lien on the Acquired Assets under said 51.
           
                5.10.     Transfer Taxes. Buyer and Sellers each
           agree to bear fifty percent of any Massachusetts
           sales and use Taxes on the transfer of the Acquired
           Assets hereunder, including any such Taxes which may
           be imposed in the event Sellers do not obtain a
           clearance certificate from the Massachusetts
           Commissioner of Revenue.  Sellers have applied for a
           clearance certificate and shall use their best
           efforts to obtain such certificate.
           
                5.11.     Product Warranty Repair and Service.
           Buyer agrees that for a period of 18 months following
           Closing, Buyer shall perform the warranty work for
           products sold by Sellers prior to the Closing date
           pursuant to Buyer's normal repair or replacement
           procedures.  To the extent that Buyer's actual costs
           for providing such warranty work does not exceed the
           warranty reserve on the Most Recent Balance Sheet,
           Buyer shall bear all costs of such warranty without
           reimbursement from Sellers.  However, Buyer shall be
           entitled to indemnification by Sellers pursuant to
           the procedures set forth in Section 9.2 below to the
           extent that Buyer's cost of providing such warranty
           work for products for which Sellers' standard
           warranty had not yet expired exceeds the amount of
           such warranty reserves.  In the event that Buyer
           shall determine to provide additional warranty work
           beyond the applicable warranty provided by Seller,
           the cost of providing such optional warranty work
           shall be borne by Buyer, and Buyer shall not be
           entitled to indemnification or credit in connection
           with such optional warranty work.  In addition, Buyer
           shall not be entitled to credit or indemnification
           for the incremental cost of providing new replacement
           products instead of repaired products, where a
           repaired product would be adequate to satisfy
           Sellers' warranty obligation.
           
                In addition, SMC shall indemnify Buyer pursuant
           to the procedures set forth in  9.2 below for
           liability incurred by Buyer due to Epidemic Failure.
           Such liability shall be deemed to be Buyer's direct
           costs due to repair, replacement and product recalls
           in the event of an Epidemic Failure.  An Epidemic
           Failure shall be deemed to be a repetitive failure of
           a product originating from a single cause which has
           such severity and frequency of occurrence that the
           exercise of reasonable product business practice
           would require a product recall, repair or
           replacement.  Liability for product warranty and
           repair and servicing shall be allocated among the
           Parties as provided in  2.3, 2.4 and 9.
           
                5.12.     Delivery of Audited Financial
           Statements.  On or before January 19, 1996, SMC shall
           deliver to Buyer an audited balance sheet (statement
           of assets and liabilities) and a statement of
           revenues and expenses for the fiscal year ended
           February 28, 1995 for the Acquired Assets acquired by
           Buyer, subject to the Assumed Liabilities (the
           "Audited Financial Statements").  The Audited
           Financial Statements shall be prepared in accordance
           with GAAP applied on a consistent basis throughout
           the periods covered thereby and shall be consistent
           with the books and records of the ENBU.  Sellers
           shall deliver, together with the Audited Financial
           Statements, an opinion of Sellers' independent
           auditors, Arthur Andersen & Co., that the Audited
           Financial Statements present fairly the financial
           condition and results of operations of the business
           relating to the Assets of the ENBU.  Sellers shall
           make available to Buyer and Buyer's auditors Sellers'
           work papers and backup materials used in the
           preparation of the Audited Financial Statements.
           
                5.13.     License of Trademarks.  In order to

           Agreement, (i) after the Closing, Sellers agree to
           and hereby do license on a nonexclusive, royalty-free
           basis for the limited purpose of the sale and resale
           of the Inventory the trademarks EliteView  and
           TigerSwitch  and (ii) after the Closing, Buyer agrees
           to and hereby does license on a nonexclusive, royalty-
           free basis, for the limited purpose of using existing
           sales collateral and packaging and similar items
           retained by Seller, the ENBU trademarks purchased by
           Buyer pursuant to this Agreement.
           
                5.14.     Cooperation in Connection with Pending
           Litigation.  Buyer agrees to cooperate in Sellers'
           defense of any litigation pending against Sellers on
           the date of Closing as required by law or as
           otherwise reasonably necessary, including making
           Employees reasonably available to the extent doing so
           would not unduly interfere with Buyer's business.
           Sellers agree to pay all reasonable out-of-pocket
           costs incurred by Buyer in connection with such
           cooperation. The foregoing shall not apply to Penril
           Datacomm, Inc.  v.  Standard Microsystems
           Corporation, et.  al., Case No.  106878, which is the
           subject of a separate letter between the Parties.
           
                5.15.     General Skill and Knowledge. Each of
           the Parties agree that employees of Sellers who are
           either retained by Sellers or terminated by Sellers
           and hired by Buyer may use the general skill and
           knowledge they have developed in the future business
           of Sellers or Buyer, as the case may be.
           
                5.16.      Relationship with Nu-Link. SMC and
           Buyer agree that neither of them shall enter into any
           agreement with Nu-Link, Inc. that prohibits Nu-Link,
           Inc. from entering into an agreement with the other.
           
                5.17.     License under Multimedia Patent.  In
           order to effect the transactions contemplated by this
           Agreement, after the Closing, Buyer agrees to and
           hereby does grant to Sellers the rights with respect
           to the Multimedia Patent set forth in Section 2.2(d).
           
                5.18.     Trillium Software.  Sellers agree to
           use their reasonable best efforts to cause Trillium
           to grant to Buyer a license for the Trillium software
           being transferred to the Buyer satisfactory to Buyer
           granting the Buyer rights equivalent to the rights
           held by the Sellers in such software.

                6.1. Conditions to Obligation of the Buyer.  The

           consummation of any of the transactions contemplated

           7.   Confidentiality.
           
                7.1. Confidential Information Related
           Exclusively to the Business Relating to the Assets of
           the ENBU.  Each of the Sellers will treat and hold as
           confidential all of the Confidential Information
           related exclusively to the Acquired Assets (other
           than the Acquired Assets identified in Sections
           2.1(f)(ii) and 2.1(h)(ii)) and all other Confidential
           Information related exclusively to the business
           relating to the Assets of the ENBU (the "Exclusive
           Confidential Information"), refrain from using any of
           the Exclusive Confidential Information except in
           connection with this Agreement, and will use
           reasonable best efforts to deliver promptly to the
           Buyer or destroy, at the request and option of the
           Buyer, all tangible embodiments (and, except as set
           forth in Section 5.8, all copies) of the Exclusive
           Confidential Information which are in his or its
           possession. In the event that any of the Sellers is
           requested or required (by oral question or request
           for information or documents in any legal proceeding,
           interrogatory, subpoena, civil investigative demand,
           or similar process) to disclose any Exclusive
           Confidential Information, such Seller will notify the
           Buyer promptly of the request or requirement so that
           the Buyer may seek an appropriate protective order or
           waive compliance with the provisions of this  7.1.
           If, in the absence of a protective order or the
           receipt of a waiver hereunder, any of the Sellers is,
           on the advice of counsel, compelled by any government
           agency or court to disclose any Exclusive
           Confidential Information, then such Seller may
           disclose the Exclusive Confidential Information;
           provided, however, that the disclosing Seller shall
           use his or its best efforts to obtain, at the request
           of the Buyer, an order or other assurance that
           confidential treatment will be accorded to such
           portion of the Exclusive Confidential Information
           required to be disclosed as the Buyer shall
           designate.
           
                7.2. Shared Confidential Information.  Each of
           the Parties will treat and hold as confidential all
           of the Confidential Information other than the
           Exclusive Confidential Information (the "Shared
           Confidential Information") and will use such Shared
           Confidential Information only for purposes consistent
           with this Agreement.  In the event that any of the
           Parties is requested or required (by oral question or
           request for information or documents in any legal
           proceeding, interrogatory, subpoena, civil
           investigative demand, or similar process) to disclose
           any Shared Confidential Information, such Party will
           notify the other Parties promptly of the request or
           requirement so that the such other Parties may seek
           an appropriate protective order or waive compliance
           with the provisions of this  7.2.  If, in the
           absence of a protective order or the receipt of a
           waiver hereunder, any of the Parties is, on the
           advice of counsel, compelled by any government agency
           or court to disclose any Shared Confidential
           Information, then such Party may disclose such Shared
           Confidential Information; provided, however, that the
           disclosing Party shall use his or its best efforts to
           obtain, at the request of another Party, an order or
           other assurance that confidential treatment will be
           accorded to such portion of the Shared Confidential
           Information required to be disclosed as the other
           Party shall designate.
           
           8.   Noncompetition.
           
                8.1. Noncompetition.  The Sellers agree, for
           themselves and their subsidiaries and any entity
           which they control, that, in consideration of the
           purchase by the Buyer hereunder, they shall not, on
           or prior to the date which is three (3) years after
           the Closing Date (the "Restricted Period"), directly
           or indirectly, run, own, manage, operate, control,
           invest (other than for minority investments) or
           participate in any business, venture or activity
           which engages in the business of backbone enterprise
           level switching solutions, including ES/1 class
           switches, in direct sale to end users and in Fortune
           1000 class organizations markets; provided, however,
           that the Sellers continue to have the right during
           the Restricted Period and thereafter, to engage in
           the Sellers' current LAN businesses (other than
           backbone enterprise level switching solutions,
           including ES/1 class switches) and in workgroup
           switching and fast Ethernet switching, in the sale of
           either:  (i)  products for the low- to mid-range LAN
           markets or (ii) products which are appropriate for
           two-step distribution. Any products that Sellers are
           permitted to sell pursuant to the foregoing provision
           may be sold by Sellers in any market, through any
           channel or directly to customers, and to any customer
           desired by Sellers. The foregoing provision shall not
           bind or otherwise apply to any Person which merges or
           consolidates with SMC with the result that SMC is not
           the surviving entity or purchases all or
           substantially all of the assets of SMC, the Desktop
           Networks Business Unit or the business related to the
           Retained Products set forth on Schedule 1.1 and upon
           such transaction, the covenant set forth in this 8.1
           shall terminate as to such transferred businesses.
           
                8.2. Each of the Parties agree that for a period
           of two (2) years from and after the Closing Date it
           will not, without the consent of the other Party,
           directly or indirectly solicit or initiate contact
           with any of the employees of the other Party with a
           view of inducing or encouraging such employees to
           leave the employ of the other Party for the purpose
           of being hired by the soliciting Party or an employer
           affiliated with it.  Mass media advertising of open
           positions, job fairs and other recruiting programs
           not directed at specific individuals shall not in and
           of themselves be deemed solicitation or initiation of
           contact for purposes of this paragraph.
           
           9.   Indemnification.
           
                9.1. Survival of Representations and Warranties.
           All of the representations and warranties of the
           Sellers (except for those contained in  3.6 and
           3.14) contained herein or in any document
           certificate or other instrument required to be
           delivered hereunder shall survive the Closing and
           continue in full force and effect until 18 months
           after Closing, after which such representations and
           warranties shall terminate.  All of the
           representations and warranties of the Buyer contained
           in  4 shall survive the Closing and shall continue
           in full force and effect until 18 months after
           Closing.  The representations and warranties of the
           Sellers contained in  3.6 and 3.14 shall survive the
           Closing and shall continue in full force and effect
           without limit as to time (subject to any applicable
           statutes of limitations).
           
                9.2. Indemnity by Sellers.  SMC hereby agrees to
           indemnify, defend and hold harmless Buyer and its
           directors, officers and Affiliates against and in
           respect of all Liabilities, obligations, judgments,
           Liens, injunctions, charges, orders, decrees,
           rulings, damages, dues, assessments, Taxes, losses,
           fines, penalties, expenses, fees, costs, amounts paid
           in settlement (including reasonable attorneys' and
           expert witness fees and disbursements in connection
           with investigating, defending or settling any action
           or threatened action), in each case net of (i) income
           tax benefits to the Buyer to the extent realized by
           the Buyer in the Tax year in which the Loss occurred
           and (ii) insurance proceeds if and when actually
           received by the Buyer, provided, however, that Buyer
           shall retain the right in its sole discretion to
           determine whether to pursue such claims by, through
           or against an insurer or to bring such claims
           directly or indirectly against the Sellers pursuant
           to this  9.2, arising out of any claim, damages,
           complaint, demand, cause of action, audit,
           investigation, hearing, action, suit or other
           proceeding asserted or initiated or otherwise
           existing in respect of any  matter  (collectively,
           the "Losses") that results from:
           
                (a)  the inaccuracy of any representation or
           warranty made by Sellers herein which Buyer has not
           received express written notice of prior to Closing,
           or resulting from any misrepresentation, breach of
           warranty as if all materiality provisions were not
           contained therein or nonfulfillment of any agreement
           or covenant of Sellers contained herein (including
           the Disclosure Letter and Exhibits hereto, excluding
           the Product Agreement) or in any agreement or
           instrument required to be entered into in connection
           herewith or from any misrepresentation in or omission
           from any schedule, document, certificate or other
           instrument required to be furnished by Sellers
           hereunder; provided, however, that SMC shall be
           liable under this  9.2(a) in respect of Losses only
           to the extent that the aggregate of such Losses
           exceeds $500,000 in which case the Sellers will be
           liable for the amount of such Losses in excess of
           $500,000 up to an aggregate amount equal to
           $7,700,000;
           
                (b)  any Liability of the Sellers or the ENBU
           which is not an Assumed Liability (including any
           Liability which is not an assumed Liability of the
           Sellers or the ENBU that becomes a Liability of the
           Buyer under any bulk transfer law of any
           jurisdiction, under any common law doctrine of de
           facto merger or successor liability, or otherwise by
           operation of law); and
           
                (c)  any Liability in respect of any Taxes
           relating to the Assets of the ENBU attributable to
           periods beginning before and ending on the Closing
           Date.
           
           In the event that SMC may be obliged to indemnify
           Buyer under both subsection (a) and subsection (b) or
           subsection (c) of this  9.2, its obligations under
           subsection (b) or subsection (c), as the case may be,
           shall be controlling and the limitations provided in
            9.1 and 9.2(a) hereof  relating to its obligations
           in respect of Losses resulting from the inaccuracy of
           any representation and warranty, or any
           misrepresentation, breach of warranty or non-
           fulfillment of an agreement or covenant as described
           in  9.2(a), shall not apply.  Buyer shall provide
           Sellers written notice for any claim made in respect
           of the indemnification provided in this  9.2,
           whether or not arising out of a claim by a third
           party.
           
                9.3. Environmental Indemnification.
           Notwithstanding any other provision of this Agreement
           to the contrary, this  9.3 shall control and limit
           Sellers  obligation to indemnify Buyer for
           Environmental Liabilities and Costs and Safety
           Liabilities and Costs.  Sellers agree to indemnify
           and hold harmless Buyer against any Losses relating
           to Environmental Liabilities and Costs and Safety
           Liabilities and Costs to the extent arising out of
           any condition existing at or prior to Closing which
           constitutes a violation of or gives rise to a duty to
           remediate under Environmental Laws or Safety Laws
           which occurred on property which is owned or leased
           by Sellers or on property which is not owned or
           leased by Sellers relating to the business relating
           to the Assets of the ENBU, without limit in point of
           time, knowledge or amount.
           
                9.4. Indemnity by Buyer.  Buyer hereby agrees to
           indemnify, defend and hold harmless Sellers and their
           respective directors, officers and Affiliates against
           and in respect of all Liabilities, obligations,
           judgments, liens, injunctions, charges, orders,
           decrees, rulings, damages, dues, assessments, Taxes,
           losses, fines, penalties, damages, expenses, fees,
           costs, amounts paid in settlement (including
           reasonable attorneys' and expert witness fees and
           disbursements in connection with investigating,
           defending or settling any action or threatened
           action) arising out of any claim, complaint, demand,
           cause of action, audit, investigation, hearing,
           action, suit or other proceeding asserted or
           initiated in respect of any matter that results from
           the inaccuracy of any representation or warranty made
           by Buyer herein, or resulting from any
           misrepresentation, breach of warranty or
           nonfulfillment of any agreement or covenant of Buyer,
           including Buyer's agreement to assume certain
           Liabilities of the ENBU pursuant to  2.2 of this
           Agreement, contained herein or in any agreement or
           instrument required to be entered into in connection
           herewith or from any misrepresentation in or omission
           from any schedule, document, certificate or other
           instrument required to be furnished by Buyer
           hereunder.
           
                9.5. Matters Involving Third Parties.
           
                (a)  If any third party shall notify any Party
           (the "Indemnified Party") with respect to any matter
           (a "Third Party Claim") which may give rise to a
           claim for indemnification against any other Party
           (the "Indemnifying Party") under this  9, then the
           Indemnified Party shall promptly notify each
           Indemnifying Party thereof in writing; provided,
           however, that no delay on the part of the Indemnified
           Party in notifying any Indemnifying Party shall
           relieve the Indemnifying Party from any obligation
           hereunder unless (and then solely to the extent) the
           Indemnifying Party thereby is prejudiced.
           
                (b)  Any Indemnifying Party will have the right
           to defend the Indemnified Party against the Third
           Party Claim with counsel of its choice reasonably
           satisfactory to the Indemnified Party so long as (A)
           the Indemnifying Party notifies the Indemnified Party
           in writing within 15 days after the Indemnified Party
           has given notice of the Third Party Claim that the
           Indemnifying Party will indemnify the Indemnified
           Party from and against the entirety of any Losses the
           Indemnified Party may suffer resulting from, arising
           out of, relating to, in the nature of, or caused by
           the Third Party Claim, (B) the Indemnifying Party
           provides the Indemnified Party with evidence
           reasonably acceptable to the Indemnified Party that
           the Indemnifying Party will have the financial
           resources to defend against the Third Party Claim and
           fulfill its indemnification obligations hereunder,
           (C) the Third Party Claim involves only money damages
           and does not seek an injunction or other equitable
           relief, and (D) settlement of, or an adverse judgment
           with respect to, the Third Party Claim is not, in the
           good faith judgment of the Indemnified Party, likely
           to result in a material restriction upon the business
           practices of the Indemnified Party in respect of the
           Assets of the ENBU, and (E) the Indemnifying Party
           conducts the defense of the Third Party Claim
           actively and diligently.
           
                (c)  So long as the Indemnifying Party is
           conducting the defense of the Third Party Claim in
           accordance with  9.2(b) above, (A) the Indemnified
           Party may retain separate co-counsel at its sole cost
           and expense and participate in the defense of the
           Third Party Claim, (B) the Indemnified Party will not
           consent to the entry of any judgment or enter into
           any settlement with respect to the Third Party Claim
           without the prior written consent of the Indemnifying
           Party (which consent shall not unreasonably be
           withheld), and (C) the Indemnifying Party will not
           consent to the entry of any judgment or enter into
           any settlement with respect to the Third Party Claim
           unless written agreement is obtained releasing the
           Indemnified Party from all liability thereunder.  The
           Indemnified Party shall cooperate in all reasonable
           respects with the Indemnifying Party and such
           attorneys in the investigation, trial and defense of
           such lawsuit or action and any appeal arising
           therefrom.
           
                (d)  In the event any of the conditions in
            9.2(b) above is or becomes unsatisfied, however,
           (A) the Indemnified Party may defend against, and
           consent to the entry of any judgment or enter into
           any settlement with respect to, the Third Party Claim
           in any manner it may deem appropriate (and the
           Indemnified Party need not consult with, or obtain
           any consent from, any Indemnifying Party in
           connection therewith), (B) the Indemnifying Parties
           will reimburse the Indemnified Party promptly and
           periodically for the costs of defending against the
           Third Party Claim (including attorneys' fees and
           expenses), and (C) the Indemnifying Parties will
           remain responsible for any Losses the Indemnified
           Party may suffer resulting from, arising out of,
           relating to, in the nature of, or caused by the Third
           Party Claim to the fullest extent provided in this
            9.
           
                9.6. Other Indemnification Provisions.  Each of
           the Sellers hereby agrees that it will not make any
           claim for indemnification against any of the Buyer
           and its Subsidiaries solely by reason of the fact
           that he or it was a director, officer, employee, or
           agent of the Sellers, the ENBU or was serving at the
           request of any such entity as a partner, trustee,
           director, officer, employee, or agent of another
           entity (whether such claim is for judgments, damages,
           penalties, fines, costs, amounts paid in settlement,
           losses, expenses, or otherwise and whether such claim
           is pursuant to any statute, charter document, bylaw,
           agreement, or otherwise) with respect to any action,
           suit, proceeding, complaint, claim, or demand brought
           by the Buyer against such Sellers (whether such
           action, suit, proceeding, complaint, claim, or demand
           is pursuant to this Agreement, applicable law, or
           otherwise) unless the underlying claim is an Assumed
           Liability.
           
           10.  Termination.
           
                10.1.     Termination of Agreement.  Certain of
           the Parties may terminate this Agreement as provided
           below.
           
                (a)  the Parties may terminate this Agreement by
           mutual written consent at any time prior to the
           Closing;
           
                (b)  the Buyer may terminate this Agreement by
           giving written notice to SMC at any time prior to the
           Closing (A) in the event any of the Sellers has
           breached any representation, warranty, or covenant
           contained in this Agreement in any material respect,
           the Buyer has notified such Seller of the breach, and
           the breach has continued without cure for a period of
           30 days after the notice of breach or (B) if the
           Closing shall not have occurred on or before the
           earliest to occur of 45 days after the expiration or
           other termination of all applicable waiting periods
           under the Hart-Scott-Rodino-Act and February 29,
           1996, by reason of the failure of any condition
           precedent under  6.1 hereof (unless the failure
           results primarily from the Buyer itself breaching any
           representation, warranty, or covenant contained in
           this Agreement); and
           
                (c) SMC may terminate this Agreement by giving
           written notice to the Buyer at any time prior to the
           Closing (A) in the event the Buyer has breached any
           representation, warranty, or covenant contained in
           this Agreement in any material respect, SMC has
           notified the Buyer of the breach, and the breach has
           continued without cure for a period of 30 days after
           the notice of breach or (B) if the Closing shall  not
           have occurred on or before the earliest to occur of
           45 days after the expiration or other termination of
           all applicable waiting periods under the Hart-Scott-
           Rodino-Act and February 29, 1996, by reason of the
           failure of any condition precedent under  6.2 hereof
           (unless the failure results primarily from the
           Company itself breaching any representation,
           warranty, or covenant contained in this Agreement).
           
                10.2.     Effect of Termination.  If any Party
           terminates this Agreement pursuant to  10.1 above,
           all rights and obligations of the Parties hereunder
           shall terminate without any Liability of any Party to
           any other Party (except for any Liability of any
           Party then in breach).
           
           11.  Miscellaneous.
           
                11.1.     Press Releases and Public
           Announcements.  No Party shall issue any press
           release or make any public announcement relating to
           the subject matter of this Agreement prior to the
           Closing without the prior written approval of the
           other Party; provided, however, that any Party may
           make any public disclosure it believes in good faith
           is required by applicable law or any listing or
           trading agreement concerning its publicly-traded
           securities (in which case the disclosing Party will
           advise the other Party prior to making the
           disclosure).
           
                11.2.     No Third Party Beneficiaries.  This
           Agreement shall not confer any rights or remedies
           upon any Person other than the Parties and their
           respective successors and permitted assigns.
           
                11.3.     Entire Agreement.  This Agreement
           (including the documents referred to herein and
           attached hereto) constitutes the entire agreement
           between the Parties and supersedes any prior
           understandings, agreements, or representations by or
           between the Parties, written or oral, to the extent
           they related in any way to the subject matter hereof,
           including but not limited to the Confidentiality
           Agreement between Cabletron and SMC dated October 20,
           1995.
           
                11.4.     Succession and Assignment.  This
           Agreement shall be binding upon and inure to the
           benefit of the Parties named herein and their
           respective successors and permitted assigns. No Party
           may assign either this Agreement or any of its
           rights, interests, or obligations hereunder without
           the prior written approval of the other Party;
           provided, however, that the Buyer may (i) assign any
           or all of its rights and interests hereunder to one
           or more of its Affiliates and (ii) designate one or
           more of its Affiliates to perform its obligations
           hereunder and that the Sellers may assign any or all
           of their rights and interests, but not its
           obligations, hereunder to a wholly-owned subsidiary
           of SMC.
           
                11.5.     Counterparts.  This Agreement may be
           executed in one or more counterparts, each of which
           shall be deemed an original but all of which together
           will constitute one and the same instrument.
           
                11.6.     Headings.  The section headings

           set forth.
           
                11.8.     Governing Law.  This Agreement shall
           be governed by and construed in accordance with the
           domestic laws of the State of Delaware without giving
           effect to any choice or conflict of law provision or
           rule (whether of the State of Delaware or any other
           jurisdiction) that would cause the application of the
           laws of any jurisdiction other than the State of
           Delaware.
           
                11.9. Amendments and Waivers.  No amendment of
           any provision of this Agreement shall be valid unless
           the same shall be in writing and signed by the Buyer
           and the Sellers.  No waiver by any Party of any
           default, misrepresentation, or breach of warranty or
           covenant hereunder, whether intentional or not, shall
           be deemed to extend to any prior or subsequent
           default, misrepresentation, or breach of warranty or
           covenant hereunder or affect in any way any rights
           arising by virtue of any prior or subsequent such
           occurrence.
           
                11.10. Severability.  Any term or provision of
           this Agreement that is invalid or unenforceable in
           any situation in any jurisdiction shall not affect
           the validity or enforceability of the remaining terms
           and provisions hereof or the validity or
           enforceability of the offending term or provision in
           any other situation or in any other jurisdiction.
           
                11.11.  Expenses.  Each of the Buyer and the
           Sellers will bear his or its own costs and expenses
           (including legal fees and expenses) and the Sellers
           will bear all of the costs and expenses (including
           legal fees and expenses) of the ENBU incurred in
           connection with this Agreement and the transactions
           contemplated hereby. Sellers will bear all fees of
           Robertson Stephens & Company, L. P., and any
           associated costs and expenses.
           
                11.12.  Construction.  The Parties have
           participated jointly in the negotiation and drafting
           of this Agreement. In the event an ambiguity or
           question of intent or interpretation arises, this
           Agreement shall be construed as if drafted jointly by
           the Parties and no presumption or burden of proof
           shall arise favoring or disfavoring any Party by
           virtue of the authorship of any of the provisions of
           this Agreement. Any reference to any federal, state,
           local, or foreign statute or law shall be deemed also
           to refer to all rules and regulations promulgated
           thereunder, unless the context requires otherwise.
           The word "including" shall mean including without
           limitation.  For purposes of the Disclosure Letter,
           each disclosure: (i) applies only to the particular
           section referenced unless a disclosure is
           specifically cross-referenced in a separate section
           or otherwise clearly and unambiguously applies to
           another section; and (ii) shall be deemed to
           adequately disclose an exception to a representation
           or warranty only where such disclosure expressly
           identifies the exception.  Without limiting the
           generality of the foregoing, the mere identification
           (or inclusion of a copy) of a document or other item
           shall not be deemed adequate to disclose an exception
           to a representation or warranty made herein (unless
           the representation or warranty has to do with the
           existence of the document or other item itself)
           unless a review of such item would provide a
           reasonable disclosure of such exception. The Parties
           intend that each representation, warranty, and
           covenant contained herein shall have independent
           significance. If any Party has breached any
           representation, warranty, or covenant contained
           herein in any respect, the fact that there exists
           another representation, warranty, or covenant
           relating to the same subject matter (regardless of
           the relative levels of specificity) which the Party
           has not breached shall not detract from or mitigate
           the fact that the Party is in breach of the first
           representation, warranty, or covenant.
           
                11.13.  Incorporation of Exhibits and Schedules.
           The Exhibits and Schedules identified in this
           Agreement are incorporated herein by reference and
           made a part hereof.
           
                11.14.  Specific Performance.  Each of the
           Parties acknowledges and agrees that the other Party
           would be damaged irreparably in the event any of the
           provisions of this Agreement are not performed in
           accordance with their specific terms or otherwise are
           breached. Accordingly, each of the Parties agrees
           that the other Party shall be entitled to an
           injunction or injunctions to prevent breaches of the
           provisions of this Agreement and to enforce
           specifically this Agreement and the terms and
           provisions hereof in any action instituted in any
           court of the United States or any state thereof
           having jurisdiction over the Parties and the matter
           in addition to any other remedy to which it may be
           entitled, at law or in equity.
           
                11.15.  Resolution of Disputes.
           
                11.15.1.  If a dispute arises between the
           parties relating to this Agreement, it shall be
           resolved solely in accordance with the following
           procedures. Either Party may call a meeting by
           written notice to be attended by individuals with
           decision-making authority regarding the dispute.
           Within ten days of the initial request, the Parties
           will meet and attempt to resolve the dispute. If the
           Parties are unable to resolve the dispute at such
           meeting, either Party may, within five days of such
           meeting, call a meeting by written notice to be
           attended by the Chief Executive Officer of SMC and
           the Chief Operating Officer of Cabletron. Within ten
           days of the initial request, the Chief Executive
           Officer of SMC and the Chief Operating Officer of
           Cabletron will meet and attempt to resolve the
           dispute.
           
                11.15.2.  If the Chief Executive Officer of SMC
           and the Chief Operating Officer of Cabletron are
           unable to resolve the dispute at their meeting,
           either Party may, within five days of such meeting,
           submit the dispute to expedited mediation under the
           Commercial Mediation Rules of the American
           Arbitration Association ("AAA").  The mediator shall
           not have authority to impose a settlement upon the
           parties to the dispute, but will attempt to assist
           them in reaching a satisfactory resolution of the
           dispute.  The mediator shall end such mediation
           whenever, in his or her judgment, further efforts at
           mediation would not contribute to resolution of the
           dispute.  If the dispute is not resolved through
           mediation in ten days from submission of the dispute
           to the mediator, either Party may terminate
           mediation.
           
                11.15.3.  Upon termination of mediation, the
           Parties may avail themselves of any remedies that are
           available under this Agreement and applicable law,
           including litigation.
           
                11.15.4.  In addition to the procedures set
           forth in subsections 11.15.1 through 11.15.3, in the
           event of a dispute arising from conduct by one Party
           that is likely to cause irreparable harm to another
           Party, such other Party may, at its option, bring an
           action in state or federal court solely for the
           purpose of obtaining an injunction maintaining the
           status quo ante during the pendency of the other
           procedures specified in subsections 11.15.1 through
           11.15.3.
           
           IN WITNESS WHEREOF, the Parties hereto have executed
           this Agreement on the date first above written.

CABLETRON FINALIZES AGREEMENT TO ACQUIRE SMC SWITCHING GROUP

ROCHESTER, NH -- January 15, 1996  -- Cabletron Systems (NYSE:CS)
announced today it has completed its acquisition of the
Enterprise Networks Switching Group of Standard Microsystems
Corporation (SMC), a leading supplier of high performance LAN
(Local Area Network) technologies.

Cabletron is acquiring the assets and technology of SMC's
Enterprise Networks Switching Group located in Andover, MA, for
$75.9 million in cash and the assumption of certain specified
liabilities.

The acquisition augments Cabletron's extensive high-end
SmartSwitch family allowing the company to deliver a
comprehensive line of Fast Ethernet products for enterprise-wide
switching applications.

The acquisition significantly expands Cabletron's presence in the
Fast Ethernet market, providing scaleable Fast Ethernet switching
solutions for small, medium and large networks.

"We are very pleased with the smooth integration of the former
SMC Enterprise Switching Group into Cabletron," said S. Robert
Levine, Cabletron's president and chief executive officer.
"Combining Cabletron's leading-edge LAN switching and management
technologies with SMC's Fast Ethernet products gives our
customers the widest range of switching solutions available
today," Levine said.

Cabletron Systems is the largest company in the world dedicated
exclusively to computer networking products and services.  With
corporate headquarters in Rochester, NH, the company has 90
offices around the world and employs 5,500 people. Based on its
Synthesis product framework Cabletron develops, manufactures,
markets and services both shared and internetworking products, as
well as the industry's most advanced network and systems
management software.

Cabletron directly services customer sites around the globe and
provides 7 X 24 support coverage, including free telephone
support during normal business hours.  A component of the S&P 500
index, Cabletron's common stock is traded over the New York Stock
Exchange under the symbol CS.  Over the last four quarters the
company has reported record revenue of approximately $1 billion
and earnings of $202 million.





01/15 Standard Microsystems Completes Sale Of Enterprise Networks
Business Unit To Cabletron Systems

HAUPPAUGE, N.Y.--(BUSINESS WIRE)--Jan. 15, 1996--Standard
Microsystems Corp. (SMC(R)) (NASDAQ:SMSC) announced today that it
has completed the sale of its Enterprise Networks Business Unit
(ENBU) to Cabletron Systems, Inc. for approximately $75 million
in cash.

During SMC's third quarter, ended Nov. 30, 1995, the ENBU
represented about 5% of the company's total revenues and approximately
9% of the revenues of its System Products Division.

The restructured System Products Division now consists of the
Desktop Networks Business Unit (DNBU) and the Workgroup Networks Business
Unit (WNBU).  The DNBU will continue to develop and market
advanced network interface cards.  The WNBU will concentrate on
the development and marketing of workgroup hubs and new workgroup
switches.  The sale of the ENBU will also enable the company's
System Products Division to focus its sales and marketing efforts
on its value-added resellers and channel partners where, for
several years, it has been a leading worldwide supplier.

As previously announced, SMC Plans to use certain proceeds from
this sale to increase the levels of production from its Component
Products Division's semiconductor wafer foundry suppliers and to
expand the product line and strengthen the sales and marketing
channels of the System Products Division.

Standard Microsystems Corp., with headquarters in Hauppauge, is a
leading worldwide supplier of personal computer (PC) local area
network (LAN) system products and semiconductor very-large-scale
integrated (VLSI) circuits.  SMC's Component Products Division
supplies VLSI circuits for PC and embedded control systems.
These include input/output (I/O) devices for disk drive control,
communications interface and other PC motherboard functions,
Ethernet and Fast Ethernet controllers for LAN applications and
ARCNET controllers for embedded networking.

SMC's System Products Division provides a broad range of
networking solutions for scaling, managing and connecting LANs.  Its
products include network interface cards, hubs, and LAN switches
for interconnecting LANs.  SMC has an installed base of over 10
million nodes.  SMC uses internally developed integrated circuits
to achieve lower costs and to enhance product performance.
