Exhibit 10.20

AMENDMENT NUMBER FIVE TO CREDIT AGREEMENT

This AMENDMENT NUMBER FIVE TO CREDIT AGREEMENT (this “Fifth Amendment”) is
entered into as of March 22, 2006, by the lenders identified on the signature
pages hereof (the “Lenders”), WELLS FARGO FOOTHILL, INC., a California
corporation, as the arranger and administrative agent for the Lenders (in such
capacity, together with its successors and assigns, if any, in such capacity,
“Agent”; and together with the Lenders, the “Lender Group”), BUCA, INC., a
Minnesota corporation (“Parent”), and each of Parent’s Subsidiaries identified
on the signature pages hereof (such Subsidiaries, together with Parent, are
referred to hereinafter each individually as a “Borrower”, and individually and
collectively, jointly and severally, as the “Borrowers”), with reference to the
following:

WHEREAS, Borrowers and the Lender Group are parties to that certain Credit
Agreement, dated as of November 15, 2004, (as amended, , restated, supplemented,
or otherwise modified from time to time, the “Credit Agreement”);

WHEREAS, Parent has informed the Lender Group (a) that it intends to restate its
financial statements for the fiscal years 2000 through 2004 and for the first
three fiscal quarters in the fiscal year 2005 (the “Superseded Financial
Statements”) to correct for errors in the application of existing generally
accepted accounting principles and for other reasons previously disclosed to the
Lender Group, and (b) that the Superseded Financial Statements, and all other
quarterly and monthly financial statements of Parent for periods ended prior to
the last day of fiscal year 2005 heretofore delivered to the Lender Group
(together with the Superseded Financial Statements, the “Pre-Restatement
Financial Statements”), should no longer be relied upon;

WHEREAS, Parent has requested that the Lender Group waive any Events of Default
that have occurred and are continuing under the Credit Agreement as a result of
(a) Borrowers having failed to maintain a system of accounting that enables them
to produce financial statements in accordance with GAAP as required by
Section 5.1 of the Credit Agreement, or (b) the representations regarding the
Pre-Restatement Financial Statements contained in Section 4.11 of the Credit
Agreement being incorrect (the “Existing Events of Default”);

WHEREAS, Borrowers have requested that the Lender Group agree to certain
amendments of the Credit Agreement and waive the Existing Events of Default, as
set forth herein; and

WHEREAS, subject to the terms and conditions set forth herein, the Lender Group
is willing to make the amendment requested by Borrowers and waive the Existing
Events of Default, as set forth herein.

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

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
herein contained, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

 

1. Defined Terms. Capitalized terms used herein and not otherwise defined herein
shall have the meanings ascribed to them in the Credit Agreement, as amended
hereby.

 

2. Waiver. The Lender Group hereby agrees to waive, and hereby does waive, the
Existing Events of Default, provided, however, such waiver shall continue to be
effective only so long as (a) on or before April 7, 2006, Borrower shall
(i) have delivered to the Lender Group restated financial statements covering
not less than the periods covered by the Superseded Financial Statements (the
“Restated Financial Statements”) and (ii) be in compliance with Section 5.1 of
the Credit Agreement and (b) upon delivery of the Restated Financial Statements,
the representations and warranties regarding the Pre-Restatement Financial
Statements in Section 4.11 of the Credit Agreement being waived hereunder shall
be true and correct with reference to the Restated Financial Statements.

 

3. Amendments to Credit Agreement.

 

  (a) Section 2.3(d)(iii) of the Credit Agreement is hereby amended and restated
in its entirety to read as follows:

(iii) Each Protective Advance and each Overadvance shall be deemed to be an
Advance hereunder, except that no Protective Advance or Overadvance shall be
eligible to be a LIBOR Rate Loan and all payments on the Protective Advances
shall be payable to Agent solely for its own account. The Protective Advances
and Overadvances shall be repayable on demand, secured by the Agent’s Liens,
constitute Obligations hereunder, and bear interest at the rate applicable from
time to time to Advances that are Base Rate Loans. The provisions of this
Section 2.3(d) are for the exclusive benefit of Agent, Swing Lender, and the
Lenders and are not intended to benefit any Borrower in any way.

 

  (b) Section 2.4(b) of the Credit Agreement is hereby amended by inserting the
following as a new clause (vi):

(vi) Except as otherwise specifically provided in clause (b)(iii) above,
payments or prepayments of the principal of Advances shall be applied first to
Advances that are Base Rate Loans (with such Advances being deemed repaid in the
order in which made) to the full extent thereof before application to Advances
that are LIBOR Rate Loans.

 

  (c) Section 2.6(a) of the Credit Agreement is hereby amended and restated in
its entirety to read as follows:

(a) Interest Rates. Except as provided in clause (c) below, all Obligations
(except for undrawn Letters of Credit and except for Bank Product Obligations)
that have been charged to the Loan Account pursuant to the terms hereof shall
bear interest on the Daily Balance thereof as follows: (i) if the relevant
Obligation is an Advance (x) before the Revolver Increase Date, at a per annum
rate equal to the Base Rate plus 2.50 percentage points and (y) on or after the
Revolver Increase Date, at a per annum rate equal to the Base Rate or the LIBOR
Rate, as the case may be, plus the Applicable Margin and (ii) if the relevant
Obligation is the Term Loan A, at a per annum rate equal to the Base Rate plus
2.50 percentage points.

 

2

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

  (d) Section 2.6(d) of the Credit Agreement is hereby amended and restated in
its entirety to read as follows:

(d) Payment. Except as provided to the contrary in Section 2.17(a), the Fee
Letter or interest, Letter of Credit fees, and all other fees payable hereunder
shall be due and payable, in arrears, on the first day of each month at any time
that Obligations or Commitments are outstanding. Borrowers hereby authorize
Agent, from time to time, without prior notice to Borrowers, to charge all
interest and fees (when due and payable), all Lender Group Expenses (as and when
incurred), all charges, commissions, fees, and costs provided for in
Section 2.12(e) (as and when accrued or incurred), all fees and costs provided
for in the Fee Letter (when due and payable or as and when incurred, as the case
may be), and all other payments as and when due and payable under any Loan
Document (including the amounts due and payable with respect to the Term Loans
and including any amounts due and payable to the Bank Product Providers in
respect of Bank Products up to the amount of the Bank Product Reserve) to
Borrowers’ Loan Account, which amounts thereafter shall constitute Advances
hereunder and, subject to the provisions of Section 2.17 hereof, shall accrue
interest at the rate then applicable to Advances hereunder that are Base Rate
Loans. Any interest not paid when due shall be compounded by being charged to
Borrowers’ Loan Account and shall thereafter constitute Advances hereunder and,
subject to the provisions of Section 2.17 hereof, shall accrue interest at the
rate then applicable to Advances that are Base Rate Loans.

 

  (e) Section 2.8 of the Credit Agreement is hereby amended and restated in its
entirety to read as follows:

2.8 Crediting Payments; Clearance Charge. The receipt of any payment item by
Agent (whether from transfers to Agent by the Cash Management Banks pursuant to
the Cash Management Agreements or otherwise) shall not be considered a payment
on account unless such payment item is a wire transfer of immediately available
federal funds made to the Agent’s Account or unless and until such payment item
is honored when presented for payment. Should any payment item not be honored
when presented for payment, then Borrowers shall be deemed not to have made such
payment and interest shall be calculated accordingly. Anything to the contrary
contained herein notwithstanding, any payment item shall be deemed received by
Agent only if it is received into the Agent’s Account on a Business Day on or
before 11:00 a.m. (California time). If any payment item is received into the
Agent’s Account on a non-Business Day or after 11:00 a.m. (California time) on a
Business Day, it shall be deemed to have been received by Agent as of the
opening of business on the immediately following Business Day. From and after
the Closing Date, Agent shall be entitled to charge Borrowers for 2 Business
Days of ‘clearance’ at the rate then applicable under Section 2.6 to Advances
that are Base Rate Loans on all Collections that are received by Borrowers and
their Subsidiaries (regardless of whether forwarded by the Cash Management Banks
to Agent). This across-the-board 2 Business Day clearance charge on all
Collections of Borrowers and their Subsidiaries is acknowledged by the parties
to constitute an integral aspect of the pricing of the financing of Borrowers
and shall apply irrespective of whether or not there are any outstanding
monetary Obligations; the effect of such clearance charge being the equivalent
of charging interest on such Collections through the completion of a period
ending 2 Business Days after the receipt thereof. The parties acknowledge and
agree that the economic benefit of the foregoing provisions of this Section 2.8
shall be for the exclusive benefit of Agent.

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

  (f) The last paragraph of Section 2.12(a) of the Credit Agreement is hereby
amended and restated in its entirety to read as follows:

Borrowers and the Lender Group acknowledge and agree that certain Underlying
Letters of Credit may be issued to support letters of credit that already are
outstanding as of the Closing Date. Each Letter of Credit (and corresponding
Underlying Letter of Credit) shall be in form and substance acceptable to the
Issuing Lender (in the exercise of its Permitted Discretion), including the
requirement that the amounts payable thereunder must be payable in Dollars. If
Issuing Lender is obligated to advance funds under a Letter of Credit, Borrowers
immediately shall reimburse such L/C Disbursement to Issuing Lender by paying to
Agent an amount equal to such L/C Disbursement not later than 11:00 a.m.,
California time, on the date that such L/C Disbursement is made, if
Administrative Borrower shall have received written or telephonic notice of such
L/C Disbursement prior to 10:00 a.m., California time, on such date, or, if such
notice has not been received by Administrative Borrower prior to such time on
such date, then not later than 11:00 a.m., California time, on the Business Day
that Administrative Borrower receives such notice, if such notice is received
prior to 10:00 a.m., California time, on the date of receipt, and, in the
absence of such reimbursement, the L/C Disbursement immediately and
automatically shall be deemed to be an Advance hereunder and, thereafter,
subject to the provisions of Section 2.17 hereof, shall bear interest at the
rate then applicable to Advances that are Base Rate Loans under Section 2.6. To
the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrowers’
obligation to reimburse such L/C Disbursement shall be discharged and replaced
by the resulting Advance. Promptly following receipt by Agent of any payment
from Borrowers pursuant to this paragraph, Agent shall distribute such payment
to the Issuing Lender or, to the extent that Lenders have made payments pursuant
to Section 2.12(c) to reimburse the Issuing Lender, then to such Lenders and the
Issuing Lender as their interests may appear.

 

  (g) Section 2 of the Credit Agreement is hereby amended by inserting the
following as a new Section 2.17:

 

  2.17 LIBOR Option.

(a) Interest and Interest Payment Dates. In lieu of having interest charged at
the rate based upon the Base Rate, Borrowers shall have the option (the “LIBOR
Option”) to have interest on all or a portion of the Advances made on or after
the Revolver Increase Date be charged at a rate of interest based upon the LIBOR
Rate. Interest on LIBOR Rate Loans shall be payable on the earliest of (i) the
last day of the Interest Period applicable thereto, (provided, however, that,
subject to the following clauses (ii) and (iii), in the case of any Interest
Period greater than 3 months in duration, interest shall be payable at 3 month
intervals after the commencement of the applicable Interest Period and on the
last day of such Interest Period), (ii) the date on which an Event of Default
occurs, at the election of Agent, or (iii) the date on which this Agreement is
terminated pursuant to the terms hereof. On the last day of each applicable
Interest Period, unless Administrative Borrower properly has exercised the LIBOR
Option with respect thereto, the interest rate applicable to such LIBOR Rate
Loan automatically shall convert to the rate of interest then applicable to
Advances that are Base Rate Loans. At any time that an Event of Default has
occurred and is continuing, Borrowers no longer shall have the option to request
that Advances bear interest at a rate based upon the LIBOR Rate and Agent shall
have

 

4

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

the right to convert the interest rate on all outstanding LIBOR Rate Loans to
the rate then applicable to Advances that are Base Rate Loans hereunder.

(b) LIBOR Election.

(i) Administrative Borrower may, at any time and from time to time, so long as
no Event of Default has occurred and is continuing, elect to exercise the LIBOR
Option by notifying Agent prior to 11:00 a.m. (California time) at least 3
Business Days prior to the commencement of the proposed Interest Period (the
“LIBOR Deadline”). Notice of Administrative Borrower’s election of the LIBOR
Option for a permitted portion of the Advances and an Interest Period pursuant
to this Section shall be made by delivery to Agent of a LIBOR Notice received by
Agent before the LIBOR Deadline, or by telephonic notice received by Agent
before the LIBOR Deadline (to be confirmed by delivery to Agent of a LIBOR
Notice received by Agent prior to 5:00 p.m. (California time) on the same day).
Promptly upon its receipt of each such LIBOR Notice, Agent shall provide a copy
thereof to each of the Lenders having a Revolver Commitment.

(ii) Each LIBOR Notice shall be irrevocable and binding on Borrowers. In
connection with each LIBOR Rate Loan, each Borrower shall indemnify, defend, and
hold Agent and the Lenders harmless against any loss, cost, or expense incurred
by Agent or any Lender as a result of (a) the payment of any principal of any
LIBOR Rate Loan other than on the last day of an Interest Period applicable
thereto (including as a result of an Event of Default), (b) the conversion of
any LIBOR Rate Loan other than on the last day of the Interest Period applicable
thereto, or (c) the failure to borrow, convert, continue or prepay any LIBOR
Rate Loan on the date specified in any LIBOR Notice delivered pursuant hereto
(such losses, costs, or expenses, “Funding Losses”). Funding Losses shall, with
respect to Agent or any Lender, be deemed to equal the amount determined by
Agent or such Lender to be the excess, if any, of (i) the amount of interest
that would have accrued on the principal amount of such LIBOR Rate Loan had such
event not occurred, at the LIBOR Rate that would have been applicable thereto,
for the period from the date of such event to the last day of the then current
Interest Period therefor (or, in the case of a failure to borrow, convert or
continue, for the period that would have been the Interest Period therefor),
minus (ii) the amount of interest that would accrue on such principal amount for
such period at the interest rate which Agent or such Lender would be offered
were it to be offered, at the commencement of such period, Dollar deposits of a
comparable amount and period in the London interbank market. A certificate of
Agent or a Lender delivered to Administrative Borrower setting forth any amount
or amounts that Agent or such Lender is entitled to receive pursuant to this
Section 2.17 shall be conclusive absent manifest error.

(iii) Borrowers shall have not more than 5 LIBOR Rate Loans in effect at any
given time. Borrowers only may exercise the LIBOR Option for LIBOR Rate Loans of
at least $500,000 and integral multiples of $100,000 in excess thereof.

(c) Prepayments. Borrowers may prepay LIBOR Rate Loans at any time; provided,
however, that in the event that LIBOR Rate Loans are prepaid on any date that is
not the last day of the Interest Period applicable thereto, including as a
result of any automatic prepayment through the required application by Agent of
proceeds of Borrowers’ and their Subsidiaries’ Collections in accordance with
Section 2.4(b) or for any other reason, including

 

5

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

early termination of the term of this Agreement or acceleration of all or any
portion of the Obligations pursuant to the terms hereof, each Borrower shall
indemnify, defend, and hold Agent and the Lenders and their Participants
harmless against any and all Funding Losses in accordance with clause (b)(ii)
above.

(d) Special Provisions Applicable to LIBOR Rate.

(i) The LIBOR Rate may be adjusted by Agent with respect to any Lender on a
prospective basis to take into account any additional or increased costs to such
Lender of maintaining or obtaining any eurodollar deposits due to changes in
applicable law occurring subsequent to the commencement of the then applicable
Interest Period, including changes in tax laws (except changes of general
applicability in corporate income tax laws) and changes in the reserve
requirements imposed by the Board of Governors of the Federal Reserve System (or
any successor), excluding the Reserve Percentage, which additional or increased
costs would increase the cost of funding loans bearing interest at the LIBOR
Rate. In any such event, the affected Lender shall give Administrative Borrower
and Agent notice of such a determination and adjustment and Agent promptly shall
transmit the notice to each other Lender and, upon its receipt of the notice
from the affected Lender, Administrative Borrower may, by notice to such
affected Lender (y) require such Lender to furnish to Administrative Borrower a
statement setting forth the basis for adjusting such LIBOR Rate and the method
for determining the amount of such adjustment, or (z) repay the LIBOR Rate Loans
with respect to which such adjustment is made (together with any amounts due
under Section 2.17(b)(ii)).

(ii) In the event that any change in market conditions or any law, regulation,
treaty, or directive, or any change in the interpretation or application
thereof, shall at any time after the date hereof, in the reasonable opinion of
any Lender, make it unlawful or impractical for such Lender to fund or maintain
LIBOR Rate Loans or to continue such funding or maintaining, or to determine or
charge interest rates at the LIBOR Rate, such Lender shall give notice of such
changed circumstances to Agent and Administrative Borrower and Agent promptly
shall transmit the notice to each other Lender and (y) in the case of any LIBOR
Rate Loans of such Lender that are outstanding, the date specified in such
Lender’s notice shall be deemed to be the last day of the Interest Period of
such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans of such Lender
thereafter shall accrue interest at the rate then applicable to Advances that
are Base Rate Loans, and (z) Borrowers shall not be entitled to elect the LIBOR
Option until such Lender determines that it would no longer be unlawful or
impractical to do so.

(e) No Requirement of Matched Funding. Anything to the contrary contained herein
notwithstanding, neither Agent, nor any Lender, nor any of their Participants,
is required actually to acquire eurodollar deposits to fund or otherwise match
fund any Obligation as to which interest accrues at the LIBOR Rate. The
provisions of this Section shall apply as if each Lender or its Participants had
match funded any Obligation as to which interest is accruing at the LIBOR Rate
by acquiring eurodollar deposits for each Interest Period in the amount of the
LIBOR Rate Loans.

Amendment and the Credit Agreement, as amended hereby, are legal, valid and
binding obligations of each Borrower, enforceable against each Borrower in

counterparts, all of which when taken together shall constitute one and the same
instrument, and any of the parties hereto may execute this Fifth Amendment by

waiver of any right, power, or remedy of Agent or any Lender under the Credit
Agreement or any other Loan Document. The waivers, consents, and modifications
herein are limited to the specifics hereof, shall not apply with respect to any
facts or occurrences other than those on which the same are based, shall not
excuse future non-compliance with the Loan Documents, and shall not operate as a
consent to any further or other matter under the Loan Documents.

in the Credit Agreement to “this Agreement”, “hereunder”, “herein”, “hereof” or
