SECTION II. PURPOSE OF THE PLAN.

         The Company desires to effect a program of making awards as soon as

employees of the Company and its subsidiaries, Christensen Boyles Corporation,
Boyles Bros. Drilling Company and Layne Christensen Canada Limited, who during
such fiscal year, in the judgment of the Committee have significantly
contributed to the achievement of certain objectives of the Company and of the
District within the Company in which such employees perform services. The
purpose of this program is to provide additional incentive for the eligible
employees to promote the best interests and most profitable operation of the
Company.

         This program shall be known as the "Layne Christensen Company District
Incentive Compensation Plan" (hereinafter referred to as the "Plan"). This Plan
amends and supersedes the Layne Christensen Company District Incentive
Compensation Plan previously approved and adopted by the board of directors on

the Plan shall not be in lieu of or otherwise affect or be affected by any other
compensation plan or arrangement of the Company.

SECTION III. ADMINISTRATION.

         The Plan shall be administered by the Committee. The Committee shall
consist of at least three persons appointed by the Board of Directors of the
Company. During the one-year period prior to the commencement of service of a
Committee member on the Committee, such member shall not have participated in,
and while serving and for one year after serving on the Committee, such member
shall not be eligible for participation in, the Plan.

         The Committee shall have full power, in its sole discretion, to
interpret, construe and administer the Plan and adopt rules and regulations
relating to the Plan.

         Decisions made by the Committee in good faith and in the exercise of
its powers and duties hereunder shall be binding upon all parties concerned. No
member of the Committee shall be liable to anyone for any action taken or
decision made in good faith pursuant to the power or discretion vested in such
person under the Plan.

                                       2

SECTION IV. PARTICIPATION.

         All salaried, non-clerical employees, other than corporate general and
administrative employees and Integrated Groundwater Services Division employees
responsible for business development, shall be eligible for participation in the
Plan (and shall hereinafter be referred to as "Participants").

         In addition to the Participants and at the discretion of the
Administrative Committee, or the District/Branch Manager with the concurrence of
the operating vice president responsible for the District, a portion of the
award payable hereunder may be set aside for payment to employees who do not
participate in any other Company bonus or incentive program.

SECTION V. CALCULATION OF BENCHMARKS.

         The incentive compensation of each Participant and the Pool for each
District shall be calculated based on certain performance benchmarks. Each
fiscal year, each District will be assigned a Revenue Benchmark and an EBIT
Benchmark. The Revenue Benchmark and the EBIT Benchmark for each District for
the 2001 fiscal year shall be as set forth on Schedule I attached to this Plan.
The Committee shall have the authority to amend Schedule I at any time to
increase or decrease the performance benchmarks, to add or remove Districts or
otherwise as the Committee, in its sole discretion, deems necessary or
advisable. For each fiscal year following the 2001 fiscal year, the Revenue
Benchmark for each District shall be calculated by adding that District's
Revenue Benchmark for the immediately preceding fiscal year to the amount of
revenue credited to such District during such fiscal year and dividing the sum
of those two numbers by two; provided, however, in no event shall the Revenue
Benchmark for a fiscal year ever be less than the Revenue Benchmark for the
immediately preceding fiscal year. For each fiscal year following the 2001
fiscal year, the EBIT Benchmark for each District shall be calculated by adding
that District's EBIT Benchmark for the immediately preceding fiscal year to the
amount of EBIT credited to such District during such fiscal year and dividing
the sum of those two numbers by two; provided, however, in no event shall the
EBIT Benchmark for a fiscal year ever be less than the EBIT Benchmark for the
immediately preceding fiscal year.

SECTION VI. GENERATION OF BONUS POOLS.

         As soon as practical following the end of each fiscal year, a Pool
shall be established for each District in an amount equal to $0.02 for each
$1.00 of revenue generated during such fiscal year by such District that is over
and above that District's Revenue Benchmark for such fiscal year, plus $0.22 for
each $1.00 of such District's EBIT for such fiscal year that is over and above
that District's EBIT Benchmark for such fiscal year. In addition, regardless of
whether or not a District meets its Revenue Benchmark or its EBIT Benchmark
during any fiscal year, (i) if a District has EBIT for any fiscal year that are
greater than fifteen percent (15%) of such District's revenues for such fiscal
year, then a contribution will be made to such District's Pool in an amount
equal to one-quarter of one percent (0.25%) of such District's revenues for such
fiscal year, and (ii) if a District has a Return on Assets during any fiscal
year that is greater than fifty percent (50%), then a contribution will be made
to such District's Pool in an amount equal to one quarter of one percent (0.25%)
of such District's revenues for such fiscal year. For the purposes of
calculating the revenue, EBIT, Return on Assets and Return on Sales of each
District, other than the Bridgewater, Bridgewater Construction and GeoSciences
Districts, fifty percent (50%) of the IGS Revenue and fifty percent (50%) of the
IGS Profit from any IGS Project performed in a District's geographic territory
(as determined by the Committee in its sole discretion) shall be added to the
financial results of such District upon the last to occur of (i) completion of
such IGS Project and (ii) recognition of the IGS Revenue and/or IGS Profit for
such IGS Project in the Company's financial results.

         Notwithstanding the foregoing, (i) the Committee shall have the option,
at its sole discretion, of eliminating part or all of the incentive compensation
awards which otherwise could be

                                       3
<PAGE>

made under this Plan in any given fiscal year in which the Company's EPS is
negative for such fiscal year; (ii) no incentive compensation awards shall be
made to a District's Participants in any given fiscal year if that District's
Return on Sales is less than eight percent (8%) for such fiscal year; and (iii)
the Committee shall have the option, at its sole discretion, of eliminating part
or all of any project with revenues over $5 million performed by a District
during any given fiscal year from the calculation of that District's revenues,
EBIT, Return on Sales or Return on Assets for such fiscal year and electing to
provide incentive compensation with respect to such projects, if any, separately
from this Plan on a project by project basis.

SECTION VII. DETERMINATION OF AMOUNT OF AWARD.

         The amount of incentive award to be granted from the Pool to all
General, District and Branch Managers shall be determined by the operating vice
president responsible for that District with the concurrence of the Company
President. The amount of the incentive award to be granted from the Pool to all
other Participants shall be determined by the General, District and/or Branch
Managers with the concurrence of the operating vice president responsible for
that District. The amount of the individual awards shall be discretionary, in
the sole judgment of those making the awards, based upon the individual's
performance for that fiscal year, provided, however, that in no event shall the
amount of any Participant's award exceed 100% of that Participant's annual
regular salary as of the first day of that fiscal year.

SECTION VIII. TYPE OF AWARD.

         The incentive compensation award will be paid in cash, restricted or
unrestricted common stock of the Company, or a combination of any of the
foregoing as determined by the Board of Directors of the Company or the
Compensation Committee thereof.

SECTION IX. TERMINATION OF EMPLOYMENT.

         In the event a Participant voluntarily terminates his or her employment
with the Company at any time prior to the close of the fiscal year, the
Participant will not be eligible for any award otherwise payable for the fiscal
year.

         In the event a Participant is involuntarily terminated (without cause)
prior to the close of the fiscal year, the Participant will be considered for
receipt of the award he or she would have otherwise received (as determined by
the Committee in its sole discretion) and, if awarded, prorated to reflect the
length of the Participant's service during the relevant fiscal year. The
Committee will take into consideration the circumstances of the termination in
determining the propriety and amount of the award. The Company's payment of
severance or post-employment salary support to a Participant will not be
considered part of the Participant's annual regular salary for purposes of the
Plan.

SECTION X. MISCELLANEOUS.

         There shall be deducted from each cash payment made under the Plan the
amount of any tax requested by any governmental authority to be withheld by the
Company with respect to such payment. A Participant receiving stock hereunder
shall have deducted by the Company from the award the amount of any taxes which
the Company is required by any governmental authority to withhold with respect
to such stock prior to calculation of the number of shares of stock to be
awarded.

         Nothing in the Plan shall be construed to give any person any benefit,
right or interest except as expressly provided herein, and nothing in the Plan
shall be construed as establishing any right of continued employment by the
Company.

         A Participant's rights and interests under the Plan may not be assigned
or transferred. In the case of a Participant's death prior to payment of a
Participant's award, payment in an amount equal to

                                       4
<PAGE>

what the Participant would have otherwise received had he or she been employed
on the last day of the fiscal year (as determined by the Committee in its sole
discretion), prorated to reflect the length of the Participant's service during
the relevant fiscal year, shall be made to the personal representatives of the
Participant's estate or such other person or persons as the Committee deems
appropriate.

         The Board of Directors of the Company, or the Compensation Committee
thereof, may discontinue the Plan, in whole or in part, at any time, or may,
from time to time, amend the Plan in any respect that such Board (or Committee)
may deem advisable. In the event the Plan is terminated, no further payments
will be made under the Plan.

SECTION XI. EFFECTIVE DATE.

         The Plan, as amended, shall be effective as of February 1, 2003.

            h.    Subject  to  existing  agreements  with Chesapeake Exploration
            Limited  Partnership,  Palace  Exploration  Company,  Castlerock
            Resources,  Inc.,  and Tularosa, Inc. dated effective March 28, 2002
            whereby  GHK's interest is reduced by a proportionate 15%, 14%, 0.5%
            and  0.5%  respectively.

            i.    GHK  reserves  and  excepts unto itself all rights in existing
            wellbores,  equipment,  facilities  and  pipelines  within  the AMI.
            Should  any  existing wellbore be reentered, recompleted or deepened
            ("subsequent  operation")  to  a formation that is to be assigned to
            Participant,  then  Participant shall have the option to participate
            in  the subsequent operation by paying its ownership share of GHK' s
            actual  cost  to  drill  the well to the point before the subsequent
            operation along with its ownership share of the cost to complete the
            subsequent  operation.

      4.2   The interest assigned shall be subject to its proportionate share of
      all  royalties,  overriding  royalties,  production  payments  and  other
      leasehold  burdens  created,  reserved, excepted or assigned in any of the
      instruments  referred  to  in  Article  4.1  above.

    V.      AREA  OF  MUTUAL  INTEREST
            --------------------------

      5.1   An  Area  of  Mutual  Interest  ("AMI")  identical  in  area  to the
      aforementioned  Contract  Area  is  hereby  established.

      5.2   The  AMI created pursuant to this paragraph shall be effective as of
      the  same date this Agreement is effective and shall continue for a period
      of  five  (5) years thereafter. The duration of the AMI can be extended or
      reduced  only  by  written  agreement  of  the  parties  hereto.

      5.3   Should Participant or anyone ion their behalf, or for their benefit,
      directly  or indirectly after the effective date of this Agreement acquire
      any Additionally Acquired Interests within the AMI, then Participant shall
      offer  GHK  the right to acquire its Ownership Share of the same by paying
      its  proportionate  share  of  the costs incurred in connection therewith.
      Participant  shall  give prompt written notice of all the particulars with
      respect  to  price,  terms  and  conditions relative to such leases and/or
      rights  with the AMI. GHK shall have ten (10) days (forty-eight [48] hours
      if  a  well  is  drilling  or  completing  within  one [1] mile of the AMI
      outline)  to  acquire its proportionate share of such offering by paying a
      like  share  of  the  actual  land costs attributable to such acquisition.
      Failure  or  refusal  to notify or pay Participant in the manner set forth
      above shall constitute an election by GHK not to acquire its proportionate
      share  of  said  interest.

      5.4   Participant  shall  offer  GHK  its Ownership Share of any leasehold
      interest,  unleased  mineral interest, force pooled interest, or any other
      interests  or  rights  whatsoever  ("Participant's  Interests"),  which
      Participant  currently  owns within the AMI. Participant's Interests shall
      be  offered  in  writing  to  GHK  within ten (10) days from execution and
      delivery  of  this  Agreement  and GHK will have ten (10) days to elect to
      acquire  its Ownership Share of Participant's Interests at actual cost and
      existing  net  revenue interest. Participant's Interests shall be assigned
      by  Participant  to  GHK  within  thirty (30) days of GHK's payment of its
      proportionate  share  of  land  costs,  subject  to  an overriding royalty
      interest  equal  to the difference between existing burdens and twenty two
      percent  (22.00%), it being the intent of Participant to deliver a seventy
      eight percent (78.00%) net revenue interest in the Participant's Interests
      to GHK. In the event Participant's Interest has existing burdens in excess
      of  twenty  two percent (22.00%), then such interest shall be delivered to
      GHK  at  existing  net  revenue  interest and Participant shall reserve no
      overriding  royalty  interest  as  to  such  interest.

    VI.     INITIAL  WELL  COMMITMENT
            -------------------------

      6.1   The  Parties  hereto agree to join in the drilling of the Mary #2-34
      well  ("Initial  Well") at a location in the Southwest ("SW/4") of Section
      34,  Township  3  North,  Range 20 East, Latimer County, Oklahoma. GHK has
      commenced  drilling  and is currently drilling the Initial Well at a depth
      of approximately 17,500'. GHK shall diligently pursue the drilling of said
      Initial  Well  to a total depth of 24,500' below the surface of the ground
      or a depth sufficient to adequately test the Arbuckle formation, whichever
      is the lesser depth. For the purpose of drilling said Initial Well, all of
      Section  34-3N-20E,  Latimer  County,  Oklahoma  shall  be  considered the
      appropriate  drilling  and spacing unit unless changed by 011K pursuant to
      State  and/or  Federal  rules  and  regulations  or  by  mutual agreement.

      6.2   Should  the  total  costs as reflected on the AFE attached hereto as
      Exhibit  "C" exceed one hundred and ten percent (110%), Participant agrees
      to  pay  its  proportionate  Ownership  Share,  as  determined pursuant to
      Articles  3.1  and 4.1 hereinabove, of all costs incurred in the drilling,
      testing,  equipping,  producing and operating the Initial Well that exceed
      110% of the AFE. GHK will invoice Participant for such costs incurred on a
      monthly  basis.

      6.3   If,  prior  to  reaching the authorized depth during the drilling of
      the  Initial  Well,  or  prior  to  completing  said  well, conditions are
      encountered, which would render further operations by a reasonably prudent
      Operator  impractical  or unreasonably dangerous and Operator is forced to
      abandon  the  well,  then,  within  sixty  (60)  days  after  cessation of
      operations  GHK  shall have the right to commence or cause to be commenced
      the  actual  drilling  of  a  "Substitute Well" for said Initial Well at a
      mutually  acceptable  (among  the  parties  of  the  Operating  Agreement)
      location  on the Contract Area described in the JOA, and then continue the
      drilling  thereof  in  the same manner and to at least the same authorized
      depth  as  provided for the Initial Well, and such Substitute Well when so
      drilled  shall  qualify  as  the  Initial Well. Assignor may drill as many
      Substitute  Wells  as  may  be  necessary  to  reach  the authorized depth
      provided  operations  for  each  Substitute Well shall be commenced within
      sixty (60) days of cessation of operations of the previous Substitute Well
      unless a shorter term is required by any of the Leases or Agreements. Each
      such  Substitute  Well  shall be considered under this Agreement to be the
      Initial  Well.

      6.4   By  execution  of  this Agreement, the parties hereto agree that all
      operations  conducted within the AMI shall be conducted in accordance with
      the  terms and provisions of the form Operating Agreement, attached hereto
      as  Exhibit  "B".  At  such  time  as  the  first well is proposed in each
      drilling  and  spacing  unit  within  the AMI, there shall be prepared and
      submitted  by  the  Operator  for  approval  by  Participant, an operating
      agreement  similar  in  form  as  Exhibit  "B"  attached  hereto.

    VII.    OPERATOR  OF  CONTRACT  AREA
            ----------------------------

      7.1   GHK  shall  be designated Operator of all operations in the AMI. and
      shall  conduct,  direct and have full control of all operations, including
      determination of appropriate drilling and spacing unit size, in the AMI as
      permitted  and  required  within the limits of this agreement, Participant
      agrees  to  support GHK as Operator at any hearing before any State and/or
      Federal  regulatory  body  in  which  GHK  is  seeking  operations.

    VIII.   SUBSEQUENT  WELLS
            -----------------

      8.1   Should  GHK  desire  to drill a well or wells ("Subsequent Well") in
      addition  to  the  Initial  Well on lands in the AMI, then with respect to
      each  additional  well  GHK  shall  give Participant written notice of the
      proposed  operation  specifying  the work to be performed, the approximate
      location,  proposed  depth, objective formation, and the estimated cost of
      the  operation  in  the form of an AFE. Participant shall have thirty (30)
      days  after  receipt of the

Exploration Agreement.doc               5
<PAGE>
     notice  within  which to notify, in writing, GHK whether Participant elects
     to  participate  in  the  cost  of  the  proposed  operation.  Failure  of
     Participant  to reply within the 30-day period shall constitute an election
     by  that  party  NOT  to
                      ---
      participate  in  the  cost  of  the proposed operation. Should Participant
      elect  to  participate,  they  shall pay and bear an undivided ten percent
      (10%) interest in the wellbore of the Subsequent Well by paying 1.33 times
      of  the  actual  costs associated with the drilling and completion of such
      well.  The  10% interest shall be proportionately reduced to the total GHK
      interest  in  the well. By way of clarification and example, if GHK owns a
      50%  interest  in  a Subsequent Well, Participant's participation interest
      will  be 50% times 10% (or 5%) and when multiplied by 1.33, will result in
      Participant  paying  6.65%  of the actual costs of drilling and completing
      said  well.  Participant's  interest  in  any well shall be limited to the
      wellbore  only  of  such  well.

      8.2   Notwithstanding  anything  to  the contrary contained in Exhibit "B"
      attached  hereto,  in  the  event  GHK proposes that Subsequent Well(s) be
      drilled  in  the  AMI,  Participant  will have thirty (30) days to make an
      election  to  participate  in  such  well or forever forfeit its rights to
      participate  in  that  well  or  any other well drilled in that particular
      spacing  unit.

    IX.     DELAY  RENTALS,  MINIMUM  ROYALTIES,  SHUT-IN  ROYALTIES
            --------------------------------------------------------

      9.1   If any delay rental, minimum royalty or shut-in royalty shall become
      due  on  any  oil  and  gas lease subject to this agreement while the same
      remains in force and effect and such oil and gas lease is not then subject
      to  an  effective JOA entered into pursuant to the terms and provisions of
      this  Agreement,  then the party hereto who originally acquired such lease
      shall  pay  such  delay rental, minimum royalty or shut-in royalty and the
      other  owner  of  such  lease, determined in accordance with the terms and
      provisions  of  this  Agreement,  shall reimburse the paying party for its
      respective  proportionate  part  calculated  pursuant  to  the  terms  and
      provisions  of  this  Agreement upon receipt of an invoice evidencing such
      payment.

    X.      RELATIONSHIP  OF  PARTIES
            -------------------------

      10.1  Nothing contained in this Agreement is intended to create, nor shall
      this  Agreement  be  construed  as creating, a partnership, joint venture,
      mining  partnership,  association  or other relationship whereby any party
      hereto  shall  ever  be held liable for the acts, debts, or obligations of
      the  other. The duties, obligations and liabilities of the parties to this
      Agreement  shall  be several and not joint, it being understood and agreed

      appeared  herein.

    XL.     RISK  OF  LOSS
            --------------

      11.1  GHK  and  Participant  understand  and  agree  that the drilling and
      exploration  for  hydrocarbons  is  a  highly  speculative  venture  and
      Participant  agrees  that GHK has made no warranties or representations as
      to the success or financial gain relative to the above captioned prospect.
      Participant,  by  acceptance  of  this  Agreement,  signifies  that it has

      hereto  with  respect  to  the AMI, and shall only be amended by a written
      instrument  executed  by  all  the  parties  hereto.

      12.5  Each  of  the parties to this Agreement represents it is not a party
      to  any  agreement  or  arrangement  which  conflicts  with  the terms and

      civil  disorder,  Acts  of  God,  unavoidable  accidents,  laws,  rules or
      regulations  of governmental bodies or agencies, delays in transportation,
      inability  to  obtain  necessary materials or equipment including drilling
      rigs,  in  the  open market, or any other cause, except financial, whether
