and  (iii),  for  such  violations,   breaches,  conflicts,  defaults  or  other
occurrences which,  individually or in the aggregate,  would not have a Material
Adverse  Effect or would not prevent the  consummation  of this Agreement or the
Transactions.

      3.4 INVESTMENT INTENT.

            The Interest being acquired in connection  with the  Transactions is
being acquired for Touchstone  Louisiana's  own account for investment  purposes
only and not with a view to, or with any present  intention of,  distributing or
reselling any of such Interest.  Touchstone  Louisiana  acknowledges  and agrees
that the Interest has not been registered  under the Securities Act or under any
state securities laws, and that the Interest may not be, directly or indirectly,
sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed

                                       4

of without registration under the Securities Act and applicable state securities
laws,  except  pursuant  to  an  available  exemption  from  such  registration.
Touchstone  Louisiana also  acknowledges and agrees that neither the SEC nor any
securities  commission  or other  Governmental  Authority  has (a)  approved the
transfer of the  Interest or passed upon or endorsed  the merits of the transfer
of the  Interest,  this  Agreement or the  Transactions;  or (b)  confirmed  the
accuracy of, determined the adequacy of, or reviewed this Agreement.  Touchstone
Louisiana has such knowledge,  sophistication  and experience in financial,  tax
and business  matters in general,  and  investments in securities in particular,
that it is capable of evaluating the merits and risks of this  investment in the
Interest,  and Touchstone  Louisiana has made such  investigations in connection
herewith  as  it  deemed  necessary  or  desirable  so as to  make  an  informed
investment  decision  without  relying  upon  Endeavour  for legal or tax advice
related to this investment. Touchstone Louisiana and each of its stockholders is
an  "accredited  investor"  within  the  meaning  of  Section  2(a)(15)  of  the
Securities Act.

      3.5 BROKERS AND FINDERS FEES.

employees  or  managers  has  employed  any  broker or finder  or  incurred  any
liability  for any  investment  banking fees,  brokerage  fees,  commissions  or
finders fees in connection with the Transactions for which Touchstone  Louisiana
has or could have any liability.

under the laws of its jurisdiction of its organization, with the corporate power
and  authority to own and operate its business as  presently  conducted,  except
where the failure to be or have any of the  foregoing  would not have a Material
Adverse  Effect.  Endeavour is duly qualified as a foreign  corporation or other
entity to do business  and is in good  standing in each  jurisdiction  where the
character  of its  properties  owned or held  under  lease or the  nature of its
activities makes such qualification necessary, except for such failures to be so
qualified or in good standing as would not have a Material Adverse Effect.

      4.2 AUTHORIZATION; VALIDITY AND EFFECT OF AGREEMENT.

            Endeavour  has  the  requisite  corporate  power  and  authority  to
execute,  deliver  and  perform  its  obligations  under this  Agreement  and to

Endeavour and the performance by Endeavour of its obligations  hereunder and the
consummation  of the  Transactions  have been duly  authorized  by all necessary
corporate  action on the part of Endeavour and no other corporate  action on the
part of Endeavour is necessary to authorize this Agreement and the Transactions.

and,  assuming that it has been duly  authorized,  executed and delivered by the
other  parties  hereto,  constitutes  a legal,  valid and binding  obligation of
Endeavour,  in accordance with its terms,  subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization,  moratorium and other similar
laws relating to or affecting  creditors'  rights  generally,  general equitable
principles  (whether  considered  in a  proceeding  in  equity or at law) and an
implied covenant of good faith and fair dealing.

      4.3 NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

partner  of  the  Partnership  and  the  delivery  of  the  adoption  agreement,
assignment  of  partnership  interest and power of attorney set forth in Section
2.2: (i) conflict with Endeavour's  Articles of  Incorporation  or Bylaws;  (ii)

any  provision  of, or result in the  termination  of, the  acceleration  of the
maturity  of,  or the  acceleration  of the  performance  of any  obligation  of
Endeavour,  or  result  in the  creation  or  imposition  of any  Lien  upon any
properties,  assets or business of Endeavour under, any material contract or any
order, judgment or decree to which Endeavour is a party or by which it or any of
its assets or properties is bound or encumbered  except,  in the case of clauses
(ii) and (iii),  for such  violations,  breaches,  conflicts,  defaults or other
occurrences which,  individually or in the aggregate,  would not have a material
adverse effect on its obligation to perform its covenants under this Agreement.

      4.4 TITLE TO INTEREST.

            Endeavour has good and  marketable  title to the Interest and is the
sole record and beneficial  owner of the Interest,  free and clear of any Liens.
With the exception of this Agreement and the Partnership Agreement, there are no
outstanding options, warrants, agreements,  conversion rights, preemptive rights
or other rights to purchase or otherwise acquire the Interest, nor are there any
obligations of any Person to purchase, redeem or otherwise acquire the Interest.
There  are no voting  trusts  or other  agreements  or  understandings  to which
Endeavour  is a party with respect to the voting of the  Interest,  nor is there
any  indebtedness of Endeavour  issued and  outstanding  that has general voting
rights with respect to the Interest.

      4.5 BROKERS AND FINDERS.

            Neither Endeavour nor any of its officers,  directors,  employees or
managers has employed  any broker or finder or incurred  any  liability  for any

                                CERTAIN COVENANTS

      5.1 ACCESS TO INFORMATION.

            At all  times  prior to the  Closing  and in each  case  subject  to

other  party's  authorized  representatives)  reasonable  access  during  normal
business  hours and upon  reasonable  prior notice to the premises,  properties,
books, records, assets, liabilities, operations, contracts, personnel, financial
information  and  other  data  and  information  of or  relating  to such  party
(including  without   limitation  all  written   proprietary  and  trade  secret
information and documents,  and other written information and documents relating

that no such access need be granted to privileged  information or any agreements
or documents subject to confidentiality agreements.

      5.2 CONFIDENTIALITY; NO SOLICITATION.

            (a)  Confidentiality.  Each party  shall  hold,  and shall cause its

be disclosed by the parties; or (iv) is disclosed with the express prior written
consent  thereto of the other party.  The parties shall  undertake all necessary
steps to ensure that the secrecy and confidentiality of such information will be

Notwithstanding  anything contained herein to the contrary, in the event a party
is  required  by court  order  or  subpoena  to  disclose  information  which is
otherwise   deemed  to  be  confidential  or  subject  to  the   confidentiality
obligations hereunder, prior to such disclosure, the disclosing party shall: (i)
promptly notify the  non-disclosing  party and, if having received a court order
or  subpoena,  deliver  a copy of the  same to the  non-disclosing  party;  (ii)
cooperate with the  non-disclosing  party, at the expense of the  non-disclosing
party,  in  obtaining  a  protective  or  similar  order  with  respect  to such
information; and (iii) provide only that amount of information as the disclosing
party is advised by its counsel is necessary to strictly  comply with such court
order or subpoena.

                                   ARTICLE VII

                                 INDEMNIFICATION

      7.1 INDEMNIFICATION BY THE PARTIES.

            From and after the Closing Date, Endeavour or Touchstone  Louisiana,
as the  case  may be (the  "Indemnitor"),  shall  indemnify  and  hold  harmless
Touchstone  Louisiana or Endeavour,  as the case may be (the "Indemnitee"),  and
its respective  officers and directors (the Indemnitee and each such officer and
director an "Indemnified Party"), from and against any and all demands,  claims,
actions  or causes  of  action,  judgments,  assessments,  losses,  liabilities,
damages or penalties and reasonable  attorneys'  fees and related  disbursements
(collectively,  "Claims")  suffered by such Indemnified  Party resulting from or
arising out of (i) any inaccuracy in or breach of any of the  representations or
warranties made by the Indemnitor  herein,  in any certificate,  or in any other
document  delivered  herewith or otherwise required hereby at the time they were
made, and, except for representations and warranties that speak as of a specific
date or time (which  need only be true and correct as of such date or time),  on
and as of the Closing Date, (ii) any breach or  nonfulfillment  of any covenants
or agreements made by the Indemnitor,  and (iii) any  misrepresentation  made by
the Indemnitor, in each case as made herein or in the Exhibits annexed hereto or
in any closing  certificate,  schedule or any  ancillary  certificates  or other
documents or  instruments  furnished  by the  Indemnitor  pursuant  hereto or in
connection with the Transactions.

      7.2 INDEMNIFICATION PROCEDURES FOR THIRD-PARTY CLAIMS.

            (a) Upon obtaining Knowledge of any Claim by a third party which has
given  rise to, or is  expected  to give  rise to, a claim  for  indemnification
hereunder,  the Indemnitee shall give written notice ("Notice of Claim") of such
claim  or  demand  to the  Indemnitor,  specifying  in  reasonable  detail  such
information   as  the   Indemnified   Party  may  have  with   respect  to  such
indemnification  claim  (including  copies of any  summons,  complaint  or other
pleading  which  may have  been  served  on it and any  written  claim,  demand,
invoice, billing or other document evidencing or asserting the same). Subject to
the limitations  set forth in Section 7.2(b) hereof,  no failure or delay by the
Indemnitee in the performance of the foregoing shall reduce or otherwise  affect
the  obligation of the  Indemnitor to indemnify and hold the  Indemnified  Party
harmless,  except to the extent that such  failure or delay shall have  actually
adversely affected Indemnitor's ability to defend against, settle or satisfy any
Claims for which the Indemnified Party entitled to indemnification hereunder.

      (b) If the claim or demand set forth in the  Notice of Claim  given by the
Indemnitee  pursuant to Section 7.2(a) hereof is a claim or demand asserted by a
third party, the Indemnitor shall have fifteen (15) days after the date on which
Notice of Claim is given to notify the  Indemnitee in writing of its election to
defend such third party claim or demand on behalf of the  Indemnified  Party. If
the Indemnitor elects to defend such third party claim or demand, the Indemnitee
shall make available to the Indemnitor  and its agents and  representatives  all
records and other materials that are reasonably  required in the defense of such

                                       11
<PAGE>

third party claim or demand and shall  otherwise  cooperate with, and assist the
Indemnitor  in the defense of, such third party claim or demand,  and so long as
the  Indemnitor  is  defending  such  third  party  claim  in  good  faith,  the
Indemnified  Party shall not pay, settle or compromise such third party claim or
demand. If the Indemnitor elects to defend such third party claim or demand, the
Indemnified  Party  shall have the right to  participate  in the defense of such
third party claim or demand,  at such  Indemnified  Party's own expense.  In the
event,   however,   that  such  Indemnified  Party  reasonably  determines  that
representation  by counsel to the  Indemnitor  of both the  Indemnitor  and such
Indemnified  Party  could  reasonably  be  expected  to present  counsel  with a
conflict of interest,  then the Indemnified Party may employ separate counsel to
represent or defend it in any such action or proceeding and the Indemnitor  will
pay the fees and expenses of such counsel.  If the Indemnitor  does not elect to
defend  such third  party  claim or demand or does not defend  such third  party
claim or demand in good faith,  the  Indemnified  Party shall have the right, in
addition to any other right or remedy it may have hereunder, at the Indemnitor's
expense, to defend such third party claim or demand; provided, however, that (i)
such  Indemnified  Party shall not have any  obligation  to  participate  in the
defense  of,  or  defend,  any such  third  party  claim or  demand;  (ii)  such
Indemnified  Party's defense of or its  participation in the defense of any such
third  party  claim or  demand  shall  not in any way  diminish  or  lessen  the
obligations of the Indemnitor under the agreements of indemnification  set forth
in this Article VII; and (iii) such  Indemnified  Party may not settle any claim
without the consent of the  Indemnitor,  which consent shall not be unreasonably
withheld or delayed.

            (c) The  Indemnitor  and the  Indemnitee  and the other  Indemnified
Party,  if any,  shall  cooperate  fully in all  aspects  of any  investigation,
defense, pre-trial activities, trial, compromise, settlement or discharge of any
claim in respect of which  indemnity  is sought  pursuant to this  Article  VII,
including,  but not limited  to, by  providing  the other party with  reasonable
access to employees and officers (including as witnesses) and other information.

            (d) Except for third party claims being defended in good faith,  the
Indemnitor shall satisfy its obligations  under this Article VII in respect of a
valid  claim  for  indemnification  hereunder  which  is  not  contested  by the
Indemnitor in good faith in cash within thirty (30) days after the date on which
Notice of Claim is given.

      7.3 INDEMNIFICATION PROCEDURES FOR NON-THIRD PARTY CLAIMS.

            In the event any  Indemnified  Party should have an  indemnification
claim against the Indemnitor  under this Agreement that does not involve a claim
by a third party,  the Indemnified  Party shall promptly  deliver notice of such
claim to the Indemnitor in writing and in reasonable  detail. The failure by any
Indemnified  Party to so notify the Indemnitor  shall not relieve the Indemnitor
from any liability  that it may have to such  Indemnified  Party,  except to the
extent that the Indemnitor has been actually  prejudiced by such failure. If the
Indemnitor  does not notify the  Indemnified  Party within fifteen (15) Business
Days  following  its receipt of such notice that the  Indemnitor  disputes  such
claim,  such  claim  specified  by  the  Indemnitor  in  such  notice  shall  be
conclusively deemed a liability of the Indemnitor under this Article VII and the
Indemnitor  shall pay the amount of such liability to the  Indemnified  Party on
demand,  or in the  case of any  notice  in which  the  amount  of the  claim is
estimated,  on such  later  date  when  the  amount  of such  claim  is  finally
determined.  If the Indemnitor disputes its liability with respect to such claim

                                       12
<PAGE>

in a timely manner,  the Indemnitor and the  Indemnified  Party shall proceed in
good faith to  negotiate a  resolution  of such  dispute  and,  if not  resolved
through negotiations, such dispute shall be submitted to arbitration pursuant to
Section 8.12.

      7.4 LIMITATIONS ON INDEMNIFICATION.

            No  claim  for  indemnification  under  this  Article  VII  shall be
asserted by, and no liability for such indemnify shall be enforced against,  the
Indemnitor  to  the  extent  the  Indemnified  Party  has  theretofore  received
indemnification  or otherwise been compensated for such Claim. In the event that
an  Indemnified  Party shall  later  collect any such  amounts  recovered  under
insurance  policies  with  respect  to any  Claim  for  which it has  previously
received  payments under this Article VII from the Indemnitor,  such Indemnified
Party  shall   promptly  repay  to  the   Indemnitor   such  amount   recovered.
Notwithstanding   the   provisions   of  this   Article   VII,   the  amount  of
indemnification  for which any  Indemnitor  shall be liable  hereunder  shall be
limited to the amount of the Cash  Consideration  and the principal and interest
due and payable under the Note.

      7.5 EXCLUSIVE REMEDY.

            The indemnification  provisions of this Article VII (i) shall be the
exclusive  remedy following the Closing with respect to breaches  thereof,  (ii)
shall apply  without  regard to, and shall not be subject to, any  limitation by
reason  of  set-off,  limitation  or  otherwise  and (iii)  are  intended  to be
comprehensive  and  not to be  limited  by any  requirements  of law  concerning
prominence  of language  or waiver of any legal right under any law  (including,
without  limitation,  rights under any workers  compensation  statute or similar
statute conferring immunity from suit). The obligations of the parties set forth
in this Article VII shall be conditioned upon the Closing having occurred.

                                  ARTICLE VIII

                                  MISCELLANEOUS

      8.1 ENTIRE AGREEMENT.

            This  Agreement and the Schedules  and Exhibits  hereto  contain the
entire  agreement  between the parties and  supercede all prior  agreements  and
understandings,  both written and oral,  between the parties with respect to the
subject matter hereof.

      8.2 AMENDMENT AND MODIFICATIONS.

            This Agreement may not be amended,  modified or supplemented  except

enforcement of any such amendment, modification or supplement is sought.

      8.3 EXTENSIONS AND WAIVERS.

            At any time prior to the Closing, the parties hereto entitled to the
benefits of a term or provision may (a) extend the time for the  performance  of
any of the  obligations  or other  acts of the  parties  hereto,  (b)  waive any

                                       13
<PAGE>

inaccuracies in the  representations  and warranties  contained herein or in any
document,  certificate  or  writing  delivered  pursuant  hereto,  or (c)  waive
compliance  with any  obligation,  covenant,  agreement or  condition  contained
herein.  Any  agreement  on the part of a party to any such  extension or waiver
shall be valid  only if set forth in an  instrument  or  instruments  in writing
signed by the party against whom  enforcement of any such extension or waiver is
sought.  No failure or delay on the part of any party  hereto in the exercise of
any right  hereunder  shall impair such right or be construed to be a waiver of,
or  acquiescence  in, any breach of any  representation,  warranty,  covenant or
agreement.

      8.4 SUCCESSORS AND ASSIGNS.

            This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns,  provided,  however,
that no party  hereto may assign its rights or delegate  its  obligations  under
this  Agreement  without the express  prior  written  consent of the other party
hereto. Except as provided in Article VII, nothing in this Agreement is intended
to confer upon any person not a party hereto (and their  successors and assigns)
any rights,  remedies,  obligations  or  liabilities  under or by reason of this
Agreement.

      8.5 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.

            The  representations  and warranties  contained herein shall survive
the Closing and shall thereupon  terminate  twelve (12) months from the Closing,
except that the  representations  contained in Sections  3.1, 3.2, 3.4, 4.1, 4.2
and 4.4 shall survive indefinitely. All covenants,  conditions,  obligations and
agreements  contained herein which by their terms contemplate  actions following
the  Closing  shall  survive  the Closing and remain in full force and effect in
accordance with their terms.  All other covenants,  conditions,  obligations and
agreements  contained  herein shall not survive the Closing and shall  thereupon
terminate.

      8.6 HEADINGS; DEFINITIONS.

      8.7 SEVERABILITY.

            If any provision of this Agreement or the application thereof to any
Person or circumstance is held to be invalid or unenforceable to any extent, the
remainder of this  Agreement  shall remain in full force and effect and shall be
reformed to render the Agreement valid and enforceable  while  reflecting to the
greatest extent permissible the intent of the parties.

damages would be difficult to determine,  and that the parties shall be entitled

                                       14

inadequacy of money damages as a remedy,  in addition to any other remedy at law
or in equity.

            Whether  or not the  Transactions  are  consummated,  and  except as
otherwise  expressly  set forth  herein,  all legal and other costs and expenses
