    HOUSTON--(BUSINESS WIRE)--May 3, 2006--NGP Capital Resources
Company (NASDAQ:NGPC):

    Update on Investment Activity

    NGP Capital Resources Company (NASDAQ:NGPC) today announced that
it has closed an $85 million Senior Secured Credit Facility (the
"Facility") and a $10 million Senior Subordinated Secured Convertible
Term Loan (the "Convertible Term Loan") with Resaca Exploitation, LP
("Resaca"), a private Houston, Texas based oil and gas producer
affiliated with Torch Energy Advisors Incorporated. NGPC acted as
arranger and agent for the Facility and the Convertible Term Loan and
has committed to fund 40% of each, with the remaining commitments
provided by other investors. Initial availability under the Facility
is approximately $76 million, with approximately $62 million funded;
an additional $10 million was made available and funded under the
Convertible Term Loan. NGPC's portion of the initial funding was $24.6
million under the Facility and $4.0 million under the Convertible Term
Loan.
    The Facility and the Convertible Term Loan are secured by first
and second liens, respectively, on substantially all of Resaca's
properties. Additionally, as partial consideration for providing the
Facility and Convertible Term Loan, NGPC received an overriding
royalty interest in Resaca's properties.
    Proceeds of the Facility and the Convertible Term Loan will be
used by Resaca to acquire and develop oil and gas assets located in
west Texas and New Mexico.
    Following this investment, NGPC currently has committed and made
available for funding an approximate total of $172 million to nine
portfolio companies, with approximately $147 million currently
