This excerpt taken from the SIRI 10-K filed Mar 1, 2007.
(i) Each Award, and each right under any Award, shall be exercisable only by the Participant during the Participant's lifetime, or, if permissible under applicable law, by the Participant's legal guardian or representative.
(ii) No Award may be sold, assigned, alienated, pledged, attached or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution, and any such purported sale, assignment, alienation, pledge, attachment, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate; provided that the designation of a beneficiary shall not constitute a sale, assignment, alienation, pledge, attachment, transfer or encumbrance.
(iii) Notwithstanding the foregoing, the Committee may in the applicable Award Agreement evidencing an Option granted under the Plan or at any time thereafter in an amendment to an Award Agreement provide that Options granted hereunder which are not intended to qualify as Incentive Options may be transferred by the Participant to whom such Option was granted (the Grantee) without consideration, subject to such rules as the Committee may adopt to preserve the purposes of the Plan, to: (1) the Grantee's spouse, children or grandchildren (including adopted and stepchildren and grandchildren) (collectively, the 'Immediate Family'); (2) a trust solely for the benefit of the Grantee and his or her Immediate Family; or (3) a partnership, corporation or limited liability company whose only partners, members or shareholders are the Grantee and his or her Immediate Family; (each transferee described in clauses (1), (2) and (3) above is hereinafter referred to as a Permitted Transferee); provided that the Grantee gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Grantee in writing that such a transfer would comply with the requirements of the Plan and any applicable Award Agreement evidencing the Option.
The terms of any Option transferred in accordance with the immediately preceding sentence shall apply to the Permitted Transferee and any reference in the Plan or in an Award Agreement to an optionee, Grantee or Participant shall be deemed to refer to the Permitted Transferee, except that (a) Permitted Transferees shall not be entitled to transfer any Options, other than by will or the laws of descent and distribution; (b) Permitted Transferees shall not be entitled to exercise any transferred Options unless there shall be in effect a registration statement on an appropriate form covering the Shares to be acquired pursuant to the exercise of such Option if the Committee determines that such a registration statement is necessary or appropriate, (c) the Committee or the Company shall not be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Grantee under the Plan or otherwise and (d) the consequences of termination of the Grantee's employment by, or services to, the Company under the terms of the Plan and the applicable Award Agreement shall continue to be applied with respect to the Grantee, following which the Options shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award Agreement.
