Ladies and Gentlemen:

Citigroup Inc., a corporation organized under the laws of Delaware (the “Company”), proposes, upon the terms and conditions set forth herein, to issue and sell 1,000,000 depositary shares (the “Depositary Shares”), each representing a 1/25th interest in a share of perpetual 4.150% Fixed Rate Reset Noncumulative Preferred Stock, Series Y (the “Preferred Stock”), of the Company (the “Securities”), to the several Underwriters named in Schedule I hereto (the “Underwriters”), for whom you (the “Representative”) are acting as representative. The Preferred Stock shall have the rights, powers and preferences set forth in the certificate of designations to be dated October 26, 2021 relating thereto (the “Certificate of Designations”). The shares of Preferred Stock represented by the Securities are to be deposited by the Company against delivery of depositary receipts evidencing the Securities (the “Depositary Receipts”) that are to be issued by Computershare Inc. and its wholly-owned subsidiary, Computershare Trust Company, N.A., as Depositary (together, the “Depositary”), under a Deposit Agreement, to be dated as of October 27, 2021 (the “Deposit Agreement”), among the Company, the Depositary and the holders from time to time of the Depositary Receipts issued thereunder.

The Company wishes to confirm as follows its agreement with you and the other several Underwriters named in Schedule I on whose behalf you are acting, in connection with the several purchases of the Securities by the Underwriters. To the extent there are no additional Underwriters named in Schedule I other than you, the term Representative as used herein shall mean you, as Underwriter, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires. Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final

Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 21 hereof.

1.    Registration Statement and Prospectus. The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission a shelf registration statement, as defined in Rule 405 (File No. 333-255302) on Form S-3, for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including all amendments thereto filed prior to the Execution Time, have become effective. The Company has filed with the Commission pursuant to Rule 424(b), a base prospectus related to the Securities, which has been previously furnished to you. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more Preliminary Prospectus relating to the Securities, each of which has previously been furnished to you. The Company will file with the Commission a Final Prospectus relating to the Securities in accordance with Rule 424(b). As filed, such Final Prospectus shall contain all information required by the Act and the rules thereunder, and, except to the extent the Representative shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

2.    Agreements to Sell and Purchase.

(a)    The Company hereby agrees, subject to all the terms and conditions set forth herein, to issue and sell to each Underwriter and, upon the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions set forth herein each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of $985 per Security, the number of Securities set forth opposite the name of such Underwriter in Schedule I hereto (or such number of Securities increased as set forth in Section 11 hereof).

3.    Offering by Underwriters. It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Disclosure Package and the Final Prospectus.

2

4.    Delivery of the Securities and Payment Therefor.

(a)    Delivery to the Underwriters of, and payment for, the Securities shall be made at or around 9:00 a.m., New York City time, on October 27, 2021 (the “Closing Date”). The Closing Date may be varied by agreement between you and the Company.

(b)    Delivery of the Securities shall be made to the Representative for the respective accounts of the several Underwriters against payment by the several Underwriters directly or through the Representative of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representative shall otherwise instruct.

(c)    It is understood that the Representative, acting individually and not in a representative capacity, may (but shall not be obligated to) make payment to the Company on behalf of any other Underwriter for Securities to be purchased by such Underwriter. Any such payment by the Representative shall not relieve any such Underwriter of any of its obligations hereunder.

5.    Agreements of the Company. The Company agrees with the several Underwriters that:

(a)    Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement to any Preliminary Prospectus or the Final Prospectus unless the Company has furnished the Representative a copy for their review prior to filing and will not file any such proposed amendment or supplement to which they reasonably object. The Company will cause the Final Prospectus, properly completed, and any supplement thereto, to be filed in a form acceptable to the Representative with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representative of such timely filing. The Company will promptly advise the Representative (i) when the Final Prospectus, and any supplement thereto, shall have been filed with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

3

(b)    The Company will prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof, in a form acceptable to you (the “Final Term Sheet”) and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(c)    If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Company will (i) notify promptly the Representative so that any use of the Disclosure Package may cease until it is amended or supplemented, (ii) amend or supplement the Disclosure Package to correct such statement or omission, and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(d)    If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company will (i) notify promptly the Representative of such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to the Representative in such quantities as the Representative may reasonably request.

(e)    As soon as practicable, the Company will make generally available to its security holders and to the Representative a consolidated earnings statement or statements of the Company and its subsidiaries, which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(f)    Upon request, the Company will furnish to the Representative and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of any Preliminary Prospectus, the Final Prospectus and any Issuer Free Writing Prospectus and any supplement thereto as the Representative may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering that are required to be prepared, furnished or delivered by the Company.

4

(g)    The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions within the United States as the Representative may reasonably designate, will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(h)    (i) The Company agrees that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Representative, and (ii) each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than the Final Term Sheet described above or other free writing prospectuses containing solely a description of the final terms of the Securities and the offering thereof. Any such free writing prospectus consented to by the Representative or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (1) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (2) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(i)    During the period beginning on the date hereof and continuing to and including the Closing Date, the Company will not, without the prior written consent of the Representative, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any preferred securities, any preferred stock or any other securities of the Company, including any backup undertaking of such preferred stock or other securities, in each case that are substantially similar to the Preferred Stock, or any securities convertible into or exchangeable for the preferred stock or such substantially similar securities of the Company, except for the offering of the Securities.

(j)    The Company will comply with all applicable securities and other laws, rules and regulations, including, without limitation, the Sarbanes Oxley Act of 2002, and use its best efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes Oxley Act of 2002.

(k)    The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange

5

Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities, except that the Company makes no agreement as to the activities of any Underwriter.

6.    Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, each Underwriter that:

(a)    On each Effective Date, the Registration Statement did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date, the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; on the date of any filing pursuant to Rule 424(b) and on the Closing Date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 7 hereof.

6

(f)    The holders of outstanding shares of capital stock of the Company are not entitled to preemptive or other rights to subscribe for the Securities or the underlying shares of Preferred Stock; and, except as set forth in the Disclosure Package and the Final Prospectus, no options, warrants or other rights to purchase, agreements or other obligations to issue, or rights to convert any obligations into or exchange any securities for, shares of capital stock of or ownership interests in the Company are outstanding.

(g)    As of the Execution Time, the Disclosure Package does 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 the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 7 hereof.

(i)    Neither any Issuer Free Writing Prospectus nor the Final Term Sheet includes any information that conflicts with the information contained in the Registration Statement, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus nor the Final Term Sheet based upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 7 hereof.

(j)    The interactive data in the eXtensible Business Reporting Language (“XBRL”) included or incorporated by reference in the Registration Statement fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(k)    Any certificate signed by any officer of the Company and delivered to the Representative or counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Underwriter.

(l)    Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer or employee of the Company or any of its subsidiaries has, as far as the Company and its subsidiaries are aware, breached or violated in any material way any applicable anti-bribery or anti-corruption laws or regulations, including the Foreign Corrupt

7

Practices Act of 1977 or the U.K. Bribery Act 2010, each as may be amended (“Anti-Bribery Laws”), and the Company and its subsidiaries have instituted and maintain policies and procedures reasonably designed to achieve compliance therewith. No part of the proceeds of the offering of the Securities will be used in violation of the Foreign Corrupt Practices Act of 1977 or the U.K. Bribery Act 2010, each as may be amended.

(m)    The Company and its subsidiaries have and will continue to maintain policies and procedures reasonably designed to achieve compliance with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder (collectively, the “Money Laundering Laws”).

(n)    Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer or employee of the Company or any of its subsidiaries (i) is, or is 50% or more owned by, an individual or entity that is currently the subject of any sanctions administered or imposed by the United States (including any administered or enforced by the Office of Foreign Assets Control of the U.S. Treasury Department or the U.S. Department of State), the United Nations Security Council, the European Union, or the United Kingdom (including sanctions administered or controlled by Her Majesty’s Treasury) or other relevant sanctions authority (collectively, “Sanctions”) or (ii) is located, organized or resident in a country or territory that is the subject of Sanctions that broadly prohibit dealings with that country or territory or (iii) will use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person to fund any activities or business with any individual or entity, or in any country or territory that, at the time of such funding, is the subject of Sanctions, except to the extent permissible under the Sanctions.

7.    Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange 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 Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

8

(b)    Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representative specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have. The Company acknowledges that the statements (i) set forth in the last paragraph of the cover page regarding delivery of the Securities and (ii) under the heading “Underwriting,” (1) the list of Underwriters and their respective participation in the sale of the Securities, (2) the sentences related to concessions and reallowances and (3) the paragraphs related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Prospectus, the Final Prospectus and any Issuer Free Writing Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Final Prospectus and any Issuer Free Writing Prospectus.

(c)    Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (1) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (2) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (3) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (4) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties

9

are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d)    In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. In no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

8.    Conditions of the Underwriters’ Obligations. The obligations of the several Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time, the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:
