any optional  payment on the Base Rate Loan,  and three Business Day's notice in
advance of any  prepayment on the LIBOR Rate Loan  required  pursuant to Section
3.4.  Such notices  shall  specify what portion of the Loan is to be prepaid and
the date of prepayment.  Such notices shall be  irrevocable  by Borrower.  As of

shortest Interest Periods remaining.

accrued, unpaid interest, shall be due and payable.

(c)  Interest on the Loan shall  accrue daily and shall be computed on the basis
of a year of 365 or 366 days, as appropriate, for Base Rate Loans, and a year of
360 days for LIBOR Rate Loans. Interest on the Loans shall be payable in arrears

overdue  principal,  and (to the extent  permitted under applicable law) overdue

without  set-off or  counterclaim or deduction of any kind. If any payment to be
made by  Borrower  hereunder  or under the Note shall  become due on a day other
than a Business Day, such payment shall be made on the next succeeding  Business
Day and such  extension of time shall be included in computing  any interest and
fees in respect of such payment, unless the result of such extension would be to
carry any Interest  Period  relating to a LIBOR Rate Loan into another  calendar
month in which event such Interest Period shall end on the immediately preceding
Business Day.

2.9 - Origination  Fee. Upon execution of this Agreement and the Note,  Borrower
shall pay to Lender an origination fee in the amount of $15,000.00  (referred to

Lender a redetermination  fee in the amount of one-half of one percent (0.5%) of
the amount of the requested increase (referred to herein as the "Redetermination
Fee").  The  parties   specifically  agree  that  the  Borrower  shall  pay  the
Redetermination  Fee to  Lender  regardless  of  whether  Lender  agrees  to the

3.1 - Borrowing Base . The term  "Borrowing  Base" shall refer to an amount that

ownership interests of the Borrower in the Mortgaged Properties that are subject

permitted under the Loan Agreement.  The Borrowing Base under the Loan is set at
the sum of $18,000,000.00. The Borrowing Base shall reduce on a monthly basis by

redetermining the Borrowing Base, Lender shall determine the loan value which it
assigns to the oil and gas properties  that are proven  reserves,  developed and
producing  and that are  covered  by the Deeds of  Trust.  As to the oil and gas
properties,  the loan value  shall be based on Lender's  engineering  evaluation
which  utilizes  Lender's then current  policy for oil and gas prices,  discount
factors, coverage percentage and appropriate risk factors.

3.4 - Mandatory  Increase in  Collateral or Prepayment of Principal of the Note.
In the event that the unpaid principal balance of the Note shall, at the time of

Commitment,  Lender,  acting in its sole  discretion,  may  require  Borrower to
either,   (i)  within  ten  (10)  business  days   thereafter,   by  instruments
satisfactory  in form and substance to Lender,  provide  Lender with  additional
Collateral with value in amounts satisfactory to Lender in order to increase the
Borrowing Base by an amount at least equal to such excess;  (ii) within ten (10)
business  days  thereafter,  prepay the  principal  of the Note  (together  with
accrued interest on the principal amount so prepaid) in an amount at least equal
to such excess;  or (iii)  amortize the overage by payments of six equal monthly
installments.

                                   ARTICLE IV
                         YIELD PROTECTION AND ILLEGALITY

4.1 - Illegality.

(a) If  Lender  shall  determine  that  the  introduction  of any  law,  rule or
regulations,   or  any  change  in  any  law,  rule  or  regulation  or  in  the
interpretation  or  administration  thereof,  has made it unlawful,  or that any
central bank or other  governmental  authority has asserted that it is unlawful,
for  Lender to make  LIBOR  Rate  Loans,  then,  on notice  thereof by Lender to
Borrower,  the  obligation of Lender to make LIBOR Rate Loans shall be suspended
until Lender shall have notified Borrower that the circumstances  giving rise to
such determination no longer exist.

(b) If Lender  shall  determine  that it is unlawful to maintain  any LIBOR Rate
Loan,  and,  if any LIBOR Rate  Loans are then  outstanding,  Lender  shall give
notice thereof to Borrower, and within three Business Days after receipt of such
notice Borrower shall elect either (A) to prepay in full all LIBOR Rate Loans of
Lender then outstanding,  together with interest accrued thereon,  either on the
last day of the  Interest  Period  thereof if Lender may  lawfully  continue  to
maintain  such LIBOR Rate Loans to such day, or  immediately,  if Lender may not
lawfully  continue to maintain such LIBOR Rate Loans,  together with any amounts
required to be paid in connection  therewith pursuant to this Agreement,  or (B)
to  immediately  convert such LIBOR Rate Loans to Base Rate Loans in  accordance
with Article II of this Agreement.

(c) If the  obligation  of Lender to make or maintain  LIBOR Rate Loans has been
terminated,  Borrower may elect, by giving notice to Lender that all Loans which
would otherwise be made by Lender as LIBOR Rate Loans shall be instead Base Rate
Loans.

4.2 - Increased Costs and Reduction of Return.

(a) If Lender shall determine that, due to either (i) the introduction of or any
change  (other  than any change by way of  imposition  of or increase in reserve
requirements  included  in the  calculation  of  the  LIBOR  Rate)  in or in the
interpretation  of any  law or  regulation  or  (ii)  the  compliance  with  any
guideline,  or request  from any central  bank or other  governmental  authority
(whether or not having the force of law) issued after  January 31,  1997,  there
shall be any  increase  in the cost to Lender  of  agreeing  to make or  making,
funding or  maintaining  any LIBOR Rate Loans (other than changes in the rate of
taxes on the  overall net income of  Lender),  then Lender  shall give notice of
such determination to Borrower,  and Borrower shall have the option either (iii)
to immediately  convert all  outstanding  LIBOR Rate Loans to Base Rate Loans in
accordance  with Article II or (iv) Borrower shall be liable for, and shall from
time to time,  upon  demand  therefor by Lender,  pay to Lender such  additional
amounts as are  sufficient to compensate  Lender for such  increased  costs.  If
Borrower elects to convert to Base Rate Loans,  it shall  nevertheless be liable
for any increased  costs incurred by Lender  regarding  LIBOR Rate Loans accrued
prior to the date of conversion.

(b) If Lender shall have  determined  that (i) the  introduction  of any capital
adequacy regulation,  (ii) any change in any capital adequacy regulation,  (iii)
any change in the  interpretation  or  administration  of any  capital  adequacy
regulation by any central bank or other governmental  authority charged with the
interpretation  or administration  thereof,  or (iv) compliance by Lender or any
corporation  controlling  the  Lender,  with any  capital  adequacy  regulation;
affects  or would  affect  the  amount of capital  required  or  expected  to be
maintained  by Lender or any  corporation  controlling  Lender and (taking  into
consideration  Lender's or such  corporations'  policies with respect to capital
adequacy and Lender's  desired return on capital)  determines that the amount of
such capital is increased as a consequence  of its  commitment to make the Loan,
credits or other obligations under this Agreement, then Lender shall give notice
of such determination to Borrower, and Borrower shall have the option either (v)
to immediately  convert all  outstanding  LIBOR Rate Loans to Base Rate Loans in
accordance  with  Article  II or (vi)  to pay to  Lender,  from  time to time as
specified by Lender, additional amounts sufficient to compensate Lender for such
increase.

4.3 - Funding  Losses.  Borrower  agrees to reimburse  Lender and to hold Lender
harmless  from  any loss or  expense  which  Lender  may  sustain  or incur as a
consequence of:

(a) The  failure of  Borrower to make any  payment or  mandatory  prepayment  of
principal of any LIBOR Rate Loan (including payments made after any acceleration
thereof);

(b) The failure of Borrower to borrow, continue or convert a Loan after Borrower
has  given (or is deemed to have  given) a Request  for  Advance  or a Notice of
Conversion/Continuation;

(c) The failure of Borrower to make any  prepayment  after  Borrower has given a
notice in accordance with Section 2.3;

(d) The prepayment (including pursuant to Section 2.3) of a LIBOR Rate Loan on a
day which is not the last day of the Interest Period with respect thereto; or

(e) The  conversion  pursuant to of any LIBOR Rate Loan to a Base Rate Loan on a
day that is not the last day of the respective  Interest  Period;  including any
such loss or expense  arising  from the  liquidation  or  reemployment  of funds
obtained by it to maintain  its LIBOR Rate Loans  hereunder or from fees payable
to terminate the deposits from which such funds were obtained.

4.4 - Inability to Determine Rates. If Lender shall have determined that for any
reason  adequate and reasonable  means do not exist for  ascertaining  the LIBOR
Rate for any  requested  Interest  Period with respect to a proposed  LIBOR Rate
Loan or that the LIBOR Rate  applicable for any requested  Interest  Period with
respect to a proposed LIBOR Rate Loan does not adequately and fairly reflect, in
Lender's  reasonable  judgment,  the cost to Lender of funding such Loan, Lender
shall forthwith give notice of such determination to Borrower.  Thereafter,  the
obligation of Lender to make or maintain  LIBOR Rate Loans,  as the case may be,
hereunder shall be suspended until Lender revokes such notice in writing, unless
means  exist for  ascertaining  the LIBOR Rate and  Borrower  agrees to pay such
amount as Lender determines in its sole and absolute  discretion is necessary to
reflect the cost of Lender of funding  such Loan.  Upon  receipt of such notice,
Borrower may revoke any Request for Advance or Notice of Conversion/Continuation
then  submitted by it. If Borrower  does not revoke such request or notice prior
to the time that such Loan is made,  Lender shall make,  convert or continue the
Loan, as proposed by Borrower in the amount specified in the applicable  request
or notice  submitted  by  Borrower,  but such Loan shall be made,  converted  or
continued as Base Rate Loans instead of LIBOR Rate Loans.

4.5 - Certificate  of Lender.  If Lender claims  reimbursement  or  compensation
pursuant to this  Article IV,  Lender  shall  deliver to Borrower a  certificate
setting forth in reasonable  detail the amount  payable to Lender  hereunder and
such  certificate  shall be binding on Borrower unless  Borrower  objects to the
contents of such certificate within five Business Days after receipt thereof. If
Borrower objects, Lender and Borrower shall attempt to resolve their differences
within 10 days,  and if  agreement  is not  reached  within such period then all
LIBOR Rate Loans shall be immediately converted to Base Rate Loans.

4.6 - Survival.  The agreements  and  obligations of Borrower in this Article IV
shall survive the payment of all other Obligations.

documents,  accounts  and chattel  paper  arising  from or related to any of the
Collateral.

                                   ARTICLE VI
                              CONDITIONS PRECEDENT

with the requirements hereof.

Interests and other properties shall be valid,  subsisting and in full force and
effect, and all rentals,  royalties and other amounts due and payable in respect

reorganization  or similar laws  affecting  creditors'  rights  generally,  upon
execution,  delivery and recording,  or filing, as appropriate,  the Loan Papers

terms of the Loan Papers cause Borrower to be, in default (nor has any potential
default  occurred)  under any Material  Agreement,  any  agreement,  document or
instrument giving rise to Mineral Interests,  farmout agreements,  gas contracts
or any  operating  or joint  operating,  or  unitization  agreements  related to
Mineral  Interests,  other than in each case such defaults or potential defaults
which could not, individually or collectively,  cause a Material Adverse Change;
and a default by  Borrower  under any  operating  or joint  operating  agreement
related  to any  Mineral  Interests  it owns  will  not  result  in any  loss or
diminution of any other Mineral Interests it owns.

7.10 - ERISA . Borrower has neither  terminated  a plan created  pursuant to the

partnership,  joint venture or association of any type  whatsoever  except those

environmental  law or  regulation  and there has not  heretofore  been filed any
complaint, nor commenced any administrative  procedure,  against Borrower or any
of  its  predecessors,   alleging  a  violation  of  any  environmental  law  or

regular business (oil and gas exploration and  production),  may use or generate
on a portion of its  properties  materials  which are  Hazardous  Materials,  as
hereinafter  defined.  Borrower has and will make a good faith attempt to comply
with all applicable statutes and regulations in the use, generation and disposal
of such  materials.  To the best of its  knowledge,  Borrower has not  otherwise
installed,  used,  generated,  stored or disposed of any hazardous waste,  toxic
substance,  asbestos  or  related  material  ("Hazardous  Materials")  on  their
properties.  For the  purposes  of this  Agreement,  Hazardous  Materials  shall

"hazardous  substances,"  "hazardous waste" or "pollutant or contaminant" in any
other applicable federal, state or local environmental law or regulation. To the
knowledge  of Borrower,  there do not exist upon any property  owned by Borrower
any underground storage tanks or facilities,  and none of such property has ever

writing,  to  Lender  as an  attachment  to this  Agreement;  and  all  writings
heretofore  or  hereafter  exhibited  or  delivered to Lender by or on behalf of
Borrower  are and will be genuine  and in all  respects  what they  purport  and
appear to be.

7.16 - Closing  Compliance . Borrower  represents to the Lender for all purposes
that as of the  date of the  execution  of this  Agreement,  to the  best of its
knowledge,  it is in full and complete compliance with all applicable regulatory

(c) immediately  upon becoming aware of the existence of, or any material change
in the status of, any litigation which could create a Material Adverse Change if

matter;

(d)  immediately  upon becoming aware of an Event of Default or the existence of
any  condition or event that  constitutes,  or with notice or lapse of time,  or
both,  would  constitute an Event of Default,  a verbal  notification  to Lender
specifying the nature and period of existence  thereof and what action  Borrower
is taking or proposes to take with respect thereto and, immediately  thereafter,
a written confirmation to Lender of such matters;

(e)  immediately  upon becoming  aware that any person has given notice or taken
any other action with respect to a claimed default under any material indenture,
mortgage,  deed of trust,  promissory  note,  loan  agreement,  note  agreement,

matters;

Federal Energy Regulatory Commission which does or could result in a claim, fine
or judgment  against  Borrower in excess of $100,000.00 if not paid or otherwise
resolved, a written communication to Lender of such matter; and

(g) such other information as may be reasonably requested by Lender.

true and  correct by the  President  or Chief  Financial  Officer of Borrower by
signature and date thereon.

8.2 - Taxes . Borrower will pay and discharge or cause to be paid and discharged
all taxes,  assessments  and  governmental  charges or levies imposed upon it or
upon its  income and  profits or upon any of its  property,  real,  personal  or
mixed,  or upon any part  thereof,  before the same shall become in default,  as
well as all lawful claims for labor, materials and supplies or otherwise, which,
if not  paid,  might  become a Lien upon such  properties  or any part  thereof;
provided that unless any governmental  entity has threatened  seizure or sale of
any Collateral of Borrower for failure to pay any such tax, assessment,  charge,
levy, or claim,  Borrower shall not be required to pay and discharge or cause to
be paid or discharged any such tax, assessment,  charge, levy or claim contested
by it in good  faith by  appropriate  proceedings.  If,  however,  Borrower  has
received  notice of a threatened  seizure or sale of any  Collateral of Borrower
from any governmental  entity, the preceding provision shall be inapplicable and
Borrower shall be required to tender payment under protest to that  governmental
entity before such sale or seizure takes place.

8.3 - Discharge of Contractual  Obligations . Borrower will do and perform every
act and discharge all of the obligations provided to be performed and discharged
under the Loan Papers,  and any and all of the instruments or documents referred
to or mentioned herein at the time or times and in the manner required.

8.4 - Legal  Status .  Borrower  will use its best  efforts to do or cause to be
done all things  necessary to preserve,  renew and keep in full force and effect
its  existences,  rights,  licenses,  permits and franchises and comply with all
laws and regulations applicable to it, and, further,  comply with all applicable
laws and regulations,  whether now in effect or hereafter enacted or promulgated
by any  governmental  authority  having  jurisdiction  over any of its assets or
properties, noncompliance with which would cause a Material Adverse Change.

8.5 -  Maintenance  and  Evidence of  Priority  of Bank Liens .  Borrower  shall
perform such acts and duly authorize, execute,  acknowledge,  deliver, file, and
record  such  additional  assignments,  security  agreements,  deeds  of  trust,
mortgages and other  agreements,  documents,  instruments  and  certificates  as
Lender may  reasonably  deem  necessary or  appropriate  in order to perfect and
maintain  the Bank Liens as a first lien and  preserve and protect the Rights of
Lender  in  respect  of all  present  and  future  Collateral,  and  cause to be
furnished to Lender such opinions of counsel as Lender may request regarding the
priority  of its title to, and the Bank Liens  upon,  its  assets,  all of which
opinions  shall be  prepared by such law firm or firms as may be  acceptable  to
Lender and which  shall be  prepared  in the same  format as those  prepared  in
accordance with Section 8.15 hereinbelow.

8.6 - Insurance . Borrower  presently  maintains  and will  continue to maintain
such policies of liability,  hazard, damage, business interruption and workmen's
compensation  insurance  as  are  customarily  carried  by  companies  similarly
situated.  If requested  by Lender,  any such  policies of insurance  shall show
Lender  therein as loss payee.  Upon  request by Lender,  Borrower  will furnish
Lender with  certificates  and  policies  necessary  to give  Lender  reasonable
assurance of the existence of such coverage.  Borrower agrees to notify promptly
Lender of any  termination  or other  material  change in  Borrower's  insurance
coverage,  and to provide Lender,  upon request,  with all information about the
renewal of each policy at least 15 days prior to the expiration thereof.

8.7 -  Reimbursement  of Fees and  Expenses . Borrower  agrees to pay all legal,
engineering,  and environmental fees and expenses  reasonably incurred by Lender
in connection with the investigation  and negotiation of the financing,  as well
as the preparation and execution of the Loan Papers; provided, however, that all
of such fees, costs, and expenses shall be credited against the Origination Fee.
If such fees and expenses exceed the amount of the Origination Fee, Lender shall
bear  all  such  fees  and  expenses,  not  to  include  those  costs  described
hereinbelow.  Borrower  agrees to pay all costs of filing and recording the Loan
Papers, all legal,  engineering,  and environmental fees and expenses reasonably
incurred by Lender or its  designated  representatives  in  connection  with any
renewal, extension, restatement, supplement or amendment of the Loan Papers, all
costs  associated  with  enforcing any of Lender's  Rights under the Loan Papers
(including,  without limitation, costs of repossessing,  storing,  transporting,
preserving and insuring any of the Collateral),  all court costs associated with
enforcing  or  defending  any  Rights  against   Borrower  or  any  third  party
challenging  said  Rights and any other cost or expense  reasonably  incurred by
Lender or its  designated  representatives  in  connection  herewith or with the
other Loan Papers,  together with interest at the Highest  Lawful Rate per annum
on each such amount commencing 10 days after the date notice of such expenditure
is given to Borrower by Lender until the date it is repaid to Lender.

8.8 - Indemnification . Borrower agrees to indemnify Lender from and against any
and all liabilities,  obligations,  claims, losses, damages, penalties, actions,
judgments,   suits,   remedial   actions,   costs,   expenses  or  disbursements
(collectively,  "Claims") of any kind or nature  whatsoever  that may be imposed
on, incurred by, or asserted against Lender by any third party growing out of or
resulting from (i) a breach of the Loan Papers and the  transactions  and events
at any time associated therewith (including, without limitation, the enforcement
of the Loan  Papers  and the  defense  of  Lender's  actions  and  inactions  in
connection  with the  Loan),  except  to the  limited  extent  such  Claims  are
proximately caused by Lender's gross negligence or willful misconduct;  (ii) the
presence of any Hazardous  Materials on or under properties  covered by the Deed
of  Trust;  or  (iii)  any  activity  carried  on or  undertaken  on or off  the
properties  covered  by the Deed of Trust,  whether  prior to or during the term
hereof and whether by  Borrower  or any third  person,  in  connection  with the
treatment,  storage,  recycling,  removal,  handling or  disposal  of  Hazardous
Materials at any time located on or under the properties  covered by the Deed of
Trust.

8.9 - Indemnification Procedure. In the event that Lender discovers or otherwise
becomes  aware of an  indemnification  claim  arising  under Section 8.8 of this
Agreement, Lender shall give written notice to Borrower,  specifying such claim,
and may  thereafter  exercise  any  remedies  available  to  Lender  under  this
Agreement;  provided,  however,  that the  failure  of Lender to give  notice as
provided herein shall not relieve Borrower of any obligations hereunder,  to the
extent Borrower is not materially  prejudiced thereby.  Further,  promptly after
receipt  by  Lender  of  written  notice of the  commencement  of any  action or
proceeding  with  respect  to  which a  claim  for  indemnification  may be made
pursuant to Section 8.8,  Lender shall,  if a claim in respect  thereof is to be
made against  Borrower,  give written notice to Borrower of the  commencement of
such  action;  provided  however,  that the  failure of Lender to give notice as
provided herein shall not relieve Borrower of any obligations hereunder,  to the
extent Borrower is not materially prejudiced thereby. In case any such action is
brought  against  Lender,  Borrower  shall be entitled to  participate in and to
assume the defense thereof,  jointly with any other indemnifying party similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to Lender, and after notice from Borrower to Lender of its election so to assume
the  defense  thereof,  Borrower  shall not be liable to Lender for any legal or
other  expenses  subsequently  incurred  by the  latter in  connection  with the
defense  thereof unless  Borrower has failed to assume the defense of such claim
and to employ counsel reasonably  satisfactory to Lender. If Borrower elects not
to assume the defenses of a claim, Borrower shall not be liable for the fees and
expenses of more than one  counsel in any single  jurisdiction  with  respect to
such claim or with respect to claims separate but similar or related in the same
jurisdiction arising out of the same general allegations. Notwithstanding any of
the foregoing to the contrary, Lender will be entitled to select its own counsel
and assume defense of any action brought  against it if Borrower fails to select
counsel  reasonably  satisfactory to Lender,  the expenses of such defense to be
paid by Borrower.  Borrower  shall not consent to entry of any judgment or enter
into any settlement with respect to a claim without the consent of Lender, which
consent  shall  not  be  unreasonably  withheld,  or  unless  such  judgment  or
settlement  includes as an unconditional term thereof a release of Lender by the
claimant or plaintiff  from all  liability  with  respect to such claim.  Lender
shall not consent to entry of any judgment or enter into any  settlement  of any
such  action,  the defense of which has been  assumed by  Borrower,  without the
consent of Borrower,  which consent shall not be unreasonably  withheld.  In the
event that Lender becomes entitled to compensation from Borrower pursuant to the
provisions  of Section 8.8, any such  compensation  shall bear  interest at that
Highest  Lawful Rate per annum from the date of  Lender's  payment of any claims
until paid by Borrower and shall be part of the  Obligation  secured by the Bank
Liens.

8.10 - Curing of  Defects .  Borrower  will  promptly  cure any  defects  in the
execution and delivery of any of the Loan Papers, and in any other instrument or
document referred to or mentioned herein.  Borrower will immediately execute and
deliver to Lender upon request, all such other and further instruments as may be
reasonably required or desired by Lender from time to time in compliance with or
accomplishment  of the  covenants  and  agreements  of Borrower made in the Loan
Papers.

8.11 - Inspection  and  Visitation . Borrower will grant Lender access to all of
its books and records, as well as to all of the Collateral, and allow inspection
and  copying  of same by Lender or its  designated  representatives  at any time
during  normal  business  hours or such  other  time as  Lender  may  reasonably
request;  provided,  however,  that nothing in this  Section 8.11 shall  require
Borrower to provide access to Lender to any books,  records,  or other materials
covered by a confidentiality  agreement that has been entered into as the result
of arms-length negotiations between Borrower and an unrelated third party.

8.12 -  Notices .  Borrower  will give  prompt  written  notice to Lender of any
proceedings  instituted against it by or in any federal or state court or before
any commission or other  regulatory  body,  federal,  state or local,  which, if
adversely determined, would cause a Material Adverse Change.

8.13 - Compliance . Borrower will observe and comply with:

(a) All laws, statutes, codes, acts, ordinances, rules, regulations,  directions
and requirements of all federal, state, county, municipal and other governments,
departments,  commissions, boards, courts, authorities,  officials and officers,
domestic and foreign,  including  but not limited to all  applicable  regulatory
requirements promulgated by any governmental agency including OSHA, the EPA, the
Pension  Benefit  Guaranty  Fund,  ERISA,  and any other  applicable  regulatory
agency,  where the failure to observe or comply  would cause a Material  Adverse
Change;

(b) all  orders,  judgments,  decrees,  injunctions,  certificates,  franchises,
permits,  licenses, and authorizations of all federal, state, county, municipal,
and other governments,  departments,  commissions,  boards, courts, authorities,
officials,  and officers,  domestic and foreign, which the failure to observe or
comply would cause a Material Adverse Change and against which it shall maintain
such reserves as are appropriate under GAAP; and

(c) GAAP in all of its accounting procedures.

8.14 -  Compliance  With  Environmental  Laws .  Borrower,  to the  best  of its
knowledge, is in substantial compliance with all state and federal environmental
laws and  regulations  and will remain in substantial  compliance  with same and
will not  place or permit to be placed  any  Hazardous  Materials  on any of its
properties in violation of applicable state and federal  environmental  laws. In
the event  Borrower  should  discover  any  Hazardous  Materials on any of their
properties  which could result in a breach of the foregoing  covenant,  Borrower
shall notify Lender within three (3) days after such  discovery.  Borrower shall
dispose of all material amounts of Hazardous  Materials  generated by it only at
facilities and/or with carriers that Borrower reasonably believes maintain valid
governmental permits under the Resource Conservation and Recovery Act, 42 U.S.C.
ss.6901.  In the event of any notice or filing of any procedure against Borrower
alleging a violation of any environmental law or regulation, Borrower shall give
notice to Lender within five (5) days after  receiving  notice of such notice or
filing.

8.15 -  Post-Closing  Title  Review.  Within sixty (60) days of the execution of
this Agreement,  Lender shall obtain title reports covering Mortgaged Properties
that represent  eighty percent (80%) or more of the net proven value of Lender's
most recent  engineering  evaluation.  Such title  reports  shall be prepared by
legal  counsel  of  Lender's  choice.  The cost of such title  reports  shall be
included in the Origination Fee. To the extent possible,  the title reports will
be based upon prior title opinions  obtained from  Borrower's  files and reports
prepared by landmen  selected by Lender  during the course of its due  diligence
review.  Within  thirty  (30) days of  Lender's  receipt of such title  reports,
Borrower  shall  cure any title  defects  reported  therein  for which  curative
activity is reasonably required by Lender, acting in its sole discretion.

                                   ARTICLE IX

(a) The  acceptance  by Lender at any time and from time to time of part payment
on the  Obligation  shall not  operate as a waiver of any Event of Default  then
existing.

(b) No waiver by Lender of any Event of Default shall operate as a waiver of any
other then existing or subsequent Event of Default.

(c) No delay or omission  by Lender in  exercising  any Right shall  impair such

obligation, if any, to make further Advances.

11.4 - Strict  Compliance . If any action or failure to act by Borrower violates
any covenant of Borrower  contained herein or in any other Loan Paper, then such

covenant) other than the covenant violated.

11.5 -  Cumulative  Rights . The Rights of Lender  under the Loan  Papers are in
addition to all other Rights  provided by law,  whether or not the Obligation is

delivered,  and  is  intended  to be  performed,  in the  State  of  Texas.  The

the Loan Papers or any judgment entered by any court in respect thereof,  may be

that they may now or hereafter  have to the laying of venue of any suit,  action
or proceeding arising out of or relating to any of the other Loan Papers brought
in any said courts and hereby further  irrevocably waive any claim that any such
suit,  action or  proceeding  brought in any such  court has been  brought in an
inconvenient forum and any right granted by statute,  rule or court or otherwise
to have such suit, action or proceeding tried by a jury.

conduct or course of conduct by any or all of the parties hereto, whether before
or after signing this Agreement or any other Loan Paper,  no Loan Paper shall be
construed  as creating  any right,  claim or cause of action  against  Lender in
favor of any  third  party,  including,  without  limitation,  any  materialman,
supplier, contractor, subcontractor,  purchaser, lessor or lessee having a claim
against Borrower.

(b) All  conditions to the  obligation of Lender to make Advances  hereunder are
imposed solely and  exclusively  for the benefit of Lender,  and no other person
shall have  standing to require  satisfaction  of such  conditions in accordance
with their  terms or be  entitled  to assume  that Lender will make or refuse to
make Advances in the absence of strict compliance  therewith,  and any or all of
such  conditions  may be freely waived in whole or in part by Lender at any time
if Lender, in its sole and absolute discretion, deems it advisable to do so.

11.11 - Delegation  by Lender . Lender may perform any of its duties or exercise
any of its Rights by or through its officers, directors,  employees,  attorneys,
agents or other representatives.

11.12 - Setoff . Borrower  hereby grants to Lender (and to each  participant  to
whom Lender has conveyed or may hereafter  convey a  participation  in the Note)
the right of setoff (which right shall not be exercised  prior to the occurrence
of an Event of Default)  to secure  payment of the  obligation  upon any and all
moneys, securities or other property of Borrower and the proceeds therefrom, now
or  hereafter  held  or  received  by or in  transit  to,  Lender  or  any  such
participant or any agent of Lender or such participant,  from or for the account
of Borrower, whether for safekeeping, custody, pledge, transmission,  collection
or  otherwise,  and also upon any and all  deposits  (general or  specific)  and
credits of  Borrower  and any and all claims of Borrower  against  Lender or any
such participant at any time existing.

11.13 -  Additional  Documents  . It is  contemplated  that there may be certain
supplementary and/or corrective  mortgages,  deeds of trust, security agreements
and similar  items  prepared  by Lender to be  executed  by Borrower  subsequent
hereto,  as well as certain other  corrective and additional  documentation  not
executed  concurrently  with this  Agreement  because of the  unavailability  of
information  such as property  and  collateral  descriptions  at the time of the
execution  hereof.  Borrower  agrees to  cooperate  with Lender and provide such
information  in connection  therewith as Lender may reasonably  request,  and to
execute  and  deliver  such  other and  further  documentation  as Lender  shall
reasonably  request so as to provide Lender with a Bank Lien on the  Collateral.
Further,  upon Lender's  reasonable  request,  Borrower shall provide such title
opinions and division orders as are necessary to establish  Borrower's  title to
the Mineral Interests.

11.14  -  Counterparts  .  This  Agreement  may be  executed  in any  number  of
counterparts,  each of which shall be deemed to be an original, but all of which
taken together shall constitute one and the same instrument.

11.15 - Amendments  . Neither this  Agreement  nor any  provision  hereof may be
changed,  waived,  discharged or terminated  orally but only by an instrument in
writing signed by Borrower and Lender.

11.16 - Headings . All headings  used herein are for  convenience  and reference
purposes only and shall not affect the substance of this Agreement.

11.17 - Conflicts . In the event that there exists any conflict or inconsistency
between the terms hereof and the terms of any other Loan Paper, the terms hereof
shall  govern  and  control,  provided  that the fact  that any  representation,
warranty or covenant  contained in any other Loan Paper is not contained  herein
shall not be, or be deemed to be, a conflict or inconsistency.

11.18 - Entirety . This  Agreement  and the other Loan Papers  embody the entire
agreement among the parties and supersede and supplant all prior  agreements and
understandings with respect to the matters contained herein.

11.19 - Notice of Final Agreement . THIS AGREEMENT, THE PROMISSORY NOTE, AND ANY
CONTRACTS  OR  INSTRUMENTS  RELATING  THERETO,  REPRESENT  THE ENTIRE  AGREEMENT
BETWEEN THE PARTIES, AND IT IS EXPRESSLY UNDERSTOOD THAT ALL PREVIOUSLY EXECUTED
LOAN PAPERS AND PRIOR  CONVERSATIONS OR MEMORANDA  BETWEEN THE PARTIES REGARDING
