NEWMARKET CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



|1. | Financial Statement Presentation
|-- | --------------------------------

In the opinion of
management, the accompanying consolidated financial statements of NewMarket Corporation and its subsidiaries contain all necessary adjustments for the fair presentation of, in all material respects, our consolidated financial position as of
March 31, 2009, as well as our consolidated results of operations and our consolidated cash flows for the three months ended March 31, 2009 and March 31, 2008. All adjustments are of a normal, recurring nature, unless otherwise
disclosed. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the NewMarket Corporation Annual Report on Form 10-K for the fiscal year ended December 31, 2008 (2008
Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the three month period ended March 31, 2009 are not necessarily indicative of the results to be expected for the full year ending
December 31, 2009. The December 31, 2008 consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of
America.

Unless the context otherwise requires, all references to we, us, our, the Company
and NewMarket are to NewMarket Corporation and its consolidated subsidiaries.

At both March 31, 2009 and December 31,
2008, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents transactions that have not cleared the bank accounts at the end of the reporting period. There are no agreements with the same banks to offset the
presented balance. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods.

Cash dividends
totaling 20 cents per share for both the three months ended March 31, 2009 and March 31, 2008 were declared and paid as shown in the table below.



|     |  |                   |  |               |  |

|2008 |  | February 28, 2008 |  | April 1, 2008 |  | 20 cents       

During the three months ended March 31, 2009, we had noncash investing activity of $9.1
million related to capital expenditures incurred, but not paid, for the construction of the office building by Foundry Park I, LLC (Foundry Park I), as well as other capital projects of Afton Chemical Corporation (Afton).

|5. | Earnings Per Share
|-- | ------------------

Basic and diluted earnings per
share are calculated as shown in the table below. Options are not included in the computation of diluted earnings per share when the option exercise price exceeds the average market price of the underlying common share, as the impact on earnings per
share would be anti-dilutive. We had no anti-dilutive options that were excluded from the calculation of earnings per share for any period presented.

Amortization expense amounted to $2.4 million for the three months ended March 31, 2009 and
$1.5 million for three months ended March 31, 2008.

Estimated annual amortization expense related to our intangible assets for the
next five years is expected to be (in millions):



|  |  |      |  |   |    
|- |  | ---- |  | - | ---
| |  | 2009 |  | $ | 8.9
| |  | 2010 |  | $ | 8.3
| |  | 2011 |  | $ | 8.0
| |  | 2012 |  | $ | 6.9
| |  | 2013 |  | $ | 6.5

We amortize the cost of the customer base intangible by an accelerated method and the cost of the
remaining intangible assets by the straight-line method over their economic lives. We generally amortize contracts over 1.5 to 10 years and formulas, as well as the customer base, over 20 years.

On January 5, 2009, we entered into a Supplement Agreement to increase the commitment level
of the revolving credit facility by $5 million. Subsequently, on March 24, 2009, we entered into a Second Amendment to the Second Amended and Restated Revolving Credit Agreement (Second Amendment). The Second Amendment increased the commitment
level by an additional $5 million, increased the letter of credit commitment level from $50 million to $75 million, increased the interest rate paid for borrowings, and amended certain defined terms and covenant calculations. Additionally, on
March 24, 2009, we entered into a Supplement Agreement to the Second Amended and Restated Revolving Credit Agreement to increase the commitment level of the revolving credit facility by $2.25 million. All of these transactions resulted in a
commitment level of $119.25 million at March 31, 2009. We paid financing costs of $300 thousand related to the Second Amendment and the two Supplement Agreements, which will be amortized over the remaining term of the revolving credit facility.
We had outstanding letters of credit of $12.4 million at March 31, 2009, resulting in the unused portion of the revolving credit facility amounting to $106.8 million.

On April 20, 2009, we entered into an agreement to add an additional lender under our revolving credit facility and increase the commitment level by $10 million. This results in the total commitment level of
$129.25 million at April 20, 2009.



|8. | Contractual Commitments and Contingencies
|-- | -----------------------------------------

There
have been no significant changes in our contractual commitments from those reported in our 2008 Annual Report in Note 17 of the Notes to Consolidated Financial Statements.

Litigation

We are involved in
legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve
governmental authorities. For further information, see Environmental below.

While it is not possible to predict or determine
with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition or results of operations.

Environmental

During 2000, the U.S. Environmental Protection Agency (EPA) named us as a potentially responsible party (PRP) under Superfund law for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in
Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies.

The Sauget Area 2 Site PRPs are currently working with the EPA to submit an acceptable Remedial Investigation and Feasibility Study (RI/FS) to the EPA,
which we expect to occur in late 2009. We have accrued our estimated proportional share of the expenses for the RI/FS, as well as our best estimate of our proportional share of the remediation liability proposed in our ongoing discussions and
submissions with the agencies involved. The amount currently accrued for this site is not material.

At a former TEL plant site located in
the state of Louisiana, we have completed significant environmental remediation, although we will be monitoring and treating the site for an extended period. The accrual for this site was $8.5 million at March 31, 2009 and $8.8 million at
December 31, 2008. We based these amounts on the best estimate of future costs discounted at approximately 2% in both 2009 and 2008. We incorporated an inflation factor in determining the discount rate. The undiscounted liability was $9.4
million at March 31, 2009 and $9.6 million at December 31, 2008. The expected payments for each of the next five years amount to approximately $600 thousand. Expected payments thereafter amount to approximately $6 million.

At a plant site in Houston, Texas, we have an accrual of $6.1 million at March 31, 2009 and $6.7 million at December 31, 2008 for environmental
remediation, dismantling, and decontamination. Included in these amounts are $5.4 million at March 31, 2009 and $5.8 million at December 31, 2008 for remediation. A portion of the accrual for this site is discounted at approximately 4% at
both March 31, 2009 and December 31, 2008 and includes an inflation factor. The undiscounted accrual for this site was $7.0 million at March 31, 2009 and $7.8 million at December 31, 2008. The expected payments for each of the
next five years amount to approximately $400 thousand for the portion of the accrual for this site which is discounted. Expected payments thereafter for the portion of the accrual for this site which is discounted amount to approximately $2.6
million.

The remaining environmental liabilities are not discounted.

We accrue for environmental remediation and monitoring activities for which costs can be reasonably estimated and are probable. These estimates are based
on an assessment of the site, available clean-up methods, and prior experience in handling remediation. While we believe we are currently fully accrued for known environmental issues, it is possible that unexpected future costs could have a
significant impact on our financial position and results of operations.

Our total accruals for environmental remediation were approximately
$21.1 million at March 31, 2009 and $20.6 million at December 31, 2008. In addition to the accruals for environmental remediation, we also have accruals for dismantling and decommissioning costs of $1.1 million at March 31, 2009 and
$1.3 million at December 31, 2008.

Letters of Credit and Guarantees

We have outstanding guarantees with several financial institutions in the amount of $30.4 million at March 31, 2009. The guarantees are secured by
letters of credit, as well as cash collateral. The outstanding letters of credit amounted to $12.4 million at March 31, 2009, all of which were issued under the letter of credit sub-facility of our revolving credit facility. See Note 7 in the
Notes to Consolidated Financial Statements. The letters of credit primarily relate to insurance guarantees and the interest rate

lock agreement discussed below. We renew letters of credit as necessary. The remaining amounts represent performance, lease, custom and excise tax
guarantees. Expiration dates range from 2009 to 2012. Some of the guarantees have no expiration date.

We cannot estimate the maximum amount
of potential liability under the letters of credit and guarantees. However, we accrue for potential liabilities when a future payment is probable and the range of loss can be reasonably estimated.

Interest Rate Lock Agreement

The construction loan for the Foundry Park I project to construct an office building for MeadWestvaco is being financed by a group of banks and matures in August 2010. Prior to commencing construction, we took actions to identify the
possible permanent lending source after construction. To that end, Foundry Park I entered into an Application with Principal Commercial Funding II, LLC (Principal) dated February 26, 2007 which outlined the terms and conditions under which
Principal would provide permanent, fixed-rate financing in the maximum amount of $116,000,000 amortized over 25 years with all amounts due 13.5 years after the date of the loan. The Application was not a loan commitment due to the lengthy time
period of thirty-four months until the completion of the building.

In order to obtain a fixed-rate loan, we entered into a Rate Lock
Agreement with Principal dated February 26, 2007. Principal simultaneously entered into a hedge with a third party based mainly on the forward rates of ten-year Treasuries. At the time, ten-year Treasuries were trading at approximately 4.63%.
We are not party to that hedging agreement. Under the Rate Lock Agreement, we agreed to post a deposit with Principal and to increase the amount of that deposit if the exposure to Principal on the hedge increased. As of March 31, 2009, the
forward swap yield on ten-year Treasuries has dropped, and we have fully complied with all deposit requirements. As of March 31, 2009, we have deposited approximately $22.7 million with Principal, including $14.5 million in cash and $8.2
million in irrevocable letters of credit. As of March 31, 2009, ten-year Treasuries were trading at 2.71%. As of April 27, 2009, our deposit requirement had decreased to approximately $19.4 million. The Rate Lock Agreement provides that
any outstanding deposits will be returned to us at the loan closing. Since we are entitled to a return of our deposits at the loan closing, the cash deposits for the Rate Lock Agreement are recorded in other assets and deferred charges on our
Consolidated Balance Sheet at March 31, 2009. In the event that the loan does not close as scheduled, we would be required to pay Principals breakage costs, including costs associated with the hedge. We do not believe it is probable that
a loss has been incurred; however, in the event that financing is not obtained through Principal or on terms substantially similar to those in the Application, the loss for the breakage fees incurred could have a material adverse impact on our
financial statements and compliance with debt covenants.

Principal has informed us that it intended to syndicate the permanent loan to
third parties. We understand that the syndication market is currently impaired, and we have no way to determine at this time when, or if, this market will recover. Principal informed us in a letter dated October 28, 2008 that it has taken the
position that it is not obligated to make the permanent loan commitment unless the syndication market recovers and the loan can be syndicated on terms acceptable to Principal. As a result of current market conditions, Principal has asserted that a
material adverse change has occurred that could impair the syndication of the proposed loan. We have disputed the occurrence of a material adverse change. Principal has further informed us that the Application remains open, but they have reserved
all of their rights. We are currently investigating possible alternative financing in the event that Principal does not make the loan on substantially all of the terms and conditions outlined in the Application. We have until August 2010 before
financing needs to be in place. We cannot predict the financing terms which will be available at that time.

|9. | Derivatives and Hedging Activities
|-- | ----------------------------------

Accounting Policy for Derivative Instruments and Hedging Activities

As required by SFAS 133, we record all
derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply
hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm
commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted
transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or
loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted
transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain of our risk, even though hedge accounting does not apply or we elect not to apply hedge accounting under SFAS 133. We do not
enter into derivative instruments for speculative purposes.

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We primarily manage our exposures to a wide variety of
business and operational risks through management of our core business activities.

We manage certain economic risks, including interest
rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding, as well as through the use of derivative financial instruments. Specifically, we have entered into an interest rate swap to manage our
exposure to interest rate movements on the Foundry Park I construction loan and add stability to capitalized interest expense. Further information on the construction loan is in our 2008 Annual Report in Note 12 of the Notes to Consolidated
Financial Statements.

Our foreign operations expose us to fluctuations of foreign exchange rates. These fluctuations may impact the value
of our cash receipts and payments as compared to our functional currency, the U.S. Dollar. To manage this exposure, we sometimes enter into foreign currency forward contracts to minimize currency exposure due to cash flows from foreign operations.

Cash Flow Hedge of Interest Rate Risk

The interest rate swap related to the Foundry Park I construction loan is designated and qualifies as a cash flow hedge under SFAS 133. As such, the effective portion of changes in the fair value of the swap is
recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of changes in the fair value of the swap is recognized
immediately in earnings. We assess the effectiveness of the swap quarterly by comparing the changes in the fair value of the derivative hedging instrument with the change in present value of the expected future cash flows on the hedged transaction.

The interest rate swap involves the receipt of variable-rate amounts based on LIBOR in exchange for
fixed-rate payments over the life of the agreement without exchange of the underlying notional amount. The fixed-rate payments are at a rate of 4.975%. The notional amount of the swap was approximately $62.7 million at March 31, 2009 and $52.9
million at December 31, 2008 and accretes to approximately $94 million over the term of the swap. The accreting notional amount is necessary to maintain the swap notional at an amount that represents approximately 85% of the projected
construction loan principal balance over the loan term. The maturity date of the swap is January 1, 2010.

Information on the amounts
and location in our financial statements of the fair value, loss in other comprehensive income, and ineffectiveness of the interest rate swap is shown in the tables below. The unrealized loss, net of tax, related to the fair value of the interest
rate swap and recorded in accumulated other comprehensive loss in shareholders equity on the Consolidated Balance Sheets, amounted to approximately $1.5 million at March 31, 2009 and $1.9 million at December 31, 2008. Also recorded
as a component of accumulated other comprehensive loss in shareholders equity on the Consolidated Balance Sheets was the net amount of swap receipts and payments made since the inception of the swap. This amounted to approximately $900
thousand, net of tax, at March 31, 2009 and $400 thousand, net of tax, at December 31, 2008. Any amounts remaining in accumulated other comprehensive loss related to the swap will be recognized in the Consolidated Statements of Income over
the depreciable life of the office building beginning at the completion of the construction project, which is currently expected to be late 2009. Approximately $15 thousand currently recognized in accumulated other comprehensive loss is expected to
be reclassified into earnings over the next twelve months.

Non-designated Hedges

In December 2008, we entered into $17 million of Euro-denominated forward contracts to minimize currency exposure from expected cash flows from foreign
operations. The forward contracts obligate us to sell Euros for U.S. Dollars at a fixed exchange rate of 1.403, which was agreed to at the inception of the contracts. These contracts have maturity dates from January 2009 to December 2009. The
outstanding Euro-denominated foreign currency forward contracts amounted to $13 million at March 31, 2009 and $17 million at December 31, 2008. Any foreign currency rate change that affects the fair value of any of these forward contract
transactions is offset by a corresponding change in the value of the Euro-denominated transactions. We elected not to use hedge accounting under SFAS 133 for these forward contracts, and therefore immediately recognized any change in the fair value
of the forward contracts directly in earnings.

Credit-risk-related Contingent Features

Under our interest rate swap, we have an agreement with our derivative counterparty that contains a provision which specifies that if we default on any of
our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations.

As of March 31, 2009, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for
nonperformance risk, related to these agreements was $2.9 million. We have not posted any collateral related to these agreements as of March 31, 2009. If we had breached any of these provisions, we could have been required to settle our
obligations under the agreements at their termination value of $2.9 million.

We determine the fair value of the derivative instruments shown in the table above by using widely
accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each instrument. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based
inputs.

The fair value of the interest rate swap is determined using the market standard methodology of netting the discounted future fixed
cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observable market interest rate curves. The fair value of the foreign currency forward
contracts is based on interest differentials between the geographical areas and market forward points. In determining the fair value measurements, we incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and
the counterparties nonperformance risk.

##### Table of Contents

Although we have determined that the majority of the inputs used to value our derivatives fall within
Level 2 of the fair value hierarchy, the credit valuation adjustment associated with the derivatives utilizes Level 3 inputs. These Level 3 inputs include estimates of current credit spreads to evaluate the likelihood of default by both us and the
counterparties to the derivatives. As of March 31, 2009, we have assessed the significance of the impact of the credit valuation adjustment on the overall valuation of our derivatives and have determined that the credit valuation adjustment is
not significant to the overall valuation of the derivatives. Accordingly, we have determined that our derivative valuations should be classified in Level 2 of the fair value hierarchy.



|12. | Recently Issued Accounting Pronouncements
|--- | -----------------------------------------

In
December 2008, the Financial Accounting Standards Board (FASB) issued FASB Staff Position No. FAS 132(R)-1, Employers Disclosures about Postretirement Benefit Plan Assets (FSP 132(R)-1). FSP 132(R)-1 provides guidance on a plan
sponsors disclosures about plan assets of defined benefit pension and postretirement plans. Required disclosures include information about categories of plan assets, fair value measurements of plan assets, and significant concentrations of
risk, as well as investment policies and strategies. FSP 132(R)-1 is effective for fiscal years ending after December 15, 2009. Except for additional disclosures, we do not expect the adoption of FSP132(R)-1 to have an impact on our financial
statements.

In April 2009, the FASB issued FASB Staff Position No. FAS 115-2 and FAS 124-2, Recognition and Presentation of
Other-Than-Temporary Impairments (FSP 115-2 and 124-2). FSP 115-2 and 124-2 amends the guidance on other-than-temporary impairment for debt securities and modifies the presentation and disclosure of other-than-temporary impairments on debt and

We conduct all of our business and derive essentially all of our income from our subsidiaries. Therefore,
our ability to make payments on the senior notes or other obligations is dependent on the earnings and the distribution of funds from our subsidiaries. There are no restrictions on the ability of any of our domestic subsidiaries to transfer funds to
the Parent Company.

The following sets forth the Consolidating Statements of Income for the three months ended March 31, 2009 and
March 31, 2008, Consolidating Balance Sheets as of March 31, 2009 and December 31, 2008, and Condensed Consolidating Statements of Cash Flows for the three months ended March 31, 2009 and March 31, 2008 for the Parent
Company, the Guarantor Subsidiaries, and Non-Guarantor Subsidiaries. The financial information is based on our understanding of the SECs interpretation and application of Rule 3-10 of the SEC Regulation S-X.

The financial information may not necessarily be indicative of results of operations or financial position had the Guarantor Subsidiaries or Non-Guarantor
Subsidiaries operated as independent entities. The Parent Company accounts for investments in these subsidiaries using the equity method.

described in any forward-looking statement, made in this discussion or elsewhere, might not occur.

Overview

Operations during the first three months of 2009 generated strong results. Operating profit in our petroleum additives segment increased significantly
over the first three months of 2008, but net sales were lower, reflecting the challenging economic environment in which we operate. Our financial position remains strong, with an increase of $37.7 million in cash since December 31, 2008. During
the first three months of 2009, we paid down $41.9 million of outstanding debt on our revolving credit facility.

Petroleum Additives Segment

Petroleum additives net sales for the first three months 2009 of $334.8 million decreased $45.8 million, or approximately 12%, from $380.6 million for the
first three months 2008. The decrease in net sales reflects the impact of the worldwide economic slowdown, as well as the destocking of inventories by many of our customers. A reduction in product shipments of 26% is reflected predominantly in the
lubricant additives product lines. Also, included in the reduction in net sales between the 2009 and 2008 three month periods is an unfavorable foreign currency impact of approximately $11 million. This unfavorable impact from foreign exchange
reflects the strengthening of the U.S. Dollar versus the other currencies in which we conduct business. Partially offsetting the unfavorable impacts from lower product shipments and foreign currency were higher selling prices.

The table below details the approximate components of the decrease between the three months ended March 31, 2008 and the three months ended
March 31, 2009.

Petroleum Additives Segment

The petroleum additives operating profit for three months 2009 increased $12.4 million when compared to three months 2008. This increase in operating
profit between the 2009 and 2008 three months periods is primarily the result of improvements in the fuel additives product lines. Fuel additives operating profit increased due to improvements in our product portfolio, increased market coverage, and
stability in market demand in an environment of rapidly declining raw material costs. The petroleum additives operating profit margin was 15.0% for three months 2009 and 9.9% for three months 2008. The 2009 three months include a benefit of
approximately $1.1 million from a LIFO liquidation, while the 2008 three months period includes a gain of $3.2 million resulting from a legal settlement related to raw materials.

In addition to the significant decrease in raw material costs, another major factor in the improvement in both operating profit and the operating profit
margin is the impact of our pricing initiatives during 2008 resulting in higher selling prices. Despite increasing selling prices in 2008, during most of last year, the continuing increase in the cost of our raw materials outpaced the selling price
increases. During the first three months of 2009, as the cost of many of those raw materials decreased, our operating profit margins improved. The significant favorable impact from lower raw material costs on our operating margins is not sustainable
at this level. If raw material costs stabilize at the current levels, we expect product selling prices will be adjusted to reflect these market conditions.

The unfavorable impact of product shipments on operating profit is discussed above in the Net Sales section. Foreign currency resulted in a small unfavorable impact of approximately $1 million when comparing operating
profit from three months 2009 with three months 2008.

Operating profit for three months 2009 has also benefitted from cost control
initiatives that we took during the fourth quarter of last year. Selling, general, and administrative expenses (SG&A), as well as research, development, and testing expenses (R&D), decreased when compared to three months 2008. SG&A
decreased approximately $2.5 million or 11% for three months 2009, while R&D decreased approximately $1.5 million or 7% when compared to the same 2008 period. The decreases were across both the lubricant additives and fuel additives product
lines in a number of cost categories and were substantially the result of a favorable foreign currency impact. We continue to invest in SG&A and R&D to support our customers programs and to develop the technology required to remain a
leader in this industry.

##### Table of Contents

The following discussion references the Consolidated Financial Statements beginning on page 3 of this
Quarterly Report on Form 10-Q.

Interest and Financing Expenses

Interest and financing expenses were $2.9 million for three months 2009 and $3.0 million for three months 2008. Average interest rates for the three
months 2009 were slightly lower than the same 2008 period. The impact of the lower interest rates was offset by higher average debt during three months 2009.

Other (Expense) Income, Net

Other expense, net for three months 2009 was $80 thousand and
represented several immaterial items. Other income, net for three months 2008 was $400 thousand and primarily represented investment income earned on excess cash.

Income Taxes

Income taxes were $14.3 million for three months 2009 and $10.2 million for
three months 2008. The effective tax rate was 33.3% for three months 2009 and 34.0% for three months 2008. The increase in income before income taxes resulted in an increase of $4.4 million in income taxes, while the decrease in the effective tax
rate from 2008 to 2009 resulted in a decrease of approximately $300 thousand in income taxes when comparing the three months 2009 and 2008 periods. The three months 2009 effective tax rate includes the benefit of lower tax rates for certain foreign
operations.

Our deferred taxes are in a net asset position. Based on our current projections, we believe that we will recover the full
benefit of our deferred tax assets and have therefore not recorded a valuation allowance.

Cash Flows, Financial Condition, and
Liquidity

Cash and cash equivalents at March 31, 2009 were $59.5 million, which was an increase of $37.7 million since
December 31, 2008 and included a $2.0 million unfavorable impact from foreign currency translation.

We expect that cash from
operations, together with borrowing available under our revolving credit facility, will continue to be sufficient to cover our operating expenses for the foreseeable future. At March 31, 2009, we had borrowing capacity under our revolving
credit facility of $106.8 million.

Cash Flows  Operating Activities

Cash flows provided from operating activities for the three months 2009 were $96.7 million and included a decrease of $50.9 million in working capital,
including lower inventories and higher accounts payable. The decrease in inventories reflects the results of our efforts to lower inventories in response to the decreased demand for our products. The increase in accounts payable reflects a normal
increase from an unusually low level of accounts payable at December 31, 2008.

##### Table of Contents

Including the change in cash, we had working capital of $280.7 million at March 31, 2009 and $310.3
million at December 31, 2008. The current ratio was 2.81 to 1 at March 31, 2009 and 3.28 to 1 at December 31, 2008.

Cash
Flows  Investing Activities

Cash used in investing activities was $19.3 million during three months 2009 and included funding of
$4.0 million for a deposit related to the interest rate lock agreement, which is discussed below. Excluding the construction of the office building by Foundry Park I, we funded capital expenditures of $8.2 million through March 31, 2009. We
estimate our total capital spending during 2009, excluding the capital expenditures by Foundry Park I, will be approximately $30 million to $35 million. We expect to continue to finance capital spending, excluding the expenditures for the
construction of the office building by Foundry Park I, through cash on hand and cash provided from operations, together with borrowing available under our revolving credit facility.

Capital expenditures during three months 2009 related to the Foundry Park I project amounted to $7.1 million. We expect capital expenditures in 2009
related to the construction of the office building will be approximately $63 million which will be substantially borrowed under our construction loan.

Cash Flows  Financing Activities

Cash used in financing activities during three months 2009
amounted to $37.6 million. The use of cash included the funding of dividends of $3.0 million, as well as debt issuance costs of $300 thousand and a payment of $250 thousand on the fourth quarter 2006 acquisition of an intangible asset. Our book
overdraft increased $1.5 million.

We had total long-term debt, including the current portion, of $201.6 million at March 31, 2009,
representing a decrease of approximately $35.5 million in our total debt since December 31, 2008. The decrease resulted from the payment of $41.9 million under the revolving credit facility and $200 thousand on capital leases, which was
partially offset by borrowings on the construction loan of $6.6 million.

In addition to the Foundry Park I construction loan which is
discussed below, at March 31, 2009, we had outstanding senior notes in the aggregate principal amount of $150 million that bear interest at a fixed rate of 7.125% and are due in 2016.

At March 31, 2009, we also have a $119.25 million revolving credit facility for general corporate purposes that bears interest at variable rates. The
revolving credit facility includes a $75 million sub-facility for letters of credit. The facility matures on December 21, 2011. At March 31, 2009, we had no outstanding borrowings under the revolving credit facility. We had outstanding
letters of credit of $12.4 million at March 31, 2009, resulting in the unused portion of the revolver amounting to $106.8 million. On April 20, 2009, we entered into an agreement to add an additional lender under our revolving credit
facility and increase the commitment level by $10 million. This results in the total commitment level of $129.25 million at April 20, 2009.

Both the senior notes and the revolving credit facility contain covenants, representations, and events of default that management considers typical of credit agreements of this nature. We were in compliance with these covenants as of both
March 31, 2009 and December 31, 2008.

As a percentage of total capitalization (total debt and shareholders equity), our
total debt decreased from 44.9% at the end of 2008 to 39.1% at March 31, 2009. The change in the percentage was primarily the result of the decrease in debt, as well as an

increase in shareholders equity. The increase in shareholders equity reflects our earnings, partially offset by the impact of dividend payments.
Normally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Foundry Park I Construction Loan
and Interest Rate Swap

Foundry Park I and NewMarket Corporation entered into a construction loan agreement with a group of banks on
August 7, 2007 to borrow up to $116 million to fund the development and construction of an office building. The construction loan bears interest at LIBOR plus a margin of 140 basis points. The term of the loan is for a period of 36 months and
is unconditionally guaranteed by NewMarket Corporation. No principal reduction payment is due during the construction period. As a condition of the construction loan and concurrently with the closing of the loan, Foundry Park I also obtained
interest rate risk protection in the form of an interest rate swap. The interest rate swap is discussed in Note 9 in the Notes to Consolidated Financial Statements.

Interest Rate Lock Agreement

The construction loan for the Foundry Park I project to construct an
office building for MeadWestvaco is being financed by a group of banks and matures in August 2010. Prior to commencing construction, we took actions to identify the possible permanent lending source after construction. To that end, Foundry Park I
entered into an Application with Principal Commercial Funding II, LLC (Principal) dated February 26, 2007 which outlined the terms and conditions under which Principal would provide permanent, fixed-rate financing in the maximum amount of
$116,000,000 amortized over 25 years with all amounts due 13.5 years after the date of the loan. The Application was not a loan commitment due to the lengthy time period of thirty-four months until the completion of the building.

In order to obtain a fixed-rate loan, we entered into a Rate Lock Agreement with Principal dated February 26, 2007. Principal simultaneously entered
into a hedge with a third party based mainly on the forward rates of ten-year Treasuries. At the time, ten-year Treasuries were trading at approximately 4.63%. We are not party to that hedging agreement. Under the Rate Lock Agreement, we agreed to
post a deposit with Principal and to increase the amount of that deposit if the exposure to Principal on the hedge increased. As of March 31, 2009, the forward swap yield on ten-year Treasuries has dropped, and we have fully complied with all
deposit requirements. As of March 31, 2009, we have deposited approximately $22.7 million with Principal, including $14.5 million in cash and $8.2 million in irrevocable letters of credit. As of March 31, 2009, ten-year Treasuries were
trading at 2.71%. As of April 27, 2009, our deposit requirement had decreased to approximately $19.4 million. The Rate Lock Agreement provides that any outstanding deposits will be returned to us at the loan closing. Since we are entitled to a
return of our deposits at the loan closing, the cash deposits for the Rate Lock Agreement are recorded in other assets and deferred charges on our Consolidated Balance Sheet at March 31, 2009. In the event that the loan does not close as
scheduled, we would be required to pay Principals breakage costs, including costs associated with the hedge. We do not believe it is probable that a loss has been incurred; however, in the event that financing is not obtained through Principal
or on terms substantially similar to those in the Application, the loss for the breakage fees incurred could have a material adverse impact on our financial statements and compliance with debt covenants.

Principal has informed us that it intended to syndicate the permanent loan to third parties. We understand that the syndication market is currently
impaired, and we have no way to determine at this time when, or if, this market will recover. Principal informed us in a letter dated October 28, 2008 that it has taken the position that it is not obligated to make the permanent loan

commitment unless the syndication market recovers and the loan can be syndicated on terms acceptable to Principal. As a result of current market conditions,
Principal has asserted that a material adverse change has occurred that could impair the syndication of the proposed loan. We have disputed the occurrence of a material adverse change. Principal has further informed us that the Application remains
open, but they have reserved all of their rights. We are currently investigating possible alternative financing in the event that Principal does not make the loan on substantially all of the terms and conditions outlined in the Application. We have
until August 2010 before financing needs to be in place. We cannot predict the financing terms which will be available at that time.

Critical Accounting Policies

This report, as well as the 2008 Annual Report, includes a discussion of our accounting
principles, as well as methods and estimates used in the preparation of our financial statements. We believe these discussions and financial statements fairly represent the financial position and operating results of our company in all material
respects. The purpose of this portion of our discussion is to further emphasize some of the more critical areas where a significant change in facts and circumstances in our operating and financial environment might cause a change in reported
financial results.

Intangibles, Net of Amortization and Goodwill

We have certain identifiable intangibles, as well as goodwill, amounting to $51.7 million at March 31, 2009. These intangibles relate to our
petroleum additives business and, except for the goodwill, are being amortized over periods with up to approximately twenty years of remaining life. We continue to assess the market related to these intangibles, as well as their specific values, and
have concluded the values and amortization periods are appropriate. We also evaluate these intangibles for any potential impairment when significant events or circumstances occur that might impair the value of these assets. These evaluations
continue to support the value at which these identifiable intangibles are carried on our financial statements. However, if conditions were to substantially deteriorate in this market, it could possibly cause a reduction in the periods of the
amortization charge or result in a noncash write-off of a portion of the intangibles carrying value. A reduction in the amortization period would have no effect on cash flows. We do not anticipate such a change in the market conditions.

Environmental and Legal Proceedings

We have made disclosure of our environmental issues in Part I, Item 1 of the 2008 Annual Report, as well as in the Notes to Consolidated Financial Statements included in the 2008 Annual Report. We have made
additional disclosures in Part I, Item 1 of this Form 10-Q. We believe our environmental accruals are appropriate for the exposures and regulatory guidelines under which we currently operate. While we currently do not anticipate significant
changes to the many factors that could impact our environmental requirements, we continue to keep our accruals consistent with these requirements as they change.

Also, as noted in the discussion of Legal Proceedings in Part II, Item 1 of this Quarterly Report on Form 10-Q and Part I, Item 3 of the 2008 Annual Report, while it is not possible to predict or
determine with certainty the outcome of any legal proceeding, it is our opinion, based on our current knowledge, that we will not experience materially adverse effects on our results of operations or financial condition as a result of any pending or
threatened proceeding.

Pension Plans and Other Postretirement Benefits

We use assumptions to record the impact of the pension and postretirement plans in the financial statements. These assumptions include the discount rate,
expected long-term rate of return on plan assets, rate of compensation increase, and health care cost trend rate. A change in any one of these assumptions could result in different results for the plans. We develop these assumptions after
considering available information that we deem relevant. Information is provided on the pension and postretirement plans in Note 18 of the 2008 Annual Report. In addition, further disclosure on the effect of changes in these assumptions is provided
in the Financial Position and Liquidity section of Part II, Item 7 of the 2008 Annual Report.

We file consolidated U.S. federal income and both consolidated and individual state income tax returns, as well as individual foreign
income tax returns, under which assumptions may be made to determine the deductibility of certain costs. We make estimates related to the impact of tax positions taken on our financial statements when we believe the tax position is more likely than
not to be upheld on audit. In addition, we make certain assumptions in the determination of the estimated future recovery of deferred tax assets.

Interest Rate Lock Agreement

Evaluation of the interest rate lock agreement related to the application for permanent
financing on the Foundry Park I project requires significant management judgment. See Note 8 in the Notes to Consolidated Financial Statements for further information.

Recently Issued Accounting Pronouncements

For a full discussion of the more significant
pronouncements which may impact our financial statements, see the Notes to Consolidated Financial Statements.

Outlook

We have begun the year with excellent results for our business. The results of the past two quarters highlight our ability to
manage our business during challenging periods and demonstrate the value of diversity in our product lines, customer base, and the geographic areas in which we operate. Despite the success of the first three months of the year, there continues
to be uncertainty related to the ultimate demand for our products. While our products are necessary for modern machinery to operate, the worldwide economic slowdown has lowered overall demand, especially in the lubricant additives product lines
of the petroleum additives segment. We expect that overall market demand, as measured by volume, may decrease 10% to 12% for the year 2009 as compared to 2008. We believe that excluding the effects of destocking, the underlying market demand
may be 5% to 8% lower for the year.

For the remainder of the year, we will continue to manage our business by remaining focused on
long-term goals, but also recognizing and addressing the challenges of the market in which we currently operate. Our margins are recovering, which allow us to continue our investment in R&D programs and deliver measurable value to our
customers, as well as reward our shareholders. After several years of low operating margins caused by rapid cost increases, our margins returned to an acceptable level during the first three months of 2009. While our margins for the first three
months were very good, for the four quarters ended March 31, 2009, our margin was 9.1%, which is below the margins we believe are necessary to continue to deliver quality goods and services to the petroleum additives industry.

The project to develop some of the downtown Richmond property that we own by constructing a multi-story
office building for MeadWestvaco continues to progress as expected. Total expenditures on this project for 2009 are projected to be approximately $63 million, which would bring the total project to approximately $130 million. We anticipate the
project will be completed by the end of 2009 and that the tenant will begin taking occupancy at that time.

As we have communicated in the
past, we intend to leverage our financial strength to increase shareholder value by growing the business, with acquisitions being an area of primary interest. Our primary focus in the acquisition area remains on the petroleum additives
industry. It is our view that this industry will provide the greatest opportunity for a good return on our investment while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. Nonetheless,
we are patient in this pursuit and intend to make the right acquisition for our company when the opportunity arises. Meanwhile, we believe we have many internal opportunities for growth in the near term, from both geographical and product line
extensions. Until an acquisition materializes, we will build cash on our balance sheet and will continue to evaluate all alternative uses for that cash to enhance shareholder value, including stock repurchases and dividends.



|ITEM 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

Other than our foreign currency risk, there have been no significant changes in our market risk from the information provided in the 2008 Annual Report.

At March 31, 2009, we had $12.6 million in Euro-denominated foreign currency forward contracts outstanding. With other variables held constant, a
hypothetical 10% adverse change in the March 31, 2009 forward Euro rates would have resulted in a decrease of approximately $1.2 million in the value of the contracts.



|ITEM 4. | Controls and Procedures
|------- | -----------------------

Evaluation
of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but
not absolute, assurance of the reliability of the financial records and the protection of assets. Our controls and procedures include written policies and procedures, careful selection and training of qualified personnel, and an internal audit
program. We use a third-party firm, separate from our independent registered public accounting firm, to assist with internal audit services.

We work closely with the business groups, operations personnel, and information technology to ensure transactions are recorded properly. Environmental and legal staff are consulted to determine the appropriateness of our environmental and
legal liabilities for each reporting period. We regularly review the regulations and rule changes that affect our financial disclosures.

##### Table of Contents

Our disclosure control procedures include signed representation letters from our regional officers, as
well as senior management.

We have formed a Financial Disclosure Committee, which is made up of the president of Afton, the general counsel
of NewMarket, and the controller of NewMarket. The committee, as well as regional management, makes representations with regard to the financial statements that, to the best of their knowledge, the report does not contain any misstatement of a
material fact or omit a material fact that is necessary to make the statements not misleading with respect to the periods covered by the report.

The committee and the regional management also represent, to the best of their knowledge, that the financial statements and other financial information included in the report fairly present, in all material respects, the financial
condition, results of operations and cash flows of the company as of and for the periods presented in the report.

Pursuant to Rule
13a-15(b) under the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of
our disclosure controls and procedures (as defined under Rule 13a-15(e)) under the Exchange Act as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer
concluded that our disclosure controls and procedures are effective.

There has been no change in our internal control over financial
reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the quarter ended March 31, 2009, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II  Other Information



|ITEM 1. | Legal Proceedings
|------- | -----------------

We are involved in legal
proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental
authorities. For further information, see Environmental in Part I, Item 1 of our 2008 Annual Report.

While it is not
possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition or
results of operations.
