                  of each Partnership Year, Available Cash shall be distributed
                  to the Partners in proportion to their respective Percentage
                  Interests in an aggregate cumulative amount at least equal to
                  the sum of (1) the income tax liability for the Partner with
                  the largest percentage income tax liability (of itself or its
                  shareholders) from cumulative Partnership taxable income
                  allocated to such Partner under Subsection 5.2(b) hereof, and
                  (2) for the other Partners, a proportional cash amount
                  adjusted only for respective Percentage Interests; and

                               (ii) Any remaining Available Cash shall be
                  distributed to the Partners in proportion to their respective
                  Percentage Interests at such times and in such amounts as the
                  General Partner shall determine.

                  5.2 Partnership Allocations.

                  (a) If any payments to a Partner by the Partnership under an
agreement other than this Agreement are determined for Federal income tax
purposes not to constitute (1) payments to a partner other than in its capacity
as a partner under Section 707(a) of the Code or (2) guaranteed payments under
Section 707(c) of the Code, gross income of the Partnership shall first be
allocated to each such Partner in proportion to and up to the excess of (x) the
aggregate cumulative amount of such payments by the Partnership to such Partner
over (y) the aggregate cumulative amount of gross income previously allocated to
such Partner pursuant to this Subsection 5.2(a). Such allocated gross income

                                  11




shall consist of pro rata portions of each item of income and gain recognized by
the Partnership in the taxable year.

                  (b) Except as otherwise provided in Subsection 5.2(a) or (c)
or elsewhere in this Agreement, for purposes of this Agreement, and for federal,
state and local income tax purposes, all items of Profits, Losses, income, gain,
loss, deduction or credit shall be determined with respect to each taxable year
of the Partnership as of the end thereof, and allocated to the Partners in
accordance with their Percentage Interests. Each Partner's Percentage Interest
shall constitute its interest in partnership profits for purposes of determining
such Partner's share of nonrecourse liabilities of the Partnership under Temp.
Treas. Reg. ss.1.752-1T(e)(3)(ii)(C).

                  (c) Notwithstanding Subsections 5.2(a) and (b):

                      (i) Minimum Gain and Hypothetical Capital Accounts. For
purposes of complying with Treasury Regulations relating to tax allocation, the
Partnership's "minimum gain," "minimum gain attributable to partner nonrecourse
debt" and the Partners' hypothetically adjusted Capital Accounts ("Hypothetical
Capital Accounts") must be determined from time to time. The amount of minimum
gain or minimum gain attributable to partner nonrecourse debt is determined in
accordance with Temp. Treas. Reg. ss.1.704-1T(b)(4)(iv)(c) or
1.704-1T(b)(4)(iv)(h)(6), as the case may be, by computing, with respect to each
nonrecourse liability of the Partnership, the amount of gain (of whatever
character), if any, that would be realized by the Partnership if it disposed of
(in a taxable transaction) the Partnership property subject to such liability in
full satisfaction thereof, and by then aggregating the amounts so computed. A
Partner's Hypothetical Capital Account shall equal its true Capital Account,
increased by any amount that such Partner is treated as being obligated to
restore under Treas. Reg. ss.1.704- 1T(b)(2)(ii)(c) (including the Partner's
share of minimum gain, computed as provided in Temp. Treas. Reg.
ss.1.704-1T(b)(4)(iv)(f), and of minimum gain attributable to partner
nonrecourse debt, computed as provided in Temp. Treas. Reg. ss.1.704-
1T(b)(4)(iv)(h)(5)), and decreased by the items described in Treas. Reg.
ss.1.704-1(b)(2)(ii)(d), clauses (4), (5) and (6). For purposes of determining
each Partner's share of minimum gain or minimum gain attributable to partner
nonrecourse debt, any distributions pursuant to Section 5.1(a) shall be treated
as allocable to the nonrecourse liabilities, if any, that are incurred by the
Partnership in connection with such distributions.

                           (ii) Qualified Income Offset. A Partner who
unexpectedly receives an adjustment, allocation, or distribution described in
Treas. Reg. ss.1.704-1(b)(2)(ii)(d), clauses (4), (5) and (6), that creates a
deficit in his Hypothetical Capital account shall be allocated items of income
and gain (consisting of a pro rata portion of each item of Partnership income,
including gross income, and gain for such year) in an amount and

                                       12




manner sufficient to eliminate such deficit as quickly as possible.

                           (iii) Minimum Gain Chargeback. If there is a net
decrease in the Partnership's minimum gain or minimum gain attributable to
partner nonrecourse debt during a Partnership taxable year, any Partner with a
share of such minimum gain at the beginning of such year shall be allocated,
before any other allocation is made of Partnership items for such taxable year,
items of income and gain for such year (and, if necessary, subsequent years) in
proportion to, and to the extent of, an amount equal to the greater of (A) the
portion of such Partner's share of the net decrease in such minimum gain that is
allocable to the disposition of Partnership property or (B) the deficit balance
in such Partners's Hypothetical Capital Account as of the end of such year (but
before any allocations of income or loss for such year) in accordance with Temp.
Treas. Reg. ss.ss.1.704- 1T(b)(4)(iv)(e) and 1.704-1T(b)(4)(iv)(h)(4) (the
"Minimum Gain Chargeback"). The Minimum Gain Chargeback allocated in any taxable
year shall consist first of gains recognized from the disposition of items of
Partnership property subject to one or more nonrecourse liabilities of the
Partnership to the extent of the decrease in Minimum Gain attributable to the
disposition of such items of property, with the remainder of the Minimum Gain
Chargeback, if any, made up of a pro rata portion of the Partnership's other
items of income and gain for that year.

                           (iv) Special Limitation on Losses Allocated to a
Limited Partner. No loss or deduction shall be allocated to a Limited Partner to
the extent that such allocation would reduce such Partner's Hypothetical Capital
Account below zero, and such loss or deduction shall instead be allocated to the
other Partners in proportion to the positive balances of their respective
Hypothetical Capital Accounts.

                           (v) Restoration. If any items of income, gain,
loss or deduction shall be specially allocated pursuant to paragraph (ii), (iii)
or (iv) of this Subsection 5.2(c), then as quickly as possible thereafter (but
not in such a manner as to create or increase a deficit in any Partner's
Hypothetical Capital Account) items of income, gain, loss or deduction shall be
specially allocated to other Partners so as to return all Capital Accounts to
such balances as they would have had if no such special allocations had been
made pursuant to Paragraph (ii), (iii) or (iv) of this Subsection 5.2(c).

                           (vi) Rule of Construction. This Section 5.2 is
intended to satisfy the alternate test for economic effect set forth in Treas.
Reg. ss.1.704-1T(b)(2)(ii)(d) and the rules for allocations of nonrecourse
deductions set forth in Temp. Treas. Reg. ss.1.704-1T(b)(4)(iv)(d) and
allocations of partner nonrecourse deductions set forth in Temp. Treas.
Reg. ss.1.704-1T(b)(4)(iv)(h) and should be so construed.

                                       13



                  5.3 Tax Allocations; Code Section 704(c).

                  (a) In accordance with Section 704(c) of the Code and the
Treasury Regulations thereunder, income, gain, loss, and deduction with respect
to any property contributed to the capital of the Partnership shall, solely for
tax purposes, be allocated among the Partners so as to take account of any
variation between the adjusted basis of such property to the Partnership for
federal income tax purposes and its initial Gross Asset Value.

                  (b) In the event the Gross Asset Value of any asset of the
Partnership shall be adjusted pursuant to the provisions of this Agreement,
subsequent allocations of income, gain, loss and deduction with respect to such
asset shall take account of any variation between the adjusted basis of such
asset for federal income tax purposes and its Gross Asset Value in the same
manner as under Section 704(c) of the Code and the Treasury Regulations
thereunder.

                  (c) Any elections or other decisions relating to such Section
704(c) allocations shall be made by the Partners in any manner that reasonably
reflects the purpose and intention of this Agreement. Section 704(c) allocations
pursuant to this Section 5.3 are solely for purposes of federal, state, and
local taxes and shall not affect, or in any way be taken into account in
computing, any partner's Capital Account or share of profits, Losses, other
items, or distributions pursuant to any provision of this Agreement.

                  5.4 Accounting Method. The books of the Partnership
(for both tax and financial reporting purposes) shall be kept on
an accrual basis.

                                    ARTICLE 6

                                   MANAGEMENT

                  6.1 Rights and Duties of the Partners.

                  (a) The Limited Partners as limited partners in the
Partnership shall not participate in the control of the business of the
Partnership and shall have no power to act for or bind the Partnership.

                  (b) Pursuant to Pennsylvania law, each Limited Partner shall
not be liable for losses or debts of the Partnership beyond the aggregate amount
such Partner is required to contribute to the Partnership pursuant to this
Agreement plus his share of the undistributed net profits of the Partnership,
except that a Partner may be liable under Pennsylvania law to repay certain
distributions received by it.

                  6.2 Fiduciary Duty of General Partner. The General
Partner shall have fiduciary responsibility for the safekeeping

                                       14




and use of all funds and assets (including records) of the partnership, whether
or not in his immediate possession or control, and the General Partner shall not
employ, or permit another to employ, such funds or assets in any manner except
for the exclusive benefit of the Partnership.

                  6.3 Powers of General Partner.

                  (a) Subject to the terms and conditions of this Agreement, the
General partner shall have full and complete charge of all affairs of the
Partnership, and the management and control of the Partnership's business shall
rest exclusively with the General Partner. Except as otherwise provided in the
Act or by this Agreement, the General Partner shall possess all of the rights
and powers of a partner in a partnership without limited partners under
Pennsylvania law. The General Partner shall be required to devote to the conduct
of the business of the Partnership such time and attention as is necessary to
accomplish the purposes, and to conduct properly the business, of the
Partnership.

                  (b) Subject to the limitations set forth in this Agreement,

                      (ii) make investments in United States government

                  adequate records and accounts of all operations and

                  to in Section 8.2;

                  protect the Partnership's properties, business, partners and
                  employees and to protect the General Partner and its
                  employees;

                      (vi) employ, at the expense of the Partnership,
                  consultants, accountants, attorneys and others and terminate
                  such employment; provided, however, that if any Affiliate of

                      (viii) incur indebtedness, borrow funds and/or issue
                  guarantees, in each case for the conduct of the Partnership's
                  business as described in Section 1.4.

By executing this Agreement, each Limited Partner shall be deemed to have
consented to any exercise by the General Partner of any of the foregoing powers.

                  6.4 Other Activities. Any Partner (other than the General
Partner in such capacity) (the "Interested Party") may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, whether presently existing or hereafter created, and neither the
Partnership nor any Partner (including the General Partner) other than the
Interested Party shall have any rights in or to such independent ventures or the
income or profits derived therefrom.

                  6.5 Transactions with Affiliates.

                  (a) Nothing in this Agreement shall preclude transactions
between the Partnership and any Partner (including the General Partner) or an
Affiliate or Affiliates of any Partner acting in and for its own account,
provided that any services performed or products provided by the Partner or any
such Affiliates are services an/or products that the General Partner reasonably
believes, at the time of requesting such services and/or products, to be in the
best interests of the Partnership, and further provided that the rate of
compensation to be paid for any such services and/or products shall be
comparable to the amount paid for similar services and/or products under similar
circumstances to or by independent third parties in arm's length transactions.

                                       16




                  (b) All bills with respect to services provided to the
Partnership by a Partner or any affiliate of a Partner shall be separately
submitted and shall be supported by logs or other written data.

                  (c) Nothing contained herein shall preclude the Partnership

as a fiduciary of the Partnership or to a breach by the General Partner of any
of the terms and provisions of this Agreement.

                                    ARTICLE 7

                                  COMPENSATION

                  The General Partner shall be entitled to reimbursement of all
of its expenses attributable to the performance of its obligations hereunder, as
provided in Article 4 hereof, to the extent permitted by Section 6.5. Subject to
the Act, no amount so paid to the General Partner shall be deemed to be a

reimbursement of its expenses and its right to distributions as provided in this
Agreement, the General Partner shall not receive any compensation for its
services as such.

                                    ARTICLE 8

                                    ACCOUNTS

                  8.1 Books and Records. The General Partner shall maintain
complete and accurate books of account of the Partnership's affairs at the
Partnership's principal office, including a list of the names and addresses of
all Partners. Each Partner shall have the right to inspect the Partnership's
books and records (including the list of the names and addresses of Partners).
Each of the Partners shall have the right to audit independently the books and
records of the Partnership, any such audit being at the sole cost and expense of
the Partner conducting such audit.

                  8.2 Reports, Returns and Audits.

                  (a) The books of account shall be closed promptly after the
end of each Partnership Year. The books and records of the Partnership shall be
audited as of the end of each Partnership Year by the Auditor. Within ninety
days after the end of such Partnership Year, the General Partner shall make a
written report to each person who was a Partner at any time during such
Partnership Year which shall include financial statements comprised of at least
the following: a balance sheet as of the close of the preceding Partnership Year
and a statement of earnings or losses, changes in financial position and changes
in Partners' Capital Accounts for the Partnership Year then

                                       18




ended, which financial statements shall be certified by the Auditor as in
accordance with Generally Accepted Accounting Principles.

                  (b) Prior to May 15 of each year, each Partner shall be
provided with an information letter (containing such Partner's Form K-1 or
comparable information) with respect to its distributive share of income, gains,
deductions, losses and credits for income tax reporting purposes for the
previous Partnership Year, together with any other information concerning the
Partnership necessary for the preparation of a Partner's income tax return(s),
and the Partnership shall provide each Partner with an estimate of the
information to be set forth in such information letter by no later than April 15
of each year. With the sole exception of mathematical errors in computation, the
financial statements and the information contained in such information letter
shall be deemed conclusive and binding upon such Partner unless written
objection shall be lodged with the General Partner within ninety days after the
giving of such information letter to such Partner.

                  (c) The General Partner shall also furnish the Partners with
quarterly financial statements of the Partnership and such other periodic
reports concerning the Partnership's business and activities as the General
partner considers necessary to advise all Partners properly about their
investment in the Partnership.

all federal, state and local returns of the Partnership (the "Returns") for each
year or other period for which such Returns are required to be filed. To the
extent permitted by law, for purposes of preparing the Returns, the Partnership
shall use the Partnership Year. The General Partner may make any elections under
the Code and/or applicable state or local tax laws, and the General Partner
shall be absolved from all liability for any and all consequences to any
previously admitted or subsequently admitted Partners resulting from its making
or failing to make any such election. Notwithstanding the forgoing, the General
Partner shall make the election provided for in Section 754 of the Code, if
requested to do so by any Partner.

                  (e) The General Partner shall be the "tax matters partner," as
such term is defined in Section 6231(a)(7) of the Code.

                                    ARTICLE 9

                                    TRANSFERS

                  9.1 Transfer of General Partner's Interest.

                  (a) The General Partner shall not withdraw from the
Partnership or resign as General Partner nor shall it Transfer

                                       19




its general partner interest in the Partnership, in each case without the
written approval of the Limited Partners.

                  (b) The General Partner shall be liable to the Partnership for
any withdrawal or resignation in violation of Subsection 9.1(a) above.

                  9.2 Transfer of a Limited Partner's Interest.

                  (a) Except as otherwise provided in this Article 9, no Limited
Partner may Transfer its Partnership Interest or any portion thereof to any
Person without the written approval of the other Partners.

                  (b) The Limited Partners agree, upon request of the General
Partner, to execute such certificates or other documents and perform such acts
as the General Partner reasonably deems appropriate to preserve the status of
the Partnership as a limited partnership, after the completion of any Transfer
of an interest in the Partnership, under the laws of the Commonwealth of
Pennsylvania.

                  (c) A Limited Partner's Partnership Interest may be
transferred by such Limited Partner to any Affiliate or such Limited Partner
provided that (i) notice of the transfer is given to the Partnership and all
other Partners by the Limited Partner making the transfer, and (ii) the
Affiliate to whom such interest is to be transferred satisfies the condition set
forth in Subsection 9.4(b).

                  9.3 Partnership's Right of First Refusal. If either Sonoco, on
the one hand, or Engineering and Container on the other hand (for purposes of
this Section 9.3 and Section 9.4, Engineering and Container shall be treated as
a single Limited Partner) (the "Selling Partner") wishes to sell any Partnership
Interest (the "Offered Interest") pursuant to a bona fide written offer from a
third party to purchase the Offered Interest (a "Bona Fide Offer"), it shall
first give written notice (the "Notice of Sale") to the Partnership, and the
Partnership shall in turn forward a copy of such notice to the other Limited
Partner (the "Non-Selling Partner"), of its intention to do so. A Notice of Sale
shall name the proposed transferee and specify the amount of the Offered
Interest, the price and the terms of payment and shall have attached thereto a
copy of the Bona Fide Offer. The Partnership shall have the right to purchase
all but not less than all of the Offered Interest at the price and on the terms
of the Bona Fide Offer and shall exercise such rights by giving written notice
to the Selling Partner within 60 days after the Partnership shall have received
the Notice of Sale. If the Offered Interest constitutes less than all of the
Partnership Interests of the Selling Partner, nothing herein shall be construed
to give any party the right to purchase any Partnership Interest (or portion
thereof) that is not included in the Offered Interest.

                                       20




                  9.4 Limited Partner's Right of Second Refusal.

                  (a) If the Partnership does not elect to purchase the Offered
Interest within the time period specified in Section 9.3, the Partnership shall
so notify the Non-Selling Partner. The Non-Selling Partner shall have the right
to purchase all, but not less than all, of the Offered Interest at the price and
on the terms of the Bona Fide Offer and shall exercise such right as follows:

                           (i) Within 10 days after the Partnership notifies the
                  Non-Selling Partners of its election not to purchase the
                  Offered Interest, the Non-Selling Partners shall give the
                  Selling Partner written notice of such Non-Selling Partner's
                  election to purchase the Offered Interest.

                           (ii) If the Non-Selling Partner does not elect to
                  purchase the Offered Interest within the time period
                  specified, the Selling Partner may, within 30 days of the
                  expiration of the period specified in Clause (i) above, sell
                  the Offered Interest to the Person named and in accordance
                  with the terms set forth in the Bona Fide Offer; provided that
                  the condition set forth in paragraph (b) below shall have been
                  satisfied.

                  (b) As a condition precedent to the effectiveness of any
transfer of a Partnership Interest pursuant to this Agreement to any person or
entity not a party to this Agreement, such transferee shall agree in writing to
become a party to this Agreement with all of the rights and obligations relating
thereto. A copy of such agreement shall be executed by the transferee and
delivered to the Secretary of the General Partner.

                  9.5 Deviation from Bona Fide Offers. The parties hereby
acknowledge and agree that in cases where nonfungible property such as real
estate constitutes part of the price under the Bona Fide Offer and such offer
depends on the unique situation of the proposed transferee, or otherwise cannot
be precisely duplicated by anyone other than the proposes transferee, purchases
by any Non-Selling Partner or the Partnership pursuant to Section 9.3 or 9.4
shall be made for a consideration upon terms which constitute the reasonable
economic equivalent of the price and terms of the Bona Fide Offer as determined
by the Board of Directors of the General Partner. For these purposes, the
promissory note of any Non-Selling Partner of the Partnership shall be
considered the reasonable economic equivalent of the promissory note of the
proposed transferee, notwithstanding any differences in financial condition.

                  9.6 Partnership's Call Option.

                  (a) At any time within one year after there shall be a Change
in Control (as hereinafter defined) of a Limited Partner, the Partnership shall
have the right and option to purchase the

                                       21




Partnership Interest owned by the Limited Partner of which such Change in
Control occurred (the "Affected Partner") and such Affected Partner shall be
required to sell such Partnership Interests for the price and upon the terms set
forth in this Section 9.6. The option granted hereunder may be exercised by
written notice from the Partnership to the Affected Partner given at any time
prior to the expiration of said option. A "Change in Control" with respect to
either Engineering or Container (or an Affiliate thereof who may become a
Limited Partner hereunder after the date hereof) means the sale or transfer by
Donald C. Graham, directly or indirectly, of the beneficial ownership of capital
stock representing fifty percent (50%) or more of the outstanding voting rights
of such Limited Partner to a transferee or transferees other than an Affiliate
of Engineering or Container, the spouse or a lineal descendant (whether natural
or adopted) of Donald C. Graham, his estate or a trust created for the benefit
of Donald C. Graham or his spouse or lineal descendants. A "Change in Control"
of any other Limited Partner means the sale or transfer, directly or indirectly,
to a person (as "person" is defined in Section 13(d) of the Securities Exchange
Act of 1934), in a transaction or series of related transactions, of the
beneficial ownership of capital stock representing thirty percent (30%) or more
of the outstanding voting rights of such Limited Partner.

                  (b) The purchase price for any Partnership Interest which the
Partnership purchases upon exercise of its option pursuant to Section 9.6(a)
shall be the fair market value of such Partnership Interest on a going concern
basis as determined by a reputable investment banking firm. Such firm shall be
selected by the Partnership within 30 days after the exercise of the option
hereunder and shall be reasonably acceptable to each of the Partners. The
determination by such investment banking firm of the fair market value of the
Partnership Interests shall be made as of the date of the exercise of the option
to purchase such Partnership Interests and such determination shall be final and
binding on all parties to this Agreement. The Partners and the Partnership shall
use their respective best efforts to cause the determination of fair market
value to be completed within 60 days after the appointment of the investment
banking firm.

                  (c) The Partnership shall have the right, at any time prior to
the exercise of its option hereunder, to assign its option and all of its other
rights under this Section 9.6 to any Limited Partner other than the Affected
Partner pro rata in proportion to each such Limited Partner's Partnership
Interest and, upon notice of such assignment by the Partnership, the Affected
Partner shall be obligated to sell its Partnership Interest to such assignee
upon exercise of the option assigned pursuant thereto.

                  9.7 Closing. The closing of the purchase and sale of a
Partnership Interest pursuant to Section 9.3, 9.4 or 9.6 shall take place at the
principal office of the Partnership (or such other location as may be mutually
agreed upon by the Partnership

                                       22




and the Partners), within 30 days after notice of the exercise by the
Partnership or the Non-Selling Partner of its right to purchase the Offered
Interest pursuant to Section 9.3 or 9.4, as the case may be, or, in the case of
a purchase under Section 9.6, within 30 days after the final determination of
the fair market value of the Partnership Interest. At closing the seller shall
deliver to the purchaser of the Partnership Interest an assignment of such
interest, free and clear of any lien, claim, charge, pledge, security interest
or encumbrance whatsoever, and the purchaser shall deliver to the seller
consideration therefor at the price and on the terms of the Bona Fide Offer (or
the reasonable economic equivalent thereof pursuant to Section 9.5 above) or at
the price fixed by the investment banking firm pursuant to Section 9.6, as the
case may be. The seller shall warrant to the purchaser that the interest being
transferred is free and clear of any lien, claim, charge, pledge, security
interest or encumbrance whatsoever.

                  9.8 Involuntary Transfers. In the event that the Partnership
Interest owned by any Limited Partner shall be subject to sale or other transfer
by reason of (i) bankruptcy or insolvency proceedings, whether voluntary or
involuntary, (ii) attachment or garnishment; or (iii) distraint, levy, execution
or other involuntary transfer, then such Limited Partner shall give the
Partnership and the other Partners written notice thereof promptly upon the
occurrence of such event, stating the terms of such proposed transfer, the
identity of the proposed transferee, the price or consideration, if readily
determinable, for which the Partnership Interest is proposed to be transferred,
and the number of the Partnership Interest to be transferred. After receipt of
such notice, or, failing such receipt, after the Partnership or any of other
Partners otherwise obtains actual knowledge of such proposed transfer, the
Partnership and the other Limited Partners (unless applicable law would
otherwise prohibit) shall have the same rights of first and second refusal as
are set forth in Sections 9.3 and 9.5 above, respectively; provided, however,
that if the nature of the event is such that no readily determinable
consideration is to be paid for the transfer of the Partnership Interest the
price to be paid shall be the book value thereof, as determined by the
Partnership in accordance with Generally Accepted Accounting Principles,
consistently applied.

                  9.9 Allocation of Distributions Subsequent to Assignment. All
Profits and Losses of the Partnership attributable to any Partnership Interest
acquired by reason of any Transfer of such Partnership Interest and any
distributions made with respect thereto shall be allocated (i) in respect of the
portion of the Partnership Year ending on the effective date of the Transfer, to
the transferor and (ii) in respect of subsequent periods, to the transferee. The
effective date of any Transfer permitted under this Agreement, subject to the
provisions of Section 9.12 below, shall be the close of business on the day the
Partnership is notified of the Transfer.

                                       23




                  9.10 Death, Incompetence, Bankruptcy, Liquidation or
Withdrawal of a Limited Partner. The death, incompetence, Bankruptcy,
liquidation or withdrawal of a Limited Partner shall not cause (in and of
itself) a dissolution of the Partnership, but the rights of such a Limited
Partner to share in the Profits and Losses of the Partnership, to receive
distributions as to assign its Interest pursuant to this Article 9, on the
happening of such an event, shall devolve on its beneficiary or other successor,
executor, administrator, guardian or other legal representative for the purpose
of settling its estate or administering its property, and the Partnership shall
continue as a limited partnership. Such successor or personal representative,
however, shall become a substituted limited partner only upon compliance with
the requirements of Section 9.13 hereof with respect to a transferee of a
Partnership Interest. The estate of a Bankrupt Limited Partner shall be liable
for all the obligations of the Limited Partner.

                  9.11 Satisfactory Written Assignment Required. Anything herein
to the contrary notwithstanding, both the Partnership and the General Partner
shall be entitled to treat the transferor of a Partnership Interest as the
absolute owner thereof in all respects, and shall incur no liability for
distributions of cash or other property made in good faith to it, until such
time as a written assignment or other evidence of the consummation of a Transfer
that conforms to the requirements of this Article 9 and is reasonably
satisfactory to the General Partner has been received by and recorded on the
books of the Partnership, at which time the Transfer shall become effective for
purposes of this Agreement.

                  9.12 Transferee's Rights. Any purported Transfer of a
Partnership Interest which is not in compliance with this Agreement is hereby
declared to be null and void and of no force and effect whatsoever. A permitted
transferee of any Partnership Interest pursuant to Section 9.1, 9.2, 9.3, 9.4,
9.8 or 9.10 hereof shall be entitled to receive distributions of cash or other
property from the Partnership and to receive allocations of the income, gains,
credits, deductions, profits and losses of the Partnership attributable to such
Partnership Interest after the effective date of the Transfer but shall not
become a Partner unless and until admitted pursuant to Section 9.13 hereof.

                  9.13 Transferees Admitted as Partners. The assignee or
transferee of any Partnership Interest shall be admitted as a Partner only upon
the satisfaction of the following conditions:

                  (a) A duly executed and acknowledged written instrument of
Transfer approved by the General Partner and either a copy of this Agreement
duly executed by the transferee or an instrument of assumption in form and
substance satisfactory to the General Partner setting forth the transferee's
agreement to be bound by the provisions of this Agreement have been delivered to
the Partnership.

                                       24




                  (b) The transferee has paid any fees and reimbursed the
Partnership for any expenses paid by the Partnership in connection with the
Transfer and admission.

The effective date of an admission of a Partner and the withdrawal of the
transferring Partner, if any, shall be the first day which is the last business
day of a calendar month to occur following the satisfaction of the foregoing
conditions.

                                   ARTICLE 10

                                   DISSOLUTION

                  10.1 Events of Dissolution. The Partnership shall continue
until December 31, 2019, or such later date as the Partners may unanimously
agree, unless sooner dissolved upon the earliest to occur of the following
events, which shall cause an immediate dissolution of the Partnership:

                  (a) the sale, exchange or other disposition of all or
substantially all of the Partnership's assets;

                  (b) the withdrawal, resignation, filing of a certificate of
dissolution or revocation of the charter or Bankruptcy of the General Partner or
the occurrence of any other event which causes the General Partner to cease to
be a general partner of the Partnership under the Act (each an "Event of
Withdrawal"); or

                  (c) such earlier date as the Partners shall unanimously elect.

                  10.2 Final Accounting. Upon the dissolution of the Partnership

of dissolution.

                  10.3 Liquidation. Upon the dissolution of the Partnership as
provided in Section 10.1 hereof, the General Partner or, if there is no General
Partner, a person approved by a majority in interest of the remaining Partners,
shall act as liquidator to wind up the Partnership. The liquidator shall have
full power and authority to sell, assign and encumber any or all of the
Partnership's assets and to wind up and liquidate the affairs of the Partnership
in an orderly and business-like manner. All proceeds from liquidation shall be
distributed in the following orders of priority: (a) to the payment and
discharge of the debts and liabilities of the Partnership (other than
liabilities for distributions to Partners) and expenses of liquidation, (b) to
the setting up of such reserves as the liquidator may reasonably deem necessary
for any contingent liability of the Partnership (other than liabilities for
distributions to Partners), and (c) the balance to the Partners in accordance
with their positive Capital Accounts after

                                       25




adjustment to reflect all Profit and Loss for the Partnership Year in which such
liquidation occurs.

                  10.4 Cancellation of Certificate. Upon the completion of the
distribution of Partnership assets as provided in Section 10.3 hereof, the
Partnership shall be terminated and the person acting as liquidator shall cause
the cancellation of the Certificate (as amended) and shall take such other
actions as may be necessary or appropriate to terminate the Partnership.

                                   ARTICLE 11

                             AMENDMENTS TO AGREEMENT

                  Without the written approval of each of the Partners, no
amendment shall be made to this Agreement. The General Partner shall give
written notice to all partners promptly after any amendment has become
effective.

                                   ARTICLE 12

                                   ARTICLE 13

                           INVESTMENT REPRESENTATIONS

                  13.1 Investment Purpose. Each Limited Partner represents and
warrants to the Partnership and to each other Partner that it has acquired its
limited partner interest in the Partnership for its own account, for investment
only and not with

                                       26



a view to the distribution thereof, except to the extent provided in or
contemplated by this Agreement.

                  13.2 Investment Restriction. Each Partner recognizes that (a)
the limited partner interests in the Partnership have not been registered under
the Securities Act of 1933, as amended (the "Securities Act"), in reliance upon
an exemption from such registration, and agrees that it will not sell, offer for
sale, transfer, pledge or hypothecate its limited partner interest in the
Partnership (i) in the absence of an effective registration statement covering
such limited partner interest under the Securities Act, unless such sale, offer
of sale, transfer, pledge or hypothecation is exempt from registration for any
proposed sale, and (ii) except in compliance with all applicable provisions of
this Agreement, and (b) the restrictions on transfer imposed by this Agreement
may severely affect the liquidity of an investment in limited partner interests
in the Partnership.

                                   ARTICLE 14

                               GENERAL PROVISIONS

                  14.1 Entire Agreement. This Agreement constitutes the entire

and supersedes any prior agreement or understanding among the parties hereto
with respect to the subject matter hereof.

                  14.2 Amendment Waiver. Except as provided otherwise herein,

assigns.

                  14.5 Separability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

                                       27




                  14.6 Headings. The section and other headings contained in
this Agreement are for reference purposes only and shall not affect the meaning
or interpretation of this Agreement.

                  14.7 No Third-Party Rights. Nothing in this Agreement shall be
deemed to create any right in any person not a party hereto (other than the
permitted successors and assigns of a party hereto) and this Agreement shall not
be construed in any respect to be a contract in whole or in part for the benefit
of any third party (except as aforesaid).

                  14.8 Waiver of Partition. Each Partner, by requesting and
being granted admission to the Partnership, is deemed to waive until termination
of the Partnership any and all rights that it may have to maintain an action for
partition of the Partnership's assets.

                  14.9 Nature of Interests. All Partnership property, whether
real or personal, tangible or intangible, shall be deemed to be owned by the
Partnership as an entity, and none of the Partners shall have any direct
ownership of such property.

                  14.10 Power of Attorney. Each of the Partners does hereby
constitute and appoint the General Partners as its true and lawful
representative and attorney-in-fact, in its name, place and stead to make,
execute, sign and file any amendment to the Certificate which may be required

agency thereof or which the General Partner may deem necessary or appropriate to
effectuate, implement and continue the valid and subsisting existence and
business of the Partnership.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement on the day and year first above written.
