                           AGREEMENT AMONG GUARANTORS


         This Agreement (the "Agreement") is made and entered into as of January
22, 1999, by and among Stephen D. King ("King"), Jerry L. Ruyan ("Ruyan") Andrew
Green ("Green") (each also a "Guarantor"), and Cafe Odyssey, Inc., a Minnesota
corporation (the "Company").

                                  INTRODUCTION

         A. The Company is a party to a Loan Agreement dated October 9, 1996
with PNC Bank, Ohio, National Association, as amended (the "PNC Loan
Agreement").

         B. As of September 23, 1998, the Company entered into a Revolving
Promissory Note (the "Note") with The Provident Bank, an Ohio banking
corporation ("Provident") in order to retire the Company's indebtedness under
the PNC Loan Agreement and obtain additional financing (collectively, the
"Provident Financing"). The Provident Financing consists of a first tranche in
the principal amount of $1,000,000 (the "First Tranche") and a subsequent or
concurrent second tranche in a principal amount of up to $2,000,000 (the "Second
Tranche").

         C. In connection with the Second Tranche, Provident required guarantors
to execute Several Limited Guarantees (each, a "Second Tranche Guaranty") of the
Note and pledge certain assets to Provident. King and Ruyan have each executed a
$500,000 Second Tranche Guaranty, Green is executing a $500,000 Second Tranche
Guaranty concurrently herewith and Green will execute another $500,000 Second
Tranche Guaranty on or before March 10, 1999.

         D. In consideration of Green's Guarantees and pledge of collateral, the
Company wishes to issue to Green a warrant to purchase shares of the Common
Stock, $.01 par value (the "Common Stock"), of the Company (individually a
"Warrant" and collectively the "Warrants"). Green and the Company also desire to
provide for the issuance of additional Warrants and payment of cash to Green if
the Company does not repay the Note on a timely basis.

         E. The Company has already undertaken to issue warrants and pay cash to
King and Ruyan pursuant to that certain Agreement Among Guarantors dated
November 16, 1998, to which the Company, King and Ruyan are parties.

         F. The Guarantors desire to remedy the inequities that may otherwise
result from enforcement of any of the Guarantees through an agreement providing
for appropriate indemnification and contribution rights and obligations among
the Guarantors.

        NOW, THEREFORE, in consideration of the foregoing, and for other good
and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Guarantors hereto agree as follows:

        1.       Guarantees and Collateral. On or before the date hereof, Green
has executed a $500,000 Second Tranche Guaranty and a Pledge and Security
Agreement (a "Pledge") in connection therewith. Green agrees to execute another
$500,000 Second Tranche Guaranty on or before March 10, 1999.

        2.       Issuance of Warrants upon Execution of Second Tranche
Guarantees and Pledge. In connection with the Second Tranche, the Company shall
issue to Green a Warrant to purchase 200,000 shares of Common Stock in the form
attached as Exhibit A hereto upon his execution of his first $500,000 Second
Tranche Guaranty and a second Warrant to purchase 200,000 shares of Common Stock
upon his execution of his second $500,000 Second Tranche Guaranty.

        3.       Issuance of Warrants and Payment of Cash upon Company's Failure
to Timely Repay the Note. If the Company does not repay the Second Tranche of
the Note in full on or before September 30, 1999 (the "Due Date"), and assuming
Green has executed two $500,000 Second Tranche Guarantees:

                 (a) the Company shall issue to Green a Warrant to purchase
40,000 shares of Common Stock in the form attached as Exhibit A hereto.
Thereafter, for so long as any amount due under the Note shall remain unpaid, on
each monthly anniversary of the Due Date, the Company shall issue to Green a
Warrant to purchase 40,000 shares of Common Stock in the form attached as
Exhibit A hereto; and

                 (b) the Company shall pay Green $10,000 on the Due Date,
$20,000 on the first monthly anniversary of the Due Date, $30,000 on the second
monthly anniversary of the Due Date and $40,000 on the third and each subsequent
monthly anniversary of the Due Date until the Note is paid in full.

        4.       Company Liability for Payments on Guarantees; Green's Priority.
Upon Green's payment of any loss, claim, damage, expense or liability arising
under the Note (each a "Claim"), the Company shall be obligated to immediately
reimburse Green for the full amount of such payment. In order to secure its
obligation pursuant to this Section, the Company shall execute a Security
Agreement in the form attached as Exhibit B hereto. The parties agree that the
Company's liability to Green under this Section 4 shall have priority over any
obligation of the Company to King or Ruyan under the Agreement Among Guarantors.

        5.       Draws under Provident Financing. The Chairman of the Board of
the Company, in his or her sole discretion, shall determine the amount and
timing of draws to be made under the Provident Financing, subject to the
aggregate amounts set forth in paragraph B. above.

        6.       Amendment, Waiver and Third Party Beneficiaries. This Agreement
may not be amended orally, but only by an instrument in writing signed by all of
the Guarantors who are parties hereto. No delay or failure on the part of any
Guarantor to exercise any power or right hereunder shall operate as a waiver
thereof, nor as an acquiescence in any default, nor shall any single or partial
exercise of any power or right preclude any other or further exercise thereof,
or the exercise of any other power or right. The Guarantors acknowledge and
agree that this Agreement is not intended to create any third party beneficiary
rights.

        7.       Partial Invalidity. If any provision or application of this
Agreement is held unlawful or unenforceable in any respect, such illegality or
unenforceability shall not effect other provisions or applications which can be
given effect, and this Agreement shall be construed as if the lawful and
unenforceable provision or application had never been contained hereby or
prescribed hereby.

        8.       Governing Law, Submission to Jurisdiction. All questions
concerning the construction, validity and interpretation of this Agreement will
be governed by and construed in accordance with the internal law, and not the
law of conflicts of law, of the State of Minnesota. Each of the parties hereto
consents and agrees to the jurisdiction of any state court sitting in the City
of Minneapolis, State of Minnesota, or any federal court sitting in the city of
Minneapolis, State of Minnesota, and waives any objection based on venue or
forum non conveniens with respect to any action instituted therein.

        9.       Assignment. This Agreement shall be binding upon the Guarantors
and their successors and assigns and shall inure to the benefit of the
Guarantors and their successors and assigns.

        10.      Integration. This Agreement contains the full, final and
exclusive statement of the agreement between the Guarantors relating to all
matters set forth herein and supersedes all other oral and written
understandings to the contrary.

        11.      Counterparts. This Agreement may be executed in separate
counterparts, each of which will be an original and all of which taken together
will constitute one and the same agreement.

The Warrant and the securities issuable upon exercise of this Warrant (the
"Securities") have not been registered under the Securities Act of 1933 (the
"Securities Act") or under any state securities or Blue Sky laws ("Blue Sky
Laws"). No transfer, sale, assignment, pledge, hypothecation or other
disposition of this Warrant or the Securities or any interest therein may be
made except (a) pursuant to an effective registration statement under the
Securities Act and any applicable Blue Sky Laws or (b) if the Company has been
furnished with both an opinion of counsel for the holder, which opinion and
counsel shall be reasonably satisfactory to the Company, to the effect that no
registration is required because of the availability of an exemption from
registration under the Securities Act and applicable Blue Sky Laws, and
assurances that the transfer, sale, assignment, pledge, hypothecation or other
disposition will be made only in compliance with the conditions of any such
registration or exemption.

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK
                              OF CAFE ODYSSEY, INC.

WARRANT NO. PL-1                                          Bloomington, Minnesota
                                                               November 16, 1998

         This certifies that, for value received, STEPHEN D. KING, or his
successors or assigns ("Holder") is entitled to purchase from Cafe Odyssey, Inc.
(the "Company") Forty Thousand (40,000) fully paid and nonassessable shares (the
"Shares") of the Company's Common Stock, $.01 par value (the "Common Stock"), at
any time and from time to time from the date hereof until November 16, 2003, at
an exercise price equal to the lower of (i) $0.75 or (ii) the price per share at
which the Company sells Common Stock or issues warrants or options in any public
or private transaction which is consummated between the date of this Warrant and
the earlier of (a) the date of exercise of this Warrant and (b) the date on
which no Guarantees by the original Holder of indebtedness of the Company to
Provident Bank, an Ohio banking corporation, are still outstanding (the
"Exercise Price"), subject to adjustment as herein provided.

         This Warrant is subject to the following provisions, terms and
conditions:

         1.   Exercise of Warrant.

              a. Exercise for Cash. The rights represented by this Warrant may
         be exercised by the Holder, in whole or in part (but not as to a
         fractional share of Common Stock), by the surrender of this Warrant
         (properly endorsed, if required, at the Company's principal office in
         Bloomington, Minnesota, or such other office or agency of the Company
         as the Company may designate by notice in writing to the Holder at the
         address of such Holder appearing on the books of the Company at any
         time within the period above named), and upon payment to it by
         certified check, bank draft or cash of the purchase price for such
         Shares. The Company agrees that the Shares so purchased shall have and
         are deemed to be issued to the Holder as the record owner of such
         Shares as of the close of business on the date on which this Warrant
         shall have been surrendered and payment made for such Shares as
         aforesaid. Certificates for the Shares of Common Stock so purchased
         shall be delivered to the Holder within a reasonable time, not
         exceeding ten (10) days, after the rights represented by this Warrant
         shall have been so exercised, and, unless this Warrant has expired, a
         new Warrant representing the number of Shares, if any, with respect to
         which this Warrant shall not then have been exercised shall also be
         delivered to the Holder within such time. The Company may require that
         any such new 


<PAGE>   8



         Warrant or any certificate for Shares purchased upon the exercise 
         hereof bear a legend substantially similar to that which is contained 
         on the face of this Warrant.

              b. Cashless Exercise. Upon receipt of a notice of cashless
         exercise, the Company shall deliver to the Holder (without payment by
         the Holder of any exercise price) that number of Shares that is equal
         to the quotient obtained by dividing (x) the value of the Warrant on
         the date that the Warrant shall have been surrendered (determined by
         subtracting the aggregate exercise price for the Shares in effect on
         the Exercise Date from the aggregate Fair Market Value (hereinafter
         defined) for the Shares by (y) the Fair Market Value of one share of
         Common Stock. A notice of "cashless exercise" shall state the number of
         Shares as to which the Warrant is being exercised. "Fair Market Value"
         for purposes of this Section (b) shall mean the average of the Common
         Stock closing prices reported by the principal exchange on which the
         Common Stock is traded, or the last sale prices as reported by the
         National Association of Securities Dealers, Inc. Automated Quotation
         System ("Nasdaq") National Market or SmallCap Market, as the case may
         be, for the ten (10) business days immediately preceding the Exercise
         Date or, in the event no public market shall exist for the Common Stock
         at the time of such cashless exercise, Fair Market Value shall mean the
         fair market value of the Common Stock as the same shall be determined
         in the good faith discretion of the Board of Directors, after full
         consideration of all factors then deemed relevant by such Board in
         establishing such value, including by way of illustration and not
         limitation, the per share purchase price of Common Stock or per
         security convertible into one share of Common Stock of the most recent
         sale of shares of Common Stock or securities convertible into Common
         Stock by the Company after the date hereof all as evidenced by the vote
         of a majority of the directors then in office.

         2.   Transferability of This Warrant. This Warrant is issued upon the
following terms, to which each Holder consents and agrees:

              a. Until this Warrant is transferred on the books of the Company,
         the Company will treat the Holder of this Warrant registered as such on
         the books of the Company as the absolute owner hereof for all purposes
         without being affected by any notice to the contrary.

              b. This Warrant may not be exercised, and this Warrant and the
         Shares underlying this Warrant shall not be transferable, except in
         compliance with all applicable state and federal securities laws,
         regulations and orders, and with all other applicable laws, regulations
         and orders.

              c. The Warrant may not be transferred, and the Shares underlying
         this Warrant may not be transferred, without the Holder obtaining an
         opinion of counsel satisfactory in form and substance to the Company's
         counsel stating that the proposed transaction will not result in a
         prohibited transaction under the Securities Act of 1933, as amended
         ("Securities Act"), and applicable Blue Sky laws. By accepting this
         Warrant, the Holder agrees to act in accordance with any conditions
         reasonably imposed on such transfer by such opinion of counsel.

              d. Neither this issuance of this Warrant nor the issuance of the
         Shares underlying this Warrant have been registered under the
         Securities Act.

         3.   Certain Covenants of the Company. The Company covenants and agrees
that all Shares which may be issued upon the exercise of the rights represented
by this Warrant, upon issuance and full payment for the Shares so purchased,
will be duly authorized and issued, fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issue hereof, except those that
may be


                                       2

<PAGE>   9


created by or imposed upon the Holder or its property, and without limiting the
generality of the foregoing, the Company covenants and agrees that it will from
time to time take all such actions as may be requisite to assure that the par
value per share of the Common Stock is at all times equal to or less than the
effective purchase price per share of the Common Stock issuable pursuant to this
Warrant. The Company further covenants and agrees that during the period within
which the rights represented by this Warrant may be exercised, the Company will
at all times have authorized and reserved free of preemptive or other rights for
the exclusive purpose of issue upon exercise of the purchase rights evidenced by
this Warrant, a sufficient number of shares of its Common Stock to provide for
the exercise of the rights represented by this Warrant.

         4.   Adjustment of Exercise Price and Number of Shares. The Exercise
Price and number of Shares are subject to the following adjustments:

              a. Adjustment of Exercise Price for Stock Dividend, Stock Split or
         Stock Combination. In the event that (i) any dividends on any class of
         stock of the Company payable in Common Stock or securities convertible
         into or exercisable for Common Stock ("Common Stock Equivalents") 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 its outstanding shares of Common Stock,
         by reclassification or otherwise, then, in any such event, the Exercise
         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 Exercise Price, by (b) the
         total number of shares of Common Stock outstanding immediately after
         such event, and the resulting quotient shall be the adjusted Exercise
         Price per share. No adjustment of the Exercise Price shall be made if
         the amount of such adjustment shall be less than $.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 the next subsequent adjustment which, together with any
         adjustment or adjustments so carried forward, shall amount to not less
         than $.05 per share.

         b. Adjustment of Exercise Price for Dilutive Common Stock Issuances. If
         at any time prior to the exercise of this Warrant in full but following
         the date on which no Guarantees by the original Holder of indebtedness
         of the Company to Provident Bank are still outstanding, the Company
         shall (i) issue or sell any Common Stock Equivalents without
         consideration or for consideration per share (in cash, property or
         other assets) less than the Exercise Price per share on the date of
         such issuance or sale or (ii) fix a record date for the issuance of
         subscription rights, options or warrants to all holders of Common Stock
         entitling them to subscribe for or purchase Common Stock (or Common
         Stock Equivalents) at a price (or having an exercise or conversion
         price per share) less than the Exercise Price on the record date
         described below, the Exercise Price shall be adjusted so that the
         Exercise Price shall equal the price determined by multiplying the
         Exercise Price in effect immediately prior to the date of such sale or
         issuance (which date in the event of distribution to shareholders shall
         be deemed to be the record date set by the Company to determine
         shareholders entitled to participate in such distribution) by a
         fraction, the numerator of which shall be (i) the number of shares of
         Common Stock outstanding on the date of such sale or issuance, plus
         (ii) the number of additional shares of Common Stock which the
         aggregate consideration received by the Company upon such issuance or
         sale (plus the aggregate of any additional amount to be received by the
         Company upon the exercise of such subscription rights, options or
         warrants) would purchase at such current market price per share of the
         Common Stock; and the denominator of which


                                       3

<PAGE>   10



         shall be (i) the number of shares of Common Stock outstanding on the
         date of such issuance or sale, plus (ii) the number of additional
         shares of Common Stock offered for subscription or purchase (or into
         which the Common Stock Equivalents so offered are exercisable or
         convertible). Any adjustments required by this paragraph shall be made
         immediately after such issuance or sale or record date, as the case may
         be. Such adjustments shall be made successively whenever such event
         shall occur.

              c. Adjustment of Number of Shares Purchasable on Exercise of
         Warrants. Upon each adjustment of the Exercise Price pursuant to this
         Section, the Holder shall thereafter (until another such adjustment) be
         entitled to purchase at the adjusted Exercise 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 Exercise Price in effect prior to such
         adjustment) by the Exercise Price in effect prior to such adjustment
         and dividing the product so obtained by the adjusted Exercise Price.

              d. Notice as to Adjustment. Upon any adjustment of the Exercise
         Price and any increase or decrease in the number of shares of Common
         Stock purchasable upon the exercise of the Warrant, then, and in each
         such case, the Company within thirty (30) days thereafter shall give
         written notice thereof, by first class mail, postage prepaid, addressed
         to each Holder as shown on the books of the Company, which notice shall
         state the adjusted Exercise Price and the increased or decreased number
         of shares purchasable upon the exercise of the Warrants, and shall set
         forth in reasonable detail the method of calculation and the facts upon
         which such calculation is based.

              e. Effect of Reorganization, Reclassification, Merger, etc. If at
         any time while any Warrant is outstanding there should be any capital
         reorganization 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 4(a) 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, which is
         effected in such a manner that the holders of Common Stock shall be
         entitled to receive cash, stock, securities, or assets with respect to
         or in exchange for Common Stock, then, as a part of such transaction,
         lawful provision shall be made so that each Holder shall have the right
         thereafter to receive, upon the exercise hereof, 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 to which the property of the Company has been sold,
         conveyed, leased or otherwise transferred, as the case may be, which
         the Holder would have been entitled to receive 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. In any such case, appropriate
         adjustments (as determined by the Board of Directors of the Company)
         shall be made in the application of the provisions set forth in this
         Warrant (including the adjustment of the Exercise Price and the number
         of Shares issuable upon the exercise of the Warrants) to the end that
         the provisions set forth herein shall thereafter be applicable, as near
         as reasonably may be, in relation to any shares or other property
         thereafter deliverable upon the exercise of the Warrants as if the
         Warrants had been exercised immediately

         stock, such consolidation, merger, sale, conveyance, lease or other
         transfer and the Warrant Holders had carried out the terms of the
         exchange as provided for by such capital reorganization, 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
