Ladies and Gentlemen:

         Origen Financial, Inc., a Delaware corporation (the "Company"),
proposes, upon the terms and considerations set forth herein, to issue and sell
to you, as the initial purchaser (the "Initial Purchaser"), an aggregate of Six
Million Five Hundred Thousand (6,500,000) shares (the "Initial Shares") of its
common stock, par value $0.01 per share (the "Common Stock"). In addition, the
Company proposes, upon the terms and considerations set forth herein, to grant
the Initial Purchaser an option to purchase up to an additional Two Million Two
Hundred Fifty Thousand (2,250,000) shares of its Common Stock (the "Option
Shares" and, together with the Initial Shares, the "Shares"). The Shares will
have the rights and preferences that are summarized in the Offering Memorandum
(as defined below). This purchase agreement (this "Agreement") is to confirm the
agreement concerning the purchase of the Shares from the Company by the Initial
Purchaser.

         1. Preliminary Offering Memorandum and Offering Memorandum. The Shares
will be offered and sold to the Initial Purchaser without registration under the
Securities Act of 1933, as amended (the "Act"), in reliance on an exemption
pursuant to Section 4(2) under the Act. The Company has prepared a preliminary
offering memorandum, dated September 2, 2003 (the "Preliminary Offering
Memorandum"), and an offering memorandum, dated October 7, 2003 (the "Offering
Memorandum"), setting forth information regarding the Company and the Shares.
Any references herein to the Preliminary Offering Memorandum and the Offering
Memorandum shall be deemed to include all documents incorporated by reference
therein and all amendments and supplements thereto. The Company hereby confirms
that it has authorized the use of the Preliminary Offering Memorandum and the
Offering Memorandum in connection with the offering and resale of the Shares by
the Initial Purchaser.

         It is understood and acknowledged that upon original issuance thereof,
and until such time as the same is no longer required under the applicable
requirements of the Act, the Shares (and all securities issued in exchange
therefore or in substitution thereof) shall bear the following legend (along
with such other legends as the Initial Purchaser and its counsel deem
necessary):

         "THE SHARES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED
         STATES SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD,
         PLEDGED OR OTHERWISE

subsidiaries would have any liability that is intended to be qualified under
Section 401(a) of the Code is so qualified in all material respects and nothing
has occurred, whether by action or by failure to act, which would cause the loss

Offering Memorandum, as of its date, contains all the information specified in,
and meeting the requirements of Rule 144A(d)(4) under the Act.

that purpose has commenced or is pending, or to the knowledge of the Company, is
contemplated.

agreements, substantially in the form attached hereto as Exhibit E, from each of
the following persons and entities: (i) each officer of the Company, (ii) each
director of the Company and (iii) each purchaser listed on Exhibit A to the
Concurrent Private Placement Agreement by and among the Company and each of the
purchasers named therein (the "Concurrent Private Placement Agreement").

                  (m) Subsequent to the execution and delivery of this Agreement
there shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange, the Nasdaq National Market or the
American Stock Exchange or in the over-the-counter market, or trading in any
securities of the Company on any exchange or in the over-the-counter market, has
been suspended or minimum prices shall have been established on any such
exchange or such market by the Commission, by such exchange or by any other
regulatory body or governmental authority having jurisdiction; (ii) a material
disruption in securities settlement, payment or clearance services in the United
States; (iii) a banking moratorium has been declared by Federal or state
authorities; (iv) any attack on, outbreak or escalation of hostilities or act of

                                       18
<PAGE>

or international calamity, crisis or emergency if, in the judgment of the
Initial Purchaser, the effect of any such attack, outbreak, escalation, act,
declaration, calamity, crisis or emergency makes it impractical or inadvisable
to proceed with completion of the offering or sale of and payment for the
Shares; or (v) the occurrence of any other calamity, crisis (including without
limitation as a result of terrorist activities), or material adverse change in
general economic, political or financial conditions (or the effect of
international conditions on the financial markets in the United States shall be
such) as to make it, in the judgment of the Initial Purchaser, impracticable or
inadvisable to proceed with offering or delivery of the Shares being delivered
on the Closing Date or that, in the judgment of the Initial Purchaser, would
materially and adversely affect the financial markets or the market for the
Shares.

                  All opinions, letters, evidence and certificates mentioned
above or elsewhere in this Agreement shall be deemed to be in compliance with
the provisions hereof only if they are in form and substance reasonably
satisfactory to counsel for the Initial Purchaser.

         8. Indemnification and Contribution.

                  (a) The Company hereby agrees to indemnify and hold harmless
the Initial Purchaser, its directors, officers and employees and each person, if
any, who controls the Initial Purchaser within the meaning of the Act, from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof (including, but not limited to, any loss, claim, damage,
liability or action relating to purchases and sales of Shares), to which the
Initial Purchaser or any such director, officer, employee or controlling person
may become subject, under the Act, the Exchange Act, or other international,
federal or statutory law or regulation, or at common law, or otherwise, insofar
as such loss, claim, damage, liability or action arises out of, or is based
upon, (i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any Preliminary Offering Memorandum or the Offering Memorandum
or in any amendment or supplement thereto, (B) in any Blue Sky application or
other document prepared or executed by the Company (or based upon any written
information furnished by the Company) specifically for the purpose of qualifying
any or all of the Shares under the securities laws of any state or other
jurisdiction (any such application, document or information being hereinafter
called a "Blue Sky Application") or (C) in any materials or information provided
to investors by, or with the approval of, the Company in connection with the
marketing of the offering of the Shares ("Marketing Materials"), including any
roadshow or investor presentations made to investors by the Company (whether in
person or electronically), (ii) the omission or alleged omission to state in any
Preliminary Offering Memorandum or the Offering Memorandum, or in any amendment
or supplement thereto, or in any Blue Sky Application or in any Marketing
Materials, any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, (iii) any act or failure to act or any alleged act or
failure to act by the Initial Purchaser in connection with, or relating in any
manner to, the Shares or the offering contemplated hereby, and that is included
as part of or referred to in any loss, claim, damage, liability or action
arising out of or based upon matters covered by clause (i) or (ii) above
(provided that the Company shall not be liable under this clause (iii) to the
extent that it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be taken
by the Initial Purchaser through its gross negligence or willful misconduct),
(iv) any inaccuracy in the representations



                                       19
<PAGE>

and warranties of the Company contained in this Agreement; (v) any failure of
the Company to perform its obligations hereunder; or (vi) any claim or action
for rescission under the Act or any international, federal or state securities
laws to which the Initial Purchaser or any such director, officer, employee or
controlling person may become subject under the Act, the Exchange Act or other
international, federal or state statutory law or regulation or at common law or
otherwise in connection with the transactions contemplated hereby; and the
Company shall reimburse the Initial Purchaser and its directors, officers,
employees or controlling persons upon demand for any legal or other expenses
incurred by the Initial Purchaser and its directors, officers, employees or
controlling persons in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or
action as such expenses are incurred; provided, however, that the Company shall
not be liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of, or is based upon, any untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Offering Memorandum or Offering Memorandum, or in any such amendment or
supplement thereto, or in any Blue Sky Application or in any Marketing
Materials, in reliance upon and in conformity with written information
concerning the Initial Purchaser furnished to the Company through the Initial
Purchaser by or on behalf of the Initial Purchaser specifically for inclusion
therein. The foregoing indemnity agreement is in addition to any liability that
the Company may otherwise have to the Initial Purchaser or to any director,
officer, employee or controlling person of the Initial Purchaser.

                  (b) The Initial Purchaser hereby agrees to indemnify and hold
harmless the Company its officers and employees, each of its directors, and each
person, if any, who controls the Company within the meaning of the Act, from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company or any such director, officer, employee or
controlling person may become subject, under the Act or otherwise, insofar as
such loss, claim, damage, liability or action arises out of, or is based upon,
(i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any Preliminary Offering Memorandum or the Offering Memorandum
or in any amendment or supplement thereto, (B) in any Blue Sky Application, or
(C) in any Marketing Materials or (ii) the omission or alleged omission to state
in any Preliminary Offering Memorandum or the Offering Memorandum, or in any
amendment or supplement thereto, or in any Blue Sky Application or in any
Marketing Materials any material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under
which they were made, not misleading, but in each case only to the extent that
the untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with written information concerning
the Initial Purchaser furnished to the Company by or on behalf of the Initial
Purchaser specifically for inclusion therein, and the Initial Purchaser shall
reimburse the Company and any such director, officer, employee or controlling
person for any legal or other expenses reasonably incurred by the Company or any
such director, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability that the Initial Purchaser
may otherwise have to the Company or any such director, officer, employee or
controlling person.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in



                                       20
<PAGE>

respect thereof is to be made against the indemnifying party under this Section
8, notify the indemnifying party in writing of the claim or the commencement of
that action; provided, however, that the failure to notify the indemnifying
party shall not relieve it from any liability that it may have under this
Section 8 except to the extent it has been materially prejudiced by such failure
and; provided, further, that the failure to notify the indemnifying party shall
not relieve it from any liability that it may have to an indemnified party
otherwise than under this Section 8. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying party
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party. After notice from the indemnifying party
to the indemnified party of its election to assume the defense of such claim or
action, the indemnifying party shall not be liable to the indemnified party
under this Section 8 for any legal or other expenses subsequently incurred by
the indemnified party in connection with the defense thereof other than
reasonable costs of investigation; provided, however, that the Initial Purchaser
shall have the right to employ counsel to represent jointly the Initial
Purchaser and its directors, officers, employees and controlling persons who may
be subject to liability arising out of any claim in respect of which indemnity
may be sought by the Initial Purchaser against the Company under this Section 8
if the Initial Purchaser is advised by counsel that there exists one or more
legal defenses different than those available to the Company and in the
reasonable judgment of such counsel, it is advisable for the Initial Purchaser
and those directors, officers, employees and controlling persons to be jointly
represented by one separate counsel, and in that event the fees and expenses of
such separate counsel shall be paid by the Company. No indemnifying party shall
(i) without the prior written consent of the indemnified parties (which consent
shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment of the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

                  (d) If the indemnification provided for in this Section 8
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 8(a) or 8(b) in respect of any loss, claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company on the one hand and the Initial Purchaser on the other
from the offering of the Shares or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company, on the one hand, and the Initial
Purchaser on the other with respect to the acts, statements or omissions that
resulted in such loss, claim, damage or liability, or action in respect




                                       21
<PAGE>

thereof, as well as any other relevant equitable considerations. The relative
benefits received by the Company, on the one hand, and the Initial Purchaser on
the other with respect to such offering shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Shares purchased
under this Agreement (before deducting expenses) received by the Company on the
one hand, and the total discounts and commissions received by the Initial
Purchaser with respect to the Shares purchased under this Agreement, on the
other hand, bear to the total gross proceeds from the offering of the Shares
under this Agreement as set forth on the cover page of the Offering Memorandum.
The relative fault shall be determined by reference to whether the untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or the
Initial Purchaser, the intent of the parties and their relative knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Initial Purchaser agree that it would not be just
and equitable if contributions pursuant to this Section 8(d) were to be
determined by pro rata allocation or by any other method of allocation that does
not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8(d), the Initial Purchaser shall
not be required to contribute any amount in excess of the difference between the
amount the Initial Purchaser received in connection with sales of the Shares to
Eligible Purchasers and the amount the Initial Purchaser paid to the Company for
such Shares. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

                  (e) The Initial Purchaser confirms and the Company
acknowledges that the statements with respect to the offering of the Shares by
the Initial Purchaser set forth in the section entitled "Plan of Distribution"
in the Offering Memorandum are correct and constitute the only information
concerning such Initial Purchaser furnished in writing to the Company by or on
behalf of the Initial Purchaser specifically for inclusion in the Offering
Memorandum.

                  (f) The Company hereby acknowledges and agrees that any and
all claims for indemnification or contribution payment that are brought against
the Company by any party to the Contribution Agreement (other than Woodward
Holding, LLC with respect to those shares of Common Stock purchased under the
Concurrent Private Placement Agreement) will be subordinated in right of payment
to those claims for indemnification or contribution payment in connection with
the offering contemplated hereby that are brought against the Company by a
person who purchased Shares from the Initial Purchaser.

         9. Termination. The obligations of the Initial Purchaser hereunder may
be terminated by the Initial Purchaser by notice given to and received by the
Company prior to delivery of and payment for the Shares if, prior to that time,
any of the events described in Section 7(m) shall have occurred or if the
Initial Purchaser shall decline to purchase the Shares for any reason permitted
under this Agreement.



                                       22
<PAGE>

         10. Reimbursement of Initial Purchaser's Expenses. If the Company fails
to tender the Shares for delivery to the Initial Purchaser by reason of any
failure, refusal or inability on the part of the Company to perform any
agreement on its part to be performed, or because any other condition of the
obligations hereunder required to be fulfilled by the Company is not fulfilled,
the Company shall reimburse the Initial Purchaser for all reasonable
out-of-pocket expenses (including fees and disbursements of counsel) incurred by
the Initial Purchaser in connection with this Agreement and the proposed
purchase of the Shares, and upon demand the Company shall pay the full amount
thereof to the Initial Purchaser.

         11. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

                  (a) if to the Initial Purchaser, shall be delivered or sent by
