<PAGE>   8

          Effective in Mexico or for use in Mexico, which shall be restricted as
          provided in the first sentence of Section 2.4(f)(i), it shall have no

          Bradford Connection is to be sold or used and may rely solely on the

SECTION 2.5 LICENSEE SUB-LICENSES

         Licensee may grant sub-licenses to third parties with respect to its
rights hereunder subject to the following conditions:

         (a) Sub-Licenses

         Except for Affiliates of Licensee, no Sub-Licensee of Licensee or its
Affiliates shall be engaged or propose to be engaged in the business of the
Threading or Reconstruction of Connections for Products or Accessory Equipment
within the Grant Territory unless assurances reasonably satisfactory to Grant
are provided that such Sub-Licensee will not be able to utilize the Technology
and Patents in a manner that would adversely affect Grant; provided, however, no
Sub-Licensee shall have any rights under the Technology and Patents to Thread,
Reconstruct or sell Atlas Bradford Oil Field Connections in the Grant Territory
(other than Canada). Each Sub-Licensee (other than Affiliates of Licensee and
Sub-Licensees engaged solely in the Threading of Connections of




                                       8
<PAGE>   9



Accessory Equipment) shall be required to be approved by Grant in advance, which
approval shall not be unreasonably withheld.

         (b) Type of Sub-Licenses

         Each sub-license from Licensee shall be "non-exclusive" and
"non-assignable" (other than the sub-licenses that may be granted to Affiliates
of Licensee). No Sub-Licensee of Licensee shall have the right to sub-license
its rights other than to the customer for use.

         (c) Form of Sub-Licenses

         Each sub-license from Licensee shall be in a form consistent with the
terms of this Agreement and that shall be submitted to Grant for prior approval
(which approval shall be deemed granted if Grant does not object to its terms
within 15 days from its submission). Licensee shall not be required to submit to
Grant any sub-license agreement which is substantially similar to a standard
form approved by Grant; provided, however that an executed copy of each
sub-license from Licensee shall be provided to Grant promptly following the
execution thereof. Each sub-license shall provide that Grant is a third party
beneficiary.

         (d) Royalty Payments

         Any royalty payments that may be agreed with Sub-Licensees (including
payments for the procurement of Tooling and Gauges) shall be for the benefit of
Licensee.

         (e) Enforcement

         Licensee shall be fully responsible for any breach of the licenses
granted hereunder by a Sub-Licensee that is an Affiliate of Licensee. Licensee
shall otherwise not be a guarantor for any Sub-Licensee and therefore the breach
of the terms of the sub-license by a Sub-Licensee which is not an Affiliate of
Licensee or the failure to obtain from any such Sub-Licensee the performance of
obligations under the sub-license shall not entitle Grant to regard Licensee as
being in breach of its obligations hereunder nor to terminate this Agreement so
long as Licensee continues to exercise and enforce its rights under the
sub-license or terminates, in accordance with its terms, the relevant
sub-license. Grant shall not be required to seek remedies against a Sub-Licensee
that is an Affiliate of Licensee and may act directly against Licensee for any
breach of any such Affiliate. The failure of a Sub-Licensee that is an Affiliate
of Licensee to comply with the terms of this Agreement shall entitle Grant to
regard Licensee as being in breach of its obligations hereunder and to terminate
this Agreement as provided in Section 10.4.

         (f) Duration

         The longest duration of any sub-license from Licensee shall be one day
shorter than the effective term of this Agreement according to whether it
expires or is previously terminated; provided that if this Agreement is
terminated prior to its initial term any Sub-Licensee which is not an Affiliate
of Licensee may upon termination apply directly to Grant for the adoption of the
sub-


                                       9
<PAGE>   10



license directly whereupon Grant shall, if the Sub-Licensee is not an
Affiliate of Licensee nor is in default and there are no other legal impediments
to such adoption, adopt the same.

               (i) Licensee shall assume the license with P.T. Citra Tubindo
          ("CITRA TUBINDO") attached hereto as Schedule "D" (the ACITRA
          LICENSE"). Citra Tubindo may not grant sub-licensees of its rights,
          except to H-Tech or an Affiliate of Citra Tubindo. Licensee may not
          terminate the Citra License without the prior written consent of Grant
          (other than as a result of an uncured material breach thereof), which
          may be withheld by Grant in its sole discretion, and shall allow the
          Citra License to be extended from time to time as requested by Grant.
          In addition, Grant shall have the right to consent to the right of
          Citra Tubindo to Thread and sell Atlas Bradford Oil Field Connections
          under the Citra License in other territories; provided, however, Grant
          agrees that it will not consent to the right of Citra Tubindo to
          Thread or Reconstruct Atlas Bradford Oil Field Connections in
          Argentina, Columbia, Italy, Mexico and Venezuela.

               (ii) Licensee agrees that Citra Grant Prideco Limited, an
          affiliate of Grant (ACITRA GRANT"), has been appointed a distributor
          of Products and Accessory Equipment with Atlas Bradford Oil Field
          Connections that have been Threaded or Reconstructed by Citra Tubindo
          and its Affiliates pursuant to the Citra License in the territories
          described therein. Licensee further agrees that the Citra License
          shall continue in effect and not be required to be terminated and that
          Citra Grant shall be entitled to continue to distribute Products and
          Accessory Equipment that have been Threaded or Reconstructed by Citra
          Tubindo and its sub-licensees.

         (h) Sub-License Grant Prideco Limited

         Licensee undertakes to grant to Grant Prideco Limited a non-exclusive
sub-license to Thread, Reconstruct and sell Accessory Equipment and to
Reconstruct Products with Atlas Bradford Connections within the North Sea
theater on customary terms and conditions to be agreed upon in good faith
between Grant Prideco Limited and Licensee recognizing Grant Prideco Limited's
current use of the technology. The license shall be subject to a royalty fee of
4% of the price paid to Grant Prideco Limited for the Atlas Bradford Connections
sold or provided by Grant Prideco Limited subsequent to the Effective Date and
during the term of such sub-license. In addition, Licensee agrees that it and
its Affiliates will offer to Grant Prideco Limited the opportunity to Thread any
full length Products with Atlas Bradford Connections within the North Sea
theatre as long as Grant Prideco Limited is able to provide such Threads at a
price to Licensee and its Affiliates equal to or less than the price at which a
Sub-Licensee of Licensee could provide such services. Licensee may not terminate
Grant Prideco Limited's Sub-License without the prior written consent of Grant
(other than as a result of an uncured material breach thereof), which may be
withheld by Grant in its sole discretion.

         (i) Licensees to Grant and its Affiliates

         Licensee agrees to grant to Grant or any of its Affiliates a
non-exclusive license under the Technology and Patents to Thread, Reconstruct
and sell Atlas Bradford Oil Field Connections on Accessory Equipment in the
Exclusive Territory to the extent Grant or such Affiliate enters into a


                                       10
<PAGE>   11


sub-license agreement with Licensee and pays all required royalties thereunder
to Licensee; provided, Licensee shall not be obligated to license Grant or its
Affiliates if Licensee determines in its reasonable good faith that the granting
of such license would not be economically or commercially advantageous to
Licensee.

SECTION 2.6 PATENT INFRINGEMENT

         (a) Grant covenants not to bring suit against Licensee or any of its
Sub-Licensees for infringement of any Patent arising from Licensee's and its
Sub-Licensee's performance in strict accord with this Agreement.

         (b) Any claims for any infringement of Technology, Patents or
Trademarks shall belong solely to Grant and any recoveries with respect thereto
shall belong to Grant except to the extent such recoveries solely and
specifically relate to an infringement of the Technology or Patents for Threaded
or Reconstructed Atlas Bradford Oil Field Connections on full length Products in
the Licensee Territories for which an exclusive license has been granted to
Licensee in such territories, in which case such recoveries shall belong to
Licensee to the extent of its interest. Licensee shall be primarily responsible
for the defense of any infringement claims with respect to Technology, Patents
or Trademarks in the Licensee Territories for which an exclusive license has
been granted to Licensee to the extent the claim relates to the Exclusive
Territories; provided, however, in the event Licensee does not diligently
enforce its rights under Technology, Patents and Trademarks in the Exclusive
Territory, then, upon written notice to Licensee, Grant may enforce those
rights. Grant shall also have the exclusive right to defend any claims for
infringement in Grant Territory and a right to participate at its expense in any
actions in the Exclusive Territory. Licensee, however, shall have no right to
bring any action with respect to any infringement for the Technology, Patents or
Trademarks without the prior written consent of Grant, which shall not be
unreasonably withheld. Grant shall be entitled to participate in such actions.
Licensee shall not be entitled to take any action that would adversely affect
the right or validity of any of Technology or Trademarks without the prior
consent of Grant, which may be withheld in its sole and absolute discretion.

         (c) In the event Grant enters into any settlement with respect to any
infringement claim with respect to Technology, Patents or Trademarks, Grant
agrees that it will not release or extinguish any rights of Licensee to the
Technology, Patents or Trademarks for use in the Exclusive Territory.

SECTION 2.7 USE OF PRODUCTS BY END USERS

         Use of Products and Accessory Equipment by end users (drilling
contractors, oil companies and other similar users) is not restricted by this
Agreement and such end users may use and transfer such Products and Accessory
Equipment freely throughout the world without restriction hereunder. Grant or
Licensee, as the case may be, however, may be subject to commissions on such use
and transfer under Section 2.3(g) or to any other applicable remedy for
transactions made in violation of the provisions of this Agreement.

SECTION 2.8 COMMISSIONS

         (a) In consideration of the undertakings made by Licensee hereunder,
Grant agrees to pay to Licensee the following commissions:

                  (i) A commission equal to ***% of any royalties received by
         Grant and its Affiliates from a party that is not Affiliated with Grant
         from the Threading by such unAffiliated party (other than from Licensee
         and its Affiliates and its Sub- Licensees) of any Atlas Bradford
         Connections on (a) Products or Accessory Equipment of carbon steel of
         9% or less Cr that are sold or delivered for use in the Exclusive
         Territory and (b) Products and Accessory Equipment of all grades with
         Atlas Bradford Oil Field Connections that are sold or delivered for use
         in Mexico, in both cases by such unAffiliated Party (other than
         Licensee and its Affiliates and its Sub-Licensees) after the Effective
         Date and during the term of this Agreement.

                  (ii) A commission equal to ***% of any payments made to Grant
         or its Affiliates by an unAffiliated customer or distributor for any
         Atlas Bradford Oil Field Connections on (a) Products and Accessory
         Equipment of carbon steel of 9% or less Cr or on Products or Accessory
         Equipment of all grades in the case of Mexico (whether or not the
         Product that is Threaded is owned by the Customer or Grant or its
         Affiliates prior to the sale) that are Threaded by Grant or any of its
         Affiliates after the Effective Date and during the term of this
         Agreement and that are ultimately sold or used in the Exclusive
         Territory; provided, however, if Grant or Licensee cannot or does not
         demonstrate the amount of the payment made to Grant or its Affiliates
         for such Atlas Bradford Oil Field Connections and Licensee is able to
         demonstrate that such Atlas Bradford Oil Field Connections were
         Threaded by Grant or one or more of its Affiliates after the Effective
         Date and during the term of this Agreement, then the commission
         payable will be based on Grant's or its Affiliates' then existing
         price list for such Atlas Bradford Oil Field Connections.

                  (iii) The foregoing commissions shall only be applicable to
         Products sold after the Effective Date and only for those Products and
         Accessory Equipment that are sold or shipped during the term of this
         Agreement for consumption in the Exclusive Territory. Grant agrees to
         provide to Licensee a report within 60 days following the end of each
         calendar quarter setting forth a list of all sales or shipments of
         Products and Accessory Equipment of carbon steel of 9% or less Cr (and
         in the case of Mexico Products and Accessory Equipment of all grades)
         containing Atlas Bradford Oil Field Connections made into the Exclusive
         Territory by Grant's and its Affiliates' distributors, agents and
         customers during the quarter. Such report shall be based on information
         provided to Grant and Grant Affiliates and Grant licensees from such
         distributors, agents and customers, the Grant licensees and any other
         data known to Grant and Grant Affiliates. Licensee shall be entitled to
         object to such report and if it is able to demonstrate that sales or
         shipments of Products of carbon steel of 9% or less Cr containing Atlas
         Bradford Oil Field Connections were made after the Effective Date in
         the Exclusive Territory by Grant, the Grant Affiliates or Grant
         Licensees (other than Licensee, its Sub-Licensees, Citra Tubindo, OCTL
         or Citra Grant), Grant will be required to pay a commission with
         respect to such sales.


                                       12

                    (iv) Grant shall pay any required commission contemporaneous
               with the delivery of the report under Section 2.8(a)(iii) and
               will be entitled to a credit against the commission payable
               pursuant to this Section 2.8(a) for (x) all actual documented
               expenses incurred by Grant in providing Licensee support for
               Products and Accessory Equipment sold by it, Grant Affiliates and
               their distributors, agents and customers in the Exclusive
               Territory and (y) any commissions payable to Grant under Section
               2.8(b).

                    (v) The commissions payable by Grant under this Section
               2.8(a) shall not be in lieu of any other rights that Licensee may
               have against Grant or any distributor or customer of Grant for
               any sales of Atlas Bradford Oil Field Connections into the Home
               Territories or for use in the Home Territories in violation of
               this Agreement; provided, however, that a breach by a distributor
               or customer of Grant of the resell or use restrictions required
               under this Agreement shall not be considered a breach by Grant
               under this Agreement and Licensee shall be entitled to take
               action against a distributor or customer that acts in violation
               of the resell and use restrictions contained herein; provided
               further, however, that if a distributor or customer of Grant
               violates the resell or use restrictions required under this
               Agreement, Grant shall be obligated to pay to Licensee all
               profits realized by Grant from such distributor or customer on
               the sale of such Product and Atlas Bradford Oil Field Connection
               that was resold by the distributor or customer in violation of
               such restrictions.

         (b)   Although Licensee and its Affiliates shall be restricted from
making any sales of Atlas Bradford Oil Field Connections in the Grant Territory
(excluding Canada) and shall be required to restrict sales by customers (other
than customers who are end users that are purchasing for their own use and not
for resale), in recognition of Grant's retained rights to the Technology and
Patents, Licensee agrees to pay to Grant the following commissions:

                    (i) A commission equal to ***% of any royalties received by
               Licensee and its Affiliates from a party that is not Affiliated
               with Licensee from the Threading by such unAffiliated party
               (other than from Grant and its Affiliates and its sub- licensees)
               of any Atlas Bradford Connections on Products or Accessory
               Equipment that are sold or delivered for use in the Grant
               Territory (excluding Canada) by such unAffiliated party (other
               than Grant and its Affiliates and its sub-licensees) after the
               Effective Date and during the term of this Agreement.

                    (ii) A commission equal to ***% of any payments made to
               Licensee or its Affiliates by an unAffiliated customer or
               distributor for any Atlas Bradford Oil Field Connections on
               Products (whether or not the Product that is Threaded is owned by
               the Customer or Licensee or its Affiliates prior to the sale)
               that are Threaded by Licensee or any of its Affiliates after the
               Effective Date and during the term of this Agreement and that are
               ultimately sold or used in the Grant Territory (excluding
               Canada); provided, however, if Grant or Licensee cannot or does
               not demonstrate the amount of the payment made to Licensee or its
               Affiliates for such Atlas Bradford Oil Field Connections and
               Grant is able to demonstrate that such Atlas Bradford Oil Field
               Connections were Threaded by Licensee or one or more of its
               Affiliates after the Effective Date and during the term of this
               Agreement, then the commission payable will be based on
               Licensee's or its Affiliates' then existing price list for such
               Atlas Bradford Oil Field Connections.

               then the commission payable will be based on Licensee's or its
               Affiliates' then existing price list for such Atlas Bradford Oil
               Field Connections.

                    (iii) The foregoing commission shall only be applicable to

               Products that are sold or shipped during the term of this
               Agreement for consumption in the Grant Territory (excluding

               (excluding Canada) by Licensee's and its Affiliates'
               distributors, agents and customers during the quarter. Such
               report shall be based on information provided to Licensee and
               Licensee Affiliates and Licensee's sub-licensees from such
               distributors, agents and customers, the Licensee's sub-licensees
               and any other data known to Licensee and Licensee's sub-licensee
               Affiliates. Grant shall be entitled to object to such report and
               if it is able to demonstrate that sales or shipments of Products
               of Accessory Equipment containing Atlas Bradford Oil Field
               Connections were made after the Effective Date in the Grant
               Territory (other than Canada) by Licensee, Licensee Affiliates

                    (iv) Licensee shall pay any required commission
               contemporaneous with the delivery of the report under Section
               2.8(b)(iii) and will be entitled to a credit against the
               commission payable pursuant to this Section 2.8(b) for any

                    (v) The commissions payable by Licensee under this Section
               2.8(a) shall not be in lieu of any other rights that Grant may
               have against Licensee or any distributor or customer of Licensee
               for any sales of Atlas Bradford Oil Field Connections into the
               Grant Territory (other than Canada) or for use in the Grant
               Territory (other than Canada) in violation of this Agreement;
               provided, however, that a breach by a distributor orcustomer of
               Licensee of the resell or use restrictions required under this
               Agreement shall not be considered a breach by Licensee under this
               Agreement and Grant shall be entitled to take action against a
               distributor or customer that acts in violation of the resell and
               use restrictions contained herein; provided further, however,
               that if a distributor or customer of Licensee or its
               Sub-Licensees or its Affiliates violates the resell or use
               restrictions required under this Agreement, Licensee shall be
               obligated to pay to Grant all profits realized by Licensee or its
               Affiliates from such distributor or customer on the sale of such
               Product and Atlas Bradford Oil Field Connection that was resold

for the patents, technology and trademarks for the New Grant Connections shall
be deemed to be fully paid and subject to the terms hereof, including
exclusivity, territory and use and be included within the definition of
Technology, Patents, and Trademarks. Notwithstanding the foregoing, Grant or any
of its Affiliates may seek and obtain a license of patents and technology
relating to Connections from an unAffiliated third party without an obligation
to license the same under this Agreement. The foregoing shall also not apply to
XL Technology.

         (c) Contemporaneous herewith, EVI, as the controlling Affiliate of

SECTION 12.1      US EXPORT CONTROL REGULATIONS

         Grant's obligations under this Agreement are subject to the export
control regulations of the government of the United States of America, the
European Union and other applicable governments. Compliance of the parties with
such export control Regulations is a condition of this Agreement. Nothing
contained in this Agreement shall be deemed to have granted any rights contrary
to such laws or Regulations.

SECTION 12.2      REGISTRATION OF AGREEMENT

         Promptly upon execution and delivery of this Agreement, Licensee shall
register, if required, this Agreement in the appropriate departments, agencies,

necessary approvals as may be required by law in the Territories.

SECTION 12.3      COOPERATION TO OBTAIN APPROVALS AND LICENSES

         Grant and Licensee shall cooperate in obtaining any approvals or
licenses which may be required in connection with the implementation of any
portion of this Agreement.

                            ARTICLE 13. FORCE MAJEURE

         If performance of this Agreement or of any obligation under this
Agreement, except payment of moneys due and maintaining information and
documents in confidence, is prevented, restricted or interfered with by acts of
government, war, rebellion, riot, labor unrest, unavailability of materials,
Acts of God, or any other force, act or condition beyond the reasonable control
of the parties ("Force Majeure"), the party affected by Force Majeure shall be
excused from such performance to the extent of such prevention, restriction or
interference, provided that the party so affected promptly notifies the other
party of the Force Majeure condition, uses its best efforts to avoid or remove
the Force Majeure condition, and continues performance under this Agreement with
utmost dispatch when such Force Majeure condition is removed. In the event a
Force Majeure condition results in suspension of performance under this
Agreement for a continuous period of one year or more, the party not affected by
the Force Majeure condition may terminate this agreement by giving the affected
party written notice of termination.

                     ARTICLE 14. GOVERNING LAW; CONSTRUCTION

SECTION 14.1 GOVERNING LAW

         This Agreement shall be deemed made pursuant to, and shall be governed
by the laws of the State of New York, except the conflict of laws provisions
thereof.

SECTION 14.2 SEVERABILITY

         Both parties expressly agree that it is not the intention of either
party to violate any public policy, statue or common law; and if any
provision(s) of this Agreement shall be held to be invalid, illegal or
unenforceable, in whole or in part, in any jurisdiction within which the
Agreement is to be performed, or if any appropriate government agency or
authority shall require the parties to delete any provision of this Agreement,
such invalidity, illegality, enforceability or deletion shall not impair or
affect the remaining provisions of this Agreement, so long as the material
purposes of this Agreement can be determined and effectuated. The parties shall
endeavor in good faith negotiations to replace the invalid, illegal,
unenforceable or deleted provisions by valid provisions, the effect of which
comes as close as legally possible to the intention of the parties upon entering
into this Agreement.

SECTION 14.3 NON WAIVER

         The failure of one party hereto to enforce at any time any of the
provisions of this Agreement, or exercise any rights or any elections herein
provided, shall in no way be considered to be a waiver of such provisions,
rights or elections or in any way to affect the validity of this Agreement. The
exercise by said party of any rights or any elections under the terms of this
Agreement shall not preclude or prejudice said party from exercising the same or
any other rights or elections it may have under this Agreement.

                             ARTICLE 15. ASSIGNMENT

         This Agreement shall be binding upon and inure to the benefit of the
parties, their successors and assigns, provided that the assignor shall remain
liable to the other party for the obligations arising under this Agreement.
Notwithstanding the foregoing Licensee may not assign its rights, directly or
indirectly, by merger, sale of assets, conversion or a change in control of
Licensee, to any person or entity that directly or through an Affiliate Threads,
Reconstructs or sells Connections on Products and Accessory Equipment in the
Grant Territory. Further any such assignment shall, at the election of Grant, be
void or result in an immediate termination of the licenses granted hereunder to

                       ARTICLE 16. SETTLEMENT OF DISPUTES

         If, during the term of this Agreement or after its termination,
disputes, controversies, claims or differences arising out or relating to this
Agreement (including any questions as to the existence, validity, termination,
discharge, breach or enforceability of this Agreement and of this arbitration
clause), arise between Grant and Licensee, the parties shall take every
reasonable effort to negotiate an amicable settlement. In the event the parties
are unable to reach a settlement within thirty (30) days after notice by any of
the parties is given to the other party acknowledging the existence of a dispute
to be solved in accordance with the provisions of this section, then either
party may request arbitration pursuant to the then current rules of the
International Chamber of Commerce domiciled in Paris for arbitration in
accordance with the rules of said organization. Each party shall appoint one
arbitrator of its choice, and the two appointed arbitrators shall appoint a
third arbitrator. A decision agreed to by at least two of the arbitrators shall
be the decision of the Arbitration proceeding. In the event either party fails
to appoint an arbitrator or in the event no agreement is reached between the two
arbitrators as to the appointment of the third arbitrator in accordance with the
foregoing provisions, such arbitrator or arbitrators shall be appointed, upon
application of the interested party, by the Court of Arbitration of the
International Chamber of Commerce. Unless the parties agree otherwise, the site
of the arbitration shall be New York, New York. Arbitration proceedings shall be
conducted in the English language. Any decision or award of the arbitrators
shall be based solely on the provisions of this Agreement, provided, however,
that to the extent that the subject matter for the decision or award is not
provided for in such provisions, the decision or award shall be based upon the
controlling law of this Agreement, excluding the conflicts of laws provisions
thereof. The arbitrators shall not be requested nor shall they have the power to
render any decision or award except in accordance with the preceding sentence.
The award rendered in any arbitration commenced hereunder shall be final and
conclusive and judgment thereon may be entered in any court having jurisdiction
for its enforcement. Neither party shall appeal to any court from the decision
of the arbitration panel. In addition, except for injunctive relief in aid of
arbitration, neither party shall have any right to commence or maintain any suit
or legal proceeding concerning a dispute hereunder until the dispute has been
determined in accordance with the arbitration procedure provided for herein and
then only for enforcement of the award rendered in such arbitration. Pending
settlement of any dispute, the parties shall abide by their obligations under
this Agreement without prejudice to a final adjustment in accordance with an
award rendered in an arbitration settling such dispute. A party may be entitled
to receive injunctive relief from a court of competent jurisdiction in aid of
arbitration.
