ITEM 1:  Summary Term Sheet

         The Topiary Fund for Benefit Plan Investors (BPI) LLC, a closed-end,
non-diversified, management investment company organized as a Delaware limited
liability company (the "Fund"), is offering to repurchase limited liability
company interests (the "Interests") in the Fund from members of the Fund
("Members"). Subject to the conditions set forth in the Offer to Repurchase
document and related Letter of Transmittal (attached as Exhibit (a)(1)(ii) and
Exhibit (a)(1)(iii), respectively), the Fund will repurchase up to $10,287,921
(approximately 15% of the net asset value of the Master Fund estimated as of
August 31, 2005) of limited liability company Interests that are tendered by
Members and not withdrawn prior to 12:00 midnight, Eastern Time, on October
27, 2005, subject to any extensions of the offer to repurchase Interests
("Repurchase Offer").

         Members may tender all or a portion of their Interests in the Fund
(defined as a specific dollar value) up to an amount such that they maintain
the minimum required capital account balance of $25,000 after the repurchase
of Interests. If a Member tenders a portion of its Interests, the Fund
reserves the right to repurchase less than the amount a Member tenders if the
repurchase would cause the Member's capital account to have less than the
required minimum balance of $25,000. If the Fund accepts the tender of all or
a portion of a Member's Interests, the Fund intends to make payment for the
Interests it repurchases from one or more of the following sources: cash on
hand, proceeds from the Master Fund's redemption of interests in the
Investment Funds (as defined below), or borrowings. None of the Fund, the
Master Fund, DB Investment Managers, Inc., the investment adviser of the Fund
("Adviser"), or directors of the Fund ("Directors") has decided at this time
to borrow funds to repurchase Interests in connection with the Repurchase
Offer. However, depending on the dollar amount of Interests tendered and
prevailing general economic and market conditions, the Fund, in its sole
discretion, may decide to borrow money to fund all or a portion of the
repurchase price.

         The amount due to any Member who tenders all of its Interests in the
Fund (and which are all accepted for repurchase by the Fund) will be equal to
the value of that Member's capital account based on the Fund's net asset value
as of December 31, 2005 or, if the Repurchase Offer is extended, as of a date
designated by the Fund in an amended notice to Members (the "Full Repurchase
Valuation Date"), after giving effect to all allocations, including, but not
limited to, withholding tax, to be made to the Member's capital account as of
such date. The Fund reserves the right to adjust the Full Repurchase Valuation
Date to correspond with any extension of the Repurchase Offer.

         The Fund invests substantially all of its assets in The Topiary
Offshore Fund for Benefit Plan Investors (BPI) LDC, a Cayman Islands limited
duration company (the "Offshore Fund"), which in turn invests substantially
all of its assets in The Topiary Master Fund for Benefit Plan Investors (BPI)
LLC (the "Master Fund"), a separate closed-end, non-diversified, management
investment company with the same investment objectives as the Fund and the
Offshore Fund. This structure is sometimes called a "master/feeder" structure.
The Fund has been advised by the Master Fund that the Master Fund is making a
concurrent tender offer to the Offshore Fund to repurchase interests in the
Master Fund at least equivalent in value to the value of the Interests that
the Fund is offering to repurchase. The Offshore Fund will then distribute the
proceeds of such repurchases to the Fund. The Fund cannot make a repurchase
offer larger than the repurchase offer made by the Master Fund.

         The Fund's net asset value as of December 31, 2005 will be based in
part on oral or written estimates of the value of the Master Fund's
investments in the private funds in which the Master Fund invests ("Investment
Funds"). Therefore, repurchase payments to Members who tender all of their
Interests in the Fund may not reflect final net asset values for the Full
Repurchase Valuation Date calculated by the Investment Funds; however, the
Fund will generally not make any adjustments for final valuations from the
Master Fund based on adjustments received from the Investment Funds, and the
withdrawing Member (if such valuations are adjusted upwards) or the remaining
Members (if such valuations are adjusted downwards) will bear the risk of
change of any such valuations.

         The Repurchase Offer remains open to Members until 12:00 midnight,
Eastern Time, Thursday, October 27, 2005, or, if the Repurchase Offer is
extended, such time and date as the Fund designates in an amended notice to
Members ("Repurchase Request Deadline"). Until that time, Members have the
right to change their minds and withdraw the tenders of their Interests in the
Fund. Withdrawn Interests may be re-tendered, however, provided that such
tenders are made before the Repurchase Request Deadline by following the
tender procedures described herein. Members who tender Interests may bear a
share of any withdrawal charge imposed on the Master Fund by any Investment
Fund from which the Master Fund withdraws in order to meet tender requests.




         If a Member would like the Fund to repurchase all or a portion of the
Member's Interests, the Member should complete, sign and either (i) mail (via
certified mail return receipt requested) or otherwise deliver a Letter of
Transmittal, attached to this document as Exhibit (a)(1)(iii), to PFPC Inc.,
P.O. Box 219, Claymont, Delaware 19703, attention: The Topiary Fund for
Benefit Plan Investors (BPI) LLC, or (ii) fax it to the Adviser, c/o of PFPC
Inc. at (302) 791-2790, so that it is received before 12:00 midnight, Eastern
Time, on Thursday, October 27, 2005. If the Member chooses to fax the Letter
of Transmittal, it should mail the original Letter of Transmittal to PFPC Inc.
promptly after it is faxed (although the original does not have to be received
before 12:00 midnight, Eastern Time, on Thursday, October 27, 2005). Of
course, the net asset value of the Interests in the Fund will change between
August 31, 2005 (the last time prior to the date of this filing as of which
the Fund's net asset value has been calculated), and December 31, 2005, the
date as of which the value of Interests in the Fund will be determined for
purposes of calculating the repurchase price paid to Members who have tendered
all of their Interests in the Fund (and which have all been accepted for
repurchase by the Fund). Members may obtain the net asset value of the Fund
and their Interests, which the Fund calculates monthly based on the
information the Master Fund receives from the investment advisers of the
Investment Funds, by contacting the Adviser, c/o PFPC Inc., at (302) 791-2810
or at the address listed above, Monday through Friday, except holidays, during
normal business hours of 9:00 a.m. to 5:00 p.m. (Eastern Time).

         Please note that just as each Member has the right to withdraw the
tender of Interests in the Fund, the Fund has the right to cancel, amend,
suspend or postpone this Repurchase Offer at any time before 12:00 midnight,
Eastern Time, on Thursday, October 27, 2005. Also realize that although the
Repurchase Offer expires on October 27, 2005, a Member that tenders all of its
Interests in the Fund (and which are all accepted for repurchase by the Fund)
will remain a Member through December 31, 2005, when the value of that
Member's Interests is determined.

         Within five days of the Repurchase Request Deadline, or no later than
November 3, 2005, each Member whose Interests in the Fund or portion thereof
have been accepted for repurchase will be given a non-interest bearing,
non-transferable promissory note by the Fund entitling the Member to be paid
an amount equal to 100% of the unaudited net asset value of such Member's
capital account (or portion thereof) being repurchased. In the case of both a
full or partial tenders of Interests, the note will entitle the Member to be
paid within thirty (30) days after the Full Repurchase Valuation Date or, if
the Master Fund has requested withdrawals of its capital from any Investment
Funds in order to fund the repurchase of Interests, ten business days after
the Master Fund has received at least 90% of the aggregate amount withdrawn by
the Master Fund from such Investment Funds, whichever is the later (either
such date, a "Payment Date").

contained in a pre-effective amendment to the Fund's registration statement on
Form N-2, as filed with the SEC via EDGAR on September 14, 2004, and as
disclosed in the Fund's prospectus dated September 14, 2004 (the

whether the Fund will repurchase Interests from Members from time to time
pursuant to written tenders. The Board of Directors expects that, subsequent
to this offer to repurchase Interests from Members as of December 31, 2005,
the Fund will offer to repurchase Interests as of the last business day of

terms of the LLC Agreement, to tender all of such Member's Interests for
repurchase by the Fund has not been given the opportunity to so tender within
a period of two years after the request (whether in a single repurchase offer
