The Shares of the Portfolio, and the Classes thereof, shall have the additional relative rights and preferences, shall be subject to the liabilities, shall have the other characteristics, and shall be subject to the powers of the Trustees, all as set forth in Article 6 of the Declaration of Trust, as from time to time in effect. Without limitation of the foregoing sentence, each Share of such Series representing the beneficial interest of the Portfolio shall be redeemable, shall be entitled to one vote, or a ratable fraction of one vote in respect of a fractional Share, as to matters on which Shares of such Series shall be entitled to vote, and shall represent a share of the beneficial interest of the Portfolio, all as provided in the Declaration of Trust.

(2)    Amendment, etc. Subject to the provisions and limitations of Section 9.3 of the Declaration of Trust and applicable law, this Amended Certificate may be amended by an instrument signed in writing by a Majority of the Trustees (or by an officer of the Trust pursuant to the vote of a Majority of the Trustees), provided, that, if any such amendment adversely affects the rights of the Shareholders of the Portfolio, such amendment shall be adopted by an instrument signed in writing by a Majority of the Trustees (or by an officer of the Trust pursuant to the vote of a Majority of the Trustees) when authorized to do so by the vote in accordance with Section 7.1 of the Declaration of Trust of the holders of a majority of all the Shares of the Portfolio outstanding and entitled to vote.

(3)    Incorporation of Defined Terms. All capitalized terms which are not defined herein shall have the same meanings as are assigned to those terms in the Declaration of Trust.

The Trustees further direct that, upon the execution of this Amended Certificate, the Trust take all necessary action to file a copy of this Amended Certificate with the Secretary of

the Commonwealth of Massachusetts and at any other place required by law or by the Declaration of Trust.

Dear Sirs:

Fred Alger Management, LLC (“FAM”) hereby agrees to waive fees owed to it by, or to reimburse expenses of, the share classes of each series (each, a “Fund”) of The Alger Funds (the “Trust”) listed on Schedule A for the expense cap period indicated. FAM will waive its fees and/or reimburse expenses to the extent total operating expenses exceed the rate of average daily net assets indicated on Schedule A. This expense limitation does not include acquired fund fees and expenses, dividend expense on short sales, borrowing costs, interest, taxes, brokerage and extraordinary expenses.

FAM understands and intends that the Trust will rely on this agreement in preparing and filing its registration statements on Form N-1A and in accruing each Fund’s expenses for purposes of calculating net asset value and for other purposes.

This Agreement may only be amended or terminated prior to its expiration date by agreement between FAM and the Trust’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement between FAM and the Trust, on behalf of each Fund. FAM may, during the two-year period of this contract, recoup any fees waived or expenses reimbursed pursuant to this contract to the extent that such recoupment would not cause the expense ratio to exceed the stated limitation in effect at the time of (i) the waiver or reimbursement and (ii) the recoupment by FAM, after repayment of the recoupment is taken into account.

Please acknowledge acceptance on the enclosed copy of this letter.

Ladies and Gentlemen:

You have requested our opinion, as your special Massachusetts counsel, as to certain matters of Massachusetts law relating to the organization and shares of The Alger Funds, a trust with transferable shares (the “Trust”) established under Massachusetts law pursuant to an Amended and Restated Declaration of Trust dated September 13, 2012, as amended to date (the “Declaration of Trust”). We understand that our opinion is requested in connection with the filing by the Trust with the Securities and Exchange Commission (the “SEC”) of Post-Effective Amendment No. 134 to its Registration Statement under the Securities Act of 1933, as amended, Registration No. 033-04959 and of Amendment No. 136 to its Registration Statement under the Investment Company Act of 1940, as amended, Registration No. 811-01355 (the “Amendment”), relating to each of Class A and Class C Shares of beneficial interest, $0.001 par value per share (collectively, the “Shares”), of Alger Mid Cap Focus Fund, a separate series of the Trust.

For purposes of rendering the opinions stated herein, we have examined and are familiar with the Declaration of Trust, and we have reviewed drafts of the prospectus (the “Prospectus”) and statement of additional information (the “SAI”) contained in the Amendment, records of the actions taken by yourselves as the Trustees of the Trust to authorize the issuance and sale of the Shares, the Amended and Restated By-Laws of the Trust, as currently in effect, certificates of officers of the Trust and of public officials as to matters of fact relevant to such opinions, and such other documents and instruments, certified or otherwise identified to our satisfaction, and such questions of law and fact, as we have considered necessary or appropriate for purposes of giving such opinions. We call to your attention that, in doing so, we have assumed the genuineness of the signatures on, and the authenticity of, all documents furnished to us, and the conformity to the originals of documents submitted to us as copies, which we have not independently verified.

Our opinion in paragraph 1 below with respect to the valid existence of the Trust in Massachusetts is based solely on a certificate to such effect issued by the Secretary of the Commonwealth of Massachusetts.

Based upon and subject to the foregoing, we hereby advise you that, in our opinion, under the laws of Massachusetts:

This letter expresses our opinions as to the provisions of the Declaration of Trust and the laws of Massachusetts applying to business trusts generally, but does not extend to the Massachusetts Securities Act, or to federal securities or other laws.

This opinion is limited to the present laws of The Commonwealth of Massachusetts (as such laws are applied by courts located in Massachusetts) and to the present judicial interpretations thereof and to the facts as they presently exist. We express no opinion with respect to, or as to the effect of the laws of, any other jurisdiction.

All of the opinions set forth herein are rendered as of the date hereof, and we assume no obligation to update such opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in the law that may hereafter occur.

This opinion letter should be interpreted in accordance with the Legal Opinion Principles issued by the Committee on Legal Opinions of the American Bar Association’s Section of Business Law, as published in 53 Business Lawyer 831 (May 1998).

This opinion is solely for the benefit of the Trust and its shareholders and may not be otherwise quoted or relied upon by any person or entity without our prior express written consent.

We consent to your filing this letter with the SEC as an exhibit to the Amendment, but we do not thereby concede that we come within the class of persons whose consent is required under Section 7 of the Securities Act.

Very truly yours,
