The parties agree to continue its discussion relative to any extension, pricing or terms of that certain Supply and Purchase Agreement, dated October 17, 2005.

2. Amendments.

(a) Section 1(b) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(b) Tooling and Equipment. Simultaneously with the execution of this Agreement, Sensata shall pay to EMS by wire transfer of immediately available funds to an account designated by EMS $1,875,000, which amount represents payment in full of the tooling and equipment of EMS’ ECS Division as detailed on Schedule 1(b) hereto (EMS shall deliver title to such tooling and equipment to Sensata as of the date hereof, free and clear of all liens, claims and encumbrances of any type). EMS may remove any tooling or equipment not listed on Schedule 1(b) from the ECS Division facility with the prior

2

written consent of Sensata (not to be unreasonably withheld). EMS shall have no liability for further production of ECS Products that may require use of any tooling or equipment removed by Sensata prior to the termination of this Agreement.

(i) Abandoned Tooling and Equipment. Sensata has notified EMS in writing on Schedule 1(d) of the Third Amendment to Transition Production Agreement, all of the tooling and equipment that it has abandoned in place, and has transferred title to such equipment and tooling to EMS free and clear of any liens created by Sensata. Any tooling and equipment that remains at EMS’ facility ten (10) days after the termination of this Agreement in which Sensata has not provided EMS with notice of transfer of title to Umicore shall be deemed abandoned for purposes of this Section. At such time, Sensata shall automatically transfer title to such abandoned items to EMS free and clear of any liens created by Sensata, and EMS shall dispose of such tooling and equipment at its cost and expense.

(ii) Retain and Removed Tooling and Equipment. Sensata shall remove all tooling and equipment that is identified as “Retain and Remove” on Schedule 1(d) of the Third Amendment to the Transition Production Agreement from the ECS Division facility no later than ten (10) business days after the termination of this Agreement. Sensata shall bear all costs associated with removing any such tooling or equipment, including costs associated with restoring or repairing the building to its condition prior to such removal as a result of the removal of such tooling or equipment (such restoring and repairing to be completed within ten (10) business days of the removal of such tooling or equipment). EMS shall grant Sensata reasonable access to the ECS Division facility to remove such tooling and equipment. If for any reason, EMS and Umicore do not enter into a sublease agreement, all tooling and equipment listed on Schedule 1(d) of the Third Amendment to Transition Production Agreement that was previously identified as “Retain” shall be treated as “Retain and Remove” and subject to Sensata’s obligations for removal of such tooling and equipment pursuant to this Section. Any tooling and equipment that has been identified as “Retain and Remove” in this Section that remains at EMS’ facility ten (10) business days after the termination of this Agreement shall be deemed abandoned. At such time, Sensata shall automatically transfer title to such abandoned items to EMS free and clear of any liens created by Sensata, and EMS shall dispose of such tooling and equipment at its cost and expense.

(iii) Retained Tooling and Equipment. The tooling and equipment marked “Retain” on Schedule 1(d) of the Third Amendment to Transition Production Agreement shall be transferred from Sensata to Umicore and thus remain at the ECS Division facility after termination of this Agreement. Sensata shall provide written notice to EMS when title to such tooling and equipment has transferred to Umicore (which shall include evidence of such assignment). Upon receipt of such notice, EMS shall not be responsible for any costs or repairs associated with moving any tooling and equipment transferred to Umicore.”

(b) Section 2. of the Original TPA is hereby amended by deleting such Section in its entirety and replacing such provision with the following:

“Terms and Conditions of Sale; Payment. EMS agrees to manufacture electrical contacts systems (the “ECS Products”) for Sensata in such amounts as may be specified by Sensata from time to time (such amounts, when combined with amounts (if any) then manufactured for other customers of the business as contemplated by Section 12 hereof, shall not to exceed 100% of EMS’ fixed asset capacity for ECS Products as of the date hereof, such capacity set forth on Schedule 2 hereof). Any such ECS Products shall be manufactured for Sensata in accordance with the specifications requested and provided by Sensata from time-to-time. All sales of ECS Products made by EMS to Sensata shall be on such terms and conditions of sale that are consistent with the past practice of the parties; provided, however, that (a) EMS shall indicate on each invoice for ECS Products that amount of such invoice to be allocated (and paid) to Umicore/Sensata (the amount allocated to be paid to Umicore/Sensata in such invoice, the “Silver Portion”) and the amount of such invoice to be allocated (and paid) to EMS (the “EMS Portion”), and (b) Sensata shall pay (by wire transfer of immediately available funds) directly to Umicore/Sensata the Silver Portion of the purchase price for such ECS Products (as set forth on the applicable invoice) on the date of shipment of such ECS Products to Sensata and shall pay directly to EMS (by wire transfer of immediately available funds) the EMS Portion of the purchase price for such ECS Products (as set forth on the applicable invoice) on the date of shipment of such ECS Products to Sensata. EMS will provide Umicore/Sensata with a copy of each invoice for such ECS Products upon issuance. Sensata will provide EMS with a copy of the wire transfer confirmation of each payment of the Silver Portion and EMS Portion. EMS acknowledges and agrees that payment by Sensata of the Silver Portion of the purchase price and the EMS Portion of the purchase price (each as contemplated above and set forth in the applicable invoice) shall constitute payment in full of the aggregate purchase price payable by Sensata for such ECS Products. During the term of this Agreement, Sensata shall issue (at a minimum) each Thursday of each week, purchase orders for the purchase and sale of all finished ECS Products produced on behalf of Sensata pursuant to its specifications (that are not subject to a previous purchase order) containing a shipment date no longer than five (5) calendar days from the date of the purchase order. To the extent that there is any inconsistency between the terms of this Agreement and the “past practices” of the parties (as contemplated by this Section 2), then the terms of this Agreement shall control. IN NO EVENT SHALL EMS HAVE ANY LIABILITY TO SENSATA ARISING FROM EMS’ FAILURE TO FULFILL ITS OBLIGATIONS TO MANUFACTURE ECS PRODUCTS FOR SENSATA PURSUANT TO THIS SECTION 2 IN EXCESS OF THE AMOUNTS PAID BY SENSATA FOR SUCH ECS PRODUCTS (AND IN NO EVENT WILL EMS BE LIABLE TO SENSATA FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY NATURE, WHETHER BASED IN CONTRACT, IN TORT OR OTHERWISE, THAT ARISE FROM EMS’ FAILURE TO FULFILL ITS OBLIGATIONS TO MANUFACTURE ECS PRODUCTS FOR SENSATA PURSUANT TO THIS SECTION 2, INCLUDING BUT NOT LIMITED TO LOSS OF USE OF THE ECS PRODUCTS AND LOSS OF PROFITS). EMS shall have no liability or be in breach of this Section 2 for any failure or delay in performance due to strikes, lockouts, concerted acts of workmen, fires, explosions, floods or other natural catastrophes, civil disturbance or riots, armed conflict (whether declared or undeclared),

4

terrorist acts, acts of God, compliance with acts of government and government regulations, embargoes or any other similar cause which is beyond the reasonable control of EMS. For the avoidance of doubt, Sensata hereby agrees that EMS shall not be required to remit the Silver Portion of any purchase price of ECS Products sold to Checon until such time that EMS receives payment in full from Checon for such ECS Products”

(c) Section 3(a)(ii) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(ii) the last day of the calendar month following the month of delivery of written notice of termination sent by Sensata to EMS at any time on or following the thirtieth (30^th) calendar day after the date hereof;”

(d) Section 3(a)(iii) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(iii) May 31, 2010;”

(e) Section 3(a)(v) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(v) immediately upon (i) the effective date specified in a written notice delivered by Sensata to EMS following the final determination of EMS’ breach of any of its obligations set forth in Schedule 10, (ii) the effective date specified in a written notice delivered by EMS to Sensata after the final determination of Sensata’s breach of any of its obligations set forth in Section 4 (Loss Payment), Section 5 (Working Capital Prepayment) (such final determination to be made in the manner set forth in Section 4 or Section 5, respectively), or (iii) the effective date specified in a written notice delivered by EMS to Sensata following Sensata’s failure to pay EMS the invoiced amount for any ECS Products pursuant to Section 2 hereof.”

(f) Section 3(b) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(b) Upon the termination of this Agreement (including after expiration of any applicable notice provision contemplated by Section 3(a)), Sensata shall immediately purchase from EMS and EMS shall sell to Sensata all Inventory of the ECS Division (to the extent meeting Sensata’s specifications and produced by EMS or purchased by EMS for Sensata), at a purchase price equal to the then current net carrying cost of any raw materials and work in process, as stated in EMS’ books and records of accounting, (prepared in accordance with past practice) and the historical sale price paid by Sensata to EMS for any finished goods; provided, however, that Sensata may (in its sole discretion) but shall not be obligated to purchase such Inventory in the event that EMS has breached this Agreement in any material respect. For purposes of this Agreement “Inventory” shall include all: (i) raw materials (including any raw materials not yet delivered to EMS, but that have been ordered by EMS in connection with orders placed by Sensata for ECS

5

Products); (ii) work in process; and (iii) finished goods, wherever located. Subject to the foregoing, EMS shall deliver the Inventory within ten (10) days after the termination of this Agreement or within ten (10) days after the receipt of all raw materials ordered by EMS in connection any previously accepted order for ECS Products from Sensata, provided that any orders for raw materials purchased after the effective date of the Third Amendment to Transition Production Agreement have been approved by Sensata prior to EMS placing such orders with their suppliers, whichever is later, such delivery to be made at Sensata’s expense (such expenses to be approved in advance by Sensata in writing) to a location specified in writing by Sensata, and upon delivery, Sensata shall pay the amounts specified herein. For the avoidance of doubt, EMS shall have the right to apply any amounts owed to it by Sensata under this Section against any amounts owed to Sensata pursuant to the Working Capital Prepayment (as defined in Section 5).”

(g) Section 3(c) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“During the term of this Agreement, Sensata hereby acknowledges and agrees to use its reasonable efforts to cause Umicore to sublease a portion of the ECS Division facility from EMS, and to accommodate EMS and Umicore in preparing the ECS Division facility to be leased to Umicore upon termination of this Agreement.”

(h) Section 4(a) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

“(a) Within five (5) days of the end of each calendar month during the term of this Agreement or in the event of termination of this Agreement within thirty (30) days after the termination, EMS shall prepare and deliver to Sensata a profit and loss statement for the immediately preceding calendar month (or partial month) with respect to the ECS Division prepared in accordance with the accounting principles and allocation ratios set forth on Schedule 4 attached hereto (each, a “P&L Statement”).”

(i) Section 4(e) of the Original TPA is hereby amended by deleting such sub-section in its entirety and replacing such provision with the following:

6

(j) Section 5 of the Original TPA is hereby amended by deleting such provision in its entirety and replacing such provision with the following:

“5. Working Capital Prepayment. The parties hereto acknowledge and agree that during the term of this Agreement, EMS shall not be required to commit any Net Working Capital (as defined below) to the ECS Division. For purposes of this Agreement, “Net Working Capital” means an amount equal to the book value of Inventory of the ECS Division minus any pre-existing non-Sensata inventory prior to the effective date of the Third Amendment to Transition Production. Net Working Capital and all components thereof shall be determined with respect to the entire ECS Division (i.e. for all customers of the ECS Division consistent with Section 12). During the term of this Agreement Sensata shall prepay an amount to EMS equal to the amount of book value of Inventory of the ECS Division (the “Working Capital Prepayment”). The Working Capital Prepayment shall be funded and adjusted on a weekly basis. EMS shall use the Working Capital Prepayment solely in its ECS Division. Each Friday EMS shall provide Sensata with an ECS Division Net Working Capital statement setting forth EMS’ good faith determination of Net Working Capital as of the close of business (each, a “Net Working Capital Statement”). Sensata shall have a right to review any Net Working Capital Statement pursuant to its rights set forth in Section 10 (Access to ECS Division). On the Monday immediately following the Friday delivery of any Net Working Capital Statement by EMS to Sensata, the Working Capital Prepayment shall be funded or adjusted as follows: (i) to the extent that Net Working Capital is greater than the then current Working Capital Prepayment from Sensata to EMS, Sensata shall wire to EMS in immediately available funds an amount equal to the difference between the Net Working Capital and the then current Working Capital Prepayment; or (ii) to the extent that the Net Working Capital is less than the then current Working Capital Prepayment from Sensata to EMS, EMS shall wire to Sensata in immediately available funds an amount equal to the difference between the Net Working Capital and the then current Working Capital Prepayment such that Net Working Capital shall equal the Working Capital Prepayment. The Working Capital Prepayment shall be unsecured, shall not bear any interest, and shall be subordinated to any funded indebtedness of EMS, including any secured loans from Contrarian Financial Service Company, LLC or Wickeder US Beteiligungs GmbH.”

(k) Section 14 of the Original TPA is hereby amended by deleting such provision in its entirety and replacing such provision with the following:

“14. Set-Off. (a) Except in the event that Sensata breaches its obligation to pay the Silver Portion of any invoice to Umicore/Sensata, if Umicore/Sensata shall have drawn upon that certain letter of credit issued by The Bank of New York Mellon (the “Letter of Credit”) (which, pursuant to the terms therein, provides security for the Delivery of Precious Metals (as defined in the Consignment Agreement) for the production of ECS Products under that certain Consignment Agreement between Umicore/Sensata and EMS, dated as of February 21, 2008 (as amended, the “Consignment Agreement”)), or (b) EMS breaches any of its obligation to Sensata hereunder, in the case of either clause (a) or (b) above, then Sensata is hereby authorized, subject to Umicore/Sensata’s right to be paid in full with respect to all of EMS’ Obligations (as defined in the Consignment Agreement) to Umicore/Sensata under the Consignment Agreement (other than contingent indemnification obligations for which no claim has been asserted), at any time and from

7

time to time after Sensata exercises its rights under the Consignment Agreement and only to the extent that Sensata suffers a deficiency between the amount drawn upon the Letter of Credit and the amount recovered by Sensata after the exercise of its remedies under the Consignment Agreement, to the fullest extent permitted by law, to setoff and apply any and all deposits related to the ECS Division (including, without limitation, any pre-payments of ECS Products constituting finished goods inventory to be purchased by Sensata from EMS’ ECS Division) and/or other amounts payable by Sensata to EMS pursuant to the terms of this Agreement against any and all of such deficiency. In the event that Sensata breaches any of its obligation to EMS hereunder, then EMS is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to setoff and apply any and all deposits (including, without limitation, any pre-payments of ECS Products constituting finished goods inventory to be purchased by Sensata from EMS’ ECS Division), the Working Capital Prepayment, and/or other amounts payable by EMS to Sensata pursuant to the terms of this Agreement against any and all of the amounts owed by Sensata to EMS, including, but not limited to Sensata’s obligations to purchaser Inventory as set forth in Section 3(b). For the avoidance of doubt, the parties acknowledge and agree that their respective set-off rights set forth in this Section 14 are solely limited to deposits and rights associated with the ECS Division. The parties hereby affirmatively waive any and all rights to exercise any setoff, counterclaim or deduction with respect to any amounts arising under or in respect of this Agreement against any other amounts owing to or from each other under matters other than under this Agreement, including any obligations, deposits, or rights related to EMS’ bi-metal division.”

(l) Schedule 10 of the Original TPA is hereby amended by deleting Item 7 in its entirety and replacing it with the following:

“7. EMS will not issue a purchase order, purchase order release, or make commitments thereof for inventory, expenses, services, labor, repairs or capital without Sensata’s prior approval.”

3. Remaining Terms Unaffected. Except for the amendments to the Original TPA set forth herein, all other provisions of the Original TPA shall remain in full force and effect and are incorporated herein as if fully set forth herein.

Kevin Folan

Chief Financial Officer

EMS Engineered Materials Solutions, LLC

39 Perry Avenue

Attleboro, MA 02703

Dear Mr. Folan:

The purpose of this letter is to document the agreement between EMS Engineered Materials Solutions, LLC (“EMS”) and Sensata Technologies, Inc. (“Sensata”) regarding electricity service and maintenance provided to the Attleboro Corporate Campus Association (the “ACCA”). ACCA is responsible for maintaining and paying the ACC Account with National Grid (“National Grid”) for electricity service and maintenance provided to the former Texas Instruments Attleboro Campus.

EMS and Sensata had previously entered into an agreement on April 17, 2008 regarding the allocation of the monthly electricity bill between the two parties. As you are aware, Pepco has opted to terminate its agreement with EMS and Sensata to provide energy services. Consequently, EMS and Sensata have sought the services of other energy providers. A contract (the “ConEdison Agreement”) has been signed by EMS and Sensata with ConEdison Solutions (“ConEdison”) regarding energy services for the ACCA for the period of the December 2009 billing cycle to the December 2010 billing cycle, pursuant to which EMS and Sensata have agreed to be jointly and severally liable to ConEdison for all their respective obligations under the ConEdison Agreement.

EMS agrees to continue to remit approximately 60% of the fees (subject to actual meter readings for each month) due to National Grid for transmission and distribution services and approximately 60% of the fees (subject to actual meter readings for each month) due to ConEdison for energy charges applicable to the ACCA. In addition, EMS has agreed that it is responsible for the energy fees applicable to Building 2 (currently occupied by Bristol Community College), Buildings 3 and 4 at 39 Perry Street (currently occupied by EMS), Building 5 (currently occupied by Linde Gas), Building 10 (currently occupied by Vertex), and Unit A of Building 11 (currently occupied by New Age). EMS, in its own discretion, may invoice and collect any fees it pays on behalf of BCC, Linde Gas, Vertex and New Age.

Similarly, Sensata agrees to continue to remit approximately 40% of the fees (subject to actual meter readings for each month) due to National Grid for transmission and distribution services and 40% of the fees (subject to actual meter readings for each month) due to ConEdison for energy charges applicable to the ACCA. In addition, Sensata has agreed that it is responsible for the energy fees applicable to the Business Center at 529 Pleasant Street and Building 12 at 533 Pleasant Street (both currently occupied by Sensata), Building 1 (currently owned by Preferred), Buildings 20 and 21 (currently owned by Ronald Pratt Co.) and Unit B of Building 11 (currently owned by New Stream). Sensata, in its own discretion, may invoice and collect fees it pays on behalf of Preferred, Ronald Pratt Co. and New Stream.

Sensata hereby agrees to indemnify, defend and save harmless EMS from and against liabilities, losses or claims of any kind or nature incurred by EMS arising out of Sensata’s (i) breach of any agreement with National Grid, including Sensata’s failure to pay its approximate 40% share of energy transmission and delivery charges National Grid, or (ii) breach of the Electricity Sales Agreement with ConEdison, including Sensata’s failure to timely pay its approximate 40% share of energy charges to ConEdison.

EMS hereby agrees to indemnify, defend and save harmless Sensata from and against liabilities, losses or claims of any kind or nature incurred by Sensata arising out of EMS’ (i) breach of any agreement with National Grid, including EMS’ failure to pay its approximate 60% share of energy transmission and delivery charges to National Grid, or (ii) breach of the Electricity Sales Agreement with ConEdison, including EMS’ failure to timely pay its approximate 60% share of energy charges to ConEdison

EMS and Sensata further agree that in the event of any dispute, litigation, claim or proceeding initiated against them (an “Adverse Claim”) in connection with or arising out of the transactions contemplated by the ConEdison Agreement (including, without limitation, any claims by ConEdison or National Grid), all fees, expenses and other costs associated with defending against and resolving an Adverse Claim, including, without limitation, any judgment or settlement as a result thereof (collectively, the “Claim Fees and Expenses”), shall be divided between EMS and Sensata as follows: EMS shall pay sixty percent (60%) of all such Claim Fees and Expenses, and Sensata shall pay forty percent (40%) of all such Claim Fees and Expenses. To the extent any Claim Fees and Expenses are paid for in their entirety by EMS or Sensata, as the case may be, the non-paying party shall remit its share of such Claim Fees and Expenses to the paying party promptly following the non-paying party’s receipt of a written request therefor, together with such substantiating documentation as the non-paying shall reasonably request.

In consideration of the covenants and agreements contained herein, EMS and Sensata understand, acknowledge and agree that they shall not bring any claim, action, lawsuit or legal or equitable proceeding of any kind against each other based on, encompassed in or related in any way to the ConEdison Agreement or any Adverse Claim, and further covenant and agree that they will not encourage, cooperate with or in any way participate in or facilitate such a claim, action, lawsuit or legal proceeding by any third party except as required by law or properly issued subpoena.

The parties hereby covenant and agree that neither party shall communicate directly with ConEdison or provide any notice to ConEdison with respect to the ConEdison Agreement (including any notice of termination) without the written consent of the other party.

This letter agreement shall remain in effect until the earlier of: (i) the mutual agreement in writing by the parties to terminate this letter agreement; or (ii) upon termination of the Electricity Sales Agreement, between EMS and Sensata on the one hand, and ConEdison on the other. Any amendment to the terms of this letter agreement must be in writing signed by the parties. This letter agreement will be governed by and construed in accordance with the laws of Massachusetts. The indemnification obligations set forth herein will survive the termination of this letter agreement.

If EMS is in agreement with the foregoing, please sign and return the enclosed copy of this letter to my attention. We appreciate your cooperation and assistance in this matter.

The undersigned, on behalf of Engineered Materials Solutions, agrees with the foregoing terms and conditions.

Contract # 139989

(LDC/TDSP Meter Reading Date for February 2010 to Meter Reading Date for February 2012)

Schedule 1(c)

February     , 2010

Mr. Jeffrey Bergman

Sensata Technologies, Inc.

529 Pleasant Street

Attleboro, MA 02703

Dear Mr. Bergman:

Reference is made to (i) that certain Letter Agreement (the “2008 Letter Agreement”), dated as of April 17, 2008, between Sensata Technologies, Inc. (“Sensata”) and EMS Engineered Materials Solutions, LLC (“EMS”), and (ii) that certain Master Electric Sales Agreement (the “Master Electric Agreement”), effective as of May 1, 2008, among Sensata, EMS and Pepco Energy Services, Inc. (“Pepco”).

Pursuant to the Master Electric Agreement, EMS and Sensata are jointly and severally liable to Pepco for the costs associated with Pepco’s provision of electric energy to the former Texas Instruments Attleboro Campus using the transmission system of National Grid (“National Grid”). In addition, under the terms of the Letter Agreement, EMS agreed to be responsible for approximately 60% of the fees subject to actual meter readings due to Pepco and National Grid in connection with transmission and distribution services and energy charges, and Sensata agreed to be responsible for approximately 40% of the fees subject to actual meter readings due to Pepco and National Grid in connection with transmission and distribution services and energy charges.

As you are aware, Pepco has sent correspondence to EMS and Sensata alleging a default under the Master Electric Agreement and claiming damages for material change in usage of up to approximately $617,820 (the “Pepco Claim”). The purpose of this letter is to affirm EMS’ and Sensata’s mutual interest in and commitment to jointly defending themselves against the Pepco Claim, and to document the agreement between EMS and Sensata regarding the fees, expenses and other costs that may be incurred in connection therewith.

As you are also aware, Pepco drew down on both EMS’ $700,000 letter of credit and Sensata’s $500,000 letter of credit. Pepco has applied a portion of those draws to electricity usage fees for the months of November and December 2009 and a portion of those draws to offset the Pepco Claim.

In the interest of settling this and other issues with EMS, EMS and Sensata hereby agree that any and all legal and other fees, expenses and other costs associated with defending against and resolving the Pepco Claim, including, without limitation, any judgment or settlement as a result thereof (collectively, the “Fees”), shall be divided between EMS and Sensata as follows: EMS shall pay seventy percent (70%) of all such Fees, and Sensata shall pay thirty percent (30%) of all such Fees. For the purpose of clarity, Nixon Peabody has been retained to jointly represent both Sensata and EMS in connection with this matter. The parties agree that Nixon Peabody’s legal fees associated with this matter shall be considered part of the Fee; provided, however, if the parties are unable to agree on a common legal approach, each party shall have the right to engage separate counsel, and will be responsible for paying for legal fees for such separate counsel. To the extent any Fee is paid for in its entirety by EMS or Sensata, as the case may be, the non-paying party shall remit its share of such Fee to the paying party promptly following the non-paying party’s receipt of a written request therefor, together with such substantiating documentation as the non-paying party shall reasonably request.

In recognition of EMS’ and Sensata’s mutual interest in defending against the Pepco Claim, EMS and Sensata understand, acknowledge and agree that they shall not bring any claim, action, lawsuit or legal or equitable proceeding of any kind against each other based on, encompassed in or related in any way to the Pepco Claim, the 2008 Letter Agreement or the Master Electric Agreement, and further covenant and agree that they will not encourage, cooperate with or in any way participate in or facilitate such a claim, action, lawsuit or legal proceeding by any third party except as required by law or properly issued subpoena.

Unless otherwise terminated by the material breach of EMS or Sensata, this letter agreement shall remain in effect until the mutual agreement in writing by EMS and Sensata to terminate it. Any amendment to the terms of this letter agreement must be in writing signed by EMS and Sensata. This letter agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to its conflict of law principles. This letter agreement contains the entire understanding among the parties hereto with respect to the subject matter hereof, and supersedes any and all other prior agreements, understandings, discussions, negotiations whether written or oral among the parties, including but not limited to the 2008 Letter Agreement.

If the terms of this letter agreement are acceptable, please sign and date both enclosed copies of this letter agreement and return one fully executed copy to the undersigned.
