The Fund further represents and warrants that it has appropriate policies and procedures in place to ensure that such web site continuously complies with Rule 498.

5. The Fund and the Adviser each agrees that the URL indicated on each Summary Prospectus will lead Company contract owners ("Contract Owners") directly to the web page used for hosting Summary Prospectuses and that such web page will host the current Fund and series documents required to be posted in compliance with Rule 498. The Fund shall use its best efforts to promptly notify the Company of any unexpected interruptions in availability of this web page. The Fund and the Adviser each agrees that the web landing page used for hosting Summary Prospectuses will not contain any marketing materials.

At the Company's request, the Adviser and the Fund will provide the Company with URLs to the current Fund and series documents for use with Company's electronic delivery of Fund documents or on the Company's website. The Adviser and the fund will be responsible for ensuring the integrity of the URLs and for maintaining the Fund and series current documents on the website to which such URLs originally navigate.

10. The Company shall be permitted, but not required, in its sole discretion, to post a copy of the Fund's Statutory Prospectuses and/or Summary Prospectuses, statements of additional information, supplements, annual reports, and semi-annual reports on the Company's website.
