WARRANT TO PURCHASE STOCK

Issuer: BIOLASE, INC., a Delaware corporation (the “Company”)

Number of Shares: the number of fully paid and non-assessable shares (after taking into account adjustments made pursuant to stock splits, reverse stock splits and other events specified in Article 2) of Common Stock obtained by dividing (i) $120,000, by (ii) the applicable Exercise Price at the time this Warrant is exercised.

Class of Stock: Common Stock

Exercise Price per Share: $0.4656 (as may be adjusted in accordance with Article 2)

Issue Date: March 6, 2018

Expiration Date: March 6, 2028

THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other good and valuable consideration, WESTERN ALLIANCE BANK, or its assignees (“Holder”) is entitled to purchase the number of fully paid and nonassessable shares of the Company’s capital stock set forth above (the “Shares”) at the Exercise Price per Share set forth above, as the same may be from time to time adjusted pursuant to Article 2 hereof and subject to the provisions and upon the terms and conditions set forth in this Warrant.

Article 1eXERCISE.

1.1Method of Exercise.  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.  Holder may exercise this Warrant by delivering a duly executed Notice of Exercise, in substantially the form attached hereto as Appendix 1, to the principal office of Company.  Unless Holder is exercising the conversion right set forth in Section 1.2, Holder shall also deliver to Company an amount equal to the aggregate Exercise Price for Shares being purchased, by check or wire.

1.2Conversion 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 Shares or other securities otherwise issuable upon exercise of this Warrant minus the aggregate Exercise Price of such Shares by (b) the fair market value of one Share.  The fair market value of Shares shall be determined pursuant to Section 1.3.

1.3Fair Market Value.  If the Shares are traded 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 stock into which the Shares are convertible) reported for the business day immediately before Holder

1693899.2

delivers its Notice of Exercise to the Company.  If the Shares are not traded in a public market, the Board of Directors of 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 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 Company.  In all other circumstances, such fees and expenses of such investment banking firm shall be paid by Holder.

1.4Delivery of Certificate and New Warrant.  Promptly (and in no event more than 3 business days after exercise) after Holder exercises or converts this Warrant, Company shall deliver to Holder certificates for Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing Shares not yet acquired.

1.5Replacement of Warrant.  On receipt of evidence reasonably satisfactory to 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 Company or, in the case of mutilation, on surrender and cancellation of this Warrant, Company at its expense shall execute and deliver a replacement Warrant.

1.6Sale, Merger, or Consolidation of Company.  For the purpose of this Warrant, “Acquisition” means any sale, license, or other disposition of all or substantially all of the assets of Company, or any reorganization, consolidation, or merger of Company where the holders of Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction.  Upon the closing of any Acquisition, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on the record date for the Acquisition and subsequent closing, and the Exercise Price shall be adjusted accordingly; provided that if pursuant to such Acquisition the entire outstanding class of Shares issuable upon exercise of the unexercised portion of this Warrant are cancelled and the total consideration payable to the holders of such class of Shares consists entirely of cash, then, upon payment to the holder of this Warrant of an amount equal to the amount such holder would receive if such holder held Shares issuable upon exercise of the unexercised portion of this Warrant and such Shares were outstanding on the record date for the Acquisition less the aggregate Exercise Price of such Shares, this Warrant shall be cancelled.

1.7Automatic Cashless Exercise upon Expiration.  In the event that, upon the Expiration Date or other termination of the warrant, the fair market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Exercise Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities) issued upon such exercise to Holder.

Article 2ADJUSTMENTS.

2.1Stock Dividends, Splits, Etc.   If Company declares or pays a dividend on its common stock (or Shares, if Shares are securities other than common stock) payable in common stock or

1693899.2

2

other securities or property, subdivides the outstanding common stock into a greater amount of common stock, or, if Shares are securities other than common stock, subdivides Shares in a transaction that increases the amount of common stock into which Shares are convertible, 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 Shares on the record date the dividend or subdivision occurred since the original issue date of this Warrant.

2.2Reclassification, Recapitalization, Exchange or Substitution.  Upon any reclassification, recapitalization, 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 Shares if this Warrant had been exercised immediately before such reclassification, recapitalization, exchange, substitution, or other event. 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 Exercise 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, recapitalizations, exchanges, substitutions, or other events.

2.3Adjustments for Combinations, Etc.  If the outstanding Shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Exercise Price shall be proportionately increased and the number of Shares as to which this warrant is exercisable shall be proportionately decreased.

2.4Adjustments for Diluting Issuances.  In the event of the issuance (a “Diluting Issuance”) by Company, after the Issue Date of the Warrant, of any Additional Shares of Common Stock (as defined in the Company’s Certificate of Incorporation) at a price per share less than the then Exercise Price, then the number of shares of common stock issuable upon conversion of the Shares, and the conversion price, shall be adjusted in accordance with those provisions (the “Provisions”) of Company’s Certificate of Incorporation which apply to Diluting Issuances with the same effect as though the shares were outstanding at the time of the diluting issuance.  Company agrees that the Provisions, as in effect on the Issue Date, shall be deemed to remain in full force and effect during the term of the Warrant notwithstanding any subsequent amendment, waiver or termination thereof by Company’s shareholders.  Under no circumstances shall the aggregate Exercise Price payable by Holder upon exercise of the Warrant increase as a result of any adjustment arising from a Diluting Issuance.

2.5Reserved.

2.6No Impairment.  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 Company, but shall at all times in good faith assist in carrying out of 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 Company takes any action affecting Shares or its common stock as described above

1693899.2

3

that adversely affects Holder’s rights under this Warrant, the Exercise 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 such action is offset and the aggregate Exercise Price of this Warrant is unchanged.

2.7Fractional Shares.  No fractional Shares shall be issuable upon exercise or conversion of the Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share.  If a fractional share interest arises upon any exercise or conversion of the Warrant, Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying the fractional interest by the fair market value of a full Share.

2.8Certificate as to Adjustments.  Upon each adjustment of the Exercise Price, Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth the Exercise Price in effect upon the date thereof and the series of adjustments leading to such Exercise Price, and the facts upon which such adjustment is based.
