                       RESTRICTED STOCK PURCHASE AGREEMENT


        This RESTRICTED STOCK PURCHASE AGREEMENT (this "AGREEMENT") is made as
of this 31st day of March, 2006 (the "GRANT DATE"), between NBC Holdings Corp.,
a Delaware corporation (the "COMPANY"), and Alan Siemek (the "PURCHASER").

        WHEREAS, the Purchaser is an employee of the Company whose participation

        WHEREAS, the Company desires to sell to the Purchaser, and the Purchaser

        NOW, THEREFORE, in consideration of the promises and mutual covenants
herein set forth, and other good and valuable consideration, receipt of which is
hereby acknowledged, the parties hereto hereby mutually covenant and agree as
follows:

        1. RELATIONSHIP TO PLAN. This Agreement is entered into pursuant to the
Company's 2005 Restricted Stock Plan (the "PLAN"), and is in all respects,

        4. ISSUANCE OF CERTIFICATE FOR THE PURCHASED SHARES. Upon receipt by the
Company of full payment of the purchase price as described in Section 3, the
Company shall issue in the name of the Purchaser duly executed certificates
evidencing the Purchased Shares (the "CERTIFICATES"), which Certificates shall
be endorsed with the legends required under (i) the Stockholders Agreement,
dated as of March 4, 2004, by and among the Company and the Stockholders (as
such term is defined therein) (the "STOCKHOLDERS AGREEMENT"), (ii) the Stock
Repurchase Agreement, dated as of the date hereof, between the Company and the
Purchaser (the "REPURCHASE AGREEMENT") and (iii) the Plan. The Purchased Shares
shall be held in escrow in accordance with the terms of the Repurchase
Agreement.

        5. AGREEMENT TO ENTER INTO STOCKHOLDERS AGREEMENT AND REPURCHASE
AGREEMENT. The Purchaser agrees, to the extent not already a party thereto, to
become a party to the Stockholders Agreement by signing an instrument of
adherence to the Stockholders Agreement, and the grant of the Award and delivery
of the Certificates is made expressly conditioned on such execution by the
Purchaser of the Stockholders Agreement. The Purchaser agrees to execute and
deliver the Repurchase Agreement and the grant of the Award and delivery of the
Certificates is made expressly conditioned on such execution by the Purchaser of
the Repurchase Agreement.

        6. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.

        (a) The Purchaser hereby represents and warrants to the Company, its
officers, directors, agents, and employees as follows:

               (i) That the Purchaser has had an opportunity to ask questions of
and receive answers from the authorized representatives of the Company, and to
review any relevant documents and records concerning the business of the Company
and the terms and conditions of this investment, and that any such questions
have been answered to the Purchaser's full satisfaction.

               (ii) That the Purchaser has such knowledge and experience in
financial and business matters that the Purchaser is capable of evaluating the
merits and risks of an investment in the Company.

               (iii) That the Purchased Shares are being acquired for the
Purchaser's own account for investment and not with a view toward subdivision,
resale, or redistribution thereof in a manner prohibited under the Securities
Act of 1933, as amended (the "ACT"). Other than the Stockholders Agreement and
the Repurchase Agreement, the Purchaser has no contract, undertaking, agreement,
understanding, or arrangement with any person to sell, transfer, or pledge to
any person any part or all of the Purchased Shares for which the Purchaser
hereby subscribes, or any interest therein, and has no present plans to enter
into the same.

               (iv) That the Purchaser is an "ACCREDITED INVESTOR" as defined in
Regulation D of the Act by virtue of the Purchaser's being an executive officer
or director of the Company, if not otherwise.

               (v) That all information which the Purchaser has provided (or
will provide) concerning the Purchaser and the Purchaser's financial position,
is correct and complete as of the date of this Agreement.

        (b) The Purchaser acknowledges that the Company and its officers,
directors, employees, and agents are relying on the truth and accuracy of the
representations and warranties set forth in Section 6(a) in connection with the
offering of Purchased Shares for sale to the Purchaser without having first
registered the Purchased Shares under the Act. All representations, warranties,
and covenants contained in this Agreement shall survive the acceptance of this
Agreement and the sale of the Purchased Shares. Notwithstanding the foregoing,
however, no representation, warranty, acknowledgment, or agreement made herein
by the Purchaser shall in any manner be deemed to constitute a waiver of any
rights granted to the Purchaser under federal or state securities laws.

        7. INVESTMENT INTENT.

        (a) The parties agree that none of the Purchased Shares or any
beneficial interest therein shall be sold, transferred, assigned, pledged,
encumbered or otherwise disposed of in any way (including, without limitation,
by operation of law, except upon the death of Purchaser) unless and until (i)
such Purchased Shares or such beneficial interest, as the case may be, proposed
to be sold, transferred, assigned, pledged, encumbered or otherwise disposed of
are registered pursuant to an effective registration filed with the Securities
and Exchange Commission pursuant to the Act or (ii) if required by the Company,
the Company shall have received, at the Purchaser's expense, an opinion, in form
and substance satisfactory to the Company, from legal counsel satisfactory to
the Company to the effect that the sale, transfer, assignment, pledge,
encumbrance or other disposition of such Purchased Shares or such beneficial
interest, as the case may be, does not require registration under the Act or any
applicable state securities laws.

        (b) The Purchaser understands and agrees that neither the Company nor
any agent of the Company shall be under any obligation to recognize any transfer
of any of the Purchased Shares if, in the opinion of counsel for the Company,
such transfer would result in violation by the Company of any federal or state
law with respect to the offering, issuance or sale of securities.

        8. SECTION 83(B) ELECTION. The Purchaser has reviewed with the
Purchaser's own tax advisors the federal, state, local and foreign tax
consequences of this investment and the transactions contemplated by this
Agreement. The Purchaser is relying solely on such advisors and not on any
statements or representations of the Company or any of its agents. The Purchaser
hereby agrees to deliver to the Company a signed copy of any instrument, letter
or other document the Purchaser may execute and file with the Internal Revenue
Service evidencing the Purchaser's election under Section 83(b)(2) of the
Internal Revenue Code of 1986, as amended, to treat the Purchaser's receipt of
the Purchased Shares hereunder as includable in the Purchaser's gross income in
the year of receipt. The Purchaser shall deliver a copy of any such instrument
of election to the Company no later than the date on which any such election is
required to be made in accordance with the appropriate provisions of the
Internal Revenue Code or applicable Regulations thereunder. THE PURCHASER
ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE RESPONSIBILITY AND NOT THE
COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION 83(b), EVEN IF THE PURCHASER
REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON THE
PURCHASER'S BEHALF.
