5.2 Warranties not Affected by Completion

The Warranties shall not in any respect be extinguished or affected by Completion.

5.3 Reliance

The Sellers acknowledge that the Buyer is entering into this Agreement in reliance upon representations in the terms of the Warranties made by the Warrantors with the intention of inducing the Buyer to enter into this Agreement and that, accordingly, the Buyer has been induced by those representations to enter into this Agreement.

5.4 No Recourse Against Employees

The Warrantors undertake to the Buyer that, in the event any claim is made against any of them arising out of or in relation to this Agreement or any of the Agreed Form Documents, they shall irrevocably and unconditionally waive any claim they may have against either Group Company or against any director, officer, employee or professional adviser of either Group Company on which, or on whom, they may have relied before agreeing to any terms of this Agreement or the Agreed Form Documents, or authorising any statement in the Disclosure Letter. However, this shall not preclude any Warrantor from claiming against any other Warrantor under any right of contribution or indemnity to which he may be entitled.

5.5 Buyer’s Knowledge

5.5.1 Subject to Clause 5.5.2 and 5.6.2, none of the Warranties, nor any provision in the Tax Deed, shall be, or shall be deemed to be, qualified, modified or discharged, nor shall a claim by the Buyer against the Warrantors under this Clause 5, be prevented or limited, by reason of any investigation or inquiry made by, or on behalf of the Buyer and no information relating to the Group of which the Buyer has knowledge (whether actual, constructive or imputed), (other than in the case of the Warranties (but, for the avoidance of doubt, not the Tax Deed) only by reason of its being disclosed in the Disclosure Letter in accordance with this Agreement) shall prejudice any claim which the Buyer (or either Group Company) shall be entitled to bring or shall operate to reduce any amount recoverable by the Buyer under this Agreement.

5.5.2 Having read the Disclosure Letter and reviewed the Data Room, the Buyer represents and warrants to each Seller that the Buyer is not aware of any matter that is likely to give rise to a claim for breach of the Warranties.

5.6 Knowledge, Information and Belief and Disclosure

5.6.1 Any reference in a Warranty to “so far as the Warrantors are aware” or a similar expression, means the actual knowledge of any Warrantor having made due and reasonable enquiries of the Sellers.

13

5.6.2 Save for those Warranties set out in paragraphs 2.1.1, 2.1.2, 3.1 and 3.2 of Part 4A of the Schedule, the Warranties are qualified by reference to those matters disclosed in the Disclosure Letter and the Data Room (but not otherwise) provided always that, in each case:

(a) each such matter shall be fully, fairly and accurately disclosed therein with sufficient details to identify the nature and scope of the relevant matter;

(b) it shall be sufficiently evident that, from the express wording of the relevant matter or the relevant document in the Data Room, it constitutes such a disclosure of facts inconsistent with the Warranties; and

(c) it shall not require independent or additional knowledge or information in order to understand the nature and scope of the relevant matter.

5.7 Separate and Independent Warranty

Each of the Warranties shall be construed as a separate and independent warranty and representation and (except where this Agreement provides otherwise) shall not be limited or restricted in its scope by reference to, or inference from, any other term of another Warranty or any term of this Agreement.

5.8 Calculation of Damages

5.8.1 Without prejudice to any other remedy available to the Buyer and without reference or regard to the general rule of law relating to claims for damages for breach of warranty, in the event that any of the Warranties is breached or is untrue or misleading, the relevant Warrantors who give that Warranty covenant, at the election of the Buyer, to pay to the Buyer within ten (10) Business Days following written demand for the same to such Warrantors, but subject always to the limitations of liability set out in and the other provisions of Part 5 of the Schedule either:

(a) a cash amount equal to the resulting diminution as at the date of this Agreement in the value of the Shares; or

(b) a cash amount equal to the aggregate of:

(i) the diminution or shortfall in value of any of the Group’s assets or contracts (including one warranted to exist but which does not in fact exist), which would not have occurred if the Warranties had not been breached or been untrue or misleading; and

(ii) the amount of any liability or increase in actual liability (and not contingent liability, unless and until such contingent liability becomes an actual liability), which either Group Company would not have incurred if the Warranties had not been breached or been untrue or misleading; and

(iii) the amount by which the profits in the period prior to the Completion Date of either Group Company are less or its losses greater than would have been the case if the Warranties had not been breached or been untrue or misleading; and

(iv) any reasonable costs and expenses incurred directly or indirectly as a result of, or in connection with any shortfall or diminution in value of any asset or contract or any liability or increased liability (as the case may be) referred to in paragraphs (i) or (ii) and the Warrantors shall not claim that any such costs and expenses incurred by the Buyer are unreasonable by reason of the Buyer’s choice of professional advisors.

14

5.8.2 Any payment made under Clause 5.8.1 shall:

(a) provide for an amount equal to any reasonable costs and expenses incurred in investigating, resisting, prosecuting or negotiating any Claim (provided such Claim shall not be settled or result in an award that in either case provides for no liability on any Seller) which gives rise to a liability on the part of the Warrantors (or any of them) under this Clause 5.8 and the Warrantors shall not claim that any such costs and expenses incurred by the Buyer are unreasonable by reason of the Buyer’s choice of professional advisors; and

(b) (in each case) have regard to the fact (as is the case) that the Buyer has entered into this Agreement with the intention that the business of the Group shall or may be continued as a going concern utilising all the assets and subject only to the liabilities to which, in accordance with the terms of this Agreement, the Group would on Completion be entitled and bound on the basis that all the Warranties were duly performed and fulfilled.

5.9 Costs

5.9.1 The relevant Warrantors shall indemnify, and keep indemnified, on demand, the Buyer against all costs and expenses suffered or incurred by the Buyer whether before or after the commencement of, and arising directly or indirectly out of, or as a result of:

(a) the settlement of any Claim by the Buyer against the Warrantors that any Warranty is untrue, or inaccurate, or that any Warranty or other term of this Agreement has been breached unless such settlement provides that the relevant Warrantors have no liability in respect of such Claim;

(b) any legal proceedings taken by the Buyer claiming that any Warranty is untrue, or inaccurate or misleading, or that any Warranty or other term of this Agreement has been breached, in which judgment is given for the Buyer; or

(c) the enforcement of any such settlement or judgment.

5.9.2 The Buyer shall indemnify, and keep indemnified, on demand, the Sellers against all costs and expenses suffered or incurred by the Warrantors in respect of a Claim made by the Buyer if:

(a) the terms of the settlement of such Claim by the Buyer and the Warrantors; or

(b) the terms of the award of the arbitral tribunal in respect of such Claim provides that none of the Warrantors has any liability in respect of such Claim.

5.10 Limitations

Following Completion the sole remedy of the Buyer in respect of any Claim shall be an action for damages, interdict, specific implement or other form of equitable relief (other than rescission). Save in the event of fraud by a Party no right of rescission shall be available to the other Party by reason of any fact, matter or circumstance giving rise to a Claim.

6.4 Separate and Independent Warranty

Each of the Buyer’s Warranties shall be construed as a separate and independent warranty and representation and (except where this Agreement provides otherwise), shall not be limited or restricted in its scope by reference to, or inference from any other term of another Buyer’s Warranty or any term of this Agreement.

16

8 RESTRICTIONS ON THE SELLERS

8.1 Restrictions on the Sellers

Each of the Sellers covenants with the Buyer and each Group Company that, save with the prior written consent of the Buyer, he shall not:

any business which directly competes with any part of the business carried on by either Group Company at the Completion Date or within twelve (12) Months prior to the Completion Date. Nothing in this Clause 8.1(a) shall prevent an Option Holder from being engaged as an employee or consultant of an energy services related business other than in respect of the provision by such Option Holder of artificial lift services and equipment. For the purposes of this Clause 8.1(a), “artificial lift services” shall mean any services (including mechanical devices for artificial lift) which add energy by any means of artificial lift (including mechanical, hydraulic or gas) to the hydrocarbon column (including liquids and gas) in a wellbore with the objective of initiating, improving or maintaining production from the well; or

(b) at any time during the period of three (3) years following the Completion Date:

(iii) engage in business with; or

(iv) work on any account or business of,

any person who is at the Completion Date, or who has been at any time during the period of twelve (12) Months immediately preceding that date, a client of either Group Company for the purposes of providing that client with services which are the same as, or similar to any services which he was involved in providing to that client at any time in the twelve (12) Months preceding the Completion Date; or

(c) at any time during the period of three (3) years following the Completion Date, canvass, solicit or otherwise seek the custom of any person who is at the Completion Date, or who has been at any time during the period of twelve (12) Months immediately preceding that date, a client of either Group Company for the purposes of providing that client with services which are the same as, or similar to any services which he was involved in providing to that client at any time in the twelve (12) Months preceding the Completion Date; or

(d) at any time during a period of three (3) years following the Completion Date, solicit or entice away from either Group Company any supplier to either Group Company who had supplied services to either Group Company at any time during the twelve (12) Months immediately preceding the Completion Date, if that solicitation or enticement causes or would cause such supplier to cease supplying, or materially reduce its supply of, those services to either Group Company; or

(e) without an intention to solicit or entice away, interfere with or seek to interfere with contractual or other trade relations between either Group Company and any of its clients; or

17

(f) at any time during the period of three (3) years following the Completion Date:

(i) offer employment to, enter into a contract for the services of, or attempt to entice away from either Group Company, any individual who is at the time of the offer or attempt, and was at the Completion Date, a director, officer or employee holding an executive or managerial position with either Group Company; or

(ii) procure or facilitate the making of any such offer or attempt by any other person; or

(g) at any time after Completion, use in the course of any business (for so long as used or registered in the name of either Group Company):

(iii) anything which is, in the reasonable opinion of the Buyer, capable of confusion with such words, mark, name, design or logo.

8.2 Covenants for the Benefit of the Buyer and Group

The covenants in this Clause 8 are intended for the benefit of the Buyer and each Group Company and apply to actions carried out by the Sellers in any capacity and whether directly or indirectly, on the Sellers’ own behalf, on behalf of any other person or jointly with any other person, including through a joint venture or partnership.

8.3 Exceptions to Restrictions

Nothing in this Clause 8 prevents the Sellers or any of them from holding or acquiring for investment purposes only, directly or indirectly, not more than five (5) percent of any class of shares or securities of any company whose shares or securities are listed or quoted on any recognised investment exchange.

8.4 Severance

Each of the covenants in this Clause 8 is a separate undertaking by each Seller in relation to himself and his interests and shall be enforceable by the Buyer and each Group Company separately and independently of their right to enforce any one or more of the other covenants contained in this Clause 8. Whilst each of the covenants in this Clause 8 is considered fair and reasonable by the Parties, if any restriction is found to be unenforceable, but would be valid if any part of it were deleted or the period or area of application reduced, the restriction shall apply with such modifications as may be necessary to make it valid and enforceable.

9 TAX

The provisions of the Tax Deed shall apply with effect from Completion.

10 GOVERNING LAW, DISPUTES AND ARBITRATION

(h) Relevant Claim means any claim (incorporating a Relevant Claim Estimate) by the Buyer against the Warrantors in respect of the Tax Deed or this Agreement or the Warranties (including any claim that has been notified to the relevant Sellers but that is contingent only), provided that, in respect of the five hundred thousand British Pounds referred to in paragraph (d)(iii), a claim may only be made against this amount in respect of the indemnity referred to in Clause 2.1(f) of the Tax Deed;

87

4. The Founders shall have twenty (20) Business Days after each Escrow Release Date to accept or dispute, in respect of each Unresolved Claim, the continued retention of the amount of the Relevant Claim Estimate applicable thereto. Failing dispute by at least three (3) of the Founders within such period, the Founders shall be deemed to have accepted such retention pending the Unresolved Claim in question being Determined. Such an acceptance shall be without prejudice to the Founders’ right to dispute the Unresolved Claim and shall not constitute an admission thereof.

5. If at least three (3) of the Founders notify the Buyer, within the period referred to in paragraph 4 that they dispute the continued retention in the Escrow Account of the amount of any Relevant Claim Estimate after either Escrow Release Date, such dispute may, unless resolved by the Founders and the Buyer, within a period of fifteen (15) Business Days from the date of such notification, be referred by the Founders or the Buyer to the decision of an independent firm of solicitors (the Legal Expert) to be appointed (in default of nomination by agreement between the Founders and the Buyer) by the President for the time being of the Law Society of Scotland on the written application of the Founders or of the Buyer (whichever applies first). The Legal Expert shall be required to determine on a prima facie basis whether the Relevant Claim is bona fide and, if it is, the amount of the likely prima facie liability of the Founders thereunder (the Legal Expert Determination Amount).

6. The amount to be retained in the Escrow Account in respect of any Relevant Claim following a Legal Expert determination shall be the Legal Expert Determination Amount. Where the Legal Expert Determination Amount is less than the Relevant Claim Estimate, the Buyer (through Lufkin Industries, Inc.) and the Founders shall, within five (5) Business Days of the Legal Expert determination, instruct the Escrow Agent to pay to the Sellers’ Solicitors, on the next Business Day immediately following the date of the receipt of such instruction, an amount equal to the difference by way of telegraphic transfer of funds for same day value to a bank account nominated by the Founders, provided that such transfer shall be capped at the amount that shall result in there being an amount not less than the applicable Scheduled Remaining Escrow Sum in the Escrow Account.

7. Any Legal Expert Determination shall be binding on the Buyer and the Founders for the purposes of determining whether there is to be continued retention of the Relevant Claim Estimate (or any proportion thereof) and the amount thereof, but shall neither be binding on, nor admissible as between, the Buyer and the Founders in any dispute or proceeding concerning the Relevant Claim itself or concerning any other Relevant Claim.

8. If any Relevant Claim is referred to the Legal Expert pursuant to paragraph 5:

(a) The Legal Expert shall act as an expert and not as an arbitrator and neither the Arbitration Act 1996 nor the Arbitration (Scotland) Act 2010 nor any earlier or later enactments on arbitration shall apply. The Legal Expert’s decision shall (in the absence of fraud or manifest error) be final and binding on the Parties for all the purposes of this Agreement;

(b) the Founders and the Buyer shall request the Legal Expert to notify his decision to the Founders and the Buyer in writing (stating reasons) within twenty (20) Business Days of being instructed;

(c) the Founders and the Buyer shall within ten (10) Business Days of the appointment of the Legal Expert each submit to him a written submission of its case and, if so directed by the Legal Expert, shall attend any hearing before him and oral submissions as required by him;

88

(d) without prejudice to their respective obligations set out in paragraph 8(b), the Founders and the Buyer shall each use all reasonable endeavours to co-operate with the Legal Expert in resolving the matters in dispute, and for that purpose shall provide to him all such information and documentation as he may reasonably require;

(e) the Legal Expert shall have the right to seek such professional assistance and advice as he may require in fulfilling his duties; and

(f) the fees of the Legal Expert (and any professional fees incurred by him) shall be borne as the Legal Expert shall direct but each of the Founders and the Buyer shall be responsible for their own costs of presenting its case to the Legal Expert. If the Legal Expert fails to make a direction in respect of such fees, the Buyer and the Founders shall bear one half of such fees each.

9. Subject to paragraph 8(a), where following any Escrow Release Date, there ceases to be any Relevant Claims (including Unresolved Claims) remaining and there is an amount standing to the credit of the Escrow Account in excess of the Scheduled Remaining Escrow Account, the Buyer (through Lufkin Industries, Inc.) and the Founders shall, within five (5) Business Days following the date of on which there are no Relevant Claims remaining, instruct the Escrow Agent to pay to the Sellers’ Solicitors, on the next Business Day immediately following the date of receipt of such instruction, an amount equal to the amount by which the balance standing to the credit of the Escrow Account is in excess of the Scheduled Remaining Escrow Sum by way of telegraphic transfer of funds for same day value to a bank account nominated by the Founders.

10. The amount of the Escrow Sum shall not be regarded as imposing any limit on the amount of any Relevant Claim. If an amount in respect of a Relevant Claim is not satisfied in full from the Escrow Sum, such Relevant Claim (to the extent not so satisfied) shall remain fully enforceable against the Founders subject to the terms of this Agreement.

11. The Escrow Sum shall be the first source, but not the sole source, to satisfy any claim by the Buyer in respect of a Relevant Claim.

12. Notwithstanding the foregoing provisions of this Part 9 of the Schedule, the Buyer shall not be entitled to the release to it of an amount from the Escrow Account in respect of a Relevant Claim to the extent that the Buyer has already made recovery in respect of that Relevant Claim pursuant to any other provision of this Agreement or otherwise in respect of such an amount.

13. The operation of this Part 9 of the Schedule in respect of Relevant Claims shall for the avoidance of doubt be subject to the limitations set out in Part 5 of the Schedule.
