CAPITAL SUPPORT AGREEMENT

Exhibit 10.1

CAPITAL SUPPORT AGREEMENT

THIS CAPITAL SUPPORT AGREEMENT (this “Agreement”) is made as of the 8th day of November, 2007, by and between SEI Investments Company (the “Support Provider”) and SEI Daily Income Trust Prime Obligation Fund (the “Fund”).

WITNESSETH:

WHEREAS, the Fund is an investment company registered with the Securities and Exchange Commission in accordance with the Investment Company Act of 1940 (as amended, the “1940 Act”);

WHEREAS, the Fund is a money market fund that seeks to maintain a stable net asset value of $1.00 per share using the Amortized Cost Method as defined in and in accordance with Rule 2a-7 promulgated under the 1940 Act (as amended, “Rule 2a-7”);

WHEREAS, the Fund holds notes and other instruments (the “Notes”) issued by Cheyne Finance LLC and other structured investment vehicles shown on Schedule A attached hereto (each, an “Issuer”);

WHEREAS, Rule 2a-7(c)(6)(ii) requires a money market fund to “dispose of [a portfolio] security as soon as practicable consistent with achieving an orderly disposition of the security, …, absent a finding by the board of directors that disposal of the portfolio security would not be in the best interests of the money market fund (which determination may take into account, among other factors, market conditions that could affect the orderly disposition of the portfolio security)” upon the occurrence of certain events;

WHEREAS, one or more of the events specified in Rule 2a-7(c)(6)(ii) have occurred with respect to certain of the Notes;

WHEREAS, a sale of the Notes under current market conditions is unlikely to result in the full recovery of the Fund’s investments, and may cause the Fund to realize losses to the extent that it could no longer maintain a stable net asset value of $1.00 per share;

WHEREAS, the Fund’s failure to maintain a stable net asset value of $1.00 per share could adversely affect the Support Provider’s proprietary mutual fund business, which would reduce the profits derived by the Support Provider from this line of business and potentially injure the Support Provider’s goodwill and reputation; and

WHEREAS, the Board of Trustees of the Fund (each a “Board”) will consider this Agreement in determining whether disposal of the Notes currently would be in the best interest of the Fund:

NOW, THEREFORE, in consideration of the above premises, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Support Provider hereby agrees as follows:

1. Definitions. In addition to the terms defined elsewhere in this Agreement, the following terms have the meanings indicated:

(a) “Amortized Cost Value” means, with respect to any Eligible Note held by the Fund, the value of that Eligible Note as determined using the Amortized Cost Method in accordance with Rule 2a-7 on the relevant date.

(b) “Capital Contribution” means a cash contribution by the Support Provider to the Fund for which the Support Provider does not receive any shares or other consideration from the Fund.

(c) “Contribution Event” means, with respect to any Eligible Note held by any Fund, any of the following occurrences:

The excess of the Amortized Cost Value of the Eligible Notes subject to a Contribution Event over the amount received by the Fund in connection with such Contribution Event shall constitute the “Loss” on such Eligible Notes.

(d) “Eligible Notes” means the Notes held by the Fund as portfolio securities on the date hereof or any Replacement Notes other than Qualifying New Securities.

(e) “Letter of Credit” means one or more letters of credit issued by the Letter of Credit Provider for the benefit of the Fund in an aggregate amount equal to $126,000,000, and which shall terminate no sooner than the date set forth in Section 3(c)(iv) of this Agreement.

(f) “Letter of Credit Provider” means JP Morgan Chase Bank, NA., or any substitute provider whose obligations are rated as First Tier Securities as defined in paragraph (a)(12) of Rule 2a-7.

(g) “Maximum Contribution Amount” means one hundred twenty six million dollars ($126,000,000).

(h) “Minimum Permissible NAV” means $0.9975 for so long as the Fund is rated by Standard & Poor’s, and $0.995 if the Fund is not rated by Standard & Poor’s.

(i) “NAV Deviation” means the deviation, if any, of the Fund’s current net asset value per share calculated using available market quotations (or an appropriate substitute that reflects current market conditions) below the Fund’s price per share for purposes of distribution, redemption and repurchase of its shares calculated using the Amortized Cost Method. The NAV Deviation shall be calculated in accordance with procedures adopted by the Fund’s Board in compliance with Rule 2a-7(c)(7)(ii)(A), except that, for purposes of calculating the Required Contribution Amount, it shall exclude any account receivable or other asset representing the Support Provider’s obligations under this Agreement.

(j) “Permissible NAV Deviation” means $0.0025 for so long as the Fund is rated by Standard & Poor’s, and $0.005 if the Fund is not rated by Standard & Poor’s.

-2-

(k) “Qualifying New Securities” means any Notes or Replacement Notes which are or become “Eligible Securities,” as defined in paragraph (a)(10) of Rule 2a-7.

(l) “Replacement Notes” means any securities or other instruments received in exchange for, or as a replacement of, the Notes as a result an exchange offer, debt restructuring, reorganization or similar transaction pursuant to which the Notes are exchanged for, or replaced with, new securities of the Issuer or a third party.

(m) “Required Contribution Amount” means for the Fund on the date of any Contribution Event: (i) if the Fund’s NAV Deviation, after giving effect to any Contribution Events and all payments received by the Fund in respect of the Eligible Notes, exceeds the Permissible NAV Deviation, a Capital Contribution in an amount sufficient to reduce the Fund’s NAV Deviation to such Permissible NAV Deviation after giving effect to such Capital Contribution, or (ii), in any other event, zero. The Required Contribution Amount is intended to enable the Fund to maintain its net asset value per share at no less than the Minimum Permissible NAV.

2. Covenants of the Fund. The Fund agrees that:

(a) To the extent consistent with the Fund’s interest, the Board shall consult with the Support Provider with respect to all decisions regarding each Eligible Note (including, but not limited to, any decision to sell the Eligible Note or to forgo the right to any payment) prior to the occurrence of a Contribution Event with respect to that Eligible Note. Nothing in this Agreement shall be construed to cause the delegation by the Board to any person any authority which is not permitted to be delegated under Rule 2a-7.

(b) The Fund will retain any Capital Contribution and not include the Capital Contribution in any dividend or other distribution to the Fund’s shareholders. For the avoidance of doubt, for purposes of this subparagraph, the redemption of the Fund’s shares shall not constitute a “distribution” to shareholders.

(c) The Fund will sell the Eligible Notes (i) promptly following any change in the Letter of Credit Provider’s short term credit ratings such that the Letter of Credit Provider’s obligations no longer qualify as First Tier Securities as defined in paragraph (a)(12) of Rule 2a-7, or (ii) on the business day immediately prior to the date set forth in subparagraph 3(c)(iv); provided that, the Fund shall not be required to complete any such sale if the amount the Fund expects to receive would not result in the payment of a Capital Contribution, or, with respect to an event described in 2(c)(i) above, if the Support Provider substitutes an obligation or credit support that satisfies the requirement of a First Tier Security within fifteen (15) calendar days from the occurrence of such event and, during such 15 day period, the Letter of Credit Provider’s obligations continue to qualify as Second Tier Securities under paragraph (a)(22) of Rule 2a-7.

3. Contributions to Fund.

(a) If a Contribution Event occurs prior to the occurrence of a Termination Event, the Support Provider will make a Capital Contribution in an amount equal to the least of (i) the Loss incurred as a result of such Contribution Event, (ii) the Required Contribution Amount, or (iii) the Maximum Contribution Amount reduced by the amount of any Capital Contribution previously made by the Support Provider to the Fund.

-3-

(b) The Support Provider shall make the Capital Contribution to the Fund not later than one business day after the occurrence of a Contribution Event, by 12:00 noon, Eastern Time. Each Capital Contribution made hereunder shall be made in immediately available funds, without deduction, set-off or counterclaim, to the Fund. In the event that the Support Provider does not make a Capital Contribution when due, the Fund will draw upon the Letter of Credit by 4:00 p.m. on the day that such Capital Contribution was required to have been made in an amount equal to the Capital Contribution that is due, and any amount received under such Letter of Credit shall be deemed to be a Capital Contribution made hereunder by the Support Provider.

(c) The obligation of the Support Provider to make Capital Contributions pursuant to this Agreement shall terminate upon the earliest to occur of (such occurrence, the “Termination Event”) (i) the repayment in full, in cash, of all Eligible Notes, (ii) the Support Provider having made Capital Contributions equal to the Maximum Contribution Amount, (iii) the receipt of Replacement Notes for all of the Notes that are, or become, Qualifying New Securities, and (iv) 5:00 p.m. Eastern Time on November 6, 2008. Upon the occurrence of a Termination Event, the Fund shall surrender the Letter of Credit for cancellation.

4. Reliance by the Fund and the Board. The Support Provider acknowledges and consents to:

(a) The Board’s reliance on the Support Provider’s obligations under this Agreement in making any determination required under Rule 2a-7; and

(b) For purposes of calculating the Fund’s NAV Deviation, the inclusion of the Capital Contribution that would be payable to the Fund under this Agreement if all of the Eligible Notes were sold on the date of such calculation for the market value used to calculate such NAV Deviation; and

(c) The inclusion of such amount in the Fund’s audited or unaudited financial statements, to the extent required by generally accepted accounting principles.

5. Representations and Warranties. The Support Provider hereby represents and warrants that:

(a) It is duly organized and validly existing under the laws of the jurisdiction of its organization or incorporation and, if relevant under such laws, in good standing;

(b) It has the power to execute this Agreement, to deliver this Agreement and to perform its obligations under this Agreement and has taken all necessary action to authorize such execution, delivery and performance;

6. General.

(a) The Fund may not assign its rights under this Agreement to any person or entity, in whole or in part, without the prior written consent of the Support Provider.

(b) No waiver of any provision hereof or of any right or remedy hereunder shall be effective unless in writing and signed by the party against whom such waiver is sought to be enforced. No delay in exercising, no course of dealing with respect to or no partial exercise of any right or remedy hereunder shall constitute a waiver of any other right or remedy, or future exercise thereof.

(c) If any provision of this Agreement is determined to be invalid under any applicable statute or rule of law, it is to that extent to be deemed omitted, and the balance of the Agreement shall remain enforceable.

(d) Subject to the next sentence, all notices shall be in writing and shall be deemed to be delivered when received by certified mail, postage prepaid, return receipt requested, or when sent by facsimile or e-mail confirmed by call back.

(h) This Agreement is solely for the benefit of the Fund, and no other person shall acquire or have any rights under or by virtue of this Agreement.

(i) This Agreement shall terminate upon the occurrence of any change in the Letter of Credit Provider’s short-term credit ratings such that the Letter of Credit Provider’s obligations no longer qualify as First Tier Securities as defined in paragraph (a)(12) of Rule 2a-7, unless the Support Provider satisfies the terms of paragraph 2(c) of this Agreement relating to arrangements for a substitute obligation or credit support. Termination under this Section 6(i) shall not relieve (i) the Funds of their obligation to sell the Eligible Notes, to the extent that such a sale is required by Section 2(c) of this Agreement; or (ii) the Support Provider of its obligation to make a Capital Contribution to the Fund following such a sale, to the extent that such sale would give rise to a Contribution Event.
