         This   Statement  on  Schedule  13D  (this   "Statement")   relates  to
transactions  effected on August 13, 1997 (the  "Reporting  Date") and  reflects
information as of August 17, 1999.  Pursuant to Rule 13d-1(c)  promulgated under
the  Securities  Exchange  Act  of  1934,  as  amended  (the  "1934  Act"),  the
Kiskiminetas  Springs  School  (the  "Reporting  Person")  is  filing a  related
Statement  on  Schedule  13G  immediately  after the  filing of this  Statement.
Information  contained  in this  Statement  regarding  persons  other  than  the
Reporting Person is furnished to the best knowledge of the Reporting Person.

ITEM 1.  SECURITY AND ISSUER.

         This Statement  relates to the shares of Common Stock,  par value $1.00
per share (the "Common Stock"), of Coyote Network Systems,  Inc. (the "Issuer").
The principal  executive  offices of the Issuer are located at 4360 Park Terrace
Drive, Westlake Village, CA 91361.

ITEM 2.  IDENTITY AND BACKGROUND.

         This  Statement is being filed by the Reporting  Person.  The Reporting
Person  is  a  Pennsylvania  non-profit  educational  institution  that  has  an
endowment  composed of the shares of the Issuer's Common Stock and certain other
securities.  The Reporting Person currently holds 145,700 shares of Common Stock
in an  account at  PaineWebber  Incorporated  (the  "PaineWebber  Account")  and
864,510  shares of Common Stock in an account at Piper  Jaffray Inc. (the "Piper
Jaffray Account").

         Since  March 1999,  the voting  power and the  investment  power of the
Reporting Person over the shares of Common Stock held in the PaineWebber Account
and the Piper Jaffray Account has been vested solely in the Finance Committee of
the Board of Trustees of the Reporting Person (the "Finance  Committee"),  which
is exercised by the approval of the majority of the members thereof. The Finance
Committee is composed of seven members. The Members of the Finance Committee are
Alan J. Andreini,  Michael Yukevich,  Jr., John A. Pidgeon, Allen R. Glick, Carl
L. Kalnow,  James P. Moore, Jr., Maynard H. Murch IV, and Janice Fuelhart.  Such
decisions of the Finance  Committee are then carried out by certain  individuals
authorized to make trades or vote  securities  in the Piper Jaffray  Account and
the PaineWebber Account. Each of Michael Yukevich, Jr., Chairman of the Board of
Trustees of the Reporting  Person (the "Board of Trustees")  and a member of the
Finance  Committee,  and Linda K. Miller,  the Business Manager of the Reporting
Person,  is authorized  to direct the trading and voting of the Issuer's  Common
Stock held in the Piper Jaffray  Account in accordance with the decisions of the
Finance Committee. Each of Alan J. Andreini,  Chairman of the Finance Committee,
and John A. Pidgeon,  the Headmaster of the Reporting  Person,  is authorized to
direct  the  trading  and  voting  of the  Issuer's  Common  Stock  held  in the
PaineWebber Account in accordance with the decisions of the Finance Committee.

         From April 1996 to February 22, 1999,  Mr.  Andreini was  authorized by
the Board of Trustees to exercise investment and voting power over the shares of
the Issuer's  Common Stock held in the Piper Jaffray Account and the PaineWebber
Account.  During such  period,  Mr.  Andreini  was  permitted  to exercise  such
authority without approval from the Finance  Committee.  In March 1999, when Mr.
Andreini  requested the  termination of his investment and voting power over the
securities held in the Piper Jaffray Account and the  PaineWebber  Account,  all
investment  and voting power


                                  Page 3 of 47


<PAGE>



over any securities  held in such Accounts  became subject to the prior approval
of the Finance  Committee.  Mr.  Andreini is still an authorized  person for the
PaineWebber Account.

          Mr. Andreini has filed a Schedule 13D and a Schedule 13G under his own
name with respect to the Issuer's Common Stock and he is not a reporting person
hereunder. Mr. Andreini's filings disclose the Reporting Person's ownership of
the Issuer's Common Stock.

         Information with respect to the Reporting Person and the members of the
Finance  Committee  (in  accordance  with  Instruction C to Schedule 13D) is set
forth below.

            EXHIBIT 4 - FORM OF PIPER JAFFRAY PRIME ACCOUNT AGREEMENT

PIPER JAFFRAY                                        PRIME ACCOUNT(TM)
                                                     AGREEMENT

PLEASE READ CAREFULLY.

1. This AGREEMENT  ("AGREEMENT")  sets forth the terms and conditions  governing
the Piper Jaffray PRIME  ACCOUNT(TM)  ("Piper Jaffray Prime Account") offered by
Piper  Jaffray  Inc.  ("Piper  Jaffray"),  for which  you (all such  signatories
hereto,  whether acting in their individual or  representative  capacities,  are
sometimes  referred to hereinafter as "you") are making  application  with Piper
Jaffray.  This Agreement is subject to, and may be modified from time to time by
disclosure in, the prospectuses  pertaining to the money market investment funds
from time to time offered by Piper  Jaffray as a component of the Piper  Jaffray
Prime Account (the "Funds"),  and any supplement or amendment  thereto as of the
time of filing or  effectiveness  thereof  (the  prospectuses,  as so amended or
supplemented, are referred to as the "Prospectuses").

Subject to the foregoing,  it is understood that the Piper Jaffray Prime Account
will operate as follows:

2.  DESCRIPTION OF PIPER JAFFRAY PRIME ACCOUNT
The Piper Jaffray Prime Account is an integrated financial services program that
links together several components:

o    a Piper Jaffray securities account (the "Securities Account") with a credit
     feature;
o    the Funds from time to time offered by Piper Jaffray;
o    a  check-writing privilege provided by PNC Bank, Philadelphia, a subsidiary
     of  PNC  Financial  Corp (PNC Bank,  Philadelphia  and its  affiliates  are
     referred to as "PNC"); and
o    an optional Visa Gold" card  including ATM access,  from PNC. The principal
     attributes  of each  component of the Piper Jaffray Prime Account and their
     relation to one another are described below.

3.  SECURITIES ACCOUNT
The Securities Account has a credit feature.  You may use the Securities Account
to purchase and sell securities,  including options,  for cash or on credit. The
Securities  Account will be governed by the federal  securities  laws, the rules
and  regulations  of the  Securities  and  Exchange  Commission,  the  Board  of
Governors of the Federal  Reserve  System,  the Securities  Investor  Protection
Corporation,  the New York  Stock  Exchange,  Inc.,  other  registered  national
securities  exchanges,  the National Association of Securities Dealers, Inc. and
by this Agreement and the policies of Piper Jaffray.

The amount of available  credit will vary  depending upon the amount of eligible
securities  in your  Piper  Jaffray  Prime  Account  and  applicable  regulatory
requirements,  but is  presently  limited to 50% of the current  market value of
eligible securities in your Piper Jaffray Prime Account.


                                 Page 25 of 47

<PAGE>


When you purchase  securities,  Piper  Jaffray will first apply any cash in your
Piper Jaffray Prime Account on the  settlement  date and then redeem Fund shares
at net asset value to the extent  necessary to pay the amounts due in connection
with such transaction,  including all costs and expenses of the transaction.  If
at the settlement  date, such amounts are sufficient to pay all amounts due, the
trade will be treated as a cash transaction.

If on the settlement  date,  there is not sufficient  cash or net asset value of
Fund shares in your Piper Jaffray Prime Account, Piper Jaffray may extend credit
to you on the terms and conditions set forth in this Agreement. If Piper Jaffray
extends  credit to you,  such amounts will be  automatically  collateralized  by
eligible  securities in your Piper Jaffray Prime Account. If sufficient eligible
securities  are not  available in your Piper  Jaffray  Prime  Account,  you must
deposit additional cash and/or eligible securities into your Piper Jaffray Prime
Account within the allotted time frames required by the laws, rules, regulations
and policies  governing the extension of credit by Piper Jaffray.  If sufficient
cash or eligible  securities  are not  deposited  into the Piper  Jaffray  Prime
Account  within the allotted time frames  prescribed  by  applicable  regulatory
requirements, Piper Jaffray is required to liquidate the trade(s) at market risk
and exposure to you.

A.        PLACING ORDERS, CUSTOMER RESPONSIBILITIES. When you place any order to
          sell securities  that are long in your account,  you will designate it
          as such and hereby authorize Piper Jaffray to mark such order as being
          "long".  Any sell order  which you shall  designate  as being for long
          account  will  be for  securities  then  owned  by  you,  and if  such
          securities are not then  deliverable by Piper Jaffray from any account
          of yours,  you will deliver such  securities as soon as you can do so.
          If you place any order to sell securities that are short your account,
          you will designate it as such and authorize Piper Jaffray to mark such
          order as being  "short".  In case Piper  Jaffray makes a short sale of
          any  securities at your  direction,  or in case you fall to deliver to
          Piper  Jaffray any  securities  which  Piper  Jaffray has sold at your
          direction,  you  authorize  Piper  Jaffray  to borrow  the  securities
          necessary to enable Piper Jaffray to make  delivery to the  purchaser,
          and you agree to be responsible for the cost or loss Piper Jaffray may
          incur,  or the cost of otherwise  obtaining  the  securities  if Piper
          Jaffray is unable to borrow them. No settlement of any account for you
          may be made by you without  all  securities  in which your  account is
          short being received by Piper Jaffray and all securities in which your
          account  is long  being  paid  for in full  and  the  securities  then
          delivered. Piper Jaffray and its correspondents are designated as your
          agents to consummate all such transactions, and are authorized to make
          such advances and expend such moneys as may be required.

B.        CUSTOMER'S  ORDERS  BINDING  UNTIL  NOTICE OF DEATH;  PIPER  JAFFRAY'S
          RIGHTS TO PURCHASE OR SELL.  Any order you give Piper Jaffray shall be
          binding upon you and your personal  representative until Piper Jaffray
          has actual notice of your death.  Your death and notice  thereof shall
          not in any way affect Piper  Jaffray's  rights under this Agreement to
          take any action  which Piper  Jaffray  could have taken if you had not
          died.  Upon your  death or  failure  to  comply  with any part of this
          Agreement  or  whenever  Piper  Jaffray  deems  it  necessary  for its
          protection, Piper Jaffray is authorized (but is not required) to:

          o    Cancel outstanding orders;
          o    Purchase,  sell, assign, receive and deliver  all or any  part of
               the securities held or carried for you; and

                                 Page 26 of 47


<PAGE>


          o    Close  out short sales by  purchase  upon any  exchange  board or
               market or any public or private sale at Piper Jaffray's option.

C.        SECURITIES  PENDING ISSUE. On transactions in securities  when, as and
          if issued,  Piper  Jaffray  is  entitled  to  protection  against  its
          contingent  liability  pending the issue of the securities to the same
          extent as in purchases and sales of securities already issued.

D.         WAIVER OF NOTICE. Piper Jaffray may take these actions without demand
          for credit or notice of purchase or sale, which are expressly  waived.
          No specific  demand or notice  shall  invalidate  this  waiver.  After
          deducting  all costs and  expenses  of any such  purchase  or sale and
          delivery,  Piper  Jaffray is  authorized  to apply the  residue of the
          proceeds  to  the  payment  of  your  liabilities  to  Piper  Jaffray,
          returning the surplus, if any, to you, and you shall remain liable for
          any deficiency. At any such sale at public auction or on any exchange,
          Piper Jaffray may become  purchasers for itself or on behalf of anyone
          else.

4.  CREDIT EXTENSIONS
PLEASE  NOTE - SECTION 4  CONCERNING  CREDIT WILL ONLY APPLY WHEN AND IF YOU ARE
CARRYING A SETTLEMENT  DATE DEBIT  BALANCE IN YOUR PIPER  JAFFRAY  PRIME ACCOUNT
(PIPER JAFFRAY IS LENDING YOU MONEY AGAINST YOUR SECURITIES AS COLLATERAL).

If Piper Jaffray  extends a loan based on the credit feature of your  Securities
Account,  Piper Jaffray will begin to charge interest on the day it extends such
credit to you. As with any credit  extension  by Piper  Jaffray,  you must be in
compliance with all current regulations and New York Stock Exchange  maintenance
requirements.

A.        CUSTOMER OBLIGATION.  You will pay interest on all amounts advanced by
          Piper Jaffray and on other  balances due Piper Jaffray  (including all
          commissions  and such other  charges as Piper  Jaffray  may impose) as
          specified  under the  caption  "Credit  Terms" in this  Agreement.  In
          addition,  you  specifically  agree that Piper  Jaffray may check your
          credit  references  at any time,  and  authorize  anyone to grant that
          information  to Piper  Jaffray.  Piper  Jaffray may at any time demand
          that your account or accounts  immediately  be taken up and paid,  and
          all  amounts  advanced  and other  balances  due,  with  interest  and
          commissions,  shall be due and  payable  on demand.  Unless  demand is
          sooner made,  interest is due and payable monthly or upon the balances
          due  being  paid in full.  You will at all times  maintain  sufficient
          collateral  for said  accounts as from time to time  required by Piper
          Jaffray.

B.        CREDIT  TERMS.  Piper Jaffray  charges in  connection  with any credit
          Piper Jaffray may extend to you are as follows:

You will be charged  interest  on any credit  extended to you for the purpose of
purchasing,  carrying,  trading or selling any  securities.  Such  extensions of
credit include but are not limited to:

          o  prepayment of proceeds of sale prior to settlement;

          o payments on "no good delivery" securities prior to clearance;

          o specific transactions where interest expenses are incurred.


                                 Page 27 of 47


<PAGE>


The annual rate of interest  charged on your average  debit  balance is based on
Piper  Jaffray's  announced  broker  call  rate,  which is  determined  by Piper
Jaffray's cost of borrowing  money from banks.  To Piper  Jaffray's  broker call
rate,  Piper Jaffray will add a maximum 2.5% override.  Piper Jaffray may charge
lower  overrides  depending  upon  factors such as the size of your net balance,
Piper Jaffray's  evaluation of the commission  income generated by your account,
the service required for the account, etc.

Your rate of interest will be changed  without notice in accordance with changes
in your net balance due and changes in Piper Jaffray's cost of borrowing  money.
When your interest  rate is to be increased  for any other  reason,  at least 30
days' prior written notice will be given.

THE METHOD OF COMPUTING INTEREST IS AS FOLLOWS: Interest is accrued daily on all
funds owed to Piper Jaffray (debit  balances).  Free credit  balances  within an
account are used to offset the debit balance each day. Piper Jaffray's  interest
period  runs  from the  16th of the  previous  month to the 15th of the  current
month.  Therefore,  to compute  your  interest,  it will be necessary to use the
prior month's statement as well as the current statement.

Begin with the debit  balance on the 15th of the previous  month.  Starting with
the 16th and each day  through the 15th of the  current  statement,  add to that
debit balance any debits and subtract any credits appearing on your statement to
determine each day's debit  balance.  Free credits within an account are used to
offset the debit  balance each day. The average  debit  balance is determined by
adding the debit balances for each day and dividing by the number of days in the
billing  period.  Multiply  this by the annual rate of interest  and then by the
number of days in the billing period. Then divide by 360.

In order to assist you,  your  monthly  statements  will  contain the  following
information:  annual rate of interest charged to your account, the average daily
debit, and ending debit balance of interest period (15th of the month).

The credit that appears on your  statement due to short sales  (including  short
sales against the box) is offset by a debit of like amount because Piper Jaffray
has to borrow the same  security  in order to  deliver it to the buying  broker.
This  means  that the credit  generated  by any short sale does not reduce  your
debit balance for the purpose of computing  interest until the short position is
covered.

If the security which you sold short (or sold short against the box) appreciates
in  market  price  over the  selling  price,  interest  will be  charged  on the
appreciation of the value.  If the security which you sold short  depreciates in
market  price,  interest  is  correspondingly  reduced  by the  drop  in  value.
Periodically,  and  depending  upon  prevailing  conditions,  this  practice  of
"marking-to-the-market" is performed.

If you have any further  questions about interest  charged to your account,  you
should contact your Piper Jaffray Investment Executive.

C.       LIENS, PLEDGING AND LENDING OF SECURITIES IN ACCOUNT.


                                 Page 28 of 47


<PAGE>


          PLEASE NOTE- IN ACCORDANCE WITH SEC RULE 15C3-3(B),  WE ARE PROHIBITED
          FROM  LENDING  ANY OF  YOUR  SECURITIES  UNLESS  YOU  ARE  CARRYING  A
          SETTLEMENT DATE DEBIT BALANCE  AGAINST YOUR SECURITIES  (PIPER JAFFRAY
          IS LENDING YOU MONEY AGAINST YOUR SECURITIES AS COLLATERAL).

          If you use the credit feature of your Piper Jaffray Prime Account, any
          securities  in any of your  accounts  are  collateral  for  any  debit
          balances  in your  Piper  Jaffray  Prime  Account.  This means that in
          accordance with the terms of this Agreement,  securities in your Piper
          Jaffray Prime Account or other accounts with Piper Jaffray can be sold
          to reduce or to liquidate  entirely  any debit  balances in your Piper
          Jaffray Prime Account.

          If you use the credit  feature of your Piper Jaffray Prime Account and
          if there is a decline in the market value of your securities which are
          the collateral  for your debit balance,  it may be necessary for Piper
          Jaffray to  request  additional  funds or  collateral.  Ordinarily,  a
          request  for  additional  funds or  collateral  will be made  when the
          equity in the account  falls  below 33 percent of the market  value of
          all securities in the account.  (The equity is the excess market value
          of the  securities  in the account over the debit  balance.)  However,
          Piper  Jaffray  retains  the  right  to  require  additional  funds or
          collateral when Piper Jaffray deems it desirable.

          All  securities  held or purchased  by Piper  Jaffray for you shall be
          subject  to a lien for the  payment of all your  liabilities  to Piper
          Jaffray.  Piper Jaffray is authorized  without notice to you, whenever
          Piper Jaffray deems it advisable, to transfer  interchangeably between
          any accounts you have with. Piper Jaffray any or all of the securities
          so held, and without notice to you and without regard to whether Piper
          Jaffray  has in its  possession  or subject to its control at the time
          thereof other securities of the same kind and amount, and in the usual
          course of business, to pledge,  repledge,  hypothecate,  rehypothecate
          (EITHER FOR THE AMOUNT DUE IPER  JAFFRAY  FROM YOU OR FOR A GREATER OR
          LESSER  SUM) and lend the same to itself as brokers or to others  from
          time to time,  separately or commingled  with  securities  carried for
          other customers. Piper Jaffray shall not be required to deliver to you
          the identical  securities deposited or received but only securities of
          the same kind and amount.

5.       THE FUNDS
You authorize Piper Jaffray to invest  automatically  in shares of the Fund from
time  to  time  designated  by you  (the  "Designated  Fund")  any  cash in your
Securities  Account  (that is,  any cash that does not  result  from a loan from
Piper  Jaffray,  and thus,  may be transferred  out of your  Securities  Account
without giving rise to interest charges).  Such automatic  investment of cash in
Designated  Fund  shares will occur  daily on the next  business  day at the net
asset  value  per  share  next  determined.   Although  cash  will  be  invested
automatically  in only the Designated Fund, you may purchase shares in the other
Funds at any time.

Shares of the  Designated  Fund and shares of other  Funds will be  redeemed  at
their net asset value and you authorize automatic redemptions,  as necessary, to
satisfy debit balances resulting from securities  transactions,  from the use of
the  check-writing  privilege and/or the optional Visa Gold(R) card as described
below.  You may also  redeem  shares of the Funds  directly  by  written or oral
request to Piper Jaffray.

Your  Designated  Fund Option will be changed to the First  American Funds Prime
Obligations  Fund-Class Y, if the value of your account  reaches the minimum set
forth in the  current  prospectus.  Your


                                 Page 29 of 47


<PAGE>


account  will not be  affected if your  Designated  Fund is a  tax-exempt  money
market fund.  Piper Jaffray will  evaluate  accounts on the last business day of
each  calendar  year quarter end. We will make the change on the first  business
day of the  calendar  year  quarter  that begins after the value of your account
reaches the minimum.

Orders for the purchase or  redemption  of Fund shares will become  effective as
provided in the Prospectuses.  Ordinarily,  a purchase order will not be entered
until cash in the form of Federal Funds become available to Piper Jaffray. Piper
Jaffray may, however, without charge, advance Federal Funds to the Piper Jaffray
Prime Account on your behalf to enable you to purchase Fund shares and earn Fund
dividends prior to final collection of checks or other instruments  deposited in
your Securities  Account.  You therefore agree that Piper Jaffray may reasonably
withhold access to the redemption proceeds of Fund shares purchased by checks or
other instruments credited to your Piper Jaffray Prime Account.

The Funds will  declare  dividends on each  business  day as earned,  and credit
dividends  monthly  on shares  of the Funds  owned by you.  You  recognize  that
dividends are paid in  additional  Fund shares,  unless  monthly cash payment is
requested.

6.  PIPER JAFFRAY PRIME ACCOUNT FEE
Piper  Jaffray will deduct an annual fee from your Piper  Jaffray  Prime Account
for processing and administrative services. Piper Jaffray will notify you before
any increase in the fee becomes effective.  In addition,  the following fees may
apply depending on the account's transactions and activity:

o        All trades  (purchases and sales) will be charged a $5 transaction fee.
         Some managed  account types are excluded as well as mutual fund trades,
         syndicate  offerings,  annuities,  insurance,  or trades  with a dollar
         value of less than $5.
o        Accounts transferring to other firms are subject to a $50 transfer fee.
o        Foreign  securities  transacted  on a foreign  exchange(ordinary  "ORD"
         shares) will be charged the $ 100 fee at the time of purchase and sale.

Piper  Jaffray  reserves  the  right to  change  its  fees for the  maintenance,
administration  and servicing of a Piper Jaffray  Prime  Account.  Piper Jaffray
will  provide you with prior  notification  of an  increase to the fees  payable
hereunder.

7.  CHECK-WRITING PRIVILEGES (OPTIONAL)
You may exercise a check-writing  privilege  through an account with PNC. In the
case of a  corporate  account,  a maximum of six (6)  authorized  check  signers
designated  by  corporate  resolutions  may exercise a  check-writing  privilege
through an account maintained at PNC. PNC will assess certain charges associated
with such a  privilege.  Checkwriting  privileges  are  subject to an  agreement
between Piper Jaffray and PNC.

You must maintain sufficient  Available Cash in your Securities Account and Fund
shares  ("Combined  Asset  Value") to pay any checks you write and any Visa Gold
card  transactions  made by you or any  additional  authorized  Visa  Gold  card
cardholder.  Payments  for  checks and for Visa Gold card  transactions  will be
satisfied  from the Combined  Asset Value of your Piper Jaffray Prime Account in
the following order: First, from cash in your Securities  Account;  second, from
the


                                 Page 30 of 47

proceeds of redeeming  Designated Fund shares (if any);  third from the proceeds
of redeeming other Fund shares (if any); and fourth, from the loan value of your
loanable securities (if any).

8.  THE VISA GOLD(R)CARD FEATURES (OPTIONAL SERVICES)
APPROVING  THE VISA GOLD  CARD - If you  would  like a Visa Gold Card as part of
your Piper Jaffray Prime Account,  complete the credit card application included
in this package.  PNC, the card issuing bank, must approve your  application for
the credit card before any Visa Gold card services can be linked with your Piper
Jaffray Prime  Account.  If approved,  PNC will issue and service your Visa Gold
card account with a minimum credit line of $5,000.

ADDITIONAL  CARDS - Each  individual  applicant  who  signs  the Visa  Gold card
application  may  apply for and  receive a Visa Gold card for use in  connection
with your Piper Jaffray Prime Account.  You and other  cardholders who are Piper
Jaffray Prime Account  clients may jointly  authorize the issuance of additional
cards.  Additional  cardholders  who are not Piper Jaffray Prime Account clients
are  not  authorized  to buy or  sell  securities  or to use  the  check-writing
privilege associated with the Piper Jaffray Prime Account. The fee for the Piper
Jaffray  Prime Account with the optional Visa Gold card includes the issuance of
up to two cards. There is a charge for the issuance of each additional card.

USING THE VISA  GOLD  CARD - You,  and any  additional  cardholder,  may use the
credit card to charge goods and services wherever the Visa Gold card is accepted
(Visa Gold card  charge  transactions).  You may also  obtain  cash  advances at
participating  financial  institutions or any Plus System(R) location (Visa Gold
card cash advance  transactions).  The amount of purchases and cash advances may
not exceed  the  available  credit on your Visa Gold  card.  You agree to accept
financial  responsibility  with  respect  to all Visa Gold card  charge and cash
advance   transactions   effected  by  any  cardholder,   including   additional
cardholders, in accordance with the Credit Card Agreement.

VISA GOLD CARD  TRANSACTIONS  - PNC will send you a statement  showing your Visa
Gold card  transactions  and/or other  activity for the billing  period in which
such transactions or other activity occurred.

You authorize  Piper Jaffray to  automatically  transfer funds from the Combined
Asset  Value of your Piper  Jaffray  Prime  Account  to pay  amounts to PNC when
requested  by  PNC.  The  amount  of  any  cash  advance  transactions  will  be
transferred  from  your  Piper  Jaffray  Prime  Account  on the day such item is
presented for payment.  Charge  transactions from the most recent billing period
will be  transferred  from your Piper  Jaffray Prime Account once a month on the
payment date  indicated  on the  statement  issued you by PNC. If your  Combined
Asset Value will not pay the entire amount of newly-billed Visa Gold card charge
transactions  on the payment date,  you will have 10 days to transfer  assets to
the Piper Jaffray Prime Account.

If you do not make funds  available for payment when due,  finance  charges will
accrue as provided in the Credit Card Agreement. If payment is made on or before
the applicable  payment due date as provided in the Credit Card  Agreement,  and
there  was no  previous  balance,  then no  finance  charges  will be  assessed.
Whenever  finance  charges are assessed,  the Annual  Percentage Rate will be as
stated in the Credit Card Agreement.

For additional  information regarding your Visa Gold card account,  refer to the
Credit Card Agreement which will accompany your Visa Gold card(s).

TERMINATION  OF THE VISA  GOLD  CARD  FEATURE  - Any  cardholder  who is a Piper
Jaffray  Prime  Account  client  may  terminate  the Visa Gold card  feature  by
notifying  Piper  Jaffray in  writing.  In any such event,  we request  that you
return  all Visa Gold  cards,  cut in half,  to your  Piper  Jaffray  Investment
Executive. Such termination does not relieve you of responsibility for charge or
cash advance  transactions made using the Visa Gold card, nor, will it terminate
your Piper Jaffray Prime Account.  PNC may terminate your Visa Gold card feature
in accordance  with the terms of the Credit Card Agreement but such  termination
need not terminate your Piper Jaffray Prime Account.

REVOKING  ADDITIONAL  CARDHOLDERS'  PRIVILEGES - You may revoke the authority of
any additional  cardholders who are not Piper Jaffray Prime Account clients.  To
revoke the  authority of any  additional  cardholders  notify  Piper  Jaffray in
writing.  In any such event, we request that you return all Visa Gold cards, cut
in half, to your Piper Jaffray Investment  Executive.  You remain liable for any
losses incurred either before we receive your written notice of revocation or as
a result of any use of the Visa Gold card that occurs before we receive  written
notice, in accordance with the Credit Card Agreement.

You agree not to use under any  circumstances  either directly or indirectly the
Visa  Gold(R)  card to  purchase,  carry or  otherwise  trade in any  securities
(including  shares of the Funds) and that,  if you make any such use of the Visa
Gold card,  Piper  Jaffray may  immediately  terminate  your Piper Jaffray Prime
Account,  redeem your Fund shares, sell securities in your Securities Account to
satisfy all outstanding  loans, and cause PNC to revoke the Visa Gold cards, and
terminate the check-writing privilege.

9.  CHECKS AND VISA GOLD(R) CARD CASH ADVANCE TRANSACTIONS
Piper Jaffray will debit your account immediately  whenever a check is presented
for payment on your behalf,  or, when Piper  Jaffray is notified  that you or an
additional  authorized  Visa Gold card  cardholder has effected a Visa Gold card
cash advance.  You authorize Piper Jaffray to automatically  transfer funds from
your Piper  Jaffray  Prime Account to PNC to cover checks or Visa Gold card cash
advances.

10.  PERIODIC REPORTS
Each month Piper  Jaffray will send a statement  of account (or  quarterly if no
activity) to you at the mailing address  furnished by you to Piper Jaffray.  The
statement  will detail,  among other  things,  loan  interest  charges,  if any,
dividends received on securities held in your Securities  Account,  Visa Gold(R)
card  transactions,  and  checks  drawn on PNC.  Once a year,  the amount of the
annual fee that Piper  Jaffray  charges for the Piper Jaffray Prime Account will
be indicated on the monthly statement, and you authorize Piper Jaffray to deduct
that annual fee from your Piper Jaffray Prime  Account.  You  understand  that a
copy of your monthly  statement  will be sent to your Piper  Jaffray  Investment
statement will be sent to your Piper Jaffray Investment Executive. Confirmations
detailing  specific purchases and redemptions of Fund shares will not be sent to
you. PNC will forward canceled checks to you.

          EXHIBIT 5 - FORM OF PIPER JAFFRAY PAT PLUS ACCOUNT AGREEMENT

USBANCORP                PAT PLUS ACCOUNT(TM)
PIPER JAFFRAY(R)         AGREEMENT

PLEASE READ CAREFULLY.

This agreement  ("Agreement") sets forth the terms and conditions  governing the
U.S.  Bancorp Piper Jaffray PAT Plus Account TM ("PAT PLUS ACCOUNT")  offered by
U.S. Bancorp Piper Jaffray Inc. ("U.S.  Bancorp Piper  Jaffray"),  for which you
(all  such   signatories   hereto,   whether  acting  in  their   individual  or
representative  capacities,  are  sometimes  referred  to as "you")  are  making
application with U.S.  Bancorp Piper Jaffray.  This Agreement is subject to, and
may be modified from time to time by disclosure in, the prospectuses  pertaining
to the money market  investment  funds from time to time offered by U.S. Bancorp
Piper  Jaffray as a component  of the PAT Plus Account  (the  "Funds"),  and any
supplement  or  amendment  thereto  as of the time of  filing  or  effectiveness
thereof (the prospectuses, as so amended or supplemented, are referred to as the
"Prospectuses").

Subject  to the  foregoing,  it is  understood  that the PAT Plus  Account  will
operate as follows:

1.   DESCRIPTION OF PAT PLUS ACCOUNT.

The PAT Plus  Account is an  integrated  financial  services  program that links
together several components:

(1)   a U.S. Bancorp Piper Jaffray securities account (the "Securities Account")
      with a ready purchase credit feature;

(2)   the Funds from time to time offered by U.S. Bancorp Piper Jaffray; and

(3)   cash access check-writing privilege provided by Provident National Bank
      (IF REQUESTED), A subsidiary of PNC Financial Corp (PROVIDENT NATIONAL
      BANK AND ITS AFFILIATES ARE REFERRED TO AS "PROVIDENT" ) or such other
      bank as U.S. Bancorp Piper Jaffray from time to time may select.

The  principal  attributes  of each  component of the PAT Plus Account and their
relation to one another are described below.

2.   SECURITIES ACCOUNT.
The  Securities  Account  is linked to a credit  account  with a ready  purchase
credit  feature.  You  may use the  Securities  Account  to  purchase  and  sell
securities,  including  options,  for cash or on credit.  If the ready  purchase
credit  feature is used,  the  Securities  Account  will  operate  like a credit
account. The Securities Account will be governed by the federal securities laws,
the rules and regulations of the Securities and Exchange  Commission,  the Board
of Governors of the Federal Reserve System, the Securities  Investor  Protection
Corporation,  the New York  Stock  Exchange,  Inc.,  other  registered  national
securities exchanges,  the National Association of Securities Dealers', Inc. and
by this Agreement and the policies of U.S. Bancorp Piper Jaffray.

The amount of  available  ready  purchase  credit will vary  depending  upon the
amount of eligible securities in your PAT Plus Account and applicable regulatory
requirements,  but is  presently  limited to 50% of the current  market value of
eligible securities in your PAT Plus Account.


                                  Page 38 of 47


<PAGE>


When you purchase  securities,  U.S.  Bancorp Piper Jaffray will first apply any
cash in your PAT Plus Account on the settlement date and then redeem Fund shares
at net asset value to the extent  necessary to pay the amounts due in connection
with such transaction,  including all costs and expenses of the transaction.  If
at the settlement  date, such amounts are sufficient to pay all amounts due, the
trade will be treated as a cash transaction.

If on the settlement  date,  there is not sufficient  cash or net asset value of
Fund shares in your PAT Plus  Account,  U.S.  Bancorp  Piper  Jaffray may extend
credit to you on the terms and conditions set forth in this  Agreement.  If U.S.
Bancorp Piper Jaffray extends credit to you, such amounts will be  automatically
collateralized  by eligible  securities in your PAT Plus Account.  If sufficient
eligible  securities  are not  available  in your  PAT Plus  Account  , you must
deposit  additional cash and/or  eligible  securities into your PAT Plus Account
within the allotted  timeframes  required by the laws,  rules,  regulations  and
policies  governing the extension of credit by U.S.  Bancorp Piper  Jaffray.  If
sufficient  cash or  eligible  securities  are not  deposited  into the PAT Plus
Account  within the allotted  timeframes  prescribed  by  applicable  regulatory
requirements,  U.S.  Bancorp Piper Jaffray is required to liquidate the trade(s)
at market risk and exposure to you.

a.    PLACING ORDERS, CLIENT RESPONSIBILITIES.  When you place any order to sell
      securities  that are long in your account,  you will  designate it as such
      and hereby account,  you will authorize U.S. Bancorp Piper Jaffray to mark
      such order as being  "long".  Any sell order which you shall  designate as
      being for long  account will be for  securities  then owned by you, and if
      such  securities are not then  deliverable  by U.S.  Bancorp Piper Jaffray
      from any account of yours, you will deliver such securities as soon as you
      can do so. If you place any order to sell  securities  that are short your
      account,  you will designate it as such and authorize  U.S.  Bancorp Piper
      Jaffray to mark such order as being  "short".  In case U.S.  Bancorp Piper
      Jaffray makes a short sale of any securities at your direction, or in case
      you fail to deliver to U.S.  Bancorp  Piper Jaffray any  securities  which
      U.S. Bancorp Piper Jaffray has sold at your direction,  you authorize U.S.
      Bancorp  Piper Jaffray to borrow the  securities  necessary to enable U.S.
      Bancorp Piper Jaffray to make delivery to the purchaser,  and you agree to
      be responsible for the cost or loss U.S.  Bancorp Piper Jaffray may incur,
      or the cost of otherwise  obtaining the  securities if U.S.  Bancorp Piper
      Jaffray is unable to borrow them. No settlement of any account for you may
      be made by you without all securities in which your account is short being
      received by U.S.  Bancorp Piper  Jaffray and all  securities in which your
      account is long being paid for in full and the securities  then delivered.
      U.S. Bancorp Piper Jaffray and its  correspondents  are designated as your
      agents to consummate  all such  transactions,  and are  authorized to make
      such advances and expend such moneys as may be required.

b.    CLIENT'S  ORDERS  BINDING  UNTIL  NOTICE  OF  DEATH;  U.S.  BANCORP  PIPER
      JAFFRAY'S  RIGHTS TO  PURCHASE  OR SELL.  Any order you give U.S.  Bancorp
      Piper Jaffray  shall be binding upon you and your personal  representative
      until U.S.  Bancorp Piper  Jaffray has actual  notice of your death.  Your
      death and notice  thereof  shall not in any way affect U.S.  Bancorp Piper

c.    SECURITIES  PENDING ISSUE. On  transactions in securities  when, as and if
      issued,  U.S. Bancorp Piper Jaffray is entitled to protection  against its
      contingent  liability  pending  the  issue of the  securities  to the same
      extent as in purchases and sales of securities already issued.

d.    WAIVER OF NOTICE.  U.S.  Bancorp  Piper  Jaffray  may take  these  actions
      without  demand  for  credit  or  notice of  purchase  or sale,  which are
      expressly  waived.  No specific  demand or notice  shall  invalidate  this
      waiver.  After  deducting  all costs and expenses of any such  purchase or
      sale and delivery,  U.S.  Bancorp Piper Jaffray is authorized to apply the
      residue of the proceeds to the payment of your liabilities to U.S. Bancorp
      Piper Jaffray, returning the surplus, if any, to you, and you shall remain

4.   CREDIT EXTENSIONS

PLEASE  NOTE - SECTION 3  CONCERNING  CREDIT WILL ONLY APPLY WHEN AND IF YOU ARE
CARRYING A SETTLEMENT DATE DEBIT BALANCE IN YOUR PAT PLUS ACCOUNT (U.S.  BANCORP
PIPER JAFFRAY IS LENDING YOU MONEY AGAINST YOUR SECURITIES AS COLLATERAL).

If U.S.  Bancorp Piper Jaffray extends a loan based on the ready purchase credit
feature of your  Securities  Account,  U.S.  Bancorp Piper Jaffray will begin to
charge  interest  on the day it extends  such  credit to you. As with any credit
extension by U.S.  Bancorp Piper  Jaffray,  you must be in  compliance  with all
current regulations and New York Stock Exchange maintenance requirements.

a.    CLIENT  OBLIGATION.  You will pay interest on all amounts advanced by U.S.
      Bancorp Piper Jaffray and on other balances due U.S. Bancorp Piper Jaffray
      (including all  commissions  and such other charges as U.S.  Bancorp Piper
      Jaffray may impose) as specified  under the caption "Credit Terms" in this
      Agreement.  In addition,  you  specifically  agree that U.S. Bancorp Piper
      Jaffray may check your credit references at any time, and authorize anyone
      to grant that  information  to U.S.  Bancorp Piper Jaffray.  U.S.  Bancorp
      Piper  Jaffray  may at any time  demand  that  your  account  or  accounts
      immediately  be taken up and  paid,  and all  amounts  advanced  and other
      balances due, with interest and  commissions,  shall be due and payable on
      demand.  Unless demand is sooner made, interest is due and payable monthly
      or upon  the  balances  due  being  paid in full.  You  will at all  times
      maintain  sufficient  collateral  for said  accounts  as from time to time
      required by U.S. Bancorp Piper Jaffray.

b.    CREDIT TERMS.  U.S.  Bancorp Piper Jaffray  charges in connection with any
      credit U.S. Bancorp Piper Jaffray may extend to you are as follows:


                                  Page 40 of 47


<PAGE>


You will be charged  interest  on any credit  extended to you for the purpose of
purchasing,  carrying,  trading or selling any  securities.  Such  extensions of
credit include but are not limited to:

o     prepayment of proceeds of sale prior to settlement;
o     payments on "no good delivery" securities prior to clearance;  specific
o     transactions where interest expenses are incurred.

The annual rate of interest  charged on your average  debit  balance is based on
U.S. Bancorp Piper Jaffray's  announced broker call rate, which is determined by
U.S. Bancorp Piper Jaffray's cost of borrowing money from banks. To U.S. Bancorp
Piper Jaffray's  broker call rate, U.S. Bancorp Piper Jaffray will add a maximum
2.5% override.  U.S. Bancorp Piper Jaffray may charge lower overrides  depending
upon factors such as the size of your net balance,  U.S. Bancorp Piper Jaffray's
evaluation  of the  commission  income  generated by your  account,  the service
required for the account, etc.

Your rate of interest will be changed  without notice in accordance with changes
in your net balance  due and changes in U.S.  Bancorp  Piper  Jaffray's  cost of
borrowing  money.  When  your  interest  rate is to be  increased  for any other
reason, at least 30 days' prior written notice will be given.

THE METHOD OF COMPUTING INTEREST IS AS FOLLOWS: Interest is accrued daily on all
funds owed to U.S. Bancorp Piper Jaffray (debit balances).  Free credit balances
within an account are used to offset the debit  balance each U.S.  Bancorp Piper
Jaffray's  interest  period runs from the 16th of the previous month to the 15th
of the current month.  Therefore, to compute your interest, it will be necessary
to use the prior month's statement as well as the current statement.

Begin with the debit  balance on the 15th of the previous  month.  Starting with
the 16th and each day  through the 15th of the  current  statement,  add to that
debit balance any debits and subtract any credits appearing on your statement to
determine each day's debit  balance.  Free credits within an account are used to
offset the debit  balance each day. The average  debit  balance is determined by
adding the debit balances for each day and dividing by the number of days in the
billing  period.  Multiply  this by the annual rate of interest  and then by the
number of days in the billing period. Then divide by 360.

In order to assist  you your  monthly  statements  will  contain  the  following
information:  annual rate of interest charged to your account, the average daily
debit, and ending debit balance of interest period (lst of the month).

The credit that appears on your  statement due to short sales  (including  short
sales against the box) is offset by a debit of like amount because U.S.  Bancorp
Piper  Jaffray  has to borrow  the same  security  in order to deliver it to the
buying broker.  This means that the credit  generated by any short sale does not
reduce your debit balance for the purpose of computing  interest until the short
position is covered.

If the security which you sold short (or sold short against the box) appreciates
in  market  price  over the  selling  price,  interest  will be  charged  on the
appreciation of the value.  If the security which you sold short  depreciates in
market  price,  interest  is  correspondingly  reduced  by the  drop  in  value.
Periodically,  and  depending  upon  prevailing  conditions,  this  practice  of
"marking-to-the-market" is performed.

If you have any further  questions about interest  charged to your account,  you
should contact your U.S. Bancorp Piper Jaffray Investment Executive.

C.       LIENS, PLEDGING AND LENDING OF SECURITIES IN ACCOUNT.


                                 Page 41 of 47


<PAGE>


      PLEASE NOTE -- IN ACCORDANCE  WITH SEC RULE  I5C3-3(B),  WE ARE PROHIBITED
      FROM LENDING ANY OF YOUR  SECURITIES  UNLESS YOU ARE CARRYING A SETTLEMENT
      DATE DEBIT BALANCE AGAINST YOUR SECURITIES (U.S.  BANCORP PIPER JAFFRAY IS
      LENDING YOU MONEY AGAINST YOUR SECURITIES AS COLLATERAL).

      If you use the ready purchase credit feature of your PAT Plus Account, any
      securities in any of your accounts are  collateral  for any debit balances
      in your PAT Plus Account.  This means that in accordance with the terms of
      this Agreement, securities in your PAT Plus Account or other accounts with
      U.S. Bancorp Piper Jaffray can be sold to reduce or to liquidate  entirely
      any debit balances in your PAT Plus Account.

      If you use the ready purchase  credit feature of your PAT Plus Account and
      if there is a decline in the market value of your securities which are the
      collateral  for your debit balance,  it may be necessary for U.S.  Bancorp
      Piper Jaffray to request  additional  funds or collateral.  Ordinarily,  a
      request for additional funds or collateral will be made when the equity in
      the account  falls below 33 percent of the market value of all  securities
      in the account.  (The equity is the excess market value of the  securities
      in the  account  over the debit  balance.)  However,  U.S.  Bancorp  Piper
      Jaffray retains the right to require  additional  funds or collateral when
      U.S. Bancorp Piper Jaffray deems it desirable.

      All  securities  held or purchased by U.S.  Bancorp  Piper Jaffray for you
      shall be subject to a lien for the payment of all your liabilities to U.S.
      Bancorp Piper Jaffray.  U.S.  Bancorp Piper Jaffray is authorized  without
      notice to you, whenever U.S. Bancorp Piper Jaffray deems it advisable,  to
      transfer  interchangeably  between any accounts you have with U.S. Bancorp
      Piper Jaffray any or all of the  securities so held, and without notice to
      you and without  regard to whether U.S.  Bancorp  Piper Jaffray has in its
      possession or subject to its control at the time thereof other  securities
      of the same kind and  amount,  and in the usual  course  of  business,  to
      pledge,  repledge,  hypothecate,  rehypothecate (EITHER FOR THE AMOUNT DUE
      U.S.  BANCORP  PIPER  JAFFRAY from you or FOR A GREATER OR LESSER SUM) and
      lend the  same to  itself  as  brokers  or to  others  from  time to time,
      separately or commingled with securities  carried for other clients.  U.S.
      Bancorp  Piper  Jaffray  shall  not be  required  to  deliver  to you  the
      identical securities deposited or received but only securities of the same
      kind and amount.

5.   THE FUNDS.
You authorize U.S.  Bancorp Piper Jaffray to invest  automatically  in shares of
the Fund from time to time designated by you (the "Designated Fund") any cash in
your Securities Account (that is, any cash that does not result from a loan from
U.S. Bancorp Piper Jaffray, and, thus, may be transferred out of your Securities
Account without giving rise to interest  charges).  Free credit cash balances in
your  Securities  Account (as determined in accordance  with U.S.  Bancorp Piper
Jaffray's  normal   procedures)  of  $100  or  more  (subject  to  change)  will
automatically be invested in shares of the Fund at their current net asset value
at least once a week.  Although cash'll be invested  automatically  in only the
Designated Fund, you may purchase shares in the other Funds at any time.

Your  Designated  Fund  Option  will be changed to First  American  Funds  Prime
Obligations Fund - Class Y, if the value of your account reaches the minimum set
forth in the  current  prospectus.  Your  account  will not be  affected if your
Designated  Fund is a tax exempt money market fund.  U.S.  Bancorp Piper Jaffray
will  evaluate  accounts on the last  business day of each calendar year quarter
end.  We will make the change on the first  business  day of the  calendar  year
quarter that begins after the value of your account reaches the minimum.

Shares of the  Designated  Fund and shares of other  Funds will be  redeemed  at
their net asset value and you authorize automatic redemptions,  as necessary, to
satisfy debit balances resulting from securities transactions or from use of the
cash access  check-writing  privilege,  as described  below. You may also redeem
shares of the Funds directly by  written or oral  request  to U.S. Bancorp Piper
Jaffray.



                                 Page 42 of 47


<PAGE>


Orders for the purchase or  redemption  of Fund shares will become  effective as
provided in the Prospectuses.  Ordinarily,  a purchase order will not be entered
until cash in the form of Federal Funds become  available to U.S.  Bancorp Piper
Jaffray.  U.S.  Bancorp  Piper Jaffray may,  however,  without  charge,  advance
Federal  Funds to the PAT Plus  Account on your behalf to enable you to purchase
Fund shares and earn Fund dividends prior to final collection of checks or other
instruments  deposited in your Securities Account. You therefore agree that U.S.
Bancorp Piper Jaffray may reasonably  withhold access to the redemption proceeds
of Fund shares  purchased  by checks or other  instruments  credited to your PAT
Plus Account.

The Funds will  declare  dividends on each  business  day as earned,  and credit
dividends  monthly  on shares  of the Funds  owned by you.  You  recognize  that
dividends are paid in  additional  Fund shares,  unless  monthly cash payment is
requested.

6.   CHECK-WRITING PRIVILEGES.
If you have requested  cash access  check-writing  privileges,  upon approval of
your  application  by  Provident,  you may exercise a cash access  check-writing
privilege  through an account with  Provident.  Provident  will furnish  initial
checks  to you.  In the  case  of a  corporate  account,  a  maximum  of six (6)
authorized check signers designated by corporate resolutions may exercise a cash
access checkwriting privilege through an account maintained at Provident.

You must maintain sufficient  Available Cash in your Securities Account and Fund
shares ("Combined Asset Value") to pay any checks you write. Payments for checks
will be satisfied  from the Combined Asset Value of your PAT Plus Account in the
following order: First, from cash in your Securities  Account;  second, from the
proceeds  of  redeeming  Designated  Fund shares (if any);  and third,  from the
proceeds of redeeming  other Fund shares (if any).  Should these assets prove to
be insufficient, U.S. Bancorp Piper Jaffray will be required to return the check
as nonsufficient funds.

7.   PERIODIC REPORTS.
Each month U.S.  Bancorp  Piper  Jaffray will send a statement of account (or
quarterly if no activity) to you at the mailing address furnished by you to U.S.
Bancorp Piper Jaffray.

The  statement  will  detail,  among  other  things,  reports  of  execution  of
transactions and statements of accounts as required,  account interest  charges,
if any,  dividends received on securities held in your Securities  Account,  and
checks drawn on Provident.  Reports of the execution of orders ("Confirmations")
and  statements  of your  accounts  ("Statements")  shall be  conclusive  if not
objected to in writing within a reasonable  time. Once a year, the amount of the
annual fee, if any, that U.S.  Bancorp  Piper  Jaffray  charges for the PAT Plus
Account will be  indicated  on the monthly  statement,  and you  authorize  U.S.
Bancorp Piper Jaffray to deduct that annual fee from your PAT Plus Account.  You
understand  that a copy  of your  monthly  statement  will be sent to your  U.S.
Bancorp Piper Jaffray  Investment  Executive.  Confirmation  detailing  specific
purchases and redemptions of Fund shares will not be sent to you. Provident will
forward canceled checks to you.

8.   CLIENT REPRESENTATIONS.
Until  advised by you of a change of address,  U.S.  Bancorp Piper Jaffray shall
regard as accurate the address  provided when you opened your account.  All mail
sent by U.S. Bancorp Piper Jaffray to your address shall constitute  delivery to
