Exhibit 10.13

FORM OF WINDY CITY INVESTMENTS HOLDINGS, L.L.C.

DEFERRED UNIT GRANT AGREEMENT

This Deferred Unit Grant Agreement (this “Agreement”) is made as of [            ], between Nuveen Investments, Inc., a Delaware corporation (the “Company”), and the undersigned below (“Executive”). Capitalized terms used but not otherwise defined herein or in the LLC Agreement (as amended from time to time and in accordance with the provisions thereof) shall have the meanings set forth in Section 9 hereof.

WHEREAS, the Company desires to grant the Executive the right to receive the number of deferred Class A Units indicated on the attached Exhibit A as an incentive to remain with the Company (the “Deferred Units”);

NOW THEREFORE, in consideration of the premises and the mutual promises herein made, the Company and the Executive hereby agree as follows:

1.                                       Grant of Deferred Units. Subject to the terms of this Agreement, the Company hereby grants, effective as of the date hereof, to the Executive the number of Deferred Units indicated in Exhibit A, each of which represents the right to receive, subject to the terms of this Agreement, one Class A Unit with a Liquidation Value and all other terms and conditions equivalent to all then outstanding Class A Units.

2.                                       Accounts

(a)                                  Executive Accounts. The Company will establish a separate notional account (the “Deferred Unit Account”) for the Executive and will record in such account the aggregate number of Deferred Units granted to the Executive under this Agreement, the vesting of any Deferred Units, and any distributions made with respect to such Deferred Units as provided in Section 4.

(b)                                 Corporate Adjustments.

(i)                                     In the event that any distribution (in the form of Class A Units, other securities or other property), recapitalization, unit split, reverse unit split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, conversion of Holdings from a limited liability company to a corporation, change of control or exchange of Class A Units or other securities of Holdings, or other transaction or event involving Holdings or Class A Units (each a “Company Event”) affects the Deferred Units such that the Board determines an adjustment is necessary or appropriate in order to prevent dilution or enlargement of benefits or potential benefits intended to be made available under this Agreement, the Board shall equitably adjust any or all of the number of Class A Units or other securities (or number and kind of other securities or property) subject to the Deferred Units or take such other action as the Board determines to be appropriate to preserve the value, rights and benefit of any affected Deferred Units granted hereunder. Notwithstanding the foregoing, nothing herein shall be deemed to provide the Executive with any rights to an adjustment in respect of the Deferred Units in the event Holdings issues additional Units (as defined in the LLC Agreement), warrants,

options or other rights to purchase or otherwise acquire Units in exchange for equivalent value (in cash, in kind or in services) as determined in the sole discretion of the Board.

(ii)                                  If Holdings enters into or is involved in any Company Event, the Board may, prior to such Company Event and effective upon such Company Event, take such action as it deems appropriate, including, but not limited to, replacing Deferred Units with substitute awards in respect of the Class A Units, other securities or other property of the surviving entity or any affiliate of the surviving entity on such terms and conditions, including without limitation, as to the number of securities or amount of property, pricing and value of such securities or property or otherwise, which shall substantially preserve the value, rights and benefits of any affected Deferred Units granted hereunder as of the date of the consummation of the Company Event.

(iii)                               Upon receipt by the Executive of any such substitute awards (or payment) as a result of any such Company Event, the Executive’s Deferred Units shall be thereupon cancelled without the need for obtaining the consent of the Executive.

3.                                       Vesting.

(a)                                  General. Each of the Deferred Units issued hereunder shall be subject to vesting as set forth in this Section 3. Deferred Units which have become vested pursuant to this Section 3 are referred to herein as “Vested Deferred Units,” and Deferred Units which have not become Vested Units are referred to herein as “Unvested Deferred Units.” Subject to the last sentence of this Section 3(a), the Deferred Units shall vest quarterly pro-rata beginning on the Restatement Date and ending on the fifth anniversary of the Restatement Date; provided that upon a Liquidity Event other than an IPO or a Special Liquidity Event (as such term is defined in the Executive’s Class B Unit Grant Agreement), all outstanding Deferred Units that are then Unvested Deferred Units shall become Vested Deferred Units on the same basis, at the same time and in the same proportion as the Executive’s Time Vested Units (as such term is defined in the Executive’s Class B Unit Grant Agreement) become vested under the Executive’s Class B Unit Grant Agreement. The number of Deferred Units that are Vested Deferred Units shall not increase after Executive ceases to be an employee of, or after termination of Executive’s services to, the Company or any of its Subsidiaries; provided, however, that in the event Executive ceases to be employed by, or to provide services to, the Company or any of its Subsidiaries due to Executive’s death or Disability, all of the Deferred Units which have not yet become Vested Deferred Units shall immediately vest and become Vested Deferred Units. If and to the extent that the Executive has satisfied his or her individual performance criteria as determined by the Board (or an appropriate committee thereof), previously established by the Company’s Chief Executive Officer and approved by the Board (or an appropriate committee thereof), full vesting of all unvested Deferred Units granted under this Agreement will be accelerated to the third anniversary of the Restatement Date.

(b)                            Cancellation of Deferred Units. If Executive’s employment with the Company and its Subsidiaries and the services Executive provides to the Company and all of its Subsidiaries terminate for any reason, all Unvested Deferred Units shall be automatically cancelled on the date of termination without any consideration paid therefor and without further action on the part of the Company or any holder of any of the Unvested Deferred Units.

2

4.                                  Cash Distribution Rights. The Executive shall be entitled to receive all cash distributions paid with respect to the Class A Units credited to his or her Deferred Unit Account, provided that any such distribution credited to the Executive’s Deferred Unit Account by the Company on behalf of the Executive shall be paid (by the Company or by Windy Holdings) only at the time the underlying Deferred Unit is settled pursuant to Section 5 and only if such Deferred Unit is a Vested Deferred Unit on the Settlement Date (as defined below). Any such cash distributions shall be notionally invested in accounts or other programs to be offered by the Board at its reasonable discretion. For the sake of clarity, the Executive shall forfeit any distributions related to Unvested Deferred Units upon any forfeiture of such Unvested Deferred Unit.

5.                                  Settlement

(a)                             General. Upon the earliest to occur (the “Settlement Date”) of (i) a Liquidity Event other than an IPO which also constitutes a change in control event within the meaning of Code § 409A(a)(2)(A)(v) and the regulations promulgated thereunder, (ii) the date that is 30 days following Executive’s Separation from Service with the Company (or, if Code § 409A(a)(2)(B)(i) applies to the Company and the Executive is a Key Employee immediately prior to such termination, the date that is six months following such termination) and (iii) February 15, 2013, the Executive shall, subject to Section 2(b)(i), receive a distribution of the amounts credited to the Executive’s Deferred Unit Account, including all distributions credited to the Executive’s Deferred Unit Account pursuant to Section 4 with respect to such Deferred Units. On or before any Settlement Date, the Executive shall become a party to the LLC Agreement, the Registration Agreement, the Unitholders Agreement and a Class A Unit Purchase Agreement (or equivalent agreement with respect to other securities or property, if applicable) (the “Unit Purchase Agreements”) in form and substance reasonably consistent with such agreements in effect on or about the date hereof. Except as set forth herein, all distributions hereunder shall be made in kind with respect to securities and other property credited to an Executive’s Deferred Unit Account.

(b)                            Cash in Lieu of Property. Notwithstanding any other provision of this Agreement, if the Settlement Date is by reason of Section 5(a)(ii) (a Separation from Service) then in lieu of delivering Class A Units or other securities or property credited to the Executive’s Deferred Unit Account in respect of all or a portion of the Deferred Units, the Company may deliver to the Executive an amount of cash equal to the Liquidation Value of such Class A Units or the Fair Market Value of such other securities or property.

(c)                             Settlement in Stock of Windy Holdings. Notwithstanding any other provision of this Agreement, in lieu of delivering Class A Units or other securities or property credited to the Executive’s Deferred Unit Account (other than cash distributions pursuant to Section 4) in respect of all or a portion of the Vested Deferred Units, the Company or Windy Holdings may deliver shares of stock of Windy Holdings having a Fair Market Value equal to the Liquidation Value of such Class A Units or the Fair Market value of such other securities or property as of the date that such shares, securities or property would otherwise be delivered. If a distribution is made in the form of stock of Windy Holdings (or any replacement equity) and if Holdings exists at the time of such distribution, the Company may, in its sole discretion, require the Participant to agree to exchange such Windy Holdings stock (or replacement equity) after the distribution

3

for Units or nonvoting equity interests of Holdings (or replacement equity) in an amount of Class A Units (or replacement equity) with a Liquidation Value equal to the Fair Market Value of Windy Holdings Stock (or replacement equity) so exchanged.

(d)                                 Withholding. Except as provided in Section 5(e), Executive shall be required to remit in cash to the Company all required withholding amounts associated with settlement of the Deferred Units, as determined by the Company in its reasonable discretion. Subject to applicable law, Executive agrees that the Company may satisfy withholding obligations from any source of funds available to the Company and otherwise payable to Executive, including salary or bonus payments.

(e)                                  Notwithstanding Section 5(d) and subject to the procedures specified by the Company from time to time, the Executive may satisfy all or part of the tax withholding obligations in connection with a Deferred Unit or the settlement thereof by (a) having the Company withhold Class A Units or other securities or property credited to the Executive’s Deferred Unit Account otherwise deliverable pursuant to Section 5 with a Liquidation Value or Fair Market Value, as the case may be, equal to the Company’s minimum statutory withholding requirements, or (b) having the Executive deliver to the Company already-owned Class A Units having a Liquidation Value equal to the amount required to be withheld, provided such Class A Units shall have been held by the Executive for at least six months; and provided further that this Section 5(e) shall not apply to Executive if the Settlement Date is a Separation from Service that occurs on account of either a resignation by the Executive without Good Reason or a termination of Executive by the Company and its Subsidiaries for Cause, and provided, further, that this Section 5(e) shall not apply if, and to the extent that, the Board determines that its application poses a material risk of jeopardizing the Company’s or its Subsidiaries’ proper capitalization, liquidity, ability to satisfy its then existing or anticipated capital requirements or compliance with applicable covenants in its credit or finance agreements.

6.                                       Administration.

(a)                                  Authority of the Board. The Board shall have all powers and discretion necessary or appropriate to administer this Agreement and to control its operation, including, but not limited to, the power to (i) interpret and construe this Agreement, (ii) adopt such rules as it deems necessary or appropriate for the administration, interpretation and application of this Agreement, (iii) interpret, amend or revoke any such procedures or rules, (iv) correct any technical defect(s) or technical omission(s), or reconcile any technical inconsistency(ies), in this Agreement, and (v) make all other decisions and determinations that may be required pursuant to this Agreement or as the Board deems necessary or advisable to administer this Agreement provided that such actions will be taken in a manner reasonably consistent with the terms of this Agreement.

(b)                                 Actions of the Board. The actions of the Board shall be taken in accordance with the terms and conditions of the LLC Agreement. The Board’s determinations need not be uniform with respect to all holders of Deferred Units, and may be made selectively among holders of Deferred Units, whether or not such holders of Deferred Units are similarly situated; provided that such actions will be taken in a manner reasonably consistent with the terms of this Agreement.

4

(c)                                  Delegation by the Board. The Board in its sole discretion and on such terms and conditions as it may provide in accordance with the LLC Agreement may delegate all or any part of its authority and powers under this Agreement in accordance with the terms and conditions of the LLC Agreement.
