Gentlemen:

         Reference the Form SB-2 Registration  Statement of Assure Data, Inc. As
disclosed in the "Use of Proceeds"  section,  this will evidence our  commitment
that,  in the event the proceeds of the offering are  insufficient  to cover the
estimated offering costs of approximately $50,000, the undersigned hereby commit
and  agree to  contribute  to the  Company  sufficient  funds to cover  all such
offering costs.

         In addition,  the  undersigned  commit and agree that, in the event the
Company  experiences a deficit in its cash flow during the 12 months ending July
31, 2006, they will advance the Company sufficient funds to continue operations.
Any  such  loans  will  bear  interest  at the  annual  rate of 5%,  and will be
repayable upon demand.  No demand will be made unless the Company possesses cash
flow from  operations or third party  financings  such that repayment  would not
cause the Company to be unable to meet its foreseeable obligations.
