Grantor agrees to assemble the Collateral if Trustee so requires, and to make the Collateral available to Trustee at a place that Trustee may designate which is reasonably convenient to both parties.

secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and Grantor’s rights under all licenses and all franchise agreements shall inure to the Trustee and the Noteholders’ benefit;

(e) sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Grantors’ premises) as Trustee determines is commercially reasonable. It is not necessary that the Collateral be present at any such sale;

(f) Trustee shall give notice of the disposition of the Collateral as follows:

(i) Trustee shall give Grantor a notice in writing of the time and place of public sale, or, if the sale is a private sale or some other disposition other than a public sale is to be made of the Collateral, the time on or after which the private sale or other disposition is to be made; and

(ii) The notice shall be personally delivered or mailed, postage prepaid, to Grantor as provided in Section 6.4, at least 10 days before the earliest time of disposition set forth in the notice; no notice needs to be given prior to the disposition of any portion of the Collateral that is perishable or threatens to decline speedily in value or that is of a type customarily sold on a recognized market;

(i) The Trustee and Noteholders shall have all other rights and remedies available to them at law or in equity pursuant to any other Noteholder Documents; and

(j) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Grantor. Any excess will be returned, without interest and subject to the rights of third Persons, by Trustee to Grantor.

SECTION 5.2. Remedies Cumulative. The rights and remedies of the Trustee under this Agreement, the other Noteholder Documents and all other agreements are cumulative. The Trustee shall have all other rights and remedies not inconsistent with the Noteholder Documents as provided under the Code, by law, or in equity. No exercise by the Trustee of one right or remedy shall be deemed an election, and no waiver by the Trustee of any Event of Default shall be deemed a continuing waiver. No delay by the Trustee shall constitute a waiver, election, or acquiescence by it.

SECTION 5.3. Expenses. The Grantor will, upon demand, pay to the Trustee the amount of any and all reasonable expenses, including the reasonable fees and disbursements of its counsel and of any experts and agents, which the Trustee may incur in connection with (i) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any of the Collateral and (ii) the exercise or enforcement of any of the rights of the Trustee or the Noteholders under the Noteholder Documents.
