Plan"). All rights to participate in and receive benefits from the Section 16
Plan are governed solely by the terms and conditions of this Summary Plan
Description. This Summary Plan Description supercedes and replaces all prior
plan documents and summary plan descriptions governing the Section 16 Plan.

I.       EFFECTIVE DATE
The Section 16 Plan is hereby amended and restated effective September 11, 2006.

II.      ELIGIBILITY TO PARTICIPATE
Participation in the Section 16 Plan is restricted to active 3Com employees who

applicable law, as being subject to the reporting requirements of Section 16 of
the Securities Exchange Act of 1934, as amended ("Officers").

III.     ELIGIBILITY TO RECEIVE BENEFITS
Officers who are employed by the Company are eligible to receive benefits upon
the termination of their employment with 3Com under following circumstances: (a)
an involuntary termination without Cause; or (b) a Voluntary Termination for
Good Reason. The receipt of benefits under the Section 16 Plan will be
conditioned upon the Officer's execution of and compliance with an agreement
(the "Release Agreement") including, but not limited to, (i) a release of claims
against the Company, its affiliates and representatives; (ii) a non-solicitation
provision prohibiting the Officer's solicitation of any Company employee,
business opportunity, client, customer, account, distributor or vendor for a
period of one (1) year following the Termination Date; and (iii) a
non-competition provision prohibiting the Officer from directly or indirectly
engaging in, participating in or having a material ownership interest in a
business in competition with the Company. The form and language of the Release
Agreement shall be determined by the Company in its sole discretion.

IV.      BENEFITS
Officers who are eligible to receive benefits under the Section 16 Plan will be
entitled to receive the following upon their execution of the Release Agreement:

         A.       Severance Amounts.

as of the Termination Date, subject to all applicable taxes and withholdings;
and

                  2.       A pro-rated amount of the Officer's earned incentive
bonus for the bonus period in which the Termination Date occurs, to be
calculated by multiplying the earned bonus amount (based on the Company's actual
attainment of applicable performance metrics) by a fraction, the numerator of
which shall be the number of calendar days between the beginning of the
applicable bonus period to the Termination Date and the denominator of which
shall be the number of calendar days within the applicable bonus period, payable

         B.       Health, Dental & Vision Benefits. Continuation of coverage
under the Company's health, dental, and vision insurance plans ("Health Care
Plans") pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985
("COBRA") at the same level of coverage as was provided to and elected by the
Officer as of the Termination Date. If the Officer timely and properly elects to
continue coverage under the Company's Health Care Plans in accordance with
COBRA, the Company shall continue to pay the Company-paid portion of the
premiums for the Officer's elected coverage under the Health Care Plans until
the earlier of: (i) one (1) year from the Termination Date, or (ii) the date

premium(s) is subject to change at the Company's discretion. To be eligible for
continuation of coverage under the Health Care Plans, an Officer must be
actively enrolled in the applicable Health Care Plan(s) as of the Termination
Date. For purposes of Title X of COBRA, the date of the "qualifying event" for
the Officer and his/her covered dependents shall be the Termination Date, and
each month of Company-sponsored coverage continuation provided hereunder shall
offset a month of coverage continuation otherwise due under COBRA. Upon the
expiration of the one (1) year period, the Officer will be required to pay 102%
of the premium to continue Company-sponsored coverage. Any continuation of
Company-sponsored coverage shall be governed by COBRA and the terms and
conditions of the applicable plan documents.

         C.       Life Insurance.  Conversion of the Officer's basic term life
insurance in effect immediately prior to the Termination Date to continue
coverage until the earlier of (i) one (1) year from the Termination Date, or
(ii) the date upon which the Officer becomes eligible for coverage under another
employer's life insurance plan.

         D.       Equity Compensation.

stock options, restricted stock, and restricted stock units issued to the
Executive that are subject to time-based vesting. The accelerated vesting
provided for herein will be effective as of the Termination Date.

                  2.       Extension of the exercise period for vested stock
options issued to the Executive to the earlier of: (i) one hundred and
sixty-five (165) calendar days from the Termination Date; or (ii) the original
term of the stock option grant.

All other compensation (including, without limitation, salary, bonuses and
commissions) and employee benefits (including, without limitation, short-term
and long-term disability insurance, Paid Time Off accrual, and vesting of equity
compensation) will cease on the Officer's Termination Date. Payments under the
Section 16 Plan will not be subject to 401(k) or Employee Stock Purchase Plan
deductions. Except as provided herein, all equity compensation grants are
subject to the terms and conditions of the applicable plan document(s).

Plan, or a benefit in an amount greater than he/she has received, the Officer
may file a claim by writing to the Section 16 Plan Administrator. The Section 16
Plan Administrator is the named fiduciary that has the discretionary power and

<PAGE>

         A.       Initial Claim. The Section 16 Plan Administrator will notify
the Officer in writing within ninety (90) days (or 180 days if special
circumstances require an extension of time for processing the claim) of receipt
of the claim as to whether the claim is granted or denied. Note that if an
extension is necessary, the Section 16 Plan Administrator will provide the
Officer with written notice of the extension (including the circumstances
requiring extension and date by which a decision is expected to be rendered)
before the initial ninety (90) day period expires. If the claim is denied, the
Officer will be given (1) specific reasons for the denial, (2) specific
reference to the Section 16 Plan provision(s) on which the denial is based, (3)
a description of any information or material necessary to support the claim and
an explanation of why such information or material is necessary, (4) an
explanation of the Section 16 Plan's claim appeal procedure (including a
statement of the Officer's right to bring a civil action under the Employee
Retirement Income Security Act of 1974 ("ERISA") following a denial of the claim
upon appeal), and (5) a statement that the Officer is entitled to receive, upon
request and free of charge, reasonable access to, and copies of all documents,
records or other information relevant (as defined by Department of Labor
regulation section 2560.503-1(m)) to the claim.

         B.       Appeals. If the claim is denied, the Officer has sixty (60)
days after notice of the denial to file a written appeal with the Section 16
Plan Administrator. During the review process, the Officer has the right to
submit written comments, documents, records, and other information relating to
the claim for benefits, which will be considered without regard to whether such
items were considered in the initial benefit determination. Also, the Officer
may, upon request and free of charge, have reasonable access to, and copies of,
all documents, records and other information relevant (as defined by Department
of Labor regulation section 2560.503-1(m)) to the claim for benefits.

         The Section 16 Plan Administrator will notify the Officer in writing
within sixty (60) days (or 120 days if special circumstances require an
extension of time for processing the appeal) of receipt of the appeal as to its
decision on review, unless the Section 16 Plan Administrator determines that
special circumstances exist requiring an extension of time. If the Section 16
Plan Administrator determines that an extension is necessary, the Section 16
Plan Administrator will provide the Officer with written notice (including the
circumstances requiring the extension and date by which a decision is expected
to be rendered) before the initial sixty (60) day period expires.

         If the Section 16 Plan Administrator denies the appeal, it will provide
a written denial of the claim upon appeal. The written denial shall include the
specific reason or reasons for the denial, specific references to the Section 16
Plan provisions on which the denial is based, a statement that the Officer is
entitled to receive, upon request and free of charge, reasonable access to, and
copies of all documents, records or other information relevant (as defined in
Department of Labor regulation section 2560.503-1(m)) to the claim, and a
statement of the Officer's right to bring an action under Section 502(a) of
ERISA.

         All determinations, interpretations, rules, and decisions of the
Section 16 Plan Administrator or its delegate shall be conclusive and binding
upon all persons having or claiming to have any interest or right under the
Section 16 Plan and shall be given deference in any judicial or other
proceeding.

         C.       Exhaustion of Claims Procedures. In no event shall an Officer
or any other person be entitled to challenge a decision of the Section 16 Plan
Administrator in court or in any other administrative proceeding unless and
until the claim and appeal procedures described above have been fully complied
with and exhausted.

XVI.     ERISA RIGHTS
If you are an eligible Officer who is a participant in the Section 16 Plan, you
are entitled to certain rights and protections under ERISA.

Receive Information About Your Plan and Benefits. ERISA provides that you are
entitled to:

         (1)      Examine, without charge, at the office of the Section 16 Plan
                  Administrator or its delegate all Section 16 Plan documents,
                  including copies of any documents filed by the Section 16 Plan
                  with the U.S. Department of Labor, such as Section 16 Plan
                  descriptions.

         (2)      Obtain copies of all Section 16 Plan documents and other
                  Section 16 Plan information upon written request to the
                  Section 16 Plan Administrator. The Section 16 Plan
                  Administrator may impose a reasonable charge for the copies.

         (3)      Receive a copy of the Section 16 Plan's financial report, if
                  any. The Section 16 Plan Administrator may be required by law
                  to furnish each participant with a copy of the summary annual
                  report.

Prudent Actions By Fiduciaries. In addition to creating rights for the Section
16 Plan participants, ERISA imposes duties upon the people who are responsible
for the operation of the Section 16 Plan. The people who operate the Section 16
Plan, called "fiduciaries" of the Section 16 Plan, have a duty to do so
prudently and in the interest of you and other Section 16 Plan participants and
beneficiaries.

No one may fire you or otherwise discriminate against you in any way to prevent
you from obtaining a benefit or exercising your rights under ERISA.

Enforce Your Rights. If your claim for any Section 16 Plan benefit is denied or
ignored, in whole or in part, you have a right to know why this was done, to
obtain copies of documents relating to the decision without charge, and to
appeal any denial, all within certain time schedules.

Under ERISA, there are steps you can take to enforce the above rights. For
instance, if you request materials from the Section 16 Plan and do not receive
them within thirty (30) days, you may file suit in a federal court. In such
case, the court may require the Section 16 Plan Administrator to provide the


                                       6

3Com Corporation Section 16 Officer Severance Plan  Amended and Restated 9/11/06
<PAGE>

materials and pay you up to $110 a day until you receive the materials, unless
the materials were not sent because of reasons beyond the control of the Section
16 Plan Administrator.

If you have a claim for a benefit that is denied or ignored, in whole or in
part, you may file suit in a state or federal court. If it should happen that
Section 16 Plan fiduciaries misuse the Section 16 Plan's money, or if you are
discriminated against for asserting your rights, you may seek assistance from
the U.S. Department of Labor or you may file suit in a federal court. The court
will decide who should pay court costs and legal fees. If you are successful,
the court may order the person you have sued to pay these costs and fees. If you
lose, the court may order you to pay these costs and fees, for example, if it
finds your claim is frivolous.

Assistance With Your Questions. If you have questions about the statements made
in this summary or your rights under ERISA, you should contact the Section 16
Plan Administrator or the nearest Area Office of the Employee Benefits Security
Administration, U.S. Department of Labor, listed in your telephone directory, or
the Division of Technical Assistance and Inquiries, Pension and Welfare Benefits
Administration, U.S. Department of Labor, 200 Constitution Avenue, Washington,
D.C. 20210.
