AMENDMENTS AND AGREEMENTS:

1. Incorporation of Recitals. Each of the above Recitals is expressly incorporated herein by reference and made a part hereof for all purposes.

2. Reaffirmation of Indebtedness. Each Obligor hereby acknowledges that the Loan Documents and the Indebtedness constitute the valid
and binding Indebtedness of such Obligor enforceable against such Obligor in accordance with their respective terms, and each Obligor hereby reaffirms its obligations under the Loan Documents. The Lenders entry into this Agreement or any of
the documents referenced herein, its negotiations with any Person with respect to any Loan Documents, its conduct of any analysis or investigation of any Collateral for the Indebtedness or any Loan Documents, its acceptance of any payment from any
Obligor or any other Person of any payments made prior to the date hereof, or any other action or failure to act on the part of the Lender shall not constitute (a) a modification of any Loan Document or (b) a waiver of any Default or Event
of Default under the Credit Agreement, including, without limitation, the Enumerated Defaults, or any waiver of any term or provision of any Loan Document.

3. Enumerated Defaults. The Borrower acknowledges, confirms and agrees that (i) since February 28, 2009, a Default Period exists and (ii) the Borrower has failed to comply with at
least the Enumerated Defaults, each of which presently constitutes an Event of Default and entitles the Lender to exercise its rights and remedies under the Credit Agreement and the other Loan Documents and other rights and remedies available under
applicable law.

4. Forbearance. The Lender hereby agrees to continue to forbear from the exercise of any of its rights
and remedies under Section 7.2 of the Credit Agreement and the other Loan Documents as a result of the Enumerated Defaults during the Forbearance Period; provided, however, that such forbearance shall be subject to all terms and conditions set
forth in this Agreement and nothing contained herein shall alter, affect or impair in any way the Lenders ability to exercise discretion as provided in the Credit Agreement or to exercise any other rights and remedies available to it
irrespective of whether a Default or Event of Default exists.

5. Forbearance Limited to Enumerated Defaults. The
Lenders forbearance shall be limited solely to the Enumerated Defaults existing on the date hereof and to the inapplicability of the covenants found in Sections 6.2(a) and 6.2(c) of the Credit Agreement during the Forbearance Period, and the
Lender shall not be deemed to have waived any rights or remedies it may have with respect to any other existing or future breach, Default or Event of Default arising or occurring thereunder during the Forbearance Period or with respect to any breach
of this Agreement.

6. Notice Requirements Satisfied. Each Obligor acknowledges that all notice
requirements embodied in the Loan Documents and imposed upon the Lender in connection with the Enumerated Defaults, and the exercise of its remedies therefor (together with all applicable cure and/or grace periods) have been satisfied (or shall be
deemed to have been satisfied by this Agreement) without exception, and that upon the expiration of the Forbearance Period, the Lender shall, with respect to the Enumerated Defaults, have the full right and power to exercise all remedies granted to
it thereunder without further notice to the Obligors or any of them and subject to no other conditions precedent.

7.
Agreement in the Nature of Forbearance Only. Each Obligor hereby acknowledges that the Lenders obligations under this Agreement are in the nature of a conditional forbearance only, and that the Lender has made no agreement or commitment
to modify or extend the Loan Documents or to forbear beyond the Forbearance Period, and that, upon the termination of the Forbearance Period, the Lender shall have the immediate and unconditional right to exercise all of its rights and remedies
under the Loan Documents.

| | -- | -----------------------------------------------------------------------------------------------------------------------



| | b. | New Event of Default. The occurrence of any Default or Event of Default under any one or more of the Loan Documents other than the Enumerated Defaults. For
avoidance of doubt, a Default or Event of Default arising or occurring after the date hereof is not an Enumerated Default even though a prior breach thereof may have resulted in an Enumerated Default.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | Creditor Enforcement Action. Any creditor or creditors of any Obligor take or threaten any enforcement action (i.e., action under applicable law to foreclose,
execute or levy on, collect on, take possession of or control of, or sell or otherwise realize upon (whether judicially or non-judicially) or to lease, license or otherwise dispose of (whether publicly or privately) any assets of an Obligor or
otherwise to exercise or enforce remedial rights with respect to assets, to sue one or more of the Obligors, to seek or obtain a judgment against one or more of the Obligors, or to seek or commence, or join in the filing of a petition or complaint
seeking insolvency, bankruptcy, receivership, conservatorship or similar proceedings) that, in the Lenders sole and exclusive judgment, would materially interfere with the operation of the business of the Obligors or the Lenders ability
to collect the Indebtedness of the Obligors.

them, is a Default and an Event of Default. Upon termination of the Forbearance Period, the Lenders agreement to forbear shall terminate automatically without further act or action by the Lender, and the Lender shall be entitled to exercise
any and all rights and remedies available under the Loan Documents and this Agreement, at law, in equity, or otherwise without any further lapse of time, expiration of applicable grace periods, or requirements of notice, demand, presentment, notice
of dishonor, notice of acceleration, notice of intent to accelerate, notice of intent to foreclose, notice of sale, notice of protest or other formalities of any kind, all of which are hereby expressly waived by each Obligor.
