EXHIBIT 10.2




FIRST AMENDMENT TO STOCK SALE AGREEMENT




     THIS FIRST AMENDMENT TO STOCK SALE AGREEMENT (this “Amendment”), dated as of August 23, 2009,
is by and among AVASTRA SLEEP CENTRES LIMITED f/k/a Avastra, Ltd., an Australian corporation
(“Parent”), AVASTRAUSA, INC., a Delaware corporation (“Seller”), and SDC HOLDINGS, LLC, an Oklahoma
limited liability company (“Buyer”).



     A. Parent, Seller and Buyer are parties to that certain Stock Sale Agreement, dated August 19,
2009, pursuant to which Buyer will acquire the Somni Stock and the Eastern Stock (the “Agreement”).



     B. The parties desire to amend the Agreement as set forth in this Amendment.



     C. Capitalized terms used in this Amendment unless otherwise defined in this Amendment shall
have the meaning given such terms in the Agreement.



     NOW, THEREFORE, in consideration of the premises, and the mutual representations, warranties,
covenants and agreements hereinafter set forth, the parties agree as follows



     1. Section 6(a) of the Agreement. The parties agree that the provisions of Section 6(a) of the
Agreement are hereby replaced with the terms of Section 4 hereof to the extent, and only to the
extent, such provisions apply to the Somni Entities. Prior to the closing of the acquisition of the
Eastern Stock, the parties shall enter into a second amendment to the Agreement to replace the
terms of Section 6(a) with respect to the Eastern Entity on substantially the same terms as this
Amendment. No party shall be obligated to consummate the closing of the sale and acquisition of the
Eastern Stock unless such second amendment has been executed.



     2. Section 2(b) of the Agreement. Section 2(b) of the Agreement is amended to
read, in full, as follows:




“The closing of the sale of the Eastern Interests shall take place at the Closing
Location at 10:00 a.m. CDT on September 30, 2009 or such other earlier date as
designated by Buyer by providing Seller and Parent at least five (5) business days

prior written notice.”



     3. Section 3(a) of the Agreement. Section 3(a) of the Agreement is amended to change the
dollar amount of “US$6,000,000” to “US$5,900,000.” Otherwise, Section 3(a) of the Agreement remains
unchanged.



     4. Assumptions Regarding the Condition of the Somni Entities. The following is a
list of assumptions made by Buyer in determining the Purchase Price for the Somni Entities



1









 







(collectively, the “Assumptions”). If any of the Assumptions prove to be inaccurate, Buyer shall
have a claim, for the damages actually incurred by Buyer as a result of the particular Assumption
being inaccurate, solely as follows:



     (i) against Seller and only for a period of eighteen (18) months following closing of the
sale and purchase of the Somni Stock. Furthermore, Seller’s maximum aggregate liability for
all such claims shall be $3,000,000; and



     (ii) against Parent for a period of one (1) year following the closing of the sale and purchase
of the Somni Stock and solely to the extent of the Graymark Healthcare, Inc. common stock delivered
to Parent in connection with the closing of the acquisition of the Eastern Stock (the “Graymark
Stock”) as described in Section 3(b)(iii) of the Agreement. Notwithstanding the one year limitation
described immediately above, the parties agree that, after such one year period, a claim may be
brought for an Assumption being proven to be inaccurate against the Parent for an additional period
of six (6) months, but only to the extent of the Graymark Stock which is no longer subject to any
prohibition on transfer as set forth in Section 3(b)(iii) of the Agreement. For purposes of
illustration, the parties intend that on the first day of the first month following the one-year
anniversary of the closing of the sale and purchase of the Somni Stock that only seventy-five
percent (75%) of the Graymark Stock issued to Parent shall be subject to claims under the
Agreement, as amended, and that on the first day of the fourth month following the one-year
anniversary of the closing of the sale and purchase of the Somni Stock, that only fifty percent
(50%) of the Graymark Stock issued to Parent shall be subject to claims under the
Agreement, as amended.



     The parties further agree that no claim may be brought, for any Assumption being proven to be
inaccurate, regardless of the amount of the claim, against any of Parent’s officers or directors,
or the administrators of Parent, or any of the officers or directors of Seller. In addition, the
accuracy of the Assumptions shall be a condition precedent to Buyer’s obligation to close on the
acquisition of the Somni Stock. The remedies described in this Section 4 shall be the sole and
exclusive remedy with respect to any and all claims of an Assumption being proven to be inaccurate
To the extent this Section 4 is inconsistent with the provisions of Section 6(b) of the Agreement,
the provisions of this Section 4 shall prevail.



          (a) Authorization. The execution and delivery of the Agreement, the performance by Seller and
Parent of their obligations under the Agreement and the consummation by Seller and Parent of the
transactions contemplated by the Agreement (i) have been duly authorized by all requisite corporate
action on the part of Seller and Parent, and (ii) do
not violate any applicable law.




          (b) Authority. Each of the Sonmi Entities has all necessary power and authority to own,
operate or lease the assets now owned, operated or leased by it and to carry on the their business

incorporation or bylaws) and is transferring all such capital stock to Buyer pursuant to the
Agreement; provided, however, Buyer is aware that the failure to close and fund all amounts owed

Pamela R Gillis Revocable Trust (and related security and pledge documents) prior to 5:00 p.m. CDT
on August 24, 2009 could trigger certain rights that would affect the ownership of the Somni Stock
and/or the capitalization of the Somni Entities and would result in liens related to such Somni
Stock not being released.



          (e) Minute Books. The minute book of each of the Somni Entities contains accurate records of
all meetings and accurately reflects all other actions taken by the holders of capital stock of

accruals) that are necessary to present fairly in all material respects the financial condition of
