                                    GUARANTY


         This GUARANTY (this "Guaranty"), made this 18th day of March, 1998, by
Community Redevelopment Corporation, a Florida corporation (the "Guarantor") in
favor of Foothill Capital Corporation, a California corporation (the "Agent"),
as agent for the Lenders (as defined below),

                              W I T N E S S E T H:

         WHEREAS, Source One Wireless, Inc., a Delaware corporation (the
"Borrower"), the financial institutions listed on the signature pages thereof
(such financial institutions, together with their respective successors and
assigns, being hereinafter each referred to as a "Lenders" and collectively as
the "Lenders") and the Agent are parties to that certain Loan and Security
Agreement dated September 8, 1997, as amended by that certain First Amendment to
Loan and Security Agreement dated January 30, 1998 (as the same may hereafter be
modified, amended, restated or supplemented from time to time, the "Loan
Agreement"), pursuant to which the Lenders have agreed to extend credit to the
Borrower from time to time and the Borrower has granted a security interest in
all of its assets to the Agent for the benefit of the Lender Group (as defined
in the Loan Agreement); and

         WHEREAS, Guarantor is a Subsidiary (as defined in the Loan Agreement)
of the Borrower, and Guarantor will realize substantial direct and indirect
benefits as a result of the extensions of credit to the Borrower pursuant to the
Loan Agreement; and

         WHEREAS, the Lender Group has required that the Guarantor execute and
deliver this Guaranty to the Agent (i) as a condition precedent to the execution
of the Second Amendment to the Loan and Security Agreement of even date
herewith, (ii) in order to secure the prompt and complete payment, observance
and performance of all of the Obligations (as defined in the Loan Agreement) and
(iii) as a condition precedent to the continued extension of credit under the
Loan Agreement; and

         WHEREAS, the obligations of the Guarantor hereunder are secured by
security interests granted to the Agent by the Guarantor pursuant to that
certain Subsidiary Security Agreement of even date herewith (the "Subsidiary
Security Agreement") between the Agent and the Guarantor and by the other Loan
Documents (as defined in the Loan Agreement) to which the Guarantor is a party;

         NOW, THEREFORE, for and in consideration of the recitals made above,
Ten Dollars ($10.00) in hand paid and other good and valuable consideration, the
receipt, sufficiency and adequacy of which are hereby acknowledged, the
Guarantor hereby agrees that capitalized terms used herein and not otherwise
defined herein are used as defined in the Loan Agreement, and further agrees as
follows:

         1. Guarantor hereby guarantees, subject to the limitations set forth in
Section 7 hereof, to the Agent for the benefit of the Lender Group, the full and
prompt payment of the Obligations pursuant to the Loan Agreement and every other
Loan Document, including any interest thereon, plus actual and reasonable
attorneys' fees and expenses if the obligations represented by this Guaranty are
collected by law, through an attorney-at-law, or under advice therefrom.

<PAGE>


         2. Regardless of whether any proposed guarantor or any other Person
shall become in any other way responsible to the Agent or the Lenders, or any of
them, for or in respect of the Obligations or any part thereof, and regardless
of whether or not any Person now or hereafter responsible to the Agent or the
Lenders, or any of them, for the Obligations or any part thereof, whether under
this Guaranty or otherwise, shall cease to be so liable, the Guarantor hereby
declares and agrees that this Guaranty shall be a joint and several obligation,
shall be a continuing guaranty and shall be operative and binding until the
Obligations shall have been indefeasibly paid or performed in full and the
Lenders shall be under no further obligation to extend any additional credit
under the Loan Agreement.

         3. Upon this Guaranty's being executed and coming into the hands of the
Agent, this Guaranty shall be deemed to be finally executed and delivered by the
Guarantor and shall not be subject to or affected by any promise or condition
affecting or limiting the Guarantor's liability, except as stated in the Loan
Agreement, and no statement, representation, agreement or promise on the part of
the Agent, the Lenders, the Borrower, or any of them, or any officer, employee
or agent thereof, unless contained herein, forms any part of this Guaranty or
has induced the making thereof or shall be deemed in any way to affect the
Guarantor's liability hereunder. The Guarantor absolutely, unconditionally and
irrevocably waives any and all right to assert any defense, set-off,
counterclaim or cross-claim of any nature whatsoever with respect to this
Guaranty or the obligations of the Guarantor under this Guaranty or the
obligations of any other Person or party (including, without limitation, the
Borrower) relating to this Guaranty or the obligations of the Guarantor under
this Guaranty or otherwise with respect to the Obligations in any action or
proceeding brought by the Agent hereof to collect the Obligations or any portion
thereof, or to enforce the obligations of the Guarantor under this Guaranty.

         4. The Agent or the Lenders, or any of them, may from time to time,
without exonerating or releasing the Guarantor in any way under this Guaranty,
(i) take such further or other security or securities for the Obligations or any
part thereof as it may deem proper, or (ii) release, discharge, abandon or
otherwise deal with or fail to deal with the Guarantor of the Obligations or any
security or securities therefor or any part thereof now or hereafter held by the
Agent or any of the Lenders, or (iii) amend, modify, extend, accelerate or waive
in any manner any of the provisions, terms, or conditions of the Loan Documents,
all as it may consider expedient or appropriate in its sole discretion. Without
limiting the generality of the foregoing, or of Section 5 hereof, it is
understood that the Agent or the Lenders, or any of them, may, without
exonerating or releasing the Guarantor, give up, or modify or abstain from
perfecting or taking advantage of any security for the Obligations and accept or
make any compositions or arrangements, and realize upon any security for the
Obligations when, and in such manner, and with or without notice, all as such
Person may deem expedient.

         5. The Guarantor acknowledges and agrees that no change in the nature
or terms of the Obligations or any of the Loan Documents, or other agreements,
instruments or contracts evidencing, related to or attendant with the
Obligations (including any novation), shall discharge all or any part of the
liabilities and obligations of the Guarantor pursuant to this Guaranty; it being
the purpose and intent of the Guarantor and the Agent that the covenants,
agreements and all liabilities and obligations of the Guarantor hereunder are
absolute, unconditional and irrevocable under any and all circumstances. Without
limiting the generality of the foregoing, the Guarantor agrees that until each
and every one of the covenants and agreements of this Guaranty is fully
performed, and without possibility of recourse, whether by operation of law or
otherwise, the Guarantor's undertakings hereunder shall not be released, in
whole or in part, by any action or thing which might, but for this paragraph of
this Guaranty,


                                       -2-
<PAGE>


be deemed a legal or equitable discharge of a surety or guarantor, or by reason
of any waiver, omission of the Agent or any Lender, or any of them, or its or
their failure to proceed promptly or otherwise, or by reason of any action taken
or omitted by the Agent or any Lender, or any of them, whether or not such
action or failure to act varies or increases the risk of, or affects the rights
or remedies of, the Guarantor or by reason of any further dealings between the
Borrower on the one hand and the Agent or any Lender, on the other hand or any
other guarantor or surety, and the Guarantor hereby expressly waives and
surrenders any defense to its liability hereunder, or any right of counterclaim
or offset of any nature or description which it may have or may exist based
upon, and shall be deemed to have consented to, any of the foregoing acts,
omissions, things, agreements or waivers.

         6. The Agent and each of the Lenders may, without demand or notice of
any kind upon or to the Guarantor, at any time or from time to time when any
amount shall be due and payable hereunder by the Guarantor, if the Borrower
shall not have timely paid any of the Obligations, set-off and appropriate and
apply to any portion of the Obligations hereby guaranteed, and in such order of
application as the Agent or such Lender may from time to time elect in
accordance with the Loan Agreement, any deposits, property, balances, credit
accounts or moneys of the Guarantor in the possession of the Agent or such
Lender, or under their respective control for any purpose.

         7. The creation or existence from time to time of Obligations in excess
of the amount committed to or outstanding on the date of this Guaranty is hereby
authorized, without notice to the Guarantor, and shall in no way impair or
affect this Guaranty or the rights of the Agent herein. Anything herein to the
contrary notwithstanding, the liability of the Guarantor hereunder shall not
exceed the amount which would be enforceable in a bankruptcy, insolvency or
other similar proceeding giving effect to fraudulent conveyance and other
similar laws relating to the insolvency of debtors.

         8. Upon the bankruptcy or winding up or other distribution of assets of
the Borrower or of any surety or guarantor (other than the Guarantor) for any
Obligations of the Borrower to the Agent and the Lenders, the rights of the
Agent against the Guarantor shall not be affected or impaired by the omission of
the Agent or any Lender to prove its claim, or to prove the full claim, as
appropriate, and the Agent may prove such claims as it sees fit and may refrain
from proving any claim and in its discretion may value as it sees fit or refrain
from valuing any security held by it without in any way releasing, reducing or
otherwise affecting the liability to the Agent of the Guarantor.

         9. Any amount received by the Agent from whatsoever source and applied
toward the payment of the Obligations shall be applied in accordance with the
terms of the Loan Agreement.

         10. The Guarantor hereby absolutely, unconditionally and irrevocably
expressly waives, except to the extent such waiver would be expressly prohibited
by applicable law, the following: (a) notice of acceptance of this Guaranty, (b)
notice of the existence or creation of all or any of the Obligations, (c)
presentment, demand, notice of dishonor, protest and all other notices
whatsoever, (d) all diligence in collection or protection of or realization upon
the Obligations or any part thereof, any obligation hereunder, or any security
for any of the foregoing, (e) all rights to enforce any remedy which the Agent
or the Lenders, or any of them, may have against the Borrower, and (f) all
rights of subrogation, indemnification, contribution and reimbursement from the
Borrower and any benefit of, or right to participate in, any collateral or
security now or hereinafter held by the Agent or the Lenders, or any of them, in
respect of the Obligations. If a claim is ever made upon the Agent or any of the
Lenders for


                                      -3-
<PAGE>


the repayment or recovery of any amount or amounts received by such Person in
payment of any of the Obligations and such Person repays all or part of such
amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over such Person or any of its property,
or (b) any settlement or compromise of any such claim effected by such Person
with any such claimant, including the Borrower, then in such event the Guarantor
agrees that any such judgment, decree, order, settlement or compromise shall be
binding upon the Guarantor, notwithstanding any revocation hereof or the
cancellation of any promissory note or other instrument evidencing any of the
Obligations, and the Guarantor shall be and remain obligated to such Person
hereunder for the amount so repaid or recovered to the same extent as if such
amount had never originally been received by such Person.

         11. The Agent and the Lenders may, to the extent permitted under the
Loan Agreement, sell, assign or transfer all or any part of the Obligations, and
in such event each and every permitted assignee, transferee, or holder of all or
any of the Obligations, shall have the right to enforce this Guaranty, by suit
or otherwise, for the benefit of such permitted assignee, transferee or holder
as fully as if such assignee, transferee or holder were herein by name
specifically given such rights, powers and benefits.

         12. This Guaranty is a continuing guaranty of the Obligations and all
liabilities to which it applies or may apply under the terms hereof and shall be
conclusively presumed to have been created in reliance hereon. No failure or
delay by the Agent in the exercise of any right, power, privilege or remedy
shall operate as a waiver thereof, and no single or partial exercise by the
Agent of any right or remedy shall preclude other or further exercise thereof or
the exercise of any other right or remedy and no course of dealing between the
Guarantor and the Agent or any Lender shall operate as a waiver thereof. No
action by the Agent permitted hereunder shall in any way impair or affect this
Guaranty. For the purpose of this Guaranty, the Obligations shall include,
without limitation, all Obligations of the Borrower to the Agent and the
Lenders, notwithstanding any right or power of any third party, individually or
in the name of the Borrower, the Agent, the Lenders, or any of them, to assert
any claim or defense as to the invalidity or unenforceability of any such
Obligation, and no such claim or defense shall impair or affect the obligations
of the Guarantor hereunder.

         13. This Guaranty shall be binding upon the Guarantor, its successors
and permitted assigns and inure to the benefit of the successors and assigns of
the Agent and the Lenders. The Guarantor may not assign its rights or
obligations under this Guaranty without the prior written consent of the Agent.
No alteration or waiver of this Guaranty or of any of its terms, provisions or
conditions shall be binding upon the parties against whom enforcement is sought
unless made in writing and signed by an authorized officer of such party.

         14. This is a guaranty of payment and not of collection. In the event
the Agent makes a demand upon the Guarantor under this Guaranty, the Guarantor
shall be held and bound to the Agent directly as debtor in respect of the
payment of the amounts hereby guaranteed. All costs and expenses, including
actual and reasonable attorneys' fees and expenses, incurred by the Agent in
obtaining performance of or collecting payments due under this Guaranty to the
extent permitted by the Loan Agreement, shall be deemed part of the Obligations
guaranteed hereby. Any notice or demand which the Agent may wish to give shall
be served upon the Guarantor in the fashion prescribed for notices in the Loan
Agreement at the address for the Guarantor given on Exhibit A attached hereto
and the notice so sent shall be deemed to be served as set forth in the Loan
Agreement.

         15. The Guarantor expressly represents and acknowledges that any
financial accommodations by the Agent and the Lenders to the Borrower,
including, without limitation, the extension of credit, are and will be of
direct interest, benefit and advantage to the Guarantor.

         16. The Guarantor covenants and agrees that so long as the Commitments
are outstanding or any amount is owing on account of the Obligations (as defined
in the Loan Agreement) or otherwise pursuant to this Guaranty, the Guarantor
shall permit, as provided in the Loan Agreement with respect to the Borrower,
representatives of the Agent and the Lenders to visit and inspect properties of
the Guarantor, inspect the Guarantor's books and records and discuss with the
principal officers of the Guarantor its businesses, assets, liabilities,
financial position, results of operations and business prospects.

         17. The Guarantor hereby represents and warrants that:

         reorganization, moratorium or similar laws affecting the enforcement of
         creditors' rights generally and general equitable principles (whether
         enforcement is sought by proceedings in equity or at law);

                  (d the execution, delivery and performance of this Guaranty
         and the other Loan Documents to which it is a party will not violate

         partner, stockholder or creditor of the Guarantor) is required in
         connection with the execution, delivery, performance, validity or
         enforceability of this Guaranty or (except as provided in such other

         provided to the Agent) and, except with respect to certain state law,

         simple to, or a valid leasehold interest in, all its real property, and
         good title to, or a valid leasehold interest in, all its other

         definition of "Permitted Liens" in Section 1.1 of the Loan Agreement
         (excluding any Liens of the type listed on Schedule P-1 to Loan
         Agreement) and (2) the Liens, if any, of the Guarantor specifically
         listed on such Schedule P-1 of the Loan Agreement; and
