Statement") detailing the actual capital contributions, if any, made by the

to the amounts disputed. The fees and disbursements of the Independent

statement made by the Seller to the Purchaser contains any untrue statement of a
material fact, or omits or will omit to state any material fact necessary, in
light of the circumstances under which it was made, in order to make the
statements herein or therein not misleading.

time have held the office of the Chief Executive Officer, President, Chief
Financial Officer or any Vice President or equivalent position of the Seller and
the terms "knowledge" and "known" mean the actual conscious awareness of any
such person.

the Seller and its Parents shall, without any further responsibility or
liability of, or recourse to the Purchaser, absolutely and irrevocably be joint
and severally liable and responsible for (i) the respective Tax liabilities of
the Seller and its Parents (including Tax liabilities attributable to ownership
of the Tuscarora Partnership Interest prior to the Closing Time), including any
such income Tax liabilities of the Seller and its Parents that may result from
the consummation of the transactions contemplated by this Agreement, and (ii)
any and all claims, liabilities and obligations of the Seller and its Parents
(whether accruing or arising before, on or after the Closing Time) which
primarily arise out of or relate to any property, operations or business of the
Seller or its Parents other than with respect to the Tuscarora Partnership
Interest (the items in (i) and (ii), collectively the "EXCLUDED LIABILITIES").
The Purchaser shall not be liable to the Seller and its Parents or any third
parties for any reason whatsoever on account of any of the Excluded Liabilities.

     The Seller and its Parents shall indemnify, defend, save and hold harmless
the Purchaser from and against all claims, liabilities, obligations, losses,
costs, costs of defense (as and when incurred), including expenses, fines,
charges, penalties, allegations, demands, damages (including but not limited to
actual, punitive or consequential, foreseen or unforeseen, known or unknown),
settlements, awards or judgments of any kind or nature whatsoever and reasonable
outside attorneys' and consultants' fees, to the extent arising out of (a) the
Excluded Liabilities, or (b) any inaccuracy, violation or the breach by the
Seller or its Parents of any representation, warranty, condition or covenant
under this Agreement, all of which are hereinafter collectively referred to as
the "PURCHASER DAMAGES".

     Notwithstanding anything else contained in this Section 9, the aggregate
liability of the Seller and its Parents hereunder under clause (b) above will be
limited to the Purchase Price.

     Purchaser Damages with respect to which, but only to the extent that, any
proceeds are received by, or on behalf of, the Purchaser or any of its Parents,
from any third party insurance policy (and are non-reimbursable by the Purchaser
or any of its Parents), shall not be the subject of indemnification under this
Agreement.

     9.2  EXCULPATION AND INDEMNIFICATION BY THE PURCHASER. Subject to SECTION
9.3, the Purchaser shall, without any further responsibility or liability of, or
recourse to, any of the Seller and its Parents, absolutely and irrevocably
assume and be solely liable and responsible for any and all claims, liabilities
and obligations (whether accruing or arising before, on or after the Closing
Time) which primarily arise out of or relate to the Tuscarora Partnership
Interest (including pursuant to the Tuscarora Partnership Agreement and other
partnership documents and the business conducted by Tuscarora, other than
claims, liabilities and obligations as to which the Purchaser would be entitled
to indemnification under Section 9.1 of this Agreement (the "ASSUMED
LIABILITIES"). Except as set forth in the immediately preceding sentence, none
of the Seller and its Parents shall be liable to the Purchaser or any third
parties for any reason whatsoever on account of any of the Assumed Liabilities.


                                       11
<PAGE>

     The Purchaser shall indemnify, defend, save and hold harmless the Seller
and its Parents from and against all claims, liabilities, obligations, losses,
costs, costs of defense (as and when incurred), including expenses, fines,
charges, penalties, allegations, demands, damages (including but not limited to
actual, punitive, or consequential, foreseen or unforeseen, known or unknown),
settlements, awards or judgments of any kind or nature whatsoever and reasonable
outside attorney's and consultants' fees, to the extent arising out of (a) the
Assumed Liabilities or (b) any inaccuracy, violation or the breach by the
Purchaser of any representation, warranty, condition or covenant under this
Agreement, all of which are hereinafter collectively referred to as the "SELLER
DAMAGES".

     Seller Damages with respect to which, but only to the extent that, any
proceeds are received by, or on behalf of, the Seller, or by any of its Parents,
from any third party insurance policy (and are non-reimbursable by the Seller or
any of its Parents), shall not be the subject of indemnification under this
Agreement.

     9.3  SPECIFIC INDEMNIFICATION ISSUES. (a) In the event a claim, demand,
action or proceeding is brought by a third party in which the liability as
between the Seller and its Parents, on the one hand, and the Purchaser, on the
other hand, is determined after trial in any judgment, award or decree to be
joint or concurrent or in which the entitlement to indemnification hereunder is
not readily determinable, the Parties shall negotiate in good faith in an effort
to agree, as between the Seller and its Parents, on the one hand, and the
Purchaser, on the other hand, on the proper allocation of liability or
entitlement to indemnification, as well as the proper allocation of the costs of
any joint defense or settlement pursuant to SECTION 9.5(d) of this Agreement,
all in accordance with the provisions of, and the principles set forth in, this
Agreement. In the absence of any such agreement, such allocation of liability,
entitlement to indemnification and allocation of costs shall be subject to
ultimate resolution between the Seller and its Parents, on the one hand, and the
Purchaser, on the other hand, pursuant to SECTION 10 of this Agreement.

         (b)  It is acknowledged that after the Closing Time, the parties may
have various business relationships, which relationships will be described in
contracts, agreements and other documents entered into by the relevant parties.
Such documents may include agreements by the parties and their Parents to
supply, after the Closing Time, credit or services. Such business relationships
shall not be subject to the indemnity provisions hereof, unless the parties
expressly agree to the contrary in the agreements governing such relationships.

     9.4  NOTICE AND PAYMENT OF CLAIMS. (a) If any person entitled to a defense
and/or indemnification under this Agreement (the "INDEMNIFIED PARTY") determines
that it is or may be entitled to a defense or indemnification by the Purchaser
or any of the Seller or its Parents, as the case may be (the "INDEMNIFYING
Party"), under this Agreement:

          (i) The Indemnified Party shall deliver promptly to the Indemnifying
     Party a written notice and demand for a defense or indemnification,
     specifying the basis for the claim for defense and/or indemnification, the
     nature of the claim, and if known, the amount for which the Indemnified
     Party reasonably believes it is entitled to be indemnified. Nothing in this
     subparagraph shall be interpreted to invalidate any claim by the
     Indemnified Party to be entitled to indemnification,



                                       12
<PAGE>

     except to the extent the failure of the Indemnified Party to deliver such
     notice resulted in actual prejudice.

          (ii) The Indemnifying Party shall have 30 days from receipt of the
     notice requesting indemnification within which to either: (A) assume the
     defense of such litigation or claim; (B) pay the claim in immediately
     available funds; (C) reserve its rights pending resolution under SECTION
     9.5(d); or (D) object in accordance with CLAUSE (b) of this SECTION 9.4.
     This 30-day period may be extended by agreement of the Parties. Nothing in
     this subparagraph shall be interpreted to abrogate or delay a Party's
     obligation to provide the other with a defense under this Agreement.

          (b)  The Indemnifying Party may object to the claim for defense
and/or indemnification set forth in any notice; PROVIDED, HOWEVER, that if the
Indemnifying Party does not give the Indemnified Party written notice setting
forth its objection to such claim (or the amount thereof) and the grounds
therefor within the same 30-day period (or any extended period), the
Indemnifying Party shall be deemed to have acknowledged its liability to provide
a defense or to pay the amount of such claim and, subject to SECTION 10 of this
Agreement, the Indemnified Party may exercise any and all of its rights under
applicable law to collect such amount or obtain such defense. Any objection to a
claim for a defense or indemnification shall be resolved in accordance with
SECTION 10 of this Agreement.

          (c)  To the extent provided in the last sentence of SECTION 9.1 of
this Agreement or the last sentence of SECTION 9.2 of this Agreement, the right
to a defense or indemnification under this Agreement applies only insofar as
defense and indemnification are not provided for by insurance (whether through a
third party or otherwise). Nevertheless, the potential availability of insurance
coverage to the Seller, its Parents, or the Purchaser shall not relieve the
other party of its obligations for defense or indemnification hereunder, or
delay either party's obligations to the other to assume a defense or pay any
sums due hereunder.

          (d)  Payments due to be made to any Indemnified Party under this
SECTION 9 shall bear interest from the date on which the Indemnified Party paid
any amount or actually suffered a loss in respect of Purchaser Damages or Seller
Damages, as the case may be, to but excluding the date of actual payment
(whether before or after judgment) at the prime rate announced by Chase Bank for
its corporate customers during such period.

          (e)  Payments due to be made under this Agreement shall be free
and clear of all deductions, withholdings, set-offs or counterclaims whatsoever,
except as may be required by law.

     9.5  DEFENSE OF THIRD PARTY CLAIMS. (a) If the Indemnified Party's claim
for indemnification is based, under this Agreement, on a claim, demand,
investigation, action or proceeding, judicial or otherwise, brought by a third
party, and the Indemnifying Party does not object under SECTION 9.4(b) of this
Agreement, the Indemnifying Party shall, within the 30 day period (or any
extended period) referred to in SECTION 9.4(a) of this



                                       13
<PAGE>

Agreement, assume the defense of such third-party claim at its sole cost and
expense and shall thereafter be designated as the "CASE HANDLER." Any such
defense shall be conducted by attorneys employed by the Indemnifying Party. The
Indemnified Party may retain attorneys of its own choosing to participate in
such defense at the Indemnified Party's sole cost and expense.

          (b)  If the Indemnifying Party assumes the defense of any such
third-party claim, the Indemnifying Party may settle or compromise the claim
without the prior consent of the Indemnified Party so long as all present and
future claims relating to the compromised claim against the Indemnified Party
are irrevocably and unconditionally released in full.

          (c)  The Indemnifying Party shall pay to the Indemnified Party in
immediately available funds the amount for which the Indemnified Party is
entitled to be indemnified within 30 days after the settlement or compromise of
such third-party claim or the judgment of a court of competent jurisdiction (or
within such longer period as agreed to by the parties). If the Indemnifying
Party does not assume the defense of any such third-party claim, the
Indemnifying Party shall be bound by the result obtained with respect thereto by
the Indemnified Party, except that the Indemnifying Party has the right to
contest that it is obligated to the Indemnified Party under the terms of this
Agreement, provided the Indemnifying Party shall have raised its objection in a
timely manner under SECTION 9.4 of this Agreement.

          (d)  In the event a claim, demand, action or proceeding is brought
by a third party in which the liability as between the Purchaser and the Seller
and its Parents is alleged to be joint or in which the entitlement to
indemnification hereunder is not readily determinable, the Parties shall
cooperate in a joint defense. Such joint defense shall be under the general
management and supervision of the party which is expected to bear the greater
share of the liability, and which will be considered the Case Handler, unless
otherwise agreed; PROVIDED, HOWEVER, that neither Party shall settle or
compromise any such joint defense matter without the consent of the other. The
costs of such joint defense, any settlement and any award or judgment (unless
the award or judgment specifies otherwise) shall be borne as the Parties may
agree; or in the absence of such agreement, such costs shall be borne by the
Party incurring such costs, subject to ultimate resolution between the Purchaser
and the Seller pursuant to SECTION 10 of this Agreement.

     9.6  COOPERATION AND PRESERVATION OF RECORDS. (a) The Purchaser and the
Seller and its Parents shall cooperate with one another fully and in a timely
manner in connection with the defense of any litigation and claims pending as of
the Closing Time or brought, threatened or alleged after the Closing Time,
against the Purchaser and/or the Seller and its Parents, as such claims or
litigation relate to the Tuscarora Partnership Interest in Tuscarora.

          (b)  Such cooperation shall include, without limitation, making
available to the other Party, during normal business hours and upon reasonable
notice, all books, records and information ("LITIGATION RECORDS"), officers and
employees (without substantial interruption of employment) necessary or useful
in connection with any actual or threatened claim, audit, action or proceeding.


                                       14
<PAGE>

          (c)  Each Party shall maintain the Litigation Records, or at the
request of the other party, shall issue, notices exempting from destruction any
Litigation Records which the requesting Party represents may be necessary to the
defense of, or required to be produced in discovery in connection with, any such
claim, investigation, audit, action or proceeding and shall refrain from
destroying any such Litigation Records until authorized by the requesting Party.
The requesting Party shall notify the other Party promptly when the Litigation
Records are no longer required to be maintained.

          (d)  The Party requesting access to Litigation Records or officers
and employees pursuant to CLAUSE (b) hereof or preservation of Litigation
Records pursuant to CLAUSE (c) hereof shall bear all reasonable out-of-pocket
expenses (except reimbursement of salaries, employee benefits and general
overhead) incurred by the other Party in connection with providing such
Litigation Records or officers and employees.

          (e)  The Party providing Litigation Records hereunder may elect,
upon a reasonable basis and within a reasonable time, to designate all or a
portion of the Litigation Records as confidential or proprietary. If Litigation
Records are so designated, the Party receiving them will treat them as it would
its own confidential or proprietary information and will take all reasonable
steps to protect and safeguard the Litigation Records while in its own custody
and will attempt to shield such information from disclosure by motions to quash,
motions for a protective order, redaction or other appropriate actions.

     9.7  GUARANTEE OF PERFORMANCE. In addition to the indemnification
obligations of Parents set forth in this SECTION 9, Parents hereby, jointly and
severally, absolutely and unconditionally guarantee to the Purchaser the
performance by the Seller of all of its agreements and obligations under this
Agreement, subject to any limitations on the Seller set forth in this Agreement,
subject to the limitations on the liability of the Seller and its Parents
contained in the third paragraph of Section 9.1.

10.  ARBITRATION.

     10.1 Resolution of any and all disputes arising from or in connection with
this Agreement, whether based on contract, tort, statute or otherwise, including
but not limited to, disputes over arbitrability and disputes in connection with
claims by third parties (collectively, "DISPUTES"), shall be exclusively
governed by and settled in accordance with the provisions of this SECTION 10;
PROVIDED, HOWEVER, that nothing contained herein shall preclude any party from
seeking or obtaining (a) injunctive relief or (b) equitable or other judicial
relief, in each case to preserve the status quo, pending resolution of Disputes
hereunder. Any Party may commence proceedings hereunder by delivering a written
notice to any other Party providing reasonable description of the Dispute to the
other, and expressly requesting arbitration hereunder. The Parties hereby agree
to submit all Disputes to arbitration under the terms hereof, which arbitration
shall be final, conclusive and binding upon the parties, their successors and
assigns. The arbitration shall be conducted in Calgary, Alberta, by a single
arbitrator (the "ARBITRATOR") selected by agreement of the parties not later
than ten (10) days after delivery of the Demand or, failing such agreement,
appointed pursuant to the commercial arbitration rules of the American
Arbitration Association, as amended from time to time (the "AAA



                                       15
<PAGE>

RULES"). If the arbitrator so selected becomes unable to serve, his or her
successor shall be similarly selected or appointed. The arbitration shall be
conducted pursuant to the Federal Arbitration Act and such procedures as the
parties involved in any Dispute may agree, or, in the absence of or failing such
agreement, pursuant to the AAA Rules. Notwithstanding the foregoing: (i) each
Party shall have the right to audit the books and records of each other party
that are reasonably related to the Dispute; (ii) each Party shall provide to
each other Party involved in the applicable Dispute, reasonably in advance of
any hearing, copies of all documents which such Party intends to present in such
hearing; and (iii) each Party shall be allowed to conduct reasonable discovery
through written requests for information, document requests, requests for
stipulation of fact and depositions, the nature and extent of which discovery
shall be determined by the Arbitrator, taking into account the needs of the
parties and the desirability of making discovery expeditious and cost effective.
All hearings shall be conducted on an expedited schedule, and all proceedings
shall be confidential. Any Party may, at its expense, make a stenographic record
thereof. The Arbitrator shall complete all hearings not later than 90 days after
its selection or appointment, and shall make a final award not later than 30
days thereafter. The award shall be in writing and shall specify the factual and
legal basis for the award. The Arbitrator shall apportion all costs and expenses
of arbitration, including the Arbitrator's fees and expenses and fees and
expenses of experts, between the prevailing and non-prevailing Party as the
Arbitrator deems fair and reasonable. Notwithstanding the foregoing, in no event
may the Arbitrator award multiple, punitive or exemplary damages. Any
arbitration award shall be binding and enforceable against each Party involved
in the particular Dispute and judgment may be entered thereon in any court of
competent jurisdiction.

11.  ADDITIONAL AGREEMENTS

     11.1 The Seller agrees to cooperate with the Purchaser in causing Tuscarora
to obtain the consent of the holders of Series A Notes issued under the
Indenture, Assignment and Security Agreement of Tuscarora to Wilmington Trust
dated December 21, 1995 such that any future acquisition of an additional
general partner interest in Tuscarora by Purchaser does not result in a
requirement for prepayment of the Series A Notes under the terms of such
indenture; provided that the terms of obtaining such consents are commercially
reasonable and acceptable to Tuscarora and all costs associated therewith are
borne solely by the Purchaser.
