Dear, James Koo

Attached is an accepted copy of your Purchase Security Agreement for the Code Grail Software.

Under the Agreement, this contract is non-cancelable during the term of the contract. The balance, however, can be paid off at any time prior to the expiration of the contract.

We would like to take this opportunity to express our appreciation for your business. If you have any questions concerning your contract, or if we can be of service to you in any way, please let us know.
