(ee) Independent Nature of Investors. The Company acknowledges that the obligations of each Investor under the Subscription Agreements are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under the Subscription Agreements or other transaction documents. The Company acknowledges that the decision of each Investor to purchase securities pursuant to this Offering has been made by such Investor independently of any other purchase and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have made or given by any other Investor or by any agent or employee of any other Investor, and no Investor or any of its agents or employees shall have any liability to any Investor (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein,

10

or in any transaction document, and no action taken by any Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Subscription Agreements. The Company acknowledges that each Investor shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other transaction documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each Investor has retained its own individual counsel with respect to the transactions contemplated hereby. The Company acknowledges that it has elected to provide all Investors with the same terms for the convenience of the Company and not because it was required or requested to do so by the Investors.

5. Registration Rights.

The Company grants registration rights to the Investor under the following terms and conditions:

(a) The Company shall prepare and file, at its own expense, within twenty (20) days of the Closing Date, a registration statement on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities (as defined below) on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith and with the Securities Act and the rules promulgated thereunder) under the Securities Act (the “Registration Statement”) with the Commission sufficient to permit the non-underwritten public offering and resale of all of the Shares and Warrant Shares (as subject to adjustment) (the “Registrable Securities”) through the facilities of all appropriate securities exchanges, if any, on which the Company’s Common Stock is being sold or on the over-the-counter market if the Company’s Common Stock is traded thereon; provided, however, that not less than three (3) business days prior to the filing of the Registration Statement or any related prospectus or any amendment or supplement thereto, the Company shall (i) furnish to the Investor copies of all such documents proposed to be filed, which documents will be subject to the reasonable review of the Investor, and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of the Investor and its counsel, to conduct a reasonable review of such documents.

(b) The Company will use its reasonable best efforts to cause such Registration Statement to become effective within one hundred and twenty (120) days from the Closing Date or, if earlier, within three (3) business days of Commission clearance to request acceleration of effectiveness. The number of shares designated in the Registration Statement to be registered shall include all of the Registrable Securities and shall include appropriate language regarding reliance upon Rule 416 to the extent permitted by the Commission. The Company will notify the Investor of the date of effectiveness of the Registration Statement prior to such date. The Company shall request that the effective time of the Registration Statement be 4:00 p.m. Eastern Time on the effective date and the Company shall file the final prospectus pursuant to Rule 424 of the Securities Act no later than 9:00 a.m. Eastern Time on the business day following the date the Registration Statement is declared effective by the Commission. In the event that the number of shares so registered shall prove to be insufficient to register the resale of all of the Registrable Securities, then the Company shall be obligated to file, within thirty (30) days of notice from any Investor, a further Registration Statement registering such remaining shares and shall use its reasonable best efforts to prosecute such additional Registration Statement to effectiveness within ninety (90) days of the date of such notice. The Company shall not permit any securities other than the Registrable Securities to be included in the Registration Statement.

(c) Except as otherwise provided in Section 5(k)(ii), below, the Company will maintain the Registration Statement or post-effective amendment filed under the terms of this Subscription Agreement effective under the Securities Act until the earlier of (i) the date that all of the Registrable Securities have been sold pursuant to such Registration Statement, (ii) all Registrable Securities have been otherwise transferred to Persons who may trade such shares without restriction under the Securities Act, and the Company has delivered a new certificate or other evidence of ownership for such securities not bearing a restrictive legend, or (iii) all Registrable Securities may be sold at any time, without volume or manner of sale limitations pursuant to Rule 144(k) or any similar provision then in effect under the Securities Act in the opinion of counsel to the Company (the “Effectiveness Period”). The Company shall respond as promptly as possible, but in no event later than fifteen (15) business days, to any comments received from the Commission with respect to the Registration Statement or any amendment thereto and as promptly as possible provide the Investor with true and complete copies of all correspondence from and to the Commission relating to the Registration Statement.

11

(d) If, at any time during which the Registration Statement required by Section 5(a) above is not effective, the Company shall determine to proceed with the preparation and filing of a registration statement pursuant to the Securities Act in connection with the proposed offer and sale of any of its securities by it or any of its security holders (other than a registration statement on Form S-4, S-8, or other limited purpose form), the Company will give written notice of its determination to do so to each Investor. Upon receipt of a written request from any Investor, and subject to the last sentence of this Section 5(d), within thirty (30) days after receipt of any such notice from the Company, the Company will cause all such Registrable Securities requested by the Investor to be included in such registration statement (together with a Registration Statement required by Section 5(a), a “Registration Statement”), all to the extent required to permit the sale or other disposition by such Investor, of such shares. The obligation of the Company under this Section 5(d) shall be unlimited as to the number of registration statements to which it applies, unless the Effectiveness Period has ended, provided that there shall be no duplication and any Registrable Shares which are already included in a Registration Statement (other than a Registration Statement which has been withdrawn) may not be included in any other Registration Statement. Notwithstanding the foregoing, the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 5(d). In addition, if any registration effected pursuant to this Section 5(d) is a registered public offering involving an underwriting, the Company shall so advise the Investor as part of the written notice given pursuant to this Section 5(d). In such event, the right of any Investor to include Registrable Securities in such registration pursuant to this Section 5(d) shall be conditioned upon such Investor’s execution of an underwriting agreement upon customary terms with the underwriter or underwriters selected by the Company. Furthermore, if the lead underwriter advises the Company that marketing factors require a limitation (or elimination) of shares held by selling stockholders to be underwritten, the number of Registrable Securities that may be included in such Registration Statement and underwriting, if any, shall be allocated among all Investors and other holders of registration rights requesting registration in proportion, as nearly as practicable, to the respective number of shares of held by them and for which they have registration rights on the date the Company gives the notice specified in this Section 5(d).

(e) All fees, disbursements and out-of-pocket expenses and costs incurred by the Company in connection with the preparation and filing of the Registration Statement, in making filings with NASD or NASDR (including, without limitation, pursuant to NASD Rule 2710), and in complying with applicable federal securities and Blue Sky laws (including, without limitation, all attorneys’ fees of the Company) shall be borne by the Company. The Investor shall bear the cost of underwriting and/or brokerage discounts, fees and commissions, if any, applicable to the Registrable Securities being registered, as well as the fees and expenses of their counsel. The Company shall use its reasonable best efforts to qualify any of the Registrable Securities for sale in such states as any Investor reasonably designates. However, the Company shall not be required to qualify in any state which will require an escrow or other restriction relating to the Company and/or the Investors, or which will require the Company to qualify to do business in such state or require the Company to file therein any general consent to service of process. The Company at its expense will supply each of the Investors with one unbound copy of the applicable Registration Statement and any prospectus included therein and other related documents.

(f) Certificates evidencing the Registrable Securities shall not contain any legend: (i) following any sale of such Registrable Securities pursuant to Rule 144 or an effective Registration Statement, or (ii) if such Registrable Securities are eligible for legend removal under Rule 144(k), or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). If all or any portion of a Preferred certificate or Warrant is converted or exercised at a time when such Underlying Shares may be sold under Rule 144(k) or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations thereof) then such Underlying Shares shall be issued free of all legends. The Company agrees that following the effectiveness of the Registration Statement or at such time as such legend is no longer required under this Section 5(f) pursuant to an applicable exemption from registration, it will, no later than three (3) business days following the delivery by Investor to the Company’s transfer agent of a certificate representing Registrable Securities accompanied by appropriate stock power or other required documentation, as applicable, issued with a restrictive legend (such third Business Day, the “Legend Removal Date”), deliver or cause to be delivered to such Investor a certificate representing such shares that is free from all restrictive and other legends, in each case without charge to the Investor other than customary transfer fees which may be charged by the transfer agent or broker-dealer. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section 5(f). Without limiting the Investor’s other legal remedies, the Company shall immediately upon demand reimburse the Investor for the cost and losses occasioned by any buy-in resulting from the Company’s failure to timely deliver unlegended share certificates, provided Investor provides documentation confirming such buy-in was initiated by Investor’s broker, securities custodian, or other such outside party, and not by Investor.

12

(g) In the event that (i) the Registration Statement is not filed with the Commission within twenty (20) days of the Closing Date, (ii) such Registration Statement is not declared effective by the Commission within the earlier of one hundred and twenty (120) days from the Closing Date or a request for acceleration of effectiveness is not submitted to the Commission within three (3) business days of clearance by the Commission to request effectiveness, (iii) such Registration Statement is not maintained as effective by the Company for the Effectiveness Period (except as allowed by 5(k)(ii) below), (iv) trading in the Common Stock shall be suspended or if the Common Stock is delisted from the American Stock Exchange (or other principal exchange on which the Common Stock is traded) for any reason for consecutive trading days exceeding five (5) consecutive trading days, or (v) the additional Registration Statement referred to in Section 5(b) is not filed within thirty (30) days or declared effective within ninety (90) days as set forth therein (each a “Registration Default”), then the Company will pay Investor (pro rated on a daily basis), as partial compensation for such failure and not as a penalty one and one-half percent (1.5%) of the purchase price of the Preferred purchased from the Company and held by the Investor for the first month (or portion thereof) and one percent (1%) for each month thereafter (or portion thereof) until such trading is no longer suspended (in the case of clause (iv)), until the Registration Statement has been filed (in the case of clause (i) and clause (v)), and in the event of late effectiveness (in case of clause (ii) above) or lapsed effectiveness (in the case of clause (iii) above), one and one-half percent (1.5%) of the purchase price of the Preferred purchased from the Company and held by the Investor for the first month (or portion thereof) and one percent (1%) for each month thereafter (or portion thereof) (regardless of whether one or more such Registration Defaults are then in existence, but without duplication of such partial compensatory payments) until such Registration Statement has been declared effective, provided, however, that in no event shall such payments, in the aggregate, exceed ten percent (10%) of the initial purchase price of the Preferred with respect to each Investor. Such compensatory payments shall be made to the Investors in cash, no later than the fifth business day following the month in which such Registration Default(s) occurred, provided, however, that the payment of such amounts shall not relieve the Company from its obligations to register the Registrable Securities pursuant to this Section 5. Notwithstanding anything to the contrary contained herein, in no event shall any liquidated damages be payable with respect to the Warrants or the Warrant Shares.

(h) If the Company does not remit the payment to the Investor as set forth in Section 5(g) above, the Company will pay the Investor interest at the rate of 12% per annum, or the highest rate permitted by law, if less, until such sums have been paid in full, and reasonable costs of collection, including attorneys’ fees, in addition to the liquidated damages. The registration of the Registrable Securities pursuant to this provision or payment of such compensatory amounts shall not affect or limit the Investor’s other rights or remedies as set forth in this Subscription Agreement or at law.

(i) In the event a Registration Statement is not effective at any time after one (1) year following the issuance date of the Warrants (other than an Allowed Delay, as defined in Section 5(k)(ii) below), the Warrants shall become exercisable pursuant to a cashless exercise feature, and the Company shall cause its counsel to issue such legal opinions as may be reasonably requested by the Investor in connection with any sales of the Warrant Shares in accordance with Rule 144 under the Securities Act in accordance with the procedures of Section 5(f) above. The cashless exercise feature shall be the sole remedy for any failure of such Registration Statement to be effective with respect to such Warrant Shares.

(j) At all times after one (1) year following the Closing Date, the Company will prepare and furnish to Investor and make publicly available in accordance with Rule 144(c) such information as is required for Investor to sell the Registrable Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such Person to sell such Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144. In addition, the Investor shall be entitled to unlimited piggyback registration rights under Section 5(d) above.

(k) In the case of each registration effected by the Company pursuant to any section herein, the Company will keep each Investor advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will:

13

(i) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to a disposition of all securities covered by such registration statement;

(ii) Notify the Investor at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing, and at the request of the Investors, prepare and furnish to them a reasonable number of copies of a supplement or an amendment to such prospectus as may be necessary so that, as thereafter delivered to the Investor, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing; provided that, for not more than (X) ten (10) consecutive business days (or a total of not more than thirty (30) calendar days in any twelve (12) month period) and (Y) up to an additional thirty (30) business days (consecutive or not) in any twelve (12) month period only if such material information relates to a merger or acquisition transaction, the Company may suspend the use of a prospectus included in the Registration Statement if, in the judgment of the Company, it is advisable to suspend use of such prospectus due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, or should the Company determine that a post-effective amendment to the Registration Statement is otherwise required (an “Allowed Delay”); provided, further, that the Company shall promptly (A) notify each Investor in writing of the existence of any facts or circumstances giving rise to an Allowed Delay (but in no event, without the prior written consent of such Investor, shall the Company disclose to such Investor any facts or circumstances constituting material non-public information) and (B) advise each Investor in writing to cease all sales under such registration statement until the termination of the Allowed Delay;

(iii) Use its commercially reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a registration statement, and, if such an order is issued, to obtain the withdrawal of such order at the earliest possible moment and to notify Investor (and, in the event of an underwritten offering, the managing underwriter) of the issuance of such order and the resolution thereof;

(iv) If NASD Rule 2710 requires any broker-dealer to make a filing prior to executing a sale of Registrable Securities by an Investor, make an Issuer Filing with the NASD Corporate Financing Department pursuant to NASD Rule 2710 and use its reasonable best efforts to respond within five business days to any comments received from NASD in connection therewith.

(v) Otherwise use its commercially reasonable best efforts to comply with all applicable rules and regulations of the Commission.

(l) To the extent Investor includes any Shares or Warrant Shares in a registration statement pursuant to the terms hereof, the Company will indemnify and hold harmless Investor, its directors and officers, and each Person, if any, who controls Investor within the meaning of the Securities Act, from and against, and will reimburse Investor, its directors and officers and each controlling Person with respect to, any and all loss, damage, liability, cost and expense to which Investor or such controlling Person may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, damage, liability, cost or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by Investor or any such controlling Person in writing specifically for use in the preparation thereof, including, without limitation, any information set forth in the Selling Securityholder Notice and Questionnaire attached hereto as Exhibit B and completed by Investor.

14

(m) To the extent Investor includes any Shares or Warrant Shares in a registration statement pursuant to the terms hereof, Investor will indemnify and hold harmless the Company, its directors and officers and any controlling Person from and against, and will reimburse the Company, its directors and officers and any controlling Person with respect to, any and all loss, damage, liability, cost or expense to which the Company, its directors and officers or such controlling Person may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was so made in reliance upon and in conformity with written information furnished by or on behalf of the Investor specifically for use in the preparation thereof (including, without limitation, any information set forth in the Selling Securityholder Notice and Questionnaire attached hereto as Exhibit B and completed by Investor) and provided further, that the maximum amount that may be recovered from Investor shall be limited to the amount of net proceeds received by Investor from the sale of such Shares or Warrant Shares.

(n) To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable hereunder to the extent permitted by law, provided that (i) no contribution shall be made under circumstances where the indemnifying party would not have been liable for indemnification pursuant to the provisions hereof, (ii) no seller of securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of securities who was not guilty of such fraudulent misrepresentation, and (iii) the amount of the contribution together with any other payments made in respect of such loss, damage, liability or expense, by any seller of securities shall be limited to the net amount of proceeds received by such seller from the sale of such securities.

(o) The Investor will cooperate with the Company in connection with this Subscription Agreement, including timely supplying all information and executing and returning the Selling Securityholder Notice and Questionnaire attached hereto as Exhibit B, and any other documents requested by the Company which are required to enable the Company to perform its obligations to register the Shares and the Warrant Shares.

6. Other Agreements of the Company and the Investor.

(a) Right to Pledge. The Company acknowledges and agrees that Investor may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Preferred, Shares, Warrants or Warrant Shares to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and, if required under the terms of such arrangement, such Investor may transfer pledged or secured Securities or Underlying Shares to the pledgees or secured parties. Such a pledge would not be subject to approval by the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At Investor’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of such securities may reasonably request in connection with a pledge of the Preferred, Shares, Warrants or Warrant Shares.

(b) Acknowledgment of Dilution. The Company acknowledges that the issuance of the Underlying Shares may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial. The Company further acknowledges that its obligations under this Subscription Agreement, including without limitation its obligation to issue the Shares and Warrant Shares, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Investor and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

(c) Furnishing of Information. Until the earlier of (i) five (5) years from the Closing Date or (ii) the date that all Preferred and Warrants issued in the Offering have been converted, exercised, redeemed or expired, and all Registrable Securities have been sold, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act.

15

(d) Integration. The Company shall not sell, offer for sale or solicit offers to buy any security (as defined in Section 2 of the Securities Act) the offer or sale of which would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the Offering or, if then listed or quoted on a trading market, that would be integrated with the Offering for purposes of the rules and regulations of any trading market.

(e) Exercise Procedures. The conversion procedures included in the Certificate of Designations and included in the form of Notice of Conversion for the Preferred and the form of Notice of Exercise included in the Warrant each set forth the totality of the procedures required of the Investor in order to convert its Preferred and exercise its Warrant, respectively. No additional legal opinion or other information or instructions shall be required of the Investor to convert its Preferred or exercise its Warrant. The Company shall honor conversions of the Preferred and exercises of the Warrants and shall deliver the underlying Shares or Warrant Shares, respectively, in accordance with the terms, conditions and time periods set forth in this Subscription Agreement, the Certificate of Designations of the Preferred, and the form of Warrant.

(f) Shareholders Rights Plan. No claim will be made or enforced by the Company or, to the knowledge of the Company, any other Person that any Investor is an “Acquiring Person” under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that any Investor could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving the Preferred, Shares, Warrants or Warrant Shares or under any other agreement between the Company and the Investor. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act.

(g) Eligibility to Use Form S-3. The Company currently meets, and will take all commercially reasonable actions to continue to meet, the “registrant eligibility” requirements set forth in the general instructions to Form S-3 applicable to “resale” registrations on Form S-3 during the Effectiveness Period (as defined in Section 5(c) hereof).

(h) Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder only for construction of energy and gas production facilities, and for working capital, and not for the satisfaction of any indebtedness for borrowed money (other than payment of trade payables in the ordinary course of the Company’s business and prior practices). The net proceeds to the Company shall be net of an aggregate commission of 6% of the gross proceeds payable to the Placement Agents, reimbursement to the Placement Agents of accountable expenses incurred in connection with the Offering, and other accountable fees and expenses payable by the Company in connection with the Offering. The Company will not use any proceeds from the sale of the Securities to redeem any Common Stock or securities convertible, exercisable or exchangeable into Common Stock, or to settle any outstanding litigation.

(i) Indemnification of Investor. Subject to the provisions of this Section 6(i), the Company will indemnify and hold the Investor and its directors, officers, shareholders, partners, employees and agents (each, an “Investor Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Investor Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Subscription Agreement or (b) any action instituted against Investor, or its respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Investor, with respect to any of the transactions contemplated by this Subscription Agreement (unless such action is based upon a breach of such Investor’s representation, warranties or covenants under this Subscription Agreement or any agreements or understandings such Investor may have with any such stockholder or any violations by the Investor of state or federal securities laws or any conduct by such Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Investor Party in respect of which indemnity may be sought pursuant to this Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing. Any Investor Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Investor Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Investor Party. The Company will not be liable to any Investor Party under this

16

Agreement (i) for any settlement by a Investor Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Investor Party’s breach of any of the representations, warranties, covenants or agreements made by Investor in this Subscription Agreement.

(k) Transfer and Tradability of the Shares and Warrant Shares. The Company shall provide a transfer agent and registrar for all shares of its Common Stock, including the Shares and Warrant Shares at least until such time as all the Shares and Warrant Shares have been sold. The Company shall cause all of the Shares and Warrant Shares to be listed or included for quotation on the American Stock Exchange, or any other exchange or marketplace on which the Company’s shares of Common Stock are listed or included for quotation in the future, at least until the later of (i) five (5) years from the Closing and (ii) such time as all the Shares and Warrant Shares have been sold by all of the Investors in the Offering and there are no Warrants outstanding and unexercised.

(l) Future Priced Securities. From the date hereof until the date that less than 20% of the Warrants remain outstanding and unexercised, the Company shall be prohibited from effecting or entering into an agreement to effect any financing involving a “Variable Rate Transaction” unless the Company obtains express written consent and authorization from the holders of at least seventy-five percent (75%) of the then-outstanding and unexercised Warrants. The term “Variable Rate Transaction” shall mean a transaction in which the Company issues or sells (i) any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (A) at a conversion, exercise or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock (other than customary anti-dilution protection and customary adjustments in connection with a merger or share exchange).

(m) Carbon Credit Purchase Option and Bid Right. The Investors shall have the option, pro rata based upon their respective initial purchase amounts hereunder, to purchase up to five percent (5%) of Available CERs from Microgy, Inc., at a price equal to ninety percent (90%) of the then-current market price for such Available CERs (the “Purchase Option”). “Available CERs”, as used herein, means any Certified Emission Reduction Credits (“CERs”) that are generated and owned by Microgy, Inc. (“Microgy”) during the years 2007 through 2010, excluding (i) any CERs which Microgy is required to give to (or give the economic benefit of to) any other party (including, but not limited to, pursuant to any financing arrangement) and (ii) any CERs derived from any projects under a Business Development Agreement among the Company, Microgy, and Cargill, Incorporated (including Cargill Emerging Business Accelerator Group or any of their respective affiliates or subsidiaries). Investors shall further have a first right to bid, pro rata based upon their respective initial purchase amounts hereunder, to purchase up to the remaining ninety-five percent (95%) of Available CERs not included in the Purchase Option, at the then-current market price, subject to mutually agreeable terms and conditions between the Company and each such Investor (“Bid Right”). In the event any Investor (x) shall waive, in writing, its right to participate in the Purchase Option or Bid Right, or (y) shall fail to consummate such Investor’s purchase pursuant to the Purchase Option or Bid Right, then such Investor’s Purchase Option or Bid Right shall be assigned pro rata among all other Investors participating in such Purchase Option or Bid Right, based on the respective initial purchase amounts of such participating Investors hereunder. Notwithstanding anything to the contrary contained herein, in no event shall the Investors have the right to acquire, in the aggregate, more than 15,000,000 metric tons of Available CERs hereunder. Microgy, by executing the signature page hereto, acknowledges its agreement to offer the Purchase Option and Bid Right to the Investors pursuant to the terms of this paragraph (m).

(n) Right of First Refusal. For a period of one (1) year following the Closing Date, the Company agrees to promptly notify each Investor in writing (a “Rights Notice”) of the terms and conditions of any proposed private placement offering of Common Stock or securities convertible or exercisable into shares of Common Stock (“Subsequent Financing”), not including offerings pursuant to (i) equity incentive plans established for the benefit of the Company’s employees, consultants, officers or directors, (ii) warrants, or shares issuable upon exercise thereof, issued to Cargill, Incorporated pursuant to the terms of any Business Development Agreement or similar agreement entered into among the Company, Microgy, Inc. and Cargill, Incorporated, (iii) other strategic partnerships, (iv) mergers or acquisitions, or (v) public offerings; provided, however, prior to delivering to each Investor a Rights Notice, the Company shall first deliver to each Investor a written notice of its intention to effect a Subsequent

17

Financing (“Pre-Notice”) within three (3) trading days of receiving an applicable offer, which Pre-Notice shall ask such Investor if it wants to review the details of such financing. Upon the request of an Investor, and only upon a request by such Investor within three (3) trading days of receipt of a Pre-Notice, the Company shall promptly, but no later than two (2) trading days after such request, deliver a Rights Notice to such Investor. The Rights Notice shall grant Investors the right to purchase their pro rata portion, based on their respective initial purchase amounts hereunder, of all or part of the securities being offered in such Subsequent Financing, on the same, absolute terms and conditions as contemplated by such Subsequent Financing, and shall be delivered at least ten (10) business days prior to the closing of any such Subsequent Financing. Each Investor will have ten (10) business days from the date of the Rights Notice in which to advise the Company in writing whether it intends to participate in such Subsequent Financing, and in what amounts, which amount shall not exceed Investor’s purchase amount hereunder except as allowed by the following sentence (unless otherwise agreed between the Company and Investor without infringing on the rights of any other Investor hereunder). If any Investor elects not to participate in such Subsequent Financing, the purchase right granted to such Investor pursuant to its Rights Notice shall be assigned pro rata among all other Investors participating in the Subsequent Financing, based on the respective initial purchase amounts of such participating Investors hereunder.

(o) Equal Treatment of Investors. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of such Person’s Subscription Agreement unless the same consideration is also offered to all Investors in the Offering. For clarification purposes, this provision constitutes a separate right granted to each Investor by the Company and shall not in any way be construed as the Investors in the Offering acting in concert or as a group with respect to the purchase, disposition or voting of the Preferred, Shares, Warrants, Warrant Shares or otherwise.

(p) Disclosure of Transaction. The Company shall issue a press release describing the material terms of the transactions contemplated hereby (the “Press Release”) as soon as practicable after the date of execution of this Subscription Agreement. The Company shall also file with the Commission a Current Report on Form 8-K (the “Form 8-K”) describing the material terms of the transactions contemplated hereby (and attaching as exhibits thereto this Agreement, the Certificate of Designations of the Preferred, the form of Warrant and the Press Release) as soon as practicable following the date of this Subscription Agreement but in no event more than four (4) business days following the date of this Subscription Agreement, which Press Release and Form 8-K shall be subject to prior review and comment by the Investors.

(q) Disclosure of Material Information. The Company covenants and agrees that neither it nor any other person acting on its behalf will provide any Investor or its agents or counsel with any information that the Company believes constitutes material non-public information (other than with respect to the transactions contemplated by this Subscription Agreement), unless prior thereto such Investor shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that the Investors shall be relying on the foregoing representations in effecting transactions in securities of the Company.

(r) Reservation of Shares. The Company shall at all times while the Securities are outstanding reserve from its duly authorized capital stock a number of shares of Common Stock required for issuance of the Shares and the Warrant Shares.
