**PART II**

#### Distribution Schedule

#### Instructions: To be completed by the Client.
The following constitutes the undersigned's plan to distribute the Shares.

If on any trading day, the closing stock price of the Issuer meets the "Threshold Trigger" of an applicable Tranche as set forth in the Distribution Schedule Table Part IV - Exhibit B of this Plan, MSSB shall promptly provide notice to Aduro Advisors ("Aduro"). Such notice shall include (1) the applicable "Threshold Trigger" that has been achieved and (2) the 30-day average trading volume of the Issuer's common stock (the "MSSB Notice"). Upon receipt of MSSB Notice, Aduro shall promptly calculate the pro rata distribution of Shares to be distributed to the partners of the Client, and promptly notify the Client and MSSB of the same (the "Aduro Notice"). In the event the number of Shares to be distributed to applicable partners, as calculated by Aduro, results in fractional shares, the number of shares shall be rounded down to the nearest whole share. Upon receipt of the Aduro Notice, (1) the Client shall promptly notify the transfer agent of the Issuer in substantially the form set forth in Part IV - Exhibit C hereto, and (2) the transfer agent, in coordination with MSSB, shall make a distribution of Shares to each applicable partner as set forth in the Aduro Notice (a "Distribution").

A Distribution shall be made for each trading day on which the closing stock price meets the applicable "Threshold Trigger" until the cumulative number of shares distributed for an applicable Tranche equals the "Total number of shares to distribute", as set forth on Exhibit B, for such tranche; provided, however, that the final Distribution within each applicable Tranche shall be reduced so that the cumulative number of shares distributed in each applicable Tranche does not exceed the amount of shares included in the "Total number of shares to be distributed" column for such Tranche. Once the cumulative number of shares distributed for an applicable Tranche meets the corresponding "Total number of shares to distribute" amount, the transfer agent, in coordination with MSSB, shall make a Distribution for each trading day in which the closing stock price meets the "Threshold Trigger" and the "Total number of shares to distribute" for the subsequent tranche, until the shares for each tranche have been fully distributed.

Prior to Distribution Start Date, Client will send to MSSB by electronic mail to the applicable persons indicated in Part I – Account and Plan Information, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A letter of authorization to deliver the underlying shares to limited partners and general partners of Client;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A schedule of limited partners and general partners of Client (the "Partnership Schedule");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A distribution representation letter that lists affiliates and non-affiliates (Part IV - Exhibit A), as known by the Client and as of the date of the Distribution Plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All documentation required to transfer Shares into book entry, including, but not limited to, stock powers.

&nbsp;&nbsp;&nbsp;&nbsp;<br>

Client shall adjust the Share amounts and the prices referenced above to take into account any stock split, reverse stock split or stock dividend with respect to the Shares or any change in capitalization with respect to the Issuer that occurs while the Distribution Plan is in effect, and Client shall reflect such adjustments in a timely notice provided to MSSB.

#### PART III

#### Distribution Plan Disclosures and Representations
**A. General Representations**.

I understand that this Distribution Plan is patterned on certain provisions of SEC Rule 10b5-1 of the Securities and Exchange Commission (the "**Rules**"). In summary, under the Rules, a person executing pre-planned **purchases or sales** pursuant to a written plan established in good faith at a time when that person was unaware of material nonpublic information has an affirmative defense against allegations of insider trading with respect to such **purchases or sales**. **The undersigned understands that this Distribution Plan covers distributions and does not contemplate any purchases or sales by the Client.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The undersigned hereby represents that, as of the date of my signature below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The undersigned is not in possession, and is not aware, of any material nonpublic information about the securities which are the subject of this Distribution Plan or the Issuer of such securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The undersigned is entering into this Distribution Plan in good faith and not as part of a plan or scheme to evade any law, including, without limitation, the federal securities laws or any law governing insider trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. **The undersigned understands and agrees that (i) MSSB makes no representation that this Distribution Plan complies with, and/or provides an affirmative defense against allegations of insider trading pursuant to, SEC Rule 10b5-1, and (ii) the undersigned has consulted with the undersigned's own advisors as to the legal, tax, financial and other aspects of this Distribution Plan, including its compliance with SEC Rule 10b5-1**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. The undersigned owns the securities which are the subject of this Distribution Plan free and clear and acknowledges and confirms that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Neither the undersigned nor the securities subject to this Distribution Plan are subject to any pledges, liens, security interests or other impediments to transfer, nor is there any contractual restriction or litigation, arbitration or other proceeding pending, or to the undersigned's knowledge threatened, that would prevent or interfere with the distribution of Shares under this Distribution Plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To the best of the undersigned's knowledge, the execution and delivery of this Distribution Plan by the undersigned and the distribution contemplated by this Distribution Plan will not contravene applicable law or any agreement or other instrument binding on the undersigned or any of the undersigned's affiliates or any judgment, order or decree of any governmental body, agency or court having jurisdiction over the undersigned or the undersigned's affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. While this Distribution Plan is in effect, the undersign will not enter into any corresponding or hedging transaction or position with respect to the securities that are the subject of this Distribution Plan (including, without limitation, with respect to any securities convertible or exchangeable into common stock of the Issuer) and, unless this Distribution Plan is modified or terminated in accordance with the terms hereof, the undersigned agrees not to alter or deviate from the terms of this Distribution Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. The undersigned agrees not to, directly or indirectly, attempt to exercise any influence over how, when or whether to effect any distribution of Shares pursuant to this Distribution Plan (other than by providing the notice to MSSB further described in Part II. above); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g. The undesigned represents that, to the best of my knowledge, this Distribution Plan conforms with the trading policies of the Issuer currently in place as of the date of this Distribution Plan and only to the extent applicable to the undersigned.

B. Modification, Suspension and Termination.
