ARTICLE TWO. AMENDMENTS

SECTION 201. Amendment to Section 1014(a). Section 1014(a) of the Indenture shall be deleted in its entirety and substituted with the following therefor:

“Notwithstanding that DDi Capital may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, DDi Capital will, within 15 days after DDi Capital is or would be required to file the same with the SEC, provide the Trustee and the holders of the Senior Notes with the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Section 13 or 15(d) of the Exchange Act as if DDi Capital were subject to the reporting requirements of Section 13 and 15(d) of the Exchange Act, provided, that such reports need not be audited by an independent certified public accountant so long as the chief financial officers of DDi Capital and DDi Corp. certify such reports and such reports otherwise satisfy the reporting requirements of Section 13 or 15(d) of the Exchange Act. Without limiting the foregoing, so long as any Senior Notes are outstanding, DDI Capital shall furnish to the holders of the Senior Notes (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if DDI Capital were required to file such form (but excluding any audit information required to be provided by independent certified public accountants so long as the chief financial officers of DDi Capital and DDi Corp. certify such information and such information otherwise complies with the requirements of Forms 10-Q and 10-K, as applicable) and (ii) such other reports containing substantially the same information required to be contained in a Form 8-K, in each case within 15 days of the end of the applicable period.”
