Ladies and Gentlemen:

FireEye, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several purchasers named in Schedule I hereto (the “Initial Purchasers”), for whom you are acting as representatives (the “Representatives”), $400,000,000 principal amount of its 1.000% Convertible Senior Notes Due 2035 (the “Series A Notes”) and $400,000,000 principal amount of its 1.625% Convertible Senior Notes due 2035 (the “Series B Notes,” and together with the Series A Notes, the “Firm Securities”). The Series A Notes will be issued pursuant to the provisions of an indenture to be dated as of the Closing Date (as defined below) (the “Series A Indenture”) between the Company and U.S. Bank National Association, as Trustee (the “Trustee”), and the Series B Notes will be issued pursuant to the provisions of an indenture to be dated as of the Closing Date (the “Series B Indenture,” and together with the Series A Indenture, the “Indentures”) between the Company and the Trustee. The Company also proposes to issue and sell to the Initial Purchasers not more than an additional $60,000,000 principal amount of its Series A Notes and an additional $60,000,000 principal amount of its Series B Notes (together, the “Additional Securities”) if and to the extent that you, as Representatives of the offering, shall have determined to exercise, on behalf of the Initial Purchasers, the right to purchase such Additional Securities granted to the Initial Purchasers in Section 2 hereof. The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities.” The Securities will be convertible into cash, shares of the Company’s Common Stock, par value $0.0001 per share (the “Underlying Securities”), or a combination of cash and Underlying Securities, at the Company’s option.

The Securities and the Underlying Securities will be offered without being registered under the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act.

In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum (the “Preliminary Memorandum”) and will prepare a final offering memorandum (the “Final Memorandum”) including or incorporating by reference a description of the terms of the Securities and the Underlying Securities, the terms of the offering and a description of the Company. For purposes of this Agreement, “Additional Written Offering Communication” means any written communication (as defined in Rule 405 under the Securities Act) that constitutes an offer to sell or a solicitation of an offer to buy the Securities other than the Preliminary Memorandum or the Final Memorandum; “Time of Sale Memorandum” means the Preliminary Memorandum together with each Additional Written Offering Communication or other information, if any, each identified in Schedule II hereto under the caption Time of Sale Memorandum; and “General Solicitation” means any offer to sell or solicitation of an offer to buy the Securities by any form of general solicitation or advertising (as those terms are used in Regulation D under the Securities Act). As used herein, the terms Preliminary Memorandum, Time of Sale Memorandum and Final Memorandum shall include the documents, if any, incorporated by reference therein on the date hereof. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum or any Additional Written Offering Communication shall include all documents subsequently filed by the Company with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein.

The Company and its subsidiaries have good and marketable title to all personal property owned by them which is material to the business of the Company and its subsidiaries taken as a whole, in each case free and clear of all liens, encumbrances and defects except such as are described in the Time of Sale Memorandum or such as do not materially diminish the value of such property and do not materially interfere with the use made and

proposed to be made of such property by the Company and its subsidiaries; and any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid, subsisting and, to the Company’s knowledge, enforceable leases with such exceptions as are not material and do not materially interfere with the use made and proposed to be made of such property and buildings by the Company and its subsidiaries, in each case except as described in the Time of Sale Memorandum.

Except as disclosed in the Time of Sale Memorandum, or as would not, individually or in the aggregate, have a material adverse effect on the Company and its subsidiaries, taken as a whole: (i) to the Company’s knowledge, there are no third parties who have been able to establish any material rights to any Company Intellectual Property, except for the retained rights of the owners of the Company Intellectual Property that is licensed to the Company; (ii) there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others (A) challenging the validity, enforceability or scope of any Company Intellectual Property or (B) challenging the Company’s rights or any of its subsidiaries’ rights in or to any Company Intellectual Property; and (iii) there is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others that the Company or any of its subsidiaries materially infringes or misappropriates any intellectual property or other proprietary rights of others, and neither the Company nor any of its subsidiaries is aware of any fact which would form a reasonable basis for any such action, suit, proceeding or claim.

(gg) No material labor dispute with the employees of the Company or any of its subsidiaries exists, except as described in the Time of Sale Memorandum, or, to the knowledge of the Company, is imminent; and the Company is not aware of any existing, threatened or imminent labor disturbance by the employees of any of its principal suppliers, manufacturers or contractors that could have a material adverse effect on the Company and its subsidiaries, taken as a whole.

(hh) The Company and each of its subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are, in the Company’s reasonable judgment, prudent and customary in the businesses in which they are engaged; neither the Company nor any of its subsidiaries has been refused any insurance coverage sought or applied for; and neither the Company nor any of its subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not be reasonably likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, except as described in the Time of Sale Memorandum.

(ii) The Company and its subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except where the failure to obtain such certificates, authorizations or permits would not, individually or in the aggregate, be reasonably likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a material adverse effect on the Company and its subsidiaries, taken as a whole, except as described in the Time of Sale Memorandum.

(jj) The Company has timely made all filings required to be made by it pursuant to the Exchange Act, and the rules and regulations promulgated thereunder.

2. Agreements to Sell and Purchase. The Company hereby agrees to sell to the several Initial Purchasers, and each Initial Purchaser, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Firm Securities set forth in Schedule I hereto opposite its name at a purchase price of 97.50% of the principal amount thereof (the “Purchase Price”) plus accrued interest, if any, to the Closing Date.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Initial Purchasers the Additional Securities, and the Initial Purchasers shall have the right to purchase, severally and not jointly, up to $60,000,000 principal amount of Series A Notes and up to $60,000,000 principal amount of Series B Notes, in each case representing the Additional Securities at the Purchase Price plus accrued interest, if any, to the date of payment and delivery. The Representatives may exercise this right on behalf of the Initial Purchasers in whole or from time to time in part by giving written notice to the Company; provided that any Option Closing Date (as defined below) shall occur within a period (the “Exercise Period”) of thirteen calendar days from, and including, the Closing Date. Any exercise notice shall specify the principal amount of Additional Securities to be purchased by the Initial Purchasers and the date on which such Additional Securities are to be purchased. Each purchase date must be within the Exercise Period, and must be at least one business day after the written notice is given and may not be earlier than the closing date for the Firm Securities nor later than five business days after the date of such notice. On each day, if any, that Additional Securities are to be purchased (an “Option Closing Date”), each Initial Purchaser agrees, severally and not jointly, to purchase the principal amount of Additional Securities (subject to such adjustments to eliminate fractional Securities as the Representatives may determine) that bears the same proportion to the total principal amount of Additional Securities to be purchased on such Option Closing Date as the principal amount of Firm Securities set forth in Schedule I opposite the name of such Initial Purchaser bears to the total principal amount of Firm Securities.

3. Terms of Offering. The Representatives have advised the Company that the Initial Purchasers will make an offering of the Securities purchased by the Initial Purchasers hereunder as soon as practicable after this Agreement is entered into as in their judgment is advisable.

4. Payment and Delivery. Payment for the Firm Securities shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Firm Securities for the respective accounts of the several Initial Purchasers at 10:00 a.m., New York City time, on June 2, 2015, or at such other time on the same or such other date, not later than June 9, 2015, as shall be designated in writing by the Representatives. The time and date of such payment are hereinafter referred to as the “Closing Date.”

Payment for any Additional Securities shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Additional Securities for the respective accounts of the several Initial Purchasers at 10:00 a.m., New York City time, on the date specified in the corresponding notice described in Section 2 or at such other time on the same or on such other date, in any event not later than the last day of the Exercise Period, as shall be designated in writing by the Representatives.

The Securities shall be in definitive form or global form, as specified by the Representatives, and registered in such names and in such denominations as the Representatives shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Securities shall be delivered to the Representatives on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Initial Purchasers, with any transfer taxes payable in connection with the transfer of the Securities to the Initial Purchasers duly paid, against payment of the Purchase Price therefor plus accrued interest, if any, to the date of payment and delivery.

5. Conditions to the Initial Purchasers’ Obligations.

(a) The several obligations of the Initial Purchasers to purchase and pay for the Firm Securities on the Closing Date are subject to the following conditions:

(i) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date:

(A) there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the securities of the Company or any of its subsidiaries by any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act; and

(B) there shall not have occurred or shall exist any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Memorandum provided to the prospective purchasers of the Securities that, in the Representatives’ judgment, is material and adverse and that makes it, in the Representatives’ judgment, impracticable or inadvisable to market the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum.

(C) The Representatives shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in Section 5(a)(i)(A) and to the effect that the representations and warranties of the Company contained in this Agreement are true and

It is understood, however, that except as provided in this Section 6(h), Section 8 (Indemnity and Contribution), and the last paragraph of Section 10, the Initial Purchasers will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Securities by them and any advertising expenses connected with any offers they may make.

(i) Neither the Company nor any Affiliate will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) which could be integrated with the sale of the Securities in a manner which would require the registration under the Securities Act of the Securities.

(j) To furnish the Representatives with any proposed General Solicitation to be made by the Company or on its behalf before its use, and not to make or use any proposed General Solicitation without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and ▇.▇. ▇▇▇▇▇▇ Securities LLC.

(k) While any of the Securities or the Underlying Securities remain “restricted securities” within the meaning of the Securities Act, to make available, upon request, to any seller of such Securities the information specified in Rule 144A(d)(4) under the Securities Act, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act.

(l) During the period of one year after the Closing Date or any Option Closing Date, if later, the Company will not be, nor will it become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act.

(m) Until all restrictive legends have been removed from the Securities, the Company will not, and will not permit any of its controlled “affiliates” (as defined in Rule 144 under the Securities Act (“Rule 144”)) to resell any of the Securities or the Underlying Securities issuable upon conversion of the Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them (other than pursuant to a registration statement or exemption from registration under the Securities Act that results in such securities not constituting “restricted securities” under Rule 144).

(n) Not to take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby.

The Company also agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC on behalf of the Initial Purchasers, it will not, during the period ending 90 days after the date of the Final Memorandum (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) the sale of the Securities under this Agreement or any issuance of Underlying Securities upon conversion thereof, (b) the issuance by the Company of any shares of common stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof of which the Initial Purchasers have been advised in writing or for which a filing has been made under Section 16(a) of the Exchange Act, (c) the grant of options or the issuance of shares of

common stock by the Company to employees, officers, directors, advisors or consultants of the Company pursuant to employee benefit plans in effect on the date hereof, (d) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of common stock, provided that (A) such plan does not provide for the transfer of common stock during the Restricted Period and (B) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of common stock may be made under such plan during the Restricted Period, (e) the sale or issuance of or entry into an agreement to sell or issue shares of common stock or securities convertible into or exercisable for common stock in connection with any (i) merger, (ii) acquisition of securities, businesses, property or other assets, (iii) joint ventures, (iv) strategic alliances, (v) equipment leasing arrangements or (vi) debt financing, provided, that the aggregate number of shares of common stock, or securities convertible into or exercisable for common stock, (on an as-converted or as-exercised basis, as the case may be) that the Company may sell or issue or agree to sell or issue pursuant to this clause (e) shall not exceed 10% of the total number of shares of the common stock issued and outstanding immediately following the completion of the transactions contemplated by this Agreement, and provided further, that each recipient of shares of common stock or securities convertible into or exercisable for common stock pursuant to this clause (e) shall execute a lock-up agreement substantially in the form of Exhibit B hereto. For the avoidance of doubt, the restrictions in this paragraph do not apply to the Company’s entry into and performance under or termination of the Prepaid Forward Agreements.

7. Offering of Securities; Restrictions on Transfer. Each Initial Purchaser, severally and not jointly, represents and warrants and agrees that:

(a) It is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”) and an accredited investor within the meaning of Rule 501(a) of Regulation D under the Securities Act;

(b) It has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Securities by any General Solicitation, other than a permitted communication listed on Schedule II hereto, or those made with the prior written consent of the Company, or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act;

(c) It has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Securities except within the United States to persons that it reasonably believes to be QIBs in transactions pursuant to Rule 144A under the Securities Act, and that, in each case, in purchasing Securities, is deemed to have represented and agreed as provided in the Final Memorandum under the caption “Transfer Restrictions.”

8. Indemnity and Contribution.

(a) The Company agrees to indemnify and hold harmless each Initial Purchaser, each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged

untrue statement of a material fact contained in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Offering Communication prepared by or on behalf of, used by, or referred to by the Company, any General Solicitation made by the Company, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Final Memorandum or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Offering Communication set forth in Schedule II hereto, road show, General Solicitation set forth in Schedule II hereto, the Final Memorandum or any amendment or supplement thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party, or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and ▇.▇. ▇▇▇▇▇▇ Securities LLC, in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by

reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses but after deducting discounts and commissions) received by the Company and the total discounts and commissions received by the Initial Purchasers bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and of the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e) The Company and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price of the Securities distributed by such Initial Purchaser in the offering exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or

alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9. Termination. The Initial Purchasers may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Memorandum.

10. Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, or an Option Closing Date, as the case may be, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Firm Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Firm Securities which it has or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory

to the Representatives and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or of the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Final Memorandum or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Additional Securities and the aggregate principal amount of Additional Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Additional Securities to be purchased on such Option Closing Date, the non-defaulting Initial Purchasers shall have the option to (a) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Option Closing Date or (b) purchase not less than the principal amount of Additional Securities that such non-defaulting Initial Purchasers would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If this Agreement shall be terminated by the Initial Purchasers, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Initial Purchasers or such Initial Purchasers as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with this Agreement or the offering contemplated hereunder.

11. Entire Agreement.

(a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and the Initial Purchasers with respect to the preparation of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b) The Company acknowledges that in connection with the offering of the Securities: (i) the Initial Purchasers have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Initial Purchasers owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement) if any, and (iii) the Initial Purchasers may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Initial Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement, and any claim, controversy or dispute relating to or arising out of this Agreement, shall be governed by and construed in accordance with the internal laws of the State of New York.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Initial Purchasers shall be delivered, mailed or sent to the Representatives in care of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Convertible Debt Syndicate Desk, with a copy to the Legal Department; and, in care of ▇.▇. ▇▇▇▇▇▇ Securities LLC, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, fact (▇▇▇) ▇▇▇-▇▇▇▇); Attention: Equity Syndicate Desk; and if to the Company shall be delivered, mailed or sent to FireEye, Inc., ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: General Counsel, with a copy to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇ Professional Corporation, ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇ ▇▇▇▇▇ and ▇▇▇ ▇▇▇▇▇.

OPINION OF COUNSEL FOR THE COMPANY

On the basis of the foregoing and in reliance thereon and subject to the limitations and qualifications set forth herein, we are of the opinion that:

The Company is a corporation duly incorporated and validly existing under the laws of the State of Delaware and is in good standing under such laws. The Company has requisite corporate power to own or lease its properties and carry on its business, as described in the Final Offering Memorandum. The Company is qualified to do business and is in good standing as a foreign corporation in the State of California.

The execution and delivery of the Operative Documents have been duly authorized by all necessary corporate action on the part of the Company, and the Purchase Agreement has been duly executed and delivered by the Company.

The Company has the corporate power to execute and deliver the Operative Documents and to perform its obligations under the terms of the Operative Documents.

The authorized capital stock of the Company is as set forth in the Final Offering Memorandum under the caption “Description of Capital Stock.” The Securities being issued on the date hereof are in the form contemplated in the applicable Indenture and have been duly authorized by all necessary corporate action of the Company and have been duly executed by the Company and when authenticated by the Trustee in accordance with the terms of the applicable Indenture (which authentication we have not determined by inspection of the Securities) and issued and delivered to the Initial Purchasers against payment of the purchase price therefor specified in the Purchase Agreement, the Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

Each Indenture has been duly authorized by all necessary corporate action on the part of the Company and each Indenture has been duly executed and delivered by the Company and each Indenture constitutes a valid and binding instrument, enforceable against the Company in accordance with its terms.

The shares of Common Stock initially issuable upon conversion of the Securities (assuming full physical settlement of the Securities of each series and including shares of Common Stock issuable with respect to any Make-Whole Fundamental Change (as defined in the applicable Indenture)) (the

A-1

“Shares”) have been duly authorized and reserved by all necessary corporate action on the part of the Company and the Shares, if any, when issued upon due conversion of the applicable Securities in accordance with the terms of such Securities and the applicable Indenture would, if issued today, be validly issued, fully paid and nonassessable and free of preemptive rights arising under the Certificate of Incorporation or Bylaws or the DGCL.

The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Description of Notes” insofar as such statements purport to constitute a summary of the terms of the Indentures and the Securities, fairly summarize such terms in all material respects.

The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Certain U.S. Federal Income Tax Considerations,” insofar as they purport to summarize the United States federal tax laws referred to therein or legal conclusions with respect thereto, are fair summaries in all material respects.

The statements set forth in the General Disclosure Package and Final Offering Memorandum under the caption “Description of Capital Stock,” insofar as such statements constitute summaries of legal matters or documents, fairly summarize the matters and documents referred to therein in all material respects.

10.

The Company is not, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the General Disclosure Package, will not be required to be registered as, an “investment company,” as such term is defined in the Investment Company Act.

11.

None of the issuance and sale of the Securities being delivered on the date hereof, the execution, delivery and performance by the Company of its obligations under the Purchase Agreement, the Indentures and the Securities or the consummation of the transactions contemplated thereby will (i) violate the Certificate of Incorporation or Bylaws, (ii) conflict with, result in a breach or violation by the Company of any of the terms or provisions of, or constitute a default by the Company under any Reviewed Agreement, (iii) result in a violation of any Reviewed Judgment, or (iv) contravene any applicable law.

12.

No consent, approval, authorization, order, registration or qualification of or with any U.S. federal, New York, California or Delaware (solely with respect to the DGCL) governmental agency or body or court is required for the execution and delivery of the Purchase Agreement, the offer, sale or issuance by the Company of the Securities or the consummation by the

A-2

Company of the transactions contemplated by the Purchase Agreement or the Indentures, except (i) such as have been obtained under the Securities Act, (ii) such as may be required under state securities or Blue Sky laws, and (iii) as contemplated by the Operative Documents.

13.

Assuming the accuracy of the Initial Purchasers’ representations contained in the Purchase Agreement and the accuracy of the Company’s representations contained in the Purchase Agreement, no registration of the Securities or the Shares is required under the Securities Act for the sale of the Securities by the Company to the Initial Purchasers pursuant to the Purchase Agreement and the Indentures or for the initial resale of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the General Disclosure Package and the Final Offering Memorandum, and it is not necessary to qualify the Indentures under the Trust Indenture Act (it being understood that, in each case, no opinion is expressed as to any subsequent resale of the Securities or the consequences thereof).

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”) and ▇.▇. ▇▇▇▇▇▇ Securities LLC propose to enter into a Purchase Agreement (the “Purchase Agreement”) with FireEye, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) by the several initial purchasers who are parties thereto, including ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇.▇. ▇▇▇▇▇▇ Securities LLC (collectively, the “Initial Purchasers”), of Convertible Senior Notes due 2035 of the Company (the “Series A Notes”) and Convertible Senior Notes due 2035 of the Company (the “Series B Notes,” and together with the Series A Notes, the “Securities”). Subject to the terms and conditions set forth in the Purchase Agreement, the Securities will be convertible into shares of the Common Stock (par value $0.0001 per share) of the Company (the “Common Stock”).

To induce the Initial Purchasers that may participate in the Offering to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Initial Purchasers, the undersigned will not, during the period commencing on the date hereof and ending 90 days after the date of the final offering memorandum (the “Restricted Period”) relating to the Offering (the “Final Memorandum”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of

B-1

the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.

The restrictions described in the foregoing paragraph shall not apply to:

(a) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock (i) to the spouse, domestic partner, parent, sibling, child or grandchild (each, an “immediate family member”) of the undersigned or to a trust formed for the benefit of the undersigned or of an immediate family member of the undersigned, (ii) by bona fide gift, will or intestacy, (iii) if the undersigned is a corporation, partnership, limited liability company or other business entity (A) to another corporation, partnership, limited liability company or other business entity that controls, is controlled by or is under common control with the undersigned or (B) as part of a disposition, transfer or distribution by the undersigned to its equity holders, or (iv) if the undersigned is a trust, to a trustor or beneficiary of the trust; provided that in the case of any transfer or distribution pursuant to this clause (a), (i) each transferee, donee or distributee shall sign and deliver a lock-up agreement substantially in the form of this agreement prior to or upon such transfer or distribution, and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction of beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Restricted Period;

(b) (i) the receipt by the undersigned from the Company of shares of Common Stock upon the exercise of options, insofar as such option is outstanding as of the date of the Final Memorandum, (ii) the transfer of shares of Common Stock or any securities convertible into Common Stock to the Company upon a vesting event of the Company’s securities, including, without limitation, restricted stock units, or upon the exercise of options or warrants to purchase the Company’s securities on a “cashless” or “net exercise” or “net issuance” basis to cover tax withholding obligations of the undersigned in connection with such vesting or exercise, or (iii) the sale of shares of Common Stock underlying outstanding restricted stock units to cover the payment of tax withholding obligations upon the vesting of such awards, provided that in the case of either (i) or (ii), no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made within 30 days after the date of the Final Memorandum, and after such 30th day, any filing under Section 16(a) of the Exchange Act shall clearly indicate in the footnotes thereto that (a) the filing relates to the circumstances described in (i) or (ii), as the case may be, (b) no shares were sold by the reporting person and (c) in the case of (i), the shares received upon exercise of the option are subject to a lock-up agreement with the Initial Purchasers of the Offering;

(c) the transfer of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to the Company pursuant to agreements under which the shares were issued and the Company has the option to repurchase such shares or securities or a right of first refusal with respect to transfers of such shares or securities, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made within 30 days after the date of the Final Memorandum, and after such 30th day, any filing under Section 16(a) of the Exchange Act shall clearly indicate in the footnotes thereto that (i) the filing relates to the transfer of such shares or securities to the Company pursuant to such repurchase option or right of first refusal, as the case may be, and (ii) no shares were sold by the reporting person;

(d) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”) for the transfer of shares of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock during the Restricted Period and (ii) to the extent a

B-2

public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period;

(e) the transfer of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock that occurs solely by operation of law or by order of a court of competent jurisdiction, provided that the transferee shall sign and deliver a lock-up agreement substantially in the form of this agreement;

(f) the disposition by the undersigned of shares of Common Stock purchased from the Company pursuant to any employee stock purchase plan filed with the Securities and Exchange Commission prior to the date hereof, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the Restricted Period; or

(g) sales of Common Stock made pursuant to a trading plan pursuant to Rule 10b5-1 that has been entered into by the undersigned prior to the date of this agreement; provided, that to the extent a public announcement or filing under the Exchange Act, if any, is required or voluntarily made by or on behalf of the undersigned or the Company regarding any such sales, such announcement or filing shall include a statement to the effect that the sale was effected pursuant to a trading plan pursuant to Rule 10b5-1.

In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Initial Purchasers, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

This agreement shall automatically terminate upon the earliest to occur, if any, of (a) the date the Company advises the Representatives, in writing, prior to the execution of the Purchase Agreement, that it has determined not to proceed with the Offering, (b) the date of the termination of the Purchase Agreement if prior to the closing of the Offering, (c) August 15, 2015, if the Purchase Agreement has not been executed by that date, or (d) the consummation of a bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of the Common Stock involving a change of control of the Company (as defined below), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Common Stock owned by the undersigned shall remain subject to the restrictions contained in this agreement. For the purposes of the immediately preceding sentence, a “change of control” means the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than the Initial Purchasers pursuant to the Offering), of shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock if, after such transfer, the stockholders of the Company immediately prior to such transfer do not own at least twenty percent (20%) of the outstanding voting securities of the Company (or the surviving entity).

B-3

The undersigned understands that the Company and the Initial Purchasers are relying upon this agreement in proceeding toward consummation of the Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.

Very truly yours,

(Name)
