    I have reviewed this annual report on Form 10-K of Origen Financial, Inc.;2.
    
    Based on my knowledge, this report does not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this
report;3.
    
    Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material
respects the financial condition, results of operations and cash flows of
the registrant as of, and for, the periods presented in this report;4.
    
    The registrants other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over
financial reporting (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the registrant and have:
 a)
    
    Designed such disclosure controls and procedures, or caused such
disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the
registrant, including its consolidated subsidiaries, is made
known to us by others within those entities, particularly during
the period in which this report is being prepared;b)
    
    Designed such internal control over financial reporting, or
caused such internal control over financial reporting to be
designed under our supervision, to provide reasonable assurance
regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in
accordance with generally accepted accounting principles;c)
    
    Evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in this report our
conclusions about the effectiveness of the disclosure controls
and procedures, as of the end of the period covered by this
report based on such evaluation; andd)
    
    Disclosed in this report any change in the registrants internal
control over financial reporting that occurred during the

fiscal quarter in the case of an annual report) that has
materially affected, or is reasonably likely to materially
affect, the registrants internal control over financial
reporting; and
 5.
    
    The registrants other certifying officer and I have disclosed, based on
our most recent evaluation of internal control over financial
reporting, to the registrants auditors and the audit committee of registrants board of
directors (or persons performing the equivalent function):
 a)
    
    All significant deficiencies and material weaknesses in the
design or operation of internal control over financial reporting
which are reasonably likely to adversely affect the registrants
ability to record, process, summarize and report financial information; andb)
    
    Any fraud, whether or not material, that involves management or
other employees who have a significant role in the registrants
internal control over financial reporting.
