Item 2.  Acquisition or Disposition of Assets.
-------  ------------------------------------


Purchase of Assets

     On December 20, 2002, Parallel Petroleum Corporation purchased, through its
subsidiary,  Parallel,  L.P., 95% of the interest owned by nonaffiliated sellers
in producing  oil and gas  properties  located in Andrews  County,  Texas in the
Permian Basin of west Texas. The total purchase price for Parallel's interest in
the properties was  $46,075,000.00,  of which  $45,075,000  was paid in cash and
$1,000,000.00 was paid in the form of 454,545 shares of common stock of Parallel
Petroleum  Corporation.  For purposes of the  acquisition,  the common stock was
valued at $2.20 per share, the last sale price of Parallel's common stock on the
day  immediately  preceding  Parallel,  L.P.'s  execution of a purchase and sale
agreement  with the  sellers of the  properties.  Texland  Petroleum,  Inc.,  an
unaffiliated  third party,  acquired  the Seller's  remaining 5% interest in the
properties.  Parallel's  working  interest in the properties,  which consists of
approximately  3,640 gross acres,  ranges from 22% to 85%.  Texland and Parallel
Petroleum  Corporation  will co-manage the properties,  but Texland is the named
operator.

     The acquisition was initially conducted under a competitive bid process and
completed under terms of a negotiated purchase and sale agreement with JMC
Exploration, Inc. and Arkoma Star L.L.C., the sellers of the property. The
parties entered into the agreement on November 27, 2002.

     The  properties  acquired  are  currently  producing   approximately  1,150
equivalent barrels of oil per day, net to the interest acquired by Parallel. The
properties  produce from the San Andres  formation  at a depth of  approximately
4,400 feet and consist of 128 producing wells,  supported by 80  water-injection
wells situated on nine contiguous  leases containing  approximately  3,640 gross
acres.

     The cash portion of the  purchase  price was  financed  with loan  proceeds
drawn  under  a  revolving  credit  facility  provided  to  Parallel   Petroleum
Corporation  and Parallel,  L.P. by First American Bank, SSB,  Western  National
Bank and BNP Paribas.  The credit facility  provides for revolving loans subject
to a borrowing base and a monthly  commitment


                                      -2-



reduction.  The current  borrowing base is $50 million.  The monthly  commitment
reduction  commences on August 31, 2003 and continues  with a like  reduction on
the last day of each  following  month.  The  amount of the  monthly  commitment
reduction  is  determined  by  dividing  (a)  the  borrowing  base  on  the  day
immediately  preceding the date of each monthly commitment  reduction by (b) the
number of months  remaining  prior to July 1, 2008.  The borrowing  base and the
monthly  commitment  reduction  amount will be  redetermined  by the banks on or
about  April 30 and  October  31 of each  year or at other  times  requested  by
Parallel.

     The principal amount  outstanding under the revolving credit facility bears
interest at First  American  Bank's base rate or the libor rate, at the election
of Parallel Petroleum Corporation and Parallel, L.P.. Generally,  First American
Bank's  base  rate is equal  to the  prime  rate  published  in the Wall  Street
Journal,  but not less than 4.50%.  The libor rate is generally equal to the sum
of (a) the rate designated as "British Bankers  Association  Interest Settlement
Rates" and offered on one, two, three or six month interest periods for deposits
of $1,000,000,  and (b) a margin ranging from 2.25% to 2.75%, depending upon the
outstanding  principal amount of the loans. If the principal amount  outstanding
is equal to or greater than 75% of the borrowing base  established by the banks,
the margin is 2.75%. If the principal amount  outstanding is equal to or greater
than 50%, but less than 75% of the borrowing  base, the margin is 2.50%.  If the
principal amount  outstanding is less than 50% of the borrowing base, the margin
is 2.25%.

     In the case of base rate loans, interest is payable on the last day of each
month.  In the case of libor loans,  interest is payable on the last day of each
applicable interest period.

     If the total  outstanding  borrowings  under the facility are less than the
borrowing  base,  an unused  commitment  fee is  required to be paid to the bank
lenders.  The amount of the fee is .25% of the daily  average of the  unadvanced
amount of the borrowing base. The fee is payable quarterly,  commencing on March
31, 2003.

     All outstanding  principal  under the revolving  credit facility is due and
payable on December 20, 2006.  The loan is secured by  substantially  all of the
oil and gas properties  owned by Parallel  Petroleum  Corporation  and Parallel,
L.P.,  including the properties  acquired from JMC Exploration,  Inc. and Arkoma
Star, L.L.C.  Parallel,  L.L.C., a subsidiary of Parallel Petroleum Corporation,
guaranteed payment of the loans.

               reports of or about the Property,  including, without limitation,
               any  reports,  data and  conclusions  developed  pursuant  to the
               Pre-Acquisition Review, promptly after such assessment report has
               been  furnished to or obtained by Purchaser,  and Seller shall be
               permitted to discuss the contents of any such assessment  reports
               with the party who prepared such reports.

          4)   Purchaser and its employees,  agents, contractors and consultants

               that  some  or  all  of  the  Property  is  operated  by  Texland
               Petroleum, Inc and that Seller's ability to obtain access to such
               portions  of the  Property,  and the  manner  and  extent of such
               access, is subject to the cooperation of Texland Petroleum, Inc.

                                      -6-




          5)   If Purchaser  conducts any  examination or inspection  under this
               Section  or  otherwise,  then (a) such  access,  examination  and
               inspection  shall be at Purchaser's  sole risk,  cost and expense
               and Purchaser  waives and releases all claims against Seller (and
               their   affiliates  and  the  respective   directors,   officers,
               employees,  attorneys,  contractors  and agents of such  parties)
               arising in any way therefrom or in any way connected therewith or
               arising  in  connection   with  the  conduct  of  its  directors,
               officers,  employees,   attorneys,   contractors  and  agents  in
               connection  therewith and (b) Purchaser shall  indemnify,  defend
               and hold harmless Seller (and their affiliates and the respective
               officers, directors, employees, attorneys, contractors and agents
               of such  parties)  from any and all  claims,  actions,  causes of

               or in any way connected with such matters.  THE FOREGOING RELEASE
               AND  INDEMNIFICATION  SHALL  APPLY  WHETHER  OR NOT SUCH  CLAIMS,
               ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR
               EXPENSES ARE CAUSED,  OR CONTRIBUTED TO, BY (i) THE NEGLIGENCE OR
               FAULT OF SELLER OR (ii) STRICT LIABILITY.

     b)   Review.  Commencing  upon the execution of this Agreement by Purchaser
          and Seller  and ending  seven (7) days  before the  Closing  Date (the
          "Review Period"),  Purchaser and its employees, agents and contractors
          shall have the right, but not the obligation, to conduct the following
          (the Pre-Acquisition Review) at its sole cost and expense but with the
          cooperation of Seller:

         1)   To the  extent  Seller  has the  right to grant  such  rights  to
               Purchaser,  and only after notice to Seller,  to enter all or any
               part  of  the  Property  at any  reasonable  time  during  normal
               business  hours,  during  the  Review  Period,  and  to  inspect,
               inventory,  investigate (including environmental  assessments and
               evaluations),  study  and  examine  the same  and the  operations
               conducted  thereon;  provided

                                      -7-



               that  Seller  shall  have the right to  witness  and  review  the
               results  of any  such  inspections,  inventories,  investigations
               (including  environmental  assessments and evaluations),  studies
               and examination; and

          2)   To  inspect,  review  and  copy  at  reasonable  times  and  upon
               reasonable notice, all non-privileged and non-proprietary  files,
               records,  documents  and  data  related  to  the  above  matters,
               including,  but not limited to, any of the following which Seller
               may have:  Original  Well Record Files on all active wells (i.e.,
               all existing  wells  situated on the Property which have not been
               previously  plugged  and  abandoned),   Regulatory,   Accounting,
               Marketing,   Environmental,   Pipeline,   Lease,   Contract,  Fee
               Property, Right-of-Way , Maintenance, Transportation, Processing,
               Production and Engineering files and records.

     c)   Review Results.

          1)   If, as to any  portion of the  Property:  (i) there is a material
               violation  of  Environmental  Law or (ii)  there  has been such a
               substantial  deterioration  in  the  physical  condition  of  the
               Property as it existed on the Effective  Date that Purchaser will
               be unable to possess,  operate,  use or maintain  the Property in
               substantially  the same manner that the Property  was  possessed,
               operated,  used or maintained  by Seller on the Effective  Date (
               any  such  material   violation  or   substantial   deterioration
               described  (i)  and  (ii)  above  is  called  an   "Environmental
               Condition"); then, Purchaser may give written notice to Seller on
               or before the last day of the Review Period of such Environmental
               Condition.  Such notice must describe the Environmental Condition
               in reasonable  detail and include  Purchaser's  estimated cost to
               cure or remedy the Environmental  Condition.  FAILURE TO GIVE ANY
               SUCH NOTICE  WITHIN THE REVIEW PERIOD SHALL  FORECLOSE  PURCHASER
               FROM SECURING THE BENEFITS OF  SUBSECTION  9.(c)(2) AND SHALL NOT
               EXCUSE  PURCHASER FOR FAILING TO CLOSE BECAUSE OF MATTERS ARISING
               OUT OF SUCH PRE-ACQUISITION REVIEW.

                                      -8-




          2)   Within the period  between the date of receipt of such notice and
               the  Closing  Date,  Seller  may,  at its  option and in its sole
               discretion,  (i)  remedy or agree to remedy,  to a degree  agreed
               upon prior to Closing, such Environmental Condition (in the event
               current  remediation of such Environmental  Condition is required
               by a Federal,  State or local agency,  Seller and Purchaser agree
               that the condition  shall be remedied in  accordance  with and to
               the satisfaction of the appropriate agency's requirements);  (ii)
               agree with Purchaser on an adjustment to the Purchase Price which
               adjustment   shall  reflect   Purchaser's  cost  to  remedy  such
               Environmental  Condition;  (iii) remove the  affected  portion or
               portions of the  Property  from the  Property to be conveyed  and
               reduce the  Purchase  Price by the value  allocated  to  affected
               portion or portions of the Property as set forth on Exhibit D; or
               (iv) agree to  indemnify  and hold  Purchaser  harmless  from any
               third party Claims  arising out of such  Environmental  Condition
               for a period of two (2) years  after the  Closing,  to the extent
               the amount of such third party Claims, in the aggregate,  exceeds
               10% of the  Purchase  Price.  The  failure to do one of the above
               prior to the extended  Closing Date shall permit  either Party to
               terminate  this  Agreement  by  giving  written  notice  of  such
               termination  to the other on or after the extended  Closing Date.
               Upon the giving of such termination  notice,  neither Party shall
               have any  further  rights or  obligations  hereunder  except  for
               Purchaser's   obligations   and   Seller's   rights   under   the
               Confidentiality Agreement and the Indemnification  Agreement, and
               Purchaser  shall  be  entitled  to a  return  of the  Performance
               Deposit. If Seller agrees to remedy any Environmental  Condition,
               then  Purchaser  and  Seller  agree  that  all  negotiations  and
               contacts with state,  federal and local agencies for approval and
               review of such remedial action shall be made by Seller.

          3)   If the aggregate of the Environmental Conditions set forth in the
               notice are not Material,  notwithstanding  anything herein to the
               contrary,  Seller  shall  convey the  Property  to  Purchaser  at
               Closing and PURCHASER  SHALL ACCEPT THE  PROPERTY,  INCLUDING THE

                                      -9-




               PORTION(S) AFFECTED BY THE NONMATERIAL  ENVIRONMENTAL CONDITIONS,
               "WHERE IS" AND "AS IS" WITH NO RIGHT TO RECOVER  FROM  SELLER FOR
               ANY  LIABILITIES,  COSTS OR EXPENSES  RELATED TO SUCH NONMATERIAL
               ENVIRONMENTAL   CONDITIONS   (INCLUDING,    WITHOUT   LIMITATION,
               ENVIRONMENTAL  CONDITIONS  AND  DAMAGES  TO  NATURAL  RESOURCES).
               ACQUISITION  OF  THE  PROPERTY   CONTAINING   SUCH   NON-MATERIAL
               CONDITIONS  "WHERE IS" AND "AS IS" SHALL  CONSTITUTE  PURCHASER'S
               GENERAL  RELEASE  AND  AGREEMENT  TO DEFEND,  INDEMNIFY  AND HOLD
               SELLER, ITS AFFILIATES,  DIRECTORS,  OFFICERS,  EMPLOYEES, AGENTS
               AND  REPRESENTATIVES  HARMLESS  FROM  ALL  LIABILITIES,  COSTS OR
               EXPENSES RELATED TO SUCH  NON-MATERIAL  ENVIRONMENTAL  CONDITIONS
               (INCLUDING,   WITHOUT  LIMITATION,   NON-MATERIAL   ENVIRONMENTAL
               CONDITIONS AND DAMAGES TO NATURAL RESOURCES).

          4)   For purposes of this Section 9.(c),  "Material"  shall be defined
               as a cost to cure or remedy Environmental Conditions in excess of
               Ten Percent (10%) of the Purchase Price (i.e. Thousand and no/100
               Dollars

10.  Baseline Study. A Pre-Acquisition  Review assessment report of the Property
     by Purchaser,  if made and accepted in writing by Seller,  shall  establish
     the true and correct condition of the Property as of the Effective Date and
     such assessment report shall be used as the only  environmental,  safety or
     other baseline study in the event a dispute arises after Closing concerning
     the  condition of the  Property.  Seller shall have the right,  but not the
     obligation, at any time to conduct its own assessment of the Property.

11.  Disclaimers/ Acknowledgments.

          MERCHANTABILITY,  OR OTHERWISE.  Purchaser shall satisfy itself, prior
          to the Closing, as to the type,  condition,  quality and extent of the
          property  and  property  interests  which  comprise the Property it is
          receiving  pursuant to this Agreement and under this sale or exchange.
          Notwithstanding the foregoing, Seller agrees to warrant and defend the
          title to the  items of  Property  described  in  subsections  1(a)-(d)

          Purchaser shall have the right of full substitution and subrogation to

          been given the opportunity to adequately  inspect the Property for all
          purposes  prior to Closing;  (ii) Purchaser is aware that the Property
          has been used for the exploration,  development, production, treating,
          and  transporting  of oil and gas and that  physical  changes may have
          occurred  as a result of such use and that Seller has  disclosed,  and
          Purchaser is further  aware,  that there exists the  possibility  that
          there  could  have  occurred  from  such use one or more  releases  of
          hazardous substances or releases of Chemical Substances (as defined in
          Subsection 22(e)(2)),  or other pollution or contamination of or into,
          the ambient air,  surface  water,  ground  water,  or land surface and
          subsurface strata of any real property included in the Property and of
          contiguous, or a series of contiguous,  real properties not associated
          with the Property;  (iii) Purchaser has entered into this Agreement on
          the basis of its own  investigation  of the physical  condition of the
          Property and the land related  thereto  (including  the  environmental
          condition of the Property); and (iv) Purchaser, with full knowledge of
          the foregoing and after  conducting the above described  investigation
          and evaluation,  IS ACQUIRING THE PROPERTY ON A "WHERE IS" AND "AS

                                      -11-


          IS"  BASIS;  and,  except  with  respect to  Seller's  indemnification
          obligations  specified  in  Sections  22.(c)  below,   PURCHASER,   BY
          ACQUIRING  THE  PROPERTY ON A "WHERE IS" AND "AS IS" BASIS  WAIVES ANY
          OTHER RIGHTS OF INDEMNIFICATION,  CONTRIBUTION OR RECOURSE IT MAY HAVE
          AGAINST OR FROM SELLER WITH RESPECT TO THE  CONDITION OF THE PROPERTY,
          INCLUDING,  WITHOUT  LIMITATION,  THE  ENVIRONMENTAL  CONDITION OF THE
          PROPERTY AND DAMAGE TO NATURAL RESOURCES ASSOCIATED WITH THE PROPERTY.

12.  Independent Evaluation. Purchaser has made an independent evaluation of the
     Property.  SELLER MAKES NO REPRESENTATION OR WARRANTY WHATSOEVER,  EXPRESS,
     STATUTORY, OR IMPLIED, INCLUDING, BUT WITHOUT LIMITATION AS TO DESCRIPTION,
     TITLE,  VALUE,  QUALITY,   PHYSICAL  AND  ENVIRONMENTAL  CONDITION  OF  THE
     PROPERTY,  MERCHANTABILITY, OR FITNESS FOR PURPOSE OF ANY OF THE PROPERTIES
     OR THE WELLS,  EQUIPMENT,  PIPELINE  FACILITIES,  OR OTHER PROPERTY LOCATED
     THEREON OR USED IN CONNECTION  THEREWITH.  Purchaser  further  acknowledges
     that,  in  entering  into this  Agreement,  it has relied  solely  upon its
     independent  examination of the Property and public records relating to the
     Property and its independent estimates, computations,  evaluations, reports
     and studies based thereon.  Purchaser acknowledges that all information and
     data  furnished  by  Seller  is  furnished  only  as a  convenience  to the
     Purchaser.  Seller makes no warranty or  representation as to the accuracy,
     completeness  or  usefulness  of any  information  furnished to  Purchaser,
     whether furnished by Seller. SELLER, ITS OFFICERS, DIRECTORS, EMPLOYEES AND
     AGENTS ASSUME NO LIABILITY FOR THE ACCURACY,  COMPLETENESS OR USEFULNESS OF
     THE MATERIALS  FURNISHED BY SELLER.  RELIANCE ON ANY MATERIALS FURNISHED BY
     SELLER,  THE DATA UPON  WHICH  THEY ARE  BASED,  OR ANY  OTHER  INFORMATION
     FURNISHED  BY  SELLER  SHALL NOT GIVE  RISE TO ANY  CAUSE,  CLAIM OR ACTION
     AGAINST  SELLER,  OR THEIR  RESPECTIVE  DIRECTORS,  OFFICERS,  EMPLOYEES OR
     AGENTS. ANY SUCH RELIANCE SHALL BE AT PURCHASER'S SOLE RISK.

13.  Consents;  Preferential  Rights.  In the event any of the  interests  to be
     conveyed  or  transferred  to  Purchaser  as part of the  Property  (i) are
     burdened  with a  preferential  right in a third  person to  purchase  such
     interest,  or (ii) require the consent of a third party to assign  Seller's
     interest,  then the conveyance or transfer of the interest  subject to such
     preference  or consent  shall be  conditioned

                                      -12-



     up Seller's  obtaining the necessary  waiver or consent and this  Agreement
     shall not constitute an assignment or attempted  assignment thereof without
     such consent or waiver.  Provided,  however,  if such requirement for third
     party  consent is subject to an express or implied  provision to the effect
     that such consent may not be  unreasonably  withheld and Seller in its sole
     discretion,  determines that such consent is being  unreasonably  withheld,
     Seller may, at its risk, assign such interest to Purchaser.  Except for any
     liability of Seller to a third party with respect to an assignment pursuant
     to the  preceding  sentence,  Seller  shall not be liable to  Purchaser  by
     reason  of  any   inability  or  failure  to  obtain  any  such  waiver  of
     preferential  rights or consent to assignment.  The value allocated to each
     interest  on Exhibit D shall  become the price to such third party for each
     interest burdened by a preferential  right. If Seller is unable to obtain a
     required  waiver or  consent,  or  determines  that such  consent  has been
     unreasonably  withheld but elects not to assign the interest,  such failure
     to obtain the waiver or consent, or to assign the interest where consent is
     unreasonably  withheld,  shall be considered a Title Defect  subject to the
     provisions  of  subsection  14.(b)  hereof  unless  waived  in  writing  by
     Purchaser.

14.  Title.

     a)   Title Examination. PURCHASER ASSUMES THE RISK OF DESCRIPTION AND TITLE
          TO THE  PROPERTY AND AGREES TO SATISFY  ITSELF WITH  RESPECT  THERETO.
          Seller will make  available to Purchaser for  examination by Purchaser
          such title  information  and abstract  coverage as may be available in
          Seller's land and contract files.  During the period commencing on the
          date of this  Agreement and ending no later than seven (7) days before
          the Closing Date (the "Title  Examination  Period"),  Purchaser  shall
          have the right to examine,  at Seller's  offices during normal working
          hours,  all division  order and land files and records which relate to
          the  Property.  Purchaser  shall have the right to copy all such files
          made  available  for its  examination  at  Purchaser's  sole  cost and
          expense.

     b)   Title Defect.

          1)   As used in this  Agreement,  the term Title Defect shall  include
               (i) a lien or encumbrance on the Property that is

                                      -13-



               not  released at  Closing,  (ii) any defect  which  results or is
               reasonably  likely to  result  in a loss of title in Seller  such
               that  Seller's  net  revenue  interest as shown on Exhibit F with
               respect to an  interest  which is part of the  Property  is or is
               reasonably  likely to be  reduced  or  Seller's  expense  bearing
               percentage  as shown on  Exhibit F with  respect  to an  interest
               which is part of the  Property is or is  reasonably  likely to be
               increased  without  a  corresponding  increase  in  Seller's  net
               revenue interest,  or (iii) the inability of Seller to obtain the
               waiver of a  preferential  right or consent to  assignment  of an
               interest  included in the  Property or the election of Seller not
               to assign such  interest  when Seller  believes  consent is being
               unreasonably withheld as specified in Section 13 above. Purchaser
               shall give Seller  written  notice of such title  defect at least
               seven  (7) days  before  the  Closing  Date,  together  with full
               particulars  relating thereto.  PURCHASER SHALL BE DEEMED TO HAVE
               WAIVED ALL TITLE DEFECTS AND ANY OTHER DEFECT OF WHICH SELLER HAS
               NOT BEEN GIVEN WRITTEN  NOTICE AT LEAST FOURTEEN (14) DAYS BEFORE
               THE CLOSING DATE.  Any title defects must be, in the aggregate in
               excess of a loss of One Percent (1%) of the Purchase  Price (i.e.
               $ ) before any adjustment  will be made in the Purchase Price and
               an adjustment  shall only be made for the amount in excess of One
               Percent (1%) of the  Purchase  Price.  In the event  Seller's net
               revenue  interest is or is  reasonably  likely to be increased or
               its working  interest is or is reasonably  likely to be decreased
               without a corresponding  decrease in net revenue  interest,  then

          2)   Interests  which have Title  Defects  shall be excluded  from the

               allocated  to such  interests  on Exhibit D unless:  (i) prior to
               Closing,  the basis for the Title  Defects  has been  removed  by

               obligation  to obtain such  removal);  (ii)  Purchaser  agrees to
               accept the  affected  interest "as is" without a reduction in the

               reduction  in the  Purchase  Price;  or  (iv)  Seller  agrees  to
               indemnify  Purchaser  against  losses,   costs,   expenses,   and
               liabilities  with respect to such Title Defect to the extent they
               exceed, in the aggregate, One Percent (1%) of the Purchase Price.
               If the Parties  cannot agree prior to Closing upon an  adjustment
               to the Purchase Price for interests which are burdened by a title
               defect  and  which  are  to  be  acquired  by  Purchaser  with  a
               reduction.  in the  Purchase  Price,  then either  Party may give
               written  notice to the other Party to terminate  this  Agreement.
               Moreover,  the  right  to  terminate  provided  in the  preceding
               sentence  shall  not  apply if Seller  removes  the title  defect
               pursuant to subsection (i) or indemnifies  Purchaser  pursuant to
               subsection  (iv) or if  Purchaser  accepts the  interest  "as is"

          royalty  owners and without  the  benefit of a fieldwide  unitization.
          Purchaser hereby  acknowledges that Seller has disclosed the existence
          of  the  various  leaseline  wells  to  Purchaser.   Purchaser  hereby
          stipulates   and  agrees  any  existing,   potential,   or  contingent
          liabilities  relating to the drilling and subsequent operation of said
          leaseline  wells shall not be a Title Defect under this  Agreement and
          shall not in any event be the  basis  for a claim by  Purchaser  for a
          reduction of the Purchase Price.

               Parallel  Petroleum  Corporation  and its officers and  directors
               concerning  the  purchase  and  the  Shares  and  to  obtain  any

"PLP",  "PPC" and "Syndication  Agent" shall have the meanings  indicated above.
When used herein the following terms shall have the following meanings:

     Adjusted Consolidated Net Worth shall mean PPC's consolidated stockholders'
equity,  as determined in accordance with GAAP,  excluding the cumulative effect
of any change in accounting principles after April 1, 2002 and the after-tax net
effect of any  non-recurring  non-cash  charges after April 1, 2002,  including,
without  limitation,  any charges  under  Financial  Accounting  Standard  Board
Statement No. 144, as amended, supplemented or modified from time to time.




     Advance means a borrowing hereunder (i) made to Borrowers by some or all of
the Lenders on the same  Borrowing  Date, or (ii)  converted or continued by the
Lenders on the same date of conversion or  continuation,  consisting,  in either
case, of the aggregate  amount of the several Loans of the same type and, in the
case of LIBOR Loans, for the same Interest Period.

     Affiliate  means any Person which,  directly or  indirectly,  controls,  is
controlled  by or is under  common  control with the  relevant  Person.  For the
purposes of this definition,  "control"  (including,  with correlative meanings,
the terms "controlled by" and "under common control with"), as used with respect
to any Person,  shall mean a member of the board of  directors,  a partner or an
officer  of such  Person,  or any other  Person  with  possession,  directly  or
indirectly,  of the power to direct or cause the direction of the management and
policies of such Person,  through the  ownership (of record,  as trustee,  or by
proxy) of voting  shares,  partnership  interests  or voting  rights,  through a
management contract or otherwise.  Any Person owning or controlling  directly or
indirectly  ten percent or more of the voting shares,  partnership  interests or
voting rights,  or other equity interest of another Person shall be deemed to be
an Affiliate of such Person.

     Acquisition means the acquisition contemplated by that certain Purchase and
Sale Agreement dated as of November 27, 2002, by and among JMC Exploration, Inc.
and Arkoma Star L.L.C., as Sellers,  and Parallel,  L.P., and Texland Petroleum,
Inc., as  Purchasers,  as amended by Letter  Agreement  dated December 11, 2002,

     Assignment and  Acceptance  means a document  substantially  in the form of
Exhibit "E" hereto.

     Available  Commitment  means,  at any time, the  Commitment  then in effect
minus the Total Outstandings.

     Base Rate shall mean, as of any date, a rate of interest per annum equal to
the higher of (A) four and one-half  percent  (4.50%),  (B) the fluctuating rate
published  in the Money  Rates  section of The Wall  Street  Journal as the U.S.
"prime rate",  or (C) the sum of the Federal Funds  Effective Rate for such date
plus one-half of one percent (.50%) per annum. If the Money Rates section of The
Wall Street Journal  contains

                                      -2-


more than one U.S.  "prime  rate",  then the "prime  rate" for  purposes of this
definition  shall be the higher of said rates. If the Money Rates section of The
Wall Street  Journal does not have a rate  designated by it as its "prime rate",
then the "prime rate" shall be deemed to be the fluctuating rate of interest per
annum which is the general  reference rate designated by Agent as its "reference
rate",  "base rate" or other  similar rate and which is comparable to the "prime
rate" as described above. The Base Rate is used by Agent as a general  reference
rate  of  interest,   taking  into  account  such  factors  as  Agent  may  deem
appropriate,  it being  understood that it is not necessarily the lowest or best
rate actually charged to any customer and that Agent may make various commercial
or other loans at rates of interest  having no  relationship  to such rate. Each
change in the Base Rate shall become effective without prior notice to Borrowers
automatically  as of the  opening of  business on the date of such change in the
Base Rate.

are legally  open for business in Midland,  Texas and New York,  New York and on
which dealings in United States  dollars are carried on in the London  interbank
market, and (ii) for all other purposes a day (other than Saturdays and Sundays)
on which banks are legally open for business in Midland, Texas.

     Change  of  Management  shall  occur  if  a  majority  of  the  individuals
comprising the Board of Directors of PPC as of the Effective Date shall

                                      -3-

Advances hereunder in amounts not exceeding,  in the aggregate,  an amount equal
to such  Lender's  Commitment  Percentage  times the total  Commitment as of any
date.  The  Commitment of each Lender  hereunder  shall be adjusted from time to
time to reflect  assignments  made by such Lender pursuant to Section 29 hereof.
Each  reduction in the  Commitment  shall result in a Pro Rata reduction in each
Lender's Commitment.

     Commitment  Percentage  means  for each  Lender  the  percentage  set forth
opposite  the  Lender's  name  on the  signature  page  hereto.  The  Commitment
Percentage  of each  Lender  hereunder  shall be  adjusted  from time to time to

     Consolidated Cash Flow means PPC's  Consolidated Net Income for each fiscal

     Period selected by Borrowers  pursuant to Section 4 hereof to be applicable
     thereto.  Upon  receipt of such  Notice,  Agent  shall  advise  each Lender
     thereof; provided, that if the Lenders have received at least one (1) day's
     notice of such  Advance  prior to funding of a Base Rate Loan,  or at least
     three (3) days'  notice of each  Advance  prior to funding in the case of a

                                      -14-




     available to the Borrowers at the same office, in like funds, the aggregate
     amount of such requested Advance.  Neither Agent nor any Lender shall incur
     any  liability  to the  Borrowers  in acting  upon any Notice of  Borrowing
     referred to above which Agent or such Lender believes in good faith to have
     been given by a duly  authorized  officer  or other  person  authorized  to
     borrow on behalf of Borrowers or for  otherwise  acting in good faith under
     this Section 2(c). Upon funding of Advances by Lenders and such funds being
     made available to Borrowers in accordance with this Agreement,  pursuant to

     forth, the Agent shall from time to time during the period beginning on the
     Effective  Date and  ending on the  Maturity  Date upon  request  of either
     Borrower issue standby Letters of Credit for the account of either Borrower
     (the  "Letters  of  Credit") in such face  amounts as either  Borrower  may
     request,  but not to  exceed  in the  aggregate  face  amount  at any  time
     outstanding the sum of One Million and No/100 Dollars ($1,000,000.00).  The
     face amount of all Letters of Credit issued and outstanding hereunder shall
     be considered as Advances on the Commitment for Borrowing Base purposes and
     all  payments  made by the  Agent  on  such  Letters  of  Credit  shall  be
     considered as Advances under the Notes.  Each Letter of Credit used for the
     account  of  either  Borrower  hereunder  shall  (i) be in  favor  of  such
     beneficiaries as are  specifically  requested by such Borrower for purposes
     of securing such  Borrower's  obligations  associated  with its oil and gas
     operations  and  activities,  or securing such  Borrower's  obligations  in
     connection   with  Rate  Management   Transactions   permitted  under  this
     Agreement,  (ii) have an  expiration  date not exceeding the earlier of (a)
     one year or (b) the Maturity  Date,  and (iii) contain such other terms and
     provisions  as may be  required by Agent.  Each  Lender  (other than Agent)
     agrees  that,  upon  issuance of any Letter of Credit  hereunder,  it shall
     automatically  acquire a participation in the Agent's  liability under such
     Letter of Credit in an amount equal to such Lender's Commitment  Percentage
     of such  liability,  and each  Lender  (other  than  Agent)  thereby  shall
     absolutely,  unconditionally and irrevocably assume, as primary obligor and
     not as surety, and shall be  unconditionally  obligated to Agent to pay and
     discharge when due, its Commitment  Percentage of Agent's  liability  under
     such  Letter of  Credit.  The  Borrowers  hereby,  jointly  and  severally,
     unconditionally agree to pay and reimburse the Agent for the

                                      -15-



     amount of each  demand for  payment  under any Letter of Credit  that is in
     compliance  with the provisions of any such Letter of Credit at or prior to
     the date on which  payment  is to be made by the  Agent to the  beneficiary
     thereunder,  without presentment,  demand,  protest or other formalities of
     any kind.  Upon receipt from any beneficiary of any Letter of Credit of any
     demand for payment  under such Letter of Credit,  the Agent shall  promptly
     notify the  Borrowers of the demand and the date upon which such payment is
     to be made by the Agent to such  beneficiary  in  respect  of such  demand.
     Forthwith  upon  receipt of such  notice  from the Agent,  Borrowers  shall
     advise the Agent  whether or not  Borrowers  intend to borrow  hereunder to
     finance  their  obligations  to reimburse  the Agent,  and if so,  submit a
     Notice of Borrowing as provided in Section 2(c) hereof.  If Borrowers  fail
     to so advise Agent and thereafter fail to reimburse  Agent, the Agent shall
     notify  each  Lender of the demand  and the  failure  of the  Borrowers  to
     reimburse  the Agent,  and each Lender  shall  reimburse  the Agent for its
     Commitment  Percentage of each such draw paid by the Agent and unreimbursed
     by the Borrowers.  All such amounts paid by Agent and/or  reimbursed by the
     Lenders  shall be treated as an Advance or Advances  under the  Commitment,
     which Advances shall be immediately due and payable and shall bear interest
     at the Maximum Rate.

          (e) Procedure for Obtaining Letters of Credit.  The amount and date of
     issuance,  renewal,  extension or reissuance of a Letter of Credit pursuant
     to the Lenders'  commitments  above in Section 2(d) shall be  designated by
     either  Borrower's  written  request  delivered to Agent at least three (3)
     Business  Days prior to the date of such  issuance,  renewal,  extension or

     request for a Letter of Credit,  the  Borrower  making such  request  shall
     execute and deliver to the Agent an application  and agreement with respect
     to the Letter of Credit,  said  application and agreement to be in the form
     used by the Agent. The Agent shall not be obligated to issue, renew, extend
     or reissue  such Letter of Credit if (A) the amount  thereon  when added to
     the face amount of the outstanding Letters of Credit plus any Reimbursement
     Obligations  exceeds One Million and No/100 Dollars  ($1,000,000.00) or (B)
     the amount  thereof when added to the Total  Outstandings  would exceed the
     Commitment.  Borrowers,  jointly and severally,  agree to pay the Agent for
     the  benefit of the Lenders  commissions  for issuing the Letters of Credit
     (calculated separately for each Letter of Credit) in an amount equal to the
     greater of (i) the LIBOR  Margin then in effect per annum times the

                                      -16-



     maximum  face  amount of the Letter of Credit  (calculated  on the basis of
     actual days elapsed or a year  consisting of 360 days) or (ii) $500.00.  In
     addition,  Borrowers,  jointly and severally, agree to pay to the Agent for
     its own account an  additional  commission  of  one-quarter  of one percent
     (.25%)  times the maximum  face amount of such Letter of Credit for issuing
     each such Letter of Credit.  Such commissions shall be payable prior to the
     issuance of each Letter of Credit and thereafter on each  anniversary  date
     of such issuance while such Letter of Credit is outstanding.

          (f) Voluntary  Reduction of  Commitment.  Subject to the provisions of
     Section 5(e) hereof,  Borrowers may at any time, or from time to time, upon
     not less than  three (3)  Business  Days'  prior  written  notice to Agent,
     reduce  or  terminate  the  Commitment;  provided,  however,  that (i) each
     reduction in the Commitment must be in the amount of $1,000,000 or more, in
     increments of $100,000 and (ii) each  reduction  must be  accompanied  by a
     prepayment  of the Notes in the amount by which the  outstanding  principal
     balance of the Notes  exceeds the  Commitment  as reduced  pursuant to this
     Section 2(f).

          (g) Mandatory Commitment Reductions.

               (i) Sale of Assets. The Borrowing Base shall be reduced from time
          to time by the amount of any  prepayment  required  by  Section  12(r)
          hereof upon the sale of assets.  If, as a result of any such reduction
          in  the  Borrowing  Base,  the  Total  Outstandings  ever  exceed  the
          Borrowing  Base then in effect,  Borrowers  shall  make the  mandatory
          prepayment of principal required pursuant to Section 9(b) hereof.

               (ii)  Monthly  Commitment  Reductions.  The  Commitment  shall be
          reduced as of the last day of each month  commencing  August 31, 2003,
          by an amount  determined  by the Lenders  pursuant to Section 7 hereof
          (the "Monthly  Commitment  Reduction").  Subject to Lenders'  right to
          redetermine  the Monthly  Commitment  Reduction  pursuant to Section 7
          hereof, the Monthly Commitment Reduction on August 31, 2003 and on the
          last day of each month thereafter,  shall be in an amount equal to the
          amount of the Borrowing Base on the day immediately preceding the date
          of each such  Monthly  Commitment  Reduction  divided by the number of
          months then  remaining  prior to July 31, 2008.  If as a result of any
          such Monthly Commitment Reduction, the Total Outstandings

                                      -17-



          ever exceed the Commitment  then in effect,  Borrowers  shall make the
          mandatory  prepayment of principal  required  pursuant to Section 9(b)
          hereof.

          (h) Several  Obligations.  The  obligations  of the Lenders  under the
     Commitment are several and not joint.  The failure of any Lender to make an
     Advance required to be made by it shall not relieve any other Lender of its
     obligation to make its Advance,  and no Lender shall be responsible for the
     failure  of any other  Lender to make the  Advance to be made by such other
     Lender.  No Lender shall be required to lend hereunder any amount in excess
     of its legal lending limit.

          (i) Type and Number of Advances.  Any Advance on the Commitment may be
     a Base Rate Loan or a LIBOR Loan, or a combination  thereof, as selected by
     the  Borrower  pursuant to Section 4 hereof.  The total  number of Tranches
     which may be outstanding at any time shall never exceed three (3).

     3. Notes Evidencing  Loans. The loans described above in Section 2 shall be
evidenced by promissory notes of Borrower as follows:

          (a) Form of Notes.  The Revolving Loan shall be evidenced by a Note or
     Notes in the aggregate face amount of  $100,000,000,  and the Note or Notes
     shall be in the form of Exhibit  "B" hereto  with  appropriate  insertions.
     Notwithstanding  the face amount of the Notes,  the actual principal amount
     due from the  Borrowers to Lenders on account of the Notes,  as of any date
     of computation,  shall be the sum of Advances then and theretofore  made on
     account thereof,  less all principal  payments actually received by Lenders
     in collected funds with respect thereto. Although the Notes may be dated as
     of the Effective  Date,  interest in respect  thereof shall be payable only
     for the period  during which the loans  evidenced  thereby are  outstanding
     and, although the stated amount of the Notes may be higher, the Notes shall
     be enforceable,  with respect to Borrowers' obligation to pay the principal
     amount thereof,  only to the extent of the unpaid  principal  amount of the
     Revolving  Loans.  Irrespective  of the face amount of the Notes, no Lender
     shall ever be obligated to advance on the  Commitment  any amount in excess
     of its Commitment then in effect.

          (b) Issuance of Additional Notes. At the Effective Date there shall be
     outstanding  Note or Notes in the  aggregate  face  amount of

                                      -18-




     $100,000,000  payable to the order of Lenders.  From time to time new Notes
     may be issued to other  Lenders  as such  Lenders  become  parties  to this
     Agreement.  Upon request from Agent, Borrowers shall execute and deliver to
     Agent any such new or additional  Notes. From time to time as new Notes are
     issued the Agent shall  require  that each Lender  exchange its Note(s) for
     newly  issued  Note(s)  to  better  reflect  the  extent  of each  Lender's
     Commitments hereunder.

          (c) Interest Rates.  The unpaid  principal  balance of the Notes shall
     bear interest from time to time as set forth in Section 4 hereof.

          (d)  Payment of  Interest.  Interest  on the Notes shall be payable on
     each Interest Payment Date.

          (e) Payment of Principal.  Principal of the  Revolving  Loans shall be
     due and payable to the Agent for the ratable  benefit of the Lenders on the
     Maturity  Date  unless  earlier  due in whole or in part as a result  of an
     acceleration  of the amount due or  pursuant  to the  mandatory  prepayment
     provisions of Section 9(b) hereof.

          (f)  Payment to  Lenders.  Each  Lender's  Pro Rata Part of payment or
     prepayment  of the Loans shall be directed by wire  transfer to such Lender
     by the Agent at the  address  provided  to the Agent  for such  Lender  for
     payments no later than 2:00 p.m., Midland,  Texas, time on the Business Day
     such payments or prepayments are deemed  hereunder to have been received by
     Agent; provided, however, in the event that any Lender shall have failed to
     make an  Advance  as  contemplated  under  Section 2 hereof (a  "Defaulting
     Lender")  and the Agent or another  Lender or Lenders  shall have made such
     Advance,  payment  received  by Agent for the  account  of such  Defaulting
     Lender or Lenders shall not be  distributed  to such  Defaulting  Lender or
     Lenders  until such  Advance or Advances  shall have been repaid in full to
     the Lender or Lenders who funded such Advance or  Advances.  Any payment or
     prepayment received by Agent at any time after 12:00 noon, Midland,  Texas,
     time on a Business  Day shall be deemed to have been  received  on the next
     Business Day. Interest shall cease to accrue on any principal as of the end
     of the day  preceding  the  Business  Day on  which  any  such  payment  or
     prepayment  is deemed  hereunder to have been  received by Agent.  If Agent
     fails to transfer  any  principal  amount to any Lender as provided  above,
     then Agent shall promptly direct such principal  amount by wire transfer to
     such Lender.


                                      -19-



          (g) Sharing of  Payments,  Etc. If any Lender shall obtain any payment
     (whether  voluntary,  involuntary,  or  otherwise) on account of the Loans,
     (including,  without limitation, any set-off) which is in excess of its Pro
     Rata Part of  payments  on the Loans,  as the case may be,  obtained by all
     Lenders,   such  Lender  shall   purchase   from  the  other  Lenders  such
     participation  as shall be  necessary  to cause such  purchasing  Lender to
     share the excess payment pro rata with each of them;  provided that, if all
     or any portion of such excess  payment is  thereafter  recovered  from such
     purchasing  Lender,  the purchase shall be rescinded and the purchase price
     restored to the extent of the recovery.  Borrowers agree that any Lender so
     purchasing a  participation  from another  Lender  pursuant to this Section
     may, to the fullest extent permitted by law,  exercise all of its rights of
     payment  (including the right of offset) with respect to such participation
     as fully as if such Lender were the direct  creditor  of  Borrowers  in the
     amount of such participation.

          (h)  Non-Receipt  of Funds by the Agent.  Unless the Agent  shall have
     been notified by a Lender or the Borrowers  (the "Payor") prior to the date
     on which such Lender is to make  payment to the Agent of the  proceeds of a
     Loan to be made by it hereunder  or Borrowers  are to make a payment to the
     Agent for the  account  of one or more of the  Lenders,  as the case may be
     (such payment being herein  called the  "Required  Payment"),  which notice
     shall be effective upon receipt, that the Payor does not intend to make the
     Required  Payment to the  Agent,  the Agent may  assume  that the  Required
     Payment has been made and may, in reliance upon such  assumption (but shall
     not be required  to),  make the amount  thereof  available  to the intended
     recipient  on such date and, if the Payor has not in fact made the Required
     Payment to the Agent,  the recipient of such payment shall, on demand,  pay
     to the Agent the amount made available to it together with interest thereon
     in  respect  of the  period  commencing  on the date such  amount  was made
     available by the Agent until the date the Agent recovers such amount at the
     rate applicable to such portion of the applicable Loan.

     4. Interest Rates.

          (a) Options.

               (i) Base Rate Loans.  On all Base Rate Loans  Borrowers  agree to
          pay interest on the Notes calculated


                                      -20-




          on the basis of the actual days  elapsed in a year  consisting  of 365
          days, or if appropriate, 366 days with respect to the unpaid principal
          amount of each Base Rate Loan from the date the  proceeds  thereof are
          made available to Borrowers until maturity (whether by acceleration or
          otherwise), at a varying rate per annum equal to the lesser of (i) the
          Maximum Rate (defined herein),  or (ii) the Base Rate.  Subject to the
          provisions of this  Agreement as to  prepayment,  the principal of the
          Notes  representing  Base Rate Loans shall be payable as  specified in
          Section 3(e) hereof and the interest in respect of each Base Rate Loan
          shall be payable on each  Interest  Payment Date  applicable  thereto.
          Past due  principal  and,  to the extent  permitted  by law,  past due
          interest  in  respect to each Base Rate  Loan,  shall  bear  interest,
          payable on demand, at a rate per annum equal to the Default Rate.

               (ii)  LIBOR  Loans.  On all LIBOR  Loans  Borrowers  agree to pay
          interest calculated on the basis of a year consisting of 360 days with
          respect  to the  unpaid  principal  amount of each LIBOR Loan from the
          date the  proceeds  thereof  are made  available  to  Borrowers  until
          maturity (whether by acceleration or otherwise), at a varying rate per
          annum equal to the lesser of (i) the Maximum  Rate,  or (ii) the LIBOR
          Rate.  Subject to the  provisions  of this  Agreement  with respect to
          prepayment,  the  principal of the Notes shall be payable as specified
          in Section  3(e) hereof and the  interest  with  respect to each LIBOR
          Loan  shall  be  payable  on each  Interest  Payment  Date  applicable
          thereto.  Past due principal and, to the extent permitted by law, past
          due interest  shall bear  interest,  payable on demand,  at a rate per
          annum equal to the Default Rate. Upon three (3) Business Days' written
          notice  prior to the  making by the  Lenders of any LIBOR Loan (in the
          case of the initial  Interest Period  therefor) or the expiration date
          of each succeeding Interest Period (in the case of subsequent Interest
          Periods  therefor),  Borrowers  shall  have  the  option,  subject  to
          compliance by Borrowers with all of the provisions of this  Agreement,
          as long as no Event of Default exists, to specify whether the Interest
          Period  commencing on any such date shall be a one (1), two (2),

                                      -21-



          three (3) or six (6) month  period.  If Agent shall not have  received
          timely  notice  of a  designation  of such  Interest  Period as herein
          provided,  Borrowers  shall be deemed to have  elected to convert  all
          maturing   LIBOR  Loans  to  Base  Rate  Loans.

          (b)  Interest  Rate  Determination.  The Agent  shall  determine  each
     interest  rate  applicable  to the Loans  hereunder.  The Agent  shall give
     prompt  notice to  Borrowers  and the  Lenders of each rate of  interest so
     determined and its determination thereof shall be conclusive absent error.

          (c)  Conversion  Option.  Borrowers may elect from time to time (i) to
     convert  all or any part of its LIBOR  Loans to Base  Rate  Loans by giving
     Agent  irrevocable  notice of such  election in writing prior to 10:00 a.m.
     (Midland,  Texas time) on the conversion date and such conversion  shall be
     made on the requested conversion date, provided that any such conversion of
     a LIBOR Loan shall only be made on the last day of the Interest Period with
     respect thereof,  (ii) to convert all or any part of its Base Rate Loans to
     LIBOR Loans by giving the Agent irrevocable written notice of such election
     three  (3)  Business  Days  prior  to  the  proposed  conversion  and  such
     conversion  shall be made on the  requested  conversion  date  or,  if such
     requested  conversion  date is not a Business  Day, on the next  succeeding
     Business Day. Any such conversion shall not be deemed to be a prepayment of
     any of the loans for purposes of this Agreement or the Notes.

          (d)  Recoupment.  If at any  time  the  applicable  rate  of  interest
     selected  pursuant to Sections  4(a)(i) or 4(a)(ii)  above shall exceed the
     Maximum  Rate,  thereby  causing the interest on the Notes to be limited to
     the Maximum  Rate,  then any  subsequent  reduction in the interest rate so
     selected or subsequently  selected shall not reduce the rate of interest on
     the Notes below the Maximum Rate until the total amount of interest accrued
     on the Notes equals the amount of interest  which would have accrued on the
     Notes if the rate or rates selected  pursuant to Sections  4(a)(i) or (ii),
     as the case may be, had at all times been in effect.

          (e) Interest Rates Applicable After Default.  Notwithstanding anything
     to the contrary  contained in this Section 4, during the  continuance  of a
     Default or an Event of Default the Majority  Lenders may, at their  option,
     by notice  from  Agent to  Borrowers  (which


                                      -22-



     notice may be revoked at the option of the Majority Lenders notwithstanding
     the provisions of Section 15 hereof,  which requires all Lenders to consent
     to changes  in  interest  rates)  declare  that no Advance  may be made as,
     converted into, or continued as a LIBOR Loan.  During the continuance of an
     Event of Default,  the Majority  Lenders,  may, at their option,  by notice
     from  Agent to  Borrowers  (which  notice  may be  revoked at the option of
     Majority Lenders notwithstanding the provisions of Section 15 hereof, which
     requires all Lenders to consent to changes in interest  rates) declare that
     (i) each LIBOR Loan shall bear interest for the remainder of the applicable
     Interest  Period at the rate otherwise  applicable to such Interest  Period
     plus four  percent  (4%) per annum and (ii) each Base Rate Loan  shall bear
     interest at the rate otherwise applicable to such Interest Period plus four
     percent (4%),  provided that, during the continuance of an Event of Default
     under  Section  14(f) or 14(g),  the interest rate set forth in clauses (i)
     and (ii) above shall be  applicable  to all  outstanding  Loans without any
     election or action on the part of the Agent or any Lender.

     5. Special Provisions Relating to Loans.

          (a)  Unavailability  of Funds or Inadequacy  of Pricing.  In the event
     that,  in connection  with any proposed  LIBOR Loan,  the Agent  reasonably
     determines,  which  determination  shall,  absent manifest error, be final,
     conclusive  and binding upon all parties,  due to changes in  circumstances
     since the date hereof, adequate and fair means do not exist for determining
     the LIBOR Rate or such rate will not  accurately  reflect  the costs to the
     Lenders of funding a LIBOR Loan for such Interest  Period,  the Agent shall
     give notice of such determination to Borrowers and the Lenders,  whereupon,
     until the Agent notifies  Borrowers and the Lenders that the  circumstances
     giving rise to such  suspension no longer  exist,  the  obligations  of the
     Lenders  to make,  continue  or  convert  Loans  into a LIBOR Loan shall be
     suspended,  and all Loans to Borrowers  shall be Base Rate Loans during the
     period of suspension.

          (b)  Change  in  Laws.  If at any time  any new law or any  change  in
     existing  laws or in the  interpretation  of any new or existing laws shall
     make it  unlawful  for any Lender to make or  continue  to maintain or fund
     LIBOR Loans hereunder,  then such Lender shall promptly notify Borrowers in
     writing and such  Lender's  obligation  to make,  continue or convert Loans
     into LIBOR Loans under this  Agreement  shall be  suspended  until it is no
     longer

                                      -23-



     unlawful for such Lender to make or maintain  LIBOR Loans.  Upon receipt of
     such notice,  Borrowers shall either repay the outstanding LIBOR Loans owed
     to such Lender,  without  penalty,  on the last day of the current Interest
     Periods (or, if any Lender may not  lawfully  continue to maintain and fund
     such LIBOR Loans,  immediately),  or Borrowers may convert such LIBOR Loans
     at such appropriate time to Base Rate Loans.

          (c) Increased Cost or Reduced Return.

               (i) If,  after the date hereof,  the  adoption of any  applicable
          law, rule, or regulation,  or any change in any applicable  law, rule,
          or regulation,  or any change in the  interpretation or administration
          thereof by any  governmental  authority,  central  bank, or comparable
          agency charged with the interpretation or administration  thereof,  or
          compliance by any Lender with any request or directive (whether or not
          having the force of law) of any such governmental  authority,  central
          bank, or comparable agency:

                    (A) shall  subject  such Lender to any tax,  duty,  or other
               charge  with  respect  to any  LIBOR  Loans,  its  Notes,  or its
               obligation  to make LIBOR Loans,  or change the basis of taxation
               of any amounts payable to such Lender under this Agreement or its
               Notes in respect of any LIBOR Loan  (other than  franchise  taxes
               and taxes  imposed on or  measured  by the  overall net income of
               such Lender);

                    (B) shall impose,  modify,  or deem  applicable any reserve,
               special deposit,  assessment,  or similar requirement (other than
               reserve   requirements,   if  any,  taken  into  account  in  the
               determination  of the LIBOR Rate)  relating to any  extensions of
               credit  or  other  assets  of,  or any  deposits  with  or  other
               liabilities  or  commitments  of,  such  Lender,   including  the
               Commitment of such Lender hereunder; or

                                      -24-




                    (C) shall  impose on such Lender or on the London  interbank
               market any other condition  affecting this Agreement or its Notes
               or  any  of  such   extensions  of  credit  or   liabilities   or
               commitments;

          and the result of any of the foregoing is to increase the cost to such
          Lender of making,  converting  into,  continuing,  or maintaining  any
          LIBOR Loan or to reduce any sum received or  receivable by such Lender
          under this Agreement or its Notes with respect to any LIBOR Loan, then
          Borrowers shall pay to such Lender on demand such amount or amounts as
          will  reasonably  compensate  such Lender for such  increased  cost or
          reduction. If any Lender requests compensation by Borrowers under this
          Section 5(c),  Borrowers may, by notice to such Lender (with a copy to
          Agent),  suspend  the  obligation  of such  Lender to make or continue
          LIBOR Loans, or to convert all or part of the Base Rate Loans owing to
          such Lender to LIBOR Loans,  until the event or condition  giving rise
          to such request  ceases to be in effect (in which case the  provisions
          of Section 5(c) shall be  applicable);  provided that such  suspension
          shall not affect the right of such Lender to receive the  compensation
          so requested.

               (ii) If, after the date hereof,  any Lender shall have reasonably
          determined   that  the  adoption  of  any  applicable  law,  rule,  or
          regulation  regarding capital adequacy or any change therein or in the
          interpretation   or   administration   thereof  by  any   governmental
          authority,  central  bank,  or  comparable  agency  charged  with  the
          interpretation or administration  thereof, or any request or directive
          regarding capital adequacy (whether or not having the force of law) of
          any such governmental  authority,  central bank, or comparable agency,
          has or would  have the  effect of  reducing  the rate of return on the
          capital of such Lender or any corporation controlling such Lender as a
          consequence  of such Lender's  obligations  hereunder to a level below
          that which such Lender or such corporation could have achieved but for
          such   adoption,   change,   request,   or   directive   (taking  into
          consideration its policies with respect to capital

                                      -25-



          adequacy),  then from time to time upon demand  Borrowers shall pay to
          such  Lender  such  additional  amount or amounts  as will  reasonably
          compensate such Lender for such reduction.

               (iii) Each Lender shall  promptly  notify  Borrowers and Agent of
          any event of which it has knowledge,  occurring after the date hereof,
          which  will  entitle  such  Lender to  compensation  pursuant  to this
          Section  5(c)  and  will  designate  a  separate  lending  office,  if
          applicable, if such designation will avoid the need for, or reduce the
          amount of, such  compensation  and will not,  in the  judgment of such
          Lender,  be  otherwise  disadvantageous  to it.  Any  Lender  claiming
          compensation  under this Section 5(c) shall  furnish to Borrowers  and
          Agent a statement setting forth the additional amount or amounts to be
          paid to it  hereunder  which  shall be  conclusive  in the  absence of
          manifest  error. In determining  such amount,  such Lender may use any
          reasonable averaging and attribution methods.

               (iv) Any Lender  giving  notice to  Borrowers  through  the Agent
          pursuant to Section 5(c) shall give to Borrowers a statement signed by
          an officer of such Lender setting forth in reasonable detail the basis
          for, and the calculation of such additional cost,  reduced payments or
          capital  requirements,  as the case may be, and the additional amounts
          required to compensate such Lender therefor.

               (v) Within five (5) Business  Days after  receipt by Borrowers of
          any notice  referred to in Section  5(c),  Borrowers  shall pay to the
          Agent  for  the  account  of  the  Lender  issuing  such  notice  such
          additional  amounts as are required to compensate  such Lender for the
          increased cost,  reduced  payments or increased  capital  requirements
          identified therein, as the case may be.

          (d) Discretion of Lender as to Manner of Funding.  Notwithstanding any
     provisions of this Agreement to the contrary, each Lender shall be entitled
     to fund  and  maintain  its  funding  of all or any part of its Loan in any
     manner it sees fit, it being understood,  however, that for the purposes of
     this Agreement all

                                      -26-




     determinations  hereunder  shall  be made as if each  Lender  had  actually
     funded and  maintained  each LIBOR Loan  through  the  purchase of deposits
     having a  maturity  corresponding  to the last day of the  Interest  Period
     applicable  to  such  LIBOR  Loan  and  bearing  an  interest  rate  at the
     applicable interest rate for such Interest Period.

          (e)  Breakage  Fees.  Without  duplication  under any other  provision
     hereof, if any Lender incurs any loss, cost or expense  including,  without
     limitation,  any  loss  of  profit  and  loss,  cost,  expense  or  premium
     reasonably  incurred  by  reason of the  liquidation  or  re-employment  of
     deposits  or other funds  acquired  by such Lender to fund or maintain  any
     LIBOR Loan or the relending or reinvesting of such deposits or amounts paid
     or prepaid to the Lenders as a result of any of the following  events other
     than any  such  occurrence  as a  result  in the  change  of  circumstances
     described in Sections 5(a) and (b):

               (i) any payment,  prepayment  or  conversion of a LIBOR Loan on a
          date  other  than the  last day of its  Interest  Period  (whether  by
          acceleration, prepayment or otherwise);

               (ii) any failure to make a  principal  payment of a LIBOR Loan on
          the due date thereof; or

               (iii) any failure by  Borrowers  to borrow,  continue,  prepay or
          convert  to a LIBOR  Loan on the  dates  specified  in a notice  given
          pursuant to Section 2(c) or 4(c) hereof;  then Borrowers  shall pay to
          such Lender such amount as will  reimburse  such Lender for such loss,
          cost or expense. If any Lender makes such a claim for compensation, it
          shall  furnish to Borrowers  and Agent a statement  setting  forth the
          amount of such loss, cost or expense in reasonable  detail  (including
          an explanation of the basis for and the computation of such loss, cost
          or  expense)  and  the  amounts  shown  on  such  statement  shall  be
          conclusive and binding absent manifest error.

     6.  Collateral  Security.  To secure the  performance by Borrowers of their
obligations  hereunder,  and  under the  Notes,  Security  Instruments  and Rate
Management  Transactions,   whether  now  or  hereafter  incurred,   matured  or
unmatured,  direct  or  contingent,  joint or  several,  or joint

                                      -27-


and  several,  including  extensions,   modifications,  renewals  and  increases
thereof, and substitutions  therefor,  Borrowers shall herewith grant and assign
to Agent for the  ratable  benefit  of the  Lenders  a first  and prior  Lien on
certain of their Oil and Gas Properties,  certain related equipment, oil and gas
inventory,  as-extracted  collateral and proceeds of the foregoing.  The Oil and
Gas Properties  herewith mortgaged to the Agent by Borrowers shall represent not
less than 80% of the Engineered Value (as hereinafter defined) of Borrowers' Oil
and Gas  Properties as of the Effective  Date. In addition to the  mortgaging of
the Oil and Gas Properties,  PLP shall grant and assign to Agent for the ratable
benefit  of  Lenders a first and prior  Lien on the SSB  Account  and all assets
therein and on all shares of Energen Stock owned by PLP, PPC and Guarantor shall
grant and assign to Agent for the  ratable  benefit of Lenders a first and prior
Lien on all equity interests in PLP, PPC shall grant and assign to Agent for the
ratable  benefit of Lenders a first and prior  Lien on all equity  interests  in
Guarantor,  and Guarantor shall provide  Lenders with the Guaranty.  Obligations
arising from Rate Management  Transactions  between Borrowers and one or more of
the  Lenders  or an  Affiliate  of any of the  Lenders  shall be  secured by the
Collateral  on a pari  passu  basis with the  indebtedness  and  obligations  of
Borrowers  under  the  Loan  Documents.  All Oil and Gas  Properties  and  other
collateral in which Borrowers and Guarantor herewith grant or hereafter grant to
Agent for the  ratable  benefit  of the  Lenders a first and prior  Lien (to the
satisfaction of the Agent) in accordance with this Section 6, as such properties
and interests are from time to time  constituted,  are hereinafter  collectively
called the "Collateral".

     The  granting  and  assigning  of such  security  interests  and  Liens  by
Borrowers and Guarantor  shall be pursuant to Security  Instruments  in form and
substance reasonably  satisfactory to the Agent.  Concurrently with the delivery
of each of the  Security  Instruments  or within a reasonable  time  thereafter,
Borrowers  shall have  furnished to the Agent  mortgage  and title  opinions and
other title  information  reasonably  satisfactory  to Agent with respect to the
title  and Lien  status  of  Borrowers'  interests  in not less  than 80% of the
Engineered  Value of Borrowers'  mortgaged Oil and Gas  Properties.  "Engineered
Value"  for this  purpose  shall  mean  future net  revenues  discounted  at the
discount  rate being used by the Agent as of the date of any such  determination
utilizing the pricing parameters used in the engineering report furnished to the
Agent pursuant to Sections 7 and 12 hereof.  Borrowers will cause to be executed
and delivered to the Agent, in the future,  additional  Security  Instruments if
the  Agent  reasonably  deems  such  are  necessary  to  insure   perfection  or
maintenance of Lenders' security interests and Liens in not


                                      -28-



less than 80% of the Engineered Value of the Oil and Gas Properties or in any of
the other  Collateral.

     7. Borrowing Base.

          (a) Initial  Borrowing Base. At the Effective Date, the Borrowing Base
     shall be $50,000,000,  with the initial  Borrowing Base attributable to the
     Oil and Gas Properties  being  $43,000,000  and the initial  Borrowing Base
     attributable  to the Energen  Stock and cash proceeds from the sale thereof
     being $7,000,000.

          (b) Subsequent Determinations and Redeterminations of Borrowing Base.

               (i) Semi-Annual Determinations and Unscheduled  Redeterminations.
          Subsequent  determinations  of the Borrowing Base shall be made by the
          Lenders semi-annually on or about April 30 and October 31 of each year
          beginning  April 30,  2003,  or as  Unscheduled  Redeterminations.  In
          connection  with and as of,  each such  semi-annual  determination  or
          Unscheduled  Redetermination of the Borrowing Base, Lenders shall also
          redetermine the Monthly Commitment Reduction. Agent shall by notice to
          Borrower  no later than 45 days after its  receipt of the  engineering
          report required by Section 7(e) and all other information requested by
          Lenders (herein, together with the date of any similar notice by Agent
          pursuant to Section 7(b)(ii) below,  called a  "Determination  Date"),
          notify  Borrower of the  designation  by Lenders of the new  Borrowing
          Base and Monthly Commitment Reduction for the period beginning on such
          Determination  Date and continuing until, but not including,  the next
          Determination Date.

               (ii)  Monthly  Determinations.  In  addition  to the  semi-annual
          determinations and Unscheduled  Redeterminations of the Borrowing Base
          made in accordance  with Section  7(b)(i) above or 7(c) below, so long
          as the value of any Energen Stock is included in the  Borrowing  Base,
          subsequent  determinations of the Borrowing Base shall also be made by
          Agent  monthly  on or  about  the  last  day of each  month  beginning
          December 31, 2002. Such monthly  determinations shall be made by Agent
          utilizing the  Borrowing  Base value  attributable  to the Oil and Gas
          Properties as of the then most recent Determination Date and adding to
          it the  Borrowing  Base value of the Energen  Stock as  determined  by
          Agent pursuant to Section 7(e)(ii). Agent shall by notice to Borrowers
          within  fifteen

                                      -29-



          (15)  days  following  the  end of  the  month  for  which  a  monthly
          determination  is made by the Agent under this Section 7(b)(ii) notify
          Borrowers of the  designation  by Agent of the new Borrowing  Base for
          the period beginning on such  Determination Date and continuing until,
          but not including, the next Determination Date. The Monthly Commitment
          Reductions  will  not be  redetermined  by the  Agent  as  part of its
          monthly  determinations  of the  Borrowing  Base  under  this  Section
          7(b)(ii).  Notwithstanding  anything contained in this Agreement,  the
          Borrowing Base shall not include any value attributable to the Energen
          Stock or any proceeds from the sale thereof from and after January 31,
          2003.

               (c) Subsequent  Unscheduled  Redeterminations  of Borrowing Base.
          Within  thirty (30) days after either (i) receipt of notice from Agent
          that Lenders require an Unscheduled Redetermination, or (ii) Borrowers
          give  notice  to  Agent  of  their  desire  to  have  an   Unscheduled
          Redetermination  performed,  Borrowers  shall  furnish  to  Lenders an
          engineering  report  in  form  and  substance  satisfactory  to  Agent
          prepared  by  independent  petroleum  engineers  acceptable  to  Agent
          valuing  the Oil and Gas  Properties  utilizing  economic  and pricing
          parameters  used by the  Agent  as  established  from  time  to  time,
          together with such other information,  reports and data concerning the
          value of the Oil and Gas  Properties  as Agent  shall deem  reasonably
          necessary to determine the value of such Oil and Gas Properties. If an
          Unscheduled Redetermination is made by Lenders, the Agent shall notify
          Borrowers  within a  reasonable  time after  receipt of all  requested
          information  of  the  new  Borrowing   Base  and  Monthly   Commitment
          Reduction,   and  such  new  Borrowing  Base  and  Monthly  Commitment
          Reduction shall continue until the next Determination  Date.

               (d) Other  Determinations  of the Borrowing Base. If Borrowers do
          not  furnish  all  such  information,  reports  and  data by any  date
          specified in Section 7(c) or 7(e),  unless such failure is of no fault
          of Borrowers, Lenders may nonetheless designate the Borrowing Base and
          Monthly  Commitment  Reduction at any amounts  which  Lenders in their
          discretion  determine  and may  redesignate  the  Borrowing  Base  and
          Monthly  Commitment  Reduction  from  time  to time  thereafter  until
          Lenders  receive all such  information,  reports  and data,  whereupon
          Lenders shall  designate a new Borrowing  Base and Monthly  Commitment
          Reduction as described above.

                                      -30-



               (e) Evaluation Factors.

                    (i) Oil  and  Gas  Properties.  By  April  1 of  each  year,
               beginning April 1, 2003,  Borrowers  shall, at their own expense,
               furnish to Lenders an engineering report covering the Oil and Gas
               Properties  in form  and  substance  satisfactory  to  Agent  and
               prepared by an independent  petroleum engineering firm acceptable
               to Agent, said engineering report to utilize economic and pricing
               parameters  used by the Agent as  established  from time to time,
               together with such other information, reports and data concerning
               the  value  of the Oil and Gas  Properties  as Agent  shall  deem
               reasonably  necessary to determine  the value of such Oil and Gas
               Properties.  By October 1 of each year beginning October 1, 2003,
               Borrowers  shall,  at their own  expense,  furnish  to Lenders an
               engineering  report covering the Oil and Gas Properties,  in form
               and  substance  satisfactory  to Agent and prepared by Borrowers'
               in-house engineering staff, said engineering report to consist of
               an updated  reserve  report that takes into account major reserve
               and/or  value  changes that have  occurred  since the most recent
               engineering   report  prepared  by  the   independent   petroleum
               engineering firm as required above;  provided,  however,  that to
               the extent material Oil and Gas Properties are acquired after the
               date  of  the  most  recent  independent  engineering  report  as
               required  above,  Borrowers  shall  also,  at their own  expense,
               furnish  to  Lenders  on  or  before  October  1  an  independent
               engineering  report  meeting  the  requirements  set forth  above
               covering said newly acquired Oil and Gas Properties.  Each Lender
               shall determine the amount of the Borrowing Base  attributable to
               the Oil and Gas Properties and the Monthly  Commitment  Reduction
               based upon the loan  collateral  value  which such  Lender in its
               discretion  (using such  methodology,  assumptions  and  discount
               rates as such Lender  customarily  uses in  assigning  collateral
               value to oil and gas properties,  oil and gas gathering  systems,
               gas processing and plant operations)  assigns to such Oil and Gas
               Properties  at the time in  question  and based  upon such  other
               credit   factors   consistently   applied   (including,   without
               limitation,  the  assets,   liabilities,   cash  flow,  business,
               properties,  prospects, management and ownership of Borrowers and
               their  Affiliates)  as  such  Lender  customarily   considers  in
               evaluating similar oil and gas credits.

                    (ii) Energen Stock.  Agent shall determine the amount of the
               Borrowing  Base  attributable  to the Energen Stock by taking the
               sum of (A) the cash  included  in the SSB  Account  from sales of
               Energen Stock at the time of determination, plus (B) an amount

                                      -31-



               calculated by multiplying  (x) fifty percent (50%) (or such other
               percentage  as may be  determined  by  Majority  Lenders)  of the
               average  of the  daily  closing  sales  prices  per share for the
               Energen  Stock for the  fifteen  (15)  consecutive  trading  days
               immediately  preceding  the  last day of each  month,  by (y) the
               number of shares of Energen Stock pledged to Agent at the time of
               determination;   provided  however,   the  Borrowing  Base  value
               attributable to such cash proceeds and the Energen Stock by Agent
               shall  never  exceed  $7,000,000,  without  the  approval  of all
               Lenders.  The  closing  price  for  each  day  shall  be the last
               reported  sale price,  regular  way, or in case no such  reported
               sale takes place on such day,  the average of the closing bid and
               asked  prices,  regular  way, for such day, in either case on the
               New York Stock Exchange or other principal  exchange or quotation
               system on which the Energen  Stock is traded if the Energen Stock
               is not  listed  or  admitted  to  trading  on the New York  Stock
               Exchange.

                    (f) Required  Percentage of Lenders.  Except as specifically
               provided in Section 7(b)(ii),  the Borrowing Base  determinations
               pursuant to Section  7(b)(ii)  will be made by Agent  without the
               approval  of the  other  Lenders.  All  other  determinations  or
               Unscheduled  Redeterminations  of  the  Borrowing  Base  and  the
               Monthly Commitment Reduction require the approval of all Lenders.
               If the  Lenders  cannot  otherwise  agree on the  Borrowing  Base
               attributable  to the  Oil  and  Gas  Properties  or  the  Monthly
               Commitment Reduction,  each Lender shall submit in writing to the
               Agent its proposed Borrowing Base attributable to the Oil and Gas
               Properties  and Monthly  Commitment  Reduction  and the Borrowing
               Base  attributable  to the Oil and Gas Properties and the Monthly
               Commitment  Reduction  shall be set on the  basis  of the  lowest
               Borrowing Base attributable to the Oil and Gas Properties and the
               highest Monthly Commitment Reduction proposed by any Lender.

                    (g) Automatic  Reductions of Borrowing  Base. If at any time
               any of the Oil and Gas  Properties  are sold,  the Borrowing Base
               then in effect shall  automatically be reduced by an amount equal
               to the  amount of  prepayment  required  to be made  pursuant  to
               Section 12(r) hereof.  If at any time any of the Energen Stock is
               sold and the proceeds from such sale are received by or on behalf
               of a Borrower or the Guarantor or become available for withdrawal
               from the SSB  Account,  the  Borrowing  Base then in effect shall
               automatically be reduced by an amount equal to the Borrowing Base
               value  attributed  to such proceeds or to such Energen Stock sold
               as of the then most

                                      -32-




               recent   Determination   Date.   The  Borrowing   Base  shall  be
               additionally reduced from time to time pursuant to the provisions
               of Section 12(t) hereof and as elsewhere  provided herein.  It is
               expressly understood that Agent and Lenders have no obligation to
               designate the Borrowing Base or the Monthly Commitment  Reduction
               at any  particular  amounts,  except  in the  exercise  of  their
               discretion, whether in relation to the Commitment of otherwise.

     8. Fees.

          (a) Letter of Credit Fee.  Borrowers  shall pay to Agent the Letter of
     Credit fees required above in Section 2(e).

          (b) Borrowing Base Determination Fee. Borrowers shall pay to Agent for
     the  ratable  benefit  of Lenders  at the time  Agent  provides  any notice
     required by Section 7(b)(i) and 7(c), an amount equal to  three-eighths  of
     one percent  (.375%) of the amount of any  increase in the  Borrowing  Base
     upon a scheduled  semi-annual  determination  of the  Borrowing  Base or an
     Unscheduled  Redetermination.  The parties  acknowledge and agree that such
     fee is  intended  as  reasonable  compensation  to Lenders  for their time,
     effort and expense in determining the Borrowing Base.

          (c)  Unused  Commitment  Fee.  Borrowers  shall  pay to Agent  for the
     ratable  benefit  of the  Lenders  an unused  commitment  fee (the  "Unused
     Commitment  Fee") in an amount equal to  one-quarter  of one percent (.25%)
     times the daily average of the unadvanced  amount of the Commitment  (i.e.,
     the Commitment minus the Total  Outstandings).  Such Unused  Commitment Fee
     shall be  calculated  on the basis of a year  consisting  of 360 days.  The
     Unused Commitment Fee shall be payable quarterly in arrears on the last day
     of each calendar  quarter  beginning March 31, 2003, with the first payment
     being for the period from the Effective  Date through  March 31, 2003,  and
     with the final fee  payment  due on the  Maturity  Date for any period then
     ending for which the Unused  Commitment Fee shall not have been theretofore
     paid. In the event the  Commitment  terminates on any date prior to the end
     of any such  quarterly  period,  Borrowers  shall  pay to the Agent for the
     ratable benefit of the Lenders, on the date of such termination,  the total
     Unused Commitment Fee due for the period in which such termination  occurs.
     If a date for  payment of the Unused  Commitment  Fee shall be other than a
     Business Day such  payment  shall be made on the next  succeeding  Business
     Day.

     9.   Prepayments.

          (a) Voluntary  Prepayments.  Subject to the provisions of Section 5(e)
     hereof, Borrowers may at any time and from time to time, without penalty or
     premium,  prepay the Notes, in whole or in part. Each such prepayment shall
     be made on at least three (3) Business Days' notice to Agent in the case of
     LIBOR Loan  Tranches and without  notice in the case of Base Rate Loans and
     shall be in a minimum  amount of (i)  $500,000  or any  whole  multiple  of
     $100,000 in excess thereof (or the unpaid  balance of the Notes,  whichever
     is less), for Base Rate Loans, plus accrued interest  thereon,  to the date
     of  prepayment,  and (ii)  $1,000,000 or any whole  multiple of $100,000 in
     excess thereof (or the unpaid balance of the Notes,  whichever is less) for
     LIBOR Loans, plus accrued interest thereon to the date of prepayment.

          (b) Mandatory  Collateral or Prepayment For Borrowing Base Deficiency.
     In the event the Total  Outstandings  ever  exceed  the  Borrowing  Base as
     determined  by  Lenders  pursuant  to Section 7 hereof (a  "Borrowing  Base
     Deficiency"),  Borrowers  shall,  within  thirty  (30) days  after  written
     notification  from the  Agent,  or  within  ten  (10)  days  after  written
     notification  from  Agent  so long as  Energen  Stock  is held by  Agent as
     Collateral,   as   applicable,   either  (A)  by   instruments   reasonably
     satisfactory  in form and substance to the Lenders,  provide the Agent with
     collateral  with value and  quality in amounts  satisfactory  to all of the
     Lenders in their  discretion in order to increase the Borrowing  Base by an
     amount at least  equal to such  excess,  (B)  prepay,  without  premium  or
     penalty,  the principal  amount of the Notes in an amount at least equal to
     such excess plus accrued interest thereon to the date of prepayment, or (C)
     eliminate the Borrowing  Base  Deficiency  through a combination of (A) and
     (B) above. If the Total Outstandings ever exceed the Commitment as a result
     of a Monthly  Commitment  Reduction or any other required  reduction in the
     Commitment pursuant to Section 2(g) hereof,  then in such event,  Borrowers
     shall immediately  prepay the principal amount of the Notes in an amount at
     least equal to such excess plus accrued interest to the date of prepayment.

                                      -34-

     contract, agreement, law, regulation,  order, injunction,  judgment, decree
     or writ to which  Borrower  or  Guarantor  is  subject,  or  result  in the
     creation or imposition of any Lien or other  encumbrance upon any assets or

     of the Notes and the execution,  delivery and  performance by Borrowers and

     all tax returns  and  reports  required to be filed and has paid all taxes,
     assessments,  fees and other  governmental  charges  levied  upon it or its
     assets, properties or income which are due and payable,  including interest
     and penalties,  the failure of which to pay could reasonably be expected to

     faith by appropriate  proceedings  and for which adequate  reserves for the
     payment  thereof  as  required  by GAAP  has  been  provided  and  levy and
     execution thereon have been stayed and continue to be stayed.

          (j) Titles,  Etc. Each Borrower and Guarantor has good and  defensible

     limitation, the Oil and Gas Properties and other Collateral, free and clear
     of all Liens or other encumbrances except Permitted Liens.

          (k) Defaults.  Neither either Borrower nor Guarantor is in default and
     no event or circumstance has occurred which, but for the passage of time or
     the giving of notice, or both, would constitute a default under any loan or
     credit agreement, indenture, mortgage, deed of trust, security agreement or
     other  agreement or instrument  to which either  Borrower or Guarantor is a
     party in any respect that would be  reasonably  expected to have a Material
     Adverse Effect.  No Default or Event of Default  hereunder has occurred and
     is continuing.

          (l)  Casualties;  Taking of Properties.  Since the dates of the latest

     Oil and Gas Properties and other assets and properties in good and workable
     condition  at all  times  and make all  repairs,  replacements,  additions,
     betterments and improvements to the Oil and Gas Properties and other assets
     and properties as are needed and proper so that the business  carried on in
     connection  therewith  may be  conducted  properly and  efficiently  at all
     times;  (iii) take or cause to be taken  whatever  actions are necessary or
     desirable to prevent an event or condition of default by either Borrower or
     Guarantor under the provisions of any gas purchase or sales contract or any
     other  contract,  agreement  or lease  comprising a part of the Oil and Gas
     Properties  or other  collateral  security  hereunder  which  default could
     reasonably  be expected to result in a Material  Adverse  Effect;  and (iv)
     furnish Agent upon request evidence  reasonably  satisfactory to Agent that
     there are no Liens,  claims or  encumbrances on the Oil and Gas Properties,
     except Permitted Liens.

                                      -51-




          (o) Operation of Properties.  Except as provided in Subsections  12(p)
     and (q) below,  Borrowers will operate,  or use reasonable efforts to cause
     to be  operated,  all Oil and Gas  Properties  in a careful  and  efficient
     manner in accordance with the practice of the industry and in compliance in
     all material respects with all applicable laws, rules, and regulations, and
     in compliance in all material  respects with all  applicable  proration and
     conservation laws of the jurisdiction in which the properties are situated,
     and all applicable laws, rules, and regulations,  of every other agency and
     authority  from time to time  constituted to regulate the  development  and
     operation of the properties and the production and sale of hydrocarbons and
     other minerals therefrom;  provided, however, that Borrowers shall have the
     right  to   contest  in  good  faith  by   appropriate   proceedings,   the
     applicability or lawfulness of any such law, rule or regulation and pending
     such  contest may defer  compliance  therewith,  as long as such  deferment
     shall not subject the  properties  or any part  thereof to  foreclosure  or
     loss.

          (p) Compliance with Leases and Other  Instruments.  Borrowers will pay
     or cause to be paid and discharge all rentals,  delay  rentals,  royalties,
     production payment, and indebtedness required to be paid by either Borrower
     (or  required to keep  unimpaired  in all  material  respects the rights of
     either Borrower in the Oil and Gas Properties)  accruing under, and perform
     or cause to be  performed  in all  material  respects  each and every  act,
     matter,  or thing required of Borrowers by each and all of the assignments,
     deeds, leases, subleases,  contracts, and agreements in any way relating to
     Borrowers  or any of the Oil and Gas  Properties  and do all  other  things
     necessary  of  Borrowers to keep  unimpaired  in all material  respects the
     rights of Borrowers  thereunder  and to prevent the  forfeiture  thereof or
     default thereunder; provided, however, that nothing in this Agreement shall
     be deemed to require either Borrower to perpetuate or renew any oil and gas
     lease  or  other  lease  by  payment  of  rental  or  delay  rental  or  by
     commencement  or  continuation of operations nor to prevent either Borrower
     from  abandoning  or releasing any oil and gas lease or other lease or well
     thereon when, in any of such events, in the opinion of Borrowers  exercised
     in good faith,  it is not in the best  interest of Borrowers to  perpetuate
     the same.

          (q) Certain Additional Assurances Regarding Maintenance and Operations
     of Properties. With respect to those Oil and Gas

                                      -52-



     Properties  which are being operated by operators other than the Borrowers,
     Borrowers shall not be obligated to perform any  undertakings  contemplated
     by the  covenants  and agreement  contained in  Subsections  12(n) or 12(o)
     hereof  which are  performable  only by such  operators  and are beyond the
     control  of  Borrowers;  however,  Borrowers  agree  to  promptly  take all
     reasonable actions available under any operating agreements or otherwise to
     bring about the performance of any such material  undertakings  required to
     be performed thereunder.

          (r) Sale of Certain  Assets/Prepayment  of  Proceeds.  Borrowers  will
     immediately pay over to the Agent for the ratable benefit of the Lenders as
     a prepayment of principal on the Notes and a reduction of the  Commitments,
     an amount  equal to 100% of the net  proceeds  received by either  Borrower
     from the sale of the Oil and Gas  Properties,  which sale has been approved
     in advance by the Lenders.  Borrowers and/or Guarantor will immediately pay
     over to the Agent for the ratable benefit of the Lenders as a prepayment of
     principal on the Notes and a reduction of the Commitments,  an amount equal
     to 100% of the net  proceeds  received  by any of them from the sale of any
     Energen  Stock.  Any such  prepayment of principal on the Notes required by
     this Section  12(r),  shall not be in lieu of, but shall be in addition to,
     any Monthly  Commitment  Reduction  or  mandatory  prepayment  of principal
     required to be paid pursuant to Section 9(b) hereof.

          (s) Title  Matters.  Within sixty (60) days after the  Effective  Date
     with respect to the Oil and Gas  Properties  listed on Schedule "6" hereto,
     Borrowers shall furnish Agent with title opinions and/or title  information
     reasonably  satisfactory  to Agent  showing  good and  defensible  title of
     Borrowers  to such Oil and Gas  Properties  subject  only to the  Permitted
     Liens.  As to any Oil and Gas  Properties  hereafter  mortgaged  to  Agent,
     Borrowers  will  promptly  (but in no  event  more  than  sixty  (60)  days
     following  such  mortgaging),  furnish,  if  requested,  Agent  with  title
     opinions and/or title information reasonably  satisfactory to Agent showing
     good and  defensible  title  of  Borrowers  to such Oil and Gas  Properties
     subject only to Permitted Liens.

          (t) Curative Matters.  Within sixty (60) days after the Effective Date
     with  respect to matters  listed on Schedule  "7" and,  thereafter,  within
     sixty (60) days after  receipt by  Borrowers  from Agent or its  counsel of
     written notice of title defects the Agent

                                      -53-




     reasonably  requires to be cured,  Borrowers  shall either (i) provide such
     curative information,  in form and substance satisfactory to Agent, or (ii)
     substitute Oil and Gas Properties of value and quality  satisfactory to the
     Agent for all of Oil and Gas  Properties  for which such title curative was
     requested  but upon  which  Borrowers  elected  not to  provide  such title
     curative  information,  and,  within sixty (60) days of such  substitution,
     provide  title  opinions  or title  information  satisfactory  to the Agent
     covering the Oil and Gas Properties so  substituted.  If the Borrowers fail
     to satisfy (i) or (ii) above within the time specified, the loan collateral
     value  assigned by the Lenders to the Oil and Gas Properties for which such
     curative  information  was  requested  shall be deducted from the Borrowing
     Base resulting in a reduction thereof.

          (u) Change of Principal Place of Business. Each Borrower and Guarantor
     shall give Agent at least  thirty  (30) days  prior  written  notice of its
     intention  to move its  principal  place of  business  from the address set
     forth in Section 17 hereof.

          (v)  Additional  Collateral.  Borrowers  agree  to  regularly  monitor
     engineering  data  covering  all  producing  oil  and  gas  properties  and
     interests  owned or acquired by either Borrower on or after the date hereof
     and to mortgage or cause to be mortgaged  such of the same to Agent for the
     ratable  benefit of the Lenders in  substantially  the form of the Security
     Instruments,  as  applicable,  to the extent that the Lenders  shall at all
     times during the existence of the Commitment be secured by perfected  Liens
     and security  interests  covering not less than eighty percent (80%) of the
     Engineered  Value of all producing Oil and Gas Properties of Borrowers.  In
     addition,  the Borrowers  agree that in connection  with the  mortgaging of
     such additional oil and gas properties, they shall within a reasonable time
     thereafter, deliver or cause to be delivered to the Agent such mortgage and
     title  opinions and other title  information  with respect to the title and
     Lien status of such oil and gas  properties as may be necessary to maintain
     at all times a level of such title  opinions and title  information  of not
     less than eighty percent (80%) of the  Engineered  Value of all Oil and Gas
     Properties mortgaged to the Agent for the ratable benefit of the Lenders.

          (w) Crude Oil Hedging.  Commencing on April 1, 2003,  Borrowers  shall
     maintain with counterparties  acceptable to the Agent non-speculative crude
     oil price hedges for rolling  twenty-four  (24) month  periods,  but not to
     extend beyond the Maturity Date

                                      -54-



     unless Borrowers  otherwise elect, and with prices and other terms as shall
     be approved in advance by Agent covering (i) at least seventy-five  percent
     (75%) of Borrowers'  estimated monthly crude oil production from Borrowers'
     proved producing Oil and Gas Properties for the nine months ending December
     31, 2003, (ii) at least sixty percent (60%) of Borrowers' estimated monthly
     crude  oil  production  from  Borrowers'   proved  producing  Oil  and  Gas
     Properties  during the 2004 calendar year, and (iii) at least fifty percent
     (50%) of Borrowers'  estimated monthly crude oil production from Borrowers'
     proved  producing Oil and Gas Properties  during the 2005 calendar year and
     thereafter until the Maturity Date.

     13. Negative Covenants.  A deviation from the provisions of this Section 13
shall not  constitute an Event of Default under this Agreement if such deviation
is consented to in writing by Majority  Lenders  prior to the date of deviation.
Each Borrower and Guarantor,  as  applicable,  will at all times comply with the
covenants  contained  in this Section 13 from the date hereof and for so long as
the Commitment is in existence or any amount is owed to the Agent or the Lenders
under this Agreement or the other Loan Documents.

          interest  or other  encumbrance  on any of its  respective  assets  or
          properties except Permitted Liens; or

               (ii) sell, lease, transfer or otherwise dispose of, in any fiscal
          year, any of its  respective  assets except for (A) sales of extracted
          petroleum   hydrocarbons   made  in  the  ordinary  course  of  either
          Borrower's  oil and gas  business,  (B) to the  extent  not  otherwise
          forbidden under the Security Instruments,  equipment that is worthless
          or obsolete or which is replaced by equipment of equal  suitability in
          value, and interests in oil and gas leases,  or portions  thereof,  so
          long as no well  situated  on any such  lease or  located  on any unit
          containing all or any part thereof, is capable (or is subject to being
          made capable through  commercially  feasible operations) of production
          oil, gas or other  hydrocarbons or minerals in commercial  quantities,
          and (C) sales of the Energen  Stock,  provided that such stock is sold
          at its fair  market  value  and in  compliance  with any  restrictions
          thereon,  and that the net  proceeds

                                      -55-

          (d)  Adjusted  Consolidated  Net Worth.  At all times  during the term
     hereof,  PPC's Adjusted  Consolidated  Net Worth shall not be less than (a)
     $40,000,000,  plus (b) seventy-five  percent (75%) of the net proceeds from
     any  equity  securities  issued  by the PPC on or  after  the  date of this
     Agreement,  plus (c) fifty percent (50%) of PPC's  Consolidated  Net Income
     for each fiscal  quarter,  if positive,  and zero percent (0%) if negative,
     determined on a cumulative  basis,  for the period  beginning July 1, 2002,
     and ending on the last day of the most recent fiscal quarter as of the time
     in question.  For purposes of calculating  PPC's Adjusted  Consolidated Net
     Worth in connection  with this Section 13(d),  there shall be excluded from
     Consolidated Net Income (to the extent otherwise included therein as may be
     required  by  GAAP)  the  cumulative  effect  of  a  change  in  accounting

     such  consolidation  or merger and if,  after  giving  effect  thereto,  no
     Default or Event of Default shall have occurred and be continuing.

          (f) Debts,  Guaranties and Other Obligations.  Neither either Borrower
     nor Guarantor  will, and will not permit any Subsidiary to, incur,  create,
     assume or in any manner become or be liable in respect of any indebtedness,
     or guarantee  or otherwise in any manner  become or be liable in respect of

          yet due or are being  contested  in good faith by  appropriate  action
          promptly initiated and diligently conducted,  if such reserve as shall
          be  required  by GAAP  shall  have  been  made  therefor  and levy and
          execution thereon have been stayed and continue to be stayed; or

               (iii)  indebtedness  (other  than  in  connection  with a loan or

     payment of such  dividends  would not cause a Default or Event of  Default,
     (ii) either Borrower's  Subsidiaries may declare,  pay or make dividends or
     distributions  to such Borrower,  and (iii) PLP may make  distributions  to
     Guarantor,   provided  that  Guarantor   immediately   redistributes   such
     distributions to PPC.

          (h) Loans and Advances.  Neither either  Borrower nor Guarantor  will,

     14.  Events of Default.  Any one or more of the  following  events shall be
considered an "Event of Default" as that term is used herein:

          (a) Borrowers shall fail to pay when due or declared due the principal
     of, and the interest on, the Notes or any fee or any other  indebtedness of
     Borrowers  incurred  pursuant  to this  Agreement  or any of the other Loan
     Documents; or

          (b)  Any  representation  or  warranty  made  by  either  Borrower  or
     Guarantor  under  this  Agreement,  or  in  any  certificate  or  statement
     furnished  or  made  to  the  Lenders  pursuant  hereto,  or in  connection
     herewith,  or in connection with any document  furnished  hereunder,  shall
     prove to be untrue in any  material  respect  as of the date on which  such
     representation or warranty is made (or deemed made), or any representation,
     statement (including Financial  Statements),  certificate,  report or other
     data  furnished or to be furnished or made by either  Borrower or Guarantor
     under any Loan  Document,  including  this  Agreement,  proves to have been
     untrue  in any  material  respect,  as of the  date as of which  the  facts
     therein set forth were stated or certified; or

          (c) Default shall be made in the due  observance or performance of any
     of the covenants or agreements of either Borrower or Guarantor contained in
     the Loan Documents, including this Agreement (excluding covenants contained
     in Section 13 of the Agreement for which there is no cure period), and such
     default shall  continue for more than thirty (30) days after written notice
     from Agent is received by Borrowers; or

          (d) Default shall be made in the due  observance or performance of the

     money other than the Notes,  for which  either  Borrower,  Guarantor or any
     Subsidiary is liable (directly, by assumption,  as guarantor or otherwise),
     or any  obligations  secured by any  mortgage,  pledge or other  consensual
     security interest with respect thereto,  on any asset or property of either
     Borrower,  Guarantor  or any  Subsidiary  or in  respect  of any  agreement
     relating  to any such  obligations,  unless  the  aggregate  amount of such
     obligations  in respect of which such default  shall have  occurred is less
     than $250,000; or

                                      -61-




          (f) Either  Borrower,  Guarantor or any  Subsidiary  shall  commence a
     voluntary case or other proceeding seeking  liquidation,  reorganization or
     other  relief  with  respect to itself or its debts  under any  bankruptcy,
     insolvency  or other  similar law now or  hereafter in effect or seeking an
     appointment of a trustee, receiver, liquidator,  custodian or other similar
     official of it or any substantial part of its property, or shall consent to
     any such relief or to the  appointment of or taking  possession by any such
     official in an involuntary case or other proceeding  commenced  against it,
     or shall make a general  assignment for the benefit of creditors,  or shall
     fail  generally  to pay its debts as they  become  due,  or shall  take any
     corporate action authorizing the foregoing; or

          (g) An  involuntary  case or  other  proceeding,  shall  be  commenced
     against either Borrower,  Guarantor or any Subsidiary seeking  liquidation,
     reorganization  or other  relief with  respect to it or its debts under any
     bankruptcy, insolvency or similar law now or hereafter in effect or seeking
     the  appointment  of a trustee,  receiver,  liquidator,  custodian or other
     similar  official of it or any substantial  part of its property,  and such
     involuntary case or other proceeding shall remain  undismissed and unstayed
     for a period of thirty (30) days;  or an order for relief  shall be entered
     against  either  Borrower,  Guarantor or any  Subsidiary  under the federal
     bankruptcy laws as now or hereinafter in effect; or

          (h) A final  judgment  or order for the  payment of money in excess of
     $250,000 (or judgments or orders  aggregating in excess of $250,000)  shall
     be rendered against either  Borrower,  Guarantor or any Subsidiary and such
     judgments or orders shall continue unsatisfied and unstayed for a period of
     thirty (30) days; or

          (i) In the event the Total  Outstandings  shall at any time exceed the
     Borrowing  Base  established  for the Notes,  and  Borrowers  shall fail to
     comply with the provisions of Section 9(b) hereof; or

          (j) An event of default  (as  defined  therein)  shall occur under any
     agreement entered into in connection with any Rate Management  Transaction;
     or

          (k) A Change of Management shall occur; or

                                      -62-




          (l) Any Lien for failure to pay income, payroll, FICA or similar taxes
     shall be  filed by the U. S.  Government  or any  agent or  instrumentality
     thereof against either  Borrower,  Guarantor or any  Subsidiary,  or any of
     their respective assets; or

          (m) Any of the Loan Documents  shall cease,  for any reason,  to be in
     full force and effect, or either Borrower or Guarantor shall so assert.

     Upon occurrence of any Event of Default  specified in Subsections 14(f) and
(g) hereof,  the entire  principal  amount due under the Notes and all  interest
then accrued thereon,  and any other liabilities of Borrowers  hereunder,  shall
become  automatically  and  immediately  due and payable all without  notice and
without presentment, demand, protest, notice of protest or dishonor or any other
notice of default of any kind, all of which are hereby  expressly  waived by the
Borrowers and Guarantor.  Upon the occurrence of any other Event of Default, the
Agent,  upon  request  of  Majority  Lenders,  shall by  written  notice  to the
Borrowers  declare the principal of, and all interest then accrued on, the Notes
and any other liabilities  hereunder to be forthwith due and payable,  whereupon
the same shall  forthwith  become due and payable without  presentment,  demand,
protest, notice of intent to accelerate,  notice of acceleration or other notice
of any kind, all of which the Borrowers and Guarantor  hereby  expressly  waive,
anything contained herein or in the Notes to the contrary notwithstanding.

     Upon the occurrence and during the continuance of any Event of Default, the
Lenders are hereby authorized at any time and from time to time,  without notice
to the Borrowers or the Guarantor (any such notice being expressly waived by the
Borrowers and the Guarantor), to set-off and apply any and all deposits (general
or  special,  time or demand,  provisional  or final) at any time held and other
indebtedness at any time owing by any of the Lenders to or for the credit or the
account of either Borrower or Guarantor  against any and all of the indebtedness
of the  Borrowers  under  the  Notes  and the  Loan  Documents,  including  this
Agreement, irrespective of whether or not the Lenders shall have made any demand
under the Loan  Documents,  including  this  Agreement or the Notes and although
such  indebtedness  may be unmatured.  Any amount  set-off by any of the Lenders
shall be applied  against the  indebtedness  owed the  Lenders by the  Borrowers
pursuant to this  Agreement and the Notes.  The Lenders agree promptly to notify
the Borrowers after any such setoff and  application,  provided that the failure
to  give  such  notice  shall  not  affect  the  validity  of such

                                      -63-



set-off  and  application.  The rights of the Lender  under this  Section are in
addition to other  rights and remedies  (including,  without  limitation,  other
rights of set-off) which the Lenders may have.

     15. The Agent and the Lenders.

          (a) Appointment and  Authorization.  Each Lender hereby appoints Agent
     as its  nominee  and agent,  in its name and on its  behalf:  (i) to act as
     nominee for and on behalf of such  Lender in and under all Loan  Documents;
     (ii) to  arrange  the means  whereby  the funds of  Lenders  are to be made
     available to the  Borrowers  under the Loan  Documents;  (iii) to take such
     action as may be  requested by any Lender  under the Loan  Documents  (when
     such  Lender is entitled to make such  request  under the Loan  Documents);
     (iv) to receive all  documents  and items to be furnished to Lenders  under
     the Loan Documents;  (v) to be the secured party,  mortgagee,  beneficiary,
     and similar  party in respect  of, and to receive,  as the case may be, any
     collateral for the benefit of Lenders;  (vi) to promptly distribute to each
     Lender all material  information,  requests,  documents and items  received
     from the Borrowers or Guarantor under the Loan Documents; (vii) to promptly
     distribute  to each Lender such  Lender's  Pro Rata Part of each payment or
     prepayment  (whether  voluntary,  as  proceeds  of  insurance  thereon,  or
     otherwise) in accordance with the terms of the Loan Documents and (viii) to
     deliver  to  the  appropriate  Persons  requests,  demands,  approvals  and
     consents received from Lenders. Each Lender hereby authorizes Agent to take
     all actions and to exercise  such powers  under the Loan  Documents  as are
     specifically  delegated to Agent by the terms  hereof or thereof,  together
     with all other powers reasonably  incidental  thereto.  With respect to its
     Commitment  hereunder  and the Notes issued to it, Agent and any  successor
     Agent  shall have the same  rights  under the Loan  Documents  as any other
     Lender and may exercise  the same as though it were not the Agent;  and the
     term "Lender" or "Lenders"  shall,  unless otherwise  expressly  indicated,
     include  Agent and any successor  Agent in its capacity as a Lender.  Agent
     and any successor  Agent and its Affiliates may accept  deposits from, lend
     money to, act as trustee under  indentures  of and generally  engage in any
     kind of business with the Borrowers or Guarantor,  and any Person which may
     do  business  with the  Borrowers  or  Guarantor,  all as if Agent  and any
     successor  Agent was not Agent  hereunder  and  without any duty to account
     therefor to the Lenders;  provided  that, if any payments in respect of any
     property (or the proceeds  thereof) now or hereafter in

                                      -64-



     the possession or control of Agent which may be or become  security for the
     obligations of the Borrowers or Guarantor  arising under the Loan Documents
     by reason of the general description of indebtedness secured or of property
     contained in any other agreements,  documents or instruments related to any
     such other business shall be applied to reduction of the obligations of the
     Borrowers and Guarantor arising under the Loan Documents,  then each Lender
     shall be entitled to share in such  application  according  to its Pro Rata
     Part thereof. Each Lender, upon request of any other Lender, shall disclose
     to  all  other  Lenders  all  indebtedness  and  liabilities,   direct  and
     contingent, of the Borrowers and Guarantor to such Lender as of the time of
     such request.

          (b) Note Holders. From time to time as other Lenders become a party to
     this  Agreement,  Agent shall obtain  execution by Borrowers of  additional
     Notes in amounts  representing the Commitments of each such new Lender,  up
     to an aggregate  face amount of all Notes not exceeding  $100,000,000.  The
     obligation  of such  Lender  shall be governed  by the  provisions  of this
     Agreement,  including  but not limited  to, the  obligations  specified  in
     Section 2 hereof.  From time to time,  Agent may  require  that the Lenders
     exchange  their  Notes  for  newly  issued  Notes  to  better  reflect  the
     Commitments  of the  Lenders.  Agent may treat the payee of any Note as the
     holder  thereof  until  written  notice of transfer has been filed with it,
     signed by such payee and in form satisfactory to Agent.

          (c)  Consultation  with Counsel.  Lenders agree that Agent may consult
     with legal counsel selected by Agent and shall not be liable for any action
     taken or suffered in good faith by it in accordance with the advice of such
     counsel.  LENDERS  ACKNOWLEDGE  THAT  COTTON,  BLEDSOE,  TIGHE & DAWSON  IS
     COUNSEL FOR FIRST  AMERICAN,  BOTH AS AGENT AND AS A LENDER,  AND THAT SUCH
     FIRM DOES NOT REPRESENT  ANY OF THE OTHER  LENDERS IN CONNECTION  WITH THIS
     TRANSACTION.

          (d) Documents. Agent shall not be under a duty to examine or pass upon
     the validity, effectiveness, enforceability, genuineness or value of any of
     the Loan Documents or any other instrument or document  furnished  pursuant
     thereto or in connection  therewith,  and Agent shall be entitled to assume
     that the same are valid,  effective,  enforceable and genuine and what they
     purport to be.

                                      -65-




          (e)  Resignation or Removal of Agent.  Subject to the  appointment and
     acceptance of a successor Agent as provided below,  Agent may resign at any
     time by giving written  notice thereof to Lenders and Borrowers,  and Agent
     may be removed at any time with or without cause by all Lenders  (excluding
     the Agent). If no successor Agent has been so appointed by Majority Lenders
     (and approved by the  Borrowers) and has accepted such  appointment  within
     thirty (30) days after the retiring Agent's giving of notice of resignation
     or removal of the retiring Agent, then the retiring Agent may, on behalf of
     Lenders, appoint a successor Agent. Any successor Agent must be approved by
     Borrowers,  which  approval  will not be  unreasonably  withheld.  Upon the
     acceptance of any appointment as Agent hereunder by a successor Agent, such
     successor Agent shall  thereupon  succeed to and become vested with all the
     rights and duties of the retiring  Agent,  and the retiring  Agent,  as the
     case may be, shall be discharged from its duties and obligations hereunder.
     After any retiring Agent's  resignation or removal  hereunder as Agent, the
     provisions  of this Section 15 shall  continue in effect for its benefit in
     respect  to any  actions  taken or  omitted  to be taken by it while it was
     acting as Agent. To be eligible to be an Agent hereunder the party serving,
     or to serve,  in such capacity must own a Pro Rata Part of the  Commitments
     equal to the level of Commitment required to be held by any Lender pursuant
     to Section 29 hereof.

          (f)  Responsibility  of Agent.  It is expressly  understood and agreed
     that the  obligations  of Agent  under the Loan  Documents  are only  those
     expressly set forth in the Loan  Documents and that Agent shall be entitled
     to  assume  that no  Default  or  Event  of  Default  has  occurred  and is
     continuing,  unless Agent has actual knowledge of such fact or has received
     notice from a Lender or the  Borrowers  that such  Lender or the  Borrowers
     consider  that a  Default  or an  Event  of  Default  has  occurred  and is
     continuing and specifying the nature thereof.  Neither Agent nor any of its
     directors,  officers, attorneys or employees shall be liable for any action
     taken or omitted to be taken by them under or in  connection  with the Loan
     Documents,  except  for  its or  their  own  gross  negligence  or  willful
     misconduct.  Agent shall not incur  liability under or in respect of any of
     the Loan  Documents  by  acting  upon  any  notice,  consent,  certificate,
     warranty  or other  paper or  instrument  believed  by it to be  genuine or
     authentic or to be signed by the proper  party or parties,  or with respect
     to  anything  which  it may do or  refrain  from  doing  in the  reasonable
     exercise  of its  judgment,  or  which  may seem to it to be

                                      -66-



     necessary   or   desirable.   The   Syndication   Agent   shall   have   no
     responsibilities as an agent hereunder.

          Agent shall not be responsible to Lenders for any of the Borrowers' or
     Guarantor's recitals,  statements,  representations or warranties contained
     in any of the Loan  Documents,  or in any  certificate  or  other  document
     referred to or provided for in, or received by any Lender  under,  the Loan
     Documents,  or  for  the  value,  validity,   effectiveness,   genuineness,
     enforceability  or  sufficiency  of any of the  Loan  Documents  or for any
     failure by the  Borrowers or Guarantor to perform any of their  obligations
     hereunder or thereunder.  Agent may employ agents and attorneys-in-fact and
     shall not be answerable, except as to money or securities received by it or
     its authorized  agents, for the negligence or misconduct of any such agents
     or attorneys-in-fact selected by it with reasonable care.

          The  relationship  between Agent and each Lender is only that of agent
     and principal and has no fiduciary  aspects.  Nothing in the Loan Documents
     or  elsewhere  shall  be  construed  to  impose  on  Agent  any  duties  or
     responsibilities  other than those for which  express  provision is therein
     made. In  performing  its duties and  functions  hereunder,  Agent does not
     assume  and  shall  not be deemed to have  assumed,  and  hereby  expressly
     disclaims,  any obligation or responsibility  toward or any relationship of
     agency or trust with or for the Borrowers or any of their  beneficiaries or
     other creditors.  As to any matters not expressly  provided for by the Loan
     Documents,  Agent shall not be required to exercise any  discretion or take
     any action,  but shall be  required  to act or to refrain  from acting (and
     shall be fully  protected in so acting or refraining  from acting) upon the
     instructions of all Lenders and such instructions shall be binding upon all
     Lenders and all holders of the Notes;  provided,  however, that Agent shall
     not be required to take any action which is contrary to the Loan  Documents
     or applicable law.

          Agent  shall have the right to exercise  or refrain  from  exercising,
     without notice or liability to the Lenders,  any and all rights afforded to
     Agent by the Loan  Documents  or which  Agent  may have as a matter of law;
     provided,  however,  Agent shall not (i) except as  provided  herein and in
     Section 7(b)(ii) hereof,  without the consent of all Lenders  designate the
     amount of the Borrowing  Base or the Monthly  Commitment  Reduction or (ii)
     without the consent of Majority Lenders,  take any other action with regard
     to  amending  the

                                      -67-



     Loan Documents, waiving any default under the Loan Documents,  releasing or
     substituting  any Collateral  (except as permitted in Section 15(q) hereof)
     or taking any other  action with  respect to the Loan  Documents.  Provided
     further,  however,  that no  amendment,  waiver,  or other  action shall be
     effected  pursuant to the preceding  clause (ii) without the consent of all
     Lenders  which:  (a) would  increase  the  Borrowing  Base or decrease  the
     Monthly Commitment Reduction,  (b) would reduce any fees hereunder,  or the
     principal  of, or the interest on, any  Lender's  Note or Notes,  (c) would
     postpone  any date  fixed for any  payment  of any fees  hereunder,  or any
     principal or interest of any Lender's Note or Notes, (d) would increase the
     aggregate  Commitments or any Lender's individual  Commitment  hereunder or
     would materially  alter Agent's  obligations to any Lender  hereunder,  (e)
     would release  Borrowers from their  obligation to pay any Lender's Note or
     Notes,  (f) would  change the  definition  of Majority  Lenders,  (g) would
     extend the Maturity  Date or (h) would amend this  sentence or the previous
     sentence. Agent shall not have liability to Lenders for failure or delay in
     exercising  any  right or power  possessed  by Agent  pursuant  to the Loan
     Documents or otherwise  unless such failure or delay is caused by the gross
     negligence of the Agent, in which case only the Agent  responsible for such
     gross negligence shall have liability therefor to the Lenders.

          (g) Independent Investigation. Each Lender expressly acknowledges that
     neither the Agent nor any of its officers,  directors,  employees,  agents,
     attorneys in fact or Affiliates has made any  representations or warranties
     to it and that no act by the Agent hereinafter taken,  including any review
     of the  affairs  of  the  Borrowers  and  Guarantor,  shall  be  deemed  to
     constitute any representation or warranty by the Agent to any Lender.  Each
     Lender severally  represents and warrants to Agent that it has made its own
     independent  investigation  and  assessment of the financial  condition and
     affairs of the Borrowers  and  Guarantor in connection  with the making and
     continuation of its participation  hereunder and has not relied exclusively
     on any information provided to such Lender by Agent in connection herewith,
     and each Lender represents,  warrants and undertakes to Agent that it shall
     continue to make its own independent  appraisal of the credit worthiness of
     the  Borrowers  and  Guarantor  while  the  Notes  are  outstanding  or its
     Commitments  hereunder  are in force.  Agent  shall not be required to keep
     itself  informed as to the  performance  or observance by the Borrowers and
     Guarantor of this Agreement or any other  document

                                      -68-



     referred to or provided for herein or to inspect the properties or books of
     the  Borrowers  and  Guarantor.  Other than as provided in this  Agreement,
     Agent shall not have any duty,  responsibility  or liability to provide any
     Lender  with  any  credit  or other  information  concerning  the  affairs,
     financial  condition or business of the Borrowers  and Guarantor  which may
     come into the possession of Agent.

          (h)  Indemnification.   Lenders  agree  to  indemnify  Agent  and  the
     Syndication  Agent  ("Indemnified   Agents")  ratably  according  to  their
     respective  Commitments  on a Pro Rata basis,  from and against any and all
     liabilities,  obligations,  losses, damages, penalties, actions, judgments,
     suits,  costs,  expenses or disbursements of any proper and reasonable kind
     or nature  whatsoever  which may be imposed  on,  incurred  by or  asserted
     against any Indemnified  Agent in any way relating to or arising out of the
     Loan  Documents  or any action  taken or omitted by any  Indemnified  Agent
     under the Loan  Documents,  provided that no Lender shall be liable for any
     portion  of such  liabilities,  obligations,  losses,  damages,  penalties,
     actions,  judgments, suits, costs, expenses or disbursements resulting from
     any Indemnified Agent's gross negligence or willful misconduct. Each Lender
     shall be entitled to be  reimbursed by any such  Indemnified  Agent for any
     amount such Lender paid to any such  Indemnified  Agent under this  Section
     15(h) to the extent such  Indemnified  Agent has been  reimbursed  for such
     payments by  Borrowers  or any other  Person.  THE  PARTIES  INTEND FOR THE
     PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT THE  INDEMNIFIED  AGENTS
     FROM THE CONSEQUENCES OF ANY LIABILITY, INCLUDING STRICT LIABILITY, IMPOSED
     OR  THREATENED  TO BE IMPOSED ON ANY  INDEMNFIED  AGENT AS WELL AS FROM THE
     CONSEQUENCES OF ITS OWN  NEGLIGENCE,  WHETHER OR NOT THAT NEGLIGENCE IS THE
     SOLE, CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY.

          (i) Benefit of Section 15. The agreements contained in this Section 15
     are solely for the benefit of Agent,  Syndication Agent and the Lenders and
     are not for the  benefit  of, or to be relied  upon by, the  Borrower,  any
     Affiliate of the Borrowers or any other Person.

          (j) Pro Rata  Treatment.  Subject to the provisions of this Agreement,
     each  payment  (including  each  prepayment)  by  the  Borrowers  and  each
     collection by Lenders (including offsets) on

                                      -69-



     account of the principal of and interest on the Notes and fees provided for
     in this  Agreement,  that are payable by the  Borrowers,  shall be made Pro
     Rata; provided, however, in the event that any Defaulting Lender shall have
     failed to make an Advance as contemplated  under Section 3 hereof and Agent
     or another Lender or Lenders shall have made such Advance, payment received
     by Agent for the account of such Defaulting  Lender or Lenders shall not be
     distributed  to such  Defaulting  Lender or Lenders  until such  Advance or
     Advances shall have been repaid in full to the Lender or Lenders who funded
     such Advance or Advances.

          (k) Assumption as to Payments. Except as specifically provided herein,
     unless Agent shall have  received  notice from the  Borrowers  prior to the
     date on which any payment is due to Lenders  hereunder  that the  Borrowers
     will not make such  payment in full,  Agent may,  but shall not be required
     to,  assume that the  Borrowers  have made such payment in full to Agent on
     such date and Agent may,  in  reliance  upon such  assumption,  cause to be
     distributed  to each Lender on such due date an amount  equal to the amount
     then due such  Lender.  If and to the extent the  Borrowers  shall not have
     made  such  payment  in full to Agent,  each  Lender  shall  repay to Agent
     forthwith on demand such amount  distributed  to such Lender  together with
     interest thereon,  for each day from the date such amount is distributed to
     such Lender until the date such Lender repays such amount to Agent,  at the
     interest rate applicable to such portion of the Loan.

          (l) Other Financings.  Without limiting the rights to which any Lender
     otherwise is or may become entitled, such Lender shall have no interest, by
     virtue of this  Agreement  or the Loan  Documents,  in (a) any  present  or
     future  loans  from,  letters  of credit  issued  by, or  leasing  or other
     financial  transactions  by,  any other  Lender  to, on behalf  of, or with
     either  Borrowers or Guarantor  (collectively  referred to herein as "Other
     Financings")  other  than the  obligations  hereunder;  (b) any  present or
     future  guarantees  by or for the account of either  Borrower or  Guarantor
     which are not contemplated by the Loan Documents; (c) any present or future
     property  taken as  security  for any  such  Other  Financings;  or (d) any
     property now or hereafter in the  possession or control of any other Lender
     which may be or become  security for the  obligations of either Borrower or
     Guarantor  arising  under  any  loan  document  by  reason

                                      -70-



     of the general description of indebtedness secured or property contained in
     any other agreements,  documents or instruments  relating to any such Other
     Financings.

          (m) Interests of Lenders. Nothing in this Agreement shall be construed
     to create a partnership or joint venture  between  Lenders for any purpose.
     Agent,  Lenders,  Borrowers and  Guarantor  recognize  that the  respective
     obligations of Lenders under the Commitments shall be several and not joint
     and that neither Agent nor any of Lenders shall be responsible or liable to
     perform  any of the  obligations  of the other under this  Agreement.  Each
     Lender is deemed to be the  owner of an  undivided  interest  in and to all
     rights,  titles,  benefits and  interests  belonging  and accruing to Agent
     under the Security Instruments,  including,  without limitation,  liens and
     security  interests in any  collateral,  fees and payments of principal and
     interest by the Borrowers under the  Commitments on a Pro Rata basis.  Each
     Lender  shall  perform  all duties and  obligations  of Lenders  under this
     Agreement in the same  proportion  as its  ownership  interest in the Loans
     outstanding at the date of determination thereof.

          (n)  Investments.  Whenever Agent in good faith  determines that it is
     uncertain  about  how to  distribute  to  Lenders  any  funds  which it has
     received,  or  whenever  Agent in good faith  determines  that there is any
     dispute among the Lenders about how such funds should be distributed, Agent
     may choose to defer distribution of the funds which are the subject of such
     uncertainty  or  dispute.   If  Agent  in  good  faith  believes  that  the
     uncertainty  or  dispute  will  not be  promptly  resolved,  or if Agent is
     otherwise  required to invest funds  pending  distribution  to the Lenders,
     Agent  may  invest  such  funds  pending  distribution  (at the risk of the
     Borrowers).  All interest on any such investment  shall be distributed upon
     the  distribution of such investment and in the same proportions and to the
     same  Persons  as  such  investment.  All  monies  received  by  Agent  for
     distribution  to the Lenders  (other than to the Person who is Agent in its
     separate  capacity  as a Lender)  shall be held by the Agent  pending  such
     distribution  solely as Agent for such  Lenders,  and Agent  shall  have no
     equitable title to any portion thereof.

          (o) Delegation to Affiliates. The Borrowers, Guarantor and the Lenders
     agree that the Agent may delegate any of its duties

                                      -71-



     under this Agreement to any of its Affiliates. Any such Affiliate (and such
     Affiliate's directors, officers, agents and employees) which perform duties
     in connection with this Agreement shall be entitled to the same benefits of
     the  indemnification,  waiver and other protective  provisions to which the
     Agent is entitled under this Section 15 and Section 19.

          (p) Execution of Collateral Documents.  The Lenders hereby empower and
     authorize the Agent to execute and deliver the Security Instruments and all
     related financing  statements and other financing  statements,  agreements,
     documents or  instruments  that shall be necessary or appropriate to effect
     the purposes of the Security Instruments.

          (q) Collateral Releases.  The Lenders hereby empower and authorize the
     Agent to execute and deliver to the Borrowers and Guarantor on their behalf
     any  agreements,  documents,  or  instruments  as  shall  be  necessary  or
     appropriate to reflect any releases of Collateral  which shall be permitted
     by  the  terms  hereof  (including,  without  limitation,  the  release  of
     Collateral  that  Borrowers or Guarantor  are permitted to sell pursuant to
     Section  13(a)(ii)  hereof) or of any other Loan  Document  or which  shall
     otherwise  have been  approved by the  requisite  Lenders  pursuant to this
     Section 15.

          (r) Internal  Revenue  Service Forms.  At least five (5) Business Days
     prior to the first date on which interest or fees are payable hereunder for
     the account of any Lender,  each Lender that is not incorporated  under the
     laws of the United States of America,  or a state  thereof,  agrees that it
     will  deliver  to the Agent  two duly  completed  copies  of United  States
     Internal  Revenue  Service Form W-8 BEN or W-8 ECI or W-8 IMY or W-8 EXP or
     such other  form as may be  applicable  and  allowable  under the  Internal
     Revenue Code and the regulations thereunder  (collectively,  a "Withholding
     Form"),  certifying  in either case that such Lender is entitled to receive
     payments  under  this   Agreement  and  the  Notes  without   deduction  or
     withholding of any United States federal income taxes. Each Lender which so
     delivers a Withholding Form further  undertakes to deliver to the Agent two
     additional  copies of such form (or a successor form) on or before the date
     that such form expires or becomes  obsolete or after the  occurrence of any
     event requiring a change in the most

                                      -72-




     recent  Withholding Form so delivered by it, and such amendments thereto or
     extensions or renewals thereof as may be reasonably requested by the Agent,
     in each case  certifying  that such Lender is entitled to receive  payments
     under this Agreement and the Notes without  deduction or withholding of any
     United States  federal  income taxes,  unless an event  (including  without
     limitation any change in treaty,  law or regulation)  has occurred prior to
     the date on which any such  delivery  would  otherwise  be  required  which
     renders all such Withholding Forms inapplicable or which would prevent such
     Lender from duly completing and delivering any such  Withholding  Form with
     respect to it and such  Lender  advises the Agent that it is not capable of
     receiving  payments  without any deduction or  withholding of United States
     federal income tax.

          (s) Syndication  Agent. The Lender identified in this Agreement as the
     Syndication Agent shall not have any right, power,  obligation,  liability,
     responsibility  or duty under this Agreement other than those applicable to
     all Lenders as such. Without limiting the foregoing,  the Syndication Agent
     shall  not have or be  deemed  to have a  fiduciary  relationship  with any
     Lender. Each Lender hereby makes the same  acknowledgments  with respect to
     the  Syndication  Agent as it makes  with  respect  to the Agent in Section
     15(f).

     16. Exercise of Rights. No failure to exercise, and no delay in exercising,
on the part of the Agent or the Lenders,  any right hereunder shall operate as a
waiver thereof,  nor shall any single or partial  exercise  thereof preclude any
other or further exercise thereof or the exercise of any other right. The rights
of the Agent and the Lenders  hereunder shall be in addition to all other rights
provided by law.

     17. Notices. Any notices or other  communications  required or permitted to
be given by this  Agreement or any other  documents or  instruments  referred to
herein must be given in writing (which may be by bank wire,  telecopy or similar
writing) and shall be given to the party to whom such notice or communication is
directed at the address or telecopy number of such party as follows:

by the Agent.

                                      -74-



     18.  Expenses.  The Borrowers  shall pay (i) all  reasonable  and necessary
out-of-pocket expenses of the Agent, including reasonable fees and disbursements
of special  counsel for the Agent,  in connection  with the  preparation of this
Agreement,  any  waiver or  consent  hereunder  or any  amendment  hereof or any
Default or Event of Default  or alleged  Default or Event of Default  hereunder,
(ii) all reasonable and necessary out-of-pocket expenses of the Agent, including
reasonable fees and disbursements of special counsel for the Agent in connection
with  the  preparation  of any  participation  agreement  for a  participant  or
participants  or any  amendment  thereof  and (iii) if a Default  or an Event of
Default occurs, all reasonable and necessary  out-of-pocket expenses incurred by
the  Lenders,  including  reasonable  fees  and  disbursements  of  counsel,  in
connection  with such  Default  and Event of Default  and  collection  and other
enforcement proceedings resulting therefrom.  THE BORROWERS AND GUARANTOR HEREBY
ACKNOWLEDGE  THAT COTTON,  BLEDSOE,  TIGHE & DAWSON IS SPECIAL  COUNSEL TO FIRST
AMERICAN,  AS AGENT AND AS A LENDER,  UNDER  THIS  AGREEMENT  AND THAT IT IS NOT
COUNSEL TO, NOR DOES IT REPRESENT THE BORROWERS OR GUARANTOR IN CONNECTION  WITH
THE  TRANSACTIONS  DESCRIBED IN THIS AGREEMENT.  The Borrowers and Guarantor are
relying on separate counsel in the transaction  described herein.  The Borrowers
and Guarantor shall  indemnify the Lenders against any transfer taxes,  document
taxes,  assessments or charges made by any  governmental  authority by reason of
the execution,  delivery and filing of the Loan  Documents.  The  obligations of
this Section 18 shall survive any termination of this Agreement,  the expiration
of the Loans and the payment of all indebtedness of the Borrowers to the Lenders
hereunder and under the Notes.

     19. Indemnity.  The Borrowers and Guarantor hereby,  jointly and severally,
agree to indemnify the Agent, each Lender, their respective Affiliates, and each
of their directors,  officers, and employees (the "Indemnified Parties") against
all losses,  claims,  damages,  penalties,  judgments,  liabilities and expenses
(including,  without limitation,  all attorney's fees and expenses of litigation
or preparation  therefor of any Indemnified  Party) which any of them may pay or
incur arising out of or relating to this  Agreement,  the other Loan  Documents,
the transactions  contemplated  hereby or the direct or indirect  application or
proposed  application  of the proceeds of any Loan  hereunder even if any of the
foregoing   arises  out  of  the  ordinary   negligence  of  the  party  seeking

                                      -75-


indemnification  except  to the  extent  that  they  are  determined  in a final
non-appealable  judgment by a court of competent  jurisdiction  to have resulted
from  the  gross   negligence  or  willful   misconduct  of  the  party  seeking
indemnification.  The  indemnity  set forth  herein  shall be in addition to any
other   obligations  or  liabilities  of  the  Borrowers  or  Guarantor  to  any
Indemnified Party hereunder or at common law or otherwise, and shall survive any
termination  of this  Agreement,  the expiration of the Loans and the payment of
all indebtedness of the Borrowers to the Lenders  hereunder and under the Notes.
THE PARTIES  INTEND FOR THE  PROVISIONS  OF THIS SECTION TO APPLY TO AND PROTECT
EACH INDEMNIFIED  PARTY FROM THE CONSEQUENCES OF ANY LIABILITY  INCLUDING STRICT
LIABILITY  IMPOSED OR THREATENED TO BE IMPOSED ON THE INDEMNIFIED  PARTY AS WELL
AS FROM THE  CONSEQUENCES OF ITS OWN NEGLIGENCE,  WHETHER OR NOT THAT NEGLIGENCE
IS THE SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF ANY CLAIM.

     20.  Non-Liability of Lenders.  The relationship  between the Borrowers and
Guarantor  on the one hand and the Lenders and the Agent on the other hand shall
be solely  that of  borrower/guarantor  and  lender.  Neither  the Agent nor any
Lender shall have any  fiduciary  responsibility  to the Borrowers or Guarantor.
Neither the Agent nor any Lender undertakes any  responsibility to the Borrowers
or  Guarantor  to review or inform the  Borrowers  or Guarantor of any matter in
connection  with any  phase  of the  Borrowers'  or  Guarantor's  businesses  or
operations.  The Borrowers  and  Guarantor  agree that neither the Agent nor any
Lender shall have any liability to the Borrowers or Guarantor  (whether sounding
in tort,  contract  or  otherwise)  for  losses  suffered  by the  Borrowers  or
Guarantor  in  connection  with,  arising  out of, or in any way related to, the
transactions contemplated and the relationship established by this Agreement and
the other Loan Documents,  or any act, omission or event occurring in connection
therewith, unless it is determined in a final non-appealable judgment by a court
of competent  jurisdiction  that such loss resulted from the gross negligence or
willful misconduct of the party from which recovery is sought. Neither the Agent
nor any Lender shall have any  liability  with respect to, and the Borrowers and
Guarantor hereby waive, release and agree not to sue for, any special, indirect,
consequential  or punitive  damages  suffered by the  Borrowers  or Guarantor in
connection  with,  arising out of, or in any way related to this Agreement,  the
Loan Documents or any transaction contemplated thereby.


                                      -76-


     21.  Governing Law. THIS AGREEMENT IS BEING EXECUTED AND DELIVERED,  AND IS
INTENDED TO BE PERFORMED, IN MIDLAND, MIDLAND COUNTY, TEXAS, AND THE SUBSTANTIVE
LAWS  OF  TEXAS  SHALL  GOVERN  THE  VALIDITY,  CONSTRUCTION,   ENFORCEMENT  AND
INTERPRETATION  OF  THIS  AGREEMENT  AND ALL  OTHER  DOCUMENTS  AND  INSTRUMENTS
REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN.

     22.  Invalid  Provisions.  If any provision of this Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term of this Agreement,  such  provisions  shall be fully severable and this
Agreement  shall be  construed  and  enforced  as if such  illegal,  invalid  or
unenforceable  provision had never comprised a part of this  Agreement,  and the
remaining  provisions of the Agreement shall remain in full force and effect and
shall not be affected by the illegal,  invalid or unenforceable  provision or by
its severance from this Agreement.

     23. Maximum Interest Rate.  Regardless of any provisions  contained in this
Agreement or in any other  documents  and  instruments  referred to herein,  the
Lenders shall never be deemed to have  contracted for or be entitled to receive,
collect or apply as  interest  on the Notes any amount in excess of the  Maximum
Rate, and in the event any Lender ever receives, collects or applies as interest
any such excess,  or if an acceleration of the maturities of any Notes or if any
prepayment by the Borrowers results in the Borrowers having paid any interest in
excess of the Maximum Rate, such amount which would be excessive  interest shall
be applied to the  reduction  of the unpaid  principal  balance of the Notes for
which such excess was  received,  collected  or applied,  and, if the  principal
balance of such Note is paid in full,  any remaining  excess shall  forthwith be
paid to the Borrowers. All sums paid or agreed to be paid to the Lenders for the
use, forbearance or detention of the indebtedness  evidenced by the Notes and/or
this Agreement  shall, to the extent  permitted by applicable law, be amortized,
prorated,  allocated and spread  throughout  the full term of such  indebtedness
until  payment in full so that the rate or amount of interest on account of such
indebtedness does not exceed the Maximum Rate. In determining whether or not the
interest paid or payable under any specific contingency exceeds the Maximum Rate
of interest  permitted  by law,  the  Borrowers  and the Lenders  shall,  to the
maximum  extent   permitted   under   applicable  law,  (i)   characterize   any
non-principal  payment as an expense,  fee or premium,  rather than as


                                      -77-



interest;  and (ii) exclude  voluntary  prepayments and the effect thereof;  and
(iii) compare the total amount of interest  contracted for,  charged or received
with the total  amount of interest  which could be  contracted  for,  charged or
received  throughout  the entire  contemplated  term of the Note at the  Maximum
Rate.

     For  purposes  of  Section  303 of the Texas  Finance  Code,  to the extent
applicable to any Lender or Agent,  Borrowers  agree that the Maximum Rate shall
be the "weekly ceiling" as defined in said Chapter, provided that such Lender or
Agent, as applicable,  may also rely, to the extent permitted by applicable laws
of the State of Texas and the United States of America,  on alternative  maximum
rates of interest under the Texas Finance Code or other laws  applicable to such
Lender or Agent from time to time if greater.

     24.  Amendments.  This  Agreement  may be amended only by an  instrument in
writing  executed  by an  authorized  officer  of the  party  against  whom such
amendment is sought to be enforced.  No  modification or waiver of any provision
of the Loan  Documents,  including this  Agreement,  or the Notes nor consent to
departure  therefrom,  shall be effective  unless in writing signed by Borrowers
and/or Guarantor, as applicable,  and Majority Lenders (or by Agent on behalf of
Majority  Lenders)  subject to the  additional  requirements  of  Section  15(f)
hereof, to the extent applicable.  No such consent or waiver shall extend beyond
the particular case and purpose involved.  No notice or demand given in any case
shall constitute a waiver of the right to take other action in the same, similar
or other  circumstances  without  such  notice or demand.  No  amendment  of any
provision of this Agreement relating to the Agent shall be effective without the
written consent of the Agent.

     25.  Multiple  Counterparts.  This Agreement may be executed in a number of
identical separate counterparts,  each of which for all purposes is to be deemed
an original, but all of which shall constitute,  collectively, one agreement. No
party to this  Agreement  shall  be bound  hereby  until a  counterpart  of this
Agreement has been executed by all parties hereto.

     26.  Conflict.  In the event any term or provision  hereof is  inconsistent
with or  conflicts  with any  provision  of the  Loan  Documents,  the  terms or
provisions contained in this Agreement shall be controlling.

                                      -78-



     27. Survival. All covenants, agreements, undertakings,  representations and
warranties  made in the Loan Documents,  including this Agreement,  the Notes or
other  documents and  instruments  referred to herein shall survive all closings
hereunder and shall not be affected by any investigation made by any party.

     28.  Parties Bound.  This Agreement  shall be binding upon and inure to the
benefit of the parties hereto and their respective successors,  assigns,  heirs,
legal representatives and estates, provided, however, that neither the Borrowers
nor the Guarantor may,  without the prior written consent of all of the Lenders,
assign any rights, powers, duties or obligations hereunder.

     29. Assignments and Participations.

          (a) Each Lender  shall have the right to sell,  assign or transfer all
     or any  part of its  Note or  Notes,  its  Commitment  and its  rights  and
     obligations  hereunder  to  one  or  more  Affiliates,  Lenders,  financial
     institutions,  pension plans,  insurance  companies,  investment  funds, or
     similar  Persons who are Eligible  Assignees or to a Federal  Reserve Bank;
     provided,  that  each  sale,  assignment  or  transfer  (other  than  to an
     Affiliate, a Lender or a Federal Reserve Bank) shall require the consent of
     Agent and the Borrowers,  which consents will not be unreasonably withheld;
     provided,  however,  that  if an  Event  of  Default  has  occurred  and is
     continuing,  the consent of the Borrower  shall not be  required.  Any such
     assignee,  transferee or recipient  shall have, to the extent of such sale,
     assignment,  or transfer,  the same rights,  benefits and obligations as it
     would if it were such  Lender  and a holder of such  Note,  Commitment  and
     rights and obligations, including, without limitation, the right to vote on
     decisions  requiring consent or approval of all Lenders or Majority Lenders
     and the  obligation to fund its  Commitment;  provided,  that (1) each such
     sale,  assignment,  or transfer (other than to an Affiliate,  a Lender or a
     Federal  Reserve Bank) shall be in an aggregate  principal  amount not less
     than $5,000,000,  (2) each remaining Lender shall at all times maintain its
     Commitment then outstanding in an aggregate principal amount at least equal
     to $5,000,000; (3) each such sale, assignment or transfer shall be of a Pro
     Rata portion of such Lender's  Commitment,  (4) no Lender may offer to sell
     its Note or Notes, Commitment,  rights and obligations or interests therein
     in violation of any  securities  laws; and (5) no

                                      -79-



     such  assignments  (other  than to a Federal  Reserve  Bank)  shall  become
     effective until the assigning Lender and its assignee delivers to Agent and
     Borrowers an  Assignment  and  Acceptance  and the Note or Notes subject to
     such  assignment and other  documents  evidencing any such  assignment.  An
     assignment fee in the amount of $2,500 for each such assignment (other than
     to an Affiliate,  a Lender or the Federal  Reserve Bank) will be payable to
     Agent by assignor or  assignee.  Within  five (5)  Business  Days after its
     receipt of copies of the Assignment and Acceptance and the other  documents
     relating  thereto and the Note or Notes,  the  Borrowers  shall execute and
     deliver to Agent (for  delivery  to the  relevant  assignee)  a new Note or
     Notes  evidencing such assignee's  assigned  Commitment and if the assignor
     Lender has retained a portion of its Commitment,  a replacement Note in the
     principal  amount of the  Commitment  retained by the  assignor  (except as
     provided in the last  sentence of this  paragraph (a) such Note or Notes to
     be in exchange  for,  but not in payment of, the Note or Notes held by such
     Lender).  On and after the effective date of an assignment  hereunder,  the
     assignee  shall for all purposes be a Lender,  party to this  Agreement and
     any other Loan  Document  executed  by the  Lenders  and shall have all the
     rights and  obligations of a Lender under the Loan  Documents,  to the same
     extent as if it were an original party thereto,  and no further  consent or
     action by Borrowers,  Lenders or the Agent shall be required to release the
     transferor Lender with respect to its Commitment  assigned to such assignee
     and the transferor Lender shall henceforth be so released.

          (b) Each Lender shall have the right to grant participations in all or
     any part of such  Lender's  Notes and  Commitment  hereunder to one or more
     pension   plans,   investment   funds,   insurance   companies,   financial

                                 REVOLVING NOTE

$10,000,000.00                   Midland, Texas              December 20, 2002

     FOR VALUE  RECEIVED,  the undersigned  PARALLEL  PETROLEUM  CORPORATION,  a
Delaware   corporation,   and  PARALLEL,   L.P.,  a  Texas  limited  partnership
(hereinafter  collectively  referred  to as  "Borrowers"),  hereby  jointly  and
severally and  unconditionally  promise to pay to the order of WESTERN  NATIONAL
BANK (the  "Lender") at the offices of FIRST AMERICAN BANK, SSB (the "Agent") in
Midland  County,  Texas,  the  principal  sum of TEN MILLION AND NO/100  DOLLARS
($10,000,000.00),  or so much thereof as may be advanced and  outstanding at any
time or from time to time  pursuant  to the  Credit  Agreement  (as  hereinafter
defined) in lawful money of the United States of America  together with interest
from the date hereof until paid at the rates specified in the Credit  Agreement.
All payments of principal  and interest due hereunder are payable at the offices
of Agent at 1004 N. Big Spring,  Suite 121,  Midland,  Texas  79701,  or at such
other address as Lender shall designate in writing to Borrowers.

     The  principal  and all  accrued  interest  on this  Note  shall be due and
payable in accordance with the terms and provisions of the Credit Agreement.

     This Note is executed  pursuant to that certain  First Amended and Restated
Credit  Agreement dated of even date herewith between  Borrowers,  the Guarantor
named  therein,   First   American  Bank,   SSB,  as  Joint  Lead  Arranger  and
Administrative Agent, BNP Paribas, as Joint Lead Arranger and Syndication Agent,
and the Lenders from time to time  parties  thereto (as the same may be modified
or amended from time to time, the "Credit  Agreement"),  and is one of the Notes
referred  to therein.  Reference  is made to the Credit  Agreement  and the Loan
Documents (as that term is defined in the Credit  Agreement)  for a statement of
prepayment rights and obligations of Borrowers, for a statement of the terms and
conditions  under  which  the due date of this Note may be  accelerated  and for
statements  regarding  other  matters  affecting  this Note  (including  without
limitation  the  obligations  of the holder hereof to advance  funds  hereunder,
principal and interest payment due dates,  voluntary and mandatory  prepayments,
exercise of rights and  remedies,  payment of attorneys'  fees,  court costs and
other costs of  collection  and certain  waivers by Borrowers  and others now or
hereafter obligated for payment of any sums due hereunder).  Upon the occurrence
of an Event of Default, as that term is defined in the Credit Agreement and Loan
Documents,  the Agent may declare



forthwith to be entirely and immediately  due and payable the principal  balance
hereof and the interest accrued hereon, and the Lender shall have all rights and
remedies of the Lender under the Credit Agreement and Loan Documents.  This Note
may be  prepaid  in  accordance  with the terms  and  provisions  of the  Credit
Agreement.

     Regardless of any provision contained in this Note, the holder hereof shall
never be entitled to receive,  collect or apply,  as interest on this Note,  any
amount in excess of the  Maximum  Rate (as such term is  defined  in the  Credit
Agreement),  and, if the holder hereof ever  receives,  collects,  or applies as
interest,  any such amount which would be excessive interest, it shall be deemed
a partial  prepayment  of principal and treated  hereunder as such;  and, if the
indebtedness  evidenced  hereby  is paid in full,  any  remaining  excess  shall
forthwith be paid to Borrower.  In determining  whether or not the interest paid
or payable, under any specific contingency,  exceeds the Maximum Rate, Borrowers
and the holder hereof shall, to the maximum extent  permitted  under  applicable
law (i) characterize  any  non-principal  payment as an expense,  fee or premium
rather than as interest,  (ii)  exclude  voluntary  prepayments  and the effects
thereof,  and (iii)  spread the total amount of interest  throughout  the entire
contemplated  term of the obligations  evidenced by this Note and/or referred to
in the Credit  Agreement so that the  interest  rate is uniform  throughout  the
entire term of this Note;  provided  that, if this Note is paid and performed in
full prior to the end of the full contemplated term thereof; and if the interest
received for the actual  period of existence  thereof  exceeds the Maximum Rate,
the holder  hereof shall refund to Borrowers the amount of such excess or credit
the amount of such excess against the  indebtedness  evidenced  hereby,  and, in
such event, the holder hereof shall not be subject to any penalties  provided by
any laws for contracting for, charging,  taking, reserving or receiving interest
in excess of the Maximum Rate.

     If any payment of  principal or interest on this Note shall become due on a
day other than a Business Day (as such term is defined in the Credit Agreement),
such  payment  shall  be made  on the  next  succeeding  Business  Day and  such
extension  of time  shall in such case be  included  in  computing  interest  in
connection with such payment.

     If this Note is placed in the hands of an attorney for collection, or if it
is collected  through any legal proceeding at law or in equity or in bankruptcy,
receivership  or other court  proceedings,  Borrowers  agree to pay all costs of
collection, including, but not limited to, court costs and reasonable attorneys'
fees.

                                      -2-



     Borrowers and each surety, endorser,  guarantor and other party ever liable
for payment of any sums of money  payable on this Note,  jointly  and  severally
waive presentment and demand for payment,  notice of intention to accelerate the
maturity,  protest, notice of protest and nonpayment,  as to this Note and as to
each and all installments hereof, and agree that their liability under this Note
shall not be affected by any renewal or extension in the time of payment hereof,
or in any  indulgences,  or by any  release  or change in any  security  for the
payment of this Note,  and hereby  consent to any and all renewals,  extensions,
indulgences, releases or changes.

     This  Note  shall be  governed  by and  construed  in  accordance  with the
applicable  laws of the United  States of  America  and the laws of the State of
Texas.

     THIS  INSTRUMENT  SECURES A LINE OF CREDIT  USED  PRIMARILY  FOR  BUSINESS,
COMMERCIAL OR AGRICULTURAL PURPOSES.

         This Note is, to the extent of $815,000.00, executed in renewal,
extension and rearrangement, but not in extinguishment or novation, of that
certain Revolving Note dated July 17, 2002, in the original principal amount of
$100,000,000, executed by Parallel Petroleum Corporation and payable to the
order of First American Bank, SSB.

     THIS  WRITTEN  NOTE,  THE CREDIT  AGREEMENT  AND THE OTHER  LOAN  DOCUMENTS
REPRESENT THE FINAL  AGREEMENTS  BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR  SUBSEQUENT  ORAL  AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     EXECUTED as of the date and year first above written.

a partial  prepayment  of principal and treated  hereunder as such;  and, if the
indebtedness  evidenced  hereby  is paid in full,  any  remaining  excess  shall
forthwith be paid to Borrower.  In determining  whether or not the interest paid
or payable, under any specific contingency,  exceeds the Maximum Rate, Borrowers
and the holder hereof shall, to the maximum extent  permitted  under  applicable
law (i) characterize  any  non-principal  payment as an expense,  fee or premium
rather than as interest,  (ii)  exclude  voluntary  prepayments  and the effects
thereof,  and (iii)  spread the total amount of interest  throughout  the entire
contemplated  term of the obligations  evidenced by this Note and/or referred to
in the Credit  Agreement so that the  interest  rate is uniform  throughout  the
entire term of this Note;  provided  that, if this Note is paid and performed in
full prior to the end of the full contemplated term thereof; and if the interest
received for the actual  period of existence  thereof  exceeds the Maximum Rate,
the holder  hereof shall refund to Borrowers the amount of such excess or credit
the amount of such excess against the  indebtedness  evidenced  hereby,  and, in
such event, the holder hereof shall not be subject to any penalties  provided by
any laws for contracting for, charging,  taking, reserving or receiving interest
in excess of the Maximum Rate.

     If any payment of  principal or interest on this Note shall become due on a
day other than a Business Day (as such term is defined in the Credit Agreement),
such  payment  shall  be made  on the  next  succeeding  Business  Day and  such
extension  of time  shall in such case be  included  in  computing  interest  in
connection with such payment.

     If this Note is placed in the hands of an attorney for collection, or if it
is collected  through any legal proceeding at law or in equity or in bankruptcy,
receivership  or other court  proceedings,  Borrowers  agree to pay all costs of

                                      -2-



collection, including, but not limited to, court costs and reasonable attorneys'
fees.

     Borrowers and each surety, endorser,  guarantor and other party ever liable
for payment of any sums of money  payable on this Note,  jointly  and  severally
waive presentment and demand for payment,  notice of intention to accelerate the
maturity,  protest, notice of protest and nonpayment,  as to this Note and as to
each and all installments hereof, and agree that their liability under this Note
shall not be affected by any renewal or extension in the time of payment hereof,
or in any  indulgences,  or by any  release  or change in any  security  for the
payment of this Note,  and hereby  consent to any and all renewals,  extensions,
indulgences, releases or changes.

     This  Note  shall be  governed  by and  construed  in  accordance  with the
applicable  laws of the United  States of  America  and the laws of the State of
Texas.

                                 REVOLVING NOTE

$45,000,000.00                   Midland, Texas              December 20, 2002

     FOR VALUE  RECEIVED,  the undersigned  PARALLEL  PETROLEUM  CORPORATION,  a
Delaware   corporation,   and  PARALLEL,   L.P.,  a  Texas  limited  partnership
(hereinafter  collectively  referred  to as  "Borrowers"),  hereby  jointly  and
severally  and  unconditionally  promise  to pay to the order of FIRST  AMERICAN
BANK,  SSB (the  "Lender")  at the  offices  of FIRST  AMERICAN  BANK,  SSB (the
"Agent") in Midland County,  Texas, the principal sum of FORTY-FIVE  MILLION AND
NO/100  DOLLARS  ($45,000,000.00),  or so much  thereof as may be  advanced  and
outstanding  at any time or from time to time  pursuant to the Credit  Agreement
(as  hereinafter  defined)  in lawful  money of the  United  States  of  America
together with interest from the date hereof until paid at the rates specified in
the Credit  Agreement.  All payments of principal and interest due hereunder are
payable at the offices of Agent at 1004 N. Big Spring, Suite 121, Midland, Texas
79701,  or at such  other  address  as Lender  shall  designate  in  writing  to
Borrowers.

     The  principal  and all  accrued  interest  on this  Note  shall be due and
payable in accordance with the terms and provisions of the Credit Agreement.

     This Note is executed  pursuant to that certain  First Amended and Restated
Credit  Agreement dated of even date herewith between  Borrowers,  the Guarantor
named  therein,   First   American  Bank,   SSB,  as  Joint  Lead  Arranger  and

Documents (as that term is defined in the Credit  Agreement)  for a statement of
prepayment rights and obligations of Borrowers, for a statement of the terms and
conditions  under  which  the due date of this Note may be  accelerated  and for
statements  regarding  other  matters  affecting  this Note  (including  without
limitation  the  obligations  of the holder hereof to advance  funds  hereunder,
principal and interest payment due dates,  voluntary and mandatory  prepayments,
exercise of rights and  remedies,  payment of attorneys'  fees,  court costs and
other costs of  collection  and certain  waivers by Borrowers  and others now or
hereafter obligated for payment of any sums due hereunder).  Upon the occurrence
of an Event of Default, as that term is defined in the Credit Agreement and Loan
Documents,  the Agent may declare




forthwith to be entirely and immediately  due and payable the principal  balance
hereof and the interest accrued hereon, and the Lender shall have all rights and

Agreement.

     Regardless of any provision contained in this Note, the holder hereof
shall never be entitled to receive, collect or apply, as interest on this Note,
any amount in excess of the Maximum Rate (as such term is defined in the Credit
Agreement), and, if the holder hereof ever receives, collects, or applies as
interest, any such amount which would be excessive interest, it shall be deemed
a partial prepayment of principal and treated hereunder as such; and, if the
indebtedness evidenced hereby is paid in full, any remaining excess shall
forthwith be paid to Borrower. In determining whether or not the interest paid
or payable, under any specific contingency, exceeds the Maximum Rate, Borrowers
and the holder hereof shall, to the maximum extent permitted under applicable
law (i) characterize any non-principal payment as an expense, fee or premium
rather than as interest, (ii) exclude voluntary prepayments and the effects
thereof, and (iii) spread the total amount of interest throughout the entire
contemplated term of the obligations evidenced by this Note and/or referred to
in the Credit Agreement so that the interest rate is uniform throughout the
entire term of this Note; provided that, if this Note is paid and performed in
full prior to the end of the full contemplated term thereof; and if the interest
received for the actual period of existence thereof exceeds the Maximum Rate,
the holder hereof shall refund to Borrowers the amount of such excess or credit
the amount of such excess against the indebtedness evidenced hereby, and, in
such event, the holder hereof shall not be subject to any penalties provided by
any laws for contracting for, charging, taking, reserving or receiving interest
in excess of the Maximum Rate.

     If any payment of  principal or interest on this Note shall become due on a
day other than a Business Day (as such term is defined in the Credit Agreement),
such  payment  shall  be made  on the  next  succeeding  Business  Day and  such
extension  of time  shall in such case be  included  in  computing  interest  in
connection with such payment.

     If this Note is placed in the hands of an attorney for collection, or if it
is collected  through any legal proceeding at law or in equity or in bankruptcy,
receivership  or other court  proceedings,  Borrowers  agree to pay all costs of

                                      -2-



collection, including, but not limited to, court costs and reasonable attorneys'
fees.

     Borrowers and each surety, endorser,  guarantor and other party ever liable
for payment of any sums of money  payable on this Note,  jointly  and  severally
waive presentment and demand for payment,  notice of intention to accelerate the
maturity,  protest, notice of protest and nonpayment,  as to this Note and as to
each and all installments hereof, and agree that their liability under this Note
shall not be affected by any renewal or extension in the time of payment hereof,

payment of this Note,  and hereby  consent to any and all renewals,  extensions,
indulgences, releases or changes.

                                    GUARANTY

     THIS  GUARANTY  (this  "Guaranty")  is made as of the 20th day of December,
2002,  by  PARALLEL,   L.L.C,  a  Delaware   limited   liability   company  (the
"Guarantor"),  in favor of the Agent, for the benefit of the Lenders,  under the
Credit Agreement referred to below;

                                   WITNESSETH:

     WHEREAS, PARALLEL PETROLEUM CORPORATION, a Delaware corporation ("PPC") and
PARALLEL,  L.P., a Texas limited  partnership  ("PLP") (PPC and PLP collectively
are hereinafter referred to as the "Principal"), Guarantor, FIRST AMERICAN BANK,
SSB, a state savings bank,  having its principal  office in Midland,  Texas,  as
Joint Lead Arranger and  Administrative  Agent (the  "Agent"),  BNP PARIBAS,  as
Joint  Lead  Arranger  and  Syndication   Agent,  and  certain  other  financial
institutions from time to time parties thereto (the "Lenders") have entered into
a  certain  First  Amended  and  Restated  Credit  Agreement  dated of even date
herewith  (as same may be amended or  modified  from time to time,  the  "Credit
Agreement"),  providing,  subject  to the  terms  and  conditions  thereof,  for
extensions of credit to be made by the Lenders to the Principal;

     WHEREAS, it is a condition precedent to the Agent and the Lenders executing
the Credit  Agreement that Guarantor  execute and deliver this Guaranty  whereby
the Guarantor shall guarantee the payment when due, subject to Section 9 hereof,
of all Guaranteed Obligations and Rate Management Obligations, as defined below;
and

     WHEREAS,  in  consideration  of the  financial  and other  support that the
Principal  has provided,  and such  financial and other support as the Principal
may in the future provide, to the Guarantor,  and in order to induce the Lenders
and the Agent to enter  into the Credit  Agreement,  and the  Lenders  and their
Affiliates  to enter  into one or more  Rate  Management  Transactions  with the
Principal, and because the Guarantor has determined that executing this Guaranty
is in its interest and to its  financial  benefit,  the  Guarantor is willing to
guarantee the obligations of the Principal under the Credit Agreement, any Note,
any Rate Management Transaction, and the other Loan Documents;



     NOW,  THEREFORE,  in  consideration  of the  premises  and  other  good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto agree as follows:

Lender arising out of or pursuant to the provisions of the Credit Agreement, the
Notes and other Loan Documents, (ii) all Rate Management Obligations,  (iii) all
indebtedness,  obligations and liabilities of Principal, or either Principal, to

unliquidated,  joint,  several or joint and several,  and  regardless of whether
such  indebtedness,  obligations and liabilities may, prior to their acquisition
by any  Lender,  be or have  been  payable  to or in favor of a third  party and

make such  acquisitions from third parties),  including  without  limitation all
indebtedness,  obligations and liabilities of Principal, or either Principal, to
any  Lender now  existing  or  hereafter  arising  by note,  draft,  acceptance,
guaranty,  endorsement,  letter  of  credit,  assignment,  purchase,  overdraft,
discount, indemnity agreement or otherwise, (iv) all accrued but unpaid interest
on any of the  indebtedness  described  in (i),  (ii) and (iii)  above,  (v) all

and all Rate Management  Transactions  with Agent or a Lender or an Affiliate of
Agent or a Lender,  and (ii) any and all  cancellations,  buy backs,  reversals,

                                      -2-




     SECTION 1.2. Terms in Credit Agreement. Other capitalized terms used herein
but not defined herein shall have the meaning set forth in the Credit Agreement.

     SECTION 2.1. Representations and Warranties. The Guarantor represents and
warrants (which representations and warranties shall be deemed to have been
renewed upon each Borrowing Date under the Credit Agreement) that:

          (a) It is a corporation, partnership or limited liability company duly
     and  properly  incorporated  or  organized,  as the  case  may be,  validly
     existing  and (to the extent such  concept  applies to such entity) in good
     standing  under  the  laws  of  its   jurisdiction  of   incorporation   or
     organization  and has all  requisite  authority  to conduct its business in
     each jurisdiction in which its business is conducted.

          (b) It has the power and  authority  and legal  right to  execute  and
     deliver  this  Guaranty  and to  perform  its  obligations  hereunder.  The
     execution  and delivery by it of this Guaranty and the  performance  of its
     obligations  hereunder  have been  duly  authorized  by  proper  corporate,
     partnership or limited  liability  company  proceedings,  and this Guaranty
     constitutes a legal, valid and binding obligation of Guarantor  enforceable
     against it in accordance with its terms,  except as  enforceability  may be
     limited  by general  principles  of equity and  bankruptcy,  insolvency  or
     similar laws affecting the enforcement of creditors' rights generally.

          (c) Neither the execution and delivery by it of this Guaranty, nor the
     consummation of the transactions herein  contemplated,  nor compliance with
     the provisions  hereof will violate (i) any law, rule,  regulation,  order,
     writ,  judgment,  injunction,  decree or award  binding on it or any of its
     subsidiaries  or  (ii)  its  articles  or  certificate  of   incorporation,
     partnership agreement, limited liability company agreement,  certificate of
     partnership, articles or certificate of organization, by-laws, or operating
     or other management agreement,  as the case may be, or (iii) the provisions
     of  any  indenture,  instrument  or  agreement  to  which  it or any of its
     subsidiaries is a party or is subject, or by which it, or its Property,  is
     bound, or conflict with or constitute a default  thereunder,  or result in,
     or  require,  the  creation  or  imposition  of any Lien  in,  of or on the
     property of Guarantor or a subsidiary  thereof pursuant to the terms of any
     such indenture,  instrument or agreement. No order, consent,  adjudication,
     approval, license, authorization, or validation of, or filing, recording or
     registration  with,  or  exemption  by, or other  action in  respect of any
     governmental or public body or authority, or any subdivision thereof, which
     has not been obtained by it or any of its  subsidiaries,  is required to be
     obtained by it or any of its

                                      -3-



     subsidiaries in connection with the execution and delivery of this Guaranty
     or the  performance  by it of its  obligations  hereunder or the  legality,
     validity, binding effect or enforceability of this Guaranty.

          SECTION 2.2. Covenants. The Guarantor covenants that, so long as any
Lender has any Commitment outstanding under the Credit Agreement, any
Reimbursement Obligations remain outstanding, any Rate Management Transaction
remains in effect or any of the Guaranteed Obligations shall remain unpaid, that
it will, and, if necessary, will enable the Principal to, fully comply with
those covenants and agreements set forth in the Credit Agreement.

     SECTION 3. The Guaranty.  Subject to Section 9 hereof, the Guarantor hereby
absolutely and unconditionally guarantees, as primary obligor and not as surety,
the full and punctual payment (whether at stated maturity,  upon acceleration or
early termination or otherwise,  and at all times thereafter) and performance of
the Guaranteed  Obligations,  including  without  limitation any such Guaranteed
Obligations   incurred  or  accrued  during  the  pendency  of  any  bankruptcy,
insolvency,  receivership or other similar proceeding, whether or not allowed or
allowable in such  proceeding.  Upon failure by the Principal to pay  punctually
any such amount,  the Guarantor  agrees that it shall forthwith on demand pay to
the Agent for the benefit of the Lenders and, if applicable,  their  Affiliates,
the amount not so paid at the place and in the  manner  specified  in the Credit
Agreement,  any Note,  any Rate  Management  Transaction  or the  relevant  Loan
Document,  as the case may be. This Guaranty is a guaranty of payment and not of
collection.  The  Guarantor  waives  any right to  require  any  Lender,  or any
Affiliate of any Lender, to sue the Principal, any other guarantor, or any other
Person obligated for all or any part of the Guaranteed Obligations, or otherwise
to enforce its payment  against any  Collateral  securing all or any part of the
Guaranteed Obligations.

     SECTION  4.  Guaranty  Unconditional.  Subject  to  Section 9  hereof,  the
obligations of the Guarantor  hereunder shall be unconditional and absolute and,
without  limiting  the  generality  of the  foregoing,  shall  not be  released,
discharged or otherwise affected by:

          (i) any extension, renewal, settlement,  compromise, waiver or release
     in respect of any of the  Guaranteed  Obligations,  by  operation of law or
     otherwise,  or  any  obligation  of  any  other  guarantor  of  any  of the
     Guaranteed  Obligations,  or any  default,  failure  or delay,  willful  or
     otherwise, in the payment or performance of the Guaranteed Obligations;

          (ii) any  modification  or  amendment of or  supplement  to the Credit
     Agreement,  any Note,  any Rate  Management  Transaction  or any other Loan
     Document;

                                      -4-


          (iii)  any  release,  nonperfection  or  invalidity  of any  direct or
     indirect  security for any  obligation  of the  Principal  under the Credit
     Agreement,   any  Note,  the  Security  Instrument,   any  Rate  Management
     Transaction,  any other  Loan  Document,  or any  obligations  of any other
     guarantor of any of the Guaranteed Obligations, or any action or failure to
     act by the Agent, any Lender or any Affiliate of any Lender with respect to
     any collateral securing all or any part of the Guaranteed Obligations;

          (iv) any change in the corporate existence,  structure or ownership of
     the Principal or any other guarantor of any of the Guaranteed  Obligations,
     or any insolvency,  bankruptcy,  reorganization or other similar proceeding
     affecting  the  Principal,   or  any  other  guarantor  of  the  Guaranteed
     Obligations,  or its assets or any  resulting  release or  discharge of any
     obligation  of  the  Principal,  or  any  other  guarantor  of  any  of the
     Guaranteed Obligations;

          (v) the  existence  of any  claim,  setoff or other  rights  which the
     Guarantor may have at any time against the Principal,  any other  guarantor
     of any of the Guaranteed  Obligations,  the Agent,  any Lender or any other
     Person, whether in connection herewith or any unrelated transactions;

          (vi) any  invalidity  or  unenforceability  relating to or against the
     Principal, or any other guarantor of any of the Guaranteed Obligations, for
     any  reason  related  to  the  Credit   Agreement,   any  Rate   Management
     Transaction, any other Loan Document, or any provision of applicable law or
     regulation  purporting  to prohibit  the payment by the  Principal,  or any
     other  guarantor  of the  Guaranteed  Obligations,  of the  principal of or
     interest on any Note or any other amount payable by the Principal under the
     Credit  Agreement,  any Note, any Rate Management  Transaction or any other
     Loan Document; or

          (vii)  any other  act or  omission  to act or delay of any kind by the
     Principal,  any other guarantor of the Guaranteed  Obligations,  the Agent,
     any Lender or any other Person or any other  circumstance  whatsoever which
     might,  but for the  provisions  of this  paragraph,  constitute a legal or
     equitable discharge of Guarantor's obligations hereunder.

     SECTION 5.  Discharge Only Upon Payment In Full:  Reinstatement  In Certain
Circumstances.  The Guarantor's obligations hereunder shall remain in full force
and effect until all Guaranteed Obligations shall have been indefeasibly paid in
full,  the  Commitments  under the Credit  Agreement  shall have  terminated  or
expired and all Rate Management  Transactions have

                                      -5-


terminated  or  expired.  If at any  time any  payment  of the  principal  of or
interest on any Note or any other amount  payable by the  Principal or any other
party under the Credit Agreement,  any Rate Management  Transaction or any other
Loan  Document is rescinded or must be otherwise  restored or returned  upon the
insolvency,  bankruptcy or  reorganization  of the  Principal or otherwise,  the
Guarantor's  obligations  hereunder  with  respect  to  such  payment  shall  be
reinstated as though such payment had been due but not made at such time.

     SECTION 6. Waivers.  The Guarantor  irrevocably  waives acceptance  hereof,
presentment,  demand,  protest and, to the fullest extent  permitted by law, any
notice not provided for herein,  as well as any requirement that at any time any
action be taken by any Person against the Principal,  any other guarantor of any
of the Guaranteed Obligations, or any other Person.

     SECTION  7.  Subrogation.  The  Guarantor  hereby  agrees not to assert any
right,  claim or cause of action,  including,  without  limitation,  a claim for
subrogation, reimbursement,  indemnification or otherwise, against the Principal
arising  out of or by  reason of this  Guaranty  or the  obligations  hereunder,
including,  without limitation,  the payment or securing or purchasing of any of
the  Guaranteed  Obligations  by the Guarantor  unless and until the  Guaranteed
Obligations  are  indefeasibly  paid in full,  any  commitment to lend under the
Credit  Agreement  and any  other  Loan  Documents  is  terminated  and all Rate
Management Transactions have terminated or expired.

     SECTION 8. Stay of Acceleration. If acceleration of the time for payment of
any of the Guaranteed  Obligations is stayed upon the insolvency,  bankruptcy or
reorganization  of  the  Principal,   all  such  amounts  otherwise  subject  to
acceleration  under  the  terms of the  Credit  Agreement,  any  Note,  any Rate
Management  Transaction or any other Loan Document shall  nonetheless be payable
by the Guarantor  hereunder forthwith on demand by the Agent made at the request
of the Majority Lenders.

     SECTION 9. Limitation on Obligations.

          (a) The provisions of this Guaranty are  severable,  and in any action
     or proceeding  involving any state corporate law, or any state,  federal or
     foreign bankruptcy,  insolvency,  reorganization or other law affecting the
     rights of creditors  generally,  if the obligations of Guarantor under this
     Guaranty would otherwise be held or determined to be avoidable,  invalid or
     unenforceable on account of the amount of Guarantor's  liability under this
     Guaranty, then, notwithstanding any other provision of this Guaranty to the
     contrary, the amount of such

                                      -6-




     liability shall, without any further action by the Guarantor,  the Agent or
     any Lender, be automatically limited and reduced to the highest amount that
     is valid and  enforceable as determined in such action or proceeding  (such
     highest  amount  determined   hereunder  being  the  Guarantor's   "Maximum
     Liability"). This Section 9(a) with respect to the Maximum Liability of the
     Guarantor is intended  solely to preserve the rights of the Agent hereunder
     to the maximum extent not subject to avoidance  under  applicable  law, and
     neither the  Guarantor  nor any other person or entity shall have any right
     or claim under this  Section  9(a) with  respect to the Maximum  Liability,
     except to the extent  necessary so that the  obligations  of the  Guarantor
     hereunder shall not be rendered voidable under applicable law.

          (b) The Guarantor  agrees that the Guaranteed  Obligations  may at any
     time and from time to time exceed the Maximum  Liability of the  Guarantor,
     without impairing this Guaranty or affecting the rights and remedies of the
     Agent  hereunder.  Nothing  in this  Section  9(b)  shall be  construed  to
     increase Guarantor's obligations hereunder beyond its Maximum Liability.

     SECTION 10.  Application  of Payments.  All payments  received by the Agent
hereunder shall be applied by the Agent to payment of the Guaranteed Obligations
in the following order unless a court of competent  jurisdiction shall otherwise
direct:

          (a) FIRST,  to payment of all costs and expenses of the Agent incurred
     in  connection  with  the  collection  and  enforcement  of the  Guaranteed
     Obligations or of any security  interest granted to the Agent in connection
     with any Collateral securing the Guaranteed Obligations;

          (b) SECOND,  to payment of that portion of the Guaranteed  Obligations
     constituting  accrued  and  unpaid  interest  and fees,  pro rata among the
     Lenders and their  Affiliates in accordance with the amount of such accrued
     and unpaid interest and fees owing to each of them;

          (c) THIRD,  to payment of the principal of the Guaranteed  Obligations
     then due and  unpaid  from the  Principal  to any of the  Lenders  or their
     Affiliates,  Pro Rata among the Lenders and their  Affiliates in accordance
     with the amount of such principal then due and unpaid to each of them; and

          (d) FOURTH, to payment of any Guaranteed Obligations (other than those
     listed  above)  Pro  Rata  among  those  parties  to whom  such  Guaranteed
     Obligations are due in accordance with the amounts owing to each of them.

                                      -7-




     SECTION 11. Notices. All notices,  requests and other communications to any
party  hereunder  shall be  given or made by  telecopier  or other  writing  and
telecopied,  or mailed or delivered to the intended  recipient at its address or
telecopier  number set forth on the signature pages hereof or such other address
or  telecopy  number as such party may  hereafter  specify  for such  purpose by
notice to the Agent in  accordance  with the  provisions  of  Section  17 of the
Credit  Agreement.  Except as  otherwise  provided  in this  Guaranty,  all such
communications  shall be  deemed to have been duly  given  when  transmitted  by
telecopier,  or personally  delivered or, in the case of a mailed notice sent by
certified mail  return-receipt  requested,  on the date set forth on the receipt
(provided,  that any  refusal  to accept any such  notice  shall be deemed to be
notice  thereof  as of the  time of any such  refusal),  in each  case  given or
addressed as aforesaid.

     SECTION 12. No  Waivers.  No failure or delay by the Agent or any Lender in
exercising  any right,  power or privilege  hereunder  shall operate as a waiver
thereof nor shall any single or partial  exercise  thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies  provided in this Guaranty,  the Credit  Agreement,  any
Note, any Rate  Management  Transaction  and the other Loan  Documents  shall be
cumulative and not exclusive of any rights or remedies provided by law.

     SECTION 13. No Duty to Advise. The Guarantor assumes all responsibility for
being and keeping itself  informed of the  Principal's  financial  condition and
assets,  and of all other  circumstances  bearing upon the risk of nonpayment of
the Guaranteed  Obligations  and the nature,  scope and extent of the risks that
the Guarantor  assumes and incurs under this  Guaranty,  and agrees that neither
the Agent nor any  Lender has any duty to advise the  Guarantor  of  information
known to it regarding those circumstances or risks.

     SECTION 14. Successors and Assigns. This Guaranty is for the benefit of the
Agent and the Lenders and their respective  successors and permitted assigns and
in the event of an assignment of any amounts payable under the Credit Agreement,
any Note, any Rate  Management  Transaction,  or the other Loan  Documents,  the
rights  hereunder,  to the extent  applicable to the  indebtedness  so assigned,
shall be transferred with such indebtedness. This Guaranty shall be binding upon
the Guarantor and its successors and permitted assigns.

         SECTION 15. Changes in Writing. Neither this Guaranty nor any provision
hereof may be changed, waived, discharged or terminated orally, but only in
writing signed by the Guarantor and the Agent with the consent of the Majority
Lenders.

                                      -8-


     SECTION 16. Costs of Enforcement. The Guarantor agrees to pay all costs and
expenses including,  without limitation, all court costs and attorneys' fees and
expenses  paid or  incurred by the Agent or any Lender or any  Affiliate  of any
Lender in endeavoring  to collect all or any part of the Guaranteed  Obligations
from, or in prosecuting any action against, the Principal,  the Guarantor or any
other guarantor of all or any part of the Guaranteed Obligations.

     SECTION 17.  GOVERNING  LAW;  SUBMISSION  TO  JURISDICTION;  WAIVER OF JURY
TRIAL.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE
LAW OF THE STATE OF TEXAS.  THE  GUARANTOR  HEREBY  SUBMITS TO THE  NONEXCLUSIVE
JURISDICTION  OF THE UNITED STATES  DISTRICT  COURT FOR THE WESTERN  DISTRICT OF
TEXAS (MIDLAND DIVISION) AND OF ANY TEXAS STATE COURT SITTING IN MIDLAND,  TEXAS
AND FOR  PURPOSES  OF ALL LEGAL  PROCEEDINGS  ARISING OUT OF OR RELATING TO THIS
GUARANTY (INCLUDING, WITHOUT LIMITATION, ANY OF THE OTHER LOAN DOCUMENTS) OR THE
TRANSACTIONS  CONTEMPLATED  HEREBY.  THE GUARANTOR  IRREVOCABLY  WAIVES,  TO THE
FULLEST  EXTENT  PERMITTED BY LAW, ANY  OBJECTION  WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH  PROCEEDING  BROUGHT IN SUCH A COURT
AND ANY CLAIM THAT ANY SUCH PROCEEDING  BROUGHT IN SUCH A COURT HAS BEEN BROUGHT
IN AN INCONVENIENT  FORUM. THE GUARANTOR HEREBY  IRREVOCABLY  WAIVES ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL  PROCEEDING  ARISING  OUT OF OR  RELATING TO
THIS GUARANTY OR THE TRANSACTIONS CONTEMPLATED HEREBY.

     SECTION 18. Taxes,  etc. All payments  required to be made by the Guarantor
hereunder shall be made without setoff or counterclaim and free and clear of and
without  deduction  or  withholding  for or on account of, any present or future
taxes, levies,  imposts, duties or other charges of whatsoever nature imposed by
any  government  or any  political or taxing  authority  thereof (but  excluding
income  and  franchise  taxes),  provided,  however,  that if the  Guarantor  is
required by law to make such deduction or withholding, Guarantor shall forthwith
(i) pay to the Agent or any Lender,  as applicable,  such  additional  amount as
results in the net amount  received by the Agent or any Lender,  as  applicable,
equaling  the full  amount  which  would have been  received by the Agent or any
Lender, as applicable,  had no such deduction or withholding been made, (ii) pay
the full amount deducted to the relevant authority in accordance with applicable
law,  and (iii)  furnish to the Agent or any Lender,  as  applicable,  certified
copies of official receipts  evidencing payment of such withholding taxes within
30 days after such payment is made.

                                      -9-




     SECTION 19. Setoff. Without limiting the rights of the Agent or the Lenders
under  applicable law, if all or any part of the Guaranteed  Obligations is then
due,  whether  pursuant to the  occurrence of a Default or  otherwise,  then the
Guarantor authorizes the Agent and the Lenders to apply any sums standing to the
credit of the  Guarantor  with the Agent or any Lender toward the payment of the
Guaranteed Obligations.
