 MUELLER WATER PRODUCTS, INC. 
 SECOND AMENDED AND
RESTATED 2006 STOCK INCENTIVE PLAN 
 STOCK OPTION AGREEMENT 
 1. Grant of Option. The Company hereby grants to the Optionholder named in the Notice of Grant attached to this Agreement (the
“Optionholder”) an option (the “Option”) to purchase the number of shares of Series A Common Stock (“Shares”) of the Company, as set forth in the Notice of Grant, at the exercise price per share set forth in the Notice
of Grant (the “Exercise Price”), subject to the terms and conditions of the Plan, which is incorporated by reference into this Stock Option Agreement (the “Option Agreement”), the Option Agreement and the Notice of Grant. In the
event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this
Option is intended to be an Incentive Stock Option, to the extent that the aggregate Fair Market Value of the Common Stock subject to the Option (as determined at the time of grant) exceeds the $100,000 rule of Code Section 422(d), it shall be
treated as a Nonstatutory Stock Option (“NSO”). 
 2. Exercise of Option. 
 (a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in
the Notice of Grant and the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of
Exercise. This Option is exercisable by delivery of an exercise notice, in the form attached hereto (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares in respect of which the Option is
being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan and the Option Agreement. The Exercise Notice shall be completed by the
Optionholder and delivered to the Company’s Stock Plan Administrator, as designated by the Company from time to time. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. The
Optionholder shall also be required to make adequate provision for all withholding taxes relating to the exercise of the Option as a condition to the exercise of the Option. This Option shall be deemed to be exercised only upon receipt by the
Company of such fully executed Exercise Notice accompanied by the payment of such aggregate Exercise Price and arrangement for the adequate provision for the withholding taxes relating to the exercise. 
 (c) Compliance. No Shares shall be issued pursuant to the exercise of this Option unless such issuance, exercise, and
the method of payment of consideration for such Shares complies with Applicable Law. This Option may not be exercised for a fraction of a share. Assuming such compliance, for income tax purposes the Exercised Shares shall be considered transferred
to the Optionholder on the date the Option is exercised with respect to such Exercised Shares. Notwithstanding the foregoing, the Company shall not be liable to the Optionholder for damages relating to any delays in issuing the certificates for the
Exercised Shares to the Optionholder, any loss of the certificates, or any mistakes or errors in the issuance f the certificates or in the certificates themselves. 
 3. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionholder: 
 (a) cash or check; 
 (b) consideration received by the Company under a “same day sale” program implemented by the Company in connection with the Plan; or 
  

 3 







 (c) by delivery to the Company of other shares of Common Stock of the
Company; provided, however, that if the Exercise Price of Shares acquired pursuant to this Option is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, the Exercise Price shall be paid only by
shares of the Common Stock of the Company that have been held by the Optionholder for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). The Optionholder
may, subject to procedures satisfactory to the Board, satisfy such delivery requirement by presenting proof of beneficial ownership of such Common Stock. 
 4. Period for Exercise. Subject to the provisions of the Plan, the Notice of Grant and this Option Agreement, the Optionholder may exercise this Option as to any vested Shares at any time prior
to the earliest to occur of the following: 
 (a) the Term/Expiration Date set forth in the Notice of
Grant; 
 (b) two (2) years following the date of the Optionholder’s termination of Continuous
Service as a result of death, Disability or Retirement; 
 (c) three (3) months following the date of
the Optionholder’s termination of Continuous Service by the Company without Cause (and other than as a result of death, Disability or Retirement) or by the Optionholder for any reason; and 
 (d) the date of the Optionholder’s termination of Continuous Service by the Company for Cause. 
 5. Non-Transferability of Option. This Option may not be transferred in any manner other than by will or by the laws of descent or
distribution and may be exercised during the lifetime of the Optionholder only by the Optionholder. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the
Optionholder. 
 6. Notice of Disqualifying Disposition of ISO Shares. If the Optionholder sells or otherwise
disposes of any of the Shares acquired pursuant to an ISO (“ISO Shares”) on or before the later of (i) two years after the grant date, or (ii) one year after the exercise date, the Optionholder shall immediately notify the
Company in writing of such disposition. The Optionholder understands and agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized from such early disposition of ISO Shares by payment in cash
or out of the current earnings paid to the Optionholder. 
 7. Lock-Up. By exercising the Option, the Optionholder
agrees that the Company (or a representative of the underwriter(s)) may, in connection with the first underwritten registration of the offering of any equity securities of the Company under the Securities Act (and/or any underwritten registration of
any securities of the Company prior to that time), require that the Optionholder not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic
effect as a sale, any shares of Common Stock or other securities of the Company held by the Optionholder, for a period of time specified by the underwriter(s) (not to exceed one hundred eighty (180) days) following the effective date of the
registration statement of the Company filed under the Securities Act. The Optionholder further agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the
foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop transfer instructions with respect to Shares of Common Stock until the end of such period. The underwriters of
the Company’s stock are intended third party beneficiaries of this section and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 8. Entire Agreement; Governing Law. The Plan and the Notice of Grant are incorporated herein by reference. Except as expressly set
forth in the Notice of Grant, the Plan, the Notice of Grant and this Option Agreement constitute the entire agreement of the parties with respect 

  

 4 







 
to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionholder with respect to the subject matter hereof. The Company may
amend the terms of the Option; provided that the rights under any Option shall not be materially impaired by any such amendment except by means of a writing signed by the Company and the Optionholder. The Option is governed by the law of the State
of Delaware, without regard to the principles of conflicts of law. 
 9. NO GUARANTEE OF CONTINUED SERVICE. THE
OPTIONHOLDER ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS AN EMPLOYEE, DIRECTOR, OR CONSULTANT AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING
GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). THE OPTIONHOLDER FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS AN EMPLOYEE, DIRECTOR, OR CONSULTANT FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH THE OPTIONHOLDER’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONHOLDER’S
RELATIONSHIP (I) AS AN EMPLOYEE AT ANY TIME, WITH OR WITHOUT CAUSE; (II) AS A CONSULTANT PURSUANT TO THE TERMS OF OPTIONHOLDER’S AGREEMENT WITH THE COMPANY OR AN AFFILIATE; OR (III) AS A DIRECTOR PURSUANT TO THE BYLAWS OF THE COMPANY, AND
ANY APPLICABLE PROVISIONS OF THE CORPORATE LAW OF THE STATE OR OTHER JURISDICTION IN WHICH THE COMPANY IS DOMICILED, AS THE CASE MAY BE.

market value of $            , as to which I am attesting ownership pursuant to the form of Tender of Already-Owned Shares by Attestation of Share Ownership Rather than Physical

 3. Tax Withholding. Purchaser has contacted the Company’s Stock Plan Administrator to confirm that the tax withholding due upon exercise of the Option is

Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 (b) Purchaser agrees:
(i) to provide such additional documents as the Company may require pursuant to the terms of the Plan, (ii) to provide for the payment by Purchaser to the Company (in the manner designated by the Company) of the Company’s withholding
obligation, if any, relating to the exercise of this Option, and (iii) if this exercise relates to an ISO, to notify the Company in writing promptly after the date of any disposition of any of the Shares of Common Stock issued upon exercise of

acquired by the Purchaser for his or her own account (or otherwise in compliance with applicable law) upon exercise of the Option as set forth above: 
 (i) If Purchaser is an officer and/or director of the Company, Purchaser has contacted the Company’s Stock Plan Administrator to determine whether he or she is subject to Section 16 of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), and if so: 
  

 6 








	 	•	 	 Purchaser has reviewed his or her transactions relative to Section 16 of the Exchange Act (“Section 16”); 



 

	 	•	 	 The Company has informed the Purchaser that the grant of the Option is exempt from Section 16(b) of the Exchange Act either because (i) it
was approved by the Company’s Board of Directors or a committee duly authorized by the Board pursuant to the rules issued under Section 16, or (ii) Purchaser has held the Option for six (6) months or more, and, therefore, this
transaction may not be matched with a non-exempt purchase; and 


  

	 	•	 	 Purchaser understands that the filing of a Form 4 with the U.S. Securities and Exchange Commission may be required because of this transaction.



 (ii) Purchaser understands that if he or she is an officer and/or director of the Company,

Option shall have endorsed thereon appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to Applicable Law. Purchaser agrees that the Shares are being acquired in accordance with and
subject to the terms, provisions and conditions of his or her option documents and the Plan, to all of which the Purchaser hereby expressly assents. This agreement shall inure to the benefit of and be binding upon the Purchaser’s heirs,
executors, administrators, successors and assigns. 
 (iv) If Purchaser is selling some or all of these Shares in
accordance with the terms of the Company’s “same day sale” program, Purchaser does not have access to, nor is Purchaser aware of, any nonpublic, material information regarding the Company that could or has influenced his or her
decision to sell these Shares. 
 (v) Purchaser hereby agrees to notify the Company upon the transfer or sale or
other disposition of the Shares acquired under any ISO exercise and agrees to hold harmless the Company regarding the reporting of income subject to the disposition of these Shares. 
 (vi) Purchaser further acknowledges that he or she has received a copy of the prospectus prepared by the Company, which
provides information regarding the Company, the Plan and the Shares. 
 (vii) Purchaser represents that he or she
is entitled to exercise the Option with respect to the number of Shares that the Purchaser wishes to purchase hereby. 
 (d) Purchaser agrees that, if required by the Company (or a representative of the underwriters) in connection with the first underwritten registration of the offering of any equity securities of the Company under the Securities Act (or any
underwritten registration of the offering of any securities of the Company prior to that time), or the similar laws of a foreign jurisdiction, Purchaser will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase
of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Shares or other securities of the Company held by Purchaser, for a period of time specified by the underwriter(s) (not to exceed one hundred eighty
(180) days) following the effective date of the registration statement of the Company filed under the Securities Act. Purchaser further agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the
underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Shares until the end of
such period. 
 4. Rights as Stockholder. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the 

  

 7 







 
Shares of the Company’s Common Stock subject to the Option, notwithstanding the exercise of the Option. The Shares so acquired shall be issued to the Optionholder as soon as practicable
after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date of issuance, except as provided in the Plan. 
 5. Tax Consultation. Purchaser understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s
purchase or disposition of the Shares. Purchaser represents that Purchaser has consulted with any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying on the Company
for any tax advice. 
 6. Entire Agreement; Governing Law. The Plan, the Notice of Grant and Option Agreement are
incorporated herein by reference. This agreement, the Plan, the Notice of Grant and the Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings
and agreements of the Company and Purchaser with respect to the subject matter hereof, and may not be modified adversely to the Purchaser’s interest except by means of a writing signed by the Company and Purchaser. This agreement is governed by
