                               3Com Corporation

                              5400 Bayfront Plaza

                                PROXY STATEMENT

     The  accompanying  proxy is  solicited  by the Board of  Directors  of 3Com
Corporation,  a Delaware  corporation (the "Company" or "3Com"),  for use at the
Annual Meeting of  Stockholders  to be held on Thursday,  September 24, 1998, at
10:30 a.m. local time or any adjournment  thereof, for the purposes set forth in
the  accompanying  Notice of Annual  Meeting.  The  meeting  will be held at the
Company's principal executive offices at 5400 Bayfront Plaza,  Building 5, Santa
Clara, California. The Company's telephone number is (408) 326-5000. The date of
this Proxy  Statement is August 20,  1998,  the  approximate  date on which this
Proxy Statement and the  accompanying  form of proxy were first sent or given to
stockholders.


                              GENERAL INFORMATION

     Certain  Financial  Information.   Please  take  note  that  the  Company's
financial  statements and related  information are included with its 1998 Annual
Report to Stockholders, which is enclosed with this Proxy Statement.

     Voting Securities.  Only stockholders of record as of the close of business
on July 27, 1998 (the "Record Date") will be entitled to vote at the meeting and
any adjournment thereof. As of the Record Date, there were 358,558,817 shares of
Common Stock of the Company  issued and  outstanding.  Stockholders  may vote in
person or by proxy. Each holder of shares of Common Stock is entitled to one (1)
vote on the proposals  presented in this Proxy Statement for each share of stock
held. There is no cumulative voting in the election of directors.

     Solicitation  of Proxies.  The cost of soliciting  proxies will be borne by
the  Company.  In addition to  soliciting  stockholders  by mail and through its
regular  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,  facsimile or electronic mail, without additional  compensation.  The
Company has also retained Corporate Investor  Communications,  Inc. to assist in
obtaining proxies for the Annual Meeting from brokers,  nominees of stockholders
and institutional  investors.  The estimated fee for such services, which is not
contingent  upon  the  outcome  of the  voting,  is  $7,000  plus  out-of-pocket
expenses.

     Voting of Proxies.  All valid proxies received prior to the meeting will be
voted. All shares  represented by a proxy will be voted, and where a stockholder
specifies  by means of the 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 FOR all nominees,
FOR all other proposals  described herein and as the proxy holders may determine
in their  discretion with respect to any other matters that properly come before
the meeting.  See "Transaction of Other Business." A stockholder  giving a proxy
has the power to revoke  his or her  proxy,  at any time prior to the time it is
voted,  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.

     Quorum.  The required  quorum for the transaction of business at the Annual
Meeting is a majority  of the votes  eligible to be cast by holders of shares of
Common Stock issued and  outstanding  on the Record Date.  Shares that are voted
"FOR", "AGAINST" or "WITHHELD FROM" a matter are treated as being present at the
meeting for  purposes of  establishing  a quorum and are also  treated as shares
entitled to vote at the Annual  Meeting (the "Votes  Cast") with respect to such
matter.

     Abstentions. While  there  is no definitive statutory or case law authority
in  Delaware  as  to  the  proper treatment of abstentions, the Company believes
that abstentions should be counted for purposes


                                       1

<PAGE>

of determining  both (i) the presence or absence of a quorum for the transaction
of business  and (ii) the total  number of Votes Cast with respect to a proposal
(other than the election of directors).  In the absence of controlling precedent
to the  contrary,  the  Company  intends to treat  abstentions  in this  manner.
Accordingly,  abstentions  will  have  the same  effect  as a vote  against  the
proposal.

     Broker  Non-Votes.  Broker  non-votes  will  be  counted  for  purposes  of
determining the presence or absence of a quorum for the transaction of business,
but will not be counted  for  purposes of  determining  the number of Votes Cast
with respect to the  particular  proposal on which the broker has  expressly not
voted.  Accordingly,  broker non-votes will not affect the outcome of the voting
on a proposal  that  requires a majority of the Votes Cast (such as the approval
of a plan amendment).

<TABLE>
     Stock Ownership of Certain Beneficial Owners and Management.  The following
table sets forth certain information, as of the Record Date, with respect to the
beneficial  ownership of the  Company's  Common  Stock by (i) each  director and
director-nominee of the Company; (ii) the Chief Executive Officer and each other
executive  officer of the Company  included in the  Summary  Compensation  Table
(collectively,  the "Named Officers");  and (iii) all current executive officers
and directors of the Company as a group.

                             ELECTION OF DIRECTORS


     The number of directors  authorized by the Company's  Bylaws is to be fixed
by the Board.  The exact number is currently  fixed at 10. The Company's  Bylaws
provide that the directors  shall be divided into two classes,  with the classes
of directors serving for staggered  two-year terms.  Class II currently has five
members. A stockholder may not cast votes for more than five nominees.  The five
Class II directors to be elected at the 1998 Annual Meeting are to be elected to
hold office until the year 2000 Annual Meeting and until their  successors  have
been elected and qualified.

     The Company's  nominees for election at the Annual Meeting of  Stockholders
to Class II of the Board of Directors are Messrs. Barksdale, Benhamou, Campbell,
Cowie and Kantz. If a nominee  declines to serve or becomes  unavailable for any
reason  (although the Board of Directors  knows of no reason to anticipate  that
this will occur),  the proxies may be voted for such  substitute  nominee as the
Board of Directors may designate.


Vote Required

     If a quorum is present and voting at the Annual Meeting,  the five nominees
for Class II directors receiving the highest number of affirmative votes will be
elected as Class II directors.  Votes withheld from any director are counted for
purposes of determining  the presence or absence of a quorum,  but have no other
legal effect under Delaware law.

(1) All of the above  options  are  subject to the terms of the  Company's  1983
    Stock Option Plan (the "1983 Option Plan") and are exercisable  only as they
    vest.  The  options  granted  to each  executive  officer  vest  and  become
    exercisable in equal annual  increments over a four (4) year period provided
    the optionee continues to be employed by the Company.
(2) Aggregate option grants include options to purchase 20,850,071 shares, which

(3) All options were granted at an exercise price equal to the fair market value

    No gain to an optionee is possible without an increase in stock price, which
    will benefit all stockholders  commensurately.  A zero percent gain in stock
    price  will  result in zero  dollars  for the  optionee.  Actual  realizable
    values,  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.

Employment, Severance and Change-of-Control Arrangements

     The Company became a party to an employment  agreement with Ross W. Manire,
an employee of U.S. Robotics Corporation ("USR"), upon the merger of the Company
with USR. The employment  agreement dated January 1, 1997, as amended,  provides
for a two-year  employment period and contains provisions for automatic renewals
for  successive  one-year  terms  following the initial  term,  absent notice of
non-renewal  by either  the  Company or Mr.  Manire.  The  employment  agreement
originally  provided  for a minimum  annual base salary of $375,000  and a bonus
based on the Company's  results.  In the event of  termination  of Mr.  Manire's
employment  prior  to June 11,  1999,  the  employment  agreement  provides  for
severance  compensation  in an amount equal to the sum of Mr.  Manire's  current
salary and an amount  equal to the  average  annual  cash bonus  received by Mr.
Manire  with  respect  to the  previous  three  fiscal  years  of U.S.  Robotics
Corporation (the "Change of Control Severance"). After June 11, 1999, Mr. Manire
will be  entitled  to receive  the Change of Control  Severance  in the event of
termination  of his  employment  for any reason within one hundred  eighty (180)
days after a "Change of Control"  as defined in his  employment  agreement.  Mr.
Manire's employment  agreement also provides that he may serve as an independent
consultant of the Company, which consulting relationship would extend the period
during which certain of Mr. Manire's options would remain  exercisable but would
not extend  vesting of such options.  Mr.  Manire's  severance  compensation  is
limited to an amount that is less than the maximum  amount that Mr. Manire could
receive without it being deemed an "excess parachute payment" under Section 280G
of the Internal Revenue Code.

     In  the  Last  Fiscal Year, the Company made severance payments pursuant to
employment  agreements to the following former employees of USR: John McCartney,
Casey  G.  Cowell,  Jonathan  N.  Zakin,  Michael  S.  Seedman,  Mark Remissong,
Elizabeth S. Ryan, Henry W. Jones III and Eugene L. Ferretti.

     Options granted under the 1994 Option Plan contain  provisions  pursuant to
which  outstanding  options  must either  become  fully  vested and  immediately
exercisable  prior to a "transfer of control"  transaction or must be assumed in
the transaction,  and all unexercised  options  terminate to the extent they are
not assumed  upon such  "transfer  of control" as defined  under the 1994 Option
Plan. For purposes of the 1994 Option Plan, a transfer of control is a change in
ownership in which the  stockholders of the Company before such ownership change
do not retain,  directly or  indirectly,  at least a majority of the  beneficial
interest in the voting stock of the Company after the ownership change.

     Options granted under the 3Com Corporation  Director Stock Option Plan (the
"Director Plan") contain  provisions  pursuant to which all outstanding  options
granted  under the  Director  Plan will  become  fully  vested  and  immediately
exercisable upon a merger or acquisition of the Company where the Company is not
the survivor or upon the sale of substantially all of the assets of the Company.

Compensation of Directors

     Members  of  the  Board  who  are  not employees of the Company received an
annual  retainer during the Last Fiscal Year as follows: lead director: $30,000;
committee   members:   $25,000   each;   other  directors:  $20,000  each;  plus
reimbursement  of  travel expenses for travel by members of the Board who reside
outside of the local area.

     Outside  directors receive options to purchase Common Stock pursuant to the
Director  Plan. The Director Plan provides for the initial automatic grant of an
option  to purchase 30,000 shares of the Company's Common Stock to each director
of  the  Company  who is not an employee of the Company ("Outside Director"), or
45,000  shares  to  the  "lead"  director. In addition, each Outside Director is
automatically  granted  an  option  to  purchase  5,000  shares of the Company's
Common  Stock upon becoming a member of the Audit or Compensation Committee. The
actual  number  of  shares  to  be  subject to the options granted for Board and
committee  service is established by the administrator of the Plan. For the Last
Fiscal  Year,  the options granted to Outside Directors for service on the Board
of  Directors  were  set at 30,000 shares, or 35,000 shares including service on
Board   committees.   All   options  have  a  five-year  term,  are  immediately
exercisable  (subject  to the Company's right to repurchase any unvested shares)
and  vest  over two years as long as the option holder continues to serve on the
Board  or  the  Committee. An additional option to purchase the number of shares
of   the   Company's   Common   Stock  then  established  by  the  Committee  is
automatically  granted to each Outside Director following the vesting in full of
the  option  previously  received.  During  the  Last  Fiscal Year, options were
granted  under  the  Director Plan for the following number of shares and at the
exercise  prices  shown:  Mr.  Barksdale:  30,000 shares at a per share exercise
price  of  $51.25;  Mr.  Cowell:  45,000 shares at a per share exercise price of
$40.94;  Mr.  Cowie:  35,000 shares at a per share exercise price of $46.97; Mr.
Dorman:  22,500  shares  at  a  per  share exercise price of $55.44; Mr. Gassee:
30,000  shares at a per share exercise price of $51.75; Mr. Kantz: 35,000 shares
at  a  per  share  exercise  price  of  $32.75  and 35,000 shares at a per share
exercise  price  of  $37.25; Mr. Yovovich: 35,000 shares at a per share exercise
price  of  $46.97;  Mr.  Zuendt:  45,000 shares at a per share exercise price of
$35.13.  See  "Proposal  to Approve an Increase in the Shares Reserved Under the
Director Stock Option Plan."

     Casey G. Cowell also received the following compensation in connection with
his service as Vice  Chairman of the Company:  annual  salary of $412,885;  auto
expense of $6,875;  executive long-term  disability insurance premium of $2,078;
paid-out personal time off of $6,093; bonus of $844,615; and a severance payment
of  $9,169,965.  Mr.  Cowell  resigned as an employee of the Company in November
1997 and is currently  serving as a  consultant  to the  Company.  Mr.  Cowell's
employment  agreement also provides for reimbursement of office expenses up to a
maximum of $50,000 per year until the third anniversary of his resignation.  Mr.
Cowell is also the beneficiary of a Split Dollar Life Insurance Plan, the annual
premium of which is paid by a trust that was fully  funded by USR.  For the Last
Fiscal Year, the annual premium was $240,250.  The Company owns the trust and is
granted a security  interest in any payout on the plan for all premiums  paid by
the trust. Currently, 18 years remain on the 20-year plan.


Compensation Committee Interlocks and Insider Participation

     During the Last Fiscal Year, Messrs.  Campbell (until June 12, 1997), Kantz
and  Yovovich  (since  June 12,  1997)  served as  members  of the  Compensation
Committee of the Company's Board of Directors.


Compliance with Section 16(a) of the Securities Exchange Act of 1934

     Section 16(a) of the Securities  Exchange Act of 1934 (the "Exchange  Act")
requires  the   Company's   executive   officers,   directors  and  persons  who
beneficially  own more than 10% of the  Company's  Common  Stock to file initial
reports of ownership and reports of changes in ownership with the Securities and
Exchange  Commission  ("SEC").  Such persons are required by SEC  regulations to
furnish  the  Company  with  copies of all  Section  16(a)  forms  filed by such
persons.

     Based solely on the Company's review of such forms furnished to the Company
and written representations from certain reporting persons, the Company believes
that all filing  requirements  applicable to the Company's  executive  officers,
directors  and more than 10%  Stockholders  were  complied  with during the Last
Fiscal Year with the following  exceptions:  one report on Form 3 was filed late
for Edgar Masri, an executive officer of the Company.

                  REPORT OF THE COMPENSATION COMMITTEE OF THE
                 BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION


Summary of Compensation Policies for Executive Officers

     The goals of the  Company's  compensation  program  are to:  (i) enable the
Company to attract, retain and motivate highly-qualified employees and executive
officers who  contribute  to the  long-term  success of the Company;  (ii) align
compensation  with  business   objectives  and  performance;   and  (iii)  align
incentives  for  executive  officers  with  the  interests  of  stockholders  in
maximizing   stockholder   value.  The  Company   emphasizes   performance-based
compensation  that is competitive  with the  marketplace,  and the importance of
clearly communicating  performance objectives.  The Company annually reviews its
compensation  practices by comparing them to surveys of relevant competitors and
sets  objective  compensation  parameters  based  on this  review.  Compensation
policies  also  reflect  the  competition  for  executive  talent and the unique
challenges and  opportunities  facing the Company in the global data  networking
market.

     The Company's  compensation  program for all employees  includes both cash-
and equity-based elements. Because it is directly linked to the interests of our
stockholders,  equity-based  compensation  is  emphasized  in the  design of the
Company's  compensation  programs.  Consistent with competitive  practices,  the
Company  also  utilizes  a cash bonus plan  based on  achievement  of  financial
performance objectives although, as more fully discussed below,  executives will
not  participate  in such cash bonus plan during  fiscal  year 1999  because the
executive bonus plan will be entirely equity-based.

     In the Last Fiscal Year, the Company failed to meet its annual  performance
objectives and its quarterly  targets in all but the first quarter of the fiscal
year.  Thus,  cash bonuses were not earned by employees,  including  executives,
during the final three quarters of the year. Likewise, no executive bonus option
grants were  awarded for the Last Fiscal Year.  However,  in January  1998,  the
Company repriced certain stock options held by non-executive employees,  subject
to restriction on exercising repriced options during the ensuing nine months. At
the time of this action,  voluntary turnover had increased  substantially  above
the  historical   average,   exacerbated  by  the  fact  that  the  majority  of
non-executive  employee  options had exercise prices well above the then current
market  price.  The Company had not repriced any stock  options in the preceding
5-year  period and deemed it necessary and in the best interest of the Company's
stockholders to take such extraordinary  action in the Last Fiscal Year in order
to  retain  and  motivate  key  employees,   engineers,   sales  people,  Global
Information  Systems  specialists  and  management.  No  options  held by senior
executives or directors were repriced.


Cash Compensation

     Salary.  The Company sets a base salary range for each  executive  officer,
including  the  Chief  Executive  Officer,  by  reviewing  the base  salary  for
comparable positions of a broad peer group,  including companies similar in size
and business which compete with the Company in the  recruitment and retention of
senior personnel. Base pay is targeted at the midpoint of market on the basis of
external  salary data from  independent  surveys.  Individual  salaries for each
executive officer are set relative to this target based on sustained  individual
performance  and   contribution  to  the  Company's   results.   Although  total
compensation,  including  equity-based  compensation,  is targeted at the market
average for comparable positions,  for fiscal year 1999, the Company has adopted
a  risk-based  compensation  structure  for  executives  in which the cash bonus
opportunity was eliminated and performance-based target stock option levels were
increased correspondingly. This structure is discussed in further detail below.

     Cash  Bonus.  Non-executive  employees  of  the  Company  are  eligible  to
participate  in the  Company's  cash  bonus  plan,  known as  3Bonus.  This plan
provides cash awards for meeting quarterly revenue and earnings per share goals,
based on a matrix in which 100% of target may be achieved  only if the Company's
results are consistent with its targeted long-term financial model.  Targets for
quarterly cash bonus awards range from five to thirty-five percent of employees'
eligible  base  salary  for such  period.  Awards may range from zero to 150% of
target and can be earned quarterly,  based on achievement of stated  performance
objectives.  The Company will not provide any cash bonus program for  executives
in fiscal year 1999.


                                       11

<PAGE>

Equity-Based Compensation

     To enhance retention,  options granted to executive officers are subject to
vesting  restrictions  that  lapse in  annual  increments.  Performance  options
granted by the Company after the end of a fiscal period at the then-current fair
market  value become  valuable and  exercisable  only if the  executive  officer
continues to serve the Company and the price of the Company's stock subsequently
increases.  Initial or "new-hire" options are granted to executive officers when
they  first  join  the  Company.  Thereafter,  options  may be  granted  to each
executive officer as an equity bonus if specified performance goals are achieved
("performance  options").  The relevant performance goals and range of potential
option grants are established by the Board of Directors and  communicated at the
beginning of each fiscal year. The amount of actual options granted depends upon
the percentage of the Company's and the officer's  performance  objectives  that
are achieved.  Performance  options  focus the efforts of executive  officers on
achieving the critical Company  operational  targets for revenue performance and
earnings  per  share  that  will  enhance  the  Company's   credibility  in  the
marketplace.

     In order to minimize  its  vulnerability  to losing key  executives  during
fiscal year 1999,  the  Company  will  change the timing of  performance  option
grants.  Half of the  equity  for this  bonus  program  will be  awarded  at the
beginning  of the  first  quarter,  based  on an  objective  assessment  of past
individual  performance.  The  remainder  of the  target  bonus  in the  form of
performance  grants may be earned and will be awarded on the basis of  achieving
revenue and earnings per share targets for each quarter during fiscal year 1999.

     In  designing  executive  compensation  for fiscal  year 1999,  the Company
retained  an  outside  consultant  to  perform  a  comprehensive  assessment  of
compensation  for its Chief Executive  Officer and to other executive  officers.
The services rendered by the consultant to the Compensation  Committee  included
surveying  competitors'  practices,   assessing  the  mix  of  pay  relative  to
competitive practices,  evaluating the linkage between pay and performance,  and
recommending compensation strategies.

     The Committee has  considered  the potential  impact of Section 162(m) (the
"Section")  of the  Internal  Revenue  Code  adopted  under the Federal  Revenue
Reconciliation  Act of 1993.  The  Section  disallows  a tax  deduction  for any
publicly-held  corporation for individual  compensation  exceeding $1 million in
any  taxable  year  for  any  of  the  named  executive  officers,   other  than
compensation that is performance-based.  Since the targeted cash compensation of
the majority of the named executive  officers is below the $1 million  threshold
and the Company  believes  that any options  granted  under the 1983 Option Plan
will  meet the  requirement  of being  performance-based  under  the  transition
provisions  provided  in  the  regulations  under  the  Section,  the  Committee
concluded  that the  Section  should not  materially  reduce the tax  deductions
available  to the  Company  and that no  changes to the  Company's  compensation
program were needed in this regard.


CEO Compensation

     The Chief Executive  Officer's  salary and performance  stock option grants
follow the policies  set forth  above.  Mr.  Benhamou's  base annual  salary for
fiscal year 1998 of $742,500 reflects his position, duties and responsibilities.
The CEO's  salary  increase  in fiscal  year 1998 was based on the  Compensation
Committee's  evaluation of his  performance  and the Company's  performance.  In
addition,  Mr. Benhamou received a cash bonus of $75,008 during fiscal year 1998
pursuant to the bonus plan in effect for all employees. The Company did not meet
its objectives set forth in the fiscal year 1998 plan, and Mr.  Benhamou did not
receive a performance option grant for such period.

        PROPOSAL TO APPROVE AN INCREASE IN THE SHARE RESERVE UNDER THE
                       1984 EMPLOYEE STOCK PURCHASE PLAN

     As a result of a recent change in the financial  accounting rules regarding
employee stock purchase plans,  the Board of Directors has determined that it is
in the best interests of the Company and its stockholders to increase the shares
reserved under the 1984 Employee Stock Purchase Plan ("Purchase  Plan"). On July
22, 1998, the Board of Directors approved (subject to stockholder  approval) the
amendment to the Purchase  Plan and reserved two million  (2,000,000)  shares of
Common Stock for issuance thereunder for a total of 22,000,000 shares.

     At the Annual  Meeting,  the  stockholders  are being  asked to approve the
amendment to the  Purchase  Plan.  No options have been granted  pursuant to the
Purchase  Plan  to  purchase  the  shares  added  to the  Purchase  Plan by this
amendment.


Vote Required

     The  affirmative  vote of a  majority  of the Votes  Cast is  required  for
approval of this proposal.  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE
"FOR" APPROVAL OF THE AMENDMENT TO THE 1984 EMPLOYEE STOCK PURCHASE PLAN.


Summary of Provisions of the Purchase Plan

     The  summary of the  Purchase  Plan  included  in this Proxy  Statement  is
qualified  in its entirety by the specific  language of the  Purchase  Plan,  as
amended.  Copies of the  Purchase  Plan are  available to any  stockholder  upon
request addressed to Mark D. Michael, Senior Vice President, General Counsel and
Secretary, 3Com Corporation, 5400 Bayfront Plaza, Santa Clara, CA 95052-8145.

     Administration and Share Reserve.  The Purchase Plan is administered by the
Board of Directors or a committee of the Board. Since its inception,  a total of
20,000,000  shares of the Company's  Common Stock (without  giving effect to the
proposed  amendment) have been reserved for issuance under the Purchase Plan and
15,985,152  shares have been issued under the plan as of the Record  Date.  This
proposal seeks  stockholder  approval to increase the number of shares  reserved
for issuance under the Purchase Plan by two million (2,000,000) shares.

     Eligibility.  Any  employee  of  the  Company  or  any  present  or  future
subsidiary  corporation of the Company (including any officer or director who is
also an employee) is eligible to participate in the Purchase Plan as long as the
employee is  customarily  employed for at least 20 hours per week. No person who
owns or holds options to purchase,  or who as a result of  participation  in the
Purchase Plan would own or hold options to purchase, 5% or more of the Company's
Common  Stock is entitled to  participate  in the Purchase  Plan.  As of May 31,
1998,  approximately 6,500 employees were participating in the Purchase Plan out
of the  approximately  13,000 employees  eligible to participate in the Purchase
Plan.

     Participation   In  An  Offering.   Offerings   under  the  Purchase   Plan
("Offering(s)") are six months long and commence on the first day of October and
the first  day of April of each  year.  Participation  in the  Purchase  Plan is
limited to eligible employees who authorize payroll  deductions  pursuant to the
Purchase  Plan. At present,  such payroll  deductions may not exceed 10% of base
pay. Once an employee  becomes a participant  in the Purchase Plan, the employee
will  automatically  participate in each successive  Offering until such time as
the employee  withdraws  from the  Purchase  Plan or the  employee's  employment
terminates.

     Purchase  Price.  The  purchase  price per share at which the shares of the
Company's  Common Stock are sold under the Purchase Plan generally will be equal
to 85% of the lesser of the fair  market  value of the  Common  Stock on (a) the
first day of the applicable six-month offering period or (b) the last day of the
six-month offering period.

     Shares  Purchased.  The number of shares of the  Company's  Common  Stock a
participant  purchases  in each  Offering is  determined  by dividing  the total
amount of payroll deductions withheld from the participant's compensation by the
purchase price per share.  Participants may not purchase shares of the Company's
Common Stock having a fair market value exceeding  $25,000 in any calendar year.
For this


                                       14

<PAGE>

purpose,  the fair market value of the  Company's  Common  Stock  purchased in a
given Offering is determined as of the first day of that Offering.  Furthermore,
a  participant  may not purchase  more than 1,000  shares in a single  Offering,
although this limit may be adjusted by the Board of Directors  from time to time
to reflect  fluctuations in the fair market value of the Company's  Common Stock
to the extent  permitted  by law. Any cash not applied to the purchase of shares
is  returned to the  participant  (except  for cash  insufficient  to purchase a
single share of the Company's Common Stock) at the end of the Offering.

     Withdrawal. A  participant  may  withdraw  from  an  Offering  at  any time
without affecting his or her eligibility to participate in future Offerings.

     Adjustment  Upon Change in  Capitalization.  In the event that the stock of
the Company is changed by reason of any stock split,  reverse stock split, stock
dividend, combination, reclassification or other change in the capital structure
of the  Company,  or in  the  event  of  any  merger,  sale  or  reorganization,
appropriate  adjustments shall be made in the number and shares of stock subject
to the  Purchase  Plan,  the  number  of  shares  of stock  subject  to  options
outstanding  under  the  Purchase  Plan,  and the  exercise  price  of any  such
outstanding options.

     Amendment or  Termination.  The Board of Directors may at any time amend or
terminate the Purchase Plan, except that approval of the Company's  stockholders
within 12 months of the  adoption of such  amendment is required to increase the
number of shares  authorized  for issuance  under the Purchase Plan or to change
the  designation  of  corporations  whose  employees may purchase  shares of the
Company's Common Stock under the Purchase Plan. The Purchase Plan will terminate
when all of the shares  reserved for issuance  under the Purchase Plan have been
issued or when earlier terminated by the Board of Directors.


Federal Income Tax Information for Purchase Plan

     The  Purchase  Plan,  and the  right  of  participants  to  make  purchases
thereunder,  is intended to qualify under the provisions of Sections 421 and 423
of the Internal  Revenue Code (the "Code").  Under these  provisions,  no income
will be taxable to a participant  until the shares  purchased under the Purchase
Plan are sold or otherwise  disposed of. Upon sale or other  disposition  of the
shares,  the participant  will generally be subject to tax and the amount of the
tax will  depend upon the holding  period.  If the shares are sold or  otherwise
disposed of more than two (2) years from the first day of the  Offering  Period,
then the  participant  will recognize  ordinary income measured as the lesser of
(i) the excess of the fair  market  value of the shares at the time of such sale
or  disposition  over the  purchase  price or (ii) an amount equal to 15% of the
fair market value of the shares as of the first day of the Offering Period.  Any
additional  gain will be treated as long-term  capital  gain.  If the shares are
sold or otherwise  disposed of before the expiration of this holding period, the
participant will recognize  ordinary income generally  measured as the excess of
the fair market  value of the shares on the date the shares are  purchased  over
the purchase price. Any additional gain or loss on such sale or disposition will
be  long-term  or  short-term  capital  gain or loss,  depending  on the holding
period.  Net capital  gains on shares held between 12 and 18 months may be taxed
at a maximum  federal  rate of 28%,  while net capital  gains on shares held for
more  than 18  months  may be taxed at a maximum  federal  rate of 20%.  Capital
losses are allowed in full against  capital gains and up to $3,000 against other
income. Unless limited by Section 162(m) of the Code, the Company is entitled to
a deduction to the extent ordinary  income is recognized by participants  upon a
sale or disposition  of shares prior to the expiration of the holding  period(s)
described above.

     The  foregoing is only a summary of the effect of federal  income  taxation
upon the participant and the Company with respect to the shares  purchased under
the Purchase Plan. Reference should be made to the applicable  provisions of the
Code.  In  addition,  the summary  does not discuss  the tax  consequences  of a
participant's  death or the income  tax laws of any state or foreign  country in
which the participant may reside.

Participation in the Purchase Plan

     Participation  in the Purchase  Plan is voluntary  and is dependent on each
eligible  employee's  election to participate and his or her determination as to
the  level of  payroll  deductions.  Accordingly,  future  purchases  under  the
Purchase Plan are not determinable.  Non-employee  directors are not eligible to
participate in the Purchase Plan. No purchases have been made under the Purchase
Plan since its amendment by the Board.  However,  purchases  were made under the
Purchase Plan prior to such  amendment.  The following  table sets forth certain
information  regarding  shares purchased under the Purchase Plan during the Last
Fiscal Year and the payroll deductions accumulated at the end of the Last Fiscal
Year in accounts under the Purchase Plan for each of the Named Officers, for all
current  executive  officers  as  a  group  and  for  all  other  employees  who
participated in the Purchase Plan as a group:

       PROPOSAL TO APPROVE AN INCREASE IN THE SHARES RESERVED UNDER THE
                          DIRECTOR STOCK OPTION PLAN

     The Board of Directors has  determined  that it is in the best interests of
the  Company and its  stockholders  to increase  the shares  reserved  under the
Director  Stock Option Plan  ("Director  Plan").  On July 22, 1998, the Board of
Directors  approved  (subject to  stockholder  approval)  the  amendment  to the
Director  Plan and  reserved an  additional  one million  (1,000,000)  shares of
Common Stock for issuance thereunder, for a total of 3,000,000 shares.

     At the Annual  Meeting,  the  stockholders  are being  asked to approve the
amendment to the  Director  Plan.  No options have been granted  pursuant to the
Director  Plan  to  purchase  the  shares  added  to the  Director  Plan  by the
amendment.

Summary of Provisions of the Director Plan

     The  summary of the  Director  Plan  included  in this Proxy  Statement  is
qualified  in its entirety by the specific  language of the  Director  Plan,  as
amended.  Copies of the  Director  Plan are  available to any  stockholder  upon
request addressed to Mark D. Michael, Senior Vice President, General Counsel and
Secretary, 3Com Corporation, 5400 Bayfront Plaza, Santa Clara, CA 95052-8145.

     Administration  and Share Reserve.  The Director Plan is to be administered
by the full Board of  Directors  or by a committee  of the Board  consisting  of
those  directors  who are  employees of the Company (the  "Administrator").  All
options  granted  under the  Director  Plan are  "nonqualified  stock  options."
Eligible  participants are limited to the directors who are not employees of the
Company ("Outside Directors").  A total of 3,000,000 shares of Common Stock have
been  reserved for  issuance  under the Director  Plan (of which  1,000,000  are
subject to Stockholder  approval),  subject to  proportionate  adjustment in the
event of subdivisions  or combinations of the Company's  Common Stock. As of the
Record  Date,   options  to  purchase  769,000  shares  remain  outstanding  and
unexercised and options to purchase 1,064,000 shares have been exercised.

     Option Grants. Each Outside Director is automatically  granted an option to
purchase  shares  of the  Company's  Common  Stock at the  first  Board  meeting
following  the date upon  which he or she first  becomes  eligible  in an amount
established under the guidelines then in effect as adopted by the Administrator.
The  maximum  number of shares that may be subject to each such option is 60,000
shares,  except that if the eligible director is the Chairman of the Board, then
the maximum is 80,000 shares.  Each eligible member of the Audit or Compensation
Committees is automatically  granted an additional  option to purchase shares of
Common  Stock at the first  Board  meeting  occurring  on or after the date such
member first joins either  committee;  the maximum  number of shares that may be
subject to each  option for  committee  service is 24,000  shares.  The  maximum
number of shares that may be subject to options granted under the Director Plan,
the  numbers of shares to be  granted  within  those  maximum  limits  under the
Administrator's guidelines in effect from time to time, and the number of shares
subject to outstanding options (and the exercise price of such options), are all
subject  to   proportionate   adjustment  in  the  event  of  stock   dividends,
subdivisions or combinations of the Company's  Common Stock.  From time to time,
but not more than  once  every  six  months,  the  Administrator  may  establish
guidelines  to specify the number of shares to be subject to each  automatically
granted option (subject to the maximum limits set forth above), which guidelines
are intended to be in accordance with the Company's other compensation policies.
On each grant  date,  the number of shares  subject to each  option  granted for
service on the Board of Directors or the Audit or  Compensation  Committees,  as
the case may be, may not vary among  Outside  Directors,  except that an Outside
Director  who is the  Chairman of the Board or who is  designated  as the "lead"
Outside Director may be granted an option for more shares than the other Outside
Directors.   During  the  fiscal  year  ending  May  31,  1998,  the  guidelines
established  standard  option grant  amounts as 30,000  shares for service as an
outside director and 35,000 shares for board and committee service.

     Terms and  Conditions of Options.  Options  granted under the Director Plan
have a per share exercise price equal to the fair market value of a share of the
Company's Common Stock on the date of the option grant.  Options are immediately
exercisable  and vest in 24 equal  monthly  increments,  so long as the optionee
continues to serve on the Board or the committee.  No option is exercisable more
than five years from the date of grant.  Options may be  exercised by payment of
the  exercise  price  (a) in cash or  check,  (b) by  tender  of  shares  of the
Company's Common Stock having a fair market value equal to the exercise price or
(c) by delivery of a promissory note payable to the Company. During the lifetime
of the optionee,  the option may only be exercised by the optionee. In the event
of the  death  of the  optionee,  to the  extent  the  option  has not yet  been
exercised,  the optionee's  estate,  or any person who has acquired the right to
exercise  the option by bequest or  inheritance,  may exercise the option at any
time within six months  following  the date of death.  Following  the vesting in
full of an option previously  received,  an additional option to purchase shares
of the  Company's  Common  Stock  is  automatically  granted  to  each  eligible
participant in accordance with the option grant provisions described above.

     Company  Repurchase  Right. Unless  otherwise  provided  by  the Committee,
unvested  shares  of  the  Company's  Common  Stock  purchased  pursuant  to the
exercise of an option granted under the Director


                                       17

<PAGE>

Plan may be  repurchased  by the Company at the initial  purchase  price of such
unvested shares upon termination of the optionee's  service as a director of the
Company for any reason other than death.

     Amendment  or  Termination.  The  Board  generally  has the power to amend,
suspend  or  terminate  the  Director  Plan at any time and to amend  individual
options with the approval of the  affected  optionee to the extent  permitted by
governing law.  However,  the terms of the Director Plan require the approval of
the Company's  stockholders of any amendment to the Director Plan that increases
the  number  of shares  issuable  thereunder  or  expands  the class of  persons
eligible to receive options.


Summary of United States Federal Income Tax Consequences of the Director Plan

     The following  summary is intended only as a general guide as to the United
States  federal  income  tax  consequences  under  current  law with  respect to
participation  in the  Director  Plan,  and does not  attempt  to  describe  all
possible  federal  or other  tax  consequences  of such  participation.  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.
Optionees  should consult their own tax advisors prior to the disposition of any
shares of Common Stock acquired pursuant to the Director Plan.

     An optionee  will  recognize no taxable  income at the time a  nonqualified
stock option is granted under the Director  Plan.  The optionee  will  recognize
ordinary income on the determination  date (as defined below) in an amount equal
to the excess of the fair market value on the  determination  date of the shares
acquired over the option  exercise  price.  The  determination  date will be the
later of (a) the date on which the nonqualified  stock option is exercised (with
respect to the shares acquired),  (b) the date on which the shares acquired vest
or (c) the date on which  the sale of the  shares  at a profit  would no  longer
subject the optionee to suit under Section 16(b) of the Securities  Exchange Act
of 1934, as amended (the "Exchange Act")  (generally,  six months after the date
of grant). Notwithstanding the foregoing, if the determination date is after the
exercise  date,  the optionee may elect pursuant to Section 83(b) of the Code to
have the determination  date be the exercise date by filing an election with the
Internal  Revenue  Service  not later  than 30 days after the date the option is
exercised.

     In general, upon the sale or exchange of shares acquired by the exercise of
a nonqualified  stock option,  any gain or loss, based on the difference between
the amount  realized  upon such  disposition  and the fair  market  value of the
shares on the  determination  date, will be taxed as a capital gain or loss. Net
capital  gains on shares held between 12 and 18 months may be taxed at a maximum
federal  rate of 28%,  while net  capital  gains on shares held for more than 18
months may be taxed at a maximum federal rate of 20%. Capital losses are allowed
in full against  capital gains and up to $3,000 against other income.  There are
no  federal  income  tax  consequences  to  the  Company  upon  the  grant  of a
nonqualified  stock  option.  The Company  will  generally  be entitled to a tax
deduction equal to the amount of ordinary income recognized by the optionee with
respect to shares acquired upon exercise of a nonqualified stock option.


         RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     The Board has  selected  Deloitte  & Touche LLP as the  independent  public
accountants  of the Company for the fiscal year ending May 28, 1999.  Deloitte &
Touche LLP has acted in such  capacity  since its  appointment  for fiscal  year
1980.  A  representative  of Deloitte & Touche LLP will be present at the Annual
Meeting,  will be given the  opportunity  to make a  statement,  if he or she so
desires, and will be available to respond to appropriate questions.

     In the  event  ratification  by the  stockholders  of  the  appointment  of
Deloitte & Touche LLP as the Company's  independent  public  accountants  is not
obtained, the Board will reconsider such appointment.


Vote Required

     The  affirmative  vote of a  majority  of the Votes  Cast is  required  for
approval of this proposal.  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE
"FOR"  RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE COMPANY'S
INDEPENDENT PUBLIC ACCOUNTANTS FOR THE FISCAL YEAR ENDING MAY 28, 1999.

                                3Com CORPORATION

                           DIRECTOR STOCK OPTION PLAN

                   (As Amended by the Board on July 22, 1998)

         1. Purpose.  It is the purpose of this Director  Stock Option Plan (the
"Plan") to enable 3Com  CORPORATION  (the  "Company")  and its  subsidiaries  to
retain  and  provide  incentives  to  outside  directors  by  offering  them  an
opportunity to acquire a proprietary interest in the Company.

         2.  Eligibility  and  Administration.  Eligible  participants  shall be
limited to outside directors of the Company and its subsidiaries. The Plan shall
be administered by a committee of the Company's Board of Directors (the "Board")
consisting of its directors who are also employees of the Company. The Board and
such  committee are both  referred to as the Board and the committee  shall have
all the  powers of the  Board  hereunder,  including,  without  limitation,  the
authority to, from time to time,  establish  guidelines (the  "Guidelines") that
determine  the number of shares to be subject to the options  granted  under the
Plan,  subject to the per option  limits set forth in Sections 4(b) and 4(c) and
the  restriction  on  amendment  of the  Guidelines  set forth in Section 9. The
Guidelines  must (i) provide  that on each grant  date,  the number of shares of
Common Stock subject to each option  automatically  granted  pursuant to Section
4(b) or 4(c), as the case may be, shall be equal for each eligible  participant,
subject to distinctions based on the outside director's  position as Chairman of
the Board,  designation  as the "lead"  outside  director,  and service on Board
committees,  and (ii) not cause an outside director who receives an option under
the Plan to cease to be a  "disinterested  person"  for  purposes  of Rule 16b-3
under  the  Securities  Exchange  Act of 1934,  as  amended.  All  questions  of
interpretation  of the Plan or of any option shall be  determined  by the Board,
and such  determinations  shall be final and binding upon all persons  having an
interest in the Plan or such option.

         3.    Shares Subject to Plan.

               (a)  Subject to  adjustment  as  provided  in Section  3(b),  the
maximum  number of shares of the  Company's  common stock  ("Common  Stock") and
rights to acquire Common Stock that may be issued pursuant to this Plan shall be
3,000,000  shares.  Options or shares that are issued to participants  under the
Plan and  terminate  without  being  exercised  shall  revert  to the  status of
authorized but unissued options or shares under the Plan.

               (b) 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,  appropriate  adjustments shall be made
in the number and class of shares  subject to the Plan,  the  Guidelines and the
per option limits set forth in Section 4, and to 

                                       1

<PAGE>


any  outstanding  options  granted under the Plan,  and in the exercise price of
such outstanding options.

         4.    Rights Issuable Under the Plan.

                (a) During the term of the Plan, eligible  participants shall be
granted options to acquire shares of the Common Stock of the Company ("Options")
as provided in this Section 4. Each Option shall be  exercisable  immediately as
to all shares of Common Stock subject to the Option and shall vest in 24 monthly
increments.  All Options shall be subject to the terms and  conditions set forth
in the form of Nonqualified Stock Option Agreement attached hereto as Exhibit 1;
provided,  however,  that the Board may at the time of grant of any Option  make
such  modifications  to such terms and conditions as are otherwise in compliance
with the restrictions contained in the Plan.

               (b) The Board shall  grant an Option to  purchase  that number of
shares as may be  specified  in the  Guidelines  then  currently  in effect (the
"Guideline  Amount") for service on the Board,  not to exceed  60,000  shares of
Common Stock (or 80,000 shares if the  participant  is the Chairman of the Board
on the date of grant),  to each eligible  participant at the first Board meeting
following the date upon which he or she first becomes eligible.  Thereafter, the
Board shall grant an  additional  Option to purchase that number of shares equal
to the Guideline Amount for service on the Board, not to exceed 60,000 shares of
Common Stock (or 80,000 shares if the  participant  is the Chairman of the Board
on the date of grant), to an eligible participant  following the vesting in full
of the Option of that  eligible  participant  most  recently  granted under this
Section 4(b) for service on the Board.  Such  additional  grant shall be made at
the first Board  meeting  following  the  vesting in full of such most  recently
granted Option.

               (c) In addition to the Options  granted by the Board  pursuant to
Section 4(b),  the Board shall grant an Option to purchase that number of shares
equal to the Guideline Amount for service on a Standing Committee, not to exceed
24,000  shares  of Common  Stock,  to each  eligible  participant  serving  on a
Standing  Committee of the Board at the first meeting of the Board  occurring on
or after the date on which he or she begins to serve on a Standing Committee.  A
Standing  Committee  shall mean either the Audit  Committee or the  Compensation
Committee of the Board.  Thereafter,  the Board shall grant an additional Option
to purchase that number of shares equal to the Guideline Amount for service on a
Standing  Committee,  not to  exceed  24,000  shares of  Common  Stock,  to each
eligible  participant who continues to serve on a Standing  Committee  following
the vesting in full of the Option of that  eligible  participant  most  recently
granted  under this Section  4(c).  Such  additional  grant shall be made at the
first Board meeting  following the vesting in full of such most recently granted
Option.

         5.  Consideration.  The exercise  price for Options shall be payable by
(i)  delivery of cash or check,  (ii) tender of shares of Common  Stock having a
fair  market  value  equivalent  to the  purchase or  exercise  price,  or (iii)
delivery of a promissory note payable to the Company;  provided,  however,  that
the  Board  may  impose  at the  time of any  grant  

                                       2

<PAGE>

of rights  hereunder  such  restrictions  on the  exchange  of  Common  Stock or
delivery of a promissory note as the Board may deem appropriate or necessary and
that any promissory  note shall be secured by such  collateral as is required by
the attached form of Nonqualified Stock Option Agreement,  or as the Board shall
otherwise determine at the time of grant.

         6.  Exercise  Price.  The exercise  price  payable upon exercise of any
Option  shall be equal to the fair  market  value of a share of Common  Stock as
determined by the Board on the date of grant.

         7. Limitation on  Exercisability.  No right granted  hereunder shall be
exercisable for a period of more than five years after the date of grant.

         8. Restriction on Transfer of Options.  No Option may be transferred in
any  manner  whatsoever,  other than by the laws of  descent  and  distribution.
Options  may be  exercised  during  the  lifetime  of the  optionee  only by the
optionee.

         9.  Termination or Amendment.  The Board,  including any duly appointed
committee of the Board,  may terminate or amend the Plan at any time;  provided,
however,  that without the approval of the  shareholders  of the Company,  there
shall be (a) no increase in the total  number of shares of stock  covered by the
Plan  (except by operation  of the  provision  of Section 3, above),  and (b) no
expansion in the class of persons  eligible to receive  Options;  and  provided,
further,  that the provisions of the Plan addressing  eligibility to participate
in the Plan and the  amount,  price and timing of grants of  Options  (including
changes to the  Guidelines)  shall not be  amended  more than once every six (6)
months,  other than to comport to changes in the Internal  Revenue Code of 1986,
as amended,  or the rules  thereunder.  In any event, no amendment may adversely
affect any then outstanding Option, or any unexercised portion thereof,  without
the consent of the optionee.

                                                                      Appendix B


                              AMENDED AND RESTATED
                                3COM CORPORATION
                        1984 EMPLOYEE STOCK PURCHASE PLAN
                   (As Amended By the Board on July 22, 1998)

     1. Purpose.  The 3Com  Corporation  1984 Employee  Stock Purchase Plan (the
"Prior Plan") was established to provide eligible  employees of 3Com Corporation
("3Com")  and  any  current  or  future   subsidiary   corporation(s)   of  3Com
(collectively referred to as the "Company") with an opportunity, through payroll
deductions,  to acquire  common  stock of 3Com.  The Prior Plan has been amended
from time to time.  On September  28, 1995,  the Board of Directors of 3Com (the
"Board") amended and restated the Prior Plan as amended in order to make various
changes to the Prior Plan considered  beneficial for continuing to carry out the
purposes  of such  plan,  all in the form set forth  herein  (the  "Plan").  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").  The Company  intends 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.  Because an
eligible  employee who participates in the Plan (a  "Participant")  may withdraw
the Participant's  accumulated payroll deductions and terminate participation in
the Plan or any  Offering  (as  defined  below)  therein  at any time  during an
Offering  Period (as defined below),  the  Participant  is, in effect,  given an
option which may or may not be exercised during any Offering Period.

     2. Share  Reserve.  The maximum  number of shares which may be issued under
the Plan shall be 22,000,000  shares of 3Com's  authorized  but unissued  common
stock (the  "Shares").  In the event that any option  granted under the Plan (an
"Option") for any reason expires or is 


<PAGE>

terminated,  the Shares allocable to the unexercised  portion of such Option may
again be subjected to an Option.

     3. 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 it has been appointed.  All questions of interpretation of the Plan
or of any  Options  shall be  determined  by the  Board  and  shall be final and
binding  upon all  persons  having an  interest  in the Plan  and/or any Option.
Subject to the  provisions  of the Plan,  the Board shall  determine  all of the
relevant terms and conditions of Options granted pursuant to the Plan; provided,
however,  that all Participants  granted Options 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.

     4.  Eligibility.  Any  regular  employee  of the  Company  is  eligible  to
participate in the Plan and any Offering (as hereinafter defined) under the Plan
except the following:

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

              (b)  employees  who own or hold  options to  purchase or who, as a
result of participation in the 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 the  Company  within  the  meaning of
section 423(b)(3) of the Code; and

              (c)  with  respect  to  participation  in the  Additional  Chipcom
Offering  described in paragraph 5(a) below,  employees who were not employed by
the Company or Chipcom Corporation ("Chipcom") as of October 2, 1995.

     5.       Offerings.

              (a)  Offering  Periods  Beginning  On or After  October  1,  1995.
Effective for offerings  commencing on or after October 1, 1995,  the Plan shall
be  implemented  by  sequential  offerings  (individually,   an  "Offering")  of
approximately six (6) months duration (an "Offering 


<PAGE>

Period").  Effective  October 1, 1995,  Offerings  shall commence on April 1 and
October  1 of  each  year  and  end on the  first  September  30 and  March  31,
respectively,  occurring thereafter.  An additional Offering shall commence upon
the date  immediately  following the Effective Time (as defined in the Agreement
and  Plan of  Merger  dated  as of July  26,  1995 by and  among  3Com,  Chipcom
Acquisition  Corporation,  a  wholly-owned  subsidiary  of 3Com and Chipcom) and
shall end on March 31, 1996 (the "Additional Chipcom  Offering").  An additional
Offering shall commence upon the date  immediately  following the Effective Time
(as defined in the Amended and Restated  Agreement and Plan of Merger,  dated as
of February  26,  1997 and  amended as of March 14,  1997 by and among 3Com,  TR
Acquisitions  Corporation,  a wholly-owned  subsidiary of 3Com,  3Com (Delaware)
Corporation,  a wholly-owned  subsidiary of 3Com and U.S.  Robotics  Corporation
(the  "USR  Merger  Agreement"))  and  shall  end on  September  30,  1997  (the
"Additional  USR  Offering").  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;  provided, however, that no Offering may
exceed a term of twenty-seven  (27) months.  An employee who becomes eligible to
participate  in the Plan after an  Offering  Period 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.  The  first  day of an
Offering Period shall be the "Offering Date" for such Offering Period.  The last
day of each  Offering  Period  shall be the  "Purchase  Date" for such  Offering
Period.  In the event the first  and/or last day of an Offering  Period is not a
business day, the Company shall specify the business day that will be deemed the
first or last day, as the case may be, of the Offering Period.

              (b) Offering Periods Beginning Prior to October 1, 1995.  Offering
Periods  which  began prior to October 1, 1995 and were in effect on the date of
this amendment shall continue in effect,  subject to the terms and conditions of
the Plan as in effect immediately prior to this amendment.

<PAGE>

              (c) Governmental Approval;  Shareholder Approval.  Notwithstanding
any other provision of the Plan to the contrary,  any Option 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 Options  and/or the
Shares, and (ii) in the case of Options with an Offering Date after an amendment
to the Plan, obtaining any necessary approval of the shareholders of the Company
required in paragraph 17.

     6. Participation in the Plan.

              (a)  Initial  Participation.  An  eligible  employee  may elect to
become a Participant  effective as of the first  Offering Date after  satisfying
the  eligibility  requirements  set forth in  paragraph 4 above by  delivering a
subscription   agreement   authorizing   payroll   deductions  (a  "Subscription
Agreement") to the Company's Stock Administration  office not later than fifteen
(15)  calendar  days,  or such other period as the Company may  determine in its
sole discretion,  prior to such Offering Date. Such Subscription Agreement shall
state the eligible  employee's  election to participate in the Plan and the rate
at which payroll deductions shall be accumulated.  An eligible employee who does
not deliver a  Subscription  Agreement  to the  Company's  Stock  Administration
office at least  fifteen (15)  calendar  days, or such period as the Company may
determine  in its  sole  discretion,  prior to the  first  Offering  Date  after
becoming  eligible to participate in the Plan, shall not participate in the Plan
for that  Offering  Period or for any  subsequent  Offering  Period  unless such
employee  subsequently  enrolls in the Plan by filing a  Subscription  Agreement
with the Company in accordance with this paragraph 6(a).

              (b) Automatic Participation in Subsequent Offerings. A Participant
shall  automatically  participate in each subsequent  Offering Period until such
time as such  Participant  ceases to be eligible as provided in paragraph 4, the
Participant  withdraws  from the Plan  pursuant to  paragraph  10 below,  or the
Participant   terminates  employment  as  provided  in  paragraph  11  below.  A
Participant  is not required to file an  additional  Subscription  Agreement for
such Offering  Periods in order to  automatically  participate  therein.  Unless
otherwise indicated in a subsequently filed Subscription Agreement,  the rate at
which  payroll  deductions  



<PAGE>


shall be accumulated  with respect to any such subsequent  Offering Period shall
equal the rate applicable to the immediately preceding Offering Period.

     7. Purchase  Price.  The purchase  price at which Shares may be acquired in
any Offering  Period under the Plan 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  Period or (b) the fair market value of the Shares on the Purchase Date
of such Offering Period.  For purposes of the Plan, the fair market value of the
Shares  at any point in time  shall be  determined  by the  Board  based on such
factors as the Board deems relevant;  including, without limitation, the mean of
the bid and asked price of the Shares on the date in question as reported by the
National Association of Securities Dealers Automated Quotation System.

     8.       Payment of Purchase Price; Payroll Deductions.

              (a)  Accumulation  of Payroll  Deductions.  The purchase  price of
Shares to be acquired in an Offering Period shall be accumulated only by payroll
deductions  over the Offering  Period.  Payroll  deductions from a Participant's
compensation  on each payday during the Offering Period (i) shall not exceed ten
percent  (10%) of such  Participant's  base pay per month reduced by any payroll
deductions  from such  Participant's  compensation  to purchase  stock under any
other plan of the Company  intended to qualify as an  "employee  stock  purchase
plan" under section 423 of the Code, and (ii) shall not be less than one percent
(1%)  of  the  Participant's   base  pay  per  month.  For  purposes  hereof,  a
Participant's "base pay" from the Company is an aggregate that (i) shall include
all  salaries  and  commissions,  and (ii) shall not  include  annual  awards or
incentive  bonuses and any other  payments not  specifically  referenced  in (i)
above,  except to the extent that the inclusion of any such item with respect to
all Participants on a non-discriminatory  basis is specifically  approved by the
Board. Payroll deductions shall commence on the first payday following the first
day of a Offering Period or as soon as administratively  feasible thereafter and
shall  continue to the end of such  Offering  Period  unless  sooner  altered or
terminated as provided in the Plan.


<PAGE>

              (b) Election to Change Payroll  Deduction  Rate. A Participant may
decrease (but not increase)  the rate of payroll  deductions  with respect to an
Offering  Period only on or before and effective as of the date three (3) months
after the  beginning of such Offering  Period by filing an amended  Subscription
Agreement with the Company.  A Participant  may increase or decrease the rate of
payroll  deductions  for  any  subsequent   Offering  Period  by  filing  a  new
Subscription  Agreement  with the Company not later than fifteen  (15)  calendar
days, or such other period as the Company may determine in its sole  discretion,
prior to the beginning of such subsequent Offering Period.

              (c) Participant Accounts.  Individual accounts shall be maintained
for each Participant.  All payroll deductions from a Participant's  compensation
shall be  credited  to the  Participant's  account  under  the Plan and shall be
deposited  with the general  funds of the Company.  No interest  shall accrue on
such payroll deductions.  All payroll deductions received or held by the Company
may be used by the Company for any corporate purpose.

     9.       Purchase of Shares.

              (a) Purchase.  On the Purchase Date of each Offering Period,  each
remaining Participant shall automatically  purchase,  subject to the limitations
set forth in paragraphs 9(b) and 9(c) below, that number of whole Shares arrived
at by  dividing  the total  amount  theretofore  credited  to the  Participant's
account  pursuant to paragraph 8(c) by the purchase price  established  for such
Offering  Period  pursuant to  paragraph  7. Any cash  balance  remaining in the
Participant's  Plan  account  shall be  refunded to the  Participant  as soon as
practicable  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,  such amount shall  continue to be credited
to the  Participant's  Plan account and shall be applied  toward the purchase of
Shares  in the  immediately  subsequent  Offering  Period.  No  Shares  shall be
purchased  in  a  given  Offering  Period  on  behalf  of  a  Participant  whose
participation  in the Plan has  terminated  prior to the Purchase  Date for such
Offering Period.


<PAGE>

              (b) Share  Limitation.  Subject  to the  adjustments  set forth in
paragraph 13 below, no Participant shall be entitled to purchase more than 1,000
Shares in a single Offering.

              (c)  Fair  Market  Value  Limitation.  Notwithstanding  any  other
provision of the Plan, no Participant shall be entitled to purchase Shares under
the Plan (or any other  employee  stock  purchase plan which is intended to meet
the  requirements  of  section  423 of the  Code  sponsored  by 3Com or a parent
corporation or subsidiary  corporation of 3Com) at a rate which exceeds  $25,000
in fair  market  value (or such other  limit as may be imposed by section 423 of
the Code) for each calendar year in which the  Participant  participates  in the
Plan or any other employee  stock  purchase plan described in this sentence,  as
determined in accordance with section 423(b)(8) of the Code.

              (d) Pro Rata  Allocation.  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.

              (e) Rights as a Shareholder and Employee. A Participant shall have
no rights as a shareholder by virtue of the  Participant's  participation in the
Plan until the date of issuance of a stock  certificate(s)  for the Shares being
purchased  pursuant to the exercise of the  Participant's  Option. No adjustment
shall be made for  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.

              (f) The Company  may,  from time to time,  establish or change (i)
limitations  on the frequency  and/or  number of changes in the amount  withheld
during an Offering,  (ii) an exchange ratio  applicable to amounts withheld in a
currency  other than U.S.  dollars,  (iii)  procedures  for  permitting  unequal
percentages of payroll withholding from a Participant's compensation in order to
accommodate the Company's  established  payroll procedures or mistakes or delays
in  following  those  procedures  when  processing   Participants'   withholding



<PAGE>

elections,  and (iv) such other limitations or procedures as deemed advisable by
the Company in the Company's sole discretion  which are consistent with the Plan
and section 423 of the Code.

              (g) Any portion of a Participant's  Option  remaining  unexercised
after the end of the Offering  Period to which such right  relates  shall expire
immediately upon the end of such period.

     10.      Withdrawal.

              (a) Withdrawal  From the Plan. A Participant may withdraw from the
Plan by signing and delivering to the Company's payroll office, a written notice
of  withdrawal  on a form  provided  by  the  Company  for  such  purpose.  Such
withdrawal  may be elected at any time,  and if prior to the end of an  Offering
Period shall be effective for that Offering  Period. A Participant is prohibited
from again  participating  in an Offering upon  withdrawal  from the Plan during
such  Offering.  A  Participant  who elects to withdraw  from the Plan may again
participate  in the Plan by  filing  a new  Subscription  Agreement  in the same
manner as set forth in  paragraph  6(a) above for initial  participation  in the
Plan. 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 of time prior
to the effectiveness of the Participant's withdrawal from the Plan.

              (b) Return of Payroll  Deductions.  Upon withdrawal from the Plan,
the  accumulated  payroll  deductions  credited to a  withdrawing  Participant's
account shall be returned to the Participant and the  Participant's  interest in
the Plan shall terminate.  No interest shall accrue on the payroll deductions of
a Participant.

     11.  Termination of Employment.  Termination of a Participant's  employment
with the Company for any reason,  including  retirement or death, or the failure
of  a  Participant  to  remain  an  eligible   employee,   shall  terminate  the
Participant's participation in the Plan immediately.  Upon such termination, the
payroll  deductions  credited to the Participant's  account shall 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.  A Participant  



<PAGE>

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.

     12.  Repayment  of  Payroll  Deductions  Without  Interest.  In the event a
Participant's  interest in the Plan is terminated,  the Company shall deliver to
the Participant (or in the case of the Participant's death or incapacity, to the
Participant's  legal  representative)  the  payroll  deductions  credited to the
Participant's  account.  No interest shall accrue on the payroll deductions of a
Participant.

     13.  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 reorganization,  appropriate adjustments shall be made by
the  Company in (a) the number and class of Shares of stock  subject to the Plan
and to  any  outstanding  Option,  (b)  the  purchase  price  per  Share  of any
outstanding  Option and (c) the Share  limitation  set forth in  paragraph  9(b)
above.

     14.  Nonassignability.  Only the  Participant  may  elect to  exercise  the
Participant's  Option  during  the  Participant's  lifetime,  and no  rights  or
accumulated payroll deductions of any Participant under the Plan may be pledged,
assigned or  transferred  for any reason,  except by will or the laws of descent
and  distribution,  and any such  attempt  may be treated  by the  Company as an
election by the Participant to withdraw from the Plan.

     15.  Reports.  Each  Participant  shall  receive after the last day of each
Offering  Period a report of the  Participant's  account setting forth the total
payroll deductions accumulated, the number of Shares purchased and the remaining
cash  balance to be carried  over and/or  refunded  pursuant to  paragraph  9(a)
above, if any.

     16. 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.

         17.  Amendment or  Termination  of the Plan.  The Board may at any time
amend or terminate the Plan, except that such termination  cannot affect Options
previously granted under the Plan except as otherwise permitted by the Plan, nor
may any amendment make any change in an Option previously granted under the Plan
which would adversely  affect the right of any  Participant  except as otherwise
permitted by the Plan,  nor may any  amendment  be made without  


<PAGE>

approval of the  shareholders  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
designation of  corporations  whose  employees may be offered  Options under the
Plan.  Notwithstanding  any other provision of the Plan to the contrary,  in the
event of an  amendment  to the Plan which  affects the rights or  privileges  of
Options to be  offered  under the Plan,  each  Participant  with an  outstanding
Option shall have the right to exercise such outstanding Option on the effective
date of the amendment and to  participate  in the Plan for the remaining term of
such  outstanding  Option  pursuant to the terms and  conditions  of the Plan as
amended.  If in accordance with the preceding  sentence a Participant  elects to
exercise such  outstanding  Option and to commence  participation in the Plan as
amended on the effective date of such amendment, the Participant shall be deemed
to have received a new Option on such  effective  date,  and such effective date
shall be deemed the Offering Date for such Option.
