EXHIBIT C

                          UNIT DESIGNATION ESTABLISHING
                            SERIES A PREFERRED UNITS

     Pursuant to the  provisions  of Section  3.2 of the  Amended  and  Restated
Operating  Agreement of Goodrich Petroleum Company,  L.L.C., a Louisiana limited
liability  company  (the  "Company"),  dated as of September  13, 1999,  as such
agreement may be amended and restated  from time to time (the "LLC  Agreement"),
the Board  hereby  submits the  following  Unit  Designation  for the purpose of
establishing  and  designating  a series of Units and fixing  the  designations,
rights and preferences thereof:

     1. Defined Terms.  Capitalized  terms defined in this Exhibit C shall have
the  meanings  given to them only for  purposes  for this  Exhibit C as the same
terms may be differently  defined elsewhere in the LLC Agreement  (including the
Exhibits thereto). Capitalized terms used in this Exhibit C that are not defined
herein shall have the meanings given thereto in the LLC Agreement.

     2. Number and  Designation.  One Million  (1,000,000)  Preferred Units are
hereby  designated as the "Series A Preferred  Units."  Three  Hundred  Thousand
(300,000)  of such  Series A  Preferred  Units will be issued by the  Company in
connection with the initial  offering of Series A Preferred  Units.  The Company
may issue  subsequent  Series A Preferred Units only if (a) such Preferred Units
are offered initially on a pro-rata basis to all then-existing holders of Series
A Preferred  Units with the proviso  that any  then-existing  holder of Series A
Preferred Units would have the right to purchase any units declined by any other
then-existing  holder of Series A Preferred  Units,  or (b) such Preferred Units
are issued pursuant to the provisions of Section 3(b) hereof.


     3. Distributions.

          (a)  Distribution  Accrual  Period.  Beginning  on the Issue  Date and
     continuing until September 30, 2002 (the  "Distribution  Accrual  Period"),
     the Company  shall  accrue on its books and  records,  but shall not pay, a
     distribution   at  an  annual  rate  of  $0.80  per  Preferred  Unit.  Such
     distribution shall be accrued quarterly,  in arrears, on March 31, June 30,
     September 30 and December 31 of each year during the  Distribution  Accrual
     Period.  The distribution  accrual for any period that is shorter or longer
     than a full  quarterly  period  shall be computed on the basis of a 360-day
     year and the actual  number of days  elapsed  (including  the first day but
     excluding the last day) occurring in the period.

          (b) Payment of Accrued Distribution.  On October 1, 2002, with respect
     to each Series A Preferred Unit outstanding on the books and records of the
     Company as of such date,  the Company will  convert the total  distribution
     accrued during the  Distribution  Accrual Period into additional  Preferred
     Units at the rate of Ten Dollars ($10.00) per Preferred Unit. No fractional
     Preferred Units will be issued, but in lieu thereof, the Company will pay a
     cash  adjustment  to the  holder in respect  of such  fractional  interest;
     provided,  however,  that no  payment  will be made in respect of such cash
     adjustment if the amount payable is less than $20.00.

                                       1


          (c) Distributions After Accrual Period.  Beginning on October 1, 2002,
     the holders of Preferred Units will be entitled to receive, when, as and if
     declared by the Board out of funds legally available  therefor,  cumulative
     cash distributions at annual rate of $1.00 per Preferred Unit. Beginning on
     October 1, 2002,  and on each October 1 thereafter,  the annual rate of the
     cash distributions payable to the holders of Series A Preferred Units shall
     increase by $0.20 per year;  provided,  that, (i) no such increase shall be
     made for any such annual  period if the closing  price for the common stock
     of    Goodrich    Petroleum    Corporation,    a    Delaware    corporation
     ("Goodrich-Delaware)  is equal to or  greater  than  $4.00  per  share  (as
     adjusted) on the last business day in September  prior to the  commencement
     of a new annual  period,  and (ii) the  annual  dividend  rate shall  never
     exceed $2.00 per  Preferred  Unit.  The  distributions  payable  under this
     paragraph  3(c)  shall be  cumulative  whether  or not in any  distribution
     period there are funds of the Company legally  available for the payment of
     such distributions and whether or not such distributions are declared.  The
     distributions payable under this paragraph 3(c) shall be payable quarterly,
     in arrears,  on March 31,  June 30,  September  30 and  December 31 of each
     year.  Notwithstanding anything to the contrary above,  distributions shall
     be paid only when,  as and if  declared  by the Board out of funds  legally
     available therefor; provided, neither the failure of the Board to declare a
     distribution  nor the  absence of funds  legally  available  to make a cash
     distribution  shall affect the Company's  obligation to make accruals.  The
     distribution  amount for any period  that is shorter or longer  than a full
     quarterly  distribution  period shall be computed on the basis of a 360-day
     year and the actual  number of days  elapsed  (including  the first day but
     excluding  the last day)  occurring  in the period for which such amount is
     payable.

     4.  Liquidation  Rights.  In the event of any liquidation,  dissolution or
winding up of the Company, whether voluntary or involuntary, distributions shall
be made to the holders of Series A Preferred Units in the following manner:

          (a) Series A Preferred. Before payment of any amount to the holders of
     Junior Units,  each holder of Series A Preferred Units shall be entitled to
     receive  from the  assets of the  Company  available  for  distribution  to
     holders  of its Units an amount  equal to  Liquidation  Preference  of each
     Series  A  Preferred  Unit  held  thereby.  If,  upon the  occurrence  of a
     liquidation,  dissolution or winding up, the assets and funds available for
     distribution  among the  holders of the Series A  Preferred  Units shall be
     insufficient to permit the payment in full of the Liquidation Preference of
     all of the outstanding Series A Preferred Units, then the entire assets and
     funds of the Company so available  shall be distributed  ratably in respect
     of the Series A Preferred Units.

          (b) Remaining  Assets.  If assets are  remaining  after payment of the
     full  preferential  amount with respect to the Series A Preferred Units set
     forth in Section 4(a), then the Company shall make distributions in respect
     of the Junior  Units  according  to the  relative  rights  and  preferences
     thereof.

          (c)  Valuation  of  Securities  and  Property.  The  Company  may only
     distribute  assets  other than cash to  holders  of the Series A  Preferred
     Units in connection with any liquidation,  dissolution or winding up of the
     Company,  on the prior written  consent of the holders of a majority of the
     Series A Preferred  Units,  and in such case, the value of the assets to be
     distributed to the holders of Series A Preferred  Units shall be determined
     in good faith by the Board.

                                       2


     5. Voting  Rights.  The holders of Series A Preferred  Units shall have no
voting  rights  with  respect to the  Series A  Preferred  Units  held  thereby;
provided,  however, that if and for so long as the Company is six months or more
in arrears in the payment of the cash  distributions  payable under Section 3(c)
hereof , the holders of Series A Preferred Units shall have the right to vote on
the election of Managers.  In such event,  each Series A Preferred Unit shall be
entitled to cast one vote.

     6. Redemption. The Series A Preferred Units may be redeemed as follows:

          (a) Redemption  Price.  The Company may, at any time, and from time to
     time,  redeem a Series A Preferred  Unit by paying to the holder thereof an
     amount equal to the Liquidation Preference.

          (b) Redemption Procedures. The following procedures shall apply to any
     redemption by the Company of the Series A Preferred  Units  pursuant to the
     preceding provisions of this Section 6:

               (i) Any redemption shall be effected by written or printed notice
     by certified  mail,  postage  prepaid,  return  receipt  requested,  to the
     holders of record of the Series A  Preferred  Units  being  redeemed,  such
     notice to be addressed to each holder at the address shown in the Company's
     records  which  notice  shall (A) specify the date of  redemption,  (B) the
     place at which  holders of the Series A  Preferred  Units  shall  surrender
     their  certificate  or  certificates  and obtain  payment of the applicable
     redemption price and (C) such other  information,  if any, as the Board may
     deem  appropriate.  Such notice  shall be given no more than 60 but no less
     than 20 days prior to the date fixed for redemption.

               (ii) On or  after  the date of  redemption  as  specified  in the
     notice  specified in Section  6(e)(i),  each holder shall  surrender to the
     Company,  at the  place  specified  in  such  notice,  its  certificate  or
     certificates  (or comply with applicable lost  certificate  provisions) for
     the Series A Preferred  Units upon payment by the Company of the applicable
     redemption price.

          (c) Pro Rata  Redemption.  Each  redemption made pursuant to Section 6
     shall be made pro  rata  with  respect  to all  then  outstanding  Series A
     Preferred Units.

          (d) No  Reissue  of Units.  Any  Series A  Preferred  Units  redeemed,
     purchased, or otherwise acquired by the Company shall be deemed retired and
     restored to the status of  undesignated  authorized  but unissued  units of
     Preferred Units and may not under any circumstances thereafter be issued or
     otherwise  disposed  of by the  Company  until such time as such Units have
     been redesignated in accordance with Section 3.2 of the LLC Agreement.

     7. Notices. Any notice required by the provisions of this Unit Designation
to be  given  to the  holders  of  Series A  Preferred  Units  shall be given in
accordance with Section 11.2 of the LLC Agreement.

                                       3


     8.  Protective  Provisions.  So long as any  Series  A  Preferred  Unit is
outstanding,  the Company shall not,  without first obtaining the consent of the
Persons  holding a majority  of the Series A Preferred  Units then  outstanding,
voting as a separate class:

          (a) amend  this  Unit  Designation  or  otherwise  alter  the  rights,
     preferences or privileges of the Series A Preferred Units;

          (b)  authorize,  create  or issue  units of any new class or series of
     Units having any preference or priority as to  distributions,  liquidation,
     redemption or assets superior to or on a parity with any such preference or
     priority of the Series A Preferred  Units,  or  authorize,  create or issue
     Units of any  class or  series  or any  bonds,  debentures,  notes or other
     obligations convertible into or exchangeable for, or having optional rights
     to  purchase,  any  Units of the  Company  having  any such  preference  or
     priority;

          (c)  reclassify  Units into Units having a  preference  over or parity
     with the Series A Preferred Units with respect to voting,  distributions or
     liquidation preferences, or any other rights and/or remedies;
