RESTRICTED STOCK UNITS

These Standard Terms and Conditions apply to the Award of restricted stock units granted to an employee or a non-employee director of the Company pursuant to the Ancestry. com Inc. 2009 Stock Incentive Plan (the "Plan"), which are evidenced by a Grant Notice or an action of the Administrator that specifically refers to these Standard Terms and Conditions. In addition to these Terms and Conditions, the restricted stock units shall be subject to the terms of the Plan, which are incorporated into these Standard Terms and Conditions by this reference. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

1. TERMS OF RESTRICTED STOCK UNITS

Ancestry. com Inc., a Delaware corporation (the "Company"), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the "Grant Notice") an award of a number of restricted stock units (the "Award" or the "Restricted Stock Units") specified in the Grant Notice. Each Restricted Stock Unit represents the right to receive one share of the Company's common stock, $0.001 par value per share (the "Common Stock"), upon the terms and subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions, and the Plan, each as amended from time to time. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

2. VESTING OF RESTRICTED STOCK UNITS

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions. After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Award shall become vested as described in the Grant Notice with respect to that number of Restricted Stock Units as set forth in the Grant Notice. Notwithstanding anything contained in these Standard Terms and Conditions to the contrary: (i) if the Participant's Termination of Employment is by reason of death or Disability before all of the Restricted Stock Units have vested, a pro rata portion of the Restricted Stock Units shall become vested, and, unless otherwise determined by the Administrator, the remaining Restricted Stock Units shall be forfeited and canceled as of the date of such Termination of Employment, and (ii) except as provided in Section 5 below, if the Participant's Termination of Employment is for any reason other than death or Disability, any then unvested Restricted Stock Units held by the Participant shall be forfeited and canceled as of the date of such Termination of Employment. For purposes of this Section 2, "pro-rata portion" means a percentage, where the numerator is the portion of the vesting period of the Restricted Stock Units that expired prior to the Participant's Termination of Employment, and the denominator is the number of days in such period.

3. SETTLEMENT OF RESTRICTED STOCK UNITS

Vested Restricted Stock Units shall be settled by the delivery to the Participant or a designated brokerage firm of one share of Common Stock per vested Restricted Stock Unit as soon as reasonably practicable following the vesting of such Restricted Stock Units, and in all events no later than March 15 of the year following the year of vesting (unless delivery is deferred pursuant to a non qualified deferred compensation plan in accordance with the requirements of Section 409A of the Code).

4. RIGHTS AS STOCKHOLDER

The Participant shall have no voting rights or the right to receive any dividends with respect to shares of Common Stock underlying Restricted Stock Units unless and until such shares of Common Stock are reflected as issued and outstanding shares on the Company's stock ledger.

5. CHANGE IN CONTROL

Unless otherwise provided in an employment, severance or other agreement between the Company and the Participant, the following provisions shall apply in the event a Change in Control occurs while the Restricted Stock Units are outstanding:

A. If the Restricted Stock Units are not continued, assumed, converted or substituted for immediately following the Change in Control, the Restricted Stock Units shall become fully vested immediately prior to the Change in Control.

B. If the Restricted Stock Units are continued, assumed, converted or substituted for, the Restricted Stock Units shall be treated as determined by the Administrator.

6. RESTRICTIONS ON RESALES OF SHARES

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common Stock issued in respect of vested Restricted Stock Units, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

7. INCOME TAXES

The Company shall not deliver shares in respect of any Restricted Stock Units unless and until the Participant has made arrangements satisfactory to the Administrator to satisfy applicable withholding tax obligations. Unless the Participant pays the withholding tax obligations to the Company by cash or check in connection with the delivery of the Common Stock, withholding may be effected, at the Company's option, by withholding Common Stock issuable in connection with the vesting of the Restricted Stock Units (provided that shares of Common Stock may be withheld only to the extent that such withholding will not result in adverse accounting treatment for the Company). The Participant acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the delivery of the Restricted Stock Units from any amounts payable by it to the Participant (including, without limitation, future cash wages).

8. NON-TRANSFERABILITY OF AWARD

The Participant represents and warrants that the Restricted Stock Units are being acquired by the Participant solely for the Participant's own account for investment and not with a view to or for sale in connection with any distribution thereof. The Participant further understands, acknowledges and agrees that, except as otherwise provided in the Plan or as permitted by the Administrator, the Restricted Stock Units may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of except other than by will or the laws of descent and distribution and to the extent expressly permitted hereby and at all times in compliance with the U. S. Securities Act of 1933, as amended, and the rules and regulations of the Securities Exchange Commission thereunder, and in compliance with applicable state securities or "blue sky" laws and non-U. S. securities laws.

9. OTHER AGREEMENTS SUPERSEDED

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Restricted Stock Units. Any prior agreements, commitments or negotiations concerning the Restricted Stock Units are superseded.

10. LIMITATION OF INTEREST IN SHARES SUBJECT TO RESTRICTED STOCK UNITS

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person upon vesting of the Restricted Stock Units. Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company's employ or service nor limit in any way the Company's right to terminate the Participant's employment at any time for any reason.
