Re:	Mellanox Option Exchange Program — Israeli Tax Matters

Dear Employee:

We wish to update Israeli employees regarding the Israeli tax ruling effort now underway and related to the option exchange offer.

During a telephone call, an ITA official informed us that the pending ruling will provide that the re-pricing event will NOT be a tax event for Mellanox or for any employee.

The ITA official confirmed for us that this was the policy of the ITA, which has been expressed in a previously publicized written ruling.

Thank you.
