             business transacted at a special meeting that is not included in
             those stated purposes not be void ab initio, but shall be voidable
             by or on behalf of the Company unless all of the Members entitled
             to vote thereat have waived notice of the meeting or consented to
             such action in accordance with this Operating Agreement.

If a regular meeting of the Members has not been held during the immediately
preceding fifteen (15) months, any Member or Members holding three percent (3%)
or more of all voting Membership Interests of the Company may demand a regular
meeting of the Members. Any Member or Members holding ten percent (10%) or more
of all voting Membership Interests of the Company may demand a special meeting
of the Members. The demand for a regular or a special meeting by the Members
shall be given in writing to the Chief Manager or the Treasurer or Chair of the
Board of Managers of the Company. Within ten (10) business days after receipt of
such demand, the Board of Managers shall cause a meeting of the Members to be
called and held on notice no later than thirty (30) days after receipt of the
demand, all at the expense of the Company. If the Board of Managers fails to
cause a meeting to be called and held as required by this Article, the Member or
Members making the demand may call the meeting by giving notice as required by
Article 2.4 of this Operating Agreement, all at the expense of the Company.

2.4    NOTICE.

Notice of all meetings of the Members shall be given to every holder of voting
Membership Interests at his or her address as shown in the required records of
the Company, except where (i) the meeting is an adjourned meeting and the date,
time and place of the meeting were announced at the time of adjournment; or (ii)
the following have been mailed by first class mail to a Member at the address in
the limited liability Company required records and returned undeliverable:

       (a)   Two consecutive annual meeting notices and notice of any special
             meetings held during the period between the two annual meetings;
             and

       (b)   All payments of distributions, provided there are at least two sent
             during a 12-month period; and

       (c)   Written notice of the Member's current address has not been
             received by the Company.

The notice of a meeting of the Members shall be given at least five (5) business
days before the date of the meeting, and not more than sixty (60) days before
the date of the meeting. The notice shall contain the date, time and place of

the meeting. The notice may also contain any other information deemed necessary
or desirable by the Board of Managers or by any other person or persons calling
the meeting.

2.5    WAIVER OF NOTICE.

A Member may waive notice of a meeting of the Members. A waiver of notice by a
Member entitled to notice shall be effective whether given before, at or after
the meeting, and whether given in writing, orally or by attendance. Attendance
by a Member at a meeting shall be a waiver of notice of that meeting except
where the Member objects at the beginning of the meeting to the transaction of
business because the meeting is not lawfully called or convened, or objects
before a vote on an item of business because the item may not lawfully be
considered at that meeting and does not participate in the consideration of the
item at that meeting.

2.6    QUORUM.

The holders of a majority of the voting power of the Membership Interests
entitled to vote at a meeting, present in person or by proxy, shall constitute a
quorum for the transaction of business. If a quorum is present when a duly
called or held meeting is convened, the Members present may continue to transact
business until adjournment, even though the withdrawal of a number of Members
originally present leaves less than the proportion or number otherwise required
for a quorum.

2.7    VOTING RECORD DATE.

The Board of Managers may fix a date not more than sixty (60) days before the
date of a meeting of the Members as the date for the determination of the
holders of voting Membership Interests entitled to notice of and to vote at the
meeting. When a date is so fixed, only Members on that date are entitled to
notice of and permitted to vote at that meeting of Members. If no record date is
fixed for the determination of Members entitled to notice of or to vote at a
meeting of Members, the date on which notice of the meeting is mailed shall be
the record date for such determination of Members. When a determination of
Members entitled to vote at any meeting of Members has been made as provided in
this Article, such determination shall apply to any adjournment thereof.

2.8    VOTE BY BALLOT.

Upon the demand of any Member, the vote for Managers, the vote upon any question
before the vote for Managers, or the vote upon any question before the meeting
shall be by ballot.

       (a)   GENERAL. In general, the Members shall take action by the
             affirmative vote of the owners of the greater of:

             (i)    A majority of the voting power of the Membership Interests
                    present and entitled to vote on that item of business
                    (proxies without authority on a matter not being considered
                    for purposes of such matter); or

Operating Agreement                     3
BC Restaurants, LLC.

<Page>

             (ii)   A majority of the voting power that would constitute a
                    quorum for the transaction of business at the meeting; or

             (iii)  If the Articles of Organization or any Membership Control
                    Agreement requires a larger proportion of the voting power
                    of the Members Interest than is required by this Operating
                    Agreement for a particular action, then the Articles of
                    Organization or the Member Control Agreement shall control.

       (b)   VOTING BY CLASS. In any case where a class or series of Membership
             Interests is entitled to vote as a class or series, the matter
             being voted upon must receive:

             (i)    The affirmative vote of the owners of the required
                    proportion of the Membership Interests of each class or
                    series present at such meeting, as set forth in Subsection
                    A. above; or

             (ii)   The affirmative vote of the owners of the required
                    proportion of the total outstanding Membership Interests of
                    all classes or series entitled to vote, as set forth in
                    Subsection A, above;

unless the Articles of Organization or a Membership Control Agreement requires a
larger proportion.

Unless otherwise stated in the Articles of Organization, a Membership Control
Agreement or in this Operating Agreement, in the case of voting as a class or
series, the minimum percentage of the total voting power of Membership Interests
of the class or series that must be present to constitute a quorum for such vote
shall be equal to the minimum percentage of all Membership Interests entitled to
vote required to be present under Article 2.6 hereof.

2.10   STATEMENT OF MEMBERSHIP INTEREST.

At the request of any Member, the Company shall state in writing the particular
Membership Interest owned by that Member as of the moment the Company makes the
statement. The statement must describe the Member's rights to vote, to share in
profits and losses, and to share in distributions, as well as any assignment of
the Member's economic or governance rights then in effect.

2.11   VOTING POWER.

Except as otherwise set forth in the Articles of Organization or in a Member
voting agreement or Membership Control Agreement, Members have voting power in
proportion to the value of the contributions of the Members as reflected in the
required records. No assignee of the economic rights of any Member shall have
any vote or governance rights unless such assignee is a Member with other
governance rights or complies with the requirements hereof.

2.12   VOTING RIGHTS.

       (a)   CLASSES. The total authorized Membership Interests of the Company
             shall consist of the following classes:

             (i)    Class I: Voting participating Membership Interests known as
                    "Voting Membership Interests," which may be divided into not
                    more than 1,000 Voting Membership units.

             (ii)   Class II: Nonvoting participating Membership Interests known
                    as "Nonvoting Membership Interests," which may be divided

       (b)   Rights. The Membership Interests will have the following rights:

             (i)    VOTING RIGHTS. All voting rights shall be vested in the
                    Voting Membership Interests, and all actions by the Members
                    of the Company shall be made by the holders of said Voting
                    Membership Interests. The holders of all Voting Membership
                    Interests shall have voting rights in direct proportion to
                    his or her Voting Membership Interests as reflected on the
                    required records of the Company.

             (ii)   ECONOMIC RIGHTS. All profits and losses, and all
                    distributions (including distributions upon liquidation and
                    termination distributions), of the Company as provided under
                    California law shall be allocated and paid only to the
                    holders of Voting and Nonvoting Membership Interests in
                    direct proportion to his or her percentage of Membership
                    Interests as reflected in the required records of the
                    Company, or as otherwise allocated in accordance with any
                    Membership Control Agreement between the Company and its
                    Members.

             (iii)  DISTRIBUTIONS IN KIND. No Member of any class or series of
                    Membership Interests shall have any right to receive
                    distributions in kind; provided that any Member may be
                    required to receive distributions in kind of an amount
                    similar to the percentage interest of such Member in
                    distributions of the Company.

             (iv)   JOINTLY OWNED INTERESTS. Membership Interests owned by two
                    or more individuals or entities may be voted by any one of
                    them unless the Company receives written notice from any one
                    of them denying the authority of that co-owner to vote the
                    Membership Interests.

             (v)    ENTITIES. Membership Interests of the Company reflected in
                    the required records as being held by another domestic or
                    foreign organization may be voted by the Chief Managers,
                    Chief Executive Officer, or another legal

Operating Agreement                     5
BC Restaurants, LLC.

<Page>

                    representative of that organization. Membership Interests
                    under the control of a person in a capacity as a personal
                    representative, administrator, executor, guardian,
                    conservator, attorney in fact, trustee in bankruptcy or
                    receiver may be voted by the person, either in person or by
                    proxy, without reflecting in the required records those
                    Membership Interests in the name of the person (provided
                    there is court authority for such bankruptcy trustee or
                    receiver). Membership Interests registered in the name of a
                    trust or any other organization not described herein may be
                    voted either in person or by proxy by the trustee or legal
                    representative thereof.

             (vi)   COMPANY AND SUBSIDIARIES. Membership Interests of the
                    Company reflected in the required records as being held by
                    the Company or a subsidiary of the Company shall not be
                    entitled to vote on any matter. Membership Interests held in
                    the name of or under the control of the Company or a
                    subsidiary in a fiduciary capacity shall also not be
                    entitled to vote on any matter, except to the extent that
                    the settlor or beneficial owner possesses and exercises a
                    right to vote or gives the Company binding instructions on
                    how to vote the Membership Interests.

             (vii)  SECURITY INTERESTS. The grant of a security interest in a
                    Membership Interest does not entitle the holders of the
                    security interest to vote or to exercise any governance
                    right relating thereto.

2.13   PROXIES.

A Member may not grant any proxy to any person who is an assignee of any
Member's economic rights and who is not also a Member. A Member may otherwise
cast or authorize the casting of a vote by filing a written appointment of a
proxy with a Manager of the Company at or before the meeting at which the
appointment is to be effective. An appointment of a proxy shall be valid if
signed by any representative or other party authorized to vote such Membership
Interest hereunder, and may be authorized by any form of electronic
transmission. Any one of two or more authorized proxies are allowed to vote with
respect to specific instructions and a majority shall be necessary to vote with
respect to any particular item of business where there are no specific
instructions; provided that if the proxies are equally divided, the Membership
Interests must not be voted on that matter. The appointment of a proxy shall be
valid for eleven (11) months unless a longer period is expressly provided in the
appointment; provided that no proxy shall be irrevocable and any purported
irrevocable proxy shall be void, and the Member revoking such proxy shall not be
liable for damages. Proxies may be terminated at will, effective upon filing a
revocation thereof or filing a new proxy with the Company. Proxies shall be
valid until notice of the death or incapacity of the Member is received by a
Manager of the Company.

2.14   ELECTRONIC COMMUNICATIONS.

A conference among Members by any means of communication through which the
Members may simultaneously hear each other during the conference shall
constitute a meeting of the

Operating Agreement                     6
BC Restaurants, LLC.

<Page>

Members, if the same notice is given of the conference as would be required by
this Article for a meeting, and if the number of Members participating in the
conference would be sufficient to constitute a quorum at a meeting.
Participation in a meeting by such means shall constitute presence in person at
the meeting, except as provided in Article 2.5 hereof.

2.15   ACTION WITHOUT A MEETING.

An action required or permitted to be taken at a meeting of the Members may be
taken without a meeting by written action signed by a majority of the Members
entitled to vote on that action. The written action shall be effective when it
has been signed by all of those Members, unless a different effective time is
provided in the written action.

2.16   VOTING AND CONTROL AGREEMENTS.

The Members may enter into Member voting agreements and/or Membership Control
Agreements in accordance with the applicable law. To the extent the terms of any
such Member voting agreement or Membership Control Agreement may be in
contradiction of any terms of this Operating Agreement, the terms of such Member
voting agreement or Membership Control Agreement shall be controlling, and the
conflicting terms of this Operating Agreement shall be null and void.

                           ARTICLE 3 BOARD OF MANAGERS

3.1    MANAGER.

3.2    BOARD TO MANAGE.

The business and affairs of the Company shall be managed by or under the

Membership Interests entitled to vote for Managers may, by unanimous affirmative
vote, take any action required or permitted to be taken by the Board of
Managers, in which situation the actions shall be deemed accepted by the Board
of Managers, but without liability of the Managers therefor.

3.3    NUMBER.

The number of Managers shall be set from time to time by resolution of the
Members. The Board of Managers may, at any time, increase the number of Managers
up to the maximum number set by resolution of the Members, or may decrease the

of a Manager other than a Manager named by the Board of Managers to fill a
vacancy.

A Manager of the Company shall not be personally liable to the Company or its
Members for monetary damages for breach of fiduciary duty as a Manager, except

intentional misconduct or a knowing violation of law, (c) under the

which the Manager derived an improper personal benefit. If the Beverly-Killea
Limited Liability Company Act is amended after this Article 3.6 becomes
effective to authorize action further eliminating or limiting the personal
liability of Managers, then the liability of a Manager of the Company shall be
eliminated or limited to the fullest extent permitted by the Beverly-Killea
Limited Liability Company Act, as so amended. Any repeal or modification of this
section by the Members of the Company shall not adversely affect any right or
protection of a Manager of the Company existing at the time of such repeal or
modification.

3.7    REGULAR MEETINGS.

A regular meeting of the Board of Managers shall be held without notice other
than this Article immediately after and at the same place as each regular
meeting of the Members at which Manager are elected. The Board of Managers may
provide, by resolution at a meeting of the Board of Managers, the time and
place, either within or without the State of California, for the holding of
additional regular meetings of the Board of Managers without notice other than
such resolution.

3.8    SPECIAL MEETINGS.

Special meetings of the Board of Managers may be called from time to time by or

the place of the meeting to another location.

3.9    NOTICE.

Notice of any special meeting shall be given at least ten (10) business days
prior thereto by written notice mailed to each Manager at his or her business

Operating Agreement                     8
BC Restaurants, LLC.

<Page>

such notice shall be deemed to be delivered when deposited in the United States
mail so addressed, with postage thereon prepaid. If notice be given by telegram
or similar personal overnight delivery, such notice shall be deemed to be
delivered when delivered to the forwarding Company. A Manager may waive notice
of a meeting of the Board of Managers. The notice need not state the purpose of
the meeting.

3.10   WAIVER OF NOTICE.

A waiver of notice by a Manager entitled to notice shall be effective whether
given before, at or after the meeting, and whether given in writing, orally or
by attendance. Attendance by a Manager at a meeting shall be a waiver of notice
of that meeting, except where the Manager objects at the beginning of the
meeting to the transaction of business because the meeting is not lawfully
called or convened and does not participate in the meeting thereafter.

3.11   QUORUM.

A majority of the Managers currently holding office present at a duly called
meeting shall constitute a quorum for the transaction of business. In the
absence of a quorum, a majority of the Managers present may adjourn a meeting
from time to time until a quorum is present. If a quorum is present when a duly
called or held meeting is convened, the Managers present may continue to
transact business until adjournment, even though the withdrawal of a number of
Managers originally present leaves less than the number otherwise required for a
quorum.

3.12   ELECTRONIC COMMUNICATIONS.

A conference among Managers by any means of communication through which the
Managers may simultaneously hear each other during the conference shall
constitute a meeting of the Managers, if the same notice is given of the
conference as would be required by this Article for a meeting, and if the number
of Managers participating in the conference would be sufficient to constitute a
quorum at a meeting. Participation in a meeting by such means shall constitute
presence in person at the meeting.

3.13   PRESUMPTION OF ASSENT.

A Manager who is present at a meeting of the Board of Managers when an action is
approved by the affirmative vote of a majority of the Managers present is
presumed to have assented to the action approved, unless the Manager objects at
the beginning of the meeting to the transaction of business because the meeting
is not lawfully called or convened and does not participate thereafter in the
meeting, or votes against the action at the meeting or is prohibited from voting
on the action due to a conflict of interest.

3.14   ABSENT MANAGER.

A Manager may give advance written consent or opposition to a proposal to be
acted on at a Board of Managers meeting. If the Manager is not present at the
meeting, consent or opposition to a proposal shall not constitute presence for
purposes of determining the existence of a quorum, but consent or opposition
shall be counted as a vote in favor of or against the proposal and shall

Operating Agreement                     9
BC Restaurants, LLC.

be entered in the minutes or other record of action at the meeting, if the
proposal acted on at the meeting is substantially the same or has substantially
the same effect as the proposal to which the Manager has consented or objected.

       (a)   WRITTEN ACTION PERMITTED. Any action required or permitted to be
             taken at a meeting of the Board of Managers may be taken by written
             action signed by all of the Managers. Except as specifically set
             forth herein or in any Membership Control Agreement, Members shall
             take action by the affirmative vote of a majority of the voting
             power of all Membership Interests entitled to vote present (in
             person or by proxy) at any meeting of the Members at which a quorum
             is present. Any action required or permitted to be taken at a
             meeting of the Members may be taken by written action signed by all
             of the Members with Membership Interests entitled to vote. Any
             written action may be executed in one or more counterparts, each of
             which shall be deemed an original, but all of which shall together
             constitute one and the same instrument.

       (b)   EFFECTIVE DATE. The written action shall be effective when signed
             by the required number of Managers, unless a different effective
             time is provided in the written action.

       (c)   NOTICE TO MANAGER. When written action is permitted to be taken by
             less than all Managers, all Managers shall be notified immediately
             of its text and effective date. Failure to provide the notice shall
             not invalidate the written action. A Manager who does not sign or
             consent to the written action shall have no liability for the
             action or actions taken thereby.

3.16   RESIGNATION.

A Manager may resign at any time by giving written notice to the Company. The
resignation shall be effective without acceptance when the notice is given to
the Company, unless a later effective time is specified in the notice.

3.17   REMOVAL.

Any one or all of the Managers may be removed at any time, with or without
cause, by the affirmative vote of the holders of power sufficient to elect such
Manager; provided, however, that if the Company has cumulative voting, unless
the entire Board of Managers is removed simultaneously, a Manager shall not be
removed from the Board of Managers if there are cast against removal of the
Manager the votes sufficient to elect the Manager at an election of the entire
Board of Managers under cumulative voting. A Manager may be removed at any time,
with or without cause, by the affirmative vote of a majority of the remaining
Managers present if the Manager was named by the Board of Managers to fill a
vacancy, and the Members have not elected Managers in the interval between the
time of appointment to fill the vacancy and the time

subject to the provisions of any Membership Control Agreement.

3.18   VACANCIES.

Any vacancy occurring on the Board of Managers resulting from the death,
resignation, removal or disqualification of a Manager may be filled by the
affirmative vote of a majority of the remaining Managers, even though less than
a quorum. Vacancies on the Board of Managers resulting from newly created
Manager positions may be filled by the affirmative vote of a majority of the
Managers serving at the time of the increase. A Manager elected to fill a
vacancy shall hold office until a qualified successor is elected by the Members
at the next regular or special meeting of the Members, or until his or her
earlier death, resignation, removal or disqualification.

3.19   COMPENSATION.

Managers and any Member of any committee of the Company, whether contemplated by
this Operating Agreement or otherwise provided for by resolution of the Board of
Managers, shall receive such compensation as may be determined from time to time
by resolution of the Board of Managers. No such payment shall preclude any
Manager from serving the Company in any other capacity and receiving
compensation therefor.

                              ARTICLE 4 COMMITTEES

4.1    GENERALLY.

By resolution approved by the affirmative vote of a majority of the Managers
holding office may establish committees having the authority of the Board of
Managers in the management of the business of the Company to the extent provided

Board of Managers requiring the approval of more than a majority of the Managers

Managers and its actions are approved by such required percentage. Committees
other than special litigation committees shall be subject at all times to the
direction and control of the Board of Managers.

shall hold his or her position until his or her successor is elected and has
qualified, or until his or her earlier death, resignation, removal or
disqualification. The election or appointment of a person as an officer or agent
shall not, of itself, create contract rights.

An officer may resign at any time by giving written notice to the Company. The
resignation shall be effective without acceptance when the notice is given to
the Company, unless a later effective date is specified in the notice.

                ARTICLE 7 MEMBERSHIP INTERESTS AND THEIR TRANSFER

7.1    LIMITATIONS BY OTHER AGREEMENTS.

The provisions of this Article are limited in their entirety by the provisions
of the Articles of Organization, any Membership Control Agreement or Member
voting agreement, or the mandatory provisions of the Act thereof, and any
provision of this Article in contradiction with any such article, agreement or
law shall be null and void.

Any issuance of any Membership Interest of the Company or any options, warrants,
Membership rights, convertible debentures or similar securities shall require
the affirmative vote of a majority of the Board of Managers of the Company, and
such action shall be necessary to accept contributions, make contribution
agreements or make contribution allowance agreements in accordance with the Act.

7.2    TRANSFER OF MEMBERSHIP INTERESTS RESTRICTED.

A Member may assign the Member's full Membership Interest only by assigning all
of the Member's governance rights coupled with a simultaneous assignment to the
same assignee of all of the Member's economic rights. A Member's economic rights
and governance rights are assignable, in whole or in part, only as provided in
this Article and after compliance with the provisions hereof. Any Member may
assign his or her Membership Interests freely to any

Operating Agreement                    15
BC Restaurants, LLC.

<Page>

Member or non-Member, except as otherwise provided in this Operating Agreement,
the Articles of Organization or any Membership Control Agreement.

7.3    TRANSFER OF MEMBERSHIP INTERESTS.

Transfer of Membership Interests of the Company shall be made only in the
required records of the Company by the record holder thereof or by his or her
legal representative who shall furnish proper evidence of authority to transfer
and compliance with the provisions of this Article. The person in whose name
Membership Interests stand in the required records of the Company shall be
deemed by the Company to be the owner thereof for all purposes unless a
different beneficial owner shall have been designated pursuant to this Operating
Agreement.

7.4    INDEBTEDNESS OF MEMBERS.

The Company shall have a first lien on all Membership Interests and upon all
distributions declared upon the same for any indebtedness of the respective
holders thereof to the Company. No Membership Interest or the economic or
governance rights therein shall be considered a certified security, uncertified
security, chattel paper, instrument or account under California Law; but each
Membership Interest, economic right and governance right shall be deemed a
general intangible.

7.5    TRANSFER AGENT AND REGISTRAR.

The Board of Managers may appoint one or more transfer agents, transfer clerks,
or registrars to maintain the required records of the Company and may require
any statements which may be used to describe any Membership Interests to bear
the signature or signatures of any of them; provided that no such statement
shall be a negotiable instrument and no such statement may serve as a vehicle by
which the transfer of any Membership Interest may be effected.

7.6    ASSIGNMENT OF ECONOMIC RIGHTS PERMITTED.

Except as provided in this Article, a Member's economic rights are transferable
in whole or in part.

       (a)   RESTRICTIONS OF ASSIGNMENT OF MEMBERSHIP INTERESTS. A restriction
             on the assignment of Membership Interests or any part thereof may
             be imposed in the Articles of Organization or by an agreement among
             or other written action by Members or among them and the Company. A
             restriction is not binding with respect to Membership Interests
             reflected in the required records before the adoption of the
             restriction, unless the owners of those Membership Interests are
             parties to the agreement or voted in favor of the restriction.

       (b)   NOTICE IN REQUIRED RECORDS. A written restriction on the assignment
             of economic rights that is not manifestly unreasonable under the
             circumstances and is noted conspicuously in the required records
             may be enforced against the owner of the restricted economic rights
             or a successor or transferee of the owner including a pledgee or a
             legal representative. Unless noted conspicuously in the required

Operating Agreement                    16
BC Restaurants, LLC.

<Page>

             records, a restriction, even though permitted by this Article, is
             ineffective against a person without knowledge of the restriction.

7.7    EFFECT OF ASSIGNMENT OF ECONOMIC RIGHTS.

An authorized assignment of a Member's economic rights entitles the assignee to
receive, to the extent assigned, only the share of profits and losses and the
distributions to which the assignor would otherwise be entitled. An assignment
of a Member's economic rights does not dissolve the Company and does not entitle
or empower the assignee to become a Member, to exercise any governance rights,
to receive any notices from the Company, or to cause dissolution. The assignment
of economic rights may not allow the assignee to control the assignor Member's
exercise of governance rights.

                    ARTICLE 8 CONTRIBUTIONS AND DISTRIBUTIONS

8.1    POWER TO MAKE DISTRIBUTIONS.

Except as specifically provided in the Articles of Organization, any Membership
Control Agreement or this Operating Agreement to the contrary, the Board of
Managers may authorize, and cause the Company to make, a distribution only if
the Board of Managers determines, in accordance with California law, that the
Company will be able to pay its debts in the ordinary course of business after
making the distribution and the Board of Managers does not know before the
distribution is made that the determination was or has become erroneous. Such
determination shall be made as of the earlier of the date of cessation of
Membership or due date of payment (including the date debt is incurred) for a
redemption, or the authorization (if paid within 120 days) or the date of
payment (if after 120 days). For purposes of this Article, "distribution" means
a direct or indirect transfer of money or other property, other than Membership
Interests of the Company, with or without consideration, or an incurrence or
issuance of indebtedness by the Company to or for the benefit of its Members in
respect of its Membership Interests. A distribution may be in the form of an
operating distribution or a distribution in liquidation, or as consideration for
the purchase, redemption or other acquisition of the Company's Membership
Interests or otherwise.

8.2    RELIANCE.

For purposes of Article 8.1 and all other provisions of this Agreement, a
Manager, in good faith, is entitled to rely on information, opinions, reports,
or statements, including financial statements and other financial data, in each
case prepared or presented by:

       (a)   One or more Managers or employees of the Company whom the Managers
             reasonably believes to be reliable and competent in the matters
             presented; or

       (b)   Counsel, public accountants, or other persons as to matters that
             the Manager reasonably believes are within the person's
             professional or expert competence; or

Operating Agreement                    17
BC Restaurants, LLC.

<Page>

       (c)   A committee of the Board of Managers upon which the Manager does
             not serve, duly established in accordance with Article IV hereof,
             as to matters within its designated authority, if the Manager
             reasonably believes the committee to merit confidence; provided

       (d)   If the determination is made on the basis of financial information,
             it is prepared in accordance with accounting methods, or a fair
             valuation or other method, reasonable in the circumstances.

8.3    ALLOCATIONS AND DISTRIBUTIONS IN KIND.

Except as authorized in the Articles of Organization or any Membership Control
Agreement, distributions must be allocated in proportion to the value of the
contributions of the Members as reflected in the required records. Except as
provided in the Articles of Organization or any Membership Control Agreement, a
Member, regardless of the nature of the Member's contribution, has no right to
demand and receive any distribution in any form other than cash. Except as
provided in the Articles of Organization or any Membership Control Agreement, a
Member may not be compelled to accept a distribution of any asset in kind from
the Company to an extent greater than the percentage in which the Member shares
in distributions from the Company.

8.4    LIABILITY FOR ILLEGAL DISTRIBUTIONS.

       (a)   MEMBERS. A Member who receives a distribution made in violation of
             the Articles of Organization, this Operating Agreement or any
             Membership Control Agreement is liable (if timely action is brought
             within two (2) years of the date of distribution) to the Company,
             its receiver or other person winding up its affairs, or a Manager
             as provided by law, but only to the extent that the distribution
             received by the Member exceeded the amount that properly could have
             been paid under said provisions of California statutes.

       (b)   MANAGERS. A Manager shall only be liable for an improper
             distribution if


             (i)    The Manager is present at a meeting and fails to vote
                    against, or who consents in writing to, a distribution made
                    in violation of law or a restriction contained in the
                    Articles of Organization, this Operating Agreement or a
                    Membership Control Agreement;

             (ii)   The Manager fails to comply with the standard of conduct
                    provided by law; and

             (iii)  Action relating to such liability is commenced within two
                    (2) years of the date of distribution.

Under such circumstances, the Manager is liable to the Company jointly and
severally with all other Manager so liable and to other Manager, but only to the
extent that the distribution

Manager shall be entitled to pro-rata contribution from similarly situated
