1. Fund Reporting. The Fund shall submit an Order Flow Report to ReFlow, no later than the Morning Deadline each Business Day. ReFlow may, in its sole discretion, extend this deadline past the Morning Deadline (but by no more than one hour beyond the Morning Deadline), provided that ReFlow provides notice of the changed deadline on its website prior to Market Close on the next Business Day. The Fund shall submit its Order Flow Report on ReFlow's website, or if such website is not available, through such other methods as ReFlow may specify.

- 2 -

2. Auction Amount. On each Business Day that ReFlow conducts an Auction, ReFlow shall establish an Initial Auction Amount, equal to the amount of cash it will make available that day to purchase shares of Participating Funds. The Initial Auction Amount, plus any cash received from Automatic Redemptions (as defined below in Section II.5) and Voluntary Redemptions equal the Final Auction Amount.
3. Auction Bids. Prior to Market Close on each Business Day that ReFlow conducts an Auction, ReFlow may establish a Minimum Fee Bid, below which no Fee Bid will be accepted. Any Minimum Fee Bid will be posted on ReFlow's website. If the Fund desires to participate in a particular Auction, the Fund shall submit a bid to ReFlow, consisting of (a) the amount of liquidity the Fund desires, either in the form of a Cash Bid or Standing Bid; and (b) the Fund's Fee Bid. The Fund's submission may be placed, and may be modified or cancelled, by the Fund at any time up until the Market Close. A Cash Bid shall be effective for only one Auction. A Standing Bid shall remain in continuous effect from day to day unless modified or cancelled by the Fund.
4. Fee Bid Calculations. If the Fund places a Standing Bid, the Auction Program shall calculate the dollar amount of the Fund's bid based on its net redemptions reported. If the Fund places a Cash Bid but thereafter reports net redemptions of less than that amount, the Fund's bid shall be the amount of its net redemptions.
5. Automatic Redemptions. If the Fund reports net inflows in its Order Flow Report and ReFlow holds Shares of the Fund, ReFlow shall automatically redeem an amount of Shares equal to the lesser of (a) the net number of shares sold as reported in the Order Flow Report; or (b) the number of shares owned by ReFlow. ReFlow may, in its sole discretion, adopt additional automatic redemption policies, pursuant to which ReFlow shall redeem shares, regardless of whether a Participating Fund remains in a state of net redemptions. Any such policy shall be disclosed on ReFlow's website. Any policy shall apply uniformly to all Participating Funds, and any change to a policy shall apply only in respect of shares of the Fund purchased after such policy is disclosed. The Fund shall effect all automatic redemption orders at the NAV of the Fund calculated at Market Close that day. Any cash to be received by ReFlow from automatic redemptions will be added to the Final Auction Amount. ReFlow reserves the right to cancel automatic redemptions at any time prior to Market Close on any Business Day, provided that it provides notice of the cancellation on its website or through alternative means specified by ReFlow.
6. Auction Calculations. After all Participating Funds have submitted their Order Flow Reports, ReFlow shall conduct the Auction. The Winning Fee Rate shall be the lowest fee rate bid at which the entire Final Auction Amount can be invested. If the Fund's Fee Bid is equal to or greater than the Winning Fee Rate, the Fund shall be a Winning Fund. If the Fund is a Winning Fund, ReFlow shall purchase an amount of Shares equal to the dollar amount of the Fund's bid if there is sufficient cash available from the Final Auction Amount after purchasing shares of other Winning

- 3 -

Funds who submitted higher Fee Bids than the Fund. If there is insufficient cash in the Final Auction Amount to purchase an amount of Shares equal to the Fund's bid, ReFlow shall purchase an amount of Shares up to the amount of cash remaining in the Final Auction Amount, provided, however, that if the Fund submits the same Fee Bid as another Winning Fund(s), ReFlow shall purchase shares from the Fund and such other Winning Fund(s) on a pro rata basis.

7. Automatic Purchases. If the Fund is a Winning Fund, the Auction Program shall automatically issue a purchase order to the Fund, which the Fund shall effect at its NAV determined at the Market Close that day. ReFlow shall have no discretion in purchasing Shares as determined by the automated Auction process.
8. Auction Results. The results of each Auction shall be disclosed to each Participating Fund on ReFlow's website.
9. Error Corrections. If the Fund has reported an error in its Order Flow Report, it must be reported to ReFlow immediately after the Fund discovers the error. If the error is discovered prior to the Auction, the Fund shall amend its Order Flow Report to reflect the corrected information. If the error is discovered after the Auction has been held, the Fund shall submit the corrected information as soon as possible thereafter. If the Fund was a Winning Fund in the Auction, and experienced more net redemptions than previously reported, ReFlow shall issue another purchase order to the Fund for Shares in the amount of the error, which the Fund agrees to accept, at the Winning Fee Rate determined in the Auction, up to the amount of the cash available as determined by ReFlow, subject to an overall limit of share purchases by ReFlow that do not exceed the Final Auction Amount. If the Fund was a Winning Fund in the Auction, and experienced less net redemptions than previously reported, ReFlow shall issue a redemption order to the Fund for the amount of the error. If ReFlow owned shares of the Fund, and the Fund experienced more net sales than previously reported, ReFlow shall issue an additional redemption order to the Fund equal to the lesser of (a) the amount of the error, or (b) the amount of Shares held by ReFlow.
10. Late Reports. The Fund shall submit its Order Flow Report to ReFlow no later than the Morning Deadline each Business Day but subject to change (or later as provided in Section II.1). If the Fund does not submit its Order Flow Report by such time, the Auction shall commence and the Fund's Auction Bid shall not be included in calculating the Auction results. If the Fund's Order Flow Report is submitted after the Auction, ReFlow shall take the following actions:

1. If the Fund reports net redemptions, and the Fund's Fee Bid was equal to or greater than the Winning Fee Bid, ReFlow shall issue a purchase order to the Fund for Shares in the amount of net redemptions reported, which the Fund agrees to accept, at the Winning Fee Rate determined in the Auction, up to the amount of the cash available as determined by ReFlow, subject to an overall limit of share purchases by ReFlow that do not exceed the Final Auction Amount.

- 4 -

2. If ReFlow owned shares of the Fund, and the Fund reports net sales, ReFlow shall issue a redemption order to the Fund equal to the lesser of (i) the amount of the sales, or (ii) the amount of Shares held by ReFlow.

11. Transactions Effected Pursuant to Error Corrections and Late Reports. ReFlow shall purchase shares of Participating Funds based on error corrections and late reports on a first come, first served basis, until the cash available as determined by ReFlow runs out, up until Market Close that day. Purchase and redemption orders from ReFlow resulting from error corrections and late reports shall occur automatically, and the Fund shall effect such transactions at the NAV of the Fund determined at the Market Close that day.
12. Fee Payment. If the Fund is a Winning Fund in an Auction, the Fund shall pay to ReFlow the Auction Program Fee, which shall equal to the Fund's Fee Bid multiplied by the aggregate dollar amount of Shares purchased in the Auction.
13. Auction Cancellation. ReFlow reserves the right to not hold an Auction on any Business Day, or to cancel an Auction at any time prior to Market Close. After Market Close, ReFlow shall not cancel an Auction unless extraordinary conditions of force majeure make it impossible for ReFlow to conduct the Auction. ReFlow shall provide notice of any cancellation to all Participating Funds on the ReFlow website, or if such website is not available, through such other methods as ReFlow may specify.
14. Voluntary Redemptions. At any time that ReFlow holds Shares, the Fund may request that ReFlow voluntarily submit a redemption request to the Fund for some or all of such Shares. Any such request must be received by ReFlow prior to Market Close. ReFlow shall determine in its sole discretion whether it wishes to honor the request and submit a redemption request to the Fund.
15. Limits on Purchases of Fund Shares. ReFlow shall not purchase more than the lesser of (a) 3% of the outstanding voting Shares of the Fund or (b) the number of Shares that can be purchased subject to the capital or other limits announced from time to time by ReFlow.
16. Non-acceptance of Bids. Notwithstanding any other provision of this Agreement, ReFlow shall not be required to accept any Auction Bid (and may rescind any such Auction Bid after acceptance) that is made by the Fund in violation of any provision of this Agreement, provided that ReFlow has given the Fund notice of such violation.
