                                                                          TIER I

                                  PC-TEL, INC.

                         MANAGEMENT RETENTION AGREEMENT

     This Management Retention Agreement (the "Agreement") is made and entered
into by and between ________________________ (the "Executive") and PC-Tel, Inc.
(the "Company"), effective as of the latest date set forth by the signatures of
the parties hereto below (the "Effective Date").

                                R E C I T A L S
                                ---------------

     A.  It is expected that the Company from time to time may consider a Change
of Control (as defined below).  The Board of Directors of the Company (the
"Board") recognizes that such consideration can be a distraction to the
Executive and can cause the Executive to consider alternative employment
opportunities.  The Board has determined that it is in the best interests of the
Company and its stockholders to assure that the Company will have the continued
dedication and objectivity of the Executive, notwithstanding the possibility,
threat or occurrence of a Change of Control of the Company.

     B.  The Board believes that it is in the best interests of the Company and
its stockholders to provide the Executive with an incentive to continue his
employment and to motivate the Executive to maximize the value of the Company
upon a Change of Control for the benefit of its stockholders.

     C.  The Board believes that it is imperative to provide the Executive with
severance benefits upon Executive's termination of employment following a Change
of Control which provides the Executive with enhanced financial security and
incentive and encouragement to remain with the Company notwithstanding the
possibility of a Change of Control.

     D.  Certain capitalized terms used in this Agreement are defined in Section
5 below.

     The parties hereto agree as follows:

     1.  Term of Agreement.  This Agreement shall terminate upon the date that
         -----------------
all obligations of the parties hereto with respect to this Agreement have been
satisfied.

     2.  At-Will Employment.  The Company and the Executive acknowledge that the
         ------------------
Executive's employment is and shall continue to be at-will, as defined under
applicable law, and may be terminated by either party at any time, with or
without cause or notice.  If the Executive's employment terminates for any
reason, including (without limitation) any termination prior to a Change of
Control, the Executive shall not be entitled to any payments, benefits, damages,
awards or compensation other than as provided by this Agreement, or as may
otherwise be available in
<PAGE>

accordance with the Company's established employee plans or pursuant to other
written agreements with the Company.

     3.  Change of Control Severance Benefits.
         ------------------------------------

         (a)  Involuntary Termination other than for Cause, Death or Disability
              -----------------------------------------------------------------
or Voluntary Termination for Good Reason Following A Change of Control. If,
----------------------------------------------------------------------
within twelve (12) months following a Change of Control, Employee's employment
is terminated (i) involuntarily by the Company other than for Cause, death or
Disability or (ii) by the Executive pursuant to a Voluntary Termination for Good
Reason, then, subject to Executive entering into a standard form of mutual
release of claims with the Company, the Company shall provide Executive with the
following benefits upon such termination:

              (i)   Severance Payment.  A lump-sum cash payment in an amount
                    -----------------
equal to two hundred percent (200%) of the Executive's Annual Compensation;

              (ii)  Continued Executive Benefits.  Company-paid health, dental,
                    ----------------------------
vision, long-term disability and life insurance coverage at the same level of
coverage as was provided to such Executive immediately prior to the Change of
Control and at the same ratio of Company premium payment to Executive premium
payment as was in effect immediately prior to the Change of Control (the
"Company-Paid Coverage"). If such coverage included the Executive's dependents
immediately prior to the Change of Control, such dependents shall also be
covered at Company expense. Company-Paid Coverage shall continue until the
earlier of (A) one year from the date of termination, or (B) the date upon which
the Executive and his dependents become covered under another employer's group
health, dental, vision, long-term disability or life insurance plans that
provide Executive and his dependents with comparable benefits and levels of
coverage. For purposes of Title X of the Consolidated Budget Reconciliation Act
of 1985 ("COBRA"), the date of the "qualifying event" for Executive and his or
her dependents shall be the date upon which the Company-Paid Coverage commences,
and each month of Company-Paid Coverage provided hereunder shall offset a month
of continuation coverage otherwise due under COBRA.

              (iii) Pro-Rated Bonus Payment.   A lump-sum cash payment equal to
                    -----------------------
one hundred percent (100%) of the higher of (A) Executive's Target Bonus as in
effect for the fiscal year in which the Change of Control occurs or (B)
Executive's Target Bonus as in effect for the fiscal year in which Executive's
termination occurs, pro-rated by multiplying such bonus amount in clause (A) or
(B), as applicable, by a fraction, the numerator of which shall be the number of
days prior to Executive's termination during such fiscal year, and the
denominator of which shall be three-hundred and sixty-five.

              (iv)  Equity Compensation Accelerated Vesting. One Hundred
                    ---------------------------------------
percent (100%) of the unvested portion of any stock option, restricted stock or
other Company equity compensation held by the Executive shall be automatically
accelerated in full so as to become completely vested.

         (b)  Voluntary Resignation.  If the Executive's employment terminates
              ---------------------
by reason of the Executive's voluntary resignation (and is not a Voluntary
Termination for Good Reason), then
<PAGE>

the Executive shall not be entitled to receive severance or other benefits
except for those (if any) as may then be established under the Company's then
existing severance and benefits plans or pursuant to other written agreements
with the Company.

         (c)  Disability; Death.  If the Employee's employment with the Company
              -----------------
terminates as a result of the Executive's Disability, or if Executive's
employment is terminated due to the death of the Executive, then the Executive
shall not be entitled to receive severance or other benefits except for those
(if any) as may then be established under the Company's then existing severance
and benefits plans or pursuant to other written agreements with the Company.

         (d)  Termination for Cause.  If the Executive is terminated for Cause,
              ---------------------
then the Executive shall not be entitled to receive severance or other benefits.

         (e)  Termination Apart from Change of Control.  In the event the
              ----------------------------------------
Executive's employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the twelve (12) month period
following a Change of Control, then the Executive shall be entitled to receive
severance and any other benefits only as may then be established under the
Company's then existing severance and benefits plans or pursuant to other
written agreements with the Company.

     4.  Definition of Terms.  The following terms referred to in this Agreement
         -------------------
shall have the following meanings:

         (a)  Annual Compensation.  "Annual Compensation" shall mean an amount
              -------------------

              -----
taken by the Executive in connection with his responsibilities as an employee
and intended to result in substantial personal enrichment of the Executive, (ii)
Executive being convicted of a felony, (iii) a willful act by the Executive
which constitutes gross misconduct and which is injurious to the Company, (iv)
following delivery to the Executive of a written demand for performance from the
Company which describes the basis for the Company's reasonable belief that the
Executive has not substantially performed his duties, continued violations by
the Executive of the Executive's obligations to the Company which are
demonstrably willful and deliberate on the Executive's part.

         (d)  Change of Control.  "Change of Control" means the occurrence of
              -----------------
any of the following events:

              (i)    Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing fifty percent (50%) or

              (iii)  The consummation of a merger or consolidation of the
Company with any other corporation, other than a merger or consolidation which
would result in the voting securities of the Company outstanding immediately
prior thereto continuing to represent (either by remaining out-standing or by
being converted into voting securities of the surviving entity or its parent) at
least fifty percent (50%) of the total voting power represented by the voting
securities of the Company or such surviving entity or its parent outstanding
immediately after such merger or consolidation; or

              (iv)   A change in the composition of the Board occurring within a
two-year period, as a result of which fewer than a majority of the directors are
Incumbent Directors. "Incumbent Directors" shall mean directors who either (A)
are directors of the Company as of the date upon which this Agreement was
entered into, or (B) are elected, or nominated for election, to the Board with
the affirmative votes of at least a majority of those directors whose election
or nomination was not in connection with any transaction described in
subsections (i), (ii), or (iii) above, or in connection with an actual or
threatened proxy contest relating to the election of directors to the Company.

         (e)  Disability. "Disability" shall mean that the Executive has been
              ----------
unable to perform his Company duties as the result of his incapacity due to
physical or mental illness, and such in-ability, at least 26 weeks after its
commencement, is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative (such Agreement as to acceptability not to be unreasonably
withheld). Termination resulting from Disability may only be effected after at
least 30 days' written notice by the Company of its intention to terminate the
Employee's employment. In the event that the Executive resumes the performance
of substantially all of his duties hereunder before the termination of his
employment becomes effective, the notice of intent to terminate shall

responsibilities, relative to the Executive's duties, title, authority or
responsibilities as in effect immediately prior to such reduction, or the
assignment to Executive of such reduced duties, title, authority or
responsibilities; provided, however, that a reduction in duties, title,
authority or responsibilities solely by virtue of the Company being acquired and
made part of a larger entity (as, for example, when the senior vice-president of
a business unit of the Company remains as such following a Change of Control)
shall not by itself constitute grounds for a "Voluntary Termination for Good
Reason;" (ii) without the Executive's express written consent, a material
reduction, without good business reasons, of the facilities and perquisites
(including office space and location) available to the Executive immediately
prior to such reduction; (iii) a reduction by the Company in the base salary of
the Executive as in effect immediately prior to such reduction; (iv) a material
reduction by the Company in the aggregate level of employee benefits, including
bonuses, to which the Executive was entitled immediately prior to such reduction

the Executive to a facility or a location more than thirty-five (35) miles from
the Executive's then present location, without the Executive's express written
consent; (vi) the failure of the Company to obtain the assumption of this
agreement by any successors contemplated in Section 6(a) below; or (vii) any act
or set of facts or circumstances which would, under California case law or
statute constitute a constructive termination of the Executive.

     5.  Non-Solicitation. In consideration for the severance benefits Executive
         ----------------
is to receive herein, if any, Executive agrees that he or she will not, at any
time during the one year following his or her termination date, directly or

otherwise) to all or substantially all of the Company's business and/or assets
shall assume the obligations under this Agreement and agree expressly to perform
the obligations under this Agreement in the same manner and to the same extent
as the Company would be required to perform such obligations in the absence of a
succession. For all purposes under this Agreement, the term "Company" shall
include any such successor to the Company which executes and delivers the
assumption agreement described in this Section 6(a) or which becomes bound by
the terms of this Agreement by operation of law.

         (b)  Executive's Successors. The terms of this Agreement and all rights

specific termination provision in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision so indicated, and shall specify the termination
date (which shall be not more than

30 days after the giving of such notice). The failure by the Executive to
include in the notice any fact or circumstance which contributes to a showing of
Voluntary Termination for Good Reason shall not waive any right of the Executive
hereunder or preclude the Executive from asserting such fact or circumstance in
enforcing his rights hereunder.

     8.  Miscellaneous Provisions.
         ------------------------

         (a)  No Duty to Mitigate. The Executive shall not be required to
