(i) Accredited Investor. The Owner qualifies as an Accredited Investor and has affirmatively certified as such and indicated on Exhibit A attached hereto the basis for such certification and understands the risks of, and other considerations relating to, the First Merger.

(d) Merger Consideration. The Merger Consideration to be issued hereunder has been duly authorized for issuance and, upon such issuance, will be validly issued, fully paid and nonassessable.

Section 4.03. Representations and Warranties of Merger Sub II. Merger Sub II hereby represents and warrants to the Merging Entity, as of the date of this Agreement and the Closing Date, as follows:

(a) Existence and Power. Merger Sub II has been duly formed and validly exists as a limited liability company under the laws of the State of Delaware.

The execution and delivery of this Agreement by Merger Sub II and the performance of its obligations hereunder have been duly authorized by all requisite limited liability company 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 Merger Sub II, enforceable against Merger Sub II 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 Merger Sub II is a party or such Person is bound or to which any of such Person’s assets are subject, (ii) the Organizational Documents of Merger Sub II, or (iii) any law applicable to Merger Sub II. Other than the filing of the articles of merger and the certificates of merger with respect to the Mergers in accordance with Section 2.02 hereof, 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 Merger Sub II to execute and deliver this Agreement and consummate the transactions contemplated herein.

(c) No Consents. Except for the filing of the articles of merger and the certificates of merger with respect to the Mergers in accordance with Section 2.02 hereof, 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 Merger Sub II 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 Merger Sub Material Adverse Effect.

Section 5.01. Default by the Merging Entity, the Owner or the Splitter Partnership. If the Closing is not consummated because of a default by the Merging Entity, the Owner or the Splitter Partnership under this Agreement, then the Parent and the Merger Subs may either (i) seek specific performance of this Agreement by requiring the Merging Entity to assign the LLC Equity Interests to Upstream Merger Sub and in connection therewith the Owner shall reimburse the Parent and the Merger Subs for the actual out-of-pocket expenses incurred by the Parent or the Merger Subs 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.

Section 6.01. Tax Returns. The Owner shall prepare in accordance with applicable law and timely file any Tax Returns of the Merging Entity with respect to Pre-Closing Tax Periods. The Owner will provide a copy of any such Tax Return to the Parent for its review and comment at least 15 days prior to filing such Tax Return. In the case of any Tax Return for a Pre-Closing Tax Period, the Owners shall pay to the relevant Tax Authority the amount of Tax shown as due on such Tax Return no later than 5 days prior to the time such Tax Return is due.

Section 6.02. Tax Sharing. Any and all Tax sharing agreements or arrangements to which the Merger Entity is a party shall be terminated as of the Closing Date. After the Closing Date, the Merging Entity shall not have any further rights or liabilities thereunder.

Section 6.03. Cooperation on Tax Matters. The Parent and the Owner shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the preparation and filing of any Tax Return and any audit or other proceeding with respect to Taxes. Such cooperation shall include making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Parent and the Owner agree that for each taxable period first ending after the Closing Date and for all prior taxable periods until the later of (i) the expiration of the period of limitations for the assessment of Taxes applicable to the relevant taxable periods to which such Tax Returns and other documents relate, without regard to extensions except to the extent notified by the other party in writing of such extensions for the respective Tax periods (or, if longer, as required by any record retention agreements entered into with any Tax Authority), or (ii) eight years following the due date (without extension) for such Tax Returns, not to destroy or otherwise dispose of (and to cause their respective Affiliates not to destroy or otherwise dispose of) any books or records with respect to Tax matters pertinent to the Merging Entity, unless they shall first offer in writing to surrender such books and records to such other party and such other party does not agree in writing to take possession thereof during the 45 day period after such offer is made.

(a) Subject to Section 6.05, from and after the Closing Date, ES Partnership shall indemnify the Indemnified Parties and hold them harmless from and against all liability for any Taxes imposed on or payable by or with respect to the Merging Entity for any Pre-Closing Tax Periods in connection with or as a result of the Energysource Distribution, and any Losses, liabilities, costs and expenses, including reasonable attorneys’ fees, incurred or arising in connection with or in respect of the assessment, assertion, contest or imposition of a Tax described in this Section 6.04(a) (collectively, a “Special Tax Loss”). ES Partnership’s indemnification obligation pursuant to this Section 6.04 shall be secured by a pledge of its equity interests in Energysource in accordance with the terms and conditions of a pledge agreement to be entered into between the Parent and ES Partnership. Such pledge agreement shall include mutually acceptable provisions providing for the termination of both the pledge and ES Partnership’s indemnification obligations under this Agreement upon the Owner or one of its Affiliates agreeing to indemnify the Indemnified Parties in a manner consistent with this section including providing alternative collateral or other reasonably satisfactory arrangements securing such indemnification obligation.

(b) Not later than 30 days after receipt by the Owner of written notice from the Parent stating that any Special Tax Loss has been incurred by any of the Persons specified in Section 6.04(a) and the amount thereof, ES Partnership shall discharge its indemnification obligation with respect to such Special Tax Loss by paying to the Parent an amount equal to the amount of such Special Tax Loss. The payment by the Parent or any of the other Persons specified in Section 6.04(a) of any Special Tax Loss shall not relieve ES Partnership of its obligation under this Section 6.04.

(c) The Parent agrees to give prompt notice to the Owner, with respect to the Merging Entity, of any Special Tax Loss or the assertion of any claim, or the commencement of any suit, action or proceeding in respect of which indemnity may be sought under this Section 6.04 or Section 7.01 (solely with respect to a breach of a representation or warranty in Section 4.01(h)) (a “Tax Proceeding”) and will give the Owner such information with respect thereto as the Owner may reasonably request. The Owner may assume the defense of any such suit, action or proceeding (including any Tax audit) that relates to a Pre-Closing Tax Period; provided that (x) the Owner shall thereafter consult with the Parent upon the Parent’s reasonable request for such consultation from time to time with respect to such suit, action or proceeding (including any Tax audit) and (y) the Owner shall not, without the Parent’s consent, agree to any settlement with respect to any Tax if such settlement could adversely affect the Tax liability of any Indemnified Party (including, effective upon the Closing, the Merging Entity). If the Owner assumes such defense, (i) the Parent shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Owner and (ii) the Owner shall not assert that the Special Tax Loss, or any portion thereof, with respect to which the Parent seeks indemnification is not within the ambit of this Section 6.04. For avoidance of doubt, unless and until the Owner notifies the Parent in writing of the Owner’s decision to exercise the control and participation rights described in this Section 6.04(d), the Parent shall be entitled to take such actions as it decides are reasonable with respect to such suit, action or proceeding, including paying, compromising or contesting the Tax at issue. Whether or not the Owner chooses to defend or prosecute any claim, all of the parties hereto shall cooperate in the defense or prosecution thereof.

(d) Notwithstanding anything to the contrary in this Agreement, Section 6.04 and not Sections 7.01 and 7.02 shall govern indemnification of the Indemnified Parties in respect of Special Tax Losses and the conduct of Tax Proceedings resulting therefrom.

Section 6.05. Survival. This Article VI shall survive until three calendar years after the Owner’s filing of the Merging Entity’s U.S. federal income tax return for the taxable year that includes the Energysource Distribution.

Section 7.01. Indemnification. Subject to the limitations provided below, from and after the Closing Date, the Owner 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 the Owner or the Merging Entity under this Agreement or (ii) any breach by the Owner of its obligations under this Agreement; provided, however, that the maximum aggregate liability of the Indemnifying Party under this Section 7.01, the Parallel Fund I Merger Agreement and the Contribution Agreement shall not exceed $1,000,000. The Owner’s indemnification obligation pursuant to this Section 7.01 shall be secured by a pledge of the Merger Consideration in accordance with the terms and conditions of a pledge agreement to be entered into between the Parent and the Owner.

Section 7.02. Method of Asserting Claims. All claims for indemnification by any Indemnified Party under this Article VII shall be asserted and resolved as follows:

(a) If an Indemnified Party intends to seek indemnification under this Article VII, it shall promptly notify the Owner in writing of such claim. The failure to provide such notice will not affect any rights hereunder except to the extent the Owner is materially prejudiced thereby.

(b) If such claim involves a claim by a third-party against the Indemnified Party, the Owner 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 the Owner, the settlement or defense thereof (in which case any Loss associated therewith shall be the sole responsibility of the Owner), 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 the Owner’s counsel of (i) the Indemnifying Party and (ii) the Indemnified Party may present such counsel with a conflict of interest, then the Owner 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 the Owner, at any time prior to the delivery of the notice referred to in the first sentence of this Section 7.02(b) by the Owner, 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 VII with respect to such claim and (iii) the Owner 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 the Owner is contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim without the Owner’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 party’s consent. If the Owner 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 the Owner 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 the Owner, the settlement or defense thereof, and the Owner shall cooperate with it in connection therewith. The failure of the Indemnified Party to participate in, conduct or control such defense shall not relieve the Owner of any obligation it may have hereunder. Any defense costs required to be paid by the Owner shall be paid as incurred, promptly against delivery of invoices therefor. Notwithstanding the foregoing, any indemnification chosen by a third-party with respect to any breach of a representation or warranty in Section 4.01(h) shall be governed by Section 6.04(c).

Section 7.03. Survival. This Article VII 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 7.04. Waiver of Claims. Deliverance of the Merger Consideration provided in this Agreement shall serve to waive all claims against the Parent, the Operating Partnership, the Merger Subs and Hannon LLC.

Section 7.05. 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 Merger 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 Merger 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.

Section 8.01. Marketing. Neither the Owner nor the Merging Entity shall 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 Merger Subs and their Affiliates unless this Agreement is terminated in accordance with the terms set forth in Section 2.05.

Section 8.02. 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 8.03. 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 8.04. 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 Mergers shall be the responsibility of and be timely paid 50% by the Owner, on one hand, and 50% by the Parent, on the other hand. The Owner and the Parent shall cooperate in the timely making of all filings, returns, reports and forms as may be required in connection therewith.

Section 8.05. 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 the Owner, Merging Entity or the Splitter Partnership, to the address listed on the Owner, Merging Entity and Splitter Partnership’s signature page to this Agreement.

Section 8.06. 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 8.07. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Maryland without giving effect to any choice or conflict of law provision or rule (whether of the State of Maryland or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Maryland.

Section 8.08. 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 8.09. 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 8.10. 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 8.11. 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 8.12. 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).

Section 8.13. Waiver of Jury Trial. To the fullest extent permitted by 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.

I am an Accredited Investor (as defined in Rule 501 of Regulation D promulgated under the Securities Act) because I hereby certify that (check all appropriate descriptions that apply):

This Amended and Restated Limited Liability Company Agreement (“Agreement”) of Hannon Armstrong Capital LLC (the “LLC”), effective as of [CLOSING DATE] (the “Effective Date”), is entered into by HA Merger Sub III LLC, as the sole member of the LLC (the “Member”).

(b) Additional Members. One or more additional members may be admitted to the LLC with the consent of the Member. Prior to the admission of any such additional members to the LLC, the Member shall amend this Agreement to make such changes as the Member shall determine to reflect the fact that the LLC shall have such additional members. Each additional member shall execute and deliver a supplement or counterpart to this Agreement, as necessary.

(c) Membership Interests; Certificates. To the extent permitted by the Act, notwithstanding any showing that distributions under a charging order upon any economic interest of the LLC will not pay the amount owed to the creditor within a reasonable time, no economic interest in the LLC shall be subject to foreclosure. The LLC will not issue any certificates to evidence ownership of the membership interests.

(a) Authority and Powers of the Member. The Member shall have exclusive and complete authority and discretion to manage the operations and affairs of the LLC and to make all decisions regarding the business of the LLC. Any action taken by the Member shall constitute the act of and serve to bind the LLC.

To the maximum extent permitted under the Act, the Member shall have no duties in its capacity as a member of the LLC, fiduciary or otherwise, to any individual or entity (each such individual or entity and the heirs, personal representatives, successors and assigns of such individual or entity, a “Person”) other than the LLC and its members (including any creditor of the LLC or any such member, or any assignee of any interest in the LLC). No director, officer, member, manager, affiliate or agent of the Member shall have any duties directly to the LLC or any member of the LLC, or to any other Person (including any creditor of the LLC or any Member, or any assignee of any interest in the LLC).

(i) Duty of Care. The Member’s duty of care is limited to refraining from engaging in grossly negligent or reckless conduct, intentional misconduct or knowing violation of law in the discharge of its contractual obligations as expressly set forth in this Agreement. None of the Member or its agents or affiliates shall be expected to devote his, her or its full time to the performance of such duties.

(ii) Duty of Loyalty. The Member’s duty of loyalty is limited to refraining from appropriating the property or assets of the LLC to the benefit of any other Person and without benefit to the LLC. An action of the Member, in its capacity as such, does not violate the Member’s duty of loyalty solely because the Member’s conduct also furthers the Member’s own interests.

(c) Election of Officers; Delegation of Authority. The Member may, from time to time, designate one or more officers with such titles as may be designated by the Member to act in the name of the LLC with such authority as may be delegated to such officers by the Member (each such designated person, an “Officer”). Any such Officer shall act pursuant to such delegated authority until such Officer is removed by the Member. Any action taken by an Officer designated by the Member pursuant to authority delegated to such Officer shall constitute the act of and serve to bind the LLC. Persons dealing with the LLC are entitled to rely conclusively on the power and authority of any officer set forth in this Agreement and any instrument designating such officer and the authority delegated to him, her or it.

(a) Liability of Member. To the fullest extent permitted under the Act, the Member, whether acting as the Member, in its capacity as the manager of the LLC, or in any other capacity, shall not be liable for any debts, obligations or liabilities of the LLC or each other, whether arising in tort, contract or otherwise, solely by reason of being a Member.

(b) Indemnification. To the fullest extent permitted under the Act, the Member, its officers, its directors and any person acting on behalf of the Member (irrespective of the capacity in which it acts) shall be entitled to indemnification and advancement of expenses from the LLC for and against any loss, damage, claim or expense (including attorneys’ fees) whatsoever incurred by the Member relating to or arising out of any act or omission or alleged acts or omissions (whether or not constituting negligence or gross negligence) performed or omitted by the Member on behalf of the LLC; provided, however, that any indemnity under this Section 6(b) shall be provided out of and to the extent of LLC assets only, and neither the Member nor any other person shall have any personal liability on account thereof.

7. Term. The term of the LLC shall be perpetual unless the LLC is dissolved and terminated in accordance with Section 11.

8. Capital Contributions. The Member shall not be required to contribute any additional capital to the LLC, and except as set forth in the Act, no Member shall have any personal liability for any obligations of the LLC. No Member shall be paid interest on its capital contributions.

(a) Tax Status. As long as the LLC has only one member, it is the intention of the LLC and the Member that the LLC be treated as a disregarded entity for federal and all relevant state tax purposes and neither the LLC nor the Member shall take any action or make any election which is inconsistent with such tax treatment. All provisions of this Agreement are to be construed so as to preserve the LLC’s tax status as a disregarded entity.

(b) Income and Deductions. All items of income, gain, loss, deduction and credit of the LLC (including, without limitation, items not subject to federal or state income tax) shall be treated for federal and all relevant state income tax purposes as items of income, gain, loss, deduction and credit of the Member.

10. Distributions. Distributions shall be made to the Member at the times and in the amounts determined by the Member.

(a) The LLC shall dissolve, and its affairs shall be wound up upon the first to occur of the following: (i) the written consent of the Member or (ii) any other event or circumstance giving rise to the dissolution of the LLC under the Act, unless the LLC’s existence is continued pursuant to the Act.

(b) Upon dissolution of the LLC, the LLC shall immediately commence to wind up its affairs and the Member shall promptly liquidate the business of the LLC. During the period of the winding up of the affairs of the LLC, the rights and obligations of the Member under this Agreement shall continue.

(c) In the event of dissolution, the LLC shall conduct only such activities as are necessary to wind up its affairs (including the sale of the assets of the LLC in an orderly manner), and the assets of the LLC shall be applied as follows: (i) first, to creditors, to the extent otherwise permitted by law, in satisfaction of liabilities of the LLC (whether by payment or the making of reasonable provision for payment thereof); and (ii) thereafter, to the Member.

(d) Upon the completion of the winding up of the LLC, the Member shall file Articles of Dissolution in accordance with the Act.

(a) Amendments. Amendments to this Agreement may be made only with the consent of the Member.

(b) Governing Law. This Agreement shall be governed by the laws of the State of Maryland.

(c) Severability. In the event that any provision of this Agreement shall be declared to be invalid, illegal or unenforceable, such provision shall survive to the extent it is not so declared, and the validity, legality and enforceability of the other provisions hereof shall not in any way be affected or impaired thereby, unless such action would substantially impair the benefits to any party of the remaining provisions of this Agreement.

IN WITNESS WHEREOF, the undersigned has executed this Agreement to be effective as of the date first above written.
