	Agreement effective as of December 14, 2009, by and between PRINCIPAL FUNDS,

DISTRIBUTOR, INC., a Washington corporation (referred to herein as the "Distributor").
W I T N E S S E T H:
	WHEREAS, The Fund and the Distributor wish to enter into an agreement setting forth the
terms upon which the Distributor will act as underwriter and distributor of the Fund’s Class A,
Class B, Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5, and
Institutional Class shares of the Fund (the “Fund Shares”); and
	WHEREAS, The Fund and the Distributor have adopted procedures to implement an
Anti-Money Laundering Program reasonably designed to prevent the Fund Shares of the Fund
from being used to launder money or to support terrorist activities; and
	WHEREAS, The Fund wants to appoint the Distributor as its agent to assure the Fund's
Anti-Money Laundering Program procedures are implemented and the program is operated in
accordance with those procedures, and the Distributor is willing to accept this responsibility.
	NOW, THEREFORE, in consideration of the premises and the mutual agreements herein
contained, the Fund hereby appoints the Distributor to act as principal underwriter (as such
term is defined in Section 2(a)(29) of the Investment Company Act of 1940 (as amended)) of
the Fund Shares of Capital Stock of each of the Fund’s series (the “Series”), and each Series
hereafter offered by the Fund and the Distributor agrees to act and perform the duties and
functions of underwriter in the manner and subject to the conditions hereinafter set forth.
1.	SOLICITATION OF ORDERS
	In consideration of the rights granted herein to the Distributor, Distributor agrees to use all
	reasonable efforts, consistent with its other business, to secure purchasers for Shares of
	the Fund. This shall not prevent the Distributor from entering into like arrangements
	(including arrangements involving the payment of underwriting commissions) with other
	issuers. The Distributor shall have the right to enter into sales agreements with dealers of
	its choice for the sale of Fund Shares of the Fund to eligible purchasers as described in
	the Fund’s current Prospectus and/or Statement of Additional Information at the public
	offering price only and fix in such agreements the portion of the sales charge which may
	be retained by dealers, provided that the Fund shall approve the form of the sales
	agreement and the dealer discounts set forth therein and shall evidence such approval by
	filing said form of sales agreement and amendments thereto as an exhibit to its currently
	effective registration statement under the Securities Act of 1933 (the "1933 Act").
2.	SERVICE AGREEMENTS
	The Distributor shall have the right to enter into Service Agreements with selling dealers
	and banks or other financial institutions to provide shareholder services to the Class A,
	Class B Class C, Class J, Class R-1, Class R-2, Class R-3, Class R-4, Class R-5, and
	Institutional Class shareholders, including without limitation, services such as furnishing

	information as to the status of shareholder accounts, responding to telephone and written
	inquiries of shareholders, and assisting shareholders with tax information, provided that
	the Fund shall approve the form of Service Agreement.
3.	SALE OF SHARES
	The Distributor is authorized to sell as agent on behalf of the Fund authorized Fund
	Shares of the Fund by accepting unconditional orders placed with the Distributor by
	investors in states wherever sales may lawfully be made during the term of this
	Agreement and subject to the registration requirements of the 1933 Act.
4.	PUBLIC OFFERING PRICE
	Except as otherwise noted in the Fund’s current Prospectus and/or Statement of
	Additional Information, all shares sold to investors by the Distributor or the Fund will be
	sold at the public offering price. The public offering price for all accepted orders will be the
	net asset value per share, as determined in the manner described in the Fund’s current
	Prospectus and/or Statement of Additional Information, plus a sales charge (if any)
	described in the Fund’s current Prospectus and/or Statement of Additional Information,
	subject to any waivers or reductions in the sales charge that may be described therein.
	The Fund shall in all cases receive the net asset value per share on all sales. If a sales
	charge is in effect, the Distributor shall have the right subject to such rules or regulations
	of the Securities and Exchange Commission as may then be in effect pursuant to Section
	22 of the Investment Company Act of 1940 to pay a portion of the sales charge to its
	agents, employees and registered representatives and to dealers who have sold Fund
	Shares of the Fund. The Distributor shall receive a commission equal to the difference
	between the basic retail price and the “net asset value” of the Fund’s shares sold through
	the Distributor subject to a sales charge at the basic retail price. If any such commission is
	received by the Fund, it will pay such commission to the Distributor. If a fee in connection
	with shareholder redemptions is in effect, the Fund shall collect the fee on behalf of
	Distributor and, unless otherwise agreed upon by the Fund and Distributor, the Distributor
	shall be entitled to receive all of such fees. The Distributor may pay its agents and
	employees such compensation, allow to dealers such concessions, and allow (and
	authorize dealers to re-allow) such discounts to purchasers, as the Distributor may
	determine from time to time. The Distributor may also purchase as principal Fund Shares
	of the Fund at “net asset value” and sell such shares at the public offering price.
5.	AUTHORIZED REPRESENTATIONS
	The Distributor is not authorized by the Fund to give any information or to make any
	representations other than those contained in the appropriate registration statement or
	Prospectus and Statement of Additional Information filed with the Securities and
	Exchange Commission under the 1933 Act (as these registration statements,
	Prospectuses and Statements of Additional Information may be amended from time to
	time), or contained in shareholder reports or other material that may be prepared by or on
	behalf of the Fund for the Distributor’s use. This shall not be construed to prevent the
	Distributor from preparing and distributing sales literature or other material as it may deem
	appropriate.
6.	DELIVERY OF PAYMENTS AND ISSUANCE OF SHARES
	The Distributor will deliver to the Fund all payments made pursuant to orders accepted by
	the Distributor upon receipt thereof by the Distributor in its principal place of business.

	After payment the Fund will issue shares of the applicable class of Capital Stock by
	crediting the appropriate number of shares to a stockholder account in such names and
	such manner as specified in the application or order relating to such shares.
7.	SALE OF SHARES TO INVESTORS BY THE FUND
	Any right granted to the Distributor to accept orders for shares or make sales on behalf of
	the Fund will not apply to Fund Shares issued in connection with the merger or
	consolidation of any other investment company with the Fund or its acquisition, purchase
	or otherwise, of all or substantially all the assets of any investment company or
	substantially all the outstanding shares of any such company. Also, any such right shall
	not apply to Fund Shares issued, sold or transferred, whether Treasury or newly issued
	shares, that may be offered by the Fund to investors on applications received and
	accepted by the Fund or to its shareholders, as stock dividends or splits for not less than
	"net asset value".
8.	AGREEMENTS WITH DEALERS OR OTHERS
	In making agreements with any dealers or others, the Distributor shall act only in its own
	behalf and in no sense as agent for the Fund and shall be agent for the Fund only in
	respect of sales and repurchases of Fund shares.
9.	COPIES OF CORPORATE DOCUMENTS
	The Fund will furnish the Distributor promptly with properly certified or authenticated
	copies of any registration statements filed by it with the Securities and Exchange
	Commission under the 1933 Act, as amended, or the Investment Company Act of 1940,
	as amended, together with any financial statements and exhibits included therein and all
	amendments or supplements thereto hereafter filed. Also, the Fund shall furnish the
	Distributor, at the Distributor’s expense, with a reasonable number of printed copies of
	each semi-annual and annual report (quarterly if made) of the Fund as the Distributor may
	request, and shall cooperate fully in the efforts of the Distributor to sell and arrange for the
	sale of the Fund's shares of Capital Stock and in the performance by the Distributor of all
	of its duties under this Agreement.
10.	RESPONSIBILITY FOR CONTINUED REGISTRATION INCLUDING INCREASE IN
	SHARES
	The Fund will assume the continued responsibility for meeting the requirements of
	registration under the 1933 Act, as amended, under the Investment Company Act of 1940,
	as amended, and under the securities laws of the various states where the Distributor is
	registered as a broker-dealer. The Fund, subject to the necessary approval of its
	shareholders, will increase the number of authorized shares from time to time as may be
	necessary to provide the Distributor with such number of shares as the Distributor may
	reasonably be expected to sell.
11.	SUSPENSION OF SALES
	If and whenever the determination of asset value of a Series is suspended pursuant to
	applicable law, and such suspension has become effective, until such suspension is
	terminated no further applications for shares of the Series shall be accepted. In addition,
	the Fund reserves the right to suspend sales and the Distributor's authority to accept
	orders for shares on behalf of the Fund, if in the judgment of the majority of its Board of
	Directors, or of its Executive Committee if such Committee exists, it is in the best interest
	of the Fund to do so, suspension to continue for such period as may be determined by

	such majority; and in that event no shares of that Series will be sold by the Fund or by the
	Distributor on behalf of the Fund while such suspension remains in effect except for
	shares necessary to cover unconditional orders accepted by the Distributor before the
	Distributor had knowledge of the suspension.
12.	RESPONSIBILITY FOR IMPLEMENTING THE FUND'S ANTI-MONEY LAUNDERING
	PROGRAM
	The Fund hereby appoints the Distributor to act as its agent to assure the Fund's Anti-
	Money Laundering Program procedures applicable to Fund Shares are implemented and
	the Distributor accepts this appointment. The Distributor will assure such procedures are
	implemented and that the program operates in accordance with those procedures and will
	provide such reports and information as the Fund may request from time to time to
	facilitate the Fund's oversight of such program. The Distributor will also make information
	and records relating to the Fund's Anti-Money Laundering Program available to federal
	regulators as required by law and will permit such regulators to examine and inspect the
	Distributor for purposes of the program. The Distributor will perform the specific
	requirements of the Fund’s Customer Identification Program and will annually certify it has
	implemented the Fund’s anti-money laundering program.
13.	EXPENSES
	The Fund will pay (or will enter into arrangements providing for the payment of) all fees
	and expenses: (1) in connection with the preparation and filing of any registration
	statement or amendments thereto as required under the Investment Company Act of

	for the payment of) the expense of printing prospectuses used for the solicitation of new
	accounts of the Fund. The Distributor will pay (or will enter into arrangements providing
	for the payment of) the expenses of other sales literature for the Fund, will pay all fees
	and expenses in connection with the Distributor's qualification as a dealer under the
	Securities Exchange Act of 1934, as amended, and in the various states, and all other
	expenses in connection with the sale and offering for sale of shares of the Fund which
	have not been herein specifically allocated to or assumed by the Fund.
	As provided in the Distribution and Service Plan adopted by the Fund, it is recognized by
	the Fund that Principal Management Corporation (the “Manager”) may make payment to
	the Distributor with respect to any expenses incurred in the distribution of shares of the
	Fund, such payments payable from the past profits or other resources of the Manager
	including management fees paid to it by the Fund.

	The Fund recognizes that the Distributor is now a member of the Financial Industry
	Regulatory Authority, and in the conduct of its duties under this Agreement the Distributor
	is subject to the various rules, orders and regulations of such organization. The right to
	determine whether such membership should or should not continue, or to join other
	organizations, is reserved by the Distributor.
16.	OTHER INTERESTS
	It is understood that directors, officers, agents and stockholders of the Fund are or may

17.	INDEMNIFICATION
	The Fund agrees to indemnify, defend and hold the Distributor, its officers and directors,

	Act, free and harmless from and against any and all claims, demands, liabilities and
	expenses (including the cost of investigating or defending such claims, demands or
	liabilities and any counsel fees incurred in connection therewith) which the Distributor, its
	officers, directors or any such controlling person may incur under the Securities Act of
	1933, or under common law or otherwise, arising out of or based upon any untrue
	statement of a material fact contained in the Fund's registration statement, Prospectus or
	Statement of Additional Information or arising out of or based upon any alleged omission
	to state a material fact required to be stated therein or necessary to make the statements
	in either or necessary to make the statements therein not misleading, except insofar as
	such claims, demands, liabilities or expenses arise out of or are based upon any such
	untrue statement or omission made in conformity with information furnished in writing by
	the Distributor to the Fund for use in the Fund's registration statement or Prospectus or
	Statement of Additional Information: provided, however, that this indemnity agreement, to
	the extent that it might require indemnity of any person who is also an officer or director of

	precedent that such result would not be against public policy as expressed in the
	Securities Act of 1933, and further provided, that in no event shall anything contained

	of its reckless disregard of its obligations under this Agreement. The Fund's agreement to
	indemnify the Distributor, its officers and directors and any such controlling person as

	expenses (including the cost of investigating or defending such claims, demands liabilities
	and any counsel fees incurred in connection therewith) which the Fund, its directors or
	officers or any such controlling person may incur under the 1933 Act or under common
	law or otherwise; but only to the extent that such liability or expense incurred by the Fund,
	its directors or officers or such controlling person resulting from such claims or demands
	shall arise out of or be based upon any alleged untrue statement of a material fact
	contained in information furnished in writing by the Distributor to the Fund for use in the
	Fund's registration statement, Prospectus or Statement of Additional Information or shall
	arise out of or be based upon any alleged omission to state a material fact in connection
	with such information required to be stated in the registration statement, Prospectus or
	Statement of Additional Information or shall arise out of or be based upon any alleged
	omission to state a material fact in connection with such information required to be stated
	in the registration statement or Prospectus or necessary to make such information not
	misleading. The Distributor's agreement to indemnify the Fund, its directors and officers,
	and any such controlling person as aforesaid is expressly conditioned upon the Distributor
	being promptly notified of any action brought against the Fund, its officers or directors or
	any such controlling person.
18.	DURATION AND TERMINATION OF THIS AGREEMENT
	This Agreement shall become effective as of the execution date specified on page 1 of

	Agreement be made in order to comply with the recommendations or requirements of the
	Securities and Exchange Commission or other governmental authority or to obtain any
	advantage under state or federal tax laws and should notify the Distributor of the form of

21.	SPECIAL RULES FOR COMPENSATION OF DISTRIBUTOR IN RESPECT OF CLASS B
	SHARES
	In consideration of the Distributor’s role in the distribution of the Class B shares of each
	Series of the Fund (including the Class B shares of such Series issued in connection with
	its acquisition of the assets of a fund of WM Trust I, WM Trust II or WM Strategic Asset
	Management Portfolios, LLC ( the “Washington Mutual Funds”), the Fund shall: (i) pay
	the Distributor its “Allocable Portion,” as defined below, of the maximum distribution fee
	contemplated by the Fund’s Distribution Plan and Agreement – Class B Shares for each
	Series as in effect on the date hereof (the “Plan”) and (ii) withhold and pay over to the
	Distributor upon redemption of each Class B share of each Series, the contingent
	deferred sales charges contemplated by the Prospectus for the Fund (which in the case of
	Class B shares issued in connection with the Fund’s acquisition of the assets of any fund
	of the Washington Mutual Funds shall be computed in accordance with Appendix A
	hereto) to be withheld from Class B shares of each Series that would be attributable to the
	Distributor under the principles described below for determining the Distributor’s Allocable
	Portion of the distribution fee.
	Notwithstanding anything to the contrary elsewhere in this Agreement or the Plan:
	1.	The distribution fee accrues daily at the rate of 75 basis points per annum on the
		average daily net asset value of all of the outstanding Class B shares of each Series,
		including Class B shares issued in connection with the Fund’s acquisition of assets of
		the Washington Mutual Funds, subject to the applicable rules of FINRA, and shall be
		paid monthly as promptly as possible after the last day of each month but in any
		event prior to the tenth day of the following calendar month;
	2.	The Distributor’s Allocable Portion in respect of each Series shall be 100% until such
		time as it shall be replaced as Distributor of the Class B shares of the Series;
		thereafter, its Allocable Portion shall be the portion of the total distribution fee
		accruing in respect of outstanding Class B shares of the Series as is fairly attributable
		to the portion of such outstanding Class B shares that are outstanding when the
		Distributor ceases to serve in that capacity or are later issued as dividends or other
		distributions in respect of such Class B shares or in free exchanges for Class B
		shares of other Series or other funds for which the Distributor acts as principal
		distributor that are fairly attributable to the Distributor on the same basis; and the
		Allocable Portion of each subsequent distributor (a “Subsequent Distributor”) shall be

	the portion of such outstanding Class B shares that were sold by the Fund during the
	period such Subsequent Distributor served as distributor or were later issued as
	dividends or other distributions in respect of such Class B shares or in free
	exchanges for Class B shares of other Series or funds for which such Subsequent
	Distributor acts as principal distributor that are fairly attributable to such Subsequent
	Distributor on the same basis; it being understood that the Fund and the Distributor
	shall agree on procedures for making these allocations (the “Allocation Procedures”);
3.	The Distributor shall be deemed to have fully earned its Allocable Portion of the
	distribution fee payable in respect of Class B shares of a Series as of any point in
	time upon the sale of the outstanding commission shares (i.e., those that are initially
	subject to contingent deferred sales charges under circumstances set forth in the
	Prospectus for such shares whether or not such shares are later released from that
	obligation) of such Series as of such point in time;
4.	The Distributor hereby directs the Fund, and the Fund hereby agrees, to pay all of the
	Distributor’s Allocable Portion of the distribution fee, as may be more specifically
	directed by the Distributor in Irrevocable Payment Instructions, to persons which have
	provided funds to the Distributor to cover or otherwise enable the incurring of
	expenses associated with services in connection with the distribution of the Class B
	shares of the funds of the Washington Mutual Funds in exchange for the assets of
	which Class B shares of the Fund were issued; and
5.	The Fund’s obligation to pay the Distributor (or an assignee of the Distributor) its
	Allocable Portion of the distribution fee as provided hereby shall be absolute and
	unconditional and not subject to offset or counterclaim and shall not be terminated or
	modified (including without limitation, by change in the rules applicable to the
	conversion of the Class B shares into shares of another class) for any reason
	(including a termination of the Plan, a termination of the Distributor as distributor of
	the Class B shares of the Fund or any Series thereof or a termination of this
	Agreement) except:
	a.	To the extent required by a change in the Investment Company Act of 1940
		(the “1940 Act”), the rules and regulations under the 1940 Act, the Conduct
		Rules of the Financial Industry Regulatory Authority (“FINRA”), or any judicial
		decisions or interpretive pronouncements by the Securities and Exchange
		Commission or its staff, which is either binding upon the Distributor or generally
		complied with by similarly situated distributors of mutual fund shares;
	b.	on a basis which does not alter the Distributor’s Allocable Portion of the
		distribution fee computed with reference to shares of the Fund or any Series
		thereof or any other fund for which it acts as distributor that were outstanding
		immediately prior to such termination or modification or which are thereafter
		issued directly or indirectly as a result of dividends or other distributions or free
		exchanges of such shares; or
	c.	in connection with a “Complete Termination” of the Plan by the Fund, and for
		this purpose: (1) a “Complete Termination” of the Plan for the Class B shares
		of a Series shall occur only if and only so long as the Plan is terminated for
		such Class B shares and following such termination, no distribution fees are
		imposed either on such Class B shares or on any “Similar Class” of shares of
		such Series; (2) a “Similar Class” is any class of shares of such Series that has
		a sales load structure substantially similar to that of the class for which this
		Plan was terminated, taking into account the total sales load borne directly or
		indirectly by holders of such class of shares including commission paid directly

	by such holders to brokers on issuance of shares of such class, asset based
	sales charges paid by the Fund/Series and allocated to shares of such class,
	contingent deferred sales charges payable by holders of shares of such class,
	installment or deferred sales charges payable by holders of shares of such
	class, and similar charges borne directly or indirectly by holders of shares of
	such class; and (3) a class of shares would not be considered substantially
	similar to the Class B shares if (I) a front end sales charge is paid by the
	purchaser, or (II)(A) the shares are purchased at net asset value, (B) any
	commission paid up front to any selling agent(s) does not exceed 1.0% of the
	purchase amount, (C) the period during which any contingent deferred sales
	charge applies does not exceed 12 months from the purchase date, and (D)
	there is no other sales load feature borne directly or indirectly by holders of
	such class of shares.
6.	This Section 21 is not intended to, and shall not, prohibit the Fund from issuing and
	selling a Similar Class (as defined in paragraph 5(c)(2) above) of any Series; but is
	merely intended to prohibit the Fund from treating a termination of the Plan in
	respect of Class B shares of any Series as a "Complete Termination" for purposes
	of paragraph 5(c)(1) of this Section 21 while it continues to issue a Similar Class.
7.	The Fund’s obligations under this Section 21 of the Agreement shall terminate upon
	the Fund’s payment in full to the Distributor and each Subsequent Distributor, if any,
	such distributor’s Allocable Portion in respect of each Series.

             IN WITNESS WHEREOF, the parties hereof have caused this Agreement to be executed
