This Restricted Stock Agreement (this Agreement) is executed and delivered as of the Grant Date by and between Knight Capital Group, Inc. (the
Company) and the Grantee. The Grantee and the Company hereby agree as follows:



|1. |  | The Company, pursuant to the 2006 Equity Incentive Plan (the Plan), which is incorporated herein by reference, and subject to the terms and conditions thereof, hereby
grants to the Grantee the above mentioned Shares of Restricted Stock in exchange for a payment of $0.01 (the Per Share Price) which represents payment of the par value of the Shares of Restricted Stock.
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. |  | From the Grant Date until the date on which the restrictions applicable to the Shares shall lapse (each such period, a Restricted Period) as set forth above, the Grantee
may not sell, assign, transfer, donate, pledge or otherwise dispose of Shares subject to a Restricted Period. Each certificate representing Restricted Stock shall bear the following legend:
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE COMPANY.



The Grantee shall be entitled to have such legend removed from such certificate when all restrictions with respect to the Shares of
Restricted Stock covered thereby have lapsed. All restrictions imposed on Restricted Stock shall lapse upon the expiration of the Restricted Period applicable to such Shares (as indicated above).



|3. |  | If the Grantees employment with, or provision of services to, the Company shall terminate for any reason other than such Grantees death or disability while Shares are
subject to a Restricted Period, all Shares held by the Grantee still subject to a Restricted Period shall be forfeited upon such termination and the Per Share Price paid with respect to such Shares shall be refunded to the Grantee. In the event of
the Grantees death or disability, the restrictions and forfeiture conditions applicable to the Restricted Stock shall lapse, and the Restricted Stock shall be deemed fully vested in accordance with the terms of the Plan.
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. |  | In the event of a Change-In-Control (as defined in the Plan), the restrictions and forfeiture conditions applicable to the Restricted Stock shall lapse, and the Restricted Stock
shall be deemed fully vested in accordance with the terms of the Plan.
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. |  | During the Restricted Period, the Grantee shall have the right to vote Shares of Restricted Stock and to receive any dividends or distributions paid on such Shares, which dividends
or distributions shall be subject to such restrictions as are deemed appropriate by the Committee.
|-- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|6. |  | The Shares shall be appropriately adjusted to reflect any stock dividend, stock split, combination or exchange of shares or other change in capitalization with a similar substantive
effect upon the Plan or the Restricted Stock. The Committee shall have the power and sole discretion to determine the nature and amount of the adjustment to be made, if any. Any adjustment so made shall be final and binding.
|-- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. |  | The Company shall withhold all applicable taxes required by law from all amounts paid in respect of the Shares upon the vesting of, or lapse of restrictions on, any or all of the
Shares. The Grantee may satisfy the withholding obligation by paying the amount of any taxes in cash or, with the approval of the Committee, shares of stock may be deducted from the payment to satisfy the obligation in full or in part. The amount of
the withholding and the number of shares to be deducted shall be determined by the Committee with reference to the Fair Market Value of the stock when the withholding is required to be made.
|-- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. |  | Except with the consent of the Committee, no Shares shall be assignable or transferable except by will or by the laws of descent and distribution while such shares remain subject to
a Restricted Period.
|-- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. |  | Nothing herein shall obligate the Company or any Subsidiary or Affiliate of the Company to continue the Grantees employment for any particular period or on any particular
basis of compensation.
|-- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10. |  | The obligation of the Company to deliver Shares under this Agreement is specifically subject to all provisions of the Plan and all applicable laws, rules, regulations and
governmental and stockholder approvals.
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|11. |  | Any notice by the Grantee 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 the Grantee shall be in writing and shall be deemed duly given if mailed to the Grantee at the address last specified to the Company by the Grantee.
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12. |  | The grant of Shares herein is not enforceable until this Agreement has been signed by the Grantee and the Company. By executing this Agreement, the Grantee shall be deemed to have
accepted and consented to any action taken under the Plan by the Committee, the Board or its delegates.
