Dear Mr. Murphy:

         Aironet Wireless Communications, Inc. (the "Company") considers the
maintenance of a sound and vital management to be essential to protecting and
enhancing the best interests of the Company and its stockholders. As a publicly
held corporation, the Company recognizes the possibility that a change in its
control may arise and that the uncertainty and questions which it may raise
among management may result in the departure or distraction of management to the
detriment of the Company and its stockholders. Accordingly, in order to induce
you to remain in the employ of the Company and to secure for the Company and its
stockholders the benefits of your continued attention and dedication during the
pendency of any proposed or attempted "Change in Control" (as defined below),
including your assessment and advice to the Company's Board of Directors (the
"Board") as to whether any such proposal would be in the best interests of the
Company and its stockholders, the Compensation Committee of the Board has
determined to extend to you the severance benefits set forth in this letter
agreement (this "Agreement"), which supplements any employment agreement now
existing or hereafter entered into between you and the Company (your "Employment
Agreement", if any) and any rights or benefits to which you may be entitled
under any Plans (as defined below), in the event your employment with the
Company is terminated subsequent to a Change in Control.

         1. TERMINATION FOLLOWING A CHANGE IN CONTROL.

         If, during the period commencing with an offer or other proposal of a
transaction or event which is ultimately consummated and when consummated
constitutes a Change in Control (the "Offer Period") and ending twenty-four (24)
months after such Change in Control shall have occurred, your employment by the
Company shall be terminated (1) by the Company other than for "Cause" or
"Disability" or at normal retirement age or (2) by you for "Good Reason" (as
each of the foregoing capitalized terms is defined below), then you shall be
entitled, notwithstanding any contrary provisions of your Employment Agreement
or any Plan, to receive the following benefits:

         (a) Salary through the date of termination at the rate in effect
immediately prior thereto, plus any benefits or awards (whether to be provided
in cash, stock or other right or property) which have been earned or become
payable, but which have not yet been paid to you, pursuant to the terms of any
compensation plan, such as a bonus, incentive, stock option, restricted stock or

stock appreciation right plan, any benefit plan, such as a thrift, pension,
retirement, 401(k), profit-sharing, health, disability, accident or life
insurance plan, any vacation or relocation plan or policy or any other plan,
program or policy of the Company intended to benefit all, or any designated
group of, Company employees (each of the foregoing constituting a "Plan");

         (b) severance payment equal to twice your annual cash compensation as
in effect immediately prior to the Change in Control, payable in a lump sum at
the later of (i) five (5) days after the Change in Control or (ii) five (5) days
after termination of employment, which severance pay shall be in addition to any
severance pay which may be payable to you under your Employment Agreement, if
any; and

          (c) continued benefits (or if unavailable under the general terms and
provisions of the applicable Plan, their equivalent) for you and your
dependents, for a period terminating on the earliest of (a) two (2) years after
your employment termination, (b) the commencement date of equivalent benefits
from a new employer, or (c) your normal retirement date (after which the terms
of any retirement Plan shall govern), under all insured and self-insured
employee welfare benefit Plans in which you participated immediately prior to
such termination date, provided that you shall not be required to pay any amount
greater than the regular contribution made by you for such participation
immediately prior to such termination date.

         During any Offer Period the Company may, in its discretion, hold your
rights hereunder in abeyance until the Change in Control actually occurs.

         Except as specifically provided in Subparagraph (c) above, the amount
of any payment or benefits provided for in this Agreement shall not be reduced,
offset or subject to recovery by the Company by reason of by any compensation
earned by you as the result of your employment by another employer, by
retirement benefits, by any amount claimed to be owing by you to the Company or
otherwise.

         2. "CHANGE IN CONTROL" DEFINED.

         For purposes of this Agreement:

          (a) A "Change in Control" is deemed to have occurred when (i) any
Person after the date of this agreement becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Securities Exchange Act of 1934 (as amended, the
"Exchange Act")), directly or indirectly, of fifteen percent (15%) or more of
the combined voting power of the Company's Voting Securities or any Person who
on the date of this agreement is the beneficial owner of fifteen percent (15%)
or more of the combined voting power of the Company's Voting Securities becomes
the beneficial owner, directly or indirectly, of additional combined voting
power of Voting Securities in excess of that which is beneficially owned on the
date hereof, or (ii) the holders of the Company's

securities entitled to vote thereon approve, or there otherwise occurs or is
commenced, a sale, lease, exchange or other disposition of all or substantially
all the assets, or the dissolution or liquidation, of the Company, or any
merger, consolidation or reorganization to which the Company is a party and as
the result of which the Company's stockholders prior to the transaction do not
own at least fifty percent (50%) of the voting power of the surviving entity in
the election of directors, or (iii) "Continuing Directors" (as defined below)
cease for any reason to constitute at least a majority of the Board, or (iv) any
other event occurs which is of such a nature that would be required to be
reported as a change in control in response to Item 1(a) of the Current Report
on Form 8-K, as in effect on the date hereof pursuant to Section 13 or 15(d) of
the Exchange Act, or similar successor public filing; provided, however, that
any such event shall not be deemed to be a Change in Control as to you if it
results in you, or a group of Persons which includes you, acquiring, directly or
indirectly, fifteen percent (15%) of more of the combined voting power of the
Company's Voting Securities;

         (b) "Continuing Directors" means and includes the persons constituting
the Board as of the date of this Agreement as well as each person who becomes a
director of the Company subsequent to the date of this Agreement whose election,
or nomination for election by the Company's stockholders, was approved by an
affirmative vote of at least a majority of the then Continuing Directors (either
by a specific vote or by approval of the proxy statement of the Company in which
such person is named as a nominee for director or of the inclusion of such
person in such proxy statement as such a nominee, in any such case without
objection by any member of such approving majority of the then Continuing
Directors to the nomination of such person or the naming of such person as a
director nominee), for so long as each such director shall remain in office;

         (c) "Person" means and includes any individual, corporation,
partnership, group, association or other "person", as such term is used in
Section 14(d) of the Exchange Act, but excludes: (i) the Company; (ii) any
employee benefit plan sponsored by the Company and (iii) any Person which after
the date of this agreement becomes the beneficial owner, directly or indirectly,
of fifteen percent (15%) or more of the combined voting power of the Company's
Voting Securities and any Person who on the date of this agreement is the
beneficial owner of fifteen percent (15%) or more of the combined voting power
of the Company's Voting Securities and which hereafter becomes the beneficial
owner of additional combined voting power in excess of the that which is
beneficially owned on the date hereof, if, but only if, such voting power is not
acquired, intentionally or unintentionally, as a prelude to or in connection
with any other type of transaction, including the acquisition of additional
voting power, that would be considered a Change of Control hereunder and the
Board deems the acquisition of such voting power alone not to constitute a
Change in Control hereunder.

         (d) "Voting Securities" means the Company's Common Stock, par value
$0.01 per share, and any and all other then outstanding Company securities
ordinarily having the right to vote generally in the election of the Company's
directors.

         (a) Termination of your employment based on "Disability" means
termination because of your absence from your duties with the Company on a full
time basis for one hundred eighty (180) consecutive days as a result of your
incapacity due to physical or mental illness, unless you return to the full-time
performance of your duties within thirty (30) days after the Company gives
written notice to you of its intent to terminate your employment due to such
absence, you shall have returned to the full-time performance of your duties.

         (b) Termination of your employment for "Cause" means termination for
your dishonesty, conviction for any felony, grossly negligent or willful
misconduct in the work place, or material breach of your Employment Agreement,
if any, or of any material Company policy applicable to its employees generally.

         (c) Any of the following shall constitute "Good Reason" for you to
terminate your employment:

          (i) any change, without your prior written consent, in your status
(other than the fact that the Company may no longer be publicly traded),
positions or job responsibilities which you consider to be a reduction in, or
the assignment to you of any duties or responsibilities which you consider to be
inconsistent with, your status, positions or responsibilities as in effect
immediately prior to the Change in Control (other than as the result of your
death or the termination of your employment by the Company for Cause, Disability
or at normal retirement age or by you other than for Good Reason);

         (ii) a reduction by the Company, without your prior written consent, in
your base salary, or in the level of benefits provided to you and your
dependents under any Plan, as in effect immediately prior to the Change in

         Your right to terminate your employment pursuant to this Subparagraph
(c) shall not be affected by your incapacity due to physical or mental illness.
A termination of employment by you shall be for Good Reason if one of the
occurrences specified in this Subparagraph (c) shall have occurred,
notwithstanding that you may have an offer of employment from another employer
or any other reason(s) for terminating your employment with the Company.

         4. TAXES.

         (a) All payments to be made to you under this Agreement will be subject
to required withholding of federal, state and local income and employment taxes.

         (b) Notwithstanding anything in this Agreement to the contrary, if any
portion of any of the payments and benefits provided for in this Agreement,
together with any other payments and benefits which you have the right to
receive from the Company, its successors or any Person whose actions result in a
Change in Control, would be subject to the excise tax imposed by Section 4999 of
the Internal Revenue Code of 1986, as amended, or any successor statutory
provision ("Parachute Payments"), the Company shall pay to you, within five (5)
days of your receipt of such payments and benefits, such additional amounts as
are necessary so that, after taking into account any tax imposed by said Section
4999 or any successor statutory provision on any such Parachute Payments and on
any payments made pursuant to this Subparagraph (b), you are in the same
after-tax position in which you would have been if said Section 4999 or any
successor statutory provision did not apply and no payments were made pursuant
to this Subparagraph (b).

         5.  RESTRICTIVE COVENANTS AND ASSIGNMENT OF RIGHTS

         In consideration of the rights granted to you in this Agreement, you

Company as contemplated by this Agreement are special, unique and of
extraordinary character. You expressly agree and understand that the remedy at
law for any breach by you the Non-Competition or Confidential Information
sections of this Agreement will be inadequate and that the damages flowing from
such breach are not readily susceptible to being measured in monetary terms.
Accordingly, upon adequate proof of your violation of any legally enforceable
provision of those sections, the Company shall be entitled to immediate
injunctive relief, including, without limitation, a temporary order restraining
any threatened or further breach. In the event any equitable proceedings are
brought to enforce the provisions of any of those sections, you agree that you
will not raise in such proceedings any defense that there is an adequate remedy
at law, and you hereby waive any such defense. Nothing in this Agreement shall
be deemed to limit the Company's remedies at law or in equity for any breach by
you of any of the provisions of those sections, or of similar provisions in
other agreements between you and the Company, which may be pursued or availed of
by the Company.

opportunity to consult with your own counsel or other advisors regarding the
nature and extent of the restrictions upon you and the rights and remedies
conferred upon the Company under this Agreement, and hereby acknowledge and
agree that such restrictions are reasonable in time, territory and scope, are
designed to eliminate competition which otherwise would be unfair to the
Company, do not stifle your inherent skill and experience, would not operate as
a bar to your sole means of support, are fully required to protect the
legitimate interests of the Company and do not confer a benefit upon the Company
disproportionate to the detriment to you.

survive full payment by the Company to you of the amounts to which you is
entitled under this Agreement.

person or persons), with the Company's property or relating in any way to the
business of the Company or to the general industry of which the Company is a
part, as shall all physical embodiments and manifestations thereof, and all

obtain such patents, copyright registrations, trademark registrations or similar
protections as the Company may desire to obtain. You will immediately disclose
all Work Product to the Company and agree, at any time, upon the Company's
request and without additional compensation, to execute any documents and
otherwise to cooperate with the Company respecting the perfection of its right,
title and interest in, to and under such Work Product, and in any litigation or
controversy in connection therewith, all expenses incident thereto to be borne
by the Company.

the Company and its successors and assigns. the Company will require any
"Successor" (as defined below) to assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform under this Agreement if no such succession had taken place. Failure of
the Company to obtain such assumption and agreement within one (1) business day
after any Person becomes a Successor shall constitute Good Reason for
termination by you of your employment. For purposes of this Agreement: (i)
"Successor" shall mean any Person that, through one or a series of
transaction(s), succeeds to, or has or obtains the practical ability to control
(either immediately or with the passage of time), all or substantially all of

assets or otherwise, or indirectly, by purchase of the Company's Voting
Securities or otherwise; and (ii) the "Company" shall mean the Company as

benefit of and be enforceable by you and your personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees.

         (c) the Company expressly acknowledges and agrees that this Agreement
creates in you a contractual right to the payments and benefits provided
hereunder and expressly waives any right it may have to deny or otherwise seek
to avoid liability for any breach of its contractual obligations hereunder on
grounds of lack of consideration, accord and satisfaction or any other defense.

protecting, obtaining or enforcing any right or benefit provided by this
Agreement.
