date of stockholder approval of this Plan, have been reserved but not issued pursuant to any awards granted under the Fortinet, Inc. Amended and Restated 2000 Stock Plan (the “2000 Plan”) and are not subject to any awards granted
thereunder, and (ii) any Shares subject to stock options or similar awards granted under the 2000 Plan that expire or otherwise terminate without having been exercised in full and Shares issued pursuant to awards granted under the 2000 Plan
that are forfeited to or repurchased by the Company, with the maximum number of Shares to be added to the Plan pursuant to clauses (i) and (ii) equal to 17,224,412 Shares. There is no maximum number of Shares with respect to which Options
or Stock Purchase Rights may be granted to any one Optionee, in the aggregate, in any calendar year. The Shares may be authorized but unissued, or reacquired Common Stock. 
 If an Option or Stock Purchase Right expires or becomes unexercisable without having been exercised in full, or is surrendered pursuant to an Option Exchange Program, the unpurchased Shares which
were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). However, Shares that have actually been issued under the Plan, upon exercise of either an Option or Stock Purchase Right, shall not
be returned to the Plan and shall not become available for future distribution under the Plan, except that if Shares of Restricted Stock are repurchased by the Company at their original purchase price, such Shares shall become available for future
grant under the Plan. 
  

	 	4.	 Administration of the Plan. 


 (a)        Administrator. The Plan shall be administered by the Board or a Committee appointed by the Board, which Committee shall be constituted to comply with
Applicable Laws. 
 (b)        Powers of the Administrator. Subject to the
provisions of the Plan and, in the case of a Committee, the specific duties delegated by the Board to such Committee, and subject to the approval of any relevant authorities, the Administrator shall have the authority in its discretion: 

(i)        to determine Fair Market Value; 
  

 -3- 








 (ii)        to select the Service Providers to
whom Options and Stock Purchase Rights may from time to time be granted hereunder; 
 (iii)        to determine the number of Shares to be covered by each such award granted hereunder; 
 (iv)        to approve forms of agreement for use under the Plan; 
 (v)        to determine the terms and conditions of any Option or Stock Purchase Right granted hereunder. Such terms and conditions include, but are not limited to, the exercise
price, the time or times when Options or Stock Purchase Rights may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Option or
Stock Purchase Right or the Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine; 
 (vi)        to determine whether and under what circumstances an Option may be settled in cash under subsection 9(e) instead of Common Stock; 

(vii)        to reduce the exercise price of any Option to the then current Fair Market Value
if the Fair Market Value of the Common Stock covered by such Option has declined since the date the Option was granted; 
 (viii)        to initiate an Option Exchange Program; 
 (ix)        to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred
tax treatment under foreign tax laws; 
 (x)        to allow Optionees to satisfy
withholding tax obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or Stock Purchase Right that number of Shares having a Fair Market Value equal to the amount required to be withheld. 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. All elections by Optionees to have Shares withheld for this purpose shall be made in such form and under such
conditions as the Administrator may deem necessary or advisable; and 
 (xi)        to construe and interpret the terms of the Plan and awards granted pursuant to the Plan. 
 (c)        Effect of Administrator’s Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees.

  

	 	5.	 Eligibility. 


 (a)        Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. For purposes of this Section 5(a),
“Service Providers” shall include prospective Service Providers to whom Options or Stock Purchase Rights are granted in connection with written offers of a service relationship with the Company or any Parent or Subsidiary. Any person who
is not an Employee on the effective date of the grant of an Option may be granted only a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective Employee on the condition that such individual become an Employee shall be deemed
granted effective on the date such person begins service with the Company or any Parent or Subsidiary. The exercise price of such Incentive Stock Options shall be determined as of such date in accordance with Section 8. 
  

 -4- 








 (b)        Each Option shall be designated in the
Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time of the Option with respect to such Shares is granted. 

(c)        Neither the Plan nor any Option or Stock Purchase Right shall confer upon any
Optionee any right with respect to continuing the Optionee’s relationship as a Service Provider with the Company, nor shall it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time,
with or without cause. 
  

	 	6.	 Term of Plan. 


 The Plan shall become effective upon its adoption by the Board. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 14 of the Plan. 
  

	 	7.	 Term of Option. 


 The term of each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who,
at the time the Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years
from the date of grant or such shorter term as may be provided in the Option Agreement. 
  

	 	8.	 Option Exercise Price and Consideration. 


 (a)        The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to
the following: 
 (i)        In the case of an Incentive Stock Option 
 (A)        granted to an Employee who, at the time of grant of such Option, owns stock
representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of
grant. 
 (B)        granted to any other Employee, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of grant. 
 (ii)        in the case of a Nonstatutory Stock Option 
 (A)        granted to any other Service Provider, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. 
 (iii)        Notwithstanding the foregoing, Options may be granted with a per Share exercise
price other than as required above pursuant to a merger or other corporate transaction. 
 (b)        The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an
Incentive Stock Option, shall be determined at the time of grant). Such consideration may consist of (1) cash, 

  

 -5- 








 
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares acquired upon exercise of an Option; have been owned by
the Optionee for more than six months on the date of surrender, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised, (5) consideration
received by the Company under a cashless exercise program implemented by the Company in connection with the Plan, (6) to the extent that a Stock Option Agreement so provides, and if the Common Stock is publicly traded, payment may be made all
or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company in payment of all or part of
the Exercise Price and any withholding taxes, (7) to the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by the delivery (on a form prescribed by the Company) of an
irrevocable direction to pledge Shares to a securities broker or lender approved by the Company, as security for a loan, and to deliver all or part of the loan proceeds to the Company in payment of all or part of the Exercise Price and any
withholding taxes, (8) by such other consideration as may be approved by the Administrator from time to time to the extent permitted by Applicable Law or (9) any combination of the foregoing methods of payment. In making its determination
as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. 
  

	 	9.	 Exercise of Option. 


 (a)        Procedure for Exercise: Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the terms hereof at such times and under such
conditions as determined by the Administrator and set forth in the Option Agreement. Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be tolled during any unpaid leave of absence. An Option may not be exercised
for a fraction of a Share. 
 An Option shall be deemed exercised when the Company receives: (i) written or electronic
notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and
method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee
and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder
shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for
which the record date is prior to the date the Shares are issued, except as provided in Section 12 of the Plan. 
 Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

 (b)        Termination of Relationship as a Service Provider. If an
Optionee’s status as a Service Provider terminates, such Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement (of at least thirty (30) days) to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three
(3) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
  

 -6- 








 (c)        Disability of Optionee. If an
Optionee’s status as a Service Provider terminates as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement (of at least six (6) months)
to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for twelve (12) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (d)        Death of Optionee. If an Optionee dies while a Service Provider, the Option may
be exercised within such period of time as is specified in the Option Agreement (of at least six (6) months) to the extent that the Option is vested on the date of death (but in no event later than the expiration of the term of such Option as
set forth in the Option Agreement) by the Optionee’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable
for twelve (12) months following the Optionee’s death. If, at the time of death, the Optionee is not vested as to the entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. If the
Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (e)        Buy-Out Provision. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and
conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 
  

	 	10.	 Non-Transferability of Options and Stock Purchase Rights. 


 Unless determined otherwise by the Administrator and except as provided for in Section 9(e), the Options (and, prior to exercise, the Shares to be issued upon exercise of Options) and Stock
Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (each as
defined in Section 16a-1(b) of the Exchange Act) with respect to such securities, other than (i) by will, (ii) by the laws of descent or distribution, or (iii) subject to approval of the Administrator, as permitted by Rule 701 of
the Securities Act. Unless determined otherwise by the Administrator, the Option and Stock Purchase Right may be exercised, during the lifetime of the Optionee, only by the Optionee. 
  

	 	11.	 Stock Purchase Rights. 


 (a)        Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with, other awards granted under the Plan and/or cash awards
made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and restrictions related to the offer, including
the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. 
 (b)        Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock purchase agreement shall grant the Company a repurchase option
exercisable upon the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement
shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may determine. 
  

 -7- 








 (c)        Other Provisions. The
Restricted Stock purchase agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d)        Rights as a Stockholder. Once the Stock Purchase Right is exercised, the
purchaser shall have rights equivalent to those of a stockholder and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or
other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 12 of the Plan. 
  

	 	12.	 Changes in Capitalization; Dissolution or Liquidation; Change of Control. 


 (a)        Changes in Capitalization. Subject to any required action by the stockholders
of the Company, the number of shares of Common Stock covered by each outstanding Option or Stock Purchase Right, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options or Stock
Purchase Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per share of Common Stock covered by each such outstanding Option or Stock
Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or
any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company. The conversion of any convertible securities of the Company shall not be deemed to have been “effected
without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option or Stock Purchase Right.

 (b)        Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for an Optionee to have the
right to exercise his or her Option or Stock Purchase Right until fifteen (15) days prior to such transaction as to all of the Optioned Stock covered thereby, including Shares as to which the Option or Stock Purchase Right would not otherwise
be exercisable. In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse as to all such Shares, provided the proposed dissolution
or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, an Option or Stock Purchase Right will terminate immediately prior to the consummation of such proposed action. 
 (c)        Change of Control. In the event of (1) a merger or consolidation of the
Company with or into any other corporation or corporations (but excluding any transaction or series of transactions effected solely for the purpose of reincorporating the Company into another jurisdiction and any transaction(s) in which the
stockholders of the Company immediately prior to such transaction(s) control, immediately after consummation of the transaction(s), more than 50% of the voting power of the surviving entity) or (2) a sale of all or substantially all of the
assets of the Company (collectively referred to as a “Change of Control”) each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option or right substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor corporation (or its Parent or Subsidiary company) refuses to assume or substitute for the Option or Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or Stock Purchase Right is not assumed or substituted for in the event of a
Change of Control, the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase Right shall be fully exercisable for a period of fifteen (15) days or such other period of time as the Administrator
shall determine from the date of such notice, and the Option or Stock Purchase Right shall 

  

 -8- 








 
terminate upon the expiration of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if,
following the Change of Control, the option or right confers the right to purchase or receive, for each Share subject to the Option or Stock Purchase Right immediately prior to the Change of Control, the consideration (whether stock, cash, or other
securities or property) received in the Change of Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders
of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change of Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share subject to the Option or Stock Purchase Right, to be solely common stock of the successor corporation or its Parent
equal in fair market value to the per share consideration received by holders of Common Stock in the Change of Control. 
  

	 	13.	 Time of Granting Options and Stock Purchase Rights. 


 The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or
such other date as is determined by the Administrator. Notice of the determination shall be given to each Service Provider to whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant. 
  

	 	14.	 Amendment and Termination of the Plan. 


 (a)        Effective Date; Term of Plan. This Plan shall become effective as determined by the Board of Directors, but no Options granted under this Plan shall be
exercised and no grants of Restricted Stock shall have their restrictions lapse unless and until this Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date this
Plan is adopted by the Board of Directors. This Plan shall continue in effect for a term of ten (10) years unless sooner terminated under this Section 14. 
 (b)        Amendment and Termination. The Board of Directors in its sole discretion may terminate this Plan at any time. The Board of Directors may
amend this Plan at any time in such respects as the Board of Directors may deem advisable; provided, that any change in the aggregate number of Shares that may be issued under this Plan, other than in connection with an adjustment under
Section 12 of this Plan, shall require approval of the holders of a majority of the outstanding Shares entitled to vote. 
 (c)        Effect of Termination. In the event this Plan is terminated, no Shares shall be issued under this Plan, except upon exercise of an Option granted prior to such termination or
issuance of Shares of Restricted Stock previously credited to a Restricted Stock Account. The termination of this Plan, or any amendment thereof, shall not affect any Shares previously issued to an Optionee, any Option previously granted under this
Plan or any Restricted Stock previously credited to a Restricted Stock Account. 
  

	 	15.	 Conditions Upon Issuance of Shares. 


 (a)        Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of such Option or Stock Purchase
Right and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b)        Investment Representations. As a condition to the exercise of an Option or
Stock Purchase Right, the Administrator may require the person exercising such Option or Stock Purchase Right to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 
  

 -9- 








 16.        Inability to Obtain Authority.
The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company
of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 
 17.        Reservation of Shares. The Company, during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan. 
 18.        Stockholder Approval. The
Plan shall be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws.

 19.        Information to Optionees. Until such time as the Company becomes
subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or is no longer relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act, the Company shall provide to each Optionee the information
described in Rule 701 paragraphs (e)(3), (4), and (5) of Rule 701 under the Securities Act not less frequently than every six months with the financial statements being not more than 180 days old and with such information provided
either by physical or electronic delivery to the Optionees or by written notice to the Optionees of the availability of the information on an Internet site that may be password-protected and of any password needed to access the information. The
Company may request that Optionees agree to keep the information to be provided pursuant to this section confidential. If an Optionee does not agree to keep the information to be provided pursuant to this section confidential, then the Company is
not required to provide the information.

 APPENDIX 1 
 Rules of the Fortinet, Inc. 2008 Stock Plan 
 For the Grant of Stock Options to Optionees
in France 
  

	 	1.	 Introduction. 


 The Board of Directors (the “Board”) of Fortinet, Inc. (the “Company”) has established the Fortinet, Inc. 2008 Stock Plan (the “U.S. Plan”) to attract and retain the best available
personnel for positions of substantial responsibility, to promote the success of the Company’s business and to provide additional incentive to Employees, Directors and Consultants, including Employees and corporate officers of its French
affiliate(s) (a “French Entity”), of which the Company holds directly or indirectly at least 10% of the share capital. 
 Section 4(a) of the U.S. Plan specifically authorizes a committee appointed by the Board (the “Committee”), or the Board itself, to administer the U.S. Plan (the “Administrator”). Section 4(b)(ix) of the U.S.
Plan specifically authorizes the Administrator to prescribe, amend and rescind rules and regulations relating to the U.S. Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax
treatment under foreign tax laws. 
 The Administrator has determined that it is advisable to establish a sub-plan for the
purpose of permitting such stock options granted to Employees and corporate officers of a French Entity to qualify for favorable tax and social security treatment in France. The Administrator, therefore, intends to establish a sub-plan to the U.S.
Plan for the purpose of granting options which qualify for favorable tax and social security treatment in France applicable to options granted under Sections L. 225-177 to L. 225-186 of the French Commercial Code, as amended to eligible
Employees and corporate officers in France who are French tax resident and/or subject to the French social security contributions regime. 
 The terms of the U.S. Plan, as set out in Appendix 1 hereto, shall, subject to the following rules, constitute the Rules of the Fortinet, Inc. 2008 Stock Plan for the Grant of Stock Options to Optionees in France (the
“French Plan”). 
 Under the French Plan, the eligible Optionees will be granted only Options as defined in
Section 2 of this French Plan. The provisions of Section 11 of the U.S. Plan permitting the grant of stock purchase rights are not applicable to grants made under this French Plan. The grant of Options is authorized under Section 5 of
the U.S. Plan. 
  

	 	2.	 Definitions. 


 Capitalized terms not otherwise defined herein shall have the same meanings as set forth in the U.S. Plan. The terms set out below will have the following meanings: 
  

	 	(a)	 The term “Option” shall include both: 


 (i) purchase stock options (rights to acquire Shares as defined by the U.S. Plan repurchased by the Company prior to the vesting of the options); or 
 (ii) subscription stock options (rights to subscribe for newly issued Shares). 
 (b) The term “Optionee” is defined as an eligible person granted an Option pursuant to Section 3 of this French Plan.









	 	(c)	 The term “Grant Date” shall be the date on which the Administrator both: 


 (i)        designates the Optionee; and 
 (ii)        specifies the terms and conditions of the Option, including the number of Shares and
the method for determining the exercise price. 
 (d)        The term “Closed
Period” shall mean the specific periods as set forth by Section L. 225-177 of the French Commercial Code, as amended, during which French-qualifying Options cannot be granted. 
 (e)        The term “Disability’ shall mean disability as determined in categories 2
and 3 under Section L. 341-4 of the French Social Security Code and subject to fulfillment of related conditions. 
 (f)        The term “Effective Grant Date” shall be the date on which the Option is effectively granted (i.e., the date on which the condition precedent of the expiration of a Closed
Period applicable to the Option, if any, is satisfied). Such condition precedent shall be satisfied when the Board, Administrator or other authorized body shall determine that the grant of Options is no longer prevented under a Closed Period. If the
Grant Date does not occur within a Closed Period, or if the Closed Periods are not applicable, the “Effective Grant Date” shall be the same day as the Grant Date. 
  

	 	3.	 Entitlement to Participate. 


 (a)        Any Employee who, on the Effective Grant Date of the Option, is employed under the terms and conditions of an employment contract (“contrat de travail”)
with a French Entity shall be eligible to receive Options under the French Plan, provided he or she also satisfies the eligibility requirements set forth in the U.S. Plan. 
 (b)        Options may not be issued to directors of a French Entity, other than the managing directors (Président du Conseil d’Administration,
Directeur Général, Directeur Général Délégué, Membre du Directoire, Gérant de Sociétés par actions), unless the director is employed by the French Entity, as defined by French
law. 
 (c)        Notwithstanding any provision of the U.S. Plan, Options may not be
issued under the French Plan to Optionees owning more than ten percent (10%) of the Company’s share capital or to individuals other than Employees and corporate officers of a French Entity. 
  

	 	4.	 Conditions of the Option/Exercise Price. 


 (a)        Notwithstanding any provision in the U.S. Plan, the exercise price and number of underlying Shares of the Options will not be modified after the
Effective Grant Date except as provided in Section 6 of this French Plan, or as otherwise authorized by French law. To the extent that modifications are not limited to those described in Section 6, such modification may result in the
Option not qualifying for favorable tax and social security treatment under French law. 
 (b)        The exercise price per Share payable pursuant to Options issued hereunder shall be fixed in accordance with Section 8 of the U.S. Plan. However, notwithstanding the above, in the event
the Company’s Common Stock is publicly traded, the method for determining the exercise price per Share payable pursuant to Options issued hereunder shall be fixed by the Administrator on the Effective Grant Date. The exercise price will be the
higher of: 
 (i)        with respect to purchase Options over the Shares: the
higher of either 80% of the average quotation price of such Shares during the 20 days of quotation immediately preceding the Effective Grant Date or 80% of the average purchase price paid for such Shares by the Company; 
  

 -2- 








 (ii) with respect to subscription Options over the Shares: 80% of the average quotation
price of such Shares during the 20 days of quotation immediately preceding the Effective Grant Date; and 
 (iii) 100% of
the Fair Market Value of Shares, as determined on the Effective Grant Date. 
  

	 	5.	 Exercise of an Option. 


  

	 	(a)	 Exercisability. 


 The Options will become exercisable as set forth in the Option Agreement. However, notwithstanding the above, in the event of the death of an Optionee, all of his or her outstanding Options shall become exercisable under the conditions set
forth in Section 7 of this French Plan. 
  

	 	(b)	 Payment of Exercise Price and Withholding. 


 Notwithstanding any provision of the U.S. Plan, upon exercise of an Option, the full exercise price will be paid either in cash, by check or by wire transfer. Under a cashless exercise program,
the Optionee may give irrevocable instructions to a stockbroker to properly deliver the exercise price to the Company. No delivery of prior owned Shares having a fair market value on the date of delivery equal to the aggregate option price of the
Shares may be used as consideration for exercising the Options. 
  

	 	(c)	 Optionee’s Account. 


 The Shares acquired upon exercise of the Options will be recorded in an account in the name of the shareholder with a broker or in such other manner as the Company may otherwise determine in order to ensure compliance
with applicable law. 
  

	 	6.	 Changes in Capitalization; Change of Control. 


 Notwithstanding any provision in the U.S. Plan, adjustments of the Option issued hereunder shall be made to preclude the dilution or enlargement of benefits under the Option only in the event of
the occurrence of one of the events listed under Section L. 225-181 of the French Commercial Code and according to the provisions of Section L. 228-99 of the French Commercial Code, as amended, as well as according to specific decrees.
Nevertheless, the Administrator may determine to make adjustments in the case of transactions for which adjustments are not authorized under French law, in which case the Options may no longer qualify for the favorable tax and social security
regime. In that respect, the Administrator may at its sole discretion decide that the restriction on the sale or transfer of Shares as defined in Section 10 of this French Plan will no longer apply. 
 In the event of a change in capitalization or Change of Control, as set forth in Section 12 of the U.S. Plan, adjustments to the
terms and conditions of the French-qualified Options or underlying Shares may be made only in accordance with the U.S. Plan and pursuant to applicable French legal and tax rules. Nevertheless, should the Administrator, at its discretion, decide to
make adjustments in a manner that is not recognized as an adjustment under French law, then the Options may no longer qualify as French-qualified Options and the favorable tax and social security treatment may be lost. 
  

	 	7.	 Death. 


 In the event of the death of an Optionee, all Options held by the Optionee shall become immediately vested and exercisable and may be exercised in full by his or her heirs or the legal representative of his or her estate, only within the
six-month period following the death. Any Option that remains unexercised shall expire six months following the date of the Optionee’s death. The six-month exercise period will apply without regard to the term of the Option as described in
Section 8 of this French Plan. 
  

 -3- 









	 	8.	 Term of the Options. 


 The term of the Options shall be no longer than nine years and a half (9.5) years from the Effective Grant Date or such shorter term as the Administrator may provide for, unless it is extended pursuant to the
death provisions in Section 7 of this French Plan. 
  

	 	9.	 Non-Transferability of the Options. 


 Except in the case of death, Options cannot be transferred to any third party and are exercisable only by the Optionee during his or her lifetime. 
  

	 	10.	 Restriction on Transfer of Shares. 


 Notwithstanding any provision of the U.S. Plan, the Company reserves the right to restrict the sale or transfer in any manner of any Shares acquired through the exercise of an Option for a period not to exceed three
years from the date the Option is exercised. Such restriction, if any, will be mentioned in the Option Agreement delivered to the Optionee or any other communication document. 
  

	 	11.	 Buy-Out provisions. 


 Notwithstanding any provision of the U.S. Plan, Buy-Out will not apply and may otherwise result in the disqualification of the Options. 
  


	 	12.	 Disqualification of Options. 


 If the Options are otherwise modified or adjusted in a manner in keeping with the terms of the U.S. Plan or as mandated as a matter of law and the modification or adjustment is contrary to the terms and conditions of
this French Plan, the Options may no longer qualify as French-qualified options. If the Options no longer qualify as French-qualified options, the Administrator may, provided it is authorized to do so under the U.S. Plan, lift, shorten or terminate
certain restrictions applicable to the vesting of the Options, the exercisability of the Options, or the sale of the Shares which may have been imposed under this French Plan or in the Option Agreement delivered to the Optionee. 
  

	 	13.	 Interpretation. 


 It is intended that Options granted under the French Plan shall qualify for the favorable tax and social security treatment applicable to options granted under Sections L. 225-177 to L. 225-186 of the French
Commercial Code, as amended, and in accordance with the relevant provisions set forth by French tax law and the French tax administration. The terms of the French Plan shall be interpreted accordingly and in accordance with the relevant provisions
set forth by French tax and social security laws and relevant Guidelines published by French tax and social security administrations and subject to the fulfilment of legal, tax and reporting obligations. 
  

	 	14.	 Employment Rights. 


 The adoption of this French Plan shall not confer upon the Optionees, or any Employees of a French Entity, any employment rights and shall not be construed as a part of any employment contracts that a French Entity
has with its Employees. 
  

 -4- 









	 	15.	 Amendments. 


 Subject to the terms of the U.S. Plan, the Administrator reserves the right to amend or terminate the French Plan at any time. 
  

	 	16.	 Adoption. 


 The French Plan was adopted by the Administrator on January 28, 2008.

 The Administrator of the Company hereby grants to the optionee (the “Optionee”) named in the Notice of Grant incorporated as Part I of this Option Agreement, an option (the “Option”) to purchase
the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference.
Subject to Section 14(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement (which includes country-specific terms set forth in Exhibit A hereto), the terms and conditions of
the Plan shall prevail. 
  

	 	B.	 Exercise of Option. 


 This Option shall be exercised during its term in accordance with the provisions of Section 9 of the Plan as follows: 
  

	 	1.	 Right to Exercise. 


 (i) This Option shall be exercisable cumulatively according to the vesting schedule set forth in the Notice of Grant. For purposes of this Option Agreement, Shares subject to the Option shall vest based on continued
employment of Optionee with the Optionee’s employer (the “Employer”). 
 (ii) This Option may not be
exercised for a fraction of a Share. 
  

	 	2.	 Method of Exercise. 


 This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit B (the “Exercise Notice”) which shall state the election to exercise the Option, the number of
Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with applicable laws. 
  

	 	C.	 Optionee’s Representations. 


 In the event the Shares have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), at the time this Option is exercised, the Optionee shall, if required by the
Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit C, and shall read the applicable rules of the U.S.
Commissioner of Corporations attached to such Investment Representation Statement.

Company under the Securities Act, Optionee shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in
writing by the Company) (the “Market

	 	F.	 Restrictions on Exercise. 


 This Option may not be exercised until such time as the Plan has been approved by the stockholders 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 law. 
  

	 	G.	 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 Optionee. The terms of the Plan and this

 This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
  

	 	I.	 Entire Agreement. 


 The Plan is incorporated herein by reference. The Plan and this Option Agreement (including Exhibits A, B and C hereto) constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the
Company and Optionee. 
  

	 	J.	 No Guarantee of Continued Service. 


 OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THIS OPTION PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE EMPLOYER (NOT THROUGH THE ACT OF BEING
HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE EMPLOYER’S RIGHT TO TERMINATE

OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE IN ACCORDANCE WITH APPLICABLE LAWS. 
  

	 	K.	 Responsibility for Taxes. 


 Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to Optionee’s participation
in the Plan and legally applicable to Optionee (“Tax-Related Items”), Optionee acknowledges that the ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the
Company. Optionee further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option grant, including, but not
limited to, the grant, vesting or exercise of the Option, the issuance of Shares pursuant to the exercise of the Option, and the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (2) do not
commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Optionee’s liability for Tax-Related Items or achieve any particular tax result. Further, if Optionee has become
subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, Optionee acknowledges that the Company may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

 Prior to any relevant taxable or tax withholding event, as applicable, Optionee will pay or make adequate arrangements
satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Optionee authorizes the Company and/or the Employer, or their respective agents, to withhold all applicable Tax-Related Items by means of one or a
combination of the following: (1) withholding from Optionee’s wages or other cash compensation paid to Optionee by the Company; (2) withholding from proceeds of the sale of Shares acquired upon exercise of the Option either through a
voluntary sale or through a mandatory sale arranged by the Company (on Optionee’s behalf pursuant to this authorization); or (3) withholding in Shares to be issued upon exercise of the Option. 
 To avoid negative accounting treatment or for any other reason, as determined by the Company in its sole discretion, the Company may
withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes,
Optionee is deemed to have been issued the full number of Shares subject to the Option, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of Optionee’s
participation in the Plan. 
 Finally, Optionee shall pay to the Company or the Employer any amount of Tax-Related Items that
the Company or the Employer may be required to withhold or account for as a result of Optionee’s participation in the Plan or Optionee’s purchase of Shares that cannot be satisfied by the means previously described. The Company may refuse
to honor the exercise and refuse to deliver the Shares or the proceeds of the sale of Shares, if Optionee fails to comply with Optionee’s obligations in connection with the Tax-Related Items. 
  

	 	L.	 Nature of Grant. 


 In accepting the Option grant, Optionee acknowledges that: (1) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the
Company at any time, unless otherwise provided in the Plan and this Option Agreement; (2) the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in
lieu of options, even if options have been granted repeatedly in the past; (3) all decisions with respect to future option grants, if any, will be at the sole discretion of the Company; (4) Optionee’s participation in the Plan shall
not create a right to further employment with the Employer and shall not interfere with the ability of the Employer to terminate Optionee’s employment relationship at any time; (5) Optionee is voluntarily participating in the Plan;
(6) the Option and Shares subject to the Option are an extraordinary items that do not constitute compensation of any kind for 

  


					
	 Confidential
	 	Page 4/19	 	Grant Number:









 

 
  
 
services of any kind rendered to the Company or the Employer, and which is outside the scope of Optionee’s employment contract, if any; (7) the
Option and the Shares subject to the Option are not intended to replace any pension rights or compensation; (8) the Option and the Shares subject to the Option are not part of normal or expected compensation or salary for any purposes,
including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension, retirement or welfare benefits or similar payments and in no event should be
considered as compensation for, or relating in any way to, past services for the Company or the Employer or any Subsidiary or affiliate of the Company; (9) the Option grant and Optionee’s participation in the Plan will not be interpreted
to form an employment contract or relationship with the Company, the Employer or any Subsidiary or affiliate of the Company; (10) the future value of the underlying Shares is unknown and cannot be predicted with certainty; (11) if the
underlying Shares do not increase in value, the Option will have no value; (12) if Optionee exercises his or her Option and obtain Shares, the value of those Shares acquired upon exercise may increase or decrease in value, even below the
Exercise Price; (13) in consideration of the grant of the Option, no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from termination of Optionee’s employment by the Company or the
Employer (for any reason whatsoever and whether or not in breach of local labor laws) and Optionee irrevocably releases the Company, the Employer and any Subsidiary and affiliate of the Company from any such claim that may arise; if, notwithstanding
the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, Optionee shall be deemed irrevocably to have waived his or her entitlement to pursue such claim; (14) in the event of termination of Optionee’s
employment (whether or not in breach of local labor laws), Optionee’s right to receive an Option and vest in the Option under the Plan, if any, will terminate effective as of the date that Optionee is no longer actively employed and will not be
extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave” or similar period pursuant to local law); furthermore, in the event of termination of employment (whether
or not in breach of local labor laws), Optionee’s right to exercise the Option after termination of employment will be measured by the date of termination of Optionee’s active employment and will not be extended by any notice period
mandated under local law; the Plan administrator shall have the exclusive discretion to determine when Optionee is no longer actively employed for purposes of Optionee’s Option grant; and (15) the Option and the benefits under the Plan, if
any, will not automatically transfer to another company in the case of a merger, take-over or transfer of liability. 
  

	 	M.	 No Advice Regarding Grant. 


 The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Optionee’s participation in the Plan, or Optionee’s acquisition or sale of the
underlying Shares. Optionee is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding participation in the Plan before taking any action related to the Plan. 
  

	 	N.	 Data Privacy. 


 Optionee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of the Optionee’s personal data as described in this document by
and among, as applicable, the Employer, and the Company and its subsidiaries and affiliates for the exclusive purpose of implementing, administering and managing the Optionee’s participation in the Plan. 
 Optionee understands that the Company and the Employer may hold certain personal information about him or her, including, but not
limited to, the Optionee’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all
options or any other entitlement to shares of stock awarded, canceled, exercised, vested, unvested or outstanding in the Optionee’s favor, for the purpose of implementing, administering and managing the Plan (“Data”). Optionee
understands that Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the Optionee’s country or elsewhere, and that 

  


					
	 Confidential
	 	Page 5/19	 	Grant Number:









 

 
  
 
the recipients’ country (e.g., the United States) may have different data privacy laws and protections than the Optionee’s country. Optionee
understand that he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Optionee authorizes the recipients to receive, possess, use, retain and
transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing his or her participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party
with whom the Optionee may elect to deposit any shares of stock acquired upon exercise of this Option. Optionee understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan.
Optionee understands that he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost,
by contacting in writing his or her local human resources representative. Optionee understands, however, that refusing or withdrawing his or her consent may affect his or her ability to participate in the Plan. For more information on the
consequences of the Optionee’s refusal to consent or withdrawal of consent, Optionee understands that he or she may contact the local human resources representative.

 EXHIBIT A 
 FORTINET, INC. 
 2008 STOCK PLAN 

 ADDITIONAL TERMS AND CONDITIONS OF THE 
 STOCK OPTION AGREEMENT 
 This Exhibit A includes additional terms and conditions that govern the
Option granted to Optionee under the Plan if he or she resides in one of the countries listed below. Certain capitalized terms used but not defined in this Exhibit A have the meanings set forth in the Plan and/or the Option Agreement. 
 This Exhibit A also includes information regarding exchange controls and certain other tax or legal issues of which Optionee should be aware with respect
to his or her participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of January 2009. Such laws are often complex and change frequently. As a result, the
Company strongly recommends that Optionee not rely on the information in this Exhibit A as the only source of information relating to the consequences of his or her participation in the Plan because the information may be out of date at the time
that he or she exercises the Option or sell shares of Common Stock. 
 In addition, the information contained herein is general in nature and
may not apply to Optionee’s particular situation, and the Company is not in a position to assure him or her of a particular result. Accordingly, Optionee is advised to seek appropriate professional advice as to how the relevant laws in his or
her country may apply to his or her situation. 
 Finally, if Optionee is a citizen or resident of a country other than the one in which he
or she is currently residing, the information contained herein may not be applicable to him or her. 
 Australia 
 Securities Law Information 
 If Optionee acquires
Shares of stock pursuant to this Option and he or she offers Shares for sale to a person or entity resident in Australia, the offer may be subject to disclosure requirements under Australian law. Optionee should obtain legal advice on his or her
disclosure obligations prior to making any such offer. 
 Austria 
 Exchange Control Information 
 If Optionee holds Shares purchased under the Plan outside Austria
(even if he or she holds them outside of Austria with an Austrian bank), Optionee understands that he or she must submit an annual report to the Austrian National Bank using the form “Standmeldung/Wertpapiere.” An exemption applies
if the value of the securities held outside Austria as of December 31 does not exceed €3,000,000 or the value of the securities as of any quarter does not exceed €30,000,000. If the former threshold is exceeded, annual reporting
obligations are imposed, whereas if the latter threshold is exceeded, quarterly reports must be submitted. The annual reporting date is December 31; the deadline for filing the annual report is March 31 of the following year. 

When the Shares are sold, there may be exchange control obligations if the cash received is held outside Austria as a separate reporting requirement
applies to any non-Austrian cash accounts. If the transaction volume of all of my cash accounts abroad exceeds €3,000,000, the movements and the balance of all accounts must be reported monthly, as of the last day of the month, on or before the
15th day of the following month, using the form “Meldungen SI-Forderungen und/oder SI-Verpflichtungen.” If the transaction value of all cash accounts abroad is less than €3,000,000, no ongoing reporting requirements apply.

the Company, he or she may be entitled to revoke acceptance of the Option Agreement provided that the revocation is made within one week after he or she signs the Option Agreement. 
 (ii)        The revocation must be in written form to be valid. It is sufficient if Optionee
returns the Option Agreement to the Company or the Company’s representative with language that can be understood as his or her refusal to honor the Option Agreement. It is sufficient if the revocation is sent within one week after Optionee
signed the Option Agreement. 
 Belgium 
 Tax

 The Option must be accepted in writing with the time frame set forth and explained in the separate offer letter,
acceptance form and undertaking form for Optionees in Belgium. Optionee should refer to the offer letter for a more detailed description of the tax consequences of choosing to accept the Option. Optionee should also consult a personal tax advisor

laws), Optionee’s right to vest in this Option, if any, will terminate effective as of the date that is the earlier of: (1) the date Optionee receives notice of termination of employment from the Employer, or
(2) the date Optionee is no longer actively employed by the Employer regardless of any notice period or period of pay in lieu of such notice required under local law (including, but not limited to, statutory law, regulatory law

 Method of Payment 
 Notwithstanding Section E of the Option Agreement or any provision of the Plan to the contrary, Optionee will not be permitted to pay the Exercise Price
by tendering Shares already owned by him or her. 
 Data Privacy Notice and Consent 
 This section supplements Section N of the Option Agreement: 
 Optionee hereby authorizes the Company and the
Company’s representatives to discuss and obtain all relevant information from all personnel, professional or non-professional, involved in the administration of the Plan. Optionee further authorizes the Employer, the Company, and its
Subsidiaries and affiliates to disclose and discuss such information with their advisors. Optionee also authorizes the Employer, Company and its Subsidiaries and affiliates to record such information and to keep such information in the
Optionee’s employee file. 
 China 
 Method of Payment 
 Notwithstanding Section E of the Option Agreement, due to stringent exchange controls and securities
restrictions in China, when Optionee exercises the Option, Optionee must use a “cashless sell-all” exercise pursuant to which he or she delivers irrevocable instructions to the broker to sell all Shares Optionee is entitled to at exercise
and remit the proceeds from sale less any Tax-Related Items and brokerage fees to Optionee in cash. The Company reserves the right to provide Optionee with additional methods of paying the Exercise Price depending upon the development of local laws.

 Because this exercise method requires Shares to be sold, exercises will not be permitted until the Company’s Shares become
publicly traded on a regulated U.S. stock exchange. 
 FOR CLARITY, NOTE THAT, FOR OPTIONEES RESIDENT IN CHINA, THE REQUIREMENT IN THIS
SECTION MAY RESULT IN FOREFEITURE AND CANCELLATION OF SUCH OPTIONEE’S VESTED STOCK OPTIONS. BY WAY OF EXAMPLE ONLY AND WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, IF AN OPTIONEE RESIDENT IN CHINA TERMINATES AS A SERVICE PROVIDER AND THE
OPTIONEE CANNOT SELL THE SHARES UNDERLYING HIS OR HER OPTION DURING THE THREE MONTH POST TERMINATION EXERCISE PERIOD FOR ANY REASON, INCLUDING, AMONG OTHERS, THE COMPANY’S SHARES NOT TRADING ON A REGULATED STOCK EXCHANGE, THEN SUCH OPTIONEE
SHALL NOT BE ENTITLED TO EXERCISE EVEN HIS OR HER VESTED OPTIONS AND SUCH OPTIONEE’S VESTED AND UNVESTED OPTIONS SHALL BE FOREFEITED AND CANCELLED AT THE END OF SUCH THREE MONTH PERIOD. NOTE FURTHER THAT THE REQUIREMENTS, LIMITATIONS AND
RESTRICTIONS IN THIS SECTION APPLY TO THIS CURRENT STOCK OPTION GRANT AND TO ALL PREVIOUS AND FUTURE STOCK OPTION GRANTS, AND OPTIONEE ACKNOWLEDGES AND AGREES TO THIS 
 Exchange Control Information for Optionees who are Chinese Nationals 
 Optionee understands and
agrees that, due to exchange control laws in China, Optionee may be required to immediately repatriate the proceeds from the cashless exercise to China. Optionee further understands that such repatriation of the proceeds may need to be effected
through a special exchange control account established by the Employer, the Company or any of its Subsidiaries or affiliates in China and Optionee hereby consents and agrees that the proceeds from the cashless exercise may be transferred to such
special account prior to being delivered to Optionee’s personal account.

 Germany 
 Exchange Control Information 
 Cross-border payments
in excess of €12,500 must be reported monthly. If Optionee uses a German bank to effect a cross-border payment in excess of €12,500 in connection with the exercise of this Option or sale of securities or the payment of dividends related to
certain securities, the bank will make the report. In this case, Optionee will not have to report the transaction. In addition, Optionee must report any receivables or payables or debts in foreign currency exceeding an amount of approximately
€5,000,000 on a monthly basis. Finally, Optionee must report on an annual basis, Shares holding exceeding 10% of the total voting capital of Fortinet. 
 Hong Kong 
 Securities Law Information 
 The grant of the Option and the Shares issued pursuant to such exercise do not constitute a public offer of securities under Hong Kong law and are available only to employees of the Company or its Subsidiaries or
affiliates participating in the Plan. 
 Please note that the Notice of Grant, Option Agreement, this Exhibit A, the Plan and any other
Option grant documents have not been reviewed by any regulatory authority in Hong Kong. Optionee is cautioned to review the documents related to the Option carefully as it may not include the same information as an offer made by a Hong Kong issuer.
If Optionee is in any doubt about the contents of the Notice of Grant, the Option Agreement, this Exhibit A, the Plan and any other Option grant documents, Optionee should obtain independent legal advice. 
 India 
 Method of Payment 
 Notwithstanding Section E of the Option Agreement, due to exchange control laws that are currently in effect in India, Optionee will not be permitted to
engage in a “sell to cover” exercise whereby a portion of Shares to cover the Exercise Price, any withholdings and brokerage fees are sold and the proceeds are settled in Shares. 
 Fringe Benefits Tax 
 In accepting the grant of the
Option and participating in the Plan, Optionee consents and agrees to assume any and all liability for fringe benefit tax that may be payable by the Company and/or the Employer in connection with the Option. Optionee further understands that the
grant of the Option and participation in the Plan is contingent upon Optionee’s agreement to assume liability for fringe benefit tax payable on the Option. The amount subject to fringe benefits tax is the spread at vesting. The rate is
currently 33.99%, but could change prior to the time Optionee exercises the Option. 
 Further, in accepting the grant of the Option and
participating in the Plan, Optionee agrees that the Company and/or the Employer may collect the fringe benefit tax from Optionee by any of the means set forth in Section K “Responsibility for Taxes” of the Option Agreement or any other
reasonable method established by the Company. Optionee also agrees to execute any other consents or elections required to accomplish the foregoing, promptly upon request by the Company. 
 Exchange Control Information 
 Optionee should be aware that if Optionee remits funds outside of
India to purchase Shares, it is Optionee’s responsibility to comply with the exchange controls in India. Proceeds from the sale of Shares must be repatriated to India within 90 days of receipt. Optionee should obtain a foreign inward remittance
certificate from the bank for Optionee’s records to document compliance with this requirement and submit a copy of the foreign inward remittance certificate to the Employer.

 Securities Law Notice 
 Notwithstanding Section E of the Option Agreement, due to stringent restrictions in Indonesia, when Optionee exercises the Option, Optionee must use a
“cashless sell-all” exercise pursuant to which he or she delivers irrevocable instructions to the broker to sell all Shares Optionee is entitled to at exercise and remit the proceeds from sale less any Tax-Related Items and brokerage fees

transactions, there is a statistical reporting requirement when the Indonesian Bank is receiving Rupiah or foreign currency. For transactions of US$10,000 or more, a description of the transaction must be included in the report filed by the bank
executing the transaction, and Optionee must complete the Transfer Report Form provided by the bank. For transactions of less than US$10,000, the bank through which the transaction is conducted is only required to submit a report which consists of
the type of account and the type of foreign exchange. In addition, if Optionee carries Rupiah (in cash) equal or greater than IDR 100 million out of the customs area of Indonesia (which is unlikely in the context of Optionee’s

 Israel

reserves the right to provide Optionee with additional methods of paying the aggregate Exercise Price depending upon the development of local laws. 
 Because this exercise method requires Shares to be sold, exercises will not be permitted until the Company’s Shares become publicly traded on a regulated U.S. stock exchange. 
 Italy 
 Method of Payment 
 Notwithstanding Section E of the Option Agreement, due to securities restrictions in Italy, when Optionee exercises the Option, Optionee must use a
“cashless sell-all” exercise pursuant to which he or she delivers irrevocable instructions to the broker to sell all Shares Optionee is entitled to at exercise and remit the proceeds from sale less any Tax-Related Items and brokerage fees
to Optionee in cash. Optionee will not be permitted to receive and hold any Shares in connection with the exercise of the Option. The Company reserves the right to provide Optionee with additional methods of paying the aggregate Exercise Price

until the Company’s Shares become publicly traded on a regulated U.S. stock exchange.

extent permitted under Italian law) or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company or its Subsidiaries or affiliates, details of all Options granted, or any other entitlement
to shares of stock awarded, canceled, exercised, vested, unvested or outstanding in Optionee’s favor, for the exclusive purpose of implementing, managing and administering the Plan (“Data”). 
 Optionee also understands that providing the Company with Data is necessary for the performance of the Plan and that Optionee’s refusal to
provide such Data would make it impossible for the Company to perform its contractual obligations and may affect Optionee’s ability to participate in the Plan. The Controller of personal data processing is Fortinet, Inc., with registered
offices at 1090 Kifer Road, Sunnyvale, CA 94086, U.S.A., and, pursuant to Legislative Decree no. 196/2003, its Representative in Italy for privacy purposes is Fortinet Italy, S.r.L, with registered offices at 4 Place de la Defense, 92974 Paris La
Défense Cedex France. Optionee understands that Data will not be publicized, but it may be transferred to banks, other financial institutions, or brokers involved in the management and administration of the Plan. Optionee understands that
Data may also be transferred to the independent registered public accounting firm engaged by the Company. Optionee further understands that the Employer, the Company and/or any of its Subsidiaries or affiliates will transfer Data among themselves as
necessary for the purpose of implementing, administering and managing Optionee’s participation in the Plan, and that the Company and/or any Subsidiary or affiliate may each further transfer Data to third parties assisting the Company in the

use, retain, and transfer Data in electronic or other form, for the purposes of implementing, administering, and managing Optionee’s participation in the Plan. Optionee understands that these recipients may be located in the European Economic
Area or elsewhere, such as the United States. Should the Company exercise its discretion in suspending all necessary legal obligations connected with the management and administration of the Plan, it will delete Data as soon as it has completed all
the necessary legal obligations connected with the management and administration of the Plan. 
 Optionee understands that Data
processing related to the purposes specified above shall take place under automated or non-automated conditions, anonymously when possible, that comply with the purposes for which Data is collected and with confidentiality and security provisions,

 The processing
activity, including communication, the transfer of Data abroad, including outside of the European Economic Area, as herein specified and pursuant to applicable laws and regulations, does not require Optionee’s consent thereto, as the processing
is necessary to performance of contractual obligations related to implementation, administration, and management of the Plan. Optionee understands that, pursuant to Section 7 of the Legislative Decree no. 196/2003, Optionee has the right to,
including but not limited to, access, delete, update, correct, or terminate, for legitimate reason, the Data processing. 
 Furthermore, Optionee is aware that Data will not be used for direct-marketing purposes. In addition, Data provided can be reviewed and questions or complaints can be addressed by contacting Optionee’s local human resources

 Exchange Control Information. 
 Optionee must report in his or her annual tax return: (i) any transfers of cash or Shares to or from Italy exceeding €10,000 or the equivalent amount in U.S. dollars; and (ii) any foreign investments or investments (including
proceeds from the sale of Shares acquired under the Plan) held outside of Italy exceeding €10,000 or the equivalent amount in U.S. dollars, if the investment may give rise to income in Italy. The reporting must be done on Optionee’s
individual income tax return. Optionee is exempt from the formalities in (i) if the investments are made through an authorized broker resident in Italy, as the broker will comply with the reporting obligation on Optionee’s behalf.

 Japan 
 No country-specific provisions.

 Korea 
 Exchange Control Information 

 If Optionee remits funds out of Korea to pay the Exercise Price at exercise of the Option, such remittance must be “confirmed”
by a foreign exchange bank in Korea. This is an automatic procedure, i.e., the bank does not need to “approve” the remittance, and it should take no more than a single day to process. The following supporting documents evidencing
the nature of the remittance must be submitted to the bank together with the confirmation application: (i) the Notice of Grant and Option Agreement; (ii) the Plan; (iii) a document evidencing the type of shares to be acquired and the
amount (e.g., the award certificate); and (iv) Optionee’s certificate of employment. This confirmation is not necessary for cashless exercises because no funds are remitted out of Korea. 
 Additionally, exchange control laws require Korean residents who realize US$500,000 or more from the sale of shares to repatriate the proceeds to Korea
within 18 months of the sale. 
 Malaysia 
 Director Notification Requirements 
 If Optionee is a director of a Malaysian affiliate of the Company, Optionee is subject
to certain notification requirements under the Malaysian Companies Act. Among these requirements is an obligation to notify the Malaysian affiliate in writing when Optionee receives or disposes of an interest (e.g., Options, Shares) in the
Company or any related company (including when Optionee sells Shares acquired pursuant to the exercise of the Option). These notifications must be made within fourteen days of receiving or disposing of any interest in the Company or any related
company. 
 Insider Trading Information 
 Optionee should be aware of the Malaysian insider-trading rules, which may impact Optionee’s acquisition or disposal of Shares acquired from the exercise of the Option. Under the Malaysian insider-trading rules, Optionee is prohibited
from acquiring or selling Shares or rights to Shares (e.g., Options) when Optionee is in possession of information, which is not generally available and which Optionee know or should know will have a material effect on the price of Shares
once such information is generally available. 
 Mexico 
 Labor Law Policy and Acknowledgment 
 In accepting the grant of the Option, Optionee expressly recognizes that Fortinet,
Inc., with registered offices at 1090 Kifer Road, Sunnyvale, CA 94086, U.S.A, is solely responsible for the administration of the Plan and that Optionee’s participation in the Plan and acquisition of Shares do not constitute an employment
relationship between Optionee and Fortinet, Inc. since Optionee is participating in the Plan on a wholly commercial basis and his or her sole Employer is Fortinet, Inc., located at Rodriguez Saro #615, Col. Del Valle, C.P. 03100, Mexico DF. Based on
the foregoing, Optionee expressly recognizes that the Plan and the benefits that he or she may derive from participating in the Plan do not establish any rights between Optionee and the Employer, Fortinet, Inc., and do not form part of the
employment conditions

and/or benefits provided by Fortinet, Inc., and any modification of the Plan or its termination shall not constitute a change or impairment of the terms and
conditions of Optionee’s employment. 
 Optionee further understands that his or her participation in the Plan is as a result of a
unilateral and discretionary decision of Fortinet, Inc.; therefore, Fortinet, Inc. reserves the absolute right to amend and/or discontinue Optionee’s participation at any time without any liability to Optionee. 
 Finally, Optionee hereby declares that he or she does not reserve to himself or herself any action or right to bring any claim against Fortinet, Inc. for
any compensation or damages regarding any provision of the Plan or the benefits derived under the Plan, and Optionee therefore grants a full and broad release to Fortinet, Inc., its affiliates, branches, representation offices, its shareholders,
officers, agents, or legal representatives with respect to any claim that may arise. 
 Política Laboral y Reconocimiento/Aceptación 

 Al aceptar el otorgamiento de la Opción de Compra de Acciones, el Optionee expresamente reconoce que Fortinet, Inc., con domicilio
registrado ubicado en Sunnyvale, CA, U.S.A., es la única responsable por la administración del Plan y que la participación del Optioneee en el Plan y en su caso la adquisición de las Opciones de Compra de Acciones o
Acciones no constituyen ni podrán interpretarse como una relación de trabajo entre el Optioneee y Fortinet, Inc., ya que el Optioneee participa en el Plan en un marco totalmente comercial y su único Patrón lo es Fortinet,
Inc. con domicilio en Rodriguez Saro #615, Col. Del Valle, C.P. 03100, Mexico DF, Mexico. Derivado de lo anterior, el Optioneee expresamente reconoce que el Plan y los beneficios que pudieran derivar de la participación en el Plan no
establecen derecho alguno entre el Optioneee y el Patrón, Fortinet, Inc. y no forma parte de las condiciones de trabajo y/o las prestaciones otorgadas por Fortinet, Inc. y que cualquier modificación al Plan o su terminación no
constituye un cambio o impedimento de los términos y condiciones de la relación de trabajo del Optioneee. 
 Asimismo, el
Optioneee reconoce que su participación en el Plan es resultado de una decisión unilateral y discrecional de Fortinet, Inc.; por lo tanto, Fortinet, Inc. se reserva el absoluto derecho de modificar y/o terminar la participación
del Optioneee en cualquier momento y sin responsabilidad alguna frente el Optioneee. 
 Finalmente, el Optioneee por este medio declara que
no se reserve derecho o acción alguna que ejercitar en contra de Fortinet, Inc. por cualquier compensación o daño en relación con las disposiciones del Plan o de los beneficios derivados del Plan y por lo tanto, el
Optioneee otorga el más amplio finiquito que en derecho proceda a Fortinet, Inc., sus afiliadas, subsidiarias, oficinas de representación, sus accionistas, funcionarios, agentes o representantes legales en relación con cualquier
demanda que pudiera surgir. 
 Netherlands 
 Insider Trading Information 
 Optionee should be aware of Dutch insider trading rules which may impact the sale of Shares
acquired under the Plan. In particular, Optionee may be prohibited from effecting certain transactions if he or she has insider information regarding the Company. 
 By accepting the grant of the Option and participating in the Plan, Optionee acknowledges having read and understood this Securities Law Information and further acknowledges that it is Optionee’s responsibility
to comply with the following Dutch insider trading rules. 
 Under Article 46 of the Act on the Supervision of the Securities Trade 1995,
anyone who has “insider information” related to an issuing company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is defined as knowledge of details concerning the
issuing company to which the securities relate that is not public and which, if published, would reasonably be expected to affect the stock price, regardless of the development of the price. The insider could be any employee of the Company or a
subsidiary or affiliate in the Netherlands who has inside information as described herein. 
 Given the broad scope of the definition of
inside information, certain employees of the Company working at a subsidiary or affiliate in the Netherlands (including an Optionee in the Plan) may have inside information and, thus, would be prohibited from effectuating a transaction in securities
in the Netherlands

note that if Optionee uses a cashless method of exercise, this requirement will not apply because no funds will be transferred out of Poland. If Optionee acquires Shares through participation in the Plan, Optionee must file an annual report with the
National Bank of Poland declaring ownership of foreign shares. This report is filed on a special form available on the website of the National Bank of Poland.

 If Optionee is a director, associate director or shadow director of a Singapore affiliate of the Company, Optionee is subject to certain notification requirements under the Singapore Companies Act. Directors must
notify the Singapore Subsidiary in writing of an interest (e.g., Options, Shares) in the Company or any related companies within two days of (i) its acquisition or disposal, (ii) any change in a previously disclosed interest
(e.g., when the Option is exercised), or (iii) becoming a director. 
 Spain 
 Labor Law Acknowledgment 
 This section supplements
Section L of the Option Agreement: 
 In accepting the Option, Optionee acknowledges that he or she consents to participation in the Plan and
has received a copy of the Plan. 
 The Optionee understands that the Company has unilaterally, gratuitously and discretionally decided to
grant options under the Plan to individuals who may be employees of the Company or its Subsidiaries or affiliates throughout the world. The decision is a limited decision that is entered into upon the express assumption and condition that any grant
will not economically or otherwise bind the Company or any of its Subsidiaries or affiliates on an ongoing basis. Consequently, Optionee understands that the Option is granted on the assumption and condition that the Option or the Shares acquired
upon exercise shall not become a part of any employment contract (either with the Company or any of its Subsidiaries) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right
whatsoever. In addition, Optionee understands that this grant would not be made to the Optionee but for the assumptions and conditions referred to above; thus, the Optionee acknowledges and freely accepts that should any or all of the assumptions be
mistaken or should any of the conditions not be met for any reason, then any grant of options shall be null and void. 
 Exchange Control Information 

 It is Optionee’s responsibility to comply with exchange control regulations in Spain. The purchase of Shares must be declared by the
purchaser for statistical purposes to the Spanish Direccion General de

Política Comercial y de Inversiones Extranjeras (the “DGPCIE”), of the Ministerio de Economia. If Optionee purchases
the Shares through the use of a Spanish financial institution, that institution will automatically make the declaration to the DGPCIE for Optionee. Otherwise, Optionee must make the declaration by filing the appropriate form with the
DGPCIE. In addition, Optionee must also file a declaration of the ownership of the securities with the Directorate of Foreign Transactions each January while the Shares are owned. 
 When receiving foreign currency payments derived from the ownership of Shares (i.e., as a result of the sale of the Shares), Optionee must inform the financial institution receiving the
payment, the basis upon which such payment is made. Optionee will need to provide the institution with the following information: (i) Optionee’s name, address, and fiscal identification number; (ii) the name and corporate domicile of
the Company; (iii) the amount of the payment; (iv) the currency used; (v) the country of origin; (vi) the reasons for the payment; and (vii) any additional information that may be required. 
 If Optionee wishes to import the ownership title of the Shares (i.e., share certificates) into Spain, Optionee must declare the importation of
such securities to the DGPCIE. 
 Sweden 
 No country-specific provisions. 
 Switzerland 
 Securities Law Information 
 Optionee acknowledges that the offer to participate in the Plan is
considered a private offering in Switzerland and is therefore not subject to registration in Switzerland. 
 Taiwan 
 Securities Law Information 
 This offer of Options
and the Shares to be issued pursuant to the Plan is available only for employees of the Company and its Subsidiaries. It is not a public offer of securities by a Taiwanese company; therefore, it is exempt from registration in Taiwan. 
 Exchange Control Information 
 Optionee may acquire
foreign currency, and remit the same out of Taiwan, up to US$5 million per year without justification. When remitting funds for the purchase of Shares pursuant to the Plan, such remittances should be made through an authorized foreign exchange bank.
In addition, if Optionee remits TWD$500,000 or more in a single transaction, Optionee must submit a Foreign Exchange Transaction Form to the remitting bank. If the transaction amount is US$500,000 or more in a single transaction, Optionee must also
provide supporting documentation to the satisfaction of the remitting bank. 
 Thailand 
 Exchange Control Information 
 It is Optionee’s
responsibility to comply with all exchange control regulations in Thailand. If Optionee exercises the Option with cash, Optionee may apply directly to a commercial bank in Thailand for approval to remit up to US$1,000,000 per year for the purchase
of Shares. If Optionee exercises the Option by way of a cashless method of exercise, no application to a commercial bank is required. In addition, Optionee is required to immediately repatriate the proceeds from the sale of the Shares acquired
pursuant to the exercise of the Option to Thailand. Within the next 360 days after the repatriation date, Optionee must deposit the sale proceeds into a foreign currency deposit account or convert them to local currency. If the amount of such sale
proceeds is equal to or greater than US$20,000, Optionee must specifically report the inward remittance to the Bank of Thailand on a Foreign Exchange Transaction Form through the bank at which Optionee deposits or converts the sale proceeds.

 Turkey 
 Exchange Control Information

	 	Page 17/19	 	Grant Number:









 

 
  
 Exchange control regulations
require Turkish residents to buy Shares through intermediary financial institutions that are approved under the Capital Market Law (i.e., banks licensed in Turkey). Therefore, if Optionee uses cash to exercise Options, the funds must be
remitted through a bank or other financial institution licensed in Turkey. A wire transfer of funds by a Turkish bank will satisfy this requirement. This requirement does not apply to cashless exercises, as no funds leave Turkey. 
 United Kingdom 
 Joint Election 
 As a condition of participation in the Plan and the exercise of the Option, Optionee agrees to accept any liability for secondary Class 1 national
insurance contributions which may be payable by the Company and/or the Employer in connection with the Option and any event giving rise to Tax-Related Items (the “Employer NICs”). Without prejudice to the foregoing, Optionee agrees to
execute a joint election with the Company, the form of such joint election being formally approved by Her Majesty’s Revenue & Customs (“HMRC”) (the “Joint Election”), and any other required consent or election.
Optionee further agrees to execute such other joint elections as may be required between him or her and any successor to the Company and/or the Employer. Optionee further agrees that the Company and/or the Employer may collect the Employer NICs from
him or her by any of the means set forth in Section K of the Option Agreement. 
 If Optionee does not enter into a Joint Election prior to
exercise of the Option, he or she will not be entitled to exercise the Option unless and until he or she enters into a Joint Election and no Shares will be issued to Optionee under the Plan, without any liability to the Company and/or the Employer.

 Tax Obligations/Withholding Authorization 
 This section supplements Section K of the Option Agreement. 
 If payment or withholding of the Tax-Related Items (including the
Employer NICs) is not made within ninety (90) days of the event giving rise to the Tax-Related Items or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003 (the “Due Date”),
the amount of any uncollected Tax-Related Items shall constitute a loan owed by Optionee to the Employer, effective as of the Due Date. Optionee agrees that the loan will bear interest at the then-current official rate of HMRC, it shall be
immediately due and repayable, and the Company or the Employer may recover it at any time thereafter by any of the means referred to in Section K of the Option Agreement. Notwithstanding the foregoing, if Optionee is a director or executive officer
of the Company (within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), he or she shall not be eligible for a loan from the Company to cover the Tax-Related Items. In the event that Optionee is a
director or executive officer and Tax-Related Items are not collected from or paid by him or her by the Due Date, the amount of any uncollected Tax-Related Items will constitute a benefit to Optionee on which additional income tax and NICs
(including the Employer NICs) will be payable. Optionee will be responsible for reporting any income tax and NICs (including the Employer NICs) due on this additional benefit directly to HMRC under the self-assessment regime. 
 In addition, the Optionee agrees that the Company and/or the Employer may calculate the Tax-Related Items to be withheld and accounted for by reference
to the maximum applicable rates, without prejudice to any right the Optionee may have to recover any overpayment from the relevant tax authorities. 
 United Arab Emirates 
 Securities Law Information 
 The Plan is only being offered to eligible employees and is in the nature of providing equity incentives to eligible employees of the Company’s Subsidiary in the United Arab Emirates.

 Set forth below is a brief summary
as of January 2009 of some of the U.S. federal tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A
TAX ADVISOR BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. This summary does not include any state income tax or other tax information besides U.S. federal tax information. 
 Exercise of Nonstatutory Stock Option 
 There may be a federal income tax liability
upon the exercise of a Nonstatutory Stock Option. The 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 or a former 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 in cash equal to a
percentage of this compensation income at the time of exercise, and may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise. Optionee will be responsible for the difference
(if any) between his or her actual tax liability and the amount withheld. 
 Disposition of Shares 
 In the case of an NSO, 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 income tax purposes. If Shares are held for less than one year, any gain realized on disposition of the Shares will be treated as a long-term capital gain for federal income tax purposes. The Company will not
withhold or report any capital gain Optionee realizes; it is Optionee’s responsibility to report and pay any taxes due when Optionee sells Shares.

 Regardless of any
provisions to the contrary in this Agreement or in the Plan, no Shares subject to the Option shall vest until the first anniversary date of the Effective Grant Date (the “Anniversary Date”) except in the event of death of Optionee.

 Pursuant to the terms of the Plan, vesting of the Option shall be tolled during any unpaid leave of absence of the

 This Option may be exercised, to the extent it is then vested, for up to three months after Optionee ceases to be an Employee or a

by reason of death or Disability (as defined under the French Plan), the restriction on the sale of Shares described in Section G of the Option Agreement, will not apply to the Shares acquired upon exercise of the Option, provided all required
conditions are satisfied. In no event shall this Option be exercised after the Term/Expiration Date as provided above, except in the event of Optionee’s death. 
  

	II.	 AGREEMENT. 


  

	 	A.	 Grant of Option. 


 The Administrator of the Company hereby grants to the optionee (the “Optionee”) named in the Notice of Grant incorporated as Part I of this Option Agreement, as of the Effective Grant Date, an option (the
“Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan (including
the French Plan), which is incorporated herein by reference. Subject to Section 14(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall
prevail. Optionee understands and agrees that the Option is offered subject to and in accordance with the terms of the Plan (which includes the U.S. Plan and the French Plan). Optionee further agrees to be bound by the terms of the Plan and the
terms of the Option as set forth in this Option Agreement. 
 This Option is intended to be a French-qualified Option that
qualifies for the favorable tax and social security regime in France, as set forth in the French Plan. Certain events may affect the status of the Option as a French-qualified Option and the Option may be disqualified in the future. The Company does
not make any undertaking or representation to maintain the qualified status of the French-qualified Option during the life of the Option, and the Optionee will not be entitled to any damages if the Option no longer qualifies as a French-qualified
Option. 
  

	 	B.	 Exercise of Option. 


 This Option shall be exercised during its term in accordance with the provisions of Section 5 of the French Plan as follows: 
  


					
	 Confidential
	 	Page 2/9	 	Grant Number:









 

 
  

	 	1.	 Right to Exercise. 


  

	 	(i)	 This Option shall be exercisable cumulatively according to the vesting schedule set forth in the Notice of Grant. For purposes of this Option Agreement, Shares
subject to the Option shall vest based on continued employment of Optionee with the Optionee’s employer (the “Employer”). 


  

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


  

	 	2.	 Method of Exercise. 


 This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the
Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as
to all exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with
applicable laws. 
  

	 	C.	 Optionee’s Representations. 


 In the event the Shares have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), at the time this Option is exercised, the Optionee shall, if required by the
Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit C, and shall read the applicable rules of the U.S.
Commissioner of Corporations attached to such Investment Representation Statement. 
  

	 	D.	 Lock-Up Period. 


 Optionee hereby agrees that, if so requested by the Company or any representative of the underwriters (the “Managing Underwriter”) in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in
writing by the Company) (the “Market Standoff Period”) following the effective date of a registration statement of the Company filed under the Securities Act. The Company may impose stop-transfer instructions with respect to securities
subject to the foregoing restrictions until the end of such Market Standoff Period. 
  

	 	E.	 Method of Payment  


  

	 	1.	 Method of Payment.

	 	(b)	 check; or 


  


					
	 Confidential
	 	Page 3/9	 	Grant Number:









 

 
  
 (c) consideration
received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan if such exercise occurs after the Sale Restriction described in Section G is no longer applicable. 
  

	 	F.	 Restrictions on Exercise. 


 This Option may not be exercised until such time as the Plan has been approved by the stockholders 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 law. 
  

	 	G.	 Restriction on Sale of Shares. 


 1.        After issuance of the Shares to the Optionee upon exercise of the Option, the Optionee will not be permitted to sell, transfer, or assign the Shares until the fourth
(4th) anniversary of the Effective Grant Date, or such other date as is required to comply with the applicable compulsory holding period for French-qualified options set forth by Section 163 bis C of the French Tax Code. The restriction on
the sale of Shares described in Section G of the Option Agreement will continue to apply even in case of termination of the Optionee unless the termination is due to death or Disability (as defined under the French Plan) of the Optionee or is due to
dismissal or forced retirement according to the conditions set forth in Section 91 ter of the Annex II of the French tax Code and as construed by the applicable guidelines. In no event will the restriction on the sale of the Shares exceed a
period of three (3) years from the date the Option is exercised. If the holding period applicable to Shares underlying the French-qualified Option is not met, this Option may not receive favorable tax and social security treatment under French
law. In this case, the Optionee accepts and agrees that he or she will be responsible for paying personal income tax and his or her portion of social security contributions resulting from exercise of the Option. 
 2.        At the Company’s discretion, the share certificates for all Shares subject to the
French-qualified Option may bear a legend setting forth the restriction on sale for the time period set out in this Section G. In addition, the share certificates may be held until the expiration of the holding period, at the Company’s
discretion, either (a) by the Company, (b) by a transfer agent designated by the Company, (c) in an account in the name of the Optionee with a broker designated by the Company, or (d) in such manner as the Company may otherwise
determine in compliance with French law. 
 3.        If Optionee qualifies as a
managing director under French law (“mandataires sociaux”, i.e., Président du Conseil d’Administration, Directeur Général, Directeur Général Délégué, Membre du Directoire,
Gérant de sociétés par actions), and is otherwise eligible to receive Options under the Plan, and is subject to shareholding restrictions under French law, Optionee must hold 20% of the Shares received at exercise in a
nominative account. Optionee may not sell these Shares until he or she ceases to serve as a managing director, as long as this restriction is a requirement under French law or unless law or regulations provide for a lower percentage (in which case
this requirement will apply to the lower percentage of Shares held). 
  

	 	H.	 Non-Transferability of Option. 


 This Option may not be transferred or assigned 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 Optionee. The terms of the
Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
  

	 	I.	 Term of Option. 


 Except in the event of Optionee’s death, this Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of
this Option.

	 	J.	 Entire Agreement. 


 The Plan is incorporated herein by reference. The Plan (including the French Plan) and this Option Agreement (including Exhibits A, B and C hereto) constitute the entire agreement of the parties with respect to the
subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a
writing signed by the Company and Optionee. 
  

	 	K.	 No Guarantee of Continued Service. 


 OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THIS OPTION PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS AN EMPLOYEE OR A CORPORATE OFFICER AT THE WILL OF THE EMPLOYER (NOT THROUGH THE
ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN
EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS AN EMPLOYEE OR CORPORATE OFFICER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE EMPLOYER’S RIGHT TO TERMINATE
OPTIONEE’S RELATIONSHIP AS AN EMPLOYEE OR A CORPORATE OFFICER AT ANY TIME, WITH OR WITHOUT CAUSE IN ACCORDANCE WITH APPLICABLE LAWS. 
  

	 	L.	 Responsibility for Taxes. 


 Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to Optionee’s participation
in the Plan and legally applicable to Optionee (“Tax-Related Items”), Optionee acknowledges that the ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the
Company. Optionee further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option grant, including, but not
limited to, the grant, vesting or exercise of the Option, the issuance of Shares pursuant to the exercise of the Option, and the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (2) do not
commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Optionee’s liability for Tax-Related Items or achieve any particular tax result. Further, if Optionee has become
subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, Optionee acknowledges that the Company may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

 Prior to any relevant taxable or tax withholding event, as applicable, Optionee will pay or make adequate arrangements
satisfactory to the Company and/or the Employer within the limits set forth by French law to satisfy all Tax-Related Items. In this regard, Optionee authorizes the Company and/or the Employer, or their respective agents, to withhold all applicable
Tax-Related Items by means of one or a combination of the following: (1) withholding from Optionee’s wages or other cash compensation paid to Optionee by the Company; (2) withholding from proceeds of the sale of Shares acquired upon
exercise of the Option either through a voluntary sale or through a mandatory sale arranged by the Company (on Optionee’s behalf pursuant to this authorization); or (3) withholding in Shares to be issued upon exercise of the Option.
Optionee acknowledges and agrees that if Tax-Related Items are satisfied by withholding from the proceeds of the sale of the Shares and the amount withheld is in excess of the amount due, the Company and/or the Employer will refund the excess amount
to Optionee as soon as administratively practicable and without interest. 
 To avoid negative accounting treatment or for
any other reason, as determined by the Company in its sole discretion, the Company may withhold or account for Tax-Related Items by 

  


					
	 Confidential
	 	Page 5/9	 	Grant Number:









 

 
  
 
considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by
withholding in Shares, for tax purposes, Optionee is deemed to have been issued the full number of Shares subject to the Option, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items due as a
result of any aspect of Optionee’s participation in the Plan. 
 Finally, Optionee shall pay to the Company or the
Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of Optionee’s participation in the Plan or Optionee’s purchase of Shares that cannot be satisfied by the means
previously described. The Company may refuse to honor the exercise and refuse to deliver the Shares or the proceeds of the sale of Shares, if Optionee fails to comply with Optionee’s obligations in connection with the Tax-Related Items.

  

	 	M.	 Nature of Grant. 


 In accepting the Option grant, Optionee acknowledges that: (1) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the
Company at any time, unless otherwise provided in the Plan and this Option Agreement; (2) the grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in
lieu of options, even if options have been granted repeatedly in the past; (3) all decisions with respect to future option grants, if any, will be at the sole discretion of the Company; (4) Optionee’s participation in the Plan shall
not create a right to further employment with the Employer and shall not interfere with the ability of the Employer to terminate Optionee’s employment relationship at any time; (5) Optionee is voluntarily participating in the Plan;
(6) the Option and Shares subject to the Option are an extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Company or the Employer, and which is outside the scope of Optionee’s
employment contract, if any; (7) the Option and the Shares subject to the Option are not intended to replace any pension rights or compensation; (8) the Option and the Shares subject to the Option are not part of normal or expected
compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension, retirement or welfare benefits or
similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or the Employer or any Subsidiary or affiliate of the Company; (9) the Option grant and Optionee’s
participation in the Plan will not be interpreted to form an employment contract or relationship with the Company, the Employer or any Subsidiary or affiliate of the Company; (10) the future value of the underlying Shares is unknown and cannot
be predicted with certainty; (11) if the underlying Shares do not increase in value, the Option will have no value; (12) if Optionee exercises his or her Option and obtain Shares, the value of those Shares acquired upon exercise may
increase or decrease in value, even below the Exercise Price; (13) in consideration of the grant of the Option, no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from termination of
Optionee’s employment by the Company or the Employer (for any reason whatsoever and whether or not in breach of local labor laws) and Optionee irrevocably releases the Company, the Employer and any Subsidiary and affiliate of the Company from
any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, Optionee shall be deemed irrevocably to have waived his or her entitlement to pursue such claim;
(14) in the event of termination of Optionee’s employment, Optionee’s right to receive an Option and vest in the Option under the Plan, if any, will terminate effective as of the date that Optionee is no longer actively employed and
will not be extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave” or similar period pursuant to local law); furthermore, in the event of termination of
employment (whether or not in breach of local labor laws), Optionee’s right to exercise the Option after termination of employment will be measured by the date of termination of Optionee’s active employment and will not be extended by any
notice period mandated under local law; the Plan administrator shall have the exclusive discretion to determine when Optionee is no longer actively employed for purposes of Optionee’s Option grant; and (15) the Option and the benefits
under the Plan, if any, will not automatically transfer to another company in the case of a merger, take-over or transfer of liability.

	 	M.	 No Advice Regarding Grant. 


 The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Optionee’s participation in the Plan, or Optionee’s acquisition or sale of the
underlying Shares. Optionee is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding participation in the Plan before taking any action related to the Plan. 
  

	 	N.	 Data Privacy. 


 Optionee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of the Optionee’s personal data as described in this document by and among, as

 FORTINET, INC. 
 2008 STOCK PLAN 
 COUNTRY SUPPLEMENT & UNDERTAKING 
 FOR OPTIONEES IN BELGIUM 
 This
supplement has been prepared to provide the Optionee with a summary of certain key information regarding the Optionee’s participation in the Fortinet, Inc 2008 Stock Plan (the “Plan”). 
 This supplement is based on the tax and other laws concerning stock options in effect in Belgium as of March 2009. Such laws are often complex and change
frequently. As a result, the information contained in this supplement may be outdated at the time the Option is exercised or when the Optionee sells shares acquired under the Plan. 
 In addition, this supplement is general in nature. It is not intended to serve as specific tax or investment advice and does not discuss all of the various laws, rules and regulations that may
apply. It may not apply to the Optionee’s particular tax or financial situation, and Fortinet, Inc. (“Fortinet”) is in no position to assure any particular tax result. Accordingly, the Optionee is strongly advised to seek
appropriate professional advice as to how the tax or other laws in the Optionee’s country apply to his or her specific situation. 
 If the Optionee is a citizen or resident of another country or is considered a resident of another country for local law purposes, the information contained in this summary may not be applicable to the Optionee. The Optionee is advised to
seek appropriate professional advice as to how the tax or other laws in the Optionee’s country apply to his or her specific situation. 
 Capitalized terms used but not defined herein shall have the same meanings ascribed to them in the Plan and the Option Agreement. 
  
  
 Pursuant to Belgian tax legislation and the
current interpretation thereof by the Belgian Minister of Finance, the Optionee may have two alternatives as to how the Option will be taxed. 
  

	 	1.	 Taxation at Offer Date 



	 	2.	 Taxation at Date of Exercise 


 The Optionee should consult his or her personal tax advisor before deciding which alternative he or she should select with respect to this offer. The choice is at the Optionee’s risk and Fortinet may not be held liable for damages,
if any, that the Optionee may incur should the Minister of Finance’s interpretation not be upheld. 
  

	1.	 Taxation at Offer Date: Example 


 Under the first alternative (which is based on the Law of March 26, 1999), the Option will be taxed at the time of the offer, [insert date] (“Offer Date”). 
 To obtain this tax treatment, the Optionee must expressly accept the Option within 60 days of the Offer Date by returning the executed Stock Option
Agreement to Fortinet by the end of this period. 
 Assuming the Option is exercised before January 1, 2013 and the Option has a term of
seven (7) years, the taxable value is the number of shares covered by the Option times the value of the underlying shares on the Offer Date times 17%, plus any increase in the value of Fortinet Common Stock on the Offer Date over the Exercise
Price (i.e., any amount by which the Option is “in the money” on the Offer Date). 







 For Belgian tax purposes, the fair market value of the shares of Fortinet Common Stock on the Offer Date
is the fair market value of the shares of Fortinet Common Stock as established by Fortinet’s Board of Directors as of such date. 
 For example,
assume the following facts: 

	 	•	 	 The Optionee is granted an Option for 100 shares of Fortinet Common Stock with an Exercise Price of US$10. 



	 	•	 	 The Option has a seven (7) year term. 



	 	•	 	 The fair market value of the shares of Fortinet Common Stock on the Offer Date is US$11. 



	 	•	 	 As the Exercise Price (US$10) is lower than the fair market value of the underlying share on the Offer Date (US$11), the excess of the market value over the
Exercise Price is added to the taxable value of the option. 



	 	•	 	 Assume the Optionee’s marginal tax rate is 50%. 


 Based on these facts, the Optionee’s Belgian tax liability for the 2009 income year as a consequence of the grant of the Option would be as follows: 
  

					
	 100 shares x US$11/share x 17% x 50%
	  	=	  	 US$93.50

			
	 100 shares x (US$11 - US$10) x 50%
	  	=	  	 US$50

			
	 Tax liability for 2009 income year
	  	=	  	 US$143.50 (this amount will need to be converted into Euros)


 The income tax is due even if the Optionee never exercises the Option or if the Optionee
becomes a non-resident of Belgium before the Optionee exercises the Option. 
 An exception to the general taxation rule is
available; the exception would result in favorable tax treatment by reducing the percentage factor from 17% to 8.5% (assuming a 7 year term). To qualify for the favorable tax treatment, the Optionee should execute an
“Undertaking” (a sample document is attached to this Supplement) not to exercise any portion of the Option before the end of the third full calendar year following the calendar year of the Offer Date. 
 Assume the same facts used in the example above, except that the Optionee has executed an Undertaking not to exercise any portion of the Option before
January 1, 2013. Under this exception, the Optionee’s tax liability for the 2013 income year would be $96.75. The calculation would be as follows: 
  

					
	 100 shares x US$11/share x 8.5% x 50%
	  	=	  	 US$46.75

			
	 100 shares x (US$11 - US$10) x 50%
	  	=	  	 US$50

			
	 Tax liability for 2009 income year
	  	=	  	 US$96.75 (this amount will need to be converted into Euros)


 The income tax is due even if the Optionee never exercises the Option or if the Optionee
becomes a non-resident of Belgium before the Optionee exercises the Option. 
 If the Option is taxed under this first alternative,
the Optionee will not be subject to tax when the Optionee subsequently exercises the Option and purchase shares of Fortinet Common Stock under the Plan, unless the Optionee exercises the Option before the date specified in the Optionee’s
Undertaking. 
 Finally, the Optionee should note that the Optionee may also decide to reject the Option within 60 days of the Offer Date, in
which case the Optionee will not incur any tax liability (neither under the first alternative nor under the second alternative, discussed below). However, if Optionee rejects the Option (or does not expressly accept the Option), his or her Option
will be cancelled and he or she will get no benefit from the Option or any benefits/compensation in lieu of the cancelled Option. 








	2.	 Taxation at Date of Exercise: Example 


 Under the second alternative, if the Optionee accepts the Option more than 60 days after the Offer Date, the Option will be taxed only upon exercise. This tax treatment is based on a current interpretation of Belgian
tax legislation by the Belgian Minister of Finance, which could subsequently be overturned by a court or by the Belgian legislature. Fortinet will not be liable/responsible in any way if taxation at exercise is not achieved as a result in a change
in tax law or interpretation thereof. 
 If the Option is subject to tax at exercise, tax will have to be paid on the difference (or spread)
between the fair market value of the shares at exercise and the Exercise Price. Assuming the same facts as in Example 1 above, that the Exercise Price is US$10, Optionee is granted an Option over 100 shares and the Optionee’s marginal tax rate
is 50% and further assuming that the fair market value of the shares at exercise is US$15 and Optionee exercises all of the optioned shares, Optionee would pay tax in the amount of US$250 [($15 - 10) x 100 shares x 50%]. (This amount will need to be
converted into Euros.) 
 To choose this tax treatment, the Optionee must accept the grant in writing more than 60 days but no later than
the time the Option is exercised from the Offer Date by returning the executed Stock Option Agreement to Fortinet. If the Optionee elects this tax treatment, there is no reason for the Optionee to sign the Undertaking. 
 General Tax Information 
 Taxation at Date of Sale 

 Regardless of when the Optionee accepts his or her offer, the Optionee will not be subject to tax when the Optionee sells shares acquired
under the Plan. 
 Social Security Contributions 
 Under the first alternative (i.e., Taxation at Offer Date), the Optionee may be subject to social security contributions if the Exercise Price is lower than the market value of the underlying shares on the Offer Date, as determined
according to Belgian tax law, in which case the Optionee could be subject to social security contributions on such difference (or “discount”) between the Exercise Price and the market value of the shares on the Offer Date. However, even if
a discount exists, there are arguments which support the position that the discount should not be subject to social security contributions, unless the Optionee’s employer reimburses Fortinet for the costs of the Option or is otherwise involved
in the administration of the Plan (neither of which is currently the case)[please confirm]. 
 Under the second alternative
(i.e., Taxation at Date of Exercise), there are also arguments which support the position that the spread realized upon exercise of the Option should not be subject to social security contributions, unless the Optionee’s employer
reimburses Fortinet for the costs of the Option or Fortinet has not granted the Option at its own discretion (neither of which is currently the case) [please confirm]. However, this is not certain, and the Optionee should confirm his or her
social security liability with his or her personal tax advisor before the Optionee exercise the Option. 
 Tax Withholding and Reporting 

Under the first alternative, the Optionee’s employer is required to report the taxable amount at the time of the Offer Date on a 281.10 salary
form and a 325.10 recapitulative statement that will be given to the Optionee. In addition, the Optionee is responsible for reporting the grant of the Option on the Optionee’s annual tax return. It is the Optionee’s responsibility to pay
any taxes due when the Option is offered to the Optionee. 







 Under the second alternative, the Optionee’s employer should not be required to report or withhold
any taxes. The Optionee is responsible for reporting the grant and exercise of the Option on the Optionee’s annual return and to pay any taxes due as a result of the exercise of the Option. 
 Regardless of the tax treatment, the Optionee also may be required to report any security or bank account the Optionee hold outside of Belgium on the
Optionee’s annual tax return. 
 Accepting the Offer of the Option 
 If the Optionee decides to accept the Option, the Optionee has to indicate the Optionee’s acceptance by executing the Stock Option Agreement where noted and returning it in its entirety
to: 
 [Insert individual’s name] 
 Fortinet, Inc. 
 [insert address] 
 If the Optionee elects to fall under the first
alternative, the Optionee should return the executed Stock Option Agreement as soon as possible, but no later than [insert date] (i.e., 60 days after the Offer Date).  
 If the Optionee decides to execute the document entitled “Undertaking,” the Optionee must retain the original executed document for submission
with the Optionee’s applicable tax return and send a copy of the document to Fortinet with the Optionee’s executed Stock Option Agreement. 
 As explained above, if the Optionee accepts the offer under the first alternative, the Optionee must pay income tax even if the Optionee never ultimately benefit from the Option. For example, this could occur if the
Optionee terminates his or her employment with Fortinet before the Option vests or before the Option is exercised. In addition, the Option could become valueless due to a drop in the value of Fortinet Common Stock, which is not followed by a
sufficient recovery before the end of the option term. 
 If the Optionee elects to fall under the second alternative, the Optionee
should return the executed Stock Option Agreement (for Employees in Belgium) after [insert date] (i.e., 60 days after the Offer Date), but no later than the date the Option is exercised. There is no
need to execute the Undertaking in this case. 
 If the Optionee does not expressly accept the Option by signing the Stock Option
Agreement where noted and returning it to Fortinet, the Option will be deemed rejected and cancelled. If the Option is deemed rejected, the Optionee will not be subject to tax, but the Optionee will not receive any benefit from the Option or any
benefit/compensation in lieu of the cancelled Option.
