a.     Except for the obligations set forth in this Agreement, Morgan, on behalf of itself and each and every other person or entity claiming by or through it, does hereby unconditionally release and forever discharge ERI and any parent, subsidiary, representative, or related company from all claims, demands, losses, causes of action, costs, expenses, attorney’s fees, liabilities and indemnities of all and any nature whatsoever, under the law of any jurisdiction worldwide, whether known or unknown, suspected or unsuspected, whether concealed or hidden, that now exist or existed at any time previously, including, but not limited, to any and all claims that arise out of or are in any way based upon, connected with, or related to the claims asserted in the Lawsuit, including any right of appeal of the Judgment.

b.     Except for the obligations set forth in this Agreement, ERI, on behalf of itself and each and every other person or entity claiming by or through it, does hereby unconditionally release and forever discharge Morgan and any parent, subsidiary, representative, or related company from all claims, demands, losses, causes of action, costs, expenses, attorney’s fees, liabilities and indemnities of all and any nature whatsoever, under the law of any jurisdiction worldwide, whether known or unknown, suspected or unsuspected, whether concealed or hidden, which now exist or existed at any time previously, including, but not limited, to any and all claims that arise out of or are in any way based upon, connected with, or related to the claims asserted in the Lawsuit, including any right of appeal of the judgment.

d.     With respect to any and all of the claims encompassed by this Agreement, as described above, the Parties expressly waive and relinquish, to the fullest extent permitted by law, the provisions, rights, and benefits of section 1542 of the California Civil Code, which provides that:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

e.     The only exceptions to the Parties' mutual general release are the parties' respective obligations under this Agreement, which shall, upon execution of the Agreement, constitute the sole legal obligations of the Parties.

f.     No Party shall file a lawsuit or otherwise assert a claim that has been released by this Agreement.

4.     Time is of the essence with respect to ERI’s payment obligations pursuant to paragraph one. In the event Morgan does not receive wired funds in the amount of $1,700,000 by Friday May 8, 2015, then Morgan shall have the exclusive option to nullify this Agreement in its entirety.

5.     Confidentiality. The Parties agree that the terms of this Agreement shall be kept confidential and shall not be disclosed to any third party at any time, except as may be necessary by either Party to report to its accountants, attorneys, financial institutions, regulators, or as otherwise required by law, including in response to a lawful subpoena, as may be necessary to pursue any legal action in the event of breach of this Agreement, or as may be required in ERI’s public financial filings.

6.     Each Party represents and warrants it has the sole right and authority to execute this Agreement on its behalf and that it has not sold, assigned, transferred, conveyed, hypothecated, or otherwise disposed any right related to the Lawsuit or surrendered by this Agreement.

7..     Except as provided for in Paragraph 4, no provision of this Agreement may be released, amended, modified, or waived unless such amendment or modification is executed in writing and signed by all Parties.

8.     Each of the Parties has cooperated and participated in the drafting and preparation of this Agreement. Accordingly, all Parties acknowledge and agree that this Agreement shall not be construed or interpreted in favor of or against any of the Parties by virtue of the identity of its drafters or their respective contributions to this Agreement. Since both Parties have had an equal opportunity to negotiate and draft the terms of this Agreement, no liability shall be assumed by one Party or the other arising out of the drafting of this Agreement.

9.     This Agreement may be signed in more than one counterpart, each of which shall be deemed an original. This Agreement shall be deemed fully executed and effective when all Parties have executed at least one of the counterparts hereof, although no single counterpart bears all such signatures. Such counterparts shall, together, constitute one and the same instrument. Signature pages may be transmitted by facsimile and are effective as originals.

The Parties agree that no promises or inducements have been made other than those which are set forth in this Agreement.
