Exhibit 10.50

ARTHROCARE CORPORATION

AMENDED AND RESTATED 2003 INCENTIVE STOCK PLAN

RESTRICTED STOCK BONUS AGREEMENT

This Restricted Stock Bonus Agreement (the “Agreement”) is made as of                     , by and between ArthroCare Corporation, a Delaware corporation (the “Company”),                      (“Participant”). Capitalized terms not defined herein shall have the meanings assigned to such terms in the Company’s Amended and Restated 2003 Incentive Stock Plan (the “Plan”).

(a) Pursuant to the Plan and subject to the terms and conditions of this Agreement, on the Issuance Date (as defined below), the Company will issue to Participant              shares of the Company’s Stock (the “Shares”) for good and valuable consideration which the Company has determined to exceed the par value of the Company’s Stock. The term “Shares” refers to the issued Shares and all securities received in replacement of or in connection with the Shares pursuant to stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which Participant is entitled by reason of Participant’s ownership of the Shares.

(b) The parties agree that the Shares have a Fair Market Value of $             per share as of the date of this Agreement.

(c) The issuance of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution of this Agreement by the parties or on such other date as the Company and Participant shall agree (the “Issuance Date”). As soon as practicable following the Issuance Date, the Company will deliver to Participant a certificate representing the Shares to be issued to Participant (which shall be issued in Participant’s name).

(a) Subject to the provisions of Section 2(b) below, if Participant ceases to be an Employee, director or consultant of the Company for any or no reason, all of the Unreleased Shares (as defined below) shall thereupon be forfeited immediately and without any further action by the Company (the “Forfeiture Restriction”). Upon the occurrence of such a forfeiture, the Company shall become the legal and beneficial owner of the Shares being forfeited and all rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Shares being forfeited by Participant.

(b) Provided that Participant continues to serve as an Employee, director or consultant of the Company on such date, all of the Shares shall be released from the Forfeiture Restriction as follows:

(i) one-fifth (1/5) of the Shares shall be released from the Forfeiture Restriction on the first anniversary of the date of the Vesting Commencement Date;

(ii) one-fifth (1/5) of the Shares shall be released from the Forfeiture Restriction on the second anniversary of the date of the Vesting Commencement Date;

(iii) one-fifth (1/5) of the Shares shall be released from the Forfeiture Restriction on the third anniversary of the date of the Vesting Commencement Date.

(iv) one-fifth (1/5) of the Shares shall be released from the Forfeiture Restriction on the fourth anniversary of the date of the Vesting Commencement Date.

(v) one-fifth (1/5) of the Shares shall be released from the Forfeiture Restriction on the fifth anniversary of the date of the Vesting Commencement Date.

For purposes of this Section 2(b), the term “Vesting Commencement Date” shall mean             .

(c) Any of the Shares which, from time to time, have not yet been released from the Forfeiture Restriction are referred to herein as “Unreleased Shares.”

(a) Participant hereby authorizes and directs the secretary of the Company, or such other person designated by the Company from time to time, to transfer any Unreleased Shares which are forfeited pursuant to Section 2 above from Participant to the Company.

(b) To insure the availability for delivery of Participant’s Unreleased Shares upon forfeiture under Section 2, Participant hereby appoints the secretary, or any other person designated by the Company as escrow agent from time to time, as its attorney-in-fact to sell, assign and transfer unto the Company, such Unreleased Shares, if any, forfeited by Participant pursuant to Section 2 and shall, upon execution of this Agreement, deliver and deposit with the secretary of the Company, or such other person designated by the Company, the share certificate(s) representing the Unreleased Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit A. The Unreleased Shares and stock assignment shall be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of the Company and Participant attached as Exhibit B hereto, until the Shares are forfeited as provided in Section 2, until such Unreleased Shares are fully released from the Forfeiture Restriction, or until such time as this Agreement no longer is in effect. Upon release of the Unreleased Shares from the Forfeiture Restriction, the escrow agent shall promptly deliver to Participant the certificate or certificates representing such Shares in the escrow agent’s possession belonging to Participant, and the escrow agent shall be discharged of all further obligations

2

hereunder; provided, however, that the escrow agent shall nevertheless retain such certificate or certificates as escrow agent if so required pursuant to other restrictions imposed pursuant to this Agreement.

(c) The Company, or its designee, shall not be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment.

4. Taxation Representations. In connection with the purchase of the Shares, Participant represents to the Company the following:

(a) Participant acknowledges that he or she has been informed that unless an election is filed by Participant with the Internal Revenue Service and, if necessary, the proper state taxing authorities, within thirty (30) days of the date of this Agreement, electing pursuant to Section 83(b) of the Internal Revenue Code of 1986, as amended (and similar state tax provisions if applicable), to be taxed currently on the fair market value of the Shares on the date of this Agreement, there will be a recognition of taxable income to Participant equal to the fair market value of the Shares at the time the Forfeiture Restriction lapses. Participant represents that Participant has consulted any tax consultant(s) Participant deems advisable in connection with the receipt or disposition of the Shares or the filing of the election under Section 83(b) and similar tax provisions and that Participant is not relying on the Company for any tax advice.

PARTICIPANT ACKNOWLEDGES THAT IT IS PARTICIPANT’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PARTICIPANT’S BEHALF.

(b) Participant has reviewed with his or her own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Participant understands that Participant (and not the Company) shall be responsible for his or her own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. Participant has reviewed this Agreement in its entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully understands all provisions of this Agreement.

(c) Notwithstanding anything to the contrary in this Agreement, the Company or any Subsidiary shall have the authority and the right to deduct or withhold, or require Participant to remit to the Company, an amount sufficient to satisfy federal, state, local and foreign taxes (including Participant’s FICA obligation) required by law to be withheld with respect to any taxable event concerning the Participant arising as a result of this Agreement. The Committee may in its discretion and in satisfaction of the foregoing requirement allow Participant to elect to have the Company withhold shares of Stock otherwise issuable under this Agreement (or allow the return of shares of Stock) having a Fair Market Value equal to the sums required to be withheld.

3

(a) Unreleased Shares Not Transferable. Unless otherwise permitted by the Committee pursuant to the Plan, no Unreleased Shares or any interest or right therein or part thereof shall be subject to any lien, obligation, or liability of the Participant or any other party than the Company or a Subsidiary; provided, however, that this Section 5(a) shall not prevent transfers by will or by applicable laws of descent and distribution. In case of a permitted transfer, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Agreement, and there shall be no further transfer of such Shares except in accordance with the terms of this Section. Any transferee shall acknowledge the same by signing a copy of this Agreement. Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws.

(b) Legends. The certificate or certificates representing the Shares shall bear the following legend (as well as any legends required by applicable state and federal corporate and securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

(c) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(d) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

(e) Removal of Legend. After such time as the Forfeiture Restriction shall have lapsed with respect to the Shares, and upon Participant’s request, a new certificate or certificates representing such Shares shall be issued without the legend referred to in Section 5(a)(i), and delivered to Participant.

6. No Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Participant’s employment or consulting relationship, for any reason, with or without Cause.

7. Rights as Stockholder. Except as otherwise provided herein, upon delivery of the Shares to the escrow holder pursuant to Section 3, Participant shall have all the rights of a

4

stockholder with respect to said shares, subject to the restrictions herein, including the right to vote the shares and to receive all dividends or other distributions paid or made with respect to the Shares; provided, however, that any and all shares of Stock received by Participant with respect to such Shares as a result of stock dividends, stock splits or any other form of recapitalization shall also be subject to the Forfeiture Restriction until such restrictions on the underlying Shares lapse or are removed pursuant to this Agreement.

(a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law.

(b) Entire Agreement; Enforcement of Rights. The Plan is incorporated herein by reference. This Agreement and the Plan set forth the entire agreement and understanding of the parties relating to the subject matter herein and merge all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. Notwithstanding anything to the contrary anywhere else in this Agreement, the grant of the Shares is subject to the terms, definitions and provisions of the Plan, which is incorporated herein by reference. Any of your rights hereunder shall be in addition to any rights you may otherwise have under benefit plans or agreements of the Company to which you are a party or in which you are a participant, including, but not limited to, any Company sponsored employee benefit plans, stock option plans, severance plans or severance agreements. The provisions of this Agreement shall not in any way limit your rights under such other plans and agreements.

(c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

(d) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto.

(e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient when delivered personally or sent by telegram or fax or 48 hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such party’s address or fax number as set forth below or as subsequently modified by written notice.

5

(f) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

(g) Successors and Assigns. The rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Participant under this Agreement may only be assigned with the prior written consent of the Company.
