      FOR VALUE RECEIVED,  Touchstone  Louisiana,  Inc., a Delaware  corporation
with a principal  place of business at 111  Presidential  Boulevard,  Suite 165,
Bala  Cynwyd,  PA 19004 (the  "Borrower"),  hereby  promises to pay to Endeavour
International  Corporation,  a  Nevada  corporation  with a  principal  place of
business at 1001 Fannin Street, Suite 1700, Houston, Texas 77010 (the "Lender"),
the principal sum of Two Million Dollars ($2,000,000), together with interest on
the unpaid principal balance from time to time outstanding, from the date hereof
until  maturity  at a fixed  rate per  annum  equal to three  percent  (3%) (the
"Stated  Rate").  Interest  on this Note shall be  calculated  at an annual rate
based on the actual number of days elapsed in an actual  calendar year (365 days
or 366 days in a leap year, as may be applicable).

      Principal  and interest  under this Note shall be due and payable upon the
operator's completion of the first oil and/or gas well to be completed after the
date hereof  (whether a new well, a sidetrack,  re-entry or otherwise) on any of
the oil, gas and/or mineral leases  described on Schedule 1 attached hereto (the
"Leases")  (such well, the "First Well") (the completion of such First Well, the
"Triggering Event") with payments due as follows:

            (i) Regular Monthly Installments.  On or before each Monthly Payment
      Date,  beginning with the Initial Monthly Payment Date, Borrower shall pay
      Lender an amount equal to the Percentage Interest of the Monthly Cash Flow
      for the immediately  preceding  calendar  month,  until the Borrower shall
      have paid this  Note and all  accrued  interest  and  other  payments  due
      hereunder in full. Each such monthly installment shall be applied first to
      accrued and unpaid  interest,  then to other payments due  hereunder,  and
      then to  principal.  As used herein,  the  following  terms shall have the
      following meanings:

            "Monthly Cash Flow" shall mean, on a cash basis,  for the applicable
            calendar  month  (beginning  with the  calendar  month in which  the
            Initial  Production  Date shall occur),  any positive  dollar amount
            that results  after  subtracting  from the gross  proceeds  received
            during such calendar  month by Louisiana  Shelf  Partners,  L.P. and
            attributable  to or in lieu of production from all of the oil and/or
            gas wells completed on the Leases in which Louisiana Shelf Partners,
            L.P. has any interest including,  without limitation, the First Well
            (collectively,    the   "LSP   Wells"),   the   following   (without
            duplication),  to  the  extent  actually  paid  by  Louisiana  Shelf
            Partners,  L.P.  during such month:  (a) any royalty and  overriding
            royalty  payments  in  respect  of royalty  and  overriding  royalty
            interest  presently  burdening  the LSP  Wells,  and  (b) any  lease
            operating  expenses for the LSP Wells (but in no event including any
            expenses for drilling,  completing or reworking the LSP Wells or for
            pipeline or facilities  construction,  whether  incurred prior to or
            after  first  production  of any  such  Well).  Notwithstanding  the
            foregoing,  if,  despite  Borrower's  commercially  reasonable  best
            efforts set forth in clause (v) below, Louisiana Shelf Partners, L.P
            sells,  transfers,  assigns or farms out any of its right, title and
            interest in the Leases, Monthly Cash Flow shall also include the net
            proceeds  (i.e.,   gross  proceeds  less  reasonable   out-of-pocket

<PAGE>

            transaction   expenses)  received  during  such  calendar  month  by
            Louisiana  Shelf  Partners,  L.P. from such transfer,  assignment or
            farm-out.

            "Initial  Production Date" shall mean the date that first production
            from the First Well is saved and sold.

            "Initial  Monthly  Payment Date" shall mean the third (3rd) business
            day of the calendar month  following the calendar month in which the
            Initial Production Date occurs.

            "Monthly  Payment Date" shall mean each third (3rd)  business day of
            each calendar month beginning with and including the Initial Monthly
            Payment Date.

            "Percentage  Interest"  shall  mean  24.9975%,   being  the  present
            ownership percentage interest of the limited partnership interest of
            Borrower in Louisiana  Shelf  Partners,  L.P., or in the event of an
            increase in the percentage interest of limited partnership  interest
            of  Borrower  in  Louisiana  Shelf  Partners,   L.P.,  such  greater
            percentage interest.

            (ii) First  Conditional  Accelerated  Payment.  In  addition  to any
      monthly  payments  provided  for in  paragraph  (i) above,  if the Initial
      Production  Rate for any of the LSP Wells  meets or  exceeds  the  Initial
      Production  Threshold,  then Borrower  shall make a  supplemental  payment
      equal to the lesser of: (a) the  remaining  unpaid  principal and interest
      due  hereunder or (b) the sum of $800,000 (to be applied to the  reduction
      of  principal)  plus an amount  equal to all accrued  but unpaid  interest
      hereunder.  Such conditional  payment will be due and payable on or before
      the date which is 30 days following the  Completion  Date of such Well. As
      used herein, the following terms shall have the following meanings:

            "Initial Production Rate" shall mean the average gross daily rate of
            natural gas production  from the applicable  Well expressed in cubic
            feet during the first five (5) 24-hour days of production  beginning
            with  the  Initial  Production  Date.  For  purposes  of  all of the
            definitions  in this Note,  any oil or condensate  produced from the
            Well will be deemed  natural gas production and converted to natural
            gas at the  ratio of 1 barrel  of oil or  condensate  to 6  thousand
            cubic feet of gas.

            "Initial  Production  Threshold"  means an Initial  Production  Rate
            averaging  five (5)  million  cubic  feet or more per day of natural
            gas.

            "Completion  Date" shall mean,  for the First Well,  the date of the
            Triggering  Event, and for any other LSP Well, the date such well is
            completed.

            "completed" or  "completion"  shall mean, for any well, the stage at
            which such well has been  prepared for and is capable of its initial
            production  of oil and/or gas,  and the date of  completion  for any
            well shall be the earlier of: (i) the date of first  production from
            such well, or (ii) the date the  completion rig finishes the work of
            completing such well and moves off the well bore.

                                       2

            (iii) Second  Conditional  Accelerated  Payment.  In addition to any
      monthly  payments  provided for in paragraph (i) above and any conditional
      accelerated  payment  provided for in paragraph (ii) above, if the Initial
      Production  Rate for any LSP Well meets or exceeds the Initial  Production
      Threshold and  thereafter the Six-Month  Production  Rate for any LSP Well
      equals  or  exceeds  three (3)  million  cubic  feet of gas per day,  then
      Borrower  shall  make a  supplemental  payment  in an amount  equal to the
      lesser of: (a) the remaining unpaid principal and interest  hereunder,  or
      (b) the sum of $1,200,000  (to be applied to reduction of principal)  plus
      an  amount  equal to all  accrued  but  unpaid  interest  hereunder.  Such
      conditional payment will be due and payable on or before the date which is
      30 days  following the end of the fifth (5th) calendar month as prescribed
      in the definition of Six-Month  Production  Rate below. As used herein the
      following term shall have the following meaning:

            "Six-Month  Production  Rate" means the average  gross daily rate of
      production  from the  applicable  LSP Well during the fifth (5th) calendar
      month  following the calendar month in which the date of first  production
      for such well occurs.

            (iv) If no LSP Well achieves the Initial Production  Threshold,  the
      sole source of payment of principal  and interest due  hereunder  shall be
      the amounts  payable out of  production  as  prescribed  in paragraph  (i)
      above.

            (v) Borrower agrees to use its commercially  reasonable best efforts
      to cause Louisiana Shelf Partners,  L.P. not to sell, transfer,  assign or
      farm out any of its right, title and interest in the Leases.

            All past due  principal  of, and interest on, this Note shall accrue
      interest  from the date due  until the date it is paid at the lower of (i)
      4% plus the Stated  Rate per annum and (ii) the  maximum  rate  allowed by
      law.  Except as to the  conditional  supplemental  payments  prescribed in
      paragraphs (ii) and (iii) above,  this Note shall  represent  non-recourse
      debt of the Borrower.

      The Borrower shall have the right,  from time to time,  without premium or
penalty, to prepay the indebtedness evidenced by this Note, in full or in part.

      All payments (including prepayments) to be made by the Borrower hereunder,
whether on account of principal,  interest or  otherwise,  shall be made without
set off or counterclaim  and shall be made on or prior to the due date set forth
above to the Lender at the address set forth  above,  or such other place as the
Lender may from time to time  designate in writing.  If any payment or action to
be made or taken  hereunder shall be stated to be or become due on a day that is
not a business  day,  such  payment or action shall be made or taken on the next
following business day and such extension of time shall be included in computing
interest or fees, if any, in connection with such payment or action.

      "Event of Default,"  wherever used herein,  means any one of the following
events  (whatever  the reason for such Event of Default  and whether it shall be
voluntary or  involuntary  or be effected by operation of law or pursuant to any
judgment,  decree or order of any court or any order,  rule or regulation of any
governmental authority):

                                       3

            (a) default in the payment of the  principal  sum of this Note,  and
      any interest accrued thereon, when such principal and interest becomes due
      and payable (whether by acceleration or otherwise), or

            (b) the entry by a court having  jurisdiction in the premises of (A)
      a decree or order for relief in respect of the Borrower in an  involuntary
      case or  proceeding  under any  applicable  Federal  or State  bankruptcy,
      insolvency,  reorganization  or other similar law or (B) a decree or order
      adjudging the Borrower a bankrupt or  insolvent,  or approving as properly
      filed  a  petition  seeking  reorganization,  arrangement,  adjustment  or
      composition of or in respect of the Borrower under any applicable  Federal
      or State law, or appointing a custodian, receiver,  liquidator,  assignee,
      trustee,  sequestrator or other similar official of the Borrower or of any
      substantial  part  of  its  property,   or  ordering  the  winding  up  or
      liquidation  of its  affairs,  and the  continuance  of any such decree or
      order for relief or any such other decree or order  unstayed and in effect
      for a period of 90 consecutive days; or

            (c)  the  commencement  by  the  Borrower  of a  voluntary  case  or
      proceeding under any applicable  Federal or State bankruptcy,  insolvency,
      reorganization  or other similar law or of any other case or proceeding to
      be adjudicated a bankrupt or insolvent,  or the consent by it to the entry
      of a  decree  or  order  for  relief  in  respect  of the  Borrower  in an
      involuntary  case or  proceeding  under any  applicable  Federal  or State
      bankruptcy,  insolvency,  reorganization  or other  similar  law or to the
      commencement  of any bankruptcy or insolvency  case or proceeding  against
      it,  or the  filing by it of a  petition  or  answer  or  consent  seeking
      reorganization or relief under any applicable Federal or State law, or the
      consent by it to the filing of such petition or to the  appointment  of or
      taking possession by a custodian, receiver, liquidator, assignee, trustee,
      sequestrator  or similar  official of the  Borrower or of any  substantial
      part of its property, or the making by it of an assignment for the benefit
      of  creditors,  or the  admission by it in writing of its inability to pay
      its debts generally as they become due, or the taking of corporate  action
      by the Borrower in furtherance of any such action.

      Upon the  occurrence  of an Event of  Default,  the  entire  amount of the
indebtedness  evidenced by this Note shall be immediately due and payable.  Upon
the  acceleration of the  obligations  evidenced by this Note and failure by the
Borrower  to pay  amounts  then due  hereunder,  Lender may  proceed to protect,
exercise  and  enforce all of its rights and  remedies  under this Note and that
certain Interest Purchase Agreement, dated as of even date herewith, between the
Borrower and the Lender and applicable  law. The remedies  provided in this Note
are  cumulative  and  concurrent,  may  be  pursued  in any  order,  separately,
successively  or together,  may be  exercised as often as occasion  therefor may
arise, and shall be in addition to, and not in substitution  for, the rights and
remedies  that  would  otherwise  be vested in the Lender  for the  recovery  of
damages,  or otherwise,  in the event of a breach of any of the  undertakings of
the  Borrower  hereunder.  This Note may not be  modified,  altered or  amended,
except by an agreement in writing signed by the Borrower and the Lender.

      It is the  intention  of the parties  hereto to conform  strictly to usury
laws  applicable to the holder of this Note.  Accordingly,  if the  transactions
contemplated  hereby would be usurious under  applicable law (including the laws
of the United  States of America and the State of Texas),  then,  in that event,
notwithstanding  anything to the contrary in this Note, it is agreed as follows:
(i) the aggregate of all  consideration  which  constitutes  interest  under law
applicable to the holder of this Note that is contracted for,  taken,  reserved,
charged or  received  under this Note shall  under no  circumstances  exceed the

                                       4
<PAGE>

maximum  amount  allowed  by such  applicable  law;  (ii) in the event  that the
maturity of this Note is  accelerated  by reason of an election of the holder of
this Note resulting from any Event of Default,  or in the event of any permitted
prepayment,   then  such  consideration  that  constitutes  interest  under  law
applicable  to the holder of this Note may never  include  more than the maximum
amount  allowed by such  applicable  law,  and (iii)  excess  interest,  if any,
provided for in this Note or otherwise shall be canceled  automatically  and, if
theretofore  paid, shall be credited by the holder of this Note on the principal
amount of this Note (or,  to the extent that the  principal  amount of this Note
shall have been or would thereby be paid in full, refunded by the holder of this
Note to the  Borrower).  The right to accelerate  the maturity of this Note does
not include the right to accelerate any interest that has not otherwise  accrued
on the date of such acceleration, and the holder of this Note does not intend to
collect any  unearned  interest in the event of  acceleration.  All sums paid or
agreed  to be paid to the  holder  of this  Note  for the  use,  forbearance  or
detention  of sums  included  in this Note  shall,  to the extent  permitted  by
applicable law, be amortized, prorated, allocated and spread throughout the full
term of this Note until  payment in full so that the rate or amount of  interest
on account of the  indebtedness  under this Note does not exceed the  applicable
usury ceiling,  if any. As used in this  paragraph,  the term  "applicable  law"
shall mean the law of the State of Texas.

      All  reasonable   attorney's  fees  and  expenses  and  other   reasonable
out-of-pocket  costs incurred by the Lender in connection with the collection of
this Note  subsequent  to an Event of Default (as defined  herein)  shall become
amounts  due and owing  under the  terms of this Note in  addition  to all other
amounts owing pursuant to the other provisions of this Note.

      Borrower hereby waives demand, presentment for payment, protest, notice of
protest, notice of intention to accelerate the indebtedness hereunder, notice of
the acceleration of the indebtedness  hereunder and filing of suit and diligence
in collecting this Note or enforcing of any of the rights of Lender.

      This Note shall bind the Borrower and its successors and assigns,  and the
benefits  hereof shall inure to the benefit of the Lender and its successors and
assigns,  except that Borrower may not sell, assign or transfer this Note or any
portion hereof without  obtaining the prior written  consent of the Lender.  All
references herein to the "Borrower" and the "Lender" shall be deemed to apply to
the Borrower and the Lender,  respectively,  and their respective successors and
assigns.

      This Note and any other documents delivered in connection herewith and the
rights and  obligations of the parties hereto and thereto shall for all purposes
be governed by and construed  and enforced in accordance  with the internal laws
of the State of Texas without giving effect to its conflicts of law principles.

      IN WITNESS WHEREOF, the undersigned, intending to be legally bound hereby,
has executed  this Note as of the date first  written  above with the  intention
that this Note shall constitute a sealed instrument.
