COMMON STOCK PURCHASE WARRANT

PLC SYSTEMS, INC.

Warrant Shares: 943,596  Date: May 9, 2014

THIS COMMON STOCK PURCHASE WARRANT (this “Warrant”) certifies that, for value received, GBS Venture Partners Limited, as trustee for GBS BioVentures III or its registered assigns (the “Holder”), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, immediately after the Effective Time (as defined in the Agreement and Plan of Merger (the “Merger Agreement”) by and among PLC Systems, Inc., a Yukon Territory corporation (the “Company”), PLC Systems Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of the Company, and Viveve, Inc., a Delaware corporation), to purchase and receive from the Company, 943,596 shares (after giving effect to the 1 for 100 reverse stock split contemplated by the Merger Agreement, collectively, the “Warrant Shares”) of the Company’s common shares, without par or nominal value (“Common Stock”). The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 1(b).

Section 1.       Exercise.

a)     Exercise of Warrant. This Warrant shall be deemed automatically exercised in whole to purchase all of the Warrant Shares, without any action being required on the part of the Holder, immediately after the Effective Time (the “Automatic Exercise Time”). The Holder shall not be required to physically surrender this Warrant to the Company upon exercise.

b)     Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $0.0000001 (the “Exercise Price”).

c)     Cashless Exercise. This Warrant shall be exercised, at the Automatic Exercise Time, in whole by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the Private Placement Price Per Share;

1

(B) = the Exercise Price of this Warrant; and

(X) = the total number of Warrant Shares for which this Warrant is then exercisable.

For purposes of this Agreement, “Private Placement Price Per Share” means the price for one share of Common Stock sold in the Private Placement (as defined in the Merger Agreement).

d)            Mechanics of Exercise.

i.     Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by Computershare Trust Company, N.A., the current transfer agent for the Company, or any successor transfer agent of the Company, to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”), and otherwise by physical delivery to the Holder within three (3) business days after the Automatic Exercise Time. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the Automatic Exercise Time.

ii.     No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

iii.     Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder.

Section 2.

a)            Stock Dividends and Splits. Other than the 1 for 100 reverse stock split contemplated by the Merger Agreement, if the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 2(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution (provided that if the declaration of such dividend or distribution is rescinded or otherwise cancelled, then such adjustment shall be reversed upon notice to the Holder of the termination of such proposed declaration or distribution as to any unexercised portion of this Warrant at the time of such rescission or cancellation) and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

2

b)            Calculations. All calculations under this Section 2 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 2, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

c)            Notice to Holder. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 2, the Company shall promptly send to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment at the following address:

Section 3.               Transfer of Warrant.

a)            Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 3(c) hereof, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon a written assignment of this Warrant in form and substance reasonably acceptable to the Company, duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such payment, if such payment shall be required, the Company shall execute and deliver a new Warrant in the name of the assignee and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b)            Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company and any agent of the Company may deem and treat the person or entity in whose name this Warrant is duly registered on the Warrant Register as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary. In the event of an assignment or transfer of this Warrant, the assignee or transferee shall be deemed a registered holder hereunder on the date the assignment form referred to in Section 2(a) above is duly executed and delivered to the Company.

3

c)            Transfer Restrictions. If any transfer of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, to the effect that such transfer does not require registration of such transferred Warrant Shares under the Securities Act.

d)            Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that (x) it is acquiring this Warrant for its own account and not with a view to or for distributing or reselling this Warrant, (y) upon any exercise hereof, it will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities laws, except pursuant to sales registered or exempted under the Securities Act and any applicable state securities laws, and (z) it is an “accredited investor,” as defined in Regulation D promulgated under the Securities Act.

Section 4.              Miscellaneous.

a)            No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 1(a).

b)            Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and of the ownership hereof or thereof, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of this Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c)            Automatic Termination. In the event of any termination of the Merger Agreement, pursuant to the terms thereof without the Merger (as defined in the Merger Agreement) being consummated, this Warrant shall automatically become null and void and of no further force or effect.

d)            Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a business day, then, such action may be taken or such right may be exercised on the next succeeding business day.

e)            Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the due exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any of the markets or exchanges on which the Common Stock of the Company is listed or quoted for trading. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

4

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of continuance or through any 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 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 to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

f)             Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof. Each party hereby irrevocably submits to the exclusive jurisdiction of the Delaware Court of Chancery or any other state or federal courts sitting in the State of Delaware for the adjudication of any dispute hereunder.

g)            Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered under the Securities Act or other applicable securities laws, will have restrictions upon resale imposed by applicable securities laws.

h)            Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

i)              Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

5

j)             Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k)            Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder.

l)             Amendment. This Warrant may be modified or amended or the provisions hereof waived upon the written consent of the Company and the Holder.

m)           Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n)            Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.
