         Re:      Master Repurchase Agreements Waiver

     Reference is made to those certain Master  Repurchase  Agreements listed on
Schedule I attached hereto (the  "Agreements").  Capitalized  terms used in this
letter agreement  without  definition have the meanings  ascribed to them in the
Agreements.

     Effective  as of the date  hereof and until  January  4, 2008 (the  "Waiver
Period") and subject to the limitations set forth herein, each Buyer hereby:

     A.        1.   Agrees  not  to  enforce  the   requirements   for  NovaStar
                    Financial,  Inc.  ("NFI") to  maintain  a required  Adjusted
                    Tangible Net Worth under the Agreements;

               2.   Waives  any breach  and/or  any event of default  that would
                    otherwise  arise under the Agreements  solely as a result of
                    the failure of NFI to have the  required  Adjusted  Tangible
                    Net Worth specified in the Agreements; or

               3.   Agrees that in the Monthly  Certificates  delivered  by NFI,
                    NFI may carve-out the  certification  solely relating to the
                    Adjusted  Tangible Net Worth for the previous month and each
                    Buyer hereby  waives any breach and/or event of default that
                    would  otherwise  arise under the  Agreements as a result of
                    such carve-out from the Monthly Certifications.

      B.       1.   Agrees,  during  the  Waiver  Period,  not  to  enforce  the
                    requirements  for  NovaStar   Financial,   Inc.  ("NFI")  to
                    maintain Liquidity in an amount not less than $30,000,000 as
                    specified under the

                                           Wachovia NovaStar TNW Waiver 12-07-07

                    Agreements;  provided that NFI agrees to maintain  Liquidity
                    that could be drawn  against  (taking into account  required
                    haircuts) in an amount not less than $24,000,000;

               2.   Waives  any breach  and/or  any event of default  that would
                    otherwise  arise under the Agreements  solely as a result of
                    the  failure of NFI to maintain  Liquidity  in an amount not
                    less than  $30,000,000  during the Waiver  Period;  provided
                    that NFI maintains  Liquidity in an amount not less than the
                    $24,000,000 during the Waiver Period;

               3.   Agrees that in the  Monthly  Certificates  delivered  by NFI
                    during   the   Waiver   Period,   NFI  may   carve-out   the
                    certification   solely   relating  to  the   maintenance  of
                    Liquidity  in an amount  not less than  $30,000,000  for the
                    previous  month and each  Buyer  hereby  waives  any  breach
                    and/or event of default that would otherwise arise under the
                    Agreements  as a result of such  carve-out  from the Monthly
                    Certifications;  provided that NFI maintains Liquidity in an
                    amount  not  less  than   $24,000,000  for  such  month  and
                    certifies that it has maintained  such amount in the Monthly
                    Certification.

Notwithstanding  anything  to the  contrary  herein,  all parties  bound  herein
acknowledge  and agree that the Buyers,  shall retain all rights and remedies in
order to  enforce  any Event of  Default  or other  breach  contemplated  by the
Agreements.

     Notwithstanding  the  occurrence  and  continuance  of the NFI's failure to
maintain the required  Adjusted  Tangible Net Worth or  maintenance of Liquidity
under the Agreements  described above, each Buyer is willing to waive certain of
its  rights;  provided  that  each  Buyer  reserves  the  right to  unilaterally
terminate this letter  agreement on or prior to January 4, 2008,  without notice
to any party,  based upon the  occurrence of any Event of Default or breach that
occurs under the  Agreements on or after the date hereof other than the Event of
Default  expressly  waived by the Buyers herein.  Either Buyer's exercise of the
right to terminate this letter agreement shall be effective as to both Buyers.

     Each  Buyer  hereby  expressly  reserves  all  other  rights  and  remedies
available to it under the Agreements, and all rights, remedies, obligations, and
liabilities  created or evinced  thereby with respect to future  breaches of, or
Defaults or Events of Default under,  the  Agreements.  Except as stated herein,
the  Buyers  shall not be deemed to have  waived or  modified  any of its rights
hereunder or under any other  agreement,  instrument or paper signed by NovaStar
Mortgage,  Inc.,  NovaStar  Certificates  Financing LLC,  NovaStar  Certificates
Financing Corporation,  NFI Repurchase Corporation,  NMI Repurchase Corporation,
NMI  Property  Financing,  Inc.,  HomeView  Lending,  Inc.,  NFI and NFI Holding
Corporation  (collectively,  the  "NovaStar  Parties")  unless  such  waiver  or
modification  is in  writing  and  signed by the  Buyers.  Except  as  expressly
provided herein, no failure or delay on the part of the Buyers in exercising any
right,  power or remedy  hereunder or any of the  Agreements  shall operate as a
waiver  thereof;  nor shall any single

                                           Wachovia NovaStar TNW Waiver 12-07-07

                                       2

or partial  exercise of any such right,  power or remedy  preclude  any other or
further  exercise  thereof or the exercise of any other  right,  power or remedy
hereunder.  This letter agreement shall be construed in accordance with the laws
of the  State of New York,  and the  obligations,  rights  and  remedies  of the
parties  hereunder  shall be determined in accordance with the laws of the State
of New York except to the extent  preempted by federal law. Any provision hereof
which is prohibited  or  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability without invalidating the remaining provisions hereof or thereof
or  affecting  the  validity or  enforceability  of such  provision in any other
jurisdiction.

     This letter agreement may be executed in any number of  counterparts,  each
of which (including any copy hereof delivered by facsimile) shall constitute one
and the same  original  instrument,  and either  party  hereto may execute  this
letter agreement by signing any such counterpart.
