         This Pledge and Security Agreement (the "Agreement"), dated as of

         WHEREAS, the Grantor is also the legal and beneficial owner of certain

loan to the Grantor under that certain $1,209,340 Non-Recourse Note, dated
September 27, 1999 (the "Note"), made by the Grantor to the Company, that the
Grantor execute and deliver a pledge and security agreement in substantially the
form hereof; and

WHEREAS, the Grantor wishes to grant pledges and security interests in the
"Collateral" more particularly described hereinbelow in favor of the Company,
all as herein provided.

         NOW, THEREFORE, in consideration of the premises contained herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

         SECTION 1. Definition of Terms. All capitalized terms not otherwise
defined herein shall have the respective meanings ascribed to such terms in the
Note.

         SECTION 2. Grant of Security Interest. The Grantor hereby pledges and
assigns to the Company and grants to the Company a first priority security
interest in the following (the "Collateral"):

               (i)  the membership interest held by such Grantor in Holdings LLC
         (the "LLC Interests"), as set forth in Schedule A attached hereto and
         incorporated herein, all rights and powers accruing to such LLC
         Interests, whether by contract, statute or operation of law or
         otherwise, all certificates (if any) representing such LLC Interests
         and, subject to the provisions of Section 7 hereof, all dividends,
         cash, instruments and other property (including, without limitation,
         all distributions of capital or alternative securities pursuant to any
         recapitalization, restructuring or dissolution of the Company) from
         time to time received, receivable or otherwise distributed in respect
         of or in exchange for any or all of such LLC Interests; and

               (ii) the shares of capital stock held by such Grantor in the
         Company (collectively, the "Grantor Stock"), also as set forth in
         Schedule A attached hereto and incorporated herein, all rights and
         powers accruing to such Grantor Stock, whether by contract, statute or
         operation of law or otherwise, all securities issued in exchange or
         substitution for such Grantor Stock, all certificates (if any)
         representing such Grantor Stock and, subject to the provisions of
         Section 7 hereof, all dividends, cash, instruments and other property
         (including without limitation all distributions of capital or
         alternative securities pursuant to any recapitalization, restructuring
         or dissolution of the Company) from time to time received, receivable
         or otherwise distributed in respect of or in exchange for any or all of
         such Grantor Stock.

         SECTION 3. Security for Obligations. This Agreement and the security
interest granted hereby are made in order to secure the payment and performance
in full of all payment obligations of the Grantor for principal, interest and
expenses arising under the Note (the "Obligations").

         SECTION 4. Delivery of Collateral. The Grantor has herewith delivered
all certificates or instruments representing or evidencing the Collateral to the
Company, accompanied by duly executed instruments of transfer or assignment in
blank, all in form and substance reasonably satisfactory to the Company. All
additional securities or interests which may hereafter be acquired by the
Grantor and become part of the Collateral shall, if certificated, also be
delivered to the Company in suitable form for transfer and shall be accompanied
by similar executed instruments of transfer or assignments in blank.

         SECTION 5. Representations and Warranties. The Grantor represents and
warrants as follows with respect to the Collateral pledged by such Grantor
pursuant to Section 2 hereof:

               (a) The Grantor has good and marketable title to, and is the
legal and beneficial owner of the Collateral attributable to it as shown on
Schedule A attached hereto, free and clear of any lien, security interest,
option or other charge or encumbrance, except for (i) the restrictions imposed
by the Holdings LLC Limited Liability Company Agreement (the "LLC Agreement"),
dated as of the ICON Restructuring closing, (ii) the Company Stockholders
Agreement (the "Stockholders Agreement"), also dated as of the ICON
Restructuring closing, and (iii) the security interests created by this
Agreement.

               (b) The pledge and assignment of the Collateral to the Company
pursuant to this Agreement creates a valid security interest in the Collateral,
securing the payment of the Obligations. Upon the filing of appropriate
financing statements describing the LLC Interests, such security interest will
be a perfected first priority security interest as to the LLC Interests. Upon
the delivery of the share certificates representing the Grantor Stock,
accompanied by stock powers or other appropriate instruments of assignment
thereof duly executed in blank by the Grantor, such security interest will be a
perfected first priority security interest as to the Grantor Stock.

<PAGE>

               (c) No authorization, consent, approval, or other action by, and
no notice to or filing with any person, including, without limitation, any
governmental authority or regulatory body, is required for (i) the execution and
delivery of, and performance of its obligations under, this Agreement by the
Grantor (except such authorizations, consents, approvals, actions, notices or
filings which have already been obtained).

               (d) The Grantor has full power, authority and legal right to
execute, deliver and perform its obligations under this Agreement and to pledge
and grant a security interest in the Collateral pursuant to this Agreement, and
the execution, delivery and performance hereof and the pledge and assignment of
a security interest in the Collateral hereunder do not contravene any law, rule
or regulation applicable to Grantor, or constitute a violation or breach of any
judgment, decree, contract, agreement or instrument to which the Grantor is a
party or by which it or any of its properties is bound.

               (e) This Agreement is the legal, valid and binding obligation of
the Grantor enforceable against the Grantor in accordance with its terms,
subject to bankruptcy, insolvency and similar laws of general application
affecting the rights and remedies of creditors, equitable principles, and, with
respect to the availability of remedy of specific enforcement, subject to the
discretion of the court before which proceedings therefor may be brought.

               (f) The principal residence of the Grantor is set forth on the
signature page hereto. Grantor will not change the address of its principal
place of residence, unless Grantor has given written notice of any such
alteration or change to the Company no less than ten (10) business days prior
thereto.

         SECTION 6.  Further Assurances. The Grantor agrees that at any time and
from time to time it will promptly execute and deliver all further instruments
and documents, and take all further action, that may be reasonably necessary, or
that the Company may reasonably request, in order to defend the right, title and
security interest of the Company against the claims and demands of others, to
perfect and protect any security interest granted or purported to be granted
hereby or to enable the Company to exercise and enforce its rights and remedies
hereunder with respect to any Collateral.

         SECTION 7.  Voting Rights; Dividends; Etc.

               (a) So long as no Event of Default under the Note shall have
occurred and be continuing:

                      (i)   The Grantor shall be entitled to exercise any and
         all voting and other consensual rights (including without limitation
         all powers of consent, approval, designation and removal) pertaining to
         the Collateral or any part thereof for any purpose not inconsistent
         with the terms of this Agreement or the Note.

                      (ii)  The Company shall execute and deliver (or cause to
         be executed and delivered) to the Grantor all such proxies and other
         instruments as the Grantor may reasonably request for the purpose of
         enabling it to exercise the voting and other rights which the Grantor
         is entitled to exercise pursuant to paragraph (i) above.

                      (iii) The Grantor shall be entitled to receive, retain and
         distribute all regularly scheduled periodic cash dividends on the
         Grantor Stock (including without limitation any portion thereof
         received by Holdings LLC and distributed thereunder) and all regularly
         scheduled periodic cash distributions on the LLC Interests, and, with
         respect to all other cash dividends or other cash distributions upon
         the Collateral at any time (including without limitation any portion
         thereof received by Holdings LLC and distributed thereunder), Grantor
         shall be entitled to receive, retain and distribute only such amount
         thereof as is necessary to pay any federal, state or local taxes of any
         kind required by law to be paid by the Grantor thereon and the
         remainder thereof, together with all other dividends or other
         distributions, shall remain as part of the Collateral pursuant to
         Section 2 hereof.

               (b) Upon the occurrence and during the continuance of an Event of
Default, all rights of the Grantor to exercise the voting and other consensual
rights (including without limitation all powers of consent, approval,
designation and removal) and to receive dividends or distributions which such
Grantor would otherwise be entitled to exercise or receive pursuant to paragraph
(a) above shall cease upon written notice from the Company, and all such rights
shall thereupon become vested in the Company who shall thereupon have the sole
right to exercise such voting and other consensual rights and to receive
dividends or distributions.

         SECTION 8.  Transfers and Other Liens. The Grantor agrees that it will
not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of,
or grant any option with respect to, any of the Collateral, or (ii) create or
suffer to exist any lien, security interest, or other charge or encumbrance upon
or with respect to any of the Collateral to secure indebtedness of any Person,
except as provided in the LLC Agreement and Stockholders Agreement and except
for the security interests created under this Agreement.

         SECTION 9.  Company Appointed Attorney-in-Fact. The Grantor hereby
appoints the Company as its attorney-in-fact, with full authority in the place
and stead of the Grantor and in the name of the Grantor or otherwise, from time
to time in the Company's discretion, to take any action and to execute any
instrument which the Company may deem reasonably necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, to
receive, endorse and collect all instruments made payable to the Grantor
representing any dividend, interest payment or other distribution in respect of
the Collateral or any part thereof and to give full discharge for the same;
provided, however, that the Company shall not have the right to exercise its
power under this Section 9 until the occurrence and continuance of an Event of
Default.

         SECTION 10. Company May Perform. If a Grantor fails to perform any
agreement contained herein within the time provided, the Company may itself
perform, or cause performance of, such agreement, and the reasonable expenses of
the Company incurred in connection therewith shall be payable by the Grantor
under Section 13.

<PAGE>

         SECTION 11. Reasonable Care. The Company shall exercise reasonable care
in the custody and preservation of the Collateral in its possession or control,
it being understood that the Company shall not have any responsibility for (i)
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Collateral, whether or not
the Company has or is deemed to have knowledge of such matters, or (ii) taking
any necessary steps to preserve rights against any parties with respect to any
Collateral. It is agreed that, subject to the foregoing, the Company shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral if the Company exercises the same care that it exercises with respect
to its own property.

         SECTION 12. Remedies upon Event of Default. If any Event of Default
shall have occurred and be continuing:

               (a) The Company may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party under the Uniform
Commercial Code as adopted and in effect in Utah (the "Code"), and, to the
extent permitted by law, the Company may also, without notice except as
specified below, sell the Collateral or any part thereof in one or more parcels
at public or private sale, at any exchange, broker's board or at any of the
Company's offices or elsewhere, for cash, on credit or for future delivery, and
upon such other terms as are commercially reasonable. The Grantor agrees that,
to the extent notice of sale shall be required by law, at least ten (10) days'
notice to the Grantor of the time and place of any public sale or the time after
which any private sale is to be made shall constitute reasonable notification.
The Company shall not be obligated to make any sale of Collateral regardless of
notice of sale having been given. At any such sale, the Company may, to the
extent permitted by the Code or other applicable law, itself purchase all or any
of the Collateral. The Company may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned.

               (b) All cash proceeds received by the Company in respect of any
sale of, collection from, or other realization upon all or any part of the
Collateral may, in the discretion of the Company, be held by the Company as
collateral for, and/or then or at any time thereafter applied (after payment of
any amounts payable to the Company pursuant to Section 13) in whole or in part
by the Company against, all or any part of the Obligations in such order as the
Company shall elect, to the extent permitted by law. Any surplus of such cash or
cash proceeds held by the Company and remaining after payment in full of all the
Obligations shall be paid over to the Grantor or to such other persons as may be
lawfully entitled to receive such surplus.

         SECTION 13. Expenses. The Grantor will upon demand pay to the Company
the amount of any and all reasonable expenses, including the reasonable fees and
expenses of the Company's counsel and of any experts and agents, which the
Company may incur in connection with (i) the administration of this Agreement,
(ii) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (iii) the exercise or enforcement of
any of the rights of the Company hereunder, or (iv) the failure by the Grantor
to perform or observe any of the provisions hereof.

         SECTION 14. Security Interest Absolute. All rights of the Company and
security interests hereunder, and all obligations of the Grantor hereunder,
shall be absolute and unconditional irrespective of:

               (i)   any lack of validity or enforceability of the Note or any
         other agreement or instrument relating thereto;

               (ii)  any change in the time, manner or place of payment of, or
         in any other term of, all or any of the obligations under the Note, or
         any other amendment or waiver of or any consent to any departure from
         the Note;

               (iii) any exchange, release or non-perfection of any other
         collateral, or any release or amendment or waiver of or consent to
         departure from any guaranty, for all or any of the Obligations; or

               (iv)  any other circumstance which might otherwise constitute a
         defense available to, or a discharge of, the Grantor or a third party
         guarantor.

         SECTION 15. Amendments, Etc. No amendment or waiver of any provision of
this Agreement, nor consent to any departure by the Grantor herefrom, shall be
effective unless the same shall be in writing and signed by the Company, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

         SECTION 16. Addresses for Notices. All notices and other communications
provided for hereunder shall be in writing (including communication by
telecopier) and shall be mailed, telecopied or delivered, at the respective
addresses set forth on the signature page hereto, or in any case at such other
address as shall be designated by such party in a written notice to each other
party complying as to delivery with the terms of this section. All such notices
and other communications shall be effective (i) three (3) days after being
deposited in the mails, (ii) when delivered by telecopier (upon electronic
confirmation of receipt thereof) or by hand, or (iii) one (1) business day after
sending by overnight delivery service, addressed as aforesaid.

         SECTION 17. Continuing Security Interest. This Agreement shall create a
continuing security interest in the Collateral and shall (i) remain in full
force and effect until indefeasible cash payment in full of the all obligations,
(ii) be binding upon the Grantor and its successors and assigns, and (iii) inure
to the benefit of the Company and its respective successors, transferees and
assigns. Upon the cash payment in full of the Obligations, the Grantor shall be
entitled to the return, upon its request, of such of the Collateral pledged by
the Grantor as shall not have been sold or otherwise applied pursuant to the
terms hereof.
