W I T N E S S E T H:

WHEREAS, the Manager is the manager and investment advisor to each Series of Principal Funds, Inc.,
(the "Fund"), an open-end management investment company registered under the Investment Company Act of
1940, as amended (the "1940 Act"); and

WHEREAS, the Manager desires to retain the Sub-Advisor to furnish it with investment advisory services
with respect to each series identified in Appendix A (hereinafter called the “Series”), which the Manager has
agreed to provide to the Fund, and the Sub-Advisor desires to furnish such services; and

WHEREAS, the Manager has furnished the Sub-Advisor with copies properly certified or authenticated of
each of the following and will promptly provide the Sub-Advisor with copies properly certified or authenticated of
any amendment or supplement thereto:

(a)	Management Agreement (the "Management Agreement") with the Fund;

(b)	The Fund's registration statement and financial statements as filed with the Securities and Exchange
	Commission;

(c)	The Fund's Articles of Incorporation and By-laws;

(d)	Policies, procedures or instructions adopted or approved by the Board of Directors of the Fund relating
	to obligations and services to be provided by the Sub-Advisor.

NOW, THEREFORE, in consideration of the premises and the terms and conditions hereinafter set forth, the
parties agree as follows:

1.	Appointment of Sub-Advisor

	In accordance with and subject to the Management Agreement, the Manager hereby appoints the Sub-
	Advisor to act as the Manager’s agent and attorney-in-fact with respect to the investment and
	reinvestment of assets in the Series with full power and authority to direct any custodian of the assets of
	the Series to purchase, sell or exchange any stocks, bonds, or other securities or such other assets
	which are acceptable to the Sub-Advisor (individually, "security" and collectively, "securities") and to
	issue directly to a broker or dealer such orders for the purchase, sale or exchange of securities or other
	property, as the Sub-Advisor may deem appropriate and without prior consultation with the Manager,
	subject to the control and direction of the Manager and the Fund's Board of Directors, for the period and
	on the terms hereinafter set forth. The Sub-Advisor accepts such appointment and agrees to furnish the
	services hereinafter set forth for the compensation herein provided. The Sub-Advisor shall for all
	purposes herein be deemed to be an independent contractor and shall, except as expressly provided or
	authorized, have no authority to act for or represent the Fund or the Manager in any way or otherwise be
	deemed an agent of the Fund or the Manager.

2.	Obligations of and Services to be Provided by the Sub-Advisor

	The Sub-Advisor will:

	(a) Provide investment advisory services, including but not limited to research, advice and supervision
	for the Series.

NB- 1


(b)	Furnish to the Board of Directors of the Fund for approval (or any appropriate committee of such
	Board), and revise from time to time as conditions require, a recommended investment program for
	the Series consistent with each Series investment objective and policies.

(c)	Implement the approved investment program by placing orders for the purchase and sale of
	securities without prior consultation with the Manager and without regard to the length of time the
	securities have been held, the resulting rate of portfolio turnover or any tax considerations, subject
	always to the provisions of the Fund's registration statement, Articles of Incorporation and Bylaws
	and the requirements of the 1940 Act, as each of the same shall be from time to time in effect.

(d)	Advise and assist the officers of the Fund, as requested by the officers, in taking such steps as are
	necessary or appropriate to carry out the decisions of its Board of Directors, and any appropriate
	committees of such Board, regarding the general conduct of the investment business of the Series.

(e)	Maintain, in connection with the Sub-Advisor’s investment advisory services obligations,
	compliance with the 1940 Act and the regulations adopted by the Securities and Exchange
	Commission thereunder and the Series’ investment strategies and restrictions as stated in the
	Fund’s prospectus and statement of additional information.

(f)	Report to the Board of Directors of the Fund at such times and in such detail as the Board of
	Directors may reasonably deem appropriate in order to enable it to determine that the investment
	policies, procedures and approved investment program of the Series are being observed.

(g)	Upon request, provide assistance and recommendations for the determination of the fair value of
	certain securities when reliable market quotations are not readily available for purposes of
	calculating net asset value in accordance with procedures and methods established by the Fund's
	Board of Directors.

(h)	Furnish, at its own expense, (i) all necessary investment and management facilities, including
	salaries of clerical and other personnel required for it to execute its duties faithfully, and (ii)
	administrative facilities, including bookkeeping, clerical personnel and equipment necessary for the
	efficient conduct of the investment advisory affairs of the Series. Except for expenses specifically
	assumed or agreed to be paid by the Sub-Advisor under this Agreement, the Sub-Advisor shall not
	be liable for any expenses of the Manager, the Fund or the Series including, without limitation, (i)
	interest and taxes, (ii) brokerage commissions and other costs in connection with the purchase or
	sale of securities or other investment instruments with respect to the Series, and (iii) custodian fees
	and expenses.

(i)	Open accounts with broker-dealers and futures commission merchants (“broker-dealers”), select
	broker-dealers to effect all transactions for the Series, place all necessary orders with broker-
	dealers or issuers (including affiliated broker-dealers), and negotiate commissions, if applicable. To
	the extent consistent with applicable law, purchase or sell orders for the Series may be aggregated
	with contemporaneous purchase or sell orders of other clients of the Sub-Advisor. In such event
	allocation of securities so sold or purchased, as well as the expenses incurred in the transaction,
	will be made by the Sub-Advisor in the manner the Sub-Advisor considers to be the most equitable
	and consistent with its fiduciary obligations to the Fund and to other clients. The Sub-Advisor will
	report on such allocations at the request of the Manager, the Fund or the Fund’s Board of Directors
	providing such information as the number of aggregated trades to which the Series was a party, the
	broker-dealers to whom such trades were directed and the basis for the allocation for the
	aggregated trades. The Sub-Advisor shall use its best efforts to obtain execution of transactions
	for the Series at prices which are advantageous to the Series and at commission rates that are
	reasonable in relation to the benefits received. However, the Sub-Advisor may select brokers or
	dealers on the basis that they provide brokerage, research or other services or products to the Sub-
	Advisor. To the extent consistent with applicable law, the Sub-Advisor may pay a broker or dealer
	an amount of commission for effecting a securities transaction in excess of the amount of
	commission or dealer spread another broker or dealer would have charged for effecting that

NB- 2


	transaction if the Sub-Advisor determines in good faith that such amount of commission is
	reasonable in relation to the value of the brokerage and research products and/or services provided
	by such broker or dealer. This determination, with respect to brokerage and research products
	and/or services, may be viewed in terms of either that particular transaction or the overall
	responsibilities which the Sub-Advisor and its affiliates have with respect to the Series as well as to
	accounts over which they exercise investment discretion. Not all such services or products need be
	used by the Sub-Advisor in managing the Series. In addition, joint repurchase or other accounts
	may not be utilized by the Series except to the extent permitted under any exemptive order
	obtained by the Sub-Advisor provided that all conditions of such order are complied with.

(j)	Maintain all accounts, books and records with respect to the Series as are required of an
	investment advisor of a registered investment company pursuant to the 1940 Act and Investment
	Advisers Act of 1940 (the “Investment Advisers Act”), and the rules thereunder, and furnish the
	Fund and the Manager with such periodic and special reports as the Fund or Manager may
	reasonably request. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the
	Sub-Advisor hereby agrees that all records that it maintains for the Series are the property of the
	Fund, agrees to preserve for the periods described by Rule 31a-2 under the 1940 Act any records
	that it maintains for the Series and that are required to be maintained by Rule 31a-1 under the 1940
	Act, and further agrees to surrender promptly to the Fund any records that it maintains for a Series
	upon request by the Fund or the Manager. The Sub-Advisor has no responsibility for the
	maintenance of Fund records except insofar as is directly related to the services the Sub-Advisor
	provides to a Series.

(k)	Observe and comply with Rule 17j-1 under the 1940 Act and the Sub-Advisor’s Code of Ethics
	adopted pursuant to that Rule as the same may be amended from time to time. The Manager
	acknowledges receipt of a copy of Sub-Advisor’s current Code of Ethics. Sub-Advisor shall
	promptly forward to the Manager a copy of any material amendment to the Sub-Advisor’s Code of
	Ethics along with certification that the Sub-Advisor has implemented procedures for administering
	the Sub-Advisor’s Code of Ethics.

(l)	From time to time as the Manager or the Fund may request, furnish the requesting party reports on
	portfolio transactions and reports on investments held by a Series, all in such detail as the Manager
	or the Fund may reasonably request. The Sub-Advisor will make available its officers and
	employees to meet with the Fund’s Board of Directors at the Fund’s principal place of business on
	due notice to review the investments of a Series.

(m)	Provide such information as is customarily provided by a Sub-Advisor and may be required for the
	Fund or the Manager to comply with their respective obligations under applicable laws, including,
	without limitation, the Internal Revenue Code of 1986, as amended (the “Code”), the 1940 Act, the
	Investment Advisors Act, the Securities Act of 1933, as amended (the “Securities Act”), and any
	state securities laws, and any rule or regulation thereunder.

(n)	Vote proxies received on behalf of the Series in a manner consistent with Sub-Advisor's proxy
	voting policies and procedures and provide a record of votes cast containing all of the voting
	information required by Form N-PX to enable the Series to file Form N-PX as required by SEC rule.

(o)	Respond to tender offers, rights offerings and other voluntary corporate action requests affecting
	securities held by the Fund. Notwithstanding the foregoing, the Sub-Advisor shall not be obligated
	to take any action or render advice involving legal action on the Fund’s behalf with respect to assets
	in the Series that become subject to any legal notices or proceedings, including securities class
	actions and bankruptcies. The Fund retains the right to proceed directly as a securityholder against
	the issuer of any security in the Series.


3.	Prohibited Conduct

	In providing the services described in this agreement, the Sub-Advisor will not consult with any other
	investment advisory firm that provides investment sub-advisory services to the Fund or a fund that is

NB- 3


	under common control with the Fund regarding transactions for the Fund in the securities or other assets
	allocated to the Sub-Advisor pursuant to this Agreement, except as provided by Rule 12d-3-1 under the
	1940 Act.

4.	Compensation

	As full compensation for all services rendered and obligations assumed by the Sub-Advisor hereunder
	with respect to the Series, the Manager shall pay the compensation specified in Appendix A to this
	Agreement.

5.	Liability of Sub-Advisor

	Neither the Sub-Advisor nor any of its directors, officers, employees, agents or affiliates shall be liable to
	the Manager, the Fund or its shareholders for any loss suffered by the Manager or the Fund resulting
	from any error of judgment made in the good faith exercise of the Sub-Advisor's investment discretion in
	connection with selecting investments for a Series or as a result of the failure by the Manager or any of
	its affiliates to comply with the terms of this Agreement and/or insurance laws and rules except for
	losses resulting from willful misfeasance, bad faith or gross negligence of, or from reckless disregard of,
	the duties of the Sub-Advisor or any of its directors, officers, employees, agents, or affiliates. The Sub-
	Advisor shall not have any responsibilities with respect to any assets of the Fund other than the Series.
	The Sub-Advisor shall not be responsible for any loss incurred by reason of any act or omission of any
	dealer or broker, or the Manager, or any custodian, or any other third-party service provider to the Fund
	or Series.

	The Sub-Advisor shall be responsible only for managing the Series in good faith and in accordance with
	the investment objectives, fundamental policies and restrictions, and shall have no responsibility
	whatsoever for, and shall incur no liability on account of (i) selection or establishment of such investment
	objectives, fundamental policies and restrictions (ii) advice on, or management of, any other assets for
	Manager or the Fund, (iii) filing of any tax or information returns or forms, withholding or paying any
	taxes, or seeking any exemption or refund for the Manager or the Fund, (iv) registration of the Fund or
	Series with any government or agency, or (v) administration of the plans and trusts investing through the
	Fund, (vi) overall Fund compliance with the requirements of the 1940 Act, which requirements are

	Code of 1986, as amended, which are outside of the Sub-Advisor’s control and shall be indemnified and
	held harmless by Manager for any loss in carrying out the terms and provisions of this Agreement,
	including reasonable attorney’s fees, indemnification to the Fund, or any shareholder thereof and,
	brokers and commission merchants, fines, taxes, penalties and interest. Sub-Advisor, however, shall be
	liable for any liability, damages, or expenses of Manager or the Fund arising out of the willful
	misfeasance, bad faith or gross negligence of, or from reckless disregard of, the duties of the
	Sub-Advisor or any of its directors, officers or employees.

6.	Supplemental Arrangements

	The Sub-Advisor may enter into arrangements with other persons affiliated with the Sub-Advisor or with
	unaffiliated third parties to better enable the Sub-Advisor to fulfill its obligations under this Agreement for

	approval of the Manager and, where required by applicable law, the Board of Directors of the Fund.
