This AMENDMENT NUMBER EIGHT TO CREDIT AGREEMENT (this “Amendment”) is entered into as of March 8, 2007, 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, Borrowers have requested that the Lender Group agree to certain amendments to the Credit Agreement, as set forth herein; and

WHEREAS, subject to the terms and conditions set forth herein, the Lender Group is willing to make the amendments requested by Borrowers, 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:

“(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 that is a Base Rate Loan, at a per annum rate equal to the Base Rate plus 2.50 percentage points, (ii) if the relevant Obligation is an Advance that is a LIBOR Rate Loan, at a per annum rate equal to the LIBOR Rate plus the Applicable Margin, and (iii) if the relevant Obligation is the Term Loan A, at a per annum rate equal to the Base Rate plus 2.50 percentage points.”

“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 be charged at a rate of interest based upon the LIBOR Rate.”

“(i) Minimum EBITDA. EBITDA, measured on a quarter-end basis, of at least the required amount set forth in the following table for the applicable period set forth opposite thereto:

“Agent shall, in its Permitted Discretion, establish the quarterly minimum EBITDA and Fixed Charge Coverage Ratio levels for each trailing 12 month period ending at the end of a quarter after December 28, 2008 based upon Borrowers’ Projections for such trailing 12 month period delivered pursuant to Section 5.3 of this Agreement, which Borrowers’ Projections shall be satisfactory to Agent in all respects. Borrowers shall execute any amendment to

2

this Section 6.16 reasonably requested by Agent to document the inclusion of such minimum EBITDA and Fixed Charge Coverage Ratio levels. If Borrowers fail to timely deliver the Projections required to be delivered pursuant to Section 5.3, the EBITDA and Fixed Charge Coverage Ratio levels shall be measured on a quarterly basis at an amount equal to 110% of the minimum EBITDA and Fixed Charge Coverage Ratio levels for the immediately preceding trailing 12 months.”

“(ii) Intentionally Omitted.”

““Applicable Margin” means, as of any date of determination (with respect to outstanding Advances on such date that are Base Rate Loans or LIBOR Rate Loans, as the case may be), the margins set forth in the following table that correspond to the most recent certified Leverage Ratio calculation delivered to Agent pursuant to Section 5.3 hereof; provided, however, that for the period from the Eighth Amendment Effective Date through the date Agent receives the certified calculation of the Leverage Ratio in respect of the “testing period” ending [April 1, 2007], the Applicable Margin shall be at the margin in the row styled “Level I”:

3

Except as set forth in the foregoing proviso, the Applicable Margin shall be based upon the most recent calculation of the Leverage Ratio, which will be calculated as of the end of each fiscal quarter. Except as set forth in the initial proviso in this definition, the Applicable Margin shall be re-determined each fiscal quarter on the first day of the fiscal quarter following the date of delivery to Agent of the certified calculation of the Leverage Ratio pursuant to Section 5.3; provided, however, that if Borrowers fail to provide such certification when such certification is due, the Applicable Margin shall be set at the margin in the row styled “Level I” as of the first day of the month following the date on which the certification was required to be delivered until the date on which such certification is delivered (on which date (but not retroactively), without constituting a waiver of any Default or Event of Default occasioned by the failure to timely deliver such certification, the Applicable Margin shall be set at the margin based upon the Leverage Ratio calculation disclosed by such certification. In the event that the information contained in any financial statement or Compliance Certificate delivered pursuant to the Agreement is shown to be inaccurate, and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for any period (an “Applicable Period”) than the Applicable Margin actually applied for such Applicable Period, then (i) Borrowers shall immediately deliver to Agent a correct Compliance Certificate for such Applicable Period, (ii) the Applicable Margin shall be determined as if “Level I” (as set forth in the table above) were applicable for such Applicable Period, and (iii) Borrowers shall immediately deliver to Agent full payment in respect of the accrued additional interest on the Obligations as a result of such increased Applicable Margin for such Applicable Period, which payment shall be promptly applied by Agent to the affected Obligations.”

““Borrowing Base” means, as of any date of determination, the result of:

(a) the lesser of

(i) the product of the 1.75 times TTM EBITDA for the most recently ended 12 consecutive monthly periods for which financial statements have been delivered pursuant to Section 5.3, and

(ii) 50% of the most recently determined Enterprise Value;

minus

(b) the sum of (i) the Bank Product Reserve, and (ii) the aggregate amount of reserves, if any, established by Agent under Section 2.1(b).”

““EBITDA” means, with respect to any fiscal period, in each case as determined in accordance with GAAP, Parent’s and its Subsidiaries’ consolidated net earnings (or loss), minus extraordinary gains and interest income for such period, plus:

(a) interest expense, income taxes, depreciation and amortization, and Restaurant Pre-Opening Expenses for such period;

(c) for any fiscal year after fiscal year 2004 through and including fiscal year 2006, charges not to exceed $1,000,000 (inclusive of legal fees and disbursements) in the aggregate for amounts, if any, in excess of the remaining reserve therefor paid during such period under the settlement of the Class Action Lawsuit;

(d) any non-cash asset impairment charges or fixed asset additions for restaurant properties that have previously been impaired, in each case in accordance with FASB 144 (to the extent having been deducted in the calculation of net earnings (loss) for such period);

(e) for the fourth fiscal quarter of fiscal year 2005 and each fiscal year thereafter, any charges related to FIN 47 in amount not to exceed $359,857 for the fourth fiscal quarter of fiscal year 2005 and $210,000 for each fiscal year thereafter; and

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH A CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM, MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.”

As to each and every claim released hereunder, each Borrower also waives the benefit of each other similar provision of applicable federal or state law (including without limitation the laws of the state of New York), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.
