 ARTICLE II 
 PURPOSES 
  
 The Plan is intended to assist the Company and Related Entities in recruiting and retaining individuals with ability and
initiative by enabling such persons to participate in the future success of the Company and the Related Entities and to associate their interests with those of the Company and its shareholders. The Plan is intended to permit the grant of both
Options qualifying under Code section 422 (“incentive stock options”) and Options not so qualifying, and the grant of SARs, Stock Awards or Incentive Awards. No Option that is intended to be an incentive stock option shall be invalid for
failure to qualify as an incentive stock option. The proceeds received by the Company from the sale of Common Stock pursuant to this Plan shall be used for general corporate purposes.

 ARTICLE III 
 ADMINISTRATION 
  
 The Plan shall be administered by the Administrator. The Administrator shall have authority to grant Stock Awards, Incentive
Awards, Options and SARs upon such terms (not inconsistent with the provisions of this Plan) as the Administrator may consider appropriate. Such terms may include conditions (in addition to those contained in this Plan) on the exercisability of all
or any part of an Option or SAR or on the transferability or forfeitability of a Stock Award or an Incentive Award, including by way of example and not of limitation, requirements that the Participant complete a specified period of employment or
service with the Company or a Related Entity, requirements that the Company achieve a specified level of financial performance or that the Company achieve a specified level of financial return. Notwithstanding any such conditions, the Administrator
may, in its discretion, accelerate the time at which any Option or SAR may be exercised, the time at which a Stock Award may become transferable or nonforfeitable or both, or the time at which an Incentive Award may be settled or defer the receipt
of Common Stock issuable upon the exercise of the Option or permit the deferral of a Stock Award. In addition, the Administrator shall have complete authority to interpret all provisions of this Plan; to prescribe the form of Agreements; to adopt,
amend, and rescind rules and regulations pertaining to the administration of the Plan; and to make all other determinations necessary or advisable for the administration of this Plan. The express grant in the Plan of any specific power to the
Administrator shall not be construed as limiting any power or authority of the Administrator. Any decision made, or action taken, by the Administrator in connection with the administration of this Plan shall be final and conclusive. Neither the
Administrator nor any member of the Committee shall be liable for any act done in good faith with respect to this Plan or any Agreement, Option, SAR, Stock Award or Incentive Award. All expenses of administering this Plan shall be borne by the
Company, a Related Entity or a combination thereof. 
  
 The
Committee, in its discretion, may delegate to one or more officers of the Company all or part of the Committee’s authority and duties with respect to grants and awards to individuals who are not subject to the reporting and other provisions of
Section 16 of the Exchange Act. The Committee may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Committee’s delegate or delegates that were consistent with the terms of the
Plan.

 5.02 Aggregate Limit 
  
 The maximum aggregate number of shares of Common Stock that may be issued

than its exercise or the exercise of a related SAR, the number of shares of Common Stock allocated to the Option or portion thereof may be reallocated to other Options, SARs, Incentive Awards and Stock Awards to be granted under this Plan. If an SAR
is terminated, in whole or in part, for any reason other than its exercise or the exercise of a related Option, the number of shares of Common Stock allocated to the SAR or portion thereof may be reallocated to other Options, SARs, Incentive Awards
and Stock Awards to be granted under this Plan. If a Stock Award is forfeited or terminated, in whole or in part for any reason, the number of shares of Common Stock allocated to the Stock Award or portion thereof may be reallocated to other

 OPTIONS 
  
 6.01 Award 
  
 In accordance with the provisions of Article IV, the Administrator will designate each individual to whom an Option is to be granted and will specify the
number of shares of Common Stock covered by each such award; provided, however that no Participant may be granted Options in any calendar year covering more than 200,000 shares of Common Stock. 
  
 6.02 Option Price 
  
 The price per share for Common Stock purchased on the exercise of an Option
shall be determined by the Administrator on the date of grant, but shall not be less than the Fair Market Value on the date the Option is granted. Except for an adjustment authorized under Article X, the Option price may not be reduced (by amendment
or cancellation of the Option or otherwise) after the date of grant. 
  
 6.03
Maximum Option Period 
  
 The maximum period in
which an Option may be exercised shall be ten years from the date such Option was granted. The terms of any Option may provide that it has a term that is less than such maximum period. 
  
 6.04 Nontransferability 
  
 Except as provided in Section 6.05, each Option granted under this Plan shall be nontransferable except by will or by the laws of descent and
distribution. In the event of any transfer of an Option (by the Participant or his transferee), the Option and any SAR that relates to such Option must be transferred to the same person or persons or entity or entities. Except as provided in Section
6.05, during the lifetime of the Participant to whom the Option is granted, the Option may be exercised only by the Participant. No right or interest of a Participant in any Option shall be liable for, or subject to, any lien, obligation, or
liability of such Participant. 
  
 6.05 Transferable Options

  
 Section 6.04 to the contrary notwithstanding, if the
Agreement provides, an Option that is not an incentive stock option may be transferred by a Participant to the Participant’s children, grandchildren, spouse, one or more trusts for the benefit of such family members or a partnership in which
such family members are the only partners, on such terms and conditions as may be permitted under Securities Exchange Commission Rule 16b-3 as in effect from time to time. The holder of an Option transferred pursuant to this section shall be bound
by the same terms and conditions that governed the Option during the period that it was held by the Participant; provided, however, that such transferee may not transfer the Option except by will or the laws of descent and distribution. In the event
of any transfer of an Option (by the Participant or his transferee), the Option and any SAR that relates to such Option must be transferred to the same person or persons or entity or entities.

 6.06 Employee Status 
  
 For purposes of
determining the applicability of Code section 422 (relating to incentive stock options), or if the terms of any Option provide that it may be exercised only during employment or continued service or within a specified period of time after
termination of employment or service, the Administrator may decide to what extent leaves of absence for governmental or military service, illness, temporary disability, or other reasons shall not be deemed interruptions of continuous employment or
service. 
  
 6.07 Exercise 
  
 Subject to the provisions of this Plan and the applicable Agreement, an
Option may be exercised in whole at any time or in part from time to time at such times and in compliance with such requirements as the Administrator shall determine; provided, however, that incentive stock options (granted under the Plan and all
plans of the Company and its Related Entities) may not be first exercisable in a calendar year for stock having a Fair Market Value (determined as of the date an Option is granted) exceeding the limit prescribed by Code section 422(d). An Option
granted under this Plan may be exercised with respect to any number of whole shares less than the full number for which the Option could be exercised. A partial exercise of an Option shall not affect the right to exercise the Option from time to
time in accordance with this Plan and the applicable Agreement with respect to the remaining shares subject to the Option. The exercise of an Option shall result in the termination of any SAR to the extent of the number of shares with respect to
which the Option is exercised. 
  
 6.08 Payment 
  
 Unless otherwise provided by the Agreement, payment of the Option price
shall be made in cash or a cash equivalent acceptable to the Administrator. Subject to rules established by the Administrator, payment of all or part of the Option price may be made with shares of Common Stock which have been owned by the
Participant for at least six months and which have not been used for another Option exercise during the prior six months. If Common Stock is used to pay all or part of the Option price, the sum of the cash and cash equivalent and the Fair Market
Value (determined as of the day preceding the date of exercise) of the shares surrendered must not be less than the Option price of the shares for which the Option is being exercised. 
  
 6.09 Change in Control 
  
 Section 6.07 to the contrary notwithstanding, each outstanding Option shall be fully exercisable on and after a Control Change Date in accordance with the
terms of the applicable Agreement. 
  
 6.10 Shareholder Rights

  
 No Participant shall have any rights as a shareholder with
respect to shares subject to his Option until the date of exercise of such Option.

 2004 Incentive Compensation and Stock Plan 
  
 6.11 Disposition of Stock 
  
 A
Participant shall notify the Company of any sale or other disposition of Common Stock acquired pursuant to an Option that was an incentive stock option if such sale or disposition occurs (a) within two years of the grant of an Option or (b) within
one year of the issuance of the Common Stock to the Participant. Such notice shall be in writing and directed to the Secretary of the Company.

 ARTICLE VII 
 SARS 
  
 7.01 Award 
  
 In accordance with the provisions of Article IV, the Administrator will designate each individual to whom SARs are to be granted and will specify the
number of shares covered by each such award; provided, however, no Participant may be granted SARS in any calendar year covering more than 200,000 shares of Common Stock. For purposes of the foregoing limit, an Option and SAR shall be treated as a
single award. In addition, no Participant may be granted SARs (under all incentive stock option plans of the Company and its Affiliates) that are related to incentive stock options which are first exercisable in any calendar year for stock having an
aggregate Fair Market Value (determined as of the date the related Option is granted) that exceeds the limit prescribed by Code section 422(d). 
  
 7.02 Maximum SAR Period 
  
 The period in which an SAR may be exercised shall not be longer than the term of the related Option. The terms of any SAR may provide that it has a term
that is less than such maximum period. 
  
 7.03 Nontransferability

  
 Except as provided in Section 7.04, each SAR granted under
this Plan shall be nontransferable except by will or by the laws of descent and distribution. In the event of any such transfer, an SAR and the related Option must be transferred to the same person or persons or entity or entities. Except as
provided in Section 7.04, during the lifetime of the Participant to whom the SAR is granted, the SAR may be exercised only by the Participant. No right or interest of a Participant in any SAR shall be liable for, or subject to, any lien, obligation,
or liability of such Participant. 
  
 7.04 Transferable SARs

  
 Section 7.03 to the contrary notwithstanding, if the
Agreement provides, an SAR, other than an SAR that is related to an incentive stock option, may be transferred by a Participant to the Participant’s children, grandchildren, spouse, one or more trusts for the benefit of such family members or a
partnership in which such family members are the only partners, on such terms and conditions as may be permitted under Securities Exchange Commission Rule 16b-3 as in effect from time to time. The holder of an SAR transferred pursuant to this
section shall be bound by the same terms and conditions that governed the SAR during the period that it was held by the Participant; provided, however, that such transferee may not transfer the SAR except by will or the laws of descent and
distribution. In the event of any transfer of an SAR (by the Participant or his transferee), the SAR and the related Option must be transferred to the same person or persons or entity or entities. 
  

 12 








 NewMarket Corporation 
 2004 Incentive Compensation and Stock Plan 
  
 7.05 Exercise 
  
 Subject to the
provisions of this Plan and the applicable Agreement, an SAR may be exercised in whole at any time or in part from time to time at such times and in compliance with such requirements as the Administrator shall determine; provided, however, that an
SAR that is related to an incentive stock option may be exercised only to the extent that the related Option is exercisable and only when the Fair Market Value exceeds the option price of the related Option. An SAR granted under this Plan may be
exercised with respect to any number of whole shares less than the full number for which the SAR could be exercised. A partial exercise of an SAR shall not affect the right to exercise the SAR from time to time in accordance with this Plan and the
applicable Agreement with respect to the remaining shares subject to the SAR. The exercise of an SAR shall result in the termination of the related Option to the extent of the number of shares with respect to which the SAR is exercised. 

 
 7.06 Change in Control 
  
 Section 7.05 to the contrary notwithstanding, each outstanding SAR shall be
fully exercisable on and after a Control Change Date in accordance with the applicable Agreement. 
  
 7.07 Employee Status 
  
 If the terms of any SAR provide that it may be exercised only during employment or continued service or within a specified period of time after termination of employment or service, the Administrator may decide to what extent leaves of
absence for governmental or military service, illness, temporary disability or other reasons shall not be deemed interruptions of continuous employment or service.

 ARTICLE VIII 
 STOCK AWARDS 
  
 8.01 Award 
  
 In accordance with the provisions of Article IV, the Administrator will designate each individual to whom a Stock Award is to be made and will specify the
number of shares of Common Stock covered by each such award; provided, however, that no Participant may receive Stock Awards in any calendar year for more than 200,000 shares of Common Stock and provided, further that the issuance of a Stock Award
in settlement of a Stock Award shall not be subject to the foregoing share limitation. 
  
 8.02 Vesting 
  
 The Administrator, on the
date of the award, may prescribe that a Participant’s rights in a Stock Award shall be forfeitable or otherwise restricted for a period of time or subject to such conditions as may be set forth in the Agreement. By way of example and not of
limitation, the restrictions may postpone transferability of the shares or may provide that the shares will be forfeited if the Participant separates from the service of the Company and its Related Entities before the expiration of a stated period
or if the Company, a Related Entity, the Company and its Related Entities or the Participant fails to achieve stated performance objectives, including performance objectives stated with reference to Performance Criteria. If a Stock Award is not
immediately vested and transferable, the period that the shares are restricted shall be at least three years; provided, however, that the period that the shares are restricted shall be at least one year if the transferability, vesting or both is
subject to the satisfaction of performance objectives stated with reference to Performance Criteria. The Administrator, in its discretion, may waive the requirements for vesting or transferability for all or part of the shares subject to a Stock
Award in connection with a Participant’s termination of employment or service. 
  
 8.03 Employee Status 
  
 If the terms of
any Stock Award provide that shares may become transferable and nonforfeitable thereunder only after completion of a specified period of employment or service, the Administrator may decide in each case to what extent leaves of absence for
governmental or military service, illness, temporary disability, or other reasons shall not be deemed interruptions of continuous employment or service. 
  
 8.04 Change in Control 
  
 Sections 8.02 and 8.03 to the contrary notwithstanding, each outstanding Stock Award shall be transferable and nonforfeitable on and after a Control
Change Date in accordance with the applicable Agreement. 
  
 8.05
Shareholder Rights 
  
 Prior to their forfeiture
(in accordance with the applicable Agreement and while the shares of Common Stock granted pursuant to the Stock Award may be forfeited or are

Compensation and Stock Plan 
  
 nontransferable), a Participant will have all the
rights of a shareholder with respect to a Stock Award, including the right to receive dividends and vote the shares; provided, however, that during such period (a) a Participant may not sell, transfer, pledge, exchange, hypothecate, or otherwise
dispose of shares of Common Stock granted pursuant to a Stock Award, (b) the Company shall retain custody of the certificates evidencing shares of Common Stock granted pursuant to a Stock Award, and (c) the Participant will deliver to the Company a
stock power, endorsed in blank, with respect to each Stock Award. The limitations set forth in the preceding sentence shall not apply after the shares of Common Stock granted under the Stock Award are transferable and are no longer forfeitable.

 ARTICLE IX 
 INCENTIVE AWARDS 
  
 9.01 Award 
  
 The Administrator will designate Participants to whom Incentive Awards are made. All Incentive Awards shall be finally determined exclusively by the

 9.02 Terms and Conditions 
  
 The Administrator, at the time an Incentive Award is made, shall specify the
terms and conditions which govern the award. Such terms and conditions shall prescribe that the Incentive Award shall be earned only upon, and to the extent that, performance objectives are satisfied during a performance period of at least one year
after the grant of the Incentive Award. By way of example and not of limitation, the performance objectives may provide that the Incentive Award will be earned only if the Company, a Related Entity or the Company and its Related Entities achieve
stated objectives, including objectives stated with reference to Performance Criteria. The Administrator, at the time an Incentive Award is made, shall also specify when amounts shall be payable under the Incentive Award and whether amounts shall be
payable in the event of the Participant’s death, disability, or retirement. 
  
 9.03 Nontransferability 
  
 Except as
provided in Section 9.04, Incentive Awards granted under this Plan shall be nontransferable except by will or by the laws of descent and distribution. No right or interest of a Participant in an Incentive Award shall be liable for, or subject to,
any lien, obligation, or liability of such Participant. 
  
 9.04
Transferable Incentive Awards 
  
 Section 9.03 to
the contrary notwithstanding, if provided in an Agreement, an Incentive Award may be transferred by a Participant to the Participant’s children, grandchildren, spouse, one or more trusts for the benefit of such family members or to a
partnership in which such family members are the only partners, on such terms and conditions as may be permitted by Rule 16b-3 under the Exchange Act as in effect from time to time. The holder of an Incentive Award transferred pursuant to this
Section shall be bound by the same terms and conditions that governed the Incentive Award during the period that it was held by the Participant; provided, however, that such transferee may not transfer the Incentive Award except by will or the laws
of descent and distribution. 
  
 9.05 Employee Status 
  
 If the terms of an Incentive Award provide that a payment will be made
thereunder only if the Participant completes a stated period of employment or service, the Administrator may

with the applicable Agreement.

 No Participant shall, as a result of receiving an Incentive
Award, have any rights as a shareholder of the Company or any Related Entity on account of such award until, and except to the extent that, the Incentive Award is earned and settled in shares of Common Stock.
