Authorization.

If the Subscriber is a natural person or if beneficial ownership of the Subscriber is held by an individual through a revocable grantor trust or an estate planning vehicle, the Subscriber or the Subscriber’s beneficial owner is at least twenty-one (21) years old and it is within the Subscriber’s right, power and capacity to execute this Subscription Agreement, the Partnership Agreement, the Power of Attorney, and the Investor Qualification Statement and the Anti-Money Laundering & Know Your Customer Supplement, to invest in the Partnership and to fund its Capital Commitment as contemplated by, and in accordance with, this Subscription Agreement and the Partnership Agreement.  If the Subscriber lives in a community property state in the United States, either (A) the source of the Subscriber’s Capital Commitment will be the Subscriber’s separate property and the Subscriber will hold the Interests as separate property or (B) the Subscriber alone has the authority to bind the community with respect to this Subscription Agreement, the Partnership Agreement, the Power of Attorney, the Investor Qualification Statement and the Anti-Money Laundering & Know Your Customer Supplement and all agreements contemplated hereby and thereby.

If the Subscriber is a corporation, limited liability company, partnership, trust, governmental plan or other entity, the Subscriber is duly organized, formed or incorporated, as the case may be, and the Subscriber is authorized, empowered and qualified to execute this Subscription Agreement, the Partnership Agreement, the Power of Attorney and the Investor Qualification Statement and the Anti-Money Laundering & Know Your Customer Supplement, to invest in the Partnership and to fund its Capital Commitment as contemplated by, and in accordance with, this Subscription Agreement and the Partnership Agreement.  The individual signing this Subscription Agreement, the Partnership Agreement, the Power of Attorney and the Investor Qualification Statement and the Anti-Money Laundering & Know Your Customer Supplement and all agreements contemplated hereby and thereby on the Subscriber’s behalf has been duly authorized to do so.

Execution; Binding Obligation.  The Subscriber agrees to execute the Partnership Agreement simultaneously with the execution of this Subscription Agreement.  The Partnership Agreement shall become binding upon the Subscriber on the later of (i) the date of the Partnership Agreement and (ii) the date, if any, that the General Partner accepts this subscription in whole or in part.  Each of this Subscription Agreement, the Partnership Agreement (including Section 11.2 thereof), the Investor Qualification Statement, the Anti-Money Laundering & Know Your Customer Supplement and the Power of Attorney is a valid and binding agreement or instrument, as applicable, enforceable against the Subscriber in accordance with its terms.  The Subscriber understands that, upon acceptance by the General Partner and except as explicitly provided for by applicable law in certain non-United States jurisdictions, the Subscriber is not entitled to cancel, terminate or revoke this Subscription Agreement or any of the powers conferred herein.  The Subscriber represents and warrants that the Power of Attorney granted by the Subscriber in connection with this Subscription Agreement has been executed by it in compliance with the laws of the state or jurisdiction in which this Subscription Agreement was executed and to which the Subscriber is subject.  The Subscriber hereby covenants and agrees on behalf of itself and its successors and assigns, without further consideration, to prepare, execute, acknowledge, file, record, publish and deliver such other instruments, documents and statements and to take such other actions as the General Partner may determine to be necessary or appropriate to effectuate and carry out the purposes of this Subscription Agreement, the Investor Qualification Statement and the Partnership Agreement.

No Conflict.  The execution and delivery of and/or adherence to, as applicable, this Subscription Agreement, the Investor Qualification Statement, the Power of Attorney, the Anti-Money Laundering & Know Your Customer Supplement and the Partnership Agreement by or on behalf of the Subscriber, the consummation of the transactions contemplated hereby and thereby, and the performance of the Subscriber’s obligations under this Subscription Agreement, the Power of Attorney and the Partnership Agreement will not conflict with, or result in any violation of or default under, any provision of any governing instrument applicable to the Subscriber, or any agreement or other instrument to which the Subscriber is a party or by which the Subscriber or any of its properties are bound, or any United States or non-United States permit, franchise, judgment, decree, statute, order, rule or regulation applicable to the Subscriber or the Subscriber’s business or properties.

Offering Materials and Other Information.  The Subscriber has received and read a copy of the confidential Private Placement Memorandum of Energy Capital Partners III, LP (as amended, restated or supplemented on or prior to the acceptance date for this subscription, the “Private Placement Memorandum”) and the confidential Project Royal Co-Investment Opportunity presentation regarding the Volt co-investment opportunity (as amended, restated or supplemented on or prior to the acceptance date for this subscription, the “Co-Investment Memorandum”), this Subscription Agreement and the Partnership Agreement provided to the Subscriber before the General Partner’s initial acceptance of any of the Subscriber’s requested capital commitment amount (collectively, the “Offering Materials”), as well as Form ADV Part 2A for Energy Capital Partners Management, LP, and the Subscriber has relied on nothing other than the Offering Materials, its own diligence and its own professional advisors in deciding whether to make an investment in the Partnership.  The Subscriber understands that the Offering Materials contain materials that speak only as of their respective dates and that the information therein has not been updated through the date of this Subscription Agreement.  In addition, the Subscriber acknowledges that the Subscriber has been given the opportunity to (i) ask questions and receive satisfactory answers concerning the terms and conditions of the offering, (ii) perform its own independent investigations and (iii) obtain additional information in order to evaluate the merits and risks of an investment in the Partnership and to verify the accuracy of the information contained in the Offering Materials.  No statement, printed material or other information that is contrary to the information contained in the Offering Materials has been given or made by or on behalf of the General Partner, its affiliates and/or the Partnership to the Subscriber.  The Subscriber has consulted to the extent deemed appropriate by the Subscriber with the Subscriber’s own advisers as to the financial, tax, legal, accounting, regulatory and related matters concerning an investment in the Interests and on that basis understands the financial, tax, legal, accounting, regulatory and related consequences of an investment in the Interests, and believes that an investment in the Interests is suitable and appropriate for the Subscriber. The Offering Materials do not comprise, and may not be construed as comprising, any solicitation of any proxy, any procurement, withholding, or revocation of any proxy, or any other action in respect of any proxy.

No Registration of Interests.  The Subscriber understands that the Interests have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the “Securities Act”), or any state or non-United States securities laws, and are being offered and sold in reliance upon United States federal, state and applicable non-United States exemptions from registration requirements for transactions not involving a public offering.  The Subscriber recognizes that reliance upon such exemptions is based in part upon the representations of the Subscriber contained in this Subscription Agreement, the Investor Qualification Statement and the Tax Forms.  The Subscriber represents and warrants that the Interests will be acquired by the Subscriber solely for the account of the Subscriber, for investment purposes only and not with a view to the distribution thereof.  The Subscriber represents and warrants that the Subscriber (i) is a sophisticated investor with the knowledge and experience in business and financial matters to enable the Subscriber to evaluate the merits and risks of an investment in the Partnership, (ii) is able to bear the economic risk and lack of liquidity of an investment in the Partnership and (iii) is able to bear the risk of loss of its entire investment in the Partnership.  The Subscriber’s Capital Commitment, together with the Subscriber’s other investments that are not readily marketable, is not disproportionate to the Subscriber’s net worth.  If the Subscriber is a Non-US Partner, the Subscriber meets any additional or different suitability standards imposed by the securities laws (and any similar laws) of the country, state or other jurisdiction of the Subscriber’s principal place of business or domicile and the Subscriber is eligible, under all laws, regulations and governmental orders applicable to the Subscriber, to (1) receive and accept an offer to sell or a solicitation of the Subscriber’s offer to purchase the Interests in the manner made to the Subscriber, (2) accept delivery (including, without limitation, electronic delivery) of, and review, the Offering Materials and (3) subscribe for and purchase the Interests as contemplated hereby.

Regulation D under the Securities Act.  The Subscriber is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated under the Securities Act.

Rule 506(d) of Regulation D.  As of the date hereof, the Subscriber has not been subject to any event specified in Rule 506(d)(1) of the Securities Act or any proceeding or event that could result in any such disqualifying event (“Disqualifying Event”) that would either require disclosure under the provisions of Rule 506(e) of the Securities Act or result in disqualification under Rule 506(d)(1) of the Partnership’s use of the Rule 506 exemption.  The Subscriber will immediately notify the General Partner in writing if the Subscriber becomes subject to a Disqualifying Event at any date after the date hereof.  In the event that the Subscriber becomes subject to a Disqualifying Event at any date after the date hereof, the Subscriber agrees and covenants to use its best efforts to coordinate with the General Partner to provide documentation as reasonably requested by the General Partner related to any such Disqualifying Event.  Furthermore, if a Disqualifying Event occurs at any time after the date hereof, then (i) the Subscriber’s voting rights in respect of the Partnership’s outstanding voting equity securities (calculated on the basis of voting power) may, in the sole discretion of the General Partner, be automatically reduced, for such period of time as the General Partner determines is necessary or advisable (which reduction may be retroactive and/or prospective), to the lesser of 19.9% and the Subscriber’s then-current Percentage Interest (as defined in the Partnership Agreement), and the General Partner is hereby authorized on behalf of the Subscriber to take such action as the General Partner deems necessary or appropriate to give effect to the same, and/or (ii) if the General Partner determines that for any reason such reduction is not sufficient to avoid any adverse impacts under Rule 506(d) or 506(e) of Regulation D under the Securities Act, the General Partner may deem the Subscriber’s continuing participation in the Partnership to have a Material Adverse Effect for purposes of Section 9.10.1 of the Partnership Agreement, in which case the General Partner may invoke any of the remedies described therein without providing the Subscriber the opportunity to assign all or any portion of its Interest.  The Subscriber also acknowledges that the General Partner may periodically request assurance that the Subscriber has not become subject to a Disqualifying Event at any date after the date hereof, and the Subscriber further acknowledges and agrees that the General Partner shall understand and deem the failure by the Subscriber to respond in writing to such requests to be an affirmation and restatement of the representations, warranties and covenants in this Section (g).

Investment Company Act Matters.  The Subscriber understands that (i) the Partnership does not intend to register as an investment company under the United States Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder (the “Investment Company Act”), and (ii) accordingly, the provisions of the Investment Company Act (which, among other matters, require investment companies to have a majority of disinterested directors) will not be applicable to the Partnership.  Except as expressly indicated on the Investor Qualification Statement, the Subscriber was not formed or reformed (as interpreted under the Investment Company Act) for the specific purpose of making an investment in the Partnership, and, under the ownership attribution rules promulgated under Section 3(c)(1) of the Investment Company Act, no more than one person will be deemed a beneficial owner of the Subscriber’s Interest.  Unless the Subscriber has indicated otherwise in the Investor Qualification Statement, then the Subscriber is a “qualified purchaser” as that term is defined in Section 2(a)(51) of the Investment Company Act and the rules and regulations promulgated thereunder.

Acknowledgement of Risks; Restrictions on Transfer.  The Subscriber recognizes that (i) an investment in the Partnership involves certain risks, (ii) the Interests will be subject to certain restrictions on transferability as described in the Partnership Agreement and (iii) as a result of the foregoing, the marketability of the Interests will be severely limited.  The Subscriber agrees that it will not transfer, sell, assign, pledge, encumber, mortgage, divide, hypothecate or otherwise dispose of all or any portion of the Interests in any manner that would (A) violate the Partnership Agreement, the Securities Act or any United States federal or state or non-United States securities laws, (B) subject the Partnership, the General Partner or any of their respective affiliates to regulation under the Investment Company Act or (C) make materially more burdensome for such Person any regulatory requirement under the Investment Company Act, the United States Investment Advisers Act of 1940, as amended, and the rules and regulations promulgated thereunder (the “Investment Advisers Act”) (in the case of the Investment Advisers Act, to which such persons or entities are not already otherwise subject), the rules and regulations of the United States Securities and Exchange Commission or the laws and regulations of any United States federal, state or municipal authority or any non-United States governmental authority having jurisdiction thereover.  Except as otherwise disclosed in writing to the General Partner, neither the Subscriber nor any of its affiliates is a party to any financial instrument or contract (other than this Subscription Agreement and the Partnership Agreement) the value of which is determined in whole or in part by reference to the Partnership (including the amount of distributions by the Partnership, the value of Partnership assets or the results of Partnership operations).

Additional Investment Risks.  The Subscriber is aware that (i) the Partnership has no financial or operating history, (ii) investment returns set forth in the Private Placement Memorandum, the Co-Investment Memorandum or in any supplemental letters or materials thereto are not necessarily comparable to or indicative of the returns, if any, that may be achieved on investments made by, or in, the Partnership, (iii) the General Partner or a person or entity selected by the General Partner (which may be a manager, member, shareholder, partner or affiliate thereof) may be entitled to receive substantial compensation in connection with the management of the Partnership, and (iv) no United States federal, state or local or non-United States agency, governmental authority or other person has passed upon the Interests or made any finding or determination as to the fairness of this investment.  In addition, the Subscriber acknowledges and agrees that (I) there can be no assurance any projected returns contained in the Offering Materials will be achieved, (II) such projected returns are based on certain assumptions made by the General Partner which may not prove accurate and therefore actual investment returns may differ materially, (III) the Subscriber does not regard the inclusion of such projected returns as an indication that the General Partner considers such projections to be a reliable prediction of future events and the projections should not be relied upon by investors and (IV) such projected returns are presented solely to demonstrate how the General Partner evaluates the related investment opportunity and are not intended to be a prediction of future results.

No Public Solicitation of Subscriber.  The Subscriber confirms that it is not subscribing for any Interest as a result of any form of general solicitation or general advertising, including (i) any advertisement, article, notice or other communications published in any newspaper, magazine or similar media (including any internet site that is not password protected) or broadcast over television or radio or (ii) any seminar or meeting whose attendees were invited by any general solicitation or general advertising.

Additional Representations of Non-US Limited Partner.  The Subscriber understands that if the jurisdiction of its principal place of business, residence or domicile is outside the United States, it is the Subscriber’s responsibility to satisfy itself as to full observance of the law of any relevant territory outside the United States in connection with the offer and sale of the Interests, including obtaining any required governmental or other consent and observing any other applicable formalities.  The Subscriber represents that it meets any additional or different suitability standards imposed by the securities and other laws of the jurisdiction of its principal place of business, residence or domicile applicable to or required in connection with an investment in the Partnership and that it has received any required governmental or other consents or approvals in connection with its investment in an Interest.  The Subscriber understands that if it is a person or entity described in this paragraph, it may be required to make additional representations to the General Partner and the Partnership in connection with the applicable laws of the applicable jurisdiction.

Principal Residence.  If the Subscriber is a natural person, the Subscriber’s domicile and principal residence are maintained at the legal address provided to the General Partner in the Subscription Information Sheet (and any accompanying attachments) submitted by the Subscriber herewith, and the Subscriber has no present intention of becoming a resident of any other state or jurisdiction.  If the Subscriber is a corporation, trust, partnership, joint venture or other organization, the Subscriber has its domicile, principal place of business, or principal office at the legal address provided to the General Partner in the Subscription Information Sheet (and any accompanying attachments) submitted by the Subscriber herewith, and the Subscriber has no present intention of relocating such domicile, principal place of business, or principal office to any other state or jurisdiction.

Additional Private Placement Representations.  The Subscriber confirms that it (i) has a pre-existing personal or business relationship with the General Partner and/or any of its principals, agents or affiliates, and (ii) has the capacity to protect its own interests in connection with the purchase of its Interest and its admission as a Limited Partner, by reason of its business or financial experience or the business or financial experience of its professional advisors that are unaffiliated with (and not compensated by) the Partnership, the General Partner or any affiliate or selling agent of the Partnership or the General Partner, directly or indirectly.

Investment Advisers Act Matters.  The Subscriber, as well as any direct or indirect beneficial owner of the Subscriber that would be identified as a “client” under Rule 205-3 under the Investment Advisers Act, is a “qualified client” within the meaning of the Investment Advisers Act.  The Subscriber agrees that the General Partner and the Partnership may provide in any electronic medium (including via email or website access) any disclosure or document that is required by applicable law to be provided to the Subscriber.  In addition, the Subscriber hereby agrees that the Persons designated in the Partnership Agreement to provide Investment Advisers Act approvals on behalf of the Subscriber, including, without limitation, any approvals required under Section 206(3) of the Investment Advisers Act and any consent to a transaction that would result in any “assignment” (within the meaning of the Investment Advisers Act) with respect to the General Partner, are appointed and authorized to do so on behalf of the Subscriber.

Tax Status of Flow-Through Subscriber.  If the Subscriber is a partnership, a limited liability company treated as a partnership (or as a disregarded entity) for United States federal income tax purposes, a grantor trust (within the meaning of §§671-679 of the United States Internal Revenue Code of 1986, as amended (the “Code”)) or an S corporation (within the meaning of Code §1361) (each a “flow-through entity”), the Subscriber represents and warrants that either:

no person or entity will own, directly or indirectly through one or more flow-through entities, an interest in the Subscriber such that more than 70% of the value of such person’s or entity’s interest in the Subscriber is attributable to the Subscriber’s investment in the Partnership; or

if one or more persons or entities will own, directly or indirectly through one or more flow-through entities, an interest in the Subscriber such that more than 70% of the value of such person’s or entity’s interest in the Subscriber is attributable to the Subscriber’s investment in the Partnership, neither the Subscriber nor any such person or entity has or had any intent or purpose to cause such person (or persons) or entity (or entities) to invest in the Partnership indirectly through the Subscriber in order to enable the Partnership to qualify for the 100-partner safe harbor under United States Department of Treasury Reg. §1.7704-1(h).

Tax Information.

If the Subscriber is a “US Partner” (as defined below), the Subscriber certifies under penalties of perjury that (A)(i) its identity, taxpayer identification or social security number and address provided in the Subscriber Information (as defined below) is correct and (ii) it will complete and return with this Subscription Agreement IRS Form W-9, and (B)(i) it is not a non-resident alien individual, foreign corporation, foreign partnership, foreign trust or foreign estate (as defined in the Code) and (ii) it will notify the Partnership promptly, and in any event within 30 days, of any change in its United States tax or withholding status.

If the Subscriber is a “Non-US Limited Partner” (as defined below), the Subscriber certifies under penalties of perjury that (A)(i) its identity and address provided in the Subscriber Information are correct and (ii) it will complete and return with this Subscription Agreement (1) the applicable IRS Form(s) W-8 (W-8BEN, ▇-▇▇▇▇-▇, ▇-▇▇▇▇, ▇-▇▇▇▇  or W-8EXP) requested in the directions accompanying this Subscription Agreement and (2) if the Subscriber has claimed a reduced rate of withholding tax pursuant to an income tax treaty to which the United States is a party, a Certificate under Code Section 894(c) (“Section 894(c) Certificate”) requested in the directions accompanying this Subscription Agreement, (iii) the Subscriber will notify the Partnership within 30 days of any change in circumstances that makes any IRS Form(s) W-8 or any completed Section 894(c) Certificate submitted incorrect or inappropriate for the Subscriber, and (iv) the Subscriber will, within 30 days of a request from the General Partner, provide the General Partner with any other IRS Form(s) that are reasonably requested by the General Partner, including any document requested by the General Partner in connection with the Partnership or any alternative investment vehicle establishing an exemption or reduction in withholding under Sections 1471 through 1474 of the Code and (B)(i) it is a non-resident alien individual, foreign corporation, foreign partnership, foreign trust or foreign estate (as defined in the Code) and (ii) it will notify the Partnership promptly, and in any event within 30 days, of a change in such status.

For purposes of this Subscription Agreement, the Subscriber is a “US Partner” if it qualifies as a “U.S. Person” for purposes of Section 7701(a)(30) of the Code, and the Subscriber is a “Non-US Limited Partner” if it does not so qualify.

Under penalties of perjury, the Subscriber certifies that it has not been notified that it is subject to backup withholding as a result of a failure to report all interest or dividends, unless the Internal Revenue Service has since notified it that it is no longer subject to backup withholding.

The Subscriber will cooperate with the General Partner with respect to all tax matters and agrees to duly execute and provide to the General Partner in a timely manner any tax documentation that may be reasonably requested in connection with the Partnership.

Benefit Plan Investor Status of Subscriber.  The Subscriber represents and warrants that the Subscriber is not (i) an “employee benefit plan” that is subject to Title I of the United States Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) an individual retirement account or annuity or other “plan” that is subject to Section 4975 of the Code, or (iii) a fund of funds, an insurance company separate account or an insurance company general account or another entity or account (such as a group trust), in each case whose underlying assets are deemed under the U.S. Department of Labor regulation codified at 29 C.F.R. § 2510.3-101, as modified by Section 3(42) of ERISA (the “Plan Asset Regulation”), to include “plan assets” of any “employee benefit plan” subject to ERISA or “plan” subject to Section 4975 of the Code (each of (i) through (iii), a “Benefit Plan Investor”).  The Subscriber also represents, warrants and covenants that it shall not become a Benefit Plan Investor for so long as it holds Interests.

The Plan’s decision to invest in the Partnership was made by duly authorized fiduciaries in accordance with the Plan’s governing documents, which fiduciaries are independent of the Partnership, the General Partner, the Manager, and their affiliates.  No advice or recommendations of the Partnership, the General Partner, the Manager, or any of their affiliates was relied upon by such fiduciaries in deciding to invest in the Partnership.  Such fiduciaries have considered any fiduciary duties or other obligations arising under ERISA, Section 4975 of the Code and any other non-U.S., federal, state or local law substantially similar to ERISA or Section 4975 of the Code (“Similar Law”), including any regulations, rules and procedures issued thereunder and related judicial interpretations, in determining to  invest in the Partnership, and such fiduciaries have determined that an investment in the Partnership is consistent with such fiduciary duties and other obligations.

No discretionary authority or control was exercised by the Partnership, the General Partner, the Manager, or any of their respective affiliates in connection with the Plan’s investment in the Partnership.  No individualized investment advice was provided to the Plan by the Partnership, the General Partner, the Manager, or their affiliates based upon the Plan’s investment policies or strategies, overall portfolio composition or diversification with respect to its investment in the Partnership.

The Subscriber acknowledges and agrees that the Partnership does not intend to hold plan assets of the Plan and that none of the Partnership, the General Partner, the Manager, or any of their respective affiliates will act as a fiduciary to the Plan under ERISA, the Code or any Similar Law with respect to the Subscriber’s purchase or retention of an Interest in the Partnership or the management or operation of the Partnership.

Assuming the assets of the Partnership are not “plan assets” within the meaning of Section 3(42) of ERISA, the Subscriber’s acquisition and holding of Interests will not constitute or result in a non-exempt “prohibited transaction” under ERISA or Section 4975 of the Code or a violation of any Similar Law.

The information provided in Part IV of the Investor Qualification Statement, if the Subscriber is a natural person or alter-ego thereof, or Part V of the Investor Qualification Statement, if the Subscriber is an entity, is true and accurate as of the date hereof; such information will remain true and accurate for so long as the Subscriber holds Interests in the Partnership; and the Subscriber agrees to notify the Partnership immediately if it has any reason to believe that it is or may be in breach of the foregoing representation and covenant.

Anti-Money Laundering and Anti-Boycott Matters.  The Subscriber acknowledges that the Partnership seeks to comply with all applicable anti-money laundering and anti-boycott laws and regulations. In furtherance of these efforts, the Subscriber represents, warrants and agrees that: (i) no part of the funds used by the Subscriber to acquire the Interests or to satisfy its capital commitment or contribution obligations with respect thereto has been, or shall be, directly or indirectly derived from, or related to, any activity that may contravene United States federal or state or non-United States laws or regulations, including anti-money laundering laws and regulations, (ii) no capital commitment, contribution or payment to the Partnership by the Subscriber and no distribution to the Subscriber shall cause the Partnership or the General Partner to be in violation of any applicable anti-money laundering laws or regulations including, without limitation, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT ACT) Act of 2001 and the United States Department of the Treasury Office of Foreign Assets Control (“OFAC”) regulations and (iii) all capital contributions or payments to the Partnership by the Subscriber will be made through an account located in a jurisdiction that does not appear on the list of boycotting countries published by the United States Department of Treasury pursuant to Section 999(a)(3) of the Code, in effect at the time of such contribution or payment.  The Subscriber acknowledges and agrees that, notwithstanding anything to the contrary contained in the Partnership Agreement, any side letter or any other agreement, to the extent required by any anti-money laundering law or regulation or by OFAC, the Partnership and the General Partner may prohibit additional capital contributions, restrict distributions or take any other reasonably necessary or advisable action with respect to the Interests, and the Subscriber shall have no claim, and shall not pursue any claim, against the Partnership, the General Partner or any other Person in connection therewith.

Privacy Notice.  If a natural person (or an entity that is an “alter ego” of a natural person (e.g., a revocable grantor trust or an estate planning vehicle)), the Subscriber has received and read a copy of the initial privacy notice with respect to the General Partner’s collection and maintenance of non-public personal information regarding the Subscriber, and the Subscriber hereby requests and agrees, to the extent permitted by applicable law, that the General Partner shall refrain from sending to the Subscriber (i) an annual privacy notice, as contemplated by 16 CFR Part 313, §313.5 (the Federal Trade Commission’s Final Rules regarding the Privacy of Consumer Financial Information (the “FTC’s Final Privacy Rules”)), provided that the General Partner keeps an annual privacy notice with the books and records of the business and such annual privacy notice is available to the Subscriber upon its request, and (ii) any other information regarding the customer relationship, as contemplated by 16 CFR Part 313, §313.9(c)(2) of the FTC’s Final Privacy Rules.  The Subscriber understands that, at any time subsequent to the date hereof, it may elect to receive any information contemplated by clauses (i) and (ii) above, but only to the extent that the General Partner is required by applicable law to deliver such information, by providing reasonable prior written notice to the General Partner to such effect.

Confidentiality.  The Subscriber acknowledges and agrees that (i) it has received and will in the future receive information described in Section 11.11 of the Partnership Agreement (“Confidential Information”) regarding the Partnership, the ECP III Funds, the Other ECP Funds, the General Partner, the Manager, their respective portfolio companies and investments, the equity owners of the General Partner and each of their respective affiliates (collectively, the “Partnership Entities”) as well as the other participants in the Partnership Entities (collectively, the “Participants”), (ii) such Confidential Information contains trade secrets and is proprietary, (iii) disclosure of such Confidential Information to third parties is not in the best interest of any of the Partnership Entities or the Participants therein and (iv) disclosure of such Confidential Information would cause substantial harm and damages to the Partnership Entities and the Participants therein.  The Subscriber hereby represents and warrants that, except as previously disclosed to the General Partner in writing, (A) it is not subject to any law, statute, governmental rule or regulation or judicial or governmental order, judgment or decree requiring it to disclose any information or materials (whether or not Confidential Information) relating to any of the Partnership Entities or the Participants therein to any Person(s) and (B) it is not required by any law, statute, governmental rule or regulation or judicial or governmental order, judgment or decree or any agreement or contract to obtain any consent or approval prior to agreeing to be bound by the confidentiality covenant set forth in the Partnership Agreement.  The Subscriber hereby represents and warrants that except as previously disclosed in writing to the General Partner, it has taken all actions and obtained all consents necessary to enable it to comply with the provisions of Section 11.11 of the Partnership Agreement.  The Subscriber hereby agrees that it will not use any Confidential Information it receives for any purpose other than monitoring and evaluating its investment in the Partnership.  Any information provided to a Person at the direction or request of the Subscriber shall be treated for purposes hereof and for purposes of the Partnership Agreement as instead having been provided to such Person by the Subscriber, and such deemed disclosure by the Subscriber shall be subject to all of the limitations and other provisions in the Partnership Agreement relating to Confidential Information.

Ownership of Subscriber by Individuals.  If the Subscriber is not a natural person (or an entity that is an “alter ego” of a natural person (e.g., a revocable grantor trust or an estate planning vehicle)), no person who is treated as an individual under Section 542(a)(2) of the Code Beneficially Owns (as defined below) more than 9.8% by value of the Subscriber.  For purposes of this representation, “Beneficially Owns” means ownership by a person who would be treated as an owner of the Subscriber either directly, indirectly, or constructively through the application of Section 544 of the Code.

Regulatory Representations.  The Subscriber hereby represents, warrants, agrees and acknowledges as of the date hereof that unless otherwise indicated in writing to the General Partner, the Subscriber is not subject to, nor is it subject to but exempt from, regulation as a “holding company,” or a “subsidiary company” or an “affiliate” of a “holding company,” under the Public Utility Holding Company Act of 2005.

Ability to Fund.

The Subscriber will maintain sufficient liquid assets or written and enforceable commitments from its investors (if any) to enable it to make any capital contributions to the Partnership or payments as and when required pursuant to the Partnership Agreement.

There is no legal action, suit, arbitration or other legal, administrative or other governmental investigation, inquiry or proceeding (whether federal, state, local, foreign or other) pending or threatened against (i) the Subscriber, and (ii) if the Subscriber is an entity, any of its directors, general partners, managing members or similar officers or any of its properties, assets or business, in each case that may reasonably be expected to have a material adverse effect on its ability to fund its Capital Commitment.  To the best of the Subscriber’s knowledge, there is no reasonable basis for any such action, suit, arbitration, investigation inquiry or proceeding that may reasonably be expected to have a material adverse effect on the Subscriber’s ability to fund its Capital Commitment or payments required pursuant to the Partnership Agreement.

The Subscriber has not pledged or granted (except to the Partnership) a security interest upon its Interest, and will not suffer any such pledge, assignment in security, or grant of its Interest unless: (i) in compliance with the Partnership Agreement, and (ii) it has provided prior written notice thereof to the General Partner.

Neither the Subscriber nor any of its affiliates is a party to any financial instrument or contract (other than this Subscription Agreement and the Partnership Agreement) the value of which is determined in whole or in part by reference to the Partnership (including the amount of distributions by the Partnership, the value of Partnership assets or the results of Partnership operations).

Related Parties.  Except as described in writing by the Subscriber to the General Partner and received by the General Partner at least five business days prior to the date hereof: (i) the Subscriber does not control, is not controlled by, and is not under common control with, any other Limited Partner (or subscriber for Interests to the Partnership), and (ii) no other Person will have a beneficial interest in the Interests to be acquired by the Subscriber hereunder (other than in such person’s or entity’s capacity as a shareholder, partner, member, policy owner or other beneficial owner of equity interests in the Subscriber).

Notwithstanding anything to the contrary set forth herein, but subject to the terms and conditions set forth in section 11.11 of the Merger Agreement, Volt shall be an express third-party beneficiary hereof and of the rights granted to the General Partner to issue Capital Call Notices to the Subscriber pursuant to Section 3.2.2(a) of the Partnership Agreement, and shall be entitled to specifically enforce the obligations of Subscriber directly against Subscriber to the full extent hereof and thereof, and, in connection therewith, Volt shall have the right to obtain an injunction, or other appropriate form of specific performance or equitable relief, to cause the Partnership to cause, or to directly cause, Subscriber to fund, directly or indirectly, (i) its Capital Commitment (as defined in the Partnership Agreement) and (ii) the payment of any and all fees and expenses required to be paid by the Subscriber in connection with the Merger pursuant to and in accordance with the Partnership Agreement and the Merger Agreement. Subscriber hereby waives (A) any defense to specific performance that a remedy at law would be adequate or that, absent specific performance, no irreparable harm would be suffered and (B) any requirement under applicable law to post a bond or other security as a prerequisite to obtaining equitable relief. Each Investor acknowledges that Volt has entered into the Agreement in reliance upon, among other things, the commitment set forth herein.

Volt’s rights under paragraph 6(a) will terminate automatically and immediately upon the earliest to occur of: (i) the termination of the Merger Agreement in accordance with section 10.1 of the Merger Agreement; provided that, if Parent or Volt has made a claim hereunder or under the Merger Agreement, the foregoing rights will not terminate with respect to such claim unless and until such time as such claim is finally satisfied or otherwise resolved by agreement of the parties thereto or a final, non-appealable judgment of a Governmental Entity of competent jurisdiction or Volt accepts payment of the Parent Termination Fee, (ii) the Closing pursuant to the Merger Agreement, so long as the Subscriber has funded all amounts required to be funded by such Subscriber pursuant to Section 3.2.2(a) of the Partnership Agreement, or (iii) commencement by Volt of a lawsuit or other proceeding asserting any claim for payment under or in respect of the Merger Agreement, any Guarantee or the transactions contemplated by such Merger Agreement or thereby against any of the Subscriber Affiliates (as defined below), in each case other than (w) a lawsuit or other proceeding against the Subscriber (or its successors or permitted assignees) to specifically enforce the provisions in this paragraph 6, (x) a lawsuit or other proceeding against any Investor (as such term is defined in that certain Equity Commitment Letter, date as of the date hereof (as it may be amended, restated, waived or otherwise modified from time to time, the “Equity Commitment Letter”) (or such Investor’s successors or permitted assigns) to specifically enforce the obligations of such Investor under the Equity Commitment Letter, (y) a lawsuit or other proceeding against Energy Capital Partners III, LLC under the Confidentiality Agreement in accordance with its terms, or (z) a lawsuit or other proceeding against the Partnership (or its successors or permitted assignees) pursuant to section 11.11 of the Merger Agreement, or (iv) the Company accepts payment of the Parent Termination Fee pursuant to Section 10.3(b) of the Merger Agreement by Parent or by the Guarantor pursuant to the Guarantee in full and final satisfaction of all amounts in respect of such obligation.

The Partnership’s creditors shall have no right to enforce this paragraph 6 or to cause the General Partner, on behalf of the Partnership, to enforce this paragraph 6.  Capitalized terms used herein without definition either herein or in the Partnership Agreement have the meanings given to such terms in the Merger Agreement.  For the avoidance of doubt, the Subscriber will in no event be required to make Capital Contributions in connection with any Capital Call Notice issued by Volt pursuant to this paragraph 6 in excess of its then-existing Unused Capital Commitment.

The Partnership further agrees that neither it nor any of its affiliates shall have any right of recovery against the Subscriber or any of the Subscriber Affiliates, whether by piercing of the corporate veil, by a claim on behalf of the Partnership against the Subscriber or any of the Subscriber Affiliates, or otherwise, except for the Partnership’s right to be capitalized by the Subscriber under and to the extent provided in this Subscription Agreement and subject to the terms and conditions hereof. The Partnership hereby covenants and agrees that it shall not institute, and shall cause its affiliates not to institute, any proceeding or bring any other claim arising under, or in connection with, the Merger Agreement or the Merger (as defined therein) against the Subscriber or any Subscriber Affiliate except for claims against the Subscriber under this Subscription Agreement, under the Partnership Agreement or any side letter agreement; provided, however, that in the event that prior to the termination of this Subscription Agreement in accordance with its terms, Investor (i) consolidates with or merges with any other Person and is not the continuing or surviving entity of such consolidation or merger  or (ii) transfers or conveys all or a substantial portion of its properties and other assets to any Person such that the sum of the remaining net assets (excluding uncalled capital of Subscriber) is less than its portion of the Capital Commitment and the transferee thereof does not assume, directly or indirectly, Subscriber’s obligations hereunder, then, in each such case, each of the Partnership and Volt (as an express third party beneficiary hereunder) may seek recourse, whether by the enforcement of any judgment or assessment or by any legal or equitable proceeding or by virtue of any statute, regulation or other applicable law, against such continuing or surviving entity or such Person, as the case may be, but only to the extent of the liability of the Subscriber under this Subscription Agreement, under the Partnership Agreement or any side letter agreement.
