Notes Due 2016 </B></FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">RICHMOND, VA, January&nbsp;4, 2011 &#151; NewMarket Corporation (NYSE: NEU) announced today that it is soliciting consents
from holders of its outstanding 7.125% Senior Notes due 2016 (the &#147;Securities&#148;) to approve a proposed amendment to the indenture relating to the Securities. The proposed amendment, if adopted, would modify the formula for calculating
NewMarket&#146;s capacity to make certain restricted payments, which is set forth in Section&nbsp;4.07(a) of the indenture, and would provide NewMarket with additional flexibility to make restricted payments, including, without limitation,
repurchases of its outstanding shares of common stock. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Adoption of the proposed amendment requires the consent of holders of at least a
majority in principal amount of the outstanding Securities voting as a single class. As of 5:00 p.m., New York City time, on December&nbsp;31, 2010 (the &#147;Record Time&#148;), which NewMarket has fixed as the record time for determining the
holders entitled to give consents, the aggregate principal amount of Securities issued and outstanding was $150,000,000. The consent solicitation expires at 5:00 p.m., New York City time, on January&nbsp;18, 2011, unless NewMarket extends it (the
&#147;Expiration Date&#148;). </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Assuming satisfaction or waiver of all of the conditions to the consent solicitation, and acceptance by
NewMarket of the consents and effectiveness of the supplemental indenture, NewMarket will pay the consent fee of $15.00 per $1,000 principal amount of Securities held by a holder with respect to which a valid consent has been delivered and not
validly revoked prior to the Expiration Date. The consent fee will be payable only to holders of the Securities as of the record time who validly deliver consents and do not validly revoke such consents prior to the Expiration Date or their proper
designees. No consent fee will be payable with respect to consents received after the Expiration Date. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Consents that have been validly
delivered may be validly revoked at any time prior to the earlier of the time that the supplemental indenture setting forth the proposed amendment to the indenture becomes effective and the Expiration Date, but not thereafter. If the requisite
consents to the proposed amendment are received and the supplemental indenture becomes effective and operative, the amendment will be binding on all holders of the Securities, including holders that do not deliver a valid and unrevoked consent.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">This press release is not a solicitation of consents with respect to the Securities. The consent solicitation is being made solely by the
