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
$10,142,360.05 (approximately 15% of the net asset value of the Master Fund
estimated as of February 28, 2006) of limited liability company Interests that
are tendered by Members and not withdrawn prior to 12:00 midnight, Eastern
Time, on April 26, 2006, 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 June 30, 2006 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 June 30, 2006 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, Wednesday, April 26, 2006, 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 Wednesday, April 26, 2006. 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 Wednesday, April 26, 2006). Of course,
the net asset value of the Interests in the Fund will change between February
28, 2006 (the last time prior to the date of this filing as of which the
Fund's net asset value has been calculated), and June 30, 2006, 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 Wednesday, April 26, 2006. Also realize that although the Repurchase
Offer expires on April 26, 2006, 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 June 30, 2006, when the value of that Member's Interests is
determined.

     Within five days of the Repurchase Request Deadline, or no later than May
2, 2006, 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").

will repurchase Interests from Members twice a year, as of the last business
day of June and December. Neither the Fund nor the Master Fund is aware of any

repurchase by the Fund has not been given the opportunity to so tender within

Dear Investor in
The Topiary Fund for Benefit Plan Investors (BPI) LLC:

repurchase offer relating to The Topiary Fund for Benefit Plan Investors (BPI)
LLC (the "Fund"). If you are not interested in selling all or a portion of
your limited liability company interests in the Fund ("Interests") at this
time, please disregard this notice and take no action.

          The repurchase offer period will begin on March 22, 2006 and end on
April 26, 2006 (the "Repurchase Request Deadline"). For Members tendering all
of their Interests in the Fund (and which are all accepted for repurchase by
the Fund), the value of their Interests for purposes of calculating repurchase
price will be determined as of June 30, 2006 (the "Full Repurchase Valuation
Date"). Members tendering Interests for repurchase will be given a promissory
note no later than May 2, 2006 entitling them to payment for their tendered
Interests. For both Members making full or partial tenders of their Interests,
payment will either be made within thirty (30) days of the Full Repurchase
Valuation Date, or ten business days after The Topiary Master Fund for Benefit

     hold Interests in the Fund. 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 repurchase of Interests pursuant to the Repurchase Offer will have
     the effect of decreasing the net assets of the Fund and increasing the
     proportionate interest in the Fund of Members who do not tender
     Interests. A reduction in the net assets of the Fund could limit the
     Master Fund's, and in turn the Fund's, access to certain investment
     opportunities, cause the Fund, through the Master Fund, to sell assets it
     would not have sold otherwise (including public securities), or result in
     Members who do not tender Interests bearing higher costs to the extent
     that certain expenses borne by the Fund are relatively fixed and may not
     decrease if assets decline.

o    WHAT ARE THE TERMS OF THE REPURCHASE OFFER? We will repurchase up to
     $10,142,360.05 (approximately 15% of the net asset value of the Master
     Fund estimated as of February 28, 2006) of limited liability company
     interests. If the offer is oversubscribed, we may repurchase, in our sole
     discretion, all or only a pro-rata portion of the Interests you tender.
     This offer will remain open until 12:00 midnight, Eastern Time,
     Wednesday, April 26, 2006, or, if the Repurchase Offer is extended, such
     time and date as the Fund designates in an amended notice to Members
     ("Repurchase Request Deadline"). For a Member who tenders all of its
     Interests in the Fund (and which are all accepted for repurchase by the
     Fund), Interests will be valued for the purposes of determining their
     repurchase price as of June 30, 2006 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"). Such Member will receive
     the net asset value of its capital account determined as of the Full
     Repurchase Valuation Date and based on the net asset value of the Fund's
     assets (based on oral or written estimates of the value of the Master
     Fund's investments).

     You must determine whether to tender all or a portion of your Interests
     prior to the Repurchase Request Deadline but, if you are tendering all of
     your Interests in the Fund (and if all are accepted for repurchase by the
     Fund), the net asset value at which the Fund will repurchase your
     Interests will not be determined until the Full Repurchase Valuation
     Date. The net asset value of the Fund can fluctuate and may fluctuate
     between the date you submit your repurchase request and the Repurchase
     Request Deadline and the Full Repurchase Valuation Date. The net asset
     value of the Fund on the Repurchase Request Deadline and the Full
     Repurchase Valuation Date could be higher or lower than on the date you
     submit a Repurchase Request.



     If you would like to obtain the most recently calculated net asset value
     of the Fund or your Interests, you may contact PFPC Inc., at the phone
     number or address listed above, Monday through Friday, except holidays,
     during normal business hours of 9:00 a.m. to 5:00 p.m. (Eastern Time).

     Members who tender Interests may bear a share of any withdrawal charge
     imposed on the Fund by any Investment Fund from which the Fund, through
     the Master Fund, withdraws in order to meet tender requests.

o    WHAT IS THE AMOUNT OF EACH MEMBER'S TENDER? If you tender a portion of
     your Interests in the Fund, you must leave an amount equal to at least
     $25,000 (the "Required Minimum Balance") in the Fund. The Fund reserves
     the right to reduce the amount of Interests repurchased from you so that
     the Required Minimum Balance is maintained.

o    WHAT IS THE PROCEDURE FOR TENDERS? If you would like us to repurchase all
     or a portion of your Interests in the Fund, you should mail or fax a
     Letter of Transmittal, enclosed with our offer, to PFPC Inc. at the
     address/fax number listed on page 2 of this Offer to Repurchase, so that
     it is received before 12:00 midnight, April 26, 2006. If you choose to
     fax the Letter of Transmittal, you should mail the original Letter of
     Transmittal to PFPC Inc. promptly after you fax it (although the original
     does not have to be received before 12:00 midnight, April 26, 2006). Of
     course, the net asset value of Interests in the Fund is likely to change
     between February 28, 2006 (the last time the Fund's net asset value was
     calculated), March 31, 2006 (the next time it will be calculated), and
     June 30, 2006, when the net asset value of the capital accounts of
     Members tendering all of their Interests in the Fund (and which are all
     accepted for repurchase by the Fund) will be determined for purposes of
     calculating the repurchase price of such Members' Interests. Generally,
     the net asset value of the Fund is determined monthly.

     If you elect to tender, it is your responsibility to confirm receipt of
     the Letter of Transmittal with PFPC Inc. To assure good delivery, please
     send the Letter of Transmittal to PFPC Inc. and not to your financial
     advisor.

o    DO MEMBERS HAVE ANY WITHDRAWAL RIGHTS? Following this summary is a formal
     notice of our offer to repurchase your Interests in the Fund. Our offer
     remains open to you until 12:00 midnight on April 26, 2006. Until this
     time, you have the right to change your mind and withdraw your Interests
     from consideration for repurchase. 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.

o    WHEN WILL PAYMENT BE MADE TO MEMBERS? Within five days of the Repurchase
     Request Date, or no later than May 2, 2006, each Member whose Interests
     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. For both a Member making full or partial tenders of
     its 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 the private investment
     funds in which the Master Fund invests ("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"). We will pay you from one or more of the
     following sources: cash on hand, proceeds from the redemption of
     interests in the Investment Funds, or borrowings. Payment may be delayed
     if it is determined that the Master Fund redeem its interests in
     Investment Funds to make such payments, but has experienced unusual
     delays in receiving payments from the Investment Funds. None of the Fund,
     the Master Fund, the Adviser or Directors has determined 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.


                                      2


o    WHAT ARE THE MOST SIGNIFICANT CONDITIONS OF THE REPURCHASE OFFER? Please
     note that just as you have the right to withdraw your Interests, we have
     the right to cancel, amend, suspend or postpone this offer at any time
     before 12:00 midnight, April 26, 2006. Also realize that although the
     tender offer expires on 12:00 midnight, April 26, 2006, if you tender all
     of your Interests (and if all are accepted for repurchase by the Fund),
     you remain an investor in the Fund until June 30, 2006 when the net asset
     value of your Interests is calculated for purposes of determining their
     repurchase price.

o    BACKGROUND INFORMATION ABOUT THE FUND. The Fund is registered under the
     1940 Act as a closed-end, non-diversified, management investment company
     and is organized as a Delaware limited liability company. The Fund's
     address is 345 Park Avenue, New York, New York 10154, and the Fund's
     telephone number is, c/o DWS Scudder Distributors Inc., (888) 262-0695.

o    WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF TENDERING INTERESTS? If
     you elect to tender all of your Interests in the Fund (and if we accept
     all of your Interests), you generally will recognize capital gain or loss
     to the extent of the difference between the proceeds you receive and your
     adjusted tax basis in your Interests. This capital gain or loss will be
     short-term or long-term depending upon your holding period for your
     Interests at the time gain or loss is recognized. Your long-term capital
     gain may be reduced as a result of the special allocations of short-term
     capital gains that the Fund intends to make to all Members whose tender
     of Interests is accepted. Your short-term capital loss may be reduced as
     a result of the special allocations of long-term capital loss that the
     Fund intends to make to all Members whose tender of Interests is
     accepted. You will recognize ordinary income to the extent your allocable
     share of the Fund's "unrealized receivables" exceeds your basis in such
     unrealized receivables, as determined pursuant to the Code and Treasury
     Regulations. If you tender less than all of your Interests to us for
     repurchase, you will recognize gain (but not loss) in a similar manner,
     but only to the extent that the amount of proceeds you receive exceeds
     your aggregate adjusted tax basis in all of your Interests.

To the Investors of
The Topiary Fund for Benefit Plan Investors (BPI) LLC:

          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 on the terms and
conditions set forth in this offer to repurchase ("Offer to Repurchase") and
the related Letter of Transmittal (which together with the Offer to Repurchase
constitutes the "Repurchase Offer") $10,142,360.05 (approximately 15% of the
net asset value of the Master Fund estimated as of February 28, 2006) of
limited liability interests in the Fund (the "Interests") or portions thereof
pursuant to tenders by investors. Members who tender all of their Interests
(and which are all accepted for repurchase by the Fund) will be paid a
repurchase price equal to the net asset value of their Interests as of June
30, 2006, 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"). If the Fund elects to extend the tender period for any reason, for the
purpose of determining such repurchase price, the net asset value of such
Interests will be determined as of the close of business on the last business
day of the calendar quarter in which the tender offer actually expires. This
Repurchase Offer is being made to all investors of the Fund ("Members") and is
not conditioned on any minimum amount of Interests being tendered, but is
subject to certain conditions described below. Interests in the Fund are not
traded on any established trading market and are subject to strict
restrictions on transferability pursuant to the Fund's Second Amended and
Restated Limited Liability Company Operating Agreement, dated as of June 2005
(the "LLC Agreement").

          Members should realize that the net asset value of the Fund likely
will change between February 28, 2006 (the last time the Fund's net asset
value was calculated), March 31, 2006 (the next time the Fund's net asset
value will be calculated) and June 30, 2006, when the value of the Interests
of Members making a full tender to the Fund will be determined for purposes of
calculating the repurchase price of such Interests. Members tendering all of
their Interests in the Fund should also note that although the Repurchase
Offer expires at 12:00 midnight, Eastern Time, Wednesday, April 26, 2006, or,
if the offer is extended, such time and date as the Fund designates in an
amended notice to Members ("Repurchase Request Deadline"), they remain Members
in the Fund until the Full Repurchase Valuation Date. Generally, the Fund
determines its net asset value monthly. Any tendering Members that wish to
obtain the most recently calculated net asset value of the Fund should contact
PFPC Inc., at the telephone number or address set forth below, Monday through
Friday, except holidays, during normal business hours of 9:00 a.m. to 5:00
p.m. (Eastern Time).

          Members desiring to tender all or any portion of their Interests in
accordance with the terms of the Repurchase Offer should complete and sign the
attached Letter of Transmittal and mail or fax it to the Fund in the manner
set forth below.



                                   IMPORTANT

          None of the Fund, DB Investment Managers, Inc., the Fund's
investment adviser ("Adviser"); any affiliate of the Adviser; or any of the
directors of the Fund makes any recommendation to any Member as to whether to
tender or refrain from tendering Interests. Members must make their own
decisions whether to tender Interests, and if so, the portion of their
Interests to tender.

          Because each Member's investment decision is a personal one based on
its financial circumstances, no person has been authorized to make any
recommendation on behalf of the Fund as to whether investors should tender
Interests pursuant to the Repurchase Offer. No person has been authorized to
give any information or to make any representations in connection with the
Repurchase Offer other than those contained herein or in the Letter of
Transmittal. If given or made, such recommendation and such information and
representations must not be relied on as having been authorized by the Fund.

          This transaction has not been approved or disapproved by the
Securities and Exchange Commission nor has the Securities and Exchange
Commission or any state securities commission passed on the fairness or merits
of such transaction or on the accuracy or adequacy of the information
contained in this document. Any representation to the contrary is unlawful.

          Questions and requests for assistance and requests for additional
copies of the Repurchase Offer may be directed to PFPC Inc., the Fund's

     1. Background and Purpose of the Repurchase Offer. The purpose of the
Repurchase Offer is to provide limited liquidity to Members who hold Interests
in the Fund. The Fund's prospectus, dated July 25, 2005 (the "Prospectus"),
provides that the Fund may offer, from time to time, pursuant to written
tenders, to repurchase its outstanding Interests from Members, and that the
directors of the Fund ("Directors") have the discretion to determine whether
the Fund will offer to repurchase its outstanding Interests. The Board of
Directors expects that the Fund will repurchase Interests from Members twice a
year, as of the last business day of June and December. Because there is no
secondary trading market for Interests in the Fund and transfers of Interests
are prohibited without prior approval of the Fund, the Directors have
determined, after consideration of various matters, including, but not limited
to, those set forth in the Prospectus, that the Repurchase Offer is in the
best interests of Members of the Fund to provide some liquidity for Interests
as contemplated in the Prospectus. The Directors intend to consider, in March
and September of each year, the continued desirability of the Fund making
offers to repurchase Interests, but the Fund is not required to make any such
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 repurchase of Interests pursuant to the Repurchase Offer will have
the effect of decreasing the net assets of the Fund and increasing the
proportionate interest in the Fund of Members who do not tender Interests. A
reduction in the net assets of the Fund could limit the Master Fund's, and in
turn the Fund's, access to certain investment opportunities, cause the Master
Fund to sell assets it would not have sold otherwise (including public
securities), or result in Members who do not tender Interests bearing higher
costs to the extent that certain expenses borne by the Fund are relatively
fixed and may not decrease if assets decline. The effects of decreased Fund
size and increased proportionate Interests of Members who do not tender may be
reduced or eliminated to the extent that additional subscriptions for
Interests in the Fund are made from time to time.

     Interests that are tendered to the Fund in connection with this
Repurchase Offer will be retired. The Fund may issue Interests to "Eligible
Investors," as that term is defined in the Prospectus, from time to time. The
Fund currently expects that it will continue to accept subscriptions for
Interests on a monthly basis.

     2. Offer to Repurchase and Price. The Fund will repurchase, upon the
terms and subject to the conditions of the Repurchase Offer, up to
$10,142,360.05 (approximately 15% of the net asset value of the Master Fund
estimated as of February 28, 2006) of limited liability company interests that
are properly tendered by and not withdrawn (in accordance with Section 5
below) before the Repurchase Request Deadline. The Fund reserves the right to
extend, amend or cancel the Repurchase Offer, or postpone the acceptance of
Interests tendered pursuant to the Repurchase Offer, as described in Sections
3 and 7 below. The amount due to any Member who tenders all of its Interests
(and which are all accepted for repurchase by the Fund) will be equal to the
value of such Member's capital account based on the Fund's net asset value as
of June 30, 2006 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's net
asset value as of June 30, 2006 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 tendering 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.


                                      4


     As of the close of business on February 28, 2006, there was approximately
$66,492,290.99 outstanding in capital of the Fund and $67,615,733,68
outstanding in capital of the Master Fund. Generally, the Fund and the Master
Fund determine their net asset values monthly. Members may obtain the most
recently calculated information regarding the net asset value of the Fund and
their Interests by contacting PFPC Inc., at the telephone number or address
set forth on page 2, Monday through Friday, except holidays, during normal
business hours of 9:00 a.m. to 5:00 p.m. (Eastern Time). Of course, the net
asset value of Interests in the Fund likely will change between February 28,
2006 (the last time net asset value was calculated), March 31, 2006 (the next
time it will be calculated), and June 30, 2006, the Full Repurchase Valuation
Date.

     3. Amount of Tender. Members may tender all their Interests or a portion
of their Interests in the Fund. The Repurchase Offer is being made to all
Members of the Fund and is not conditioned on any minimum amount of Interests
being tendered. If you tender a portion of your Interests, you must leave an
amount equal to at least $25,000 in the Fund (the "Required Minimum Balance").
The Fund reserves the right to reduce the amount of Interests repurchased from
you so that the Required Minimum Balance is maintained.

     If the amount of the Interests that are properly tendered pursuant to the
Repurchase Offer, and not withdrawn pursuant to Section 5 below, is less than
or equal to $10,142,360.05 (or such greater amount as the Fund may elect to
repurchase pursuant to the Repurchase Offer), the Fund will, on the terms and
subject to the conditions of the Repurchase Offer, repurchase all of the
Interests so tendered unless the Fund elects to cancel or amend the Repurchase
Offer, or postpone acceptance of tenders made pursuant to the Repurchase
Offer, as provided in Section 7 below. If more than $10,142,360.05 are duly
tendered to the Fund before the Repurchase Request Deadline and not withdrawn
pursuant to Section 5 below, the Fund will, in its sole discretion, either (a)
purchase an additional amount of Interests not to exceed 2% of the net asset
value of the Fund as of the Repurchase Request Deadline in conformity with
Rule 13e-4(f)(1)(ii) under the Securities Exchange Act of 1934; (b) extend the
Repurchase Offer, if necessary, and increase the amount of Interests that the
Fund is offering to repurchase, to an amount it believes sufficient to
accommodate the excess Interests tendered as well as any Interests tendered
during the extended Repurchase Offer; or (c) accept Interests tendered on or
before the Repurchase Request Deadline for payment on a pro-rata basis based
on the aggregate net asset value of tendered Interests. The Repurchase Offer
may be extended, amended or canceled in various other circumstances described
in Section 7 below.

     4. Procedure for Tenders. Members wishing to tender Interests pursuant to
the Repurchase Offer should mail a completed and executed Letter of
Transmittal to PFPC Inc., to the attention of The Topiary Fund for Benefit
Plan Investors (BPI) LLC, at the address set forth on page 2, or fax a
completed and executed Letter of Transmittal to PFPC Inc., also to the
attention of The Topiary Fund for Benefit Plan Investors (BPI) LLC, at the fax
numbers set forth on page 2. The completed and executed Letter of Transmittal
must be received by PFPC Inc., either by mail or by fax, no later than the
Repurchase Request Deadline. The Fund recommends that all documents be
submitted to PFPC Inc. by certified mail, return receipt requested, or by
facsimile transmission. An investor choosing to fax a Letter of Transmittal to
PFPC Inc. must also mail the original completed and executed Letter of
Transmittal to PFPC Inc. promptly thereafter. If a Member elects to tender, it
is the tendering Member's responsibility to confirm receipt of the Letter of
Transmittal or other document with PFPC Inc.

     Members wishing to confirm receipt of a Letter of Transmittal may contact
PFPC Inc. at the address and phone number set forth on page 2. The method of
delivery of any documents is at the election and complete risk of the Member
tendering its Interests in the Fund, including, but not limited to, the
failure of PFPC Inc. to receive any Letter of Transmittal or other document.
All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of tenders will be determined by the Fund, in its sole
discretion, and such determination shall be final and binding. The Fund
reserves the absolute right to reject any or all tenders determined by it not
to be in appropriate form or the acceptance of or payment for which would, in
the opinion of counsel for the Fund, be unlawful. The Fund also reserves the
absolute right to waive any of the conditions of the Repurchase Offer or any
defect in any tender with respect to any particular Member, and the Fund's
interpretation of the terms and conditions of the Repurchase Offer will be
final and binding. Unless waived, any defects or irregularities in connection
with tenders must be cured within such time as the Fund shall determine.
Tenders will not be deemed to have been made until the defects or
irregularities have been cured or waived. Neither the Fund, the Adviser nor
the Directors shall be obligated to give notice of any defects or
irregularities in tenders, nor shall any of them incur any liability for
failure to give such notice.


                                      5


     5. Withdrawal Rights. Any Member tendering Interests pursuant to this
Repurchase Offer may withdraw its tender at any time on or before the
Repurchase Request Deadline. To be effective, any notice of withdrawal must be
timely received by PFPC Inc. at the address or fax numbers set forth on page
2. A form to use to give notice of withdrawal is enclosed herewith. All
questions as to the form and validity (including time of receipt) of notices
of withdrawal will be determined by the Fund, in its sole discretion, and such
determination shall be final and binding. Interests properly withdrawn shall
not thereafter be deemed to be tendered for purposes of the Repurchase Offer.
However, withdrawn Interests may be tendered prior to the Repurchase Request
Deadline by following the procedures described in Section 4.

     6. Repurchases and Payment. For purposes of the Repurchase Offer, the
Fund will be deemed to have accepted Interests that are tendered if and when
it gives oral or written notice to the tendering Member of its election to
repurchase such Interests. As stated in Section 2 above, the repurchase price
paid to Members who tender all of their Interests in the Fund (and which are
all accepted for repurchase by the Fund) will be the net asset value thereof
as of the Full Repurchase Valuation Date. If the Fund elects to extend the
tender period for any reason, the net asset value of such Interests, for the
purpose of determining their repurchase price, will be determined as of the
close of business on the last business day of the calendar quarter in which
the tender offer actually expires.

     Within five days of the Repurchase Request Date, or no later than May 2,
2006, each Member whose Interests or portion thereof has 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 such Member's capital account (or portion
thereof) being repurchased. For Members who tender all of their Interests in
the Fund (and which are all accepted for repurchase by the Fund), the
repurchase price for such Interests will be determined as of the Full
Repurchase Valuation Date (after giving effect to all allocations to be made
as of that date to such Member's capital account).

     For both a Member making full or partial tenders of their Interests, the
note will entitle the Member to be paid within thirty (30) days after the Full
Repurchase Valuation Deadline, 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 later (either such date, a "Payment Date").
Notwithstanding the foregoing, if a Member has requested the repurchase of 90%
or more of the Interests held by such Member, such Member shall receive (i)
cash or a non-transferable promissory note, which need not bear interest, in
an amount equal to 90% of the estimated unaudited net asset value of such
Member's capital account (or portion thereof) being repurchased, determined,
only with respect to a Member making a full tender of its Interests, as of the
Full Repurchase Valuation Date (after giving effect to all allocations to be
made as of that date to such Member's capital account) (the "Initial
Payment"), which will be paid on or prior to the Payment Date; and (ii) a
promissory note entitling the holder thereof to the balance of the proceeds,
to be paid following the later of (x) 90 days following the applicable Full
Repurchase Valuation Date (for both a Member making a full or partial tender
of its Interests), so as to effectuate the orderly liquidation of enough
Investment Funds in which the Master Fund is invested or otherwise, or (y)
such longer period as the Board of Directors in its discretion deems necessary
to protect the interests of the remaining Members. Payment for tendered
Interests that are accepted for repurchase will generally be made via wire
transfer in accordance with the instructions provided in the Letter of
Transmittal.

     The Fund expects that payment for Interests acquired pursuant to the
Repurchase Offer will be derived from the following sources: cash on hand,
proceeds from the redemption of interests in the Investment Funds in which the
Master Fund invests, or borrowings. Payment may be delayed if it is determined
to redeem the Master Fund's interests in Investment Funds to make such
payments, but has experienced unusual delays in receiving payments from the
Investment Funds. None of the Fund, the Master Fund, the Adviser or Directors
has determined 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 Board in its discretion may pay repurchase proceeds, in whole or in
part, in securities of equivalent value. The Fund does not expect that it will
distribute securities as payment for repurchased Interests except in unusual
circumstances, such as in the unlikely event that (i) making a cash payment
would result in a material


                                      6


adverse effect on the Fund or on Members not requesting that their Interests
be repurchased or (ii) that the Master Fund has received distributions from
Investment Funds in the form of securities that are transferable to the
Members. In the event that the Fund makes such a distribution of securities as
payment for Interests, Members will bear any risks of the distributed
securities and may be required to pay a brokerage commission or other costs in
order to dispose of such securities.

     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.

     7. Certain Conditions of the Repurchase Offer. The Fund reserves the
right, at any time and from time to time, to extend the period of time during
which the Repurchase Offer is pending by notifying Members of such extension.
If the Fund elects to extend the tender period for any reason, for the purpose
of determining the repurchase price paid to Members tendering all of their
Interests in the Fund (and which are all accepted for repurchase by the Fund),
the net asset value of such Interests will be determined as of the close of
business on the last business day of the calendar quarter in which the tender
offer actually expires. During any such extension, all Interests previously
tendered and not withdrawn will remain subject to the Repurchase Offer. The
Fund also reserves the right, at any time and from time to time, up to and
including acceptance of tenders pursuant to the Repurchase Offer, in the
circumstances set forth in the following paragraph, to: (a) cancel the
Repurchase Offer and in the event of such cancellation, not to repurchase or
pay for any Interests tendered pursuant to the Repurchase Offer; (b) suspend
or amend the Repurchase Offer; or (c) postpone the acceptance of Interests. If
the Fund determines to amend the Repurchase Offer or to postpone the
acceptance of Interests tendered, it will, to the extent necessary, extend the
period of time during which the Repurchase Offer is open as provided above and
will promptly notify Members.

     The Fund may cancel, suspend or amend the Repurchase Offer, or postpone
the acceptance of tenders made pursuant to the Repurchase Offer, by vote of a
majority of the Board, including a majority of the Directors who are not
"interested persons," within the meaning of the Investment Company Act of
1940, as amended ("Independent Directors"), of the Fund, including but not
limited to: (a) for any period during which an emergency exists as a result of
which it is not reasonably practicable for the Master Fund to dispose of
securities it owns or to determine the value of the Fund's and/or the Master
Fund's net assets; (b) for any other periods that the SEC permits by order for
the protection of Members; or (c) under such other unusual circumstances as
the Board deems advisable for the benefit of the Fund and its Members. For
example, the Fund may cancel, suspend or amend the Repurchase Offer, or
postpone the acceptance of tenders made pursuant to the Repurchase Offer, if
(a) the Master Fund would not be able to dispose of securities it owns in a
manner that is orderly and consistent with the Fund's and the Master Fund's
investment objectives and policies in order for the Fund to repurchase
Interests tendered pursuant to the Repurchase Offer; or (b) there is any (i)
legal action or proceeding instituted or threatened challenging the Repurchase
Offer or that otherwise would have a material adverse affect on the Fund
and/or the Master Fund, (ii) declaration of a banking moratorium by Federal or
state authorities or any suspension of payment by banks in the United States
or New York State that is material to the Fund and/or the Master Fund, (iii)
limitation imposed by Federal or state authorities on the extension of credit
by lending institutions, (iv) suspension of trading on any organized exchange
or over-the-counter market where the Master Fund has a material investment,
(v) commencement of war, armed hostilities or other international or national
calamity directly or indirectly involving the United States that is material
to the Fund and/or the Master Fund, or (vi) material decrease in the estimated
net asset value of the Fund and the Master Fund from the net asset value of
the Fund and the Master Fund as of the commencement of the Repurchase Offer.
However, there can be no assurance that the Fund will exercise its right to
extend, amend or cancel the Repurchase Offer or to postpone acceptance of
tenders pursuant to the Repurchase Offer.

     8. Certain Information About the Fund. The Fund is registered under the
1940 Act as a closed-end, non-diversified, management investment company and

                                      7


     Neither the Fund nor the Master Fund has any plans or proposals that
relate to or would result in: (a) the acquisition by any person of further
Interests in the Fund (other than the Fund's intention to accept subscriptions
for Interests from time to time in the discretion of the Fund) or the
disposition of Interests, other than as disclosed in the Prospectus; (b) an
extraordinary transaction, such as a merger, reorganization or liquidation,
involving the Fund and/or the Master Fund; (c) any material change in the
present distribution policy or indebtedness or capitalization of the Fund
and/or the Master Fund; (d) any change in the identity of the Adviser or
Directors of the Fund and the Master Fund, or in the management of the Fund
and the Master Fund including, but not limited to, any plans or proposals to
change the number or the term of the Directors of the Fund and the Master
Fund, to fill any existing vacancy for a Director of the Fund and the Master
Fund or to change any material term of the investment advisory arrangements
with the Adviser; (e) a sale or transfer of a material amount of assets of the
Fund and/or the Master Fund (other than as the Directors determine may be
necessary or appropriate to fund any portion of the repurchase price for
Interests acquired pursuant to this Repurchase Offer or in connection with the
ordinary portfolio transactions of the Master Fund ); (f) any other material
change in the Fund's and/or the Master Fund's structure or business, including
any plans or proposals to make any changes in its fundamental investment
policy for which a vote would be required by Section 13 of the 1940 Act; or
(g) any changes in the LLC Agreement or other actions that may impede the
acquisition of control of the Fund and/or the Master Fund by any person.

     During the past 60 days, other than the monthly acceptance of
subscriptions for Interests, no transactions involving the Interests were
effected by the Fund, the Adviser of the Fund, the Directors or any person
controlling the Fund or controlling the Adviser or any Directors of the Fund.

     As of February 28, 2006, the Adviser, indirectly through an affiliate,
beneficially owned $1,123,422.69, or approximately 1.66%. This ownership
reflects such affiliate's initial contribution of capital to the Master Fund
of $25,000,000 prior to the Interests in the Fund being publicly offered.

     The Fund has been informed that such affiliate of the Adviser tendered
$1,142,986 of Interests in the Master Fund, of which $1,142,986 was accepted
for repurchase by the Master Fund as of December 31, 2005, and that such
affiliate of the Adivser does not intend to tender any amount of its Interest
in the Master Fund in the Master Fund's Repurchase Offer.

     9. Certain Federal Income Tax Consequences. The following discussion is a
general summary of certain Federal income tax consequences to Members that are
subject to Federal income taxation of the repurchase of Interests by the Fund
from Members pursuant to the Repurchase Offer. Members should consult their
own tax advisers for a complete description of the tax consequences to them of
a repurchase of their Interests by the Fund pursuant to the Repurchase Offer.

     A Member who tenders all its Interests (and whose entire interest is
accepted) to the Fund for repurchase generally will recognize capital gain or
loss to the extent of the difference between the proceeds received by such
Member and such Member's adjusted tax basis in its Interests in the Fund. This
capital gain or loss will be short-term or long-term depending upon the
Member's holding period for its Interests at the time the gain or loss is
recognized. A tendering Member will recognize ordinary income to the extent
such Member's allocable share of the Fund's "unrealized receivables" exceeds
the Member's basis in such unrealized receivables, as determined pursuant to
the Treasury Regulations. A Member who tenders less than all its Interests to
the Fund for repurchase will recognize gain (but not loss) in a similar manner
only to the extent that the amount of the proceeds received exceeds such
Member's aggregate adjusted tax basis in all its Interests.

     A Member's basis in its Interests is adjusted for income, gain or loss
allocated (for tax purposes) to such Member for periods until such Member
ceases to be a Member of the Fund. Pursuant to the authority granted to it
under the LLC Agreement, the Adviser intends to specially allocate items of
Fund capital gain, including short-term capital gain, to a withdrawing Member
to the extent its liquidating distribution would otherwise exceed its adjusted
tax basis in its Interests. Such a special allocation may result in the
withdrawing Member recognizing capital gain, which may include short-term
gain, in the Member's last taxable year in the Fund, thereby potentially
reducing the amount of any long-term capital gain that, absent the special
allocation, would otherwise have been recognized by the withdrawing Member.


                                      8


     Pursuant to the authority granted to it under the LLC Agreement, the
Adviser intends to specially allocate items of Fund capital loss, including
long-term capital loss, to a withdrawing Member to the extent its liquidating
distribution would otherwise be less than its adjusted tax basis in its
Interests. Such a special allocation may result in the withdrawing Member
recognizing capital loss, which may include long-term capital loss, in the
Member's last taxable year in the Fund, thereby potentially reducing the
amount of any short-term capital loss that, absent the special allocation,
would otherwise have been recognized by the withdrawing Member.

     10. Miscellaneous. The Repurchase Offer is not being made to, nor will
tenders be accepted from, Members in any jurisdiction in which the Repurchase
Offer or its acceptance would not comply with the securities or Blue Sky laws
of such jurisdiction. The Fund reserves the right to exclude Members from the
Repurchase Offer in any jurisdiction in which it is asserted that the
Repurchase Offer cannot lawfully be made. The Fund believes such exclusion is
permissible under applicable laws and regulations, provided the Fund makes a
good faith effort to comply with any state law deemed applicable to the
Repurchase Offer.

     The financial information of each of the Fund and the Master Fund for the
period from October 1, 2004 (commencement of operations) through March 31,
2005 is incorporated by reference to each of the Fund's and the Master Fund's
audited financial statements, both of which were previously filed on EDGAR on
Form N-CSR on June 6, 2005 and which were prepared and furnished to members
pursuant to Rule 30d-l under the 1940 Act and filed with the Securities and
Exchange Commission pursuant to Rule 30b2-1 under the 1940 Act.

     The Fund has filed an Issuer Tender Offer Statement on Schedule TO with
the Securities and Exchange Commission, which includes certain information
relating to the Repurchase Offer summarized herein. A free copy of such

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The undersigned hereby tenders to The Topiary Fund for Benefit Plan
Investors (BPI) LLC, a closed-end, non-diversified, management investment
company organized under the laws of the State of Delaware (the "Fund"), the
limited liability company interests in the Fund or portion thereof held by the
undersigned ("Interests"), described and specified below, on the terms and
conditions set forth in the offer to repurchase, dated March 22, 2006 ("Offer
to Repurchase"), receipt of which is hereby acknowledged, and in this Letter
of Transmittal (which together constituted the "Repurchase Offer"). The tender
and this Letter of Transmittal are subject to all the terms and conditions set
forth in the Offer to Repurchase, including, but not limited to, the absolute
right of the Fund to reject any and all tenders determined by it, in its sole
discretion, not to be in the appropriate form.

     The undersigned hereby sells to the Fund Interests tendered hereby
pursuant to the Repurchase Offer. The undersigned hereby warrants that the
undersigned has full authority to Interests tendered hereby and that the Fund
will acquire good title thereto, free and clear of all liens, charges,
encumbrances, conditional sales agreements or other obligations relating to
the sale thereof, and not subject to any adverse claim, when and to the extent
the same are repurchased by it. Upon request, the undersigned will execute and
deliver any additional documents necessary to complete the sale in accordance
with the terms of the Repurchase Offer.

     The undersigned recognizes that under certain circumstances set forth in
the Repurchase Offer, the Fund may not be required to repurchase any of the
Interests tendered hereby. The undersigned recognizes that, if the Repurchase
Offer is oversubscribed, not all of the undersigned's Interests will be
repurchased.

     The undersigned acknowledges that the method of delivery of any documents
is at the election and the complete risk of the undersigned, including, but
not limited to, the failure of the Fund's administrator, PFPC Inc., to receive
any Letter of Transmittal or other document.

     Payment for tendered Interests that are accepted for repurchase will
generally be made via wire transfer. For Members who tender all of their
Interests (and which are all accepted for repurchase by the Fund), the amount
of the payment will be based on the Fund's net asset value, the calculation of
which is described in the Fund's Prospectus under the heading "Net Asset
Valuation," as of June 30, 2006, or, if the Repurchase Offer is extended, as
of a date designated by the Fund in an amended notice to Members.

     All authority herein conferred or agreed to be conferred shall survive
the death or incapacity of the undersigned and the obligation of the
undersigned hereunder shall be binding on the heirs, personal representatives,
successors and assigns of the undersigned. Except as stated in Section 5 of
the Offer to Repurchase, this tender is irrevocable.

     If you do not want to sell your limited liability company interests at
this time, please disregard this notice. This is simply notification of the
Fund's tender offer. If you choose to tender, you are responsible for
confirming that PFPC Inc. has received your documents. To assure good
delivery, please send this Letter of Transmittal to PFPC Inc. and not to your
Financial Advisor.

                     enclosed postage-paid envelope (if by mail) as instructed
                     on the following pages.
