(1) 1-for-1
(2) On March 21, 2005, LB I Group Inc. sold approximately 30.1% of the ownership interest in each of LB Pacific GP, LLC and LB Pacific LP to a third party. The transaction reported is the indirect disposition by LB I Group Inc. of the Subordinated Units by virtue of the allocations of equity interests in LB Pacific GP, LLC and LP Pacific LP. The number of Subordinated Units shown as disposed of is based on applying the decrease in proportionate interest of LB I Group Inc. in LB Pacific LP, directly and indirectly through LB Pacific GP, LLC, to the number of Subordinated Units held by LB Pacific LP.
(3) As a result of the transaction described in footnote 2, LB I Group Inc., Lehman Brothers Holdings Inc. and Lehman Brothers Inc. each may be deemed to have disposed of, indirect beneficial ownership of 786,705 Subordinated Units that are convertible on or after June 30, 2005, 786,705 Subordinated Units that are convertible on or after June 30, 2006, and 1,573,409 Subordinated Units that are convertible on or after June 30, 2007.
(4) These Subordinated Units are convertible into Common Units of the Issuer immediately after the distribution of available cash to partners in respect of any quarter ending on or after June 30, 2005, assuming certain financial tests in the Issuer's partnership agreement have been satisfied.
(5) None.
(6) The allocation of a portion of the aggregate purchase price for the equity interests in LB Pacific LP and LB Pacific GP, LLC to the Subordinated Units was determined based on fair market values.
(7) Each of Lehman Brothers Inc., LB I Group Inc. and Lehman Brothers Holdings Inc. may be deemed to beneficially own all of these Subordinated Units, each of which is based on the indirect proportionate interest of such reporting person, following the reported transactions, in such Subordinated Units by virtue of its direct and indirect equity interest in LB Pacific LP.
(8) The Subordinated Units are held by LB Pacific, LP, which also owns all of the 2% general partner interest in the Issuer. The Subordinated Units may be deemed to be beneficially owned by LB I Group Inc., Lehman Brothers Holdings Inc. and Lehman Brothers Inc. However, LB Pacific GP LLC disclaims beneficial ownership of the Subordinated Units except to the extent of its pecuniary interest therein. See Remark (1). The numbers of Subordinated Units beneficially owned by the reporting persons, as reported herein, is based on the reporting person's indirect proportionate interest, following the transactions reported herein, in the Subordinated Units held by LB Pacific LP.
(9) These Subordinated Units are convertible into Common Units of the Issuer immediately after the distribution of available cash to partners in respect of any quarter ending on or after June 30, 2006, assuming certain financial tests in the Issuer's partnership agreement have been satisfied.
(10) These Subordinated Units are convertible into Common Units of the Issuer immediately after the distribution of available cash to partners in respect of any quarter ending on or after June 30, 2007, assuming certain financial tests in the Issuer's partnership agreement have been satisfied.
(11) The transaction date shown is the date on which the allocations to funds managed by the fund manager reporting persons as described in footnote 12 were closed. The effect of the allocations is that the investment funds acquired directly beneficial ownership of limited partnership interests in LB Pacific, LP and membership interests in LB Pacific GP, LLC, and indirectly beneficial ownership of the Subordinated Units, on a basis economically equivalent to a purchase on March 3, 2005 at the same price paid by LB I Group Inc. on March 3, 2005 for the interests in LB Pacific, LP and LB Pacific GP, LLC. Accordingly, the purchasing funds separately compensated LB I Group Inc. for the financing costs attributable to the time period between March 3, 2005 and the applicable transaction date.
(12) On March 21, 2005, LB I Group Inc. allocated approximately 8.7% of the ownership interest in each of LB Pacific GP, LLC and LB Pacific LP to a fund managed by Lehman Brothers Merchant Banking Associates III L.P. The transaction reported is the indirect disposition by LB I Group Inc. and the indirect acquisition by the fund of the Subordinated Units by virtue of the allocations of equity interests in LB Pacific GP, LLC and LP Pacific LP. The number of Subordinated Units shown as disposed of is based on applying the decrease in proportionate interest of LB I Group Inc. in LB Pacific LP, directly and indirectly through LB Pacific GP, LLC, to the number of Subordinated Units held by LB Pacific LP.
(13) As a result of the transaction described in footnote 12, Lehman Brothers Merchant Banking Associates III L.P. and Lehman Brothers Merchant Banking Associates III LLC each may be deemed to have acquired, and LB I Group Inc. and Lehman Brothers Inc. each may be deemed to have disposed of, indirect beneficial ownership of 226,864 Subordinated Units that are convertible on or after June 30, 2005, 226,864 Subordinated Units that are convertible on or after June 30, 2006, and 453,727 Subordinated Units that are convertible on or after June 30, 2007.
(14) The aggregate purchase price paid by the purchasing investment funds managed by Lehman Brothers Merchant Banking Associates III L.P. for the equity interests in LB Pacific, LP and LB Pacific GP, LLC was $15,500,000, plus $33,933 for financing costs, and an allocation of a portion of the aggregate purchase price to the Subordinated Unit based on estimates of the relative fair market values of assets results in a price of $29.10 per Subordinated Unit that is convertible on or after June 30, 2006 (or $29.13 per Unit including financing costs), $27.60 per Subordinated Unit that is convertible on or after June 30, 2006 (or $27.63 per Unit including financing costs), and $26.70 per Subordinated Unit that is convertible on or after June 30, 2007 (or $26.73 per Unit including financing costs).
(15) Each of Lehman Brothers Inc. and LB I Group Inc. may be deemed to beneficially own 1,602,682 of these Subordinated Units; Lehman Brothers Holdings Inc. may be deemed to beneficially own all of these Subordinated Units; and Lehman Brothers Merchant Banking Associates III L.P. and Lehman Brothers Merchant Banking Associates III LLC each may each be deemed to beneficially own 226,864 of these Subordinated Units, each of which is based on the indirect proportionate interest of such reporting person, following the reported transactions, in such Subordinated Units by virtue of its direct and indirect equity interest in LB Pacific LP.
(16) Each of Lehman Brothers Inc. and LB I Group Inc. may be deemed to beneficially own 3,205,364 of these Subordinated Units; Lehman Brothers Holdings Inc. may be deemed to beneficially own all of these Subordinated Units; and Lehman Brothers Merchant Banking Associates III L.P. and Lehman Brothers Merchant Banking Associates III LLC each may each be deemed to beneficially own 453,727 of these Subordinated Units, each of which is based on the indirect proportionate interest of such reporting person, following the reported transactions, in such Subordinated Units by virtue of its direct and indirect equity interest in LB Pacific LP.
