Representatives, and which is listed on Schedule II-A hereto and herein called a “Permitted Free Writing Prospectus.”

(d) The Company agrees that if at any time following issuance of a Permitted Free Writing Prospectus or the Limited Use Free Writing Prospectus any event occurred or occurs as a result of which such Permitted Free Writing Prospectus or the Limited Use Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Final Supplemented Prospectus or include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter a free writing prospectus or other document, the use of which has been consented to by the Representatives, which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in a Permitted Free Writing Prospectus or the Limited Use Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives expressly for use therein.

(e) The Company agrees that if there occurs an event or development as a result of which the Pricing Disclosure Package would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will notify the Representatives so that any use of the Pricing Disclosure Package may cease until it is amended or supplemented.

SECTION 4. COVENANTS OF THE COMPANY . The Company covenants with the Underwriters as follows:

(a) The Company, on or prior to the Closing Date, will deliver to the Underwriters conformed copies of the Registration Statement as originally filed and of all amendments thereto, heretofore or hereafter made, including any post-effective amendment (in each case including all exhibits filed therewith, and including unsigned copies of each consent and certificate included therein or filed as an exhibit thereto, except exhibits incorporated by reference, unless specifically requested). As soon as the Company is advised thereof, it will advise the Representatives orally of the issuance of any stop order under the 1933 Act with respect to the Registration Statement, or the institution of any proceedings for that purpose or pursuant to Section 8A of the 1933 Act against the Company or related to the offering, of which the Company shall have received notice, and will use its best efforts to prevent the issuance of any such stop order and to secure the prompt removal thereof, if issued. The Company will deliver to the Representatives sufficient conformed copies of the Registration Statement, the

Base Prospectus, the Pricing Prospectus and the Final Supplemented Prospectus and of all supplements and amendments thereto (in each case without exhibits) for distribution to the Underwriters and, from time to time, as many copies of the Base Prospectus, the Pricing Prospectus and the Final Supplemented Prospectus as the Underwriters may reasonably request for the purposes contemplated by the 1933 Act or the 1934 Act.

(b) The Company will furnish the Underwriters with written or electronic copies of each amendment and supplement to the Final Supplemented Prospectus relating to the offering of the Senior Notes in such quantities as the Underwriters may from time to time reasonably request. If, during the period (not exceeding nine months) when the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) shall be required by law in connection with the sale of any Senior Notes by an Underwriter, any event relating to or affecting the Company, or of which the Company shall be advised in writing by the Representatives, shall occur, which in the opinion of the Company or of Underwriters’ counsel should be set forth in a supplement to or an amendment of the Final Supplemented Prospectus, as the case may be, in order to make the Final Supplemented Prospectus not misleading in light of the circumstances when it (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) is delivered, or if for any other reason it shall be necessary during such period to amend or supplement the Final Supplemented Prospectus or to file under the 1934 Act any document incorporated by reference in the Final Supplemented Prospectus in order to comply with the 1933 Act or the 1934 Act, the Company forthwith will (i) notify the Underwriters to suspend solicitation of purchases of the Senior Notes and (ii) at its expense, make any such filing or prepare and furnish to the Underwriters a reasonable number of copies of a supplement or supplements or an amendment or amendments to the Final Supplemented Prospectus which will supplement or amend the Final Supplemented Prospectus so that, as supplemented or amended, it will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances when the Final Supplemented Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) is delivered, not misleading or which will effect any other necessary compliance. In case any Underwriter is required to deliver a prospectus in connection with the sale of any Senior Notes after the expiration of the period specified in the preceding sentence, the Company, upon the request of such Underwriter, will furnish to such Underwriter, at the expense of such Underwriter, a reasonable quantity of a supplemented or amended prospectus, or supplements or amendments to the Final Supplemented Prospectus, complying with Section 10(a) of the 1933 Act. During the period specified in the second sentence of this subsection, the Company will continue to prepare and file with the Commission on a timely basis all documents or amendments required under the 1934 Act and the rules and regulations thereunder; provided, that the Company shall not file such documents or amendments without also furnishing copies thereof prior to such filing to the Representatives and Hunton & Williams LLP.

(c) The Company will endeavor, in cooperation with the Underwriters, to qualify the Senior Notes for offering and sale under the applicable securities laws of such states and the other jurisdictions of the United States as the Representatives may designate; provided, however, that the Company shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file a consent to service of process or to file annual reports or to comply with any other requirements in connection with such qualification deemed by the Company to be unduly burdensome.

(d) The Company will make generally available to its security holders as soon as practicable but not later than 45 days after the close of the period covered thereby, an earnings statement of the Company (in form complying with the provisions of Rule 158 of the rules and regulations under the 1933 Act) covering a twelve-month period beginning not later than the first day of the Company’s fiscal quarter next following the “effective date” (as defined in Rule 158) of the Registration Statement.

(e) As soon as practicable after the date of this Agreement, and in any event within the time prescribed by Rule 424 under the 1933 Act, the Company will file the Final Supplemented Prospectus, in a form approved by the Representatives, such approval not to be unreasonably withheld, with the Commission and will advise the Representatives of such filing and will confirm such advice in writing. Furthermore, the Company will make any other required filings pursuant to Rule 433(d)(1) under the 1933 Act within the time required by such Rule.

(f) During a period of 15 days from the date of this Agreement, the Company will not, without the Representatives’ prior written consent, directly or indirectly, sell, offer to sell, grant any option for the sale of, or otherwise dispose of, any Senior Notes or any security convertible into or exchangeable into or exercisable for the Senior Notes or any debt securities substantially similar to the Senior Notes (except for the Senior Notes issued pursuant to this Agreement). The Representatives agree that commercial paper or other debt securities with scheduled maturities of less than one year are not subject to this Section 4(f).

(g) If at any time when Senior Notes remain unsold by the Underwriters, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) under the 1933 Act or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Senior Notes, in a form satisfactory to the Representatives, (iii) use its reasonable best efforts to cause such registration statement or post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other reasonable action necessary or appropriate to permit the public offering and sale of the Senior Notes to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

In case such conditions shall not have been fulfilled, this Agreement may be terminated by the Company by mailing or delivering written notice thereof to the Representatives. Any such termination shall be without liability of any party to any other party except as otherwise provided in Sections 5, 8 and 10(b) hereof.

SECTION 8. INDEMNIFICATION .

(a) The Company agrees to indemnify and hold harmless each of the Underwriters and each person, if any, who controls any such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise, and to reimburse any such Underwriter and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any actions, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Limited Use Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus or, if the Company shall furnish to the Underwriters any amendments or any supplements thereto, or shall make any filings pursuant to Section 13 or 14 of the 1934 Act which are incorporated therein by reference, in the Limited Use

Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus, the Final Supplemented Prospectus as so amended or supplemented, or in any free writing prospectus used by the Company other than a Permitted Free Writing Prospectus or the Limited Use Free Writing Prospectus, or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such untrue statement or alleged untrue statement or omission or alleged omission which was made in such Limited Use Free Writing Prospectus, Registration Statement, Preliminary Prospectus, Base Prospectus, Pricing Prospectus, Permitted Free Writing Prospectus or Final Supplemented Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives for use therein. Each Underwriter agrees, within ten days after the receipt by it of notice of the commencement of any action in respect of which indemnity may be sought by it, or by any person controlling it, from the Company on account of its agreement contained in this Section 8, to notify the Company in writing of the commencement thereof but the omission of such Underwriter so to notify the Company of any such action shall not release the Company from any liability which it may have to such Underwriter or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8. In case any such action shall be brought against an Underwriter or any such person controlling such Underwriter and such Underwriter shall notify the Company of the commencement thereof as above provided, the Company shall be entitled to participate in (and, to the extent that it shall wish, including the selection of counsel, to direct) the defense thereof, at its own expense. In case the Company elects to direct such defense and select such counsel, any Underwriter or controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel has been authorized in writing by the Company in connection with defending such action. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors and such of its officers who have signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 8(a) hereof, but only with respect to alleged untrue statements or omissions made in the Limited Use Free Writing Prospectus, the Registration Statement, the Preliminary Prospectus, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus, or such documents

as amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives for use therein.

SECTION 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY . All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by, or on behalf of the Company and shall survive delivery of the Senior Notes to the Underwriters.

SECTION 10. TERMINATION OF AGREEMENT .

(a) The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Date if (i) trading in securities on the New York Stock Exchange shall have been generally suspended or there shall have been a material disruption in settlement in securities generally, (ii) minimum or maximum ranges for prices shall have been generally established on the New York Stock Exchange by the Commission or by the New York Stock Exchange, (iii) a general banking moratorium shall have been declared by federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of major hostilities in which the United States is involved, any declaration of war by the United States Congress or any other substantial national or international calamity, crisis or emergency (including, without limitation, acts of terrorism) affecting the United States, in any such case provided for in clauses (i) through (iv) with the result that, in the reasonable judgment of the Representatives, the offering, sale or delivery of the Senior Notes on the terms and in the manner contemplated by this Agreement and the Final Supplemented Prospectus shall have been materially impaired.

(b) If this Agreement shall be terminated by the Representatives pursuant to subsection (a) above or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, then in any such case, the Company will reimburse the Underwriters for the reasonable fees and disbursements of Hunton & Williams LLP and for the out of pocket expenses (in an amount not exceeding $10,000) reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Senior Notes and, upon such reimbursement, the Company shall be absolved from any further liability hereunder, except as provided in Sections 5 and 8 hereof.

SECTION 11. DEFAULT BY AN UNDERWRITER . If an Underwriter shall fail on the Closing Date to purchase the Senior Notes that it is obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the principal amount of Defaulted Securities does not exceed 10% of the Senior Notes, each of the non-defaulting Underwriters shall be obligated, severally and not

jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the principal amount of Defaulted Securities exceeds 10% of the Senior Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the Pricing Prospectus or the Final Supplemented Prospectus or in any other documents or arrangements.

SECTION 12. NOTICES . All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Section 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

III-3

deemed necessary to express the opinions hereinafter set forth. In such examination, we have assumed (i) the genuineness of all signatures, (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.

The Indenture and the Underwriting Agreement are herein referred to collectively as the “Agreements.”

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that:

1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware and has due corporate authority to conduct the business in which it is engaged, to own and operate the properties used by it in such business and to enter into and perform its obligations under the Agreements and the Notes.

2. The execution, delivery and performance by the Company of the Underwriting Agreement have been duly authorized by all necessary corporate action, and the Underwriting Agreement has been duly executed and delivered by the Company.

3. All orders, consents or other authorizations or approvals of the Commission legally required for the issuance and sale of the Notes have been obtained; such orders are sufficient for the issuance and sale of the Notes; the issuance and sale of the Notes conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval pursuant to the Delaware General Corporation Law or any Georgia or United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and sale of the Notes in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, subject to the qualifications that the enforceability of the Company’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles

III-4

of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. Each of the Indenture and the Notes conforms as to legal matters in all material respects to the descriptions thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

7. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

8. The execution and delivery by the Company of the Indenture and the Underwriting Agreement and the issuance and sale by the Company of the Notes do not, and, if the Company were now to perform its obligations under the Indenture and the Underwriting Agreement, such performance would not, result in any violation of the Certificate of Incorporation or the By-Laws of the Company, or conflict with, or result in a breach of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company under (A) any contract, indenture, mortgage, loan agreement, note, lease or any other agreement or instrument that has been filed as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 or any subsequent Exchange Act Document, (B) any existing applicable law, rule or regulation applicable to the Company (other than the securities or blue sky laws of any jurisdiction, as to which we express no opinion) or (C) any judgment, order or decree known to us of any government, governmental instrumentality or court, domestic or foreign, or any regulatory body or administrative agency or other governmental body having jurisdiction over the Company.

9. The Company is not and, after giving effect to the offering and sale of the Notes, will not be an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

10. The statements set forth in the Pricing Disclosure Package and the Final Supplemented Prospectus under the heading “Material United States Federal Income Tax Considerations” insofar as they purport to constitute summaries of matters of United States federal income tax law, constitute accurate summaries in all material respects subject to the qualifications set forth therein.

The attorneys in this firm that are rendering this opinion are members of the State Bar of Georgia and we do not purport to express any opinion herein concerning any law other than the laws of the State of Georgia, the federal law of the United States, the Delaware General Corporation Law and, to the extent set forth herein, the laws of the State of New York.

In the above capacity, we have examined the Company’s registration statement on Form S-3 (File No. 333-202413) pertaining to the Notes and certain other securities filed by the Company under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated March 2, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement dated May 19,

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

We have participated in various conferences with the Company, its representatives, representatives of the independent public or certified public accountants of the Company and your counsel at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraphs 6 and 8 of our opinion to you related to the Indenture and the Notes dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:

(i) the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading,

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

III-9

(iii) the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,

except that in each case we express no belief with respect to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the caption “Description of the Notes ─ Book-Entry Only Issuance ─ The Depository Trust Company.”

Subject to and on the basis of the foregoing, we further advise you that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of May 19, 2016, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that each Exchange Act Document, as of its date of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no belief as to the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents.

This letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent.

The Notes are being issued under the Senior Note Indenture, dated as of January 1, 2007 (the “Original Indenture”), between the Company and Wells Fargo, as trustee (in such capacity, the “Trustee”), as heretofore supplemented and as further supplemented by a twelfth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2018 Senior Notes (the “Twelfth Supplemental Indenture”), a thirteenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2019 Senior Notes (the “Thirteenth Supplemental Indenture”), a fourteenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2021 Senior Notes (the “Fourteenth Supplemental Indenture”), a fifteenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2023 Senior Notes (the “Fifteenth Supplemental Indenture”), a sixteenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2026 Senior Notes (the “Sixteenth Supplemental Indenture”), a seventeenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2036 Senior Notes (the “Seventeenth Supplemental Indenture”) and an eighteenth supplemental indenture, dated as of May 24, 2016, to the Original Indenture relating to the 2046 Senior Notes (the “Eighteenth Supplemental Indenture” and, together with the Twelfth Supplemental Indenture, the Thirteenth Supplemental Indenture, the Fourteenth Supplemental Indenture, the Fifteenth Supplemental Indenture, the Sixteenth Supplemental Indenture and the Seventeenth Supplemental Indenture, the “Supplemental Indentures”). The Supplemental Indentures, the Original Indenture and any other amendments or supplements thereto are referred to herein as the “Indenture.”

For purposes of this opinion, we have reviewed the Indenture and such other documents, records and papers, and satisfied ourselves as to such other matters, as we have deemed necessary or appropriate for this opinion. As to questions of fact material to this opinion, we have relied on certificates of Wells Fargo and of public officials. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies or forms and the authenticity of the originals of such latter documents. We have assumed that Wells Fargo has been duly formed and that the Indenture has been duly authorized, executed and delivered by the Company and constitutes the valid and binding agreement of, and is enforceable in accordance with its terms against, the Company.

Based upon the foregoing and subject to the qualifications below, we are of the opinion that:

1) Based solely on a certificate from the Comptroller of the Currency, Wells Fargo is a national banking association formed under the laws of the United States and is authorized thereunder to transact the business of banking and exercise fiduciary powers.

IV-2

2) Each of the Supplemental Indentures has been duly authorized, executed and delivered by Wells Fargo and the Indenture constitutes a valid and binding agreement of Wells Fargo enforceable against Wells Fargo in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and by an implied covenant of reasonableness, good faith and fair dealing.

We are members of the Bar of the State of New York and, for purposes of this opinion, do not hold ourselves out as experts on the laws of any jurisdiction other than the State of New York and the federal law of the United States. The opinions expressed herein are limited to matters governed by the laws of the State of New York and the federal law of the United States.

This opinion is solely for your benefit in connection with the issuance and sale by the Company of the Notes and may not be relied upon by you for any other purpose, or relied upon or furnished to any other person, without our prior written consent.

Very truly yours,

This letter is being delivered to you as Representatives pursuant to Section 6(b)(3) of the Underwriting Agreement.

In the above capacity, we have examined the registration statement on Form S-3 (File No. 333-202413) pertaining to the Notes and certain other securities filed by the Company

V-7

under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”); the Company’s prospectus dated March 2, 2015 (the “Base Prospectus”), as supplemented by a preliminary prospectus supplement dated May 19, 2016 (the “Pricing Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Act, which, pursuant to Form S-3, incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2015, the Quarterly Report on Form 10-Q of the Company for the quarter ended March 31, 2016 and the Current Reports on Form 8-K of the Company dated January 5, 2016 (other than the information furnished pursuant to Item 7.01), February 2, 2016 (other than the information furnished pursuant to Item 2.02 and Item 7.01), April 1, 2016 (other than the information furnished pursuant to Item 7.01), April 4, 2016, April 14, 2016, April 26, 2016 (other than the information furnished pursuant to Item 2.02 and Item 7.01), May 5, 2016 and May 5, 2016 (together, the “Pricing Exchange Act Documents”); and a prospectus supplement dated May 19, 2016 (together with the Base Prospectus, the “Final Supplemented Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, which, pursuant to Form S-3, incorporates by reference the Pricing Exchange Act Documents and the Current Report on Form 8-K of the Company dated May 19, 2016 (the “Exchange Act Documents”), each as filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have also examined the free writing prospectus prepared by the Company and filed with the Commission on May 19, 2016 pursuant to Rule 433 of the Act (the “Permitted Free Writing Prospectus”). The documents listed in Schedule II to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

We have participated in various conferences with the Company, its counsel, its representatives and representatives of the independent public or certified public accountants of the Company at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraph 6 of our opinion to you related to the Indenture and the Notes dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:

(ii) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make

No 2018 Notes shall be authenticated and delivered in excess of the principal amount as so increased except as provided by Sections 203, 303, 304, 907 or 1107 of the Original Indenture. The 2018 Notes shall be issued in fully registered form.

The 2018 Notes shall be issued in the form of one or more Global Securities in substantially the form set out in Exhibit A hereto. The Depositary with respect to the 2018 Notes shall be The Depository Trust Company.

“Comparable Treasury Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations or (ii) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Interest Payment Dates” means January 1 and July 1 of each year, commencing January 1, 2017.

“Original Issue Date” means May 24, 2016.

SECTION 103. Payment of Principal and Interest . The principal of the 2018 Notes shall be due at Stated Maturity (unless earlier redeemed). The unpaid principal amount of the 2018 Notes shall bear interest at the rate of 1.55% per annum until paid or duly provided for. Interest shall be paid semiannually in arrears on each Interest Payment Date to the Person in whose name the 2018 Notes are registered at the close of business on the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity or on a Redemption Date as provided herein will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the 2018 Notes are registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of the 2018 Notes not less than ten (10) days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the 2018 Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a 2018 Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of Holders of such Global Security shall be exercised only through the Depositary.

Subject to the procedures of the Depositary, a Global Security shall be exchangeable for 2018 Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Company, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the 2018 Notes. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for 2018 Notes registered in such names as the Depositary shall direct.

Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The rights of Holders of such Global Security shall be exercised only through the Depositary.

Subject to the procedures of the Depositary, a Global Security shall be exchangeable for 2019 Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Company, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the 2019 Notes.
