Item 1.01. Entry into a Material Definitive Agreement.
           ------------------------------------------

      On January 18, 2008, Chimera Investment Corporation (the "Company"),
entered into a master repurchase agreement (the "Agreement") with Credit Suisse
First Boston Mortgage Capital LLC ("CSFB"), an affiliate of Credit Suisse, one
of the underwriters of the Company's November 2007 initial public offering. This
type of lending arrangement is often referred to as a "repurchase facility."

      The Agreement is a $500 million lending facility of which $200 million is
on an uncommitted basis, which means CSFB must agree to each mortgage loan
financed under the Agreement in excess of $300 million outstanding at any given
time. The Agreement is set to terminate on January 16, 2009. Under the
Agreement, the Company will sell mortgage loans to CSFB for a purchase price
equal to the lesser of either the product of the market value of the purchased
mortgage loans to be sold multiplied by varying percentages of the purchase
price depending on the type of mortgage loan being financed, or the outstanding
principal amount thereof. In general, the price at which the Company will
repurchase the mortgage loans from CSFB will equal the original purchase price
plus accrued but unpaid interest. Pursuant to the terms of the agreement, the
Company will pay interest to CSFB ranging from LIBOR plus a number of basis
points depending on the type of mortgage loan being financed. The Company is
required to maintain certain routine covenants, in addition to standard
representations and warranties, during the term of the Agreement. The Agreement
is filed as Exhibit 10.1 to this Current Report and is incorporated herein by
reference.
