 GENSYM CORPORATION 
  
 Description of Compensation Arrangements with Non-Employee Directors 
  
 Directors of the Company who are also Company employees receive no additional or special compensation for serving as
directors. 
  
 Following is a description of the compensation
arrangements for the Company’s non-employee directors. 
  
 The Company pays, and after March 31, 2006 will continue to pay, its non-employee directors $12,000 annually, plus $1,000 for physical attendance at each meeting of the board of directors or $500 for
participation in a board meeting telephonically. Non-employee directors also receive a $2,500 quarterly retainer for each committee on which the director serves. Non-employee directors are also eligible to receive stock options. 
  
 Prior to March 31, 2006, each of the Company’s
non-employee directors is required to receive 10%, and may elect to receive up to 100%, of his board compensation in shares of the Company’s common stock in lieu of cash. Each director must make his election in increments of 10% and may only
change his election effective as of two specified times each year. Effective March 31, 2006, all non-employee director fees will be paid solely in cash, and Company common stock will no longer be issued in lieu of cash for any portion of
director compensation (retainers or meeting fees). 
  
 Additionally, since January 1, 2005, upon initial election as a director, each non-employee director has been entitled to receive a nonstatuory option to purchase 10,000 shares of the Company’s common stock and on the first day of
each calendar quarter each non-employee director has been entitled to receive an option to purchase 2,500 shares. All options granted to directors are granted at an exercise price equal to the fair market value of the Company’s common stock on
the date of the grant, are immediately exercisable and are exercisable for up to 10 years from the date of grant. Effective March 31, 2006, options will no longer be granted to any non-employee director (1) who owns 5% or more of the
Company’s outstanding common stock or (2) if and to the extent the grant would cause the total number of shares subject to options ever granted by the Company to the non-employee director to exceed 100,000 (subject to adjustment for
stock-splits, dividends and similar events).From of Mortgage Loan Purchase Agreement

 ARTICLE II 
 SALE OF MORTGAGE LOANS AND RELATED PROVISIONS 
 Section 2.01 Sale of Initial Mortgage Loans
and MI Policies. 
 (a) The Seller hereby sells, and the Depositor hereby purchases on the Closing Date the Initial Mortgage Loans
identified (and the related MI Policies) on the Mortgage Loan Schedule annexed hereto as Exhibit 1, the proceeds thereof and all rights under the Related Documents (including the related Mortgage Files). The Initial Mortgage Loans consist of a group

transfer in immediately available funds on the Closing Date by or on behalf of the Depositor, or as otherwise agreed by the Depositor; and

 (b) [Reserved] 
 (c) In connection with such conveyances by the Seller, the Seller shall on behalf of and at
the direction of the Depositor deliver to, and deposit with the Custodian on behalf of the Trustee, on or before the Closing Date in the case of an Initial Mortgage Loan and two Business Days prior to the related Subsequent Transfer Date in the case
of a Subsequent Mortgage Loan, the following documents or instruments with respect to each Mortgage Loan (the “Mortgage File”): 
 (i) the original Mortgage Note endorsed to “JPMorgan Chase Bank, National Association, as Trustee of the NovaStar Mortgage Funding Trust, Series 20[    ]-[    ], relating
to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 20[    ]-[    ]”; 
  

 2 

 (ii) the original Mortgage with evidence of recording thereon, or, if the original
Mortgage has not yet been returned from the public recording office, a copy of the original Mortgage certified by the Seller or the public recording office in which such original Mortgage has been recorded and if the Mortgage Loan is registered on
the MERS System, such Mortgage shall include thereon a statement that it is a MOM Loan and shall include the MIN for such Mortgage Loan; 
 (iii) unless the Mortgage Loan is registered on the MERS System, an original assignment (which may be included in one or more blanket assignments if permitted by applicable law) of the Mortgage endorsed to
“JPMorgan Chase Bank, National Association, as Trustee of the NovaStar Mortgage Funding Trust, Series 20[ ]-[ ], relating to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 20[ ]-[ ],” and otherwise in recordable form;

 (iv) originals of any intervening assignments of the Mortgage showing an unbroken chain of title from the originator
thereof to the Person assigning it to the Trustee (or to MERS, if the Mortgage Loan is registered on the MERS System, and noting the presence of a MIN, if the Mortgage Loan is registered on the MERS System), with evidence of recording thereon, or,
if the original of any such intervening assignment has not yet been returned from the public recording office, a copy of such original intervening assignment certified by the Seller or the public recording office in which such original intervening
assignment has been recorded; 
 (v) the original policy of title insurance (or a commitment for title insurance, if the
policy is being held by the title insurance company pending recordation of the Mortgage); 
 (vi) true and correct copy of
each assumption, modification, consolidation or substitution agreement, if any, relating to the Mortgage Loan; and 
 (vii) an
executed copy of the notice of assignment and acknowledgement of assignment with respect to the Mortgage Loans covered by the MI Policies. 
 If a material defect in any Mortgage File is discovered which may materially and adversely affect the value of the related Mortgage Loan, or the interests of the Trustee (as pledgee of the Mortgage Loans), or the Certificateholders in such
Mortgage Loan, including if any document required to be delivered to the Custodian has not been delivered (provided that a Mortgage File will not be deemed to contain a defect for an unrecorded assignment under clause (i) above for 180 days
following submission of the assignment if the Seller has submitted such assignment for recording pursuant to the terms of the following paragraph), the Seller shall cure such defect, repurchase the related Mortgage Loan at the Repurchase Price or
substitute an Eligible Substitute Mortgage Loan for the related Mortgage Loan upon the same terms and conditions set forth in Section 3.01 hereof as to the Initial Mortgage Loans and the Subsequent Mortgage Loans and Section 2.02(c) hereof
as to the Subsequent Mortgage Loans for breaches of representations and warranties. 
  

 3 

 Promptly after the Closing Date in the case of an Initial Mortgage Loan or, in the case of a Subsequent
Mortgage Loan, promptly after the Subsequent Transfer Date (or after the date of transfer of any Eligible Substitute Mortgage Loan), the Seller at its own expense shall complete and submit for recording in the appropriate public office for real
property records each of the assignments referred to in clause (iii) above, with such assignment completed in favor of the Trustee, excluding any Mortgage Loan that is registered on the MERS System if MERS is identified on the Mortgage or on a
properly recorded assignment of Mortgage as the mortgagee of record. While such assignment to be recorded is being recorded, the Custodian shall retain a photocopy of such assignment. If any assignment is lost or returned unrecorded to the Custodian
because of any defect therein, the Seller is required to prepare a substitute assignment or cure such defect, as the case may be, and the Seller shall cause such substitute assignment to be recorded in accordance with this paragraph. 
 In instances where an original Mortgage or any original intervening assignment of Mortgage is not, in accordance with clause (ii) or
(iv) above, delivered by the Seller to the Custodian, on behalf of the Trustee, prior to or on the Closing Date in the case of an Initial Mortgage Loan or, in the case of a Subsequent Mortgage Loan, prior to or on the Subsequent Transfer Date,
the Seller will deliver or cause to be delivered the originals of such documents to the Custodian, on behalf of the Trustee, promptly upon receipt thereof. 
 In connection with the assignment of any Initial Mortgage Loan registered on the MERS System, promptly after the Closing Date, the Seller further agrees that it will cause, at the Seller’s own expense, the MERS
System to indicate that such Initial Mortgage Loan has been assigned by the Seller to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including in such computer files (a) the applicable Trustee code in
the field “Trustee” which identifies the Trustee and (b) the code “NovaStar 20[    ]-[    ]” (or its equivalent) in the field “Pool” which identifies the series of the
Certificates issued in connection with such Mortgage Loans. The Custodian will certify in its final certification that the MERS System shows the Trustee on behalf of the Certificateholders as the beneficial owner of the Mortgage Loans registered on
the MERS System. 
 Effective on the Closing Date, the Depositor hereby acknowledges its acceptance of all right, title and interest to the
Initial Mortgage Loans and other property, existing on the Closing Date and thereafter created and conveyed to it pursuant to this Section 2.01. 
 The Trustee, as assignee or transferee of the Depositor, shall be entitled to all scheduled principal payments due after the Cut-off Date, all other payments of principal due and collected after the Cut-off Date, and
all payments of interest on the Initial Mortgage Loans. No scheduled payments of principal due on or before the Cut-off Date and collected after the Cut-off Date shall belong to the Depositor pursuant to the terms of this Purchase Agreement. The
Pooling and Servicing Agreement shall provide that any late payment charges collected in connection with a Mortgage Loan shall be paid to the Servicer as provided therein. 
 (d) The parties hereto intend that the transactions set forth herein constitute a sale by the Seller to the Depositor on the Closing Date of all the
Seller’s right, title and interest in and to the Initial Mortgage Loans and other property as and to the extent described above. In the event the transactions set forth herein shall be deemed not to be a sale, the Seller hereby grants to

 the Depositor as of the Closing Date a security interest in all of the Seller’s right, title and interest in, to and
under the Initial Mortgage Loans and such other property, to secure all of the Seller’s obligations hereunder and this Purchase Agreement shall constitute a security agreement under applicable law and in such event, the parties hereto
acknowledge that the Custodian, in addition to holding the Initial Mortgage Loans on behalf of the Trustee for the benefit of the Certificateholders, holds the Initial Mortgage Loans as designee of the Depositor. The Seller agrees to take or cause
to be taken such actions and to execute such documents, including without limitation the filing of all necessary UCC-1 financing statements filed in the Commonwealth of Virginia (which shall have been submitted for filing as of the Closing Date and
each Subsequent Transfer Date, as applicable), any continuation statements with respect thereto and any amendments thereto required to reflect a change in the name or corporate structure of the Seller, as are necessary to perfect and protect the
interests of the Depositor and their respective assignees in each Initial Mortgage Loan and the proceeds thereof and the interests of the Trustee and its assignees in each Subsequent Mortgage Loan and the proceeds thereof. The Depositor agrees to
take or cause to be taken such actions and to execute such documents, including without limitation the filing of all necessary UCC-1 financing statements, and continuation statements with respect thereto and any amendments thereto as are necessary
to perfect and protect the interests of the Trustee and its assignees in each Initial Mortgage Loan.

not intended that any Mortgage Loan be included in the Trust Fund that is a “High-Cost Home Loan” as defined in the New Jersey Home Ownership Act, effective as of November 27, 2003, the Home Loan Protection Act of New Mexico,
effective as of January 1, 2004, the Massachusetts Predatory Home Loan Practices Act, effective as of November 7, 2004, or the Indiana Home Loan Practices Act effective January 1st, 2005.

the Trustee, of the Subsequent Mortgage Loans identified on each Mortgage Loan Schedule attached to the related Subsequent Transfer Instrument and the related MI Policies shall be absolute and is intended by the Trustee, the Depositor and the Seller
to constitute and to be treated as a sale of the Subsequent Mortgage Loans by the Seller to the Depositor, and a sale of the Subsequent Mortgage Loans by the Depositor to the Trustee.

and protect the interests of the Depositor and its assignees in the Subsequent Mortgage Loans. 
 In the event such transactions shall be
deemed not to be a sale, the Depositor hereby grants to the Trustee as of each Subsequent Transfer Date a security interest in all of the Depositor’s right, title and interest in, to and under the related Subsequent Mortgage Loans and such
other property, to secure all of the Depositor’s obligations hereunder, and this Purchase Agreement shall constitute a security agreement under applicable law, and in such event, the parties hereto acknowledge that the Custodian, in addition to

 In the event that the Seller elects to substitute an Eligible Substitute Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant to this

Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Servicer and remitted by the Servicer to the Seller on the next succeeding Payment Date. For the month of substitution,
distributions to the Collection Account pursuant to the Pooling and Servicing Agreement will include the Monthly Payment due on a Deleted Mortgage Loan for such month and thereafter the Seller shall be entitled to retain all amounts received in
respect of such Deleted Mortgage Loan. The Servicer shall amend or cause to be amended the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan and the substitution of the Eligible Substitute Mortgage Loan or Loans and the

Agreement in all respects, the Seller shall be deemed to have made the representations and warranties with respect to the Eligible Substitute Mortgage Loan contained herein set forth in this Section 3.01(b), to the extent set forth in the
definition of “Eligible Substitute Mortgage Loan”, as of the date of substitution, and the Seller shall be obligated to repurchase or substitute for any Eligible Substitute Mortgage Loan as to which a Repurchase Event has occurred as

any, by which (i) the Repurchase Price that would otherwise apply to such Deleted Mortgage Loan, exceeds (ii) the principal balance of the related Eligible Substitute Mortgage Loan (after application of the principal portion of the Monthly
Payments due in the month of substitution that are to be distributed to the Collection Account in the month of substitution). The Seller shall pay the amount of such shortfall to the Servicer for deposit into the Collection Account on the day of
substitution, without any reimbursement therefor. 
  

 26 

 Upon receipt by the Trustee of written notification, signed by a Servicing Officer, of the deposit of
such Repurchase Price or of such substitution of an Eligible Substitute Mortgage Loan and deposit of any applicable Substitution Adjustment Amount as provided above, the Custodian shall, on behalf of the Trustee, cause to be released to the Seller
the related Mortgage File for the Mortgage Loan being repurchased or substituted for and the Trustee shall execute and deliver such instruments of transfer or assignment prepared by the Servicer, in each case without recourse, as shall be necessary
to vest in the Seller or its designee such Mortgage Loan released pursuant hereto and thereafter such Mortgage Loan shall not be an asset of the Trustee. 
 It is understood and agreed that the obligation of the Seller to cure any breach with respect to or to repurchase or substitute for, any Mortgage Loan as to which such a breach has occurred and is continuing shall,
except to the extent provided in Section 6.01 of this Purchase Agreement, constitute the sole remedy respecting such breach available to the Depositor, the Trustee, the Certificateholders or the Custodian against the Seller. 
 It is understood and agreed that the representations and warranties set forth in this Section 3.01 shall survive delivery of the respective Mortgage
Files to the Custodian on behalf of the Trustee.

 Section 8.08 Intention of the Parties. 
 It is the intention of the parties that (i) the Depositor is purchasing on the Closing Date, and the Seller is selling on the Closing Date, the Initial Mortgage Loans, rather than the Depositor providing to the Seller a loan secured by
the Initial Mortgage Loans on the Closing Date, and (ii) the Trustee is purchasing on the Closing Date, and the Depositor is selling on the Closing Date, the Initial Mortgage Loans, rather than the Trustee providing to the Depositor a loan
secured by the Initial Mortgage Loans, (iii) the Depositor will be purchasing on each Subsequent Transfer Date, and the Seller will be selling on each Subsequent Transfer Date, the related Subsequent Mortgage Loans, rather than the Depositor
providing to the Seller a loan secured by the related Subsequent Mortgage Loans on each Subsequent Transfer Date, and (iv) the Trustee will be purchasing on each Subsequent Transfer Date, and the Depositor will be selling on each Subsequent
Transfer Date, the related Subsequent Mortgage Loans, rather than the Trustee providing to the Depositor a loan secured by the related Subsequent Mortgage Loans on each Subsequent Transfer Date. Accordingly, the parties hereto each intend to treat
these transactions as (i) a sale by the Seller, and a purchase by the Depositor, of the Initial Mortgage Loans on the Closing Date, and (ii) a sale by the Depositor, and a purchase by the Trustee, of the Initial Mortgage Loans on the
Closing Date, (iii) a sale by the Seller, and a purchase by the Depositor, of the related Subsequent Mortgage Loans on each Subsequent Transfer Date, and (iv) a sale by the Depositor, and a purchase by the Trustee, of the related
Subsequent Mortgage Loans on each Subsequent Transfer Date. 
 Section 8.09 Successors and Assigns; Assignment of Purchase
Agreement. 
 This Purchase Agreement shall bind and inure to the benefit of and be enforceable by the Seller, the Depositor, the Trustee,
the Custodian, and their respective successors and assigns. The obligations of the Seller under this Purchase Agreement cannot be assigned or delegated to a third party without the consent of the Depositor, which consent shall be at the
Depositor’s discretion. The parties hereto acknowledge that (i) the Depositor is acquiring the Initial Mortgage Loans for the purpose of selling them to the Trustee, who will hold the Initial 
  

 34 

 Mortgage Loans in trust for the benefit of the Certificateholders and (ii) the Depositor is acquiring the Subsequent
Mortgage Loans for the purpose of selling them to the Trustee, who will hold the Subsequent Mortgage Loans for the benefit of the Certificateholders. As an inducement to the Depositor and the Trustee to purchase the Mortgage Loans, the Seller
acknowledges and consents to (i) the assignment by the Depositor to the Trustee of all of the Depositor’s rights or remedies against the Seller pursuant to this Purchase Agreement and to (ii) the enforcement or exercise of any rights
against the Seller pursuant to this Purchase Agreement by the Depositor and the Trustee. Such enforcement of a right or remedy by the Trustee, shall have the same force and effect as if the right or remedy had been enforced or exercised by the
Depositor directly. 
 Section 8.10 Survival. 
 The representations and warranties made herein by the Seller and the provisions of Article V hereof shall survive the purchase of the Mortgage Loans hereunder. 
 Section 8.11 Liability of the Trustee. 
 The Trustee is entering into the Basic Documents to which it is a party solely as Trustee, hereunder and thereunder, and not in its individual capacity, and all persons having any claim against the Trustee by reason of the transactions
contemplated by this Agreement or any other Basic Document shall look only to the Trust Fund for payment or satisfaction thereof.
