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 $12,994,898
(approximately 15% of the net asset value of the Master Fund estimated as of
September 30, 2006) of limited liability company Interests that are tendered by
Members and not withdrawn prior to 12:00 midnight, Eastern Time, on October 27,
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 December 31, 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 December 31, 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, Friday, October 27, 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
Friday, October 27, 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 Friday, October 27, 2006). Of course,
the net asset value of the Interests in the Fund will change between August 31,
2006 (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, 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 Friday, October 27, 2006. Also realize that although the
Repurchase Offer expires on October 27, 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 December 31, 2006, when the value of that Member's
Interests is determined.

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

to the Fund's prospectus contained in a post-effective amendment to the Fund's
registration statement on Form N-2, as filed with the SEC via EDGAR on July 26,
2006, and as disclosed in the Fund's prospectus dated July 26, 2006 (the
"Prospectus"), the Fund's Board of Directors has sole discretion to determine
whether the Fund will repurchase Interests from Members from time to time
pursuant to written tenders. 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. Neither the Fund nor the Master Fund is aware of any

Member that has submitted a written request, in accordance with the 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 or multiple
consecutive offers within the two-year period). A Member who intends to cause
the Fund to be dissolved must so indicate in a separate written request
submitted within the applicable two-year period.

     If you do not want to sell your limited liability company interests at
                    this time, please disregard this notice.
                      This is simply a notification of the
                              Fund's tender offer.

September 25, 2006


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

                  We are writing to inform you of important dates related to the
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 September 25, 2006
and end on October 27, 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 December 31, 2006 (the
"Full Repurchase Valuation Date"). Members tendering Interests for repurchase
will be given a promissory note no later than November 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 Plan Investors (BPI) LLC, in which substantially all of
the Fund's assets are invested, has received from the Investment Funds in which
it invests, 90% of the amount needed to fund the repurchase of Interests,
whichever is later. The purpose of the tender offer is to provide some liquidity
to investors who hold Interests in the Fund. Interests can be redeemed by means
of a tender offer only during one of the Fund's announced repurchase offers.

The Topiary Fund for Benefit Plan Investors (BPI) LLC



                                                              EXHIBIT (a)(1)(ii)



              THE TOPIARY FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
                                 345 Park Avenue
                            New York, New York 10154

    OFFER TO REPURCHASE $12,994,898 (APPROXIMATELY 15% OF THE NET ASSET VALUE
             OF THE MASTER FUND ESTIMATED AS OF SEPTEMBER 30, 2006)
                     OF LIMITED LIABILITY COMPANY INTERESTS

                 THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT
           12:00 MIDNIGHT, EASTERN TIME, ON FRIDAY, OCTOBER 27, 2006,
                          UNLESS THE OFFER IS EXTENDED

                               SUMMARY TERM SHEET

o        WHAT IS THE 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 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
         $12,994,898 (approximately 15% of the net asset value of the Master
         Fund estimated as of September 30, 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,
         Friday, October 27, 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 December 31, 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, October 27, 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,
         October 27, 2006). Of course, the net asset value of Interests in the
         Fund is likely to change between August 31, 2006 (the last time the
         Fund's net asset value was calculated), September 30, 2006 (the next
         time it will be calculated), and December 31, 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 October 27, 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 November 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.



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, October 27, 2006. Also realize that
         although the tender offer expires on 12:00 midnight, October 27, 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
         December 31, 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.



              THE TOPIARY FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
                                 345 Park Avenue
                            New York, New York 10154

    OFFER TO REPURCHASE $12,994,898 (APPROXIMATELY 15% OF THE NET ASSET VALUE
             OF THE MASTER FUND ESTIMATED AS OF SEPTEMBER 30, 2006)
                     OF LIMITED LIABILITY COMPANY INTERESTS

                 THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT
           12:00 MIDNIGHT, EASTERN TIME, ON FRIDAY, OCTOBER 27, 2006,
                          UNLESS THE OFFER IS EXTENDED


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") $12,994,898
(approximately 15% of the net asset value of the Master Fund estimated as of
September 30, 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
December 31, 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 August 31, 2006 (the last time the Fund's net asset
value was calculated), September 30, 2006 (the next time the Fund's net asset
value will be calculated) and December 31, 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, Friday, October 27, 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 Administrator.

         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 26, 2006 (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 $12,994,898
(approximately 15% of the net asset value of the Master Fund estimated as of
September 30, 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 December 31, 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 December 31,
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 August 31, 2006, there was approximately
$81,903,445 outstanding in capital of the Fund and $83,593,197 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 August 31, 2006 (the last time net asset
value was calculated), September 30, 2006 (the next time it will be calculated),
and December 31, 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 $12,994,898 (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 $12,994,898 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
November 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 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. Interests in the Fund are not
traded on any established trading market and are subject to strict restrictions
on transferability pursuant to the LLC Agreement. The Fund's Directors are Nolan
T. Altman, Louis S. Citron and Edward T. Tokar. Their address is c/o DB Absolute
Return Strategies, 345 Park Avenue, New York, New York 10154.

                                       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 August 31, 2006, the Adviser, indirectly through an affiliate,
beneficially owned $1,270,456, or approximately 1.52%. 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 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.

         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

                                       8


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 fiscal year ending March 31, 2006 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 9, 2006 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
statement may be obtained from the Fund by contacting PFPC Inc. at the address
and phone number set forth on page 2 or from the Securities and Exchange

               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 September 25, 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 December 31, 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.


                                    Please fax or mail (the following pages
                                    only) in the enclosed postage-paid envelope
