ITEM 1.        SUMMARY TERM SHEET.

               As stated in the Limited  Liability  Company  Agreement (the "LLC
Agreement") of Old Mutual Absolute Return Master Fund,  L.L.C.  (the "Company"),
the Company is offering to purchase limited  liability  company interests in the
Company ("Interest" or "Interests," as the context requires) from members of the
Company  ("Members")  at their  net  asset  value  (that  is,  the  value of the
Company's assets minus its liabilities, multiplied by the proportionate interest
in the Company a Member desires to tender). The offer to purchase Interests (the
"Offer")  will remain open until 12:00  midnight,  Eastern  time, on January 25,
2008 (the "Expiration  Date") unless the Offer is extended.  The net asset value
of the Interests will be calculated for this purpose as of March 31, 2008 or, if
the Offer is extended,  approximately  one month after the  Expiration  Date (in
each case, the "Valuation  Date").  The Company reserves the right to adjust the
Valuation  Date as a result of any  extension  of the Offer.  The  Company  will
review the net asset value  calculation of Interests  during the Company's audit
for its fiscal year ending  March 31,  2008,  which the Company  expects will be
completed by the end of May 2008 and the audited net asset value will be used to
determine the final amount to be paid for tendered Interests.

               Members  may tender  their  entire  Interest,  a portion of their
Interest  (defined as a specific  dollar  value) or a portion of their  Interest
above the required  minimum  capital  account  balance.  If a Member tenders its
entire  Interest (or a portion of its Interest) and the Company  purchases  that
Interest,   the   Company   will  give  the  Member  a   non-interest   bearing,
non-transferable promissory note (the "Note") entitling the Member to receive an
amount  equal  to the net  asset  value  of the  Interest  tendered  (valued  in
accordance  with the LLC  Agreement),  determined as of the Valuation  Date. The
Note will  entitle  the  Member to receive  an  initial  payment in cash  and/or
marketable securities (valued in accordance with the LLC Agreement) equal to 97%
of the net asset value of the  Interest  tendered by the Member that is accepted
for  purchase by the Company  (the  "Initial  Payment")  and will be paid to the
Member  within  one  month  after the  Valuation  Date or,  if the  Company  has
requested  withdrawals  of its  capital  from  any  portfolio  funds in order to
finance the purchase of  Interests,  within ten business  days after the Company
has received at least 90% of the aggregate  amount withdrawn by the Company from
such  portfolio  funds.  The Note  will also  entitle  the  Member to  receive a
contingent  payment (the "Contingent  Payment") equal to the excess,  if any, of
(a) the net asset value of the Interest tendered as of the Valuation Date, as it
may be adjusted  based upon the next  annual  audit of the  Company's  financial
statements,  over (b) the Initial  Payment.  The Fund will deposit the aggregate
amount of the Contingent Payments in a separate,  non-interest  bearing account.
The  Contingent  Payment will be payable  promptly  after the  completion of the
Company's  annual  audit.  Proceeds  of the Initial  Payment and the  Contingent
Payment  will be wire  transferred  directly  to an  account  designated  by the
Member.

               A Member  that  tenders  for  repurchase  only a portion  of such
Member's Interest will be required to maintain a minimum capital account balance
of $50,000  (or  $25,000,  in the case of certain  Members,  as set forth in the
offering materials provided to Members).

               The Company  reserves the right to purchase  less than the amount
tendered by a Member if the amount  tendered  would cause the  Member's  capital
account in the Company to have a value less than the required  minimum  balance.
If the Company  accepts the tender of the Member's  entire Interest or a portion



                                       1



of such  Member's  Interest,  the Company  will make  payment for  Interests  it
purchases from one or more of the following sources:  cash on hand, the proceeds
of the sale of and/or delivery of portfolio  securities held by the Company, the
withdrawals of its capital from portfolio funds in which it has invested,  or by
borrowings (which the Company does not intend to do).

               The Offer remains open to Members until 12:00  midnight,  Eastern
time, on January 25, 2008, the expected expiration date of the Offer. Until this
time,  Members  have the right to change their minds and withdraw the tenders of
their  Interests.  Members will also have the right to withdraw tenders of their
Interests at any time after  February 27,  2008,  if their  Interest has not yet
been accepted for purchase by the Company.

               If a Member  would like the Company to purchase its Interest or a
portion  of its  Interest,  it 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 C, to Citi Fund Services (the
"Transfer  Agent"),  at  3  Canal  Plaza,  Ground  Floor,  Portland,  ME  04101,
Attention:  Tender Offer Administrator,  or (ii) fax it to the Transfer Agent at
(207) 879-6206,  so that it is received before 12:00 midnight,  Eastern time, on
January 25, 2008.  IF THE MEMBER  CHOOSES TO FAX THE LETTER OF  TRANSMITTAL,  IT
SHOULD MAIL THE ORIGINAL  LETTER OF  TRANSMITTAL  TO THE TRANSFER AGENT PROMPTLY
AFTER IT IS FAXED  (ALTHOUGH  THE ORIGINAL  DOES NOT HAVE TO BE RECEIVED  BEFORE
12:00 MIDNIGHT,  EASTERN TIME, ON JANUARY 25, 2008). Of course, the value of the
Interests will change between  October 31, 2007 (the last time prior to the date
of this  filing  as of  which  net  asset  value  has been  calculated)  and the
Valuation  Date.  Members  may obtain  the  estimated  net asset  value of their
Interests,  which the Company will calculate  monthly based upon the information
the  Company  receives  from the  managers  of the  portfolio  funds in which it
invests,  by contacting  the Transfer  Agent at (800) 838-0232 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 see Item 4(a)(9) for a
discussion  regarding  the  procedures  implemented  in the  event  the Offer is
oversubscribed (I.E., more than $1 million of Interests are duly tendered).

               Please  note that just as each  Member has the right to  withdraw
the  tender  of an  Interest,  the  Company  has the right to  cancel,  amend or
postpone this Offer at any time before 12:00 midnight,  Eastern time, on January
25, 2008.  Also realize that  although the Offer  expires on January 25, 2008, a
Member  that  tenders  its  Interest   will  remain  a  Member  in  the  Company
notwithstanding  the Company's  acceptance of the Member's Interest for purchase
through the Valuation Date.  Accordingly,  the value of a tendered Interest will
remain at risk, until the Valuation Date, because of its investment  pursuant to
the Company's investment program.

ITEM 4.        TERMS OF THIS TENDER OFFER.

               (a)(1)  Subject to the  conditions  set forth in the  Offer,  the
Company will purchase up to $1 million of Interests that are tendered by Members
and not withdrawn (in accordance with Item 1) prior to 12:00  midnight,  Eastern
time, on the Expiration  Date, or any later date as corresponds to any extension
of the offer.

                  (2) The  purchase  price of  Interests tendered to the Company
for purchase will be their net asset value as of the Valuation Date.

                  Members  may  tender  their  entire  Interest,  a  portion  of
their Interest defined as a specific dollar value or a portion of their Interest
above the required minimum capital account balance.  Each Member who tenders its
entire Interest or a portion thereof that is accepted for purchase will be given
a Note promptly upon acceptance of the Member's Interest.  The Note will entitle
the  Member  to be paid an  amount  equal  to the  value,  determined  as of the
Valuation Date, of the Interest or portion  thereof being purchased  (subject to
adjustment upon  completion of the next annual audit of the Company's  financial
statements).  This amount will be the value of the Member's  capital account (or
the portion  thereof being  purchased)  determined as of the Valuation Date, and
will be based upon the net asset value of the Company's  assets as of that date,
after giving effect to all allocations to be made as of that date. The Note will
entitle the Member to receive an initial  payment in an amount equal to at least
97% of the unaudited  net asset value of the Interest  tendered and accepted for
purchase  by the  Company.  Payment of this amount will be made within one month
after the


                                       3



Valuation Date or, if the Company has requested  withdrawals of its capital from
any portfolio  funds in order to fund the purchase of  Interests,  no later than
ten business  days after the Company has received at least 90% of the  aggregate
amount  withdrawn by the Company from such portfolio  funds.  The Note will also
entitle a Member to receive the Contingent Payment.  The Contingent Payment will
be payable  promptly after the completion of the Company's next annual audit. It
is anticipated that the annual audit of the Company's financial  statements will
be  completed  within 60 days after March 31,  2008,  the fiscal year end of the
Company.

                  Although  the  Company  has  retained  the  option  to pay all
or a portion of the purchase price by distributing  marketable  securities,  the
purchase  price will be paid entirely in cash except in the unlikely  event that
the  Board of  Managers  of the  Company  determines  that the  distribution  of
securities is necessary to avoid or mitigate any adverse  effect of the Offer on
the remaining Members.

                  The Note  pursuant to  which a tendering  Member will  receive
the Initial Payment and Contingent Payment  (together,  the "Cash Payment") will
be mailed directly to the tendering Member. Any Cash Payment due pursuant to the
Note  will be made by wire  transfer  directly  to the  tendering  Member  to an
account designated by the Member.

                  A Member who  tenders  for  repurchase  only a portion of such
Member's Interest will be required to maintain a minimum capital account balance
of $50,000  (or  $25,000,  in the case of certain  Members,  as set forth in the
offering materials provided to the Members).

                  A copy of:  (a)  the Cover  Letter to  the  Offer to  Purchase
and Letter of  Transmittal;  (b) Notice of the Offer to Purchase;  (c) a form of
Letter of  Transmittal;  (d) a form of Notice of Withdrawal  of Tender;  and (e)
forms of Letters  from the  Company to Members  that will be sent in  connection
with the Company's  acceptance of tenders of Interests,  are attached  hereto as
Exhibits A, B, C, D and E, respectively.

                  (3) The scheduled expiration date of the Offer is 12:00
midnight, Eastern time, January 25, 2008.

                  (4) Not Applicable.

                  (5) The Company  reserves the right, at any time and from time
to time,  to extend  the  period of time  during  which the Offer is  pending by
notifying Members of such extension.  The purchase price of an Interest tendered
by any Member will be the net asset value thereof as of the close of business on
March 31, 2008 if the Offer  expires on the initial  Expiration  Date or, if the
Offer is extended, approximately one month after the Expiration Date. During any
such extension,  all Interests previously tendered and not withdrawn will remain
subject to the Offer.  The Company also reserves the right, at any time and from
time to time, up to and including the Expiration  Date, to: (a) cancel the Offer
in the  circumstances  set  forth in  Section 7 of the Offer and in the event of
such cancellation, not to purchase or pay for any Interests tendered pursuant to
the Offer; (b) amend the Offer; and (c) postpone the acceptance of Interests. If
the Company determines to amend the Offer or to postpone the acceptance of


                                       4



Interests tendered, it will, to the extent necessary,  extend the period of time
during  which  the Offer is open as  provided  above  and will  promptly  notify
Members.

                  (6) A tender of  Interests may be withdrawn at any time before
12:00  midnight,  Eastern time,  January 25, 2008 and, if Interests have not yet
been accepted for purchase by the Company, at any time after February 27, 2008.

                  (7) Members wishing to tender Interests  pursuant to the Offer
should mail a completed  and  executed  Letter of  Transmittal  to the  Transfer
Agent, to the attention of Tender Offer Administrator,  at the address set forth
on page 2 of the Offer, or fax a completed and executed Letter of Transmittal to
the Transfer Agent, also to the attention of Tender Offer Administrator,  at the
fax number set forth on page 2 of the Offer.  The completed and executed  Letter
of Transmittal must be received by the Transfer Agent, either by mail or by fax,
no later than the Expiration Date. The Company  recommends that all documents be
submitted to the Transfer Agent by certified mail, return receipt requested,  or
by facsimile  transmission.  A Member choosing to fax a Letter of Transmittal to
the Transfer Agent must also send or deliver the original completed and executed
Letter of Transmittal to the Transfer Agent promptly thereafter.

                  Any Member  tendering  an  Interest  pursuant to the Offer may
withdraw its tender as described  above in Item 4(a)(6).  To be  effective,  any
notice  of  withdrawal  must be timely  received  by the  Transfer  Agent at the
address or fax  number  set forth on page 2 of the Offer.  A form to use to give
notice of withdrawal  of a tender is available by calling the Transfer  Agent at
the  telephone  number  indicated on page 2 of the Offer.  A tender of Interests
properly  withdrawn will not thereafter be deemed to be tendered for purposes of
the  Offer.  However,  subsequent  to  the  withdrawal  of  tendered  Interests,
Interests may be tendered  again prior to the  Expiration  Date by following the
procedures described above.

                  (8) For  purposes of the Offer,  the Company will be deemed to
have accepted (and thereby purchased)  Interests that are tendered when it gives
written notice to the tendering Member of its election to purchase such Member's
Interest.

                  (9) If more than $1 million of Interests  are duly tendered to
the Company prior to the Expiration  Date and not withdrawn,  the Company may in
its sole  discretion:  (a)  accept  the  additional  Interests  permitted  to be
accepted pursuant to Rule  13e-4(f)(1)(ii)  under the Securities Exchange Act of
1934, as amended (the "1934 Act"); or (b) amend and extend the Offer to increase
the amount of Interests  that the Company is offering to purchase.  In the event
the amount of  Interests  duly  tendered  exceeds  the amount of  Interests  the
Company has offered to purchase  pursuant to the Offer or any amendment  thereof
(including  the  amount of  Interests,  if any,  the  Company  may be willing to
purchase as permitted by Rule  13e-4(f)(1)(ii)  under the 1934 Act), the Company
will accept Interests duly tendered on or before the Expiration Date for payment
on a PRO  RATA  basis  based  on the  aggregate  net  asset  value  of  tendered
Interests.  The Offer may be  extended,  amended or  canceled  in various  other
circumstances described in (5) above.


                                       5



                  (10) The purchase of  Interests pursuant to the Offer may have
the effect of increasing  the  proportionate  interest in the Company of Members
who do not tender Interests.  Members that retain their Interests may be subject
to increased  risks that may possibly result from the reduction in the Company's
aggregate assets resulting from payment for the Interests tendered.  These risks
include the potential for greater  volatility due to decreased  diversification.
However,  the Company  believes that this result is unlikely given the nature of
the Company's  investment  program.  A reduction in the aggregate  assets of the
Company may result in Members that do not tender Interests  bearing higher costs
to the extent that certain  expenses borne by the Company are  relatively  fixed
and may not  decrease  if  assets  decline.  These  effects  may be  reduced  or
eliminated to the extent that additional subscriptions for Interests are made by
new and existing Members on January 2, 2008 and thereafter from time to time.

                  (11) Not Applicable.

                  (12) The  following  discussion  is  a  general summary of the
Federal income tax consequences of the purchase of Interests by the Company from
Members pursuant to the Offer. Members should consult their own tax advisors for
a complete  description of the tax  consequences  to them of a purchase of their
Interests by the Company pursuant to the Offer.

                  In general,  a Member from which an Interest is  purchased  by
the Company will be treated as receiving a distribution  from the Company.  Such
Member  generally will not recognize income or gain as a result of the purchase,
except to the extent (if any) that the amount of  consideration  received by the
Member exceeds such Member's then adjusted tax basis in such Member's  Interest.
A Member's  basis in such  Interest  will be adjusted  for income,  gain or loss
allocated (for tax purposes) to such Member for periods prior to the purchase of
such Interest.  Cash distributed to a Member in excess of the adjusted tax basis
of such  Member's  Interest  is taxable as a capital  gain or  ordinary  income,
depending on the circumstances.  A Member that has its entire Interest purchased
by the Company may generally  recognize a loss,  but only to the extent that the
amount of consideration received from the Company is less than the Member's then
adjusted tax basis in such Member's Interest.

                       (i)   Not Applicable.

                       (ii)  Not Applicable.

                       (iii) Not Applicable.

                       (iv)  Not Applicable.

                       (v)   Not Applicable.

                       (vi)  Not Applicable.

ITEM 5.        PAST CONTRACTS, TRANSACTIONS,  NEGOTIATIONS AND  AGREEMENTS  WITH
               RESPECT TO THE ISSUER'S SECURITIES.

               The Company's LLC Agreement, which was provided to each Member in
advance of  subscribing  for  Interests,  provides that the  Company's  Board of
Managers has the sole discretion to determine  whether the Company will purchase
Interests  from  Members  from time to time  pursuant  to written  tenders.  The
Adviser expects that it will recommend to the Board of Managers that the Company
purchase  Interests from Members  quarterly,  effective as of March 31, June 30,
September 30 and December 31, in accordance with the offering  materials of such
Members.  The Company has previously  offered to purchase Interests from Members
pursuant to written tenders, effective as of December 31, 2007.

               The   Company  is  not  aware  of  any   contract,   arrangement,
understanding or relationship relating,  directly or indirectly,  to this tender
offer  (whether or not  legally  enforceable)  between:  (i) the Company and the
Adviser or any Manager of the Company or any person  controlling  the Company or
controlling the Adviser or any Manager of the Company; and (ii) any person, with
respect to Interests. However, the LLC Agreement provides that the Company shall
be dissolved if the Interest of any Member that has submitted a written request,
in accordance with the terms of the LLC Agreement, to tender its entire Interest
for  purchase  by the Company  has not been  repurchased  within a period of two
years of the request.

ITEM 6.        PURPOSES  OF  THIS  TENDER  OFFER  AND  PLANS OR PROPOSALS OF THE
               ISSUER OR AFFILIATE.


               (a) The purpose of the  Offer  is to provide liquidity to Members
that hold  Interests,  as  contemplated by and in accordance with the procedures
set forth in the LLC Agreement.

               (b)  The   Company   currently   expects   that  it  will  accept
subscriptions  for  Interests as of January 2, 2008 and on the first day of each
month thereafter, but is under no obligation to do so.


               (c) Neither the Company nor the Adviser nor the Board of Managers
has  any  plans  or  proposals  that  relate  to or  would  result  in:  (1) the
acquisition  by any person of  additional  Interests  (other than the  Company's
intention to accept  subscriptions  for Interests on the first day of each month
and from time to time in the discretion of the Company),  or the  disposition of
Interests; (2) an extraordinary transaction, such as a merger, reorganization or
liquidation,  involving  the  Company;  (3) any  material  change in the present
distribution  policy or indebtedness or capitalization  of the Company;  (4) any
change in the  identity of the Adviser or the members of the Board of  Managers,
or in the management of the Company including,  but not limited to, any plans or
proposals  to change the number or the term of members of the Board of Managers,
to fill any existing  vacancy on the Board of Managers or any plans or proposals
to change any material term of the  investment  advisory  arrangements  with the
Adviser,  except as described below; (5) a sale or transfer of a material amount
of assets of the Company (other than as the Board of Managers  determines may be
necessary  or  appropriate  to fund all or a portion of the  purchase  price for
Interests  to be  acquired  pursuant  to the  Offer  or in  connection  with the


                                       7



ordinary portfolio  transactions of the Company);  (6) any other material change
in the Company's structure or business, including any plans or proposals to make
any changes in its fundamental investment policies, as amended, for which a vote
would be  required  by Section 13 of the 1940 Act; or (7) any changes in the LLC
Agreement or other actions that might impede the  acquisition  of control of the
Company by any person. Because Interests are not traded in any market,  Sections
(6), (7) and (8) of Regulation  M-A s.  229.1006 (c) are not  applicable to the
Company.

               On November 28, 2007, the Company's  Board of Managers  appointed
Mr.  Kevin Hunt to replace  Mr.  William J. Landes as Chief  Executive  Officer,
President  and  Principal  Manager of the  Company,  effective as of January 15,
2008.

ITEM 7.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

               (a) The Company  expects  that the purchase  price for  Interests
acquired  pursuant  to the Offer,  which will not exceed $1 million  (unless the
Company elects to purchase a greater  amount),  will be derived from one or more
of the  following  sources:  (i) cash on hand;  (ii) the proceeds of the sale of
and/or  delivery of  securities  and portfolio  assets held by the Company;  and
(iii) possibly  borrowings,  as described in paragraph (b),  below.  The Company
will segregate,  with its custodian, cash or U.S. government securities or other
liquid  securities  equal to the value of the amount  estimated to be paid under
any Notes as described above.

               (b) None of the Company, the Adviser or the Board of Managers has
determined  at this time to  borrow  funds to  purchase  Interests  tendered  in
connection with the Offer. However,  depending on the dollar amount of Interests
tendered and prevailing general economic and market conditions,  the Company, in
its sole  discretion,  may decide to seek to borrow  money to  finance  all or a
portion  of the  purchase  price  for  Interests,  subject  to  compliance  with
applicable  law. If the Company  finances any portion of the  purchase  price in
that  manner,  it will  deposit  assets in a special  custody  account  with its
custodian,  to serve as  collateral  for any  amounts  so  borrowed,  and if the
Company were to fail to repay any such amounts,  the lender would be entitled to
satisfy the Company's  obligations from the collateral  deposited in the special
custody account.  The Company expects that the repayment of any amounts borrowed
will be made from additional funds contributed to the Company by existing and/or
new Members, or from the proceeds of the sale of securities and portfolio assets
held by the Company.

               (c) Not Applicable.

               (d) Not Applicable.

ITEM 8. INTEREST IN SECURITIES OF THE ISSUER.

               (a) Based on October 31, 2007, estimated values, OMUSH owns
$1,104,012.81 in Interests (approximately 8.96% of the outstanding Interests).

               (b) There have been no transactions involving Interests that were
effected during the past 60 days by the Company, the Adviser, any Manager or any
person controlling the Company, the Adviser or any Manager.


                                       8

To the Members of Old Mutual Absolute Return Master Fund, L.L.C.:

               Old Mutual  Absolute  Return Master Fund,  L.L.C.,  a closed-end,
non-diversified,  management  investment company organized as a Delaware limited
liability company (the "Company"), is offering to purchase for cash on the terms
and conditions set forth in this offer to purchase ("Offer to Purchase") and the
related  Letter  of  Transmittal  (which  together  with the  Offer to  Purchase
constitutes  the  "Offer")  up to $1  million  of  Interests  in the  Company or
portions thereof pursuant to tenders by members of the Company  ("Members") at a
price equal to their net asset value as of March 31, 2008,  if the Offer expires
on January 25, 2008, or, if the Offer is extended, approximately one month after
the expiration date of the Offer (in each case, the "Valuation  Date"). (As used
in this Offer,  the term  "Interest" or  "Interests,"  as the context  requires,
shall refer to the  interests in the Company and portions  thereof  representing
beneficial interests in the Company.) If the Company elects to extend the tender
period,  for  the  purpose  of  determining  the  purchase  price  for  tendered
Interests, the net asset value of such Interests will be determined at the close
of business on the Valuation  Date.  This Offer is being made to all Members and
is not  conditioned on any minimum amount of Interests  being  tendered,  but is
subject to certain conditions  described below.  Interests are not traded on any
established   trading  market  and  are  subject  to  strict   restrictions   on
transferability  pursuant to the Company's  Limited  Liability Company Agreement
(the "LLC Agreement"), if applicable.

               Members should  realize that the value of the Interests  tendered
in this Offer  likely  will change  between  October 31, 2007 (the last time net
asset value was  calculated)  and the Valuation  Date.  Members  tendering their
Interests  should also note that they will remain  Members in the Company,  with
respect to the  Interest  tendered  and  accepted  for  purchase by the Company,
through the Valuation Date.  Accordingly,  the value of a tendered Interest will
remain at risk until the Valuation Date,  because of its investment  pursuant to
the Company's investment program.





Old Mutual Absolute Return Master Fund, L.L.C.

               Any tendering Members that wish to obtain the estimated net asset
value of their Interests should contact the Company's  transfer agent, Citi Fund
Services (the "Transfer  Agent"),  at the telephone numbers 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 Offer  should
complete and sign the attached  Letter of Transmittal  and mail or fax it to the
Company in the manner set forth in Section 4 below.

                                    IMPORTANT

               None of the  Company,  its  investment  adviser  or its  Board of
Managers  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 they  choose  to do 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  Company as to whether  Members  should  tender
Interests  pursuant  to the  Offer.  No person has been  authorized  to give any
information or to make any  representations  in connection  with the 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 Company.

               This  transaction  has not been  approved or  disapproved  by the
Securities  and  Exchange  Commission  (the  "SEC") nor has the SEC 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 Offer may be directed to the Transfer Agent.

Old Mutual Absolute Return Master Fund, L.L.C.

                               SUMMARY TERM SHEET

               o  As stated in the Limited Liability Company Agreement (the "LLC
                  Agreement") of Old Mutual Absolute Return Master Fund,  L.L.C.
                  (hereinafter  "we" or the  "Company"),  we will  purchase your
                  limited liability company interests ("Interest" or "Interests"
                  as the  context  requires)  at their net asset value (that is,
                  the  value of the  Company's  assets  minus  its  liabilities,
                  multiplied  by the  proportionate  interest in the Company you
                  desire to  tender).  This  offer to  purchase  Interests  (the
                  "Offer") will remain open until 12:00 midnight,  Eastern time,
                  on  January  25,  2008  unless  the  Offer  is  extended  (the
                  "Expiration Date").

               o  The net asset value of the  Interests  will be  calculated for
                  this  purpose  as of  March  31,  2008  or,  if the  Offer  is
                  extended,  approximately  one month after the Expiration  Date
                  (in each case, the "Valuation Date"). The Company reserves the
                  right  to  adjust  the  Valuation  Date  as a  result  of  any
                  extension of the Offer.  The Company will review the net asset
                  value  calculation of the Interests during the Company's audit
                  for its fiscal year ending March 31,  2008,  which the Company
                  expects  will  be  completed  by the end of May  2008  and the
                  audited  net asset value will be used to  determine  the final
                  amount paid for tendered Interests.

               o  You  may  tender  your  entire  Interest,  a  portion  of your
                  Interest  defined as a specific  dollar  value or a portion of
                  your  Interest  above the  required  minimum  capital  account
                  balance.  If you tender your entire  Interest (or a portion of
                  your Interest) and we purchase that Interest, we will give you
                  a non-interest bearing,  non-transferable promissory note (the
                  "Note")  entitling  you to an  amount  equal to the net  asset
                  value of the Interest  tendered (valued in accordance with the
                  LLC Agreement), determined as of the Valuation Date.

               o  The Note will be  mailed to  you and  will  entitle  you to an
                  initial payment in cash and/or marketable  securities  (valued
                  according to the LLC Agreement)  equal to 97% of the net asset
                  value of the Interest  (the "Initial  Payment")  which will be
                  paid to you within 30 days after the Valuation  Date or, if we
                  have requested withdrawals of capital from any portfolio funds
                  in order to finance the  purchase of  Interests,  ten business
                  days  after we have  received  at least  90% of the  aggregate
                  amount withdrawn from such portfolio funds.

               o  The Note will also entitle you to a  contingent  payment  (the
                  "Contingent  Payment") equal to the excess, if any, of (a) the
                  net asset value of the Interest  tendered as of the  Valuation
                  Date (as it may be adjusted  based upon the next annual  audit
                  of the Company's  financial  statements)  over (b) the Initial
                  Payment.  The Fund will  deposit the  aggregate  amount of the
                  Contingent  Payments  in  a  separate,   non-interest  bearing
                  account. The Contingent Payment will be payable promptly after
                  the completion of the Company's next annual audit.

               o  If  you  tender  only  a  portion of your Interest you will be
                  required  to  maintain a minimum  capital  account  balance of
                  $50,000 (or $25,000,  in the case of certain  Members,  as set
                  forth in the offering materials  provided to the Members).  We
                  reserve the right to purchase  less than the amount you tender
                  if the purchase would cause your capital  account to have less
                  than the required minimum balance.

               o  If  we  accept the tender of your entire Interest or a portion
                  of your Interest,  we will pay you your proceeds from: cash on
                  hand, withdrawals of capital from the portfolio funds in which
                  we have invested,  the proceeds of the sale of and/or delivery
                  of  portfolio   securities  held  by  the  Company  and/or  by
                  borrowing if the Offer is extended  (which we do not intend to
                  do).

               o  Following  this  summary  is  a  formal notice of our offer to
                  repurchase your Interests. Our Offer remains open to you until
                  12:00  midnight,  Eastern  time,  on  January  25,  2008,  the
                  expected  expiration  date of the Offer.  Until that time, you
                  have the right to change your mind and  withdraw any tender of
                  your  Interest.  You will also have the right to withdraw  the
                  tender of your  Interest at any time after  February 27, 2008,
                  assuming   your   Interest  has  not  yet  been  accepted  for
                  repurchase.

               o  If you would like us to repurchase  your Interest or a portion
                  of  your   Interest,   you  should  (i)  mail  the  Letter  of
                  Transmittal,  enclosed with the Offer,  to Citi Fund Services,
                  at 3 Canal Plaza, Ground Floor, Portland, ME 04101, Attention:
                  Tender  Offer  Administrator,  or (ii) fax it to the  Transfer
                  Agent at (207)  879-6206,  so that it is received before 12:00
                  midnight,  Eastern  time,  on January 25, 2008. IF YOU FAX THE
                  LETTER OF TRANSMITTAL,  YOU SHOULD MAIL THE ORIGINAL LETTER OF
                  TRANSMITTAL  TO THE TRANSFER  AGENT  PROMPTLY AFTER YOU FAX IT
                  (ALTHOUGH  THE  ORIGINAL  DOES NOT HAVE TO BE RECEIVED  BEFORE
                  12:00 MIDNIGHT, EASTERN TIME, ON JANUARY 25, 2008).

               o  The  value  of  your Interests will change between October 31,
                  2007 (the last time net asset  value was  calculated)  and the
                  Valuation Date.

               o  If  you  would like to obtain the estimated net asset value of
                  your  Interest,  which we  calculate  monthly,  based upon the
                  information  we receive  from the  managers of the  investment
                  funds in which we invest,  you may contact the Transfer  Agent
                  at (800)  838-0232  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).

               o  If more than $1 million of Interests are duly tendered to  the
                  Company  prior  to  the  Expiration  Date  and  not  withdrawn
                  pursuant  to  Section 5 below,  the  Company  will in its sole
                  discretion   either  (a)  accept  the   additional   Interests
                  permitted  to be  accepted  pursuant  to Rule  13e-4(f)(1)(ii)
                  under the  Securities  Exchange  Act of 1934,  as amended (the
                  "1934 Act"); or (b) amend and extend the Offer to increase the

Old Mutual Absolute Return Master Fund, L.L.C.

                  amount of Interests  that the Company is offering to purchase.
                  In the event the amount of Interests duly tendered exceeds the
                  amount of  Interests  the  Company  has  offered  to  purchase
                  pursuant to the Offer or any amendment thereof  (including the
                  amount of  Interests,  if any,  the  Company may be willing to
                  purchase as permitted by Rule  13e-4(f)(1)(ii)  under the 1934
                  Act),  the Company will accept  Interests  duly tendered on or
                  before  the  Expiration  Date for  payment on a PRO RATA basis
                  based on the aggregate net asset value of tendered Interests.

               o  Please note  that  just  as you have the right to withdraw the
                  tender of an Interest,  we have the right to cancel,  amend or
                  postpone this Offer at any time before 12:00 midnight, Eastern
                  time,  on January 25, 2008.  Also  realize  that  although the
                  Offer expires on January 25, 2008, you will remain a Member of
                  the  Company,  with  respect  to  the  Interest  tendered  and
                  accepted for purchase by the  Company,  through the  Valuation
                  Date.  Accordingly,  the value of your tendered  Interest will
                  remain  at risk  until  the  Valuation  Date,  because  of its
                  investment pursuant to the Company's investment program.

          1.  BACKGROUND AND PURPOSE OF THE OFFER.

          The purpose of this Offer is to provide  liquidity to Members who hold
Interests, as contemplated by and in accordance with the procedures set forth in
the  Company's  LLC  Agreement.  The LLC  Agreement,  which was provided to each
Member in advance  of  subscribing  for  Interests,  provides  that the Board of
Managers  has the  discretion  to determine  whether the Company  will  purchase
Interests from Members from time to time pursuant to written tenders. Larch Lane
Advisors LLC, the  investment  adviser of the Company (the  "Adviser"),  expects
that it will  recommend  to the  Board of  Managers  that the  Company  purchase
Interests from Members  quarterly,  effective as of March 31, June 30, September
30 and December 31, in accordance  with the offering  materials of such Members.
The Company has previously  offered to purchase  Interests from Members pursuant
to written  tenders,  effective  as of December 31,  2007.  Because  there is no
secondary trading market for Interests and transfers of Interests are prohibited
without  prior  approval of the Company,  the Board of Managers has  determined,
after  consideration of various matters,  that the Offer is in the best interest
of Members in order to provide  liquidity for Interests as  contemplated  in the
LLC  Agreement.  Such matters  include,  but are not limited to, the  following:
whether any Members have requested the Company to repurchase  their Interests or
portions thereof;  the liquidity of the Company's  assets;  the investment plans
and working capital requirements of the Company; the relative economies of scale
with  respect  to the  size  of the  Company;  the  history  of the  Company  in
repurchasing  Interests;  the economic condition of the securities markets;  and
the  anticipated tax  consequences  of any proposed  repurchases of Interests or
portions thereof.

          The purchase of Interests pursuant to the Offer may have the effect of
increasing  the  proportionate  interest in the  Company of Members  that do not
tender  Interests.  Members  that  retain  their  Interests  may be  subject  to
increased risks due to the reduction in the Company's aggregate assets resulting
from payment for the Interests  tendered.  These risks include the potential for
greater  volatility  due to  decreased  diversification.  However,  the  Company
believes  that  this  result is  unlikely  given  the  nature  of the  Company's
investment  program.  A  reduction  in the  aggregate  assets of the Company may
result in  Members  that do not tender  Interests  bearing  higher  costs to the



                                      B-6



Old Mutual Absolute Return Master Fund, L.L.C.

extent that certain  expenses borne by the Company are relatively  fixed and may
not decrease if assets  decline.  These  effects may be reduced or eliminated to
the extent  that  additional  subscriptions  for  Interests  are made by new and
existing Members on January 2, 2008 and thereafter from time to time.

          The Company  currently  expects that it will accept  subscriptions for
Interests  as of January 2, 2008 and on the first day of each month  thereafter,
but is under no obligation to do so.

          2. OFFER TO  PURCHASE  AND PRICE.

          Subject to the  conditions of the Offer,  the Company will purchase up
to $1 million of Interests  that are tendered by Members and not  withdrawn  (in
accordance  with  Section 5 below) prior to 12:00  midnight,  Eastern  time,  on
January 25, 2008 or any later date as  corresponds to any extension of the Offer
(in each case, the "Expiration Date"). The Company reserves the right to extend,
amend or cancel the Offer as described  in Sections 3 and 7 below.  The purchase
price of an Interest  tendered  will be its net asset value as of the  Valuation
Date,  payable  as set forth in  Section 6. The  Company  reserves  the right to
adjust the Valuation Date as a result of any extension of the Offer.

          As  of  the  close  of  business  on  October  31,  2007,   there  was
approximately  $12.3  million  outstanding  in  capital of the  Company  held in
Interests (based on the estimated  unaudited net asset value of such Interests).
Members may obtain  monthly  estimated  net asset value  information,  which the
Company  calculates  based upon the information it receives from the managers of
the portfolio  funds in which the Company  invests,  until the expiration of the
Offer,  by contacting the Transfer Agent 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).

          3.  AMOUNT OF TENDER.

          Subject to the limitations  set forth below,  Members may tender their
entire Interest,  a portion of their Interest defined as a specific dollar value
or the portion of their  Interest  above the required  minimum  capital  account
balance, as described below. A Member that tenders for repurchase only a portion
of its Interest will be required to maintain a minimum  capital  account balance
of $50,000  (or  $25,000,  in the case of certain  Members,  as set forth in the
offering materials provided to the Members).  If a Member tenders an amount that
would cause the  Member's  capital  account  balance to fall below the  required
minimum,  the Company  reserves  the right to reduce the amount to be  purchased
from such Member so that the required  minimum balance is maintained.  The Offer
is being made to all Members  and is not  conditioned  on any minimum  amount of
Interests being tendered.

          If the amount of Interests that are properly  tendered pursuant to the
Offer and not withdrawn  pursuant to Section 5 below is less than or equal to $1
million (or such greater amount as the Company may elect to purchase pursuant to
the Offer),  the Company will, on the terms and subject to the conditions of the
Offer,  purchase all of the Interests so tendered  unless the Company  elects to
cancel or amend the Offer,  or postpone  acceptance  of tenders made pursuant to
the Offer,  as provided in Section 7 below. If more than $1 million of Interests
are duly tendered to the Company prior to the Expiration  Date and not withdrawn
pursuant to Section 5 below, the Company will in its sole discretion  either (a)
accept the  additional  Interests  permitted  to be  accepted  pursuant  to Rule
13e-4(f)(1)(ii)  under  the 1934  Act;  or (b)  amend  and  extend  the Offer to
increase  the amount of Interests  that the Company is offering to purchase.  In
the event the amount of Interests  duly tendered  exceed the amount of Interests
the  Company has  offered to  purchase  pursuant  to the Offer or any  amendment
thereof  (including the amount of Interests,  if any, the Company may be willing
to  purchase  as  permitted  by Rule  13e-4(f)(1)(ii)  under the 1934 Act),  the



                                      B-7



Old Mutual Absolute Return Master Fund, L.L.C.

Company will accept Interests duly tendered on or before the Expiration Date for
payment on a PRO RATA basis based on the  aggregate  net asset value of tendered
Interests.  The 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 Offer should mail
a completed and executed  Letter of  Transmittal to the Transfer  Agent,  to the
attention of Tender Offer Administrator,  at the address set forth on page 2, or
fax a completed and executed Letter of Transmittal to the Transfer  Agent,  also
to the attention of Tender Offer  Administrator,  at the fax number set forth on
page 2. The completed and executed Letter of Transmittal must be received by the
Transfer  Agent,  either by mail or by fax, no later than 12:00  midnight on the
Expiration Date.

          The Company recommends that all documents be submitted to the Transfer
Agent  via  certified   mail,   return  receipt   requested,   or  by  facsimile
transmission.  A Member  choosing to fax a Letter of Transmittal to the Transfer
Agent must also send or deliver the original  completed  and executed  Letter of
Transmittal  to the  Transfer  Agent  promptly  thereafter.  Members  wishing to
confirm receipt of a Letter of Transmittal may contact the Transfer Agent at the
address or  telephone  number set forth on page 2. The method of delivery of any
documents  is at the  election  and  complete  risk of the Member  tendering  an
Interest  including,  but not limited to, the failure of the  Transfer  Agent to
receive any Letter of  Transmittal  or other  document  submitted  by  facsimile
transmission.  All questions as to the validity,  form,  eligibility  (including
time of receipt) and acceptance of tenders will be determined by the Company, in
its sole  discretion,  and such  determination  shall be final and binding.  The
Company  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 Company, be unlawful.  The Company also
reserves the absolute  right to waive any of the  conditions of the Offer or any
defect in any tender with respect to any  particular  Interest or any particular
Member,  and the  Company's  interpretation  of the terms and  conditions of the
Offer will be final and binding. Unless waived, any defects or irregularities in
connection  with  tenders  must be cured  within such time as the Company  shall
determine.  Tenders  will not be deemed to have been made  until the  defects or
irregularities  have been cured or waived.  None of the Company,  the Adviser or
the Board of  Managers  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. WITHDRAWAL  RIGHTS.

          Any Member  tendering an Interest  pursuant to this Offer may withdraw
such  tender at any time  prior to or on the  Expiration  Date and,  at any time
after  February  27,  2008,  assuming  such  Member's  Interest has not yet been
accepted for purchase by the Company. To be effective,  any notice of withdrawal
of a tender must be timely  received by the Transfer Agent at the address or the
fax number set forth on page 2. A form to use to give notice of  withdrawal of a
tender is  available  by calling  the  Transfer  Agent at the  telephone  number
indicated on page 2. All questions as to the form and validity  (including  time
of receipt) of notices of withdrawal of a tender will



                                      B-8




Old Mutual Absolute Return Master Fund, L.L.C.

be determined by the Company,  in its sole  discretion,  and such  determination
will be final and binding.  A tender of Interests  properly  withdrawn  will not
thereafter  be  deemed  to be  tendered  for  purposes  of the  Offer.  However,
withdrawn  Interests  may be  tendered  again  prior to the  Expiration  Date by
following the procedures described in Section 4.

          6. PURCHASES AND PAYMENT.

          For purposes of the Offer, the Company will be deemed to have accepted
(and  thereby  purchased)  Interests  that are tendered as, if and when it gives
written  notice  to the  tendering  Member  of its  election  to  purchase  such
Interest.  As  stated in  Section 2 above,  the  purchase  price of an  Interest
tendered by any Member will be the net asset value  thereof as of the  Valuation
Date.  The net asset value will be determined  after all  allocations to capital
accounts of the Member required to be made by the LLC Agreement have been made.


          For Members who tender  their  Interest or a portion  thereof  that is
accepted  for  purchase,  payment  of  the  purchase  price  will  consist  of a
non-interest-bearing  non-transferable  promissory note (the "Note") entitling a
Member to an initial and contingent payment. The Note will entitle the Member to
receive  an  initial  payment  of 97% of the  unaudited  net asset  value of the
Interest  tendered and  accepted  for  purchase by the Company.  Payment of this
amount will be made within one month after the Valuation Date or, if the Company
has requested  withdrawals  of its capital from any portfolio  funds in order to
finance the purchase of  Interests,  no later than ten  business  days after the
Company  has  received at least 90% of the  aggregate  amount  withdrawn  by the
Company  from such  portfolio  funds.  The Note  will  also  entitle a Member to
receive a contingent  payment equal to the excess,  if any, of (a) the net asset
value of the  Interests  tendered and accepted for purchase by the Company as of
the Valuation Date,  determined based on the audited financial statements of the
Company for its fiscal year ending March 31, 2008,  over (b) the Initial Payment
(the "Contingent  Payment").  The Note will be delivered to the tendering Member
in the manner set forth below within ten calendar  days after the  acceptance of
the  Member's  Interest.  The Fund  will  deposit  the  aggregate  amount of the
Contingent Payments in a separate,  non-interest bearing account. The Contingent
Payment  will  be  payable  (in the  manner  set  forth  below)  promptly  after
completion  of the audit of the  financial  statements  of the  Company  for its
fiscal  year.  It is  anticipated  that  the  audit of the  Company's  financial
statements will be completed no later than 60 days after March 31, 2008.

          Although  the Company has  retained the option to pay all or a portion
of the purchase price by distributing marketable securities,  the purchase price
will be paid  entirely  in cash except in the  unlikely  event that the Board of
Managers determines that the distribution of securities is necessary to avoid or
mitigate  any  adverse  effect  of the  Offer on the  remaining  Members  of the
Company.

          The Note pursuant to which a tendering Member will receive the Initial
Payment and Contingent  Payment  (together,  the "Cash  Payment") will be mailed
directly to the tendering Member. Any Cash Payment due pursuant to the Note will
be made  by  wire  transfer  directly  to the  tendering  Member  to an  account
designated by the Member.


                                      B-9



Old Mutual Absolute Return Master Fund, L.L.C.

          The Company  expects that the purchase  price for  Interests  acquired
pursuant  to the Offer,  which will not exceed $1  million,  (unless the Company
elects to purchase a greater amount) will be derived from: (a) cash on hand; (b)
the proceeds of the sale of securities and portfolio assets held by the Company;
and/or (c) possibly  borrowings,  as described below. The Company will segregate
with its custodian cash or U.S. government securities or other liquid securities
equal to the  value of the  amount  estimated  to be paid  under  the  Note,  as
described above. Neither the Company, nor the Board of Managers, nor the Adviser
have determined at this time to borrow funds to purchase  Interests  tendered in
connection with the Offer. However,  depending on the dollar amount of Interests
tendered and prevailing general economic and market conditions,  the Company, in
its sole  discretion,  may decide to finance any portion of the purchase  price,
subject to compliance with applicable law,  through  borrowings.  If the Company
finances  any portion of the  purchase  price in that  manner,  it will  deposit
assets in a special  custody  account  with its  custodian,  SEI  Private  Trust
Company, to serve as collateral for any amounts so borrowed,  and if the Company
were to fail to repay any such amounts,  the lender would be entitled to satisfy
the Company's  obligations from the collateral  deposited in the special custody
account.  The Company expects that the repayment of any amounts borrowed will be
made from  additional  funds  contributed to the Company by existing  and/or new
Members or from the proceeds of the sale of securities and portfolio assets held
by the Company.

          7. CERTAIN CONDITIONS OF THE OFFER.

          The Company  reserves the right, at any time and from time to time, to
extend the period of time during which the Offer is pending by notifying Members
of such extension. The purchase price of an Interest tendered by any Member will
be the net  asset  value  thereof  as of the  Valuation  Date.  During  any such
extension,  all  Interests  previously  tendered and not  withdrawn  will remain
subject to the Offer.  The Company also reserves the right, at any time and from
time to time up to and including  acceptance  of tenders  pursuant to the Offer,
to:  (a)  cancel  the  Offer in the  circumstances  set  forth in the  following
paragraph and in the event of such  cancellation  not to purchase or pay for any
Interests  tendered pursuant to the Offer; (b) amend the Offer; and (c) postpone
the acceptance of Interests.  If the Company determines to amend the Offer or to
postpone the acceptance of Interests tendered, it will, to the extent necessary,
extend the period of time during  which the Offer is open as provided  above and
will promptly notify Members.

          The  Company  may cancel the Offer,  amend the Offer or  postpone  the
acceptance  of tenders made  pursuant to the Offer if: (a) the Company would not
be able to  liquidate  portfolio  securities  in a manner  that is  orderly  and
consistent  with the Company's  investment  objectives  and policies in order to
purchase Interests tendered pursuant to the Offer; (b) there is, in the judgment
of the Board of  Managers,  any (i) legal  action or  proceeding  instituted  or
threatened challenging the Offer or otherwise materially adversely affecting the
Company,   (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 Company,  (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 Company has a material  investment,  (v)  commencement  of war,  significant
increase  in armed  hostilities  or other  international  or  national  calamity
directly  or  indirectly  involving  the United  States  that is material to the

event or condition  that would have a material  adverse effect on the Company or
its Members if Interests  tendered pursuant to the Offer were purchased;  or (c)
the Board of  Managers  determines  that it is not in the best  interest  of the
Company to purchase  Interests pursuant to the Offer.  However,  there can be no
assurance  that the Company will  exercise its right to extend,  amend or cancel
the Offer or to postpone acceptance of tenders pursuant to the Offer.

          8. CERTAIN  INFORMATION  ABOUT THE COMPANY.

          The Company is registered under the Investment Company Act of 1940, as
amended  (the  "1940  Act"),  as  a  closed-end,   non-diversified,   management
investment company. It is organized as a Delaware limited liability company. The
principal  executive office of the Company is located at 800 Westchester Avenue,
S-618,  Rye Brook,  New York 10573 and the telephone  number is (888)  266-2200.
Interests are not traded on any  established  trading  market and are subject to
strict restrictions on transferability pursuant to the LLC Agreement.

          Neither the Company nor the Adviser nor the Board of Managers  has any
plans or proposals that relate to or would result in: (a) the acquisition by any
person of additional  Interests  (other than the  Company's  intention to accept
subscriptions for Interests on the first day of each month and from time to time
in the  discretion  of the Company),  or the  disposition  of Interests;  (b) an
extraordinary  transaction,  such as a merger,  reorganization  or  liquidation,
involving  the  Company;  (c) any  material  change in the present  distribution
policy or indebtedness or capitalization  of the Company;  (d) any change in the
identity  of the  Adviser  or the  members of the Board of  Managers,  or in the
management of the Company including,  but not limited to, any plans or proposals
to change the number or the term of  members of the Board of  Managers,  to fill
any  existing  vacancy on the Board of  Managers  or any plans or  proposals  to
change  any  material  term of the  investment  advisory  arrangements  with the
Adviser,  except as described below; (e) a sale or transfer of a material amount
of assets of the Company (other than as the Board of Managers  determines may be
necessary  or  appropriate  to fund all or a portion of the  purchase  price for
Interests  to be  acquired  pursuant  to the  Offer  or in  connection  with the
ordinary portfolio  transactions of the Company);  (f) any other material change
in the Company's structure or business, including any plans or proposals to make
any changes in its fundamental investment policies, as amended, 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 might impede the  acquisition  of control of the
Company by any person.

          On November 28, 2007,  the Company's  Board of Managers  appointed Mr.
Kevin  Hunt to  replace  Mr.  William  J.  Landes  as Chief  Executive  Officer,
President  and  Principal  Manager of the  Company,  effective as of January 15,
2008.

          Based on October 31, 2007 estimated values,  Old Mutual (US) Holdings,
Inc. owns  $1,104,012.81  in Interests  (approximately  8.96% of the outstanding
Interests).

          To the Company's  knowledge,  no executive officer,  Manager, or other
affiliate  plans to tender,  and the Company  presently has no plans to purchase
the Interest of any executive officer, Manager or other affiliate of the Company
pursuant to the Offer.


                                      B-11



Old Mutual Absolute Return Master Fund, L.L.C.

          There have been no  transactions  involving  the  Interests  that were
effected during the past 60 days by the Company, the Adviser, any Manager or any
person controlling the Company or the Adviser or any Manager.

          9. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

          The following  discussion is a general  summary of the federal  income
tax  consequences  of the  purchase of  Interests  by the Company  from  Members
pursuant to the Offer.  Members  should  consult  their own tax  advisors  for a
complete  description  of the tax  consequences  to them of a purchase  of their
Interests by the Company pursuant to the Offer.

          In  general,  a Member  from which an  Interest  is  purchased  by the
Company  will be treated as  receiving a  distribution  from the  Company.  Such
Member  generally will not recognize income or gain as a result of the purchase,
except to the extent (if any) that the amount of  consideration  received by the
Member exceeds such Member's then adjusted tax basis in such Member's  Interest.
A Member's  basis in the Member's  Interest will be reduced (but not below zero)
by the  amount of  consideration  received  by the  Member  from the  Company in
connection with the purchase of such Interest.  A Member's basis in the Member's
Interest will be adjusted for income,  gain or loss allocated (for tax purposes)
to such  Member  for  periods  prior  to the  purchase  of such  Interest.  Cash
distributed  to a Member in excess of the  adjusted  tax basis of such  Member's
Interest  is  taxable as  capital  gain or  ordinary  income,  depending  on the
circumstances.  A Member that has its entire  Interest  purchased by the Company
may  generally  recognize  a loss,  but only to the  extent  that the  amount of
consideration  received from the Company is less than the Member's then adjusted
tax basis in such Member's Interest.

          10. MISCELLANEOUS.

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

          The Company has filed an Issuer Tender Offer  Statement on Schedule TO
with the Securities and Exchange Commission (the "SEC"),  which includes certain
information  relating  to the  Offer  summarized  herein.  A free  copy  of such
statement may be obtained from the Company by contacting  the Transfer  Agent at
the address and telephone  number set forth on page 2 or from the SEC's internet
web site, http://www.sec.gov.  For a fee, a copy may be obtained from the public
reference office of the SEC at Judiciary Plaza, 100 F Street, N.E.,  Washington,
D.C. 20549.

Ladies and Gentlemen:

               The  undersigned  hereby  tenders to Old Mutual  Absolute  Return
Master Fund, L.L.C. (the "Company"), a closed-end,  non-diversified,  management
investment  company  organized  under  the laws of the  State of  Delaware,  the

the context requires) or portion thereof held by the undersigned,  described and
specified below, on the terms and conditions set forth in the offer to purchase,
dated  December  27,  2007  ("Offer  to  Purchase"),  receipt of which is hereby
acknowledged,  and in this Letter of Transmittal (which together  constitute the
"Offer"). THE TENDER AND THIS LETTER OF TRANSMITTAL ARE SUBJECT TO ALL THE TERMS
AND  CONDITIONS SET FORTH IN THE OFFER TO PURCHASE,  INCLUDING,  BUT NOT LIMITED

BY IT, IN ITS SOLE DISCRETION, NOT TO BE IN THE APPROPRIATE FORM.

               The  undersigned  hereby  sells to the  Company  the  Interest or
portion thereof  tendered hereby pursuant to the Offer.  The undersigned  hereby
warrants that the undersigned has full authority to sell the Interest or portion
thereof  tendered  hereby and that the Company will acquire good title  thereto,

request,  the  undersigned  will  execute and deliver any  additional  documents
necessary to complete the sale in accordance with the terms of the Offer.

               The undersigned  recognizes that under certain  circumstances set
forth in the Offer,  the Company  may not be  required  to  purchase  any of the
Interests in the Company or portions thereof tendered hereby.

               A promissory  note for the  purchase  price will be mailed to the

Dear Member:

          Old Mutual  Absolute  Return Master Fund,  L.L.C.  (the "Company") has
received and accepted for purchase  your tender of a limited  liability  company
interest ("Interest") in the Company.

          Because you have  tendered and the Company has  purchased  your entire
investment,  you have been paid a note (the  "Note").  The Note  entitles you to
receive 97% of the purchase  price based on the  estimated  unaudited  net asset
value of the  Company  as of March 31,  2008 or, if the tender  offer  period is
extended,  approximately  one month after the expiration of the tender offer, in
accordance  with the terms of the tender  offer.  A cash  payment in this amount
will be wire  transferred  to the  account  designated  by you in your Letter of
Transmittal  dated  ____________,  no later  than  April 30,  2008,  unless  the
valuation  date of the  Interests  has changed,  or the Company has  requested a
withdrawal of its capital from the portfolio funds in which it has invested.

          The terms of the Note provide that a contingent  payment  representing
the  balance  of the  purchase  price,  if any,  will be paid to you  after  the
completion of the Company's  fiscal year-end audit for the year ending March 31,
2008 and is subject to fiscal  year-end  audit  adjustment.  This amount will be
paid within ten days after the conclusion of the fiscal  year-end  audit,  or on
such earlier date as the Company's Board of Managers may determine, according to
the terms of the tender offer. We expect the audit to be completed by the end of
May 2008.
