   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;8. VARIABLE INTEREST ENTITIES&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;On January&amp;#160;1, 2010, FirstEnergy adopted the amendments to the consolidation topic addressing VIEs.
   This standard requires that FirstEnergy and its subsidiaries perform a qualitative analysis to determine whether
   a variable interest gives FirstEnergy or its subsidiaries a controlling financial interest in a VIE. This analysis identifies
   the primary beneficiary of a VIE as the enterprise that has both the power to direct the activities of a VIE that most significantly
   impacts the entity&amp;#8217;s economic performance and the obligation to absorb losses of the entity that could potentially be significant
   to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. This standard also
   requires an ongoing reassessment of the primary beneficiary of a VIE and eliminates the quantitative approach previously required
   for determining whether an entity is the primary beneficiary. In order to evaluate contracts under the consolidation guidance,
   FirstEnergy aggregated contracts into categories based on similar risk characteristics and significance. The adoption of
   this new standard did not result in a change in the consolidation of VIEs by FirstEnergy or its subsidiaries.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy&amp;#8217;s consolidated financial statements include the accounts of entities in which it has a controlling financial interest.
   FirstEnergy consolidates certain VIEs in which it has financial control through disproportionate economics in its equity and debt
   investments in the entities. These VIEs include: FEV&amp;#8217;s joint venture in the Signal Peak mining and coal transportation operations;
   the PNBV and Shippingport bond trusts that were created to refinance debt originally issued in connection with sale and leaseback
   transactions; and wholly owned limited liability companies of JCP&amp;#038;L created to sell transition bonds to securitize the recovery of
   JCP&amp;#038;L&amp;#8217;s bondable stranded costs associated with the previously divested Oyster Creek Nuclear Generating Station, of which $310&amp;#160;million
   was outstanding as of December&amp;#160;31, 2010.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy and its subsidiaries reflect the portion of VIEs not owned by them in the caption noncontrolling interest within the
   consolidated financial statements. The change in noncontrolling interest on the Consolidated Balance Sheets is the result of net
   losses of the noncontrolling interests ($24&amp;#160;million) and distributions to owners ($5&amp;#160;million) during the year ended December&amp;#160;31, 2010.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%"&gt;&lt;i&gt;Mining Operations&lt;/i&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;On July&amp;#160;16, 2008, FEV entered into a joint venture with WMB Loan Ventures LLC and WMB Loan Ventures
   II LLC, to acquire a majority stake in the Signal Peak mining and coal transportation operations
   near Roundup, Montana. FEV made a $125&amp;#160;million equity investment in the joint venture, which
   acquired 80% of the mining operations (Signal Peak Energy, LLC) and 100% of the transportation
   operations, with FEV owning a 45% economic interest and an affiliate of WMB Loan Ventures LLC and
   WMB Loan Ventures II LLC owning a 55% economic interest in the joint venture. Both parties have a
   50% voting interest in the joint venture. FEV consolidates the mining and transportation operations
   of this joint venture in its financial statements. In March&amp;#160;2009, FEV agreed to pay a total of $8.5
   million to affiliates of WMB Loan Ventures LLC and WMB Loan Ventures II LLC to purchase an
   additional 5% economic interest in the Signal Peak mining and coal transportation operations.
   Voting interests remained unchanged after the sale was completed in July&amp;#160;2009. Effective August&amp;#160;21,
   2009, the joint venture acquired the remaining 20% stake in the mining operations by issuing a
   five-year note for $47.5&amp;#160;million. For both acquisitions, the difference between the consideration
   paid and the adjustment to the noncontrolling interest resulted in a charge to other paid in
   capital of approximately $30&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%"&gt;&lt;i&gt;Trusts&lt;/i&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy&amp;#8217;s consolidated financial statements include PNBV and Shippingport, VIEs created in 1996
   and 1997, respectively, to refinance debt originally issued in connection with sale and leaseback
   transactions. PNBV and Shippingport financial data are included in the consolidated financial
   statements of OE and CEI, respectively.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;PNBV was established to purchase a portion of the lease obligation bonds issued in connection with
   OE&amp;#8217;s 1987 sale and leaseback of its interests in the Perry Plant and Beaver Valley Unit 2. OE used
   debt and available funds to purchase the notes issued by PNBV for the purchase of lease obligation
   bonds. Ownership of PNBV includes a 3% equity interest by an unaffiliated third party and a 3%
   equity interest held by OES Ventures, a wholly owned subsidiary of OE. Shippingport was established
   to purchase all of the lease obligation bonds issued in connection with CEI&amp;#8217;s and TE&amp;#8217;s Bruce
   Mansfield Plant sale and leaseback transaction in 1987. CEI and TE used debt and available funds to
   purchase the notes issued by Shippingport.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%"&gt;&lt;i&gt;Power Purchase Agreements&lt;/i&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy subsidiaries JCPL, Met-Ed and Penelec have 21 long term power purchase agreements
   totaling 1,339 MW with NUG entities. The agreements were entered into pursuant to the Public
   Utility Regulatory Policies Act of 1978. FirstEnergy was not involved in the creation of, and has
   no equity or debt invested in, these entities. FirstEnergy evaluated these power purchase
   agreements to determine if certain NUG entities may be VIEs to the extent they own a plant that
   sells substantially all of its output to the Utilities and the contract price for power is
   correlated with the plant&amp;#8217;s variable costs of production.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy has determined that for all but two of these NUG entities, neither JCP&amp;#038;L, nor Met-Ed
   nor Penelec have variable interests in the entities or the entities are governmental or
   not-for-profit organizations that are not within the scope of consolidation consideration for VIEs.
   JCP&amp;#038;L may hold variable interests in the remaining two entities, which sell their output at
   variable prices that correlate to some extent with the operating costs of the plants. However,
   FirstEnergy applied the scope exception that exempts enterprises unable to obtain the necessary
   information to evaluate entities.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Since JCP&amp;#038;L has no equity or debt interests in the NUG entities, its maximum exposure to loss
   relates primarily to the above-market costs it incurs for power. FirstEnergy expects any
   above-market costs it incurs to be recovered from customers. Purchased power costs related to the
   two contracts that may contain a variable interest were $243&amp;#160;million and $225&amp;#160;million for the years
   ended December&amp;#160;31, 2010 and 2009, respectively.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%"&gt;&lt;i&gt;Loss Contingencies&lt;/i&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;FirstEnergy has variable interests in certain sale-leaseback transactions. FirstEnergy is not the
   primary beneficiary of these interests as it does not have control over the significant activities
   affecting the economics of the arrangement.

   upon the occurrence of certain contingent events that each company considers unlikely to occur. The
   maximum exposure under these provisions represents the net amount of casualty value payments due
   upon the occurrence of specified casualty events that render the applicable plant worthless. Net
   discounted lease payments would not be payable if the casualty loss payments were made. The
