 Section 1.3 Shared Facilities. 
 (a) The Land does not include the land upon which the Remote Facilities are located; however, as provided in Section 1.1(d),
those Remote Facilities are subject to the lien and security interest of this Deed of Trust and are accessible to the owner of Unit 1 and 2 and the Beneficiary pursuant to the Easement Agreement. By its acceptance of this Deed of Trust, Beneficiary
acknowledges that, in connection with the development, construction and operation of Unit 3, Generation Development (or its Affiliates) may require the use and enjoyment on a shared basis with the owner of Units 1 and 2 of (i) certain
designated Remote Facilities (“Shared Remote Facilities”) and (ii) certain other designated facilities that are located on the Land, but which shall not include the facilities set forth on Schedule 1A (“Excluded Unit 1
and 2 Plant Island Facilities”), but may include the facilities set forth on Schedule 1B and such additional facilities located on the Land that are reasonably necessary or advisable to be shared in connection with the development or
operation of Unit 3 (the “Unit 1 and 2 Plant Island Shared Facilities”), as set forth in this Section 1.3. By acceptance of this Deed of Trust, Beneficiary acknowledges and agrees that, subject to the terms of this
Section 1.3, Grantor and Generation Development (or its Affiliates) may enter into one or more agreements (collectively, the “Shared Facilities Agreements”) that allow Generation Development (or its Affiliates) to use
and enjoy such designated Shared Remote Facilities and/or Unit 1 and 2 Plant Island Shared Facilities (collectively referred to as “Shared Facilities”) together with the owner of Unit 1 and 2. 
 (b) In furtherance of the foregoing, Beneficiary acknowledges and agrees that the lien and security interest of this Deed of Trust as to
such Shared Remote Facilities which are to be or shall be used by Generation Development (or its Affiliates) in connection with the development, construction or operation of Unit 3 shall be released upon request by Grantor; provided, however,
(i) no such release shall become effective unless and until a Shared Facilities Agreement has been entered into with respect thereto; (ii) Grantor has provided Beneficiary with written notice of, and a copy of, such proposed Shared
Facilities Agreement not less than twenty (20) calendar days prior to the proposed effective date of such agreement; and (iii) Beneficiary (acting at the direction of the Required Creditors) has consented in writing to such Shared
Facilities Agreement, which consent, so long as no Trigger Event has occurred and is continuing, shall not be unreasonably withheld, conditioned or delayed. Beneficiary shall not be deemed to have unreasonably withheld its consent if the proposed
Shared Facilities Agreement contains terms that are inconsistent with the Commercially Reasonable Terms set forth in Section 1.3(d). Beneficiary shall have no obligation to release any lien granted by this Deed of Trust or consent to a
Shared Facilities Agreement as set forth in this Section 1.3(b) if a Trigger Event has occurred and is continuing. 
 (c) Beneficiary acknowledges and agrees that Grantor and Generation Development (or its Affiliates) may enter into one or more Shared Facilities Agreements with respect to designated Unit 1 and 2 Plant Island Shared Facilities (other than
Excluded Unit 1 and 2 Plant Island Facilities); provided that (i) Grantor has furnished Beneficiary with written notice of, and a copy of, such proposed Shared Facilities Agreement not less than twenty 
  

			
	 DEED OF TRUST
	  	PAGE 6

 (20) calendar days prior to the proposed effective date of such agreement; and (ii) Beneficiary has
consented in writing to such Shared Facilities Agreement, which consent, so long as no Trigger Event has occurred and is continuing, shall not be unreasonably withheld, conditioned or delayed. Beneficiary shall not be deemed to have unreasonably
withheld its consent if the proposed Shared Facilities Agreement pertaining to such Unit 1 and 2 Plant Island Shared Facilities contains terms that are inconsistent with the Commercially Reasonable Terms set forth in Section 1.3(d).
Grantor acknowledges and agrees that Shared Facilities Agreements pertaining to such Unit 1 and 2 Plant Island Shared Facilities shall be on Commercially Reasonable Terms, to the extent such terms are applicable. Grantor and Beneficiary agree that
Beneficiary will not be required to release its lien on any Unit 1 and 2 Plant Island Shared Facilities; provided, however, that Beneficiary acknowledges and agrees that its lien on any such Unit 1 and 2 Plant Island Shared Facility will be
subject and subordinate to the terms and conditions of the related Shared Facilities Agreement and will, more specifically, be subject to any easement granted to Generation Development in favor of Unit 3 in the related Shared Facilities Agreement.
Beneficiary shall have no obligation to consent to a Shared Facilities Agreement pertaining to facilities at Units 1 and 2 or subordinate its lien to any Shared Facilities Agreement easement as set forth in this Section 1.3(c) if a
Trigger Event has occurred and is continuing. 
 (d) For purposes of any Shared Facilities Agreement applicable to Remote
Shared Facilities and Unit 1 and 2 Plant Island Shared Facilities, “Commercially Reasonable Terms” means that such agreement: 
  

	 	(i)	contains customary perpetual, non-exclusive reciprocal (if appropriate) easements appurtenant for access, ingress, egress, utilities, control systems and plant operations by the
owner of Units 1 and 2 and the owner of Unit 3; provided, however, that no such easement need be granted for the benefit of the owner of Units 1 and 2 if such grant would be redundant of easements existing under the Easement Agreement with respect
to the Remote Facility; 

  

	 	(ii)	provides that, from and after the effective date of the Shared Facilities Agreement, Beneficiary, on the one hand, and the holders of the First Lien Credit Facilities and Second
Lien Credit Facilities, on the other hand, shall each have, or be entitled to have, a lien on the Shared Facilities Agreement and such easements; 

  

	 	(iii)	identifies the holders of the First Lien Credit Facilities and Second Lien Credit Facilities (or their respective collateral agents) as permitted successor obligors of Generation
Development (or the owner of Unit 3, if different), and as permitted successor beneficiaries, under such Shared Facilities Agreement and obligates the owner of the Land to execute a consent to assignment to such holders or collateral agents in
customary form; 

  

			
	 DEED OF TRUST
	  	PAGE 7

	 	(iv)	identifies Beneficiary as a permitted successor obligor of Grantor, and as a permitted successor beneficiary, under such Shared Facilities Agreement and obligates the owner of the
land upon which Remote Facilities are currently located to execute a consent to assignment to such holders or collateral agents in customary form; 

  

	 	(v)	provides that any Shared Facility may not be sold, scrapped or disposed of except for (A) a Shared Facility that is obsolete, damaged or not used or useful in the operation of
Units 1 and 2 so long as the fair market value of all such Shared Facilities does not exceed, in the aggregate, in the case of Shared Remote Facilities, twenty million dollars ($20,000,000), and in the case of Unit 1 and 2 Plant Island Shared
Facilities, ten million dollars ($10,000,000), over any rolling twelve-month period; (B) a Shared Facility that is disposed of in the ordinary course of business in accordance with prudent operating practices for power generation facilities, so
long as the fair market value of all such Shared Facilities does not exceed, in the aggregate, in the case of Shared Remote Facilities, twenty million dollars ($20,000,000), and in the case of Unit 1 and 2 Plant Island Shared Facilities, ten million
dollars ($10,000,000), over any rolling twelve-month period; (C) Shared Facilities that are replaced by substantially equivalent Shared Facilities as reasonably determined by Grantor acting in good faith; or (D) Shared Facilities
with respect to which the Beneficiary has consented to such release (which, provided that no Trigger Event has occurred and is continuing, shall not be unreasonably withheld, conditioned or delayed); 

  

	 	(vi)	with respect to Unit 1 and 2 Plant Island Shared Facilities, subject to the provisions of Section 1.3(d)(viii), provides that the Unit 3 owner’s use of such Unit 1
and 2 Plant Island Shared Facilities shall not otherwise restrict, impair, limit, interfere with or hinder Units 1 and 2 from operating and performing (including, but not limited to, with respect to their capacity and output) in a manner consistent,
in all substantive respects, with the historical performance of such units; 

  

	 	(vii)	does not materially increase the net cost of operating Units 1 and 2 in the ordinary course of such operations (as compared to the net cost of operating Units 1 and 2 in the
ordinary course of such operations prior to the effectiveness of the Shared Facilities Agreement) and fairly and reasonably allocates the costs to operate and maintain the Shared Facilities between the owners of Units 1 and 2 and Unit 3,
respectively; 

  

	 	(viii)	generally provides for a pro-rata sharing of any decrease in the capacity or output of the Shared Facilities and does not otherwise give preferences to Unit 3 to the detriment of
Units 1 and 2, except those preferences that are pursuant to a reasonable objective metric fairly and consistently applied; and 

  

			
	 DEED OF TRUST
	  	PAGE 8

	 	(ix)	has a perpetual term and may not be terminated or materially amended or modified without the prior written consent of Beneficiary (which consent may not be unreasonably withheld,
conditioned or delayed). 

 (e) Beneficiary (acting at the direction of the Required Creditors), by its
acceptance of this Deed of Trust, covenants and agrees to cooperate in good faith from time to time, upon request by Grantor, (i) to identify the specific Remote Facilities and facilities of Units 1 and 2 (excluding, however, Excluded Unit 1
and 2 Plant Facilities) which will become Shared Facilities, (ii) to allocate the correlative rights and duties of the owners of Units 1 and 2 and the owner of Unit 3 as to such Shared Facilities, and (iii) to document the release thereof
from the lien and security interest of this Deed of Trust, as set forth in this Section 1.3 and Section 7.14.

to, interest in or claim upon the Collateral attaching or accruing subsequent to the recording of this Deed of Trust, except as provided in Section 1.3, and shall be secured by this Deed of Trust, to the extent permitted by law.

 (a) Financial Matters. Grantor is solvent, is not bankrupt and has no outstanding
bankruptcies, and, to Grantor’s knowledge, has no outstanding liens, suits, garnishments, bankruptcies or court actions which would render Grantor insolvent or bankrupt. There has not been filed by or, to Grantor’s knowledge, against

good right and authority to grant, bargain, sell, transfer, assign and mortgage the Real Property, Improvements, Fixtures and Equipment and Remote Facilities. Concurrently with the execution and delivery of this Deed of Trust, the Grantor, at its
expense, has obtained and delivered to the Beneficiary a loan policy or policies of title insurance issued by First American Title Insurance Company (the “Title Insurer”) in an amount and in form and substance reasonably
satisfactory to the Required Creditors and naming the Beneficiary as the insured, insuring the title to and the first mortgage lien of this Deed of Trust on the Land and Improvements and the easements and rights created pursuant to the Easement
Agreement (the “Title Policy”). The Grantor has duly paid in full all premiums and other charges due in connection with the issuance of such Title Policy. All proceeds received by and payable to the Beneficiary for any loss under
the Title Policy, or under any policy or policies of title insurance delivered to the Beneficiary in substitution therefor or replacement thereof, shall be the property of the Beneficiary and shall be applied by the Beneficiary in accordance with
the Intercreditor Agreement. 
 (c) Permitted Encumbrances. The Collateral is free and clear from all liens, security
interests and encumbrances arising by, through or under Grantor except (i) the lien and security interest evidenced hereby and the only encumbrances thereupon are title exceptions more particularly set forth in Exhibit B attached hereto
and made a part hereof, (ii) the rights of parties to Shared Facilities, as provided herein and (iii) all the Liens permitted to be incurred on the Collateral under the Intercreditor Agreement (collectively, the “Permitted
Encumbrances”). Grantor has not consented to any person conducting any operations to explore for, drill, produce or recover oil and gas reserved in the deed referred to in item “b” of Exhibit B.

	  	PAGE 10

 (f) Enforceability. This Deed of Trust constitutes the legal, valid and binding
obligations of Grantor enforceable in accordance with its terms except as such enforceability may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally and by
general principles of equity. The execution and delivery of, and performance under, this Deed of Trust are within Grantor’s powers and have been duly authorized by all requisite action and are not in contravention of the powers of
Grantor’s partnership agreement or other partnership documentation. 
 (g) Not a Foreign Person. Grantor is not a
“foreign person” within the meaning of the Internal Revenue Code of 1986, as amended (hereinafter called the “Code”), Sections 1445 and 7701 (i.e., Grantor is not a non-resident alien, foreign
corporation, foreign partnership, foreign trust or foreign estate, as those terms are defined in the Code and regulations promulgated thereunder). 
 (h) Sufficiency of Collateral. The Collateral includes every item of real or personal property that is owned by the Grantor and used by Grantor in the operation of Units 1 and 2. 
 Section 3.2 Covenants and Agreements. So long as the Secured Obligations or any part thereof remains unperformed or unpaid, Grantor covenants
and agrees with Beneficiary as follows: 
 (a) Existence. Grantor will continuously maintain its existence and its
right to do business in the State of Texas. 
 (b) Taxes on Deed of Trust. Grantor will promptly pay all income,
franchise and other taxes owing by Grantor and any stamp taxes which may be required to be paid with respect to this Deed of Trust except to the extent the same are not due and payable or are contested by Grantor in good faith. 
 (c) Maintenance of Collateral. Grantor will maintain, repair, replace and upgrade the Collateral in accordance with prudent
operating practices customary for the electric power generation industry and in a manner consistent with its historic practice (including such historic practice with respect to Grantor and its Affiliate’s portfolio of similar generation
facilities) including taking appropriate immediate action in the case of an emergency which threatens health or safety or to damage the Collateral. While recognizing that the use of the Shared Facilities will, of necessity, be subject to the terms
and conditions of Shared Facilities Agreements, neither Grantor nor any Affiliate, including Generation Development, will take any action (without the consent of the Beneficiary, acting at the direction of the Required Creditors, which consent shall
not be unreasonably withheld, conditioned or delayed, provided no Trigger Event shall have occurred and be continuing), except in connection with upgrades or additions to emissions or other environmental controls (in compliance with applicable legal
or regulatory requirements or agreements with governmental authorities or regulators and implemented in accordance with prudent 
  

			
	 DEED OF TRUST
	  	PAGE 11

 operating practices customary for the electric power generation industry) that would restrict, impair,
limit, interfere with or hinder Units 1 and 2 from operating and performing (including, but not limited to, their capacity and output) in a manner consistent, in all substantive respects, with the historical performance of such units. 
 (d) Design and Construction of Unit 3. While recognizing that the use of the Shared Facilities will, of necessity, be subject to
the terms and conditions of the Shared Facilities Agreements, without the consent of Beneficiary, acting at the direction of the Required Creditors (which consent may not be unreasonably withheld, conditioned or delayed, provided no Trigger Event
shall have occurred and be continuing), Grantor and its Affiliates, including Generation Development, will not design and construct Unit 3 in such a manner that would diminish the historic capacity or output of Units 1 and 2 except, prior to any
Trigger Event occurring and continuing, for reasonable temporary outages that occur at Units 1 and 2 in conjunction with the construction of Unit 3 which would not reasonably be expected to decrease the long term value of the Collateral; provided,
however, that should a Trigger Event occur during any such temporary outage, Grantor shall be liable to Beneficiary for any damages suffered by Beneficiary as a result of such outage following the occurrence and during the continuation of said
Trigger Event. 
 (e) Permitted Encumbrances. Grantor shall not create, incur or suffer to exist any liens on the
Collateral other than Permitted Encumbrances nor consent to any person conducting any operations to explore for, drill, produce or recover oil and gas reserved in the deed referred to in item “b” of Exhibit B. 
 (f) Condemnation. Promptly upon obtaining knowledge of the institution of any proceedings for the condemnation of the Real Property
or any portion thereof, or any other proceedings arising out of injury or damage to the Collateral, or any portion thereof, Grantor will notify Beneficiary of the pendency of such proceedings except where such proceedings could not reasonably be
expected, individually or in the aggregate, to result in a material adverse effect on Grantor. Beneficiary may participate in any such proceedings, and Grantor shall from time to time deliver to Beneficiary all instruments reasonably requested by it
to permit such participation. Grantor shall, at its expense, diligently prosecute any such proceedings, and shall consult with Beneficiary, its attorneys and experts, and cooperate with them in the carrying on or defense of any such proceedings.

 (g) Ad Valorem Taxes. Grantor will cause to be paid prior to delinquency all taxes and assessments heretofore or
hereafter levied or assessed against the Collateral except to the extent the same are not due and payable or are contested by Grantor in good faith to the extent permitted by applicable law. 
 (h) Protection and Defense of Lien. Except, in each case, to the extent that the failure to do so would not reasonably be expected,
individually or in the aggregate, to result in a material adverse effect upon the value of the Collateral or its usefulness in the operation of Units 1 and 2, if the validity or priority of this Deed of Trust or of any rights, titles, liens or
security interests created or evidenced hereby with respect to the Collateral or any part 
  

			
	 DEED OF TRUST
	  	PAGE 12

 thereof shall be endangered or questioned or shall be attacked directly or indirectly or if any legal
proceedings are instituted against Grantor with respect thereto, Grantor will give prompt written notice thereof to Beneficiary and at Grantor’s own cost and expense will diligently endeavor to cure any defect that may be developed or claimed,
and will take all commercially reasonable, necessary and proper steps for the defense of such legal proceedings, including, without limitation, the employment of counsel, the prosecution or defense of litigation and the release or discharge of all
adverse claims, and Trustee and Beneficiary, or either of them (whether or not named as parties to legal proceedings with respect thereto) are hereby authorized and empowered to take such commercially reasonable additional steps as in their judgment
and discretion may be necessary or proper for the defense of any such legal proceedings or the protection of the validity or priority of this Deed of Trust and the rights, titles, liens and security interests created or evidenced hereby, including,
without limitation, the employment of counsel, the prosecution or defense of litigation, the compromise or discharge of any adverse claims made with respect to the Collateral, the purchase of any tax title and the removal of prior liens or security
interests (including, without limitation, the payment of debts as they mature or the payment in full of matured or unmatured debts, which are secured by these prior liens or security interests), and all commercially reasonable expenses so incurred
of every kind and character shall be subject to and covered by the provisions of Section 2.2 hereof. 
 (i)
Insurance and Casualty. 
  

	 	(i)	Concurrent with the delivery of this Deed of Trust, Grantor shall deliver the Certificates of Insurance listed on Schedule 2 (together with all other insurance policies
Grantor or its Affiliates hold on the Collateral), together with appropriate Endorsements or Appendices identifying Beneficiary as Additional Insured or Loss Payee, as applicable, under such policies. 

  

	 	(ii)	At all times, Grantor shall keep the Collateral insured against loss or damage with insurance policies (in each case naming Beneficiary as Additional Insured or Loss Payee, as
applicable, to the extent allowable under such insurance policies) in such amounts, with such carriers, and with such deductibles as are consistent with the policies, carriers, aggregate amounts and deductibles in place on the date of this Deed of
Trust and identified on Schedule 2, with such modifications from time to time as are consistent with customary and prudent operating standards customary for the electric power generation industry and have been previously notified in writing to the
Beneficiary. 

 (j) Warranty. Grantor will warrant and forever defend the title to the Collateral against
the claims of all persons whomsoever claiming or to claim the same or any part thereof. 
 (k) Legal Compliance.
Grantor shall promptly comply with, or cause to be complied with, and conform to all present and future Laws of Governmental Authorities now existing 
  

			
	 DEED OF TRUST
	  	PAGE 13

 or subsequently created, unless Grantor is diligently proceeding to challenge the validity of said Law or
its applicability to the Collateral, and all covenants, restrictions and conditions now or later of record which may be applicable to any of the Collateral, or to the use, manner of use, occupancy, possession, operation, maintenance, alteration,
repair or reconstruction of any of the Collateral, except to the extent that failure to comply therewith could not, in the aggregate, reasonably be expected to have a material adverse effect upon the value of the Collateral or its usefulness in the
operation of Units 1 and 2. Furthermore, Grantor shall not be deemed to have failed to comply with the provisions of any Laws of Governmental Authorities so long as (a) Grantor is diligently and in good faith pursuing an appropriate challenge
to the validity of such Laws or the applicability of such Laws to the Collateral (provided the Grantor shall (x) indemnify, protect, defend and hold the Trustee and Beneficiary harmless from and against any damages, losses, expenses, costs,
suits or judgments arising from or relating to such non-compliance and (y) cease such challenge and comply therewith prior to the entry of a final non-appealable judgment) or (b) compliance therewith shall have been excused or exempted by
a non-conforming use permit, waiver, extension or forbearance. 
 (l) Leases. Grantor shall not (i) execute an
assignment or pledge of any Lease relating to all or any portion of the Collateral other than in favor of Beneficiary, or (ii) except as expressly permitted under the Intercreditor Agreement, without the prior written consent of Beneficiary
(which consent shall not be unreasonably withheld or delayed), execute any Lease of the Collateral or permit to exist any Lease of any of the Collateral not already in existence prior to the date of this Deed of Trust. 
 (m) Further Assurances. To further assure Beneficiary’s rights under this Deed of Trust, Grantor agrees upon demand of
Beneficiary to do any act or execute any additional documents (including, but not limited to, security agreements on any personalty included or to be included in the Collateral and a separate assignment of each Lease in recordable form) as may be
reasonably required by Beneficiary to confirm the lien of this Deed of Trust and all other rights or benefits conferred on Beneficiary. 
 (n) Beneficiary’s Right to Perform. If Grantor fails to perform any of the covenants or agreements of Grantor hereunder, Beneficiary, without waiving or releasing Grantor from any obligation or default
under this Deed of Trust, may, at any time (but shall be under no obligation to) pay or perform the same, and the amount or cost thereof, with interest at the Default Rate, shall immediately be due from Grantor to Beneficiary and the same shall be
secured by this Deed of Trust and shall be a lien on the Collateral prior to any right, title to, interest in or claim upon the Collateral attaching subsequent to the lien of this Deed of Trust. No payment or advance of money by Beneficiary under
this Section 3.2(n) shall be deemed or construed to cure Grantor’s default or waive any right or remedy of Beneficiary. 
 (o) Inspection. Grantor shall permit the duly authorized representatives of Beneficiary, at any reasonable time and upon reasonable advance notice to make such inspection of the Collateral.

	  	PAGE 14

 (p) Reports. At all times from the date hereof until the termination of the lien
of this Deed of Trust, Grantor, at its own expense, shall furnish to Beneficiary, with a copy to the Secured Parties, the following reports and information at the times indicated below. 
 (i) As soon as available and in any event within 120 days after the end of each fiscal year of Grantor, Grantor shall furnish financial statements of
Grantor relating to Units 1 and 2 as at the end of, and for, such fiscal year, setting forth in each case in comparative form the corresponding figures for the preceding fiscal year, prepared in accordance with GAAP in all material respects
(“Annual Report”), accompanied by a certificate of an officer of Grantor stating that the financial statements fairly represent, in all material respects, the results of operations of Grantor as to Units 1 and 2 as at the end of,
and for, such fiscal year; 
 (ii) As soon as available and in any event within 60 days after the end of each of the first three fiscal
quarterly periods of each fiscal year of Grantor, commencing with the first quarter of 2007, Grantor shall furnish financial statements of Grantor relating to Units 1 and 2 for such quarterly period prepared in a manner consistent with the Annual
Report; 
 Upon reasonable advance notice, Beneficiary shall have the right from time to time, at its own expense, except in the case of a
Trigger Event existing and continuing in which it shall be at Grantor’s expense, to audit the books and records of Grantor with respect to Units 1 and 2. Such audits shall be conducted by Beneficiary so as to result in a minimum disruption in
the ongoing business and affairs of Grantor and shall be conducted during normal business hours at Grantor’s offices or at the offices where Grantor maintains the records relating to the items set forth above. 
 Notwithstanding the foregoing to the contrary, with respect to Sections 3.2 (b)-(p), in the event that the Grantor has failed to comply with the obligations set
forth in such sections, such failure shall not constitute a breach hereof so long as such failure is remedied within sixty (60) days of notice from the Beneficiary of such failure. 
 ARTICLE 4 
 SECURITY AGREEMENT 
 Section 4.1 Grant of Security Interest. Without limiting any of the provisions of this Deed of Trust, Grantor, as debtor, hereby grants to
Beneficiary, as secured party, a security interest in all of Grantor’s remedies, powers, privileges, rights, titles and interests (including all of Grantor’s power, if any, to pass greater title than it has itself) of every kind and
character now owned or hereafter acquired, created or arising in and to the Collateral (including both now and hereafter existing or acquired) to the full extent that the Collateral may be subject to the Uniform Commercial Code of the State of Texas
(the “UCC”). 
 Section 4.2 UCC Rights are not Exclusive. Beneficiary shall have all the rights and remedies of
a secured party under the UCC. Should Beneficiary elect to exercise its rights under 
  

			
	 DEED OF TRUST
	  	PAGE 15

 the UCC as to part of the personal property or fixtures described in this Deed of Trust, such election shall not preclude
Beneficiary or the Trustee from exercising any or all of the rights and remedies granted by the other Articles of this Deed of Trust as to the remaining personal property or fixtures. 
 Section 4.3 Deed of Trust is Also Financing Statement. Beneficiary may, at its election, at any time after delivery of this Deed of Trust,
file an original of this Deed of Trust as a financing statement or sign one or more copies of this Deed of Trust to use as a UCC financing statement. Beneficiary’s signature may be placed between the last sentence of this Deed of Trust and
Grantor’s acknowledgment or may follow Grantor’s acknowledgment. Beneficiary’s signature need not be acknowledged and is not necessary to the effectiveness of this Deed of Trust as a deed of trust, assignment, pledge, security
agreement or (unless otherwise required by applicable law) as a financing statement. 
 Section 4.4 Beneficiary May File Financing
and Continuation Statements. Beneficiary is authorized to file this Deed of Trust, a financing statement or statements and one or more continuation statements in any jurisdiction where Beneficiary deems it reasonably necessary, and at
Beneficiary’s request, Grantor will join Beneficiary in executing one or more financing statements, continuation statements or both pursuant to the UCC, in form reasonably satisfactory to Beneficiary, and will pay the costs of filing or
recording them. 
 ARTICLE 5 
 ASSIGNMENT OF RENTS 
 Section 5.1 Assignment of Rents. Grantor does hereby absolutely and unconditionally assign,
transfer and set over to Beneficiary all Rents under all Leases; subject however to a license hereby granted by Beneficiary to Grantor to collect and receive all of the foregoing (such license evidenced by Beneficiary’s acceptance of the Deed
of Trust), subject to the terms and conditions hereof. Notwithstanding anything contained herein to the contrary, the assignment in this Section 5.1 is an absolute, unconditional and presently effective assignment and not merely a
security interest; provided, however, upon the occurrence of a Trigger Event hereunder such license shall automatically and immediately terminate. It shall not be necessary for Beneficiary to institute any type of legal proceedings or take any other
action whatsoever to enforce the assignment provisions in this Section 5.1. 
 Section 5.2 Beneficiary in Possession.
Beneficiary’s acceptance of this assignment shall not, prior to entry upon and taking possession of the Collateral by Beneficiary, be deemed to constitute Beneficiary a “mortgagee in possession”, nor obligate Beneficiary to appear in
or defend any proceedings relating to any of the Leases or to the Collateral, take any action hereunder, expend any money, incur any expenses, or perform any obligation or liability under the Leases, or assume any obligation for any deposits
delivered to Grantor by any tenant and not delivered to Beneficiary.

 ARTICLE 6 
 REMEDIES 
 Section 6.1 Remedies. Upon the occurrence and continuance of any Trigger Event (as
such term is defined in the Intercreditor Agreement): 
 (a) Acceleration. Beneficiary shall have the option of
declaring all Secured Obligations in their entirety to be immediately due and payable, and the liens evidenced hereby shall be subject to foreclosure in any manner provided for herein or provided for by law as Beneficiary may elect. 
 (b) Pre-Foreclosure Step-In Rights. If a Trigger Event has occurred and is continuing after the expiration of any applicable notice
and cure period and Beneficiary reasonably determines that such Trigger Event is likely to impair the production of electricity at the Collateral, then Beneficiary, acting at the direction of the Required Creditors, in Grantor’s name or in its
own name, may, but shall not be obligated to, act to operate and manage the operation of the Collateral (“Step-In Rights”). Beneficiary shall operate and maintain the Collateral during any Step-In period in accordance with prudent
operating practices customary for the electric power generation industry and in compliance with applicable legal requirements; provided, however, that if Beneficiary exercises its rights under the Big Brown Services Agreement, it being under
no obligation to do so, then Beneficiary shall be deemed to have conclusively complied with the terms of this Section 6.1(b) to the extent of the services provided thereunder and further provided, that in no event shall
Beneficiary be liable for any loss of actual or anticipated business or profits or any special, indirect or consequential damages as the result of the exercise of its Step-In Rights. All costs, expenses and liabilities of every character incurred by
Trustee and/or Beneficiary in administering, managing, operating and controlling the Collateral shall constitute a demand obligation (which obligation Grantor hereby expressly promises to pay) owing by Grantor to Trustee and/or Beneficiary and shall
bear interest from the date of expenditure until paid at the Default Rate, all of which shall constitute a portion of the Secured Obligations and shall be secured by this Deed of Trust. If all costs associated with its operation of the Collateral
have been advanced by Beneficiary (the repayment of which shall be secured by this Deed of Trust), then during any Step-In period, all revenues and profits derived from the operation of the Collateral shall be applied as set forth in the
Intercreditor Agreement. Beneficiary shall exercise the Step-In Rights as the Grantor’s agent (to the extent necessary to comply with the terms and conditions of any licenses or permits applicable to the operation of Units 1 and 2) and solely
in a capacity as mortgagee in possession and the exercise of the Step-In Rights shall not operate, or be deemed, to transfer to Beneficiary any equity or ownership rights in or to the Collateral, or any obligation in connection therewith. The
Step-In Rights provided for herein shall cease upon the earlier of (1) such time, if ever, as Beneficiary consents that the Grantor may resume operation of the Collateral or (2) the date on which the Trigger Event giving rise to the
exercise of such Step-In Rights has been cured to Beneficiary’s reasonable satisfaction or expressly waived in writing by Beneficiary. The terms in this Section 6.1(b) shall apply with respect to each exercise by Beneficiary of any
Step-In Rights. Beneficiary agrees that 
  

			
	 DEED OF TRUST
	  	PAGE 17

 in connection with any exercise of Beneficiary’s Step-In Rights, it shall take reasonable
precautions to preserve the confidentiality or proprietary nature of any of Grantor’s files or records. 
 (c)
Foreclosure. The liens and security interests created or intended to be created hereby shall be subject to foreclosure, repossession and sale in any manner provided for herein or provided for by law, as Beneficiary may elect, and Beneficiary
may exercise any and all of its rights under this Deed of Trust, the UCC and otherwise available at law or in equity. Upon the occurrence of a Trigger Event, Trustee, his successor or substitute, is authorized and empowered and it shall be his
special duty at the request of Beneficiary to sell the Collateral or any part thereof situated in the State of Texas at the courthouse of any county in the State of Texas in which any part of the Collateral is situated, at public venue to the
highest bidder for cash. The sale shall take place at such area of the courthouse as shall be properly designated from time to time by the commissioners court (or, if not so designated by the commissioners court, at the courthouse door) of the
specified county, between the hours of 10 o’clock a.m. and 4 o’clock p.m. (the commencement of such sale to occur within three hours following the time designated in the hereinafter described notice of sale as the earliest time at which
such sale shall occur, if required by Applicable Laws) on the first Tuesday in any month after having given notice of such sale at least twenty-one (21) days before the day of sale of the time, place and terms of said sale (including the
earliest time at which such sale shall occur) in accordance with the statutes of the State of Texas then in force governing sales of real estate under powers conferred by deeds of trust. Notice of a sale of all or part of the Collateral by Trustee
shall be given by posting written notice thereof at the courthouse door (or other area in the courthouse as may be designated for such public notices) of the county in which the sale is to be made, and by filing a copy of the notice in the office of
the county clerk of the county in which the sale is to be made at least twenty-one (21) days preceding the date of the sale, and if the Collateral to be sold is in more than one county, a notice shall be posted at the courthouse door and filed
with the county clerk of each county in which the Collateral is situated. In addition, Beneficiary shall, at least twenty-one (21) days preceding the date of sale, serve written notice of the proposed sale by certified mail on Grantor and each
debtor obligated to pay the Secured Obligations or any portion thereof according to the records of Beneficiary. Service of such notice shall be completed upon deposit of the notice, enclosed in a postpaid certified mail wrapper, properly addressed
to Grantor and each such debtor at the most recent address as shown by the records of Beneficiary, in a post office or official depository under the care and custody of the United States Postal Service. The affidavit of any person having knowledge
of the facts to the effect that such service was completed shall be prima facie evidence of the fact of service. After such sale, Trustee shall make to the purchaser or purchasers at such sale good and sufficient conveyances in the name of Grantor,
conveying the property so sold to the purchaser or purchasers in fee simple with special warranty of title, and shall receive the proceeds of said sale or sales and apply the same as herein provided. Payment of the purchase price to Trustee shall
satisfy the obligation of purchaser at such sale therefor, and such purchaser shall not be responsible for the application thereof. In the event any sale hereunder is not completed or is defective in the opinion of Beneficiary, such sale shall not
exhaust the power of sale hereunder and Beneficiary shall 
  

			
	 DEED OF TRUST
	  	PAGE 18

 have the right to cause a subsequent sale or sales to be made hereunder. Any and all statements of fact
or other recitals made in any deed or deeds given by Trustee or any successor or substitute appointed hereunder as to nonpayment or nonperformance of the Secured Obligations, or as to Beneficiary having declared all of such Secured Obligations to be
due and payable, or as to the request to sell, or as to notice of time, place and terms of sale and of the properties to be sold having been duly given, or as to the refusal, failure or inability to act of Trustee or any substitute or successor, or
as to the appointment of any substitute or successor Trustee, or as to any other act or thing having been duly done by Beneficiary or by Trustee or any substitute or successor, shall be taken as prima facie evidence of the truth of the facts so
stated and recited. Trustee, his successor or substitute, may appoint or delegate any one or more persons as agent to perform any act or acts necessary or incident to any sale held by Trustee, including, without limitation, the posting of notices
and the conducting of sales, but in the name and on behalf of Trustee, his successor or substitute. 
 Section 6.2 Judicial
Foreclosure. Upon the occurrence of a Trigger Event, the Deed of Trust may be foreclosed as to any of the Collateral in any manner permitted by the laws of the State of Texas or of any other state in which any part of the Collateral is situated,
and any foreclosure suit may be brought by Trustee or by Beneficiary. In the event a foreclosure hereunder shall be commenced by Trustee, or his substitute or successor, Beneficiary may at any time before the sale of the Collateral direct Trustee to
abandon the sale, and may then institute suit for the collection of the Secured Obligations and for foreclosure under this Deed of Trust. It is agreed that if Beneficiary should institute a suit for the collection of the Secured Obligations and for
foreclosure under this Deed of Trust, Beneficiary may at any time before the entry of a final judgment in said suit dismiss the same, and require Trustee, his substitute or successor to sell the Collateral in accordance with the provisions of this
Deed of Trust. 
 Section 6.3 Successor or Substitute Trustee. In case of absence, death, inability, refusal or failure of the
Trustee in this Deed of Trust named to act, or in case he should resign (and he is hereby authorized to resign without notice to or consent of Grantor), or if Beneficiary shall desire, with or without cause, to replace the Trustee in this Deed of
Trust named, or to replace any successor or substitute previously named, Beneficiary or any agent or attorney-in-fact for Beneficiary may name, constitute and appoint a successor and substitute trustee (or another one) without formality other than
an appointment and designation in writing, which need not be acknowledged, filed or recorded to be effective, except only in those circumstances, if any, where acknowledgment, filing and/or recording is required by applicable law and such law also
precludes Grantor from effectively waiving such requirement. Upon such appointment, this conveyance shall automatically vest in such substitute trustee, as Trustee, the estate in and title to all of the Collateral, and such substitute Trustee so
appointed and designated shall thereupon hold, possess and exercise all the title, rights, powers and duties in this Deed of Trust conferred on the Trustee named and any previous successor or substitute Trustee, and his conveyance to the purchaser
at any such sale shall be equally valid and effective as if made by the Trustee named in this Deed of Trust. Such right to appoint a substitute Trustee shall exist and may be exercised as often and whenever from any of said causes, or without cause,
as aforesaid, Beneficiary or Beneficiary’s agent or attorney-in-fact elects to exercise it. 
  

			
	 DEED OF TRUST
	  	PAGE 19

 Section 6.4 Right to Receiver. In addition to all other remedies herein provided for, upon
the occurrence and continuance of a Trigger Event, to the extent authorized by applicable law, Beneficiary shall as a matter of right be entitled to the appointment of a receiver or receivers for all or any part of the Collateral, whether such
receivership be incident to a proposed sale of the Collateral or otherwise, and without regard to the value of the Collateral or the solvency of any person or persons liable for the payment of the Secured Obligations, and Grantor does hereby consent
to the appointment of such receiver or receivers, waives any and all defenses to such appointment and agrees not to oppose any application therefor by Beneficiary, but nothing herein is to be construed to deprive Beneficiary of any other right,
remedy or privilege it may now have under the law to have a receiver appointed; provided, however, that the appointment of such receiver, trustee or other appointee by virtue of any court order, statute or regulation shall not impair or in any
manner prejudice the rights of Beneficiary to receive payment of any sum due to Beneficiary with respect to the Secured Obligations. Any such receiver or receivers shall have all the usual powers and duties of receivers in like or similar cases,
including the full power to possess, rent, maintain, repair and operate the Collateral upon such terms and conditions as may be approved by the court. 
 Section 6.5 Separate Sales. To the extent allowed by applicable law, the Collateral may be sold in one or more parcels and in such manner and order as Beneficiary, in its sole discretion, may elect, it
being expressly understood and agreed that the right of sale arising out of any Trigger Event shall not be exhausted by any one or more sales. 
 Section 6.6 Occupancy After Foreclosure. In the event that there is a foreclosure sale hereunder and at the time of such sale Grantor or Grantor’s representatives, successors or assigns or any other Person claiming any
interest in the Collateral by, through or under Grantor, are occupying or using the Collateral or any part thereof, each and all shall immediately become the tenant of the purchaser at such sale, which tenancy shall be a tenancy from day to day,
terminable at the will of either the landlord or tenant, at a rent to be determined by Beneficiary and, if Beneficiary has not set forth the amount of such rent, at a reasonable rental per day based upon the value of the property occupied, such
rental to be due daily to the purchaser. To the extent permitted by applicable law, the purchaser at such sale shall, notwithstanding any language herein to the contrary, have the sole option to demand immediate possession following the sale or to
permit the occupants to remain as tenants at will. In the event that the tenant fails to surrender possession of said property upon demand, the purchaser shall be entitled to institute and maintain a summary action for possession of the Collateral
(such as an action for forcible entry and detainer) in any court having appropriate jurisdiction. 
 Section 6.7 Injunctive
Relief. In the event of any breach of any of the covenants, agreements, terms or conditions contained in this Deed of Trust, and notwithstanding to the contrary any exculpatory or non-recourse language which may be contained herein, Beneficiary
shall be entitled to enjoin such breach and obtain specific performance of any covenant, agreement, term or condition and Beneficiary shall have the right to invoke any equitable right or remedy as though other remedies were not provided for in this
Deed of Trust. 
  

			
	 DEED OF TRUST
	  	PAGE 20

 Section 6.8 Enforcement Expenses. In case of foreclosure of this Deed of Trust or the
exercise of the power of sale, and as often as any proceedings shall be instituted relating thereto, Grantor will pay to Beneficiary a reasonable attorneys’ fee, together, in the case of a judicial foreclosure, with the cost of continuing the
abstract of title to the Real Property to the date of filing such foreclosure, court costs and all other expenses incurred in connection with such proceedings, all of which will be due and payable when suit is filed and will be and become a part of
the Secured Obligations to be paid or collected in such foreclosure. 
 Section 6.9 Waivers. Except as expressly provided in this
Article, presentment, demand, protest and all other notices of any kind are hereby expressly waived. Grantor hereby waives the benefit of any and all laws relative to the appraisement of the Collateral seized and sold under executory process or
other legal process, and consents to the Collateral being sold at Beneficiary’s option, with or without appraisal, to the highest bidder for cash or on such terms as Beneficiary may direct. 
 Section 6.10 Right of Beneficiary to Credit Sale. Upon the occurrence of any sale made under this Deed of Trust, whether made under the power
of sale or by virtue of judicial proceedings or of a judgment or decree of foreclosure and sale, Beneficiary may bid for and acquire the Collateral or any part thereof. In lieu of paying cash therefor, Beneficiary may make settlement for the
purchase price by crediting upon the Secured Obligations or other sums secured by this Deed of Trust the net sales price after deducting therefrom the expenses of sale and the cost of the action and any other sums which Beneficiary is authorized to
deduct under this Deed of Trust or the Intercreditor Agreement. In such event, this Deed of Trust, the Intercreditor Agreement and documents evidencing expenditures secured hereby may be presented to the person or persons conducting the sale in
order that the amount so used or applied may be credited upon the Secured Obligations as having been paid. 
 Section 6.11 Remedies
Cumulative. All remedies herein expressly provided for are cumulative of any and all other remedies existing at law or in equity or otherwise benefiting Beneficiary, or any Secured Party, and Trustee and Beneficiary shall, in addition to the
remedies herein provided, be entitled to avail themselves of all such other remedies as may now or hereafter exist at law or in equity for the collection and enforcement of the Secured Obligations and the enforcement of the covenants herein and the
foreclosure of the liens and security interests evidenced hereby, and resort to any remedy provided for hereunder or under the Intercreditor Agreement or provided for by law, which shall not prevent the concurrent or subsequent employment of any
other appropriate remedy or remedies. 
 Section 6.12 Indemnity. 
 (a) Grantor’s indemnity obligations in this Section 6.12 shall survive termination of this Deed of Trust, provided that Grantor has no
obligation under this Section 6.12 to indemnify the Indemnitees for any Claims arising after the earlier of (a) termination of this Deed of Trust or (b) the Secured Parties foreclose upon the Collateral under
Section 6.1(c). 
  

			
	 DEED OF TRUST
	  	PAGE 21

 (b) Grantor agrees to indemnify, protect, defend and hold harmless the Trustee, the Beneficiary and each
Secured Party and their respective successors, permitted assigns, employees and agents (individually, an “Indemnitee” and collectively, “Indemnitees”) from and against any and all actions, suits, awards, judgments,
amounts paid in settlement with the consent of Grantor (such consent not to be unreasonably withheld, conditioned or delayed), penalties, fines, claims and demands and reasonable out-of-pocket liabilities, losses, costs and expenses (collectively,
“Claims”) which may be imposed on, incurred by or asserted against an Indemnitee in any way relating to or arising or reasonably alleged to arise out of: (i) the financing, ownership, operation or maintenance of the Collateral,
or any part thereof; (ii) any latent or other defects in the Collateral whether or not discoverable by an Indemnitee; (iii) a violation of any Environmental Laws; (iv) any material breach by Grantor of any of its representations or
warranties under this Deed of Trust or any other Collateral Documents or failure by Grantor to perform or observe in any material respect any covenant or agreement to be performed by it under this Deed of Trust or any of the Collateral Documents;
(v) personal injury, death or property damage relating to the Collateral, including Claims based on strict liability in tort, and (vi) the transactions contemplated hereby (including the performance by the Beneficiary of its duties, rights
and obligations hereunder); provided, that the foregoing indemnities in clauses (i) through (vi) shall not, as to any Indemnitee, apply to Claims to the extent they arise out of or result from the gross negligence or willful misconduct of
such Indemnitee as determined in a final, non-appealable judgment by a court of competent jurisdiction. If a Claim is asserted against an Indemnitee by a third party, the Indemnitee shall give Grantor prompt written notice of the Claim and Grantor
shall thereupon notify the Indemnitee whether it desires to defend the Indemnitee against the Claim (provided that Grantor’s failure to or delay in providing such notice shall reduce Grantor’s indemnity obligations hereunder only to the
extent Grantor was actually prejudiced by such failure or delay) and, if so, Grantor shall have the right to defend the Indemnitee in all proceedings with counsel of its own choosing (but reasonably acceptable to the Indemnitee). 
 (c) All liquidated amounts due under the foregoing paragraph which is (i) determined in a final, non-appealable judgment by a court of competent
jurisdiction or (ii) not being contested by Grantor, shall be payable not later than thirty (30) days after written demand therefor. To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in the foregoing
paragraph may be unenforceable in whole or in part because they are violative of any law or public policy, Grantor shall contribute the maximum portion that it is permitted to pay and satisfy under applicable laws to the payment and satisfaction of
all indemnified liabilities incurred pursuant to such paragraph by any Indemnitee. 
 Section 6.13 NO CONSEQUENTIAL DAMAGES.
NEITHER PARTY IS LIABLE TO THE OTHER UNDER THIS DEED OF TRUST FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES OR INJURY THAT MAY OCCUR, IN WHOLE OR IN PART, AS A RESULT OF THE BREACH OF ANY CONTRACT, A TORT, OR ANY OTHER CAUSE, WHETHER OR NOT A
PARTY HAD KNOWLEDGE OF THE CIRCUMSTANCES THAT RESULTED IN THE SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES, OR COULD HAVE FORESEEN THAT SUCH DAMAGES WOULD OCCUR. SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES INCLUDE—AS REPRESENTATIVE

                         , 200x (the “Effective Date”). 
 This award is subject to the Restricted Stock Unit Terms attached hereto and the terms of the Teradyne, Inc. 2006 Equity and Cash Compensation Incentive Plan (the

 Grant #XX 
 Form of Executive Officer Grant Agreement ( 2007 RSU) 

 RESTRICTED STOCK UNIT TERMS 
 This award is governed by and subject to Teradyne’s 2006 Equity and Cash Compensation Incentive Plan (the “Plan”), which, together with
the following provisions, controls the meaning of terms and the rights of the recipient. Capitalized and defined terms used and not defined below will have the meaning set forth in the Plan. In the event of any inconsistencies or differences between
the Plan and these terms, the Plan shall prevail. 
 1. Award Grant, Vesting and Transfer 
 (a) Payment of par value. Teradyne hereby grants to the recipient the right to receive that number of shares of Teradyne common stock as is set
forth on the Notice of Restricted Stock Unit Grant attached hereto. When the underlying shares of Teradyne common stock are issued to the recipient, par value will be deemed paid by the recipient for each share by past services rendered by the
recipient. 
 (b) This award vests yearly on the anniversary of the Effective Date. None of this grant will be vested on the
Effective Date. The grant will vest over four years, beginning on the first anniversary of the Effective Date. Fifty percent (50%) of the shares covered by this grant are “Time Based Shares” because those shares shall vest simply over
a four (4) year period as described below. Fifty percent (50%) of the shares covered by this grant are “Performance Based Shares” because the actual number of those shares that will vest over a four year period is uncertain at
the time of the grant but is expected to be determined near the one year anniversary of the grant based on certain Performance Criteria and a determination of the Performance Award Percentage, as described below. 
 (i) Time Based Shares: 12.5% of the total grant will vest on the first and each of the three subsequent anniversaries of the
Effective Date until 50% of the total grant is fully vested on the fourth anniversary of the Effective Date. 
 (ii)
Performance Based Shares: A percentage ranging from 0 to 100% (known as the “Performance Award Percentage”) of 12.5% of the total grant will vest on the first and each of the three subsequent anniversaries of the Effective Date. The
Performance Award Percentage is a percentage determined by the Committee (as defined below) or the Teradyne Board of Directors using criteria similar to that which is used by the Committee or Teradyne Board of Directors to determine the variable
compensation payout. The Performance Award Percentage shall be as determined near the first anniversary of the Effective Date . 
 The portion of the grant
subject to vesting on each anniversary of the Effective Date that does not vest on such date will be forfeited. Subject to the terms of the Plan, the committee appointed by Teradyne’s Board of Directors to administer the Plan (the
“Committee”) shall have the right to accelerate the date that any installment of this award becomes vested in the event of disability, death, retirement or upon the acquisition of control of Teradyne by another entity. 
 (c) This award will not vest further after termination of employment or other business relationship except in limited certain
circumstances. This award will not vest after the recipient’s employment or other business relationship ends, regardless of the reason, provided, however, that if the recipient’s employment or other business relationship with
Teradyne ends on account of disability, that portion of this award which would have vested under the applicable rule stated in (b) above shall continue to vest for a period of thirty (30) months following his or her termination of
employment or business relationship on account of disability. 
 Employment or another business relationship shall be considered as continuing uninterrupted
during any bona fide leave of absence (such as those attributable to illness or military obligations) provided that the period of such leave does not exceed 90 days or, in the case of an employee, if longer, any period during which the
employee’s right to reemployment is guaranteed by statute. A bona fide leave of absence with the written approval of the Committee shall not be considered an interruption of employment or other business relationship, provided that such written
approval contractually obligates the Company to continue the employment or other business relationship of the recipient after the approved period of absence. 
 (d) No rights as stockholder; Issuance. The recipient shall not have any right in, to or with respect to any shares which may be covered by this award (including but not limited to the right to vote or to
receive dividends) until the award is settled by issuance of shares to the recipient. All vested shares issued in respect of this award will be transferred or issued to the recipient (or his or her estate, in the event of his or her death) promptly
after the date they vest but in any event within 2 1/2 months following the calendar year in which they become
vested (or any earlier date, after vesting, 
 Form of Executive Officer Grant Agreement ( 2007 RSU) 

 required to avoid characterization as non-qualified deferred compensation under Section 409A of the Code). Teradyne
will not be required to transfer or issue any vested shares until arrangements satisfactory to it have been made to address any income, withholding and employment tax requirements which might arise by reason of the vesting and transfer or issuance
of shares. 
 (e) This award may not be assigned or transferred. Other than as provided in Section 11(a) of the Plan, this
award is not assignable or transferable (except by will or the laws of descent and distribution). 
 2. Capital Changes and Business Succession.

 Section 3(c) of the Plan, contains provisions for adjusting (or substituting) the number, vesting schedule, exercise, price and other terms of
outstanding stock-based Awards under the Plan if a recapitalization, stock split, merger, or other specified event occurs, and a Committee of the Board of Directors determines that an adjustment (or substitution) is appropriate. In that event, the
recipient of the award will be notified of the adjustment (or substitution), if any. 
 3. Employment or Business Relationship. 
 Granting this award does not imply any right of continued employment or business relationship by the Company or a Related Corporation, and does not affect the right of
the recipient or the Company or a Related Corporation to terminate employment or a business relationship at any time. 
 4. Stock Registration.

 Shares to be issued under this award are currently registered under the Securities Act of 1933, as amended. If such registration is not in effect at
the time of vesting, the recipient will be required to represent to the Company that he or she is acquiring such shares as an investment and not with a view to the sale of those shares. 
 5. Term. 
 This Agreement will terminate on
                    , 20xx. [Five years from date of grant]
