 SECTION 3. EXERCISE OF THE PURCHASE RIGHTS. 

(a)        Exercise. The purchase rights set forth in this Warrant are exercisable by the
Warrantholder, in whole or in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, 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. 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
ten (10) days (three (3) days, if the Company’s securities are then publicly traded) thereafter, the Company shall issue to the Warrantholder a certificate for the number of shares of Preferred Stock 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 the Warrantholder’s election either (i) by cash or check, or (ii) by surrender of all or a
portion of the Warrant for shares of Preferred Stock to be exercised under this Warrant and, if applicable, a new warrant of like tenor representing the remaining number of shares purchasable hereunder, as determined below (“Net
Issuance”). If the Warrantholder elects the Net Issuance method, the Company will issue Preferred Stock in accordance with the following formula: 

X = Y(A-B) 

      A 

Where:        X = the number of shares of Preferred Stock to be issued to the Warrantholder. 

Y = the number of shares of Preferred Stock 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 Preferred Stock at
the time of issuance of such shares of Preferred Stock. 
 B=    the Exercise Price. 

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

(i)        if the exercise is in connection with an Initial Public Offering, and if
the Company’s Registration Statement relating to such Initial Public Offering has been declared effective by the SEC, then the fair market value per share shaft be the product of (x) the initial “Price to Public” of the Common
Stock specified in the final prospectus with respect to the offering and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise; 

(ii)        if the exercise is after, and not in connection with an Initial Public
Offering, and: 

  
 -3- 













 (A)        if the Common Stock is
traded on a securities exchange, the fair market value shall be deemed to be the product of (x) the average of the closing prices over a five (5) day period ending three days before the day the then-current fair market value of the
securities is being determined and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise; or 

(B)        if the Common Stock is traded over-the-counter, the fair market value shall be deemed to be the product of (x) the average of the closing bid and asked prices quoted on the NASDAQ system (or similar system) over the five (5) day
period ending three days before the day the then-current fair market value of the securities is being determined and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise;

 (iii)        if at any time the Common Stock is not listed on any securities
exchange or quoted in the over-the-counter market, the fair market value of Preferred Stock shall be the product of (x) the fair market: value of Common Stock, as
determined in good faith by its Board of Directors and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise, provided that in the event that the exercise is in connection
with a Merger Event, the fair market value of Preferred Stock shall be deemed to be the per share value received by the holders of the Company’s Preferred Stock on a common equivalent basis pursuant to such Merger Event. 

Upon partial exercise by either cash or Net Issuance, the Company shall promptly issue a new warrant representing the remaining number of
shares purchasable hereunder. All other terms and conditions of such new Warrant 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 previously exercised
as to all Preferred Stock subject hereto, and if the fair market value of one share of the Preferred Stock is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(a) (even if
not surrendered) immediately before its expiration. For purposes of such automatic exercise, the fair market value of one share of the Preferred 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 the Warrantholder of the number of shares of Preferred Stock, if any, the Warrantholder is to receive by reason of
such automatic exercise. 
 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 its Preferred
Stock to provide for the exercise of the rights to purchase Preferred Stock as provided for herein, and shall have authorized and reserved a sufficient dumber of shares of its Common Stock to provide for the conversion of the Preferred Stock
issuable hereunder.

 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 Exercise Price then in effect. 
 SECTION 6. NO RIGHTS AS
SHAREHOLDER/STOCKHOLDER. 
 This Agreement does not entitle the Warrantholder to any voting rights or other rights as a
shareholder/stockholder f the Company prior to the exercise of this Warrant.

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 in Section 12(f) below. 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 shares of Preferred Stock purchasable hereunder are subject adjustment, as follows: 

(a)        Merger Event. If at any time there shall be Merger Event, then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall thereafter be entitled to receive, upon exercise of this Warrant, the number of shares of preferred stock or other securities or property of the successor corporation
resulting from such Merger Event that would have been issuable if Warrantholder had exercised this Warrant immediately prior to the Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of
Directors) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Warrantholder after the Merger Event to the end that the provisions of this Warrant (including adjustments of the Exercise.
Price and number of shares of Preferred Stock purchasable) shall be applicable in their entirety, and to the greatest extent possible. Without limiting the foregoing, in connection with any Merger Event, upon the closing thereof, the successor or
surviving entity shall assume the obligations of this Warrant. In connection with a Merger Event and upon Warrantholder’s written election to the Company at least five (5) days prior to the closing thereof, the Company shall cause this
Warrant to be exchanged for the consideration that Warrantholder would have received if Warrantholder chose to exercise its right to have shares issued pursuant to the Net Issuance provisions of this Warrant without actually exercising such right,
acquiring such shares and exchanging such shares for such consideration 

(b)        Reclassification of Shares. Except as set forth in Section 8(a), if the Company
at any time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other
class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the


  
 -5- 













 
purchase rights under this Warrant immediately prior to such combination, reclassification, exchange, subdivision or other change. 

(c)        Subdivision or Combination of Shares. If the Company at any time shall combine or
subdivide its Preferred Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, and the number of shares of Preferred Stock issuable upon exercise of this .Warrant shall be proportionately increased, or
(ii) in the case of a combination, the Exercise Price shall be proportionately increased, and the number of shares of Preferred Stock issuable upon the exercise of this Warrant shall be proportionately decreased. pay a dividend with respect to
the Preferred Stock payable in Preferred Stock. 
 (d)        Stock Dividends. If the Company
at any time while this Warrant is outstanding and unexpired shall: 
 (i)        pay
a dividend with respect to the Preferred Stock payable in Preferred Stock, then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price
determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Preferred Stock outstanding immediately prior to such
dividend or distribution, and (B) the denominator of which shall be the total number of shares of Preferred Stock outstanding immediately after such dividend or distribution; or 

(ii)        make any other distribution with respect to Preferred Stock (or stock into
which the Preferred Stock is convertible), 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 the Warrantholder shall receive upon
exercise of this Warrant a proportionate share of any such distribution as though it were the holder of the Preferred Stock (or other stock for which the Preferred Stock is convertible) as of the record date fixed for the determination of the
stockholders of the Company entitled to receive such distribution. 
 (e)        Antidilution
Rights. Antidilution rights applicable to the Preferred Stock purchasable hereunder are as set forth in the Charter and shall be applicable with respect to the Preferred Stock issuable hereunder. The Company shall promptly provide the
Warrantholder with any restatement, amendment, modification or waiver of the Charter; provided, that no such amendment, modification or waiver shall impair or reduce the antidilution rights applicable to the Preferred Stock as of the date hereof
unless such amendment, modification or waiver applies to all then-outstanding shares of Preferred Stock. For the avoidance of doubt, there shall be no duplicate anti-dilution adjustment pursuant to this Section 8(e), the forgoing
Section 8(d) and the Charter. 
 (f)        Notice of Adjustments. If: (i) the
Company shall declare any dividend or distribution upon outstanding shares of the Preferred Stock, whether in stock, cash, property or other securities; (ii) the Company shall offer for subscription pro rata to the holders of outstanding shares
of the Preferred Stock any additional shares of stock of any class or series or other rights (other than pursuant to contractual pre-emptive rights); (iii) there shall be any


  
 -6- 













 
Merger Event; (iv) there shall be an Initial Public Offering; (v) the Company shall sell, lease, license or otherwise transfer all or substantially all of its assets; or (vi) 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 the Warrantholder: (A) at least fifteen (15) 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 Preferred Stock shall be entitled thereto) or for determining rights to vote in
respect of such Merger Event, dissolution, liquidation or winding up; (B) in the case of any such Merger Event, sale, lease, license or other transfer of all or substantially all assets, dissolution, liquidation or winding up, at least fifteen
(15) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of Preferred Stock shall be entitled to exchange their Preferred Stock for securities or other property deliverable
upon such Merger Event, dissolution, liquidation or winding up); and (C) in the case of an Initial Public Offering, the Company shall give the Warrantholder at least fifteen (15) days’ written notice prior to the filing of the
registration statement in connection therewith. 
 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 number of shares subject to purchase hereunder after giving effect to such adjustment, and shall be given in the manner set forth in Section 12(f). 

(g)        Timely Notice. Failure to timely provide such notice required by Section 8(f)
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. 

(h)        “Pay to Play” Rights. In the event that any “pay to play” terms
or conditions (i.e. terms or conditions that require a holder of the Preferred Stock to purchase securities in a future round of equity financing or else lose the benefit of anti-dilution protections applicable to shares of Preferred Stock or have
such shares of Preferred Stock automatically convert into common stock or another class or series of capital stock) in the Charter are triggered in connection with any equity financing (a “Trigger Event”), then, in each such event, the
purchase rights under this Agreement shall automatically adjust to provide the Warrantholder, upon the later exercise hereof, with the same securities and/or rights that the Warrantholder would have received had the Warrantholder (x) exercised
this Warrant prior to such Trigger Event, and (y) participated in such equity financing in an amount sufficient to be deemed to have fully participated for purposes of such “pay to play” provision. For the avoidance of doubt, the
foregoing shall not alter the impact of a Trigger Event and any such “pay to play” terms or conditions upon shares of Preferred Stock of the Company held by the WarrantHolder as of the effective date thereof.

otherwise transfer or dispose of, directly or indirectly, this Warrant, the Preferred Stock or other shares of capital stock issuable upon exercise of this Warrant (or the conversion of any such
shares), or any other securities of the Company or (ii) enter into any swap or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of this Warrant, the Preferred Stock or other shares of capital
stock issuable upon exercise of this Warrant (or the conversion of any such shares), or any other securities of the Company (excluding securities acquired in the Initial Public Offering or in the public market after the Initial Public Offering),
whether any transaction described in clause (i) or (ii) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the date of the filing of the registration statement relating to the Initial Public
Offering with the SEC and ending 180 days after the date of the final prospectus relating to the Initial Public Offering (plus up to an additional 34 days to the extent requested by the managing underwriters for such offering in order to address
Rule 2711 (f) of the National Association of Securities Dealers, Inc. or any similar successor provision) and (b) to execute any agreement reflecting clause (a) above as may be requested by the Company or the managing underwriters of the
Initial Public Offering; provided, that all directors and officers of the Company, and all holders of one percent (1%) or more of the Company’s Common Stock (calculated on a fully-diluted,
as-exercised, as-converted basis) enter into similar agreements with the Company and/or managing underwriter; provided, further, that if the Company or
managing underwriter releases any such director, officer or stockholder from his or its obligations under such agreement prior to the expiration thereof, the Warrantholder shall thereupon automatically be released from its obligations under this
Section 10(f) and its agreement with the Company and/or managing underwriter to the same extent. In order to enforce the foregoing, the Company may impose stop-transfer instructions with respect to such securities until the end of such lock-up period and may cause such securities to bear a legend setting forth such restriction until the end of such lock-up period. The underwriters for the Initial Public
Offering are intended third party beneficiaries of this Section 10(f) and shall have the right, power and authority to enforce the provisions hereof as though they were parties hereto. 

SECTION 11. TRANSFERS.

compliance with applicable federal and state securities laws and with the provisions of this Section 11, 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 the holder hereof, when this Warrant shall have been properly 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 ditched 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. Until the Company receives such Transfer Notice, the Company may treat the registered owner hereof as the owner for all purposes. Neither this Warrant nor the
shares of capital stock issuable upon exercise of this Warrant shall be sold or transferred unless either (i) they first shall have been registered under the Act, or (ii) the Company first shall have been furnished with an opinion of legal
counsel, reasonably satisfactory to the Company, to the 

  
 -11- 













 
effect that such sale or transfer is exempt from the registration requirements of the Act; provided, that the Company shall not require a legal opinion in connection with any transfer by
Warrantholder of this Warrant and/or any shares of Preferred Stock issued upon exercise hereof to an Affiliate of Warrantholder, provided that such transferee (i) is an “accredited investor” within the meaning of the Securities and
Exchange Rule 501 of Regulation D, as presently in effect, and (ii) agrees in writing with the Company to be bound by all of the obligations of the Warrantholder hereunder. At all times prior to the Initial Public Offering, the Warrantholder
shall not, without the prior written consent of the Company, (x) transfer this Warrant or any shares of Preferred Stock issued upon any exercise hereof to a person or entity that directly competes with the Company, except in connection with a
Merger Event where the acquiring or surviving person or entity is such a direct competitor, and (y) transfer this Warrant to any non-Affiliate except in whole. As used herein, an “Affiliate” of
the Warrantholder means any person or entity directly or indirectly controlling, controlled by or under common control with the Warrantholder. Each certificate representing shares of capital stock issuable upon exercise of this Warrant shall bear a
legend substantially in the following form: 
 “The securities represented by this certificate have not been registered under the
Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such securities are registered under such Act or, subject to Section 11 of that certain Warrant Agreement dated
November 7, 2012 between the Company and Hercules Technology Growth Capital, Inc., an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required.” 

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 expressly agrees that
it shall not oppose an application by the other party or any other person entitled to the benefit of this Warrant requiring specific performance of any or all provisions hereof or enjoining the other party from continuing to commit any such breach
of this Warrant. 
 (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 the Warrantholder against impairment. 

  
 -12- 













 (d)        Attorney’s Fees. In any
litigation, arbitration or court proceeding between the Company and the Warrantholder relating hereto, the prevailing party shall be entitled to reasonable attorneys’ fees and expenses and all costs of proceedings incurred in enforcing this
Warrant. For the purposes of this Section 12(d), reasonable attorneys’ fees shall include without limitation fees incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding
or other activity of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and third party examinations; and (v) post-judgment motions and proceedings of any kind, including without limitation any
activity taken to collect or enforce any judgment. 
 (e)        Severability. In the event
any one or more of the provisions of this Warrant shall for any reason be held invalid, illegal or unenforceable, the remaining provisions of this Warrant shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by
a mutually acceptable valid, legal and enforceable provision, which comes closest to the intention of the parties underlying the invalid, illegal or unenforceable provision. 

(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:

or to such other address as each party may designate for itself by like notice. 

(g)        Entire Agreement: Amendments. This Agreement constitute the entire agreement and
understanding of the parties hereto in respect of the subject matter hereof, and supersede and replace in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect
to the subject matter hereof. None of the terms of this Warrant may be amended except by an instrument executed by each of the parties hereto. 

(h)        Headings. The various headings in this Warrant are inserted for convenience only and
shall not affect the meaning or interpretation of this Warrant or any provisions hereof. 

(i)        Advice of Counsel. Each of the parties represents to each other party hereto that it
has discussed (or had an opportunity to discuss) with its counsel this Warrant and, specifically, the provisions of Sections 12(m), 12(n), 12(o), 12(p)and 12(q). 

(j)        No Strict Construction. The parties hereto have participated jointly in the
negotiation and drafting of this Warrant. In the event an ambiguity or question of intent or interpretation arises, this Warrant shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any provisions of this Warrant. 

(k)        No Waiver. No omission or delay by either party at any time to enforce any right or
remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the other party at any time designated, shall be a waiver of any such right or remedy to which such party is entitled, nor shall it in any way
affect the right of such party to enforce such provisions thereafter. 
 (l)        Survival.
All agreements, representations and warranties contained in this Warrant or in any document delivered pursuant hereto shall be for the benefit of Warrantholder 

  
 -14- 













 
or the Company, as the case may be, and shall survive the execution and delivery of this Warrant and the expiration or other termination of this Warrant. 

(m)        Governing Law. This Agreement shall be governed by, and construed and enforced in
accordance with, (i) to the extent applicable, the Delaware General Corporation Law, and (ii) otherwise, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other
jurisdiction. 
 (n)        Consent to Jurisdiction and Venue. All judicial proceedings
arising in or under or related to this Warrant shall be brought in any state or federal court of competent jurisdiction located in the State of California. By execution and delivery of this Warrant, each party hereto generally and unconditionally:
(a) consents to personal jurisdiction in Santa Clara County, State of California; (b) waives any objection as to jurisdiction or venue in Santa Clara County, State of California; (c) agrees not to assert any defense based on lack of
jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Warrant. Service of process on any party hereto in any action arising out of or relating to this
Warrant shall be effective if given in accordance with the requirements for notice set forth in Section 12(f), and shall be deemed effective and received as set forth in Section 12(f). Nothing herein shall affect the right to serve process
in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction. 

(o)        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 the
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. 
 (p)        Arbitration. If the Mutual Waiver of Jury Trial
set forth in Section 12(o) is ineffective or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance proceeding shall be conducted in San Francisco County, California, with California 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. 

  
 -15- 














(q)        Pre-arbitration 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(n), 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. 

(r)        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. 
 (s)        Specific Performance. The parties hereto hereby declare that it is
impossible to measure in money the damages which will accrue to a party by reason of the other party’s failure to perform any of its respective obligations under this Warrant and agree that the terms of this Warrant shall be specifically.
