                                                                  --------------

                                    AGREEMENT
                                    ---------

                  THIS AGREEMENT (this "Agreement") is entered into as of
November 8, 1999 by and among Telxon Corporation, a Delaware corporation
("Telxon"), Cisco Systems, Inc., a California corporation ("Cisco"), and Aironet
Wireless Communications, Inc., a Delaware corporation ("Aironet"). Capitalized
terms used but not defined herein shall have the meanings ascribed to such terms
in the Merger Agreement (as defined below).

                                    RECITALS:

                  WHEREAS, Cisco and Aironet have entered into that certain
Agreement and Plan of Merger and Reorganization dated of even date herewith (the
"Merger Agreement"), pursuant to which, among other things, Cisco would acquire
Aironet pursuant to a merger of a subsidiary of Cisco with and into Aironet (the
"Merger") and Aironet stockholders would receive shares of Cisco Common Stock;

                  WHEREAS, Telxon beneficially owns approximately 35% of
Aironet's outstanding stock and as a result stands to benefit substantially from
the Merger;

                  WHEREAS, Telxon and Aironet are parties to a number of
agreements and have certain relationships which Cisco desires to terminate or
clarify in connection with entering into the Merger Agreement; and

                  WHEREAS, in order to induce Cisco to enter into the Merger
Agreement, Telxon and Aironet have agreed to enter into this Agreement.

                                   AGREEMENT:

                  NOW, THEREFORE, in consideration of the foregoing premises,
the covenants and representations set forth herein, and certain other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:

         SECTION 1. TERMINATION OF TELXON/AIRONET AGREEMENTS; EXECUTION OF
PURCHASE AND LICENSE AGREEMENTS.

                  1.1 Effective as of, and conditioned upon the occurrence of,
the Effective Time, Telxon, Aironet and Cisco agree that with no further action
on the part of any party hereto or thereto, that certain License, Rights and
Supply Agreement and that certain Services Agreement, each dated March 31, 1998,
by and between Telxon and Aironet (the "Terminated Agreements"), and all
licenses granted thereunder, shall terminate effective as of the Effective Time,
and that none of Telxon, Cisco or the Surviving Corporation shall have any
further liability or obligations with respect thereto.

                  1.2 Unless specifically contemplated by the Merger Agreement
or with the express prior written consent of Cisco, from the date hereof until
the earlier of the Effective Time or the date on which the Merger Agreement is
terminated Aironet and Telxon will not


<PAGE>   2

amend, modify or otherwise alter, or otherwise cause or permit to be amended,
modified or otherwise altered, the Terminated Agreements.

                  1.3 Effective as of, and conditioned upon the occurrence of,
the Effective Time, Cisco and Telxon will enter into a Purchase Agreement in
substantially the form attached as EXHIBIT A hereto and a License Agreement in
substantially the form attached as EXHIBIT B hereto (together, the "New
Agreements"). The New Agreements shall become effective as of, and are expressly
conditioned upon, the occurrence of the Effective Time with no further action on
the part of Cisco or Telxon; provided that in the event that the Merger
Agreement is terminated or the Merger is not consummated, the New Agreements
shall terminate and be deemed void ab initio.

                  SECTION 2. CONSENTS TO ASSIGNMENT. Effective as of the
Effective Time, Telxon hereby consents to the assignment to Cisco and the
Surviving Corporation, and any other direct or indirect Cisco subsidiary of each
of the agreements set forth on SCHEDULE 1 hereto. Such consent shall be
effective at the Effective Time whether or not the corporate existence of
Aironet ceases, including, but not limited to, as a result of the merger of
Aironet with and into Cisco (or any subsidiary of Cisco) following the Merger.
Without limiting the generality of the foregoing, Telxon hereby expressly
acknowledges that Cisco is not a "direct competitor" of Telxon for purposes of
each of the LM3000 Software Agreement and the Patent License Agreement, each
dated March 30, 1998 by and between Telxon and Aironet and the Tax Benefit and
Indemnification Agreement dated March 31, 1998 by and between Telxon and
Aironet, and any other agreement for which such acknowledgement would be
appropriate.

                  SECTION 3. NON-COMPETITION AGREEMENT.

                  3.1 As an additional material inducement for Cisco to enter
into the Merger Agreement and consummate the Merger, from and after the date
hereof and prior to the consummation of the Merger for so long as the Merger
Agreement shall remain in effect, and upon the consummation of the Merger for a
period of two (2) years after the Effective Time, Telxon will not, other than
through its ownership of Aironet stock between the date hereof and the Effective
Time, as an employer, employee, agent, consultant, advisor, independent
contractor, partner, officer, director, stockholder, investor, member, lender or
guarantor of any business corporation, partnership or other entity, or in any
other capacity, directly or indirectly, on a worldwide basis:

                           (i) design or develop any PHY and/or MAC level
                  networking devices, or acquire (by means of merger, stock
                  purchase, asset purchase or otherwise) any business that
                  designs or develops such devices, which comply with the IEEE
                  802.11 standard (including each of the various specifications
                  thereunder), and any drafts, proposals, extensions and
                  modifications to the IEEE 802.11 standard and the
                  specifications thereunder (collectively, the "Business"); or

                           (ii) permit Telxon's name to be used in connection
                  with the Business.

                                       2
<PAGE>   3


          3.2 Notwithstanding the foregoing, Telxon may beneficially own,
directly or indirectly, solely for investment purposes, up to two percent (2%)
of any class of "publicly traded securities" of any person or entity which owns
or operates a business that is competitive or substantially similar to the
Business. The term "publicly traded securities" shall mean securities that are
traded on a national securities exchange or quoted on the National Association
of Securities Dealers Automated Quotation System.

          3.3 If any restriction set forth in this Section 3 is found by a court
to be unreasonable and therefore unenforceable, or for any other reason to be
unenforceable, then Telxon agrees, and hereby submits, to the reduction and
limitation of such prohibition to such area or period as shall be deemed
enforceable.

     SECTION 4. STOCKHOLDER LAWSUIT INDEMNIFICATION.

                    (a) INDEMNIFICATION. Telxon shall indemnify and hold
harmless Cisco and the Surviving Corporation and their respective directors,
officers, representatives, agents and affiliates (within the meaning of the
Securities Act of 1933, as amended) (collectively, the "Indemnified Parties")
from and against any cost, damage, disbursement, expense, liability, judgment,
loss, deficiency, obligation, penalty or settlement of any kind or nature,
whether foreseeable or unforeseeable, including, but not limited to, interest or
other carrying costs, penalties, legal, accounting and other professional,
expert witness and consultant fees and expenses incurred in investigation,
response to collection, prosecution and defense of claims and amounts paid to
settlement (collectively, "Losses") that may be imposed on, incurred or suffered
by any Indemnified Party as a result of or in connection with the two class
action lawsuits filed by Telxon's stockholders in the court of Chancery of the
State of Delaware on May 8, 1998 or the 27 class action lawsuits filed by
Telxon's stockholders in the U.S. District Court, Northern District of Ohio from
December 1998 through March 1999, including any successor or consolidated
actions or any future lawsuits or actions arising out of or with respect to the
facts alleged in such pending actions (each, an "Action").

               4.2 PROCEDURES. If any Action indemnifiable under this Section 4
shall be brought, asserted or threatened against any person indemnified under
this Section 4, the Indemnified Party shall promptly notify the indemnifying
person ("Indemnitor"); PROVIDED that any failure to notify Indemnitor timely or
at all shall reduce the liabilities and obligations of Indemnitor under this
Section 4 only to the extent Indemnitor actually shall be prejudiced by the
failure. Indemnitor shall assume the payment of all related fees and expenses to
the Action, and Indemnitor may, at its option, assume the defense of, or respond
to, the Action. If Indemnitor has assumed the defense of (or responded to) the
Action, then the Indemnified Party shall not have the right to assume the
defense of (or respond to) the Action and, subject to the provisions of this
Section 4, Indemnitor shall have the right to control the defense, compromise or
settlement of any such Action. If Indemnitor, within 30 days after notice of any
such Action, or such shorter period as is reasonably required, fails to assume
the defense of such Action, the Indemnified Party will have the right to
undertake the defense, compromise or settlement of such Action on behalf of, and
for the account and risk, and at the expense of, Indemnitor, subject to the
right of Indemnitor to assume the defense of such Action at any time prior to
settlement, compromise or final determination thereof. The Indemnified Party
shall be bound by the result of the defense of any Action, whether the defense
shall have been assumed by Indemnitor or by

                                       3
<PAGE>   4

the Indemnified Party; PROVIDED, HOWEVER, that Indemnitor shall not enter into
any settlement or compromise of any Action or consent to the entry of any
judgment (i) which does not include as an unconditional term thereof the
delivery to the Indemnified Party, of a written release from all liability in
respect of such Action or (ii) for other than monetary damages to be borne by
Indemnitor, without the prior written consent of the Indemnified Party, which
consent shall not be unreasonably withheld. The Indemnified Party shall
cooperate fully in all aspects of any investigation, defense, pre-trial
activities, trial, compromise, settlement or discharge of any Action in respect
of which indemnity is sought pursuant to this Section 4; PROVIDED that in any
event the costs associated therewith shall also be deemed Losses hereunder.

          4.3 APPEAL. Notwithstanding anything in this Section 4 to the
contrary, if, in connection with an Action indemnifiable under this Section 4, a
court, governmental body or other authority of competent jurisdiction or other
person having authority or jurisdiction over a matter or matters related to the
Action shall have rendered, entered or granted a binding judgment, decision,
ruling, order or award with respect to the matter or matters providing for the
payment of money damages or the claimant and Indemnitor shall have agreed to
settle the Action for an amount of money damages without reservation of any
rights or defenses against the Indemnified Party, and if the Indemnified Party
elects to appeal the judgment, decision, ruling, order or award or declines to
agree to the proposed settlement, as the case may be, then the Indemnified Party
may continue to defend the Action, free of any participation by Indemnitor, but
the amount of any ultimate liability under this Section 4 with respect to Losses
related to or allegedly arising in connection with the matter or matters that
shall have been comprehended by the judgment, decision, ruling, order or award
or by the proposed settlement, as the case may be, shall then be limited to the
amount of the judgment, decision, ruling, order or award or the amount of the
proposed settlement, as the case may be.

          4.4 LIMITATION ON OTHER RIGHTS OF RECOVERY. The rights of the
Indemnified Party to indemnification as provided for in this Section 4 shall
constitute the Indemnified Party's sole remedy against Indemnitor for
indemnification with respect to an Action and Indemnitor shall have no other
liability or damages to the Indemnified Party resulting from any Action. The
provisions of this Section 4 shall not eliminate or otherwise limit the right of
any Indemnified Party hereunder or any other person to seek to recover
contribution, damages or otherwise enforce its rights against any person other
than Indemnitor without regard to the provisions of this Section 4.

     SECTION 5. MISCELLANEOUS.

          5.1 FURTHER ASSURANCES. Each party hereto, at the reasonable request
of another party hereto, shall execute and deliver such other instruments and do
and perform such other acts and things as may be necessary or desirable for
effecting completely the consummation of this Agreement.

          5.2 GOVERNING LAW AND VENUE. This Agreement shall be governed by,
construed and enforced in accordance with the laws of the State of Delaware,
without regard to conflict or choice of laws, statutes, regulations, rules or
principles. ANY ACTION RELATING TO THE EXECUTION OR PERFORMANCE OF THIS
AGREEMENT SHALL BE BROUGHT IN THE COURTS, STATE OR FEDERAL SITTING IN DELAWARE,
AND

                                       4
<PAGE>   5

EACH PARTY HERETO CONSENTS TO THE JURISDICTION AND VENUE OF SUCH COURTS, AND
AGREES NOT TO CONSENT VENUE ON THE GROUNDS OF FORUM NON CONVENIENS OR OTHERWISE.

          5.3 SEVERABILITY. In addition to the reformation provision of Section
3, if any term, provision, covenant or restriction of this Agreement is held by
a court of competent jurisdiction to be invalid, void or unenforceable, then the
remainder of the terms, provisions, covenants and restrictions of this Agreement
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated.

          5.4 BINDING EFFECT AND ASSIGNMENT. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the
rights, interests or obligations of the parties hereto may be assigned by either
of the parties without the prior written consent of the other.

          5.5 AMENDMENT AND MODIFICATION. This Agreement may not be modified,
amended, altered or supplemented except by the execution and delivery of a
written agreement executed by the parties hereto.

          5.6 SPECIFIC PERFORMANCE; INJUNCTIVE RELIEF. The parties hereto
acknowledge that Cisco will be irreparably harmed and that there will be no
adequate remedy at law for a violation of any of the covenants or agreements of
Telxon set forth herein. Therefore, it is agreed that, in addition to any other
remedies that may be available to Cisco upon any such violation, Cisco shall
have the right to enforce such covenants and agreements by specific performance,
injunctive relief or by any other means available to Cisco at law or in equity
and each of Aironet and Telxon hereby waives any requirement for the security or
posting of any bond in connection with such enforcement.

                               PURCHASE AGREEMENT

Between:                                    and:

Aironet Wireless Communications, Inc.       Telxon Corporation
3875 Embassy Parkway                        3330 West Market Street
Akron, Ohio  44333                          Akron, Ohio
(330) 664-7900
(330) 664-7922 (Fax)
("Aironet")                                 ("Buyer")


1.   PRODUCTS, PRICES, TAXES AND TERM. Aironet agrees to sell its products
     ("Products") to Buyer in available quantities for use by Buyer or sale by
     Buyer to its customers as part of ,or for use with, Buyer's finished
     products. Buyer shall place its orders for Products in writing specifying
     the Products ordered, quantity and desired shipping date. Prices for the
     Products shall be the same price Aironet charges its other customers for
     same Products in like quantities and similar terms and conditions. Prices
     are F.O.B. point of shipment, exclusive of shipping charges, federal, state
     and/or local excise, sales, use property, occupation or similar taxes. This
     agreement supersedes any terms or conditions contained in printed forms
     submitted by either party in connection with this purchase, such as
     purchase orders, sales acknowledgments or invoices, which shall be void and
     of no effect. The term of this agreement is the one year period commencing
     on the date of the last signature below, provided that the term may be
     extended by mutual written agreement of the parties. Aironet may terminate
     this agreement prior to the expiration of the term upon Telxon's material
     breach, provided that Telxon shall have five days from written notice of
     breach to cure and avoid termination.

2.   CREDIT APPROVAL AND PAYMENT TERMS. Buyer shall pay for its orders net 30
     days from the date of invoice. Aironet's invoicing and shipment of orders
     is subject to Aironet's approval of Buyer's credit. Buyer will provide
     Aironet with such financial information as Aironet reasonably requests to
     establish credit approval. Aironet may assess late charges of up to one and
     one-half percent (1 1/2%) per month or a higher rate as may be allowed by
     law. Aironet may also collect from Buyer all costs, including reasonable
     legal fees, which Aironet may incur to collect any delinquent amount.

3.   DELIVERY. Aironet will use reasonable efforts to meet the delivery dates
     specified in Buyer's orders; however, Aironet will not be liable for delays
     in delivery for any reason. Aironet will select the carrier, who will
     deliver the Products to Buyer at the location(s) shown in Buyer's orders,
     or as otherwise agreed in writing by the parties. Title and risk of loss or
     damage will pass to Buyer at Aironet's place of shipment upon delivery to
     the first carrier. Buyer may not cancel this agreement for any reason.
     Buyer may modify or cancel its orders without charge if done at least sixty
     days prior to the scheduled shipping date. Orders may not be modified or

4.   WARRANTY. Aironet warrants the Aironet manufactured products purchased
     pursuant to this agreement against defects in material and workmanship
     under normal use and service for one year from the date of shipment to
     Buyer. Aironet, at its option, will at no charge either repair, replace, or
     refund the purchase price of the Product during the warranty period
     provided it is returned in accordance with the terms of this warranty to
     the location specified by Aironet from time


                                       1
<PAGE>   11

     to time. Repair, at Aironet's option, may include the replacement of parts
     or boards with functionally equivalent reconditioned or new parts or
     boards. Replaced parts or boards are warranted for the balance of the
     original applicable warranty period. All replaced parts, boards, or Product
     shall become the property of Aironet. This warranty is extended by Aironet
     to Buyer only and is not assignable or transferable to any other party.
     Aironet is not responsible under this warranty for ancillary equipment,
     whether or not manufactured by Aironet, which is attached to or used in
     connection with the Product, nor for operation of the Product with any such
     ancillary equipment. Because each Product system is unique, Aironet
     disclaims liability for range, coverage, or operation of the system as a
     whole under this warranty. This warranty does not cover: defects or damage
     resulting from use of the Products in other than its normal and customary
     manner; defects or damage from misuse, accident or neglect; defects or
     damage from improper testing, operation, maintenance, installation,
     alteration, modification or adjustment; breakage or damage to antennas
     unless caused directly by defects in material or workmanship; product
     disassembled or repaired in such a manner as to adversely affect
     performance or prevent adequate inspection and testing to verify any
     warranty claim; or Product which has had the serial number removed or made
     illegible.

5.   PATENT AND COPYRIGHT INDEMNIFICATION. Aironet agrees to defend, at its
     expense, any suits against Buyer based upon a claim that the Products
     purchased hereunder infringe a now existing U.S. patent or copyright and to
     pay costs and damages finally awarded in any such suit, provided that
     Aironet is notified promptly in writing of the suit and Aironet is given
     sole control of said suit and is provided by Buyer with all requested
     assistance for defense of same. If the use or sale of any Products
     furnished is enjoined as a result of such suit, Aironet at its option and
     at no expense to Buyer will either (i) obtain for Buyer the right to use or
     sell the Products, (ii) substitute a substantially equivalent product or
     (iii) require the return of the Products and reimburse Buyer the purchase
     price, less a charge for reasonable wear and tear and depreciation. This
     indemnity does not extend to any suit based upon any infringement or
     alleged infringement of any patent or copyright by Products which have been
     altered by any person or entity other than Aironet or by the combination of
     any Products with other items other than when the Products are used for
     their intended purpose. This states the entire liability of Aironet for
     intellectual property infringement.

6.   FIRMWARE, MASK WORKS, SOFTWARE AND LICENSE DISCLAIMER. The Products may be
     accompanied by software, and one or more components of the Products may
     contain firmware or mask works programs built into their circuitry. Buyer's
     purchase of the Products includes a non-exclusive, royalty-free,
     non-transferable license to use such software, firmware and mask works with
     or as part of the Products, but only under the conditions prescribed by
     this Section 6. Any firmware, mask works or software which Aironet
     furnishes with the Product is subject to the following minimum conditions,
     in addition to those which may be imposed by law or other license terms
     included with the Products: (i) Aironet (or its supplier) retains all title
     and ownership to such firmware, mask works or software, and Aironet
     reserves all rights in patents, copyrights, trade secrets and other
     intellectual property in it; (ii) Buyer may not copy, disassemble,
     decompile or reverse engineer the firmware, mask works or software under
     any circumstances, nor will Buyer assist or cooperate with third parties
     attempting any of the foregoing; and (iii) Buyer will exercise the same
     care to prevent any unauthorized copying or dissemination by Buyer's
     customers and others who are to use the Products as Buyer would take to
     protect Buyer's own proprietary information, but in no event less than
     reasonable care. If Buyer



                                       2
<PAGE>   12

     ever transfers the Products to any other party, Buyer shall bind its
     transferee to the terms of this Section 6. Except for the right to use the
     software, firmware or maskworks as provided in this Section 6, nothing
     contained in this agreement shall be deemed to grant to Buyer or any other
     person or entity, either directly or by implication, estoppel, or otherwise
     any license or right under any patents, copyrights, trademarks or trade
     secrets of Aironet or any third party.

7.   WARRANTY DISCLAIMERS. THE WARRANTY GIVEN IN SECTION 4 IS LIEU OF ALL OTHER
     WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, IMPLIED
     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND
     NON-INFRINGEMENT, WHICH ARE SPECIFICALLY EXCLUDED. SECTION 4 SETS FORTH THE
     FULL EXTENT OF AIRONET'S RESPONSIBILITIES AND LIABILITY REGARDING THE
     PRODUCTS, AND REPAIR, REPLACEMENT, OR REFUND OF THE PURCHASE PRICE, AT
     AIRONET'S OPTION, IS BUYER'S EXCLUSIVE REMEDY. SECTION 5 SETS FORTH THE
     FULL EXTENT OF AIRONET'S RESPONSIBILITY AND LIABILITY REGARDING
     INTELLECTUAL PROPERTY INFRINGEMENT.

8.   CONSEQUENTIAL DAMAGES WAIVER. IN NO EVENT SHALL AIRONET BE LIABLE FOR ANY
     LOSS OF USE, LOSS OF TIME, LOST DATA, INCONVENIENCE, COMMERCIAL LOSS, LOST
     PROFITS OR SAVINGS OR OTHER INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES,
     REGARDLESS OF HOW ARISING OR WHETHER AIRONET HAS BEEN NOTIFIED OF THE
     POSSIBILITY OF SUCH DAMAGES.

9.   LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING ELSE HEREIN, ALL
     LIABILITY OF AIRONET AND ITS SUPPLIERS UNDER THIS AGREEMENT OR OTHERWISE
     SHALL BE LIMITED TO THE PURCHASE PRICE PAID TO AIRONET FOR THE AFFECTED
     PRODUCTS DURING THE SIX (6) MONTH PERIOD PRECEDING THE EVENT OR
     CIRCUMSTANCES GIVING RISE TO SUCH LIABILITY. THIS LIMITATION OF LIABILITY
     IS CUMULATIVE AND NOT PER INCIDENT.

10.  GOVERNMENT SALES. Any software or firmware which is part of or accompanies
     the Products constitutes commercial computer software programs developed at
     private expense, and to the extent that the Products or any accompanying
     software is provided to or on behalf of the United States of America, its
     agencies and/or instrumentalities (collectively, the "Government"), Buyer
     must provide such Products (A) with "restricted rights" within the meaning
     of, and use, duplication and disclosure thereof by the Government is

     Computer Licensed Program clause at 48 C.F.R. 252.227-7013 and (B) Buyer
     shall provide that the software and firmware constitute "restricted
     computer software" within the meaning of the Commercial Computer Licensed
     Program - Restricted Rights clause at 48 C.F.R. 52.227-19, as applicable,
     or as set forth in the particular department or agency regulations or rules
     which provide protection equivalent to or greater than the above cited
     clauses or any successor provisions to any of the foregoing. The
     Manufacturer/Contractor is Aironet Wireless Communications, Inc., 3875
     Embassy Parkway, Akron, Ohio 44334.

11.  COMPLIANCE WITH LAW. Buyer shall not use or transfer the Products except in
     accordance with all applicable federal, state, and local laws and
     regulations. In the event that Buyer



                                       3
<PAGE>   13

     uses or sells the Products outside of the United States, Buyer shall comply
     with all the United States export control laws and similar laws of the
     foreign county involved. The Products have been configured to operate in
     the United States unless otherwise agreed by Aironet as to any specific
     order.

12.  YEAR 2000. In reference to requests regarding "Year 2000" compliance,
     please be advised that for all Aironet products, there is no reliance upon
     any function that keeps time or calendar information. Therefore, Aironet
     products do not require any "Year 2000" specific modifications or updates
     to operate correctly before, during or after the year 2000, provided that
     all other products (for example, hardware, software and firmware) used with
     the Aironet products, properly exchange accurate data with it.

13.  GENERAL. Buyer may not assign this agreement or Buyer's rights or
     obligations hereunder without the express written consent of Aironet.
     Notices under this agreement must be sent by telegram, telex, telecopy, or
     registered or certified mail to the appropriate party at its address stated
     on the first page of this agreement (or to a new address if the other has
     been properly notified of the change). If Aironet, the notice must be
     addressed to the President of Aironet. A notice will not be effective until
     the addressee actually receives it. All terms and pricing of this agreement
     are confidential and Buyer will not disclose same without Aironet's prior
     written consent. This agreement constitutes the entire and final expression
     of agreement between the parties pertaining to the subject matter of the
     agreement and supersedes all other communications between the parties,
     including all previous oral or written communications. If any provision is
     held invalid all other provisions shall remain valid, unless such
     invalidity would frustrate the purpose of this agreement. No waiver of any
     term, or alteration or modification of the agreement will be binding upon
     either Buyer or Aironet unless made in writing and signed by an authorized
     representative of each. No failure or delay to act on any rights under this
     agreement shall be construed as a waiver of these or any other rights of
     the parties. Any term which by its nature survives the expiration or
     termination of this agreement shall so survive. This agreement shall be
     governed in accordance with the law of the state of Ohio without regard to
     conflict-of-laws principles.
