THIRD FORBEARANCE AGREEMENT

This Third Forbearance Agreement (herein, the “Third Forbearance Agreement”) is made as of this 3rd day of March, 2011, by and among Sbarro, Inc., a New York corporation (the “Borrower”), Sbarro Holdings, LLC, a Delaware limited liability company (“Holdings”), the Lenders (as defined in the Credit Agreement) party hereto and Bank of America, N.A., as Administrative Agent.

RECITALS:

A. The Lenders have extended credit to the Borrower on the terms and conditions set forth in that certain Credit Agreement dated as of January 31, 2007, as amended or otherwise modified prior to the date hereof, by and among the Borrower, Holdings, the Lenders, the Administrative Agent and the other entities party thereto (the “Credit Agreement”).

B. The Borrower has informed the Lenders that it is not in compliance with Section 7.16 of the Credit Agreement for the four fiscal quarter period ending January 2, 2011 (the “Financial Covenant Default”) (and the parties hereto acknowledge and agree that the date of December 26, 2010 set forth in such Section is a mistake and the correct date is January 2, 2011).

C. The Borrower has also informed the Lenders that it has failed to make the interest payment in respect of its Senior Notes that was due and payable on February 1, 2011, and that, beginning on March 3, 2011, such failure will constitute (i) an Event of Default under Section 8.01(e)(i)(A) of the Credit Agreement and (ii) an Event of Default under Section 8.01(e)(i)(A) of the Second Lien Credit Agreement, which will constitute an additional Event of Default under Section 8.01(e)(i)(A) of the Credit Agreement (such Events of Default, the “Cross-Defaults”).

D. The Lenders are not willing to waive the Event of Default that exists as a result of the Financial Covenant Default or the Events of Default that will exist beginning on March 3, 2011 as a result of the Cross-Defaults.

E. The Borrower has also informed the Lenders that it received a “Notice of Default” under the Senior Notes Indenture from a holder of the Senior Notes on December 28, 2010 with respect to the entry of the Second Lien Credit Agreement by the Loan Parties in March 2009 (the “Indenture Default Notice”) and that the Borrower disputes the defaults specified in the Indenture Default Notice.

F. The Borrower has requested that the Lenders temporarily forbear from exercising certain rights and remedies under the Loan Documents.

G. The Borrower, Holdings, the Lenders party thereto and the Administrative Agent have entered into (i) that certain Forbearance Agreement dated as of January 3, 2011 (the “First Forbearance Agreement”) and (ii) that certain Second Forbearance Agreement dated as of January 31, 2011 (the “Second Forbearance Agreement”).

H. In order to accommodate the Borrower’s request, during and only during the period (the “Standstill Period”) beginning on the date of this Third Forbearance Agreement and ending on the Standstill Termination Date (as defined below), the Lenders are willing to temporarily forbear from exercising their rights and remedies available solely by reason of the Financial Covenant Default, the Cross-Defaults or the delivery of the Indenture Default Notice on the terms, conditions, and provisions contained in this Third Forbearance Agreement.

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

1. Incorporation of Recitals; Defined Terms. Holdings, the Borrower and each of the Lenders party hereto acknowledges that the Recitals set forth above are true and correct in all material respects. The defined terms in the Recitals set forth above are hereby incorporated into this Third Forbearance Agreement by reference. All other capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Credit Agreement.

2. Confirmation by the Borrower of Loans and Letters of Credit. The Borrower acknowledges and agrees that as of March 1, 2011, the respective aggregate outstanding principal balances of the Loans and the aggregate face amount of outstanding Letters of Credit were as follows:

The Borrower acknowledges and agrees that as of (and including) March 1, 2011: (i) the aggregate amount of accrued and unpaid interest on the Revolving Loans and Term B Loans is $2,023,269.46, (ii) the aggregate amount of accrued and unpaid Letter of Credit Fees payable pursuant to Section 2.11(b) of the Credit Agreement is $27,449.32 and (iii) the foregoing amounts do not include other fees, expenses and other amounts which are chargeable or otherwise reimbursable under the Credit Agreement and the other Loan Documents. All of the foregoing amounts are the bona fide obligations of the Borrower, and the Borrower acknowledges its obligation to pay such amounts in accordance with the terms of the Credit Agreement and agrees that it has no right of setoff, defenses, claims or counterclaims with respect thereto.

3. Acknowledgment of Default. The Financial Covenant Default constitutes as of January 2, 2011, and each Cross-Default will constitute as of March 3, 2011, an Event of Default under the Credit Agreement (such Events of Default, the “Specified Events of Default”). The Borrower acknowledges that, as a result of the Specified Events of Default, (i) the conditions precedent to the obligation of each Lender to make Loans to the Borrower and to the obligation of each L/C Issuer to issue (or renew or extend the term of) any Letter of Credit set forth in Section 4.02 of the Credit Agreement are not satisfied and (ii) the Lenders are permitted and entitled under Section 8.02 of the Credit Agreement to terminate the Commitments, to accelerate

-2-

the Loans, to require cash collateral for L/C Obligations, to enforce Liens granted under the Collateral Documents and to exercise any other rights or remedies that may be available under the Loan Documents or under applicable law. Each of Holdings and the Borrower represents to the Administrative Agent and the Lenders that no Default or Event of Default exists other than the Specified Events of Default. Each of Holdings and the Borrower acknowledges that as a result of the Specified Events of Default, it is prohibited from taking any actions that would be otherwise permitted under the Credit Agreement that are conditioned upon no Default or Event of Default having occurred and being continuing (or words of similar import), and agrees not to take, and not to permit any of its respective Subsidiaries to take, any such actions. Furthermore (and without limiting the foregoing), each of Holdings and the Borrower acknowledges and agrees that as a result of the Specified Events of Default:

4. Forbearance. Until the Standstill Termination Date (as defined below) occurs, the Lenders will not (i) accelerate the Loans or enforce any of the Liens granted under the Collateral Documents solely as a result of the Specified Events of Default or the delivery of the Indenture Default Notice or (ii) exercise any other rights or remedies under the Loan Documents available solely by reason of the Specified Events of Default or the delivery of the Indenture Default Notice.

5. Certain Covenants. Each of Holdings and the Borrower hereby covenants and agrees with the Administrative Agent and the Lenders as follows:

6. Standstill Termination Date. As used in this Third Forbearance Agreement, “Standstill Termination Date” shall mean the earliest of (i) April 1, 2011, (ii) the date on which any Event of Default under the Credit Agreement other than the Specified Events Default shall occur, (iii) the date on which any breach by Holdings or the Borrower of any of the covenants set forth in Section 5 of this Third Forbearance Agreement shall occur (or, in the case of the covenants set forth in clauses (f) and (i) of such Section 5, the date that is two calendar days following any breach thereof unless such breach has been remedied on or prior to such date), (iv) the date on which the holders of the Senior Notes or the trustee under the Senior Note Indenture shall (a) accelerate obligations under the Senior Notes pursuant to Section 6.02 of the Senior Notes Indenture or (b) exercise any available remedy at law or in equity before a court of competent jurisdiction to collect the payment of obligations under the Senior Notes or to enforce the performance of any provision of the Senior Notes or the Senior Notes Indenture pursuant to Section 6.03 of the Senior Notes Indenture and (v) the date on which the Second Lien Lenders, the administrative agent or the collateral agent under the Second Lien Loan Documents shall (a) accelerate obligations under the Senior Lien Credit Agreement pursuant to Section 8.02(b) of the Second Lien Credit Agreement or (b) enforce any rights and interests created and existing under the Second Lien Loan Documents pursuant to Section 8.02(d) of the Second Lien Credit Agreement. The occurrence of the Standstill Termination Date shall be deemed an Event of Default under the Credit Agreement. Upon the occurrence of the Standstill Termination Date, the Standstill Period shall automatically terminate and the Lenders shall, at any time thereafter, be permitted and entitled under Section 8.02 of the Credit Agreement to, among other things, terminate the Commitments, accelerate the Loans, require cash collateral for L/C Obligations, enforce the Liens granted under the Collateral Documents and exercise all other rights and remedies available under the Loan Documents or applicable law.

7. No Waiver and Reservation of Rights. Each of Holdings and the Borrower acknowledges and agrees, on behalf of itself and on behalf of its respective Subsidiaries, that the Lenders are not waiving the Specified Events of Default (or any other Default or Event of Default), but are simply agreeing to forbear from exercising their rights with respect to the Specified Events of Default or the delivery of the Indenture Default Notice to the extent expressly set forth in this Third Forbearance Agreement. Without limiting the generality of the foregoing, each of Holdings and the Borrower acknowledges and agrees that immediately upon expiration of the Standstill Period, the Administrative Agent and the Lenders have all of their rights and remedies with respect to the Specified Events of Default or the delivery of the Indenture Default Notice to the same extent, and with the same force and effect, as if the

-6-

forbearance provided for herein had not been granted. Each of Holdings and the Borrower agrees not to assert and hereby forever waives, on behalf of itself and on behalf of its respective Subsidiaries, any right to assert that the Administrative Agent or the Lenders are obligated in any way to continue beyond the Standstill Period to forbear from enforcing their rights or remedies or that the Administrative Agent and the Lenders are not entitled to act on the Specified Events of Default or the delivery of the Indenture Default Notice on and after the occurrence of the Standstill Termination Date as if such Event of Default had just occurred and the Standstill Period had never existed. Each of Holdings and the Borrower acknowledges and agrees, on behalf of itself and on behalf of its respective Subsidiaries, that the Lenders have made no representations as to what actions, if any, the Lenders will take after the Standstill Period or upon or after the occurrence of the Standstill Termination Date, and the Lenders and the Administrative Agent do hereby specifically reserve any and all rights, remedies, and claims they have (after giving effect hereto) with respect to the Specified Events of Default or the delivery of the Indenture Default Notice and each other Default or Event of Default that may occur.

8. Loan Documents Remain Effective. Except as expressly set forth in this Third Forbearance Agreement, the Loan Documents and all of the obligations of Holdings and the Borrower thereunder, the rights and benefits of the Administrative Agent and Lenders thereunder, and the Liens created thereby remain in full force and effect. Without limiting the foregoing, each of Holdings and the Borrower agrees to comply with all of the terms, conditions, and provisions of the Loan Documents. This Third Forbearance Agreement and the Loan Documents are intended by the Lenders party hereto as a final expression of their agreement and are intended as a complete and exclusive statement of the terms and conditions of that agreement.
