a condensed format, it does not include all the disclosures required by U.S. GAAP, and should be
read along with our 2010 Annual Report on Form 10-K. The financial statements as of March 31, 2011,

balance sheet as of December 31, 2010, was derived from the audited balance sheet filed in our 2010
Annual Report on Form 10-K. In our opinion, we have made adjustments, all of which are of a normal,
recurring nature to fairly present our interim period results. Due to the seasonal nature of our

</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Acquisition of Additional Interest in SNG. </i>In March 2011, we acquired an additional 25 percent
general partner interest in SNG from El Paso for $667 million in cash. We financed the acquisition
through (i) net proceeds of $467 million from our March 2011 public offering of common units
and related issuance of general partner units to El Paso (see Note 3) and (ii) $200 million
borrowings under our revolving credit facility (see Note 5). This transaction was for the
acquisition of an additional noncontrolling interest in an already consolidated entity, thus was
accounted for on a prospective basis. Accordingly, we have decreased our historical noncontrolling
interest by $416 million associated with SNG and reflected the amount as an increase to general
partner’s capital. We have reflected El Paso’s 15 percent general partner interest in SNG as a
noncontrolling interest in our financial statements effective March 14, 2011. Subsequent to our
November 2010 acquisition of an additional 15 percent general partner interest in SNG, as disclosed
in our 2010 Annual Report on Form 10-K, we had the ability to control SNG’s operating and financial
decisions and policies, thus consolidated SNG in our financial statements. We retrospectively
adjusted our historical financial statements to reflect the reorganization of entities under common
control and the change in reporting entity. As a result of the retrospective consolidation,
pre-acquisition earnings of the incremental interest in SNG in historical periods have been
allocated solely to our general partner. In addition, the retrospective consolidation of SNG
increased net income attributable to EPB by $27 million for the quarter ended March 31, 2010. We
reflected El Paso’s 40 percent general partner interest in SNG as a noncontrolling interest in our
financial statements for the quarter ended March 31, 2010 and for the period of January 1, 2011 to
March 13, 2011.

<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Acquisition of SLNG and Elba Express. </i>In March 2010, we acquired a 51 percent member interest
in each of SLNG and Elba Express from El Paso for $810 million. The consideration paid to El Paso
consisted of $658 million in cash and the issuance of common units and general partner units (see
Note 3). We financed the $658 million cash payment through (i) net proceeds of $420 million from
the issuance of public debt in March 2010, (ii) $236 million cash on hand from the proceeds of our
January 2010 public offering of common units and related issuance of general partner units to El
Paso (see Note 3) and (iii) $2 million borrowings under our revolving credit facility. We recorded
the additional interests in SLNG and Elba Express at their historical cost of $468 million and the
excess cash paid to El Paso of $190 million over contributed book value as a decrease to general
partners’ capital. Subsequent to the acquisition, we had the ability to control SLNG’s and Elba
Express’ operating and financial decisions and policies thus consolidated SLNG and Elba Express in
our financial statements. As a result of the retrospective consolidation, earnings prior to the
March 2010 acquisition have been allocated solely to our general partner. We reflected
El Paso’s 49 percent member interest in each of SLNG and Elba Express as noncontrolling interests
in our financial statements until the acquisition of the remaining 49 percent member interest in
each of SLNG and Elba Express in November 2010.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Other. </i>During the first quarter of 2010 and prior to our acquisition, Elba Express purchased
pipeline assets from SNG, its affiliate, for $8 million and sold pipeline assets to SNG for $18
million. We recorded both the purchase and sale at their historical cost and accordingly,
recognized no gain or loss on these transactions.

</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Earnings per unit. </i>Earnings per unit is calculated based on actual distributions made to our
unitholders, including the holders of IDRs, for the related reporting period. To the extent net
income attributable to EPB exceeds cash distributions, the excess is allocated to unitholders based
on their contractual participation rights to share in those earnings. If cash distributions exceed
net income attributable to EPB, the excess distributions are allocated proportionately to all
participating units outstanding based on their respective ownership percentages. Additionally, the
calculation of earnings per unit does not reflect an allocation of undistributed earnings to the
IDR holders beyond amounts distributable under the terms of the partnership agreement. Payments
made to our unitholders are determined in relation to actual declared distributions and are not
based on the net income allocations used in the calculation of earnings per unit.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     We have retrospectively adjusted our historical financial statements as discussed in our 2010
Annual Report on Form 10-K for the consolidation of SLNG, Elba Express and SNG following the
acquisition of controlling interests in each entity. As a result of the retrospective
consolidations, earnings prior to the acquisition of controlling interests (pre-acquisition
earnings) in SLNG, Elba Express and SNG have been allocated solely to our general partner in all
periods presented.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     Net income attributable to EPB per limited partner unit is computed by dividing the limited
partners’ interest in net income attributable to EPB by the weighted average number of limited
partner units outstanding. Diluted earnings per limited partner unit reflects the potential
dilution that could occur if securities or other agreements to issue common units were exercised,
settled or converted into common units. For the quarters ended March 31, 2011 and 2010, the
dilutive, restricted units outstanding were immaterial.

however, that new information or future developments could require us to reassess our potential

quality and pollution control. These laws and regulations require us to remove or remedy the effect
of the disposal or release of specified substances at current and former operating sites. At March
31, 2011, our accrual was approximately $10 million for environmental matters. Our accrual includes
amounts for expected remediation costs and associated onsite, offsite and groundwater technical
studies and related environmental legal costs.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     Our estimates of potential liability range from approximately $10 million to approximately $33
million. Our recorded environmental liabilities reflect our current estimates of amounts we will
expend on remediation projects in various stages of completion. However, depending on the stage of
completion or assessment, the ultimate extent of contamination or remediation required may not be
known. As additional assessments occur or remediation efforts continue, we may incur additional
liabilities.

<div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Superfund Matters. </i>Included in our recorded environmental liabilities are projects where we
have received notice that we have been designated or could be designated, as a Potentially
Responsible Party (PRP) under the Comprehensive Environmental Response, Compensation and Liability
Act (CERCLA), commonly known as Superfund, or state equivalents for one active site. Liability
under the federal CERCLA statute may be joint and several, meaning that we could be required to pay
in excess of our pro rata share of remediation costs. We consider the financial strength of other
PRPs in estimating our liabilities. Accruals for these issues are included in the previously
indicated estimates for Superfund sites.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     For 2011, we estimate that our total remediation expenditures will be approximately $2
million, most of which will be expended under government directed clean-up plans. In addition, we
expect to make capital expenditures for environmental matters of approximately $9 million in the
aggregate for the remainder of 2011 through 2015, including capital expenditures associated with
the impact of the Environmental Protection Agency rule on emissions of hazardous air pollutants
from reciprocating internal combustion engines which are subject to regulations with which we have
to be in compliance by October 2013.

potential exposure related to environmental matters. We may incur significant costs and liabilities
in order to comply with existing environmental laws and regulations. It is also possible that other
developments, such as increasingly strict environmental laws, regulations and orders of regulatory
agencies, as well as claims for damages to property and the environment or injuries to employees
and other persons resulting from our current or past operations, could result in substantial costs
and liabilities in the future. As this information becomes available, or other relevant
developments occur, we will adjust our accrual amounts accordingly. While there are still
uncertainties related to the ultimate costs we may incur, based upon our evaluation and experience
to date, we believe our reserves are adequate.

<div align="left" style="font-size: 10pt; margin-top: 6pt">     We participate in accounts receivable sales programs where we sell receivables in their
entirety to a third party financial institution (through wholly-owned special purpose entities).
The sale of these accounts receivable (which are short-term assets that generally settle within 60
days) qualify for sale accounting. The third party financial institution involved in these accounts
receivable sales programs acquires interests in various financial assets and issues commercial
paper to fund those acquisitions. We do not consolidate the third party financial institution
because we do not have the power to control, direct, or exert significant influence over its
overall activities since our receivables do not comprise a significant portion of its operations.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     In connection with our accounts receivable sales, we receive a portion of the sales proceeds
up front and receive an additional amount upon the collection of the underlying receivables (which
we refer to as a deferred purchase price). Our ability to recover the deferred purchase price is
based solely on the collection of the underlying receivables. The table below contains information
