NEWMARKET CORPORATION

Restricted Stock Award Agreement

THIS AGREEMENT dated as of the 28th day of October 2014, between NEWMARKET
CORPORATION, a Virginia corporation (the “Corporation”), and <<Name>>
(“Participant”), is made pursuant and subject to the provisions of the NewMarket
Corporation 2014 Stock Incentive Plan (the “Plan”). All terms used herein that
are defined in the Plan have the same meaning given them in the Plan.

1.    Award of Stock. Pursuant to the Plan, the Corporation, on November 14,
2014 (the “Award Date”), grants to Participant an award of <<# shares>> of
Common Stock (the “Restricted Stock”). This award of Restricted Stock is subject
to the terms and conditions of the Plan and subject further to the terms and
conditions set forth herein.

2.    Restrictions. Except as provided in this Agreement, the Restricted Stock
is nontransferable and is subject to a substantial risk of forfeiture.

3.    Vesting. Participant’s interest in the Restricted Stock shall be
transferable and nonforfeitable (“Vested”) on the fifth anniversary of the Award
Date (the “Vesting Date”). In addition, the Restricted Stock shall become Vested
as of the date the Participant dies or becomes totally and permanently disabled
(within the meaning of Code section 22(c)(3)) and the date of Participant’s
death or disability shall be considered the Vesting Date for purposes of
Sections 4 and 5 below.

4.    Forfeiture. All shares of Restricted Stock that are not then Vested shall
be forfeited if (i) Participant’s employment with the Corporation or an
Affiliate terminates prior to the date such shares have become Vested pursuant
to Section 3 or (ii) Participant is no longer serving as an executive officer of
the Corporation or an Affiliate on the Vesting Date.

5.    Shareholder Rights. Participant will have all the rights of a shareholder
of the Corporation with respect to the Restricted Stock, including the right to
receive dividends on and to vote the Restricted Stock; provided, however, that
(i) Participant may not sell, transfer, pledge, exchange, hypothecate or
otherwise dispose of the Restricted Stock, (ii) if the Restricted Stock is
evidenced by a certificate, the Corporation shall retain custody of such
certificate as provided in Section 6, and (iii) Participant will deliver a stock
power in accordance with Section 7.

6.    Certificates.    At the option of the Corporation, the Restricted Stock
shall be evidenced by an entry on the registry books of the Corporation or by a
certificate issued by the Corporation. Participant may not receive or take
possession of any shares of Restricted Stock through book-entry accounts held
by, or in the name of, Participant so long as the Restricted Stock is not
Vested. If the Restricted Stock is evidenced by a certificate, custody of such
certificate evidencing the Restricted Stock shall be retained by the Corporation
so long as the Restricted Stock is not Vested. Any book entries and certificates
evidencing the Restricted Stock shall carry or be endorsed with a legend
restricting the transferability of shares set forth in this Agreement. The
Corporation shall release the restrictions on the book entry evidencing the
Restricted Stock or deliver to Participant the stock certificates evidencing the
Common Stock as soon as practicable after the Restricted Stock becomes Vested.

7.    Stock Power.    Participant shall deliver to the Corporation a stock
power, endorsed in blank, with respect to the Restricted Stock. The Corporation
shall use the stock power to cancel any shares of Restricted Stock that do not
become Vested. The Corporation shall return the stock power to Participant with
respect to any shares of Restricted Stock that become Vested.

--------------------------------------------------------------------------------

8.    Fractional Shares. Fractional shares of Common Stock shall not be issuable
hereunder, and when any provision hereof or the Plan may entitle Participant to
a fractional share, such fraction shall be disregarded.

9.    Taxes. The Corporation shall retain and withhold from the award of
Restricted Stock, the amount of taxes required by any government to be withheld
to satisfy minimum statutory withholding obligations with respect to such award.
The Corporation shall retain and withhold a number of shares of the Vested
Restricted Stock having a Fair Market Value as of the date the shares become
Vested that is not less than the amount of such taxes, and the Corporation shall
cancel in whole or in part any such shares so withheld, in order to satisfy the
Corporation’s withholding obligations.

10.    No Right to Continued Employment. This Agreement does not confer upon
Participant any right with respect to continued employment by the Corporation,
nor shall it interfere in any way with the right of the Corporation to terminate
Participant’s employment at any time.

11.    Governing Law. This Agreement shall be governed by the laws of the
Commonwealth of Virginia.

12.    Conflicts. In the event of any conflict between the provisions of the
Plan and the provisions of this Agreement, the provisions of the Plan shall
govern.

13.    Participant Bound by Plan. Participant hereby acknowledges receipt of a
copy of the Plan and agrees to be bound by all the terms and provisions thereof.

14.    Binding Effect. Subject to the limitations stated above and in the Plan,
this Agreement shall be binding upon and inure to the benefit of the legatees,
distributees, and personal representatives of the Participant and the successors
of the Corporation.
