Unless sooner terminated pursuant to Section 5 below, the period of Executive's
employment under this Agreement (the "Employment Term") shall be a period of two
years beginning on the Effective Date; provided that, beginning on the first
anniversary of the Effective Date, the Employment Term shall be for a continuous
period of one year, such that on any given date thereafter, the Executive's
Employment Term shall always be one year from the date in question.

3.    DUTIES AND RESPONSIBILITIES.

(a)   Executive shall serve as Executive Vice President and Chief Financial
      Officer of the Company and shall report to the Chief Executive Officer of

      duties of such positions, along with such other duties as may be assigned
      to Executive from time to time by the Chief Executive Officer and/or by

      the Board of Directors of the Company (the "Board of Directors") or a duly
      authorized committee thereof; PROVIDED HOWEVER that Executive shall have
      such responsibility and authority as is normally conferred upon such an
      officer.

      attention during normal business hours to the affairs of the Company and
      use his best efforts to perform faithfully and efficiently his duties and
      responsibilities; PROVIDED, HOWEVER, that subject to the limitations of
      Section 8 hereof and to the prior approval of the Chief Executive Officer
      of the Company, Executive may serve on corporate, industry, civic or
      charitable Boards or committees as long as such activities do not
      interfere with the performance of Executive's responsibilities to the
      Company. Executive agrees to act at all times in the best interests of the
      Company and to take no action or make any statement, oral or written,
      which could reasonably be expected by Executive to injure the Company's
      business, financial condition, results of operations, prospects, interests
      or reputation.

(c)   Executive agrees to comply at all times during the Employment Term with
      all applicable policies, rules, codes and regulations of the Company in

4.    COMPENSATION AND BENEFITS.

(a)   BASE SALARY. During the Employment Term, the Company shall pay Executive a
      base salary at the annual rate of $300,000 USD, or such higher rate as may
      be determined from time to time by the Board of Directors or a duly
      authorized committee thereof (such amount, as increased from time to time,
      the "Base Salary"). Such Base Salary shall be paid on the Company's
      regular pay days in accordance with the Company's standard payroll
      practice for executive officers, subject only to such payroll and
      withholding deductions as may be required by law and other deductions
      applied generally to employees of the Company for insurance and other

      (i)   ANNUAL CASH BONUS. In addition to the Base Salary, Executive shall
            be eligible for an annual cash bonus (either pursuant to a bonus or
            incentive plan or program of the Company or otherwise) for each
            fiscal year during the Employment Term. Executive's target annual
            cash bonus will be equal to 80% (the "Target Bonus Rate") of his
            Base Salary in effect at the beginning of the relevant fiscal year.
            The amount of the annual cash bonus, which may be higher or lower
            than the Target Bonus Rate, shall be determined by the Board of
            Directors or a duly authorized committee thereof based upon
            applicable corporate and individual performance targets established

                                      -2-

            Executive's Annual Bonus shall include any amount which is deferred
            under any nonqualified plan or arrangement of the Company.

      (ii)  LONG-TERM OR SUPPLEMENTAL INCENTIVE COMPENSATION. Executive shall be
            eligible to participate in any supplemental and/or long-term
            incentive compensation plans or programs (which may consist of stock
            options, restricted stock, long-term cash awards or other forms of
            long-term or supplemental incentive compensation) generally made
            available to full-time senior executive officers of the Company.

(c)   BENEFIT PLANS.

      (i)   Executive shall be eligible to participate in and receive benefits
            under all retirement, health and welfare benefit plans, programs and
            arrangements which are from time to time available to full-time
            senior executive officers of the Company in accordance with the
            terms and conditions of such plans, programs and arrangements in
            effect from time to time. Such benefit plans, programs and
            arrangements will include medical, dental and vision benefit plans
            and may include, without limitation, life insurance plans,
            short-term and long-term disability plans, accidental death
            insurance plans, travel accident insurance plans, savings and
            retirement plans and pension plans (all such benefit plans, the
            "Benefit Plans"). Executive agrees to submit to a physical
            examination from time to time as requested by the Company to
            facilitate Executive's participation in one or more Benefit Plans.
            The Company may terminate or reduce benefits under any such plans,
            programs or arrangements to the extent such reductions apply
            uniformly to all full-time senior executive officers of the Company,
            and Executive's benefits shall be reduced or terminated accordingly.
            The Company's obligations under this Section 4(c)(i) are expressly
            conditioned on Executive and his family dependents taking all
            reasonable actions (including but not limited to enrolling in all
            health and welfare benefit programs, plans and arrangements which
            are from time to time available to the Company's full-time senior
            executive officers as and when Executive and his family dependents
            become eligible to participate in such programs, plans and
            arrangements) and providing all information as the Company shall
            reasonably request and as is necessary for the Company to fulfill
            such obligations.

      (ii)  Executive represents that, as of the Effective Date, he is eligible
            under COBRA for the medical, dental and vision insurance benefits
            described on Exhibit B attached hereto (the "COBRA Continuation
            Benefits") under the group health plans of his former employer (the
            "Former Employer") and that he will continue to be eligible for such
            benefits until the end of the COBRA health care continuation period
            under the Former Employer's group health plans (the "COBRA
            Continuation Period"). From the Effective Date until the earlier of
            (A) the end of the COBRA Continuation Period and (B) the date on
            which Executive becomes eligible for a medical, dental and vision
            insurance benefit program of the Company, the Company shall promptly
            reimburse Executive, upon written demand by Executive accompanied by
            supporting invoices, for all premiums charged by the Former Employer
            to Executive for the COBRA Continuation Benefits provided that
            Executive and his family dependents timely and properly elect and

                                      -3-
<PAGE>

            maintain COBRA Continuation Benefits under the Former Employer's
            group health plans throughout such period. The Company's obligations
            under this Section 4(c)(ii) are expressly conditioned on Executive
            and his family dependents taking all reasonable actions (including
            but not limited to satisfying all eligibility conditions under COBRA
            during the COBRA Continuation Period) and providing all information
            as the Company shall reasonably request and as is necessary for the
            Company to fulfill such obligations.

(d)   VACATION. In addition to normal statutory holidays recognized by the
      Company, Executive shall be entitled to the greater of (a) four weeks of
      paid vacation for each fiscal year during the Employment Term and (b) such
      other amount of paid vacation as may be afforded executive officers under
      the Company's policies in effect from time to time ("Vacation Time").

(e)   EXPENSE REIMBURSEMENT. The Company shall promptly reimburse Executive for
      travel and other out-of-pocket expenses incident to his position in
      accordance with the Company's customary practices applicable to full-time
      senior executive officers.

(f)   REIMBURSEMENT OF CERTAIN TAX EXPENSES. The Company shall, upon written
      demand by Executive accompanied by supporting invoices, promptly reimburse
      Executive for all costs and expenses (including reasonable legal,
      accounting and other advisory fees) incurred by Executive to prepare
      responses to an Internal Revenue Service audit of, and to otherwise
      defend, his personal income tax return for any year during the Employment
      Term or to defend himself in any administrative proceeding or civil
      litigation relating to any such tax return, in each case that is
      occasioned by or related to any audit by the Internal Revenue Service of
      the Company's income tax returns; PROVIDED, HOWEVER, in no event shall the
      Company be required to reimburse Executive for costs and expenses in
      excess of seventy-five thousand United States dollars ($75,000 USD) in any
      given fiscal year pursuant to this Section 4(f).

(g)   FRINGE BENEFITS AND PERQUISITES. Executive shall be eligible to
      participate in and receive benefits under all fringe benefit plans,
      practices, policies and programs of the Company to the same extent, and
      subject to the same terms and conditions, as those arrangements are made
      available to full-time senior executive officers of the Company.

(h)   REIMBURSEMENT OF MOVING COSTS. The Company shall reimburse Executive for
      actual and reasonable out-of-pocket costs incurred in Executive's move of
      his household goods from his current residence to the Scottsdale, Arizona
      area. The Company shall also pay Executive an additional payment (the
      "Gross-Up Payment") in an amount which, when combined with the
      reimbursement payments retained by Executive after giving effect to the
      application of federal and state income taxes on the reimbursement amount,
      will result in receipt by Executive of a Gross-Up Payment equal to the
      amount of federal and state income taxes imposed on the reimbursements. If
      within two (2) years after the Effective Date Executive's employment is

                                      -4-
<PAGE>

      terminated by the Company without Cause pursuant to Section 5(f) hereof or
      by Executive for Good Reason pursuant to Section 5(d) hereof, the Company
      shall also reimburse Executive for actual and reasonable out-of-pocket
      costs incurred in Executive's move of his household goods from the
      Scottsdale, Arizona area back to the area of his current residence, and
      shall also make a Gross-Up Payment with respect to any such reimbursement.

5.    TERMINATION OF EMPLOYMENT.

Executive's employment under this Agreement may be terminated under any of the
circumstances set forth in this Section 5. Upon termination, Executive (or his
beneficiaries or estate as the case may be) shall be entitled to receive the
compensation and benefits described in Section 6 and, if applicable, Section 7
below.

(a)   DEATH. Executive's employment hereunder shall terminate automatically upon
      Executive's death.

(b)   TOTAL DISABILITY. The Company may terminate Executive's employment
      hereunder, by written notice to Executive delivered in accordance with
      Sections 5(g) and 16 hereof, upon a determination pursuant to this Section
      5(b) that Executive is "Totally Disabled." For purposes of this Agreement,
      Executive shall be "Totally Disabled" if, in the good faith determination
      of the Board of Directors or a duly authorized committee thereof, based on
      sound medical advice, Executive has become physically or mentally
      incapable of performing the duties and responsibilities assigned to
      Executive under this Agreement without reasonable accommodation and such
      incapability endures for a continuous period of one hundred eighty (180)
      calendar days or an aggregate of one hundred eighty (180) calendar days in
      any calendar year in which event Executive will be considered Totally
      Disabled upon the satisfaction of the applicable one hundred eighty (180)
      day period. Executive's receipt of disability benefits under the Company's
      long-term disability plan shall be deemed conclusive evidence of Total
      Disability for purposes of this Agreement; provided, however, that a
      determination of Total Disability also may be made by the Board of
      Directors or a duly authorized committee thereof as provided above in the
      absence of Executive's receipt of such long-term disability benefits.

(c)   TERMINATION BY THE COMPANY FOR CAUSE. The Company may terminate
      Executive's employment hereunder for "Cause" at any time, by written
      notice to Executive delivered in accordance with Sections 5(g) and 15
      hereof.

            the following: (A) conviction of a crime (including conviction on a
            nolo contendre plea) involving the commission by Executive of a
            felony or of a misdemeanor involving, in the good faith judgment of
            the Board of Directors, fraud, dishonesty or moral turpitude; (B)
            Executive's deliberate and continual refusal to perform the duties
            and responsibilities assigned to Executive under this Agreement
            (other than as a result of vacation permitted under this Agreement,
            sickness, illness or injury); (C) fraud or embezzlement by
            Executive, determined in accordance with the Company's normal,
            internal investigative procedures consistently applied; (D) gross
            misconduct or gross negligence by Executive in connection with the
            business of the Company or an Affiliate (as defined herein) unless
            Executive reasonably believed, in good faith, that his acts or
            omissions were in or not opposed to the best interests of the
            Company (without intent of Executive to gain therefrom, directly or
            indirectly, a profit to which he was not legally entitled); or (E)
            any material breach by Executive of any of the provisions of Section
            8 of this Agreement or of any provisions of the Confidentiality and
            Proprietary Information Agreement (as defined herein).

      (ii)  Any determination of Cause under this Agreement shall be made by
            resolution duly adopted by the affirmative vote of at least
            two-thirds of the members of the Board of Directors (not including
            Executive if Executive is a member of the Board of Directors) at a
            meeting of the Board of Directors called and held for that purpose;
            PROVIDED that Executive shall have been given -------- written
            notice of such meeting by certified mail at least ten (10) business
            days prior to the meeting and shall have been given the opportunity
            to be heard by the Board of Directors before such resolution is
            passed. The failure by the Company to follow the procedures set
            forth in this Section 5(c)(ii) shall result in the termination of
            the Executive's employment being deemed to be a termination by the
            Company without Cause.

(d)   TERMINATION BY EXECUTIVE FOR GOOD REASON. Executive may terminate his
      employment hereunder for Good Reason after delivery by Executive of
      written notice to the Company in accordance with Sections 5(g) and 15

            to any provision of this Section 5 (a "Diminution"); PROVIDED,
            HOWEVER that such Diminution shall not constitute "Good Reason" or a
            "Good Reason Event" if the Company remedies such Diminution within

            reasonable detail the facts and circumstances believed by Executive
            to constitute such Diminution.

      (ii)  A reduction by the Company in Executive's Base Salary.

      (iii) A material breach by the Company of Section 4(b) or 4(c) hereof;
            PROVIDED, HOWEVER that such a breach shall not constitute "Good
            Reason" or a "Good Reason Event" if the Company remedies such breach

            days after Executive makes written demand for such amount.

      (vi)  The failure by the Company to enter into a written agreement with
            any entity that purchases all or substantially all of the assets of
            the Company or any entity into which the Company is merged (each a
            "Successor") pursuant to which such Successor agrees to assume all
            of the obligations of the Company under this Agreement at and
            effective as of the closing of such sale of assets or merger.

(e)   VOLUNTARY TERMINATION BY EXECUTIVE. Executive may terminate his employment

      other than Death pursuant to Section 5(a), Total Disability pursuant to
      Section 5(b) or Cause pursuant to Section 5(c).

            termination as if his employment had continued until the end of such
            period. The Company may purchase insurance to cover all or any part
            of the obligations set forth in this Section 6(b)(i) and Executive
            agrees to submit to a physical examination from time to time to
            facilitate the procurement or renewal of such insurance. Any
            proceeds of such insurance paid to Executive or his beneficiaries or
            estate shall be considered a portion of the payments required to be
            made to Executive pursuant to this Section 6(b)(i) and shall not be
            in addition thereto.

      (ii)  Executive's dependents shall be entitled to continue to receive
            medical, dental and vision insurance coverage at least equal in type
            and amount to that made available to dependents of full-time senior
            executives of the Company immediately prior to Executive's death for
            a period equal to the remainder of the Employment Term from the
            effective date of termination, or until Executive's dependents
            become eligible for employer-provided health insurance benefits from
            any other person or business entity (whether or not those health
            insurance benefits are comparable to the health insurance benefits
            provided by the Company), whichever occurs first. In the event that
            participation in any such plan, program or arrangement of the
            Company is prohibited, the Company will arrange to provide benefits
            substantially similar to those benefits which Executive's dependents
            would have been entitled to receive under such plan, program or
            arrangement for such period.

      (iii) All of Executive's then outstanding options to purchase shares of
            the Company's common stock shall be vested and exercisable in
            accordance with the terms of the stock option plan of the Company
            pursuant to which such options were granted (the "Governing Stock
            Option Plan") as then in effect.

(c)   TERMINATION BY REASON OF TOTAL DISABILITY. In the event that Executive's
      employment is terminated by reason of Executive's Total Disability
      pursuant to Section 5(b) hereof, the Company shall pay Executive the
      following compensation and benefits in addition to the compensation and
      benefits provided for in Section 6(a) above:

      (i)   Subject to Section 6(c)(ii) below, Executive shall be entitled to be
            paid his Base Salary at the rate in effect immediately prior to the
            effective date of termination on the Company's regular pay days for

                                      -9-
<PAGE>

            a period equal to the remainder of the Employment Term from the
            effective date of termination as if his employment had continued
            until the end of such period.

      (ii)  Whenever compensation is payable to Executive under Section 6(c)(i)
            during a period in which he is partially or totally disabled, and
            such disability would (except for the provisions hereof) entitle
            Executive to disability income or salary continuation payments from
            the Company according to the terms of any plan or program presently
            maintained or hereafter established by the Company, the disability
            income or salary continuation paid to Executive pursuant to any such
            plan or program shall be considered a portion of the payments
            required to be made to Executive pursuant to this Section 6(c) and
            shall not be in addition thereto. If disability income is payable
            directly to Executive by an insurance company under the terms of an
            insurance policy paid for by the Company, the amounts paid to
            Executive by such insurance company shall be considered a portion of
            the payment to be made to Executive pursuant to this Section 6(c)
            and shall not be in addition thereto.

      (iii) Executive and his dependents shall be entitled to continue to
            receive medical, dental and vision insurance coverage at least equal
            in type and amount to that made available to full-time senior
            executives of the Company immediately prior to the effective date of
            termination for a period equal to the remainder of the Employment
            Term from the effective date of termination, or until Executive
            becomes eligible for employer-provided health insurance benefits
            from any other person or business entity (whether or not those
            health insurance benefits are comparable to the health insurance
            benefits provided by the Company), whichever occurs first. In the
            event that participation in any such plan, program, or arrangement
            of the Company is prohibited, the Company will arrange to provide
            benefits substantially similar to those benefits which Executive
            would have been entitled to receive under such plan, program, or
            arrangement, for such period.

      (iv)  All of Executive's then outstanding options to purchase shares of
            the Company's common stock shall be vested and exercisable in
            accordance with the terms of the Governing Stock Option Plan, as
            then in effect.

(d)   TERMINATION FOR CAUSE. In the event that Executive's employment is
      terminated by the Company for Cause pursuant to Section 5(c) hereof, the
      Company shall not be obligated to make any payments to Executive under
      this Agreement on or following the effective date of termination, other
      than the compensation and benefits provided for in Section 6(a) above.

(e)   VOLUNTARY TERMINATION BY EXECUTIVE. In the event that Executive terminates
      his employment without Good Reason pursuant to Section 5(e) hereof, the

                                      -10-
<PAGE>

      Company shall not be obligated to make any payments to Executive under
      this Agreement on or following the date of termination, other than the
      compensation and benefits provided for in Section 6(a) above.

(f)   TERMINATION BY THE COMPANY WITHOUT CAUSE OR BY EXECUTIVE FOR GOOD REASON.
      In the event that Executive's employment is terminated by the Company
      without Cause pursuant to Section 5(f) hereof or by Executive for Good
      Reason pursuant to Section 5(d) hereof, the Company shall pay to Executive
      the following compensation and benefits in addition to the compensation
      and benefits provided for in Section 6(a) above:

      (i)   Executive shall be entitled to be paid his Base Salary at the rate
            in effect immediately prior to the effective date of termination on
            the Company's regular pay days for a period equal to the remainder
            of the Employment Term from the effective date of termination as if
            his employment had continued until the end of such period.

      (ii)  Executive and his dependents shall be entitled to continue to
            receive medical, dental and vision insurance coverage at least equal
            in type and amount to that made available to full-time senior
            executives of the Company immediately prior to the effective date of
            termination for a period equal to the remainder of the Employment
            Term from the effective date of termination, or until Executive
            becomes eligible for employer-provided health insurance benefits
            from any other person or business entity (whether or not those
            health insurance benefits are comparable to the health insurance
            benefits provided by the Company), whichever occurs first. In the
            event that participation in any such plan, program or arrangement of
            the Company is prohibited, the Company will arrange to provide
            benefits substantially similar to those benefits which Executive
            would have been entitled to receive under such plan, program or
            arrangement for such period.

      (iii) All of Executive's then outstanding options to purchase shares of
            the Company's common stock shall be vested and exercisable in
            accordance with the terms of the Governing Stock Option Plan, as
            then in effect;

      PROVIDED, HOWEVER, that if the Company terminates Executive's employment
      without Cause or Executive terminates his employment with the Company for
      Good Reason within the one-year period preceding, or within the two-year
      period following, a "Change of Control", Executive shall be paid the
      compensation and benefits provided for in Section 7 hereof rather than the
      compensation and benefits provided for in this Section 6(f).

(g)   NO OTHER BENEFITS OR COMPENSATION. Except as may be provided under this
      Agreement or under the terms of any Compensation Plans or Benefit Plans in
      effect and applicable to Executive on the effective date of termination,
      Executive shall have no right to receive any other compensation, or to
      participate in any other plan, arrangement or benefit after such
      termination and all other obligations of the Company and rights of
      Executive under this Agreement shall terminate effective as of the
      effective date of termination.

      employment with the Company for Good Reason and (ii) a "Change of Control"
      has occurred within the two-year period preceding, or within the one-year
      period following, the effective date of termination, Executive shall be
      entitled to the compensation described in this Section 7 in addition to
      the compensation and benefits provided for in Section 6(a) above and in
      lieu of the compensation and benefits provided for in Section 6(f) above:

            becomes eligible for employer-provided health insurance benefits

            health insurance benefits are comparable to the health insurance
            benefits provided by the Company), whichever occurs first. In the
            event that participation in any such plan, program, or arrangement
            of the Company is prohibited, the Company will arrange to provide
            benefits substantially similar to those benefits which Executive

            Company is not the surviving entity or becomes owned entirely by
            another entity, unless at least 50% of the outstanding voting
            securities of the surviving or parent corporation, as the case may
            be, immediately following such transaction are beneficially held by
            the same persons and/or entities that beneficially held the
            outstanding voting securities of the Company immediately prior to
            such transaction, and such outstanding voting securities are
            beneficially held by such persons and/or entities in the same

            such transaction;

      (iii) the acquisition of beneficial ownership, as such term is defined in

            offer or otherwise), of more than 50% of the voting securities of
            the Company by a single person or entity (other than the Company or
            any affiliate (as such term is defined in Rule 12b-2 under the
            Exchange Act) of the Company (each an "Affiliate"), a trustee or any
            other fiduciary or committee of any employee benefit plan of the
            Company, or any corporation owned, directly or indirectly, by the
            stockholders of the Company in substantially the same proportions as
            their ownership of the stock of the Company) or "group" within the
            meaning of Section 13(d)(3) of the Exchange Act, whether through the
            acquisition of previously issued and outstanding voting securities
            or of voting securities that have not been previously issued, or any
            combination thereof;

            Certificate of Designations of the Powers, Preferences and other
            Special Rights of the Series A Preferred Stock and the
            Qualifications, Limitations and Restrictions Thereof shall be
            considered, for purposes of this Agreement, a member of the
            Incumbent Board; and provided further that, notwithstanding anything
            herein to the contrary, a Change of Control shall not be deemed to
            have occurred in connection with (i) any public offering of the
            common stock of the Company for cash; (ii) any transaction with an
            entity or group that includes, is affiliated with or is wholly or
            partially controlled by, one or more executive officers of the

            otherwise constitute a Change of Control; (iii) any capital raising

                                      -13-

      hereof at a time when a Change of Control occurs, such payments shall be
      deducted from the lump sum payment required to be made to Executive
      pursuant to Section 7(a)(i) hereof.

      the Company may have against Executive.

(b)   RIGHT TO INJUNCTION. Executive acknowledges that a breach of the covenants
      set forth in Section 8 hereof will cause irreparable damage to the Company
      with respect to which the Company's remedy at law for damages will be
      inadequate. Therefore, in the event of a breach of the covenants set forth
      in Section 8 by Executive or if the Company has reasonable grounds to
      believe that a breach by Executive of the covenants set forth in Section 8

                                      -16-
<PAGE>

      is imminent, Executive and the Company agree that the Company shall be
      entitled to the following particular forms of relief, in addition to
      remedies otherwise available to it at law or in equity; (i) injunctions,
      both preliminary and permanent, enjoining or restraining such breach or
      anticipatory breach and Executive hereby consents to the issuance thereof
      forthwith and without bond by any court of competent jurisdiction; and
      (ii) recovery of all reasonable sums expended and costs, including
      reasonable attorney's fees, incurred by the Company to enforce the
      covenants set forth in Section 8.

(c)   SEPARABILITY OF COVENANTS. The covenants contained in Section 8 hereof
      constitute a series of separate covenants, one for each applicable State
      in the United States and the District of Columbia, and one for each
      province and Territory in Canada. If in any judicial proceeding, a court
      shall hold that any of the covenants set forth in Section 8 exceed the
      time, geographic, or occupational limitations permitted by applicable
      laws, Executive and the Company agree that such provisions shall and are
      hereby reformed to the maximum time, geographic, or occupational
      limitations permitted by such laws. Further, in the event a court shall
      hold unenforceable any of the separate covenants deemed included herein,
      then such unenforceable covenant or covenants shall be deemed eliminated
      from the provisions of this Agreement for the purpose of such proceeding
      to the extent necessary to permit the remaining separate covenants to be
      enforced in such proceeding. Executive and the Company further agree that
      the covenants in Section 8 shall each be construed as a separate agreement
      independent of any other provisions of this Agreement, and the existence
      of any claim or cause of action by Executive against the Company, whether
      predicated on this Agreement or otherwise, shall not constitute a defense
      to the enforcement by the Company of any of the covenants of Section 8.

10.   MITIGATION OF DAMAGES; ATTORNEY'S FEES

            (a) Executive shall not be required to mitigate the amount of any
payment provided for in this Agreement by seeking other employment.

            (b) If any legal action is filed by either party to enforce or
interpret any of the provisions of this Agreement, the losing party shall pay to
the prevailing party, in addition to any other amounts awarded in the action,
all reasonable attorney's fees and other fees and costs incurred by the
prevailing party in connection with such legal action, the amount of which shall
be fixed by the court hearing such action and made a part of any judgment
rendered.

11.   WITHHOLDING OF TAXES.

The Company may withhold all applicable taxes from any compensation and benefits
payable under this Agreement.

                                      -17-

12.   ASSIGNMENT.

Except as otherwise provided in this Agreement, this Agreement shall inure to
the benefit of, and be binding upon, the parties hereto and their respective
heirs, representatives, successors and permitted assigns. The rights, benefits
and obligations of Executive under this Agreement are personal to Executive and
no such right, benefit or obligation shall be subject to voluntary or
involuntary alienation, assignment or transfer; PROVIDED, HOWEVER, that nothing
in this Section 12 shall preclude Executive from designating a beneficiary or
beneficiaries to receive any benefit payable on his death. The Company shall
require any Successor (whether by purchase of all or substantially all of the
assets of the Company or by merger of the Company into another entity) to assume
and agree to perform this Agreement in the same manner and to the same extent
that the Company would have been required to perform if no such succession had
taken place. Upon any such assignment, all references herein to the Company
shall be deemed to refer to such assignee.

13.   ENTIRE AGREEMENT; AMENDMENT.

This Agreement, together with all schedules, exhibits and other documents
referred to herein, shall supersede any and all existing oral or written
agreements, representations, or warranties between Executive and the Company
relating to the terms of Executive's employment by the Company. This Agreement
may not be amended, nor any provision waived, except by a written instrument
signed by the party against whom such amendment or waiver is sought to be
enforced.

14.   GOVERNING LAW; JURISDICTION.

This Agreement shall be governed by and construed in accordance with the
internal substantive laws of the State of Delaware, without giving effect to the
conflict of law principles thereof. The parties agree that all disputes, legal
actions, suits and proceedings arising out of or relating to this Agreement or
Executive's employment with the Company must be brought exclusively in a federal
district court or state court located in Maricopa County, Arizona. Each party
hereby irrevocably consents and submits to the exclusive jurisdiction of such
courts. No legal action, suit or proceeding with respect to this Agreement or
Executive's employment with the Company may be brought in any other forum. Each
party hereby irrevocably waives all claims of immunity from jurisdiction and any
right to object on the basis that any dispute, action, suit or proceeding
brought in any such court has been brought in an improper or inconvenient forum
or venue.

15.   NOTICES.

Any notice, consent, request or other communication made or given in connection
with this Agreement shall be in writing and shall be deemed to have been duly
given if delivered personally, mailed by registered or certified mail (return

16.   MISCELLANEOUS.

(a)   WAIVER. The failure of a party to insist upon strict adherence to any term
      of this Agreement on any occasion shall not be considered a waiver thereof
      or deprive that party of the right thereafter to insist upon strict
      adherence to that term or any other term of this Agreement. The waiver by
      any party hereto of a breach of any provision of this Agreement shall
      neither operate nor be construed as a general waiver or as a specific
      waiver of any subsequent breach by any party, unless otherwise expressly
      provided in such waiver.

(b)   SEPARABILITY. Subject to Section 9 hereof, if any term or provision of
      this Agreement or application thereof to anyone or under any circumstances
      shall be determined to be invalid, illegal or unenforceable by any court
      of competent jurisdiction and cannot be modified to be enforceable, such
      term or provision shall immediately become null and void, leaving the
      remainder of this Agreement in full force and effect.

(c)   HEADINGS. Section headings are used herein for convenience of reference
      only and shall not affect the meaning of any provision of this Agreement.

(d)   RULES OF CONSTRUCTION. Whenever the context so requires, the use of the
      singular shall be deemed to include the plural and vice versa.

(e)   COUNTERPARTS. This Agreement may be executed in any number of
      counterparts, each of which so executed shall be deemed to be an original,
      and such counterparts will together constitute but one Agreement.

(f)   COOPERATION. Following termination of employment for any reason, Executive
      agrees that he will cooperate fully with the Company and its counsel with
      respect to any matter (including, without limitation, litigation or
      governmental proceedings) with which Executive was involved during his
      term of employment with the Company. Executive will be available to
      perform such services on a reasonable basis to the extent requested by the
      Company. The Company agrees to cooperate with Executive in scheduling such
      services to minimize disruption of any new employment relationship which
      Executive may have commenced. Subject to the foregoing sentence, Executive
      shall render such cooperation in a timely manner on reasonable notice from
      the Company, and agrees to travel as reasonably requested by the Company
      in connection with performing such services. The Company will reimburse
      Executive's reasonable out-of-pocket expenses incurred in connection with
      providing such services in accordance with the Company's policies as in
      effect from time to time.

(g)   RELEASE. Notwithstanding anything herein to the contrary, the Company
      shall not be required to make any of the payments, or provide any of the
      benefits, to the Executive pursuant to Sections 6 or 7 hereof unless and
      until Executive executes and delivers a release of all claims arising out
      of Executive's employment or termination through the date of the release,
      but excluding claims for indemnification from the Company under the
      Indemnification Agreement attached hereto as Exhibit A, which release
      shall be in a form satisfactory to the Company in its sole discretion.

(h)   SURVIVAL. Notwithstanding anything in this Agreement to the contrary, the
      provisions of Sections 8, 9, 10, 14, 15 and 16 shall survive any
      termination of Executive's employment in accordance with their respective
      terms.

17.   GUARANTEE. Capital hereby guarantees the performance by the Company of the
      Company's obligations under this Agreement; PROVIDED, HOWEVER, that this
      guarantee shall terminate and be of no further force or effect upon
      consummation of the U.S. Reorganization Transaction.

                  shall include any amount which is deferred under any
                  nonqualified plan or arrangement of the Company.

                  (ii)     ANNUAL CASH PERFORMANCE BONUS. In addition to Base
                           Salary, Employee shall be eligible for an annual cash
                           bonus for each fiscal year of the Company during the
                           Term. Employee's target annual cash bonus will be
                           equal to 60% of his Base Salary in effect at the

                           Financial Officer, based upon satisfaction of annual
                           performance objectives as fixed from time to time by
                           the Executive Vice-President, Chief Financial
                           Employee's Annual Bonus shall include any amount
                           which is deferred under any nonqualified plan or
                           arrangement of the Company.

                  (iii)    BENEFIT PLANS. Employee and his dependants shall be
                           eligible to participate in and receive benefits under
                           standard group insurance benefits made available to
                           other similarly situated employees of the Company,
                           and such other benefits as may become available from
                           time to time. Such benefits will include dental,

                           such benefits, the "Benefit Plans"). Employee agrees
                           to submit to a physical examination from time to time
                           as requested by the Company to facilitate Employee's
                           participation in one or more Benefit Plans. The
                           Company may terminate or reduce benefits under any
                           Benefit Plans to the extent such reductions apply
                           uniformly to all full-time, similarly situated
                           employees, and Employee's benefits shall be reduced
                           or terminated accordingly. The Company's obligations
                           under this section 3 (b) (iii) are expressly
                           conditioned on Employee and his family dependents
                           taking all reasonable actions (including but not
                           limited to enrolling in all health and welfare
                           benefit programs, plans and arrangements which are
                           from time to time available to similarly situated
                           Officer. For all purposes under this Agreement,

                                      -3-
<PAGE>

                           employees of the Company as and when Employee and his
                           family dependents become eligible to participate in
                           such programs, plans and arrangements) and providing
                           all information as the Company may reasonably request
                           and is necessary for the Company to fulfill such
                           obligations.

                  (iv)     CAR. WSI shall provide the Employee with a leased

                           with his position.

                  (v)      VACATION. In addition to usual statutory holidays
                           recognized by the Company, Employee shall be entitled
                           to four (4) weeks of paid vacation in each fiscal
                           year, to be taken at such times as mutually agreed
                           between the Employee and the person to whom Employee
                           reports. Vacation may only be taken within the year
                           of entitlement and may not be accumulated from year
                           to year unless otherwise mutually agreed.

         (c)      EXPENSES. Employee shall be reimbursed for all expenses
                  reasonably and actually incurred in the performance of his
                  duties, subject to submission of appropriate documentation in
                  accordance with the Company's expense reimbursement policy in
                  effect from time to time.

         (d)      MOVING COSTS. The Company shall reimburse Employee for actual
                  and reasonable out-of-pocket costs incurred in Employee's move
                  of his household goods from his current residence to the
                  Scottsdale, Arizona area. The Company shall also pay Employee
                  an additional payment (the "Gross-Up Payment") in an amount
                  which, when combined with the reimbursement payments retained
                  by Employee after giving effect to the application of federal
                  and state income taxes on the reimbursement amount, will
                  result in receipt by Employee of a Gross-Up Payment equal to
                  the amount of federal and state income taxes imposed on the
                  reimbursements. If within one (1) year after the date hereof
                  Employee's employment is terminated by the Company without
                  cause, the Company shall also reimburse Employee for actual
                  and reasonable out-of-pocket costs incurred in Employee's move
                  of his household goods from the Scottsdale, Arizona area back
                  to the area of his current residence, and shall also make a
                  Gross-Up Payment with respect to any such reimbursement.

5.       TERMINATION OF EMPLOYMENT

         Employee's employment under this Agreement may be terminated under any
         of the circumstances set forth in this Section 5. Upon termination,
         Employee (or his beneficiaries or estate, as the case may be) shall be
         entitled to receive the compensation and benefits described under
         Section 6 below.

         (a)      DEATH. Employee's employment hereunder shall terminate
                  automatically upon Employee's death.

         (b)      TOTAL DISABILITY. The Company may terminate Employee's
                  employment hereunder, by written notice to Employee delivered
                  in accordance with Section 15 hereof, upon a determination
                  pursuant to this section 5 (b) that the Employee is "Totally
                  Disabled". For purposes of this Agreement, Employee shall be
                  "Totally Disabled" if Employee is physically or mentally
                  incapacitated so as to render Employee incapable of performing
                  his usual and customary duties under this Agreement for a
                  continuous period of one hundred and eighty (180) days or an
                  aggregate total of one hundred and eighty days (180) days in

                                      -4-
<PAGE>

                  any calendar year. Employee's receipt of disability benefits
                  under the Company's long-term disability plan or receipt of
                  other disability benefits shall be deemed conclusive evidence
                  of Totally Disabled for the purposes of this Agreement;
                  PROVIDED HOWEVER, in the absence of Employee's receipt of such
                  long-term disability benefits or other disability benefits,
                  the Company may, in its reasonable discretion (but based upon
                  appropriate medical evidence) determine that Employee is
                  Totally Disabled.

         (c)      TERMINATION BY THE COMPANY FOR CAUSE. Employee's employment
                  hereunder may be terminated by the Company for "Cause". For
                  purposes of this Agreement, the term "Cause" shall mean any of
                  the following: (A) conviction of a crime (including conviction
                  on a nolo contendre plea) involving the commission by Employee
                  of a felony or of a misdemeanor involving, in the good faith
                  judgment of the Board of Directors, fraud, dishonesty or moral
                  turpitude; (B) Employee's deliberate and continual refusal to
                  perform the duties and responsibilities assigned to Employee
                  under this Agreement (other than as a result of vacation
                  permitted under this Agreement, sickness, illness or injury);
                  (C) fraud or embezzlement by Employee, determined in
                  accordance with the Company's normal, internal investigative
                  procedures consistently applied; (D) gross misconduct or gross
                  negligence by Employee in connection with the business of the
                  Company or an Affiliated Corporation (as defined herein)
                  unless Employee reasonably believed, in good faith, that his
                  acts or omissions were in or not opposed to the best interests
                  of the Company (without intent of Employee to gain therefrom,
                  directly or indirectly, a profit to which he was not legally
                  entitled); or (E) any material breach by Employee of any of
                  the provisions of Section 8 of this Agreement or of any
                  provisions of the Confidentiality and Proprietary Information
                  Agreement (as defined herein). The Company shall provide the
                  Employee with written notice setting forth in reasonable
                  detail the facts and circumstances deemed to provide the basis
                  for termination of the Employee's employment for Cause at the
                  time of such termination.

         (d)      TERMINATION BY THE COMPANY WITHOUT CAUSE. At any time during
                  the Term, the Company may terminate Employee's employment
                  hereunder without Cause by written notice to Employee
                  delivered in accordance with Section 15 hereof. For purposes
                  of this Agreement, Employee's employment shall be deemed to
                  have been terminated "Without Cause" if Employee is terminated
                  by the Company for any reason other than Death pursuant to
                  Section 5 (a), Total Disability pursuant to Section 5 (b) or
                  Cause pursuant to Section 5 (c).

         (e)      VOLUNTARY TERMINATION BY EMPLOYEE. Employee may terminate his
                  employment hereunder at any time during the Term after
                  providing not less than thirty (30) days' written notice to
                  the Company delivered in accordance with Section 15 hereof.

         (f)      TERMINATION BY EMPLOYEE FOR GOOD REASON. Employee may
                  terminate his employment hereunder for Good Reason after
                  delivery by Employee of written notice to the Company in
                  accordance with Section 15 hereof within sixty (60) days after
                  the occurrence of a Good Reason Event (as hereinafter
                  defined). For purposes of this Agreement, "Good Reason" means
                  the occurrence of any of the following events (each a "Good
                  Reason Event") without written consent during the Term:

                  (i)      A change in Employee's responsibilities or titles or
                           any other action by the Company which represents a
                           material diminution of Employee's position, status or
                           authority, except in connection with or as a result
                           of the termination of Employee's employment pursuant
                           to any provision of this Section 5 (a "Dimunition");
                           PROVIDED, HOWEVER that such Dimunition shall not
                           constitute "Good Reason" or a "Good Reason Event" if
                           the Company remedies such Dimunition within ten (10)
                           business days after delivery by Employee of written
                           notice to the Company in accordance with Section 15
                           hereof specifying in reasonable detail the facts and
                           circumstances believed by Employee to constitute such
                           Dimunition.

                  (ii)     A reduction by the Company in Employee's Base Salary.

                  (iii)    A material breach by the Company of Section 4(b)(ii)
                           or (iii) hereof; PROVIDED, however that such a breach
                           shall not constitute "Good Reason" or a "Good Reason
                           Event" if the Company remedies such breach within ten
                           (10) business days after delivery by Employee of
                           written notice to the Company in accordance with
                           Section 15 hereof specifying in reasonable detail the
                           facts and circumstances believed by Employee to
                           constitute a material breach of Section 4(b)(ii) or
                           (iii).

                  (iv)     A change of Employee's principal place of employment
                           to a location outside the Phoenix/Scottsdale
                           metropolitan area.

                  (v)      The failure by the Company to pay Employee any
                           material amount of his Base Salary, or any material
                           amount of other compensation, that is due and payable
                           under this Agreement within ten (10) business days
                           after Employee makes written demand for such amount.

                  (vi)     The failure by the Company to enter into a written
                           agreement with any entity that purchases all or
                           substantially all of the assets of the Company or any
                           entity into which the Company is merged (each a

                           "Successor") pursuant to which such Successor agrees
                           to assume all of the obligations of the Company under
                           this Agreement at and effective as of the closing of
                           such sale of assets or merger.

6.       COMPENSATION AND BENEFITS FOLLOWING TERMINATION OF EMPLOYMENT.

         If Employee's employment is terminated, Employee shall be entitled to
         the following compensation and benefits:

         (a)      COMPENSATION AND BENEFITS PAYABLE FOLLOWING TERMINATION FOR
                  ANY REASON. The following compensation shall be payable upon
                  termination of Employee's employment under this Agreement for
                  any reason:

                  (i)      Employee or his beneficiaries or estate shall be
                           entitled to receive, within fourteen (14) days after
                           the effective date of termination, any accrued but
                           unpaid Base Salary for services rendered by Employee
                           to the Company prior to the date of termination, any
                           accrued but unpaid expenses required to be reimbursed
                           under this Agreement, and cash compensation (at a
                           rate per day equal to Base Salary divided by the
                           number of business days in the relevant year) for any
                           accrued Vacation Time that remained unused by the
                           Employee at the time of termination; and

                  (ii)     Any earned benefits to which Employee (or his
                           beneficiaries or estate) may be entitled pursuant to
                           the Benefit Plans shall be determined and paid in
                           accordance with the terms of such plans, policies and
                           arrangements. In the case of compensation previously
                           deferred by Employee, all amounts previously deferred
                           and not yet paid by the Company shall be paid to
                           Employee within fourteen (14) days after the
                           effective date of termination unless such payment is
                           inconsistent with the terms of any payment election
                           made by Employee with respect to such deferred
                           compensation.

         (b)      TERMINATION ON DEATH. If Employee's employment is terminated
                  by reason of Employee's death, pursuant to Section 5(a)
                  hereof, the Company shall pay the Employee's estate or
                  beneficiaries the following compensation and benefits in
                  addition to the compensation and benefits provided pursuant to
                  Section 6(a) above.

                  (i)      Employee shall be entitled to be paid his Base Salary
                           at the rate in effect immediately prior to the
                           effective date of termination on the Company's
                           regular pay days for a period equal to the remainder
                           of the Term from the effective date of termination as
                           if employment had continued until the end of such
                           period; and

                  (ii)     Employee's dependents shall be entitled to continue
                           to receive medical, dental and vision insurance

                           coverage at least equal in type and amount to that
                           made available to similarly situated employees of the
                           Company immediately prior to the effective date of
                           termination for a period equal to the remainder of
                           the Term from the effective date of termination, or
                           until Employee's dependents become eligible for
                           employer-provided health insurance benefits from any
                           other person or business entity (whether or not those
                           health insurance benefits are comparable to the
                           health insurance benefits provided by the Company)
                           whichever occurs first. If participation in any such
                           plan, program or arrangement of the Company is
                           prohibited, the Company will arrange to provide
                           benefits substantially similar to those benefits
                           which Employee would have been entitled to receive
                           under such plan, program or arrangement for such
                           period.

                  (iii)    All of the Employees then outstanding options to
                           purchase common shares of Capital or the Company, as
                           the case may be, shall be vested and exercisable in
                           accordance with the terms of the Company or Capital's
                           Employee Stock Option Plan pursuant to which such
                           options were granted.

         (c)      TERMINATION ON TOTAL DISABILITY. If Employee's employment is
                  terminated by reason of Employee's Total Disability, pursuant
                  to Section 5(b) hereof, the Company shall pay the Employee the
                  following compensation and benefits in addition to the
                  compensation and benefits provided pursuant to Section 6(a)
                  above.

                  (i)      Subject to Section 6(c)(ii) below, Employee shall be
                           entitled to be paid his Base Salary at the rate in
                           effect immediately prior to the effective date of
                           termination on the Company's regular pay days for a
                           period equal to the remainder of the Term from the
                           effective date of termination as if employment had
                           continued until the end of such period; and

                  (ii)     Whenever compensation is payable to Employee under
                           Section 6(c)(i) during a period in which he is
                           partially or totally disabled, and such disability
                           would (except for the provisions hereof) entitle
                           Employee to disability income or salary continuation
                           payments from the Company according to the terms of
                           any plan or program presently maintained or hereafter
                           established by the Company, the disability income or
                           salary continuation paid to Employee pursuant to any
                           such plan or program shall be considered a portion of
                           the payments required to be made to Employee pursuant
                           to this Section 6(c) and shall not be in addition
                           thereto. If disability income is payable directly to
                           Employee by an insurance company under the terms of
                           an insurance policy paid for by the Company, the

                  FOR GOOD REASON. If Employee's employment is terminated by the
                  Company without Cause pursuant to Section 5(c) hereof or by

                           prohibited, the Company will arrange to provide
                           benefits substantially similar to those benefits
                           which Employee would have been entitled to receive
                           under such plan, program or arrangement for such
                           period.

                  (iii)    All of the Employees then outstanding options to

                         making or publishing of written or oral statements or
                         remarks (including, without limitation, the repetition
                         or distribution of derogatory rumors, allegations,
                         negative reports or comments) which are disparaging,
                         deleterious or damaging to the integrity, reputation or
                         goodwill of the Company, or Capital or any Affiliated

                         deleterious or damaging to the integrity or reputation
                         of Employee.

         (d)      PROTECTED INFORMATION. Employee recognizes and acknowledges
                  that Employee has had and will continue to have access to
                  various confidential and proprietary information concerning

                                      -11-
<PAGE>

                  the Company, Capital and the Affiliated Corporations which is
                  of a special and unique value. As a condition to commencement
                  of Employee's employment hereunder, Employee shall execute a
                  Confidentiality and Proprietary Rights Agreement in
                  substantially the form of Exhibit B attached hereto (the
                  "Confidentiality and Proprietary Rights Agreement"). Any
                  breach by Employee of the Confidentiality and Proprietary
                  Rights Agreement shall be considered a breach of this
                  Agreement.

         (e)      NON-COMPETE PERIOD. For purposes of this Agreement, the term
                  "Non-Compete Period" shall have the following meanings:

                           Section 5(d), the Non-Compete Period shall mean the
                           period beginning on the effective date of termination
                           and ending on the last date on which Employee
                           receives cash compensation pursuant to Section 6(f)
                           above.

                  (ii)     In the event Employee's employment hereunder is
                           terminated by the Company with Cause pursuant to
                           Section 5(c), or by Employee voluntarily pursuant to
                           Section 5(e), the Non-Compete Period shall mean the
                           period beginning on the effective date of termination
                           and ending on the first anniversary of the effective
                           date of termination.

                  (iii)    In the event Employee's employment hereunder is
                           terminated by the Company upon Death of Employee
                           pursuant to Section 5(a) or Total Disability of
                           Employee pursuant to Section 5(b), there shall be no
                           Non-Compete Period.

8.       ENFORCEMENT OF COVENANTS.

         (a)      TERMINATION OF EMPLOYMENT AND FORFEITURE OF COMPENSATION.
                  Notwithstanding anything in this Agreement to the contrary, in
                  the event that the Company determines in its good faith
                  judgment that Employee has violated Sections 7(a) or 7(b)
                  hereof, the Company shall have the right to suspend or
                  terminate any or all remaining payments or benefits payable
                  pursuant to Section 6 of this Agreement. Such suspension or
                  termination of benefits shall be in addition to and shall not
                  limit any and all other rights and remedies that the Company
                  may have against Employee.

         (b)      RIGHT TO INJUNCTION. Employee acknowledges that a breach of
                  the covenants set forth in Section 7 hereof will cause
                  irreparable damage to the Company with respect to which the
                  Company's remedy at law for damages will be inadequate.
                  Therefore, in the event of a breach of the covenants set forth
                  in Section 7 by Employee or if the Company has reasonable
                  grounds to believe that a breach by Employee of the covenants
                  set forth in Section 7 is imminent, Employee and the Company
                  agree that the Company shall be entitled to the following
                  particular forms of relief, in addition to remedies otherwise
                  available to it at law or in equity; (i) injunctions, both
                  preliminary and permanent, enjoining or restraining such
                  breach or anticipatory breach and

                                      -12-
<PAGE>
                  Employee hereby consents to the issuance thereof forthwith and
                  without bond by any court of competent jurisdiction; and (ii)
                  recovery of all reasonable sums expended and costs, including
                  reasonable attorney's fees, incurred by the Company to enforce
                  the covenants set forth in Section 7. If participation in any
                  such plan, program or arrangement of the Company is
                  prohibited, the Company will arrange to provide benefits
                  substantially similar to those benefits which Employee would
                  have been entitled to receive under such plan, program or
                  arrangement for such period.

         (c)      SEPARABILITY OF COVENANTS. The covenants contained in Section
                  7 hereof constitute a series of separate covenants, one for
                  each applicable State in the United States and the District of
                  Columbia, and one for each province and Territory in Canada.
                  If in any judicial proceeding, a court shall hold that any of
                  the covenants set forth in Section 7 exceed the time,
                  geographic, or occupational limitations permitted by
                  applicable laws, Employee and the Company agree that such
                  provisions shall and are hereby reformed to the maximum time,
                  geographic, or occupational limitations permitted by such
                  laws. Further, in the event a court shall hold unenforceable
                  any of the separate covenants deemed included herein, then
                  such unenforceable covenant or covenants shall be deemed
                  eliminated from the provisions of this Agreement for the
                  purpose of such proceeding to the extent necessary to permit
                  the remaining separate covenants to be enforced in such
                  proceeding. Employee and the Company further agree that the
                  covenants in Section 7 shall each be construed as a separate
                  agreement independent of any other provisions of this
                  Agreement, and the existence of any claim or cause of action
                  by Employee against the Company, whether predicated on this
                  Agreement or otherwise, shall not constitute a defense to the
                  enforcement by the Company of any of the covenants of Section
                  7. If participation in any such plan, program or arrangement
                  of the Company is prohibited, the Company will arrange to
                  provide benefits substantially similar to those benefits which
                  Employee would have been entitled to receive under such plan,
                  program or arrangement for such period.

9.       ATTORNEY'S FEES.

         If any legal action is filed by either party to enforce or interpret
         any of the provisions of this Agreement, the losing party shall pay to
         the prevailing party, in addition to any other amounts awarded in the
         action, all reasonable attorney's fees and other fees and costs
         incurred by the prevailing party in connection with such legal action,
         the amount of which shall be fixed by the court hearing such action and
         made a part of any judgment rendered.

10.      WITHHOLDING OF TAXES.

         The Company may withhold all applicable taxes from any compensation and
         benefits payable under this Agreement.

         all previous oral or written agreements or representations respecting
         or relating in any way to the Employee's employment including but not
         limited to its terms and conditions. It is further agreed that this

         that all disputes, legal actions, suits and proceedings arising out of
         or relating to this Agreement or Employee's employment with the Company
         must be brought exclusively in a federal district court or state court
         located in Maricopa County, Arizona. Each party hereby irrevocably
         consents and submits to the exclusive jurisdiction of such courts. No.
         legal action, suit or proceeding with respect to this Agreement or
         Employee's employment with the Company may be brought in any other
         forum. Each party hereby irrevocably waives all claims of immunity from
         jurisdiction and any right to object on the basis that any dispute,
         action, suite or proceeding brought in any such court has been brought
         in an improper or inconvenient forum or venue.

13.      ASSIGNMENT

         The Employee acknowledges that WSI may assign this Agreement to Capital
         or any of the Affiliated Corporations, to any corporation with which
         they are merged or amalgamated, or to any third party acquiring all or
         part of any of the businesses of WSI or Capital provided that the
         Company shall require any Successor (whether by purchase of all or
         substantially all of the assets of the Company or by merger of the
         Company into another entity) to assume and agree to perform this
         Agreement in the same manner and to the same extent that the Company
         would have been required to perform if no such succession had taken
         place. Upon any such assignment, all references herein to the Company
         shall be deemed to refer to such assignee.

14.      OPPORTUNITY TO SEEK INDEPENDENT ADVICE

         independent legal advice. The Employee acknowledges that he has read

16.      MISCELLANEOUS.

         (a)      WAIVER. The failure of a party to insist upon strict adherence
                  to any term of this Agreement on any occasion shall not be
                  considered a waiver thereof or deprive that party of the right
                  thereafter to insist upon strict adherence to that term or any
                  other term of this Agreement. The waiver by any party hereto
                  of a breach of any provision of this Agreement shall neither
                  operate nor be construed as a general waiver or as a specific
                  waiver of any subsequent breach by any party, unless otherwise
                  expressly provided in such waiver.

         (b)      SEPARABILITY. Subject to Section 8 hereof, if any term or
                  provision of this Agreement or application thereof to anyone
                  or under any circumstances shall be determined to be invalid,
                  illegal or unenforceable by any court of competent
                  jurisdiction and cannot be modified to be enforceable, such
                  term or provision shall immediately become null and void,
                  leaving the remainder of this Agreement in full force and
                  effect.

         (c)      HEADINGS. Section headings are used herein for convenience of
                  reference only and shall not affect the meaning of any
                  provision of this Agreement.

         (d)      RULES OF CONSTRUCTION. Whenever the context so requires, the
                  use of the singular shall be deemed to include the plural and
                  vice versa.

         (e)      COUNTERPARTS. This Agreement may be executed in any number of
                  counterparts, each of which so executed shall be deemed to be
                  an original, and such counterparts will together constitute
                  but one Agreement.

                                      -15-

         (f)      COOPERATION. Following termination of employment for any
                  reason, Employee agrees that he will cooperate fully with the
                  Company and its counsel with respect to any matter (including,
                  without limitation, litigation or governmental proceedings)
                  with which Employee was involved during his Term of employment
                  with the Company. Employee will be available to perform such
                  services on a reasonable basis to the extent requested by the
                  Company. The Company agrees to cooperate with Employee in
                  scheduling such services to minimize disruption of any new
                  employment relationship which Employee may have commenced.
                  Subject to the foregoing sentence, Employee shall render such
                  cooperation in a timely manner or reasonable notice from the
                  Company, and agrees to travel as reasonably requested by the
                  Company in connection with performing such services. The
                  Company will reimburse Employee reasonable out-of-pocket
                  expenses incurred in connection with providing such services
                  in accordance with the Company's policies as in effect from
                  time to time.

         (g)      RELEASE. Notwithstanding anything herein to the contrary, the
                  Company shall not be required to make any of the payments, or
                  provide any of the benefits, to the Employee pursuant to
                  Section 6 hereof unless and until Employee executes and
                  delivers a release of all claims arising out of Employee's
                  employment or termination through the date of the release, but
                  excluding claims for indemnification from the Company under
                  the Indemnification Agreement attached hereto as Exhibit A,
                  which release shall be in a form satisfactory to the Company
                  in its sole discretion.

         (h)      SURVIVAL. Notwithstanding anything in this Agreement to the
                  contrary, the provisions of Sections 7, 8, 9, 10, 12, 15 and
                  16 shall survive any termination of Employee's employment in
                  accordance with their respective terms.

17.      GUARANTEE.

         Capital hereby guarantees the performance by the Company of the
         Company's obligations under this Agreement; PROVIDED, HOWEVER, that
         this guarantee shall terminate and be of no further force or effect
         upon consummation of the U.S. Reorganization Transaction.

                                      -16-
