                       ___________________________________

                        WARRANTS TO PURCHASE COMMON STOCK

                                       OF

                                RAPID CAST, INC.           
                       ___________________________________

          This is to Certify That, For Value Received, [NAME], or assigns 
("Holder"), is entitled to purchase, subject to the provisions of this 
Agreement, from Rapid Cast, Inc., a Delaware corporation ("RCI"), _____ 
THOUSAND (______) fully paid, validly issued and nonassessable shares of 
Common Stock, $.001 par value, of RCI ("Common Stock") at any time or from 
time to time during the 7-year period (the "Exercise Period") commencing on 
the date hereof at an initial exercise price equal to $2.25 per share of 
Common Stock. The number of shares of Common Stock to be received upon the 
exercise of this Warrant and the price to be paid for each share of Common 
Stock may be adjusted from time to time as hereinafter set forth.  The shares 
of Common Stock deliverable upon such exercise, and as adjusted from time to 
time, are hereinafter sometimes referred to as "Warrant Shares" and the 
exercise price of a share of Common Stock in effect at any time and as 
adjusted from time to time is hereinafter sometimes referred to as the 
"Exercise Price."   

          (a)  EXERCISE OF WARRANT.  This Warrant may be exercised in whole or
in part at any time or from time to time during the Exercise Period.

          (b)  RESERVATION OF SHARES.  RCI shall at all times reserve for
issuance and/or delivery upon exercise of the Warrant such number of shares of
the Common Stock as shall be required for issuance and delivery upon exercise of
this Warrant.





          (c)  FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant.  

          (d)  ELIMINATION OF FRACTIONAL SHARES.  All fractional shares shall be
eliminated by rounding any fraction down to the nearest whole number of shares
of Common Stock.

          (e)  RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in RCI, either at law or equity, and the
rights of the Holder are limited to those expressed herein and are not
enforceable against RCI except to the extent set forth herein.

          (f)  ANTI-DILUTION PROVISIONS.  The Exercise Price in effect at any
time and the number and kind of securities purchasable upon the exercise of the
Warrant shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (1)  In case RCI shall (i) declare a dividend or make a distribution on its
     outstanding shares of Common Stock in shares of Common Stock, (ii)
     subdivide or reclassify its outstanding shares of Common Stock into a
     greater number of shares, or (iii) combine or reclassify its outstanding
     shares of Common Stock into a smaller number of shares, the Exercise Price
     in effect at the time of the record date for such dividend or distribution
     or of the effective date of such subdivision, combination or
     reclassification shall be adjusted so that it shall equal the price
     determined by multiplying the Exercise Price by a fraction, the denominator
     of which shall be the number of shares of Common Stock outstanding after
     giving effect to such action, and the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to such
     action.  Such adjustment shall be made successively whenever any event
     listed above shall occur.

     (2)  In case RCI shall fix a record date for the issuance of rights or
     warrants (other than employee stock options exercisable at fair market
     value on the date of grant) to all holders of its Common Stock entitling
     them to subscribe for or purchase shares of Common Stock (or securities
     convertible into Common Stock) at a price (the "Subscription Price") (or
     having a conversion price per share) less than the current market price of
     the Common Stock (as defined in clause (5) below) on the record date
     mentioned below, the Exercise Price shall be adjusted so that the same
     shall equal the price determined by multiplying the Exercise Price in
     effect immediately prior to the date of issuance by a fraction, the
     numerator of which shall be the sum of the number of shares of Common Stock
     outstanding on the record date mentioned below and the number of additional
     shares of Common Stock which the aggregate offering price of the total
     number of shares of Common Stock so offered (or the aggregate conversion
     price of the convertible securities so offered) would purchase at such
     current market price per share of the Common Stock, and the denominator of
     which shall be the sum of the number of shares of Common Stock outstanding
     on such record date and the number of additional shares of Common Stock
     offered for subscription or purchase (or into which the convertible
     securities so offered are convertible).  Such adjustment shall be made
     successively whenever such rights or warrants are issued and shall become
     effective




     immediately after the record date for the determination of stockholders 
     entitled to receive such rights or warrants; and to the extent that 
     shares of Common Stock are not delivered (or securities convertible into 
     Common Stock are not delivered) after the expiration of such rights or
     warrants the Exercise Price shall be readjusted to the Exercise Price which
     would then be in effect had the adjustments made upon the issuance of such
     rights or warrants been made upon the basis of delivery of only the number
     of shares of Common Stock (or securities convertible into Common Stock)
     actually delivered.

     (3)  In case RCI shall hereafter distribute to all holders of its Common
     Stock evidences of its indebtedness or assets (excluding cash dividends or
     distributions and dividends or distributions referred to in Subsection (1)
     above) or subscription rights or warrants (excluding those referred to in
     Subsection (2) above), then in each such case the Exercise Price in effect
     thereafter shall be determined by multiplying the Exercise Price in effect
     immediately prior thereto by a fraction, the numerator of which shall be
     the total number of shares of Common Stock outstanding multiplied by the
     current market price per share of Common Stock (as defined below), less the
     fair market value (as determined by RCI's Board of Directors) of said
     assets or evidences of indebtedness so distributed or of such rights or
     warrants, and the denominator of which shall be the total number of shares
     of Common Stock outstanding multiplied by such current market price per
     share of Common Stock.  Such adjustment shall be made successively whenever
     such a record date is fixed.  Such adjustment shall be made whenever any
     such distribution is made and shall become effective immediately after the
     record date for the determination of stockholders entitled to receive such
     distribution.

     (4)  Whenever the Exercise Price payable upon exercise of each Warrant is
     adjusted pursuant to Subsections (1), (2) and (3) above, the number of
     Warrant Shares purchasable upon exercise of these Warrant shall
     simultaneously be adjusted by multiplying the number of Shares initially
     issuable upon the exercise of these Warrant by the Exercise Price in effect
     on the date hereof and dividing the product so obtained by the Exercise
     Price, as adjusted.
               
     (5)  For the purpose of any computation under Subsections (2) and (3)
     above, the current market price per share of Common Stock at any date shall
     be deemed to be the average of the daily closing prices for 30 consecutive
     business days before such date.  The closing price for each day shall be
     the last sale price or, in case no such reported sale takes place on such
     day, the average of the last reported bid and asked prices, in either case
     on the principal national securities exchange on which the Common Stock is
     admitted to trading or listed, or if not listed or admitted to trading on
     such exchange, the average of the highest reported bid and lowest reported
     asked prices as reported by NASDAQ, or other similar organization if NASDAQ
     is no longer reporting such information, or if not so available, the fair
     market price as determined in good faith by the Board of Directors.

     (6)  No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($.05) in such price; provided, however, that any adjustment which by
     reason of this Subsection is not




     required to be made shall be carried forward and taken into account in 
     any subsequent adjustment required to be made hereunder.  All 
     calculations under this Section (f) shall be made to the nearest cent 
     or to the nearest one-hundredth of a share, as the case may be.  

     (7)  In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (1) above, the Holder of this Warrant thereafter
     shall become entitled to receive any shares of RCI, other than Common
     Stock, thereafter the number of such other shares so receivable upon
     exercise of this Warrant shall be subject to adjustment from time to time
     in a manner and on terms as nearly equivalent as practicable to the
     provisions with respect to the Common Stock contained in Subsections (1) to
     (6), inclusive above.

     (8)  Irrespective of any adjustments in the Exercise Price or the number or
     kind of shares purchasable upon exercise of this Warrant, Warrants
     theretofore or thereafter issued may continue to express the same price and
     number and kind of shares as are stated in the similar Warrant initially
     issuable pursuant to this Agreement.

          (g)  OFFICER'S CERTIFICATE.  Whenever the Exercise Price shall be
adjusted as required by the provisions of the foregoing Section, RCI shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment.  Each such officer's certificate shall be
made available at all reasonable times for inspection by the holder or any
holder of a Warrant executed and delivered pursuant to Section (a).

          (h)  NOTICES TO WARRANT HOLDERS.  So long as this Warrant shall be
outstanding, (i) if RCI shall pay any dividend or make any distribution upon the
Common Stock, or (ii) if RCI shall offer to the holders of Common Stock for
subscription or purchase by them any share of any class or any other rights, or
(iii) if any capital reorganization of RCI, reclassification of the capital
stock of RCI, consolidation or merger of RCI with or into another corporation,
sale, lease or transfer of all or substantially all of the property and assets
of RCI to another corporation, or voluntary or involuntary dissolution,
liquidation or winding up of RCI shall be effected, then in any such case, RCI
shall cause to be mailed by certified mail to the Holder, at least fifteen days
prior to the date specified in (x) or (y) below, as the case may be, a notice
containing a brief description of the proposed action and stating the date on
which (x) a record is to be taken for the purpose of such dividend, distribution
or rights, or (y) such reclassification, reorganization, consolidation, merger,
conveyance, lease, dissolution, liquidation or winding up is to take place and
the date, if any is to be fixed, as of which the holders of Common Stock or
other securities shall receive cash or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation or winding up.

          (i)  RECLASSIFICATION, REORGANIZATION OR MERGER.  In case of 




any reclassification, capital reorganization or other change of outstanding 
shares of Common Stock of RCI, or in case of any consolidation or merger of 
RCI with or into another corporation (other than a merger with a subsidiary 
in which merger RCI is the continuing corporation and which does not result 
in any reclassification, capital reorganization or other change of 
outstanding shares of Common Stock of the class issuable upon exercise of 
this Warrant) or in case of any sale, lease or conveyance to another 
corporation of the property of RCI as an entirety, RCI shall cause effective 
provisions to be made so that the Holder shall have the right by exercising 
this Warrant prior to the expiration of the Warrants, to purchase the kind 
and amount of shares of stock and other securities and property receivable 
upon such reclassification, capital reorganization and other change, 
consolidation, merger, sale or conveyance by a holder of the number of shares 
of Common Stock which might have been purchased upon exercise of this Warrant 
immediately prior to such reclassification, change, consolidation, merger, 
sale or conveyance.  Any such provision shall include provision for 
adjustments which shall be as nearly equivalent as may be practicable to the 
adjustments provided for in this Warrant.  The foregoing provisions of this 
Section (i) shall similarly apply to successive reclassifications, capital 
reorganizations and changes of shares of Common Stock and to successive 
consolidations, mergers, sales or conveyances.  In the event that in 
connection with any such capital reorganization or reclassification, 
consolidation, merger, sale or conveyance, additional shares of Common Stock 
shall be issued in exchange, conversion, substitution or payment, in whole or 
in part, for a security of RCI other than Common Stock, any such issue shall 
be treated as an issue of Common Stock covered by the provisions of 
Subsection (1) of Section (f) hereof.
     
          (j)  REGISTRATION RIGHTS.  Holder has been granted certain
registration rights as set forth in the Registration Rights Agreement, dated as
of the date hereof, by and between RCI and Holder and the holders of certain
warrants similar to this Warrant.
