The second investment consideration will be paid by KESC, subject to KESC and OOO Geostream Assets Management’s prior mutual agreement as set forth below,

(1) in a combination of the following:

(a)

Cash; and

(b)

A promissory note, issued by KESC in favor of OOO Geostream Services Group affiliate company, payable thirty (30) days after demand (“Promissory Note”), but not later than October 31, 2009, and subject to provisions to be set forth in the Promissory Note providing, among other things, that in the event that KESC fails to timely pay the balance due under the Promissory Note pursuant to the terms thereof, KESC shall be obligated within thirty (30) days to relinquish, transfer and assign to OOO Geostream Assets Management the number of Shares equal to:

(i) the total number of Shares issued to KESC in the Second Closing; multiplied by

Any such relinquishment, transfer and assignment to OOO Geostream Assets Management of Shares as described above shall be deemed payment in full satisfaction of the balance then due and payable under the Promissory Note and KESC shall thereafter be released of all covenants, liabilities and obligations under the Promissory Note.
