2.1	The License Deed is hereby amended whereby the Licensee’s use is governed by the following provisions;

(a)

The parties agree that the Territory does not include any countries or territories in North, Central or South America.

(b)

That Clause 2 above is without prejudice to Licensee's right under the License Deed to Use the CCS Technology and the Licensed Marks, but supersedes Licensee's right to sublicense the CCS Technology or the Licensed Marks and its right to assign its rights under the License Deed as further set forth in this Clause 2.1.

In addition, Licensee shall notify DBEL and DHI in writing immediately upon Licensee or EESTech Inc. being adjudicated bankrupt, going into liquidation, receivership or trusteeship voluntarily or otherwise, or voluntarily entering into any similar proceedings for the relief of debtors (each a "Bankruptcy Event").

(e)

Integrated CCS Technology shall not be included in the CCS Technology licensed to Licensee pursuant to the License Deed, and Licensee shall only have the right to use the Integrated CCS Technology in the Territory to the extent that such technology is embodied in the results of services provided by Licensor to Licensee where Licensor is Licensee's exclusive engineering partner or services provider and solely in connection with the specific project to which Licensor's services relate. Licensee shall not assign or sublicense such rights except for such assignments or sublicenses that would otherwise be permitted under Clause 2.1(d) of this Deed of Amendment.

3.	Licensor and Licensee further agree as follows:

3.1	Licensor agrees to enter into a royalty sharing agreement with Licensee whereby a portion of royalties received by Licensor from DBEL and DHI for Use of the CCS Technology in the Territory will be paid by Licensor to Licensee, based on the following formula:

Total royalties received by Licensor from DBEL / DHI for Use of the CCS Technology in the Territory, minus 2.45% of royalty bearing supply cost x 30%.

For greater clarification the following is an example of a project transaction occurring in the next 10-year period:

Royalty bearing CCS supply cost for a project based on a $200 mm capex.

Royalty of 6% = $12 million - (2.45% of $200 million) = $7.1 million x 30% = $2.13 million allocation to Licensee.

3.2	Licensor agrees to immediately effect the tax efficient delivery of five million (5,000,000) shares of EESTech Inc. to Licensee after Licensor, DBEL and DHI execute the Doosan License.

3.3	Notwithstanding anything to the contrary set forth in the Service Agreement by and between the parties dated as of November 29, 2007 (the "Services Agreement"), Licensor shall remain the exclusive provider to Licensee of the CSS Services, as defined in the Services Agreement.

3.4

Except as set forth above, the License Deed shall remain in full force and effect in accordance with its terms following the execution of this Deed of Amendment. This Deed of Amendment will be binding upon, and enforceable against, any permitted successors and assigns of Licensee. In the event of any conflict between the terms of this Deed of Amendment and the License Deed, the terms of this Deed of Amendment shall take precedence.

3.7	This Deed of Amendment is conditional upon the Licensor and DBEL and DHI entering into the Doosan License, and shall become effective upon written notification by Licensor to Licensee that the Doosan License has been executed.
