(d)For purposes of determining, with respect to any vesting condition set forth in Sections 3(a) or 3(b) above (each a “Milestone”, and any Milestone that has not been satisfied as of any specific date, an “Unsatisfied Milestone”), at which point in time CCCM pays Company and its Affiliates, if (1) the Company delivers any products or services to CCCM and (2) CCCM returns any such products to the Company, or otherwise contest such products or services, because they were defective or otherwise not in compliance with the Master Agreement, the Addendum or any other agreement, which for the avoidance of doubt shall be subject to any materiality thresholds, cure periods or other relevant terms which apply to defects and matters of non-compliance as set forth in such agreements, governing the relevant purchase, then, for purposes of this Warrant only, such return or contestation shall not affect the point in time at which such products or services shall be deemed to have been paid for by CCCM; provided, however, that this Section 3(d) shall not apply to Harmonic CableOS Software prior to General Availability. Notwithstanding anything herein to the contrary, to the extent, at any point in time, any Milestone is an Unsatisfied Milestone as a result, directly or indirectly, of the Company’s failure to perform any of its respective material obligations under, and in accordance with, the Master Agreement, the Addendum or any other agreement, which for the avoidance of doubt shall be subject to any materiality thresholds, cure periods or other relevant terms which apply to defects and matters of non-compliance as set forth in such agreements, governing the relevant purchase, including, without limitation, failure to timely invoice such products or services, then such Milestone(s) shall, assuming all other actions required to be taken by CCCM with respect to the vesting criteria associated with such Milestone is otherwise completed, be deemed to have been satisfied for all purposes hereunder, and the Holder’s rights hereunder shall vest and become exercisable with respect to the Warrant Shares set forth in such Milestone(s), at such time as such Milestone(s) would have been satisfied but for such failure by the Company to perform such obligations. For the avoidance of doubt, CCCM shall take no action to directly

cause the Company to fail to perform any of its material obligations under the Master Agreement, the Addendum or any other agreement.

(e)    To the extent any vesting trigger above remains unsatisfied at the end of the applicable time period (whether pursuant to satisfaction of the Primary Vesting Triggers or the Secondary Vesting Triggers or the acceleration of vesting pursuant to Section 3(c)), the Holder’s unvested right to exercise this Warrant with respect to the relevant Warrant Shares will expire at the end of such time period without notice to the Holder or any other action required to be taken by the Company and, only with respect to the Primary Vesting Triggers, will have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of expired Warrant Shares. The Holder and the Company shall maintain records showing the number of expired Warrant Shares. Nothing in this Section 3(d) shall affect the exercise of any vested portion of this Warrant, whether exercised pursuant a Notice of Exercise or deemed exercise pursuant to Section 10(b).

(f)    All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be, and all dollar amounts in this Section 3 shall be before applicable taxes.

(a)Exercise. The purchase rights represented by this Warrant may be exercised once vested at the election of the Holder, in whole or in part, in accordance with Section 2, by the tender to the Company at its principal office (or such other office or agency as the Company may designate) of a notice of exercise in the form of Exhibit A (the “Notice of Exercise”), duly completed and executed by or on behalf of the Holder, together with the surrender of this Warrant. The date on which a Notice of Exercise shall have taken place shall be referred to as its “Exercise Date”).

(b)Physical Delivery.

(c)Net Issue Exercise. The Holder may, in lieu of exercising this Warrant by Physical Delivery pursuant to Section 4(b), if the Fair Market Value of one Share is greater than the Exercise Price (at the date of calculation as set forth below), elect to receive (a “Net Issue Exercise”) a number of Shares equal to the value of this Warrant (or of any portion of this Warrant being canceled), as calculated below, by surrender of this Warrant at the principal office of the Company (or such other office or agency as the Company may designate) together with a properly completed and executed Notice of Exercise reflecting such election, in which event the Company shall issue to the Holder that number of Shares computed using the following formula:

Where:

(i)Definitions.

(1)For purposes of this Warrant, the “Fair Market Value” of a Share is defined as follows:

a)if a public market exists for the Company’s common stock at the time of such exercise, the Fair Market Value per Share shall be the weighted average trading price of the Company’s common stock for the ten (10) trading day period ending the trading day prior to the Exercise Date (without regard for pre-open and after hours trading outside of any regular trading session for any such trading day), calculated by multiplying the closing trading price quoted on the national securities exchange on which the common stock is listed (determined by reference to the screen entitled “HLIT <Equity> AQR” reported by Bloomberg L.P., or, if such screen is no longer available, as otherwise reported by Bloomberg L.P), as applicable, on each of the preceding 10 days by the trading volume on each such day and dividing that total by the total aggregate trading volume over the preceding 10-day period;

b)if the exercise is in connection with a Change of Control, then the Fair Market Value shall be: (i) the aggregate Fair Market Value of the consideration received or to be received in such Change of Control by the holders of the Common Stock of the Company (including for purposes of this clause (i), any consideration received or to be received by Holder in such Change of Control in respect of this Warrant) divided by (ii) the total number of Shares issued and outstanding on the date of such Change of Control (including for purposes of this clause (ii) the number of Warrant Shares in respect of which Holder has received or is to receive consideration in such Change of Control); and

c)if there is no active public market for the Shares, and the exercise is not in connection with a Change of Control, the Fair Market Value of a Share shall be the price that would be negotiated in an arm’s-length transaction for cash between a willing seller and a willing and able buyer, both having full knowledge of the relevant facts and neither of which is under any compulsion to complete the transaction, without regard for control premiums or minority or illiquidity discounts, as such price is determined in good faith by the Company’s Board of Directors (the “Board”), provided that (A) the Company shall give the Holder prompt written notice of any such determination, together with reasonable data and documentation to support such determination, and (B) if the Holder disputes the Board’s determination, it shall promptly notify the Company of such dispute, whereupon the Company shall engage a nationally recognized investment bank or other independent valuation firm reasonably acceptable to the Holder (an “Appraiser”) to determine such Fair Market Value, the cost of which Appraiser shall be borne by the Company (unless the Appraiser’s determination of the Fair Market Value is not greater than 105% percent or less than 95% percent of the Fair Market Value as determined by the Board, in which case the cost of the Appraiser

shall be borne by the Holder) and the determination of such Appraiser shall be final and binding on the Company and the Holder.

(2)For purposes of this Warrant, the “Fair Market Value” of an equity interest other than a Share is defined as follows:

a)if a public market exists for such equity interest at the time of such exercise, the Fair Market Value of each such equity interest shall be the weighted average trading price of such equity interest for the ten (10) trading day period ending the trading day prior to the Exercise Date (without regard for pre-open and after hours trading outside of any regular trading session for any such trading day), calculated by multiplying the closing trading price quoted on the national securities exchange on which the common stock is listed as reported by Bloomberg L.P, as applicable, on each of the preceding 10 days by the trading volume on each such day and dividing that total by the total aggregate trading volume over the preceding 10-day period; and

b)if there is no active public market for such equity interest, the Fair Market Value of such equity interest shall be the price that would be negotiated in an arm’s-length transaction for cash between a willing seller and a willing and able buyer, both having full knowledge of the relevant facts and neither of which is under any compulsion to complete the transaction, without regard for control premiums or minority or illiquidity discounts, as such price is determined in good faith by the Board, provided that (A) the Company shall give the Holder prompt written notice of any such determination, together with reasonable data and documentation to support such determination, and (B) if the Holder disputes the Board’s determination, it shall promptly notify the Company of such dispute, whereupon the Company shall engage an Appraiser to determine such Fair Market Value, the cost of which Appraiser shall be borne by the Company (unless the Appraiser’s determination of the Fair Market Value is not greater than 105% percent or less than 95% percent of the Fair Market Value as determined by the Board, in which case the cost of the Appraiser shall be borne by the Holder) and the determination of such Appraiser shall be final and binding on the Company and the Holder.

(3)For purposes of this Warrant, the “Fair Market Value” of an asset other than an equity interest shall be the price that would be negotiated in an arm’s-length transaction for cash between a willing seller and a willing and able buyer, both having full knowledge of the relevant facts and neither of which is under any compulsion to complete the transaction, without regard for control premiums or minority or illiquidity discounts, as such price is determined in good faith by the Board, provided that (A) the Company shall give the Holder prompt written notice of any such determination, together with reasonable data and documentation to support such determination, and (B) if the Holder disputes the Board’s determination, it shall promptly notify the Company of such dispute, whereupon the Company shall an Appraiser to determine such Fair Market Value, the cost of which Appraiser shall be borne by the Company (unless the Appraiser’s determination of the Fair Market Value is not greater than 105% percent or less than 95% percent of the Fair Market Value as determined by the Board, in which case the cost of the Appraiser shall be borne by the Holder) and the determination of such Appraiser shall be final and binding on the Company and the Holder.

(d)Stock Certificates. The rights under this Warrant shall be deemed to have been exercised and the Warrant Shares issuable upon such exercise shall be deemed to have been issued immediately prior to the close of business on the Exercise Date, and the person entitled to receive the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such Warrant Shares as of the close of business on the Exercise Date. As promptly as reasonably practicable on or after such date, but in any event within five (5) Business Days following the Exercise Date, the Company shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for that number of Shares issuable upon such exercise; provided, however, that if the Holder shall request book entry position evidencing that number of Shares issuable upon such exercise, the Company shall complete such book entry on the Exercise Date. In the event that the rights under this Warrant are exercised in part and

have not expired, the Company shall execute and deliver a new Warrant reflecting the number of Warrant Shares that remain subject to this Warrant.

(e)No Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon the exercise of the rights under this Warrant. In lieu of such fractional Share to which the Holder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.

(f)Conditional Exercise. The Holder may exercise this Warrant conditioned upon (and effective immediately prior to) the consummation of a Change of Control that would cause the expiration of this Warrant pursuant to Section 8 by so indicating in the notice of exercise.

5.    Replacement of the Warrant.

Any Holder of this Warrant (or of any portion of this Warrant) may change its address as shown on the Warrant Register by written notice to the Company requesting a change.

(b)    Warrant Agent. The Company may appoint an agent for the purpose of maintaining the Warrant Register referred to in Section 6(a), issuing the Warrant Shares or other securities then issuable upon the exercise of the rights under this Warrant, exchanging this Warrant, replacing this Warrant or conducting related activities.

(d)    Exchange of the Warrant upon a Transfer.

This Warrant (and the securities issuable upon exercise of the rights under this Warrant) must be surrendered to the Company or its warrant or transfer agent, as applicable, as a condition precedent to the sale, pledge, hypothecation or other transfer of any interest in any of the securities represented hereby.

(e)    Minimum Transfer This Warrant may not be transferred in part unless such transfer is to a transferee who, pursuant to such transfer, receives the right to purchase at least 250,000 Warrant Shares hereunder (as may be adjusted pursuant hereto prior to (or in connection with) the expiration of this Warrant as provided in Section 10).

(f)    Taxes and Expenses. The Company shall pay all of its expenses in connection with, and all issuance, transfer, stamp and other similar incidental taxes imposed by any taxing authority in the United States with respect to, the exercise of this Warrant or the issue or delivery of Warrant Shares or the payment of any cash settlement amount hereunder; provided, however, that, in no event shall the Company be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or is not payable.

7.    Restrictions on Transfer of the Warrant and Warrant Shares; Compliance with Securities Laws. By acceptance of this Warrant, the Holder agrees that its rights pursuant to this Warrant are subject to the following:

(a)    Restrictions on Transfers. This Warrant may not be directly transferred or assigned in whole or in part without the Company’s prior written consent, other than to: (x) any Affiliate of the Holder, so long as such Affiliate consents in writing to be bound by the terms and conditions of this Warrant, (y) a successor in interest of the Holder or as part of a corporate reorganization, consolidation or merger; or (z) in connection with a Strategic Transaction (as defined below), and any attempt by Holder to directly transfer or assign any rights, duties or obligations that arise under this Warrant without such permission shall be void. As used herein, a “Strategic Transaction” means any transaction or series of related transactions where the Fair Market Value of the unvested portion of this Warrant sold, assigned, transferred, pledged or disposed of or in connection with such transaction(s) constitutes less than 10% of the aggregate value of such transactions. For the avoidance of doubt, nothing in this Warrant shall prohibit any indirect transfer of this Warrant or any interest herein. Any transfer of this Warrant or the Warrant Shares (the “Securities”) must be in compliance with all applicable federal and state securities laws. The Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Securities, or any beneficial interest therein, unless and until:

(i)there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement, or

(ii)(A) such Holder shall have given prior written notice to the Company of such Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, (B) the transferee shall have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Securities are being acquired (i) solely for the transferee’s own account and not as a nominee for any other party, (ii) for investment and (iii) not with a view toward distribution or resale, and shall have confirmed such other matters related thereto as may be reasonably requested by the Company, and (C) such Holder shall have furnished the Company, at the Holder’s expense, with (i) an opinion of counsel, reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Securities under the Securities Act or (ii) a “no action” letter from the Securities and Exchange Commission to the effect that the transfer of such Securities without registration will not result in a recommendation by the staff of the Securities and Exchange Commission that action be taken with respect thereto, whereupon such Holder shall be entitled to transfer such Securities in accordance with the terms of the notice delivered by the Holder to the Company; and

other than in the case of open market transactions, the transferee thereof has agreed in writing for the benefit of the Company to take and hold such Securities subject to, and to be bound by, the terms and conditions set forth in this Warrant to the same extent as if the transferee were the original Holder hereunder.

(b)    Investment Representation Statement. Unless the rights under this Warrant are exercised pursuant to an effective registration statement under the Securities Act that includes the Shares with respect to which the Warrant was exercised, it shall be a condition to any exercise of the rights under this Warrant that the Holder shall have confirmed to the satisfaction of the Company in writing, substantially in the form of Exhibit A-1, that the Shares so purchased are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the Holder shall have confirmed such other matters related thereto as may be reasonably requested by the Company.

(c)    Legends. The Securities shall (unless otherwise permitted by the provisions of this Warrant) be stamped or imprinted with legends substantially similar to the following (in addition to any legend required by state securities laws):

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS IN ACCORDANCE WITH APPLICABLE REGISTRATION REQUIREMENTS OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THIS CERTIFICATE MUST BE SURRENDED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF ANY INTEREST IN ANY OF THE SECURITIES REPRESNTED HEREBY.

(d)    Instructions Regarding Transfer Restrictions. The Holder consents to the Company making a notation on its records and giving instructions to any transfer agent in order to implement the restrictions on transfer established in this Section 7.

(e)    Removal of Legend. The legend referring to federal and state securities laws identified in Section 7(c) stamped on a certificate evidencing the Shares and the stock transfer instructions and record notations with respect to such securities shall be removed and the Company shall issue a certificate without such legend to the holder of such securities if (i) such securities are registered under the Securities Act, or (ii) such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a sale or transfer of such securities may be made without registration or qualification.

(f)    Registration Rights. Contemporaneously with the execution of this Warrant, the Holder and the Company will enter into a Registration Rights Agreement, dated as of the date hereof (the “Registration Rights Agreement”). The Warrant Shares issuable upon exercise of this Warrant shall be Registrable Securities (as defined in the Registration Rights Agreement).

8.    Adjustments. Subject to the expiration of this Warrant pursuant to Section 10, the number and kind of shares purchasable hereunder and the Exercise Price therefor are subject to adjustment from time to time, as follows:

(a)    Merger or Reorganization. If at any time there shall be any reorganization, recapitalization, merger or consolidation (a “Reorganization”) involving the Company (other than as otherwise provided for herein or as would cause the expiration of this Warrant under Section 10) in which shares of the Company’s stock are converted into or exchanged for securities, cash or other property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, the kind and amount of securities, cash or other property of the successor corporation resulting from such Reorganization (the “Alternate Consideration”), equivalent in value to that which a holder of the Warrant Shares deliverable upon exercise of this Warrant would have been entitled in such Reorganization if the right to purchase the Warrant Shares hereunder had been exercised immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board of Directors of the successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this Warrant.

(b)    Reclassification of Shares. If the securities issuable upon exercise of this Warrant are changed into the same or a different number of securities of any other class or classes by reclassification, capital reorganization or otherwise (other than as otherwise provided for herein) (a “Reclassification”), then, in any such event, in lieu of the number of Warrant Shares which the Holder would otherwise have been entitled to receive, the Holder shall have the right thereafter to exercise this Warrant for a number of shares of such other class or classes of stock that a holder of the number of securities deliverable upon exercise of this Warrant immediately before that change would have been entitled to receive in such Reclassification, all subject to further adjustment as provided herein with respect to such other shares.

(c)    Subdivisions and Combinations. In the event that the outstanding Shares are subdivided (by stock split, by payment of a stock dividend or otherwise) into a greater number of shares of such securities, the number of Warrant Shares issuable upon exercise of the rights under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the outstanding Shares are combined (by reclassification or otherwise) into a lesser number of shares of such securities, the number of Warrant Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately decreased, and the Exercise Price shall be proportionately increased.

(d)    Other Dividends and Distributions. If the Company shall, at any time or from time to time after the Issue Date, make or declare, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or any other distribution payable in securities of the Company (other than a dividend or distribution of Shares in respect of outstanding Shares), cash, rights or other property, then, and in each such event, provision shall be made so that the Holder shall receive upon exercise of the Warrant, in addition to the number of Warrant Shares receivable thereupon, the kind and amount of securities of the Company, cash, rights or other property which the Holder would have been entitled to receive had the Warrant been exercised in full into Warrant Shares on the date of such event and had the Holder thereafter, during the period from the date of such event to and including the Exercise Date, retained such securities, cash or other property receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this Section 8 with respect to the rights of the Holder; provided, that no such provision shall be made if the Holder receives, simultaneously with the distribution to the holders of Common Stock, a dividend or other distribution of such securities, cash or other property in an amount equal to the amount of such securities, cash or other property as the Holder would have received if the Warrant had been exercised in full into Warrant Shares on the date of such event.

(e)    Notice of Adjustments. Upon any adjustment to the Warrant, including any adjustment pursuant to this Section 8, the Company shall give notice thereof to the Holder, which notice shall state the event giving rise to the adjustment, the Exercise Price as adjusted and the number of securities or other property purchasable upon the exercise of the rights under this Warrant, setting forth in reasonable detail the method of calculation of each. The Company shall, upon the written request of any Holder, furnish or cause to be furnished to such Holder a certificate setting forth (i) such adjustments, (ii) the Exercise Price at the time in effect and (iii) the number of securities and the amount, if any, of other property that at the time would be received upon exercise of this Warrant.

(f)    Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action that would require an adjustment pursuant to this Section 8, the Company shall take any and all actions that may be necessary, including, without limitation, obtaining regulatory, the NASDAQ Stock Market or other applicable national securities exchange or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and non-assessable all Warrant Shares and, as applicable, all Alternate Consideration that the Holder is entitled to receive upon exercise of this Warrant.

9.    Notification of Certain Events. Prior to the expiration of this Warrant pursuant to Section 10, in the event that the Company shall authorize:

(a)    the issuance of any dividend or other distribution on the capital stock of the Company or any reduction in the number of outstanding Shares or any other company security then issuable upon exercise of this Warrant, whether as a result of repurchases by the Company or otherwise, (in each case, other than (i) dividends or distributions provided for in Section 8(c), (ii) repurchases of Shares issued to or held by employees, officers, directors or consultants of the Company or its subsidiaries upon termination of their employment or services pursuant to agreements providing for the right of said repurchase, (iii) repurchases of Shares issued to or held by employees, officers, directors or consultants of the Company or its subsidiaries pursuant to rights of first refusal or first offer contained in agreements providing for such rights), whether in cash, property, stock or other securities, (iv) repurchases of Shares pursuant to the Company’s stock repurchase program as authorized from time to time by the Board, or (v) Shares used to pay taxes in accordance with the Company’s equity incentive programs approved by the Board;

The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by the consent of the Holder of this Warrant.

10.    Expiration of the Warrant.

11.    No Rights as a Stockholder. Nothing contained herein shall entitle the Holder to any rights as a stockholder of the Company for any purpose nor shall anything contained herein be construed to confer upon the Holder, as such, any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or any other rights of a stockholder of the Company until the rights under the Warrant shall have been exercised and the Warrant Shares purchasable upon exercise of the rights hereunder shall have become deliverable as provided herein.

COMPANY:        HARMONIC INC.

DATE:            ______________________________________________                    

In connection with the purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to, and agrees with, the Company as follows:

1.No Registration. The Investor understands that the Securities have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Investor’s representations as expressed herein or otherwise made pursuant hereto.

2.Investment Intent. The Investor is acquiring the Securities for investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof. The Investor has no present intention of selling, granting any participation in, or otherwise distributing the Securities, nor does it have any contract, undertaking, agreement or arrangement for the same.

3.Investment Experience. The Investor has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company, and has such knowledge and experience in financial or business matters so that it is capable of evaluating the merits and risks of its investment in the Company and protecting its own interests.

4.Speculative Nature of Investment. The Investor understands and acknowledges that its investment in the Company is highly speculative and involves substantial risks. The Investor can bear the economic risk of its investment and is able, without impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

5.Access to Data. The Investor has had an opportunity to ask questions of officers of the Company, which questions were answered to its satisfaction. The Investor believes that it has received all the information that it considers necessary or appropriate for deciding whether to acquire the Securities. The Investor understands that any such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the Company’s business and prospects, but were not necessarily a thorough or exhaustive description. The Investor acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections included in such business plans or otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results.

6.Accredited Investor. The Investor is an “accredited investor” within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission and agrees to submit to the Company such further assurances of such status as may be reasonably requested by the Company. The Investor has furnished or made available any and all information requested by the Company or otherwise necessary to satisfy any applicable verification requirements as to “accredited investor” status. Any such information is true, correct, timely and complete.

7.Residency. The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business) is correctly set forth on the signature page hereto.

8.Restrictions on Resales. The Investor acknowledges that the Securities must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. The Investor is aware of the provisions of Rule 144 promulgated under the Securities Act, which permit resale of shares purchased in a private placement subject to the satisfaction of certain conditions, which may include, among other things, the availability of certain current public information about the Company; the resale occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being sold during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s transaction,” a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder); and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time the Investor wishes to sell the Securities and that, in such event, the Investor may be precluded from selling the Securities under Rule 144 even if the other applicable requirements of Rule 144 have been satisfied. The Investor understands and acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. The Investor understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for those offers or sales and that those persons and the brokers who participate in the transactions do so at their own risk.

9.Brokers and Finders. The Investor has not engaged any brokers, finders or agents in connection with the Securities, and the Company has not incurred nor will incur, directly or indirectly, as a result of any action taken by the Investor, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with the Securities.

10.Legal Counsel. The Investor has had the opportunity to review the Warrant, the exhibits and schedules attached thereto and the transactions contemplated by the Warrant with its own legal counsel. The Investor is not relying on any statements or representations of the Company or its agents for legal advice with respect to this investment or the transactions contemplated by the Warrant.

11.Tax Advisors.
