 WARRANT
TO PURCHASE SHARES OF COMMON STOCK 
  

			
	Company:	    	Macro Holding, Inc., a Delaware corporation
	Number of Shares:	    	35,000
	Class of Security:	    	Common Stock
	Initial Exercise Price:	    	$4.00 per share
	Issue Date:	    	July 12, 2002
	Expiration Date:	    	July 12, 2009 (Subject to Article 4.1)

 THIS WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and for other good and
valuable consideration, COMERICA BANK-CALIFORNIA or its assignee (“Holder”) is entitled to purchase the number of fully paid and nonassessable Shares of the class of securities (the “Shares”) of Macro Holding, Inc. (the
“Company”) at the initial exercise price per Share (the “Warrant Price”) all as set forth above and as adjusted pursuant to Article 2 of this warrant, subject to the provisions and upon the terms and conditions set forth in this
warrant. 
 ARTICLE 1. EXERCISE. 
 1.1
Method of Exercise. Holder may exercise this warrant by delivering this warrant and a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the Company a check for the aggregate Warrant Price for the Shares being purchased. 
 1.2 Conversion Right. In lieu of exercising this warrant as specified in Section 1.1, Holder may from time to time convert this warrant, in whole or in part, into a number of Shares determined by dividing
(a) the aggregate fair market value of the Shares or other securities otherwise issuable upon exercise of this warrant minus the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the
Shares shall be determined pursuant to Section 1.4 
 1.3 [Intentionally Deleted] 
 1.4 Fair Market Value. If the Shares are traded regularly in a public market, the fair market value of the Shares shall be the closing price of
the Shares (or the closing price of the Company’s security into which the Shares are convertible) reported for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. The foregoing notwithstanding, if Holder advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable investment banking firm to undertake such valuation. If the valuation of such investment banking firm is greater than that determined by the Board of Directors, then
all fees and expenses of such investment banking firm shall be paid by the Company. In all other circumstances, such fees and expenses shall be paid by Holder. 







 1.5 Delivery of Shares and New Warrant. Promptly after Holder exercises or converts this warrant,
the Company shall deliver to Holder a stock certificate representing the number of Shares purchased and, if this warrant has not been fully exercised or converted and has not expired, a new warrant representing the right to purchase the Shares not
so acquired. 
 1.6 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of
this warrant, the Company at its expense shall execute and deliver, in lieu of this warrant, a new warrant of like tenor. 
 1.7
Repurchase on Sale, Merger, or Consolidation of the Company. 
 1.7.1 “Acquisition.” For the purpose of this warrant,
“Acquisition” means any sale, license, or other disposition of all or substantially all of the assets (including intellectual property) of the Company to an unaffiliated third party (provided however, if there’s an Acquisition to an
affiliated third party, the affiliated third party shall assume this warrant on the existing terms and conditions), or any reorganization, consolidation, or merger of the Company where the holders of the Company’s securities before the
transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity or its parent after the transaction. 
 1.7.2 Assumption of Warrant. If upon the closing of any Acquisition the successor entity assumes the obligations of this warrant, then this warrant shall be exercisable for the same securities, cash, and property as would be payable
for the Shares issuable upon exercise of the unexercised portion of this warrant as if such Shares were outstanding on the record date for the Aquisition and subsequent closing. The Warrant Price shall be adjusted accordingly. The Company shall use
reasonable efforts to cause the surviving corporation to assume the obligations of this warrant. 
 1.7.3 Nonassumption. If upon the
closing of any Acquisition the successor entity does not assume the obligations of this warrant and Holder has not otherwise exercised this warrant in full, then Holder shall have the option to deem this warrant to have been automatically converted
pursuant to Section 1.2 and thereafter Holder shall participate in the Acquisition on the same terms as other holders of the same class of securities of the Company. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 
 2.1 Splits, Etc. If the Company declares or pays a
dividend on its Shares payable in Shares, or other securities, or subdivides the outstanding Shares into a greater amount of Shares, then upon exercise of this warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend or subdivision occurred. 
 2.2 Reclassification, Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise or
conversion of this warrant, Holder shall be entitled to receive, upon exercise or conversion of this warrant, the number and kind of securities and property that Holder would have received for the Shares if this warrant had been exercised
immediately before such reclassification, exchange, substitution, or other event. The Company or its successor shall promptly issue to Holder a new warrant for such new securities or other property. The new warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new
warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 







 2.3 Adjustments for Combinations, Etc. If the outstanding Shares are combined or consolidated, by
reclassification or otherwise, into a lesser number of Shares, the Warrant Price shall be proportionately increased and the number of Shares subject to purchase under this warrant shall be proportionately decreased. 
 2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of Shares issuable upon exercise of this warrant shall be subject to
adjustment, from time to time, in the manner set forth on Exhibit A, if attached, in the event of Diluting Issuances (as defined on Exhibit A). 
 2.5 No Impairment. The Company shall not, by amendment of its Certificate of Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this warrant by the Company, but shall at all times in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against impairment. If the Company takes any action affecting the Shares other than as described above (other than actions in the ordinary
course of business) that adversely affects Holder’s rights under this warrant, the Warrant Price shall be adjusted downward and the number of Shares issuable upon exercise of this warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this warrant is unchanged. 
 2.6 Certificate as to Adjustments. Upon each adjustment of the Warrant Price,
the Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written
request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 
 ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 
 3.1 Representations and Warranties. The Company hereby
represents and warrants to the Holder as follows: 
 (a) The initial Warrant Price referenced on the first page of this warrant is not greater
than the fair market value of the partnership units in the Borrower on the date of its last equity round. 
 (b) All Shares which may be
issued upon the exercise of the purchase right represented by this warrant, and all securities, if any, issuable upon conversion of the Shares, shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, and free of any
liens and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. 
 (c)
The Company’s capitalization table attached to this warrant is true and complete as of the Issue Date. 
 (d) Upon exercise of this
warrant, Holder will become the owner of the Shares with all the rights and obligations of a common shareholder of the Company.

or not a regular cash dividend; (b) to offer for subscription pro rata to the holders of any class or series of its Shares any additional Shares of any
class or series or other rights; (c) to effect any reclassification or recapitalization of Shares; or (d) to merge or consolidate with or into any other corporation, or sell, lease, license, or convey all or substantially all of its
assets, or to liquidate, dissolve or wind up, then, in connection with each such event, the Company shall give Holder (1) at least 20 days prior written notice of the date on which a record will be taken for such dividend, distribution, or
subscription rights (and specifying the date on which the holders of Shares will be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in (a) and (b) above; and (2) in the case of the
matters referred to in (c) and (d) above at least 20 days prior written notice of the date when the same will take place (and specifying the date on which the holders of Shares will be entitled to exchange their Shares for securities or
other property deliverable upon the occurrence of such event). 
 3.3 Information Rights. So long as the Holder holds this warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly after mailing, copies of all communiques to the shareholders of the Company, (b) within one hundred twenty (120) days after the end of each fiscal year of

fiscal year, the Company’s quarterly, unaudited financial statements. 
 ARTICLE 4.MISCELLANEOUS. 
 4.1 Term: Notice of Expiration. This warrant is exercisable in whole or in part, at any time and from time to time on or before the Expiration Date
set forth above; provided, however, that if the Company completes an initial public offering within the three-year period immediately prior to the Expiration Date, the Expiration Date shall automatically be extended until the third anniversary of
the effective date of Company’s initial public offering. If this warrant has not been exercised prior to the Expiration Date, this warrant shall be deemed to have been automatically exercised on the Expiration Date by “cashless”
conversion pursuant to Section 1.2. 
 4.2 Legends. This warrant shall be imprinted with a legend in substantially the following
form: 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHOUT AN
EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED. 
 4.3 Compliance with Securities Laws on Transfer. This warrant and the Shares issuable upon exercise of this warrant (and the securities issuable,

limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to an affiliate of Holder or if there

setting forth the name, address and taxpayer identification number of the transferee and surrendering this warrant to the Company for reissuance to the transferee(s) (and Holder, if applicable); provided, however, that Holder may transfer all
or part of this warrant to its affiliates, including, without limitation, Comerica Incorporated, at any time without notice to the Company, and such affiliate shall then be entitled to all the rights of Holder under this warrant and any related
agreements, and the Company shall cooperate fully in ensuring that any Shares issued upon exercise of this warrant are issued in the name of the affiliate that exercises the warrant. The terms and conditions of this warrant shall inure to the
benefit of, and be binding upon, the Company and the holders hereof and their respective permitted successors and assigns. Unless the Company is filing financial information with the SEC pursuant to the Securities Exchange Act of 1934, the Company
shall have the right to refuse to transfer any portion of this warrant to any person who directly or indirectly competes with the Company. 
 4.5 Notices. All notices and other communications from the Company to the Holder, or vice versa, shall be deemed delivered and effective when given personally or mailed by first-class registered or certified mail, postage prepaid, at

 EXHIBIT A 
 COMERICA BANK-CALIFORNIA 
 ANTI-DILUTION AGREEMENT 
 This Anti-dilution Agreement is entered into as of July 12, 2002, by and between Comerica Bank-California (“Purchaser”) and Macro Holding,
Inc. (“the Company”). 
 RECITALS 
 A. Concurrently with the execution of this Anti-dilution Agreement, the Purchaser is acquiring from the Company a Warrant to Purchase Shares of Common Stock (the “Warrant”) pursuant to which Purchaser has
the right to acquire from the Company Shares of the Company’s Common Stock (the “Shares”). 
 B. By this Anti-dilution
Agreement, the Purchaser and the Company desire to set forth the adjustment in the number of Shares issuable upon exercise of the Warrant as a result of a Diluting Issuance (as defined below). 
 C. Capitalized terms used herein shall have the same meaning as set forth in the Warrant. 
 NOW, THEREFORE, in consideration of the mutual promises, covenants and conditions hereinafter set forth, the parties hereto mutually agree as follows:

 1. Definitions. As used in this Anti-dilution Agreement, the following terms have the following respective meanings: 
 (a) “Option” means any right, option or warrant to subscribe for, purchase or otherwise acquire Shares or Convertible Securities of the Company.

 (b) “Convertible Securities” means any evidences of indebtedness, Shares of ownership interest or other securities directly or
indirectly convertible into or exchangeable for Shares. 
 (c) “Issue” means to grant, issue, sell, assume or fix a record date for
determining persons entitled to receive any security (including Options), whichever of the foregoing is the first to occur. 
 (d)
“Additional Shares” means all Shares (including reissued Shares) Issued (or deemed to be issued pursuant to Section 2) after the date of the Warrant. Additional Shares does not include, however, any Shares Issued in a transaction
described in Sections 2.1 and 2.2 of the Warrant; any Shares Issued upon conversion of Convertible Securities outstanding on the date of the Warrant; the Shares; or Shares Issued as incentive or in a nonfinancing transaction to employees, officers,
directors or consultants to the Company. 
 2. Deemed Issuance of Additional Shares. The Shares ultimately Issuable upon exercise of
an Option (including the Shares ultimately Issuable upon conversion or exercise of a Convertible Security Issuable pursuant to an Option) are deemed to be Issued when the Option is Issued. The Shares ultimately Issuable upon conversion or exercise
of a Convertible Security (other than a Convertible Security Issued pursuant to an Option) shall be deemed Issued upon Issuance of the Convertible Security. The maximum amount of Shares Issuable is determined without regard to any future adjustments
permitted under the instrument creating the Options or Convertible Securities. 







 3. Adjustment of Warrant Price for Diluting Issuances. 
 3.1 Full Ratchet Adjustment During First 12 Months. If the Company issues Additional Shares after the date of the Warrant but prior to the first
anniversary of the issuance of the Warrant and the consideration per Additional Share (determined pursuant to Section 9) is less than the Warrant Price in effect before such Issue (“First Year Diluting Issuance”), the Warrant Price in
effect immediately before such Issue shall be reduced concurrently with such Issue, to a price equal to the consideration per Additional Share received by the Company as a result of such First Year Diluting Issuance. 
 3.2 Weighted Average Adjustment After 12 Months. If the Company issues Additional Shares after the first anniversary date of the Warrant and the
consideration per Additional Share (determined pursuant to Section 9) is less than the Warrant Price in effect immediately before such Issue (a “Diluting Issuance”), the Warrant Price in effect immediately before such Issue shall be
reduced, concurrently with such Issue, to a price (calculated to the nearest hundredth of a cent) determined by multiplying the Warrant Price by a fraction: 
 (a) the numerator of which is the amount of Shares outstanding immediately before such Issue plus the amount of Shares that the aggregate consideration received by Company for the Additional Shares would purchase at
the Warrant Price in effect immediately before such Issue, and 
 (b) the denominator of which is the amount of Shares outstanding
immediately before such Issue plus the number of such Additional Shares. 
 3.3 Adjustment of Number of Shares. Upon each adjustment
of the Warrant Price, the number of Shares Issuable upon exercise of the Warrant shall be increased to equal the quotient obtained by dividing (a) the product resulting from multiplying (i) the number of Shares Issuable upon exercise of
the Warrant and (ii) the Warrant Price, in each case as in effect immediately before such adjustment, by (b) the adjusted Warrant Price. 
 3.4 Securities Deemed Outstanding. For the purpose of this Section 3, all Shares Issuable upon exercise of any outstanding Convertible Securities or Options, Warrants, or other rights to acquire securities of the Company shall
be deemed to be outstanding. 
 4. No Adjustment for Issuances Following Deemed Issuances. No adjustment to the Warrant Price shall be
made upon the exercise of Options or conversion of Convertible Securities. 
 5. Adjustment Following Changes in Terms of Options or
Convertible Securities. If the consideration payable to, or the amount of Shares Issuable by, the Company increases or decreases, respectively, pursuant to the terms of any outstanding Options or Convertible Securities, the Warrant Price shall
be recomputed to reflect such increase or decrease. The recomputation shall be made as of the time of the Issuance of the Options or Convertible Securities. Any changes in the Warrant Price that occurred after such Issuance because other Additional
Shares were Issued or deemed Issued shall also be recomputed. 
 6. Recomputation Upon Expiration of Options or Convertible
Securities. The Warrant Price computed upon the original Issue of any Options or Convertible Securities, and any subsequent adjustments based thereon, shall be recomputed when any Options or rights of conversion under 








 
Convertible Securities expire without having been exercised. In the case of Convertible Securities or Options for Shares, the Warrant Price shall be
recomputed as if the only Additional Shares Issued were the Shares actually Issued upon the exercise of such securities, if any, and as if the only consideration received therefor was the consideration actually received upon the Issue, exercise or
conversion of the Options or Convertible Securities. In the case of Options for Convertible Securities, the Warrant Price shall be recomputed as if the only Convertible Securities Issued were the Convertible Securities actually Issued upon the
exercise thereof, if any, and as if the only consideration received therefor was the consideration actually received by the Company (determined pursuant to Section 9), if any, upon the Issue of the Options for the Convertible Securities.

 7. Limit on Readjustments. No readjustment of the Warrant Price pursuant to Section 5 or 6 shall increase the Warrant Price
more than the amount of any decrease made in respect of the Issue of any Options or Convertible Securities. 
 8. 30 Day Options. In
the case of any Options that expire by their terms not more than 20 days after the date of Issue thereof, no adjustment of the Warrant Price shall be made until the expiration or exercise of all such Options. 
 9. Computation of Consideration. The consideration received by the Company for the Issue of any Additional Shares shall be computed as follows:

 (a) Cash shall be valued at the amount of cash received by the Company, excluding amounts paid or payable for accrued interest or
accrued dividends. 
 (b) Property. Property, other than cash, shall be computed at the fair market value thereof at the time of the
Issue as determined in good faith by the Board of Directors of the Company. 
 (c) Mixed Consideration. The consideration for
Additional Shares Issued together with other property of the Company for consideration that covers both shall be determined in good faith by the Board of Directors. 
 (d) Options and Convertible Securities. The Consideration per Additional Share for Options and Convertible Securities shall be determined by dividing: 
 (i) the total amount, if any, received or receivable by the Company for the Issue of the Options or Convertible Securities, plus the minimum amount of
additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon exercise of the Options or conversion of the
Convertible Securities, by 
 (ii) the maximum amount of Shares (as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) ultimately Issuable upon the exercise of such Options or the conversion of such Convertible Securities. 
 10. General. 
 10.1 Governing
Law. This Anti-dilution Agreement shall be governed in all respects by the laws of the State of California as such laws are applied to agreements between California residents entered into and to be performed entirely within California.








 10.2 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof
shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. 
 10.3 Entire Agreement. Except as set forth below, this Anti-dilution Agreement and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof. 
 10.4 Notices, etc. All notices and other communications required or permitted hereunder shall be in
writing and shall be mailed by first class mail, postage prepaid, certified or registered mail, return receipt requested, addressed (a) if to Purchaser at Purchaser’s address as set forth below, or at such other address as Purchaser shall
have furnished to the Company in writing, or (b) if to the Company, at the Company’s address set forth below, or at such other address as the Company shall have furnished to the Purchaser in writing. 
 10.5 Severability. In case any provision of this Anti-dilution Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions of this Anti-dilution Agreement shall not in any way be affected or impaired thereby. 
 10.6
Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Anti-dilution Agreement. 
 10.7 Counterparts. This Anti-dilution Agreement may be executed in any number of counterparts, each of which shall be an original, but all of
which together shall constitute one instrument.
