h. Further Assurances. Each Party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other Party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

i. No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any Party.

j. Remedies. The Parties each acknowledge that a breach by any of them of their respective obligations hereunder will cause irreparable harm to the other Parties by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, each of the foregoing Parties acknowledges that the remedy at law for a breach of its obligations under this Agreement will be inadequate and agrees, in the event of a breach or threatened breach by any of such Parties of the provisions of this Agreement, that the harmed Party shall be entitled, in addition to all other available remedies at law or in equity, to an injunction or injunctions restraining, preventing or curing any breach of this Agreement and to enforce specifically the terms and provisions hereof, without the necessity of showing economic loss and without any bond or other security being required.

k. Obligations Several Not Joint. The obligations of each Investor under this Agreement are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under this Agreement. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional Party in any proceeding for such purpose. Each Investor has been represented by, or has had the opportunity to be represented by, its own separate legal counsel in its review and negotiation of all of the Documents.

l. Counterparts; Signatures by Facsimile. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which shall constitute one and the same agreement and shall become effective when counterparts have been signed by each Party and delivered to the other Party. This Agreement, once executed by a Party, may be delivered to the other Party hereto by facsimile transmission of a copy of this Agreement bearing the signature of the Party so delivering this Agreement and such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof..
