                                    GUARANTY

     THIS GUARANTY is entered into as of the 17th day of November 2003, by EACH
OF THE UNDERSIGNED (each a "Guarantor" and, collectively, the "Guarantors") in
favor of and for the benefit of the Administrative Agent and the Lenders parties
to the Credit Agreement referred to below, as such terms are defined in such
Credit Agreement.

                                    RECITALS

     A. Pursuant to a Credit Agreement dated as of November 17, 2003, by and
among Symbol Technologies, Inc. (the "Company"), Fleet National Bank, as
Administrative Agent and the various Lenders as are or may from time to time
become parties thereto (as the same may be amended, restated, modified or
supplemented from time to time, the "Credit Agreement"), the Company will
receive loans and other financial accommodations from the Administrative Agent
and Lenders and will incur Obligations (as defined in the Credit Agreement).

     B. The Guarantors, being members of a group of entities affiliated with the
Company and being engaged in related businesses will receive direct and indirect
benefits from such loans and financial accommodations.

     C. Each Guarantor wishes to grant the Administrative Agent and Lenders
security and assurance in order to secure the payment and performance by the
Company of all of its present and future Obligations, and, to that effect, to
guaranty the Obligations as set forth herein.

     Accordingly, each Guarantor hereby agrees as follows:

     1. GUARANTY.

     (a) Each Guarantor, jointly and severally, hereby unconditionally and
irrevocably guarantees to the Administrative Agent and the Lenders the full and
punctual payment by the Company, when due, whether at the stated due date, by
acceleration or otherwise, of all Obligations of the Company, howsoever created,
arising or evidenced, voluntary or involuntary, whether direct or indirect,
absolute or contingent now or hereafter existing or owing to the Administrative
Agent or the Lenders (collectively, the "Guaranteed Obligations"). This Guaranty
is an absolute, unconditional, irrevocable and continuing guaranty of payment
and not of collection of the Guaranteed Obligations and includes Guaranteed
Obligations arising from successive transactions which shall either continue
such Guaranteed Obligations or from time to time renew such Guaranteed
Obligations after the same have been satisfied. This Guaranty is in no way
conditioned upon any attempt to collect from the Company or any other Person or
upon any other event or contingency, and shall be binding upon and enforceable
against each Guarantor without regard to the validity or enforceability of the
Credit Agreement, the Revolving Credit Notes or any other Loan Document or of
any term of any thereof. If for any reason the Company shall fail or be unable
duly and punctually to pay any of the Guaranteed Obligations (including, without
limitation amounts that would become due but for the operation

<PAGE>

of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C.
(Section) 362(a)), each Guarantor will forthwith pay the same, in cash,
immediately upon demand.

     (b) In the event the Credit Agreement, any Revolving Credit Note or any
other Loan Document shall be terminated as a result of the rejection thereof by
any trustee, receiver or liquidating agent of the Company or any of its
properties in any bankruptcy, insolvency, reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar proceeding, each
Guarantor's obligations hereunder shall continue to the same extent as if the
Credit Agreement, such Revolving Credit Note or such other Loan Document had not
been so rejected.

     (c) Each Guarantor shall pay all costs, expenses (including, without
limitation, reasonable attorneys' fees and disbursements) and damages incurred
in connection with the enforcement of the Guaranteed Obligations of the Company
under the Credit Agreement, any Revolving Credit Note or any other Loan Document
to the extent that such costs, expenses and damages are not paid by the Company
pursuant to the respective documents, and such costs, fees and disbursements are
incurred in connection with the enforcement of the obligations of each Guarantor
under this Guaranty.

     (d) Each Guarantor further agrees that if any payment made by the Company
or any Guarantor to the Administrative Agent or the Lenders on any Obligation or
Guaranteed Obligation, as applicable, is rescinded, recovered from or repaid by
the Administrative Agent or the Lenders, in whole or in part, in any bankruptcy,
insolvency or similar proceeding instituted by or against the Company or any
Guarantor, this Guaranty shall continue to be fully applicable to such
Guaranteed Obligation to the same extent as though the payment so recovered or
repaid had never originally been made on such Guaranteed Obligation.

     (e) The Administrative Agent and the Lenders are hereby authorized at any
time and from time to time following the occurrence and during the continuance
of an Event of Default, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by the
Administrative Agent or the Lenders to or for the credit or the account of any
Guarantor against any of and all the obligations of any Guarantor now or
hereafter existing under this Guaranty, irrespective of whether or not the
Administrative Agent or any Lender shall have made any demand hereunder and
although such obligations may be unmatured. The rights under this paragraph 1(e)
are in addition to other rights and remedies (including other rights of set off)
which the Administrative Agent and the Lenders may have.

     (f) Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors.

     (g) Each Guarantor hereby agrees that to the extent that a Guarantor shall
have paid more than its proportionate share of any payment made hereunder, such
Guarantor shall be entitled to seek and receive contribution from and against
any other Guarantor hereunder

                                       2
<PAGE>

which has not paid its proportionate share of such payment. The provisions of
this Section 1(g) shall in no respect limit the obligations and liabilities of
any Guarantor to the Administrative Agent and the Lenders, and each Guarantor
shall remain liable to the Administrative Agent and the Lenders for the full
amount guaranteed by such Guarantor hereunder.

     2. GUARANTY CONTINUING, ABSOLUTE, UNLIMITED.

         The obligations of each Guarantor hereunder shall be continuing,
absolute, irrevocable, unlimited and unconditional, shall not be subject to any
counterclaim, set-off, deduction or defense (other than a defense of payment or
performance hereunder) based upon any claim any Guarantor or the Company may
have against the Administrative Agent, any Lender or the Company or any other
person, and shall remain in full force and effect without regard to, and, to the
fullest extent permitted by applicable law, shall not be released, discharged or
in any way affected by, any circumstance or condition (whether or not any
Guarantor shall have any knowledge or notice thereof) whatsoever which might
constitute a legal or equitable discharge or defense including, but not limited
to, (a) any express or implied amendment, modification or supplement to the
Credit Agreement, any Revolving Credit Note, or any other Loan Document or any
other agreement referred to in any thereof, or any other instrument applicable
to the Company or to the Revolving Credit Loans, or the Letters of Credit or any
part thereof; (b) any failure on the part of the Company to perform or comply
with the Credit Agreement, any Revolving Credit Note or any other Loan Document
or any failure of any other Person to perform or comply with any term of the
Credit Agreement, any Revolving Credit Note, or any other Loan Document or any
other agreement as aforesaid; (c) any waiver, consent, change, extension,
indulgence or other action or any action or inaction under or in respect of the
Credit Agreement, any Revolving Credit Note, or any other Loan Document or any
other agreement as aforesaid, whether or not the Administrative Agent, any
Lender, the Company or any Guarantor has notice or knowledge of any of the
foregoing; (d) any bankruptcy, insolvency, reorganization, liquidation or
similar proceeding with respect to the Company, or its properties or its
creditors, or any action taken by any trustee or receiver or by any court in any
such proceeding; (e) any furnishing or acceptance of additional security or any
release of any security; (f) any limitation on the liability or obligations of
the Company under the Credit Agreement, any Revolving Credit Note or any other
Loan Document or any termination, cancellation, invalidity or unenforceability,
in whole or in part, of the Credit Agreement, any Revolving Credit Note, this
Guaranty or any other Loan Document or any term of any thereof; (g) any lien,
charge or encumbrance on or affecting any Guarantor's or any of the Company's
respective assets and properties; (h) any act, omission or breach on the part of
the Administrative Agent or any Lender under the Credit Agreement, any Revolving
Credit Note or any other Loan Document or any other agreement at any time
existing between the Administrative Agent, any Lender and the Company or any
law, governmental regulation or other agreement applicable to the Administrative
Agent, any Lender or any Revolving Credit Loan; (i) any claim as a result of any
other dealings among the Administrative Agent, any Lender, any Guarantor or the
Company; (j) the assignment of this Guaranty, the Credit Agreement, any
Revolving Credit Note or any other Loan Document by the Administrative Agent or
any Lender to any other Person; or (k) any change in the name of the
Administrative Agent, any Lender, the Company or any other Person referred to
herein.

     3. WAIVER.

         To the fullest extent permitted by applicable law, each Guarantor
unconditionally waives: (a) notice of any of the matters referred to in Section
2 hereof; (b) all notices which may be required by statute, rule of law or
otherwise to preserve any rights against any Guarantor hereunder, including,
without limitation, notice of the acceptance of this Guaranty, or the creation,
renewal, extension, modification or accrual of the Guaranteed Obligations or
notice of any other matters relating thereto, any presentment, demand, notice of
dishonor, protest, nonpayment of any damages or other amounts payable under the
Credit Agreement, any Revolving Credit Note or any other Loan Documents; (c) any
requirement for the enforcement, assertion or exercise of any right, remedy,
power or privilege under or in respect of the Credit Agreement, any Revolving
Credit Note or any other Loan Documents, including, without limitation,
diligence in collection or protection of or realization upon the Guaranteed
Obligations or any part thereof or any collateral thereof; (d) any requirement
to mitigate the damages resulting from a default by the Company under the Credit
Agreement, any Revolving Credit Note or any other Loan Documents; (e) the right
to require the Administrative Agent or the Lenders to proceed against the
Company or any other person liable on the Guaranteed Obligations, to proceed
against or exhaust any security held by the Company or any other person, or to
pursue any other remedy in the Administrative Agent's or any Lender's power
whatsoever, and (f) the right to have the property of the Company first applied
to the discharge of the Guaranteed Obligations.

     The Administrative Agent and the Lenders may, at their election, exercise
any right or remedy they may have against the Company without affecting or
impairing in any way the liability of any Guarantor hereunder and each Guarantor
waives, to the fullest extent permitted by applicable law, any defense arising
out of the absence, impairment or loss of any right of reimbursement,
contribution or subrogation or any other right or remedy of any Guarantor
against the Company, whether resulting from such election by the Administrative
Agent or the Lenders or otherwise. Each Guarantor waives any defense arising by
reason of any disability or other defense of the Company or by reason of the
cessation for any cause whatsoever of the liability, either in whole or in part,
of the Company to the Administrative Agent and the Lenders for the Guaranteed
Obligations.

     Each Guarantor agrees that neither the Administrative Agent nor the Lenders
shall have any duty to advise any Guarantor of information regarding any
condition or circumstance of the Company or any change in such condition or
circumstance. Each Guarantor acknowledges that neither the Administrative Agent
nor the Lenders have made any representations to any Guarantor concerning the
financial condition of the Company.
