GUARANTY

In order to induce JOSEPH R. VICENTE, an individual (the “Lender”), to extend
credit to CBA PROFESSIONAL SERVICES, INC., a Florida corporation (the “Maker”)
and a wholly-owned subsidiary of the undersigned, including that evidenced by
the foregoing Promissory Note (the “Note”), the undersigned hereby covenants and
agrees with the Lender as follows:

3

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

1.

The undersigned, as joint and several obligor with the Borrower, hereby
irrevocably and unconditionally guarantees the payment when due to the Lender of
any and all obligations, indebtedness and liabilities of the Borrower to the
Lender, whether now existing or hereafter arising, whether absolute or
contingent, and whether or not evidenced by a written instrument (collectively,
the “Obligations”), including without limitation those evidenced by the Note.
This is a guaranty of payment, rather than a guaranty of collection.

2.

If the Borrower shall default in the payment of any or all of the Obligations
when due to the Lender, then the undersigned shall pay to the Lender within five
(5) days after demand therefor shall have been made, in immediately available
funds, the full amount of the Obligations then due (by acceleration or
otherwise). Except as otherwise provided in the immediately preceding sentence
of this paragraph, the undersigned hereby waives notice of acceptance of this
Guaranty and notice of any and all of the Obligations to which it may apply, and
hereby waives presentment, demand of payment, protest, notice of dishonor or
nonpayment of any and all of the Obligations, suit or the taking of other action
by the Lender against, and any other notice to, any party liable thereon
(including the undersigned).

3.

The Lender may at any time and from time to time without the consent of, or
notice to, the undersigned, without incurring responsibility to the undersigned
and without impairing or releasing the obligations of the undersigned hereunder,
upon or without any terms or conditions and in whole or in part (i) change the
manner, place or terms or payment of, and/or change or extend the time of
payment of, renew or alter, any or all of the Obligations, any security there
for, or any liability incurred directly or indirectly in respect thereof, and
this Guaranty shall apply to all of the Obligations as so changed, extended,
renewed or altered; (ii) exercise or refrain from exercising any right against
the Borrower or others (including the undersigned) or otherwise act or refrain
from acting; (iii) settle or compromise any or all of the Obligations, any
security there for or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and may subordinate the
payment of all or any part thereof to the payment of any liability (whether due
or not) of the Borrower to creditors of the Borrower other than the Lender and
the undersigned; (iv) apply any sums by whomsoever paid or howsoever realized,
other than payments by the undersigned of any or all of the Obligations, to any
liability or liabilities of the Borrower to the Lender regardless of what
liability or liabilities of the Borrower remain unpaid; and/or (v) consent to or
waive any breach of, or any act, omission or default under, any or all of the
Obligations.

4.

No invalidity, irregularity or lack of enforceability of any or all of the
Obligations or of any security therefor shall affect, impair or be a defense to
this Guaranty, and this Guaranty constitutes a primary obligation of the
undersigned.

5.

If and to the extent that the undersigned makes any payment to the Lender or to
any other person pursuant to or in respect of this Guaranty, any claim which the
undersigned may have against the Borrower by reason thereof shall be subject and
subordinate to the prior payment in full of all of the Obligations.

4

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

6.

This Guaranty is a continuing one and all Obligations to which it applies or may
apply under the terms hereof shall be conclusively presumed to have been created
in reliance hereon. No delay on the part of the Lender in exercising any of its
options, powers or rights, or partial or single exercise thereof, shall
constitute a waiver thereof. No waiver of any of his rights hereunder, and no
modification or amendment of this Guaranty, shall be deemed to be made by the
Lender unless the same shall be in writing, duly signed on behalf of the Lender,
and each such waiver (if any) shall apply only with respect to the specific
instance involved and shall in no way impair the rights of the Lender or the
obligations of the undersigned to the Lender in any other respect at any other
time. This Guaranty and the rights and obligations of the Lender and of the
undersigned hereunder shall be governed by, and construed and interpreted in
accordance with, the laws of the State of Florida, without giving effect to the
principles of conflicts of laws thereof. This Guaranty is binding upon the
undersigned and its successors and assigns and shall inure to the benefit of the
Lender and his heirs, personal representatives, successors and assigns,
including without limitation any other holder at any time of any or all of the
Obligations, including without limitation the foregoing Note.

IN WITNESS WHEREOF, the undersigned, by and through its undersigned officer
thereunto duly authorized, has executed and delivered this Guaranty as of
January 17, 2005.
