                                   ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller  represents and warrants to Purchaser that,  except as set forth
in the Seller's Disclosure Schedule,  attached hereto as Annex II, the following
statements are correct as of the date hereof:

         4.1  Organization  and Good Standing.  The Seller is a corporation duly
organized,  validly  existing,  and in good standing under the laws of Delaware;
and the Business is an operating unit of the Seller which comprises a portion of
Seller.  Seller is  authorized  to conduct its business and is in good  standing
under the laws of each jurisdiction where such qualification is required, except
where the failure to be so qualified  would not have a Material  Adverse Effect.
Seller has the corporate power and authority necessary to own, lease and operate
the Assets and carry on the Business.

         4.2  Authority  and Validity of  Agreements.  Seller has the  corporate
power and authority to execute,  deliver, and perform its obligations under this
Agreement  and the  Ancillary  Agreements  and to  consummate  the  transactions
contemplated hereby and thereby, and such execution, delivery,  performance, and
consummation have been duly authorized by all requisite  corporate action on the
part of Seller. This Agreement has been validly executed and delivered by Seller
and constitutes its legal, valid, and binding obligation, enforceable against it
in accordance with its terms,  subject to the Bankruptcy and Equity  Exceptions.
As of the  Closing,  the  Ancillary  Agreements  will be  validly  executed  and
delivered  by  Seller  and  will  constitute  the  legal,   valid,  and  binding
obligations  of  Seller,   enforceable  against  it  in  accordance  with  their
respective terms, subject to the Bankruptcy and Equity Exceptions.

         4.3  Ownership of the  Business.  Seller is the sole lawful  record and
beneficial  owner of the  Business  and the Assets,  and the Assets are free and
clear of any and all Liens,  other than Liens listed on Schedule 4.3 of Seller's
Disclosure  Schedule.  Seller  has good and  indefeasible  title  to, or a valid
leasehold  or  license  interest  in,  all Assets  used in  connection  with the
Business or necessary to operate the Business as operated immediately before the
Closing  (subject to the  Permits),  free and clear of any and all Liens,  other
than Liens listed on Schedule 4.3 of Seller's Disclosure Schedule. Excluding any
Permits or  Environmental  Permits that Purchaser will need to obtain to operate
the Assets,  the Assets,  together with the services to be provided to Purchaser
by Seller  pursuant to the  respective  Service  Agreements,  are  sufficient to
enable  Purchaser  to conduct the  Business as it has been  conducted  by Seller
during the six-month period immediately prior to the date of this Agreement.

         4.4 Outstanding Rights. Except as set forth on Schedule 4.4 of Seller's
Disclosure Schedule, there are no outstanding rights, convertible, contingent or
otherwise,  to acquire, or any plans,  contracts, or commitments or other rights
providing for the right to acquire,  any of the Assets or the  Business,  or any
portion thereof.  There are no securities  convertible into or exchangeable into
any right to own any of the  Assets or the  Business,  or any  portion  thereof.
There are no voting trusts, proxies,  agreements, or other arrangements relating
to or affecting the Assets or the Business.

                                       12

         4.5  No Violation.  Neither the execution and delivery of, the consum-
mation  of  the  transactions  contemplated  by,  nor  the  performance  of  the

Seller, will:

                  (a) violate the Certificate  of Incorporation or the Bylaws of
         Seller;

                  (b) violate or  constitute or result in a breach of or default

         or refuse to perform it;

                  (c) result in the creation or  imposition of any Lien upon any

approval,  or authorization  of, or filing with, any Governmental  Body or other
Person is required to authorize, or in connection with, the execution, delivery,
or performance of, or the consummation of the transactions contemplated by, this
Agreement or the Ancillary Agreements by Seller.

all accounts  receivable  arising on or before the Closing Date will arise, only
from bona fide  transactions  in the Ordinary  Course of  Business.  There is no
dispute  as  to  the  validity  or  collectability  of  such  Acquired  Accounts
Receivable,  and none of the Acquired  Accounts  Receivable has been assigned or

any Liabilities of the Seller related to the Business.

                            COVENANTS OF THE PARTIES

         6.1      Operations; Other Pre-Closing Matters.

                  (a) Operation of the Business. Seller agrees that,  until (and
         including) the Closing, unless Purchaser otherwise agrees in writing,
         Seller shall:

                           (i)  operate the Business only in the Ordinary Course
                  of Business; and

                           (ii) use commercially  reasonable efforts to preserve
                  the current  organization of the Business intact, and preserve
                  the present  relationships  of the  Business  with  employees,
                  customers, and all other Persons having business dealings with
                  the Business.

                  (b) Access.  From the date hereof until the earlier of (i) the
         Closing Date or (ii) the  termination of this  Agreement,  Seller shall
         furnish to Purchaser and its representatives  all information  relating
         to the  Assets and  Business  reasonably  requested  by  Purchaser  and
         provide access to any Asset that  Purchaser may  reasonably  request at
         such  times  as  shall  mutually  be  agreed  on by  the  Parties.  Any
         confidential  information  furnished to Purchaser or made available for
         visual inspection shall be subject to the confidentiality provisions of
         Section  6.11  hereof,  which  shall  survive any  termination  of this
         Agreement.

                  (c) Permits and Consents.  Until (and  including) the Closing,
         and after the Closing  (to the extent  necessary),  the Parties  shall,
         jointly and severally,  use commercially  reasonable  efforts to obtain
         all  Environmental  Permits  and  Permits,  consents,   approvals,  and
         authorizations from, and make all filings with, all Governmental Bodies

                                       21

<PAGE>

         and  other  Persons  as may be  required  for  them to  consummate  the
         transactions  contemplated by this Agreement;  provided,  however, that
         Seller  shall  not be  required  to incur  out of  pocket  expenses  in
         assisting Purchaser in obtaining the Environmental Permits and Permits.

                  (d) Tangible Personal  Property Leases.  Until (and including)
         the Closing,  the Parties shall promptly apply for and use commercially
         reasonable  efforts  to obtain  assignments  of all  tangible  personal
         property leases on the Assets,  from all Persons as may be required for
         them to consummate the  transactions  contemplated  by this  Agreement,
         including, without limitation, assignments of all vehicle and equipment
         leases to which the  Seller  is a party on  behalf of the  Business  or
         which are used in connection with the Business.

                  (e) Intangible  Personal  Property.  Until (and including) the
         Closing,  the Parties shall,  jointly and severally,  use  commercially
         reasonable  efforts to obtain  assignments of all  Intangible  Personal
         Property  and third party  licenses to which  Seller,  on behalf of the
         Business, is a party, or used in connection with the Business, from all
         Persons as may be  required  for them to  consummate  the  transactions
         contemplated by this Agreement.

                  (f) Conditions of Closing.  Until (and including) the Closing,
         Seller and Purchaser shall use their best efforts to satisfy,  or cause
         to be satisfied,  all of the conditions to such Party's  obligations to
         consummate the transactions contemplated by this Agreement set forth in
         Articles VII and VIII, respectively.

         6.2 Environmental Report. Before the Closing, Purchaser may cause to be
prepared at its expense a Environmental  Report on the real properties  owned or
leased by the Seller, or used in the Business, which shall be prepared by a firm
selected by Purchaser  with the consent of Seller  (which  consent  shall not be
unreasonably withheld).  The Environmental Report shall contain such information
as Purchaser deems necessary or advisable and shall be satisfactory to Purchaser
in form and  substance;  however,  the  information  obtained  pursuant  to this
Section  6.2 shall not  include  soil and  ground  water  sampling  unless  such
sampling  is  approved  in  advance  by  Seller.  Seller  agrees  (to the extent
reasonable  and not  financially  burdensome  to  Seller)  to  cooperate  in the
preparation of any such Environmental Report.

         6.3 Identifiable Event. Purchaser shall use its best efforts to prevent
the  occurrence  of  an  Identifiable  Event,  including,   without  limitation,
diligently  maintaining  and inspecting all tanks,  pipelines,  and  containment
structures  according to the standards  identified  in (i) the current  facility
Spill Prevention, Control and Countermeasure ("SPCC") plan, and (ii) in the case
of the Shreveport,  Louisiana and San Antonio, Texas facilities,  the applicable
Facility Response Plan. In the event of the occurrence of an Identifiable Event,
Purchaser shall (a) timely comply with all  requirements of  Environmental  Laws
applicable  to  notification  of and  cooperation  with  Governmental  Bodies in
connection with the release; (b) promptly notify Seller of the release after any
person in charge of Purchaser's  facility  becomes aware of the release,  unless
Seller  becomes aware of any such release prior to  Purchaser's  awareness;  (c)
cooperate  fully  with  Seller  and  Seller's  contractors,  agents,  and  other
representatives  in their conduct of the response to the release pursuant to the
applicable Services Agreement, attached hereto as Exhibit A, for the facility at
or from which the release  took place;  and (d) timely pay all  invoices due and
satisfy  all  other  obligations  under the  applicable  Services  Agreement  in
connection with the release.

         6.4 Approval. Before the Closing, Seller and Purchaser agree to approve
and  adopt  this  Agreement,  the  Ancillary  Agreements  and  the  transactions
contemplated hereby and thereby, in accordance with their respective Certificate
of Incorporation or Articles of Incorporation and Bylaws.

         6.5      Expenses; Taxes.

                  (a)  Whether  or not  the  transactions  contemplated  by this
         Agreement are consummated, each of the Parties shall be responsible for
         all of the  costs  and  expenses  incurred  by  such  Party,  including
         brokerage,  accounting  and legal  expenses,  in  connection  with this
         Agreement and the transactions contemplated hereby; provided,  however,
         that costs and expenses  associated with the Audit shall be apportioned
         equally pursuant to Section 3.10 hereof.

                  (b)  Notwithstanding  Section  6.5(a),  if  the  transactions
         contemplated  by  this  Agreement  are  consummated:

                           (i) Seller and  Purchaser,  respectively,  shall each
                  bear and be liable  for  one-half  of the amount of any sales,
                  use,  or other  transfer  Tax that is imposed or  incurred  in
                  connection   with   this   Agreement   and  the   transactions
                  contemplated  hereby.  To the extent allowed by governing law,
                  Seller and Purchaser, respectively, shall each pay directly to
                  the relevant  jurisdiction  imposing such Tax its share of any
                  such Tax  liability.  If  applicable  law requires  Seller (or
                  Purchaser,  as the case may be) to make  payment  for the full
                  amount  of such Tax  liability  directly  to the  jurisdiction
                  imposing  such Tax , then  Purchaser  (or  Seller)  shall make
                  payment of its allocable share of such Tax liability to Seller
                  (or  Purchaser)  and then  Purchaser  (or  Seller)  shall make
                  payment  of the  full  amount  of such Tax  liability  to such
                  jurisdiction.

                           (ii) To the extent allowed by applicable  law, Seller
                  shall have sole  responsibility  for  preparing and filing all
                  sales,  use,  and  other  transfer  Tax  Returns  required  in
                  connection   with  the   transactions   contemplated  by  this
                  Agreement.   Purchaser   agrees  to   cooperate   and  provide
                  information   reasonably  requested  by  Seller  necessary  to
                  preparing  and  filing  such  Tax  Returns.   If  required  by
                  applicable  law,  Purchaser  shall  join  in  the  filing  and
                  execution  of such Tax  Returns  and/or  shall  file  such Tax
                  Returns.

                           (iii) Except for the Taxes and Tax Returns  described
                  in Sections  6.5(b)(i) or (ii), Seller shall (A) be liable for
                  Taxes  (if any)  related  to the  Assets  for all Tax  periods
                  ending  on or prior  to the  Closing  Date  and (B) have  sole
                  responsibility  for  preparing  and filing all Tax Returns (if
                  any)  required to be filed in  connection  with Taxes (if any)
                  related to the Assets for all Tax  periods  ending on or prior
                  to the  Closing  Date.  Except  for the Taxes and Tax  Returns
                  described in Sections  6.5(b)(i) or (ii),  Seller shall (A) be
                  liable for Taxes  related  to the  Assets for all Tax  periods
                  beginning  on or after  the  Closing  Date  and (B) have  sole


                                       23

<PAGE>

                  required to be filed in  connection  with Taxes related to the
                  Assets for all Tax periods  beginning  on or after the Closing
                  Date.  The parties agree to cooperate and provide to the other
                  information  reasonably  requested  necessary to preparing and
                  filing Tax Returns described in this Section 6.5(b)(iii).

         6.6 Taxable Event. Seller and Purchaser agree to treat the transactions
consummated  pursuant to this  Agreement as a purchase of the Assets  subject to
applicable Taxes, provided, however, to the extent a provision of applicable law
exempts such purchase from Tax or reduces the amount of Tax liability that would
otherwise be payable on such purchase,  Seller and Purchaser  agree to treat the
transactions  in the manner  necessary to take  advantage  of such  exemption or
reduction in Tax liability.

         6.7 Accounts Receivable.  Any Acquired Accounts Receivable collected by
Seller after  Closing  shall be remitted to Purchaser  within ten (10)  Business
Days following such collection. In the event that Seller receives any payment of
accounts receivable, a portion of which is attributable to the Business,  Seller
shall  apportion  such  part of its  accounts  receivable  which  relate  to the
Business and forward such amount to Purchaser pursuant to this Section 6.7.

         6.8 Notice of  Material  Change.  Prior to the  Closing,  Seller  shall
inform Purchaser, and Purchaser shall inform Seller, promptly in writing, of any
change of which  either of them become  aware  which  could  cause that  Party's
representations  and warranties  herein to become false in any material respect.
Notwithstanding  the  foregoing  sentence,  any such notice shall not prevent or
cure any  breach  of the  Parties'  respective  representations  and  warranties
contained in this Agreement, nor shall any such notice amend Seller's Disclosure
Schedule or Purchaser's Disclosure Schedule.

         6.9  Exclusivity.  Unless and until this  Agreement  is  terminated  in
accordance with its terms without any breach by Seller, Seller may not, and will
not permit the Business to, directly or indirectly seek, solicit,  encourage, or
consider indications of interest, or offers from, or negotiate or enter into any
agreements or arrangement  with, any Person with respect to any sale or transfer
of  any  of the  Assets  or  the  Business,  or  any  merger,  consolidation  or
acquisition  that  is in  any  case  inconsistent  with  this  Agreement  or the
transactions  contemplated  hereby.  Seller  will not,  and will not  permit the
Business to,  approve any such  inconsistent  transaction.  Seller will promptly
notify Purchaser of any proposal,  offer, inquiry, or contact by any Person with
respect to any such inconsistent transaction.

         6.10 Retention of Records After the Closing. Seller shall retain copies
of all books and  records  relating  to the  Assets and the  Business  up to the
Closing Date for the period required by applicable law or regulatory  authority,
and shall permit Purchaser and its authorized representatives to have reasonable
access to such copies of books and records to the extent reasonably requested by
Purchaser,  for the  purpose  of (i)  preparing,  filing,  or  amending  any Tax
Returns,  (ii)  investigating  or  defending  any claim made  against any of the
Assets, or (iii) responding to any inquiry, audit, or review by any Governmental
Body of any of the Assets before the Closing.

         respective  Affiliates  which is  disclosed  to the other  Party or its
         legal counsel,  accountants,  representatives or financial institutions

         the Ancillary Agreements and shall hold in confidence and will not use,
         duplicate, reproduce, distribute, disclose or otherwise disseminate any
         Disclosed  Information.  If either Party determines that it is required
         by law to disclose any Disclosed Information,  such Party will not make
         any such  disclosure  unless (and then only to the extent  that) it has
         been  advised by  independent  legal  counsel that such  disclosure  is
         required  by law and then only  after at least ten (10)  Business  Days
         prior  written  notice is given to the Party with  respect to which the
         information is to be disclosed that such  disclosure has been requested
         and is  required  by law.  Following  the  Closing,  nothing  herein is
         intended to restrict the use or  disclosure  of  Disclosed  Information
         that has been or would be  disclosed  to third  parties in the Ordinary
         Course of Business.

                  (c) Press Release and  Announcement.  No press release related
         to this Agreement or the  transactions  contemplated  hereby,  or other
         general  announcement will be issued without the joint written approval
         of  Purchaser  and Seller,  except any public  disclosure  which either
         Party in good faith  believes is required by applicable  securities and
         other laws,  or by the rules of any national  market or stock  exchange
         having  jurisdiction  over the  disclosing  Party or its Affiliates (in
         which  case the Party  desiring  to make the  disclosure  will,  to the
         extent  reasonably  practicable,  consult with the other Party prior to
         making such disclosure).

         6.12     Employee Matters.

                  (a)  Potential  Employment  of  Employees.  Seller  agrees  to
         cooperate with Purchaser and give Purchaser reasonably requested access
         to employees for  interviewing,  completing  applications and forms and
         assistance with employee  communications in connection with Purchaser's
         potential  employment of employees of the Business whom  Purchaser,  in
         its sole discretion,  desires to consider for potential employment with
         Purchaser. Seller will make available to Purchaser reasonably requested
         personnel  reports,  including  a list of current  employees  and their
         dates of hire,  current  position,  salary grades,  salary and training
         records.

                  (b) No  Requirement  to  Hire.  Purchaser  shall  be  under no
         obligation to (i) hire any employees of the Business; (ii) maintain any
         employee  which  Purchaser does hire at the same  position,  title,  or

                                       25

<PAGE>

         level or  responsibility  that  such  employee  had with  Seller or the
         Business;  (iii) grant  seniority  or service  credit to any such hired
         employee;  or (iv) pay any specified  level of compensation or benefits
         to any such hired  employee.  Purchaser  shall, as soon as practicable,
         identify the employees it desires to hire, and the employees  Purchaser
         does not desire to hire.  Purchaser  shall inform  Seller in writing of
         its decision with respect to each  employee of the Business,  including
         their proposed job title, salary and benefits.

                  (c)  Termination  and  Severance.  Prior to the Closing  Date,
         Seller may, with  Purchaser's  approval,  terminate the services of any
         employee whom Purchaser has informed  Seller in writing that it decided
         not to offer  employment.  Purchaser and Seller shall agree as to share
         any severance payments associated with the termination of the employees
         whom  Purchaser  decides  not to  hire  on an  equal  basis,  provided,
         however, that Purchaser's contribution to such severance payments shall
         not exceed $400,000.00.  In the event Purchaser offers employment to an
         employee  of Seller and such  offer is  accepted  so that the  employee
         becomes an employee of the  Purchaser,  and  thereafter  the  Purchaser
         terminates such former employee of Seller for any reason other than for
         cause  during the period of twelve (12) months  after  Purchaser  hires
         such former employee of Seller, then Purchaser agrees to provide Seller
         with  records and reports  relating to the  termination  of such former
         employee  within the twelve (12)  months so that  Seller may  determine
         eligibility of the former employee for severance benefits, if any.

                  (d) Employment  Liabilities.  Purchaser  does not assume,  and
         Seller  hereby   retains,   any  and  all  employment   related  costs,
         obligations,  and liabilities of Seller and the Business, or related to
         the  Business,  incurred  on or prior to  Closing  or which  relate  to
         events, occurrences, conditions, actions, or inactions which took place
         or were in  effect on or prior to  Closing  (whether  or not  reported,
         filed, billed, or paid for on or prior to Closing),  including, without
         limitation,  except as otherwise  provided in this Section 6.12, costs,
         obligations and liabilities  relating to severance  rights of employees
         of Seller or the  Business,  employment  discrimination,  unfair  labor
         practices, wage and hour laws, health and safety, workers compensation,
         wrongful discharge, fringe benefits, insurance, employee benefit plans,
         pensions, retiree medical, vacations,  torts, accidents,  disabilities,
         injuries,  breach of oral or written employment contracts or collective
         bargaining  agreements,  or breach of law, statute,  judgment,  decree,
         injunction,  order,  writ,  rule  or  regulation  of  any  Governmental
         Authority. The entire liability for continuing acts or conditions (such
         as exposure to harmful conditions or continuing  discrimination)  shall
         be assumed by Seller if any  material  portion of the act or  condition
         occurred on or prior to Closing.

                  (e) COBRA and HIPPA.  Seller shall be solely  responsible  for
         any and all liabilities  relating to health care continuation  coverage
         under the Consolidated  Omnibus Budget  Reconciliation  Act of 1985, as
         amended  ("COBRA") and the  portability  requirements  under the Health
         Insurance  Portability and Accountability Act ("HIPPA") with respect to
         employees of the Business  whose  coverage  under Seller's group health
         plan terminates as a result of or in connection  with this  transaction
         or the  events  contemplated  by this  Agreement.  Purchaser  shall  be
         responsible  for  administering  compliance  under  COBRA and HIPPA for


                                       26


<PAGE>

         those  employees  of the  Business who  terminate  subsequent  to their
         becoming   eligible  to  participate  in  the  group  health  plans  of
         Purchaser.

         6.13 SES Texas Right.  Each of Seller and Joe W.  Gillespie owns 50% of
the outstanding  capital stock of SES Texas.  Until  September 30, 2001,  Seller
agrees to use commercially  reasonable efforts (not involving the expenditure of
any sum of money) to obtain the consent of Mr.  Gillespie to the  conveyance  to
Purchaser of Seller's  entire stock  ownership in SES Texas.  If and when Seller
obtains such consent of Mr. Gillespie, Seller agrees to provide Purchaser with a
30-day option to acquire  Seller's entire stock ownership in SES Texas for total
consideration of $1.00. During such 30-day period, Seller shall use commercially
reasonable  efforts  to cause SES Texas to  provide  Purchaser  with  reasonable
access to  information  and  employees of SES Texas  necessary  for Purchaser to
understand  the  business  and  operations  of SES Texas,  subject to  Purchaser
providing  SES  Texas  with  commercially   reasonable  written  assurance  that
Purchaser will hold in confidence all confidential  and proprietary  information
of SES Texas that Purchaser obtains.

         6.14 Cooperation with Services Agreement.  Seller will use commercially
reasonable efforts to assist Purchaser in securing a services agreement with the
current operator of the West Memphis,  Tennessee  facility  formerly operated by
the Business.

                                   ARTICLE IX

                  SURVIVAL OF REPRESENTATIONS; INDEMNIFICATION

         9.1 Survival of  Representations.  All  representations  and warranties
made by any Party in or pursuant to this Agreement shall survive for a period of
18 months  after the  Closing  Date,  except  that (a) the  representations  and
warranties in Section 4.20 (Environmental Matters) shall survive for a period of
three years and (b) the  representation  and  warranties in the first and second
sentences of Section 4.3  (Ownership  of the  Business)  shall survive after the
Closing Date without limitation (to the extent permitted by law).  Purchaser may
rely  on  the   representations  and  warranties  of  Seller,  and  vice  versa,
notwithstanding  any investigation or audit by the relying Party before,  at, or
after the Closing or the decision of the relying Party to effect the Closing.

         9.2      General Indemnities.

                  (a) Subject to the terms and  conditions  of this  Article IX,
         Seller shall indemnify, defend, and hold harmless Purchaser, and any of
         its  officers and  directors,  from and against all Damages that may be
         asserted  against,  resulting to, imposed upon, or incurred by any such
         Person by reason of,  relating to, or resulting  from:  (i) a breach of
         any representation,  warranty, covenant, or agreement of Seller made in
         or  pursuant  to this  Agreement;  (ii) any  Environmental  Claim  with
         respect to the Assets or the  operations  of the Business  that accrued
         prior to the  Closing;  (iii) the  inability of Purchaser to obtain any
         necessary  certificate  of occupancy  with respect to the real property
         upon which any of the Assets are located;  (iv) the violation by Seller
         prior to the Closing of any applicable  zoning or building  regulation,
         ordinance or other law, order,  regulation,  or requirement relating to
         the real property upon which any of the Assets are located;  or (v) the
         failure  of Seller to pay any Tax for  which it bears  liability  under
         Section 6.5.

                  (b) Subject to the terms and  conditions  of this  Article IX,
         Purchaser shall indemnify,  defend, and hold harmless Seller and any of
         its  officers and  directors,  from and against all Damages that may be
         asserted  against,  resulting to, imposed upon, or incurred by any such
         Person by reason of, relating to, or resulting from (i) a breach of any
         representation,  warranty,  covenant, or agreement of Purchaser made in
         or  pursuant  to  this  Agreement;  (ii)  the  violation  of any of the
         Environmental Laws by Purchaser subsequent to the Closing in connection
         with the Business,  including but not limited to Damages resulting from
         violations of any such law by Purchaser  with respect to the use of, or
         activities  conducted on or from,  any such real property by Purchaser,
         including the use by Purchaser of underground storage tanks thereunder,
         subsequent  to the  Closing,  but, in cases where such  violations  are
         caused by a release of a Regulated Substance,  or a release itself is a
         violation,  only to the extent  such  Damages  are  attributable  to an


                                       29

<PAGE>

         Identifiable Event, (iii) an Identifiable Event; or (iv) the failure of
         Purchaser  to pay any Tax for which it bears  liability  under  Section
         6.5.

                  (c) The indemnity provided for in this Section 9.2 shall in no
         event exceed the aggregate amount of the Purchase Consideration.

                  (d) Neither Party shall be liable for  indemnification  claims
         under this Section 9.2 until the  aggregate  amount of  indemnification
         claims hereunder  exceeds Seventy Five Thousand  Dollars  ($75,000.00),
         but upon reaching such amount,  the indemnifying  Party shall be liable
         for all  indemnification  claims in excess  of such  amount;  provided,
         however,  that the provisions of this Section 9.2(d) shall not apply to
         (i) Seller's  indemnities under Section 9.2(a)(v),  and (ii) the breach
         of any covenant or agreement contained in this Agreement.

         9.3  Conditions  of  Indemnification.  The  obligations  of  Seller  or
Purchaser,  as the case may be (the "indemnifying  Party") to other Persons (the
"Party  to  be   indemnified")   with   respect  to  any  claim  or  demand  for
indemnification shall be subject to the following terms and conditions:

                  (a) The Party to be indemnified  shall promptly give notice to
         the  indemnifying  Party of any claim,  whether  between the Parties or
         brought by a third party,  specifying both the basis for and the amount
         of such claim, to the extent specified or otherwise known. If the claim
         or demand for  indemnification  relates to a claim,  action,  suit,  or
         proceeding  asserted or filed by a Third Party  against the Party to be
         indemnified (a "Third-Party Claim"), then such notice shall be given by
         the Party to be indemnified  within twenty (20) days of receipt thereof
         (or such  earlier  time as might be required to avoid  prejudicing  the
         indemnifying  Party's  position).  The  failure  of  the  Party  to  be
         indemnified  to give such notice  shall not  relieve  the  indemnifying
         Party  of  its  obligations   hereunder,   except  to  the  extent  the
         indemnifying Party is actually prejudiced thereby.

                  (b)  Following   receipt  of  notice  from  the  Party  to  be
         indemnified of a claim or demand for indemnification,  the indemnifying
         Party  shall have twenty  (20) days to make such  investigation  of the
         claim or demand as the indemnifying Party deems necessary or desirable.
         For the  purposes of such  investigation,  the Party to be  indemnified
         agrees to make available to the  indemnifying  Party (or its authorized
         representatives)  the  information  relied  upon  by  the  Party  to be
         indemnified  to  substantiate  the claim or demand.  If the Party to be
         indemnified  and  the  indemnifying   Party  agree  at  or  before  the
         expiration of such twenty (20) day period (or any mutually  agreed upon
         extension  thereof) to the validity and amount of such claim or demand,
         then the  indemnifying  Party shall  immediately pay to the Party to be
         indemnified  the full  amount of the claim or demand to the extent that
         such Party to be indemnified is entitled to indemnification pursuant to
         this Section 9.3. If the Party to be indemnified  and the  indemnifying
         Party do not agree  within  such  period (or any  mutually  agreed upon
         extension  thereof),  then the Party to be  indemnified  may  pursue or
         exercise any remedies or rights available to it.

                  (c) After receipt of notice of commencement of any Third-Party
         Claim evidenced by service of process or other legal pleading,  or with
         reasonable  promptness  after any other  assertion  in  writing  of any
         Third-Party   Claim,  the  Party  to  be  indemnified  shall  give  the


                                       30

<PAGE>

         indemnifying  Party written notice thereof together with a copy of such
         claim,  process, or other legal pleading within the period set forth in
         the second  sentence of Section  9.3 (a).  The failure of a Party to be
         indemnified  to give the  indemnifying  Party  such  notice  shall  not
         relieve the  indemnifying  Party of its  obligations  under Section 9.3
         except to the  extent the  indemnifying  Party is  actually  prejudiced
         thereby.  The indemnifying  Party shall have the right to undertake the
         defense,  compromise,  or  settlement  of  the  Third-Party  Claim,  by
         representatives  of its own  choosing and at its own expense so long as
         the  indemnifying  Party agrees to assume and conduct,  and  diligently
         conducts,  such defense (or, if applicable,  compromise or settlement).
         In such  event  the  Party to be  indemnified  may  participate  in the
         defense,  compromise,  or settlement with counsel of its own choice and
         at its own expense.

                  (d) If the  indemnifying  Party,  by the thirtieth  (30th) day
         after receipt of notice of any such claim (or, if earlier, by the tenth
         (10th) day preceding the day on which an answer or other  pleading must
         be served  in order to  prevent  judgment  by  default  in favor of the
         plaintiff),  does not elect to defend such Third-Party  Claim, then the
         Party to be  indemnified  shall have the right (upon further  notice to
         the  indemnifying  Party) to retain  counsel and undertake the defense,
         compromise,  or settlement of such Third-Party  Claim on behalf of, and
         for  the  account  and  risk  of,  the  indemnifying  Party  and at the
         indemnifying Party's expense,  subject to the right of the indemnifying
         Party to participate,  with its own counsel and at its own expense,  in
         the defense,  settlement, or compromise. If the Party to be indemnified
         and the  indemnifying  Party agree at or before the  expiration  of the
         period set forth in this Section  9.3(d) (or any  mutually  agreed upon
         extension  thereof)  to the  validity  and  amount of such  Third-Party
         Claim,  then the indemnifying  Party shall immediately pay to the Party
         to be indemnified the amount so agreed.

                  (e) If there is a  conflict  of  interests  which  renders  it
         inappropriate  for the same counsel to represent both the  indemnifying
         Party and the Party to be  indemnified in defending,  compromising,  or
         settling  a  Third-Party   Claim,  the  indemnifying   Party  shall  be
         responsible  for  paying  for  separate  counsel  for the  Party  to be
         indemnified. In such event, however, if there is more than one Party to
         be  indemnified,  the  indemnifying  Party shall not be responsible for
         paying  for more  than one  separate  counsel  (which  may be a firm of
         attorneys)  to represent the Parties to be  indemnified,  regardless of
         the number of Parties to be indemnified.

                  (f) The indemnifying Party may compromise,  settle, or resolve
         any  Third-Party   Claim  without  the  consent  of  the  Party  to  be
         indemnified if such compromise, settlement, or resolution involves only
         the  payment of money by the  indemnifying  Party  (whether  on its own
         behalf or on behalf of the Party to be  indemnified)  and the  claimant
         provides to the Party to be indemnified a release from all Liability in
         respect  of such  claim.  Otherwise,  the  indemnifying  Party  may not
         compromise,  settle,  or resolve the claim  without  the prior  written
         consent  of the  Party  to be  indemnified,  which  consent  may not be
         unreasonably withheld.

                  (g) The Party to be  indemnified  and the  indemnifying  Party
         must cooperate with all reasonable requests of the other in the defense
         of any Third-Party Claim.

                  (h)  Notwithstanding  anything to the contrary in this Section
         9.3,  with respect to an  obligation  of Seller to indemnify  Purchaser
         pursuant  to Section  9.2(a)  above with  respect to any  Environmental
         Claim that  requires any removal,  remediation,  response,  clean up or
         other corrective action ("Remediation"),  Seller may elect to implement
         and  complete  such  Remediation.  If  Seller  elects  to  conduct  the
         Remediation:

                    (i)  Seller,  in good faith, will coordinate the schedule of
                         the Remediation  with Purchaser so that  disruptions of
                         Purchaser's operations will be minimized;

                    (ii) Seller  will  obtain  the  prior  written  approval  of
                         Purchaser,  which  approval  will  not be  unreasonably
                         withheld,  for any consultant or contractor retained by
                         Seller  to   investigate,   design  or  implement   the
                         Remediation;

                    (iii)Seller will conduct the  Remediation in compliance with
                         all  applicable  federal,  state  and  local  laws  and
                         regulations   and  as  directed   by  the   appropriate
                         Governmental Body; and

                    (iv) Seller will not agree to or select any Remediation that
                         imposes   any   material   obligation   on   Purchaser,
                         including,  without limitation,  the obligation to sign
                         manifests or obtain permits,  without the prior written
                         consent of the  Purchaser,  which  consent shall not be
                         reasonably withheld.

                    (v)  During  the  period  in which  Seller is  conduction  a
                         Remediation pursuant to this Section 9.3(c),  Purchaser
                         shall   provide   Seller   and  its   consultants   and
                         contractors  reasonable access to the affected property
                         for the purpose of conducting activities related to the
                         Remediation, including where necessary the use of heavy
                         equipment.   Any  such  access   shall  be  subject  to
                         reasonable    restrictions    imposed   by   Purchaser,
                         including, without limitation,  restrictions related to
                         worker safety.  Seller shall expeditiously  remove from
                         the  property  all  drill  cuttings,  soil,  debris  or
                         liquids  generated  from  or  in  connection  with  the
                         Remediation  and shall  restore  the  property  and any
                         existing  structures or equipment removed or damaged in
                         the   course  of  the   Remediation   to  a   condition
                         substantially  the same as the  condition  that existed
                         immediately  prior to the Remediation.  Seller or their
                         consultants and contractors  shall provide Purchaser at
                         least five (5) business  days' notice of the activities
                         to be conducted on the property, which notice may be in
                         the form of a schedule of activities.

                    (vi) Seller and Purchaser agree that any  Remediation  shall
                         meet  all  requirements  of the  Governmental  Body  or
                         Bodies   directing  the   Remediation   and  shall  not
                         materially  impede or increase the cost of  Purchaser's
                         business operations on the affected property. Purchaser
                         acknowledges that the Remediation may be a "risk-based"
                         Remediation pursuant to, and consistent with applicable
                         federal,  state and local laws and  regulations,  which
                         may require the  establishment of certain  restrictions
                         or  conditions  affecting  the  property  on which  the
                         Remediation is being conducted. Purchaser agrees not to


                                       32

<PAGE>

                         object  to any  such  "risk-based"  Remediation  unless
                         Purchaser's  agreement will, in the good faith judgment
                         of  Purchaser,  expose  Purchaser to liability to third
                         parties.

                    (vii)Seller   shall   not  take  any   action  or  make  any
                         communication  which  has  a  material  effect  on  the
                         resolution or outcome of any Environmental  Claim which
                         could  lead to the  filing  of an  Environmental  Claim
                         against Purchaser,  without providing at least five (5)
                         business days advance notice (unless otherwise required
                         by law)  to  Purchaser.  Any  material  breach  of this
                         obligation shall relieve Purchaser of Liabilities under
                         this   Agreement   with   respect  to  the   applicable
                         Environmental  Claim to the extent  Purchaser  has been
                         prejudiced  by the lack of timely and adequate  notice.
                         This  notification   requirement  shall  not  apply  to
                         communications  which  are  part  of  or  relate  to  a
                         judicial  or  administrative  proceeding  in which  the
                         Parties are litigating claims against each other.

         9.4      Determination of Damages; Survival of Obligations.

                    (a)  In no event  shall  the  acceptance  by the Party to be
                         indemnified of any money or other  tangible  properties
                         as partial  compensation  or  indemnification  from any
                         source for the amount of its Damages  prevent the Party
                         to  be  indemnified   from  seeking   compensation   or
                         indemnification  from  any  source  for the rest of the
                         entire amount of its or his Damages.

                    (b)  An  indemnifying  Party's  indemnification  obligations
                         shall continue as to any claim or demand  therefor made
                         within  any  applicable  survival  period  even  though
                         Damages  are not  imposed or  incurred  until after the
                         survival period.

                    (c)  The indemnifying  Party's  indemnification  obligations
                         shall survive indefinitely,  to the extent permitted by
                         applicable law, with respect to the following  matters:
                         (i) a  breach  of any  covenant  or  agreement  made in
                         Sections 6.1(c), 6.2 or 6.3 of this Agreement; (ii) the
                         matters   indemnified   in   Sections   9.2(a)(v)   and
                         9.2(b)(iv)  of this  Agreement;  (iii) with  respect to
                         Seller,  the matters  indemnified in Section 9.2(a)(ii)
                         of this Agreement;  and (iv) with respect to Purchaser,
                         the matters indemnified in Section 9.2(b)(ii) and (iii)
                         of this Agreement.

         9.5 Exclusivity of Remedies.  The remedies  provided in this Article IX
are  exclusive  of any other  rights or remedies  available  to a Party or other
Person;  provided,  however,  that with  respect to a breach of any  covenant or
agreement contained in this Agreement,  the remedies provided in this Article IX
are in addition to, and not exclusive of, any other rights or remedies available
to a Party  or  other  Person  and,  provided  further,  that a Party  shall  be
permitted to join the other Party as a party to any action  initiated by a third
party,  if the subject  matter of such action is subject to  indemnification  by
such other Party under this Agreement.

         eliminated) by Purchaser, on or before September 30, 2000;

                  (b) by Purchaser,  if the  conditions set forth in Article VII

         or if  Purchaser  has  made  any  material  misrepresentation  in  this
         Agreement  (unless  such  event has been  caused by the  breach of this
         Agreement by the Party seeking such termination);

                  (d) by  Purchaser,  if there  has been a  material  breach  by

the transactions  contemplated by this Agreement,  and no Party shall retain any
copies, extracts or other reproductions,  in whole or in part, of such Disclosed
Information;  provided,  however,  that with respect to any  analyses,  studies,

be binding  upon the  Parties  and their  respective  successors  and  permitted
assigns. Nothing in this Agreement,  expressed or implied, is intended to confer

         11.9  Severability.  If any  provision of this  Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term hereof,  such  provision  shall be fully  severable  and the  remaining
provisions  hereof  shall  remain  in full  force  and  effect  and shall not be
affected  by  the  illegal,  invalid,  or  unenforceable  provision  or  by  its
severance.  Furthermore,  in lieu of such  illegal,  invalid,  or  unenforceable
provision,  there  shall be  added as part of this  Agreement,  a  provision  as
similar in its terms to such illegal, invalid, or unenforceable provision as may
be possible and be legal, valid, and enforceable.

4.11):

                  (a) a Person shall be deemed to have  "knowledge"  of a parti-

         11.11  Entire Agreement.  This Agreement and its Annexes and Schedules,
including the Ancillary  Agreements and the documents executed at the Closing in

inducement, or statement of intention has been made by either Party which is not
