2000 STOCK PLAN

STOCK OPTION AGREEMENT

1. Grant of Option. Synacor, Inc., a Delaware corporation (the “Company”), hereby grants to                      (“Optionee”) an option (the “Option”) to purchase a total number of shares of Common Stock (the “Shares”) set forth in the Notice of Stock Option Grant, at the exercise price per share set forth in the Notice of Stock Option Grant (the “Exercise Price”) subject to the terms, definitions and provisions of the Synacor, Inc. (f/k/a CKMP, Inc.) 2000 Stock Option Plan (the “Plan”) adopted by the Company, which is incorporated herein by reference. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option.

If designated an Incentive Stock Option, this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code.

2. Exercise of Option. This Option shall be exercisable during its Term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and with the provisions of Section 9 of the Plan as follows:

(a) Right to Exercise.

(i) This Option may be exercised in whole or in part at any time six months after the Date of Grant, as to Shares which have not yet vested under the vesting schedule indicated on the Notice of Stock Option Grant; provided, however, that Optionee shall execute as a condition to such exercise of this Option, the Early Exercise Notice and Restricted Stock Purchase Agreement attached hereto as Exhibit A (the “Early Exercise Agreement”). If Optionee chooses to exercise this Option solely as to Shares which have vested under the vesting schedule indicated on the Notice of Stock Option Grant, Optionee shall complete and execute the form of Exercise Notice and Restricted Stock Purchase Agreement attached hereto as Exhibit B (the “Exercise Agreement”). Notwithstanding the foregoing, the Company may in its discretion prescribe or accept a different form of notice of exercise and/or stock purchase agreement if such forms are otherwise consistent with this Agreement, the Plan and then-applicable law.

(ii) This Option may not be exercised for a fraction of a share.

(iii) In the event of Optionee’s death, disability or other termination of employment or consulting relationship, the exercisability of the Option is governed by Sections 5, 6 and 7 below, subject to the limitation contained in Section 2(a)(iv) below.

(iv) In no event may this Option be exercised after the Expiration Date of this Option as set forth in the Notice of Stock Option Grant.

(b) Method of Exercise. This Option shall be exercisable by execution and delivery of (i) the Early Exercise Agreement or the Exercise Agreement, whichever is applicable, or of any other written notice approved for such purpose by the Company which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such shares of Common Stock as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be delivered in person or by certified mail to the Secretary of the Company. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price.

No Shares will be issued pursuant to the exercise of an Option unless such issuance and such exercise shall comply with all relevant provisions of applicable law, including the requirements of any stock exchange upon which the Shares may then be listed. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect to such Shares.

3. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination thereof, at the election of Optionee:

(a) cash or check;

(b) cancellation of outstanding indebtedness;

(c) surrender of other shares of Common Stock of the Company which (i) in the case of Shares acquired pursuant to the exercise of a Company option, have been owned by Optionee for more than 6 months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the Exercise Price of the Shares as to which the Option is being exercised;

(d) if there is a public market for the Shares and they are registered under the Exchange Act, delivery of a properly executed exercise notice together with irrevocable instructions to a broker to deliver promptly to the Company the amount of sale or loan proceeds required to pay the Exercise Price; or

(e) subject to Section 505 (e) and (f) of the New York Business Corporation Law, a promissory note in the form attached to this Agreement as Exhibit C, or in any other form approved by the Company.

4. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable federal or state securities or other law or regulation, including any rule under Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by any applicable law or regulation.

5. Termination of Relationship. In the event of termination of Optionee’s Continuous Status as an Employee or Consultant, Optionee may, to the extent otherwise so entitled at the date of such termination (the “Termination Date”), exercise this Option during the Termination Period set forth in the Notice of Stock Option Grant. To the extent that Optionee was not entitled to exercise this Option at such Termination Date, or if Optionee does not exercise this Option within the Termination Period, the Option shall terminate.

6. Disability of Optionee.

(a) Notwithstanding the provisions of Section 5 above, in the event of termination of Optionee’s Continuous Status as an Employee or Consultant as a result of his or her total and permanent disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve months from the Termination Date (but in no event later than the Expiration Date set forth in the Notice of Stock Option Grant and in Section 9 below), exercise this Option to the extent he or she was entitled to exercise it at such Termination Date. To the extent that Optionee was not entitled to exercise the Option on the Termination Date, or if Optionee does not exercise such Option to the extent so entitled within the time specified in this Section 6(a), the Option shall terminate.

(b) Notwithstanding the provisions of Section 5 above, in the event of termination of Optionee’s consulting relationship or Continuous Status as an Employee as a result of a disability not constituting a total and permanent disability (as set forth in Section 22(e)(3) of the Code), Optionee may, but only within six months from the Termination Date (but in no event later than the Expiration Date set forth in the Notice of Stock Option Grant and in Section 9 below), exercise the Option to the extent Optionee was entitled to exercise it as of such Termination Date; provided, however, that if this is an Incentive Stock Option and Optionee fails to exercise this Incentive Stock Option within three months from the Termination Date, this Option will cease to qualify as an Incentive Stock Option (as defined in Section 422 of the Code) and Optionee will be treated for federal income tax purposes as having received ordinary income at the time of such exercise in an amount generally measured by the difference between the Exercise Price for the Shares and the Fair Market Value of the Shares on the date of exercise. To the extent that Optionee was not entitled to exercise the Option at the Termination Date, or if Optionee does not exercise such Option to the extent so entitled within the time specified in this Section 6(b), the Option shall terminate.

7. Death of Optionee. In the event of the death of Optionee (a) during the Term of this Option and while an Employee or Consultant of the Company and having been in Continuous Status as an Employee or Consultant since the date of grant of the Option, or (b) within 30 days after Optionee’s Termination Date, the Option may be exercised at any time within six months following the date of death (but in no event later than the Expiration Date set forth in the Notice of Stock Option Grant and in Section 9 below), by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the Termination Date.

8. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of Optionee.

9. Term of Option. This Option may be exercised only within the Term set forth in the Notice of Stock Option Grant, subject to the limitations set forth in Section 7 of the Plan.

10. Tax Consequences. Set forth below is a brief summary as of the date of this Option of certain of the federal and California or New York tax consequences of exercise of this Option and disposition of the Shares under the laws in effect as of the Date of Grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

(a) Exercise of Incentive Stock Option. If this Option qualifies as an Incentive Stock Option, there will be no regular federal or California or New York income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as an adjustment to the alternative minimum tax for federal tax purposes and may subject Optionee to the alternative minimum tax in the year of exercise.

(b) Exercise of Nonstatutory Stock Option. If this Option does not qualify as an Incentive Stock Option, there may be a regular federal income tax liability and a California or New York income tax liability upon the exercise of the Option. Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Optionee is an employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise.

(c) Disposition of Shares. In the case of a Nonstatutory Stock Option, if Shares are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal and California or New York income tax purposes. In the case of an Incentive Stock Option, if Shares transferred pursuant to the Option are held for at least one year after exercise and are disposed of at least two years after the Date of Grant, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal and California or New York income tax purposes. In either case, the long-term capital gain will be taxed for federal income tax and alternative minimum tax purposes at a maximum rate of 28% if the Shares are held more than one year but less than 18 months after exercise and at 20% if the Shares are held more than 18 months after exercise. If Shares purchased under an Incentive Stock Option are disposed of within one year after exercise or within two years after the Date of Grant, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of (i) the Fair Market Value of the Shares on the date of exercise, or (ii) the sale price of the Shares.

(d) Notice of Disqualifying Disposition of Incentive Stock Option Shares. If the Option granted to Optionee herein is an Incentive Stock Option, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the Incentive Stock Option on or before the later of (i) the date two years after the Date of Grant, or (ii) the date one year after the date of exercise, Optionee shall immediately notify the Company in writing of such disposition. Optionee acknowledges and agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized by Optionee from the early disposition by payment in cash or out of the current earnings paid to Optionee.

11. Withholding Tax Obligations. Optionee understands that, upon exercising a Nonstatutory Stock Option, he or she will recognize income for tax purposes in an amount equal to the excess of the then Fair Market Value of the Shares over the Exercise Price. However, the timing of this income recognition may be deferred for up to six months if Optionee is subject to Section 16 of the Exchange Act. If Optionee is an employee, the Company will be required to withhold from Optionee’s compensation, or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income. Additionally, Optionee may at some point be required to satisfy tax withholding obligations with respect to the disqualifying disposition of an Incentive Stock Option. Optionee shall satisfy his or her tax withholding obligation arising upon the exercise of this Option by one or some combination of the following methods: (a) by cash payment, (b) out of Optionee’s current compensation, (c) if permitted by the Administrator, in its discretion, by surrendering to the Company Shares which (i) in the case of Shares previously acquired from the Company, have been owned by Optionee for more than six months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to or greater than Optionee’s marginal tax rate times the ordinary income recognized, or (d) by electing to have the Company withhold from the Shares to be issued upon exercise of the Option that number of Shares having a Fair Market Value equal to the amount required to be withheld. For this purpose, the Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the “Tax Date”).

If Optionee is subject to Section 16 of the Exchange Act (an “Insider”), any surrender of previously owned Shares to satisfy tax withholding obligations arising upon exercise of this Option must comply with the applicable provisions of Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”).

All elections by Optionee to have Shares withheld to satisfy tax withholding obligations shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions:

(a) the election must be made on or prior to the applicable Tax Date;

(b) once made, the election shall be irrevocable as to the particular Shares of the Option as to which the election is made; and

(c) all elections shall be subject to the consent or disapproval of the Administrator.

12. Market Standoff Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing such underwritten offering of the Company’s securities, Optionee agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the Company’s initial public offering.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one document.

OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE OPTION HEREOF IS EARNED ONLY BY CONTINUING CONSULTANCY OR EMPLOYMENT AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT NOTHING IN THIS AGREEMENT, NOR IN THE COMPANY’S STOCK OPTION PLAN WHICH IS INCORPORATED HEREIN BY REFERENCE, SHALL CONFER UPON OPTIONEE ANY RIGHT WITH RESPECT TO CONTINUATION OF EMPLOYMENT OR CONSULTANCY BY THE COMPANY, NOR SHALL IT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT CAUSE.

Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option.
