None of the Parent Reports contained, at the time such Parent Report was filed, or if amended or restated, at such time when finally amended, restated or subsequently mailed to securityholders, any untrue statement of any material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

Neither the Parent nor any of its Subsidiaries has received, in writing, any material complaint, allegation, assertion or claim regarding the accounting or auditing practices, procedures, methodologies or methods of the Parent or any of its Subsidiaries or their respective internal accounting controls. To the Knowledge of the Parent, no attorney representing the Parent or its Subsidiaries has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by the Parent or any of its Subsidiaries or any of their respective officers, directors, employees or agents to the Board of Directors or any committee thereof pursuant to the rules of the SEC adopted under Section 307 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002.

(d) The Parent has (A) implemented and maintains (x) disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) designed to ensure that material information relating to the Parent and its Subsidiaries is made known on a timely basis to the management of the Parent and (y) a system of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) designed to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and (B) disclosed to the Parent’s outside auditors and the audit committee of the Board of Directors (x) all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Parent’s and its Subsidiaries’ ability to record, process, summarize and report financial data and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in the Parent’s internal control over financial reporting.

(e) There are no Liabilities of the Parent or its Subsidiaries of a nature (whether accrued, absolute, contingent or otherwise) other than: (i) Liabilities set forth in the consolidated balance sheet, including the notes thereto, of the Parent included in the most recent Parent Reports; (ii) Liabilities or obligations incurred in the ordinary course of business consistent with past practices since the date of such balance sheet; (iii) Liabilities under Contracts, none of which arise out of any breach, default or non-performance by the Parent or its Subsidiaries; and (iv) Liabilities disclosed on the Disclosure Schedules to this Agreement.

Section 2.9. Orders and Proceedings. There are no outstanding Orders to which the Parent or any of its Subsidiaries or any of their respective properties or assets is subject or bound that would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect and there are no Proceedings pending or, to the Knowledge of the Parent, threatened against the Parent or any of its Subsidiaries or to which any of their respective properties or assets is subject or bound that, if adversely determined, would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(b) The Parent and its Subsidiaries are not in breach or default under any of their contracts with Monaco and its Affiliates.

Section 2.11. Receivables. As of the date hereof, the amount due and owing from Oceanica and its Subsidiaries to the Parent and its Subsidiaries is as set forth on Schedule 2.11, which schedule sets forth the debtor, the creditor and that amount due.

Section 2.12. Anti-Corruption; Anti-Money Laundering.

(a) Neither the Parent nor the Company or any of their respective Subsidiaries, nor any director or officer of any of the Parent, the Company or their respective Subsidiaries, nor, to the Knowledge of the Parent, the Company, any stockholder, employee, vendor, sub-contractor or representative acting on behalf of any of the Parent, the Company and their Subsidiaries, has taken any action, directly or indirectly, that would result in a material violation of any Anti-Corruption Law, Anti-Money Laundering Law, or OFAC Law, whether within the United States of America or elsewhere.

Section 2.14. Offering. Assuming the accuracy of the Lender’s representations and warranties set forth in this Agreement, the issuance of Common Stock issuable upon conversion of the Note is exempt from the registration and prospectus requirements of the Securities Act, and any other applicable securities Law, and will be issued in compliance with all applicable federal and state securities and blue sky Laws. Neither the Parent, the Company nor any Person acting on their behalf will take any action hereafter that would cause the loss of such exemption.

Section 2.15. Anti-Takeover Provisions. The Parent has taken all actions necessary to render inapplicable to this Agreement and the Contemplated Transactions, and inapplicable to Lender and the Common Stock issuable upon conversion of the Note in connection with this Agreement and the Contemplated Transactions, any and all “fair price,” “moratorium,” “control share acquisition,” “business combination” and other similar statutes or regulations of any state or jurisdiction (collectively, “Takeover Laws”); and without limiting the foregoing, the Board of Directors has taken all actions necessary so that the restrictions on business combinations contained in Sections 78.378-78.3793 and 78.411-78.444 of the Nevada Revised Statutes, and, accordingly, any other section or any other Nevada Takeover Law or similar statute or regulation will not apply with respect to, or as a result of, the execution of this Agreement, the other Transaction Documents or the consummation of the Contemplated Transactions, without any further action on the part of the Stockholders or of the Board of Directors.

The Lender hereby represents and warrants to the Parent as of the date hereof that:

Section 3.1. Organization, Existence and Good Standing. Lender is duly organized and is validly existing and in good standing under the Laws pursuant to which it was formed, and has all requisite corporate power and corporate authority to carry on its businesses as now conducted and as presently proposed to be conducted. Lender is duly licensed or qualified to transact business as a foreign corporation or other equivalent entity and is in good standing in each jurisdiction in which the nature of the business transacted by it or the character of the properties owned or leased by it requires such licensing or qualification, except for those jurisdictions where the failure to be so licensed, qualified or in good standing would not reasonably be expected to have an Lender Material Adverse Effect.

Section 3.2. Authorization. Lender has full power and authority to execute and deliver this Agreement and the other Transaction Documents to which it is a party, and to carry out the provisions of this Agreement and the other Transaction Documents to which it is a party. Any and all corporate or partnership action on the part of Lender necessary for the authorization, execution and delivery of this Agreement and the performance of all obligations of Lender hereunder at each Closing has been, or will by each Closing have been, taken. This Agreement has been duly and validly executed and delivered and constitutes, and the Transaction Documents to which Lender is a party when executed and delivered will constitute, assuming due execution and delivery by the other parties thereto of this Agreement and the Transaction Documents, valid and legally binding obligations of Lender, enforceable against Lender in accordance with their respective terms, subject to the Enforceability Exceptions.

Section 3.3. Receipt of Information. Lender believes it has received all the information the Lender considers necessary or appropriate for deciding whether to purchase the Note. Lender further represents that Lender has had an opportunity to ask questions and receive answers from the Parent regarding the terms and conditions of the offering of the Note and the business, properties, prospects and financial condition of the Parent and to obtain additional information (to the extent the Parent possessed such information or could acquire it without unreasonable effort or expense) necessary to verify the accuracy of any information furnished to Lender or to which Lender had access. The foregoing, however, does not limit or modify the representations and warranties of the Parent and the Company in ARTICLE II of this Agreement or the right of Lender to rely thereon.

Section 3.4. Investment Experience. Lender confirms that it has such knowledge and experience in financial and business matters that Lender is capable of evaluating the merits and risks of an investment in the Note and of making an informed investment decision and understands that: this investment is suitable only for an investor which is able to bear the economic consequences of losing its entire investment; the purchase of the Note by the Lender hereunder is a speculative investment which involves a high degree of risk of loss of the entire

investment; there are substantial restrictions on the transferability of, and there will be no public market for, the Note, and accordingly, it may not be possible for the Lender to liquidate its investment in case of emergency; and this Agreement and the other Transaction Documents create a complex set of rights and obligations of the Lender.

Section 3.5. Qualifications of Lender. Lender is an “Accredited Lender” as such term is defined in Rule 501(a) under the Securities Act (without reliance on Rule 501(a)(4) thereof). The Lender will provide reasonable information requested by the Parent in connection with any filing required to be made with applicable securities regulators in connection with any issuance of Common Stock issuable upon conversion of the Note. Lender is not a “Bad Actor” within the meaning of Rule 506 of the Securities Act.

Section 3.6. Restricted Securities. Lender understands that no securities of the Parent may be sold, transferred, or otherwise disposed of without registration under the Securities Act or an exemption therefrom, and that in the absence of either an effective registration statement covering the Note or the Common Stock into which it may have been converted, as applicable, compliance with such distribution requirements or an available exemption from registration under the Securities Act, the Note or the Common Stock into which it may have been converted, as applicable, must be held indefinitely. Lender understands that the Note and the Common Stock into which it may have been converted will carry legends required by Law. In particular, the Lender is aware that the Note may not be sold pursuant to Rule 144 promulgated under the Securities Act unless all of the conditions of that rule are met.

The Parent shall reimburse Lender for its and its Affiliates’ reasonable, out-of-pocket fees, costs and expenses in an amount not to exceed $50,000 incurred in connection with the Contemplated Transaction through the increase in the principal amount of the Note by the amount of such fees, costs and expenses. All fees, costs and expenses incurred by the Parent in connection with this Agreement and the other Transaction Documents and the Contemplated Transactions shall be borne by Parent whether or not the Contemplated Transactions are consummated.

Section 4.5. Publicity and Reports. Each party agrees that, except as otherwise required by Law, it will not issue any reports, statements or releases, in each case relating to the Contemplated Transactions, without the prior written consent of the other parties hereto, which consent shall not unreasonably be withheld or delayed.

A waiver given by a party will be applicable only to the specific instance for which it is given.

Section 4.7. Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Neither this Agreement, nor any right, duty or obligation of any party hereunder, may be assigned or delegated by the Parent without the prior written consent of Lender.

Delaware (the “Designated Court”). Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the Designated Court and agrees that it will not bring any action whether in tort, contract, common or statutory law, equity or otherwise arising out of or relating to this Agreement or any other Transaction Document or any of the Contemplated Transactions or the subject matter hereof or thereof in any court other than the Designated Court.

EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY DISPUTE IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY DISPUTE.

Section 4.14. Specific Performance. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the parties shall be entitled to specific performance of the terms hereof, this being in addition to any other remedy to which they are entitled at law or in equity. The parties acknowledge that the awarding of equitable remedies is within the discretion of the applicable court.

Section 4.15. Remedies Cumulative. The rights and remedies of the parties are cumulative and not alternative.

Section 4.18. Severability.

(a) If any provision of this Agreement or any other Transaction Document is determined to be invalid, illegal or unenforceable, the remaining provisions of this Agreement and the other Transaction Documents shall remain in full force, if the essential terms and conditions of this Agreement and the other Transaction Documents for each party remain valid, binding and enforceable. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

(b) Any provision of this Agreement or any other Transaction Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
