         This AMENDED AND RESTATED OPTION AGREEMENT, dated as of April 13, 2005
(this "Agreement"), is entered into among Boston Scientific Corporation, a
Delaware corporation ("Parent"), Nemo I Acquisition, Inc., a Delaware
corporation and a wholly owned subsidiary of Parent ("Purchaser"), and Richard
J. and Marla A. Linder Family Limited Partnership, a Utah family limited
partnership ("Stockholder").

         WHEREAS, on October 29, 2003, the parties hereto entered into the
original Option Agreement (the "Original Option Agreement"), and the parties
hereto wish to amend and restate the Original Option Agreement in its entirety
as follows;

         WHEREAS, as of the date of this Agreement, Stockholder owns
beneficially and of record the shares (the "Owned Shares") and options (the
"Stock Options") to purchase shares as set forth on Schedule I attached hereto
(such Owned Shares and Stock Options, collectively, the "Stockholder's Equity")
of common stock, par value $.001 per share ("Common Stock"), of Rubicon Medical
Corporation, a Delaware corporation (the "Company");

         WHEREAS, pursuant to an agreement dated July 17, 2003 (the "Term
Sheet") among Parent, the Company, Richard J. Linder ("Linder"), David B. Berger
("Berger") and Berger Family Enterprises, a Utah family limited partnership
("Berger Enterprises"), Parent purchased 2,000,000 shares of the Company's
Common Stock for $2 million in cash (the "First Equity Investment");

         WHEREAS, Parent, Purchaser and the Company entered into a transaction
agreement, originally dated as of October 29, 2003, as amended as of September
30, 2004 (the "Original Transaction Agreement"), and further amended and
restated as of the date hereof (the "Transaction Agreement"; capitalized terms
used herein and not otherwise defined herein shall have the respective meanings
ascribed to such terms in the Transaction Agreement), pursuant to which, among
other things, as of the date of the Original Transaction Agreement, Parent
purchased, and the Company issued to Parent, 1,090,147 shares of Series A
Convertible Preferred Stock for $15 million in cash, which are convertible into
such number of shares of Common Stock that, when aggregated with the Common
Stock issued pursuant to the First Equity Investment, shall constitute 18% of
the Common Stock on a Fully Diluted Basis as of the date of issuance of the
Series A Convertible Preferred Stock;

         WHEREAS, as a condition to the willingness of Parent and Purchaser to
enter into the Original Transaction Agreement, Parent and Purchaser have
requested that Stockholder agree, and, in order to induce Parent and Purchaser
to enter into the Original Transaction Agreement, Stockholder agreed (i) to
grant an option to Parent and Purchaser to purchase the Stockholder's Equity for
a cash purchase price (the "Purchase Option") and (ii) that Parent may require
Stockholder, in lieu of selling its Stockholder's Equity to Parent or Purchaser
as described in clause (i), to tender its Owned Shares into the Offer (as
defined below) in exchange for, at the option of Parent or Purchaser, either
cash or shares of common stock of Parent, par value $0.01 per share ("Parent
Common Stock") (such option, the "Offer Option") (the Purchase Option and the
Offer Option, collectively, the "Options");

         WHEREAS, in the event the Purchase Option is exercised, as soon as
practicable after the closing of the acquisition by Purchaser of the
Stockholder's Equity pursuant to the exercise of the Purchase Option, Purchaser
shall, in accordance with the terms of the Transaction Agreement, commence a
cash tender offer (the "Cash Tender Offer") to acquire all of the issued and
outstanding shares of Common Stock upon the terms and subject to the conditions
of the Transaction Agreement and the Cash Tender Offer; and

         WHEREAS, in the event the Offer Option is exercised, as soon as
practicable after Purchaser gives written notice to each of Stockholder, Linder,
Berger and Berger Enterprises (collectively, the "Controlling Stockholders") of
its exercise of the Offer Option, Purchaser shall commence an exchange offer or
the Cash Tender Offer (either such exchange offer or the Cash Tender Offer, as
the case may be, the "Offer") to acquire all of the issued and outstanding
shares of Common Stock upon the terms and subject to the conditions of the
Transaction Agreement and the Offer.

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants set forth herein and in the Transaction Agreement, the
parties hereto agree as follows:

                                   ARTICLE I
                               THE PURCHASE OPTION

SECTION 1.01. Grant of the Purchase Option. Stockholder hereby grants to Parent
and Purchaser an exclusive and irrevocable option to purchase the Stockholder's
Equity, payable in an amount of cash equal to $1.50 per share of Common Stock,
and, subject to the provisions of Section 1.03, with respect to each Stock
Option, the positive difference between $1.50 and the price per share of Common
Stock for which such Stock Option is exercisable (the "Cash Purchase Price")
(the Cash Purchase Price, together with any rights to receive additional
consideration pursuant to Section 5.03 of the Transaction Agreement, the
"Purchase Option Consideration").

SECTION 1.02. Exercise of the Purchase Option. Provided that (a) to the extent
necessary, any applicable waiting periods (and any extension thereof) under the
HSR Act with respect to the exercise of the Purchase Option shall have expired
or been terminated and (b) no preliminary or permanent injunction or other
order, decree or ruling issued by any Governmental Authority prohibiting the
exercise of the Purchase Option or the delivery of Stockholder's Equity shall be
in effect, Parent or Purchaser may exercise the Purchase Option at any time
during the Option Period with respect to all of the Stockholder's Equity. To
exercise the Purchase Option, Parent or Purchaser shall give written notice (the
date of such notice being herein called the "Notice Date") to Stockholder
specifying a place and date (not later than one Business Day following the
Notice Date) for closing such purchase (the "Closing"). Subject to the delivery
by Stockholder of the documents described in Section 1.04(b), the Closing of the
Purchase Option shall occur as promptly as practicable following the Notice
Date; provided that if the conditions set forth in clause (a) or (b) of the
first sentence of this Section 1.02 have not been satisfied, Parent or Purchaser
may extend the date for the Closing (the "Purchase Option Closing Date") as
necessary for the satisfaction of the conditions set forth in clause (a) or (b)
of the first sentence of this Section 1.02 up to but not exceeding the date that
is 180 days following the Notice Date, after which all rights of Parent and
Purchaser to acquire the Stockholder's Equity in accordance with this Section
1.02 shall terminate.

SECTION 1.03. Vested Options. Stockholder agrees to exercise, upon written
notice from Parent or Purchaser, Stockholder's vested Stock Options upon the
earliest date permitted by the relevant Stock Option Plan. All Stockholder's
Equity resulting from the exercise of such vested options automatically shall
become subject to the Purchase Option that may be exercised by Parent or
Purchaser pursuant to the terms of Section 1.02. Nothing herein shall preclude
Stockholder from exercising Stockholder's vested Stock Options prior to receipt
of notice from Purchaser, and the Stockholder's Equity resulting from such
independent exercise automatically shall become subject to the Options which may
be exercised by Parent or Purchaser pursuant to the terms of this Agreement.

SECTION 1.04. Payment for and Delivery of Certificates. If Parent or Purchaser
elects to exercise the Purchase Option, at the Closing, (a) Parent or Purchaser
shall pay the Purchase Option Consideration for the Stockholder's Equity by wire
transfer in immediately available funds equal to the Cash Purchase Price to an
account designated by Stockholder by written notice to Parent or Purchaser and
(b) Stockholder shall deliver to Purchaser (i) a stock certificate or
certificates evidencing the Owned Shares, (ii) a certificate of a duly
authorized officer of Stockholder certifying that the representations and
warranties of Stockholder contained in this Agreement are true and correct as of
the Closing as if made on the Purchase Option Closing Date, (iii) a certificate
of a duly authorized officer of the Company certifying on behalf of the Company
(with no liability to such officer individually in the absence of fraud or gross
negligence) that the representations and warranties of the Company in the
Transaction Agreement that are qualified as to materiality or Company Material
Adverse Effect are true and correct and the representations and warranties that
are not so qualified are true and correct in all material respects, in each case
as if such representations and warranties were made as of the Purchase Option
Closing Date, and (iv) written evidence, satisfactory to Parent, of the
cancellation of the Stock Options. All such stock certificates evidencing shares
of the Common Stock delivered pursuant to this Section 1.04 shall be duly
endorsed in blank, or with appropriate stock powers, duly executed in blank,
attached thereto, in proper form for transfer, with the signature of Stockholder
thereon guaranteed, and with all applicable taxes paid or provided for.

                                   ARTICLE II
                                THE OFFER OPTION

SECTION 2.01. Tender of the Owned Shares Pursuant to the Offer Option. If Parent
elects to exercise the Offer Option, Stockholder agrees to tender and sell (and
not withdraw prior to termination or expiration of the Offer or the termination
of the Transaction Agreement) its shares of Common Stock and to comply with the
provisions of Section 5.01 of the Transaction Agreement regarding its Stock
Options pursuant to and in accordance with the terms of the Offer and the
Transaction Agreement, as each may be amended from time to time.

SECTION 2.02. Exercise of the Offer Option. Parent or Purchaser may exercise the
Offer Option at any time during the Option Period with respect to all of the
Owned Shares by giving written notice to Stockholder stating that Parent or
Purchaser is exercising the Offer Option. If Parent or Purchaser exercises the
Offer Option, the Offer will be commenced in accordance with the terms and
conditions of the Transaction Agreement.

                                  ARTICLE III
                            OPTION TERM; TERMINATION

SECTION 3.01. Term. Each of the Purchase Option and the Offer Option shall
expire if not exercised prior to the end of the period that commences on the
date of this Agreement and terminates on the calendar day following execution of
the Transaction Agreement (the "Option Period").

SECTION 3.02. Termination. This Agreement shall terminate and be of no further
force and effect if the Transaction Agreement is terminated in accordance with
its terms.

SECTION 8.03. Severability. If any term or other provision of this Agreement is

policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the Options is not affected in any manner materially adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
closely as possible in a mutually acceptable manner in order that the Options be
consummated as originally contemplated to the fullest extent possible.

SECTION 8.04. Entire Agreement. This Agreement and the Transaction Agreement
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersede all prior agreements and undertakings, both written

shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of Shares such amounts as it is
required to deduct and withhold with respect to the making of such payment under
the Code, or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by the Surviving Corporation or Parent, as the case
may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Shares in respect of which
such deduction and withholding was made by the Surviving Corporation or Parent,
as the case may be.

SECTION 8.08. Amendments. This Agreement may not be amended except by an
instrument in writing signed by Parent, Purchaser and Stockholder.

SECTION 8.09. Governing Law. This Agreement shall be governed by, and construed

jurisdiction of any state or federal court sitting in Wilmington, Delaware for
the purpose of any Action arising out of or relating to this Agreement brought
by any party hereto, and (b) irrevocably waive, and agree not to assert by way
of motion, defense, or otherwise, in any such Action, any claim that it is not
