REGISTRATION RIGHTS AGREEMENT

This REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is entered into as of December 11, 2020, by and between FireEye, Inc., a Delaware corporation (including its successors and permitted assigns, the “Company”), and Blackstone Delta Holdings DE L.P., a Delaware limited partnership (formerly known as BTO Delta Holdings DE L.P.) (the “Investor”). Capitalized terms used but not defined elsewhere herein are defined in Exhibit A.

This Agreement is entered into in connection with the closing of the issuance of 370,000 shares of Series A Convertible Preferred Stock, which are convertible into shares of Common Stock, pursuant to the Securities Purchase Agreement, dated as of November 18, 2020, as amended by that certain Amendment to the Securities Purchase Agreement, dated as of December 11, 2020, by and between the Company and the Investor (the “Securities Purchase Agreement”).

As a condition to each of the parties’ obligations under the Securities Purchase Agreement, the Company and the Investor are entering into this Agreement for the purpose of granting certain registration rights to the Investor.

In consideration of the promises and the mutual representations, warranties, covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

ARTICLE I

RESALE SHELF REGISTRATION

Section 1.1    Resale Shelf Registration Statement. Subject to the other applicable provisions of this Agreement, the Company shall file within ninety (90) days of the date hereof and use its commercially reasonable efforts to cause to go effective as promptly as practicable a registration statement covering the sale or distribution from time to time by the Holders, on a delayed or continuous basis pursuant to Rule 415 of the Securities Act of all of the Registrable Securities on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, then such registration shall be on another appropriate form (including Form S-1) and shall provide for the registration of such Registrable Securities for resale by such Holders in accordance with any reasonable method of distribution elected by the Holders) (the “Resale Shelf Registration Statement” and such registration, the “Resale Shelf Registration”), and if the Company is a WKSI as of the filing date, the Resale Shelf Registration Statement shall be an Automatic Shelf Registration Statement. If the Resale Shelf Registration Statement is not an Automatic Shelf Registration Statement, then the Company shall use its commercially reasonable efforts to cause such Resale Shelf Registration Statement to be declared effective by the Commission as promptly as practicable after the filing thereof.

Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the Registrable Securities on the Resale Shelf Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities by the Holders, the Resale Shelf Registration Statement shall register the resale of a number of shares of the Registrable Securities which is equal to the maximum number of shares as is permitted by the Commission, and, subject to the provisions of this Section 1.1, the Company shall continue to its use commercially reasonable efforts to register all remaining

1

Registrable Securities as set forth in this Section 1.1. In such event, the number of shares of Registrable Securities to be registered for each Holder in the Resale Shelf Registration Statement shall be reduced pro rata among all Holders, provided, however, that, prior to reducing the number of shares of Registrable Securities to be registered for any Holder in such Resale Shelf Registration Statement, the Company shall first remove any shares of Registrable Securities to be registered for any Person other than a Holder that was proposed to be included in such Resale Shelf Registration Statement. The Company shall continue to use its commercially reasonable efforts to register all remaining Registrable Securities as promptly as practicable in accordance with the applicable rules, regulations and guidance of the Commission. Notwithstanding anything herein to the contrary, if the Commission, by written comment, limits the Company’s ability to file, or prohibits or delays the filing of, a Resale Shelf Registration Statement or a Subsequent Shelf Registration with respect to any or all the Registrable Securities, the Company’s compliance with such limitation, prohibition or delay solely to the extent of such limitation, prohibition or delay shall not be a breach or default by the Company under this Agreement and shall not be deemed a failure by the Company to use “commercially reasonable efforts” or “reasonable efforts” as set forth above or elsewhere in this Agreement.

Section 1.2    Effectiveness Period. Once effective, the Company shall, subject to the other applicable provisions of this Agreement, use its commercially reasonable efforts to cause the Resale Shelf Registration Statement or a Subsequent Shelf Registration to be continuously effective and usable for so long as any Registrable Securities remain outstanding (the “Effectiveness Period”).

Section 1.3    Subsequent Shelf Registration. If any Shelf Registration ceases to be effective under the Securities Act for any reason at any time during the Effectiveness Period, the Company shall use its commercially reasonable efforts to promptly cause such Shelf Registration to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration), and in any event shall within thirty (30) days of such cessation of effectiveness, amend such Shelf Registration in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of such Shelf Registration or, file an additional registration statement (a “Subsequent Shelf Registration”) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by Holders thereof of all securities that are Registrable Securities as of the time of such filing. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (a) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after such filing, but in no event later than the date that is ninety (90) days after such Subsequent Shelf Registration is filed and (b) keep such Subsequent Shelf Registration (or another Subsequent Shelf Registration) continuously effective until the end of the Effectiveness Period. Any such Subsequent Shelf Registration shall be a Registration Statement on Form S-3 to the extent that the Company is eligible to use such form, and if the Company is a WKSI as of the filing date, such Registration Statement shall be an Automatic Shelf Registration Statement. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form (including Form S-1) and shall provide for the registration of such Registrable Securities for resale by such Holders in accordance with any reasonable method of distribution elected by the Holders.

2

Section 1.4    Supplements and Amendments. The Company shall supplement and amend any Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration if required by the Securities Act or as reasonably requested by the Holders covered by such Shelf Registration.

Section 1.5    Subsequent Holder Notice. If a Person becomes a Holder of Registrable Securities after a Shelf Registration becomes effective under the Securities Act, the Company shall, as promptly as is reasonably practicable following delivery of written notice to the Company of such Person becoming a Holder and requesting for its name to be included as a selling securityholder in the prospectus related to the Shelf Registration (a “Subsequent Holder Notice”):

(a)    if required and permitted by applicable law, file with the Commission a supplement to the related prospectus or a post-effective amendment to the Shelf Registration so that such Holder is named as a selling securityholder in the Shelf Registration and the related prospectus in such a manner as to permit such Holder to deliver a prospectus to purchasers of the Registrable Securities in accordance with applicable law;

(b)    if, pursuant to Section 1.5(a), the Company shall have filed a post-effective amendment to the Shelf Registration that is not automatically effective, use its commercially reasonable efforts to cause such post-effective amendment to become effective under the Securities Act as promptly as is reasonably practicable, but in any event by the date that is ninety (90) days after the date such post-effective amendment is required by Section 1.5(a) to be filed; and

(c)    notify such Holder as promptly as is reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 1.5(a).

Section 1.6    Underwritten Offering. The Holders of Registrable Securities may on up to four (4) occasions after the Resale Shelf Registration Statement becomes effective deliver a written notice to the Company specifying that the sale of some or all of the Registrable Securities subject to the Shelf Registration is intended to be conducted through an underwritten offering, so long as the anticipated gross proceeds of such underwritten offering is not less than twenty-five million dollars ($25,000,000) (unless the Holders are proposing to sell all of their remaining Registrable Securities in which case no such minimum gross proceeds threshold shall apply) (the “Underwritten Offering”). In the event of an Underwritten Offering:

(a)    The Holder or Holders of a majority of the Registrable Securities participating in an Underwritten Offering shall select the managing underwriter or underwriters to administer the Underwritten Offering; provided that such Holder or Holders will not make the choice of such managing underwriter or underwriters without first consulting with the Company.

(b)    Notwithstanding any other provision of this Section 1.6, if the managing underwriter or underwriters of a proposed Underwritten Offering advises the Board of Directors of the Company that in its or their opinion the number of Registrable Securities requested to be included in such Underwritten Offering exceeds the number which can be sold in such

3

Underwritten Offering in light of market conditions, the Registrable Securities shall be included on a pro rata basis upon the number of securities that each Holder shall have requested to be included in such offering. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter or underwriters.

(c)    The Company shall agree and shall cause its executive officers and directors to sign a customary “lock-up” agreement with the underwriters in any Underwritten Offering.

Section 1.7    Take-Down Notice. Subject to the other applicable provisions of this Agreement, at any time that any Resale Shelf Registration Statement is effective, if a Holder delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to effect a sale or distribution of all or part of its Registrable Securities included by it on any Resale Shelf Registration Statement (a “Shelf Offering”) and stating the number of Registrable Securities to be included in such Shelf Offering, then, subject to the other applicable provisions of this Agreement, the Company shall, as promptly as practicable, amend or supplement the Resale Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be sold and distributed pursuant to the Shelf Offering.

ARTICLE II

COMPANY REGISTRATION

Section 2.1    Notice of Registration. If at any time or from time to time the Company shall determine to file a registration statement with respect to an offering (or to make an underwritten public offering pursuant to a previously filed registration statement) of its Common Stock, whether or not for its own account (other than a registration statement on Form S-4, Form S-8 or any successor forms), the Company will:

(a)    promptly give to each Holder written notice thereof, which notice shall be given, to the extent reasonably practicable, no later than five (5) business days prior to the filing or launch date (except in the case of an offering that is an “overnight offering”, in which case such notice must be given no later than two (2) business days prior to the filing or launch date); and

(b)    subject to Section 2.2, include in such registration or underwritten offering (and any related qualification under blue sky laws or other compliance) all the Registrable Securities specified in a written request or requests made within three (3) business days after receipt of such written notice from the Company by any Holder (except in the case of an offering that is an “overnight offering”, in which case such request must be made no later than one (1) business day after receipt of such written notice from the Company).

Section 2.2    Underwriting. The right of any Holder to registration pursuant to Section 1.6 or this Article II shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. Each Holder proposing to distribute its securities through such underwriting shall (together with the Company and the other holders distributing their securities through such

4

underwriting) enter into and perform such Holder’s obligations under an underwriting agreement with the managing underwriter selected for such underwriting by the Company or by the stockholders of the Company who have the right to select the underwriters (such underwriting agreement to be in a customary form negotiated by the Company or such stockholders, as the case may be). Notwithstanding any other provision of this Article II, if the managing underwriter or underwriters of a proposed underwritten offering with respect to which Holders of Registrable Securities have exercised their piggyback registration rights advise the Board of Directors of the Company that in its or their opinion the number of Registrable Securities requested to be included in the offering thereby and all other securities proposed to be sold in the offering exceeds the number which can be sold in such underwritten offering in light of market conditions, the Registrable Securities and such other securities to be included in such underwritten offering shall be allocated, (a) first, in the event such offering was initiated by the Company for its own account, up to the total number of securities that the Company has requested to be included in such registration, (b) second, and only if all the securities referred to in clause (a) have been included, up to the total number of securities that the Holders have requested to be included in such offering (pro rata based upon the number of securities that each of them shall have requested to be included in such offering) and (c) third, and only if all the securities referred to in clause (b) have been included, all other securities proposed to be included in such offering that, in the opinion of the managing underwriter or underwriters can be sold without having such adverse effect. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter or underwriters. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

Section 2.3    Right to Terminate Registration. The Company or the holders of securities who have caused a registration statement to be filed as contemplated by this Article II, as the case may be, shall have the right to have any registration initiated by it or them under this Article II terminated or withdrawn prior to the effectiveness thereof, whether or not any Holder has elected to include securities in such registration.

ARTICLE III

Such underwriter agrees that it shall, upon learning that disclosure of the Requested Information is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Requested Information deemed confidential;

(j)    in the event that any broker-dealer underwrites any Registrable Securities or participates as a member of an underwriting syndicate or selling group or “participates in an offering” (within the meaning of the FINRA Rules) thereof, whether as a Holder or as an underwriter, placement, sales agent or broker or dealer in respect thereof, or otherwise, the Company will, upon the reasonable request of such broker-dealer, comply with any reasonable request of such broker-dealer in complying with the FINRA Rules;

(k)    notwithstanding any other provision of this Agreement, if the Board of Directors of the Company has determined in good faith that the disclosure necessary for continued use of the prospectus and registration statement by the Holders could be materially detrimental to the Company, the Company shall have the right not to file or not to cause the effectiveness of any registration covering any Registrable Securities and to suspend the use of the prospectus and the registration statement covering any Registrable Security for such period of time as its use would be materially detrimental to the Company by delivering written notice of such suspension to all Holders listed on the Company’s records; provided, however, that in any

7

12-month period the Company may exercise the right to such suspension not more than four times. From and after the date of a notice of suspension under this Section 3.1(k), each Holder agrees not to use the prospectus or registration statement until the earlier of (i) notice from the Company that such suspension has been lifted or (ii) the day following the sixtieth (60^th) day of suspension within any 12-month period;

Section 3.2    Limitation on Subsequent Registration Rights. From and after the date hereof, the Company shall not enter into any agreement granting any holder or prospective holder of any securities of the Company registration rights with respect to such securities that conflict with the rights granted to the Holders herein, without the prior written consent of Holders of a majority of the Registrable Securities.

Section 3.3    Expenses of Registration. All Registration Expenses incurred in connection with any registration pursuant to this Agreement or otherwise in complying with this Agreement shall be borne by the Company. All Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of the registered securities included in such registration.

Section 3.4    Information by Holders. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders, the Registrable Securities held by them and the distribution proposed by such Holder or Holders as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. It is understood and agreed that the obligations of the Company under Article I or II are conditioned on the timely provisions of the foregoing information by such Holder or Holders and, without limitation of the foregoing, will be conditioned on compliance by such Holder or Holders with the following:

(a)    such Holder or Holders will cooperate with the Company in connection with the preparation of the applicable registration statement, and for so long as the Company is obligated to keep such registration statement effective, such Holder or Holders will provide to the Company, in writing and in a timely manner, for use in such registration statement (and

(b)    during such time as such Holder or Holders may be engaged in a distribution of the Registrable Securities, such Holder or Holders will comply with all laws applicable to such distribution, including Regulation M promulgated under the Exchange Act, and, to the extent required by such laws, will, among other things: (i) not engage in any stabilization activity in connection with the securities of the Company in contravention of such laws and (ii) if required by applicable law, cause to be furnished to each agent or broker-dealer to or through whom such Registrable Securities may be offered, or to the offeree if an offer is made directly by such Holder or Holders, such copies of the applicable prospectus (as amended and supplemented to such date) and documents incorporated by reference therein as may be required by such agent, broker-dealer or offeree; and

(c)    on receipt of written notice from the Company of the happening of any of the events specified in Section 3.1(k), or that requires the suspension by such Holder or Holders of the distribution of any of the Registrable Securities owned by such Holder or Holders pursuant to a registered offering, then such Holders shall cease offering or distributing the Registrable Securities owned by such Holder or Holders in a registered offering until the offering and distribution of the Registrable Securities owned by such Holder or Holders may recommence in accordance with the terms hereof and applicable law.

Section 3.5    Rule 144 Reporting. With a view to making available the benefits of Rule 144 to the Holders, the Company will use commercially reasonable efforts to:

(a)    file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(b)    so long as a Holder owns any Restricted Securities, furnish to the Holder forthwith upon written request a written statement by the Company as to its compliance with the reporting requirements of the Exchange Act.

Section 3.6    “Market Stand-Off” Agreement. The Holders shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to, any Common Stock (or other securities of the Company) held by the Holders (other than those included in the registration) for a period specified by the representatives of the managing underwriter or underwriters of Common Stock (or other securities of the Company convertible into Common Stock) not to exceed five (5) days prior and ninety (90) days following any registered public sale of securities by the Company in which such Holder participates in accordance with Article II, subject to customary exceptions (including, without limitation, to the extent that any securities of the Company are subject to a Permitted Loan (as defined in the Securities Purchase Agreement), to permit the pledge of such securities pursuant to such Permitted Loan and any foreclosure in connection with such Permitted Loan, or transfer in lieu of a foreclosure thereunder, and subsequent sales, dispositions or other transfers). Each of the Holders also shall execute and

9

deliver any “lock-up” agreement reasonably requested by the representatives of any underwriters of the Company in connection with an offering in which such Holder participates, subject to customary exceptions (including, without limitation, as described in the preceding sentence in respect of pledges and foreclosures).

Section 3.7    Discontinuation of Registration. Notwithstanding anything to the contrary in this Agreement, the Company may discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the registration statement relating thereto.

ARTICLE IV

INDEMNIFICATION

Section 4.1    Indemnification by Company. To the extent permitted by applicable law, the Company will, with respect to any Registrable Securities as to which registration or qualification or compliance under applicable “blue sky” laws has been effected pursuant to this Agreement, indemnify each Holder, each Holder’s current and former officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and employees, and each Person controlling such Holder or any of the foregoing within the meaning of Section 15 of the Securities Act, and each underwriter thereof, if any, and each Person who controls any such underwriter within the meaning of Section 15 of the Securities Act (collectively, the “Company Indemnified Parties”), against all expenses, claims, losses, damages, costs (including costs of preparation and reasonable attorney’s fees and any legal or other fees or expenses actually incurred by such party in connection with any investigation or proceeding), judgments, fines, penalties, charges, amounts paid in settlement and other liabilities, joint or several (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto incident to any such registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by the Company of, or any rule or regulation promulgated under, the Securities Act, Exchange Act or state securities laws applicable to the Company in connection with any such registration, and the Company will reimburse each of the Company Indemnified Parties for any reasonable legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred. The indemnity agreement contained in this Section 4.1 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the prior written consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable to a Holder in any such case for any such loss, claim, damage, liability or action (a) to the extent that it arises out of or is based upon a violation or alleged violation of any state or federal law (including any claim arising out of or based on any untrue statement or alleged untrue statement or omission or alleged omission in the registration statement or prospectus) which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by or on behalf of any Holder or (b) in the case of a sale directly by a Holder of Registrable Securities (including a sale of such Registrable Securities through any underwriter retained by such Holder engaging in a distribution solely on

10

behalf of such Holder), such untrue statement or alleged untrue statement or omission or alleged omission was corrected in a final or amended prospectus, and such Holder failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the Person asserting any such loss, claim, damage or liability in any case in which such delivery is required by the Securities Act.

Section 4.2    Indemnification by Holders. To the extent permitted by applicable law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration or qualification or compliance under applicable “blue sky” laws is being effected, indemnify, severally and not jointly, the Company, each of its directors, officers, partners, members, managers, shareholders, accountants, attorneys, agents and employees, each underwriter, if any, of the Company’s securities covered by such a registration, each Person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other Holder and each of such other Holder’s officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and employees and each Person controlling such Holder or any of the foregoing within the meaning of Section 15 of the Securities Act (collectively, the “Holder Indemnified Parties”), against all expenses, claims, losses, damages, costs (including costs of preparation and reasonable attorney’s fees and any legal or other fees or expenses actually incurred by such party in connection with any investigation or proceeding), judgments, fines, penalties, charges, amounts paid in settlement and other and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto incident to any such registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by such Holder of, or any rule or regulation promulgated under, the Securities Act, Exchange Act or state securities law applicable to such Holder, and will reimburse each of the Holder Indemnified Parties for any reasonable legal or any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and stated to be specifically for use therein, provided, however, that in no event shall any indemnity under this Section 4.2 payable by a Holder exceed the amount by which the net proceeds actually received by such Holder from the sale of Registrable Securities included in such registration exceeds the amount of any other losses, expenses, settlements, damages, claims and liabilities that such Holder has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. The indemnity agreement contained in this Section 4.2 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the prior written consent of the applicable Holder (which consent shall not be unreasonably withheld or delayed), nor shall the Holder be liable for any such loss, claim, damage, liability or action where such untrue statement or alleged untrue statement or omission or alleged omission was corrected in a final or amended prospectus, and the Company or the underwriters failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the Person asserting any such loss, claim, damage or liability in any case in which such delivery is required by the Securities Act

11

Section 4.3    Notification. Each party entitled to indemnification under this Article IV (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld or delayed), and the Indemnified Party may participate in such defense at such party’s expense; provided, further, however, that an Indemnified Party (together with all other Indemnified Parties) shall have the right to retain one (1) separate counsel, with the reasonable fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to conflicting interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall relieve the Indemnifying Party of its obligations under this Article IV, only to the extent that, the failure to give such notice is materially prejudicial or harmful to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the prior written consent of each Indemnified Party (which consent shall not be unreasonably withheld or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. The indemnity agreements contained in this Article IV shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The indemnification set forth in this Article IV shall be in addition to any other indemnification rights or agreements that an Indemnified Party may have.

Section 4.4    Contribution. If the indemnification provided for in this Article IV is held by a court of competent jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any claim, loss, damage, liability or action referred to therein, then, subject to the limitations contained in Article IV, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such claim, loss, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnified Party on the other in connection with the actions that resulted in such claims, loss, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact related to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were based solely upon the number of entities from whom contribution was requested or by any other method of allocation which does not take account of the equitable

12

considerations referred to above in this Section 4.4. In no event shall any Holder’s contribution obligation under this Section 4.4 exceed the amount by which the net proceeds actually received by such Holder from the sale of Registrable Securities included in such registration exceeds the amount of any other losses, expenses, settlements, damages, claims and liabilities that such Holder has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. No Person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.
