   Santa Fe Receivables Corporation (SFRC). SFRC transfers an undivided interest in such receivables,
   with limited exceptions, to a master trust and causes the trust to issue an undivided interest in
   the receivables to investors (the A/R sales program). The undivided interests in the master trust
   purchased by investors may be in the form of certificates or purchased interests. BNSF Railway
   retains the collection responsibility with respect to the accounts receivable transferred. The
   investors in the master trust have no recourse to BNSF Railway&amp;#8217;s other assets except for customary
   warranty and indemnity claims. Creditors of BNSF Railway have no recourse to the assets of the
   master trust or SFRC until after the creditors have been paid and SFRC and the master trust have
   been terminated.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;BNSF Railway&amp;#8217;s total capacity to sell undivided interests to investors under the A/R sales
   program was $700&amp;#160;million at June&amp;#160;30, 2010, which was comprised of two $175&amp;#160;million, 364-day
   accounts receivable facilities and two $175&amp;#160;million, 3-year accounts receivable facilities. In
   November&amp;#160;2009, BNSF Railway extended the commitment termination date of the two 364-day facilities
   to November&amp;#160;2010. The two 3-year facilities were entered into in November&amp;#160;2007 and have a
   commitment termination date in November&amp;#160;2010. Each of the financial institutions providing credit
   for the facilities is rated Aa3/A&amp;#043; or higher. The amount of undivided interests in the accounts
   receivable sold by BNSF Railway to investors fluctuates based on borrowing needs and upon the
   availability of receivables and is directly affected by changing business volumes and credit risks,
   which may, from time to time, reduce the effective capacity of the program to less than the $700
   million. Additionally, if the combined dilution and delinquency percentages exceed an established
   threshold, there would be an impact on the amount of undivided interest that BNSF Railway could
   sell. At June&amp;#160;30, 2010, the effective capacity under the A/R sales program was $700&amp;#160;million.
   &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;As discussed in Note 1 to the Consolidated Financial Statements, on January&amp;#160;1, 2010, BNSF
   Railway prospectively adopted authoritative accounting guidance which amended accounting guidance
   related to transfers of assets and VIEs. The amended guidance also eliminated the concept of a
   QSPE.
   &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 January&amp;#160;1, 2010, the A/R sales program master trust was considered a VIE as it does not
   retain sufficient equity to finance its activities without the support of BNSF Railway. BNSF
   Railway has a variable interest in the master trust as it absorbs any losses related to the
   receivables transferred in the event of default. BNSF Railway is the primary beneficiary of the VIE
   as it (1)&amp;#160;directs the amount of undivided interest in receivables sold to investors by the master
   trust, and thus holds the power to direct the activities of the master trust that most
   significantly impact performance and (2)&amp;#160;has the obligation to absorb the losses in the event of
   defaulted receivables, which could potentially be significant to the master trust. As the primary
   beneficiary of the master trust, BNSF Railway fully consolidated the master trust at January&amp;#160;1,
   2010. The consolidation did not impact the Company&amp;#8217;s consolidated financial statements as there
   were no outstanding undivided interests held by investors under the A/R sales program at January&amp;#160;1,
   2010. Prior to 2010, the A/R sales master trust was considered a QSPE and was not consolidated.
   &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;As of June&amp;#160;30, 2010 and December&amp;#160;31, 2009, there were no outstanding undivided interests held
   by investors under the A/R sales program; thus, no asset or related liability was recorded in the
   Company&amp;#8217;s Consolidated Balance Sheets. For the six months ended June&amp;#160;30, 2009, $50&amp;#160;million of cash
   flows related to the A/R sales program was classified as Operating Activities in the Consolidated
   Statement of Cash Flows. Upon adoption of the aforementioned guidance on January&amp;#160;1, 2010, any
   prospective activity will be classified as Financing Activities in the Consolidated Statements of
   Cash Flows. For the quarter ended June&amp;#160;30, 2010, there was no cash flow activity related to the A/R
   sales program.
   &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;BNSF Railway does not provide financial support to the master trust that it was not previously
   contractually obligated to provide.
   &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 June&amp;#160;30, 2010 and December&amp;#160;31, 2009, $12&amp;#160;million and $21&amp;#160;million, respectively, of accounts
   receivable were greater than 90&amp;#160;days old.
   &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;BNSF Railway maintains an allowance for bill adjustments and uncollectible accounts based upon
   the expected collectibility of accounts receivable, including receivables transferred to the master
   trust. At June&amp;#160;30, 2010, and December&amp;#160;31, 2009, $17&amp;#160;million and $31&amp;#160;million, respectively, of such
   allowances had been recorded.
