To be eligible to receive a share of the Net Settlement Fund in connection with the Settlement of this Action, you must complete and sign this Proof of Claim and Release Form (“Claim Form”) and submit it, together with the required supporting documentation, either by mail or online.

Failure to submit your Claim Form by the date specified will subject your Claim to rejection and may preclude you from being eligible to receive a payment from the Settlement.

Do not mail or deliver your Claim Form to the Court, Lead Counsel, Defendants’ Counsel, or any of the Parties to the Action.

I. GENERAL INSTRUCTIONS

1. It is important that you completely read the Notice of (I) Proposed Settlement and Plan of Allocation; (II) Settlement Hearing; and (III) Motion for an Award of Attorneys’ Fees and Litigation Expense (the “Settlement Notice”) that accompanies this Claim Form, including the Plan of Allocation of the Net Settlement Fund set forth in the Settlement Notice. The Settlement Notice describes the proposed Settlement, how Class Members are affected by the Settlement, and the manner in which the Net Settlement Fund will be distributed if the Settlement and Plan of Allocation are approved by the Court. The Settlement Notice also contains the definitions of many of the defined terms (which are indicated by initial capital letters) used in this Claim Form. By signing and submitting this Claim Form, you will be certifying that you have read and that you understand the Settlement Notice, including the terms of the releases described therein and provided for herein.

2. By submitting this Claim Form, you will be making a request to share in the proceeds of the Settlement described in the Settlement Notice. If you are not a Class Member (see the definition of the Class on page 6 of the Settlement Notice), do not submit a Claim Form. You may not, directly or indirectly, participate in the Settlement if you are not a Class Member. Thus, if you are excluded from the Class, any Claim Form that you submit, or that may be submitted on your behalf, will not be accepted.

3. Submission of this Claim Form does not guarantee that you will share in the proceeds of the Settlement. The distribution of the Net Settlement Fund will be governed by the Plan of Allocation set forth in the Settlement Notice or by such other plan of allocation as the Court approves.

4. On the Schedule of Transactions in Part III of this Claim Form, provide all of the requested information with respect to your holdings, purchases, acquisitions, and sales of Myriad common stock (including free transfers and deliveries), whether such transactions resulted in a profit or a loss. Failure to report all transaction and holding information during the requested time periods may result in the rejection of your claim.

5. Please note: Only purchases or acquisitions of Myriad common stock from August 9, 2017 until February 6, 2020, inclusive, are potentially eligible under the Settlement and the proposed Plan of Allocation set forth in the Settlement Notice. However, under the “90-day look-back period” (described in the Plan of Allocation), sales of Myriad common stock during the period from February 7, 2020 through and including May 6, 2020 will be used for purposes of calculating Recognized Loss Amounts under the Plan of Allocation. Therefore, in order for the Claims Administrator to be able to balance your claim, the requested purchase information during this period must also be provided.

6. You are required to submit genuine and sufficient documentation for all of your transactions in and holdings of Myriad common stock set forth in the Schedule of Transactions in Part III. Documentation may consist of copies of brokerage confirmation slips or monthly brokerage account statements, or an authorized statement from your broker containing the transactional and holding information found in a broker confirmation slip or account statement. The Parties and the Claims Administrator do not independently have information about your investments in Myriad common stock. IF SUCH DOCUMENTS ARE NOT IN YOUR POSSESSION, PLEASE OBTAIN COPIES OF THE DOCUMENTS OR EQUIVALENT DOCUMENTS FROM YOUR BROKER. FAILURE TO SUPPLY THIS DOCUMENTATION MAY RESULT IN THE REJECTION OF YOUR CLAIM. DO NOT SEND ORIGINAL DOCUMENTS.

7. Please keep a copy of all documents that you send to the Claims Administrator. Also, do not highlight any portion of the Claim Form or any supporting documents.

8. Use Part I of this Claim Form entitled “CLAIMANT INFORMATION” to identify the beneficial owner(s) of Myriad common stock. The complete name(s) of the beneficial owner(s) must be entered. If you held the Myriad common stock in your own name, you were the beneficial owner as well as the record owner. If, however, your shares of Myriad common stock were registered in the name of a third party, such as a nominee or brokerage firm, you were the beneficial owner of these shares, but the third party was the record owner. The beneficial owner, not the record owner, must sign this Claim Form to be eligible to participate in the Settlement. If there were joint beneficial owners each must sign this Claim Form and their names must appear as “Claimants” in Part I of this Claim Form.

9. One Claim should be submitted for each separate legal entity or separately managed account. Separate Claim Forms should be submitted for each separate legal entity (e.g., an individual should not combine his or her IRA transactions with transactions made solely in the individual’s name). Generally, a single Claim Form should be submitted on behalf of one legal entity including all holdings and transactions made by that entity on one Claim Form. However, if a single person or legal entity had multiple accounts that were separately managed, separate Claims may be submitted for each such account. The Claims Administrator reserves the right to request information on all the holdings and transactions in Myriad common stock made on behalf of a single beneficial owner.

10. Agents, executors, administrators, guardians, and trustees must complete and sign the Claim Form on behalf of persons represented by them, and they must:

11. By submitting a signed Claim Form, you will be swearing that you:

12. The proceeds of the proposed Settlement, if approved, may include shares of Myriad common stock (the “Settlement Shares”). The Settlement Shares, less any Settlement Shares awarded to Plaintiff’s Counsel as attorneys’ fees, are referred to as the “Class Settlement Shares.” If Settlement Shares are issued, Lead Counsel has the right to decide, in its sole discretion, whether to: (i) sell all or any portion of the Class Settlement Shares and distribute the net cash proceeds from the sale of the shares to Claimants who submit claims that are approved for payment by the Court (“Authorized Claimants”) or (ii) distribute the Class Settlement Shares to Authorized Claimants. If distributed, the Class Settlement Shares will be posted electronically to the accounts of Authorized Claimants on the Direct Registration System (“DRS”) maintained by Myriad’s transfer agent. A supplemental request for information required to electronically post the Class Settlement Shares to an account on the DRS will be sent to Claimants if shares are to be distributed. Failure to provide the information requested may lead to forfeiture of the Class Settlement Shares to which you might otherwise be eligible.

13. By submitting a signed Claim Form, you will be swearing to the truth of the statements contained therein and the genuineness of the documents attached thereto, subject to penalties of perjury under the laws of the United States of America. The making of false statements, or the submission of forged or fraudulent documentation, will result in the rejection of your claim and may subject you to civil liability or criminal prosecution.

14. Payments to eligible Authorized Claimants will be made only if the Court approves the Settlement, after any appeals are resolved, and after the completion of all claims processing.

15. PLEASE NOTE: As set forth in the Plan of Allocation, each Authorized Claimant shall receive his, her, or its pro rata share of the Net Settlement Fund. No cash payments for less than $10.00 will be made. In the event of a distribution of Settlement Shares, no fractional Settlement Shares will be issued.
