6. Representations by New Indemnitor.

a. Each New Indemnitor represents that the execution and delivery of this New Indemnitor Joinder, and performance by each New Indemnitor under the New Indemnitor Joinder and the Guaranty will not (i) violate any provision of any law, rule, regulation, order, writ, judgment, injunction, decree, determination or award presently in effect having applicability to New Indemnitor or (ii) result in a breach of or constitute or cause a default under any indenture, agreement, lease or instrument to which New Indemnitor is a party or by which the Project may be bound or affected.

b. Each of the TNP REIT and Thompson agrees to timely comply with all financial reporting or any other covenants or requirements relating to any guarantor of the Loan in any of the Loan Documents, including but not limited to those set forth in Section 6.3 of the Loan Agreement, as modified by the terms of the Agreement.

c. New Indemnitors represent and agree that, in the aggregate, New Indemnitor has and will maintain throughout the term of the Loan a Net Worth of at least Twenty Five Million Dollars and 00/100 ($25,000,000.00) (“Minimum Net Worth”). “Net Worth” shall mean, as of any date, the difference between (i) the total assets (not including the Project and not counting the value of the same assets more than once, i.e. the value of the TNP REIT’s interest in the TNP Operating Partnership and the value of the TNP Operating Partnership’s interest in New Borrower) of the Person (as such term is defined in the Loan Agreement) whose Net Worth is being determined that would appear on a balance sheet of such Person prepared as of such date in accordance with GAAP (as such term is defined in the Loan Agreement), and (ii) such Person’s total liabilities, including, without limitation, any obligations under direct or indirect guarantees and obligations (contingent or otherwise) to purchase or otherwise acquire, or otherwise to assure a creditor against loss, in either instance in respect of obligations of others, that would appear on a balance sheet of such Person prepared as of such date in accordance with GAAP. Failure of New Indemnitor to maintain the Minimum Net Worth at all times during the term of Loan shall constitute an Event of Default under the Loan Documents and the Guaranty.

d. New Indemnitor (other than Property Manager) acknowledges and agrees to the terms of Section 1.2(k) of the Agreement and further represents and warrants to Lender the following

(i) That the Key Bank Credit Facility is not secured by (a) all or any portion of the TNP Operating Partnership’s interest in New Borrower or any other assets of New Borrower, (b) a mortgage, deed of trust or other security interest in the Project, or (c) a pledge or any other direct or indirect security or other interest in the general partnership interest in the Operating Partnership, currently held by the TNP REIT;

(ii) That the Key Bank Credit Facility is secured by a pledge of no greater than a 49% interest of the TNP REIT’s limited partnership interests in the TNP Operating Partnership with no additional rights in the TNP Operating Partnership, including any right to profits or proceeds, other than those rights to which a 49% limited partner of the TNP Operating Partnership is entitled under the Limited Partnership Agreement of in the TNP Operating Partnership;

(iii) That the Project Manager is not a party to the Key Bank Credit Facility and has not provided any security or collateral therefore;

(iv) That in the event of a default by the Operating Partnership under the Key Bank Credit Facility, Key Bank has no right to directly or indirectly control the REIT, the Operating Partnership, the Project Manager or New Borrower;

(v) That in the event of a default by New Borrower under any of the Loan Documents, Key Bank has no right to consent to or approve any modifications to the Loan Documents in connection with a workout of the Loan or otherwise;

(vi) That there is no prohibition in the Key Bank Credit Facility Loan Documents that prohibits or restricts the TNP Operating Partnership or the TNP REIT from being a guarantor of the Loan, including, under certain circumstances, a guarantor of the entire principal balance of the Loan and all other sums due under the Loan Documents; and

e. The TNP REIT has immediately available funds to contribute to the Operating Partnership to contribute to New Borrower to purchase the Project and has not borrowed such funds from any Person.

New Indemnitor (other than Property Manager) acknowledges and agrees that any modifications or amendments to the terms of the Key Bank Facility which causes any of the foregoing statements to be untrue or incorrect without first obtaining the Lender written consent shall constitute an Event of Default under the Loan Documents and shall constitute a Springing Recourse Event under Section 10.1 of the Loan Agreement and Section 1(b) of the Guaranty. In addition, if any of the representations in this subsection (d) are untrue and incorrect as of the date hereof, it shall also constitute an Event of Default under the Loan Documents and a Springing Recourse Event under Section 10.1 of the Loan Agreement and Section 1(b) of the Guaranty.

f. Thompson represents that all of the assets shown on Thompson’s Financial Statements are community property assets under the laws of the State of California or owned by him individually as his separate property and were acquired during his marriage to his current spouse (and not during a period when they were living apart before a judgment of dissolution of marriage or legal separation of the parties). Thompson further represents that all of the assumptions (other than those relating to Lender) in that certain legal opinion issued by the Law Offices of Michael Sitzer to Lender, dated as of the date hereof, are true and correct. A breach of any of the representations made in this paragraph shall constitute a Springing Recourse Event under Section 10.1 of the Loan Agreement and Section 1(b) of the Guaranty, but solely with respect to Thompson.

7. Notices to New Indemnitor. From and after the Acquisition Date, Lender shall deliver any notices to New Indemnitor which are required to be delivered pursuant to the
