Permitted Transferees The rights of a Holder hereunder may be assigned (but only with all related obligations as set forth below) in connection with a Transfer of Registrable Securities to a Permitted Transferee of that Holder. Without prejudice to any other or similar conditions imposed hereunder with respect to any such Transfer, no assignment permitted under the terms of this Section 4.4 will be effective unless the Permitted Transferee to which the assignment is being made, if not a Holder, has delivered to the Company a written acknowledgment and agreement in form and substance reasonably satisfactory to the Company that the Permitted Transferee will be bound by, and will be a party to, this Agreement. A Permitted Transferee to whom rights are transferred pursuant to this Section 4.4 may not again transfer those rights to any other Permitted Transferee, other than as provided in this Section 4.4.
