Tesco agrees that, in the absence of a subpoena or court order requiring its participation or support, Tesco shall not participate in or support any suit, claim, action, litigation, administrative proceeding, or proceeding of any nature against Weatherford that challenges the validity or enforceability of any of the Weatherford Patents, so long as the license to the Weatherford Patents under this Agreement remains in effect as to such patent.

5.1           Top Drive Equipment.  Each year, for a period of five (5) years after the Effective Date, Weatherford will purchase at least sixty-seven percent (67%) of its worldwide top drive requirements from Tesco, to the extent Tesco is able to meet the reasonable requirements of Weatherford and its customers as to quality, quantity, delivery and service.  During this five (5) year term, Steering Committee representatives of Tesco and Weatherford will meet (or at least communicate by email or phone) on a calendar quarterly basis to discuss Weatherford’s forecasted needs for top drives and Tesco’s manufacturing scheduling.





5.2           After-Market Sales and Services.  Each year, for a period of five (5) years after the Effective Date, Weatherford and Tesco will work together so that Tesco becomes the preferred provider of after-market sales and service (“AMSS”) to maintain all top drives in Weatherford’s top-drive fleet, regardless of manufacturer, using original equipment manufacturers’ (OEMs’) parts and supplies.  Tesco understands that in certain circumstances Weatherford may not be able to use Tesco to service a third party’s top drive due to prior service contract commitments and/or where such third party top drive is under the manufacturer’s warranty.  Weatherford and Tesco agree for Tesco to have an initial target of providing 50% of Weatherford’s AMSS, with the opportunity for Tesco to earn its way to providing 100% of Weatherford’s AMSS, based on Tesco’s ability to provide Weatherford’s reasonable requirements as to quality and timing.  During this five (5) year term, the Steering Committee shall serve as the sole and exclusive means by which the Parties will liaise and coordinate their respective activities under this Agreement.  In addition to ad hoc communication as and when needed to give effect to this Agreement, the Steering Committee shall meet (or at least communicate by email or phone) on a calendar quarterly basis to discuss Weatherford’s forecasted needs for servicing of its top drives within each country where Weatherford has its top drives and Tesco’s service capabilities in each such country.

5


5.3           Pricing.  The prices charged by Tesco for Paragraphs 5.1 and 5.2, above, shall be no greater than the prices charged by Tesco to any other customer of similar volume of purchases and/or services over the preceding twelve (12) months in the relevant geographic region.  The price paid for any top drive specially developed for or modified for Weatherford shall be negotiated at that time between the Parties.  Each sale consummated hereunder will be an independent transaction, and subject to Tesco’s standard terms and conditions of sale in effect at the date of the respective sale.





5.4           Agreement Not to Purchase.  As long as Paragraphs 5.1 and 5.2 remain in effect, Weatherford agrees not to purchase any casing running tools involved in the Houston Litigation, either directly or indirectly, from NOV.

As long as Paragraph 5.1 remains in effect, within thirty (30) days after the close of each calendar quarter, Weatherford will provide a summary report to Tesco of its world-wide top drive purchases and orders for the proceeding calendar quarter in sufficient detail for Tesco to assess Weatherford’s compliance with Paragraph 5.1.





5.6           Record Keeping and Audit.  To assess Weatherford’s compliance with Paragraphs 5.1 and 5.2, and to assess Tesco’s compliance with Paragraph 5.3, each Party agrees to keep records in sufficient detail to verify such compliance.  Each Party shall keep such records for no less than two (2) years after the end of the calendar quarter in question.  Each Party agrees to allow an independent third party auditor access during regular business days and working hours within fifteen (15) business days of receipt of a written notice of the request for such audit.  If a Party has a reasonable objection to the third party auditor chosen by the auditing Party, such Party may object within five (5) business days after receipt of the audit notice, and shall provide at least two (2) acceptable third party auditors.  The auditing Party may then proceed with the audit as scheduled using one of the acceptable third party auditors chosen by the other Party.  Any such audits and any disputes relating to compliance with Paragraphs 5.1, 5.2 and 5.3 may only take place within two (2) years after the end of the quarterly period being audited.  Each Party shall be responsible for all reasonable and customary audit costs associated with audits it requests; provided, however, that should a dispute arise hereunder based on audit findings, the Party prevailing in the dispute shall be entitled to reimbursement by the other Party of all such audit costs.

10.12           Waiver.  No waiver of any breach of any provision of this Agreement shall be construed as a waiver of or consent to any previous or subsequent breach of the same or any other provision.





10.13           Force Majeure.  The failure of a Party hereunder to perform any obligations, due to governmental action, law or regulation, or due to events, such as war, act of public enemy, strikes or other labor disputes, fire, flood, acts of God, or any similar cause beyond the reasonable control of such Party, is excused for as long as said cause continues to exist, it being understood and agreed that the mere obligation to pay money is not excusable under this provision.
