ARTICLE 4

REPRESENTATIONS AND WARRANTIES

OF SELLER

Except as set forth in the disclosure schedules delivered to Buyers at or prior to the date hereof and making reference to the particular section and/or subsection of this Agreement to which exception is being taken, Seller represents and warrants to Buyers and agrees as follows (it being understood that each reference to “Seller” in this Article 4 shall be deemed to be a reference to Seller and its subsidiaries and affiliates, collectively):

4.1 Corporate.

(a) Seller is a corporation duly organized, validly existing and in good standing under the Laws of the Province of Alberta, Canada. Seller has all requisite corporate power and authority to enter into this Agreement and all other agreements to be executed and delivered by Seller hereunder, to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby.

This Agreement and all other agreements, certificates and instruments contemplated by this Agreement to be executed and delivered by Seller or any subsidiary or affiliate of Seller have been or will be, at or prior to the Closing, duly executed and delivered by Seller or such subsidiary or affiliate and constitute legal, valid and binding obligations of Seller or the applicable subsidiary or affiliate of Seller enforceable against such party in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors' rights generally and to the principles of equity (whether enforcement is sought in a proceeding in equity or at law).

(c) Neither the execution, delivery or performance of this Agreement and all other agreements contemplated hereby nor the consummation of the transactions contemplated hereby or thereby nor compliance with the provisions hereof or thereof by Seller and its subsidiaries and affiliates will, with or without the passage of time or the giving of notice, or both, (i) conflict with, constitute a breach, violation or termination of any provision of, or constitute a default under, any Assigned Contracts or any Material Contracts to which Seller or any subsidiary or affiliate of Seller is a party or by which any such party is bound or to which its properties or assets are subject, (ii) result in an acceleration or increase of any amounts due from Seller or any subsidiary or affiliate of Seller to any person, (iii) conflict with or violate the organizational documents of Seller or any subsidiary or affiliate of Seller, (iv) result in the creation or imposition of any Lien against the Assets, Seller, any subsidiary or affiliate of Seller or any of their respective properties or assets, (v) violate any Laws or any other restriction of any kind or character applicable to the Assets, Seller, any subsidiary or affiliate of Seller or any of their respective properties or assets, or (vi) require notice to or consent of any Governmental Authority or third party.

4.2 No Adverse Action. There are no actions, suits, claims or legal, administrative, arbitration or other proceedings or governmental investigations or examinations pending or, to Seller's knowledge, threatened or injunctions or orders entered, pending or, to Seller's knowledge, threatened against Seller or its business, property or assets, at Law or in equity, before or by any Governmental Authority relating to or arising from the Business or the Assets, or which seek to restrain or prohibit the consummation of the

transactions contemplated hereby.

4.3 Title to the Assets; Condition. Seller has good and indefeasible title to the Assets, free and clear of all Liens except for the Permitted Encumbrances. Upon consummation of the transactions contemplated hereby, Buyers or their designated affiliates will have acquired good and indefeasible title in and to all of the Assets, free and clear of all Liens except for the Permitted Encumbrances. The transfer of the Assets from Seller to Buyers or their designated affiliates will not violate any fraudulent transfer Laws or any other Laws. All of the tangible Assets are in good, serviceable condition and fit for the particular purposes for which they are used in the Business, subject only to normal maintenance requirements and normal wear and tear reasonably expected in the ordinary course of business. All supplies are suitable and usable for their intended purposes, and none of such items is below standard quality, obsolete or obsolescent.

4.4 Intangible Properties.

(a) Ownership. Seller is the sole and exclusive owner of all right, title and interest in and to the Seller IP, free and clear of all Liens except for the Permitted Encumbrances. Seller has received no actual notice or claim (whether written, oral or otherwise) challenging Seller's ownership of any of the Seller IP by Seller (in whole or in part) or suggesting that any other person has any claim of legal or beneficial ownership with respect thereto, nor to the knowledge of Seller is there a reasonable basis for any claim that Seller does not own the Seller IP. Except with respect to the Permitted Encumbrances, Seller has the unrestricted right to transfer all right, title, and interest in and to the Seller IP to Buyers and their designated affiliates without impairing or limiting any rights therein.

(b) Validity and Enforceability. To the knowledge of Seller, the Seller IP is valid, enforceable and subsisting, without material qualification, limitation or restriction thereon or on the use thereof. The Seller has not received actual notice of any claim (written, oral or otherwise) challenging or questioning the validity or enforceability of any material part of the Seller IP or indicating an intention on the part of any person to bring a claim that any material part of the Seller IP is invalid or unenforceable or has been misused.

(c) Patent. Exhibits “B-1” and “B-2” set forth an accurate and complete list of all patents in which Seller has ownership rights or rights to use, sell and license, as the case may be, and which are employed by Seller in its operation of the Business as it is currently conducted or proposed to be conducted. The Patents have not been and are not now involved in any interference, reissue or reexamination proceeding, and, to the knowledge of Seller, no such action is or has been threatened. To the knowledge of Seller, there are no facts or circumstances that would have barred issuance of the Patents, including no relevant prior art of which Seller has knowledge that was not disclosed during the prosecution of the applications for the Patents but which if such prior art had been disclosed may have affected the prosecution thereof or the scope of the patent claims ultimately granted in respect thereof.

(d) Maintenance of Confidentiality. Seller has taken steps that are reasonable to maintain the confidentiality of the Trade Secrets. None of the Trade Secrets has been disclosed nor is the Seller under any obligation (contractual or otherwise) to disclose the Trade Secrets except under a written or verbal confidentiality agreement or undertaking or license agreement or sales representative agreement. To the knowledge of Seller, (i) no such agreement or undertaking has been breached, and (ii) there has been no disclosure of the Trade Secrets such that Seller may not enforce rights in the Trade Secrets.

(e) Maintenance. Seller has not taken any action or failed to take any action of which it has knowledge, including the manner in which Seller has conducted its business or used or enforced or failed to use or enforce the Patents, that would result in abandonment, cancellation, forfeiture, relinquishment, invalidation or unenforceability of the Patents. The Patents have been registered and obtained in accordance with all material applicable legal requirements.

(f) Licenses. Except as reflected among the Permitted Encumbrances (if applicable), Seller has not granted any licenses, agreements not to xxx, or similar rights in the Seller IP to any person. Except with respect to licenses of commercial off-the-shelf Software, and except pursuant to the Permitted Encumbrances (if applicable), Seller is not required, obligated, or under any liability whatsoever, to make

any payments by way of royalties, fees or otherwise to any owner, licensor of, or other claimant to any Seller IP, or other third party, with respect to the use thereof or in connection with the operation of the Business as it is currently conducted or proposed to be conducted.

(g) No Infringement. Use of the Seller IP and operation of the Business as it is currently conducted or proposed to be conducted by Seller is not subject to and has not been subject to any pending or threatened challenge or claim or demand of infringement, misappropriation, violation, dilution or unauthorized use, and there is no reasonable basis upon which any such claim could be made. Except as reflected among the Permitted Encumbrances (if applicable), to Seller's knowledge no third party is misappropriating, infringing, diluting or violating any Seller IP. No Seller IP is subject to any outstanding order, judgment, decree, stipulation, or agreement restricting the use thereof by Seller or restricting the sale, transfer, assignment or licensing by Seller or its successors or assigns.

(h) Unburdened Transfer. The due execution and performance of this Agreement will not result in the loss or impairment of Buyers' or their designated affiliates' right to own or use any of the Seller IP.

To Seller's knowledge, there has not occurred any breach or default under any Material Contract on the part of the other parties thereto, and no event has occurred which with the giving of notice or the lapse of time, or both, would constitute a default under any Material Contract. There is no dispute between the parties to any Material Contract as to the interpretation thereof or as to whether any party is in breach or default thereunder, and no party to any Material Contract has indicated its intention to, or suggested it may evaluate whether to, terminate any Material Contract.

6.2 Information. Each party will promptly inform the other party in writing of any litigation commenced against such party with respect to (a) the transactions contemplated by this Agreement or (b) the Business or the Assets.

6.3 Covenant Against Competition.

(a) As an essential consideration for the obligations of Buyers under this Agreement, Seller hereby agrees and covenants that from and after the Closing Date and until the third anniversary thereof:

(i) Seller and its subsidiaries shall not, for whatever reason and with or without cause, either individually or in partnership or jointly or in conjunction with any Person or Persons as principal, agent, employee, stockholder, owner, investor, partner or in any other manner whatsoever (other than a holding of shares listed on a United States or Canadian stock exchange or automated quotation system that does not exceed one percent of the outstanding shares so listed), directly or indirectly, engage in the Business anywhere in the world, or otherwise render services to or on behalf of that segment of any enterprise which competes with the Business; or

(ii) Seller and its subsidiaries shall not, directly or indirectly, either for themselves or any other Person, (A) induce or attempt to induce any Transferred Employee or other employee of Buyers or any of their affiliates primarily engaged in the conduct of the Business to leave the employ of Buyers or any of their affiliates, (B) in any way interfere with the relationship between Buyers or any of their affiliates and any Transferred Employee or other employee of Buyers or any of their affiliates primarily engaged in the conduct of the Business, or (C) employ, or otherwise engage as an employee, independent contractor or otherwise, any Transferred Employee or other employee of Buyers or any of their affiliates primarily engaged in the conduct of the Business, provided that nothing precludes Seller from hiring any Transferred Employee who (1) initiates contact with Seller pertaining to employment or (2) responds to publicly advertised position with Seller. Buyers shall not hire any other employee of Seller for employment within the Business for a period of two (2) years from the Closing Date, subject to the reciprocal application of the exceptions set for the in the preceding sentence.

(b) If a Buyer believes that Seller or any subsidiary or affiliate of Seller has violated the provisions of this Section 6.3, such Buyer shall have the right to seek relief from any court of competent jurisdiction against such party. Seller acknowledges that money damages alone may not adequately

compensate such Buyer in the event of a breach of the covenants of this Section 6.3. Therefore, Seller agrees that in addition to all remedies available at law, in equity or under this Agreement, such Buyer shall be entitled to injunctive relief for the enforcement of this covenant.

(c) Seller agrees that the covenants in this Section 6.3 are reasonable with respect to their duration and scope. The covenants in this Section 6.3 are severable and separate, and the unenforceability of any specific covenant in this Section 6.3 is not intended by any party hereto to, and shall not, affect the provisions of any other covenant in this Section 6.3. If any court of competent jurisdiction determines that the duration or scope of Section 6.3 are unreasonable as applied to Seller or any of its subsidiaries, the parties hereto acknowledge their mutual intention and agreement that those restrictions be enforced to the fullest extent the court deems reasonable, and thereby shall be reformed to that extent.

(d) All the covenants in this Section 6.3 are intended by each party hereto to, and shall, be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Seller against a Buyer, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by such Buyer of any covenant in this Section 6.3. It is specifically agreed that the period specified in this Section 6.3 shall be computed by excluding from that computation any time during which Seller is in violation of any provision of Section 6.3. Buyers and Seller hereby agree that this Section 6.3 is a material and substantial part of the transactions contemplated by this Agreement. The covenants contained in this Section 6.3 shall not be affected by any breach of any other provision hereof by any party hereto.

6.4 Further Assurances. The parties will execute, acknowledge and deliver or cause to be executed, acknowledged and delivered to each other after the Closing such further instruments of transfer, assignment and conveyance (in form and substance reasonably satisfactory to Buyers), and take such other action as may reasonably be required to effectively carry out the transfer of the Assets and the Business, free and clear of all Liens (other than Permitted Encumbrances) and the consummation of the matters contemplated by this Agreement, and any other document reasonably requested by Buyers in connection with this Agreement.

6.5 Confidentiality; Public Announcement. All information disclosed by any party to this Agreement to the other party shall be governed by the Confidentiality Agreement between Seller and STC dated February 17, 2012 (the “Confidentiality Agreement”), and such Confidentiality Agreement shall survive any termination of this Agreement. Excluding required regulatory filings, Seller shall not, without the prior approval of Buyers, issue, or permit any of its partners, directors, officers, employees, agents, affiliates or brokers to issue, any press release or other public announcement with respect to this Agreement or the transactions contemplated hereby, provided that Seller shall consult with Buyers prior to making any required regulatory filings with respect to this Agreement or the transactions contemplated hereby.

6.6 Volant/Noetic Agreements. In the event that consent or approval is not obtained to transfer to Buyers Seller's rights under the Agreement (the “Noetic Agreement”) dated April 11, 2007 between Seller and Noetic Engineering Inc. to the extent attributable to the Business, to the extent practicable, Seller and Buyers shall effect alternative arrangements in the form of a license, sublicense or other agreement in form and substance reasonably satisfactory to Buyers until such time as such consent or approval has been obtained which results in Buyers receiving all of the benefits of Seller and bearing all the liabilities and other obligations of Seller with respect to the Noetic Agreement to the extent attributable to the Business.

6.7 Employee Matters.

(a) From the date that is mutually agreed upon between Buyers and Seller (which shall not be later than 10 days after the date hereof) through the Closing Date, Seller shall cooperate with Buyers in permitting Buyers to interview, on a voluntary basis, each Employee so as to make selection decisions and communicate to such Employees any information concerning employment offers and employment with Buyers after the Closing Date. During normal business hours, Seller shall allow additional meetings by representatives of Buyers with such Employees upon the reasonable request of Buyers, provided that the timing, number and length of such meetings are not unreasonable as determined by Seller in good faith.

(b) Prior to the Closing Date, Buyers shall deliver, in writing, an offer of employment (on an “at will” basis) to those Employees identified by Buyers on a schedule to be delivered to Seller prior to the Closing Date to commence (i) in the case of an Employee who is actively at work on the Closing Date, upon the Closing Date, (ii) in the case of an Employee who is on approved leave on the Closing Date, upon such Employee's report to his or her assigned work location and the inception of his or her rendering services for compensation immediately upon the end of the approved leave or (iii) in the case of an Employee who is not actively at work on Closing Date and is not on approved leave, such date as Buyers may determine, in each case subject to Buyers' standard conditions for new employees. The terms of employment, salaries, bonuses and benefit plans of each such Employee shall be consistent with Buyers' standard employment packages for comparably situated employees. Such individuals who accept such offer by the Closing Date are hereinafter referred to as the “Transferred Employees.” Subject to applicable Laws, on and after the Closing Date, Buyers shall have the right to dismiss any or all Transferred Employees at any time, with or without cause, and to change the terms and conditions of their employment (including compensation and employee benefits provided to them).

Buyers shall have no responsibility for, and Seller shall be responsible for, any and all liabilities, obligations and claims of any kind arising out of employment of any employees by Seller before the Closing Date and the transfer or termination of employment of any employees by Seller.

(e) To the extent permitted by applicable Laws, Seller shall use its best efforts to encourage each Employee to whom an offer is made by Buyers pursuant to Section 6.7(b) to accept such offer of employment (other than the payment of monies, except as provided in the immediately following sentence of this Section 6.7(e)), including communicating to such Employees that Seller will not continue to employ such Employees beyond the Closing Date. Seller shall reimburse Buyers one half of the bonus amount (the “Commencement Bonus”) payable to each Employee listed on Schedule 6.7(e) (each, a “Key Employee”) upon the commencement of such Key Employee's employment with Buyers, Seller's reimbursement obligation not to exceed $10,000 per Key Employee. The Commencement Bonuses will be paid pursuant to the terms embodied in the employment offers delivered to each Key Employee by Buyers.

(f) Nothing herein shall be deemed or construed to (i) give rise to any rights, claims, benefits, or causes of action to any Employee or (ii) prevent, restrict, or limit Buyers following the Closing from modifying or terminating their pension or other benefit plans, programs or policies from time to time as they may deem appropriate.

6.8 Tax Matters.

(a) Property Taxes. Liabilities or credits for ad valorem, personal property, and other similar Taxes (“Property Taxes”), if any, with respect to the Assets shall be prorated through the Closing Date (on the basis of the assessed value of the Assets and the rate of Tax for the current year or, if the assessed value of any Assets or the rate of Tax with respect thereto has not been determined prior to the Closing Date, the value and the rate with respect to such Assets shall be determined on the basis of the value or rate from the most recent prior year in which such value or rate was determined). Seller shall be responsible for all

such prorated Property Taxes attributable to the period prior to the Closing Date, STC shall be responsible for all other Property Taxes attributable to the US Assets, and XXXX shall be responsible for all other Property Taxes attributable to the Non-US Assets. Promptly upon receipt, Seller or a Buyer, as appropriate, shall provide the other party with copies of all bills or invoices for such Property Taxes which the other party is responsible pursuant to this Section 6.8(a). The resulting amount payable shall be paid promptly or otherwise contested in good faith.

(b) Transfer Taxes. All use, transfer, or similar Taxes (“Transfer Taxes”) payable in connection with the transactions contemplated by this Agreement shall be borne, on the one hand, 50% by Seller and, on the other hand, 50% by Buyers, regardless of whether the Governmental Authority seeks to collect such Transfer Taxes from Seller or Buyers or their subsidiaries or affiliates. Buyers shall timely file or cause to be filed all necessary documents (including all Tax Returns) with respect to such Transfer Taxes.

(c) Other Taxes. Seller shall be responsible for and pay all Other Taxes attributable to the ownership, use, operation, or disposition of the Assets for any taxable period (or portion thereof) ending on or before the Closing Date. For this purpose, “Other Taxes” shall mean all Taxes other than Property Taxes and Transfer Taxes.

(d) Refunds. If either Buyer, its subsidiaries or affiliates receive a refund of any Taxes that Seller is responsible for hereunder, or if Seller, its subsidiaries or affiliates receive a refund of any Taxes that either Buyer is responsible for hereunder, the party receiving such refund shall, within 30 days after receipt of such refund, remit it to the party who has responsibility for such Taxes hereunder.

(e) Cooperation. Buyers and Seller shall furnish or cause to be furnished to each other, as promptly as practicable, such information and assistance relating to the Assets as is reasonably necessary for (i) the preparation and filing of any Tax Return, claim for refund, or other required or optional filings relating to Tax matters, (ii) the preparation for any Tax audit or Tax protest, or (iii) for the prosecution or defense of any suit or other proceeding relating to Tax matters.

(f) Tax Elections and Accounting Methods. Seller shall not (and shall cause its subsidiaries and affiliates not to) make, modify or revoke any election with regard to Taxes or make any material change in any Tax accounting method with respect to the Assets, except to the extent that such action would not affect Buyers' or their subsidiaries' or affiliates' liability for Taxes with respect to the Assets for any taxable period (or portion thereof) beginning after the Closing.

6.9 Limited Use License Back to Seller for Drilling Optimization IP. Buyers agree to grant to Seller, from and after the Closing, a perpetual, irrevocable, non-exclusive, royalty-free, fully paid-up, worldwide license in fields of use other than the Business in and to U.S. Patent Application Nos. 13/333,027 and 61/562,257, future foreign equivalents, and patent applications claiming priority thereto, and associated copyrights and software created by Seller prior to the Closing (collectively “Drilling Optimization IP”) in connection therewith, to practice, design, make, have made, operate, sell, offer for sale, import, have operated and use the Drilling Optimization IP. This license provided in this Section 6.9 (the “License”) is personal to the Parties, and no Party may assign such license or any right or obligation under the License without the prior written consent of the other Party (other than in connection with a transaction effected solely for the purposes of changing the form or jurisdiction of organization of an entity, or a reorganization or transaction with or among Seller and any of its affiliates where substantially all of the business of Seller and any of its affiliates that was, immediately prior to such transaction, subject to the License remains, immediately after such transaction, subject to the License), which consent will not be unreasonably withheld. Notwithstanding the above, the License may be assigned by any Party without the other Parties' consent as part of a sale or transfer of a substantial portion of its business, provided, however, such assignment shall extend solely to that portion of the business sold or transferred to the Assignee and does not extend to any other activities. Any assignment or transfer in violation of this Section 6.9 shall be null and void. Subject to the foregoing, the License shall be binding upon and inure to the benefit of the Parties and their permitted successors and assigns. Notwithstanding the above, if Seller creates one or more separate legal entities from Seller, divisions, enterprises, spinoffs, or business units, such entity shall have the rights afforded to Seller hereunder.
