WHEREAS, the Company desires to grant to Warrantholder, in consideration for, among other things, the financial accommodations provided for in the Loan Agreement, the right to purchase shares of its Class A Common Stock (as defined below) pursuant to this Warrant Agreement (this “Warrant”);

“Act” means the Securities Act of 1933, as amended.

“Affiliate” means, with respect to any person, any other person directly or indirectly controlling, controlled by or under common control with such first person.

“Board” means the board of directors of the Company.

“Business Day” means any day, except Saturday, Sunday or legal holiday, on which banking institutions in the city of Los Angeles are authorized or obligated by law or executive order to close.

“Form Warrant” means a warrant in the form set forth in Exhibit E of the Loan Agreement.

“Purchase Price” means, with respect to any exercise of this Warrant, an amount equal to the Exercise Price as of the Exercise Date for such exercise multiplied by the number of Warrant Shares requested to be exercised under this Warrant pursuant to such exercise.

“Warrant Shares” means the shares of Class A Common Stock issuable upon exercise hereof.

Section 2. Term of the Agreement. Except as otherwise provided for herein, the term of this Warrant and the right to purchase Warrant Shares as granted under this Warrant shall commence on the Effective Date and shall be exercisable, in whole or in part, at any time, or from time to time, for a period ending at 5:00 p.m., California time, on the date that is seven (7) years after the Effective Date or, if such day is not a Business Day, on the next preceding Business Day (such date or next preceding Business Day, as applicable, the “Expiration Date”).

Section 3. Exercise of the Purchase Rights.

(a) Exercise. The purchase rights set forth in this Warrant are exercisable by Warrantholder, in whole or in part, at any time, or from time to time, prior to 5:00 p.m., California Time, on the Expiration Date, by tendering to the Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly completed and executed. The date on which such Notice of Exercise is so tendered is herein referred to as the “Exercise Date” for such exercise. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance with the terms set forth below, and in no event later than three (3) days thereafter, the Company shall issue to Warrantholder a certificate for the number of Warrant Shares purchased and shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain subject to future purchases, if any.

The Purchase Price may be paid at Warrantholder’s election either (i) by cash or check, or (ii) by surrender of this Warrant for Warrant Shares to be exercised under this Warrant, after which the Company shall, if the remaining number of shares purchasable hereunder (assuming no Net Issuance) immediately after the relevant exercise, as determined below, is greater than zero, execute and deliver, to Warrantholder, an amended Agreement covering such remaining number of shares (“Net Issuance”). If Warrantholder elects the Net Issuance method, the Company will issue Warrant Shares in accordance with the following formula:



Where:	X =	the number of Warrant Shares to be issued to Warrantholder.

	Y =	the number of Warrant Shares requested to be exercised under this Warrant (including the number of shares to be cancelled in payment of the Purchase Price).

	A =	the fair market value of one (1) share of Class A Common Stock on the Exercise Date.

	B =	the Exercise Price per share for such Warrant Shares.

For purposes of the above calculation, the fair market value of the Class A Common Stock shall mean with respect to each share of Class A Common Stock:

(i) if the Class A Common Stock is traded on the New York Stock Exchange, the American Stock Exchange, any exchange operated by the NASDAQ Stock Market, LLC or any other securities exchange, the fair market value shall be deemed to be the average of the closing prices per share over the five (5) trading day period ending on, and including, the Exercise Date; or

(ii) if at any time the Class A Common Stock is not listed on any securities exchange, the fair market value shall be the price per share which the Company could obtain from a willing buyer (not a current employee or Affiliate) for Class A Common Stock, in an arms’ length transaction, sold by the Company from authorized but unissued shares, as determined in good faith by the Board.

Upon partial exercise by either cash or Net Issuance, the Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder (assuming no Net Issuance). All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof.

(b) Exercise Prior to Expiration. To the extent this Warrant is not, as of the Expiration Date, previously exercised as to all the Warrant Shares subject hereto, and if the fair market value per share of Class A Common Stock on the Expiration Date is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised, on a Net Issuance basis, pursuant to Section 3(a) (even if not surrendered) on such Expiration Date. For purposes of such automatic exercise, the fair market value per share of Class A Common Stock upon such expiration shall be determined pursuant to Section 3(a). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify Warrantholder of the number of Warrant Shares, if any, Warrantholder is to receive by reason of such automatic exercise.

(c) Legend. Each certificate for the Warrant Shares purchased upon exercise of this Warrant shall bear the restrictive legend set forth on the first page of this Warrant. Such legend shall be removed and the Company shall, or shall instruct its transfer agent to, issue a certificate without such legend or any other legend to the holder of such shares (i) if such shares are sold or transferred pursuant to an effective registration statement under the Act covering the resale of such shares by the holder thereof, (ii) if such shares are sold or transferred pursuant to Rule 144 under the Act, (iii) if, upon advice of counsel to the Company, such shares are eligible for resale without any restrictions under Rule 144 under the Act, or (iv) upon the request of such holder if such request is accompanied (at such holder’s expense) by either (x) a written opinion of counsel reasonably satisfactory to the Company that registration is not required under the Act or any applicable state securities laws for the resale of the Warrant Shares purchased upon exercise of this Warrant or (y) a certification by such holder, in customary form, that conditions to the resale of such shares pursuant to Rule 144(b) (or any successor thereto) have been satisfied (it being understood that in no event shall such holder be required to certify as to the satisfaction of the conditions set forth in paragraph (c) or (i) of Rule 144 (or any successor thereto). The removal of such restrictive

legend from any certificates representing the Warrant Shares purchased upon exercise of this Warrant is predicated upon the Company’s reliance that the holder of such shares would sell, transfer, assign, pledge, hypothecate or otherwise dispose of such shares pursuant to either the registration requirements of the Act, including any applicable prospectus delivery requirements, or an exemption therefrom, or in a transaction not subject thereto, and that if such shares are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

Section 4. Reservation of Shares. During the term of this Warrant, the Company will at all times have authorized and reserved a sufficient number of shares of Class A Common Stock to provide for the exercise of the rights to purchase Warrant Shares as provided for herein, assuming this Warrant were exercised in full and not on a Net Issuance basis.

Section 5. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the fair market value per share of Class A Common Stock on the Exercise Date for such exercise.

Section 6. No Rights as Shareholder/Stockholder. This Agreement does not entitle Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to the exercise of this Warrant.

Section 7. Warrantholder Registry. The Company shall maintain a registry showing the name and address of the registered holder of this Warrant. Warrantholder’s initial address, for purposes of such registry, is set forth below Warrantholder’s signature on this Warrant. Warrantholder may change such address by giving written notice of such changed address to the Company.

Section 8. Adjustment Rights. The Exercise Price and the number of Warrant Shares purchasable hereunder are subject to adjustment, as follows:

(a) Class A Common Stock Change Event. If at any time there shall occur any transaction (each, a “Class A Common Stock Change Event”) (i) that is either (w) a recapitalization, reclassification or change of the Class A Common Stock (other than changes resulting from a subdivision or combination or changes in par value, including from par value to no par value or from no par value to par value); (x) any consolidation, merger or combination involving the Company; (y) any sale, lease or other transfer to a third party of substantially all of the consolidated assets of the Company and its subsidiaries, taken as a whole; or (z) any statutory share exchange; and (ii) as a result of such transaction, the Class A Common Stock would be converted into, or exchanged for, or would constitute solely the right to receive, stock, other securities or other property or assets (including cash or any combination thereof) (such stock, securities, property, assets or cash, the “Reference Property,” and the amount of Reference Property that a holder of one (1) share of Class A Common Stock would be entitled to receive on account of such transaction (without regard to any arrangement pursuant to which fractional units of property will not be delivered), a “Reference Property Unit”), then the Company or such successor or purchasing person, as the case may be, shall, as a condition precedent to such Class A Common Stock Change Event (and, in the event such successor or purchasing person is not the Company, the Company shall cause such successor or purchasing Person to) execute and deliver to Warrantholder an amended Warrant providing that, from and after the effective time of such Class A Common Stock Change Event, the consideration due upon exercise of this Warrant shall be determined in the same manner as if each reference to any number of shares of Class A Common Stock in this Warrant were instead a reference to the same number of Reference Property Units. For the avoidance of doubt, from and after such effective time, the fair market value of a Reference Property Unit shall be determined (x) to the extent any component thereof consists of securities, on the same basis as that set forth in the penultimate paragraph

of Section 3(a) and (y) to the extent any component thereof does not consist of securities, on the basis of the fair market value thereof (determined in good faith by the Board or the board of directors or similar governing body of the Company’s successor). If a Class A Common Stock Change Event causes the Class A Common Stock to be converted into, or exchanged for, or to constitute solely the right to receive, more than a single type of consideration (determined based in part upon any form of stockholder election), then the amount and kind of Reference Property used to determine the composition of the Reference Property Unit shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Class A Common Stock that affirmatively make such an election. If such successor or purchasing person is not the Company, then such amended Warrant shall provide for the assumption, by such successor or purchasing person, of the Company’s obligations with respect hereto. If, pursuant to such Class A Common Stock Change Event, the Reference Property includes shares of stock or other securities and property of a person other than the successor or purchasing person, as the case may be, in such Class A Common Stock Change Event, then such amended Warrant shall also be executed by such other person. In connection with a Class A Common Stock Change Event, Warrantholder may exercise this Warrant, in whole or in part, with the Exercise Date being deemed to be the effective date of such Class A Common Stock Change Event, without the need for the relevant Notice of Exercise to specify such effective date, provided such Notice of Exercise is tendered to the Company no later than three days before the effective date of such Class A Common Stock Change Event.

(b) Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide the Class A Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, and the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) shall be proportionately increased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased, and the number of Warrant Shares issuable upon the exercise of this Warrant shall be proportionately decreased.

(i) pay a dividend with respect to the Class A Common Stock payable in Class A Common Stock, then (x) the Exercise Price shall be adjusted, from and after the ex date for such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such ex date by a fraction (A) the numerator of which shall be the total number of shares of Class A Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Class A Common Stock outstanding immediately after such dividend or distribution; and (y) the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) shall be adjusted, from and after such ex date, to that number of shares determined by multiplying the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) immediately prior to such ex date by the reciprocal of the fraction referred to in clause (x) above; or

(ii) make any other distribution with respect to Class A Common Stock, except any distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision shall be made by the Company such that Warrantholder shall receive upon each subsequent exercise of this Warrant, the same kind and amount of property it would have received in such distribution had Warrantholder held, on the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution, a number of shares of Class A Common Stock equal to the number of Warrant Shares issuable upon such exercise.

(d) Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon its stock, whether in stock, cash, property or other securities; (ii) the Company shall offer for subscription pro rata to the holders of any class of common stock or other convertible stock any additional shares of stock of any class or other rights; (iii) there shall occur any Class A Common Stock Change Event; (iv) the Company shall sell, lease, license or otherwise transfer all or substantially all of its assets; or (v) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to Warrantholder: (A) at least thirty (30) days’ prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution, subscription rights (specifying the date on which the holders of common stock shall be entitled thereto) or for determining rights to vote in respect of such Class A Common Stock Change Event, dissolution, liquidation or winding up; and (B) in the case of any such Class A Common Stock Change Event, dissolution, liquidation or winding up, at least thirty (30) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of common stock shall be entitled to exchange their common stock for securities or other property deliverable upon such Class A Common Stock Change Event, dissolution, liquidation or winding up).

Each such written notice shall set forth, in reasonable detail, (i) the event requiring the notice, and (ii) if any adjustment is required to be made, (A) the amount of such adjustment, (B) the method by which such adjustment was calculated, (C) the adjusted Exercise Price (if the Exercise Price has been adjusted), and (D) the total number of Warrant Shares subject to purchase hereunder (assuming no Net Issuance) after giving effect to such adjustment, and shall be given by first class mail, postage prepaid, or by reputable overnight courier with all charges prepaid, addressed to Warrantholder at the address for Warrantholder set forth in the registry referred to in Section 7.

(e) Timely Notice. Failure to timely provide such notice required by subsection (d) above shall entitle Warrantholder to retain the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Warrantholder. For purposes of this subsection (f), and notwithstanding anything to the contrary in Section 12(f), the notice period shall begin on the date Warrantholder actually receives a written notice containing all the information required to be provided in such subsection (d).

Section 9. Representations, Warranties and Covenants of the Company.

(a) Reservation of Warrant Shares. The Warrant Shares issuable upon exercise of Warrantholder’s rights (assuming no Net Issuance) have been duly and validly reserved and, when issued in accordance with the provisions of this Warrant, will be validly issued, fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; provided, that the Warrant Shares issuable pursuant to this Warrant may be subject to restrictions on transfer under state and/or federal securities laws. The Company has made available to Warrantholder true, correct and complete copies of its Charter and Bylaws. The issuance of certificates for Warrant Shares upon exercise of this Warrant shall be made without charge to Warrantholder for any issuance tax in respect thereof, or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares; provided, that the Company shall not be required to pay any tax which may be payable in respect of any transfer and the issuance and delivery of any certificate in a name other than that of Warrantholder.

(b) Due Authority. The execution and delivery by the Company of this Warrant and the performance of all obligations of the Company hereunder, including the issuance to Warrantholder of the Warrant Shares issuable hereunder, have been duly authorized by all necessary corporate action on the part of the Company. This Agreement: (i) does not violate the Company’s Charter or Bylaws; (ii) does not contravene any law or governmental rule, regulation or order applicable to the Company; and (iii) does not and will not contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound. This Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms.

(c) Consents and Approvals. No consent or approval of, giving of notice to, registration with, or taking of any other action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, delivery and performance by the Company of its obligations under this Warrant, except for the filing of notices pursuant to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the time required thereby.

(d) Issued Securities. All issued and outstanding Class A Common Stock or other securities of the Company have been duly authorized and validly issued and are fully paid and nonassessable. All outstanding Class A Common Stock or other securities of the Company were issued in full compliance with all federal and state securities laws.

(e) Exempt Transaction. Subject to the accuracy of Warrantholder’s representations in Section 10, the issuance of the Warrant Shares upon exercise of this Warrant will constitute a transaction exempt from (i) the registration requirements of Section 5 of the Act, in reliance upon Section 4(2) thereof, and (ii) the qualification requirements of the applicable state securities laws.

(f) Compliance with Rule 144. If Warrantholder proposes to sell Warrant Shares issuable upon the exercise of this Warrant in compliance with Rule 144 promulgated by the Securities and Exchange Commission (the “SEC”), then, upon Warrantholder’s written request to the Company, the Company shall furnish to Warrantholder, within three Business Days after receipt of such request, a written statement confirming the Company’s compliance with the requirements of paragraphs (c) and (i) of such Rule, as such Rule may be amended from time to time. Until such time as this Warrant and the Warrant Shares issued hereunder have been sold pursuant to an effective registration statement under the Act or such time as the requirements of paragraph (c) of Rule 144, as such Rule may be amended from time to time, no longer apply to this Warrant or to such shares, the Company covenants to timely file all reports required to be filed by the Company under the Securities Exchange Act of 1934, as amended (the “1934 Act”), in such a manner so as to comply with paragraph (c) of Rule 144, as such Rule may be amended from time to time.

(g) Denomination Exchanges. Warrantholder shall have the right to request the Company to cause any portion of this Warrant to be represented by one or more separate warrants (each, a “Separate Warrant”), each in the form of a Form Warrant, and the Company hereby covenants that, upon each such request, the Company shall (x) execute and deliver, to Warrantholder, an amended Warrant, which shall reflect the removal of such portion of such portion of this Warrant; and (y) execute and deliver, to Warrantholder, one or more Separate Warrants, each in the form of the Form Warrant, having an aggregate number of underlying Warrant Shares (assuming no Net Issuance), and having a per share Exercise Price, equal to the number of underlying Warrant Shares (assuming no Net Issuance) and the Exercise price, respectively, of such portion of this Warrant.

Section 10. Representations and Covenants of Warrantholder. This Agreement has been entered into by the Company in reliance upon the following representations and covenants of Warrantholder:

(a) Investment Purpose. The right to acquire Warrant Shares upon exercise of Warrantholder’s rights contained herein will be acquired for investment and not with a view to the sale or distribution of any part thereof, and Warrantholder has no present intention of selling or engaging in any public distribution of the same, in each case except pursuant to a registration or exemption.

(b) Private Issue. Warrantholder understands (i) that the Warrant Shares issuable upon exercise of this Warrant is not registered under the Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Warrant will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s reliance on such exemption is predicated in part on the representations set forth in this Section 10.

(c) Financial Risk. Warrantholder has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of its investment.

(d) Risk of No Registration. Warrantholder understands that if the Company does not have any class of its securities registered pursuant to Section 12 of the 1934 Act, or file reports pursuant to Section 15(d) of the 1934 Act, or if a registration statement covering this Warrant or the underlying Warrant Shares under the Act is not in effect when it desires to sell (i) the rights to purchase Warrant Shares pursuant to this Warrant or (ii) the Warrant Shares issuable upon exercise of the right to purchase, it may be required to hold such securities for an indefinite period. Warrantholder also understands that any sale of (A) its rights hereunder to purchase Warrant Shares or (B) Warrant Shares issued or issuable hereunder which might be made by it in reliance upon Rule 144 under the Act may be made only in accordance with the terms and conditions of that Rule.

(e) Accredited Investor. Warrantholder is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Act.

(f) No Short Sales. Prior to the Effective Date, Warrantholder has not engaged in any “short sales” of the Class A Common Stock, which short sales have not been covered before such Effective Date. At no time when Warrantholder holds (or has a beneficial interest in) any Warrant Shares issued or issuable pursuant to this Warrant shall Warrantholder engage in “short sales” of the Class A Common Stock. The term “short sale” shall mean any sale of a security which the seller does not own or any sale which is consummated by the delivery of a security borrowed by, or for the account of, the seller.

Section 11. Transfers. Subject to compliance with applicable federal and state securities laws, this Warrant and all rights hereunder are transferable, in whole or in part, without charge to the holder hereof (except for transfer taxes) upon surrender of this Warrant properly endorsed. Each taker and holder of this Warrant, by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank, shall be deemed negotiable, and that the holder hereof, when this Warrant shall have been so endorsed and its transfer recorded on the Company’s books, shall be treated by the Company and all other persons dealing with this Warrant as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Warrant. The transfer of this Warrant shall be recorded on the books of the Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the “Transfer Notice”), at its principal offices and the payment to the Company of all transfer taxes and other governmental charges imposed on such transfer, in each case that are not to be paid by the Company pursuant hereto. Until the Company receives such Transfer Notice, the Company may treat the registered owner hereof as the owner for all purposes.

Section 12. Miscellaneous.

(a) Effective Date. The provisions of this Warrant shall be construed and shall be given effect in all respects as if it had been executed and delivered by the Company on the date hereof. This Agreement shall be binding upon any successors or assigns of the Company.

(b) Remedies. In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any such default, and/or an action for specific performance for any default where the non-defaulting party will not have an adequate remedy at law and where damages will not be readily ascertainable. Each party hereto expressly agrees that it shall not oppose an application by the non-defaulting party or any other person entitled to the benefit of this Warrant requiring specific performance of any or all provisions hereof or enjoining a party from continuing to commit any such breach of this Warrant. The parties hereto hereby agree that the terms of this Warrant shall be specifically enforceable by either party hereto.

(c) No Impairment of Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of Warrantholder against impairment.

(d) Attorney’s Fees.

(f) Notices. Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service of process or other communication that is required, contemplated, or permitted under this Warrant or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given, delivered, and received upon the earlier of: (i) the day of transmission by facsimile or hand delivery if transmission or delivery occurs on a Business Day at or before 5:00 pm in the time zone of the recipient, or, if transmission or delivery occurs on a non-Business Day or after such time, the first Business Day thereafter, or the first Business Day after deposit with an overnight express service or overnight mail delivery service; or (ii) the third calendar day after deposit in the United States mails, with proper first class postage prepaid, and shall be addressed to the party to be notified as follows:

(n) Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such Claims, including Claims that involve persons other than the Company and Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind, arising out of this Warrant.

(o) Arbitration. If the Mutual Waiver of Jury Trial set forth in Section 12(n) is ineffective or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired New York state judge or a retired Federal court judge. Such proceeding shall be conducted in New York, New York, with New York rules of evidence and discovery applicable to such arbitration. The decision of the arbitrator shall be binding on the parties, and shall be final and nonappealable to the maximum extent permitted by law. Any judgment rendered by the arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of such court.

(p) Prearbitration Relief. In the event Claims are to be resolved by arbitration, either party may seek from a court of competent jurisdiction identified in Section 12(m), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by binding arbitration.

(q) Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.

(r) Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to a party hereto by reason of the other party’s failure to perform any of the obligations under this Warrant and agree that the terms of this Warrant shall be specifically enforceable by either party hereto. If a party hereto institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that such party has an adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
