                     $500,000 Needed to Break Escrow     
                                ______________

    
     This is an initial public offering of units of limited partnership interest
in Portfolio Boost III, L.P. The initial purchase price is $1,000 per unit. 
The first $500,000 from the sale of units will be placed in an escrow account 
at First American Bank, Fort Dodge, Iowa. If $500,000 is collected before 
October 28, 1999, the escrow account will be closed and the funds in the 
account will be released to PB III for its use. If $500,000 is not collected
before October 28, 1999, this offering will be terminated, and all of the funds
in the escrow account will be returned to the subscribers, along with any
interest earned on the funds.    
    
     PB III will seek long term capital appreciation through trading in domestic
and foreign futures contracts in certain currencies.     

    
     A minimum investment of $5,000 is required for first time investors.

After PB III starts trading, the purchase price for units will be the net asset
value per unit.  No underwriting commissions are payable by PB III, but PB III
will pay filing fees, legal and accounting fees, printing costs and other
expenses.  Those expenses are estimated to be $193,660.  The underwriter will
receive fees from the general partner of PB III.     

    
     The units are speculative, high risk securities.  Before you decide to
invest, read this entire prospectus and carefully consider "Principal Risk
Factors" beginning on page 7.  The risks of this investment include that:     

    
     *    Futures trading is highly speculative and volatile
     *    You could lose all or substantially all of your investment in PB III
     *    PB III is subject to conflicts of interest
     *    The success of PB III's trading will depend entirely on certain
          software
     *    The software has been developed with the benefit of hindsight and is
          untested in actual trading
     *    PB III's trading will not be diversified, and will be limited to only
          certain currencies
     *    There is no public or secondary market for the units, and there are
          conditions and restrictions on assignments of units and on
          liquidations of units by PB III      
    
     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved these securities or determined if this
prospectus is truthful or complete.  Any representation to the contrary is a
criminal offense.

     The Commodity Futures Trading Commission has not passed upon the merits of
participating in this pool nor has the Commodity Futures Trading Commission
passed on the adequacy or accuracy of this prospectus.

                           Risk Disclosure Statement

     You should carefully consider whether your financial condition permits you
to participate in a commodity pool.  In so doing, you should be aware that
futures and options trading can quickly lead to large losses as well as gains.
Such trading losses can sharply reduce the net asset value of the pool and
consequently the value of your interest in the pool.  In addition, restrictions
on redemptions may affect your ability to withdraw your participation in the
pool.

    
     Further, commodity pools may be subject to substantial charges for
management, and advisory and brokerage fees.  It may be necessary for those
pools that are subject to these charges to make substantial trading profits to
avoid depletion or exhaustion of their assets.  This prospectus contains a
complete description of each expense to be charged this pool, beginning at page
35, and a statement of the percentage return necessary to break even, that is,
to recover the amount of your initial investment, at page 39.     

    
     This brief statement cannot disclose all the risks and other factors
necessary to evaluate your participation in this commodity pool.  Therefore,
before you decide to participate in this commodity pool, you should carefully
study this prospectus, including a description of the principal risk factors of
this investment, beginning at page 7.     
   
     You should also be aware that this commodity pool may trade foreign futures
or options contracts.  Transactions on markets located outside the United
States, including markets formally linked to a United States market, may be
subject to regulations which offer different or diminished protection to the
pool and its participants.  Further, United States regulatory authorities may be
unable to compel the enforcement of the rules of regulatory authorities or
markets in non-United States jurisdictions where transactions for the pool may
be effected.

                            -----------------------
    
     The following is a summary of this offering and of PB III .  This summary
is materially complete, but this prospectus contains additional information.

offering and PB III and about any agreement or document discussed in this
prospectus.

sale of units and from the retention of any profits generated from PB III's
trading.

partner.

units will be the net asset value per unit as of the opening of trading on that
day. This offering will be terminated if 500 units are not sold before October
28, 1999. If that happens, all subscriptions will be returned to the subscribers
within 10 business days of October 28, 1999.

Because Quiet Systems is PB III's Only Trading Advisor.  Quiet Systems
- ------------------------------------------------------
Limited will make all of the trading decisions for PB III, so PB III will be
relying solely upon Quiet Systems Limited for establishing a successful trading
program.  The general partner and the limited partners will not receive any
advance notice of PB III's trades.     

    
     It is unlikely that PB III will ever retain any other trading advisors.  PB
III therefore will not have the benefit of diversification in trading methods
that the use of multiple trading advisors may provide.     

    
     PB III May Lose Quiet Systems Services At Any Time. Quiet Systems Limited
     --------------------------------------------------
may terminate or become unable to continue advising PB III. The general partner
may also decide it is in the best interests of PB III to terminate PB III's
relationship with Quiet Systems Limited if Quiet Systems Limited's trading is
not profitable over the long term. No assurance can be given that a substitute
trading advisor will perform as well as Quiet Systems Limited or can be retained
on the same terms as currently in effect with Quiet Systems Limited.    
    
     Quiet Systems Limited relies upon a key person for updating and maintaining
the software it uses in its trading program.  If that person terminates or
becomes unable (through death, disability, etc.) to continue to provide services
to Quiet Systems      

                                       7
<PAGE>
 
    
Limited, the trading program could be adversely affected in a material way.
Quiet Systems Limited may be forced to terminate its services to PB III if it
loses any of its key persons.     

    
      

    
     

    
     

    
     Quiet Systems May Have Difficulties With the Software That Determines the
     -------------------------------------------------------------------------
Trades in the Trading Program. Quiet Systems Limited depends upon certain
- ------------------------------
software for the operation of its trading program. There is no guarantee that
the operation of the software will be uninterrupted or error-free or that the
trading signals generated by the software will generate profits. There also is
no guarantee that the software will continue to be available to Quiet Systems
Limited or that the software can be updated as necessary to properly respond to
changes in the market place and trading conditions. Quiet Systems Limited's use
of the software is also subject to various other matters beyond its control,
like computer viruses, communication line failure, power failure, or equipment
malfunction and failure. Any difficulties or problems with the software will
adversely affect PB III's trading, and may lead to PB III either temporarily or
permanently ceasing trading.    
    
     Quiet Systems Has No Experience or Operating History.  Quiet Systems
     ----------------------------------------------------                
Limited had not directed the trading of any accounts and had no performance
history as of the date of this Prospectus.

     Quiet Systems May Change its Trading Methods, Which Could Result in a 
     ---------------------------------------------------------------------
Material Change in PB III's Trading Approach.  Quiet Systems Limited
- --------------------------------------------                        
may change any of its trading program without notifying the general partner or
the limited partners.  Any changes by Quiet Systems Limited could materially
change the trading approach of PB III.     

    
     Quiet Systems Rate of Return May Be Adversely Affected as the Assets Traded
     ---------------------------------------------------------------------------
by Quiet Systems Increase. A considerable number of analysts believe that a
- --------------------------
trading advisor's rate of return tends to decrease as the amount of funds under
management increases. Quiet Systems Limited contemplates managing a substantial
amount of funds, and there is no assurance that the trading program and PB III
will not be adversely affected by Quiet Systems Limited's management of
additional funds.    

    
     Changes in Trading Advisors by the General Partner May Materially Change
     ------------------------------------------------------------------------
PB III's Trading Approach and the Fees Paid by PB III.  The general partner may
- -----------------------------------------------------                      
retain new or additional trading advisors without the consent of the limited
partners.  Any change in trading advisors could result in a substantial change
in the overall emphasis and diversity of PB III's trading.  The compensation of
any new or additional trading advisors may also be different from that paid to
Quiet Systems Limited.     

    
     If PB III ever retains more than one trading advisor, there still is no
assurance that this change will result in any diversification of the assets of
or the trading methods used by PB III.  It is also possible in this circumstance
that management fees or incentive fees could be payable to one or more of the
advisors during a period in which PB III's net asset value per unit actually
declines due to losses incurred by the other trading advisors.  The use of more
than one trading advisor could also result in PB III holding opposite positions
in the same contracts at the same time.

Risks Relating to Trading and Markets:
- ------------------------------------- 

    
     Futures Prices Are Very Difficult to Predict Because They Are Speculative 
     -------------------------------------------------------------------------
and Volatile. Price movements of futures contracts are highly volatile and are
- -------------
influenced by many factors. Some of those factors are:    

    
     *    changing supply and demand relationships;
     *    weather and other environmental conditions;
     *    acts of God;
     *    agricultural, fiscal, monetary and exchange control programs and
          policies of governments;     
     *    national and international political and economic events and policies;
     *    changes in rates of inflation; and
     *    the general emotions and psychology of the marketplace, which at times
          can be totally unrelated to other more tangible factors.     


                                       10
<PAGE>
 
    
The currency markets which are traded in Quiet Systems Limited's trading program
are in general highly interest rate sensitive. Governments often intervene in
the currency markets with the specific intention of devaluing or revaluing their
currency or influencing exchange or interest rates.    
    
     Year 2000 compliance issues may also adversely affect the markets.     

     None of these factors can be controlled by Quiet Systems Limited.

    
     Even if current and correct information as to substantially all factors is
known or thought to be known, prices still will not always react as predicted.
Trading decisions will be incorrect in many instances, and PB III will enter
into positions which will result in substantial losses.  For example, you should
note that Corn Belt Commodities Round Trip Limited Partnership, another Iowa
limited partnership for which PB III's general partner serves as the general
partner, has failed to generate any profits since 1995.     

    
     The volatility of the futures markets is one reason that an investment in
units should be viewed as a long term investment.     

    
     Year 2000 Risks May Adversely Affect the Futures Markets.  A substantial 
     -------------------------------------------------------- 
amount of public discussion is being devoted to considering and addressing the
ability of businesses and of the various trading markets to cause their
computers, software and related systems to be able to recognize and perform date
sensitive functions both prior to and after December 31, 1999.    
    
     It is possible that some of the futures exchanges or other trading markets
will not achieve Year 2000 compliance before January 1, 2000.  If that occurs,
it would materially and adversely affect futures prices and the ability of the
exchanges and other trading markets to properly function.     

    
     It is likely that not all businesses will timely achieve Year 2000
compliance.  The failure of a substantial number of businesses or business
sectors to achieve Year 2000 compliance could also adversely affect futures
prices.     

                                       11
<PAGE>
 
    
     The general emotions and psychology of the marketplace regarding concerns
for Year 2000 issues could also in itself adversely affect futures prices.     

    
     The computer systems and software of Quiet Systems Limited are Year 2000
compliant.  The computer systems and software of the general partner and of
Frischmeyer Trading Corporation are also Year 2000 compliant.  The general
partner has been advised that the computer systems and software of First Options
of Chicago, Inc. will be Year 2000 compliant by the close of 1998 or January of
1999, but there is no guarantee that First Options of Chicago, Inc. will be Year
2000 compliant prior to January 1, 2000.  There is also no guarantee that the
various exchanges and other trading markets will be Year 2000 compliant by
January 1, 2000.  All United States futures exchanges will, however, be
monitored by the Commodity Futures Trading Commission for their Year 2000
preparedness, and the major foreign futures exchanges are also expected to be
subject to market-wide testing of their Year 2000 compliance during 1999.     

    
     Failure to achieve Year 2000 compliance by First Options of Chicago, Inc.,
any exchange or other trading market or any other third party with whom PB III
may have a material relationship could result in a material financial risk to PB
III.  For example, the failure to achieve Year 2000 compliance by an exchange on
which PB III has an open position may cause PB III to be unable to close out
that position, or to somehow lose that open position if the failure to achieve
Year 2000 compliance makes the exchange unable to identify the fact that PB III
had an open position.     

    
     The general partner intends to monitor the progress of First Options of
Chicago, Inc. and of the exchanges and other trading markets for their Year 2000
compliance.  If the general partner is able to determine that First Options of
Chicago, Inc. or any exchange or other trading market will not be Year 2000
compliant by January 1, 2000, the general partner will direct Quiet Systems
Limited to close out some or all of PB III's then open positions, and to wait to
reinstitute trading until otherwise directed by the general partner.  This type
of action would likely be inconsistent with Quiet Systems Limited's trading
approach, and may result in substantial losses to PB III.  There is also no
guarantee that the above steps will be sufficient to avoid any adverse results
to PB III due to the failure of any third parties to achieve Year 2000
compliance.     

    
     The High Degree of Leverage Used in Futures Trading Increases the Risk of
     -------------------------------------------------------------------------
Sudden, Major Losses. The low margin deposits normally required in futures
- --------------------
trading permit an extremely high degree of leverage. A small adverse price
movement in a futures contract could result in a substantial loss to PB III,
greatly exceeding its margin on the trade. PB III may hold positions with a face
value exceeding the net assets of PB III, and even a slight adverse movement in
the prices of PB III's open positions could result in losses exceeding PB III's
net assets.    
    
     Quiet Systems Limited will utilize leverage in trading PB III's account,
and it is currently contemplated that from between 5% to 25% of PB III's net
assets will be committed as margin at any one time.     

                                      12
<PAGE>
 
    
The amount of PB III's net assets committed as margin may, however, at times
greatly exceed those percentages. Any increase in leverage will increase the
risks to PB III.     

    
     

    
     Illiquid Markets Could Make It Impossible to Realize Profits or Limit 
     ---------------------------------------------------------------------
Losses. The futures markets will sometimes be illiquid. In illiquid markets, PB
- ------
III may not be able to execute a buy or sell order at the desired price, or to
close out an open position in a timely manner.     
    
     Market illiquidity can arise from the various regulations that are
applicable to futures trading, such as the "daily price fluctuation limits" or
"daily limits" regulations. The daily limits are the maximum amount the price of
a futures contract may vary either up or down from the previous day's settlement
price. No trades may be made at a price beyond the daily limits.    
    
     Market illiquidity also occurs in a "thin" market where little trading is
taking place.  Market illiquidity can also occur because many trading approaches
use similar analyses.  This can lead to the bunching of buy and sell orders,
which makes it more difficult for a position to be taken or liquidated.  It is
also possible that an exchange or the Commodity Futures Trading Commission may
suspend trading in a particular contract, order immediate liquidation and
settlement of a particular contract, or order that trading in a particular
contract be conducted for liquidation only.     

                                       13
<PAGE>
 
    
     PB III may even be required in extreme circumstances to make or take
delivery of the interest underlying a particular position if the position cannot
be offset or liquidated prior to its expiration date.     

     
     

    
     PB III Could Lose Assets or Have Its Trading Disrupted Due to the Failure
     -------------------------------------------------------------------------  
of Exchanges or Brokers.  PB III is subject to the risk of failure of any of
- ------------------------
the exchanges on which it trades and of their clearinghouses. PB III is also
subject to the loss of its funds on deposit with its futures commission
merchant. For example, if its futures commission merchant became insolvent or
bankrupt, it is likely that PB III would be able to recover none or only a small
portion of its assets held by its futures commission merchant. None of these
factors or occurrences can be controlled by Quiet Systems Limited or PB III.    
   
     PB III will Trade on Foreign Exchanges That are Less Regulated than U.S. 
     ----------------------------------------------------------------------- 
Markets and are Subject to Risks That Don't Always Apply to U.S. Markets. PB III
- ------------------------------------------------------------------------
will trade on exchanges located outside the United States. The regulations of
the Commodity Futures Trading Commission do not apply to trading on foreign
exchanges, and trading on foreign exchanges may involve different and greater
risks than trading on United States exchanges. For example, on some foreign
exchanges the performance on a contract is the responsibility only of the
individual member with whom the trader has entered into the contract, and not of
the exchange. PB III will be subject to the risk of the inability or refusal by
any such member to perform on the contract. Foreign markets are also much more
susceptible to disruption than United States exchanges due to the lack of a
clearinghouse system in foreign markets.    
    
     Trading on foreign exchanges also involves certain risks that are not
applicable to trading on United States exchanges.  Those risks include:     

    
     *    varying exchange rates,
     *    exchange controls,
     *    expropriation,
     *    burdensome or confiscatory taxation,
     *    moratoriums, and
     *    political or diplomatic events.     

                                       14
<PAGE>
 
     Some foreign markets are also newly formed and may lack personnel
experienced in floor trading or in monitoring floor trades for compliance with
any foreign exchange rules.

    
     It will also likely be more costly and difficult for PB III to enforce the
laws or regulations of a foreign country or exchange, and it is possible that
the foreign country or exchange may not have laws or regulations which
adequately protect the rights and interests of PB III.       


    
     PB III May Trade in Forward Contracts That are Less Regulated and Involve 
     -------------------------------------------------------------------------
More Risks Than Trading on Exchanges.  Although it is unlikely to occur for some
- ------------------------------------
time, Quiet Systems Limited may cause PB III to trade currencies through forward
contracts in the interbank markets. Banks and dealers act as principals in the
forward contract markets, and forward contracts are not traded on exchanges. PB
III will be subject to the risk of the refusal or failure to perform by the
other party to a forward contract. This risk is not as great when trading on
exchanges because of the various regulatory and other protections that are
available when trading on exchanges and through their clearinghouses. Also,
although banks may be involved with forward contracts, trading in forward
contracts is not regulated by the various domestic and foreign banking
authorities. Trading in forward contracts is also not regulated by the Commodity
Futures Trading Commission. Daily price limits and speculative position limits
also do not apply to forward contracts.    
    
     

                                       15

     PB III's Trading Could be Adversely Affected by Speculative Position
     --------------------------------------------------------------------
Limits. The Commodity Futures Trading Commission and the United States exchanges
- ------
have established "speculative position limits" or "position limits" on the
maximum open positions which any person or group of persons may own or control
in particular futures contracts.    
    
     All accounts owned or managed by a trading advisor and the advisor's
principals and affiliates will be combined for position limit purposes. Quiet
Systems Limited believes that at some point it could face difficulties with
established position limits. If that occurs, Quiet Systems Limited's trading
program may have to be modified, which may have an adverse effect on the
operation and profitability of the trading program and PB III.     
    
     

                                       16

     Quiet Systems Analyzes Only Technical Market Data, Not Any Economic or 
     ----------------------------------------------------------------------    
Other Market Factors. A technical trading system generates buy and sell 
- ---------------------
signals which are primarily based upon a study of actual daily, weekly and
monthly price fluctuations, volume variations and changes and other related
mathematical, statistical or quantitative data utilizing charts and computer
programs.    
    
     Quiet Systems Limited's trading program is a computerized, technical
trading system.     

    
     The profitability of Quiet Systems Limited's trading program depends upon
the occurrence and accurate forecasting of significant sustained and discernable
price movements or trends.  Periods without moves or trends will lead to losses.
There have been periods without sustained and discernable trends in the past and
such periods will occur again in the future.     

    
     The occurrence of any factor which lessens the prospect of major trends
occurring in the future may also adversely affect the trading program.  Any
increase in the use of similar trading approaches may alter historical trading
patterns which may also adversely affect Quiet Systems Limited's trading
program.    
    
     In addition, a technical trading approach may under perform other trading
approaches when fundamental factors dominate price moves because a technical
trading approach may be unable to respond to fundamental events until after
their impact has ceased to influence the markets.    A technical trading
approach may also be ineffective and lead to losses in markets subject to random
price fluctuations, rather than defined trends or patterns.  There have been
periods in the past when the markets have been subject to large, random price
movements.  Those types of periods will occur again in the future.  A technical
trading approach may also have difficulty in taking into account the numerous
and varied factors which can affect prices and price movements.     

    
     No assurance is given that Quiet Systems Limited's trading program will be
successful under any market conditions.  You should note that there are always
     

                                      17
<PAGE>
 
    
two parties to a futures contract. If one party to the contract experiences a
gain on the contract, the other party to the contract experiences an equal
amount of loss. Only 50% of futures contracts can experience gain, and that gain
will be lowered and might be eliminated by commissions and other costs of
trading and other fees. Quiet Systems Limited's trading decisions will be
incorrect in many instances, and PB III will enter into positions which will
result in substantial losses for PB III.    
    
     Competition From Other Traders Could Reduce PB III's Profitability. 
     ------------------------------------------------------------------
Futures trading is highly competitive. PB III will be competing with others who
may have greater experience, more extensive information about and access to
developments affecting the markets, more sophisticated means of analyzing and
interpreting the markets, and greater financial resources. PB III's competitors
include commodity warehousemen, dealers, professional farmers, international
traders, representatives of governments, users of commodities, other pools, and
other trading advisors.    
    
     PB III may also experience increased competition for its trades if a
significant number of other traders use trading methods which are similar to
those used by Quiet Systems Limited.     

Risks Relating to PB III and the Offering of Units:
- -------------------------------------------------- 

    
     There are Conflicts of Interest in PB III's Structure. Although the general
     -----------------------------------------------------
partner does not believe any material conflict of interest exists which in
practice will be detrimental to PB III, conflicts of interest do exist in the
structure and operation of PB III. The various conflicts are discussed in
"Conflicts of Interest" below. The conflicts include that Mr. Raun is
financially interested in Quiet Systems Limited.    
    
     

    
     The General Partner Will Receive Fees Even if PB III is Unprofitable. The
     ---------------------------------------------------------------------
general partner will receive its management fee whether or not PB III is
profitable.    

                                      18
<PAGE>
 
    
     Since the incentive fee payable to the general partner will be determined
quarterly, PB III may pay a substantial incentive fee for a quarter despite a
subsequent decline in PB III's net assets.     
    
     The incentive fee and management fee are partially based upon any increased
value in PB III's open positions.  This value may never be realized by PB III
because the prices of its open positions could later decline.  All fees paid to
the general partner will be retained by the general partner even if PB III
subsequently realizes losses when the open positions upon which the fees were
paid are closed.     
    
     

    
     

    
     

    
     PB III Relies on Frischmeyer Trading Corporation But May Lose Its Services 
     --------------------------------------------------------------------------
At Any Time.  PB III will rely upon Frischmeyer Trading Corporation for
- ------------                                                       
communicating the trading signals generated by the software utilized in the
trading program to PB III's futures commission merchant. If Frischmeyer Trading
Corporation terminates or otherwise becomes unable to continue to provide
services to PB III, another person or entity will have to be selected to provide
those services. No guarantee can be given that any    

                                      19
<PAGE>
 
    
replacement will perform as well as Frischmeyer Trading Corporation or can be
retained on the same terms as currently in effect with Frischmeyer Trading
Corporation.    
    
     Frischmeyer Trading Corporation relies upon a key person for providing
services to PB III.  If that person terminates or otherwise becomes unable
(through death, disability, etc.) to continue to provide services to Frischmeyer
Trading Corporation, the ability of Frischmeyer Trading Corporation to provide
services to PB III may be adversely affected in a material way.     
    
     
    
       The Units May Not Be a Liquid Investment. Units are not freely 
       -----------------------------------------
transferable. They can only be assigned or transferred upon the terms and
conditions set forth in the limited partnership agreement. Those restrictions
may at times preclude a transfer of a unit.    
    
     Substantial restrictions and conditions are also imposed upon the
liquidation of units. For example, the general partner may require a limited
partner to provide up to 60 days prior written notice of the limited partner's
desire to liquidate units. Given the volatility of the futures markets, the net
asset value per unit could decline significantly during that period.
Liquidations may also be honored only in part and delayed or suspended in
various circumstances.    
    
     Substantial liquidations of units could require PB III to liquidate open
positions more rapidly than otherwise desirable in order to raise the cash to
fund the liquidations, while at the same time achieving a market position
appropriately reflecting a smaller equity base.  Illiquidity in the market could
also make it difficult to liquidate positions on favorable terms, which could
result in losses to PB III.     
    
     Limited partners will have to depend on their limited and restricted
transfer and liquidation rights in order to realize on their investment in the
units because it is likely that no distributions will ever be made to the
limited partners.     
    
     Under certain limited circumstances PB III may make a claim against a
limited partner for funds received by the limited partner from PB III.

     Quiet Systems Trading Program is not Diversified Because it Only Trades in 
     --------------------------------------------------------------------------
Certain Currencies.  Trading in Quiet Systems Limited's trading program will 
- -------------------
currently be limited to interests in various currencies. PB III therefore will
not participate in a diversified range of markets.    
    
     Limited Partners Will Not Participate in the Management of PB III. 
     ------------------------------------------------------------------        
Limited partners will not participate in the control or management of PB III or
its business. For example, distributions to the limited partners will only be
made in the sole discretion of the general partner.    
    
     
    
     
    
     This Offering May Be Unsuccessful for Various Reasons. There is no 
     ------------------------------------------------------
assurance that all or any portion of the units available in this offering will
be sold. Vacation Investors, Inc. and the general partner do not have any
obligation to purchase any units.    
    
     The general partner has the right to withdraw or modify this offering.  The
general partner may also partially or totally reject any subscription.  There
are minimum investment, net worth and suitability standards that must be met in
order for the general partner to be able to accept a subscription so the number
of investors who qualify for investment in PB III is limited.     

                                      21

     Vacation Investors, Inc. has limited experience in public offerings.     
    
     Funds Contributed Before PB III Breaks Escrow May Sit Idle For Some Time. 
     -------------------------------------------------------------------------
PB III cannot commence trading until 500 units are sold. PB III has until
October 28, 1999 to sell the 500 units.    
    
     PB III Has No Operating History For You to Consider.  PB III had not 
     ----------------------------------------------------                       
commenced trading and had no operating or performance history as of the date of
this prospectus. Quiet Systems Limited also had no operating history as of the
date of this prospectus.     
    
     The Start-Up of PB III's Trading Will Involve Risks Not Applicable to 
     ---------------------------------------------------------------------
Established Pools. PB III will encounter a start-up period during which it 
- ------------------
will incur certain risks relating to the initial investment of its assets. PB
III may commence trading at an inopportune time, such as after sustained moves
in the markets, resulting in significant initial losses. The start-up period
also represents a special risk because the level of diversification of PB III's
assets may be lower than in a fully-committed portfolio.    
    
     Investing in the Units Might Not Diversify an Overall Portfolio. One of the

objectives of PB III is to add a valuable element of diversification to a
traditional securities and bond portfolio. While PB III may perform in a manner
largely independent from the general stock and bond markets, there is no
assurance it will do so. An investment in PB III could increase rather than
reduce overall portfolio losses during periods when PB III and stocks and bonds
decline in value. There is no way of predicting whether PB III will lose more or
less than stocks and bonds in declining markets. You must not rely on PB III as
any form of hedge against losses in your securities and bond portfolios. You
should consider whether diversification in itself is worthwhile even if PB III
is unprofitable.

     The General Partner May Resign at Any time, Which Could Result in the Need 
     --------------------------------------------------------------------------
to Terminate PB III. Limited partners will be relying entirely on the ability 
- --------------------                                            
of the general partner to manage PB III.     
    
     There is no assurance that the general partner will continue to provide
services to PB III because the general partner may withdraw as the general
partner of PB III without the consent of the limited partners.     
    
     Mr. Raun is the President and key employee of the general partner. If 
Mr. Raun discontinues his services to the general partner or otherwise becomes
unable to provide services to the general partner (through death, disability,
etc.), the general partner will be unable to continue to manage the business of
PB III unless it is able to retain another qualified employee.    
   
     The Purchase of Units by the General Partner or Mr. Raun Will Create 
     --------------------------------------------------------------------   
Conflicts of Interest for Them. The General Partner and Mr. Raun may 
- -------------------------------
purchase units for their own account. Any purchase of units by the general
partner or Mr. Raun should not be relied upon as an indication of the merits of
this offering.    

                                      22

<PAGE>
 
    
     Conflicts of interest will arise if the general partner and/or Mr. Raun
hold a substantial number of units, because the general partner and Mr. Raun
will then be in a position to substantially influence matters submitted to a
vote of the limited partners.  For example, conflicts of interest could arise
regarding the dissolution of PB III because the dissolution of PB III would
terminate the general partner's compensation from PB III.  Any investments in PB
III by affiliates or family members of  the general partner or Mr. Raun could
increase the risks discussed in this paragraph.  As of the date of this
prospectus, however, the general partner had not purchased any units, and Mr.
Raun had purchased only $1,000 of units in his capacity as the initial limited
partner of PB III.  The latter amount will be returned to Mr. Raun upon the
admission of the first limited partner.     
    
     The Nonvoting Members of the General Partner Do Not Have Experience in
     -----------------------------------------------------------------------
Managing a Pool. The general partner has 3 nonvoting members.  The nonvoting 
- ---------------
members do not have voting rights, except in very limited circumstances. It is
possible, therefore, that the nonvoting members of the general partner may at
some point have the ability to participate in the management of the general
partner. This could have adverse effects to PB III because none of the nonvoting
members have any experience in the management or operation of a pool such as PB
III. It is contemplated, however, that even if a circumstance arises in which
the nonvoting members may participate in the management of the general partner,
Mr. Raun will still continue to be the sole officer of the general partner and
will continue to be responsible for the day-to-day operation of the general
partner's business as it relates to PB III.    
   
     The nonvoting members of the general partner may purchase units. The risks
noted in "The Purchase of Units by the General Partner or Mr. Raun Will Create
Conflicts of Interest for Them" above are therefore also potentially applicable
to the nonvoting members.    
    
     You May Not Be Able to Use a Vacation Award Even if You Have Qualified
     ----------------------------------------------------------------------
for One. One requirement that must be met in order to qualify for any of the
- --------
vacation awards discussed in "Vacation Award" below, is that the limited partner
be a limited partner in at least 3 limited partnerships for which the general
partner serves as the commodity pool operator. As of the date of this
prospectus, the only limited partnerships of the general partner which were open
to investors were PB III, Portfolio Boost I, L.P. and Portfolio Boost II, L.P.
The general partner is also the commodity pool operator of CBC-RT. CBC-RT is
not, however, open to new investors. You therefore need to become a limited
partner in PB III and in Portfolio Boost I, L.P. and Portfolio Boost II, L.P. in
order to be able to qualify for any of the vacation awards, unless you are
already a limited partner in CBC-RT. If you are a limited partner in CBC-RT, you
would need to become a limited partner in any two of PB III, Portfolio Boost I,
L.P. or Portfolio Boost II, L.P.    
    
     Unforeseen financial difficulties could arise which could prevent the
general partner from being able to satisfy its obligation to provide the
vacation awards.  Weather and other      

                                      23
<PAGE>
 
    
factors beyond the general partner's control may also prevent a qualifying
limited partner from being able to take any vacation award.     

Taxation, Regulatory and Other Risks:
- ------------------------------------ 
    
     Limited Partners Will Owe Taxes on PB III's Profits But Will Very Likely 
     ------------------------------------------------------------------------
Never Receive Any Distributions From PB III. PB III is not required to make
- --------------------------------------------
any distributions, and it is likely that no distributions will ever be made
because the principal objective of PB III is to increase capital, not create
cash flow.    
    
     Any PB III profits will be taxable to you in accordance with your
distributive share of PB III profits, whether or not the profits have been
distributed.  Even if distributions are made, the distributions may not equal
the taxes payable by you on your share of PB III's profits.

     PB III might sustain losses offsetting the profits of a prior fiscal year,
so you might never receive a distribution or be able to liquidate your units for
an amount equal to the taxes which have already been paid by you.    
    
     

                                      24

<PAGE>
 
    
     
    
     The Tax Laws May Change to the Detriment of PB III and its Limited 
     ------------------------------------------------------------------
Partners. It is possible that the current federal income tax treatment accorded
- --------- 
an investment in the units will be modified by subsequent legislative,
administrative or judicial action. Any such changes could significantly alter
the tax consequences and decrease the after-tax rate of return on an investment
in the units.    
    
     Other Laws and Circumstances Regarding the Futures Markets Will Change and
     --------------------------------------------------------------------------
May Adversely Affect PB III's Trading. The regulation of the United States and 
- --------------------------------------
foreign futures markets has undergone substantial change over the years, and
further changes should be expected. It is impossible to predict, however, what
changes may occur, or the effect of any such changes on PB III. The effects
could be substantial and adverse.    
    
     The number of markets available for trading is increasing and will continue
to increase and also change in other ways, any of which may also have adverse
consequences to Quiet Systems Limited's trading program and to PB III.     
    
     
    
     PB III's and Limited Partners' Tax Returns May Be Audited. There is no 
     ----------------------------------------------------------
assurance that PB III's tax return will not be audited by the Internal Revenue
Service or that adjustments to PB III's return will not be required as a result
of an audit. If an audit results in an adjustment, limited partners may be
required to file amended returns (which may themselves also be audited) and to
pay back taxes, plus interest and possibly penalties.

     The foregoing discussion is not a complete list or explanation of the risks
involved in this offering. Additional risks may be experienced which are not
presently foreseen by PB III. You are not to construe this prospectus as legal
or tax advice. Before determining to invest in the units, you should read this
entire prospectus, including its exhibits, and consult with your own personal
investment, legal, tax and other professional advisors.    


                             CONFLICTS OF INTEREST
                             ---------------------
    
     Significant conflicts of interest exist in the structure and operation of
PB III.  PB III has used its best efforts to describe the principal conflicts of
interest in this section and elsewhere in this prospectus.  (See, e.g.
                                                             ---      
"Principal Risk Factors" above.)  Although the general partner will attempt to
examine these conflicts of interest, no formal procedures have been established
to monitor or resolve any conflicts of interest and there is no assurance that
any conflict of interest will not result in adverse consequences to PB III.     
    
     Mr. Raun is Financially Interested in Quiet Systems Limited.  All of the
     -----------------------------------------------------------             
issued stock of Quiet Systems Limited is owned by a Cayman Islands trust, as
discussed in "The CTA-Quiet Systems Limited" below.  The trust has several
beneficiaries.  Mr. Raun and members of his family are some of those
beneficiaries.  Mr. Raun and his family do not control the trust, but they will
benefit from any compensation payable to Quiet Systems Limited since they are
beneficiaries of the trust.  As a beneficiary, Mr. Raun will have a personal
interest in PB III continuing to use Quiet Systems Limited as the sole trading
advisor of PB III.  Mr. Raun will also have the authority on behalf of the
general partner to make all decisions regarding trading advisors for PB III.  He
therefore has a conflict of interest in determining whether PB III should
terminate the services of Quiet Systems Limited or add additional trading
advisors.  Mr. Raun is aware of this conflict of interest, however, and will
utilize his best efforts to make determinations regarding these issues
independent of any personal considerations.     
    
     

                                      26

<PAGE>
 
    
     It is not uncommon for pools to experience losses from trading for many
consecutive months or for many of the months in any given one year or longer
period.  The general partner is not required to retain additional trading
advisors or to replace Quiet Systems Limited simply because PB III has
experienced substantial losses from its trading.     
    
     
    
     Trading Decisions of Quiet Systems Limited. Quiet Systems Limited will
     ------------------------------------------                             
determine all of PB III's trades.  Quiet Systems Limited may also effect trades
for its own account and will be effecting trades for others.  A conflict of
interest arises from this fact because it is possible that other positions taken
by Quiet Systems Limited may be taken ahead of or opposite to positions taken on
behalf of PB    

                                      27

<PAGE>
 
    
III. It is the general partner's belief, however, that Quiet Systems Limited
will not knowingly trade for its own or another's account ahead of PB III's
account. It should be noted, however, that the trading decisions generated in
Quiet Systems Limited's other trading programs may be different from those made
in Quiet Systems Limited's trading program in which PB III's account is traded.
PB III may therefore hold positions opposite of those held in one of Quiet
Systems Limited's other trading programs.     
    
     The various accounts being traded by Quiet Systems Limited will be
competing for the same positions. Depending on market liquidity and other
factors, this could result in orders for PB III being executed at prices less
favorable than would otherwise be the case. It could also result in the orders
of other clients of Quiet Systems Limited being executed when similar trades for
PB III are not executed. These possibilities will increase if the trading
decisions in Quiet Systems Limited's other trading programs are the same as
those made in the trading program in which PB III's account is traded, and if
Quiet Systems Limited's own accounts are also making the same trades.    
    
     
    
     Quiet Systems Limited may determine the manner in which orders will be
entered or filled. There is no assurance PB III's performance will not be
adversely affected by the manner in which orders are entered or filled by Quiet
Systems Limited. It is the general partner's belief, however, that Quiet Systems
Limited will use an allocation system that Quiet Systems Limited in good faith
believes is equitable and systematic.    
    
     Other Business of Quiet Systems Limited.  Quiet Systems Limited uses
     ---------------------------------------                             
systematic trading methods that require little human involvement on a regular
basis.  Quiet Systems Limited is not required to devote its full time or
attention to the trading program or PB III's account, and Quiet Systems Limited
will be involved in other futures related businesses and possibly other
businesses or ventures.  Quiet Systems Limited will therefore experience
conflicts of interest in allocating its time and      

                                      28

<PAGE>
 
    
services between the trading program and Quiet Systems Limited's other business
ventures, such as the other trading programs offered by Quiet Systems Limited.
Quiet Systems Limited may have financial or other incentives to favor other
trading programs, accounts or businesses over PB III. For example, Quiet Systems
Limited's other trading programs may have better trading results than the
trading program in which PB III's account is traded. This fact may cause Quiet
Systems Limited to devote more attention to the other trading programs. Quiet
Systems Limited's other trading programs may have better trading results because
of, for example, the trading approach being used or because Quiet Systems
Limited imposes lower fees in its other trading programs.     
    
     Key Persons of Quiet Systems Limited.  Quiet Systems Limited relies upon
     ------------------------------------                                    
certain key persons for the proper operation of its business.  Those persons may
provide services to others and may also effect trades for their own account and
for others.  Those persons are not required to devote their full time or
attention to the services they provide to Quiet Systems Limited.  The conflicts
of interests noted in "Trading Decisions of Quiet Systems Limited" and "Other
Business of Quiet Systems Limited" immediately above are therefore also
applicable to those persons.     
    
     Other Business of Frischmeyer Trading Corporation.  Frischmeyer Trading
     -------------------------------------------------                      
Corporation is not required to devote its full time or attention to the services
it will provide to PB III, and Frischmeyer Trading Corporation and its key
persons will be providing trading advice and related services to others as well
as effecting trades for their own and others' accounts.  The conflicts of
interest noted in "Trading Decisions of Quiet Systems Limited" and "Other
Business of Quiet Systems Limited" above are also applicable to Frischmeyer
Trading Corporation and its key persons.     
    
     Agreements Required by Quiet Systems Limited.  PB III was required to enter
     --------------------------------------------                               
into an Advisory Agreement with Quiet Systems Limited.  The Advisory Agreement
provides that Quiet Systems Limited will have no liability to PB III except only
for acts or omissions constituting willful misconduct or fraud.  The Advisory
Agreement also provides that Quiet Systems Limited shall have no liability for
any acts or omissions which are in any way  restricted or affected by any:
     
    
     .    communication line failure,
     .    computer failure,
     .    power failure,
     .    mechanical failure,
     .    equipment malfunction or failure,
     .    computer virus,
     .    software error or interruption,
     .    act or omission of any third party, or
     .    other factors beyond the reasonable control of Quiet Systems Limited.
     

                                      29

<PAGE>
 
    
The Advisory Agreement also provides that PB III bears the risk of all errors
and problems of its futures commission merchant, Frischmeyer Trading
Corporation, any exchange or clearinghouse and all other third parties.  The
Advisory Agreement also obligates PB III to defend and indemnify Quiet Systems
Limited and its affiliates against various losses, liabilities, costs and
expenses.  The Advisory Agreement also provides that any action or proceeding on
any dispute between PB III and Quiet Systems Limited must be commenced within 1
year, or any claims on the dispute will be lost and forever barred.  The
Advisory Agreement also provides that any dispute between PB III and Quiet
Systems Limited shall be resolved on Grand Cayman, in the Cayman Islands,
British West Indies.  These provisions of the Advisory Agreement are all very
favorable to Quiet Systems Limited.  PB III does not believe, however, that the
provisions of the Advisory Agreement will change or affect the trading decisions
that Quiet Systems Limited would otherwise make on behalf of PB III.     
    
     Agreement With Frischmeyer Trading Corporation.  PB III was also required
     ----------------------------------------------                           
to enter into an agreement with Frischmeyer Trading Corporation.  The agreement
provides that Frischmeyer Trading Corporation shall not be liable to PB III for
any losses of PB III unless the losses are directly caused by Frischmeyer
Trading Corporation's gross negligence or willful misconduct as finally
adjudicated by a court of competent jurisdiction.  The agreement also provides
that any dispute between PB III and Frischmeyer Trading Corporation must be
resolved in Fort Dodge, Webster County, Iowa.  These provisions are all very
favorable to Frischmeyer Trading Corporation.  PB III does not believe, however,
that the provisions of the agreement will change or affect the nature or quality
of the services that Frischmeyer Trading Corporation would otherwise provide to
PB III.  Frischmeyer Trading Corporation will be acting as PB III's agent, and
Quiet Systems Limited has no liability or responsibility for any acts or
omissions of Frischmeyer Trading Corporation.     
    
     
    
     Distribution and Liquidation Decisions by the General Partner.  The general
     -------------------------------------------------------------              
partner will determine whether PB III will make any distributions to the limited
partners.  The general partner will be financially motivated to not declare any
     

                                      30

<PAGE>
 
    
distributions  because distributions will lower the net assets of PB III, which
will in turn reduce the amount of the monthly management fee which is payable to
the general partner by PB III.  Any decrease in the net assets of PB III will
also indirectly lower the amount of incentive fees payable to the general
partner.  The general partner will also have an incentive to discourage
liquidation of units by any limited partner for the same reason.     
    
     Distributions and liquidations will lower the fees payable by the general
partner to Quiet Systems Limited.  This fact may also affect distribution and
liquidation decisions of the general partner because Mr. Raun and members of his
family are financially interested in the compensation payable to Quiet Systems
Limited.  See "Conflicts of Interest--Mr. Raun is Financially Interested in
          ---                                                              
Quiet Systems Limited" above.     
    
     The general partner is aware of these conflicts of interest and will use
its best efforts to make determinations about distributions and liquidation of
units independent of its personal considerations regarding its compensation or
Quiet Systems Limited's compensation.  You need to remember, however, that the
principal objective of PB III is to generate increased capital, so it is very
likely that no distributions will ever be made to the limited partners.   An
investment in PB III must only be viewed as a long term investment.     
    
     Performance Records Not Independently Prepared.  The performance
     ----------------------------------------------                  
information in this prospectus was prepared by the general partner or Quiet
Systems Limited, and has not been audited or otherwise confirmed by any 
independent party.  This is also true about any other performance information 
that may be provided to you in connection with your consideration of an 
investment in the units.  All performance information does, however, 
accurately reflect the performance for the periods shown.     
    
     Other Pools and Business of the General Partner and Mr. Raun.  The general
     ------------------------------------------------------------              
partner is the general partner and commodity pool operator for 4 other limited
partnerships.  The general partner also contemplates serving as the general
partner and commodity pool operator for other pools in the future.  Mr. Raun is
the general partner and commodity pool operator for 4 limited partnerships and
is the sole owner, director and officer of Vacation Investors, Inc.  Both the
general partner and Mr. Raun may also be involved with other businesses.  The
general partner will not spend its entire time managing the business of PB III,
and Mr. Raun will not spend his full time managing the business and affairs of
the general partner.  The general partner believes, however, that its time
available for the management of PB III's business will be sufficient for the
general partner to fulfill its duties and obligations to PB III.  The general
partner also believes that Mr. Raun's time available for the management of the
general partner will be adequate to fully perform his duties to the general
partner.     

                                      31

<PAGE>
 
    
     No assurance is given that PB III's performance will be better or worse
than any other pool managed by the general partner or Mr. Raun.     
    
     The Underwriter.  Vacation Investors, Inc. is the underwriter for PB III's
     ---------------                                                           
offering.  Mr. Raun is one of the registered representatives of Vacation
Investors, Inc., and he will be offering the units pursuant to his registration
with Vacation Investors, Inc.  Mr. Raun is also the sole shareholder, director
and officer of Vacation Investors, Inc.  The general partner does not believe
that any material conflict of interest exists because of Mr. Raun's ownership of
and position with  Vacation Investors, Inc. because there will be no
underwriting commissions or other fees payable to Vacation Investors, Inc. by PB
III.     
    
     Vacation Investors, Inc. will receive compensation from the general
partner, as discussed in "Plan of Distribution" below.  Since Mr. Raun is the
sole shareholder of Vacation Investors, Inc., Mr. Raun is interested in that
compensation.  The general partner does not believe that any material conflicts
of interest are presented by this fact, however, because any compensation which
is paid to Vacation Investors, Inc. will be paid by the general partner, and not
by PB III.  Payments by the general partner to Vacation Investors, Inc. will
reduce the profits of the general partner.  This affects Mr. Raun individually
given that he is the sole owner of the corporation that holds all of the voting
units of the general partner.  Also, it is currently contemplated that there
will not be any material profits generated in Vacation Investors, Inc.  This is
because the payments by the general partner to Vacation Investors, Inc. will
either be paid out to the registered representatives of Vacation Investors, Inc.
or used by Vacation Investors, Inc. to offset out-of-pocket costs and 
expenses.     
    
     Other Pools and Trading by the General Partner and the Members of the
     ---------------------------------------------------------------------
General Partner.  The general partner may manage additional pools in the future
- ---------------                                                                
and the general partner and the members of the general partner may trade for
their own and others' accounts.  This creates a potential conflict of interest
because it is possible that positions taken by the general partner or its
members for their own or others' accounts may be the same as or may be taken
ahead of or opposite positions taken on behalf of PB III.  The general partner
and its members will not, however, knowingly trade for their own or another's
account ahead of PB III's account.     

    
     

                                      32

<PAGE>
 
   
     
                FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER
                -----------------------------------------------
    
     The general partner has a fiduciary duty to the limited partners.  If a
limited partner believes the general partner has violated its fiduciary duty,
the limited partner may seek to recover damages from or require an accounting by
the general partner.  It will, however, be difficult to recover damages based
upon a claim that PB III's trading has been excessive because of the broad
trading authority given to Quiet Systems Limited and the absence of judicial
decisions providing clear standards for defining excessive trading or churning.
The general partner's performance of its fiduciary duty will also be measured by
the terms of PB III's limited partnership agreement.  Some provisions of the
limited partnership agreement may take away or limit some of the legal remedies
that might otherwise be available to limited partners.  Those provisions are
summarized in the following paragraphs.     
    
     Limited partners may also have the right to bring an arbitration,
reparations or other legal proceeding against the general partner if the general
partner violates any applicable laws or regulations, like the Commodity Exchange
Act or the regulations of the Commodity Futures Trading Commission.     

     Limited partners who have questions concerning the responsibilities of the
general partner should consult their own legal counsel.
    
     As mentioned above, some provisions of PB III's limited partnership
agreement may take away or limit some of the legal remedies that might be
available to limited partners.  For example, the limited partnership agreement
provides that the general partner will not be liable for damages to PB III or
any of the limited partners except for acts or omissions which constitute
negligence or misconduct.  The general partner's defenses to any claim that the
general partner has breached any fiduciary duty or other responsibility will
therefore include that the general partner's act or omission was not negligent
and did not involve any misconduct.  The limited partnership agreement also
provides that the general partner will not be liable for any adjustments in PB
III's or any limited partner's income tax returns, or for the return or
repayment of the capital contributions or profits of any limited partner.  Any
return of capital or profits will be made solely from the assets of PB III, and
not by the general partner.     

                                      33

<PAGE>
 
    
     The limited partnership agreement also provides that PB III will indemnify
the general partner against any loss, liability, damage, cost or expense
(including court costs, arbitration costs, attorneys' and accountants' fees and
expenses) incurred by the general partner, so long as the general partner acted
in good faith and in a manner the general partner reasonably believed to be in,
or not opposed to, the best interests of PB III, and the conduct in question did
not constitute negligence or misconduct.     
    
     The limited partnership agreement establishes additional conditions that
must be met before the general partner can be indemnified for any losses,
liabilities, damages, costs or expenses arising from any violation of federal or
state securities laws. PB III has been advised, however, that in the opinion of
the Securities and Exchange Commission, any indemnification of the general
partner or its affiliates for any liabilities under the Securities Act of 1933
would be against public policy as expressed in that Act and, therefore, is
unenforceable.     
    
     The limited partnership agreement authorizes the advancement of costs and
expenses to the general partner, subject to certain conditions specified in the
limited partnership agreement.     
    
     The provisions of the limited partnership agreement discussed in this
section are also applicable to and benefit any affiliate of the general partner
when the affiliate is performing services on behalf of PB III.  The term
"affiliate" for this purpose is defined in the limited partnership agreement,
and will include Mr. Raun.     
    
     The provisions of the limited partnership agreement discussed in this
section will not be affected by the termination of PB III or the resignation,
removal, death, withdrawal, insolvency or dissolution of the general 
partner.     
    
     The payment by PB III of any indemnity to the general partner, Mr. Raun or
any of the general partner's other affiliates  will affect the limited partners
because the payment would reduce the net assets of PB III.     
    
     PB III will not carry any liability insurance covering its indemnification
obligations.

     Management Fee and Incentive Fee to General Partner.  The general partner
     ---------------------------------------------------                      
receives a monthly management fee of one-half of one percent (0.5%) of PB III's
net assets as of the close of business on the last business day of each month.
Net assets means all of PB III's assets, less all of its liabilities, determined
in accordance with generally accepted accounting principles and before accrual
of both the management fee and any incentive fee payable to the general partner.
The management fee is payable by PB III within 10 business days of the close of
each month.     
    
     The general partner will also receive a quarterly incentive fee of 15% of
the new trading profits, if any, of PB III for each quarter.  New trading
profits means the excess, if any, of the net assets of PB III at the end of a
quarter over the highest net assets of PB III at the end of any previous quarter
or on the date trading commences, whichever is higher.  Net assets will be
adjusted for this purpose to eliminate the effect of new capital contributions
or distributions or liquidations made during the quarter, and will be decreased
by any interest or other income earned on PB III's assets which is not directly
related to trading activity.  Net assets for this purpose will be determined
before accrual of the incentive fee, but including accrual of the management
fees payable to the general partner during the quarter.  The incentive fee is
payable as soon as is reasonably practicable following the close of each
quarter.     
    
     If PB III incurs a net loss during any quarter, no incentive fee will be
payable to the general partner until the loss has been offset by net profits in
succeeding quarters.  As an example, if in successive quarters PB III has new
trading profits of $2,000, $8,000, <$4,000>, <$3,000>, $2,000, and $8,000, the
incentive fee payable to the general partner will be, respectively, $300,
$1,200, $0, $0, $0, and $450.     
    
     The general partner will also be reimbursed by PB III for PB III expenses
which are paid by the general partner (such as delivery charges, copying costs,
telephone charges and postage).     
    
     The general partner will not receive any portion of the brokerage
commissions which are paid by PB III.     
    
     Futures Commission Merchant; Brokerage Commissions.  First Options of
     --------------------------------------------------                   
Chicago, Inc. is PB III's futures commission merchant.  LBS Limited Partnership
will, however, execute all of the trades of PB III, but will give up all of the
trades to First Options of Chicago, Inc. for clearing.  LBS Limited Partnership
and First Options of Chicago, Inc. will receive brokerage commissions in return
for their services      

                                      36

<PAGE>
 
    
as described in "Description of Charges to PB III--Allocation of Commissions"
below.     
    
     One-half (1/2) of the brokerage commissions will generally be paid by PB
III at the time the trade is established, with the remaining one-half (1/2) to
be paid on the liquidation of the trade.  The brokerage commissions are commonly
referred to as "round-turn commissions" which cover both the initial purchase
(or sale) of the futures contract and the subsequent offsetting sale (or
purchase).  The brokerage commissions payable by PB III are always subject to
change.     
    
     The round turn commission payable by PB III as of the date of this
prospectus was fixed at $11.00.  The general partner believes that is a
competitive rate.  The general partner estimates that the annual brokerage
commissions payable by PB III will amount to approximately 1.47% of PB III's net
assets at the fixed $11.00 rate.  No guaranty is given that annual brokerage
commissions will not exceed that percentage.     
    
     PB III will also pay First Options of Chicago, Inc. for all delivery,
insurance, storage and other charges incidental to trading.  Those types of
charges are not included in the percentage set forth in the preceding paragraph.
The general partner does not anticipate significant charges of this nature.     
    
     Allocation of Commissions.  It is not uncommon in the futures industry for
     -------------------------                                                 
brokerage commissions to be allocated among various parties, and the brokerage
commissions payable by PB III will be allocated between LBS Limited Partnership
and First Options of Chicago, Inc. pursuant to their own agreement.  PB III does
not control the allocation, and the allocation may be changed without the
knowledge or consent of PB III.  As indicated above, the commissions payable by
PB III were fixed at $11.00, round turn, as of the date of this prospectus.     
    
     Other Expenses.  PB III is obligated to pay legal, accounting and auditing
     --------------                                                            
fees, as well as any other expenses incurred by PB III, such as exchange and
National Futures Association fees, office supplies expenses and organizational
and offering expenses.     
    
     The National Futures Association fees payable by PB III as of the date of
this prospectus were $0.20 round turn.  Exchange fees vary, but the general
partner estimates that exchange fees may range anywhere from approximately $800
to $1,800 per year.     
    
     The general partner estimates that PB III will incur legal fees of $72,000
and accounting fees of $10,000 in this offering.  The general partner estimates
that PB III will incur ongoing annual legal fees and accounting and auditing
fees of approximately $25,000  and $21,000.   The organizational and offering
expenses (legal, accounting, printing, advertising, filing fees, etc.) to be
incurred by PB III in this offering are estimated to be $193,660.     
   
     PB III will be responsible for the payment of the escrow fee to First
American Bank under PB III's escrow agreement with First American Bank.  The
escrow fee will be the greater     

                                      37

<PAGE>
 
    
of (a) $300.00, or (b) an amount calculated by multiplying $5.00 by the number
of checks received or issued by First American Bank under the escrow 
agreement.     

     PB III estimates that it will pay filing fees of approximately $25,000 to
various federal and state authorities in connection with the registration of
this offering with those authorities.
    
     PB III will also be responsible for all other expenses incurred by PB III.
The other expenses may include extraordinary expenses such as the cost of
litigation in which PB III may be engaged.  By their nature, the dollar amount
of extraordinary expenses cannot be estimated with any reasonable certainty, but
they could be substantial.     
    
     The actual expenses incurred by PB III will be set forth in reports to the
limited partners.  See "Reports" below.     
                   ---                 
    
     The general partner will be reimbursed by PB III for PB III expenses paid
by the general partner (such as delivery charges, copying costs, telephone
charges and postage).     
    
     Quiet Systems and Vacation Investors Compensation.  The compensation
     -------------------------------------------------                   
payable to Quiet Systems Limited for its services to PB III will be paid by the
general partner, and PB III is not liable or responsible for Quiet Systems
Limited's compensation.  The current agreement is that the general partner will
pay Quiet Systems Limited a certain percentage of the management fees and
incentive fees which are paid to the general partner by PB III.     
    
     The compensation payable to Vacation Investors, Inc. for its services to PB
III is also payable by the general partner, and PB III is not liable or
responsible for Vacation Investors, Inc.'s compensation.  The current agreement
between the general partner and Vacation Investors, Inc. is described in "Plan
of Distribution" below.     
    
     Quiet Systems Limited and  Vacation Investors, Inc. will not receive any
brokerage commissions.     
    
     Frischmeyer Trading Corporation Compensation.  The compensation of
     --------------------------------------------                      
Frischmeyer Trading Corporation is also payable by the general partner, and PB
III is not liable or responsible for Frischmeyer Trading Corporation's
compensation.  Frischmeyer Trading Corporation will not receive any brokerage
commissions.     
   
     Reports.  The general partner will furnish each limited partner with a
     -------                                                               
monthly statement.  The statement will include, in general, a description of the
performance of PB III and will set forth the aggregate fees, brokerage
commissions, and other expenses incurred or accrued by PB III during the month.
PB III will also provide the limited partners with all other reports required
under the regulations of the Commodity Futures Trading Commission and under the
Securities Exchange Act of 1934.  Those

     Break Even Calculation.  The general partner estimates that the trading
     ----------------------                                                 
profit PB III must make on a $5,000 investment in order for a limited partner to
break even if the limited partner redeemed his or her units at the end of the
first year of investment is:     
    
     a.   $236 or 4.72%, if PB III had average annual net assets of $5,000,000;
     b.   $186 or 3.71%, if PB III had average annual net assets of $15,000,000;
          and
     c.   $176 or 3.52%, if PB III had average annual net assets of 
          $25,000,000.     
    
The calculations have been given for the various levels of net assets because
the amount of subscriptions received by PB III in this offering could vary
widely.     
    
     The following table and explanatory notes set forth the basis for and
calculation of the above figures.  The table is based on the fees as described

Explanatory Notes:
- ----------------- 
    
     1.  Units may be purchased at a price of $1,000 per unit until PB III
starts trading.  After that time, they may be purchased at a price per unit
equal to the net asset value per unit as of the opening of trading on the first
business day of a month.  The minimum initial investment is $5,000.     
    
     2.  The general partner receives a monthly management fee of one-half of
one percent (0.5%) [which equals 6% annually] of PB III's net assets as of the
close of business on the last business day of each month.  The above amounts are
annual amounts.     
    
     3.  The general partner also receives a quarterly incentive fee of 15% of
the new trading profits of PB III. No amount is shown above for incentive fees
because all fees and expenses payable by PB III are deducted before calculation
of the incentive fee.     
    
     4.  PB III's actual accounting, auditing, legal and other operating
expenses will be borne by PB III.  These expenses are estimated to amount to
approximately 1.87%, 0.86% and 0.66%, respectively, assuming annual average net
assets of $5,000,000, $15,000,000, and $25,000,000.  The expenses include
$193,660 as an estimate of the organizational and offering expenses for this
offering.  That amount has been amortized over a 5 year period for purposes of
the above calculations (i.e., at $3,228 per month) because amortization is
required under the terms of the limited partnership agreement as part of the
calculation of the net asset value per unit.     
    
     5.  Brokerage commissions, exchange and National Futures Association fees
and other trading fees are estimated at 1.85% of net assets.     
    
     6.  PB III will earn interest on treasury bills purchased and held in its
account with First Options of Chicago, Inc., and on funds held in PB III's bank
account.  Based on interest rates in effect as of the date of this prospectus,
interest income has been estimated at 5% of net assets.    


                              POTENTIAL ADVANTAGES
                              --------------------

     Although an investment in PB III is highly speculative and involves a high
degree of risk, an investment will offer the following potential advantages.
    
Professional Management.  Studies have shown that the vast majority of
- -----------------------                                               
individual investors lose money in the futures market.  However, other studies
have shown that a majority of professionally managed futures programs realize
annual net gains for their customers over the long term.     

                                      40

<PAGE>
 
    
     
     Asset Allocation Support.  Studies have also shown that including a
     ------------------------                                           
diversified mix of professionally managed futures programs in an investment
portfolio reduces volatility while enhancing the possibility of returns.
    
     Low Correlation with Stock and Bond Markets.  Quiet Systems Limited's
     -------------------------------------------                          
trading program has a low correlation to the stock and bond markets.  An
investment in PB III is therefore one way to attempt to obtain some 
diversification from those markets.    
    
     Vacation Awards.  An investor meeting the applicable qualification
     ---------------                                                   
requirements may receive a vacation award from the general partner, as described
in  "Vacation Award" below.     
    
     Lower Initial Investment Requirements.  The general minimum new account
     -------------------------------------                                  
size for Quiet Systems Limited's trading program is $625,000.  You can
participate in the trading program through PB III with only a minimum initial
investment of $5,000.  An investment in PB III therefore gives you the ability
to participate in a trading program most persons cannot afford to invest in
alone.     
    
     Limited Liability.  Unlike an individual who invests directly in futures, a
     -----------------                                                          
limited partner who does not participate in the control of PB III's business
generally cannot lose more than:     
    
     a.   the amount of the limited partner's capital contribution,     
    
     b.   the limited partner's share of undistributed profits, if any, 
          and,     
    
     c.   under limited circumstances, some amounts received as distributions or
          upon liquidation of units.     
    
The potential liability of a limited partner is discussed in more detail at "The
Limited Partnership Agreement--Nature of PB III; Liability of Limited Partners"
below.     
    
     Lower Time Commitment.  Trading in futures is a complicated process
     ---------------------                                              
involving a substantial time commitment and knowledge of the numerous factors
affecting the futures  markets.  An investment in PB III gives you the ability
to participate in those markets without such a substantial time commitment.     
    
     Gain Market Understanding.  An investment in PB III may also, however, be a
     -------------------------                                                  
way for you to gain a useful understanding of the futures markets by studying
the way Quiet Systems Limited trades and the various reports PB III will provide
to you.     
    
     No Load.  No front-end or back-end fees are charged by PB III.  This allows
     -------                                                                    
more of your money to remain available for investment through PB III.     

                                      41

<PAGE>
 
    
     Administrative Convenience.  PB III is structured to provide you with
     --------------------------                                           
certain services designed to alleviate the administrative details involved in
engaging directly in futures  trading, including providing monthly and annual
financial reports and all tax information about PB III which is necessary for
you to complete your federal income tax returns.     


                                USE OF PROCEEDS
                                ---------------
    
     The funds received from subscribers will be deposited and held in a
separate escrow account at First American Bank, Fort Dodge, Iowa, until $500,000
of units have been sold.   PB III therefore cannot start trading until at least
$500,000 of units have been sold.  Any contributions which are accepted by PB
III after funds have been released from escrow will be immediately available for
use in its business.     
    
     Once released from escrow, approximately 80% of PB III's funds will
generally be maintained in PB III's trading account with First Options of
Chicago, Inc.  Those funds will be available for trading in Quiet Systems
Limited's trading program.  The general partner estimates that from between
approximately 5% to 25% of those funds will normally be committed as margin for
its open positions, but the amount of funds committed as margin will greatly
exceed those percentages at times.  PB III's remaining funds will be held in
bank checking and interest bearing accounts for PB III's use and benefit.     
    
     PB III's trading account funds which are not committed as margin may be
invested in various interest bearing instruments or accounts.  Those instruments
and accounts include certificates of deposit, money market funds, treasury
bills, sweep accounts, money market funds or other similar liquid 
investments.     
    
     All interest and other earnings earned on PB III's funds will be paid to PB
III and not to the broker or other custodian having custody of the funds.     
    
     PB III will not have significant assets or properties other than PB III's
trading account with First Options of Chicago, Inc. and the other types of
accounts described in this section.  PB III's account with First Options of
Chicago, Inc. and some of the other accounts in which PB III's funds will be
deposited and held  are not federally insured or guaranteed.  PB III is subject
to the failure of the entities holding those funds, as noted at "Principal Risk
Factors--PB III Could Lose Assets or Have Its Trading Disrupted Due to the
Failure of Exchanges or Brokers" above.

     The types of interests PB III will trade in are discussed at "Investment
Program" below.     

    
     

     Neither PB III nor any of its affiliates are doing business with the
government of Cuba or with any person or affiliate located in Cuba.


                               INVESTMENT PROGRAM
                               ------------------
    
     The following description of Quiet Systems Limited's trading program is not
intended to be exhaustive since most of the trading methods, systems and
strategies utilized in the trading program are proprietary and confidential
information of Quiet Systems Limited.  If they were disclosed, it would cause
material harm to Quiet Systems Limited's business.  It is also very difficult to
explain the trading program in a helpful way in this prospectus since it is
based on various complex mathematical, statistical and other theories and
analyses.     
    
     There are numerous trading methods, systems and strategies utilized in
futures trading.  The following discussion only addresses those methods, systems
and strategies utilized in Quiet Systems Limited's trading program, and you will
therefore not be able to compare them with trading methods, systems and
strategies that are utilized by other trading advisors or trading managers.     

    
     

                                       43
<PAGE>
 
    
     

    
     Quiet Systems Limited's trading program in which PB III's account will be
traded is called the "Forex Index Program" by Quiet Systems Limited.  It is a
technical trading program that is based upon computer software.  It is a
systematic, trend following trading approach that utilizes multiple moving
averages to determine what trades should be made.  Trading in the Forex Index
Program is currently limited to eight different currency pairs, which are
discussed below.     
    
     The Forex Index Program has a high correlation with the Barclay Currency
Traders Index, and is intended to be leveraged so that it has similar
return/risk parameters to the currency trading managers followed by the Barclay
Currency Traders Index.  The Barclay Currency Traders Index is an index of
trading advisors tracked by Barclay's managed futures reports.  The Forex Index
Program does not, however, attempt to include all currency pairs or currency
programs.     

     The Forex Index Program is not correlated with traditional debt and equity
investments.
    
     A determination will be made every day whether to be long or short the
currency pairs.  The information that is most important in making this decision
is the deviation of price from the moving averages.  Trades will be determined
at a particular time during each day, and entered at a specified time on that
day.  It is contemplated that a long or short position will always be held in
each currency pair.     
    
     The currency pairs traded in the Forex Index Program will currently be
those that make up approximately 68% of the total global currency volume as set
forth in the 1995 Bank of International Settlements foreign exchange survey.
Those currency pairs are as follows:     
    
     .    U.S. Dollar/Japanese Yen;    
     .    British Pound/Japanese Yen;    
     .    Euro/Japanese Yen;
     .    Euro/Swiss Franc;
     .    U.S. Dollar/Euro;  
     .    U.S. Dollar/Swiss Franc;        

                                      44
<PAGE>
 
    
     .    U.S. Dollar/Canadian Dollar; and    
     .    U.S. Dollar/British Pound.      

    
     

    
     The Forex Index Program utilizes a static allocation among the currency
pairs being traded. The allocation is generally based upon world trade flow as
set forth in the 1995 survey referred to above, with netted out moving 
averages.     
    
     The choice of the currency pairs and the allocation among those pairs is
intended to try to cause the Forex Index Program to be weighted similar to
global trading flow patterns in the currency pairs.     
    
     The currency pairs and the allocation among the currency pairs may be
changed by Quiet Systems Limited at any time.  One reason Quiet Systems Limited
might make a change would be to maintain correlation with global trade flows in
the currency pairs.     
    
     Quiet Systems Limited contemplates that from approximately 5% to 25% of an
account traded in the Forex Index Program will generally be committed as margin.
The percentage of an account committed as margin may, however, substantially
exceed those percentages at times.     
    
     No stops are utilized in the Forex Index Program.  Stops are procedures
that are designed to automatically close out a position if a certain amount has
been lost on that position.     
    
     Trading in the Forex Index Program will mostly be through futures contracts
on United States and foreign exchanges. Trading may someday also be done in
the interbank forward markets.    
    
     Quiet Systems Limited does not contemplate that it will ever exercise
subjective discretion in determining any trades made in the Forex Index 
Program.     

                                      45

     All of Quiet Systems Limited's trading methods, systems and strategies may
be modified and adjusted at any time, in the sole discretion of Quiet Systems
Limited. If changes are made, the prior performance of Quiet Systems Limited
will not necessarily reflect the potential future performance of the trading
program.     
    
     You should also review "The CTA--Quiet Systems Limited" and "Performance
Records of Quiet Systems Limited" below for a further discussion of Quiet
Systems Limited's experience and its trading programs.     
    
     
    
     Various agreements and documents were required to be executed by PB III in
order to be able to participate in the trading program and to establish and
maintain PB III's trading account with First Options of Chicago, Inc. Those
agreements are discussed at "Conflicts of Interest--Agreements Required by Quiet
Systems Limited" and "Agreement with Frischmeyer Trading Corporation" above and
"Futures Commission Merchant" below.

                              THE GENERAL PARTNER
                              -------------------

    
     Background of the General Partner.  The general partner and commodity pool
     ---------------------------------                                         
operator of PB III is Portfolio Boost, L.L.C. The general partner will manage
the business of PB III. The general partner may retain third parties to provide
services to PB III, and other parties will be retained to provide accounting,
auditing, legal and other professional services.     
    
     The following paragraphs discuss the business background of the general
partner and of its principals for at least the five years preceding the date of
this prospectus.     
    
     The General Partner, Portfolio Boost, L.L.C.     
     --------------------------------------------
    
     The general partner is an Iowa limited liability company that was organized
in May of 1998. Its principal office is at 4320 Winfield Road, Suite 320,
Warrenville, Illinois 60555, and its telephone number is 1-877-RRRATIO. The
general partner is registered as a commodity pool operator with the Commodity
Futures Trading Commission, and is also a member of the National Futures
Association.     
    
     The general partner was organized for the purpose of serving as the general
partner of PB III and of Portfolio Boost I, L.P., Portfolio Boost II, L.P.,
Portfolio Boost MJF, L.P. and Corn Belt Commodities Round Trip Limited
Partnership. Those other entities are Iowa limited partnerships formed to
operate as commodity pools. The general partner may also serve as the commodity
pool operator for other new or existing pools in the future.     
    
     The trading accounts of Portfolio Boost I, L.P. and Portfolio Boost II,
L.P. will be traded in the 2 other trading programs offered by Quiet Systems
Limited as of the date of this prospectus. A brief discussion of those trading
programs is set forth in "Performance     

                                      47
<PAGE>
 
    
Records of Quiet Systems Limited" below. Portfolio Boost I, L.P. was formed in
May, 1998, and Portfolio Boost II, L.P. was formed in June of 1998, and neither
had accepted any capital contributions or had commenced trading as of the date
of this prospectus.

the trading programs of Michael J. Frischmeyer. Portfolio Boost MJF, L.P. was
formed in June of 1998, and had not accepted any capital contributions or
commenced trading as of the date of this prospectus. The general partner has not
decided when, if ever, it will offer Portfolio Boost MJF, L.P. to the 
public.     

     No offering of any units of limited partnership interest in Portfolio Boost
I, L.P., Portfolio Boost II, L.P. or Portfolio Boost MJF, L.P. is being made

of an Iowa limited partnership known as Corn Belt Commodities Round Trip Limited
Partnership ("CBC-RT"). CBC-RT has been trading since late 1994. CBC-RT utilizes

other broker-dealer activities.     
    
     Mr. Raun will participate in this offering pursuant to his registration
with Vacation Investors, Inc.  Mr. Raun also provides general brokerage services
to various persons and entities in that capacity.

     Members of the General Partner.     
     ------------------------------ 
    
     The general partner is an Iowa limited liability company that has two
different classes of members. One class of members holds voting units, and the
other class of members holds nonvoting units. As indicated above, all of the
voting units are held by Vacation Partners, Inc. Vacation Partners, Inc. is an
Iowa corporation that is wholly owned by Mr. Raun. Vacation Partners, Inc. was
incorporated in April, 1998, and was formed for the purpose of holding the

any business.     
    
     The nonvoting units of the general partner are owned by Dr. Mark and
Rebecca Westberg, Dr. Craig and Elizabeth Rowles, and Dr. Alan and Dorothy Raun,
with each couple as joint tenants. The nonvoting members do not have the right
to participate in or control the day-to-day operation of the general partner's
business, except only in certain limited circumstances specified in the
operating agreement of the general partner. Even if any of those circumstances
occur, however, it is contemplated that Mr. Raun will continue to serve as the
sole officer of the general partner and will make all operational decisions
regarding the general partner's services to PB III. No discussion of the
business background of the nonvoting members is included in this 
prospectus.    
    
     Performance Records of the General Partner.  PB III had not started trading
     ------------------------------------------                                 
as of the date of this prospectus, so this prospectus does not contain any
actual performance information for PB III. The general partner also serves as
the pool operator for CBC-RT. CBC-RT had commenced trading as of the date of
this prospectus, and certain performance records regarding CBC-RT are included
in "Performance Records of the General Partner" below, beginning on page 
56.

     ------------------------------------------------------------------      
general partner and its members may trade commodities and other interests for
their own accounts.  The records of any such trading and any written policies
related to such trading will not be made available to limited partners.     
                             ---

the general partner may purchase units, but no nonvoting members had acquired
any units as of the date of this prospectus. The purchase of units by the
general partner, Mr. Raun or the nonvoting members may create conflicts of
interest. See "Principal Risk Factors--The Purchase of Units by the General
          ---
Partner or Mr. Raun Will Create Conflicts of Interest for Them" above.     
    
     Compensation of the General Partner.  The compensation payable to the
     -----------------------------------

                         THE CTA--QUIET SYSTEMS LIMITED
                         ------------------------------
    
     Business Background.  Quiet Systems Limited is a corporation that was
     -------------------                                                  
organized under the laws of the Cayman Islands in March of 1998.  Quiet Systems
Limited was registered as a commodity trading advisor with the Commodity Futures
Trading Commission and became a member of the National Futures Association in
August, 1998.  Quiet Systems Limited is not registered in any capacity with any
authorities from any foreign country or jurisdiction.     
    
     The business of Quiet Systems Limited will be the trading of accounts under

*    Rate of Return is computed by dividing net performance by beginning net
     asset value for the period. For those months when additions or withdrawals
     exceed ten percent of beginning net assets, the Time-Weighting of Additions
     and Withdrawals method is used to compute rates of return.

     regulations to mean losses experienced by a pool or account over the
     specified period.

     The above performance capsule has been included in this prospectus in order
to comply with certain regulations of the Commodity Futures Trading Commission.
As indicated above, Frischmeyer Trading Corporation will not exercise any
discretion regarding PB III's trades. In addition, Frischmeyer Trading
Corporation's trading program is materially different from Quiet Systems
Limited's trading program. Given this, you should not assume that the
performance of Frischmeyer Trading Corporation's trading program will be
indicative of or similar to PB III's or Quiet Systems Limited's performance.    


                  PERFORMANCE RECORDS OF THE GENERAL PARTNER
                  ------------------------------------------
    
     PB III HAS NOT COMMENCED TRADING AND DOES NOT HAVE ANY PERFORMANCE HISTORY.
This prospectus therefore does not contain any actual performance records or
performance information for PB III.     
    
     Some supplemental performance information is, however, attached to this
prospectus as Appendix 1. The supplemental performance information presented in
Appendix 1 is hypothetical performance information. The footnotes and
assumptions following the table in Appendix 1 describe the supplemental
performance information. You should also carefully review the disclosures on the
                             ------                                             
cover page to Appendix 1 regarding the many limitations inherent in hypothetical
performance information.     
    
     The regulations of the Commodity Futures Trading Commission require that
the disclosure document of a pool operator include certain performance
information for each pool operated by the pool operator. As of the date of this
prospectus, the general partner was also serving as the pool operator for
Portfolio Boost I, L.P., Portfolio Boost II, L.P., Portfolio Boost MJF, L.P. and
CBC-RT. Those pools are briefly described in "The General Partner" above.
Portfolio Boost I, L.P., Portfolio Boost II, L.P., and Portfolio Boost MJF, L.P.
had not commenced trading as of the date of this prospectus, so no performance
records for any of those pools were available at that time.    
                                      56
<PAGE>
 
    
     CBC-RT began trading in December, 1994, and some performance and other
information regarding CBC-RT is set forth below.  CBC-RT has a different trading
advisor that utilizes trading methods which are materially different from the
trading methods utilized in Quiet Systems Limited's trading program.   CBC-RT
also pays different fees than PB III.  The performance information for CBC-RT
therefore should not be relied upon as any indication of PB III's potential
performance.  The general partner temporarily suspended trading by CBC-RT on
April 30, 1998, because the trading of CBC-RT's account by its trading advisor
had failed to generate any profits since 1995.  CBC-RT did recommence trading,
however, on July 1, 1998.  The trading advisor for CBC-RT is Michael J.
Frischmeyer.     
    
     CBC-RT is a single advisor pool that does not have a guarantee feature. The
following capsule shows the annual past performance of CBC-RT since the
inception of trading by CBC-RT (in December, 1994) and year-to-date (through
November 30, 1998). PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE
RESULTS.

**    "Draw-Down" is defined by applicable Commodity Futures Trading Commission
      regulations to mean losses experienced by a pool or account over the
      specified period.     
    
***   "Net Asset Value" is defined by applicable Commodity Futures Trading
      Commission regulations to mean total assets minus total liabilities,
      determined on an accrual basis of accounting in accordance with generally
      accepted accounting principles, with each position in a commodity interest
      accounted for at fair market value.     
    
****  "Worst Peak-to-Valley Draw-Down" is defined by applicable Commodity
      Futures Trading Commission regulations to mean the greatest cumulative
      percentage decline in month-end net asset value due to losses sustained by
      a pool, account or trading program during any period in which the initial
      month-end net asset value is not equaled or exceeded by a subsequent 
      month-end net asset value.    
    
***** The general partner temporarily suspended trading by CBC-RT on April 30,
      1998, given the failure of CBC-RT's trading to generate any profits since
      1995. The general partner reinstituted trading on July 1, 1998.     
    
      CBC-RT pays the general partner a monthly incentive fee equal to 15% of
the new trading profits of CBC-RT, if any, for each month. CBC-RT also pays the
general partner a monthly management fee of one-third of one percent of CBC-RT's
net assets as of the close of business on the last business day of each month.
CBC-RT's trading advisor receives a portion of the brokerage commissions payable
on trades made by CBC-RT. CBC-RT is also responsible for all brokerage
commissions, exchange and National Futures Association fees and other trading
costs and expenses. The range of commissions payable by CBC-RT as of the date of
this prospectus was between $40 and $64 per contract, with an average of
approximately $56. The other operating expenses of CBC-RT, such as legal and
accounting and auditing fees, are lower than the operating expenses of PB
III.    
    
     
    
      No performance records for the four limited partnerships for which Mr.
Raun serves as the general partner are included in this prospectus because:     
    
      .   they are not required under the Commodity Futures Trading Commission's
          regulations,     
    
      .   none of those limited partnerships utilize Quiet Systems Limited,     
    
      .   the trading advisor for the limited partnerships utilizes trading
          methods which are materially different from the trading methods
          utilized by Quiet Systems Limited, and     
    
      .   the limited partnerships pay different fees than PB III.     
    
     

                                      58
<PAGE>
 
    
Also, the performance records of CBC-RT are somewhat representative of the
performance of each of the limited partnerships during the period presented for
CBC-RT because the limited partnerships have the same general fee load as CBC-RT
and use the same trading advisor.     


                  PERFORMANCE RECORDS OF QUIET SYSTEMS LIMITED
                  --------------------------------------------

     NEITHER QUIET SYSTEMS LIMITED NOR ANY OF ITS TRADING PRINCIPALS HAVE
PREVIOUSLY DIRECTED ANY ACCOUNTS.
    
     As of the date of this prospectus, Quiet Systems Limited was offering three
trading programs.  All of the trading programs are based on software purchased
from Mr. Gogerty.  Quiet Systems Limited refers to the programs as:     
    
     .  the Forex Index Program (which is the trading program used by PB III),
     .  the Diversified Program, and
     .  the Financial Program.     
    
The accounts of Portfolio Boost I, L.P. and Portfolio Boost II, L.P. will be
traded in the latter 2 programs.  No performance records of Quiet Systems
Limited are included in this prospectus since Quiet Systems Limited had not
directed trading for any accounts under any of its trading programs as of the
date of this prospectus.     
    
     
    


     Financial Program of Quiet Systems Limited.
     ------------------------------------------ 

     Quiet Systems Limited's Financial Program is a systematic, trend following
trading approach which utilizes multiple moving averages and a breakout system
to determine what trades should be made.     

                                       59

<PAGE>
 

    
The Financial Program is not correlated with traditional debt and equity
investments.    
    
     Trading in the Financial Program will be limited to various financial
instruments, currencies, indices and interest rate contracts.  The particular
financial instruments, currencies, indices and interest rate contracts that are
traded may be changed by Quiet Systems Limited at any time.     
    
     The allocation among the financial instruments, currencies, indices and
interest rate contracts being traded is determined pursuant to a mathematical
optimizer  program.  The allocation may be changed by Quiet Systems Limited at
any time.     
    
     Quiet Systems Limited contemplates that from between approximately 5% to
25% of an account traded in the Financial Program will generally be committed as

     Trading in the Financial Program will mostly be through futures contracts
on United States and foreign exchanges.  Trading may some day also be through
the interbank forward markets.

     Diversified Program of Quiet Systems Limited.
     -------------------------------------------- 

     Quiet Systems Limited's Diversified Program is a systematic, trend
following trading approach which utilizes multiple moving averages and a
breakout system to determine what trades should be made.  The Diversified
Program is not correlated with traditional debt and equity investments.     
    
     The Diversified Program is currently programmed to trade in the following
types of interests:     
    
     .  grains,     
    
     .  energies,     

                                       60

     .  metals,     
    
     .  currencies,     
    
     .  interest rates, and     
    
     .  other financial interests.     
    
The types of interests traded may be changed by Quiet Systems Limited at any
time.

     The allocation among the types of interests being traded is determined
pursuant to a mathematical optimizer program.  The allocation  may be changed by
Quiet Systems Limited at any time.     
    
     Quiet Systems Limited contemplates that from between approximately 5% to
25% of an account traded in the Diversified Program will generally be committed
as margin for trading.  No stops are utilized in the Diversified Program.     
    
     Trading in the Diversified Program will mostly be through futures
contracts on United States and foreign exchanges.  Trading may some day also be
through the interbank forward markets.

                          FUTURES COMMISSION MERCHANT
                          ---------------------------
    
     First Options of Chicago, Inc. has been selected as the initial futures 
commission merchant for PB III.  First Options has an agreement with LBS 
Limited Partnership whereby LBS will execute all of the trades of PB III, but 
will give up all of the trades to First Options for clearing.     
    
     First Options is a Chicago-based commodities brokerage firm whose principal
business is the clearing of futures, options and securities for its customers.
First Options is registered as a futures commission merchant with the Commodity
Futures Trading Commission, and is also registered as a securities broker-
dealer.  First Options is also a member of the National Futures Association and
the National Association of Securities Dealers, as well as a member of major
futures and securities exchanges      

                                       61
<PAGE>
 
    
in the United States.  First Options is also a clearing member of the Chicago
Board of Trade and the Chicago Mercantile Exchange and has established
facilities to handle business on all other exchanges on which PB III currently
contemplates trading.     
    
     First Options' services are limited solely to providing clearing services.
First Options does not have any responsibility to, and will not, supervise the
actions of Quiet Systems Limited, PB III or the general partner.  First Options'
agreement to clear trades for PB III does not constitute an endorsement or
recommendation by First Options of PB III, the general partner, Frischmeyer
Trading Corporation, Quiet Systems Limited, or Quiet Systems Limited's trading
program.  The same is true for LBS.     
    
     PB III's agreements with First Options may be terminated by PB III at any
time.  The only written agreements that have been entered into between PB III
and First Options are First Options' standard customer account agreements.     
    
     LBS is registered as a non-clearing futures commission merchant with the
Commodity Futures Trading Commission.     

     PB III has not retained any introducing broker, and does not intend to do
so.
    
     As a futures commission merchant and securities broker-dealer, First
Options is involved in litigation and regulatory actions on an on-going basis.
The general partner does not, however, believe that there have been any material
administrative, civil or criminal actions against First Options during the 5
years before the date of this prospectus, except for the matter described in the
following paragraphs.     
    
     
    
     In January of 1994, a customer of First Options was awarded $886,000 in an
NASD arbitration proceeding which had been instituted by the customer against
First Options.  The amount which had been sought by the customer was $5,800,000.
The customer's claims against First Options related to margin calls, alleged
misrepresentations and other clearing and breach of contract disputes.     

                                       62
<PAGE>
 
    
     Although the above matter is material, the general partner does not believe
that it is indicative of First Options' standard business practices.  The
general partner's belief is based upon First Options having served as the
futures commission merchant for some of the limited partnerships for which Mr.
Raun serves as the general partner since late 1992, and the general partner's
review of public records supplied by the National Futures Association and the
National Association of Securities Dealers regarding claims and actions brought
against First Options.  Although those records do reveal that various other
actions or claims have been brought against First Options, the general partner
does not believe the other actions or claims are material in number or of a
material nature.     
    
     As of the date of this prospectus, the round turn commission payable by  PB
III for trades cleared by First Options was fixed at $11.00.  The commissions
payable by PB III are divided between First Options and LBS as discussed at
"Description of Charges to PB III--Allocation of Commissions" above.  The
brokerage commissions are subject to change at any time.     


                   TRANSFERABILITY AND LIQUIDATION OF UNITS
                   ----------------------------------------
    
     The following is a summary of the conditions that must be met in order to
transfer units and to liquidate units.  You should read the limited partnership
agreement for complete details of the conditions.  See, in particular, Articles
                                                   ---                         
IV and VIII of the limited partnership agreement.     
    
     Transfers of Units. Units cannot be assigned or transferred until the
     -------------------
assignor of the units and the assignee have delivered an assignment and
assumption agreement to the general partner, and the general partner gives its
written consent to the assignment. The general partner will generally give its
consent if the assignment or transfer will not violate any securities, tax or
other laws or rules and will not affect the tax status or treatment of PB III.
The general partner may, however, also withhold its consent if either the
assignor of the units or the assignee will hold units that represent less than
the $5,000 minimum initial investment in PB III. The general partner may also
require the assignee of the units to pay all expenses incurred in connection
with the assignment, such as attorneys' fees. Any assignment of a unit not made
in compliance with the limited partnership agreement is invalid.    

                                      63
<PAGE>

 
    
     The transfer or assignment of a unit will not relieve the assignor of any
obligations already owed to PB III.     
    
     The effective date of an assignment of a unit will generally be the first
business day of the month which follows the date on which the general partner
has given its consent to the assignment.     
    
     An assignee of a unit only has the right to receive the share of the
profits, losses, distributions and returns of capital that apply to the assigned
unit.  The assignee cannot vote the unit unless and until the assignee becomes a
substituted limited partner, as discussed in the following paragraph.     
    
     

                                       64
<PAGE>
 
    
     The assignor of a unit can direct that the assignee will be a substituted
limited partner in PB III.  The consent of the general partner or the limited
partners is not necessary, and the assignee of a unit will automatically become
a substituted limited partner unless the assignor of the unit states otherwise.
In that case, the assignor can still choose to make the assignee a substituted
limited partner at a later time.  An assignee of a unit may also become a
substituted limited partner without the approval of the assignor, if all of the
other limited partners vote to allow the assignee to become a substituted
limited partner.  An assignee of a unit who has become a substituted limited
partner has all of the rights of a limited partner with respect to the unit,
including the right to vote.     
    
     
     
     Liquidation of Units. Units can generally be liquidated on the first 
     --------------------- 
business day of any month. In order to do so, however, a limited partner must 
give the general partner prior written notice. The general partner may require 
that the liquidation notice be received by the general partner 60 days in 
advance of the desired liquidation date.    
    
     The liquidation price per unit will be the net asset value per unit as of
the opening of trading on the first business day of the applicable month. Net
asset value per unit means the net assets of PB III at that time divided by the
aggregate number of outstanding units at that time.  Net assets means total
assets minus total liabilities, determined in accordance with generally accepted
accounting principles, except that all organizational and offering expenses
incurred by PB III prior to the effective date of its initial registration
statement filed with the Securities and Exchange Commission will be amortized
over a period of 5 years.  The amortization of the organizational and offering
expenses is required under the limited partnership agreement, and is intended to
spread out those costs so limited partners are treated more fairly.     
    
     The liquidation price will not be fixed until the first business day of the
applicable month.  In other words, limited partners are subject to any change in
the net asset value per unit occurring between the date of their request for
liquidation and the effective date of the liquidation.  That delay may be a
period of up to 60 days.  The net asset value per unit could change
significantly, for better or worse, during that period, given the volatile
nature of futures    

                                       65

trading.     
    
     The general partner will not assess any fees or charges for liquidations.
The general partner may change this policy in the future.     
    
     
    
     
    
     
    
     A limited partner will be notified within 10 days after the first business
day of the applicable month of whether the limited partner's units have been
liquidated. Payment for liquidated units will generally be made within 30 days
after the first business day of the applicable month.    
    
     The limited partnership agreement authorizes the general partner to refuse
to liquidate units if the number of requested liquidations may be detrimental to
the tax status or treatment of PB III.  The general partner may also refuse a
liquidation request if the remaining capital account of the limited partner will
be less than the $5,000 minimum initial investment amount.  The limited
partnership agreement also authorizes the general partner to     

                                       66
<PAGE>
 
    
temporarily suspend all liquidations and to delay payment for liquidations under
special circumstances. Some examples of special circumstances for this purpose
include:     
    
     .    the inability to generate sufficient cash due to market 
          illiquidity,     
    
     .    where the cash can only be generated by sustaining significant losses,
          and     
    
     .    defaults or delays in payments due PB III from brokers or other
          persons.     
    
All units will remain at risk in the business of PB III in any of these
circumstances.     
    
     A limited partner therefore may not always be able to liquidate his or her
units.     
    
     The general partner will give each limited partner written notice in the
event there is a 50% decline in the net asset value per unit over any 1 year
period. The written notice will be given within 7 days of the date the 50%
drawdown has occurred.  If this occurs, PB III will temporarily suspend trading
for a period of 30 calendar days, beginning on the date of the general partner's
notice.  The limited partners will be able to request liquidation of their units
during that 30 day period.  A liquidation in this event will be effective as of
the opening of trading on the business day after the general partner receives
the limited partner's liquidation request.  Any requests may, however, be
denied, suspended or delayed for the same reasons described in the preceding
paragraphs.     
    
     The general partner will also give each limited partner notice at least 30
days before the general partner makes any material change related to brokerage
commissions.   The limited partners will be able to request liquidation of their
units during that 30 day period.     
    
     
    
     
    
     Requests for liquidation should be transmitted to the general partner at
the main business office of PB III set forth on page 1 of this prospectus.     
    
     

                                       67
<PAGE>
 
    
     
    
     The general partner may require IRA or retirement plan or employee benefit
plan accounts to liquidate their units if the liquidation will help PB III, the
general partner or any limited partner avoid being subject to or violating any
of the provisions of  the Employee Retirement Income Security Act of 1974.
The general partner may make distributions to IRA or retirement plan or employee
benefit accounts for the same reason.     
    
     
    
     A limited partner who has received the return of any part of the limited
partner's capital contribution through the liquidation of units or through
distributions to the limited partner can be required to return that amount to PB
III for a period of up to one year after the return, if needed to pay creditors
who extended credit to PB III during the time the contribution was held by PB
III.  If the return violated the limited partnership agreement or the Iowa
Uniform Limited Partnership Act, however, the limited partner can be required to
return that amount to PB III for a period of up to 6 years after the 
return.

                              THE FUTURES MARKETS     
                              -------------------
    
     This section is intended to give you an overview of the futures markets and
futures trading in general.  It is not a complete discussion of the futures
markets or futures trading.     
    
     Markets.  Futures contracts are contracts usually made on an exchange which
     -------                                                                    
provide for the future delivery of specified quantities and grades of various
commodities, currencies, financial instruments or other interests.   The size
and term of futures contracts are identical and are not subject to negotiation
between the buyer and seller.  A futures contract is satisfied either by taking
or making physical delivery of an approved grade of the interest being traded or
by making an offsetting sale or purchase of an equivalent but opposite futures
contract on the same exchange prior to the designated date of delivery.  For
example,  the contractual obligation arising from the sale of one contract of
December wheat may be satisfied at any time before delivery of the wheat is
required by the purchase of one contract of December wheat on the same exchange.
In that example, the difference between the price at which the futures contract
was sold and the price paid for the offsetting purchase, after allowance for
brokerage commissions and other transaction costs and expenses, represents the
profit or loss to the trader.     
    
     A trader who purchases a futures contract is obligated to take delivery of
the underlying interest, and is sometimes said to be "long" in the futures
market. A trader who sells a futures contract is obligated to make delivery of
the underlying interest, and is sometimes said to be "short" in the futures
market.  A trader who is long the market believes the market in the interest
will go up.  A trader who is short the market believes the market in the
interest will go down.     
    
     Before a trader closes out the long or short position by an offsetting sale
or purchase, the outstanding contract is sometimes referred to as an "open
trade" or "open position."  The aggregate amount of open positions held by
traders in a particular contract is sometimes referred to as the "open interest"
in the contract.     

                                      69

     Some of the agricultural commodities for which there are futures contracts
are corn, wheat, soybeans, soybean oil, soybean meal, live cattle, live hogs,
pork bellies, iced broilers, sugar, cocoa and cotton.  Some of the
nonagricultural commodities for which there are futures contracts are copper,
silver, gold, lumber, currencies, United States Treasury bills, commercial paper
and mortgage-backed securities.  As discussed elsewhere, however, PB III's
trading will be limited to contracts in the 8 currency pairs traded in Quiet
Systems Limited's trading program.     
    
     The two broad classifications of persons who trade in futures contracts are
"hedgers" and "speculators."  Commercial interests (such as farmers) which
market or process commodities and financial     

                                      70
<PAGE>
 
    
institutions that market or deal in interest rate sensitive instruments, foreign
currencies and stock portfolios may use the futures markets primarily for
hedging. Hedging is a protective procedure designed to minimize losses which may
occur because of price fluctuations occurring in the underlying commodity. For
example, a farmer may hedge against price fluctuations between the day the
farmer plants the farmer's crop and the day the crop is ready for delivery. If
the futures price quoted for the anticipated date of delivery will cover the
farmer's costs and leave a profit deemed adequate, the farmer can sell the
future "short" (i.e., become obligated to make delivery), and deliver the crop
                ----        
grown on the delivery date under the futures contract. If the farmer does not
want to make delivery under the futures contract, the farmer can sell the crop
in the local market and close out the futures position by purchasing a futures
contract.     
    
     The usual objective of the hedger is to protect the profit which the hedger
expects to earn from the hedger's general business operations, rather than to
profit from the futures trading.     
    
     The speculator's objective, on the other hand, is to make a profit from
price fluctuations in futures contracts.  Speculators rarely make or take
delivery of the physical commodity, but rather close out their futures positions
by entering into offsetting purchases or sales of futures contracts.  Since the
speculator may take either a long or short position in the market, it is
possible to make profits or incur losses regardless of whether prices are going
up or down.     
    
     All trades made by PB III will be speculative, and not for hedging
purposes.  There are always two parties to a futures contract.  If one party to
the contract experiences a gain on the contract, the other party experiences an
equal amount of loss.  Accordingly, only 50% of futures contracts can experience
gain at any one time, without reference to commissions and other costs of
trading which will reduce and could eliminate the gain.     
    
     Regulation. Exchanges provide centralized market facilities for trading in
     ----------                                                                
futures contracts on various commodities, currencies and other interests.  Among
the principal exchanges in the United States are the Chicago Board of Trade, the
Chicago Mercantile Exchange and the Commodity Exchange, Inc.     

                                      71
<PAGE>
 
    
     Each of the exchanges in the United States has an associated
"clearinghouse."  Once trades between members of an exchange have been
confirmed, the clearinghouse becomes substituted for each buyer and each seller
of contracts traded on the exchange and, in effect, becomes the other party to
each trader's open position. The parties to the trade then generally look only
to the clearinghouse for performance.     
    
     The clearinghouse generally establishes some sort of security or guarantee
fund to which all clearing members of the exchange must contribute.  This fund
is intended to act as an emergency buffer to enable the clearinghouse to attempt
to meet the obligations of an insolvent clearing member's contracts.
Clearinghouses also require margin deposits and continuously mark positions to
market to attempt to provide some assurance that their members will be able to
fulfill their contractual obligations. A central function of the clearinghouses
is to attempt to support the integrity of trades, and members effecting futures
transactions on an organized exchange generally do not need to worry about the
solvency of the other party to the trade. An exchange and clearinghouse system
is not, however, available when trading in forward contracts, as discussed at
"Principal Risk Factors--PB III May Trade in Forward Contracts That are Less
Regulated and Involve More Risks Than Trading on Exchanges" above.    
    
     Trading on non-United States exchanges involves other risks, some of which
arise from the fact that the Commodity Futures Trading Commission has no
authority to regulate trading on foreign exchanges. The risks to trading on
foreign exchanges are discussed at "Principal Risk Factors--PB III Will Trade on
Foreign Exchanges That are Less Regulated Than U.S. Markets and are Subject
to Risks That Don't Always Apply to U.S. Markets" above.     
    
     Trades made on an exchange are subject to the rules of that exchange.
Exchanges in the United States are given some latitude in promulgating rules and
regulations to control and regulate their members.  Examples of regulations by
exchanges include the establishment of initial margin levels, size of trading
units, contract specifications, speculative position limits and daily price
fluctuation limits.  The Commodity Futures Trading Commission reviews some of
those rules and can disapprove or require that they be amended or modified.     
    
     Exchanges in the United States are subject to regulation by the Commodity
Futures Trading Commission under the Commodity Exchange Act.   Under the
Commodity Exchange Act, the Commodity Futures Trading Commission is the
governmental agency having primary responsibility for the regulation of
exchanges and futures trading in the United States.  The general function of the
Commodity Futures Trading Commission is to implement the objectives of the
Commodity Exchange Act of preventing price manipulation and excessive
speculation and promoting orderly and efficient futures markets.     

                                      72
<PAGE>
 
    
     The Commodity Futures Trading Commission and the exchanges may take
extraordinary actions in the event of a market emergency, including, for
example, the retroactive implementation of speculative position limits or higher
margin requirements, the establishment of daily price limits and the suspension
of trading.  For example, some emergency actions were taken with respect to
certain stock index futures contracts following the extraordinary decline of
stock prices on October 19, 1987.  The excercise of emergency actions by the
Commodity Futures Trading Commission or the exchanges could have a detrimental
effect on PB III's trading performance.     
    
     The Commodity Futures Trading Commission has exclusive jurisdiction to
regulate the activities of commodity trading advisors and commodity pool
operators.     
    
     The general partner is registered as a commodity pool operator with the
Commodity Futures Trading Commission.  The Commodity Exchange Act requires a
registered commodity pool operator to make annual filings with the Commodity
Futures Trading Commission and authorizes the Commodity Futures Trading
Commission to require and to review the books and records of the commodity pool
operator.  The Commodity Exchange Act authorizes the Commodity Futures Trading
Commission to suspend the registration of a commodity pool operator in various
circumstances.     
    
     Quiet Systems Limited is registered as a commodity trading advisor with the
Commodity  Futures Trading Commission and the Commodity Exchange Act gives the
Commodity Futures Trading Commission similar authority with respect to the
activities of commodity trading advisors.     
    
     If the registration of the general partner as a commodity pool operator
were terminated or suspended, the general partner would be unable to manage the
business of PB III.  If the registration of Quiet Systems Limited as a commodity
trading advisor were terminated or suspended, Quiet Systems Limited would be
unable to provide trading advice and services to PB III.

     First Options of Chicago, Inc., PB III's futures commission merchant, is
also subject to regulation by the Commodity Futures Trading Commission. The
Commodity Exchange Act requires all futures commission merchants to meet and
maintain specified fitness and financial requirements, segregate customer funds
from proprietary funds, account separately for all customers' funds and
positions, and maintain specified books and records on customer transactions
which are open to inspection by the staff of the Commodity Futures Trading
Commission. The Commodity Exchange Act authorizes the Commodity Futures Trading
Commission to regulate trading by futures commissions merchants and their
officers and directors.     
    
     The National Futures Association was formed pursuant to authority in the
Commodity Exchange Act, and is registered with the Commodity Futures Trading
Commission as a registered futures association.  At the present time, the
National Futures Association is the only non-exchange self-regulatory
organization.  The National Futures Association promulgates rules governing the
conduct of various futures participants and disciplines those persons who do not
comply with those rules.  The National Futures Association also arbitrates
disputes between members and their customers and conducts fitness screening of
applicants for membership and audits of its existing members.  The Commodity
Futures Trading Commission has delegated to the National Futures Association
responsibility for the review of disclosure documents of commodity pool
operators offering private pools and of commodity trading advisors, and the
registration under the Commodity Exchange Act of commodity trading advisors,
commodity pool operators, futures commission merchants, introducing brokers and
their respective associated persons and floor brokers.  The general partner,
Quiet Systems Limited and First Options of Chicago, Inc. are members of the
National Futures Association.

     The regulations of the Commodity Futures Trading Commission and National
Futures Association prohibit any representation that registration or membership
with those entities indicates that the Commodity Futures Trading Commission or
the National Futures Association  has approved or endorsed the person or the
person's trading programs or objectives.  The registrations and memberships
described above must not be considered as constituting any such approval or
endorsement.  Also, no exchange has given or will give any such approval or
endorsement.     
    
     PB III is not registered under the Investment Company Act of 1940 and the
general partner and Quiet Systems Limited are not registered under the
Investment Advisors Act of 1940 or any similar state law. Any protective
measures provided by any of that legislation therefore is not available to
investors in the units.    
    
     Limited partners will have the right in some circumstances to institute
reparations proceedings under the Commodity Exchange Act, and the Commodity
Futures Trading Commission has adopted regulations about those proceedings.  The
regulations provide that any person may file a complaint for a reparations award
with the Commodity Futures Trading Commission for violation of the Commodity
Exchange Act against a floor broker, a futures commission merchant and its
associated persons, an introducing broker, a commodity trading advisor or a
commodity pool operator and their respective associated persons.  As discussed
at "Fiduciary Responsibility of the General Partner" above, however, it may be
difficult for limited partners to establish a violation of the Commodity
Exchange Act, and the limited partnership agreement may limit some of the legal
remedies otherwise available to the limited partners.     
    
     Most United States exchanges limit the amount of fluctuation in the prices
of futures contracts during a single trading day by regulations sometimes
referred to as "daily price fluctuation limits" or "daily limits." The daily
limits establish the maximum amount the price of a futures contract may vary
either up or down from the previous day's settlement price. Once the daily limit
has been reached, no trades may be made at a price beyond the limit. This
creates liquidity problems because positions in the interest can then be taken
or liquidated only if traders are willing to effect trades at or within the
limit. Because the daily limit regulations only govern price movement for a
particular trading day, the regulations do not limit losses. Futures prices have
occasionally moved the daily limit for several consecutive trading days
preventing prompt liquidation of futures positions on one side of the market,
and causing substantial losses for those days. Daily price limits can create
risks, as discussed in "Principal Risk Factors--Illiquid Markets Could Make it
Impossible to Realize Profits or Limit Losses" above.    
    
     The Commodity Futures Trading Commission and certain United States
exchanges have established limits on the maximum net long or net short position
which any person or group of persons may hold or control in particular futures
contracts. One of the purposes of these speculative position limits is to
attempt to prevent a "corner" on a market or undue influence on prices by any
single trader or group of traders. The Commodity Futures Trading     

                                       75
<PAGE>
 
    
Commission has jurisdiction to establish position limits, and the Commodity
Futures Trading Commission requires each United States exchange to submit
position limits for approval by the Commodity Futures Trading Commission. Some
exchanges or their clearinghouses also set limits on the total net positions
that may be held by a futures commission merchant, such as First Options of
Chicago, Inc. Position limits do not, however, generally apply to many currency
futures contracts, and no position limits are currently in effect in forward
contract trading. "Principal Risk Factors--PB III's Trading Could Be Adversely
Affected by Speculative Position Limits" above provides a discussion of the 
potential adverse effects to PB III if position limits are triggered by Quiet
Systems Limited's trading.    
    
     Margins.  Futures contracts are customarily bought and sold on initial
     -------                                                               
margins which range upward from less than 1% of the purchase price of the
contract being traded.  The initial margin is the minimum amount of funds which
must be deposited by the trader with the futures commission merchant in order to
establish open positions in futures contracts.  Because of these low margins,
price fluctuations occurring in futures markets may create profits and losses
which are greater, in relation to the amount invested, than are customary in
other forms of investment.  Leverage can also quickly lead to substantial
losses, however, as discussed at "Principal Risk Factors--The High Degree of
Leverage Used in Futures Trading Increases the Risk of Sudden, Major Losses"
above.    

     "Maintenance" margin is the amount (generally less than initial margin) to
which a trader's account may decline before the trader must deliver additional
margin.
    
     A margin deposit is like a cash performance bond because it is intended to
help assure the trader's performance of the futures contract the trader has
purchased or sold.     
    
     
    
     Margin amounts are set by the exchanges. Brokerage firms may require higher
margin amounts to attempt to obtain further protection for themselves.    
    
     Trading in forward contract markets does not currently require margin.     

                                       76
<PAGE>
 
    
     
    
     Margin requirements are computed each day by a trader's futures commission
merchant. When the market value of an open futures position changes to a point
where the margin on deposit does not satisfy maintenance margin requirements, a
margin call will be made by the trader's futures commission merchant. Margins
calls can occur frequently and the amount of a margin call can be significant.
If a margin call is not met, the futures commission merchant is required to
close out the trader's position.     
    
     

                          FEDERAL INCOME TAX ASPECTS
                          --------------------------
    
     General.  In the opinion of Nyemaster, Goode, Voigts, West, Hansell &
     -------                                                              
O'Brien, P.C., the following summary of the tax consequences to United States
taxpayers who are individuals is materially correct.  (This discussion assumes
that an investor is an individual, and not a corporation or other entity.  The
tax issues and analysis applicable to corporations or other entities may be
different than set forth in this discussion.)  Its opinion is filed as an
Exhibit to the Registration Statement of which this prospectus is a part.  The
opinion of Nyemaster, Goode, Voigts, West, Hansell & O'Brien, P.C. is its best
judgment of the law and published interpretations as of September 3, 1998.  The
opinion is not binding on the IRS or the courts.  PB III has not asked for a
ruling from the IRS with respect to any matter.     
    
     PB III Tax Status.  PB III will be taxed as a partnership and will not pay
     -----------------                                                         
federal income tax.  Based on the income expected to be earned by PB III, it
will not be taxed as a "publicly traded" partnership.     
     
     Taxation of Limited Partners on Profits or Losses.  Each limited partner
     -------------------------------------------------                       
must pay tax on his or her share of PB III's income and gains. Such share must
be included each year in a limited partner's taxable income whether or not the
limited partner has liquidated units or received any cash distributions. PB III
provides each limited partner with an annual schedule of his or her share of tax
items. PB III generally allocates these items equally to each unit.    

                                      77
<PAGE>
 
    
     Loss Deductions.  A limited partner may not deduct losses or deductions in
     ---------------                                                           
excess of his or her tax basis in his or her units as of year-end.  A limited
partner's tax basis in his or her units is the amount paid for such units
reduced by his or her share of any distributions, losses and deductions, and
increased by his or her share of income and profits.     
    
     Limited Deductibility for Certain Expenses.  Individual taxpayers are
     ------------------------------------------                           
subject to material limitations on their ability to deduct investment expenses
and other expenses of producing income.  The amount of such expenses subject to
the limitation should be small as a percentage of total income.  Individuals
cannot deduct investment expenses in calculating alternative minimum tax.     
    
     Mark-to-Market of Open Positions.  Section 1256 Contracts are futures,
     --------------------------------                                      
futures options traded on U.S. exchanges, certain foreign currency contracts and
stock index options. Certain of PB III's open positions will likely be Section
1256 Contracts. Section 1256 Contracts which remain open at the end of each year
are treated for tax purposes as if such positions had been sold and any gain or
loss recognized. The gain or loss on Section 1256 Contracts is characterized as
40% short-term capital gain or loss and 60% long-term capital gain or loss
regardless of how long any given position has been held. Non-U.S. exchange-
traded futures are non-Section 1256 Contracts. Gain or loss on non-Section 1256
Contracts will be recognized when sold by PB III and will be primarily short-
term gain or loss.    
    
     Section 988 Transaction.  A Section 988 Transaction is a forward contract,
     -----------------------                                                   
futures contract,  option or other similar financial instrument denominated in a
currency other than the dollar.  Section 988 Transaction gains or losses are
separately computed from other gains or losses and are treated as ordinary
income or loss rather than as capital gain.  An election can be made to apply
Section 1256 to any gain or loss attributable to a forward contract, futures
contract or option which is otherwise a capital asset in the hands of the
taxpayer and is not part of a straddle or hedge.     
    
     Tax on Capital Gains and Losses; Interest Income.  As described under
     ------------------------------------------------                     
"Mark-to-Market of Open Positions," PB III's trading, not including its cash
management which generates primarily ordinary income, generates 60% long-term
capital gains or losses and 40% short-term capital gains or losses from its
Section 1256 Contracts and primarily short-term capital gain or loss from its
non-Section 1256 Contracts.  Individuals pay tax on long-term capital gains,
other than gains on assets held for more than 1 year but less than 18 months, at
a maximum rate of 20%.  Short-term capital gains are subject to tax at the same
rates as ordinary income, with a maximum rate of 39.6% for individuals.     
    
     Individual taxpayers may deduct capital losses only to the extent of their
capital gains plus $3,000.  Accordingly, PB III could incur significant losses,
but a limited partner will still be required to pay taxes on his or her share of
PB III's interest income.     
    
     If an individual taxpayer incurs a net capital loss for a year, the
taxpayer may elect to carry back (up to three years) the portion of such loss
which consists of a net loss on Section 1256 Contracts.  A taxpayer may deduct
such losses only against net capital gain for a carry back year to the extent
that such gain includes gains on Section 1256 Contracts.  To the extent that a
taxpayer could not use such losses to offset gains on Section 1256 Contracts in
a carry back year, the taxpayer may carry forward those losses indefinitely as
losses on Section 1256 Contracts.

     Investment by Employee Benefit Plans and IRA's.  If you exercise
     ---------------------------------------------                  
discretionary authority or control over the management or disposition of an
employee benefit plan's plan assets or you render investment advice for a fee,
you are a plan fiduciary under the Employee Retirement Income Security Act of
1974 ("ERISA").  If you, as fiduciary, are considering investing plan assets in
PB III, keep in mind ERISA's applicable fiduciary standards, including:     
    
     . the definition of plan assets under Department of Labor regulations
(see below),     
    
     . whether the investment is subject to ERISA's diversification 
requirements,     
    
     . whether the investment is prudent and whether there will be a market for
sale or disposal of the units, and     
    
     . whether the investment is in accordance with the qualified plan's
governing documents.    
    
     An investment of IRA assets in PB III generally will not be subject to
ERISA's diversification and prudence requirements unless the IRA is treated as a
plan established or maintained by an employer, employee organization or 
both.     
    
     
    
     The Department of Labor's regulation defining "plan assets" generally
provides that when a plan makes an equity investment in another entity, the
underlying assets of that entity will be considered plan assets unless, for
purposes relevant here, equity participation by benefit plan investors is not
"significant."     

                                      79
<PAGE>
 
    
     
    
     Equity participation by benefit plan investors  becomes "significant" if
immediately after the most recent acquisition of any equity interest in the
entity, 25% or more of the value of equity interest in the entity is held by
benefit plan investors.  If benefit plan investment exceeds 25% of the value of
the equity interest,  the assets of PB III are treated as the assets of a plan
investing in PB III.     
    
     If the underlying assets of PB III are characterized as "plan assets,"
ERISA's fiduciary standards may be imposed upon PB III, the general partner, and
perhaps Quiet Systems Limited.  The cost and feasibility for PB III or the
general partner to comply with such standards and whether application of such
standards will adversely affect the performance of PB III or the general partner
cannot be predicted.  Additionally, if a plan asset is subject to the control
and management of a person other than the plan trustee, there may be an improper
delegation of the plan trustee's responsibility.     
    
     ERISA also requires that plan assets be valued to reflect market value as
of the close of each plan year.  It may not be possible to adequately value the
units from year to year, since there may not be a market for them and the
appreciation of any properties may not be shown in the value of the units until
PB III sells or otherwise disposes of its properties.     
    
     If the underlying assets of PB III are characterized as "plan assets," the
Internal Revenue Code may impose the prohibited  transaction excise taxes upon
the general partner and Quiet Systems Limited equal to 5% of the amount involved
and 100% of the amount involved, respectively, in the prohibited transaction.
Many of the transactions involving the general partner, Quiet Systems Limited,
PB III and employee benefit plans will constitute prohibited transactions unless
they qualify as exempt transactions.  Because of the inherently factual nature
of the determination, no assurance can be given that the transactions will
qualify as exempt transactions.  If excise taxes are imposed on the general
partner and Quiet Systems Limited, significant changes in the method of
operating PB III may become necessary. Such changes could result in increased
costs being incurred by PB III and have an adverse effect on its
performance.    
    
     Before investing employee benefits plan assets in PB III, you should also
consider that as a retirement plan,  it must be taxed on unrelated business
income  if income from all sources exceeds $1,000 per year.  Interest, as well
as gains or losses from the sale, exchange or other disposition of property,
including commodity futures contracts, are excluded from the computation of
unrelated business income.  Moreover, it appears that gains or losses on Section
1256 contracts marked-to-market at the end of the taxable year are also     

                                      80
<PAGE>
 
    
excluded from the computation of unrelated business income.  Even though no tax
may be due, a tax return (Form 990-T) must be filed for any year in which an
employee benefit plan's gross unrelated business income equals or exceeds
$1,000.  Prospective plan investors should consult their own legal and financial
advisors regarding these and other considerations involved in an investment in
PB III by a particular plan.     

     Notwithstanding the exclusion of any specific type of income from unrelated
business income, a tax-exempt limited partner will be taxed on its share of any
income from PB III to the extent that either such limited partner's investment
in PB III, or PB III's investment in the assets from which the income is
derived, is debt financed.  Such an investment will be debt financed if the
investment is made with the use of borrowed funds, or if it is reasonably
foreseeable that, as a result of such investment, future borrowing would be
necessary to meet anticipated cash requirements.
    
     Units may not be purchased with plan assets  if the general partner or
Quiet Systems Limited either:  (a) has investment discretion with respect to the
investment of such plan assets; (b) has authority or responsibility to give or
regularly gives investment advice with respect to such plan assets for a fee and
pursuant to an agreement or understanding that such advice will serve as a
primary basis for investment decisions with respect to such plan assets and that
such advice will be based on the particular investment needs of the plan; or (c)
is an employer maintaining or contributing to such plan.     
    
     The foregoing discussion is general in nature and is not intended to be
all-inclusive.  Because the issues under ERISA and the Internal Revenue Code are
complex and the potential consequences can be adverse, a fiduciary of a
qualified plan considering investment in PB III should consult with its own tax
or legal advisors with respect to the impact of all of the foregoing on such
qualified plan.     
    
     Any reference to the opinion of Nyemaster, Goode, Voigts, West, Hansell &
O'Brien, P.C. received by PB III is in all events subject to all assumptions,
exceptions and qualifications set forth in such opinion, and such opinion is
otherwise in all events only made upon all of the terms and conditions of such
opinion in the form rendered to PB III.  A copy of the opinion of Nyemaster,
Goode, Voigts, West, Hansell & O'Brien, P.C. will be provided to you upon
request.     


                       THE LIMITED PARTNERSHIP AGREEMENT
                       ---------------------------------
    
     This following is a summary of what PB III believes are some of the more
significant terms and provisions of the limited partnership agreement. A copy of
the limited partnership agreement is attached to this prospectus as Exhibit "A".
You will need to read the limited partnership agreement for complete details of
its terms and conditions.    
    
     Nature of PB III; Liability of Limited Partners.  The liability of a
     -----------------------------------------------                     
limited partner for the losses, debts and obligations of PB III will be limited
to the limited partner's capital contributions to PB III and the limited
partner's share of any undistributed assets of PB III, except as provided in the
following three paragraphs.    

                                      81
<PAGE>
 
    
     A limited partner may become liable as a general partner of a limited
partnership if the limited partner participates in the control of the limited
partnership's business or knowingly permits the limited partner's name to be
used in the name of the limited partnership.   PB III is structured to attempt
to avoid any limited partner from participating in the control of PB III's
business. The exercise of any rights of the limited partners set forth in the
limited partnership agreement will not cause any limited partner to participate
in the control of PB III's business for this purpose.     

    
     As discussed in "Transferability and Liquidation of Units" above, a limited
partner who has received the return of any part of his or her capital
contribution can be required to return the contribution to PB III for up to one
year after the return if necessary to pay creditors who extended credit to PB
III during the period the contribution was held by PB III.  If the capital
contribution was returned to the limited partner in violation of PB III's
limited partnership agreement or the Iowa Uniform Limited Partnership Act,
however, the limited partner can be required to return the contribution to PB
III for up to six years after the return.      

    
     If the certificate of limited partnership or a certificate of amendment or
cancellation of a limited partnership contains a false statement, a person who
incurs a loss by relying on the statement may recover damages from a limited
partner who knew the statement to be false at the time the certificate was
executed. The general partner will exercise its best efforts to assure that this
circumstance does not occur.    

    
     The general partner will be liable for all obligations of PB III which PB
III is not able to pay or satisfy.  The general partner will not, however, be
liable for the return or repayment of all or any portion of the capital or
profits of any limited partner.     

    
     

    
     Units.  Interests in PB III are evidenced by units.  Units which are issued
     -----                                                                      
to limited partners will be fully paid and nonassessable.     

                                      82
<PAGE>
 
    
     Management of PB III's Affairs.  The limited partners will not take part in
     ------------------------------                                             
the management or operation of the business or property of PB III and will have
no voice in the operations of PB III. Any participation by the limited partners
in the management of PB III will jeopardize their limited liability, as
discussed in "The Limited Partnership Agreement--Nature of PB III; Liability of
the Limited Partners" above.  Accordingly, under the limited partnership
agreement, responsibility for managing PB III and its business is vested solely
in the general partner.  See Sections 5.01 and 5.02 of the limited partnership
                         ---                                                  
agreement.     

    
     The general partner may make certain limited amendments to the limited
partnership agreement without the vote or consent of the limited partners.  See
                                                                            ---
Section 11.02 of the limited partnership agreement.     

    
     Any material change in PB III's basic investment policies or structure
will, however, require the prior written consent or vote of the limited partners
who hold at least a majority of the total number of outstanding units.  PB III's
"basic investment policies" for this purpose are only that:     

    
     .   it will not make any loans to the general partner or any other
         person,    
    
     .   it will not engage in pyramiding, and     
    
     .   it will not permit churning of its assets.     

    
Pyramiding generally means using an unrealized profit in an open position to
provide margin for additional futures contracts.  Churning generally means
excessive trading of PB III's account.  The limited partnership agreement
provides that changes in trading advisors or futures commission merchants or in
the  trading methods utilized by any trading advisor or in the types of
contracts or interests traded by PB III will not constitute a material change
for this purpose.     

                                      83
<PAGE>
 
    
     

    
     The limited partners who hold at least a majority of the outstanding units
may vote to:     

    
     .   amend the limited partnership agreement and PB III's certificate of
         limited partnership,     
    
     .   remove the general partner and elect a new general partner(s), and     
   
     .   cancel any contract with the general partner without penalty upon 60
         days prior written notice.    

    
Any amendment to the limited partnership agreement by the limited partners which
modifies the compensation of the general partner or which affects its duties or
obligations or its rights or protections will, however, need the consent of the
general partner. If the limited partners vote to remove the general partner, the
general partner will be entitled to liquidate its units.     

    
     Each limited partner shall be entitled to 1 vote for each outstanding whole
unit owned by the limited partner, and to a fractional vote in an amount equal
to any fractional unit owned by the limited partner.  The limited partnership
agreement provides that the vote of the limited partners who hold a majority of
the outstanding units is generally necessary for the limited partners to approve
or take any action submitted to a vote of the limited partners.  A unanimous
vote of the limited partners is, however, required to cause an assignee of units
to become a substituted limited partner over the objections of the assignor, and
in order to carry on the business of PB III after the withdrawal of all of the
general partners of  PB III.  The latter issue is discussed in "The Limited
Partnership Agreement--Termination and Dissolution of PB III" below.     

    
     The limited partners will appoint the general partner their attorney-in-
fact by executing the power of attorney which is included as part of the
subscription agreement that is required to purchase units.  The limited partners
also grant the general partner the power of attorney set forth in Section 12.03
of the limited partnership agreement.  The documents that may be executed by the
general partner on behalf of the limited partners under the powers of attorney
include amendments to the certificate of limited partnership and the limited
partnership agreement.

     Resignation or Withdrawal of General Partner.  The limited partnership
     --------------------------------------------                          
agreement provides that the general partner may resign if the general partner
can obtain the approval of the limited partners who hold at least a majority of
the outstanding units, and if the general partner can provide a successor
general partner satisfactory to those limited partners.     

    
     The general partner may also resign by giving at least 120 days prior
written notice to the limited partners.  There is therefore no assurance of the
general partner's continued service to PB III.  This creates a risk for
investors, as described in "Principal Risk Factors--The General Partner May
Resign at Any Time, Which Could Result in the Need to Terminate PB III"
above.    
    
     Admission of Other General Partners.  Any other individual or entity may be
     -----------------------------------                                        
admitted as an additional general partner with the consent of the limited
partners who hold at least a majority of the outstanding units.  Any additional
general partner will be permitted to continue and carry on the business of PB
III following the withdrawal of any other general partner.     

    
     Additional Offerings.  The general partner may terminate this offering at

any time.  The general partner may also make additional public or private
offerings of units. There is no maximum aggregate amount of units which may be
sold by PB III.     

    
     No limited partner shall have any preemptive or other right to acquire any
additional units.     

    
     The general partner can accept additional capital contributions from
existing limited partners.  Additional capital contributions from existing
limited partners can be in any amount, and will be effective as of the opening
of trading on the first business day of the month next following the date of the
general partner's acceptance of the capital contribution.     

    
     Partnership Accounting.  Each limited partner will have a capital
     ----------------------                                           
account. It will be credited with the amount of the limited partner's capital
contributions, and the limited partner's proportionate share of PB III's income
or gains.  The capital account will be debited with the limited partner's
proportionate share of PB III's deductions or losses, and the amount of any
distributions made to and liquidations made by the limited partner.    

    
     Profits and losses for each fiscal year will be allocated among the limited
partners pro rata based upon the number of units held by the limited 
partners.

     Distributions.  PB III is not required to make any distributions, and
     -------------                                                        
distributions will be made only as determined by the general partner, in its
sole discretion.  It is not anticipated that any distributions will ever be
made.  If distributions occur, they will be made pro rata based upon the number
of units held by  the limited partners.     

    
     Upon liquidation of PB III, the remaining assets of PB III will be
distributed to the limited partners in the proportion that the capital account
of each limited partner bears to the total capital accounts of all limited
partners.  If those distributions are not enough to return the full amount of a
limited partner's capital contribution, the limited partner will not have
recourse against any other limited partner.     

    
     Federal Tax Allocations.  At the end of each fiscal year, PB III's realized
     -----------------------                                                    
capital gain or loss and ordinary income or loss will be allocated among the
limited partners. The allocations will be made after having given effect to the
fees payable by PB III. Each limited partner's share of such items will need to
be included in the limited partner's personal income tax return.

     Termination and Dissolution of PB III.   PB III will be terminated on
     -------------------------------------                                
December 31, 2050.  PB III may also be terminated and dissolved before that time
if any of the events set out in the following paragraphs occurs.     

    
     PB III will be terminated upon the occurrence of any event specified under
the Iowa Uniform Limited Partnership Act as causing the dissolution of an Iowa
limited partnership.  The events which could cause a dissolution of PB III under
the Iowa Uniform Limited Partnership Act are as follows:     

    
     .   if PB III ceased to have any limited partners,     
    
     .   if all of the limited partners consented in writing to the dissolution
         of PB III,     
    
     .   if PB III is judicially dissolved, which could occur if a court
         determines that it is not reasonably practical to carry on PB III's
         business in accordance with the limited partnership agreement, or     
    
     .   if PB III is dissolved by the Iowa Secretary of State because PB III
         does not have a registered agent or registered office in Iowa for 60
         days or more or PB III does not notify the Iowa Secretary of State
         within 60 days that its registered agent or registered office has been
         changed, that its registered agent has resigned, or that its registered
         office has been discontinued.     

    
The general partner will exercise its best efforts to assure that none of the
above events occur.     

    
     PB III may be dissolved at any time by the general partner, in the general
partner's sole discretion.     

    
     PB III will also be dissolved if the general partner withdraws or ceases to
be the general partner, unless there is then at least one other general partner
who is willing to continue PB III's business, or unless the limited partners
unanimously elect to carry on PB III's business and elect a new general partner
within 90 days of the general partner's withdrawal.  This procedure is provided
for in Sections 9.01(a)(iii) and 9.03 of the limited partnership agreement.  As
discussed in "Admission of Other General Partners" above, the limited
partnership agreement provides that any new or additional general partners will
have the authority to carry on the business of PB III following the withdrawal
of any other general partner.     

    
     PB III may also be dissolved by the vote of the limited partners who hold
at least a majority of the outstanding units.

     Meetings.  No regular meetings of PB III will be held.  A meeting of the

limited partners may, however, be called by the general partner at any time and
for any purpose.     

    
     The general partner will call a meeting within 15 days after the general
partner receives a written request for a meeting which sets forth the purpose of
the meeting and is signed by limited partners who own at least 10% of the
outstanding units.     

    
     The general partner will give written notice of any meeting and the purpose
of the meeting to all limited partners.  All meetings will be held at a
reasonable time and place on a date no less than 30 nor more than 60 days after
the date of the general partner's written notice of the meeting.  The principal
office of PB III will be a reasonable place to hold a meeting.

     Reports to Limited Partners.  PB III's books and records are maintained at
     ---------------------------                                               
the offices of Schoenauer & Co., P.C., 328 Main Street, Ames, Iowa 50010.     
    
     PB III will provide limited partners with monthly statements of account, in
the form required by the regulations of the Commodity Futures Trading
Commission.  PB III will also provide limited partners with an annual report
containing financial statements.  The annual financial statements will be
certified by independent certified public accountants.  The limited partners
will also receive information necessary for the preparation of their annual
federal income tax returns by not later than March 15 of each year.     
    
     PB III will also be subject to the informational requirements of the
Securities Exchange Act of 1934 for at least as long as PB III's registration
statement with the Securities and Exchange Commission is effective.  PB III will
accordingly provide the limited partners with the information required under the
Exchange Act during at least that period of time, which will include quarterly
reports on Form 10-QSB and annual reports on Form 10-KSB.     
    
     Limited partners or their duly authorized representatives may inspect and
copy (at their cost) PB III's books and records during normal business hours
upon reasonable written notice to the general partner.     
    
     As indicated above, PB III is currently subject to the informational
requirements of the Securities Exchange Act, and PB III will accordingly file
periodic reports and other information with the Securities and Exchange
Commission.  Copies of those reports and other information can be obtained from
the public reference facilities of the Securities and Exchange Commission
located at 450 Fifth Street, N.W., Washington, D.C. 20549 and at the
Commission's regional offices located at Seven World Trade Center, New York, New
York 10048 and Citicorp Center, 500 W. Madison Street, Chicago, Illinois 60661-
2511.  The  Commission also maintains a Web site, and documents which are filed
by PB III with the  Commission may also be inspected at that Web site at
http://www.sec.gov.     
    
     PB III has filed with the Securities and Exchange Commission a Registration
Statement on Form SB-2 under the Securities Act of 1933 regarding the units
offered by this prospectus.  This prospectus does not contain all of the
information set forth in the registration statement.  The registration statement
may be inspected and copied at prescribed rates at the offices of the Securities
and Exchange Commission referred to above.

                              PLAN OF DISTRIBUTION
                              --------------------
    
     The units are being offered and sold only by the underwriter, Vacation
Investors, Inc.  The units are being offered on a best efforts basis.  The
underwriter has not committed to purchase any unsold units.     
    
     PB III will not pay any underwriting or selling commission or other fee to
the underwriter.  The underwriter will receive compensation for its sales
efforts, however, from the general partner.     
    
     The compensation payable to the underwriter by the general partner is a fee
of a potential maximum amount of 5.625% of the subscriptions which have been
collected by PB III.     

                                      90
<PAGE>
 
    
The fee is payable in three equal installments. The first installment is payable
within 10 business days of the close of the month in which the subscription was
collected by PB III. The second and third installments are payable on the 2 and
3 year anniversaries of the date the subscription was effective as a capital
contribution to PB III, which will be the first business day of a month. The
second and third installments will not be payable, however, if the limited
partner who contributed the subscription has caused the limited partner's
capital account to fall below the amount of the subscription through
liquidations of units by the limited partner. Adjustments will be made to the
limited partner's capital account for this purpose to take away the effect of
reductions to the limited partner's capital account caused by distributions made
to the limited partner or by any trading losses that have been allocated to the
limited partner's capital account.     
    
     If a limited partner contributes subscriptions in different months, the
underwriter's fee will be calculated and payable separately based on each
subscription.  If the limited partner later liquidates units, the amount of 
the     

                                      91
<PAGE>
 
    
liquidation proceeds will be applied pro rata against the subscriptions for
purposes of determining whether the second and third installments of the fee are
payable.     
    
     The underwriter will not receive any further fees from the general partner
after the date of the termination of the sales agreement between PB III, the
general partner and the underwriter.     
    
     The general partner may also pay some of the costs and expenses of the
underwriter, subject to certain maximum limitations set forth in the sales
agreement.     
    
     
    
     The underwriter is an Iowa corporation which was incorporated on April 15,
1994.  The underwriter's registration as a fully disclosed broker dealer with
the Securities and Exchange Commission became effective on May 11, 1994, and the
underwriter became a member of the National Association of Securities Dealers on
July 21, 1994.  Mr. Raun is the sole shareholder, director and officer of the
underwriter.  Mr. Raun is also a registered representative and the general
securities principal and financial and operations principal of the underwriter.
As of the date of this prospectus, the underwriter had 6 registered
representatives.     
    
     The principal business of the underwriter as of the date of this prospectus
was the offering of the units of PB III and the units of limited partnership
interest in Portfolio Boost I, L.P. and Portfolio Boost II, L.P.  The
underwriter may also participate in the offering of other pools sponsored by the
general partner or by  others.  The underwriter also offers general brokerage
services to the public.     
    
     The underwriter's prior experience in public offerings is limited to the
underwriter's offering of units of limited partnership interest in CBC-RT.  CBC-
RT is another Iowa limited partnership for which the general partner serves as
the general partner.  CBC-RT is closed to new investors, but it previously
offered its units of limited partnership interest pursuant to Regulation A under
the federal Securities Act of 1933.  Mr. Raun was the only registered
representative of the underwriter who participated in CBC-RT's offerings.  The
underwriter has also offered units of limited partnership interest in one other
Iowa limited partnership.  The offering of that limited partnership was pursuant
to Rule 504 under federal Securities Act  of  1933, and the only registered
representative of the underwriter participating in that offering  was  the
individual who serves as the general partner of that limited partnership.  That
limited partnership was closed to new investors as of the date of this
prospectus.  The underwriter therefore has limited experience in public
offerings.     
    
     Mr. Raun has participated in offering units of limited partnership interest
in the limited partnerships for which he serves as the general partner on an
individual basis.  All of those offerings were, however, pursuant to exemptions
from registration available at the      

                                      92
<PAGE>
 
    
federal and state levels.     
    
     Units are initially offered for sale at fixed value of $1,000 per unit.
The $1,000 amount was arbitrarily set by the general partner.  It was not based
on past or expected earnings and does not represent that the units have or will
have a market value of or can be resold or liquidated at that price.     
    
     PB III may commence trading after it has sold 500 units. After PB III has
commenced trading, units will be offered at the net asset value per unit as of
the opening of trading on the effective date of the purchase. The effective date
of a purchase will be the first business day of the month that follows the date
on which the general partner accepts a subscription agreement and the capital
contribution from the limited partner. The organizational and offering expenses
incurred by PB III prior to the effective date of its initial registration
statement filed with the Securities and Exchange Commission are amortized over a
period of 5 years for purposes of calculating the net asset value per unit.    
    
     Funds from subscriptions accepted prior to the sale of 500 units will be
deposited and held in an escrow account at First American Bank, Fort Dodge,
Iowa, until 500 units have been sold.  The escrow agreement requires PB III and
the underwriter to transmit all monies received from subscribers during the
escrow period to First American Bank by at least 12:00 noon of the next business
day.  First American Bank will receive an aggregate fee of the greater of (a)
$300.00; or (b) an amount determined by multiplying the total number of checks
received and issued by First American Bank, by $5.00.     

     Subscription payments deposited in the escrow account may not be withdrawn
by any subscriber under any circumstance.
    
     If 500 units are not sold before October 28, 1999, this offering will
terminate.   If that happens, all amounts paid by a subscriber will be returned
to the subscriber within 10 business days of October 28, 1999, along with the
subscriber's pro rata share of all interest earned on subscriptions deposited in
the escrow account.  Any units which are purchased by the general partner or Mr.
Raun will not be counted in determining whether the 500 units required to break
escrow have been sold.     

                                      93
<PAGE>
 
    
     The sale of the 500 units should not be relied upon as any indication of
the merits of this offering because the required sale of those units is not
intended to protect investors or to show PB III is a good or safe 
investment.     
    
     The escrowed funds will be released for use by PB III on the first business
day after the 500 units have been sold.  If  PB III breaks escrow, this offering
will continue until the earlier of such time as all of the units offered hereby
have been sold, or this offering is terminated by the general partner, in its
sole discretion.  All subscriptions accepted by the general partner after the
breaking of escrow will be immediately available for use in PB III's 
business.     
    
     The underwriter will maintain a web site at www.vacationinvestors.com.  The
web site contains information regarding this offering.     


                             SUBSCRIPTION PROCEDURE
                             ----------------------
    
     In order to purchase units, you will need to execute a copy of the
subscription agreement that is attached to this prospectus as part of Exhibit
"B," and deliver the executed subscription agreement and the full purchase price
for the units subscribed for to the general partner.  You will also need to
return an executed acknowledgment of receipt of this prospectus, and a completed
and executed suitability standards requirement form.  Those documents are also
attached to this prospectus as part of Exhibit "B".     
    
     
    
     The minimum subscription is $5,000 for first time investors.  Subsequent
investments by existing limited partners may be in any amount as the general
partner may accept.     
    
     Unless you are from California, in order to purchase units, you must have
at least either:     
    
     a.   a minimum net worth of $150,000, or     
    
     b.   a minimum annual gross income of $45,000 and a minimum net worth of
          $45,000.     
    
If you are a resident of California or an entity with its principal place of
business in California, you must have at least either:     

                                      94
<PAGE>
 
    
     a. a minimum net worth of $250,000, or     
    
     b. a minimum annual gross income of $65,000 and a minimum net worth of
        $100,000.       
    
Your net worth for these purposes must be determined exclusive of your home,
home furnishings and automobiles. In the case of sales to fiduciary accounts,
the net worth and income standards may be met by the beneficiary, the fiduciary
account, or by the donor or grantor who directly or indirectly supplies the
funds to purchase the units.     
    
     The subscription agreement includes a representation and warranty that the
subscriber meets the above suitability standards.  The subscription agreement
also contains various other representations, warranties, agreements, and
acknowledgments, and you should therefore carefully review the subscription
agreement.  You will also be required by the subscription agreement to agree to
indemnify PB III, the general partner, the underwriter and their affiliates and
agents against all losses, liabilities, damages, costs or expenses (including
court costs, arbitration costs and reasonable attorneys' fees) which are
incurred by any of them because of any breach or default by you of your
subscription agreement.     
    
     The total purchase price for the units must be paid at the time of
executing the subscription agreement.  The purchase price must be paid in cash
or its equivalent.     
    
     All subscriptions are irrevocable, except only as may be provided by the
securities laws of your state.  The general partner has the right, however, to
totally or partially reject any subscription for units.  The general partner may
require you to provide additional information and documentation.     

     PB III will issue fractional units, rounded up to the sixth decimal point,
to the extent necessary to fill an accepted subscription for units.
    
     The general partner will try to deposit checks received from subscribers
after the release of funds from escrow promptly following the acceptance of the
subscription agreement.  IRA investments may be effective as of the first
business day of the month even though funds have not been received if the check
and the IRA trustee's executed signature page to the subscription agreement are
received by the 20th of the month.     
    
     All units will be issued subject to the collection of good funds, and any
units issued to a subscriber who has not provided collectible funds (whether in
the form of a bad check or draft, or otherwise) will be canceled.

                                                         --                  
limited partner's option: (c) 7 nights lodging in any Hyatt Hotel or Resort
located in the United States, the Caribbean, Canada or Mexico; and (d) a $700
Hyatt spending allowance (the "land option").     
    
     A dinner meeting will be provided to the limited partners participating in
the group trip option of the Platinum Award.  The cost of the dinner meeting
will be borne by the applicable limited partnerships as is discussed in "Award
Conditions, Restrictions and Procedures" below.     
    
     In order to qualify for the Platinum Award, a limited partner must (a) be a
limited partner in at least three limited partnerships for which the general
partner serves as the commodity pool operator; and (b) have made a combined
capital contribution of $250,000 or more to such limited partnerships and have
maintained that capital contribution (adjusted only for liquidations by the
limited partner) for a consecutive period of at least 12 full months.  Further
requirements and conditions are set forth below in "Award Conditions,
Restrictions and Procedures."     

     Award Conditions, Restrictions and Procedures.  Accounts held in more than
     ---------------------------------------------                             
one name are only entitled to one Award, regardless of the number of owners of
or persons named on the account.  Limited partners with separate accounts and
residing in the same household may, however, combine their capital contributions
for purposes of qualifying for the Awards.
    
     The general partner will give a written notice to each limited partner who
qualifies for any Award within 30 days of the date the limited partner qualifies
for the Award.     
    
     A limited partner who has qualified for the Bronze Award or the Silver
Award or who has selected the land option for the Gold Award or Platinum Award
will have 12 months from the date of the general partner's qualification notice
to utilize the Award.  The limited partner must provide the general partner with
written notice of the desired Hyatt location and the dates at that location.
The limited partner will be provided with a certificate for use at the Hyatt
location selected by the limited partner.  Once the certificate has been issued,
all risk of loss for the certificate passes to the limited partner.  If a
limited partner has not utilized the Award within 12 months of the date of the
general partner's qualification notice to the limited partner, the limited
partner will be deemed to have waived the Award.  All other costs and expenses
of the limited partner will be borne by the limited partner, such as airfare or
other travel costs, meals, entertainment and lodging at the chosen location
beyond the nights payable by the general partner.

     The dates and location of the group trip option for the Gold Award and the
Platinum Award will be selected by the general partner.  The general partner
will give each qualifying limited partner a written notice (the "trip notice")
of such dates and location at least 6 months prior to the date of the group
trip.  A qualifying limited partner who desires to use the land option as
provided above must give the general partner written notice within 30 days of
the date of the general partner's trip notice.  A limited partner selecting the
land option will not be allowed to change back to the group trip.  A limited
partner who wants to utilize the group trip option must confirm dates and
departure airport no less than 120 days in advance of the departure date.  Any
penalties due to changes by the limited partner will be the limited partner's
responsibility.  If the general partner has not received written confirmation
from a qualifying limited partner within 120 days in advance of the departure
date for the group trip, the limited partner shall be deemed to have waived the
Award.  The limited partnerships in which the qualifying limited partner is a
limited partner shall provide, at the limited partnerships' cost, one dinner
meeting on the first night of each group trip.  The cost of the dinner meeting
will be borne proportionately by the limited partnerships in question, based
upon the capital contributions of the qualifying limited partner.  Except for
the dinner meeting on the group trip option of the Gold Award and the Platinum
Award, all other costs and expenses of a qualifying limited partner will be
borne by the limited partner, such as transportation costs to the departure
airport selected by the limited partner, meals, entertainment and lodging at the
chosen location beyond the nights payable by the general partner.     
    
     Once a trip has been scheduled and booked, it will only be rescheduled due
to weather or other difficulties or problems in the sole discretion of the
general partner.     
    
     The general partner will provide the appropriate Award to a limited partner
for each 12 month period that the limited partner otherwise meets the
qualifications set forth above.  As of the date of this prospectus, a limited
partner could therefore have the possibility of qualifying for up to a maximum
of 3 awards.     
    
     The rooms that will be provided at the location of each Award will be
double occupancy rooms on any night of the week or weekend, subject to
availability.  All Hyatt spending allowances can only be utilized for purchases
at the Hyatt location and are only valid for use during the dates of the trip.
They are not convertible into cash.     
    
     Except for PB III's proportionate cost of the dinner meeting to be provided
in the group trip option of the Gold Award and the Platinum Award, the Awards
will not affect the value of the units because the cost and expense of the
Awards will be paid by the general partner.  You should note, however, that PB
III will not receive any direct benefits for its payment for the dinner meetings
for any qualifying limited partners.     
    
     No compensation or reimbursement will be paid to any limited partner who
fails or determines not to utilize any Award.     
    
     No limited partner will be entitled or allowed to utilize more than one
Award in any given 12 month period.  For example, a Gold Award qualifier is not
entitled to take advantage of the Gold, Silver, and the Bronze Award, and a
Silver Award qualifier is not entitled to take advantage of both the Silver and
Bronze Awards, etc.

     You should also review "Principal Risk Factors--You May Not Be Able to Use
a Vacation Award Even if You Have Qualified For One" above for certain risks
applicable to the Awards.    
    
     As indicated above, the general partner has only committed to provide the
Awards to limited partners who qualify for the Awards prior to February 1, 2002.
No promise or representation is made that the general partner will offer the
same or similar awards or any other trip or incentive of any nature at any
subsequent time.  The Awards may have tax consequences for you.  For example, it
is likely that the value of the Awards will be treated as income. Accordingly,
you should consult with your own legal, tax and other professional advisors as
to the possible tax consequences of the Awards.

                                  APPENDIX 1

                     Supplemental Performance Information

   
The performance information presented in this Appendix 1 is hypothetical
performance information.  As such, you should be aware of the following:       

Hypothetical performance results have many inherent limitations, some of which
are described below. No representation is being made that any account will or is
likely to achieve profits or losses similar to those shown. In fact, there are
frequently sharp differences between hypothetical performance results and the
actual results subsequently achieved by any particular trading program.

One of the limitations of hypothetical performance results is that they are
generally prepared with the benefit of hindsight. In addition, hypothetical
trading does not involve financial risk, and no hypothetical trading record can
completely account for the impact of financial risk in actual trading. For
example, the ability to withstand losses or to adhere to a particular trading
program in spite of trading losses are material points which can also adversely
affect actual trading results. There are numerous other factors related to the
markets in general or to the implementation of any specific trading program
which cannot be fully accounted for in the preparation of hypothetical
performance results and all of which can adversely affect actual trading
results.

    
PB III'S trading advisor has had no experience in trading actual accounts for
itself or for customers. Because there are no actual trading results to compare
to the hypothetical performance results, you should be particularly wary of
placing undue reliance on these hypothetical performance results.       

Further, past performance is in no event necessarily indicative of future
results.

  PB III is a single advisor pool that does not have a guarantee feature.  The
  following capsules show hypothetical performance information for PB III since
  an assumed inception of trading by PB III on January 1, 1981, and year-to-date
  (through November 30, 1998).  PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE
  OF FUTURE RESULTS.

***  "Net Asset Value" means total assets minus total liabilities, determined on
     an accrual basis of accounting in accordance with generally accepted
     accounting principles, with each open position accounted for at fair market
     value.
    
**** "Worst Peak-to-Valley Draw-Down" is defined by applicable Commodity
     Futures Trading Commission regulations to mean the greatest cumulative
     percentage decline in month-end net asset value due to losses sustained by
     a pool, account, or trading program during any period in which the initial
     month-end net asset value is not equaled or exceeded by a subsequent month-
     end net asset value.     
    
Assumptions to supplemental performance information:     
- ----------------------------------------------------
    
1. $1,250,000 in capital was contributed as of 1/1/81 and no additional capital
   contributions were made during the entire period shown above.     
2. No withdrawals or distributions were made during the entire period shown
   above.
    
3. Brokerage commissions of $11.00, National Futures Association and exchange
   fees of $3.50 and slippage of $75 per contract were included in the costs.
   These rates are consistent with current industry standards.  Slippage is
   calculated due to the fact that the trades were done on a hypothetical basis
   and not in real market situations.     
    
4. Interest income will be earned on the trading account of PB III.  For
   purposes of the above calculations, a 5% per annum interest rate was used.
   Actual interest earnings would have been higher during the period shown.
   However, to maintain a conservative reporting process, the 5% rate was 
   used.     
    
5. The management fee and incentive fee payable to the general partner as set
   forth in the prospectus were both utilized for purposes of the above
   calculations. See the section of the prospectus entitled "Description of
   Charges to PB III."      
6. The quantitative, non-discretionary, systematic approach of Quiet Systems
   Limited was applied to actual market data for the periods indicated in order
   to determine trading results.
7. All amounts displayed are in U.S. Dollar denominations
    
You should carefully review the disclosures on the cover page to this Appendix 1
regarding the many limitations which are inherent in hypothetical performance
information.

                         LIMITED PARTNERSHIP AGREEMENT

     THIS LIMITED PARTNERSHIP AGREEMENT ("Agreement") is made as of the date set
forth on the signature page hereof by and among Portfolio Boost, L.L.C. (the
"General Partner"), as general partner of Portfolio Boost III, L.P. (the
"Partnership"); the person designated on the signature page hereto as the
initial limited partner (the "Initial Limited Partner"); and the persons who may
hereafter become limited partners of the Partnership (collectively, the "Limited
Partners"). The General Partner and the Limited Partners are at times
collectively referred to herein as the "Partners".

                         ARTICLE I: General Provisions

     1.01  Formation of Partnership.  The Partnership is hereby formed by the
           ------------------------
General Partner and the Initial Limited Partner under the provisions of the Iowa
Uniform Limited Partnership Act, Chapter 487 of the Code of Iowa, as amended and
as may be amended from time to time (the "Act"). The rights and liabilities of
the Partners shall be as provided in the Act, except as otherwise expressly
provided in this Agreement. The Initial Limited Partner's contribution of $1,000
will be refunded upon admission of the first Limited Partner acquiring a Unit
(as that term is defined in Section 1.11 below), and the Initial Limited Partner
will thereupon withdraw from the Partnership. The Initial Limited Partner may,
however, purchase Units in the Partnership.

     1.02  Certificate of Limited Partnership.  The General Partner shall
           ----------------------------------
execute a Certificate of Limited Partnership for the Partnership (the
"Certificate") and file the Certificate in the Iowa Secretary of State's office,
and in such other public offices as deemed advisable in the discretion of the
General Partner. Amendments to the Certificate shall also be duly executed and

           ----------------------------------------------
become effective and the Partnership may commence business upon the filing of
the Certificate in the Iowa Secretary of State's office, and shall continue

           -----------------------------
this Agreement is Portfolio Boost, L.L.C., whose main business address is

office in Iowa as provided in Section 1.05 above.

     1.08  Title to Partnership Property.  All property owned by the
           -----------------------------
Partnership, whether real or personal or tangible or intangible, shall be deemed
to be owned by the Partnership as an entity, and no Partner, individually, shall
have any ownership interest in any such property.

     1.09  Filing of Other Certificates.  The General Partner shall file and
           ----------------------------
publish all certificates, notices, statements or other instruments as may be
required by law for the operation of a limited partnership in all jurisdictions
where the Partnership elects to do business.

     1.10  Expenses.  Each Partner shall bear any personal expenses incurred in
           --------
connection with the acquisition of the Partner's Units. The Partnership will
pay, without limitation, all organizational expenses of the Partnership and all
costs and expenses incurred in the offering and sale of Units, including the
costs of registration of Units under federal and applicable state securities
laws; producing the registration statement and the prospectus used to register
and offer Units and other promotional materials, documents and forms; filing
fees and taxes under applicable partnership and securities laws; accounting and
legal fees; escrow fees; and all other costs and expenses of organizing and
qualifying the Partnership and in offering and selling Units. The organizational
and offering expenses to be paid by the Partnership shall not, however, exceed
fifteen percent (15%) of the total Capital Contributions (as that term is
defined in Section 2.01(a) below) of all Limited Partners. Any deficiency in
such expenses shall be borne by the General Partner, and all such expenses shall
be borne by the General Partner in the event the General Partner has not
accepted subscriptions for at least the Minimum Units before the close of the
Minimum Units Offering Period (as those two terms are defined in Section 2.01(c)
below). The Partnership may pay all costs and expenses directly or may reimburse
others, including the General Partner, for all Partnership costs and expenses
which have been paid by such other persons.

     1.11  Partnership Interests.  The interests of the Partners in the
           ---------------------
Partnership shall be designated as units ("Units"), as more further described
and defined in Section 2.01(c) below.


                       ARTICLE II: Capital Contributions

     2.01  Capital Contributions.
           ---------------------

     (a)  Capital Contribution Defined.  The term "Capital Contribution" means,
          ----------------------------
with respect to each Partner, the sum of all cash (or its equivalent)
contributed to the Partnership by the Partner. No Partner shall receive interest
on any Capital Contribution. A Partner may withdraw the Partner's Capital
Contribution only as provided in this Agreement. No Partner is required to make
any contribution to the Partnership other than the Partner's initial Capital
Contribution. The aggregate of all Capital Contributions shall be available to
the Partnership to carry on its business.

     (b)  Capital Contribution of General Partner.  The General Partner may make
          ---------------------------------------
Capital Contributions (in cash or its equivalent) from time to time, in the
General Partner's sole discretion. All Capital Contributions of the General

                                       2
<PAGE>
 
Partner shall be evidenced by Units, and the General Partner shall have the same
rights with respect to Units as do the Limited Partners, except as otherwise
expressly provided in this Agreement. No Units held by the General Partner shall
be counted in determining whether the Minimum Units have been sold. Upon the
dissolution and termination of the Partnership, the General Partner will
contribute to the Partnership an amount equal to the deficit balance, if any, in
the General Partner's capital account.

     (c)  Capital Contribution of Limited Partners.  Each Limited Partner shall
          ----------------------------------------
make a Capital Contribution (in cash or its equivalent) at the time of
subscription for the Limited Partner's Units in the amount set forth in the
Limited Partner's Subscription Agreement. The purchase price per Unit prior to
the commencement of trading by the Partnership shall be One Thousand Dollars
($1,000) per Unit. The Partnership shall not commence trading unless and until
the General Partner has accepted subscriptions for at least Five Hundred (500)
Units (the "Minimum Units"), which must occur within nine (9) months of the
effective date of the Registration Statement to be filed with the Securities and
Exchange Commission (the "SEC") with respect to the Minimum Units (the "Minimum
Units Offering Period"). The Partnership may commence trading at any time after
the funds for the Minimum Units have been released from escrow (at which time
subscribers shall first be admitted to the Partnership as Limited Partners). If
the General Partner has not accepted subscriptions for the Minimum Units prior
to the close of the Minimum Units Offering Period, the offering of the Units
shall terminate and all amounts paid by subscribers for Units shall be returned
in the manner provided in the subscribers' Subscription Agreements. Units may be
offered and sold after the Partnership has commenced trading, in the sole
discretion of the General Partner. The purchase price per Unit after the
Partnership has commenced trading shall be the Net Asset Value Per Unit (as that
term is defined in Section 2.01(d) below) as of the opening of trading on the
effective date of the purchase (which date is specified in Section 8.06 below).
The Partnership will issue fractional Units, rounded up to the sixth decimal
point, to the extent necessary to fill an accepted subscription for Units.

     All Units shall be issued subject to the collection of good funds, and any
Units issued to a subscriber who has not provided collectible funds shall be
canceled.

     (d)  Net Assets; Net Asset Value Per Unit.  "Net Assets" of the Partnership
          ------------------------------------
for purposes of this Agreement means the Partnership's total assets minus the
Partnership's total liabilities, determined in accordance with generally
accepted accounting principles, except (i) that for purposes of calculating the
Net Asset Value Per Unit, Net Assets shall be determined by amortizing all
organizational and offering expenses incurred by the Partnership prior to the
effective date of the initial registration statement filed by the Partnership
with the SEC over a period of five (5) years; and (ii) as may be otherwise
provided herein.

     The term "Net Asset Value Per Unit" for purposes of this Agreement means
the Net Assets of the Partnership at the time of calculation divided by the
aggregate number of outstanding Units at that time.

     2.02  Termination of Offerings; Additional Offerings.  The General Partner
           ----------------------------------------------
may, in its sole discretion, terminate any offering of Units. The General
Partner may also register Units and/or make additional public or private
offerings of Units, in its sole discretion. The General Partner does not,
however, have any obligation or duty to register any Units with any authority.
No Limited Partner shall have any preemptive or other rights with respect to the
issuance or sale of any additional Units. No Limited Partner shall have the
right to consent to the admission of any additional Limited Partners or to any
additional Capital Contributions made by any existing Partner. There is no
maximum aggregate amount of Units which may be sold by the Partnership.

                 ARTICLE III: Allocation of Profits and Losses

     3.01  Profits and Losses.  Profits and losses for each fiscal year of the
           ------------------
Partnership shall be allocated among the Partners pro rata based upon the
respective number of Units held by the Partners. For purposes of determining the
profits, losses or any other items allocable to any period, profits, losses, and
any such other items shall be determined on a daily, monthly, or other basis, as
determined by the General Partner using any permissible method under Section 706
of the United States Internal Revenue Code and the regulations thereunder.

                                       3
<PAGE>
 
     3.02  Allocation of Distributions Upon Assignment of a Unit. The profits
           ------------------------------------------------------
or losses of the Partnership attributable to any assigned Unit and any
distributions made with respect to such Unit shall be allocated to the assignor
up to and including the effective date of the assignment, and to the assignee
thereafter.

     3.03  Capital Account Balance.  A capital account shall be established for
           ------------------------
each Partner and shall be credited with (i) the amount of cash paid to the
Partnership as the Partner's Capital Contribution, and (ii) the share of
Partnership income or gains allocable to the account; and shall be debited with
(x) the share of Partnership deductions or losses allocable to the account, and
(y) the amount of any distributions made to and liquidations made by the Partner
with respect to the account. The manner in which capital accounts are to be
maintained pursuant to this Section 3.03 is intended and shall be construed so
as to comply with the requirements of Internal Revenue Code Section 704 and the
regulations promulgated thereunder, and in the event there exists any
inconsistency the Internal Revenue Code and said regulations shall control.

     3.04  General.  The respective interests of the Partners in the profits and
           --------
losses of the Partnership shall remain as set forth herein unless changed by
amendment to this Agreement or by an assignment or liquidation of a Unit. For
tax purposes, all items of income, gain, loss, deduction or credit shall be
allocated among the Partners according to the same percentages and provisions
for allocating profits and losses set forth in this Article III.

                           ARTICLE IV: Distributions

     4.01  Distributions.  The Partnership is not required to make any
           --------------
distributions to the Partners, and any distributions by the Partnership will be
made only at such times and in such amounts as are determined by the General
Partner, in its sole discretion. Any distributions which are made shall be made
pro rata based upon the respective number of Units held by the Partners. This
Section 4.01 is not applicable to distributions to be made upon the dissolution
and liquidation of the Partnership, which circumstance is governed by Section
9.02 below.

     4.02  No Priority.  No Limited Partner shall have the right to receive
           ------------
property other than cash in connection with any distribution, whether upon
winding up of the Partnership or otherwise and whether or not it shall
constitute a return of capital. No Limited Partner shall have priority over any
other Limited Partner as to any distributions, whether upon winding up of the
Partnership or otherwise, the return of any Capital Contribution or as to
allocations of profits or losses.

     4.03  Liquidation of Units.  A Limited Partner may withdraw from the
           ---------------------
Partnership and liquidate the Units held by the Limited Partner only with the
consent of the General Partner, which consent shall be given only if the
following conditions are satisfied:

          (a)  A Limited Partner must give the General Partner written notice (a
     "Liquidation Notice") of the intention of the Limited Partner to liquidate
     Units, and stating the date upon which the liquidation is desired, which
     date must be the first business day of any month. The Liquidation Notice
     must be received by the General Partner no later than 12:00 noon on the
     sixtieth (60th) business day immediately preceding the desired effective
     date of liquidation or by such later date as may be acceptable to the
     General Partner, in the General Partner's sole discretion.

          (b)  Any liquidation request approved by the General Partner shall be
     effective as of the opening of trading on the first business day of the
     month specified in the Liquidation Notice.

          (c)  The liquidation price per Unit shall be equal to the Net Asset
     Value Per Unit as of the effective time and date of the liquidation. From
     the time of the General Partner's receipt of a Liquidation Notice to the
     effective time and date of the liquidation, the Units will remain at risk
     in the business of the Partnership and the liquidation price for the Units
     shall not be fixed. Subsequent to the effective time and date of a
     liquidation, however, the liquidation price per Unit shall be fixed at the
     Net Asset Value Per Unit as of the effective time and date of the
     liquidation.

          (d)  Subject to subparagraph (a) above and to the following, the
     General Partner shall honor all Liquidation Notices in the order they are
     received (on the basis of postmark or delivery, with the General Partner
     selecting Units for liquidation by lot with respect to Liquidation Notices
     received on the same date). If, however, the number of

                                       4
<PAGE>
 
     liquidations requested for any month or over any other given period of
     time, in the opinion of the General Partner, threatens the termination of
     the Partnership or the Partnership's tax year or is otherwise detrimental
     to the tax status of the Partnership, the General Partner may (but is not
     required to) select by lot only so many liquidations as will, in its
     judgment, not result in such consequences. Any Units not liquidated in this
     event shall remain at risk in the business of the Partnership and shall not
     be liquidated absent another separate Liquidation Notice given in the
     manner provided in this Section 4.03. In addition, the General Partner may
     (but is not required to) temporarily suspend all liquidations if, in the
     General Partner's judgment, special circumstances exist such that
     additional liquidations would impair the ability of the Partnership to meet
     its objectives, and under special circumstances the Partnership may also
     (but is not required to) delay payment for liquidated Units until the
     special circumstances have been remedied or otherwise rectified. Examples
     of special circumstances for either of these purposes include (i) the
     inability to generate sufficient cash to effect liquidations, (ii) where
     such cash can only be generated by sustaining significant losses, (iii) the
     inability to liquidate open positions, or (iv) the default or delay in
     payments which are due the Partnership from brokers or other persons. In
     the event of a suspension of liquidations, all Units will remain at risk in
     the business of the Partnership and shall not be liquidated absent a
     Liquidation Notice given following the lifting of the suspension by the
     General Partner and in the manner otherwise provided in this Section 4.03.

          (e) In the case of a notice given pursuant to Section 7.04(a)(i)
     below, trading by the Partnership shall be temporarily suspended for a
     period of thirty (30) calendar days, beginning on the date of such notice,
     during which time Limited Partners shall have the right to request
     liquidation of their Units. The General Partner shall honor all liquidation
     requests which are received by the General Partner prior to the close of
     said thirty (30) calendar day period, subject to, however, and in
     accordance with the provisions of Sections 4.03(c) and 4.03(d) above and
     4.03(f) below. Liquidations in this event shall be effective as of the
     opening of trading on the business day next following the General Partner's
     receipt of written notice from the Limited Partner.

          (f) The General Partner shall give written notice to a Limited Partner
     within ten (10) days after the first business day of the applicable month
     of whether or not the Limited Partner's Units have been liquidated. Payment
     for liquidated Units shall be made by the Partnership within thirty (30)
     days after the first business day of the applicable month, subject,
     however, to delays in payment pursuant to subparagraph (d) above.

A Limited Partner may request liquidation of less than all of the Limited
Partner's Units upon the same terms and conditions as set forth above; provided,
however, that the General Partner may, in the General Partner's sole discretion,
refuse any such request for a partial liquidation if the liquidation would cause
the capital account of the Limited Partner to be less than the minimum initial
investment amount as then established by the General Partner.

     4.04  Retirement Accounts.  The General Partner may, in the General
           --------------------
Partner's sole discretion, require any Limited Partner which is an IRA or a
retirement plan or employee benefit plan subject to Title I of the United States
Employee Retirement Income Security Act of 1974 ("ERISA") to either: (i)
withdraw from the Partnership, in whole or in part, through liquidation of some
or all of the Limited Partner's Units, or (ii) make immediate distributions to
the Limited Partner in such amount as determined by the General Partner; if such
liquidation or distribution is, in the General Partner's sole discretion,
necessary or appropriate to cause the Partnership, the General Partner or any
Limited Partners to avoid being subject to or in violation of any of the
provisions of ERISA or regulations promulgated pursuant thereto or any similar
or successor act, statutes or regulations.

                             ARTICLE V: Management

     5.01  Management of the Partnership.  The management and control of all of
           ------------------------------

           ---------------------------------

     Partner determines to be appropriate to carry out the business and affairs
     of the Partnership, whether or not any such persons so employed or retained
     are the General Partner or are affiliated or related to any Partner, all
     upon terms satisfactory to the General Partner, and to pay such fees,
     salaries, wages and other compensation to such persons as the General
     Partner shall in its sole discretion determine;

          (c)  to pay, extend, renew, modify, adjust, contest, submit to

          (d)  to pay all fees and make all other expenditures which the General
     Partner, in its sole discretion, deems appropriate in connection with the
     organization of the Partnership, the registration, offering and sale of
     Units, the operation of the Partnership's business, and/or the carrying out
     of the General Partner's obligations and responsibilities under this
     Agreement;

          (e)  to accept additional Capital Contributions from any Partner, to

     without notice to or the consent of any Limited Partner;

          (f)  to invest any funds of the Partnership that are not committed to
     the conduct of the Partnership's business as the General Partner shall

     treasury bills, so called "sweep" accounts, and other investments;

          (g)  to negotiate, enter into, execute, acknowledge and deliver all
     contracts, agreements, documents and instruments appropriate to carry on
     the business of the Partnership, including granting the commodity trading
     advisor or advisors a power of attorney to effect trades on behalf of the
     Partnership on a discretionary basis and without notice to the General
     Partner or any Limited Partners, and subscription agreements for Units;

          (h)  to cause to be paid all taxes, charges and assessments that are
     levied, assessed or imposed upon any of the assets of the Partnership,
     unless the same are contested in good faith by the General Partner;

     within the meaning of this Section 5.03(e).

     5.04  Right of Public to Rely on Authority of General Partner.  No person
           --------------------------------------------------------
shall be required to determine the General Partner's authority to make or incur
any undertaking on behalf of the Partnership, or to see to the application or
distribution of revenues or proceeds paid to the General Partner.

     5.05  Obligations of General Partner; Partners' Interests in Other
           ------------------------------------------------------------
Business. The General Partner shall devote such time and effort to the
- ---------
Partnership's business as is necessary or appropriate to manage the affairs of
the Partnership. It is specifically understood and agreed, however, that no
Partner (including the General Partner) shall be required to devote full time to
the Partnership's business and that any Partner (including the General Partner)
may engage in and possess interests in other business ventures, including
ventures which are competitive with the Partnership; and neither the Partnership
nor any Partner shall by virtue of this Agreement have any right, title or
interest in or to such ventures.

     5.06  Liability of the General Partner; Indemnification.  The General
           --------------------------------------------------
Partner shall not be liable, responsible or accountable in damages or otherwise
to the Partnership or any of the Limited Partners for any act or omission
performed or

                                       7
<PAGE>
 
omitted by the General Partner in good faith on behalf of the Partnership and in
a manner reasonably believed by the General Partner to be within the scope of
authority granted by this Agreement and in, or not opposed to, the best
interests of the Partnership, except only when such action or failure to act
constitutes negligence or misconduct.

     The Partnership shall defend, indemnify and hold the General Partner
harmless from and against any loss, liability, damage, cost or expense
(including court costs, arbitration costs, and attorneys' and accountants' fees
and expenses) actually and reasonably incurred by the General Partner and
arising from any act, omission, activity or conduct undertaken by or on behalf
of the Partnership and reasonably believed by the General Partner to be within
the scope of authority conferred by this Agreement, including against any
demands, claims, lawsuits, arbitration proceedings or other actions initiated by
a Limited Partner; provided, however, that such indemnity shall be payable only
if the General Partner (a) acted in good faith and in a manner the General
Partner reasonably believed to be in, or not opposed to, the best interests of
the Partnership, and (b) the act, omission, activity or conduct in question did
not constitute negligence or misconduct. No indemnification may be made,
however, with respect to any losses, liabilities, damages, costs or expenses
arising from or out of an alleged violation of federal or state securities laws
unless (i) there has been a successful adjudication on the merits of each count
involving alleged securities law violations as to the particular indemnitee, or
(ii) such claim has been dismissed by a court with prejudice on the merits as to
the particular indemnitee, or (iii) a court approves a settlement of the claims
against the particular indemnitee and finds that indemnification of the
settlement and related costs and expenses should be made, provided the
indemnitee must apprise the court of the position of the SEC and of the
securities administrator of the state in which the plaintiffs claim they were
offered or sold Units with respect to indemnification for securities laws
violations before seeking court approval for indemnification.

     The General Partner shall in no event be liable to the Partnership or any
Limited Partner because any taxing authority disallows or adjusts any deductions
or credits in the Partnership's or any Limited Partners' income tax returns. The
General Partner shall also in no event be liable for the return or repayment of
the Capital Contributions or profits of any Partner, with any return or
repayment of capital or profits to be made solely from the assets of the
Partnership (which shall not include any right of contribution from the General
Partner).

     The Partnership shall make advances of costs and expenses to the General
Partner and the General Partner's affiliates (as that term is defined in Section
12.06 below) with respect to any demand, claim, proceeding, lawsuit or action,
but only if (i) it relates to acts or omissions with respect to the performance
of duties or services on behalf of the Partnership; (ii) it is initiated by a
third party who is not a Limited Partner or it is initiated by a Limited Partner
and a court specifically approves such advancement; and (iii) the General
Partner or the General Partner's affiliate, as the case may be, undertakes to
repay the advanced funds to the Partnership, together with interest at the legal
rate under Iowa law, if the General Partner or the affiliate is ultimately found
not to be entitled to indemnification hereunder.
 
     The provisions of this Section 5.06 shall not be affected by the
termination of the Partnership or the resignation, removal, death, withdrawal,
insolvency or dissolution of the General Partner.

     All of the provisions of this Section 5.06 shall apply to affiliates of the
General Partner when such affiliates are performing services on behalf of the
Partnership.

     Any indemnity under this Section 5.06 shall be paid from, and only to the
extent of, Partnership assets, and no Limited Partner shall have any personal
liability for the payment of any such indemnity. The Partnership shall not incur
the cost of that portion of liability insurance, if any, which insures the
General Partner for any liability for which indemnification is not allowed under
this Section 5.06.

     5.07  Compensation and Reimbursement of the General Partner.
           ------------------------------------------------------

     (a)  The General Partner shall be paid a quarterly incentive fee of 15% of
the New Trading Profits (as that term is defined below) of the Partnership for
each quarter, if any. "New Trading Profits" means the excess, if any, of the Net
Assets of the Partnership at the end of each respective quarter over the highest
Net Assets of the Partnership at the end of any previous quarter or on the date
trading commences, whichever is higher. Net Assets shall be adjusted for this
purpose to eliminate the effect thereon resulting from new Capital Contributions
or distributions or liquidations made during the quarter, and shall be decreased
by any interest or other income earned on Partnership assets during the quarter
which is not directly related to trading activity and whether such assets are
held separately or in a margin account. Also, Net Assets shall be determined
excluding accrual of the incentive fee (if any), but including accrual of the
management fee for the months comprising the quarter in question, as the
management fee is calculated pursuant to Section 5.07(b) below. In addition, if
the Partnership incurs a net loss during any quarter, such loss shall be carried
over and charged against the Net Assets of the succeeding quarters until such
loss has been exhausted and before any further incentive fees shall be paid to
the General Partner. The incentive fee shall be payable as soon as is reasonably
practicable following the close of each quarter.

     (b)  The General Partner shall also be paid a monthly management fee of 
one-half of one percent (0.5%) [which equates to 6% annually] of the
Partnership's Net Assets as of the close of business on the last business day of
each month. Net Assets for this purpose shall be determined before accrual of
both the management fee and the incentive fee contemplated by Section 5.07(a)
above. The management fee shall be paid by the Partnership within ten (10)
business days of the close of each month.

     (c)  The General Partner shall be entitled to reimbursement from the
Partnership for all Partnership obligations or expenses which are paid or
incurred by the General Partner.

     5.08  Fiduciary Responsibility.  The General Partner shall have a fiduciary
           -------------------------
responsibility for the safekeeping and use of all funds and assets of the
Partnership.

     5.09  Resignation or Withdrawal of General Partner; Admission of Additional
           ---------------------------------------------------------------------
General Partners.  The General Partner may resign or withdraw from the
- -----------------
Partnership as General Partner upon (i) the affirmative vote of the Limited
Partners who possess at least a Majority in Interest, and (ii) if there is not
then another general partner for the Partnership, providing a successor general
partner(s) satisfactory to the Limited Partners who possess at least a Majority
in Interest. The General Partner may not otherwise voluntarily resign or
withdraw from the Partnership as general partner except upon the giving of at
least one hundred twenty (120) days prior written notice to the Limited
Partners. In the latter event, the General Partner shall pay all reasonable
expenses incurred as a result of the General Partner's withdrawal if there is
not then another general partner and the Limited Partners elect to carry on the
business of the Partnership by a substituted general partner(s) in accordance
with Section 9.03 below. Any resignation or withdrawal by the General Partner in
accordance with this Section 5.09 shall not violate or constitute a breach of
this Agreement and shall not give rise to or create any claim for damages in the
Partnership or any of the Partners. No resignation or withdrawal of the General
Partner, whether voluntary, involuntary or by operation of law, shall relieve
the General Partner of any obligation up to the date of withdrawal, except with
the express written consent of the Limited Partners who possess at least a
Majority in Interest.

     Any other person(s) may be admitted as additional general partners of the
Partnership upon the written consent or vote of the Limited Partners who possess
at least a Majority in Interest. Any such additional general partner(s) shall be
permitted to continue and carry on the business of the Partnership following the
withdrawal, for whatever reason, of any other general partner of the
Partnership. Written notice of the admission of any additional general partner
shall be given to the Limited Partners who did not consent to such admission
within ten (10) business days of such admission. In the event there is more than
one general partner for the Partnership, all of such general partners shall have
all of the rights, duties and obligations of the General Partner as set forth in
this Agreement, and any decisions to be made by such general partners shall be
made by a majority vote of such general partners.

            ARTICLE VI: Rights and Obligations of Limited Partners

     6.01  Limitations on Limited Partners.  No Limited Partner shall: (a)
           --------------------------------
participate in the control of the business of the Partnership; (b) have any
voice in the management or operation of any Partnership property; (c) have the
authority or power to bind or act as agent for or on behalf of the Partnership
or any other Partner, or to incur any expenditures on behalf of the Partnership;
or (d) withdraw from the Partnership except in accordance with Section 4.03
above.

     6.02  Liability of Limited Partners.  No assessments of any kind shall be
           ------------------------------
made against any of the Limited Partners. In addition, so long as such Limited
Partner complies with the provisions of Section 6.01 above, the liability of
each Limited Partner for the losses, debts and obligations of the Partnership
shall be limited to the Limited Partner's Capital Contribution and share of any
undistributed assets of the Partnership; provided, however, that under the Act
(i) if a Limited Partner has received the return of any part of the Limited
Partner's Capital Contribution without violation of this Agreement or the Act,
for one (1) year after the return, the Limited Partner is liable to the
Partnership for the amount of the returned contribution to the extent necessary
to discharge the Partnership's liabilities to creditors who extended credit to
the Partnership during the period the contribution was held by the Partnership,
and (ii) if a Limited Partner has received the return of any part of the Limited
Partner's Capital Contribution in violation of this Agreement or the Act, for
six (6) years after the return, the Limited Partner is liable to the Partnership
for the amount of the contribution wrongfully returned.

     6.03  Meetings; Vote; Voting Rights.
           ------------------------------

     (a)  A meeting of the Limited Partners may be called by the General Partner
at any time and for any purpose, and shall be called by the General Partner no
more than fifteen (15) days after receipt by the General Partner of a written
request for such a meeting setting forth the purpose thereof, and signed by
Limited Partners who collectively own at least ten percent (10%) of the then
outstanding Units. The General Partner shall give written notice of any meeting
and the purpose thereof to all Limited Partners. Any such meeting shall be held
at a reasonable time and place (which includes the Partnership's principal
office) on a date no less than thirty (30) nor more than sixty (60) days after
the date of the General Partner's written notice of the meeting.

     (b)  Any action required or permitted to be taken by Limited Partners at a
meeting may be taken without a meeting, prior notice, or a vote, if a consent in
writing setting forth the action taken is signed by the Limited Partners owning
Units having not fewer than the minimum number of votes otherwise necessary to
take such action under this Agreement. Written notice of the taking of action
under this Section 6.03(b) shall be given to those Limited Partners who did not
consent to such action. All written consents shall be treated for all purposes
as votes at a meeting.

     (c)  Each Limited Partner shall be entitled to one (1) vote for each
outstanding whole Unit owned by such Limited Partner, and to a fractional vote
in an amount equal to any fractional Unit owned by such Limited Partner. All
actions of the Limited Partners taken at any meeting or by written action
without a meeting shall require the affirmative vote of the Limited Partners
holding at least a majority of the total number of outstanding Units ("a
Majority in Interest"), unless a higher vote is affirmatively required by any
other provision of this Agreement or by the Act. Partners may vote in person or
by proxy.

     (d)  The Limited Partners who possess at least a Majority in Interest may,
to the extent permitted by law, and without the concurrence of the General
Partner (except as provided below), vote to (i) amend this Agreement and, if
necessary, the Certificate; (ii) remove the General Partner and elect a new
general partner(s); and (iii) cancel any contract for services with the General
Partner without penalty upon sixty (60) days prior written notice. Provided,
however, that any amendment of this Agreement pursuant to this Section 6.03
which modifies the compensation or distributions to which the General Partner is
entitled or which affects the duties or obligations or the rights or protections
of the General Partner shall be conditioned upon the consent of the General
Partner, which may be withheld in the General Partner's sole discretion. In the
event of the removal of the General Partner by the Limited Partners pursuant to
this Section 6.03, the General Partner shall be entitled to a liquidation of any
or all of the General Partner's Units at the Net Asset Value Per Unit on and as
of the opening of trading on the first business day of the month next following

                                       10
<PAGE>
 
the date on which the General Partner is removed. If the General Partner does
not liquidate all of its Units at such time, the General Partner shall
thereafter be entitled to a liquidation of its Units in accordance with Section
4.03 above.

     7.01 Books and Records.  The General Partner shall keep true books of
          -----------------
account and records with respect to the operations of the Partnership, including
those books and records as may be required under the CFTC's regulations. Such
books and records shall be maintained at the Partnership's principal place of
business, and all Partners, and their duly authorized representatives, shall at
all reasonable times have access to such books and records. The General Partner
shall maintain and preserve such books and records for a period of not less than
five (5) years.

otherwise determined by the General Partner, in the General Partner's sole
discretion; (ii) shall reflect all Partnership transactions, (iii) shall be
appropriate and adequate for the Partnership's business and to carry out the
provisions of this Agreement, and (iv) shall be closed and balanced at the end
of each fiscal year of the Partnership. The fiscal year of the Partnership shall
be the calendar year.

     7.03 Reports.  The General Partner shall cause such reports or information
          -------
to be provided to the Partners as the CFTC, the NFA, the SEC, the NASD or any
other applicable governmental authority may from time to time require to be
given to the Partners.

     The General Partner shall also provide to all Partners, by not later than
March 15 of each year, all information with respect to the Partnership which is
necessary for the preparation of the Partners' respective income tax returns.

     The General Partner shall calculate the Net Assets of the Partnership on a
daily basis, and shall promptly advise a Partner, upon request, of the Net Asset
Value Per Unit as of the time of the request.

     7.04  Notices.
           -------

     (a)  The General Partner shall cause a notice to be given to each Partner
within seven (7) business days from the date of: (i) the date (the "Decline
Date") upon which there shall have been a decline in the Net Asset Value Per
Unit to less than fifty percent (50%) of the Net Asset Value Per Unit as of the
close of business on the day which is one year prior to the Decline Date; (ii)
any material change in contracts with any of the Partnership's commodity trading
advisors, including any change in commodity trading advisors or any modification
in the method of calculating any incentive fee which may be payable by the
Partnership to any commodity trading advisor; and (iii) any other material
change affecting the compensation of any party which is payable by the
Partnership. In the case of a notice given pursuant to subclause (i) above, the
Limited Partners will have the opportunity to request the liquidation of their
Units as provided in Section 4.03(e) above.

     (b)  The General Partner shall also cause a notice to be given to each
Partner prior to effecting any material change related to brokerage commissions.
Any such change shall not be made for 30 calendar days, during which time the
Partners will have the right to request liquidation of their Units pursuant to
Section 4.03 above.

     (c)  Any notification pursuant to this Section 7.04 shall include a
description of the Partner's liquidation rights and voting rights, if any, and a
description of any material effect the changes specified in the notice may have
on the interests of the Partners. Any notice given pursuant to Section
7.04(a)(i) above shall also include the following, in capital letters and bold
face print: "A LIMITED PARTNER SHOULD OBTAIN ADVICE FROM AN INDEPENDENT
INVESTMENT AND PROFESSIONAL ADVISOR AS TO WHETHER THE LIMITED PARTNER SHOULD
REQUEST LIQUIDATION OF THE LIMITED PARTNER'S UNITS BECAUSE OF THE DECLINE IN THE
NET ASSET VALUE PER UNIT."

<PAGE>
 
     7.05 Bank Accounts.  The General Partner shall establish one or more bank
          -------------
accounts to be used for the payment of the expenditures of the Partnership. All
such accounts shall be the property of the Partnership, and shall be used only
for Partnership purposes. Only Partnership funds shall be deposited in said
accounts.

     7.06 Tax Returns.  The General Partner shall cause Partnership tax returns
          -----------
to be prepared and timely filed, and shall also cause the Partnership to pay any
taxes payable by the Partnership. The General Partner is not, however, required
to cause the Partnership to pay any tax so long as the General Partner or the
Partnership is in good faith and by appropriate means contesting the
applicability, validity or amount thereof and such contest shall not materially
endanger any right or interest of the Partnership.

     7.07 Tax Elections.  The General Partner will make all tax elections or
          -------------
allocations deemed necessary or desirable for the Partnership or the purposes of
this Agreement. Without limiting the preceding sentence, the General Partner is

the Partnership in all audits and other administrative proceedings; (ii) the
power to extend the statute of limitations for all Limited Partners; (iii) the
power to file a petition with an appropriate federal court for a review of a
final Partnership administrative adjustment; and (iv) the power to enter into a
settlement with the Internal Revenue Service (the "IRS") on behalf of, and
binding upon, those Limited Partners having less than a one percent (1%)
interest in the Partnership, unless a Limited Partner has notified the IRS and
the General Partner to the contrary.

       ARTICLE VIII: Assignability of Units; Additional Limited Partners

     8.01 Assignment of a Limited Partner's Units.
          ---------------------------------------

     (a)  Except as otherwise provided below, a Limited Partner may not sell,
transfer, assign, hypothecate, pledge, or otherwise dispose of any Unit (whether
voluntarily, involuntarily or by operation of law) unless and until all of the
following conditions have been satisfied, except that the General Partner may,
in its sole discretion, waive any one or more of the conditions specified in
subclauses (ii) and (iv) below:

          (i)  the assignor and the assignee shall have delivered a written
     instrument of assignment and assumption in a form satisfactory to the
     General Partner;

          (ii)  after the assignment, neither the assignee nor the assignor, if
     the assignor has retained any part of a Unit, shall hold Units that
     represent less than the minimum initial investment in the Partnership as
     then established by the General Partner, except for transfers by gift,
     inheritance, intra family transfers, family dissolutions, and transfers to
     affiliates;

          (iii)  the General Partner shall have consented in writing to the
     assignment, which consent shall be granted if the other conditions are met
     (or have been waived by the General Partner) and in the opinion of the
     Partnership's counsel such assignment (1) may be effected without
     registration under any applicable securities laws; (2) will not violate any
     applicable laws or governmental rules or regulations, including securities
     laws or limited partnership laws; and (3) will not jeopardize the status
     of, or cause a termination of, the Partnership or the Partnership's tax
     year for federal income tax purposes nor affect the characterizations or
     treatment of income or loss; and

          (iv)  the assignee agrees to pay all reasonable expenses incurred in
     connection with the assignment, including attorneys' fees.

     The Partnership shall not be required to recognize any assignment of any
Unit until the effective date of such assignment. Unless and until an assignee
becomes a substituted Limited Partner in accordance with Section 8.03 below, the
assignee shall only have the right to receive the share of the profits, losses,
distributions and returns of capital

                                       12
<PAGE>
 
(including pursuant to a liquidation of Units in accordance with Section 4.03
above) to which the assignor would be otherwise entitled to with respect to the
assigned Units.

     By executing or otherwise adopting this Agreement, each Limited Partner
shall be deemed to have consented to any assignment of a Unit consented to by
the General Partner.

     (b)  The Partnership and the General Partner shall be entitled to treat the
record owner of any Units (as shown on the books of the Partnership) as the
absolute owner thereof for all purposes, and shall incur no liability for
distributions made to such owner.

     (c)  Each Limited Partner shall, in connection with the assignment of any
Unit, and upon the request of the General Partner, execute such documents and
perform such other acts as the General Partner deems appropriate to preserve the
limited liability status of the Partnership.

     (d)  A Limited Partner ceases to be a limited partner for all purposes upon
assignment of all of the Limited Partner's Units. No assignment shall, however,
relieve a Limited Partner of any obligation under this Agreement without the
express written consent of the General Partner.

     (e)  Any purported assignment of a Unit which is not made in compliance
with this Agreement is null and void and of no force and effect whatsoever. For
purposes of this Section 8.01, any transfer of a Unit in the Partnership shall
be considered an assignment, whether the transfer is voluntary, involuntary, or
by operation of law.

     8.02  Assignee's Rights.  An assignee of a Unit shall be entitled to
           -----------------
receive distributions and to receive allocations of the profits and losses of
the Partnership attributable to such Unit after the effective date of the
assignment. The "effective date" of an assignment of a Unit under this Section
8.02 and Section 8.01 above shall be the date designated in the written
instrument whereby the General Partner consents to the assignment, which date
shall be not later than (but may in the sole discretion of the General Partner
be prior to) the first business day of the month next following the date on
which all conditions precedent to such assignment have been satisfied.

     8.03  Substituted Limited Partner.  Each Limited Partner shall have the
           ---------------------------
right to allow and cause an assignee of any of the Limited Partner's Units to
become a substituted Limited Partner with respect to those Units in the place of
such assigning Limited Partner, without the consent of the General Partner or
any of the other Partners. Any assignment effectuated in accordance with Section
8.01 above shall be deemed to cause the assignee to be a substituted Limited
Partner with respect to the assigned Units unless otherwise designated by the
assignor. In addition, and notwithstanding any reservations or objections of the
assignor of the Units, an assignee of any Units may be substituted as a Limited
Partner as to such Units upon and with the consent or vote of all of the
Partners, other than the assignor of the Units. By executing or adopting this
Agreement, each Limited Partner shall be deemed to have consented to any
substitution of an assignee of any Units in the place of the assignor.

     8.04  Substitution Required for Vote.  Unless and until an assignee of a
           ------------------------------
Unit becomes a substituted Limited Partner, the assignee shall not be entitled
to exercise any vote with respect to such Unit or otherwise have any rights of a
Limited Partner, except only as provided in Sections 8.01 and 8.02 above.

     8.05  Effective Date of Substitution.  The effective date of a substitution
           ------------------------------
of an assignee of a Unit made by the assignor shall be the effective date
specified in Section 8.02 above if the substitution is made at the time of the
assignment of the Unit, or upon receipt by the General Partner of written notice
thereof from the assignor if made at a later time. The effective date of a
substitution of an assignee of a Unit made pursuant to the consent or vote of
all of the other Partners pursuant to Section 8.03 above shall be the date upon
which the requisite consent or vote has been obtained.

     8.06  Additional Limited Partners; Additional Contributions by Existing
           -----------------------------------------------------------------
Partners.  The General Partner shall have the right to admit additional Limited
- --------
Partners to the Partnership and to accept additional Capital Contributions from
existing Partners. Additional Limited Partners shall be admitted to the
Partnership effective on and as of the opening of trading on the first business
day of the month next following the date on which the General Partner accepts a
duly executed subscription

                                       13
<PAGE>
 
agreement and the required applicable capital contribution from the Limited
Partner in question. By executing or otherwise adopting this Agreement, each
Limited Partner shall be deemed to have consented to the admission of all
additional Limited Partners admitted to the Partnership by the General Partner.
Additional Capital Contributions from existing Partners shall be in such amount
as is acceptable to the General Partner, in its sole discretion, and shall be
effective on and as of the opening of trading on the first business day of the
month next following the date of the General Partner's acceptance of the
additional Capital Contribution in question.

     8.07  Bankruptcy, Death, Incapacity, Etc. of Limited Partner.  The
           ------------------------------------------------------
withdrawal, insolvency, bankruptcy, termination, liquidation, dissolution, death
or other legal incapacity of a Limited Partner shall not cause a dissolution of
the Partnership. The rights of such a Limited Partner to share in the profits
and losses of the Partnership, to receive distributions of Partnership funds, to
assign such Limited Partner's Units and cause the substitution of a substituted
Limited Partner with respect to such Units, and to vote such Units shall, on the
happening of such an event, devolve on such Limited Partner's estate, trustee,
custodian, personal representative, or in the event of the death of one whose
Unit is held in joint tenancy, pass to the surviving joint tenant, in each case
subject to the terms and conditions of this Agreement. The estate of a deceased
or incapacitated Limited Partner shall be liable for all of the obligations of
such Limited Partner.

                    ARTICLE IX: Dissolution and Termination

     9.01 Events of Dissolution.
          ---------------------

     (a)  The Partnership shall be dissolved and its affairs shall be wound up:

          (i)  upon the occurrence of an event specified under the Act as one
     causing or effecting dissolution (subject to any right to reinstate the
     Partnership as may be provided under the Act);

          (ii)  upon the election of the General Partner, in the General
     Partner's sole discretion, to terminate and dissolve the Partnership;

          (iii)  upon the General Partner withdrawing as or otherwise ceasing to
     be the general partner of the Partnership, whether by reason of an act or
     circumstance contemplated by this Agreement or the Act, unless at the time
     there is at least one other general partner and such remaining general
     partner continues and carries on the business of the Partnership or unless
     the Limited Partners shall elect to carry on the business of the
     Partnership pursuant to Section 9.03 below;

          (iv)  upon the affirmative vote of the Limited Partners who
     collectively hold at least a Majority in Interest; or

          (v)  in any event, at 11:59 p.m. on December 31, 2050.

          (b)  The dissolution of the Partnership shall be effective on the day
     on which the event giving rise to the dissolution occurs. The Partnership
     shall not terminate, however, until the Certificate has been canceled and
     the assets of the Partnership have been distributed as provided herein, and
     the business of the Partnership and the affairs of the Partners shall
     continue to be governed by this Agreement until the termination of the
     Partnership. Upon dissolution, the General Partner, or if there be none, a
     liquidator appointed by the Limited Partners who collectively hold at least
     a Majority in Interest, shall liquidate the assets of the Partnership,
     apply and distribute the proceeds thereof as provided by this Agreement and
     cause the cancellation of the Certificate.

     9.02 Distributions Upon Liquidation.
          ------------------------------

          (a)  After payment of liabilities owing to creditors (including, to
     the extent permitted by law, to Partners who are creditors), the General
     Partner or liquidator, as the case may be, shall set up such reserves as it
     deems reasonably necessary for any contingent or unforeseen liabilities or
     obligations of the Partnership. The reserves may

                                       14
<PAGE>
 
     be paid over and held in escrow in a bank account for the purpose of paying
     any contingent or unforeseen liabilities or obligations, and at the
     expiration of such period as the General Partner or liquidator may deem
     advisable, such reserves shall be distributed to the Partners in the manner
     set forth in Section 9.02(b) below.

          (b)  After paying such liabilities and providing for such reserves,
     the General Partner or liquidator, as the case may be, shall cause the
     remaining assets of the Partnership to be distributed to the Partners in
     the proportion that the capital account of each Partner bears to the total
     capital account of all Partners. If those distributions are insufficient to
     return the full amount of any Partner's Capital Contribution, such Partner
     shall have no recourse against any other Partner; provided, however, that
     this provision shall not be interpreted as a waiver by any Partner of any
     rights under existing and future laws regarding fiduciary duties of the
     General Partner.

     9.03  Election to Carry on Business.  In the event of the withdrawal of the
           -----------------------------
General Partner or the General Partner otherwise ceasing to be the General
Partner, the Limited Partners may, within ninety (90) days of such event, elect
to carry on the business of the Partnership with one or more substituted general
partner(s) by the unanimous affirmative vote of all Limited Partners.

             ARTICLE X: Miscellaneous Restrictions on Partnership 
                         Relationships and Activities

     The following relationships or activities are prohibited or restricted, as
the case may be, as follows:

          (a)  The Partnership shall not make any loans to the General Partner
     or any other person.

          (b)  The General Partner shall not receive any rebates or giveups nor
     participate in any reciprocal business arrangements which circumvent the
     restrictions set forth in this Article X and those against dealing with
     affiliates or other interested parties.

          (c)  Neither the Partnership's commodity trading advisor nor any other
     person acting in such capacity shall receive a management fee or an
     advisory fee (which terms do not include an incentive fee) if such person
     shares or participates, directly or indirectly, in any brokerage
     commissions generated by the Partnership.

          (d)  The term of any contract between the Partnership and the
     Partnership's commodity trading advisor or General Partner shall not exceed
     one year and any such contract must be terminable without penalty upon
     sixty (60) days written notice by the Partnership; provided, however, that
     any such contract may provide for a continuous term or renewable terms so
     long as such contract is otherwise terminable upon thirty (30) days or less
     written notice by the Partnership.

          (e)  The Partnership shall not engage in pyramiding, which means using
     all or a part of an unrealized profit in a futures contract position to
     provide margin for any additional futures contracts of the same or related
     commodities; provided, however, that taking into account the Partnership's
     open trade equity on existing positions in determining generally whether to
     acquire additional positions on behalf of the Partnership will not be
     considered to constitute "pyramiding."

          (f)  All expenses of the Partnership shall be billed directly to and
     paid by the Partnership or reimbursed to others upon receipt of
     satisfactory evidence of payment.

          (g)  Neither the General Partner nor any affiliate of the General
     Partner may receive interest, points or other financing charges on any loan
     made by them to the Partnership.

          (h)  Any subscription agreement executed by a Limited Partner in
     connection with the purchase of Units shall be retained by the General
     Partner for 6 years.

                                       15
<PAGE>
 
          (i)  The funds of the Partnership shall not be commingled with the
     funds of the General Partner; provided, however, without limitation, that
     funds used to satisfy margin requirements will not be considered
     commingled.

          (j)  The Partnership shall not permit "churning" of the Partnership's
     assets.

     11.01  Amendments Proposed.  Amendments to this Agreement may be proposed
            -------------------
by the General Partner by the General Partner giving a written notice of the
proposed amendment to the Limited Partners. Each such notice shall state that
the proposed amendment shall become effective thirty (30) days after the mailing
of such notice, unless Limited Partners holding ten percent (10%) or more of the
then outstanding Units shall object in writing to the General Partner prior to
that date. In the event of such objection, the matter may be resubmitted to the
Limited Partners in accordance with Section 6.03 above.

     11.02  Amendments by General Partner.
            -----------------------------

          (a)  Additions, deletions, amendments or other modifications may be
     made to this Agreement and the Certificate by the General Partner without
     the consent or approval of the Limited Partners: (i) to add to the duties
     or obligations of or surrender any right or power granted to the General
     Partner; (ii) to change the name of the Partnership; (iii) to cure any
     ambiguity, to correct or supplement any inconsistent provisions, or to make
     any other provisions which will not be inconsistent with the provisions of
     this Agreement; (iv) to delete any provision of, add any provision to, or
     amend or modify any provision of this Agreement as suggested by the CFTC,
     the NFA, the SEC, the NASD, a state securities commissioner or similar such
     official, or by any other domestic or foreign governmental authority; (v)
     to attempt to ensure that the Partnership is not taxed as a corporation or
     to effect the intent of the allocations herein to the maximum extent
     possible in the event of a change in applicable laws affecting such
     allocations; (vi) to prevent the Partnership or the General Partner or its
     affiliates from being subject to the provisions of the United States
     Investment Company Act of 1940, the United States Investment Advisers Act
     of 1940, or regulations adopted under the United States Employee Retirement
     Income Security Act of 1974, as amended, or any successor legislation;
     (vii) to qualify the Partnership under the United States Investment Company
     Act of 1940 and any persons under the United States Investment Company Act
     of 1940 or the United States Investment Advisers Act of 1940, as amended,
     or any successor legislation to any of the foregoing; (viii) to qualify or
     maintain the qualification of the Partnership as a limited partnership in

     or changes in the Act and/or applicable tax laws, rules, regulations,
     rulings, procedures, orders, interpretive notices or otherwise; (x) to
     effectuate Section 12.05 below; and (xi) to reflect the admission or
     withdrawal of additional or substitute general partners. Provided, however,
     that no amendment shall be adopted pursuant to this Section 11.02(a) unless
     the adoption thereof (1) is not materially adverse to the interests of the
     Limited Partners, (2) is consistent with Section 5.01 above, (3) does not
     affect the distributions provided in Article IV above or the allocation of
     profits or losses provided in Article III above, and (4) does not affect
     the limited liability of the Limited Partners contemplated by Section 6.02
     above or the status of the Partnership as a partnership for federal income
     tax purposes. The power of attorney granted pursuant to Section 12.03 below
     and pursuant to any subscription agreement given by a Limited Partner may
     be used by the General Partner to execute on behalf of a Limited Partner
     any document evidencing an amendment adopted in accordance with the terms
     of this Section 11.02(a).

          (b)  The General Partner shall provide the Limited Partners with a
     copy of any amendment adopted pursuant to this Section 11.02.

Partnership Agreement, as amended to date and as may be amended from time to
time (the "Partnership Agreement").

     2.   SUBSCRIPTION.  Subscriber agrees to purchase units of limited
          ------------
partnership interest in the Partnership ("Units") equal to the dollar amount set
forth on the signature page hereto in accordance with and on the terms and
conditions set forth in this Subscription Agreement and in the Partnership's

Prospectus. Capitalized terms not otherwise defined herein shall have the
meanings given them in the Prospectus.

     The purchase price per Unit prior to the commencement of trading by the
Partnership is $1,000. The purchase price per Unit after that time shall be the
Net Asset Value Per Unit as of the opening of trading on the effective date of
the purchase, which will be the first business day of the month next following

subscriber or subscribers. Subsequent investments by existing Limited Partners
in the Partnership may be in such amounts as may be accepted by the General
Partner from time to time, in the General Partner's sole discretion.

     3.   PAYMENT AND DELIVERY OF DOCUMENTS.  Prior to the release of
          ---------------------------------
subscription payments from escrow as described in Section 4 below, Subscriber
shall tender to Portfolio Boost, L.L.C., an Iowa limited liability company
serving as the general partner of the Partnership (the "General Partner"),
Subscriber's check in the dollar amount set forth on the signature page hereto
made payable to "First American Bank--Escrow Agent for PB III." Following the
release of subscription payments from escrow, Subscriber shall tender to the
General Partner Subscriber's check in the dollar amount set forth on the
signature page hereto made payable to "Portfolio Boost III, L.P." Payment of the
dollar amount set forth on the signature page hereto shall constitute
Subscriber's capital contribution to the Partnership.

     The executed signature page to this Agreement and Subscriber's payment
should be forwarded to the Partnership at the address set forth in the
Prospectus. Subscriber shall also forward the other Subscription Documents (as
that term is defined in the Prospectus) to that address. Subscriber acknowledges
that the General Partner or Vacation Investors, Inc. (the "Underwriter") may
request additional information from Subscriber in connection with this
subscription.

     4.   ESCROW ACCOUNT.  Subscription payments will initially be deposited and
          --------------
held in a separate escrow account at First American Bank, Fort Dodge, Iowa,
pending receipt, acceptance and collection of subscriptions totaling $500,000.
Subscription payments deposited in the escrow account may not be withdrawn by
Subscriber under any circumstances. If subscriptions totaling $500,000 are not
received and accepted within nine (9) months of the date of the initial
Prospectus utilized by the Partnership in offering its units of limited
partnership interest, the Partnership will terminate the offering and all
amounts paid by Subscriber will be returned to Subscriber within ten (10)
business days of the close of said nine (9) month period, without deduction and
together with Subscriber's pro rata share of all amounts earned in excess of the
subscriptions received, if any. If subscriptions for $500,000 are received and
accepted by the designated date, the escrowed funds (including all earnings
thereon) will be released to the Partnership, and the Partnership shall
thereafter commence trading at such time as is determined by the Commodity
Trading Advisor for the Partnership.

     No escrow will be utilized for subscriptions received and accepted
following the release of funds from escrow to the Partnership as provided above.

     5.   ACCEPTANCE OR REJECTION OF SUBSCRIPTION.  Subscriber acknowledges and
          ---------------------------------------
agrees that this subscription shall not be effective until accepted in writing
by the General Partner and that the General Partner reserves the right to reject
this subscription in whole or in part. Subscriptions may be rejected for failure
to conform to the requirements of the offering, insufficient documentation,
oversubscription of the offering or for such other reason or reasons as the
General Partner may determine, in its sole discretion. In the event of rejection
of this subscription in whole, Subscriber's payment will promptly be returned to
Subscriber without deduction and this Subscription Agreement shall have no
further force or effect. In the event of rejection of this subscription in part,
the rejected amount of Subscriber's payment will be promptly returned to
Subscriber, but

                                       2
<PAGE>
 
in that circumstance this Subscription Agreement shall remain in full force and
effect. Subscriber shall not be entitled to receive any interest or other
earnings on Subscriber's subscription in the event of rejection of this
subscription, in whole or in part, by the General Partner.

     6.   ADMISSION TO PARTNERSHIP.  In the event Subscriber's subscription is
          ------------------------
accepted by the General Partner and the minimum offering contingency specified
in Section 4 above is satisfied, Subscriber shall be admitted to the Partnership
as a Limited Partner in accordance with the following:

     establish or otherwise evidence or substantiate compliance with the
     requirements of the Partnership's offering, this Subscription Agreement or
     federal or state securities laws or regulations, including, without
     limitation, a purchaser questionnaire, financial statements of Subscriber
     and a letter from Subscriber justifying the suitability of Subscriber's
     investment in the Partnership and containing such additional disclosures
     and additional representations and warranties from Subscriber as the
     General Partner determines to be necessary or appropriate to establish or
     otherwise evidence or substantiate compliance with the requirements of the
     Partnership's offering, this Subscription Agreement or any federal or state
     securities laws or regulations. All such additional information and
     documentation will be true and accurate in all respects.

          (e)  The General Partner shall have the right to accept or reject
     Subscriber's subscription in whole or in part. Subscriptions may be
     rejected for, without limitation, failure to conform to the requirements of
     the Partnership's offering, insufficient documentation, oversubscription of
     the offering, or for any such other reason as the General Partner may
     determine, in its sole discretion.

          (f)  Subscriber has received and carefully read and is familiar with
     the Prospectus (including, without limitation, the sections in the
     Prospectus setting forth the risk factors and conflicts of interest
     applicable to an investment in the Partnership and the fees payable by the
     Partnership to the General Partner and others), the Partnership Agreement
     and this Subscription Agreement, and confirms that all documents
     incorporated in the Prospectus and all records and books pertaining to the
     investment in the Units made pursuant to this Subscription Agreement have
     been made available to Subscriber.

          (g)  Subscriber has had access, during the course of this transaction
     and prior to sale, to all information necessary to enable Subscriber to
     evaluate the merits and risks of a prospective investment in Units and the
     Partnership, and Subscriber has had the opportunity to ask questions of and
     receive answers from the General Partner, or a person or persons acting on
     the General Partner's behalf, concerning the terms and conditions of the
     offering and the opportunity to obtain any additional information which the
     Partnership or the General Partner possesses or can acquire without
     unreasonable effort or expense that is necessary to verify the accuracy of
     the information contained in and incorporated in the Prospectus or to which
     Subscriber has had access; and all questions raised by Subscriber have been
     answered to the full satisfaction of Subscriber.

                                       4

          (h)  Subscriber (i) is acquiring the Units for Subscriber's own
     account for investment only and not with a view to the distribution, resale
     or transfer thereof, and as the sole record and beneficial holder thereof,
     (ii) is acquiring such Units without any intention of reselling or
     distributing any of such Units except in accordance with the provisions of
     the Securities Act of 1933 (the "Act") and rules and regulations
     promulgated thereunder and applicable state securities laws and regulations
     and with the provisions of the Partnership Agreement, and (iii) agrees that
     the Units shall not be sold, pledged, hypothecated, donated or otherwise
     transferred, whether or not for consideration, by Subscriber except in
     accordance with such laws, rules and regulations and with the Partnership
     Agreement.

          (i)  Subscriber understands and agrees that (i) the effect of the
     foregoing subparagraph (h) is that Subscriber shall be restricted from
     selling or otherwise transferring or disposing of any of the Units except
     in accordance with the Partnership Agreement and pursuant to a registration
     statement rendered effective under the Act and applicable state securities
     laws, or at some indeterminable date in the future, in accordance with the
     Partnership Agreement and an applicable exemption from registration which
     is the subject of a favorable legal opinion rendered by counsel for the
     Partnership, and (ii) as of the date hereof, the Partnership and the
     General Partner have no legal obligation to include the Units in any
     registration statement to be filed under the Act or applicable state
     securities laws.

          (j)  Subscriber understands the fundamental aspects of the business
     and the pool to be conducted by the Partnership and the nature and extent
     of the management and control by the General Partner and the Commodity
     Trading Advisor over the Partnership as a whole, including, but not limited
     to: (i) the trading methods to be used and decisions made in the trading of
     futures, options or other interests by the Partnership; (ii) the transfer
     of Units and the ability or right of a transferee of a Unit to become a
     substituted Limited Partner; (iii) the making of distributions by the
     Partnership; and (iv) the ability or right of a Limited Partner to redeem
     or liquidate its Units.

          (k)  Subscriber understands that the Units are a highly speculative
     investment which involve a high degree of risk, including the possibility
     of the loss of a substantial portion or all of the investment, and that
     neither the Partnership nor the General Partner make any representation or
     warranty as to, and that there is no assurance of, any economic, income,
     tax, profits or other benefits whatsoever from an investment in the Units.
     Subscriber also understands that the Partnership may not ever accomplish
     any of the purposes or objectives of the Partnership.

          (l)  Subscriber understands that the Partnership Agreement establishes
     substantial restrictions on the transferability and liquidation of Units,
     including, but not limited to, the consent of the General Partner.
     Accordingly, Subscriber also understands that Subscriber will need to bear
     the economic risk of the investment in the Units for an indefinite period
     of time and will not be readily able to liquidate the Units in case of an
     emergency.

          (m)  Subscriber understands the tax consequences of an investment in
     the Units and the Partnership and that any federal or state income or other
     tax benefits which may be available to Subscriber may be lost through
     changes to, or in the interpretation of, existing laws

                                       5
<PAGE>
 
     and regulations. Subscriber is relying solely upon the advice of
     Subscriber's personal tax advisors with respect to all tax aspects of an
     investment in the Units and the Partnership.

          (n)  Subscriber has such knowledge and experience in financial and
     business matters that Subscriber is capable of evaluating the merits and
     risks of an investment in the Units. Subscriber is able to bear the
     economic risk of the investment in the Units, and Subscriber has adequate
     financial or other means for providing for Subscriber's current and
     anticipated needs and contingencies and has no need for liquidity in this
     investment.

          (o)  If Subscriber is not a resident of the State of California or an
     entity with its principal place of business in California, Subscriber has
     at least either: (i) a minimum net worth (determined exclusive of home,
     home furnishings and automobiles) of $150,000; or (ii) a minimum annual
     gross income of $45,000 and a minimum net worth (once again determined
     exclusive of home, home furnishings and automobiles) of $45,000. In the
     case of sales to fiduciary accounts, the net worth and income standards may
     be met by the beneficiary, the fiduciary account, or by the donor or
     grantor who directly or indirectly supplies the funds to purchase the
     Units.

          (p)  If Subscriber is a resident of the State of California or is an
     entity with its principal place of business in California, Subscriber has
     at least either (i) a minimum net worth (determined exclusive of home, home
     furnishings and automobiles) of $250,000; or (ii) a minimum annual gross
     income of $65,000 and a minimum net worth (once again determined exclusive
     of home, home furnishings and automobiles) of $100,000. In the case of
     sales to fiduciary accounts, the net worth and income standards may be met
     by the beneficiary, the fiduciary account, or by the donor or grantor who
     directly or indirectly supplies the funds to purchase the Units.

          (q)  Subscriber understands that a notation will be made on the
     records of the Partnership regarding the restrictions on transferability of
     the Units, and that the Partnership Agreement may also contain legends
     addressing the restrictions on transferability of the Units.

          (r)  Subscriber understands that as of the date of the Prospectus the
     Partnership had no financial or operating history.

          (s)  This Subscription Agreement has been duly authorized, executed
     and delivered by Subscriber and constitutes the valid, legal and binding
     obligation of Subscriber, enforceable in accordance with its terms.

     8.   APPOINTMENT OF POWER OF ATTORNEY.
          --------------------------------

          (a)  Subscriber hereby constitutes and appoints the General Partner
     (and any additional or substitute general partners from time to time) the
     true and lawful attorney-in-fact of Subscriber with full power and
     authority for Subscriber, and in the name of Subscriber, to make and
     execute and, if required or if advisable, acknowledge, file and publish
     wherever appropriate:

               (i)     The Partnership Agreement and all authorized or required
          amendments thereto;

               (ii)    The Certificate of Limited Partnership of the Partnership
          and any and all certificates of amendments thereto, and all fictitious
          name certificates, as may be required by or appropriate under the laws
          of Iowa or any other jurisdiction;

               (iii)   Any other instrument which may be required to be filed by
          the Partnership under the laws of any jurisdiction or by any
          governmental agency or authority, or which the General Partner deems
          it advisable to file in order to effectuate any offering of units of
          limited partnership interest by the Partnership, or the terms and
          provisions of this Subscription Agreement, the Prospectus or the
          Partnership Agreement; and

               (iv)    Any documents which may be required to effect or report
          the continuation of the Partnership, the admission of initial,
          additional or substituted Limited Partners or general partners, the
          withdrawal or reduction of capital contributions or the dissolution
          and termination of the Partnership in accordance with this
          Subscription Agreement or the Partnership Agreement.

          (b)  The foregoing grant of authority:

               (i)     Is a special power of attorney coupled with an interest,
          is irrevocable, and shall not be affected by and shall survive the
          death, disability, incompetence, dissolution or other termination of
          Subscriber;

               (ii)    May be exercised by the General Partner either by signing
          separately as attorney-in-fact for Subscriber or by a single signature
          of the General Partner acting as attorney-in-fact for all of the
          parties executing any instrument; and

               (iii)   Shall survive the delivery of an assignment of a Unit by
          Subscriber.

          (c)  Subscriber acknowledges and agrees that the Partnership Agreement
     also contains a grant of authority and power of attorney by each and all of
     the Limited Partners to the General Partner, and that Subscriber, by
     adoption of the Partnership Agreement hereby, also grants such authority
     and power of attorney to the General Partner. The grants of authority and
     powers of attorney set forth herein and in the Partnership Agreement are
     each respectively in addition and cumulative to the other, and neither
     restricts or limits the other.

         -----------------------------
sale and issuance of the Units to Subscriber were and will be based upon the
representations, warranties, acknowledgments and agreements of Subscriber

Partnership, the General Partner, the Underwriter and any person or entity
acting for or on the Partnership's, the General Partner's or the Underwriter's
behalf with respect to the offer, sale and/or issuance of the Units, and to hold

of this Subscription Agreement shall not be affected thereby and shall continue
to be valid and enforceable. In the event any provision of this Subscription

legal and enforceable if modified, then such provision shall be deemed to be
amended to such extent as shall be necessary for such provision to be valid,
legal and enforceable and it shall be enforced to that extent. This Subscription
Agreement and the representations, warranties, acknowledgments and agreements

1.   NATURE OF BUSINESS

     Portfolio Boost III, L.P. (the "Partnership") is an Iowa limited
     partnership organized on June 17, 1998 with its principal office in
     Warrenville, Illinois.  The Partnership has not yet commenced operations.
     The only transaction to date is the original capital contribution of $1,000
     by the initial limited partner, who is an officer of the General Partner.
     The General Partner may, but is not obligated to make a capital
     contribution.  The Partnership will terminate on December 31, 2050, or upon
     the occurrence of an event causing an earlier termination as set forth in
     the Limited Partnership Agreement.

     The Partnership is a single advisor commodity pool which will be engaged in
     the business of speculative trading of various domestic and foreign futures
     contracts, options and other interests pursuant to one of the trading
     programs of the Partnership's commodity trading advisor (CTA).  The
     Partnership's principal objective is to generate increased capital for the
     partners, but there can be no assurance that the Partnership will achieve
     this objective since it is involved in a speculative, volatile, high risk
     business.  The Limited Partnership Agreement provides the Partnership may
     commence trading after the General Partner has accepted subscriptions for
     500 units of limited partnership interest ("Units") at $1,000 per Unit.  If
     subscriptions for a minimum of 500 Units have not been accepted within nine
     months of the date of the Prospectus, the offering will terminate and all
     amounts paid by the subscribers will be returned.
  
     Interests in the Partnership are evidenced by Units.  Profits and losses of
     the Partnership are allocated to the partners pro rata based upon the
     respective number of Units held.  The Partnership's income tax attributes
     pass-through to the partners of the Partnership.

2.   FEES AND EXPENSES
 
     Fees
     ----

     The Partnership will pay to its commodity pool operator and General
     Partner, Portfolio Boost, L.L.C., a monthly management fee in an amount
     equal to one-half of one percent  (0.5%) of

<PAGE>
 
Portfolio Boost III, L.P.
NOTES TO BALANCE SHEET
SEPTEMBER 30, 1998
- --------------------------------------------------------------------------------

     the Partnership's net assets as of the close of business on the last
     business day of each month.  The Partnership will also pay to its General
     Partner a quarterly incentive fee in an amount equal to 15% of New Trading
     Profits, as defined in the Limited Partnership Agreement, for each quarter.
   
     The General Partner is solely responsible for the payment of compensation
     to the Partnership's CTA, to the Partnership's agent (Agent) and to the
     Underwriter of the offering of Partnership Units.  Additionally, the
     General Partner will provide, at its cost, vacation awards to qualifying
     Limited Partners.

     All trading decisions will be made for the Partnership by its CTA, Quiet
     Systems Limited.  The sole officer of the General Partner and certain
     members of his family are some of the beneficiaries of the trust which owns
     the CTA.

     The Partnership's Agent for purposes of receiving the signals generated by
     the CTA's trading program and communicating the trades which are directed
     to be made is Frischmeyer Trading Corporation.  The individual who controls
     the Agent and certain members of his family are some of the beneficiaries
     of the trust which owns the CTA.

     The Underwriter of the offering is Vacation Investors, Inc., which is owned
     by the sole officer of the General Partner.

     Other Expenses
     --------------

     The Partnership is responsible for payment of brokerage commissions and
     other fees incidental to trading to its futures commission merchant, First
     Options of Chicago, Inc., payment of exchange and National Futures
     Association fees, and payment of all other expenses of the Partnership,
     including organization and offering (excluding underwriting) expenses,
     legal and accounting fees and meeting and office expenses.

3.   DISTRIBUTIONS AND REDEMPTIONS

     Distributions, if any, will be made only at such times and in such amounts
     as determined by the General Partner, in its sole


<PAGE>
 
Portfolio Boost III, L.P.
NOTES TO BALANCE SHEET

     discretion.  With the consent of the General Partner, a Limited Partner may
     liquidate, with at least sixty days prior written notice, the Units held by
     the Limited Partner at Net Asset Value Per Unit on the liquidation date.
   
     For purposes of calculating Net Asset Value Per Unit, Net Assets includes
     partners' capital, as determined for financial statement purposes, plus an
     adjustment for unamortized organizational and offering costs.
     Organizational and offering costs are expensed when incurred for financial
     statement purposes.  For purposes of calculating Net Asset Value Per Unit,
     these costs are capitalized and amortized over a period of five years.

1.   ORGANIZATION

     Nature of Business
     ------------------

     Portfolio Boost, L.L.C. (Company) was organized on May 20, 1998 with Corn
     Belt Management, Inc. being merged into the Company on May 22, 1998. The
     Company serves as the general partner and commodity pool operator for
     commodity pools.

     The Company is the general partner and commodity pool operator of Corn Belt
     Commodities Round Trip Limited Partnership (CBCRT), which is a limited
     partnership operating a commodity pool.  Corn Belt Management, Inc. was the
     prior general partner and commodity pool operator of CBCRT.

     The Company will also serve as general partner and commodity pool operator
     of four commodity pools currently being organized which have not yet begun
     operations, Portfolio Boost I, L.P.; Portfolio Boost II, L.P.; Portfolio
     Boost III, L.P.; and Portfolio Boost MJF, L.P.  These commodity pools are
     expected to begin operations in 1998 or early 1999.

     Under the terms of the limited partnership agreements, the Company earns
     monthly management fees and quarterly incentive fees and is liable for
     certain expenses of the partnerships, such as commodity trading advisor
     fees and underwriting fees.

     As the general partner, the Company is liable for the obligations of the
     limited partnerships.  Management is unaware of any such liabilities which
     would have a material adverse affect on the Company's financial position.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Cash and Cash Equivalents
     -------------------------

     The Company considers all demand deposit accounts, money market funds and
     debt securities with an original maturity of three months or less to be
     cash and cash equivalents.

PORTFOLIO BOOST, L.L.C.
NOTES TO BALANCE SHEET
SEPTEMBER 30, 1998
- --------------------------------------------------------------------------------

     Marketable Securities
     ---------------------

     The Company considers all investments in marketable equity and debt
     securities as trading securities and are carried at fair value.
    
     Airline Ticket Credits and Deferred Revenue     
     -------------------------------------------
    
     The Company has airline ticket credits from an unrelated travel management
     company which are used to purchase airline tickets. The cost of tickets
     purchased with the credits generally approximates the lowest fare amount
     available in the market place on the date the tickets are purchased.     

     The airline ticket credits are used in the Company's operations as a
     general partner and commodity pool operator for various limited
     partnerships. In connection with these activities, the Company provides
     vacation awards to those limited partners who meet specified
     qualifications.
    
     The airline ticket credits were received by the Company in exchange for
     consulting services provided to the unrelated travel management company.
     The credits were earned based on an amount negotiated with the unrelated
     travel management company for the consulting services provided. The Company
     does not anticipate any such future exchanges.     
    
     The revenue from consulting services provided is deferred and is recognized
     when the airline ticket credits are used.    

     Costs Reimbursable From Limited Partnerships
     --------------------------------------------

     The Company is the general partner of four limited partnerships that are
     currently being organized which will operate commodity pools. These limited
     partnerships are currently preparing offering documents and in the process
     of filing them with various regulatory agencies which is required before
     the limited partnerships can accept capital contributions.

     The Company, as the general partner, has paid costs related to the
     preparation of the offering documents and the regulatory filings. These
     costs are reimbursable from the limited partnerships once the limited
     partnerships have received the minimum amount of capital contributions and
     commenced operations.
     
     The Company continually monitors and assesses the progress of each
     offering. If an offering is aborted or discontinued, the 
<PAGE>
 
     costs related to that limited partnership would be immediately charged to
     expense.

     Residential Rental Property
     ---------------------------

     This property is held for sale, and is carried at the lower of cost or fair
     value less estimated costs to sell.

     Investment in Limited Partnership
     ---------------------------------

     The investment in CBCRT, a limited partnership in which the Company is the
     general partner but not the majority owner, is accounted for under the
     equity method.

     Income Taxes
     ------------

     The Company is a limited liability company under which the income tax
     attributes pass-through to the members of the Company. Therefore, no income
     tax expense is recorded by the Company.

     Use of Estimates
     ----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the amounts reported in the financial statements
     and accompanying notes. Actual results could differ from those estimates.

3.   REGULATORY REQUIREMENTS

     The Company is subject to various regulatory guidelines relating to the
     maintenance of a minimum amount of regulatory net worth. Under the
     guidelines regulatory net worth is generally required equal to five percent
     of the sum of partner contributions received and limited partnership
     interests being offered in limited partnerships for which the Company is
     the general partner. However, pursuant to the regulatory net worth
     requirements, net worth may not be less than $50,000, but is not required
     to exceed $1,000,000.

     institutions for the benefit of the Company.

4.   MEMBERS' EQUITY

     Members' Equity at September 30, 1998 consists of:

                                 Voting    Nonvoting

     ---------------------------

     Member to the extent of its capital account balance and then to the
     Nonvoting Members.

     Earnings of the Company attributable to CBCRT are allocated to the Voting
     Member. The remaining net profits (Net Profits) of the Company are
     generally allocated (i) first to Nonvoting Members to the extent of
     previously allocated losses; (ii) second to the Voting Member to the extent
     of previously allocated losses; (iii) third to Nonvoting Members equal to
     an aggregate of 28% of Net Profits of the Company; and (iv) the balance of

     Nonvoting Members within thirty days after December 31, 2001, an amount
     equal to the capital account of each member less any unpaid subscription

     has agreed to make capital contributions if the Company is unable to
     otherwise make such payments.

               PART II - INFORMATION NOT REQUIRED IN PROSPECTUS


Item 24.  Indemnification of Officers and Directors

    The Partnership's limited partnership agreement provides that the
Partnership shall defend, indemnify, and hold the General Partner harmless from
and against any loss, liability, damage, cost or expense incurred by the General
Partner and arising from any act, omission, activity or conduct undertaken by or
on behalf of the Partnership and reasonably believed by the General Partner to
be within the scope of authority conferred on it by the limited partnership
agreement. Such indemnity is available only if the General Partner (a) acted in
good faith and in a manner the General Partner reasonably believed to be in, or
not opposed to, the best interests of the Partnership, and (b) the act,
omission, activity or conduct in question did not constitute negligence or
misconduct. No indemnification may be made with respect to alleged violations of
federal or state securities laws unless (i) there has been a successful
adjudication on the merits of each count involving alleged securities law
violations, or (ii) such claim has been dismissed by a court with prejudice on
the merits; or (iii) a court approves a settlement of the claims against the
indemnitee and finds that the indemnification of the settlement and related
costs and expenses should be made. In the case of (iii), the indemnified party
must apprise the court of the position of the Securities and Exchange Commission
and of the securities administrator of the state in which the plaintiffs in the
underlying case claim they were offered or sold Units with respect to
indemnification for securities laws violations before seeking any approval from
the court for indemnification.

    The Articles of Organization of Portfolio Boost, L.L.C., the General Partner
of the Partnership, provide that a voting member of the General Partner shall
not be personally liable to the General Partner or its members for damages for
breach of a fiduciary duty as a voting member, except for liability (i) for
breach of the voting member's duty of loyalty to the General Partner or its
members, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, or (iii) for a transaction
from which the voting member derives an improper personal benefit or wrongful
distribution in violation of Section 490A.807 of the Iowa Limited Liability
Company Act. The Articles of Organization of the General Partner further provide
that if the foregoing Act or any other applicable law is amended to authorize
the further elimination or limitation of the liability of members, then the
liability of the members of the General Partner will be eliminated or limited to
the extent of any such amendment without any further action on behalf of the
General Partner or its members.

    The Operating Agreement of the General Partner provides indemnification for
each person who is or was a member of the General Partner to the maximum extent
that a corporation has authority to indemnify a director of the corporation by
or under the Iowa Business Corporation Act or other applicable law, as the same
now exists or may hereafter be amended or changed, but in the case of any such
amendment or change, only to the extent that the amendment or change would
permit broader indemnification than is then currently the case. Any person's
right to indemnification is conditioned upon the General Partner being afforded
an opportunity to participate directly on behalf of such person in any such
claim, action, suit or proceeding or any settlement discussions relating
thereto, and with respect to any settlement or other non-adjudicated disposition
of any of the foregoing, entitlement to indemnification is also conditioned upon
the prior approval of the General Partner of the proposed settlement or other
non-adjudicated disposition. The General Partner's Operating Agreement also
would permit the General Partner to purchase and maintain insurance to provide
such an indemnification.

     (c)  Not Applicable
     (d)  Not Applicable
     (e)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
