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 statement of, in all material respects, our consolidated financial position and shareholders’ equity as of June 30, 2010 and December 31, 2009, as well as our consolidated results of operations for the second quarter and six months ended June 30, 2010 and June 30, 2009, and cash flows for the six months ended June 30, 2010 and June 30, 2009. 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 year ended December 31, 2009 (2009 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the six month period ended June 30, 2010 are not necessarily indicative of the results to be expected for the full year ending December 31, 2010. The December 31, 2009 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.

Certain amounts in the accompanying financial statements have been reclassified to conform to the current presentation. There was no effect on net income.

At both June 30, 2010 and December 31, 2009, 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 75 cents per share for the six months ended June 30, 2010 and 45 cents per share for the six months ended June 30, 2009 were declared and paid as shown in the table below.

Year	Date Declared	Date Paid	Per Share Amount
2010	February 18, 2010	April 1, 2010	37.5 cents
	April 22, 2010	July 1, 2010	37.5 cents
2009	February 19, 2009	April 1, 2009	20 cents
	April 23, 2009	July 1, 2009	25 cents

2. Acquisition of Business

On March 5, 2010, Afton Chemical Corporation (Afton) completed the acquisition of 100% of the Polartech group of companies (Polartech) for $43.7 million in cash. Polartech is a global company specializing in the supply of metalworking additives. The acquisition agreement included all physical assets of the Polartech business including the headquarters, research and development, and manufacturing facilities in the United Kingdom, as well as manufacturing sites in India, China, and the United States.

7

At March 31, 2010, we were still finalizing the purchase price allocation and recognized assets of $45.6 million in “Other assets and deferred charges” and liabilities of $1.8 million in “Accrued expenses” on the Consolidated Balance Sheets. During the second quarter, we performed a valuation of the assets acquired to determine the purchase price allocation. The purchase price valuation resulted in the recognition of $6 million of identifiable intangibles, including formulas and technology, customer base, and trademarks/trade names. We also acquired property, plant, and equipment of $28.4 million, as well as working capital.

As part of the acquisition, we recorded $4.2 million of goodwill, which resulted from deferred taxes which were recognized related to the acquisition. All of the goodwill recognized is part of the petroleum additives segment, and none is deductible for tax purposes.

Pro forma consolidated results of operations for the six months ended June 30, 2010 and June 30, 2009 assuming the acquisition had occurred on January 1, 2010 or January 1, 2009, would not be materially different from the actual results reported for the six months ended June 30, 2010 and June 30, 2009.

3. Asset Retirement Obligations

Our asset retirement obligations are related primarily to tetraethyl lead (TEL) operations. The following table illustrates the activity associated with our asset retirement obligations for the six months ended June 30, 2010 and June 30, 2009.

	2010			2009

Asset retirement obligations, January 1	$	3,031		$	3,009

Accretion expense		72			98
Liabilities settled		0			(1,539	)
Changes in expected cash flows and timing		(110	)		(526	)
Asset retirement obligations, June 30	$	2,993		$	3,042

4. Segment Information

The tables below show our consolidated revenue, operating profit (including a reconciliation of segment operating profit to consolidated income before income taxes), and depreciation and amortization.

The “All other” category includes the operations of the TEL business (primarily sales of TEL in North America), as well as certain contract manufacturing Ethyl Corporation (Ethyl) provides to Afton and to third parties.

(a) The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

We made cash contributions of approximately $3.2 million for our foreign pension plans and approximately $80 thousand for a foreign postretirement benefit plan during the six months ended June 30, 2010.

In March 2010, the Patient Protection and Affordable Care Act was signed into law, as was a related reconciliation bill. Included in the provisions of the laws are changes to the taxation related to the federal subsidy available to companies that provide retiree healthcare benefit plans that include a benefit that is at least actuarially equivalent to the benefits of Medicare Part D. Our retiree medical plan does include a drug subsidy benefit that is actuarially equivalent to Medicare Part D. However, we are not impacted by the changes in the taxation of the federal subsidy, as we assigned the subsidy to our insurance provider several years ago in consideration of premium determination. At the time we assigned the benefit to our insurance provider, we adjusted our deferred taxes accordingly. We are currently evaluating all of the provisions of the law and its impact on our company but have made no adjustments to our financial statements as a result of the legislation.

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.

The increase in intangibles and goodwill since December 31, 2009 was the result of the purchase of Polartech.

Amortization expense was (in millions):

•     Second quarter ended June 30, 2010	$	2.2
•     Six months ended June 30, 2010	$	4.4
•     Second quarter ended June 30, 2009	$	2.2
•     Six months ended June 30, 2009	$	4.6

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

•     2010	$	8.9
•     2011	$	8.2
•     2012	$	7.6
•     2013	$	6.8
•     2014	$	6.4

Generally, 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 estimated economic lives. We generally amortize contracts over 1.5 to 6 years and the customer base, as well as formulas and technology over 5 to 20 years. Trademarks and the trade name are amortized over 10 years.

Current maturities of long-term debt		(3,199	)		(33,881	)
	$	232,935		$	216,200

We had outstanding borrowings under our revolving credit facility of $18.0 million at June 30, 2010. We had no outstanding borrowings on the revolving senior credit facility at December 31, 2009. We had outstanding letters of credit of $10.3 million at June 30, 2010, resulting in the unused portion of the revolving senior credit facility amounting to $121.7 million.

On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million. The loan, which is collateralized by the Foundry Park I office building, is for a period of five years, with two thirteen-month extension options. NewMarket Corporation is fully guaranteeing the loan. The mortgage loan bears interest at a variable rate of LIBOR plus a margin of 400 basis points, with a minimum LIBOR of 200 basis points. Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate of the loan to a fixed interest rate by setting LIBOR at 2.642 for five years. Further information on the interest rate swap is in Note 10. Principal payments on the loan are being made monthly based on a 15-year amortization schedule, with all remaining amounts due in five years, unless we exercise the extension options. On January 29, 2010, we paid off the outstanding balance of $99.1 million on the Foundry Park I construction loan with proceeds of $68.4 million from the Foundry Park I mortgage loan agreement, as well as cash on hand of $30.7 million.

We were in compliance with all covenants under our debt agreements at June 30, 2010 and December 31, 2009.

9. Contractual Commitments and Contingencies

There have been no significant changes in our contractual commitments and contingencies from those reported in our 2009 Annual Report on Form 10-K in Note 19. The information below provides information on certain contractual commitments and contingencies.

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.

15

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 received notice of approval from the EPA of their October 2009 Human Health Risk Assessment. Additionally, the PRPs have submitted their Feasibility Study (FS) to the EPA Remedy Review Board. We have accrued our estimated proportional share of the expenses for the 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. We do not believe there is any additional information available as a basis for revision of the liability that we have established. The amount currently accrued for this site is not material.

At a former TEL plant site located in 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 $7.1 million at June 30, 2010 and $7.5 million at December 31, 2009. We based these amounts on the best estimate of future costs discounted at approximately 3% in both 2010 and 2009. An inflation factor is included in the estimate. The undiscounted liability was $9.1 million at June 30, 2010 and $9.7 million at December 31, 2009. The expected payments over the next five years amount to approximately $800 thousand in each of 2010 and 2011, $700 thousand in 2012, $500 thousand in 2013, and $600 thousand in 2014. Expected payments thereafter amount to approximately $6.2 million.

At a plant site in Houston, Texas, we have accruals of $7.9 million at both June 30, 2010 and December 31, 2009 for environmental remediation, dismantling, and decontamination. Included in these amounts are $7.6 million at both June 30, 2010 and December 31, 2009 for remediation. Of the total remediation, $7.2 million at both June 30, 2010 and December 31, 2009 relates to remediation of groundwater and soil. The accruals for this site are discounted at approximately 3% at both June 30, 2010 and December 31, 2009. The accruals include an inflation factor. The undiscounted accrual for this site was $11.5 million at June 30, 2010 and $11.2 million at December 31, 2009. The expected payments over the next five years are approximately $400 thousand in 2010, $500 thousand in each of 2011and 2012, $700 thousand in 2013, and $1.7 million in 2014. Expected payments thereafter amount to approximately $7.9 million.

At a Superfund site in Louisiana, we have an accrual of $2.1 million at June 30, 2010 and $2.6 million at December 31, 2009 for environmental remediation. The accrual for this site was discounted at approximately 3% at both June 30, 2010 and December 31, 2009 and included an inflation factor. The undiscounted accrual for this site was $2.7 million at June 30, 2010 and $3.2 million at December 31, 2009. The expected payments over the next five years amount to approximately $400 thousand in each of 2010 and 2011, and $200 thousand each for years 2012 through 2014. Expected payments thereafter amount to approximately $1.8 million.

The remaining environmental liabilities are not discounted.

16

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 $23.2 million at June 30, 2010 and $22.0 million at December 31, 2009. In addition to the accruals for environmental remediation, we also have accruals for dismantling and decommissioning costs of $500 thousand at both June 30, 2010 and December 31, 2009.

Letters of Credit and Guarantees

We have outstanding guarantees with several financial institutions in the amount of $49.6 million at June 30, 2010. The guarantees are secured by letters of credit, as well as cash collateral. A portion of these guarantees is unsecured. The outstanding letters of credit amounted to $10.3 million at June 30, 2010, all of which were issued under the letter of credit sub-facility of our revolving credit facility. The letters of credit primarily relate to insurance guarantees and performance guarantees. We renew letters of credit as necessary. The remaining amounts represent additional performance, lease, custom and excise tax guarantees, as well as a cash deposit of $26.8 million related to the Goldman Sachs Bank USA (Goldman Sachs) interest rate swap. The cash deposit is recorded in “Other assets and deferred charges” on the Consolidated Balance Sheet. Expiration dates of the letters of credit and certain guarantees range from the second half of 2010 to 2011. Some of the guarantees have no expiration date.

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

10. Derivatives and Hedging Activities

Accounting Policy for Derivative Instruments and Hedging Activities

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. We do not enter into derivative instruments for speculative purposes.

17

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 interest rate swaps to manage our exposure to interest rate movements.

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 reporting 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

In January 2010, we entered into an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I mortgage loan and to reduce variability in interest expense. Further information on the mortgage loan is in Note 8. We also had 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. The Foundry Park I construction loan interest rate swap matured on January 1, 2010. Further information on the construction loan is in our 2009 Annual Report in Note 13. Both interest rate swaps are designated and qualify as a cash flow hedge. As such, the effective portion of changes in the fair value of the swaps is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of changes in the fair value of the swap is recognized immediately in earnings. We assess the effectiveness of the mortgage loan interest rate swap quarterly, just as we assessed the effectiveness of the construction loan interest rate 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 of the hedged transaction.

Both interest rate swaps involve 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 2.642% for the mortgage loan interest rate swap, while the fixed-rate payments on the construction loan interest rate swap were at a rate of 4.975%. The notional amount of the mortgage loan interest rate swap was $68.4 million at origination and approximately $67.6 million at June 30, 2010. The notional amount of the mortgage loan swap amortizes to approximately $53.7 million over the term of the swap. The amortizing notional amount is necessary to maintain the swap notional at an amount that matches the declining mortgage loan principal balance over the loan term. The mortgage loan interest swap matures on January 25, 2015. The notional amount of the construction loan interest rate swap was approximately $94.0 million at December 31, 2009, just prior to its January 1, 2010 maturity. The accreting notional amount was necessary to maintain the construction loan interest rate swap notional at an amount that represented approximately 85% of the projected construction loan principal balance over the loan term.

The unrealized loss, net of tax, related to the fair value of the mortgage loan interest rate swap is recorded in accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets, amounted to approximately $1.6 million at June 30, 2010. The unrealized loss, net of tax, related to the fair value of the construction loan interest rate swap and recorded in

18

accumulated other comprehensive loss amounted to approximately $37 thousand at December 31, 2009. Also recorded as a component of accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets was the accumulated losses related to the construction loan interest rate swap. This amounted to approximately $2.6 million, net of tax, at both June 30, 2010 and December 31, 2009. The amounts remaining in accumulated other comprehensive loss related to the construction loan interest rate swap are being recognized in the Consolidated Statements of Income over the depreciable life of the office building beginning in January 2010. Approximately $900 thousand, net of tax, currently recognized in accumulated other comprehensive loss related to both the construction loan interest rate swap and the mortgage loan interest rate swap is expected to be reclassified into earnings over the next twelve months.

Non-designated Hedges

On June 25, 2009, we entered into an interest rate swap with Goldman Sachs in the notional amount of $97 million and with a maturity date of January 19, 2022 (Goldman Sachs interest rate swap). NewMarket entered into the Goldman Sachs interest rate swap in connection with the termination of a loan application and related rate lock agreement between Foundry Park I and Principal Commercial Funding II, LLC (Principal). See Note 19 in our 2009 Annual Report for further information on the transaction between Foundry Park I and Principal. When the rate lock agreement was originally executed in 2007, Principal simultaneously entered into an interest rate swap with a third party to hedge Principal’s exposure to fluctuation in the ten-year Treasuries rate. Upon the termination on June 25, 2009 of the rate lock agreement, Goldman Sachs both assumed Principal’s position with the third party and entered into an offsetting interest rate swap with NewMarket. Under the terms of this interest rate swap, NewMarket will make fixed rate payments at 5.3075% and Goldman Sachs will make variable rate payments based on three-month LIBOR. We have collateralized this exposure through cash deposits posted with Goldman Sachs amounting to $26.8 million at June 30, 2010. This transaction effectively preserves the impact of the original rate lock agreement for the possible application to a future loan amount of $97 million of a similar structure.

In December 2008, we entered into $16.8 million of Euro-denominated forward contracts to minimize foreign currency exposure from expected cash flows from foreign operations. The forward contracts obligated 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 had maturity dates through December 2009. There were no outstanding foreign currency forward contracts at June 30, 2010 or December 31, 2009.

We do not use hedge accounting for both the Goldman Sachs interest rate swap and the forward contracts, and therefore, immediately recognized any change in the fair value of these derivative financial instruments in earnings.

Credit-risk-related Contingent Features

We have agreements with both of our current derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of indebtedness is accelerated by the lender due to our default on the indebtedness.

As of June 30, 2010, 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 $25.5 million. We have minimum collateral posting thresholds with one of our derivative counterparties and have posted cash collateral of $26.8 million as of June 30, 2010. If required, we could have settled our obligations under the agreements at their termination value of $25.5 million at June 30, 2010.

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 swaps 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. In determining the fair value measurements, we incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and the counterparties’ nonperformance risk.

23

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 June 30, 2010, 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.

We record the value of our long-term debt at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk.

	June 30, 2010						December 31, 2009

13. Consolidating Financial Information

The 7.125% senior notes due 2016 are fully and unconditionally guaranteed by certain of our subsidiaries (Guarantor Subsidiaries) on a joint and several unsecured senior basis. The Guarantor Subsidiaries include all of our existing and future 100% owned domestic restricted subsidiaries. The Guarantor Subsidiaries and the subsidiaries that do not guarantee the senior notes (the Non-Guarantor Subsidiaries) are 100% owned by NewMarket Corporation (the Parent Company). The Guarantor Subsidiaries consist of the following:

Ethyl Corporation	Afton Chemical Corporation
Ethyl Asia Pacific LLC	Afton Chemical Asia Pacific LLC
Ethyl Canada Holdings, Inc.	Afton Chemical Canada Holdings, Inc.
Ethyl Export Corporation	Afton Chemical Japan Holdings, Inc.
Ethyl Interamerica Corporation	Afton Chemical Additives Corporation
Ethyl Ventures, Inc.	Afton Chemical Intangibles LLC
Interamerica Terminals Corporation	The Edwin Cooper Corporation
NewMarket Development Corporation	NewMarket Investment Company

Gamble’s Hill, LLC	Gamble’s Hill Lab, LLC
Gamble’s Hill Landing, LLC	Gamble’s Hill Third Street, LLC
Gamble’s Hill Tredegar, LLC	Polartech Additives, Inc.

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.

New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this discussion after the date hereof, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that the events described in any forward-looking statement, made in this discussion or elsewhere, might not occur.

Overview

Operations during the first six months of 2010 continued to generate strong results with operating profit in our petroleum additives segment increasing 13.3% over six months 2009. During six months 2010, we acquired the Polartech business for $43.7 million, paid down our debt by $13.9 million, and repurchased $79.2 million of our common stock. While our cash position decreased during six months 2010 due to these transactions, our financial position remains strong. Further information on the Polartech acquisition is in Note 2.

Results of Operations

Revenue

Our consolidated revenue for the second quarter 2010 amounted to $469.8 million, representing an increase of approximately 27% from the 2009 second quarter level of $370.9 million. Similarly, six months consolidated revenue increased approximately 22% from $708.0 million for 2009 to $865.0 million for 2010. The table below shows our revenue by segment.

Consolidated Revenue by Segment

(in millions)

	Second Quarter Ended June 30				Six Months Ended June 30
	2010		2009		2010		2009
Petroleum additives	$	464.9	$	368.2	$	854.3	$	703.0
Real estate development		2.9		0.0		5.7		0.0
All other		2.0		2.7		5.0		5.0
Consolidated revenue	$	469.8	$	370.9	$	865.0	$	708.0

Petroleum Additives Segment

Petroleum additives net sales for the second quarter 2010 of $464.9 million increased $96.7 million, or approximately 26%, from $368.2 million for the second quarter 2009. The increase in sales reflects higher total product shipments of 21% including the benefit of Polartech shipments for the second quarter 2010. The increase in product shipments was across all product lines, but predominantly in the lubricant additives product lines. While recovering in 2009 from the worldwide economic slowdown, product shipments were weaker than normal during the first half of 2009. We believe the overall demand for petroleum additive products is recovering from recessionary effects and are now at pre-recessionary levels. Selling prices were also favorable when comparing the two second quarter periods. Partially offsetting these favorable impacts from higher product shipments and selling prices during the second quarter 2010, was a small unfavorable foreign currency impact. We experience unfavorable foreign currency impacts when the U.S. Dollar strengthens versus the other currencies in which we conduct business.

Six months petroleum additive net sales of $854.3 million were approximately 22% higher than six months 2009 results of $703.0 million. Similar to the second quarter results, the increase between the two six months periods reflects a 21% increase in product shipments. The increase in shipments was primarily in the lubricant additives product lines. Foreign currency resulted in a small favorable impact when comparing six months 2010 and six months 2009. Partially offsetting the favorable impacts from shipments and foreign currency was a decrease in selling prices for six months 2010 compared to the same 2009 period.

36

The table below details the approximate components, in millions, of the increase between the two second quarter and six months periods.

	Second Quarter			Six Months
	(in millions)
Period ended June 30, 2009	$	368.2		$	703.0
Increase in shipments, including changes in product mix		89.7			163.2

(Decrease) increase due to foreign currency		(2.1	)		2.9
Period ended June 30, 2010	$	464.9		$	854.3

Real Estate Development Segment

The revenue of $2.9 million for second quarter 2010 and $5.7 million for six months 2010 for the real estate development segment represents the rental of the office building which was constructed by Foundry Park I. The building was completed in late 2009 and we began recognizing rental revenue in January 2010.

All Other

The “All other” category includes the operations of the TEL business (primarily sales of TEL in North America) and certain contract manufacturing that Ethyl provides to Afton and to third parties.

Segment Operating Profit

NewMarket evaluates the performance of the petroleum additives business and the real estate development business based on segment operating profit. NewMarket Services Corporation (NewMarket Services) departments and other expenses are charged to NewMarket and each subsidiary pursuant to service agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets is included in segment operating profit.

The table below reports segment operating profit for the second quarter and six months ended June 30, 2010 and June 30, 2009.

37

Petroleum Additives Segment

The petroleum additives operating profit increased $9.0 million when comparing second quarter 2010 to second quarter 2009 and $29.3 million when comparing six months 2010 to six months 2009. The operating profit margin was 16.5% for second quarter 2010 and 18.4% for second quarter 2009. The primary reason for the lower margin in second quarter 2010 is due to the impact of increasing raw materials costs combined with selling price increase actions lagging increases in raw material costs. The operating profit margins for the six months periods were 17.2% for 2010 and 16.8% for 2009. Both the second quarter and six months 2010 results are significantly higher across the lubricant additives product lines, but lower in the fuel additives product lines.

The most significant favorable factor when comparing operating profit between both the second quarter periods and the six months periods was increased product shipments, which is discussed in the Revenue section above. While selling prices were higher when comparing second quarter 2010 and second quarter 2009, for the six month periods, selling prices remain unfavorable for 2010. The unfavorable selling prices on a year-to-date basis result from multiple selling price movements during both 2010 and 2009. The second quarter 2010 results include the adverse impact of higher raw material costs, which have exceeded the selling price increases we have achieved. As discussed above, this has resulted in the operating profit margin reduction when comparing the two second quarter periods. It is our intention to restore this reduction in the operating profit margin in the marketplace. The foreign exchange impact when comparing second quarter 2010 and second quarter 2009, as well as the six months 2010 and six months 2009, was $4 million favorable. Finally, our selling, general, and administrative expenses (SG&A), together with research, development, and testing expenses (R&D), were approximately $7.8 million, or 15.2%, higher for second quarter 2010 as compared to second quarter 2009 and were approximately $14.5 million, or 16.0%, higher for six months 2010 as compared to six months 2010.

SG&A increased approximately $6.8 million or 29.5% for second quarter 2010 compared to second quarter 2009 and $11.2 million or 25.3% when comparing the two six months periods. The increase for both second quarter 2010 and six months 2010 was primarily the result of certain growth-related costs, largely reflecting the inclusion of the Polartech operations in the second quarter 2010, as well as higher personnel-related costs and professional fees. R&D increased approximately $1.0 million, or 4.6%, for second quarter 2010 when compared to the same 2009 period. Six months 2010 R&D was $3.3 million, or 8.3%, higher than six months 2009. The increase in combined SG&A and R&D included an approximate $500 thousand unfavorable foreign currency impact for second quarter 2010 as compared to second quarter 2009 and a $2.4 million unfavorable impact when comparing the two six months periods. 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.

Real Estate Development Segment

Operating profit for the real estate development segment was $1.8 million for second quarter 2010 and $3.5 million for six months 2010, compared to zero for second quarter 2009 and an operating loss of $200 thousand for six months 2009. During 2009, the office building was under construction resulting in no rental revenue and limited non-capital expenses.

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

38

Interest and Financing Expenses

Interest and financing expenses were $4.3 million for second quarter 2010 and $2.9 million for second quarter 2009. Six months 2010 amounted to $8.3 million, while six months 2009 was $5.8 million.

The increase in interest and financing expenses between both the second quarter and six months periods for 2010 and 2009 was primarily related to the mortgage loan on the Foundry Park I office building. Prior to obtaining the mortgage loan in January 2010, the interest and financing expenses for the construction phase of the office building were capitalized.

Other Expense, Net

Other expense, net for second quarter 2010 was $9.2 million, while second quarter 2009 was $11.9 million. The amount for six months 2010 was $11.5 million, while six months 2009 was $11.9 million. These amounts for both the 2010 and 2009 periods primarily represent a loss on a derivative instrument representing an interest rate swap recorded at fair value, which we entered into on June 25, 2009. See Note 10 for additional information on the interest rate swap.

Income Tax Expense

Income tax expense was $20.6 million for second quarter 2010 and $15.7 million for second quarter 2009. The effective tax rate was 34.0% for second quarter 2010 and 33.9% for second quarter 2009. The increase in income before income tax expense resulted in an increase of $4.8 million in income taxes, while the slightly higher effective tax rate in 2010 as compared to 2009 resulted in an increase of approximately $100 thousand in income taxes when comparing the second quarter 2010 and 2009 periods.

Six months 2010 income tax expense was $40.9 million with an effective tax rate of 33.3%. Income tax expense for six months 2009 was $30.0 million with an effective tax rate of 33.6%. The increase in income before income tax expense from 2009 to 2010 resulted in an increase of $11.3 million, which was partially offset by the reduction in the effective tax rate, resulting in a decrease in income tax expense of $400 thousand.

The effective tax rate for both second quarter 2009 and six months 2009 includes the benefit of the settlement of certain income tax issues with the IRS.

Cash Flows, Financial Condition, and Liquidity

Cash and cash equivalents at June 30, 2010 were $46.6 million, which was a decrease of $105.2 million since December 31, 2009 and included a $2.3 million unfavorable impact from foreign currency translation.

We expect that cash from operations, together with borrowings available under our revolving credit facility, will continue to be sufficient to cover our operating expenses for the foreseeable future.

Cash Flows – Operating Activities

Cash flows provided from operating activities for the six months 2010 were $73.2 million and included a decrease of $38.9 million due to higher working capital levels, including higher accounts receivable and inventories, partially offset by lower prepaid expenses and higher accounts payable. The increase in accounts receivable is primarily due to higher sales levels when comparing the second quarter 2010 with the fourth quarter 2009. The increase in inventories reflects increased quantities at certain locations to respond to demand for our products. The decrease in prepaid expenses reflects a reduction in deferred taxes on intercompany profit in inventory. The fluctuation in accounts payable is normal differences in timing of payments. The changes in working capital also include the impact of the acquisition of Polartech.

39

Including cash and the current portion of long-term debt, we had working capital of $359.2 million at June 30, 2010 and $405.1 million at December 31, 2009. The current ratio was 2.88 to 1 at June 30, 2010 and 3.05 to 1 at December 31, 2009. In addition to the working capital factors discussed above, the change in the current portion of long-term debt had a significant effect on working capital levels due to the refinancing of the construction loan in January 2010, resulting in a decrease in the amount of long-term debt being due within one year.

Cash Flows – Investing Activities

Cash used in investing activities was $71.5 million during six months 2010 and included $42.0 million related to the acquisition of Polartech, as well as $18.0 million for capital expenditures and a net deposit of $11.5 million related to the Goldman Sachs interest rate swap. Further information on the interest rate swap is discussed below and in Note 10. We estimate our total capital spending during 2010 will be approximately $40 million. We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our revolving credit facility.

Cash Flows – Financing Activities

Cash used in financing activities during six months 2010 amounted to $104.6 million, including the repayment of $99.1 million for the Foundry Park I construction loan and borrowing of $68.4 million for the Foundry Park I mortgage loan. We also borrowed $18.0 million under our revolving credit facility during the second quarter 2010 and repaid $800 thousand on the mortgage loan. In addition, the use of cash included the repurchase of common stock of $79.2 million and funding of dividends of $11.0 million, as well as debt issuance costs of $1.5 million.

We had total long-term debt, including the current portion, of $236.1 million at June 30, 2010, representing a decrease of approximately $13.9 million in our total debt since December 31, 2009. The decrease resulted from borrowing $18.0 million under the revolving credit facility which was offset by the payment of the outstanding balance of $99.1 million under the construction loan agreement with proceeds of $68.4 million from the Foundry Park I mortgage loan agreement and cash on hand. We made principal payments of approximately $800 thousand on the mortgage loan, as well as $400 thousand on capital leases.

At June 30, 2010, in addition to the Foundry Park I mortgage loan and the revolving credit facility which are discussed below, 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 June 30, 2010, we also had a $150 million revolving credit facility for working capital and other general corporate purposes for NewMarket and our subsidiaries, inclusive of a $75 million sub-facility for letters of credit. Borrowings bear interest at variable rates. The facility matures on December 21, 2011. At June 30, 2010, we had $18.0 million of outstanding borrowings under the revolving credit facility. We had outstanding letters of credit of $10.3 million at June 30, 2010, resulting in the unused portion of the revolver amounting to $121.7 million.

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 all covenants under both the senior notes and the revolving credit facility as of both June 30, 2010 and December 31, 2009.

40

The more restrictive and significant of the covenants under the senior notes include a minimum fixed charge ratio of 2.00, as well as a limitation on restricted payments, as defined in the agreement. Our fixed charge coverage ratio was 21.80 at June 30, 2010 and 22.62 at December 31, 2009 under the senior notes. In addition, we would have been permitted to make additional restricted payments in the amount of approximately $60 million at June 30, 2010 and $84 million at December 31, 2009 under the senior notes.

The more restrictive and significant financial covenants under the revolving credit facility include:

• Minimum consolidated net worth as defined in Section 6.3 of the Second Amended and Restated Credit Agreement;

• A minimum fixed charge coverage ratio of 1.15; and

• A maximum leverage ratio of 3.50.

Our consolidated net worth, as defined, exceeded the minimum requirement under the revolving credit facility by approximately $53 million at June 30, 2010 and approximately $102 million at December 31, 2009. Also at June 30, 2010, the fixed charge coverage ratio was 5.61 and the leverage ratio was 0.80, while at December 31, 2009 the fixed charge coverage ratio was 5.43 and the leverage ratio was 0.91.

As a percentage of total capitalization (total debt and shareholders’ equity), our total debt percentage decreased slightly from 35.3% at the end of 2009 to 35.0% at June 30, 2010. The change in the percentage was primarily the result of the decrease in debt, which was mostly offset by the decrease in shareholders’ equity. The decrease in shareholders’ equity reflects our earnings, completely offset by the impact of dividend payments and the repurchase of our common stock. Normally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Foundry Park I Mortgage Loan Agreement and Interest Rate Swap

On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million. The loan, which is collateralized by the Foundry Park I office building, is for a period of five years, with two thirteen-month extension options. NewMarket Corporation is fully guaranteeing the loan. The mortgage loan bears interest at a variable rate of LIBOR plus a margin of 400 basis points, with a minimum LIBOR of 200 basis points. Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate of the loan to a fixed interest rate by setting LIBOR at 2.642 for five years. The interest rate swap is discussed in Note 10. Principal payments on the loan are being made monthly based on a 15-year amortization schedule, with all remaining amounts due in five years, unless we exercise the extension option.

Interest Rate Lock Agreement and Goldman Sachs Interest Rate Swap

We financed the construction loan for the Foundry Park I project to construct an office building for MeadWestvaco through a group of banks. 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 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 then 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

41

Treasuries. We were not a 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 their hedge increased.

In June 2009, Principal and Foundry Park I determined that the loan terms set forth in the Application could not be syndicated based on then current market conditions. As a result, Principal and Foundry Park I terminated the loan application and related rate lock agreement and mutually released each other from their respective rights and obligations under those arrangements. See Note 10 for additional information on the termination of the rate lock agreement and subsequent entry into an interest rate swap with Goldman Sachs related to the Foundry Park I project. All amounts which we had deposited with Principal under the rate lock agreement have effectively been returned to us at the termination of the rate lock agreement as Principal transferred the deposited funds to Goldman Sachs as collateral for the interest rate swap related to the Foundry Park I project.

Other Matters

In March 2010, the Patient Protection and Affordable Care Act was signed into law, as was a related reconciliation bill. Included in the provisions of the laws are changes to the taxation related to the federal subsidy available to companies that provide retiree healthcare benefit plans that include a benefit that is at least actuarially equivalent to the benefits of Medicare Part D. Our retiree medical plan does include a drug subsidy benefit that is actuarially equivalent to Medicare Part D. However, we are not impacted by the changes in the taxation of the federal subsidy, as we assigned the subsidy to our insurance provider several years ago in consideration of premium determination. At the time we assigned the benefit to our insurance provider, we adjusted our deferred taxes accordingly. We are currently evaluating the provisions of the law and its impact on our company, but have made no adjustments to our financial statements as a result of the legislation.

Critical Accounting Policies

This report, as well as the 2009 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 $50.9 million at June 30, 2010. This amount includes approximately $10.0 million related to the Polartech acquisition earlier in 2010. These intangibles relate to our petroleum additives business and, except for the goodwill, are being amortized over periods with up to approximately eighteen 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.

42

Environmental and Legal Proceedings

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.

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 20 of the 2009 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 2009 Annual Report.

Income Taxes

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.

Outlook

We are very pleased with the performance of our businesses during the first six months. We began the year with solid results built upon a diverse product offering, customer base, and geographical presence. Our margins are good, and while we are experiencing higher raw material costs, we have demonstrated our ability in recent years to adjust our prices to compensate for increases in raw material costs. We believe the overall demand for petroleum additive products is recovering from recessionary effects. Our technology is strong, and we are well-positioned to help our customers transition to GF-5, the new passenger car motor oil specification that is being introduced in North America later this year. Our project to expand our supply chain capabilities in the Far East is proceeding, and we should begin shipping from that location later this year. We expect to continue to perform well for the remainder of the year, subject to the normal fluctuations associated with this business.

While we will be integrating Polartech into our business this year, we continue to have acquisitions as the highest priority for the use of our cash and borrowing capacity. Our primary focus for acquisitions remains in the petroleum additives industry, as we believe this will have the highest probability for success. Within petroleum additives, industrial lubricant additives and fuel additives are our main focus. We will also continue to evaluate alternative uses of our cash to enhance shareholder value, including stock repurchases and dividends.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Other than obtaining a mortgage loan and the entry into a related interest rate swap, there have been no significant changes in our market risk from the information provided in the 2009 Annual Report.

On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million, which bears interest at a variable rate of LIBOR plus a margin of 400 basis points. Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate of the loan to a fixed interest rate by setting LIBOR at 2.642 for five years. Accordingly, in combination, there is no interest rate risk associated with the mortgage loan and related interest rate swap, other than the change in the value of the interest rate swap due to changes in the yield curve. Any change in fair value is recognized immediately in accumulated other comprehensive income, to the degree of effectiveness of the swap. With other variables held constant, a hypothetical 50 basis point adverse parallel shift in the LIBOR yield curve would have resulted in an increase of approximately $1.4 million in the fair value liability of the mortgage loan interest rate swap at June 30, 2010.

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.

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

44

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 June 30, 2010, 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 2009 Annual Report and Note 9 in this Form 10-Q.

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.

On July 23, 2010, Afton Chemical Corporation and NewMarket Corporation filed a complaint in Federal District Court in Richmond, Virginia against Innospec Inc. (Innospec). The complaint alleges that Innospec violated the Robinson-Patman Act, the Virginia Antitrust Act and Virginia Business Conspiracy Act based on the disclosures that Innospec recently made in its plea agreements with the U.S. Department of Justice and the Securities and Exchange Commission, as well as the UK Serious Fraud Office. In those agreements, Innospec pled guilty to violating the Foreign Corrupt Practices Act by bribing government officials in Iraq and Indonesia. Innospec paid the bribes to secure the sale of its product and to exclude NewMarket’s product in Iraq and Indonesia. Afton Chemical Corporation and NewMarket Corporation are seeking treble damages, all reasonable attorneys’ fees, expenses, and costs for injuries sustained as a result of these bribes.

ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds

On July 31, 2008, our Board of Directors approved a share repurchase program that authorized management to repurchase up to $100 million of NewMarket Corporation’s outstanding common stock until December 31, 2010, as market conditions warrant and covenants under our existing agreements permitted. We could conduct the share repurchases in the open market and in privately negotiated transactions. The repurchase program did not require NewMarket to acquire any specific number of shares and could be terminated or suspended at any time. Approximately $780 thousand remained available under the authorization at June 30, 2010. The following table outlines the purchases during the second quarter 2010 under this authorization.

On July 21, 2010, our Board of Directors approved a new share repurchase program authorizing management to repurchase up to $200 million of NewMarket Corporation’s outstanding common stock until December 31, 2012, as market conditions warrant and covenants under our existing agreements permit. We may conduct the share repurchases in the open market and in privately negotiated transactions. The repurchase program does not require NewMarket to acquire any specific number of shares and may be terminated or suspended at any time. The 2008 repurchase program was terminated.
