purpose hereunder (other than Section 7.01), and neither Purchaser nor any Affiliate of Purchaser shall have any claim or recourse against Seller or its directors, officers,

---



employees, Affiliates, controlling persons, agents, advisors or representatives with respect to such breach if Purchaser or any Affiliate of Purchaser had, prior to the Closing, actual knowledge of such breach, it being
acknowledged that Purchaser or its relevant Affiliates have actual knowledge of the Electroandes Information as of September 7, 2007; and

Section 9.07.Notice of Loss; Third Party Claims.

(a)     An
Indemnified Party shall give the Indemnifying Party notice of any matter which

indemnification under this  Agreement within 60 days of such determination stating
the amount of the Loss, if known, the method of computation thereof, and containing
a reference to the provisions of this Agreement in respect of which such right
of indemnification is claimed  or arises.

(b)If an Indemnified Party shall receive notice of any action, audit, claim, demand or assessment (excluding an action, audit, claim, demand
or assessment relating to Taxes which are covered by Section 9.13 hereof) (each, a Third Party Claim) against it which may give rise to a claim for Loss under this Article IX, within 30 days of the receipt of such notice, the Indemnified
Party shall give the Indemnifying Party written notice of such Third Party Claim. The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives
notice of its intention to do so to the Indemnified Party within 15 days of the receipt of such written notice from the Indemnified Party. If the Indemnifying Party elects to undertake any such defense against a Third Party Claim, the Indemnified
Party may participate in such defense at its own expense. The Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, all witnesses, pertinent records, materials and information in
the Indemnified Partys possession or under the Indemnified Partys control relating thereto. If the Indemnifying Party elects to direct the defense of any such claim or proceeding, the

---



Indemnified Party shall not pay, or permit to be paid, any part of such Third Party Claim unless the Indemnifying Party consents in writing to such payment or unless the Indemnifying Party withdraws from the defense of such Third
Party Claim liability or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Party is entered against the Indemnified Party for such Third Party Claim. If the Indemnified Party assumes the defense of any
such claims or proceeding pursuant to this Section 9.07 and proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the Indemnified Party shall give the Indemnifying Party
prompt written notice thereof and the Indemnifying Party shall have the right to participate in or reject such settlement and assume (or reassume as the case may be) the defense of such claims or proceeding. The Indemnifying Party shall have the
right to settle any Third Party Claim for which it obtains a release of the Indemnified Party in respect of such Third Party Claim or to which settlement the Indemnified Party consents in writing, such consent not to be unreasonably withheld or
delayed.

Section 9.08.Remedies. The parties hereto acknowledge and agree that (a) following the Closing, the
indemnification provisions hereof shall be the sole and exclusive remedies of the parties hereto for any breach by the other party of the representations and warranties in this Agreement and (b) notwithstanding anything herein to the contrary, no
breach of any representation or warranty contained herein shall give rise to any right on the part of the parties hereto after the consummation of the purchase and sale of the Interests to rescind this Agreement or any of the transactions
contemplated hereby. Each party hereto shall take all reasonable steps to mitigate its Losses upon and after becoming aware of any event which could reasonably be expected to give rise to any Losses.

Section 9.09.Tax Matters. Notwithstanding anything to the contrary herein, no party hereto shall be entitled
to indemnification for any and all Tax matters except as expressly provided in Sections 9.10 and 9.11.

Section 9.10.Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes

Purchaser shall file all necessary Tax Returns and other documentation with respect to any such Transfer Taxes, and, if required by Law of any Governmental or Regulatory Authority of any country, Seller will, and will cause TEC and its Affiliates
to, join in the execution of any such Tax Returns and other documentation and will cooperate with Purchaser to take such commercially reasonable actions as will minimize or reduce the amount of such transfer Taxes.

(a)      From and after the Closing, Seller agrees to indemnify Purchaser against all Indemnified Taxes other than those reserved for in the Electroandes Financial Statements.

than Indemnified Taxes), and (ii) any and all Taxes arising from or in connection with any breach by Purchaser of any of its covenants or obligations under this Agreement.

---



(c)In the case of Taxes of TEC, AenP or Electroandes that are payable with respect to a Straddle Period, the portion of any such Tax that is
allocable to the portion of the taxable period ending on the date of the Closing shall be:

(i)      in the case of Taxes that are either (x) based upon or related to income or receipts or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal,
tangible or intangible) deemed equal to the amount which would be payable (after giving effect to amounts which may be deducted from or offset against such Taxes) if the taxable period ended on the date of the Closing; and

(ii)     in
the case of Taxes imposed on a periodic basis, such shall be deemed to be the
amount of such Taxes for the entire Straddle Period (after giving effect to amounts
which may be deducted from or  offset against such Taxes) (or, in the case of
such Taxes determined on an arrears basis, the amount of such Taxes for the immediately
preceding period), multiplied by a fraction the numerator of which is the number
of days in the period ending on  the date of the Closing and the denominator
of which is the number of days in the entire Straddle Period. In the case of
any Tax based upon or measured by capital (including net worth or long-term debt)
or intangibles, any amount thereof required to  be allocated under this Section
9.11(b) shall be computed by reference to the level of such items on the date
of the Closing.

(d)Payment by the Indemnifying Party of any amount due under this Section 9.11 shall be made within 10 days following written notice by the
Indemnified Party that payment of such amounts to the appropriate taxing authority is due;provided,however, that Purchaser shall
comply with its obligation to notify promptly Seller under Section 9.13(a); andprovidedfurther, that the Indemnifying Party shall
not be required to make any payment earlier than two days before it is due to the appropriate taxing authority. Notwithstanding anything to the contrary herein, if Seller receives an assessment or other notice of Taxes due with respect to TEC, AenP
or Electroandes for which Seller is not responsible, in whole or in part, pursuant to paragraph (a) of this Section 9.11, then Purchaser shall pay such Taxes, or if Seller pays such Taxes, then Purchaser or TEC shall pay to Seller the amount of such
Taxes for which Seller is not responsible within 5 days following such payment. In the case of a Tax that is contested in accordance with the provisions of Section 9.13, payment of the Tax to the appropriate taxing authority will be considered to be
due no earlier than the date a final determination to such effect is made by the appropriate taxing authority or court.

(e)Notwithstanding anything to the contrary contained in this Agreement, Sellers shall not be liable for any claim for indemnification
pursuant to Section 9.11(a) with respect to any Tax Return unless and until the aggregate amount of indemnifiable Taxes which may be recovered from Seller equals or exceeds $100,000 with respect to such Tax Return.

Section 9.12.Tax Refunds and Tax Benefits.

(a)      Any Tax refund, credit or similar benefit (including any interest paid or credited with respect thereto) relating to Indemnified Taxes shall be the property of Seller, and if received by
Purchaser, AenP or TEC shall be paid over promptly to Seller. Any credit, refund or similar benefit resulting from an overpayment of Taxes of TEC, AenP or Electroandes for a

---



Straddle Period shall be prorated based upon the method employed in Section 9.1l(c) taking into account the type of Tax to which the refund relates. Purchaser shall, if Seller so requests and at Sellers expense, cause TEC,
AenP, Electroandes or other relevant entity to file for and use reasonable commercial efforts to obtain and expedite the receipt of any refund to which Seller is entitled under this Section 9.12. Purchaser shall permit Seller to participate in the
prosecution of any such refund claim.

(b)Any amount otherwise payable by Seller under Section 9.11 shall be reduced by any Tax benefit available to Purchaser, AenP, TEC or
Electroandes arising in connection with any underlying adjustment resulting in the obligation of Purchaser, AenP Electroandes or TEC to pay Taxes or other amounts for which Seller is responsible under Section 9.11 or the accrual or payment of such
Taxes (including the net present value of any Tax benefit relating to subsequent taxable years, calculated using a discount rate of 8% and assuming the highest applicable combined statutory rate of Tax then in effect).

(c)Any amount otherwise payable by Purchaser under Section 9.11 shall be reduced by any Tax benefit available to Seller arising in connection
with any underlying adjustment resulting in the obligation of Seller to pay Taxes or other amounts for which Purchaser is responsible under Section 9.11 or the accrual or payment of such Taxes (including the net present value of any Tax benefit
relating to subsequent taxable years, calculated using a discount rate of 8% and assuming the highest applicable combined statutory rate ofTaxthenineffect).

Section 9.13.Contests.

(a)      After the Closing, Purchaser shall promptly notify Seller in writing of the proposed assessment or the commencement of any Tax audit or administrative or judicial proceeding or of any demand or
claim on TEC, AenP, or Electroandes which, if determined adversely to the taxpayer or after the lapse of time, could be grounds for indemnification by Seller under Section 9.11. Such notice shall contain factual information (to the extent known to
Purchaser) describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any taxing authority in respect of any such asserted Tax liability. If Purchaser fails to give Seller prompt
notice of an asserted Tax liability as required by this Section 9.13, then Seller shall not have any obligation to indemnify for any loss arising out of such asserted Tax liability, but only to the extent that failure to give such notice results in
a detriment to Seller.

(b)In the case of a Tax audit or administrative or judicial proceeding (a Contest) that relates to Indemnified Taxes, Seller shall
have the sole right, at its expense, to control the conduct of such Contest. Seller shall consult with Purchaser and shall keep Purchaser reasonably informed with respect to any such Contest.

(c)With respect to Straddle Periods, Seller may elect to direct and control, through counsel of its own choosing, any Contest involving any
asserted Tax liability with respect to which indemnity may be sought from Seller pursuant to Section 9.11. If Seller elects to direct a Contest, Seller shall within 90 days of receipt of the notice of asserted Tax liability notify Purchaser of its
intent to do so, and Purchaser shall cooperate and shall cause AenP, TEC

---



and Electroandes to cooperate fully, in such Contest. If Seller elects not to direct the Contest, Purchaser may assume control of such Contest (at Purchasers expense). However, in such case, none of Purchaser, AenP, TEC or
Electroandes may settle or compromise any asserted liability without prior written consent of Seller;provided,however, that
consent to settlement or compromise shall not be unreasonably withheld. In any event, Seller may participate in the Contest.

(d)Purchaser and Seller agree to cooperate, and Purchaser agrees to cause AenP, TEC and Electroandes to cooperate, in the defense against or
compromise of any claim in any Contest.

all Taxes shown as due and payable on such Tax Returns shall be the responsibility of Purchaser (including any Taxes reserved for on the Electroandes Financial Statements), except for such Taxes which are the responsibility of Seller pursuant to
Section 9.11(c) . Such Tax Returns shall be prepared on a basis consistent with those prepared for prior taxable periods unless a different treatment of any item is required by an intervening change in Law. With respect to any Tax Return required to
be filed with respect to TEC, AenP or Electroandes for a Straddle Period and as to which Taxes are allocable to Seller under Section 9.11 hereof, Purchaser shall provide Seller and its authorized representative with a copy of such completed Tax
Return and a statement (with which Purchaser will make available supporting schedules and information) certifying the amount of Tax shown on such Tax Return that is allocable to Seller pursuant to Section 9.11 at least 20 days prior to the due date
(including any extension thereof) for filing of such Tax Return. Seller and Purchaser agree to consult and to attempt in good faith to resolve any issues arising as a result of the review of such Tax Return and statement by Seller or its authorized
representative. In preparing Tax Returns pursuant to this Section 9.14(b), Purchaser shall not make any material change in any express or deemed Tax election without the prior written consent of the Seller.

Section 9.15.Tax Cooperation and Exchange of Information. Seller and Purchaser shall provide each other with
such cooperation and information as either of them reasonably may request of the other (and Purchaser shall cause AenP, TEC and Electroandes to provide such cooperation and information) in filing any Tax Return, amended Tax Return or claim for
refund, determining a liability for Taxes or a right to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes. Such cooperation and information shall include providing copies of relevant Tax Returns or
portions thereof, together with related work papers and documents relating to rulings or other determinations by taxing authorities. Seller and Purchaser shall make themselves (and their respective employees) reasonably available on a mutually
convenient basis to provide explanations of any documents or information provided under this Section 9.15. Notwithstanding anything to the contrary in Section 2.02, each of AenP, TEC, Electroandes, Seller and Purchaser shall retain all Tax Returns,
work papers and all material records or other documents in its possession (or in the possession of

---



its Affiliates) relating to Tax matters of AenP, TEC or Electroandes for any taxable period that includes the date of the Closing and for all prior taxable periods until the later of (i) the expiration of the statute of
limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions or (ii) 6 years following the due date (without extension) for such Tax Returns. After such time, before AenP, TEC, Electroandes
Seller or Purchaser shall dispose of any such documents in its possession (or in the possession of its Affiliates), the other parties hereto shall be given an opportunity, after 90 days prior written notice, to remove and retain all or any part of
such documents as any other party may select. Any information obtained under this Section 9.15 shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting an
audit or other proceeding.

Section 9.16.Tax Covenants.

(a)      Neither Purchaser nor any Affiliate of Purchaser shall take, or cause or permit AenP, TEC or Electroandes to take, any action or omit to take any action which reasonably could be expected to
increase Sellers or any of its Affiliates liability for Taxes, except to the extent required by a final determination by the relevant Governmental or Regulatory Authority.

(b)Neither Purchaser nor any Affiliate of Purchaser shall amend, refile or otherwise modify, or cause or permit AenP, TEC or Electroandes to
amend, refile or otherwise modify, any Tax election or Tax Return with respect to any taxable period (or portion of any taxable period) ending on or before the date of the Closing without the prior written consent of Seller, except to the extent
required by a final determination by the relevant Governmental or Regulatory Authority.

Section 9.17.Tax Treatment.

(a)      For Tax purposes, the parties agree to treat all payments made under this Article IX, under any other indemnity provisions contained in this Agreement, and for breaches of representations,
warranties, covenants or agreements as adjustments to the Purchase Price.

(b)Notwithstanding any provision in this Agreement to the contrary, the covenantsand agreements of
the parties hereto contained in this Article IX concerning Taxes shall survive the Closing and shall remain in full force until the expiration of the applicable statutes of limitations for the Taxes in question (taking into account any extensions or
waivers thereof), and, following the Closing, none of Purchaser, Electroandes, TEC, AenP or any of their Affiliates shall be permitted to (i) waive any protection afforded by any statute of limitations applicable to TEC, AenP or Electroandes or (ii)
grant, consent or acquiesce to any extension for any Governmental or Regulatory Authority to commence, proceed with, or appeal any Action or Proceeding in any of the foregoing cases without the prior written consent of Seller.

Section 9.18.Other Sources. Payments by Seller under this Article IX shall be limited to the amount of any
liability or damage that remains after deducting therefrom any indemnity, contribution or other similar payment recoverable by Purchaser, AenP, TEC or Electroandes from any third party with respect thereto.

Section 11.08.Necessary Funds; Purchaser Parent Guaranty.

(a)Purchaser Parent and Purchaser shall deliver to Seller, in accordance with the terms of the Side Letter, evidence satisfactory to Seller
that the Necessary Funds are available in the deposit accounts maintained by Purchaser Parent and its wholly owned subsidiaries. Purchaser Parent shall not, and shall not permit any other Person to, (i) withdraw, dividend, transfer, remove or
otherwise make unavailable all or any portion of the Necessary Funds from such accounts at any time prior to the Closing, or (ii) prior to the Closing, invest any of the Necessary Funds, other than in money market accounts, certificates of deposit,
bank repurchase agreements or bankers acceptances of, or demand deposits with, commercial banks with capital exceeding $1 billion or in commercial paper obligations rated A-1 or P-1 or better by Moodys Investors Service, Inc. or
Standard & Poors Corporation, respectively;provided,however, that Purchaser Parent shall make the Necessary Funds
available to Purchaser as necessary for Purchaser to pay the Purchase Price and all other amounts payable pursuant to this Agreement in accordance with the terms and conditions hereof or otherwise necessary to consummate all the transactions
contemplated hereby.

(b)Purchaser Parent unconditionally guarantees the performance when due by Purchaser of all of Purchasers obligations under this
Agreement. To the extent permitted by applicable Law of any Governmental or Regulatory Authority, Purchaser Parent hereby waives all defenses of a surety or guarantor to which it may be entitled. Purchaser Parent hereby waives notice of all of
Purchasers obligations and the acceptance of this guaranty by Seller. Purchaser Parent hereby waives protest, presentment, demand for payment, notice of default or non-payment and notice of dishonor. This shall be a continuing guaranty and
Seller shall not be obliged to exhaust its recourse against Purchaser or any guaranty or security that it may hold before being entitled to performance from Purchaser Parent of the obligations hereby guaranteed. This is a guaranty of payment and not
merely collection. This guaranty is irrevocable. Purchaser Parent further agrees that in the event any payment made by Purchaser under this Agreement in respect of any obligation of Purchaser hereunder is recovered from, or repaid by, Seller, in
whole or in part in any bankruptcy, insolvency, or similar proceeding instituted by or against Purchaser, this guaranty shall continue to be fully applicable to such obligation or be reinstated to the same extent as though the payment so recovered
or repaid had never been originally made on such obligation. Purchaser Parent agrees that it will not exercise any rights of subrogation that it may acquire due to its payment of an obligation of Purchaser unless and until Seller shall have been
paid in full hereunder. In the event that Purchaser Parent shall receive any payment on account of such rights of subrogation while any portion of the obligations guaranteed hereby remains outstanding, Purchaser Parent agrees to pay all such amounts
so received to Seller to be applied to the payment of the obligations payable hereunder. Any action to enforce this guaranty must be bought in the courts referred to in the first sentence of Section 11.14 and all the provisions of Sections 11.13,
11.14, and 11.15 shall apply to this guaranty. Purchaser Parent hereby represents

enter into the guaranty set forth in this Agreement and to carry out its obligations under this guaranty and (ii) the guaranty contained in this Agreement has been duly executed and delivered by Purchaser Parent, and (assuming due authorization,
execution and delivery by Seller) this guaranty constitutes a legal, valid and binding obligation of Purchaser Parent enforceable against Purchaser Parent in accordance with its terms, subject to the effect of any applicable bankruptcy,
reorganization, insolvency, moratorium or similar laws affecting creditors rights generally. The provisions of this Section 11.08 shall not subject Purchaser Parent to any greater liability than that for which Purchaser would have been liable,
and Purchaser Parent shall be entitled to rely upon any right of set off, counterclaim or other equitable claim under this Agreement on which Purchaser would have been entitled to rely. All references to Purchaser in this Section 11.08(b) are deemed
to be references to any permitted assignee of Purchaser. The provisions of this Section 11.08(b) shall terminate upon any termination of this Agreement.

pay all such amounts so received to Purchaser to be applied to the payment of the obligations payable hereunder. Any action to enforce this guaranty must be bought in the courts referred to in the first sentence of Section 11.14 and all the
provisions of Sections 11.13, 11.14, and 11.15 shall apply to this guaranty. Seller Parent hereby represents and warrants that (i) it is duly organized and validly existing under the Laws of the Governmental or Regulatory Authorities of its
