Item 3.        Source and Amount of Funds or Other Consideration.

               This report relates to the acquisition by Opcap LP of 26,052,966
PIMCO Advisors GP Units in connection with the merger of Oppenheimer Capital
with a subsidiary of PIMCO Advisors (the "Oppenheimer Capital Merger"). The
background of the transaction is as follows:

               On November 4, 1997, PIMCO Advisors acquired the investment
advisory assets of Oppenheimer Group, Inc. ("Opgroup"), including a 32.4%
managing general partner interest in Oppenheimer Capital (a general partnership
in which Opcap LP held a 67.6% interest prior to the Oppenheimer Capital
Merger), the sole one percent general partner interest in Opcap LP, one percent
general partner interests in three subsidiaries of Oppenheimer Capital and the
ownership of Value Advisors LLC, a newly formed limited liability company
holding eight closed-end investment fund management contracts formerly held by
Advantage Advisers, Inc. (the "Opgroup Transaction"). As consideration for these
assets, the Opgroup stockholders received 2,119,608 Class A units of limited
partner interest in PIMCO Advisors (the "PIMCO Advisors Class A LP Units"),
rights (the "Opgroup Exchange Rights") to acquire up to 6,900,000 additional
PIMCO Advisors Class A LP Units (or, after December 31, 1997, the same number of
units of limited partner interest in Opcap LP ("Opcap LP Units")) at $33 1/3
per unit upon exchange of 6% Senior Notes due December 1, 2037 of Opgroup (the
"Opgroup Notes") and rights to require PIMCO Advisors to repurchase some or all
of these units for $25.50 per unit (the "Opgroup Put Rights").

               PIMCO Advisors acquisition of Opgroup's investment advisory
assets in the Opgroup Transaction was accomplished as follows:

                        (i) Immediately prior to the transaction, Opgroup
               redeemed certain shares of its outstanding stock in exchange for
               (A) $244 million in available cash, (B) $150 million in Opgroup
               Notes and (C) an $80 million face amount Certificate of Long-Term
               Indemnity Indebtedness (subject to reduction upon the occurrence
               of certain indemnity obligations with respect to the investment
               management assets), which under certain circumstances converts
               into an equal principal amount of Opgroup Notes. The Opgroup
               Notes are limited in recourse to the assets of Opgroup.

                        (ii) Following the redemption, a newly-formed,
               wholly-owned limited liability company subsidiary of PIMCO
               Advisors merged with and into Opgroup. In the merger, Opgroup
               became a subsidiary of PIMCO Advisors, and the Opgroup
               stockholders received 2,119,608 PIMCO Advisors Class A LP Units,
               the Opgroup Exchange Rights, and the Opgroup Put Rights. The
               Opgroup stockholders also are entitled to certain registration
               rights with respect to these units.


                                       12
<PAGE>   13

                        (iii) Immediately following the merger, Opgroup, then a
               subsidiary of PIMCO Advisors, caused its subsidiary Oppenheimer
               Financial Corp. ("Opfin") to contribute (i) the ownership of
               Value Advisors LLC and the sole one percent general partner
               interest in Opcap LP and then (ii) Opfin's 32.4% managing general
               partner interest in Oppenheimer Capital and the one percent
               general partner interests in three subsidiaries of Oppenheimer
               Capital to Value Advisors LLC (then a subsidiary of PIMCO
               Advisors). In exchange for these contributions, Opfin received
               6,000,000 Class C units of limited partner interest (the "PIMCO
               Advisors Class C LP Units"). Each PIMCO Advisors Class C LP Unit
               is entitled to the same proportionate share of profits, losses
               and distributions as a PIMCO Advisors Class A LP Unit, but with a
               maximum distribution of $3.00 per year, or $0.75 per quarter
               subject to a catch-up on an annual basis. In connection with this
               transaction, Opcap LP adopted an amendment to its partnership
               agreement converting the one percent general partner interest
               into a one-one hundredth of one percent general partner interest,
               with the remaining interest converted into Opcap LP Units. PIMCO
               Advisors then sold the general partner interest in Opcap LP to
               PIMCO Partners, G.P., the general partner of PIMCO Advisors, for
               $80,000. In addition, PIMCO Advisors loaned $35 million to
               Opgroup, and Opgroup used this loan to retire the indebtedness
               owed by Opfin to Opcap LP (the "Opfin Debt").

               On November 30, 1997, Oppenheimer Capital merged with a
transitory limited partnership subsidiary of PIMCO Advisors, with Oppenheimer
Capital surviving (the "Oppenheimer Capital Merger"). As a result of the
Oppenheimer Capital Merger, Oppenheimer Capital became an indirect wholly-owned
subsidiary of PIMCO Advisors, and Opcap LP (the other general partner of
Oppenheimer Capital prior to the Oppenheimer Capital Merger, which held a 67.6%
interest in Oppenheimer Capital), received an aggregate of 25,490,757 PIMCO
Advisors GP Units (the "Merger Units") in exchange for its Oppenheimer Capital
general partner interest and was admitted as a general partner of PIMCO
Advisors. Concurrent with the merger, Opcap LP acquired an additional 562,208
PIMCO Advisors GP Units for $16.7 million in cash (the "Purchased Units"). Also,
in connection with Opcap LP's admission as a general partner of PIMCO Advisors,
PGP transferred one PIMCO Advisors GP Unit to Opcap LP (the "Additional Unit").
On December 1, 1997, a 1.67 for one split of Opcap LP units of limited partner
interest ("Opcap LP Units") was effected, having the effect that each Opcap LP
Unit outstanding after the unit split represents an economic interest in one
PIMCO Advisors GP Unit (after taking account of the 0.3 million PIMCO Advisors
GP Units underlying the general partner interest in the Opcap LP held by PGP).

               Opcap LP's acquisition of the Merger Units, the Purchased Units
and the Additional Unit (the "Event") in connection with the Oppenheimer Capital
Merger triggered the reporting requirements of Section 13 of the Exchange Act,
as amended (the "Exchange Act").


                                       13
<PAGE>   14

Item 4.        Purpose of Transaction.

               (i.) Primary Purpose. The primary purpose of the Event was to
combine the businesses of PIMCO Advisors and Oppenheimer Capital through the
acquisition by PIMCO Advisors of the 67.6% general partner interest in
Oppenheimer Capital not owned by it.

               (ii.) The Restructuring. The general partners of PIMCO Advisors
plan a restructuring of the public ownership of the PIMCO Advisors Class A LP
Units as described below. Due to recent legislation, certain publicly traded
limited partnerships, including PIMCO Advisors and Opcap LP, will be subject to
a tax on their gross income from active businesses after December 31, 1997,
unless their partnership interests cease to be publicly traded by such date. The
limited partner units in both PIMCO Advisors and Opcap LP are currently publicly
traded, and they represent the same economic interest in the business of PIMCO
Advisors. In order to consolidate the public ownership of PIMCO Advisors in one
entity and to prevent PIMCO Advisors from being subject to such a tax, PIMCO
Advisors will effect a restructuring, pursuant to authority granted in the PIMCO
Advisors Partnership Agreement, by causing the contribution on behalf of the
holders of PIMCO Advisors units (the "Public Unitholders"), of all the PIMCO
Advisors units held by Public Unitholders to Opcap LP effective as of December
31, 1997 (the "Restructuring"). In the Restructuring, the Public Unitholders
will receive one Opcap LP unit for each PIMCO Advisors unit contributed on their
behalf. For each Opcap LP Unit outstanding, Opcap LP will hold one underlying
PIMCO Advisors unit. Accordingly, Public Unitholders will continue to hold
indirectly the same economic interest in PIMCO Advisors as they held directly
before the Restructuring. The Restructuring will result in PIMCO Advisors Class
A LP Units ceasing to be publicly held or traded. In connection with the
Restructuring, the PIMCO Advisors Class A Units will be delisted from the New
York Stock Exchange, and will cease being registered under the Exchange Act.
Opcap LP units for which the Public Unitholders' PIMCO Advisors units are
exchanged will continue to be listed on the New York Stock Exchange.

               (iii.) Management of PIMCO Advisors. PIMCO Advisors is managed by
its general partners, PGP and Opcap LP. PGP is the sole general partner of Opcap
LP, and therefore has sole control of PIMCO Advisors. The general partners have
the equal right, power and authority to manage and control the business and
affairs of PIMCO Advisors and to take any action deemed necessary or desirable
by them in connection with the business of PIMCO Advisors. Any difference
arising as to any action connected with the business of PIMCO Advisors, other
than those requiring the unanimous consent of the general partners, is decided
by the general partners holding a majority of the outstanding PIMCO GP Units.

               Each of the following actions require the unanimous consent of
all of the general partners: (i) the constitution of a delegate and the
delegation to such delegate of any of the rights, powers and duties of the
general partners and any revision or revocation of such constitution or
delegation; (ii) any merger or consolidation of PIMCO Advisors with another
business entity in which PIMCO Advisors is not the surviving entity; (iii) any
sale of all or substantially all of PIMCO Advisors assets; (iv) any inccurrence
of indebtedness by PIMCO Advisors or its subsidiaries except in the ordinary
course of business; (v) initiation, consent to or acquiescence 


                                       14
<PAGE>   15

in any Insolvency Event (as defined in the PIMCO Advisors Partnership Agreement)
with respect to PIMCO Advisors; (vi) any other action which would make it
impossible for the general partners to carry on the ordinary course of business
of PIMCO Advisors; (vii) any determination, after the occurrence of an Event of
Withdrawal (as defined in the PIMCO Advisors Partnership Agreement) with respect
to a general partner, to carry on the business of PIMCO Advisors; (viii) any

Item 6.        Contracts, Arrangements, Understandings or Relationships with 
               Respect to Securities of the Issuer.

               (i.) Operating Agreement. PIMCO Advisors and Opcap LP are party
to an Operating Agreement dated November 4, 1997 (the "Operating Agreement")
which, together with the PIMCO Advisors Partnership Agreement, governs the
ongoing relationship of Opcap LP and PIMCO Advisors. Pursuant to the Operating
Agreement, Opcap LP has agreed to take such actions as shall be required from
time to time so as to ensure that the number of outstanding Opcap LP Units is at
all times equal to the number of PIMCO Advisors Units held by Opcap LP and its
subsidiaries which are allocable to the limited partner interests in Opcap LP.
The Operating Agreement provides that upon any issuance of Opcap LP Units, Opcap
LP shall immediately contribute the consideration, if any, received by Opcap LP
for such Opcap LP Units to PIMCO Advisors in exchange for PIMCO Advisors GP
Units equal in number of such Opcap LP Units.

               The Operating Agreement provides that Opcap LP shall, at the
request of PIMCO Advisors from time to time, adopt and maintain one or more unit
incentive plans covering Opcap LP Units or PIMCO Advisors Class A LP Units for
the benefit of individuals providing services to Opcap LP, PIMCO Advisors and
their respective subsidiaries. Awards under the unit incentive plans to
individuals providing services to PIMCO Advisors and its subsidiaries are to be
determined by the PIMCO Advisors unit incentive committee.

               In addition, the Operating Agreement provides that Opcap LP
assumes and agrees to perform the obligations of PIMCO Advisors under: (i) the
PIMCO Advisors unit-based incentive plans (the PIMCO Advisors 1993 Unit Option
Plan and 1996 Unit Incentive Plan (but with regard to options outstanding
immediately after giving effect to the restructuring, only to the extent such
options are exercisable to purchase Opcap LP Units), the awards of which will be
assumed by the 1997 Plan); (ii) the Exchange Right issued by PIMCO Advisors in
the Opgroup Transaction; and (iii) the registration rights agreements to which
PIMCO Advisors is a party.

               The Operating Agreement provides that Opcap LP may not, without
the written consent of PIMCO Advisors, (a) carry on any business except in
connection with or incidental to (i) the performance of its duties as a general
partner under the PIMCO Advisors Partnership Agreement, (ii) the direct or
indirect acquisition, ownership or disposition of PIMCO Advisors units, and
(iii) its governance and existence; (b) merge or consolidate with or into any
other person, or sell or otherwise dispose of all or substantially all of its
assets, or effect a recapitalization with respect to Opcap LP Units, or issue or
agree to issue any equity securities other than Opcap LP Units; or (c) create,
incur, issue, assume, guarantee or otherwise become directly or indirectly
liable, contingently or otherwise, with respect to any indebtedness.

               The Operating Agreement also provides rights for certain holders
of PIMCO Advisors units and rights to exchange their PIMCO Advisors units for
Opcap LP Units, subject to limitations set forth in the PIMCO Advisors
Partnership Agreement. These rights are described below under "Exchange Rights."


                                       21
<PAGE>   22

               (ii.) Exchange Rights. Pursuant to the Operating Agreement, twice
each year, as soon as practicable after financial statements or the preceding
year, or for the first six months of the fiscal year, as the case may be, are
available, Opcap LP shall file a registration statement under the Securities Act
of 1933, as amended (or prepare a prospectus under a continuing registration
statement) covering Opcap LP Units to be issued in exchange for Private Units
(as defined below) (a "Registration Statement"). The Registration Statement
shall cover resales by affiliates of Opcap LP. Upon the effectiveness of the
Registration Statement, Opcap LP shall make an offer to the holders of Private
Units (each, a "Private Unitholder") to acquire some or all of the Private Units
held by them in exchange for an equal number of Opcap LP Units (an "Exchange").
The Operating Agreement defines a "Private Unit" as a PIMCO Advisors unit (i)
designated as a Private Unit in a written certificate executed by PIMCO
Advisors, which designation is not subsequently revoked, (ii) issued pursuant to
a unit incentive plan covering PIMCO Advisors units, or (iii) held by the
obligees under certain indebtedness owned by PGP. Those Private Unitholders who
hold Private Units that are subject to registration rights under the 1994
registration rights agreements will be entitled to exercise such rights with
respect to any Opcap LP Units received pursuant to an exchange of such Private
Units for Opcap LP Units that is permitted under the safe harbor rules and other
unit transfer provisions under the PIMCO Advisors Partnership Agreement.

               The exchange rights described above are subject to limitations
imposed by the general partners pursuant to their authority under the PIMCO
Advisors Partnership Agreement. Under these limitations, which are intended to
allow exchanges pursuant to the exchange rights to qualify under and IRS
regulatory safe harbor for avoiding "publicly traded partnership" tax status for
PIMCO Advisors, certain limitations are imposed on the number of Private Units
that may be exchanged in any one year, with exceptions for certain types of
"block transfers" and other exchanges.

               Those Private Unitholders who hold Private Units that are subject
to lender and 1997 registration rights under the PIMCO Advisors 1994
registration rights agreements will be entitled to exercise such rights with
respect to any Opcap LP Units received pursuant to an exchange of such Private
Units for Opcap LP Units that is permitted under the safe harbor rules and other
unit transfer provisions under the PIMCO Advisors Partnership Agreement.

                          (i)     In accordance with the requirements of
Section 704(c) of the Code and Treasury Regulation Section
1.704-1(b)(2)(iv)(d), any deductions for depreciation, cost recovery or
amortization attributable to Contributed Property shall be determined as if the
adjusted basis of such Contributed Property on the date it was acquired by the
Partnership was equal to the Carrying Value of such Contributed Property. Upon
an adjustment pursuant to Section 7.2(c) to the Carrying Value of any
Partnership Asset subject to depreciation, cost recovery or amortization, any
further deductions for such depreciation, cost recovery or amortization
attributable to such Partnership Asset shall be determined as if the adjusted
basis of such Partnership Asset was equal to the Carrying Value of such
Partnership Asset immediately following such adjustment.

                          (ii)    Any income, gain or loss attributable to the
taxable disposition of any Partnership Asset shall be determined by the
Partnership as if the adjusted basis of such Partnership Asset as of such date
of disposition was equal in amount to the Partnership's Carrying Value with
respect to such Partnership Asset as of such date.

                          (iii)   Subject to the provisions of Treasury
Regulation Section 1.704-1(b)(2)(iv)(m), the amounts of any adjustments to the
bases (or Carrying Values) of Partnership Assets made pursuant to Section 743
of the Code shall not be reflected in Capital Accounts, but the amounts of any
adjustments to the bases (or Carrying Values) of Partnership Assets made
pursuant to Section 734 of the Code as a result of the distribution of
Partnership Assets by the Partnership to a Partner or Assignee shall (A) be
reflected in the Capital Account of the Partner or Assignee receiving such
distribution in the case of a distribution in liquidation of such Partner's or
Assignee's Partnership Interest and (B) otherwise be reflected in Capital
Accounts in the manner in which the unrealized income and gain that is
displaced by such





                                       22
<PAGE>   32

adjustments would have been shared had the Partnership Assets been sold at
their Carrying Values immediately prior to such adjustments.

                          (iv)    The computation of all items of income, gain,
loss and deduction shall be made, as to those items described in Section
705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such
items are not includable in gross income or are neither currently deductible
nor capitalizable for federal income tax purposes. For this purpose, amounts
paid or incurred to organize the Partnership or to promote the sale of
Partnership Interests that are neither deductible nor amortizable under Section
709 of the Code, and deductions for any losses incurred in connection with the
sale or exchange of Partnership Assets disallowed pursuant to Section 267(a)(1)
or 707(b) of the Code, shall be treated as expenditures described in Section
705(a)(2)(B) of the Code.

                 (b)      Generally, a Transferee of a Partnership Interest
will succeed to the Capital Account relating to the Partnership Interest
Transferred. However:

                          (i)      If the Transfer causes a termination of the
Partnership under Section 708(b)(1)(B) of the Code, the Partnership shall be
deemed to have contributed all Partnership Assets and Partnership liabilities
to a new reconstituted partnership in exchange for one hundred percent of the
interests in such reconstituted partnership, and immediately thereafter, the
Partnership shall be deemed to have dissolved and distributed all interests in
the reconstituted partnership to the Partners and Assignees, followed by the
continuation of the business of the Partnership by the reconstituted
partnership. In such event, the Carrying Values of the Partnership Assets shall
be adjusted immediately prior to such deemed distribution pursuant to Section
7.2(d) (and such adjusted Carrying Values shall constitute the fair market
values of such Partnership Assets upon their deemed contribution to the
reconstituted Partnership). The Capital Accounts of such reconstituted
Partnership shall be maintained in accordance with the principles of Section
7.1 and this Section 7.2

                          (ii)    If the Transfer is of LP Units held by a
General Partner, and if immediately prior to such Transfer such General Partner
has a negative Capital Account balance, then the Transferee shall be credited
with a zero balance in its Capital Account relating to such LP Units, and such
General Partner shall retain its negative Capital Account balance.

                 (c)      In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), in connection with either (i) a Contribution (other than
a de minimis amount) by a new or existing Partner or Assignee in consideration
for a Partnership Interest or (ii) a distribution of Partnership Assets (other
than a de minimis amount) in consideration for a Partnership Interest, the
Capital Accounts of all Partners and Assignees and the Carrying Values of all
Partnership Assets may be adjusted (consistent with the provisions hereof)
upwards or downwards to reflect any Unrealized Gain or Unrealized Loss
attributable to each Partnership Asset, as if such Unrealized Gain or
Unrealized Loss had been recognized upon an actual sale of such Partnership
Asset at such time and had been allocated to the Partners and Assignees
pursuant to Sections 8.5 and 8.6. For





                                       23
<PAGE>   33

purposes of determining such Unrealized Gain or Unrealized Loss, the fair
market value of Partnership Assets shall be determined by the General Partners.

                 (d)      In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(e), immediately prior to the actual or deemed distribution of
any Partnership Asset in kind, the Capital Accounts of all Partners and
Assignees and the Carrying Values of such Partnership Asset shall be adjusted
(consistent with the provisions hereof) upward or downward to reflect any
Unrealized Gain or Unrealized Loss attributable to such Partnership Asset as if
such Unrealized Gain or Unrealized Loss had been recognized upon an actual sale
of such Partnership Asset immediately prior to such distribution and had been
allocated to the Partners and Assignees, at such time, pursuant to Sections 8.5
and 8.6. For purposes of determining such Unrealized Gain or Unrealized Loss,
the fair market value of Partnership Assets shall be determined by the General
Partners.


                                  ARTICLE VIII

                         DISTRIBUTIONS AND ALLOCATIONS


         Section 8.1 Cash Distributions During the Interim Period.

         With respect to each fiscal quarter ending on or prior to the end of
the Interim Period, commencing with the fiscal quarter ending December 31, 1994,
the Partnership shall distribute an amount in cash equal to the Distributable
Cash for such quarter. Such distributions shall be made to Unitholders of record
30 days after the last day of each such fiscal quarter, and shall be paid on
Class A Units and Class C Units not more than 45 days, and on Class B Units not
more than 60 days, after the last day of each such fiscal quarter. Such
distributions shall be made in accordance with the following priorities:


                          (i)     First, to such Unitholders holding Class A
Units or Class C Units, pro rata in accordance with their Class A Units and
Class C Units, without regard to whether such Units are Class A Units or Class
C Units, until the cash distributions made pursuant to this clause (i) with
respect to each Class A Unit and Class C Unit equal the Class A Quarterly
Priority Amount;

                          (ii)    Second, to such Unitholders holding Class B
Units, pro rata in accordance with their Class B Units until the cash
distributions made pursuant to this clause (ii) with respect to each Class B
Unit equal the Class B Quarterly Priority Amount; and

                          (iii)   Third, to such Unitholders holding Class A
Units, Class B Units or Class C Units, pro rata in accordance with their Class
A Units, Class B Units and Class C Units, without regard to whether such Units
are Class A Units, Class B Units or Class C Units, until the





                                       24
<PAGE>   34

cash distributions made pursuant to the preceding clauses (i) and (ii) and this
clause (iii) with respect to each Class A Unit, Class B Unit and Class C Unit
equal the Class C Quarterly Cap;

                          (iv)    Fourth, to such Unitholders holding Class A
Units or Class B Units, pro rata in accordance with their Class A Units and
Class B Units, without regard to whether such Units are Class A Units or Class
B Units; provided, however, that the Partnership may withhold distributions to
the holders of Class B Units to protect the distributions in respect of the
Class A Units and Class C Units in future fiscal quarters.

         Section 8.2 Cash Distributions After the Interim Period.

         With respect to each fiscal quarter ending after the end of the Interim
Period, the Partnership shall distribute an amount in cash equal to the
Distributable Cash for such fiscal quarter. Such distributions shall be made to
Unitholders of record 30 days after the last day of each such fiscal quarter,
and shall be paid not more than 60 days after the last day of each such fiscal
quarter. Such distributions shall be made in accordance with the following
priorities:


                          (i)     First, to such Unitholders holding Class A
Units, Class B Units or Class C Units, pro rata in accordance with their Class
A Units, Class B Units and Class C Units, without regard to whether such Units
are Class A Units, Class B Units or Class C Units, until the cash distributions
made pursuant to this clause (i) with respect to each Class A Unit, Class B
Unit and Class C Unit equal the Class C Quarterly Cap;

                          (ii)    Second, to such Unitholders holding Class A
Units or Class B Units, pro rata in accordance with their Class A Units and
Class B Units, without regard to whether such Units are Class A Units or Class
B Units.

         Section 8.3 Special Cash Distributions Prior to Restructuring.

                 (a)      Immediately prior to the effectiveness of the first
Restructuring, the Partnership shall, if the regular quarterly distribution for
the fiscal quarter ending before the effectiveness of the Restructuring has not
been paid, pay such distribution as provided in Section 8.1 if such fiscal
quarter ended on or prior to the end of the Interim Period, and otherwise as
provided in Section 8.2.

                 (b)      Immediately prior to the effectiveness of the first
Restructuring, but after the distribution, if any, required by Section 8.3(a),
the Partnership shall distribute an amount equal to cash on hand of the
Partnership, less cash required for expenses, for capital expenditures, as
reserves or otherwise in the business of the Partnership or any successor to
the business of the Partnership after the Restructuring, as determined by the
General Partners. Such distribution shall be made as provided in Section 8.1 if
such distribution is made during a fiscal





                                       25
<PAGE>   35

quarter ending on or prior to the end of the Interim Period, and otherwise as
provided in Section 8.2.

         Section 8.4 General Rules with Respect to Distributions.

                 (a)      The General Partners are also authorized to
distribute Partnership Assets in kind. Any Partnership Asset distributed in
kind shall be valued at its fair market value on the date of distribution and
shall be distributed in accordance with Sections 8.1and 8.2.  Capital Accounts
and Carrying Values shall be adjusted in accordance with Section 7.2(e).

                 (b)      The General Partners shall specify a Record Date for
any distribution, and any Partnership Assets distributed shall be distributed
to the Unitholders of the relevant class or series as of the Record Date.

                 (c)      Any amount of taxes withheld pursuant to Section
10.4, and any amount of taxes, interest or penalties paid by the Partnership to
any governmental entity, with respect to amounts allocated or distributable to
a Unitholder shall be deemed to be a distribution or payment to such Unitholder
and shall reduce the amount otherwise distributable to such Unitholder pursuant
to this Article VIII.

                 (d)      Distributions made to Unitholders shall be made to
"Unitholders"as defined in Article I without regard to the last sentence of the
definition of "Unitholder".

                 (e)      The Partnership shall not make a distribution to any
Partner on account of its Partnership Interest if such distribution would
violate Section 17-607 of the Delaware Act or other applicable law.

         Section 8.5 Allocations of Income and Loss.

                 (a)      For Capital Account purposes, except as otherwise
provided in Section 8.6, Net Income and Net Loss of the Partnership shall be
determined and allocated as set forth in this Section 8.5, and allocations of
Net Income and Net Loss shall be deemed to be allocations of proportionate
shares of the items of income, gain, loss and deduction from which Net Income
and Net Loss are calculated.

                 (b)      Net Income and Net Loss of the Partnership shall be
determined with respect to each fiscal month of the Partnership's existence,
and allocations of such Net Income and Net Loss with respect to each such month
shall be made annually.

                 (c)      If the Partnership has Net Income for a taxable year,
Net Income for such taxable year shall be treated as earned in those months in
which the Partnership earned Net Income, in proportion to the Net Income earned
by the Partnership in each of such months. Net Income thus treated as earned in
particular months shall be allocated among the Unitholders in





                                       26
<PAGE>   36

the same proportions as any distributions would have been made with respect to
the fiscal quarter in which the relevant month falls if all of the Net Income
treated as earned in such fiscal quarter were distributed to the Unitholders as
provided in Sections 8.1 or 8.2, as the case may be. Although Sections 8.1 and
8.2 require distributions of cash to classes of Unitholders to be determined
with reference to prior distributions of cash, for purposes of making
allocations pursuant to the previous sentence, references in such Sections to
prior distributions of cash should be read to refer to prior allocations of Net
Income pursuant to this Section 8.5(c) with respect to prior fiscal quarters.

                 (d)      If the Partnership has a Net Loss for a taxable year,
such Net Loss shall be treated as incurred in those fiscal months in which the
Partnership incurred a Net Loss, in proportion to the Net Loss incurred by the
Partnership in each of such months. The Net Loss treated as incurred in each
such month shall be allocated (i) first, to the Unitholders having positive
Capital Account balances so as to cause their respective Capital Account
balances to be in (or, if not possible, closer to) the same proportion to each
other as their respective Percentage Interests and then in accordance with
their respective Percentage Interests until all such positive balances have
been eliminated; and (ii) thereafter, any additional Remaining Net Loss shall
be allocated to the General Partners in respect of their GP Units. To the
extent subsequent Net Income of the Partnership does not exceed Net Loss
allocated pursuant to this Section 8.5(d), such Net Income shall be allocated
to the General Partners in respect of their GP Units until such allocated Net
Income equals Net Loss allocated to the General Partners pursuant to Section
8.5(d)(ii), thereafter to the Unitholders in the same proportions and amounts
as Net Loss was allocated pursuant to Section 8.5(c)(i). For purposes of this
Section 8.5(d), the determination of Capital Account balances shall be made
after giving effect to all distributions of cash made with respect to fiscal
quarters or years before the month in question pursuant to Sections 8.1, 8.2
and 8.3.

         Section 8.6 Special Provisions Governing Capital Account Allocations.

                 (a)      In the event that any Partner or Assignee has a
deficit Capital Account at the end of any Partnership fiscal year which is in
excess of such Partner's or Assignee's obligation (including any deemed
obligation under Treasury Regulations or Temporary Treasury Regulations), if
any, to restore an amount to the Partnership, and such excess deficit exists
following the allocations referred to in Sections 8.5(d) and (e), such Partner
or Assignee shall be allocated Net Income in proportion to such remaining
excess deficit amounts.

                 (b)      If any Partner or Assignee unexpectedly receives any
adjustments, allocations or distributions described in Treasury Regulation
Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
1.704-1(b)(2)(ii)(d)(6), Net Income or items of income and gain shall be
specially allocated to such Partner or Assignee in an amount and manner
sufficient to eliminate, to the extent required by the Treasury Regulations, a
deficit in its Capital Account (computed as provided in Treasury Regulation
Section 1.704-1(b)(2)(ii)(d)(3)) as quickly as possible. This Section 8.6(b) is
intended to constitute a "qualified income offset" within the





                                       27
<PAGE>   37

meaning of Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(3) and shall be
interpreted to comply with the requirements of such regulation. Any special
allocations of items of income or gain pursuant to this Section 8.6(b) shall be
taken into account in computing subsequent allocations of Net Income or Net
Loss so that the net amounts of any items subsequently so allocated shall, to
the extent possible, be equal to the net amounts that would have been allocated
to each Partner if such special allocations had not occurred.

                 (c)      In the event there is a net decrease in Minimum Gain
during a Partnership taxable year, the Partners shall be allocated items of
income and gain in accordance with Treasury Regulation Section 1.704-2(f). Any
Partner's share of Minimum Gain shall be determined in accordance with Treasury
Regulation Section 1.704-2(g). This Section 8.6(c) is intended to comply with
the minimum gain chargeback requirement of Treasury Regulation Section 1.704-2
and shall be interpreted and applied in a manner consistent therewith. Any
special allocations of items of income or gain pursuant to this Section 8.6(c)
shall be taken into account in computing subsequent allocations of Net Income
or Net Loss so that the net amounts of any items subsequently so allocated and
the special allocations shall, to the extent possible, be equal to the net
amounts that would have been allocated to each Partner or Assignee if such
special allocations had not occurred.

                 (d)      To the extent required by Treasury Regulation Section
1.704-2(i), any tax items of the Partnership that are attributable to a
non-recourse debt of the Partnership that constitutes "partner non-recourse
debt" as defined in Treasury Regulation Section 1.704-2(b)(4) shall be
allocated in accordance with the provisions of Treasury Regulation Section
1.704-2(i). This Section 8.6(d) is intended to satisfy the requirements of
Treasury Regulation Section 1.704-2(i) (including the partner nonrecourse
minimum gain chargeback requirements) and shall be interpreted and applied in a
manner consistent therewith. Any special allocations pursuant to this Section
8.6(d) shall be taken into account in computing subsequent allocations of Net
Income or Net Loss so that the net amounts of any items subsequently so
allocated and the special allocations shall, to the extent possible, be equal
to the net amounts that would have been allocated to each Partner or Assignee
if such special allocations had not occurred.

                 (e)      The General Partners shall make special allocations
of Net Income or Net Loss or items of income, gain, loss or deduction to GP
Units as may be necessary to permit conversion of such Units to LP Units in
accordance with Section 4.1(b). For purposes of allocating income, gain, loss
or deduction to LP Units that were converted from GP Units for periods
following such conversion, the Units shall be deemed as of the effective date
of such conversion to have been allocated the same amount of income, gain, loss
and deductions and to have received the same distributions as the LP Units
outstanding prior to such conversion.

                 (f)      If and to the extent that any Partner or Assignee is
deemed to recognize income as a result of any transaction between such Partner
or Assignee and the Partnership pursuant to Section 482, Section 483, Sections
1272-1274 or Section 7872 of the Code, or any similar provision now or
hereafter in effect, any corresponding loss or deduction of the





                                       28
<PAGE>   38

Partnership shall be allocated to the Partner or Assignee who was charged with
such income. In addition, if all or part of the deductions claimed by the
Partnership for compensation to its employees is disallowed, the income
attributable to such disallowed deductions will be specially allocated to the
General Partners, and any subsequent deductions related to such compensation
will be specially allocated to the General Partners.

                 (g)      In addition to the other special allocations that the
General Partners may make under this Section 8.6, to preserve uniformity of
Units (subject to the priority distribution rights of certain classes of Units)
the General Partners may make special allocations of Net Income or Net Loss or
items of income, gain, loss or deduction, but only if such allocations would
not have a material adverse effect on the Unitholders (other than the General
Partners) and if they are consistent with the principles of Section 704 of the
Code.

                 (h)      To the extent necessary that the Partnership will not
be treated as a corporation or as an association taxable as a corporation for
federal or state income tax purposes, the interests of the General Partners in
each material item of Partnership income, gain, loss, deduction or credit shall
be equal to at least 1% of each such item at all times during the existence of
the Partnership. If any General Partner receives an allocation under this
Section 8.6(h) that such General Partner would not otherwise have received,
subsequent allocations of Net Income or Net Loss shall, to the extent possible
(and subject to this Section 8.6(h)), be made so that the net amounts of Net
Income or Net Loss allocated to the Partners are the same as they would have
been had allocations not been made pursuant to this Section 8.6(h).

         Section 8.7 Allocations for Tax Purposes.

                 (a)      Except as otherwise provided in this Section 8.7, for
federal income tax purposes each item of income, gain, loss and deduction of
the Partnership shall be allocated among the Partners and Assignees in the same
proportion as items comprising Net Income or Net Loss, as the case may be, are
allocated among the Partners. Credits shall be allocated as provided in
Treasury Regulation Section 1.704-1(b)(4)(ii).

                 (b)      In the case of Contributed Property, items of income,
gain, loss, depreciation, amortization and cost recovery deductions
attributable to such property shall be allocated among the Partners in a manner
consistent with the principles of Section 704(c) of the Code that takes into
account the variation between the Net Value of such property and its adjusted
basis, at the time of contribution, to the extent such allocation reduces
Book-Tax Disparities.

                 (c)      In the case of Adjusted Property, items of income,
gain, loss, depreciation and cost recovery deductions attributable thereto
shall (i) first, be allocated among the Partners and Assignees in a manner
consistent with the principles of Section 704(c) of the Code to take into
account the Unrealized Gain or Unrealized Loss attributable to such property
and the allocation thereof pursuant to Section 8.5(d) or (e) to the extent such
allocation reduces





                                       29
<PAGE>   39

Book-Tax Disparities, and (ii) second, in the event such property was
originally Contributed Property, be allocated among the Partners and Assignees
in a manner consistent with Section 8.7(b).

                 (d)      To the extent permissible under applicable Treasury
Regulations, the amount of any gain from a taxable disposition of property
allocated to (or recognized by) a Partner or Assignee (or its successor in
interest), for federal income tax purposes pursuant to the above provisions
shall be deemed to be Recapture Income to the extent such Partner or Assignee
has been allocated or has claimed any deduction directly or indirectly giving
rise to the treatment of such gain as Recapture Income.

                 (e)      All items of income, gain, loss, deduction and credit
recognized by the Partnership for federal income tax purposes and allocated to
the Partners or Assignees in accordance with the provisions hereof shall be
determined without regard to any adjustment made pursuant to Section 743 of the
Code; provided, however, that such allocations, once made, shall, if an
election under Section 754 of the Code is in effect, be adjusted as necessary
or appropriate to take into account those adjustments permitted by Section 743
of the Code, and any adjustments made pursuant to Section 734 of the Code shall
be allocated to the extent permitted under and in accordance with the rule of
Treasury Regulation Section 1.704-1(b)(2)(iv)(m).

                 (f)      The General Partners shall make special allocations
of Net Income or Net Loss or items of income, gain, loss, deduction or credit
that are consistent with the principles of Section 704(c) of the Code and shall
amend the provisions of this Agreement as appropriate to reflect the proposal
or promulgation of Treasury Regulations under Subchapter K of the Code or
otherwise to cause allocations hereunder to be respected for federal income tax
purposes. The General Partners may adopt and employ such methods and procedures
for (i) the maintenance of book and tax capital accounts, (ii) the
determination and allocation of adjustments under Sections 704(c), 734 and 743
of the Code, (iii) the determination and allocation of Net Income, Net Loss,
taxable income, taxable loss and items thereof under this Agreement and
pursuant to the Code, (iv) the determination of the identities and tax
classification of Unitholders, (v) the provision of tax information and reports
to Partners and Assignees, (vi) the adoption of reasonable conventions and
methods for the valuation of assets and the determination of tax basis, (vii)
the allocation of asset values and tax basis, (viii) conventions for the
determination of cost recovery, depreciation and amortization deductions and
the maintenance of inventories, (ix) the recognition of the Transfer of Units,
and (x) compliance with other tax-related requirements, including without
limitation the use of computer software and filing and reporting procedures
similar to those employed by other publicly-traded partnerships, as they
determine are necessary and appropriate to execute the provisions of this
Agreement, to comply with federal and state tax laws, and to achieve uniformity
and fungibility of Units (subject to the priority distribution rights of Class
A Units. If the General Partners determine, based upon advice of counsel, that
no reasonable allowable convention or other method is available to preserve the
uniformity of Units (subject to the priority distribution rights of certain
classes of Units) or the General Partners so





                                       30
<PAGE>   40

elect, Units may be separately identified as distinct classes to reflect
differences in tax consequences.

                 (g)      Unless otherwise required by the Treasury Regulations
under Section 704(c) of the Code, with respect to property owned by or
contributed to the Partnership, the General Partners shall apply the principles
of Section 704(c) of the Code in accordance with the "traditional method" under
Treasury Regulations Section 1.704-3.

         Section 8.8 Monthly Allocations.

                 (a)      Subject to applicable Treasury Regulations, the
Partnership will treat Unitholders of record at the opening of business on the
first day of a fiscal month as being the only Unitholders with respect to such
Units during such month. If any Unit is Transferred during any month, such
items attributable, under the conventions of Section 8.5, to each Unit for such
month shall be allocated to the holder of such Unit on the first day of such
month. Distributions shall be made to the Unitholders as of the applicable

                 (b)      The General Partners may revise, alter or otherwise
modify such methods of allocation (i) to the extent that they determine that
the application of such methods would result in a substantial mismatching of
the allocation of Net Income or Net Loss attributable to a period and the
distribution of cash attributable to the same period as between the Transferor
and Transferee of the Partnership Interest and/or Unit Transferred that could
be minimized by the application of an alternative tax allocation method, or
(ii) to the extent necessary to conform the Partnership's tax allocations to
the requirements of any regulations issued by the Treasury Department or
rulings of the Internal Revenue Service.

         Section 8.9 Allocations Upon Dissolution.

         If upon dissolution of the Partnership pursuant to Article XVII, and
after taking into account all allocations of Net Income and Net Losses (and
other tax items) under this Article VIII, distributions, if they were to be made
to Unitholders in accordance with their respective Capital Accounts, would
result in unequal distributions on their Units, then (i) gross items of income
and gain (and other tax items) for the taxable year of final distribution, and,
to the extent permitted under Section 761(c) of the Code, gross items of income
and gain (and other tax items) for the immediately preceding taxable year, shall
be allocated first to the Class A Unitholders until the Capital Account balance
allocable to each Class A Unit is equal, (ii) the same procedure shall be
followed with respect to Class B Units until the Capital Account balance
allocable to each Class B Unit is equal, and (iii) the same procedure shall be
followed with respect to Class B Units until the Capital Account balance
allocable to each Class B Unit is equal.

bound by this Agreement upon payment for the Units so Transferred, and such
payment shall constitute a request by such initial Transferee that the records
of the Partnership reflect its admission and the appointment and authorization
of the General Partners as its representatives for the purpose of executing
amendments or restatements of this Agreement and any certificates required to
be filed under the Delaware Law.



                                  ARTICLE XIII

                       WITHDRAWAL OR REMOVAL OF PARTNERS
                                       .

         Section 13.1 Withdrawal or Removal of General Partners.


                 (a)      A General Partner may withdraw from the Partnership
as a General Partner without the approval of any other Partner if it Transfers
all of its GP Units to an Affiliate of such General Partner as provided in
Section 6.2(a), and such Affiliate is admitted as a General Partner as provided
in Section 12.1.

                 (b)      Except as provided in Section 13.1(a), a General
Partner shall not voluntarily withdraw from the Partnership as a General
Partner unless (i) the Partnership receives a Limited Liability Opinion, a Tax
Opinion and an Assignment Opinion and (ii) such withdrawal is approved by
Unitholders holding a majority of the outstanding Units, other than the Units
held by such General Partner and its Affiliates, voting as a single class. If
there is only one General Partner, the General Partner shall call and hold a
meeting of the Unitholders to consider the withdrawal of the General Partner.
Such meeting shall be held no sooner than 180 days after the date of such
notice, and any Unitholder may, by notice to the Partnership at least 120 days
prior to the date of the meeting, propose a successor General Partner. Any
proposed successor General Partner shall be a candidate for successor General
Partner at such meeting only if it is qualified to





                                       41
<PAGE>   51

be a General Partner and has agreed in writing to carry on the business of the
Partnership. If the withdrawal is approved, but no successor General Partner is
Approved by the Unitholders on the first ballot of such meeting, a second
ballot shall be held as soon as practicable thereafter in order to consider the
approval of the candidate that received the most votes in the first ballot, and
if such candidate is not Approved by the Unitholders on the second ballot, the
General Partner shall be entitled to withdraw, and upon such withdrawal the
Partnership shall be dissolved and liquidated pursuant to Article XVII. If a
candidate is Approved by the Unitholders as successor General Partner, it shall
be admitted to the Partnership as the General Partner as provided in Section
12.1 immediately prior to the withdrawal of the Departing General Partner.

                 (c)      A General Partner may be removed as a General Partner
by vote of Unitholders holding 80% or more of the outstanding Units, voting as
a single class. A General Partner may not be removed unless (i) the Partnership
receives a Limited Liability Opinion, a Tax Opinion and an Assignment Opinion
with respect to such removal, and (ii) if such General Partner is the sole
General Partner, a Person qualified to be General Partner, which has agreed in
writing to carry on the business of the Partnership, is Approved by the
Unitholders as successor General Partner. Such Person shall be admitted to the
Partnership as a General Partner as provided in Section 12.1 immediately prior
to the removal of the Departing General Partner.

         Section 13.2 Interest of Departing General Partner.


                 (a)      A Departing General Partner shall become a Limited
Partner, and its GP Units, if any, shall be converted into LP Units pursuant to
Section 4.1(b). At the time of such conversion, the Departing General Partner
shall pay to the Partnership an amount equal to any negative balance in its
Capital Account.

                 (b)      If the Partnership is indebted to the Departing
General Partner at the effective date of its withdrawal or removal for funds
advanced, properties sold or services rendered to the Partnership by the
Departing General Partner, the Partnership shall, within 60 days after such
date, pay to the Departing General Partner the full amount of such
indebtedness;  provided, however, that if the Departing General Partner has
withdrawn as a General Partner in violation of this Agreement, the Partnership
may offset against the amount of such indebtedness any damages resulting from
such breach.

                 (c)      If the Departing General Partner has withdrawn or
been removed as a General Partner in accordance with Section 13.1 without
dissolution of the Partnership, the successor to the Departing General Partner,
or if there is no successor, the remaining General Partners, shall (i) assume
all outstanding obligations incurred by the Departing General Partner as a
General Partner of the Partnership, and (ii) take all such action as shall be
necessary to terminate any guarantees of the Departing General Partner and any
of its Affiliates of any obligations of the Partnership. If for whatever reason
the creditors of the Partnership will not consent to such termination of
guarantees, the successor to the Departing General Partner, or if there is no
successor, the remaining General Partners, shall indemnify the Departing
General





                                       42
<PAGE>   52

Partner for any costs and expenses incurred by the Departing General Partner on
account of such guarantees pursuant to an agreement reasonably satisfactory in
form and substance to the Departing General Partner.


         Section 13.3 Business to Be Carried On After Event of Withdrawal.

         Upon the occurrence of an  Event of Withdrawal, the business of the
Partnership shall be carried on by any remaining or newly-admitted General
Partners.

         Section 13.4 No Withdrawal of Limited Partners.

         A Limited Partner may not withdraw from the Partnership as a Limited
Partner; provided, however, that upon a Transfer of Units by a Limited Partner
in accordance with Section 6.3 and the admission of the Transferee as a Limited
Partner, the Transferor Limited Partner shall cease to be a Limited Partner
with respect to the Units so Transferred.



                                   ARTICLE XIV

                        PARTNERSHIP MEETINGS; AMENDMENTS


         Section 14.1 Partnership Meetings.

         Meetings of Unitholders may be called by the General Partners or the
Liquidator or by Unitholders holding at least 10% of the outstanding Units. Any
Unitholder calling a meeting shall specify the number of Units as to which the
Unitholder is exercising the right to call a meeting, and only those Units shall
be counted for the purpose of determining whether the 10% standard of the
preceding sentence has been met. Unitholders shall call a meeting by delivering
to the Partnership one or more notices in writing stating that the signing
Unitholders wish to call a meeting and indicating the specific purposes for
which the meeting is to be called. Action at the meeting shall be limited to
those matters specified in the notice of the meeting, and no Unitholder may
propose, at such meeting, any other matter to be considered by the Unitholders.
Within 60 days after receipt of such a notice from Unitholders or within such
greater time as may be reasonably necessary for the Partnership to comply with
any statutes, rules, regulations, listing agreements or similar requirements
governing the holding of a meeting or the solicitation of proxies for use at
such a meeting, the Partnership shall send a notice of the meeting to the
Unitholders. A meeting shall be held at a reasonable time and convenient place
determined by the General Partners or the Liquidator, as the case may be, on a
date not more than 60 days after the mailing of notice of the meeting. No action
shall be taken at any meeting unless the Partnership has received a Limited
Liability Opinion, a Tax Opinion and an Assignment Opinion with respect to such
action.





                                       43
<PAGE>   53

         Section 14.2 Record Date.

         The General Partners or the Liquidator, if any, shall set a Record Date
for the determination of the Unitholders entitled to notice of and to vote at a
meeting or adjourned meeting of Unitholders, which shall not be less than 10
days nor more than 60 days before the date of the meeting (unless such
requirement conflicts with any law, rule, regulation, guideline or requirement,
including any requirement of any National Securities Exchange on which the Units
are listed or admitted for trading or any other regulatory agency, in which case
such law, rule, regulation, guideline or requirement shall govern).


         Section 14.3 Notice of Meeting.

         Notice of a meeting called pursuant to Section 14.1 shall be given in
writing either personally or by mail or other means of written communication
addressed to each Unitholder of record as of the close of business on the Record
Date for the meeting at the address of such Unitholder appearing on the books of
the Transfer Agent. An affidavit or certificate of mailing of any notice in
accordance with the provisions of this Section 14.3 executed by an officer of
the Partnership, the Transfer Agent or a mailing organization shall be prima
facie evidence of the giving of notice. If any notice addressed to a Unitholder
at its address is returned to the Partnership by the United States Postal
Service marked to indicate that the United States Postal Service is unable to
deliver it, such notice and any subsequent notices shall be deemed to have been
duly given without further mailing if they are available for the Unitholder at
the principal executive office of the Partnership for a period of one year from
the date of the giving of the notice to all other Unitholders.


         Section 14.4 Adjournment.

         When a meeting is adjourned to another time or place, notice need not
be given of the adjourned meeting and a new Record Date need not be fixed if the
time and place thereof are announced at the meeting at which the adjournment is
taken, unless such adjournment shall be for more than 60 days. At the adjourned
meeting, the Partnership may transact any business that might have been
transacted at the original meeting. If the adjournment is for more than 60 days
or if a new Record Date is fixed for the adjourned meeting, a notice of the
adjourned meeting shall be given in accordance with Section 14.3.


         Section 14.5 Waiver of Notice; Consent to Meeting; Approval of Minutes.

         The transactions of any meeting of Unitholders, however called and
noticed, and wherever held, are as valid as though effected at a meeting duly
held after regular call and notice if a quorum is present either in person or by
proxy and if, either before or after the meeting, each of the Unitholders
entitled to vote who is not present in person or by proxy, signs a written
waiver of notice or a consent to the holding of the meeting or an approval of
the minutes thereof. All waivers, consents and approvals shall be filed with the
Partnership records or made a part of





                                       44
<PAGE>   54

the minutes of the meeting. Attendance of a Unitholder at a meeting shall
constitute a waiver of notice of the meeting, except when the Unitholder
objects, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened; provided,  that
attendance at a meeting shall not be deemed to constitute a waiver of any right
to object to the consideration of matters required to be included in the notice
of the meeting, but not so included, if the objection is expressly made at the
meeting.

         Section 14.6 Quorum and Required Vote.


                 (a)      The presence in person or by proxy of a majority of
the Units entitled to vote shall constitute a quorum at a meeting of
Unitholders; provided, that if a separate vote by certain Unitholders or by a
class or series of Units is required by this Agreement, the presence in person
or by proxy of a majority of Units held by such Unitholders or a majority of
the outstanding Units of such class or series, present in person or by proxy
and entitled to vote, shall constitute a quorum with respect to that vote.

                 (b)      At any meeting of the Unitholders duly called and
held in accordance with this Agreement at which a quorum is present, the
affirmative vote of the majority of Units present in person or by proxy and
entitled to vote, or such different or higher percentage as may be required by
this Agreement, shall be the act of the Unitholders; provided, that if a
separate vote of certain Unitholders or by a class or series of Units is
required by this Agreement, the affirmative vote of the majority of Units held
by such Unitholders or a majority of the outstanding Units or such class or
series, present in person or by proxy and entitled to vote, or such different
or higher percentage as may be required by this Agreement, shall be the act of
such Unitholders or such class or series

                 (c)      The Unitholders present at a duly called or held
meeting at which a quorum is present may continue to transact business until
adjournment, notwithstanding the withdrawal of enough Unitholders to leave less
than a quorum, if any action taken (other than adjournment) is approved by
Unitholders holding the requisite percentage of Units specified in this
Agreement. In the absence of a quorum, any meeting of Unitholders may be
adjourned from time to time by the General Partners or upon the affirmative
vote of Unitholders holding a majority of the Units represented either in
person or by proxy and entitled to vote, but no other business may be
transacted.

         Section 14.7 Conduct of Meeting.

         The General Partners or the Liquidator, if any, shall have the
exclusive right and full power and authority to conduct any meeting of
Unitholders, and shall determine the Persons entitled to vote, the existence of
a quorum, the satisfaction of the requirements of this Article XIV, the conduct
of voting, the validity and effect of any proxies, and the determination of any
controversies, votes or challenges arising in connection with or during the
meeting or voting. The General Partners or the Liquidator, as the case may be,
shall designate an individual to serve as





                                       45
<PAGE>   55

chairman of the meeting, and shall further designate an individual to serve as
secretary and to take the minutes of the meeting, in either case including,
without limitation, a Partner, an employee or agent of a General Partner, or an
officer of the Partnership. All minutes shall be kept with the records of the
Partnership maintained by the General Partners. The General Partners or the
Liquidator, as the case may be, may make such other regulations consistent with
applicable law and this Agreement as they may deem advisable concerning the
conduct of any meeting of the Unitholders, including regulations in regard to
the appointment of proxies, the appointment and duties of inspectors of
election, and the submission and examination of proxies and other evidence of
the right to vote.


         Section 14.8 Action Without a Meeting.


                 (a)      Any action that may be taken at a meeting of the
Unitholders may be taken without a meeting if written approvals setting forth
the action so taken are given by Unitholders holding not less than the minimum
number of Units that would be necessary to take such action at a meeting at
which all the Unitholders were present and voted. Prompt notice of the taking
of an action without a meeting shall be given to the Unitholders who have not
approved such action.

                 (b)      If the General Partners or the Liquidator, if any,
submit an action or actions to the Partners for written approval, the General
Partners or the Liquidator, as the case may be, shall set a Record Date for the
determination of the Unitholders entitled to give or withhold written approval
of such action or actions, which shall not precede the date on which the Record
Date is determined and shall not be more than ten days after such date (unless
such requirement conflicts with any law, rule, regulation, guideline or
requirement, including any requirement of any National Securities Exchange on
which the Units are listed or admitted for trading or any other regulatory
agency, in which case such law, rule, regulation, guideline or requirement
shall govern).

                 (c)      If any Person other than a General Partner or the
Liquidator, if any, submits an action or actions to the Partners for written
approval, the Record Date for the determination of the Unitholders entitled to
give or withhold written approval of such action or actions shall be the date
on which the first duly executed written approval setting forth the action or
actions taken or proposed to be taken is delivered to the Partnership at its
principal office by hand or by registered or certified mail, return receipt
requested (unless such requirement conflicts with any law, rule, regulation,
guideline or requirement, including any requirement of any National Securities
Exchange on which the Units are listed or admitted for trading or any other
regulatory agency, in which case such law, rule, regulation, guideline or
requirement shall govern).

                 (d)      No written approval shall be effective unless (i)
such written approval sets forth the action or actions taken or proposed to be
taken, and is delivered to the Partnership within 90 days after the Record Date
for the determination of the Unitholders entitled to give or





                                       46
<PAGE>   56

withhold written approval of such action or actions and (ii) the Partnership
receives a Limited Liability Opinion and a Tax Opinion with respect to such
action or actions.

         Section 14.9 Voting and Approval Rights.


                 (a)      Unless otherwise specified in this Agreement,
Unitholders shall have one vote for each Unit held by them.

                 (b)      Only Unitholders who are Unitholders on the Record
Date determined pursuant to Section 14.2 shall be entitled to notice of, or to
vote at, a meeting of Unitholders. Only Unitholders who are Unitholders on the
Record Date determined pursuant to Section 14.8 shall be entitled to notice of,
or to give or withhold written approval of, any action for which written
approvals are solicited.

                 (c)      With respect to Units that are held for a Person's
account by another Person (such as a broker, dealer, bank, trust company or
clearing corporation, or an agent of any of the foregoing), in whose name such
Units are registered, such other Person shall, in exercising any voting or
approval rights in respect of such Units on any matter, vote such Units or give
or withhold written approval with respect to such Units at the direction of the
Person on whose behalf such other Person is holding such Units, and the
Partnership shall be entitled to assume it is so acting without further
inquiry.

                 (d)      Each Unitholder entitled to vote at a meeting of
Unitholders or to give or withhold written approval of any action may authorize
another Person to act for such Unitholder by proxy. A duly executed proxy shall
be irrevocable if it states that it is irrevocable and if, and only so long as,
it is coupled with an interest sufficient in law to support an irrevocable
power. A proxy may be made irrevocable regardless of whether the interest with
which it is coupled is an interest in the Unit itself or an interest in the
Partnership generally.

         Section 14.10  Amendments to Be Adopted Solely by the General Partners.

                 The General Partners, without the approval of any Limited
Partner, may amend any provision of this Agreement to reflect:


                          (i)     a change in the name of the Partnership or
the location of the principal place of business of the Partnership;

                          (ii)    the admission, substitution, withdrawal or
removal of Partners in accordance with this Agreement;

                          (iii)   a change that the General Partners determine
is appropriate in order to qualify the Partnership as a limited partnership or
a partnership in which the Limited Partners have limited liability under the
laws of any state or to ensure that the Partnership will not be





                                       47
<PAGE>   57

treated as a corporation or as an association taxable as a corporation for
federal income tax purposes;

                          (iv)    a change that the General Partners determine:
(A) does not adversely affect the holders of any class or series of Units in
any material respect, (B) is appropriate in order to satisfy any requirement,
condition or guideline contained in any federal or state statute or any rule,
regulation, requirement, condition or guideline of any federal or state agency,
(C) is appropriate in order to facilitate the listing or trading of the Units
on or otherwise to comply with any rule, regulation, requirement, condition or
guideline of any National Securities Exchange, or (D) is necessary in order to
effect the purposes of this Agreement, or to cure or otherwise correct any
ambiguity, error or omission in any provision of this Agreement;

                          (v)      the designations, preferences and relative
participating, optional or other special rights, powers and duties of any newly
created class or series of Units;

                          (vi)    a change that the General Partners determine
is appropriate in connection with the creation or issuance of any class or
series of Units, other Equity Securities, or other Partnership securities; or

                          (vii)   a change that the General Partners determine
is appropriate in connection with any action taken pursuant to Article XVI.

         Section 14.11 Amendment Procedures.


                 (a)      All amendments to this Agreement, except those
described in Section 14.10, shall be adopted as follows:

                          (i)     Any such amendment shall be proposed by the
General Partners.

                          (ii)    Any such amendment proposed by the General
Partners shall be effective upon its approval by Unitholders holding a majority
of the outstanding Units, voting as a single class; provided, however, that if
(A) the proposed amendment would materially and adversely affect the rights or
preferences of holders of any class or series of Units or other Partnership
Interests, it must also be approved by Unaffiliated Holders holding a majority
of the outstanding Units of such class or series, or a majority in interest of
such Partnership Interests, as the case may be; or (B) the proposed amendment
would change the percentage of Units or other Partnership Interests required to
take any action, it must also be approved by Partners holding at least the
percentage of Units or other Partnership Interests which would be changed by
the proposed amendment.

                 (b)      The General Partners shall notify all Unitholders
upon final approval or disapproval of any amendment proposed by the General
Partners.

                                    ARTICLE XV

                      INDEMNIFICATION AND RELATED MATTERS


         Section 15.1 Indemnification.


                 (a)      The Partnership shall indemnify each Indemnitee and
hold it harmless from and against any and all losses, claims, damages,
liabilities, expenses (including legal fees and expenses), judgments, fines,
settlements and other amounts, whether joint or several (collectively
"Expenses"), arising from, based upon or incurred in connection with any and
all claims, demands, actions, suits or proceedings, civil, criminal,
administrative or investigative, in which the Indemnitee may be involved, or
threatened to be involved, as a party or otherwise, by reason of its status as
an Indemnitee (collectively "Proceedings"), if the Indemnitee acted or failed
to act in good faith and in a manner it reasonably believed to be in, or not
opposed to, the best interests of the Partnership and, with respect to any
criminal proceeding, had no reasonable cause to believe its conduct was
unlawful. The termination of any Proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere, or its equivalent, shall not, of
itself, create a presumption that the Indemnitee acted in a manner contrary to
that specified in the preceding sentence; provided, however, that neither
Thomson nor any of its Affiliates shall be entitled to indemnification
hereunder to the extent that such Person shall be entitled to indemnity under
Section 11.2(a) of the Purchase and Option Agreement dated as of July 24, 1990
by and among Thomson, Thomson McKinnon Inc., a Delaware corporation, Thomson
McKinnon Holdings Inc., a Delaware corporation, Thomson McKinnon Securities
Inc., a Delaware corporation, Thomson McKinnon Asset Management Inc., a
Delaware corporation, Thomson McKinnon Fund Distributors Inc., a Delaware
corporation, and the Partnership.

                 (b)      Excise taxes assessed on an Indemnitee with respect
to an employee benefit plan are Expenses, and any action or failure to act by
such Indemnitee in a manner it reasonably believed to be in, or not opposed to,
the best interests of such plan shall be conclusively deemed to be in, or not
opposed to, the best interests of the Partnership.

         Section 15.2 Indemnification Agreements.

                 The Partnership may enter into an indemnification agreement
with any Indemnitee, which agreement may include, without limitation, some or
all of the following provisions:


                          (i)     that such Indemnitee shall be indemnified as
provided in Section 15.1;

                          (ii)    that if such Person is successful, on the
merits or otherwise, in any Proceeding, it shall be indemnified against all
Expenses actually and reasonably incurred by it or on its behalf in connection
with any Proceeding; that if such Indemnitee is not wholly successful in such
Proceeding but is successful, on the merits or otherwise, as to one or more but
less than





                                       49
<PAGE>   59

all claims, issues or matters in such Proceeding, the Partnership shall
indemnify such Person against all Expenses actually and reasonably incurred by
it or on its behalf in connection with each successfully resolved claim, issue
or matter; and that, for these purposes, and without limitation, the
termination of any claim, issue or matter in such Proceeding by dismissal with
or without prejudice, shall be deemed to be a successful result as to such
claim, issue or matter;

                          (iii)   that the Partnership shall from time to time
advance all Expenses actually and reasonably incurred by or on behalf of such
Indemnitee in connection with any Proceeding, and that each such advance shall
be made  within 20 days after the receipt by the Partnership of a statement
listing Expenses incurred by such Person since the date of the last statement;

                          (iv)    that such Indemnitee shall be presumed to be
entitled to indemnification under such agreement if such Person has properly
submitted a request for indemnification and that the Partnership shall have the
burden of proof to overcome that presumption; and

                          (v)     that if the Person empowered or selected to
determine whether such Indemnitee is entitled to indemnification shall not have
made such determination within a stated period, such Indemnitee shall be
entitled to such indemnification, with such exceptions as may be provided in
such agreement.

         Section 15.3 Indemnification Procedures.

         Except as otherwise provided in any agreement for indemnification
entered into pursuant to Section 15.2:


                          (i)     If an Indemnitee receives notice of any
Proceeding with respect to which the Indemnitee may be entitled to
indemnification under Section 15.1 or such agreement, the Indemnitee shall
promptly give notice to the Partnership of such Proceeding. To the extent that
delay in giving such notice, or failure to give such notice, materially
prejudices the Partnership, the Indemnitee shall not be entitled to
indemnification.

                          (ii)    The Partnership shall from time to time
advance all Expenses actually and reasonably incurred by or on behalf of an
Indemnitee in connection with any Proceeding, upon receipt by the Partnership
of an undertaking by or on behalf of the Indemnitee to repay such advances if
it shall be determined that the Indemnitee is not entitled to be indemnified
under Section 15.1 or such agreement.

                          (iii)   The Partnership may assume the defense of any
Proceeding, with counsel reasonably acceptable to the Indemnitee, by giving
notice to the Indemnitee (a "Defense Notice") of the Partnership's election to
do so. In the event that the Partnership so elects to assume the defense of a
Proceeding, the Partnership will not be liable to the Indemnitee for any





                                       50
<PAGE>   60

attorney's fees or expenses incurred by the Indemnitee with respect to the
defense of such Proceeding after the date of the Indemnitee's receipt of the
Defense Notice, provided that:

                                  (A)      The Indemnitee shall continue to
have the right to employ counsel in any such Proceeding at the Indemnitee's own
expense; and

                                  (B)      If (1) the employment of counsel by
the Indemnitee has previously been authorized in writing by the Partnership, or
(2) the Partnership shall have reasonably concluded, and shall have given
notice to the Indemnitee, that there may be a conflict of interest between the
Partnership and the Indemnitee in the conduct of such defense, or (3) the
Partnership shall not, in fact, have employed counsel to assume the defense of
such Proceeding, then the fees and expenses of the Indemnitee's counsel shall
be paid by the Partnership in accordance with Section 15.1 or such agreement.

                          (iv)    The Partnership may, without the consent of
the Indemnitee, settle any claim in any Proceeding for which it is obligated to
provide indemnification under Section 15.1 or such agreement, and, as a
condition to the Indemnitee's receipt of such indemnification, the Indemnitee
shall take all such actions required to cooperate in effecting such settlement;
provided, however, that the Partnership shall not settle any claim in any
manner that would impose any penalty or limitation on the Indemnitee without
the Indemnitee's written consent (which may not be unreasonably withheld or
delayed).

         Section 15.4 Insurance.

         The Partnership may purchase and maintain insurance for the benefit of
one or more Indemnitees against any Expenses incurred by them, regardless of
whether the Partnership would have the power to indemnify such Indemnitees
against such Expenses under this Agreement.


         Section 15.5 Source of Payment.

         Any indemnification under this Article XV shall be paid solely out of
any insurance purchased pursuant to Section 15.4, or Partnership Assets; and the
General Partners, Limited Partners and Assignees, and their Affiliates, shall
have no liability for any such indemnification.


         Section 15.6 Scope of Indemnification.

         The indemnification provided by Section 15.1 (i) shall be in addition
to any other rights to which an Indemnitee may be entitled under any agreement,
pursuant to any vote of the Unitholders, as a matter of law or otherwise, (ii)
shall continue as to an Indemnitee which has ceased to serve in a capacity for
which the Indemnitee is entitled to indemnification, (iii) shall inure to the
benefit of the heirs, successors, assigns, administrators and personal
representatives of the Indemnitee, and (iv) shall not be deemed to create any
right to indemnification for the benefit of any other Persons.

         Section 15.7 Effect of Amendments.

         No amendment of this Agreement shall limit or otherwise adversely
affect the right of any Indemnitee to indemnification for any act, or failure to
act, which occurred prior to the adoption and effectiveness of the amendment


         Section 15.8 Limitations on Liability of Indemnitees.

                 (a)      The General Partners shall not be liable to the
Partnership or any Partner or Assignee for any action or failure to act on the
part of any Delegate or any committee, subcommittee or officer appointed by
such Delegate, so long as the General Partners appointed such Delegate in good
faith and with reasonable care. Neither a Delegate nor its members, if any,
shall be liable to the Partnership or any Partner or Assignee for any action or
failure to act on the part of any committee, subcommittee or officer appointed
by such Delegate in good faith and with reasonable care.

                 (b)      An Indemnitee shall not be liable to the Partnership
or any Partner or Assignee for breach of fiduciary duty (including breach of
any duty of care or any duty of loyalty) to the Partnership or any Partner or
Assignee unless it is proved by clear and convincing evidence that the
Indemnitee's action or failure to act was undertaken with deliberate intent to
cause injury to the Partnership or was undertaken with reckless disregard for
the best interests of the Partnership.

                 (c)      An Indemnitee may rely upon and shall be protected
and shall incur no liability in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, debenture or other paper or document believed by
it to be genuine and to have been signed or presented by the proper party or
parties. An Indemnitee shall not be liable to the Partnership, any Partner or
Assignee or any other Indemnitee for, and shall be protected in, acting or
refraining from acting, in good faith reliance on the provisions of this
Agreement, and the good faith exercise of any of the powers or rights granted
to an Indemnitee by this Agreement or pursuant to the delegation of power and
authority permitted by this Agreement, shall not constitute a breach of
fiduciary duty to the Partnership, any Partner or Assignee or any other
Indemnitee.

                 (d)      An Indemnitee may consult with legal counsel,
accountants, appraisers, management consultants, investment bankers and other
consultants and advisers selected by it, and any opinion of any such Person as
to matters that such Indemnitee reasonably believes to be within such Person's
professional or expert competence shall be full and complete authorization and
protection in respect to any action taken or suffered or omitted in good faith
and in accordance with such opinion.

                 (e)      In making a determination pursuant to this Agreement,
the General Partners or their Delegates shall take into account such factors as
they consider to be appropriate





                                       52
<PAGE>   62

in the circumstances and shall have no duty or obligation to take any other
factors into account. If any such determination is to be made in "good faith,"
or under another express standard, the General Partners or their Delegates
shall act under such express standard and shall not be subject to any other or
different standards.

                 (f)      If any transaction contemplated by this Agreement is
required to be "fair" to the Partnership, the fairness of such transaction
shall be determined in context with all similar or related transactions and
with all other transactions and relationships among the Persons involved and
their respective Affiliates.


                                   ARTICLE XVI

                                  RESTRUCTURING


         Section 16.1 Power of General Partners to Effect a Restructuring.


                 (a)      If at any time the General Partners determine that as
a result of (i) the enactment (or imminent enactment) of any legislation, (ii)
the publication of any temporary or final regulation by the United States
Department of the Treasury or any ruling by the Internal Revenue Service, (iii)
a judicial decision, or (iv) otherwise (including, without limitation, the
expiration of the period provided under Section 10211(c) of the Revenue Act of
1987, Pub. L. 100-203, as amended by Section 2004(f)(2) of the Technical and
Miscellaneous Revenue Act of 1988, Pub. L. 100-647, during which certain
partnerships may be exempt from the treatment applicable to "publicly traded
partnerships" under Section 7704 of the Code, but not including the General
Partners' voluntary adoption of tax accounting methods or the use of special
allocations which are not required for federal income tax purposes), there is a
substantial risk of an Adverse Partnership Tax Event or a Tax Realization
Event, then the General Partners may take any and all actions that the General
Partners deem appropriate  to accomplish one or more Restructurings. Such
actions authorized pursuant to this Section 16.1(a) include, but are not
limited to:

                          (i)     The creation of one or more Business Entities
controlled by the General Partners, Affiliates of the General Partners or
Affiliates of the Partnership.

                          (ii)    The transfer of all or any part of the
business of the Partnership or the Partnership Assets to one or more existing
or newly-created Business Entities  in exchange for interests in such Business
Entities, which interests may be subject to substantial restrictions on
transfer.

                          (iii)   The initiation of exchange or redemption
transactions which will permit and may automatically effect, without the
consent of any Limited Partner, the exchange of some or all outstanding LP
Units for interests in one or more existing or newly-created Business





                                       53
<PAGE>   63
Entities which hold, directly or indirectly, interests in all or any part of
the business of the Partnership or the Partnership Assets.

                          (iv)    The imposition of substantial restrictions on
the transferability of some or all of the LP Units (or interests in one or more
Successor Entities) for both limited and extended periods of time, which
restrictions may provide for damages (including forfeiture) for attempted
Transfer in violation of such restrictions.

                          (v)     Causing the Partnership and any one or more
Successor Entities to enter into agreements governing their relationships
following the Restructuring, on terms and conditions determined by the General
Partners, including without limitation agreements providing for (A) the
issuance and sale by a Successor Entity of its securities and the contribution
of the proceeds of such issuance and sale to the Partnership, in exchange for
Units or other Partnership securities; (B) the acquisition by a Successor
Entity of businesses or assets and the contribution of such businesses or
assets to the Partnership in exchange for Units; (C) the adoption by a
Successor Entity of one or more employee benefit plans involving the issuance
of its securities, the assumption by such Successor Entity of the outstanding
employee benefit plans of the Partnership, and contribution of the proceeds of
issuance and sale of securities under any employee benefit plans of such
Successor Entity to the Partnership, in exchange for Units; and (D) the
exchange of outstanding Units for securities of a Successor Entity upon request
by the holders of such Units, the registration of such securities under federal
and state securities laws in connection with a public offering, and the
concomitant listing of such securities on a National Securities Exchange.

                 (b)      Without limiting the power and authority of the
General Partners provided in this Section 16.1 to effect one or more
Restructurings at any future time, unless the General Partners determine that
an Adverse Tax Consequence would otherwise occur prior to January 1, 1998, no
Restructuring may be effected that will, prior to November 30, 1997, (i)
restrict the transferability of LP Units held by the Public Unitholders, (ii)
cause an Adverse Partnership Tax Event, or (iii) restrict the ability of
Nonpublic Unitholders to convert LP Units into interests in a Successor Entity.
In addition, the General Partners may not, in effecting a Restructuring,
subject any Limited Partner to liability to Partnership creditors without such
Limited Partner's consent.

                 (c)      The power and authority of the General Partners to
effect (or not to effect) one or more Restructurings (including, without
limitation, an Incorporation Restructuring as provided in Section 16.2) was a
bargained-for and material condition of the willingness of the General Partners
and their Affiliates to enter into the Partnership Agreement. The power and
authority of the General Partners to effect (or not to effect) one or more
Restructurings includes the power and authority to effect one or more
Restructurings that result in benefits to one or more Partners or their
Affiliates (including without limitation the General Partners or their
Affiliates) that are not enjoyed by all Partners, and that may result in
disadvantageous consequences to one or more Partners that are not suffered by
all Partners or their Affiliates (including without limitation the General
Partners or their Affiliates). No Limited Partner shall have any cause of





                                       54
<PAGE>   64

action against, or right to receive any compensation from, the Partnership, the
General Partners or their Affiliates or any other Limited Partner or its
Affiliates, as a result of or in respect of (i) any Restructuring or the
disparate effects thereof on any one or more Partners, (ii) the failure of the
General Partners to effect any one or more Restructurings, or (iii) the General
Partners'  determination to effect a particular Restructuring or Restructurings
instead of any other Restructuring or Restructurings, unless it is proved by
clear and convincing evidence that the action or failure to act of the General
Partners involved an act or omission undertaken with deliberate intent to cause
injury to the Partnership or was undertaken with reckless disregard for the
best interests of the Partnership.

         Section 16.2 Incorporation Restructuring.

         Without in any manner limiting or otherwise restricting the power and
authority of the General Partners to effect one or more Restructurings as
provided in Section 16.1, the General Partners are authorized to effect a
Restructuring (the "Incorporation Restructuring") as follows:


                          (i)     If the General Partners determine to effect
an Incorporation Restructuring, they shall deliver to the Transfer Agent
written notice (the"Incorporation Notice") of the election and shall cause the
Transfer Agent to mail a copy of the Incorporation Notice to all Unitholders at
least 30 days prior to the effective date of the proposed Incorporation
Restructuring (the"Effective Date"). The Incorporation Notice also shall be
published at least once in all editions of a daily newspaper of national
circulation printed in the English language. The Incorporation Notice shall
specify the Effective Date and the number of shares of common stock
(the"Exchange Shares") that shall be issued in exchange for each surrendered
Unit by the corporation (the"Restructuring Corporation") formed or otherwise
utilized by the General Partners to effect the Incorporation Restructuring. Any
such Incorporation Notice mailed to a Unitholder at its address as reflected in
the records of the Transfer Agent shall be conclusively presumed to have been
given regardless of whether the Unitholder receives such notice.

                          (ii)    The General Partners shall cause the
Restructuring Corporation to be formed under the laws of the State of Delaware.
The Restructuring Corporation shall take all requisite actions and effect all
requisite filings and applications so that its common stock shall be listed on
or admitted to trading on the National Securities Exchange on which the Class A
LP Units are then listed or admitted to trading, or on another National
Securities Exchange as deemed appropriate by the General Partners.

                          (iii)   Prior to the Effective Date, the Public
Unitholders shall surrender the Certificates for all of the Units held by them,
and any Nonpublic Unitholder may surrender the Certificates for any or all of
the Units held by it, at such office or offices of the Transfer Agent for the
Class A LP Units as such Transfer Agent may specify, or as may be required by
any National Security Exchange on which the Class A LP Units are listed or
admitted to trading.

<PAGE>   65
                          (iv)    Prior to the Effective Date, the
Restructuring Corporation shall deposit with the Transfer Agent for the Class A
LP Units certificates evidencing sufficient Exchange Shares for issuance in
exchange for (A) all Units held by the Public Unitholders, and (B) all Units
surrendered for exchange by Nonpublic Unitholders.

                          (v)     From and after the Effective Date, (A) all
rights of the Public Unitholders under this Agreement and the Delaware Act
shall cease and terminate, (B) all rights of the Nonpublic Unitholders under
this Agreement and the Delaware Act, to the extent of the Units surrendered by
them, shall cease and terminate, (C) all Units held by Public Unitholders and
all Units surrendered by Nonpublic Unitholders shall be deemed to have been
transferred to the Restructuring Corporation on the books and records of the
Partnership, and (D) the Restructuring Corporation shall be deemed to be the
holder of all such Units from and after the Effective Date for all purposes of
this Agreement.

                          (vi)    As soon as practicable after the Effective
Date, the Transfer Agent for the Class A LP Units shall deliver to the
Unitholders which surrendered Certificates for Units certificates evidencing
the Exchange Shares to be issued to them in exchange for such Certificates

                          (vii)   For a period of six years following the
Effective Date, the Transfer Agent for the Class A LP Units shall continue to
hold the Exchange Shares deposited with it pursuant to clause (iv) and not
delivered in exchange for Certificates, and shall receive, hold in trust and
invest and reinvest all dividends and distributions in respect of such Exchange
Shares. Such Transfer Agent shall, from such dividends and distributions and
the income, if any, therefrom, pay all taxes payable with respect to such
dividends, distributions and income, and all costs and expenses reasonably
incurred by such Transfer Agent with respect to the receipt, holding in trust
and investment and reinvestment of such dividends, distributions and income.
All such dividends, distributions, income, costs and expenses shall be
allocated pro rata to such Exchange Shares.

                          (viii)  At any time during the six years following
the Effective Date, any Public Unitholder which failed to surrender one or more
Certificates pursuant to clause (iii) (each, a "Heldover Certificate"), may
surrender such Certificate to the Transfer Agent for the Class A LP Units, and
upon such surrender such Transfer Agent shall deliver to such Public Unitholder
a certificate evidencing the Exchange Shares deliverable in exchange for such
Certificate plus the amount of the dividends, distributions and income, less
the amount of the costs and expenses, allocated to such Exchange Shares
pursuant to clause (vii). At the close of business on the last day of such
six-year period, such Transfer Agent shall deliver to the Restructuring
Corporation the Exchange Shares, if any, then held by such Transfer Agent,
together with the amount of the dividends, distributions and income, less the
amount of the costs and expenses, allocated to such Exchange Shares pursuant to
clause (vii).

<PAGE>   66
                          (ix)    In connection with and as an integral part of
the Incorporation Restructuring, the General Partners shall have the power and
authority to take such actions as they deem appropriate  to cause the Units to
cease, effective as of the Effective Date, to be either (A) traded on an
established securities market or (B) readily tradable on a secondary market or
the substantial equivalent thereof, as such terms are interpreted and applied
for purposes of Section 7704(b) of the Code. The General Partners shall also
have the power and authority to take any other actions they deem appropriate to
avoid the classification of the Partnership, from and after the Effective Date,
as a publicly traded partnership for purposes of Section 7704 of the Code.

                          (x)     The General Partners shall have the power and
authority to prescribe and effectuate such procedures and rules as they deem
appropriate to implement the Incorporation Restructuring.

         Section 16.3 Consent to Actions Taken in Connection with Restructuring.

         Each of the Limited Partners approves, ratifies and confirms the
execution, delivery and performance by the General Partners of all documents and
instruments, and the taking of all actions and the doing of all things, deemed
appropriate or necessary by the General Partners in connection with any
Restructuring pursuant to this Article XVI, and agrees that the General Partners
are authorized to execute, deliver and perform such documents and instruments,
and to take such actions and do such things, without the approval of the Limited
Partners.

                                  ARTICLE XVII

                          DISSOLUTION AND LIQUIDATION


         Section 17.1 Dissolution.

         The Partnership shall be dissolved and its affairs shall be wound up
upon:


                          (i)     the expiration of its term as provided in
Section 2.5;

                          (ii)    the written determination by the General
Partners that projected future revenues of the Partnership will be insufficient
to enable payment of projected Partnership costs and expenses or, if
sufficient, will be such that continued operation of the Partnership is not in
the best interests of the Partners;

                          (iii)   the written election of the General Partners
to dissolve the Partnership following the occurrence of an Adverse Partnership
Tax Event;





                                       57
<PAGE>   67
                          (iv)    the written election of the General Partners
to dissolve the Partnership, which is approved by Unitholders holding a
majority of the outstanding Units held by Persons other than the General
Partners and their Affiliates, voting as a single class;

                          (v)     the sale of all or substantially all of the
Partnership Assets, other than in connection with a Restructuring;

                          (vi)    the written consent of all of the Partners;

                          (vii)   the occurrence of an Event of Withdrawal,
unless (A) the remaining General Partners carry on the business of the
Partnership, or (B) within 90 days after such Event of Withdrawal, not less
than a majority in interest of the remaining Partners agree in writing to
continue the business of the Partnership and to the appointment, effective as
of the date of such Event of Withdrawal, of one or more additional General
Partners if necessary or desired, and the Partnership receives a Limited
Liability Opinion, a Tax Opinion and an Assignment Opinion with respect to such
continuation: or

                          (viii)  entry of a decree of dissolution under the
Delaware Act.

         Section 17.2 Reconstitution.

         Within 180 days following an Event of Withdrawal that results in the
dissolution of the Partnership, a majority in interest of the remaining Partners
may agree in writing to reconstitute and continue the business of the
Partnership by forming a Reconstituted Partnership on the same terms as are set
forth in this Agreement and to appoint one or more general partners of the
Reconstituted Partnership; provided, however, that no such agreement shall be
effective unless the Partnership has received a Limited Liability Opinion, a Tax
Opinion and an Assignment Opinion with respect to such reconstitution and
continuance. If such an agreement is duly and timely made, all of the Limited
Partners of the Partnership shall continue as limited partners of the
Reconstituted Partnership.


         Section 17.3 Liquidator; Liquidation and Distribution.


                 (a)      Upon dissolution of the Partnership, unless the
Partnership is reconstituted pursuant to Section 17.2, the remaining General
Partners, if any, or if there is no remaining General Partner, the Former
General Partner, if any, whose withdrawal as a General Partner pursuant to
Section 13.1(b) resulted in the dissolution, or if there is no such Former
General Partner, a liquidator or liquidating committee Approved by the
Unitholders, shall be the Liquidator. The Liquidator (if not a General Partner)
shall be entitled to receive such compensation for its services as may be
Approved by the Unitholders. The Liquidator shall agree not to resign at any
time without 15 days' prior written notice and (if not a General Partner or
Former General Partner) may be removed at any time, with or without cause, by
notice of removal Approved by the Unitholders. Upon resignation or removal of
the Liquidator, a





                                       58
<PAGE>   68

successor Liquidator (who shall have and succeed to all rights, powers and
duties of the original Liquidator) shall within 30 days thereafter be Approved
by the Unitholders.

                 (b)      Upon dissolution of the Partnership and until the
filing of a Certificate of Cancellation, the Liquidator may, in the name of and
for and on behalf of the Partnership, prosecute and defend suits, whether
civil, criminal or administrative, gradually settle and close the business of
the Partnership, dispose of and convey the Partnership Assets, discharge or
make reasonable provision for all Partnership liabilities, and distribute to
the Partners any remaining Partnership Assets, all without affecting the
liability of the Limited Partners and without imposing the liability of a
general partner on the Liquidator (if not a General Partner). A reasonable time
shall be allowed for the winding up of the Partnership so as to minimize any
losses otherwise attendant upon such winding up.

                 (c)      Upon the winding up of the Partnership, the
Partnership Assets shall be distributed in the following order of priority,
unless otherwise provided by law:

                          (i)     to creditors of the Partnership, including
Partners and Assignees who are creditors, to the extent otherwise permitted by
law, in satisfaction of Partnership liabilities (whether by payment or the
making of reasonable provision for payment) other than liabilities for which
reasonable provision for payment has been made and liabilities for
distributions to Partners and former Partners pursuant to Section 8.1 or 8.3
with respect to fiscal quarters ending before the dissolution of the
Partnership;

                          (ii)    to the creation of a reserve of cash or other
Partnership Assets for contingent liabilities in an amount, if any, determined
by the Liquidator;

                          (iii)   to Partners and former Partners in
satisfaction of liabilities for distributions pursuant to Section 8.1 or 8.2
with respect to fiscal quarters ending before the dissolution of the
Partnership; and

                          (iv)    to the Unitholders in accordance with their
respective Capital Accounts.

                 (d)      If upon dissolution of the Partnership the Liquidator
determines that immediate liquidation of any or all of the Partnership Assets
would be impracticable or would cause undue loss to the Partners, the
Liquidator may defer for a reasonable time the liquidation of any such
Partnership Assets except those necessary to satisfy the liabilities of the
Partnership to its creditors, and may distribute to the Unitholders, in lieu of
cash, as tenants in common and in accordance with the provisions of Section
17.3(c), undivided interests in such Partnership Assets. Any such distribution
in kind shall be subject to such conditions relating to the management and
disposition of the Partnership Assets so distributed as may be determined by
the Liquidator and to any agreements governing the operation of such
Partnership Assets. The Liquidator shall determine the fair market value of any
Partnership Assets distributed in kind.

<PAGE>   69
                 (e)      After dissolution of the Partnership, upon demand by
the Liquidator, (i) each General Partner, if any, shall contribute to the
Partnership cash in an amount equal to any negative balance in its Capital
Account, and (ii) each Former General Partner, if any, shall pay to the
Partnership cash in an amount equal to any negative balance in its Capital
Account as of the date it became a Former General Partner, less the amount of
any cash paid to the Partnership by such Former General Partner after such date

submit its calculations of the amount required to be paid pursuant to this

<PAGE>   7


3(d), any Person has a right to be indemnified under both this Agreement and the
Merger Agreement (or both this Agreement and the CIBC Agreement) with respect to
any Loss, such Person's indemnification right with respect to such Loss shall be
governed exclusively by this Agreement.

                (e) Tax Matters Are Not Covered Hereby. Notwithstanding anything

complete copy of any written communication, and an accurate and complete written
summary of any oral communication, so received by it or its affiliates. The
failure of the Indemnified Party timely to forward such notification in
accordance with the immediately preceding sentence shall not relieve the
Indemnifying Party of its obligation to pay such Loss, except to the extent that
the failure timely to forward such notification materially prejudices the
ability

Acquisition Agreement.

                  (2) The words "hereof", "herein", and "hereunder" and words of
similar import, when used in this Agreement, shall refer to this Agreement as a
whole and not to any particular provision of this Agreement.


                                        8

                  (3) The terms defined in the singular shall have a comparable
meaning when used in the plural, and vice versa.

      2.    CERTAIN OPERATING CONVENTIONS AND PROCEDURES.

            (a) Termination of Taxable Years. For U.S. federal income Tax
purposes, (i) the taxable year of each member of the Holdings Subgroup shall end
as of the close of the Acquisition Date, but (ii) the taxable year of each
member of the Opgroup Subgroup shall not end as of the close of the Merger Date.

            (b) Allocation of Straddle Period Tax Liability and Procedures. The
allocation of any Tax Liability between the portion of any Straddle Period
ending on the Acquisition Date or the Merger Date, as the case may be, and the
portion of such Straddle Period after such date shall be made by means of a
closing of the books and records of the members of the Holdings Subgroup as of
the close of the Acquisition Date and/or the Opgroup Subgroup as of the close of
the Merger Date, as the case may be, in each case as if a taxable period ended
as of the close of such date; provided, however, that exemptions, allowances or
deductions that are calculated on an annual basis (including, but not limited
to, depreciation and amortization deductions) shall be allocated between the
period ending on such date and the period after such date in the proportion
which the number of days in each such period bears to the total number of days
in the Straddle Period.

            (c) Allocation of Income from Flowthrough Entities.

                  (1) CIBC and the Authorized Representative shall take all
actions necessary to allocate items of income, gain, loss, deduction and credit
of any partnership or "flowthrough" entity, in which any member of the Holdings
Subgroup owns an equity interest immediately after the Acquisition for the
taxable period that includes the Acquisition Date, between the Holdings Subgroup
and the CIBC Post-Acquisition Group as if the taxable period of such flowthrough
entities ended as of the close of the Acquisition Date. As promptly as possible
after the end of the fiscal quarter during which the Acquisition occurs, CIBC
shall cause any such partnership or flowthrough entity to deliver to the
Authorized Representative a pro forma Schedule K-1 showing the allocable shares
of partnership items attributable to the equity interests held by any members of
the Holdings Subgroup for the portion of the taxable period ended as of the
close of the Acquisition Date. The Authorized Representative shall have the
right to review and approve such Schedules K-1 (and any amendments thereto),
which approval shall not unreasonably be withheld.


                                        9

<PAGE>   10

                  (2) OGI and the Authorized Representative shall take all
actions necessary to allocate items of income, gain, loss, deduction and credit
of Opcap and Opcap LP (and any other partnership or "flowthrough" entity in
which any member of the Opgroup Subgroup owns an equity interest immediately
prior to the Merger) for the taxable period that includes the Merger Date
between the Opgroup Subgroup and the OGI Post-Merger Group as if the taxable
period of such flowthrough entities ended as of the close of the Merger Date. As
promptly as possible after the end of the fiscal quarter during which the Merger
occurs, OGI shall cause both Opcap and Opcap LP (and any other such partnership
or flowthrough entity) to deliver to the Authorized Representative a pro forma
Schedule K-1 showing the allowable shares of partnership items attributable to
the equity interests held by any members of the Opgroup Subgroup for the portion
of the taxable period ended as of the close of the Merger Date. The Authorized
Representative shall have the right to review and approve such Schedules K-1
(and any amendments thereto), which approval shall not unreasonably be withheld.

            (d) The Authorized Representative.

                 (1) Prior to the Acquisition Date, Opgroup shall appoint one or
more individuals to serve as the Authorized Representative hereunder. Each of
the parties hereto shall take all actions necessary (including, without
limitation, those set forth in Section 8(d) hereof) to provide the Authorized
Representative with the requisite authority to carry out each of its prescribed
functions hereunder.

                  (2) CIBC and PIMCO LP shall each permit the Authorized
Representative, if otherwise serving as an employee of it or of one of its
affiliates, to serve as the Authorized Representative hereunder and to utilize
the services of those individuals otherwise reporting to the Authorized
Representative. In addition, the Authorized Representative shall be authorized
to retain the services of such outside accountants and/or attorneys to assist in
the preparation of the requisite Tax Returns and in the handling of any Tax
Proceedings and, except or otherwise provided in Section 8 hereof, to pay
reasonable fees and other charges for such services.

     3.    FILING OF TAX RETURNS; PAYMENT OF TAXES.

           (a) Tax Returns Required to Be Filed Prior to Acquisition Date.
Opgroup shall prepare and file or cause to be filed all Tax Returns of Opgroup,
any member of the Opgroup Consolidated Group and any Foreign Subsidiary of any
member of the Opgroup Consolidated Group required to be filed (after giving
effect to any valid extension of time in which to make such filings) prior to
the Acquisition Date


                                       10

<PAGE>   11

and shall pay or cause to be paid all Taxes shown to be due and payable on such
Tax Returns.

            (b) Tax Returns for Pre-Acquisition and/or Pre-Merger Taxable
Periods, Combined Returns.

                  (1) Subject to the joint participation requirements of Section
3(b)(3) hereof, the Authorized Representative shall prepare or cause to be
prepared, for Pre-Acquisition Taxable Periods and for Pre-Merger Taxable
Periods, (A) all required Combined Returns, (B) all other required consolidated,
combined or unitary Tax Returns that include one or more members of the Opgroup
Consolidated Group and (C) all other Tax Returns required to be filed on a
separate return basis by any member of the Opgroup Consolidated Group or any
Foreign Subsidiary thereof, in each case, which Tax Returns are not required to
be (after giving effect to any valid extensions), and are not, filed on or prior
to the Acquisition Date or the Merger Date, as the case may be. The books and
records of Opgroup and each of its Subsidiaries will be maintained, and the
federal, state and other income Tax Returns of each such corporation will be
filed, so as to properly reflect the operations of each such corporation through
the end of the Acquisition Date and/or the Merger Date.

                  (2) Subject to the joint participation requirements of Section
3(b)(3) hereof, the Authorized Representative shall prepare or cause to be
prepared all required Combined Returns which cover a Straddle Period. The books
and records of Opgroup and each of its Subsidiaries will be maintained, and the
federal, state and other income Tax Returns of each such corporation will be
filed, so as to properly reflect the operations of each such corporation through
the end of the relevant Straddle Period.

                  (3) (i) To the extent any Pre-Acquisition Taxable Period or
Pre-Merger Taxable Period is included on a Combined Return that is required to
be filed after the Acquisition Date and whether or not such Combined Return
covers a taxable period that is a Straddle Period, the Authorized Representative
shall permit each of CIBC and OGI, if it elects to do so, to jointly participate
with the Authorized Representative in the preparation of such Combined Return.
To the extent any Tax Return for a Pre-Acquisition Taxable Period or Pre-Merger
Taxable Period that is not a Combined Return is required to be filed after the
Acquisition Date (A) by Holdings and/or any member of the Holdings Subgroup, the
Authorized Representative shall permit CIBC, if it so elects to do so or (B) by
Opgroup and/or any member of the Opgroup Subgroup, the Authorized Representative
shall permit OGI, if it elects to do so, to jointly participate with the
Authorized Representative in the preparation of such


                                       11

<PAGE>   12

Tax Return. Such joint participation shall be conducted in good faith and shall
include, but not be limited to, participation by CIBC and/or OGI, as the case
may be, in all material aspects of the Tax Return preparation; provided,
however, that CIBC or OGI, as the case may be, shall have primary responsibility
for that portion of any Tax Return that covers the post-Acquisition or
post-Merger portion of any Straddle Period except that, if an item reported on
the post-Merger portion of a Combined Return for a Straddle Period would have
been reported on a Tax Return of a member of the Holdings Subgroup, had such
member remained a member of the Opgroup Consolidated Group, but is instead
reported by a member of the OGI Post-Merger Group by reason of Section 381 of
the Code or similar provisions of state or local law (a "Section 381
attribute"), CIBC shall have primary responsibility for the preparation of that
portion of such Tax Return with respect to such item; and provided further,
however, that the Authorized Representative shall have responsibility for
overall coordination of such joint participation process. In each case, CIBC
and/or OGI also shall be provided with a copy of each such Tax Return at least
20 days before the due date for its filing. OGI shall also be provided
concurrently with each Combined Return a statement setting forth in reasonable
detail a calculation of the portion, if any, of the Taxes shown to be due on
such Combined Return which is attributable to any member of the OGI Post-Merger
Group after the Merger Date pursuant to Section 2(b) hereof (the "OGI
Post-Merger Tax Amount").

                        (ii) Each of CIBC and OGI shall have the right to
consult with the Authorized Representative regarding any calculations or
positions taken on the Tax Returns of which they were entitled to participate in
the preparation and, irrespective of whether such joint participation was
elected, to review and approve (such approval not to be unreasonably withheld)
each such Tax Return for 10 business days following its receipt thereof;
provided, however, that, except as provided in subsection (iii) below, CIBC or
OGI shall be deemed to have unreasonably withheld its approval of such Tax
Return unless, as the basis for withholding such approval, the position deals
with an issue arising solely in the post-Acquisition or post-Merger portion of
any Straddle Period included on a Combined Return (in which event, assuming the
existence of a reasonable basis (within the meaning of Section 6662 of the Code)
therefor, CIBC or OGI, as the case may be, may control the decision as to the
appropriate position with respect thereto) or CIBC or OGI demonstrates, by
providing to the Authorized Representative an opinion of counsel reasonably
acceptable to the Authorized Representative or of a "Big Six" accounting firm to
such effect, that substantial authority (within the meaning of Section 6662 of
the Code) does not exist for a position taken on such Tax Return. The failure of
CIBC or OGI to propose any changes to any such Tax Return within such 10
business day period shall be deemed to constitute CIBC's or OGI's approval
thereof.


                                       12

<PAGE>   13

                        (iii) If, however, CIBC and/or OGI propose that the
Authorized Representative change a proposed position on a Combined Return or
another Tax Return that reflects a Tax Liability of at least $100,000, in each
case that is required to be filed after the Acquisition Date, and the Authorized
Representative cannot demonstrate, by providing to CIBC and/or OGI, as the case
may be, an opinion of counsel reasonably acceptable to CIBC and/or OGI, as the
case may be, or of a "Big Six" accounting firm to such effect, that the
Authorized Representative's proposed position is more likely than not to be
sustained if challenged by the relevant Governmental Authority, if the
Authorized Representative does not change such Tax Return to reflect such
proposed change, and if the issue does not involve a matter which otherwise is
an Excluded Liability, an amount of cash shall be retained in the Tax Payment
Account equal to the amount by which the Tax Liability with respect to all such
Tax Returns, if prepared in a manner that reflected such proposed changes on all
such Tax Returns, would have exceeded by more than $1 million, in the aggregate,
the liability reflected on such Tax Returns as finally filed by the Authorized
Representative. Such amounts shall be distributed from time to time to the
Seller Trust after the expiration of the statute of limitations for the taxable
periods with respect to which the Tax Returns giving rise to the retention of
such amounts relate.

                        (iv) Subject to Section 3(e) hereof, the Authorized
Representative shall (A) file or cause to be filed all Tax Returns to which this
Section 3(b) applies and (B) shall pay or cause to be paid from the Tax Payment
Account all Taxes shown on such Tax Returns to be due and payable, including the
portion of such Taxes attributable to the OGI Post-Merger Tax Amount (which
amount shall be timely deposited into the Tax Payment Account by OGI).

            (c) Tax Returns for Post-Acquisition and Post-Merger Taxable
Periods.

                  (1) CIBC shall be responsible for (i) preparing and filing or
causing to be prepared and filed all Tax Returns required to be filed by any
member of the Holdings Subgroup or any Foreign Subsidiary thereof for any
Post-Acquisition Taxable Period and (ii) paying any Tax Liability due with
respect to such Tax Returns.

                  (2) OGI shall be responsible for (i) preparing and filing or
causing to be prepared and filed all Tax Returns required to be filed by any
member of the Opgroup, Subgroup or any Foreign Subsidiary thereof for any
Post-Merger Taxable Period and (ii) paying any Tax Liability due with respect to
such Tax Returns.

            (d) Non-Combined Tax Returns for Straddle Periods.

                  (1) The Authorized Representative shall prepare, and CIBC
shall file or cause to be filed (except to the extent provided in Section
3(d)(1)(i) below, in the form and manner so prepared by the Authorized
Representative), all Tax Returns (other than a Combined Return) of or which
include any member of the Holdings Subgroup or any Foreign Subsidiary thereof
for a Straddle Period. The Authorized Representative shall provide CIBC with
each such Tax Return at least 20 days prior to the due date for filing thereof,
together with a statement setting forth in reasonable detail a calculation of
the portion of the Taxes shown to be due on such Tax Return which is allocable
to the Holdings Subgroup through the Acquisition Date pursuant to Section 2(b)
hereof (the "Holdings Subgroup Tax Amount").

                        (i) CIBC shall have the right to review and approve
(which approval shall not be unreasonably withheld) each such Tax Return for 10
days following receipt thereof; provided, however, that CIBC shall be deemed to
have unreasonably withheld its approval of such Tax Return unless, as the basis
for withholding such approval, the position deals with an issue arising solely
in the post-Acquisition portion of the Straddle Period (in which event, assuming
the existence of a reasonable basis (within the meaning of Section 6662 of the
Code) therefor, CIBC may control the decision as to the appropriate position
with respect thereto) or CIBC demonstrates, by providing to the Authorized
Representative an opinion of counsel reasonably acceptable to the Authorized
Representative or of a "Big Six" accounting firm to such effect, that
substantial authority (within the meaning of Section 6662 of the Code) does not
exist for a position taken on such Tax Return. The failure of CIBC to propose
any changes to any such Tax Return within such 10-day period shall be deemed to
constitute CIBC's approval thereof. CIBC and the Authorized Representative shall
attempt in good faith mutually to resolve any disagreements regarding such Tax
Returns prior to the due date for filing thereof; provided, however, that the
failure to resolve all disagreements prior to such date shall not relieve CIBC
of its obligation to file (or cause to be filed) any such Tax Return in the form
and manner in which it was prepared by the Authorized Representative. Any
disagreements regarding such Tax Returns which are not resolved prior to the
filing thereof shall be promptly resolved pursuant to Section 7 hereof.

                        (ii) CIBC shall pay or cause to be paid the Tax
Liability due with respect to any Straddle Period Tax Return of a member of the
Holdings Subgroup; provided, however, that, no later than 5 business days prior
to the due date for filing any such Tax Return (taking into account extensions),
the Authorized


                                       14

<PAGE>   15

Representative, subject to Section 3(e) hereof, shall cause a check to be drawn
on the Tax Payment Account to the extent of the Holdings Subgroup Tax Amount.

                 (2) The Authorized Representative shall prepare, and OGI shall
file or cause to be filed (except to the extent provided in Section 3(d)(2)(i)
below, in the form and manner so prepared by the Authorized Representative), all
Tax Returns (other than a Combined Return) of or which include any member of the
Opgroup Subgroup or any Foreign Subsidiary thereof for a Straddle Period. The
Authorized Representative shall provide OGI with each such Tax Return at least
20 days prior to the due date for filing thereof, together with a statement
setting forth in reasonable detail a calculation of the portion of the Taxes
shown to be due on such Tax Return which is allocable to Opgroup Subgroup
through the Merger Date pursuant to Section 2(b) hereof (the "Opgroup Subgroup
Tax Amount").

                        (i) OGI shall have the right to review and approve
(which approval shall not be unreasonably withheld) each such Tax Return for 10
days following receipt thereof; provided, however, that OGI shall be deemed to
have unreasonably withheld its approval of such Tax Return unless, as the basis
for withholding such approval, the position deals with an issue arising solely
in the post-Merger portion of the Straddle Period (in which event, assuming the
existence of a reasonable basis (within the meaning of Section 6662 of the Code)
therefor, OGI may control the decision as to the appropriate position with
respect thereto) or OGI demonstrates, by providing to the Authorized
Representative an opinion of counsel reasonably acceptable to the Authorized
Representative or of a "Big Six" accounting firm to such effect, that
substantial authority (within the meaning of Section 6662 of the Code) does not
exist for a position taken on such Tax Return. The failure of OGI to propose any
changes to any such Tax Return within such 10-day period shall be deemed to
constitute OGI's approval thereof. OGI and the Authorized Representative shall
attempt in good faith mutually to resolve any disagreements regarding such Tax
Returns prior to the due date for filing thereof; provided, however, that the
failure to resolve all disagreements prior to such date shall not relieve OGI of
its obligation to file (or cause to be filed) any such Tax Return in the form
and manner in which it was prepared by the Authorized Representative. Any
disagreements regarding such Tax Returns which are not resolved prior to the
filing thereof shall be promptly resolved pursuant to Section 7 hereof.

                        (ii) OGI shall pay or cause to be paid the Tax Liability
due with respect to any Straddle Period Tax Return of a member of the Opgroup
Subgroup; provided, however, that, no later than 5 business days prior to the
due date for filing any such Tax Return (taking into account extensions), the
Authorized


                                       15

<PAGE>   16

Payment Subaccount shall be equal to Holdings Good Faith Estimate multiplied by
105%.

                        (ii) The "Opgroup Tax Payment Subaccount" shall be
established in favor of OGI and the Seller Trust. The amount of the Opgroup Tax
Payment Subaccount shall be equal to the Opgroup Good Faith Estimate multiplied
by 105%.

                  (4) Subject to Section 3(e)(6) hereof, amounts in the
respective Tax Payment Subaccounts shall be free from the claims of CIBC (in the
case of the Opgroup Tax Payment Subaccount) and OGI (in the case of the Holdings
Tax Payment Subaccount) and shall be held for the purposes set forth in this
Section 3(e) and Section 2.3 of the Acquisition Agreement.

                  (5) Except with respect to an Excluded Liability, CIBC shall
have the authority to make payments from the Holdings Subaccount to Governmental
Authorities on behalf of the Holdings Subgroup and OGI shall have authority to
make payments from the Opgroup Subaccount to Governmental Authorities on behalf
of the Opgroup Subgroup, after one day's notice to the Authorized
Representative, if CIBC or OGI, as the case may be, reasonably believes that
such payment is required to avoid incurring interest, penalties or other
additional Tax Liabilities with respect to any taxable period of the Opgroup
Consolidated Group that includes the Acquisition Date or any taxable period
ending before the Acquisition Date for which Tax Returns are not filed until
after the Acquisition Date.

                  (6) Notwithstanding anything in Section 3(e)(4) hereof or
Section 2.3(b) of the Acquisition Agreement to the contrary, after (i) filing of
all Tax Returns that the Authorized Representative believes are required to be
filed with respect to such Tax Payment Subaccount (with the good faith
concurrence of OGI or CIBC, as the case may be), (ii) payment of Taxes with
respect to which amounts in the Tax Payment Subaccount were deposited and (iii)
the payment pursuant to the proviso in Section 2.3(b) of the Acquisition
Agreement, amounts remaining in a Tax Payment Subaccount shall be transferred
(x) by CIBC, with respect to any amounts remaining in the Holdings Tax Payment
Subaccount, to the Opgroup Tax Payment Subaccount, or (y) by OGI, with respect
to any amounts remaining in the Opgroup Tax Payment Subaccount, to the Holdings
Tax Payment Subaccount; provided, however, that, if any amounts have been
released pursuant to this Section 3(e)(6) to a Tax Payment Subaccount, any
amounts remaining in the recipient Tax Payment Subaccount shall be distributed
directly to the Seller Trust after the filing of all Tax Returns that the
Authorized Representative believes are required to be filed with respect to such
Tax


                                       16

<PAGE>   17

Payment Subaccount (with the good faith concurrence of OGI or CIBC, as the case
may be), the payment of Taxes with respect to which amounts were allocated to
such Tax Payment Subaccount and the making of the payment described in clause
(iii) above in this Section 3(e)(6); and provided further, however, that, after
the filing of all federal, state and local income and franchise Tax Returns and
other material Tax Returns, CIBC and OGI may jointly authorize interim partial
distributions to the Seller Trust from the two Tax Payment Subaccounts.

      4.    RESPONSIBILITY AND INDEMNIFICATION FOR TAXES.

            (a) Responsibility of and Indemnification by CIBC. Except as
otherwise provided in Sections 3 and 4(b) hereof, CIBC shall be responsible for,
and, except as otherwise provided in Section 4(b) hereof, CIBC shall indemnify
and hold harmless OGI and its shareholders, directors, officers, employees,
affiliates, agents and successors from and against all Losses of any member of
the OGI Post-Merger Group arising from, any and all Taxes attributable to any
member of the Holdings Subgroup for any Pre-Acquisition Taxable Period,
Post-Acquisition Taxable Period, or Straddle Period.

            (b) Responsibility of and Indemnification by PIMCO LP. Except as
otherwise provided in Section 3 hereof, PIMCO LP shall be responsible for, and
PIMCO LP shall indemnify and hold harmless CIBC and its shareholders, directors,
officers, employees, affiliates, agents and successors from and against all
Losses of any member of the CIBC Post-Acquisition Group arising from, any and
all Taxes (1) attributable to any member of the Opgroup Subgroup for any
Pre-Merger Taxable Period, Post-Merger Taxable Period, or Straddle Period
(including any disallowance of deductions claimed with respect to the interest
of Opfin in Tower A Associates in Pre-Merger Taxable Periods or Straddle
Periods); or (2) attributable to any member of the Holdings Subgroup by reason
of an increase in the grossed-up purchase price, as described in Treas. Reg.
Section 1.338(h)(10)-l(f)(2)(ii)(A), for the Section 338(h)(10) Elections over
that reported on the Tax Returns filed in accordance with Section 3(b)(3)
hereof, and CIBC shall have no obligations to OGI or PIMCO LP pursuant to
Section 4(a) with respect to such Losses. Any indemnification payments by PIMCO
LP under this Section 4(b) shall be considered to have been made on behalf of,
and in lieu of an actual contribution of funds to, OGI.

            (c) Procedure for Payment.

                  (1) Subject to the provisions of Sections 3 and 8 hereof, to
the extent CIBC or OGI is responsible for a payment of Taxes under Sections 4(a)
or 4(b)


                                       17

<PAGE>   18

hereof, respectively, such responsible party shall promptly pay (or cause to be
paid) such Taxes to the appropriate Governmental Authority when due.

                  (2) If the Indemnifying Party is required to indemnify the
Indemnified Party pursuant to this Section 4, the Indemnified Party shall submit
its calculations, in sufficient detail so as to permit the Indemnifying Party to
understand the computation thereof, of the amount required to be paid pursuant
to this Section 4, which shall be net of the Present Value Benefit realized or
realizable by the Indemnified Party (such net amount being the "Indemnification
Amount"). Subject to the following sentence, the Indemnifying Party shall pay to
the Indemnified Party, no later than 10 days after the Indemnifying Party
receives the Indemnified Party's calculations, the Indemnification Amount. If
the Indemnifying Party disagrees with such calculations, it must notify the
Indemnified Party of its disagreement in writing within 10 days of receiving
such calculations. Any dispute regarding such calculations shall be resolved in
accordance with Section 7 of this Agreement.

            (d) Time Limits. Any claim under this Section 4 with respect to a
Tax Liability must be made in accordance with the notification procedures of
Section 8 hereof and no later than thirty (30) days after the expiration of the
applicable statute of limitations for assessment of such Tax Liability.

      5.    CARRYBACKS AND CARRYOVERS.

            (a) In the event that any member of the OGI Post-Merger Group
realizes any loss, deduction, credit or other Tax attribute in any taxable
period (or portion thereof) beginning after the Merger Date, such member may, to
the extent permitted by law, utilize such loss, deduction, credit or other Tax
attribute and obtain any available Refund, including by carrying back such loss,
deduction, credit or Tax attribute to a prior Opgroup Consolidated Group taxable
year; provided, however, that (except as provided in the second proviso in this
sentence), to the extent such carryback is elective, such member of the OGI
Post-Merger Group may only carry back such item with the consent of the
Authorized Representative (which may be withheld in its sole discretion if the
taxable period to which such item may be carried back has not yet been subject
either to audit or to a prior or concurrent mandatory carryback); and provided
further, however, that, if such item is the result of a disallowance of a
Section 381 attribute that was claimed by a member of the OGI Post-Merger Group
for a Straddle Period, such item shall be carried back to prior taxable years of
the Opgroup Consolidated Group or the OGI Post-Merger Group, as the case may be,
to the extent permitted by law, unless CIBC notifies OGI in writing that such
item is not to be so


                                       18

<PAGE>   19


carried back. CIBC shall cooperate with OGI in seeking from the appropriate
taxing authority any Refund that reasonably would result therefrom. Except to
the extent that such Refund is the result of a disallowance of a loss,
deduction, credit or other Tax attribute claimed by, or a reduction in an item
of income or gain reported by, a member of the Opgroup Consolidated Group for a
Pre-Acquisition Taxable Period or the pre-Acquisition portion of a Straddle
Period or is attributable to the disallowance of a Section 381 attribute (in any
such event such Refund shall be paid first to CIBC to offset any related
increase in Tax Liabilities borne by CIBC for Pre-Acquisition Taxable Period(s)
or Straddle Period(s) (to the extent not previously indemnified under the
Acquisition Agreement or this Agreement) and second to the Seller Trust), OGI
shall be entitled to any Refund (or other Tax benefit including any interest
thereon received from such taxing authority) realized by a member of the OGI
Post-Merger Group attributable to such loss, deduction, credit or other Tax
attribute.

            (b) In the event that any member of the CIBC Post-Acquisition Group
realizes any loss, deduction, credit or other Tax attribute in any taxable
period (or portion thereof) beginning after the Acquisition Date, such member
may, to the extent permitted by law, utilize such loss, deduction, credit or Tax
attribute and obtain any available Refund, including by carrying back such loss,
deduction, credit or other Tax attribute to a prior Opgroup Consolidated Group
taxable year; provided, however, that, to the extent such carryback is elective,
such member of the CIBC Post-Acquisition Group may only carry back such item
with the consent of the Authorized Representative (which may be withheld in its
sole discretion if the taxable period to which such item may be carried back has
not yet been subject either to audit or to a prior or concurrent mandatory
carryback). OGI shall cooperate with CIBC in seeking from the appropriate taxing
authority any Refund that reasonably would result therefrom. Except to the
extent that such Refund is the result of a disallowance of a loss, deduction,
credit or other Tax attribute claimed by, or a reduction in an item of income or
gain reported by, a member of the Opgroup Consolidated Group for a Pre-Merger
Taxable Period or the pre-Merger portion of a Straddle Period (in either which
event such Refund shall be paid first to OGI to offset any related increase in
Tax Liabilities borne by the Opgroup Subgroup for Pre-Merger Taxable Period(s)
or Straddle Period(s) (to the extent not previously indemnified under the Merger
Agreement or this Agreement) and second to the Seller Trust), CIBC shall be
entitled to any Refund (or other Tax benefit including any interest thereon
received from such taxing authority) realized by a member of the CIBC
Post-Acquisition Group attributable to such loss, deduction, credit or other Tax
attribute.

            (c) In the event that any Excluded Affiliate realizes any loss,
credit or other Tax attribute in any taxable period (or portion thereof)
beginning after the Merger


                                       19

<PAGE>   20

Date, such member may carry back such loss, credit or Tax attribute to a prior
Opgroup Consolidated Group taxable year. CIBC and OGI shall cooperate with the
Authorized Representative in seeking from the appropriate taxing authority any
Refund that reasonably would result from such carryback. The Seller Trust shall
be entitled to any Refund (or other Tax benefit) realized by any Excluded
Affiliate (including any interest thereon received from such taxing authority)
attributable to such carryback.

            (d) The OGI Post-Merger Group also shall be entitled to the benefit,
in Post-Merger Taxable Periods, of any net operating loss, capital loss or other
carryforward, unused investment, foreign tax or other credit arising in a
Pre-Merger Taxable Period of the Opgroup Consolidated Group (including from any
member of the Holdings Subgroup); provided, however, that members of the CIBC
Post-Acquisition Group shall have priority with respect to the benefit, in
Post-Acquisition Taxable Periods, of any carryforward which is legally available
from the Holdings Subgroup. OGI or CIBC, as the case may be (the "Recipient"),
shall apply the Present Value Benefit of such carryforward in the following
order of priority: (1) to offset any resulting increase in Tax Liabilities for
Pre-Acquisition or Pre-Merger Taxable Period(s) (to the extent not previously
indemnified under the Acquisition Agreement, the Merger Agreement or this
Agreement), (2) to the Recipient to the extent of any uncompensated Losses for
Pre-Merger or Pre-Acquisition Taxable Periods, (3) to the non-Recipient to the
extent of any uncompensated Losses for Pre-Acquisition or Pre-Merger Taxable
Periods, and (4) to the Seller Trust.

      6. COOPERATION; MAINTENANCE AND RETENTION OF RECORDS. CIBC shall, and
shall cause the Members of the CIBC Post-Acquisition Group, OGI shall, and shall
cause the members of the OGI Post-Merger Group, and the Managing Trustees shall,
and shall cause the Authorized Representative, to provide a requesting party
with such assistance and documents as may be reasonably requested by such
requesting party in connection with (i) the preparation of any Tax Return, (ii)
the conduct of any Proceeding, (iii) any matter relating to Taxes of any member
of the Opgroup Consolidated Group, the Opgroup Subgroup, the Holdings Subgroup,
the CIBC Post-Acquisition Group, or the OGI Post-Merger Group and (iv) any
other matter that is a subject of this Agreement, and the requesting party shall
pay any reasonable out-of-pocket expenses incurred by the assisting party in
connection therewith. CIBC, OGI and the Managing Trustees shall retain or cause
to be retained all Tax Returns, schedules and workpapers, and all material
records or other documents relating thereto, until the expiration of the statute
of limitations (including any waivers or extensions thereof) of the taxable
years to which such Tax Returns and other documents relate or until the
expiration of any additional period that any party reasonably requests, in


                                       20

<PAGE>   21

writing, with respect to specific material records or documents. A party
intending to destroy any material records or documents shall provide each other
party with reasonable advance notice and the opportunity to copy or take
possession of such records and documents. The parties hereto will notify each
other party in writing of any waivers or extensions of the applicable statute of
limitations that may affect the period for which the foregoing records or other
documents must be retained.

      7. DISPUTES. If the parties disagree as to the amount of any payment to be
made under, or any other matter arising out of, this Agreement, the parties
shall attempt in good faith to resolve such dispute, and any agreed upon amount
shall be paid to the appropriate party. If such dispute is not resolved within
15 days, the parties shall jointly retain the Independent Accounting Firm to
resolve the dispute. The fees of the Independent Accounting Firm shall be borne
equally by the parties having the dispute, and the decision of such Independent
Accounting Firm shall be final and binding on all parties involved. Following
the decision of the Independent Accounting Firm, the parties shall each take or
cause to be taken any action that is necessary or appropriate to implement such
decision of the Independent Accounting Firm, including, without limitation, the
prompt payment of underpayments or refund of overpayments, with interest
calculated on such overpayments and underpayments at the Overpayment Rate from
the date such payment was due through the date such underpayment or overpayment
is paid or refunded.

      8.    PROCEEDINGS.

                  (1) CIBC shall, promptly upon receipt of notice thereof by any

<PAGE>   22
a Tax Liability (or an issue related thereto) of any Member of the Opgroup

                  (3) The Managing Trustees shall, promptly upon receipt of

any pending or threatened Proceeding in connection with a Tax Liability (or an
issue related thereto) for a member of the Opgroup Subgroup and (2) from OGI,
notify CIBC in writing of any communication with respect to any pending or

            (b) Pre-Acquisition and Pre-Merger Taxable Periods and Straddle
Periods. The Authorized Representative shall have the primary responsibility to
represent the interests of the members of the Opgroup Consolidated Group, the
Holdings Subgroup, the Opgroup Subgroup and any Foreign Subsidiary thereof in
any Proceeding relating to Pre-Acquisition and/or Pre-Merger Taxable Periods
and/or Straddle Periods and to employ counsel of its choice at its expense;
provided, however, that (i) CIBC and OGI each shall be permitted to participate
(at its own expense) in any such Proceedings and all hearings relating thereto
and the Authorized Representative's counsel shall give due consideration to all
comments and suggestions received from CIBC and OGI; (ii) the Authorized
Representative shall not settle any dispute or tax issue with a taxing authority
without the consent of CIBC or OGI, as the case may be, which consent, in each
case, shall not unreasonably be withheld; and (iii) primary responsibility shall
shift to OGI at such time, if ever, that the asserted Tax Liabilities exceed the
then balance in the Indemnity Trust or to CEBC at such time, if ever, that the
asserted Tax Liabilities exceed the then balance of the Holdback Amount; and
provided further, however, that primary responsibility with respect to any item
shall shift to CEBC or OGI, as the case may be, if they are responsible to the
other under Sections 4(a) or 4(b) but are not entitled to indemnification for
Losses attributable to such item under the Acquisition Agreement or the Merger
Agreement, respectively.

            (c)  Post-Acquisition and Post-Merger Taxable Periods.

                 (1) CIBC shall have the sole right to represent the interests
of the CIBC Post-Acquisition Group (or any member thereof) in any Proceeding
relating to a


                                       22

<PAGE>   23

Post-Acquisition Taxable Period; provided, however, that the Seller Trust shall
be permitted to participate at its own expense in any such Proceeding; and
provided further, however, that, if CIBC has asserted (or is reasonably likely
to assert) that the Seller Trust may be liable for indemnification under the
Acquisition Agreement, CIBC shall not settle or otherwise resolve any dispute or
tax issue with a taxing authority without the consent of the Seller Trust, which
consent shall not unreasonably be withheld.

                 (2) OGI and PIMCO LP shall have the sole right to represent the
interests of the OGI Post-Merger Group (or any member thereof) in any Proceeding
relating to a Post-Merger Taxable Period; provided, however, that the Indemnity
Trust shall be permitted to participate at its own expense in any such
Proceeding and provided further, however, that, if OGI has asserted (or is
reasonably likely to assert) that the Indemnity Trust may be liable for
indemnification under the Merger Agreement, OGI and PIMCO LP shall not settle or
otherwise resolve any dispute or tax issue with a taxing authority without the
consent of the Indemnity Trust, which consent shall not unreasonably be
withheld.

            (d) Power of Attorney. Each member of the CIBC Post-Acquisition
Group and the OGI Post-Merger Group (each a "Represented Party") shall execute
and deliver to the Authorized Representative any power of attorney requested by
the Authorized Representative in connection with any Proceeding described in
Section 8(b) hereof; provided, however., that such power of attorney is required
to permit the Authorized Representative to conduct such Proceeding; and provided
further, however, that such power of attorney shall not negate any right of a
Represented Party to consent to settlements provided in Section 8(b) hereof or
to otherwise act on its own behalf pursuant to this Agreement.

      9. INTEREST; METHOD OF PAYMENT. Any payment required by this Agreement
that is not made on or before the date such payment is required to be made
hereunder shall bear interest after such date at the Overpayment Rate. All
payments made pursuant to this Agreement shall be made in immediately available
funds.

      10. COVENANT TO EFFECT SECTION 338(h)(10) ELECTIONS. CIBC, Opgroup, the
Authorized Representative, OGI and PIMCO LP shall take or cause to be taken all
actions required by applicable law to make valid Section 338(h)(10) Elections

designated by CIBC, any other subsidiary of Holdings, and, to the extent
designated by the Authorized Representative, any Excluded Affiliate.

      11. TERMINATION OF PRIOR TAX SHARING AGREEMENTS. This Agreement shall take
effect on the Acquisition Date and shall replace all other agreements, whether
or not written, in respect of any Taxes between or among any members of the
Opgroup Subgroup on the one hand and the Holdings Subgroup on the other,
including the Tax Allocation Agreement; provided, however, that this Agreement
shall not supersede any agreements with respect to Taxes set forth in the
Acquisition Agreement and/or the Merger Agreement. All such replaced agreements
shall be cancelled as of the Acquisition Date to the extent they relate to any
members of the Holdings Subgroup and as of the Merger Date to the extent they
relate to any members of the Opgroup Subgroup, and any rights or obligations of
any members of the Opgroup Subgroup or Holdings Subgroup existing under such
agreements thereby shall be fully and finally settled without any payment by any
party thereto.

      12. AMENDMENT. This Agreement may be amended, modified or supplemented
only by a written agreement signed by all of the parties hereto.

      13. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, without reference to choice
of law principles, including matters of construction, validity and performance.

      14. NOTICES. Notices, requests, permissions, waivers, and other
