ITEM 5.  ACQUISITION OR DISPOSITION OF ASSETS.


         On August 27, 1995, the Partnership, through its operating
partnership, signed definitive purchase agreements to acquire from Steuart
Petroleum Company and certain of its affiliates (collectively, "Steuart") the
liquids terminaling assets of Steuart.  It is anticipated that the acquisition
price of approximately $82 million will be financed by bank borrowings.  The
Steuart terminaling assets consist of seven petroleum products terminals
located in the District of Columbia, Florida, Georgia, Maryland and Virginia
and the pipeline and terminaling services to Andrews Air Force Base in
Maryland.  The terminals have in the aggregate approximately 9 million barrels
of storage capacity in 87 tanks.  Steuart's two largest facilities are located
near Washington, D.C. and Jacksonville, Florida.  The Piney Point, Maryland
terminal is the closest deep water petroleum storage facility to Washington
D.C.  The Piney Point Maryland terminal has 30 tanks with approximately 5.5
million barrels of aggregate storage capacity, which is currently used to store
petroleum products,consisting primarily of fuel oil.  The Jacksonville terminal
has 28 tanks with approximately 2.1 million barrels of aggregate storage
capacity, which is currently used to store petroleum products including
gasoline, No. 2 oil, No. 6 oil, diesel, jet fuel, kerosene and bunker fuel.

         The closing of the Steuart acquisition is conditioned upon
satisfactory completion of a due diligence investigation, receipt of all
necessary consents and approvals, the execution of certain throughput
agreements and certain other conditions.  If all conditions to closing are
satisfied, it is anticipated that the Partnership would acquire the Steuart
terminals prior to October 31, 1995.  There can be no assurance, however, that
the acquisition will be consummated or, if consummated, that the terms of the
acquisition will not vary materially from those described herein.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Boards of Directors of
Steuart Petroleum Company and
Steuart Investment Company

We have audited the accompanying statements of revenues and direct operating
expenses of SPC/SIC - Terminal Operations Division for the year ended December
31, 1992 and  the period from January 1, 1993 to June 8, 1993.  These financial
statements are the responsibility of the Division's management.  Our
responsibility is to express an opinion on these statements based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the statements of revenues and direct
operating expenses are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
these statements.  An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall presentation of these statements.  We believe that our audits provide a
reasonable basis for our opinion.

As described in Note 1, the accompanying statements were prepared to present
the revenues and direct operating expenses attributable to SPC/SIC - Terminal
Operations Division, and are not intended to be a complete presentation of the
revenues and expenses of SPC/SIC - Terminal Operations Division.

In our opinion, such statements of revenues and direct operating expenses
present fairly, in all material respects, the revenues and direct operating
expenses of SPC/SIC - Terminal Operations Division for the year ended December
31, 1992 and the period from January 1, 1993 to June 8, 1993 in conformity with
the basis of presentation described in Note 1 and generally accepted accounting
principles.

NOTE 1 - BASIS OF PRESENTATION

Kaneb Pipe Line Partners, L.P. ("KPP") expects to enter into agreements with
Steuart Petroleum Company ("SPC" or the "Company," a wholly-owned subsidiary of
Steuart Investment Company) and Steuart Investment Company ("SIC"), the
sellers, to acquire certain of the assets and assume certain of the liabilities
relating to the business of the terminal operations division of SPC, the
terminal operations and pipeline business of SIC and the partnership interest
of SPC Terminals Inc. (a wholly-owned subsidiary of Steuart Petroleum Company -
see Note 7).  Such purchased net assets to be acquired are collectively
referred to herein as SPC/SIC - Terminal Operations Division or "Division."
The Division is engaged principally in the terminal storage and throughput
services business.

The assets to be acquired include five terminals (located in Piney Point,
Maryland; Washington, D.C. (2); Cockpit Point, Virginia and Jacksonville,
Florida) and a pipeline in Maryland.  The businesses also include two leased
terminals (located in Brunswick, Georgia and Savannah, Georgia - see Note 7).

The accompanying special-purpose financial statements include the net assets to
be acquired and related revenues and direct operating expenses of the Division
and are not intended to be a complete presentation of the assets, liabilities
or the results of operations of the sellers or the Division on a stand-alone
basis.  These financial statements do not reflect the revaluation of assets and
liabilities to be acquired by KPP to their fair market value at the date of
acquisition.  The statements have been prepared in accordance with generally
accepted accounting principles and were derived from the historical accounting
records of SPC and SIC.

The statements of net assets to be acquired include the net assets of SPC and
SIC which are directly related to the businesses to be acquired.  As a result,
the statements do not include cash, accounts and notes receivable, prepaid
expenses, accounts payable and accrued expenses and borrowings.

The statements of revenues and direct operating expenses include the revenue
and expenses directly attributable to the businesses, and also include an
allocation of certain expenses directly attributable to the businesses which
have been historically segregated by SPC and SIC in their accounting records.

Full historical financial statements, including certain general and
administrative expenses and other indirect expenses, interest expense and
income taxes, have not been presented due to the fact that management believes
it is not practicable to determine that portion which is attributable to the
Division.  Management of the sellers believes the basis of allocating all other
expenses to be reasonable; however, the amounts could differ from amounts that
would be determined if the Division were operated on a stand-alone basis.  In
addition, centralized cash accounts for the majority of
<PAGE>   10
                                     -2-

disbursements exist at the sellers.  As a result, statements of cash flows have
been excluded from the financial statements.

The statement of net assets to be acquired as of June 30, 1995 and the
statements of revenues and direct operating expenses for the six months ended
June 30, 1995 and 1994 are unaudited; however, in the opinion of management
these statements reflect all adjustments, consisting of only normal recurring
adjustments, necessary for a fair presentation of these statements.

See Note 3 for a summary of the new basis of accounting.

NOTE 2- SIGNIFICANT ACCOUNTING POLICIES

Revenues

Revenues are recognized based upon contractual agreements relating to product
storage and transfer.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost.  Depreciation charges are
computed by straight-line methods over the following useful lives:

                          Buildings and improvements    5-33 years
                          Machinery and equipment       3-20 years
                          Leasehold improvements        4-32 years

Maintenance and repairs are expensed as incurred; significant renewals and
betterments are capitalized.  Maintenance and repair expense included in sales
and operations expenses for the year ended December 31, 1992, the period from
January 1, 1993 to June 8, 1993, the period from June 9, 1993 to December 31,
1993 and for the year ended December 31, 1994 was $1,697, $693, $1,581 and
$2,256, respectively.

Environmental matters

Environmental expenditures that relate to current operations are primarily
expensed as incurred.  The Division has recorded a liability ($1,240, $850 and
$850 (unaudited) at December 31, 1993 and 1994 and June 30, 1995,
respectively), and a receivable for reimbursements ($748, $300 and $300
(unaudited) at December 31, 1993 and 1994 and June 30, 1995, respectively), for
future environmental costs.  The Division's policy is to record a liability
when costs of remediation and/or cleanup of known environmental problems are
probable and the costs can be reasonably estimated.  The Division's policy is
to record available reimbursements when qualification for reimbursement from
state funds is probable under various state laws and regulations.  The portion
of the costs and reimbursements expected to be incurred and received beyond one
year are classified as noncurrent liabilities and other assets.

NOTE 3 - NEW BASIS OF ACCOUNTING

Prior to June 9, 1993, SPC was fifty percent owned by SIC and fifty percent
owned by American AGIP Co., Inc. ("AGIP"), a wholly-owned subsidiary of AGIP
Petroli International, B.V., a Netherlands corporation whose ultimate sole
parent is Ente Nazionale Idrocarburi, an industrial conglomerate organized
under the laws of the Republic of Italy.  Following the close of business on
June 8, 1993, SPC retired all of its existing common stock and redeemed the
shares previously held by AGIP.

The redemption of the common stock of the Company previously held by AGIP
resulted in the Company becoming wholly-owned by SIC, and therefore a new basis
of accounting was established.  Consequently, the accompanying statements of
revenues and direct operating expenses include the year ended December 31, 1992
and the period from January 1, 1993 to June 8, 1993 (old basis) and the period
from June 9, 1993 to December 31, 1993, the year ended December 31, 1994 and
the six months ended June 30, 1995 and 1994 (new basis).

The consequences of establishing a new basis of accounting at June 9, 1993
included an increased adjustment to the carrying value of buildings and
improvements of $22,507.  Differences in estimates made in establishing the
original new basis allocation resulted in an additional $2,270 increase in the
carrying value of buildings and improvements in 1994.

NOTE 4 - PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment (primarily petroleum terminaling and storage
facilities) are carried at cost and consist of the following:

</TABLE>



Effective February 1995, Defense Fuel Supply Center terminated one of its two
contracts with the Division prior to its scheduled expiration in June 1996.
The terminated contract provided for minimum annual revenues of approximately
$1,400.

NOTE 6 - EMPLOYEE BENEFIT PLANS

The sellers maintain profit-sharing plans that covers substantially all
employees.  Contributions, which are made to the plans solely at the discretion
of the sellers' Boards of Directors, amounted to $113, $63, $83 and $208 for
the year ended December 31, 1992, the period from January 1, 1993 to June 8,
1993, the period from June 9, 1993 to December 31, 1993 and for the year ended
December 31, 1994, respectively.  Benefits are payable to employees upon
retirement, disability or termination based upon their accumulated credits in
accordance with the provision of the plans.  The plans may be terminated at the
option of the sellers.  The sellers also maintain a 401(k) retirement plan
whereby they match a portion of the employees' contributions.  The Division's
contributions to the plan amounted to $15, $6, $9 and $72 for the year ended
December 31, 1992, the period from January 1, 1993 to June 8, 1993, the period
from June 9, 1993 to December 31, 1993 and for the year ended December 31,
1994, respectively.

NOTE 7 - JOINT VENTURE

On May 27, 1994, SPC formed SPC Terminals Inc. (STI) as a wholly-owned
subsidiary.  On this date, STI entered into a general partnership agreement
with Aectra Terminals Inc. (ATI) and formed Steuart-Aectra Terminals
Partnership No. 1 (SAT #1), which purchased a petroleum bulk terminal located
in Savannah, Georgia.  Each partner has a 50% interest in the partnership.
STI's investment in SAT #1 is accounted for under the equity method.  In 1994,
STI recorded a loss of $75 representing its approximate share of SAT #1 losses.

The Division has a five year lease on this terminal from SAT #1 expiring May
31, 1999 for the cost of the property insurance.  During 1994, the Division
incurred approximately $17 in rent expense in connection with the lease.  The
Division also has a five year throughput agreement with Aectra Refining

<PAGE>   13
                                     - 5 -

and Marketing (Aectra) expiring May 31, 1999, whereby Aectra has agreed to
throughput a minimum amount of gasoline, gasoline components and distillates
each year at this terminal.

At December 31, 1994, SAT #1 had total assets of $1,816 (principally property,
plant and equipment), liabilities of $1,766 and partnership equity of $50.  SAT
#1 incurred a net loss of $150 for the period from May 27, 1994 to December 31,
1994.

NOTE 8 - RELATED PARTY TRANSACTIONS

The Division provides terminal storage and throughput services to the marketing
division of SPC.  Revenue from such services amounted to $2,141, $989, $1,353
and $2,800 for the year ended December 31, 1992, the period from January 1,
1993 to June 8, 1993, the period from June 9, 1993 to December 31, 1993 and for
the year ended December 31, 1994, respectively.

The Division also provides office space to other divisions of SPC.  Rental
revenues amounted to $199, $74, $35 and $95 for the year ended December 31,
1992, the period from January 1, 1993 to June 8, 1993, the period from June 9,
1993 to December 31, 1993 and for the year ended December 31, 1994,
respectively.

                KANEB PIPE LINE PARTNERS, L.P. AND SUBSIDIARIES

                  PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

   In February 1995, Kaneb Pipe Line Partners, L.P. (the "Partnership")
acquired, through its operating partnership, the refined petroleum product
pipeline assets (the "West Pipeline") of Wyco Pipe Line Company for $27.1
million.  The West Pipeline was owned 60% by a subsidiary of GATX Terminals
Corporation and 40% by a subsidiary of Amoco Pipe Line Company.  The
acquisition was financed by the sale of $27 million of first mortgage notes to
three insurance companies.  The assets acquired from Wyco Pipe Line Company did
not include certain assets that were leased to Amoco Pipe Line Company, and the
purchase agreement did not provide for either (i) the continuation of an
arrangement with Amoco Pipe Line Company for the monitoring and control of
pipeline flows or (ii) the extension or assumption of certain credit agreements
that Wyco Pipe Line Company had with its shareholders.

   On August 27, 1995, the Partnership agreed to purchase the liquids
terminaling assets from Steuart Petroleum Company and certain of its affiliates
(collectively, "Steuart").  The acquisition price of $82 million will be
financed by bank borrowings.  The asset purchase agreement includes a provision
for an earn-out payment based upon revenues of one of the terminals exceeding a
specified amount for a seven year period beginning in 1996.  The contracts also
include a provision for the continuation of all terminaling contracts in place
at the time of the acquisition, including those contracts with Steuart.  The
closing of the acquisition is conditional upon satisfactory completion of a due
diligence investigation, receipt of all necessary consents and approvals, the
execution of certain throughput agreements and certain other conditions.  If
all conditions to the closing are satisfied, it is anticipated that the
Partnership would acquire the liquids terminaling assets from Steuart prior to
October 31, 1995.  There can be no assurance that the acquisition will be
consummated or, if consummated, that the terms of the acquisition will not vary
materially from those described herein.  The acquisition, if consummated, will
be accounted for using the purchase method of accounting.  The total purchase
price will be allocated to the assets and liabilities based on their respective
fair values based on valuations and other studies which are not yet completed. 
The allocation of the purchase price presented in the unaudited pro forma
consolidated financial statements is preliminary and subject to adjustment.

   The following unaudited pro forma financial statements of the Partnership
have been derived from (i) the historical financial statements of the
Partnership as of June 30, 1995 and for the year ended December 31, 1994 and
the six-month period ended June 30, 1995, (ii) the historical financial
statements of Wyco Pipe Line Company for the year ended December 31, 1994 and
the period ended February 24, 1995, and (iii) the statements of revenues and
direct operating expenses for the year ended December 31, 1994 and the
six-month period ended June 30, 1995 and the statements of net assets to be
acquired as of June 30, 1995 of SPC/SIC -- Terminal Operations Division.  The
following unaudited pro forma financial statements have been compiled as if the
Partnership acquired the pipeline assets of the West Pipeline and the liquids
terminaling assets of Steuart as of the beginning of the period for income
statement purposes and as of June 30, 1995 for balance sheet purposes.  The
unaudited pro forma financial statements should be read in conjunction with the
notes accompanying such unaudited pro forma financial statements and with the
historical financial statements and related notes of the Partnership the
historical financial statements and related notes of Wyco Pipe Line Company and
the historical statements of revenues and direct operating expenses and
statements of net assets to be acquired and related notes of SPC/SIC --
Terminal Operations Division.

   The unaudited pro forma financial statements may not be indicative of the
results that would have occurred if the Partnership had acquired the pipeline
assets of the West Pipeline and the liquids terminaling assets of Steuart on
the dates indicated or which will be obtained in the future.

Closing shall be the responsibility of Purchaser). Notwithstanding the
foregoing, if Purchaser does not purchase





                                       16
<PAGE>   22
the Cockpit Point Real Property from SIC under the Cockpit Agreement at the
Closing, Purchaser shall only be obligated to assume the Cockpit Point Real
Estate Lease if it is modified in the manner set forth in Section 3.12;

                          (ii)    if the Partnership Interest is purchased
hereunder, SPCT's obligations and liabilities under the Partnership Agreement
attributable to periods of time commencing with the Closing, provided however,
that Purchaser specifically does not assume, and shall not be treated as having
assumed, any liability or obligation that relates to or arises out of a breach
of the Partnership Agreement that occurs prior to Closing (provided that
liability and obligation for Purchaser's continuing breaches of the Partnership
Agreement after Closing and liability and obligation for breaches of the
Partnership Agreement commenced by Purchaser after Closing shall be the
responsibility of Purchaser); and

                          (iii)   except as expressly provided for otherwise
herein and in accordance with the provisions of Section 11.7, any amounts
payable to perform Remedial Work with respect to the Acquired Assets or the
Business, regardless of when the events giving rise to the obligation to
perform such Remedial Work are alleged to have occurred.

         The obligations assumed by Purchaser pursuant to subsection (a) of
this Section 2.2 are referred to herein collectively as the "Assumed
Liabilities".

                 (b)      Purchaser shall not assume (i) any liabilities or
obligations of SPC or the Subsidiaries not specifically assumed under
subsection (a) of this Section 2.2, except to the extent that Purchaser's
covenants in Section 11.7 constitute an assumption of such liabilities or
obligations, or (ii) any liabilities or obligations associated with the
northern or southern marketing divisions.  Nothing herein shall be deemed to
contravene the Purchaser's





                                       17
<PAGE>   23
indemnification of SPC in Sections 11.3 and 11.7, which shall remain in full
force and effect.  Without in any way limiting the foregoing, the parties agree
that the Purchaser does not and will not assume the sponsorship of, or the
responsibility for contributions to, or any liability in connection with, any
employee pension benefit plan, any employee welfare benefit plan, or other
employee benefit agreement or arrangement maintained by SPC for its employees,
former employees, retirees, their beneficiaries or any other Person.  In
addition and not as a limitation of the foregoing covenant, the parties agree
that SPC shall be liable for any continuation coverage (including any
penalties, excise taxes or interest resulting from the failure to provide
continuation coverage) required by Section 4980B of the Code due to qualifying
events which occur on or before the Closing Date.  Notwithstanding the
foregoing,  Purchaser shall provide health and medical benefits under its then
existing plans, effective as of the date of hire, for each SPC employee that is
hired by Purchaser.

         Section 2.3      Payment of Purchase Price.  The consideration for the
sale of the Acquired Assets shall be the Purchase Price, the Earn-Out described
in Section 2.3.2, and the assumption by the Purchaser of the Assumed
Liabilities.

                 2.3.1    At Closing.  At the Closing, Purchaser shall pay for
the Acquired Assets the sum of Seventy Five Million Nine Hundred Nineteen
Thousand Dollars ($75,919,000) (the "Purchase Price") , or the Adjusted
Purchase Price, as the case may be, which amount shall include the sum of Five
Million Dollars ($5,000,000) paid to the Escrow Agent pursuant to the Escrow
Agreement described in Section 11.4.  Notwithstanding any provision contained
herein that may be construed to the contrary, any adjustment to the Purchase
Price pursuant to the terms of the PPI Agreement (other than Section 12.14) and
the Cockpit Agreement shall be





                                       18
<PAGE>   24
calculated as part of the Aggregate Adjusted Purchase Price for purposes of
determining SPC's right to terminate this Agreement pursuant to Section 10.1(c)
hereto.

                 2.3.2    Earn-Out.  With respect to the Terminal at Piney
Point, Purchaser shall pay SPC an earn-out for each of the seven calendar years
commencing January 1, 1996, equal to forty percent (40%) of the net revenues in
such year in excess of $10,250,000 (the "Earn-Out"), as set forth more fully in
Exhibit 2.3.2.

         Section 2.4      Allocation of Purchase Price Amongst Acquired Assets.
The Purchase Price shall be allocated amongst the Acquired Assets in accordance
with the fair market values set forth on Schedule 2.4.  Neither party shall
take any position inconsistent with Schedule 2.4 in any filing with the
Internal Revenue Service or for any other purpose.

         Section 2.5      Allocation of Purchase Price Amongst Terminals.  The
Purchase Price shall be allocated amongst the individual Terminals, which
allocation shall include all of the  Acquired Assets located at each  Terminal,
in accordance with the fair market values set forth on Schedule 2.5.

         Section 2.6      Payment of Taxes and Closing Costs.  Purchaser shall
be responsible for and shall pay any and all state sales taxes (except with
respect to any sales tax in Virginia, which shall be shared equally by SPC and
Purchaser) arising in connection with the sale of the Acquired Assets.  All
closing costs in connection with the sale of the Real Estate or transfer of the
rights under the Right-of-way Agreements, including transfer taxes and
recording fees, shall be paid equally by SPC and Purchaser, except that title
insurance premiums shall be paid by Purchaser.

         Section 2.7      Risk of Loss.





                                       19
<PAGE>   25
                 (a)      The risk of loss of the Acquired Assets shall pass to
Purchaser at Closing.  If there is any loss, damage, breakdown, or casualty to
any of  the Acquired Assets prior to Closing that does not constitute either
(i) a loss, damage, breakdown, or casualty that has been repaired or replaced
to the reasonable satisfaction of Purchaser, or (ii) a loss, damage, breakdown,
or casualty fully covered by insurance proceeds which have been assigned to
Purchaser and insurance retentions paid by SPC to Purchaser, the Purchase Price
shall be reduced by the cost to repair or replace such assets, estimated if
necessary.  If there is reasonable doubt whether a loss, damage, breakdown, or
casualty is fully covered by insurance and the payment of insurance retentions
by SPC, Purchaser may reduce the Purchase Price by the cost of repairing or
replacing such assets, in which case SPC shall not assign the insurance
proceeds or pay any insurance retentions to Purchaser.  The cost of repairing
or replacing such assets shall be such cost or estimated cost as is agreed upon
between the parties.

                 (b)      Notwithstanding the above provisions of this Section
2.7, if any repair or replacement is reasonably expected to cause the Average
Monthly Revenue at an affected Terminal to decrease by five percent (5%) or
more during the month immediately following Closing, Purchaser may, in lieu of
accepting insurance proceeds and any insurance retentions or a reduction in the
Purchase Price, delay the Closing on the portion of the Acquired Assets
constituting such Terminal until SPC has completed such repair or replacement
to the reasonable satisfaction of Purchaser, provided, however, that if
Purchaser elects to delay the Closing for a particular Terminal or Terminals,
SPC may elect to delay the Closing with respect to all of the Acquired Assets
until such repair or replacement has been completed.  If the Purchaser elects
to delay the Closing pursuant to the preceding sentence, then (unless SPC is
entitled to and elects





                                       20
<PAGE>   26
to terminate this Agreement pursuant to Article 10), SPC shall promptly and
diligently cause such repair or replacement to be completed to the reasonable
satisfaction of Purchaser.

                                   ARTICLE 3

                            MATTERS PRIOR TO CLOSING

         Section 3.1      Due Diligence.

                 3.1.1    Examination of Records and Assets.  During the Due
Diligence Period, (i) Purchaser and its agents may examine the Business, the
Acquired Assets, and such books, records, files, and documents of the Company
or the Subsidiaries as relate to the Business or the Acquired Assets, (ii) the
Company shall make available to Purchaser and its agents for review all
information concerning the Acquired Assets or the Business which they may
request, and (iii) the Company will make available to Purchaser the officers
and any key employees of the Company to answer questions and to discuss the
Company and its Business, all in a manner that does not unduly disrupt the
Business.  If the Closing does not occur, Purchaser shall promptly return to
the Company or the Subsidiaries, as appropriate, at Purchaser's expense, (i)
all documents (including any copies thereof) received from the Company or the
Subsidiaries before, during or after the Due Diligence Period, and (ii) any
documents or materials that Purchaser or its advisers have generated that
contain or disclose information from the documents received from the Company or
the Subsidiaries.  Prior to Closing, except as required in connection with
Kaneb Pipe Line Partners, L.P.'s registration statement filed under the
Securities Act of 1933 and the related offering of partnership units, Purchaser
shall maintain in confidence any information or data received from SPC or the
Subsidiaries in the course of conducting its due diligence, including without
limitation the environmental due diligence





                                       21
<PAGE>   27
provided for in Section 3.1.2, and shall not use the same for any purpose
except in connection with the transaction contemplated by this Agreement,
provided, that the foregoing confidentiality requirement shall remain in effect
after the Closing with respect to the financial statements of the Company and
its Affiliates.  Prior to Closing, and thereafter with respect to the financial
statements of the Company and its Affiliates, except as required in connection
with Kaneb Pipe Line Partners, L.P.'s registration statement filed under the
Securities Act of 1933 and the related offering of partnership units, Purchaser
shall not disclose any such information or data to any third person except to
the extent that (i) such information or data is already in the public domain,
or (ii) such disclosure is compelled or required by subpoena or similar legal
process.

                 3.1.2    Environmental Due Diligence.

                 3.1.2.1  Audits and Surveys. During the Due Diligence Period,
Purchaser may  cause Audits to be conducted by the Purchaser's Consultant, at
its expense, of any of the Real Estate or ROW Real Estate (to the extent such
Audits are permitted under the applicable Right-of-way Agreement).  The scope,
methodology, timing, and conduct of all such Audits shall be subject to the
prior approval of SPC or, with respect to the Savannah, Georgia Real Estate,
SPCT, which approval shall not be unreasonably withheld, except that it shall
not be unreasonable for SPC to withhold its approval based on SPC's reasonable
opinion that such Audit is not permitted under the relevant Right-of-way
Agreement.  All Audits shall be conducted so as to avoid unduly disrupting the
Business.  All such Audits shall be completed within the Due Diligence Period
if, and to the extent that, Purchaser wishes to rely on the results of such
Audits in proposing any adjustment to the Purchase Price under Section 3.1.2.2.
The Purchaser shall cause the Purchaser's Consultant to deliver simultaneously
to SPC copies of all





                                       22
<PAGE>   28
data, reports, surveys, or audits, or drafts thereof that it delivers to
Purchaser with respect to the Acquired Assets or the Business and deliver to
SPC promptly after signing this Agreement copies of all data, reports, surveys,
audits, or drafts thereof delivered to Purchaser with respect to the Acquired
Assets or the Business prior to the signing of this Agreement.

                 3.1.2.2  Purchase Price Adjustment for Certain Remedial Work.

                          (a)     If the Audits prepared by Purchaser's
Consultant under any of the Purchase Agreements disclose that Remedial Work
with respect to the Acquired Assets or the Business or the assets or business
acquired under the PPI Agreement or the Cockpit Agreement is required,
Purchaser may deliver to SPC a written notice describing all such proposed
Remedial Work, and the calculation of the Aggregate Net Remedial Cost with
respect thereto with particularity with respect to the Acquired Assets or the
Business under this Agreement and the assets or business being acquired by
Purchaser under the PPI Agreement and the Cockpit Agreement.  If the Aggregate
Net Remedial Cost for such Remedial Work is in excess of one million dollars
($1,000,000), Purchaser may deliver to SPC an Environmental Adjustment Request
requesting an adjustment in the Aggregate Purchase Price equal to the amount by
which such Aggregate Net Remedial Cost exceeds one million dollars
($1,000,000).

                          (b)     The Net Remedial Cost for Remedial Work with
respect to the Acquired Assets or the Business disclosed pursuant to this
Section 3.1.2.2 shall be aggregated with the Net Remedial Cost for Remedial
Work under Section 3.1.2.2 of the PPI Agreement and Section 3.1.2.2 of the
Cockpit Agreement for purposes of (i) calculating the one million dollar
($1,000,000) threshold described in Section 3.1.2.2 of this Agreement and the
Remaining Threshold, (ii) delivering an Environmental Adjustment Request to SPC
under this Agreement,





                                       23
<PAGE>   29
to PPI under the PPI Agreement or to SIC under the Cockpit Agreement, (iii)
calculating the Aggregate Net Remedial Cost to determine Purchaser's right to
terminate pursuant to Section 10.1(h) of this Agreement, and (iv) calculating
the Aggregate Adjusted Purchase Price to determine SPC's right to terminate
under Section 10.1(c) of this Agreement.

                          (c)     No Environmental Adjustment Request under
this Section 3.1.2.2 may be delivered to SPC more than seventy-five (75) days
from the date of this Agreement. If SPC agrees with the Environmental
Adjustment Request, it shall so notify the Purchaser, and the Aggregate
Purchase Price shall be reduced by the amount by which the Aggregate Net
Remedial Cost exceeds one million dollars ($1,000,000).

                          (d)     If SPC disagrees with the Environmental
Adjustment Request, SPC may at its expense engage SPC's Consultant, who shall
be given copies of all reports and work product of Purchaser's Consultant, and
who shall be free to conduct such additional testing and analysis as it thinks
necessary.  SPC shall cause SPC's Consultant to deliver simultaneously to the
Purchaser copies of all data, reports, surveys or audits, or drafts thereof
that it delivers to SPC with respect to the Acquired Assets or the Business, or
the assets or business being acquired by Purchaser under the PPI Agreement or
the Cockpit Agreement.  As promptly as possible, SPC shall cause SPC's
Consultant to prepare a report, which shall be distributed simultaneously to
SPC, Purchaser, and Purchaser's Consultant, stating (i) whether it agrees that
Remedial Work with respect to the Acquired Assets or the Business or the assets
or business being acquired by Purchaser under the PPI Agreement or the Cockpit
Agreement is required with an Aggregate Net Remedial Cost in excess of one
million dollars ($1,000,000), and (ii) its estimate of the Aggregate Net
Remedial Cost with particularity with respect to the Acquired





                                       24
<PAGE>   30
Assets or the Business under this Agreement and the assets or business being
acquired by Purchaser under the PPI Agreement or the Cockpit Agreement.  If the
lower of the two Aggregate Net Remedial Costs is equal to at least 90% of the
higher of the two, the Aggregate Net Remedial Cost shall be the average of the
two, and the Aggregate Purchase Price shall be reduced by the amount, if any,
by which such average exceeds one million dollars ($1,000,000). If the lower of
the two Aggregate Net Remedial Costs is less than 90% of the higher of the two,
the two Consultants shall jointly engage Groundwater Technologies, Inc. as the
Joint Consultant, at the joint expense of the Company and the Purchaser, who
shall be given copies of all reports and work product of the Purchaser's and
SPC's Consultants, who may conduct such additional testing and analysis as it
considers necessary, and who shall render a report to both parties and their
Consultants stating what the Aggregate Net Remedial Cost, if any, should be,
and that report shall be final and binding on the parties.  To the extent, if
any, that the Aggregate Net Remedial Cost as stated by the Joint Consultant
exceeds one million dollars ($1,000,000), the Aggregate Purchase Price shall be
reduced by the amount of such excess.

                          (e)     To the extent that the Aggregate Net Remedial
Cost is finally determined to exceed one million dollars ($1,000,000) and
therefore result in a reduction of the Aggregate Purchase Price by the amount
of such excess, the reduction of the Aggregate Purchase Price shall be
allocated among SPC under this Agreement, PPI under the PPI Agreement and SIC
under the Cockpit Agreement by subtracting from the Purchase Price in each
respective agreement an amount equal to the Aggregate Purchase Price adjustment
multiplied by a fraction, the numerator of which is the Net Remedial Cost less
one million dollars ($1,000,000) but not less than zero (0) with respect to
this Agreement and the Net Remedial Cost with respect to the





                                       25
<PAGE>   31
PPI Agreement and the Cockpit Agreement and the denominator of which is the
Aggregate Net Remedial Cost.  The foregoing shall be illustrated as follows:

                 3.1.2.3  Purchase Price Adjustment for Other Remedial Work.
Notwithstanding any terms contained in Sections 3.1.2.1 and 3.1.2.2, (i) if
there is a violation of Environmental Law that occurs after the date of this
Agreement and prior to Closing that requires Remedial Work with respect to the
Acquired Assets or the Business that is not completed prior to Closing either
to the reasonable satisfaction of Purchaser or to the satisfaction of the
applicable Governmental Authority, (ii) if after the Due Diligence Period and
prior to Closing a violation of Environmental Law that requires Remedial Work
with respect to the Acquired Assets or the Business is discovered that could
not reasonably have been discovered during the Due Diligence Period by the
Phase I and Phase II environmental audit performed by Versar, Inc. and Handex,
Inc. in 1993, (copies of which have been provided to Purchaser) and such
Remedial Work is not completed prior to Closing either to the reasonable
satisfaction of Purchaser or to the satisfaction of the applicable Governmental
Authority or (iii) if there exists Net Remedial Costs for matters described in
Section 3.1.2.3 of the PPI Agreement or the Cockpit Agreement, then in each
such case Purchaser shall be entitled to an adjustment to the Aggregate
Purchase Price for the Aggregate Net Remedial Cost with respect to matters
described in Section 3.1.2.3 of each of the Purchase Agreements in excess of
the Remaining Threshold with respect to all such Remedial Work remaining to be
completed after Closing, determined in accordance with the procedures set forth
in Section 3.1.2.2 without regard to the 75 day time period for proposing such
adjustment.

                 3.1.2.4  Other Environmental Liabilities.  If, prior to
Closing, Purchaser, SPC or SPCT receives notice of a claim from, or discovers
or receives notice of any facts or circumstances reasonably expected by ICF
Kaiser to give rise to a claim by, any Person or





                                       27
<PAGE>   33
Governmental Authority for liability or obligation (other than for Remedial
Work) related to an alleged violation of Environmental Law with respect to the
Acquired Assets or the Business, it shall promptly notify the other parties
hereto (the "Notice").  Thereafter, SPC and Purchaser shall attempt to agree on
whether a Purchase Price adjustment or other agreeable mechanism is warranted
with respect to such claim.  If the parties are unable to agree, SPC may in its
discretion assume responsibility for such claim and provide Purchaser with an
indemnification against such claim reasonably satisfactory to Purchaser.  If
within thirty (30) days after delivery of the Notice (i) the parties are unable
to agree on an adjustment to the Purchase Price or other agreeable mechanism,
and (ii) SPC fails to assume responsibility for such claim and provide an
indemnification reasonably satisfactory to Purchaser, then Purchaser shall have
the right to terminate this Agreement.

         Section 3.2      Real Property Matters.

                 (a)      Purchaser shall at its expense from the date of this
Agreement through Closing review the status of SPC's (or the applicable
owner's) title to the Real Estate.  As of the date of this Agreement, Purchaser
has received (i) the surveys listed on the attached Schedule 3.2(a) and (ii)
the current title binders listed on the attached Schedule 3.2(a) obtained from
Commonwealth Land Title Insurance Company and Lawyers Title Insurance
Corporation with respect to the Real Estate indicating therein Purchaser as the
proposed insured (with the cost of any update work necessary to cause the
issuance of current title binders to be paid equally by Purchaser and SPC).
The information set forth on such surveys listed on Schedule 3.2(a) and in such
title binders listed on Schedule 3.2(a) (but only to the extent copies of the
documents referenced in such surveys listed on Schedule 3.2(a) and in such
title binders listed on Schedule





                                       28
<PAGE>   34
3.2(a) have been provided to Purchaser), and specifically excluding the matters
described on Schedule 3.2(b), is referred to herein as the "Current Title
Information".  Purchaser shall have the right, at its expense, to cause to be
prepared to its satisfaction current surveys of any or all of the parcels of
Real Estate.

                 (b)      All Real Property Matters disclosed in the Current
Title Information are listed on Schedule 3.2(a) and Purchaser shall not have
the right or the opportunity to raise any other Real Property Matters based on
the Current Title Information.  Purchaser shall have the right for a period of
thirty (30) days after the date of this Agreement to continue to raise as Title
Objections (by written notice to SPC) any or all of the matters described on
Schedule 3.2(b), without regard to the standard set forth in clause (a) of the
definition of Title Objections unless otherwise stated on Schedule 3.2(b).

                 (c)      If Purchaser's review prior to Closing discloses a
Real Property Matter not disclosed in the Current Title Information or in
Schedule 3.2(b), Purchaser shall notify SPC thereof within four (4) Business
Days of discovery.

                 (d)      With respect to the Real Property Matters listed on
Schedule 3.2(a) and any Real Property Matters for which notice is sent to SPC
under clause (c) above, SPC shall at its expense attempt to remedy or cure such
Real Property Matter, provided that, except for payments necessary to release
existing mortgages and any Lien related to said mortgages on Real Estate owned
by SPC or the Subsidiary Partnership, SPC shall have no obligation to spend any

does not cure the Title Objection within thirty (30) days from Purchaser's
notification thereof, the Title Objection shall be an uncured Real Property
Matter for purposes of this Section 3.2.  If SPC is unable to remedy or cure
one or more Real Property Matters within 30 days from Purchaser's notification
thereof, the parties shall attempt in good faith to negotiate an adjustment in
the Purchase Price that will compensate Purchaser for the cost of curing or
remedying the Real Property Matter or for otherwise accepting the Real Estate
as is.  If the parties are unable to agree on an adjustment to the Purchase
Price, and the Real Property Matter is with respect to the Real Estate at Piney
Point, or Jacksonville, this Agreement shall terminate.  If the parties are
unable to agree on an adjustment to the Purchase Price and the Real Property
Matter is with respect to any other parcel of Real Estate, this Agreement shall
terminate with respect to the Terminal located on such parcel or parcels and
all related Acquired Assets and the Purchase Price shall be reduced by the
amount allocated to such Terminal on Schedule 2.5.  Notwithstanding any
provision contained herein that may be construed to the contrary, if (i) any
Lien or restriction with respect to the Real Estate on which the Brunswick
Terminal is located or, if the Partnership Interest is not purchased by
Purchaser, the Real Estate on which the Savannah Terminal is located is not the
result of an act or omission of SPC, and (ii) Purchaser can continue to lease
such Real Estate after the Closing as it is currently being leased by SPC, then
SPC shall have no obligation to remove such Lien or restriction and such Lien
or restriction shall be a Permitted Encumbrance.

         Section 3.3      Consents.  SPC or the Subsidiary Corporation, as
appropriate, shall use reasonable commercial efforts promptly to obtain the
consent, waiver or approval (including without limitation the waiver, release
or termination of rights of first refusal with respect to the





                                       30

to offer employment to any of SPC's employees, on such terms and conditions as
Purchaser may determine, contingent upon and effective at Closing.  SPC shall
terminate all of its salaried and hourly employees of the Business effective at
Closing.  SPC shall be responsible for paying any and all liabilities resulting
from such terminations of such

covenant unless and except to the extent that the affected party is materially
prejudiced or damaged thereby.

         Section 9.4      Inventories and Tank Bottoms.

                 9.4.1  Inventories.  On the Closing Date all of the petroleum
products and other liquids in bulk storage tanks at the Terminals shall be
inventoried, gauged and sampled by representatives of Purchaser and SPC, and
the petroleum products samples shall be promptly tested by an independent
testing laboratory mutually chosen by the parties (at their joint expense) to
verify the specifications of such petroleum products that are owned by SPC's
northern and southern marketing divisions, and by SPC's customers, in
accordance with the procedures set forth in Exhibit 9.4.1.  SPC will be
responsible for (i) any shortages in the inventories (and will be credited with
any overages of inventories other than tank bottoms), and (ii) any petroleum
products that do not meet the owner's specifications for such product, and
shall indemnify and hold Purchaser harmless from liabilities or obligations
resulting therefrom.  Shortages and overages in the inventories (other than
tank bottoms) shall be determined as soon as practicable after Closing.  SPC
shall have the right to resolve any specification matter with the customer,
including disputing customer claims, prior to Purchaser reaching any settlement
therefor.

                 9.4.2.  Wastes.  Representatives of Purchaser and SPC shall
jointly inventory all wastes (including waste water) stored in holding tanks
and separators.  SPC shall reimburse Purchaser for the costs, if any, incurred
in the disposal of such volumes of waste which cannot legally be disposed of
through the existing systems at the terminal locations to the extent the total
aggregate cost for all locations (including the cost for waste disposal from
the Pipeline, as defined under the PPI Agreement) exceeds one hundred thousand
dollars ($100,000) after consideration of amounts, if any, paid by SPC's
customers.  Purchaser shall dispose of said wastes within thirty (30) days of
Closing Date and shall submit copies of invoices and manifests





                                       64
<PAGE>   70
to SPC within sixty (60) days of the Closing Date.  SPC shall pay Purchaser
within forty-five (45) days of receipt of invoices.  Liquid waste as used in
this Section 9.4.2 does not include the tank bottoms portion of the Inventory
covered by Section 9.4.3.

                 9.4.3  Tank Bottoms.  On the Closing Date all tank bottoms
shall be inventoried, gauged and sampled by representatives of the parties, and
shall be tested promptly by an independent testing laboratory mutually chosen
by the parties (at their joint expense), to determine the number of barrels of
merchantable petroleum product contained therein, in accordance with the
procedures set forth in Exhibit 9.4.3. "Merchantable petroleum product" for
this purpose means petroleum product that is free from non-petroleum substances
such as water or rust.  The Purchase Price shall be reduced, dollar-for-dollar,
by the fair market value of the shortfall, if any, between 60,750 barrels of
merchantable petroleum product and the number of barrels of merchantable
petroleum product in the tank bottoms included in the Inventory on the Closing
Date. "Fair market value" for these purposes shall be determined by Platts
price on the Closing Date for 2% No. 6 oil, New York Harbor Posting. To the
extent any monies are due to  Purchaser by virtue of this Section 9.4.3, it
shall be paid by SPC within two Business Days of receipt of the report from the
independent testing laboratory referred to above.

terminated as follows:

                 (a)      by mutual agreement of the parties, at any time;

<PAGE>   71
                 (b)      by either party if the Closing does not occur on or
before  January 1, 1996;

                 (c)      by SPC, if the Aggregate Purchase Price or the
Aggregate Adjusted Purchase Price, as applicable, determined pursuant to the
terms of this Agreement, the Cockpit Agreement and the PPI Agreement, without
regard to Section 12.14, the accounts receivable collection section, of this
Agreement and the PPI Agreement, and without regard to Section 9.4.3 of this
Agreement, totals less than Eighty Million Dollars ($80,000,000), unless
Purchaser is willing in that event to pay the aggregate sum of Eighty Million
Dollars ($80,000,000) for the assets sold under this Agreement, the Cockpit
Agreement and the PPI Agreement.

                 (d)      by SPC at any time after November 30, 1995, if the
conditions to Closing set forth in Article 6 have not been met by that date,
unless the failure to meet such condition is attributable to any fault or
neglect of SPC;

                 (e)      by Purchaser at any time after November 30, 1995, if
the conditions to Closing set forth in Article 5 have not been met by that
date, unless the failure to meet such condition is attributable to any fault or
neglect of Purchaser;

                 (f)      by Purchaser if a Major Loss occurs, provided that
Purchaser gives notice of its intent to terminate within ten (10) Business Days
after it has received notice of such Major Loss;

                 (g)      by Purchaser if it discovers a material breach of any
representation or warranty made by SPC which SPC is unable to cure within
thirty (30) days after having received notice of such breach;





                                       66
<PAGE>   72
                 (h)      by Purchaser if the Aggregate Net Remedial Cost
(whether or not resulting in a Purchase Price adjustment) determined pursuant
to Sections 3.1.2.2 and 3.1.2.3 of this Agreement, the PPI Agreement and the
Cockpit Agreement exceeds six million dollars ($6,000,000);

                 (i)      by SPC if it discovers a material breach of any
representation or warranty made by Purchaser that Purchaser is unable to cure
within thirty (30) days after having received notice of such breach; and

                 (j)      by Purchaser pursuant to Section 3.1.2.4.

         Section 10.2     Effect of Termination.  If this Agreement terminates:

                 (a)      neither party shall have any obligation to the other
party, except that such termination shall be without prejudice to the rights of
any party resulting from the intentional or willful breach or violation of the
representations, warranties, covenants or agreements of the other party under
this Agreement, provided that a failure by a party to close when all of the
conditions to such party's obligation to close have been met shall be deemed to
be an intentional breach of such party's covenants and agreements hereunder.

                 (b)      promptly upon termination for any reason, Purchaser
shall return to SPC or SPCT at Purchaser's expense all documents (including
copies thereof) received from SPC or SPCT prior to, during or after the Due
Diligence Period;

                 (c)      Purchaser shall not offer employment to any of SPC's
employees, without the prior consent of SPC, for two years following the date
of this Agreement; and                                  

                 (d)      the provisions of Section 3.1.1, Section 10.2, and
Sections 12.1, 12.2, 12.3,

12.4, 12.5, 12.6, 12.7, 12.8 and 12.9 shall survive the termination of this
Agreement and continue in full force and effect.

                                INDEMNIFICATION

         Section 11.1     Indemnification by SPC.  Subject to the provisions of
this Article 11, the Company agrees to indemnify, defend, and hold harmless the
Purchaser and its Affiliates, officers, directors, agents, shareholders,
partners, and employees, (each, a "Purchaser Indemnified Party") from and
against any and all liabilities, losses, claims (whether or not successful),
damages, and expenses (including reasonable fees, and disbursements of counsel)
(collectively, "Liabilities") resulting from or arising out of (i) any breach
of any representation or warranty, covenant or agreement of the Company or the
Subsidiary Corporation set forth in this Agreement, (ii) non-compliance with
any applicable transfer or bulk sales law, (iii) obligations or liabilities of
the Company, the Subsidiary Corporation or the Subsidiary Partnership related
to or arising out of acts, events or omissions occurring prior to the Closing
and not expressly assumed by Purchaser hereunder or indemnified against by
Purchaser pursuant to Section 11.7.3, (iv) liabilities or obligations related
to any amendment to a Material Contract or Right-of-Way Agreement or Real
Estate Lease not delivered to Purchaser prior to the date of this Agreement,
unless such amendment is subsequently delivered to and accepted by Purchaser,
or (v) all taxes, assessments or levies relating to the seven (7) parcels of
land described in Exhibit 5.12, provided, however, that the Company shall not
be liable under this





                                       68
<PAGE>   74
Section 11.1 to any Purchaser Indemnified Party  for any amount paid in
settlement of claims without the Company's consent, unless such consent was
requested and unreasonably withheld.

         Section 11.2     Survival of Representations and Warranties.  The
representations and warranties set forth in Sections 7.1, 7.2, 7.3, 7.4, 7.7
and 7.12 shall survive the Closing without limitation of time. The
representations and warranties set forth in Section 7.16 (Environmental

Closing Date. The representations and warranties set forth in Section 7.17
(Taxes) shall survive the Closing and shall expire on a date that is ninety
(90) days following the expiration of the applicable statute of limitations.
All other representations and warranties shall survive the Closing and shall
expire two years after the Closing Date.  Any right of Purchaser to make a
claim against the Company for a breach of any covenant or agreement of the
Company or the Subsidiary Corporation herein shall survive the Closing and
shall expire one hundred eighty (180) days after the date on which the Company
or Subsidiary Corporation was obligated to comply with such covenant or
agreement.  Any claim for breach of a representation and warranty, or covenant
or agreement, must be made by Purchaser by a demand for arbitration to the
Company prior to the expiration of such representation and warranty, or the
right to make a claim for a breach of such covenant or agreement, and any such
claims covered by such demands made by Purchaser to the Company within such
time periods shall survive until resolved.

         Section 11.3     Indemnification by Purchaser.  Purchaser, its
successors and assigns, jointly and severally, agree to indemnify, defend, and
hold harmless the Company, the Subsidiary Corporation and their Affiliates,
officers, directors, shareholders, partners, warrant holders, agents, and
employees, (each, an "SPC Indemnified Party") from and against any and





                                       69
<PAGE>   75
all Liabilities resulting from or arising out of (i) any breach of any
representation, warranty, covenant or agreement of Purchaser or Guarantor set
forth in this Agreement or (ii) obligations or liabilities of the Purchaser
with respect to the Business or the Acquired Assets, including those which may
be imposed upon any SPC Indemnified Party, related to or arising out of acts,
events or omissions occurring after the Closing and not expressly assumed by
any SPC Indemnified Party hereunder and specifically including (but not limited
to) liabilities or obligations arising from the failure of Purchaser to assume
any post-Closing liabilities as required by Section 2.2, provided, however,
that Purchaser shall not be liable under this Section 11.3 to any SPC
Indemnified Party for any amount paid in settlement of claims without
Purchaser's consent unless such consent was requested and unreasonably
withheld, and provided further that the right of the SPC Indemnified Parties to
make a claim for breach of any covenants or agreements of Purchaser herein
shall expire one hundred eighty  (180) days after the date on which the
Purchaser was obligated to comply with the covenant or agreement.

         Section 11.4     Establishment of Escrow Fund.  (a) At Closing, the
Company shall deposit from the proceeds of the Purchase Price the sum of Five
Million Dollars ($5,000,000) (together with interest earned thereon, the
"Escrow Fund") with the Escrow Agent named in the Escrow Agreement attached as
Exhibit 11.4 to this Agreement, to be held in accordance with the terms of the
Escrow Agreement as a fund against which the Purchaser Indemnified Parties can
make indemnification claims under the Purchase Agreements (a "Claim").  Any
Claim shall be addressed first to the Escrow Agent, until the Escrow Fund has
been fully paid out, and then to the Company, PPI or SIC, as applicable,
provided, however, Claims shall only be made to the Company, PPI or SIC, as
applicable, for Claims for which there is no limitation of amount





                                       70
<PAGE>   76
under Section 11.5 of the Purchase Agreements because all other Claims can only
be paid out of the Escrow Fund.  The Escrow Agreement shall provide that (i)
two (2) years after the Closing Date, the Escrow Fund shall be reduced to an
amount equal to the sum of (x) Two Million Dollars ($2,000,000) plus (y) the
aggregate amount of all unresolved Claims against the Escrow Fund, and all
amounts in excess of such amount shall be paid to SPC, provided, however, that
the amount in excess of Two Million Dollars ($2,000,000) retained in the Escrow
Fund for each unresolved Claim shall be released from the Escrow Fund upon
resolution of such Claim, with the agreed amount, if any, of the Claim being
paid to Purchaser and the remainder, if any, of the amount originally retained
in the Escrow Fund for such Claim being paid to SPC (ii) three (3) years after
the Closing Date, the Escrow Fund shall be reduced to an amount equal to the
aggregate amount of all unresolved Claims against the Escrow Fund and amounts
in excess of such amount  shall be paid to SPC, (iii) thereafter, any balance
remaining in the Escrow Fund for each unresolved Claim shall be released from
the Escrow Fund upon resolution of such Claim, with the agreed amount, if any,
of the Claim being paid to Purchaser and the remainder, if any, of the amount
originally retained in the Escrow Fund for such Claim being paid to SPC and
(iv) the Escrow Agreement shall terminate on the later to occur of three (3)
years after the Closing Date and the settlement and satisfaction of all Claims
against the Escrow Fund.

                 (b)      With respect to each Claim made against the Escrow
Fund, SPC and Purchaser shall attempt to reach agreement on the amount, if any,
that should be paid to Purchaser with respect to the Claim, and if an agreement
is reached, SPC and Purchaser shall deliver joint written instructions to the
Escrow Agent regarding the disposition of the Claim and





                                       71
<PAGE>   77
the amount, if any, that should be paid to Purchaser out of the Escrow Fund
with respect to the Claim.  If SPC and Purchaser are unable to reach agreement
regarding the disposition or amount of a Claim, the Claim shall be settled by
arbitration in accordance with the provisions of this Agreement, and the
arbitrator shall, as part of the arbitration award, instruct SPC and Purchaser
to deliver to the Escrow Agent joint written instructions stating the
disposition of the Claim pursuant to the arbitration and the amount, if any,
that should be paid to Purchaser out of the Escrow Fund with respect to the
Claim pursuant to the arbitration award.

                 (c)      To the extent Purchaser is entitled to receive
payment from the Escrow Fund of an amount with respect to any Claim that is not
subject to limitation in amount under Section 11.5 of the Purchase Agreements,
Purchaser may request that the Escrow Agent delay payment from the Escrow Fund
of part or all of such amount until payment of such amount from the Escrow Fund
is requested by Purchaser.  To the extent the amount payable to Purchaser with
respect to any Claim or Claims that are not subject to limitation under Section
11.5 of the Purchase Agreements is in excess of the undisbursed amount of the
Escrow Fund at the time Purchaser requests payment, Purchaser may require
payment directly from SPC, SPCT, SIC or PPI, as applicable, of the amounts not
paid from the Escrow Fund.

         Section 11.5     Limits on Liability.  With the exception of (i)
claims arising under Sections 7.1, 7.2, 7.3, 7.4, 7.7 (but only to the extent
that any claim is based on the specific wording in each of the limited warranty
deeds by which the Real Estate is conveyed) and 7.12 (ii) claims for fines or
penalties imposed by Governmental Authorities, (iii) claims for Liens that are
not Permitted Encumbrances, (iv) claims related to breaches of the agreements
of the Company in Section 9.4, (v) claims for a breach by the Company of the
covenant contained in Section 3.11,





                                       72
<PAGE>   78
(vi) claims under Section 11.1(iv), and (vii) claims under Section 11.1(v), for
which there shall be no limitation of amount, the Company's maximum liability
for Liabilities under the Company's indemnifications under this Agreement,
including without limitation Section 11.7.1.1, shall be the Escrow Fund, and
neither the Company, the Subsidiary Corporation nor any of their Affiliates,
shareholders, warrant holders, partners, officers, directors, agents and
employees shall have any liability for such  Liabilities in excess of the
Escrow Fund.

         Section 11.6     Minimum Claim Amount.  With the exception of (i)
claims arising under Section 11.7.1.1, (ii) claims for fines or penalties
imposed by Governmental Authorities, (iii) claims for Liens that are not
Permitted Encumbrances, (iv) claims related to breaches of the agreements of
the Company in Section 9.4, (v) claims for a breach by the Company of the
covenant contained in Section 3.11, (vi) claims under Section 11.1(iv), and
(vii) claims under Section 11.1(v), for which there shall be no minimum claim,
Purchaser shall not be entitled to assert any claim for indemnification
hereunder until the aggregate of all claims for indemnification under this
Agreement, the PPI Agreement and the Cockpit Agreement collectively exceeds
Seven Hundred and Fifty Thousand Dollars ($750,000) and then only for amounts
in excess of such Seven Hundred and Fifty Thousand Dollars ($750,000).  In each
case in which Purchaser determines that it has a claim for indemnification,
while the aggregate of all claims under this Agreement, the PPI Agreement and
the Cockpit Agreement collectively is less than Seven Hundred and Fifty
Thousand Dollars ($750,000), it shall promptly notify SPC of all such claims in
an amount over $1,000.00, which notice shall describe the claim with
particularity and state the amount of such claim.  If SPC does not challenge
the validity of the claim within thirty (30) days of receiving notice thereof,
it shall be deemed to have been





                                       73

accepted. If SPC disputes the claim, it shall so notify Purchaser, in which
case the parties shall take such steps as are necessary to preserve their
respective positions with respect to such claim and any evidence relating
thereto, so that the claim may be challenged by SPC if the aggregate of all
claims under this Agreement, the PPI Agreement and the Cockpit Agreement
collectively exceeds Seven Hundred and Fifty Thousand Dollars ($750,000).
Notice of all claims in an amount of $1,000.00 or less shall be provided to SPC
promptly after the aggregate of all claims under this Agreement, the PPI
Agreement and the Cockpit Agreement collectively exceed Seven Hundred and Fifty
Thousand Dollars ($750,000).

         Section 11.7     Special Environmental Indemnification and
Post-Closing Covenants by Purchaser.

                 11.7.1.1  To the extent that, prior to the date three years
after the Closing Date, Purchaser discovers and notifies SPC of facts or
circumstances that give rise to Remedial Work (including Remedial Work related
to matters discovered prior to the Closing or disclosed on Schedule 7.16 under
this Agreement or Schedules 7.16 of the PPI Agreement or the Cockpit Agreement)
with respect to the Acquired Assets or the Business or the assets or business
acquired by Purchaser under the PPI Agreement or the Cockpit Agreement (except
for Remedial Work attributable to (i) changes in Environmental Law occurring
after the Closing Date, or (ii) events occurring or actions of Persons other
than SPC, SPCT, SIC or PPI taken after the Closing Date), the Aggregate Net
Remedial Cost for Remedial Work with respect to the Acquired Assets or the
Business being acquired by the Purchaser under this Agreement, the assets or
business being acquired by the Purchaser under the PPI Agreement, or the assets
being acquired by the Purchaser under the Cockpit Agreement shall be paid as
follows:





                                       74
<PAGE>   80
                          (i)     an amount equal to the sum of (X) One Million
Dollars ($1,000,000) and (Y) any reduction in the Aggregate Purchase Price
pursuant to Section 3.1.2.2 or 3.1.2.3 shall be paid by Purchaser;

                          (ii)    the next Two Million Five Hundred Thousand
Dollars ($2,500,000) of such Aggregate Net Remedial Costs shall be paid, as
incurred pari passu,  eighty  percent (80%)  by SPC (and Purchaser shall make a
claim on the Escrow Fund therefor) and twenty percent (20%) by Purchaser; and

                          (iii)   thereafter Purchaser shall pay all additional
amounts of such Aggregate Net Remedial Costs related to the Acquired Assets or
the Business being acquired by the Purchaser under this Agreement, the assets
or business being acquired by the Purchaser under the PPI Agreement, or the
assets being acquired by the Purchaser under the Cockpit Agreement.

         Notwithstanding the preceding portions of this Section 11.7.1.1,
Purchaser shall not be liable for or be required to pay any Aggregate Net
Remedial Costs resulting from or arising out of any action or omission after
Closing of any SPC Indemnified Party, any SIC Indemnified Party (as defined in
the Cockpit Agreement) or any PPI Indemnified Party (as defined in the PPI
Agreement) that constitutes or causes a violation of Environmental Law with
respect to the Business or the Acquired Assets being acquired by the Purchaser
under this Agreement, the assets or business being acquired by the Purchaser
under the PPI Agreement, or the assets being acquired by the Purchaser under
the Cockpit Agreement or gives rise to the need to perform Remedial Work with
respect thereto, unless otherwise agreed to in writing by Purchaser.

                 11.7.1.2  Purchaser shall not alter or change the scope or
methodology of Remedial Work described on Schedule 7.16 except as required by
Applicable Law or as approved by the Company, which approval shall not be
unreasonably withheld, provided, however, that an objection shall not be deemed
unreasonable solely because it is based on an increase in the cost for
performing such Remedial Work.  For so long as SPC has any liability to
Purchaser under Section 11.7.1.1, Purchaser shall use commercially reasonable
efforts to perform and complete all such required Remedial Work and shall keep
SPC informed of the progress of such Remedial Work.  In addition, before
undertaking any such Remedial Work  Purchaser shall notify SPC of the scope and
methodology of such Remedial Work, sufficiently in advance (except as emergency
conditions may require otherwise) to permit SPC to comment on such scope and
methodology.  Recognizing that the final decision on scope and methodology
rests with Purchaser, Purchaser shall nonetheless make a good faith effort to
reach agreement with SPC regarding such scope and methodology, recognizing
SPC's financial interest therein.  Purchaser shall provide SPC with copies of
all plans, reports, and correspondence submitted to any Governmental Authority
with respect to such Remedial Work.  Purchaser will not agree to any such
Remedial Work or other actions that commit or bind SPC (beyond the payment of
money hereunder) without the prior consent of SPC. Purchaser will provide SPC
with copies of all invoices rendered by Persons actually performing such
Remedial Work, and SPC shall be deemed to have accepted the validity and
reasonableness of such invoices if it does not notify Purchaser to the contrary
within ten (10) Business Days of receiving the same.

                 11.7.2  (a) Purchaser and Guarantor acknowledge that (i)
Purchaser has reviewed copies of all documents and other materials related to
environmental matters with respect to the





                                       76
<PAGE>   82
Acquired Assets and the Business that were provided by the Company or SPCT,
(ii) the Company and SPCT have specifically bargained for relief, as more
particularly described herein, from post-Closing liability resulting from
violations of Environmental Law or the performance of Remedial Work with
respect to the Acquired Assets or the Business, and (iii) the Purchase Price
and Adjusted Purchase Price, as the case may be, reflect Purchaser's
willingness to accept liability ( and Guarantor's willingness to guarantee
Purchaser's obligation to accept such liability) with respect to such matters
as more fully described below.

                          (b)     Purchaser has agreed to assume, and Guarantor
has agreed to guarantee the obligation of Purchaser to assume, as of the
Closing all obligations and liabilities resulting from or arising out of any
actual or alleged violation of Environmental Law related to the Acquired Assets
or the Business, regardless of when such violation was supposed to have
occurred, or the performance of Remedial Work with respect to the Acquired
Assets or the Business, except for (i) fines and penalties imposed by any
Governmental Authority relating to violations of Environmental Law that
occurred prior to Closing with respect to the Acquired Assets or the Business,
(ii) payments to be made by SPC pursuant to Section 11.7.1.1, (iii) obligations
or liabilities that result from or arise out of any act or omission after the
Closing of any SPC Indemnified Party that constitutes or causes a violation of
Environmental Law with respect to the Business or the Acquired Assets or gives
rise to the need to perform Remedial Work with respect thereto, unless
otherwise agreed to in writing by Purchaser, and (iv) claims for a breach of
the representations and warranties set forth in Section 7.16 to the extent
Purchaser is entitled to indemnity under this Article 11.





                                       77
<PAGE>   83
                          (c)     For the avoidance of any doubt, Purchaser,
Guarantor, SPC and SPCT confirm their agreement that neither SPC nor SPCT shall
have any obligation or liability post-Closing resulting from or arising out of
any actual or alleged violation of Environmental Law related to the Acquired
Assets or the Business, regardless of when such violation was supposed to have
occurred, or the performance of Remedial Work with respect to the Acquired
Assets or the Business, except (i) fines and penalties imposed by any
Governmental Authority relating to violations of Environmental Law that
occurred prior to Closing with respect to the Acquired Assets or the Business,
(ii) payments to be made by SPC pursuant to Section 11.7.1.1, (iii) obligations
or liabilities that result from or arise out of any act or omission after
Closing of any SPC Indemnified Party that constitutes or causes a violation of
Environmental Law with respect to the Business or the Acquired Assets or gives
rise to the need to perform Remedial Work with respect thereto, unless
otherwise agreed to in writing by Purchaser, and (iv) claims for a breach of
the representations and warranties set forth in Section 7.16 to the extent
Purchaser is entitled to indemnity under this Article 11.

                 11.7.3  Purchaser, its successors and assigns, jointly and
severally, agree to indemnify, defend, and hold harmless each SPC Indemnified
Party  from and against any and all Liabilities resulting from or arising out
of any actual or alleged violation of Environmental Law related to the Acquired
Assets or the Business, regardless of when such violation was supposed to have
occurred, or the performance of Remedial Work with respect to the Acquired
Assets or the Business, except for (i) fines and penalties imposed by any
Governmental Authority relating to violations of Environmental Law that
occurred prior to Closing with respect to the Acquired Assets or the Business,
(ii) payments to be made by SPC pursuant to Section





                                       78
<PAGE>   84
11.7.1.1, (iii) obligations or liabilities that result from or arise out of any
act or omission after Closing of any SPC Indemnified Party that constitutes or
causes a violation of Environmental Law with respect to the Business or the
Acquired Assets or gives rise to the need to perform Remedial Work with respect
thereto, unless otherwise agreed to in writing by Purchaser, and (iv) claims
for a breach of the representations and warranties set forth in Section 7.16 to
the extent Purchaser is entitled to indemnity under this Article 11.
Notwithstanding the preceding provisions of this Section 11.7.3, Purchaser
shall not be liable under this Section 11.7.3 to any SPC Indemnified Party for
any amount paid in settlement without Purchaser's consent unless such consent
was requested and unreasonably withheld.

                 11.7.4  Purchaser shall, for a period of five (5) years after
Closing, notify the Company promptly of any claim made by any Governmental
Authority or by any Person that there has been a violation of Environmental Law
in connection with the Business or the Acquired Assets, or occurring on or from
the Real Estate or the ROW Real Estate, and shall thereafter keep the Company
informed of actions being taken or the conduct of proceedings with respect to
such claim, provided that once it has been reasonably determined to the
satisfaction of SPC that the amount required to resolve such claim (whether by
performing Remedial Work or otherwise) is less than $250,000, Purchaser shall
no longer be obligated to provide SPC with information about such claim.

         Section 11.8     Notification; Counsel.  Each Indemnified Party under
this Article 11 will, promptly after the receipt of notice of the commencement
of any action, investigation, claim or other proceeding against such
Indemnified Party in respect of which indemnity may be sought  under this
Article 11, notify the Company and SPCT or the Purchaser, as the case may be,
in





                                       79
<PAGE>   85
writing of the commencement thereof. The failure of any Indemnified Party to
give such notice shall not relieve the indemnifying  party from any liability
which it may have to such Indemnified Party unless, and only to the extent
that, such omission materially adversely affects the indemnifying party's
ability to defend in such action, claim or other proceeding. In case any such
action, claim or other proceeding shall be brought against any Indemnified
Party and it shall notify the indemnifying party of the commencement thereof,
and, except as otherwise stated herein, the indemnifying party shall be
entitled to assume the defense thereof at its own expense, with counsel
satisfactory to such Indemnified Party.  Notwithstanding the foregoing, in any
action, claim or proceeding in which both an indemnifying party, on the one
hand, and an Indemnified Party, on the other hand, is, or is reasonably likely
to become, a party, such Indemnified Party shall have the right to employ
separate counsel at the indemnifying party's expense and to control its own
defense of such action, claim or proceeding if, in the reasonable opinion of
counsel to such Indemnified Party, a conflict or potential conflict exists
between the indemnifying party, on the one hand, and such Indemnified Party, on
the other hand, that would make such separate representation advisable. In any
event, the Indemnified Party will reasonably cooperate with the indemnifying
party in any defense undertaken by an indemnifying party.

         Section 11.9     Net Worth Covenant.  (a) SPC agrees that for a period
of five (5) years after Closing it will maintain a net worth (assets minus
liabilities on a GAAP basis balance sheet adding back those liabilities
attributable to the above market portion of payment obligations under the
throughput agreements described in Section 5.7 and also the deferred income
taxes, if any, attributable to the proposed like kind exchange completed in
accordance with Section 3.8) in excess of $20,000,000.  During the five (5)
year period, SPC shall provide to Purchaser, as





                                       80
<PAGE>   86
soon as they are available, but in no event more than sixty (60) days after
year end, annual calendar year GAAP basis financial statements (and more
frequent financial statements if requested by Purchaser) and such other
information as is reasonably necessary for Purchaser to confirm compliance with
the net worth covenant described in this Section 11.9;

         (b) SPC may (so long as SIC meets the net worth requirement set forth
in the next sentence), at any time during the five (5) year period, provide
Purchaser with a guaranty, in the form attached hereto as Exhibit 11.9, from
SIC in the amount of  $20,000,000 and upon the delivery of such guaranty to
Purchaser the covenant contained in Section 11.9(a) shall be null and void.
Purchaser shall accept the SIC guaranty so long as SIC has, and agrees to
maintain for the remainder of the five (5) year period, a net worth equal to or
greater than $20,000,000.  If SIC provides the guaranty described above, SPC
shall not thereafter be required to comply with the requirements of Section
11.9(a), and the guaranty shall state that SIC shall thereafter provide
Purchaser, at the times the SPC financial statements    would have been
required under the preceding subsection (a), of this Section 11.9, a letter
from SIC's independent auditors stating that SIC's net worth (on a GAAP balance
sheet basis adding back the deferred income taxes, if any, attributable to the
proposed like-kind exchange completed in accordance with Section 3.8 and those
liabilities attributable to the above market portion of payment obligations
under the throughput agreements described in Section 5.7) is at least
$20,000,000.

                 (a)      No failure or delay on the part of any party hereto

<PAGE>   91
a draft of such announcement to the other party and shall give the other party

         Section 12.11.A  Post-Closing Access to Books and Records by
Purchaser.  For a period of five (5) years after the Closing Date, subject to
reasonable advance notice of time and purpose and to the execution by Purchaser
of reasonable confidentiality undertakings, Purchaser and its authorized
representatives may at Purchaser's expense have reasonable access during normal
business hours to the books and records related to the Business or Acquired
Assets that are not included in the Acquired Assets and SPC will furnish to
Purchaser such additional information and will cooperate with Purchaser in such
other respects as Purchaser may reasonably request, to the extent that such
access and disclosure of such information and cooperation are required by
Purchaser for financial 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 Authorities, so long as such
disclosure, access, and cooperation do not violate the terms of any agreement
to which SPC is bound or any Applicable Law or result in the loss of any
attorney-client or work product privilege.  SPC will use reasonable efforts in
accordance with SPC's normal record maintenance procedures to keep and maintain
all such books and records for a period of five (5) years from the Closing or
longer as may be required by statute,





                                       86
<PAGE>   92
except that notwithstanding any requirements of SPC's normal record maintenance
procedures, SPC shall not destroy books and records related to the Business or
Acquired Assets during such five (5) year period.  From and after such five (5)
year period, SPC shall give Purchaser sixty (60) days prior notice before
destroying any of such books and records, and Purchaser may at any time during
such sixty (60) days take possession, at Purchaser's cost, of such books and
records, provided that if Purchaser does not take possession of any of such
books and records during such sixty (60) days, SPC shall be free thereafter to
dispose of such books and records.

         Section 12.11.B  Post-Closing Access to Books and Records by SPC.  For
a period of five (5) years after the Closing Date, subject to reasonable
advance notice of time and purpose and to the execution by SPC of reasonable
confidentiality undertakings, SPC and its authorized representatives may at
SPC's expense have reasonable access during normal  business hours to the books
and records related to the Business or Acquired Assets that are included in the
Acquired Assets and Purchaser will furnish to SPC such additional information
and will cooperate with SPC in such other respects as SPC may reasonably
request, to the extent that such access and disclosure of such information and
cooperation are required by SPC for financial 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
Authorities, so long as such disclosure, access, and cooperation do not violate
the terms of any agreement to which Purchaser is bound or any Applicable Law or
result in the loss of any attorney-client or work product privilege.  Purchaser
will use reasonable efforts in accordance with Purchaser's normal record
maintenance procedures to keep and maintain all such books and records for a
period of five (5) years from the Closing or longer as may be required by
statute, except that





                                       87
<PAGE>   93
notwithstanding any requirements of Purchaser's normal record maintenance
procedures, Purchaser shall not destroy books and records transferred to
Purchaser hereunder during such five (5) year period.  From and after such five
(5) year period, Purchaser shall give SPC sixty (60) days prior notice before
destroying any of such books and records, and SPC may at any time during such
sixty days take possession, at SPC's cost, of such books and records, provided
that if SPC does not take possession of any of such books and records during
such sixty days, Purchaser shall be free thereafter to dispose of such books
and records.

         Section 12.12    Treatment of Purchase Agreements.  Notwithstanding
any provision contained in any of the Purchase Agreements that may be construed
to the contrary, (i) the aggregate Liabilities of SPC, SPCT, PPI and SIC under
the Purchase Agreements that are subject to maximum liability limits pursuant

                          authorities relating to the Business, issued by any
                          Governmental Authority and any applications for such
                          items.

         Section 2.2      Assumption of Liabilities.  (a) Purchaser shall
assume at Closing:

                 (i)  obligations of PPI under the Contracts and Right-of-way
Agreements attributable to periods of time commencing with the Closing,
provided, however, that (A) with respect to Material Contracts and Right-of-way
Agreements, Purchaser assumes such obligations only for Material Contracts
listed on Schedule 2.1(d) and Right-of-way Agreements listed on Schedule 2.1(b)
and in each case only to the extent true and correct copies thereof and all
amendments thereto have either been delivered to Purchaser as of the date
hereof, or are delivered to and consented to by Purchaser after the date
hereof, provided, however, that to the extent that a copy of an immaterial
amendment to such Material Contract or such Right-of-way Agreement has not been
provided to Purchaser as of the date hereof, Purchaser shall assume such
obligations for such Material Contract or such Right-of-way Agreement without
regard to the amendment not delivered to Purchaser and, in such event, PPI
shall be responsible for all Liabilities of Purchaser with respect to the
amendment not delivered to Purchaser without regard to the limits set forth in
Section 11.5 and (B) Purchaser specifically does not assume, and shall not be
treated as having assumed, any liability or obligation under any Material
Contract or Right-of-way Agreement to the extent such liability or obligation
relates to or arises out of a breach of such Contract or Right-of-way Agreement
that occurs prior to the Closing (provided that liability and obligation for
Purchaser's continuing breaches of such Contracts or such Right-of-way
Agreements after Closing and liability and obligation for breaches of such
Contracts or





                                      11
<PAGE>   17
Right-of-way Agreements commenced by Purchaser after Closing shall be the
responsibility of Purchaser); and

                 (ii)  except as expressly provided for otherwise herein and in
accordance with the provisions of Section 11.7, any amounts payable to perform
Remedial Work with respect to the Pipeline Assets or the Business, regardless
of when the events giving rise to the obligation to perform such Remedial Work
are alleged to have occurred.

                 The obligations assumed by Purchaser pursuant to subsection
(a) of this Section 2.2 are referred to herein collectively as the "Assumed
Liabilities".

         (b)  Purchaser shall not assume any liabilities or obligations of PPI
not specifically assumed under subsection (a) of this Section 2.2, except to
the extent that Purchaser's covenants in Section 11.7 constitute an assumption
of such liabilities or obligations.  Nothing herein shall be deemed to
contravene the Purchaser's indemnification of PPI in Sections 11.3 and 11.7,
which shall remain in full force and effect.  Without in any way limiting the
foregoing, the parties agree that the Purchaser does not and will not assume
the sponsorship of, or the responsibility for contributions to, or any
liability in connection with, any employee pension benefit plan, any employee
welfare benefit plan, or other employee benefit agreement or arrangement
maintained or adopted by PPI for its employee, former employees, retirees,
their beneficiaries or any other Person.  In addition and not as a limitation
of the foregoing covenant, the parties agree that PPI shall be liable for any
continuation coverage (including any penalties, excise taxes or interest
resulting from the failure to provide continuation coverage) required by
Section 4980B of the Code due to qualifying events which occur on or before the
Closing Date.





                                      12
<PAGE>   18
Notwithstanding the foregoing, Purchaser shall provide health and medical
benefits under its then existing plans, effective as of the date of hire, if
the PPI employee is hired by Purchaser.

         Section 2.3      Payment of Purchase Price.  The consideration for the
sale of the Pipeline Assets shall be the Purchase Price and the assumption by
the Purchaser of the Assumed Liabilities.

                 2.3.1    Purchase Price. At the Closing, Purchaser shall pay
for the Pipeline Assets the sum of Four Million Two Hundred Thousand
($4,200,000) (the "Purchase Price"), or the Adjusted Purchase Price, as the
case may be.  Notwithstanding any provision contained herein that may be
construed to the contrary, any adjustment to the Purchase Price pursuant to the
terms of this Agreement (other than Section 12.14) shall be calculated as part
of the Aggregate Adjusted Purchase Price for purposes of determining SPC's
right to terminate the Asset Purchase Agreement pursuant to Section 10.1(c)
therein.

                 2.3.2    Intentionally Omitted.

         Section 2.4      Allocation of Purchase Price Amongst Pipeline Assets.
The Purchase Price shall be allocated amongst the Pipeline Assets in accordance
with the fair market values set forth on Schedule 2.4. Neither party shall take
any position inconsistent with Schedule 2.4 in any filing with the Internal
Revenue Service or for any other purpose.

         Section 2.5      Intentionally Omitted.

         Section 2.6      Payment of Taxes and Closing Costs.  Purchaser shall
be responsible for and shall pay any and all state sales taxes arising in
connection with the sale of the Pipeline Assets.  All closing costs in
connection with the transfer of the rights under the Right-of-way





                                      13
<PAGE>   19
Agreements, including transfer taxes, if any, and recording fees, shall be paid
equally by PPI and Purchaser.

         Section 2.7      Risk of Loss.

                 (a)      The risk of loss of the Pipeline Assets shall pass to
Purchaser at Closing.  If there is any loss, damage, breakdown, or casualty to
any of the Pipeline Assets prior to Closing that does not constitute either (i)
a loss, damage, breakdown, or casualty that has been repaired or replaced to
the reasonable satisfaction of Purchaser, or (ii) a loss, damage, breakdown, or
casualty fully covered by insurance proceeds which have been assigned to
Purchaser and insurance retentions paid by PPI to Purchaser, the Purchase Price
shall be reduced by the cost to repair or replace such assets, estimated if
necessary.  If there is reasonable doubt whether a loss, damage, breakdown, or
casualty is fully covered by insurance and the payment of insurance retentions
by PPI, Purchaser may reduce the Purchase Price by the cost of repairing or
replacing such assets, in which case PPI shall not assign the insurance
proceeds or pay any insurance retentions to Purchaser.  The cost of repairing
or replacing such assets shall be such cost or estimated cost as is agreed upon
between the parties.

                 (b)      Notwithstanding the above provisions of this Section
2.7, if any repair or replacement is reasonably expected to cause the Average
Monthly Revenue to decrease by five percent (5%) or more during the month
immediately  following Closing, Purchaser may, in lieu of accepting insurance
proceeds and any insurance retentions or a reduction in the Purchase Price,
delay the Closing until PPI has completed such repair or replacement to the
reasonable satisfaction of Purchaser, provided, however, that if Purchaser
elects to delay the Closing, SPC and SIC, both, but not separately, may elect
to delay the Closing contemplated under the Asset





                                      14
<PAGE>   20
Purchase Agreement and the Closing contemplated under the Cockpit Agreement
until such time as the closings under the Purchase Agreements can occur
simultaneously.  If the Purchaser elects to delay the Closing pursuant to the
preceding sentence, then (unless PPI is entitled to and elects to terminate
this Agreement pursuant to Article 10), PPI shall promptly and diligently cause
such repair or replacement to be completed to the reasonable satisfaction of
Purchaser.

                            MATTERS PRIOR TO CLOSING

         Section 3.1      Due Diligence.

                 3.1.1    Examination of Records and Assets. During the Due
Diligence Period, (i) Purchaser and its agents may examine the Pipeline Assets
and the Business, and such books, records, files, and documents of the Company
that relate to the Business or the Pipeline Assets, (ii) the Company shall make
available to Purchaser and its agents for review all information concerning the
Pipeline Assets or the Business which they may request, and (iii) the Company
will make available to Purchaser the officers and the employee of the Company
to answer questions and to discuss the Company and its Business, all in a
manner that does not unduly disrupt the Business. If the Closing does not
occur, Purchaser shall promptly return to the Company, at Purchaser's expense,
(i) all documents (including any copies thereof) received from the Company
before, during or after the Due Diligence Period, and (ii) any documents or
materials that Purchaser or its advisers have generated that contain or
disclose information from the documents received from the Company.  Prior to
Closing, except as required in connection with Kaneb Pipe Line Partners, L.P.'s
registration statement filed under the Securities Act of





                                      15
<PAGE>   21
1933 and the related offering of partnership units, Purchaser shall maintain in
confidence any information or data received from PPI in the course of
conducting its due diligence, including without limitation the environmental
due diligence provided for in Section 3.1.2, and shall not use the same for any
purpose except in connection with the transaction contemplated by this
Agreement, provided, that the foregoing confidentiality requirement shall
remain in effect after the Closing with respect to the financial statements of
the Company and its Affiliates.  Prior to Closing, and thereafter with respect
to the financial statements of the Company and its Affiliates, except as
required in connection with Kaneb Pipe Line Partners, L.P.'s registration
statement filed under the Securities Act of 1933 and the related offering of
partnership units, Purchaser shall not disclose any such information or data to
any third person except to the extent that (i) such information or data is
already in the public domain, or (ii) such disclosure is compelled or required
by subpoena or similar legal process.

                 3.1.2    Environmental Due Diligence.

                 3.1.2.1  Audits and Surveys. During the Due Diligence Period,
Purchaser may  cause Audits to be conducted by the Purchaser's Consultant, at
its expense, of any of the Pipeline Assets and ROW Real Estate (to the extent
such Audits are permitted under the applicable Right-of-way Agreement).  The
scope, methodology, timing, and conduct of all such Audits shall be subject to
the prior approval of PPI which approval shall not be unreasonably withheld,
except that it shall not be unreasonable for PPI to withhold its approval based
on PPI's reasonable opinion that such Audit is not permitted under the relevant
Right-of-way Agreement.  All Audits shall be conducted so as to avoid unduly
disrupting the Business.  All such Audits shall be completed within the Due
Diligence Period if, and to the extent that, Purchaser wishes





                                      16
<PAGE>   22
to rely on the results of such Audits in proposing any adjustment to the
Purchase Price pursuant to Section 3.1.2.2.  The Purchaser shall cause the
Purchaser's Consultant to deliver simultaneously to PPI copies of all data,
reports, surveys, or audits, or drafts thereof that it delivers to Purchaser
with respect to the Business or the Pipeline Assets and deliver to PPI promptly
after signing this Agreement copies of all data, reports, surveys, audits, or
drafts thereof delivered to Purchaser with respect to the Business or the
Pipeline Assets prior to the signing of this Agreement.

                 3.1.2.2  Purchase Price Adjustment for Certain Remedial Work.

                          (a)     If the Audits prepared by Purchaser's
Consultant disclose that Remedial Work is required with respect to the Pipeline
Assets or the Business, then Purchaser shall record and track such Remedial
Work with any Remedial Work disclosed pursuant to Section 3.1.2.2 of the Asset
Purchase Agreement and Section 3.1.2.2 of the Cockpit Agreement and Purchaser
may deliver to PPI and SPC an Environmental Adjustment Request to request an
adjustment to the Purchase Price subject to this subsection (a) and subsections
(b), (c) and (d) below.  The Net Remedial Cost for Remedial Work with respect
to the Pipeline Assets or the Business disclosed pursuant to this Section
3.1.2.2 shall be aggregated with the Net Remedial Cost for Remedial Work under
Section 3.1.2.2 of the Asset Purchase Agreement and Section 3.1.2.2 of the
Cockpit Agreement for purposes of (i) calculating the one million dollar
($1,000,000) threshold described in Section 3.1.2.2 of the Asset Purchase
Agreement and the Remaining Threshold, (ii) delivering an Environmental
Adjustment Request to SPC and PPI, (iii) calculating the Net Remedial Cost to
determine Purchaser's right to terminate pursuant to Section 10.1(h) of the
Asset Purchase Agreement, and (iv) calculating the Aggregate Adjusted Purchase





                                      17
<PAGE>   23
Price to determine SPC's right to terminate under Section 10.1(c) of the Asset
Purchase Agreement.

                          (b)     The time limitations and procedures for (i)
delivering an Environmental Adjustment Request, and (ii) determining the Net
Remedial Cost for Remedial Work required with respect to the Pipeline Assets or
the Business set forth in Section 3.1.2.2 of the Asset Purchase Agreement shall
apply hereunder.

                          (c)     Any Environmental Adjustment Request that
includes a description of Remedial Work required with respect to the Pipeline
Assets or the Business shall be delivered to PPI and SPC.

                          (d)     To the extent, if any, that the Aggregate Net
Remedial Cost under the Purchase Agreements exceeds one million dollars
($1,000,000) and any of the excess amount of such Aggregate Net Remedial Cost
is attributable to the Pipeline Assets or the Business as determined in
accordance with the procedures set forth in Section 3.1.2.2(e) of the Asset
Purchase Agreement, then the Purchase Price shall be reduced by the amount of
such excess in accordance with Section 3.1.2.2 of the Asset Purchase Agreement.

                 3.1.2.3  Purchase Price Adjustment for Other Remedial Work.
Notwithstanding any terms contained in Sections 3.1.2.1 and 3.1.2.2, (i) if
there is a violation of Environmental Law that occurs after the date of this
Agreement and prior to Closing that requires Remedial Work with respect to the
Pipeline Assets or the Business that is not completed prior to Closing either
to the reasonable satisfaction of Purchaser or to the satisfaction of the
applicable Governmental Authority, or (ii) if after the Due Diligence Period
and prior to Closing a violation of Environmental Law that requires Remedial
Work with respect to the Pipeline





                                      18
<PAGE>   24
Assets or the Business is discovered that could not reasonably have been
discovered during the Due Diligence Period by a Phase I and Phase II
environmental audit and such Remedial Work is not completed prior to Closing
either to the reasonable satisfaction of Purchaser or to the satisfaction of
the applicable Governmental Authority, then in each such case Purchaser shall
be entitled to an adjustment to the Aggregate Purchase Price determined in
accordance with the procedures set forth in Sections 3.1.2.2 and 3.1.2.3 of the
Asset Purchase Agreement without regard to the 75 day time period for proposing
such adjustment.

                 3.1.2.4  Other Environmental Liabilities.  If, prior to
Closing, Purchaser or PPI receives notice of a claim from, or discovers, or
receives notice of any facts or circumstances reasonably expected by ICF Kaiser
to give rise to a claim by, any Person or Governmental Authority for liability
or obligation (other than for Remedial Work) related to an alleged violation of
Environmental Law with respect to the Pipeline Assets or the Business, it shall
promptly notify the other parties hereto (the "Notice").  Thereafter, PPI and
Purchaser shall attempt to agree on whether a Purchase Price adjustment or
other agreeable mechanism is warranted with respect to such claim.  If the
parties are unable to agree, PPI may in its discretion assume responsibility
for such claim and provide Purchaser with an indemnification against such claim
reasonably satisfactory to Purchaser.  If within thirty (30) days after the
Notice (i) the parties are unable to agree on an adjustment to the Purchase
Price or other agreeable mechanism, and (ii) PPI fails to assume responsibility
for such claim and provide an indemnification reasonably satisfactory to
Purchaser, then Purchaser shall have the right to terminate this Agreement.

         Section 3.2      Intentionally Omitted.

or approval is required to effect an assignment of any of the Material
Contracts or Right-of-way Agreements, or to transfer any of the Pipeline Assets
to Purchaser, or otherwise in connection with this transaction, and, where
appropriate, to effect a novation of such Material Contracts or Right-of-way
Agreements.  Purchaser shall cooperate with PPI in obtaining such items as
reasonably requested to do so by PPI.

                 (b)      Purchaser acknowledges that (i) the Tariff will not
be transferred to Purchaser and (ii) Purchaser must apply for its own tariff
and operating agreement to transport petroleum products to, and store petroleum
products at, Andrews AFB after Closing.

         Section 3.4      Hart-Scott-Rodino.  Purchaser and PPI shall each
comply with the notification, waiting period and other requirements of the HSR
Act.  Each party shall take reasonable steps to provide information to and
otherwise cooperate with the other parties for the purposes of making required
filings under the HSR Act.

         Section 3.5      Purchaser's Licenses, Permits.  Purchaser shall (i)
exercise reasonable commercial efforts promptly to obtain all licenses and
permits required by Purchaser to purchase the Pipeline Assets, and (ii) use

operating agreement to transport petroleum products to, and store petroleum
products at, Andrews AFB with a tariff rate of at least $.95 per Bbl. and
containing substantially similar terms as the most recently effective Tariff.

                 (a)      PPI shall provide Purchaser with the name, address
and base salary of its employee, and provide Purchaser with the opportunity to
conduct a pre-employment interview with the employee.  Purchaser may but shall
not be obligated to offer employment to the PPI employee, on such terms and
conditions as Purchaser may determine, contingent upon and effective at
Closing.  PPI shall terminate the employee effective at Closing.  PPI shall be
responsible for paying any and all liabilities resulting from such termination
(including, but not limited to, any liabilities under the Workers Adjustment
and Retraining Notification Act, if applicable) and will indemnify and hold
harmless Purchaser therefrom.

                 (b)      PPI and SPC will terminate the Dockman Services
Agreement, the Consulting Agreement and the Emergency Spill Response Agreement
effective on the Closing Date.

         Section 3.7      Notification.  Each party shall promptly notify the
other parties if it has Knowledge of (i) any information indicating that any
representation or warranty of any other party is or may be untrue in any
material respect, (ii) any covenant to be performed by such other party that is
not being performed, or (iii) any circumstance that would impede or interfere
with the Closing, except that no party shall be liable for a breach of this
covenant unless and except to the extent that the affected party is materially
prejudiced or damaged thereby.

         Section 3.8      Deferred Like-Kind Exchange.  Upon the request of

action as may be commercially reasonable to consummate the transactions
contemplated by this Agreement.

                                   ARTICLE 4

                   OPERATION OF THE BUSINESS PRIOR TO CLOSING

         Section 4.1      Ordinary Course.  (a) Between the date of this
Agreement and the Closing, PPI shall (i) carry on the Business diligently in

no event later than

                                      30
<PAGE>   36
the results of operations of the Business as of the respective dates or for the

         Section 7.10     Employee Plans.

                 (a)      Types of Employee Plans.  Except as set forth in
Schedule 7.10, the Company does not maintain or contribute to any "employee
pension benefit plan" or any "employee welfare benefit plan" as such terms are
defined in Section 3(2) and Section 3(1), respectively, of the ERISA nor, since
April 28, 1980, has the Company participated in or contributed to a
"multi-employer plan" as such term is defined in Section 3(37) of ERISA.

respective directors, officers, employees or agents, nor any "party in
interest" or "disqualified person", as such terms are defined in Section 3 of
ERISA and Section 4975 of the Code, has, with respect to any employee plan
identified in Section 7.10(a) hereof ("Employee Plan") engaged in or been a

<PAGE>   37

requirements prescribed by any and all statutes, orders, or governmental rules
or regulations currently in effect with respect to all Employee Plans,

respect of, and has no knowledge of any material default or violation by any
other party to, any of the Employee Plans.

                 (d)      Qualifications.  To the Company's Knowledge, each
Employee Plan intended to qualify under Section 401(a) of the Code has
heretofore been determined by the Internal Revenue Service to so qualify, and
the trusts created thereunder have heretofore been determined to be exempt from
tax under the provisions of Section 501(a) of the Code, and nothing has since
occurred which may reasonably be expected to cause the loss of such
qualification or exemption.

                 (e)      No Carryover Liability.  The consummation of this
Agreement (and the employment by the Purchaser of PPI's former employee) will
not result in any carryover liability to the Purchaser for taxes, penalties,
interest or any other claims resulting from any Employee Plan, or other
employee benefit agreement or arrangement.  In addition, PPI makes the
following representations (a) as to employee pension benefit plans of the
Company: (1) no Company has become liable to the PBGC under Sections 4062,

the Company have been operated in compliance with Section 4980B(f) of the Code.

executed and delivered by Purchaser and Guarantor, and constitutes the legal,
valid and binding obligation of Purchaser and Guarantor enforceable against
each of them in accordance with its terms, except as enforceability may be

                                  TERMINATION

terminated as follows:

                 (a)      by mutual agreement of the parties, at any time;

                 (b)      by Purchaser if a Major Loss occurs, provided that
Purchaser gives notice of its intent to terminate within ten (10) Business Days
after it has received notice of such Major Loss;

                 (c)      by Purchaser if it discovers a material breach of any
representation or warranty made by PPI which PPI is unable to cure within
thirty (30) days after having received notice of such breach; and

                 (d)      by PPI if it discovers a material breach of any
representation or warranty made by Purchaser which Purchaser is unable to cure
within thirty (30) days after having received notice of such breach.

                 (e)      by PPI at any time after November 30, 1995, if the
conditions to Closing set forth in Article 6 have not been met by that date,
unless the failure to meet such condition is attributable to any fault or
neglect of PPI; and





                                      45
<PAGE>   51
                 (f)      by Purchaser at any time after November 30, 1995, if
the conditions to Closing set forth in Article 5 have not been met by that
date, unless the failure to meet such condition is attributable to any fault or
neglect of Purchaser; and

                 (g)      by Purchaser pursuant to Section 3.1.2.4.

         If this Agreement terminates pursuant to this Section 10.1, the Asset
Purchase Agreement and the Cockpit Agreement shall remain in full force and
effect, unless such agreements terminate by their own terms.

         Section 10.2     Termination of the Asset Purchase Agreement.  This
Agreement shall automatically terminate if the Asset Purchase Agreement
terminates for any reason, unless PPI and Purchaser agree that this Agreement
shall remain in full force and effect.  If this Agreement does not terminate,
then PPI and Purchaser shall negotiate mutually agreeable terms to adjust the
indemnification limits and the Escrow Fund amount referred to in Article 11 of
the Asset Purchase Agreement consistent with the amount of the Purchase Price
and the terms and conditions of this Agreement.

         Section 10.3     Effect of Termination.  If this Agreement terminates:

                 (a)      neither party shall have any obligation to the other
party, except that such termination shall be without prejudice to the rights of
any party resulting from the intentional or willful breach or violation of the
representations, warranties, covenants or agreements of the other party under
this Agreement, provided that a failure by a party to close when all of the
conditions to such party's obligation to close have been met shall be deemed to
be an intentional breach of such party's covenants and agreements hereunder.

<PAGE>   52
                 (b)      promptly upon termination for any reason, Purchaser

thereof) received from PPI prior to, during and after the Due Diligence Period;

                 (c)      the provisions of Section 3.1.1, Section 10.3, and
Sections 12.1, 12.2, 12.3, 12.4, 12.5, 12.6, 12.7, 12.8 and 12.9 shall survive
the termination of this Agreement and continue in full force and effect.

                                   ARTICLE 11

                                INDEMNIFICATION

         Section 11.1     Indemnification by PPI.  Subject to the provisions of
this Article 11, the Company agrees to indemnify, defend, and hold harmless the
Purchaser and its Affiliates, officers, directors, agents, shareholders,
partners, and employees, (each, a "Purchaser Indemnified Party") from and
against any and all liabilities, losses, claims (whether or not successful),
damages, and expenses (including reasonable fees, and disbursements of counsel)
(collectively, "Liabilities") resulting from or arising out of (i) any breach
of any representation or warranty, covenant or agreement of the Company set
forth in this Agreement, (ii) non-compliance with any applicable transfer or
bulk sales law, or (iii) obligations or liabilities of the Company related to
or arising out of acts, events or omissions occurring prior to the Closing and
not expressly assumed by Purchaser hereunder or indemnified against by
Purchaser pursuant to Section 11.7.3, or (iv) liabilities or obligations
related to any amendment to a Material Contract or Right-of-way Agreement not
delivered to Purchaser prior to the date of this Agreement, unless such
amendment is subsequently delivered to and accepted by Purchaser, provided,





                                      47
<PAGE>   53
however, that the Company shall not be liable under this Section 11.1 to any
Purchaser Indemnified Party for any amount paid in settlement of claims without
the Company's consent, unless such consent was requested and unreasonably
withheld.

         Section 11.2     Survival of Representations and Warranties.  The
representations and warranties set forth in Sections 7.1, 7.2, 7.3, 7.4, and
7.12 shall survive the Closing without limitation of time. The representations
and warranties set forth in Section 7.16 (Environmental Matters) shall survive
the Closing and shall expire three years after the Closing Date. The
representations and warranties set forth in Section 7.17 (Taxes) shall survive
the Closing and shall expire on a date that is ninety (90) days following the
expiration of the applicable statute of limitations.  All other representations
and warranties shall survive the Closing and shall expire two years after the
Closing Date.  Any right of Purchaser to make a claim against the Company for a
breach of any covenant or agreement of the Company herein shall survive the
Closing and shall expire one hundred eighty (180) days after the date on which
the Company was obligated to comply with the covenant or agreement.  Any claim
for breach of a representation and warranty, or covenant or agreement, must be
made by Purchaser by a demand for arbitration to the Company prior to the
expiration of such representation and warranty, or the right to make a claim
for a breach of such covenant or agreement, and any such claims covered by such
demands made by Purchaser to the Company within such time periods shall survive
until resolved.

         Section 11.3     Indemnification by Purchaser.  Purchaser, its
successor and assigns, jointly and severally, agree to indemnify, defend, and
hold harmless the Company and its Affiliates, officers, directors,
shareholders, partners, warrant holders, agents, and employees, (each, an





                                      48
<PAGE>   54
"PPI Indemnified Party") from and against any and all Liabilities resulting
from or arising out of (i) any breach of any representation, warranty, covenant
or agreement of Purchaser or Guarantor set forth in this Agreement or (ii)
obligations or liabilities of the Purchaser with respect to the Business or the
Pipeline Assets, including those which may be imposed upon any PPI Indemnified
Party, related to or arising out of acts, events or omissions occurring after
the Closing and not expressly assumed by any PPI Indemnified Party hereunder
and specifically including (but not limited to) liabilities or obligations
arising from the failure of Purchaser to assume any post-Closing liabilities as
required by Section 2.2, provided, however, that Purchaser shall not be liable
under this Section 11.3 to any PPI Indemnified Party for any amount paid in
settlement of claims without Purchaser's consent unless such consent was
requested and unreasonably withheld, and provided further that the right of the
PPI Indemnified Parties to make a claim for breach of any covenants or
agreements of Purchaser herein shall expire one hundred eighty (180) days after
the date on which the Purchaser was obligated to comply with the covenant or
agreement.

         Section 11.4     Indemnification Claims.

                 (a)      PPI, SPC and Purchaser acknowledge and agree that the
Escrow Fund, established by SPC at Closing, will be used to satisfy claims for
indemnification under the Purchase Agreements, including all indemnification
claims under this Agreement, for which no limit on liability has been
established in accordance with the terms of Section 11.4 of the Asset Purchase
Agreement.

                 (b)      With the exception of (i) claims arising under
Section 11.7.1.1 (ii) claims for fines or penalties imposed by Governmental
Authorities, (iii) claims for Liens that are not





                                      49
<PAGE>   55
Permitted Encumbrances, (iv) claims related to breaches of the agreements of
the Company in Section 9.4, and (v) claims under Section 11.1 (iv), for which
there shall be no minimum claim, Purchaser shall not be entitled to assert any
claim for indemnification hereunder until the aggregate of all indemnifications
claims that may be made pursuant to the Purchase Agreements exceeds the minimum
amount described in Section 11.6 of the Asset Purchase Agreement.  Purchaser
shall follow the notice procedures set forth in Section 11.6 of the Asset
Purchase Agreement for making claims for indemnification hereunder.

         Section 11.5     Limits on Liability.  With the exception of (i)
claims arising under Sections 7.1, 7.2, 7.3, 7.4, and 7.12 (ii) claims for
fines or penalties imposed by Governmental Authorities, (iii) claims for Liens
that are not Permitted Encumbrances, (iv) claims related to breaches of the
agreements of the Company in Section 9.4, and (v) claims under Section
11.1(iv), for which there shall be no limitation of amount, the Company's
maximum liability for Liabilities under the Company's indemnifications under
this Agreement, including without limitation Section 11.7.1.1, shall be the
Escrow Fund, and neither the Company nor any of its Affiliates, shareholders,
officers, directors, agents and employees shall have any liability for such
Liabilities in excess of the Escrow Fund.

         Section 11.6     Intentionally Omitted.

         Section 11.7     Special Environmental Indemnification and
Post-Closing Covenants by Purchaser.

                 11.7.1.1  To the extent that, prior to the date three years
after the Closing Date, Purchaser discovers and notifies PPI and SPC of facts
or circumstances that give rise to Remedial Work (including Remedial Work
related to matters discovered prior to the Closing or





                                      50
<PAGE>   56
disclosed on Schedule 7.16) with respect to the Pipeline Assets or the Business
(except for Remedial Work attributable to (i) changes in Environmental Law
occurring after the Closing Date, or (ii) events occurring or actions of
Persons other than PPI, SPC, SPCT or SIC taken after the Closing Date), the Net
Remedial Cost for such Remedial Work with respect to the Pipeline Assets or the
Business shall be calculated as part of the Aggregate Net Remedial Cost
determined pursuant to the terms of Section 11.7.1.1 of the Asset Purchase
Agreement and shall be paid in accordance with those terms, subject to the
limits set forth in Section 11.7.1.1 of the Asset Purchase Agreement.

         Notwithstanding the preceding portions of this Section 11.7.1.1,
Purchaser shall not be liable for or be required to pay any Net Remedial Costs
resulting from or arising out of any action or omission after Closing of any
PPI Indemnified Party that constitutes or causes a violation of Environmental
Law with respect to the Pipeline Assets or the Business or gives rise to the
need to perform Remedial Work with respect thereto, unless otherwise agreed to
in writing by Purchaser.

                 11.7.1.2  Purchaser shall not alter or change the scope or
methodology of Remedial Work described on Schedule 7.16 except as required by
Applicable Law or as approved by the Company, which approval shall not be
unreasonably withheld, provided, however, that an objection shall not be deemed
unreasonable solely because it is based on an increase in the cost for
performing such Remedial Work.  For so long as PPI has any liability to
Purchaser under Section 11.7.1.1, Purchaser shall use commercially reasonable
efforts to perform and complete all such required Remedial Work and shall keep
PPI and SPC informed of the progress of such Remedial Work.  In addition,
before undertaking any such Remedial





                                      51
<PAGE>   57
Work Purchaser shall notify PPI of the scope and methodology of such Remedial
Work, sufficiently in advance (except as emergency conditions may require
otherwise) to permit PPI to comment on such scope and methodology. Recognizing
that the final decision on scope and methodology rests with Purchaser,
Purchaser shall nonetheless make a good faith effort to reach agreement with
PPI regarding such scope and methodology, recognizing PPI's financial interest
therein.  Purchaser shall provide PPI and SPC with copies of all plans,
reports, and correspondence submitted to any Governmental Authority with
respect to such Remedial Work.  Purchaser will not agree to any such Remedial
Work or other actions that commit or bind PPI or SPC (beyond the payment of
money hereunder) without the prior consent of PPI and SPC.  Purchaser will
provide PPI and SPC with copies of all invoices rendered by Persons actually
performing such Remedial Work, and PPI and SPC shall be deemed to have accepted
the validity and reasonableness of such invoices if it does not notify
Purchaser to the contrary within ten (10) Business Days of receiving the same.

                 11.7.2 (a)  Purchaser and Guarantor acknowledge that (i)
Purchaser has reviewed copies of all documents and other materials related to
environmental matters with respect to the Pipeline Assets and the Business that
were provided by the Company, (ii) the Company has specifically bargained for
relief, as more particularly described herein, from post-Closing liability
resulting from violations of Environmental Law or the performance of Remedial
Work with respect to the Pipeline Assets or the Business, and (iii) the
Purchase Price and Adjusted Purchase Price, as the case may be, reflect
Purchaser's willingness to accept liability (and Guarantor's willingness to

                 (b)      Purchaser has agreed to assume, and Guarantor has
agreed to guarantee the obligation of Purchaser to assume, as of the Closing
all obligations and liabilities resulting from or arising out of any actual or
alleged violation of Environmental Law related to the Pipeline Assets or the
Business, regardless of when such violation was supposed to have occurred, or
the performance of Remedial Work with respect to the Pipeline Assets or the
Business, except for (i) fines and penalties imposed by any Governmental
Authority relating to violations of Environmental Law that occurred prior to
Closing with respect to the Pipeline Assets or the Business, (ii) payments to
be made to Purchaser pursuant to Section 11.7.1.1, (iii) obligations or
liabilities that result from or arise out of any act or omission after the
Closing of any PPI Indemnified Party that constitutes or causes a violation of
Environmental Law with respect to the Business or the Pipeline Assets or gives
rise to the need to perform Remedial Work with respect thereto, unless
otherwise agreed to in writing by Purchaser, and (iv) claims for a breach of
the representations and warranties set forth in Section 7.16 to the extent
Purchaser is entitled to indemnity under this Article 11.

                 (c)      For the avoidance of any doubt, Purchaser, Guarantor
and PPI confirm their agreement that PPI shall have no obligation or liability
post-Closing resulting from or arising out of any actual or alleged violation
of Environmental Law related to the Pipeline Assets or the Business, regardless
of when such violation was supposed to have occurred, or the performance of
Remedial Work with respect to the Pipeline Assets or the Business, except (i)
fines and penalties imposed by any Governmental Authority relating to
violations of Environmental Law that occurred prior to Closing with respect to
the Pipeline Assets or the Business, (ii) payments to be made to Purchaser
pursuant to Section 11.7.1.1, (iii) obligations





                                      53
<PAGE>   59
or liabilities that result from or arise out of any act or omission after the
Closing of any PPI Indemnified Party that constitutes or causes a violation of
Environmental Law with respect to the Business or the Pipeline Assets or gives
rise to the need to perform Remedial Work with respect thereto, unless
otherwise agreed to in writing by Purchaser, and (iv) claims for a breach of
the representations and warranties set forth in Section 7.16 to the extent
Purchaser is entitled to indemnity under this Article 11.

                 11.7.3  Purchaser, its successors and assigns, jointly and
severally, agree to indemnify, defend, and hold harmless each PPI Indemnified
Party  from and against any and all Liabilities resulting from or arising out
of any actual or alleged violation of Environmental Law related to the Pipeline
Assets or the Business, regardless of when such violation was supposed to have
occurred, or the performance of Remedial Work with respect to the Pipeline
Assets or the Business, except for (i) fines and penalties imposed by any
Governmental Authority relating to violations of Environmental Law that
occurred prior to Closing with respect to the Pipeline Assets or the Business,
(ii) payments to be made to Purchaser pursuant to Section 11.7.1.1, (iii)
obligations or liabilities that result from or arise out of any act or omission
after the Closing of any PPI Indemnified Party that constitutes or causes a
violation of Environmental Law with respect to the Business or the Pipeline
Assets or gives rise to the need to perform Remedial Work with respect thereto,
unless otherwise agreed to in writing by Purchaser, and (iv) claims for a
breach of the representations and warranties set forth in Section 7.16 to the
extent Purchaser is entitled to indemnity under this Article 11.
Notwithstanding the preceding provisions of this Section 11.7.3, Purchaser
shall not be liable under this Section 11.7.3 to any





                                      54
<PAGE>   60
PPI Indemnified Party for any amount paid in settlement without Purchaser's
consent unless such consent was requested and unreasonably withheld.

                 11.7.4 Purchaser shall, for a period of five (5) years after
Closing, notify the Company and SPC promptly of any claim made by any
Governmental Authority or by any Person that there has been a violation of
Environmental Law in connection with the Pipeline Assets or the Business, or
occurring on or from the Pipeline or the ROW Real Estate, and shall thereafter
keep the Company and SPC informed of actions being taken or the conduct of
proceedings with respect to such claim, provided that once it has been
reasonably determined to the satisfaction of PPI and SPC that the amount
required to resolve such claim (whether by performing Remedial Work or
otherwise) is less than $250,000, Purchaser shall no longer be obligated to
provide PPI and SPC with information about such claim.

         Section 11.8     Notification; Counsel.  Each Indemnified Party under
this Article 11 will, promptly after the receipt of notice of the commencement
of any action, investigation, claim or other proceeding against such
Indemnified Party in respect of which indemnity may be sought  under this
Article 11, notify the Company and SPC or the Purchaser, as the case may be, in
writing of the commencement thereof.  The failure of any Indemnified Party to
give such notice shall not relieve the indemnifying party from any liability
which it may have to such Indemnified Party unless, and only to the extent
that, such omission materially adversely affects the indemnifying party's
ability to defend in such action, claim or other proceeding.  In case any such
action, claim or other proceeding shall be brought against any Indemnified
Party and it shall notify the indemnifying party of the commencement thereof,
and, except as otherwise stated herein, the indemnifying party shall be
entitled to assume the defense thereof at its own expense,





                                      55
<PAGE>   61
with counsel satisfactory to such Indemnified Party.  Notwithstanding the
foregoing, in any action, claim or proceeding in which both an indemnifying
party, on the one hand, and an Indemnified Party, on the other hand, is, or is
reasonably likely to become, a party, such Indemnified Party shall have the
right to employ separate counsel at the indemnifying party's expense and to
control its own defense of such action, claim or proceeding if, in the
reasonable opinion of counsel to such Indemnified Party, a conflict or
potential conflict exists between the indemnifying party, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate
representation advisable. In any event, the Indemnified Party will reasonably
cooperate with the indemnifying party in any defense undertaken by an
indemnifying party.

         Section 11.9     Net Worth Covenant.

                 (a)      PPI agrees that for a period of five (5) years after
Closing it will maintain a net worth (assets minus liabilities on a GAAP basis
balance sheet adding back the deferred income taxes, if any, attributable to
any like-kind exchange completed in accordance with Section 3.8) in excess of
$250,000.00.  During the five (5) year period, PPI shall provide to Purchaser,
as soon as they are available, but in no event more than sixty (60) days after
year end, annual calendar year GAAP basis financial statements (and more
frequent financial statements if requested by Purchaser) and such other
information as is reasonably necessary for Purchaser to confirm compliance with
the net worth covenants described in this Section 11.9.

                 (b)      PPI may (so long as SIC meets the net worth
requirements set forth in the next sentence), at any time during the five (5)
year period, provide Purchaser with a guaranty, in the form attached hereto as
Exhibit 11.9, from SIC in the amount of $250,000 and upon the delivery of such
guaranty to Purchaser the covenant contained in subsection (a) of this Section





                                      56
<PAGE>   62
11.9 shall be null and void.  Purchaser shall accept the SIC guaranty so long
as SIC has, and agrees to maintain for the remainder of the five (5) year
period, a net worth equal to or greater than $250,000.  If SIC provides the
guaranty described above, PPI shall not thereafter be required to comply with
the requirements of Section 11.9(a), and the guaranty shall state that SIC
shall thereafter provide to Purchaser, at the times the PPI financial
statements would have been required under the preceding subsection (a) of this
Section 11.9, a letter from SIC's independent auditors stating that SIC's net
worth (on a GAAP balance sheet basis adding back the deferred income taxes, if
any, attributable to the proposed like-kind exchange completed in accordance
with Section 3.8 of the Purchase Agreements and those liabilities attributable
to the above market portion of payment obligations under the throughput
agreements described in Section 5.7 of the Asset Purchase Agreement) is at
least equal to $250,000.

parties hereto with respect to the subject





                                      60

<PAGE>   67
business hours to the books and records related to the Business or the Pipeline
Assets that are not included in the Pipeline Assets and PPI will furnish to
Purchaser such additional information and will cooperate with Purchaser in such
other respects as Purchaser may reasonably request, to the extent that such
access and disclosure of such information and cooperation are required by
Purchaser for financial 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 Authorities, so long as such
disclosure, access, and cooperation do not violate the terms of any agreement
to which PPI is bound or any Applicable Law or result in the loss of any
attorney-client or work product privilege.  PPI will use reasonable efforts in
accordance with PPI's normal record maintenance procedures to keep and maintain
all such books and records for a period of five (5) years from the Closing or
longer as may be required by statute, except that notwithstanding any
requirements of PPI's normal record maintenance procedures, PPI shall not

<PAGE>   68
representatives may at PPI's expense have reasonable access during normal
business hours to the books and records related to the Business or Acquired
Assets that are included in the Acquired Assets and Purchaser will furnish to
PPI such additional information and will cooperate with PPI in such other
respects as PPI may reasonably request, to the extent that such access and
disclosure of such information and cooperation are required by PPI for
financial 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 Authorities, so long as such disclosure,
access, and cooperation do not violate the terms of any agreement to which
Purchaser is bound or any Applicable Law or result in the loss of any
attorney-client or work product privilege.  Purchaser will use reasonable
efforts in accordance with Purchaser's normal record maintenance procedures to
keep and maintain all such books and records transferred to Purchaser hereunder
for a period of five (5) years from the Closing or longer as may be required by
statute, except that notwithstanding any requirements of Purchaser's normal
record maintenance procedures, Purchaser shall not destroy books and records
transferred to Purchaser hereunder during such five (5) year period.  From and
after such five (5) year period, Purchaser shall give PPI sixty (60) days prior
notice before destroying any of such books and records, and PPI may at any time

         Section 12.14  Accounts Receivable Collections.  The parties agree
that all accounts receivable payments under the Contracts shall be pro rated as
of the Closing Date.  SPC shall be credited with such amounts attributable to
periods prior to Closing and Purchaser shall be credited with such amounts
attributable to periods after Closing and the Purchase Price shall be adjusted
accordingly.

         Section 12.15  Prorations.  Real Estate property taxes and assessments
for which PPI is liable, water, sewer and utility charges, normal operating
expenses, annual permit or inspection fees (calculated on the basis of the
period covered), and all other charges and fees customarily prorated and
adjusted in similar transactions shall be prorated at Closing on the basis of a
365-day year.  If any item subject to proration cannot be calculated accurately
on the Closing Date, then such item shall be calculated within thirty (30) days
after the Closing Date and any party owing another party a sum of money based
on such subsequent proration(s) shall promptly pay the sum owed, together with
interest thereon at the rate of seven percent (7%) per annum from the Closing
Date to the date of payment if payment is not made within ten (10) days after

         Section 12.16  Guaranty.  Guarantor acknowledges and agrees that it
will derive substantial direct and indirect benefits from providing the
guaranty set forth in this Section 12.16 and Guarantor has determined that it
is in its best interest to provide this guaranty.  Guarantor absolutely and
unconditionally guarantees to PPI and each PPI Indemnified Party the due and
punctual payment of all liabilities and obligations of Purchaser to PPI or each
PPI Indemnified Party, as appropriate, in accordance with the terms of this
Agreement (and specifically including the indemnification obligations set forth
in Article 11).  Guarantor guarantees to PPI and each





                                      64
<PAGE>   70
PPI Indemnified Party the performance of all of Purchaser's obligations,
liabilities, covenants and agreements (and specifically the indemnification
obligations set forth in Article 11) of Purchaser to PPI or each PPI
Indemnified Party, as appropriate.  Guarantor agrees to indemnify and hold PPI
and each PPI Indemnified Party harmless from and against all liability and
expense, including reasonable attorneys' fees, sustained by PPI or any PPI
Indemnified Party by reason of the failure of Purchaser to fully perform and
comply with the terms and obligations of this Agreement.  Guarantor expressly
waives any right to require PPI or any PPI Indemnified Party to bring any
action, or exhaust its rights, against Purchaser or any other person, or to
require that resort be had to any assets of Purchaser before pursuing the
Guarantor under this Section 12.16.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their authorized officers as of the date first above
written.

terms of this Agreement shall be calculated as part of the Aggregate Adjusted
Purchase Price for purposes of determining SPC's right to terminate the Asset
Purchase Agreement pursuant to Section 10.1(c) therein.

                 2.3.2    Intentionally Omitted.

         Section 2.4      Allocation of Purchase Price Amongst Acquired Assets.
The Purchase Price shall be allocated amongst the Property in accordance with
the fair market values set forth on Schedule 2.4.  Neither party shall take any
position inconsistent with Schedule 2.4 in any filing with the Internal Revenue
Service or for any other purpose.

         Section 2.5      Intentionally Omitted.

         Section 2.6      Payment of Taxes and Closing Costs.  Purchaser shall
be responsible for and shall pay any and all state sales taxes (except with
respect to any sales tax in Virginia, which





                                      13
<PAGE>   19
shall be shared equally by SIC and Purchaser) arising in connection with the
sale of the Property; provided, however, that all closing costs in connection
with the sale of the Real Property or transfer of the rights under the
Right-of-way Agreements including transfer taxes and recording fees, shall be
paid equally by SIC and Purchaser, except that title insurance premiums shall
be paid by Purchaser.

         Section 2.7      Risk of Loss.

                 (a)      The risk of loss of the Property shall pass to
Purchaser at Closing.  If there is any loss, damage, breakdown, or casualty to
any of the Property prior to Closing that does not constitute either (i) a
loss, damage, breakdown, or casualty that has been repaired or replaced to the
reasonable satisfaction of Purchaser, or (ii) a loss, damage, breakdown, or
casualty fully covered by insurance proceeds which have been assigned to
Purchaser and insurance retentions paid by SIC to Purchaser, the Purchase Price
shall be reduced by the cost to repair or replace such assets, estimated if
necessary.  If there is reasonable doubt whether a loss, damage, breakdown, or
casualty is fully covered by insurance and the payment of insurance retentions
by SIC, Purchaser may reduce the Purchase Price by the cost of repairing or
replacing such assets, in which case SIC shall not assign the insurance
proceeds or pay any insurance retentions to Purchaser.  The cost of repairing
or replacing such assets shall be such cost or estimated cost as is agreed upon
between the parties.

                 (b)      Notwithstanding the above provisions of this Section
2.7, if any repair or replacement is reasonably expected to cause the Average
Monthly Revenue to decrease by five percent (5%) or more during the month
immediately following Closing, Purchaser may, in lieu of accepting insurance
proceeds and any insurance retentions or a reduction in the Purchase





                                      14

Price, delay the Closing hereunder on the portion of the Property constituting
and relating to the Real Property and under the Asset Purchase Agreement on the
portion of the Acquired Assets thereunder constituting the Cockpit Terminal
until SPC has completed such repair or replacement to the reasonable
satisfaction of Purchaser, provided, however, that if Purchaser elects to delay
the Closing for the Cockpit Terminal, SIC, SPC and PPI, all, but not
separately, may elect to delay the Closing hereunder, the Closing with respect
to all of the Acquired Assets under the Asset Purchase Agreement and the
Closing contemplated under the PPI Agreement until such time as the Closing
under the Purchase Agreements can take place simultaneously.

                            MATTERS PRIOR TO CLOSING

         Section 3.1      Due Diligence.

                 3.1.1    Examination of Records and Assets.  During the Due
Diligence Period, (i) Purchaser and its agents may examine the Property, and
such books, records, files, and documents of the Company as relate to the
Property, (ii) the Company shall make available to Purchaser and its agents for
review all information concerning the Property which they may request, and
(iii) the Company will make available to Purchaser the officers and any key
employees of the Company to answer questions and to discuss the Company and the
Property all in a manner that does not unduly disrupt the Property and the
operation of the Company's business.  If the Closing does not occur, Purchaser
shall promptly return to the Company, at Purchaser's expense, (i) all documents
(including any copies thereof) received from the Company before, during or
after the Due Diligence Period, and (ii) any documents or materials





                                      15
<PAGE>   21
that Purchaser or its advisers have generated that contain or disclose
information from the documents received from the Company.  Prior to Closing,
except as required in connection with Kaneb Pipe Line Partners, L.P.'s
registration statement filed under the Securities Act of 1933 and the related
offering of partnership units, Purchaser shall maintain in confidence any
information or data received from the Company in the course of conducting its
due diligence, including without limitation the environmental due diligence
provided for in Section 3.1.2, and shall not use the same for any purpose
except in connection with the transaction contemplated by this Agreement,
provided, that the foregoing confidentiality requirement shall remain in effect
after the Closing with respect to the financial statements of the Company and
its Affiliates.  Prior to Closing, and thereafter with respect to the financial
statements of the Company and its Affiliates, except as required in connection
with Kaneb Pipe Line Partners, L.P.'s registration statement filed under the
Securities Act of 1933 and the related offering of partnership units, Purchaser
shall not disclose any such information or data to any third person except to
the extent that (i) such information or data is already in the public domain,
or (ii) such disclosure is compelled or required by subpoena or similar legal
process.

                 3.1.2    Environmental Due Diligence.

                 3.1.2.1  Audits and Surveys.  During the Due Diligence Period,
Purchaser may  cause Audits to be conducted by the Purchaser's Consultant, at
its expense, of any of the Real Property, the Pepco Pipeline (to the extent
such Audits are permitted by Pepco) or ROW Real Estate (to the extent such
Audits are permitted under the applicable Right-of-way Agreement).  The scope,
methodology, timing, and conduct of all such Audits shall be subject to the
prior approval of SIC, which approval shall not be unreasonably withheld,
except that it shall not be





                                      16
<PAGE>   22
unreasonable for SIC to withhold its approval based on SIC's reasonable opinion
that such Audit is not permitted under the relevant Right-of-way Agreement.
All Audits shall be conducted so as to avoid unduly disrupting the Property or
the business of Pepco, SIC and/or SPC.  All such Audits shall be completed
within the Due Diligence Period if, and to the extent that, Purchaser wishes to
rely on the results of such Audits in proposing any adjustment to the Purchase
Price under Section 3.1.2.2.  The Purchaser shall cause the Purchaser's
Consultant to deliver simultaneously to SIC copies of all data, reports,
surveys, or audits, or drafts thereof that it delivers to Purchaser with
respect to the Property and deliver to SIC promptly after signing this
Agreement copies of all data, reports, surveys, audits, or drafts thereof
delivered to Purchaser with respect to the Property prior to the signing of
this Agreement.

                 3.1.2.2  Purchase Price Adjustment for Certain Remedial Work.

                          (a)     If the Audits prepared by Purchaser's
Consultant disclose that Remedial Work is required with respect to the
Property, then Purchaser shall record and track such Remedial Work with any
Remedial Work disclosed pursuant to Section 3.1.2.2 of the Asset Purchase
Agreement and Section 3.1.2.2 of the PPI Agreement and Purchaser may deliver to
SIC and SPC an Environmental Adjustment Request to request an adjustment to the
Purchase Price subject to this subsection (a) and subsections (b), (c) and (d)
below.  The Net Remedial Cost for Remedial Work with respect to the Property
disclosed pursuant to this Section 3.1.2.2 shall be aggregated with the Net
Remedial Cost for Remedial Work under Section 3.1.2.2 of the Asset Purchase
Agreement and Section 3.1.2.2 of the PPI Agreement for purposes of (i)
calculating the one million dollar ($1,000,000) threshold described in Section
3.1.2.2 of the Asset Purchase Agreement and the Remaining Threshold, (ii)
delivering an Environmental





                                      17
<PAGE>   23
Adjustment Request to SPC under the Asset Purchase Agreement, to PPI under the
PPI Agreement and/or SIC under this Agreement, (iii) calculating the Net
Remedial Cost to determine Purchaser's right to terminate pursuant to Section
10.1(h) of the Asset Purchase Agreement, and (iv) calculating the Aggregate
Adjusted Purchase Price to determine SPC's right to terminate under Section
10.1(c) of the Asset Purchase Agreement.

                          (b)     The time limitations and procedures for (i)
delivering an Environmental Adjustment Request, and (ii) determining the Net
Remedial Cost for Remedial Work required with respect to the Property set forth
in Section 3.1.2.2 of the Asset Purchase Agreement shall apply hereunder.

                          (c)     Any Environmental Adjustment Request that
includes a description of Remedial Work required with respect to the Property
shall be delivered to SIC and SPC.

                          (d)     To the extent, if any, that the Aggregate Net
Remedial Cost under the Purchase Agreements exceeds one million dollars
($1,000,000) and any of the excess amount of such Aggregate Net Remedial Cost
is attributable to the Property as determined in accordance with the procedures
set forth in Section 3.1.2.2(e) of the Asset Purchase Agreement, then the
Purchase Price shall be reduced by the amount of such excess in accordance with
Section 3.1.2.2 of the Asset Purchase Agreement.

                 3.1.2.3  Purchase Price Adjustment for Other Remedial Work.
Notwithstanding any terms contained in Sections 3.1.2.1 and 3.1.2.2, (i) if
there is a violation of Environmental Law that occurs after the date of this
Agreement and prior to Closing that requires Remedial Work with respect to the
Property that is not completed prior to Closing either to the reasonable
satisfaction of Purchaser or to the satisfaction of the applicable Governmental
Authority, or (ii)





                                      18
<PAGE>   24
if after the Due Diligence Period and prior to Closing a violation of
Environmental Law that requires Remedial Work with respect to the Property is
discovered that could not reasonably have been discovered during the Due
Diligence Period by a Phase I and Phase II environmental audit and such
Remedial Work is not completed prior to Closing either to the reasonable
satisfaction of Purchaser or to the satisfaction of the applicable Governmental
Authority, then in each such case Purchaser shall be entitled to an adjustment
to the Aggregate Purchase Price determined in accordance with the procedures
set forth in Sections 3.1.2.2 and 3.1.2.3 of the Asset Purchase Agreement
without regard to the 75 day time period for proposing such adjustment.

                 3.1.2.4  Other Environmental Liabilities.  If, prior to
Closing, Purchaser or SIC receives notice of a claim from, or discovers or
receives notice of any facts or circumstances reasonably expected by ICF Kaiser
to give rise to a claim by, any Person or Governmental Authority for liability
or obligation (other than for Remedial Work) related to an alleged violation of
Environmental Law with respect to the Property, it shall promptly notify the
other parties hereto (the "Notice").  Thereafter, SIC and Purchaser shall
attempt to agree on whether a Purchase Price adjustment or other agreeable
mechanism is warranted with respect to such claim.  If the parties are unable
to agree, SIC may in its discretion assume responsibility for such claim and
provide Purchaser with an indemnification against such claim reasonably
satisfactory to Purchaser.  If within thirty (30) days after delivery of the
Notice (i) the parties are unable to agree on an adjustment to the Purchase
Price or other agreeable mechanism, and (ii) SIC fails to assume responsibility
for such claim and provide an indemnification reasonably satisfactory to
Purchaser, then Purchaser shall have the right to terminate this Agreement.

         Section 3.2      Real Property Matters.

                 (a)      Purchaser shall at its expense from the date of this
Agreement through Closing review the status of SIC's title to the Real
Property.  As of the date of this Agreement, Purchaser has received (i) the
survey listed on the attached Schedule 3.2 and (ii) the current title binder
for the Real Property listed on the attached Schedule 3.2 obtained from
Commonwealth Land Title Insurance Company with respect to the Real Property
indicating therein Purchaser as the proposed insured (with the cost of any
update work necessary to cause the issuance of the current title binder to be
paid equally by Purchaser and SIC).  The information set forth on such survey
and in such title binder (but only to the extent copies of the documents
referenced therein have been provided to Purchaser) is referred to herein as
the "Current Title Information".  Purchaser shall have the right, at its
expense, to cause to be prepared to its satisfaction current surveys of any or
all of the parcels of Real Property.

                 (b)      All Real Property Matters disclosed in the Current
Title Information are listed on Schedule 3.2 and Purchaser shall not have the
right or the opportunity to raise any other Real Property Matters based on the
Current Title Information.

                 (c)      If Purchaser's review prior to Closing discloses a
Real Property Matter not disclosed in the Current Title Information, Purchaser
shall notify SIC thereof within four (4) Business Days of discovery.

                 (d)      With respect to Real Property Matters listed on
Schedule 3.2 and any Real Property Matters for which notice is sent to SIC
under clause (c) above, SIC shall at its expense attempt to remedy or cure such
Real Property Matter, provided that, except for payments





                                      20
<PAGE>   26
necessary to release existing mortgages and any Lien related to said mortgages
on Real Property owned by SIC, SIC shall have no obligation to spend any amount
in excess of five percent (5%) of the Purchase Price to remedy or cure a Real
Property Matter.  If SIC is unable to remedy or cure one or more Real Property
Matters within 30 days from Purchaser's notification thereof, the parties shall
attempt in good faith to negotiate an adjustment in the Purchase Price that
will compensate Purchaser for the cost of curing or remedying the Real Property
Matter or for otherwise accepting the Real Property as is.  If the parties are
unable to agree on an adjustment to the Purchase Price as a result of a Real
Property Matter this Agreement shall terminate with respect to all Property
other than the Right-of-way Agreements and the Purchase Price shall be reduced
to one dollar ($1.00) plus Purchaser's assumption with respect to the
Right-of-way Agreements under Section 2.2, in which event the Purchaser shall
still be obligated to acquire the Cockpit Terminal pursuant to the Asset
Purchase Agreement and the Purchaser shall be required to lease the Real
Property from SIC in accordance with the terms of a lease to be negotiated and
concluded at the appropriate time; provided, however, that the Purchaser shall
not be required to acquire the Cockpit Terminal pursuant to the Asset Purchase
Agreement or to lease the Real Property from SIC if SIC and the Purchaser
cannot agree on the terms of such lease.

         Section 3.3      Consents.  SIC shall use reasonable commercial
efforts promptly to obtain the consent, waiver or approval of each Person whose
consent, waiver, or approval is required to effect an assignment of any of the
Material Contracts or Right-of-way Agreements, or to transfer any of the
Property to Purchaser or otherwise in connection with this transaction, and,
where appropriate, to effect a novation of such Material Contracts or
Right-of-way Agreements.





                                      21
<PAGE>   27
Purchaser shall cooperate with SIC in obtaining such items as reasonably
requested to do so by SIC.

         Section 3.4      Hart-Scott-Rodino.  SIC and Purchaser shall each
comply with the notification, waiting period and other requirements of the HSR
Act.  Each party shall take reasonable steps to provide information to and
otherwise cooperate with the other party for the purposes of making required
filings under the HSR Act.

         Section 3.5      Purchaser's Licenses, Permits and Approvals.
Purchaser shall exercise reasonable commercial efforts promptly to obtain all
licenses and permits required by Purchaser to purchase the Property.

         Section 3.6      Intentionally Omitted.

         Section 3.7      Notification.  Each party shall promptly notify the
other parties if it has Knowledge of (i) any information indicating that any
representation or warranty of any other party is or may be untrue in any
material respect, (ii) any covenant to be performed by such other party that is
not being performed, or (iii) any circumstance that would impede or interfere
with the Closing, except that no party shall be liable for a breach of this
covenant unless and except to the extent that the affected party is materially
prejudiced or damaged thereby.

         Section 3.8      Deferred Like-Kind Exchange.  Upon the request of
SIC, made at least two Business Days prior to the Closing Date, Purchaser shall
execute such documents as may reasonably be required to acknowledge (i) notice
of SIC's intention to accomplish a deferred like-kind exchange of part or all
of the Property pursuant to Section 1031 of the Code and Treasury Regulation
1.1031(k)-1 and (ii) the assignment of part or all of SIC's right, title and





                                      22
<PAGE>   28
interest in and to (but not SIC's obligations under) this Agreement to a
qualified intermediary (within the meaning of Treasury Regulation Section
1.1031(k)-1(g)(4)).

         Section 3.9      Actions Necessary to Consummate.  From and after the
date of this Agreement, each of the parties shall in good faith take such
action as may be commercially reasonable to consummate the transactions
contemplated by this Agreement.

providing coverage which is the same or comparable to that provided under the
cancelled, terminated, or lapsed policies.  Without the consent of Purchaser,
such consent not to be unreasonably withheld, SIC shall not enter into, amend

Purchaser gives notice of its intent to terminate within ten (10) Business Days
after it has received notice of such Major Loss;





                                      40
<PAGE>   46
                 (e)      by Purchaser if it discovers a material breach of any
representation or warranty made by SIC which SIC is unable to cure within
thirty (30) days after having received notice of such breach;

contained in Section 7.16 of Asset Purchase Agreement as it applies to the Real
Property, (iii) non-compliance with any applicable transfer or bulk sales law,
and (iv) obligations or liabilities of the Company related to or arising out of
acts, events or omissions occurring prior to the Closing that are related to
the Property and not expressly assumed by Purchaser or indemnified against by
Purchaser hereunder or in the Asset Purchase Agreement, provided, however, that
SPC shall not be liable under this Section 11.1 to any Purchaser Indemnified
Party for any amount paid in settlement of claims without SPC's and SIC's
consent, unless such consent was requested and unreasonably withheld.

herein, except a breach of those representations and warranties set forth in
Sections 7.1, 7.2, 7.3, 7.4, 7.7 and 7.12.  The indemnification obligations
assumed by SPC under this Section 11.1 shall be subject to and treated in
accordance with Sections 11.2, 11.5, 11.6, 11.7 and 11.8 of the Asset Purchase
Agreement, as if such indemnification obligations were made under the Asset
Purchase Agreement.

                 (b)      Subject to the provisions of this Article 11, the
Company agrees to indemnify, defend, and hold harmless the Purchaser and its
Affiliates, officers, directors, agents, shareholders, partners, and employees,
(each, a "Purchaser Indemnified Party") from and against any and all
liabilities, losses, claims (whether or not successful), damages, and expenses
(including reasonable fees, and disbursements of counsel)  (collectively,
"Liabilities") resulting from or arising out of (i) any breach of any
representation or warranty, of the Company set forth in Sections 7.1, 7.2, 7.3,
7.4, 7.7 and 7.12 of this Agreement or (ii) liabilities or obligations related
to any amendment to a Material Contract or Right-of-way Agreement not delivered
to





                                      43
<PAGE>   49
Purchaser prior to the date of this Agreement, unless such amendment is
subsequently delivered to and accepted by Purchaser, provided, however, that
the Company shall not be liable under this Section 11.1 to any Purchaser
Indemnified Party  for any amount paid in settlement of claims without the
Company's consent, unless such consent was requested and unreasonably withheld.

         Section 11.2     Survival of Representations and Warranties.  The
representations and warranties set forth in Sections 7.1, 7.2, 7.3, 7.4, 7.7
and 7.12 shall survive the Closing without limitation of time. The
representations and warranties set forth in Section 7.16 (Environmental
Matters) shall survive the Closing and shall expire three years after the
Closing Date.  All other representations and warranties shall survive the
Closing and shall expire two years after the Closing Date.  Any right of
Purchaser to make a claim against the Company for a breach of any covenant or
agreement of the Company herein shall survive the Closing and shall expire one
hundred eighty (180) days after the date on which the Company was obligated to
comply with such covenant or agreement.  Any claim for breach of a
representation and warranty, or covenant or agreement, must be made by
Purchaser by a demand for arbitration to the Company prior to the expiration of
such representation and warranty, or the right to make a claim for a breach of
such covenant or agreement, and any such claims covered by such demands made by
Purchaser to the Company within such time periods shall survive until resolved.

         Section 11.3     Indemnification by Purchaser.  Purchaser, it
successors and assigns, jointly and severally, agree to indemnify, defend, and
hold harmless the Company and their Affiliates, officers, directors,
shareholders, partners, warrant holders, agents, and employees, (each, an "SIC
Indemnified Party") from and against any and all Liabilities resulting from or
arising out





                                      44
<PAGE>   50
of (i) any breach of any representation, warranty, covenant or agreement of
Purchaser or Guarantor set forth in this Agreement or (ii) obligations or
liabilities of the Purchaser with respect to the Property, including those
which may be imposed upon any SIC Indemnified Party, related to or arising out
of acts, events or omissions occurring after the Closing and not expressly
assumed by any SIC Indemnified Party hereunder and specifically including (but
not limited to) liabilities or obligations arising from the failure of
Purchaser to assume any post-Closing liabilities as required by Section 2.2,
provided, however, that Purchaser shall not be liable under this Section 11.3
to any SIC Indemnified Party for any amount paid in settlement of claims
without Purchaser's consent unless such consent was requested and unreasonably
withheld, and provided further that the right of the SIC Indemnified Parties to
make a claim for breach of any covenants or agreements of Purchaser herein
shall expire one hundred eighty  (180) days after the date on which the
Purchaser was obligated to comply with the covenant or agreement.

         Section 11.4     Establishment of Escrow Fund.  SIC, SPC and Purchaser
acknowledge and agree that the Escrow Fund, established by SPC at Closing, will
be used to satisfy claims for indemnification under the Purchase Agreements,
including all indemnification claims under this Agreement, for which no limit
on liability has been established in accordance with the terms of Section 11.4
of the Asset Purchase Agreement.  Purchaser shall follow the procedures set
forth in Section 11.4 of the Asset Purchase Agreement for making claims for
indemnification under this Agreement.

         Section 11.5     Limits on Liability.  With the exception of (i)
claims arising under Sections 7.1, 7.2, 7.3, 7.4, 7.7 (but only to the extent
that any claim is based on the specific wording





                                      45
<PAGE>   51
in each of the limited warranty deeds by which the Real Property is conveyed)
and 7.12 (ii) claims for fines or penalties imposed by Governmental
Authorities, (iii) claims for Liens that are not Permitted Encumbrances, and
(iv) claims under Section 11.1(b)(ii), for which there shall be no limitation
of amount, the Company's maximum liability for Liabilities under the Company's
indemnifications under this Agreement, including without limitation Section
11.7.1.1, shall be the Escrow Fund, and neither the Company, nor any of their
Affiliates, shareholders, warrant holders, partners, officers, directors,
agents and employees shall have any liability for such  Liabilities in excess
of the Escrow Fund.

         Section 11.6     Minimum Claim Amount.  With the exception of (i)
claims arising under Section 11.7.1.1, (ii) claims for fines or penalties
imposed by Governmental Authorities, (iii) claims for Liens that are not
Permitted Encumbrances, (iv) claims under Section 11.1(b)(ii), and (v) fifty
percent (50%) of any claim for indemnification with respect to a breach of the
representations and warranties set forth in Sections 7.24(a), (b) and (c) with
respect to the Pepco Pipeline, for which there shall be no minimum claim,
Purchaser shall not be entitled to assert any claim for indemnification
hereunder until the aggregate of all claims for indemnification under this
Agreement, the PPI Agreement and the Asset Purchase Agreement collectively
exceeds Seven Hundred and Fifty Thousand Dollars ($750,000) and then only for
amounts in excess of such Seven Hundred and Fifty Thousand Dollars ($750,000).
Purchaser shall follow the notice procedures set forth in Section 11.6 of the
Asset Purchase Agreement for making claims for indemnification hereunder.

         Section 11.7     Special Environmental Indemnification and
Post-Closing Covenants by Purchaser.





                                      46
<PAGE>   52
                 11.7.1.1  To the extent that, prior to the date three years
after the Closing Date, Purchaser discovers and notifies SIC and SPC of facts
or circumstances that give rise to Remedial Work (including Remedial Work
related to matters discovered prior to the Closing or disclosed on Schedule
7.16) with respect to the Property (except for Remedial Work attributable to
(i) changes in Environmental Law occurring after the Closing Date, or (ii)
events occurring or actions of Persons other than SIC, SPC, SPCT or PPI taken
after the Closing Date), the Net Remedial Cost for Remedial Work with respect
to the Property shall be calculated as part of the Aggregate Net Remedial Cost
determined pursuant to the terms of Section 11.7.1.1 of the Asset Purchase
Agreement and shall be paid in accordance with those terms, subject to the
limits set forth in Section 11.7.1.1 of the Asset Purchase Agreement.

         Notwithstanding the preceding portions of this Section 11.7.1.1,
Purchaser shall not be liable for or be required to pay any Net Remedial Costs
resulting from or arising out of any action or omission after Closing of any
SIC Indemnified Party that constitutes or causes a violation of Environmental
Law with respect to the Property or gives rise to the need to perform Remedial
Work with respect thereto, unless otherwise agreed to in writing by Purchaser.

                 11.7.1.2  Purchaser shall not alter or change the scope or
methodology of Remedial Work described on Schedule 7.16 except as required by
Applicable Law or as approved by the Company, which approval shall not be
unreasonably withheld, provided, however, that an objection shall not be deemed
unreasonable solely because it is based on an increase in the cost for
performing such Remedial Work. For so long as SPC has any liability to
Purchaser under Section 11.7.1.1, Purchaser shall use commercially reasonable
efforts to perform and complete all such required Remedial Work and shall keep
SIC informed of the





                                      47
<PAGE>   53
progress of such Remedial Work.  In addition, before undertaking any such
Remedial Work  Purchaser shall notify SIC of the scope and methodology of such
Remedial Work, sufficiently in advance (except as emergency conditions may
require otherwise) to permit SIC to comment on such scope and methodology.
Recognizing that the final decision on scope and methodology rests with
Purchaser, Purchaser shall nonetheless make a good faith effort to reach
agreement with SIC regarding such scope and methodology, recognizing SIC's
financial interest therein.  Purchaser shall provide SIC with copies of all
plans, reports, and correspondence submitted to any Governmental Authority with
respect to such Remedial Work.  Purchaser will not agree to any such Remedial
Work or other actions that commit or bind SIC or SPC (beyond the payment of
money hereunder) without the prior consent of SIC and SPC.  Purchaser will
provide SIC with copies of all invoices rendered by Persons actually performing
such Remedial Work, and SIC shall be deemed to have accepted the validity and
reasonableness of such invoices if it does not notify Purchaser to the contrary
within ten (10) Business Days of receiving the same.

                 11.7.2 (a) Purchaser and Guarantor acknowledge that (i)
Purchaser has reviewed copies of all documents and other materials related to
environmental matters with respect to the Property that were provided by the
Company, (ii) the Company has specifically bargained for relief, as more
particularly described herein, from post-Closing liability resulting from
violations of Environmental Law or the performance of Remedial Work with
respect to the Property and (iii) the Purchase Price and Adjusted Purchase
Price, as the case may be, reflect Purchaser's willingness to accept liability
( and Guarantor's willingness to guarantee Purchaser's obligation to accept
such liability) with respect to such matters as more fully described below.





                                      48
<PAGE>   54
                          (b)     Purchaser has agreed to assume, and Guarantor
has agreed to guarantee the obligation of Purchaser to assume, as of the
Closing all obligations and liabilities resulting from or arising out of any
actual or alleged violation of Environmental Law related to the Property,
regardless of when such violation was supposed to have occurred, or the
performance of Remedial Work with respect to the Property, except for (i) fines
and penalties imposed by any Governmental Authority relating to violations of
Environmental Law that occurred prior to Closing with respect to the Property,
(ii) payments to be made to Purchaser pursuant to Section 11.7.1.1, (iii)
obligations or liabilities that result from or arise out of any act or omission
after the Closing of any SIC Indemnified Party that constitutes or causes a
violation of Environmental Law with respect to the Property or gives rise to
the need to perform Remedial Work with respect thereto, unless otherwise agreed
to in writing by Purchaser, and (iv) claims for a breach of the representations
and warranties set forth in Section 7.16 to the extent Purchaser is entitled to
indemnity under this Article 11.

                          (c)     For the avoidance of any doubt, Purchaser,
Guarantor, and SIC confirm their agreement that SIC shall not have any
obligation or liability post-Closing resulting from or arising out of any
actual or alleged violation of Environmental Law related to the Property,
regardless of when such violation was supposed to have occurred, or the
performance of Remedial Work with respect to the Property except (i) fines and
penalties imposed by any Governmental Authority relating to violations of
Environmental Law that occurred prior to Closing with respect to the Property,
(ii) payments to be made to Purchaser pursuant to Section 11.7.1.1, (iii)
obligations or liabilities that result from or arise out of any act or omission
after Closing of any SIC Indemnified Party that constitutes or causes a
violation of Environmental





                                      49
<PAGE>   55
Law with respect to the Property or gives rise to the need to perform Remedial
Work with respect thereto, unless otherwise agreed to in writing by Purchaser,
and (iv) claims for a breach of the representations and warranties set forth in
Section 7.16 to the extent Purchaser is entitled to indemnity under this
Article 11.

                 11.7.3  Purchaser, its successors and assigns, jointly and
severally, agree to indemnify, defend, and hold harmless each SIC Indemnified
Party  from and against any and all Liabilities resulting from or arising out
of any actual or alleged violation of Environmental Law related to the
Property, regardless of when such violation was supposed to have occurred, or
the performance of Remedial Work with respect to the Property, except for (i)
fines and penalties imposed by any Governmental Authority relating to
violations of Environmental Law that occurred prior to Closing with respect to
the Property, (ii) payments to be made to Purchaser pursuant to Section
11.7.1.1, (iii) obligations or liabilities that result from or arise out of any
act or omission after Closing of any SIC Indemnified Party that constitutes or
causes a violation of Environmental Law with respect to the Property or gives
rise to the need to perform Remedial Work with respect thereto, unless
otherwise agreed to in writing by Purchaser, and (iv) claims for a breach of
the representations and warranties set forth in Section 7.16 to the extent
Purchaser is entitled to indemnity under this Article 11.   Notwithstanding the
preceding provisions of this Section 11.7.3, Purchaser shall not be liable
under this Section 11.7.3 to any SIC Indemnified Party for any amount paid in
settlement without Purchaser's consent unless such consent was requested and
unreasonably withheld.

                 11.7.4  Purchaser shall, for a period of five (5) years after
Closing, notify the Company and SPC promptly of any claim made by any
Governmental Authority or by any





                                      50
<PAGE>   56
Person that there has been a violation of Environmental Law in connection with
the Property, or occurring on or from the Real Property or the ROW Real Estate,
and shall thereafter keep the Company and SPC informed of actions being taken
and/or the conduct of proceedings with respect to such claim, provided that
once it has been reasonably determined to the satisfaction of SIC that the
amount required to resolve such claim (whether by performing Remedial Work or
otherwise) is less than $250,000, Purchaser shall no longer be obligated to
provide SIC and SPC with information about such claim.

         Section 11.8     Notification; Counsel.  Each Indemnified Party under
this Article 11 will, promptly after the receipt of notice of the commencement
of any action, investigation, claim or other proceeding against such
Indemnified Party in respect of which indemnity may be sought  under this
Article 11, notify the Company and SPC or the Purchaser, as the case may be, in
writing of the commencement thereof. The failure of any Indemnified Party to
give such notice shall not relieve the indemnifying  party from any liability
which it may have to such Indemnified Party unless, and only to the extent
that, such omission materially adversely affects the indemnifying party's
ability to defend in such action, claim or other proceeding. In case any such
action, claim or other proceeding shall be brought against any Indemnified
Party and it shall notify the indemnifying party of the commencement thereof,
and, except as otherwise stated herein, the indemnifying party shall be
entitled to assume the defense thereof at its own expense, with counsel
satisfactory to such Indemnified Party.  Notwithstanding the foregoing, in any
action, claim or proceeding in which both an indemnifying party, on the one
hand, and an Indemnified Party, on the other hand, is, or is reasonably likely
to become, a party, such Indemnified Party shall have the right to employ
separate counsel at the indemnifying party's





                                      51
<PAGE>   57
expense and to control its own defense of such action, claim or proceeding if,
in the reasonable opinion of counsel to such Indemnified Party, a conflict or
potential conflict exists between the indemnifying party, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate
representation advisable. In any event, the Indemnified Party will reasonably
cooperate with the indemnifying party in any defense undertaken by an
indemnifying party.

         Section 11.9     Net Worth Statement.  SIC hereby represents and
warrants to Purchaser  that as of the Closing Date it will have a net worth
(assets minus liabilities on a GAAP basis balance sheet adding back those
liabilities attributable to the above market portion of payment obligations
under the throughput agreements described in Section 5.7 of the Asset Purchase
Agreement and also deferred income taxes, if any, attributable to any like kind
exchange completed in accordance with Section 3.8 of any of the Purchase
Agreements) of not less than $30,000,000.

         Section 12.2     Successors and Assigns.  This Agreement shall inure
to the benefit of and be binding upon the successors and permitted assigns of
the parties hereto.  No party hereto may assign its rights under this Agreement
without the consent of the other party, except that Purchaser may assign its
rights under this Agreement to any Affiliate, but such assignment shall not
relieve Purchaser or Guarantor of any of their obligations hereunder to the
extent such obligations are not performed by Purchaser's assignee.

         Section 12.3     Amendment and Waiver.

                 (a)      No failure or delay on the part of any party hereto
in exercising any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or
remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. The remedies provided for herein are cumulative
and are not exclusive of any remedies that may be available to any party hereto
at law, in equity or otherwise.

                 (b)      Any amendment, supplement or modification of or to
any provision of this Agreement, any waiver of any provision of this Agreement,
and any consent to any departure by any party hereto from the terms of any

in writing and signed by all parties hereto, or, in the case of a waiver, by
the party waiving compliance, and (ii) only in the specific instance and for
the specific purpose for which made or given.

be entitled in any arbitration hereunder to recover its reasonable attorney's
fees and all costs and expenses of the arbitration.

         Section 12.6     Severability.  If any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions hereof shall not be in any way impaired, unless the
provisions held invalid, illegal or unenforceable shall substantially impair

         Section 12.8     Expenses.  Each party will bear its own expenses
incurred in connection with the negotiation and execution of this Agreement,
and Purchaser shall pay its expenses incurred in carrying out due diligence,
including Audits.

         Section 12.9     Publicity.  Except as may be required by Applicable
Law, or as required in connection with Kaneb Pipe Line Partners L.P.'s
registration statement filed under the Securities Act of 1933 and the related
offering of partnership units, none of the parties shall issue a publicity
release or announcement or otherwise make any public disclosure concerning this
Agreement without the prior approval of the other party. If any announcement is
required by law to be made by either party , prior to making such announcement
such party will deliver a draft of such announcement to the other party and
shall give the other party an opportunity to comment thereon.

         Section 12.10    Further Assurances.  Each party shall execute such
documents and perform such further reasonable acts (including without
limitation reasonable action to obtain any consents, exemptions,
authorizations, or other actions by, or giving any notices to, or making any
filings with, any Governmental Authority or any other Person) as may be
reasonably required or desirable to carry out or to perform the provisions of
this Agreement.

         Section 12.11.A  Post-Closing Access to Books and Records by
Purchaser.  For a period of five (5) years after the Closing Date, subject to
reasonable advance notice of time and purpose and to the execution by Purchaser
of reasonable confidentiality undertakings, Purchaser and its authorized
representatives may at Purchaser's expense have reasonable access during normal
business hours to the books and records related to the Property that are not
included in the Property and SIC will furnish to Purchaser such additional
information and will cooperate with





                                      56
<PAGE>   62
Purchaser in such other respects as Purchaser may reasonably request, to the
extent that such access and disclosure of such information and cooperation are
required by Purchaser for financial 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 Authorities, so
long as such disclosure, access, and cooperation do not violate the terms of
any agreement to which SIC is bound or any Applicable Law or result in the loss
of any attorney-client or work product privilege.  SIC will use reasonable
efforts in accordance with SIC's normal record maintenance procedures to keep
and maintain all such books and records for a period of five (5) years from the
Closing or longer as may be required by statute, except that notwithstanding
any requirements of SIC's normal record maintenance procedures, SIC shall not
destroy such books and records during such five (5) year period.  From and
after such five (5) year period, SIC shall give Purchaser sixty (60) days prior
notice before destroying any of such books and records, and Purchaser may at
any time during such sixty days take possession, at Purchaser's cost, of such
books and records, provided that if Purchaser does not take possession of any
of such books and records during such sixty days, SIC shall be free thereafter
to dispose of such books and records.

         Section 12.11.B  Post-Closing Access to Books and Records by SIC.  For
a period of five (5) years after the Closing Date, subject to reasonable
advance notice of time and purpose and to the execution by SIC of reasonable
confidentiality undertakings, SIC and its authorized representatives may at
SIC's expense have reasonable access during normal  business hours to the books
and records related to the Property that are included in the Property and
Purchaser will furnish to SIC such additional information and will cooperate
with SIC in such other





                                      57

respects as SIC may reasonably request, to the extent that such access and
disclosure of such information and cooperation are required by SIC for
financial 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 Authorities, so long as such disclosure,
access, and cooperation do not violate the terms of any agreement to which
Purchaser is bound or any Applicable Law or result in the loss of any
attorney-client or work product privilege.  Purchaser will use reasonable
efforts in accordance with Purchaser's normal record maintenance procedures to
keep and maintain all books and records transferred to Purchaser hereunder for
a period of five (5) years from the Closing or longer as may be required by
statute, except that notwithstanding any requirements of Purchaser's normal
record maintenance procedures, Purchaser shall not destroy such books and
records during such five (5) year period.  From and after such five (5) year
period, Purchaser shall give SIC sixty (60) days prior notice before destroying
any of such books and records, and SIC may at any time during such sixty days
take possession, at SIC's cost, of such books and records, provided that if SIC
does not take possession of any of such books and records during such sixty
days, Purchaser shall be free thereafter to dispose of such books and records.

assessments for which SIC is liable, water, sewer and utility charges, normal
operating expenses, annual permit or inspection fees (calculated on the basis
of the period covered), and all other charges and fees customarily prorated and
adjusted in similar transactions shall be prorated at Closing on the basis of a
365-day year.  If any item subject to proration cannot be calculated accurately
on the Closing Date, then such item shall be calculated within thirty (30) days
after the Closing Date and any party owing another party a sum of money based
on such subsequent proration(s) shall promptly pay the sum owed, together with
interest thereon at the rate of seven percent (7%) per annum from the Closing

Party, as appropriate, in accordance with the terms of this Agreement (and
specifically including the indemnification obligations set forth in Article
11).  Guarantor guarantees to SIC and each SIC Indemnified Party the
performance of all of Purchaser's obligations, liabilities, covenants and
agreements (and specifically the indemnification obligations set forth in
Article 11) to SIC or each SIC Indemnified Party, as appropriate.  Guarantor
agrees to indemnify and hold SIC and each SIC Indemnified Party harmless from
and against all liability and expense, including reasonable attorneys' fees,
sustained by SIC or any SIC Indemnified Party by reason of the failure of the
Purchaser to fully perform and comply with the terms and obligations of this
Agreement.  Guarantor expressly waives any right to require SIC or any SIC
Indemnified Party to bring any action, or exhaust its rights, against Purchaser
or any other person, or to require that resort be had to any assets of
