 HA Land Lease Holdings, LLC, a Delaware limited liability company (the “Depositor”) will sell certain assets to the
Issuer pursuant to a Contribution and Sale Agreement, dated as of September 30, 2015, by and among the Issuer and the Depositor (the “Sale Agreement”). 

This Agreement and all other Transaction Documents are dated as of the date hereof (the “Closing Date”) and the sale and
purchase of the Bonds contemplated hereby is occurring on the Closing Date. 
 For good and valuable consideration, the Issuer hereby agrees
with each Purchaser as follows: 
 Section 2. Purchase, Sale, Payment and Delivery of the Bonds. The sale and purchase of
the Bonds to be purchased by each Purchaser is occurring on the date hereof at the offices of Akin Gump Strauss Hauer & Feld LLC, One Bryant Park, New York, New York 10024, at 10:00 a m., New York City time. On the date hereof, the Issuer
will deliver to each Purchaser the Bonds to be purchased by such Purchaser in the form of a single Bond (or such greater number of Bonds in denominations of at least $250,000 as such Purchaser may request) dated the Closing Date and registered in
such Purchaser’s name (or in the name of its nominee), against delivery by such Purchaser to the Issuer or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for
the account of the Issuer to account number              at The Bank of New York Mellon, 101 Barclay Street - 7W, New York, NY 10286, ABA# 021-000-018, account name: HASI SYB Tr 2015 1
Collection Acc. If on the Closing Date the Issuer shall fail to tender such Bonds to any Purchaser as provided above in this Section 2, or any of the conditions specified in Section 6 shall not have been fulfilled to such
Purchaser’s satisfaction or waived by such Purchaser, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement without thereby waiving any rights such Purchaser may have by reason of any of the
conditions specified in Section 6 not having been fulfilled to such Purchaser’s satisfaction or such failure by the Issuer to tender such Bonds. Schedule 1 hereto sets forth the name of each Purchaser, its address, the principal
amount of Bonds being purchased by such Purchaser and the purchase price being paid therefor by wire transfer on the date hereof. 

Section 3. Representations, Warranties and Covenants of the Issuer. The Issuer represents, warrants, covenants and agrees
with each Purchaser that, as of the Closing Date: 
 (a) The Issuer is a statutory trust duly formed, organized and existing under the laws
of the state of Delaware and has the full legal right, power and authority to (i) adopt the resolutions authorizing the issuance of the Bonds, (ii) enter into the Transaction Documents (defined below) to which it is a party and to carry
out the terms thereof, (iii) issue, sell and deliver the Bonds to Purchasers as provided herein and (iv) carry out and consummate the transactions as to the Bonds on its part contemplated by the Transaction Documents to which it is a
party. 







 (b) All necessary official action has been taken by the Issuer with respect to, and the Issuer
has duly authorized and approved the adoption or execution and delivery by the Issuer of, and the performance by the Issuer of its obligations under, the Transaction Documents to which it is a party, and the related authorizing resolutions and such
authorizations and approvals are in full force and effect and have not been amended, modified or rescinded. The Bonds have been duly authorized by the Issuer and, when the Bonds are authenticated, delivered and paid for pursuant to this Agreement,
such Bonds will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Issuer entitled to the benefits provided by the Indenture, and enforceable in accordance with terms and
conditions therein, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect affecting the enforcement of creditors rights in general, and except as such
enforceability may be limited by general principles of equity (whether considered in a suit at law or in equity). When executed and delivered by the Issuer, each of the Transaction Documents to which it is a party will constitute the legal, valid
and binding obligation of the Issuer enforceable in accordance with its terms, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect affecting the enforcement of
creditors rights in general, and except as such enforceability may be limited by general principles of equity (whether considered in a suit at law or in equity). 

(c) Assuming that the representations, warranties and covenants of each Purchaser contained in this Agreement are true and correct in all
material respects and have been and will be complied with in all material respects and that the Bonds are offered and sold in accordance with the final Private Placement Memorandum (including the Appendices thereto), dated as of September 29,
2015 (the “Final PPM”), and the applicable Transaction Documents (as defined below), no registration of the Bonds under the Securities Act is required for the offer, sale and delivery of the Bonds at the time and in the manner
contemplated by this Agreement and the Indenture. 
 (d) All of the representations and warranties made by the Issuer in the Transaction
Documents to which Issuer is a party are true and correct in all material respects as of the Closing Date. 
 Section 4.
Representations, Warranties and Covenants of the Depositor, made on behalf of the Issuer. The Depositor, on behalf of the Issuer, represents, warrants, covenants and agrees with each Purchaser that, on the Closing Date: 

(a) The Issuer is not in breach of or in default under any applicable constitutional provision, law or administrative rule or regulation, or
any agency or department, or its organizational or corporate documents, or any applicable judgment or decree or any trust agreement, loan agreement, indenture, bond, note, resolution, ordinance, agreement or other instrument to which the Issuer is a
party or to which the Issuer or any of its properties or other assets is otherwise subject, and no event has occurred and is continuing which, with the passage of time or the giving of notice, or both, would constitute a default or event of default
under any such instrument which breach, default or event could have an adverse effect on the Issuer’s ability to perform its obligations under the Transaction Documents; and, as of such times, the authorization, execution and delivery of the
Transaction Documents and compliance by the Issuer with the obligations on its part to be performed in each of such agreements or instruments does not and will not conflict with or constitute a breach of or default under any applicable
constitutional provision, law or administrative rule or regulation of the State of Delaware or the United States of America, or any agency or department of either, or the Issuer’s organizational documents, or any applicable judgment, decree,
license, permit, trust agreement, loan agreement, indenture, bond, note, resolution, ordinance, agreement or other instrument to which the Issuer (or any of its officers in their respective capacities as such) is subject, or by which it or any of
its properties is bound, nor will any such authorization, execution, delivery or compliance result in the creation or imposition of any lien, charge or other security interest or encumbrance of any nature whatsoever upon any of its assets or
properties or under the terms of any such law, regulation or instrument, except as may be provided by the Transaction Documents. 
 (b) The
Issuer, through its agent, Hannon Armstrong Capital, LLC, has delivered to each Purchaser a copy of the Final PPM (the Final PPM, together with the Transaction Documents, the “Offering 

  
 2 








 
Materials”), relating to the securitization transaction contemplated by the Transaction Documents. The Offering Materials fairly describe, in all material respects, the general nature
of the business and principal assets of the LLE Subsidiaries of the Issuer. The Offering Materials, taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. 
 (c) Schedule 2 hereto contains (except as noted therein)
a complete and correct list of all of the Issuer’s subsidiaries, showing, as to each Land Lease Entity, the name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity
interests outstanding owned by the Issuer and, as to the Issuer, the Issuer’s directors and senior officers. Each Land Lease Entity is wholly-owned directly by the Issuer. There are no outstanding contracts, options, warrants, instruments,
documents or agreements binding upon the Depositor or Issuer granting to any Person or group of Persons any right to purchase or acquire equity interests in any Land Lease Entity. 

(d) All of the outstanding equity interests of each Land Lease Entity shown in Schedule 2 hereto have been contributed and sold to the
Issuer, free and clear of any Lien other than Permitted Liens. 
 (e) There is no action, suit or proceeding at law or in equity, before or
by any court, government agency, public board or body (collectively and individually, an “Action”) pending with respect to which the Issuer has been served with process or, to the knowledge of the Issuer, threatened, which Action
(i) in any way questions the corporate existence of the Issuer or the titles of the officers of the Issuer to their respective offices, (ii) affects, contests or seeks to prohibit, restrain or enjoin any of the transactions contemplated by
the Transaction Documents, or the payment or collection of any amounts pledged or to be pledged to pay the principal of and interest on the Bonds, or in any way contests or affects the validity or enforceability of the Transaction Documents or the
consummation of the transactions on the part of the Issuer contemplated thereby, or (iii) may result in any material adverse change in the business, properties, other assets or financial condition of the Issuer; and as of the time of acceptance
hereof, to the knowledge of the Issuer, there is no basis for any action, suit or proceeding of the nature described in clauses (i) through (iii) of this sentence. 

(f) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority required for the due
execution, delivery or performance by the Issuer of any Transaction Document to which it is a party remains unobtained or unfiled or unrecorded except such as may be required under state securities or blue sky laws in any jurisdiction in connection
with the purchase and sale of the Bonds by a Purchaser. All official action of the Issuer relating to the Transaction Documents taken as of the date hereof pertaining to the Bonds shall be in full force and effect and shall not have been amended,
modified or supplemented, except as may have been agreed to in writing by the Purchasers. The Issuer is in compliance in all material respects with the requirements of all applicable laws, rules, regulations, and orders of all Governmental
Authorities. 
 (g) The Issuer is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock,
and no proceeds from the transactions contemplated hereby, directly or indirectly, will be used for a purpose that violates, or would be inconsistent with, Regulations T, U and X promulgated by the Federal Reserve Board from time to time. As used in
this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U. 

(h) All Third-Party Diligence Reports are, as among the parties to this Agreement, deemed to have been obtained by the Issuer pursuant to Rule
15Ga-2 and Rule 17g-10 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and all legal obligations with respect to any such Third-Party Diligence Report have been timely complied with and will continue to be
timely complied with to the satisfaction of the Purchasers. “Third-Party Diligence Report” means any report generated by a third party with respect to due diligence services obtained by the Issuer or the Depositor within the meaning
of Rule 15Ga-2 and Rule 17g-10 of the Exchange Act.

Transaction Documents to which it is a party except as permitted pursuant to the terms thereof. Nothing expressed herein is intended or shall be construed to give any person (other than the persons referred to in the preceding two sentences, in each
case, to the extent provided therein or elsewhere in this Agreement) any legal or equitable right, remedy or claim under or in respect of this Agreement or any other agreement or instrument or against any party hereto or thereto or beneficiary
hereof or thereof.

(b) Each party hereto hereby irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the

irrevocably consents to the service of any and all process in any action or proceeding by the mailing or delivery of copies of such process to it at such party’s address set forth on Schedule 1 hereto. Each party hereto agrees that a
final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. 

(c) EACH PARTY HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

supplement, or waiver of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by the Issuer and the Purchasers. 

Section 14. Severability of Provisions. Any covenant, provision, agreement or term of this Agreement that is prohibited or
is held to be void or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability, without in any way invalidating, affecting or impairing the remaining provisions hereof.
