NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

1.1 Subject to the requisite approval of the Target Fund’s shareholders and the other terms and conditions herein set forth, and on the basis of the representations and warranties contained herein, (i) the Henderson Trust shall transfer all of the Assets (as defined below) of the Target Fund, as set forth in paragraph 1.2, to the Acquiring Fund, (ii) the Janus Trust shall cause the Acquiring Fund to deliver to the Henderson Trust full and fractional (rounded to the fourth decimal place) Class A, C, I and N Acquiring Fund Shares having an aggregate net asset value equal to the value of the aggregate net assets of the same class of shares of the Target Fund (except that Class N Acquiring Fund Shares shall be delivered to the Target Fund having an aggregate net asset value equal to the value of the aggregate net assets of Class R6 Shares of the Target Fund), as of the close of regular session trading on the New York Stock Exchange (the “Valuation Time”) on the Closing Date, as set forth in paragraph 2.1 (the “Closing Date”) and (iii) the Janus Trust shall cause the Acquiring Fund to assume all Liabilities (as defined below) of the Target Fund, as set forth in paragraph 1.2. Such transactions shall take place at the closing provided for in paragraph 2.1 (the “Closing”). The aggregate number of shares of the Acquiring Fund to be issued and delivered to the Target Fund shall be determined as set forth in Section 2.7.

1.2 The assets of the Target Fund to be acquired by the Acquiring Fund shall consist of all assets and property, including, without limitation, all cash, securities, commodities, interest in futures and other financial instruments, claims (whether absolute or contingent, known or unknown, accrued or unaccrued and including, without limitation, any interest in pending or future legal claims in connection with past or present portfolio holdings, whether in the form of class action claims, opt-out or other direct litigation claims, or regulator or government-established investor recovery fund claims, and any and all resulting recoveries), dividends, interest or other receivables that are owned by the Target Fund and any deferred or prepaid expenses shown as an asset on the books of the Target Fund on the Closing Date (“collectively, the “Assets”).

1.3 To the extent consistent with the Target Fund’s investment objective and policies, the Target Fund will use its reasonable best efforts to discharge all of its known liabilities and obligations prior to the Valuation Time. The Acquiring Fund will assume all of the liabilities, expenses, costs, charges, debts, obligations, duties and reserves of the Target Fund of any kind, whether absolute, accrued, contingent, known or unknown, or otherwise in existence on the Closing Date; provided, however, the Acquiring Fund shall not assume (i) any obligation arising from the termination of the agreements set forth in Schedule 4.2(iv) or (ii) any obligations of the Target Fund under this Agreement, including indemnification obligations. (collectively the “Liabilities”).

1.4 The Target Fund will distribute in liquidation of the Target Fund pro rata to its shareholders of record of the applicable classes, determined as of immediately after the close of business on the Closing Date (the “Current Shareholders”), the Class A, C, I and N Acquiring Fund Shares received by the Henderson Trust pursuant to paragraph 1.1. Such distribution and liquidation will be accomplished by the transfer of the Class A, C, I and N Acquiring Fund Shares then credited to the accounts of the Target Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of the Current Shareholders and representing the respective pro rata number of the corresponding class of Acquiring Fund Shares due to such shareholders (provided that holders of Class R6 Shares of the Target Fund shall be credited Class N Acquiring Fund Shares). All issued and outstanding shares of the Target Fund will simultaneously be canceled on the books of the Target Fund. The Acquiring Fund shall not issue certificates representing the Class A, C, I and N (and Class D when issued) Acquiring Fund Shares in connection with such exchange. Ownership of Class (and Class D when issued) Acquiring Fund Shares will be shown on the books of the Janus Trust’s transfer agent. As soon as reasonably practicable after the Closing, the Henderson Trust shall take all steps necessary to effect a complete liquidation of the Target Fund in accordance with its governing instruments and applicable law, and the Target Fund shall not conduct any business after the Closing Date, except as contemplated herein.

1.5 To the extent consistent with the Target Fund’s investment objective and policies, the Target Fund agrees to use reasonable best efforts to dispose of certain assets prior to the Closing as requested by the Acquiring Fund to the extent necessary to ensure that the combined portfolio following the

Closing meets the investment objective, policies and restrictions of the Acquiring Fund. Notwithstanding the foregoing, nothing herein shall permit or require the Target Fund to dispose of any investments or securities if, in the reasonable judgment of the Board of the Henderson Trust or the investment adviser to the Target Fund, such disposition would adversely affect the status of the Reorganization as a “reorganization” as such term is used in Section 368(a) of the Code or would adversely affect the Target Fund’s status as a “regulated investment company” under the Code, or would not be in the best interest of the Target Fund’s shareholders.

1.6 Any transfer taxes payable upon issuance of the Acquiring Fund Shares in a name other than the registered holder of the Target Fund Shares on the books and records of the Target Fund as of that time shall, as a condition of such issuance and transfer, be paid by the person to whom such Acquiring Fund Shares are to be issued and transferred.

2.3 The Henderson Trust shall cause Boston Financial Data Services, transfer agent of the Target Fund, to deliver at the Closing a certificate of an authorized officer stating that its records contain the names and addresses of the Current Shareholders and the number, class, dividend reinvestment election, tax withholding status and percentage ownership of outstanding shares of the Target Fund owned by each such shareholder immediately prior to the Closing. The Janus Trust shall issue and deliver or cause Janus Services LLC, the transfer agent to the Acquiring Fund, to issue and deliver a confirmation evidencing the Class A, C, I and N Acquiring Fund Shares to be credited on the Closing Date to the Secretary of the Henderson Trust or provide evidence satisfactory to the Henderson Trust that such Class A, C, I and N Acquiring Fund Shares have been credited to the account of the Current Shareholders on the books of the Acquiring Fund.

2.6 The net asset value per share of the Acquiring Fund Shares to be delivered to the Target Fund, the value of the Assets of the Target Fund transferred hereunder and the value of the Liabilities of the Target Fund to be assumed hereunder shall, in each case, be determined as of the Valuation Time. Such valuations and determinations shall be made by the Acquiring Fund, in cooperation with the Target Fund, in accordance with the Acquiring Fund’s valuation procedures established by the Board of Trustees of the Janus Trust, which shall be provided to the Target Fund prior to the Valuation Time, and shall be confirmed in writing to the Target Fund. All computations of value shall be subject to review by the Target Fund and, if requested by either the Henderson Trust or the Janus Trust, by the independent registered public accountant of the requesting party.

2.7 The number of Acquiring Fund Shares of each class to be issued (including fractional shares to the third decimal place) shall be determined by dividing the value of the (i) Assets with respect to the corresponding class of the Target Fund, net of the Liabilities of the Target Fund with respect to the corresponding class of the Target Fund (each calculated as of the Valuation Time in accordance with Section 2.6), by (ii) the net asset value per share of the applicable class of the Acquiring Fund as of the Valuation Time.

2.8 The net asset value per share of each class of the Acquiring Fund shares issued in connection with the Reorganization shall be the net asset value per share of the corresponding class of the Target Fund as of the Valuation Time, determined as set forth in Section 2.6 above, provided that, if more than one class of shares of the Target Fund is being exchanged for a single class of shares of the Acquiring Fund, then the net asset value per share of such class of shares of the Acquiring Fund issued in connection with the Reorganization shall be the net asset value per share of the corresponding class of the Target Fund having attributes most consistent with the Acquiring Fund share class, as determined by the Acquiring Fund, or the net asset value of such other class of shares of the Acquiring Fund as the parties may mutually agree .

2.9 The Target Fund shall be the accounting and performance survivor in the Reorganization, with the result that the Acquiring Fund, as the corporate survivor in the Reorganization, shall adopt the accounting and performance history of the Target Fund.

4.1 Except to the extent waived in writing by the Henderson Trust, the obligations of the Henderson Trust on behalf of the Target Fund to effectuate the Reorganization shall be subject to the satisfaction of the following conditions:

(i) Class A, C, I, N and D Acquiring Fund Shares shall have been duly qualified for offering to the public in all states in which such qualification is required for consummation of the transactions contemplated hereunder;

(ii) All representations and warranties of the Janus Trust on behalf of the Acquiring Fund contained in this Agreement shall be true and correct in all material respects as of the date hereof and, except as they may be affected by the transactions contemplated by this Agreement, as of the Closing, with the same force and effect as if then made;

(iii) The Henderson Trust on behalf of the Target Fund shall have received a certificate of an officer of the Janus Trust on behalf of the Acquiring Fund in form and substance reasonably satisfactory to the Henderson Trust and dated as of the Closing Date, certifying that the representations and warranties of or with respect to the Janus Trust and the Acquiring Fund made in this Agreement are true and correct at and as of the Closing Date, except as they may be affected by the transactions contemplated by this Agreement, and as to such other matters as the Henderson Trust shall reasonably request;

(iv) The Janus Trust and the Acquiring Fund shall have performed all obligations required to be performed by the Janus Trust or the Acquiring Fund under this Agreement at or prior to the Closing Date;

(v) The Janus Trust, on behalf of the Acquiring Fund, shall have executed and delivered to the Henderson Trust, on behalf of the Target Fund, an Assumption of Liabilities dated as of the Closing Date pursuant to which the Acquiring Fund will assume all of the liabilities of the Target Fund existing at the Closing Date in connection with the transactions contemplated by this Agreement; and

(vi) The Henderson Trust shall have received the opinion or letter of Skadden, Arps, Slate, Meagher & Flom LLP (“Skadden”), dated as of the Closing Date, addressed to the Henderson Trust and the Target Fund substantially in the form and to the effect that:

(1) the Janus Trust is validly existing in good standing under the laws of the Commonwealth of Massachusetts;

(2) the Janus Trust has the power and authority to execute and deliver the Agreement and to consummate the transactions contemplated thereby

(3) the Agreement has been duly authorized, executed and delivered by the Janus Trust;

(4) the Agreement constitutes the valid and binding obligation of the Janus Trust, enforceable against the Janus Trust in accordance with its terms under the laws of the Commonwealth of Massachusetts, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(5) neither the execution and delivery by the Janus Trust of the Agreement nor the performance by the Janus Trust of its obligations under the Agreement: (a) conflicts with the governing documents of the Janus Trust; (b) constitutes a violation of, or a default under, any material contract, agreement, instrument or other document pertaining to, or material to the business or financial condition of, the Acquiring Fund; (c) contravenes any material judgement, order or decree of courts of other governmental authorities or arbitrators that are material to the business or financial condition of the Acquiring Fund; or (d) violates the 1940 Act or any law, rule or regulation of the Commonwealth of Massachusetts;

(6) neither the execution and delivery by the Janus Trust of the Agreement nor the performance by the Janus Trust of its obligations under the Agreement requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under the 1940 Act or any law, rule or regulation of the Commonwealth of Massachusetts, except for those consents, approvals, licenses and authorizations already obtained and those filings, recordings and registrations already made; and

(7) when the Acquiring Fund Shares have been duly issued and delivered to the Target Fund for distribution to the shareholders of the Target Fund in exchange for the Acquiring Fund’s acquisition of all of the Target Fund’s assets and assumption of all of the Target Fund’s liabilities, in accordance with the terms of the Agreement, and entered into the share record books of the Acquiring Fund, the issuance of the Acquiring Fund Shares will have been duly authorized by all requisite action on the part of the Janus Trust and the Acquiring Fund Shares will be validly issued, fully paid and, subject to the following, non-assessable. Pursuant to certain decisions of the Supreme Judicial Court of The Commonwealth of Massachusetts, shareholders of a Massachusetts business trust may, in certain circumstances, be held personally liable as partners for the obligations of a Massachusetts business trust. Even if the Janus Trust were held to be a partnership, however, the possibility of the holders of Acquiring Fund Shares incurring personal liability for financial losses of the Acquiring Fund appears remote because the Janus Declaration of Trust disclaims shareholder liability for acts or obligations of the Acquiring Fund and requires that notice of this disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Acquiring Fund or the Trustees. The Janus Declaration of Trust also provides for indemnification from the assets of the Acquiring Fund for all losses and expenses of any Acquiring Fund shareholder held liable for the obligations of the Acquiring Fund;

(8) the Janus Trust is registered with the Commission pursuant to Section 8 of the 1940 Act as an open-end management investment company; and

(ii) The Janus Trust on behalf of the Acquiring Fund shall have received a certificate of an officer of the Henderson Trust on behalf of the Target Fund in form and substance reasonably satisfactory to the Janus Trust and dated as of the Closing Date, certifying that the representations and warranties of or with respect to the Henderson Trust and the Target Fund made in this Agreement are true and correct at and as of the Closing Date, except as they may be affected by the transactions contemplated by this Agreement, and as to such other matters as the Janus Trust shall reasonably request;

(iii) The Henderson Trust shall have performed all obligations required to be performed by it under this Agreement at or prior to the Closing Date;

(iv) The Target Fund’s agreements with each of the parties set forth on Schedule 4.2(iv) hereto shall have been terminated as of the Closing with respect to the Target Fund, and each party to this Agreement shall have received evidence of such termination and assurance that no claims for damages (liquidated or otherwise) will arise as a result of such termination.

(v) The Janus Trust shall have received the opinion of Vedder Price P.C., dated as of the Closing Date, addressed to the Janus Trust and the Acquiring Fund substantially in the form and to the effect that:

(1) the Henderson Trust is validly existing in good standing under the laws of the State of Delaware;

(2) the Henderson Trust has the power and authority to execute and deliver the Agreement and to consummate the transactions contemplated thereby

(3) the Agreement has been duly authorized, executed and delivered by the Henderson Trust;

(4) the Agreement constitutes the valid and binding obligation of the Henderson Trust, enforceable against the Henderson Trust in accordance with its terms under the laws of the State of Delaware, subject, as to enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether considered enforcement is sought in equity or at law);

(6) neither the execution and delivery by the Henderson Trust of the Agreement nor the performance by the Henderson Trust of its obligations under the Agreement requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under the 1940 Act or any law, rule or regulation of the State of Delaware, except for those consents, approvals, licenses and authorizations already obtained and those filings, recordings and registrations already made; and

(7) the Henderson Trust is registered with the Commission pursuant to Section 8 of the 1940 Act as an open-end management investment company.

4.3 Except to the extent waived in writing by both the Henderson Trust and the Janus Trust, the obligations of the Henderson Trust, on behalf of the Target Fund, and the Janus Trust, on behalf of the Acquiring Fund, to consummate the Reorganization shall be subject to the satisfaction of the following conditions:

(iii) This Agreement has been approved by the affirmative vote of Target Fund Shareholders representing a “majority of the outstanding voting securities” (as defined in the 1940 Act) of the Target Fund; notwithstanding anything herein to the contrary, neither the Henderson Trust nor the Janus Trust may waive the condition set forth in this paragraph 4.3(iii);

(iv) The Target Fund and the Acquiring Fund shall have agreed on the number of full and fractional shares of each class of shares of the Acquiring Fund to be issued in connection with the Reorganization after such number has been calculated in accordance with this Agreement;

(v) No judgment, order, decree, statute, law, ordinance, rule or regulation, entered, enacted, promulgated, enforced or issued by any court or other governmental entity of competent jurisdiction or other legal restraint or prohibition, whether preliminary, temporary or permanent, shall be in effect that prevents, makes illegal or prohibits the consummation of the Reorganization;

(vi) As of the Closing Date, there shall be no pending litigation brought by any person against the Henderson Trust or the Target Fund or, the Janus Trust or the Acquiring Fund, or any of the investment advisers, directors or officers of the foregoing, as applicable, arising out of, or seeking to prevent completion of the transactions contemplated by, this Agreement. Furthermore, no action, suit or other proceeding shall be pending before any court or governmental agency in which it is sought to restrain or prohibit, or obtain damages or other relief in connection with, this Agreement or the transactions contemplated herein.

(vii) On the Closing Date, the Commission shall not have issued an unfavorable report under Section 25(b) of the 1940 Act, nor instituted any proceeding seeking to enjoin the consummation of the transactions contemplated by this Agreement under Section 25(c) of the 1940 Act;

(ix) The Acquiring Fund and Target Fund shall have received an opinion in form reasonably satisfactory to each such party, dated as of the Closing Date, of Skadden, Arps, Slate, Meager and Flom LLP, substantially to the effect that for U.S. federal income tax purposes the Reorganization will constitute a “reorganization” within the meaning of Section 368(a) of the Code. Notwithstanding anything herein to the contrary, neither the Henderson Trust nor the Janus Trust may waive the condition set forth in this paragraph 4.3(ix).

(x) The Target Fund shall have declared and paid a dividend prior to the Closing Time, which, together with all previous dividends, will have the effect of distributing to its shareholders all of the Target Fund’s investment company taxable income (within the meaning of Section 852(b)(2) of the Code, computed without regard to any deduction for dividends paid), if any, plus any excess of its interest income excludible from gross income under Section 103(a) of the Code over its deductions disallowed under Sections 265 and 171(a)(2) of the Code for all periods up to and including the Closing Date, and all of the Target Fund’s net capital gain (as defined in Section 1222(11) of the Code), if any, for the avoidance of doubt after reduction for any usable capital loss carryforwards, recognized in all periods up to and including the Closing Date.

(“Janus”), with Janus surviving the merger as a direct wholly-owned subsidiary of Henderson, pursuant to the Agreement and Plan of Merger, dated as of October 3, 2016, among Janus, Henderson and Merger Sub (the “Janus Henderson Group Merger”), shall have been consummated.

5.1 JCM agrees that it will bear all costs and expenses of the Janus Trust and the Acquiring Fund incurred in connection with the Reorganization and transactions contemplated thereby and HGINA agrees that it will bear all costs and expenses of the Henderson Trust and the Target Fund incurred in connection with the Reorganization and transactions contemplated thereby. The costs of the Reorganizations shall include, but not be limited to, organizing the Acquiring Fund, preparation, printing and distribution of the N-14 Registration Statement and the Proxy Statement/Prospectus, legal fees, accounting fees, proxy solicitation costs, and expenses of holding shareholders’ meetings.

5.2 Each of the Henderson Trust and the Janus Trust represents that there is no person who has dealt with it who by reason of such dealing is entitled to any broker’s or finders’ or other similar fee or commission arising out of the transactions contemplated by this Agreement.

6.1 During the period from the date of this Agreement and continuing until the Closing Date, the Janus Trust, on behalf of the Acquiring Fund, and the Henderson Trust, on behalf of the Target Fund, agree that:

At or prior to the Closing Date, the Acquiring Fund and the Target Fund will take such action, or cause such action to be taken, as is reasonably necessary to enable Skadden to render the tax opinions required as a condition to the Closing of this Agreement (including, without limitation, each party’s execution of representations reasonably requested by and addressed to Skadden).

(vi) At or prior the Closing Date, the Henderson Trust will provide the Janus Trust with (a) a statement of the respective tax basis and holding period of all the transferred Assets, (b) a copy (which may be in electronic form) of the shareholder ledger accounts including, without limitation, the name, address and taxpayer identification number of each shareholder of record, the number of shares of beneficial interest held by each shareholder, the dividend reinvestment elections applicable to each shareholder, and the backup withholding and nonresident alien withholding certifications, notices or records on file with the Target Fund with respect to each shareholder, for all of the shareholders of record of the Target Fund as of the Closing Date, who are to become holders of the Acquiring Fund as a result of the Reorganization, certified by the transfer agent of the Target Fund or an officer of the Henderson Trust on behalf of the Target Fund to the best of their knowledge and belief, (c) if requested by the Acquiring Fund, all FIN 48 work papers and supporting statements pertaining to the Target Fund, and (d) the tax books and records of the Target Fund for purposes of preparing any returns required by law to be filed for tax periods ending after the Closing Date; and

(vii) The Target Fund will assist the Acquiring Fund in obtaining such information as the Acquiring Fund reasonably requests concerning the beneficial ownership of the Target Fund’s shares;

6.4 As soon as practicable after the Closing of the Reorganization, Class A, C, I and N Acquiring Fund Shares received by shareholders who were direct shareholders of the Target Fund, will be automatically exchanged for Class D Shares of the Acquiring Fund having an equal aggregate net asset value to the shares so exchanged.

The Henderson Trust, on behalf of the Target Fund, and the Janus Trust, on behalf of the Acquiring Fund, agree that this Agreement constitutes the entire agreement between the parties.

8.1 This Agreement and the transactions contemplated hereby may be terminated and abandoned by the mutual agreement of the Henderson Trust and the Janus Trust.

8.2 Either the Henderson Trust or the Janus Trust may at its option terminate this Agreement at or prior to the Closing Date because:

(i) of a material breach by the other party of any representation, warranty or agreement contained herein to be performed at or prior the Closing Date;

(ii) a condition herein expressed to be precedent to the obligations of the terminating party has not been met and it reasonably appears that it will not or cannot be met prior to the Closing Date;

(iii) there shall be a final, non-appealable order of a federal or state court in effect preventing consummation of the transactions contemplated hereby; or there shall be any final action taken, or any statute, rule, regulation or order enacted, promulgated or issued or deemed applicable to the transactions contemplated hereby by any governmental entity which would make consummation of the transactions contemplated hereby illegal; or

(iv) the closing has not occurred on or prior to _____, 2017 (provided that the right to terminate this Agreement pursuant to this paragraph 8.2(iii) shall not be available to any party whose failure to fulfill any of its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such date).

8.3 In the event that the Board of Trustees of the Henderson Trust or the Board of Trustees of the Janus Trust reasonably determines, after consultation with outside counsel, that the failure to terminate this Agreement would constitute a breach of the fiduciary duties of such Board of Trustees (such fiduciary duty to be interpreted in accordance with the laws of the state in which such trust is organized), such party may terminate this Agreement with the written consent of the other party, which consent shall not be unreasonably withheld. The party seeking termination pursuant to this Section 8.3 shall provide written notice to the other party of the determination by the Board of Trustees of the party seeking termination and the facts and circumstances that form the basis for such determination.

This Agreement may be amended, modified or supplemented in such manner as may be mutually agreed upon in writing by the parties; provided, however, that at any time after the approval of this Agreement by Target Fund Shareholders, no amendment or modification shall be made which by law requires further approval by such shareholders without such further approval.

Any notice, report, statement or demand required or permitted by any provisions of this Agreement shall be in writing and shall be given by facsimile, overnight courier, personal delivery or certified mail addressed to:

Copies of all books and records of the Target Fund shall be delivered by the Henderson Trust to the Janus Trust at the Closing Date. Prior to the Closing and for a reasonable time thereafter, the Henderson Trust on behalf of the Target Fund and the Janus Trust on behalf of the Acquiring Fund will provide each other and their respective representatives with such cooperation, assistance and information as is reasonably necessary (i) for the filing of any tax return, for the preparation for any audit, and for the prosecution or defense of any claim, suit or proceeding relating to any proposed adjustment, or (ii) for any financial accounting purpose. Until the applicable period for assessment under applicable law (giving effect to any and all extensions or waivers) has expired, each such party or their respective agents will retain all returns, schedules and work papers and all material records or other documents relating to tax matters and financial reporting of tax positions of the Target Fund and the Acquiring Fund for its taxable period first ending after the Closing Date and for all prior taxable periods for which the statute of limitation had not run at the Closing Date, provided that the Henderson Trust shall not be required to maintain any such documents that it has delivered to the Janus Trust.

Each series of the Henderson Trust (i) has entered into (or will enter into) an agreement and plan of reorganization pursuant to which the assets of such series would be transferred to, and the liabilities of such series would be assumed by, a series of the Janus Trust, (ii) will be reorganized into an entity, which after giving effect to such reorganization, is not required to register as an investment company or (iii) will adopt a plan of liquidation or engage in such other transaction or transactions which results in the liquidation of such series. Upon the completion of all such transactions, the Henderson Trust will be

terminated and dissolved in accordance with the Henderson Declaration of Trust, the laws of the State of Delaware and any other applicable law and shall not conduct any business except in connection with its dissolution and termination.

13.1 Each party (an “Indemnitor”) shall indemnify and hold the other and its officers, directors, trustees, agents and persons controlled by or controlling any of them (each an “Indemnified Party”) harmless from and against any and all losses, damages, liabilities, claims, demands, judgments, settlements, deficiencies, taxes, assessments, charges, costs and expenses of any nature whatsoever (including reasonable attorneys’ fees and reasonable costs of investigation) including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by such Indemnified Party in connection with the defense or disposition of any claim, action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which such Indemnified Party may be or may have been involved as a party or otherwise or with which such Indemnified Party may be or may have been threatened (collectively, the “Losses”) arising out of or related to any claim of a breach of any representation, warranty or covenant made herein by the Indemnitor; provided, however, that no Indemnified Party shall be indemnified hereunder against any Losses arising directly from such Indemnified Party’s (i) willful misfeasance, (ii) bad faith, (iii) gross negligence or (iv) reckless disregard of the duties involved in the conduct of such Indemnified Party’s position.

13.2 The Indemnified Party shall use its best efforts to minimize any liabilities, damages, deficiencies, claims, judgments, assessments, costs and expenses in respect of which indemnity may be sought hereunder. The Indemnified Party shall give written notice to Indemnitor within the earlier of ten (10) days of receipt of written notice to the Indemnified Party or thirty (30) days from discovery by the Indemnified Party of any matters which may give rise to a claim for indemnification or reimbursement under this Agreement. The failure to give such notice shall not affect the right of the Indemnified Party to indemnity hereunder unless such failure has materially and adversely affected the rights of the Indemnitor. At any time after ten (10) days from the giving of such notice, the Indemnified Party may, at its option, resist, settle or otherwise compromise, or pay such claim unless it shall have received notice from the Indemnitor that the Indemnitor intends, at the Indemnitor’s sole cost and expense, to assume the defense of any such matter, in which case the Indemnified Party shall have the right, at no cost or expense to the Indemnitor, to participate in such defense. If the Indemnitor does not assume the defense of such matter, and in any event until the Indemnitor states in writing that it will assume the defense, the Indemnitor shall pay all costs of the Indemnified Party arising out of the defense until the defense is assumed; provided, however, that the Indemnified Party shall consult with the Indemnitor and obtain indemnitor’s prior written consent to any payment or settlement of any such claim. The Indemnitor shall keep the Indemnified Party fully apprised at all times as to the status of the defense. If the Indemnitor does not assume the defense, the Indemnified Party shall keep the Indemnitor apprised at all times as to the status of the defense. Following indemnification as provided for hereunder, the Indemnitor shall be subrogated to all rights of the Indemnified Party with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made.
