Form of Stock Option Agreement

 EXHIBIT 10.10 
 THE ACTIVE NETWORK, INC.  
 STOCK OPTION AGREEMENT

 A. The Board has adopted the Plan for the purpose of retaining the services of selected Employees, members of the
Board or the board of directors of any Parent or Subsidiary and independent contractors in the service of the Corporation (or any Parent or Subsidiary). 
 B. Optionee is to render valuable services to the Corporation (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection
with the Corporation’s grant of an option to Optionee. 
 C. All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix. 
 NOW, THEREFORE, it is hereby agreed as follows: 

1. Grant of Option. The Corporation hereby grants to Optionee, as of the Grant Date, an option to purchase the number of
Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 
 2. Option Term. This option shall expire on the Expiration Date, unless sooner terminated in accordance with this Agreement. 

3. Limited Transferability. 
 (a) This option shall be neither transferable nor assignable by Optionee other than by will or the laws of inheritance following Optionee’s death and may be exercised, during Optionee’s
lifetime, only by Optionee. However, Optionee may designate one or more persons as the beneficiary or beneficiaries of this option, so that, if Optionee is holding this outstanding option at the time of his or her death, this option shall, in
accordance with such designation, automatically be transferred to such beneficiary or beneficiaries upon Optionee’s death. Such beneficiary or beneficiaries shall take the transferred option subject to all the terms and conditions of this
Agreement, including (without limitation) the limited time period during which this option may, pursuant to Paragraph 5, be exercised following Optionee’s death. 
 (b) If this option is designated a Non-Statutory Option in the Grant Notice, then this option may be assigned in whole or in part during Optionee’s lifetime to one or more members of Optionee’s
family or to a trust established for the benefit of one or more such family members or to Optionee’s former spouse, to the extent such assignment is in connection with Optionee’s estate plan or pursuant to a domestic relations order. The
assigned portion shall be exercisable only by the person or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option
immediately prior to such assignment. 

 4. Dates of Exercise. This option shall become exercisable for the Option
Shares as specified in the Grant Notice. If the option is exercisable in installments, then as the option becomes exercisable for such installments, those installments shall accumulate, and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option under this Agreement. 
 5. Cessation of
Service. The option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable: 

(a) Should Optionee cease to remain in Service for any reason (other than death, Disability or Misconduct), then this option shall be
exercisable for the number of Option Shares which were Vested Shares at the time of Optionee’s cessation of Service and shall remain exercisable until the earlier of (i) the close of business on the three month anniversary of the
date Optionee’s Service ceases or (ii) the Expiration Date. 
 (b) Should Optionee cease to remain in Service by
reason of death or Disability, then this option shall be exercisable for the number of Option Shares which were Vested Shares at the time of Optionee’s cessation of Service and shall remain exercisable until the earlier of (i) the
close of business on the twelve month anniversary of the date Optionee’s Service ceases or (ii) the Expiration Date. 

(c) No additional vesting will occur after the date Optionee’s Service ceases, and this option shall immediately terminate with
respect to the Unvested Shares. Upon the expiration of any post-Service exercise period or (if earlier) upon the Expiration Date, this option shall terminate with respect to the Vested Shares. 

(d) Should Optionee’s Service be terminated for Misconduct or should Optionee otherwise engage in Misconduct while this option is
outstanding, then this option shall terminate immediately with respect to all Option Shares. 
 6. Accelerated
Vesting. 
 (a) Immediately prior to the effective date of the Change in Control, the Unvested Shares subject to this
option shall automatically become Vested Shares, and this option shall become exercisable for all of the Option Shares. However, the Unvested Shares shall not vest on such an accelerated basis if and to the extent: (i) this option will
be assumed by the successor corporation (or parent thereof) or otherwise continued in effect pursuant to the terms of the Change in Control transaction or (ii) this option is to be replaced with a cash incentive program of the successor
corporation which preserves the spread existing on the Unvested Shares at the time of the Change in Control (the excess of the Fair Market Value of those Unvested Shares over the Exercise Price payable for such shares) and provides for subsequent
payout of that spread no later than the time Optionee would otherwise vest in the Option Shares as set forth in the Grant Notice. 

  
 2 

 (b) Immediately following the Change in Control, this option shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in effect pursuant to the terms of the Change in Control transaction. 

(c) If this option is assumed in connection with a Change in Control or otherwise continued in effect, then this option shall be
appropriately adjusted, upon such Change in Control, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Change in Control had the option been exercised immediately prior to such Change
in Control, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. To the extent that the holders of Common Stock receive cash consideration for their Common Stock in
consummation of the Change in Control, the successor corporation (or its parent) may, in connection with the assumption of this option, substitute one or more shares of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Change in Control. 
 (d) This Agreement shall not in any way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 

7. Adjustment in Option Shares. Should any change be made to the Common Stock by reason of any stock split, stock dividend,
recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration, appropriate adjustments shall be made to (a) the total number
and/or class of securities subject to this option and (b) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder. 

8. Stockholder Rights. The holder of this option shall not have any stockholder rights with respect to the Option Shares
until such person shall have exercised the option, paid the Exercise Price and become the record holder of the purchased Option Shares. 
 9. Manner of Exercising Option. 
 (a) In order to exercise this
option with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons permitted to exercise the option) must take the following actions: 

(i) Execute and deliver to the Corporation a Purchase Agreement for the Option Shares for which the option is exercised;

 (ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms:

  
 3 

 (A) cash or check made payable to the Corporation; or 

(B) a promissory note payable to the Corporation, but only to the extent authorized by the Plan Administrator in
accordance with Paragraph 14. 
 Should the Common Stock be registered under Section 12 of the 1934 Act at
the time the option is exercised, then the Exercise Price may also be paid as follows: 
 (C) in shares of
Common Stock (1) held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation’s earnings for financial reporting purposes and (2) valued at Fair Market
Value on the Exercise Date; or 
 (D) to the extent the option is exercised for Vested Shares, through a special
sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable instructions (1) to a Corporation-designated brokerage firm to effect the immediate sale of
the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable income and employment taxes
required to be withheld by the Corporation by reason of such exercise and (2) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale; 

Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the
Exercise Price must accompany the Purchase Agreement delivered to the Corporation in connection with the option exercise. 
 (iii) Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option; 

(iv) Execute and deliver to the Corporation such written representations as may be requested by the Corporation in order
for it to comply with the applicable requirements of applicable securities laws; and 
 (v) Make appropriate
arrangements with the Corporation (or Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all applicable income and employment tax withholding requirements applicable to the option exercise. 

  
 4 

 (b) As soon as practical after the Exercise Date, the Corporation shall issue to or on
behalf of Optionee (or any other person or persons exercising this option) a certificate for the purchased Option Shares, with the appropriate legends affixed thereto. 
 (c) In no event may this option be exercised for any fractional shares. 
 10.
REPURCHASE RIGHTS. ALL OPTION SHARES ACQUIRED UPON THE EXERCISE OF THIS OPTION SHALL BE SUBJECT TO CERTAIN RIGHTS OF THE CORPORATION AND ITS ASSIGNS TO REPURCHASE THOSE SHARES IN ACCORDANCE WITH THE TERMS SPECIFIED IN THE STOCK PURCHASE
AGREEMENT. 
 11. Compliance with Laws and Regulations. 

(a) The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the
Corporation and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any applicable stock exchange or quotation system on which the Common Stock may be traded at the time of such exercise and
issuance. 
 (b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the
Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not
have been obtained. 
 12. Successors and Assigns. Except to the extent otherwise provided in Paragraphs 3 and 6,
the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee’s permitted assigns and the legal representatives, heirs and legatees of Optionee’s
estate, whether or not any such person shall have become a party to this Agreement or has agreed in writing to join herein and be bound by the terms hereof. 
 13. Notices. Any notice required to be given or delivered to the Corporation under the terms of this Agreement shall be in writing and addressed to the Corporation at its principal corporate
offices. Any notice required to be given or delivered to Optionee shall be in writing and addressed to Optionee at the address indicated below Optionee’s signature line on the Grant Notice. All notices shall be deemed effective upon personal
delivery or on the third day following deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified. 
 14. Financing. The Plan Administrator may, in its absolute discretion and without any obligation to do so, permit Optionee to pay the Exercise Price for the purchased Option Shares (to the
extent such Exercise Price is in excess of the par value of those shares) by delivering a full-recourse, interest-bearing promissory note secured by those Option Shares. The 

  
 5 

 
payment schedule and other terms of any such promissory note shall be established by the Plan Administrator in its sole discretion. 

15. Construction. This Agreement and the option evidenced hereby are made and granted pursuant to the Plan, which is
incorporated herein by reference. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of this Agreement shall prevail. All decisions of the Plan
Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in this option. 
 16. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of Delaware without giving effect to that State’s choice
of law or conflict-of-laws rules. 
 17. Stockholder Approval. If the Option Shares covered by this Agreement
exceed, as of the Grant Date, the number of shares of Common Stock which may be issued under the Plan as last approved by the stockholders, then this option shall be void with respect to such excess shares, unless stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of the Plan. The inability of the Corporation to obtain stockholder approval shall relieve the Corporation
of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. 
 18. At Will Employment. Nothing in this Agreement or in the Plan shall confer upon Optionee any right to continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining Optionee) or of Optionee, which rights are hereby expressly reserved by each, to terminate Optionee’s Service at any time for any
reason, with or without cause. 
 19. Additional Terms Applicable to an Incentive Option. In the event this option
is designated an Incentive Option in the Grant Notice, the following terms and conditions shall also apply to the grant: 
 (a)
This option shall cease to qualify for favorable tax treatment as an Incentive Option if (and to the extent) this option is exercised for one or more Option Shares: (i) more than three months after the date Optionee ceases to be an Employee for
any reason other than death or Disability or (ii) more than twelve months after the date Optionee ceases to be an Employee by reason of Disability. 
 (b) This option shall not become exercisable in the calendar year in which granted if (and to the extent) the aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which this
option would otherwise first become exercisable in such calendar year would, when added to the aggregate value (determined as of the respective date or dates of grant) of the Common Stock and any other securities for which one or more other
Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or 

  
 6 

 
any other option plan of the Corporation or any Parent or Subsidiary) first become exercisable during the same calendar year, exceed $100,000 in the aggregate. To the extent the exercisability of
this option is deferred by reason of the foregoing limitation, the deferred portion shall become exercisable in the first calendar year or years thereafter in which the $100,000 limitation of this Paragraph 19(b) would not be contravened, but such
deferral shall in all events end immediately prior to the effective date of a Change in Control in which this option is not to be assumed or otherwise continued in effect, whereupon the option shall become immediately exercisable as a Non-Statutory
Option for the deferred portion of the Option Shares. 
 (c) Should Optionee hold, in addition to this option, one or more
other options to purchase Common Stock which become exercisable for the first time in the same calendar year as this option, then the foregoing limitations on the exercisability of such options as Incentive Options shall be applied to the option
granted second.

AMENDMENT OF STOCK OPTION AGREEMENT 
 THIS AMENDMENT OF STOCK OPTION AGREEMENT (the “Amendment”) is entered into effective as of [DATE] by and between The Active Network, Inc., a Delaware
corporation (the “Corporation”), and [NAME] (the “Optionee”). 
 WHEREAS, the Corporation granted to the Optionee on [DATE OF ORIGINAL GRANT] an option (the “Option”) to purchase [NUMBER] shares of Common Stock of the
Corporation at an exercise price of $[•] per share pursuant to the Corporation’s 2002 Stock Option/Stock Issuance Plan (the “Plan”), a Notice of Grant of Stock Option and a Stock Option
Agreement (the “Option Agreement”); 
 WHEREAS, on [DATE] the Corporation, pursuant
to this Amendment, has offered to amend the Option Agreement and Optionee has accepted the Amendment within the time period set forth below; and 
 WHEREAS, the Corporation and the Optionee wish to amend the Option Agreement to set forth certain provisions, terms and conditions necessary or advisable in order to enable the Option to be exercised by
means of a net-exercise procedure and to permit withholding of shares in satisfaction of the Optionee’s tax obligations; 

NOW, THEREFORE, the Corporation and the Optionee agree that the following provisions, terms and conditions shall be deemed included as
part of the Option Agreement effective from the date hereof: 
 1. Capitalized Terms. Capitalized terms not otherwise
defined in this Amendment will have the meanings assigned to such terms by the Plan or the Option Agreement. 
 2.
Net-Exercise of Option. In addition to the forms of consideration for payment of the exercise price of the Option authorized by Section 9 of the Option Agreement, the Optionee may also exercise a portion of the Vested Shares by means of
the Net-Exercise procedure. For this purpose, “Net-Exercise” shall have the meaning set forth in Section I.A.2(c) of the Plan. 
 3. Tax Withholding in Shares. The Optionee may elect to have the Corporation deduct from the shares of Common Stock otherwise issuable to the Optionee upon the exercise of the Option, a number of
whole shares of Common Stock having a Fair Market Value, as determined by the Corporation, equal to all or any part of the tax withholding obligations of the Corporation. The Fair Market Value of any shares of Common Stock withheld to satisfy any
such tax withholding obligations shall not exceed the amount determined by the applicable minimum statutory withholding rates. 

4. Acknowledgement of Tax Consequence of Amendment. The Optionee acknowledges that the Optionee has been advised and
understands that, by entering into this Amendment, the Option shall cease to qualify as an Incentive Stock Option to the extent, if any, that the Option qualified as an Incentive Stock Option prior to this Amendment. Accordingly, the Option
shall be treated by the Corporation in its entirety as a Nonstatutory Stock Option. 

 5. Expiration of Amendment Offer. If this Amendment is not
executed by the Optionee on or before the twenty-eighth
(28th) day following its initial offer to the
Optionee, the offer to amend shall be terminated and the provisions described here shall not be effective. 
 6. Continuation
of Other Terms. Except as set forth herein, all other terms and conditions of the Option Agreement shall remain in full force and effect. 
 IN WITNESS WHEREOF, the Corporation and the Optionee have each duly executed this Agreement as of the date first set forth above.
