The Index for the month in which the thirtieth (30/th/) day preceding each Adjustment Date falls shall be deemed the "Adjustment Index". The Adjustment Index for determining an adjustment to the Base NNN Rental for a specific Adjustment Date shall be deemed the Index on the next following Adjustment Date. At the Adjustment Date, the new Base NNN Rental shall be determined by multiplying the then current Base NNN Rental by the percentage increase of the Adjustment Index over the Index; provided, however, that in no event shall the Base NNN Rental as so adjusted be less than 103% nor more than 108% of the Base NNN Rental in effect for the month immediately prior to such Adjustment Date. When the new Base NNN Rental is determined, Sublessor shall give Sublessee written notice of same. If Sublessor fails to give timely notice of the new Base NNN Rental, the Adjustment shall be retroactive to the Adjustment Date and Sublessee shall pay the arrears within fifteen (15) days after being billed therefor. If at any Adjustment Date, the Index is no longer published as described in this section, Sublessor, after consultation with Sublessee, shall substitute the official index published by the United States Department of Labor, Bureau of Labor Statistics or successors or similar government agency as may then be in existence which is most nearly equivalent thereto. 6.1 SECURITY DEPOSIT The amount of $29,967.82 shall be paid upon execution of this Sublease as a non- interest bearing security for performance under this Sublease. If Sublessee fails to pay rent or other charges due hereunder, or otherwise defaults with respect to any provision of the lease, Sublessor may use, apply or retain all or any portion of said deposit for the payment of any rent or other charge in default for the payment of any other sum to which Sublessor may become obligated by reason of Sublessee's default, or to compensate Sublessor for any loss or damage which Sublessor may suffer thereby. If Sublessor so uses or applies all or any portion of said deposit, Sublessee shall within ten (10) days after written demand therefor, deposit cash with Sublessor in an amount sufficient to restore said deposit to the full amount required under this Sublease. In any event, the full amount of the security deposit shall be retained by Sublessor for the full Term hereof and within thirty (30) days following Sublessee's vacation of the Premises and Sublessor's inspection thereof, said deposit shall be returned to Sublessee, less any amounts due to compensate Sublessor for damage or defaults of Sublessee. 6.2 LETTER OF CREDIT Sublessee, at Sublessee's sole cost and expense, shall provide a letter of credit in the amount of $60,000.00 for the first two full years of the Sublease In the event Sublessee defaults, or has defaulted on any monetary obligation under this Sublease (Monetary Default) in the first two (2) years of the Term hereof, Sublessee shall maintain a letter of credit in the amount of $60,000.00 for a period extending two full years from the last date upon which Sublessee Monetary Default has occurred. The letter of credit shall be in the form of an irrevocable, unconditional, and clean letter of credit, payable at sight and upon demand, in form and substance acceptable to Sublessor in its sole and absolute discretion, from Citibank, N.A., Bank of America, N.A. or Wells Fargo Bank, N.A. or another 4 national bank acceptable to Sublessor with offices in San Francisco or Marin, County, California that will accept and pay on any draw on said letter of credit ("Letter of Credit"). The Letter of Credit shall designate Sublessor as beneficiary and shall be transferable by beneficiary to any transferee, successor, and assign (including any lender of Sublessor) at no cost or expense to beneficiary. The letter of credit shall be for a minimum period of two years Sublessor shall have the right to draw (in whole or in part) on the Letter of Credit any time it would otherwise have the right to apply all or any portion of the Security Deposit under the terms of the Sublease. However, the Letter of Credit shall provide that it may be drawn by Sublessor (or assignee) upon presentation by Sublessor to the issuing bank (at its offices in San Francisco or Marin, County, California) of a sight draft(s), together with a statement from Sublessor that the amount requested by Sublessor is due and owing to Sublessor and shall be payable by the bank without inquiry or any other documentation or further action required of the bank, Sublessor, or Sublessee. All costs and expenses to obtain the Letter of Credit and all renewals shall be borne by Sublessee. Notwithstanding the foregoing, in the event Sublessee has not been in default hereunder during the first two (2) full years of the Sublease Term, Sublessee's obligation to maintain a Letter of Credit for the benefit of Sublessor shall terminate. 7.1 TERM A.
