ISSUANCE AGREEMENT
  This
SECURITIES ISSUANCE AGREEMENT (this “Agreement”) is
entered into as of the 24th day of
December, 2009, by and between PETROALGAE INC., a Delaware corporation (“Seller,” or the
“Company”), and
Green Science Energy LLC (“Purchaser”).
  WITNESSETH:
  WHEREAS,
Seller desires to sell to Purchaser, and Purchaser desires to accept from
Seller, three hundred fifty-seven thousand one hundred forty-three (357,143)
(the “Shares”)
of common stock, par value $0.001 per share, of the Company (the “Common Stock”) and a
warrant to purchase three hundred fifty-seven thousand one hundred forty-three
(357,143) shares of Common Stock, in the form attached hereto as Exhibit A (the
“Warrant”, and
together with the Shares, the “Securities”) upon the
terms and subject to the conditions set forth herein.
  WHEREAS,
Purchaser is a Delaware limited liability company, and as consideration for the
Securities, is issuing the Company equity in the Purchaser equal to thirty
percent (30%) of the outstanding equity interests in the Purchaser on a fully
diluted basis, in the form to be determined and governed by an operating
agreement to be negotiated and executed pursuant to Section 1.1 below (the
“LLC
Equity”).
  NOW,
THEREFORE, in consideration of the foregoing and the respective representations,
warranties, covenants, agreements, undertakings and obligations set forth
herein, and intending to be legally bound hereby, the parties hereto agree as
follows:
  ARTICLE 1
  ISSUANCE
OF THE SECURITIES
  Section
1.1            Issuance of the
Securities.  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 sells and issues to Purchaser, and Purchaser hereby purchases from
Seller, the Securities, free and clear of any and all Liens (as defined in Section 7.11 hereof),
for the consideration specified in this Article 1.
  Section
1.2            Consideration.  As
consideration for the issuance of the Securities, Purchaser shall issue to
Seller the LLC Equity.  The parties will in good faith mutually agree
upon, finalize, and execute the operating agreement for Purchase (the “LLC
Agreement”) no later than thirty (30) days after the date
hereof.  Such LLC Agreement will, at a minimum, contain anti-dilution
protection for the LLC Equity and provide Seller with other standard and
customary rights and protections for minority-equity holders in closely held
companies (such as, solely by way of example and not by way of limitation, the
right to approve major transactions, debt facilities, new equity issuances,
equity transfers by then existing holders, events of bankruptcy, distributions,
certain amendments to the LLC Agreement, and otherwise).
  
  Section
1.3            Option to Purchase
Additional Securities.  Purchaser shall have the option (the
“Option”),
exercisable no later than June 30, 2010, to purchase up to an additional two
hundred fifty thousand (250,000) shares of Common Stock (the “Option Shares”) for
eight dollars ($8) per share, and purchase a warrant to purchase up to an
additional two hundred fifty thousand (250,000) shares of Common Stock for
fifteen dollars ($15) per share in a form substantially similar as that attached
hereto as Exhibit
“A” (the “Option Warrant”), for
a total purchase price of two million dollars ($2,000,000) (the “Option Purchase
Price”), upon and subject to the same terms and conditions as those
contained and incorporated herein; provided, however, that Seller may issue the
Option Shares and Option Warrant at such time to the Purchaser without violating
any of the securities laws, rules, or regulations of the United States or any
other country.  The Option may be exercised in whole or in part by the
Purchaser at any time prior to its expiration by delivering written notice to
Seller of Purchaser’s intent to exercise such Option.

Warrant shall bear appropriate (in the Company’s reasonable discretion)
restrictive legends reflecting the terms and conditions hereof.

hereby.  This Agreement has been duly executed and delivered by the

enforceable against the Company in accordance with its terms.
  Section
3.4            No Violations; No

conflict with, or constitute or result in a breach or violation of, or a default

body) of the Company;

agency, arbitrator, Governmental Entity or other tribunal of competent
jurisdiction (“Order”) or give any
Governmental Entity or any other Person the right to challenge the Securities
Purchase contemplated hereby; or
  (c)           require
the consent or approval of any Governmental Entity or any third party which has
not already been obtained.

Reports.  The Company has filed all reports required to be
filed by it under the Securities Act and the Securities Exchange Act of 1934, as
amended (the “Exchange
Act”), (the foregoing materials being collectively referred to herein as
the “SEC
Reports”), on a timely basis or has received a valid extension of such
time of filing and has filed any such SEC Reports prior to the expiration of any
such extension.  As of their respective dates, the SEC Reports
complied in all material respects with the requirements of the Securities Act
and the Exchange Act and the rules and regulations of the Securities and
Exchange Commission (the “Commission”)
promulgated thereunder, and none of the SEC Reports, when filed, contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. There has
been no material change in the financial condition or results of operations of
the Company and its subsidiaries taken individually and/or as whole since the
last audited financial statements of the Company included in the SEC
Reports.
  Section
3.7            No Material Adverse

September 30, 2009.
  Section
3.8            Trading With the Enemy Act;
Patriot Act.  To the knowledge of the Company, no sale of the
Company’s securities by the Company nor the Company’s use of the proceeds from
such sale has violated the Trading with the Enemy Act, as amended, or any of the
foreign assets control regulations of the United States Treasury Department (31
CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive
order relating thereto.  Without limiting the foregoing, the Company
(a) is not a person whose property or interests in property are blocked
pursuant to Section 1 of Executive Order 13224 of September 23, 2001
Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten

Stock.  The Common Stock is eligible to trade and be quoted on,
and is quoted on, the over-the-counter Bulletin Board market maintained by the
National Associate of Securities Dealers (the “OTCBB”), and the
Company has received no notice or other communication indicating that such
eligibility is subject to challenge or review by any applicable regulatory
agency, electronic market administrator, or exchange. The Company has not, and
shall not take any action that would preclude, or otherwise jeopardize, the
inclusion of the Common Stock for quotation on the OTCBB.  The Company

continue to be, in compliance with all listing requirements of the
OTCBB.

  (ii)      
    contravene, conflict with, or constitute or result in a
breach or violation of, any material Law or Order to which Purchaser, or any of
the assets owned or used by Purchaser, are subject.
  Section
4.4            Securities
Act.  Purchaser is acquiring the Securities, and will acquire
the shares of Common Stock issuable upon exercise of the Warrant (“Warrant Shares”), for
its own account and not with a view to their distribution within the meaning of
Section 2(a)(11) of the Securities Act of 1933, as amended (the “Securities Act”) in
any manner that would be in violation of the Securities Act.
  Section
4.5            Investment Representation
and Warranty.  Purchaser understands that the Securities have
not been, and the Securities and the Warrant Shares will not upon issuance be,
registered under the Securities Act, and that the Warrant and the certificates
evidencing the Shares and the Warrant Shares shall bear a legend to that
effect.
  Section
4.6            Purchaser
Status.  At the time Purchaser was offered the Securities, it
was, and at the date hereof it is, an “accredited investor” as defined in Rule

  Section
4.7            Experience of
Purchaser.  Purchaser, either alone or together with its
representatives, has such knowledge, sophistication and experience in business
and financial matters so as to be capable of evaluating the merits and risks of
the prospective investment in the Securities, and has so evaluated the merits
and risks of such investment.  Purchaser understands that it must be
able to bear the economic risk of this investment in the Securities
indefinitely, and is able to bear such risk and is able to afford a complete
loss of such investment.
  Section
4.8            Reliance on
Exemptions.  Purchaser understands that the Securities have not
been, and the Warrant Shares will not be, registered under the Securities Act or
any state securities laws and are being offered and sold in reliance upon
specific exemptions from the registration requirements of federal and state
securities laws and that the Company is relying upon the truth and accuracy of
the representations and warranties of Purchaser set forth herein in order to
determine the availability of such exemptions and the eligibility of such
Purchaser to acquire the Securities and the Warrant Shares, and that the
Securities and Warrant Shares may not be offered, sold, pledged or transferred
unless such offer, sale, pledge, or transfer is made in compliance with
applicable federal and state securities laws and the Investment Company
Act.
  Section
4.9            Appropriate
Purchaser.
  (a)           If
Purchaser is a U.S. person within the meaning of Regulation S of the Securities
Act, or a non U.S. Person who desires to purchase the Shares without relying on
Regulation S, Purchaser is a "qualified institutional buyer" (as defined in Rule
144A under the Securities Act) and is also a "qualified purchaser" (as defined
in Section 2(a)(51) under the Investment Company Act).
  6
  (b)           If
Purchaser is a non-U.S. person within the meaning of Regulation S of the
Securities Act, such Purchaser (i) is acquiring the Shares in an offshore
transaction in accordance with Rule 904 of Regulation S, (ii) is acquiring the
Shares for such Purchaser's own account, (iii) understands that the Shares may
not, absent an applicable exemption, be transferred without registration and/or
qualification under the Securities Act and applicable state securities laws and
the laws of any other applicable jurisdiction and (iv) is a non-U.S. person
within the meaning of Regulation S.
  Section
4.10          Access to
Information.  Purchaser acknowledges: (i) that it has been
afforded the opportunity to ask such questions as it has deemed necessary of,
and to receive answers from, representatives of the Company concerning the terms
and conditions of the offering of the Securities and the merits and risks of
investing in the Securities; (ii) that it has been given access to and has
carefully and completely reviewed information (other than material non-public
information) about the Company and its financial condition, results of
operations, business, properties, management and prospects sufficient to enable
it to evaluate its investment, including but not limited to the materials
provided by the Company as set forth on Exhibit B hereto, and (iii) it has been
afforded the opportunity to obtain such additional information that the Company
possesses or can acquire without unreasonable effort or expense that is
necessary to make an informed investment decision with respect to the
investment.
  Section
4.11          Restricted
Securities.  Purchaser understands that the Securities are, and
the Warrant Shares will be, characterized as “restricted securities” under the
U.S. federal securities laws inasmuch as they are being acquired from the
Company in a transaction not involving a public offering and that under such
laws and applicable regulations such securities may be resold without
registration under the Securities Act only in certain limited
circumstances.
