          ------------------------- 


     (a)  Subject to the provisions of this Section 1.5, Seller shall convey to
     Buyer, and Buyer shall accept from Seller, the Related Property subject to,
     and only subject to:  (i) all easements, covenants, conditions,
     restrictions, exceptions, reservations and encumbrances (other than liens,

     such facts as would be revealed by an inspection of the Related Property
     (the items described in clauses (i) through (vii) above collectively
     referred to herein as "Title Exceptions").


     (b)  Buyer shall be entitled to obtain prior to the Closing, at Buyer's
     option and sole cost, metes and bounds surveys made by a registered
     surveyor setting forth the location of all

                                       8

     ascertainable easements and rights-of-way.  Seller agrees to cooperate with
     Buyer's efforts to obtain the surveys, including furnishing Buyer promptly
     upon request copies of all surveys which Seller may have in its possession.

 
     (c)  Buyer shall be entitled to obtain prior to the date of the Closing, at

     1.6  Restrictions on Transfer of Permits, Licenses, Leases and Contracts.
          ------------------------------------------------------------------- 

     (a)  To the extent that any lease, contract, license, permit, approval,
     consent, or other agreement or commitment (but not including such which are
     Related Property) included as an Asset to be transferred to Buyer is by its
     express or implied terms or by operation of law not capable of being
     validly assigned or transferred without the consent or waiver of the issuer
     thereof or the other party thereto, or any third person (including a
     government or governmental unit), or if such assignment, transfer or
     attempted assignment or transfer would constitute a termination or breach
     thereof or a violation of any law, decree, order, regulation or other
     governmental edict or is otherwise not practicable, this Agreement shall
     not constitute an assignment or transfer thereof, or an attempted
     assignment or transfer thereof.  Any such lease, contract, license, permit,
     approval, consent, agreement or commitment (but not including such which
     are Related Property) identified by Buyer in writing prior to the Closing
     is referred to herein as a "Restricted Asset".

     (b)  Seller shall be under no obligation to transfer, or attempt to obtain
     necessary consents and waivers, with respect to any Restricted Asset which
     is a Permit that is not capable of being assigned.  Seller is not obligated
     to transfer to Buyer any other

                                       10

 
     Restricted Asset (an "Other Restricted Asset") without Seller and Buyer
     first having obtained all necessary consents and waivers.  Seller shall use
     reasonable efforts for a twelve (12) month period, commencing on the date
     hereof, and Buyer shall cooperate with Seller, to obtain the consents and
     waivers necessary for Seller to convey to Buyer any such Other Restricted
     Asset as soon as practicable; provided, however, that neither party shall
     be obligated to pay any consideration therefor to the party from whom the
     consent or waiver is requested.

     (c)  To the extent that the consents and waivers for Other Restricted
     Assets referred to in Section 1.6(b) hereof are not obtained by Seller, or
     until the impracticalities of transfer referred to therein are resolved,
     Seller shall, during the twelve (12) month period commencing on the date
     hereof or such longer period as Seller may desire (but, as to any
     particular Other Restricted Asset, not longer than the term thereof,
     including renewal options), use its reasonable efforts to (i) provide to
     Buyer at Buyer's request the benefits of any Other Restricted Asset, but
     only to the extent necessary to permit Buyer's ownership or use of the
     Assets to the same or similar extent as owned or used by Seller in the six
     (6) months immediately prior to the Closing, and (ii) cooperate in any
     reasonable and lawful arrangement designed to provide such benefits to
     Buyer.  After Seller has fulfilled Seller's obligations set forth in
     Section 1.6(b) hereof, Seller shall have no further obligations hereunder
     with respect to assignment of such Other Restricted Asset, and the failure
     to obtain any necessary consent or waiver with respect thereto shall not be
     a breach of this Agreement.  In no event shall Seller's obligations under
     this

                                       11

 
     Section 1.6 include any obligation to commence or prosecute litigation
     against any third party.  Buyer agrees to reimburse promptly Seller for its
     reasonable costs incurred in connection with this Section 1.6(c).

     (d)  To the extent that Buyer is provided the benefits pursuant to Section
     1.6(c) hereof of any Other Restricted Asset, Buyer shall perform, for the
     benefit of the issuer thereof or the other party or parties thereto, the
     obligations of Seller thereunder or in connection therewith, but only to
     the extent that (i) such action by Buyer would not result in any default
     thereunder or in connection therewith, and (ii) such obligation would have
     been assumed by Buyer pursuant to Article III hereof or pursuant to the
     contract assignment and assumption agreement to be executed by the parties
     pursuant to Section 1.4(d) and Article XI hereof, but for the
     nonassignability or nontransferability thereof.  If Buyer shall fail to
     perform to the extent required herein, Seller shall cease to be obligated
     under this Section 1.6 in respect of the instrument which is the subject of
     such failure to perform unless and until such situation is remedied, and
     Buyer shall indemnify, defend and hold Seller harmless from the
     consequences of Buyer's failure to perform in accordance with the
     provisions of Section 12.2 of this Agreement.

     1.7  Destruction of the Assets.
          ------------------------- 

     (a)  In the event any of the Assets material to the operation of the
     Pipeline System are damaged or destroyed by fire or other casualty, or are
     condemned or threatened to be

                                       12

 
     condemned, after the date hereof and prior to the Closing, Seller shall
     promptly notify Buyer in writing of such, including reasonable detail
     regarding the facts related thereto known to Seller.

     (b)  If in Seller's good faith judgment repair or replacement of such
     Assets can be made at a cost not to exceed $1,355,000, then Seller, at
     Seller's sole cost, shall promptly commence and diligently pursue the
     repair or replacement of such Assets to Buyer's reasonable satisfaction and
     return of the Pipeline System to its normal operating condition as operated
     in the six (6) months preceding the date hereof.  If in Seller's good faith
     judgment the cost of such replacement or repair of such Assets may exceed
     $1,355,000, then Seller shall elect to:  (i) terminate this Agreement, or
     (ii) subject to any rights of Buyer in Section 1.7(c), become obligated to
     Buyer, at Seller's sole cost, promptly to commence and diligently pursue
     the repair or replacement of such Assets to Buyer's reasonable satisfaction
     and return of the Pipeline System to its normal operating condition as
     operated in the six (6) months preceding the date hereof.  Seller shall
     notify Buyer of Seller's repair and replacement cost estimate and, if
     applicable, its election under the preceding sentence within ten (10) days
     of such loss, destruction, condemnation or threat of condemnation, which
     notice shall include reasonable detail supporting such cost estimate.

     (c)  In the event any of the Assets material to the operation of the
     Pipeline System are damaged or destroyed by fire or other casualty, or are
     condemned or threatened to be

                                       13

 
     condemned, after the date hereof and prior to the Closing and in Buyer's
     good faith judgment the repair or replacement of such Assets and return of
     the Pipeline System to its normal operating condition as operated in the
     six (6) months preceding the date hereof may (i) exceed $4,065,000 in cost,
     or (ii) take longer than ninety (90) days, then Buyer may elect to
     terminate this Agreement by sending written notice of such election to
     Seller within ten (10) days of Seller's notice under Section 1.7(b).

     (d)  If such loss, destruction, condemnation or threat of condemnation
     occurs within the ten (10) day period prior to the Closing, the Closing
     shall be delayed to the date ten (10) days after the giving of Seller's
     notice under Section 1.7(b), to enable the applicable elections to be made,
     or if such tenth (10th) day is a Saturday, Sunday or legal holiday in which
     banks in Chicago, Illinois are not open for business, the Closing shall be
     delayed to the first business day after such tenth (10th) day.  If (i) any
     damage, destruction, condemnation or threat of condemnation of any of the
     Assets occurs after the date hereof and prior to the Closing, (ii) Seller
     is obligated or elects to repair or replace such Assets pursuant to this
     Section 1.7, (iii) Buyer does not exercise any right of termination of this
     Agreement pursuant to this Section 1.7, and (iv) the repair or replacement
     has not been completed prior to the scheduled time and date for the
     Closing, then Buyer may, at its option, elect to either (1) delay the
     Closing until the fifth (5th) business day after all the repairs and
     replacements have been completed to Buyer's reasonable satisfaction and the
     Pipeline System has been returned to its normal operating condition as
     operated in the six (6) months preceding the date hereof, or (2) close the

                                       14

 
     transactions contemplated by this Agreement on the scheduled date for the
     Closing and require Seller to complete the repairs and replacements
     contemplated by this Section 1.7 after the Closing.

          --------------                                                        
Closing and the other undertakings of Seller hereunder, Buyer shall pay to
Seller at the Closing twenty seven million, one hundred thousand dollars
($27,100,000.00) (the "Purchase Price").
 
     2.2  Payment.  At the Closing, Buyer shall deposit the Purchase Price in
          -------                                                            
immediately available funds by bank wire transfer in an account or accounts (but
not more than two (2) accounts) at a national bank or banks located in the
United States designated by Seller.  Seller shall give notice to Buyer of the
account or accounts and any other wire transfer instructions at least three (3)
days before the day of the Closing.

     2.3  Prorations.
          ---------- 

     (a)  The following items relating to the Assets shall be prorated at the
     Closing between Buyer and Seller and final payment made to the party to
     whom it is due based on the respective period in which the parties own the
     Assets during the calendar year which includes the Closing (the
     "Prorations"):

                                       15

 
     (i)   all real estate, personal property and other ad valorem taxes and
assessments (excluding penalties and interest) assessed or levied against the
Related Property;

     (ii)  charges, if any, for utilities servicing the Pipeline System and
the Related Property;

     (iii) payments, if any, under service and similar Contracts that are
assumed by Buyer;

     (iv)  prepaid rent, prepaid property taxes, prepaid supplies, advances
and other prepaid costs and deposits related to the Pipeline System, the Related
Property, the Permits or the Contracts; and

     (v)   all other charges and fees related to the Assets customarily
prorated and adjusted in similar transactions.

For purposes of making such prorations, Seller shall be deemed to have conveyed
the Assets as of 11:59 p.m. the day before the Closing. In the event that
accurate prorations and other adjustments cannot be made because current bills
are not obtainable at the Closing, the parties shall prorate on the best
available information, subject to the Post-Closing Adjustment set forth in
Section 2.4 below.

                                       16

 
     (b)  At the Closing, Seller shall pay Buyer four hundred eighty thousand,
     six hundred eighty five dollars and twenty cents ($480,685.20) as a good
     faith estimate by the parties of the amount to be reimbursed to Buyer for
     the Prorations, subject to the Post-Closing Adjustment set forth in Section
     2.4 below.  At the Closing, Seller shall deposit the aforementioned amount
     in immediately available funds by bank wire transfer in an account at a
     national bank located in the United States designated by Buyer.  Buyer
     shall give notice to Seller of the account and any other wire transfer
     instructions at least three (3) days before the day of the Closing.

     2.4  Post-Closing Adjustment.
          ----------------------- 

     (a)  Buyer will provide to Seller copies of any invoices paid by Buyer
     after the Closing that relate to Prorations.  Within one hundred and twenty
     (120) days after the Closing, Seller shall provide Buyer with a statement
     of prorations based on final invoices or other final amounts setting forth
     the prorations required by Section 2.3, certified by an officer of Seller
     ("Statement of Prorations").  Seller shall also provide any supporting
     documentation reasonably requested by Buyer.  If the Statement of
     Prorations indicates that Buyer paid an excess amount at the Closing with
     respect to the Prorations required by Section 2.3, the Statement of
     Prorations shall be accompanied by a check in payment of the excess to
     Buyer, plus interest from the later of (i) the date of the Closing or (ii)
     the date of payment of the expense that is subject to proration, through
     the date of payment of such excess to Buyer, calculated at an interest rate
     equal to the most recently

                                       17

 
     quoted (at the time of payment of such excess to Buyer) one month LIBOR
     rate, compounded annually until paid.

     (b)  Within thirty (30) days of receipt of the Statement of Prorations and
     any supporting documentation reasonably requested by Buyer, final payment
     shall be made to the party to whom it is due for the difference between (i)
     the good faith estimate of the Prorations paid at the Closing pursuant to
     Section 2.1 herein, and (ii) the corresponding amounts reflected in the
     Statement of Prorations, plus interest from the later of (i) the date of
     the Closing or (ii) the date of payment of the expense that is subject to
     proration, through the date of payment of such difference, calculated at an
     interest rate equal to the most recently quoted (at the time of payment of
     such difference) one month LIBOR rate, compounded annually until paid.

     (c)  Buyer shall have the right to conduct an audit of the relevant books
     and records of Seller for the purpose of determining the accuracy of the
     Statement of Prorations, provided that any audit must be completed and
     written notice of contest of the Statement of Prorations must be given
     within three (3) months after receipt of the Statement of Prorations by
     Buyer or the Statement of Prorations as delivered by Seller shall be deemed
     to be conclusive and binding on the parties.  If as the result of any such
     audit Buyer contests any portion of the Statement of Prorations within such
     three (3) month period, Buyer and Seller shall cooperate in good faith to
     reach agreement on a final Statement of Prorations.  If Buyer and Seller
     cannot agree within thirty (30) days of the date of the

                                       18

 
     written notice of contest, the parties will submit the issue to binding
     arbitration by a single arbitrator under the then-existing commercial
     arbitration rules of the American Arbitration Association.

     2.5  Like-Kind Exchange.
          ------------------ 

     (a)  It is Seller's intention to exchange the Assets that are the subject
     of this Agreement for other property of like-kind in a non-simultaneous
     exchange ("Non-Simultaneous Exchange") under such terms and conditions as
     qualify for nonrecognition of gain pursuant to Section 1031 of the Internal
     Revenue Code of 1986, as amended.  At Seller's election, made to Buyer
     prior to the transfer of the Assets to Buyer at the Closing and pursuant to
     an assignment in the form of Exhibit F attached hereto and made a part
     hereof (the "Assignment"), Buyer's obligation to pay to Seller at the
     Closing the Purchase Price shall be fulfilled by Buyer's deposit of such
     amount at the Closing in immediately available funds by bank wire transfer
     in a trust established with Chicago Title and Trust Company as trustee,
     pursuant to an exchange trust agreement between Seller and Chicago Deferred
     Exchange Corporation.

     (b)  Buyer agrees to execute a copy of the Assignment and return such copy
     to Seller solely for the purpose of acknowledging receipt of the notice
     from Seller that Seller intends to effectuate the Non-Simultaneous
     Exchange.

                                       19

 
     2.6  Payments Between Parties.  In the event either party ("Recipient")
          ------------------------                                          
receives payments or refunds to which the other party ("Beneficiary") is
entitled in whole or in part under this Agreement, the Recipient shall within
fifteen (15) days from the date of such receipt pay such amount to the
Beneficiary.  All payments to be made under this Section 2.6 or under other
provisions of this Agreement (including Exhibits to be executed and delivered
pursuant to the Agreement) requiring a payment to be made at a time other than
the Closing, shall be made by check or wire transfer in immediately available
funds.

                    ARTICLE III - ALLOCATION OF LIABILITIES
                    ---------------------------------------

     3.1  Known Pre-Closing Liabilities.  Seller has knowledge of certain
          -----------------------------                                  
liabilities and obligations relating to or arising from the ownership,
operation, maintenance or use of the Assets by Seller prior to the Closing.
Such known liabilities and obligations shall be allocated as follows:

     (a)  Seller shall retain, without limit as to time or amount, all liability
     and obligation relating to or arising from Kramer et al. v. Wyco Pipe Line
                                                -------------------------------
     Company, Civil Action No. 91CV2019, District Court, County of Adams, State
     -------                                                                   
     of Colorado (the "Kramer Case").

     (b)  Seller shall retain, without limit as to time or amount, all liability
     and obligation relating to or arising from the "Off-Site Dupont Plume", as
     such term is defined in Schedule 3.1(b) attached hereto and made a part
     hereof, and all liability and obligation

                                       20

 
     relating to or arising from the "Rocky Mountain Arsenal Leak Site", as such
     term is defined in Schedule 3.1(b) attached hereto and made a part hereof,
     provided, however, that Seller shall not be liable or obligated for any
     incremental liability or obligation relating to the Off-Site Dupont Plume
     or the Rocky Mountain Arsenal Leak Site to the extent attributable to (i)
     any failure by Buyer to implement the Agreed Remediation Plan (as such term
     is defined in Section 3.1(c) hereof) in accordance with the time schedules
     set forth in such plan, or negligence in the performance of the Agreed
     Remediation Plan, or (ii) any release, spill, leak, discharge or other
     emission affecting the soil or groundwater attributable to Buyer's
     operations after the Closing.  Such incremental liability or obligation
     shall be Buyer's sole liability.

     (c)  The matters set forth on Schedule 3.1(c)1 attached hereto and made a
     part hereof (the matters so set forth referred to herein as the "Known Pre-
     Closing Contamination") are instances of contamination on the surface or in
     the subsurface or groundwater of the Related Property, in existence on or
     prior to the Closing and attributable to the ownership, operation,
     maintenance or use of the Assets by Seller prior to the Closing, of which
     Seller has sufficient knowledge to develop a plan of remediation.  Seller
     has shared such knowledge with Buyer, and Seller and Buyer have agreed to a
     plan of remediation to be followed for the Known Pre-Closing Contamination,
     which is set forth in Schedule 3.1(c)2 attached hereto and made a part
     hereof (the "Agreed Remediation Plan"), and to the estimated costs
     associated with such Agreed Remediation Plan, which are set forth in
     Schedule 3.1(c)3 attached hereto and made a part hereof.  At the Closing,

                                       21

 
     Seller and Buyer shall each execute and deliver to the other a remediation
     agreement covering remediation of the Known Pre-Closing Contamination,
     substantially in the form attached hereto and made a part hereof as Exhibit
     G (the "Remediation Agreement").

     (d)  The matters set forth on Schedule 3.1(d)1 attached hereto and made a
     part hereof are instances of contamination on the surface or in the
     subsurface or groundwater of the Related Property, in existence on or prior
     to the Closing and attributable to the ownership, operation, maintenance or
     use of the Assets by Seller prior to the Closing, of which Seller has some
     knowledge, but insufficient knowledge to fully develop a plan of
     remediation (the "Schedule 3.1(d) Contamination").  Seller has shared such
     knowledge with Buyer, and Seller and Buyer have preliminarily devised a
     provisional plan of remediation for the Schedule 3.1(d) Contamination,
     which is set forth in Schedule 3.1(d)2 attached hereto and made a part
     hereof, and have preliminarily estimated the costs associated with such
     provisional remediation plan as set forth in Schedule 3.1(d)3 attached
     hereto and made a part hereof.  The present value of such estimated costs
     (using a discount rate of 10%) is seven hundred sixty six thousand and two
     hundred dollars ($766,200).  At such time as, in the case of the Cheyenne
     Terminal contamination reflected on Schedule 3.1(d)1, the relevant State of
     Wyoming Environmental Agency approves a plan of remediation, but in no
     event later than eighteen (18) months after the date of the Closing, and in
     the case of the Rapid City contamination reflected on Schedule 3.1(d)1, the
     relevant State of South Dakota Environmental Agency approves a plan of
     remediation, but in no event later than eighteen (18) months after the date
     of the

                                       22

 
     Closing, Seller and Buyer shall agree as to the plan of remediation to be
     followed for the Schedule 3.1(d) Contamination and as to the estimated
     costs associated with such plan of remediation (including amounts spent
     since the Closing).  If Seller and Buyer are unable to so agree within
     eighteen (18) months of the date of the Closing, the parties will submit
     the unresolved issues to binding arbitration by a single arbitrator under
     the then-existing commercial arbitration rules of the American Arbitration
     Association.  The plan of remediation with respect to the Schedule 3.1(d)
     Contamination and the estimated costs associated with such plan (including
     amounts spent since the Closing), as agreed or determined by arbitration,
     shall be reduced to writing and signed by representatives of Seller and
     Buyer (the "3.1(d) Remediation Plan"), and such writing when so signed
     shall be deemed a part of this Agreement.  At the Closing, Seller and Buyer
     shall each execute and deliver to the other a remediation agreement
     covering remediation of the Schedule 3.1(d) Contamination, substantially in
     the form attached hereto and made a part hereof as Exhibit G (the
     "Remediation Agreement").

     3.2  Unknown Pre-Closing and Other Liabilities.  For purposes of this
          -----------------------------------------                       
Agreement, the term "Unknown Liability" shall refer collectively to the items
described in clauses (i), (ii) and (iii) below, specifically, (i) liability or
obligation relating to or arising from or as a result of a violation of or a
remedial or regulatory obligation imposed under Environmental Law (as such term
is defined in the Remediation Agreement) relating to or arising from or as a
result of an act, event or contamination that occurred or existed at or prior to
the Closing and was attributable or related to the ownership or use of the
Assets prior to the Closing ("Unknown

                                       23

 
Environmental Liability"); (ii) liability or obligation relating to or arising
from the breach of any representation, warranty, covenant or other obligation of
Seller contained in this Agreement, including but not limited to the Remediation
Agreement; and (iii) all other liabilities or obligations of Seller relating to
or arising from the Assets, including, but not limited to, liability or
obligation for third party claims for personal injury or property damage, which
personal injury or property damage was caused by the ownership or use of the
Assets by Seller prior to the Closing, but excluding liabilities and obligations
assumed under the Contracts assigned to Buyer pursuant to the contract
assignment and assumption agreement to be executed by the parties pursuant to
Section 1.4(d) and Article XI hereof, and excluding obligations to be performed
by Buyer pursuant to Section 1.6(d) hereof (the liabilities and obligations
included in this clause (iii) being referred to herein as "Other Liability");
provided that Unknown Liability, Unknown Environmental Liability and Other
Liability shall not include any of the liabilities or obligations retained by
Seller pursuant to Sections 3.1(a) or (b) hereof or any of the costs for
remediation or fines or penalties assumed by or allocated to Buyer under the
Remediation Agreement that are not designated as an Unknown Environmental
Liability under the Remediation Agreement.  This Section 3.2 sets forth the
extent to which and the conditions under which Seller shall retain liability for
Unknown Liability.

     (a)  With respect to Unknown Environmental Liability, if within four and
     one-half (4 1/2) years after the Closing, (i) an Environmental Order (as
     such term is defined in the Remediation Agreement) is issued, the effect of
     which, if not contested, would be to impose a legal obligation to perform
     remediation or to impose other legal liability or

                                       24

 
     obligation pursuant to Environmental Law with respect to any Unknown
     Environmental Liability (or with respect to Known Pre-Closing Contamination
     as set forth in Section 1 of the Remediation Agreement or with respect to
     Schedule 3.1(d) Contamination as set forth in Section 2 of the Remediation
     Agreement) (collectively, an "Order"), or (ii) a third party delivers a
     written statement of claim, the clear purport of which is to assert
     liability or damages against Seller or Buyer relating to any Unknown
     Environmental Liability (a "Claim"), Seller shall retain liability under
     Environmental Law in effect as of the date of the Closing, directly
     relating to or arising from any such Order or to the third party making
     such Claim (except in the case of an Order under the Remediation Agreement,
     Seller shall retain liability only for the incremental cost necessary to
     comply fully with such Order), subject to the following and also to
     subsections (e), (f) and (g) of Section 3.2 hereof and to Section 3.3
     hereof:

          (i)  Promptly upon becoming aware of any facts which have not yet but
     may give rise to such an Order or Claim, Buyer shall provide Seller with
     written notice thereof and the opportunity to participate in discussions
     with the relevant Environmental Agencies (as such term is defined in the
     Remediation Agreement) or third parties relating to such facts, and in
     Seller's sole discretion and at its sole cost to appeal any preliminary
     determination or finding of such Environmental Agencies, provided that,
     subject to clause (ii) below, any delay or failure to provide such notice
     promptly will not limit Seller's liability hereunder except to the extent
     Seller is damaged or prejudiced by such delay or failure; and

                                       25

 
          (ii)  For Seller to have any liability or obligation for any such
     Unknown Environmental Liability, Buyer must give written notice of any such
     Order or Claim, including copies thereof, in no event later than four and
     one-half (4 1/2) years after the Closing (unless Seller otherwise has
     received written notice of such Order or Claim, including a copy thereof,
     prior to the end of such four and one-half (4 1/2) year period, in which
     event Seller shall retain liability and obligation directly relating to or
     arising from such Order or to the third party making such Claim as set
     forth above, subject to subsections (e), (f) and (g) of Section 3.2 and to
     Section 3.3 hereof, and shall promptly give notice of such Order or Claim
     to Buyer). If such written notice is given after the expiration of such
     four and one-half (4 1/2) year period, Seller shall have no liability or
     obligation for such Unknown Environmental Liability, regardless of whether
     Buyer could reasonably have known of such Unknown Environmental Liability
     within such four and one-half (4 1/2) year period (unless Seller otherwise
     has received written notice of such Order or Claim, including a copy
     thereof, prior to the end of such four and one-half (4 1/2) year period, in
     which event Seller shall retain liability and obligation directly relating
     to or arising from such Order or to the third party making such Claim as
     set forth above, subject to subsections (e), (f) and (g) of Section 3.2 and
     to Section 3.3 hereof, and shall promptly give notice of such Order or
     Claim to Buyer); and

          (iii)  If Buyer, subsequent to the Closing, sells, transfers, conveys,
     assigns, sets over, leases or otherwise disposes of any of the Assets or
     any part thereof to any person other than an Affiliate of Buyer (as such
     term is defined in Section 15.14(ii) hereof)

                                       26

 
     ("Resold Assets"), notwithstanding the foregoing, Seller shall have no
     liability or obligation relating to or arising from Unknown Environmental
     Liability associated with such Resold Assets, even if such sale, transfer,
     or other disposition occurs within four and one-half (4 1/2) years after
     the Closing; and

          (iv)  With respect to any particular such Unknown Environmental
     Liability of which (1) Buyer has given written notice to Seller or Seller
     has otherwise received written notice in accordance with clauses (i) and
     (ii) above, and (2) Seller has agreed in writing that such Unknown
     Environmental Liability is an Unknown Environmental Liability for which
     Seller has retained liability in accordance with and subject to the
     provisions of this Agreement, to the extent Seller is fully liable for such
     Unknown Environmental Liability under this Section 3.2, Seller shall have
     the right to perform or have performed at its cost (subject to Section
     3.2(f) below) any required remediation, including dealing with any
     Environmental Agency or Agencies with regard to the corrective action
     required, clean-up standards and appropriate work plans.  With respect to
     any required remediation that Seller elects to perform, Seller may select,
     subject to approval by Buyer (such approval not to be unreasonably
     withheld), one or more environmental consultants to investigate and
     characterize all environmental contamination potentially subject to
     remediation, and to design and perform any required remediation.  Buyer
     shall have the right, at its cost, to participate in the planning and
     design of any required remediation, and Buyer shall be provided, for review
     and comment, a draft of any study, workplan, report or similar document to
     be submitted to an Environmental

                                       27

 
     Agency at least ten (10) working days before Seller intends to submit it.
     Seller will consider in good faith any comments made by Buyer with respect
     to any such study, workplan, report or similar document and, to the extent
     practicable, will incorporate such comments into the document submitted to
     the Environmental Agency. Any required remediation will be designed and
     performed by Seller in a manner that complies with all Environmental Laws,
     minimizes any potential future liability of the site owner/operator, is
     commercially reasonable and cost effective and does not unreasonably
     interfere with Buyer's operations. Seller shall provide Buyer a copy of all
     reports, plans and correspondence submitted to an Environmental Agency with
     respect to an Unknown Environmental Liability or any required remediation
     thereof. In addition, Buyer shall have the right, at its cost, to attend
     and participate in any meetings, conferences or other sessions with the
     Environmental Agency concerning the required remediation and will be
     provided at least ten (10) days' notice of any such meetings (or the
     maximum number of days as is practicable if the meeting date is not set at
     least ten (10) days prior to the meeting). With respect to any remediation
     performed by or on behalf of Seller pursuant to this clause (iv), Seller
     shall be the generator of any wastes generated in connection with such
     remediation and shall prepare all documents associated with such
     remediation in a manner that clearly identifies Seller as the generator of
     the waste, including, but not limited to, the use of identification numbers
     issued to Seller. Upon completion of the required remediation, Seller shall
     provide Buyer written confirmation that the remediation plan designed as
     set forth above has been completed. To the extent that, pursuant to this
     clause (iv), Seller or its representatives or consultants are provided
     access to Buyer's
                                        28

 
     properties or the Pipeline System, Seller shall reimburse Buyer for, and
     defend, indemnify and hold harmless Buyer from and against, any and all
     loss, damage, costs (including reimbursement of all reasonable attorney
     fees and other costs of defense), liability, claim or suit, whether for
     bodily injury or death of any person (including Seller's employees, agents
     and representatives), damage to or destruction or loss of property
     (including damage to Buyer's property), or otherwise, arising in any manner
     whatsoever out of Seller or its representatives or consultants being given
     access to Buyer's properties or the Pipeline System, whether or not based
     upon strict liability or caused by the sole or concurrent negligence
     (ordinary or gross) of Buyer or any other person or entity, unless such
     loss, damage, cost, liability, claim or suit was occasioned solely by the
     negligence or intentional tort of Buyer or any officer, director or agent
     thereof.

          With respect to remediation that Seller has a right to perform
     pursuant to this clause (iv), within ninety (90) days of notice to Seller
     under clause (ii) above, Seller shall notify Buyer whether Seller will
     perform the remediation itself.  If Seller decides to perform the
     remediation itself, Buyer shall cooperate with Seller to effectuate such
     remediation in accordance with this clause (iv), including granting
     reasonable access to the area requiring remediation.  If Seller decides not
     to perform the remediation itself, Buyer shall perform or have performed
     the remediation and invoice Seller for reasonable and necessary costs
     incurred for such remediation (such invoices to include supporting
     documentation).  With respect to any remediation performed by or on behalf
     of Buyer

                                       29

 
     in respect of any Unknown Environmental Liability. Buyer shall be the
     generator of any wastes generated in connection with such remediation and
     shall prepare all documents associated with such remediation in a manner
     that clearly identifies Buyer as the generator of the waste, including, but
     not limited to, the use of identification numbers issued to Buyer.  Subject
     to Section 3.2(f) below, Seller shall pay properly submitted invoices
     within thirty (30) days of receipt, and any such invoice not paid within
     thirty (30) days shall bear interest calculated at a rate equal to the most
     recently quoted (at the time such thirty (30) days expires) one month LIBOR
     rate, compounded annually from the thirtieth (30th) day after receipt of
     the invoice until paid; and

          (v)  Notwithstanding the foregoing, any incremental liability or
     obligation relating to Unknown Environmental Liability to the extent
     attributable to any release, spill, leak, discharge or other emission into
     the environment attributable to Buyer's operations after the Closing, shall
     not be an Unknown Environmental Liability but shall be Buyer's sole
     liability.

     (b)  With respect to liability or obligation relating to or arising from
     the breach of any representation, warranty, covenant or other obligation of
     Seller contained in this Agreement, including but not limited to the
     Remediation Agreement, Seller shall retain such liability and obligation,
     subject to the following and also to subsections (e), (f) and (g) of
     Section 3.2 hereof and to Section 3.3 hereof, except that any breach of any

                                       30

 
     covenant or other obligation of Seller contained in this Agreement and to
     be performed by Seller after the Closing shall not be subject to subsection
     (f) of this Section 3.2:

          For Seller to have any liability or obligation for any such breach of
     any representation, warranty, covenant or other obligation of Seller
     contained in this Agreement, (i) there must be a Buyer Loss (as such term
     is defined in Section 12.1 hereof) attributable to the breach, (ii) Buyer
     must give written notice of any such breach, setting forth the basis of
     such breach known to Buyer at such time in reasonable detail, promptly
     after Buyer has knowledge of such breach, provided that, subject to clause
     (iii) below, any delay or failure to provide such notice promptly will not
     limit Seller's liability hereunder except to the extent Seller is damaged
     or prejudiced by such delay or failure, and (iii) Buyer must give written
     notice of any such breach (other than a breach of any covenant or other
     obligation of Seller contained in this Agreement and to be performed by
     Seller after the Closing) in no event later than four and one-half (4 1/2)
     years after the Closing; if such written notice is given after the
     expiration of such four and one-half (4 1/2) year period, Seller shall have
     no liability or obligation for such breach (other than a breach of any
     covenant or other obligation of Seller contained in this Agreement and to
     be performed by Seller after the Closing), regardless of whether Buyer
     could reasonably have known of such breach within such four and one-half (4
     1/2) year period.

                                       31

 
     (c)  With respect to Other Liability, if within four and one-half (4 1/2)
     years after the Closing, a third party delivers a written statement of
     claim, the clear purport of which is to assert liability or damages against
     Seller or Buyer relating to any Other Liability (a "Demand"), Seller shall
     retain liability and obligation to the third party making such Demand,
     subject to the following and also to subsections (e), (f) and (g) of
     Section 3.2 hereof and to Section 3.3 hereof:

          For Seller to have any liability for any such Other Liability, (i)
     promptly upon becoming aware of any facts which have not yet but may give
     rise to such a Demand, Buyer shall provide Seller with written notice
     thereof and the opportunity to participate in discussions with the relevant
     third parties relating to such facts, provided that, subject to clause (ii)
     below, any delay or failure to provide such notice promptly will not limit
     Seller's liability hereunder except to the extent Seller is damaged or
     prejudiced by such delay or failure, and (ii) Buyer must give written
     notice of any such Demand, including a copy thereof, in no event later than
     four and one-half (4 1/2) years after the Closing (unless Seller otherwise
     has received written notice of such Demand, including a copy thereof, prior
     to the end of such four and one-half (4 1/2) year period, in which event
     Seller shall retain liability and obligation to the third party making such
     Demand as set forth above, subject to subsections (e), (f) and (g) of
     Section 3.2 and to Section 3.3 hereof, and shall promptly give notice of
     such Demand to Buyer); if such written notice is given after the expiration
     of such four and one-half (4 1/2) year period, Seller shall have no
     liability or obligation for such Other Liability, regardless of whether
     Buyer could

                                       32

 
     reasonably have known of such Other Liability within such four and one-half
     (4 1/2) year period (unless Seller otherwise has received written notice of
     such Demand, including a copy thereof, prior to the end of such four and
     one-half (4 1/2) year period, in which event Seller shall retain liability
     and obligation to the third party making such Demand as set forth above,
     subject to subsections (e), (f) and (g) of Section 3.2 and to Section 3.3
     hereof, and shall promptly give notice of such Demand to Buyer).

     (d)  Notwithstanding the foregoing, except to the extent, if any, that any
     breach by Seller of its representations set forth in Sections 7.1(n) and
     (o) hereof relates to the physical condition or configuration of the
     Assets, Seller shall retain no liability or obligation (i) for the physical
     condition or configuration of the Pipeline System as of the Closing, or
     (ii) with respect to any liability or obligation that accrues after the
     Closing and that relates to the physical condition or configuration of the
     Pipeline System as of the date of the Closing, including but not limited to
     any liability or obligation to repair, replace, correct, upgrade,
     refurbish, add to, move, supplement or change any part of the Pipeline
     System.

     (e)  Any and all liabilities and obligations retained by Seller in
     accordance with Sections 3.2(a) through (d) above, before taking into
     account subsections (f) and (g) below, shall be referred to herein as
     "Assigned Liabilities".

                                       33

 
     (f)  Notwithstanding subsections (a) through (d) above, Seller shall have
     no liability or obligation with respect to any Assigned Liabilities until
     the aggregate cost thereof exceeds one hundred and fifty thousand dollars
     ($150,000); the first one hundred and fifty thousand dollars ($150,000) of
     cost of Assigned Liabilities shall be paid by Buyer.  After the aggregate
     cost of all Assigned Liabilities exceeds one hundred and fifty thousand
     dollars ($150,000), as supported with appropriate documentation provided to
     Seller by Buyer, Seller shall be liable and obligated for such Assigned
     Liabilities to the extent, but only to the extent, that the aggregate cost
     of such Assigned Liabilities exceeds $150,000, provided that Seller and
     Buyer shall share equally each dollar of the next nine hundred thousand
     dollars ($900,000.00) of cost of Assigned Liabilities that are Unknown
     Environmental Liability, and provided further that Seller shall not be
     liable or obligated for Assigned Liabilities (including without limitation
     Assigned Liabilities that are Unknown Environmental Liability) to the
     extent the aggregate cost therefor exceeds two million, nine hundred and
     fifty thousand dollars ($2,950,000) plus one-half of the first (after the
     above-mentioned $150,000 is exceeded) $900,000 of Assigned Liabilities that
     are Unknown Environmental Liability (the "Ceiling").  Seller shall not be
     liable or obligated, and Buyer shall be liable and obligated (except for
     those matters for which Seller has retained liability pursuant to Section
     3.3 (a)(i)-(vi) below), for the first $150,000 of Assigned Liabilities and
     for all Assigned Liabilities in excess of the Ceiling, except only if
     Buyer's aggregate cost for Assigned Liabilities, as supported with
     appropriate documentation provided to Seller by Buyer, reaches an amount
     equal to the Purchase Price.

                                       34

 
     The maximum liability and obligation of Seller for Assigned Liabilities
     shall be the Ceiling, except only if Buyer's aggregate liability and
     obligation for Assigned Liabilities reaches an amount equal to the Purchase
     Price, as supported with appropriate documentation provided to Seller by
     Buyer, at which point liability and obligation for further Assigned
     Liabilities to the extent above an amount equal to the Purchase Price shall
     revert to and be retained by Seller.  The maximum liability and obligation
     of Buyer for Assigned Liabilities shall be an amount equal to the Purchase
     Price.  Liabilities and obligations assumed or incurred by Buyer related to
     the Assets that are not Assigned Liabilities shall not count towards either
     the $150,000 deductible provided for in this subsection (f) or towards the
     Purchase Price cap on Buyer's liability and obligation for Assigned
     Liabilities.  At such time, if any, as Buyer reasonably determines that its
     aggregate liability and obligation for Assigned Liabilities will reach an
     amount equal to the Purchase Price, it shall provide Seller with written
     notice thereof and shall make available to Seller supporting documentation
     reasonably satisfactory to Seller.

          Notwithstanding the foregoing, the Ceiling shall not apply to any
     Assigned Liabilities relating to or arising from the breach of Section
     7.1(d).  Notwithstanding the foregoing, the Ceiling and the one hundred and
     fifty thousand dollar ($150,000) deductible provided for in this subsection
     (f) shall not apply to any Assigned Liabilities relating to or arising from
     any breach by Seller of any covenant or other obligation of Seller
     contained in this Agreement and to be performed by Seller after the
     Closing.  Notwithstanding any required notice provisions in Section 3.2(a),
     (b) or (c), any

                                       35

 
     individual Assigned Liability that is paid by Buyer within four and one-
     half (4 1/2) years after the Closing, in an amount less than ten thousand
     dollars ($10,000), and for which notice was not given in accordance with
     Section 3.2(a), (b) or (c), whichever applies, but for which Buyer could
     have given the required notice to Seller within four and one-half (4 1/2)
     years after the Closing, will be counted toward the one hundred and fifty
     thousand dollar ($150,000) deductible provided for in this subsection (f)
     if proper notice thereof is given to Seller at the time Buyer requests
     payment by Seller hereunder of Assigned Liabilities.

          For purposes of this Agreement, time expended by personnel of Seller
     or Buyer, or affiliates of either, in connection with Assigned Liabilities
     shall not be considered a cost of Assigned Liabilities.  Reasonable
     attorneys' and consultants' fees incurred in connection with an Assigned
     Liability by the party that, pursuant to the provisions of this Agreement,
     is responsible for dealing with the Assigned Liability, shall be considered
     a cost of Assigned Liabilities for purposes of this Agreement; otherwise
     attorneys' fees and consultants' fees shall not be considered a cost of
     Assigned Liabilities.

     (g)  Other than liability and obligation for Assigned Liabilities within
     the limitations set forth in subsections (a) through (f) above, and for
     liability and obligation retained by Seller under either Section 3.1,
     Section 3.3 or the Remediation Agreement, Seller shall have no liability or
     obligation relating to or arising from the Assets, or the ownership,

                                       36

 
     operation or use thereof, including without limitation Unknown
     Environmental Liability and Unknown Liability.

     3.3  Liabilities Assumed by Buyer; Liabilities of Buyer.

     (a)  Buyer hereby assumes all liabilities and obligations of Seller

     assume or be deemed to have assumed, and Seller shall retain liability for
     and indemnify Buyer against, all liabilities, damages, costs (including
     reasonable attorneys' fees) arising from or related to the following,

     employees, representatives or agents after the Closing, provided that the
     indemnity of Seller with respect to such acts or omissions that constitute
     a breach of any representation or warranty of Seller contained in this
     Agreement shall be limited as set forth in subsections (e), (f) and (g) of
     Section 3.2 hereof; and

          (vi)   liabilities or obligations of Seller relating to or arising
     from wilful or intentional violation of laws, rules, regulations or
     governmental directives or pronouncements by Seller or its affiliates,

     arising from Buyer's acts, events or omissions, or contamination, occurring
     after the Closing, shall be liabilities and obligations of Buyer.

     3.4  Notice by Seller.  If Seller, or either of its shareholders, Amoco
          ----------------                                                  
Pipeline Holding Company and GATX Pipeline Company, receives a Claim or a Demand
from a third party, Seller shall promptly send a copy of such to Buyer and shall

relating to termination of such Employees, except that if, within one hundred
and twenty (120) days of the Closing, Buyer hires any Employee who received

     and in good standing under the laws of the State of Delaware, and is
     qualified as a foreign corporation in each jurisdiction in which the

     obligations hereunder or thereunder).

     (b)  Authorization.  Seller has requisite corporate power and authority to

          (B)  result in a breach or default of, or result in the creation or
     imposition of any lien or encumbrance upon the Assets under, any agreement
     or commitment to which Seller is a party or by which Seller or any of the
     Assets is bound; or

          (C)  to the knowledge of Seller, violate any statute or law or any

     liability with respect to any employee welfare or benefit plans of APL or
     Seller, as a result of the transactions contemplated by this Agreement.

                                       47

 
     does not now nor has it ever contributed to, a "multiemployer plan" as
     defined in section 4001(a)(3) of the Employee Retirement Income Security
     Act of 1974, as amended ("ERISA") with regard to any Employee which would
     result in any liability to Buyer.  Neither Seller nor such employer nor any
     trustee, administrator, fiduciary, agent or employee thereof has at anytime
     been involved in a transaction that would constitute a "prohibited
     transaction" within the meaning of Section 406 of ERISA which would subject
     the Buyer or any of its affiliates or any of its or their officers,
     directors or employees to any taxes, penalties or other liabilities under
     section 4975 of ERISA or under Sections 409 or 502(i) of ERISA.  To the

     reporting, tax or similar purposes, or for purposes of investigating
     matters which may be the subject of litigation or administrative
     proceedings with third parties or governmental agencies, so long as such
     disclosure would not violate the terms of any agreement to which Seller is

     under or pursuant to such Amoco Oil Contract, and agrees to perform,
     discharge and comply with all terms and conditions of or under such Section

     which is item no. 14 on Schedule 1.1(e)), Buyer agrees to cooperate with
     Sinclair in regard to environmental matters affecting said Related Property
     and to inform Sinclair within twenty-four (24) hours of any release, spill,

     event that Buyer decides to change the direction or type of material
     through the Pipeline, or alter in any material way the Pipeline or its
     operations, Buyer agrees that it will inform Sinclair in writing of any
     such plans as far in advance as is practicable.  The obligations of Buyer

                                       64

     to accomplish such, provided that in no event shall the Closing be
     affected.

     parent companies, shareholders, partners, subsidiaries, affiliates,
     officers, directors, employees or agents (all of the foregoing collectively
     referred to herein as a "Buyer Loss"), regardless of whether based in whole
     or in part on strict liability, willful or intentional misconduct, or
     ordinary or gross negligence of any indemnitee, which arise out of, relate
     to or are caused by any liability or obligation retained by Seller under
     this Agreement.

     Seller's obligation of indemnification in this Section 12(a) is subject to
     the allocation of liability set forth in Article III hereof.

     (b)  From and after the Closing, but subject to Section 12.3 hereof, Seller
     shall indemnify Buyer, together with Buyer's parent companies,

     failure; and

          (iii)  Seller's maximum liability under this Section 12(b) shall be

Seller, its parent companies, shareholders, subsidiaries, affiliates, officers,
directors, employees or agents, regardless of whether based in whole or in part
on strict liability, willful or intentional misconduct, or ordinary or gross
negligence of any indemnitee, which arise out of, relate to or are caused by:
(a) the breach of any representation, warranty, covenant or other obligation of
Buyer contained in this Agreement, including but not limited to the Remediation
Agreement and the contract assignment and assumption agreement to be executed by
the parties pursuant to Section 1.4(d) and Article XI hereof; (b) any duty,
liability or obligation assumed or had by Buyer pursuant to Section 3.1, Section

extent attributable to (i) actions of Buyer or its agents, consultants or
representatives in the implementation or performance of the Agreed Remediation

Buyer and Seller, or (ii) any failure by Buyer to implement the Agreed
Remediation Plan or the 3.1(d) Remediation Plan, as they may be modified with
the consent of Buyer and Seller, in accordance with the time schedules set forth
in such plans, or negligence in the performance of the Agreed Remediation Plan
or the 3.1(d) Remediation Plan, as they may be modified with the consent of
Buyer and Seller.

its parent companies, shareholders, subsidiaries, affiliates, officers,
directors, employees and agents as set forth above in this Section 12.2 shall
survive the Closing without limit as to time or amount, except as limited by
Sections 3.2(f) and 3.3 hereof.  Buyer's obligation of indemnification in this
Article XII is subject to the allocation of liability set forth in Article III
hereof.

     12.3  Procedure for Third Party Claims.
           -------------------------------- 

     (a)  If any third party shall notify Seller or Buyer (the "Indemnified
     Party") with respect to any matter which may give rise to a claim for
     indemnification against the other party under this Agreement (the
     "Indemnifying Party") then the Indemnified Party shall notify the
     Indemnifying Party thereof promptly in writing; provided, however, that,
                                                     --------  -------       
     subject to Article III, no delay in giving notice of such matter shall
     relieve the Indemnifying Party from any obligation hereunder unless (and
     then solely to the extent) the Indemnifying Party is thereby damaged or the
     defense of any matter for which indemnification is claimed is prejudiced.
     The Indemnifying Party shall notify the Indemnified Party in writing within
     fifteen (15) days of receiving such notice whether the Indemnifying Party
     accepts responsibility for such matter.  If (i) the Indemnified Party does
     not receive timely written notice that the Indemnifying Party accepts
     responsibility for such matter, or (ii) if the Indemnifying Party accepts
     responsibility but fails to diligently defend the Indemnified Party in such
     matter, or (iii) if in the reasonable opinion of the Indemnified Party the
     Indemnifying Party may lack the financial resources necessary to comply
     with

                                       78

 
     its indemnity obligations in connection with such matter, then the
     Indemnified Party may defend against or enter into any settlement with
     respect to, such matter as it deems appropriate without relieving the
     Indemnifying Party of any of its indemnification obligations with respect
     to such matter.  If the Indemnifying Party assumes responsibility for the
     matter, then (A) the Indemnifying Party will defend the Indemnified Party
     against the matter with counsel and consultants of its choice reasonably
     satisfactory to the Indemnified Party, (B) the Indemnifying Party shall
     have, subject to this Section 12.3, exclusive control of the defense and
     settlement of the matter, (C) the Indemnified Party may retain separate co-
     counsel and consultants at its sole cost, and (D) the Indemnifying Party
     will not consent to the entry of any judgment or enter into any settlement
     with respect to the matter which does not include a provision whereby the
     plaintiff or claimant in the matter releases the Indemnified Party from all
     liability with respect thereto at no cost to, and with no actions required
     by and no future obligations imposed on, the Indemnified Party except for
     such as may be agreed to in writing by the Indemnified Party.

     (b) The Indemnified Party and the Indemnifying Party shall use their
     reasonable efforts to cooperate, without prejudice to any rights they may
     have against each other, in the compromise or defense of any third party
     claim which is not entirely subject to indemnification by a single
     Indemnifying Party.

                                       79

 
     12.4  Exclusive Remedy.  The provisions of this Article XII, the provisions
           ----------------                                                     
of Article III, and the corresponding provisions in the Transfer Documents, if
any, are intended to be the exclusive remedy between the parties for the matters
covered by such provisions, and no party shall seek recovery from the other
party with respect to such matters under theories of strict liability,
negligence or other theory of recovery, whether under contract (other than under
this Article XII, Article III or the corresponding provisions of any Transfer
Document) or tort or at law or in equity.

     15.9  Entire Agreement.  This Agreement, including the Schedules and
           ----------------                                              
Exhibits hereto, the Transfer Documents, the Confidentiality Agreement and the
letter agreement relating to the two mortgages on the Mule Creek Station Related
Property constitute the entire agreement between the parties hereto pertaining
to the subject matter hereof and supersede all prior agreements, understandings,
negotiations and discussions, whether oral or written, of the parties relating
to the subject matter hereof.  There are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof
except as specifically set forth herein or in the Schedules and Exhibits hereto
or in the Transfer Documents or the Confidentiality Agreement.  No supplement,
modification, waiver or termination of this Agreement or any Schedule or Exhibit
shall be binding unless executed in writing by the party to be bound thereby.

     15.10  Severability.  If any provision of this Agreement shall hereafter be
            ------------                                                        
held to be invalid or unenforceable for any reason, that provision shall be
reformed to the maximum extent permitted to come as close as possible in its
effects to the invalid or unenforceable provision, failing which, it shall be
ineffective to the extent of such invalidity or unenforceability only, with the
balance of the provision and of the Agreement continuing in full force and
effect.  Such occurrence shall not have the effect of rendering the provision in
question invalid in any other jurisdiction or in any other case or
circumstances, or of rendering invalid any other provisions contained herein to
the extent that such other provisions are not themselves actually in conflict
with any applicable law.
