Fiscal Year; Organizational Documents; Material Contracts.
The Parent will not, nor will it permit any of its Subsidiaries to, change its fiscal year, except to adopt a retail fiscal year end which is no more than 65 days from December 31. The Borrower will promptly notify the Agent of such change in fiscal year. The Parent will not, nor will it permit any Subsidiary to, amend, modify or change its articles of incorporation (or corporate charter or other similar organizational document) or bylaws (or other similar document) in any manner that could adversely affect the rights of the Lenders hereunder. The Parent will not, nor will it permit any of its Subsidiaries to, without the prior written consent of the Administrative Agent, amend, modify, cancel or terminate or fail to renew or extend or permit the amendment, modification, cancellation or termination of any of the Material Contracts, except in the event that such amendments, modifications, cancellations or terminations could not reasonably be expected to have a Material Adverse Effect.
