other  provision  hereof,  the  Trust  may  terminate,  suspend  or withdraw the
offering  of Shares whenever, in its sole discretion, it deems such action to be
desirable.
     2.     GENERAL  PROVISIONS.
            -------------------
     (a)  In  performing its duties as distributor, Curian Clearing shall act in
conformity  with  the  Registration  Statement  of  the  Trust,  and  with  any
instructions  received  from  the  Board of Trustees of the Trust (the "Board of
Trustees"),  the  requirements  of  the  Securities Act of 1933, as amended (the
"Securities  Act"),  the  Securities  Exchange  Act  of  1934,  as  amended (the
"Exchange Act"), the 1940 Act, FINRA rules, and all other applicable Federal and
State  laws  and  regulations.
     (b)  Curian  Clearing  has appointed a Chief Compliance Officer and has and
will  operate  in  compliance  with the applicable requirements of FINRA Conduct
Rule  3013, and shall cooperate fully with the Trust and its designated officers
and  Chief  Compliance  Officer in fulfilling the Trust's obligations under Rule
38a-1  under  the  1940  Act.
     (c)  Curian  Clearing  holds  itself  available  to  receive orders for the
purchase  or  redemption of Shares and shall accept or reject orders to purchase
or  redeem  such Shares on behalf of the Trust in accordance with the provisions
of the Registration Statement, and shall transmit such orders as are so accepted
to  the  Trust's  transfer  agent  promptly  for  processing.
     (d)  Curian  Clearing  shall not be obligated to sell any certain number of
Shares. Except as provided in this Agreement, no commission or other fee will be
paid  to  Curian  Clearing  in connection with the sale of Shares. The Trust and
each Fund retain the right to make direct sales of its Shares to shareholders or
to  other  persons  in  a  manner  consistent with the terms of the then current
prospectus(es)  and  statement(s)  of additional information and applicable law,
and  to  engage  in other legally authorized transactions in its Shares which do
not  involve  the  sale  of  Shares to the general public. Such transactions are
initiated  by  the  Trust  and  may  include,  but  are  not  limited  to,  the
reorganization  of the Trust or any Funds, and transactions involving the merger
or  combination  of  the  Trust  or  any  Funds  with  other  trusts  or  funds.
     (e)  Offering Price. Shares shall be offered for sale at a price equivalent
to the net asset value per share of that series or as otherwise set forth in the
Trust's  then  current prospectus(es). The Trust receives 100% of such net asset
value.  On  each  business  day on which the New York Stock Exchange is open for
business,  the  Trust  shall furnish Curian Clearing with the net asset value of
the  Shares  of  each  available  series  and class which shall be determined in
accordance  with  the Trust's then effective prospectus(es). All Shares shall be
sold  in  the  manner set forth in the Trust's then effective prospectus(es) and
statement  of  additional  information  (the  "SAI"),  and  in  compliance  with
applicable  law.
     3.  CURIAN  CLEARING  EXPENSES.  During  the term of this Agreement, Curian
------------------------  Clearing  shall  bear  all  its  expenses  incurred in
complying  with  this  Agreement,  including  the  following  expenses:
     (a)  costs  of sales presentations, preparation and delivery of advertising
and  sales  literature,  and  any  other marketing efforts by Curian Clearing in
connection  with  the  distribution  or  sale  of  Shares;
     (b)  any  compensation  paid  to employees of Curian Clearing in connection
with  the  distribution  or  sale  of  the  Shares;

     (c) development, preparation, printing and mailing of prospectuses, SAIs or
supplements,  sales  literature,  other  promotional  material describing and/or
relating to the Fund, and reports or communications which the Trust has prepared
for  distribution;  and
     (d)  Curian Clearing may make payments to sub-agents or dealers from Curian
Clearing's  own  resources,  subject  to  the following conditions: (a) any such
payments shall not create any obligation for or recourse against the Fund or any
series  or  class,  and  (b)  the  terms and conditions of any such payments are
consistent  with  the  Trust's  prospectus(es)  and applicable Federal and State
securities  laws  and  are disclosed in the Trust's prospectus(es) or SAI to the
extent  such  laws  may  require.
     4. RESERVATION OF RIGHT NOT TO SELL. The Trust reserves the right to refuse
--------------------------------  at any time or times to sell any of its Shares
for  any  reason  deemed  adequate  by  it.
     5.  TERMS AND CONDITIONS OF SALES. Shares shall be offered for sale only in
-----------------------------  those jurisdictions where they have been properly
registered  or  are exempt from registration, and only to those groups of people
which  the Board may from time to time determine to be eligible to purchase such
Shares.
     6.  ORDERS  AND  PAYMENT FOR SHARES. Orders for Shares shall be directed to
--------------------------------  the  Fund's  Transfer Agent, for acceptance on
behalf  of  the  Fund. At or prior to the time of delivery of any of the Trust's
Shares,  Curian  Clearing  shall pay or cause to be paid to the custodian of the
Fund's assets, for the Trust's account, an amount in cash equal to the net asset
value  of such Shares. Sales of Shares shall be deemed to be made when and where
accepted  by  the Fund's Transfer Agent. The Fund's custodian and Transfer Agent
shall  be  identified  in  its  prospectus(es).
     7.  PURCHASES  FOR CURIAN CLEARING'S OWN ACCOUNT. Curian Clearing shall not
---------------------------------------------  purchase  Trust Shares for Curian
Clearing's own account for purposes of resale to the public, but Curian Clearing
may  purchase  Shares  for  Curian Clearing's own investment account upon Curian
Clearing's  written  assurance  that the purchase is for investment purposes and
that  the  Shares  will  not  be  resold except through redemption by the Trust.

---------------------------  also occur in the Declaration of Trust or Bylaws of
the Trust, shall have the same meaning herein as given to such terms or words in
the  Declaration  of  Trust  or  Bylaws  of  the  Trust.

material  or  statements  except literature or advertising which conforms to the
requirements of Federal and State securities laws and regulations and which have
been  filed,  where  necessary,  with  the  appropriate  regulatory authorities.
     Curian  Clearing  shall  comply,  and  shall  require each dealer with whom
Curian  Clearing  has  entered into a dealer agreement with, to comply, with the
applicable  Federal  and  State  laws  and  regulations  where  Trust Shares are
offered,  directly  or indirectly, for sale, and shall conduct Curian Clearing's
affairs with the Trust and with dealers, brokers or investors in accordance with
FINRA Conduct Rules. Curian Clearing shall assume responsibility for the review,
and  clearance,  of  all  advertisements  and  sales literature on behalf of the
Trust.
