                               BAY NETWORKS, INC.
                     EXECUTIVE RETENTION AND SEVERANCE PLAN

                            ADOPTED JANUARY 26, 1998


This Executive Retention and Severance Plan (the "Plan" or "Retention Plan") was
adopted by the Compensation Committee of the Board of Directors of Bay Networks,
Inc. (the "Company") at a meeting held in Santa Clara, California on January 26,
1998, and approved and ratified by the full Board of Directors on January 27,
1998.

BACKGROUND OF THE PLAN

 A.   The Company draws upon the knowledge, experience and objective advice of
      its executives, managers and employees in order to manage its business for
      the benefit of the Company's stockholders.

 B.   Due to the widespread awareness of the possibility of mergers,
      acquisitions and other strategic alliances in the telecommunications and
      data networking industry, change of control is increasingly an issue in
      competitive recruitment efforts.

 C.   The Company recognizes that if there occurred a change of control or other
      event that could substantially change the nature and structure of the
      Company, the resulting uncertainty regarding the consequences of such an
      event could adversely affect the Company's ability to attract, retain and
      motivate its executives and key employees.

 D.   The Company initiated a project in October, 1997, to evaluate industry
      practices and possible standard approaches to the retention and severance
      of executives, officers and key employees in the event of a change of
      control of the Company.

 E.   On January 15, 1998, the Compensation Committee reviewed a market analysis
      and preliminary recommendations with respect to the adoption of an
      executive retention plan, prepared by a team including the Chief Financial
      Officer, counsel to the Company, counsel to the Committee and a
      compensation consultant.

 F.   On January 26, 1998, the Compensation Committee of the Company's Board of
      Directors reviewed, approved and adopted the general terms of the
      Retention Plan, and directed the Company's counsel to prepare definitive
      documentation of the Plan.

 G.   On January 27, 1998 the Retention Plan was approved and ratified by the
      Company's Board of Directors.

1.      GENERAL

        1.1 Purpose. The purpose of this Plan is to provide specified
compensation and benefits to selected Executives, Officers and Key Employees of
the Company in the event of a Termination Upon Change of Control.

        1.2 No employment agreement. This Agreement does not obligate the
Company to continue to employ a Plan Participant for any specific period of
time, or in any specific role or geographic location. Subject to the terms of
any applicable written employment agreement between Company and a Participant,
Company may assign a Participant to other duties, and either the Company or
Participant may terminate Participant's employment at any time for any reason.

        1.3 Defined terms. Capitalized terms used in this agreement shall have
the meanings set forth in section 4, unless the context clearly requires a
different meaning.

        1.4 Delivery of Agreements. The Executives of the Company are authorized
to deliver written Agreements confirming the provisions of this Plan. The
Company may elect not to deliver individual Agreements to each eligible Key
Employee, and shall not be required to deliver an individual agreement to every
Participant; however, the Company may condition a Participant's entitlement to
receive benefits under the Plan on execution of an Agreement.

        2.1 Basic Severance Compensation. In the event of a Participant's
Termination Upon Change of Control, the Participant shall be entitled to the

expenses reasonably and necessarily incurred by the Participant in connection
with the business of the Company prior to Participant's termination of
employment.

               2.1.3 Employee benefits. Participant shall receive the benefits,
if any, under the Company's 401(k) Plan, nonqualified deferred compensation
plan, employee stock purchase plan and other Company benefit plans to which

               2.2.1 Prorated bonus payment. A Participant who is an Executive

year in which termination occurs, pro rated through the date of termination and
less applicable withholding, paid within thirty (30) days of termination of
employment.

               2.2.2 Cash severance payment. A lump sum cash severance payment
shall be made:

         (a)   to each Participant who is a Key Employee, in the amount which is
               the greater of (1) one week (i.e., 0.01923) of Target Annual
               Earnings for every $10,000.00 of Target Annual Earnings, plus one
               week of Target Annual Earnings for every year of Participant's
               service to the Company (rounded to the closest year), or (2)
               thirteen weeks of Target Annual Earnings;

         (b)   to each Participant who is an Officer, in the amount of 125% of
               annual Target Annual Earnings; and

         (c)   to each Participant who is an Executive, in the amount of 200% of
               Target Annual Earnings.

All cash severance payments shall be reduced by applicable federal and state
withholding, and paid within thirty (30) days of termination of employment.

        2.3    Stock option acceleration.

               2.3.1  Acceleration at Termination Upon Change of Control.

                     (a) All outstanding stock options granted and restricted
stock issued by the Company to a Key Employee prior to the Change of Control
shall have their vesting accelerated as to one year of additional vesting as of
the date of such Termination Upon Change of Control.

                     (b) All outstanding stock options granted and restricted
stock issued by the Company to an Officer prior to the Change of Control shall
have their vesting accelerated as to two years of additional vesting as of the

                     (c) All outstanding stock options granted and restricted
stock issued by the Company to an Executive prior to the Change of Control shall
have their vesting fully accelerated so as to be 100% vested on the date of a
Termination Upon Change of Control.

               2.3.2 Acceleration upon non-assumption in a Change of Control. If
there is a Change of Control transaction in which outstanding stock options
granted and restricted stock issued by the Company prior to the transaction are
not fully assumed by the Successor, or replaced by fully equivalent substitute
options or restricted stock, then (1) all such options and restricted stock
shall have their vesting fully accelerated to be 100% vested prior to the
effective

date of the Change of Control and (2) the Company shall provide reasonable prior
written notice to Participant of (a) the date such unexercised options will
terminate and (b) the period during which Participant may exercise the fully
vested options. Alternatively, the Company may elect to deliver to Participant
on the effective date of the Change of Control a cash payment equal to the
difference between (i) the aggregate exercise price of Participant's unexercised
options or restricted stock, and (ii) the value of the consideration deliverable
for an equivalent number of shares as a result of the Change of Control
transaction.

        2.4    Extended medical and dental benefits.

               2.4.1 Benefit continuation. Participant shall receive continued
provision of the Company's standard employee medical and dental insurance
coverages, as elected by the Participant and in effect immediately prior to the
Change of Control, for the measuring period with respect to which Participant
receives a lump sum cash severance payment pursuant to section 2.2.2; plus, for
any Participant who is a consultant to the Company pursuant to section 2.5, an
additional six months.

               2.4.2 Continued medical coverage for U.S. residents. Thereafter,
if Participant resides in the United States, Participant shall be entitled to
elect continued medical insurance coverage in accordance with the applicable
provisions of U.S. federal law (COBRA). If such coverage included dependents of
Participant immediately prior to the date of termination, such dependents also
shall be covered at Company expense during the extension period. For purposes of
title X of the Consolidated Budget Reconciliation Act of 1985 ("COBRA"), the
date of the "qualifying event" for Participant and his dependents shall be the
date upon which the Company-paid coverage terminates.

               2.4.3 Termination upon coverage under another medical plan.
Notwithstanding the preceding provisions of this section 2.4, in the event a
Participant becomes covered as a primary insured (that is, not as a beneficiary
under a spouse's or partner's plan) under another employer's group health plan
during the continuation period, Participant promptly shall inform the Company
and the Company shall cease provision of continued group health insurance for
Participant and any dependents.

        2.5    Consulting contract.

               2.5.1 Six-month Consulting Period. If Participant is an
Executive, or an Officer who is either (a) designated as subject to the
reporting requirements of Section 16 of the Securities Exchange Act, or (b)
deemed an affiliate of the Company by the Company's legal counsel prior to a
change of control, then Participant shall be engaged as a consultant to the
Company for a period of six (6) months after Participant's Termination Upon
Change of Control (the "Consulting Period") to provide advice and assist in the
transition occasioned by the Change of Control.

               2.5.2 Consulting Fee. A Participant who is engaged as a
consultant pursuant to section 2.5.1 shall receive during the Consulting Period
a consulting fee in the

amount of fifty percent (50%) of Target Annual Earnings, payable in six equal
monthly installments.

               2.5.3 Option continuation during Consulting Period. The stock
options of a Participant entitled to be engaged as a consultant shall continue
in effect during the Consulting Period, in accordance with and to the maximum
extent permissible under the terms of the applicable option plans and
agreements.

               2.5.4 Other employment not precluded. During the Consulting
Period Participant shall not be precluded from accepting other employment,
provided Participant is available to the Company at such times and for such
consulting matters as the Company may reasonably request.

3.      FEDERAL EXCISE TAX UNDER IRC SECTION 280G

        3.1 Reimbursement of excise tax payable by an Executive. If (1) any
amounts payable under this Plan to an Executive are characterized as excess
parachute payments pursuant to Section 4999 of the Internal Revenue Code, and
(2) Executive thereby would be subject to any United States federal excise tax
due to that characterization, then (3) the Company shall reimburse the Executive
for the amount of such excise tax; provided, however, that, no reimbursement
shall be made for any excise tax payable with respect to the reimbursement made
pursuant to this section 3.1. The excise tax reimbursement made pursuant to this
section 3.1 shall be subject to all applicable withholding. The foregoing shall
be conditioned upon the Executive cooperating with the Company in such manner as
may be reasonably requested (other than reducing amounts payable hereunder) so
as to minimize the amount of such excise tax.

        3.2 Adjustment of excess payments payable to an Officer. If (1) any
amounts payable to an Officer under this Agreement are characterized as excess
parachute payments pursuant to Section 4999 of the Internal Revenue Code, and
(2) Officer thereby would be subject to any United States federal excise tax due
to that characterization, then (3) the Officer may elect, in Officer's sole
discretion, to reduce the amounts payable under this Agreement or to have any
portion of applicable options or restricted stock not vest in order to avoid any
"excess parachute payment" under Section 280G(b)(1) of the Internal Revenue Code
of 1986, as amended.

        3.3 Determination by independent public accountants. Unless the Company
and Participant otherwise agree in writing, any determination required under
this Section 3 shall be made in writing by independent public accountants agreed
to by the Company and the Participant (the "Accountants"), whose determination
shall be conclusive and binding upon Participant and the Company for all
purposes. For purposes of making the calculations required by this Section 3,
the Accountants may rely on reasonable, good faith interpretations concerning
the application of Sections 280G and 4999 of the Code. The Company and
Participant shall furnish to the Accountants such information and documents as
the Accountants may reasonably request in order to make the required
determinations. The Company shall bear all fees and expenses the
