Exhibit g.2

AGREEMENT MADE THIS 13th day of November, 2007 by and between Nuveen Asset Management a Delaware corporation and a federally registered investment adviser (“Manager”), and Symphony Asset Management LLC, a California limited liability company and a federally registered investment adviser (“Sub-Adviser”).

WHEREAS, Manager serves as the investment manager for the Nuveen Senior Income Fund (the “Fund”), a closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) pursuant to an Investment Management Agreement between Manager and the Fund (as such agreement may be modified from time to time, the “Management Agreement”); and

WHEREAS, Manager desires to retain Sub-Adviser as its agent to furnish investment advisory services for the Fund, upon the terms and conditions hereafter set forth;

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the parties hereto agree as follows:

1. Appointment. Manager hereby appoints Sub-Adviser to provide certain sub-investment advisory services to the Fund for the period and on the terms set forth in this Agreement. Sub-Adviser accepts such appointments and agrees to furnish the services herein set forth for the compensation herein provided.

2. Services to be Performed. Subject always to the supervision of Fund’s Board of Trustees and the Manager, Sub-Adviser will furnish an investment program in respect of, make investment decisions for, and place all orders for the purchase and sale of securities for the Fund, all on behalf of the Fund. In the performance of its duties, Sub-Adviser will satisfy its fiduciary duties to the Fund, will monitor the Fund’s investments, and will comply with the provisions of Fund’s Declaration of Trust and By-laws, as amended from time to time, and the stated investment objectives, policies and restrictions of the Fund. Manager will provide Sub-Adviser with current copies of the Fund’s Declaration of Trust, By-laws, prospectus and any amendments thereto, and any objectives, policies or limitations not appearing therein as they may be relevant to Sub-Adviser’s performance under this Agreement. Sub-Adviser and Manager will each make its officers and employees available to the other from time to time at reasonable times to review investment policies of the Fund and to consult with each other regarding the investment affairs of the Fund. Sub-Adviser will report to the Board of Trustees and to Manager with respect to the implementation of such program.

Sub-Adviser is authorized to select the brokers or dealers that will execute the purchases and sales of portfolio securities for the Fund, and is directed to use its best efforts to obtain best execution, which includes most favorable net results and execution of the Fund’s orders, taking into account all appropriate factors, including price, dealer spread or commission, size and difficulty of the transaction and research or other services provided. It is understood that the

Sub-Adviser will not be deemed to have acted unlawfully, or to have breached a fiduciary duty to the Fund, or be in breach of any obligation owing to the Fund under this Agreement, or otherwise, solely by reason of its having caused the Fund to pay a member of a securities exchange, a broker or a dealer a commission for effecting a securities transaction for the Fund in excess of the amount of commission another member of an exchange, broker or dealer would have charged if the Sub-Adviser determined in good faith that the commission paid was reasonable in relation to the brokerage or research services provided by such member, broker or dealer, viewed in terms of that particular transaction or the Sub-Adviser’s overall responsibilities with respect to its accounts, including the Fund, as to which it exercises investment discretion. In addition, if in the judgment of the Sub-Adviser, the Fund would be benefited by supplemental services, the Sub-Adviser is authorized to pay spreads or commissions to brokers or dealers furnishing such services in excess of spreads or commissions which another broker or dealer may charge for the same transaction, provided that the Sub-Adviser determined in good faith that the commission or spread paid was reasonable in relation to the services provided. The Sub-Adviser will properly communicate to the officers and trustees of the Fund such information relating to transactions for the Fund as they may reasonably request. In no instance will portfolio securities be purchased from or sold to the Manager, Sub-Adviser or any affiliated person of either the Fund, Manager, or Sub-Adviser, except as may be permitted under the 1940 Act;

Sub-Adviser further agrees that it:

(a)

will use the same degree of skill and care in providing such services as it uses in providing services to fiduciary accounts for which it has investment responsibilities;

(b)

will conform to all applicable Rules and Regulations of the Securities and Exchange Commission in all material respects and in addition will conduct its activities under this Agreement in accordance with any applicable regulations of any governmental authority pertaining to its investment advisory activities;

(c)

will report regularly to Manager and to the Board of Trustees of the Fund and will make appropriate persons available for the purpose of reviewing with representatives of Manager and the Board of Trustees on a regular basis at reasonable times the management of the Fund, including, without limitation, review of the general investment strategies of the Fund, the performance of the Fund in relation to standard industry indices and general conditions affecting the marketplace and will provide various other reports from time to time as reasonably requested by Manager; and

(d)

will prepare such books and records with respect to the Fund’s securities transactions as requested by the Manager and will furnish Manager and Fund’s Board of Trustees such periodic and special reports as the Board or Manager may reasonably request.

3. Expenses. During the term of this Agreement, Sub-Adviser will pay all expenses incurred by it in connection with its activities under this Agreement other than the cost of securities (including brokerage commission, if any) purchased for the Fund.

4. Compensation. For the services provided and the expenses assumed pursuant to this Agreement, Manager will pay the Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation therefor, a portfolio management fee equal to the portion specified below of the investment management fee payable by the Fund to the Manager based on average daily net assets which includes net assets attributable to Fund Preferred Shares and the principal amount of borrowings pursuant to the Management Agreement, as the net amount of such fee is reduced by the obligation of Manager to reimburse certain fees and expenses to the Fund pursuant to an Expense Reimbursement Agreement of even date herewith by and between the Fund and the Manager, as such agreement may be modified from time to time:


Daily Net Assets	Percentage of Net Management Fee
Up to $125 million	50.0	%
$125 million to $150 million	47.5	%
$150 million to $175 million	45.0	%
$175 million to $200 million	42.5	%
$200 million and over	40.0	%

The portfolio management fee shall accrue on each calendar day, and shall be payable monthly on the first business day of the next succeeding calendar month. The daily fee accrual shall be computed by multiplying the fraction of one divided by the number of days in the calendar year by the applicable annual rate of fee, and multiplying this product by the net assets of the Fund, determined in the manner established by the Fund’s Board of Trustees, as of the close of business on the last preceding business day on which the Fund’s net asset value was determined.

For the month and year in which this Agreement becomes effective or terminates, there shall be an appropriate proration on the basis of the number of days that the Agreement is in effect during the month and year, respectively.

5. Services to Others. Manager understands, and has advised Fund’s Board of Trustees, that Sub-Adviser now acts, or may in the future act, as an investment adviser to fiduciary and other managed accounts, and as investment adviser or sub-investment adviser to one other investment company that is not a series of the Fund, provided that whenever the Fund and one or more other investment advisory clients of Sub-Adviser have available funds for investment, investments suitable and appropriate for each will be allocated in a manner believed by Sub-Adviser to be equitable to each. Manager recognizes, and has advised Fund’s Board of Trustees, that in some cases this procedure may adversely affect the size of the position that the Fund may obtain in a particular security. It is further agreed that, on occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interests of the Fund as well as other accounts, it may, to the extent permitted by applicable law, but will not be obligated to, aggregate

the securities to be so sold or purchased for the Fund with those to be sold or purchased for other accounts in order to obtain favorable execution and lower brokerage commissions. In addition, Manager understands, and has advised Fund’s Board of Trustees, that the persons employed by Sub-Adviser to assist in Sub-Adviser’s duties under this Agreement will not devote their full such efforts and service to the Fund. It is also agreed that the Sub-Adviser may use any supplemental research obtained for the benefit of the Fund in providing investment advice to its other investment advisory accounts or for managing its own accounts.

6. Limitation of Liability. Manager will not take any action against Sub-Adviser to hold Sub-Adviser liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the performance of Sub-Adviser’s duties under this Agreement, except for a loss resulting from Sub-Adviser’s willful misfeasance, bad faith, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

7. Term; Termination; Amendment. This Agreement shall become effective with respect to the Fund on the same date as the Management Agreement between the Fund and the Manager becomes effective, provided that it has been approved by a vote of a majority of the outstanding voting securities of the Fund in accordance with the requirements of the 1940 Act, and shall remain in full force until August 1, 2008 unless sooner terminated as hereinafter provided. This Agreement shall continue in force from year to year thereafter with respect to the Fund, but only as long as such continuance is specifically approved for the Fund at least annually in the manner required by the 1940 Act and the rules and regulations thereunder; provided, however, that if the continuation of this Agreement is not approved for the Fund, the Sub-Adviser may continue to serve in such capacity for the Fund in the manner and to the extent permitted by the 1940 Act and the rules and regulations thereunder.

This Agreement shall automatically terminate in the event of its assignment and may be terminated at any time without the payment of any penalty by the Manager on sixty (60) days’ written notice to the Sub-Adviser. This Agreement may be terminated by the Sub-Adviser as of July 31 of any year after 2007 without payment of any penalty upon sixty (60) days’ prior written notice to the Manager. This Agreement may also be terminated by the Fund with respect to the Fund by action of the Board of Trustees or by a vote of a majority of the outstanding voting securities of such Fund on sixty (60) days’ written notice to the Sub-Adviser by the Fund.

This Agreement may be terminated with respect to the Fund at any time without the payment of any penalty by the Manager, the Board of Trustees or by vote of a majority of the outstanding voting securities of the Fund in the event that it shall have been established by a court of competent jurisdiction that the Sub-Adviser or any officer or director of the Sub-Adviser has taken any action which results in a breach of the covenants of the Sub-Adviser set forth herein.

The terms “assignment” and “vote of a majority of the outstanding voting securities” shall have the meanings set forth in the 1940 Act and the rules and regulations thereunder.

Termination of this Agreement shall not affect the right of the Sub-Adviser to receive payments on any unpaid balance of the compensation described in Section 4 earned prior to such termination. This Agreement shall automatically terminate in the event the Investment Management Agreement between the Manager and the Fund is terminated, assigned or not renewed.
