          B.  Owner and Charterer shall enter into the Drilling Make-Ready
              Contract under which Owner shall contract Charterer to prepare the
              Vessel and her appurtenances for operations in the area of

         Prior to redelivery, the Vessel shall be surveyed, including video
         taped, by a recognized commercial marine surveyor jointly selected by
         Owner and Charterer, to determine the condition thereof. The cost of
         such survey shall be considered as an Operating expense as defined
         under Article 3 and be charged to the Owner. Such survey may be
         commenced while the Vessel is under tow. A copy of each report and
         video tape will be kept by Owner and Charterer.

         pursuant to this Charter to (x) third-parties and (y) Owner.

3.6      Increase in Charterer's Personnel

         A.   Under the terms of any Contract between Client/s and Charterer,
              Client may, at any time, with Charterer's approval, require
              Charterer to increase the number of Charterer's Personnel and the
              day rates. In no such event shall Charterer increase Charterer's
              personnel complement without receiving at least equal dayrate
              compensation from Client. In the event of such increases in
              personnel and costs, Charterer's Personnel Costs as defined in
              Schedule B shall be adjusted accordingly with such costs being
              passed on to Owner so long as such adjustments do not reduce the
              amount payable hereunder to Owner.

         B.   Upon the occurrence and during the continuation of any material
              event, circumstance or condition which is required to be remedied
              pursuant to any applicable Contract, Charterer may increase the
              number of Charterer's personnel complement to the extent
              reasonably necessary to effect such remedy; provided, that
              Charterer shall immediately provide Company with a detailed
              written notice describing such event, circumstance or condition,
              the proposed remedy (including timing and costs) and any other
              relevant information. To the extent reasonably practicable,
              Contractor shall coordinate and cooperate with Company to effect
              such remedy using proposals and procedures most economically
              beneficial to Company. 

3.7      Variation of Rates

         Since certain expenses related to the operation of the Vessel are
         passed through to the Owner at cost, except for Personnel Costs which
         are provided for in Schedule B, and certain insurance costs which are
         provided for in Article 4, expenses subtracted from the Dayrate under
         this Charter shall be varied as follows:

         A.   if Personnel Costs provided for in the Schedule B increase after 1
              February 1996, including all payroll burden and benefits paid by
              Charterer for its employees due to a corporate wage increase by
              Charterer, then the rates provided for in Schedule B shall
              increase a like amount no sooner than 1 February 1996 subject to
              approval by Owner, which approval shall not be withheld
              unreasonably.

         B.   if Client or Owner requires Charterer to increase the number of
              Charterer's Personnel, then the rates provided for in Schedule B
              shall, subject to 3.6, increase in relation thereto, including the
              costs of including labor burden and benefits.



                                       7
<PAGE>   8

         C.   if upon periodic review, which reviews shall occur at least
              quarterly, by Owner and Charterer, the burdens and costs reflected
              in Schedule B for Jones Act liability insurance, travel, safety,
              training, raises, bonuses, and relocation expenses are, in
              reasonable, good faith, mutually agreed to be more or less than
              the actual costs, then appropriate adjustments shall be made to
              the burdens and actuals in Schedule B as mutually agreed, in
              reasonable, good faith, by Owner and Charterer.

         D.   if at any time the management/shorebased personnel shown in
              Schedule B are not committing, directly or indirectly, all or
              substantially all of their business time to the Vessel, invoiced
              personnel costs related thereto from Charterer to Owner pursuant
              to this Charter shall be reduced accordingly to reflect work time
              not chargeable to the Vessel. It being the intention of the
              parties hereto that the Personnel Costs related to such
              management/shorebased personnel are in exchange for such personnel
              committing all or substantially all of their business time to the
              Vessel.


3.8      Payments to Owner shall be paid into the following bank account or to
         such other bank account as Owner may designate from time to time with
         thirty (30) days prior notice:

         jurisdiction (i.e. in Texas, such term is currently interpreted as
         meaning, among other things, conduct that is so shocking to common
         sensibility that it would support belief that the act or omission
         complained of was a result of conscious indifference to the right or
         welfare of the person affected by it. 53 Tex. Jr.3d, Negligence ?
         55fn.).

         Charterer at least annually.

         out of Charterer's failure to pay its debts when due or any liability
         or claim incurred or made against Charterer or for which Charterer
         accepts responsibility under this Charter to attach to the Vessel.

         the right to terminate this Charter (without any payment to the other
         except for amounts already payable through the termination date), in
         its sole discretion, by giving the other party at least 60 days prior
         written notice if at the time such notice is delivered there is no
         Contract then in effect requiring use of the Vessel.

         hereunder, Charterer shall be entitled to request Owner to repair or
         otherwise remedy such condition. If Owner has not commenced any such
         necessary repair or remedy procedures within sixty (60) days of receipt

         shall take effect immediately and no payments or other action by
         Charterer shall be due to Owner after that date except for payment of
         Charterhire already earned. In the case of termination other than under
         Article 11.2(ii) above, Charterer shall as soon as reasonably possible

         constitute the entire agreement and supersede all prior (oral or

         negotiations and all other communications or understandings between the
         parties hereto with respect to the subject matter hereof.

         in writing and signed by all of the parties hereto.

20.3     This Charter may be executed in multiple counterparts, each of which,

         masculine, feminine or neuter gender, shall include all other genders;
         the singular shall include the plural, and vice versa. Articles,
         sections and other titles or headings are for convenience only, and
         neither limit nor amplify the provisions of the Charter itself, and all
         references herein to articles, sections or subdivisions thereof shall
         refer to the corresponding article, section or subdivision thereof of
         this Charter unless specific reference is made to such articles,
         sections or subdivisions of another document or instrument.

         related to this Charter, and are hereby made a part of this Charter for
         all purposes.

         things necessary, proper or advisable under applicable laws and
         regulations to consummate and make effective the transactions
         contemplated by this Charter. In case, at any time after the execution

                                       18
<PAGE>   19

20.8     Any term or provision of this Charter that is invalid or unenforceable
         in any jurisdiction shall be ineffective as to such jurisdiction, to
         the extent of such invalidity or unenforceability, without rendering
         invalid or unenforceable the remaining terms and provisions of this
         Charter or affecting the validity or enforceability of any terms and
         provisions of this Charter in any other jurisdiction. If any provision
         of this Charter is so broad as to be unenforceable, each provision
         shall be interpreted to be only so broad as is enforceable. A
         bankruptcy or similar trustee must accept or, to the extent permitted
         by law, reject this Charter in its entirety.

         the parties hereto and their respective heirs, successors, assigns and

20.10    Neither action taken (including, without limitation, any investigation
         by or on behalf of any party) nor inaction pursuant to this Charter,
         shall be deemed to constitute a waiver of compliance with any
         representation, warranty, covenant or agreement contained herein by the
         party not committing such action or inaction. A waiver by any party
         hereto of a particular right, including, without limitation, breach of
         any provision of this Charter, shall not operate or be construed as a
         subsequent waiver of that same right or a waiver of any other right.

20.11    The rights, obligations and remedies created by this Charter are
         cumulative and in addition to any other rights, obligations or remedies
         otherwise available at law or in equity. Nothing herein shall be
         considered an election of remedies. Without being subject to the
         limitations required by common law, any party may enforce this Charter
         by an injunction or specific performance. In addition, any successful
         party is entitled to costs related to enforcing this Charter,
         including, without limitation, attorneys' fees, court costs and
         settlement and arbitration expenses.

20.12    Except as expressly provided in this Charter, nothing contained in this
         Charter shall be construed to confer any right, benefit or interest
         upon any person or entity other than the parties hereto.

         payment obligations contained herein.

20.14    Subject to the terms and conditions of this Charter, the parties hereto
         agree and acknowledge that Charterer is independent from and of Owner's
         control, and Charterer hereby agrees to act pursuant to the provisions
         of this Charter. Charterer is and agrees to maintain such independent
         status and relationship. Any provisions of this Charter that may appear
         to give Owner a measure of control over the details of the Charterer's
         operations shall be deemed to mean that Charterer shall follow the
         general desires of Owner but Charterer shall have authoritative control
         as to the details of performing the such operations. Neither Charterer
         nor any Charterer Representative shall be deemed to be the agents,
         representatives or employees of Owner. Nothing herein is intended to,
         or shall, create a partnership, joint venture, agency or other
         relationship creating fiduciary or quasi fiduciary duties or similar
         duties and obligations or otherwise subject the parties hereto joint
         and



                                       19

         several or vicarious liability or to impose any duty, obligation or
         liability that would arise therefrom with respect to either or both of
         the parties hereto.

         restructuring of this Charter and the First Amended and Restated
         Charter Agreement, dated as of even date herewith, between Owner and
         Charterer relating to the Bill Shoemaker, with the intent of arriving
         at a mutually agreeable Master Agreement, relating to the Vessel and
         the Bill Shoemaker, within six months of delivery of the Bill Shoemaker
         under a drilling contract.
