P R O V I S I O N S :

NOW, THEREFORE, in consideration of the Consent provided by Boston Brewing
and other good and valuable consideration, Genesee hereby agrees in favor of
Boston Brewing as follows:

1. Performance Guaranty.

(a) Subject to the terms and conditions herein, Genesee hereby 
guarantees the due, punctual and faithful performance by Monroe Brewing of its
obligations, duties, covenants and responsibilities under the Production
Agreement that arise after the closing under the Purchase Agreement based on
facts occurring subsequent thereto. Genesee hereby specifically further agrees
that in the event Monroe Brewing, for any reason, is obligated to perform under
the Production

Agreement and it fails to do so in accordance with the terms thereof, Genesee
will, upon written notice from Boston Brewing, become liable to Boston Brewing
for any sum or sums Monroe Brewing has to pay Boston Brewing under the terms of
the Production Agreement for failure to perform or pay, subject to the terms and
conditions contained therein or any defenses thereto which either Monroe Brewing
may have or which Genesee may have.

(b) Notwithstanding anything herein to the contrary, Genesee's
obligations under this Guaranty and the Production Agreement shall terminate and
be of no further force or effect upon the expiration of 1,095 days after the
"Closing Date" (as defined in the Purchase Agreement) (the "Termination Date"),
provided that any claims made in writing by Boston Brewing against Genesee
hereunder prior to the Termination Date and remaining unresolved or outstanding
as of such date shall survive until the earlier to occur of the payment or the
final resolution and satisfaction of such claims to the extent and subject to
the terms and conditions herein. The period between the Closing Date and the
Termination Date is referred to herein as the "Guaranty Period."

2. Net Worth Maintenance. 

(a) During the Guaranty Period, Genesee will maintain a Liquid Net Worth
(defined for this purpose as the excess of (i) unencumbered (1) cash and
currency on hand and on deposit, demand deposits and checks held, (2)
short-term, highly liquid investments that are readily convertible to known
amounts of cash plus (3) marketable securities over (ii) total liabilities, each

(b) After the Guaranty Period, Genesee will maintain a Liquid Net Worth 
in an amount that, in the aggregate, is not less than the amount of any claims
made by Boston Brewing in accordance with Section 1 hereof that remain
unresolved.

3. Enforcement / Notice.

(a) If Monroe Brewing fails to perform any of its duties under the
Production Agreement guaranteed hereby, then Boston Brewing may proceed directly
to make a claim against Genesee to be paid by Genesee without necessity of any
suit or proceeding by Boston Brewing against Monroe Brewing. Genesee shall be
entitled to assert any defenses or claims that Genesee or Monroe Brewing may
have under the Production Agreement or otherwise against any claim made by
Boston Brewing and does not otherwise waive any defenses whatsoever to its
obligations hereunder or under the Production Agreement. Anytime, with or
without consideration or notice, Boston Brewing may waive enforcement of the
terms, conditions and provisions of this Guaranty with respect to any breach or
default by Monroe Brewing, and such waiver will not diminish or

otherwise affect Monroe Brewing's obligations to Boston Brewing under the
Production Agreement. Genesee agrees that in the event any of the foregoing
provisions are found to be unenforceable, that portion so found will in no way
affect the purpose and intent of the remaining provisions, and to that extent
those provisions will remain binding upon the parties.

(b) Any claim, notice or other communication under this Guaranty shall
be in writing, and shall be deemed duly given when delivered personally or by
facsimile, or four days after being mailed by registered mail, return receipt
requested, or by documented over-night delivery to a party at the following

such payment to enforce any remedy which Boston Brewing may have against Monroe
Brewing therefor.

Genesee's continuing liability hereunder, by its acceptance hereof, Boston
Brewing hereby acknowledges that Monroe Brewing has agreed with Genesee that, so
long as Genesee has any liability to Boston Brewing, it shall not agree to amend
