(b) The projections and pro forma financial information contained in the factual information referred to in clause (a) above (including the pro forma consolidated financial statements delivered hereunder) were or are based on good faith estimates and assumptions believed to be reasonable at the time made, it being recognized by Lender that such projections as to future events are not to be viewed as facts and that actual results during the period or periods covered by any such projections may differ significantly from the projected results.

Each Borrower will be solvent after consummation of the DPAC Transaction, and creation of the Obligations hereunder and under the Senior Loan Documents, the security interests of Lender, Senior Lender and the State of Ohio and the other transactions contemplated hereby and by the Senior Loan Documents.

Lender shall be named an additional named insured, lender loss payee and mortgagee on such insurance policies, as the case may be, to the extent that such policies insure the Collateral. In the event of any casualty for which the proceeds of insurance are less than Twenty Five Thousand and 00/100 Dollars ($25,000.00), however, the Borrowers shall be entitled to retain such proceeds for the purpose of repairing or replacing the insured property, provided that the Borrowers promptly execute and deliver to the Lender such documents, instruments, financing statements or other agreements as may be necessary to perfect the security interest of the Lender in all such property.
