WITNESSETH:

WHEREAS, Pledgor is the owner of one hundred percent (100%) of the ownership interest in H & H OF VANDALIA LLC, an Ohio limited liability company (the “Interest”), which Interest is to be pledged to Pledgee; and

WHEREAS, Pledgor has executed and delivered to Pledgee a Promissory Note of even date herewith in the original principal amount of Three Million Six Hundred Thousand Dollars ($3,600,000) (the “Note”) evidencing certain obligations due to Pledgee as set forth therein between Pledgor and Pledgee (the “Loan”); and

WHEREAS, it is a condition precedent and material inducement to the credit extended and represented by the Note that Pledgor shall have executed and delivered this Agreement to Pledgee granting a continuing security interest to Pledgee in the Interest to secure the obligations of Pledgor to Pledgee.

NOW, THEREFORE, in consideration of the above, the parties hereto agree as follows:

1. Pledge. Pledgor hereby pledges, assigns and delivers to Pledgee by blank Assignment of Membership Interest, the Interest, and grants to Pledgee a first lien thereon and perfected first security interest therein and in all certificates, units, options, rights and other noncash distributions issued in addition to, in substitution or exchange for, or on account of the Interest(collectively, the “Collateral”). Pledgee shall have all of the rights, remedies and recourses with respect to the Collateral afforded to a secured party under the Uniform Commercial Code, in addition to any other rights, remedies, and recourses afforded to Pledgee by this Agreement. Pledgee shall hold the Collateral as security for Pledgor’s obligations to Pledgee pursuant to the Note.

2. Dividends and other Distributions With Respect to the Interest. If, while this Agreement is in effect, Pledgor shall become entitled to receive or shall receive (i) any unit or certificate or other security representing a dividend or other noncash distribution with respect to the Interest (including without limitation any certificate or other security issued in connection with a reclassification, increase or reduction of capital or issued in connection with any reorganization of the entity in which the Interest is held by Pledgor), or (ii) any option or rights, whether in addition to, in substitution of, or in exchange for any of the Interest, or otherwise, Pledgor agrees to accept the same as Pledgee’s agent and to hold the same in trust on behalf of and for the benefit of Pledgee in the exact form received, with the endorsement by Pledgor when necessary and/or appropriate of undated assignment of membership interest duly executed in blank, to be held by Pledgee subject to the terms hereof as

All sums of money and property so paid or distributed in respect of the Interest which are received by Pledgor shall, until paid or delivered to Pledgee, be held by Pledgor in trust as additional Collateral.

(a) Declare the entire balance of principal and accrued interest on the Note immediately due and payable; and

(b) Proceed to exercise all rights with respect to the Collateral of a secured creditor under the Uniform Commercial Code as adopted in the State of Ohio, including, without limitation, rights to liquidate and sell the Collateral at public or private sale, in any commercially reasonable manner. At any such sale, the Collateral may be sold in whole, or in part, by single or separate contracts, and upon such terms and conditions as Pledgee deems appropriate in the circumstances. Unless the Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market, reasonable notification of the time and place of any public sale or reasonable notification of the time after which any private sale or other intended disposition is to be made shall be sent by Pledgee to Pledgor at the address designated in Paragraph 9, unless Pledgor has signed after default a statement renouncing or modifying its right to notification of sale. For this purpose, notification shall be deemed reasonable if given in the manner provided in Paragraph 9, at least ten (10) days prior to the day of any such sale. Pledgee shall be entitled to participate in the public sale and purchase the Collateral at any such sale on terms no less favorable than the highest qualified, competing bid from a third party. Pledgor’s rights shall further include, without limitation, the authority (hereby granted) to cause the Interest to be transferred into Pledgee’s own name, or the name of Pledgee’s nominee, and shall be entitled to exercise all rights and privileges in connection with said Interest by virtue of being the holder of record thereof. In this connection, Pledgor acknowledges that it has delivered to Pledgee a duly executed Assignment of Membership Interest in the form attached hereto as Exhibit A to convey the Interest to Pledgee upon the occurrence of an Event of Default which is not cured within any applicable grace periods. Pledgee shall not be liable for failure to collect or realize upon the Collateral security or any part thereof, or for any delay in so doing nor shall it be under any obligation to take any action whatsoever with regard thereto. Pledgee may exercise any and all right of conversion, exchange, subscription or any other rights, privileges or options pertaining to any of the Interest as if Pledgee was the absolute owner thereof, all without any liability on the part of Pledgee.

5

Upon enforcement of this Agreement following the occurrence of an Event of Default, any Interest or Interests or the net proceeds from the disposition thereof (after deducting all reasonable costs and expenses incurred by Pledgee in connection therewith or incurred in connection with the care and safekeeping of the Collateral) (and after the payment by Pledgee of any other amount required to be paid by any provision of law) shall be applied to the payment in whole or in part of the Note. Pledgee shall account for the surplus, if any, to the Pledgor. To the extent permitted by applicable law, the Pledgor waives all claims, damages and demands against Pledgee arising out of the repossession, retention or sale of the Interest, except for those arising out of the gross negligence or willful misconduct of Pledgee or the failure of Pledgee to comply with any express obligation hereunder to Pledgor including the accounting for the surplus, if any, to the Pledgor as contemplated by the immediately preceding sentence. All surplus funds, if any, shall be paid to such Persons as are entitled under applicable law. If the proceeds of sale are not sufficient to satisfy the unpaid principal and accrued interest under the Note and the expenses of sale, Pledgor shall remain liable for any deficiency.
