PROMISE TO PAY.
- ---------------

         Goodrich  Petroleum  Company,  L.L.C.  ("Borrower")  promises to pay to
                      ("Lender"), or order, in lawful money of the United States
- ----------------------
of  America,  the  principal  amount of ($ ), or so much as may be  outstanding,
together with interest on the unpaid outstanding principal balance from the Date
of  Note,  as  indicated  above,  until  such  balance  is  paid in  full.  This
Convertible  Promissory  Note  executed by Borrower in favor of Lender  shall be
referred to as a "Note".

1.       PAYMENT OF PRINCIPAL AND ACCRUED INTEREST.
         ------------------------------------------

     Beginning  as of the date of this Note  first  written  above (the "Date of
Note") and continuing until the outstanding  principal  balance is paid in full,
interest will accrue at an annual rate of Eight Percent (8.0%). Interest will be
computed on a 365/360 day basis compounding monthly; that is in each month 1/360
of the Eight Percent (8.0%) annual  interest rate, will be multiplied by (a) the
sum of (i) the  outstanding  principal  balance  and (ii)  accumulated  interest
outstanding  as of the end of the prior month and (b) the actual  number of days
that the principal was outstanding in such month.

     1.1 Interest Accrual Period. Beginning as of the Date of Note first written
above and continuing  through October 1, 2002 (the "Interest  Accrual  Period"),
interest shall accrue at an annual rate of Eight Percent (8.0%),  compounding on
the last date of each calendar month as described above;  provided,  however, if
the Collateral  Agent commences any action (judicial or  extrajudicial)  against
any  collateral  held by it  pursuant  to the  terms  of the  Collateral  Agency
Agreement, then such interest as may thereafter accrue shall be payable monthly,
in arrears,  on or before the first day of each month thereafter.  If on October
1,  2002,  the  common  stock of  Goodrich  Petroleum  Corporation,  a  Delaware
Corporation  ("Goodrich-Delaware")  has a  closing  price of at least  $4.00 per
share,  as adjusted  pursuant to Section 3.2 hereof (the "First  Benchmark Stock
Price"),  then,  at  Borrower's  option the  Interest  Accrual  Period  shall be
extended  to  October  1, 2003  (the  "First  Extension  Option").  If  Borrower
exercised  the First  Extension  Option,  and if on October 1, 2003,  the common
stock of  Goodrich-Delaware  has a closing price of at least $5.00 per share, as
adjusted  pursuant to Section 3.2 hereof (the "Second  Benchmark  Stock Price"),
then, at Borrower's  option,  the Interest  Accrual  Period shall be extended to
October 1, 2004 (the "Second Extension Option").

     1.2  Principal  Repayment  Period.  Beginning as of the end of the Interest
Accrual Period  (initially  October 1, 2002, but as may be adjusted  pursuant to
Section 1.1 above),  the sum of all principal and accrued  interest  through the

                                       1


last day of the Interest  Accrual  Period shall be repaid in  twenty-four  equal
monthly  installments  beginning on the last day of the Interest  Accrual Period
and  continuing  on the first day of the  subsequent  twenty-three  months.  The
period of time  beginning  on the last day of the  Interest  Accrual  Period and
ending on the first day of the month that is twenty- three months after the last
day of the  Interest  Accrual  Period  shall be  referred  to as the  "Principal
Repayment Period".  For example,  if the last day of the Interest Accrual Period
is October 1, 2002, the Principal Repayment Period shall be from October 1, 2002
through September 1, 2004.

     1.3  Payment  of  Interest.  During the  Principal  Repayment  Period,  all
interest that accrues  beginning on the last day of the Interest  Accrual Period
(initially  October  1,  2002,  but as may be  adjusted  by the First  Extension
Option, or the Second Extension Option),  shall be paid monthly on the first day
of each of the following months during the Principal Repayment Period.

2.       CONVERSION OF PRINCIPAL AND ACCRUED INTEREST.
         ---------------------------------------------

     Beginning as of the Date of this Note first  written  above and  continuing
until all accrued  interest  and the  outstanding  principal  balance is paid in
full,  Lender may, at its option pursuant to the terms hereof,  by delivering to
Borrower a  Conversion  Notice,  as defined  in  Section  2.2,  elect to require
Borrower  to  convert  all or  part  of the  accrued  interest  and  outstanding
principal  that is owing  into  shares of  Goodrich-Delaware's  common  stock as
follows:

     2.1 Conversion.  Some or all of the accrued  interest and principal  amount
outstanding shall be convertible into a number of shares of  Goodrich-Delaware's
common  stock,  which number of shares shall be equal to the quotient of (a) the
total accrued interest and outstanding  principal subject to conversion  divided
by (b) the  Conversion  Price,  as  defined  in  Section  3.1  (the  "Conversion
Option").

     2.2 Conversion  Notice.  "Conversion  Notice" shall mean the written notice
that Lender may, at its option, give to Borrower, notifying Borrower of Lender's
decision to exercise a  Conversion  Option to convert some or all of the accrued
interest and  outstanding  principal into shares of  Goodrich-Delaware's  common
stock.    Borrower   will   deliver   to   Lender   the   required   shares   of
Goodrich-Delaware's  common stock within five (5) business days of receiving the
Conversion Notice.

     2.3 Minimum  Conversion  Amount.  Each Conversion Notice given by Lender to
Borrower  shall  be for no less  that 10% of the  total  amount  of  outstanding
principal and accrued  interest owing under this Note from Borrower to Lender at
the time that the Conversion Notice is given.

3.       CONVERSION PRICE.
         -----------------

     3.1  Conversion  Price.  The  "Conversion  Price" as used herein shall mean
$4.00, as adjusted pursuant to Section 3.2 hereof.


     3.2 Adjustment to Conversion Price.

          3.2.1  Definitions.  As used in this Section 3.2 the  following  terms
shall have the following respective meanings:

                                       2


               (a) "Common Stock" shall mean shares of the presently  authorized
common stock of Goodrich-Delaware and any stock into which such common stock may
hereafter be exchanged.

               (b)  "Options"  shall mean the  rights,  options or  warrants  to
subscribe  for,  purchase  or  otherwise  acquire  shares  of  Common  Stock  or
Convertible Securities.

               (c) "Convertible Amounts" shall mean the aggregate dollar amounts
that are subject to  conversion  at any given time  pursuant  to the  Conversion
Option.

               (d)   "Convertible   Securities"   shall  mean  any  evidence  of
indebtedness,  shares  of stock  or  other  securities  directly  or  indirectly
convertible into or exchangeable for Common Stock.

          3.2.2  Adjustments to Conversion  Price. The Conversion Price shall be
subject to adjustment  from time to time upon the occurrence of certain  events,
as follows:

               (a) Reclassification, Reorganization, Consolidation or Merger. In
the case of any  reclassification  of the Common Stock,  or any  reorganization,
consolidation or merger of  Goodrich-Delaware  with or into another  corporation
(other than a merger or reorganization  with respect to which  Goodrich-Delaware
is the continuing  corporation and which does not result in any reclassification
of the Common  Stock),  each share of Common  Stock  theretofore  issuable  upon
exercise of any Conversion  Option,  shall be properly adjusted as to the number
and kind of securities  receivable  upon the exercise of any Conversion  Option,
such that Lender shall receive the number and kind of securities  which a holder
of Common Stock would have been  entitled to receive  after the happening of any
of the events  described in this  subsection (a) had the conversion  pursuant to
any Conversion Option been made immediately prior to the happening of such event
or the record date for such event,  whichever is earlier. The provisions of this
subsection   (a)  shall   similarly   apply  to  successive   reclassifications,
reorganizations, consolidations or mergers.

               (b)   Split,   Subdivision   or   Combination   of   Shares.   If
Goodrich-Delaware  at any time  prior to  Lender's  exercise  of any  Conversion
Option shall split,  subdivide or combine the Common Stock of Goodrich-Delaware,
the Conversion Price shall be  proportionately  decreased in the case of a split
or subdivision or  proportionately  increased in the case of a combination.  Any
adjustment  under this  subsection  (b) shall become  effective  when the split,
subdivision or combination becomes effective.

               (c) Stock Dividends.  If  Goodrich-Delaware  at any time prior to
Lender's  exercise of any Conversion Option shall pay a dividend with respect to
Common Stock of Goodrich-Delaware payable in shares of Common Stock, Options, or
Convertible  Securities,  the Conversion Price shall be adjusted, from and after
the date of determination of the shareholders  entitled to receive such dividend
or  distributions,  to that price determined by multiplying the Conversion Price
in effect  immediately prior to such date of determination by a fraction (i) the
numerator  of which  shall  be the  total  number  of  shares  of  Common  Stock
outstanding  immediately  prior to such dividend or  distribution,  and (ii) the
denominator  of which  shall be the total  number  of  shares  of  Common  Stock
outstanding  immediately  after such dividend or distribution  (including Common
Stock  issuable  upon  exercise,   conversion  or  exchange  of  any  Option  or
Convertible Securities issued as such dividend or distribution).  If the Options
or Convertible Securities issued as such dividend or distribution by their terms
provide,  with  the  passage  of time or  otherwise,  for  any  decrease  in the
consideration  payable to  Goodrich-Delaware,  or any  increase by the number of

                                       3


shares issuable upon exercise, conversion or exchange thereof (by change of rate
or otherwise),  the Conversion  Price shall,  upon any such decrease or increase
becoming effective,  be reduced to reflect such decrease or increased to reflect
such increase as if such decrease or increase became effective immediately prior
to the  issuance of the Options or  Convertible  Securities  as the  dividend or
distribution. Any adjustment under this subsection (c) shall become effective on
the record date.

               (d) Other Securities.  In the event Goodrich-Delaware at any time
prior to Lender's  exercise of any  Conversion  Option makes,  or fixes a record
date for the  determination  of holders of Common Stock  entitled to receive,  a
dividend or other distribution payable in securities of Goodrich-Delaware  other
than shares of Common Stock,  then, and in each such event,  provision  shall be
made so that the Lender shall receive,  upon exercise of any Conversion  Option,
in addition to the number of shares of Common Stock  receivable  thereupon,  the
amount of  securities  of the Borrower  which the Lender would have received had
the Convertible  Amounts been  exchangeable for such Common Stock on the date of
such event and had the  Lender  thereafter,  during the period  from the date of
such event to and  including  the date of  exercise,  retained  such  securities
receivable  by Lender as  aforesaid  during  such  period,  subject to all other
adjustments called for during such period under this Section 3.2 with respect to
the rights of the Lender.

          3.2.3 Other  Adjustments.  The First Benchmark Stock Price, the Second
Benchmark Stock Price, and the Clawback Price shall all be subject to adjustment
in the same  manner  and to the same  extent  as those  adjustments  made to the
Conversion Price pursuant to Section 3.2.2 above.

          3.2.4  Fractional  Shares.  Pursuant  to the  Conversion  Options,  no
fractions  of  shares of  Common  Stock  shall be  issued,  but in lieu  thereof
Borrower  shall pay a cash  adjustment  to Lender in respect of such  fractional
interest in an amount equal to such fractional  interest  multiplied by the then
applicable Conversion Price; provided,  however, that no payment will be made in
respect of such cash  adjustment  if the amount  payable is less than Twenty and
No/100 Dollars ($20.00).

          3.2.5 Reserving  Shares.  Borrower shall at all times reserve and keep
available  out of its  authorized  and  unissued  Common  Stock,  solely for the
purpose of effecting the Conversion Options of Lender,  such number of shares of
Common  Stock as shall from time to time be adjusted  pursuant to this Section 3
hereof.

          3.2.6  Registration of Shares.  Goodrich-Delaware  shall file with the
SEC within  sixty (60) days  following  the Date of Note  hereof a  registration
statement  on Form S-1 under the  Securities  Act of 1933,  as amended,  or such
other form that the Company is eligible to use or that the SEC deems appropriate
(the "Registration  Statement") for the registration of the resale by the Lender
of the common stock of  Goodrich-Delaware  issuable upon conversion of this Note
("Registrable  Securities").  The Company shall use its best efforts to have the
Registration  Statement  declared  effective  by the SEC by no later than ninety
(90) days  after the Date of Note  hereof  and to ensure  that the  Registration
Statement,  and the underlying prospectus,  remains in effect for so long as any
Registrable Shares are outstanding.

               (a)  Notwithstanding the foregoing,  Goodrich-Delaware  may defer
the filing of the Registration  Statement until a date not later than sixty (60)
days after the time set forth above if Goodrich-Delaware or its subsidiaries are
engaged in confidential  negotiations or other confidential business activities,
disclosure of which would be required in such Registration  Statement (but would
not be required if such Registration Statement were not filed).

               (b)   Notwithstanding   the   foregoing,   if   Goodrich-Delaware
determines  in its good  faith  judgment  that the filing of any  supplement  or
amendment  to the  Registration  Statement  in order  to keep  the  Registration

                                       4


Statement  effective would require the disclosure of material  information  that
Goodrich-Delaware   has  a  bona  fide  business   purpose  for   preserving  as
confidential,    then   upon   written   notice   of   such   determination   by
Goodrich-Delaware   to  the  Lender,  the  obligation  of  Goodrich-Delaware  to
supplement  or  amend  the  Registration   Statement  will  be  suspended  until
Goodrich-Delaware notifies the Lender in writing that the reasons for suspension
of such obligations no longer exist and Goodrich-Delaware  amends or supplements
the Registration Statement as may be required. The maximum number of consecutive
days during which  Goodrich-Delaware may delay the filing of any such supplement
or amendment shall not exceed sixty (60) days.

          3.2.7 Notice of Adjustments. Whenever the Conversion Price is adjusted
pursuant to Section 3 hereof,  Borrower  shall promptly issue a notice signed by
its chief financial  officer or chief executive  officer stating,  in reasonable
detail,  the new  Conversion  Price  as a  result  of each  adjustment,  a brief
statement of the facts requiring such  adjustments and the computation  thereof,
and the date such  adjustments  became  effective,  and Borrower  shall mail (by
first class mail,  postage prepaid) to Lender at Lender's address a copy of such
notice.

4.       PREPAYMENT.
         -----------

     Some or all of the  outstanding  principal and accrued  interest under this
Note may be prepaid at any time without penalty, pursuant to the terms described
herein (the  "Prepayment  Option").  Borrower may only  exercise the  Prepayment
Option, if after giving Lender twenty (20) day's prior written notice Lender has
not elected to exercise its Conversion  Option for such amount as Borrower wants
to prepay.

5.       BORROWER'S OPTION.
         ------------------

     If  Borrower  notifies  Lender that it wishes to  exercise  its  Prepayment
Option  for  amounts  that are not due for at least one year,  and  Lender  then
elects to use its Conversion Option for such amounts, then Goodrich-Delaware may
elect to  repurchase  one half of the Common  Stock that  Lender  received  as a
result of exercising  such  Conversion  Option at a price of $6.00 per share, as
adjusted pursuant to Section 3.2 (the "Clawback  Price").  This option shall not
be assignable by Goodrich-Delaware to any other party.

6.       METHOD OF PAYMENT.
         ------------------

     Borrower will pay Lender  principal and interest that is not converted into
shares of  Goodrich-Delaware's  common stock pursuant to the Conversion  Option,
and loan fees by check made payable to the Lender drawn on a United  States bank
and for United  States  dollars,  or by wire transfer to an account of Lender at
Lender's  address  shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to any remaining  amount of any unpaid  collection  costs and late
charges, then to accrued unpaid interest and then to any unpaid principal.

7.       FIXED INTEREST RATE.
         --------------------

     The interest  rate on this Note is Eight Percent  (8.0%) per annum,  or, if
lower, the maximum rate of interest allowed by applicable law.

9.       DEFAULT.
         --------

     Borrower  will be in  default  if any  Event of  Default  occurs  under the
Goodrich Credit Agreement.

10.      LENDER'S RIGHTS.
         ----------------

     Upon the  occurrence  and during the  continuance  of an Event of  Default,
Lender may  declare  the entire  unpaid  principal  balance on this Note and all
accrued unpaid interest  immediately due and payable,  without notice,  and then
Borrower  will pay that  amount.  Upon  Borrower's  failure  to pay all  amounts
declared  due  pursuant  to this  section,  including  failure to pay upon final
maturity,  Lender at its option, may also, if permitted under applicable law, do
one or both of the following:  (a) increase the interest rate on this Note up to
eighteen  percent  (18%) per annum,  or, if lower,  up to the  maximum  interest
amount  allowable by applicable law, and (b) add any unpaid accrued  interest to
principal  and such sum will  bear  interest  therefrom  until  paid at the rate
provided  in this  Note.  Borrower  agrees to pay all  reasonable  out of pocket
expenses of Lender in connection  with the  collection  and  enforcement of this
Note.  This  includes,  subject to any limits  under  applicable  law,  Lender's
attorneys' fees and legal expenses whether or not there is a lawsuit,  including

                                       6


attorneys' fees and legal expenses for bankruptcy proceedings (including efforts
to  modify  or  vacate  any  automatic  stay or  injunction),  appeals,  and any
anticipated post-judgment collections services. Borrower also will pay any court
costs,  in  addition  to all other sums  provided by law. If there is a lawsuit,
Borrower  agrees  upon  Lender's  request to submit to the  jurisdiction  of any
federal or state  court  located in  Shreveport,  Louisiana.  This Note shall be
governed by and construed in accordance with the laws of the State of Louisiana.

11.      LOAN AGREEMENT.
         ---------------

     This  Note is  subject  to and  shall  be  governed  by all the  terms  and
conditions of the Credit  Agreement,  dated  September     ,  1999,  between the
                                                       ----
Borrower and Hambrecht & Quist Guaranty  Finance,  LLC, as Agent for Lender,  as
amended from time to time (the "Goodrich Credit Agreement").

12.      OUT-OF-POCKET EXPENSES.
         -----------------------

     Borrower  shall pay to Lender  the  reasonable  out-of-pocket  expenses  of
Lender  according  to the  provisions  of Section  5.12 of the  Goodrich  Credit
Agreement.

13.      SERVICE CHARGE.
         ---------------

     Since it would be impractical or extremely difficult to fix Lender's actual
damages for  collecting  and  accounting  for a late payment,  if any payment to
Lender required herein is not paid on or before its due date, Borrower shall pay
to Lender an amount equal to five percent (5%) of any such late payment (but not
less than ten dollars ($10) nor more than two-hundred and fifty dollars ($250)).

14.      GENERAL PROVISIONS.
         -------------------

     Lender may delay or forgo  enforcing  any of its rights or  remedies  under
this Note  without  losing  them.  Borrower  and any  other  person  who  signs,
guarantees  or endorses this Note may, to the extent  allowed by law,  waive any
applicable statute of limitations,  presentment, demand for payment, protest and
notice  of  dishonor.  Upon any  change in the terms of this  Note,  and  unless
otherwise  expressly stated in writing,  no party who signs this Note whether as
maker,  guarantor,  accommodation  maker or  endorser,  shall be  released  from
liability.  All such parties agree that Lender may renew, extend (repeatedly and
for any length of time) or modify this Note,  or release any party or guarantor;
or impair,  fail to realize upon or perfect  Lender's  security  interest in any
collateral  securing  this Note and take any other  action  deemed  necessary by
Lender without the consent of or notice to anyone.

15.      COLLATERAL.

more thoroughly  described in the Security Documents (as defined in the Goodrich
Credit Agreement).

PRIOR TO SIGNING THIS NOTE BORROWER READ AND  UNDERSTOOD  ALL THE  PROVISIONS OF
