d.For purposes of this Agreement, “Cause” shall mean, the Employee’s: (i) commission of, and indictment for or formal admission to, a felony involving moral turpitude, deceit, dishonesty or fraud (but excluding traffic violations); (ii) willful and material misconduct or gross misconduct in connection with the performance of the Employee’s duties, including, without limitation, embezzlement or the misappropriation of funds or property of the Company; (iii) failure to adhere to lawful directions of the Chief Executive Officer, to adhere to the Company’s policies and practices, or as required in Section 2 hereof, to devote substantially all of the Employee’s business time and efforts to the Company, which failure continues for a period of 30 business days after written demand for corrective action is delivered by the Company; or (iv) material breach of the terms and provisions of this Agreement and the failure to cure such breach within 10 days following written notice from the Company specifying such breach.

e.For purposes of this Agreement, “Good Reason” shall mean any of the following, unless consented to by the Employee: (i) any change in job title or material diminution in the Employee’s roles and responsibilities from those set forth in this Agreement (including, without limitation, the assignment of duties materially inconsistent with Employee’s position) that cause a reduction in the Employee’s Annual Salary or Annual Bonus potential; (ii) a material reduction in the Employee’s Annual Salary or Annual

If a reduction of Section 280G Payments is necessary, the payments shall be reduced in the following order: (i) cash payments that are treated in full as a parachute payment; (ii) equity-based payments and accelerations of payments that are treated in full as a parachute payment; (iii) cash payments that are treated in part as a parachute payment; (iv) equity-based payments and accelerations of payments that are treated in part as a parachute payment; and (v) other non-cash forms of benefits. Within any such category of payments and benefits (that is, (i), (ii), (iii), (iv) or (v)), a reduction shall occur first with respect to amounts that are not “deferred compensation” within the meaning of Section 409A of the Code and then with respect to amounts that are “deferred compensation.” To the extent any such payment is to be made over time (e.g., in installments), the payments shall be reduced in reverse chronological order.

4.Company Policies. Employee acknowledges and agrees that he will carefully review each of the policies set forth in the Company Policy Handbook provided to the Employee

The Employee acknowledges that (i) the principal business of the Company (which expressly includes for purposes of this Section 9 (and any related enforcement provisions hereof), its successors and assigns) is to provide debt and equity financing for sustainable infrastructure projects that increase energy efficiency, provide cleaner energy sources, positively impact the environment and make more efficient use of natural resources (such businesses, and any and all other businesses in which, at the time of the Employee's termination, the Company is actively and regularly engaged or actively pursuing, herein being collectively referred to as the "Business"); (ii) the Company is one of the limited number of persons who have developed such a business; (iii) the Company's Business is North American in scope; (iv) the Employee's work for the Company has given and will continue to give him or her access to the confidential affairs and proprietary information of the Company; (v) the covenants and agreements of the Employee contained in this Section 9 are essential to the business and goodwill of the Company; and (vi) the Company would not have entered into this Agreement but for the covenants and agreements set forth in this Section 9. Accordingly, the Employee covenants and agrees that:

i.By and in consideration of the salary and benefits to be provided by the Company hereunder, including the severance arrangements set forth herein, and further in consideration of the Employee's exposure to the proprietary information of the Company, the Employee covenants and agrees that, during the period commencing on the date hereof and ending twelve (12) months following the date upon which the Employee shall cease to be an employee of the Company and its affiliates (the "Restricted Period"), the Employee shall not in the Restricted Territory (as defined below), directly or indirectly, whether as an owner, partner, shareholder, principal, agent, employee, consultant or in any other relationship or capacity, (A) engage in the Business (other than for the Company or its affiliates) or otherwise compete with the Company or its subsidiaries in the Business or (B) render to a person, corporation, partnership or other entity engaged in the Business the same services that the Employee renders to the Company; provided, however, that, notwithstanding the foregoing, (1) the

Employee may invest in securities of any entity, solely for investment purposes and without participating in the business thereof, if (x) such securities are listed on any national securities exchange, (y) the Employee is not a controlling person of, or a member of a group which controls, such entity, and (z) the Employee does not, directly or indirectly, own 5% or more of any class of securities of such entity; and (2) the Employee may continue to serve on any board of directors on which the Employee was serving as of the date of the Employee's termination of employment; and (3) the Employee may be employed by or provide services for a company (a "Conglomerate") with multiple lines of businesses, including a line of business competitive with the Company, so long as the following conditions are satisfied: (w) the Conglomerate derives less than ten percent (10%) of its total annual revenue from the line of business that is competitive with the Company (the "Competitive Division"), (x) the Employee is employed by or provides services to a line of business of Conglomerate that is not competitive with the Company; and (y) the Employee does not perform services for the Competitive Division; and (z) the Employee (A) provides the Company with advance notice of such employment or service and (B) informs the Conglomerate in writing of its obligations under this Section 9.

iii.During and after the Term, the Employee shall keep secret and retain in strictest confidence, and shall not use for the Employee’s benefit or the benefit of others, except in connection with the business and affairs of the Company and its affiliates, all non-public confidential matters relating to the Company's Business and the business of any of its affiliates and to the Company and any of its affiliates, learned by the Employee heretofore or hereafter directly or indirectly from the Company or any of its affiliates (the "Confidential Company Information"), and shall not disclose such Confidential Company Information to anyone outside of the Company except in the course of the Employee’s duties or with the CEO's express written consent. Confidential Company Information does not include information which is at the time of receipt or thereafter becomes publicly known through no wrongful act of the Employee or is received from a third party not under an obligation to keep such information confidential and without breach of this Agreement or which is independently developed or obtained by the Employee on the Employee's own time without reliance upon any confidential information of the Company or use of any Company resources. Notwithstanding anything in this agreement to the contrary, the Employee may disclose Confidential Company Information where the Employee is required to do so by law, regulation, court order, subpoena, summons

or other valid legal process; provided, that the Employee, so long as legally permitted to do so, first (A) promptly notifies the Company, (B) uses commercially reasonable efforts to consult with the Company with respect to and in advance of the disclosure thereof, and (C) reasonably cooperates with the Company to narrow the scope of the disclosure required to be made, in each case, solely at the Company’s expense.

iv.During the Restricted Period, the Employee shall not, without the Company's prior written consent, directly or indirectly, solicit or encourage to leave the employment or other service of the Company or any of its subsidiaries, any person or entity who is or was during the 6-month period preceding the Employee’s termination of employment, an employee, agent or independent contractor of the Company or any of its subsidiaries. During the Restricted Period, the Employee shall not, whether for the Employee’s own account or for the account of any other person, firm, corporation or other business organization, solicit for a competing business or intentionally interfere with the Company's or any of its subsidiaries’ relationship with, or endeavor to entice away from the Company for a competing business, any person who is or was during the 6-month period preceding the Employee's termination of employment, a customer, client, agent, or independent contractor of the Company or any of its subsidiaries. For purposes hereof, "customer" and "client," as such terms relate to government customers, mean the program office to which the Company is or was providing any goods or services as of the date hereof or during the one-year period prior to the date hereof.

v.All memoranda, notes, lists, records, property and any other tangible product and documents (and all copies thereof), whether visually perceptible, machine-readable or otherwise, made, produced or compiled by the Employee or made available to the Employee containing Confidential Company Information (A) shall at all times be the property of the Company (and, as applicable, any affiliates) and shall be delivered to the Company at any time upon its request, and (B) upon the Employee's termination of employment, shall be promptly returned to the Company. This section shall not apply to materials that the Employee possessed prior to the Employee’s business relationship with the Company, to the Employee's personal effects and documents, and to materials prepared by the Employee for the purposes of seeking legal or other professional advice.

vi.At no time during the Employee's employment by the Company or at any time thereafter shall the Employee or any representative of the Company publish any statement or make any statement under circumstances reasonably likely to become public that is critical of the other party, or in any way otherwise be materially injurious to the Business or reputation of the other party, unless otherwise required by applicable law or regulation or by judicial order.

vii.The Employee is hereby notified that 18 U.S.C. § 1833(b) states as follows: “An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that—(i) is made—(A) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Accordingly, notwithstanding any other provision of this Agreement to the contrary, the Employee has the right to (x) disclose in confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of the law or (y) disclose trade secrets in a document filed in a lawsuit or other proceeding so long as that filing is made under seal and protected from public disclosure. Nothing in this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b).

viii.The Employee understands that nothing contained in this Agreement limits the Employee's ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission (each, a "Government Agency"). The Employee further understands that this Agreement does not limit the Employee's ability to communicate with any Government Agency or with the Employee's attorney, including to report possible violations of federal law or regulation or making other disclosures that are protected under the whistleblower provisions of federal law or regulation, or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company.

b.Rights and Remedies upon Breach.

i.The parties hereto acknowledge and agree that any breach of any of the provisions of Section 9 or any subparts thereof (individually or collectively, the "Restrictive Covenants") may result in irreparable injury and damage for which money damages would not provide an adequate remedy. Therefore, if either party breaches, or threatens to commit a breach of, any of the provisions of Section 9 or any subpart thereof, the other party and its affiliates, in addition to, and not in lieu of, any other rights and remedies available to the other party and its affiliates under law or in equity (including, without limitation, the recovery of damages), shall have the right and remedy to seek to have the Restrictive Covenants or other obligations herein specifically enforced (without posting bond and without the need to prove damages) by any court having equity jurisdiction, including, without limitation, the right to seek an entry of restraining orders and injunctions (preliminary, mandatory, temporary and permanent) against violations, whether or not then continuing, of such covenants.

ii.The Employee agrees that the provisions of Section 9 of this Agreement and each subsection thereof are reasonably necessary for the protection of the Company’s legitimate business interests and if enforced, will not prevent the Employee from obtaining gainful employment should the Employee’s employment with the Company end. The Employee agrees that in any action seeking specific performance or other equitable relief, the Employee will not assert or contend that any of the provisions of this Section 9 are unreasonable or otherwise unenforceable as drafted. The existence of any claim or cause of action by the Employee, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement of the Restrictive Covenants.

c.The provisions of this Paragraph 9 will survive any termination of this Agreement.

5.Notices. All notices and other communications required or permitted under this Agreement shall be in writing, served personally on, or mailed by registered or certified United States mail to, in the case of notices to the Employee, to the Employee’s residence set forth in the employment records of the Company and in the case of notices to the Company, to the Company’s principal executive office to the attention of the Chief Legal Officer.

6.Section 409A.

(a)To the extent applicable, it is intended that this Agreement comply with the provisions of Section 409A of the Code, and this Agreement shall be construed and applied in a manner consistent with this intent. If the consideration and revocation period set forth in Section 7(f) hereof spans two taxable years, payments will be made in the second taxable year.

(b)Any payment or benefit due upon a termination of employment that represents a "deferral of compensation" within the meaning of Section 409A shall commence to be paid or provided to Employee thirty-one (31) days following a "separation from service" as defined in Treas. Reg. Section 1.409A-1(h), unless earlier commencement is otherwise permitted by Section 409A, provided that Employee executes within 30 days following "separation from service" a general release of claims in a form and substance satisfactory to the Company and its legal counsel. Each payment made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A. Amounts payable under this Agreement shall be deemed not to be a "deferral of compensation" subject to Section 409A to the extent provided in the exceptions in Treasury Regulation Section 1.409A-1(b)(4) ("short-term deferrals") and (b)(9) ("separation pay plans," including the exception under subparagraph (iii)) and other applicable provisions of Treasury Regulation Sections 1.409A-1 through A-6.

(c)Notwithstanding anything in this Agreement to the contrary, the following special rule shall apply, if and to the extent required by Section 409A, in the event that (i) Employee is deemed to be a "specified employee" within the meaning of Section 409A(a)(2)(B)(i), (ii) amounts or benefits under this Agreement or any other program, plan or arrangement of the Company or a controlled group affiliate thereof are due or payable on account of "separation from service" within the meaning of Treasury Regulations Section 1.409A-1(h), and (iii) Employee is employed by a public company or a controlled group affiliate thereof: no payments hereunder that are "deferred compensation" subject to Section 409A shall be made to Employee prior to the date that is six (6) months after the date of separation from service or, if earlier, the date of death; following any applicable six (6) month delay, all such delayed payments will be paid in a single lump sum on the earliest permissible payment date.

Notwithstanding anything to the contrary in this Agreement, any payment or benefit under this Agreement or otherwise that is exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9)(v)(A) or (C) (relating to certain reimbursements and in-kind benefits) shall be paid or provided to Employee only to the extent that the expenses are not incurred, or the benefits are not provided, beyond the last day of the second calendar year following the calendar year in which Employee's "separation from service" occurs; and provided further that such expenses are reimbursed no later than the last day of the third calendar year following the calendar year in which Employee's "separation from service" occurs. To the extent any indemnification payment, expense reimbursement or the provision of any in-kind benefit is determined to be subject to Section 409A (and not exempt pursuant to the prior sentence or otherwise), the amount of any such indemnification payment or expenses eligible for reimbursement or the provision of any in-kind benefit in one calendar year shall not affect the indemnification payment or provision of in-kind benefits or expenses eligible for reimbursement in any other calendar year (except for any lifetime or other aggregate limitation applicable to medical expenses), and in no event shall any indemnification payment or expenses be reimbursed after the last day of the calendar year following the calendar year in which Employee incurred such indemnification payment or expenses, and in no event shall any right to indemnification payment or reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit.

6.Entire Agreement. This Agreement contains the entire understanding between the parties and supersedes any prior written or oral agreements between them. There are no representations, warranties, covenants, agreements or understandings oral or written, between the parties relating to the employment of the Employee which are not fully expressed herein. This Agreement shall not be modified or waived except by written instrument and signed by the parties.

7.Severability. The provisions of this Agreement shall be deemed severable, and if any part of any provision is held by any court of competent jurisdiction to be illegal, void, invalid or unenforceable in whole or in part as to any party, such provision may be changed, consistent with the intent of the parties hereto, to the extent reasonably necessary to make such provision,

as so changed, legal, valid, binding and enforceable. If such provision cannot be changed consistent with the intent of the parties hereto to make it legal, valid, biding and enforceable, then such provision shall be stricken from this Agreement, and the remaining provisions of this Agreement shall not be affected or impaired but shall remain in full force and effect.

8.Binding Effect. This Agreement shall inure to the benefit of and be binding upon the parties and their respective executors, administrators, personal representatives, heirs, legatees, devises, assigns and successors in interest.

9.Governing Law. This Agreement has been entered into in, and shall be construed and enforced in accordance with, the laws of the State of Maryland, without giving effect to the principles of conflicts of law thereof.

10.Counterparts; Effectiveness. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same Agreement. This Agreement will become effective when the Company receives a counterpart hereof executed by the Employee and the Company.

    IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written.
