                       LIMITED LIABILITY COMPANY INTEREST
                          SECURITY AND PLEDGE AGREEMENT

THIS LIMITED LIABILITY COMPANY INTEREST SECURITY AND PLEDGE AGREEMENT (as
amended from time to time, the "Agreement") is made as of February 1, 2002 by
ORIGEN FINANCIAL, L.L.C., a Delaware limited liability company ("Pledgor"), in
favor of SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP, a Michigan limited
partnership (the "Secured Party").

                                R E C I T A L S:

      A. Pledgor currently owns 100% of the membership interests in Origen
Special Purpose, L.L.C., a Delaware limited liability company, Origen
Manufactured Home Financial, L.L.C., a Delaware limited liability company, and
Origen Insurance Agency, L.L.C., a Virginia limited liability company, Origen
Financial of South Dakota, L.L.C., a Delaware limited liability company
(collectively, the "Subsidiaries").

      B. The Secured Party has agreed to make available to Pledgor and Origen
Financial, Inc. ("Origen Inc." and together with Pledgor, the "Origen
Companies") a line of credit up to the amount of $17,500,000 (the "Loan"),
pursuant to the terms and conditions of that certain Amended and Restated
Subordinated Loan Agreement dated February 1, 2002, among Pledgor, Origen Inc.
and the Secured Party (as amended from time to time, the "Loan Agreement"), and
the Related Documents (as defined in the Loan Agreement).

      C. To secure the prompt satisfaction by Pledgor of all of its obligations
to the Secured Party under the Loan Agreement and the Related Documents, Pledgor
has agreed to execute and deliver this Agreement.

      NOW, THEREFORE, the parties agree as follows:

      1. GRANT OF SECURITY INTEREST. As collateral security for the prompt and
complete payment and performance when due (whether at the stated maturity, by
acceleration or otherwise) of all liabilities, obligations and indebtedness owed
by Pledgor to the Secured Party under the Loan Agreement and the Related
Documents (collectively, the "Obligations"), Pledgor grants to the Secured Party
a first security interest in and to Pledgor's right, title and interest as a
member (the "Membership Interests") in each of the Subsidiaries, including,
without limitation, any and all moneys or other property payable or to become
payable to Pledgor or to which Pledgor now or in the future may be entitled, in
its capacity as a member in the Subsidiaries, including, without limitation, by
way of distribution, return of capital or otherwise in respect of the Membership
Interests, and, to the extent not otherwise included, all "proceeds" of the
Membership Interests as such term is defined in the Uniform Commercial Code (the
"Code") from time to time in effect in the State of Michigan (collectively, the
"Collateral").

      2. DISTRIBUTIONS. So long as no default has occurred and is continuing
under the Loan Agreement or the Related Documents (an "Event of Default"),
Pledgor shall be entitled to receive for its own use all distributions with
respect to the Membership Interests. If an Event of
<PAGE>
Default has occurred and is continuing, Pledgor shall not be entitled to receive
or retain other distributions paid in respect of the Membership Interests,
whether in redemption of, or in exchange for the Membership Interests, or
whether in connection with a reduction of capital, capital surplus or paid-in
surplus or the Membership Interests or otherwise, other than for the payment of
personal taxes of the members of the Subsidiaries associated with their
investment in Subsidiaries, and any and all such dividends or distributions
shall be forthwith delivered to the Secured Party to hold as Collateral and
shall, if received by Pledgor, be received in trust for delivery to the Secured
Party, be segregated from the other property or accounts of Pledgor, and be
forthwith delivered to the Secured Party as Collateral in the same form as so
received (with any necessary endorsements), with such Proceeds to be applied by
the Secured Party to reduce the Obligations.

      3. REGISTRATION OF PLEDGE. Concurrently with the execution of this
Agreement, Pledgor has sent to each of the Subsidiaries written instructions in
the form of Exhibit A, and has obtained from each of the Subsidiaries an
executed acknowledgment and consent in the form of Exhibit A.

      4. VOTING RIGHTS. So long as no Event of Default has occurred and is
continuing, Pledgor may exercise all voting and membership rights with respect
to the Membership Interests; provided, however, that no vote will be cast or
membership right exercised or other action taken which would be inconsistent
with or result in a breach of any provision of the Loan Agreement, the Related
Documents, or this Agreement.

      5. EVENT OF DEFAULT. If an Event of Default has occurred and is
continuing, the Secured Party may direct the Subsidiaries to register the
Membership Interests in the name of the Secured Party or its nominee, and the
Secured Party or its nominee may thereafter receive all distributions with
respect to, and exercise all voting, membership and other rights pertaining to,
the Membership Interests as if it were the absolute owner of the Membership
Interests.

      6. REPRESENTATIONS AND WARRANTIES OF PLEDGOR. Pledgor represents and
warrants to the Secured Party that (a) Pledgor is the record and beneficial
owner of, and has good and legal title to, the Membership Interests, free of any
and all liens or options in favor of, or claims of, any other person, except the
lien created by this Agreement, and (b) Pledgor has the legal right to execute
and deliver, to perform its obligations under, and to grant the security
interest in the Collateral pursuant to, this Agreement.

      7. ASSIGNMENT; PLEDGE; AMENDMENT. Without the prior written consent of the
Secured Party, Pledgor will not (i) sell, assign, transfer, exchange or
otherwise dispose of, or grant any option with respect to, the Collateral; (ii)
create or permit to exist any lien or option in favor of, or any claim of, any
person with respect to any of the Collateral, except, in either case, for the
lien created by this Agreement; or (iii) amend or modify the Origen Special
Purpose, L.L.C. Operating Agreement dated June 15, 2001, the Origen Manufactured
Home Financial, L.L.C. Operating Agreement dated June 15, 2001, the Origen
Insurance Agency, L.L.C. Operating Agreement dated June 15, 2001 or the Origen
Financial of South Dakota L.L.C. Operating Agreement dated December 11, 2001 (as
amended from time to time, collectively, the "Operating Agreements"), or enter
into any agreement or arrangement with any Subsidiary or its respective members
which amends or modifies the rights and obligations of such Subsidiary and its
respective members as set

                                     - 2 -
<PAGE>
forth in such Subsidiary's Operating Agreement. Pledgor will defend the right,
title and interest of the Secured Party in and to the Collateral against the
claims and demands of all other persons.

      8. FURTHER ASSURANCES. At any time and from time to time, upon the written
request of the Secured Party, Pledgor will promptly execute and deliver such
further instruments and documents and take such further actions as the Secured
Party may reasonably request for the purposes of obtaining or preserving the
security interest created by this Agreement, including, without limitation, the
filing of any financing or continuation statements under the Code. Pledgor
authorizes the Secured Party to file any such financing or continuation
statement without the signature of Pledgor to the extent permitted by applicable
law.

      9. REMEDIES. If an Event of Default has occurred and is continuing, the
Secured Party may exercise, in addition to all rights and remedies granted in
the Loan Agreement, the Related Documents, and this Agreement, all rights and
remedies of a secured party under the Code. The rights and remedies of the
Secured Party are cumulative, may be exercised singly or concurrently, and are
not exclusive of any rights or remedies provided by law.

      10. ATTORNEY-IN-FACT. Pledgor irrevocably constitutes and appoints the
Secured Party, or its representative, with full power of substitution, as its
true and lawful attorney-in-fact with full irrevocable power and authority in
the place and stead of Pledgor, and in the name of Pledgor or in the Secured
Party's name, after an Event of Default has occurred and for so long as it is
continuing, for the purpose of carrying out the terms of this Agreement.
Anything to the contrary contained herein notwithstanding, the Secured Party may
not exercise the rights granted to them in this Section 10 unless the Pledgor
has been provided with prior written notice of such exercise. The powers
conferred on the Secured Party are solely to protect its interests in the
Collateral and will not impose any duty upon the Secured Party to exercise any
such powers. The Secured Party will be accountable only for amounts that it
actually receives as a result of the exercise of such powers, and neither the
Secured Party, nor its General Partner, or any of their officers, directors,
employees or agents will be responsible to Pledgor or to the Subsidiaries for
any act or failure to act.

      11. LIMITATION ON DUTIES REGARDING COLLATERAL. The Secured Party's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under the Code or otherwise, will be to deal with
it in the same manner as the Secured Party deals with similar securities and
property for its own account. Neither the Secured Party, its General Partner,
nor any of their directors, officers, employees or agents will be liable for
failure to demand, collect or realize upon any of the Collateral or for any
delay in doing so or, except as provided by applicable law, will be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
Pledgor or otherwise.

      12. NO WAIVER. The Secured Party will not by any act, delay, omission or
otherwise be deemed to have waived any right or remedy under this Agreement or
to have acquiesced in any Event of Default or in any breach of any of the terms
and conditions of this Agreement except by a written instrument executed by the
Secured Party. No single or partial exercise of any right, power or privilege
under this Agreement will preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. A waiver by the Secured Party
of any right or remedy under this Agreement on any one occasion will not be
construed as a bar to any right or remedy which the

                                     - 3 -
<PAGE>
Secured Party would otherwise have on any future occasion.

      13. AMENDMENTS. The terms and provisions of this Agreement may not be
waived or modified except by a written instrument executed by Pledgor and the
Secured Party.

      14. BENEFIT AND BINDING EFFECT. This Agreement will be binding upon the
successors and permitted assigns of Pledgor and will inure to the benefit of the
Secured Party and its successors and assigns.

      15. COUNTERPARTS; REPRODUCTIONS. This Agreement may be executed in
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one instrument. Facsimile copies of signatures to this
Agreement shall be deemed to be originals, and the parties may rely upon such
facsimile copies to the same extent as the originals..

      16. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Michigan.

                          AMENDED AND RESTATED GUARANTY

      THIS AMENDED AND RESTATED GUARANTY (the "Amended Guaranty") is made
February 1, 2002 by Bingham Financial Services Corporation, a Michigan
corporation ("Bingham"), in favor of Sun Communities Operating Limited
Partnership, a Michigan limited partnership ("SCOLP").

                                    RECITALS:

      A. Guarantor has executed and delivered to Lender a Guaranty dated
December 18, 2001, as affirmed by the Affirmation of Guaranty dated January 1,
2002 (collectively, the "Original Guaranty"), pursuant to which Guarantor
guaranteed the payment and performance when due of certain obligations owing
from Origen Financial, Inc. ("Origen Inc.") to SCOLP, including without
limitation under the line of credit loan (the "Line of Credit") evidenced by the
Subordinated Loan Agreement dated December 18, 2001 between Origen Inc. and
Lender, as amended by the First Amendment to Subordinated Loan Agreement dated
January 1, 2002 (collectively, the "Original Loan Agreement") and the Promissory
Note in the original principal amount of $12,500,000 dated December 18, 2001
executed by Origen Inc. in favor of Lender, as amended by the First Amended
Promissory Note dated January 1, 2002 in the original principal amount of
$17,500,000 (collectively, the "Prior Note").

      B. The Line of Credit is secured by the collateral described in the
Amended and Restated Security Agreement dated February 1, 2002 between Origen
Inc. and SCOLP, the Amended and Restated Limited Liability Company Interest
Security and Pledge Agreement dated February 1, 2002 between Origen Inc. and
SCOLP, the Amended and Restated Stock Pledge Agreement dated February 1, 2002
between Origen Inc. and SCOLP, and various Uniform Commercial Code financing
statements filed to perfect the security interests granted under the foregoing
agreements (the "Origen Inc. Security Documents").

      C. Origen Inc., Origen Financial, L.L.C. ("Origen LLC" and together with
Origen Inc., the "Borrowers") and Lender have entered into an Amended and
Restated Subordinated Loan Agreement dated February 1, 2002 (the "Amended and
Restated Loan Agreement") and the Borrowers have executed a Second Amended and
Restated Promissory Note dated February 1, 2002 (the "Second Amended Note"),
pursuant to which Lender has agreed to make advances under the Line of Credit,
as amended, to each of the Borrowers.

      D. As further security for the Line of Credit, as amended, Origen LLC has
granted SCOLP a security interest in the collateral described in the Security
Agreement dated February 1, 2002 between Origen LLC and SCOLP and the Limited
Liability Company Interest Security and Pledge Agreement dated February 1, 2002
between Origen LLC and SCOLP (collectively, the "Origen LLC Security Documents"
and together with the Origen Inc. Security Documents, the "Origen Security
Documents").

      E. The Borrowers may from time to time request loans, advances or other
financial accommodations from SCOLP and SCOLP may, in its discretion, honor such
requests in whole or part and thereby either of the Borrowers may from time to
time be indebted to SCOLP, including without limitation, under (i) the Amended
and Restated Loan Agreement; (ii) the
<PAGE>
Second Amended Note; and (iii) the Origen Security Documents (collectively, the
"Origen Loan Documents").

      F. SCOLP is unwilling to make loans, advances or extend other financial
accommodations to or otherwise do business with the Borrowers unless Bingham
continues to unconditionally guarantee payment of all present and future
indebtedness and obligations of each of the Borrowers to SCOLP and as a
condition of amending the Line of Credit, Lender has required that Guarantor
execute and deliver this Amended Guaranty.

      G. Bingham is the sole shareholder of Origen Inc. and a member of Origen
LLC and will directly benefit from SCOLP's making of loans, advances or
extending other financial accommodations to or otherwise doing business with the
Borrowers.

      H. Bingham desires to amend and restate the original Guaranty in its
entirety in accordance with the terms and conditions set forth in this Amended
Guaranty.

      NOW, THEREFORE, in order to induce SCOLP to make loans, advances or extend
other financial accommodations to and otherwise do business with the Borrowers
and for other good and valuable consideration, the receipt and sufficiency
whereof are hereby acknowledged, Bingham hereby covenants and agrees with SCOLP
as follows:

      1. GUARANTY. Bingham hereby irrevocably and unconditionally guarantees to
SCOLP and its successors and assigns: (a) the full and prompt payment and
performance when due of the Indebtedness, as hereinafter defined; and (b) the
payment, compliance with and performance of all other obligations, covenants,
representations and warranties of every kind, nature and description in
accordance with all instruments and documents executed by either Borrower in
favor of SCOLP, whether now owing or existing or heretofore or hereafter created
or arising, regardless of whether such obligations, covenants, representations
or warranties are held to be unenforceable, void or of no effect against either
Borrower and including without limitation, those under any loan agreement and/or
promissory note executed and delivered by either Borrower to SCOLP, and any
extensions, modifications or renewals thereof. The term "Indebtedness" shall
mean all principal, interest, attorneys' fees, commitment fees, liabilities for
costs and expenses and all other indebtedness, obligations and liabilities under
and in accordance with the terms of all instruments and documents executed by
either Borrower in favor of SCOLP, whether direct or indirect, absolute or
contingent and whether now owing or existing or heretofore or hereafter created
or arising, and regardless of whether such indebtedness, obligations or
liabilities are held to be unenforceable, void or of no effect against either
Borrower, and all costs, expenses and fees, including reasonable attorneys'
fees, arising in connection with the collection or enforcement of any or all
amounts, indebtedness, obligations and liabilities of either Borrower to SCOLP,
as described above, regardless of whether either Borrower is held to be liable
for such amounts. Bingham acknowledges and agrees that any indebtedness of
either Borrower to SCOLP as evidenced by any promissory note may be extended or
renewed upon maturity at the sole discretion of SCOLP and that the Indebtedness
as defined herein, the payment of which is hereby guaranteed, shall include,
without limitation, all indebtedness and other obligations as extended or
renewed and as may be evidenced by any renewal promissory note.

                                     - 2 -
<PAGE>
      2. GUARANTY UNCONDITIONAL. This is an irrevocable, unconditional and
absolute guaranty of payment, and not of collection, and the undersigned agrees
that its liability on this Amended Guaranty shall be immediate and SCOLP may
have immediate recourse against Bingham for full and immediate payment of the
Indebtedness at any time after the Indebtedness or any part thereof, has not
been paid when due (whether by acceleration or otherwise) or Origen has
defaulted or otherwise failed to perform when due any of its obligations,
covenants, representations or warranties to SCOLP.

      3. LIABILITY NOT CONTINGENT. The liability of Bingham on this Amended
Guaranty shall not be contingent upon the exercise or enforcement by SCOLP of
whatever remedies it may have against either Borrower or others, or the
enforcement of any lien or realization upon any security or collateral SCOLP may
at any time possess. Any one or more successive and/or concurrent actions may be
brought hereon against Bingham either in the same action, if any, brought
against either Borrower or in separate actions, as often as SCOLP, in its sole
discretion, may deem advisable. No election to proceed in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of SCOLP's right to proceed in any other form of action or proceeding or
against other parties unless SCOLP has expressly waived such right in writing.
Specifically, but without limiting the generality of the foregoing, no action or
proceeding by SCOLP against either Borrower under any document or instrument
evidencing or securing the Indebtedness shall serve to diminish the liability of
Bingham, except to the extent SCOLP realizes payment by such action or
proceeding, notwithstanding the effect of any such action or proceeding upon
Bingham's right of subrogation against either Borrower. Receipt by SCOLP of
payment or payments with knowledge of the breach of any provision with respect
to any of the Indebtedness shall not, as to Bingham, be deemed a waiver of such
breach. All rights, powers and remedies of SCOLP hereunder and under any other
agreement now or at any time hereafter in force between SCOLP and Bingham shall
be cumulative and not alternative and shall be in addition to all rights, powers
and remedies given to SCOLP by law.

      4. LIABILITY ABSOLUTE. Bingham agrees that its liability hereunder is
absolute and unconditional and that SCOLP shall not be obligated (although it
may do so at its sole option) before being entitled to direct recourse against
Bingham to take any steps, whatsoever to preserve, protect, accept, perfect
SCOLP's interest in, foreclose upon or realize on collateral security, if any,
for the payment of the Indebtedness or any other guaranty of the Indebtedness or
in any other respect exercise any diligence whatever in collecting or attempting
to collect the Indebtedness by any means.

      5. NO IMPAIRMENT OF LIABILITY. The liability of Bingham shall in no way be
affected or impaired by: (a) any amendment, alteration, extension, renewal,
waiver, indulgence or other modification of the Indebtedness; (b) any settlement
or compromise in connection with the Indebtedness; (c) any subordination of
payments under the Indebtedness to any other debt or claim; (d) any
substitution, exchange, release or other disposition of all or any part of any
collateral for the Indebtedness; (e) any failure, delay, neglect, act or
omission by SCOLP to act in connection with the Indebtedness; (f) any advances
for the purpose of performing any covenant or agreement of either Borrower, or
curing any breach; (g) the filing by or against either Borrower of bankruptcy,
insolvency, reorganization or other debtor's relief afforded either

                                     - 3 -
<PAGE>
Borrower pursuant to the present or future provisions of the Bankruptcy Code or
any other state or federal statute or by the decision of any court; or (h) any
other matter whether similar or dissimilar to the foregoing. The obligations of
Bingham are unconditional, notwithstanding any defect in the genuineness,
validity, regularity or enforceability of the Indebtedness or any other
circumstances whether or not referred to herein, which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor.

      6. WAIVERS. Bingham hereby waives each and every defense which, under
principles of guaranty or suretyship law or otherwise, would otherwise operate
to impair or diminish the liability of Bingham hereunder, including, without
limitation: (a) notice of acceptance of this Amended Guaranty and of creations
of Indebtedness of either Borrower to SCOLP; (b) any subrogation to the rights
of SCOLP against either Borrower until the Indebtedness has been paid in full;
(c) presentment and demand for payment of any Indebtedness of either Borrower;
(d) protest, notice of protest, and notice of dishonor or default to Bingham or
to any other party with respect to any of the Indebtedness; (e) all other
notices to which Bingham might otherwise be entitled; (f) any demand for payment
under this Amended Guaranty; (g) any defense arising by reason of any disability
or other defense of either Borrower by reason of the cessation from any cause
whatsoever of the liability of either Borrower; (h) any rights to extension,
composition or otherwise under the Bankruptcy Code or any amendments thereof, or
under any state or other federal statute; (i) any right or claim or claim of
right to cause a marshalling of either Borrower's assets; and (j) any
participation in any of the Indebtedness by a third party. No notice to or
demand on Bingham shall be deemed to be a waiver of the obligation of Bingham or
of the right of SCOLP to take further action without notice or demand as
provided herein; nor in any event shall any modification or waiver of the
provisions of this Amended Guaranty be effective unless in writing nor shall any
such waiver be applicable except in the specific instance for which given.

      7. WARRANTIES AND REPRESENTATIONS. Bingham represents, warrants and
covenants to SCOLP that, as of the date of this Amended Guaranty: Bingham is
meeting its current liabilities as they mature; any financial statements of
Bingham furnished SCOLP are true and correct and include in the footnotes
thereto all contingent liabilities of Bingham; since the date of said financial
statements there has been no material adverse change in the financial condition
of Bingham; there are not now pending any material court or administrative
proceedings or undischarged judgments against Bingham and no federal or state
tax liens have been filed or threatened against Bingham, nor is Bingham in
default or claimed default under any agreement for borrowed money.

      8. NOTICES. Bingham agrees to immediately give SCOLP written notice of any
material adverse change in its financial condition, including but not limited to
litigation commenced, tax liens filed, default claimed under its indebtedness
for borrowed money or bankruptcy proceedings commenced by or against Bingham.
Bingham agrees to deliver, timely to SCOLP, annual financial statements for the
preceding fiscal year; and at such reasonable times as SCOLP requests to furnish
its current financial statements to SCOLP and permit SCOLP or its
representatives to inspect at Bingham's offices, its financial records and
properties and make extracts therefrom in order to evaluate the financial
condition of Bingham.

                                     - 4 -
<PAGE>
      9. MISCELLANEOUS. This Amended Guaranty shall inure to the benefit of
SCOLP and its successors and assigns, including each and every holder or owner
of any of the indebtedness guaranteed hereby. In the event that any person other
than SCOLP shall become a holder or owner of any of the Indebtedness, each
reference to SCOLP hereunder shall be construed as if it referred to each such
holder or owner. This Amended Guaranty shall be binding upon Bingham and its
successors and assigns. Bingham agrees that recourse may be had against its
earnings and separate property for all of Bingham's obligations under this
Amended Guaranty. This Amended Guaranty and all rights and obligations
hereunder, including matters of construction, validity and performance, shall be
governed by the laws of the State of Michigan.

      10. JURY WAIVER. BINGHAM ACKNOWLEDGES THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. BINGHAM, AFTER CONSULTING (OR
HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, KNOWINGLY AND
VOLUNTARILY, AND FOR ITS BENEFIT WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT
OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED
TO, THIS AMENDED GUARANTY OR THE INDEBTEDNESS.

      11. COLLATERAL. This Amended Guaranty is secured by the collateral
described in (i) the Amended and Restated Security Agreement dated December 13,
1999, as amended, between SCOLP and Bingham; (ii) the Membership Pledge
Agreement dated December 13, 1999 between SCOLP and Bingham (with respect to
membership interests in Bloomfield Acceptance Company, L.L.C. and Bloomfield
Servicing Company, L.L.C.); (iii) the Stock Pledge Agreement dated December 13,
1999 between SCOLP and Bingham; (iv) the Stock Pledge Agreement dated October
20, 2000 between SCOLP and Bingham; and (v) various Uniform Commercial Code
