received directly by Lender, all such payment shall be made in immediately

required to surrender such payment or Proceeds to any Person, because such
payment or Proceeds is invalidated, declared fraudulent, set aside, determined
to be void or voidable as a preference, or a diversion of trust funds, or for
any other reason, then the Obligations or part thereof intended to be satisfied
shall be revived and continue and this Agreement shall continue in full force as
if such payment or Proceeds had not been received by Lender, and Borrower shall
be liable to pay to Lender and hereby does indemnify Lender and holds Lender
harmless for the amount of such payment or Proceeds surrendered. The provisions
of this Section 4.5 shall be effective notwithstanding any contrary action which
may have been taken by Lender in reliance upon such payment or Proceeds, and any
such contrary action so taken shall be without prejudice to Lender's rights
under this Agreement and shall be deemed to have been conditioned upon such
payment or Proceeds having become final and irrevocable. The provisions of this
Section 4.5 shall survive the termination of this Agreement.

5. LENDER'S BOOKS AND RECORDS; QUARTERLY STATEMENTS.

            Borrower and ICC agree that the books and records of Lender showing

therefrom, and shall constitute prima facie proof thereof, irrespective of
whether any Obligation is also evidenced by a promissory note or other
instrument. Lender will provide to Borrower a quarterly statement of Loans,
payments, and other transactions pursuant to this Agreement. Such statement
shall be deemed correct, accurate, and binding on Borrower and as an account

notifies Lender in writing to the contrary within thirty (30) days after such
statement is rendered. In the event a timely written notice of objections is
given by Borrower, only the items to which exception is expressly made will be
considered to be disputed by Borrower.

thereof, now or hereafter held or received by, or in transit to, Lender from or
for Borrower or ICC, whether for safekeeping, pledge, custody, transmission,
collection or otherwise, including all of Borrower's and ICC's deposit accounts,
credits, and balances with any financial institution or local exchange carrier,
and all claims of Borrower or ICC against any financial institution or local
exchange carrier at any time existing relating to Borrower's and ICC's deposit
accounts with any financial institution with which Borrower or ICC maintains
deposits or Borrower's or ICC's accounts with any local exchange carrier with
which Borrower or ICC has a contractual relationship or otherwise does business;
(iv) all of Borrower's and ICC's deposit accounts with any financial
institutions with which Borrower or ICC maintains deposits; and (v) all books,

other Property in which Lender may at any time be granted a Lien, being herein
collectively referred to as the "Collateral"). Lender shall have all of the
rights of a secured party with respect to the Collateral under the UCC and other
applicable laws.

            6.1.2. All Obligations shall constitute a single loan secured by the
Collateral. Lender may, except as otherwise provided in the Loan Documents, in
its sole discretion, (i) exchange, waive, or release any of the Collateral, (ii)
apply Collateral and direct the order or manner of sale thereof as Lender may
determine and (iii) settle, compromise, collect, or otherwise liquidate any
Collateral in any manner, all without affecting the Obligations or Lender's
right to take any other action with respect to any other Collateral.

      6.2. Perfection and Protection of Security Interest.

            6.2.1. Borrower and ICC shall each, at their expense, perform all
steps requested by Lender at any time to perfect, maintain, protect and enforce
the Security Interest, including: (i) executing and filing financing or
continuation statements, and


                                       12


amendments thereof, in form and substance satisfactory to Lender; (ii)
delivering to Lender the originals of all instruments, documents, and chattel
paper, and all other Collateral of which Lender determines it should have

therein, duly endorsed or assigned to Lender without restriction; (iii) placing
notations on Borrower's or ICC's books of account, as the case may be, to

financing statement is sufficient as a financing statement. If any Collateral is
at any time in the possession or control of any warehouseman, bailee or any of
Borrower's or ICC's agents or processors, then Borrower or ICC shall notify
Lender thereof and shall notify such Person of the Security Interest in such
Collateral and, upon Lender's request, instruct such Person to hold all such
Collateral for Lender's account subject to Lender's instructions. If at any time
any Collateral is located on any Premises that are not owned by Borrower or ICC,
then Borrower or ICC shall obtain written waivers, in form and substance
satisfactory to Lender, of all present and future Liens to which the owner or
lessor or any mortgagee of such Premises may be entitled to assert against the
Collateral. From time to time, Borrower or ICC shall, upon Lender's request,
execute and deliver confirmatory written instruments pledging the Collateral to
Lender but Borrower's failure to do so shall not affect or limit the Security
Interest. So long as this Agreement is in effect, and until all Obligations have
been fully satisfied, the Security Interest shall continue in full force and
effect in all Collateral. Prior hereto or concurrently herewith Borrower shall
deliver to Lender (i) certificates representing the Rapid Cast, Inc. equity
securities, the sales proceeds of which are pledged as security for the
Obligations pursuant to Section 6.1 and (ii) certificates representing the ICC
equity securities endorsed in blank and pledged hereunder as security of the
Obligations pursuant to Section 6.1. Lender shall hold the certificates
representing the Rapid Cast, Inc. equity securities as security for Borrower's
covenant not to sell the securities represented by such certificates without the
prior consent of Lender.

correctly identifies any of such facilities and locations that are not owned by
Borrower and sets forth the names of the owners and lessors of, and, to the best
of Borrower's knowledge, the holders of any mortgages on such facilities and

location other than those listed on Schedule 6.3, and that it will not otherwise
change or add to any of such locations, unless it gives Lender at least thirty


                                       13

Collateral with all reasonable care and will use the Collateral for lawful
purposes only; (iv) Borrower and ICC will not, without Lender's prior written
approval, sell, or dispose of, or permit the sale or disposition of any
Collateral except in the ordinary course of business; and (v) Borrower will not,
without Lender's prior written approval, sell, dispose of, transfer or assign
any equity securities of Rapid Cast, Inc., now or hereafter owned by Borrower
(beneficially or otherwise). The inclusion of Proceeds in the Collateral shall
not be deemed Lender's consent to any sale or other disposition of the
Collateral except as expressly permitted herein.

      6.5. Access and Examination.

            Lender shall at all reasonable times have access to, examine, audit,
make extracts from and inspect Borrower's and ICC's records, files and books of
account and the Collateral and may discuss Borrower's and ICC's affairs with
Borrower's and ICC's officers and management. Borrower and ICC shall deliver to
Lender any instrument necessary for Lender to obtain records from any service
bureau maintaining records for Borrower. Lender may, at any time, and at
Borrower's expense, make copies of all of Borrower's and ICC's books and
records, or require Borrower or ICC to deliver such copies to Lender. Lender
may, without expense to Lender, use such of Borrower's and ICC's personnel,
supplies and premises as may be reasonably necessary for maintaining or
enforcing the Security Interest.

      6.6. Insurance.

            6.6.1. Borrower or ICC shall insure the Collateral against loss or
damage by fire with extended coverage, theft, burglary, pilferage, loss in

Real Property is located as "flood prone" or a "flood risk area," as defined by
the Flood Disaster Protection Act of 1973, in an amount to be reasonably
determined by Lender, and shall comply with the additional requirements of the
National Flood Insurance Program as set forth therein. Borrower or ICC shall
cause Lender to be named in each such policy as secured party or mortgagee and
loss payee or additional insured, in a manner acceptable to Lender. Each policy
of insurance shall contain a clause or endorsement requiring the insurer to give
not less than thirty (30) days' prior written notice to Lender in the event of
cancellation of the policy for any reason whatsoever and a clause or endorsement
stating that the interest of Lender shall not be impaired or invalidated by any
act or neglect of Borrower or ICC or the owner of any Premises where Collateral
is located nor by the use of such Premises for purposes


                                       14


more hazardous than are permitted by such policy. All premiums for such
insurance shall be paid by Borrower or ICC when due, and certificates of
insurance and, if requested, photocopies of the policies shall be delivered to
Lender. If Borrower or ICC fails to procure such insurance or to pay the
premiums therefor when due, Lender may (but shall not be required to) do so and
charge the costs thereof to Borrower's loan account. Borrower or ICC shall
promptly notify Lender of any loss, damage, or destruction to the Collateral or
arising from its use, whether or not covered by insurance.

            6.6.2. Lender is hereby authorized to collect all insurance proceeds
directly. After deducting from such proceeds the expenses, if any, incurred by
Lender in the collection or handling thereof, Lender may apply such proceeds to
the reduction of the Obligations, in such order as Lender determines, or, at
Lender's option, may permit or require Borrower to use such money, or any part
thereof, to replace, repair, restore or rebuild the Collateral in a diligent and
expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction.

      6.7. Collection of Accounts; Payments.

            6.7.1. Prior to Closing, Borrower and ICC shall establish a lockbox
service for collections of Accounts at a bank determined by Lender and pursuant
to documentation satisfactory to Lender. Borrower and ICC shall instruct all
Account Debtors to make all payments directly to the address established for
such service. If, notwithstanding such instructions, Borrower or ICC receives
any Proceeds of Accounts, it shall receive such payments as Lender's trustee and
shall immediately deliver such payments to Lender in their original form duly
endorsed in blank or deposit them into a Payment Account, as Lender may direct.
All collections received in any such lockbox or Payment Account or directly by
Borrower, ICC or Lender, and all funds in any Payment Account or other account
to which such collections are deposited, shall be the sole property of Lender
and shall be subject to Lender' s sole control. Until Borrower or ICC defaults
under this Agreement or until Lender reasonably believes a Borrower or ICC
default is imminent hereunder, Lender will disburse such funds in the lock box
account to Borrower to be used by Borrower in the ordinary course of business
subject to the terms of this Agreement. Lender may, at any time, notify obligors
that the Accounts have been assigned to Lender and of the Security Interest
therein, and may collect them directly and charge the collection costs and
expenses to Borrower's loan account. Borrower and ICC, at Lender's request,
shall execute and deliver to Lender such documents as Lender shall require to
grant Lender access to any post office box in which collections of Accounts are
received.

            6.7.2. If sales of Inventory are made for cash or cash equivalents,
Borrower and ICC shall immediately deliver to Lender the identical checks, cash
or other forms of payment which Borrower or ICC receives.


                                       15


            6.7.3. All payments received by Lender on account of Accounts or as
Proceeds of other Collateral will be Lender's sole property and will be credited
to Borrower's loan account (conditional upon final collection) upon the date of
Lender's receipt thereof.

            6.7.4. In the event Borrower repays all of the Obligations upon the
termination of this Agreement, other than through Lender's receipt of payments
on account of Accounts or Proceeds of other Collateral, such payment will be
credited (conditional upon final collection) upon the date of Lender's receipt
thereof.

      6.8. Equipment.

            Borrower and ICC represent and warrant to Lender that all of the
Equipment is and will be used or held for use in Borrower's or ICC's business.

condition and repair (ordinary wear and tear excepted) and shall make all
necessary replacements thereof. Borrower or ICC shall promptly inform Lender of
any material additions to or deletions from the Equipment. Borrower and ICC
shall not permit any Equipment to become a fixture to real property or an
accession to other personal property, unless Lender has a valid, perfected, and
first priority Security Interest in such real or personal property. Borrower and
ICC shall not, without Lender's prior written consent, sell, lease as a lessor,
or otherwise dispose of any of the Equipment; provided, however, that Borrower
and ICC may dispose of obsolete or unusable Equipment having an orderly
liquidation value no greater than $5,000 individually, and $50,000 in the
aggregate in any Fiscal Year, without Lender's consent, subject to the
conditions set forth below. In the event any of the Equipment is sold,
transferred or otherwise disposed of with Lender's prior written consent or as
otherwise permitted hereby and: (i) such sale, transfer or disposition is
effected without replacement of such Equipment, or such Equipment is replaced by
Equipment leased by Borrower or ICC, or by Equipment purchased by Borrower or
ICC subject to a lien or other right constituting a Permitted Lien, then
Borrower or ICC shall deliver all of the cash proceeds of any such sale,
transfer or disposition to Lender, which proceeds shall be applied to the
repayment of the Obligations; or (ii) such sale, transfer or disposition is made
in connection with the purchase by Borrower or ICC of replacement Equipment
(other than subject to a Permitted Lien), then Borrower or ICC shall use the
proceeds of such sale, transfer or disposition to finance the purchase by
Borrower or ICC of replacement Equipment and shall deliver to Lender written
evidence of the use of the proceeds for such purchase. All replacement Equipment
purchased by Borrower or ICC shall be free and clear of all liens, claims and

      11.2. Remedies.

            11.2.1. If an Event of Default exists, Lender may, without notice to
or demand on Borrower, do one or more of the following at any time or times and
in any order: (i) terminate this Agreement; (ii) declare any or all Obligations
to be immediately due and payable (provided, however, that upon the occurrence
of any Event of Default described in Section , Section , Section or Section ,
all Obligations shall automatically become immediately due and payable without
any action by Lender); and (iii) pursue its other rights and remedies under the
Loan Documents and applicable law.

            11.2.2. If an Event of Default exists: (i) Lender shall have, in
addition to all other rights, the rights and remedies of a secured party under
the UCC; (ii) Lender may, at any time, take possession of the Collateral and
make it available to Lender at a place or places reasonably convenient to
Lender; (iii) Lender may use any and all of the Collateral including the General
Intangibles to continue the business of Borrower or ICC and (iv) Lender may sell
and deliver any Collateral at public or private sales, for cash, upon credit or
otherwise, at such prices and upon such terms as Lender deems advisable, in its
sole discretion, and may, if Lender deems it reasonable, postpone or adjourn any
sale of the Collateral by an announcement at the time and place of sale or such
postponed or adjourned sale without giving a new notice of sale. Without in any
way requiring 


                                       31


notice to be given in the following manner, Borrower and ICC agree that any
notice by Lender of sale, disposition or other intended action hereunder or in
connection herewith, whether required by the UCC or otherwise, shall constitute
reasonable notice to Borrower and ICC if such notice is mailed by registered or
certified mail, return receipt requested, postage prepaid, or is delivered
personally against receipt, at least five (5) days prior to such action to
Borrower's address specified in or pursuant to Section . If any Collateral is
sold on terms other than payment in full at the time of sale, no credit shall be
given against the Obligations until Lender receives payment, and if the buyer
defaults in payment, Lender may resell the Collateral without further notice to
Borrower or ICC. In the event Lender seeks to take possession of all or any
portion of the Collateral by judicial process, Borrower and ICC irrevocably
waives: (a) the posting of any bond, surety or security with respect thereto
which might otherwise be required; (b) any demand for possession prior to the
commencement of any suit or action to recover the Collateral; and (c) any
requirement that Lender retain possession and not dispose of any Collateral
until after trial or final judgment. Borrower and ICC each agree that Lender has
no obligation to preserve rights to the Collateral or marshal any Collateral for
the benefit of any Person. Lender is hereby granted a license or other right to
use, without charge, Borrower's and ICC's labels, patents, copyrights, name,
trade secrets, trade names, trademarks, and advertising matter, or any similar
property, in completing production of, advertising or selling any Collateral,
and Borrower's and ICC's rights under all licenses and all franchise agreements
shall inure to Lender's benefit. The proceeds of sale shall be applied first to
all expenses of sale, including attorneys' fees, and second, in whatever order
Lender elects, to all Obligations. Lender shall return any excess to Borrower
and Borrower and ICC shall remain liable for any deficiency.

            11.2.3. If an Event of Default occurs, Borrower and ICC each hereby
waives all rights to notice and hearing prior to the exercise by Lender of
Lender's rights to repossess the Collateral without judicial process or to
replevy, attach or levy upon the Collateral without notice or hearing.

12.   MISCELLANEOUS.

      12.1. Cumulative Remedies; No Prior Recourse to Collateral.

            The enumeration herein of Lender's rights and remedies is not
intended to be exclusive, and such rights and remedies are in addition to and
not by way of limitation of any other rights or remedies that Lender may have
under the UCC or other applicable law. Lender shall have the right, in its sole
discretion, to determine which rights and remedies are to be exercised and in
which order. The exercise of one right or remedy shall not preclude the exercise
of any others, all of which shall be cumulative. To the extent permitted by law,
Lender may, without limitation, proceed directly against Borrower or ICC to
collect the Obligations without any prior recourse to the Collateral.


                                       32


      12.2. No Implied Waivers.

            No act, failure or delay by Lender shall constitute a waiver of any
of its rights and remedies. No single or partial waiver by Lender of any
provision of this Agreement, or any other Loan Document, or of breach or default
hereunder or thereunder, or of any right or remedy which Lender may have, shall
operate as a waiver of any other provision, breach, default, right or remedy or
of the same provision, breach, default, right or remedy on a future occasion. No
waiver by Lender shall affect its right to require strict performance of this
Agreement except as to the matter waived.

      12.3. Severability.

            Any provision of this Agreement which is prohibited or invalid under
applicable law of any jurisdiction (including without limitation federal or
state regulatory authorities) shall be ineffective to the extent of such
prohibition or unenforceability, without invalidating the remainder of this
Agreement, and any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other
jurisdiction.

      12.4. Governing Law.

            This Agreement shall be deemed to have been made in the State of
Colorado and shall be governed by and interpreted in accordance with the laws of
such state, except that no doctrine of choice of law shall be used to apply the
laws of any other state or jurisdiction and except to the extent that the law of
the location of the Collateral would govern, and in that case that law shall
govern with respect to issues concerning perfection and remedies available with
respect to the Collateral located there only.

      12.5. Consent to Jurisdiction and Venue; Service of Process.

            Borrower and ICC agree that, in addition to any other courts that
may have jurisdiction under applicable laws, any action or proceeding to enforce
or arising out of this Agreement or any of the other Loan Documents may be
commenced in the state court of original jurisdiction of the State of Colorado
for Jefferson County, or in the United States District Court for Colorado, and
Borrower and ICC consent and submit in advance to such jurisdiction, agrees that
venue will be proper in such courts on any such matter and irrevocably waive,
and agree not to plead or claim, any objection that either may ever have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court. Borrower and ICC hereby waive
personal service of process and agrees that a summons and complaint commencing
an action or proceeding in any such court shall be properly served and shall
confer personal jurisdiction if served by registered or certified mail to
Borrower or ICC. Should Borrower or ICC fail to appear or answer any summons,
complaint, process or papers so served within thirty (30) days after the mailing
or other service thereof, it shall be deemed in default and an order or judgment
may be entered against it as demanded or prayed for in such summons, complaint,
process or papers. The choice of forum set forth in this Section 12.5 shall not
be deemed to preclude the enforcement of any judgment obtained in such forum, or
the taking of any action under this Agreement to enforce the same, in any
appropriate jurisdiction.


                                       33


      12.6. Waivers.

            BORROWER AND ICC HEREBY WAIVE TRIAL BY JURY, RIGHTS OF SETOFF, AND
THE RIGHT TO INTERPOSE COUNTERCLAIMS IN ANY LITIGATION IN ANY COURT WITH RESPECT
TO, IN CONNECTION WITH, OR ARISING OUT OF THIS AGREEMENT, THE OTHER LOAN
DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL, OR ANY INSTRUMENT OR DOCUMENT
DELIVERED PURSUANT HERETO OR THERETO, OR ANY OTHER CLAIM OR DISPUTE HOWSOEVER
ARISING, BETWEEN BORROWER OR ICC AND LENDER. BORROWER AND ICC CONFIRM THAT THE
FOREGOING WAIVERS ARE INFORMED AND FREELY MADE.

      12.7. Survival of Representations and Warranties.

            All of Borrower's and ICC's representations and warranties contained
in this Agreement shall survive the execution, delivery, and acceptance thereof
by the parties, notwithstanding any investigation by Lender or its agents.

      12.8. Indemnification.

            Borrower and ICC hereby jointly and severally indemnify, defend and
hold Lender, and its directors, officers, agents, employees and counsel,
harmless from and against any and all losses, claims, damages, liabilities,
expenses, deficiencies, judgments or penalties imposed on, incurred by or
asserted against any of them, whether direct, indirect or consequential, arising
out of or by reason of any litigation, investigations, claims, or proceedings
(whether based on any federal, state or local laws or other statutes or
regulations, including securities, environmental, or commercial laws and
regulations, under common law or at equitable cause, or on contract or
otherwise) commenced or threatened, which arise out of or in any way based upon
the negotiation, preparation, execution, delivery, enforcement, performance or
administration of this Agreement, any other Loan Document, or any undertaking or
proceeding related to any of the transactions contemplated hereby or any act,
omission to act, event or transaction related or attendant thereto, including
amounts paid in settlement, court costs, and the fees and expenses of counsel
reasonably incurred in connection with any such litigation, investigation, claim
or proceeding. Without limiting the foregoing, if, by reason of any suit or
proceeding of any kind, nature, or description against Borrower or ICC, or by
Borrower or ICC or any other party against Lender, which in Lender's sole
discretion makes it advisable for Lender to seek counsel for protection and
preservation of its liens and security assets, or to defend its own interest,
such expenses and counsel fees shall be allowed to Lender. To the extent that
the undertaking to indemnify, pay and hold harmless set forth in this Section
12.8 may be unenforceable because it is violative of any law or public policy,
Borrower and ICC shall contribute the maximum portion which it is permitted to
pay and satisfy under applicable law, to the payment and satisfaction of all
indemnified matters incurred by Lender. The foregoing indemnity shall survive
the payment of the Obligations and the termination of this Agreement. All of the
foregoing costs and expenses shall be part of the Obligations and secured by the
Collateral. 


                                       34


      12.9. Other Security and Guaranties.

            Lender may, without notice or demand and without affecting
Borrower's or ICC's obligations hereunder, from time to time: (a) take from any
Person and hold collateral (other than the Collateral) for the payment of all or
any part of the Obligations and exchange, enforce or release such collateral or
any part thereof; and (b) accept and hold any endorsement or guaranty of payment
of all or any part of the Obligations and release any such endorser or
guarantor, or any Person who has given any Lien in any other collateral as
security for the payment of all or any part of the Obligations, or any other
Person in any way obligated to pay all or any part of the Obligations.

            Whenever an Event of Default exists, Lender is hereby authorized at

other indebtedness at any time owing by Lender or any affiliate of Lender to or
for the credit or the account of Borrower or ICC against any and all of the
