CITIGROUP INC.
EMPLOYEE OPTION GRANT AGREEMENT
APPENDIX

        This Appendix constitutes part of the Employee Option Grant Agreement
(the "Agreement") and is applicable to the Executive Option Grant Program award
summarized on the first page of this Agreement. This Appendix is part of the
Agreement and sets forth the terms and conditions and other information
applicable to the non-qualified stock option (the "Option"), granted to
Participant under the Program, as described in the Award Summary on page 1. All
Options are denominated in shares of Citigroup common stock, par value $.01 per
share (referred to herein as "shares" or "Citigroup stock"). The "Company", for
purposes of this Agreement, shall mean Citigroup and its subsidiaries that
participate in the Program, except where provided otherwise herein.

        1.    Terms and Conditions.    The terms, conditions, and restrictions
of the Option are set forth below. Certain of these provisions, along with other
important information, are summarized in the Executive Option Grant Program
prospectus dated February 14, 2011 (the "Prospectus"), and any applicable
prospectus supplement that may be published from time to time. The terms,
conditions, and restrictions of the Option include, but are not limited to,
provisions relating to amendment, vesting, and cancellation of the Option,
restrictions on the transfer of the Option, and additional restrictions that may
be imposed on the Option pursuant to Sections 4(j) and 4(k) of this Agreement,
as further described below.

        By accepting an Option, Participant acknowledges that he or she has read
and understands the Prospectus and the terms and conditions set forth in this
Appendix. Participant understands that this Option and all other incentive
awards are entirely discretionary and that no right to receive the Option, or
any incentive award, exists absent a prior written agreement to the contrary.

        Participant understands that the value that may be realized from the
Option, if any, is contingent and depends on the future market price of
Citigroup stock, among other factors, and that because equity awards are
discretionary, and intended to promote employee retention and stock ownership
and to align employees' interests with those of stockholders, equity awards are
subject to vesting conditions and will be canceled if such conditions are not
satisfied.

        Any monetary value assigned to the Option in any communication regarding
the Option is contingent, hypothetical, and for illustrative purposes only and
does not express or imply any promise or intent by the Company to deliver,
directly or indirectly, any certain or determinable cash value to Participant.
Receipt of an Option covered by this Agreement, or any other incentive award, is
neither an indication nor a guarantee that an incentive award of any type or
amount will be made in the future, and absent a written agreement to the
contrary, the Company is free to change its practices and policies regarding
incentive awards at any time in its sole discretion.

        Any actual, anticipated, or estimated financial benefit to Participant
from the Option is not and shall not be deemed to be a normal or an integral
part of Participant's regular or expected salary or compensation from employment
for any purposes, including, but not limited to, calculating any statutory,
common law or other employment-related payment to Participant, including any
severance, resignation, termination, redundancy, end-of-service, bonus,
long-service awards, pension, superannuation or retirement or welfare or similar
payments, benefits or entitlements, and in no event should be considered as
compensation for, or relating in any way to, past services for the Company.

        2.    Vesting.    If conditions to vesting are satisfied, the Option
will vest in the installment amounts and on the vesting dates set forth in the
Stock Option Grant Summary. Vesting in each case is subject to receipt of the
information necessary to make any required tax payments and confirmation by
Citigroup that all conditions to vesting have been satisfied.

2

--------------------------------------------------------------------------------

        Vesting is conditioned on Participant's continuous employment with the
Company up to and including the scheduled vesting date, unless otherwise
provided below, and subject to Section 4(j).

        3.    Exercise of Option.    Vested Option shares may be exercised in
whole or in part by Participant upon notice to the Company, together with
provision for payment of the grant price (as set forth in the Stock Option Grant
Summary). Such notice shall be given in the manner prescribed by Citigroup and
shall specify the date and method of exercise and the number of Option shares
that are being exercised. The currently available option exercise methods, which
are subject to change at any time, are described in the Prospectus. All stock
option exercises will be processed in accordance with the Citigroup Equity
Compensation administrative procedures and deadlines then in effect. If
Participant uses a broker-assisted exercise method that may be available from
time to time, Participant acknowledges and agrees that option proceeds from any
broker-assisted exercises will be net of applicable commissions and fees
associated with these transactions. The applicable commissions and fees will be
disclosed to Participant at or prior to the time of exercise or will be
available to Participant upon request. The laws of the country in which
Participant is working at the time of grant, vesting, and/or exercise of the
Option (including any rules or regulations governing securities, foreign
exchange, tax or labor matters), and Citigroup accounting or other policies,
whether dictated by such country's political or regulatory climate or otherwise,
may restrict or prohibit any one or more of the stock option exercise methods
described in the Prospectus; such restrictions may apply differently if
Participant is a resident or expatriate employee, and are subject to change at
any time. If the last day on which an Option may be exercised pursuant to any
provision of this Agreement is not a trading day on the New York Stock Exchange,
then the immediately preceding New York Stock Exchange trading day shall be the
last day on which an Option may be exercised. Under no circumstances may an
Option be exercised after the Option Expiration Date set forth in the Stock
Option Grant Summary (the "Option expiration date"). The Company is not
obligated to notify a Participant (or his or her estate or personal
representatives) that an Option is nearing expiration.

        4.    Continuous Employment and other Vesting and Post-Vesting
Conditions.    The vesting of the Option shares and the Participants right to
exercise Option shares is conditioned upon Participant's continuous employment
with the Company and/or subject to other conditions, as provided below.

        The vesting of Option shares and Participant's right to exercise Option
shares is conditioned upon Participant's continuous employment with the Company,
except as otherwise provided below.

        If Participant's employment with the Company terminates or is
interrupted for any reason described below, Participant's rights with respect to
the Option will be affected as indicated below. If Participant's employment with
the Company terminates for any reason not described below, the Option will be
canceled.

        (a)    Voluntary Resignation.    If Participant voluntarily terminates
his or her employment with the Company and at such time does not satisfy the
conditions of Section 4(i) below, vesting of Option shares will cease and all
unvested Option shares will be canceled on the date Participant's employment is
so terminated. Participant may exercise vested Option shares until the Option
expiration date.

        (b)    Disability.    Option shares will continue to vest on schedule
and may be exercised, subject to all other provisions of this Agreement, during
Participant's approved disability leave pursuant to a Company disability policy
(but not later than the Option expiration date). If Participant's disability
ends with Participant's termination of employment on account of the disability,
any unvested Option shares will vest immediately. Vested Option shares may be
exercised until the Option expiration date.

        (c)    Approved Personal Leave of Absence (Non-Statutory Leave).    

        (i)    Unvested Option shares will continue to vest on schedule and may
be exercised, subject to all other provisions of this Agreement, during the
first six months of an approved personal leave of absence, provided that
Participant's leave of absence was approved by management of

3

--------------------------------------------------------------------------------

Participant's business unit in accordance with the leave of absence policies
applicable to Participant (an "approved personal leave of absence"). Unvested
Option shares will be canceled as soon as the approved personal leave of absence
has exceeded six months, except as provided in paragraph (ii) below.

        (ii)   If Participant's employment terminates for any reason specified
elsewhere in this Section 4 during the first six months of an approved personal
leave of absence, the Award will be treated as described in the applicable
provision of this Section 4. If Participant meets the "Rule 75" as defined in
Section 4(i) before the approved personal leave of absence exceeds six months,
unvested shares will continue to vest on schedule, subject to all other
provisions of this agreement.

        (d)    Statutory Leave of Absence.    Unvested Option shares will
continue to vest on schedule and may be exercised, subject to all other
provisions of this agreement, during a leave of absence that is approved by
management of Participant's business unit, provided by applicable law and is
taken in accordance with such law and applicable Company policy (a "statutory
leave of absence"). If Participant meets the "Rule of 75" as defined in
Section 4(i) during a statutory leave of absence, unvested shares will continue
to vest on schedule, subject to all other provisions of this agreement.

        (e)    Death.    If Participant's employment terminates by reason of
Participant's death, any unvested Option shares will vest and vested Option
shares may be exercised only by the lawful representative of Participant's
estate until the Option expiration date.

        (f)    Involuntary Termination for Gross Misconduct.    Notwithstanding
any provisions of this Agreement to the contrary, if the Company terminates
Participant's employment because of Participant's "gross misconduct" (as defined
below), vesting of the Option, and the Participant's right to exercise vested
Option shares will cease on the date Participant's employment is so terminated;
all unvested and unexercised Option shares will be canceled as of date
Participant's employment is terminated, and Participant shall have no further
rights of any kind with respect to the Option. For purposes of this Agreement,
"gross misconduct" means any conduct that (i) is in competition with the
Company's business operations, (ii) that breaches any obligation that
Participant owes to the Company or Participant's duty of loyalty to the Company,
(iii) is materially injurious to the Company or (iv) is otherwise determined by
the Personnel and Compensation Committee of the Citigroup Board of Directors
(the "Committee"), in its sole discretion, to constitute gross misconduct. For
purposes of this Section 4(f), "Company" shall mean Citigroup and any of its
subsidiaries.

        (g)    Employment by Company Ends as a Result of a "Qualifying
Transaction."    If Participant is no longer employed by the Company as a direct
result of a "qualifying transaction" (as defined below), all unvested Option
shares will vest on the date Participant's employment status changes as a result
of the qualifying transaction. Vested Option shares may be exercised until the
Option expiration date. For these purposes, a "qualifying transaction" means any
one of the following events or combination of events:

        (i)    The stock or other equity interest in the Citigroup subsidiary
that employs Participant is sold or otherwise disposed of in a transaction that
results in Citigroup ceasing to control or own a significant equity interest in
the subsidiary. In these circumstances, Participant's employment by the Company
will end on the date Citigroup ceases to control or own a significant equity
interest in the subsidiary. For these purposes, the Committee will determine, in
its sole discretion, whether Citigroup ceases to control, or own a significant
equity interest in, a subsidiary.

        (ii)   Either (a) a sale or other disposition of assets comprising the
business unit to which Participant provides substantial services, or (b) the
transfer to an external service provider of Participant's job function in
connection with the Company's entering into a services agreement with the
external service provider, and (c) the involuntary termination of Participant's
employment

4

--------------------------------------------------------------------------------

by the Company other than for "gross misconduct" in connection with the sale or
other disposition of assets or the Company's entering into a services agreement
covering Participant's job function. In these circumstances, Participant will
not be eligible for the treatment described above if the Company determines that
Participant has rejected an employment opportunity with the buyer or external
services provider on terms and conditions that are comparable to the terms and
conditions of Participant's employment by the Company, and in such case
paragraph (h) (or other applicable paragraph) of this Section 4 will apply.

        (h)    Involuntary Termination Other than for Gross
Misconduct.    Unless paragraph (g) above applies, if Participant's employment
is terminated by the Company involuntarily other than for gross misconduct
including under a reduction in force or job discontinuance program, and
Participant has not met the "Rule of 75" as defined in Section 4(i), a prorated
portion of the unvested Option shares will immediately vest and any vested
Option shares may be exercised until the Option expiration date. The prorated
portion of unvested Option shares that vest in accordance with the preceding
sentence shall be calculated (1) by assuming that the portion of the Option
shares scheduled to vest on each different vesting date is a separate award, and
(2) for each separate award, by multiplying the number of unvested Option shares
that are subject to such separate award by a fraction, the numerator of which is
equal to the number of days the Participant was employed by the Company during
the vesting period applicable to such separate award and the denominator of
which is equal to the number of days in the entire vesting period applicable to
such separate award. For these purposes, the vesting period is the period of
time starting on and including the grant date and ending on and including the
applicable vesting date.

        (i)    Termination after meeting the "Rule of 75."    If Participant's
employment with the Company terminates for any reason other than involuntary
termination for "gross misconduct," and on or before such date Participant's age
plus full years of service with the Company equals at least 75 (the "Rule of
75"), then any unvested Option shares will vest on the date Participant's
employment terminates. Vested Option shares may be exercised until the Option
expiration date.

        (j)    Clawback; Misconduct; Error; Downturn in Performance or Failure
of Risk Management.    Any unvested shares subject to the Option and any vested
but unexercised Option shares will be canceled or forfeited if the Committee
determines that (1) Participant received the Option based on materially
inaccurate financial statements (which includes, but is not limited to,
statements of earnings, revenues, or gains) or any other materially inaccurate
performance metric criteria, (2) Participant knowingly engaged in providing
inaccurate information (including knowingly failing to timely correct inaccurate
information) relating to financial statements or performance metrics, or
(3) Participant materially violated any risk limits established or revised by
senior management, a business head and/or risk management, or any balance sheet
or working or regulatory capital guidance provided by a business head.

        (k)    One-Year Sale Restriction on Incremental Shares from Exercises
before February 14, 2016.    If Participant exercises the Option before the
fifth anniversary of the grant date (February 14, 2016), the shares issued after
covering the option cost (equal to the grant price, as set forth in the Stock
Option Grant Summary, times the number of option shares exercised), applicable
taxes, and any brokerage commission and fees ("incremental shares") will be
subject to a restriction on sale or transfer beginning on the exercise date and
ending one year thereafter. In the event of Participant's death, the sale
restriction imposed on Option shares will cease to apply and will not be imposed
on any shares that may be acquired by Participant's estate in a future exercise
of the Option.

        5.    Non-Transferability.    The Option and any sale-restricted
incremental shares relating to the Option may not be sold, pledged,
hypothecated, assigned, margined or otherwise transferred, other than by will or
the laws of descent and distribution, and no Option or interest or right therein
shall be subject to the debts, contracts or engagements of Participant or his or
her successors in interest or shall

5

--------------------------------------------------------------------------------

be subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law, by judgment, lien, levy, attachment,
garnishment or any other legal or equitable proceedings (including bankruptcy or
divorce), and any attempted disposition thereof shall be null and void, of no
effect, and not binding on the Company in any way. Participant agrees that any
purported transfer shall be null and void, and shall constitute a breach of this
Agreement causing damage to the Company for which the remedy shall be a
cancelation of the Option. During Participant's lifetime, all rights with
respect to the Option shall be exercisable only by Participant, and any and all
payments in respect of the Option shall be to Participant only. The Company
shall be under no obligation to entertain, investigate, respect, preserve,
protect or enforce any actual or purported rights or interests asserted by any
creditor of Participant or any other third party in the Option, and Participant
agrees to take all reasonable measures to protect the Company against any such
claims being asserted in respect of Participant's Option and to reimburse the
Company for any and all reasonable expenses it incurs defending against or
complying with any such third-party claims if Participant could have reasonably
acted to prevent such claims from being asserted against the Company.

        6.    Stockholder Rights.    Participant shall have no rights as a
stockholder of Citigroup over any shares covered by an Option, unless and until
shares are distributed to Participant in connection with an Option exercise.

        7.    Right of Set Off.    Participant agrees that the Company may, to
the extent determined by the Company to be permitted by applicable law, retain
for itself funds or securities otherwise payable to Participant pursuant to this
Option or any award under any equity award program administered by Citigroup to
offset any amounts paid by the Company to a third party pursuant to any award,
judgment, or settlement of a complaint, arbitration, or lawsuit of which
Participant was the subject; to satisfy any obligation or debt that Participant
owes the Company or its affiliates; or in the event any equity award is canceled
pursuant to its terms. The Company may not retain such funds or securities and
set off such obligations or liabilities, as described above, until such time as
they would otherwise be distributable to Participant in accordance with the
applicable award terms.

        8.    Consent to Electronic Delivery.    In lieu of receiving documents
in paper format, Participant hereby agrees, to the fullest extent permitted by
law, to accept electronic delivery of any documents that Citigroup may be
required to deliver (including, but not limited to, prospectuses, prospectus
supplements, grant or award notifications and agreements, account statements,
annual and quarterly reports, and all other forms or communications) in
connection with the Option(s) covered by this Agreement and any other prior or
future incentive award or program made or offered by Citigroup or its
predecessors or successors. Electronic delivery of a document to Participant may
be via a Company e-mail system or by reference to a location on a Company
intranet or secure internet site to which Participant has access.

        9.    Plan Administration.    The Option described in this Agreement has
been granted subject to the terms of the Plan. The shares deliverable to
Participant upon the exercise of an Option will be from the shares available for
grant pursuant to the terms of the Plan.

        10.    Adjustments.    In the event of any change in Citigroup's capital
structure on account of (i) any extraordinary dividend, stock dividend, stock
split, reverse stock split or any similar equity restructuring; or (ii) any
combination or exchange of equity securities, merger, consolidation,
recapitalization, reorganization, divestiture or other distribution (other than
ordinary cash dividends) of assets to stockholders, or any other similar event
affecting Citigroup's capital structure, to the extent necessary to prevent the
enlargement or diminution of the rights of Participants, the Committee shall
make such appropriate equitable adjustments as may be permitted by the terms of
the Plan and applicable law, to the number or kind of shares subject to an
Option and/or the grant price applicable to an Option. All such adjustments
shall conform to the requirements of Section 409A of the Internal

6

--------------------------------------------------------------------------------

Revenue Code of 1986, as amended (the "Code"), to the extent applicable, and
with respect to Options intended to qualify as "performance-based compensation"
under Section 162(m) of the Code, such adjustments or substitutions shall be
made only to the extent that the Committee determines that such adjustments or
substitutions may be made without causing the Company to be denied a tax
deduction on account of Section 162(m) of the Code. Citigroup shall give each
Participant notice of an adjustment hereunder and, upon notice, such adjustment
shall be conclusive and binding for all purposes. Notwithstanding the foregoing,
the Committee may, in its discretion, decline to adjust any Option granted to a
Participant, if it determines that such adjustment would violate applicable law
or result in adverse tax consequences to the Participant or the Company, and
neither the Committee nor Citigroup shall be bound to compensate any Participant
for any such adjustment not made, nor shall they be liable to Participant for
any additional personal tax or other consequences of any adjustments that are
made to an Option.

        11.    Taxes and Tax Residency Status.    By accepting the Option,
Participant agrees to pay all applicable income taxes (or hypothetical tax, if
Participant is subject to tax equalization or tax protection pursuant to a
Citigroup Expatriate policy) and file all required tax returns in all
jurisdictions where Participant is subject to tax and/or an income tax filing
requirement. To assist Citigroup in achieving full compliance with its
obligations under the laws of all relevant taxing jurisdictions, Participant
agrees to keep complete and accurate records of his or her income tax residency
status and the number and location of workdays outside his or her country of
income tax residency from the date of an Option grant until the later of the
date of its last exercise or the subsequent sale of any shares upon any exercise
of the Option. By accepting the Option, Participant also agrees to provide, upon
request, information about his or her tax residency status to Citigroup during
such period. Participant will be responsible for any income tax due, including
penalties and interest, arising from any misstatement by Participant regarding
such information.

        12.    Entire Agreement; No Right to Employment.    The Prospectus and
the Agreement constitute the entire understanding between the Company and
Participant regarding the Option and supersede all previous written, oral, or
implied understandings between the parties hereto about the subject matter
hereof, including any written or electronic agreement, election form or other
communication to, from or between Participant and the Company. Nothing contained
herein, in the Plan, the Prospectus, or in any prospectus supplement or any
other communication about the Option shall confer upon Participant any rights to
continued employment or employment in any particular position, at any specific
rate of compensation, or for any particular period of time.

        13.    Amendment.    The Committee may in, its sole discretion, modify,
amend, terminate or suspend the Option or the Program at any time, except that
no termination, suspension, modification or amendment of the Option or the
Program shall (i) cause the Option or the Program to become subject to, or
violate, Section 409A of the Code, or (ii) adversely affect Participant's rights
with respect to the Option, as determined by the Committee, without
Participant's written consent.

        14.    Compliance with Regulatory Requirements.    Notwithstanding any
provision of this Agreement to the contrary, the Option will be subject to any
limitations, adjustments or clawback provisions applicable to Participant to the
extent required under (a) the Emergency Economic Stabilization Act of 2008, as
amended, and any applicable rules or regulations thereunder, (b) any agreement
entered into between the Company and the United States Treasury Department in
connection with the Company's participation in, the Troubled Asset Relief
Program or the Exchange Agreement dated June 9, 2009, between the Company and
the United States Treasury Department and the Federal Deposit Insurance
Corporation, or (c) any policy implemented at any time by the Company in its
discretion to (i) comply with any other legal, regulatory or governmental
requirements, directions, supervisory comments, guidance or promulgations
specifically including but not limited to guidance on remuneration practices or
sound incentive compensation practices promulgated by any U.S. or non-U.S.
governmental agency or authority, (ii) comply with the listing requirements of
any stock exchange on

7

--------------------------------------------------------------------------------

which the Company's common stock is traded or (iii) comply with or enable the
Company to qualify for any government loan, subsidy, investment or other
program.

        15.    Arbitration; Conflict; Governing Law.    Any disputes related to
the Option shall be resolved by arbitration in accordance with the Company's
arbitration policies. In the absence of an effective arbitration policy,
Participant understands and agrees that any dispute related to an Option shall
be submitted to arbitration in accordance with the rules of the American
Arbitration Association, if so elected by the Company in its sole discretion. In
the event of a conflict between the Prospectus and this Agreement, this
Agreement shall control. In the event of a conflict between this Agreement and
the Plan the Plan shall control. This Agreement shall be governed by the laws of
the State of New York (regardless of conflict of laws principles) as to all
matters, including, but not limited to, the construction, application, validity
and administration of the Program.

        16.    Disclosure Regarding Use of Personal Information and
Participant's Consent.    

        (a)    Definition and Use of "Personal Information."    In connection
with the grant of this Option, and any other award under the Program or any
other equity award program, and the implementation and administration of any
such program, including, without limitation, Participant's actual participation,
or consideration by the Company for potential future participation, in any
program at any time, it is or may become necessary for the Company to collect,
transfer, use, and hold certain personal information regarding Participant in
and/or outside of Participant's home country.

electronically or otherwise, may be in connection with the Company's internal
administration of its equity award programs, or in connection with tax or other
governmental and regulatory compliance activities directly or indirectly related
to an equity award program. For such purposes only, personal information may be
used by third parties retained by the Company to assist with the administration
and compliance activities of its equity award programs, and may be transferred
by the company that employs (or any company that has employed) Participant from
Participant's home country to other Citigroup entities and third parties located
in the United States and in other countries. Specifically, those parties that
may have access to Participant's information for the purposes described herein
include, but are not limited to, (i) human resources personnel responsible for

award coordinators, and global coordinators located in the United States;

information systems that support the equity award programs); and (vi) internal
and external legal, tax and accounting advisors (but only to the extent
necessary for them to advise the Company on compliance and other issues
affecting the equity award programs in their respective fields of expertise). At
all times, Company personnel and third parties will be obligated to maintain the
confidentiality of Participant's personal information except to the extent the
Company is required to provide such information to governmental agencies or
other parties. Such action will always be undertaken only in accordance with
applicable law.

GUARANTEE THAT ANY AWARD WILL BE MADE); AND (II) TO THE USE, TRANSFER,
PROCESSING AND STORAGE, ELECTRONICALLY OR OTHERWISE, OF HIS/HER PERSONAL
INFORMATION, AS SUCH USE HAS OCCURRED TO DATE, AND AS SUCH USE MAY OCCUR IN THE
