   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;NOTE 11. FINANCIAL INSTRUMENTS&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&lt;b&gt;Fair Value of Financial Instruments&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Our financial instruments include cash and short-term investments, noncurrent investments in
   auction rate securities, accounts receivable, accounts payable, debt, foreign currency forward
   contracts, foreign currency option contracts and interest rate swaps. Except as described below,
   the estimated fair value of such financial instruments at December&amp;#160;31, 2009 and 2008 approximates
   their carrying value as reflected in our consolidated balance sheets. The fair value of our debt,
   foreign currency forward contracts and interest rate swaps has been estimated based on quoted year
   end market prices.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The estimated fair value of total debt at December&amp;#160;31, 2009 and 2008 was $2,126&amp;#160;million and
   $2,471&amp;#160;million, respectively, which differs from the carrying amounts of $1,800&amp;#160;million and $2,333
   million, respectively, included in our consolidated balance sheets.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;Foreign Currency Forward Contracts&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We conduct our business in over 90 countries around the world, and we are exposed to market
   risks resulting from fluctuations in foreign currency exchange rates. A number of our significant
   foreign subsidiaries have designated the local currency as their functional currency. We transact
   in various foreign currencies and have established a program that primarily utilizes foreign
   currency forward contracts to reduce the risks associated with the effects of certain foreign
   currency exposures. Under this program, our strategy is to have gains or losses on the foreign
   currency forward contracts mitigate the foreign currency transaction gains or losses to the extent
   practical. These foreign currency exposures typically arise from changes in the value of assets
   and liabilities which are denominated in currencies other than the functional currency. Our
   foreign currency forward contracts generally settle within 90&amp;#160;days. We do not use these forward
   contracts for trading or speculative purposes. We designate these forward contracts as fair value
   hedging instruments pursuant to ASC 815&lt;i&gt;, Derivatives and Hedging&lt;/i&gt;. Accordingly, we record the fair
   value of these contracts as of the end of our reporting period to our consolidated balance sheet
   with changes in fair value recorded in our consolidated statement of operations along with the
   change in fair value of the hedged item.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;At December&amp;#160;31, 2009 and 2008, we had outstanding foreign currency forward contracts with
   notional amounts aggregating $153&amp;#160;million and $125&amp;#160;million, respectively, to hedge exposure to
   currency fluctuations in various foreign currencies. These contracts are designated and qualify as
   fair value hedging instruments. The fair value was determined using a model with Level 2 inputs
   including quoted market prices for contracts with similar terms and maturity dates.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;Interest Rate Swaps&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We are subject to interest rate risk on our debt and investment of cash and cash equivalents
   arising in the normal course of our business, as we do not engage in speculative trading
   strategies. We maintain an interest rate management strategy, which primarily uses a mix of fixed
   and variable rate debt that is intended to mitigate the exposure to changes in interest rates in
   the aggregate for our investment portfolio. In addition, we are currently using interest rate
   swaps to manage the economic effect of fixed rate obligations associated with our senior notes so
   that the interest payable on the senior notes effectively becomes linked to variable rates.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2009, we entered into two interest rate swap agreements (&amp;#8220;the Swap Agreements&amp;#8221;) for a
   notional amount of $250&amp;#160;million each in order to hedge changes in the fair market value of our $500
   million 6.5% senior notes maturing on November&amp;#160;15, 2013. Under the Swap Agreements, we receive
   interest at a fixed rate of 6.5% and pay interest at a floating rate of one-month Libor plus a
   spread of 3.67% on one swap and three-month Libor plus a spread of 3.54% on the second swap both
   through November&amp;#160;15, 2013. The counterparties are primarily the lenders in our credit facilities.
   The Swap Agreements are designated and each qualifies as a fair value hedging instrument. The swap
   to three-month Libor is deemed to be 100&amp;#160;percent effective resulting in no gain or loss recorded in
   the
   consolidated statement of operations. The effectiveness of the swap to one-month Libor, which is
       highly effective, is calculated as of each period end and any ineffective portion is recognized in
       the consolidated statement of operations. The fair value of the Swap Agreements was determined
       using a model with Level 2 inputs including quoted market prices for contracts with similar terms
       and maturity dates.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;Fair Value of Derivative Instruments&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The fair value of derivative instruments included in our consolidated balance sheet was as

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We sell our products and services to numerous companies in the oil and natural gas industry.
   Although this concentration could affect our overall exposure to credit risk, we believe that our
       risk is minimized since the majority of our business is conducted with major companies within the
       industry. We perform periodic credit evaluations of our customers&amp;#8217; financial condition and
       generally do not require collateral for our accounts receivable. In some cases, we will require
       payment in advance or security in the form of a letter of credit or bank guarantee.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We maintain cash deposits with financial institutions that may exceed federally insured
       limits. We monitor the credit ratings and our concentration of risk with these financial
       institutions on a continuing basis to safeguard our cash deposits.
