Section 1 - Registrant's Business and Operations

Item 1.01.      Entry into a Material Definitive Agreement.

     On August 31, 2006, NGP Capital Resources Company,  a Maryland  corporation
(the "Company"), entered into an Amended and Restated Revolving Credit Agreement
(the  "Investment  Credit  Agreement") and a Treasury  Secured  Revolving Credit
Agreement  (the "Treasury  Credit  Agreement"),  among the Company,  the lenders
party  thereto and SunTrust  Bank, as  administrative  agent for the lenders for
both credit agreements.

     Under the Investment  Credit  Agreement,  the lenders have agreed to extend
revolving  credit to the Company in an amount not to exceed  $80,000,000,  which
includes a $10,000,000 letter of credit  subfacility;  however,  the Company has
the  ability  to  increase  the credit  available  under the  Investment  Credit
Agreement  to an  amount  not to exceed  $175,000,000  by  obtaining  additional
commitments  from  existing  lenders  or  new  lenders.  The  Investment  Credit
Agreement has a three year term and bears interest,  at the Company's option, at
either (i) LIBOR plus 125 to 225 basis  points,  based on the degree of leverage
of the  Company or (ii) the base rate plus 25 to 75 basis  points,  based on the
degree of leverage of the Company. Proceeds from the Investment Credit Agreement
will be used to  supplement  the  Company's  equity  capital  to make  portfolio
investments.

     The  obligations  under the  Investment  Credit  Agreement  are  secured by
substantially all of the Company's assets, except certain assets that secure the
Treasury  Credit  Agreement,  and are  guarantied by the Company's  existing and
future  subsidiaries,  other than special purpose subsidiaries and certain other
subsidiaries. The Investment Credit Agreement contains affirmative and reporting
covenants and certain financial ratio and restrictive covenants,  including: (a)
maintaining  a ratio of net  asset  value  to  consolidated  total  indebtedness
(excluding net hedging liabilities) of the Company and its subsidiaries,  of not
less than 2.25:1.0,  (b)  maintaining a ratio of net asset value to consolidated
total  indebtedness  (including net hedging  liabilities) of the Company and its
subsidiaries,  of not less than 2.0:1.0,  (c)  maintaining a ratio of net income
(excluding  revenue from collateral  under the Treasury  Credit  Agreement) plus
interest,  taxes,  depreciation and amortization expenses ("EBITDA") to interest
expense (excluding interest on loans under the Treasury Credit Agreement) of the
Company  and its  subsidiaries  of not less than  3.0:1.0,  (d)  limitations  on
additional  indebtedness,  (e) limitations on liens,  (f) limitations on mergers
and other fundamental changes, (g) limitations on dividends,  (h) limitations on
disposition  of  assets  other  than  in the  normal  course  of  business,  (i)
limitations on transactions with affiliates,  (j) limitations on agreements that
prohibit liens on properties of the Company and its subsidiary  guarantors,  (k)
limitations on sale and leaseback  transactions,  (l) limitations on speculative
hedging  transactions,  and (m) limitations on the aggregate  amount of unfunded
commitments.

     Under the  Treasury  Credit  Agreement,  the lenders  have agreed to extend
revolving  credit loans to the Company in an amount not to exceed  $100,000,000.
Proceeds  from the Treasury  Credit  Agreement  will be used to  facilitate  the
growth of the  Company's  investment  portfolio and provide  flexibility  in the
sizing of its portfolio  investments.  The Treasury Credit Agreement has a three
year term and bears interest,  at the Company's option, at either (i) LIBOR plus
25 basis points or (ii) the base rate.  Prepayments  of loans under the Treasury
Credit Agreement made during the first year are subject to a premium equal to 1%
of the amount so prepaid.



     The obligations  under the Treasury Credit Agreement are secured by certain
securities  accounts  assets and are  guarantied by the  Company's  existing and
future  subsidiaries,  other than special purpose subsidiaries and certain other
subsidiaries.  The Treasury Credit Agreement contains  affirmative and reporting
covenants and certain financial ratio and restrictive covenants,  including: (a)
maintaining  a ratio of net  asset  value  to  consolidated  total  indebtedness
(excluding net hedging liabilities) of the Company and its subsidiaries,  of not
less than 2.25:1.0,  (b)  maintaining a ratio of net asset value to consolidated
total  indebtedness  (including net hedging  liabilities) of the Company and its
subsidiaries,  of not less  than  2.0:1.0,  (c)  maintaining  a ratio of  EBITDA
(excluding revenue from cash collateral) to interest expense (excluding interest
on  loans  under  the  Treasury  Credit   Agreement)  of  the  Company  and  its
subsidiaries of not less than 3.0:1.0,  (d) maintaining a ratio of collateral to
the aggregate  principal  amount of loans under the Treasury Credit Agreement of
not  less  than  1.01:1.0;  (e)  limitations  on  additional  indebtedness,  (f)
limitations on liens, (g) limitations on mergers and other fundamental  changes,
(h)  limitations  on dividends,  (i)  limitations on disposition of assets other
than in the normal course of business,  (j)  limitations  on  transactions  with
affiliates,  (k)  limitations on agreements that prohibit liens on properties of
the Company and its subsidiary guarantors, (l) limitations on sale and leaseback
transactions,  (m)  limitations on  speculative  hedging  transactions,  and (n)
limitations on the aggregate amount of unfunded commitments.

     The Company has  borrowed  $100,000,000  as of  September 1, 2006 under the
Treasury  Credit  Agreement.  From time to time,  certain of the lenders provide
customary commercial and investment banking services to the Company.
