|                |  |                              |  
|--------------- |  | ---------------------------- | -
|Period          |  | Percentage ofDirect Expenses |  
|1/2005-9/2005   |  | 48.70                        | %
|10/2005-12/2005 |  | 73.05                        | %
|1/2006-1/2015   |  | 100.00                       | %



In addition to the Sublessees
Share of Direct Expenses, Sublessee shall pay, for the entire period of the Sublease, 100% of all other expenses which Sublessor must pay directly or indirectly under the Lease including but not limited to utilities, janitorial, security,
maintenance and disposal of hazardous waste generated in the normal course of business. Reconciliation of the expenses shall be conducted at the end of each calendar year in accordance with Section 2(e) of the Lease.



5. Security. Sublessee shall provide Sublessor an initial security deposit in the form
of cash or a letter of credit in an amount equal to six months Base Rent based on the 2006 monthly rental rate, or $754,020.72, (the Security Deposit). Provided Sublessee has met its rental obligation during the first twelve months
of the Sublease, the Security Deposit shall be reduced to an amount equal to four months Base Rent based on the 2006 monthly rental rate, or $502,680.48. Provided Sublessee has met its rental obligation for an additional twelve months, the
Security Deposit shall be reduced to an amount equal to one months Base Rent based on the 2006 monthly rental rate or $125,670.12 (the Minimum Deposit) and Sublessee shall maintain a working capital balance of $25 Million (the
Balance). Should Sublessees working capital fall below the Balance in any given month following the reduction in Security Deposit to the Minimum Deposit, Sublessee must post a Security Deposit as follows:



| | a. | If Sublessee does not meet the Balance in the first three years after the Minimum Deposit is required, the Security Deposit shall be increased to an amount equal to six months
Base Rent at the prevailing rate.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | If Sublessee fails to the meet the Balance after the first three years after the Minimum Deposit is required, the Security Deposit shall be increased to an amount equal to three
months Base Rent at the prevailing rate.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

The Security Deposit will decrease to the Minimum Deposit after Sublessee has provided Sublessor evidence of maintaining
the Balance for four consecutive quarters. Should Sublessee use less than $750,000 to upfit the Premises, Sublessee shall post an additional amount as a security deposit. The amount of the additional security deposit shall equal the difference
between the actual amount spent for upfit and $750,000.
