                                     CONSENT

Reference is made to the Waiver Agreement, dated as of March 26, 2003 (the
"Waiver Agreement"), entered into by and among Symbol Technologies, Inc., a
Delaware corporation (the "Company"), the Banks party thereto, and Bank of
America, N.A., as agent for the Banks (in such capacity, the "Agent"). Unless
otherwise defined herein, capitalized terms used herein shall have the meanings,
if any, assigned to them in the Waiver Agreement.

The Banks party hereto hereby consent to the extension of the expiration date of
the Waiver Period to August 14, 2003, effective as of June 30, 2003, provided
that (i) the Company shall pay (through the Agent) to each Bank that executes
and delivers this Consent by no later than 12:00 p.m. Pacific time on Thursday,
July 3, 2003, a non-refundable waiver fee equal to $5,000, and (ii) for purposes
of Section 4(b) of the Waiver Agreement, "$90,000,000" is substituted for
"$125,000,000". The foregoing consent fee shall be fully-earned upon becoming
due and payable, shall not be refundable for any reason whatsoever and shall be
in addition to any fee, cost or expense otherwise payable by the Company
pursuant to the Credit Agreement.

Upon receipt by the Agent of (i) the consent fee referred to above for the
account of the Banks entitled thereto, and (ii) counterparts of this Consent
executed by the Company and the Majority Banks, this Consent shall become
effective.

The Company acknowledges and agrees that the execution and delivery by the Agent
and the Banks of this Consent shall not be deemed to create a course of dealing
or otherwise obligate the Agent or the Banks to provide consents, waivers or
enter into amendments under the same, similar or any other circumstances in the
future.

Except as herein expressly modified, all terms, covenants and provisions of the
Waiver Agreement are and shall remain in full force and effect.

This Consent shall be binding upon and inure to the benefit of the parties
hereto and to the Credit Agreement and their respective successors and assigns.
No third party beneficiaries are intended in connection with this Consent.

This Consent shall be governed by and construed in accordance with the laws of
the State of New York.

<PAGE>

This Consent may be executed in any number of counterparts, each of which shall
be deemed an original, but all such counterparts together shall constitute but
one and the same instrument. Each of the parties hereto understands and agrees
that this document (and any other document required herein) may be delivered by
any party thereto either in the form of an executed original or an executed
original sent by facsimile transmission to be followed promptly by mailing of a
hard copy original, and that receipt by the Agent of a facsimile transmitted
document purportedly bearing the signature of a Bank or the Company shall bind
such Bank or the Company, respectively, with the same force and effect as the
delivery of a hard copy original. Any failure by the Agent to receive the hard
copy executed original of such document shall not diminish the binding effect of
receipt of the facsimile transmitted executed original of such document of the
party whose hard copy page was not received by the Agent, and the Agent is
hereby authorized to make sufficient photocopies thereof to assemble complete
counterparty documents.

This Consent, together with the Waiver Agreement, contains the entire and
exclusive agreement of the parties hereto with reference to the matters
discussed herein and therein. This Consent supersedes all prior drafts and
communications with respect thereto. This Consent may not be amended except in
accordance with the provisions of Section 11.01 of the Credit Agreement.
