maintained by MyoKardia’s transfer agent), any tendered but unpurchased Shares (including as a result of any necessary proration) will be credited to the appropriate account maintained by the tendering stockholder at DTC (or by MyoKardia’s transfer agent). In each case, Shares will be returned or credited without expense to the stockholder.
5. Signatures on Letter of Transmittal; Stock Powers and Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the certificates without alteration or any change whatsoever.
If any of the Shares tendered hereby are held of record by two or more persons, all such persons must sign this Letter of Transmittal.
If any of the Shares tendered hereby are registered in different names on different certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates.
If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or Shares not tendered or not accepted for payment are to be returned, in the name of any person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an Eligible Institution.
If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates for such Shares. Signature(s) on any such certificates or stock powers must be guaranteed by an Eligible Institution.
If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to Purchaser of the authority of such person so to act must be submitted, or in lieu of evidence, a Guarantee of Signature (see Instruction 1).
6. Stock Transfer Taxes. Purchaser will pay any stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or Shares not tendered or not accepted for payment are to be returned in the name of, any person other than the registered holder(s), or if a transfer tax is imposed for any reason other than the sale or transfer of Shares to Purchaser pursuant to the Offer, then the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person or otherwise) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted herewith.
7. Special Payment and Delivery Instructions. If the check for the purchase price of any Shares purchased is to be issued in the name of a person other than the person(s) signing this Letter of Transmittal or if the check is to be mailed to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed.
8. Backup Withholding. Under the U.S. federal income tax laws, unless certain certification requirements are met, the Depositary generally will be required to withhold at the applicable backup withholding rate (currently 24%) from any payments made to a stockholder pursuant to the Offer. In order to avoid such backup withholding, each tendering stockholder, and, if applicable, each other payee, must provide the Depositary with such stockholder’s or payee’s correct taxpayer identification number and certify that such stockholder or payee is not subject to such backup withholding by completing the IRS Form W-9 enclosed herein. In general, if a stockholder or payee is an individual, the taxpayer identification number is the social security number of such individual. If the stockholder or payee does not provide the Depositary with its correct taxpayer identification number, the stockholder or payee may be subject to a penalty imposed by the Internal Revenue Service. Certain stockholders or payees (including, generally, domestic corporations and foreign stockholders) are not subject to these backup withholding and reporting requirements. In order to satisfy the Depositary that a foreign stockholder is exempt, such stockholder or payee must submit to the Depositary a properly completed IRS Form W-8, signed under penalties of perjury, attesting to that stockholder’s foreign status. Such IRS Form W-8 can be obtained from the Depositary or the Internal Revenue
