otherwise required shall be in default under this Agreement; provided, however,
that a Partner that fails to make an Additional Capital Contribution shall not
be entitled, at a later time, to make an Additional Capital Contribution in
respect of the amount that such Partner had previously failed to contribute,
unless permitted to do so by the Executive Committee with each Representative

         The foregoing provisions and the other provisions of this Agreement

set forth in this Agreement, no Partner shall have the right to demand or

Account, and, except as expressly set forth in this Agreement, no Partner shall
be entitled to receive any interest on its outstanding Capital Account balance.

SECTION 5.5 PERCENTAGE INTERESTS.

                              ARTICLE 6 - PARTNERS

SECTION 6.1 POWERS AND AUTHORITY OF THE PARTNERS.

         (a) Subject to the restrictions otherwise set forth in this Agreement
(including, without limitation, the restrictions set forth in Sections 6.2, 6.3
and 6.4) and in any Budget and any Operating Plan, the affairs of the
Partnership shall be managed and supervised solely by the Partners, by means of
and through a committee of Representatives appointed pursuant to Section 6.2(b)
(the "Executive Committee"). Subject to the terms and provisions of this
Agreement (including, without limitation, the restrictions set forth in Sections
6.2, 6.3 and 6.4), each of the Partners shall have all of the powers of a
general partner, including all powers necessary, advisable, convenient,
incidental or appropriate to carry out the purposes of the Partnership.

SECTION 6.2 EXECUTIVE COMMITTEE.

         (a) The Partners shall be solely responsible for and are authorized to
conduct and control the affairs of the Partnership. They shall act through the
Executive Committee. The Administrative Partner shall conduct and/or supervise
the day-to-day activities of the Partnership subject to such limitations and
directions as shall be adopted by the Executive Committee.

         (b) The Executive Committee shall consist of representatives (each a
"Representative") of the Partners appointed by the Partners based upon the
aggregate Percentage Interest held by each Partner. Any Partner that holds an
aggregate Percentage Interest of 30% or greater shall be entitled to appoint two
individuals to the Executive Committee as Representatives of such Partner. If
the aggregate Percentage Interest held by any Partner is less than 30%, then
such Partner shall be entitled to appoint one individual to the Executive
Committee as the Representative of such Partner so long as such Partner holds an
aggregate Percentage Interest of 20% or greater. Any Partner that holds an
aggregate Percentage Interest of less than 20% shall not be entitled to appoint
any Representatives to the Executive Committee and shall, consequently, have no
representation on the Executive Committee. An individual appointed by a Partner
as a Representative shall be a partner, officer, director, majority equity
holder, or employee of the Partner appointing such Representative.
Representatives shall be authorized to act on behalf of the Partners and to
approve any matters which are required to be approved hereunder. Any
Representative of a Partner may be removed and another Representative
substituted therefor by such Partner from time to time as designated in a Notice
to such effect to the other Partner so long as the Partner giving such Notice
has the ability to appoint at least one Representative to the Executive
Committee. The Executive Committee shall meet at least quarterly and shall be
required to meet upon ten (10) Business Days prior Notice given to all
Representatives from any Representative. Meetings shall be held at the
Partnership's offices, or at such other place as the Representatives shall
agree. So long as the aggregate Percentage Interest held by a Partner shall not
be less than 40%: (i) a majority of the Representatives shall constitute a
quorum; and (ii) a unanimous vote of such quorum, which shall

                                      -14-
<PAGE>
include the affirmative vote of at least one Representative of each Partner,
shall, constitute the legally binding and lawful act of the Partnership as to
any matter voted upon. In the event that the aggregate Percentage Interest held
by any Partner shall be less than 40%: (i) the presence of Representatives
constituting a majority of the Percentage Interest of the aggregate Percentage
Interest of all Partners shall constitute a quorum; and (ii) the affirmative
vote of Representatives constituting a majority of the Percentage Interest of
the aggregate Percentage Interest of all Partners shall constitute the legally
binding and lawful act of the Partnership as to any matter voted upon. A
Representative shall be considered present for purposes of any required vote if
participating in, or represented at such meeting either in person, or by proxy
or authorized representative, including, but not limited to, a telephonic
communication by which all Representatives attending such meeting may hear and
be heard. A written record of minutes of all meetings of the Executive Committee
and all resolutions of or decisions made by the Executive Committee shall be
made and shall be kept in the records of the Partnership. Minutes and/or
resolutions approved by the Executive Committee shall be binding and conclusive
evidence of the decisions reflected therein and any authorizations granted
thereby. No Representative shall be entitled to receive any salary or other
remuneration or expense reimbursement from the Partnership for his services as a
Representative. The Representatives as such shall not be deemed to be general
partners of the Partnership and shall not be generally or personally liable for
the debts or obligations of the Partnership.

            Notwithstanding the foregoing, so long as a Partner holds an
aggregate Percentage Interest of 30% or greater, action with respect to all
Substantive Decisions shall require the affirmative vote of at least one
Representative of each such Partner. For this purpose, "Substantive Decisions"
shall mean the following:

                  (i) appointment, removal and compensation of officers, if any,
         of the Partnership; and

                  (ii) appointment or removal of the Administrative Partner.

         Notwithstanding the foregoing, so long as a Partner holds an aggregate
Percentage Interest of 20% or greater, action with respect to all Major
Decisions shall require the affirmative vote of at least one Representative of
each such Partner. For this purpose, "Major Decisions" shall mean the following:

                  (i) other than as set forth in Section 9.6, the sale of equity
         interests in the Partnership, the sale of all or substantially all of
         the Partnership Assets, the sale of the Plant, the sale of the CT, or
         the sale of any or all of the foregoing;

                  (ii) the liquidation, merger or recapitalization of the
         Partnership and financing and refinancing decisions related to either
         of them;

                                      -15-
<PAGE>
                  (iii) approval of any Budget (and any related Additional
         Capital Contribution) and approval of the incurrence by the Partnership
         of any indebtedness for borrowed money;

                  (iv) any capital expenditure of the Partnership (whether or
         not included within any Budget);

                  (v) approval of any Development Option (and any related
         Additional Capital Contribution);

                  (vi) distributions from the Partnership, other than
         distributions required under Section 5.1, Section 9.6 or ARTICLE 8;

                  (vii) amendments to this Agreement or the Operating Agreement;

                  (viii) commencement or settlement of any material litigation
         by the Partnership; and

                  (ix) the establishment of reserves in excess of those
         recommended by accounting or banking standards.

Any reference to action required or permitted to be taken by the Executive
Committee pursuant to this Agreement shall mean actions taken in accordance with
this Section 6.2(b).

         (c) The Executive Committee may establish other committees or organize
other work groups as it may deem to be in the best interests of the Partnership
and determine the size, personnel and delegated powers or responsibilities
thereof.

         (d) Notwithstanding any provision of this Agreement to the contrary,
any third party dealing with the Partnership shall be entitled to rely on a
certification and/or representation of either Partner stating that the Partner
has the authority pursuant to this Agreement to take any specified action or to
execute and deliver any specified agreement, instrument or other document, but
the foregoing shall not relieve such Partner from any liability that it may have
to the Partnership or the Partners for acting without authority under this
Agreement.

SECTION 6.3 ADMINISTRATIVE PARTNER.

         The Executive Committee may designate a Partner (the "Administrative
Partner") to act as the administrative partner of the Partnership and implement
the decisions of the Executive Committee. UGI GP shall be the initial
Administrative Partner. Subject to the policies and directives of the Executive
Committee, the Administrative Partner shall be responsible for supervising the
operation and management of the Partnership and the Partnership Assets. Subject
to the limitations set forth in this Agreement or in any Budget or Operating
Plan, the Administrative Partner shall have the power and authority to enter
into contracts on behalf of

                                      -16-
<PAGE>
the Partnership, to execute and deliver all necessary instruments and documents
and to make expenditures under and in accordance with such documents and
instruments or otherwise as are required to implement any Budget and Operating
Plan.

SECTION 6.4 COMPENSATION TO THE PARTNERS AND RELATED ENTITIES.

         (a) No fees or other compensation or reimbursement for costs incurred
shall be payable to any Partner for performance of services to or on behalf of
the Partnership, except as provided in this Section 6.4 or Section 6.5.

         (b) The Partnership shall pay, or shall reimburse the Partners for
payment of, all of the Partnership's ordinary and necessary expenses including
out-of-pocket expenses, as determined proper by the Executive Committee or in
accordance with the procedures and guidelines set forth in any Budget or
Operating Plan. Costs paid or incurred by any Partner in its capacity as
Partner, including but not limited to payments for legal or accounting services
rendered to such partner in its particular capacity shall be for the account of
such partner and shall not be reimbursed.

         (c) Neither the Administrative Partner nor any member of the Executive
Committee shall receive a fee in connection with its service as either the
Administrative Partners of a member of the Executive Committee. The foregoing
shall not restrict or limit the right of a Partner or any Affiliate thereof to
receive fees under the Operating Agreement.

SECTION 6.5 EXCULPATION AND INDEMNIFICATION.

         (a) No Partner, any Related Entity of such Partner, or any
representative of such Partner or such Related Entity (including the
Representatives and the Administrative Partner), acting on behalf of the
Partnership in connection with any business or activity of the Partnership,
shall be liable to the Partnership or to any Partner for any loss arising out of
or in connection with the management, operation or conduct of the Partnership
Affairs, except by reason of bad faith, willful misconduct, fraud or gross
negligence in respect of the matter on which the claim is based. The
Partnership, to the fullest extent permitted by applicable law, shall indemnify
and hold harmless each person or entity indemnified as provided above in this
Section 6.5(a) in its capacity as such, from and against any and all claims,
costs, losses, damage, expenses (including, without limitation, the expense of
defending, investigating or preparing to defend any claim) or liabilities
(including, but not limited to, reasonable attorneys' fees) suffered or
sustained by such indemnified person by reason of any acts performed or omitted
to be performed by such indemnified person on behalf of the Partnership or in
furtherance of the interest of the Partnership, except, with respect to any
indemnified party by reason of bad faith, willful misconduct, fraud or gross
negligence in respect of the matter on which the claim is based.

                                      -17-
<PAGE>
         (b) No claim, action or proceeding, or any appeal therefrom which is
subject to the provisions of Section 6.5(a) shall be settled by the Partnership
without the consent of the person or entity affected thereby, unless the
settlement of such claim, action or proceeding requires solely the payment of
money. Notwithstanding the foregoing, if the Partnership is also a defendant in
any such claim, action, proceeding or appeal, the Partnership may enter into any
settlement for itself without the consent of any other defendant. The
Partnership shall not be liable for any claim settled without its consent, which
consent may not be unreasonably withheld.

         (c) To the extent that, at law or in equity, a person or entity
indemnified pursuant to Section 6.5(a) has duties (including fiduciary duties)
and liabilities relating thereto to the Partnership or to the Partners, such
indemnified person acting under this Agreement or otherwise shall not be liable
to the Partnership or to any Partner for its good faith reliance on the
provisions of this Agreement. The provisions of this Agreement, to the extent
that they expand or restrict the duties and liabilities of an indemnified person
otherwise existing at law or in equity, are agreed by the Partners to replace
such other duties and liabilities of such indemnified person.

                 ARTICLE 7 - ALLOCATIONS OF PROFITS AND LOSSES

SECTION 7.1 PROFITS AND LOSSES.

         (a) After giving effect to the mandatory allocations set forth in
Section 7.2. Profits for any Fiscal Year shall be allocated to the Partners in
the following order of priority: (i) first, to the Partners, to the extent of
and in proportion to the amounts, if any, by which cumulative prior allocations
of Profit to each Partner under this clause are less than cumulative prior
allocations of Loss to each such Partner pursuant to the last sentence of
Section 7.1(b); (ii) second, to the Partners, to the extent of and in proportion
to the amounts, if any, by which cumulative prior allocations of Profit to each
Partner under this clause are less than cumulative prior allocations of Loss to
each such Partner pursuant to the first sentence of Section 7.2, and (iii)
thereafter, to the Partners, pro rata in accordance with their Percentage
Interests.

         (b) After giving effect to the mandatory allocations set forth in
Section 7.2, Losses for any Fiscal Year shall be allocated to the Partners pro
rata in accordance with their Percentage Interests. To the extent that any
Partner has or would have, as a result of an allocation of Loss (or item
thereof), an Adjusted Capital Account deficit such Loss (or item thereof) shall
be allocated to the other Partners, pro rata in accordance with their relative
Percentage Interests, but in a manner that will not produce an Adjusted Capital
Account deficit as to such Partners or, if such allocation would result in all
Partners having an Adjusted Capital Account deficit, such loss shall be
allocated to the Partners, pro rata in accordance with their relative Percentage
Interests.

SECTION 7.2 MANDATORY ALLOCATION RULES.

         Notwithstanding any other provisions of this Agreement to the contrary,
the

                                      -18-
<PAGE>
following mandatory allocations shall be made in the following order:

         (a)      (i) If there is a net decrease in Partnership Minimum Gain
during any Fiscal Year, then, subject to the exceptions set forth in Regulations
Sections 1.704-2(f)(2), (3), (4) and (5), each Partner shall be specially
allocated items of Partnership income and gain for such Fiscal Year (and, if
necessary, subsequent Fiscal Years) in an amount equal to such Partner's share
of the net decrease in Partnership Minimum Gain, as determined in accordance
with Regulations Section 1.704-2(g). Allocations pursuant to the previous
sentence shall be made in proportion to the respective amounts required to be
allocated to each Partner pursuant thereto. The items to be so allocated shall
be determined in accordance with Regulations Section 1.704-2(f). This Section
7.2(a)(i) is intended to comply with the minimum gain charge back requirement in
such Section of the Regulations and shall be interpreted consistently therewith.

                  (ii) If there is a net decrease in Partner Minimum Gain
         attributable to a Partner Nonrecourse Debt during any Fiscal Year,
         then, subject to the exceptions set forth in Regulations Section
         1.704-2(i)(4), each Partner who has a share of the Partner Minimum Gain
         attributable to such Partner Nonrecourse Debt, determined in accordance
         with Regulations Section 1.704-2(i)(5), shall be specially allocated
         items of Partnership income and gain for such Fiscal Year (and, if
         necessary, subsequent Fiscal Years) in an amount equal to such
         Partner's share of the net decrease in Partner Minimum Gain
         attributable to such Partner Nonrecourse Debt, determined in accordance
         with Regulations Section 1.704-2(i)(4). Allocations pursuant to the
         previous sentence shall be made in proportion to the respective amounts
         required to be allocated to each Partner pursuant thereto. The items to
         be so allocated shall be determined in accordance with Regulations
         Section 1.704-2(i)(4). This Section 7.2(a)(ii) is intended to comply
         with the minimum gain charge back requirement in such Section of the
         Regulations and shall be interpreted consistently therewith.

         (b) In the event any Partner receives any adjustments, allocations, or
distributions described in Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or
(6) that cause or increase an Adjusted Capital Account deficit of such Partner,
items of Partnership income and gain shall be specially allocated to such
Partner in an amount and manner sufficient to eliminate, to the extent required
by the Regulations, the Adjusted Capital Account deficit of such Partner as
quickly as possible. This Section 7.2(b) is intended to comply with the
qualified income offset requirement in Regulations Section 1.704-1(b)(2)(ii)(d)
and shall be interpreted consistently therewith.

         (c) Any Partner Nonrecourse Deductions for any Fiscal Year or other
period shall be allocated to the Partner who bears the economic risk of loss
with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse
Deductions are attributable in accordance with Regulations Section
1.704-2(i)(2).

                                      -19-
<PAGE>
         (d) To the extent an adjustment to the adjusted tax basis of any
Partnership Asset pursuant to Code Section 734(b) or Code Section 743(b) is
required, pursuant to Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into
account in determining Capital Accounts, the amount of such adjustment to the
Capital Accounts shall be treated as an item of gain (if the adjustment
increases the basis of the asset) or loss (if the adjustment decreases such
basis) and such gain or loss shall be allocated to the Partners in a manner
consistent with the manner in which their Capital Accounts are required to be
adjusted pursuant to such Section of the Regulations.

         (e) All items of deduction or loss, if any, attributable to the
contributions of the Partners shall be allocated to such Partners pro rata in
accordance with their relative Percentage Interests.

         (f) Any Profits or Losses (or, if necessary, items of income, gain,
loss or deduction) recognized on or after the dissolution of the Partnership or
otherwise on or after the disposition of substantially all of the Partnership
assets shall be allocated among the Partners to the extent of and in proportion
to the amounts required to cause the Capital Account balance of each Partner to
be in proportion to its Percentage Interest.

         (g) The allocations set forth in Sections 7.2(a), 7.2(b) and 7.2(c)
above (the "Regulatory Allocations") are intended to comply with certain
requirements of Regulations Section 1.704-1(b). The Regulatory Allocations shall
be taken into account for purposes of equitably adjusting subsequent allocations
of Profits and Losses and items of income, gain, loss, and deduction among the
Partners so that, to the extent possible, the net amount of such allocation of
Profits and Losses and other items to each Partner shall be equal to the net
amount that would have been allocated to each such Partner if the Regulatory
Allocations had not occurred.

SECTION 7.3 OTHER ALLOCATION RULES.

         (a) For purposes of determining the Profits, Losses, or any other items
allocable to any period, Profits, Losses and any such other items shall be
determined on a daily, monthly, or other basis, as determined by the Partners
using any permissible method under Code Section 706 and the Regulations
thereunder.

         (b) Except as otherwise provided in this Agreement, all items of
Partner income, gain, loss, deduction, and any other allocations not otherwise
provided for shall be divided among the Partners in the same proportions as they
share Profits and Losses, as the case may be, for the Fiscal Year.

         (c) The Partners are aware of the income tax consequences of the
allocations made by this ARTICLE 7 and hereby agree to be bound by the
provisions thereof in reporting their shares of Partnership income and loss for
income tax purposes.

                                      -20-
<PAGE>
         (d) To the extent permitted under Regulations Section 1.704-2(h)(3),
the Partnership shall treat a distribution of proceeds of a Nonrecourse
Liability as a distribution that is not allocable to an increase in Partnership
Minimum Gain.

SECTION 7.4 TAX ALLOCATIONS.

         (a) Except as otherwise provided in this Section 7.4, each item of
income, gain, loss and deduction as computed for federal income tax purposes,
shall be allocated among the Partners in the same manner as its correlative item
of "book" income, gain, loss or deduction is allocated pursuant to Sections 7.1
and 7.2 above.

         (b) In accordance with Code Section 704(c) and the 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 into account any variation between
the adjusted basis of such property to the Partnership for federal income tax
purposes and its initial Gross Asset Value in accordance with Regulations
Section 1.704-3(b).

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

         (d) Any elections or other decisions relating to such allocations shall
be made by the Tax Matters Partner with the advice of the Accountants and tax
counsel for the Partnership in any manner that reasonably reflects the purpose
and intention of this Agreement. Allocations pursuant to this Section 7.4 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 pursuant to any provision of this
Agreement.

                      ARTICLE 9 - TRANSFER OF PARTNERSHIP
                         INTERESTS; DEVELOPMENT OPTIONS

SECTION 9.1 PROHIBITED TRANSFERS; TRANSFERS TO AFFILIATES.

            No Partner may, without the prior consent of all other Partners,
sell, pledge, hypothecate, convey or otherwise transfer (collectively a
"Transfer") all or any part of its Partnership Interest (or equity interests in
a Partner) (the "Offered Interest") to any other Partner or third party without
first complying with the provisions of Section 9.2 and Section 9.3; provided,
however, that a Partner may Transfer any Offered Interest without the prior
consent of any other Partner and without the need to comply with Section 9.2 or
Section 9.3 to any Affiliate of such Partner so long as (i) the transferee
complies with the provisions of Section 10.1 and (ii) the Transfer would have no
materially adverse effect on the Partnership, any Partner or the operation of
the Plant or the CT, including, without limitation, any effect on the regulatory
status of the Plant or the CT or any increased permitting or licensing burden on
the Partnership or any Partner. A permitted Transfer under this Section 9.1
shall not relieve the transferor of any of its obligations prior to the
Transfer. Each Partner shall cooperate with all other Partners with respect to
transactions contemplated under this Section 9.1 that have either been approved
as provided in this Section 9.1 or otherwise do not require approval, and shall
do, execute and deliver all instruments, documents, consents, amendments and
acts necessary to consummate such transactions contemplated under this Section
9.1.

SECTION 9.2 RIGHT OF REFUSAL.

                                      -22-
<PAGE>
            Subject to Section 9.1, in the event that a Partner (the "Selling
Partner") shall at any time subsequent to the date hereof receive a bona fide
offer from a third party that is not an Affiliate in respect of the sale of all
or any portion of its Partnership Interest (or interests in the entity holding
such Partnership Interest), the Selling Partner shall give the other Partners
(the "Remaining Partners") notice (the "Sale Notice") of the terms and
conditions of each such bona fide offer upon which the Selling Partner is
willing to sell such Partnership Interest. Each Remaining Partner shall have the
right, exercisable by delivering written notice to the Selling Partner within
ten (10) days after the date of the Sale Notice, to purchase the portion of the
Selling Partner's Partnership Interest (or interests in the entity holding such
Partnership Interest) sought to be sold upon the terms and conditions contained
in the Sale Notice. If the amount of Partnership Interests (or interests in the
entity holding such Partnership Interest) sought to be purchased by the
Remaining Partners exceeds the amount sought to be sold by the Selling Partner,
each Remaining Partner electing to exercise its right pursuant to this Section
9.2 shall be deemed to have exercised its right to purchase only such portion of
the Partnership Interests sought to be sold as such Remaining Partner's
Percentage Interest bears to the aggregate Percentage Interests of all Remaining
Partners exercising. If the amount of Partnership Interests (or interests in the
entity holding such Partnership Interest) sought to be purchased by the
Remaining Partners is less than the amount sought to be sold by the Selling
Partner, the Selling Partner shall be free to sell any remaining portion of such
Partnership Interest to a third party that is not an Affiliate on the same terms
and conditions as set forth in the Sale Notice. The Selling Partner and each
Remaining Partner electing to exercise its right pursuant to this Section 9.2
shall thereupon enter into a Partnership Interest purchase agreement acceptable
to the Selling Partner which shall contain the same terms and conditions set
forth in the Sale Notice. In the event that any Remaining Partner fails to
exercise its right as aforesaid within ten (10) days of the date of receipt of
the Sale Notice, such Remaining Partner shall be deemed to have waived its
rights under this Section 9.2 with respect to the Selling Partner's Partnership
Interests (or interests in the entity holding such Partnership Interest, as the
case may be) sought to be sold, and the Selling Partner shall have the absolute
right to sell the Partnership Interests (or interests in the entity holding such
Partnership Interest, as the case may be) as set forth in the Sale Notice to any
other person or entity and such Remaining Partner shall have no further rights
with respect to the Partnership Interests as set forth in the Sale Notice;
provided, however, that in the event that such third party sale is not
consummated within six (6) months after the date of the Sale Notice, or if there
is any material change proposed to be made in the terms or conditions of such
sale, then the Selling Partner shall be required to provide a new Sale Notice to
the Remaining Partners, and such Remaining Partners shall have the right to
purchase that portion of the Selling Partner's Partnership Interest as is being
offered for sale, all as set forth in this Section 9.2. Any Remaining Partner
which fails to exercise its rights as aforesaid within ten (10) days of the
receipt of any such Sale Notice shall be deemed to have waived its rights under
this Section 9.2, but only with respect to the individual transaction described
in such Sale Notice.

SECTION 9.3 RIGHT OF CO-SALE.

                                      -23-
<PAGE>
         (a) Subject to Section 9.1, in the event that the Selling Partner
wishes to sell all or any portion of its Partnership Interest (or interests in
the entity holding such Partnership Interest) to a third party, the Selling
Partner shall give the Remaining Partners a Sale Notice of its desire to do so,
which Sale Notice shall state the price, measured in dollars for the Partnership
Interests of the Selling Partner sought to be sold and the terms of the Offer,
including the date, if available, when such proposed sale is to be consummated.
Each Remaining Partner shall have the right (the "Co-Sale Right") to sell a pro
rata share of the Partnership Interests owned by such Remaining Partner as
follows: at least thirty (30) days prior to any sale of Partnership Interests by
the Selling Partner, the Selling Partner shall notify each Remaining Partner in
writing (the "Notice of Offer") of its determination to sell Partnership
Interests to one or more third parties (the "Purchasers"). The Notice of Offer
shall name the person or entity acquiring such shares and set forth the terms
and conditions of such sale, including the price, payment terms and proposed
date of consummation of the transaction.

         (b) Each Remaining Partner shall have twenty (20) days from the date of
receipt of the Notice of Offer (the "Co-Sale Right Period") to notify the
Selling Partner of its election to sell Partnership Interests to the Purchaser
upon the same terms and conditions which the Selling Partner has agreed to sell
its Partnership Interests. If any Remaining Partner elects to exercise its
Co-Sale Right, with respect to any sale of Partnership Interests by a Partner,
subject to the additional right granted in (c) of this Section 9.3, the
aggregate amount of Partnership Interests which the Remaining Partner shall have
the right to sell shall be not greater than the amount of Partnership Interests
set forth in the Notice of Offer, multiplied by a fraction, the numerator of
which is the amount of Partnership Interests of such Remaining Partner and the
denominator of which is the sum of the amount of Partnership Interests of each
Remaining Partner participating in the sale, plus the Partnership Interests of
the Selling Partner.

         (c) Each of the Remaining Partners shall have the right of
over-allotment such that if any of the Remaining Partners fails to exercise its
rights under paragraph (b) to sell its pro rata portion Partnership Interests to
be sold, or any portion thereof, the other Remaining Partners may (by exercising
their over-allotment right within the Co-Sale Right Period) sell a pro rata
portion of such amount to the Purchaser. The calculation of the pro rata rights
of each Remaining Partner shall be as of the date of the Notice of Offer and
shall be based on the ratio of the amount of such Remaining Partner's
Partnership Interest to the total amount of outstanding Partnership Interests of
each of the Remaining Partners participating in the Sale.

         (d) Any Remaining Partner which fails to notify the Selling Partner
during the Co-Sale Right Period of its election to sell its pro rata share, or
any lesser amount, to the Purchaser, shall be deemed to have declined to sell
any of its Partnership Interests only with respect to the transaction described
in the Notice of Offer.

         (e) Subject to compliance by the Selling Partner with the provisions of
Section 9.3, the Selling Partner may sell its Partnership Interests to the
Purchaser on the terms specified in the Notice of Offer, provided that if such
sale is not consummated within six (6)

                                      -24-
<PAGE>
months of the date of the Notice of Offer, the Selling Partner shall issue a new
Notice of Offer to the Remaining Partners pursuant to this Section 9.3 and again
comply with the provisions hereof with regard to such transaction.

SECTION 9.4 CONDITIONS APPLICABLE TO TRANSFERS.

         (a) COMPLIANCE WITH LAWS, ETC.

                  (i) Notwithstanding anything to the contrary contained in this
         Agreement, any Transfer of any Partner's Partnership Interest shall be
         made in full compliance with (A) all applicable statutes, laws,
         ordinances, rules and regulations of all federal, state and local
         governmental bodies, agencies and subdivisions having jurisdiction over
         the Partnership and the Partnership Assets, (B) the provisions of this
         Agreement, and (C) any agreements or loans of the Partnership, so that
         the operation of the Partnership and the Partnership Assets can
         continue without interruption and without violation of any applicable
         law, or if any approval or consent is required in connection with any
         such Transfer, the Responsible Partner (hereinafter defined) shall
         promptly make such filing or application or obtain such approval or
         consent at its sole expense, and shall reimburse the Partnership for
         any costs or expenses (including attorneys fees) incurred by the
         Partnership in connection with any filing, application, approval or
         consent.

                  The "Responsible Partner" shall be the transferring Partner;
         provided, however, that should such transferor fail or refuse to
         perform hereunder, the Administrative Partner, acting on behalf of the
         remaining Partners, at the cost and expense of such transferor, shall
         act as "Responsible Partner" hereunder.

                  (ii) Notwithstanding any provision hereof to the contrary, no
         Transfer shall be made pursuant to this ARTICLE 9 to any Foreign Person
         unless and until the transferee agrees in writing in advance of the
         Transfer that (A) the Partnership may comply with any and all income
         and other withholding obligations that may be imposed on the
         Partnership without regard to other provisions of this Agreement that
         may otherwise govern the transferee's rights to its share of
         Partnership income and loss and to receive distributions from the
         Partnership; and (B) the transferee shall indemnify and hold the
         Partnership and the non-transferring Partners harmless from and against
         any and all expense or liability that is or may be imposed on the
         Partnership or the non-transferring Partners attributable to or arising
         out of such Transfer because of such status of the transferee. Any
         agreement of a transferee Partner required by this Section 9.4(a) shall
         be in such form and shall contain such additional provisions as the
         Partners in the exercise of reasonable discretion shall request as a
         condition precedent to such Transfer.

                                      -25-
<PAGE>
         (b) INSTRUMENTS OF TRANSFER.

         Notwithstanding anything to the contrary contained in this Agreement,
no change in ownership of the Partnership Interest of any Partner shall be
binding upon the other Partners or the Partnership unless and until (i) true
copies of the instruments of transfer executed and delivered pursuant to or in
connection with such Transfer shall have been delivered to the Administrative
Partner, (ii) the transferee shall have delivered to the Administrative Partner
an executed and acknowledged assumption agreement, in form and substance
reasonably satisfactory to counsel to the Partnership, pursuant to which the
transferee assumes from and after the date of the Transfer all the obligations
of the transferor thereunder thereafter accruing, makes all representations,
warranties and covenants as were made pursuant to ARTICLE 13 by the transferor,
and agrees to be bound by all the provisions of this Agreement, (iii) the
transferee shall have executed, acknowledged and delivered any instruments
required under the Act or the laws of any State in which the Partnership is
authorized to do business to effect such Transfer and its admission to the
Partnership, and (iv) unless waived by the Partners, the Partnership shall have
received an opinion of counsel as provided in Section 9.4(c) if the Transfer is
to any person or entity that is not at the time a Partner. Upon the execution
and delivery of such assumption agreement, the transferor shall have no further
obligation hereunder thereafter accruing except that the transferor shall remain
primarily liable for all accrued obligations (as of the date of Transfer) of the
transferor under this Agreement notwithstanding any Transfer pursuant to this
ARTICLE 9.

         (c) OPINION OF COUNSEL.

         If a Transfer is proposed to any person or entity that is not at the
time a Partner, then, prior to any such Transfer, the transferring Partner shall
give a notice to the Partnership setting forth the material terms and conditions
of such Transfer, the name of the proposed transferee and the name of its and/or
the transferee's counsel (which counsel shall be reasonably satisfactory to
counsel for the Partnership), and there shall be delivered to the Partnership an
opinion of counsel to the transferring Partner or transferee, reasonably
satisfactory in form and substance to counsel for the Partnership, with
reasonable qualifications (including, but not limited to, basing such opinion on
affidavits of the transferor and/or the transferee) to the effect that the
proposed Transfer shall not (i) result in the violation of the Securities Act of
1933 or any other applicable federal or state laws or the order of any court
having jurisdiction over the Partnership or require registration of the
Partnership Interest to be transferred under the Securities Act of 1933 as then
in force or the taking of any similar action under any similar Federal or state
law then in force; (ii) result, directly or indirectly, in a termination of the
Partnership under Code Section 708 or, if such termination occurs, such
termination would not have a material and adverse effect on the Partners; (iii)
cause the Partnership to become "publicly traded" for purposes of Code Section
7704; or (iv) cause the classification of the Partnership as a partnership for
purposes of the Code to be lost or adversely affected.

                                      -26-
<PAGE>
         The transferring Partner and the transferee shall pay to the
Partnership all costs incurred by the Partnership as a result of such Transfer,
and shall indemnify the Partnership (in a manner which is reasonably
satisfactory to the Partnership) for any such costs which are or may be incurred
by it thereafter as a result of such Transfer.

         (d) TRANSFEREES BY OPERATION OF LAW OR THIS AGREEMENT.

         If any party or entity acquires all or any part of a Partnership
Interest in violation of this ARTICLE 9 by operation of law or judicial
proceeding, the holder(s) of the affected interest shall have no right to take
action under this Agreement, and the Partner whose interest was so affected
shall be subject to the restrictions provided in Section 9.5. A transfer of the
equity securities of UGI Parent, UGID or Allegheny Parent (which is the sole
member of the Allegheny GP) shall not be deemed a Transfer hereunder.

         (e) EFFECTIVE DATE OF TRANSFERS.

         For financial and tax reporting purposes, every voluntary sale,
assignment or other transfer (as distinguished from the original issuance) of
any Partnership Interest or portion thereof shall be deemed to have occurred as
of the close of business on the day on which such event shall have in fact
occurred, and shall have no prior effect, and every involuntary sale, assignment
or transfer (whether by bequest, operation of law or any other method) of any
Partnership Interest shall be deemed to have occurred as of the close of
business on the day on which the Partnership shall have received evidence of
such transfer and shall have no prior effect.

SECTION 9.5 TRANSFERS VOID.

         Any attempted withdrawal, sale, assignment, pledge, transfer,
encumbrance, mortgage or other disposition, or substitution of a Partner, made
in violation of this Agreement shall be automatically void ab initio. If any
Partner makes or attempts to make a withdrawal, sale, assignment, pledge,
transfer, encumbrance, mortgage or other disposition or substitution in
violation of this Agreement, then unless such Partner is at the time the sole
General Partner, all of such Partner's rights hereunder to vote for or
participate in Partnership decisions shall be suspended until such violation is
cured.

SECTION 9.6 DEVELOPMENT OPTIONS; PUT AND CALL RIGHTS.

         (a) DEVELOPMENT OPTIONS.

                  (i) As set forth in this Agreement, "Development Options"
         shall mean opportunities to expand the generation capacity of the
         Partnership at the site of the Plant and the CT, at the Temple,
         Pennsylvania site of UGID's Affiliate UGI Utilities, Inc., at the site
         in Mt. Carmel, Pennsylvania of Foster-Wheeler's approximately 85 MW
         waste coal fired cogeneration unit, or at any other site

                                      -27-
<PAGE>
         where the Partners jointly agree in writing to enter into a new
         development project, or opportunities to create any new entity or
         entities for the purpose of creating additional generation capacity at
         any of the foregoing sites. Any Partner having knowledge of a
         Development Option shall bring the same to the attention of the
         Executive Committee for review. Subject to the provisions of Section
         9.7, any Partner having knowledge of a potential Development Option
         may, but shall not be required to, bring the same to the attention of
         the Executive Committee for review. If the Executive Committee
         determines not to undertake any such Development Option, the Partners
         shall mutually agree whether, and on what terms, any such Development
         Option shall be undertaken jointly by the Partners outside the
         Partnership.

                  (ii) Notwithstanding the foregoing, the potential development
         of new base load generation capacity at the Plant (the "Hunlock
         Expansion Project") shall not be a Development Option. In the event
         that the Partners determine to undertake the Hunlock Expansion Project,
         (A) the Partners shall mutually agree on the terms on which the Hunlock
         Expansion Project shall be undertaken and (B) the Partnership shall
         continue to operate the CT under a mutually satisfactory lease between
         the Partnership and the equity owners of the Hunlock Expansion Project.
         UGI GP shall have the right, but not the obligation, to contribute up
         to 50% of the capital required to undertake the Hunlock Expansion
         Project, which capital contribution may be made, at the option of UGI
         GP, in cash, tangible or intangible assets, services, Partnership
         Interests or any combination of the foregoing.

                  (iii) The Executive Committee shall establish the scope of and
         schedule for feasibility studies in connection with the Partners'
         potential interest in the following proposed projects: (A) the Hunlock
         Expansion Project; (B) combustion turbine installation at UGI
         Utilities' LNG facility at Temple, Pennsylvania; (C) wholesale gas and
         electric marketing; (D) contribution to a new venture of UGID's
         interest in the Conemaugh steam electric station; and (E) the joint
         acquisition of Mount Carmel or other non-utility generating stations.

         (b) UGID PUT RIGHTS. For a period of five (5) years from the date
hereof, UGI GP shall have the right, but not the obligation, to require
Allegheny Energy Supply to purchase the Plant (including all inventory of the
Partnership associated with the Plant) or the CT, or both of them, from the
Partnership (collectively, the "UGI Put Right"). The purchase price for the
Plant and such inventory shall be the sum of Fifteen Million Dollars
($15,000,000) plus the value of all inventory of the Partnership associated with
the Plant at the time of such purchase, which amount shall be paid by Allegheny
Energy Supply to the Partnership by wire transfer of immediately available funds
at a closing of such purchase to be held as soon as practicable following
written notice from UGI GP to Allegheny Energy Supply of its determination to
require such purchase. The purchase price for the CT shall be the amount of the

                                      -28-
<PAGE>
book value of the CT on the books of the Partnership as of the date of closing
of such purchase, which amount shall be paid by Allegheny Energy Supply to the
Partnership by wire transfer of immediately available funds at a closing of such
purchase to be held as soon as practicable following written notice from UGI GP
to Allegheny Energy Supply of its determination to require such purchase. In
connection with any such closing, UGI GP and Allegheny Energy Supply shall
jointly prepare, execute and deliver such instruments of transfer that are
reasonably required to effectuate the purchase and sale of the Plant or the CT,
or both of them. All funds received by the Partnership in connection with the
sale of the Plant or the CT, or both of them, shall be paid, as soon as
practicable following the closing of any such sale, to the Partners in a special
distribution in proportion to the Percentage Interests of each as of the date of
distribution. In the event that UGI GP exercises the UGI Put Right with respect
to the Plant and the CT and, upon such exercise, the Partnership's assets
consist solely of intangible items, the Partners thereafter shall cause the
orderly dissolution of the Partnership.

         (c) ALLEGHENY CALL RIGHT. In the event that the Hunlock Expansion
Project is undertaken solely by Allegheny Energy Supply (or an Affiliate
thereof) without the participation of UGI GP or its Affiliates, Allegheny Energy
Supply (or an Affiliate thereof) shall have the right, but not the obligation,
to purchase the Plant (including all inventory of the Partnership associated
with the Plant) from the Partnership. The purchase price for the Plant and such
inventory shall be the sum of Fifteen Million Dollars ($15,000,000) plus the
value of all inventory of the Partnership associated with the Plant at the time
of such purchase, which amount shall be paid by Allegheny Energy Supply (or such
Affiliate) to the Partnership by wire transfer of immediately available funds at
a closing of such purchase to be held as soon as practicable following written
notice from Allegheny Energy Supply (or such Affiliate) to UGI GP of its
determination to undertake such purchase. In connection with any such closing,
UGI GP and Allegheny Energy Supply shall jointly prepare, execute and deliver
such instruments as are reasonably required to effectuate the continued
ownership and operation of the CT by the Partnership, including but not limited
to a ground lease for the CT site. All funds received by the Partnership in
connection with the sale of the Plant shall be paid, as soon as practicable
following the closing of any such sale, to the Partners in a special
distribution in proportion to the Percentage Interests of each as of the date of
distribution.

         (d) UGI RETAINED LIABILITY. Notwithstanding the provisions of Section
9.6(b) (or any other provision) contained in this Agreement to the contrary,
upon the provision of notice by UGI GP to Allegheny GP that UGI GP is exercising
the UGI Put Right (as provided in Section 9.6(b)), UGI GP shall retain and not
be relieved of liability for fifty percent (50%) of any Pre Contribution Loss
actually known to the Partnership as of the date of such notice (the "Notice
Date") in an aggregate amount not to exceed the aggregate amount of the proceeds
of the exercise of

                                      -29-
<PAGE>
the UGI Put Right paid to UGI GP (the "UGI Retained Liability"), and Allegheny
GP shall bear the liability for the remainder of such actually known Pre
Contribution Loss. Notwithstanding the foregoing, UGI GP shall bear no liability
for any Pre Contribution Loss that becomes known to the Partnership subsequent
to the Notice Date. The amount of the fixed portion, if any, of the UGI Retained
Liability as determined as of the closing of the exercise of the UGI Put Right
shall be deducted from the amount payable to UGI GP in connection with such
closing. The remainder of the UGI Retained Liability shall become due and
payable as Pre Contribution Loss in respect thereof becomes fixed. The exclusive
remedies of Allegheny GP and its Affiliates for recovery of any Pre Contribution
Loss, whenever arising, shall be enforcement of (a) UGI GP's covenant in this
Section 9.6(d) in respect of the UGI Retained Liability (b) that certain
Guaranty, dated as of the date hereof, executed and delivered by UGID
guaranteeing the payment of the contingent portion, if any, of the UGI Retained
Liability as determined as of the closing of the exercise of the UGI Put Right.
As used herein, "Pre Contribution Loss" means, collectively, any loss or damage
arising out of a third party claim against the Partnership, its assets and/or
the Partners relating to or resulting from (i) any environmental matter
affecting the Plant and/or Site that existed prior to the date of formation of
the Partnership, (ii) any material breach of any representation or warranty of
UGID provided in the Formation Agreement (determined as though such
representations and warranties survived, until the Notice Date but not
thereafter, the formation of the Partnership) and (iii) the failure of the Plant
and/or the Site to comply as of any date prior to the formation of the
Partnership in all material respects with all laws, regulations, rules,
ordinances, orders, permits and notices of any governmental entity or agency
thereof applicable to the Plant and/or Site.

SECTION 9.7 COMPETITIVE ACTIVITIES.

         (a) Subject to the exceptions set forth in the introductory clause of
the sentence immediately following, notwithstanding any provision to the
contrary contained herein, and notwithstanding any common law or statutory

         (i)      Affiliates and Related Parties of each Partner shall have the
                  right to engage in any Business Opportunity that presents
                  itself, and any such activities shall in no way or manner

                  Partner to the Partnership or the other Partners;

         (ii)     No Partner (nor any Affiliate or Related Party of such

                  Partnership (or any Affiliates or Related Parties of the
                  Partnership or any Partners) and (B) any obligation to offer

            Notwithstanding any provision to the contrary contained in this
Agreement, including but not limited to the provisions of Section 9.1, Section
9.2 and Section 9.3, all Partners shall at all times maintain and adhere to
provisions in such Partners' charters or governance documents that provides, in

Partners will not engage in any activities, shall not incur any indebtedness (or
guaranty indebtedness of others), shall not commingle funds or accounts and
shall not consolidate for any purpose with any other entity, except as otherwise
expressly authorized by the Partnership. The Partners and any successor or
assign of any Partner, shall submit such governance provisions to the
Partnership for review and approval prior to affecting any Transfer of any
Partnership Interest. The Partners intend that each Partner be a so-called
"special purpose entity" engaged only in the activity of being a Partner in the

manner consistent with such intention.

                         ARTICLE 11 - BOOKS AND RECORDS

SECTION 11.1 BOOKS AND RECORDS.

office records, books and accounts (which records, books and accounts shall be
and remain the property of the Partnership) in which shall be entered fully and
accurately each and every transaction with respect to the Partnership Assets.
Bills, receipts and vouchers shall be maintained on file by the Administrative
Partner. The Administrative Partner shall maintain said books and accounts in a
safe manner and separate from any records not related directly to the
Partnership or the Partnership Assets. The Administrative Partner shall cause
audits to be performed and audited statements and income tax returns to be
prepared as required by Section 11.3. Such books and records of account shall be
prepared and maintained by the Administrative Partner at the principal place of
business of the Partnership or such other place or

                                      -31-
<PAGE>
places as may be determined by the Executive Committee from time to time. Each
Partner or its duly authorized representative (including, without limitation,
its accountants, attorneys or other designees) shall have the right to inspect,
examine and copy such books and records of account at the Partnership's office
during reasonable business hours. A reasonable charge for copying books and
records may be charged by the Partnership.

SECTION 11.2 ACCOUNTING AND FISCAL YEAR.

            The books of the Partnership shall be maintained in accordance with
GAAP and any other applicable requirements and the Partnership shall report its

changed from time to time at the election of the Partners in accordance with the
Code and applicable Regulations.

SECTION 11.3 FINANCIAL STATEMENTS AND REPORTS.

         (a) The Administrative Partner shall prepare, at Partnership expense

(which financial statements shall be prepared in accordance with GAAP
consistently applied) and other information that the Executive Committee
determines appropriate. In addition, within forty-five (45) days after the end
of each Fiscal Year, the Administrative Partner will prepare, at Partnership
expense, and deliver to each Partner a report setting forth in sufficient detail
all such information and data with respect to business transactions effected by
or involving the Partnership during the Fiscal Year as will enable the
Partnership and each Partner timely to prepare its federal, state and local
income tax returns in accordance with all applicable laws, rules and
regulations. The Administrative Partner also will prepare federal, state and
local tax returns required of the Partnership, submit those returns to the
Executive Committee for its approval no later than thirty (30) calendar days
prior to the date required for the filing thereof (including any extensions
granted) and will file the tax returns after they have been approved by the
Executive Committee. In the event the Executive Committee shall not desire or be
able to approve any such tax return prior to the date required for the filing
thereof (including any extensions granted), the Administrative Partner will
timely obtain an extension of such date.

         (b) All decisions as to accounting principles shall be made by the
Executive Committee, subject to the provisions of this Agreement.

SECTION 11.4 ACCOUNTANT.

         The Partnership shall retain an independent U.S. public accounting firm
of national stature, as selected by the Executive Committee, as the accountants
and auditors for the Partnership (the "Accountant"). The Accountant shall audit

Committee shall direct. The fees and expenses of the Accountant shall be an
expense of the Partnership.

         (a) The Executive Committee shall designate a Partner to attend to or
cause to be attended to all of the tax affairs of the Partnership, who, as such,
will serve as the "Tax Matters Partner" of the Partnership. Notwithstanding the
foregoing, each Partner shall otherwise be considered to have retained such
rights (and obligations, if any) as are provided for under the Code with respect
to any examination, proposed adjustment or proceeding relating to Partnership
items. UGI GP shall be the initial Tax Matters Partner. The Administrative
Partner will give prompt notice to all Partners of any audit or other proceeding
involving income tax liability of the Partnership of which the Administrative
Partner is notified or becomes aware. The Administrative Partner shall endeavor
at all times to cause the Partnership to be classified as a partnership for
federal income tax purposes.

         (b) The Partnership will reimburse the Tax Matters Partner for all
expenses reasonably incurred by it in connection with the fulfillment of its
duties set forth in subparagraph (a) hereof including, without limitation, the
preparation of tax information, returns, and any administrative or judicial
proceeding with respect to the tax liabilities of the Partners.

SECTION 11.7 TAX ELECTIONS AND TREATMENT.

         All elections required or permitted to be made by the Partnership under
the Code shall be made or not made by the Tax Matters Partner, with the advice
of the Accountant and tax counsel for the Partnership, in any manner that
reasonably reflects the purpose and intention of this Agreement.

Budget and the Initial Operating Plan and any future Budget and Operating Plan
shall each be in the form specified from time to time by the Executive
Committee.

         (b) The Executive Committee shall review the then current Budget and
Operating Plan at or around the sixth month following the starting date for the
Budget and the Operating Plan and shall make such amendments thereto as it shall
determine to be in the best interests of the Partnership.

         (c) On the Effective Date, the Executive Committee shall cause the

in connection therewith. Receipt by any party of any money or other
consideration due under this Agreement shall not constitute a waiver of any
provision of this Agreement.

         (b) Notwithstanding anything to the contrary contained in this

RE.: OFFER (A)

Dear Sirs,

we, FLAGA GmbH, An der Bundesstrasse 6, 2100 Leobendorf, Austria, herewith refer
to our previous Offer (A) (hereinafter the "Offer (A)") and propose to amend the
terms of Offer (A) as follows (Clauses referred to herein are Clauses of Offer

Clause 2.2. shall be replaced by the following:

"2.2. The Borrower shall draw the Loan either in EURO or in Austrian Schilling
("ATS") by giving the Bank notice in the form of Annex I hereto not later than
11:00 a.m. central European time ("CET") on the Business Day on which the Loan
amount is required to be disbursed. As at the end of each interest period and
before 31. December 2001, the Borrower shall have the right to convert a part of
the Loan amount drawn hereunder equivalent to EUR 18.500.000 into USD. This
right, however, can only be exercised once."

In Clause 4.2. the following provision shall be added:

"In the event that the Borrower exercises its conversion right stipulated in
Clause 2.2., the following shall apply to the respective USD amount:

The rate of interest payable on the outstanding Loan amount in USD for each
interest period shall be the rate per annum representing the aggregate of:

(a)      the margin of 1.25% and

(b)      the rate

         (i)      which is quoted for 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-,
                  11- or 12-month deposits in USD (depending on

Offer (A)                                                                 page 1

                  or if no such rate is then available for USD deposits of 1-,
                  2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-, 11- or 12-month, the rate
                  which is determined by the Bank to be the arithmetic mean
                  (rounded up to four decimal places) of the offered rates per
                  annum for 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-, 11- or
                  12-month deposits which are advised to the Bank by three major
                  banks active in the London inter-bank market selected by the
                  Bank, or

         (ii)     which is quoted by the Bank for interest periods starting at
                  the date of the exercise of the conversation right stipulated
                  in Clause 2.2. ("Conversion Date") until the following
