                        MASTER SELECTED DEALERS AGREEMENT
                        ---------------------------------


Ladies and Gentlemen:

         In connection with public offerings of securities  underwritten by W.R.
Hambrecht & Company,  LLC ("WRH"), or by a group of Underwriters  represented by
WRH (together with WRH, the "Representatives"), you and other securities dealers
(collectively,  the "Dealers") may be offered from time to time the  opportunity
to purchase a portion of such securities,  as principals, at a discount from the
public offering price representing a selling  concession or reallowance  granted
as consideration for services rendered in the distribution of such securities.

         The  Appendix  hereto  sets forth the  general  terms,  conditions  and
representations  applicable to any such purchase  where WRH is  responsible  for
reservations of securities for sale to Dealers unless WRH expressly  informs you
that such terms,  conditions and representations  shall not be applicable to any
such purchase. Acceptance of any reservation of any such securities by you, as a
Dealer, shall constitute acceptance of, and agreement to, such terms, conditions
and   representations,   together  with,  and  subject  to,  any  additional  or
supplementary  terms,  conditions  and  representations  communicated  to you in
connection with any specific offering.

         As used herein and the Appendix hereto, the term "Agreement" shall mean
this Agreement,  including the Appendix attached hereto and incorporated  herein
by reference, and, after receipt by you of written notice thereof, any amendment
or supplement hereto, plus any additional or supplementary terms, conditions and
representations  communicated to you by the  Representatives  in connection with
any offering of securities.  This Agreement shall constitute a binding agreement
between  you  and  WRH,  individually,  or  as  Representative  of  the  several
Underwriters of such securities.

         This  Agreement  supersedes any prior  understanding  you have with WRH
with respect to the subject  matter  hereof.  If the  foregoing,  including  the
general  terms,  conditions  and  representations  of the Appendix  incorporated
herein by reference is  acceptable  to you,  please sign and return the enclosed
copy of this Agreement.


                                             Very truly yours,

                                             W.R. Hambrecht & Company, LLC

                                                                        APPENDIX


            General Terms, Conditions and Representations Applicable
             in Underwritten Public Offerings of Securities Managed
                        by W.R. Hambrecht & Company, LLC


         1.   Offering  to  Dealers.   In  connection   with  public   offerings
("Offerings")   of  securities   ("Securities")   underwritten  by  underwriters
("Underwriters")  represented by W.R. Hambrecht & Company,  LLC ("WRH") alone or
in conjunction with other firms (together with WRH, the "Representatives"),  the
Underwriters may severally offer to one or more securities  dealers  ("Dealers")
the right to purchase from the Underwriters a portion of the Securities, subject
to the receipt and  acceptance  thereof by the  Underwriters  and subject to the
terms, conditions and representations set forth (a) herein, (b) in the effective
registration statement relating to the offering of the Securities and (c) in any
letter,  electronic  message,  facsimile  message  and/or  telegram  sent by the
Representatives  to Dealers  in  connection  with an offer to Dealers  expressly
informing such Dealers that such terms,  conditions and representations shall be
applicable.  Any such offer to Dealers  will be extended  only on behalf of such
Underwriters as may lawfully sell the Securities in said Dealer's state.

         Following  the  filing of a  registration  statement  with  respect  to
Securities  to  be  offered,   the   Underwriters   will  accept  by  electronic
transmission  or orally,  on behalf of  specific  brokerage  accounts  for which
Dealer acts as broker ("Accounts")  indications of interests  ("Indications") to
purchase  the  Securities.  Such  Indications  shall  set  forth  the  number of
Securities  which such  Account  proposes to purchase and the price per Security
that such Account proposes to pay in purchasing such  Securities.  No Indication
shall  be  submitted  on  behalf  of  any  Account  that  has  not  executed  or
electronically  consented to the terms and  conditions of an Electronic  OpenIPO
Participation   Agreement   substantially   in  the  form  of   Exhibit  A.  The
Representatives  shall have the right,  in their sole  discretion,  to accept or
reject any Indication for any reason. The  Representatives  shall determine,  in
their  sole  discretion,   the  point  in  time  following  the  declaration  of
effectiveness of the registration statement with respect to the Securities to be
offered at which no  additional  Indications  shall be  accepted  (the  "Auction
Close").  Following the Auction Close, the  Representatives  shall determine the
initial  public  offering  price of the  Securities  to the public (the  "Public
Offering  Price") and the  Accounts  which bid for which  Indications  have been
accepted ("Successful Bidders").

         Dealers  to whom an offer to  purchase  is made by the  Representatives
pursuant to this Agreement will be notified by the Representatives by electronic
message,  telegram or facsimile message of the method and terms of the Offering,
the time of the release of the  Securities  for sale to the  public,  the Public
Offering  Price,  the  identity  of the  Successful  Bidders  and  terms  of the
acceptance of such Indications  ("Accepted Terms"), the selling concession,  the
time at which books will be opened,  the total  amount,  if any,  of  Securities
reserved for purchase by such Dealer,  and the period of such  reservation  (the
"Transaction  Notification").  Pursuant  to  Section 9 of this  Agreement,  such
Transaction  Notification shall be deemed a supplement of this



Agreement and the terms of this Agreement  shall apply to any offering for which
a Transaction Notification is forwarded to Dealers by the Representatives.

         Acceptance  of the terms  hereof (as  supplemented  by any  Transaction
Notice)  constitutes an obligation on the part of each Dealer to purchase,  upon
the terms and conditions hereof (as supplemented by any Transaction Notice), the
amount of  Securities  reserved  and  accepted by such Dealer and to perform and
observe all the terms and conditions hereof.

         2.  Offering  by Dealers.  Immediately  upon  receipt of the  telegram,
letter or  transmission  referred  to in clause  (c) of the first  paragraph  of
Section  1  hereof,  Dealers  may  reoffer  the  Securities  purchased  by  them
hereunder,   subject  to  receipt  and  acceptance  of  the  Securities  by  the
Underwriters, and upon the other terms, conditions and representations set forth
herein and in the effective  registration statement relating to such Securities.
Each Dealer  hereby  represents  and agrees that such Dealer  shall  reoffer the
Securities to  Successful  Bidders  pursuant to the Accepted  Terms and will not
offer any of the Securities for sale to other  prospective  purchasers except as
consented to in writing by the  Representatives.  Securities purchased hereunder
or are to be offered to the public at the Public Offering Price.  You agree that
any Securities  purchased from you in connection  with your  participation  as a
Dealer will be evidenced by an electronic or written  confirmation setting forth
the Accepted  Terms and otherwise  meeting the  requirements  of the  applicable
federal  regulations,  and be subject to the terms and  conditions  set forth in
such confirmation and in the Prospectus.

         With the consent of the  Representatives,  Dealers and Underwriters may
deal in Securities  with each other at the Public  Offering Price less an amount
not exceeding the concession to Dealers.  After the initial public offering, the
Representatives are authorized to vary the Public Offering Price, concession and
other selling terms of the Securities.

         3.  Payment and  Delivery.  The  Securities  offered to and accepted by
Dealers are to be paid for at the Public Offering Price prior to 6 o'clock a.m.,
Pacific  time, on the Closing Date, as defined in the agreement for the purchase
of the Securities by the Underwriters  (the  "Underwriting  Agreement").  Unless
otherwise indicated,  such payment is to be made at the Clearing Agent' offices,
[ADDRESS],  by certified or bank  cashier's  check payable in next day funds (or
such  other  funds  as the  Representatives  may  advise),  to the  order of the
Representatives against delivery of such Securities.  Delivery of any Securities
purchased by Dealers  shall be made  through the  facilities  of The  Depository
Trust  Company if  Dealers  are  members  thereof,  unless  the  Representatives
otherwise notifies Dealers in its discretion. If a Dealer is not a member of The
Depository  Trust Company,  such delivery shall be made through a  correspondent
who is such a member,  and such Dealer will  advise the  Clearing  Agent and the
Representatives  of the  name of such  bank or  correspondent  at least 48 hours
prior to the Closing Date.

         4.  Termination  of  the  Offering.  With  respect  to  any  particular
Offering,  the terms and conditions of this Agreement  shall  terminate upon the
earlier  of notice to you from the  Representatives  of (a)  termination  of the
Offering pursuant to the termination provisions of the underwriting agreement or
any other agreement in connection with the  distribution;  (b) the completion of
the distribution pursuant to such Offering; or (c) if not previously terminated,
on



the  thirtieth  (30th)  day  after the date upon  which the  Underwriters  first
commence  accepting  Offers as set forth in Section 1.  Unless the  Offering  is
terminated  pursuant to clause (a) of this  paragraph,  promptly  following such
termination, there shall become payable to each Dealer the selling concession on
all Securities  purchased by such Dealer  pursuant to the terms hereto and which
have not been purchased or contracted for by the Underwriters in the open market
or  otherwise  (except  pursuant to the second  paragraph  of Section 5 hereof),
during the term of such  Offering  for the account of one or more of the several
Underwriters.

         5.  Obligations  and Positions of Dealers.  Dealer agrees in reoffering
the  Securities  to  comply  with all  applicable  requirements  of the  federal
securities laws and all applicable rules and regulations promulgated thereunder.
If any Dealer  fails to pay for the  Securities  offered to and accepted by such
Dealer or fails to perform any of such Dealer's other obligations hereunder, the
Representatives  may, in the  Representatives'  discretion  and without  demand,
notice or legal  proceedings,  and in addition to any and all remedies otherwise
available to the  Representatives  and to the other  several  Underwriters,  (a)
terminate any right or interest on such Dealer's  part,  and (b) at any time and
from time to time sell,  without  notice to such Dealer,  any of the  Securities
then held for such  Dealer's  account  at public  or  private  sale (i) to other
Dealers on terms substantially  equivalent to those set forth herein, or (ii) if
in the sole discretion of the Representatives  circumstances so warrant, to such
parties  and at such price or prices and upon such terms and  conditions  as the
Representatives  may deem  fair,  and apply the net  proceeds  so  realized,  as
determined by the Representatives,  toward payment of any obligations in respect
of which such Dealer is in default, and,  notwithstanding any action taken under
(a) or (b) above, or both, such Dealer shall remain liable to the  Underwriters,
severally,  to  the  extent  of the  Dealers'  respective  interests,  or at the
Representatives' election, to the Representatives for the respective accounts of
the several  Underwriters to a like extent,  for all loss and expense  resulting
from such Dealer's  default.  At any such sale or sales, any of the Underwriters
may, for such  Underwriter's own account or for the account of any other person,
become the purchaser of any Securities so sold,  free from any right or interest
on any Dealer's part in such Securities.  A default by one or more Dealers shall
not release any other Dealer from any obligation hereunder.

         Dealers agree to advise the  Representatives,  upon request,  as to the
number of the  Securities  accepted  by such Dealer in any  particular  Offering
which then  remain  unsold;  and  Dealers  further  agree,  upon  request of the
Representatives,  to sell to the  Representatives for the account of one or more
of the Underwriters such number of such unsold Securities as the Representatives
may specify  (in order to enable the  Representative  to deliver the  Securities
sold by or for the  account of one or more of the several  Underwriters)  at the
Public Offering Price less an amount  determined by the  Representatives  not in
excess of the concession to Dealers.

         Dealers (a) are not authorized by any of the  Underwriters  to give any
information or to make any  representations  in connection  with the offering or
sale of the Securities other than those contained in the prospectus  relating to
such  Securities;  (b)  are  not  authorized  to act  as  agent  for  any of the
Underwriters  when  offering  the  Securities  to the public or  otherwise;  (c)
acknowledge  and agree that the issuer is not authorized to give any information
or to make any  representations  to Dealers in  connection  with the offering or
sale of the Securities other than those contained in the effective  registration
statement relating to the Securities;  and (d) agree not



to give any  information  or make any  representations  in  connection  with the
offering or sale of the Securities  other than those contained in the prospectus
relating  to such  Securities  on behalf  of the  issuer or act as agent for the
issuer  when  offering  the  Securities  to the  public  or  otherwise.  Nothing
contained  herein shall  constitute the Dealers as an association or partnership
with  the  Underwriters,  the  Representatives,  WRH  or  each  other,  or as an
unincorporated business or other separate entity.

         The  Representatives  undertake in any offering of  Securities  to make
available copies of prospectuses (i)  electronically  by reference to an address
on the World Wide Web where such  prospectuses  shall be posted and available to
be printed  and (ii) by mail upon  request by Dealers for the benefit of persons
requesting printed  prospectuses and as otherwise required by federal securities
laws and regulations. Each Dealer undertakes to deliver such prospectuses to all
persons to whom Securities are reoffered or as otherwise required by federal and
applicable  state  securities  laws and regulations in accordance with such laws
and  regulations.  Each Dealer  represents  that it is familiar with Rule 15c2-8
under the Securities  Exchange Act of 1934, as amended (the "1934 Act") relating
to the  distribution of preliminary and final  prospectuses and agrees that such
Dealer will comply therewith.

         Each Dealer hereby  represents  that it is (i) a member of the National
Association of Securities  Dealers  ("NASD") in good standing (a "NASD Member");
(ii) a foreign bank, broker, dealer or institution  ineligible for membership in
the NASD (a "Foreign  Bank") or (iii) a bank that is not a member of the NASD (a
"Non-Member  Bank").  Each Dealer  that is an NASD Member  agrees that in making
sales of Securities,  such Dealer will comply with all  applicable  rules of the
NASD.  Each Dealer that is a Foreign  Bank or  Non-Member  Bank agrees to comply
with  Conduct  Rules  2730,  2740 and 2750 of the  NASD and to  comply  with the
requirements  of the  NASD's  Interpretation  with  Respect to  Free-Riding  and
Withholding as if such Foreign Bank or Non-Member Bank were an NASD Member. Each
Dealer that is a Foreign Bank agrees not to offer or sell any  Securities in the
United States of America except through the  Representatives and in making sales
of Securities  agrees to comply with Conduct Rule 2420 of the NASD as it applies
to  brokers  and  dealers  in  foreign  jurisdictions.  Each  Dealer  that  is a
Non-Member Bank agrees to comply with NASD Conduct Rule 2420 as though it were a
NASD  Member and not to accept any  portion  of the  management  fee paid to the
Representatives  with respect to the offering of any  Securities or, except with
respect to "exempted  securities"  within the meaning of Section 3(a)(12) of the
Securities  Exchange Act of 1934, purchase any Securities at a discount from the
Public  Offering Price from any  Underwriter  or Dealer or otherwise  accept any
selling concession,  discount or other allowance form any Underwriter or Dealer,
which in such case is not permitted under the NASD's Rules of Fair Practice.

         Each Dealer represents that such Dealer will not effect any transaction
in violation of the provisions of Regulation M under the 1934 Act, applicable to
a  particular  Offering,  and each  Dealer  agrees  that it will not,  until the
completion of the distribution by it of the Securities in a particular  Offering
pursuant to this Agreement,  bid for,  purchase,  sell or deal in, or attempt to
induce  others to purchase such  Securities,  except (i) as provided for in this
Agreement,   the  Underwriting   Agreement  or  as  otherwise  approved  by  the
Representatives or (ii) in brokerage transactions not involving the solicitation
of a customer's order.


         Each Dealer  agrees  that such  Dealer  will not  confirm  sales to any
Account  over which such Dealer has  discretionary  trading  authority,  or make
allocations  of the type  discussed in Release No. 4150 under the Securities Act
of 1933, as amended.

         Each Dealer  agrees that such Dealer  shall be solely  responsible  for
determining the suitability of any Account  submitting an indication of interest
and that such Dealer will  undertake  such steps as are  necessary  to determine
that each  Offering is a suitable  investment  for each  Account with respect to
whom an indication of interest is submitted to WRH with respect to such Offering
and that no sales of  Securities  with respect to any Offering  shall be made to
any Account for which an investment in such Securities is not suitable.

         6. Blue Sky Matters.  The  Representatives  will advise  Dealers of the
jurisdictions  where counsel for the  Underwriters  has advised the Underwriters
that the  Securities  have been  qualified for public  offering and sale, or are
exempt from  qualification  under  applicable Blue Sky or state securities laws.
The Representatives shall, however, be under no responsibility whatsoever to any
Dealer with  respect to the right of such Dealer to sell the  Securities  in any
jurisdiction.  Each Dealer, including,  without limitation,  each Foreign Dealer
acknowledges  that no action will be taken by the  Underwriters or the issuer to
permit a public offering in any jurisdiction  other than the United States where
action would be required for such purpose.

         7.  Limitation  of  Liability.  The  Representatives  shall  have  full
authority  to take such action as they deem  advisable in respect of all matters
pertaining to the offering or arising hereunder. Neither the Representatives nor
any Underwriter shall be under any liability,  except for their own want of good
faith, for or in respect of the validity of, or title to, any of the Securities;
the form of, or the statements contained in, or the validity of the prospectuses
or any amendment or supplement thereto,  any document  incorporated by reference
therein  or any other  instruments  executed  by or on  behalf of the  issuer or
seller of the  Securities  or others;  the form or validity of the  Underwriting
Agreement or this Agreement; the delivery of the Securities,  the performance by
the  issuer or seller of the  Securities  or others of any  agreement  on its or
their part; the qualifications of the Securities for sale or the legality of the
Securities  for  investment  under  the  laws  of any  jurisdiction;  any act or
ommission,  or any matter in  connection  with any of the  foregoing;  provided,
however,  that  nothing  in this  paragraph  shall  be  deemed  to  relieve  the
Representatives  or any  Underwriter  from  any  liability  imposed  by  federal
securities  laws or liability  related to obligations  expressly  assumed by the
Underwriters in this Agreement.

         8. Notices. All communications from Dealers should be addressed to W.R.
Hambrecht & Company,  LLC, 550  Fifteenth  Street,  San  Francisco,  CA,  94103,
Attention:  Mr. Robert Eu. Any notice from the Representatives to a Dealer shall
be deemed to have been duly authorized by the Underwriters and to have been duly
given if mailed or telegraphed  to such Dealer at the address  appearing in this
Agreement or delivered  electronically  to the e-mail address  appearing in this
Agreement.

         9.  Amendment.  This  Agreement may not be amended  without the written
consent of both  parties  hereto;  provided,  however,  that with respect to the
information specified in the third paragraph of Section 1, this agreement may be
supplemented  by  WRH by  delivery  to you of a



Transaction  Notice. Any such supplement or amendment to this Agreement shall be
effective with respect to any Offering to which this Agreement applies after the
date of such supplement or amendment.

         10. Termination. This Agreement shall continue in full force and effect
until  terminated by either party by five business  days' written  notice to the
other, provided that, if this Agreement has become effective with respect to any
offering of Securities,  this Agreement shall remain in full force and effect as
to such  offering  and shall  terminate  as  otherwise  provided  in  Section 4.
Notwithstanding  any distribution  and settlement of accounts,  Dealers shall be
liable for the proper  proportion of any transfer tax or other  liability  which
may be  asserted  against  the  Representatives  or any of the  Underwriters  or
Dealers  based upon the claim that the  Dealers,  or any of them,  constitute  a
partnership,  an  association,  an  unincorporated  business  or other  separate
entity.

         11.  Governing Law. This Agreement shall be governed by the laws of the
State of California.





                         OpenIPO Participation Agreement

Information  by providing you with notice which directs you to an Internet world
wide web address ("URL") where the OpenIPO Information is posted and may be read
and printed.  The provision of any such notice (a "URL Notice")  shall be deemed
effective delivery of the OpenIPO Information  referenced in such URL Notice and
the Underwriters and Broker shall be under no further obligation to deliver such
OpenIPO Information except as specifically set forth herein. The Underwriters or
Broker may, in their discretion, provide you with URL Notice by mail, electronic
mail,  notification  set forth in this  Agreement  or  notification  by WRHCo or
Broker upon submission of an OpenIPO Bid (as defined below).  You hereby consent
to delivery of OpenIPO  information through URL Notice and acknowledge that such
delivery  shall  constitute  good and  effective  delivery to you of the OpenIPO
Information referenced in the URL Notice whether or not you access or review the
OpenIPO information referenced in the URL Notice.

YOU ACKNOWLEDGE  AND UNDERSTAND  THAT THE PRELIMINARY AND FINAL  PROSPECTUS WITH
RESPECT  TO  EACH  OFFERING  SHALL  BE  AVAILABLE  AT  THE  FOLLOWING   WEBSITE:

you. You may make your request to Broker or to WRHCo,  as applicable.  You agree
that  despite  any such  request  and  compliance  with any such  request by the
Underwriters  or Broker,  electronic  delivery of such  OpenIPO  Information  or
delivery by URL Notice  shall  constitute  good and  effective  delivery of such
OpenIPO  Information  and  that  the  fact  that a paper  copy  of such  OpenIPO
Information was requested or delivered shall not imply the contrary.

2. OpenIPO Bids.  With respect to public  offerings of securities  ("Offerings")
within the  OpenIPO  System,  after a  registration  statement  relating to such
offering has been filed,  you may be permitted  to enter a  conditional  bid (an

you place a OpenIPO Bid, you shall be informed by Broker or WRHCo,  prior to the
submission of your OpenIPO Bid to WRHCo, as to the first date after which Broker
and  WRHCo may  refuse  to accept  any  additional  OpenIPO  Bids (the  "Auction
Close").  The Auction  Close may occur upon such  indicated  date or at any time
thereafter, but in no event shall the Auction Close occur prior to the effective
date of the registration statement relating to such Offering.

Posting  of a notice  of an  Offering  through  the  OpenIPO  System  shall  not
constitute an offer to sell or the  solicitation  of an offer to buy securities.
No OpenIPO Bid may be accepted and no part of the purchase price can be received
until the registration statement relating to such Offering has become effective,
and any OpenIPO Bid may be withdrawn, modified or revoked, without obligation or
commitment  of any kind,  at any time  prior to notice of its  acceptance  after
effectiveness of such  registration  statement and the Auction Close. An OpenIPO
Bid submitted to broker will involve no obligation or commitment of any kind.

OpenIPO  Bids  shall  include  the  number of  securities  which you  propose to
purchase  and  the  price  per  security  which  you  propose  to pay  for  such
securities.  The  price  per  share  included  in an  OpenIPO  Bid  shall  be in
increments of at least 1/32 of a dollar. No OpenIPO Bid that alone, or that when
cumulated  with other OpenIPO Bids  submitted and not canceled on behalf of your
Account,  would  constitute a bid for 10% or more of the shares available in the
Offering will be accepted.  All OpenIPO Bids that alone,  or that when cumulated
with other  OpenIPO Bids  submitted  and not canceled on behalf of your Account,
constitute a bid for in excess of 1% of the shares  available in the Offering (a
"Large  Quantity  Bid") shall be subject to WRHCo's  rules with respect to Large
Quantity Bids as set forth below.

Each  OpenIPO  Bid  will be  authorized  by you and  subject  to the  terms  and
conditions  of this  Agreement.  Any  OpenIPO  Bid  accepted  by Broker  and the
Underwriters  shall be accepted on the basis that an actual purchase is intended
and that you shall be obligated,  in every case, to pay for the  securities  bid
for  upon  closing  of the  sale of the  securities  bid for on  behalf  of your
Account. The execution of a firm commitment underwriting agreement by WRHCo will
be a condition to your obligation to pay for any securities.

If an OpenIPO Bid is submitted by you with respect to a particular Offering, and
such OpenIPO Bid includes a price in excess of the "Clearing  Price" (as defined
below),  Broker has agreed with WRHCo to attempt to accept such  OpenIPO Bid and
transact  for the sale of all or a  portion  of the  securities  which  you have
offered to purchase as provided in such OpenIPO Bid at the "Offering  Price" (as
defined  below) prior to sale of such  securities to other  parties,  subject to
adjustments  consented to by the Underwriters.  Without limiting their rights as
set forth  herein to alter the method of  allocation  and pricing and subject to
their  rights with  respect to Large  Quantity  Bids (as set forth  below),  the
Underwriters  and  Broker  shall use  reasonable  efforts to accept in whole all
OpenIPO Bids setting  forth a price in excess of the Clearing  Price (as defined
below) and accept in part all OpenIPO  Bids  setting  forth a price equal to the
Clearing  Price.  Notwithstanding  the  foregoing,  you  hereby  agree  that the
submission of an OpenIPO bid on behalf of your Account in no way entitles you to
purchase the securities offered and that Broker and the Underwriters reserve the
right and  authority,  in their  discretion  and without  notice,  to reject any
OpenIPO Bid that


                                       2


the  Underwriters  deem  manipulative  of the OpenIPO  System,  disruptive  with
respect to a particular Offering,  disruptive to the securities market,  unusual
in size, type or credit risk or which the Underwriters  otherwise deem necessary
or beneficial to facilitate the orderly completion of the Offering.  In addition
the Underwriters reserve the right and authority to, in their own discretion and
without notice,  alter the proposed method of allocation and allocate securities
on a different basis if they deem necessary to facilitate the orderly completion
of the Offering.

Broker may require that your Account  contain  available  funds or cleared funds
equal to or in excess of the aggregate  purchase price reflected by your OpenIPO
Bids. Broker reserves the right and authority to, in its sole discretion, reject
any OpenIPO Bid received  without  requisite  funds in your Account prior to the
Auction close or, if not rejected,  and additional funds are not submitted prior
to settlement, to liquidate your Account.

The "Clearing Price" with respect to any particular  Offering shall be the price
at which sufficient OpenIPO Bids have been submitted to WRHCo to sell all of the
securities proposed to be sold in such Offering.  You understand and acknowledge
that the price at which the  securities  in any  Offering are sold to the public
(the  "Offering  Price") may be less than the  Clearing  Price.  Any OpenIPO Bid
submitted by you that  includes a price in excess of the  Offering  Price may be
accepted by Broker (at the Offering Price), in whole or in part,  whether or not
such OpenIPO Bid is in excess of the Clearing Price.

3.  Modification  and  Cancellation  of OpenIPO  Bids.  Any request to cancel or
modify an OpenIPO  Bid will only be  effected  if such  request is  received  by
Broker and transmitted to the  Underwriters  prior to time at which your OpenIPO
Bid is accepted.

4. Applicable Rules and Regulations.  Broker's processing of any OpenIPO Bid and
all  transactions  on behalf of your Account with respect to the OpenIPO  System
shall be subject to Broker's rules and regulations and the rules and regulations
of WRHCo as managing underwriter of the Offering, which are subject to change at
any time  without  notice.  The rules and  procedures  applicable  to use of the
OpenIPO System shall be made available to you at any time upon request to Broker
and may be delivered to you in the same manner as any other OpenIPO  Information
(including by URL Notice).  In addition,  where applicable,  the transactions in
your  Account  with  respect  to the  OpenIPO  System  shall be  subject  to the
provisions of the  Securities Act of 1933, as amended,  the Securities  Exchange
Act of 1934, as amended,  and to the rules and regulations of the Securities and
Exchange  Commission,  the Board of Governors of the Federal Reserve System, the
National   Association   of   Securities   Dealers  and  any  other   applicable
self-regulatory organization ("Applicable Regulations").

Violation  by you of  Applicable  Regulations,  (including  without  limitation,
restrictions  on  "Free-Riding"  in  violation  of  Regulation  T of the Federal
Reserve  Board)  may  result in  restrictions  being  placed on your  ability to
participate in Offerings through OpenIPO System.

5. Large Quantity Bids. Without limiting any of the foregoing,  the Underwriters
and the Broker shall have the right to accept any Large Quantity Bid in part and
limit the allocation of securities  with respect to any Large Quantity Bid to an
amount  less than the total  number of shares  requested  pursuant to such Large
Quantity  Bid,  if in the sole  discretion  of the  Underwriters,  such  partial
allocation of shares is necessary to facilitate a reasonable public distribution
of the securities available in the Offering.

6. Transactions and Settlement.  The purchase and sale of securities through the
OpenIPO System are settled on "settlement  date," which  generally  shall be the
third  business  day after an  OpenIPO  Bid is  accepted  by  Broker  and or the
Underwriters.  If funds for settlement are not available in the Account and your
OpenIPO bid is accepted,  your payment via wire or personal check or money order
must  immediately  be  submitted  to  Broker.  The  payment  must be sent to the
Broker's  clearing  firm if the broker uses a clearing  firm.  If payment is not
received,  at Broker's discretion,  your Account may be liquidated without prior
notice.  In the  event  your  Account  is  liquidated,  you will be  liable  for
resulting  losses  and all  associated  costs  incurred  by  Broker  and/or  the
Underwriters.

7.  Restrictions.  For their  protection,  the Underwriters or Broker may at any
time, at their discretion and without prior notice to you, place restrictions on
your ability to participate in the OpenIPO System.

                                       3


8. Agency.  You  understand  that with respect to Offerings  through the OpenIPO
System,  Broker is acting as a principal.  Broker will  purchase the shares from
WRHCo and sell them to you.

9. Electronic Products and Services. All products and services currently offered
or offered in the future by Broker or WRHCo which, through the use of electronic
or interactive  data  communications,  allow you (i) to communicate with Broker,
the Underwriters or any authorized  service provider with respect to the OpenIPO
System,  (ii) to obtain  information  with  respect to an  Offering  through the
OpenIPO System, or (iii) to buy securities in any Offering  conducted within the
OpenIPO  System  through  Broker  (each  an  "EPS")  shall be  utilized  only in
accordance with this Agreement.

You  hereby  agree that you shall be the only  authorized  user of any EPS under
this   Agreement   and  that   you   shall  be   solely   responsible   for  the
telecommunications  costs (including  internet access fees) incurred directly by
you  in   accessing   any  EPS.  You  shall  be  solely   responsible   for  the
confidentiality of any user name,  password or other alpha-numeric code or other
device required to participate in the OpenIPO System or otherwise access any EPS
("Passwords").  You  understand  that you  shall be solely  responsible  for all
OpenIPO Bids submitted on behalf of your account utilizing such Passwords.

If you become  aware of any  unauthorized  use of your  Account  with respect to
transactions  through the OpenIPO System, you shall immediately notify WRHCo and
Broker in writing or via E-mail.  Upon receipt of such notice,  Broker and WRHCo
shall take  reasonable  steps to stop any activity in your Account,  but neither
Broker, WRHCo, the Underwriters nor any of their respective managers, directors,
officers, employees, agents, affiliates,  representatives or subsidiaries can or
will have any  responsibility  or  liability to you or to any other person whose
claim may arise  through  you for any claims  with  respect to the  handling  or
mishandling  of any  transaction  in  the  OpenIPO  System  resulting  from  the
unauthorized  use of your  Account.  If you  notify  Broker  only,  WRHCo is not
responsible for any unauthorized use of your Account. WRHCo, furthermore, is not
responsible for any acts of Broker relating to your Account.

WRHCo or Broker may modify or discontinue any EPS without prior notice.

NEITHER  WRHCo,  THE  UNDERWRITERS,  BROKER  NOR  THEIR  RESPECTIVE  AFFILIATES,
MANAGERS,   DIRECTORS,   OFFICERS,   EMPLOYEES,   AGENTS,   REPRESENTATIVES   OR
SUBSIDIARIES  SHALL BE LIABLE  FOR ANY  DAMAGES,  WHETHER  DIRECT  OR  INDIRECT,
(INCLUDING,  WITHOUT LIMITATION,  INCIDENTAL,  SPECIAL OR CONSEQUENTIAL DAMAGES)
THAT  RESULT  FROM  INCONVENIENCE,   DELAY  OR  LOSS  OF  THE  USE  OF  ANY  EPS
NOTWITHSTANDING  THE  FACT  THAT  BROKER  OR  WRHCo  HAS  BEEN  ADVISED  OF  THE
POSSIBILITY  OF ANY SUCH  DAMAGES.  WRHCo  DOES NOT MAKE ANY  WARRANTY  OR OTHER
ASSURANCES AS TO THE OPERATION OR FUNCTIONALITY OF ITS WEB SITE, ACCESS TO WHICH
MAY BE  INTERRUPTED,  RESTRICTED  OR DELAYED  FROM TIME TO TIME FOR A VARIETY OF
REASONS WHICH ARE BEYOND ITS CONTROL.

10.  Eligibility.  You  hereby  acknowledge  that WRHCo or Broker may notify you
through  electronic  mail  or  otherwise  of  opportunities  to  participate  in
Offerings  through  the  OpenIPO  System.  You  understand  that  Offerings  are
considered to be high risk  investments.  You agree that such notices from WRHCo
or Broker of  opportunities  to  participate  in  Offerings  through the OpenIPO
system  are  not   intended  to  be,  and  shall  not  be   considered   to  be,
recommendations  by WRHCo or Broker that Offerings in general or any Offering in
particular is a suitable  investment for you. On the contrary,  you  acknowledge
and agree that  investing  in  Offerings  is  speculative  and highly  risky and
therefore  only  appropriate  for investors who desire to take and can bear such
risks.  You further  represent and warrant that you have  disclosed to Broker in
your account  application  or otherwise if you are an employee of any securities
exchange, or of any corporation in which any securities exchange owns a majority
of the capital  stock,  or a member of any exchange,  or of a member firm or any
securities  exchange or the National  Association  of Securities  Dealers,  Inc.
("NASD"), or of a bank, trust company, insurance company, or of any corporation,
firm, or individual engaged in the business of dealing,  either directly or as a
broker or principal,  in


                                       4


securities,  bills of exchange,  acceptances or other forms of commercial paper,
or if you are a member of the  immediate  family of any such person.  You hereby
agree to notify  Broker in writing if you or a member of your  immediate  family
become or becomes so  affiliated  and to furnish  Broker such  information  that
Broker requests to verify or confirm such representation. You represent, warrant
and agree that you will not submit an OpenIPO Bid with  respect to any  Offering
which is not a suitable investment for you based on your investment  objectives,
your other  securities  holdings and your  financial  situation  and needs.  You
hereby  certify,  nevertheless,  that you have  furnished  Broker with  personal
information about your investment objectives, your other securities holdings and
your financial  situation and needs,  and that such  information is now accurate
and current,  and will be accurate  and current,  as of the date of each OpenIPO
Bid. You agree to promptly furnish Broker with any changes in such  information.
If applicable,  you also represent,  warrant and agree that you will not open an
Account  with  Broker or submit an OpenIPO  Bid for which you have not  obtained
approval  from  your  compliance  officer  prior to  opening  such  Account  and
submitting  such OpenIPO Bid. You agree,  furthermore,  that Broker or WHRCo may
reject your bid in its entirety or reduce the amount of shares for which you bid
in either of their respective  discretion based on the information you furnished
to Broker.

11. Severability. If any provision of this Agreement is held to be invalid, void
or  unenforceable by reason of any law, rule,  administrative  order or judicial
decision,  that  determination  shall not affect the  validity of the  remaining
provisions of this Agreement.

12. Waiver. Except as specifically permitted in this Agreement,  no provision of
this Agreement can be, nor be deemed to be, waived, altered, modified or amended
unless agreed to in writing signed by an authorized officer of Broker and WRHCo,
respectively.

13.  Successors.  You hereby agree that this  Agreement and all the terms hereof
shall  be  binding  upon  your  heirs,   executors,   administrators,   personal
representatives  and  assigns.  This  Agreement  shall  inure to the  benefit of
Broker,  WRHCo, the Underwriters  and their respective  successors,  assigns and
agents.

14.  Captions.  The caption of each provision hereof is for convenience only and
shall not be deemed to modify or qualify  any of the rights or  obligations  set
forth or be used to construe or interpret any of the provisions hereunder.

15.  Arbitration.

A.       The following general provisions apply to all arbitrations  pursuant to
         the arbitration provisions of this section:

               (i)           Arbitration is final and binding on the parties.

               (ii)          The  parties  are  waiving   their  right  to  seek
                             remedies  in  court,  including  the  right to jury
                             trial.

               (iii)         Pre arbitration discovery is generally more limited
                             than and different from court proceedings.

               (iv)          The  arbitrators  award is not  required to include
                             factual findings or legal reasoning and any party's
                             right to appeal or to seek  modification of rulings
                             by the arbitrators is strictly limited.

               (v)           The panel of arbitrators  will typically  include a
                             minority of arbitrators  who were or are affiliated
                             with the securities industry.

B.       You  agree  that  the  following   conditions  apply  to  any  and  all
         controversies  arising  between You and Broker or WRHCo,  and/or any of
         their respective managers,  directors,  officers,  controlling persons,
         agents,  employees,  representatives  or agents  with  respect  to this
         Agreement or to any Offering: All controversies which may arise between
         You and/or Your agents, employees or representatives,  and WRHCo and/or
         Broker,  and/or  WRHCo's or Broker's  respective  managers,  directors,
         officers,  controlling persons,  employees,  representatives or agents,
         concerning any transaction, the construction,  performance or breach of
         this Agreement, or relating to any OpenIPO Bid or any Offering, whether
         such  transaction  or  OpenIPO  Bid  was  entered  into  prior,  on  or
         subsequent to the date hereof,  shall be determined by arbitration held
         pursuant to the then current Code of Arbitration Procedure of the NASD.
         Arbitration  must be  commenced  by  service  upon the  other


                                       5


         party or  parties  of a written  demand  for  arbitration  or a written
         notice of intention to arbitrate.  This agreement to arbitrate shall be
         specifically enforceable under prevailing law and procedures, the award
         rendered by the arbitrators shall be final, and judgment may be entered
         upon it in any court having jurisdiction over the parties.  Counsel can
         advise you on how this  provision may affect you.

C.       This agreement to arbitrate constitutes a waiver of the right to seek a
         judicial  forum  unless  such a waiver  would be void under the federal
         securities laws.

D.       No  person  shall  bring  a  putative  or  certified  class  action  to
         arbitration,  nor seek to enforce any pre-dispute arbitration agreement
         against any person who has initiated in court a putative  class action;
         or who is a member  of a  putative  class  who has not opted out of the
         class with  respect to any claims  encompassed  by the  putative  class
         action until:

               (i)         the class  certification is denied;
               (ii)        the class is decertified; or
               (iii)       the customer is excluded from the class by the court.

         Such  forbearance  to  enforce  an  agreement  to  arbitrate  shall not
constitute  a waiver of any  rights  under this  agreement  except to the extent
stated  herein.  

The undersigned  (referred to as "You" in this Agreement)  acknowledges that the
undersigned  has read and  understands  this  Agreement and that this  Agreement
contains  a  predispute  arbitration  clause at Section 15 on pages 5 and 6. The
undersigned acknowledges receipt of a copy of this Agreement.
