Employment Agreement, dated March 1, 2019, by and between Hannon Armstrong Sustainable Infrastructure Capital, Inc. and Jeffrey A. Lipson

Term. The Company hereby agrees to employ the Employee, and the Employee hereby agrees to work for the Company, on the terms and conditions hereinafter set forth. The term of this Agreement will commence as of the start date of March 1, 2019 (the “Commencement Date”) and terminate on a date specified by the Company or the Employee in a notice given, at will, with or without Cause (as defined below), by either party to the other not less than 30 days prior to such date, unless such term is sooner terminated as herein provided.

Duties. The Employee agrees to be employed by the Company in such capacities as the Company may from time to time direct, it being the intent of the parties that the Employee will serve in the capacity of Executive Vice President, Chief Financial Officer and Treasurer, and as such, the Employee shall faithfully perform for the Company the duties of such office and shall have such responsibilities as are customary for an Executive Vice President and Chief Financial Officer employed by a public company of similar size and nature. The Employee shall report directly to the Chief Executive Officer of the Company. During the term of this Agreement, the Employee will devote his full time and exclusive attention during normal business hours to, and use his best efforts to advance, the business and welfare of the Company, its affiliates, subsidiaries and successors in interest. During the term of his employment with the Company, the Employee shall not engage in any other employment activities for any third party for any direct or indirect remuneration without the prior written consent of the Company. It is acknowledged hereunder that Employee currently serves as a Director of Congressional Bank for which he receives compensation, and such service has been approved by the Company.

Compensation. For all services provided by the Employee, the Company shall compensate Employee in such amounts and upon such terms as the parties may agree from time to time. The initial Base Salary and Annual Bonus amounts set forth in Exhibit A attached hereto are made a part of this Agreement. The Compensation Committee of the Board (the “Compensation Committee”) shall review the Employee’s Base Salary and Annual Bonus in good faith on an annual basis and may provide for increases or decreases thereto, and shall set the criteria for earning such Annual Bonus, as it may in its sole discretion deem appropriate.

Other Benefits. During the term of employment with the Company, the Employee will be eligible to participate in fringe benefit programs that the Company generally makes available to its employees, including medical and dental insurance and life insurance; provided that nothing herein shall be construed as restricting the Company’s right to unilaterally modify or terminate any of such programs at any time with or without notice. Without limiting the generality of this Section 4, the Employee shall be entitled to paid vacation of 20 business days per year (to be taken at reasonable times in accordance with the Company’s policies).

Equity Awards. The Employee will be eligible to receive an award of limited partner profit interests (“LTIP Units”) under the 2013 Hannon Armstrong Sustainable Infrastructure Capital, Inc. Equity Incentive Plan (the "Equity Incentive Plan") and an appropriate LTIP Unit award agreement when grants of LTIP Units are otherwise made by the Company to similarly situated executives of the Company. In the event that the Company terminates the Employee’s employment with the Company other than for Cause within 60 days before or 90 days after a Change in Control (as defined in the Equity Incentive Plan), all of the Employee’s (A) LTIP Units, (B) shares of restricted stock and (C) other stock-based compensation that were granted under the Equity Incentive Plan or any successor plan and that are outstanding at the time of such termination shall become fully vested and nonforfeitable.

Death or Disability. If the Employee dies or becomes totally disabled during the term of his employment, the Employee’s employment with the Company will automatically terminate and all obligations of the Company hereunder will terminate as of the end of the month in which such event occurs.        

Certain Terminations of Employment.

In the event that (i) the Company terminates the Employee’s employment with the Company for Cause, (ii) the Employee terminates the Employee’s employment with the Company for any reason or (iii) the Employee’s employment with the Company is terminated by reason of death or disability pursuant to Section 6, the Company shall pay to the Employee (or the Employee’s estate or beneficiaries), in a lump sum payment within 30 days following the effective date the Employee’s termination of employment, an amount equal to the Base Salary, Annual Bonus and other benefits earned and accrued under this Agreement but not yet paid prior to the effective date of termination (collectively, the “Accrued Benefits”).

In the event that the Company terminates the Employee’s employment with the Company for reasons other than for Cause, the Company shall pay to the Employee severance compensation in a lump sum payment within 30 days following the effective date the Employee’s termination of employment in an amount equal to (i) the Accrued Benefits, (ii) the then-current monthly Base Salary payable under paragraph 3 hereof, as of the date of termination, for the nine (9) months following the date of termination, and (iii) 75% of the Employee’s average Annual Bonus payable under paragraph 3 hereof actually received in respect of the three fiscal years (or such fewer number of fiscal years with respect to which the Employee received an Annual Bonus) prior to the year of termination.

In the event that the Company terminates the Employee’s employment with the Company for reasons other than for Cause, the Company shall provide, for the period beginning on the date of the termination of the Employee's employment with the Company and ending on the earlier of (x) twelve (12) months following the Employee's termination employment and (y) the date on which the Employee's coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), terminates as provided by law (and the Employee shall notify the Company of any subsequent employment through which he is provided medical coverage), Company-paid medical coverage at the same rates as in effect prior to the date of termination of Employee's employment (so long as applicable law and regulations permit such Company payment without imposition of a tax or penalty on the Company or other plan participants or otherwise adversely affecting the Company, the applicable plan or other participants in the plan), or, at the Company's option, the cash amount necessary to obtain equivalent coverage.

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.

Notwithstanding any other provision of this Agreement, the Company shall not be required to provide the payments and benefits provided for under Sections 7(b) and (c) unless the Employee executes and delivers to the Company a waiver and release substantially in the form attached hereto as Exhibit B and such waiver and release becomes effective and irrevocable within 21 days following the date of termination.

Company Policies. The Employee acknowledges and agrees that he will carefully review each of the policies set forth in the Company Policy Handbook provided to the Employee and will acknowledge his review and acceptance of such policies and the obligations required of the Employee by signing the applicable signature blocks therein and returning the executed version to the Office of the General Counsel. Employee likewise acknowledges and agrees to abide by any revision or addition to the Company policies as may be issued by the Company from time to time throughout the term of employment.

Restrictive Covenants.

Covenants. 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 national in scope; (iv) the Employee's work for the Company has given and will continue to give him 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:

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 nine (9) 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, (i) 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 (ii) 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, (A) 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 (B) 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 (C) 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.

For purposes of this Agreement, the "Restricted Territory" shall mean any (i) state in the United States and (ii) foreign country or jurisdiction, in the case of clause (i) or (ii), in which the Company (x) is actively conducting the Business during the Term or (y) has initiated a plan adopted by the Board to conduct the Business in the two years following the Term.

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 (i) promptly notifies the Company, (ii) uses commercially reasonable efforts to consult with the Company with respect to and in advance of the disclosure thereof, and (iii) 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.

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.

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 (i) 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 (ii) 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.

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.

Rights and Remedies upon Breach.

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.

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.

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

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 General Counsel.

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.

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.

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.

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.

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.
