 W I T N E S S E T H : 
 WHEREAS, the Company, through its subsidiary, PA, LLC, a Delaware limited liability company, f/k/a as PetroAlgae, LLC (the
“LLC”), is currently developing and commercializing certain oil-from-algae technologies, and EAD Constructors, Inc., a Nebraska corporation and wholly owned subsidiary of the Purchaser (“Constructors”) has been
retained by the LLC to assist the LLC in the design and engineering, and construction of facilities for the growth and harvesting of algae for the production of algae oil (the “Services”). 
 WHEREAS, the Company, the LLC, Constructors and Purchaser desire for the Company to issue to the Purchaser one hundred fifty-one thousand
fifty-seven (151,057) shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (the “Common Stock”) as partial consideration, partially in advance, for the Services (the “Stock
Purchase”), to be performed prior to June 30, 2009, as that term is defined or will be defined in the Services Agreement, by Constructors, in lieu of cash consideration (in part) for such Services. 
 WHEREAS, as of the date hereof, Constructors has provided Services to the LLC without a formal written agreement, however, Constructors and the
LLC are currently negotiating a formal written development services agreement governing the Services (the “Services Agreement”)( the period of time commencing on to the first day of the calendar month following the calendar month in
which the Services Agreement is executed is sometimes referred to herein as the “Post Agreement Period”), and it is anticipated that a final form of the Services Agreement will be executed no later than sixty (60) days after
the date hereof. 
 WHEREAS, the Shares will account for one million dollars ($1,000,000) of the total consideration to be paid by the
LLC to Constructors during the Post Agreement Period for the Services, with the remainder of the total consideration for the Services to be paid in cash or cash equivalents mutually agreed upon by the LLC and Constructors. 
 WHEREAS, the Shares will be subject to repurchase rights in favor of the Company as described herein, which shall lapse for Shares as the Services
are provided to the LLC according to a schedule provided in the Services Agreement. 
 WHEREAS, the Stock Purchase will otherwise be
subject to the terms and conditions contained herein. 
 WHEREAS, in addition to this Agreement and the Services Agreement, the Shares
will also be subject to a lock-up agreement in favor of the Company for a period of time mutually acceptable to the Company and the Purchaser (the “Lock-Up Agreement”) and a Registration Rights Agreement providing for piggyback, but
not demand, registration rights for the Shares (the “RRA”), final forms of which will in good faith be negotiated, finalized and executed, with terms and conditions mutually acceptable to the Company and the Purchaser, between the
Company and the Purchaser no later than sixty (60) days after the date hereof. 







 NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties,
covenants, agreements, undertakings and obligations set forth herein, the receipt and sufficiency of which are hereby acknowledged and intending to be legally bound hereby, the parties hereto agree as follows: 
 ARTICLE 1 
 SALE AND PURCHASE OF
THE SHARES 
 Section 1.1 Sale and Purchase of the Shares. Upon the terms and subject to the conditions set forth in this
Agreement, and on the basis of the representations, warranties, covenants, agreements, undertakings and obligations contained herein, Seller hereby agrees to sell to Purchaser, and Purchaser hereby agrees to accept, the Shares as partial
consideration in advance for the Services to be provided by Constructors to the LLC free and clear of any and all Liens (as defined in hereof), for the consideration specified in this. 
 Section 1.2 Purchase Price. The deemed purchase price for the Shares (the “Purchase Price”), which shall be partial
consideration for the Services to be provided by Constructors to the LLC, shall be one million dollars ($1,000,000) for a per-share purchase price of six dollars and 62/00 ($6.62) (the “Per-Share Purchase Price”). 
 Section 1.3 Certificate. Promptly after execution of this Agreement, and in any event no later than ten (10) days after the execution
hereof, the Company shall cause a duly executed certificate (the “Certificate”) evidencing the Shares in the name of the Purchaser to be created and delivered to the Purchaser. The Certificate may bear such legends reflecting the
terms hereof or terms of the Post-Issuance Agreements (defined below) as may be deemed necessary by the Company in its reasonable discretion. 
 ARTICLE 2 
 REPURCHASE RIGHTS 
 Section 2.1 Shares Issued Subject to Repurchase. The Shares are issued subject to repurchase by the Company until such repurchase rights lapse according to a schedule to be provided in the Services
Agreement. The repurchase rights for Shares will not begin to lapse until all the Post-Issuance Agreements are executed. The Company may exercise its repurchase rights with respect to any Shares at any time after issuance and prior to the time the
repurchase rights lapse for such Shares. The repurchase price for each Share shall be $0.001. In the event that the Company elects to exercise its repurchase rights with respect to any Shares, the Company shall so inform the Purchaser in writing and
the Purchaser shall immediately transfer such repurchased Shares back to the Company (and execute any stock power or other document effecting such transfer) and return the Certificate to the Company and the Purchaser shall have no further rights
with respect to the repurchased Shares. Thereafter the Purchaser will execute such additional instruments and take such actions as may be reasonably requested by the Company to carry out the intent and purpose, or otherwise reflect, such 

  

 -  - 








 
repurchase. The Company will thereafter promptly issue a new certificate evidencing the Shares which the Company did not repurchase, if any. The lapsing of
the repurchase rights shall be consideration for the agreed upon amount of the Services. Unless otherwise agreed to between the LLC and Constructors in the Services Agreement, the remainder of consideration for the Services will be paid in cash or
cash equivalent by the LLC under the terms provided in the Services Agreement. This monthly lapsing shall continue until whichever of the following occurs first: (x) the repurchase rights have lapsed with respect to all of the Shares,
(y) until the Services Agreement terminates or expires, or (z) June 30, 2009. Any lapsing of the repurchase rights shall have no effect on any other restrictions with respect to the Shares (including without limitation all
restrictions contained herein and in the Lock-Up Agreement).
