Item 2.  Acquisition or Disposition of Assets

MERGER WITH UNITED MERIDIAN CORPORATION

         Effective on March 27, 1998,  United Meridian  Corporation,  a Delaware
corporation  ("UMC"),  merged  with and into  Ocean  Energy,  Inc.,  a  Delaware
corporation (the "Company"),  pursuant to an Agreement and Plan of Merger, dated
as of December 22, 1997,  as amended by an Amendment  No. 1, dated as of January
7, 1998,  and an Amendment  No. 2, dated as of February 20, 1998 (as amended the
"Merger Agreement"),  among the Company, UMC and the OEI Holding Corporation,  a
Delaware   corporation   (the  "Merger").   The  closing  of  the   transactions
contemplated by the Merger  Agreement took place on March 27, 1998.  Pursuant to
the Merger  Agreement,  the Company's  stockholders are entitled to receive 2.34
shares of common  stock,  par value $0.01 per share,  of the  Company  (the "OEI
Common Stock") for each of the  approximately  22.9 million  existing  shares of
common stock outstanding (the "Old OEI Common Stock"),  and UMC stockholders are
entitled  to  receive   1.30  shares  of  OEI  Common  Stock  for  each  of  the
approximately  35.8 million existing shares of UMC common stock, par value $0.01
per share ("UMC Common Stock)  outstanding.  This results in approximately 100.1
million shares of OEI Common Stock outstanding immediately following the Merger.
UMC  Common  Stock  and Old OEI  Common  Stock are no  longer  transferable  and
certificates  evidencing  shares of UMC Common  Stock and Old OEI  Common  Stock
represent  only the right to  receive,  without  interest,  shares of OEI Common
Stock, in accordance with the provisions of the Merger  Agreement.  Cash will be
paid in lieu of fractional  shares of OEI Common Stock.  The stockholders of the
Company and UMC  approved  the Merger at an Annual  Stockholders'  Meeting and a
Special Stockholders' Meeting, respectively, held on March 27, 1998.

         The  consideration  of the Merger was determined  through  negotiations
between  the  managements  of the  Company  and UMC and was  approved  by  their
respective  board  of  directors.  In  North  America,  the  UMC  production  is
concentrated in the Gulf Coast,  Permian Basin,  Midcontinent and Rocky Mountain
regions and in Western Canada. Internationally,  UMC operations include the West
African oil and gas producing  regions of Cote d'Ivoire and  Equatorial  Guinea,
production sharing contracts or petroleum  concession  agreements on five blocks
in Pakistan  and on one block in  Bangladesh,  and  participation  in a block in
offshore Angola. Additionally, there are two applications pending for production
sharing contracts in an additional West African nation.

         Under the Merger Agreement,  each unexpired and unexercised outstanding
Company  stock  option to  purchase  or acquire a share of Old OEI Common  Stock
under the Company's Option Plans (as defined below) was automatically  converted
into an option to  purchase  the number of shares of OEI Common  Stock  equal to
2.34 times the number of shares of Old OEI Common  Stock  which  could have been
obtained  prior to the  Merger,  at an  exercise  price per  share  equal to the
exercise  price for each such  share of Old OEI  Common  Stock  subject  to such
option divided by 2.34. The other terms of each such option, and the plans under
which they were  issued,  continue  to apply in  accordance  with  their  terms,
including any provisions providing for transfer and acceleration.

         In addition, each outstanding UMC stock option to purchase or acquire a
share of UMC Common  Stock  under the UMC Option  Plans (as  defined  below) was
converted  into an option to purchase  the number of shares of OEI Common  Stock
equal to 1.30 times the number of shares of UMC Common  Stock  which  could have
been obtained  prior to the Merger,  at an exercise price per share equal to the
exercise  price for each such share of UMC Common  Stock  subject to such option
under the UMC Option  Plans  divided  by 1.30.  The  Company  also  assumed  the
obligations  of UMC under the UMC  Option  Plans.  The other  terms of each such
option, and the UMC Option Plans under which they were issued, continue to apply
in accordance with their terms,  including any provisions providing for transfer
and acceleration.

ITEM 5.  OTHER EVENTS

         At the  Company's  1998 Annual  Meeting of  Stockholders  (the  "Annual
Meeting"),  the stockholders of the Company also approved the Ocean Energy, Inc.
1998  Long-Term  Incentive  Plan (the "1998  LTIP").  As used  herein,  the term
"Company  Option Plans" shall mean,  collectively,  the Ocean Energy,  Inc. 1994
Long-Term  Incentive Plan ("1994 LTIP"),  the Ocean Energy,  Inc. 1996 Long-Term
Incentive Plan ("1996 LTIP"), the Ocean Energy,  Inc.  Long-Term  Incentive Plan
for  Nonexecutive  Employees  ("Nonexecutive  LTIP") and the 1998 LTIP.  As used
herein,  the term "UMC  Option  Plans"  shall  mean,  collectively,  the  United
Meridian Corporation 1987 Nonqualified Stock


                                       -2-

<PAGE>



Option Plan ("UMC 1987 NQO Plan"), the United Meridian Corporation 1994 Employee
Nonqualified  Stock  Option  Plan ("UMC 1994 NQO Plan") and the United  Meridian
Corporation 1994 Outside Directors' Nonqualified Stock Option Plan ("UMC Outside
Director  Plan").  Although the  outstanding  options  under each of the Company
Option  Plans and UMC Option  Plans  (collectively,  the  "Plans")  will  remain
outstanding  (adjusted as described above), no further grants will be made under
any of  such  plans  other  than  the  1998  LTIP  and  the  Nonexecutive  LTIP.
Substantially  all  outstanding  options  granted  under the Plans  became fully
exercisable as a result of the Merger.

         At the Annual  Meeting,  the  Company's  stockholders  also elected Mr.
Flores and Thomas D. Clark,  Jr. to serve  additional  three-year terms as Class
III  Directors.  The Board of Directors of the Company  following  the effective
time of the Merger is composed  of the  following  individuals:  Robert L. Belk,
John B. Brock, Thomas D. Clark, Jr., Lodwrick M. Cook, James L. Dunlap, James C.
Flores,  Robert L. Howard, Elvis L. Mason, Charles F. Mitchell,  James L. Murdy,
David K.  Newbigging,  William W. Rucks,  IV,  Matthew R.  Simmons and Milton J.
Womack.  In addition,  stockholders  ratified the appointment of Arthur Andersen
LLP as the Company's independent auditors for the 1998 fiscal year.

         In connection  with the Merger,  on March 27, 1998, the Company entered
into  employment  agreements,  copies of which are attached  hereto as exhibits,
with John B. Brock and James C.  Flores  which  extend for an initial  period of
three years, subject to extension.  Mr. Brock and Mr. Flores will receive a base
salary  per  year  of  $475,000  and  $600,000,   respectively,  and  a  maximum
discretionary  annual  bonus of 200% of such  executive's  base salary in effect
during such year. Additionally,  the Certificate of Incorporation of the Company
was amended to increase the number of  authorized  shares of Common Stock to 250
million shares.

         Also in  connection  with the Merger,  on March 27, 1998,  the Company,
restructured its bank debt by entering into a $750,000,000 (subject to borrowing
base  limitations)  Revolving  Credit Facility among the Company,  Ocean Energy,
Inc., a Louisiana  corporation  and  indirect  wholly  owned  subsidiary  of the
Company ("OEI  Louisiana"),  and a consortium of banks,  including Chase Bank of
Texas, National Association,  as Administrative Agent, and Morgan Guaranty Trust
Company of New York, as Syndication Agent (the "Revolving Credit Facility"). The
Revolving Credit Facility provides for an initial borrowing base of $600,000,000
and for the  guaranty by the Company of OEI  Louisiana's  obligations  under the
Revolving Credit  Facility.  The Company and OEI Louisiana plan to use the funds
available under the Revolving  Credit Facility in order to finance,  among other
things,  (i) the repayment of existing  senior credit  facilities of the Company
and UMC Petroleum  Corporation,  predecessor  by merger to OEI  Louisiana,  (ii)
future  exploration,  development and production  costs, and (iii) other working
capital needs.

         Additionally,  on March 27, 1998, UMC Resources Canada, Ltd., a British
Columbia corporation and wholly-owned,  indirect subsidiary of the Company ("UMC
Canada"),  entered into a  subfacility  with certain  lenders for  borrowings in
Canadian Dollars up to CDN $25,000,000  (subject to borrowing base  limitations)
(the "Canadian Subfacility"). The Canadian Subfacility provides for the guaranty
by the Company of UMC Canada's obligations under the Canadian Subfacility.

         The Company executed a Third Supplemental Indenture,  dated as of March
27, 1998,  by and among the  Company,  OEI  Louisiana  and State Street Bank and
Trust Company,  as successor in interest to Fleet National Bank, as trustee (the
"Trustee"),   relating  to  the  13  1/2%  Senior  Notes  due  2004  (the  "1994
Supplemental  Indenture").  The 1994 Supplemental  Indenture amends the original
indenture, dated as of December 1, 1994, by and among the Company, OEI Louisiana
and the Trustee,  as supplemented by the First  Supplemental  Indenture thereto,
dated as of September 19, 1996, and the Second  Supplemental  Indenture thereto,
dated as of July 14, 1997 (the "1994 Indenture").

         The Company  also  executed  on March 27,  1998,  a First  Supplemental
Indenture, by and among the Company, OEI Louisiana and the Trustee,  relating to
the  9  3/4%  Senior   Subordinated  Notes  due  2006  (the  "1996  Supplemental
Indenture"),  which amends the  original  indenture,  dated as of September  26,
1996,  by and among the  Company,  OEI  Louisiana  and the  Trustee  (the  "1996
Indenture").

         Additionally,   on  March  27,  1998,  the  Company  executed  a  First
Supplemental Indenture, by and among the Company, OEI Louisiana and the Trustee,
with  respect  to the  87/8%  Senior  Subordinated  Notes  due 2007  (the  "1997
Supplemental Indenture"),  amending the original indenture,  dated as of July 2,
1997, among the Company, OEI Louisiana and the Trustee (the "1997 Indenture").

         The 1994 Supplemental  Indenture,  the 1996 Supplemental  Indenture and

                                                                    Exhibit 10.1
                         EMPLOYMENT AGREEMENT

         This Employment Agreement ("Agreement") is entered into effective as of
March 27, 1998 (the  "Effective  Date") by and between  Ocean  Energy,  Inc.,  a
Delaware corporation ("Company"), and John B. Brock ("Employee").

         WHEREAS,  the Company  employs  Employee  and desires to continue  such
employment relationship and Employee desires to continue such employment;

         NOW,   THEREFORE,   in   consideration   of   the   mutual   covenants,
representations,  warranties,  and agreements  contained  herein,  and for other
valuable   consideration,   the  receipt  and   adequacy  of  which  are  hereby
acknowledged, the parties agree as follows:

         1. Employment. The Company hereby employs Employee, and Employee hereby
accepts employment by the Company, on the terms and conditions set forth in this
Agreement.

         2.  Term  of   Employment.   Subject  to  the  provisions  for  earlier
termination  provided in the Agreement,  the term of this Agreement (the "Term")
shall  commence  on  the  Effective  Date  and  shall  terminate  on  the  third
anniversary  of  the  Effective  Date;  provided,  however,  commencing  on  the
Effective  Date and on each day  thereafter,  the Term  shall  automatically  be
extended  one  additional  day unless the Board of Directors of the Company (the
"Board")  shall give written  notice to Employee that the Term shall cease to be
so extended as of a specified  future date, in which event the  Agreement  shall
terminate on the third anniversary of the specified future date. Notwithstanding
any provision of this  Agreement to the contrary,  termination of this Agreement
shall not alter or impair any rights or  benefits  of  Employee  (or  Employee's
estate or  beneficiaries)  that have arisen under this  Agreement on or prior to
such termination.

         3.  Employee's  Duties.  During  the Term,  Employee  shall  assume and
discharge  the  responsibilities  of the Chairman of the Board,  as well as such
other  responsibilities  as may be assigned to him by the Board;  provided  that
such duties are at all times consistent with the duties of such positions.

         Employee  agrees to devote his full  attention  and time during  normal
business  hours to the business and affairs of the Company and to use reasonable
best   efforts  to  perform   faithfully   and   efficiently   such  duties  and
responsibilities.  Notwithstanding the foregoing,  during the Term, Employee may
engage  in the  following  activities  so long as they do not  interfere  in any
material respect with the performance of Employee's duties and  responsibilities
hereunder:  (i) serve on corporate,  civic or charitable  boards or  committees,
(ii) deliver  lectures,  fulfill  speaking  engagements  or teach on a part-time
basis at educational  institutions,  and (iii) manage his personal  investments;
provided,  however,  in no event shall the conduct of any of such  activities by
Employee be deemed to materially  interfere  with  Employee's  duties  hereunder
until  Employee  has been  notified in writing  thereof by the Board and given a
reasonable period in which to cure such interference.

                  The Company agrees to use its reasonable best efforts to cause
Employee  to be  elected or  appointed,  or  re-elected  or  re-appointed,  as a
director of the Company at all times during the Term.

         4. Base  Compensation.  For  services  rendered by Employee  under this
Agreement the Company shall pay to Employee a base salary ("Base  Compensation")
of $475,000 per annum payable in accordance with the Company's customary payroll
practice  for its senior  executive  officers.  The amount of Base  Compensation
shall be reviewed  periodically  by the Board and may be increased  from time to
time as the Board may deem appropriate.  Base Compensation,  as in effect at any
time, may not be decreased.

         5. Annual Bonus. In addition to his Base  Compensation,  Employee shall
be eligible to receive each year during the Term, a cash incentive payment in an
amount equal to 200% of Employee's Base Compensation  (the "Target Bonus").  The
amount of the  Target  Bonus  earned  for any year  shall be  determined  by the
Compensation  Committee of the Board based on Employee's individual  performance
and the performance by the Company.

         6. Other  Benefits.  Employee  shall be entitled to  participate in all
incentive  compensation plans and to receive all fringe benefits and perquisites
offered  by the  Company  to any of its senior  executive  officers,  including,
without  limitation,  participation  in the various  employee  benefit  plans or
programs  provided to the  employees  of the Company in general,  subject to the
regular  eligibility  requirements with respect to each of such benefit plans or
programs,  and such other  benefits or  prerequisites  as may be approved by the
Board  during the Term,  all on a basis at least as favorable to Employee as may
be provided or offered to any other senior executive officer of the Company.

         7.  Termination.  This Agreement may be terminated  prior to the end of
its Term as set
forth below.

                  (a) Resignation. Employee may resign his position at any time.
         In the event of such resignation, except in the case of resignation for
         Good  Reason (as  defined  below),  Employee  shall not be  entitled to
         further compensation pursuant to this Agreement.

                  (b) Death.  If Employee's  employment is terminated due to his
         death,  this  Agreement  shall  terminate and the Company shall have no
         obligations to his legal representatives with respect to this Agreement
         other than the payment of any compensation  which had accrued hereunder
         at the date of Employee's death.

                  (c)      Discharge.

                           (i) The  Company may  terminate  this  Agreement  and
                  Employee's  employment for any reason deemed sufficient by the
                  Company upon notice as provided in Section 10. However, in the
                  event that Employee's employment is terminated during the Term
                  by the Company  for any reason  other than his  Misconduct  or
                  Disability (as such terms are defined below), then, subject to
                  Section 7(h) below:  (A) within five business days of the Date
                  of  Termination,  the Company shall pay to Employee a lump sum
                  amount in cash equal to three times the sum of (1)  Employee's
                  Base Compensation and (2) Employee's Target Bonus; (B) for the
                  36- month period after such Date of  Termination  the Company,
                  at its sole expense,  shall  continue to provide or arrange to
                  provide  Employee  (and  Employee's  dependents)  with  health
                  insurance  benefits  no less  favorable  than the health  plan
                  benefits  provided by the Company  (or any  successor)  during
                  such 36-month  period to any senior  executive  officer of the
                  Company;  provided,  further,  to the extent the  coverage  or
                  benefits  received are taxable to Employee,  the Company shall
                  make Employee "whole" on a net after tax basis; and (C) on the
                  Date of Termination all then outstanding  Company  stock-based
                  awards of Employee,  whether under this  Agreement,  a Company
                  stock plan or otherwise,  shall become immediately exercisable
                  and payable in full, as the case may be, with any  performance
                  goals associated  therewith being deemed to have been achieved
                  at  the  maximum  levels.  Notwithstanding  anything  in  this
                  Agreement  to the  contrary,  if any  payment to  Employee  in
                  respect of a Company  stock-based  award  would give rise to a
                  short-swing  profit  liability to Employee under Section 16(b)
                  of the Securities  Exchange Act of 1934, then both the payment
                  and the entitlement to payment thereof shall  automatically be
                  deferred  until the earliest date at which the payment of such
                  benefit would not result in a short-swing  profit liability to
                  Employee.

                           (ii) Notwithstanding the foregoing provisions of this
                  Section  7, in the event  Employee  is  terminated  because of
                  Misconduct,  the Company shall have no obligations pursuant to
                  this Agreement after the Date of Termination.  As used herein,
                  "Misconduct"  means (a) the willful and  continued  failure by
                  Employee to substantially  perform his duties with the Company
                  (other  than  any  such  failure   resulting  from  Employee's
                  incapacity  due to  physical  or  mental  illness  or any such
                  actual or  anticipated  failure after the issuance of a Notice
                  of Termination  by Employee for Good Reason),  after a written
                  demand for substantial performance is delivered to Employee by
                  the Board, which demand specifically  identifies the manner in
                  which the Board  believes that Employee has not  substantially
                  performed his duties,  or (b) the willful engaging by Employee
                  in conduct which is demonstrably  and materially  injurious to
                  the Company,  monetarily or otherwise. For purposes hereof, no
                  act,  or failure to act,  on  Employee's  part shall be deemed
                  "willful"  unless done, or omitted to be done, by Employee not
                  in good faith and without  reasonable  belief that  Employee's
                  action or omission was in the best interest of the Company.

<PAGE>



                  Notwithstanding the foregoing, Employee shall not be deemed to
                  have been  terminated  for  Misconduct  unless and until there
                  shall have been  delivered  to Employee a copy of a resolution
                  duly  adopted  by  the  affirmative  vote  of  not  less  than
                  two-thirds of the entire  membership of the Board at a meeting
                  of the Board called and held for such purpose, finding that in
                  the good  faith  opinion of the Board  Employee  was guilty of
                  conduct set forth above and specifying the particulars thereof
                  in detail.

         (d)      Disability.

                           (i) If  Employee  shall  have  been  absent  from the
                  full-time  performance  of Employee's  duties with the Company
                  for  six   consecutive   months  as  a  result  of  Employee's
                  incapacity due to physical or mental illness, as determined by
                  Employee's physician,  and within 30 days after written Notice
                  of Termination is given by the Company Employee shall not have
                  returned to the full-time  performance  of Employee's  duties,
                  Employee's  employment  may be  terminated  by the Company for
                  "Disability",  provided  Employee is entitled to and receiving
                  benefits  under an insured  long term  disability  plan of the
                  Company. Thereafter, Employee shall not be entitled to further
                  compensation pursuant to this Agreement.

                           (ii) If Employee  fails during any period  during the
                  Term to perform  Employee's  full-time duties with the Company
                  as a result of incapacity  due to physical or mental  illness,
                  as determined by Employee's physician, Employee shall continue
                  to receive his Base  Compensation,  less any amount payable to
                  Employee  under a  Company  disability  plan,  and  all  other
                  compensation  and  benefits  during  such  period  until  this
                  Agreement is terminated.

                  (e) Resignation for Good Reason. Employee shall be entitled to
         terminate his employment for Good Reason as defined herein. If Employee
         terminates his  employment for Good Reason,  Employee shall be entitled
         to the compensation and benefits  provided in Paragraph 7(c)(i) hereof.
         "Good  Reason"  shall  mean  (1)  the  breach  of any of the  Company's
         obligations  under this Agreement  without  Employee's  express written
         consent or (2) the occurrence of any of the following circumstances, as
         the case may be, without Employee's express written consent unless such
         breach  or  circumstances  are  fully  corrected  prior  to the Date of
         Termination   specified  in  the  Notice  of  Termination  pursuant  to
         Subsection 7(f) given in respect thereof:

                           (i) the  assignment  by the Board to  Employee of any
                  duties  that,  in the good  faith  opinion  of  Employee,  are
                  inconsistent with Employee's positions with the Company, or an
                  adverse  alteration  (as determined in good faith by Employee)
                  in  the  nature  or  status  of  Employee's   office,   title,
                  responsibilities, including reporting responsibilities, or the
                  conditions  of  Employee's  employment  from  those in  effect
                  immediately prior to such alteration;

                                           -4-

<PAGE>



                           (ii) the failure by the Company to continue in effect
                  any compensation  plan in which Employee  participates that is
                  material to Employee's total compensation  unless an equitable
                  arrangement  (embodied in an ongoing substitute or alternative
                  plan) has been made with respect to such plan,  or the failure
                  by the Company to continue  Employee's  participation  therein
                  (or in such  substitute  or  alternative  plan) on a basis not
                  materially  less  favorable to Employee,  both in terms of the
                  amount  of  benefits  provided  and the  level  of  Employee's
                  participation relative to other participants;

                           (iii) the taking of any action by the  Company  which
                  would  directly  or  indirectly  materially  reduce or deprive
                  Employee  of any  material  fringe  benefit  then  enjoyed  by
                  Employee;

                           (iv)  the   failure  of  the   Company  to  obtain  a
                  satisfactory  agreement from any successor to assume and agree
                  to  perform  this  Agreement,  as  contemplated  in Section 12
                  hereof;

                           (v)  the   relocation  of  the  Company's   principal
                  executive   offices   outside  the  greater   Houston,   Texas
                  metropolitan  area,  or the  Company's  requiring  Employee to
                  relocate  anywhere  other than the  location of the  Company's
                  principal executive offices, except for required travel on the
                  Company's business to an extent substantially  consistent with
                  Employee's past business travel obligations; or

                           (vi)  any   purported   termination   of   Employee's
                  employment  that  is not  effected  pursuant  to a  Notice  of
                  Termination  satisfying  the  requirements  of Subsection  (f)
                  hereof, which purported termination shall not be effective for
                  purposes of this Agreement.

                  Employee's  right to  terminate  employment  pursuant  to this
         subsection  shall  not be  affected  by  Employee's  incapacity  due to
         physical  or  mental  illness.   In  addition,   Employee's   continued
         employment  following  any event,  act or omission,  regardless  of the
         length of such continued  employment,  shall not constitute  Employee's
         consent  to, or a waiver of  Employee's  rights  with  respect to, such
         event,  act  or  omission   constituting  a  Good  Reason  circumstance
         hereunder.

                  (f)  Notice  of  Termination.  Any  purported  termination  of
         Employee's   employment  by  the  Company  or  by  Employee   shall  be
         communicated by written Notice of Termination to the other party hereto
         in accordance with Section 10 hereof. For purposes of this Agreement, a
         "Notice of  Termination"  shall mean a notice  which shall set forth in
         reasonable detail the reason for termination of Employee's  employment,
         or in the case of resignation for Good Reason, said notice must specify
         in  reasonable  detail  the basis for such  resignation.  No  purported
         termination  which is not effected  pursuant to this Section 7(f) shall
         be effective.

                  (g) Date of Termination, Etc. "Date of Termination" shall mean
         the date  specified  in the Notice of  Termination.  Either  party may,
         within 15 days after any Notice of Termination is given, provide notice
         to the other party  pursuant to Section 10 hereof that a dispute exists
         concerning the  termination.  Notwithstanding  the pendency of any such
         dispute,  the  Company  will  continue  to pay  Employee  his full Base
         Compensation  in effect when the notice  giving rise to the dispute was
         given (including,  but not limited to, Base  Compensation) and continue
         Employee as a participant  in all  compensation,  benefit and insurance
         plans in which Employee was  participating  when the notice giving rise
         to the  dispute  was given,  until the  dispute is finally  resolved in
         accordance with Section 16 hereof,  but in no event past the expiration
         date of this Agreement.  Any payments and benefits provided during such
         period of dispute  shall not reduce any other  payments or benefits due
         Employee under this Agreement nor shall Employee be liable to repay the
         Company for such payments and benefits if it is finally  determined the
         Employee is not entitled to payments under the other provisions of this
         Agreement following Employee's termination of employment.

                  (h) Mitigation. Employee shall not be required to mitigate the
         amount of any  payment or  benefit  provided  for in this  Section 7 by
         seeking  other  employment  or  otherwise,  nor shall the amount of any
         payment or benefit  provided  for in this  Agreement  be reduced by any
         compensation or benefit earned by Employee as a result of employment by
         another employer,  self-employment earnings, by retirement benefits, by
         offset  against  any  amount  claimed  to be owing by  Employee  to the
         Company, or otherwise, except that any cash severance amount payable to
         Employee pursuant to a Company maintained  severance plan or policy for
         employees  in general  shall  reduce the  amount  otherwise  payable to
         Employee pursuant to Section 7(c)(i)(A).

                  (i) Gross-Up of Parachute  Payments.  If, during the Term, any
         payment,  including  without  limitation  any imputed  income,  made or
         benefit provided to or on behalf of Employee, including any accelerated
         vesting or any deferred compensation or other award, in connection with
         a "change in control" of the  Company,  whether or not made or provided
         pursuant to this  Agreement,  results in Employee  being subject to the
         excise tax  imposed by section  4999 of the  Internal  Revenue  Code of
         1986, as amended (or any successor or similar  provision),  the Company
         shall pay  Employee  an  additional  amount  of cash  (the  "Additional
         Amount") such that the net amount of all payments and benefits received
         by Employee  after paying all applicable  taxes  thereon,  including on
         such Additional  Amount,  shall be equal to the net after-tax amount of
         payments and benefits that Employee would have received if section 4999
         were not applicable.

         8.  Non-exclusivity of Rights.  Nothing in this Agreement shall prevent
or limit Employee's  continuing or future  participation in any benefit,  bonus,
incentive  or  other  plan or  program  provided  by the  Company  or any of its
affiliated  companies  and for which  Employee may qualify,  nor shall  anything
herein limit or otherwise adversely affect such rights as Employee may


                                       -6-

<PAGE>



have under any stock option or other  agreements  with the Company or any of its
affiliated companies.

         9.  Assignability.  The obligations of Employee  hereunder are personal
and may  not be  assigned  or  delegated  by him or  transferred  in any  manner
whatsoever,   nor  are  such  obligations  subject  to  involuntary  alienation,
assignment  or  transfer.  The  Company  shall  have the  right to  assign  this
Agreement and to delegate all rights, duties and obligations  hereunder,  either
in  whole  or in  part,  to  any  parent,  affiliate,  successor  or  subsidiary
organization  or company of the Company,  provided  that no such  assignment  or
delegation shall relieve the Company of its duties and obligations hereunder nor
affect the rights of Employee hereunder.

         10. Notice.  For the purpose of this  Agreement,  notices and all other
communications  provided for in the  Agreement  shall be in writing and shall be
deemed to have been duly  given when  personally  delivered,  sent by  overnight
courier or by facsimile  with  confirmation  of receipt or on the third business
day  after  being  mailed by  United  States  registered  mail,  return  receipt
requested,  postage  prepaid,  addressed to the Company at its principal  office
address and facsimile number, directed to the attention of the Board with a copy
to the Secretary of the Company, and to Employee at Employee's residence address
and  facsimile  number on the records of the Company or to such other address as
either party may have  furnished to the other in writing in accordance  herewith
except that notice of change of address shall be effective only upon receipt.

         11. Validity.  The invalidity or  unenforceability  of any provision of
this  Agreement  shall not affect the  validity or  enforceability  of any other
provision of this Agreement, which shall remain in full force and effect.

         12.      Successors; Binding Agreement.

         (a) The Company will require any successor (whether direct or indirect,
by purchase, merger,  consolidation or otherwise) to all or substantially all of
the business and assets of the Company  ("Successor")  or any corporation  which
becomes the ultimate  parent  corporation  of the Company or any such  Successor
("Ultimate Parent") to expressly assume and agree in writing satisfactory to the
Employee  to perform  this  Agreement  in the same manner and to the same extent
that the Company would be required to perform it if no such succession had taken
place.  Failure of the Company to obtain  such  written  agreement  prior to the
effectiveness  of any such  succession  or  creation  of the parent  corporation
relationship  shall be a breach of this Agreement and shall entitle  Employee to
compensation  and  benefits  from the Company in the same amount and on the same
terms as he would be entitled to hereunder if he terminated  his  employment for
Good Reason, except that for purposes of implementing the foregoing, the date on
which any such succession (or creation of the parent  corporation  relationship)
becomes  effective  shall be  deemed  the Date of  Termination.  As used in this
Agreement, including, without limitation, in Section 3, the term "Company" shall
include any  Successor  and  Ultimate  Parent  which  executes  and delivers the
Agreement as provided for in this Section 12 or which otherwise becomes bound by
all terms and provisions of this Agreement by operation of law.

         (b) This Agreement and all rights of Employee  hereunder shall inure to
the   benefit  of  and  be   enforceable   by   Employee's   personal  or  legal
representatives,  executors,  administrators,  successors,  heirs, distributees,
devisees and legatees.

         13.  Indemnification.  During  the Term and for a period  of six  years
thereafter,  the Company  shall cause  Employee to be covered by and named as an
insured  under any policy or contract of insurance  obtained by it to insure its
directors  and  officers  against  personal  liability  for acts or omissions in
connection  with  service as an officer or director of the Company or service in
other  capacities  at the  request of the  Company.  The  coverage  provided  to
Employee  pursuant  to this  Section  8 shall  be of a scope  and on  terms  and
conditions at least as favorable as the most favorable  coverage provided to any
other officer or director of the Company (or any successor).

                  In addition,  to the maximum extent permitted under applicable
law, during the Term and for a period of six years thereafter, the Company shall
indemnify   Employee  against  and  hold  Employee   harmless  from  any  costs,
liabilities,  losses and  exposures  for  Employee's  services  as an  employee,
officer and director of the Company (or any successor).

         14.  Miscellaneous.  No  provision of this  Agreement  may be modified,
waived or discharged unless such waiver,  modification or discharge is agreed to
in  writing  and signed by  Employee  and such  officer  as may be  specifically
authorized  by the Board.  No waiver by either  party  hereto at any time of any
breach by the other party hereto of, or in  compliance  with,  any  condition or
provision of this  Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or  subsequent  time.  This  Agreement  is an  integration  of the parties
agreement;  no  agreement  or  representations,  oral or  otherwise,  express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Texas.

         15.  Counterparts.  This  Agreement  may be  executed  in  one or  more
counterparts,  each of which shall be deemed to be an original  but all of which
together will constitute one and the same instrument.

         16.  Arbitration.  Employee  shall be permitted  (but not  required) to
elect that any dispute or controversy  arising under or in connection  with this
Agreement be settled by  arbitration  in the city in which  Employee  resides at
such time in accordance with the rules of the American  Arbitration  Association
then in effect.  Judgment may be entered on the arbitrator's  award in any court
having jurisdiction. All legal fees and costs incurred by Employee in connection
with the  resolution of any dispute or controversy  under or in connection  with
this  Agreement  shall be paid by the  Company  as bills for such  services  are
presented by Employee to the Company.

         17. Prior Employment Agreement.  This Agreement supersedes and replaces
in full any existing employment agreement (written or oral) between the parties.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement ("Agreement") is entered into effective as of
March 27, 1998 (the  "Effective  Date") by and between  Ocean  Energy,  Inc.,  a
Delaware corporation ("Company"), and James C. Flores ("Employee").

         WHEREAS,  the Company  employs  Employee  and desires to continue  such
employment relationship and Employee desires to continue such employment;

         NOW,   THEREFORE,   in   consideration   of   the   mutual   covenants,
representations,  warranties,  and agreements  contained  herein,  and for other
valuable   consideration,   the  receipt  and   adequacy  of  which  are  hereby
acknowledged, the parties agree as follows:

         1. Employment. The Company hereby employs Employee, and Employee hereby
accepts employment by the Company, on the terms and conditions set forth in this
Agreement.

         2.  Term  of   Employment.   Subject  to  the  provisions  for  earlier
termination  provided in the Agreement,  the term of this Agreement (the "Term")
shall  commence  on  the  Effective  Date  and  shall  terminate  on  the  third
anniversary  of  the  Effective  Date;  provided,  however,  commencing  on  the
Effective  Date and on each day  thereafter,  the Term  shall  automatically  be
extended  one  additional  day unless the Board of Directors of the Company (the
"Board")  shall give written  notice to Employee that the Term shall cease to be
so extended as of a specified  future date, in which event the  Agreement  shall
terminate on the third anniversary of the specified future date. Notwithstanding
any provision of this  Agreement to the contrary,  termination of this Agreement
shall not alter or impair any rights or  benefits  of  Employee  (or  Employee's
estate or  beneficiaries)  that have arisen under this  Agreement on or prior to
such termination.

         3.  Employee's  Duties.  During the Term,  Employee  shall serve as the
Chief Executive Officer and President of the Company, with such customary duties
and  responsibilities  as may from time to time be assigned to him by the Board,
provided  that such duties are at all times  consistent  with the duties of such
positions.  Employee shall report directly to the Board.  All other employees of
the Company shall report to Employee.

         Employee  agrees to devote his full  attention  and time during  normal
business  hours to the business and affairs of the Company and to use reasonable
best   efforts  to  perform   faithfully   and   efficiently   such  duties  and
responsibilities.  Notwithstanding  the foregoing,  during the Term Employee may
engage  in the  following  activities  so long as they do not  interfere  in any
material respect with the performance of Employee's duties and  responsibilities
hereunder:  (i) serve on corporate,  civic or charitable  boards or  committees,
(ii) deliver  lectures,  fulfill  speaking  engagements  or teach on a part-time
basis at educational  institutions,  and (iii) manage his personal  investments;
provided,  however,  in no event shall the conduct of any of such  activities by
Employee be deemed to materially  interfere  with  Employee's  duties  hereunder
until  Employee  has been  notified in writing  thereof by the Board and given a
reasonable period in which to cure such interference.

                  The Company agrees to use its reasonable best efforts to cause
Employee  to be  elected or  appointed,  or  re-elected  or  re-appointed,  as a
director of the Company at all times during the Term.

         4. Base  Compensation.  For  services  rendered by Employee  under this
Agreement the Company shall pay to Employee a base salary ("Base  Compensation")
of $600,000 per annum payable in accordance with the Company's customary payroll
practice  for its senior  executive  officers.  The amount of Base  Compensation
shall be reviewed  periodically  by the Board and may be increased  from time to
time as the Board may deem appropriate.  Base Compensation,  as in effect at any
time, may not be decreased.

         5. Annual Bonus. In addition to his Base  Compensation,  Employee shall
be eligible to receive each year during the Term, a cash incentive payment in an
amount equal to 200% of Employee's Base Compensation  (the "Target Bonus").  The
amount of the  Target  Bonus  earned  for any year  shall be  determined  by the
Compensation  Committee of the Board based on Employee's individual  performance
and the performance by the Company.

         6. Other  Benefits.  Employee  shall be entitled to  participate in all
incentive  compensation plans and to receive all fringe benefits and perquisites
offered  by the  Company  to any of its senior  executive  officers,  including,
without  limitation,  participation  in the various  employee  benefit  plans or
programs  provided to the  employees  of the Company in general,  subject to the
regular  eligibility  requirements with respect to each of such benefit plans or
programs,  and such other  benefits or  prerequisites  as may be approved by the
Board  during the Term,  all on a basis at least as favorable to Employee as may
be provided or offered to any other senior executive officer of the Company.

                  In addition, and not in limitation of the foregoing,  Employee
shall be entitled to the following:

                  (a) Business  Expenses.  The Company shall reimburse  Employee
         for all  business  expenses  reasonably  incurred  by  Employee  in the
         performance of his duties. It is understood that Employee is authorized
         to incur reasonable business expenses for promoting the business of the
         Company,  including reasonable  expenditures for travel, lodging, meals
         and  client  or   business   associate   entertainment.   Request   for
         reimbursement  for such expenses  must be  accompanied  by  appropriate
         documentation.

                  (b) Automobile. The Company shall either provide Employee with
         an  automobile  of a make and model  selected  by  Employee or promptly
         reimburse  Employee  in full for his cost of leasing or  purchasing  an
         automobile.  In addition,  the Company shall pay or reimburse  Employee
         for  all  reasonable  costs  and  expenses  associated  with  the  use,
         maintenance, insurance and repair of such automobile.

<PAGE>



                  (c) Clubs.  The Company shall reimburse  Employee for the cost
         and expenses (including  initiation fees,  assessments and annual dues)
         of such social clubs and business clubs as Employee determines,  in his
         good faith opinion,  to be helpful or appropriate to the performance of
         his duties.

                  (d)  Relocation  Expenses.   In  conjunction  with  Employee's
         relocation of his  principal  residence to the greater  Houston,  Texas
         metropolitan  area,  the  Company  shall  reimburse  Employee  for  all
         out-of-pocket  expenses  involved  in  such  move,  including,  without
         limitation,  packing and transport of personal,  family,  and household
         goods and vehicles by suitable  service  providers,  for any  brokerage
         fees  for the  sale  or  purchase  of any  residences,  of any  loss of
         economic  value  occasioned  by the timing of the sale or by Employee's
         inability to recover monies  invested in any personal  residence  sold,
         temporary housing costs in suitable  alternative  housing,  all utility
         severance and hook-up costs,  and any other  relocation  expenses,  all
         such sums to be  grossed-up  for the  impact of any  federal,  state or
         local  taxes  levied  against   Employee  for  such  portions  of  such
         reimbursement as shall be taxable and non-deductible to Employee.

         7.  Termination.  This Agreement may be terminated  prior to the end of
its Term as set forth below. (a)  Resignation.  Employee may resign his position
at any time.

         In the event of such resignation, except in the case of resignation for
         Good  Reason (as  defined  below),  Employee  shall not be  entitled to
         further compensation pursuant to this Agreement.

                  (b) Death.  If Employee's  employment is terminated due to his
         death,  this  Agreement  shall  terminate and the Company shall have no
         obligations to his legal representatives with respect to this Agreement
         other than the payment of any compensation  which had accrued hereunder
         at the date of Employee's death.

                  (c)      Discharge.

                           (i) The  Company may  terminate  this  Agreement  and
                  Employee's  employment for any reason deemed sufficient by the
                  Company upon notice as provided in Section 10. However, in the
                  event that Employee's employment is terminated during the Term
                  by the Company  for any reason  other than his  Misconduct  or
                  Disability (as such terms are defined below), then, subject to
                  Section 7(h) below:  (A) within five business days of the Date
                  of  Termination,  the Company shall pay to Employee a lump sum
                  amount in cash equal to three times the sum of (1)  Employee's
                  Base Compensation and (2) Employee's Target Bonus; (B) for the
                  36- month period after such Date of  Termination  the Company,
                  at its sole expense,  shall  continue to provide or arrange to
                  provide  Employee  (and  Employee's  dependents)  with  health
                  insurance  benefits  no less  favorable  than the health  plan
                  benefits  provided by the Company  (or any  successor)  during
                  such 36-month period to any senior

                  executive officer of the Company;  provided,  further,  to the
                  extent  the  coverage  or  benefits  received  are  taxable to
                  Employee,  the Company  shall make  Employee  "whole" on a net
                  after tax basis;  and (C) on the Date of Termination  all then
                  outstanding  Company  stock-based awards of Employee,  whether
                  under this Agreement, a Company stock plan or otherwise, shall
                  become  immediately  exercisable  and payable in full,  as the
                  case may be, with any performance  goals associated  therewith
                  being  deemed to have been  achieved  at the  maximum  levels.
                  Notwithstanding anything in this Agreement to the contrary, if
                  any payment to  Employee  in respect of a Company  stock-based
                  award would give rise to a  short-swing  profit  liability  to
                  Employee under Section 16(b) of the Securities Exchange Act of
                  1934,  then both the  payment and the  entitlement  to payment
                  thereof  shall  automatically  be deferred  until the earliest
                  date at which the payment of such benefit  would not result in
                  a short-swing profit liability to Employee.

                           (ii) Notwithstanding the foregoing provisions of this
                  Section  7, in the event  Employee  is  terminated  because of
                  Misconduct,  the Company shall have no obligations pursuant to
                  this Agreement after the Date of Termination.  As used herein,
                  "Misconduct"  means (a) the willful and  continued  failure by
                  Employee to substantially  perform his duties with the Company
                  (other  than  any  such  failure   resulting  from  Employee's
                  incapacity  due to  physical  or  mental  illness  or any such
                  actual or  anticipated  failure after the issuance of a Notice
                  of Termination  by Employee for Good Reason),  after a written
                  demand for substantial performance is delivered to Employee by
                  the Board, which demand specifically  identifies the manner in
                  which the Board  believes that Employee has not  substantially
                  performed his duties,  or (b) the willful engaging by Employee
                  in conduct which is demonstrably  and materially  injurious to
                  the Company,  monetarily or otherwise. For purposes hereof, no
                  act,  or failure to act,  on  Employee's  part shall be deemed
                  "willful"  unless done, or omitted to be done, by Employee not
                  in good faith and without  reasonable  belief that  Employee's
                  action or omission  was in the best  interest of the  Company.
                  Notwithstanding the foregoing, Employee shall not be deemed to
                  have been  terminated  for  Misconduct  unless and until there
                  shall have been  delivered  to Employee a copy of a resolution
                  duly  adopted  by  the  affirmative  vote  of  not  less  than
                  two-thirds of the entire  membership of the Board at a meeting
                  of the Board called and held for such purpose, finding that in
                  the good  faith  opinion of the Board  Employee  was guilty of
                  conduct set forth above and specifying the particulars thereof
                  in detail.

         (d)      Disability.

                           (i) If  Employee  shall  have  been  absent  from the
                  full-time  performance  of Employee's  duties with the Company
                  for  six   consecutive   months  as  a  result  of  Employee's
                  incapacity due to physical or mental illness, as determined by
                  Employee's physician,  and within 30 days after written Notice
                  of Termination is


                                       -4-

<PAGE>



                  given by the Company  Employee  shall not have returned to the
                  full-time   performance  of  Employee's   duties,   Employee's
                  employment may be terminated by the Company for  "Disability",
                  provided Employee is entitled to and receiving  benefits under
                  an  insured  long  term   disability   plan  of  the  Company.
                  Thereafter,   Employee   shall  not  be  entitled  to  further
                  compensation pursuant to this Agreement.

                           (ii) If Employee  fails during any period  during the
                  Term to perform  Employee's  full-time duties with the Company
                  as a result of incapacity  due to physical or mental  illness,
                  as determined by Employee's physician, Employee shall continue
                  to receive his Base  Compensation,  less any amount payable to
                  Employee  under a  Company  disability  plan,  and  all  other
                  compensation  and  benefits  during  such  period  until  this
                  Agreement is terminated.

                  (e) Resignation for Good Reason. Employee shall be entitled to
         terminate his employment for Good Reason as defined herein. If Employee
         terminates his  employment for Good Reason,  Employee shall be entitled
         to the compensation and benefits  provided in Paragraph 7(c)(i) hereof.
         "Good  Reason"  shall  mean  (1)  the  breach  of any of the  Company's
         obligations  under this Agreement  without  Employee's  express written
         consent or (2) the occurrence of any of the following circumstances, as
         the case may be, without Employee's express written consent unless such
         breach  or  circumstances  are  fully  corrected  prior  to the Date of
         Termination   specified  in  the  Notice  of  Termination  pursuant  to
         Subsection 7(f) given in respect thereof:

                           (i) the  assignment  by the Board to  Employee of any
                  duties  that,  in the good  faith  opinion  of  Employee,  are
                  inconsistent with Employee's positions with the Company, or an
                  adverse  alteration  (as determined in good faith by Employee)
                  in  the  nature  or  status  of  Employee's   office,   title,
                  responsibilities, including reporting responsibilities, or the
                  conditions  of  Employee's  employment  from  those in  effect
                  immediately prior to such alteration;

                           (ii) the failure by the Company to continue in effect
                  any compensation  plan in which Employee  participates that is
                  material to Employee's total compensation  unless an equitable
                  arrangement  (embodied in an ongoing substitute or alternative
                  plan) has been made with respect to such plan,  or the failure
                  by the Company to continue  Employee's  participation  therein
                  (or in such  substitute  or  alternative  plan) on a basis not
                  materially  less  favorable to Employee,  both in terms of the
                  amount  of  benefits  provided  and the  level  of  Employee's
                  participation relative to other participants;

                           (iii) the taking of any action by the  Company  which
                  would  directly  or  indirectly  materially  reduce or deprive
                  Employee  of any  material  fringe  benefit  then  enjoyed  by
                  Employee;

                           (iv)  the   failure  of  the   Company  to  obtain  a
                  satisfactory  agreement from any successor to assume and agree
                  to  perform  this  Agreement,  as  contemplated  in Section 12
                  hereof;

                           (v)  the   relocation  of  the  Company's   principal
                  executive   offices   outside  the  greater   Houston,   Texas
                  metropolitan  area,  or the  Company's  requiring  Employee to
                  relocate  anywhere  other than the  location of the  Company's
                  principal executive offices, except for required travel on the
                  Company's business to an extent substantially  consistent with
                  Employee's past business travel obligations; or

                           (vi)  any   purported   termination   of   Employee's
                  employment  that  is not  effected  pursuant  to a  Notice  of
                  Termination  satisfying  the  requirements  of Subsection  (f)
                  hereof, which purported termination shall not be effective for
                  purposes of this Agreement.

                  Employee's  right to  terminate  employment  pursuant  to this
         subsection  shall  not be  affected  by  Employee's  incapacity  due to
         physical  or  mental  illness.   In  addition,   Employee's   continued
         employment  following  any event,  act or omission,  regardless  of the
         length of such continued  employment,  shall not constitute  Employee's
         consent  to, or a waiver of  Employee's  rights  with  respect to, such
         event,  act  or  omission   constituting  a  Good  Reason  circumstance
         hereunder.

                  (f)  Notice  of  Termination.  Any  purported  termination  of
         Employee's   employment  by  the  Company  or  by  Employee   shall  be
         communicated by written Notice of Termination to the other party hereto
         in accordance with Section 10 hereof. For purposes of this Agreement, a
         "Notice of  Termination"  shall mean a notice  which shall set forth in
         reasonable detail the reason for termination of Employee's  employment,
         or in the case of resignation for Good Reason, said notice must specify
         in  reasonable  detail  the basis for such  resignation.  No  purported
         termination  which is not effected  pursuant to this Section 7(f) shall
         be effective.

                  (g) Date of Termination, Etc. "Date of Termination" shall mean
         the date  specified  in the Notice of  Termination.  Either  party may,
         within 15 days after any Notice of Termination is given, provide notice
         to the other party  pursuant to Section 10 hereof that a dispute exists
         concerning the  termination.  Notwithstanding  the pendency of any such
         dispute,  the  Company  will  continue  to pay  Employee  his full Base
         Compensation  in effect when the notice  giving rise to the dispute was
         given (including,  but not limited to, Base  Compensation) and continue
         Employee as a participant  in all  compensation,  benefit and insurance
         plans in which Employee was  participating  when the notice giving rise
         to the  dispute  was given,  until the  dispute is finally  resolved in
         accordance with Section 16 hereof,  but in no event past the expiration
         date of this Agreement.  Any payments and benefits provided during such
         period of dispute  shall not reduce any other  payments or benefits due
         Employee under this Agreement nor shall Employee be liable to repay the
         Company for such


                                       -6-

<PAGE>



         payments and benefits if it is finally  determined  the Employee is not
         entitled  to  payments  under the other  provisions  of this  Agreement
         following Employee's termination of employment.

                  (h) Mitigation. Employee shall not be required to mitigate the
         amount of any  payment or  benefit  provided  for in this  Section 7 by
         seeking  other  employment  or  otherwise,  nor shall the amount of any
         payment or benefit  provided  for in this  Agreement  be reduced by any
         compensation or benefit earned by Employee as a result of employment by
         another employer,  self-employment earnings, by retirement benefits, by
         offset  against  any  amount  claimed  to be owing by  Employee  to the
         Company, or otherwise, except that any cash severance amount payable to
         Employee pursuant to a Company maintained  severance plan or policy for
         employees  in general  shall  reduce the  amount  otherwise  payable to
         Employee pursuant to Section 7(c)(i)(A).

                  (i) Gross-Up of Parachute  Payments.  If, during the Term, any
         payment,  including  without  limitation  any imputed  income,  made or
         benefit provided to or on behalf of Employee, including any accelerated
         vesting or any deferred compensation or other award, in connection with
         a "change in control" of the  Company,  whether or not made or provided
         pursuant to this  Agreement,  results in Employee  being subject to the
         excise tax  imposed by section  4999 of the  Internal  Revenue  Code of
         1986, as amended (or any successor or similar  provision),  the Company
         shall pay  Employee  an  additional  amount  of cash  (the  "Additional
         Amount") such that the net amount of all payments and benefits received
         by Employee  after paying all applicable  taxes  thereon,  including on
         such Additional  Amount,  shall be equal to the net after-tax amount of
         payments and benefits that Employee would have received if section 4999
         were not applicable.

         8.  Non-exclusivity of Rights.  Nothing in this Agreement shall prevent
or limit Employee's  continuing or future  participation in any benefit,  bonus,
incentive  or  other  plan or  program  provided  by the  Company  or any of its
affiliated  companies  and for which  Employee may qualify,  nor shall  anything
herein  limit or  otherwise  adversely  affect such rights as Employee  may have
under  any stock  option  or other  agreements  with the  Company  or any of its
affiliated companies.

         9.  Assignability.  The obligations of Employee  hereunder are personal
and may  not be  assigned  or  delegated  by him or  transferred  in any  manner
whatsoever,   nor  are  such  obligations  subject  to  involuntary  alienation,
assignment  or  transfer.  The  Company  shall  have the  right to  assign  this
Agreement and to delegate all rights, duties and obligations  hereunder,  either
in  whole  or in  part,  to  any  parent,  affiliate,  successor  or  subsidiary
organization  or company of the Company,  provided  that no such  assignment  or
delegation shall relieve the Company of its duties and obligations hereunder nor
affect the rights of Employee hereunder.

         10. Notice.  For the purpose of this  Agreement,  notices and all other
communications  provided for in the  Agreement  shall be in writing and shall be
deemed to have been duly given when


                                       -7-

personally   delivered,   sent  by  overnight   courier  or  by  facsimile  with
confirmation  of  receipt or on the third  business  day after  being  mailed by
United States  registered  mail,  return  receipt  requested,  postage  prepaid,
addressed to the Company at its principal  office address and facsimile  number,
directed  to the  attention  of the Board  with a copy to the  Secretary  of the
Company, and to Employee at Employee's residence address and facsimile number on
the  records of the  Company or to such other  address as either  party may have
furnished to the other in writing in accordance  herewith  except that notice of
change of address shall be effective only upon receipt.

         11. Validity.  The invalidity or  unenforceability  of any provision of
this  Agreement  shall not affect the  validity or  enforceability  of any other
provision of this Agreement, which shall remain in full force and effect.

         12.      Successors; Binding Agreement.

         (a) The Company will require any successor (whether direct or indirect,
by purchase, merger,  consolidation or otherwise) to all or substantially all of
the business and assets of the Company  ("Successor")  or any corporation  which
becomes the ultimate  parent  corporation  of the Company or any such  Successor
("Ultimate Parent") to expressly assume and agree in writing satisfactory to the
Employee  to perform  this  Agreement  in the same manner and to the same extent
that the Company would be required to perform it if no such succession had taken
place.  Failure of the Company to obtain  such  written  agreement  prior to the
effectiveness  of any such  succession  or  creation  of the parent  corporation
relationship  shall be a breach of this Agreement and shall entitle  Employee to
compensation  and  benefits  from the Company in the same amount and on the same
terms as he would be entitled to hereunder if he terminated  his  employment for
Good Reason, except that for purposes of implementing the foregoing, the date on
which any such succession (or creation of the parent  corporation  relationship)
becomes  effective  shall be  deemed  the Date of  Termination.  As used in this
Agreement, including, without limitation, in Section 3, the term "Company" shall
include any  Successor  and  Ultimate  Parent  which  executes  and delivers the
Agreement as provided for in this Section 12 or which otherwise becomes bound by
all terms and provisions of this Agreement by operation of law.

         (b) This Agreement and all rights of Employee  hereunder shall inure to
the   benefit  of  and  be   enforceable   by   Employee's   personal  or  legal
representatives,  executors,  administrators,  successors,  heirs, distributees,
devisees and legatees.

         13.  Indemnification.  During  the Term and for a period  of six  years
thereafter,  the Company  shall cause  Employee to be covered by and named as an
insured  under any policy or contract of insurance  obtained by it to insure its
directors  and  officers  against  personal  liability  for acts or omissions in
connection  with  service as an officer or director of the Company or service in
other  capacities  at the  request of the  Company.  The  coverage  provided  to
Employee  pursuant  to this  Section  8 shall  be of a scope  and on  terms  and
conditions at least as favorable as the most favorable  coverage provided to any
other officer or director of the Company (or any successor).



                                       -8-

<PAGE>



                  In addition,  to the maximum extent permitted under applicable
law, during the Term and for a period of six years thereafter, the Company shall
indemnify   Employee  against  and  hold  Employee   harmless  from  any  costs,
liabilities,  losses and  exposures  for  Employee's  services  as an  employee,
officer and director of the Company (or any successor).

         14.  Miscellaneous.  No  provision of this  Agreement  may be modified,
waived or discharged unless such waiver,  modification or discharge is agreed to
in  writing  and signed by  Employee  and such  officer  as may be  specifically
authorized  by the Board.  No waiver by either  party  hereto at any time of any
breach by the other party hereto of, or in  compliance  with,  any  condition or
provision of this  Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or  subsequent  time.  This  Agreement  is an  integration  of the parties
agreement;  no  agreement  or  representations,  oral or  otherwise,  express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Texas.

         15.  Counterparts.  This  Agreement  may be  executed  in  one or  more
counterparts,  each of which shall be deemed to be an original  but all of which
together will constitute one and the same instrument.

         16.  Arbitration.  Employee  shall be permitted  (but not  required) to
elect that any dispute or controversy  arising under or in connection  with this
Agreement be settled by  arbitration  in the city in which  Employee  resides at
such time in accordance with the rules of the American  Arbitration  Association
then in effect.  Judgment may be entered on the arbitrator's  award in any court
having jurisdiction. All legal fees and costs incurred by Employee in connection
with the  resolution of any dispute or controversy  under or in connection  with
this  Agreement  shall be paid by the  Company  as bills for such  services  are
presented by Employee to the Company.

         17. Prior Employment Agreement.  This Agreement supersedes and replaces
in full any existing employment agreement (written or oral) between the parties.

         to the Company  during the period from and including the Effective Date
         to and including the Termination Date, in an aggregate principal amount
         at any one time  outstanding  up to but not exceeding the lesser of (1)
         such Lender's  Commitment  and (2) the amount of such Lender's Share of
         the Allocated U.S. Borrowing Base as then in effect;  provided that the
         aggregate  principal amount of all Conventional  Loans and all Bid Rate
         Loans made by all of the Lenders  hereunder at any one time outstanding
         shall not  exceed the  Available  U.S.  Commitment,  as then in effect,
         minus the LC Exposure  then  outstanding.  Subject to the terms of this
         Agreement,  during the period from the Effective  Date to and including
         the  Termination  Date, the Company may borrow,  repay and reborrow the
         amount of the Available U.S. Commitment as then in effect. Conventional
         Loans may be Base Rate Loans or Eurodollar Loans.

         (ii) Unless  consented to in writing by the  Administrative  Agent,  no
         more than seven (7) Eurodollar Loans that are Conventional Loans may be
         outstanding  from each Lender at any time. For purposes of this Section
         2.01(a)(ii),   Eurodollar  Loans  having  different  Interest  Periods,
         regardless  of  whether  they  commence  on the  same  date,  shall  be
         considered separate Loans.

         (b)      Letters of Credit.

         (i) During the period  from and  including  the  Effective  Date to and
         including the Termination  Date, the  Administrative  Agent agrees,  on
         behalf of the  Lenders,  to extend  credit to the  Company by  issuing,
         renewing,  extending or reissuing  Letters of Credit for the account of
         the Company or any of its Subsidiaries;  provided that the aggregate LC
         Exposure at any one time outstanding shall not exceed the lesser of (A)
         the  Available  U.S.  Commitment  as then in effect minus the aggregate
         amount of all Conventional Loans and Bid Rate Loans then outstanding or
         (B) $50,000,000.

         (ii)  Each  of  the  Letters  of  Credit  shall  (A) be  issued  by the
         Administrative  Agent or The Chase  Manhattan Bank, an Affiliate of the
         Administrative  Agent,  (B) contain  such terms and  provisions  as are
         reasonably required by the Administrative  Agent in accordance with its
         customary  procedures,  (C) be for the account of the Company or one of
         its  Subsidiaries,  and (D) expire not later than the  earlier of three
         (3) years  after the  issue  date of such  Letter of Credit or five (5)
         days before the Termination Date.

         (iii) In  conjunction  with the  issuance  of a Letter of  Credit,  the
         Company shall execute a Letter of Credit Agreement. In the event of any
         conflict between any provision of a Letter of Credit Agreement and this
         Agreement,  OEI, the Company,  the Agents and the Lenders  hereby agree
         that the  provisions of this  Agreement  shall govern.  Such  conflicts
         include, without limitation, provisions in a Letter of Credit Agreement
         providing  for an  interest  rate  different  from  the  interest  rate
         provided  in this  Agreement  and  provisions  in a  Letter  of  Credit
         Agreement requiring or relating to collateral to secure the obligations
         thereunder.

         (c)      Bid Rate Loans.

         (i) Each Lender severally agrees that the Company from time to time may
         request  one or more of the  Lenders to make loans to the  Company on a
         non-pro  rata basis (each a "Bid Rate Loan") in the manner set forth in
         Section 2.02(g) during the period from and including the Effective Date
         to and  including  the  Termination  Date;  provided that (A) no Lender
         shall be  obligated  to make Bid Rate Loans to the Company  unless such
         Lender  has  irrevocably  offered to make a Bid Rate Loan  pursuant  to
         Section 2.02(g)(iii); and (B) following the making of any Bid Rate Loan
         by any Lender, the aggregate principal amount of all Conventional Loans
         and all Bid Rate Loans made by all of the Lenders  hereunder at any one
         time  outstanding  shall not exceed the Available U.S.  Commitment,  as
         then in effect, minus the LC Exposure then outstanding.  Bid Rate Loans
         may be Eurodollar  Loans or Absolute  Rate Loans.  For purposes of this
         Section 2.01(c)(i) and Section 2.02(g), Bid Rate Loans having different
         Interest Periods, regardless of whether they commence on the same date,
         shall be considered separate Loans.

         (ii) The making of any Bid Rate Loan to the Company by any Lender shall
         not be deemed to be a utilization of such Lender's Commitment (although
         it shall be deemed to be a utilization of the Available U.S. Commitment
         to effect the above  stated  limitation  and for all other  purposes of
         this Agreement).

         (d)      Loans under Prior Credit Agreements.  On the Effective Date:

         (i) the Company shall pay all accrued and unpaid fees outstanding under
         the Prior Credit  Agreements for the account of each "Lender" under the
         Prior Credit Agreements;

         (ii) each  "Base  Rate  Loan" and  "Eurodollar  Loan"  under each Prior
         Credit  Agreement shall be deemed to be repaid with the proceeds of new
         Loans under this Agreement;

         (iii) all letters of credit  issued under the Prior  Credit  Agreements
         (which are  scheduled  on  Schedule  2.01) shall be deemed to be issued
         under Section 2.02(d) hereof as of the Effective Date; and

         (iv) the Prior Credit  Agreements and the commitments  thereunder shall
         be superseded by this Agreement and such commitments shall terminate.

         Section  2.02 Borrowings,  Continuations  and Conversions;  Issuance of
                  Letters of Credit.

         (a) Borrowings.  The Company shall give the Administrative Agent (which
shall promptly  notify the Lenders)  advance  notice as hereinafter  provided of
each borrowing,  continuation,  and conversion hereunder of a Conventional Loan,
which shall  specify the aggregate  amount of such  borrowing,  continuation  or
conversion,  the  Type  and  date  (which  shall  be  a  Business  Day)  of  the
Conventional Loans to be borrowed,  continued or converted,  and (in the case of
Eurodollar Loans) the duration of the Interest Period therefor.

         (b)  Minimum  Amounts.  All  Base  Rate  Loans  (as  part  of the  same
borrowing)  shall  be in  aggregate  amounts  among  all  Lenders  of  at  least
$1,000,000 (or whole multiples  thereof) or the remaining  unused portion of the
Commitments.  All Eurodollar  Loans (as part of the same borrowing)  shall be in
aggregate  amounts among all Lenders of at least $3,000,000 (or a whole multiple
of $1,000,000 in excess  thereof).  All Bid Rate Loan  borrowings  under Section
2.02(g) shall be in amounts of at least $5,000,000.

         (c) Notices, Etc. for Conventional Loans. All borrowings, continuations
and  conversions  relating to  Conventional  Loans shall require advance written
notice from the Company to the Administrative Agent, in the form of Exhibit C-1,
or such other form as may be accepted by the  Administrative  Agent from time to
time, which in each case shall be irrevocable and effective only upon receipt by
the  Administrative  Agent not later  than (i) in the case of a Base Rate  Loan,
11:00  a.m.  Houston  time  on the  date  of  such  borrowing,  continuation  or
conversion;  and (ii) in the case of a Eurodollar  Loan, 12:00 noon Houston time
on a day which is not less than  three (3)  Business  Days  prior to the date of
such borrowing,  continuation  or conversion.  Not later than 12:00 noon Houston
time on the date specified for each borrowing  hereunder of a Conventional Loan,
each Lender shall make available the amount of the Conventional  Loan to be made
by  such  Lender  on  such  date  to the  Administrative  Agent,  at an  account
maintained by the  Administrative  Agent at the Principal Office, in immediately
available  funds for the account of the Company.  The amounts so received by the
Administrative  Agent  shall,  subject  to the  terms  and  conditions  of  this
Agreement,  be  made  available  to the  Company  by  depositing  the  same,  in
immediately  available  funds,  in an account of the Company  designated  by the
Company and maintained with the Administrative Agent at the Principal Office.

         (d) Letters of Credit. The Company shall give the Administrative  Agent
(which shall promptly notify the Lenders)  advance notice as provided in Section
2.02(c) not less than one (1) Business Day prior thereto of each request for the
issuance,  renewal,  or extension of a Letter of Credit  hereunder which request
shall  specify the amount of such Letter of Credit,  the date (which  shall be a
Business  Day) such Letter of Credit is to be issued,  renewed or extended,  the
duration  thereof,  the  beneficiary  thereof,  and  such  other  terms  as  the
Administrative  Agent may reasonably  request,  all of which shall be reasonably
satisfactory to the Administrative Agent. Subject to the terms and conditions of
this Agreement, on the date specified for the issuance,  renewal or extension of
a Letter of Credit, the  Administrative  Agent shall issue such Letter of Credit
to the beneficiary thereof.


                                      -23-

         (e) Continuation Options.  Subject to the terms of this Agreement,  the
Company may elect to continue all or any part of any  Eurodollar  Loan that is a
Conventional  Loan beyond the  expiration  of the then current  Interest  Period
relating  thereto by giving advance notice to the  Administrative  Agent of such
election,  specifying the amount of such Eurodollar Loan to be continued and the
Interest Period  therefor.  In the absence of such a timely and proper election,
the Company shall be deemed to have elected to convert such Eurodollar Loan to a
Base Rate  Loan.  All or any part of any  Eurodollar  Loan may be  continued  as
provided herein,  provided that (i) the principal amount of all or any part of a
Loan so continued  shall be not less than  $3,000,000  in the  aggregate for all
Lenders and (ii) no Default shall have occurred and be continuing.  If a Default
shall have occurred and be continuing,  each  Eurodollar Loan shall be converted
to a Base Rate Loan on the last day of the Interest Period  applicable  thereto.
The Company may not continue Bid Rate Loans.

         (f) Conversion Options. The Company may elect to convert any Eurodollar
Loan that is a  Conventional  Loan on the last day of the then current  Interest
Period  relating  thereto  to a Base Rate Loan by giving  advance  notice to the
Administrative  Agent of such election.  Subject to the terms of this Agreement,
the  Company  may elect to convert all or any part of a Base Rate Loan that is a
Conventional  Loan at any  time and from  time to time to a  Eurodollar  Loan by
giving advance notice to the Administrative  Agent of such election.  All or any
part of any outstanding Loan may be converted as provided herein,  provided that
any conversion of any Base Rate Loan into a Eurodollar Loan shall be (as to each
such Loan into which there is a conversion for an applicable Interest Period) in
the principal  amount not less than $3,000,000 in the aggregate for all Lenders.
If no Default shall have occurred and be continuing,  each Loan may be converted
as provided in this Section. If a Default shall have occurred and be continuing,
no Loan may be converted into a Eurodollar Loan. The Company may not convert Bid
Rate Loans.

         (g) Bid Rate Loans. The procedure for making Bid Rate Loans shall be as
follows:
         (i) The Company may  request  Bid Rate Loans  pursuant to this  Section
2.02(g)  from time to time from the  Lenders  by giving to the  Competitive  Bid
Auction  Agent a notice of a proposed bid rate  borrowing in  substantially  the
form of Exhibit C-2 hereto (a "Competitive Bid Request"),  which notice shall be
given not later than 10:00 a.m.,  Houston  time, on a Business Day not less than
four (4) Business  Days prior to the proposed  date the Bid Rate Loans are to be
borrowed if such Bid Rate Loans are  Eurodollar  Loans and not less than one (1)
Business Day prior to the proposed date the Bid Rate Loans are to be borrowed if
such Bid Rate Loans are Absolute Rate Loans.  The  Competitive Bid Request shall
specify the proposed date of the Bid Rate Loans to be borrowed (which shall be a
Business Day),  the aggregate  amount of the proposed Bid Rate Loans to be made,
which shall be not less than $5,000,000,  the duration  therefor,  the Type, the
interest  payment  date or dates  relating  thereto,  and any other  terms to be
applicable  to such Bid Rate Loan.  The Company  may request  offers to make Bid
Rate  Loans  for  up  to  three  (3)  different  Interest  Periods  in a  single
Competitive Bid Request. The terms of a Competitive Bid Request may not waive or
modify any of the conditions  precedent set forth herein.  The  Competitive  Bid
Auction Agent, as bid  administrator,  shall promptly notify the  Administrative
Agent and each  Lender of the  Company's  request  for Bid Rate Loans by sending
each Lender a copy of the Competitive Bid Request.


                                      -24-

<PAGE>



         (ii)  Each  Competitive  Bid  Request  must  be in  writing  and may be
delivered  (whether by the Company or the  Competitive  Bid Auction Agent as bid
administrator) by telegraph,  telex,  telecopy,  other facsimile transmission or
other suitable  means.  All responses to any Competitive Bid Request shall be in
writing and may be delivered to the  Competitive Bid Auction Agent by telegraph,
telex, telecopy, other facsimile transmission or other suitable means.

         (iii) Upon receipt of such  Competitive  Bid Request,  each Lender may,
if, in its sole discretion, it elects to do so, irrevocably offer to make one or
more Bid Rate Loans to the Company at a rate or rates of interest  specified  by
such Lender in its sole  discretion  by notifying  the  Competitive  Bid Auction
Agent,  as bid  administrator  (which shall promptly convey such response to the
Company),  in writing by supplying a Bid Rate Quote in substantially the form of
Exhibit C-3 hereto of its decision not later than 2:00 p.m.,  Houston  time,  on
the Business Day not less than four (4) Business Days prior to the proposed date
the Bid Rate  Loans are to be  borrowed  if such Bid Rate  Loans are  Eurodollar
Loans and before  10:00 a.m.  Houston  time on the same  Business Day as the Bid
Rate Loans are to be  borrowed  if such Bid Rate Loans are  Absolute  Rate Loans
(provided that if the Administrative Agent, in its capacity as a Lender, desires
to submit a Bid Rate Quote,  it shall on the relevant  date submit its quote not
later than 1:45 p.m.  and 9:45 a.m.,  respectively),  of the minimum  amount and
maximum  amount of each Bid Rate Loan such  Lender  would be  willing to make as
part of such  proposed Bid Rate Loan (which shall be not less than  $5,000,000),
the rate or rates of interest therefor,  the Applicable Lending Office therefor,
if  different,  and the period of time  during  which such  Lender's  offer with
respect to such rate or rates of interest shall remain open.  Such rate or rates
of  interest  may be  either  an  Absolute  Rate or based on the  definition  of
"Eurodollar  Rate,"  adding or  subtracting  any margin  which such Lender deems
appropriate.  Unless  otherwise  agreed by the Competitive Bid Auction Agent and
the Company, no Bid Rate Quote shall contain qualifying,  conditional or similar
language,  propose  terms  other than or in  addition  to those set forth in the
relevant  Competitive  Bid Request,  or be  conditioned  upon  acceptance by the
Company of all of the Bid Rate Loans for which  such  offer is being  made.  Bid
Rate Quotes not in compliance  with this clause (iii) may be  disregarded by the
Company in its sole discretion.

         (iv) The Company  shall,  in turn, not later than the expiration of the
period of time specified by such Lender during which its offer would remain open
(but in no event later than 10:30 a.m.  Houston time on the Business Day that is
three (3) Business  Days prior to the proposed  borrowing  date if such Bid Rate
Loans are  Eurodollar  Loans and not later than 11:00 a.m.  Houston  time on the
proposed  borrowing date if such Bid Rate Loans are Absolute Rate Loans), in its
sole  discretion,  either (A) cancel its request by giving the  Competitive  Bid
Auction Agent, as bid administrator, notice to that effect, or (B) accept one or
more  offers  made by  Lenders to make one or more Bid Rate  Loans,  in its sole
discretion,  by giving  notice to the  Competitive  Bid  Auction  Agent,  as bid
administrator,  of the  amount of each Bid Rate  Loan to be made by such  Lender
(which amount shall be equal to or greater than the minimum amount and less than
or equal to the maximum  amount,  that such Lender  specified to the Company for
such Bid Rate Loan  pursuant to clause (iii)  above,  but in no event shall such
amount be less than  $5,000,000).  In the event the Company  fails to cancel its
request  or to accept  the offer of a Lender to make one or more Bid Rate  Loans
within the time  periods  specified in this clause  (iv),  the Company  shall be
deemed to have  canceled its request for such Bid Rate Loan.  Upon notice that a
Competitive Bid Request has been canceled, the Competitive Bid Auction Agent, as
bid administrator,  shall give prompt notice thereof to the Administrative Agent
and the Lenders.


                                      -25-

<PAGE>



         (v) The Company shall have no  obligation to accept any offers,  but if
the Company accepts  offers,  it shall do so on the basis of the lowest Bid Rate
offered; and in the event bids are equal, the Company may accept any such offers
in its sole discretion. If the Company accepts one or more of the offers made by
the Lenders,  the  Competitive Bid Auction Agent,  as bid  administrator,  shall
promptly  notify  the  Administrative  Agent  and each  Lender  whose  offer was
accepted  of the date and  aggregate  amount  of such  Bid Rate  Loan and  shall
promptly  notify all other  Lenders whose offers were not accepted of such fact.
The  benefit  of any  notice or time  periods  specified  above in this  Section
2.02(g)  relating to Bid Rate Loans from any Lender may be waived by the Company
or such  Lender,  as the case may be,  without  the  consent or  approval of the
Competitive Bid Auction Agent or any other Lender.

         (vi) Not later than 1:00 p.m.,  Houston time, on the date specified for
each borrowing  hereunder of a Bid Rate Loan,  each Lender that has had its bids
accepted  shall make available the amount of such Bid Rate Loan to be made by it
on such  date to the  Administrative  Agent,  at an  account  maintained  by the
Administrative  Agent at the Principal Office,  in immediately  available funds,
for the account of the  Company.  The amounts so received by the  Administrative
Agent shall,  subject to the terms and conditions of this  Agreement,  including
without  limitation the  satisfaction of all conditions  precedent  specified in
Section  6.02,  be made  available  to the Company by  depositing  the same,  in
immediately  available  funds,  in an account of the Company,  designated by the
Company, maintained with the Administrative Agent at the Principal Office.

         (vii) If any  Lender  makes a new Bid Rate Loan  hereunder  on a day on
which the Company is to repay all or any part of any  outstanding  Bid Rate Loan
from such Lender,  such Lender shall apply the proceeds of its new Bid Rate Loan
to make such  repayment  and only an  amount  equal to the  difference  (if any)
between  such amount  being  borrowed and such amount being repaid shall be made
available  by such  Lender to the  Company or  remitted  by the  Company to such
Lender, as the case may be.

         (viii) The  indebtedness  of the Company  resulting  from each Bid Rate
Loan made to the Company shall be evidenced by the records of each Lender making
a Bid  Rate  Loan and by the Bid  Rate  Note  therefor.  Such  records  shall be
presumed  correct;  provided  that the  failure  of any  Lender to make any such
notation  on its Bid Rate Note  shall not affect the  Company's  obligations  in
respect of its Bid Rate Loan from such Lender.

         (ix) All notices to any Lender  required by this Section  2.02(g) shall
be made in accordance with Section 12.02 and the Competitive Bid  Administrative
Questionnaire  most recently  placed on file by each Lender with the Competitive
Bid Auction Agent or the Administrative Agent.

         (x) The Chase Manhattan Bank, an Affiliate of the Administrative Agent,
hereby agrees to be a party to this  Agreement for the sole purpose of acting as
Competitive  Bid  Auction  Agent  and  performing  all  duties  assigned  to the
Competitive Bid Auction Agent as the bid administrator hereunder.

         Section 2.03      Extensions and Changes of Commitments.

         (a)      Extension of Termination Date.

                  (i) At any time during the 60-day  period  beginning  February
1st of a year and ending on April 1st of such year,  the  Company may request in
writing  that,  in  connection  with  the  forthcoming  redetermination  of  the
Borrowing Base, the Lenders and the Canadian Lenders extend the Termination Date
for a period of one (1) additional year; provided, that any such extension shall
require  the  consent of all of the  Lenders  and the  Canadian  Lenders,  which
consent may be withheld in each such  Person's  sole  discretion;  and provided,
further, that if any Lender or Canadian Lender has not responded to such request
in writing within 45 days after receipt of the written request of the Company by
the Administrative Agent, such failure shall be deemed a denial of said request.

                  (ii) Notwithstanding the foregoing clause (i), if the Required
Lenders  (but not all Lenders and  Canadian  Lenders)  have agreed to extend the
then applicable  Termination  Date as provided in Section  2.03(a)(i),  then the
Company (or UMC Canada) may terminate,  in whole but not in part, the Commitment
of any Lender or the Canadian  Subcommitment  of any  Canadian  Lender which has
refused to grant such extension (a  "Terminated  Lender") upon five (5) Business
Days'  notice,  during the period  commencing  on the  expiration  of the 45-day
notice  period  referred to above (or,  if  earlier,  the date of receipt by the
Company of notice of such  Terminated  Lender's  refusal) and ending on the date
thirty (30) days after the end of such 45-day  period,  by giving written notice
to the Terminated  Lender and the  Administrative  Agent (or the Canadian Agent)
(such  notice  referred  to herein as a "Notice  of  Termination").  In order to
effect the  termination  of the Commitment  (or Canadian  Subcommitment)  of the
Terminated  Lender,  the Company (or UMC Canada) shall:  (1) obtain an agreement
with one or more  Lenders  (or  Canadian  Lenders) to  increase  its  respective
Commitment (or Canadian  Subcommitment) and/or (2) request any one or more other
financial  institutions  to become  parties to this  Agreement  (or the Canadian
Credit Agreement) in place of such Terminated  Lender;  provided,  that any such
financial  institution is reasonably  acceptable to the Administrative Agent (or
the Canadian  Agent) and becomes party to this Agreement (or the Canadian Credit
Agreement) by executing an Assignment and  Acceptance  (or its equivalent  under
the Canadian Credit Agreement) (the Lender or other financial  institutions that
agree to accept in whole or in part the Commitment  (or Canadian  Subcommitment)
of the Terminated  Lender being referred to herein as the "Replacement  Lender")
and to  assume  the Loans of the  Terminated  Lender,  such  that the  aggregate
increased  and/or  accepted  Commitments  (or  Canadian  Subcommitments)  of the
Replacement  Lender(s)  under  clauses  (1) and (2)  equal  the  Commitment  (or
Canadian Subcommitment) of the Terminated Lender. If the Company (or UMC Canada)
is unable to obtain one or more Replacement Lenders to accept the Commitment (or
Canadian  Subcommitment) and to assume the Loans of the Terminated Lender, then,
if no Default  or Event of Default  has  occurred  at the time of such  proposed
extension,   the  Company   shall  either   elect  by  written   notice  to  the
Administrative  Agent to forego the requested  extension or reduce the Aggregate
Commitments (or, if applicable,  the aggregate  Canadian  Subcommitments)  by an
amount equal to the  Commitment  (or Canadian  Subcommitment)  of the Terminated
Lender.  (The  failure to give such  notice  will be deemed an  election  by the
Company to forego the requested extension.) If a Default or Event of Default has
occurred and is continuing,  no extension will be permitted  without the consent
of all Lenders and the Canadian Lenders.  Any assignment to a Replacement Lender
shall be  effected  pursuant  to Section  12.06(b)  or Section  12.03(b)  of the
Canadian Credit Agreement, as applicable.

                                      -27-

<PAGE>



         (b) Optional  Reduction.  The Company shall have the right to terminate
or to reduce the Aggregate Commitments at any time or from time to time upon not
less than one (1)  Business  Day's prior  written  notice to the  Administrative
Agent (which shall  promptly  notify the  Lenders) of each such  termination  or
reduction,  which notice shall specify the effective date thereof and the amount
of any such  reduction  (which shall not be less than  $5,000,000,  or any whole
multiple of $1,000,000 in excess thereof).  Such notice shall be irrevocable and
effective only upon receipt by the Administrative Agent.

         (c) Reinstatement. The Aggregate Commitments once terminated or reduced
may not be reinstated.  The amount of the Available U.S. Commitment may increase
or decrease  from time to time in accordance  with the terms hereof,  including,
but not limited to Section 2.09.

         Section 2.04      Facility Fee and Other Fees.

         (a) Facility Fee. The Company shall pay to the Administrative Agent for
the account of the Lenders a facility fee (the  "Facility  Fee") in an aggregate
amount equal to the Facility Fee Rate times an amount equal to the average daily
Available U.S. Commitment.  The Facility Fee will accrue for the period from and
including the Effective  Date to and including  the  Termination  Date,  without
regard  to the  outstanding  principal  amount  of  Loans  outstanding.  Accrued
Facility  Fees shall be payable  in  arrears on each  Quarterly  Date and on the
Termination Date.

         (b)  Letter  of  Credit  Fee.   The  Company   agrees  to  pay  to  the
Administrative  Agent for the account of the Lenders a quarterly fee for issuing
the Letters of Credit,  calculated  separately for each Letter of Credit,  in an
aggregate  amount for each  Letter of Credit  equal to 1/4 of the product of (i)
the LC Fee Rate, as then in effect,  and (ii) the daily average  balance  during
such  quarter  of the amount of the  Letter of Credit  upon which  drafts may be
drawn from time to time  commencing  on the date of  issuance  of such Letter of
Credit (or on the date of Initial Funding for Letters of Credit issued under the
Prior  Credit  Agreements  and  outstanding  on the  date of  Initial  Funding);
provided that each respective  Letter of Credit shall bear an aggregate  minimum
quarterly fee equal to $350, or such other fee as may be specifically  agreed by
the Company and the  Administrative  Agent in each  respective  Letter of Credit
Agreement.  All fees for all Letters of Credit  (including all fees incurred for
any  amendments  to  Letters  of  Credit)  shall be  payable  in arrears on each
Quarterly Date.

         (c) Issuing Fee. In addition to the fees described in Section  2.04(b),
the  Company  shall  pay to the  Administrative  Agent  for  its own  account  a
quarterly fee for issuing each Letter of Credit,  calculated separately for each
Letter of Credit,  in an aggregate amount for each Letter of Credit equal to 1/4
of the product of (i) .125% per annum and (ii) the daily average  balance during
such  quarter  of the amount of the  Letter of Credit  upon which  drafts may be
drawn from time to time  commencing  on the date of  issuance  of such Letter of
Credit (or on the date of Initial Funding for Letters of Credit issued under the
Prior Credit  Agreements and  outstanding on the date of Initial  Funding).  All
fees for all Letters of Credit  (including  all fees incurred for any amendments
to Letters of Credit) shall be payable in arrears on each Quarterly Date.

         (d)  Competitive  Bid   Administration   Fee.  Upon  delivery  of  each
Competitive Bid Request to the  Administrative  Agent,  the Company shall pay to
the Competitive Bid Auction Agent, as bid

                                      -28-

administrator,  for its own account, a bid  administration fee of $1,000,  which
fee shall be due and payable  regardless  of whether or not the Company  cancels
its request or accepts any offers from any Lender.

         (e) Fee Letters.  The Company shall pay to the Administrative Agent and
its Affiliates and the Syndication  Agent such other amounts as are set forth in
the Fee Letters on the dates set forth therein.

         Section  2.05  Lending  Offices.  The  Loans of each  Type made by each
Lender shall be made and maintained at such Lender's  Applicable  Lending Office
for Loans of such Type.

         Section 2.06 Several Obligations. The failure of any Lender to make any
Loan to be made by such  Lender  or to  provide  funds for  disbursements  under
Letters of Credit on the date  specified  therefor  shall not  relieve any other
Lender of its  obligation  to make its Loan or provide  such funds on such date,
but no Lender shall be responsible for the failure of any other Lender to make a
Loan to be made by such other Lender or to provide  funds to be provided by such
other Lender.

         Section 2.07      Notes.

         (a)  Conventional  Notes.  The  Conventional  Loans made by each Lender
shall be evidenced by a single  promissory note of the Company in  substantially
the form of Exhibit A-1,  dated as of the Effective Date or such later date that
a Lender  becomes  a party  hereto,  payable  to the  order of such  Lender in a
principal  amount equal to the maximum amount of its Commitment as originally in
effect and otherwise duly completed. The date, amount, Type and interest rate of
each Conventional Loan made by each Lender,  and all payments made on account of
the principal thereof,  shall be recorded by such Lender on its books and, prior
to any  transfer  of the  Conventional  Loan Note held by it,  endorsed  by such
Lender  on the  schedule  attached  to such  Note or any  continuation  thereof;
provided that the failure of a Lender to make any notation  shall not affect the
Company's obligations in respect of such Loan.

         (b) Bid Rate  Notes.  The Bid Rate Loans made by each  Lender  shall be
evidenced by a single  promissory note of the Company in substantially  the form
of Exhibit A-2,  dated as of the Effective Date or such later date that a Lender
becomes a party hereto, payable to such Lender and otherwise duly completed. The
date, amount,  Type,  interest rate and maturity date of each Bid Rate Loan made
by each Lender, and all payments made on account of the principal thereof, shall
be recorded by such  Lender on its books and,  prior to any  transfer of the Bid
Rate Note held by it,  endorsed by such Lender on the schedule  attached to such
Note or any continuation thereof;  provided that the failure of a Lender to make
any notation shall not affect the Company's obligations in respect of such Loan.

         (c) No Right to  Subdivide.  No Lender  shall be  entitled  to have its
Notes  subdivided,  by exchange for promissory notes of lesser  denominations or
otherwise,  except  in  connection  with a  permitted  assignment  of all or any
portion  of such  Lender's  Commitment,  Loans and  Notes  pursuant  to  Section
12.06(b).

         Section 2.08      Prepayments.

         (a) Optional Prepayments.  The Company may prepay Conventional Loans on
any Business Day upon notice to the  Administrative  Agent (which shall promptly
notify the  Lenders),  which  notice (i) shall be given by the Company not later
than 12:00 noon Houston time on such Business Day, (ii) shall specify the amount
of the  prepayment  (which shall be not less than  $1,000,000  or the  remaining
balance of Base Rate Loans outstanding,  if less) and (iii) shall be irrevocable
and effective  only upon receipt by the  Administrative  Agent.  Interest on the
principal  prepaid,  accrued  to the  prepayment  date,  shall  be  paid  on the
prepayment  date. Any prepayment of any Eurodollar Loans shall be subject to the
provisions of Section 5.05. The Company may not prepay Bid Rate Loans;  provided
that the foregoing  shall not prevent an  acceleration  of the maturity of a Bid
Rate Loan upon the occurrence and continuance of an Event of Default.

         (b) Mandatory Prepayment Upon Reduction of Commitment. If, after giving
effect to any termination or reduction of the Aggregate  Commitments pursuant to
Section 2.03, the sum of the outstanding aggregate principal amount of the Loans
and the LC Exposure exceeds the Aggregate Commitments, then the Company shall on
the date of such  termination  or  reduction  pay or prepay  the  amount of such
excess for application first,  towards reduction of all amounts previously drawn
under Letters of Credit,  but not yet funded as a Conventional  Loan pursuant to
Section 4.07(b) or reimbursed,  second,  if necessary,  towards reduction of the
outstanding  principal  balance of the Conventional Loan Notes by prepaying Base
Rate Loans, if any, then outstanding, third, if necessary, toward a reduction of
the outstanding  principal  balance of the Conventional  Loan Notes by prepaying
Eurodollar  Loans, if any, then outstanding,  fourth, if necessary,  paying such
amount to the Administrative Agent as cash collateral for outstanding Letters of
Credit,  which  amount  shall  be  held  by the  Administrative  Agent  as  cash
collateral  to secure the Company's  obligation to reimburse the  Administrative
Agent and the Lenders  for  drawings  under the Letters of Credit and fifth,  if
necessary, paying such amount to the Administrative Agent as cash collateral for
outstanding  Bid Rate Loans,  which amount  shall be held by the  Administrative
Agent as cash  collateral to secure the Company's  obligation  under such Loans.
The Company  shall on the date of such  termination  or  reduction  also pay any
amounts payable pursuant to Section 5.05 in connection therewith.

         (c) Mandatory Prepayment Upon  Redetermination.  Upon any adjustment or
redetermination  of the  amount of the  Borrowing  Base in  accordance  with (i)
Section  2.09,  (ii)  8.05(d),  (iii)  9.01(e),  (iv)  9.01(h)(ii),  (v) Section
9.01(o),  (vi)  Section  9.16(b)  or (vii)  Section  9.21 or  otherwise,  if the
adjusted or  redetermined  Borrowing  Base is less than the sum of the aggregate
outstanding  principal  amount of the Loans,  the LC Exposure  and the  Canadian
Indebtedness (a "Borrowing Base  Deficiency"),  then the Company shall within 90
days of receipt of written  notice  thereof either (i) take such steps as may be
approved by the Administrative Agent to increase the Borrowing Base by an amount
equal to or greater than the amount of such  Borrowing  Base  Deficiency or (ii)
prepay the amount of such  Borrowing  Base  Deficiency  for  application  first,
towards reduction of all amounts  previously drawn under Letters of Credit,  but
not yet funded as a Conventional Loan pursuant to Section 4.07(b) or reimbursed,
second, if necessary,  towards reduction of the outstanding principal balance of
the  Conventional  Loan Notes and Canadian  Indebtedness  by prepaying Base Rate
Loans,  as defined herein and as defined in the Canadian  Credit  Agreement,  if
any,  then  outstanding,  third,  if necessary,  towards  prepayment of Bankers'
Acceptances issued and outstanding under the Canadian Credit Agreement,  fourth,
if necessary, towards

                                      -30-

<PAGE>



a reduction of the outstanding  principal balance of the Conventional Loan Notes
by  prepayment  of  Eurodollar  Loans,  if  any,  then  outstanding,  fifth,  if
necessary,  towards payment of such amount to the  Administrative  Agent as cash
collateral for outstanding Letters of Credit,  which amount shall be held by the
Administrative  Agent as cash  collateral to secure the Company's  obligation to
reimburse  the  Administrative  Agent and the  Lenders  for  drawings  under the
Letters of Credit and sixth, if necessary, towards payment of such amount to the
Administrative  Agent as cash collateral for  outstanding Bid Rate Loans,  which
amount shall be held by the  Administrative  Agent as cash  collateral to secure
the  Company's  obligation  under such  Loans.  The  Company  shall also pay any
amounts payable pursuant to Section 5.05 in connection therewith.

         (d) Prepayment  Following  Reallocation.  Upon any  reallocation of the
Borrowing Base in accordance with Section 2.09, if either (i) the Available U.S.
Commitment is less than the sum of the aggregate outstanding principal amount of
the Loans and the LC Exposure or (ii) the Available  Canadian  Subcommitment  is
less than the  Canadian  Indebtedness,  then in either case,  the Company  shall
within 90 days of receipt of written notice  thereof,  prepay the amount of such
excess in a manner  consistent with the  application  order specified in Section
2.08(c).

         (e) No Penalty or Premiums.  Subject to  compensation  requirements  of
Section 5.05, all prepayments shall be without premium or penalty.

         Section 2.09      Borrowing Base.

                  (a)  Allocation.  (i) For the period  from and  including  the
         Effective Date to but not including the first Redetermination Date, the
         amount of the Borrowing  Base shall be  $600,000,000  and the Threshold
         Amount shall be  $525,000,000.  The  Borrowing  Base may not exceed the
         Aggregate Commitments.

         (ii) Subject to the terms of Section 2.09(a)(i), the Borrowing Base and
         the Threshold  Amount shall be  determined in accordance  with Sections
         2.09(b),  (c) and (d) by the  Technical  Agents  with the  approval  or
         deemed approval of the Required Lenders  (provided that any increase in
         the Borrowing Base shall require the approval or deemed approval of all
         the Lenders  and the  Canadian  Lenders).  The  Borrowing  Base and the
         Threshold  Amount  will be  redetermined  annually in  accordance  with
         Section 2.09(b),  commencing May 1, 1999. Upon any  redetermination  of
         the Borrowing Base and the Threshold Amount, such redetermination shall
         remain in effect until the next successive Redetermination Date.

         (iii) The  Borrowing  Base may be allocated  between the Company  under
         this  Agreement  and UMC Canada  under the Canadian  Credit  Agreement.
         Subject  to the  other  terms of this  Agreement,  the  Allocated  U.S.
         Borrowing Base in effect from time to time shall  represent the maximum
         amount of credit in the form of Loans and Letters of Credit (subject to
         the Aggregate  Commitments and the other  provisions of this Agreement)
         that the  Lenders  will  extend to the Company at any one time prior to
         the  Termination  Date. On the Effective  Date, the Allocated  Canadian
         Borrowing  Base shall be $7,000,000  resulting in an initial  Allocated
         U.S. Borrowing Base of $593,000,000.

         (iv) The Company at any time shall have the right to request in writing
         to the  Administrative  Agent,  Canadian Agent and the Canadian Lenders
         that the  Canadian  Lenders,  in their sole  discretion,  increase  the
         Allocated  Canadian  Borrowing  Base;  provided  that any such increase
         shall require the approval of all of the Canadian Lenders; and provided
         further  that the Company may not make such request more than three (3)
         times during any twelve month period.  Within ten (10) Business Days of
         the  receipt by the  Canadian  Lenders of such  request,  the  Canadian
         Lenders shall give written notice to the Company and the Administrative
         Agent  of their  approval  or  disapproval  of such  increase.  If such
         increase is approved,  each Lender which is also a Canadian  Lender (or
         who has an Affiliated Canadian Lender) shall have its pro rata share of
         the  Allocated  U.S.  Borrowing  Base reduced by an amount equal to its
         corresponding  increase in the Allocated  Canadian  Borrowing Base. The
         revised Allocated U.S.  Borrowing Base and Allocated Canadian Borrowing
         Base  (and,  if  applicable,   Commitment   Percentages)  shall  become
         effective  upon the  distribution  by the  Administrative  Agent to the
         Company, all Lenders and all Canadian Lenders of written notice thereof
         which  shall  occur not later  than three (3)  Business  Days after its
         receipt of the notice of increase.

         (v) The  Company at any time shall have the right to request in writing
         to the Administrative Agent, the Canadian Agent and the Lenders who are
         also Canadian  Lenders (or who have Affiliated  Canadian  Lenders) that
         such  Lenders who are also  Canadian  Lenders  (or who have  Affiliated
         Canadian  Lenders),  in their sole  discretion,  permit the  Company to
         decrease the Allocated Canadian Borrowing Base;  provided that any such
         change shall require the approval of all of such Lenders;  and provided
         further  that the Company may not make such request more than three (3)
         times during any twelve month period.  Within ten (10) Business Days of
         the receipt by such Lenders of such  request,  such Lenders  shall give
         written  notice to the  Company and the  Administrative  Agent of their
         approval or disapproval  of such change.  If such decrease is approved,
         each such Lender  shall have its pro rata share of the  Allocated  U.S.
         Borrowing  Base  increased  by an  amount  equal  to its  corresponding
         decrease  in  the  Allocated   Canadian  Borrowing  Base.  The  revised
         Allocated  U.S.  Borrowing Base and Allocated  Canadian  Borrowing Base
         (and, if applicable,  Commitment  Percentages)  shall become  effective
         upon the distribution by the Administrative  Agent to the Company,  all
         Lenders and all Canadian  Lenders of written notice thereof which shall
         occur not later than three (3)  Business  Days after its receipt of the
         notice of increase.

         (vi)  Reallocations of the Allocated U.S.  Borrowing Base and Allocated
         Canadian Borrowing Base may affect the Commitment  Percentage set forth
         on Annex I, but  shall  not,  without  the prior  agreement  of all the
         Lenders and the Company, affect the Global Commitment Percentage.

         (b)  Redetermination.  On or before April 1st of each year,  commencing
April 1, 1999, the Technical Agents shall propose in writing to the Company, the
Lenders and the Canadian  Lenders a new Borrowing  Base and Threshold  Amount in
accordance with Section 2.09(c) (assuming receipt by the Technical Agents of the
Engineering  Reports in a timely and complete  manner).  After  having  received
notice of such proposal by the Technical  Agents,  each Lender and each Canadian
Lender  shall  have ten (10) days to agree with such  proposal  or  disagree  by
proposing an alternate Borrowing Base and Threshold Amount. If at the end of ten
(10) days, any Lender or Canadian  Lender has not  communicated  its approval or
disapproval, such silence shall be deemed to be an approval. If, however, at the
end of such 10-day

                                      -32-

<PAGE>



period,  the Required  Lenders have not approved or deemed to have approved,  as
aforesaid,  the proposed Borrowing Base and Threshold Amount, then the Borrowing
Base and  Threshold  Amount  shall be  determined  in  accordance  with  Section
2.09(d). After such redetermined Borrowing Base and Threshold Amount is approved
by the  Required  Lenders or is  otherwise  determined  as  provided  in Section
2.09(d),  it shall become  effective and applicable to the Company,  the Agents,
the Lenders and the Canadian Lenders as of the next succeeding May 1st.

         (c) Engineering  Reports.  Upon receipt of the Reserve Reports and such
other reports, data, and supplemental  information as may, from time to time, be
reasonably  requested  by the  Required  Lenders  (the  "Engineering  Reports"),
together with a certificate from the President or chief financial officer of the
Company that, to the best of his knowledge and in all material respects, (i) the
information  contained in the Engineering Reports is true and correct,  (ii) the
certificate  identifies the Properties  covered by the Engineering  Reports that
have not been previously included in any prior Engineering Reports, and (iii) no
other Oil and Gas Properties have been sold since the date of the last Borrowing
Base determination  except as set forth on an exhibit to the certificate,  which
certificate  shall  list  all Oil  and Gas  Properties  sold or  disposed  of in
compliance  with  Section  9.16 (or  pursuant to a waiver  thereof)  and in such
detail as reasonably required by the Technical Agents, the Technical Agents will
evaluate such  information.  The Technical  Agents,  with the approval or deemed
approval of the Required Lenders as set forth in Section 2.09(b), but subject to
the terms of Section 2.09(d), shall redetermine the Borrowing Base and Threshold
Amount  based  upon such  information  and such  other  information  (including,
without  limitation,  the Indebtedness) as the Technical Agents deem appropriate
and  consistent  with their normal oil and gas lending  criteria as it exists at
the  particular  time  (including,  without  limitation,  the  status  of  title
information  with  respect to  Properties  in the  Engineering  Reports  and the
existence  of any other  Debt  including,  without  limitation,  the Debt of UMC
Canada under the  Canadian  Credit  Agreement).  Such  redetermination  shall be
accomplished  not later than and effective as of the first (1st) day of each May
of each  calendar  year,  assuming  that the Company  shall have  furnished  the
Engineering Reports in a timely and complete manner.

         (d) Consensus and Failure of Consensus. Except as hereinafter provided,
the decision of the Required  Lenders  with  respect to any  Borrowing  Base and
Threshold Amount  determination shall control;  however, if the Required Lenders
have not approved or are not deemed to have approved the Borrowing  Base and the
Threshold  Amount as of the date such a  determination  is called for in Section
2.09(b), the Technical Agents shall poll the Lenders and the Canadian Lenders to
ascertain the highest  Borrowing Base and Threshold  Amount then acceptable to a
number of Lenders and Canadian  Lenders  sufficient to  constitute  the Required
Lenders for purposes of this Section 2.09 and such amounts shall then become the
Borrowing  Base and the Threshold  Amount for the next  Redetermination  Period.
Notwithstanding the foregoing,  however,  any increase in the Borrowing Base and
the  Threshold  Amount  shall  require  the  consent of all the  Lenders and the
Canadian Lenders.

         (e) Interim  Redeterminations.  The Company may, at its option one time
during a 12 month period,  initiate an interim  redetermination of the Borrowing
Base and the Threshold Amount. The Administrative Agent (at the direction of the
Required  Lenders,  in their  option) may, one time during any 12 month  period,
initiate an interim  redetermination  of the  Borrowing  Base and the  Threshold
Amount.

         (f)      Short-Term Pari Passu Debt; Other Adjustments.

                                      -33-

<PAGE>



         (i) The Technical  Agents shall  calculate  the Borrowing  Base and the
         Threshold  Amount for any  Redetermination  Period by (A)  reducing the
         amount which would have been the  Borrowing  Base in the absence of any
         Short-Term  Pari Passu Debt by an amount  equal to the amount of Short-
         Term Pari Passu Debt  outstanding  as of the  Redetermination  Date for
         such Redetermination Period and (B) reducing the Threshold Amount by an
         amount  equal to the  product of the  amount of Short-  Term Pari Passu
         Debt   outstanding   as  of   the   Redetermination   Date   for   such
         Redetermination  Period and a fraction  the  numerator  of which is the
         amount which would have been the Threshold Amount but for the effect of
         this clause (i) and denominator of which is the amount which would have
         been the  Borrowing  Base but for the  effect of this  clause  (i).  In
         addition,  if during any  Redetermination  Period,  any Short-Term Pari
         Passu Debt is  incurred or  assumed,  the amount of the then  effective
         Borrowing  Base shall  automatically  reduce for the  remainder of such
         Redetermination  Period by an amount equal to the amount of  Short-Term
         Pari Passu Debt so incurred or assumed and the  Threshold  Amount shall
         likewise reduce in a pro rata fashion.

         (ii) The Borrowing  Base and the  Threshold  Amount are also subject to
         adjustment as set forth in Sections 8.05(d), 9.01(e)(iii), 9.01(h)(ii),
         9.01(o), 9.16(b) and 9.21.

                                   ARTICLE III
                       Payments of Principal and Interest

         Section  3.01  Repayment  of  Loans.   The  Company  will  pay  on  the
Termination Date to the Administrative  Agent for the account of each Lender the
then-outstanding principal amount of each Conventional Loan made by such Lender.
Notwithstanding  the foregoing  sentence,  each Bid Rate Loan will mature and be
payable in full on the last day of the Interest  Period therefor and the Company
agrees to pay to the  Administrative  Agent for the account of the Lender making
such Bid Rate Loan the amount of such Bid Rate Loan in full on such day.

         Section 3.02      Interest.

         (a) The Company will pay to the Administrative Agent for the account of
each Lender  interest on the unpaid  principal  amount of each Loan made by such
Lender for the period  commencing  on the date of such Loan to but excluding the
date such Loan shall be paid in full, at the following rates per annum:

         (i) if such Loan is a Base Rate Loan,  the Base Rate (as in effect from
         time to time) plus the Applicable Margin for Base Rate Loans, but in no
         event to exceed the Highest Lawful Rate;

         (ii) if such Loan is a Eurodollar Loan that is a Conventional Loan, for
         each Interest  Period  relating  thereto,  the Eurodollar Rate for such
         Loan  plus  the  Applicable   Margin  for  Eurodollar  Loans  that  are
         Conventional Loans, but in no event to exceed the Highest Lawful Rate;

         (iii) if such Loan is a  Eurodollar  Loan that is a Bid Rate Loan,  for
         each  Interest  Period  relating  thereto,   the  Eurodollar  Rate  for
         Eurodollar  Loans plus or minus any margin as may be agreed between the
         Company and the Lender  making  such Bid Rate Loan,  but in no event to
         exceed the Highest Lawful Rate; and


                                      -34-

<PAGE>



         (iv) if such Loan is an Absolute Rate Loan,  for each  Interest  Period
         relating  thereto,  such rate per annum as may be  agreed  between  the
         Company and the Lender  making  such Bid Rate Loan,  but in no event to
         exceed the Highest Lawful Rate.

         Notwithstanding   the   foregoing,   the   Company   will  pay  to  the
Administrative  Agent for the account of each Lender  interest at the applicable
Post-Default Rate on any principal of any Loan made by such Lender,  and, to the
fullest  extent  permitted  by law,  on any other  amount  payable by OEI or the
Company  hereunder  or under any Loan  Document,  that shall not be paid in full
when due (whether at stated  maturity,  by acceleration  or otherwise),  for the
period commencing on the due date thereof until the same is paid in full, but in
no event to exceed the Highest Lawful Rate.

         (b) Accrued interest on each Base Rate Loan shall be payable  quarterly
on each Quarterly  Date.  Accrued  interest on each Eurodollar Loan and Absolute
Rate Loan shall be payable on the last day of the Interest  Period therefor and,
if such  Interest  Period is longer than three  months or ninety  (90) days,  at
three-month or ninety (90) day intervals,  as  appropriate,  following the first
day of such Interest Period. In any event,  interest payable at the Post-Default
Rate shall be payable from time to time on demand and interest on any Eurodollar
Loan that is converted  into a Base Rate Loan  pursuant to Section 5.04 shall be
payable on the date of conversion (but only to the extent so converted).

         (c) Promptly after the  determination of any interest rate provided for
herein or any change therein,  the Administrative Agent shall notify the Company
and the Lenders to which such  interest is payable  thereof.  Upon notice to the
Administrative  Agent of the incurrence of Debt pursuant to Section 8.01(g), the
incurrence of any Pari Passu Debt or Subordinated  Debt and/or any change in the
amount of the Indebtedness  (including the LC Exposure) outstanding hereunder or
the amount of the Canadian Indebtedness under the Canadian Credit Agreement, the
Administrative  Agent shall  promptly  determine the Debt Coverage Ratio and, in
the event such  circumstances  result in a change in the Applicable  Margin, the
Facility Fee Rate and the LC Fee Rate, the Administrative Agent shall notify the
Lenders and the Company.  Such new Applicable  Margin, the Facility Fee Rate and
the LC Fee Rate will be applicable  until the next day on which events described
in this Section  3.02(c)  result in a change and notice  thereof is given by the
Administrative Agent.

                Payments; Pro Rata Treatment; Computations; Etc.

         Section 4.01 Payments.  Except to the extent otherwise provided herein,
all payments of principal,  interest and other amounts to be made by the Company
under  this  Agreement,  the  Notes and other  Loan  Documents  shall be made in
Dollars,  in immediately  available  funds,  to the  Administrative  Agent at an
account  maintained by the  Administrative  Agent at the Principal  Office,  not
later  than 1:00 p.m.  Houston  time on the date on which  such  payments  shall
become due (each such payment made after such time on such due date to be deemed
to have been made on the next  succeeding  Business  Day).  The  Company  shall,
subject  to  Section  4.02,  at the  time of  making  each  payment  under  this
Agreement,  any Note or any other Loan Document,  specify to the  Administrative
Agent the Loans,  Letters  of Credit or other  amounts  payable  by the  Company
hereunder to which such payment is to be applied (and in the event that it fails
to so  specify,  and such day is not a  Quarterly  Date or other  day on which a
payment of either  interest or principal  is due,  then such  payments  shall be
applied in the following order: first, to interest

                                      -35-

accrued on Conventional Loans maintained as Base Rate Loans,  second, any excess
to reduce the aggregate  principal amount then outstanding on Conventional Loans
maintained  as Base Rate  Loans,  third,  any  excess  to  interest  accrued  on
Conventional  Loans  maintained  as Eurodollar  Loans,  and fourth any excess to
reduce the aggregate  principal  amount then  outstanding on Conventional  Loans
maintained  as  Eurodollar  Loans;  provided  that if an  Event of  Default  has
occurred and is continuing, the Administrative Agent may distribute such payment
to the Lenders in such manner as it or the Majority  Lenders may determine to be
appropriate,   subject  to  Section   4.02).   Each  payment   received  by  the
Administrative  Agent under this Agreement,  any Note or any other Loan Document
for  the  account  of a  Lender  shall  be paid  promptly  to  such  Lender,  in
immediately  available  funds, for account of such Lender's  Applicable  Lending
Office for the Loan,  Letter of Credit or other  amount in respect of which such
payment is made.  Except as  provided in clause  (ii) of the  provisions  of the
definition  of  Interest  Period,  if the due  date of any  payment  under  this
Agreement,  any Note or any other Loan Document  would  otherwise  fall on a day
which is not a Business  Day such date shall be extended to the next  succeeding
Business Day and interest shall be payable for any principal so extended for the
period of such extension.

         Section 4.02 Pro Rata Treatment.  Except with respect to Bid Rate Loans
made by any Lender,  as set forth in Sections  2.03(a)(ii) or Section 5.07(b) or
to the extent otherwise provided herein: (a) (i) each borrowing from the Lenders
under  Section  2.01 shall be made from the  Lenders  in such  amounts as may be
necessary  so that,  after  giving  effect to such  borrowing,  the  outstanding
Conventional  Loans shall have been made pro rata by the Lenders  based on their
respective  Commitment  Percentages  as then in  effect,  (ii) each  payment  of
Facility Fee or other fees under Sections  2.04(a) and (b) shall be made for the
account  of the  Lenders  pro  rata  according  to their  respective  Commitment
Percentages,  and (iii)  each  termination  or  reduction  of the  amount of the
Commitments  under  Section  2.03  shall be applied  to the  Commitments  of the
Lenders pro rata according to their  respective  Global  Commitment  Percentages
(or, if there is a contemporaneous and corresponding termination or reduction of
the amount of the Canadian  Subcommitments,  such amounts as may be necessary so
that, after giving effect to such reduction,  the Global Commitment  Percentages
shall have been reduced pro rata); (b) each payment of principal of Conventional
Loans by the  Company  shall be made for the  account of the Lenders pro rata in
accordance with the respective unpaid principal amount of the Conventional Loans
held by the Lenders;  (c) each payment of interest on Conventional  Loans by the
Company shall be made for the account of the Lenders pro rata in accordance with
the  amounts  of  interest  due and  payable on such  Conventional  Loans to the
respective  Lenders;  and (d) each reimbursement by the Company of disbursements
under Letters of Credit shall be made for the account of the Lenders pro rata in
accordance with the amounts of reimbursement obligations due and payable on such
Letters of Credit to the respective Lenders. If, on any day on which payments on
account  of one or  more  Bid  Rate  Loans  are  due,  payments  on  account  of
Conventional  Loans or on account of other items  otherwise under this Agreement
are also due and the Administrative Agent has received insufficient funds to pay
all  amounts  due and owing on such date,  then the  Administrative  Agent shall
distribute  all funds so received first pro rata among the Lenders in accordance
with the unpaid  amounts due on such day, and  thereafter to the payment of such
Bid Rate Loans, pro rata.

         Section 4.03  Computations.  Interest on Eurodollar  Loans and Absolute
Rate Loans  shall be computed on the basis of a year of 360 days and actual days
elapsed  (including  the first day but excluding the last day)  occurring in the
period for which such interest is payable (unless such calculation  would result
in a rate of interest  that would exceed the Highest  Lawful Rate for any Lender
in which event such

                                      -36-

<PAGE>



calculation  for such Lender  shall be computed on the basis of a year of 365 or
366 days,  as the case may be).  Interest  on Base Rate  Loans and fees shall be
computed  on the  basis of a year of 365 or 366  days,  as the case may be,  and
actual  days  elapsed  (including  the  first  day but  excluding  the last day)
occurring in the period for which payable.

         Section 4.04 Non-receipt of Funds by the Administrative  Agent.  Unless
the  Administrative  Agent  shall have been  notified by a Lender or the Company
prior  to  the  date  on  which  a  payment  is  scheduled  to be  made  to  the
Administrative  Agent of (in the case of a Lender) the  proceeds of a Loan to be
made by it hereunder or under a Letter of Credit or (in the case of the Company)
a payment to the Administrative  Agent for account of one or more of the Lenders
hereunder (such payment being herein called a "Required Payment"),  which notice
shall be effective  upon  receipt,  that it does not intend to make the Required
Payment to the Administrative  Agent, the  Administrative  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(s)  on such date. If such Lender or the Company (as the case
may be) has not in fact made the Required Payment to the  Administrative  Agent,
the recipient(s) of such payment shall, on demand,  repay to the  Administrative
Agent the amount so made available  together with interest thereon in respect of
each day  during  the  period  commencing  on the date such  amount  was so made
available by the Administrative  Agent until the date the  Administrative  Agent
recovers  such  amount at a rate per annum  equal to the Base Rate for such day,
but in no event to exceed the Highest Lawful Rate.

         Section 4.05      Sharing of Payments, Etc.

         (a) The Company agrees that, in addition to (and without limitation of)
any right of set-off, bankers' lien or counterclaim a Lender may otherwise have,
each  Lender  shall be  entitled  (after  consultation  with the  Administrative
Agent),  at its option,  during the existence of an Event of Default,  to offset
balances held by it for account of the Company at any of its offices, in Dollars
or in any other  currency,  against any  principal of or interest on any of such
Lender's Loans or any other amount payable to such Lender hereunder or under any
other Loan  Document  which is not paid when due  (regardless  of  whether  such
balances are then due to the Company),  in which case such Lender shall promptly
notify the Company and the  Administrative  Agent  thereof,  provided  that such
Lender's failure to give such notice shall not affect the validity thereof.

         (b) If any Lender shall obtain  payment of any principal of or interest
on any Loan made by it to the  Company  under this  Agreement  or payment of any
reimbursement obligation under a Letter of Credit Agreement through the exercise
of any right of  set-off,  banker's  lien or  counterclaim  or similar  right or
otherwise,  and, as a result of such payment,  such Lender shall have received a
greater percentage of the principal or interest or reimbursement obligation then
due hereunder or under the respective  Letter of Credit  Agreement,  as the case
may be, by the Company to such Lender than the percentage  received by any other
Lenders,   such  Lender  shall   promptly   purchase  from  such  other  Lenders
participations  in (or, if and to the extent  specified by such  Lender,  direct
interests  in) the Loans made by such other Lenders (or in interest due thereon,
as the case may be) or  reimbursement  obligations  under  the  Letter of Credit
Agreements in such amounts, and make such other adjustments from time to time as
shall be  equitable,  to the end that all the Lenders shall share the benefit of
such excess payment (net of any expenses which may be incurred by such Lender in
obtaining or preserving such excess payment) pro rata in accordance

                                      -37-

<PAGE>



with the  unpaid  principal  and/or  interest  on the Loans  held by each of the
Lenders or pro rata in accordance with the unpaid reimbursement  obligation owed
to each of the  Lenders.  To such end,  all the Lenders  shall make  appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if such payment is rescinded or must  otherwise be restored.  The Company agrees
that any Lender so purchasing a participation  (or direct interest) in the Loans
made by other Lenders (or in interest due thereon, as the case may be) or in the
reimbursement  obligations  owed to the other Lenders may exercise all rights of
set-off,  bankers'  lien,  counterclaim  or similar  rights with respect to such
participation  as  fully as if such  Lender  were a  direct  holder  of Loans or
reimbursement  obligations,   as  the  case  may  be,  in  the  amount  of  such
participation. Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to  exercise,  and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of the Company.  If under any  applicable  bankruptcy,  insolvency or
other  similar law, any Lender  receives a secured claim in lieu of a set-off to
which this Section 4.05 applies,  such Lender shall, to the extent  practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.05 to share the benefits
of any recovery on such secured claim.

         (c) Without  limitation  of the last  sentence of Section  4.02,  if an
Event of Default has occurred and is continuing and the Notes have been declared
to be immediately due and payable,  the  Administrative  Agent shall  distribute
funds  received  pro rata among the Lenders in  accordance  with the  respective
unpaid principal  amounts of the Loans (whether  Conventional  Loans or Bid Rate
Loans) held by the Lenders.

         Section 4.06 Assumption of Risks.  The Company assumes all risks of the
acts or omissions of  beneficiaries of any of the Letters of Credit with respect
to its use of the Letters of Credit.  Except in the case of gross  negligence or
willful  misconduct on the part of such Person or any of its employees,  neither
the Administrative Agent, the Administrative Agent's  correspondents,  any other
Agent, nor any Lender shall be responsible:  (a) for the validity or genuineness
of certificates or other documents, even if such certificates or other documents
should in fact  prove to be  invalid,  fraudulent  or  forged;  (b) for  errors,
omissions,  interruptions or delays in transmissions or delivery of any messages
by mail, telex, or otherwise,  whether or not they be in code; (c) for errors in
translation or for errors in  interpretation  of technical terms; or (d) for any
other  consequences  arising  from  causes  beyond  the  Administrative  Agent's
control. In addition,  neither the Administrative Agent, any other Agent nor any
Lender shall be  responsible  for any error,  neglect,  or default of any of the
Administrative  Agent's correspondents which were chosen in good faith; and none
of  the  above  shall  affect,  impair  or  prevent  the  vesting  of any of the
Administrative  Agent's  rights or any  Lender's  rights or powers  hereunder or
under the Letter of Credit Agreements,  all of which rights shall be cumulative.
The  Administrative  Agent and the  Administrative  Agent's  correspondents  may
accept certificates or other documents that appear on their face to be in order,
without  responsibility  for further  investigation.  In furtherance  and not in
limitation  of the  foregoing  provisions,  the Company  agrees that any action,
inaction  or  omission  taken or not  taken by the  Administrative  Agent or any
correspondent  in the absence of gross  negligence or willful  misconduct by the
Administrative  Agent or any  correspondent  in  connection  with any  Letter of
Credit, or any related drafts, certificates,  documents or instruments, shall be
binding  on the  Company  and  shall  not put the  Administrative  Agent  or its
correspondents or any Lender under any resulting liability to the Company.

         Section 4.07      Obligation to Reimburse and to Prepay.

         (a) If any draft or claim shall be presented for payment under a Letter
of  Credit,  after  confirming  that  such  draft  or  claim  complies  with all
requirements of the relevant Letter of Credit,  the  Administrative  Agent shall
promptly  notify the  Company  and each Lender  orally  (confirming  such notice
promptly in writing) of the date and the amount of the draft or claim  presented
for payment, the Business Day on which such draft or claim is to be honored and,
in the  case  of  each  Lender,  the  ratable  share  of  such  draft  or  claim
attributable  to such Lender on the basis of its Commitment  Percentage  then in
effect.

         (b) If a  disbursement  by the  Administrative  Agent is made under any
Letter of Credit and no Default under this Agreement  shall have occurred and be
continuing, the Company may elect, and if no election is made, the Company shall
be deemed to have  elected,  to have the amount of such  disbursement  up to the
amount of the Available U.S. Commitment then available treated as a Conventional
Loan to the  Company as provided  in Section  2.01(a),  subject to the terms and
conditions set forth in this Agreement. With respect to any disbursement under a
Letter of Credit after and during the  continuance  of a Default,  the amount of
such disbursement shall be due and payable immediately and the Company shall pay
to the  Administrative  Agent,  promptly  after notice of such  disbursement  is
received by the Company,  in federal or other  immediately  available funds, the
amount of such disbursement, together with interest on the amount disbursed from
and including the date of  disbursement  until payment in full of such disbursed
amount at a varying rate per annum equal to (i) the Base Rate (as in effect from
time to time) plus the Applicable Margin for Base Rate Loans (but in no event to
exceed the Highest Lawful Rate) for the first Business Day following the date of
such  disbursement  and (ii) the  Post-Default  Rate for Base Rate Loans for the
period from and  including  the second  Business Day  following the date of such
disbursement  to and including  the date of repayment in full of such  disbursed
amount.

         (c) The  Company's  obligation  to make  each  such  payment  shall  be
absolute  and  unconditional  and  shall not be  subject  to any  defense  or be
affected by any right of setoff,  counterclaim  or recoupment  which the Company
may now or hereafter have against any  beneficiary of any Letter of Credit,  the
Administrative  Agent,  any other Agent,  any Lender or any other Person for any
reason whatsoever (but,  without prejudice to any other provisions  hereof,  any
such payment shall not waive, impair or otherwise adversely affect any claim, if
any,  that the Company may have against any  beneficiary  of a Letter of Credit,
the Administrative Agent, any other Agent, any Lender or any other Person).

         (d) If an Event of Default shall have occurred and be  continuing,  the
Company shall, upon request of the Majority Lenders,  pay to the Paying Agent as
cash collateral an amount equal to the LC Exposure.  The Company's obligation to
provide such cash collateral shall be absolute and unconditional  without regard
to whether any  beneficiary  of any such Letter of Credit has  attempted to draw
down all or a portion of such amount  under the terms of a Letter of Credit.  In
addition,  the  Company's  obligation  shall not be subject to any defense or be
affected by a right of setoff,  counterclaim or recoupment which the Company may
now or hereafter have against any such beneficiary, any Agent, any Lender or any
other  Person for any reason  whatsoever  (but,  without  prejudice to any other
provisions  hereof,  any such  payment  shall not  waive,  impair  or  otherwise
adversely  affect any claim,  if any,  that the  Company  may have  against  any
beneficiary of a Letter of Credit,  the  Administrative  Agent, any other Agent,
any Lender or any other Person).  The Company hereby grants to the Paying Agent,
for the benefit of the Agents and the Lenders,  a security  interest in all such
cash to secure the LC Exposure and any and all other Indebtedness now or

                                      -39-

<PAGE>



hereafter owing  hereunder.  If the Company shall provide cash collateral  under
this Section 4.07 or shall prepay any Letter of Credit  pursuant to Section 2.08
and thereafter either (i) drafts or other demands for payment complying with the
terms of such Letters of Credit are not made prior to the respective  expiration
dates  thereof,  or (ii) such Event of Default  shall have been waived or cured,
then  the  Agents  and the  Lenders  agree  that  the  Paying  Agent  is  hereby
authorized,  without further action by any other Agent or Lender, to release the
Lien in such  cash and will  direct  the  Paying  Agent to remit to the  Company
amounts for which the contingent obligations evidenced by such Letters of Credit
have ceased.

         Section 4.08      Obligations for Letters of Credit.

         (a)  Immediately,  (i) upon  issuance  of any  Letter  of Credit by the
Administrative  Agent and (ii) effective on the date of the Initial Funding with
respect to Letters of Credit  outstanding  under the Prior Credit  Agreements on
the date of Initial  Funding,  each Lender  shall be deemed to be a  participant
through the Administrative  Agent in the obligation of the Administrative  Agent
under  such  Letter  of  Credit.  Upon  the  delivery  by  such  Lender  to  the
Administrative  Agent of funds requested for a disbursement  pursuant to Section
4.08(c),  such  Lender  shall be  deemed  as having  purchased  a  participating
interest in the Company's reimbursement  obligations with respect to such Letter
of Credit in an  amount  equal to such  funds  delivered  to the  Administrative
Agent.

         (b) Each Lender severally agrees with the Administrative  Agent and the
Company that it shall be  unconditionally  liable to the  Administrative  Agent,
without regard to the occurrence of any Default or Event of Default, for its pro
rata share,  based upon its Commitment  Percentage,  of disbursements  under any
Letter of Credit, and agrees to reimburse on demand the Administrative Agent for
its pro rata share of each such disbursement.

         (c) The  Administrative  Agent shall promptly  request from each Lender
its  ratable  share of any  disbursement  under any  Letter  of Credit  that the
Company has not elected  hereunder to treat as a  Conventional  Loan pursuant to
Section  4.07,  which  amount  shall be made  available  by each  Lender  to the
Administrative  Agent at the Principal Office in immediately  available funds no
later than 2:00 p.m.  Houston time on the date requested.  If such amount due to
the Administrative  Agent is made available later than 2:00 p.m. Houston time on
the date requested,  then such Lender shall pay to the Administrative Agent such
amount with interest thereon in respect of each day during the period commencing
on the date such amount was requested  until the date the  Administrative  Agent
receives  such  amount  at a rate per  annum  equal to the Base Rate (but not to
exceed the Highest Lawful Rate).

         Section 5.01      Additional Costs.

         (a)  Eurodollar  Regulations.  The Company  shall pay  directly to each
Lender such amounts as such Lender may  determine to be necessary to  compensate
it for any increased  costs incurred by the Lender which such Lender  determines
are  attributable  to its  making or  maintaining  any  Eurodollar  Loans or its
obligation  to make any  Eurodollar  Loans  hereunder,  or any  reduction in any
amount  receivable  by such Lender  hereunder in respect of any of such Loans or
such obligation (such increases in costs and

reductions  in amounts  receivable  being  herein  called  "Additional  Costs"),
resulting from any Regulatory Change which: (i) changes the basis of taxation of
any amounts  payable to such Lender under this Agreement or its Notes in respect
of any of such Loans (other than franchise taxes,  taxes on capital and/or gross
receipts  or taxes  imposed on the  overall  net income of such Lender or of its
Applicable  Lending  Office for any of such Loans by the  jurisdiction  in which
such  Lender  has  its  principal  office  or  such  Applicable  Lending  Office
("Excluded Taxes"));  or (ii) imposes or modifies any reserve,  special deposit,
minimum  capital,   capital  ratio  or  similar  requirements  relating  to  any
extensions  of  credit  or  other  assets  of,  or any  deposits  with or  other
liabilities  of,  such  Lender  (including  any of such  Loans  or any  deposits
referred to in the definition of "Eurodollar  Rate" in Section 1.02 hereof),  or
any Commitment of such Lender;  or (iii) imposes any other  condition  affecting
this Agreement or its Notes (or any of such extensions of credit or liabilities)
or Commitment.

          (b)   Suspension  of  Eurodollar   Loans.   If  any  Lender   requests
compensation from the Company under Section 5.01(a),  the Company may, by notice
to such Lender (with a copy to the Administrative Agent), suspend the obligation
of such Lender to make  additional  Loans of the Type with respect to which such
compensation  is  requested  until the  Regulatory  Change  giving  rise to such
request  ceases to be in effect (in which case the  provisions  of Section  5.04
shall be applicable). Without limiting the effect of the foregoing provisions of
this Section 5.01(b), in the event that, by reason of any Regulatory Change, any
Lender  either (i) incurs  Additional  Costs  based on or measured by the excess
above a  specified  level of the  amount  of a  category  of  deposits  or other
liabilities  of such Lender  which  includes  deposits by reference to which the
interest rate on Eurodollar Loans is determined as provided in this Agreement or
a category of extensions of credit or other assets of such Lender which includes
Eurodollar Loans or (ii) becomes subject to restrictions on the amount of such a
category of liabilities or assets which it may hold, then, such Lender may elect
by notice to the Company (with a copy to the  Administrative  Agent), to suspend
its obligation to make additional  Eurodollar Loans until such Regulatory Change
ceases to be in effect (in which case the  provisions  of Section  5.04 shall be
applicable).

         (c) Capital  Adequacy.  Without  limiting the effect of Section 5.01(a)
and (b), but without duplication, after any Regulatory Change, the Company shall
pay directly to each Lender such amounts as such Lender may reasonably determine
to be necessary as a result of such Regulatory  Change to compensate such Lender
(or its  parent or  holding  company)  for any  costs  which it  determines  are
attributable to the maintenance by such Lender (or its parent or holding company
or its Applicable  Lending  Office) of its capital in respect of its Commitment,
its Note, any Loans and/or any interest held by it in any Letter of Credit. Such
compensation shall include, without limitation, an amount equal to any reduction
of the rate of return on assets  or  equity of such  Lender  (or any  Applicable
Lending  Office) to a level  below that  which  such  Lender (or any  Applicable
Lending   Office)   could   have   achieved   but  for  such  law,   regulation,
interpretation, directive or request.

         Section 5.02 Limitation on Eurodollar Loans.  Notwithstanding any other
provision  of this  Agreement,  if,  on or  prior  to the  determination  of any
Eurodollar Rate for any Interest Period:

         (a) the Administrative  Agent determines (which  determination shall be
conclusive,  absent  manifest  error) that  quotations of interest rates for the
relevant  deposits referred to in the definition of "Eurodollar Rate" in Section
1.02  are not  being  provided  in the  relevant  amounts  or for  the  relevant
maturities for purposes of determining rates of interest for Eurodollar Loans as
provided herein; or

                                      -41-

         (b) the Administrative Agent shall determine (which determination shall
be  conclusive,  absent  manifest  error)  that the  relevant  rates of interest
referred to in the  definition  of  "Eurodollar  Rate" in Section  1.02 upon the
basis of which the rate of  interest  for  Eurodollar  Loans  for such  Interest
Period is to be determined  are not  sufficient to adequately  cover the cost to
the Lenders of making or maintaining Eurodollar Loans;

then the  Administrative  Agent shall give the  Company  and each Lender  prompt
notice  thereof  and so long as such  condition  remains in effect,  the Lenders
shall be under no obligation to make additional  Eurodollar Loans (in which case
the provisions of Section 5.04 shall be applicable).

         Section 5.03  Illegality.  Notwithstanding  any other provision of this
Agreement,  in the  event  that  it  becomes  unlawful  for  any  Lender  or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans  hereunder,  then such Lender shall  promptly  notify the Company  thereof
(with a copy to the Administrative  Agent) and such Lender's  obligation to make
Eurodollar  Loans  shall be  suspended  until such time as such Lender may again
make and maintain Eurodollar Loans (in which case the provisions of Section 5.04
shall be applicable).

If the  obligation  of any Lender to make  Eurodollar  Loans shall be  suspended
pursuant to Section 5.01,  5.02 or 5.03 ("Affected  Loans"),  all Affected Loans
which would  otherwise be made by such Lender shall be made instead as Base Rate
Loans (and, if an event referred to in Section 5.03 has occurred and such Lender
so requests by notice to the Company  with a copy to the  Administrative  Agent,
all  Affected  Loans of such  Lender  then  outstanding  shall be  automatically
converted  into Base Rate  Loans on the date  specified  by such  Lender in such
notice).  To the extent that Affected  Loans are so made as (or converted  into)
Base Rate Loans,  all payments of principal  which would otherwise be applied to
such Lender's Affected Loans shall be applied instead to the Loans so converted.

         Section 5.05 Compensation.  The Company shall pay to the Administrative
Agent for account of each  Lender,  upon the request of such Lender  through the
Administrative  Agent,  such  amount or amounts as shall be  sufficient  (in the
reasonable  opinion  of such  Lender)  to  compensate  it for any loss,  cost or
expense which such Lender determines are attributable to:

         (a) any payment,  prepayment or conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the Loans pursuant to
Section 10.01) on a date other than the last day of the Interest Period for such
Loan; or

         (b) any  failure  by the  Company  for any  reason  (including  but not
limited to, the failure of any of the conditions  precedent specified in Article
VI to be satisfied, but excluding failures arising out of the negligence,  gross
negligence  or wilful  misconduct  of a Lender or Agent) to borrow,  continue or
convert  a  Eurodollar  Loan from  such  Lender on the date for such  borrowing,
continuation  or conversion  specified in the relevant notice of borrowing given
pursuant to Section 2.02.

Without limiting the effect of the preceding  sentence,  such compensation shall
include an amount  equal to the  excess,  if any,  of (x) the amount of interest
which otherwise would have accrued on the principal  amount so paid,  prepaid or
converted for the period from the date of such payment, prepayment or

                                      -42-

<PAGE>



conversion  to the last day of the then  current  Interest  Period for such Loan
(or,  in the case of a failure to  borrow,  convert or  continue,  the  Interest
Period for such Loan which would have  commenced on the date  specified for such
borrowing,  conversion or  continuation)  at the applicable rate of interest for
such Loan provided for herein over (y) the interest component of the amount such
Lender  would have bid in the London  interbank  market for Dollar  deposits  of
leading banks in amounts comparable to such principal amount and with maturities
comparable to such period (as reasonably determined by such Lender).

         Section 5.06      Additional Cost in Respect of Tax.

         (a)  Payments  Fee and Clear.  Each  payment to be made by the  Company
hereunder or in  connection  herewith to any Agent or Lender or any other Person
shall be made free and clear of and without  deduction  for or on account of any
Tax unless the Company is required to make such payment subject to the deduction
or withholding of Tax, in which case (except for Excluded Taxes) the sum payable
by the Company in respect of which such  deduction or withholding is required to
be made shall be  increased to the extent  necessary  to ensure that,  after the
making of such deduction or withholding,  such Person receives and retains (free
from any liability in respect of any such  deduction or  withholding)  a net sum
equal to the sum  which it would  have  received  and so  retained  had not such
deduction or withholding been made or required to be made.

         (b) Obligation to Indemnify.  If (i) any Agent or Lender is required by
law to make any payment on account of any Tax (except for Excluded  Taxes) on or
in relation to any sum received or receivable  hereunder by such Agent or Lender
or (ii) any  liability  in respect of any such  payment  is  asserted,  imposed,
levied or assessed against such Agent or Lender, then the Company shall promptly
pay to such  Agent  or  Lender,  as the  case  may be,  any  additional  amounts
necessary  to  compensate  it for  such  payment  together  with  any  interest,
penalties and expenses payable or incurred in connection therewith.  If an Agent
or a Lender  has paid over on  account of Tax  (other  than  Excluded  Taxes) an
amount paid to it by the Company pursuant to the foregoing  indemnification  and
the  amount so paid over is  subsequently  refunded  to the  recipient  Agent or
Lender,  in whole or in part,  then the recipient Agent or Lender shall promptly
remit such amount refunded to the Company.

         (c) Notice of Changes;  Proof of Payment. If at any time the Company is
required by law to make any deduction or withholding  from any sum payable by it
hereunder or in connection herewith (or if thereafter there is any change in the
rates at which or the  manner  in which  such  deductions  or  withholdings  are
calculated), the Company shall promptly notify the Administrative Agent thereof.
If the Company makes any payment  hereunder or in connection  herewith for which
it is required by law to make any  deduction  or  withholding,  it shall pay the
full  amount to be  deducted  or  withheld  to the  relevant  taxation  or other
authority  within the time allowed for such  payment  under  applicable  law and
shall deliver to the  Administrative  Agent within thirty (30) days after it has
made such  payment  to the  applicable  authority  (i) a receipt  issued by such
authority or (ii) other evidence  reasonably  satisfactory to the Administrative
Agent  evidencing the payment to such authority of all amounts so required to be
deducted or withheld from such payment.

         Section 5.07      Avoidance of Taxes and Additional Costs.

         (a) Change Applicable Funding Office. If a Lender makes any claim under
Section  5.01 or  Section  5.06 in respect of  Additional  Costs of Taxes,  such
Lender  shall be obligated  to use  reasonable  efforts to designate a different
Applicable  Lending  Office  for the  Commitment  or the  Loans  of such  Lender
affected  by such event if such  designation  will avoid the need for, or reduce
the amount of, such compensation or the imposition of any Taxes and will not, in
the sole opinion of such Lender,  be  disadvantageous  to such Lender;  provided
that such Lender shall have no obligation to so designate an Applicable  Lending
Office located in the United States.

         (b) Replacement.  If any Lender claims (i) payment of Additional Costs,
(ii) the  inability  to make or  maintain  the  Eurodollar  Rate  for its  Loans
pursuant to Section 5.01 or 5.03 (when such  inability is not then being claimed
by  substantially  all of the Lenders) or (iii) payment of any Taxes pursuant to
Section  5.06,  then the  Company  shall  have the right,  upon  payment of such
requested Additional Costs or Taxes, if applicable, to (i) prepay the Loans made
by such Lender and  terminate  the  Commitment  of such Lender on a non pro rata
basis or (ii) subject to the approval of the Administrative Agent (such approval
not to be unreasonably withheld or delayed), find one or more Persons willing to
assume the Loans,  Commitment  and other  obligations of such Lender and replace
such Lender pursuant to an Assignment and Acceptance.  Any such assumption shall
be effected  pursuant to Section 12.06(b).  The Company shall not,  however,  be
entitled  to replace  any Lender if an event which with notice or lapse of time,
or both, would constitute a Default or an Event of Default exists at the time.

         Section 5.08 Lender Tax Representation.  Each Lender represents that it
is either (a) a  corporation  organized  under the laws of the United  States of
America or any state thereof or (b) entitled to complete  exemption  from United
States  withholding  tax imposed on or with respect to any  payments,  including
fees, to be made to it pursuant to this Agreement,  the Notes and the other Loan
Documents  (i) under an  applicable  provision of a tax  convention to which the
United  States of  America  is a party or (ii)  because  it is acting  through a
branch,  agency or office in the United  States of America and any payment to be
received by it hereunder is  effectively  connected  with a trade or business in
the United States of America.  Each Lender that is not a  corporation  organized
under the laws of the United  States of America or any state  thereof  agrees to
provide to the Company and the Administrative Agent on the Effective Date, or on
the date of its delivery of the Assignment  and Acceptance  pursuant to which it
becomes a Lender,  and at such other times as required by United States law, two
accurate and complete  original signed copies of either Internal Revenue Service
Form 4224 (or  successor  form)  certifying  that all  payments to be made to it
hereunder will be effectively  connected to a United States trade or business or
Internal  Revenue  Service Form 1001 (or successor  form)  certifying that it is
entitled  to the  benefit  of a tax  convention  to which the  United  States of
America is a party which completely  exempts from United States  withholding tax
all payments to be made to it hereunder. If a Lender determines,  as a result of
any Regulatory Change or other change in its circumstances, that it is unable to
submit any form or certificate  that it is obligated to submit  pursuant to this
Section  5.08,  or that it is  required  to  withdraw or cancel any such form or
certificate  previously submitted,  it shall promptly notify the Company and the
Administrative Agent of such fact.

         Section  5.09  Limitation  on Right to  Compensation.  Any  demand  for
compensation  pursuant to Article V (other than Section 5.06) must be made on or
before six (6) months after the Lender incurs the expense, cost or economic loss
referred  to or such  Lender  shall be deemed to have  waived  the right to such
compensation.  Any demand for compensation pursuant to Section 5.06 must be made
on or before  twelve (12) months after the Lender  incurs the  expense,  cost or
economic  loss  referred  to or such  Lender  shall be deemed to have waived the
right to such compensation.

         Section  5.10  Compensation  Procedure.  Each  Lender  will  notify the
Administrative  Agent and the Company of any event  occurring  after the date of
this Agreement which will entitle such Lender to compensation or indemnification
pursuant to this Article V as promptly as practicable after it obtains knowledge
thereof and  determines to request such  compensation.  Each Lender will furnish
the  Administrative  Agent and the Company with a certificate  setting forth the
basis  and  amount  of  each  request  by  such  Lender  for   compensation   or
indemnification  and  specify  the  Section  pursuant  to which  it is  claiming
compensation  or  indemnification.  Such  certificate  shall  also  include  (i)
calculations  in reasonable  detail  computing such claim,  and (ii) a statement
from such Lender that it is asserting  its right for  indemnity or  compensation
not solely with respect to the  Indebtedness  outstanding  under this Agreement,
but is  generally  making  such  claims  with  respect to similar  borrowers  in
connection with transactions  similar to the one contemplated in this Agreement.
Determinations  and  allocations by any Lender for purposes of this Article V of
the effect of any Regulatory  Change pursuant to Sections  5.01(a) or (b), or of
the effect of capital  maintained  pursuant to Section 5.01(c),  on its costs or
rate of return of maintaining  Loans or issuing or  participating  in Letters of
Credit or its  obligation  to make Loans or issue or  participate  in Letters of
Credit, or on amounts  receivable by it in respect of Loans or such obligations,
and of the additional  amounts  required to compensate such Lender under Section
5.01, 5.05 or 5.06, shall be conclusive,  provided that such  determinations and
allocations are made on a reasonable basis.

                                   ARTICLE VI

Agents or special counsel to the Administrative Agent may reasonably request.

         Section 6.02      Subsequent Loans and Letters of Credit.

         (a)  Generally.  The  obligation  of the  Lenders  to make Loans to the
Company  upon the  occasion of each  borrowing  hereunder  (other than Base Rate
Loans which are made  pursuant to the terms  hereof  solely to replace  existing
Eurodollar  Loans which have matured in the normal  course on the last day of an
Interest Period  therefor or pursuant to Section 5.03) or of the  Administrative
Agent to issue Letters of Credit is subject to the further conditions  precedent
that,  as of the date of such  Loans and after  giving  effect  thereto:  (i) no
Default or Event of Default shall have occurred and be continuing; (ii) no event
or circumstance  having a Material  Adverse Effect shall have occurred since the
date of the Financial  Statements,  and (iii) the representations and warranties
made by OEI and the Company in Article VII and the Loan Documents  shall be true
in all  material  respects  on and as of the date of the making of such Loans or
the  issuance of such Letter of Credit with the same force and effect as if made
on and as of such date and following  such new borrowing or issuance,  except as
such  representations and warranties are modified to give effect to transactions
expressly  permitted  hereby or to the  extent  expressly  limited to an earlier
date.

         (b)  Certification  as to  Representations.  Each notice of  borrowing,
conversion or continuation  and selection of an Interest Period (other than Base
Rate  Loans  which are made  pursuant  to the  terms  hereof  solely to  replace
existing  Eurodollar  Loans which have matured in the normal  course on the last
day of an Interest  Period  therefor or pursuant to Section 5.03) or request for
the  issuance,  renewal,  extension or  reissuance  of a Letter of Credit by the
Company hereunder shall constitute a certification by OEI and the Company to the
effect set forth in Section  6.02(a)  (both as of the date of such  notice  and,
unless OEI or the Company otherwise notifies the  Administrative  Agent prior to
the date of or immediately  following such borrowing or such issuance, as of the
date of such borrowing or issuance, as the case may be).

         (c)  Certificate  Regarding  Incurrence of Debt under  Indentures.  The
obligation of the Lenders to make Loans to the Company or of the  Administrative
Agent to issue Letters of Credit, if, after giving effect thereto, the aggregate
principal  amount of all the Loans then  outstanding,  the LC  Exposure  and the
Canadian  Indebtedness  would be in excess of  $100,000,000,  is  subject to the
further  condition  precedent that OEI deliver a certificate  from an authorized
officer,  in form and substance  reasonably  satisfactory to the  Administrative
Agent, certifying that, as of the date of incurrence,  OEI is permitted to incur
such  Indebtedness  or Canadian  Indebtedness  under the  Indentures and setting

         Section 6.03 Conditions  Relating to Letters of Credit.  In addition to

the issuance, renewal, extension or reissuance of the Letters of Credit referred
to in Section 2.01(b) is subject to the following conditions precedent:

         (a) At least one (1)  Business  Day prior to the date of the  issuance,

Agent shall have received a written  request for a Letter of Credit as described
in Section 2.02.

         (b) The Company  shall have duly and validly  executed and delivered to
the Administrative  Agent a Letter of Credit Agreement  pertaining to the Letter
of Credit.

                                   ARTICLE VII
                         Representations and Warranties

         OEI and the Company represent and warrant to the Agents and the Lenders
as follows:

         Section 7.01 Corporate Existence. OEI, the Company, UMC Canada and each
Restricted Subsidiary: (a) is duly organized and validly existing under the laws
of the  jurisdiction  of its  formation  (or,  if  appropriate,  the laws of the
jurisdiction under which it is continued);  (b) has all requisite power, and has
all material  governmental  licenses,  authorizations,  consents  and  approvals
necessary  to own its assets and carry on its  business as now being  conducted;
and (c) is qualified to do business in all  jurisdictions in which the nature of
the  business  conducted  by it makes  such  qualification  necessary  and where
failure so to qualify would have a Material Adverse Effect.

         Section 7.02      Financial Condition.

         (a) The  unaudited  pro  forma  combined  balance  sheet of OEI and its
Consolidated  Subsidiaries  as  at  December  31,  1997,  consolidated  for  the
preceding  fiscal year of OEI and United  Meridian,  which is  presented to give
effect to the Merger under the pooling of  interests  method of  accounting,  as
reflected in SEC Form S-4, and the related  consolidated  statement of income of
OEI and its Consolidated  Subsidiaries for the fiscal period ended on said date,
heretofore  furnished  to each of the  Lenders,  fairly  present in all material
respects  the  consolidated  financial  condition  of OEI and  its  Consolidated
Subsidiaries  and the  consolidated  results of their operations as at said date
and for the period  stated  (subject to the absence of a statement of changes in
stockholders'  equity  and  cash  flows).  OEI  believes  that  its  assumptions
contained  in  the  foregoing  unaudited  pro  forma  financial  statements  are
reasonable  for  presenting the  significant  financial and  accounting  effects
attributable  to the  Merger  in  accordance  with SEC  rules for such pro forma
financial statements.

         (b) OEI and its Consolidated Subsidiaries, as of December 31, 1997, had
no  material  events of loss or  casualties,  material  contingent  liabilities,
liabilities  for taxes,  Liens,  unusual  forward or  long-term  commitments  or
unrealized or anticipated  losses from any  unfavorable  commitments,  except as
referred  to or  reflected  or  provided  for in  the  Financial  Statements  or
otherwise  contemplated  by this Agreement.  Since December 31, 1997,  there has
been no change or event which has had or could  reasonably be expected to have a
Material Adverse Effect.


                                      -48-

<PAGE>



         Section 7.03  Litigation.  Except as disclosed on Schedule 7.03,  there
are no legal  or  arbitral  proceedings  or any  proceedings  by or  before  any
Governmental Authority, now pending or (to the knowledge of the Company and OEI)
threatened  against OEI or any of its  Restricted  Subsidiaries,  including  the
Company,  or against any of their respective  Property which could reasonably be
expected  to have a  Material  Adverse  Effect or which  would seek to enjoin or
prevent consummation of the Merger or the Operating Merger.

         Section  7.04 No Breach.  The  execution  and  delivery  by OEI and its
Restricted  Subsidiaries,  including the Company, of this Agreement,  the Notes,
the other Loan Documents, the consummation of the transactions herein or therein
contemplated,  including the Merger and the Operating Merger, and the compliance
with the terms and  provisions  hereof will not (a) conflict with or result in a
breach of, or require any consent under (i) the respective charter or by-laws of
such Person,  or (ii) any  applicable  law or  regulation,  or any order,  writ,
injunction  or  decree  of any  court or other  Governmental  Authority,  or any
agreement  or  instrument  to which any such Person is a party or by which it is
bound or to which it is subject, in each case in such manner as could reasonably
be expected to have a Material Adverse Effect; or (b) constitute a default under
any such agreement or instrument, or result in the creation or imposition of any
Lien upon any of the revenues or Property of such  Person,  in each case in such
manner as could reasonably be expected to have a Material Adverse Effect.

         Section 7.05 Corporate Action; Binding Obligation.  Each of OEI and the
Company has all necessary corporate power and authority to execute,  deliver and
perform its respective obligations under this Agreement,  the Notes and the Loan
Documents to which it is a party; and the execution, delivery and performance by
each of OEI and the Company of this Agreement,  the Notes and the Loan Documents
to which it is party have been duly authorized by all necessary corporate action
on its part. This  Agreement,  the Notes and the Loan Documents to which it is a
party constitute the legal, valid and binding obligation of each of such Person,
enforceable  against it in accordance with their terms, except as may be limited
by  applicable  bankruptcy,  insolvency,  reorganization  or other  similar laws
affecting  creditors' rights and general  principles of equity.  Each of OEI and
United  Meridian had all  necessary  corporate  power and  authority to execute,
deliver and perform its respective  obligations under the Merger Agreement;  and
the execution,  delivery and  performance by each such Person of its obligations
under the Merger  Agreement  were duly  authorized  by all  necessary  corporate
action on its part.  Each of the  Company  and UMC had all  necessary  corporate
power and  authority to perform the  transactions  contemplated  by it under the
Merger  Agreement;  and  performance  by each such  Person  of the  transactions
contemplated  by it under  the  Merger  Agreement  were duly  authorized  by all
necessary  corporate  action on its part. On or prior to the Effective Date, the
Merger and the Operating Merger have been consummated.

         Section 7.06 Approvals.  Other than (i) Approvals  heretofore obtained,
(ii) the Approvals described in the last sentence of this Section 7.06 and (iii)
Approvals  the  absence of which  could not  reasonably  be  expected  to have a
Material  Adverse Effect,  no  authorizations,  approvals or consents of, and no
filings or registrations  with, any  Governmental  Authority  ("Approvals")  are
necessary for the  execution,  delivery or  performance by OEI or the Company of
this Agreement, the Notes, the Loan Documents to which it is a party, the Merger
and the Operating Merger or for the validity or  enforceability  thereof.  It is
understood that continued performance by OEI and its Subsidiaries, including the
Company,  of this  Agreement and the other Loan  Documents to which such Persons
are a  party  will  require  various  Approvals,  such  as  filings  related  to
environmental matters, ERISA matters, Taxes and intellectual

                                      -49-

property,  filings  required to maintain  corporate  and  similar  standing  and
existence,  filings  pursuant to the Uniform  Commercial Code and other security
filings and  recordings,  filings  required by the SEC,  routine  filings in the
ordinary  course of  business,  and  filings  required  in  connection  with the
exercise by the Lenders and the Agents of remedies in  connection  with the Loan
Documents.

         Section  7.07 Use of Loans and Letters of Credit.  The  proceeds of the

development and operations of such Properties in an amount  materially in excess
of the working  interest  of such  Properties  set forth in the Initial  Reserve
Reports.  OEI  has,  or has  caused  its  Restricted  Subsidiaries  to,  pay all
royalties  payable  under the  Hydrocarbon  Interests  to which it is  operator,
except those  contested in  accordance  with the terms of the  applicable  joint

utility"  within the meaning of the Public Utility  Holding Company Act of 1935,
as amended.

neither the Company nor any of its  Restricted  Subsidiaries  have  violated any
provisions  of The Natural  Gas Act or any other  Federal or State law or any of
the regulations thereunder, including those of any Governmental Authority having
jurisdiction  over the Oil and Gas Properties of the Company or such  Restricted
Subsidiary,  which  violation  could  reasonably  be expected to have a Material

         (f) OEI or any of its Restricted  Subsidiaries,  including the Company,
may upon thirty (30) days' prior notice to the  Administrative  Agent change its
principal  place of business  and chief  executive  offices  from that listed on
Exhibit D.

         Section 8.04 Environmental  Matters. OEI shall, and shall cause each of
its Subsidiaries,  including the Company,  to promptly notify the Administrative
Agent and the Lenders in writing of any existing,  pending or threatened action,
investigation or inquiry by any  Governmental  Authority (of which OEI or any of
its  Subsidiaries  has actual  knowledge) in connection  with any  Environmental
Laws,  excluding  routine testing and corrective  action,  which would involve a
violation of any  Environmental Law or remedial  obligation  (individually or in
the aggregate) sufficient to have a Material Adverse Effect.

         Section 8.05      Engineering Reports.

         (a) On or before March 15 of each year  commencing  March 15, 1999, the
Company shall furnish to the Technical  Agents and the Lenders a Reserve  Report
as of the preceding January 1st in form and substance reasonably satisfactory to
the  Technical  Agents.  The  January  1 Reserve  Report  of each year  shall be
comprised  of two reports;  one being  prepared by or under the  supervision  of
certified   independent  petroleum  engineers  or  other  independent  petroleum
consultant(s)  reasonably  acceptable to the Technical Agents and evaluating Oil
and Gas  Properties  comprising  not less than eighty  percent  (80%) of the SEC
Value of the Oil and Gas Properties of OEI and its Restricted Subsidiaries which
Properties  OEI desires to have  included in the Borrowing  Base,  and the other
being prepared by or under the  supervision of the chief  petroleum  engineer of
OEI (utilizing substantially similar procedures to those used by its independent
petroleum  engineers) and  evaluating the Oil and Gas Properties  comprising the
remaining  SEC  Value of the Oil and Gas  Properties  of OEI and its  Restricted
Subsidiaries  which  Properties  OEI desires to have  included in the  Borrowing
Base.  Notwithstanding  the foregoing,  the January 1 Reserve Report relating to
any Oil and Gas  Properties  not located in the  geographical  boundaries of the
United States of America and Canada and surrounding  waters shall be prepared by
certified   independent  petroleum  engineers  or  other  independent  petroleum
consultant(s) reasonably acceptable to the Technical Agents.

         (b) On or before  September 15 of each year  commencing  September  15,
1998,  the  Company  shall  furnish to the  Technical  Agents and the  Lenders a
Reserve  Report  prepared as of the  immediately  preceding  July 1 by the chief
engineer of the Company (who shall  certify such report to have been prepared in
accordance  with the  procedures  used in the  immediately  preceding  January 1
Reserve  Report),  which  shall  further  evaluate  the Oil  and Gas  Properties
evaluated in the  immediately  preceding  Reserve  Report.  For any  unscheduled
redetermination  pursuant to Section  2.09(d),  the Company  shall  provide such
Reserve  Report (which shall be prepared by its chief  engineer) with an "as of"
date as specified by the Required Lenders, as soon as possible, but in any event
no later than 75 days following the receipt of the request by the Administrative
Agent.

         (c) With the  delivery  of each  Reserve  Report  required  in  Section
8.05(a) and (b), the Company shall provide to the Lenders a statement reflecting
(i) any  material  changes in the net revenue  interest of each well or lease as
reflected in the Reserve  Report  delivered for the prior  period,  after giving
effect to all  encumbrances  listed  therein  from the net revenue  interests as
reflected  in  such  report,  along  with  an  explanation  as to  any  material
discrepancies between the two net revenue interest disclosures,  and (ii) except
as set forth on an exhibit thereto,  on a net basis there are no gas imbalances,
take or pay or

                                      -58-

<PAGE>



other prepayments with respect to their Oil and Gas Properties evaluated in such
Reserve  Report  which  would  require  the  Company  or any  of its  Restricted
Subsidiaries to deliver  Hydrocarbons  produced from such Oil and Gas Properties
at some future time without then or thereafter receiving full payment therefor.

         (d) If the  Technical  Agents desire to exclude an Oil and Gas Property
included  in the  Borrowing  Base on the  basis  that  title to such Oil and Gas
Property  is  unsatisfactory,  the  Administrative  Agent shall give OEI written
notice thereof and OEI shall have 90 days to cure such defect.  If OEI is unable
to cure any such title defect  requested  to be cured within the 90-day  period,
such default shall not be a Default or an Event of Default,  but instead, if the
aggregate  value of all such Oil and Gas  Properties  which have  unsatisfactory
title defects (and which have not  previously  resulted in the invocation of the
remedy set forth in this  Section)  constitutes  5% or more of the then  current
amount of the  Borrowing  Base,  the Technical  Agents shall have the right,  by
sending written notice to OEI, to reduce the then outstanding  Borrowing Base by
an amount as  reasonably  determined  by the  Technical  Agents to  reflect  the
impairment to the Borrowing Base caused by such title defect. This adjustment to
the  Borrowing  Base shall become  effective  immediately  after receipt of such
notice.

         Section 8.06 Stock of  Restricted  Subsidiaries.  Except as provided in
Section 9.08 and Exhibit D, OEI will at all times own all issued and outstanding
shares  of all  classes  of stock of its  Restricted  Subsidiaries  as listed on
Exhibit  D and the  Company  will at all times own all  issued  and  outstanding
shares of all classes of stock of its Restricted  Subsidiaries listed on Exhibit
D.

         Section  8.07  Further  Assurances.  OEI  shall,  and  shall  cause its
Restricted  Subsidiaries  to,  cure  promptly  any defects in the  creation  and
issuance of the Notes and the  execution  and  delivery  of the Loan  Documents,
including this  Agreement.  OEI and its Restricted  Subsidiaries,  including the
Company,   will  at  their   expense   promptly   execute  and  deliver  to  the
Administrative  Agent  upon  request  all  such  other  and  further  documents,
agreements  and  instruments  (a) in compliance  with or  accomplishment  of the
covenants and agreements of OEI and the Company in the Loan Documents, including
this Agreement,  (b) to further evidence and more fully describe the collateral,
if any,  intended as security for the Notes, (c) to correct any omissions in the
Loan Documents,  or more fully state the security  obligations set out herein or
in any of the Loan  Documents,  (d) to perfect,  protect or  preserve  any Liens
created pursuant to any of the Loan Documents, or (e) to make any recordings, to
file any notices, or obtain any consents, all as may be necessary or appropriate
in connection therewith.

         Section 8.08 Performance of Obligations. The Company will pay the Notes
according to the reading, tenor and effect thereof; and OEI and the Company will
and will cause each  Subsidiary to do and perform every act and discharge all of
the  obligations to be performed and discharged by them under this Agreement and
the other Loan Documents, at the time or times and in the manner specified.

                                   ARTICLE IX
                               Negative Covenants

in effect and until payment in full of all Loans hereunder, all interest thereon
and all  other  amounts  payable  by OEI or the  Company  hereunder  or any Loan
Document:

<PAGE>



anything or permit  anything to be done which will subject any such  Property to
any  remedial  obligations  under any  Environmental  Laws if the effect of such
violation could  reasonably be expected to have a Material  Adverse Effect.  OEI

of the Majority Lenders:

         (a)  defease,  redeem,  offer  to  purchase  or  purchase  any  of  the
Subordinated  Debt or the  Long-Term  Pari Passu Debt,  unless the  Indebtedness

instrument  evidencing or guaranteeing  the  Subordinated  Debt or the Long-Term
Pari Passu Debt;  provided that the foregoing  shall not apply to the following:
(i) any amendment, supplement or modification,  that, subject to the concurrence
of the Administrative  Agent, the Syndication Agent and the Documentation Agent,

generally less restrictive than its terms  immediately  prior thereto,  (ii) any
amendment or  supplement  to the 96 Indenture or the 97 Indenture to conform the
provisions  thereof to the  corresponding  provisions of the 95  Indenture;  and
(iii) OEI and the  Company  (and the  trustee,  if  applicable)  may enter  into
supplemental indentures to the instruments

                                      -68-

exists or would  result  from such  creation  or  designation,  including  under
Section  9.03(p),   (iii)  such  Subsidiary  owes  or  incurs  Debt  other  than
Non-Recourse  Debt, Debt under Section 9.01(j),  and Debt owed to OEI and any of
its Restricted  Subsidiaries in connection with  investments,  loans or advances
(including, without limitation,  contingent obligations) made in compliance with
Section 9.03(n) or (p), or (iv) such creation or designation shall result in the
creation  or  imposition  of any  claim  or  Lien  on any  assets  of OEI or any
Restricted Subsidiary.  Notwithstanding the foregoing, in no event may the Board
of  Directors  of  OEI  designate  the  Company,  Norfolk  or UMC  Canada  as an
Unrestricted Subsidiary.

         (b) Without  limitation of Section 9.21(a),  OEI will not, and will not

Restricted  Subsidiary;  provided,  however,  the prior  written  consent of the
Majority Lenders shall not be required to (i) change the  characterization of an
Unrestricted Subsidiary to a Restricted Subsidiary if (A) no Default or Event of
Default  shall have  occurred  and be  continuing  at such time or would  result
therefrom,  (B) after  giving  effect to such  re-characterization,  each of the
representations and warranties made by OEI and the Company in the Loan Documents
to which each is a party shall be true and correct in all material respects, and
(C) OEI provides the  Administrative  Agent five (5) days advance written notice
of  its  intent  to   re-characterize   such   Subsidiary  or  (ii)  change  the
characterization of a Restricted Subsidiary to an Unrestricted Subsidiary if (A)
no Default or Event of Default  shall have  occurred and be  continuing or would
result therefrom (including a violation of Section 9.03(p)),  and on the date of
such  recharacterization,  all investments  made by OEI or any other  Restricted
Subsidiary   in  such   Restricted   Subsidiary   prior  to  the  date  of  such
re-characterization  shall be investments in an Unrestricted  Subsidiary subject
to  Section  9.03(p),  (B) if the  Restricted  Subsidiary  owns  any Oil and Gas
Properties which are included in the Borrowing Base, the Borrowing Base shall be
reduced by an amount  reasonably  determined at the time by the Technical Agents
to reflect the  contribution  to the Borrowing  Base of the Properties so owned,
and (C) OEI provides  the  Administrative  Agent five (5) days  advance  written
notice of its intent to re-characterize such Subsidiary.

         Section 9.22 Gas Imbalances,  Take-or-Pay or Other Prepayments. OEI and

which warrant production of Hydrocarbons

                                      -69-

<PAGE>



and will not hereafter  allow gas imbalances,  take-or-pay or other  prepayments
with  respect  to  the  Oil  and  Gas  Properties  of  OEI  and  its  Restricted
Subsidiaries which would require OEI or such Restricted  Subsidiaries to deliver
Hydrocarbons produced on Oil and Gas Properties at some future time without then
or thereafter receiving full payment therefor to exceed 10,000,000 mcf of gas in
the aggregate on a net basis.

and all other amounts payable by the Company hereunder and under the Notes shall
become automatically  immediately due and payable without  presentment,  demand,
protest,  notice of  intent  to  accelerate,  notice  of  acceleration  or other
formalities  of any  kind,  all of which  are  hereby  expressly  waived  by the
Company.

         Section  10.02 Cash  Collateral  for Letters of Credit.  If an Event of
Default exists, the  Administrative  Agent and the Paying Agent may, or upon the
request of the Majority  Lenders,  shall,  proceed to enforce remedies under the

of any cash proceeds from any disposition of the  collateral,  all such cash and
cash proceeds shall be applied as set forth in the Intercreditor Agreement.

                                   ARTICLE XI
                                   The Agents

powers as are specifically delegated to it by the terms of this Agreement or any
Loan  Document,  together  with such other powers as are  reasonably  incidental
thereto.  (As of the  Effective  Date,  the  Co-Agents  have been  delegated  no
specific powers or  responsibilities  under this  Agreement.)  Each Agent (which
term as used in this  sentence  and in Section  11.05 and the first  sentence of
Section  11.06 shall  include  reference to its  Affiliates  and its own and its
Affiliates' officers, directors, employees and agents): (a) shall have no duties
or  responsibilities  except those expressly set forth in this Agreement and the
other Loan Documents and shall not by reason of this Agreement or any other Loan
Document  be a  trustee  for  any  other  Agent  or  Lender;  (b)  shall  not be
responsible  to any  other  Agent or the  Lenders  (i) for the  accuracy  of any
recitals, statements,  representations or warranties contained in this Agreement
or any Loan  Document or in any  certificate  or other  document  referred to or
provided for in, or received by any of them under, this Agreement;  (ii) for the
value, validity,  effectiveness,  genuineness,  enforceability or sufficiency of
this Agreement,  any Note or any Loan Document or any other document referred to
or  provided  for herein;  or (iii) for any  failure by OEI,  the Company or any
other  Person to perform any of its  obligations  hereunder or  thereunder;  (c)
shall not be  required  to initiate  or conduct  any  litigation  or  collection
proceedings  hereunder except as may be expressly  required under this Agreement
or any other  Loan  Document;  and (d) shall not be  responsible  for any action
taken or omitted to be taken by it hereunder  or under any other Loan  Document,
except for its own gross negligence or willful misconduct. The Agents may employ
agents and  attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it in good faith.
Each  Agent may deem and treat the payee of any Note as the holder  thereof  for
all  purposes  hereof  unless and until a written  notice of the  assignment  or
transfer thereof shall have been filed with the Administrative  Agent,  together
with the written consent of the Company to such assignment or transfer.

         Section 11.02 Reliance by Agents. Each Agent shall be entitled to rely:
(a) upon any certification, notice or other communication (including any thereof
by telephone, telex, telegram or cable) believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or Persons;
and (b) upon advice and statements of legal counsel, independent accountants and
other  experts  selected  by any  Agent in good  faith.  As to any  matters  not
expressly provided for by this Agreement or any Loan Document,  each Agent shall
in all  cases be fully  protected  in  acting,  or in  refraining  from  acting,
hereunder in accordance with instructions  signed by the Majority  Lenders;  and
such instructions of the Majority Lenders and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders.

         Section 11.03  Defaults.  No Agent shall be deemed to have knowledge of
the  occurrence  of a Default  (other  than,  in the case of the  Administrative
Agent,  the  non-payment  of principal of or interest on Loans or of fees or the
non-payment  of  reimbursement  obligations  of the Company in  connection  with
Letters of Credit)  unless it has  received  notice  from either a Lender or the
Company  specifying  such  Default and stating  that such notice is a "Notice of
Default".  In the event that any Agent  receives such a notice of the occurrence
of a Default,  it shall  promptly  give notice to the  Administrative  Agent who
shall thereafter give prompt notice thereof to the Lenders.

         Section 11.04 Rights as a Lender.  With respect to its  Commitment  and
the Loans made by it and the  Letters  of Credit  issued by it or in which it is
participating, each Agent (and any successor acting as an Agent) in its capacity
as a Lender  hereunder  shall have the same rights and powers  hereunder  as any
other Lender and may exercise the same as though it were not acting as an Agent,
and the term "Lender"

                                      -73-

<PAGE>



or "Lenders"  shall include each Agent in its  individual  capacity.  Each Agent
(and any successor acting as an Agent) and its Affiliates may (without having to
account  therefor to any other Agent or Lender) accept deposits from, lend money
to and generally engage in any kind of banking, trust or other business with OEI
and its Subsidiaries, including the Company, or any of OEI's Affiliates as if it
were not acting as an Agent.  Each Agent and its  Affiliates may accept fees and
other  consideration  from OEI or any of its Affiliates,  including the Company,
for services in connection with this  Agreement,  any Loan Document or otherwise
without having to account for the same to any other Agent or the Lenders.

         Section  11.05  Indemnification.  The Lenders  agree to indemnify  each
Agent (to the extent not reimbursed  under Section 12.03,  but without  limiting
the obligations of the Company under Section 12.03),  ratably in accordance with
the aggregate principal amount of the Loans made by the Lenders (or, if no Loans
are at the  time  outstanding,  ratably  in  accordance  with  their  respective
Commitments),  for  any  and  all  Indemnity  Matters  of any  kind  and  nature
whatsoever  which may be imposed on, incurred by or asserted  against such Agent
in any way  relating to or arising out of: (a) this  Agreement or any other Loan
Document or the transactions contemplated hereby and thereby (including, without
limitation,  the costs and expenses  which the Company is obligated to pay under
Section 12.03 but  excluding,  unless a Default has occurred and is  continuing,
normal  administrative  costs and expenses  incident to the  performance  of its
agency duties  hereunder);  or (b) the enforcement of any of the terms hereof or
of any other  Loan  Document;  provided  that no Lender  shall be liable for any
Indemnity  Matter to the extent it arises from the gross  negligence  or willful
misconduct of the Person to be indemnified;  and provided further that no Lender
shall be liable for any  Indemnity  Matters  arising  solely by reason of claims
among the Agents and their shareholders.  THE FOREGOING INDEMNITIES SHALL EXTEND
TO THE INDEMNIFIED PARTIES  NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF
EVERY  KIND OR  CHARACTER  WHATSOEVER,  WHETHER  ACTIVE OR  PASSIVE,  WHETHER AN
AFFIRMATIVE  ACT OR AN  OMISSION,  INCLUDING  WITHOUT  LIMITATION,  ALL TYPES OF
NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE
OF THE  INDEMNIFIED  PARTIES OR BY REASON OF STRICT  LIABILITY  IMPOSED  WITHOUT
FAULT  ON ANY ONE OR MORE OF THE  INDEMNIFIED  PARTIES.  TO THE  EXTENT  THAT AN
INDEMNIFIED PARTY IS FOUND BY A FINAL,  NON-APPEALABLE JUDGMENT OF A COURT OR BY
AGREEMENT TO HAVE  COMMITTED AN ACT OF GROSS  NEGLIGENCE  OR WILFUL  MISCONDUCT,
THIS  CONTRACTUAL  OBLIGATION OF  INDEMNIFICATION  SHALL CONTINUE BUT SHALL ONLY
EXTEND TO THE PORTION OF THE CLAIM THAT IS DEEMED TO HAVE  OCCURRED BY REASON OF
EVENTS OTHER THAN THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF THE PARTY SEEKING
INDEMNIFICATION.  IN ADDITION,  THE FOREGOING  INDEMNITIES EXCLUDE ALL INDEMNITY
MATTERS ARISING SOLELY BY REASON OF CLAIMS AMONG  INDEMNIFIED  PARTIES AND THEIR
SHAREHOLDERS.

         Section 11.06  Non-Reliance  on Agents and other  Lenders.  Each Lender
agrees: (a) that it has,  independently and without reliance on any Agent or any
other  Lender,  and based on such  documents  and  information  as it has deemed
appropriate, made its own credit analysis of OEI and its Subsidiaries, including
the Company,  and decision to enter into this  Agreement;  and (b) that it will,
independently and without reliance upon any Agent or any other Lender, and based
on such  documents and  information  as it shall deem  appropriate  at the time,
continue to make its own analysis and  decisions in taking or not taking  action
under this Agreement or any other Loan  Document.  No Agent shall be required to
keep itself  informed as to the performance or observance by OEI, the Company or
any other  Person of its  obligations  under  this  Agreement  or any other Loan
Document  or  document  referred  to or  provided  for herein or to inspect  the
Properties or books of OEI and its Subsidiaries, including the Company. Except

                                      -74-

<PAGE>



for notices,  reports and other documents and information  expressly required to
be furnished to the Lenders by an Agent  hereunder or under a Loan Document,  no
Agent shall have any duty or responsibility to provide any other Agent or Lender
with any credit or other information concerning the affairs, financial condition
or business of OEI and its Subsidiaries, including the Company, (or any of their
Affiliates)  which may come into the  possession  of such  Agent or any of their
Affiliates.

         Section  11.07  Action by Agents.  Except  for action or other  matters
expressly required of an Agent hereunder, such Agent shall in all cases be fully
justified  in failing or refusing to act  hereunder  unless it shall (i) receive
written  instructions  from the  Majority  Lenders  specifying  the action to be
taken,  and (ii) be indemnified to its  satisfaction  by the Lenders against any
and all liability  and expenses  which may be incurred by it by reason of taking
or continuing  to take any such action,  and such  instructions  of the Majority
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of  the  Lenders.  If a  Default  has  occurred  and is  continuing,  the
Administrative  Agent  shall take such action  with  respect to such  Default as
shall be directed by the  Majority  Lenders in the  written  instructions  (with
indemnities)  described in this Section 11.07,  provided that,  unless and until
the Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be  obligated  to) take such  action,  or refrain  from
taking such action,  with respect to such Default as it shall deem  advisable in
the  best  interests  of  the  Lenders.   In  no  event,   however,   shall  the
Administrative Agent be required to take any action which exposes it to personal
liability  or which is  contrary to this  Agreement  and the Loan  Documents  or
applicable law.

         Section  11.08  Resignation  or  Removal  of  Agents.  Subject  to  the
appointment  and  acceptance  of a successor  Agent as provided in this  Section
11.08,  any Agent may resign at any time by giving notice thereof to the Lenders
and the  Company,  and any Agent may be removed at any time,  for cause,  by the
Required  Lenders.  Upon any such resignation or removal,  the Required Lenders,
with the  consent  of the  Company  (which  consent  shall  not be  unreasonably
withheld or delayed),  shall have the right to appoint a successor  Agent. If no
successor  shall have been so appointed  by the Required  Lenders and shall have
accepted  such  appointment  within 30 days after  either the  retiring  Agent's
giving of notice of resignation or the Required Lenders' removal of the retiring
Agent,  then the  retiring  Agent may,  on behalf of the  Lenders,  appoint  its
successor.  Upon the acceptance of any  appointment  as an Agent  hereunder by a
successor,  such successor shall thereupon succeed to and become vested with all
the rights, powers, privileges and duties of the retiring Agent and the retiring
Agent shall be discharged from its duties and obligations  hereunder.  After any
retiring  Agent's  resignation  or removal  hereunder,  the  provisions  of this
Article XI shall  continue  in effect for its  benefit in respect of any actions
taken or omitted to be taken by it while it was acting as an Agent.

                                   ARTICLE XII
                                  Miscellaneous

         Section 12.01 Waiver. No failure on the part of any Agent or any Lender
to exercise,  no delay in exercising,  and no course of dealing with respect to,
any right,  power or privilege  under this  Agreement or any Loan Document shall
operate as a waiver  thereof;  and no single or partial  exercise  of any right,
power or privilege  under this Agreement or any Loan Document shall preclude any
other or further exercise  thereof or the exercise of any other right,  power or
privilege.  The remedies provided herein are cumulative and not exclusive of any
remedies provided by law.

consummated,  pay all  reasonable  expenses of the  Administrative  Agent in the
administration  (both before and after the execution hereof and including advice
of counsel as to the  rights  and  duties of the  Agents  and the  Lenders  with
respect  thereto) of, and in  connection  with the  negotiation,  investigation,
preparation,  execution and delivery of, recording or filing of, preservation of
rights under,  enforcement of, and  refinancing,  renegotiation or restructuring
of, this  Agreement,  the Notes and the other Loan  Documents and any amendment,

reasonable fees and disbursements of counsel for the Administrative Agent and in

against  any and all  present  and  future  stamp and other  similar  taxes with
respect to the  foregoing  matters and save each Agent and Lender  harmless from
and against any and all liabilities  with respect to or resulting from any delay
or omission to pay such taxes; and

         (c) INDEMNIFY THE AGENTS AND EACH LENDER,  THEIR  OFFICERS,  DIRECTORS,
EMPLOYEES,   REPRESENTATIVES,   AGENTS   AND   AFFILIATES   (COLLECTIVELY,   THE
"INDEMNIFIED  PARTIES") FROM, HOLD EACH OF THEM HARMLESS AGAINST,  PROMPTLY UPON
DEMAND PAY OR REIMBURSE EACH OF THEM FOR, AND REFRAIN FROM CREATING OR ASSERTING
AGAINST  ANY OF  THEM,  ANY AND ALL  INDEMNITY  MATTERS  OF ANY  KIND OR  NATURE
WHATSOEVER  WHICH MAY BE INCURRED BY OR ASSERTED  AGAINST OR INVOLVE ANY OF THEM
(WHETHER  OR NOT ANY OF THEM IS  DESIGNATED  A PARTY  THERETO)  AS A RESULT  OF,
ARISING OUT OF OR IN ANY WAY RELATED TO (I) OFFSETS, REDUCTIONS,  REBATEMENTS OR
OTHER CLAIMS,  COUNTERCLAIMS  OR DEFENSES OF ANY NATURE  WHATSOEVER  (INCLUDING,

OR  HEREAFTER  ARISING,  IN  CONNECTION  WITH  OTHER  LENDERS  WHOSE DEBT MAY BE
REFINANCED  WITH ANY  PROCEEDS OF THE LOANS (IN THEIR  CAPACITY AS LENDERS OR AS
AGENT  FOR THE  LENDERS  IN  CONNECTION  WITH THE  LOAN  DOCUMENTS  EXECUTED  IN
CONNECTION  WITH SUCH  REFINANCED  DEBT AND NOT  OTHERWISE),  THE LOAN DOCUMENTS
EXECUTED IN CONNECTION WITH SUCH REFINANCED DEBT OR ANY ACTIONS OR RELATIONSHIPS

LIMITATION,  THE  REASONABLE  FEES AND  DISBURSEMENTS  OF COUNSEL  AND ALL OTHER
EXPENSES  INCURRED IN CONNECTION WITH  INVESTIGATING,  DEFENDING OR PREPARING TO

ARISING  SOLELY  BY  REASON  OF  CLAIMS  AMONG  INDEMNIFIED  PARTIES  AND  THEIR

<PAGE>



Sections  2.03,  2.09 or 12.04 shall be  effective  without the express  written
consent of all Lenders and the Canadian Lenders; (c) no amendment,  modification
or waiver which  amends or modifies the  definition  of  "Applicable  Margin" or
reduces the interest  rate (other than as a result of waiving the  applicability
of any  post-Default  increases in such rates),  modifies the payment  dates for
payments of either principal or interest on any Loan,  modifies any fees payable
hereunder,   increases  the  Borrowing   Base  or  releases  or  modifies  OEI's

obligations or fees of any Agent shall be effective  without the consent of such
Agent.

         Section 12.05  Successors and Assigns.  This Agreement shall be binding
upon and  inure to the  benefit  of the  parties  hereto  and  their  respective
successors and permitted assigns.

         Section 12.06     Assignments and Participations.

         (a) The  Company  may not assign its rights or  obligations  hereunder,
under the  Notes or under any  Letter  of  Credit  Agreement  without  the prior
consent of all of the Lenders and the Administrative Agent.

         (b) Each  Lender may,  upon the written  consent of the Company and the
Administrative Agent which consent shall not be unreasonably withheld or delayed
(provided  that  if  an  Event  of  Default  has  occurred  and  is  continuing,
assignments may be made hereunder without the Company's consent),  assign to one
or more  assignees  all or a portion of its rights  and  obligations  under this
Agreement  pursuant to an Assignment and Acceptance  Agreement  substantially in
the form of Exhibit G (an  "Assignment and  Acceptance");  provided that (i) any
such assignment  shall be in the aggregate  amount of at least  $5,000,000,  the
entire amount of a Lender's Commitment,  if less, or such other lesser amount to
which  the  Company  has  consented,  and (ii)  the  assignee  shall  pay to the
Administrative  Agent a processing and recordation fee of $3,500;  provided that
such fee shall not be  payable in  conjunction  with any  assignments  occurring
within 30 days of the Effective Date. Any such assignment will become  effective
upon the  issuance  by the  Administrative  Agent of a letter of  acknowledgment
reflecting such assignment and the resultant  effects thereof on the Commitments
of the  assignor and  assignee,  and the  principal  amount  outstanding  of the
Conventional Loans owed to the assignor and assignee,  the Administrative  Agent
hereby  agreeing to effect such  issuance no later than five (5)  Business  Days
after its  receipt of an  Assignment  and  Acceptance  executed  by all  parties
thereto.  Promptly after receipt of an Assignment and Acceptance executed by all
parties thereto,  the  Administrative  Agent shall send to the Company a copy of
such  executed  Assignment  and  Acceptance.   Upon  receipt  of  such  executed
Assignment and Acceptance,  the Company,  will, at its own expense,  execute and
deliver  new  Conventional  Loan  Notes  to the  assignor  and/or  assignee,  as
appropriate, in accordance with their respective interests as they appear on the
Administrative  Agent's letter of acknowledgment.  Upon the effectiveness of any
assignment pursuant to this Section, the assignee will become a "Lender," if not
already a  "Lender,"  for all  purposes  of this  Agreement  and the other  Loan
Documents.  Subject  to the terms of  Section  12.10 of this  Agreement  and the
Sections referred to therein,  the assignor shall be relieved of its obligations
hereunder  to the  extent of such  assignment  (and if the  assigning  Lender no
longer holds any rights or  obligations  under this  Agreement,  such  assigning
Lender shall cease to be a "Lender"  hereunder).  The Administrative  Agent will
prepare on the last  Business Day of each month during which an  assignment  has
become effective

                                      -78-

<PAGE>



pursuant  to this  Section  12.06(b),  a new  Annex I giving  effect to all such
assignments  effected during such month,  and will promptly  provide the same to
the Company and each of the Lenders.  If an assignment is made to a Person which
had not previously been a Lender,  the Company will promptly execute and deliver
to such Lender a Bid Rate Note as described in Section 2.07(b).

         (c) Each Lender may transfer,  grant or assign participations in all or
any part of such Lender's interests hereunder pursuant to this subsection to any
Person,  provided that: (i) such Lender shall remain a "Lender" for all purposes
of this Agreement and the transferee of such participation  shall not constitute
a "Lender" hereunder; and (ii) no participant under any such participation shall
have rights to approve any amendment to or waiver of this  Agreement,  the Notes
or any Loan  Document  except to the extent such  amendment  or waiver would (x)
extend  the  Termination  Date,  (y)  reduce  the  principal  amount of any Loan
outstanding  , the  interest  rate  (other  than  as a  result  of  waiving  the
applicability  of  any  post-default   increases  in  interest  rates)  or  fees
applicable  to any of the  Commitments  or Loans in which  such  participant  is
participating,  or postpone the payment of any thereof,  or (z) release OEI from
its  obligations  under  the  Guaranty  Agreement.  In  the  case  of  any  such
participation, the participant shall not have any rights under this Agreement or
any of the Loan Documents (the participant's  rights against the granting Lender
in respect of such  participation  to be those set forth in the  agreement  with
such Lender creating such participation), and all amounts payable by the Company
hereunder shall be determined as if such Lender had not sold such participation,
provided that if such participant has made and complied with the representations
contained  in  Section  5.08,  such  participant  shall be  entitled  to receive
additional  amounts  under  Article  V on the same  basis as if it were a Lender
other  than  amounts  paid by reason of such  participant's  noncompliance  with
Section  5.08.  In addition,  each  agreement  creating any  participation  must

Sky" laws of any state.

         (e) The Lenders may furnish any  information  concerning the Company in

         (f) Notwithstanding anything in this Section 12.06 to the contrary, any
Lender may assign and pledge all or any of its Notes to any Federal Reserve Bank
or the United States Treasury as collateral security pursuant to Regulation A of
the Board of Governors of the Federal Reserve System and any operating  circular
issued by such Federal  Reserve System and/or such Federal Reserve Bank. No such
assignment and/or pledge shall release the assigning and/or pledging Lender from
its obligations hereunder.

         Section  12.07  Invalidity.  In the  event  that any one or more of the
provisions  contained in the Notes, this Agreement or in any other Loan Document

OR  HEREAFTER  HAVE TO THE  BRINGING  OF ANY SUCH ACTION OR  PROCEEDING  IN SUCH
RESPECTIVE  JURISDICTIONS.  THIS SUBMISSION TO JURISDICTION IS NONEXCLUSIVE  AND

OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

         Section  12.14  Confidentiality.  Each Lender and each Agent agree that
they will use their best  efforts  not to  disclose  without  the prior  written
consent of the Company (other than to their employees, auditors or counsel or to
another  Lender if the Lender or such Lender's  holding or parent company or the
Administrative  Agent  in its sole  discretion  determines  that any such  party
should have access to such  information)  any information with respect to OEI or
any of its Subsidiaries,  including the Company,  which is furnished pursuant to
this  Agreement  and which is  designated  by the Company to the Lenders and the
Administrative  Agent in writing as  confidential,  provided that any Lender and
the  Administrative  Agent may disclose any such  information  (a) as has become
generally  available to the public, (b) as may be required or appropriate in any
report,  statement or testimony  submitted  to any  municipal,  state or Federal
regulatory body having or claiming to have  jurisdiction over such Lender or the
Administrative  Agent or to the  Federal  Reserve  Board,  the  Federal  Deposit
Insurance Company,  National  Association of Insurance  Commissioners or similar
organizations  (whether in the United States or elsewhere) or their  successors,
(c) as may be required or  appropriate in response to any summons or subpoena or
in connection with any  litigation,  (d) in order to comply with any law, order,
regulation or ruling applicable to such Lender or the Administrative  Agent, and
(e) to the prospective  transferee in connection with any contemplated  transfer

         Section 12.15 Interest.  It is the intention of the parties hereto that
each Agent and Lender shall  conform  strictly to usury laws  applicable  to it.
Accordingly, if the transactions contemplated hereby would be usurious as to any
Agent or Lender under laws  applicable to it  (including  the laws of the United
States of America  and the State of Texas or any other  jurisdiction  whose laws
may be mandatorily  applicable to such Agent or Lender notwithstanding the other
provisions of this Agreement),  then, in that event, notwithstanding anything to
the  contrary in the Notes,  this  Agreement or any other Loan  Document,  it is
agreed as follows:  (a) the  aggregate of all  consideration  which  constitutes
interest  under law  applicable to any Agent or Lender that is  contracted  for,
taken,  reserved,  charged or received by such Agent or Lender  under the Notes,
this Agreement or under any of the other  aforesaid Loan Documents or agreements
or otherwise in connection  with the Notes shall under no  circumstances  exceed
the maximum  amount  allowed by such  applicable  law,  and any excess  shall be
canceled  automatically  and if theretofore paid shall be credited by such Agent
or Lender on the principal  amount of the  Indebtedness  (or, to the extent that
the  principal  amount of the  Indebtedness  shall have been or would thereby be
paid in full,  refunded by such Agent or Lender to the Company);  and (b) in the
event that the maturity of the Notes is  accelerated by reason of an election of
the holder  thereof  resulting from any Event of Default under this Agreement or
otherwise,  or in the event of any required or permitted  prepayment,  then such
consideration  that  constitutes  interest  under law applicable to any Agent or
Lender may never include more than the maximum amount allowed by such applicable
law, and excess  interest,  if any,  provided for in this Agreement or otherwise
shall be canceled  automatically  by such Agent or Lender as of the date of such
acceleration or prepayment and, if theretofore  paid,  shall be credited by such
Agent or Lender on the principal amount of the  Indebtedness  (or, to the extent
that the principal amount of the  Indebtedness  shall have been or would thereby
be paid in full, refunded by such Agent or Lender to the Company). All sums paid
or  agreed  to be paid to any  Agent  or  Lender  for the  use,  forbearance  or
detention of sums due hereunder shall, to the extent permitted by law applicable
to such Agent or Lender, be amortized, prorated, allocated and spread throughout
the term of the Loans  evidenced by the Notes until  payment in full so that the
rate or amount of  interest on account of any Loans or other  amounts  hereunder
does not exceed the maximum  amount  allowed by such  applicable  law. If at any
time and from time to time (i) the  amount of  interest  payable to any Agent or
Lender on any date shall be computed at the Highest  Lawful Rate  applicable  to
such Agent or Lender  pursuant to this Section  12.15 and (ii) in respect of any
subsequent interest  computation period the amount of interest otherwise payable
to such  Agent or Lender  would be less than the amount of  interest  payable to
such Agent or Lender  computed at the Highest  Lawful  Rate  applicable  to such
Agent or Lender,  then the amount of interest payable to such Agent or Lender in
respect of such  subsequent  interest  computation  period shall  continue to be
computed at the Highest Lawful Rate applicable to such Agent or Lender until the
total  amount of interest  payable to such Agent or Lender shall equal the total
amount of  interest  which would have been  payable to such Agent  Lender if the
total amount of interest had been computed without giving effect to this Section
12.15.

         To the extent that the Texas  Credit  Title is relevant to any Agent or
Lender for the purpose of determining  the Highest Lawful Rate,  each such Agent
and Lender  hereby  elects to determine  the  applicable  rate ceiling under the
Texas Credit Title by the weekly rate ceiling from time to time in effect.

         Section 12.16  Effectiveness.  This  Agreement  and the Loan  Documents
shall not be effective until the date (the  "Effective  Date") that each of them
is delivered to the Administrative  Agent in the State of Texas, and accepted by
the Administrative Agent in such State.

         Section 12.17  Release of Liens and  Guaranties  Securing  Prior Credit
Agreements.  Each Agent and Lender hereby authorizes the Administrative Agent or
its Affiliate, The Chase Manhattan Bank, in its capacity as administrative agent
under the Prior Credit  Agreements,  on behalf of each such Agent or Lender, to:
(a) execute the Master Release,  in substantially  the form of Exhibit H hereto,
together with any and all releases of Liens,  termination  statements  and other
instruments  required or  requested  thereunder;  (b) indorse in blank,  without
recourse  or  warranty,  any  instruments  previously  endorsed to the order the
Administrative  Agent or its Affiliate and delivered to it as collateral for the
obligations  under  either Prior Credit  Agreement;  (c) return any  instrument,
including stock certificates,  previously  delivered to the Administrative Agent
or its  Affiliates as collateral for the  obligations  under either Prior Credit
Agreement;  and (d) take any other  actions  reasonably  requested by OEI or the
Company  pursuant to the terms of the Master  Release which is not  inconsistent
with  the  terms  thereof.  Subject  to the  terms  of the  Master  Release,  in
substantially  the form  attached  hereto as  Exhibit  H, each  Agent and Lender
hereby  releases,  terminates  and  discharges  the Liens,  guarantees and other
obligations  described in the Master  Release as being  released,  terminated or
discharged thereby and acknowledges that such release, termination and discharge
shall be and is evidenced by its  execution of this  Agreement and the execution
by the Administrative Agent or its Affiliate of the Master Release.

         Section 12.18 Survival of Obligations.  To the extent that any payments
on the Indebtedness or proceeds of any collateral are subsequently  invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee,  debtor in possession,  receiver or other Person under any bankruptcy
law, common law or equitable  cause,  then to such extent,  the  Indebtedness so
satisfied  shall be revived and  continue as if such payment or proceeds had not
been received and the Paying Agent's (held for the benefit of the Agents and the
Lenders)  Liens (if any),  rights,  powers and remedies under this Agreement and
each Loan Document shall continue in full force and effect.  In such event, each
Loan Document shall be  automatically  reinstated and OEI shall, and shall cause
the Company and each of its Restricted  Subsidiaries to, take such action as may
be reasonably  requested by the  Administrative  Agent and the Lenders to effect
such reinstatement.

         Section 12.19 Debt  Characterization for Indenture Purposes;  Specified
or Designated Senior Indebtedness.

         (a) If so designated by OEI in its internal records (which  designation
may be made in its sole and absolute  discretion),  any Debt incurred  hereunder
and under  the  Canadian  Credit  Agreement  and all  guarantees  thereof  shall
constitute  "Indebtedness"  other than  "Permitted  Indebtedness"  or "Permitted
Subsidiary  Indebtedness"  (as such  terms are  defined in the  Indentures)  for
purposes of any Indenture.

         (b)      OEI and the Company hereby acknowledges and declares that:

                  (i) this  Agreement and the Notes and the  obligations  of OEI
         and the Company hereunder and thereunder are "Senior  Indebtedness" and
         "Specified Senior Indebtedness" and "Guarantor Senior Indebtedness" and
         "Specified Guarantor Senior Indebtedness",  respectively, under and for
         purposes of the 95 Indenture;

                  (ii) this  Agreement and the Notes and the  obligations of OEI
         and the Company hereunder and thereunder are "Senior  Indebtedness" and
         "Designated Senior Indebtedness" and "Guarantor Senior

                                      -83-

         Indebtedness"   and   "Designated   Guarantor   Senior   Indebtedness",
         respectively, under and for purposes of the 96 Indenture; and

         (iii) this  Agreement and the Notes and the  obligations of OEI and the
         Company   hereunder  and  thereunder  are  "Senior   Indebtedness"  and
         "Designated  Senior  Indebtedness" and "Guarantor Senior  Indebtedness"
         and "Designated Guarantor Senior Indebtedness", respectively, under and
         for purposes of the 97 Indenture;

         and that as such,  the  Lender  Group is  entitled  to the  rights  and
         privileges  afforded holders of Senior  Indebtedness,  Specified Senior
         Indebtedness  or  Designated  Senior  Indebtedness,   Senior  Guarantor
         Indebtedness,  Specified  Guarantor  Senior  Indebtedness or Designated
         Guarantor Senior Indebtedness under each of the Indentures.

         Section 1.03 Credit Agreement  Definitions.  Unless  otherwise  defined

                                   ARTICLE II
                                  THE GUARANTY

         Section 2.01 Obligations  Guaranteed.  The Guarantor hereby irrevocably
and   unconditionally   guarantees   the  prompt  payment  at  maturity  of  the
Obligations.

         Section  2.02  Nature  of  Guaranty.  This  guaranty  is  an  absolute,
irrevocable,  completed and continuing guaranty of payment and not a guaranty of
collection,  and no notice of the Obligations or any extension of credit already
or  hereafter  contracted  by or extended  to the  Company  need be given to the
Guarantor.  This guaranty may not be revoked by the Guarantor and shall continue
to be effective  with respect to debt under the  Obligations  arising or created
after any  attempted  revocation by the Guarantor and shall remain in full force
and effect until the Obligations are paid in full and the Aggregate  Commitments
are  terminated,  notwithstanding  that  from  time to  time  prior  thereto  no
Obligations  may be  outstanding.  The  Company,  the Agents and the Lenders may
modify, alter, rearrange,  extend for any period and/or renew from time to time,
the  Obligations and the Agents and the Lenders may waive any Defaults or Events
of Default  without notice to the Guarantor and in such event the Guarantor will
remain  fully bound  hereunder on the  Obligations.  Subject to the terms of the
Credit Agreement,  this Guaranty  Agreement may be enforced by the Agents and/or
the  Lenders  and any  subsequent  holder  of the  Obligations  and shall not be
discharged by the assignment or  negotiation of all or part of the  Obligations.
The  Guarantor   hereby  expressly  waives   presentment,   demand,   notice  of
non-payment,  protest  and notice of protest  and  dishonor,  notice of Event of
Default,  notice of intent to accelerate the maturity and notice of acceleration
of the maturity and any other notice in  connection  with the  Obligations,  and
also notice of acceptance of this Guaranty Agreement,  acceptance on the part of
the Agents and the Lenders being conclusively presumed by their request for this
Guaranty Agreement and delivery of the same to the Administrative Agent.

         Section  2.03  Lenders'  Rights.  Subject  to the  terms of the  Credit
Agreement,  the Guarantor authorizes the Lenders (or the Administrative Agent on
behalf of the  Lenders),  without  notice or demand and  without  affecting  the
Guarantor's obligation hereunder,  to take and hold agreed-upon security for the
payment of the Obligations,  and exchange,  enforce,  waive and release any such
security;  and to apply  such  security  and  direct the order or manner of sale
thereof as the Agents and the Lenders in their discretion may determine;  and to
obtain a guaranty  of the  Obligations  from any one or more  Persons and at any
time or times to enforce, waive, rearrange, modify, limit or release any of such
other Persons from their obligations under such guaranties.

         Section 2.04  Guarantor's  Waivers.  The Guarantor  waives any right to
require  the Agents and the  Lenders to (a)  proceed  against the Company or any
other Person liable on the  Obligations,  (b) enforce  their rights  against any
other guarantor of the Obligations,  (c) proceed or enforce their rights against
or exhaust any security  given to secure the  Obligations,  (d) have the Company
joined with the Guarantor in any suit

                                        3

arising out of this Guaranty Agreement and/or the Obligations, or (e) pursue any
other remedy whatsoever. Neither the Agents nor the Lenders shall be required to
mitigate  damages  or  take  any  action  to  reduce,  collect  or  enforce  the
Obligations.  The  Guarantor  waives  any  defense  arising  by  reason  of  any
disability,  lack of  corporate  authority  or power,  or other  defense  of the
Company or any other  guarantor  of the  Obligations,  and shall  remain  liable
hereon  regardless  of whether the Company or any other  guarantor  be found not
liable thereon for any reason.

         Section 2.05 Maturity of  Obligations;  Payment.  The Guarantor  agrees
that  if the  maturity  of the  Obligations  is  accelerated  by  bankruptcy  or
otherwise,  such maturity  shall also be deemed  accelerated  for the purpose of
this Guaranty Agreement without demand or notice to the Guarantor. The Guarantor
will,  forthwith  upon notice  from the  Administrative  Agent of the  Company's
failure to pay the Obligations at maturity,  pay to the Administrative Agent for
the  benefit  of the  Agents  and  the  Lenders  at the  Administrative  Agent's
Principal  Office,  the  amount  due and unpaid by the  Company  and  guaranteed
hereby. The failure of the Administrative Agent to give this notice shall not in
any way release the Guarantor hereunder.

         Section  2.06  Lenders'  Expenses.  If the  Guarantor  fails to pay the
Obligations after notice from the Administrative  Agent of the Company's failure
to pay any Obligations at maturity  (whether by acceleration or otherwise),  and
if the Agents or the Lenders  obtain the services of an attorney for  collection
of amounts  owing by the  Guarantor  hereunder,  or obtain  advice of counsel in
respect of any of their  rights  under this  Guaranty  Agreement,  or if suit is
filed to enforce  this  Guaranty  Agreement,  or if  proceedings  are had in any
bankruptcy,  receivership or other judicial proceedings for the establishment or
collection  of any amount  owing by the  Guarantor  hereunder,  or if any amount
owing by the  Guarantor  hereunder is collected  through such  proceedings,  the
Guarantor agrees to pay to the Administrative  Agent at its Principal Office the
reasonable attorneys' fees of the Agents and the Lenders.

         Section 2.07 Obligation.  It is expressly agreed that the obligation of
the  Guarantor  for the payment of the  Obligations  guaranteed  hereby shall be
primary and not secondary.

         Section 2.08 Events and  Circumstances  Not Reducing or Discharging the
Guarantor's Obligations. The Guarantor hereby consents and agrees to each of the
following to the fullest extent  permitted by law,  agrees that its  obligations
under this  Guaranty  Agreement  shall not be  released,  diminished,  impaired,
reduced or  adversely  affected by any of the  following,  and waives any rights
(including without limitation rights to notice) which it might otherwise have as
a result of or in connection with any of the following:

         (a)  Modifications,  etc.  Any  renewal,  extension,  modification,  or
increase  in the  amount  of  the  Aggregate  Commitments  as in  effect  on the
Effective Date, decrease,  alteration or rearrangement of all or any part of the
Obligations,  any  Loan  Document  or  any  instrument  executed  in  connection
therewith,  or any  contract or  understanding  between the  Company,  any Agent
and/or the Lenders, or any other Person, pertaining to the Obligations;

         (b)  Adjustment,  etc.  Any  adjustment,   indulgence,  forbearance  or
compromise  that might be  granted or given by the Agents or the  Lenders to the
Company, the Guarantor or any Person liable on the Obligations;

         (c)  Condition  of  the  Company  or  the  Guarantor.  The  insolvency,
bankruptcy, arrangement,  reorganization,  adjustment, composition, liquidation,
disability,  dissolution or lack of power of the Company or the Guarantor or any
other  Person  at any  time  liable  for  the  payment  of all  or  part  of the
Obligations; or

                                        4

         (k) Other Actions  Taken or Omitted.  Any other action taken or omitted
to be taken with respect to the Credit  Agreement  or the other Loan  Documents,
the Obligations,  or the security and collateral  therefor,  whether or not such
action or omission prejudices the Guarantor or increases the likelihood that the
Guarantor will be required to pay the Obligations  pursuant to the terms hereof;
it being the  unambiguous  and  unequivocal  intention of the Guarantor that the
Guarantor  shall be obligated to pay the Obligations  when due,  notwithstanding
any occurrence,  circumstance,  event, action, or omission  whatsoever,  whether
contemplated  or  uncontemplated,  and whether or not otherwise or  particularly
described herein,  except for the full and final payment and satisfaction of the
Obligations.

and the Aggregate Commitments terminated, the Guarantor hereby waives any claim,
right or remedy which the  Guarantor may now have or hereafter  acquire  against
the Company which arises out of this Guaranty  Agreement or from the performance
by the Guarantor hereunder,  including without limitation,  any claim, remedy or
right  of   subrogation,   reimbursement,   exoneration,   indemnification,   or
participation in any such claim, right or remedy of any other Person against the
Company. The Guarantor further waives any benefit of any right to participate in
any security now or hereafter held by the Agents and/or the Lenders.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         Section  3.01 By the  Guarantor.  In order to induce the Agents and the
Lenders to accept this Guaranty Agreement, the Guarantor represents and warrants
to the Lender  Group  (which  representations  and  warranties  will survive the
creation of the Obligations and any extension of credit thereunder) that:

         (a) Benefit to the Guarantor.  The Company is a wholly-owned Subsidiary
of the  Guarantor;  and the  Guarantor's  guaranty  pursuant  to  this  Guaranty
Agreement  reasonably may be expected to benefit,  directly or  indirectly,  the
Guarantor;  and the Guarantor  has  determined  that this Guaranty  Agreement is
necessary  and  convenient  to the  conduct,  promotion  and  attainment  of the
business of the Guarantor and the Company.

         (b)  Solvency.  It (i) is not  insolvent as of the date hereof and will
not be  rendered  insolvent  as a  result  of  this  Guaranty  Agreement  or the
transactions  contemplated by the Credit Agreement or the making of the Loans or
issuance of Letters of Credit thereunder, (ii) is not engaged in a business or a
transaction,  or about to engage in a business or a  transaction,  for which any
Property or assets remaining with the Guarantor  constitutes  unreasonably small
capital,  and (iii) does not intend to incur,  or believe it will  incur,  debts
that will be beyond its ability to pay as such debts mature.

         (c) No Representation by Agents or Lenders.  Neither any Agent,  Lender
nor any other Person has made any  representation,  warranty or statement to the
Guarantor in order to induce the Guarantor to execute this Guaranty Agreement.

                                   ARTICLE IV
                          SUBORDINATION OF INDEBTEDNESS

         Section 4.01 Subordination of All Guarantor Claims. As used herein, the
term  "Guarantor  Claims" shall mean all debts and obligations of the Company to
the  Guarantor,  whether such debts and  obligations  now exist or are hereafter
incurred or arise,  or whether the  obligation be direct,  contingent,  primary,
secondary, several, joint and several, or otherwise, and irrespective of whether
such debts or  obligations  be evidenced by note,  contract,  open  account,  or
otherwise, and irrespective of the Person or

                                       6

<PAGE>



Persons in whose favor such debts or obligations may, at their  inception,  have
been, or may hereafter be created,  or the manner in which they have been or may
hereafter be acquired by the  Guarantor.  Except for  payments  permitted by the
Credit Agreement, until the Obligations shall be paid and satisfied in full, the
Aggregate  Commitments are terminated and the Guarantor shall have performed all
of its obligations  hereunder and the Loan Documents to which it is a party, the
Guarantor shall not receive or collect, directly or indirectly, from the Company
any amount upon the Guarantor Claims.

         Section  4.02  Claims  in  Bankruptcy.  In the  event of  receivership,
bankruptcy,  reorganization,  arrangement,  debtor's relief, or other insolvency
proceedings  involving the Company,  the  Administrative  Agent on behalf of the
Agents  and the  Lenders  shall  have  the  right to  prove  their  claim in any
proceeding,  so as to establish their rights hereunder and receive directly from
the receiver,  trustee or other court  custodian,  dividends and payments  which
would otherwise be payable upon Guarantor  Claims.  The Guarantor hereby assigns
such dividends and payments to the  Administrative  Agent for the benefit of the
Agents and the Lenders. Should any Agent or Lender receive, for application upon
the Obligations,  any such dividend or payment which is otherwise payable to the
Guarantor, and which, as between the Company and the Guarantor, shall constitute
a  credit  upon  the  Guarantor  Claims,  then  upon  payment  in  full  of  the
Obligations,  the Guarantor shall become  subrogated to the rights of the Agents
and the Lenders to the extent  that such  payments to the Agents and the Lenders
on  the  Guarantor  Claims  have  contributed  toward  the  liquidation  of  the
Obligations,  and such  subrogation  shall be with respect to that proportion of
the  Obligations  which would have been unpaid if the Agents and the Lenders had
not received dividends or payments upon the Guarantor Claims.

         Section 4.03 Payments Held in Trust. In the event that  notwithstanding
Sections 4.01 and 4.02, the Guarantor should receive any funds, payments, claims
or distributions which is prohibited by such Sections,  the Guarantor agrees (a)
to hold in trust for the Agents and the Lenders an amount equal to the amount of
all funds, payments,  claims or distributions so received, and (b) that it shall
have absolutely no dominion over the amount of such funds,  payments,  claims or
distributions  except to pay them promptly to the Administrative  Agent, for the
benefit of the Agents and the Lenders;  and the Guarantor  covenants promptly to
pay the same to the Administrative Agent.

         Section 4.04 Liens  Subordinate.  The Guarantor  agrees that, until the
Obligations are paid in full and the Aggregate Commitments terminated, any Liens
upon the Company's  assets securing payment of the Guarantor Claims shall be and
remain inferior and subordinate to any Liens upon the Company's  assets securing
payment of the Obligations,  regardless of whether such encumbrances in favor of
the Guarantor,  any Agent or Lender presently exist or are hereafter  created or
attach.  Without the prior  written  consent of the  Administrative  Agent,  the
Guarantor,  during the period in which any of the Obligations are outstanding or
the Aggregate  Commitments are in effect,  shall not (a) exercise or enforce any
creditor's right it may have against the Company,  or (b) foreclose,  repossess,
sequester  or  otherwise  take  steps or  institute  any  action  or  proceeding
(judicial or otherwise,  including  without  limitation the  commencement  of or
joinder  in any  liquidation,  bankruptcy,  rearrangement,  debtor's  relief  or
insolvency proceeding) to enforce any Lien, mortgages,  deeds of trust, security
interest,  collateral  rights,  judgments or other encumbrances on assets of the
Company held by the Guarantor.

         Section 4.05 Notation of Records.  All  promissory  notes and, upon the
request of the  Administrative  Agent, all accounts  receivable ledgers or other
evidence of the  Guarantor  Claims  accepted by or held by the  Guarantor  shall
contain a  specific  written  notice  thereon  that the  indebtedness  evidenced
thereby is subordinated under the terms of this Guaranty Agreement.

         Section 5.01  Successors  and Assigns.  This Guaranty  Agreement is and
shall be in every  particular  available  to the  successors  and assigns of the
Agents and the Lenders and is and shall  always be fully  binding upon the legal
representatives,  successors and assigns of the Guarantor,  notwithstanding that
some or all of the  monies,  the  repayment  of which  this  Guaranty  Agreement

reorganization or other event affecting either the Company or the Guarantor.

         Section 5.02 Notices. Any notice or demand to the Guarantor under or in
connection with this Guaranty  Agreement may be given and shall  conclusively be

address  of the  Guarantor  as  provided  for in  Section  12.02  of the  Credit
Agreement.

         Section  5.03  Authority  of   Administrative   Agent.   The  Guarantor
acknowledges that the rights and  responsibilities  of the Administrative  Agent
under  this  Guaranty  Agreement  with  respect  to  any  action  taken  by  the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option,  right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Guaranty  Agreement shall, as between
the Agents and the  Lenders,  be  governed by the Credit  Agreement  and by such
other agreements with respect thereto as may exist from time to time among them,
but, as between the Administrative  Agent and the Guarantor,  the Administrative
Agent shall be conclusively  presumed to be acting as agent for the Lenders with
full and valid  authority so to act or refrain from  acting;  and the  Guarantor
shall  not be  under  any  obligation,  or  entitlement,  to  make  any  inquiry
respecting such authority.

         Section 5.04 CONSTRUCTION.  THIS GUARANTY AGREEMENT (INCLUDING, BUT NOT
LIMITED TO, THE VALIDITY AND  ENFORCEABILITY  HEREOF)  SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.

         Section 5.05 Survival of  Obligations.  To the extent that any payments
on the Obligations or proceeds of any collateral are  subsequently  invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee,  debtor in possession,  receiver or other Person under any bankruptcy
law,  common law or equitable  cause,  then to such extent,  the  Obligations so
satisfied  shall be revived and  continue as if such payment or proceeds had not
been  received  and the  Agents'  and the  Lenders'  Liens,  rights,  powers and
remedies under this Guaranty  Agreement and each Loan Document shall continue in
full force and effect.  In such event, each Loan Document shall be automatically
reinstated  and the  Guarantor  shall  take  such  action  as may be  reasonably
requested  by  the   Administrative   Agent  and  the  Lenders  to  effect  such
reinstatement.

         Section  5.06 Subject to the  Intercreditor  Agreement.  This  Guaranty
Agreement  is  subject  to the terms of the  Intercreditor  Agreement  which (a)
subjects  the ability of the Lender  Group to pursue  remedies  hereunder to the
prior  consent of the  Canadian  Lenders  and (b) sets forth a priority  for the
application of proceeds upon any disposition of amounts received hereunder.

         Section 5.07 Status as Specified or Designated Senior Indebtedness. The
Guarantor hereby acknowledges and confirms that:

         (a)  this  Guaranty  Agreement  and the  obligations  of the  Guarantor

written instructions,  containing the appropriate indemnities,  from the Lenders
or Required Lenders as appropriate for any particular  matter,  the Paying Agent
shall have no duty to take or refrain from taking any action  unless such action

deliver to each Lender  promptly upon receipt  thereof,  duplicates or copies of
all  material  notices,  requests and other  instruments  received by the Paying
Agent under or pursuant to this Intercreditor Agreement or any Loan Document, to
the extent that the same shall not have been previously furnished to such Lender
pursuant hereto or thereto.  Promptly upon obtaining such knowledge, each Lender
agrees:  (a) to deliver to the Paying Agent,  at the same time it makes delivery
to the Obligors, a copy of any notice of default, notice of intent to accelerate
or notice of  acceleration  with  respect  to the  Indebtedness  subject to this
Intercreditor Agreement; (b) to deliver to the Paying Agent, at the same time it
makes delivery to any other Person,  a copy of any notice of the commencement of

exercise  of  remedies  with  respect  to  the  Indebtedness   subject  to  this
Intercreditor  Agreement.  The Paying Agent agrees to deliver to each Lender any
notice or other communication  received by it from any Lender pursuant to clause
(a) or (b) of this Section 2.05.

         Section  2.06  Amendments.  Amendments,   modifications,   supplements,
waivers,  consents and  approvals of or in  connection  with this  Intercreditor
Agreement or any other Loan Document  (other than the Credit  Agreements) may be
effectuated  only upon the written consent of the Required  Lenders (and, if the
rights or duties of the Paying Agent and the Agents or any Obligors are affected
thereby,  by the Paying Agent and the Agents or the applicable  Obligor,  as the
case may be).  Amendments,  modifications,  supplements,  waivers,  consents and
approvals of or in connection  with the Credit  Agreements  shall be effectuated
only in accordance with the terms contained therein.

         Section  2.07  Pro Rata  Treatment.  The  Lenders  hereby  agree  among

Event,  each Lender  shall be entitled to receive and retain for its own account
scheduled  payments or voluntary  prepayments of principal,  interest,  fees and
premium, if any, all in compliance with the Credit Agreements, and (b) after the
occurrence and during the continuance of a Triggering  Event, all Proceeds shall
be  applied by the Paying  Agent and  shared by Lenders in  accordance  with the
respective  Pro Rata Share held by each of them and in  accordance  with Section
2.03(a).  In the event that any Lender shall obtain payment after the occurrence
and during the continuance of a Triggering  Event,  whether in whole or in part,
from any source in respect of its portion of the Indebtedness, including without
limitation  payments by reason of the exercise of its right of offset,  banker's
lien, general lien or counterclaim, such Lender shall promptly pay to the Paying
Agent such amount for application in accordance with Section 2.03(a).

         Section 2.08 Voting Procedure. Notwithstanding anything to the contrary
herein,  in the Credit  Agreements  or in any other Loan  Document,  the Lenders
agree that for purposes of any provision  hereof or thereof that requires a vote
of the Required Lenders,  each Lender shall have the right to vote independently
of the other Lenders in its Group. When this Intercreditor  Agreement requires a
vote of the Required  Lenders,  the Paying Agent shall poll the Lenders in order
to determine  the vote of the  Required  Lenders (and such vote shall be binding
upon the Lenders who are not among the Required  Lenders).  The Obligors and the
Lender  Group may rely on the Paying  Agent with regard to any such vote without
any duty of further inquiry.

         Section 2.09 Triggering  Event.  The occurrence of any of the following
shall constitute a "Triggering Event":

         (a) The occurrence and continuance of an Event of Default  specified in
Sections  10.01(f),  (g), and (h) of the U.S. Credit  Agreement as it relates to
OEI, the Company or UMC Canada, or

         (b) The Paying Agent shall have received from either the Administrative
Agent,  the Canadian  Agent or the Required  Lenders,  as  appropriate,  written
advice,  which advice shall  reference  this Section 2.09,  (i) that an Event of
Default has occurred and is continuing and (ii) that the unpaid principal amount
of the Notes and all interest  accrued and unpaid  thereon have been declared to
be then due and payable.

         Section 2.10 Bankruptcy  Preferences.  If any payment actually received
by any member of the Lender Group is  subsequently  invalidated,  declared to be
fraudulent  or  preferential  or set  aside  and is  required  to be repaid to a
trustee, receiver or any other party under any bankruptcy law, state, provincial
or Federal  law,  common law, or  equitable  cause,  then the Paying Agent shall
distribute  to such  Person  from the  Balance,  exclusive  of any amount in the
Escrow Account in accordance with Section 3.03, an amount equal to such payment.
If, due to  previous  disbursements  to the  Lender  Group  pursuant  to Section
2.03(a),  the Balance  then held by the Paying  Agent is  insufficient  for such
purpose,  then each other  member of the Lender  Group  shall pay to such Person
upon demand an amount equal to a ratable  portion of such  payment  according to
the  aggregate  amounts  distributed  to each member of the Lender  Group by the
Paying Agent.

         Section  2.11  Property of  Obligors.  The  Lenders  agree that all the
provisions of this Intercreditor Agreement shall apply to any and all Properties
and rights of the  Obligors or any other  Obligor in which the Paying  Agent (in
its  capacity as such),  any Agent or any Lender at anytime  acquires a right of
set-off or Lien,  whether pursuant to the Loan Documents,  the Credit Agreements
or a judgment,  including, without limitation, real property or rights in, on or
over  real  property,  notwithstanding  any  provision  to the  contrary  in any
mortgage,  leasehold  mortgage or other document  purporting to grant or perfect
any Lien in favor of any Lender, any Agent, or the Paying Agent.

         Section  2.12  Marshalling.  The Paying  Agent shall not be required to
marshal any present or future  security for  (including  without  limitation any
collateral  described  in any of  the  Loan  Documents),  or  guaranties  of the
Indebtedness  or any part or portion  thereof,  or to resort to such security or
guaranties in any particular order; and all rights in respect of such securities
and guaranties shall be cumulative and in addition to all other rights,  however
existing or arising.  To the extent that they lawfully may, each Obligor,  Agent
and  Lender  hereby  agrees  that it will not  invoke  any law  relating  to the
marshaling of collateral  which might cause delay or impede the  enforcement  of
the Lender Group's rights under the Loan Documents or under any other instrument
evidencing any of the  Indebtedness  or under which any of the  Indebtedness  is
outstanding or by which any of the Indebtedness is secured or guaranteed.

         Section 2.13 Lender  Dealings;  Good Faith.  Nothing  contained in this
Intercreditor  Agreement  shall  prevent  either  Group of Lenders  from dealing
directly or negotiating with the other Group for any purpose, including, but not
limited  to, the  purpose of  attempting  to reach  agreement  as to any vote or
proposed vote relating to the Paying Agent's actions  hereunder,  whether or not
any  Triggering  Event or other Default or Event of Default has  occurred.  Each
U.S. Agent and U.S. Lender  covenants and agrees with and for the benefit of the
Canadian  Agent  and each  Canadian  Lender,  and the  Canadian  Agent  and each
Canadian Lender covenants and agrees with and for the benefit of each U.S. Agent
and U.S.  Lender,  that it will,  in taking any action under this  Intercreditor
Agreement  or directing  the Paying  Agent to exercise  any remedy  hereunder or
under any other Loan  Document,  take such action or make such direction in good
faith  and in a  commercially  reasonable  manner  and not for  the  purpose  of
hindering,  delaying, obstructing or preventing the exercise by the other of its
rights under the Loan Documents.

                                   ARTICLE III

Proceeds to be  distributed  pursuant to Section  2.03(a)(ii),  the Paying Agent
shall give the Lenders  notice  thereof,  and each Lender  shall within five (5)
Business  Days notify the Paying  Agent of the amount of  Indebtedness  owing to
such Lender.  Such notification shall state the amount of its Indebtedness,  how
much is then due and owing, and how much is Contingent Indebtedness. Each Lender
with Contingent Indebtedness shall describe the status of such Indebtedness.  If
requested by the Paying Agent,  each Lender shall  demonstrate  that the amounts
set forth in its notice are actually owing to such Lender to the satisfaction of
the Paying Agent.

         Section 3.02 Escrow Account.  Prior to taking any action to enforce any
Lien or remedy under any Loan Document,  or requesting  cash  collateral for the
Letters of Credit or Bankers Acceptances,  the Paying Agent shall open an escrow
account (the "Escrow  Account")  at its banking  quarters in Houston,  Texas (or
such other city where any successor may maintain  banking  quarters)  designated
the "OEI Collateral Account."

         Section  3.03  Handling  of Escrow  Account.  Upon each  receipt by the
Paying Agent of Proceeds and after payment therefrom of all items referred to in
Section 2.03(a)(i),  remaining Proceeds ("Balance") shall be applied as provided
in this Section 3.03. If at such time,  there exists any  Indebtedness  which is
contingent in amount,  including,  without limitation,  contingent amounts of LC
Exposure,  but not including the Acceptance  Exposure (such  Indebtedness  being
"Contingent  Indebtedness"),  the  Paying  Agent  shall  (with  the  information
provided  under Section  3.01)  determine  the amount of all  Indebtedness  then
outstanding, including, without limitation, Contingent Indebtedness. The Balance
shall be applied as follows:

         (a) If no Contingent Indebtedness is outstanding, then all such Balance
shall  be  applied  to repay or  prepay  the  amount  of the  Indebtedness  then
outstanding until the Indebtedness shall have been paid in full.


         (b) If there exists Contingent Indebtedness, the Paying Agent shall (i)
deposit in the Escrow  Account a portion of such Balance equal to the Contingent
Indebtedness  divided by total  Indebtedness  (until  such time as the amount on
deposit  in the  Escrow  Account  equals the  maximum  amount of the  Contingent
Indebtedness),  and (ii)  apply the  remaining  Balance  to repay or prepay  the
amount of the Indebtedness  then outstanding  until the Indebtedness  shall have
been paid in full.  Thereafter,  any further remaining Balance shall be returned
or applied as provided in Section 2.03(a)(iii).


                                        7

<PAGE>



         (c) If at any time Contingent  Indebtedness or any part thereof becomes
Indebtedness which is no longer contingent, any funds held in the Escrow Account
up to the amount (or pro rata amount  based upon the total  amount of  remaining
Contingent  Indebtedness  if the  Escrow  Amount is less than the  amount of the
remaining  Contingent  Indebtedness) of such Indebtedness which has become fixed
(or pro rata  amount  based  upon  the  total  amount  of  remaining  Contingent
Indebtedness)  shall be distributed  pro rata to the holders of such  previously
Contingent Indebtedness.  If all of the fixed Indebtedness has been paid in full
and the Paying  Agent  determines  that the amount of monies  held in the Escrow
Account exceeds the sum of the Contingent Indebtedness outstanding at such time,
such excess shall be returned or applied as provided in Section 2.03(a)(iii).

         Section 3.04 Currency Conversion. To the extent that calculations under
this  Intercreditor  Agreement  involve U.S. and Canadian currency (or any other
currency),  the Paying Agent shall, at the time of such  calculation,  determine
all amounts based on U.S.  dollars,  using a conversion  ratio (the  "Conversion
Ratio")  determined  by it in good faith (the "U.S.  $  Amount").  The amount of
distributions  of a  Lender's  Pro Rata  Share  shall be based  upon the U.S.  $
Amount,  but in the  case of a  Canadian  Lender  shall  be  distributed  in and
converted to a Canadian dollar amount calculated by using the Conversion Ratio.

                                   ARTICLE IV
                                THE PAYING AGENT

         Section 4.01 Appointment of Paying Agent. Each Lender hereby designates
Chase Bank of Texas,  National  Association  to act as the Paying  Agent for the
Lenders with respect to any collateral  pledge under any of the Loan  Documents,
the  enforcement of any Liens granted  thereunder and the collection of Proceeds
following the disposition of any such collateral.  Each Lender hereby authorizes
the Paying Agent to designate The Chase  Manhattan  Bank of Canada to act as the
agent for the Paying Agent on behalf of the Lenders with respect to the Canadian
assets under the Loan Documents.  Each Lender hereby authorizes the Paying Agent
to take such action on its behalf  under the  provisions  of this  Intercreditor
Agreement and the Loan Documents and to exercise such powers and to perform such
duties  hereunder and thereunder as are  specifically  delegated to either Chase
Bank of Texas,  National  Association,  as  Administrative  Agent,  or The Chase
Manhattan Bank of Canada,  as Canadian Agent, or required of the Paying Agent by
the terms hereof and such other powers as are reasonably incidental thereto. The
Paying Agent may perform any of its duties hereunder by or through its agents or
employees. The Paying Agent agrees to act as Paying Agent upon the express terms
and conditions contained in this Article IV.

         Section 4.02 Nature of Duties of Paying  Agent.  The Paying Agent shall
have no duties or  responsibilities,  except those  expressly  set forth in this
Intercreditor  Agreement or any Loan  Document.  The Paying Agent shall have and
may  exercise  such  powers  hereunder  and  under  the  Loan  Documents  as are
specifically  delegated  to the  Paying  Agent by the terms  hereof or to either
Chase Bank of Texas, National Association, as Administrative Agent, or The Chase
Manhattan  Bank of Canada,  as Canadian  Agent  thereunder,  together  with such
powers as are reasonably incidental thereto. Neither the Paying Agent nor any of
its directors,  officers, employees or agents shall be liable to the Lenders for
any action taken or omitted by it as such hereunder or under the Loan Documents,
unless caused solely by its or their gross negligence or willful misconduct. The
duties of the Paying Agent shall be mechanical and administrative in nature; and
the Paying  Agent  shall not have by reason of this  Intercreditor  Agreement  a
fiduciary  relationship in respect of any Lender.  Nothing in this Intercreditor
Agreement,  expressed or implied,  is intended to or shall be so construed as to
impose upon the Paying Agent any  Indebtedness in respect of this  Intercreditor
Agreement and the other Loan Documents except as expressly set forth herein.

         Section 4.03      Lack of Reliance on the Paying Agent.

         (a)  Independently  and without  reliance  upon the Paying Agent or any
other Lender, each Lender, to the extent it deems appropriate,  has made (i) its
own  independent  investigation  of the  financial  condition and affairs of the
Obligors based on such documents and information as it has deemed appropriate in
connection  with the taking or not taking of any action in connection  herewith,
and (ii) its own appraisal of the credit worthiness of the Obligors. Each Lender
also  acknowledges  that it will,  independently  and without  reliance upon the
Paying Agent or any other Person and based on such documents and  information as
it shall deem appropriate at the time, continue to make its own credit decisions
in  taking  or  not  taking  action  under  this  Intercreditor  Agreement,  the
Indebtedness  or the  Loan  Documents.  Except  as  expressly  provided  in this
Intercreditor  Agreement  and the other Loan  Documents,  the Paying Agent shall
have no duty or  responsibility,  either initially or on a continuing  basis, to
provide any Lender with any credit or other information  concerning the affairs,
financial  condition  or business of the  Obligors or any of OEI's  Subsidiaries
which may come into the  possession of the Paying Agent or any of its Affiliates
whether  now in its  possession  or in its  possession  at  any  time  or  times
hereafter; and the Paying Agent shall not be required to keep itself informed as
to the performance or observance by any Obligor of this Intercreditor Agreement,
any Loan Document or any other document referred to or provided for herein or to
inspect the Properties or books of any Obligor.

         (b) The Paying Agent shall not (i) be responsible to any Lender for any
recitals, statements, information,  representations or warranties herein, in any
Loan Document,  or in any document,  certificate  or other writing  delivered in
connection   herewith  or  therewith  or  for  the   execution,   effectiveness,
genuineness, validity, enforceability,  collectability,  priority or sufficiency
of this Intercreditor  Agreement,  the Indebtedness or the Loan Documents or the
financial  condition  of the  Obligors;  or (ii) be required to make any inquiry
concerning  the  performance  or observance  of any of the terms,  provisions or
conditions  of  this  Intercreditor  Agreement,  the  Indebtedness  or the  Loan
Documents, the financial condition of the Obligors, or the existence or possible
existence of any Default or Event of Default.

         Section 4.04 Certain  Rights of the Paying  Agent.  If the Paying Agent
shall  request  instructions  from the Lenders with respect to any act or action
(including the failure to act) in connection with this Intercreditor  Agreement,
the Indebtedness  and the Loan Documents,  the Paying Agent shall be entitled to
refrain  from such act or taking such action  unless and until the Paying  Agent
shall have received instructions from the Required Lenders pursuant to the terms
hereof;  and the Paying Agent shall not incur  liability to any Person by reason
of so refraining. Without limiting the foregoing, no Lender shall have any right
of action  whatsoever  against the Paying  Agent as a result of the Paying Agent
acting or refraining from acting under this Intercreditor  Agreement or the Loan
Documents in accordance with the written  instructions  given in accordance with
this  Intercreditor  Agreement  and such  instructions  and any action  taken or
failure to act pursuant thereto shall be binding on all the Lenders.  Except for
action expressly  required of the Paying Agent pursuant to the terms hereof, the
Paying Agent shall be fully  justified in failing or refusing to take any action
hereunder or under the Loan  Documents  unless it shall first be  indemnified to
its  satisfaction  by the Obligors or the Lenders  against any and all liability
and expense  which may be  incurred  by the Paying  Agent by reason of taking or
continuing to take any such action.  Notwithstanding any other provision of this
Article  IV or  any  indemnity  or  instructions  provided  by any or all of the
Lenders, the Paying Agent shall not be required to take any action which exposes
the  Paying   Agent  to  personal   liability  or  which  is  contrary  to  this
Intercreditor Agreement, the Loan Documents or applicable law.

         Section  4.05  Reliance  by Paying  Agent.  The Paying  Agent  shall be
entitled to rely,  and shall be fully  protected  in  relying,  upon any Note or
other  instrument  evidencing the  Indebtedness,  writing,  resolution,  notice,
statement,  certificate,  telex,  teletype  or  telecopier  message,  cablegram,
radiogram,  order or other  documentary,  teletransmission  or telephone message
believed by it to be genuine and correct and to have been  signed,  sent or made
by the proper  Person.  The Paying  Agent may  consult  with  independent  legal
counsel  (which  shall not be  counsel  for the  Obligors),  independent  public
accountants  and other  experts  selected  by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in  accordance  with the
advice of such counsel, accountants or experts.

         SECTION 4.06 PAYING AGENT'S REIMBURSEMENTS AND INDEMNIFICATION.  TO THE
EXTENT THE PAYING  AGENT IS NOT  REIMBURSED  BY THE COMPANY OR UMC CANADA,  EACH
LENDER WILL (WITHOUT DUPLICATION IN THE CASE OF A U.S. LENDER AND ITS AFFILIATED
CANADIAN LENDER)  REIMBURSE AND INDEMNIFY THE PAYING AGENT, IN PROPORTION TO ITS
GLOBAL  COMMITMENT  PERCENTAGE,  FOR AND AGAINST ANY AND ALL  INDEMNITY  MATTERS
WHICH MAY BE IMPOSED ON,  INCURRED BY OR  ASSERTED  AGAINST THE PAYING  AGENT IN
PERFORMING  ITS DUTIES  HEREUNDER  OR UNDER ANY LOAN  DOCUMENT OR  OTHERWISE  IN
CONNECTION  HEREWITH OR THEREWITH,  INCLUDING LOSSES OCCURRING FROM THE ORDINARY
AND/OR  COMPARATIVE  NEGLIGENCE OF THE PAYING  AGENT,  IN ANY WAY RELATING TO OR
ARISING OUT OF THIS  INTERCREDITOR  AGREEMENT;  PROVIDED THAT NO LENDER SHALL BE
LIABLE  FOR ANY  PORTION OF SUCH  LIABILITIES,  INDEBTEDNESS,  LOSSES,  DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING
SOLELY FROM THE PAYING AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

         Section 4.07 The Paying Agent in its Individual Capacity.  With respect
to its Indebtedness under the Credit Agreements and its Indebtedness, the Paying
Agent shall have the same rights and powers  hereunder  as any other  Lender and
may  exercise  the same as though it were not  performing  the duties  specified
herein; and the terms "Lenders", "Required Lenders", or any similar terms shall,
unless the context  clearly  otherwise  indicates,  include Chase Bank of Texas,
National Association (or any successor Paying Agent), in its individual capacity
as and to the extent it is a holder of any Note or is an Issuing Bank and not in
its  capacity as an Agent or as the Paying  Agent.  The Paying  Agent may accept
deposits  from,  lend money to,  and  generally  engage in any kind of  banking,
trust,  financial  advisory or other business with the Obligors or any Affiliate
of the Obligors as if it were not performing the duties  specified  herein,  and
may accept  fees and other  consideration  from the  Obligors  for  services  in
connection  with this  Intercreditor  Agreement and otherwise  without having to
account for the same to the Lenders.

         Section 4.08  Creditors as Owners.  The Paying Agent may deem and treat
each Lender as the owner of such Lender's  Indebtedness  for all purposes hereof
unless and until the Paying Agent is notified of a change in Lenders pursuant to
the terms of Section 12.06 of the U.S. Credit  Agreement or Section 12.03 of the
Canadian Credit Agreement, as applicable.

         Section 4.09      Successor Paying Agent.

         (a) The Paying  Agent may resign at any time by giving  sixty (60) days
prior written notice thereof to the Lender Group, the Company and UMC Canada and
may be removed at any time with cause by the Required Lenders, which resignation
or removal shall be effective upon the  appointment of a successor to the Paying
Agent. Upon any such resignation or removal, the Required Lenders shall have the
right to appoint a successor  Paying Agent. If within thirty (30) days after the
retiring Paying Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Paying Agent, no successor  Paying Agent shall have been
so appointed by the Required  Lenders and accepted such  appointment,  then, the
retiring Paying

                                       10

<PAGE>



Agent may, on behalf of the Lenders,  appoint a successor  Paying  Agent,  which
shall be a bank which maintains an office in the United States of America,  or a
commercial  bank organized  under the laws of the United States of America or of
any State thereof,  or any Affiliate of such bank, having a combined capital and
surplus of at least  $200,000,000  as of the date of its most  recent  financial
statements.

         (b) Upon the acceptance of any appointment as Paying Agent hereunder by
a successor Paying Agent, such successor Paying Agent shall thereupon succeed to
and become  vested with all the  rights,  powers,  privileges  and duties of the
retiring  Paying Agent,  and the retiring  Paying Agent shall be discharged from
its  duties  and  Indebtedness  under this  Intercreditor  Agreement.  After any
retiring Paying Agent's  resignation or removal  hereunder as Paying Agent,  the
provisions of this Intercreditor  Agreement shall inure to its benefit as to any
actions  taken or omitted to be taken by it while it was Paying Agent under this
Intercreditor Agreement.

         Section 4.10  Employment of Paying Agent and Counsel.  The Paying Agent
may  execute  any of its  duties as  Paying  Agent  hereunder  or under the Loan
Documents by or through employees,  agents, and  attorneys-in-fact and shall not
be answerable to the Lenders for the default or misconduct of any such agents or
attorneys-in-fact  selected by it with reasonable care, provided that the Paying
Agent shall always be obligated to account for moneys or securities  received by
it or its  authorized  agents.  The Paying  Agent shall be entitled to advice of
independent  counsel  concerning  all matters  pertaining  to the agency  hereby
created and its duties hereunder or under the Loan Documents.

         Section 4.11 Independent  Action.  Each Lender agrees that no Lender or
Agent other than the Paying Agent shall have any right  individually  to realize
upon any Liens granted by the Loan Documents or to otherwise enforce or exercise
any remedy in respect of the Loan Documents  (other than the right of set-off at
law or  specified  in the Credit  Agreements,  but in any event,  subject to the
terms  thereof),  it being  understood  and  agreed  that such  remedies  may be
exercised only by the Paying Agent for the ratable  benefit of the Lender Group.
Each Agent and Lender  further agrees that it shall not  individually  institute
any  judicial  action  pertaining  to the Loan  Documents  or exercise any other
remedy  (other  than the right of  set-off  at law or  specified  in the  Credit
Agreements,  but in any event, subject to the terms thereof),  pertaining to the
Loan Documents, except with the consent of the Required Lenders.

                                    ARTICLE V
                                  MISCELLANEOUS

         Section 5.01 Authority.  The parties hereto  represent and warrant that
they have all requisite  power to, and have been duly  authorized to, enter into
this Intercreditor Agreement.

         Section 5.02 Termination.  This Intercreditor Agreement shall terminate
upon  receipt  by the Paying  Agent of  evidence  satisfactory  to it of (a) the
payment (or prepayment) in full of the principal of and the premium, if any, and
interest on all  Indebtedness,  (b) the  termination  of the  Commitments in the
Credit Agreements, and (c) the termination of the Loan Documents pursuant to the
terms of the Credit Agreements.

         Section  5.03  Notices,  etc.  All  notices  and  other  communications
hereunder  shall be given in  writing  and shall be given to such  Person at its
address or  telecopy  number as set forth on the  signature  pages of the Credit
Agreements  or such other  address or telecopy  number such Person may hereafter
specify by notice to the Paying  Agent (who shall  promptly  notify the Obligors
and the other Lenders).  Each notice or other  communication  shall be effective
(a) if given by mail,  upon receipt,  (b) if given by telecopier  during regular
business  hours,  once such  telecopy  is  transmitted  to the  telecopy  number
provided in writing to the

                                       11

Paying Agent by each Lender and by each Obligor,  respectively,  or (c) if given
by any other means, upon receipt;  provided that notices to the Paying Agent are
not effective until received.

         SECTION  5.04  PAYMENT OF  EXPENSES,  INDEMNITIES,  ETC. TO THE FULLEST
EXTENT  PERMITTED BY APPLICABLE LAW, THE OBLIGORS SHALL INDEMNIFY THE AGENTS AND
THE  LENDERS  IN  ACCORDANCE  WITH THE TERMS OF THE  CREDIT  AGREEMENTS  AND THE
OBLIGORS HEREBY AGREE THAT ALL  INDEMNITIES  SET FORTH IN THE CREDIT  AGREEMENTS
SHALL  ALSO RUN IN FAVOR OF THE  PAYING  AGENT.  IF AND TO THE  EXTENT  THAT THE
INDEBTEDNESS  OF THE OBLIGORS  UNDER THIS  SECTION 5.04 OR UNDER THE  RESPECTIVE
INDEMNITY  PROVISIONS OF THE CREDIT AGREEMENTS ARE UNENFORCEABLE FOR ANY REASON,
THE OBLIGORS  HEREBY AGREE TO MAKE THE MAXIMUM  CONTRIBUTION  TO THE PAYMENT AND
SATISFACTION OF SUCH INDEBTEDNESS WHICH IS PERMISSIBLE UNDER APPLICABLE LAW. THE
OBLIGORS'  INDEBTEDNESS UNDER THIS SECTION SHALL SURVIVE ANY TERMINATION OF THIS
INTERCREDITOR AGREEMENT AND THE PAYMENT OF THE INDEBTEDNESS, BUT SHALL TERMINATE
UPON THE TERMINATION OF THE INDEMNITIES CONTAINED IN THE CREDIT AGREEMENTS.

         Section 5.05 Applicable Law. THIS INTERCREDITOR  AGREEMENT  (INCLUDING,
BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY HEREOF AND THEREOF) SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.

         Section 5.06 Entire Agreement.  The Notes, this Intercreditor Agreement
and the other  Loan  Documents  embody the entire  agreement  and  understanding
between  the  Lenders,  the  Agents and the  Obligors  and  supersede  all prior
agreements  and  understandings  between  such  parties  relating to the subject
matter hereof and thereof.  There are no unwritten oral  agreements  between the
parties.

         Section 5.07 Execution in Counterparts.  This  Intercreditor  Agreement
may be  executed in any number of  counterparts,  each of which when so executed
shall  be  deemed  to be an  original  and all of  which  taken  together  shall
constitute one and the same  agreement.  Any signature page of a counterpart may
be detached  therefrom  without  impairing  the legal  effect of the  signatures
thereon and attached to another counterpart identical in form thereto but having
attached to it one or more additional signature pages signed by other parties.

         Section  5.08  Amendment  of Defined  Instruments.  Unless the  context
otherwise  requires or unless otherwise  provided  herein,  the terms defined in
this Intercreditor  Agreement which refer to a particular agreement,  instrument
or  document  also refer to and  include all  renewals,  extensions,  increases,
modifications,  supplements,  amendments,  and  restatements  of such agreement,
instrument or document; provided that nothing contained in this section shall be
construed to authorize any such  renewal,  extension,  increases,  modification,
supplement, amendment or restatement.

         Section  5.09   References   and  Titles.   All   references   in  this
Intercreditor Agreement to Schedules,  articles, sections, subsections and other
subdivisions refer to the Schedules,  articles, sections,  subsections and other
subdivisions  of  this   Intercreditor   Agreement  unless  expressly   provided
otherwise.  Titles  appearing  at the  beginning  of any  subdivisions  are  for
convenience  only and do not constitute any part of such  subdivisions and shall
be disregarded in construing the language contained in such subdivisions.

         Section   5.10   Severability.   If  any  term  or  provision  of  this
Intercreditor Agreement shall be determined to be illegal or unenforceable,  all
other terms and provisions of this  Intercreditor  Agreement shall  nevertheless
remain  effective  and shall be  enforced  to the fullest  extent  permitted  by

         Section  5.11  Conflict  with Loan  Documents.  If there is a  conflict
between the terms and provisions contained in the Credit Agreements,  the Notes,
any instrument  evidencing the  Indebtedness or any Loan Document with the terms
and provisions  contained  herein,  the terms and  provisions  contained in this
Intercreditor Agreement shall control.

         Section  5.12  Limitation  by Law.  All  rights,  remedies  and  powers
provided  herein may be exercised  only to the extent that the exercise  thereof
does not violate any applicable  provision of law; and all the provisions hereof
are intended (a) to be subject to all  applicable  mandatory  provisions  of law
which may be controlling  and (b) to be limited to the extent  necessary so that
they will not render this  Intercreditor  Agreement or any Loan Document invalid
under the provisions of any applicable law.

         Section 5.13 Benefit of Agreement;  Limitation on Assignment. The terms
and provisions of this  Intercreditor  Agreement shall be binding upon and inure
to the benefit of the Agents and each Lender and their respective successors and
assigns. Except as stated in the last sentence of Section 2.08 hereof, the terms
and provisions of this  Intercreditor  Agreement  shall not inure to the benefit
of, nor be relied upon by, the  Obligors  or their  successors  or  assigns.  No
Lender  shall  assign,  transfer  or  sell  any  part  of  its  portion  of  the
Indebtedness,  unless in connection with such assignment, transfer or sale, such
assignee,   transferee  or  purchaser   shall  first  become  a  party  to  this
Intercreditor Agreement.

         (b) Bankers'  Acceptances - Each Lender severally  agrees, on the terms
and  conditions  of this  Agreement,  to  accept  and,  immediately  thereafter,
purchase Bankers' Acceptances from the Company from and after the Effective Date
with a  maturity  or  Interest  Period not  beyond  the  Termination  Date in an
aggregate  amount at any one time  outstanding  up to,  but not  exceeding,  the
amount  of such  Lenders'  Commitment  as then in  effect;  provided,  that  the
Acceptance  Exposure  at any one time (i) for each  Lender  shall not exceed (1)
such Lender's  Commitment  Percentage of the  Available  Canadian  Subcommitment

         (c)  Delivery  of  Bankers'   Acceptances  -  Upon  execution  of  this
Agreement,  the Company shall  deliver to each Lender bills of exchange,  in the
form for Bankers'  Acceptances  of such Lender,  executed in blank in sufficient
quantity  and  thereafter   shall,  from  time  to  time  upon  request  of  the
Administrative Agent, deliver to the Lenders further quantities of such bills of

executed in blank and delivered to each Lender shall be held in  safekeeping  in
the vault of one of each such Lender's branches.  The standard of care that each

from loss or damage  resulting  from the failure of such Lender to maintain such
standard of care.

         each "Lender" under the Prior Credit Agreement;

                  (ii) each  "Base  Rate  Loan" and each  "Bankers'  Acceptance"
         under the Prior Credit  Agreement shall be deemed to be repaid with the
         proceeds of a new Base Rate Loan under this Agreement; and

                  (iii)  the  Prior  Credit   Agreement   and  the   commitments
         thereunder  shall be superseded by this Agreement and such  commitments
         shall terminate.

         Section 2.02  Borrowings, Renewals, Conversions, and Issuances.

         (a) Borrowings.  The Company shall give the Administrative Agent (which
shall promptly  notify the Lenders)  advance  notice as hereinafter  provided of
each  Borrowing,  renewal,  and  conversion,  which shall  specify the aggregate
amount of such  Borrowing,  and the date (which shall be a Business  Day) of the
Borrowing to be borrowed,  renewed or converted, all of which must be reasonably
acceptable to the Administrative Agent, and in the case of Bankers' Acceptances,
all details of the proposed issue,  specifying the aggregate  amount of Bankers'
Acceptances  to be accepted and purchased by the Lenders and the duration of the
Interest  Period  therefor.  Promptly  following such notice the  Administrative
Agent will  notify the  Company  and the  Lenders of the  Discount  Rate for the
specified Acceptance Date.

         (b)  Minimum  Amounts.  All  Base  Rate  Loans  (as  part  of the  same
Borrowing)  shall  be in  aggregate  amounts  among  all  Lenders  of  at  least
$1,000,000 (or whole multiples thereof) or the remaining


                                        6

<PAGE>



unused portion of the Commitments. All Bankers' Acceptances (as part of the same
Borrowing)  shall be in  aggregate  amounts  among all  Lenders of not less than
$1,000,000 and in whole multiples of $100,000.

         (c) Notices,  Etc. for Loans. All Borrowings,  renewals and conversions
shall  require  advance  written  notice from the Company to the  Administrative
Agent,  in the form of Exhibit D, or such other form as may be  accepted  by the
Administrative  Agent from time to time, which in each case shall be irrevocable
and  effective  only  upon  receipt  by the  Administrative  Agent  and shall be
received  by the  Administrative  Agent not later than (i) in the case of a Base
Rate Loan,  11:00 a.m.  Toronto time on the date of such  Borrowing,  renewal or
conversion;  and (ii) in the case of Bankers'  Acceptances,  12:00 noon  Toronto
time on a day that is not less  than one (1)  Business  Day prior to the date of
such Borrowing, renewal or conversion. Not later than 12:00 noon Toronto time on
the  date  specified  for  each  Borrowing  hereunder  or each  request  for the
acceptance  and  purchase  of a  Bankers'  Acceptance,  each  Lender  shall make
available  the  amount of the Loan or the  Available  Proceeds  of the  Bankers'
Acceptance to be made by such Lender on such date to the  Administrative  Agent,
at account  number 219274  maintained by the  Administrative  Agent at The Royal
Bank of Canada,  Correspondent Banking Division, Toronto, Canada, in immediately
available  funds for the account of the Company.  The amounts so received by the
Administrative  Agent  shall,  subject  to the  terms  and  conditions  of  this
Agreement,  be  made  available  to the  Company  by  depositing  the  same,  in
immediately  available  funds,  in an account of the Company  designated  by the
Company.

         (d)  Replacement/Renewal  Acceptances.  Subject  to the  terms  of this
Agreement,  the Company may elect to cause a new replacement Bankers' Acceptance
to be issued,  accepted and purchased to replace all or any part of any Bankers'
Acceptance  at the  maturity  thereof by giving one (1) Business  Day's  advance
notice to the  Administrative  Agent of such election,  specifying the amount of
such new Bankers' Acceptance and the Interest Period therefor. In the absence of
such a timely and proper  election,  the Company shall be deemed to have elected
to convert such  Bankers'  Acceptance to a Base Rate Loan as provided in Section
2.12(b).  All or any part of any Bankers'  Acceptance may be renewed as provided
herein,  provided  that  (i) any  renewal  Bankers'  Acceptance  shall  meet all
requirements  for Bankers'  Acceptances  hereunder,  (ii) no Default  shall have
occurred  and be  continuing  and  (iii)  the  Company  shall  have  paid to the
Administrative  Agent  for  the  account  of  Lenders  an  amount  equal  to the
difference  between the amount due on the maturing  Bankers'  Acceptance and the
Available  Proceeds  of the new  Bankers'  Acceptance.  If a Default  shall have
occurred and be  continuing,  each Bankers'  Acceptance  shall be converted to a
Base Rate Loan on the last day of the Interest Period applicable  thereto unless
the  Termination  Date has occurred in which event all sums due thereon shall be
immediately due and payable.

         (e) Conversion  Options.  The Company may elect to convert any Bankers'
Acceptance on the last day of the then current  Interest Period relating thereto
to a Base Rate Loan by giving advance notice to the Administrative Agent of such
election.  If no Default shall have occurred and be  continuing,  subject to the
terms of this  Agreement,  the Company may elect to convert all or any part of a
Base  Rate Loan at any time and from time to time to a  Bankers'  Acceptance  by
giving one (1) Business Day's advance notice to the Administrative Agent of such
election;  provided  that any  conversion  of any Base Rate Loan into a Bankers'
Acceptance  shall be in an amount not less than  $1,000,000 in the aggregate for
all Lenders and in whole multiples of $100,000.

         (f) Pro Rata Treatment.  Unless otherwise agreed among the Lenders, all
Loans  shall be made by all  Lenders  pro  rata  relative  to  their  respective
Commitment  Percentage  and the  aggregate  amount of all  Bankers'  Acceptances
issued hereunder shall be issued pro rata by all Lenders relative to


                                        7

<PAGE>



their respective Commitment Percentage,  rounded,  upwards or downwards,  as the
case may be, to the nearest $100,000.

         Section 2.03  Changes of Commitments.

         (a)  Extension  of  Termination  Date.  All of the Lenders and the U.S.
Lenders may extend the  Termination  Date as set forth in Section 2.03(a) of the
U.S. Credit  Agreement,  which section is hereby  incorporated by reference into
this  Agreement  and made a part of this  Agreement to the same extent as if set
forth in full herein,  except that for purposes  hereof,  references  therein to
"Lenders"  and  "Canadian  Lenders"  shall be deemed to be  references  to "U.S.
Lenders" and "Lenders," respectively,  and, as appropriate in the context, other
corresponding changes shall be made, mutatis mutandis.

         (b) Optional  Reduction.  The Company shall have the right to terminate
or to reduce the amount of the Commitments at any time or from time to time upon
not less than one (1) Business  Day's prior notice to the  Administrative  Agent
(which shall promptly notify the Lenders) of each such termination or reduction,
which notice shall specify the effective date thereof and the amount of any such
reduction  (which shall not be less than  $5,000,000,  or any whole  multiple of
$1,000,000 in excess thereof),  and shall be irrevocable and effective only upon
receipt by the Administrative Agent.

         (c)  Reinstatement.  Other than increases pursuant to Section 2.09, the
Commitments once terminated or reduced may not be reinstated.  The amount of the
Available  Canadian  Subcommitment may increase or decrease from time to time in
accordance  with the terms of this  Agreement,  including  but not  limited  to,
Section 2.09.

         Section 2.04  Commitment  Fee and Other Fees.  The Company shall pay to
the Administrative  Agent for the account of the Lenders an aggregate commitment
fee on the daily  average  unused  amount of such  Lender's  Available  Canadian
Subcommitment  for the period  from and  including  the  Effective  Date of this
Agreement to and  including the  Termination  Date, at a rate per annum equal to
the Facility Fee Rate.  The  commitment  fee shall be payable in arrears on each
Quarterly Date and on the Termination Date.

         Section 2.05 Lending Offices.  The Loans made and Bankers'  Acceptances
accepted  and  purchased  by each Lender  shall be made and  maintained  at such
Lender's Applicable Lending Office, which shall be located in Canada.

         Section 2.06 Several Obligations. The failure of any Lender to make any
funds  available in connection with any Borrowing to be funded by such Lender on
the date specified therefor shall not relieve any other Lender of its obligation
to provide such funds on such date, but neither the Administrative Agent nor any
Lender shall be responsible for the failure of any other Lender to provide funds
to be provided by such other Lender.

         Section 2.07  Notes.

         (a) Single  Promissory  Note.  The Loans made by each  Lender  shall be
evidenced by a single  promissory note of the Company in substantially  the form
of Exhibit A hereto,  dated as of the  Effective  Date or such later date upon a
permitted assignment of all or any portion of such Note, payable to the order of
such Lender in a principal  amount equal to the maximum amount of its Commitment
as originally in effect and otherwise duly completed. The date, amount, interest
rate and maturity  date of each Loan made by each Lender,  and all payments made
on account of the principal thereof, shall be recorded by

7
                                        8

<PAGE>



such  Lender on its books  and,  prior to any  transfer  of the Note held by it,
endorsed  by  such  Lender  on  the  schedule  attached  to  such  Note  or  any
continuation thereof.

         (b) No Right to Subdivide. No Lender shall be entitled to have its Note
subdivided,  by  exchange  for  promissory  notes  of  lesser  denominations  or
otherwise,  except  in  connection  with a  permitted  assignment  of all or any
portion  of such  Lender's  Commitment,  Loans  and  Note  pursuant  to  Section
12.03(b).

         Section 2.08  Prepayments.

         (a)  Optional  Prepayments.  The  Company  may prepay any Loans or cash
collateralize  Bankers'  Acceptances  on any  Business  Day upon  notice  to the
Administrative  Agent (which shall  promptly  notify the Lenders),  which notice
shall be given by the  Company  not later than 12:00 noon  Toronto  time on such
Business  Day,  shall specify the amount of the  prepayment  (which shall be not
less than $1,000,000 or the remaining balance of Base Rate Loans outstanding, if
less)  and  shall  be  irrevocable  and  effective  only  upon  receipt  by  the
Administrative  Agent,  provided that  interest on the principal  prepaid on any
Loan,  accrued to the prepayment date, shall be paid on the prepayment date. Any
prepayment  of any Bankers'  Acceptances  shall be subject to the  provisions of
Sections 2.08(d), 2.08(e) and 5.05.

         (b) Mandatory Prepayment Upon Reduction of Commitment. If, after giving
effect to any  termination or reduction of the  Commitments  pursuant to Section
2.03, the sum of the outstanding aggregate principal amount of the Loans and the
Acceptance  Exposure exceeds the aggregate  amount of the Commitments,  then the
Company  shall on the date of such  termination  or reduction  pay or prepay the
amount of such excess amount for  application  first,  towards  reduction of the
outstanding  principal  balance  of the Notes and then,  if  necessary,  by cash
collateralizing  (or  prepaying if acceptable  to the holder  thereof)  Bankers'
Acceptances,  if any,  then  outstanding  subject to the  provisions  of Section
2.08(d). The Company shall on the date of such termination or reduction also pay
any amounts payable pursuant to Section 5.05 in connection therewith.

         (c) No Penalty or Premiums.  Subject to  compensation  requirements  of
Section 5.05 hereof, all prepayments shall be without premium or penalty.

         (d) Pro Rata  Treatment.  Without  duplication  of  Section  5.05,  but
subject to Section 2.08(e),  any prepayment of Bankers'  Acceptances shall be in
an amount  equal to the full face amount of any Bankers'  Acceptance  so prepaid
(less any unearned  Discount Amount and Stamping Fee), and be pro rata among all
Lenders relative to their respective Commitments.

         (e) Bankers'  Acceptances.  A Bankers' Acceptance may only be repaid on
the last day of its Interest  Period unless  consented to by the holder thereof.
In  lieu  of  prepayment  of  a  Bankers'  Acceptance,   the  Company  may  cash
collateralize a Bankers' Acceptance by delivery to the Administrative  Agent for
distribution to each Lender such  discounted  amount in respect of such Bankers'
Acceptance as the Administrative  Agent,  acting reasonably,  advises the Lender
will enable the Lender, based upon the rate of return the Lender will be able to
earn on the  funds so  received,  to pay the full face  amount of such  Bankers'
Acceptance on the last day of such Interest Period.

Bankers'  Acceptances that the Lenders will loan or accept to or for the Company
at any one time  prior to the  Termination  Date.  On the  Effective  Date,  the
Allocated Canadian Borrowing Base shall be U.S. $7,000,000.

         (b) Reallocation. The Company, the Administrative Agent and the Lenders
agree that OEI-  Louisiana  shall have the right to request  that the  Allocated
Canadian  Borrowing  Base be  increased or  decreased,  and the  Allocated  U.S.
Borrowing  Base be  decreased or  increased,  respectively,  in a  corresponding
amount, all as more particularly set forth in Section 2.09(a) of the U.S. Credit
Agreement,  which  provisions  are hereby  incorporated  by reference  into this
Agreement  and made a part of this  Agreement to the same extent as if set forth
in full herein, except that for purposes hereof, references therein to "Lenders"

"Lenders," respectively, and, as appropriate in the context, other corresponding
changes shall be made, mutatis mutandis.

         (c) No Change to Global  Commitment.  The Company,  the  Administrative
Agent and the Lenders agree that  reallocations of the Allocated U. S. Borrowing
Base and Allocated  Canadian Borrowing Base shall not, without the prior written
agreement of all the U.S.  Lenders,  the Lenders and  OEI-Louisiana,  affect the
Global Commitment Percentage.

following provisions shall apply:

         (a) On or before 10:30 a.m.  Toronto time on the  Acceptance  Date, the

Lender as to:

                  (i) the Discount Rate;

                  (ii)  the  face  amount  of  the  Bankers'  Acceptances  to be
         purchased by such Lender on such Acceptance Date;

                  (iii)  the  amount of the  Stamping  Fee  applicable  to those
         Bankers'  Acceptances  to be accepted  and  purchased by such Lender on
         such Acceptance  Date,  such Lender being  authorized by the Company to
         collect the Discount Amount and the Stamping Fee out of the proceeds of
         the  Bankers'  Acceptances  upon the Lender's  acceptance  and purchase
         thereof;

                  (iv) the Available Proceeds by subtracting the Discount Amount
         and the Stamping Fee mentioned in subsection (iii) from the face amount
         mentioned in subsection (ii).

         (b) As provided in Section  2.02(c),  not later than 2:00 p.m.  Toronto
time that same day, each Lender shall make available to the Administrative Agent

<PAGE>



maturity date thereof in accordance with the Company's  notice relating  thereto
and  affixing  their  acceptance  stamps  thereto,  and shall  purchase  same as
provided in Section 2.10.

                  Section  2.12  Payment of Bankers'  Acceptances.  The Bankers'
         Acceptances   shall  be  payable  in  accordance   with  the  following
         provisions:

         (a) If  such  Bankers'  Acceptances  are  held by or  presented  to the
Accepting  Lender or the  Administrative  Agent,  the  Company  shall pay to the
Administrative  Agent for the account of each Lender an amount equal to the face
amount of the Bankers'  Acceptances of such Lender on their respective  maturity
dates.  In the event that any Bankers'  Acceptance  is presented to the Company,
rather than the Accepting Lender thereof, for payment on its respective maturity
date and the Company shall have made payments to the holders  thereof,  then the
Company shall give notice to the  Administrative  Agent to such effect  together
with the original  canceled  Bankers'  Acceptance and the  Administrative  Agent
shall promptly notify the Lenders.

         (b) In the event the Company fails to notify the  Administrative  Agent
in  writing,  not later  than  12:00  Noon,  one (1)  Business  Day prior to any
maturity date of a Bankers' Acceptance, that the Company intends to pay with its
own funds the amount of the Bankers'  Acceptances due on such maturity date, the
Company  shall be deemed,  for all  purposes,  to have given the  Administrative
Agent notice to convert the amount of such Bankers' Acceptances into a Base Rate
Loan and the provisions of Section 2.02(f) shall apply, except save that:

                  (i) such maturity date shall be considered to be the borrowing
         date of such Base Rate Loan;

                  (ii) the  proceeds of such Base Rate Loan shall be used to pay
         the amount of the Bankers' Acceptance due on such maturity date; and

                  (iii) on such maturity  date,  each Lender,  instead of making
         its funds available to the Administrative  Agent to fund such Base Rate
         Loan,  shall  first  directly  apply its pro rata share of such Loan in
         payment of its pro rata share in the amount of its Bankers' Acceptances
         due on such date.

                 Article III: Payments of Principal and Interest

         Section  3.01  Repayment  of  Loans.   The  Company  will  pay  on  the

         Section 3.02  Interest.

         (a) The Company will pay to the Administrative Agent for the account of
each Lender  interest on the unpaid  principal  amount of each Loan made by such

date such Loan shall be paid in full,  at the Base Rate (as in effect  from time
to time) plus the Applicable Margin for such Loan, but in no event to exceed the
Highest Lawful Rate.

         (b) Accrued  interest on each Loan shall be payable  quarterly  on each
Quarterly  Date,  except that interest  payable after  maturity shall be payable
from time to time on demand.

         (c) Promptly after the  determination of any interest rate provided for
herein or any change therein,  the Administrative Agent shall notify the Lenders
to which such interest is payable and the Company.

          ARTICLE IV: PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

         Section 4.01 Payments.  Except to the extent otherwise provided herein,
all payments of principal,  interest and other amounts to be made by the Company

Dollars, in immediately  available funds, to the Administrative Agent at transit
#09591,  account number  219-2474-4  maintained by the  Administrative  Agent at
Royal Bank of Canada,  Correspondent Banking Division, Toronto Canada, not later
than 12:00 noon Toronto Time on the date on which such payments shall become due
(each  such  payment  made after such time on such due date to be deemed to have
been made on the next  succeeding  Business Day). The Company shall,  subject to
Section  4.02,  at the time of making each payment  under this  Agreement or any
Note or  Bankers'  Acceptance,  specify to the  Administrative  Agent the Loans,
Bankers'  Acceptances or other amounts payable by the Company hereunder to which
such payment is to be applied (and in the event that it fails to so specify, and
such day is not a  Quarterly  Date or other  day on which a  payment  of  either
interest  or  principal  is due,  then such  payments  shall be  applied  in the
following  order:  first, to interest  accrued on Loans,  second,  any excess to
reduce the aggregate  principal amount then outstanding on the Loans and, third,
any  excess to  Bankers'  Acceptances;  provided,  however,  that if an Event of
Default has occurred and is continuing,  the Administrative Agent may distribute
such  payment to the  Lenders in such manner as it or the  Required  Lenders may
determine to be appropriate,  subject to Section 4.02). Each payment received by
the Administrative Agent under this Agreement or any Note or Bankers' Acceptance
for  the  account  of a  Lender  shall  be paid  promptly  to  such  Lender,  in
immediately  available  funds, for account of such Lender's  Applicable  Lending
Office for the Loan or Bankers'  Acceptances in respect of which such payment is
made. If the due date of any payment  under this  Agreement or any Loan Document
would  otherwise  fall on a day which is not a  Business  Day such date shall be
extended to the next  succeeding  Business Day and interest shall be payable for
any amount so extended for the period of such extension.

         Section 4.02 Pro Rata Treatment.  Except to the extent agreed among the
Lenders or otherwise  provided herein: (a) each Borrowing from the Lenders under
Section 2.01 shall be made from the Lenders,  each payment of commitment  fee or
other fees under Section 2.04 shall be made for account of the Lenders, and each
termination  or reduction of the amount of the  Commitments  under  Section 2.03
shall be applied to the Commitments of the Lenders,  pro rata according to their
respective Commitment  Percentages,  (b) each payment of Bankers' Acceptances or
principal  of Loans by the Company  shall be made for account of the Lenders pro
rata in accordance with the aggregate  unpaid principal amount of Loans and face
amount of Bankers'  Acceptances  held or purchased by the Lenders,  and (c) each
payment of  interest  on Loans by the  Company  shall be made for account of the
Lenders pro rata in  accordance  with the amounts of interest due and payable on
such Loans to the respective Lenders.

         Section 4.03 Computations. Interest on Loans and fees shall be computed
on the basis of a year of 365 or 366 days,  as the case may be, and actual  days
elapsed  (including  the first day but excluding the last day)  occurring in the

days. Any rates of interest not expressed in this Credit  Agreement on the basis
of a 365 day or 366 day year are the  equivalent,  expressed on a calendar  year
basis, of the same rate of interest  multiplied by a fraction,  the numerator of
which is the  actual  number  of days in the  applicable  calendar  year and the
denominator  of which is the number of days on which interest is expressed to be
based.

         Section 4.04 Non-receipt of Funds by the Administrative  Agent.  Unless
the  Administrative  Agent  shall have been  notified by a Lender or the Company
prior  to  the  date  on  which  a  payment  is  scheduled  to be  made  to  the
Administrative Agent of (in the case of a Lender) the proceeds of a Borrowing to
be made  by it  hereunder  or (in the  case of the  Company)  a  payment  to the
Administrative  Agent for account of one or more of the Lenders  hereunder (such
payment  being  herein  called a  "Required  Payment"),  which  notice  shall be
effective upon receipt,  that it does not intend to make the Required Payment to
the Administrative  Agent, the Administrative 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(s)
on such date and,  if such Lender or the Company (as the case may be) has not in
fact made the Required Payment to the Administrative  Agent, the recipient(s) of
such payment shall, on demand,  repay to the Administrative  Agent the amount so
made available  together with interest thereon in respect of each day during the
period  commencing  on the  date  such  amount  was  so  made  available  by the
Administrative  Agent  until the date the  Administrative  Agent  recovers  such
amount at a rate per annum equal to the Base Rate for such day,  but in no event
to exceed the Highest Lawful Rate.

         Section 4.05  Sharing of Payments, Etc.

         (a) The Company agrees that, in addition to (and without limitation of)
any right of set-off, bankers' lien or counterclaim a Lender may otherwise have,
each  Lender  shall be  entitled  (after  consultation  with the  Administrative
Agent),  at its option,  during the existence of an Event of Default,  to offset
balances held by it for account of the Company at any of its offices, in Dollars
or in any other  currency,  against any  principal of or interest on any of such
Lender's  Loans or Bankers'  Acceptances,  or any other  amount  payable to such
Lender hereunder which is not paid when due (regardless of whether such balances
are then due to the Company),  in which case such Lender shall  promptly  notify
the Company and the  Administrative  Agent thereof,  provided that such Lender's
failure to give such notice shall not affect the validity thereof.

         (b) If any Lender shall obtain  payment of any principal of or interest
on any Loan or  reimbursement  on any Bankers'  Acceptance made available to the
Company  under this  Agreement  through  the  exercise  of any right of set-off,
banker's lien or counterclaim or similar right or otherwise, and, as a result of
such  payment,  such  Lender  shall have  received a greater  percentage  of the
principal  or interest or  reimbursement  obligation  then due  hereunder by the
Company to such Lender than the percentage  received by any other Lenders,  such
Lender shall promptly purchase from such other Lenders participations in (or, if
and to the extent  specified by such Lender,  direct  interests in) the Loans or
Bankers'  Acceptances made by such other Lenders (or in interest due thereon, as
the case may be), and make such other  adjustments from time to time as shall be
equitable,  to the end that all the  Lenders  shall  share the  benefit  of such
excess  payment  (net of any  expenses  which may be  incurred by such Lender in
obtaining or preserving  such excess  payment) pro rata in  accordance  with the
aggregate  unpaid  principal  and  interest  on  the  Loans  and   reimbursement
obligations on the Bankers' Acceptances held or accepted by each of the Lenders.
To such end, all the Lenders shall make appropriate adjustments among themselves
(by the resale of participations sold or otherwise) if such payment is rescinded
or must otherwise be restored.  The Company agrees that any Lender so purchasing
a participation (or

                                       13

<PAGE>



direct interest) in the Loans or Bankers'  Acceptances made by other Lenders (or
in interest due thereon, as the case may be) may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender were a direct holder of Loans or acceptor of Bankers'
Acceptances,  as the case may be, in the amount of such  participation.  Nothing
contained  herein  shall  require any Lender to exercise any such right or shall
affect  the  right of any  Lender  to  exercise,  and  retain  the  benefits  of
exercising,  any such right with respect to any other indebtedness or obligation
of the Company. If under any applicable bankruptcy,  insolvency or other similar
law,  any  Lender  receives  a secured  claim in lieu of a set-off to which this
Section 4.05 applies, such Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner  consistent  with the rights
of the Lenders  entitled  under this  Section  4.05 to share the benefits of any
recovery on such secured claim.

                   ARTICLE V: YIELD PROTECTION AND ILLEGALITY

         Section 5.01  Additional Costs.

         (a)  Regulatory  Change.  The Company shall pay directly to each Lender
from time to time such  amounts as such Lender may  determine to be necessary to
compensate it for any increased  costs  incurred by the Lender which such Lender
determines are  attributable  to its making or maintaining any Loans or Bankers'
Acceptances  or its  obligation  to  make  any  Loans  or  Bankers'  Acceptances
hereunder, or any reduction in any amount receivable by such Lender hereunder in
respect of any of such Loans or Bankers'  Acceptances  (such  increases in costs
and reductions in amounts  receivable being herein called  "Additional  Costs"),
resulting from any Regulatory Change which: (i) changes the basis of taxation of
any amounts  payable to such Lender  under this  Agreement  in respect of any of
such Loans or Bankers' Acceptances (other than franchise taxes, taxes on capital
and/or gross  receipts or taxes imposed on the overall net income of such Lender
or of  its  Applicable  Lending  Office  for  any  of  such  Loans  or  Bankers'
Acceptances by the jurisdiction in which such Lender has its principal office or
such Applicable Lending Office ("Excluded Taxes"));  or (ii) imposes or modifies
any  reserve,  special  deposit,  minimum  capital,  capital  ratio  or  similar
requirements  relating to any  extensions  of credit or other  assets of, or any
deposits with or other  liabilities  of, such Lender,  or any Commitment of such
Lender;  or (iii) imposes any other  condition  affecting  this Agreement or its
Loans  or  Bankers'  Acceptances  (or  any  of  such  extensions  of  credit  or
liabilities) or Commitment. If any Lender requests compensation from the Company
under this Section 5.01,  the Company may, by notice to such Lender (with a copy
to the  Administrative  Agent),  suspend the  obligation  of such Lender to make
additional Loans or accept and purchase additional  Bankers'  Acceptances of the
type with respect to which such  compensation  is requested until the Regulatory
Change  giving  rise to such  request  ceases to be in effect (in which case the
provisions of Section 5.04 shall be applicable).

         (b) Capital  Adequacy.  Without  limiting  the effect of the  foregoing
provisions of this Section 5.01 (but without duplication), the Company shall pay
directly to each Lender from time to time on request such amounts as such Lender
may determine to be necessary to  compensate  such Lender for any costs which it
determines are attributable to the maintenance by such Lender (or any Applicable
Lending  Office),  pursuant  to any  law or  regulation  or any  interpretation,
directive  or request  (whether  or not having the force of law) of any court or
governmental or monetary  authority  following any Regulatory Change, of capital
in respect of its Commitment,  such compensation to include, without limitation,
an amount  equal to any  reduction  of the rate of return on assets or equity of
such Lender (or any Applicable  Lending Office) to a level below that which such
Lender (or any Applicable  Lending Office) could have achieved but for such law,
regulation, interpretation, directive or request.

<PAGE>



         Section  5.02  Illegality.  If the  introduction  of or any  change in,
applicable  law,  regulation,   treaty  or  official  directive,  or  regulatory
requirement or the interpretation or application  thereof by any court or by any
governmental  authority  charged  with  the  administration  thereof,  makes  it
unlawful,  or  prohibited  for any  Lender  (in its  sole  opinion)  to  accept,
purchase, trade or hold Bankers' Acceptances, such Lender may, by written notice
to the Administrative  Agent, which notice shall be promptly communicated by the
Administrative  Agent to the  Company,  terminate  its  obligations  to  accept,
purchase, trade or hold Bankers' Acceptances and the Company shall repay or cash
collateralize,  as the case may be, such Bankers'  Acceptances  then outstanding
forthwith  together with any payments required under Section 5.05, or at the end
of such period as such Lender in its discretion agrees, (it being understood and
agreed that the Lender shall use its best efforts to permit such  prepayment  to
occur  on the  maturity  date  of  Bankers'  Acceptances,  if  this  is  legally
permissible)  together with all  additional  amounts as may be applicable to the
date of payment and may reborrow,  subject to the terms hereof, any amount which
has been prepaid  pursuant to this Section  5.02, by way of one of the remaining
legal basis of Borrowings available under this Agreement, as provided in Section
5.04.

         Section 5.03  Additional Cost in Respect of Tax.

         (a)  Payments  Free and Clear.  Each  payment to be made by the Company
hereunder or in  connection  herewith to any Lender or any other Person shall be
made free and clear of and without deduction for or on account of any Tax unless
the  Company  is  required  to make such  payment  subject to the  deduction  or
withholding of Tax, in which case (except for Excluded Taxes) the sum payable by
the Company in respect of which such  deduction or withholding is required to be
made shall be increased to the extent necessary to ensure that, after the making
of such deduction or  withholding,  such other Person receives and retains (free
from any liability in respect of any such  deduction or  withholding)  a net sum
equal to the sum  which it would  have  received  and so  retained  had not such
deduction or withholding been made or required to be made.

         (b)  Obligation to Indemnify.  If (i) any Lender or the  Administrative
Agent, on behalf of such Lender or on its own behalf, is required by law to make
any payment on account of any Tax (except for Excluded  Taxes) on or in relation
to any sum received or receivable hereunder by such Lender or the Administrative
Agent,  or (ii) any  liability  in  respect  of any such  payment  is  asserted,
imposed,  levied or assessed against such Lender or the Administrative Agent (as
the case may be) against such payment or liability,  the Company shall  promptly
pay to the  Administrative  Agent  or such  Lender,  as the  case  may  be,  any
additional  amounts  necessary to compensate  the  Administrative  Agent or such
Lender for such  payment  together  with any  interest,  penalties  and expenses
payable or incurred in connection  therewith.  If the Administrative  Agent or a
Lender has paid over on account of Tax  (other  than  Excluded  Taxes) an amount
paid to the  Administrative  Agent or such Lender by the Company pursuant to the
foregoing  indemnification and the amount so paid over is subsequently  refunded
to  the  Administrative  Agent  or  such  Lender,  in  whole  or  in  part,  the
Administrative  Agent or such Lender, as appropriate,  shall promptly remit such
amount refunded to the Company.

         (c) Notice of Changes;  Proof of Payment. If at any time the Company is
required by law to make any deduction or withholding  from any sum payable by it
hereunder or in connection herewith (or if thereafter there is any change in the
rates at which or the  manner  in which  such  deductions  or  withholdings  are
calculated) the Company shall promptly notify the Administrative  Agent thereof.
If the Company makes any payment hereunder or in connection  herewith in respect
of which it is required by law to make any deduction or withholding it shall pay
the full amount to be deducted  or  withheld to the  relevant  taxation or other
authority within the time allowed for such payment under applicable law

                                        5

<PAGE>



and shall deliver to the  Administrative  Agent within thirty (30) days after it
has made such payment to the  applicable  authority (i) a receipt issued by such
authority or (ii) other evidence  reasonably  satisfactory to the Administrative
Agent  evidencing the payment to such authority of all amounts so required to be
deducted or withheld from such payment.

         Section 5.04 Base Rate Loans pursuant to Sections 5.01 and 5.02. If the
obligation of any Lender to accept and purchase  Bankers'  Acceptances  shall be
suspended  pursuant to Section  5.01 or 5.02  ("Affected  Loans"),  all Affected
Loans which  would  otherwise  be made  available  by such Lender  shall be made
instead as Base Rate Loans (and, if an event  referred to in Section  5.01(a) or
Section  5.02 has  occurred and such Lender so requests by notice to the Company
with a copy to the Administrative  Agent, all Affected Loans of such Lender then
outstanding  shall be automatically  converted into Base Rate Loans,  subject to
Section 5.05,  on the date  specified by such Lender in such notice) and, to the
extent that Affected  Loans are so made as (or converted  into) Base Rate Loans,
all payments  which would  otherwise be applied to such Lender's  Affected Loans
shall be applied instead to its Base Rate Loans.

         Section 5.05 Compensation.  The Company shall pay to the Administrative
Agent for account of each  Lender,  upon the request of such Lender  through the
Administrative  Agent,  such  amount or amounts as shall be  sufficient  (in the
reasonable  opinion  of such  Lender)  to  compensate  it for any loss,  cost or
expense which such Lender determines are attributable to:

         (a) any payment or conversion of a Bankers'  Acceptance  for any reason
(including,  without  limitation,  the  acceleration  of the Loans  pursuant  to
Section 10.01) on a date other than the last day of the Interest Period for such
Bankers' Acceptance; or

         (b) any  failure  by the  Company  for any  reason  (including  but not
limited to, the failure of any of the conditions  precedent specified in Article
VI to be satisfied, but excluding failures arising out of the negligence,  gross
negligence  or wilful  misconduct  of a Lender or the  Administrative  Agent) to
issue a  Bankers'  Acceptance  to such  Lender  on the date  for  such  issuance
specified in the relevant notice of Borrowing given pursuant to Section 2.02.

         Section 5.06  Avoidance of Taxes and Additional Costs.

         (a) Change Applicable Funding Office. If a Lender makes any claim under
Section  5.01 or  Section  5.03 in respect of  Additional  Costs or Taxes,  such
Lender  shall be obligated  to use  reasonable  efforts to designate a different
Applicable  Lending  Office  for the  Commitment  or the  Loans  or the  Bankers
Acceptances of such Lender affected by such event if such designation will avoid
the need for, or reduce the amount of, such  compensation  or the  imposition of
any Taxes and will not, in the sole opinion of such Lender,  be  disadvantageous
to such  Lender;  provided  that such  Lender  shall  have no  obligation  to so
designate an Applicable Lending Office located in Canada.

         (b) Replacement.  If any Lender claims (i) payment of Additional Costs,
(ii) the  inability  to make or  maintain  the Bankers  Acceptances  pursuant to
Section  5.01  or 5.02  (when  such  inability  is not  then  being  claimed  by
substantially  all of the  Lenders)  or (iii)  payment of any Taxes  pursuant to
Section  5.03,  then the  Company  shall  have the right,  upon  payment of such
requested Additional Costs or Taxes to (i) prepay the Loans made by such Lender,
cash  collateralize  the Bankers  Acceptances then  outstanding  which have been
discounted by such Lender,  and terminate the Commitment of such Lender on a non
pro rata basis or (ii) subject to the approval of the Administrative Agent (such
approval not to be unreasonably  withheld or delayed),  find one or more Persons
willing to assume the Loans, Commitment


                                       16

<PAGE>



and other  obligations  of such  Lender and replace  such Lender  pursuant to an
Assignment and  Acceptance.  Any such assumption  shall be effected  pursuant to
Section  12.03(b).  The Company shall not,  however,  be entitled to replace any
Lender if an event which with notice or lapse of time, or both, would constitute
a Default or an Event of Default exists at the time.

         Section  5.07  Limitation  on Right to  Compensation.  Any  demand  for
compensation  pursuant to Article V (other than Section 5.03) must be made on or
before six (6) months after the Lender incurs the expense, cost or economic loss
referred  to or such  Lender  shall be deemed to have  waived  the right to such
compensation.  Any demand for compensation pursuant to Section 5.03 must be made
on or before  twelve (12) months after the Lender  incurs the  expense,  cost or
economic  loss  referred  to or such  Lender  shall be deemed to have waived the
right to such compensation.

         Section  5.08  Compensation  Procedure.  Each  Lender  will  notify the
Company  of any event  occurring  after the date of this  Agreement  which  will
entitle  such Lender to  compensation  pursuant to this Article V as promptly as
practicable  after it obtains  knowledge  thereof and determines to request such
compensation,  and will furnish the Company with a certificate setting forth the
basis and amount of each  request by such  Lender  for  compensation  under this
Article V. Such  certificate  shall also include (i)  calculations in reasonable
detail  computing  such claim,  and (ii) a statement from such Lender that it is
asserting its right for indemnity or compensation not solely with respect to the
Indebtedness  outstanding  under this  Agreement,  but is generally  making such
claims with respect to similar borrowers in connection with transactions similar
to the one contemplated in this Agreement. Determinations and allocations by any
Lender for  purposes of this  Article V of the effect of any  Regulatory  Change
pursuant to Section 5.01(a),  or of the effect of capital maintained pursuant to
Section  5.01(b),  on its costs or rate of return of  accepting  and  purchasing
Bankers'  Acceptances  or  maintaining  Loans or its obligation to make Loans or
accept and purchase  Bankers'  Acceptances,  or on amounts  receivable  by it in
respect of Loans or Bankers' Acceptances, and of the additional amounts required
to compensate  such Lender under this Article V, shall be  conclusive,  provided
that such determinations and allocations are made on a reasonable basis.

                        ARTICLE VI: CONDITIONS PRECEDENT

         Section 6.01 Initial Loan or Bankers' Acceptance. The obligation of the

                       ARTICLE VIII: AFFIRMATIVE COVENANTS

         The  Company  agrees  that,  so long as any of the  Commitments  are in
effect  and  until  payment  in  full  of all  Loans  and  Bankers'  Acceptances
hereunder,  all interest  thereon and all other  amounts  payable by the Company
hereunder:

         Section 8.01 Incorporation By Reference. The Company will not, and will
not permit any of its  Subsidiaries  to, enter into, make, take, cause or suffer
to exist any transaction,  action,  omission or condition,  if such transaction,
action,  omission or condition constitutes a breach of any covenant set forth in
Sections 8.01,  8.02,  8.03,  8.04, 8.07 and 8.08 of the U.S. Credit  Agreement,
which Sections  (together  with the relevant  provisions of any other Section or
Sections  of  the  U.S.  Credit   Agreement  to  which  they  refer,   including
definitions) are hereby incorporated by reference into this Agreement and made a
part of this Agreement to the same extent as if those  provisions were set forth

Intercreditor  Agreement,  any  provision  of this  Agreement  or any other Loan
Document  may be  amended,  modified  or waived as  provided in the U. S. Credit

Canadian Subcommitment,  or reduces the interest rate applicable to the Loans or

         Section 12.03  Assignments and Participations.

         (a) The  Company  may not assign its  rights or  obligations  hereunder
without the prior consent of all of the Lenders and the Administrative Agent.

         (b) Each  Lender may,  upon the written  consent of the Company and the
Administrative  Agent,  which  consent  shall not be  unreasonably  withheld  or
delayed,  assign to one or more  assignees  all or a portion  of its  rights and
obligations  under this  Agreement  pursuant  to an  Assignment  and  Acceptance
Agreement   substantially   in  the  form  of  Exhibit  C  (an  "Assignment  and
Acceptance")  provided,  however,  that (i) any such assignment  shall be in the
aggregate  amount of at least  $5,000,000,  the  entire  amount of the  Lender's
Commitment,  if less, or such lesser amount to which the Company has  consented,
(ii)  the  assignee  shall  pay to the  Administrative  Agent a  processing  and
recordation  fee of  $3,500;  provided  that such fee shall  not be  payable  in
conjunction with any assignments occurring within 30 days of the Effective Date,
and (iii) the  assignee is a resident  of Canada for  purposes of the Income Tax
Act (Canada). Any such assignment will become effective upon the issuance by the
Administrative  Agent of a letter of  acknowledgment  reflecting such assignment
and the  resultant  effects  thereof  on the  Commitments  of the  assignor  and
assignee, and the principal amount outstanding of the Loans owed to the assignor
and assignee,  the Administrative  Agent hereby agreeing to effect such issuance
no later than five (5)  Business  Days after its  receipt of an  Assignment  and
Acceptance  executed  by all  parties  thereto.  Promptly  after  receipt  of an
Assignment and Acceptance  executed by all parties thereto,  the  Administrative
Agent shall send to the Company a copy of such executed Assignment and


                                       21

<PAGE>



Acceptance.  Upon  receipt  of such  executed  Assignment  and  Acceptance,  the
Company, will, at its own expense, execute and deliver new Notes to the assignor
and/or assignee,  as appropriate,  in accordance with their respective interests
as they appear on the Administrative Agent's letter of acknowledgment.  Upon the
effectiveness  of any  assignment  pursuant to this  Section,  the assignee will
become a "Lender," if not already a "Lender," for all purposes of this Agreement
and the other Loan Documents.  The assignor shall be relieved of its obligations
hereunder  to the  extent of such  assignment  (and if the  assigning  Lender no
longer holds any rights or  obligations  under this  Agreement,  such  assigning
Lender shall cease to be a "Lender" hereunder except for the purposes of Section
12.04 hereof and the Sections  referred to therein).  The  Administrative  Agent
will prepare on the last  Business Day of each month during which an  assignment
has become  effective  pursuant to this  Section a revised  Annex I to the U. S.
Credit  Agreement  giving effect to all such  assignments  effected  during such
month,  and  will  promptly  provide  the  same to the  Company  and each of the
Lenders.

         (c) Each Lender may transfer,  grant or assign participations in all or
any part of such Lender's interests hereunder pursuant to this subsection to any
Person,  provided that: (i) such Lender shall remain a "Lender" for all purposes
of this Agreement and the transferee of such participation  shall not constitute
a "Lender" hereunder; and (ii) no participant under any such participation shall
have rights to approve any amendment to or waiver of this  Agreement,  the Notes
or any Loan  Document  except to the extent such  amendment  or waiver would (x)
extend the  Termination  Date,  (y) reduce the  interest  rate  (other than as a
result of waiving the  applicability of any  post-default  increases in interest
rates)  or fees  applicable  to any of the  Commitments  or Loans in which  such
participant  is  participating,  or postpone the payment of any thereof,  or (z)
release all or substantially all of the collateral (except as expressly provided
in the Loan Documents)  supporting any of the Commitments or Loans in which such
participant  is  participating.  In the  case  of any  such  participation,  the
participant  shall not have any rights  under this  Agreement or any of the Loan
Documents (the  participant's  rights against the granting  Lender in respect of
such  participation  to be those set  forth in the  agreement  with such  Lender
creating such  participation),  and all amounts payable by the Company hereunder
shall be determined as if such Lender had not sold such participation,  provided
that if the  participant  is a resident of Canada for purposes of the Income Tax
Act (Canada) and has its principal office in Canada,  such participant  shall be
entitled to receive  additional  amounts under Article V on the same basis as if
it were a Lender. In addition,  each agreement  creating any participation  must
include  agreements by the  participant to be bound by the provisions of Section
12.14 of the U.S.  Credit  Agreement as  incorporated  herein and forbidding the
transfer, assignment or sub-participation of such participation.

         (d) The Lenders may furnish any  information  concerning the Company in
the  possession of the Lenders from time to time to assignees  and  participants
(including prospective assignees and participants);  provided that, such Persons
agree in writing  to be bound by the  provisions  of  Section  12.14 of the U.S.
Credit Agreement as incorporated herein by Section 12.01.

         Section 12.04 Survival.  The obligations of the Company,  the Agent and
the Lenders under  Sections 5.01,  5.03 and 5.05 hereof,  and Sections 12.03 and
12.14 of the U.S. Credit Agreement as incorporated herein by Section 12.01 shall
survive the repayment of the Loans and the termination of the Commitments.

connection  therewith,  or the execution,  legality,  validity,  enforceability,
genuineness,  sufficiency  or  value  of the  Credit  Agreement,  or  any  other
instrument or document  furnished  pursuant  thereto,  other than that it is the
legal and  beneficial  owner of the interest  being assigned by it hereunder and
that  such  interest  is free and clear of any  adverse  claim;  (iii)  makes no

instrument or document furnished  pursuant thereto;  and (iv) attaches the Notes
held by it  evidencing  the  Assigned  Interest  and  requests  that the Company
exchange  such Notes for new Notes  payable to the Assignor (if the Assignor has
retained  any interest in the Assigned  Interest)  and new Notes  payable to the
Assignee in the  respective  amounts  which  reflect the  assignment  being made
hereby  (and after  giving  effect to any other  assignments  which have  become
effective on the Effective Date).

         3.  The  Assignee  (i)  represents  and  warrants  that  it is  legally
authorized to enter into this Assignment and  Acceptance;  (ii) confirms that it
has  received  a copy of the  Credit  Agreement,  together  with  copies  of the

8.01  thereof,  and  such  other  documents  and  information  as it has  deemed
appropriate  to  make  its own  credit  analysis;  (iii)  agrees  that it  will,
independently  and without  reliance upon either the  Administrative  Agent, any
other Lender or the Assignor and based on such  documents and  information as it
shall deem appropriate at the time, continue

Agreement in respect of the Assigned Interest (including without limitation, all
payments of principal, interest and fees with respect thereto) for the period up
to, but not including,  the Effective Date,  shall be made to the Assignor,  and
for the period from and after the Effective  Date shall be made to the Assignee.

Acceptance  and  Section  12.03 of the  Credit  Agreement,  have the  rights and
obligations  thereunder,  and (ii) the Assignor shall, to the extent provided in

         Section 2.01 Obligations  Guaranteed.  The Guarantor hereby irrevocably
and   unconditionally   guarantees   the  prompt  payment  at  maturity  of  the
Obligations.

         Section  2.02  Nature  of  Guaranty.  This  guaranty  is  an  absolute,
irrevocable,  completed and continuing guaranty of payment and not a guaranty of
collection,  and no notice of the Obligations or any extension of credit already
or  hereafter  contracted  by or extended  to the  Company  need be given to the
Guarantor.  The  guaranty  evidenced  hereby is joint and several with all other
guarantees of the Obligations. This guaranty may not be revoked by the Guarantor
and shall  continue to be effective  with respect to debt under the  Obligations
arising or created  after any  attempted  revocation  by the Guarantor and shall
remain in full force and effect until the  Obligations  are paid in full and the
Aggregate  Commit ments are terminated,  notwithstanding  that from time to time
prior thereto no Obligations may be outstanding. The Company, the Administrative
Agent and the Lenders may modify, alter, rearrange, extend for any period and/or
renew from time to time, the  Obligations and the  Administrative  Agent and the
Lenders  may waive any  Defaults  or Events  of  Default  without  notice to the
Guarantor and in such event the Guarantor  will remain fully bound  hereunder on
the  Obligations.  Subject to the terms of the Credit  Agreement,  this Guaranty
Agreement may be enforced by the Administrative Agent and/or the Lenders and any
subsequent  holder  of  the  Obligations  and  shall  not be  discharged  by the
assignment  or  negotiation  of all or part of the  Obligations.  The  Guarantor
hereby expressly waives presentment,  demand, notice of non-payment, protest and
notice of protest and dishonor,  notice of Event of Default, notice of intent to
accelerate the maturity and notice of acceleration of the maturity and any other
notice in connection with the Obligations, and also notice of acceptance of this
Guaranty Agreement,  acceptance on the part of the Administrative  Agent and the
Lenders being conclusively presumed by their request for this Guaranty Agreement
and delivery of the same to the Administrative Agent.

         Section  2.03  Lenders'  Rights.  Subject  to the  terms of the  Credit
Agreement,  the Guarantor authorizes the Lenders (or the Administrative Agent on
behalf of the  Lenders),  without  notice or demand and  without  affecting  the
Guarantor's obligation hereunder,  to take and hold agreed-upon security for the
payment of the Obligations,  and exchange,  enforce,  waive and release any such
security;  and to apply  such  security  and  direct the order or manner of sale
thereof as the Administrative Agent and the Lenders



                                       -2-

in their  discretion may determine;  and to obtain a guaranty of the Obligations
from  any one or more  Persons  and at any  time or  times  to  enforce,  waive,
rearrange,  modify,  limit or  release  any of such  other  Persons  from  their
obligations under such guaranties.

         Section 2.04  Guarantor's  Waivers.  The Guarantor  waives any right to
require the  Administrative  Agent and the  Lenders to (a)  proceed  against the
Company or any other Person liable on the Obligations,  (b) enforce their rights
against any other  guarantor of the  Obligations,  (c) proceed or enforce  their
rights against or exhaust any security given to secure the Obligations, (d) have
the Company  joined with the  Guarantor in any suit arising out of this Guaranty
Agreement  and/or the  Obligations,  or (e) pursue any other remedy  whatsoever.
Neither the  Administrative  Agent nor the Lenders shall be required to mitigate
damages or take any action to reduce,  collect or enforce the  Obligations.  The
Guarantor  waives  any  defense  arising  by reason of any  disability,  lack of
corporate  authority  or power,  or other  defense  of the  Company or any other
guarantor of the  Obligations,  and shall remain  liable  hereon  regardless  of
whether the Company or any other  guarantor be found not liable  thereon for any
reason.

         Section 2.05 Maturity of  Obligations;  Payment.  The Guarantor  agrees
that  if the  maturity  of the  Obligations  is  accelerated  by  bankruptcy  or
otherwise,  such maturity  shall also be deemed  accelerated  for the purpose of
this Guaranty Agreement without demand or notice to the Guarantor. The Guarantor
will,  forthwith  upon notice  from the  Administrative  Agent of the  Company's
failure to pay the Obligations at maturity,  pay to the Administrative Agent for
the benefit of the  Administrative  Agent and the Lenders at the  Administrative
Agent's  Principal  Office,  the  amount  due  and  unpaid  by the  Company  and
guaranteed hereby.  The failure of the Administrative  Agent to give this notice
shall not in any way release the Guarantor hereunder.

         Section  2.06  Lenders'  Expenses.  If the  Guarantor  fails to pay the
Obligations after notice from the Administrative  Agent of the Company's failure
to pay any Obligations at maturity  (whether by acceleration or otherwise),  and
if the  Administrative  Agent or the Lenders  obtain the services of an attorney
for collection of amounts owing by the Guarantor hereunder,  or obtain advice of
counsel in respect of any of their rights under this Guaranty  Agreement,  or if
suit is filed to enforce this Guaranty  Agreement,  or if proceedings are had in
any bankruptcy, receivership or other judicial proceedings for the establishment
or collection of any amount owing by the Guarantor  hereunder,  or if any amount
owing by the  Guarantor  hereunder is collected  through such  proceedings,  the
Guarantor agrees to pay to the Administrative  Agent at its Principal Office the
reasonable attorneys' fees of the Administrative Agent and the Lenders.

         Section 2.07 Obligation.  It is expressly agreed that the obligation of
the  Guarantor  for the payment of the  Obligations  guaranteed  hereby shall be
primary and not secondary.

         Section 2.08 Events and  Circumstances  Not Reducing or Discharging the
Guarantor's Obligations. The Guarantor hereby consents and agrees to each of the
following to the fullest extent  permitted by law,  agrees that its  obligations
under this  Guaranty  Agreement  shall not be  released,  diminished,  impaired,
reduced or  adversely  affected by any of the  following,  and waives any rights
(including without limitation rights to notice) which it might otherwise have as
a result of or in connection with any of the following:

         (j)  Payments  Rescinded.  Any  payment by the  Company to any Agent or

to be taken with respect to the Credit  Agreement  or the other Loan  Documents,

it being the  unambiguous  and  unequivocal  intention of the Guarantor that the
Guarantor  shall be obligated to pay the Obligations  when due,  notwithstanding
any occurrence,  circumstance,  event, action, or omission  whatsoever,  whether
contemplated  or  uncontemplated,  and whether or not otherwise or  particularly
described herein,  except for the full and final payment and satisfaction of the
Obligations.

by the Guarantor hereunder,  including without limitation,  any claim, remedy or
right  of   subrogation,   reimbursement,   exoneration,   indemnification,   or

Agent  and  the  Lenders  to  accept  this  Guaranty  Agreement,  the  Guarantor

warranties  will survive the creation of the  Obligations  and any  extension of
credit thereunder) that:

         (a) Benefit to the Guarantor.  The Company is a wholly-owned Subsidiary
of the  Guarantor;  and the  Guarantor's  guaranty  pursuant  to  this  Guaranty
Agreement  reasonably may be expected to benefit,  directly or  indirectly,  the
Guarantor;  and the Guarantor  has  determined  that this Guaranty  Agreement is
necessary  and  convenient  to the  conduct,  promotion  and  attainment  of the
business of the Guarantor and the Company.

<PAGE>



         (b)  Solvency.  It (i) is not  insolvent as of the date hereof and will
not be  rendered  insolvent  as a  result  of  this  Guaranty  Agreement  or the
transactions  contemplated by the Credit Agreement or the making of the Loans or
issuance of Bankers Acceptances thereunder, (ii) is not engaged in a business or
a transaction, or about to engage in a business or a transaction,  for which any
Property or assets remaining with the Guarantor  constitute  unreasonably  small
capital,  and (iii) does not intend to incur,  or believe it will  incur,  debts
that will be beyond its ability to pay as such debts mature.

         (c) No Representation by Administrative  Agent or Lenders.  Neither any
Agent,  Lender nor any other  Person has made any  representation,  warranty  or
statement  to the  Guarantor  in order to induce the  Guarantor  to execute this
Guaranty Agreement.

                                   ARTICLE IV
                          SUBORDINATION OF INDEBTEDNESS

         Section 4.01 Subordination of All Guarantor Claims. As used herein, the
term  "Guarantor  Claims" shall mean all debts and obligations of the Company to
the  Guarantor,  whether such debts and  obligations  now exist or are hereafter
incurred or arise,  or whether the  obligation be direct,  contingent,  primary,
secondary, several, joint and several, or otherwise, and irrespective of whether
such debts or  obligations  be evidenced by note,  contract,  open  account,  or
otherwise,  and  irrespective of the Person or Persons in whose favor such debts
or obligations may, at their inception,  have been, or may hereafter be created,
or the  manner in which  they  have been or may  hereafter  be  acquired  by the
Guarantor.  Except for  payments  permitted by the Credit  Agreement,  until the
Obligations  shall be paid and satisfied in full, the Aggregate  Commitments are
terminated  and  the  Guarantor  shall  have  performed  all of its  obligations
hereunder and the Loan Documents to which it is a party, the Guarantor shall not
receive or collect, directly or indirectly, from the Company any amount upon the
Guarantor Claims.

         Section  4.02  Claims  in  Bankruptcy.  In the  event of  receivership,
bankruptcy,  reorganization,  arrangement,  debtor's relief, or other insolvency
proceedings  involving the Company,  the  Administrative  Agent on behalf of the
Administrative  Agent and the Lenders  shall have the right to prove their claim
in any  proceeding,  so as to  establish  their  rights  hereunder  and  receive
directly  from the  receiver,  trustee or other court  custodian,  dividends and
payments which would otherwise be payable upon Guarantor  Claims.  The Guarantor
hereby assigns such dividends and payments to the  Administrative  Agent for the
benefit of the Administrative Agent and the Lenders.  Should any Agent or Lender
receive,  for  application  upon the  Obligations,  any such dividend or payment
which is otherwise  payable to the Guarantor,  and which, as between the Company
and the Guarantor,  shall  constitute a credit upon the Guarantor  Claims,  then
upon payment in full of the Obligations,  the Guarantor shall become  subrogated
to the rights of the  Administrative  Agent and the  Lenders to the extent  that
such  payments  to the  Administrative  Agent and the  Lenders on the  Guarantor
Claims have  contributed  toward the  liquidation of the  Obligations,  and such
subrogation  shall be with respect to that proportion of the  Obligations  which
would  have been  unpaid if the  Administrative  Agent and the  Lenders  had not
received dividends or payments upon the Guarantor Claims.

         Section 4.03 Payments Held in Trust. In the event that  notwithstanding
Sections 4.01 and 4.02, the Guarantor should receive any funds, payments, claims
or distributions which is prohibited by such Sections,  the Guarantor agrees (a)
to hold in trust for the Administrative Agent and the Lenders an amount equal to
the amount of all funds, payments,  claims or distributions so received, and (b)
that it shall



                                       -6-

have absolutely no dominion over the amount of such funds,  payments,  claims or
distributions  except to pay them promptly to the Administrative  Agent, for the
benefit of the Administrative Agent and the Lenders; and the Guarantor covenants
promptly to pay the same to the Administrative Agent.

         Section 4.04 Liens  Subordinate.  The Guarantor  agrees that, until the
Obligations are paid in full and the Aggregate Commitments terminated, any Liens
upon the Company's  assets securing payment of the Guarantor Claims shall be and
remain inferior and subordinate to any Liens upon the Company's  assets securing
payment of the Obligations,  regardless of whether such encumbrances in favor of
the Guarantor,  any Agent or Lender presently exist or are hereafter  created or
attach.  Without the prior  written  consent of the  Administrative  Agent,  the
Guarantor,  during the period in which any of the Obligations are outstanding or
the Aggregate  Commitments are in effect,  shall not (a) exercise or enforce any
creditor's right it may have against the Company,  or (b) foreclose,  repossess,
sequester  or  otherwise  take  steps or  institute  any  action  or  proceeding
(judicial or otherwise,  including  without  limitation the  commencement  of or
joinder  in any  liquidation,  bankruptcy,  rearrangement,  debtor's  relief  or
insolvency proceeding) to enforce any Lien, mortgages,  deeds of trust, security
interest,  collateral  rights,  judgments or other encumbrances on assets of the
Company held by the Guarantor.

         Section 4.05 Notation of Records.  All  promissory  notes and, upon the
request of the  Administrative  Agent, all accounts  receivable ledgers or other
evidence of the  Guarantor  Claims  accepted by or held by the  Guarantor  shall
contain a  specific  written  notice  thereon  that the  indebtedness  evidenced
thereby is subordinated under the terms of this Guaranty Agreement.

                                    ARTICLE V
                                  Miscellaneous

         Section 5.01  Successors  and Assigns.  This Guaranty  Agreement is and
shall be in every  particular  available  to the  successors  and assigns of the
Administrative  Agent and the Lenders and is and shall  always be fully  binding
upon  the  legal  representatives,  successors  and  assigns  of the  Guarantor,
notwithstanding  that some or all of the  monies,  the  repayment  of which this
Guaranty  Agreement  applies,  may be actually  advanced  after any  bankruptcy,
receivership,  reorganization or other event affecting either the Company or the
Guarantor.

         Section 5.02 Notices. Any notice or demand to the Guarantor under or in
connection with this Guaranty  Agreement may be given and shall  conclusively be
deemed and  considered  to have been given and received in the manner and to the
address of the Guarantor as provided for in the Credit Agreement.

         Section  5.03  Authority  of   Administrative   Agent.   The  Guarantor
acknowledges that the rights and  responsibilities  of the Administrative  Agent
under  this  Guaranty  Agreement  with  respect  to  any  action  taken  by  the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option,  right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Guaranty  Agreement shall, as between
the  Administrative  Agent and the Lenders,  be governed by the Credit Agreement
and by such other agreements with respect thereto as may exist from time to time
among them,  but, as between the  Administrative  Agent and the  Guarantor,  the
Administrative  Agent shall be  conclusively  presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting;  and
the Guarantor  shall not be under any obligation,  or  entitlement,  to make any
inquiry respecting such authority.

on the Obligations or proceeds of any collateral are  subsequently  invalidated,

been received and the  Administrative  Agent's and the Lenders'  Liens,  rights,
powers and remedies  under this Guaranty  Agreement and each Loan Document shall

reinstatement.

Agreement  is  subject  to the terms of the  Intercreditor  Agreement  which (a)
subjects  the ability of the Lender  Group to pursue  remedies  hereunder to the
prior  consent  of the  U.S.  Lenders  and (b)  sets  forth a  priority  for the
application of proceeds upon any disposition of amounts received hereunder.

         Section 2.01 Obligations  Guaranteed.  The Guarantor hereby irrevocably
and   unconditionally   guarantees   the  prompt  payment  at  maturity  of  the
Obligations.

         Section  2.02  Nature  of  Guaranty.  This  guaranty  is  an  absolute,
irrevocable,  completed and continuing guaranty of payment and not a guaranty of
collection,  and no notice of the Obligations or any extension of credit already
or  hereafter  contracted  by or extended  to the  Company  need be given to the
Guarantor.  The  guaranty  evidenced  hereby is joint and several with all other
guarantees of the Obligations. This guaranty may not be revoked by the Guarantor
and shall  continue to be effective  with respect to debt under the  Obligations
arising or created  after any  attempted  revocation  by the Guarantor and shall
remain in full force and effect until the  Obligations  are paid in full and the
Aggregate  Commit ments are terminated,  notwithstanding  that from time to time
prior thereto no Obligations may be outstanding. The Company, the Administrative
Agent and the Lenders may modify, alter, rearrange, extend for any period and/or
renew from time to time, the  Obligations and the  Administrative  Agent and the
Lenders  may waive any  Defaults  or Events  of  Default  without  notice to the
Guarantor and in such event the Guarantor  will remain fully bound  hereunder on
the  Obligations.  Subject to the terms of the Credit  Agreement,  this Guaranty
Agreement may be enforced by the Administrative Agent and/or the Lenders and any
subsequent  holder  of  the  Obligations  and  shall  not be  discharged  by the
assignment  or  negotiation  of all or part of the  Obligations.  The  Guarantor
hereby expressly waives presentment,  demand, notice of non-payment, protest and
notice of protest and dishonor,  notice of Event of Default, notice of intent to
accelerate the maturity and notice of acceleration of the maturity and any other
notice in connection with the Obligations, and also notice of acceptance of this
Guaranty Agreement,  acceptance on the part of the Administrative  Agent and the
Lenders being conclusively presumed by their request for this Guaranty Agreement
and delivery of the same to the Administrative Agent.

         Section  2.03  Lenders'  Rights.  Subject  to the  terms of the  Credit
Agreement,  the Guarantor authorizes the Lenders (or the Administrative Agent on
behalf of the  Lenders),  without  notice or demand and  without  affecting  the
Guarantor's obligation hereunder,  to take and hold agreed-upon security for the
payment of the Obligations,  and exchange,  enforce,  waive and release any such
security;  and to apply  such  security  and  direct the order or manner of sale
thereof as the  Administrative  Agent and the  Lenders in their  discretion  may
determine; and to obtain a guaranty of the Obligations from any one or more


                                        2

Persons and at any time or times to enforce, waive, rearrange,  modify, limit or
release any of such other Persons from their obligations under such guaranties.

         Section 2.04  Guarantor's  Waivers.  The Guarantor  waives any right to
require the  Administrative  Agent and the  Lenders to (a)  proceed  against the
Company or any other Person liable on the Obligations,  (b) enforce their rights
against any other  guarantor of the  Obligations,  (c) proceed or enforce  their
rights against or exhaust any security given to secure the Obligations, (d) have
the Company  joined with the  Guarantor in any suit arising out of this Guaranty
Agreement  and/or the  Obligations,  or (e) pursue any other remedy  whatsoever.
Neither the  Administrative  Agent nor the Lenders shall be required to mitigate
damages or take any action to reduce,  collect or enforce the  Obligations.  The
Guarantor  waives  any  defense  arising  by reason of any  disability,  lack of
corporate  authority  or power,  or other  defense  of the  Company or any other
guarantor of the  Obligations,  and shall remain  liable  hereon  regardless  of
whether the Company or any other  guarantor be found not liable  thereon for any
reason.

         Section 2.05 Maturity of  Obligations;  Payment.  The Guarantor  agrees
that  if the  maturity  of the  Obligations  is  accelerated  by  bankruptcy  or
otherwise,  such maturity  shall also be deemed  accelerated  for the purpose of
this Guaranty Agreement without demand or notice to the Guarantor. The Guarantor
will,  forthwith  upon notice  from the  Administrative  Agent of the  Company's
failure to pay the Obligations at maturity,  pay to the Administrative Agent for
the benefit of the  Administrative  Agent and the Lenders at the  Administrative
Agent's  Principal  Office,  the  amount  due  and  unpaid  by the  Company  and
guaranteed hereby.  The failure of the Administrative  Agent to give this notice
shall not in any way release the Guarantor hereunder.

         Section  2.06  Lenders'  Expenses.  If the  Guarantor  fails to pay the
Obligations after notice from the Administrative  Agent of the Company's failure
to pay any Obligations at maturity  (whether by acceleration or otherwise),  and
if the  Administrative  Agent or the Lenders  obtain the services of an attorney
for collection of amounts owing by the Guarantor hereunder,  or obtain advice of
counsel in respect of any of their rights under this Guaranty  Agreement,  or if
suit is filed to enforce this Guaranty  Agreement,  or if proceedings are had in
any bankruptcy, receivership or other judicial proceedings for the establishment
or collection of any amount owing by the Guarantor  hereunder,  or if any amount
owing by the  Guarantor  hereunder is collected  through such  proceedings,  the
Guarantor agrees to pay to the Administrative  Agent at its Principal Office the
reasonable attorneys' fees of the Administrative Agent and the Lenders.

         Section 2.07 Obligation.  It is expressly agreed that the obligation of
the  Guarantor  for the payment of the  Obligations  guaranteed  hereby shall be
primary and not secondary.

         Section 2.08 Events and  Circumstances  Not Reducing or Discharging the
Guarantor's Obligations. The Guarantor hereby consents and agrees to each of the
following to the fullest extent  permitted by law,  agrees that its  obligations
under this  Guaranty  Agreement  shall not be  released,  diminished,  impaired,
reduced or  adversely  affected by any of the  following,  and waives any rights

the Guarantor;

         (d)  Invalidity  of   Obligations.   The   invalidity,   illegality  or
unenforceability  of all or any part of the  Obligations  or any Loan  Document,

Loan Document) is illegal,  uncollectible,  legally impossible or unenforceable,

repayment of the  Obligations  shall not be properly  perfected  or created,  or
shall prove to be  unenforceable  or  subordinate  to any other  Lien,  it being
recognized  and agreed by the Guarantor  that the Guarantor is not entering into

action or omission prejudices the Guarantor or increases the likelihood that the
Guarantor will be required to pay the Obligations  pursuant to the terms hereof;
it being the  unambiguous  and  unequivocal  intention of the Guarantor that the
Guarantor  shall be obligated to pay the Obligations  when due,  notwithstanding
any occurrence,  circumstance,  event, action, or omission  whatsoever,  whether

described herein,  except for the full and final payment and satisfaction of the

by the Guarantor hereunder,  including without limitation,  any claim, remedy or
right  of   subrogation,   reimbursement,   exoneration,   indemnification,   or

Company. The Guarantor further waives any benefit of any right to participate in
any  security  now or  hereafter  held by the  Administrative  Agent  and/or the

Agent  and  the  Lenders  to  accept  this  Guaranty  Agreement,  the  Guarantor
represents  and  warrants  to  the  Lender  Group  (which   representations  and
warranties  will survive the creation of the  Obligations  and any  extension of
credit thereunder) that:

         (a) Benefit to the Guarantor.  The Company is a wholly-owned Subsidiary
of the  Guarantor;  and the  Guarantor's  guaranty  pursuant  to  this  Guaranty
Agreement  reasonably may be expected to benefit,  directly or  indirectly,  the
Guarantor;  and the Guarantor  has  determined  that this Guaranty  Agreement is
necessary  and  convenient  to the  conduct,  promotion  and  attainment  of the
business of the Guarantor and the Company.

         (b)  Solvency.  It (i) is not  insolvent as of the date hereof and will
not be  rendered  insolvent  as a  result  of  this  Guaranty  Agreement  or the
transactions  contemplated by the Credit Agreement or the making of the Loans or

or a transaction,  or about to engage in a business or a transaction,  for which
any Property or assets remaining

with the Guarantor  constitute  unreasonably  small capital,  and (iii) does not
intend to incur, or believe it will incur, debts that will be beyond its ability
to pay as such debts mature.

         (c) No Representation by Administrative  Agent or Lenders.  Neither any
Agent,  Lender nor any other  Person has made any  representation,  warranty  or
statement  to the  Guarantor  in order to induce the  Guarantor  to execute this
Guaranty Agreement.

                                   ARTICLE IV
                          SUBORDINATION OF INDEBTEDNESS

         Section 4.01 Subordination of All Guarantor Claims. As used herein, the
term  "Guarantor  Claims" shall mean all debts and obligations of the Company to
the  Guarantor,  whether such debts and  obligations  now exist or are hereafter
incurred or arise,  or whether the  obligation be direct,  contingent,  primary,
secondary, several, joint and several, or otherwise, and irrespective of whether
such debts or  obligations  be evidenced by note,  contract,  open  account,  or
otherwise,  and  irrespective of the Person or Persons in whose favor such debts
or obligations may, at their inception,  have been, or may hereafter be created,
or the  manner in which  they  have been or may  hereafter  be  acquired  by the
Guarantor.  Except for  payments  permitted by the Credit  Agreement,  until the
Obligations  shall be paid and satisfied in full, the Aggregate  Commitments are
terminated  and  the  Guarantor  shall  have  performed  all of its  obligations
hereunder and the Loan Documents to which it is a party, the Guarantor shall not
receive or collect, directly or indirectly, from the Company any amount upon the
Guarantor Claims.

         Section  4.02  Claims  in  Bankruptcy.  In the  event of  receivership,
bankruptcy,  reorganization,  arrangement,  debtor's relief, or other insolvency
proceedings  involving the Company,  the  Administrative  Agent on behalf of the
Administrative  Agent and the Lenders  shall have the right to prove their claim
in any  proceeding,  so as to  establish  their  rights  hereunder  and  receive
directly  from the  receiver,  trustee or other court  custodian,  dividends and
payments which would otherwise be payable upon Guarantor  Claims.  The Guarantor
hereby assigns such dividends and payments to the  Administrative  Agent for the
benefit of the Administrative Agent and the Lenders.  Should any Agent or Lender
receive,  for  application  upon the  Obligations,  any such dividend or payment
which is otherwise  payable to the Guarantor,  and which, as between the Company
and the Guarantor,  shall  constitute a credit upon the Guarantor  Claims,  then
upon payment in full of the Obligations,  the Guarantor shall become  subrogated
to the rights of the  Administrative  Agent and the  Lenders to the extent  that
such  payments  to the  Administrative  Agent and the  Lenders on the  Guarantor
Claims have  contributed  toward the  liquidation of the  Obligations,  and such
subrogation  shall be with respect to that proportion of the  Obligations  which
would  have been  unpaid if the  Administrative  Agent and the  Lenders  had not
received dividends or payments upon the Guarantor Claims.

         Section 4.03 Payments Held in Trust. In the event that  notwithstanding
Sections 4.01 and 4.02, the Guarantor should receive any funds, payments, claims
or distributions which is prohibited by such Sections,  the Guarantor agrees (a)
to hold in trust for the Administrative Agent and the Lenders an amount equal to
the amount of all funds, payments,  claims or distributions so received, and (b)
that it shall  have  absolutely  no  dominion  over the  amount  of such  funds,
payments,   claims  or  distributions   except  to  pay  them  promptly  to  the
Administrative  Agent,  for the  benefit  of the  Administrative  Agent  and the
Lenders;   and  the  Guarantor  covenants  promptly  to  pay  the  same  to  the
Administrative Agent.

         Section 4.04 Liens  Subordinate.  The Guarantor  agrees that, until the
Obligations are paid in full and the Aggregate Commitments terminated, any Liens
upon the Company's assets securing payment


                                        6

<PAGE>



of the  Guarantor  Claims shall be and remain  inferior and  subordinate  to any
Liens upon the Company's assets securing payment of the Obligations,  regardless
of whether  such  encumbrances  in favor of the  Guarantor,  any Agent or Lender
presently  exist or are hereafter  created or attach.  Without the prior written
consent of the Administrative  Agent, the Guarantor,  during the period in which
any of the  Obligations  are  outstanding  or the Aggregate  Commitments  are in
effect,  shall not (a)  exercise  or enforce  any  creditor's  right it may have
against the Company,  or (b) foreclose,  repossess,  sequester or otherwise take
steps or institute  any action or proceeding  (judicial or otherwise,  including
without   limitation  the   commencement  of  or  joinder  in  any  liquidation,
bankruptcy,  rearrangement, debtor's relief or insolvency proceeding) to enforce
any Lien,  mortgages,  deeds of trust,  security  interest,  collateral  rights,
judgments or other encumbrances on assets of the Company held by the Guarantor.

         Section 4.05 Notation of Records.  All  promissory  notes and, upon the
request of the  Administrative  Agent, all accounts  receivable ledgers or other
evidence of the  Guarantor  Claims  accepted by or held by the  Guarantor  shall
contain a  specific  written  notice  thereon  that the  indebtedness  evidenced
thereby is subordinated under the terms of this Guaranty Agreement.

                                    ARTICLE V
                                  MISCELLANEOUS

upon  the  legal  representatives,  successors  and  assigns  of the  Guarantor,

Guaranty  Agreement  applies,  may be actually  advanced  after any  bankruptcy,
receivership,  reorganization or other event affecting either the Company or the
Guarantor.

         Section 5.02 Notices. Any notice or demand to the Guarantor under or in
connection with this Guaranty  Agreement may be given and shall  conclusively be

address of the Guarantor as provided for in the Credit Agreement.

Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option,  right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Guaranty  Agreement shall, as between
the  Administrative  Agent and the Lenders,  be governed by the Credit Agreement
and by such other agreements with respect thereto as may exist from time to time
among them,  but, as between the  Administrative  Agent and the  Guarantor,  the
Administrative  Agent shall be  conclusively  presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting;  and
the Guarantor  shall not be under any obligation,  or  entitlement,  to make any
inquiry respecting such authority.

         Section 5.04 CONSTRUCTION.  THIS GUARANTY AGREEMENT (INCLUDING, BUT NOT
LIMITED TO, THE VALIDITY AND  ENFORCEABILITY  HEREOF)  SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE PROVINCE OF ALBERTA, CANADA.

on the Obligations or proceeds of any collateral are  subsequently  invalidated,
declared to be fraudulent or preferential, set aside

or required to be repaid to a trustee,  debtor in possession,  receiver or other
Person under any bankruptcy  law,  common law or equitable  cause,  then to such
extent,  the  Obligations so satisfied  shall be revived and continue as if such
payment or proceeds had not been received and the Administrative Agent's and the
Lenders' Liens,  rights,  powers and remedies under this Guaranty  Agreement and
each Loan Document shall continue in full force and effect.  In such event, each
Loan Document shall be  automatically  reinstated  and the Guarantor  shall take

Lenders to effect such reinstatement.

Agreement  is  subject  to the terms of the  Intercreditor  Agreement  which (a)

application of proceeds upon any disposition of amounts received hereunder.

         Section  5.07 Status as  Specified  Guarantor  Senior  Indebtedness  or
Designated Guarantor Senior Indebtedness.  The Guarantor hereby acknowledges and
confirms that:

                           Preferred  Stock  that  is  redeemed,   purchased  or
         retired by the  Corporation  shall assume the status of authorized  but
         unissued Preferred Stock and may thereafter,  subject to the provisions
         of any Directors'  Resolution providing for the issue of any particular
         series of Preferred Stock, be reissued in the same manner as authorized
         but unissued Preferred Stock.

                  (b) All shares of Common Stock shall be  identical  and except
         as otherwise required by law or as otherwise provided in the resolution
         or resolutions,  if any, adopted by the Board of Directors with respect
         to any series of Preferred Stock, the holders of the Common Stock shall
         exclusively  possess all voting  power,  and each share of Common Stock
         shall have one vote.

         person,  whether  or not the  Corporation  shall have  notice  thereof,
         except as expressly provided by applicable laws.

         5. The Board of  Directors  is hereby  authorized  to create and issue,
whether or not in  connection  with the issuance and sale of any of its stock or
other  securities,  rights  (the  "Rights")  entitling  the  holders  thereof to

                  (c) Provisions that adjust the number or exercise price of the
         Rights  or  amount  or  nature  of the  securities  or  other  property
         receivable  upon exercise of the Rights in the event of a  combination,
         split or  recapitalization  of any capital stock of the Corporation,  a
         change   in   ownership   of   the   Corporation's   securities   or  a
         reorganization,   merger,  consolidation,   sale  of  assets  or  other
         occurrence  relating to the  Corporation  or any  capital  stock of the
         Corporation,  and provisions restricting the ability of the Corporation
         to enter into any such  transaction  absent an  assumption by the other
         party or parties thereto of the  obligations of the  Corporation  under
         such Rights;

                  (d) Provisions that deny the holder of a specified  percentage
         of the outstanding  securities of the Corporation the right to exercise
         the Rights and/or cause the Rights held by such holder to become void;

                  (e)  Provisions  that  permit  the  Corporation  to redeem the
         Rights; and

                  (f) The  appointment  of a Rights  Agent  with  respect to the
         Rights;

                  and such  other  provisions  relating  to the Rights as may be
         determined by the Board of Directors.

         6. No holder of stock of the  Corporation  shall be entitled as a right
to purchase or subscribe for any part of any unissued  stock of the  Corporation
or any additional stock to be issued by reason of any increase of the authorized
capital stock of the  Corporation,  or any bonds,  certificates of indebtedness,
debentures  or  other  securities  convertible  into  stock  or such  additional
authorized  issue of new stock,  but rather such stock,  bonds,  certificates of
indebtedness, debentures


                                       -3-

and other securities may be issued and disposed of pursuant to resolution of the
Board of Directors to such persons,  firms,  corporations or  associations,  and
upon such  terms as may be deemed  advisable  by the Board of  Directors  in the
exercise of their discretion.

         7. The  following  provisions  are inserted for the  management  of the
business  and  for  the  conduct  of the  affairs  of the  Corporation,  and for
creating,  defining, limiting and regulating the powers of the Corporation,  the
directors and the stockholders.

                  (a) Subject to any  limitation  contained  in the bylaws,  the
         Board of Directors  may make  bylaws,  and from time to time may alter,
         amend  or  repeal  any  bylaws,  but any  bylaws  made by the  Board of
         Directors may be altered,  amended or repealed by the  stockholders  at
         any meeting of stockholders  by the affirmative  vote of the holders of
         at least 66 2/3% of the outstanding  shares  entitled to vote  thereon,
         provided notice that an amendment is to be considered and acted upon is
         inserted in the notice or waiver of notice of such meeting.

                  (b)  Any  vote  or  votes   authorizing   liquidation  of  the
         Corporation or proceedings for its dissolution may provide,  subject to
         (i) any agreements among and between  stockholders,  (ii) the rights of
         creditors and (iii) rights expressly provided for particular classes or
         series of stocks, for the  distribution pro rata among the stockholders
         of the Corporation of assets of the  Corporation,  wholly or in part in
         kind,  whether  such  assets  be in cash  or  other  property,  and may
         authorize  the Board of Directors of the  Corporation  to determine the
         value of the  different  assets of the  Corporation  for the purpose of
         such liquidation and may divide, or authorize the Board of Directors of
         the  Corporation  to divide,  such assets or any part thereof among the
         stockholders of the  Corporation in such manner that every  stockholder
         will receive a proportionate  amount in value (determined as aforesaid)
         of cash  or  property  of the  Corporation  upon  such  liquidation  or
         dissolution  even  though each  stockholder  may not receive a strictly
         proportionate part of each such asset.

                  (c) The  Corporation  shall,  to the maximum extent  permitted
         from time to time  under the  General  Corporation  Law of the State of
         Delaware,  indemnify  and upon request  shall  advance  expenses to any
         person who is or was a party or is threatened to be made a party to any
         threatened,  pending or completed  action,  suit,  proceeding or claim,
         whether civil, criminal,  administrative or investigative, by reason of
         the fact that he is or was or has agreed to be a director or officer of
         the  Corporation,  or while a director  or officer is or was serving at
         the  request of the  Corporation  as a director,  officer,  employee or
         agent of another  corporation,  partnership,  joint  venture,  trust or
         other  enterprise,  including  service with respect to employee benefit
         plans,  against  expenses  (including  attorneys'  fees and  expenses),
         judgments,  fines, penalties and amounts paid in settlement or incurred
         in connection with the investigation,  preparation to defend or defense
         of such action, suit, proceeding, claim or counterclaim initiated by or
         on behalf of such person. Such  indemnification  shall not be exclusive
         of other  indemnification  rights  arising under any bylaw,  agreement,
         vote of directors or  stockholders  or otherwise and shall inure to the
         benefit  of the heirs and legal  representatives  of such  person.  Any
         repeal or modification of the foregoing provisions of


                                       -4-

<PAGE>



         this Section 7(c) shall not adversely affect any right or protection of
         a director or officer of the  Corporation  existing at the time of such
         repeal or modification.

                  (d) A  director  of the  Corporation  shall not be  personally
         liable to the Corporation or its  stockholders for monetary damages for
         breach of fiduciary  duty as a director,  except for  liability (i) for
         any breach of the director's  duty of loyalty to the corporation or its
         stockholders,  (ii) for acts or  omissions  not in good  faith or which
         involve  intentional  misconduct or a knowing  violation of law,  (iii)
         under  Section  174 of the  General  Corporation  Law of the  State  of
         Delaware,  or (iv) for any transaction  from which the director derived
         an improper  personal  benefit.  If the General  Corporation Law of the
         State of  Delaware is amended to  authorize  corporate  action  further
         eliminating or limiting the personal  liability of directors,  then the
         liability  of a director  of the  Corporation  shall be  eliminated  or
         limited to the fullest extent permitted by the General  Corporation Law
         of the State of Delaware,  as so amended. Any repeal or modification of
         this  Section  by  the   stockholders  of  the  Corporation   shall  be
         prospective  only, and shall not adversely affect any limitation on the
         personal  liability  of a director of the  Corporation  existing at the
         time of such repeal or modification.

         8. Subject to the rights of the holders of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation to
elect additional directors under specific circumstances:

                  (a) any  action  required  or  permitted  to be  taken  by the
         stockholders  of the  Corporation  must be  effected  at a duly  called
         annual or special  meeting of  stockholders  of the Corporation and may
         not be effected by any consent in writing of such stockholders;

                  (b) special  meetings of the  stockholders  of the Corporation
         may be called only by the Chairman of the Board of Directors  and shall
         be called within ten (10) days after receipt of the written  request of
         the Board of Directors, pursuant to a resolution approved by a majority
         of the whole Board of Directors; and

                  (c) the  business  permitted  to be  conducted  at any special
         meeting of the  stockholders  is limited to the business brought before
         the  meeting by the  Chairman or by the  Secretary  at the request of a
         majority of the Board of Directors.

         9. The number of directors which shall constitute the whole board shall
be such as from time to time  shall be fixed by, or in the manner  provided  in,
the  bylaws,  but in no case shall the number be less than two nor more than 15.
The names  and the  addresses  of the  persons  who are to serve as the  initial
directors of the  Corporation  until the first annual meeting of stockholders or
until their successors are elected or qualified are:

          James C. Flores                 8440 Jefferson Highway, Suite 420
                                          Baton Rouge, LA 70809

          William W. Rucks, IV            500 Dover Boulevard, Suite 300
                                          Lafayette, LA 70503

                  The directors shall be classified with respect to the time for
which they shall  severally  hold  office by dividing  them into three  classes,
which classes shall consist of an equal, or as near to equal as possible, number
of  directors.  At the 1995  annual  meeting of  stockholders,  the  director or
directors of the first  class shall be elected  for a term  expiring at the next
annual meeting of  stockholders to be held in 1996; the director or directors of
the second class for a term  expiring at the annual  meeting to be held in 1997;
and the  director or  directors  of the third  class for a term  expiring at the
annual meeting to be held in 1998. At each annual  meeting,  commencing with the
annual  meeting in 1996,  the  successor or successors to the class of directors
whose  term shall  expire in that year  shall be elected to hold  office for the
term of three years,  so that the term of office of one class of directors shall
expire in each  year.  Any  increase  or  decrease  in the  number of  directors
constituting the Board shall be apportioned  among the classes so as to maintain
the number of directors in each class as near as possible to one-third the whole
number of directors as so adjusted.  Any director elected or appointed to fill a
vacancy  shall  hold  office for the  remaining  term of the class to which such
directorship  is assigned.  No decrease in the number of directors  constituting
the  Corporation's  Board of Directors  shall  shorten the term of any incumbent
director. Any vacancy in the Board of Directors,  whether arising through death,
resignation  or removal of a  director,  or through an increase in the number of
directors of any class,  shall be filled by the majority  vote of the  remaining
directors.  The bylaws may contain any provision regarding classification of the
Corporation's  directors not  inconsistent  with the terms hereof.  The right to
cumulate votes in the election of directors is expressly prohibited.

                  A director of the  Corporation  may be removed  only for cause
and  only  upon  the  affirmative  vote  of the  holders  of a  majority  of the
outstanding capital stock of the Corporation  entitled to vote at an election of
directors,  subject to further  restrictions on removal,  not inconsistent  with
this Section 9, as may be contained in the bylaws.

                  Notwithstanding the foregoing, whenever the holders of any one
or more classes or series of Preferred  Stock  issued by the  Corporation  shall
have the right,  voting  separately by class or series, to elect directors at an
annual or special meeting of stockholders, the election, term of office, filling
of vacancies and other features of such  directorships  shall be governed by the
terms  of  this  Certificate  of  Incorporation  applicable  thereto,  and  such
directors so elected shall not be divided into classes  pursuant to this Section
9 unless expressly provided by such terms.

         10.  Election of  directors  need not be by written  ballot  unless the
bylaws of the Corporation shall so provide. Meetings of stockholders may be held
within or without the State of Delaware, as the bylaws may provide. The books of
the Corporation  may be (subject to any provisions  contained in the statutes of
the State of Delaware) outside the State of Delaware at such


                                       -6-

<PAGE>



place or places as may be designated from time to time by the Board of Directors
or the bylaws of the Corporation.

         11.  The  Corporation  reserves  the right to amend,  alter,  change or
repeal any  provision  contained in this  Certificate  of  Incorporation  in the
manner  set  forth  below,  and all  rights  conferred  upon  the  directors  or
stockholders  of the Corporation  herein or in any amendment  hereof are granted
subject to this reservation.

                  The  affirmative  vote of the  holders  of at least 75% of the
then outstanding shares entitled to vote thereon and the affirmative vote of the
holders of at least 75% of the then outstanding shares of each class of stock of
the  Corporation  voting  separately as a class,  shall be required to adopt any
amendment to Sections 5, 7, 8, 9 and 11 of the Certificate of  Incorporation  of
the Corporation.

                  The affirmative  vote of the holders of at least a majority of
the then outstanding shares entitled to vote thereon and the affirmative vote of
the holders of at least a majority of the then outstanding  shares of each class
of stock of the Corporation  voting separately as a class,  shall be required to
adopt any  amendment  to  Sections  1, 2, 3, 4, 6 and 10 of the  Certificate  of
Incorporation of the Corporation.

         12. The name and mailing address of the incorporator is:

September, 1994.

                      ------------------------------------


         Ocean  Energy,  Inc., a corporation  organized  and existing  under the
General  Corporation  Law of the  State  of  Delaware  (hereinafter  called  the
"Company"), hereby certifies that the following resolutions were duly adopted by
the Board of  Directors of the Company as required by Section 151 of the General
Corporation  Law of the State of Delaware  at a meeting  duly called and held on
December 22, 1997:

         WHEREAS,  pursuant to the Company's  Certificate of  Incorporation,  as
amended to date  (hereinafter  called the "Certificate of  Incorporation"),  the
Company is authorized to issue up to 10,000,000  shares of preferred  stock, par
value $0.01 per share (the  "Preferred  Stock") from time to time, none of which
are currently outstanding; and

         WHEREAS,  pursuant to the authority vested in the Board of Directors of
the  Company in  accordance  with the  General  Corporation  Law of the State of
Delaware and the Company's Certificate of Incorporation,  the Board of Directors
is authorized by resolution duly adopted, to designate shares of Preferred Stock
to be issued, in one or more series,  to provide for the designation  thereof of
the powers, designations,  preferences and relative, participating,  optional or
other  special  rights of the  shares of such  series,  and the  qualifications,
limitations or restrictions thereof;

         RESOLVED,  that the form of  Certificate  of  Designation  of  Series A
Junior Participating  Preferred Stock (the "Certificate of Designation"),  dated
December 22, 1997,  which was previously  furnished to the members of this Board
for their review, is hereby approved in all respects; and

         RESOLVED  FURTHER,  that the  President or any Vice  President  and the
Secretary  or any  Assistant  Secretary  of the  Company be, and each hereby is,
authorized and  empowered,  for and on behalf of the Company and in its name, to
execute and deliver the  Certificate  of  Designation,  in the form presented to

Secretary  or any  Assistant  Secretary  Vice of the Company is  authorized  and
empowered, in the name and on behalf

<PAGE>



of the Company,  to file the  Certificate of  Designation  with the Secretary of
State of the State of Delaware  and such other  offices of the State of Delaware
as may be necessary or appropriate; and

         RESOLVED FURTHER, that pursuant to the authority vested in the Board of
Directors of the  Corporation in accordance  with the provisions of the Delaware
General Corporation Law and the Certificate of Incorporation,  a Series A Junior
Participating  Preferred  Stock  of  the  Corporation  is  hereby  created,  and
2,000,0000  shares of preferred stock shall be reserved for issuance as Series A
Junior  Participating  Preferred  Stock in accordance  with the  Certificate  of
Designation  with  the  designations  thereof  and  the  powers,   designations,
preferences and relative, participating, optional or other special rights of the
shares of such  series,  and the  qualifications,  limitations  or  restrictions
thereof as set forth below:

         Section 1.  Designation and Amount.  The shares of such series shall be
designated  as "Series A Junior  Participating  Preferred  Stock" (the "Series A
Preferred  Stock") and the number of shares  constituting the Series A Preferred
Stock shall be 2,000,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors;  provided,  that no decrease  shall reduce
the  number  of shares of  Series A  Preferred  Stock to a number  less than the
number of shares  then  outstanding  plus the  number  of  shares  reserved  for
issuance upon the exercise of  outstanding  options,  rights or warrants or upon
the conversion of any outstanding  securities issued by the Company  convertible
into Series A Preferred Stock.

         Section 2.  Dividends and Distributions.

         (A) Subject to the rights of the holders of any shares of any series of
Preferred  Stock of the Company (the  "Preferred  Stock") (or any similar stock)
ranking  prior and  superior  to the Series A  Preferred  Stock with  respect to
dividends,  the holders of shares of Series A Preferred  Stock, in preference to
the  holders of Common  Stock,  par value $0.01 per share,  of the Company  (the
"Common  Stock")  and of any other stock of the  Company  ranking  junior to the
Series A Preferred Stock, shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds  legally  available  therefor,  quarterly
dividends payable in cash on the last day of January,  April,  July, and October
in each year (each such date being  referred  to herein as a  "Dividend  Payment
Date"),  commencing on the first Dividend  Payment Date after the first issuance
of a share or fraction of a share of Series A Preferred  Stock, in an amount per
share  (rounded to the  nearest  cent) equal to the greater of (a) $1.00 and (b)
subject to the provision for  adjustment  hereinafter  set forth,  100 times the
aggregate  per share amount of all cash  dividends,  and 100 times the aggregate
per  share  amount  (payable  in  kind)  of  all  non-cash  dividends  or  other
distributions other than a dividend payable in shares of Common Stock,  declared
on the Common Stock since the immediately  preceding  Dividend  Payment Date or,
with respect to the first Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Preferred  Stock. In the event that the
Company  shall at any time after  January 9, 1998 declare or pay any dividend on
the Common Stock payable in shares of Common Stock,  or effect a subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case


                                       -2-

<PAGE>



the amount to which holders of shares of Series A Preferred  Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction,  the numerator of which is
the number of shares of Common Stock  outstanding  immediately  after such event
and the  denominator  of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         (B) The Company shall declare a dividend or  distribution on the Series
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it  declares a  dividend  or  distribution  on the Common  Stock  (other  than a
dividend  payable in shares of Common  Stock);  provided  that,  in the event no
dividend or distribution shall have been declared on the Common Stock during the
period  between  any  Dividend  Payment  Date and the next  subsequent  Dividend
Payment  Date,  a dividend  of $1.00 per share on the Series A  Preferred  Stock
shall  nevertheless  be payable,  when, as and if declared,  on such  subsequent
Dividend Payment Date.

         (C) Dividends  shall begin to accrue and be cumulative,  whether or not
earned or declared,  on outstanding  shares of Series A Preferred Stock from the
Dividend  Payment Date next  preceding the date of issue of such shares,  unless
the date of issue of such  shares  is  prior to the  record  date for the  first
Dividend  Payment  Date,  in which case  dividends on such shares shall begin to
accrue from the date of issue of such  shares,  or unless the date of issue is a
Dividend  Payment Date or is a date after the record date for the  determination
of holders of shares of Series A Preferred Stock entitled to receive a quarterly
dividend and before such  Dividend  Payment Date, in either of which events such
dividends  shall begin to accrue and be cumulative  from such  Dividend  Payment
Date.  Accrued but unpaid  dividends shall not bear interest.  Dividends paid on
the shares of Series A Preferred  Stock in an amount less than the total  amount
of such  dividends  at the time  accrued  and  payable on such  shares  shall be
allocated pro rata on a  share-by-share  basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred  Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

         Section 3. Voting  Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment  hereinafter  set forth and
except as otherwise  provided in the Certificate of Incorporation or required by
law, each share of Series A Preferred  Stock shall entitle the holder thereof to
100 votes on all  matters  upon which the  holders  of the  Common  Stock of the
Company are entitled to vote.  In the event the Company  shall at any time after
January 9, 1998  declare or pay any  dividend  on the  Common  Stock  payable in
shares of Common Stock, or effect a subdivision or combination or  consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by  payment of a dividend  in shares of Common  Stock)  into a greater or lesser
number of shares of Common Stock, then in each such case the number of votes per
share to which  holders  of shares of Series A  Preferred  Stock  were  entitled
immediately  prior to such event shall be adjusted by multiplying such number by
a fraction, the


                                       -3-

<PAGE>



numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

         (B)  Except  as  otherwise  provided  herein,  in  the  Certificate  of
Incorporation or in any other  Certificate of Designations  creating a series of
Preferred Stock or any similar stock,  and except as otherwise  required by law,
the holders of shares of Series A  Preferred  Stock and the holders of shares of
Common Stock and any other capital stock of the Company  having  general  voting
rights  shall vote  together as one class on all matters  submitted to a vote of
stockholders of the Company.

         (C) Except as set forth herein, or as otherwise  provided by law or the
Certificate of Incorporation,  holders of Series A Preferred Stock shall have no
special  voting rights and their  consent  shall not be required  (except to the
extent  they are  entitled  to vote with  holders  of Common  Stock as set forth
herein) for taking any corporate action.

         Section 4.  Certain Restrictions.

         (A) Whenever  quarterly  dividends or other dividends or  distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not earned or  declared,  on shares of Series A Preferred  Stock  outstanding
shall have been paid in full, the Company shall not:

                  (i) declare or pay dividends, or make any other distributions,
         on any shares of stock ranking junior (as to dividends) to the Series A
         Preferred Stock;

                  (ii)   declare   or  pay   dividends,   or  make   any   other
         distributions,  on any  shares  of stock  ranking  on a  parity  (as to
         dividends)  with the Series A Preferred  Stock,  except  dividends paid
         ratably on the Series A Preferred  Stock and all such  parity  stock on
         which  dividends  are payable or in arrears in  proportion to the total
         amounts to which the holders of all such shares are then entitled;

                  (iii)   redeem  or   purchase   or   otherwise   acquire   for
         consideration  shares  of  any  stock  ranking  junior  (either  as  to
         dividends or upon liquidation, dissolution or winding up) to the Series
         A Preferred  Stock,  provided  that the Company may at any time redeem,
         purchase  or  otherwise  acquire  shares  of any such  junior  stock in
         exchange for shares of any stock of the Company  ranking  junior (as to
         dividends  and upon  dissolution,  liquidation  or  winding  up) to the
         Series A Preferred Stock or rights, warrants or options to acquire such
         junior stock;

                  (iv) redeem or purchase or otherwise acquire for consideration
         any shares of Series A Preferred  Stock, or any shares of stock ranking
         on a parity (either as to dividends or upon liquidation, dissolution or
         winding up) with the Series A  Preferred  Stock,  except in  accordance
         with a purchase offer made in writing or by publication  (as determined
         by the Board of  Directors)  to all  holders of such  shares  upon such
         terms as the Board of Directors,


                                       -4-

<PAGE>



         after  consideration of the respective  annual dividend rates and other
         relative rights and  preferences of the respective  series and classes,
         shall  determine  in good  faith  will  result  in fair  and  equitable
         treatment among the respective series or classes.

         (B) The  Company  shall not permit  any  subsidiary  of the  Company to
purchase  or  otherwise  acquire  for  consideration  any shares of stock of the
Company  unless  the  Company  could,  under  paragraph  (A) of this  Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

         Section 5.  Reacquired  Shares.  Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and canceled  promptly after the  acquisition  thereof.  All such shares
shall upon their retirement  become  authorized but unissued shares of Preferred
Stock  and may be  reissued  as part of a new  series of  Preferred  Stock to be
created by resolution or resolutions  of the Board of Directors,  subject to any
conditions and restrictions on issuance set forth herein.

         Section  6.   Liquidation,   Dissolution   or  Winding   Up.  Upon  any
liquidation,  dissolution or winding up of the Company, no distribution shall be
made (A) to the  holders of the Common  Stock or of shares of any other stock of
the Company ranking junior, upon liquidation,  dissolution or winding up, to the
Series A Preferred Stock unless,  prior thereto, the holders of shares of Series
A Preferred  Stock shall have received $1.00 per share,  plus an amount equal to
accrued  and unpaid  dividend  distributions  thereon,  whether or not earned or
declared,  to the date of such  payment,  provided that the holders of shares of
Series A Preferred  Stock shall be entitled to receive an  aggregate  amount per
share,  subject to the provision for adjustment  hereinafter set forth, equal to
100 times the aggregate  amount to be distributed per share to holders of shares
of Common  Stock,  or (B) to the holders of shares of stock  ranking on a parity
upon  liquidation,  dissolution or winding up with the Series A Preferred Stock,
except  distributions  made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled  upon such  liquidation,  dissolution  or winding up. In the
event, however, that there are not sufficient assets available to permit payment
in  full  of the  Series  A  Preferred  Stock  liquidation  preference  and  the
liquidation preferences of all other classes and series of stock of the Company,
if any,  that rank on a parity  with the  Series A  Preferred  Stock in  respect
thereof,  then the assets available for such  distribution  shall be distributed
ratably to the holders of the Series A  Preferred  Stock and the holders of such
parity shares in the proportion to their respective liquidation preferences.  In
the event the Company shall at any time after January 9, 1998 declare or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  aggregate  amount to which  holders of shares of Series A
Preferred Stock were entitled  immediately prior to such event under the proviso
in clause (A) of the preceding  sentence shall be adjusted by  multiplying  such
amount by a fraction  the  numerator  of which is the number of shares of Common
Stock outstanding immediately after such


                                       -5-

<PAGE>



event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

         Section 7.  Consolidation,  Merger,  etc. In the case the Company shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common Stock are  converted  into,  exchanged  for or changed into
other stock or securities,  cash and/or any property, then in any such case each
share of Series A Preferred Stock shall at the same time be similarly  converted
into,  exchanged  for or  changed  into an  amount  per  share  (subject  to the
provision for adjustment hereinafter set forth) equal to 100 times the aggregate
amount of stock,  securities,  cash and/or any other property (payable in kind),
as the case may be,  into  which or for  which  each  share of  Common  Stock is
converted,  exchanged or  converted.  In the event the Company shall at any time
after January 9, 1998 declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or  consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by  payment of a dividend  in shares of Common  Stock)  into a greater or lesser
number of shares of Common Stock, then in each such case the amount set forth in
the  preceding  sentence with respect to the  conversion,  exchange or change of
shares of Series A Preferred Stock shall be adjusted by multiplying  such amount
by a fraction,  the  numerator  of which is the number of shares of Common Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         Section 8. No Redemption.  The shares of Series A Preferred Stock shall
not be redeemable from any holder.

         Section 9. Rank. The Series A Preferred  Stock shall rank, with respect
to the payment of dividends  and the  distribution  of assets upon  liquidation,
dissolution  or  winding  up of the  Company,  junior  to all  other  series  of
Preferred Stock and senior to the Common Stock.

         Section 10. Amendment.  If any proposed amendment to the Certificate of
Incorporation  (including this Certificate of Designations)  would alter, change
or repeal any of the preferences, powers or special rights given to the Series A
Preferred Stock so as to affect the Series A Preferred Stock adversely, then the
holders of the Series A Preferred  Stock shall be entitled to vote separately as
a class upon such  amendment,  and the  affirmative  vote of  two-thirds  of the
outstanding  shares of the Series A  Preferred  Stock,  voting  separately  as a
class,  shall be necessary for the adoption  thereof,  in addition to such other
vote as may be required by the General Corporation Law of the State of Delaware.

         Section 11. Fractional  Shares.  Series A Preferred Stock may be issued
in fractions of a share that shall  entitle the holder,  in  proportion  to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate  in  distributions  and to have the  benefit of all other  rights of
holders of Series A Preferred Stock.

brief  description  of the  business  desired  to be  brought  before the annual
meeting and the reasons for conducting such business at the annual meeting,  (b)
the  name  and  address,  as they  appear  on the  Corporation's  books,  of the
stockholder  proposing such business,  (c) the class and number of shares of the
Corporation  which  are  beneficially  owned  by the  stockholder,  and  (d) any
material interest of the stockholder in such business.  Notwithstanding anything
in the Bylaws to the  contrary,  no  business  shall be  conducted  at an annual
meeting except in accordance with the procedures set forth in this Section 3.

presiding officer should so determine, the presiding officer shall so declare to
the meeting and any such business not properly  brought before the meeting shall
not be transacted.

                  Section 4. The officer  who has charge of the stock  ledger of

stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any  stockholder,  for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting,  either at a place within the city where the
meeting  is to be held,  which  place  shall be  specified  in the notice of the
meeting, or, if not so specified,  at the place where the meeting is to be held.
The list shall also be  produced  and kept at the time and place of the  meeting
during the whole time thereof,  and may be inspected by any  stockholder  who is
present.

                  Section  5.  Special  meetings  of the  stockholders  for  any
purpose may be called only by the Chairman of the Board of  Directors  and shall

Directors,  pursuant to a resolution  approved by a majority of the entire Board
of Directors.  The business  permitted to be conducted at any special meeting of
the  stockholders  is limited to the business  brought before the meeting by the
Chairman or by the Secretary at the request of a majority of the entire Board of
Directors.

                  Section 6.  Written  notice of a special  meeting  stating the

represented at any meeting of the  stockholders,  the  stockholders  entitled to
vote thereat,  present in person or  represented  by proxy,  shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.

                  Section 8. When a meeting  is  adjourned  to  another  time or
place,  notice need not be given of the adjourned  meeting,  except as otherwise
required by this Section 8, if the time and place  thereof are  announced at the
meeting  at which  the  adjournment  is taken.  At such  adjourned  meeting  the
Corporation  may transact any business  which might have been  transacted at the
original  meeting.  If the  adjournment is for more than thirty (30) days, or if
after the  adjournment a new record date is fixed for the adjourned  meeting,  a
notice of the  adjourned  meeting shall be given to each  stockholder  of record
entitled to vote at the meeting.

                  Section 9. When a quorum is present at any  meeting,  the vote
of the holders of a majority of the stock having  voting power present in person
or represented  by proxy shall decide any question  brought before such meeting,
except as provided to the  contrary by statute,  the  Company's  certificate  of
incorporation or these Bylaws.

                  Section 1. The number of Directors shall be fixed from time to

persons.   The  Directors  shall  be  elected  at  the  annual  meeting  of  the
stockholders in accordance with the provisions of Section 2 of this Article, and
each  Director  elected  shall hold office  until his  successor  is elected and
qualified. Directors need not be stockholders.

                  Section  2.  Subject  to the rights of holders of any class or
series of stock  having a  preference  over the Common  Stock as to dividends or
upon  liquidation,  nominations for the election of Directors may be made by the
Board of Directors or a committee  appointed by the Board of Directors or by any
stockholder  entitled  to vote  in the  election  of  Directors  generally.  Any
stockholder entitled to vote in the election of Directors generally may nominate
one or more  persons for  election  as  Directors  at a meeting  only if written
notice of such  stockholder's  intent to make such nomination or nominations has
been  given,  either by  personal  delivery or by United  States  mail,  postage
prepaid, to the secretary of the Corporation not later than 80 days prior to the
date of any annual or special meeting. In the event that the date of such annual
or special meeting was not publicly  announced by the Corporation by mail, press
release  or  otherwise  more than 90 days  prior to the  meeting,  notice by the
stockholder  to be timely must be delivered to the secretary of the  Corporation
not later than the close of business on the tenth day following the day on which
such   announcement  of  the  date  of  the  meeting  was  communicated  to  the
stockholders.

                  Each such notice shall set forth:  (a) the name and address of
the  stockholder who intends to make the nomination and of the person or persons
to be nominated; (b) a representation that the stockholder is a holder of record
of stock of the  Corporation  entitled  to vote at such  meeting  and intends to

specified in the notice; (c) a description of all arrangements or understandings
between the stockholder and each nominee and any other person or persons (naming
such person or persons)  pursuant to which the nomination or nominations  are to
be made by the stockholder;  (d) such other  information  regarding each nominee
proposed  by such  stockholder  as would be  required  to be included in a proxy
statement  filed  pursuant to the proxy  rules of the  Securities  and  Exchange
Commission had the nominee been nominated,  or intended to be nominated,  by the
Board of  Directors;  and (e) the consent of each nominee to serve as a Director
of the Corporation if so elected.

                  If the  presiding  officer of the meeting for the  election of
Directors  determines  that a  nomination  of any  candidate  for  election as a
Director  at  such  meeting  was not  made in  accordance  with  the  applicable
provisions of these Bylaws, such nomination shall be void.

                  Section 3.  Subject to the rights of the  holders of any class
or series of stock having a preference  over the Common Stock as to dividends or
upon  liquidation to elect additional  Directors under specified  circumstances,
newly  created  directorships  resulting  from any  increase  in the  number  of
Directors  and any  vacancy  on the Board of  Directors  resulting  from  death,
resignation,  disqualification, removal or other cause shall be filled solely by
the  affirmative  vote of a majority of the remaining  Directors then in office,
even though less than a quorum of the Board of Directors, or by a sole remaining
Director.  Any Director  elected or chosen as provided  herein shall hold office
until the sooner of the following events:  (i) the expiration of the term of the
directorship  to which he is  appointed,  (ii)  such  time as his  successor  is
elected and qualified or (iii) his  resignation  or removal.  No decrease in the
number of Directors  constituting  the Board of Directors shall shorten the term
of an incumbent Director.

or series of stock  having  preference  over the Common Stock as to dividends or
upon  liquidation to elect additional  Directors under specified  circumstances,
any Director may be removed  from office only for cause by the  stockholders  in
the manner provided in this Section 4. At any annual meeting of the stockholders
of the  Corporation  or at  any  special  meeting  of  the  stockholders  of the
Corporation,  the notice of which  shall state that the removal of a Director or
Directors  is among the  purposes of the meeting,  the  affirmative  vote of the
holders  of at  least  662/3  percent  of  the  combined  voting  power  of  the
outstanding  shares of Voting  Stock (as defined  below),  voting  together as a
single class, may remove such Director or Directors for cause.

                  For the purpose of this Section 4,  "Voting  Stock" shall mean
the  outstanding  shares of capital  stock of the  Corporation  entitled to vote
generally in the election of Directors.  In any vote required by or provided for
in this  Section  4, each share of Voting  Stock  shall have the number of votes
granted to it generally in the election of Directors.
