MINDBODY, INC.
OUTSIDE DIRECTOR COMPENSATION POLICY
Adopted and approved May 22, 2015, Originally effective as of June 18, 2015, and Amended and Restated as of December 14, 2017 
MINDBODY, Inc. (the “Company”) believes that the granting of compensation to the members of the Board of Directors (the “Board,” and members of the Board, the “Directors”) represents an effective tool to attract, retain and reward Directors who are not employees of the Company (the “Outside Directors”).

Unless otherwise defined herein, capitalized terms used in this Policy will have the meaning given such term in the Company’s 2015 Equity Incentive Plan (the “Plan”).  Each Outside Director will be solely responsible for any tax obligations incurred by such Outside Director as a result of the equity awards such Outside Director receives under this Policy.

Unless otherwise determined by the Board and/or the Compensation Committee, the Annual Award and/or any Pro Rata Annual Award (as defined below) shall be in the form of Restricted Stock Units.
If as of the date of an Annual Meeting, an Outside Director had not been an Outside Director as of the previous Annual Meeting, then he or she will not be granted a full Annual Award and instead will be granted a pro-rated Annual Award (“Pro Rata Annual Award”) with a total Value equal to the result of (x) $180,000 multiplied by (y) a fraction (i) the numerator of which is the

(d)    Value.  For purposes of this Policy, “Value” means (i) with respect to any award of RSUs, the Fair Market Value of the Shares subject thereto on the grant date of the award, or such other methodology the Board or the Compensation Committee of the Board (the “Compensation Committee”) may determine prior to the grant of the RSUs becoming effective, as applicable (ii) with respect to any award of stock options, the grant date fair value of such award as determined in accordance with ASC Topic 718 and the methods for determining stock-based compensation as set forth in the Company’s audited financial statements, or such other methodology the Board or the Compensation Committee may determine prior to the grant of the stock options.

(z)    The section labeled as “3.07    Survival” in the Credit Agreement shall now be Section 3.08 and the following Section 3.07 shall be added to the Credit Agreement in appropriate numerical order: 

3.07    Successor LIBOR.

Notwithstanding anything to the contrary in this Agreement or any other Loan Documents (including Section 11.01 hereof), if the Administrative Agent determines (which determination shall be conclusive absent manifest error), or the Borrower or Required Lenders notify the Administrative Agent (with, in the case of the Required Lenders, a copy to Borrower) that the Borrower or Required Lenders (as applicable) have determined, that:

(i)    adequate and reasonable means do not exist for ascertaining LIBOR for the applicable currency for any requested Interest Period because the LIBOR Screen Rate for the applicable currency is not available or published on a current basis and such circumstances are unlikely to be temporary; or

(ii)    the administrator of the LIBOR Screen Rate for the applicable currency or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which LIBOR for the applicable currency or the LIBOR Screen Rate for the applicable currency shall no longer be made available, or used for determining the interest rate of loans denominated in the applicable currency (such specific date, the “Scheduled Unavailability Date”), or

(iii)    syndicated loans currently being executed, or that include language similar to that contained in this Section, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to replace LIBOR for the applicable currency,

then, reasonably promptly after such determination by the Administrative Agent or receipt by the Administrative Agent of such notice, as applicable,  the Administrative Agent and the Loan Parties may amend this Agreement to replace LIBOR for the applicable currency with an alternate benchmark rate (including any mathematical or other adjustments to the benchmark (if any) incorporated therein), giving due consideration to any evolving or then existing convention for similar syndicated credit facilities denominated in the applicable currency for such alternative benchmarks (any such proposed rate, a “LIBOR Successor Rate”), together with any proposed LIBOR Successor Rate Conforming Changes and any such amendment (a “LIBOR Successor Amendment”), shall become effective at 5:00 p.m. (New York time) on the fifth Business Day after the Administrative Agent shall have posted such proposed LIBOR Successor Amendment to all Lenders and the Loan Parties unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders do not accept such LIBOR Successor Amendment (in which case, the Administrative Agent and the Borrower may propose an alternative LIBOR Successor Amendment).

If no LIBOR Successor Rate has been determined and the circumstances under clause (i) above exist or the Scheduled Unavailability Date has occurred (as applicable), the Administrative Agent will promptly so notify the Borrower and each Lender.  Thereafter, (x) the obligation of the Lenders to make or maintain Eurocurrency Rate Loans in the applicable currency shall be suspended (to the extent of the affected Eurocurrency Rate Loans or Interest Periods), and (y) if the applicable currency is US dollars, then the Eurocurrency Rate component shall no longer be utilized in determining the Base Rate.  Upon receipt of such notice, the applicable Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurocurrency Rate Loans denominated in the applicable currency (to the extent of the affected Eurocurrency Rate Loans or Interest Periods) or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans (subject to the foregoing clause (y)) in the amount specified therein.

Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall such LIBOR Successor Rate be less than zero for purposes of this Agreement.

(aa)    The last sentence in Section 6.10 of the Credit Agreement is hereby amended to read as follows:
