                              AMENDED AND RESTATED
                            INDEMNIFICATION AGREEMENT

     This Amended and Restated Indemnification Agreement (this "Agreement") is
entered into and effective as of July __, 2004 between Synetics Solutions Inc.,
an Oregon corporation (the "Company"), Yaskawa Electric Corporation ("YEC") and
Yaskawa Electric America, Inc. (together with YEC, the "Shareholders").

     The Company intends to prepare and file with the Securities and Exchange
Commission a Registration Statement on Form S-1 (the "Registration Statement")
under the Securities Act of 1933, as amended (the "1933 Act"), relating to
6,900,000 shares of common stock of the Company to be offered by the Company,
and in connection therewith, the Company intend to enter into an Underwriting
Agreement with Adams, Harkness & Hill, Inc., Wells Fargo Securities, LLC and
Nomura Securities International, Inc. that will be filed as an exhibit to the
Registration Statement (hereinafter referred to as the "Underwriting
Agreement").

     Now, therefore, in consideration of the mutual covenants and conditions
contained herein, the Company and the Shareholders agree as follows:

     1. The Company shall indemnify and hold harmless each Shareholder, the
officers, directors and shareholders of each Shareholder, and each person, if
any, who controls such Shareholder within the meaning of the 1933 Act, against
any losses, claims, damages or liabilities, joint or several, to which they may
become subject under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus, the Registration Statement or the
prospectus, or any amendment or supplement thereto, or any new registration
statement or prospectus, or in any marketing materials or information provided
to investors by, or with the approval of, the Company in connection with the
marketing of the offering of the shares of common stock of the Company,
including any roadshow or investor presentations made to investors by the
Company (whether in person or electronically), or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading
(collectively, a "Violation"); and the Company will pay to each person intended
to be indemnified pursuant to this section 1(a), as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action, provided, however,
that the agreement contained in this section 1(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected by either Shareholder without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable in any such case for any such loss, claim, damage, liability, or action
to the extent that it arises out of or is based upon a Violation that occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Shareholder, officer,
director or controlling person.

     2. Promptly after receipt by an indemnified party under this Agreement of
notice of the commencement of any action (including any governmental action),
such indemnified party
<PAGE>
will, if a claim in respect thereof is to be made against any indemnifying party
under this Agreement, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties that may
be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with reasonable fees and expenses to be paid by the
indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Agreement, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Agreement.

     3. To the extent the indemnification provided for in this Agreement is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to herein,
the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party, on the one hand, and of the
indemnified party, on the other hand, in connection with the Violation(s) that
resulted in such loss, claim, damage or liability, as well as any other relevant
equitable considerations; provided, however, that in no event shall any
contribution made by a Shareholder under this section 4 exceed the net proceeds
from the offering received by such Shareholder. The relative fault of the
indemnifying party and of the indemnified party shall be determined by a court
of law by reference to, among other things, whether the untrue or allegedly
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     4. (A) This Agreement constitutes the entire agreement between the Company
and the Shareholders and supersedes all prior agreements and understandings,
oral and written, among the parties hereto with respect to the subject matter
hereof.

        (B) This Agreement shall not be assignable by any of the parties hereto
without the prior written consent of each of the Company and each Shareholder.

        (C) This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective successors and assigns, subject to the
restrictions on assignment contained in section 4(b). Nothing express or implied
in this Agreement is intended or shall be construed to confer upon or give to a
person, firm or corporation other than the parties hereto any rights or remedies
under or by reason of this Agreement or any transaction contemplated hereby.

                                       2
<PAGE>
        (D) Subject to applicable law, this Agreement may be amended, modified
and supplemented at any time by written agreement executed and delivered by the
duly authorized officers of each of the Company and each Shareholder.

        (E) Any failure of the Company, on the one hand, or any of the
Shareholders, on the other hand, to comply with any obligation, covenant,
agreement or condition herein may be waived by the Shareholders, on the one
hand, or the Company, on the other hand, only by a written instrument signed by
the party or parties granting such waiver, but such waiver or failure to insist
upon strict compliance with such obligation, covenant, agreement or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure.

        (F) For the convenience of the parties hereto, this Agreement may be
executed in any number of counterparts, each such counterpart being deemed to be
an original instrument, and all such counterparts shall together constitute the
same agreement.

        (G) This Agreement shall be governed by and construed in accordance with
the laws of the state of Oregon, exclusive of choice of law rules.

        (H) Any term or provision of this Agreement which is held by a court of
competent jurisdiction to be invalid, illegal or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability without rendering invalid,
illegal or unenforceable the remaining terms and provisions of this Agreement or
affecting the validity, legality or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.

        (I) If a dispute arises out of, or relates to, this Agreement, or the
breach thereof, and if the dispute cannot be settled through negotiation, the
parties agree first to attempt in good faith to settle the dispute by mediation
administered by the American Arbitration Association under its Commercial
Mediation Rules before resorting to litigation or any other type of dispute
resolution procedure.

3.    REGISTRATION PROCEDURES. The Company is required by the provisions of this
Agreement to use its Best Efforts to effect the registration of the Registrable
Shares under the Securities Act, and will take the actions described below in
this Section 3.

      3.1.  Registration Statement. The Company will prepare and file with the
Commission a Shelf Registration Statement with respect to the Registrable Shares
and use its Best Efforts to cause such Shelf Registration Statement to become
effective as promptly as practicable, but in any event within 60 days after the
filing of such Shelf Registration Statement.

      3.2.  Amendments and Supplements. The Company will prepare and file with
the Commission such amendments (including post-effective amendments) and
supplements to such Shelf Registration Statement and the prospectus used in
connection therewith as may be necessary to keep such Shelf Registration
Statement effective during the Effectiveness Period, and during such period the
Company will comply with the provisions of the Securities Act with respect to
the disposition of all Registrable Shares and other securities, if any, covered
by such Shelf Registration Statement until the end of the Effectiveness Period.

      3.3.  Cooperation. The Company will use its Best Efforts to (i) cooperate
with the Selling Holder in the disposition of the Registrable Shares covered by
the Shelf Registration Statement, (ii) enter into and perform customary
agreements related to the registration and disposition of the Registrable Shares
(including underwriting agreements in customary form) and (iii) cause key
executives of the Company and its subsidiaries to participate under the
direction of the managing underwriter in one or more "road shows" scheduled by
such managing underwriter in such locations and of such duration as in the
judgment of such managing underwriter are appropriate for underwritten
offerings; provided, that any such "road shows" shall not exceed five (5)
business days, shall not include more than one "road show" per year and (with
the exception of any "road show" conducted in connection with the Simultaneous
Public Offering) shall be at the expense of the Selling Holder.

      3.4.  Copies of Prospectus. The Company will furnish to each Selling
Holder (i) promptly after such Shelf Registration Statement is filed with the

and all exhibits, (ii) upon the effectiveness of such Shelf Registration
Statement, such number of copies of the prospectus included in such Shelf
Registration Statement, including all amendments and supplements thereto, and
(iii) such other documents, in each case, as the Selling Holder may reasonably
request in order to facilitate the Public Offering of the Registrable Shares
owned by the Selling Holder.

      3.5.  Blue Sky Qualification. Prior to the Public Offering of any
Registrable Shares, the Company will use its Best Efforts to register or qualify
the Registrable Shares covered by the

                                        4
<PAGE>

Shelf Registration Statement under the securities or "blue sky" laws of such
states or jurisdictions in the United States as the Selling Holder may
reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the Selling Holder to consummate the public
sale or other disposition in such jurisdictions of the Registrable Shares
covered by the Shelf Registration Statement, including preparing and filing in
those jurisdictions such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Effectiveness Period; provided,
however, that the Company will not be obligated to file any general consent to
service of process or to qualify as a foreign corporation in any jurisdiction in
which it is not so qualified or to subject itself to taxation in respect of
doing business in any jurisdiction in which it would not otherwise be so
subject. The Company shall promptly notify each Selling Holder of the receipt by
the Company of any notification with respect to the suspension of the
registration or qualification of any Registrable Shares for sale under the
securities or "blue sky" laws of any jurisdiction in the United States or its
receipt of notice of the initiation or threat of any proceeding for such
purpose.

      3.6.  Opinion of Counsel; Comfort Letter. In the case of any underwritten
offering, the Company will use its Best Efforts to obtain all legal opinions,
auditors' consents and comfort letters and experts' cooperation as may be
required, including furnishing to each Selling Holder and each of the
underwriters of such Registrable Shares a signed counterpart, addressed or
confirmed to such Selling Holder and each of the underwriters, of (a) an opinion
of counsel for the Company (in form, scope and substance reasonably satisfactory
to the managing underwriter and the Selling Holder) and (b) a "cold comfort"
letter signed by the independent public accountants who have certified the
Company's financial statements included or incorporated by reference in such
Shelf Registration Statement, covering substantially the same matters as are
customarily covered in opinions of issuer's counsel and in accountants' letters
delivered to underwriters in underwritten public offerings of securities.

      3.7.  Listing and Transfer Agent. The Company will cause all Registrable
Shares covered by the Shelf Registration Statement to be listed on each
securities exchange or automated quotation system on which the Common Stock is
then listed. The Company will provide and cause to be maintained a transfer
agent and registrar for all Registrable Shares covered by the Shelf Registration
Statement not later than the effective date of such Shelf Registration
Statement.

      3.8.  General Compliance with Federal Securities Laws; Section 11(a)
Earning Statement. The Company will use its Best Efforts to comply with the
Securities Act, the Exchange Act and any other applicable rules and regulations
of the Commission, and make available to its securities holders, as soon as
reasonably practicable, an earning statement covering the period of at least 12
months after the effective date of such Shelf Registration Statement, which
earnings statement shall be in a form complying with and satisfying Section
11(a) of the Securities Act and any applicable regulations thereunder, including
the provisions of Rule 158.

      3.9.  Notice of Prospectus Defects. The Company will immediately notify
the Selling Holder, and (if requested by the Selling Holder) confirm such notice
in writing, of the happening of any event, as a result of which the prospectus
included or to be included in the Shelf

                                       5
<PAGE>

Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing (provided that such notice shall not contain any
material, non-public information). The Company will promptly revise such
prospectus as may be necessary so that such prospectus shall not include an
untrue statement of a material fact or omit to state such a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing. The Company will
promptly deliver copies of such revised prospectus to the Selling Holder.
Following receipt of the revised prospectus, the Selling Holder will be free to
resume making offers of the Registrable Shares. The Company will extend the
period during which the Shelf Registration Statement must be kept effective
pursuant to this Agreement by the number of days during the period from and
including the date of giving such notice to and including the date when the
Selling Holder shall have received copies of the revised prospectus.

      3.10. H & P Lock-Up. H & P, Holder or Selling Holder will refrain, without
the consent of the managing underwriter, from the date of execution of this
Agreement to 180 days after the completion of the Simultaneous Public Offering,
from directly or indirectly selling, offering to sell, granting any option for
the sale of, pledging, or otherwise disposing of any Common Stock, whether in
accordance with the terms of Rule 144, Rule 144A or otherwise (except as part of
such Simultaneous Public Offering); provided, however, that should there be no
Simultaneous Public Offering, should there be an underwriter's cutback (as
described in Section 4.2 hereof) such that H & P, Holder or Selling Holder shall
not include any Registrable Shares in the Simultaneous Public Offering or should
H & P, Holder or Selling Holder notify the Company in writing that it does not
wish to proceed with the sale of Registrable Shares in the Simultaneous Public
Offering and irrevocably waives its right to participate in the Simultaneous
Public Offering, H & P, Holder or Selling Holder agrees to not effect any Public
Offering or distribution (including sales pursuant to Rule 144, Rule 144A or
otherwise) of Common Stock during the seven days prior to and the 90-day period
beginning on the effective date of any underwritten registered Public Offering
of equity securities of the Company or securities convertible or exchangeable
into or exercisable for equity securities of the Company, unless the
underwriters managing the registered Public Offering otherwise agree, and H & P,
Holder or Selling Holder will deliver an undertaking to the managing
underwriters (if requested) consistent with the covenants in this Section 3.10.

      3.11. Delay of Registration and Suspension of Offering. If at any time
after the Shelf Registration Statement has become effective, the Company is
engaged in any plan, proposal or agreement with respect to any financing,
acquisition, recapitalization, reorganization or other material transaction or
development the public disclosure of which would be detrimental to the Company,
then the Company may direct that use of the prospectus contained in the Shelf
Registration Statement be suspended, as applicable, for a period of up to 30
days. The Company will notify all Holders requesting the registration or all
Selling Holders, as the case may be, of the delay or suspension. Each Selling
Holder will immediately discontinue any sales of Registrable Shares pursuant to
such Registration Statement until such Selling Holder has received copies of a
supplemented or amended prospectus or until such Selling Holder is advised in
writing by the Company that the then-current prospectus may be used and has
received copies of any additional or supplemental filings that are incorporated
or deemed incorporated by reference in such prospectus. The Company will extend
the period during which the Shelf

                                        6
<PAGE>

Registration Statement must be kept effective pursuant to this Agreement by the
number of days during the period from and including the date of giving such
notice to and including the date when the Selling Holder shall have received
copies of the revised prospectus or notice from the Company that the
then-current prospectus may be used.

      3.12. Participation by Selling Security Holders. In connection with the
preparation and filing of the Shelf Registration Statement with respect to the
Registrable Shares, and before filing any such Shelf Registration Statement or
any other document in connection therewith, the Company must give the
participating Holders and their underwriters, if any, and their respective
counsel and accountants, the opportunity to participate in the preparation of
such Shelf Registration Statement, each prospectus included therein or filed
with the Commission, each amendment thereof or supplement thereto and any
related underwriting agreement or other document to be filed, and give each of
the aforementioned Persons such access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such Holders, underwriters, counsel or
accountants, to conduct a reasonable investigation within the meaning of the
Securities Act.

      3.13. Requests by Selling Holder. If requested by a Selling Holder, the
Company shall (i) as soon as practicable incorporate in a prospectus supplement
or post-effective amendment such information as a Selling Holder reasonably
requests to be included therein relating to the sale and distribution of
Registrable Shares, including, without limitation, information with respect to
the number of Registrable Shares being offered or sold, the purchase price being
paid therefor and any other terms of the offering of the Registrable Shares to
be sold in such other offering provided that such information is required to be
included in the Shelf Registration Statement by the Securities Act; (ii) as soon
as practicable make all required filings of such prospectus supplement or
post-effective amendment after being notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment; and (iii) as soon as
practicable, supplement or make amendments to any Registration Statement if
reasonably requested by a Selling Holder of such Registrable Shares.

      3.14. Stop Orders. The Company shall use its Best Efforts to prevent the
issuance of any stop order or other suspension of effectiveness of the Shelf
Registration Statement, or the suspension of the qualification of any of the
Registrable Shares for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify each Selling Holder of the issuance
of such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

      3.15. Certificates. The Company shall reasonably cooperate with the
Selling Holder and, to the extent applicable, facilitate the timely preparation
and delivery of certificates representing the Registrable Shares to be offered
pursuant to the Shelf Registration Statement and enable such certificates to be
in such denominations or amounts, as the case may be, as the Selling Holder may
reasonably request and registered in such names as the Selling Holder may
request.

                                       7
<PAGE>

      3.16. Notice of Effectiveness. Within two business days after the Shelf
Registration Statement, or any amendment thereto, that includes the Registrable
Shares is declared effective by the Commission, the Company shall deliver, and
shall cause legal counsel for the Company to deliver, to the transfer agent for
such Registrable Shares (with copies to the Selling Holder) written confirmation
that such Shelf Registration Statement has been declared effective by the
Commission.

      3.17. Governmental Approvals. The Company shall use its Best Efforts to
cause the Registrable Shares covered by the Shelf Registration Statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to consummate the disposition of such Registrable Shares.

      3.18. Requests for Information. In connection with the Shelf Registration
Statement, H & P, Holder and Selling Holder shall furnish to the Company in
writing such information as the Company reasonably requests in writing for use
in connection with the Shelf Registration Statement or prospectus.

4.    CERTAIN OTHER PROVISIONS.

      4.1.  Additional Procedures. Selling Holder will take all such actions and
execute all such documents and instruments that are reasonably requested in
writing by the Company to effect the sale of their shares in any Public
Offering, including, without limitation, being parties to the underwriting
agreement entered into by the Company and any other Selling Holder in connection
therewith. In addition, each Selling Holder will furnish to the Company such
information regarding such Selling Holder and the distribution proposed by such
Selling Holder as the Company may reasonably request in writing and as will be
required in connection with any registration, qualification or compliance
referred to in Section 3.

      4.2.  Underwriter's Cutback. Notwithstanding any other provision of this
Agreement, if the managing underwriter determines that the inclusion of all
shares requested to be offered in the Simultaneous Public Offering would
materially and adversely affect the offering, the managing underwriter may limit
the number of Registrable Shares to be included in such offering. In such case,
the number of shares that are entitled to be included in the Simultaneous Public
Offering will be reduced to a number deemed satisfactory by the managing
underwriter so as to include, first, up to 1,000,000 shares of Common Stock
offered by the Company, second, up to 1,000,000 Registrable Shares, if any, and,
thereafter, shares of Common Stock offered by the Company, if any.

      4.3.  Up-size and Over-Allotment. In the case of an up-size in the number
of shares of Common Stock to be included in the Simultaneous Public Offering,
such that the number of shares of Common Stock sold in the Simultaneous Public
Offering exceeds 2,000,000 shares, all such shares of Common Stock in excess of
2,000,000 shares will be offered by the Company, with no increase in the
Registrable Shares to be included in the Simultaneous Public Offering. In the
case of the exercise of an over-allotment by the underwriters in the
Simultaneous Public Offering, the number of shares of Common Stock that are
entitled to be included in the Simultaneous Public Offering will be increased
such that, first, the Company shall be entitled to offer an aggregate of up to
1,000,000 shares of Common Stock in the Simultaneous Public

                                        8
<PAGE>

Offering, second, the Holders shall be entitled to offer an aggregate of up to
1,000,000 Registrable Shares, if any, in the Simultaneous Public Offering and,
thereafter, the Company shall be entitled to offer all shares of Common Stock in
excess of 2,000,000 shares, if any, with no further increase in the number of
Registrable Shares entitled to be included in the Simultaneous Public Offering.

      4.4.  Registration Expenses. The Company hereby agrees to pay all expenses
incurred for its sole benefit pursuant to this Agreement. H & P, Holder and
Selling Holder agree to pay all expenses incurred for their sole benefit
pursuant to this Agreement. With respect to the Simultaneous Public Offering,
any expenses which are for the joint benefit of the Company and H & P, Holder or
Selling Holder shall be allocated based upon the number of shares of Common
Stock sold by each such Person in the Simultaneous Public Offering. In any
event, H & P, Holder and Selling Holder shall pay filing fees allocable to the
Registrable Shares, fees and expenses, if any, of counsel or other advisers to H
& P, Holder or Selling Holder or underwriting discounts, brokerage fees and
commissions allocable to the Registrable Shares.

      4.5.  Termination of Status as Registrable Shares. Registrable Shares will
cease to be Registrable Shares and cease to have the rights accorded to such
shares under this Agreement upon the earliest to occur of the following events:
(x) such shares shall have been sold pursuant to an effective Registration
Statement under the Securities Act, (y) such shares shall have been sold
pursuant to a transaction under Rule 144, Rule 144A or (except for sales to
Helmerich & Payne, Inc. or any of its wholly-owned subsidiaries) otherwise or
(z) the termination of the Effectiveness Period.

      4.6.  Limitations on Subsequent Registration Rights. The Company will not,
without the prior written consent of Holders of at least a majority of the
Registrable Shares, enter into any agreements with any holder or prospective
holder of Company securities that grant such holder or prospective holder rights
to include securities of the Company in any Registration Statement, unless such
rights are subordinated to the rights granted to the Holders under this
Agreement.

5.    INDEMNIFICATION.

      5.1.  Company Indemnification. To the fullest extent permitted by law, the
Company will indemnify and hold harmless each Selling Holder, its partners,
directors, officers, employees and agents and each other Person, if any, who
controls such Selling Holder (within the meaning of the Securities Act or the
Exchange Act) and each such controlling Person's partners, directors, officers,
employees and agents (each such Person being a "Covered Person") from and
against any and all losses, claims, damages, liabilities, costs (including,
without limitation, reasonable attorneys' fees) and expenses (collectively,
"Losses" and individually a "Loss"), joint or several, to which such Covered
Person may become subject, insofar as such Losses (or actions in respect
thereof) arise out of or are based upon (a) any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary or final prospectus contained in the Registration Statement, or
any amendment or supplement to such Registration Statement or (b) the omission
or alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; and the Company will
reimburse such Covered

                                       9
<PAGE>

Person for any legal or any other expenses reasonably incurred by such Covered
Person in connection with investigating or defending any such Loss or action;
provided, however, that the Company will not be liable to any Covered Person in
any such case (x) to the extent that any such Loss arises out of or is based
upon any untrue statement or omission made in such Registration Statement or
prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in writing, by or on
behalf of such Covered Person or the Selling Holder specifically for use in the
preparation thereof or (y) in the case of a sale directly by a Selling Holder
(including a sale of such Registrable Shares through any underwriter retained by
such Selling Holder engaging in a distribution solely on behalf of such Selling
Holder), such untrue statement or omission was contained in a preliminary
prospectus and corrected in a final or amended prospectus, and such Selling
Holder failed to deliver a copy of the final or amended prospectus at or prior
to the confirmation of the sale of the Registrable Shares to the person
asserting any such Loss, in any case in which such delivery is required by the
Securities Act.

      5.2.  Seller Indemnification. In the event of any registration of any of
the Registrable Shares under the Securities Act pursuant to this Agreement, then
to the fullest extent permitted by law, each Selling Holder will indemnify and
hold harmless the Company, each of its directors, officers, employees and agents
and each Person (other than such Selling Holder), if any, who controls the
Company within the meaning of the Securities Act or the Exchange Act, against
any Losses to which the Company, such directors, officers, employees and agents
or controlling Person may become subject, insofar as such Losses (or actions in
respect thereof) arise out of or are based upon (a) any untrue statement of a
material fact contained in any Registration Statement under which such
Registrable Shares were registered under the Securities Act, any preliminary or
final prospectus contained in the Registration Statement, or any amendment or
supplement to the Registration Statement or (b) the omission to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in each case only if the statement or omission was made in
reliance upon and in conformity with information furnished in writing to the
Company by or on behalf of such Selling Holder, specifically for use in
connection with the preparation of such Registration Statement, prospectus,
amendment or supplement.

      5.3.  Notice of Claims, etc. Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a
claim of the type referred to in the foregoing provisions of this Section 5,
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party, give written notice to each such indemnifying party of
the commencement of such action; provided, however, that the failure or delay of
any indemnified party to give such notice will not relieve such indemnifying
party of its obligations under this Section 5, except to the extent that such
indemnifying party is materially prejudiced by such failure or delay. In case
any such action is brought against an indemnified party, each indemnifying party
will be entitled to participate in and to assume the defense thereof, jointly
with any other indemnifying party similarly notified, to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and
(subject to the following sentence) after written notice from an indemnifying
party to such indemnified party of its election so to assume the defense
thereof, such indemnifying party will not be liable to such indemnified party
for any legal or other expenses subsequently incurred by the latter in
connection with the defense thereof. The indemnified party may participate in
such defense at such party's expense;

                                       10
<PAGE>

provided, however, that the indemnifying party will pay such expense if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflict of
interests between the indemnified party and any other party represented by such
counsel in such proceeding; provided, further, that in no event will the
indemnifying party be required to pay the expenses of more than one law firm as
counsel for all indemnified parties pursuant to this sentence. If, within 30
days after receipt of the notice, such indemnifying party has not elected to
assume the defense of the action, such indemnifying party will be responsible
for any and all legal or other expenses reasonably incurred by such indemnified
party in connection with the defense of the action, suit, investigation, inquiry
or proceeding. An indemnifying party may, in the defense of any such claim or
litigation, consent to the entry of a judgment or enter into a settlement
without the consent of the indemnified party only if (i) such judgment or
settlement contains a general release of the indemnified party in respect of
such claims or litigation and (ii) such release is in form and substance
reasonably satisfactory to the indemnified party.

      5.4.  Contribution. If the indemnification provided for in Sections 5.1 or
5.2 hereof is unavailable to a party that would have been an indemnified party
under any such Section in respect of any Losses (or actions or proceedings in
respect thereof) referred to therein, then each party that would have been an
indemnifying party thereunder will, in lieu of indemnifying such indemnified
party, contribute to the amount paid or payable by such indemnified party as a
result of such Losses (or actions or proceedings in respect thereof) in such
proportion as is appropriate to reflect the relative fault of such indemnifying
party on the one hand and such indemnified party on the other in connection with
the statements or omissions which resulted in such Losses (or actions or
proceedings in respect thereof). The relative fault will be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by such indemnifying party or such indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties agree
that it would not be just and equitable if contribution pursuant to this Section
5.4 were determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in the
preceding sentence. The amount paid or payable by a contributing party as a
result of the losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) referred to in this Section 5.4 will include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

6.    MISCELLANEOUS.

      6.1.  Reports under the Exchange Act. With a view to making available to
the Holders the benefits of Rule 144 and any other rule or regulation of the
Commission that may at any time permit such Holder to sell securities of the
Company to the public without registration and with a view to making it possible
for Holders to register the Registrable Shares pursuant to a Registration
Statement on Form S-3, the Company agrees from the date hereof to use its best
efforts to:

      other documents required of the Company under the Securities Act and the
      Exchange Act, so long as the Company remains subject to such requirements
      and the filing of such reports and other documents are required for the
      applicable provisions of Rule 144 to apply;

            (c) file with the Commission in a timely manner all reports and
      other documents required of the Company under the Securities Act and the
      Exchange Act and take such other actions as will permit Holders to use
      Form S-3 for the resale of their Registrable Shares; and

            (d) furnish to any Holder forthwith upon request (i) a written
      statement by the Company as to its compliance with the reporting
      requirements of Rule 144, the Securities Act and the Exchange Act, or as
      to its qualification as a registrant whose securities may be resold
      pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of
      the most recent annual or quarterly report of the Company and such other
      reports and documents so filed by the Company and (iii) such other
      information as may be reasonably requested in availing any Holder of any
      rule or regulation of the Commission that permits the selling of any such
      securities without registration or pursuant to such form.

      6.2.  Transfer of Rights. The rights set forth herein are non-transferable
except to Helmerich & Payne, Inc. or any of its wholly-owned subsidiaries, and
except as set forth in Article 6 hereof, this Agreement is made solely for the
benefit of H & P and such permitted transferees.

      6.3.  Governing Law; Waiver of Jury Trial. This Agreement, the rights of

controversies, hearings, charges, complaints or proceedings arising in whole or
in part under or in connection herewith, will be governed by and construed in
accordance with the domestic substantive laws of the State of Texas, without
giving effect to any choice or conflict of law provision or rule that would
cause the application of the laws of any other jurisdiction. EXCLUSIVE
JURISDICTION SHALL LIE IN HOUSTON, HARRIS COUNTY, TEXAS. The parties hereto
hereby waive any right to a jury trial in connection with any litigation
pursuant to this Agreement.

      6.4.  Entire Agreement; Amendment and Waiver. This Agreement, together
with any documents, instruments and certificates explicitly referred to herein,
constitutes the entire agreement among the parties hereto with respect to the
subject matter hereof and supersedes any and all prior discussions,
negotiations, proposals, undertakings, understandings and agreements, whether
written or oral, with respect thereto. Any term of this Agreement may be amended
or terminated and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) with the written consent of the Company and a Majority in
Interest of the Registrable Shares. Any such amendment, termination or waiver
will be binding on all Holders.
