Under the Private Securities Litigation Reform Act of 1995

This document may contain or incorporate by reference forward-looking statements as defined under the federal securities laws
regarding DCP Midstream Partners, LP, including projections, estimates, forecasts, plans and objectives. Although management
believes that expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such
expectations will prove to be correct. In addition, these statements are subject to certain risks, uncertainties and other
assumptions that are difficult to predict and may be beyond our control. If one or more of these risks or uncertainties materialize,
or if underlying assumptions prove incorrect, the Partnership’s actual results may vary materially from what management
anticipated, estimated, projected or expected. Among the key risk factors that may have a direct bearing on the Partnership’s
results of operations and financial condition are:

the level and success of natural gas drilling around our assets and our ability to connect supplies to our
gathering and processing systems in light of competition;

our ability to grow through acquisitions, asset contributions from our parents, or organic growth projects,
and the successful integration and future performance of such assets;

our ability to access the debt and equity markets;

fluctuations in oil, natural gas, propane and other NGL prices;

our ability to purchase propane from our principal suppliers for our wholesale propane logistics business; and

the credit worthiness of counterparties to our transactions.

Investors are encouraged to closely consider the disclosures and risk factors contained in the Partnership’s annual and quarterly
reports filed from time to time with the Securities and Exchange Commission. The Partnership undertakes no obligation to
publicly update or revise any forward-looking statements, whether as a result of new information, future events or
otherwise. Information contained in this document is unaudited, and is subject to change.
