Stock issuable upon exercise of this Warrant in any name other than that of
Holder, and in such case the Company shall not be required to issue or deliver
any

                                        7



stock certificate until such tax or other charge has been paid or the Person
designated to receive such shares has agreed in writing to pay such tax or
charge or it has been established to the satisfaction of the Company that no
such tax or other charge is due.

      2.3   CONTINUED VALIDITY.  A holder of shares of Common Stock issued upon
the exercise of this Warrant, in whole or in part (other than a holder who
acquires such shares after the same have been publicly sold pursuant to a
Registration Statement under the Securities Act or sold pursuant to Rule 144
thereunder), shall continue to be entitled with respect to such shares to all
rights to which it would have been entitled as Holder under SECTIONS 9, 10, 13,
14 AND 17 of this Warrant.  The Company will, at the time of each exercise of
this Warrant, in whole or in part, upon the request of the holder of the shares
of Common Stock issued upon such exercise hereof, acknowledge in writing, in
form reasonably satisfactory to such holder, its continuing obligation to afford
to such holder all such rights; PROVIDED, HOWEVER, that if such holder shall
fail to make any such request, such failure shall not affect the continuing
obligation of the Company to afford to such holder all such rights.


3.    TRANSFER, DIVISION AND COMBINATION

      3.1   TRANSFER.  Subject to compliance with SECTIONS 9 AND 14, transfer
of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company referred to in
SECTION 2.1 or the office or agency designated by the Company pursuant to
SECTION 12, together with a written assignment of this Warrant substantially in
the form of EXHIBIT B hereto duly executed by Holder or its agent or attorney
and if such transfer is not to be made pursuant to SECTION 14, funds sufficient
to pay any transfer taxes payable upon the making of such transfer.  Upon such
surrender and, if required, such payment, the Company shall, subject to
SECTION 9, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be canceled.  A
Warrant, if properly assigned in compliance with SECTION 9, may be exercised by
a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued.  If requested by the Company, a new Holder shall acknowledge in
writing, in form reasonably satisfactory to the Company, such Holder's
continuing obligations under SECTIONS 9 AND 14 of this Warrant.

                                        8



      3.2   DIVISION AND COMBINATION.  Subject to SECTION 9, this Warrant may
be divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by Holder or its agent or attorney.  Subject to compliance with
SECTION 3.1 and with SECTION 9, as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

      3.3   EXPENSES.  The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
SECTION 3.

      3.4   MAINTENANCE OF BOOKS.  The Company agrees to maintain, at its
aforesaid office or agency, books for the registration, and the registration of
transfer, of the Warrants.


4.    ADJUSTMENTS

      The number of shares of Common Stock for which this Warrant is
exercisable, or the price at which such shares may be purchased upon exercise of
this Warrant, shall be subject to adjustment from time to time as set forth in
this SECTION 4.  The Company shall give each Holder notice of any event
described below which requires an adjustment pursuant to this SECTION 4 at the
time of such event.

      4.1   PREPAYMENT OF OBLIGATIONS UNDER OVERRIDE AGREEMENT.  The number of
shares of Common Stock for which this Warrant is exercisable immediately after
the occurrence of a Repayment Event shall be adjusted as follows:

- ------------------------------------------------------------------------------
If the Repayment Event occurs       Then the number of shares of Common Stock
during the following period         for which this Warrant is exercisable
                                    immediately prior to such event is reduced
                                    by
- ------------------------------------------------------------------------------
Closing Date through June 30,       100%
1996
- ------------------------------------------------------------------------------
July 1, 1996 through                50%
December 31, 1996
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

      4.2   STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any time the
Company shall:

            (a)  take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend

                                        9



payable in, or other distribution of, Additional Shares of Common Stock;

            (b)  subdivide its outstanding shares of Common Stock into a larger
number of shares of Common Stock, or

            (c)  combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (ii) the Current Warrant Price
shall be adjusted to equal (A) the Current Warrant Price in effect immediately
prior to the occurrence of such event, multiplied by the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to the
adjustment divided by (B) the number of shares for which this Warrant is
exercisable immediately after such adjustment.

      4.3   OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION.  The
following provisions shall be applicable to the making of adjustments pursuant
to this SECTION 4, of the number of shares of Common Stock for which this
Warrant is exercisable:

            (a)  WHEN ADJUSTMENTS TO BE MADE.  The adjustments required by this
SECTION 4 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock for which this Warrant is exercisable that would otherwise be
required may be postponed (except in the case of an adjustment pursuant to
SECTION 4.1 or a subdivision or combination of shares of the Common Stock, as
provided for in SECTION 4.2) up to, but not beyond the date of exercise of this
Warrant (or date of repurchase by the Company under SECTION 14) if such
adjustment either by itself or with other adjustments not previously made adds
or subtracts less than one percent (1%) of the shares of Common Stock for which
this Warrant is exercisable immediately prior to the making of such adjustment.
Any adjustment representing a change of less than such minimum amount (except as
aforesaid) which is postponed shall be carried forward and made as soon as such
adjustment, together with other adjustments required by this SECTION 4 and not
previously made, would result in a minimum adjustment or on the date of exercise
or repurchase.  For the purpose of any adjustment, any specified event shall be
deemed to have occurred at the close of business on the date of its occurrence.

                                       10



            (b) FRACTIONAL INTERESTS.  In computing adjustments under this
SECTION 4, fractional interests in Common Stock shall be taken into account to
the nearest 1/10th of a share.

            (c)  WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend or distribution, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

      4.4   REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then each Holder shall have the right thereafter to receive,
upon exercise of such Holder's Warrant, the number of shares of common stock of
the successor or acquiring corporation and Other Property receivable upon or as
a result of such reorganization, reclassification, merger, consolidation or
disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event.  In case of
any such reorganization, reclassification, merger, consolidation or disposition
of assets, the successor or acquiring corporation shall expressly assume the due
and punctual observance and performance of each and every covenant and condition
of this Warrant to be performed and observed by the Company and all the
obligations and liabilities hereunder, subject to such modifications as may be
deemed appropriate (as determined by resolution of the Board of Directors of the
Company) in order to provide for adjustments of the shares of Common Stock for
which this Warrant is exercisable, which adjustments shall be as nearly
equivalent as practicable to the adjustments provided for in this SECTION 4.
For purposes of this SECTION 4.4, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or rights on liquidation over any other class of stock
of such corporation and which is not subject to redemption and shall also
include any evidences of indebtedness, shares of stock or other securities which
are

                                       11


convertible into or exchangeable for any such stock, either immediately or upon
a specified date or the happening of a specified event and any warrants or other
rights to subscribe for or purchase any such stock.  The foregoing provisions of
this SECTION 4.4 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or dispositions of assets.


5.    NOTICES TO WARRANT HOLDERS

      5.1   NOTICE OF ADJUSTMENTS.  Whenever the number of shares of Common
Stock for which this Warrant is exercisable, or whenever the price at which a
share of such Common Stock may be purchased upon exercise of the Warrants, shall
be adjusted pursuant to SECTION 4, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was calculated, specifying the number of shares of
Common Stock for which this Warrant is exercisable and (if such adjustment was
made pursuant to SECTION 4.4) describing the number and kind of any other shares
of stock or Other Property for which this Warrant is exercisable, and any change
in the purchase price or prices thereof, after giving effect to such adjustment
or change.  The Company shall promptly cause a signed copy of such certificate
to be delivered to each Holder in accordance with SECTION 17.2.  The Company
shall keep at its office or agency designated pursuant to SECTION 12 copies of
all such certificates and cause the same to be available for inspection at said
office during normal business hours by any Holder or any prospective purchaser
of a Warrant designated by a Holder thereof.

      5.2   NOTICE OF CERTAIN CORPORATE ACTION.  The Holder shall be entitled
to the same rights to receive notice of corporate action as any holder of Common
Stock.

6.    NO IMPAIRMENT

      The Company shall not by any action avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms.  Without limiting the
generality of the foregoing, the Company will (a) not increase the par value of
any shares of Common Stock receivable upon the exercise of this Warrant above
the amount payable therefor upon such exercise immediately prior to such
increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock, upon the exercise of this Warrant, and
(c) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory

                                       12



body having jurisdiction thereof as may be necessary to enable the Company to
perform its obligations under this Warrant.

      Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form reasonably
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.


7.    RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
      APPROVAL OF ANY GOVERNMENTAL AUTHORITY; PREFERRED STOCK

      From and after the Closing Date, the Company shall at all times reserve
and keep available for issuance upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.  All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant and payment
therefor in accordance with the terms of such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.

      Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and nonassessable shares of such Common Stock at
such adjusted Current Warrant Price.

      Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

      If any shares of Common Stock required to be reserved for issuance upon
exercise of Warrants require registration or qualification with any governmental
authority under any federal or state law (otherwise than as provided in
SECTION 9) before such shares may be so issued, the Company will in good faith
and as expeditiously as possible and at its expense endeavor to cause such
shares to be duly registered or qualified.


8.    TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

      In the case of all dividends or other distributions by the Company to the
holders of its Common Stock with respect to which any provision of SECTION 4
refers to the taking of a record of such holders, the Company will in each such
case take such a

                                       13



record and will take such record as of the close of business on a Business Day.
The Company will not at any time, except upon dissolution, liquidation or
winding up of the Company, close its stock transfer books or Warrant transfer
books so as to result in preventing or delaying the exercise or transfer of any
Warrant.


9.    RESTRICTIONS ON TRANSFERABILITY

      The Warrants and the Warrant Stock shall not be transferred, hypothecated
or assigned before satisfaction of the conditions specified in this SECTION 9,
which conditions are intended to ensure compliance with the provisions of the
Securities Act and state law, with respect to the Transfer of any Warrant or any
Warrant Stock.  Holder, by acceptance of this Warrant, agrees to be bound by the
provisions of this SECTION 9.

      9.1   RESTRICTIVE LEGEND.

            (a)  Except as otherwise provided in this SECTION 9, each
certificate for Warrant Stock initially issued upon the exercise of this
Warrant, and each certificate for Warrant Stock issued to any subsequent
transferee of any such certificate, shall be stamped or otherwise imprinted with
a legend in substantially the following form:

            "The shares represented by this certificate have not been
      registered under the Securities Act of 1933, as amended, and are
      subject to the conditions specified in a certain Warrant dated as
      of August ___, 1995, originally issued by Morrison Knudsen
      Corporation.  No transfer of the shares represented by this
      certificate shall be valid or effective until such conditions and
      any requirements of federal and state law have been fulfilled.  A
      copy of the form of said Warrant is on file with the Secretary of
      Morrison Knudsen Corporation.  The holder of this certificate, by
      acceptance of this certificate, agrees to be bound by the
      provisions of such Warrant."

            (b)  Except as otherwise provided in this SECTION 9, each Warrant
shall be stamped or otherwise imprinted with a legend in substantially the
following form:

            "This Warrant and the securities represented hereby have not been
      registered under the Securities Act of 1933, as amended, and may not be
      transferred in violation of such Act or state law, the rules and
      regulations thereunder or the provisions of this Warrant."

                                       14



      9.2   NOTICE OF PROPOSED TRANSFERS; REQUESTS FOR REGISTRATION.  Prior to
any Transfer or attempted Transfer of any Warrants or any shares of Restricted
Common Stock, the holder of such Warrants or Restricted Common Stock shall give
10 days prior written notice (a "Transfer Notice") to the Company of such
holder's intention to effect such Transfer, describing the manner and
circumstances of the proposed Transfer, and shall deliver to the Company a
certificate of such holder representing and warranting that the proposed
Transfer of such Warrants or such Restricted Common Stock may be effected
without registration under the Securities Act.  After receipt of the Transfer
Notice and certificate, the Company shall, within five days thereof, so notify
the holder of such Warrants or such Restricted Common Stock and such holder
shall thereupon be entitled to Transfer such Warrants or such Restricted Common
Stock, in accordance with the terms of the Transfer Notice.  Each certificate,
if any, evidencing such shares of Restricted Common Stock issued upon such
Transfer shall bear the restrictive legend set forth in SECTION 9.1(a), and each
Warrant issued upon such Transfer shall bear the restrictive legend set forth in
SECTION 9.1(b).  The holder of the Warrants or the Restricted Common Stock, as
the case may be, giving the Transfer Notice shall not be entitled to transfer
and shall not transfer such Warrants or such Restricted Common Stock until
receipt of notice from the Company under this SECTION 9.2(a).

      The holders of Warrants and Warrant Stock shall have the right to request
registration of such Warrant Stock pursuant to and in accordance with the terms
of the Registration Rights Agreement.

      9.3   TERMINATION OF RESTRICTIONS.  Notwithstanding the foregoing
provisions of SECTION 9, the restrictions imposed by this SECTION 9 upon the
transferability of the Warrants, the Warrant Stock and the Restricted Common
Stock (or Common Stock issuable upon the exercise of the Warrants) and the
legend requirements of SECTION 9.1 shall terminate as to any particular Warrant
or share of Warrant Stock or Restricted Common Stock (or Common Stock issuable
upon the exercise of the Warrants) (i) when and so long as such security shall
have been effectively registered under the Securities Act and disposed of
pursuant thereto or (ii) when the Company shall have received an opinion of
counsel reasonably satisfactory to it that such legend is not required in order
to ensure compliance with the Securities Act.  Whenever the restrictions imposed
by this SECTION 9 shall terminate as to this Warrant, as hereinabove provided,
the Holder hereof shall be entitled to receive from the Company, at the expense
of the Company, a new Warrant bearing the following legend in place of the
restrictive legend set forth hereon:

            "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
      CONTAINED IN SECTION 9 HEREOF TERMINATED ON                , 19   , AND
      ARE OF NO FURTHER FORCE AND EFFECT."

                                       15



All Warrants thereafter issued upon registration of transfer, division or
combination of, or in substitution for, any Warrant or Warrants entitled to bear
such legend shall have a similar legend endorsed thereon.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to any share of
Restricted Common Stock, as hereinabove provided, the holder thereof shall be
entitled to receive from the Company, at the Company's expense, a new
certificate representing such Common Stock not bearing the restrictive legend
set forth in SECTION 9.1(a).

      9.4   LISTING ON SECURITIES EXCHANGE.  So long as the Company shall list
any shares of Common Stock on any securities exchange, it will, at its expense,
list thereon, maintain and, when necessary, increase such listing of, all shares
of Common Stock issued or, to the extent permissible under the applicable
securities exchange rules, issuable upon the exercise of this Warrant, so long
as any shares of Common Stock shall be so listed during the Exercise Period.


10.   SUPPLYING INFORMATION

      The Company shall cooperate with each holder of a Warrant or Restricted
Common Stock in supplying such information as may be reasonably necessary for
such holder to complete and file any information reporting forms presently or
hereafter required by the Commission as a condition to the availability of an
exemption from the Securities Act for the sale of any Warrant or Restricted
Common Stock.


11.   LOSS OR MUTILATION

      Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it, and in
case of mutilation upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder;
PROVIDED, in the case of mutilation, no indemnity shall be required if this
Warrant in identifiable form is surrendered to the Company for cancellation.


12.   OFFICE OF THE COMPANY

      As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency (which may be the principal executive offices of
the Company) where the Warrants may be presented for exercise, registration of
transfer, division or combination as provided in this Warrant.  The Company
shall notify Holder in writing prior to any change of the address of the office
at which the Warrants may be presented.

                                       16



13.   FINANCIAL AND BUSINESS INFORMATION

      13.1  FILINGS.  So long as the Company is a "Public Company" (as
hereinafter defined), the Company will file with the Commission on or before the
due date all regular or periodic reports required to be filed pursuant to the
Exchange Act, and will deliver to the Holder, promptly upon its becoming
available, one copy of each report, notice or proxy statement sent by the
Company to its shareholders generally, and one copy of each regular or periodic
report (including, without limitation, reports on Form 8-K) pursuant to the
Exchange Act or any registration statement, prospectus or written communication
(other than transmittal letters and other communications that are not publicly
available) pursuant to the Securities Act, filed by the Company with (i) the
Commission or (ii) any securities exchange on which shares of the Common Stock
are listed.

            For purposes of this SECTION 13, the term "Public Company" shall
mean a company (i) that is subject to the reporting requirements of
Section 15(d) of the Exchange Act, or (ii) any of whose securities are
registered pursuant to Section 12(b) or 12(g) of the Exchange Act.

      13.2  QUARTERLY INFORMATION.  During any period in which the Company is
not a Public Company, as soon as available and in any event within 45 days after
the end of each of the first three fiscal quarters of each fiscal year of the
Company, the Company will deliver to the Agent a consolidated balance sheet of
the Company and its consolidated Subsidiaries as of the end of such quarter and
the related consolidated statements of income and cash flows for such quarter
and for the portion of the Company's fiscal year ended at the end of such
quarter, setting forth in the case of such income and cash flows in comparative
form the figures for the corresponding quarter and the corresponding portion of
the Company's previous fiscal year, all certified (subject to normal year-end
adjustments) as to fairness of presentation, GAAP, and consistency by the chief
financial officer, controller or treasurer of the Company.

      13.3  ANNUAL INFORMATION.  During any period in which the Company is not
a Public Company, as soon as available and in any event within 90 days after the
end of each fiscal year of the Company, the Company will deliver to the Agent a
consolidated balance sheet of the Company and its consolidated Subsidiaries as
of the end of such fiscal year and the related consolidated statements of
income, retained earnings and cash flows for such fiscal year, setting forth in
each case in comparative form the figures for the previous fiscal year, all
reported on in a manner acceptable to the Commission by Deloitte & Touche or
other independent public accountants of nationally recognized standing, together
with an unaudited annual report prepared on a consolidating basis in conformity
with GAAP.

                                       17



14.   THE COMPANY'S REPURCHASE OF THE WARRANT

      14.1  OPTION TO REPURCHASE WARRANT.  From time to time on or after the
Initial Exercise Date and until the Expiration Date, the Company shall have the
right, upon not less than thirty (30) days prior written notice to any Holder,
to repurchase from such Holder, from any source of funds legally available
therefor, on the date and in the manner set forth in SECTION 14.2, all or any
part of the Warrant then held by such Holder for an amount  determined by
multiplying (x) the number of shares of Common Stock subject to such Warrant or
portion thereof being repurchased, by (y) the difference between (i) 110% of the
higher of the Current Market Price per share of Common Stock and the Current
Warrant Price per share of Common Stock as of the date of such notice, and
(ii) the Current Warrant Price per share of Common Stock as of the date of such
notice; PROVIDED, HOWEVER, that nothing herein shall preclude the exercise by
Holder of any portion of this Warrant exercisable at any time prior to such
repurchase.
      14.2  DETERMINATION AND PAYMENT OF REPURCHASE PRICE.

            (a)  The purchase price for any repurchase pursuant to this
SECTION 14 (the "Repurchase Price") shall be determined within ten (10) days of
the date of the repurchase notice given by the Company pursuant to SECTION 14.1,
and shall be payable in cash from any source of funds legally available therefor
within ten (10) days following the date of such determination of the Repurchase
Price.  On the date of any repurchase of this Warrant pursuant to this
SECTION 14, each Holder shall assign to the Company such Holder's Warrant or
portion thereof being repurchased, without any representations (other than a
representation that such Holder owns such Warrant free and clear of any liens,
pledges or encumbrances), by the surrender of such Holder's Warrant at the
principal office of the Company referred to in SECTION 2.1 against payment
therefor of the Repurchase Price by, at the option of such Holder, and subject
to the immediately following sentence, (i) wire transfer to an account in a bank
located in the United States designated by such Holder for such purpose or
(ii) a certified or official bank check drawn on a member of the New York
Clearing House payable to the order of such Holder.  If less than all of any
Holder's Warrant is being repurchased, the Company shall, pursuant to SECTION 3,
cancel such Warrant and issue in the name of, and deliver to, such Holder a new
Warrant for the portion not being repurchased.

            (b)  Each Holder of Warrants shall have the right at any time to
object to the determination of the Repurchase Price pursuant to this SECTION 14
by specifying in writing to the Company the nature of its objection and, unless
such objection is resolved by agreement of the Company and such Holder, the
Company and such Holder shall each have the right to subject the disputed
determination to separate firms of independent accountants of recognized
national standing for a joint resolution of the

                                       18



objection of such Holder (which firms of independent accountants may, in either
case, be the firms of accountants regularly retained by the Company or such
Holder).  If such firms cannot jointly resolve the objection of such Holder,
then, unless otherwise directed by agreement of the Company and such Holder,
such firms shall in their sole discretion choose another firm of independent
certified public accountants of recognized national standing, which is not the
regular auditor of such Holder or the Company, which firm shall resolve such
objection.  In either case, for purposes hereof the determination so made shall
be conclusive and binding on the Company, such Holder and all Persons claiming
under or through any of them, and any adjustment in the determination of the
Repurchase Price per share of Common Stock resulting from such determination
shall be made.  The cost of any such determination shall be borne by the Company
if it results in an increase of the aggregate Repurchase Price for all shares of
Common Stock issuable upon the exercise hereof and by such Holder if it results
in no adjustment or a decrease of the aggregate Repurchase Price for all shares
of Common Stock issuable upon the exercise hereof.

            (c)  Any repurchase by the Company of all or any portion of the
Warrant pursuant to SECTION 14.1 which is delayed by (1) the failure of the
Company to determine the Repurchase Price within the time periods required in
SECTION 14.3(a) or (2) an objection by any Holder of the Warrant to any such
determination pursuant to SECTION 14.3(b) shall be consummated within ten (10)
days after, as the case may be, the determination of the Repurchase Price or the
resolution of such objection.

            (d)  In the event that the determination of the Repurchase Price
requires an opinion from an investment banking firm or accounting firm, all
costs and fees associated therewith shall, except to the extent otherwise
provided in SECTION 14.3(b) above, be paid by the Company.

      14.3  PRO RATA REPURCHASE OF WARRANTS.  Notwithstanding anything to the
contrary contained in this SECTION 14, any repurchase by the Company of this
Warrant or any portion thereof shall be made pro rata and on the same terms with
respect to all Warrants and all Lender Warrants then outstanding, and any
obligation of Holder pursuant to this SECTION 14 to sell this Warrant or any
portion thereof to the Company is conditioned upon the Company's compliance with
such requirement.


15.   APPRAISAL

      If required under this Warrant, the determination of the Appraised Value
per share of Common Stock shall be made by an investment banking firm of
nationally recognized standing selected by the Company and acceptable to the
Majority Holders.  If the investment banking firm selected by the Company is not
acceptable to the Majority Holders and the Company and the

                                       19



Majority Holders cannot agree on a mutually acceptable investment banking firm,
then the Majority Holders and the Company shall each choose one such investment
banking firm and the respective chosen firms shall agree on another investment
banking firm which shall make the determination.  The Company shall retain, at
its sole cost, such investment banking firms as may be necessary for the
determination of Appraised Value required by the terms of this Warrant.


16.   LIMITATION OF LIABILITY

      No provision hereof (including, without limitation, any of the provisions
under Section 7), in the absence of affirmative action by Holder to purchase
shares of Common Stock, and no enumeration herein of the rights or privileges of
Holder hereof, shall give rise to any liability of such Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such
liability is asserted by the Company, or by creditors of the Company.


17.   MISCELLANEOUS

      17.1  NONWAIVER AND EXPENSES.  No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies.
If the Company fails to make, when due, any payments provided for hereunder, or
fails to comply with any other provision of this Warrant, the Company shall pay
to Holder such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys' fees, including those of
appellate proceedings, incurred by Holder in collecting any amounts due pursuant
hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

      17.3  INDEMNIFICATION.  In addition to the indemnities provided in the
Registration Rights Agreement, the Company agrees to indemnify and hold harmless
Holder, its officers, directors, employees, agents, and attorneys from and
against any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, attorneys' fees, expenses and disbursements of
any kind which may be imposed upon, incurred by or asserted against Holder
relating to or arising out of (i) Holder's exercise of this Warrant and/or
ownership of any shares of Warrant Stock issued in consequence thereof, or
(ii) any litigation to which Holder is made a party in its capacity as a
stockholder or warrant holder of the Company; PROVIDED, HOWEVER, that the
Company will not be liable hereunder to the extent that any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, attorneys' fees, expenses or disbursements are found in a final non-
appealable judgment by a court to have resulted from either (i) Holder's gross
negligence or willful misconduct, (ii) actions or omissions taken or not taken
by Holder in any capacity other

                                       21



than as a stockholder or warrant holder of the Company, or (iii) any violation
of federal or state securities laws by Holder, which is not caused by any action
or inaction of the Company.

      17.4  REMEDIES.  Each holder of Warrants and Warrant Stock, in addition
to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under
SECTIONS 9, 10, 13 AND 14 of this Warrant.  Each party agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of SECTION 9, 10, 13 OR 14 of this Warrant and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

      17.5  SUCCESSORS AND ASSIGNS.  Subject to the provisions of SECTIONS 3.1
AND 9, this Warrant and the rights evidenced hereby shall inure to the benefit
of and be binding upon the successors of the Company and the successors and
assigns of Holder.  The provisions of this Warrant are intended to be for the
benefit of all Holders from time to time of this Warrant, and shall be
enforceable by any such Holder.

      17.6  AMENDMENT.  This Warrant and all other Warrants may be modified or
amended or the provisions hereof waived with the written consent of the Company
and the Majority Holders; PROVIDED, HOWEVER, that no such Warrant may be
modified or amended to reduce the number of shares of Common Stock for which
such Warrant is exercisable (including, without limitation, by way of amendment
of SECTION 4.1), or to increase the price at which such shares may be purchased
upon exercise of such Warrant (before giving effect to any adjustment as
provided therein), or to modify the time period during which such Warrant may be
exercised without the prior written consent of the Holder thereof.

      17.7  SEVERABILITY.  Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
