Explanation of Responses:

1. Disposed of pursuant to the Agreement and Plan of Merger, by and among DiaSorin S.p.A., Diagonal Subsidiary Inc. and Luminex Corporation (the "Issuer"), dated April 11, 2021 (the "Merger Agreement"), whereby each outstanding share of the Issuer's common stock was cancelled at the effective time (the "Effective Time") of the merger (the "Merger") and converted into the right to receive a cash payment of $37.00 per share.

2. This amount includes 291 shares obtained under the Luminex Corporation Employee Stock Purchase Plan on May 31, 2021.

3. Disposed of pursuant to the Merger Agreement, whereby unvested shares of restricted stock which were outstanding as of immediately prior to the Effective Time fully vested and became unrestricted common stock, and each such share of common stock that was outstanding immediately prior to the Effective Time was canceled at the Effective Time, in exchange for cash payments in the amount of $37.00 per share (without interest and subject to deduction for any required withholding taxes).

4. Disposed of pursuant to the Merger Agreement, whereby each stock option outstanding as of immediately prior to the Effective Time fully vested and was cancelled at the Effective Time and converted into the right to receive a total amount in cash, equal to the product of (x) the excess, if any, of $37.00 over the exercise price per share of each stock option (without interest and subject to deduction for any required withholding taxes) and (y) the number of shares underlying such stock option. If the amount that could have been obtained upon the exercise of the stock option pursuant to the foregoing is equal to or less than zero, then the option was terminated without payment.
