EXHIBIT 10.2 2016 Year-End Version (UK) KCG HOLDINGS, INC. DEFERRED CASH AWARD AGREEMENT

The Company hereby grants you the Deferred Cash Award, which constitutes an unfunded and unsecured promise to pay to you, subject to the terms and conditions of this Agreement, the amount set forth above, plus any accrued interest as described in Section 4, on the date or dates provided in this Agreement.

Except as otherwise provided in this Agreement, your Deferred Cash Award is unvested, which means that it is subject to a condition that you remain actively employed by the Company and that you comply with the Applicable Restrictive Covenants, in each case, through the applicable Vesting Date in order for you to receive payment in respect thereof. The “Restricted Vesting Period” is the period from the Grant Date until the applicable Vesting Date during which these vesting conditions apply.

Except as otherwise provided in this Agreement, the Deferred Cash Award will be paid to you in three substantially equal installments (before giving effect to the additional amount credited to such award under Section 4) reasonably promptly (but no more than 30 days) after each Vesting Date. Until such payment, you have only the rights of a general unsecured creditor of the Company.

During the Restricted Vesting Period, the unpaid portion of your Deferred Cash Award will accrue interest at the rate then in effect (the “Discretionary Interest Rate”) as determined by the Compensation Committee of the Board of Directors of the Company

Except as otherwise provided for in your Employment Agreement, if applicable:

if your employment with, or provision of services to, the Company or any of its Affiliates is terminated by the Company or any of its Affiliates without Cause, or otherwise terminates on account of your death or Disability, the vesting conditions applicable to the Deferred Cash Award will lapse and the unpaid portion of the Deferred Cash Award will be paid to you (or the representative of your estate) reasonably promptly (but no more than 30 days) thereafter, together with any interest credited to your Deferred Cash Award under Section 4 through the date of your termination;

if your employment with, or provision of services to, the Company or any of its Affiliates is terminated for Cause, all of your rights to your Deferred Cash Award will terminate and your Deferred Cash Award will be cancelled without any payment to you;

if your employment with, or provision of services to, the Company or any of its Affiliates terminates for any reason other than as set forth in Sections 5(a) and 5(b), your Deferred Cash Award will continue to vest as if your employment with the Company or any of its Affiliates had continued, subject to Section 6 which will continue to apply through the remainder of the Restricted Vesting Period.

If during the Restricted Vesting Period, you breach or otherwise take any action that is prohibited by an Applicable Restrictive Covenant, all of your rights to your Deferred Cash Award will terminate and your Deferred Cash Award will be cancelled without any payment to you. You understand that your eligibility for the continued vesting of your Deferred Cash Award pursuant to Section 5(c) is contingent on your ongoing compliance with the Applicable Restrictive Covenants for the duration of the Restricted Vesting Period regardless of the length of the protected period or similar restrictive covenant period which you are required to comply under an Employment Agreement, award agreement or other agreement you have with the Company.

You acknowledge that as a condition to accepting payment of your Deferred Cash Award, you may be required to certify to the Company, in the form and manner determined by the Company in its sole discretion, that you have complied with all terms and conditions of this Agreement, including the Applicable Restrictive Covenants. You understand and agree that:

if the Company determines, in its sole discretion, that you have failed to comply with all terms and conditions of this Agreement, all of your rights to your Deferred Cash Award will terminate and your Deferred Cash Award will be cancelled without any payment to you; and

(i) your address on file with the Company at the time any certification is required will be deemed to be your current address, (ii) it is your responsibility to inform the Company of any changes to your address to ensure timely receipt of the certification materials, (iii) you are responsible for contacting the Company to obtain such certification materials if not received and (iv) your failure to return properly completed certification materials by the specified deadline (which includes your failure to timely return the completed certification because you did not provide the Company with updated contact information) will result in the cancellation of your Deferred Cash Award without any payment to you. For the avoidance of doubt, references in this Section 7(b) to your address are inclusive of your email address and references to your receipt and return of certification materials are inclusive of such actions taken by means of electronic communication.

If at any time within two (2) years after a Vesting Date (a “realization event”), you (a) are terminated for Cause, (b) engage in or have engaged in any activity that is a violation of an Applicable Restrictive Covenant during the protected period or similar restrictive covenant period, (c) violate or have violated any confidentiality or proprietary information obligation you owe to the Company (including, but not limited to, the confidentiality or proprietary information obligations in any non-compete agreement, Employment Agreement, employee handbook, non-disclosure agreement, Code of Business Conduct or Ethics, equity award agreement or any other agreement signed by you that contains such obligations), and/or (d) engage in or have engaged in any act of fraud against the Company, then you hereby agree that the amount of the Deferred Cash Award that became vested at the realization event shall be paid by you to the Company upon notice from the Company (the “Repayment Amount”). The Repayment Amount shall be determined on a gross basis, without reduction for any taxes incurred, as of the date of the realization event. The Company shall have the right to offset the Repayment Amount against any amounts otherwise owed to you by the Company (whether as wages, vacation pay or pursuant to any benefit plan or other compensatory arrangement) to the extent permissible under applicable law, including Section 409A. Additionally, the Deferred Cash Award is subject to the Company’s Compensation Recoupment Policy, if applicable to you, which can cause the forfeiture of the Deferred Cash Award.

Without limiting the application of Sections 12 and 13, in the event of a Change-In-Control the Committee reserves the right, in its sole discretion, to accelerate the vesting of the Deferred Cash Award, but shall have no obligation to take any such action. In the absence of any such action under this Section 9, the Deferred Cash Award shall continue in effect in accordance with its terms. Notwithstanding anything to the contrary in Section 5, in the event that you cease to be an Employee (including by reason of the Company’s sale or divestiture of a business unit or otherwise where such transaction is not a Change-In-Control), the Committee shall, in its sole discretion, have the authority to provide that (A) the vesting restrictions applicable to any unvested portion of your Deferred Cash Award shall lapse upon the effective time of completion of such sale or divestiture or (B) (i) any unvested portion of your Deferred Cash Award not be forfeited upon such termination and (ii) you continue to vest in the Deferred Cash Award in

For the purposes of this Section 10, “Taxable Event” shall mean any event or circumstance that gives rise to a liability of or for the Grantee to pay income tax and National Insurance Contributions (“NICs”) or either of them (or their equivalents in any jurisdiction) in respect of or in connection with: (i) this Agreement, including the vesting of, or lapse of restrictions on, or payment of, any or all of the Deferred Cash Award, its assignment or surrender for consideration, or the receipt of any benefit in connection with it; (ii) any cash or other assets earmarked or held to satisfy this Agreement; and (iii) any amount due under PAYE in respect of events within (i) to (ii) above including any failure by you to make good such an amount within the time limit specified in section 222 of the Income Tax (Earnings and Pensions) Act 2003.

For the purposes of this Section 10, “Tax Liability” shall mean the total of any income tax and primary class 1 (employee) NICs (or their equivalents in any jurisdiction) that your employer (or former employer) is liable to account for (or reasonably believes it is liable to account for) as a result of any Taxable Event.

You agree that the Company may deduct and withhold an amount equal to any Tax Liability or any part of it from all amounts paid in respect of or in connection with the Deferred Cash Award upon the vesting of, or lapse of restrictions on, or payment of, any or all of the Deferred Cash Award.

You also agree that the Company (or your employer or former employer) may withhold an amount equal to any Tax Liability or any part of it from any other amounts payable to you (whether wages, vacation pay or pursuant to any benefit plan or other compensatory arrangement), in each case if for any reason insufficient amounts are withheld under Section 10(c) and you do not fulfil you obligations under Section 10(d) above within a reasonable period (as determined by the Committee in its absolute discretion) after the relevant Tax Liability has arisen.

Except with the consent of the Committee, you may not sell, pledge, hypothecate, assign, transfer or otherwise encumber the Deferred Cash Award, other than by will or the laws of descent and distribution. This prohibition includes any assignment or other transfer that purports to occur by operation of law or otherwise. During your lifetime, payments relating to the Deferred Cash Award will be made only to you and any attempt to sell, pledge, hypothecate, assign, transfer or otherwise encumber the Deferred Cash Award shall be void.

All matters with respect to the Deferred Cash Award will be determined by the Committee or its designee. The Committee has the authority and discretion to select those persons who shall receive Deferred Cash Awards, to determine the time or times of receipt, to establish the terms, conditions, performance criteria, restrictions or other provisions of the Deferred Cash Awards, and, subject to the restrictions of Section 14, to modify, amend or terminate the Deferred Cash Awards. The Committee’s determinations regarding Deferred Cash Awards (including, without limitation, the amount and timing of such awards, the terms and provision of such awards and the agreements evidencing the same) need not be uniform and may be made by it selectively among individuals who receive, or are eligible to receive Deferred Cash Awards. Except to the extent prohibited by applicable law, the Committee may delegate to any person or persons all or any part of its responsibilities and powers as set forth in this Agreement, and may revoke such delegation at any time.

The Committee is authorized to establish, amend and rescind such rules and regulations as it deems necessary or advisable for the proper administration of Deferred Cash Awards and to take such other action in connection with or in relation to such Deferred Cash Awards as it deems necessary or advisable. Each action and determination made by the Committee with respect to the Deferred Cash Award will be final and conclusive. No employee of the Company or any member of the Board will be personally liable for any action, determination or interpretation made in good faith with respect to this Agreement or the Deferred Cash Award granted hereto.

The Committee may at any time terminate, modify or amend the Deferred Cash Award in such respects as it shall deem advisable; provided, however; that no termination, modification or amendment of any outstanding Deferred Cash Award may, without your consent, adversely affect your rights with respect to the outstanding Deferred Cash Award.

This Agreement does not constitute a contract of employment, nor does it give you the right to be retained in the employ of the Company or any Affiliate, or the right to continue to provide services to the Company or any Affiliate, in each case, for any particular period or on any particular basis of compensation. Nothing contained in this Agreement, and no action of the Company or the Committee with respect to this Agreement, will interfere in any way with the right of the Company or an Affiliate to terminate your employment at any time, for any reason or for no reason.

By executing this Agreement and acknowledging the terms and conditions set forth herein, you will be deemed to have agreed that this Deferred Cash Award is special incentive compensation that will not be taken into account, in any manner, as salary, compensation or bonus in determining the amount of any payment under any health and welfare, pension, retirement or other employee benefit plan, program or policy of the Company or any Affiliate.

You will not, by reason of this Agreement, acquire any right in or title to any assets, funds or property of the Company or any Affiliate, including, without limitation, any specific funds, assets or other property which the Company or any Affiliate in its sole discretion may set aside in anticipation of a liability under this Agreement. You will only have a contractual right to the amounts, if any, payable under this Agreement, unsecured by any assets of the Company or any Affiliate, and nothing contained in this Agreement shall constitute a guarantee that the assets of the Company or any Affiliate shall be sufficient to pay any benefits to any person.

The Company and you hereby irrevocably submit to the exclusive jurisdiction of any state or federal court of appropriate jurisdiction located in New York, New York over any suit, action or proceeding arising out of or relating to or concerning this Agreement that is not otherwise arbitrated or resolved according to Section 19.

The Company and you acknowledge that the forum designated by this section has a reasonable relation to this Agreement and to the relationship between the Company and you. Notwithstanding the foregoing, nothing herein shall preclude the Company from bringing any action or proceeding in any other court for the purpose of enforcing the provisions of this section.

The agreement by the Company and you as to forum is independent of the law that may be applied in the action, and the Company and you (i) agree to such forum even if the forum may under applicable law choose to apply non-forum law, (ii) hereby waive, to the fullest extent permitted by applicable law, any objection which the Company or you now or hereafter may have to personal jurisdiction or to the laying of venue of any such suit, action or proceeding in any court referred to in this section, (iii) undertake not to commence any suit, action or proceeding arising out of or relating to or concerning this Agreement in any forum other than the forum described in this section, and (iv) agree that, to the fullest extent permitted by applicable law, a final and non-appealable judgment in any such suit, action or proceeding in any such court shall be conclusive and binding upon the Company and you.

You hereby irrevocably appoint the General Counsel of the Company as your agent for service of process in connection with any action, suit or proceeding arising out of or relating to or concerning this Agreement that is not otherwise arbitrated or resolved according to Section 19.

You agree to keep confidential the existence of, and any information concerning, a dispute, controversy or claim described in this section, except that you may disclose information concerning such dispute, controversy or claim to the arbitrator or court that is considering such dispute, controversy or claim or to your legal counsel (provided that such counsel agrees not to disclose any such information except as necessary to the prosecution or defense of the dispute, controversy or claim).

Subject to the provisions of Section 18 above, any dispute, controversy or claim between the Company and you, arising out of or relating to or concerning this Agreement will be finally settled by binding arbitration in New York, New York before, and in accordance with the rules then obtaining of, the Financial Industry Regulatory Authority (“FINRA”) or, if FINRA declines to arbitrate the matter (or if the matter otherwise is not arbitrable by it), the American Arbitration Association (the “AAA”) in accordance with the commercial arbitration rules of the AAA. Prior to arbitration, all claims maintained by you must first be submitted to the Committee in accordance with claims procedures determined by the Committee.

If you attempt to have any dispute that arises out of or relates to this Agreement resolved in any manner that is not provided for by Sections 18 and 19 above, then (i) any outstanding portion of the Deferred Cash Award (whether vested or unvested) shall be forfeited and (ii) any amounts paid in respect of the Deferred Cash Award shall be repaid by you to the Company upon notice from the Company in the manner set forth in Section 8.

The obligation of the Company to make payments in respect of the Deferred Cash Award granted under this Agreement is specifically subject to all provisions of this Agreement, and all applicable laws, rules, regulations and governmental approvals.

The grant of the Deferred Cash Award is not enforceable until this Agreement has been signed by the Company and acknowledged by you. By acknowledging this Agreement, you shall be deemed to have accepted and consented to any action taken under this Agreement by the Committee, the Board or any of their delegates.

No change or modification of this Agreement shall be valid unless it is in writing and signed by the parties hereto.

Any notice by you to the Company hereunder shall be in writing and shall be deemed duly given only upon receipt thereof by the Company at its principal offices. Any notice by the Company to you shall be in writing and shall be deemed duly given if mailed to you at the address on file with the Company.

The grant of Deferred Cash Awards shall not be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem advisable, and such arrangements may be either generally applicable or applicable only in specific cases.

The validity and construction of this Agreement shall be governed by the laws of the State of Delaware, without regard to the conflicts of law principles thereof.

This Agreement sets forth all of the promises, agreements, conditions, understandings, warranties and representations between the parties hereto regarding the Deferred Cash Award, and there are no promises, agreements, conditions, understandings, warranties or representations, oral or written, express or implied, between them regarding the Deferred Cash Award other than as set forth herein or therein.

The provisions of this Section 28 apply to only those Grantees who are U.S. taxpayers. The intent of the parties is that payments and benefits under this Agreement comply with Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and be administered consistent with such intent. Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, you shall not be considered to have terminated employment with the Company for purposes of this Agreement and no payment shall be due to you under Section 5(a) of this Agreement until you would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A. Any payments that are due within the “short term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in this Agreement, to the extent that any amounts are payable upon a “separation from service” and such payment would result in the imposition of any additional tax and penalties imposed under Section 409A, the payment of such amounts shall instead be made on the first business day after the date that is six (6) months following such separation from service (or death, if earlier) to the extent any such delay would avoid the imposition of such tax or penalty. In addition, each amount to be paid or benefit to be provided to you pursuant to this Agreement, which constitutes deferred compensation subject to Section 409A, shall be construed as a separate identified payment for purposes of Section 409A.

As used in this Agreement, “the Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets, whether direct or indirect, by purchase, merger, consolidation, the transfer of property, stock or goodwill or otherwise. This Agreement shall automatically inure to the benefit of, and be enforceable by the Company, including its successors, and assigns, without the need for any further action or approval by you. You specifically agree that this Agreement may be assigned by the Company and enforced by any assignee or successor of the Company.
