COVENANTS

5.1 Non-Competition.

(a) Each of the Sellers, in order to induce the Buyers to enter into this Agreement and acknowledging that the goodwill associated with the Businesses to be acquired by the Buyers pursuant to this Agreement constitutes a significant portion of the Purchased Assets, expressly

covenants and agrees that during the Prohibited Period such Seller shall not, and such Seller shall cause entities under common Control not to, other than on behalf of the Buyers or any Affiliate of the Buyers, (A) engage in or carry on directly or indirectly any business in which the Businesses are engaged as of the date hereof (a “Competing Business”) anywhere in the world or (B) directly or indirectly, own, manage, operate or control any business, partnership, firm, corporation or other entity, which wholly or in a material part, engages in a Competing Business anywhere in the world. For purposes of this Section 5.1, any such business, individual, partnership, firm, corporation or other entity shall be deemed to be engaged in significant part in any business in which the Businesses are engaged if more than 15% of its gross revenues in any twelve (12) month period are attributable to operations that compete with the Businesses. In no event will the Buyers or any Affiliate of the Buyers be deemed to be a Competing Business. Unless otherwise provided, as used in this Agreement, “Prohibited Period” means five (5) years from and after the Closing Date.

(b) Each of the Sellers expressly covenants and agrees that during the Prohibited Period, such Seller will not, and will cause its Affiliates not to, other than on behalf of the Buyers and their Affiliates, directly or indirectly solicit, approach or entice away or cause to be solicited, approached or enticed away from the business of the Buyers or their Affiliates any Person who or which is a customer or supplier of the Buyers or any of their Affiliates in connection with the Buyers’ operation of the Businesses. Notwithstanding the foregoing, nothing shall prohibit the Sellers from soliciting, approaching or enticing away any customer or supplier of the Buyers or any of their Affiliates concerning commercial activities unrelated to the Businesses.

(c) The Sellers acknowledge and agree that the geographical restrictions and the length of the non-compete and non-solicitation periods are reasonable and narrowly drawn to impose no greater restraint than is necessary to protect the goodwill of the Businesses and to protect the Buyers’ legitimate interest in the enjoyment of the Businesses. Each of the Buyers and the Sellers intend that the covenants of Section 5.1(a) and Section 5.1(b) shall be deemed to be a series of separate covenants, one for each county or province of each and every state, territory or jurisdiction of each country within the world, and one for each month of the time periods covered by such covenants.

(d) To the extent that any part of this Section 5.1 may be invalid, illegal or unenforceable for any reason, it is intended that such part shall be enforceable to the extent that a court of competent jurisdiction shall determine that such part, if more limited in scope, would have been enforceable, and such part shall be deemed to have been so written and the remaining parts shall as written be effective and enforceable in all events and the Parties agree to request that such court enforce Section 5.1(a) as if so written. The Sellers agree that in the event a court of competent jurisdiction declares that there has been a breach by the Sellers of this Section 5.1, the term of any such covenant so breached shall be automatically extended for the period of time of the violation from the date on which such breach ceases or from the date of the entry by a court of competent jurisdiction of a final non-appealable order enforcing such covenant, whichever is later.

(e) If the Sellers or any of their Affiliates breach or threaten to commit a breach of any of the restrictive covenants set forth in this Section 5.1, then the Buyers shall have the

following rights and remedies against the Sellers, which are in addition to, and not in lieu of, any other rights and remedies otherwise available to the Buyers at Law or in equity for Sellers’ and/or their respective Affiliates’ actions:

(i) the right and remedy to have the restrictive covenants in this Section 5.1 specifically enforced against the Sellers and/or their respective Affiliates, including temporary restraining orders and injunctions by any court of competent jurisdiction, it being agreed by the Sellers that any breach or threatened breach by the Sellers or any of their respective Affiliates of this Section 5.1 would cause irreparable injury to the Buyers and that money damages would not provide an adequate remedy to the Buyers;

(ii) the right and remedy to require the Sellers to account for and pay over to the Buyers any monies and benefits derived or received directly or indirectly, from any transaction constituting a breach of this Section 5.1; and

(iii) the right and remedy to collect from the Sellers any costs and fees of Sellers and/or their respective Affiliates incurred in enforcing this Section 5.1, including reasonable attorneys’ fees and expenses, but only to the extent such costs and fees were incurred in connection with a successful enforcement of this Section 5.1.

5.2 Further Assurances.

(a) From time to time after the Closing, and without any further consideration, the Parties agree to execute, acknowledge and deliver all such additional deeds, assignments, bills of sale, conveyances, instruments, notices, releases, acquittances and other documents, and will do all such other acts and things, all in accordance with applicable Laws, as may be reasonably necessary to give effect to the transactions consummated by this Agreement and to collect and reduce to the possession of the Buyers the Purchased Assets and to effect the assumption by the Buyers of the Assumed Liabilities as specified in Section 2.2 hereof.

(b) If consent is not obtained prior to the Closing with respect to the assignment of any Purchased Contract, or any claim, right or benefit arising thereunder or resulting therefrom, the Sellers shall reasonably cooperate with the Buyers to assist them in obtaining such consent as soon as reasonably practicable; it being understood that the Sellers shall not be required to pay or commit to pay any person whose consent is being solicited any cash or other consideration, nor make any commitment to do the same, nor incur or agree to incur any liability due to such person in connection with obtaining such consent.

(c) Except as set forth on Schedule 5.2(c) of the Disclosure Schedules, If the Buyers are unable to obtain consent with respect to the assignment of any Purchased Contract as contemplated by Section 5.2(b) after the application of Sellers’ reasonable best efforts, the Sellers shall cooperate with the Buyers in an arrangement reasonably satisfactory to the Buyers under which the Buyers would obtain, to the extent practicable, the claims, rights and benefits with respect to such Purchased Contract as specified in Section 2.1 hereof and assume the Assumed Liabilities (but not any Excluded Liabilities) associated therewith and corresponding to the claims, rights and benefits obtained by the Buyers. The Parties agree that any such

arrangements contemplated by the Transition Services Agreement (defined below) shall be deemed reasonably satisfactory to the Buyers.

(d) The Sellers shall pay as soon as reasonably practicable to the Buyers all monies received by such Sellers for any products sold or services rendered following the Closing under any Purchased Contract or any claim, right or benefit arising thereunder not transferred to the Buyers at Closing.

(e) The Buyers shall pay as soon as reasonably practicable to the Sellers all monies received by the Buyers in settlement of any Accounts Receivable of the Sellers or otherwise in connection with any Excluded Assets.

5.3 Tax Matters.

(a) The Buyers shall be responsible for the payment of all transfer, sales, use, value-added, documentary, stamp, retailer occupation or other similar taxes (the “Transfer Taxes”) that arise by reason of the consummation of the transactions contemplated by this Agreement. The Buyers shall be responsible for the remittance of all Transfer Taxes to the appropriate taxing jurisdictions. Swiss VAT, if an, due and paid by the Swiss Seller to the Swiss Federal Tax Administration upon the transfer of the Swiss Tangible Assets shall be borne by the Swiss Buyer on the basis of an invoice provided by the Swiss Seller to the Swiss Buyer and complying notably with all formal requirements of Article 26 of the Swiss VAT law of June 12, 2009, so that the Swiss Buyer is in a position to recover such input VAT. Notwithstanding the foregoing, it is intended that the intangible Purchased Assets owned by the Swiss Seller will be sold as part of an export sale from the Swiss Seller to the U.S. Buyer as so called “immaterial services” within the meaning of Article 3, letter e, of the Swiss VAT law of June 12, 2009 and will not require the payment of any Transfer Taxes by the Buyers in respect thereof.

(b) Each of the Parties agrees to cooperate fully with each other Party to enable each Party to more accurately determine its own tax liability and to minimize such liability to the extent legally permissible. Each Party shall provide and make available to each other Party such records as a Party may reasonably request for the defense of any audit, examination, administrative appeal or litigation of any Tax Return or other similar governmental report or form.

(c) Subject to Section 5.3(a), the Sellers shall be liable for, and shall indemnify, defend and hold harmless the Buyers for, any and all liability for Taxes with respect to the ownership and/or operation of the Purchased Assets for any taxable period ending on or before the Closing Date (“Pre-Closing Tax Period”) and with respect to any taxable period that begins on or before the Closing Date (“Straddle Period”), for the portion thereof ending on the Closing Date. Except as provided in Section 5.3(d), in the case of any Straddle Period, the amount of Taxes with respect to the Purchased Assets allocable to the portion of the Straddle Period ending on the Closing Date shall be determined on an interim closing of the books basis.

(d) Ad valorem property Taxes imposed on or with respect to the Purchased Assets for the taxable period (for purposes of this section, “taxable period” means the period beginning on the assessment date for ad valorem property Taxes through the day before the next assessment

date for such Taxes) that contains the Closing Date shall be prorated between the Sellers and the Buyers based on the relative number of days prior to the Closing Date and on and after the Closing Date during the taxable period, with the Sellers being responsible for such prorated ad valorem property Taxes for the period prior to the Closing Date and the Buyers being responsible for such prorated ad valorem property Taxes for the period beginning on the Closing Date. Upon receipt of the ad valorem property Tax bills for the taxable period that includes the Closing Date, the party receiving such bills shall calculate the prorated ad valorem property Taxes and shall bill the other party for such prorated amount, with such prorated Tax amount to be paid to the billing party within ten (10) days of receipt of the request from the billing party. The party receiving the ad valorem property Tax bills shall be responsible for timely payment of the bills to the appropriate Governmental Authorities.

(e) The U.S. Seller and the U.S. Buyer agree to use the standard procedure set forth in Revenue Procedure 2004-53 with respect to wage reporting.

5.4 Public Statements. The Parties shall consult with each other prior to issuing any public announcement, statement or other disclosure with respect to this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby and neither the Sellers on one hand nor the Buyers on the other shall issue any such public announcement, statement or other disclosure without having first received the written consent of the other Party (such consent not to be unreasonably withheld), except as may be required by Laws or GAAP.

5.5 Cooperation in Connection with Regulatory Matters.

(a) From and after the date of this Agreement, the Sellers shall, and shall cause their respective Affiliates and their respective partners, members, shareholders, owners, officers, directors, managers, employees, counsel, financial advisors, accountants and agents to, use reasonable best efforts to (i) furnish to the Buyers as soon as reasonably practicable upon the reasonable request of the Buyers all such financial information relating to the Sellers and the Businesses in the Sellers’ possession as may be reasonably required by the Buyers to prepare the financial statements and other financial data required by Regulation S-K and Regulation S-X under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, and (ii) cooperate with the Buyers in connection with any governmental proceedings; provided, with respect to subpart (ii) of the preceding, that the Sellers shall not be required to take any action that would, in the good faith judgment of the Sellers, be unduly burdensome or otherwise materially adversely affect the Sellers or the Sellers’ business strategy or plans.

(b) The Buyers shall timely reimburse the Sellers for all out-of-pocket expenses (including fees and expenses of counsel, advisors, accountants and agents) incurred in connection with their obligations under Section 5.5(a).

(b) The Sellers shall not have any liability under Article VII for any breach of any representation or warranty of the Sellers contained in this Agreement, and no claims by the Buyers Covered Persons shall be so asserted, for any individual item where the Loss relating to such claim (or series of claims arising from the same or substantially similar facts or circumstances) is less than $50,000.

(c) The Buyers shall not have any liability under Article VII for any breach of any representation or warranty of the Buyers contained in this Agreement, and no claims by the Sellers Covered Persons shall be so asserted, for any individual item where the Loss relating to such claim (or series of claims arising from the same or substantially similar facts or circumstances) is less than $50,000.

(e) The Sellers Covered Persons will not be entitled to indemnity under Section 7.3 this Agreement for Losses with respect to any claim under Section 7.3 until the aggregate

7.5 Claims Procedures.

(a) In the event that any Proceeding is commenced by a third party involving a claim for which a party required to provide indemnification hereunder (an “Indemnifying Party”) may be liable to a party entitled to indemnification (an “Indemnified Party”) hereunder (a “Third Party Claim”), the Indemnified Party shall promptly notify the Indemnifying Party in writing of such Third Party Claim indicating the nature of such claim and the basis therefore (the “Claim Notice”) and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided that if the Indemnifying Party does not promptly take reasonable action to assume such defense, the Indemnified Party may lead the defense of such potentially indemnified claim and the Indemnifying Party shall be liable for all additional costs and expenses incurred by the Indemnified Party in connection therewith, provided further, that no failure of any Indemnified Party to give such Claim Notice and no delay on the part of the Indemnified Party in giving any such Claim Notice shall relieve the Indemnifying Party of any indemnification obligation hereunder except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

(b) An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, such counsel shall be at the expense of the Indemnifying Party). It being understood, however, that the Indemnifying Party shall not, in connection with any one such Proceeding, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all

Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties; provided, however, that in the case a single firm of attorneys would be inappropriate due to actual or potential differing interests or conflicts between such Indemnified Parties and any other party represented by such counsel in such Proceeding or otherwise, then the Indemnifying Party shall be liable for the fees and expenses of one additional firm of attorneys with respect to such Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld.

(c) No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless (A) such settlement includes a full and unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding, (B) does not contain any admission of wrongdoing or illegal conduct and (C) the Indemnifying Party has agreed in writing that it is liable to the Indemnified Party for an indemnification payment in respect of the full amount of the settlement.

7.6 Satisfaction of Claims for Indemnification. The Parties agree that in the event any Losses are determined to have been incurred as a result of an indemnification claim pursuant to Section 7.2(a), the Sellers shall have the right to first satisfy and discharge any such Losses by either (i) compensating the Buyers directly for such Losses and/or (ii) taking appropriate remedial action to remedy such Losses.

7.7 Exclusive Remedy. The remedies provided in this Article VII shall be the sole and exclusive remedies of the Parties, from and after the Closing, with respect to this Agreement and the transactions contemplated hereby. The Parties acknowledge and agree that the remedies available in this Article VII supersede any other remedies available at law or in equity. The Parties covenant not to sue or assert or threaten any claim or Proceeding other than those described in this Article VII as being available under the particular circumstances described in this Article VII. Notwithstanding the foregoing, nothing in this Article VII shall limit the right of any Indemnified Party (i) to pursue an action for or to seek remedies with respect to claims for Fraud, or (ii) to seek specific performance or other equitable relief pursuant to Article V.

7.8 No Reliance.

(a) THE REPRESENTATIONS AND WARRANTIES OF THE SELLERS CONTAINED IN ARTICLE III CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF THE SELLERS IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY. THE REPRESENTATIONS AND WARRANTIES OF THE BUYERS CONTAINED IN ARTICLE IV CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF THE BUYERS IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY.

EXCEPT FOR SUCH REPRESENTATIONS AND WARRANTIES (IN EACH CASE, AS MODIFIED BY THE DISCLOSURE SCHEDULES HERETO), EACH PARTY HEREBY DISCLAIMS ALL LIABILITY AND RESPONSIBILITY FOR ANY REPRESENTATION, WARRANTY, PROJECTION, FORECAST, STATEMENT, OR INFORMATION MADE, COMMUNICATED, OR FURNISHED (ORALLY OR IN WRITING) TO ANY OTHER PARTY OR ITS AFFILIATES OR REPRESENTATIVES (INCLUDING OPINION, INFORMATION, PROJECTION, OR ADVICE THAT MAY HAVE BEEN OR MAY BE PROVIDED TO ANY PARTY OR REPRESENTATIVE OF SUCH PARTY OR ANY OF ITS AFFILIATES).

(b) Notwithstanding any other provision of this Agreement, in no event shall any Party be liable for (and the term Losses shall exclude) punitive, special, incidental, indirect, consequential or lost profits damages of any kind or nature, regardless of the form of action through which such damages are sought, except for any such damages recovered by any third party against any Party in respect of which such Party would otherwise be entitled to indemnification pursuant to the terms hereof or in connection with claims for Fraud or willful breach of this Agreement.

7.9 Express Negligence. THE PARTIES HERETO INTEND THAT THE INDEMNITIES SET FORTH IN THIS ARTICLE VII BE CONSTRUED AND APPLIED AS WRITTEN ABOVE, NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY. WITHOUT LIMITING THE FOREGOING, BUT LIMITED TO THE EXTENT PROVIDED ABOVE, SUCH INDEMNITIES SHALL APPLY NOTWITHSTANDING ANY STATE’S “EXPRESS NEGLIGENCE” OR SIMILAR RULE THAT WOULD DENY COVERAGE BASED ON AN INDEMNIFIED PARTY’S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE.

5.5 FORCE MAJURE. Neither Party will be liable to the other Party on account of any loss or damage resulting from any delay or failure to perform all or any part of this License if such delay or failure is caused, in whole or in part, by events, occurrences, or causes beyond the control and without negligence of the Parties. Such events, occurrences, or causes will include, without limitation, acts of Gods, strikes, lockouts, riots, acts of war, acts of terrorism, earthquake, fire and explosions, but the inability to meet financial obligations is expressly excluded.

5.6 WAIVER. Any waiver of the provisions of this License or of a Party’s rights or remedies under this License must be in writing to be effective. Failure, neglect, or delay by a Party to enforce the provisions of this License or its rights or remedies at any time, will not be construed as a waiver of such Party’s rights under this License and will not in any way affect the validity of the whole or any part of this License or prejudice such Party’s right to take subsequent action. No exercise or enforcement by a Party of any right or remedy under this License will preclude the enforcement by such Party of any other right or remedy under this License or that such Party is entitled by law to enforce.

5.7 SEVERABILITY. If any term, condition, or provision in this License is found to be invalid, unlawful or unenforceable to any extent, the Parties shall endeavor in good faith to agree to such amendments that will preserve, as far as possible, the intentions expressed in this License. If the Parties fail to agree on such an amendment, such invalid term, condition or provision will be severed from the remaining terms, conditions and provisions, which will continue to be valid and enforceable to the fullest extent permitted by law.

5.8 GOVERNING LAW. This License shall be governed by and construed and enforced in accordance with the internal laws of the State of Texas without reference to its choice of law rules.

standard of care it uses with its own confidential information, all Confidential Information included in the Licensed Intellectual Property. For the purposes of this Section 5.9, the Licensee and its Affiliates shall each be a “Recipient” of all Confidential Information included in the Licensed Intellectual Property. Confidential Information shall not include, and no obligations of a Recipient under this License shall apply to, information that:

(a)	is or becomes available to the industry (e.g. available in the technical literature databases, or the like) or is in, or subsequently enters into the public domain through no act or omission of a Recipient prohibited by this License;

(b)	is received by a Recipient from a third party if such third party was not, to the knowledge of the Recipient, subject to any confidentiality obligation to the Party that is the Licensor of such Confidential Information;

(c)	is independently developed by the employees or agents of a Recipient without access to the Confidential Information provided by the Party that is the Licensor of such Confidential Information hereunder;

(d)	is approved for public release by written authorization of Licensor; or

(e)	is already known by the Recipient (as established by reasonable documentation) at the time of disclosure under this License.

5.10 COUNTERPARTS. This License may be executed in counterparts, each of which so executed will be deemed to be an original and such counterparts together will constitute one and the same License.

E-7

The Parties have executed and delivered this License as of the Effective Date.

WHEREAS, the Sellers and the Buyers are parties to an Asset Purchase Agreement dated as of November 1, 2011 (the “Asset Purchase Agreement”) (capitalized terms used but not otherwise defined herein have the meanings given such terms in the Asset Purchase Agreement); and

WHEREAS, it is a condition to consummation of the transactions contemplated by the Asset Purchase Agreement that the Parties execute and deliver this Agreement with respect to the provision by the Sellers of certain transition services to the Buyers;

NOW, THEREFORE, in consideration of the premises, agreements and covenants contained in this Agreement, and other good and valuable consideration provided under the Asset Purchase Agreement and as herein provided, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1. General Description of Services.

(a) The Sellers shall provide, or cause to be provided, to the Buyers the services explicitly described in Schedule A hereto (the “General Services”) in accordance with the terms set forth therein describing such General Services.

(b) Other than the General Services, no Seller shall be required to provide any services to the Buyers as a result of this Agreement.

(c) The Buyers may from time to time request that the Sellers provide services in addition the General Services for a term certain. Any such additional service that the Sellers, in their sole discretion, agree to provide shall be deemed an “Additional Service” (together with the General Services, the “Services”). The charges for any particular Additional Service shall be equal too the direct costs and expenses and a reasonable allocation of indirect costs attributable to the provision of such Additional Service by the Sellers. If requested by the Buyers prior to

providing any proposed Additional Service, the Sellers shall prepare and deliver to the Buyers a good faith estimate of the direct costs and expenses and allocable indirect costs associated with the provision of such proposed Additional Service. In no event shall the term for any Additional Service extent beyond 150 days from the Closing Date.

(d) The Parties acknowledge the transitional nature of the Services. Accordingly, as promptly as practicable following the execution of this Agreement, the Buyers agree to use reasonable best efforts to make a transition of each Service to their own internal organization or to obtain alternate third-party sources to provide the Services before the respective term of each Service is complete.

2. Charges.

(a) The Sellers shall charge the Buyers, and the Buyers shall pay to the Sellers, a fee in respect to each of the Services. For each General Service, such fee is set forth on Schedule A.

(b) In addition to the fee for each General Service set forth on Schedule A, in the event that the Sellers or any of their respective Affiliates incurs reasonable and documented out-of-pocket expenses in the provision of any Service, including license fees and payments to third-party service providers or subcontractors, but excluding payments made to employees of any of the Sellers or their respective affiliates (such included expenses collectively, the “Out-of-Pocket Costs”), the Buyers shall be charged the Out-of-Pocket Costs; provided, that the use of any third party for the provision of any Service hereunder (other than the use of a third party in the Ordinary Course of Business for the Businesses as conducted by the Sellers) shall be subject to the approval of the Buyers in their reasonable discretion.

3. Payment.

(a) No more frequently than once a month, the Sellers will invoice the Buyers for the Services provided to the Buyers since the generation of the last invoice. The Buyers will pay such invoice in immediately available funds by bank wire transfer to an account designated by the Sellers such that the funds are immediately available to the Sellers no later than the 10th calendar day after the date of the invoice. The Buyers and the Sellers agree that if the due date does not occur on a Business Day, the Sellers will receive the immediately available funds the next following Business Day. Delay in payment will result in the Buyers being responsible for interest at a rate of five percent (5%) per month, or the maximum rate allowed by any Law, whichever is less, on the outstanding amount of any unpaid invoice beginning on the day after the payment due date.

(b) If the Buyers disagree with any invoiced charge, the Buyers shall send written notice to the Sellers within five (5) days of receipt of such invoice specifying the reason for such disagreement, but shall pay the invoiced amount in full when due. The Parties shall negotiate in good faith to promptly resolve any such disagreement. The Sellers agree to afford the Buyers, upon reasonable notice, access to such information, records and documentation of the Sellers as the Buyers may reasonably request in order to verify the accuracy of the invoiced amounts; provided, that such access shall be during the Sellers’ ordinary business hours and shall not be

F-2

unduly burdensome or materially interfere with the Sellers’ business. If the Parties are unable to resolve any such dispute within 30 days, the Parties shall submit the dispute to a nationally recognized independent accounting firm mutually acceptable to the Buyers and the Sellers (the “Neutral Arbitrator”). The Neutral Arbitrator shall act as an arbitrator to determine the proper amount to be charged to the Buyers.

(c) The Buyers shall bear their own costs incurred in connection with the verification of the accuracy of any invoiced amounts and in consuming Services or performing activities.

4. Term.

(a) This Agreement will terminate when the last Service is performed in full in accordance with the terms hereof.

(b) For each Service, the Sellers will provide such Service for the period of time set forth on Schedule A for such General Service (or as agreed to by the Parties for such Additional Service).

(c) Notwithstanding any other provision of this Agreement, this Agreement will terminate with respect to any individual Service at any time upon the happening and continuance of any of the following events or conditions:

(i)	by the Sellers upon notice to the Buyers, if the Buyers are in material breach of any of its obligations hereunder and fails to remedy such breach within 30 days of receipt of written notice thereof from the Sellers;

(ii)	by the Buyers upon notice to the Sellers, if the Sellers are in material breach of any of their obligations hereunder and fail to remedy such breach within 30 days of receipt of written notice thereof from the Buyers; or

(iii)

upon the mutual written agreement of the Parties to terminate the Service.

(d) Notwithstanding anything contained herein to the contrary, any and all such Services provided hereunder may be earlier terminated by the Buyers upon fifteen (15) days’ prior written notice to the Sellers. For a termination of Services provided by the Sellers that occurs other than at an applicable billing cut-off date, the Buyers shall pay the actual costs and expenses as provided by this Agreement; where applicable, such costs and expenses may be prorated through the date such Services ceased. The Sellers agree and acknowledge that a partial termination of Services under this Agreement by the Buyers, and payment of the applicable prorated fees applicable to such Service by the Buyers, the Buyers shall no longer have any payment obligations pursuant to Section 3 hereof with respect to such Service. In addition, a partial termination of Services under this Agreement by the Buyers will have no effect on the Sellers’ obligation to perform any other non-terminated Services hereunder.

F-3

5. Standard of Service.

(a) Each Seller shall maintain such staff, support services and facilities as may be necessary to perform its responsibilities under this Agreement in keeping with the standards observed by such Seller while such Seller operated the Businesses. In providing Services under this Agreement, each Seller shall make use of the technology, equipment and working methods, and employ third-party service providers, consistent with its past practice. To the extent any such technology, equipment and working methods comprise Purchased Assets, the Buyers shall make such Purchased Assets available to the Sellers for the provision of Services. It is understood and agreed that each Seller is not in the business of providing Services to third parties and that the standard of care to which each Seller and any of the Seller’s employees performing Services hereunder shall be accountable shall be the standard of care used as of the date of the Asset Purchase Agreement by such Seller or its employees in furnishing comparable services to its own internal organization, and under no circumstances shall such Seller or its employees be held accountable for a greater standard of care.

(b) Except as set forth in Section 6(a), the Sellers make no warranties concerning the Services whatsoever. THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, AND EACH SELLER EXPRESSLY DISCLAIMS AND NEGATES, AND THE BUYERS EXPRESSLY WAIVE, ANY AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, CONCERNING THE SERVICES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

6. Limitations on Liability.

(a) The Sellers shall not be liable (including any liability for the acts and omissions of their respective employees, agents and sub-contractors) to the Buyers except with respect to the Sellers’ willful failure to perform, willful misconduct or gross negligence in performing the Sellers’ obligations under this Agreement.

(b) IN NO EVENT WILL EITHER PARTY BE LIABLE FOR ANY PUNITIVE, SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL OR LOST PROFITS DAMAGES OF ANY KIND OR NATURE, REGARDLESS OF THE FORM OF ACTION THROUGH WHICH SUCH DAMAGES ARE SOUGHT (WHETHER OR NOT CAUSED, IN WHOLE OR IN PART, BY A SELLER’S NEGLIGENT ACTS OR OMISSIONS, OR WHETHER BASED ON BREACH OF WARRANTY, BREACH OF AGREEMENT, STATUTE, STRICT LIABILITY OR OTHERWISE), SUFFERED OR INCURRED BY THE BUYERS IN CONNECTION WITH THIS AGREEMENT OR WITH RESPECT TO PROVISION OR FAILURE TO PROVIDE THE SERVICES.

7. Compliance with Laws. Each of the Sellers and the Buyers shall comply with all applicable Laws concerning the Services.

8. Suspension of Services; Force Majeure. Failure of the Sellers to perform the Services in accordance with this Agreement shall not be deemed a default and shall not subject the Sellers to any liability to the Buyers, if such failure is caused or occasioned by (a) compliance with any

F-4

Order or request of any Governmental Authority which is valid or reasonably believed to be valid, (b) the cancellation, suspension or material adverse modification of any Permit necessary to provide a Service or for the Buyers to operate any facility that receives a Service, or the inability to operate any such facility in compliance with applicable Laws, which results in a partial and material, or complete, shutdown of such facility, (c) any destruction of any facility necessary for the Sellers to provide a Service or any facility that receives a Service and the destruction affects the Parties’ operations hereunder; or (d) an act of God, public enemy, fire, explosion, equipment failure, flood, earthquake, tornado, hurricane, war, riot, sabotage, or other similar catastrophe, accident, embargo, strikes, lockouts or other industrial disturbances, shortage, delay or failure of supply of materials, power, utilities, labor, fuel or equipment, interruptions of or delay in transportation (including transmission system failure or breakdown) or by any other event or circumstances, whether of like or different character to the foregoing, but only to the extent any such event or circumstance is beyond the reasonable control of the Sellers. The obligations of the Sellers shall be excused and delayed by the period of time during which the provision of Services are affected by any such event, and any time period provided in the applicable Attachment for the Sellers to perform a Service shall be extended by the number of days during which the Sellers’ provision of Services is so affected.

9. Cooperation and Access.

(a) The Buyers acknowledges that certain Services to be provided by the Sellers are dependent upon information and related documents to be provided by the Buyers. The Parties agree to provide to each other all information and related documents reasonably requested to enable the Parties to perform hereunder and will comply with all such reasonable instructions as are necessary for the Parties to perform their obligations hereunder. In the event that a Service requires the Sellers or their Representatives or sub-contractors to access a facility or other asset of the Buyers, the Buyers shall provide full and open access to such facility or asset to the Sellers and their Representatives and sub-contractors for purposes of performing such Services.

(b) Each Party shall cooperate fully and provide such assistance as is reasonably required for the applicable Seller to provide the Services in the manner required by this Agreement.

10. Relationship of the Parties.

(a) Nothing in this Agreement shall be construed as creating any relationship between the Sellers and the Buyers other than as specifically set forth in this Agreement. No Party shall have any right, power or authority to assume, create, or incur any expense, liability or obligation, express or implied, on behalf of another Party, except as expressly provided herein. This Agreement is not intended to be nor shall be construed as a joint venture, association, partnership, or other form of a business organization or agency relationship.

(b) Each Seller is entering into this Agreement and will render Services as an independent contractor. Neither Buyer shall be considered the employer or joint employer of any Seller’s employees. Each Seller shall be solely responsible for determining and enforcing labor policies concerning its work force, including without limitation, the hiring, firing,

F-5

discipline and supervision of all its employees. Each Seller shall be solely responsible for any obligations relating to its employees, including without limitation, wages, benefits, taxes, expenses, severance pay and notification obligations, worker’s compensation, unemployment compensation, retiree medical and pension fund obligations and all other costs related to the employees necessary for the Services provided by such Seller hereunder.

11. Waiver. The failure of any Party at any time or times to enforce or require performance of any provision hereof will in no way operate as a waiver or affect the right of such Party at a later time to enforce the same. No waiver by any Party of any condition or of the breach of any term, covenant, representation or warranty contained in this Agreement, whether by conduct or otherwise, in any one or more instances, will be deemed to be or construed as a further or continuing waiver of any such condition or breach, or a waiver of any other condition or of any breach of any other term, covenant, representation or warranty contained in this Agreement. Any waiver of an obligation, agreement or condition contained herein will be valid and effective only if in writing and signed by the Party to whom such compliance is owed.

12. Notices. Any notice, demand or communication required or permitted under this Agreement shall be in writing and delivered personally, by reputable overnight delivery service or other courier or by certified mail, postage prepaid, return receipt requested, and shall be deemed to have been duly given (a) as of the date of delivery if delivered personally or by overnight delivery service or other courier or (b) on the date receipt is acknowledged if delivered by certified mail, addressed as follows; provided that a notice of a change of address shall be effective only upon receipt thereof:
