Allocations and Other Tax Matters 

5.01 Profits. After giving effect to the special allocations set forth in Sections 5.03 and 5.04, and any allocation of
Profits set forth in Section 5.03(b), Profits for any Allocation Year shall be allocated among the Partners in proportion to their respective Percentage Interests. 

5.02 Losses. 
 (a) After
giving effect to the special allocations set forth in Sections 5.03 and 5.04, Losses for any Allocation Year shall be allocated among the Partners in proportion to their respective Percentage Interests. 

(b) The Losses allocated pursuant to Section 5.02(a) shall not exceed the maximum amount of Losses that can be so allocated without
causing any Partner to have an Adjusted Capital Account Deficit at the end of any Allocation Year. In the event some but not all of the Partners would have Adjusted Capital Account Deficits as a result of an allocation of Losses pursuant to
Section 5.02(a), Losses that would otherwise be allocated to a Partner pursuant to Section 5.02(a) but for the limitation set forth in this Section 5.02(b) shall be allocated to the remaining Partners in
proportion to their relative Percentage Interests. All remaining Losses in excess of the limitation set forth in this Section 5.02(b) shall be allocated to the General Partner. Profits for any Allocation Year subsequent to an Allocation
Year for which the limitation set forth in this Section 5.02(b) was applicable shall be allocated (i) first, to reverse any Losses allocated to the General Partner pursuant to the third sentence of this Section 5.02(b),
and (ii) second, to reverse any Losses allocated to the Partners pursuant to the second sentence of this Section 5.02(b) and in proportion to how such Losses were allocated.

 5.03 Special Allocations. The following special allocations shall be made in the following
order: 
 (a) Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f), notwithstanding any other
provision of this Article 5, if there is a net decrease in Minimum Gain during any Allocation Year, each Partner shall be specially allocated items of Partnership income and gain for such Allocation Year (and, if necessary, subsequent
Allocation Years) in an amount equal to such Partner’s share of the net decrease in Minimum Gain, determined in accordance with Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to
the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(g)(2). This Section 5.03(a) is intended
to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(f) and shall be interpreted consistently therewith. 

(b) Partner Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4), notwithstanding any other
provision of this Article 5, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Allocation Year, each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain
attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such Allocation Year (and, if necessary, subsequent Allocation
Years) in an amount equal to such Partner’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4). Allocations
pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4)
and 1.704-2(j)(2). This Section 5.03(b) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith. 

(c) Qualified Income Offset. In the event that any Partner unexpectedly receives any adjustments, allocations, or distributions
described in Regulations Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be allocated to such Partner in an amount and manner sufficient to eliminate, to the extent
required by the Regulations, the Adjusted Capital Account Deficit of such Partner as quickly as possible; provided that an allocation pursuant to this Section 5.03(c) shall be made only if and to the extent that such Partner would
have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 5 have been tentatively made as if this Section 5.03(c) were not in this Agreement. 

(d) Gross Income Allocation. In the event that any Partner has an Adjusted Capital Account Deficit at the end of any Allocation Year,
each such Partner shall be allocated items of Partnership income and gain in the amount of such deficit as quickly as possible; provided that an allocation pursuant to this Section 5.03(d) shall be made only if and to the extent
that such Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 5 have been tentatively made as if Section 5.03(c) and this Section 5.03(d) were not in this
Agreement. 

  
 Page 14 of 30 

 (e) Nonrecourse Deductions. Nonrecourse Deductions for any Allocation Year shall be
allocated among the Partner in proportion to their respective Percentage Interests. 
 (f) Partner Nonrecourse Deductions. Any Partner
Nonrecourse Deductions for any Allocation Year shall be specially allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance
with Regulations Section 1.704-2(i)(1). 
 (g) Nonrecourse Liabilities. Nonrecourse Liabilities of the Partnership described in
Regulations Section 1.752-3(a)(3) shall be allocated among the Partners in the manner chosen by the General Partner and consistent with such section of the Regulations. 

(h) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset, pursuant to Code
Section 734(b) or Code Section 743(b) is required, pursuant to Regulations Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a
Partner in complete liquidation of such Partner’s Partnership Interest, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment
decreases such basis) and such gain or loss shall be specially allocated to the Partners in accordance with their interests in the Partnership in the event Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Partner to whom such
distribution was made in the event Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies. 
 5.04 Curative Allocations. The
allocations set forth in Section 5.03 (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Partners that, to the extent possible, the Regulatory
Allocations shall be offset either with special allocations of other items of Partnership income, gain, loss, or deduction pursuant to this Section 5.04. Therefore, notwithstanding any other provision of this Article 5 (other than
the Regulatory Allocations), the Tax Matters Partner shall make such offsetting special allocations of Partnership income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made,
each Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of this Agreement and all Partnership items were allocated pursuant
to Sections 5.01, 5.02, and 5.03 (other than the Regulatory Allocations). In exercising its discretion under this Section 5.04, the Tax Matters Partner shall take into account future Regulatory Allocations that,
although not yet made, are likely to offset other Regulatory Allocations previously made. 
 5.05 Other Allocation Rules. 

(a) Profits, Losses, and any other items of income, gain, loss, or deduction shall be allocated to the Partners pursuant to this Article
5 as of the last day of each Fiscal Year; provided that Profits, Losses, and such other items shall also be allocated at such times as the Gross Asset Values of the Partnership’s assets are adjusted pursuant to subparagraph
(b) of the definition of “Gross Asset Value” in Section 1.01. 

  
 Page 15 of 30 

 (b) For purposes of determining the Profits, Losses, or any other items allocable to any period,
Profits, Losses, and any such other items shall be determined by the General Partner using any reasonable method under Code Section 706 and the Regulations thereunder. 

5.06 Tax Allocations: Code Section 704(c). 

(a) Except as otherwise provided in this Section 5.06, each item of income, gain, loss and deduction of the Partnership for federal
income tax purposes shall be allocated among the Partners in the same manner as such items are allocated for book purposes under this Article 5. In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss,
and deduction with respect to any Property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such Property to the
Partnership for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of Gross Asset Value). Such allocation shall be made in accordance with the “remedial method” described by
Regulations Section 1.704-3(d). 
 (b) In the event the Gross Asset Value of any Property is adjusted pursuant to subparagraph
(b) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss, and deduction with respect to such Property shall take account of any variation between the adjusted basis of such Property for federal income tax
purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder. Such allocation shall be made in accordance with the “remedial method” described by Regulations
Section 1.704-3(d). 
 (c) In accordance with Treasury Regulations Sections 1.1245-1(e) and 1.250-1(f), any gain allocated to the
Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 5.06(c), be characterized as
“recapture income” in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as “recapture
income.” 
 (d) Any elections or other decisions relating to such allocations shall be made by the General Partner in any manner that
reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 5.06 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing,
any Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement. 

5.07 Tax Elections. 
 (a)
The Partners intend that the Partnership be treated as a partnership or a “disregarded entity” for federal income tax purposes. Accordingly, neither the Tax Matters Partner nor any Limited Partner shall file any election or return on its
own behalf or on behalf of the Partnership that is inconsistent with that intent. 

  
 Page 16 of 30 

 (b) The Partnership shall make the election under Code Section 754 in accordance with the
applicable Regulations issued thereunder, subject to the reservation of the right to seek to revoke any such election upon the General Partner’s determination that such revocation is in the best interests of the Partners. 

(c) Any elections or other decisions relating to tax matters that are not expressly provided herein, shall be made jointly by the Partners in
any manner that reasonably reflects the purpose and intention of this Agreement. 
 5.08 Tax Returns. 

(a) The Tax Matters Partner shall cause to be prepared and timely filed all federal, state, local and foreign income tax returns and reports
required to be filed by the Partnership and its subsidiaries. The Partnership shall provide copies of all the Partnership’s federal, state, local and foreign tax returns (and any schedules or other required filings related to such returns) that
reflect items of income, gain, deduction, loss or credit that flow to separate Partner returns, to the Partners for their review and comment prior to filing, except as otherwise agreed by the Partners. The Partners agree in good faith to resolve any
difference in the tax treatment of any item affecting such returns and schedules. However, if the Partners are unable to resolve the dispute, the position of the Tax Matters Partner shall be followed if nationally recognized tax counsel acceptable
to the Partners provides an opinion that substantial authority exists for such position. Substantial authority shall be given the meaning ascribed to it in Code Section 6662. If the Partners are unable to resolve the dispute prior to the due
date for filing the return, including approved extensions, the position of the Tax Matters Partner shall be followed, and amended returns shall be filed if necessary at such time the dispute is resolved. The costs of the dispute shall be borne by
the Partnership. The Partners agree to file their separate federal income tax returns in a manner consistent with the Partnership’s return, the provisions of this Agreement and in accordance with Applicable Law. 

(b) The Partners shall provide each other with copies of all correspondence or summaries of other communications with the Internal Revenue
Service or any state, local or foreign taxing authority (other than routine correspondence and communications) regarding the tax treatment of the Partnership’s operations. No Partner shall enter into settlement negotiations with the Internal
Revenue Service or any state, local or foreign taxing authority with respect to any issue concerning the Partnership’s income, gains, losses, deductions or credits if the tax adjustment attributable to such issue (assuming the then current
aggregate tax rate) would be $2 million or greater, without first giving reasonable advance notice of such intended action to the other Partners. 

5.09 Tax Matters Partner. 

(a) The General Partner shall be the “Tax Matters Partner” of the Partnership within the meaning of Section 6231(a)(7) of
the Code, and shall act in any similar capacity under the Applicable Law of any state, local or foreign jurisdiction, but only with respect to returns for which items of income, gain, loss, deduction or credit flow to the separate returns of the
Partners. 

  
 Page 17 of 30 

 (b) The Tax Matters Partner shall incur no Liability (except as a result of the gross negligence
or willful misconduct of the Tax Matters Partner) to the Partnership or the other Partners including, but not limited to, Liability for any additional taxes, interest or penalties owed by the other Partners due to adjustments of Partnership items of
income, gain, loss, deduction or credit at the Partnership level. 
 5.10 Duties of Tax Matters Partner. 

(a) The Tax Matters Partner shall cooperate with the other Partners and shall promptly provide the other Partners with copies of notices or
other materials from, and inform the other Partners of discussions engaged with, the Internal Revenue Service or any state, local or foreign taxing authority and shall provide the other Partners with notice of all scheduled proceedings, including
meetings with agents of the Internal Revenue Service or any state, local or foreign taxing authority, technical advice conferences, appellate hearings, and similar conferences and hearings, as soon as possible after receiving notice of the
scheduling of such proceedings, but in any case prior to the date of such scheduled proceedings. 
 (b) The Tax Matters Partner is authorized
and required to represent the Partnership (at the Partnership’s expense) in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and judicial proceedings, and to expend
Partnership funds for professional services and costs associated therewith. Each Partner agrees to cooperate with the Tax Matters Partner and to do or refrain from doing any and all things reasonably required by the Tax Matters Partner to conduct
such proceedings. 
 (c) The Tax Matters Partner shall not extend the period of limitations or assessments without the consent of the other
Partners, which consent shall not be unreasonably withheld. 
 (d) The Tax Matters Partner may request extensions to file any tax return or
statement without the written consent of, but shall so inform, the other Partners. 
 5.11 Survival of Provisions. The provisions of
this Agreement regarding the Partnership’s tax returns and Tax Matters Partner shall survive the termination of the Partnership and the transfer of any Partner’s interest in the Partnership and shall remain in effect for the period of time
necessary to resolve any and all matters regarding the federal, state, local and foreign taxation of the Partnership and items of Partnership income, gain, loss, deduction and credit. 

Article 6 
 Distributions

 6.01 Distributions of Distributable Cash. Within 45 days following the end of each Quarter commencing with the Quarter ending
December 31, 2013, the Partnership shall distribute to the Partners pro rata in accordance with their respective Percentage Interests an amount equal to 100% of Distributable Cash. Notwithstanding any other provision of this Agreement, the
Partnership shall not make a distribution to the Partners on account of their interests in the Partnership if such distribution would violate the TBOC or other applicable law.

 6.02 Liquidating Distributions. Notwithstanding any other provision of this Article
6, distributions with respect to the Quarter in which the winding up and termination of the Partnership occurs shall be made in accordance with Article 12. 

6.03 Distribution in Kind. The Partnership shall not distribute to the Partners any assets in kind unless approved by the Partners in
accordance with this Agreement. If cash and property in kind are to be distributed simultaneously, the Partnership shall distribute such cash and property in kind in the same proportion to each Partner, unless otherwise approved by the Partners in
accordance with this Agreement. 
 Article 7 

Books and Records 
 7.01
Books and Records; Examination. The General Partner shall keep or cause to be kept such books of account and records with respect to the Partnership’s business as it may deem necessary and appropriate. Each Partner and its duly authorized
representatives shall have the right, for any purpose reasonably related to its interest in the Partnership, at any time to examine, or to appoint independent certified public accountants (the fees of which shall be paid by such Partner) to examine,
the books, records and accounts of the Partnership and its Subsidiaries, their operations and all other matters that such Partner may wish to examine, including, without limitation, all documentation relating to actual or proposed transactions
between the Partnership and any Partner or any Affiliate of a Partner. The Partnership’s books of account shall be kept using the method of accounting determined by the General Partner in its sole discretion. 

7.02 Reports. The General Partner shall prepare and send to each Partner (at the same time) promptly such financial information of the
Partnership as a Partner shall from time to time reasonably request, for any purpose reasonably related to its interest in the Partnership. The General Partner shall, for any purpose reasonably related to a Partner’s interest in the
Partnership, permit examination and audit of the Partnership’s books and records by both the internal and independent auditors of its Partners. 

Article 8 
 Management
and Voting 
 8.01 Management. The General Partner shall conduct, direct and manage the business of the Partnership. Except as
otherwise expressly provided in this Agreement, all management powers over the business and affairs of the Partnership shall be exclusively vested in the General Partner, and no Limited Partner shall have any management power over the business and
affairs of the Partnership. In addition to the powers now or hereafter granted a general partner of a limited partnership under Applicable Law or which are granted to the General Partner under any other provision of this Agreement, the General
Partner, subject to Section 8.02, shall have full power and authority to do all things on such terms as it, in its sole discretion, may deem necessary or appropriate to conduct the business of the Partnership and to effectuate the
purposes set forth in Section 2.04. The Partnership shall reimburse the General Partner, on a monthly basis or such other basis as the General Partner may determine, for all direct and indirect costs and expenses incurred by the General
Partner or payments made by the General Partner, in its capacity as the general partner of the Partnership, for and on behalf of the Partnership.

Agreement to the contrary, and subject to the provisions of Section 8.03(c), each of the following matters, and only the following matters, shall constitute a “Unanimous Approval Matter” which requires the prior approval
of the Partners pursuant to Section 8.03(c): 
 (a) any merger, consolidation, reorganization or similar transaction between or
among the Partnership and any Person (other than a transaction between the Partnership and a direct or indirect wholly owned Subsidiary of the Partnership) or any sale or lease of all or substantially all of the Partnership’s assets to any
Person (other than a direct or indirect wholly owned Subsidiary of the Partnership); 
 (b) the creation of any new class of Partnership

(d) the commencement of a voluntary case with respect to the Partnership or any of its Subsidiaries under any applicable bankruptcy, insolvency
or other similar Applicable Law now or hereafter in effect, or the consent to the entry of an order for relief in an involuntary case under any such Applicable Law, or the consent to the appointment of or the taking possession by a receiver,

referencing any determination, decision, approval or other form of authorization by the Partners in accordance with this Agreement. 

8.03 Meetings and Voting. 

(a) Representatives. For purposes of this Article 8, each Partner shall be represented by a designated representative (each, a
“Representative”), who shall be appointed by, and may be removed with or without cause by, the Partner that approved such Person. Each 

  
 Page 20 of 30 

 
Representative shall have the full authority to act on behalf of the Partner who designated such Representative. To the fullest extent permitted by Applicable Law, each Representative shall be
deemed the agent of the Partner that appointed him, and each Representative shall not be an agent of the Partnership or the other Partners. The action of a Representative at a meeting of the Partners (or through a written consent) shall bind the
Partner that designated that Representative, and the other Partners shall be entitled to rely upon such action without further inquiry or investigation as to the actual authority (or lack thereof) of such Representative. 

(b) Meetings and Voting. Meetings of Partners shall be at such times and locations as the General Partner shall determine in its sole
discretion. The General Partner shall provide notice to the Limited Partners of any meetings of Partners in any manner that it deems reasonable and appropriate under the circumstances. Each Partner, acting through its Representative, shall be
entitled to cast one vote on all matters requiring a vote of the Partners under this Agreement. In exercising their voting rights under this Agreement, the Representatives may act at a meeting in person or by proxy or by unanimous written consent
without a meeting. 
 (c) Unanimous Approval Matters. All Unanimous Approval Matters shall be approved by the unanimous affirmative
vote of the Representatives. The parties acknowledge and agree that all references in this Agreement to any determination, decision, approval or other form of authorization by all Partners or each of the Partners shall be deemed to mean that such
determination, decision, approval or other form of authorization shall constitute a Unanimous Approval Matter that requires the unanimous approval of the Partners in accordance with this Section 8.03(c). 

8.04 Reliance by Third Parties. Persons dealing with the Partnership are entitled to rely conclusively upon the power and authority of
the General Partner set forth in this Agreement. Neither a Limited Partner nor its Representative shall have the authority to bind the Partnership or any of its Subsidiaries. 

Article 9

Partnership Interests 
 9.01 Restrictions on Transfers.

Interests to any Person without first obtaining the written approval of each of the other Partners, which approval may be granted or withheld in their sole discretion. 

(b) Transfer by EEP. EEP may transfer all or part of its Partnership Interests to any Person without the approval of any other Partner.

 (c) Transfer by Operation of Law. In the event a Partner shall be party to a merger, consolidation or similar business combination
transaction with another Person or sell all or substantially all its assets to another Person, such Partner may transfer all or part of its Partnership Interests to such other Person without the approval of any other Partner. 

  
 Page 21 of 30 

 (d) Consequences of an Unpermitted Transfer. Any transfer of a Partner’s Partnership
Interest in violation of the applicable provisions of this Agreement shall be void. 
 9.02 Conditions for Admission. No transferee
of all or a portion of the Partnership Interests of any Partner shall be admitted as a Partner hereunder unless such Partnership Interests are transferred in compliance with the applicable provisions of this Agreement. Each such transferee shall
have executed and delivered to the Partnership such instruments as the General Partner deem necessary or appropriate in its reasonable discretion to effectuate the admission of such transferee as a Partner and to confirm the agreement of such
transferee to be bound by all the terms and provisions of this Agreement. The admission of a transferee shall be effective immediately prior to such transfer, and immediately following such admission, the transferor shall cease to be a Partner (to
the extent it transferred its entire Partnership Interest). If the General Partner transfers its entire interest in the Partnership, the transferee General Partner, to the extent admitted as a substitute General Partner, is hereby authorized to, and
shall, continue the Partnership without winding up and termination. 
 9.03 Allocations and Distributions. Subject to applicable
Regulations, upon the transfer of all the Partnership Interests of a Partner as herein provided, the Profit or Loss of the Partnership attributable to the Partnership Interests so transferred for the Fiscal Year in which such transfer occurs shall
be allocated between the transferor and transferee as of the effective date of the assignment, and such allocation shall be based upon any permissible method that is determined by the General Partner and that is provided for in Code Section 706
and the Regulations issued thereunder. 
 9.04 Restriction on Resignation or Withdrawal. Except in connection with a transfer
permitted pursuant to Section 9.01, no Partner shall withdraw from the Partnership without the consent of each of the other Partners. To the extent permitted by law, any purported withdrawal from the Partnership in violation of this
Section 9.04 shall be null and void. 
 Article 10 

Liability, Exculpation and Indemnification 

10.01 Liability for Partnership Obligations. Except as otherwise required by the TBOC, the Liabilities of the Partnership shall be
solely the Liabilities of the Partnership, and no Covered Person (other than the General Partner) shall be obligated personally for any such Liability of the Partnership solely by reason of being a Covered Person. 

10.02 Disclaimer of Duties and Exculpation. 

(a) Except as otherwise expressly provided in this Agreement, no Covered Person shall have any duty (fiduciary or otherwise) or obligation to
the Partnership, the Partners or to any other Person bound by this Agreement, and in taking, or refraining from taking, any action required or permitted under this Agreement or under Applicable Law, each Covered Person shall be entitled to consider
only such interests and factors as such Covered Person deems advisable, including its own interests, and need not consider any interest of or factors affecting, 

  
 Page 22 of 30 

 
any other Covered Person or the Partnership notwithstanding any duty otherwise existing at law or in equity. To the extent that a Covered Person is required or permitted under this Agreement to
act in “good faith” or under another express standard, such Covered Person shall act under such express standard and shall not be subject to any other or different standard under this Agreement or otherwise existing under Applicable Law or
in equity. 
 (b) The provisions of this Agreement, to the extent that they restrict or eliminate the duties (including fiduciary duties) and
Liabilities of a Covered Person otherwise existing under Applicable Law or in equity, are agreed by the Partners to replace such other duties and Liabilities of such Covered Person in their entirety, and no Covered Person shall be liable to the
Partnership, the Partners or any other Person bound by this Agreement for its good faith reliance on the provisions of this Agreement. 
 (c)
To the fullest extent permitted by law, no Covered Person shall be liable to the Partnership, the Partners or any other Person bound by this Agreement for any cost, expense, loss, damage, claim or Liability incurred by reason of any act or omission
performed or omitted by such Covered Person in such capacity, whether or not such Person continues to be a Covered Person at the time of such cost, expense, loss, damage, claim or Liability is incurred or imposed, if the Covered Person acted in good
faith reliance on the provisions of this Agreement, and, with respect to any criminal action or proceeding, such Covered Person had no reasonable cause to believe its conduct was unlawful. 

(d) A Covered Person shall be fully protected from liability to the Partnership, the Partners and any other Person bound by this Agreement in
acting or refraining from acting in good faith reliance upon the records of the Partnership and such other information, opinions, reports or statements presented to the Partnership by any Person as to any matters the Covered Person reasonably
believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Partnership, including information, opinions, reports or statements as to the value and amount of
the assets, Liabilities, Profits and Losses of the Partnership. 
 10.03 Indemnification. 

(a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Covered Persons shall be
indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts
arising from any and all threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Covered Person may
be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as a Covered Person and acting (or refraining to act) in such capacity on behalf of or for the benefit of the Partnership; provided, that the
Covered Person shall not be indemnified and held harmless pursuant to this Agreement if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Covered
Person is seeking indemnification pursuant to this Agreement, the Covered Person acted in bad faith or engaged in intentional fraud, willful misconduct or, in the case of a 

  
 Page 23 of 30 

 
criminal matter, acted with knowledge that the Covered Person’s conduct was unlawful. Any indemnification pursuant to this Section 10.03 shall be made only out of the assets
of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such
indemnification.  
 (b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by a Covered
Person who is indemnified pursuant to Section 10.03(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by a court of
competent jurisdiction determining that, in respect of the matter for which the Covered Person is seeking indemnification pursuant to this Section 10.03, the Covered Person is not entitled to be indemnified upon receipt by the
Partnership of any undertaking by or on behalf of the Covered Person to repay such amount if it shall be ultimately determined that the Covered Person is not entitled to be indemnified as authorized by this Section 10.03. 

(c) The indemnification provided by this Section 10.03 shall be in addition to any other rights to which a Covered Person may be
entitled under any agreement, as a matter of law, in equity or otherwise, both as to actions in the Covered Person’s capacity as a Covered Person and as to actions in any other capacity, and shall continue as to a Covered Person who has ceased
to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Covered Person. 

Article 11 
 Conflicts of
Interest 
 11.01 Transactions with Affiliates. The Partnership and its Subsidiaries shall be permitted to enter into or renew or
extend the term of any agreement or transaction with a Partner or an Affiliate of a Partner on such terms and conditions as the General Partner shall approve in its sole discretion, without the approval of any Limited Partner. 

11.02 Outside Activities. Notwithstanding anything to the contrary in this Agreement or any duty otherwise existing at law or in
equity, (a) the engaging in activities by any Covered Person that are competitive with the business of the Partnership is hereby approved by all Partners, (b) it shall be deemed not to be a breach of any fiduciary duty or any other duty or
obligation of a Partner under this Agreement or otherwise existing under Applicable Law or in equity for such Covered Person to engage in such activities in preference to or to the exclusion of the Partnership, (c) a Covered Person shall have
no obligation under this Agreement or as a result of any duty (including any fiduciary duty) otherwise existing under Applicable Law or in equity, to present business opportunities to the Partnership and (d) the doctrine of corporate
opportunity, or any analogous doctrine, shall not apply to any Covered Person; provided such Covered Person does not engage in such activity as a result of or using confidential or proprietary information provided by or on behalf of the
Partnership to such Covered Person.

 Article 12 

Winding Up and Termination 

12.01 Event Requiring Winding Up. The Partnership shall be terminated and its business and affairs wound up upon the earliest to occur
of any one of the following events: 
 (a) at any time there are no limited partners of the Partnership, unless the business of the
Partnership is continued in accordance with the TBOC; 
 (b) the written consent of all the Partners; 

(c) the withdrawal of the General Partner in accordance with Section 153.155 of the TBOC; or 

(d) the entry of a judicial decree requiring the winding up, dissolution or termination of the Partnership pursuant to the TBOC. 

The bankruptcy, involuntary liquidation or dissolution of a Partner shall cause that Partner to cease to be a partner of the Partnership. Notwithstanding the
foregoing, the Partnership shall not be terminated and its business and affairs shall not be wound up upon the occurrence of any event specified in clause (c) above if, at the time of occurrence of such event, there is at least one remaining
general partner who is hereby authorized to, and shall, carry on the business of the Partnership, or if within ninety (90) days after the date on which such event occurs, the remaining Partners elect in writing to continue the business of the
Partnership and to the appointment, effective as of the date of such event, if required, of one or more additional general partners of the Partnership. Except as provided in this paragraph, and to the fullest extent permitted by the TBOC, the
occurrence of an event that causes a Partner to cease to be a partner of the Partnership shall not, in and of itself, cause the Partnership to be terminated or its business or affairs to be wound up, and upon the occurrence of such an event, the
business of the Partnership shall, to the extent permitted by the TBOC, continue without termination. 
 12.02 Winding Up Procedures of
Partnership. The Partnership’s business shall be wound up in an orderly manner. The General Partner shall (unless the General Partner (or, if no General Partner, the remaining Limited Partners) elects to appoint a liquidating trustee) wind
up the affairs of the Partnership pursuant to this Agreement. In performing its duties, the General Partner or liquidating trustee is authorized to sell, distribute, exchange or otherwise dispose of the assets of the Partnership in accordance with
the TBOC and in any reasonable manner that the General Partner or liquidating trustee shall determine to be in the best interest of the Partners or their successors-in-interest. The General Partner or liquidating trustee shall take full account of
the Partnership’s Liabilities and Property and shall cause the Property or the proceeds from the sale thereof, to the extent sufficient therefor, to be applied and distributed, to the maximum extent permitted by Applicable Law, in the following
order: 
 (a) First, to creditors, including Partners who are creditors, to the extent permitted by law, in satisfaction of all of the
Partnership’s Liabilities (whether by payment or the making of reasonable provision for payment thereof to the extent required by Section 153.504 of the TBOC), other than Liabilities for distribution to Partners under Sections 153.111 or
153.209 of the TBOC; 
 (b) Second, to the Partners and former Partners of the Partnership in satisfaction of Liabilities for distribution
under Sections 153.111 or 153.209 of the TBOC; and 

  
 Page 25 of 30 

 (c) The balance, if any, to the Partners in accordance with the positive balance in their Capital
Accounts, after giving effect to all contributions, distributions, and allocations for all periods. 
 12.03 Compliance with Certain
Requirements of Regulations; Deficit Capital Accounts. In the event the Partnership is “liquidated” within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant to this Article 12 to
the Partners who have positive Capital Accounts in compliance with Regulations Section 1.704- 1(b)(2)(ii)(b)(2). If any Limited Partner has a deficit balance in its Capital Account (after giving effect to all contributions, distributions, and
allocations for all Allocation Years, including the Allocation Year during which such liquidation occurs), such Limited Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and
such deficit shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever. 
 12.04 Deemed
Distribution and Recontribution. Notwithstanding any other provision of this Article 12, in the event the Partnership is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g) but no actual event requiring winding
up under the TBOC has occurred, the Property shall not be liquidated, the Partnership’s debts and other Liabilities shall not be paid or discharged, and the Partnership’s affairs shall not be wound up. Instead, solely for federal income
tax purposes, the Partnership shall be deemed to have contributed all its Property and Liabilities to a new limited partnership in exchange for an interest in such new limited partnership and, immediately thereafter, the Partnership will be deemed
to liquidate by distributing interests in the new limited partnership to the Partners. 
 12.05 Distribution of Property. In the
event the General Partner determines that it is necessary in connection with the winding up of the Partnership to make a distribution of property in kind, such property shall be transferred and conveyed to the Partners so as to vest in each of them
as a tenant in common an undivided interest in the whole of such property, but otherwise in accordance with Section 12.03. 

12.06 Termination of Partnership. The Partnership shall terminate when all assets of the Partnership, after payment of or due provision
for all Liabilities of the Partnership, shall have been distributed to the Partners in the manner provided for in this Agreement, and the Certificate shall have been canceled in the manner provided by the TBOC.

 Exhibit 4.1 

CORNING INCORPORATED 
 3.70% Notes
due 2023 
 Officers’ Certificate 

Pursuant to the Indenture, dated as of November 8, 2000 (the “Indenture”), as supplemented, between Corning Incorporated (the
“Company”) and The Bank of New York Mellon Trust Company, N.A. (successor to JPMorgan Chase Bank, N.A., formerly The Chase Manhattan Bank), as Trustee (the “Trustee”), and resolutions duly adopted by the Board of Directors of the
Company at a meeting of the Board of Directors duly called and held on April 25, 2013, at which a quorum was present in person or by teleconference and acting throughout (together, the “Resolutions”), this Officers’ Certificate
is being delivered to the Trustee to establish the terms of a series of Securities in accordance with Section 301 of the Indenture and to establish the form of the Securities of such series in accordance with Section 201 of the Indenture.

 Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture. 

A. Establishment of Series pursuant to Section 301 of Indenture. 

There is hereby established pursuant to Section 301 of the Indenture a series of Securities which shall have the following terms: 

(1) The Securities shall bear the title “3.70% Notes due 2023” (the “Notes”). 

(2) The aggregate principal amount of Notes to be issued pursuant to this Officers’ Certificate shall be initially limited to
$250,000,000 (except for Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306, 906 or 1107 of the Indenture and except for any Notes which,
pursuant to Section 303 of the Indenture, are deemed never to have been authenticated and delivered thereunder). The Company may from time to time, without consent of the existing Holders create and issue additional Notes (the “Additional
Notes”) having the same terms and conditions as the Notes in all respects, except for the issue date, issue price and, under some circumstances, the first payment of interest thereon, but only if such Additional Notes are fungible with the
Notes for United States federal income tax purposes. Such Additional Notes, at the Company’s determination and in accordance with the provisions of the Indenture, will be consolidated with and form a single series with the previously
outstanding Notes for U.S. federal income tax purposes and for all purposes under the Indenture, including, without limitation, amendments, waivers and redemptions. The aggregate principal amount of the Additional Notes, if any, shall be unlimited.

 (3) Interest will be payable to the Person in whose name a Note (or any Predecessor Security) is
registered at the close of business on the Regular Record Date (as defined below) next preceding each Interest Payment Date (as defined below); provided, however, that interest payable on the respective Maturity Date of the Notes shall be payable to
the Person to whom principal shall be payable. 
 (4) The date on which the principal of the Notes is due and payable shall be
November 15, 2023. 
 (5) The Notes shall bear interest at the rate of 3.70% per annum (based upon a 360-day year consisting of
twelve 30-day months), from and including November 18, 2013, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semiannually on May 15 and
November 15 in each year, commencing on May 15, 2014, until the principal thereof is paid or made available for payment. Each such May 15 or November 15 shall be an “Interest Payment Date” for the Notes, and each
May 1 or November 1 (whether or not a Business Day), as the case may be, next preceding an Interest Payment Date shall be the “Regular Record Date” for the interest payable on such Interest Payment Date. 

(6) Principal of and interest on the Notes will be payable, and, except as provided in Section 305 of the Indenture with respect to any
Global Security (as defined below), the transfer of the Notes will be registrable and Notes will be exchangeable for Notes bearing identical terms and provisions at the corporate trust office of The Bank of New York Mellon Trust Company, N.A. (the
“Paying Agent”), in the Borough of Manhattan, The City of New York. 
 (7) The Notes shall be redeemable as follows: 

The Notes will be redeemable in whole at any time or in part from time to time, at the option of the Company. If the Company redeems Notes
more than 90 days prior to their scheduled maturity date, the redemption price will be equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed; or (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the
then current Treasury Rate plus 15 basis points. If the Company redeems Notes on or after the date that is 90 days prior to the Scheduled maturity date of the Notes, the redemption price will be equal to 100% of the principal amount of the Notes to
be redeemed. 
 In any redemption, the Company will pay accrued and unpaid interest on the principal amount of the Notes being redeemed to
but not including the Redemption Date. 

 In connection with such optional redemption, the following defined terms apply: 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of the Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the
Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers
that the Company appoints to act as the Independent Investment Banker from time to time. 
 “Redemption Date” means the date fixed
for redemption of the Notes by or pursuant to the Indenture. 
 “Reference Treasury Dealer” means each of Deutsche Bank Securities
Inc. and J.P. Morgan Securities LLC and their respective successors, and three other firms that are primary U.S. Government securities dealers (each a “Primary Treasury Dealer”) which the Company will specify from time to time; provided,
however, that if any of them ceases to be a Primary Treasury Dealer, the Company will substitute another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average,
as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such
Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury
Rate” means, with respect to any Redemption Date, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of
its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

If the Company decides to redeem less than all of the outstanding Notes, the Trustee will select the Notes to be redeemed in accordance with the Applicable
Procedures or by any other method the Trustee considers fair and appropriate. 

 Notice of redemption will be mailed at least 30 but not more than 60 days before the Redemption
Date to each Holder of record of the Notes to be redeemed at its registered address. 
 The Notes are subject to repurchase at the option of
the Holders, as follows: 
 If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Notes,
it will be required to make an offer to each Holder to repurchase all or, at the Holder’s option, any part (equal to $2,000 or any multiple of $1,000 in excess thereof), of each Holder’s Notes pursuant to the offer described below (the
“Change of Control Offer”). In the Change of Control Offer, the Company will be required to offer to repurchase each Holder’s Notes in cash at a price equal to 101% of the aggregate principal amount of Notes repurchased, plus any
accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase (the “Change of Control Payment”). 

Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control, but after
the public announcement of a pending Change of Control, the Company will be required to send to each Holder of Notes a notice describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to
repurchase such Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “Change of Control Payment Date”). The notice, if mailed prior
to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. 

On the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 

 

	 	•	 	accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

  

	 	•	 	deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 

 

	 	•	 	deliver or cause to be delivered to the Trustee the Notes properly accepted together with an officer’s certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the
Company. 

 The Paying Agent will be required to promptly mail, to each Holder who properly tendered Notes, the Change of
Control Payment for such Notes, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each new note will be in a principal amount of $2,000 or a multiple of $1,000 in excess thereof. 

 The Company will not be required to make a Change of Control Offer upon a Change of Control
Triggering Event if a third party makes an offer to purchase the Notes in the manner, at the times and otherwise in compliance with the requirements for an offer to purchase made by the Company and such third party purchases all Notes properly
tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default as though it were the
date of the Change of Control Triggering Event. 
 The Company will not repurchase any Notes if there has occurred and is continuing on the
Change of Control Payment Date an Event of Default, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 

Except as provided in the last sentence of the next paragraph, the Company may only make an amendment or modification to the provisions
obligating it to repurchase Notes upon a Change of Control Triggering Event which adversely affects the interest of any Holder, with the consent of each Holder of Notes to be affected by such amendment or modification. 

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provision of any such securities laws or regulations
conflicts with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes
by virtue of not complying with the Change of Control Offer provisions as a result of any such conflict. 
 For these purposes, the
following terms will be applicable: 
 “Change of Control” means the occurrence of any one of the following: (1) the
direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s
properties or assets and those of its subsidiaries, taken as a whole, to one or more persons, other than to the Company or one of its subsidiaries; (2) the first day on which a majority of the members of the Company’s board of directors is
not composed of Continuing Directors; (3) the consummation of any transaction including, without limitation, any merger, amalgamation, arrangement or consolidation the result of which is that any person becomes the beneficial owner, directly or
indirectly, of more than 50% of the Company’s Voting Stock, measured by voting power rather than number of shares; (4) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or
into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction

 
where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the
surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution (other than its
liquidation into a newly formed holding company). Notwithstanding the foregoing, a transaction described in clause (3) above will not be deemed to involve a Change of Control if (1) the Company becomes a direct or indirect wholly-owned
subsidiary of a holding company (which shall include a direct or indirect parent company of such holding company) and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are
substantially the same as, and hold in substantially the same proportions as, the holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person, other than a holding
company satisfying the requirements of this sentence, is the beneficial owner, directly or indirectly, of more than 50% of the then outstanding Voting Stock, measured by voting power, of such holding company or its parent company. Following any such
transaction, references in this definition to the Company shall be deemed to refer to such holding company. For the purposes of this definition, “person” and “beneficial owner” have the meanings used in Section 13(d) of the
Exchange Act and the related rules and regulations thereunder. 
 “Change of Control Triggering Event” means the Notes
cease to be rated Investment Grade by each of the Rating Agencies on any date during the 60-day period (the “Trigger Period”) following the earlier date of (1) the first public announcement of the Change of Control or the
Company’s intention to effect a Change of Control and (2) the consummation of such Change of Control, which Trigger Period will be extended following consummation of a Change of Control for so long as the rating of the Notes is under
publicly announced consideration for possible downgrade by any of the Rating Agencies. Unless at least one Rating Agency is providing a rating for the long-term unsecured debt of the Company at the commencement of any Trigger Period, the Notes will
be deemed to have ceased to be rated Investment Grade during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and
until such Change of Control has actually been consummated. 
 “Continuing Directors” means, as of any date of
determination, any member of the Company’s Board of Directors who (1) was a member of the Company’s board of directors on the date the Notes were originally issued; or (2) was nominated for election, elected or appointed to the
Company’s Board of Directors with the approval of a majority of the Continuing Directors who were members of the Company’s board of directors at the time of such nomination, election or appointment (either by specific action of the board
of directors or by approval by such directors of the Company’s proxy statement in which such member was named as a nominee for election as a director). 

“Fitch” means Fitch Inc., and its successors. 

 “Investment Grade” means a rating equal to or higher than BBB- (or the
equivalent) by Fitch, Baa3 (or the equivalent) by Moody’s or BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company. 

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors. 

“Rating Agencies” means (a) each of Fitch, Moody’s and S&P; and (b) if any of the Rating Agencies
ceases to provide rating services to issuers or investors, a “nationally recognized statistical rating organization” as defined pursuant to Section 3(a)(62) of the Exchange Act that is selected by the Company (as certified by the
Company’s chief executive officer or chief financial officer) as a replacement for Fitch, Moody’s or S&P, or all of them, as the case may be. 

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and its
successors. 
 “Voting Stock” of any specified person as of any date means the capital stock of such person that is at the
time entitled to vote generally in the election of the board of directors of such person. 
 (8) Except as provided in paragraph (7), the
Company shall not be obligated to redeem or purchase any Notes pursuant to any sinking fund or analogous provisions or at the option of any Holder. 

(9) Notes may be issued only in fully registered form and the authorized denomination of the Notes shall be $2,000 and any integral multiple
of $1,000 in excess thereof. 
 (10) The amount of payments of principal of and any premium or interest on the Notes will not be determined
with reference to an index or pursuant to a formula. 
 (11) The Notes shall be denominated, and payments of principal of and interest on
the Notes will be made, in United States dollars. 
 (12) The payments of principal of and interest on the Notes shall not be payable at the
