Agreement constitutes the valid, legal and binding obligations of the Parent, enforceable against the Parent in accordance with its terms, subject to bankruptcy and similar laws affecting the remedies or resources of creditors generally and
principles of equity. The execution and delivery of this Agreement and the consummation of the transactions contemplated herein will not conflict with, or result in any violation of, or default (with or without notice or lapse of time or both)
under, give rise to a right of termination, cancellation or acceleration of, or give any Person the right to exercise any remedy under, any contractual obligation, under: (i) any agreement, order or decree to which the Parent is a party or such
Person is bound or to which any of such Person’s assets are subject, (ii) the Organizational Documents of the Parent, or (iii) any law applicable to the Parent. Other than as may be required for the consummation of the initial public
offering of the Common Stock and the actions to be take in connection therewith, no authorization, approvals or consents from, or registration, declaration or filings with, any lender, partner, member, stockholder, beneficiary, tenant, creditor,
investor, Authority or other Person is required in order for the Parent to execute and deliver this Agreement and consummate the transactions contemplated herein. 
 (c) No Consents. Other than as may be required for the consummation of the initial public offering of the Common Stock and the actions to be taken in connection therewith, no consent, waiver,
approval, authorization, order, license, permit or registration of, qualification, designation, declaration or filing with, any Person or Governmental Authority or under any applicable Laws is required to be obtained by Parent in connection with the
execution, delivery and performance of this Agreement and the transactions contemplated hereby and thereby, except for those consents, waivers, approvals, authorizations, orders, licenses, permits, registrations, qualifications, designations,
declarations or filings, the failure of which to obtain or to file would not, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect. 

Section 4.03. Representations and Warranties of the Operating Partnership. The Operating Partnership hereby represents and
warrants to Fund III, as of the date of this Agreement and the Closing Date, as follows: 
 (a) Existence and
Power. The Operating Partnership has been duly formed and validly exists as a limited partnership under the laws of the State of Delaware. The Operating Partnership has all power and authority to enter into this Agreement and all other
documents to be executed and delivered in connection with the transactions that are the subject of this Agreement, and to perform its obligations in connection with the transactions that are the subject of this Agreement. 

(b) Authorization; No Contravention. The execution and delivery of this Agreement by the Operating Partnership and the performance
of its obligations hereunder have been duly authorized by all requisite action, and all necessary authorizations, consents, approvals, elections and waivers have been obtained as of the Closing Date. This Agreement constitutes the

valid, legal and binding obligations of the Operating Partnership, enforceable against the Operating Partnership in accordance with its terms, subject to bankruptcy and similar laws affecting the
remedies or resources of creditors generally and principles of equity. The execution and delivery of this Agreement and the consummation of the transactions contemplated herein will not conflict with, or result in any violation of, or default (with
or without notice or lapse of time or both) under, give rise to a right of termination, cancellation or acceleration of, or give any Person the right to exercise any remedy under, any contractual obligation, under: (i) any agreement, order or
decree to which the Operating Partnership is a party or such Person is bound or to which any of such Person’s assets are subject, (ii) the Organizational Documents of the Operating Partnership, or (iii) any law applicable to the
Operating Partnership. No authorization, approvals or consents from, or registration, declaration or filings with, any lender, partner, member, stockholder, beneficiary, tenant, creditor, investor, Authority or other Person is required in order for
the Operating Partnership to execute and deliver this Agreement and consummate the transactions contemplated herein. 
 (c)
No Consents. No consent, waiver, approval, authorization, order, license, permit or registration of, qualification, designation, declaration or filing with, any Person or Governmental Authority or under any applicable Laws is required to be
obtained by the Operating Partnership in connection with the execution, delivery and performance of this Agreement and the transactions contemplated hereby and thereby, except for those consents, waivers, approvals, authorizations, orders, licenses,
permits, registrations, qualifications, designations, declarations or filings, the failure of which to obtain or to file would not, individually or in the aggregate, reasonably be expected to have a OP Material Adverse Effect. 

(d) OP Units. The OP Units to be received in connection with the Contribution have been duly authorized for issuance and, upon
such issuance, will be validly issued and fully paid. 
 ARTICLE V 

DEFAULTS AND REMEDIES 
 Section 5.01. Default by Fund III. If the Closing is not consummated because of a default by Fund III under this Agreement, then the Parent and the Operating Partnership may either
(i) seek specific performance of this Agreement by requiring Fund III to assign the LLC Equity Interests to the Operating Partnership and in connection therewith Fund III shall reimburse the Parent and the Operating Partnership for the actual
out-of-pocket expenses incurred by the Parent or the Operating Partnership in connection with seeking such specific performance, or (ii) terminate this Agreement in full and, except as expressly set forth elsewhere in this Agreement, no party
hereto shall thereafter have any obligation under any provision of this Agreement.

 ARTICLE VI 
 INDEMNIFICATION 
 Section 6.01. Indemnification. Subject to the
limitations provided below, from and after the Closing Date, Fund III agrees to indemnify, defend and hold harmless each of the Indemnified Parties from and against all Losses that are incurred or suffered by any of them based upon, arising out of,
in connection with or by reason of (i) the breach of any of the representations or warranties of Fund III under this Agreement or (ii) any breach by Fund III of its obligations under this Agreement; provided, however, that the
maximum aggregate liability of the Indemnifying Party under this Section 7.01 shall not exceed $1,000,000. Fund III’s indemnification obligation pursuant to this Section 7.01 shall be secured by a pledge of the LLC Equity Interests in
accordance with the terms and conditions of a pledge agreement to be entered into between the Parent and Fund III. 

Section 6.02. Method of Asserting Claims. All claims for indemnification by any Indemnified Party under this Article VI shall
be asserted and resolved as follows: 
 (a) If an Indemnified Party intends to seek indemnification under this Article VI, it
shall promptly notify Fund III in writing of such claim. The failure to provide such notice will not affect any rights hereunder except to the extent Fund III is materially prejudiced thereby. 

(b) If such claim involves a claim by a third-party against the Indemnified Party, Fund III shall, within ten days after receipt of such
notice and upon notice to the Indemnified Party, assume, with counsel reasonably satisfactory to the Indemnified Party, at the sole cost and expense of Fund III, the settlement or defense thereof (in which case any Loss associated therewith shall be
the sole responsibility of Fund III), provided that the Indemnified Party may participate in such settlement or defense through counsel chosen by it. If the Indemnified Party determines in good faith that representation by Fund III’s counsel of
(i) the Indemnifying Party and (ii) the Indemnified Party may present such counsel with a conflict of interest, then Fund III shall pay the reasonable fees and expenses of the Indemnified Party’s counsel. Notwithstanding the
foregoing, (i) the Indemnified Party may, at the sole cost and expense of Fund III, at any time prior to the delivery of the notice referred to in the first sentence of this Section 6.02(b) by Fund III, file any motion, answer or other
pleadings or take any other action that the Indemnified Party reasonably believes to be necessary or appropriate to protect its interests, (ii) the Indemnified Party may take over the control of the defense or settlement of a third-party claim
at any time if it irrevocably waives its right to indemnity under this Article VI with respect to such claim and (iii) Fund III may not, without the consent of the Indemnified Party, settle or compromise any action or consent to the entry of
any judgment. So long as Fund III is contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim without Fund III’s consent, such consent not to be unreasonably withheld. Notwithstanding the foregoing,
if the compromise or settlement of a third-party claim could reasonably be expected to adversely affect the status of the Parent as a real estate investment trust within the meaning of Section 856 of the Code, then the Parent shall make such
decision to compromise or settle the third-party claim without the need to obtain the other 

  
 - 15 -









 
party’s consent. If Fund III is not entitled to assume the defense of the claim pursuant to the foregoing provisions or is entitled but does not contest such claim in good faith (including
if Fund III does not notify the Indemnified Party of its assumption of the defense of such claim within the ten-day period set forth above), then the Indemnified Party may conduct and control, through counsel of its own choosing and at the expense
of Fund III, the settlement or defense thereof, and Fund III shall cooperate with it in connection therewith. The failure of the Indemnified Party to participate in, conduct or control such defense shall not relieve Fund III of any obligation it may
have hereunder. Any defense costs required to be paid by Fund III shall be paid as incurred, promptly against delivery of invoices therefor. 
 Section 6.03. Survival. This Article VI shall survive until six months following the Closing or the termination of the parties’ obligations to consummate the transactions
contemplated by this Agreement. Except as provided otherwise in this Agreement, all representations and warranties contained in this Agreement shall survive the Closing for a period of one-year and shall not be deemed to be merged into or waived by
the instruments of the Closing. 
 Section 6.04. Waiver of Claims. Deliverance of the OP Units provided in this
Agreement shall serve to waive all claims against the Parent, the Operating Partnership and Hannon LLC. 
 Section 6.05.
Character of Indemnity Payments. The parties agree that any indemnification payments made with respect to this Agreement shall be treated for all Tax purposes as an adjustment to the Contribution Consideration, unless otherwise required by
law (including by a determination of a Tax Authority that, under applicable law, is not subject to further review or appeal). If an indemnification payment by law cannot be treated as an adjustment to the Contribution Consideration, the Indemnifying
Party will pay an amount to the Indemnified Party that reflects the hypothetical Tax consequences of the receipt or accrual of such indemnification payment, using the maximum applicable statutory rate (or, in the case of an item that affects more
than one Tax, rates) of Tax and reflecting, for example, the effect of deductions available for Taxes such as state and local income Taxes. 
 ARTICLE VII 
 MISCELLANEOUS 

Section 7.01. Marketing. Fund III shall not market the LLC Equity Interests for sale or entertain or discuss any offer to
purchase or acquire the LLC Equity Interests with any Person other than the Parent, the Operating Partnership and their Affiliates unless this Agreement is terminated in accordance with the terms set forth in Section 2.04.

 Section 7.02. Entire Agreement; No Amendment. This Agreement and the
Registration Rights Agreement represents the entire agreement among each of the parties hereto with respect to the subject matter hereof. It is expressly understood that no representations, warranties, guarantees or other statements shall be valid
or binding upon a party unless expressly set forth in this Agreement or the Registration Rights Agreement. It is further understood that any prior agreements or understandings between the parties with respect to the subject matter hereof have merged
in this Agreement and the Registration Rights Agreement which fully expresses the entire agreement of the parties hereto as to the subject matter hereof and supersedes all such prior agreements and understandings. This Agreement may not be amended,
modified or otherwise altered except by a written agreement signed by the party hereto against whom enforcement is sought. 

Section 7.03. Certain Expenses. Except as otherwise agreed by the parties herein, each party hereto will pay all of its own
expenses incurred in connection with this Agreement and the transactions contemplated hereby (whether or not the Closing shall take place), including, without limitation, all costs and expenses herein stated to be borne by such party and all of its
respective accounting, legal, investigatory and appraisal fees. 
 Section 7.04. Transfer Taxes. All transfer,
registration, stamp, documentary, sales, use and similar Taxes (including all applicable real estate transfer or gains Taxes and transfer Taxes), any penalties, interest and additions to Tax, and fees incurred in connection with the Contribution
shall be the responsibility of and be timely paid 50% by Fund III, on one hand, and 50% by the Operating Partnership, on the other hand. Fund III and the Operating Partnership shall cooperate in the timely making of all filings, returns, reports and
forms as may be required in connection therewith. 
 Section 7.05. Power of Attorney. 

(a) By executing this Agreement, Fund III hereby irrevocably appoints the Parent (or its designee) and any successor thereof from time to
time (such Parent or designee or any such successor of any of them acting in his, her or its capacity as attorney-in-fact pursuant hereto, the “Attorney-in-Fact”) as the true and lawful attorney-in-fact and agent of Fund III, to act
in the name, place and stead of Fund III to make, execute, acknowledge and deliver all assignments, contracts, orders, receipts, notices, requests, instructions, certificates, consents, letters and other writings (including, without limitation,
(i) the execution of any documents relating to the Contribution or the initial public offering of the Common Stock, and (ii) to provide information to the Securities and Exchange Commission and others about the transactions contemplated
hereby) and, in general, to do all things and to take all actions which the Attorney-in-Fact in its sole discretion may consider necessary or proper in connection with or to carry out the transactions contemplated by this Agreement as fully as could
Fund III if personally present and acting (the “Power of Attorney”). 

  
 - 17 -









 (b) The Power of Attorney and all authority granted hereby shall be coupled with an interest
and therefore shall be irrevocable and shall not be terminated by any act of Fund III, and if any other such act or events shall occur before the completion of the transactions contemplated by this Agreement, the Attorney-in-Fact nevertheless shall
be authorized and directed to complete all such transactions as if such other act or events had not occurred and regardless of notice thereof. Fund III hereby authorizes the reliance of third parties on the Power of Attorney. 

Section 7.06. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been
duly given if personally delivered with proof of delivery thereof (any notice or communication so delivered being deemed to have been received at the time delivered), or sent by United States certified mail, return receipt requested, postage prepaid
(any notice or communication so sent being deemed to have been received two Business Days after mailing in the United States), with failure or refusal to accept delivery to constitute delivery for all purposes of this Agreement, addressed to the
respective parties as follows: 
 If to Fund III or the Splitter Partnership, to the address listed on Fund III or the Splitter
Partnership’s signature page to this Agreement. 
 If to the Parent or the Operating Partnership, to:

 Section 7.07. No Assignment. Except as provided in this Section below, neither this Agreement nor any of the rights or obligations hereunder may be assigned by any party hereto without the
prior written consent of the other parties. 
 Section 7.08. Governing Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of
any jurisdiction other than those of the State of Delaware.

 Section 7.09. Multiple Counterparts. This Agreement may be executed in multiple
counterparts. If so executed, all of such counterparts shall constitute but one agreement, and, in proving this Agreement, it shall not be necessary to produce or account for more than one such counterpart. To facilitate execution of this Agreement,
the parties may execute and exchange by facsimile or electronic mail PDF copies of counterparts of the signature pages. 

Section 7.10. Further Assurances. From and after the date of this Agreement and after the Closing, the parties hereto shall
take such further actions and execute and deliver such further documents and instruments as may be reasonably requested by the other parties and are reasonably necessary to provide to the respective parties hereto the benefits intended to be
afforded hereby, including, without limitation, all books and records relating to the LLC Equity Interests. 

Section 7.11. Miscellaneous. Whenever herein the singular number is used, the same shall include the plural, and the plural
shall include the singular where appropriate, and words of any gender shall include the other gender when appropriate. The headings of the Articles and the Sections contained in this Agreement are for convenience only and shall not be taken into
account in determining the meaning of any provision of this Agreement. The words “hereof” and “herein” refer to this entire Agreement and not merely the Section in which such words appear. If the last day for performance of any
obligation hereunder is not a Business Day, then the deadline for such performance or the expiration of the applicable period or date shall be extended to the next Business Day. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective heirs, legal representatives, successors and assigns. The Exhibits attached hereto are hereby incorporated herein and shall be deemed a part of this Agreement. 

Section 7.12. Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid or unenforceable under
present or future laws, such provision shall be fully severable, this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions of this
Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. 
 Section 7.13. Attorneys’ Fees. If this Agreement or the transactions contemplated herein give rise to a lawsuit, arbitration or other legal proceeding between the parties hereto, the
prevailing party shall be entitled to recover its costs and reasonable attorney fees in addition to any other judgment of the court or arbitrator(s).

applicable law, the parties hereto waive trial by jury in any action, proceeding or counterclaim brought by any party(ies) against any other party(ies) on any matter arising out of or in any way connected with this Agreement or the relationship of
the parties created hereunder.
