                                                                  March 25, 1998




Dear Stockholder:

        A special meeting of stockholders will be held on Friday, April 24,
1998, at 4:00 p.m. local time, in the __________ room at the Company's principal
offices, 4401 Great America Parkway, Building __, ______ Floor, Santa Clara,
California. You are cordially invited to attend.

        We are submitting two proposals for stockholder approval in response to
a recent interpretation of financial accounting rules. The first proposal
increases the number of shares reserved for issuance under our 1994 Employee
Stock Purchase Plan by 2,000,000. The second proposal establishes a new 1998
Employee Stock Purchase Plan, and reserves 500,000 additional shares for
issuance under the new plan; upon approval, the 1998 plan is intended to
supersede the old plan for all new enrollments. As is more fully described in
the Proxy Statement, these proposals are designed to limit the future dilutive
impact of employee stock purchases, and to lessen the likelihood that the
Company will be required to record future compensation charges related to
employee stock purchases.

        The third proposal, to increase the number of authorized shares of
Common Stock of the Company, is intended primarily to provide additional Common
Stock for possible future use by the Company in acquiring new businesses and
technologies.

        The Notice of Special Meeting of Stockholders and a Proxy Statement,
which describe in detail the business to be conducted at the meeting, follow
this letter.

        After reading the Proxy Statement, please promptly vote your shares.
Your shares cannot be voted unless you date, sign, and return the enclosed proxy
card or attend the special meeting in person. If you are a stockholder of
record, you can vote your shares electronically or by telephone as described in
the yellow flyer enclosed with your materials. If your shares are held in the
name of a bank or broker, you may be able to vote electronically or by
telephone; follow the instructions on the form you receive from your bank or
broker. Regardless of the number of shares you own, your careful consideration
of, and vote on, the matters before our stockholders is important.

        We appreciate your interest and participation as a stockholder of Bay
Networks.

                                           Very truly yours,





                                           DAVID L. HOUSE
                                           Chairman of the Board,
                                           President and Chief Executive Officer

               PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS

        The accompanying proxy is solicited by the Board of Directors of Bay
Networks, Inc., a Delaware corporation ("Bay Networks" or the "Company"), for
use at a special meeting of stockholders to be held on April 24, 1998, or any
adjournment or postponement, for the purposes set forth in the accompanying
Notice of Special Meeting of Stockholders. The date of this Proxy Statement is
March 25, 1998, the approximate date on which this Proxy Statement and the
accompanying form of proxy were first sent or given to stockholders.

                       SOLICITATION AND VOTING OF PROXIES

        The cost of soliciting proxies will be borne by the Company. In addition
to soliciting stockholders by mail through its employees, the Company will
request banks and brokers, and other custodians, nominees and fiduciaries, to
solicit their customers who have stock of the Company registered in the names of
such persons and will reimburse them for their reasonable, out-of-pocket costs.
The Company may use the services of its officers, directors and others to
solicit proxies, personally or by telephone, without additional compensation. In
addition, the Company has retained Corporate Investor Communications, Inc. for
assistance with the distribution of proxy materials in connection with the
special meeting at a cost of approximately $5,000, plus reasonable out-of-pocket
expenses.

        On March 9, 1998, the Company had outstanding [ ] shares of its Common
Stock, par value $0.01 per share ("Common Stock"), all of which are entitled to
vote with respect to all matters to be acted upon at the special meeting. Each
stockholder of record as of that date is entitled to one vote for each share of
Common Stock held by him or her. The Company's Bylaws provide that a majority of
all of the shares of the stock entitled to vote, whether present in person or
represented by proxy, shall constitute a quorum for the transaction of business
at the meeting. Votes for and against, abstentions and "broker non-votes" will
each be counted as present for purposes of determining the presence of a quorum.

        All valid proxies received before the meeting will be exercised. All
shares represented by a proxy will be voted, and where a stockholder specifies
by means of his or her proxy a choice with respect to any matter to be acted
upon, the shares will be voted in accordance with the specification so made. If
no choice is indicated on the proxy, the shares will be voted in favor of the
proposal. A stockholder giving a proxy has the power to revoke his or her proxy
at any time before the time it is exercised by delivering to the Secretary of
the Company a written instrument revoking the proxy or a duly executed proxy
with a later date, or by attending the meeting and voting in person. A
stockholder who can vote electronically or by telephone can revoke his or her
proxy by voting his or her proxy in accordance with the instructions included
with the stockholder's materials.

(1)      Potential gains are net of exercise price, but before taxes associated
         with exercise. These amounts represent certain assumed rates of
         appreciation only, based on the Securities and Exchange Commission
         rules. Actual gains, if any, on stock option exercises are dependent on
         the future performance of the Common Stock, overall market conditions
         and the option holders' continued employment through the vesting
         period. The amounts reflected in this table may not necessarily be
         achieved.

(2)      Except as described in footnotes 5, 6, 7 and 9 below, all options
         granted in fiscal 1997 under the 1994 Option Plan are immediately
         exercisable but vest over a four-year period from the date of grant.
         Those options vesting over a four-year period generally vest at the
         rate of one-fourth on the first anniversary of the date of grant and
         1/48th per month thereafter for each full month of the optionee's
         continuous employment with the Company. Under the 1994 Option Plan, the
         Board retains discretion to modify the terms, including the prices, of
         outstanding options. For additional information regarding options, see
         "Severance, Employment and Change of Control Arrangements."

(3)      All options were granted at market value on the date of grant.

(4)      Represents an option granted outside of the 1994 Option Plan that is
         immediately exercisable but vests at the end of a one-year period from
         the date of grant. The term of the option is 18 months, subject to
         automatic ongoing extensions. See "Severance, Employment and Change of
         Control Arrangements."

(5)      Represents performance-based stock options ("Performance Stock
         Options") granted to certain executive officers in July 1996 under the
         1994 Option Plan. Performance Stock Options generally vest over six
         years at five percent per year from the date of grant for each of the
         first three years, and twenty percent, thirty percent and thirty-five
         percent over years four, five, and six, respectively, rather than over
         a conventional four-year vesting schedule. Performance Stock Option
         vesting may be incrementally accelerated in accordance with the
         judgment of the Board or the Chief Executive Officer, as appropriate,
         based on the recipient's achievement of specified performance goals.

(6)      Represents an option granted under the 1994 Option Plan which vests at
         the rate of 300,000 one year from the date of grant and 1/36th per
         month thereafter for each month of Mr. Shrigley's continuous employment
         with the Company. See "Severance, Employment and Change of Control
         Arrangements."

(7)      Represents options that were repriced on October 28, 1996, replacing
         options that were granted in fiscal 1996 and 1997.

(8)      Following the resignation of Mr. Ludwick as an executive officer of the
         Company, Mr. Ludwick continued as an employee of the Company and
         received continued vesting under the terms of his stock option
         agreements until August 1997. See "Severance, Employment and Change of
         Control Arrangements."

(9)      Represents Performance Stock Options that will vest at five percent per
         year during fiscal 1998 and fiscal 1999 until the termination of Mr.
         Sachs' employment in May 1999. See "Severance, Employment and Change of
         Control Arrangements." Shares that will be forfeited after his
         termination date are not reflected in the stock price appreciation
         amounts shown in the table.

OPTION EXERCISES AND FISCAL 1997 YEAR-END VALUES

        The following table provides the specified information concerning
exercises of options to purchase the Company's Common Stock in the fiscal year
ended June 30, 1997, and unexercised options held as of June 30, 1997, by the
persons named in the Summary Compensation Table above. A portion of the shares
subject to these options are not yet vested, and thus would be subject to
repurchase by the Company at a price equal to the option exercise price, if the
corresponding options were exercised before those shares had vested.

SEVERANCE, EMPLOYMENT AND CHANGE OF CONTROL ARRANGEMENTS

        In October 1996, the Company entered into an Employment Agreement with
David House, the Chairman of the Board, President and Chief Executive Officer of
the Company (the "House Agreement"), effective on October 30, 1996 (the "House
Effective Date"). The House Agreement provides for the payment to Mr. House of a
$500,000 minimum base annual salary and a $1,000,000 bonus for the Company's
1997 fiscal year, subject to the Board of Directors' review in subsequent years.
Pursuant to the House Agreement, Mr. House was granted an option under the 1994
Option Plan to purchase 1,500,000 shares of the Company's Common Stock and an
additional option to purchase 500,000 shares of the Company's Common Stock. See
"OPTION GRANTS IN LAST FISCAL YEAR" table. The House Agreement also provides for
the following severance benefits if Mr. House's employment with the Company
terminates involuntarily or if Mr. House terminates his employment with the
Company voluntarily for "Good Reason": (a) a lump sum payment equal to 12 months
of Mr. House's then effective base salary, plus 100% of Mr. House's target bonus
for the year in which termination occurs, plus an additional bonus equal to a
percentage (which may exceed 100%) of the bonus target amount for the year in
which termination occurs, (b) one year's additional vesting as of the date of
termination for any outstanding stock options and any stock subject to
restricted stock purchase agreements ("restricted stock"), (c) one year's
additional vesting for Mr. House's accounts under any deferred compensation
plans or arrangements, and (d) the continuation of Company-paid benefits for up
to one year. In the event of a change of control of the Company, the vesting of
any outstanding stock options or restricted stock will be accelerated by one
additional year. The House Agreement further provides for a tax gross-up payment
to mitigate the effect of any excise tax imposed under the "parachute"
provisions of the Internal Revenue Code of 1986, as amended (the "Code"). In
addition, if Mr. House dies or becomes partially or permanently disabled while
employed by the Company and the Company takes any action that would constitute
"Good Reason" for Mr. House to voluntarily terminate his employment, then Mr.
House's unvested options and restricted stock become fully vested.

        In March 1997, the Company entered into a letter agreement with Lloyd
Carney, the Company's Executive Vice President and General Manager, Enterprise
Business Group, (the "Carney Agreement") which provides for an annual base
salary of $250,000 and a target bonus of $200,000, prorated from January 22,
1997 through the end of fiscal 1997. The Carney Agreement also provides for the
grant of a stock option to purchase 115,000 shares of the Company's Common
Stock. See "OPTION GRANTS IN LAST FISCAL YEAR" table. Pursuant to the Carney
Agreement, the Company also paid Mr. Carney's relocation expenses in connection
with his relocation to California and sales commission and non-recurring closing
costs associated with the sale of his Massachusetts home. The Company also
agreed to pay certain expenses upon a return move to Massachusetts in the next
five years, unless Mr. Carney voluntarily resigns or is terminated for cause. In
addition, the Company agreed to provide housing assistance in the form of
annualized interest cost reimbursement for the additional mortgage for a primary
residence in California for a period of three years. If a change in management
causes the termination of Mr. Carney's employment with the Company, the Company
agreed to continue such mortgage assistance until the earlier of six months
after the termination date or the date Mr. Carney finds other employment. In
addition, the Company loaned Mr. Carney an aggregate of $416,450, without
interest, in connection with the purchase of a primary residence in California;
this loan has been repaid.

        In November 1997, the Company entered into another letter agreement with
Mr. Carney (the "Additional Carney Agreement") which, among other things,
provides for the grant of additional stock options under the 1994 Option Plan to
purchase, at $28.125 per share, an aggregate of 130,000 shares of the Company's
Common Stock. Such options vest with respect to 15,000 shares on January 3,
1998, 15,000 shares on January 3, 1999, 23,700 shares on January 3, 2000 and
76,300 shares on January 3, 2001. The Additional Carney Agreement also revises
the vesting schedule for a Performance Stock Option granted to Mr. Carney in
July 1996 to purchase 100,000 shares of the Company's Common Stock so that such
option vests without regard to the determination and achievement of performance
goals at a rate of 15,480 shares on January 3, 1998, 28,000 shares on January 3,
1999, and 44,300 shares on January 3, 2000. See "OPTION GRANTS IN LAST FISCAL
YEAR" table. The Company also agreed to pay to Mr. Carney a special bonus, if
Mr. Carney remains employed by the Company on January 3, 2001, equal to
$1,130,146 minus the value of the appreciation on 60,000 shares of his vested
stock at such time over the $28.125 exercise price. In addition, if Mr. Carney's
employment with the Company terminates as a result of disability or death, Mr.
Carney (or his heirs and/or beneficiaries) would receive (i) a lump sum payment
equal to 12 months of his base salary, (ii) payment of an amount equal to Mr.
Carney's target annual bonus for the fiscal year in which Mr. Carney's
disability or death occurs and (iii) full vesting for Mr. Carney's outstanding
stock options.

        In December 1996, the Company entered into a letter agreement with David
Rynne, the Company's Executive Vice President and Chief Financial Officer, (the
"Rynne Agreement") pursuant to the commencement of Mr. Rynne's employment with
the Company. The Rynne Agreement provides for an annual base salary of $450,000
and a minimum bonus of $225,000 for fiscal 1997, prorated for the number of days
he was employed by the Company in fiscal 1997. The Rynne Agreement also provides
for the grant of a stock option to purchase 400,000 shares of the Company's
Common Stock. See "OPTION GRANTS IN LAST FISCAL YEAR" table. In the event of a
change of control of the Company that results in a significant reduction of Mr.
Rynne's duties or responsibilities, Mr. Rynne is entitled to receive one year's
base salary and bonus and an acceleration of vesting of any outstanding stock
options and restricted stock by one year. In addition, if Mr. Rynne remains
employed by the Company for three years or in the event of termination other
than for cause or upon a change of control of the Company, he is entitled to
receive a special bonus equal to $2,000,000 minus the value of the appreciation
on his vested shares at such time. If Mr. Rynne is terminated by the Company
other than for due cause, he is entitled to receive 12 months' worth of his base
salary, bonus and additional vesting after his termination date.

        In November 1996, the Company entered into an Employment Agreement with
David Shrigley, the Executive Vice President for Sales, Service and Marketing of
the Company, (the "Shrigley Agreement") effective on November 6, 1996 (the
"Shrigley Effective Date"). The Shrigley Agreement provides for the payment to
Mr. Shrigley of a $250,000 minimum base annual salary and a $300,000 bonus for
the Company's 1997 fiscal year, prorated for the number of days employed in
fiscal 1997, subject to Board of Directors' review in subsequent years. The
Shrigley Agreement also provides for the grant of a stock option to purchase
600,000 shares of the Company's Common Stock. See "OPTION GRANTS IN LAST FISCAL
YEAR" table. In addition, pursuant to the Shrigley Agreement, the Company paid
Mr. Shrigley an additional bonus of $250,000 in fiscal 1997 to replace his 1996
executive bonus from his previous employer. If Mr. Shrigley remains employed by
the Company two years following the Shrigley Effective Date, the Shrigley
Agreement provides for the payment of a bonus equal to $2,300,000 minus the
value of the appreciation on his vested shares at such time (the "Second
Anniversary Bonus"). The Second Anniversary Bonus is subject to modification
under certain circumstances in the event of Mr. Shrigley's death or disability,
upon the termination of Mr. Shrigley's employment under certain circumstances or
upon a change of control of the Company. Under the Shrigley Agreement, the
Company has loaned Mr. Shrigley $542,167, an amount sufficient to retire Mr.
Shrigley's outstanding loan with his previous employer. The loan from the
Company bears interest at the rate of 6% per annum. The principal amount plus
accrued interest is secured by a deed of trust on Mr. Shrigley's principal
residence and is payable on the earlier of June 9, 2000, the sale or refinancing
of Mr. Shrigley's principal residence or the termination of Mr. Shrigley's
employment by the Company. The Shrigley Agreement provides the same severance
and "change of control" arrangements as the House Agreement. In addition, Mr.
Shrigley's severance benefits provide that he would receive the Second
Anniversary Bonus to the extent not already received. Finally, if Mr. Shrigley
dies or becomes partially or permanently disabled while employed by the Company
and the Company takes any action that would constitute "Good Reason" for Mr.
Shrigley to terminate his employment, then Mr. Shrigley's unvested options and
restricted stock become fully vested and Mr. Shrigley shall be entitled to the
Second Anniversary Bonus.

        On January 26, 1998, the Compensation Committee of the Board of
Directors approved the terms of an Executive Retention and Severance Plan (the
"Retention Plan"). Under the Retention Plan, specified officers and key
contributors are eligible to receive severance benefits if both conditions of a
"double trigger" occur: (1) there is a change of control of the Company, and (2)
within 12 months after a change of control either the individual's employment is
involuntarily terminated other than for cause, or the individual terminates his
or her employment for "Good Reason." The Company intends to implement the Plan
by providing formal written agreements ("Retention Agreements") to each of the
specified individuals, specifying the terms, conditions and benefits provided
under the Retention Plan. Specified benefits will not be payable in connection
with a change of control under both a Retention Agreement and an individual
employment agreement, and each eligible individual must elect to receive either
the benefits provided by the Retention Agreement or the benefits provided under
another agreement.

        The Retention Agreements will provide that if both of the "double
trigger" conditions occur, Messrs. House, Carney, Rynne and Shrigley each shall
be entitled to receive (a) a lump sum cash payment equal to two times the
officer's "Target Annual Earnings," consisting of the sum of (i) then effective
annual base salary, plus (ii) 100% of the annual incentive target for the year
in which termination occurs; (b) full accelerated vesting 



                                       12
<PAGE>   17

of any options to purchase shares of the Company's Common Stock, or any unvested
shares of restricted stock; and (c) reimbursement of any excise tax payable
under Internal Revenue Code Section 280G, other than any 280G excise tax payable
with respect to the reimbursement. The Retention Agreement provided to Mr. Seim
provides that if both of the "double trigger" conditions occur, he shall be
entitled to receive (a) a lump sum cash payment equal to 1.25 times his "Target
Annual Earnings," (b) two years of accelerated vesting of any options to
purchase shares of the Company's Common Stock, or any unvested shares of
restricted stock, and (c) in the event that any payment under the Retention
Agreement is subject to excise tax pursuant to Internal Revenue Code Section
280G, the right to reduce such payments in order to avoid all or part of the
excise tax. The Retention Agreements for each of the officers named above also
include a six-month consulting contract which provides for payment over the term
of the contract at a rate equal to the officer's Target Annual Earnings.

        On January 23, 1997, pursuant to a letter (a "Founder's Letter") from
the Company to each of Andrew K. Ludwick and Paul J. Severino, each a director
of the Company and the former President and Chief Executive Officer and the
former Chairman of the Board and Acting Chief Executive Officer, respectively
(each, a "Founder"), in connection with the Founder's resignation as an
executive officer of the Company, the Company agreed that each Founder would
continue as an employee of the Company through June 30, 1997 and for such time
thereafter as the Founder expended any accrued vacation (the "Founder
Termination Date"). The Founder Termination Date for each Founder occurred in
August 1997. Each Founder's Letter also provides that, until the Founder
Termination Date, the Founder will continue to receive his then current base
salary, continued vesting under the terms of his stock option agreements,
standard employee benefits, and the opportunity to participate in the 1994
Employee Stock Purchase Plan. Each Founder's Letter further provides that the
Founder would receive no bonus for fiscal 1997.

        In November 1996, the Company entered into a letter agreement which
modified an employee retention agreement between Bruce I. Sachs, the Company's
former Executive Vice President, Internet/Telecom Business Unit, and the Company
which was entered into upon the acquisition of Xylogics, Inc. on December 15,
1995 (the "Sachs Agreement"). If, at any time prior to June 30, 1997, the
Company notified Mr. Sachs of its intention to terminate his employment other
than for "Cause" or Mr. Sachs notified the Company of his intention to terminate
his employment for "Good Reason," Mr. Sachs would become entitled to his full
monthly base salary and benefits (excluding any car allowance and any
entitlement to participate on any basis in any bonus plans) until the earlier of
(i) the date 24 months from the date of the notice of termination or (ii) the
date on which Mr. Sachs commences employment with certain competitors of Bay
Networks. In addition, Mr. Sachs would receive a bonus for fiscal 1997, pro
rated for the number of days during fiscal 1997 which have elapsed as of the
date of termination. Such payments may be reduced to the extent they would be
nondeductible by the Company pursuant to Section 280G of the Code. Mr. Sachs is
also subject to certain non-competition and non-solicitation provisions for a
period of one year after termination of employment. Mr. Sachs' employment with
the Company terminated in May 1997. As a result, Mr. Sachs is entitled to
receive the severance benefits as described above.

        In February 1997, Bay Networks entered into an agreement with Richard
Eyestone, the Company's Senior Vice President, Product and Market Management,
Enterprise Business Unit, (the "Eyestone Agreement") in connection with the
relinquishment of Mr. Eyestone's role as an executive officer of the Company.
The Eyestone Agreement provides that Mr. Eyestone will be employed on a
half-time basis beginning April 1, 1997, and will continue as an employee of the
Company until April 1, 1998, at which time the Eyestone Agreement will be
reevaluated. During the term of the Eyestone Agreement, the Company will
continue his $200,000 base salary and he will be eligible for his fiscal 1997
bonus. He will be able to participate in the 1994 Option Plan and other employee
benefits for a period of one year. In addition, the Company agreed to pay all of
Mr. Eyestone's expenses in connection with his relocation to the southeastern
United States.

        Options granted to officers of Bay Networks under its 1994 Option Plan
provide that such officers will receive an advancement of the vesting schedule
by 12 months under certain circumstances upon a "change of control" as defined
under the 1994 Option Plan.

        Options granted to officers of SynOptics under the SynOptics 1986 Option
Plan also provided that such officers would receive an advancement of the
vesting schedule by 12 months under certain circumstances upon a 



                                       13
<PAGE>   18

"change of control" as defined in the SynOptics 1986 Option Plan. The Merger
constituted a "change of control" for SynOptics, therefore, the vesting schedule
of outstanding options granted to officers of SynOptics under the SynOptics 1986
Option Plan was advanced by 12 months upon the Merger. All outstanding options
granted under the SynOptics 1986 Option Plan were assumed by the Company in
connection with the Merger.

COMPENSATION OF DIRECTORS

        The Company's non-employee directors receive $1,500 for each meeting of
the Board of Directors they attend and $1,000 for each committee meeting they
attend. In addition, each non-employee director receives an annual retainer of
$21,000. During the 1997 fiscal year, each of the Company's non-employee
directors also received an option to purchase 15,000 shares of the Company's
Common Stock under the Company's 1994 Outside Directors Stock Option Plan. The
Company's directors who are also officers of the Company did not receive any
compensation for their services as members of the Board of Directors.

CHANGES TO BENEFIT PLANS

        1994 Purchase Plan. The Board of Directors of the Company has adopted,
subject to stockholder approval, an amendment to the 1994 Employee Stock
Purchase Plan (the "1994 Purchase Plan") to increase the maximum number of
shares that may be issued under the 1994 Purchase Plan by 2,000,000 shares, from
5,250,000 shares to 7,250,000 shares. See "APPROVAL OF AMENDMENT TO THE BAY
NETWORKS, INC. 1994 EMPLOYEE STOCK PURCHASE PLAN" at page 16 of this Proxy
Statement. As of March 25, 1998, no purchases had been made by any employee
conditioned on stockholder approval of an increase in the share reserve under
the 1994 Purchase Plan. Non-employee directors are not eligible to participate
in the 1994 Purchase Plan.

        1998 Purchase Plan. The Board of Directors of the Company has adopted,
subject to stockholder approval, the 1998 Employee Stock Purchase Plan (the
"1998 Purchase Plan") with an initial share reserve of (a) 500,000 shares, plus
(b) any shares remaining available for issuance under the 1994 Employee Stock
Purchase Plan that are not required to complete offerings currently in progress,
up to a maximum of 5,000,000 shares. See "APPROVAL OF ADOPTION OF THE BAY
NETWORKS, INC. 1998 EMPLOYEE STOCK PURCHASE PLAN" at page 19 of this Proxy
Statement. As of March 25, 1998, no purchases had been made by any employee
conditioned on stockholder approval of the 1998 Purchase Plan. Non-employee
directors are not eligible to participate in the 1998 Purchase Plan.

        The following table sets forth purchases of shares of stock under the
1994 Purchase Plan during the fiscal year ended June 30, 1997, by (1) the
persons named in the Summary Compensation Table above; (2) all current executive
officers as a group; (3) all current directors who are not executive officers as
a group; and (4) all employees, including all officers who are not executive
officers, as a group. Purchases under the 1994 Purchase Plan and the 1998
Purchase Plan are made at the discretion of participating employees.
Accordingly, future purchases under the 1994 and 1998 Purchase Plans are not yet
determinable.

                APPROVAL OF AMENDMENT TO THE BAY NETWORKS, INC.
                       1994 EMPLOYEE STOCK PURCHASE PLAN

IMPORTANCE OF STOCK PURCHASE PLAN AS AN EMPLOYEE BENEFIT

        The Company believes that the availability of an adequate reserve of
shares available for issuance under the 1994 Purchase Plan will benefit the
Company by providing employees with an opportunity to acquire shares of the
Company's Common Stock and will enable the Company to continue to attract,
retain and motivate eligible employees. As of March 25, 1998, 2,351,981 shares
of Common Stock remained available for issuance under the 1994 Purchase Plan.

RECENT ACCOUNTING CHANGES

        A recent interpretation of generally accepted accounting
principles require the Company to record a charge to earnings if certain
conditions apply to an employee stock purchase plan that qualifies under Section
423 of the Internal Revenue Code. This interpretation was announced in September
1997 in the consensus issued by the Emerging Issues Task Force entitled
Accounting for Increased Share Authorizations in an IRS Section 423 Employee
Stock Purchase Plan under APB Opinion No. 25, Accounting for Stock Issued to
Employees (Issue No. 97-12) ("EITF 97-12"). Generally, if (i) at the beginning
of an offering period, the shares reserved for issuance under an employee stock
purchase plan are insufficient to cover all shares issuable throughout the
offering period, (ii) stockholders subsequently approve additional shares
allocable to an offering period which commenced prior to the stockholder
approval date, and (iii) the fair market value of the stock subject to the plan
on the subsequent stockholder approval date is higher than the fair market value
on the date when the offering period commenced, then the Company will be
required to record a charge to earnings to reflect the theoretical compensatory
element of the difference in fair market value.

        Under prior practice, the Company typically would seek stockholder
approval for additional shares when the shares remaining under the 1994 Purchase
Plan appeared insufficient for a 12-month time frame. However, the 1994 Purchase
Plan provides for 24-month Offering Periods (defined on page 17) consisting of
four six-month Purchase Periods (defined on page 17) and a new Offering Period
begins every six months. Applied to this structure, the treatment specified by
EITF 97-12 would require that, in order to avoid a potential earnings charge,
the number of shares reserved for issuance under the 1994 Purchase Plan must
never decline below a level required to maintain at least 24 months of
projected purchases. 

        Two variables that may affect the amount of an earnings charge required
under EITF 97-12 are substantial hiring rates, which affect new enrollments to
the plan, and increases over time in the market value of the Company's Common
Stock. As a result of this accounting interpretation, the Company expects to
recognize, for the 1994 Purchase Plan Offering Period commenced in May 1997, a
non-cash charge which will be amortized over the remaining fiscal quarters of
the Offering Period. The impact on basic and fully diluted earnings per share is
expected to be approximately $0.01 per share for the quarter ending March 28,
1998 and for each of the remaining fiscal quarters in the Offering Period.

MANAGEMENT PROPOSALS TO AMEND THE 1994 PURCHASE PLAN AND ADOPT THE 1998 PURCHASE
PLAN

        In order to minimize the possibility or extent of such charges in the
future and, in particular, to avoid a charge relating to the Offering Period
scheduled to commence in May 1998, and to decrease the future dilutive impact of
employee stock purchases through Company sponsored plans, Management is
requesting stockholder approval to amend the 1994 Purchase Plan now, rather than
wait until the Company's Annual Meeting of Stockholders in October 1998. In
addition, Management is also requesting stockholder approval of a new 1998
Employee Stock Purchase Plan, described below under "APPROVAL OF ADOPTION OF THE
BAY NETWORKS, INC. 1998 EMPLOYEE STOCK PURCHASE PLAN." The 1998 Purchase Plan
provides for shorter six-month offering periods in order to minimize the future
likelihood of earnings charges relating to EITF 97-12 and to make the plan
easier to administer. At a meeting held on ______________, 1998,



                                       16
<PAGE>   21

the Board of Directors unanimously adopted, subject to stockholder approval
being received at the special meeting, an amendment to increase the number of
shares reserved for issuance under the 1994 Purchase Plan by 2,000,000 shares to
a total of 7,250,000 shares.

SUMMARY OF THE PROVISIONS OF THE 1994 PURCHASE PLAN

        The following summary of the 1994 Purchase Plan is qualified in its
entirety by the specific language of the 1994 Purchase Plan, a copy of which is
available to any stockholder upon request.

        Any employee of Bay Networks or any present or future parent or
subsidiary corporation of Bay Networks (including any director who is also an
employee) is eligible to participate in the 1994 Purchase Plan so long as the
employee is customarily employed for more than 20 hours per week and for more
than five months in a calendar year and the employee is not a participant in any
other employee stock purchase plan maintained by Bay Networks or any parent or
subsidiary corporation of Bay Networks. No person who owns or holds options to
purchase or as a result of participation in the 1994 Purchase Plan would own or
hold options to purchase, 5% or more of the total combined voting power or value
of all classes of stock of Bay Networks is entitled to participate in the 1994
Purchase Plan. As of January 31, 1998, approximately 6,165 employees were be
eligible to participate in the 1994 Purchase Plan.

        Each offering of Common Stock under the 1994 Purchase Plan is for a
period of 24 months (an "Offering Period"). Offering Periods are overlapping,
with a new 24-month Offering Period beginning every six months. New Offering
Periods begin on each May 1 and November 1. Subject to stockholder approval of
the 1998 Purchase Plan, the Board of Directors has determined that no Offering
Periods will begin under the 1994 Purchase Plan after April 24, 1998. Each
Offering Period is comprised of four six-month "Purchase Periods." Shares are
purchased on the last business day of each Purchase Period, in April and October
("Purchase Dates"). The Board of Directors may establish different Offering
Periods or Purchase Periods under the 1994 Purchase Plan.

        Participation in the 1994 Purchase Plan is limited to eligible employees
who authorize payroll deductions pursuant to the 1994 Purchase Plan. Such
payroll deductions must be at least 1% but may not exceed 10% of an employee's
compensation. Currently, the maximum amount of payroll deductions for any
participants during a six-month Purchase Period is $5,040. However, the Board of
Directors, in its discretion, may provide for a different limit on payroll
deductions for an Offering Period. Once an employee becomes a participant in the
1994 Purchase Plan, that employee will automatically participate in each
successive offering until such time as that employee (a) withdraws from the 1994
Purchase Plan, (b) becomes ineligible to participate in the 1994 Purchase Plan,
or (c) terminates his or her employment, although, as described above, no
additional Offering Periods will commence after April 24, 1998 under the 1994
Purchase Plan if the stockholders approve the 1998 Purchase Plan.

        A participant will purchase shares at the end of each of four Purchase
Periods within an Offering Period. The purchase price per share will be equal to
85% of the lesser of the fair market value of the Common Stock on the first day
of the Offering Period or on the Purchase Date. If the fair market value of the
Common Stock on a Purchase Date (other than the last Purchase Date of an
Offering Period) is less than its fair market value on the first day of the
Offering Period, then (unless a participant otherwise elects) all participants
will automatically be withdrawn from that offering and enrolled in the new
Offering Period, although, as described above, no additional Offering Periods
will commence after April 24, 1998 under the 1994 Purchase Plan if the
stockholders approve the 1998 Purchase Plan.

        Subject to certain limitations, the number of shares of Bay Networks
Common Stock a participant purchases in each Purchase Period is determined by
dividing the total amount of payroll deductions withheld from the participant's
compensation during the Purchase Period by the purchase price per share. Any
cash not applied to the purchase of shares will be returned to the participant
unless the amount of such cash is less than the amount necessary to purchase a
whole share of Common Stock, in which case Bay Networks may establish procedures
to apply the remaining amount to a subsequent Offering Period or Purchase
Period.



                                       17
<PAGE>   22

        An employee who remains eligible to participate in the 1994 Purchase
Plan may nevertheless withdraw from an offering at any time without affecting
his or her eligibility to participate in future offerings, although, as
described above, no additional offerings will commence under the 1994 Purchase
Plan if the stockholders approve the 1998 Purchase Plan. In effect, therefore, a
participant is given an option which he or she may or may not exercise. However,
once a participant withdraws from an offering, that participant may not again
participate in the same offering.

        The Board of Directors may at any time amend or terminate the 1994
Purchase Plan, except that the approval of Bay Networks' stockholders is
required within 12 months of the adoption of any amendment increasing the number
of shares authorized for issuance under the 1994 Purchase Plan, or changing the
definition of the corporations which may be designated by the Board as
corporations whose employees may purchase shares of Bay Networks Common Stock
under the 1994 Purchase Plan. As described above, subject to stockholder
approval of the 1998 Purchase Plan, no additional Offering Periods will commence
after April 24, 1998 under the 1994 Purchase Plan, although participants who
enrolled in the Offering Periods beginning in May and November 1997 are entitled
to continue their enrollments until those Offering Periods expire.

SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

        The following summary is intended only as a general guide as to the
United States federal income tax consequences under current law of participation
in the 1994 Purchase Plan and does not attempt to describe all potential tax
consequences. Furthermore, the tax consequences are complex and subject to
change, and a taxpayer's particular situation may be such that some variation of
the described rules is applicable. A participant recognizes no taxable income
either as a result of commencing to participate in the 1994 Purchase Plan or
purchasing shares of Bay Networks Common Stock under the terms of the 1994
Purchase Plan.

        If a participant disposes of shares purchased under the 1994 Purchase
Plan within two years from the first day of the applicable Offering Period or
within one year from the Purchase Date (a "disqualifying disposition"), the
participant will realize ordinary income in the year of such disposition equal
to the amount by which the fair market value of the shares on the date the
shares were purchased exceeds the purchase price. The amount of the ordinary
income will be added to the participant's basis in the shares, and any
additional gain or resulting loss recognized on the disposition of the shares
will be a capital gain or loss. A capital gain or loss will be long-term if the
participant's holding period is more than 12 months, otherwise it will be
short-term.

        If the participant disposes of shares purchased under the 1994 Purchase
Plan at least two years after the first day of the applicable Offering Period
and at least one year after the date of purchase, the participant will realize
ordinary income in the year of disposition equal to the lesser of (i) the excess
of the fair market value of the shares on the date of disposition over the
purchase price or (ii) 15% of the fair market value of the shares on the first
day of the applicable Offering Period. The amount of any ordinary income will be
added to the participant's basis in the shares, and any additional gain
recognized upon the disposition after such basis adjustment will be a long-term
capital gain. If the fair market value of the shares on the date of disposition
is less than the purchase price, there will be no ordinary income and any loss
recognized will be a long-term capital loss.

        If the participant still owns the shares at the time of death, the
lesser of (i) the excess of the fair market value of the shares on the date of
death over the purchase price or (ii) 15% of the fair market value of the shares
on the first day of Offering Period in which the shares were purchased will
constitute ordinary income in the year of death.

        Bay Networks will generally be entitled to a tax deduction in the year
of a disqualifying disposition equal to the amount of ordinary income recognized
by the participant as a result of disposition. In all other cases, no deduction
is allowed by Bay Networks.

VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION

        The affirmative vote of a majority of the votes cast on the proposal, at
the special meeting at which a quorum representing a majority of all outstanding
shares of Common Stock of the Company is present, either in person or by proxy,
is required for approval of this proposal. Votes for and against, abstentions
and broker non-votes will each be counted as present for purposes of determining
the presence of a quorum. Abstentions will have the same effect as a negative
vote on this proposal. Broker non-votes will have no effect on the outcome of
this vote.

        The Board believes that the proposed amendment of the 1994 Purchase Plan
is in the best interests of the Company and its stockholders for the reasons
stated above. THEREFORE, THE BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" APPROVAL
OF THIS PROPOSAL TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK OF THE COMPANY
RESERVED FOR ISSUANCE UNDER THE 1994 PURCHASE PLAN BY 2,000,000 SHARES, FROM
5,250,000 SHARES TO 7,250,000 SHARES.

                 APPROVAL OF ADOPTION OF THE BAY NETWORKS, INC.
                        1998 EMPLOYEE STOCK PURCHASE PLAN

        The Company believes that the adoption of the 1998 Purchase Plan will
benefit the Company by providing employees with an opportunity to acquire shares
of the Company's Common Stock and will enable the Company to attract, retain and
motivate eligible employees.

        The Company believes that the six-month Offering Period (defined on page
20) in the 1998 Purchase Plan is more consistent with competitive practices than
the 24-month Offering Period provided in the 1994 Purchase Plan. In addition to
provisions designed to minimize the effect of the accounting interpretation
changes described on page 16, the 1998 Purchase Plan includes provisions that
are intended to make the 1998 Purchase Plan more efficient to administer.
Moreover, Management believes that if the market price of the Company's stock
appreciates over time, the 1998 Purchase Plan will require the issuance of fewer
shares that would be issued under the 1994 Purchase Plan over a comparable
multi-year period.

        At a meeting held on _______________, 1998, the Board of Directors
unanimously adopted the 1998 Purchase Plan, subject to stockholder approval
being received at the special meeting. The maximum number of shares of Common
Stock that may be issued under the 1998 Purchase Plan is equal to the sum of (a)
500,000 shares, plus (b) the remaining number of shares of Common Stock
available for issuance under the 1994 Purchase Plan that are not required to
complete all offerings under the 1994 Purchase Plan which are currently in
progress, provided, however, that in no event will the aggregate number of
shares issuable under the 1998 Purchase Plan exceed 5,000,000 shares.

SUMMARY OF THE PROVISIONS OF THE 1998 PURCHASE PLAN

        The following summary of the 1998 Purchase Plan is qualified in its
entirety by the specific language of the 1998 Purchase Plan. A copy of the plan
is available to any stockholder upon request.

        Any employee of Bay Networks or any present or future parent or
subsidiary corporation of Bay Networks (including any director who is also an
employee) is eligible to participate in the 1998 Purchase Plan so long as the
employee is customarily employed for more than 20 hours per week and for more
than five months in a calendar year and the employee is not a participant in any
other employee stock purchase plan maintained by Bay Networks or any parent or
subsidiary corporation of Bay Networks (including the 1994 Purchase Plan). No
person who owns or holds options to purchase or as a result of participation in
the 1998 Purchase Plan would own or hold options to purchase, 5% or more of the
total combined voting power or value of all classes of stock of Bay Networks is
entitled to participate in the 1998 Purchase Plan. As of January 31, 1998,
approximately 1,766 employees would be eligible to participate in the 1998
Purchase Plan.



                                       19
<PAGE>   24

        Each offering of Common Stock under the 1998 Purchase Plan is for a
period of six months (an "Offering Period"). The initial Offering Period under
the 1998 Purchase Plan will commence on May 1, 1998. Thereafter, new Offering
Periods begin on each May 1 and November 1. Shares are purchased on the last
business day of each Offering Period ("Purchase Dates"). The Board of Directors
may establish offering periods of different durations under the 1998 Purchase
Plan.

        Participation in the 1998 Purchase Plan is limited to eligible employees
who authorize payroll deductions pursuant to the 1998 Purchase Plan. Such
payroll deductions must be a least 1% but may not exceed 10% of an employee's
compensation. Currently, the maximum amount of payroll deductions for any
participant during a six-month Offering Period is $5,040. However, the Board of
Directors, in its discretion, may provide for a different limit on payroll
deductions for an Offering Period. Once an employee becomes a participant in the
1998 Purchase Plan, that employee will automatically participate in each
successive offering which begins after the end of the Offering Period in which
he or she was a participant until such time as that employee (a) withdraws from
the 1998 Purchase Plan, (b) becomes ineligible to participate in the 1998
Purchase Plan, or (c) terminates his or her employment.

        A participant will purchase shares at the end of the Offering Period.
The purchase price per share will be equal to 85% of the lesser of the fair
market value of the Common Stock on the first day of the Offering Period or on
the Purchase Date.

        Subject to certain limitations, the number of shares of Bay Networks
Common Stock a participant purchases in each Offering Period is determined by
dividing the total amount of payroll deductions withheld from the participant's
compensation during the Offering Period by the purchase price per share. Any
cash not applied to the purchase of shares will be returned to the participant
unless the amount of such cash is less than the amount necessary to purchase a
whole share of Common Stock, in which case Bay Networks may establish procedures
to apply the remaining amount to a subsequent Offering Period.

        An employee who remains eligible to participate in the 1998 Purchase
Plan may nevertheless withdraw from an offering at any time prior to the first
day of the sixth month of an Offering Period. In effect, therefore, a
participant is given an option which he or she may or may not exercise. However,
once a participant withdraws from an offering, that participant may not again
participate in the same offering, other than to make a purchase with the
deductions already contributed during the offering.

        The 1998 Purchase Plan provides that, in the event of (i) a sale or
exchange by the stockholders of more than 50% of Bay Networks' voting stock,
(ii) a merger or consolidation in which Bay Networks is a party, (iii) the sale,
exchange or transfer of all or substantially all of the assets of Bay Networks,
or (iv) a liquidation or dissolution of Bay Networks wherein, upon any such
event, the stockholders of Bay Networks immediately before such event do not
retain direct or indirect beneficial ownership of at least 50% of the total
combined voting power of the voting stock of Bay Networks, its successor, or the
corporation to which the assets of Bay Networks were transferred (a "Change in
Control"), the acquiring or successor corporation may assume Bay Networks'
rights and obligations under the 1998 Purchase Plan or substitute substantially
equivalent purchase rights for such corporation's stock. If the acquiring or
successor corporation elects not to assume or substitute for the outstanding
purchase rights under the 1998 Purchase Plan, the Board of Directors may adjust
the last day of the Offering Period then in progress to a date on or before the
date of the Change in Control. Any purchase rights granted under the 1998
Purchase Plan that are not assumed, substituted for, or exercised prior to the
Change in Control will terminate.

        The Board of Directors may at any time amend or terminate the 1998
Purchase Plan, except that the approval of Bay Networks' stockholders is
required within 12 months of the adoption of any amendment increasing the number
of shares authorized for issuance under the 1998 Purchase Plan, or changing the
definition of the corporations which may be designated by the Board as
corporations whose employees may purchase shares of Bay Networks Common Stock
under the 1998 Purchase Plan. The 1998 Purchase Plan will continue until
terminated 



                                       20
<PAGE>   25

by the Board of Directors or when all the shares reserved for issuance under the
1998 Purchase Plan have been issued, whichever occurs first.

SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

        The federal income tax consequences of participation in the 1998
Purchase Plan are the same as the federal income tax consequences described for
participation in the 1994 Purchase Plan set forth on page 18.

VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION

        The affirmative vote of a majority of the votes cast on the proposal, at
the special meeting at which a quorum representing a majority of all outstanding
shares of Common Stock of the Company is present, either in person or by proxy,
is required for approval of this proposal. Votes for and against, abstentions
and broker non-votes will each be counted as present for purposes of determining
the presence of a quorum. Abstentions will have the same effect as a negative
vote on this proposal. Broker non-votes will have no effect on the outcome of
this vote.

        The Board believes that the adoption of the 1998 Purchase Plan is in the
best interests of the Company and its stockholders for the reasons stated above.
THEREFORE, THE BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" APPROVAL OF THIS
PROPOSAL TO ADOPT THE 1998 PURCHASE PLAN WITH AN INITIAL SHARE RESERVE EQUAL TO
THE SUM OF (A) 500,000 SHARES, PLUS (B) THE REMAINING NUMBER OF SHARES AVAILABLE
FOR ISSUANCE UNDER THE 1994 PURCHASE PLAN THAT ARE NOT REQUIRED TO COMPLETE ALL
OFFERINGS UNDER THE 1994 PURCHASE PLAN WHICH ARE CURRENTLY IN PROGRESS, UP TO A
MAXIMUM OF 5,000,000 SHARES.

                APPROVAL OF AMENDMENT TO RESTATED CERTIFICATE OF
                    INCORPORATION TO INCREASE THE AUTHORIZED
                          COMMON STOCK OF THE COMPANY

GENERAL

        On ___________, 1998, the Board authorized an amendment to the Company's
Restated Certificate of Incorporation to increase the number of authorized
shares of Common Stock from 300,000,000 to 400,000,000. The Company's Restated
Certificate of Incorporation currently authorizes the issuance by the Company of
up to 300,000,000 shares of Common Stock and 1,000,000 shares of Preferred
Stock, $0.001 par value per share (the "Preferred Shares"). As of January 31,
1998, there were approximately 220,000,000 shares of Common Stock issued and
outstanding; approximately 58,000,000 shares of Common Stock reserved for
issuance under various stock plans of the Company and its subsidiaries; and
approximately 22,000,000 shares of Common Stock remaining available for future
issuance. No Preferred Shares are issued or outstanding. The stockholders are
now being asked to approve this proposed amendment.

        The Board believes that the proposed increase is desirable so that, as
the need may arise, the Company will have more flexibility to issue shares of
Common Stock in connection with future opportunities for expanding the business
through investments or acquisitions, possible future stock dividends or stock
splits, and for other general corporate purposes. There are no preemptive rights
with respect to the Company's Common Stock and there currently is no specific
use planned for any of the additional shares being proposed for authorization
under this proposal.

        Authorized but unissued shares of the Company's Common Stock may be
issued at such times, for such purposes and for such consideration as the Board
may determine to be appropriate without further authority from the Company's
stockholders, except as otherwise required by applicable law or New York Stock
Exchange policies. The increase in authorized Common Stock will not have any
immediate effect on the rights of existing stockholders. To the extent that the
additional authorized shares are issued in the future, they will decrease the
existing stockholders' percentage equity ownership; depending upon the price at
which they are issued, they could be either dilutive or nondilutive to the
existing stockholders.

        The increase in the authorized number of shares of Common Stock and the
subsequent issuance of such shares could have the effect of delaying or
preventing a change in control of the Company without further action by the
stockholders. Shares of authorized and unissued Common Stock could (within the
limits imposed by applicable 



                                       21
<PAGE>   26

law) be issued in one or more transactions which would make a change in control
of the Company more difficult, and therefore less likely. Any such issuance of
additional stock could have the effect of diluting the earnings per share and
book value per share of outstanding shares of Common Stock, and such additional
shares could be used to dilute the stock ownership or voting rights of a person
seeking to obtain control of the Company. The Company previously adopted certain
measures that may have the effect of helping to delay or resist an unsolicited
takeover attempt.

VOTE REQUIRED AND BOARD OF DIRECTORS' RECOMMENDATION

        The affirmative vote of a majority of the voting power of all
outstanding shares of Common Stock of the Company entitled to vote at the
special meeting, at which a quorum representing a majority of all outstanding
shares of Common Stock of the Company is present and voting, either in person or
by proxy, is required for approval of this proposal. Abstentions and broker
non-votes will each be counted as present for purposes of determining the
presence of a quorum. Abstentions and broker non-votes will each have the same
effect as a negative vote on this proposal.

        The Board of Directors believes that the proposed amendment to the
Company's Restated Certificate of Incorporation to increase the number of
authorized shares of the Company's Common Stock from 300,000,000 to 400,000,000
shares is in the best interests of the Company and the stockholders for the
reasons stated above. THEREFORE, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A
VOTE "FOR" THE PROPOSAL TO AMEND THE COMPANY'S RESTATED CERTIFICATE OF
INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF THE COMPANY'S
COMMON STOCK FROM 300,000,000 SHARES TO 400,000,000 SHARES.

                               BAY NETWORKS, INC.

                        1994 EMPLOYEE STOCK PURCHASE PLAN

               (As Amended by the Board through February 20, 1998)



        1. Purpose. The Bay Networks, Inc. 1994 Employee Stock Purchase Plan
(the "Plan") is established to provide eligible employees of Bay Networks, Inc.
("Bay Networks"), and any current or future parent or subsidiary corporations of
Bay Networks which the Board of Directors of Bay Networks (the "Board")
determines should be included in the Plan (collectively referred to as the
"Company"), with an opportunity to acquire a proprietary interest in the Company
by the purchase of common stock of Bay Networks. (Bay Networks and any parent or
subsidiary corporation designated by the Board as a participating corporation
shall be individually referred to herein as a "Participating Company." For
purposes of the Plan, a parent corporation and a subsidiary corporation shall be
as defined in sections 424(e) and 424(f) of the Internal Revenue Code of 1986,
as amended (the "Code").

        It is intended that the Plan shall qualify as an "employee stock
purchase plan" under section 423 of the Code (including any future amendments or
replacements of such section), and the Plan shall be so construed. Any term not
expressly defined in the Plan but defined for purposes of section 423 of the
Code shall have the same definition herein.

        An employee participating in the Plan (a "Participant") may withdraw
such Participant's accumulated payroll deductions (if any) therein at any time
during an Offering Period (as defined below). Accordingly, each Participant is,
in effect, granted an option pursuant to the Plan (a "Purchase Right") which may
or may not be exercised at the end of a Purchase Period and which is intended to
qualify as an option described in section 423 of the Code.

        2. Administration. The Plan shall be administered by the Board and/or by
a duly appointed committee of the Board having such powers as shall be specified
by the Board. Any subsequent references to the Board shall also mean the
committee if a committee has been appointed. The Board shall have the sole and
absolute discretion to determine from time to time what parent corporations
and/or subsidiary corporations shall be Participating Companies. All questions
of interpretation of the Plan or of any Purchase Right shall be determined by
the Board and shall be final and binding upon all persons having an interest in
the Plan and/or any Purchase Right. Subject to the provisions of the Plan, the
Board shall determine all of the relevant terms and conditions of Purchase
Rights granted pursuant to the Plan; provided, however, that all Participants
granted Purchase Rights pursuant to the Plan shall have the same rights and
privileges within the meaning of section 423(b)(5) of the Code. All expenses
incurred in connection with the administration of the Plan shall be paid by the
Company.

        3. Share Reserve. The maximum number of shares which may be issued under
the Plan shall be five million six hundred fifty thousand (5,650,000) shares of
the authorized but unissued common stock of Bay Networks (the "Shares"). In the
event that any Purchase Right 



                                       1
<PAGE>   29

for any reason expires or is canceled or terminated, the Shares allocable to the
unexercised portion of such Purchase Right may again be subjected to a Purchase
Right.

        4. Eligibility. Any employee of a Participating Company is eligible to
participate in the Plan except the following:

               (a) employees who are customarily employed by the Company for
less than twenty (20) hours a week;

               (b) employees whose customary employment is for not more than
five (5) months in any calendar year; and

               (c) employees who own or hold options to purchase or who, as a
result of participation in this Plan, would own or hold options to purchase,
stock of the Company possessing five percent (5%) or more of the total combined
voting power or value of all classes of stock of any one of the corporations
referred to as the Company within the meaning of section 423(b)(3) of the Code.

        5.     Offerings.

               (a) Offering Periods. Effective for Offerings beginning on and
after November 1, 1996, the Plan shall be implemented by offerings (individually
an "Offering") of twenty-four (24) months duration (an "Offering Period"). An
Offering shall commence on May 1 and November 1 of each year; provided, however,
that no Offerings shall commence after April 24, 1998. The Offering commencing
on May 1 shall end on April 30 of the second following year. The Offering
commencing on November 1 shall end on October 31 of the second following year.
Notwithstanding the foregoing, the Board may establish a different term for one
or more Offerings and/or different commencing and/or ending dates for such
Offerings. The first day of an Offering shall be the "Offering Date" for such
Offering.

               (b) Purchase Periods. Each Offering Period shall consist of four
(4) consecutive purchase periods of six (6) months duration (the "Purchase
Period"). The last day of each Purchase Period shall be the "Purchase Date" for
such Purchase Period. A Purchase Period commencing on May 1 shall end on the
next October 31. A Purchase Period commencing on November 1 shall end on the
next April 30. The Board may establish a different term for one or more Purchase
Periods and/or different commencing dates and/or Purchase Dates for such
Purchase Periods. In the event a Purchase Date is not a business day, the
Company shall specify the business day that will be deemed the Purchase Date.

               (c) Governmental Approval; Shareholder Approval. Notwithstanding
any other provision of the Plan to the contrary, any Purchase Right granted
pursuant to the Plan shall be subject to (i) obtaining all necessary
governmental approvals and/or qualifications of the sale and/or issuance of the
Purchase Rights and/or the Shares, and (ii) obtaining shareholder approval of
the Plan. Notwithstanding the foregoing, shareholder approval shall not be
necessary in order to grant any Purchase Right granted on the Offering Date of
the Plan's initial Offering Period; 



                                       2
<PAGE>   30

provided, however, that the exercise of any such Purchase Right shall be subject
to obtaining shareholder approval of the Plan.

        6. Participation in the Plan.

               (a) Initial Participation. An eligible employee shall become a
participant in the Plan (a "Participant") on the first Offering Date after
satisfying the eligibility requirements and delivering to the Company's payroll
office two (2) weeks prior to such Offering Date or as may be established by the
Company from time to time (the "Subscription Date") a subscription agreement
indicating the employee's election to participate in the Plan and authorizing
payroll deductions. An eligible employee who does not deliver a subscription
agreement to the Company on or before the Subscription Date shall not
participate in the Plan for that Offering or for any subsequent Offering unless
such eligible employee subsequently enrolls in the Plan by complying with the
provisions of paragraph 4 and by filing a subscription agreement with the
Company on or before the Subscription Date for such subsequent Offering. An
employee who becomes eligible to participate in the Plan after an Offering has
commenced shall not be eligible to participate in such Offering but may
participate in any subsequent Offering provided such employee is still eligible
to participate in the Plan as of the commencement of any such subsequent
Offering.

               (b) Continued Participation. Participation in the Plan shall
continue until (i) the Participant ceases to be eligible as provided in
paragraph 4, (ii) the Participant withdraws from the Plan pursuant to paragraph
11, or (iii) the Participant terminates employment or dies as provided in
paragraphs 11(e) and 11(f). If a Participant is automatically withdrawn from an
Offering at the end of the first Purchase Period of such Offering pursuant to
paragraph 11(c), then the Participant shall automatically participate in the
Offering Period commencing concurrently with or immediately after the
termination of such Purchase Period. At the end of an Offering Period, each
Participant in such terminating Offering Period shall automatically participate
in the first subsequent Offering Period according to the same elections
contained in the Participant's subscription agreement effective for the Offering
Period which has just ended, provided such Participant is still eligible to
participate in the Plan as provided in paragraph 4. However, a Participant may
file a subscription agreement with respect to such subsequent Offering Period if
the Participant desires to change any of the Participant's elections contained
in the Participant's then effective subscription agreement.

        7.     Maximum Right to Purchase Shares.

               (a) Except as set forth in subparagraph (b) below, during an
Offering Period each Participant shall have a Purchase Right consisting of the
right to purchase that number of whole Shares which may be purchased at the
applicable Offering Exercise Price (as defined in paragraph 8, below), with
amount of the Participant's accumulated payroll deductions for such Offering
Period, up to a maximum equal to that number of whole Shares arrived at by
dividing twenty thousand one hundred sixty dollars ($20,160) by eighty-five
percent (85%) of the fair market value of the Shares, as determined in
accordance with paragraph 8, below on the Offering Date.



                                       3
<PAGE>   31

               (b) Notwithstanding any other provision of the Plan, no
Participant shall be entitled to purchase Shares under the Plan at a rate which
exceeds $25,000 in fair market value, determined as of the Offering Date for
each Offering Period (or such other limit as may be imposed by the Code), for
each calendar year in which the Participant participates in the Plan.

        8. Purchase Price. The purchase price at which Shares may be acquired at
the end of a Purchase Period pursuant to the exercise of all or any portion of a
Purchase Right granted under the Plan (the "Offering Exercise Price") shall be
eighty-five percent (85%) of the lesser of (a) the fair market value of the
Shares on the Offering Date of such Offering or (b) the fair market value of the
Shares on the Purchase Date or such higher price as may be set by the Board
prior to the commencement of an Offering. The fair market value of the Shares on
the Offering Date will be the closing price quoted on the New York Stock
Exchange (the "NYSE") on the last trading day prior to the Offering Date and the
fair market value of the Shares on the Purchase Date will be the closing price
quoted on the NYSE on the Purchase Date.

        9.     Payroll Deductions and Payment of Purchase Price.

               (a) Payroll Deductions. Shares which are acquired pursuant to the
exercise of all or any portion of a Purchase Right for a given Offering Period
may be paid for only by means of payroll deductions from the Participant's
Compensation accumulated during the Offering Period. For purposes of the Plan, a
Participant's "Compensation" with respect to an Offering shall include all
amounts paid in cash and includable as "wages" subject to tax under section
3101(a) of the Code without applying the dollar limitation of section 3121(a) of
the Code. Accordingly, Compensation shall include, without limitation, salaries,
commissions, bonuses, and overtime. Compensation shall not include
reimbursements of expenses, allowances, or any amount deemed received without
the actual transfer of cash or any amounts directly or indirectly paid pursuant
to the Plan or any other stock purchase or stock option plan. Except as set
forth below, the amount of Compensation to be withheld from a Participant's
Compensation during each pay period shall be determined by the Participant's
subscription agreement.

               (b) Election to Increase or Decrease Withholding. During an
Offering Period, except as provided in subparagraph 9(b)(ii), below, a
Participant may elect to increase or decrease the amount withheld from his or
her Compensation by filing an amended subscription agreement with the Company on
or before the Change Notice Date. The "Change Notice Date" shall initially be
two (2) weeks prior to the end of the first pay period for which such election
is to be effective; however, the Company may change such Change Notice Date from
time to time.

               (c)    Limitations on Payroll Withholding.

                      (i) The amount of payroll withholding with respect to the
Plan for any Participant during any pay period shall not exceed ten percent
(10%) of the Participant's Compensation for such pay period. Amounts shall be
withheld in whole percentages only and shall be reduced by any amounts
contributed by the Participant and applied to the purchase of Company stock
pursuant to any other employee stock purchase plan qualifying under section 423
of the Code.



                                       4
<PAGE>   32

                      (ii) The maximum amount of payroll deductions for any
Purchase Period may not exceed five thousand forty dollars ($5,040).

               (d) Payroll Withholding. Payroll deductions shall commence on the
first payday following the Offering Date and shall continue to the end of the
Offering Period unless sooner altered or terminated as provided in the Plan.

               (e) Participant Accounts. Individual accounts shall be maintained
for each Participant. All payroll deductions from a Participant's Compensation
shall be credited to such account and shall be deposited with the general funds
of the Company. All payroll deductions received or held by the Company may be
used by the Company for any corporate purpose.

               (f) No Interest Paid. Except as otherwise required by applicable
law, interest shall not be paid on sums withheld from a Participant's
Compensation.

        10.    Exercise of Purchase Right.

               (a) Automatic Exercise of Purchase Right. On each Purchase Date
of an Offering Period, each Participant who has not withdrawn from the Offering
or whose participation in the Offering has not terminated on or before such last
day and each beneficiary who has elected to exercise a deceased Participant's
Purchase Right (pursuant to paragraph 11(f) below) shall automatically acquire
pursuant to the exercise of the Participant's Purchase Right the number of whole
Shares arrived at by dividing the total amount of the Participant's accumulated
payroll deductions for the Purchase Period by the Offering Exercise Price;
provided, however, in no event shall the number of Shares purchased by the
Participant or the beneficiary exceed the limitations set forth in paragraph 7.
Except as provided in paragraph 11(f) below, no Shares shall be purchased on
behalf of a Participant whose participation in the Offering or the Plan has
terminated on or before the date of such exercise.

               (b) Return of Cash Balance. Any cash balance remaining in the
Participant's account shall be refunded to the Participant as soon as practical
after the Purchase Date. In the event the cash to be returned to a Participant
pursuant to the preceding sentence is an amount less than the amount necessary
to purchase a whole Share, the Company may establish procedures whereby such
cash is maintained in the Participant's account and applied toward the purchase
of Shares in the subsequent Purchase or Offering Period.

               (c) Withholding. At the time the Purchase Right is exercised, in
whole or in part, or at the time some or all of the Shares are disposed of, the
Company shall withhold from the Participant's Compensation the amount, if any,
necessary to satisfy the foreign, federal and state tax withholding obligations
of the Company which may arise upon exercise of the Purchase Right and/or upon
disposition of Shares, unless the Participant makes other arrangements with the
Company to meet such withholding obligations.

               (d) Company Established Procedures. The Company may, from time to
time, establish (A) a minimum required withholding amount for participation in
any Offering, (B) limitations on the frequency and/or number of changes in the
amount withheld during an 



                                       5
<PAGE>   33

Offering, (C) an exchange ratio applicable to amounts withheld in a currency
other than U.S. dollars, (D) payroll withholding in excess of or less than the
amount designated by a Participant in order to adjust for delays or mistakes in
the Company's processing of subscription agreements, and/or (E) such other
limitations or procedures as deemed advisable by the Company in the Company's
sole discretion which are consistent with the Plan.

               (e) Allocation of Shares. In the event the number of Shares which
might be purchased by all Participants in the Plan exceeds the number of Shares
available in the Plan, the Company shall make a pro rata allocation of the
remaining Shares in as uniform a manner as shall be practicable and as the
Company shall determine to be equitable.

               (f) Expiration of Purchase Right. Any portion of a Participant's
Purchase Right remaining unexercised after the end of the Offering Period to
which such Purchase Right relates shall expire immediately upon the end of such
Offering Period.

        11. Withdrawal and Termination of Employment.

               (a) Voluntary Withdrawal From an Offering. A Participant may
withdraw from an Offering by signing a written notice of withdrawal on a form
provided by the Company for such purpose and delivering such notice to the
Company at any time prior to the end of an Offering Period; however, if a
Participant withdraws after the Purchase Date for the first Purchase Period of
an Offering, the withdrawal shall not affect Shares acquired by the Participant
in the prior Purchase Period. A Participant may not thereafter resume
participation in the same Offering upon withdrawal from such Offering. Unless
otherwise indicated by the Participant, withdrawal from an Offering shall not
result in a withdrawal from the Plan or any succeeding Offering therein. The
Company may, from time to time, impose a requirement that the notice of
withdrawal be on file with the Company for a reasonable period prior to the
effectiveness of the Participant's withdrawal from an Offering.

               (b) Voluntary Withdrawal from the Plan. A Participant may
withdraw from the Plan by signing a written notice of withdrawal on a form
provided by the Company for such purpose and delivering such notice to the
Company. Withdrawals made after the first Purchase Date of an Offering Period
shall not affect shares acquired by the Participant on such Purchase Date. In
the event a Participant voluntarily elects to withdraw from the Plan, the
Participant may not resume participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
satisfying the requirements of paragraphs 4 and 6. The Company may impose, from
time to time, a requirement that the notice of withdrawal be on file with the
Company for a reasonable period prior to the effectiveness of the Participant's
withdrawal from the Plan.

               (c) Automatic Withdrawal From an Offering. If the fair market
value of the Shares on a Purchase Date (other than the last Purchase Date of an
Offering) is less than the fair market value of the Shares on the Offering Date
for such Offering, then every Participant shall automatically (i) be withdrawn
from the Offering at the close of the Purchase Date and after the acquisition of
Shares for such Purchase Period, and (ii) be enrolled in the Offering commencing
concurrently with or immediately after the termination of such Purchase Period.



                                       6
<PAGE>   34

               (d) Waiver of Withdrawal Right. The Company may, from time to
time, establish a procedure pursuant to which a participant may elect (an
"Irrevocable Election"), prior to the commencement of an Offering Period or
Purchase Period, to have all payroll deductions accumulated in his or her Plan
account as of the Purchase Date applied to purchase shares under the Plan and
(i) to waive his or her right to withdraw from the Offering or the Plan pursuant
to this paragraph 11, and (ii) to waive his or her right to increase, decrease,
or cease payroll deductions from his or her compensation for such Offering
during the time such election is in effect. Such election shall be made in
writing on a form provided by the Company for such purpose and must be delivered
to the Company not later than the close of business on the day prior to the
first day of the Offering Period or the Purchase Period for which such election
is to first be effective.

               (e) Termination of Employment. Termination of a Participant's
employment with the Company for any reason, including retirement, other than
death while in the employ of the Company, shall terminate the Participant's
participation in the Plan immediately. A Participant whose participation has
been so terminated may again become eligible to participate in the Plan by again
satisfying the requirements of paragraphs 4 and 6.

               (f) Death of a Participant. Upon termination of the Participant's
employment with the Company because of death, his or her beneficiary (as defined
in paragraph 13) shall have the right to elect, by written notice given to the
Company prior to the first to occur of (A) the expiration of the period of sixty
(60) days commencing with the date of the death of the Participant, or (B) the
Purchase Date next following the date of the Participant's death, either

                      (i) to withdraw all of the payroll deductions credited to 
the Participant's account under the Plan; or

                      (ii) to exercise the Participant's Purchase Right on the
Purchase Date next following the date of the Participant's death for the
purchase of the number of whole Shares which the accumulated payroll deductions
in the Participant's account at the applicable Offering Exercise Price, and any
excess in such account will be returned to said beneficiary.

In the event that no such written notice of election shall be duly received by
the Company, the beneficiary shall automatically be deemed to have elected to
withdraw the payroll deductions credited to the Participant's account at the
date of the Participant's death.

        12. Repayment of Payroll Deductions. In the event a Participant's
interest in the Plan or any Offering therein is terminated for any reason, the
balance held in the Participant's account balance shall be returned as soon as
practical after such termination to the Participant (or, in the case of the
Participant's death, to the Participant's beneficiary) and all of the
Participant's rights under the Plan shall terminate except as otherwise provided
herein. Such account balance may not be applied to any other Offering under the
Plan. Except as otherwise required by applicable law, no interest shall be paid
on sums returned to a Participant pursuant to this paragraph 12.



                                       7
<PAGE>   35

        13.    Designation of Beneficiary.

               (a) Each Participant shall have the right to designate on forms
provided by the Company a beneficiary to receive the Shares and/or cash upon the
Participant's death as provided in paragraph 11(f).

               (b) If, upon the death of a Participant, former Participant or
beneficiary, there is no valid designation of beneficiary on file with the
Company, or if the designated beneficiary is not then living, the Company shall
designate as the Beneficiary, in order of priority:

                      (i)    the surviving spouse;

                      (ii)   surviving children, including adopted children;

                      (iii)  surviving parents; or

                      (iv)   the Participant's estate, provided that at all
times the Company shall have the right to designate as beneficiary the
Participant's estate irrespective of said order of priority.

The determination of the Company as to which persons, if any, qualify within the
aforementioned categories shall be final and conclusive upon all persons.

        14. Transfer of Control. A "Transfer of Control" shall be deemed to have
occurred in the event any of the following occurs with respect to the Control
Company. For purposes of applying this paragraph 14, the "Control Company" shall
mean the Participating Company whose stock is subject to the Purchase Right.

               (a) a merger in which the shareholders before such merger do not
retain, directly or indirectly, at least a majority of the beneficial interest
in the voting stock of the Control Company; or

               (b) the sale or exchange of all or substantially all of the
Control Company's assets (other than a sale or transfer to a subsidiary of the
Company as defined in section 424(f) of the Code).

        In the event of a Transfer of Control, the Board, in its sole
discretion, shall either (i) provide that Purchase Rights granted under the Plan
shall be fully exercisable to the extent of each Participant's account balance
for the Offering Period as of a date prior to the Transfer of Control, as the
Board so determines or (ii) arrange with the surviving, continuing, successor,
or purchasing corporation, as the case may be, that such corporation assume the
Company's rights and obligations under the Plan. All Purchase Rights shall
terminate effective as of the date of the Transfer of Control to the extent that
the Purchase Right is neither exercised as of the date of the Transfer of
Control nor assumed by the surviving, continuing, successor, or purchasing
corporation, as the case may be.



                                       8
<PAGE>   36

        15. Capital Changes. In the event of changes in the common stock of the
Company due to a stock split, reverse stock split, stock dividend, combination,
reclassification, or like change in the Company's capitalization, or in the
event of any merger, sale or other reorganization, appropriate adjustments shall
be made by the Company in the Plan's share reserve, the number of Shares subject
to a Purchase Right and in the purchase price per share. Furthermore, in the
event of any such change the Board may terminate any outstanding Offering
effective on or after the effective date of any such change; provided, however,
the date of such termination shall be deemed a Purchase Date and shall be not
sooner than thirty (30) days after giving notice of such termination to the
Participants.

        16. Rights as a Stockholder and Employee. A Participant shall have no
rights as a stockholder by virtue of the Participant's participation in the Plan
until the date of the issuance of a stock certificate(s) for the Shares being
purchased pursuant to the exercise of the Participant's Purchase Right. No
adjustment shall be made for cash dividends or distributions or other rights for
which the record date is prior to the date such stock certificate(s) are issued.
Nothing herein shall confer upon a Participant any right to continue in the
employ of the Company or interfere in any way with any right of the Company to
terminate the Participant's employment at any time.

        17. Reports. Each Participant who exercised all or part of the
Participant's Purchase Right for a Purchase Period shall receive as soon as
practical after the last day of such Purchase Period a report of such
Participant's account setting forth the total payroll deductions accumulated,
the number of Shares purchased and the remaining cash balance to be refunded or
retained in the Participant's account pursuant to paragraph 9(b), if any.

        18. Plan Term. This Plan shall continue until terminated by the Board or
until all of the Shares reserved for issuance under the Plan have been issued,
whichever shall first occur.

        19. Restriction on Issuance of Shares. The issuance of shares pursuant
to the Purchase Right shall be subject to compliance with all applicable
requirements of federal or state law with respect to such securities. The
Purchase Right may not be exercised if the issuance of shares upon such exercise
would constitute a violation of any applicable federal or state securities laws
or other law or regulations. In addition, no Purchase Right may be exercised
unless (i) a registration statement under the Securities Act of 1933, as
amended, shall at the time of exercise of the Purchase Right be in effect with
respect to the shares issuable upon exercise of the Purchase Right, or (ii) in
the opinion of legal counsel to the Company, the shares issuable upon exercise
of the Purchase Right may be issued in accordance with the terms of an
applicable exemption from the registration requirements of said Act. As a
condition to the exercise of the Purchase Right, the Company may require the
Participant to satisfy any qualifications that may be necessary or appropriate,
to evidence compliance with any applicable law or regulation and to make any
representation or warranty with respect thereto as may be requested by the
Company.

        20. Legends. The Company may at any time place legends or other
identifying symbols referencing any applicable federal and/or state securities
restrictions and any provision convenient in the administration of the Plan on
some or all of the certificates representing shares of stock issued under the
Plan. The Participant shall, at the request of the Company, promptly 



                                       9
<PAGE>   37

present to the Company any and all certificates representing shares acquired
pursuant to a Purchase Right in the possession of the Participant in order to
effectuate the provisions of this paragraph 20.

        21. Non-Transferability. During the lifetime of the Participant, the
Purchase Right shall be exercisable only by said Participant. No Purchase Right
shall be assignable or transferable by the Participant, except by will or by the
laws of descent and distribution. The Company, in its absolute discretion, may
impose such restrictions on the transferability of the shares purchasable upon
the exercise of a Purchase Right as it deems appropriate and any such
restriction shall be set forth in the respective subscription agreement and may
be referred to on the certificates evidencing such shares. The Company may
require the employee to give the Company prompt notice of any disposition of
shares of stock acquired by exercise of a Purchase Right within two years from
the date of granting such Purchase Right or one year from the date of exercise
of such Purchase Right. The Company may direct that the certificates evidencing
shares acquired by exercise of a Purchase Right refer to such requirement to
give prompt notice of disposition.

        22. Amendment or Termination of the Plan. The Board may at any time
amend or terminate the Plan, except that such termination shall not affect
Purchase Rights previously granted under the Plan, nor may any amendment make
any change in a Purchase Right previously granted under the Plan which would
adversely affect the right of any Participant (except as otherwise specifically
provided in this Plan or as may be necessary to qualify the Plan as an employee
stock purchase plan pursuant to section 423 of the Code). In addition, an
amendment to the Plan must be approved by the stockholders of the Company,
within the meaning of section 423 of the Code, within twelve (12) months of the
adoption of such amendment if such amendment would authorize the sale of more
shares than are authorized for issuance under the Plan or would change the
definition of the corporations that may be designated by the Board as a
corporation the employees of which are eligible to participate in the Plan. In
addition to the foregoing, the approval of the Company's stockholders shall be
sought for any amendment to the Plan for which the Board deems stockholder
approval necessary in order to comply with Rule 16b-3 promulgated under the
Exchange Act, and amended from time to time or any successor rule or regulation.

Purchase Plan (the "PLAN") is hereby established effective as of the date of its
approval by the stockholders of the Company (the "EFFECTIVE DATE").

               1.2    PURPOSE.  The purpose of the Plan is to advance the 
interests of Company and its stockholders by providing an incentive to attract,
retain and motivate Eligible Employees of the Participating Company Group and by
motivating such persons to contribute to the growth and profitability of the
Participating Company Group. The Plan provides such Eligible Employees with an
opportunity to acquire a proprietary interest in the Company through the
purchase of Stock. The Company intends that the Plan qualify as an "employee
stock purchase plan" under Section 423 of the Code (including any amendments or
replacements of such section), and the Plan shall be so construed.

               1.3    TERM OF PLAN.  The Plan shall continue in effect until the
earlier of its termination by the Board or the date on which all of the shares
of Stock available for issuance under the Plan have been issued.

        2.     DEFINITIONS AND CONSTRUCTION.

               2.1    DEFINITIONS.  Any term not expressly defined in the Plan 
but defined for purposes of Section 423 of the Code shall have the same
definition herein. Whenever used herein, the following terms shall have their
respective meanings set forth below:

                      (a) "BOARD" means the Board of Directors of the Company.
If one or more Committees have been appointed by the Board to administer the
Plan, "Board" also means such Committee(s).

                      (b) "CODE" means the Internal Revenue Code of 1986, as
amended, and any applicable regulations promulgated thereunder.

                      (c) "COMMITTEE" means a committee of the Board duly

time, subject to the terms of the Plan and any applicable limitations imposed by
law.

                      (d) "COMPANY" means Bay Networks, Inc., a Delaware
corporation, or any successor corporation thereto.

                      (e) "COMPENSATION" means, with respect to any Offering 
Period, all amounts paid in cash and includable as "wages" subject to tax under
Section 3101(a) of the Code 


                                       1

Accordingly, Compensation shall include, without limitation, salaries,
commissions, bonuses, and overtime. Compensation shall not include
reimbursements of expenses, allowances, or any amount deemed received without
the actual transfer of cash or any amounts directly or indirectly paid pursuant

termination of employment or upon the corporation employing the Participant

shall not be deemed to have ceased to be an Employee while such individual is on
any military leave, sick leave, or other bona fide leave of absence approved by
the Company of ninety (90) days or less. In the event an individual's leave of
absence exceeds ninety (90) days, the individual shall be deemed to have ceased
to be an Employee on the ninety-first (91st) day of such leave unless the
individual's right to reemployment with the Participating Company Group is
guaranteed either by statute or by contract. The Company shall determine in good
faith and in the exercise of its discretion whether an individual has become or
has ceased to be an Employee and the effective date of such individual's
employment or termination of employment, as the case may be. For purposes of an
individual's participation in or other rights, if any, under the Plan as of the
time of the Company's determination, all such determinations by the Company

the mean of the closing bid and asked prices if the Stock is so quoted instead)
as reported by the New York Stock Exchange (the "NYSE") or such other national
or regional securities exchange or market system constituting the primary market
for the Stock, or as reported in The Wall Street Journal or such other source as
the Company deems reliable; provided, however, that the Fair Market Value of a
share of Stock on the Offering Date of an Offering shall be the closing price
quoted on the NYSE on the last trading day prior to the Offering Date. If the
relevant date does not fall on a day on which the Stock has traded on such
securities exchange or market system, the date on which the Fair Market Value
shall be established shall be the last day on which the Stock was so traded
prior to the relevant date, or such other appropriate day as shall be determined
by the Board, in its sole discretion. If there is then no public market for the
Stock, the Fair Market Value on any relevant date shall be as determined by the
Board.

                      (i) "OFFERING" means an offering of Stock as provided in
Section 6.

                      (j) "OFFERING DATE" means, for any Offering, the first day

Parent Corporation or Subsidiary Corporation designated by the Board as a
corporation the Employees of which may, if Eligible Employees, participate in
the Plan. The Board shall have the sole and absolute discretion to determine

               2.2    CONSTRUCTION.  Captions and titles contained herein are 
for convenience only and shall not affect the meaning or interpretation of any
provision of the Plan. Except when otherwise indicated by the context, the

requires otherwise.

        3.     ADMINISTRATION.

               3.1    ADMINISTRATION BY THE BOARD.  The Plan shall be 
administered by the Board. All questions of interpretation of the Plan, of any
form of agreement or other document employed by the Company in the
administration of the Plan, or of any Purchase Right shall be determined by the
Board and shall be final and binding upon all persons having an interest in the
Plan or the Purchase Right. Subject to the provisions of the Plan, the Board
shall determine all of the relevant terms and conditions of Purchase Rights
granted pursuant to the Plan; provided, however, that all Participants granted
Purchase Rights pursuant to the Plan shall have the same rights and privileges
within the meaning of Section 423(b)(5) of the Code. All expenses incurred in
connection with the administration of the Plan shall be paid by the Company.

               3.2    AUTHORITY OF EXECUTIVE OFFICERS.  Any executive officer of
the Company shall have the authority to act on behalf of the Company with
respect to any matter, right, obligation, determination or election that is the
responsibility of or that is allocated to the Company herein, provided that the
executive officer has apparent authority with respect to such matter, right,
obligation, determination or election.

               3.3 POLICIES AND PROCEDURES ESTABLISHED BY THE COMPANY. The
Company may, from time to time, consistent with the Plan and the requirements of
Section 423 of the Code, establish, change or terminate such rules, guidelines,
policies, procedures, limitations, or adjustments as deemed advisable by the
Company, in its sole discretion, for the proper administration of the Plan,
including, without limitation, (a) a minimum or maximum payroll deduction amount
required for participation in an Offering, (b) a limitation on the frequency or
number of changes, if any, permitted in the rate of payroll deduction during an
Offering, (c) an exchange ratio applicable to amounts withheld in a currency
other than United States dollars, (d) a payroll deduction greater than or less
than the amount designated by a Participant in order to adjust for the Company's
delay or mistake in processing a Subscription Agreement or in otherwise
effecting a Participant's election under the Plan or as advisable to comply with
the requirements of Section 423 of the Code, and (e) determination of the date
and manner by which the Fair Market Value of a share of Stock is determined for
purposes of administration of the Plan.

        4.     SHARES SUBJECT TO PLAN.

               4.1 MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be equal to the sum of (a) five hundred
thousand (500,000), 



                                       4
<PAGE>   42

plus (b) the aggregate number of shares of Stock available for issuance under
the Company's 1994 Employee Stock Purchase Plan (the "1994 PLAN") that are 
not required to complete all offerings under the 1994 Plan which are in progress
as of the Effective Date and shall consist of authorized but unissued or
reacquired shares of Stock, or any combination thereof; provided, however, that
the aggregate number of shares of Stock issuable under the Plan shall not exceed
five million (5,000,000) shares. If an outstanding Purchase Right for any reason
expires or is terminated or canceled, the shares of Stock allocable to the
unexercised portion of such Purchase Right shall again be available for issuance
under the Plan.

               4.2 ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of
any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, or in the event of any merger (including a merger effected for the
purpose of changing the Company's domicile), sale of assets or other
reorganization in which the Company is a party, appropriate adjustments shall be
made in the number and class of shares subject to the Plan and each Purchase
Right and in the Purchase Price. If a majority of the shares which are of the
same class as the shares that are subject to outstanding Purchase Rights are
exchanged for, converted into, or otherwise become (whether or not pursuant to
an Ownership Change Event) shares of another corporation (the "NEW SHARES"), the
Board may unilaterally amend the outstanding Purchase Rights to provide that
such Purchase Rights are exercisable for New Shares. In the event of any such
amendment, the number of shares subject to, and the Purchase Price of, the
outstanding Purchase Rights shall be adjusted in a fair and equitable manner, as
determined by the Board, in its sole discretion. Notwithstanding the foregoing,
any fractional share resulting from an adjustment pursuant to this Section 4.2
shall be rounded down to the nearest whole number, and in no event may the
Purchase Price be decreased to an amount less than the par value, if any, of the
stock subject to the Purchase Right. The adjustments determined by the Board
pursuant to this Section 4.2 shall be final, binding and conclusive.

        5.     ELIGIBILITY.

               5.1    EMPLOYEES ELIGIBLE TO PARTICIPATE.  Each Employee of a 
Participating Company is eligible to participate in the Plan and shall be deemed
an Eligible Employee, except the following:

                      (a)    Any Employee who is customarily employed by the 
Participating Company Group for less than twenty (20) hours per week; or

                      (b)    Any Employee who is customarily employed by the 
Participating Company Group for not more than five (5) months in any calendar
year.

               5.2 EXCLUSION OF CERTAIN STOCKHOLDERS. Notwithstanding any
provision of the Plan to the contrary, no Employee shall be granted a Purchase
Right under the Plan if, immediately after such grant, such Employee would own
or hold options to purchase stock of the Company or of any Parent Corporation or
Subsidiary Corporation possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of such corporation, as
determined in accordance with Section 423(b)(3) of the Code. For purposes of
this Section 5.2, 



                                       5
<PAGE>   43

the attribution rules of Section 424(d) of the Code shall apply in determining
the stock ownership of such Employee.

        6.     OFFERINGS.

               6.1 OFFERING PERIODS. Except as otherwise set forth below, the
Plan shall be implemented by Offerings of approximately six (6) months duration
(an "OFFERING PERIOD"). The first Offering Period shall commence on May 1, 1998
and end on the last day of October 1998. Subsequent Offerings shall commence on
the first day of May and November of each year and end on the last day of the
next October and April, respectively, occurring thereafter. Notwithstanding the
foregoing, the Board may establish a different duration for one or more future
Offering Periods or different commencing or ending dates for such Offering
Periods; provided, however, that no Offering Period may have a duration
exceeding twenty-seven (27) months; provided, however, that if the Code is
amended to provide for a different limitation on the maximum duration of an
Offering Period which is different from the limitation set forth in this
sentence, such different limitation shall be deemed incorporated herein. If the
first or last day of an Offering Period is not a day on which the national
securities exchanges are open for trading, the Company shall specify the trading
day that will be deemed the first or last day, as the case may be, of the
Offering Period.

               6.2    PURCHASE PERIODS.   If the Board so determines, in its 
discretion, each Offering Period may consist of two (2) or more consecutive
Purchase Periods having such duration as the Board shall specify, and the last
day of each such Purchase Period shall be a Purchase Date. If the first or last
day of a Purchase Period is not a day on which the national securities exchanges
are open for trading, the Company shall specify the trading day that will be
deemed the first or last day, as the case may be, of the Purchase Period.

        7. PARTICIPATION IN THE PLAN.

               7.1 INITIAL PARTICIPATION. An Eligible Employee may become a
Participant in an Offering Period by delivering a properly completed
Subscription Agreement to the office designated by the Company not later than
the close of business for such office on the Subscription Date established by
the Company for such Offering Period. An Eligible Employee who does not deliver
a properly completed Subscription Agreement to the Company's designated office
on or before the Subscription Date for an Offering Period shall not participate
in the Plan for that Offering Period or for any subsequent Offering Period
unless such Eligible Employee subsequently delivers a properly completed
Subscription Agreement to the appropriate office of the Company on or before the
Subscription Date for such subsequent Offering Period. An Employee who becomes
an Eligible Employee after the Offering Date of an Offering Period shall not be
eligible to participate in such Offering Period but may participate in any
subsequent Offering Period provided such Employee is still an Eligible Employee
as of the Offering Date of such subsequent Offering Period.

               7.2 CONTINUED PARTICIPATION. A Participant shall automatically
participate in the next Offering Period commencing immediately after the
Purchase Date of each Offering Period in which the Participant participates
provided that such Participant remains an Eligible 



                                       6
<PAGE>   44

Employee on the Offering Date of the new Offering Period and has not either (a)
withdrawn from the Plan pursuant to Section 12.1 or (b) terminated employment as
provided in Section 13. A Participant who may automatically participate in a
subsequent Offering Period, as provided in this Section, is not required to
deliver any additional Subscription Agreement for the subsequent Offering Period
in order to continue participation in the Plan. However, a Participant may
deliver a new Subscription Agreement for a subsequent Offering Period in
accordance with the procedures set forth in Section 7.1 if the Participant
desires to change any of the elections contained in the Participant's then
effective Subscription Agreement. Eligible Employees may not participate
simultaneously in more than one Offering.

        8.     RIGHT TO PURCHASE SHARES.

               8.1    GRANT OF PURCHASE RIGHT.  Except as set forth below, 
unless otherwise specified by the Board pursuant to Section 8.3, on the Offering
Date of each Offering Period, each Participant in such Offering Period shall be
granted automatically a Purchase Right consisting of an option to purchase that
number of whole shares of Stock determined by dividing the "Payroll Deduction
Limit" (as defined below) by eighty-five percent (85%) of the Fair Market Value
of a share of Stock on such Offering Date. No Purchase Right shall be granted on
an Offering Date to any person who is not, on such Offering Date, an Eligible
Employee.

               8.2 CALENDAR YEAR PURCHASE LIMITATION. Notwithstanding any
provision of the Plan to the contrary, no Participant shall be granted a
Purchase Right which permits his or her right to purchase shares of Stock under
the Plan to accrue at a rate which, when aggregated with such Participant's
rights to purchase shares under all other employee stock purchase plans of a
Participating Company intended to meet the requirements of Section 423 of the
Code, exceeds Twenty-Five Thousand Dollars ($25,000) in Fair Market Value (or
such other limit, if any, as may be imposed by the Code) for each calendar year
in which such Purchase Right is outstanding at any time. For purposes of the
preceding sentence, the Fair Market Value of shares purchased during a given
Offering Period shall be determined as of the Offering Date for such Offering
Period. The limitation described in this Section 8.2 shall be applied in
conformance with applicable regulations under Section 423(b)(8) of the Code.

               8.3 AMENDMENT TO PURCHASE RIGHT PROVISIONS. The Board, in its
discretion, may grant, for any future Offering Period, a Purchase Right which
provides for a different amount of shares of Stock than the amount described in
Section 8.1, including, without limitation, by amending the Payroll Deduction
Limit set forth below. In the event that the Board establishes an Offering
Period of any duration other than six (6) months, the Purchase Right described
in Section 8.1 shall be appropriately adjusted to reflect the length of such
Offering Period, unless otherwise specified by the Board. In addition, if the
Code is amended to provide for a different limitation on shares purchasable
under Section 423(b)(8) of the Code different than the limitation described in
Section 8.2, such different limitation shall be deemed incorporated herein to
the extent required or permitted by such amendment to the Code.



                                       7
<PAGE>   45

        9.     PURCHASE PRICE.

               The Purchase Price at which each share of Stock may be acquired
in an Offering Period upon the exercise of all or any portion of a Purchase
Right shall be established by the Board; provided, however, that the Purchase
Price shall not be less than eighty-five percent (85%) of the lesser of (a) the
Fair Market Value of a share of Stock on the Offering Date of the Offering
Period or (b) the Fair Market Value of a share of Stock on the Purchase Date.
Unless otherwise provided by the Board prior to the commencement of an Offering
Period, the Purchase Price for that Offering Period shall be eighty-five percent
(85%) of the lesser of (a) the Fair Market Value of a share of Stock on the
Offering Date of the Offering Period, or (b) the Fair Market Value of a share of
Stock on the Purchase Date.

        10. ACCUMULATION OF PURCHASE PRICE THROUGH PAYROLL DEDUCTION.

               Shares of Stock acquired pursuant to the exercise of all or any
portion of a Purchase Right may be paid for only by means of payroll deductions
from the Participant's Compensation accumulated during the Offering Period for
which such Purchase Right was granted, subject to the following:

               10.1 AMOUNT OF PAYROLL DEDUCTIONS. Except as otherwise provided
herein, the amount to be deducted under the Plan from a Participant's
Compensation on each payday during an Offering Period shall be determined by the
Participant's Subscription Agreement. The Subscription Agreement shall set forth
the percentage of the Participant's Compensation to be deducted on each payday
during an Offering Period in whole percentages of not less than one percent (1%)
(except as a result of an election pursuant to Section 10.3 to stop payroll
deductions made effective following the first payday during an Offering) or more
than ten percent (10%). The maximum amount of payroll deductions for any
six-month Offering Period shall be Five Thousand Forty Dollars ($5,040), which
amount shall be appropriately adjusted in the event that the Board establishes
an Offering Period of other than six (6) months (the "PAYROLL DEDUCTION LIMIT").
Notwithstanding the foregoing, the Board may change the Payroll Deduction Limit
effective as of any future Offering Date.

               10.2   COMMENCEMENT OF PAYROLL DEDUCTIONS.  Payroll deductions 
shall commence on the first payday following the Offering Date and shall
continue to the end of the Offering Period unless sooner altered or terminated
as provided herein.

               10.3   ELECTION TO CHANGE OR STOP PAYROLL DEDUCTIONS.  During an
Offering Period, a Participant may elect to increase or decrease the rate of
deductions from his or her Compensation once only during an Offering Period. 
However, a Participant may elect to decrease the rate of his or her payroll
deductions to zero percent (0%) and such Participant shall nevertheless remain a
Participant in the current Offering Period unless such Participant withdraws
from the Plan as provided in Section 12.1.

               10.4 ADMINISTRATIVE SUSPENSION OF PAYROLL DEDUCTIONS. The Company
may, in its sole discretion, suspend a Participant's payroll deductions under
the Plan as the Company deems advisable to avoid accumulating payroll deductions
in excess of the amount that could



                                       8
<PAGE>   46

reasonably be anticipated to purchase the maximum number of shares of Stock
permitted during a calendar year under the limit set forth in Section 8.2.
Payroll deductions shall be resumed at the rate specified in the Participant's
then effective Subscription Agreement at the beginning of the next Purchase
Period the Purchase Date of which falls in the following calendar year.

               10.5   PARTICIPANT ACCOUNTS.  Individual bookkeeping accounts 
shall be maintained for each Participant. All payroll deductions from a
Participant's Compensation shall be credited to such Participant's Plan account
and shall be deposited with the general funds of the Company. All payroll
deductions received or held by the Company may be used by the Company for any
corporate purpose.

               10.6   NO INTEREST PAID.  Interest shall not be paid on sums 
deducted from a Participant's Compensation pursuant to the Plan.

        11.    PURCHASE OF SHARES.

               11.1 EXERCISE OF PURCHASE RIGHT. On each Purchase Date of an
Offering Period, each Participant who has not withdrawn from the Plan and whose
participation in the Offering has not terminated before such Purchase Date shall
automatically acquire pursuant to the exercise of the Participant's Purchase
Right the number of whole shares of Stock determined by dividing (a) the total
amount of the Participant's payroll deductions accumulated in the Participant's
Plan account during the Offering Period and not previously applied toward the
purchase of Stock by (b) the Purchase Price. However, in no event shall the
number of shares purchased by the Participant during an Offering Period exceed
the number of shares subject to the Participant's Purchase Right. No shares of
Stock shall be purchased on a Purchase Date on behalf of a Participant whose
participation in the Offering or the Plan has terminated before such Purchase
Date.

               11.2   PRO RATA ALLOCATION OF SHARES.  In the event that the 
number of shares of Stock which might be purchased by all Participants in the
Plan on a Purchase Date exceeds the number of shares of Stock available in the
Plan as provided in Section 4.1, the Company shall make a pro rata allocation of
the remaining shares in as uniform a manner as shall be practicable and as the
Company shall determine to be equitable. Any fractional share resulting from
such pro rata allocation to any Participant shall be disregarded.

               11.3 DELIVERY OF CERTIFICATES. As soon as practicable after each
Purchase Date, the Company shall arrange the delivery to each Participant, as
appropriate, of a certificate representing the shares acquired by the
Participant on such Purchase Date; provided that the Company may deliver such
shares to a broker that holds such shares in street name for the benefit of the
Participant. Shares to be delivered to a Participant under the Plan shall be
registered in the name of the Participant, or, if requested by the Participant,
in the name of the Participant and his or her spouse, or, if applicable, in the
names of the heirs of the Participant.

               11.4   RETURN OF CASH BALANCE.  Any cash balance remaining in a 
Participant's Plan account following any Purchase Date shall be refunded to the
Participant as soon as practicable after such Purchase Date. However, if the
cash to be returned to a Participant 



                                       9
<PAGE>   47

pursuant to the preceding sentence is an amount less than the amount that would
have been necessary to purchase an additional whole share of Stock on such
Purchase Date, the Company may retain such amount in the Participant's Plan
account to be applied toward the purchase of shares of Stock in the subsequent
Purchase Period or Offering Period, as the case may be.

               11.5 TAX WITHHOLDING. At the time a Participant's Purchase Right
is exercised, in whole or in part, or at the time a Participant disposes of some
or all of the shares of Stock he or she acquires under the Plan, the Participant
shall make adequate provision for the foreign, federal, state and local tax
withholding obligations of the Participating Company Group, if any, which arise
upon exercise of the Purchase Right or upon such disposition of shares,
respectively. The Participating Company Group may, but shall not be obligated
to, withhold from the Participant's compensation the amount necessary to meet
such withholding obligations.

               11.6   EXPIRATION OF PURCHASE RIGHT.  Any portion of a 
Participant's Purchase Right remaining unexercised after the end of the Offering
Period to which the Purchase Right relates shall expire immediately upon the end
of the Offering Period.

               11.7 REPORTS TO PARTICIPANTS. Each Participant who has exercised
all or part of his or her Purchase Right shall receive, as soon as practicable
after the Purchase Date, a report of such Participant's Plan account setting
forth the total payroll deductions accumulated prior to such exercise, the
number of shares of Stock purchased, the Purchase Price for such shares, the
date of purchase and the cash balance, if any, remaining immediately after such
purchase that is to be refunded or retained in the Participant's Plan account
pursuant to Section 11.4. The report required by this Section may be delivered
in such form and by such means, including by electronic transmission, as the
Company may determine.

        12.    WITHDRAWAL FROM PLAN.

               12.1   VOLUNTARY WITHDRAWAL FROM THE PLAN.  A Participant may 
withdraw from the Plan by signing and delivering to the Company's designated
office a written notice of withdrawal on a form provided by the Company for such
purpose. Such withdrawal must be elected at least one (1) month prior to the end
of an Offering Period (unless otherwise specified by the Board). A Participant
who voluntarily withdraws from the Plan is prohibited from resuming
participation in the Plan in the same Offering from which he or she withdrew,
but may participate in any subsequent Offering by again satisfying the
requirements of Sections 5 and 7.1. The Company may impose, from time to time, a
requirement that the notice of withdrawal from the Plan be on file with the
Company's designated office for a reasonable period prior to the effectiveness
of the Participant's withdrawal.

               12.2 RETURN OF PAYROLL DEDUCTIONS. Upon a Participant's voluntary
withdrawal from the Plan pursuant to Section 12.1, the Participant's accumulated
payroll deductions which have not been applied toward the purchase of shares of
Stock shall be refunded to the Participant as soon as practicable after the
withdrawal, without the payment of any interest, and the Participant's interest
in the Plan shall terminate. Such accumulated payroll deductions to be refunded
in accordance with this Section may not be applied to any other Offering under
the Plan.



                                       10
<PAGE>   48

        13. TERMINATION OF EMPLOYMENT OR ELIGIBILITY.

               Upon a Participant's ceasing, prior to a Purchase Date, to be an
Employee of the Participating Company Group for any reason, including
retirement, death or disability, or the failure of a Participant to remain an
Eligible Employee, the Participant's participation in the Plan shall terminate
immediately. In such event, the payroll deductions credited to the Participant's
Plan account since the last Purchase Date shall, as soon as practicable, be
returned to the Participant or, in the case of the Participant's death, to the
Participant's legal representative, and all of the Participant's rights under
the Plan shall terminate. Interest shall not be paid on sums returned pursuant
to this Section 13. A Participant whose participation has been so terminated may
again become eligible to participate in the Plan by again satisfying the
requirements of Sections 5 and 7.1.

        14.    CHANGE IN CONTROL.

               14.1   DEFINITIONS.

                      (a)    An "OWNERSHIP CHANGE EVENT" shall be deemed to have
occurred if any of the following occurs with respect to the Company: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent (50%)
of the voting stock of the Company; (ii) a merger or consolidation in which the
Company is a party; (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or (iv) a liquidation or
dissolution of the Company.

                      (b)    A "CHANGE IN CONTROL" shall mean an Ownership 
Change Event or a series of related Ownership Change Events (collectively, the
"TRANSACTION") wherein the stockholders of the Company immediately before the
Transaction do not retain immediately after the Transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

               14.2 EFFECT OF CHANGE IN CONTROL ON PURCHASE RIGHTS. In the event
of a Change in Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "Acquiring
Corporation"), may assume the Company's rights and obligations under the Plan.
If the Acquiring Corporation elects not to assume the Company's rights and
obligations under outstanding Purchase Rights, the Purchase Date of the then
current Purchase Period shall be accelerated to a date before the date of the
Change in Control specified by the Board, but the number of shares of Stock
subject to 



                                       11
<PAGE>   49

outstanding Purchase Rights shall not be adjusted. All Purchase Rights which are
neither assumed by the Acquiring Corporation in connection with the Change in
Control nor exercised as of the date of the Change in Control shall terminate
and cease to be outstanding effective as of the date of the Change in Control.

        15.    NONTRANSFERABILITY OF PURCHASE RIGHTS.

               A Purchase Right may not be transferred in any manner otherwise
than by will or the laws of descent and distribution and shall be exercisable
during the lifetime of the Participant only by the Participant.

        16.    COMPLIANCE WITH SECURITIES LAW.

               The issuance of shares under the Plan shall be subject to
compliance with all applicable requirements of federal, state and foreign law
with respect to such securities. A Purchase Right may not be exercised if the
issuance of shares upon such exercise would constitute a violation of any
applicable federal, state or foreign securities laws or other law or regulations
or the requirements of any securities exchange or market system upon which the
Stock may then be listed. In addition, no Purchase Right may be exercised unless
(a) a registration statement under the Securities Act of 1933, as amended, shall
at the time of exercise of the Purchase Right be in effect with respect to the
shares issuable upon exercise of the Purchase Right, or (b) in the opinion of
legal counsel to the Company, the shares issuable upon exercise of the Purchase
Right may be issued in accordance with the terms of an applicable exemption from
the registration requirements of said Act. The inability of the Company to
obtain from any regulatory body having jurisdiction the authority, if any,
deemed by the Company's legal counsel to be necessary to the lawful issuance and
sale of any shares under the Plan shall relieve the Company of any liability in
respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained. As a condition to the exercise of a
Purchase Right, the Company may require the Participant to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation, and to make any representation or warranty
with respect thereto as may be requested by the Company.

        17. RIGHTS AS A STOCKHOLDER AND EMPLOYEE.

               A Participant shall have no rights as a stockholder by virtue of 
the Participant's participation in the Plan until the date of the issuance of a
certificate for the shares purchased pursuant to the exercise of the
Participant's Purchase Right (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company). No
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date such certificate is issued, except as
provided in Section 4.2. Nothing herein shall confer upon a Participant any
right to continue in the employ of the Participating Company Group or interfere
in any way with any right of the Participating Company Group to terminate the
Participant's employment at any time.

        18.    LEGENDS.

               The Company may at any time place legends or other identifying
symbols referencing any applicable federal, state or foreign securities law
restrictions or any provision convenient in the administration of the Plan on
some or all of the certificates representing shares of Stock issued under the
Plan. The Participant shall, at the request of the Company, promptly present to
the Company any and all certificates representing shares acquired pursuant to a
Purchase Right in the possession of the Participant in order to carry out the
provisions of this Section.

        19. NOTIFICATION OF SALE OF SHARES.

               The Company may require the Participant to give the Company
prompt notice of any disposition of shares acquired by exercise of a Purchase
Right within two years from the date of granting such Purchase Right or one year
from the date of exercise of such Purchase Right. The Company may require that
until such time as a Participant disposes of shares acquired upon exercise of a
Purchase Right, the Participant shall hold all such shares in the Participant's
name (or, if elected by the Participant, in the name of the Participant and his
or her spouse but not in the name of any nominee) until the lapse of the time
periods with respect to such Purchase Right referred to in the preceding
sentence. The Company may direct that the certificates evidencing shares
acquired by exercise of a Purchase Right refer to such requirement to give
prompt notice of disposition.

        20.    NOTICES.

               All notices or other communications by a Participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        21. AMENDMENT OR TERMINATION OF THE PLAN.

               The Board may at any time amend or terminate the Plan, except
that (a) such termination shall not affect Purchase Rights previously granted
under the Plan, except as permitted under the Plan, and (b) no amendment may
adversely affect a Purchase Right previously granted under the Plan (except to
the extent permitted by the Plan or as may be necessary to qualify the Plan as
an employee stock purchase plan pursuant to Section 423 of the Code or to obtain
qualification or registration of the shares of Stock under applicable federal,
state or foreign securities laws). In addition, an amendment to the Plan must be
approved by the stockholders of the Company within twelve (12) months of the
adoption of such amendment if such amendment would authorize the sale of more
shares than are authorized for issuance under the Plan or would change the
definition of the corporations that may be designated by the Board as
Participating Companies. In the event that the Board approves an amendment to
increase the number of shares authorized for issuance under the Plan (the
"ADDITIONAL SHARES"), the Board, in its sole discretion, may specify that such
Additional Shares may only be issued pursuant to Purchase Rights granted after
the date on which the stockholders of the Company approve such 



                                       13
<PAGE>   51

amendment, and such designation by the Board shall not be deemed to have
adversely affected any Purchase Right granted prior to the date on which the
stockholders approve the amendment.

        IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing Bay Networks, Inc. 1998 Employee Stock Purchase Plan was duly
adopted by the Board of Directors of the Company on ___________, 1998.

Dear Stockholder:

In preparation for Bay Networks' Special Meeting of Stockholders, we are pleased
to announce two new electronic proxy processing services for our stockholders.
In cooperation with ADP Investor Communications, all Bay Networks' stockholders
will be given the opportunity to vote their shares by telephone or through the
Internet.

1.       TO VOTE THE ENCLOSED PROXY ONLINE OR BY TELEPHONE:

         Please follow the detailed instructions provided on the yellow sheet in
         this Special Meeting mailing. You may also continue to vote shares as
         in the past by completing, signing and returning your proxy form in the
         mail.

2.       FUTURE MAILINGS:

         If you have voted the enclosed proxy online, you may register your
         e-mail address with ADP. This will eliminate future mailings of annual
         reports and proxies. Instead, you will be notified via e-mail with the
         web site to view future annual reports and vote proxy materials. (In
         addition to being able to view the proxy materials online, participants
         in this service will also have the opportunity to print all or specific
         segments of the material.)

We are looking forward to your participation in this new program for future
online voting and distribution of Bay Networks' proxy material.
