"Existing Agreement"); and

         WHEREAS, the parties have agreed to amend the Existing Agreement so as
to effect certain changes in the Existing Agreement.

         NOW, THEREFORE, the parties hereby agree that effective upon the
Effective Date hereof (as determined pursuant to Paragraph 8 below) the Existing
Agreement is amended as follows:

         1. DEFINITIONS: Section 1.1 of the Existing Agreement is amended to
provide that the following terms shall have the following meanings and, to the
extent that any of the following terms are already defined in the Existing
Agreement, such definitions shall be deemed to be amended and restated by the
following definitions:

         Bank One Excluded Unconsolidated Entity. As of any date, any Person
which is within the definition of Unconsolidated Entity set forth in this
Agreement but which is not within the definition of Unconsolidated Entity set
forth in the Bank One Guaranties.

         Bank One Guaranties. Those certain documents referred to as Guaranty

Illinois, NA relating to the obligations of ceratin of Borrower's Subsidiaries
with respect to Letter of Credit Agreements dated February 17, 1998 relating to
letter of credit facilities in the aggregate amount of $48,809,587, such
Guaranties being dated February 17, 1998 as modified on November 30, 1998,

Each place in the Agreement where there is a reference to BankBoston such
reference shall be

<PAGE>

deemed to be replaced with a reference to Fleet so as to reflect the change in
name from BankBoston, N.A. to Fleet National Bank which became effective on
March 1, 2000.

         2. DELETION OF SECTION 7.23. Section 7.23 of the Agreement is hereby
deleted.

         3. ADDITION OF SECTION 9.7. A new Section 9.7 is hereby added to the
Agreement immediately following Section 9.6 as follows:

                  Section 9.7. Total Liabilities to Total Adjusted Assets
         Excluding Bank One Excluded Unconsolidated Entities . The Borrower will
         not at any time permit Total Liabilities at the end of any fiscal
         quarter to exceed sixty-five percent (65%) of Total Adjusted Assets
         with the computations of this covenant to be done in the same manner as
         in Section 9.3 above except that each place where the definitions of
         EBITDA or Total Liabilities require the computations to include items
         related to Unconsolidated Entities, such computations shall be adjusted
         to exclude all items relating to all Bank One Excluded Unconsolidated
         Entities. Each Compliance Certificate delivered hereunder will include
         an additional schedule in substantially the form attached as Exhibit A
         to this Amendment listing the Bank One Excluded Unconsolidated Entities
         as of the date of such Certificate and setting forth in detail the
         adjustments made with respect to the computations required by this
         Section 9.7. It is the intent of the parties in adding this Section 9.7
         to create a new financial covenant which is equally as stringent as the
         financial covenant (the "Bank One Covenant") set forth in paragraph
         9.2(a) of the Bank One Guaranties, as the Bank One Covenant may be
         amended, and in effect, from time to time. For the avoidance of doubt,
         the parties agree that the Borrower shall not be required to obtain the
         consent of the Lenders or the Agent to any amendment of the Bank One
         Covenant which does not make such covenant more stringent than the
         existing Bank One Covenant, and that if the Bank One Covenant ceases to
         be in effect at any time, whether by reason of amendment to the Bank
         One Guaranties, refinancing of the indebtedness to which the Bank One
         Guaranties relates, or otherwise, then this Section 9.7 shall terminate
         and be of no further force and effect.

         4. UPDATED SCHEDULES TO CREDIT AGREEMENT. The following Schedules to
the Credit Agreement are hereby updated, supplemented or replaced as follows:

               (a) Schedule 1 is replaced by Schedule 1 attached hereto.

               (b) Schedule 1.1 is replaced by Schedule 1.1 attached hereto.

                               WARRANT AGREEMENT

     THIS WARRANT AGREEMENT, dated as of ______________, 2000, by and between
Founders Food & Firkins Ltd., a Minnesota corporation (the "Company"), and
Norwest Bank Minnesota, National Association, as the Warrant Agent (the "Warrant
Agent").

     WHEREAS, the Company proposes to issue up to 1,150,000 units (the "Units"),
each Unit consisting of one share of common stock, $0.01 par value, of the
Company (the "Common Stock") and one redeemable Class A Warrant to purchase one
share of Common Stock (each a "Warrant"), in connection with the Company's
initial public offering (the "Offering") pursuant to the Company's Registration
Statement on Form SB-2, as amended.

     WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent desires so to act, in connection with the
issuance, registration, transfer, exchange and exercise of the Warrants.

     NOW, THEREFORE, the Company and the Warrant Agent hereby agree as follows:

                                   ARTICLE I
                         APPOINTMENT OF WARRANT AGENT;
                        ISSUANCE, FORM AND EXECUTION OF
                              WARRANT CERTIFICATES

     Section 1.1    APPOINTMENT OF WARRANT AGENT.  The Company hereby appoints
the Warrant Agent to act as agent for the Company, and the Warrant Agent hereby
accepts the agency established herein and agrees to perform its agency duties in
accordance with the terms and conditions of this Warrant Agreement.

     Section 1.2    WARRANT CERTIFICATES.  On or about _________________,
2001, the Company shall deliver to the Warrant Agent certificates which the
Company has authorized to represent the Warrants ("Warrant Certificates").
The Warrant Certificates shall be substantially as set forth in Exhibit A
hereto and may have such legends, summaries or endorsements printed thereon
as the Company may deem appropriate and as are not inconsistent with the
provisions of this Warrant Agreement, or as may be required to comply with
any law or with any rule or regulation relating to listing of the Warrants on
the Nasdaq system, including the Nasdaq SmallCap Market, or on any stock
exchange or to conform to usage.  The Warrant Certificates shall be dated
with the date of their issuance.

     Section 1.3    EXECUTION OF WARRANT CERTIFICATES.  The Warrant Certificates
shall be executed on behalf of the Company by a duly authorized officer of the
Company, either manually or by facsimile signature printed thereon.  The Warrant
Certificates shall be manually countersigned by the Warrant Agent and shall not
be valid for any purpose unless countersigned.  Any Warrant Certificate may be
signed on behalf of the Company by the person who at the actual date of the
signing of such Warrant Certificate shall have been a duly authorized officer of
the Company, regardless of whether at the date of issuance of such Warrant
Certificate such person has ceased to be a duly authorized officer of the
Company.

                                   ARTICLE II
                              EXERCISE OF WARRANTS

     Section 2.1    EXERCISE.  Any or all of the Warrants represented by each
Warrant Certificate may be

<PAGE>

exercised by the holder thereof commencing ___________, 2001, but on or
before 5:00 p.m., Minneapolis time, on _______________, 2000 (unless extended
by the Company), by surrender of the Warrant Certificate with the purchase
form, which is printed on the reverse thereof (or a reasonable facsimile
thereof), duly executed by such holder, to the Warrant Agent at its principal
office in South St. Paul, Minnesota.  The purchase form must be accompanied
by payment, in cash or by certified check payable to the Company, in an
amount equal to the product of the number of shares of Common Stock issuable
upon exercise of the Warrant represented by such Warrant Certificate, as
adjusted pursuant to the provisions of Article III hereof, multiplied by the
exercise price of $5.00, as adjusted pursuant to the provisions of Article
III hereof (such price as so adjusted from time to time being herein called
the "Purchase Price"), and such holder shall be entitled to receive such
number of fully paid and nonassessable shares of Common Stock, as so
adjusted, at the time of such exercise.

     Section 2.2    TIME OF EXERCISE.  Each exercise of Warrants shall be
deemed to have been effective immediately prior to the close of business on
the business day on which the Warrant Certificate relating to such Warrant
shall have been surrendered to the Warrant Agent as provided in Section 2.1.
At such time, the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such exercise,
as provided in Section 2.3, shall be deemed to have become the holder or
holders of record thereof.

     Section 2.3    ISSUANCE OF SHARES OF COMMON STOCK; NO FRACTIONAL SHARES.
As soon as practicable after the exercise of any Warrant, and in any event
within 10 days after receipt by the Company of notice of exercise under Section
2.1, the Company, at its expense (including the payment by it of any applicable
issue taxes), will cause to be issued in the name of and delivered to the holder
thereof or as such holder (upon payment by such holder of any applicable
transfer taxes) may direct:

          (a)  a certificate or certificates for the number of fully paid and
     nonassessable shares of Common Stock to which such holder shall be entitled
     upon such exercise plus, in lieu of any fractional share to which such
     holder would otherwise be entitled, an amount in cash equal to such
     fraction multiplied by the then current value of a share of Common Stock,
     such current value to be determined as follows:

               (i)   if the Common Stock shall be listed or admitted to unlisted
          trading privileges on any single national securities exchange, then
          such current value shall be computed on the basis of the last reported
          sale price of the Common Stock on such exchange on the last business
          day prior to the date of the exercise of such Warrant upon which a
          sale shall have been effected; or

               (ii)  if the Common Stock shall not be so listed or admitted to
          unlisted trading privileges and bid and asked prices therefor in the
          over-the-counter market shall be reported by Nasdaq, including the
          Nasdaq SmallCap Market, then such current value shall be computed on
          the basis of the Last Reported Sale Valuation Method or, in the event
          such method is not then used by Nasdaq, the average of the closing bid
          and asked prices on the last business day prior to the date of the
          exercise of such Warrant as so reported; or

               (iii) if the Common Stock shall be listed or admitted to unlisted
          trading privileges on more than one national securities exchange or
          one or more national securities exchanges and in the over-the-counter
          market, then such current value shall, if different as a result of
          calculation under the applicable method(s) described above in this
          Section, be deemed to be the higher number calculated in connection
          therewith; or

               (iv)  if the Common Stock shall not be so listed or admitted to
          unlisted trading

                                       2

<PAGE>

          privileges and such bid and asked prices shall not be so reported,
          then such current value shall be computed on the basis of the book
          value of Common Stock as of the close of business on the last day of
          the month immediately preceding the date upon which such Warrant was
          exercised, as determined by the Company; and

          (b)  in case such exercise includes only part of the Warrant
     represented by the Warrant Certificate, a new Warrant Certificate or
     Warrant Certificates of like tenor calling in the aggregate on the face or
     faces thereof for the number of shares of Common Stock equal (without
     giving effect to any adjustment therein) to the number of such shares
     called for on the face of such Warrant Certificate minus the number of such
     shares designated by the holder for such exercise as provided in Section
     2.1.  Warrants represented by a properly assigned Warrant Certificate may
     be exercised by a next holder without first having a new Warrant
     Certificate issued.

     Section 2.4     EXTENSION OF EXERCISE PERIOD; CHANGE OF EXERCISE PRICE.
The Company may, upon notice given to the Warrant Agent, and without the consent
of the holders of the Warrant Certificates, (a) reduce the Purchase Price during
all or any portion of the originally stated exercise period, (b) extend the
period over which the Warrants are exercisable beyond _______________, 2005,
and (c) increase or decrease the Purchase Price for any period the Warrant
exercise period is extended.  Within a reasonable time prior to the effective
time of such change or extension, the Company shall provide the Warrant Agent
and Warrantholders of record with written notice of any change in the
Purchase Price or extension of the exercise period, as the case may be,
specifying the time to which such exercise period is extended, or the new
Purchase Price and the periods for which such new Purchase Price is in effect.

                                  ARTICLE III
                            ANTIDILUTION PROVISIONS

     Section 3.1     ADJUSTMENT OF PURCHASE PRICE.

          (a)  In the event that:

               (i)   any dividends on any class of stock of the Company payable
          in Common Stock or securities convertible into Common Stock shall be
          paid by the Company;

               (ii)  the Company shall subdivide its then outstanding shares of
          Common Stock into a greater number of shares; or

               (iii) the Company shall combine outstanding shares of Common
          Stock by reclassification or otherwise;

     the Purchase Price in effect immediately prior to such event shall (until
     adjusted again pursuant hereto) be adjusted immediately after such event to
     a price (calculated to the nearest full cent) determined by dividing (A)
     the number of shares of Common Stock outstanding immediately prior to such
     event, multiplied by the then existing Purchase Price, by (B) the total
     number of shares of Common Stock outstanding immediately after such event
     (including the maximum number of shares of Common Stock issuable in respect
     of any securities convertible into Common Stock).  The resulting, quotient
     shall be the adjusted Purchase Price per share.

          (b)  No adjustments of the Purchase Price shall be made if the amount
     of such adjustments shall be less than $0.05 per share, but in such case
     any adjustment that would otherwise be required then to be made shall be
     carried forward and shall be made at the time and together with a
     subsequent

                                       3

<PAGE>

     adjustment which, together with any adjustment or adjustments so carried
     forward, shall amount to not less than $0.05 per share.

     Section 3.2     ADJUSTMENT OF NUMBER OF SHARES PURCHASABLE ON EXERCISE OF
WARRANTS.  Upon each adjustment of the Purchase Price pursuant to Section 3.1
above, the registered holder of each Warrant shall thereafter (until another
such adjustment) be entitled to purchase at the adjusted Purchase Price the
number of shares, calculated to the nearest full share, obtained by multiplying
the number of shares specified in such Warrant (as adjusted as a result of all
adjustments in the Purchase Price in effect prior to such adjustment) by the
Purchase Price in effect prior to such adjustment and dividing the product so
obtained by the adjusted Purchase Price.

     Section 3.3     NOTICE AS TO ADJUSTMENT.  Upon any adjustment of the
Purchase Price and in the number of shares of Common Stock purchasable upon the
exercise of the Warrant, then, and in each such case, the Company shall within
10 days after the effective date of such adjustment give written notice thereof,
by first-class mail, postage prepaid, addressed to each registered Warrantholder
at the address of such Warrantholder as shown on the books of the Company, which
notice shall state the adjusted Purchase Price and the adjusted number of shares
purchasable upon the exercise of the Warrants, setting forth in reasonable
detail the method of calculation and the facts upon which each calculation is
based.

     Section 3.4     EFFECT OF REORGANIZATION, RECLASSIFICATION, MERGER, ETC.
If at any time while any Warrant is outstanding there should be any capital
reorganization or reclassification of the capital stock of the Company (other
than the issuance of any shares of Common Stock in subdivision of outstanding
shares of Common Stock by reclassification or otherwise and other than a
combination of shares provided for in Section 3.1 hereof) or any consolidation
or merger of the Company with another corporation or any sale, conveyance, lease
or other transfer by the Company of all or substantially all of its property to
any other corporation, then the holder of any Warrant shall, during the
remainder of the period such Warrant is exercisable, be entitled to receive,
upon payment of the Purchase Price, the number of shares of stock or other
securities or property of the Company, or of the successor corporation resulting
from such consolidation or merger, or of the corporation in which the property
of the Company has been sold, conveyed, leased or otherwise transferred, as the
case may be, to which the Common Stock (and any other securities and property)
of the Company, deliverable upon the exercise of such Warrant, would have been
entitled upon such capital reorganization, reclassification of capital stock,
consolidation, merger, sale, conveyance, lease or other transfer if such Warrant
had been exercised immediately prior to such capital reorganization,
reclassification of capital stock, consolidation, merger, sale, conveyance,
lease or other transfer; provided that, in any such case, appropriate adjustment
(as determined by the Board of Directors of the Company) shall be made in the
application of the provisions set forth in this Warrant Agreement with respect
to the rights and interests thereafter of the Warrantholders to the end that the
provisions set forth in this Warrant Agreement (including the adjustment of the
Purchase Price and the number of shares issuable upon the exercise of the
Warrants) shall thereafter be applicable, as near as may be reasonably
practicable, in relation to any shares or other property thereafter deliverable
upon the exercise of the Warrants as if the Warrants had been exercised
immediately prior to such capital reorganization, reclassification of capital
stock, consolidation, merger, sale, conveyance, lease or other transfer and the
Warrantholders had carried out the terms of the exchange as provided for by such
capital reorganization, reclassification, consolidation or merger.  The Company
shall not effect any such capital reorganization, consolidation, merger or
transfer unless, upon or prior to the consummation thereof, the successor
corporation or the corporation to which the property of the Company has been
sold, conveyed, leased or otherwise transferred shall assume by written
instrument the obligation to deliver to the holder of each Warrant such shares
of stock, securities, cash or property as, in accordance with the foregoing
provisions, such holder shall be entitled to purchase.

     Section 3.5     PRIOR NOTICE AS TO CERTAIN EVENTS.  In case at any time:

          (a)  the Company shall pay any dividend upon its Common Stock payable
     in stock or make

                                       4

<PAGE>

     any distribution (other than cash dividends) to the holders of its Common
     Stock;

          (b)  the Company shall offer for subscription purposes to the holders
     of its Common Stock any additional shares of stock of any class or any
     other rights;

          (c)  there shall be any capital reorganization or reclassification of
     the capital stock of the Company, or consolidation or merger of the Company
     with, or sale, conveyance, lease or other transfer of all or substantially
     all of its assets to, another corporation; or

          (d)  there shall be a voluntary or involuntary dissolution,
     liquidation or winding up of the Company;

the Company shall give prior written notice, by first-class mail, postage
prepaid, addressed to each registered Warrantholder at the address of such
Warrantholder as shown on the books of the Company, of the date on which (i) the
books of the Company shall close or a record shall be taken for each stock
dividend, distribution or subscription rights or (ii) such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up shall take place, as the case may be.  Such notice shall also specify
the date as of which the holders of the Common Stock of record shall participate
in such dividend, distribution or subscription rights or shall be entitled to
exchange their Common Stock for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up, as the case may be.  Such written notice shall be
given at least 20 days prior to the action in question and not less than 20 days
prior to the date on which the Company's transfer books are closed in respect
thereto.

     Section 3.6   CERTAIN OBLIGATIONS OF THE COMPANY.  The Company will not,
by any voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant Agreement or the Warrant Certificate, but will
at all times in good faith assist in the carrying out of all such terms.
Without limiting the generality of the foregoing, the Company (a) will take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of all Warrants from time to time outstanding, and (b) will
not (i) transfer all or substantially all of its properties and assets to any
other person or entity, (ii) consolidate with or merge into any other entity
where the Company is not the surviving entity, or (iii) permit any other entity
to consolidate with or merge into the Company where the Company is the surviving
entity, where in connection with such consolidation or merger, the Common Stock
then issuable upon the exercise of the Warrant shall be changed into or
exchanged for shares or other securities or property of any other entity unless,
in any such case, the other entity acquiring such properties and assets,
continuing or surviving after such consolidation or merger or issuing or
distributing such shares or other securities or property, as the case may be,
shall expressly assume in writing and be bound by all the terms of this Warrant
Agreement and the Warrant Certificates.

     Section 3.7    RESERVATION AND LISTING OF COMMON STOCK.  The Company will
at all times reserve a sufficient number of shares of Common Stock to provide
for the issuance of the same upon the exercise of all outstanding Warrants.  All
such shares shall be authorized and, when issued upon such exercise, shall be
validly issued, fully paid and nonassessable.  Upon the exercise of any of the
Warrants, the Company, at its expense, will list on the Nasdaq system, including
the Nasdaq SmallCap Market, if applicable, and on each national securities
exchange on which any Common Stock may be listed, subject to official notice of
issuance, and will use its best efforts to maintain such listing of, the shares
of Common Stock issued upon the exercise of any Warrant.

     Section 3.8    REGISTRATION OR EXEMPTION FOR COMMON STOCK.  The Company
will use its best efforts to (a) maintain the effectiveness of a current
prospectus covering the shares of Common Stock underlying the Class A Warrants
pursuant to the Securities Act of 1933, as amended (the "Securities Act"), and
(b) maintain the exemptions or qualifications of such Common Stock under the
securities laws of the states in which the Company

                                       5

<PAGE>

initially qualifies the Units for sale in the Offering.  The Warrant Agent
shall have no responsibility for the maintenance of such exemptions or
qualifications or for liabilities arising from the exercise or attempted
exercise of Warrants in jurisdictions where exemptions or qualifications have
not been maintained or are otherwise unavailable.  Shares of Common Stock
will not be issued to persons desiring to exercise the Warrants if, at the
time of exercise, a registration statement is not effective under the
Securities Act or the Common Stock underlying the Warrants is not qualified
or exempt from qualification in the state where the holders of the Warrants
reside.

                                   ARTICLE IV
                             REDEMPTION OF WARRANTS

     Section 4.1     REDEMPTION PRICE.  The Warrants may be redeemed at the
option of the Company at any time once they become exercisable, upon notice
as set forth in Section 4.2, at the redemption price equal to $0.01 per
warrant, provided that the closing bid price of the Common Stock on the
Nasdaq system exceeds $6.25 per share (such price subject to adjustment from
time to time in the same manner as the Purchase Price pursuant to the
provisions of Article III hereof) for any 45 consecutive trading days prior
to the date such notice of redemption is given.

     Section 4.2     NOTICE OF REDEMPTION.  In the case of any redemption of
Warrants, the Company or, at its request, the Warrant Agent in the name of and
at the expense of the Company, shall give notice of such redemption to the
holders of the Warrants to be redeemed as hereinafter provided in this Section
4.2.  Notices of redemption to the holders of Warrants shall be given by mailing
by first-class mail a notice of such redemption not less than 20 days prior to
the date fixed for redemption.  Any notice which is given in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the Warrantholder receives notice.  In any case, failure to duly give such
notice to the holder of any Warrant Certificate shall not affect the validity of
the proceedings for the redemption of the Warrants represented by any other
Warrant Certificate.  Each such notice shall specify the date fixed for
redemption, the place of redemption and the redemption price of $0.01 at which
each Warrant is to be redeemed, and shall state that payment of the redemption
price of the Warrants will be made upon surrender of the Warrants at such place
of redemption, and that if not exercised by the close of business on the date
fixed for redemption, the exercise rights of the Warrants identified for
redemption shall expire unless extended by the Company.  Such notice shall also
state the current Purchase Price and the date on which the right to exercise the
Warrants will expire unless extended by the Company.

     Section 4.3     PAYMENT OF WARRANTS ON REDEMPTION; DEPOSIT OF REDEMPTION
PRICE.  If notice of redemption shall have been given as provided in Section
4.2, the redemption price of $0.01 per Warrant shall, unless the Warrant is
theretofore exercised pursuant to the terms hereof, become due and payable on
the date and at the place stated in such notice.  On and after such date of
redemption, provided that cash sufficient for the redemption thereof shall then
be deposited by the Company with the Warrant Agent for that purpose, the
exercise rights of the Warrants identified for redemption shall expire.  On
presentation and surrender of Warrant Certificates at such place of payment
specified in such notice, the Warrant identified for redemption shall be paid
and redeemed at the redemption price of $0.01 per Warrant.  Prior to the date
fixed for redemption, the Company shall deposit with the Warrant Agent an amount
of money sufficient to pay the redemption price of all the Warrants identified
for redemption.  Any monies which shall have been deposited with the Warrant
Agent for redemption of Warrants and which are not required for that purpose by
reason of exercise of Warrants shall be repaid to the Company upon delivery to
the Warrant Agent of evidence satisfactory to it of such exercise.

                                   ARTICLE V
                      CERTAIN OTHER PROVISIONS RELATING TO
                   RIGHTS OF HOLDERS OF WARRANT CERTIFICATES

     Section 5.1     NO RIGHTS OF SHAREHOLDERS.  The Warrant Certificates shall
be issued in registered form only.  No Warrant Certificate shall entitle the
holder thereof to any of the rights of a holder of shares of Common Stock of the
Company, including, without limitation, the right to vote, to receive dividends
and other distributions, or to receive any notice of, or to attend meetings of
holders of Common Stock or any other proceeding of the Company.

     Section 5.2     LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT
CERTIFICATES.  Upon receipt by the Warrant Agent of evidence reasonably
satisfactory to the Warrant Agent of the loss, theft, destruction or
mutilation of any Warrant Certificate, and (a) in the case of such loss,
theft, or destruction, upon delivery to the Warrant Agent of an indemnity
bond in form and amount, and issued by a bonding company, reasonably
satisfactory to the Company, or (b) in the case of any such mutilation, upon
surrender to and cancellation by the Warrant Agent of such Warrant
Certificate, the Company at its expense will execute and cause the Warrant
Agent to countersign and deliver, in lieu thereof, a new Warrant Certificate
of like tenor.

     Section 5.3     TRANSFER AGENT; CANCELLATION OF WARRANT CERTIFICATES;
UNEXERCISED WARRANTS.  Norwest Bank Minnesota, National Association (and any
successor), as transfer agent of the Common Stock (the "Transfer Agent"), is
hereby irrevocably authorized and directed at all times to reserve such number
of authorized and unissued shares of Common Stock as shall be sufficient to
permit the exercise in full of all Warrants from time to time outstanding.  The
Company will keep a copy of this Warrant Agreement on file with the Transfer
Agent.  The Warrant Agent, and any successor thereto, is hereby irrevocably
authorized to requisition from time to time from the Transfer Agent certificates
for shares of Common Stock required for exercise of Warrants.  The Company will
supply the Transfer Agent with duly executed certificates for shares of Common
Stock for such purpose and will make available any cash required in settlement
of fractional share interests.  All Warrant Certificates surrendered upon the
exercise or redemption of Warrants shall be canceled by the Warrant Agent and
shall thereafter be delivered to the Company.  Such canceled Warrant
Certificates, with the purchase form on the reverse thereof duly completed and
signed, shall constitute conclusive evidence as between the parties hereto of
the numbers of shares of Common Stock which shall have been issued upon
exercises of Warrants.  Promptly after the last day on which the Warrants are
exercisable (set forth in Section 2.1 above), the Warrant Agent shall certify to
the Company the aggregate number of Warrants then outstanding and unexercised.
No shares of Common Stock shall be subject to reservation with respect to
Warrants not exercised prior to the time and date identified in Section 2.1
above as the last time and date at which Warrants may be exercised.

                                   ARTICLE VI
                 TRANSFER AND EXCHANGE OF WARRANT CERTIFICATES

     Section 6.1     WARRANT REGISTER; TRANSFER OR EXCHANGE OF WARRANT
CERTIFICATES.  The Warrant Agent shall cause to be kept at the principal office
of the Warrant Agent a register (the "Warrant Register") in which, subject to
such reasonable regulations as the Company may prescribe, provisions shall be
made for the registration of transfers and exchanges of Warrant Certificates.
Upon surrender for transfer or exchange of any Warrant Certificate, properly
endorsed, to the Warrant Agent, the Warrant Agent at the Company's expense will
issue and deliver to or upon the order of the holder thereof a new Warrant
Certificate of like tenor, in the name of such holder or as such holder (upon
payment by such holder of any applicable transfer taxes) may direct, calling in
the aggregate on the face thereof for the number of shares of Common Stock
called for on the face of the Warrant Certificate so surrendered.  Any Warrant
Certificate surrendered for transfer or exchange shall be canceled by the
Warrant Agent and shall thereafter be delivered to the Company.

     Section 6.2    IDENTITY OF WARRANTHOLDERS.  Until a Warrant Certificate is
transferred in the Warrant Register, the Company and the Warrant Agent may treat
the person in whose name the Warrant Certificate is registered as the absolute
owner thereof and of the Warrants represented thereby for all purposes,
notwithstanding any notice to the contrary, except that, if and when any Warrant
Certificate is properly assigned in blank, the Company and the Warrant Agent may
(but shall not be obligated to) treat the bearer thereof as the absolute owner
of the Warrant Certificate and of the Warrant represented thereby for all
purposes, notwithstanding any notice to the contrary.

                                  ARTICLE VII
                          CONCERNING THE WARRANT AGENT

     Section 7.1     TAXES.  The Company will, from time to time, promptly
pay to the Warrant Agent, or make provision satisfactory to the Warrant Agent
for the payment of all taxes and charges that may be imposed by the United
States or any state upon the Company or the Warrant Agent upon the transfer
or delivery of shares of Common Stock upon the exercise of Warrants, but the
Company shall not be obligated to pay any tax imposed in connection with any
transfer involved in the delivery of a certificate for shares of Common Stock
in any name other than that of the registered holder of the Warrant
Certificate surrendered in connection with the purchase thereof.

     Section 7.2     REPLACEMENT OF WARRANT AGENT IN CERTAIN CIRCUMSTANCES.

          (a)  The Warrant Agent may resign its duties and be discharged from
     all further duties and liabilities hereunder after giving 20 days' written
     notice to the Company (except that such shorter notice may be given if
     approved by the Company).  The Company may discharge the Warrant Agent at
     any time with or without reason, effective upon 20 days' written notice to
     the Warrant Agent (except that such shorter notice may be given if approved
     by the Warrant Agent).  If the office of Warrant Agent becomes vacant by
     resignation, discharge, incapacity to act or otherwise, the Company shall
     appoint a new Warrant Agent.  If the Company shall fail to make such
     appointment within a period of 20 days after it has been notified in
     writing of such resignation or incapacity by the resigning or incapacitated
     Warrant Agent or by the holder of a Warrant Certificate, then the holder of
     any Warrant Certificate may apply to any court of competent jurisdiction
     for the appointment of a new Warrant Agent.  Any new Warrant Agent, whether
     appointed by the Company or by such a court, shall be a corporation
     organized and doing business under the laws of the United States or of the
     state of its incorporation and authorized under such laws to exercise
     corporate trust powers and subject to supervision or examination by federal
     or state authority.  Furthermore, such new Warrant Agent shall be of good
     standing.  Any new Warrant Agent appointed hereunder shall execute,
     acknowledge and deliver to the Company an instrument accepting such
     appointment hereunder and thereupon such new Warrant Agent without any
     further act or deed shall become vested with all the rights, powers, duties
     and responsibilities of the Warrant Agent hereunder with like effect as if
     it had been named herein as the Warrant Agent, but if for any reason it
     becomes necessary or expedient to have the former Warrant Agent execute and
     deliver any further assurance, conveyance, act or deed, the same shall be
     done and shall be legally and validly executed and delivered by the former
     Warrant Agent.  Not later than the effective date of any such appointment
     the Company shall file notice thereof with the former Warrant Agent.  The
     Company shall promptly give notice of any such appointment to the holders
     of the Warrant Certificates by mail to their addresses as shown in the
     Warrant Register.  Failure to file or give such notice, or any defect
     therein, shall not affect the legality or validity of the appointment of
     the successor Warrant Agent.

          (b)  Any company into which the Warrant Agent or any new Warrant Agent
     may be merged or converted or with which it may be consolidated or any
     company resulting from any merger, conversion or consolidation to which the
     Warrant Agent or any new Warrant Agent shall be a party, shall be the

                                       8
<PAGE>

     successor Warrant Agent under this Warrant Agreement without any further
     act; provided that if such company would not be eligible for appointment as
     a successor Warrant Agent under the provisions of paragraph (a) of this
     Section 7.2 the Company shall forthwith appoint a new Warrant Agent in
     accordance with such provisions.  Any such successor Warrant Agent may
     adopt the prior countersignature of any predecessor Warrant Agent and
     deliver Warrant Certificates countersigned and not delivered by such
     predecessor Warrant Agent or may countersign Warrant Certificates either in
     the name of any predecessor Warrant Agent or the name of the successor
     Warrant Agent.

     Section 7.3     REMUNERATION OF WARRANT AGENT.  The Company will pay the
Warrant Agent reasonable remuneration in accordance with the Warrant Agent's
Warrant Exchange for Common Stock Fee Schedule, as amended from time to time,
for its services as Warrant Agent hereunder and will reimburse the Warrant Agent
upon demand for all expenditures that the Warrant Agent may reasonably incur in
the execution of its duties hereunder.

     Section 7.4     FURTHER ASSURANCES.  The Company will perform, exercise,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all acts, instruments and assurances as reasonably may be required by
the Warrant Agent for the carrying out or performing by the Warrant Agent of the
provisions of this Warrant Agreement.

     Section 7.5     LIMITATIONS ON LIABILITIES OF THE WARRANT AGENT.

          (a)  The Warrant Agent may consult with legal counsel (who may be
     legal counsel for the Company), and the opinion of such counsel shall be
     full and complete authorization and protection of the Warrant Agent as to
     any action taken or omitted by it in good faith and in accordance with such
     opinion.

          (b)  Whenever, in the performance of its duties under this Warrant
     Agreement, the Warrant Agent shall deem it necessary or desirable that any
     matter be provided or established, or that any instructions with respect to
     the performance of its duties hereunder be given, by the Company prior to
     taking or suffering any action hereunder, such matter (unless other
     evidence in respect thereof be herein specifically prescribed) may be
     deemed to be conclusively proved and established, or such instructions may
     be given, by a certificate or instrument signed by an officer of the
     Company and delivered to the Warrant Agent; and such certificate or
     instrument shall be full authorization to the Warrant Agent for any action
     taken or suffered in good faith by it under the provisions of this Warrant
     Agreement in reliance upon such certificate or instrument; provided,
     however, that in its discretion the Warrant Agent may in lieu thereof
     accept other evidence of such matter or may require such further or
     additional evidence as it may deem reasonable.

          (c)  The Warrant Agent shall be liable hereunder only for its own
     negligence or willful misconduct.  The Warrant Agent shall act hereunder
     solely as agent, and its duties shall be determined solely by the
     provisions hereof.  The Company agrees to indemnify the Warrant Agent and
     save it harmless against any and all liabilities, including judgments,
     costs and counsel fees, for anything done or omitted by the Warrant Agent
     in the execution of this Warrant Agreement except as a result of the
     Warrant Agent's negligence or willful misconduct.

          (d)  The Warrant Agent shall not be liable for or by any reason of any
     of the statements of fact or recitals contained in this Warrant Agreement
     or in the Warrant Certificates (except its countersignature thereof) or be
     required to verify the same, but rather all such statements and recitals
     are and shall be deemed to have been made by the Company only.

          (e)  The Warrant Agent shall not be under any responsibility in
     respect to the validity or execution of any Warrant Certificate (except its
     countersignature thereof); nor shall it be responsible for

                                       9
<PAGE>

     any breach by the Company of any covenant or condition contained in this
     Warrant Agreement or in any Warrant Certificate; nor shall it be
     responsible for the making of any adjustment in the Purchase Price, or
     number of shares issuable upon exercise of the Warrant Certificates or
     responsible for the manner, method or amount of any such adjustment or the
     facts that would require any such adjustment; nor shall it by any act
     hereunder be deemed to make any representation or warranty as to the
     authorization or reservation of any shares of Common Stock to be issued
     pursuant to this Warrant Agreement or any Warrant Certificate or as to
     whether any shares of Common Stock or other securities are or will be duly
     authorized and validly issued and fully paid and nonassessable.

     Section 7.6   AMENDMENT AND MODIFICATION.  The Warrant Agent may, without
the consent or concurrence of the holders of the Warrant Certificates, by
supplemental agreement or otherwise, join with the Company in making any changes
or corrections in this Warrant Agreement (a) which they shall have been advised
by counsel are required to cure any ambiguity or to correct any defective or
inconsistent provision or clerical omission or mistake or manifest error herein
contained, (b) which add to the obligations of the Company in this Warrant
Agreement further obligations thereafter to be observed by it, or surrender any
right or power reserved to or conferred upon the Company in this Warrant
Agreement, or (c) which do not or will not adversely affect, alter or change the
rights, privileges or immunities of the holders of Warrant Certificates not
provided for under this Warrant Agreement; provided, however, that any term of
this Warrant Agreement or any Warrant Certificate may be changed, waived,
discharged or terminated by an instrument in writing signed by each party
against which enforcement of such change, waiver, discharge or termination is
sought, or by which the same is to be performed or observed.

                                  ARTICLE VIII

construed and enforced in accordance with and governed by the laws of such
state, without giving effect to such state's choice of law rules.

     Section 8.4    NO BENEFITS CONFERRED.  Nothing in this Warrant Agreement
expressed and nothing that may be implied from any of the provisions hereof is
intended, or shall be construed, to confer upon, or give to, any person or

             INCORPORATED UNDER THE LAWS OF THE STATE OF MINNESOTA

     THIS CERTIFIES that ____________________________________________________
or assigns, is the owner of the number of Warrants set forth above, each of
which represents the right to purchase from Founders Food & Firkins Ltd., a
Minnesota corporation (the "Company"), at any time commencing ____________,
2001, but on or before 5:00 p.m., Minneapolis time, on ____________, 2005,
upon compliance with and subject to the conditions set forth herein and in
the Warrant Agreement hereinafter referred to, one share (subject to
adjustments referred to below) of common stock of the Company (the "Shares"),
by surrendering this Warrant Certificate, with the purchase form on the
reserve side duly executed, at the principal office of Norwest Bank
Minnesota, National Association, or its successor, as warrant agent (the
"Warrant Agent"), and by paying, in full, in cash or by certified check
payable to the order of the Company, the purchase price of $5.00 per Share,
subject to adjustment.

     Upon any exercise of less than all the Warrants evidenced by this Warrant
Certificate, there shall be issued to the holder a new Warrant Certificate in
respect of the Warrants as to which this Warrant Certificate was not exercised.

     Upon the surrender for transfer or exchange hereof, properly endorsed,
to the Warrant Agent, the Warrant Agent (at the Company's expense) will issue
and deliver to the order of the holder hereof, a new Warrant Certificate or
Warrant Certificates of like tenor, in the name of such holder or as such
holder (upon payment by such holder of any applicable transfer taxes) may
direct, calling in the aggregate on the face thereof for the number of Shares
called for on the face hereof.

     The Warrant Certificates are issued only as registered Warrant
Certificates.  Until this Warrant Certificate is transferred in the Warrant
Register, the Company and the Warrant Agent may treat the person in whose name
this Warrant Certificate is registered as the absolute owner hereof and of the
Warrants represented hereby for all purposes, notwithstanding any notice to the
contrary.

     This Warrant Certificate is issued under the Warrant Agreement dated as of
___________, 2000, between the Company and the Warrant Agent and is subject to
the terms and provisions contained in said Warrant Agreement, to all of which
terms and provisions the registered holder of this Warrant Certificate consents
by acceptance hereof.  Copies of said Warrant Agreement are on file at the
principal office of the Warrant Agent in South St. Paul, Minnesota, and may be
obtained by written request to the Warrant Agent.

     The number of Shares receivable upon the exercise of the Warrants
represented by this Warrant Certificate and the purchase price per share are
subject to adjustment upon the happening of certain events specified in the
Warrant Agreement (which provisions are contained in Article III of the
Warrant Agreement and are hereby incorporated by reference).

     No fractional Shares will be issued upon the exercise of Warrants.  As
to any final fraction of a share which a holder of Warrants exercised in the
same transaction would otherwise be entitled to purchase on such exercise,
the Company shall pay a cash adjustment in lieu of any fractional Share
determined as provided in the Warrant Agreement.

     The Warrants may be redeemed by the Company at any time once they become
exercisable, upon notice of such redemption as set forth below, at the
redemption price equal to $0.01 per warrant, provided that the closing bid
price of the Shares on the Nasdaq system exceeds $6.25 per share (subject to
adjustment as provided in the Warrant Agreement) for any 45 consecutive
trading days prior to the date such notice of redemption is given.  Notice of
redemption shall be mailed not less than 20 days prior to the date fixed for
redemption to the holders of Warrants at their last registered addresses.  If
notice of redemption shall have been given as provided in the Warrant
Agreement and cash sufficient for the redemption to be deposited by the
Company for that purpose, the exercise rights of the Warrants identified for
redemption shall expire at the close of business on such date of redemption
unless extended by the Company.

     This Warrant Certificate shall not entitle the holder hereof to any of
the rights of a holder of Shares, including, without limitation, the right to
vote, to receive dividends and other distributions, to exercise any
preemptive right, or to receive any notice of or to attend meetings of
holders of Shares or any other proceedings of the Company.

     Shares may not be issued to holder upon exercise of this Warrant if, at
the time of exercise, a registration statement with respect to such Shares is
not effective under the Securities Act or if the Shares underlying the
Warrant are not qualified or exempt from qualification in the state wherein
the holder of the Warrant resides.

     This Warrant Certificate shall be void and the Warrants and any rights
represented hereby shall cease unless exercised on or before 5:00 p.m.,
Minneapolis time, on _______________, unless extended by the Company.

     This Warrant Certificate shall not be valid for any purpose until it shall
have been countersigned by the Warrant Agent.

     WITNESS the facsimile signatures of the Company's duly authorized officers.
