Gentlemen:

We understand that the Boards of Directors of Kearny, MHC (“MHC”) and its subsidiaries, Kearny Financial Corp. (“Kearny Financial”) and Kearny Federal Savings Bank (the “Bank”), are considering the adoption of a Plan of Conversion and Reorganization (the “Plan”) pursuant to which the Company will be converted from mutual holding company to stock holding company form, and all of the shares of Kearny Financial currently outstanding (other than shares held by the MHC) will be exchanged for shares of common stock of a successor stock holding company to be formed in connection with the reorganization (the “Holding Company”). Concurrently with the reorganization, the Holding Company also intends to offer and sell certain shares of common stock (the “Shares”) in a public offering. The MHC, Kearny Financial, the Holding Company and the Bank are sometimes collectively referred to herein as the “Company” and their respective Boards of Directors are collectively referred to herein as the “Board.”

Under the terms of the Plan and applicable regulations, the Shares will be offered first to eligible depositors and certain borrower members of the Bank and the Company’s tax-qualified employee stock benefit plans in a subscription offering and, concurrently and subject to the prior rights of eligible depositors and certain borrower members, to certain persons in a community offering, with a preference given in the community offering to residents of the Bank’s community and then to Kearny Financial’s existing stockholders (the subscription offering and the community offering being collectively referred to herein as the “Subscription Offering”). Shares not subscribed for in the Subscription Offering may be offered to the general public through a syndicate of broker-dealers (“Syndicated Offering”) and/or in a firm commitment

public offering (the “Firm Commitment Offering” and together with the Subscription Offering and Syndicated Offering, the “Offering”). Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”) is pleased to assist the Company with the Offering and this letter is to confirm the terms and conditions of our engagement.

Services

Sandler O’Neill will work with the Company and its management, counsel, accountants and other advisors in preparing for and completing the Offering and anticipate that our services will include the following:

Sandler O’Neill will act as exclusive marketing agent for the Company in the Subscription Offering and will serve as sole book-running manager of the Syndicated Offering and/or Firm Commitment Offering. The Company has advised Sandler O’Neill that it expects to invite certain other broker-dealers to serve as co-managers of any Firm Commitment Offering (collectively, the “Co-managers”). It is understood that neither Sandler O’Neill nor any Co-manager shall be obligated to take or purchase any Shares in the Offering other than as may be expressly agreed to by such firms and the Company in an underwriting agreement for a Firm Commitment Offering.

Fees

If the Offering is consummated, the Company agrees to pay Sandler O’Neill for its marketing agent services a fee of one percent (1.00%) of the aggregate Actual Purchase Price of all Shares sold in the Subscription Offering, excluding Shares purchased by or on behalf of (i) any employee benefit plan or trust of the Company established for the benefit of its directors, officers and employees, (ii) any director, officer or employee of the Company or members of their immediate families (whether directly or through a personal trust), as to which no fee shall be payable, and (iii) shares issued to the foundation established in connection with the Plan and the Offering.

With respect to any Shares sold in the Syndicated Offering and/or Firm Commitment Offering, the Company agrees to pay to Sandler O’Neill and any Co-managers an aggregate fee of 5.0% of the aggregate Actual Purchase Price of all Shares sold in the Syndicated Offering and/or Firm Commitment Offering, of which not less than 65% shall be paid to Sandler O’Neill with the remainder to be paid to the Co-managers in such proportion as the Company may determine.

For purposes of this letter, the term “Actual Purchase Price” shall mean the price at which the shares of the Company’s common stock are sold in the Offering. It is understood and agreed that no fee shall be paid with respect to any shares issued to minority stockholders in exchange for their current shares as a result of the reorganization. All fees payable hereunder shall be payable in immediately available funds by wire transfer at the time of the closing of the Offering.

Expenses

In addition to any fees that may be payable hereunder and the expenses to be borne by the Company pursuant to the following paragraph, the Company agrees to reimburse Sandler O’Neill, upon request made from time to time, for its reasonable legal fees and expenses incurred in connection with the Offering, regardless of whether the Offering is consummated, up to a maximum aggregate amount of $250,000; provided, however, that such expenses shall be documented to the reasonable satisfaction of the Company. Sandler O’Neill and any Co-managers shall bear all of their other out-of-pocket expenses incurred in connection with the Offering. The provisions of this paragraph are not intended to apply to or in any way impair the indemnification provisions of this letter.

As is customary, the Company will bear all other expenses incurred in connection with the Offering, including, without limitation, (a) the cost of obtaining all securities and bank

regulatory approvals, including any required FINRA filing fees; (b) the cost of printing and distributing the offering materials; (c) the costs of blue sky qualification (including fees and expenses of blue sky counsel) of the Shares in the various states; (d) listing fees; and (e) all fees and disbursements of the Company’s counsel, accountants and other advisors. In the event Sandler O’Neill incurs any such fees and expenses on behalf of the Company, the Company will reimburse Sandler O’Neill for such fees and expenses whether or not the Offering is consummated.

Due Diligence Review

Sandler O’Neill’s obligation to perform the services contemplated by this letter shall be subject to the satisfactory completion of such investigation and inquiries relating to the Company and its directors, officers, agents and employees as Sandler O’Neill and its counsel in their sole discretion may deem appropriate under the circumstances. In this regard, the Company agrees that, at its expense, it will make available to Sandler O’Neill all information reasonably requested, and will allow Sandler O’Neill the opportunity to discuss with the Company’s management the financial condition, business and operations of the Company, and will afford a similar opportunity to any Co-manager. The Company acknowledges that Sandler O’Neill and any Co-manager will rely upon the accuracy and completeness of all information received from the Company and its directors, officers, employees, agents, independent accountants and counsel.

Blue Sky Matters

Sandler O’Neill and the Company agree that the Company’s counsel shall serve as counsel with respect to blue sky matters in connection with the Offering. The Company shall cause such counsel to prepare a Blue Sky Memorandum related to the Subscription Offering and the Firm Commitment Offering, including Sandler O’Neill’s and, as applicable, any Co-managers’ participation therein, and shall furnish Sandler O’Neill a copy thereof addressed to Sandler O’Neill and, as applicable, the Co-managers, or upon which such counsel shall state Sandler O’Neill and, as applicable, the Co-managers, may rely.

Confidentiality

Except as contemplated in connection with the performance of its services under this agreement, as authorized by the Company or as required by law, regulation or legal process, Sandler O’Neill agrees that it will treat as confidential all material, non-public information relating to the Company obtained in connection with its engagement hereunder (the “Confidential Information”); provided, however, that Sandler O’Neill may disclose such Confidential Information to its agents, consultants and advisors who are assisting or advising

Sandler O’Neill in performing its services hereunder and to any other Co-manager, provided they have agreed to be bound by the terms and conditions of this paragraph. As used in this paragraph, the term “Confidential Information” shall not include information which (a) is or becomes generally available to the public other than as a result of a disclosure by Sandler O’Neill, (b) was available to Sandler O’Neill on a non-confidential basis prior to its disclosure to Sandler O’Neill by the Company, or (c) becomes available to Sandler O’Neill on a non-confidential basis from a person other than the Company who is not otherwise known to Sandler O’Neill, upon due inquiry, to be bound not to disclose such information pursuant to a contractual, legal or fiduciary obligation.

The Company agrees to indemnify and hold Sandler O’Neill, its affiliates and their respective partners, directors, officers, employees, agents and controlling persons within the meaning of Section 15 of the Securities Act of 1933 or Section 20 of the Securities Exchange Act of 1934 (each such firm and person being an “Indemnified Party”) harmless from and against any and all losses, claims, damages and liabilities, joint or several, to which such Indemnified Party may become subject under applicable federal or state law, or otherwise, related to or arising out of the Offering or the engagement of Sandler O’Neill pursuant to, or the performance by Sandler O’Neill of the services contemplated by, this letter, and will reimburse any Indemnified Party for all expenses (including reasonable legal fees and expenses) as they are incurred, including expenses incurred in connection with the investigation of, preparation for or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party; provided, however, that the Company shall only be obligated to pay for one separate counsel (in addition to any required local counsel) in any one action or proceeding or group of related actions or proceedings for all Indemnified Parties collectively, and provided further that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense (a) arises out of or is based upon any untrue statement of a material fact or the omission of a material fact required to be stated therein or necessary to make not misleading any statements contained in any final prospectus, or any amendment or supplement thereto, made in reliance on and in conformity with written information furnished to the Company by Sandler O’Neill expressly for use therein, or (b) is primarily attributable to the gross negligence, willful misconduct or bad faith of Sandler O’Neill. Notwithstanding the above, Sandler O’Neill and the Company hereby agree that in no event will any payments be made by the Company pursuant to this section that are prohibited by Section 18(k) of the Federal Deposit Insurance Act and its implementing regulations at 12 CFR Part 359. If the foregoing indemnification is unavailable for any reason other than for the reasons stated in subparagraph (a) or (b) above, the Company agrees to contribute to such losses, claims, damages, liabilities and expenses in the proportion that its financial interest in the
