rights of National Rural to interest, principal or other distributions that
National Rural is authorized to receive pursuant to paragraph (a)(iii) of
this Section 2.08 shall cease, and all such suspended rights shall
thereupon become vested in the Collateral Agent, which shall have the sole and
exclusive right and authority to receive and retain such interest, principal or
other distributions.  All interest, principal or other distributions
received by National Rural contrary to the provisions of this Section 2.08
shall be held in trust for the benefit of the Collateral Agent, shall be
segregated from other property or funds of National Rural and shall be forthwith
delivered to the Collateral Agent in the same form as so received (with any
necessary endorsement).  Any and all money and other property paid over to
or received by the Collateral Agent pursuant to the provisions of this paragraph
(b) shall be retained by the Collateral Agent in an account to be established by
the Collateral Agent upon receipt of such money or other property and shall be
applied in accordance with the provisions of Section 4.03 to the fullest
extent permitted by applicable law.  After all Events of Default have
ceased, the Collateral Agent shall promptly repay to National Rural (without
interest) all interest, principal or other distributions that National Rural
would otherwise be permitted to retain pursuant to the terms of paragraph
(a)(iii) of this Section 2.08 and that remain in such account.

       

      (c)  If
an Event of Default shall have occurred and be continuing, then, to the extent
such rights are suspended by the applicable Control Party Notice of Default, all
rights of National Rural to exercise the voting and consensual rights and powers
it is entitled to exercise pursuant to paragraph (a)(i) of this
Section 2.08, and the obligations of the Collateral Agent under
paragraph (a)(ii) of this Section 2.08, shall cease, and all such
rights shall thereupon become vested in the Collateral Agent, which shall have
the sole and exclusive right and authority to exercise such voting and
consensual rights and powers; provided that the
Collateral Agent shall have the right from time to time during the existence of
such Event of Default to permit National Rural to exercise such rights and
powers.

       

      SECTION
2.09.  Protection
of Title; Payment of Taxes; Liens, etc.  National Rural will:

       

      (i) duly
and promptly pay and discharge, or cause to be paid and discharged, before they
become delinquent, all taxes, assessments, governmental and other charges
lawfully levied, assessed or imposed upon or against any of the Pledged
Collateral, including the income or profits therefrom and the interests of the
Collateral Agent in such Pledged Collateral;

       

      (ii) duly
observe and conform to all valid requirements of any governmental authority
imposed upon National Rural relative to any of the Pledged Collateral, and all
covenants, terms and conditions under or upon which any part thereof is
held;

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      11

       

      (iii)
cause to be paid and discharged all lawful claims (including, without
limitation, income taxes) which, if unpaid, might become a lien or charge upon
Pledged Collateral; and

       

      (iv) do
all things and take all actions necessary to keep the Lien of this Pledge
Agreement a first and prior lien upon the Pledged Collateral and protect its
title to the Pledged Collateral against loss by reason of any foreclosure or
other proceeding to enforce any lien prior to or pari passu with the Lien
of this Pledge Agreement.

       

      Nothing
contained in this Section shall require the payment of any such tax,
assessment, claim, lien or charge or the compliance with any such requirement so
long as the validity, application or amount thereof shall be contested in good
faith; provided, however, that
National Rural shall have set aside on its books such reserves (segregated to
the extent required by generally accepted accounting principles) as shall be
deemed adequate with respect thereto as determined by the Board of Directors of
National Rural (or a committee thereof).

       

      SECTION
2.10.  Maintenance of Pledged
Collateral.  National Rural
shall cause the Allowable Amount of Pledged Collateral held by the Collateral
Agent at all times to be not less than 100% of the aggregate principal amount of
the Notes outstanding.

       

      SECTION
2.11.  Representations, Warranties
and Covenants.  National Rural
represents, warrants and covenants to the Collateral Agent, for the benefit of
the Control Party, that from the time that they are pledged hereunder, and for
so long as they are required to remain pledged:

       

      (a)
except for the Lien hereof and any Lien consented to in writing by Farmer Mac or
the Control Party, National Rural (i) is and will continue to be the direct
owner, beneficially and of record, of the Pledged Securities from time to time
pledged hereunder, (ii) holds and will continue to hold the same free and
clear of all Liens, other than Liens created by this Pledge Agreement,
(iii) will make no assignment, pledge, hypothecation or transfer of, or
create or permit to exist any security interest in or other Lien on, the Pledged
Collateral, other than Liens created by this Pledge Agreement and (iv) will
defend its title or interest thereto or therein against any and all Liens (other
than the Lien created by this Pledge Agreement), however arising, of all Persons
whomsoever;

       

      (b)
except for restrictions and limitations imposed by the Note Purchase Agreement
or securities laws generally, the Pledged Securities are and will continue to be
freely transferable and assignable, and none of the Pledged Securities are or
will be subject to any restriction of any nature that might prohibit, impair,
delay or otherwise affect the pledge of such Pledged Securities hereunder, the
sale or disposition thereof pursuant hereto or the exercise by the Collateral
Agent of rights and remedies hereunder;

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      12

       

      (c)
National Rural has the power and authority to pledge the Pledged Collateral
pledged by it hereunder in the manner hereby done or contemplated;

       

      (d) no
consent or approval of any governmental authority, any securities exchange or
any other Person was or is necessary to the validity of the pledge effected
hereby (other than such as have been obtained and are in full force and effect);
and

       

      (e) by
virtue of the execution and delivery by National Rural of this Pledge Agreement,
when any Pledged Securities are delivered to the Collateral Agent in accordance
with this Pledge Agreement, the Collateral Agent will obtain a legal and valid
Lien upon and security interest in such Pledged Securities as security for the
payment and performance of the Obligations.

       

      SECTION
2.12.  Further
Assurances.  National Rural
will execute and deliver, or cause to be executed and delivered, all such
additional instruments and do, or cause to be done, all such additional acts as
(a) may be necessary or proper, consistent with the Granting Clause hereof,
to carry out the purposes of this Pledge Agreement and to make subject to the
Lien hereof any property intended so to be subject or (b) may be necessary
or proper to transfer to any successor the estate, powers, instruments and funds
held hereunder and to confirm the Lien of this Pledge Agreement.  National
Rural will also cause to be filed, registered or recorded any instruments of
conveyance, transfer, assignment or further assurance in all offices in which
such filing, registering or recording is necessary to the validity thereof or to
give notice thereof.

      Remedies

       

      SECTION
4.01.  Events of
Default.  “Event of Default”,
wherever used herein, means any “Event of Default” as defined in
Sections 7.01(a) of the Note Purchase Agreement, provided that, for
the purposes of this Pledge Agreement:

       

      (a) the
Collateral Agent shall not be required to recognize that an Event of Default
exists before such time as the Collateral Agent receives a Control Party Notice
or National Rural Notice stating that an Event of Default exists and specifying
the particulars of such default in reasonable detail; and

       

      (b) the
Collateral Agent shall not be required to recognize that an Event of Default has
ceased until (i) such time as the Collateral Agent receives a Control Party
Notice stipulating that such event has ceased to exist; or (ii) 30 days after
receipt by the Collateral Agent of a National Rural Notice stipulating that such
event has ceased to exist, provided that the
Collateral Agent does not receive a Control Party Notice within such timeframe
disputing the cessation of such Event of Default, and further provided that
no additional Control Party Notice of Default shall have been received in
respect of any other subsisting Event(s) of Default.  Upon receipt of any
National Rural Notice under subparagraph (ii) of this Subsection, the Collateral
Agent shall provide a copy of such National Rural Notice to the Control
Party.

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      13

       

      SECTION
4.02.  Remedies
upon Default.  If an Event of
Default shall have occurred and be continuing, the Control Party may issue a
notice (a “Control
Party Notice of Default”), which may be combined with the notice provided
under Section 4.01(b), suspending the rights of National Rural under
Section 2.08 in part without suspending all such rights (as specified by
the Control Party in its sole and absolute discretion) without waiving or
otherwise affecting the Control Party’s rights to give additional Control Party
Notices of Default from time to time suspending other rights under
Section 2.08 so long as an Event of
Default has occurred and is continuing.  Subject to paragraph (b) of this
Section 4.02, upon cessation of an Event of Default, all rights of National
Rural suspended under the applicable Control Party Notice of Default shall
revest in National Rural.

       

      (a)  Upon
the occurrence of an Event of Default, the Collateral Agent shall, for the
benefit and at the direction of the Control Party, have the right to exercise
any and all rights afforded to a secured party under the Uniform Commercial Code
or other applicable law.  Without limiting the generality of the foregoing,
National Rural agrees that the Collateral Agent shall have the right, but only
if so instructed by a the Control Party Order and subject to the requirements of
applicable law and the Collateral Agent’s right (in its sole and absolute
discretion) to receive indemnification or other reasonable assurances that its
costs and expenses in connection therewith will be paid, to sell or otherwise
dispose of all or any part of the Pledged Collateral at a public or private sale
or at any broker’s board or on any securities exchange, for cash, upon credit or
for future delivery as the Collateral Agent shall deem appropriate.  The
Collateral Agent shall be authorized at any such sale of securities (if it deems
it advisable to do so) to restrict the prospective bidders or purchasers to
Persons who will represent and agree that they are purchasing the Pledged
Collateral for their own account for investment and not with a view to the
distribution or sale thereof, and upon consummation of any such sale the
Collateral Agent shall have the right to assign, transfer and deliver to the
purchaser or purchasers thereof the Pledged Collateral so sold.  Each such
purchaser at any sale of Pledged Collateral shall hold the property sold
absolutely, free from any claim or right on the part of National Rural, and
National Rural hereby waives (to the extent permitted by law) all rights of
redemption, stay and appraisal which National Rural now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted.

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      14

       

      (b)  The
Collateral Agent shall give National Rural 10 days’ written notice (which
National Rural agrees is reasonable notice within the meaning of
Section 9-611 of the Uniform Commercial Code or its equivalent in other
jurisdictions) of the Collateral Agent’s intention to make any sale of Pledged
Collateral.  Such notice, in the case of a public sale, shall state the
time and place for such sale and, in the case of a sale at a broker’s board or
on a securities exchange, shall state the board or exchange at which such sale
is to be made and the day on which the Collateral, or portion thereof, will
first be offered for sale at such board or exchange.  Any such public sale
shall be held at such time or times within ordinary business hours and at such
place or places as the Collateral Agent may fix and state in the notice (if any)
of such sale.  At any such sale, the Pledged Collateral, or portion
thereof, to be sold may be sold in one lot as an entirety or in separate
parcels, as the Collateral Agent may (in its sole and absolute discretion)
determine.  The Collateral Agent shall not be obligated to make any sale of
any Pledged Collateral if it shall determine not to do so, regardless of the
fact that notice of sale of such Pledged Collateral shall have been given. 
The Collateral Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned.  In case
any sale of all or any part of the Pledged Collateral is made on credit or for
future delivery, the Pledged Collateral so sold may be retained by the
Collateral Agent until the sale price is paid by the purchaser or purchasers
thereof, but the Collateral Agent shall not incur any liability in case any such
purchaser or purchasers shall fail to take up and pay for the Pledged Collateral
so sold and, in case of any such failure, such Pledged Collateral may be sold
again upon like notice.  At any public (or, to the extent permitted by law,
private) sale made pursuant to this Pledge Agreement, the Control Party may bid
for or purchase, free (to the extent permitted by law) from any right of
redemption, stay, valuation or appraisal on the part of National Rural (all said
rights being also hereby waived and released to the extent permitted by law),
the Pledged Collateral or any part thereof offered for sale and may make payment
on account thereof by using any claim then due and payable to the Control Party
from National Rural as a credit against the purchase price, and the Control
Party may, upon compliance with the terms of sale, hold, retain and dispose of
such property without further accountability to Pledged Collateral
therefor.  For purposes hereof, a written agreement to purchase the Pledged
Collateral or any portion thereof shall be treated as a sale thereof; the
Collateral Agent shall be free to carry out such sale pursuant to such agreement
and National Rural shall not be entitled to the return of the Pledged Collateral
or any portion thereof subject thereto, notwithstanding the fact that after the
Collateral Agent shall have entered into such an agreement all Events of Default
shall have been remedied and the Obligations paid in full.  As an
alternative to exercising the power of sale herein conferred upon it, the
Collateral Agent may proceed by a suit or suits at law or in equity to foreclose
this Pledge Agreement and to sell the Collateral or any portion thereof pursuant
to a judgment or decree of a court or courts having competent jurisdiction or
pursuant to a proceeding by a court-appointed receiver.  Any sale pursuant
to the provisions of this Section 4.02 shall be deemed to conform to the
commercially reasonable standards as provided in Section 9-610(b) of the
Uniform Commercial Code or its equivalent in other jurisdictions.

       

      SECTION
4.03.  Application of
Proceeds.  The Collateral
Agent shall apply the proceeds of any collection or sale of Pledged Collateral,
including any Pledged Collateral consisting of cash, as follows to the fullest
extent permitted by applicable law:

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      15

       

      FIRST, to
the payment of all reasonable costs and expenses incurred by the Collateral
Agent in connection with or reasonably related or reasonably incidental to such
collection or sale or otherwise in connection with or related or incidental to
this Pledge Agreement or any of the Obligations, including all court costs and
the reasonable fees and expenses of its agents and legal counsel, the repayment
of all advances made by the Collateral Agent (in its sole discretion) hereunder
on behalf of National Rural and any other reasonable costs or expenses incurred
in connection with the exercise of any right or remedy hereunder;

       

      SECOND,
to the payment to the Control Party
in full of the Obligations;
such payment to be for an amount certified in a Control Party
Notice delivered to the Collateral Agent as being the amount due and owing to
the Control
Party under the Obligations; and

       

      THIRD, to
National Rural, its successors or assigns, or as a court of competent
jurisdiction may otherwise direct.

       

      Upon any
sale of the Pledged Collateral by the Collateral Agent (including pursuant to a
power of sale granted by statute or under a judicial proceeding), the receipt of
the Collateral Agent or of the officer making the sale shall be a sufficient
discharge to the purchaser or purchasers of the Pledged Collateral so sold and
such purchaser or purchasers shall not be obligated to see to the application of
any part of the purchase money paid over to the Collateral Agent or such officer
or be answerable in any way for the misapplication thereof.

       

      SECTION
4.04.  Securities
Act.  In view of the
position of National Rural in relation to the Pledged Collateral, or because of
other current or future circumstances, a question may arise under the Securities
Act of 1933, as now or hereafter in effect, or any similar statute hereafter
enacted analogous in purpose or effect (such Act and any such similar statute as
from time to time in effect being called the “Federal Securities
Laws”) with respect to any disposition of the Pledged Collateral
permitted hereunder.  National Rural understands that compliance with the
Federal Securities Laws might very strictly limit the course of conduct of the
Collateral Agent if the Collateral Agent were to attempt to dispose of all or
any part of the Pledged Collateral, and might also limit the extent to which or
the manner in which any subsequent transferee of any Pledged Collateral could
dispose of the same.  Similarly, there may be other legal restrictions or
limitations affecting the Collateral Agent in any attempt to dispose of all or
part of the Pledged Collateral under applicable Blue Sky or other state
securities laws or similar laws analogous in purpose or effect.  National
Rural recognizes that in light of such restrictions and limitations the
Collateral Agent may, with respect to any sale of the Pledged Collateral, limit
the purchasers to those who will agree, among other things, to acquire such
Pledged Collateral for their own account, for investment, and not with a view to
the distribution or resale thereof.  National Rural acknowledges and agrees
that in light of such restrictions and limitations, the Collateral Agent, in its
sole and absolute discretion (a) may proceed to make such a sale whether or
not a registration statement for the purpose of registering such Pledged
Collateral or part thereof shall have been filed under the Federal Securities
Laws and (b) may approach and negotiate with a single potential purchaser
to effect such sale.  National Rural acknowledges and agrees that any such
sale might result in prices and other terms less favorable to the seller than if
such sale were a public sale without such restrictions.  In the event of
any such sale, the Collateral Agent shall incur no responsibility or liability
for selling all or any part of the Pledged Collateral at a price that the
Collateral Agent, in its sole and absolute discretion, may in good faith deem
reasonable under the circumstances, notwithstanding the possibility that a
substantially higher price might have been realized if the sale were deferred
until after registration as aforesaid or if more than a single purchaser were
approached.  The provisions of this Section 4.04 will apply
notwithstanding the existence of a public or private market upon which the
quotations or sales prices may exceed substantially the price at which the
Collateral Agent sells.

      The Collateral
Agent

       

      SECTION
5.01.  Certain
Duties and Responsibilities. 
(a)  At all times under this Pledge Agreement:

       

      (i) the
Collateral Agent undertakes to perform such duties and only such duties as are
specifically set forth in this Pledge Agreement, and no implied covenants or
obligations shall be read into this Pledge Agreement against the Collateral
Agent; and

       

      (ii) in
the absence of bad faith on its part, the Collateral Agent may conclusively
rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Collateral
Agent and substantially conforming to the requirements of this Pledge Agreement;
but in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Collateral Agent the
Collateral Agent shall be under a duty to examine the same to determine whether
or not they substantially conform to the requirements of this Pledge
Agreement.

       

      (b)  No
provision of this Pledge Agreement shall be construed to relieve the Collateral
Agent from liability for its own grossly negligent action, its own grossly
negligent failure to act, or its own willful misconduct, except
that:

       

      (i) this
Subsection shall not be construed to limit the effect of Subsection (a) of this
Section;

       

      (ii) the
Collateral Agent shall not be liable for any error of judgment made in good
faith, unless it shall be proved that the Collateral Agent was grossly negligent
in ascertaining the pertinent facts; and

       

      (iii) no
provision of this Pledge Agreement shall require the Collateral Agent to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

      (c)  Whether
or not therein expressly so provided, every provision of this Pledge Agreement
relating to the conduct or affecting the liability of or affording protection to
the Collateral Agent shall be subject to the provisions of this
Section.

       

      SECTION
5.02.  Certain
Rights of Collateral Agent. 
Except as otherwise provided in Section 5.01:

       

      (a) the
Collateral Agent may rely and shall be protected in acting or refraining from
acting upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, direction, consent, order, bond, debenture or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

       

      (b) any
request or direction of National Rural mentioned herein shall be sufficiently
evidenced by a National Rural Notice or National Rural Order;

       

      (c) any
request or direction of the Control Party mentioned herein shall be sufficiently
evidenced by a Control Party Notice or Control Party Order;

       

      (d)
whenever in the administration of this Pledge Agreement the Collateral Agent
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Collateral Agent (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on
its part, rely upon an Officers’ Certificate in the case of National Rural, and
a certificate signed by any Vice President of the Control Party in the case of
the Control Party;

       

      (e) the
Collateral Agent may consult with counsel and the advice of such counsel shall
be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in good faith and in reliance
thereon;

       

      (f) the
Collateral Agent shall be under no obligation to exercise any of the rights or
powers vested in it by this Pledge Agreement at the request or direction of
either National Rural or the Control Party pursuant to this Pledge Agreement,
unless such party shall have offered to the Collateral Agent reasonable security
or indemnity against the costs, expenses and liabilities which might be incurred
by it in compliance with such request or direction;

       

      (g) the
Collateral Agent shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture or other
paper or document, or to recompute, verify, reclassify or recalculate any
information contained therein, but the Collateral Agent, in its sole and
absolute discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Collateral Agent shall determine
to make such further inquiry or investigation, it shall be entitled to examine
the books, records and premises of National Rural, personally or by agent or
attorney;

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      18

       

      (h) the
Collateral Agent may execute any of the powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the
Collateral Agent shall not be responsible for any misconduct or negligence on
the part of any agent or attorney appointed with due care by it
hereunder;

       

      (i)
unless explicitly stated herein to the contrary, the Collateral Agent shall have
no duty to inquire as to the performance of National Rural’s covenants
herein.  In addition, the Collateral Agent shall not be deemed to have
knowledge of any Event of Default unless the Collateral Agent has received a
Control Party Notice in accordance with Section 4.01(a), and shall not be
deemed to have knowledge of the cessation of the same until such time as it
receives a National Rural Notice in accordance with Section 4.01(b);
and

       

      (j)
unless explicitly stated herein to the contrary, the Collateral Agent shall have
no obligation to take any action with respect to any Event of Default until it
has received a Control Party Notice applicable to such event in accordance with
Section 4.01(a), and the Collateral Agent shall have no liability for any
action or inaction taken, suffered or omitted in respect of any such event by it
prior to such time as the applicable Control Party Notice is delivered. 
Similarly, the Collateral Agent shall have no obligation to take any action with
respect to the cessation of an Event of Default until it has received a National
Rural Notice applicable to such event in accordance in accordance with
Section 4.01(b), and the Collateral Agent shall have no liability for any
action or inaction taken, suffered or omitted in respect of any such event by it
prior to such time as the applicable National Rural Notice is
delivered.

       

      SECTION
5.03.  Money Held
by Collateral Agent.  Money held by the Collateral Agent
hereunder need not be segregated from other funds except to the extent required
by law.  The Collateral Agent shall have no liability to pay interest on or
(except as expressly provided herein) invest any such moneys.

       

      SECTION
5.04.  Compensation and
Reimbursement. 
(a)   National Rural agrees:

       

      (i) to
pay to the Collateral Agent from time to time such reasonable compensation for
all services rendered by it hereunder as shall have been set forth in an
agreement signed by National Rural;

       

      (ii)
except as otherwise expressly provided herein, to reimburse the Collateral Agent
upon its request for all reasonable expenses, out-of-pocket costs, disbursements
and advances incurred or made by the Collateral Agent in accordance with any
provision of this Pledge Agreement (including the reasonable compensation and
the expenses and disbursements of its agents and counsel), except to the extent
any such expense, disbursement or advance may be attributable to its gross
negligence or bad faith; and

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      19

       

      (iii) to
indemnify the Collateral Agent for, and to defend and hold it harmless against,
any loss, liability or expense incurred without gross negligence or bad faith on
its part, arising out of or in connection with the acceptance or administration
of this Pledge Agreement or the performance of its duties hereunder, including
the costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder, except to the extent such loss, liability or expense may be
attributable to its gross negligence or bad faith; provided, however, that
National Rural shall have no liability under this clause for any settlement of
any litigation or other dispute effected without the prior written consent of
National Rural (such consent not to be unreasonably withheld).

       

      (b)  Any
such amounts payable as provided hereunder shall be additional Obligations
secured by the Lien hereof.  The provisions of this Section 5.04 shall
remain operative and in full force and effect regardless of the termination of
this Pledge Agreement or the Note Purchase Agreement, the consummation of the
transactions contemplated hereby, the repayment of any of the Obligations, the
invalidity or unenforceability of any term or provision of this Pledge Agreement
or the Note Purchase Agreement, or any investigation made by or on behalf of the
Collateral Agent or the Control Party.  All amounts due under this
Section 5.04 shall be payable on written demand therefor.

       

      SECTION
5.05.  Corporate
Collateral Agent Required; Eligibility.  There shall at all times be a Collateral
Agent hereunder which shall be a corporation or association organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal or State authority.  If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published.  Neither National Rural nor any Person
directly or indirectly controlling, controlled by or under common control with
National Rural shall serve as Collateral Agent hereunder.  If at any time
the Collateral Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

       

      SECTION
5.06.  Resignation and Removal;
Appointment of Successor. 
(a)  No resignation or removal of the Collateral Agent and no
appointment of a successor Collateral Agent pursuant to this Article shall
become effective until the acceptance of appointment by the successor Collateral
Agent under Section 5.07.

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      20

       

      (b)  The
Collateral Agent may resign at any time by giving written notice thereof to
National Rural.  If an instrument of acceptance by a successor Collateral
Agent shall not have been delivered to the Collateral Agent within 30 days after
the giving of such notice of resignation, the resigning Collateral Agent may
petition any court of competent jurisdiction for the appointment of a successor
Collateral Agent.

       

      (c)  If
at any time:

       

      (i)
except if an Event of Default has occurred and is continuing, National Rural, in
its sole and absolute discretion, elects to remove the Collateral Agent;
or

       

      (ii) the
Collateral Agent shall cease to be eligible under Section 5.05 or shall
become incapable of acting or shall be adjudged a bankrupt or insolvent or a
receiver of the Collateral Agent or of its property shall be appointed or any
public officer shall take charge or control of the Collateral Agent or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation,

       

      then, in
any such case, National Rural may remove the Collateral Agent by delivery of a
National Rural Order to that effect.

       

      (d)  If
the Collateral Agent shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Collateral Agent for any cause,
National Rural shall promptly appoint a successor Collateral Agent by delivering
a National Rural Notice to the retiring Collateral Agent, the successor
Collateral Agent and the Control Party to such effect.

       

      SECTION
5.07.  Acceptance
of Appointment by Successor. 
Every successor Collateral Agent appointed hereunder shall execute,
acknowledge and deliver to National Rural, the Control Party and to the retiring
Collateral Agent an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Collateral Agent shall become effective
and such successor Collateral Agent, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Collateral Agent; but, on request of National Rural, the Control
Party or the successor Collateral Agent, such retiring Collateral Agent shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor Collateral Agent all the rights, powers and trusts of the
retiring Collateral Agent, and shall duly assign, transfer and deliver to such
successor Collateral Agent all property and money held by such retiring
Collateral Agent hereunder, subject nevertheless to its Lien, if any, provided
for in Section 5.04.  Upon request of any such successor Collateral
Agent, National Rural shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Collateral Agent all such
rights, powers and trusts.

       

      No
successor Collateral Agent shall accept its appointment unless at the time of
such acceptance such successor Collateral Agent shall be eligible under
Section 5.05 hereof.

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      21

       

      SECTION
5.08.  Merger,
Conversion, Consolidation or Succession to Business.  Any corporation into which the Collateral
Agent may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Collateral Agent shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Collateral Agent, shall
be the successor of the Collateral Agent hereunder, provided such corporation
shall be eligible under Section 5.05 hereof without the execution or filing
of any paper or any further act on the part of any of the parties
hereto.

specified in Schedule II attached hereto as appropriate.  The address,
telephone number, or facsimile number for any party may be changed at any time
and from time to time upon written notice given by such changing party to the
other parties hereto. A properly addressed notice or other communication shall
be deemed to have been delivered at the time it is sent by facsimile (fax)
transmission to the party or parties to which it is given.

       

      (a)  All
National Rural Notices and National Rural Orders delivered to the Collateral
Agent shall be contemporaneously copied to the Control Party by National Rural;

      SECTION
6.02.  Waivers;
Amendment.  (a)  No failure or delay by
a party in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power.  The rights and remedies of each party hereunder are
cumulative and are not exclusive of any rights or remedies that such party would
otherwise have.  No waiver of any provision of this Pledge Agreement or
consent to any departure by any party therefrom shall in any event be effective
unless the same shall be permitted by paragraph (b) of this
Section 6.02, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given.  No notice or
demand on any party in any case shall entitle any party to any other or further
notice or demand in similar or other circumstances.

       

      (b)  Neither
this Pledge Agreement nor any provision hereof may be waived, amended or
modified except pursuant to an agreement or agreements in writing entered into

respective successors and assigns.

       

      SECTION
6.04.  Counterparts;
Effectiveness.  This Pledge

counterpart of this Pledge Agreement.

       

      SECTION
6.05.  Severability.  Any provision of this Pledge Agreement
held to be invalid, illegal or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the validity, legality and enforceability
of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.  The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS PLEDGE AGREEMENT OR THE TRANSACTIONS

EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY
OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER
PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS PLEDGE AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.07.

agreement with respect to any of the Obligations or any other agreement or
instrument relating to any of the foregoing, (b) any change in the time,

collateral, or any release or amendment or waiver of or consent under or
departure from any guarantee, securing or guaranteeing all or any of the
Obligations, or (d) any other circumstance that might otherwise constitute
a defense available to, or a discharge of, National Rural in respect of the
Obligations or this Pledge Agreement.

       

      SECTION
6.10.  Termination or
Release.  (a)  This
Pledge Agreement shall terminate on the date when the Obligations have been
indefeasibly paid in full, and at such time the Lien hereof shall be
released.

       

      (b)  Upon
any withdrawal, substitution or other disposal by National Rural of any Pledged

      SECTION
6.11.  Collateral
Agent Appointed Attorney-in-Fact.  National Rural hereby appoints the
Collateral Agent the attorney-in-fact of National Rural for the purpose of, upon
the occurrence and during the continuance of an Event of Default, carrying out
the provisions of this Pledge Agreement with respect to the Pledged Collateral
and taking any action and executing any instrument that the Collateral Agent may
deem necessary or advisable to accomplish the purposes hereof, which appointment
is irrevocable and coupled with an interest but is subject nevertheless to the
terms and conditions of this Pledge Agreement.  Without limiting the
generality of the foregoing, the Collateral Agent shall have the right, upon the
occurrence and during the continuance of an Event of Default, with full power of
substitution either in the Collateral Agent’s name or in the name of National
Rural (a) to receive, endorse, assign and/or deliver any and all notes,
acceptances, checks, drafts, money orders or other evidences of payment relating
to the Pledged Collateral or any part thereof; (b) to demand, collect,
receive payment of, give receipt for and give discharges and releases of all or
any of the Pledged Collateral; (c) to commence and prosecute any and all
suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise realize on all or any of the Pledged
Collateral or to enforce any rights in respect of any Pledged Collateral;
(d) to settle, compromise, compound, adjust or defend any actions, suits or
proceedings relating to all or any of the Pledged Collateral; (e) to
notify, or to require National Rural to notify, obligors under Pledged
Securities to make payment directly to the Collateral Agent; and
(f) subject to the second sentence of Section 4.02(a), to use, sell,
assign, transfer, pledge, make any agreement with respect to or otherwise deal
with all or any of the Pledged Collateral, and to do all other acts and things
necessary to carry out the purposes of this Pledge Agreement, as fully and
completely as though the Collateral Agent were the absolute owner of the Pledged
Collateral for all purposes; provided that nothing
herein contained shall be construed as requiring or obligating the Collateral
Agent to make any commitment or to make any inquiry as to the nature or
sufficiency of any payment received by the Collateral Agent, or to present or
file any claim or notice, or to take any action with respect to the Pledged
Collateral or any part thereof or the moneys due or to become due in respect
thereof or any property covered thereby.  The Collateral Agent and the
Control Party shall be accountable only for amounts actually received as a
result of the exercise of the powers granted to them herein, and neither they
nor their officers, directors, employees or agents shall be responsible to
National Rural for any act or failure to act hereunder, except for their own
gross negligence or willful misconduct.

    RECITALS

     

    WHEREAS,
the Purchaser, National Rural, Farmer Mac, and the Collateral Agent are parties
to a certain Pledge Agreement dated as of December 15, 2008 (“Pledge
Agreement”); and

     

    WHEREAS,
the parties have agreed to modify the Pledge Agreement as set forth
herein.

     

    NOW,
THEREFORE, in consideration of the mutual agreements herein contained, Farmer
Mac, the Purchaser, National Rural and the Collateral Agent agree as
follows:

     

    1.           Recitals.  The
foregoing Recitals are hereby incorporated by reference into this
Amendment.

    

    2.           Definitions.  Capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
them in the Pledge Agreement.

    

    3.           Amendment.

    

    (a)           The
Pledge Agreement is hereby amended by deleting the definition of Allowable
Amount in Section 1.01 in its entirety and replacing it with the
following:

    

    “Allowable Amount” on
any date means, with respect to Eligible Securities, the aggregate principal
amount of such Eligible Securities theretofore advanced thereon which remains
unpaid on such date, subject to any limitation on the Allowable Amount
applicable through the definition of “Eligible Security.”

     

    (b)           The
Pledge Agreement is hereby amended by deleting the definition of Eligible
Security in Section 1.01 in its entirety and replacing it with the
following:

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    “Eligible Security”
means a note or bond of any Eligible Member payable or registered to, or to the
order of, National Rural, (A) in respect of which (i) the outstanding
principal amount under such note or bond, together with the outstanding
principal amount of any other notes or bonds of such Eligible Member pledged
hereunder or pledged to secure any other notes or bonds issued by National Rural
to Farmer Mac or any affiliate or sold by National Rural or any affiliate to any
trust whose beneficial ownership is owned or controlled by Farmer Mac, does not
aggregate more than $35 million; provided, however, that a note or bond in
excess of $35 million may be pledged hereunder but up to $35 million principal
amount of such note or bond (considered together with any other note or bond of
such Eligible Member pledged hereunder or pledged to secure any other notes or
bonds issued by National Rural to Farmer Mac or any affiliate or sold by
National Rural or any affiliate to Farmer Mac, any affiliate or any trust whose
beneficial ownership is owned or controlled by Farmer Mac) shall be counted in
the Allowable Amount of such Eligible Security (with the amount of any such
excess recorded in Item 7 of the Certificate of Pledged Collateral in the form
of Annex A
attached hereto), (ii) no default has occurred in the payment of principal or
interest in accordance with the terms of such note or bond that is continuing
beyond the contractual grace period (if any) provided in such note or bond for
such payment and (iii) no “event of default” as defined in such note or
bond (or in any instrument creating a security interest in favor of National
Rural in respect of such note or bond), shall exist that has resulted in the
exercise of any right or remedy described in such note or bond (or in any such
instrument); (B) which is not classified by National Rural as a
non-performing loan under generally accepted accounting principles in the United
States; and (C) which otherwise satisfies the criteria set forth on Schedule I
hereto, as such Schedule I may be amended from time to time as mutually agreed
upon in writing by Farmer Mac and National Rural, with notice of any such
amendment to the Collateral Agent prior to the pledge of such Eligible
Security.

     

    (c)           The
Pledge Agreement is hereby amended by deleting Section 2.01(a) in its entirety
and replacing it with the following:

    

    (a)           National
Rural shall make available to the Control Party, within forty-five (45) days of
a pledge of the Pledged Securities in connection with an advance (or for a
longer period as National Rural and the Control Party agree), such back-up
information as is reasonably necessary in order to allow the Control Party to
confirm compliance of such Pledged Securities to the requisite criteria as
outlined herein.  Upon receipt of the back-up information, the Control
Party shall have ninety (90) days to object in writing to the inclusion of any
item of the Pledged Securities as part of the Pledged Collateral.  If
the Control Party reasonably determines that any of the Pledged Securities do
not meet the criteria for Eligible Securities, then National Rural shall have
forty-five (45) days in which to provide substitute collateral, and the timeline
specified above for National Rural to make available back-up material and
confirmation shall also apply as to the substituted collateral.

     

    (d)           The
Pledge Agreement is hereby amended by adding new Section 2.11(f) as
follows:

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    (f)           the
Allowable Amount of Pledged Collateral from Class B Members does not constitute
more than 20% of the aggregate amount of any notes or bonds: (1) pledged
hereunder; (2) pledged to secure any other notes or bonds issued by National
Rural or any affiliate to Farmer Mac or any affiliate; (3) sold by National
Rural or any affiliate to Farmer Mac or any affiliate; or (4) sold to any trust
whose beneficial ownership is owned or controlled by Farmer Mac or an
affiliate.

     

    (e)           The
Pledge Agreement is hereby amended by deleting Annex A to the Pledge Agreement
in its entirety and replacing it with Annex A attached to this
Amendment.

    

    4.           GOVERNING
LAW.    THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, FEDERAL LAW.  TO THE EXTENT FEDERAL LAW
INCORPORATES STATE LAW, THAT STATE LAW SHALL BE THE LAWS OF THE STATE OF NEW
YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED THEREIN.

     

    5.           Inconsistency with
Pledge
Agreement.  Except as otherwise amended or modified herein, the
terms, conditions and provisions of the Pledge Agreement remain in full force
and effect.  In the event of any conflict or inconsistency between the
terms of this Amendment and the Pledge Agreement, the terms of this Amendment
shall control.

    

    6.           Counterparts.  This
Amendment may be executed in two or more counterparts, each of which shall be an
original, but all of which together shall constitute one and the same
instrument.
