commitment or obligation to which it is a party or by which it is bound or (iii) materially violate any Law applicable to it or its business. 4.05 Licenses and Permits. As of the Effective Date, PHLVIC has, and during the term of this Agreement shall use reasonable efforts to maintain all material licenses, permits, registrations, authorizations, orders, consents, and other approvals by each Government Entity necessary or advisable for the performance of its obligations under the Transaction Documents to which it is a party. 4.06 Compliance with Law. As of the Effective Date, PHLVIC shall use reasonable efforts to conduct and will continue to conduct business operations in connection with performance of its duties and obligations under the Transaction Documents to which it is a party in compliance in all material respects with applicable Law. 4.07 Equipment, Facilities and Staff. PHLVIC has the equipment, facilities, systems, staff and assets necessary to perform its duties and obligations under the Transaction Documents to which it is a party. 4.08 Pending Litigation and Actions. PHLVIC is not subject to any current or pending litigation or regulatory actions that would materially impair its ability to carry out its duties and obligations under the Transaction Documents to which it is a party. 4.09 Registration Statement and Prospectus. The Registration Statement, on the date of which it was declared effective, did not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made (it being understood that no representation is made with respect to information about ICAS or ICC provided by ICAS or ICC in writing to PHL Variable). All statements in the Registration Statement, on the date of which it was declared - 8 - effective, relating to taxation and tax effects are true in all material respects. The Prospectus or other information contained in the Registration Statement, when disseminated or used after the effective date of the Registration Statement, shall not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made (it being understood that no representation is made with respect to information about ICAS or ICC provided by ICAS or ICC in writing to PHL Variable). PHLVIC shall immediately notify ICC in the event PHLVIC believes or has reason to believe that the representations and warranties in this paragraph are no longer true or completely accurate. 4.10 Tax Matters. It is more likely than not that: (1) PHLVIC will not be treated as the owner of the assets in an ICC Account for federal income tax purposes; (2) the GIE, including each Certificate, will be treated as an annuity contract for federal income tax purposes; however, if the value of an ICC Account happens to be greater than zero when an Owner's life expectancy is less than one year (which will only occur at extremely advanced ages), it is possible that the Policy could be treated as no longer constituting an annuity contract for Federal tax purposes from that point on; (3) for all Certificate Holders on the date of GIE issuance and during the entire period during which the GIE and each Certificate is in effect, losses with respect to the ICC Account will be deductible under Section 165(a) of the IRC notwithstanding the existence of the GIE' conditional guarantee of annual lifetime income payments in the event that the value of the assets in an ICC Account decreases to zero; (4) for all Certificate Owners on the date of GIE issuance and during the entire period during which the GIE and each Certificate is in effect, dividends on stock held in an ICC Account otherwise meeting the requirements of Section 1(h)(11) of the IRC will constitute qualified dividend income notwithstanding the existence of a GIE and its conditional guarantee of annual lifetime income payments in the event the value of the assets in the ICC Account decreases to zero; and (5) for each Certificate Owner on the date of Certificate issuance and during the entire period during which the GIE and each Certificate is in effect, the Certificate and assets in the ICC Account subject thereto will not be treated as a straddle under Section 1092 of the IRC. 4.11 Ownership of GIE; No Claims Relating to GIE.
