            QUESTIONS AND ANSWERS ABOUT THE DEBENTURE EXCHANGE OFFER

Q:  WHAT IS THE DEBENTURE EXCHANGE OFFER?

A:  In the debenture exchange offer, Peter Kiewit Sons', Inc. is offering the
    holders of its outstanding convertible debentures the opportunity to
    exchange their Kiewit debentures for:

     - United Metro debentures convertible into shares of United Metro common
       stock; or

     - both shares of United Metro common stock and new reduced principal amount
       Kiewit debentures convertible into shares of Kiewit common stock.

    United Metro is the new name for Kiewit Materials Company, a wholly owned
    subsidiary of Kiewit.

    The debenture exchange offer is being made in connection with a proposal by
    Kiewit to separate its construction business and its materials business into
    two separate, independent companies by distributing shares of United Metro
    common stock to Kiewit stockholders in a spin-off that is intended to be
    tax-free for U.S. federal income tax purposes.

Q:  WHAT IS THE SPIN-OFF?

A:  After the completion of the debenture exchange offer and the share exchange
    described below, Kiewit will distribute the shares of United Metro common
    stock it then holds as a dividend on a pro rata basis to holders of Kiewit
    common stock in the spin-off. Kiewit stockholders will receive in the
    spin-off one share of United Metro common stock for each share of Kiewit
    common stock held.

Q:  WHAT WILL I RECEIVE IF I PARTICIPATE IN THE DEBENTURE EXCHANGE OFFER?

A:  What you will receive if you participate in the debenture exchange offer
    depends on:

     - the series of the Kiewit convertible debentures you currently hold; and

     - the securities you elect to receive in exchange for your Kiewit
       convertible debentures.

    The table below shows what you will receive based on what you hold and which
    option you choose.

       spin-off. Kiewit stockholders will receive in the spin-off one share of
       United Metro common stock for each share of Kiewit common stock they
       hold.

Q.  WHAT SHOULD I EXPECT TO RECEIVE IF I EXCHANGE A $1,000 PRINCIPAL AMOUNT
    KIEWIT CONVERTIBLE DEBENTURE FOR A UNITED METRO CONVERTIBLE DEBENTURE?

A:  We have prepared the following table to illustrate what you would receive if
    you elected to exchange a $1,000 principal amount Kiewit convertible
    debenture in the debenture exchange offer for a United Metro convertible
    debenture. The table assumes a formula price for Kiewit common stock
    immediately prior to the spin-off of $20.28 per share, the estimated formula
    price as of February 17, 2000. The Kiewit formula price will be reduced in
    the event Kiewit pays a cash dividend prior to completion of the debenture
    exchange offer. The table also assumes an initial formula price for United
    Metro common stock of $6.58 per share. The following is an example for
    illustrative purposes only and may not be indicative of what you will
    actually receive if you participate in the debenture exchange offer.

(1) The terms of the debentures require that, on conversion, the holder pay the
    then current formula price for the fraction of the share necessary to round
    the number of shares issuable on conversion up to the nearest whole number
    of shares. Therefore, on conversion, the holders of the Series 1998 and 1999
    Kiewit convertible debentures would receive 80 and 64 shares of Kiewit
    common stock, respectively. Similarly, on conversion, the holders of the
    Series 2000A, 2000B and 2000C United Metro convertible debentures would
    receive 309, 245 and 197 shares of United Metro common stock, respectively.

Q.  WHAT SHOULD I EXPECT TO RECEIVE IF I EXCHANGE A $1,000 PRINCIPAL AMOUNT
    KIEWIT CONVERTIBLE DEBENTURE FOR BOTH A NEW REDUCED PRINCIPAL AMOUNT KIEWIT
    CONVERTIBLE DEBENTURE AND SHARES OF UNITED METRO COMMON STOCK?

A:  We have prepared the following table to illustrate what you would receive if
    you elected to exchange a $1,000 principal amount Kiewit convertible
    debenture in the debenture exchange offer for both a new reduced principal
    amount Kiewit convertible debenture and shares of United Metro common stock.
    The table assumes a formula price for Kiewit common stock immediately prior
    to the spin-off of $20.28 per share, the estimated formula price as of
    February 17, 2000. The Kiewit formula price will be reduced in the event
    Kiewit pays a cash dividend prior to completion of the debenture exchange
    offer. The table also assumes an initial formula price for United Metro
    common stock of $6.58 per share. The following is an

(1) The terms of the debentures require that, on conversion, the holder pay the
    then current formula price for the fraction of the share necessary to round
    the number of shares issuable on conversion up to the nearest whole number
    of shares. Therefore, on conversion, the holders of the Series 1998 and 1999
    Kiewit convertible debentures would receive 80 and 64 shares of Kiewit
    common stock, respectively. Similarly, on conversion, the holders of the
    Series 2000A, 2000B and 2000C United Metro convertible debentures would
    receive 309, 245 and 197 shares of United Metro common stock, respectively.

(2) Assumes that the holder of the outstanding Kiewit convertible debenture has
    paid the then current formula price for the fraction of the share necessary
    to round the number of shares issuable on conversion up to the nearest whole
    number of shares.

Q:  WHY IS KIEWIT CONDUCTING THE DEBENTURE EXCHANGE OFFER?

A:  Each holder of Kiewit convertible debentures is a party to a repurchase
    agreement that requires that the debentures be sold to Kiewit on termination
    of the holder's employment with Kiewit or a subsidiary of Kiewit. Following
    the completion of the spin-off, United Metro employees will no longer be
    employed by Kiewit or a subsidiary of Kiewit and will no longer meet the
    requirements for owning Kiewit debentures. Therefore, they will be required
    to sell any Kiewit debentures they own back to Kiewit. The debenture
    exchange offer allows debentureholders who are United Metro employees the
    opportunity to acquire securities of their company and avoid having to sell
    any Kiewit debentures they then own back to Kiewit immediately following the
    spin-off.

    Kiewit debentures do not contain provisions which would enable
    debentureholders who are Kiewit employees to participate in the distribution
    of shares of United Metro common stock in the spin-off or which would adjust
    the conversion ratio of the outstanding Kiewit debentures to take into
    account the effect of the spin-off. Following the spin-off, the shares of
    Kiewit common stock issuable on conversion of the Kiewit debentures will
    have a lower aggregate formula price since the formula price for Kiewit
    common stock immediately after the spin-off will be reduced by the book
    value of United Metro distributed as a dividend in the spin-off. The
    debenture exchange offer allows debentureholders who are Kiewit employees
    the opportunity to participate in the spin-off by receiving United Metro
    common stock and new reduced principal amount Kiewit debentures.

Q:  WHAT IS THE SHARE EXCHANGE?

A:  Kiewit is also offering Kiewit stockholders who are United Metro employees
    the opportunity to exchange their shares of Kiewit common stock for shares
    of United Metro common stock with an equal aggregate formula price. Kiewit's
    restated certificate of incorporation generally restricts ownership of
    Kiewit common stock to directors and employees of Kiewit and its
    subsidiaries. Following the completion of the spin-off, United Metro
    employees will no longer be employed by Kiewit or a subsidiary of Kiewit and
    will

                                        4
<PAGE>   13
     no longer meet the requirements for owning Kiewit common stock. Therefore,
     they will be required to sell any Kiewit common stock they then own back to
     Kiewit. To provide United Metro employees with a larger, more direct stake
     in the materials business and an alternative to selling their Kiewit common
     stock back to Kiewit for cash immediately following the spin-off, Kiewit is
     offering Kiewit stockholders who are United Metro employees the opportunity
     to exchange their shares of Kiewit common stock for shares of United Metro
     common stock with an equal aggregate formula price.

Q:  WHY HAS KIEWIT DECIDED TO SEPARATE UNITED METRO FROM KIEWIT?

A:  The board of directors and management of Kiewit have concluded that
    separation of its materials business and its construction business by means
    of a spin-off is in the best interests of Kiewit and Kiewit's stockholders.
    In reaching this conclusion, Kiewit's board of directors and management
    considered that, as a result of the spin-off, the debenture exchange offer
    and the share exchange:

    - the senior management of United Metro will acquire a larger, direct
      interest in the materials business that reflects solely the performance of
      United Metro;

    - United Metro employees will acquire a larger, direct interest in the
      materials business, which the Kiewit board of directors believes is
      essential to United Metro's ability to better retain, attract, and
      motivate its employees; and

    - United Metro should improve its ability to make sales to, and secure
      contracts from, unrelated construction businesses that have concerns about
      doing business with United Metro while it is owned and controlled by a
      direct competitor.

Q:  HOW DO I DECIDE WHETHER TO PARTICIPATE IN THE DEBENTURE EXCHANGE OFFER?

A:  Whether you should participate in the debenture exchange offer and which
    option you should choose if you decide to participate in the offer depends
    on a number of factors, including whether you are a United Metro employee or
    a Kiewit employee. The table below shows what you will receive and the
    consequences of each choice you may make in the debenture exchange offer.

    You should consider all of the factors described under "Risk Factors"
    starting at page 16. Neither Kiewit, United Metro nor any of their
    respective directors make any recommendation as to whether you should tender
    your Kiewit debentures. You must make your own decision as to whether to
    tender your Kiewit debentures after reading this document and consulting
    with your advisors based on your own financial position and requirements.

Q:  TO WHOM WILL I BE ABLE TO TRANSFER NEW REDUCED PRINCIPAL AMOUNT KIEWIT
    CONVERTIBLE DEBENTURES?

A:  The new reduced principal amount Kiewit debentures will be subject to
    substantial transfer restrictions and will remain subject to the repurchase
    agreement executed by the debentureholders at the time of initial purchase
    of the outstanding Kiewit debentures. Specifically, the terms of the
    repurchase agreement prohibit Kiewit debentureholders from transferring the
    Kiewit debentures in any manner except in a sale to Kiewit. The repurchase
    agreement also requires the holder to sell the Kiewit debentures back to
    Kiewit upon the termination of the holder's employment with Kiewit.

Q:  TO WHOM WILL I BE ABLE TO TRANSFER UNITED METRO CONVERTIBLE DEBENTURES?

A:  The United Metro debentures will be subject to substantial transfer
    restrictions. Each holder of Kiewit debentures who elects to receive United
    Metro debentures will be required to execute a repurchase agreement with
    United Metro. Specifically, the terms of the repurchase agreement will
    prohibit United Metro debentureholders from transferring the United Metro
    debentures in any manner except in a sale to United Metro. The repurchase
    agreement will also require the holder to sell the United Metro debentures
    back to United Metro if the holder voluntarily terminates his or her
    employment with United Metro or United Metro terminates his or her
    employment for cause.

Q:  WHAT WILL I RECEIVE IF I CONVERT THE NEW REDUCED PRINCIPAL AMOUNT KIEWIT
    DEBENTURES?

A:  The new reduced principal amount Kiewit debentures will be convertible
    during the applicable conversion period into the same number of shares of
    Kiewit common stock as the outstanding Kiewit debentures.

                                        6
<PAGE>   15

Q:  WHAT WILL I RECEIVE IF I CONVERT THE UNITED METRO DEBENTURES?

A:  The United Metro debentures will be convertible during the applicable
    conversion period into shares of United Metro common stock with an initial
    aggregate formula price equal to the aggregate formula price of the Kiewit
    common stock into which the holder's Kiewit debenture was convertible.

    The United Metro debentures will also be convertible during the one-month
    period after the occurrence of any of the following:

     - the holder's death;

     - a change of control of United Metro; or

     - a call for redemption of the holder's debentures.

Q:  WHAT IS "FORMULA PRICE"?

A:  The formula price of Kiewit common stock is the per share price at which
    Kiewit buys and sells shares of its common stock and is based on the
    adjusted book value of Kiewit at the end of the previous year less the
    amount of declared dividends during the current year. The estimated formula
    price of Kiewit common stock on February 17, 2000 was $20.28 per share. The
    Kiewit formula price will be reduced in the event Kiewit pays a cash
    dividend prior to the completion of the debenture exchange offer.

    The formula price of United Metro common stock is the per share price at
    which United Metro will buy shares of its common stock and is based on the
    adjusted book value of United Metro at the end of the previous year less the
    amount of declared dividends during the current year. In addition to any
    adjustments for declared dividends during the current year, the initial
    formula price for United Metro common stock is also adjusted for the amount
    of any capital contributions made by Kiewit to United Metro during fiscal
    year 2000 prior to the spin-off.

Q:  CAN I PARTICIPATE WITH ONLY A PORTION OF MY KIEWIT CONVERTIBLE DEBENTURES IN
    THE DEBENTURE EXCHANGE OFFER?

A:  Yes. You can tender some or all of your Kiewit debentures so long as the
    tendered debentures are in denominations of $1,000 or an integral multiple
    of $1,000. However, following the spin-off, if you are a United Metro
    employee, you will be required to sell any Kiewit debentures you then hold
    back to Kiewit. If you are a Kiewit employee, the shares of Kiewit common
    stock issuable on conversion of the Kiewit debentures will have a lower
    aggregate formula price since the formula price for Kiewit common stock
    immediately after the spin-off will be reduced by the book value of United
    Metro distributed as a dividend in the spin-off.

Q:  DO I HAVE TO DO ANYTHING IF I WANT TO RETAIN MY KIEWIT DEBENTURES?

A:  No, you do not have to do anything if you want to retain your Kiewit
    debentures. However, following the spin-off, if you are a United Metro
    employee, you will be required to sell any Kiewit debentures you then hold
    back to Kiewit. If you are a Kiewit employee, the shares of Kiewit common
    stock issuable on conversion of the Kiewit debentures will have a lower
    aggregate formula price since the formula price for Kiewit common stock
    immediately after the spin-off will be reduced by the book value of United
    Metro distributed as a dividend in the spin-off.

Q:  HOW DO I PARTICIPATE IN THE DEBENTURE EXCHANGE OFFER?

A:  Complete and sign the letter of transmittal designating the principal amount
    of Kiewit debentures you wish to tender. Send it, together with your
    convertible debentures and any other documents required by the letter of
    transmittal, by registered mail, return receipt requested, so that it is
    received by Kiewit at the address on the back cover of this offering
    circular-prospectus before the expiration of the debenture exchange offer.
    If you are exchanging your outstanding Kiewit debentures for United Metro
    debentures, you must also send an executed United Metro repurchase agreement
    to Kiewit.

                                        7
<PAGE>   16

    If your Kiewit debenture has been pledged to a lender, you must make
    arrangements with the lender for the valid tender of the pledged Kiewit
    debentures. If, however, the lender is Enterprise Bank, N.A. or U.S. Bank,
    N.A., Kiewit will arrange directly with the bank for delivery of the pledged
    debentures to Kiewit.

Q:  CAN I CHANGE MY MIND AFTER I TENDER MY KIEWIT DEBENTURES?

A:  Yes. You may withdraw tenders of your debentures any time before the
    expiration of the debenture exchange offer. If you change your mind again,
    you can retender your Kiewit debentures by following the tender procedures
    again prior to the expiration of the debenture exchange offer. However,
    following the spin-off, if you are a United Metro employee, you will be
    required to sell any Kiewit debentures you then hold back to Kiewit. If you
    are a Kiewit employee, the shares of Kiewit common stock issuable on
    conversion of the Kiewit debentures will have a lower aggregate formula
    price since the formula price for Kiewit common stock immediately after the
    spin-off will be reduced by the book value of United Metro distributed as a
    dividend in the spin-off.

Q:  ARE THERE ANY CONDITIONS TO KIEWIT'S OBLIGATION TO COMPLETE THE DEBENTURE
    EXCHANGE OFFER?

A:  Yes. Kiewit has received a ruling from the IRS confirming that the debenture
    exchange offer, the share exchange and the spin-off generally will be
    tax-free transactions for U.S. federal income tax purposes. The debenture
    exchange offer will not be completed unless that ruling remains in effect.

    Kiewit reserves the right to abandon the spin-off at any time prior to the
    completion of the debenture exchange offer and the share exchange. If Kiewit
    abandons the spin-off, it will not complete the debenture exchange offer or
    the share exchange. Kiewit also reserves the right to abandon the debenture
    exchange offer or the share exchange at any time prior to its completion. If
    Kiewit abandons either the debenture exchange offer or the share exchange,
    it will not complete the spin-off or the other exchange.

    There is no requirement that any minimum principal amount of debentures are
    tendered for the debenture exchange offer to be completed.

Q:  WHEN DOES THE DEBENTURE EXCHANGE OFFER EXPIRE?

A:  The debenture exchange offer and withdrawal rights will expire at 11:59
    p.m., Omaha time, on             , 2000, unless extended. You must tender
    your Kiewit debentures prior to the expiration date if you wish to
    participate in the debenture exchange offer.

Q:  WILL UNITED METRO COMMON STOCK BE LISTED ON AN EXCHANGE?

A:  The United Metro common stock will not be listed on any national securities
    exchange or quoted on the Nasdaq National Market.

Q:  ARE SHARES OF UNITED METRO COMMON STOCK TRANSFERABLE?

A:  The United Metro common stock will be subject to substantial transfer
    restrictions. Specifically, holders of United Metro common stock will be
    prohibited from transferring the United Metro common stock in any manner
    except in a sale to United Metro or in a transfer for estate planning
    purposes that meets specified requirements. Upon the death of a United Metro
    stockholder, the shares of United Metro common stock owned by the deceased
    stockholder will be permitted to be transferred to his or her estate,
    provided that the shares transferred to the transferee will be subject to
    the same transfer restrictions. However, unlike Kiewit common stock, United
    Metro stockholders will not be required to sell their United Metro common
    stock back to United Metro upon their retirement or other termination of
    their employment with United Metro or Kiewit, as the case may be. All
    transfer restrictions may be terminated by the United Metro board at any
    time.

    Holders of United Metro common stock are permitted to pledge their common
    stock for loans in connection with the ownership of their common stock.

<PAGE>   17

Q:  HOW CAN I SELL SHARES OF UNITED METRO COMMON STOCK TO UNITED METRO?

A:  At any time on or prior to the 15th day of any calendar month, United Metro
    stockholders may offer to sell all or part of their United Metro common
    stock to United Metro at the current formula price. United Metro will
    generally be required to accept the offer within 10 days of receipt of the
    offer.

    United Metro's repurchase obligations may be terminated by United Metro's
    board of directors at any time. However, the board shall not have that
    authority unless it has also determined that the United Metro common stock
    is publicly traded.

Q:  WILL I BE TAXED ON THE DEBENTURES AND/OR THE SHARES OF UNITED METRO COMMON
    STOCK THAT I RECEIVE IN THE DEBENTURE EXCHANGE OFFER?

A:  You will generally not recognize gain or loss for U.S. federal income tax
    purposes upon the receipt of debentures and/or shares of United Metro common
    stock in the debenture exchange offer, except to the extent that you are
    required to sell any debentures so received back to Kiewit or United Metro
    immediately following the spin-off.

Q:  IN THE EVENT I CHOOSE TO RECEIVE NEW REDUCED PRINCIPAL AMOUNT KIEWIT
    DEBENTURES AND SHARES OF UNITED METRO COMMON STOCK IN THE DEBENTURE EXCHANGE
    OFFER, WHAT WILL BE THE TAX BASIS AND HOLDING PERIOD OF THE DEBENTURES AND
    THE SHARES FOR U.S. FEDERAL INCOME TAX PURPOSES?

                                 Holders of Kiewit convertible debentures who
                                 exchange their Kiewit debentures for United
                                 Metro debentures will receive United Metro
                                 debentures in the same principal amount,
                                 bearing interest at the same rate as the Kiewit
                                 convertible debentures for which they were
                                 exchanged and due on October 31, 2010. The
                                 United Metro debentures will be convertible
                                 into shares of United Metro common stock with
                                 an initial aggregate formula price equal to the

                                 stock into which the holder's Kiewit debentures
                                 were convertible at the expiration of the

<PAGE>   20

                                 the same period that the Kiewit debentures were
                                 convertible into shares of Kiewit common stock.
                                 The United Metro debentures will also be
                                 convertible in other limited circumstances.

                                 Holders of Kiewit convertible debentures who
                                 exchange their debentures for United Metro

                                 Kiewit convertible debentures will receive:

                                 - new reduced principal amount Kiewit
                                   debentures, bearing interest at the same rate
                                   as the Kiewit convertible debentures for
                                   which they were exchanged and due on October
                                   31, 2010; and

                                 - shares of United Metro common stock.

                                 The new Kiewit debentures will be convertible
                                 into the same number of shares of Kiewit common
                                 stock as the original Kiewit debenture during
                                 the same period that the original Kiewit
                                 debenture was convertible. The principal amount
                                 of the new Kiewit debenture will be the
                                 principal amount of the holder's original
                                 Kiewit debenture less the initial formula price
                                 of the United Metro common stock received by
                                 the holder in the debenture exchange offer. The
                                 number of shares of United Metro common stock
                                 the holder of a new reduced principal amount
                                 Kiewit debenture will receive will be equal to
                                 the number of shares that holder would have
                                 received had he or she converted his or her
                                 original Kiewit debenture prior to the spin-off
                                 and received the dividend of United Metro
                                 common stock in the spin-off.

                                 All Kiewit convertible debentures properly
                                 tendered and not withdrawn will be exchanged on
                                 the terms and conditions of the debenture
                                 exchange offer. Kiewit will promptly return to
                                 debentureholders any Kiewit debentures not
                                 accepted for exchange following the expiration
                                 of the debenture exchange offer.

TRANSFER RESTRICTIONS.........   The new reduced principal amount Kiewit

                                 to the repurchase agreement executed by the
                                 debentureholders at the time of the initial
                                 purchase of the Kiewit debentures.
                                 Specifically, the terms of the repurchase

                                 holder voluntarily terminates his or her
                                 employment with United Metro or United Metro

                                 and the spin-off generally will be tax-free

                                 pledged Kiewit debentures. If, however, the
                                 lender is Enterprise Bank, N.A. or U.S. Bank,
                                 N.A., Kiewit will arrange directly with the
                                 bank for delivery of the pledged Kiewit
                                 debentures to Kiewit.

  KIEWIT CONVERTIBLE
  DEBENTURES..................   Kiewit will deliver United Metro convertible
                                 debentures, new reduced principal amount Kiewit
                                 convertible debentures and certificates

                                 of Kiewit convertible debentures for exchange.

MATERIAL U.S. FEDERAL INCOME
TAX CONSEQUENCES..............   Debentureholders will generally not recognize
                                 gain or loss for U.S. federal income tax
                                 purposes as a result of the debenture exchange
                                 offer, except to the extent that the debentures
                                 received are immediately repurchased following
                                 the spin-off. A debentureholder will generally
                                 have a tax basis in the common stock and/or
                                 debentures received equal to the tax basis in
                                 the Kiewit debentures exchanged, allocated, in
                                 the case of the receipt of United Metro common
                                 stock and new reduced principal amount Kiewit
                                 debentures, in proportion to the fair market
                                 values of each at the time of the exchange. A
                                 debentureholder's holding period for the
                                 debentures and/or common stock received will
                                 include the holding period for the Kiewit
                                 debentures exchanged, provided such debentures
                                 were held as capital assets at the time of the
                                 exchange. See "Material U.S. Federal Income Tax
                                 Consequences" on page 86.

MATERIAL CANADIAN FEDERAL
INCOME TAX CONSEQUENCES.......   As a result of the debenture exchange offer,
                                 Canadian resident debentureholders will realize
                                 a gain or loss for Canadian tax purposes
                                 relating to the U.S. dollar principal amount of
                                 the outstanding Kiewit debentures. In addition,
                                 debentureholders may receive a taxable stock
                                 option benefit from Canadian employment,
                                 depending on whether a value test is satisfied.

USE OF PROCEEDS...............   Neither Kiewit nor United Metro will receive
                                 any proceeds from the issuance of debentures or
                                 United Metro common stock in the debenture
                                 exchange offer.

RISK FACTORS..................   You should consider carefully the matters
                                 described under the caption "Risk Factors," as
                                 well as the other information set forth in this
                                 offering circular-prospectus.

DETERMINING WHETHER TO
PARTICIPATE IN THE DEBENTURE
  EXCHANGE OFFER..............   You should consider all of the factors
                                 described under "Risk Factors" starting at page
                                 16. Neither Kiewit, United Metro nor any of
                                 their respective directors make any
                                 recommendation as to whether you should tender
                                 your Kiewit debentures. You must make your own
                                 decision as to whether to tender your Kiewit
                                 debentures after reading this document and
                                 consulting with your advisors based on your own
                                 financial position and requirements.

EFFECTS OF THE DEBENTURE
  EXCHANGE OFFER..............   Kiewit debentureholders will be affected by the
                                 spin-off regardless of whether they choose to
                                 participate in the debenture exchange offer.

CONSEQUENCES OF A DECISION NOT
TO EXCHANGE...................   United Metro Employees

                                 Kiewit debentureholders who are United Metro
                                 employees will cease to be employees of Kiewit
                                 or a subsidiary of Kiewit after the spin-off.
                                 Consequently, they will no longer meet the
                                 requirements for owning Kiewit debentures and
                                 will be required to sell any Kiewit debentures
                                 they then own back to Kiewit.

                                 Kiewit Employees

                                 For those Kiewit debentureholders who are
                                 Kiewit employees, the shares of Kiewit common
                                 stock issuable on conversion of the Kiewit
                                 debentures will have a lower aggregate formula
                                 price following the spin-off, since that
                                 formula price will be reduced by the book value
                                 of United Metro distributed as a dividend in
                                 the spin-off.

CONSEQUENCES OF A DECISION TO
  EXCHANGE....................   United Metro Employees

                                 Kiewit debentureholders who are United Metro
                                 employees and who exchange some or all of their
                                 Kiewit convertible debentures in the debenture
                                 exchange offer will receive at their option:

                                 - United Metro debentures convertible into
                                   shares of United Metro common stock in a
                                   transaction that is intended to be tax-free
                                   to debentureholders for U.S. federal income
                                   tax purposes; or

                                 - both new reduced principal amount Kiewit
                                   debentures convertible into shares of Kiewit
                                   common stock, and shares of United Metro
                                   common stock.

                                 A United Metro employee who elects to receive
                                 new reduced principal amount Kiewit debentures
                                 and United Metro common stock will be required
                                 to sell the new Kiewit debentures back to
                                 Kiewit following the spin-off.

                                 Kiewit Employees

                                 Kiewit debentureholders who are Kiewit
                                 employees and who exchange some or all of their
                                 Kiewit convertible debentures in the debenture
                                 exchange offer will receive at their option:

                                 - United Metro debentures convertible into
                                   shares of United Metro common stock; or

                                 - both new reduced principal amount Kiewit
                                   debentures convertible into shares of Kiewit
                                   common stock, and shares of United Metro
                                   common stock in a transaction that is
                                   intended to be tax-free to debentureholders
                                   for U.S. federal income tax purposes.

                                 A Kiewit employee who elects to receive United
                                 Metro debentures will be required to sell those
                                 debentures back to United Metro following the
                                 spin-off.

                                  RISK FACTORS

     In considering whether to participate in the debenture exchange offer, you
should consider carefully all of the information set forth or incorporated in
this offering circular-prospectus and, in particular, the following risk
factors. In addition, for a discussion of additional uncertainties associated
with forward-looking statements in this offering circular-prospectus, please see
"Forward-Looking Statements May Prove Inaccurate" on page 21.

RISK FACTORS RELATING TO THE DEBENTURE EXCHANGE OFFER, THE SHARE EXCHANGE AND
THE SPIN-OFF

CONSEQUENCES OF A DECISION NOT TO EXCHANGE

     If the spin-off occurs, those Kiewit debentureholders who are United Metro
employees will cease to be employees of Kiewit or a subsidiary of Kiewit after
the spin-off. Consequently, they will no longer meet the requirements for owning
Kiewit debentures and will be required to sell any Kiewit debentures they then
own back to Kiewit. For those Kiewit debentureholders who are Kiewit employees,
the shares of Kiewit common stock issuable on conversion of the Kiewit
debentures will have a lower aggregate formula price following the spin-off,
since that formula price will be reduced by the book value of United Metro
distributed as a dividend in the spin-off.

POSSIBLE EFFECTS OF THE DEBENTURE EXCHANGE OFFER ON LOANS SECURED BY KIEWIT
DEBENTURES

     In the debenture exchange offer, Kiewit debentureholders may elect to
exchange their Kiewit debentures for either United Metro debentures or both new
reduced principal amount Kiewit debentures and shares of United Metro common
stock. Those debentureholders who choose to receive both new reduced principal
Kiewit debentures and United Metro common stock will receive Kiewit debentures
with a principal amount which is less than the principal amount of the Kiewit
debenture tendered. Consequently, the interest payable with respect to the new
reduced principal amount Kiewit debenture will be less than that payable with
respect to the Kiewit debenture tendered in the debenture exchange offer. To the
extent that a Kiewit debentureholder has obtained financing to purchase his or
her Kiewit debenture, the debentureholder will have less interest income with
which to make payments on that financing.

     If the Kiewit debentures being tendered in the debenture exchange offer are
pledged to a lender, the securities received in exchange will also be subject to
the pledge under the terms of the loan documentation between the debentureholder
and the lender. As a result, the debentureholder may be required to deliver
those securities to his or her lender.

     Debentureholders who have pledged their Kiewit debentures to a lender and
who are considering participation in the debenture exchange offer should consult
with their lender as to the effect of the debenture exchange offer on their
individual loan arrangements.

THE DEBENTURE EXCHANGE OFFER, THE SHARE EXCHANGE AND THE SPIN-OFF WILL RESULT IN
A LOWER FORMULA PRICE FOR KIEWIT COMMON STOCK

     After the completion of the debenture exchange offer, the share exchange
and the spin-off, Kiewit will no longer own any of the outstanding common stock
of United Metro. The formula price for Kiewit common stock is determined by
reducing the prior year's adjusted book value by the amount of the dividends
declared during the current year. The spin-off will be effected by a dividend of
shares of United Metro common stock. Consequently, the formula price for Kiewit
common stock immediately after the spin-off will be reduced by the book value of
United Metro distributed as a dividend in the spin-off, in respect of each
Kiewit share.

RISK FACTORS REGARDING UNITED METRO

A DECREASE IN GOVERNMENT FUNDING OF HIGHWAY CONSTRUCTION AND MAINTENANCE AND
OTHER INFRASTRUCTURE PROJECTS MAY REDUCE UNITED METRO'S SALES AND PROFITS

     A decrease or delay in government funding of highway construction and
maintenance and other infrastructure projects could reduce United Metro's sales
and profits. This is because many of the customers
                                       16
<PAGE>   25

United Metro serves and intends to serve in the future depend substantially on
government funding of highway construction and maintenance and other
infrastructure projects. Unlike some of its competitors, United Metro operates
in a limited number of states. As a result, United Metro may be more vulnerable
than its more geographically diverse competitors to decreases in state
government highway spending in the states in which it operates.

BAD WEATHER IN UNITED METRO'S PEAK SEASON MAY RESULT IN LOWER SALES

     Poor weather during the months of April through November could result in
lower sales of materials, which could reduce United Metro's net sales and
profits. This is because sales of materials are highest during this period and
poor weather conditions may reduce or delay highway construction and maintenance
and other infrastructure projects. In the past, significant changes in weather
conditions during this period have caused variations in demand for materials. In
addition, because United Metro is not as geographically diverse as some of its
competitors, it may be more vulnerable than these competitors to poor weather
conditions in the regions in which it operates.

GENERAL AND LOCAL ECONOMIC DOWNTURNS MAY RESULT IN DECREASED SALES AND PROFITS

     General economic downturns or localized downturns in regions where United
Metro has operations, including any downturns in the construction industry,
could result in a decrease in sales and profits. A majority of United Metro's
sales are to customers in industries and businesses that are cyclical in nature
and subject to changes in general economic conditions, such as the construction
industry. United Metro's business is principally located in the Pacific
Northwest and the Southwest and is dependent upon the economies of those
regions. Because its business is more geographically concentrated than some of
its competitors, it may be more vulnerable to local economic conditions.

AN INCREASE IN THE PRICE OR DECREASE IN THE AVAILABILITY OF OIL MAY INCREASE THE
PRICE OF ASPHALT, RESULTING IN LESS ASPHALT USE BY UNITED METRO'S CUSTOMERS

     A material rise in the price or a material decrease in the availability of
oil could adversely affect United Metro's operating results. Federal, state and
municipal government spending on roads is subject to appropriations by the
particular government entity. Asphalt prices are positively correlated to the
price of oil. Therefore, if there is a material rise in the price or a material
decrease in the availability of oil, there will be a resulting increase in the
cost of producing asphalt, which United Metro would likely attempt to pass along
to its customers. As a result of any price increase, United Metro's customers
may use less asphalt, which would decrease its asphalt sales volumes. A material
increase in the price or decrease in the availability of oil could also lead to
higher gasoline costs which would also increase United Metro's operating costs.
An increase in United Metro's operating costs could adversely affect its
operating results if it cannot pass these increased costs through to its
customers.

UNITED METRO'S SUCCESS DEPENDS SIGNIFICANTLY ON A LIMITED NUMBER OF KEY
PERSONNEL

     United Metro will be managed by a small number of executive officers,
including Christopher J. Murphy, its Chief Executive Officer and President. The
loss of any of its key personnel could have a material adverse effect on United
Metro. United Metro believes that its future success will depend in large part
on its ability to retain and attract highly skilled, knowledgeable,
sophisticated and qualified personnel.

UNITED METRO MAY INCUR SIGNIFICANT DEBT IN THE FUTURE WHICH COULD LIMIT ITS
GROWTH AND ITS ABILITY TO RESPOND TO CHANGING CONDITIONS

     United Metro may incur debt to fund acquisitions it may make as part of its
growth strategy. The extent to which United Metro incurs debt, and the resulting
restrictive and financial covenants that United Metro

                                       17
<PAGE>   26

may be subject to, will have important consequences to the United Metro
stockholders. These include the following:

     - United Metro's ability to use operating cash flows in other areas of its
       business might be limited because it would have to dedicate a substantial
       portion of these funds to pay interest;

     - United Metro might be unable to obtain additional financing to fund its
       growth strategy, working capital, capital expenditures, debt service
       requirements or other purposes;

     - United Metro's ability to adjust to changing market conditions and its
       ability to withstand competition might be hampered by the amount of debt
       it owes; and

     - United Metro might be more vulnerable in a market downturn or a recession
       than its competitors with less debt.

     Future credit agreements that United Metro may enter into may impose
limitations on its ability to repurchase its shares of common stock.

ACQUISITIONS, WHICH ARE A PART OF UNITED METRO'S GROWTH STRATEGY, INVOLVE RISKS
THAT COULD CAUSE ITS ACTUAL GROWTH OR OPERATING RESULTS TO DIFFER FROM ITS
EXPECTATIONS

     United Metro currently intends to grow in part through the acquisition of
additional materials businesses in exchange for cash or debt securities. If it
is not successful in integrating acquired businesses, United Metro may have
difficulty operating its business. United Metro may have greater difficulty
integrating acquired businesses and assets than its competitors because of its
size and its rapid growth. United Metro has completed nine business and asset
acquisitions since 1992. Its future success may be limited because of unforeseen
expenses, difficulties, complications, delays and other risks inherent in the
integration of acquired businesses, including the following:

     - United Metro may not be able to compete successfully for available
       acquisition candidates, complete future acquisitions, or accurately
       estimate the financial effect of any businesses it acquires;

     - Future acquisitions may require United Metro to spend significant amounts
       of cash;

     - United Metro may have trouble integrating acquired businesses and
       retaining personnel;

     - United Metro may ultimately fail to consummate an acquisition, even if it
       announces that it plans to acquire a company;

     - United Metro may choose to acquire a company that is less profitable than
       it is or has lower profit margins than it does;

     - United Metro may not be able to obtain the necessary financing, on
       favorable terms or at all, to finance one or more of its potential
       acquisitions;

     - Acquisitions may disrupt United Metro's business and distract its
       management from other responsibilities;

     - To the extent that any of the companies which United Metro acquires
       fails, the growth of its business could be harmed; and

     - Future acquired companies may have unknown liabilities that could require
       United Metro to spend significant amounts of additional capital.

UNITED METRO MAY BE UNABLE TO COMPETE SUCCESSFULLY IN THE HIGHLY COMPETITIVE
MATERIALS INDUSTRY

     The following factors specific to the construction materials industry may
affect United Metro's business:

     - Transporting materials over even relatively short distances is costly in
       relation to the value of the delivered materials. Therefore, if United
       Metro cannot maintain production sites close to its customers, its
       operating results may be adversely affected;

                                       18
<PAGE>   27

     - The cost and time involved in locating suitable mineral sources,
       obtaining proper permits and establishing operations can be significant
       and if United Metro does not continue to be successful in these matters,
       it may lose growth opportunities and its operating results may be
       adversely affected;

     - United Metro has significant investments in fixed locations in specific
       geographic areas. In the event one or more of its materials production
       sites loses business in its market, it could have a material adverse
       effect on its business, financial condition and results of operations;

     - It is possible that United Metro could encounter increased competition
       from existing competitors or new market entrants that may be
       significantly larger and have greater financial and marketing resources;
       and

     - To the extent United Metro's existing or future competitors seek to gain
       or retain market share by reducing prices, United Metro may be required
       to lower its prices and rates, which would adversely affect its operating
       results.

UNITED METRO MAY BE ADVERSELY AFFECTED BY GOVERNMENT REGULATIONS

     United Metro's operations are subject to and affected by federal, state and
local laws and regulations including such matters as land usage, street and
highway usage, noise levels and health, safety and environmental matters. In
many instances, United Metro must have various permits. United Metro cannot
assure you that it will not incur material costs or liabilities in connection
with regulatory requirements. Its operations may from time to time involve the
use of substances that are classified as toxic or hazardous substances within
the meaning of these laws and regulations. Despite its compliance efforts, risk
of environmental liability is inherent in the operation of United Metro's
business. As a result, environmental liabilities could have a material adverse
effect on United Metro in the future. In addition, future events, such as
changes in existing laws or regulations or enforcement policies, or further
investigation or evaluation of the potential health hazards of United Metro's
products or business activities, may give rise to additional compliance and
other costs that could have a material adverse effect on its business, financial
condition and results of operations. See "Business -- Governmental and
Environmental Regulation" for a further discussion of the effects of regulation
on United Metro's business.

UNITED METRO'S OPERATIONS ARE SUBJECT TO RISKS THAT MAY RESULT IN CLAIMS OF
PERSONAL INJURY, PROPERTY DAMAGE OR OTHER LIABILITIES

     The drivers of United Metro's heavy delivery trucks are subject to traffic
and other hazards associated with providing services on construction sites.
United Metro's plant personnel are subject to the hazards associated with moving
and storing large quantities of heavy raw materials. These operating hazards can
cause personal injury and death, damage to or destruction of property and
environmental damage. United Metro's insurance coverage may not be adequate to
cover all losses or liabilities it may incur in its operations, and United Metro
may not be able to maintain insurance of the types or at levels it deems
necessary or adequate or at rates it considers reasonable. United Metro's
failure to maintain adequate insurance could have a material adverse effect on
its business, financial position, results of operations and cash flows.

UNITED METRO HAS NO OPERATING HISTORY AS AN INDEPENDENT COMPANY

     United Metro does not have an operating history as an independent company
and has historically relied on Kiewit for various financial, administrative and
managerial expertise relevant to operating as an independent company. After the
spin-off, United Metro will be responsible for obtaining or providing its own
administrative functions. While United Metro has been profitable as part of
Kiewit, it cannot be certain that, as a stand-alone company, its future profits
will be comparable to reported historical consolidated results before the
spin-off. In addition, United Metro's credit rating may be lower than that of
Kiewit.

THERE ARE LIMITATIONS ON CHANGES IN CONTROL OF UNITED METRO

     United Metro's restated certificate of incorporation and by-laws contain
provisions that could make it more difficult or even prevent a third party from
acquiring United Metro without the approval of its incumbent board of directors.
These provisions, among other things:

     - divide the board of directors into three classes, with members of each
       class to be elected in staggered three-year terms;

     - prohibit stockholder action by written consent in place of a meeting;

     - limit the right of stockholders to call special meetings of stockholders;

     - impose significant transfer restrictions on United Metro common stock;

     - limit the right of stockholders to present proposals or nominate
       directors for election at annual meetings of stockholders; and

     - authorize the board of directors to issue preferred stock in one or more
       series without any action on the part of stockholders.

     These provisions could significantly impede the ability of the holders of
United Metro common stock to change management.

UNITED METRO HAS NO CURRENT INTENTION TO PAY DIVIDENDS

     United Metro's dividend policy following the spin-off will be determined by
its board of directors. Under Delaware law and United Metro's restated
certificate of incorporation, United Metro's board of directors will not be
required to declare dividends on any class of United Metro capital stock and
will be free to adopt the dividend policy it deems appropriate and to change its
dividend policy and practices from time to time. It is anticipated that United
Metro will not pay cash dividends to its stockholders.

                FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

     United Metro and Kiewit have made forward-looking statements in this
offering circular-prospectus that are subject to risks and uncertainties.
Forward-looking statements include the information concerning possible or
assumed future results of operations of United Metro and/or Kiewit. Also, when
we use words such as "believes," "expects," "anticipates" or similar
expressions, we are making forward-looking statements. You should note that many
factors, some of which are discussed elsewhere in this offering
circular-prospectus, could affect the future financial results of United Metro
and/or Kiewit and could cause those results to differ materially from those
expressed in the forward-looking statements contained in this offering circular-
prospectus.

                         THE DEBENTURE EXCHANGE OFFER,
                      THE SHARE EXCHANGE AND THE SPIN-OFF

BACKGROUND AND PURPOSE

     The debenture exchange offer is being made in connection with a proposal by
Kiewit to separate its materials business and construction business in a
spin-off that is intended to be tax-free to stockholders for U.S. federal income
tax purposes. The board of directors and management of Kiewit have determined
that separation of the materials business and the construction business is in
the best interests of Kiewit and Kiewit's stockholders. In reaching this
conclusion, Kiewit's board of directors and management considered the factors
discussed below.

  Key United Metro Employees

     Kiewit's restated certificate of incorporation generally restricts
ownership of Kiewit common stock to directors and employees of Kiewit and its
subsidiaries. Kiewit's policy of employee ownership originated many years ago as
a way of attracting and motivating top-quality employees. Historically, Kiewit
has maintained a relatively low salary structure and few retirement benefits for
its key employees in relation to its competitors, instead choosing to motivate
and reward employees by linking their personal economic well-being to the
performance and growth of Kiewit common stock.

     In recent years, as a result of United Metro's acquisition strategy, the
materials business has become an increasingly larger portion of Kiewit's overall
business. However, since the price of Kiewit common stock reflects the
performance of all of Kiewit's operations, it does not directly and distinctly
reflect the results of operations of the materials business. Kiewit believes
that materials employees would be better motivated if there were a clearer
connection between the results of their work and their economic rewards. This
lack of connection between effort and reward is particularly pronounced for key
employees of United Metro, whose annual compensation, in keeping with Kiewit's
core philosophy, is particularly low in relation to the value of their Kiewit
common stock.

     Kiewit would like to provide United Metro's key employees with a larger,
direct ownership interest in the materials business alone, undistorted by the
economic returns of the construction business. Kiewit believes that the future
of the materials business depends to a large degree on the continued efforts of
these individuals and that they will be much more and better motivated to
promote its financial success if they hold an increased interest solely in the
enterprise in which they are employed.

     By acquiring an increased equity interest in United Metro, which will
operate only the materials business, these employees' economic rewards will be
tied much more closely and directly to their performance. Each of United Metro's
key employees is expected to exchange all of his Kiewit common stock for United
Metro common stock in the share exchange. If they do, these employees' equity
ownership will change from an approximately 2% aggregate interest in Kiewit as
of February 17, 2000, to an approximately 6% aggregate interest in United Metro.

  Increased Ownership for All United Metro Employees

     The share exchange provides all United Metro employees who own Kiewit
common stock, approximately 60 individuals (including key employees), with the
opportunity to obtain a substantially larger, direct ownership interest in the
materials business that is unaffected by the results of the construction
business. Kiewit believes this increased correlation between these employees'
work performance and their stock-based financial rewards is essential to United
Metro's ability to better retain, attract and motivate its employees broadly as
a group. If all of the United Metro employees who own Kiewit common stock
exchange their Kiewit common stock for United Metro common stock in the share
exchange, these employees' equity ownership in United Metro (including the key
employees) will change from an approximately 3.4% aggregate interest in Kiewit
as of February 17, 2000 to an approximately 9.5% aggregate interest in United
Metro. This more closely aligns the economic interests of these United Metro
employees with United Metro's interests and is expected to motivate these
employees to work and compete more efficiently.
                                       22
<PAGE>   31

  Competition

     The management of United Metro believes that there are potential customers
who are reluctant to do business with United Metro because of its existing
relationship with Kiewit. These potential customers view the companies operating
the construction business within Kiewit's affiliated group as their direct
competitors. The perception that the materials business is owned and controlled
by Kiewit has limited United Metro's ability to obtain business from these
potential customers. The managers of United Metro believe that their ability to
make sales to and secure contracts from unrelated construction businesses would
be meaningfully improved if the materials business were separated from the
construction business, so that no entity owning or operating the construction
business would have control over or benefit economically from the materials
business.

THE SHARE EXCHANGE

     Kiewit is also offering Kiewit stockholders who are United Metro employees
the opportunity to exchange their shares of Kiewit common stock for shares of
United Metro common stock with an equal aggregate formula price. Kiewit's
restated certificate of incorporation generally restricts ownership of Kiewit
common stock to directors and employees of Kiewit and its subsidiaries.
Following the completion of the spin-off, United Metro employees will no longer
be employed by Kiewit or a subsidiary of Kiewit and will no longer meet the
requirements for owning Kiewit common stock. Therefore, they will be required to
sell any Kiewit common stock they then own back to Kiewit. To provide United
Metro employees with a larger, more direct stake in the materials business and
an alternative to selling their Kiewit common stock back to Kiewit for cash
immediately following the spin-off, Kiewit is offering Kiewit stockholders who
are United Metro employees the opportunity to exchange their shares of Kiewit
common stock for shares of United Metro common stock with an equal aggregate
formula price.

THE SPIN-OFF

     After the completion of the debenture exchange offer and the share
exchange, Kiewit will distribute the shares of United Metro common stock it then
holds as a dividend on a pro rata basis to holders of Kiewit common stock in the
spin-off. Kiewit stockholders will receive in the spin-off one share of United
Metro common stock for each share of Kiewit common stock held.

EFFECTS

     As a result of the spin-off, the debenture exchange offer and the share
exchange, United Metro will become a fully independent, separate company. Kiewit
debentureholders will be affected by the spin-off regardless of whether they
choose to participate in the debenture exchange offer.

CONSEQUENCES OF A DECISION NOT TO EXCHANGE

  United Metro Employees

     Kiewit debentureholders who are United Metro employees will cease to be
employees of Kiewit or a subsidiary of Kiewit after the spin-off. Consequently,
they will no longer meet the requirements for owning Kiewit debentures and will
be required to sell any Kiewit debentures they then own back to Kiewit.

  Kiewit Employees

     For those debentureholders who are Kiewit employees, the shares of Kiewit
common stock issuable on conversion of the Kiewit debentures will have a lower
aggregate formula price following the spin-off since that formula price will be
reduced by the book value of United Metro distributed as a dividend in the
spin-off.

                                       23
<PAGE>   32

CONSEQUENCES OF A DECISION TO EXCHANGE

  United Metro Employees

     Kiewit debentureholders who are United Metro employees and who exchange
some or all of their Kiewit convertible debentures in the debenture exchange
offer will receive at their option:

     - United Metro debentures convertible into shares of United Metro common
       stock in a transaction that is intended to be tax-free to
       debentureholders for U.S. federal income tax purposes; or

     - both new reduced principal amount Kiewit debentures convertible into
       shares of Kiewit common stock and shares of United Metro common stock.

     A United Metro employee who elects to receive new reduced principal amount
Kiewit debentures and United Metro common stock will be required to sell the new
Kiewit debentures back to Kiewit following the spin-off.

  Kiewit Employees

     Kiewit debentureholders who are Kiewit employees and who exchange some or
all of their Kiewit convertible debentures in the debenture exchange offer will
receive at their option:

     - United Metro debentures convertible into shares of United Metro common
       stock; or

     - both new reduced principal amount Kiewit debentures convertible into
       shares of Kiewit common stock and shares of United Metro common stock in
       a transaction that is intended to be tax-free to debentureholders for
       U.S. federal income tax purposes.

     A Kiewit employee who elects to receive United Metro debentures will be
required to sell the United Metro debentures back to United Metro following the
spin-off.

NO APPRAISAL RIGHTS

     Because none of the debenture exchange offer, share exchange or the
spin-off is a merger or consolidation giving rise to appraisal rights under
Section 262 of the Delaware General Corporation Law, no appraisal rights are
available to Kiewit stockholders or debentureholders in connection with these
transactions.

REGULATORY APPROVALS

     Kiewit and United Metro do not believe that any material federal or state
regulatory approvals will be necessary to consummate the debenture exchange
offer, the share exchange and the spin-off.

ACCOUNTING TREATMENT

  Debenture Exchange Offer

     The United Metro convertible debentures will be recorded at the same
carrying value as the Kiewit convertible debentures as reflected on Kiewit's
accounting records on the date of exchange. Accordingly, no gain or loss for
accounting purposes will be recognized by Kiewit as a result of the consummation
of the debenture exchange offer.

     The combined United Metro common stock and new reduced principal amount
Kiewit convertible debentures will be recorded at the same carrying value as the
Kiewit convertible debentures as reflected on Kiewit's accounting records on the
date of exchange. Accordingly, no gain or loss for accounting purposes will be
recognized by Kiewit as a result of the consummation of the debenture exchange
offer.

  Share Exchange

     The exchange of United Metro common stock for Kiewit common stock in the
share exchange will be computed on the basis of their respective formula prices
on the date of exchange. Accordingly, no gain

                                       24
<PAGE>   33

or loss for accounting purposes will be recognized by Kiewit as a result of the
consummation of the share exchange.

  Spin-off

     Shares of United Metro common stock that are distributed in the spin-off
will be accounted for as a dividend through a direct charge to retained
earnings. The amount of the dividend will be equal to Kiewit's carrying value of
the shares of United Metro common stock distributed.

     After the spin-off, the historical consolidated financial statements of
Kiewit will be retroactively restated, where appropriate, to disaggregate the
historical basis financial information of United Metro to present the business
of United Metro as discontinued operations. After the spin-off, United Metro
will be operated independently from Kiewit and will be reflected in the separate
financial statements of United Metro on an historical cost basis.

                          THE DEBENTURE EXCHANGE OFFER

TERMS OF THE DEBENTURE EXCHANGE OFFER

     Kiewit is offering holders of Kiewit convertible debentures the opportunity
to exchange their Kiewit convertible debentures for:

     - United Metro debentures convertible into United Metro common stock; or

     - both shares of United Metro common stock and new reduced principal amount
       Kiewit debentures convertible into shares of Kiewit common stock.

     The debenture exchange offer is being made in connection with a proposal by
Kiewit to separate its construction and materials businesses into two separate,
independent companies by distributing shares of United Metro common stock to
Kiewit stockholders in a spin-off that is intended to be tax-free for U.S.
federal income tax purposes.

     Holders of Kiewit convertible debentures who exchange their Kiewit
debentures for United Metro debentures will receive United Metro debentures in
the same principal amounts, bearing interest at the same rate as the Kiewit
debentures for which they were exchanged and due on October 31, 2010. The United
Metro debentures will be convertible into shares of United Metro common stock
with an initial aggregate formula price equal to the aggregate formula price of
the Kiewit common stock into which the holder's Kiewit debenture was
convertible.

     Holders of Kiewit convertible debentures who exchange their debentures for
United Metro common stock and new reduced principal amount Kiewit convertible
debentures will receive:

     - new reduced principal amount Kiewit debentures, bearing interest at the
       same rate as the Kiewit debentures for which they were exchanged and due
       on October 31, 2010; and

     - shares of United Metro common stock.

     The number of shares of United Metro common stock the holder of a new
reduced principal amount Kiewit debenture will receive will be equal to the
number of shares that holder would have received had he or she converted his or
her original Kiewit debenture prior to the spin-off and received the dividend of
United Metro common stock in the spin-off.

     In addition, Kiewit debentureholders who participate in the debenture
exchange offer will receive accrued interest on the Kiewit debentures they
tender up to and including the date of the consummation of the debenture
exchange offer. If the tendered debentures are pledged to Enterprise Bank, N.A.
or U.S. Bank, N.A., Kiewit will pay that interest to those banks up to the
amount of any interest accrued on the underlying loan. Any remaining accrued
interest on the debentures will be paid by Kiewit directly to the
debentureholder.

     All Kiewit convertible debentures properly tendered and not withdrawn will
be exchanged on the terms and conditions of the debenture exchange offer. Kiewit
will promptly return to debentureholders any Kiewit debentures not accepted for
exchange following the expiration of the debenture exchange offer.

     Kiewit is sending this document and related documents to debentureholders
who held Kiewit convertible debentures on or about             , 2000. On that
date, there were $          in aggregate principal amount Kiewit convertible
debentures outstanding, which were held by approximately
debentureholders.

     What Kiewit debentureholders will receive if they participate in the
debenture exchange offer depends on:

     - the series of the Kiewit convertible debentures they currently hold; and

     - the securities they elect to receive in exchange for their convertible
       debentures.

                                       26

     If you elect Choice 2:

     - the principal amount of the new Kiewit convertible debentures you receive
       will be equal to the principal amount of the outstanding Kiewit
       convertible debentures less the initial formula price of the United Metro
       common stock received in the debenture exchange offer; and

     - the number of shares of United Metro common stock you receive will be
       equal to the number of shares of United Metro common stock you would have
       received had you converted your original Kiewit debentures prior to the
       spin-off and received the dividend of United Metro common stock in the
       spin-off. In the spin-off, Kiewit stockholders will receive one share of
       United Metro common stock for each share of Kiewit common stock they
       hold.

EXCHANGE ALTERNATIVES

     The following tables illustrate what you would receive depending on the
choice you elect in the debenture exchange offer.

     The results in the tables below were prepared on the basis of the

    paid the then current formula price for the fraction of the share necessary
    to round the number of shares issuable on conversion up to the nearest whole
    number of shares.

FORMULA PRICE

     The formula price of Kiewit common stock is the per share price at which
Kiewit buys and sells shares of its common stock and is based on the adjusted
book value of Kiewit at the end of the previous year less the amount of declared
dividends during the current year. The estimated formula price per share of
Kiewit common stock on February 17, 2000 was $20.28 per share. This formula
price will be reduced in the event Kiewit pays a cash dividend prior to
completion of the debenture exchange offer.

     The formula price of United Metro common stock is the per share price at
which United Metro will buy shares of its common stock and is based on the
adjusted book value of United Metro at the end of the previous year, less the
amount of declared dividends during the current year. In addition to any
adjustments for declared dividends during the current year, the initial formula
price for United Metro common stock is also adjusted for the amount of any
capital contributions made by Kiewit to United Metro during fiscal year 2000
prior to the spin-off.

TRANSFER RESTRICTIONS

     The new reduced principal amount Kiewit debentures will be subject to
substantial transfer restrictions and will remain subject to the repurchase
agreement executed by the debentureholders at the time of initial purchase of
the Kiewit debentures. Specifically, the terms of the repurchase agreement
prohibit Kiewit debentureholders from transferring the Kiewit debentures in any
manner except in a sale to Kiewit. The repurchase agreement also requires the
holder to sell the Kiewit debentures back to Kiewit upon the holder's
termination of employment with Kiewit.

     The United Metro debentures will also be subject to substantial transfer
restrictions. Each holder of Kiewit debentures who elects to receive United
Metro debentures will be required to execute a repurchase agreement with United
Metro. Specifically, the terms of the repurchase agreement will prohibit United
Metro debentureholders from transferring the United Metro debentures in any
manner except in a sale to United Metro. The repurchase agreement will also
require the holder to sell the United Metro debentures back to United Metro if
the holder voluntarily terminates his or her employment with United Metro or
United Metro terminates his or her employment for cause.

DETERMINING TO PARTICIPATE IN THE DEBENTURE EXCHANGE OFFER

     Whether you should participate in the debenture exchange offer and which

EXCHANGE OF KIEWIT CONVERTIBLE DEBENTURES

     If all of the conditions to the debenture exchange offer are met, Kiewit
will accept for exchange Kiewit convertible debentures that have been validly
tendered and not properly withdrawn or deemed withdrawn prior to the expiration
date except as described in "-- Extension of Tender Period; Termination;
Amendment" on page 33. Kiewit may, subject to the rules under the Securities
Act, delay accepting or exchanging any Kiewit debentures in order to comply in
whole or in part with any applicable law. For a description of Kiewit's right to
delay, terminate or amend the debenture exchange offer, see "-- Extension of
Tender Period; Termination; Amendment" on page 33.

PROCEDURES FOR TENDERING KIEWIT CONVERTIBLE DEBENTURES

     To tender your Kiewit convertible debentures, you must send to Kiewit, by
registered mail, return receipt requested, the following documents to be
received by Kiewit before the expiration date for the debenture exchange offer:

     - a completed and executed letter of transmittal indicating: (1) the
       principal amount of Kiewit debentures tendered, and (2) whether you are
       exchanging the Kiewit debentures for: (a) United Metro debentures
       convertible into shares of United Metro common stock, or (b) shares of
       United Metro common stock and new reduced principal amount Kiewit
       debentures, and any other documents required by the letter of
       transmittal;

     - an executed United Metro repurchase agreement if you are exchanging the
       Kiewit debentures for United Metro debentures; and

     - the Kiewit convertible debentures.

Kiewit's address is listed on the back cover of this document.

     If Kiewit debentures have been pledged to a lender, the registered holder
of the pledged Kiewit debentures must make appropriate arrangements with the
lender for the valid tender of the Kiewit debentures. If, however, the lender is
Enterprise Bank, N.A. or U.S. Bank, N.A., Kiewit will arrange directly with
those banks for the delivery of the pledged Kiewit debentures to Kiewit. Kiewit
will deliver the United Metro debentures or the United Metro common stock and
new reduced principal Kiewit debentures issued in exchange for Kiewit debentures
directly to any lending institution to which the Kiewit debentures were pledged
if so directed by the registered holder of the Kiewit debentures in the holder's
letter of transmittal. If the United Metro debentures or United Metro common
stock and new reduced principal Kiewit debentures received in exchange for the
tendered Kiewit debentures are to be delivered to a lender other than Enterprise
Bank, N.A. or U.S. Bank, N.A., the letter of transmittal must state with
specificity the necessary information, including the name, address and contact
person of the lender, to effect the delivery. If a holder of pledged Kiewit
debentures does not designate the lending institution to which the United Metro
debentures or United Metro common stock and new reduced principal Kiewit
debentures received in exchange for tendered Kiewit debentures is to be
delivered, Kiewit may deliver the United Metro debentures or United Metro common
stock and new reduced principal Kiewit debentures to the exchanging
debentureholder, but reserves the right to deliver such securities directly to a
lending institution if Kiewit believes in good faith that the lending
institution is entitled to receive them under a borrowing arrangement with the
exchanging debentureholder.

     Persons who have pledged Kiewit debentures to a lender and who are
considering participation in the debenture exchange offer should consult with
the lender as to the effect of the debenture exchange offer on their loan
arrangements.

LOST OR DESTROYED KIEWIT CONVERTIBLE DEBENTURES

     If any Kiewit convertible debentures have been mutilated, destroyed, lost
or stolen, the debentureholder must:

     - furnish to Kiewit evidence, satisfactory to it in its discretion, of the
       ownership of and the destruction, loss or theft of the convertible
       debenture;
                                       32
<PAGE>   41

     - furnish to Kiewit indemnity, satisfactory to it in its discretion; and

     - comply with any other reasonable regulations Kiewit may prescribe.

KIEWIT'S INTERPRETATIONS ARE BINDING

     Kiewit will determine in its own discretion all questions as to the form of
documents, including notices of withdrawal, and the validity, form, eligibility,
including time of receipt, and acceptance for exchange of any tender of Kiewit
convertible debentures. This determination will be final and binding on all
tendering debentureholders. Kiewit reserves the right to:

     - reject any and all tenders of any Kiewit convertible debentures not
       properly tendered;

     - waive any defects or irregularities in the tender of Kiewit convertible
       debentures or any conditions of the debenture exchange offer either
       before or after the expiration date; and

     - request any additional information from any Kiewit debentureholder that
       Kiewit deems necessary.

     Neither Kiewit nor United Metro will be under any duty to notify tendering
debentureholders of any defect or irregularity in tenders or notices of
withdrawal.

WITHDRAWAL RIGHTS

     You may withdraw tenders of Kiewit convertible debentures at any time prior
to the expiration date and, unless Kiewit has accepted your tender as provided
in this document, after the expiration of 40 business days from the commencement
of the debenture exchange offer. If Kiewit:

     - delays its acceptance of Kiewit convertible debentures tendered for
       exchange;

     - extends the debenture exchange offer; or

     - is unable to accept Kiewit convertible debentures tendered for exchange
       under the debenture exchange offer for any reason,

then, without prejudice to Kiewit's rights under the debenture exchange offer,
Kiewit may retain Kiewit convertible debentures tendered, and those debentures
may not be withdrawn except as otherwise provided in this document, subject to
provisions under the Securities Exchange Act that provide that an issuer making
an exchange offer shall either pay the consideration offered or return tendered
securities promptly after the termination or withdrawal of the exchange offer.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by Kiewit at its address set forth on the back cover of this document.
The notice of withdrawal must:

     - specify the name of the person having tendered the Kiewit convertible
       debentures to be withdrawn; and

     - identify the principal amount of Kiewit convertible debentures to be
       withdrawn.

     If Kiewit convertible debentures have been delivered or otherwise
identified to Kiewit, then, before the release of the convertible debentures,
the withdrawing holder must also submit the serial numbers of the particular
convertible debentures to be withdrawn, and a signed notice of withdrawal with
signatures guaranteed by an eligible institution, unless the holder is an
eligible institution.

     Any Kiewit convertible debentures withdrawn will be deemed not to have been
validly tendered for exchange for purposes of the debenture exchange offer.
Properly withdrawn debentures may be retendered by following one of the
procedures described under "-- Procedures for Tendering Kiewit Convertible
Debentures" at any time on or before the expiration date.

     Except as otherwise provided above, any tender of Kiewit convertible
debentures made under the debenture exchange offer is irrevocable.

EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT

     Kiewit expressly reserves the right, in its discretion, for any reason,
including the non-satisfaction of the conditions for completion set forth below,
to extend the period of time during which the debenture exchange offer is open
or to amend the debenture exchange offer in any respect.

                                       33
<PAGE>   42

     If Kiewit materially changes the terms of or information concerning the
debenture exchange offer, Kiewit will extend the exchange offer. The SEC has
stated that, as a general rule, it believes that an offer should remain open for
a minimum of five business days from the date that notice of the material change
is first given. The actual length of time will depend on the particular facts
and circumstances. Subject to the preceding paragraph, the debenture exchange
offer will be extended so that it remains open for a minimum of ten business
days following the announcement if:

     - Kiewit changes the principal amount of Kiewit convertible debentures
       eligible for exchange or imposes a minimum condition; or

     - the debenture exchange offer is scheduled to expire within ten business
       days of announcing a material change.

     If the conditions indicated in the next section have not been met, Kiewit
reserves the right, in its sole discretion, so long as Kiewit convertible
debentures have not been accepted for exchange, to delay acceptance for exchange
of or exchange for any Kiewit convertible debentures or to terminate the
debenture exchange offer and not accept for exchange any Kiewit convertible
debentures.

     If Kiewit extends the debenture exchange offer, is delayed in accepting any
Kiewit convertible debentures or is unable to accept for exchange any Kiewit
convertible debentures under the debenture exchange offer for any reason, then,
without affecting Kiewit's rights under the debenture exchange offer, it may
retain all Kiewit convertible debentures tendered. These Kiewit convertible
debentures may not be withdrawn except as provided in "-- Withdrawal Rights"
above. Kiewit's reservation of the right to delay acceptance of any Kiewit
convertible debentures is subject to applicable law, which requires that Kiewit
pay the consideration offered or return the Kiewit convertible debentures
deposited promptly after the termination or withdrawal of the debenture exchange
offer.

     Kiewit will issue a press release or other public announcement no later
than 9:00 a.m., Omaha time, on the next business day following any extension,
amendment, non-acceptance or termination of the previously scheduled expiration
date.

CONDITIONS TO THE DEBENTURE EXCHANGE OFFER

     Kiewit has received a ruling from the IRS confirming that, based on certain
factual representation by Kiewit and United Metro, the debenture exchange offer,
the share exchange and the spin-off generally will be tax-free transactions for
U.S. federal income tax purposes. The debenture exchange offer will not be
completed unless that ruling remains in effect, as determined by Kiewit in its
sole discretion.

     Kiewit expressly reserves the right to abandon the debenture exchange offer
and not accept for exchange any Kiewit convertible debentures if the Kiewit
board of directors reasonably determines that any material change in the
business, financial condition, results of operations or prospects of Kiewit or
United Metro has occurred, or in any other circumstance, and that, as a result,
completion of the debenture exchange offer would no longer be in the best
interest of Kiewit and its stockholders. Kiewit also expressly reserves the
right to abandon the share exchange. If Kiewit abandons either the debenture
exchange offer or the share exchange, it will not complete the spin-off or the
other exchange.

     Kiewit also reserves the right to abandon the spin-off at any time prior to
the completion of the debenture exchange offer and the share exchange. If Kiewit
abandons the spin-off, it will not complete the debenture exchange offer or the
share exchange.

     Kiewit also expressly reserves the right, at any time or from time to time,
whether or not the conditions to the debenture exchange offer have been
satisfied, (1) to extend the expiration date or (2) if the Kiewit board of
directors determines for any reason that such action would be in the best
interest of Kiewit and its stockholders, to modify the debenture exchange offer
in any respect, by giving written notice of such extension or modification to
Kiewit debentureholders.

     The debenture exchange offer is not conditioned on any minimum principal
amount of Kiewit convertible debentures stock being tendered for exchange.

                       SELECTED HISTORICAL AND PRO FORMA
                            FINANCIAL DATA OF KIEWIT

     The following table presents selected historical and pro forma financial
data of Kiewit. The historical information as of and for each of the fiscal
years ended 1994 through 1998 is derived from Kiewit's historical consolidated
financial statements and the notes to those financial statements included
elsewhere in this offering circular-prospectus. The historical information for
the nine months ended September 30, 1998 and September 30, 1999 is derived from
the unaudited consolidated condensed financial statements included elsewhere in
this offering circular-prospectus which, in the opinion of management, reflect
all adjustments, which are of a recurring nature, necessary to present fairly
the financial position and results of operations and cash flows for the interim
periods. Results for the nine months ended September 30, 1999 and 1998 are not
necessarily indicative of the results of operations to be expected for the full
fiscal year.

(1) Completion of the share exchange, the debenture exchange offer and the
    spin-off has been assumed to be as of September 30, 1999 in the pro forma
    financial position data and as of December 28, 1997 in the pro forma results
    of operations data for the year ended December 26, 1998 and nine months
    ended September 30, 1999.

(2) The pro forma results of operations, per common share and financial position
    data assume the earnings statement and balance sheet accounts of United
    Metro have been removed, the share exchange, the debenture exchange offer
    and the spin-off have been completed, and Kiewit has made a $30 million
    capital contribution to United Metro.

(3) The 1994, 1995, 1996, 1997 and 1998, Kiewit dividends include $.1125, $.15,
    $.175, $.20 and $.225 for dividends declared in those years, respectively,
    but paid in January of the subsequent year.

(4) Pursuant to Kiewit's restated certificate of incorporation, the formula
    price calculation is calculated annually at the end of the fiscal year,
    except that adjustments to reflect dividends are made when declared.

(5) Ownership of Kiewit common stock is restricted to employees conditioned upon
    the execution of repurchase agreements which restrict employees from
    transferring the stock. Kiewit is generally required to purchase all of its
    common stock at the formula price. The aggregate redemption value of Kiewit
    common stock at September 30, 1999 was $546 million.

                       SELECTED HISTORICAL AND PRO FORMA
                         FINANCIAL DATA OF UNITED METRO

     The following table presents selected historical and pro forma financial
data of United Metro. The historical information as of and for each of the
fiscal years ended 1994 through 1998 is derived from United Metro's historical
consolidated financial statements and the notes to those financial statements
included elsewhere in this offering circular-prospectus. The historical
information for the nine months ended September 30, 1998 and September 30, 1999
is derived from the unaudited consolidated condensed financial statements
included elsewhere in this offering circular-prospectus which, in the opinion of
management, reflect all adjustments, which are of a recurring nature, necessary
to present fairly the financial position and results of operations and cash
flows for the interim periods. Results for the nine months ended September 30,
1999 and 1998 are not necessarily indicative of the results of operations to be
expected for the full fiscal year.

     For all historical periods presented, United Metro operated as a part of
Kiewit. Because United Metro did not operate as an independent company during
these periods, the data may not reflect the results of operations or the
financial condition which would have resulted if United Metro had operated as a
separate, independent company. In addition, the data may not necessarily be
indicative of United Metro's future results of operations or financial position.

</TABLE>

     Construction.  Revenues for the construction business increased $86 million
or 10% for the three months ended September 30, 1999 as compared to the same
time period in 1998. The increase is due to favorable market conditions in the
business sectors that Kiewit operates.

     Contract backlog at September 30, 1999 was $4.4 billion of which 6% is
attributable to foreign operations located in Canada. Domestic projects are
spread geographically throughout the U.S.

     Margins as a percentage of revenue on construction projects for the three
months ended September 30, 1999 were consistent with margins in the same time
period in 1998, increasing from 8.4% to 8.5%.

     Materials.  Revenues increased 33% to $110 million during the third quarter
1999 when compared to the same period in 1998. A continued strong market for
materials products in the Southwest that resulted in additional unit sales of
asphalt, ready mix and aggregates accounted for much of the increase. Additional
ballast sales at a quarry located in Wyoming plus the consolidation of Pacific
Rock Products, L.L.C. due to the increase in ownership from 40% to 100%, which
contributed $19 million, account for the balance of the increase.

     Margins increased 40% from $10 million to $14 million during 1999 compared
to the third quarter of 1998. Increased volumes and the consolidation of Pacific
Rock accounts for the increase in margins.

     General and Administrative Expenses.  General and administrative expenses
remained consistent with prior year levels as a proportionate increase in
administration costs was not necessary to support Kiewit's revenue growth.

     Investment (Loss) Income and Equity Earnings.  During the current period,
Kiewit determined that the decline in market value of an investment security was
other-than-temporary. This investment was written down to the current market
value and a loss of $18 million was recognized in the Statement of Earnings.
This investment had previously been carried at market value and the write-down
had been recorded as an unrealized loss as a separate component of other
comprehensive income. As a result, this write-down had no effect on total
comprehensive income or total redeemable common stock. Subsequent changes in the
market value of the security will be included as a separate component of
comprehensive income.

     Other, net.  Other income is primarily comprised of mine management fee
income from Level 3 Communications, Inc. and gains and losses on the disposition
of property, plant and equipment and other assets. The $10 million decrease
resulted primarily from a decrease in gains on equipment sales.

     Kiewit manages certain coal mines for Level 3. Fees for these services were
$9 million during the third quarter of 1999 and $10 million for the same time
period in 1998. Kiewit's fee is a percentage of adjusted operating earnings of
the coal mines. The mines managed by Kiewit for Level 3 earn the majority of
their revenues under long-term contracts. The remainder of the mines' sales are
made on the spot market where prices are substantially lower than those of the
long-term contracts. After a significant long-term contract

                                       37
<PAGE>   46

expires next year, adjusted operating earnings at the mines will decrease
substantially, thereby similarly decreasing the management fee earned by Kiewit.

     Additionally, the Minerals Management Service and Montana Department of
Revenue have issued assessments to the Level 3 mines for the underpayment of
royalties and production taxes. Level 3 is vigorously contesting the
assessments. If Level 3 pays these assessments, the payments could materially
decrease future mine management fees, but will not affect fees previously
received.

     Provision for Income Taxes.  The effective income tax rates in 1999 and
1998 differ from the federal statutory rate of 35% due primarily to state income
taxes.

RESULTS OF OPERATIONS -- NINE MONTHS 1999 VS. NINE MONTHS 1998

     Construction.  Revenues for the construction business increased $249
million or 11% from the same time period in 1998. The increase is due to
favorable market conditions in the business sectors that Kiewit operates.

     Margins on construction projects as a percentage of revenue for the nine
months ended September 30, 1999 were consistent with margins in the same period
in 1998, decreasing from 7.2% to 7.1%.

     Materials.  Revenues for the materials business increased 34% to $316
million from the same time period in 1998. A continued strong market for
materials products in the Southwest that resulted in additional unit sales of
asphalt, ready mix and aggregates accounted for much of the increase. Additional
ballast sales at quarries located in Wyoming and Utah plus consolidation of
Pacific Rock, due to the increase in ownership from 40% to 100%, which
contributed $38 million, account for the balance of the increase.

     Materials margins increased 72% from $18 million to $31 million when
compared to the same time period in 1998. Increased volumes and the
consolidation of Pacific Rock combined with the elimination of losses taken in
1998 for the Oak Mountain coal operations contributed to the increase.

     General and Administrative Expenses.  General and administrative expenses
decreased 3% for the nine months ended September 30, 1999. The decrease was
attributable to cost containment and reassignment of overhead personnel.

     Investment (Loss) Income and Equity Earnings.  During the current period,
Kiewit determined that the decline in market value of an investment security was
other-than-temporary. This investment was written down to the current market
value and a loss of $18 million was recognized in the Statement of Earnings.
This investment had previously been carried at market value and the write-down
had been recorded as an unrealized loss as a separate component of other
comprehensive income. As a result, this write-down had no effect on total
comprehensive income or total redeemable common stock. Subsequent changes in the
market value of the security will be included as a separate component of
comprehensive income.

     Other, net.  Other income is primarily comprised of mine management fee
income from Level 3 and gains and losses on the disposition of property, plant
and equipment and other assets. The $7 million decrease resulted primarily from
a decrease in the mine management fee.

     Kiewit manages certain coal mines for Level 3. Fees for these services were
$23 million for the nine months ended September 30, 1999 and $27 million for the
same time period in 1998. Kiewit's fee is a percentage of adjusted operating
earnings of the coal mines. The mines managed by Kiewit for Level 3 earn

                                       38

the majority of their revenues under long-term contracts. The remainder of the
mines' sales are made on the spot market where prices are substantially lower
than those of the long-term contracts. After a significant long-term contract
expires next year, adjusted operating earnings at the mines will decrease
substantially, thereby similarly decreasing the management fee earned by Kiewit.

     Additionally, the Minerals Management Service and Montana Department of

                                                     ======    ======
</TABLE>

     Construction.  Revenues for the construction business increased $583
million or 23.6% from the same time period in 1997. $210 million of the increase
in revenues resulted from several new domestic cogeneration facilities. Joint
ventures performing electrical work on railway systems contributed another $82
million. Another major factor was the "I-15" project, a $1.4 billion design
build joint venture, of which Kiewit's share is $780 million, to reconstruct 16
miles of interstate through the Salt Lake City, Utah area which contributed $135
million to the increase. Several new projects account for the remainder of the
increase.

     Contract backlog at December 26, 1998 was nearly $5 billion, of which 3.5%
is attributable to foreign operations located primarily in Canada. Domestic
projects are spread geographically throughout the U.S.

     Margins on construction projects as a percentage of revenue for the twelve
months ended December 26, 1998 decreased to 8.6% from 13% for the same time
period in 1997. Favorable resolutions of project uncertainties, change order
settlements and bonuses for cost savings and early completion increased margins
for the twelve months ended December 27, 1997. Margins in 1996 and 1995 were
9.6% and 7.7%, respectively.

     In September of 1997, a Presidential Decree was issued in Indonesia
affecting the construction and start-up dates for a number of private power
projects. As a result of the Decree and the continued fluctuations in the value
of the Indonesian currency, several projects in Indonesia for a U.S. client have
been suspended. The suspension had no material impact on Kiewit, as
substantially all payments have been received for work performed and the costs
of demobilizing the project were not significant. All amounts that have been
billed and received in excess of costs incurred on the suspended projects have
been deferred pending final resolution of these projects with the U.S. client
and its lenders.

     Materials.  Revenues for the materials business were up 20%, from $268
million to $322 million, for the twelve months ended December 26, 1998 as
compared to the same time period in 1997. Greater sales volume and higher
average selling prices for aggregates, ready mix concrete and asphalt products
resulted in a 27% increase which was offset by the decrease in revenues from the
Oak Mountain Coal operations. The investment in Oak Mountain was sold on June 9,
1998. The Oak Mountain investment was previously written off as an impaired
asset in December 1997. In 1998, Kiewit realized operating losses of $3 million.

     Margins from materials sales as a percentage of revenue for the twelve
months ended December 26, 1998 increased from 4% in 1997 to 6.5% in 1998. The
increase in margins was attributable to higher average selling

                                       39
<PAGE>   48

prices and improvements in the performance of recent acquisitions. Also
contributing to the increase was the elimination of losses from the Oak Mountain
Coal operations.

     General and Administrative Expenses.  General and administrative expenses
decreased in 1998. G & A expense, as a percent of revenue, decreased from 5.4%
in 1997 to 4.2% in 1998, as a proportionate increase in administration costs
were not necessary to support Kiewit's revenue growth.

     Investment Income, Net.  Net investment income decreased by $5 million. The
decrease was partially due to the increased interest expense on long-term debt
and gains on sales of marketable securities in 1997 which were not recurring
items.

     Other, Net.  Other income is primarily comprised of mine management fee
income from Level 3 and gains and losses on the disposition of property, plant
and equipment and other assets. The mine management fee increased by $2 million
while a decrease in the amount of equipment sold during 1998 resulted in a $3
million decrease in gains from sales.

     Kiewit manages certain coal mines for Level 3. Fees for these services were
$34 million in 1998 and $32 million in 1997. Kiewit's fee is a percentage of
adjusted operating earnings of the coal mines, as defined. The mines managed by
Kiewit for Level 3 earn the majority of their revenues under long-term
contracts. The remainder of the mines' sales are made on the spot market where
prices are substantially lower than those of the long-term contracts. As the
long-term contracts expire over the next two to five years, adjusted operating
earnings at the mines will decrease substantially, thereby similarly decreasing
the management fee earned by Kiewit.

     Additionally, the Minerals Management Service and Montana Department of
Revenue have issued assessments to the Level 3 mines for the underpayment of
royalties and production taxes. Level 3 is vigorously contesting the
assessments. If Level 3 pays these assessments, the payments could materially
decrease future mine management fees, but will not affect fees previously
received.

     Provision for Income Taxes.  The effective income tax rates in 1998 and
1997 differ from the expected rate of 35% primarily due to state income taxes
and prior year tax adjustments.

RESULTS OF OPERATIONS 1997 VS. 1996

     Revenue from each of Kiewit's segments for the twelve months ended December
27, 1997 and December 28, 1996 was (in millions).

</TABLE>

     Construction.  Construction revenues increased $414 million during 1997
compared to 1996. The consolidation of ME Holding Inc. (due to the increase in
ownership from 49% to 80%) contributed $261 million, almost two-thirds of the
increase. In addition to ME Holding, several large projects and joint ventures
became fully mobilized during the latter part of the year and were well into the
"peak" construction phase.

     Construction margins increased to 13% of revenue in 1997 as compared to 10%
in 1996. The favorable resolution of project uncertainties, several change order
settlements, and cost savings or early completion bonuses received during the
year contributed to this increase.

     Materials.  Material revenues increased 10% to $268 million in 1997 from
$243 million in 1996. The acquisition of additional plant sites accounts for 43%
of the increase in sales. The remaining increase was a result of the strong
market for material products in Arizona. This raised sales volume from existing
plant sites and allowed for slightly higher selling prices. The inclusion of $10
million of revenues from the Oak Mountain facility in Alabama also contributed
to the increase.

                                       40
<PAGE>   49

     Material margins decreased from 10% of revenue in 1996 to 4% in 1997.
Losses at the Oak Mountain facility in Alabama were the source of the decrease.
The materials margins from sources other than Oak Mountain remained stable as
higher unit sales and selling prices were offset by increases in raw materials
costs.

     General and Administrative Expenses.  General and administrative expenses
increased 11% in 1997 after deducting $17 million of expenses attributable to ME
Holding. Compensation and profit sharing expenses increased $9 million and $2
million, respectively, from 1996. The increase in these costs is a direct result
of higher earnings.

     Investment Income and Equity Earnings.  Investment income increased by $1
million in 1997 to $20 million.

     Interest Expense.  The decline in interest expense is due to the absence of
short-term borrowings which were repaid in 1996.

     Other, Net.  Other income is primarily comprised of gains and losses on the
disposition of construction equipment and mine management fees paid by Level 3.
A $6 million increase in gains on the sale of equipment and additional
miscellaneous income was partially offset by a decline in mine management fee
income.

     Provision for Income Taxes.  The effective income tax rates in 1997 and
1996 differ from the expected statutory rate of 35% primarily due to state
income taxes and prior year tax adjustments.

FINANCIAL CONDITION -- SEPTEMBER 30, 1999 VS. DECEMBER 26, 1998

     Kiewit's working capital increased $36 million or 7% during the first nine
months of 1999. Sources of cash primarily included $193 million of cash provided
by operations, $22 million in proceeds from the sale of property, plant and
equipment and $25 million from the issuance of Kiewit common stock. Uses of cash
primarily included stock repurchases of $39 million, dividends of $16 million,
purchases of marketable securities of $4 million, repayment of debt of $22
million, $36 million for the acquisition of materials operations and $45 million
for the purchase of property, plant and equipment. Kiewit anticipates investing
between $50 and $100 million annually in its construction and materials
businesses. In addition to normal spending, Kiewit expects to make significant
investments in construction joint ventures in 1999. Kiewit continues to explore
opportunities to acquire additional businesses. Other long-term liquidity uses
include the payment of income taxes and the payment of dividends. Kiewit's
current financial condition and borrowing capacity, together with anticipated
cash flows from operations, should be sufficient for immediate cash requirements
and future investing activities.

NEW ACCOUNTING PRONOUNCEMENT

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities", which
established accounting and reporting standards for derivative instruments and
for hedging activities. This statement is effective for all fiscal years
beginning after June 15, 2000. Management does not expect adoption of this
statement to materially affect Kiewit's financial statements as Kiewit has no
material derivative instruments or hedging activities.

YEAR 2000 UPDATE

     Kiewit's Year 2000 effort, which was comprised of internal updating and
replacement of computer systems and external coordination with its customers was
completed on schedule. Kiewit has not experienced any material Year 2000 related
difficulties.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Kiewit does not believe that its business is subject to significant market
risks arising from interest rates, foreign exchange rates or equity prices.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                     RESULTS OF OPERATIONS OF UNITED METRO

     The following discussion is based upon and should be read in conjunction
with United Metro's Consolidated Financial Statements, including the notes
thereto, included elsewhere in this offering circular-prospectus.

RESULTS OF OPERATIONS -- THIRD QUARTER 1999 VS. THIRD QUARTER 1998

     Revenue.  Revenue increased $27,769,633 to $116,882,523 during the third
quarter of 1999 when compared to the same period in 1998. A continued strong
market for materials products in the Southwest resulting in additional unit
sales, coupled with the consolidation of Pacific Rock Products, L.L.C., due to
the increase in ownership from 40% to 100%, which contributed $19,477,933,
account for most of the increase. Additional ballast sales at a quarry located
in Wyoming also contributed to the increase.

     Gross Profit.  Gross profit increased $6,154,502 from $11,421,226 in the
third quarter of 1998 to $17,575,728 in the same period of 1999. The inclusion
of the acquired materials business and greater sales volume account for the
increase in gross profits. Gross profits, as a percentage of revenue increased
from 13% to 15% between the two time periods primarily due to the consolidation
of Pacific Rock.

     General and Administrative Expenses.  General and administrative expenses
increased $858,895 to $6,152,012 in the third quarter of 1999 when compared to
the same time period in 1998. Increases in unit volumes and the inclusion of
Pacific Rock account for the additional expense. General and administrative
expenses as a percentage of revenue declined slightly between the quarters in
1999 and 1998.

     Other Income and Expense.  Other income declined $1,530,717 for the two
quarters in 1999 and 1998. The consolidation of Pacific Rock, due to the
increase in ownership from 40% to 100%, accounts for the reduction in equity
earnings.

     Income Tax Expense.  Income taxes differ from the federal statutory rate
primarily because of state income tax and percentage depletion.

RESULTS OF OPERATIONS -- NINE MONTHS 1999 VS. NINE MONTHS 1998

     Revenue.  Revenue increased $83,351,589, from $245,102,685 in 1998 to
$328,454,274 in 1999. Strong markets in the Southwest, the consolidation of
Pacific Rock, due to the increase in ownership from 40% to 100%, which
contributed $38,306,126, and additional ballast sales at quarries in Wyoming and
Utah account for most of the increase.

     Gross Profit.  Gross profit increased from $28,073,193 to $41,798,432 for
the nine months ended September 1999 when compared to the same time period in
1998. The inclusion of the acquired business and greater sales volume are the
primary reasons for the increase gross profits. Improved operating performance
at a newly developed quarry also contributed to the gross profit increase. Gross
profit as a percentage of revenue increased slightly between the two periods.
The consolidation of Pacific Rock is responsible for most of the percentage
increase.

     General and Administrative Expenses.  General and administrative expenses
increased $3,449,109 in 1999 when compared to the same nine-month period in
1998. Increases in unit volume and the inclusion of Pacific Rock accounts for
most of the additional expense. As a percentage of revenue, general and
administrative expenses declined from 6.2% to 5.7%.

     Other Income and Expense.  Other income declined $2,764,391 for the nine
months ended 1999 as compared to the same time period in 1998. The consolidation
of Pacific Rock accounts for the reduction in equity earnings.

     Income Tax Expense.  Income taxes differ from the federal statutory rate
primarily because of state income tax and percentage depletion.

RESULTS OF OPERATIONS 1998 VS. 1997

     Revenue.  Revenue increased 20% from $277,308,896 to $333,060,002 for the
twelve months ended December 26, 1998 as compared to the same period in 1997.
This increase in sales resulted from higher selling prices and increases in
sales volumes of aggregates, ready mix concrete and asphalt products.

     Gross Profit.  Gross profits decreased $119,420 for the twelve months ended
December 26, 1998 when compared to the same time period in 1997. Gross profit as
a percentage of revenue declined from 13% in 1997 to 10% in 1998. Increases in
cement and other costs, coupled with start up expenses incurred at a greenfield
quarry site offset higher selling prices and unit volume increases.

     General and Administrative Expenses.  General and administrative expenses
increased in 1998 when compared to the same time in 1997 from $16,277,521 in
1997 to $19,062,488 in 1998. As a percentage of revenue, this expense declined
slightly from 5.9% in 1997 to 5.7% in 1998. The overall increase in expense was
necessary to support sales volume increases and the expansion of product lines.

     Other Income and Expense.  Other income increased $836,819 during the
twelve months ended 1998 when compared to the same period in 1997. Increases in
investment income, primarily from better operating results at Pacific Rock were
responsible for the change. Higher interest expense and smaller gain from the
sale of equipment mitigated the investment income increase.

     Income Tax Expense.  Income tax expense differs from the federal statutory
rate primarily because of state income taxes and percentage depletion.

RESULTS OF OPERATIONS 1997 VS. 1996

     Revenue.  Revenue increased 13% to $277,308,896 in 1997 from $246,083,386
in 1996. The acquisition of additional plant sites coupled with a strong demand
for products in the Southwest is responsible for the increase. Sales price
increases also contributed to the overall rise in revenue.

     Gross Profit.  Gross profits increased from $31,724,548 to $35,019,575 for
the twelve months ended December 1997 when compared to the same time period in
1996. The gross profit increase is derived from additional plant sites and
increased sales in the Southwest. Gross profit as a percentage of revenue
remained constant for the two years, as higher selling prices were offset by
increases in cement prices and other direct costs.

     General and Administrative Expenses.  General and administrative expenses
increased $1,307,198 in 1997 when compared to 1996. As a percentage of revenue,
the overall rate declined from 6.1% to 5.9% between the two years. The increase
in expense was a result of plant expansion and growth in sales volumes.

     Other Income and Expense.  Other income increased $2,098,697 from 1996 to
1997. A slightly lower gain from the sale of equipment in 1997 was offset by an
increase in equity earnings from Pacific Rock and lower interest expense.

     Income Tax Expense.  Income tax expense differs from the federal statutory
rate primarily because of state income tax and percentage depletion.

FINANCIAL CONDITION -- SEPTEMBER 30, 1999

     Working capital increased $15,432,709 or 24% during the nine months ended
September 30, 1999. Sources of cash flow included cash provided by operations of
$10,143,108, proceeds from the sale of equipment of $1,216,238 and contributions
from Kiewit equaling $45,286,690. Uses of cash included $16,814,147 of capital
expenditures, $15,973,285 for payment of long term debt and $34,896,029 used in
acquisitions.

     United Metro intends to pursue a growth strategy that will require
substantial capital. These capital requirements will be in addition to amounts
necessary to replace existing equipment and make long term debt payments.
Capital requirements for acquisitions that are in excess of internally generated
funds are expected to

                                       43
<PAGE>   52

come from the issuance of debt securities or borrowings under credit facilities.
United Metro cannot accurately predict the timing, size or success of the growth
strategy and associated capital commitments.

ACCOUNTING PRONOUNCEMENT

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities", which
established accounting and reporting standards for derivative instruments and
for hedging activities. This statement is effective for all fiscal years
beginning after June 15, 2000. Management does not expect adoption of this
statement to materially affect United Metro's financial statements as United
Metro has no material derivative instruments or hedging activities.

YEAR 2000 UPDATE

     United Metro's Year 2000 effort, which was comprised of internal updating
and replacement of computer systems and external coordination with its customer
was completed on schedule. United Metro has not experienced any material Year
2000 related difficulties.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     United Metro does not believe that its business is subject to significant
market risks arising from interest rates, foreign exchange rates or equity
prices.

                            BUSINESS OF UNITED METRO

     United Metro operates aggregate, ready mix, asphalt and materials
operations in Arizona, Washington, Oregon, California, Wyoming, Utah and New
Mexico, with primary operations in Arizona, centered in the Phoenix and Tucson
metropolitan areas and in the Pacific Northwest, centered in the Vancouver,
Washington and Portland, Oregon metropolitan areas. Aggregate products are used
as highway construction materials, railroad ballast, decorative landscape rock,
roofing aggregate and building stone. United Metro also provides construction
services in and around Yuma, Arizona, focusing mainly on paving and related
projects. In 1999, United Metro produced in excess of 28 million tons of
construction materials and generated approximately $433 million of revenue.

     United Metro's Arizona and Pacific Northwest markets have been some of the
highest growth markets in the United States. Factors contributing to this growth
include large population increases and increases in public sector spending on
highway projects. United Metro believes that it should continue to experience
strong demand for its products, due in large part to federally funded highway
construction projects under the Transportation Equity Act for the 21st Century.
This act provides $218 billion for highway, transit and safety spending for
years 1998 through 2003, which represents a 40% increase in average annual
federal highway spending when compared to federal funding programs for the
preceding six years.

     United Metro has a favorable market position with the combination of its
strong market presence, extensive, high quality aggregate reserves, efficient
operations and experienced management team. United Metro has set high standards
for being a low cost producer, facilitating employee involvement, promoting
favorable community relations and being a safety conscious employer. It intends
to leverage these attributes with a growth strategy to expand its presence in
existing markets and to enter new markets with high-growth potential. United
Metro believes that there exists a significant opportunity for growth through
acquisitions given the large number of independent materials companies that
operate in the United States. These acquisition opportunities coupled with its
current expertise and the expected strong demand for its products provide for a
positive environment in which to pursue its growth oriented business plan.

INDUSTRY BACKGROUND/MARKET OVERVIEW

     United Metro is a vertically integrated manufacturer of aggregates,
ready-mix concrete and hot-mix asphalt for use primarily in construction.

  Aggregates

     Aggregates are a basic construction material, comprising sand, gravel and
crushed stone, used extensively for highway and infrastructure construction and
maintenance as well as for commercial and residential construction. In addition,
United Metro also produces aggregates for use as railroad track ballast. For
these purposes, aggregates have few, if any, substitutes. The United States
market for all aggregates was approximately 2.8 billion tons in 1998 with a
value of $13.5 billion. This represents an increase of 6.2% in volume and 9.6%
in dollar value above 1997 levels.

     Historically, demand for aggregates has been only moderately cyclical,
especially relative to other building materials such as cement and gypsum
wallboard. In addition to moderate cycles, the national per ton average price
for aggregates has not experienced an annual decline between 1985 and 1998.

     Spending on highway and infrastructure construction and maintenance
significantly drives demand for aggregates. Spending levels are influenced by
public sector expenditures for construction and regional economic conditions.
Residential and commercial construction spending is influenced by general
economic conditions and prevailing interest rates and consequently is generally
more cyclical than public construction spending. Demand is also seasonal because
of the impact of weather conditions on construction activity.

     The aggregates industry is currently undergoing significant consolidation,
although generally the industry remains fragmented nationally as well as in many
regional areas. The estimated market share of the top five producers was 25% in
1998. From 1980 to 1998, the number of independent producers of crushed stone in
the United States declined by 22% from approximately 1,865 to approximately
1,450, although crushed stone
                                       45
<PAGE>   54

consumption increased by 68%. From 1980 to 1998, the number of independent sand
and gravel producers declined by 19% from 4,512 to 3,642, although sand and
gravel consumption increased by 47%.

     Due to the high cost of transportation relative to the value of the
product, competition within the aggregates industry tends to be localized.
Generally, individual aggregate production sites compete for customers within a
limited geographic area, which may be as small as 20 to 30 miles depending on
local availability of suitable aggregates and the geographic density of demand.
As a result, the proximity of aggregate production sites to customers is an
important factor in competition for customers.

     There are four primary factors which limit the availability of economically
viable aggregates reserves in a particular market:

     - the geological existence of suitable aggregates within a particular
       market;

     - the physical characteristics of available aggregates and the difficulty
       in satisfying increasingly rigorous specifications required by customers;

     - the difficulty in and increasingly higher cost of obtaining the necessary
       permits for potential reserves; and

     - the feasibility of cost-effectively extracting, processing and delivering
       available reserves.

     In addition to factors that limit the availability of suitable aggregates,
increasing levels of operational, technical and financial sophistication in the
aggregates industry have rewarded efficient producers with a competitive
advantage in terms of their ability to meet the increasing demand for quality
aggregates and to satisfy increasingly demanding and technically sophisticated
customers.

     The difficulty and related expense of complying with environmental and
other regulations may make it difficult for small producers to open new
aggregate production sites, enter new markets and compete effectively. In
ongoing aggregate mining and processing, aggregates producers must adhere to
various mining regulations, including rules and regulations regarding:

     - dust and water emissions;

     - sediment and erosion control;

     - noise limitations;

     - wetlands protection;

     - reclamation of depleted quarry sites; and

     - the safety of blasting and other mining techniques.

     Often new aggregate production sites require, among other things, zoning
changes and local, state and federal permits and plans regarding mining,
reclamation and air and water emissions. Once appropriate zoning is secured and
approved, it is permanent. Generally, permits must be renewed every five years.
Their renewal can only be denied, however, if the controlling agency is able to
prove that the permit holder has repeatedly violated the set guidelines and has
not taken remedial action when notified of violations. New site approval
procedures may require the preparation of archaeological surveys, endangered
species studies and other studies to assess the environmental impact. Compliance
with these regulatory requirements necessitates a significant up-front
investment and adds to the length of time to develop a new site.

     Aggregates producers often face opposition from the communities in which
new aggregate production sites are to be located. Public concerns center on
noise levels and blasting safety, the visual impact of an aggregate production
site on neighboring properties and high volume of truck traffic. To respond to
these issues, producers must operate in a more sophisticated manner such as
developing blasting techniques to minimize surface vibrations and noise and
developing an effective community communications program. Producers are often
required to acquire larger tracts of property to allow for extended buffer zones
between aggregate production sites and surrounding properties and to invest
significant capital to improve road and highway access.

  Ready-mix Concrete

     Ready-mix concrete is a versatile, low-cost manufactured material the
construction industry uses in substantially all of its projects. It is a
stone-like compound that results from combining fine and coarse aggregates, such
as sand, gravel and crushed stone, with water, various admixtures and cement.
Ready-mix concrete can be manufactured in thousands of variations, which in each
instance may reflect a specific design use. Manufacturers of ready-mix concrete
generally maintain less than one day's requirements of raw materials and must
coordinate their daily material purchases with the time-sensitive delivery
requirements of their customers.

     Annual usage of ready-mix concrete in the United States is currently at a
record level and is projected to continue growing. According to the National
Ready-mix Concrete Association, total sales from production and delivery of
ready-mix concrete in the United States grew from $17.6 billion in 1996 to $19.3
billion in 1997, an increase of 9.7%, and to $21.3 billion in 1998, an increase
of 10.4%, and are expected to grow to $22.1 billion in 1999. Also according to
this industry association, the following segments of the construction industry
accounted for the following approximate percentages of total sales of ready-mix
concrete in the United States in 1998:

Total.....................................................     100%
</TABLE>

     Ready-mix concrete begins to harden when mixed and generally becomes
difficult to place within 60 to 90 minutes after mixing. This characteristic
generally limits the market for a permanently installed plant to an area within
a 25-mile radius of its location. Concrete manufacturers produce ready-mix
concrete in batches at their plants and use mixer and other trucks to distribute
and place it at the job sites of their customers. These manufacturers generally
do not provide paving or other finishing services that construction contractors
or subcontractors typically perform.

     Manufacturers generally obtain contracts through local sales and marketing
efforts they direct at general contractors, developers and home builders. As a
result, local relationships are very important.

     On the basis of information from the National Ready-mix Concrete
Association, in addition to vertically integrated manufacturers of cement and
ready-mix concrete, more than 3,500 independent producers currently operate a
total of approximately 5,300 plants in the United States. Larger markets
generally have numerous producers competing for business on the basis of price,
timing of delivery and reputation for quality and service. The typical ready-mix
concrete company is family-owned and has limited access to capital, limited
financial and technical expertise and limited exit strategies for its owners.
Given these constraints, many ready-mix concrete companies are finding it
difficult to both grow their businesses and compete effectively against larger,
more cost-efficient and technically capable competitors. These characteristics
present consolidation and growth opportunities.

  Hot Mix Asphalt

     Hot mix asphalt is a combination of approximately 95% aggregates bound
together by asphalt cement, also known as asphalt oil, a crude oil product. It
is used almost exclusively for paving and related applications.

     To make hot mix asphalt, the asphalt cement is heated, combined and mixed
with the aggregates at a hot mix asphalt facility. It is then loaded into trucks
for transport to the paving site. The trucks dump the hot mix asphalt into
hoppers located at the front of paving machines. The asphalt is placed, and then
is compacted using a heavy roller which is driven over the asphalt. Because the
temperature of the hot mix asphalt drops rapidly after spreading and because
compaction of the hot mix asphalt to achieve a specified density must take place
at temperatures above 175 degrees, compaction usually takes place within a
matter of minutes after the

                                       47
<PAGE>   56

paver spreads the hot mix asphalt. This generally also limits the market a hot
mix asphalt facility can serve to within a radius of approximately 20 miles
around the facility.

     Hot mix asphalt is recyclable. One hundred percent of an asphalt pavement
can be picked up, remixed with a portion of fresh materials, and used again.

     According to the National Asphalt Pavement Association, of the 2.27 million
miles of paved road in the U.S., 94% is surfaced with asphalt, including 65% of
the interstate system. United Metro believes the hot mix asphalt industry has
similar characteristics to the ready mix concrete industry in that there are
many local, independent operators as well as some large consolidators. In many
instances, hot mix asphalt will be provided in conjunction with paving services
by integrated paving contractors.

BUSINESS STRATEGY

     United Metro intends to continue to grow its business through a four-part
business strategy. First, United Metro plans to continue to build value in
markets currently served. In accomplishing this objective, United Metro will
strive for significant amounts of negotiated work that command higher margins by
continuing its focus on customer satisfaction and loyalty and continuing its
efforts to retain and improve upon its market share leadership. United Metro
also will continue to invest in technology to develop more efficient and
service-oriented truck dispatching, improve production methods to lower costs
and maintain superior equipment maintenance standards.

     Second, United Metro plans to expand its presence in existing markets
through acquisitions in exchange for cash or debt securities. United Metro
should have the opportunity to purchase smaller materials companies that operate
in or near current operations, as these markets remain fragmented and include a
large number of family-owned businesses facing inter-generational transition
issues. Successful acquisition of additional operations will allow United Metro
to eliminate duplicate overhead functions, improve efficiencies through the use
of newer technologies and benefit from cost savings derived from economies of
scale in operations and the purchasing of parts and supplies.

     Third, United Metro plans to enter, via acquisition in exchange for cash or
debt securities, new high-growth potential markets. Metropolitan communities
with high rates of expected population growth, coupled with greater than average
increases in spending on retirement and leisure activities, are some of the
variables that are considered in selecting an area for expansion. United Metro
has begun to implement this strategy with its recent acquisition of a materials
operation located in Northern California. This business is an integrated
supplier of high quality aggregates, ready mix concrete and asphalt. It serves
the rapidly expanding market between San Francisco and Sacramento.

     Finally, United Metro will seek to acquire and develop additional strategic
aggregate reserves in selected markets. The successful implementation of this
strategy element will not only replace reserves consumed by operations, but will
enhance United Metro's competitive cost position by the ownership of reserves in
attractive locations.

     Since 1992, United Metro has acquired nine companies and developed one
greenfield site in the implementation of its four-part strategy. Revenues have
increased from $40 million in 1992, to approximately $433 million for 1999 and
production tonnage has grown from 5.5 million tons in 1992, to in excess of 28
million tons in 1999. United Metro intends to continue its disciplined
investment approach to achieve profitable growth through acquisitions.

OPERATIONS

     United Metro is organized into four operating divisions: Arizona
Operations, Pacific Northwest Operations, Northern California Operations and
Quarries Operations. United Metro believes that a decentralized management
structure allows for a quicker reaction to localized events and a more
profitable operation. Each division is responsible for maintenance and operation
of significant investments in fixed plant assets and a substantial mobile
equipment fleet. Each operation also is charged with customer relations,
dispatching of

                                       48
<PAGE>   57

delivery vehicles, quality control, scheduling of production and the development
and maintenance of certain computer systems.

     United Metro is a vertically integrated provider of aggregates, ready-mix
concrete and asphalt products. Its operations employ approximately 2,300 people.
United Metro operates 60 ready-mix batch plants or asphalt plants at 21
locations in Arizona, California, Oregon and Washington. Its aggregates
operations are located in Arizona, California, New Mexico, Utah, Washington and
Wyoming. United Metro manages a truck fleet of about 1,000 vehicles, 900 of
which are owned and 100 of which are either leased on a long-term basis or
managed on a day-to-day rental basis. In 1999, United Metro's combined
operations produced and sold in excess of 28 million tons of aggregates
consisting of construction materials, ballast, highway aggregates, roofing
aggregates, concrete block aggregates and landscape rock products. Its Arizona
operation also manages a construction service business in the Yuma, Arizona
area.

     United Metro's executive management provides its four operating divisions
with strategic planning, corporate development and acquisitions and operations
oversight. United Metro also has a centralized administrative staff that
provides labor relations, various accounting functions, legal, tax planning and
compliance, equipment purchasing and equipment maintenance support.

RESERVES

     United Metro estimates that its total recoverable aggregates reserves are
in excess of 550 million tons. The yield from the mining of these reserves is
based on an estimate of volume that can be economically extracted to meet
current market and product applications. United Metro's mining plans are
developed by experienced mining engineers and operating personnel using drilling
and geological studies in conjunction with mine planning software. In certain
instances, reserve extraction is limited to phases or yearly amounts. Various
properties also have reserves under lease that have not been included in a
mining permit. These reserves have been excluded from United Metro's recoverable
reserve estimate.

     United Metro owns about 170 million tons of aggregates reserves and leases
another 380 million tons of aggregates reserves. United Metro's leases usually
require royalty payments based on either revenue derived from the location or an
amount for each ton of materials removed and sold from a site and have terms
ranging from one year to 27 years. Most of its long-term leases also provide an
option for the lease to be renewed.

PRODUCTS

     Aggregates.  United Metro primarily sells to third parties and utilizes
internally various types of aggregate products. The production of these products
typically involves extracting the material, crushing and sizing the material and
shipping it to the customer using either trucks or rail. Approximately 37% of
the aggregates produced in 1999 were used internally in the production of
value-added concrete and asphalt products.

     Ready-mix Concrete.  United Metro produces ready-mix concrete by combining
aggregates, cement, water and additives. The additives allow United Metro to
customize the product to customer specifications for overall strength, drying
speed and other properties. Product ingredients are combined at a batch plant
site and loaded into a mixer truck for delivery to the customer's location.

     Asphalt.  United Metro also produces and sells asphalt products. Asphalt is
a mixture of aggregates and asphalt oil. The asphalt oil is heated and combined
at a plant site and then loaded into dump trucks for transit to the customer's
location. Customer specifications can require the use of certain types or sizes
of aggregates and/or varying proportions of aggregates and asphalt oil.

CUSTOMERS

     United Metro markets to a wide variety of customers including street and
highway contractors, industrial and residential contractors, public works
contractors, wholesalers and retailers of decorative rock products, interstate
railroads and manufacturers of concrete block products. A substantial amount of
produced material is used in publicly funded projects, but no single customer
accounts for more than 3% of sales.
                                       49
<PAGE>   58

COMPETITION

     Due to the high cost of transportation, the construction materials business
is highly dependent on the availability of high quality aggregates proximate to
customers and production facilities. While price is an important factor in the
customer's purchase decision, qualitative factors such as response time,
reliability and product quality influence the purchase decision as well. With
much of the industry consisting of small to medium sized independent firms,
economies of scale, good site locations and technical knowledge will often
provide a competitive advantage. While United Metro believes it possesses these
attributes in the markets it serves, in certain segments of those markets it
competes directly with integrated materials companies that have greater
financial resources. It is also possible that competitors with a lower cost
structure or a willingness to accept lower margins than United Metro may have an
advantage on price sensitive projects.

EMPLOYEES

     United Metro employs approximately 2,300 people. Of these, about 400 are
officers, operations management, sales personnel, technical staff,
administrative personnel and clerical staff. Approximately 1,600 employees are
represented by labor unions under collective bargaining agreements and
approximately 300 are non-union craft employees. The collective bargaining
agreements have multi-year terms and expiration dates spread out over a period
of time. These agreements call for specified wage rates, payments to pension
plans or benefit trusts and require United Metro to comply with various
workplace rules. United Metro considers relations with its employees to be good.

GOVERNMENTAL AND ENVIRONMENTAL REGULATION

     United Metro's facilities are subject to various evolving federal, state
and local laws and regulations relating to the environment, including those
relating to discharges to air, water and land, the handling and disposal of
solid and hazardous waste and the cleanup of properties affected by hazardous
substances. Certain environmental laws impose substantial penalties for
non-compliance and others, such as the federal Comprehensive Environmental
Response, Compensation and Liability Act, as amended, impose strict,
retroactive, joint and several liability upon persons responsible for releases
of hazardous substances.

     United Metro continually evaluates whether it must take additional steps at
its locations to ensure compliance with certain environmental laws. United Metro
believes that its operations are in substantial compliance with applicable laws
and regulations and that any noncompliance is not likely to have a material
adverse effect on its business, financial position, results of operations or
cash flows. However, future events, such as changes in, or modified
interpretations of, existing laws and regulations or enforcement policies, or
further investigation or evaluation of the potential health hazards of certain
products or business activities, may give rise to additional compliance and
other costs that could have a material adverse effect on United Metro's
business.

     United Metro, as well as other companies in the aggregates industry,
produces certain products containing varying amounts of crystalline silica.
Excessive and prolonged inhalation of very small particles of crystalline silica
has been associated with non-malignant lung disease. The carcinogenic potential
of excessive exposure to crystalline silica has been evaluated for over a decade
by a number of research groups including the International Agency for Research
on Cancer, the National Institute for Occupational Safety and Health and the
National Toxicology Program, a part of the Department of Health and Human
Services. Results of various studies have ranged from classifying crystalline
silica as a probable to a known carcinogen. Other studies concluded higher
incidences of lung cancer in some operations were due to cigarette smoking, not
silica. Governmental agencies, including the Occupational Safety and Health
Administration and Mine Safety Health Administration, coordinate to establish
standards for controlling permissible limits on crystalline silica. United Metro
believes it currently meets government guidelines for crystalline silica
exposure and will continue to employ advanced technologies as they become
available to ensure worker safety and to comply with all applicable regulations.

     United Metro believes that its compliance with environmental laws has not
had a material adverse effect on its business, financial position, results of
operations or cash flows.
                                       50

LEGAL PROCEEDINGS

     From time to time, United Metro has been involved in various legal
proceedings relating to its operations and properties, all of which it believes
are routine in nature and incidental to the conduct of its business. Although
the ultimate legal and financial liability associated with such proceedings
cannot be estimated with certainty, United Metro believes, based on its
examination of such matters, that none of these proceedings, if determined
adversely, would have a material adverse effect on its business, financial
position, results of operations or cash flows.

                               BUSINESS OF KIEWIT

     Kiewit, together with its subsidiaries, is one of the largest construction
contractors in North America and also owns materials businesses. Kiewit was
incorporated in Delaware in 1997 to continue a construction business founded in
Omaha, Nebraska in 1884.

THE CONSTRUCTION BUSINESS

     The construction business is conducted by operating subsidiaries of Kiewit.
Kiewit and its joint ventures perform construction services for a broad range of
public and private customers primarily in the United States and Canada. New
contract awards during 1999 were distributed among the following construction
markets (approximately, by number): power, heat, cooling -- 34%, transportation
(including highways, bridges, airports, railroads, and mass transit) -- 33%,
commercial buildings -- 27%, water supply/dams -- 3%, oil and gas -- 2% and
other markets -- 1%.

     Kiewit primarily performs its services as a general contractor. As a
general contractor, Kiewit is responsible for the overall direction and
management of construction projects and for completion of each contract in
accordance with its terms, plans, and specifications. Kiewit plans and schedules
the projects, procures materials, hires workers as needed, and awards
subcontracts. Kiewit generally requires performance and payment bonds or other
assurances of operational capability and financial capacity from its
subcontractors.

  Contract Types

     Kiewit performs its construction work under various types of contracts,
including fixed unit or lump-sum price, guaranteed maximum price, and
cost-reimbursable contracts. Contracts are either competitively bid and awarded
or negotiated. Kiewit's public contracts generally provide for the payment of a
fixed price for the work performed. Profit on a fixed-price contract is realized
on the difference between the contract price and the actual cost of
construction, and the contractor bears the risk that it may not be able to
perform all the work for the specified amount. Construction contracts generally
provide for progress payments as work is completed, with a retainage to be paid
when performance is substantially complete. Construction contracts frequently
contain penalties or liquidated damages for late completion and infrequently
provide bonuses for early completion.

  Government Contracts

     Public contracts accounted for approximately 76% of the combined prices of
contracts awarded to Kiewit during 1999. Most of these contracts were awarded by
government and quasi-government units under fixed price contracts after
competitive bidding. Most public contracts are subject to termination at the
election of the government. In the event of termination, the contractor is
entitled to receive the contract price on completed work and payment of
termination related costs.

COMPETITION

     A contractor's competitive position is based primarily on its prices for
construction services and its reputation for quality, timeliness, experience,
and financial strength. The construction industry is highly competitive and
lacks firms with dominant market power. In 1999, Engineering News Record, a
construction trade publication, ranked Kiewit as the eighth largest United
States contractor in terms of 1998 revenue and 14th largest in terms of 1998 new
contract awards. It ranked Kiewit first in the transportation market in terms of
1998 revenue.

DEMAND

     The volume and profitability of Kiewit's construction work depends to a
significant extent upon the general state of the economies of the United States
and Canada, and the volume of work available to contractors. Fluctuating demand
cycles are typical of the industry, and such cycles determine to a large extent
the degree of competition for available projects. Kiewit's construction
operations could be adversely affected

                                       52
<PAGE>   61

by labor stoppages or shortages, adverse weather conditions, shortages of
supplies, or governmental action. The volume of available government work is
affected by budgetary and political considerations. A significant decrease in
the amount of new government contracts, for whatever reason, would have a
material adverse effect on Kiewit.

BACKLOG

     At the end of 1999, Kiewit had backlog (anticipated revenue from
uncompleted contracts) of approximately $4 billion, a decrease from
approximately $4.9 billion at the end of 1998. Of current backlog, approximately
$1 billion is not expected to be completed during 2000. In 1999, Kiewit was low
bidder on 165 jobs with total contract prices of approximately $1.5 billion, an
average price of approximately $9.3 million per job. There were 19 new projects
with contract prices over $20 million, accounting for approximately 63% of the
successful bid volume.

JOINT VENTURES

     Kiewit frequently enters into joint ventures to efficiently allocate
expertise and resources among the venturers and to spread risks associated with
particular projects. In most joint ventures, if one venturer is financially
unable to bear its share of expenses, the other venturers may be required to pay
those costs. Kiewit prefers to act as the sponsor of its joint ventures. The
sponsor generally provides the project manager, the majority of
venturer-provided personnel, and accounting and other administrative support
services. The joint venture generally reimburses the sponsor for such personnel
and services on a negotiated basis. The sponsor is generally allocated a
majority of the venture's profits and losses and usually has a controlling vote
in joint venture decision making. In 1999, Kiewit derived approximately 61% of
its joint venture revenue from sponsored joint ventures and approximately 39%
from non-sponsored joint ventures. Kiewit's share of joint venture revenue
accounted for approximately 25% of its 1999 total revenue.

THE MATERIALS BUSINESS

     Several of Kiewit's subsidiaries, located in Arizona, Washington, Oregon,
California, Wyoming, Utah and New Mexico, produce construction materials,
including ready-mix concrete, asphalt, sand and gravel, landscaping materials
and railroad ballast. As a result of the spin-off, substantially all of these
materials operations will no longer be a part of Kiewit. They will be owned and
operated by United Metro.

LOCATIONS

     Kiewit structures its construction operations around 20 principal operating
offices located throughout North America, including its headquarters located in
Omaha, Nebraska. Through its decentralized system of management, Kiewit has been
able to quickly respond to changes in the local markets. At the end of 1999,
Kiewit had current projects in 47 states, Puerto Rico, Washington, D.C. and 8
Canadian provinces.

PROPERTIES

     Kiewit's headquarters facilities are located in Omaha, Nebraska and are
owned by Kiewit. Kiewit also has 19 principal district offices in its
construction operations, 15 of which are located in owned facilities and 4 which
operate from leased facilities. Kiewit also has 14 area offices in its
construction operation, 2 of which are owned facilities and 12 of which are
leased facilities. Kiewit owns or leases numerous shops, equipment yards,
storage facilities, warehouses and construction material quarries. Since
construction projects are inherently temporary and location-specific, Kiewit
owns approximately 1,100 portable offices, shops and transport trailers. Kiewit
has a large equipment fleet, including approximately 5,100 trucks, pickups and
automobiles and 3,800 heavy construction vehicles, such as graders, scrapers,
backhoes and cranes. Joint ventures in which Kiewit is a participant also own an
approximate additional 1,800 portable offices, shops and transport trailers, 600
trucks, pickups and automobiles and 1,000 heavy construction vehicles.

ENVIRONMENTAL PROTECTION

     Compliance with federal, state, and local provisions regulating the
discharge of materials into the environment, or otherwise relating to the
protection of the environment, has not and is not expected to have a material
effect upon the capital expenditures, earnings, or competitive position of
Kiewit and its subsidiaries.

EMPLOYEES

     At the end of 1999, Kiewit and its majority-owned subsidiaries employed
approximately 20,300 people. Of these, approximately 2,300 were employees of
United Metro and its subsidiaries.

 SECURITY OWNERSHIP OF UNITED METRO COMMON STOCK BY CERTAIN BENEFICIAL OWNERS,
                DIRECTORS AND EXECUTIVE OFFICERS OF UNITED METRO

     The table below shows information about the expected ownership of United
Metro common stock as of the date of the spin-off by each of United Metro's
directors and the four most highly compensated executive officers in 1999 and
each person who is expected to beneficially own more than 5 percent of United
Metro common stock. The table also shows the expected ownership of United Metro
common stock by all of the directors and executive officers as a group as of
that date. The ownership information presented below with respect to all
persons:

     - is based on the ownership of United Metro common stock after the
       completion of the debenture exchange offer, the share exchange and the
       spin-off;

     - assumes that, in the share exchange, the persons listed below who are
       employees of United Metro exchanged any shares of Kiewit common stock
       they held for shares of United Metro common stock;

     - assumes that, in the debenture exchange offer, the persons listed below
       who are employees of United Metro exchanged any Kiewit convertible
       debentures they held for United Metro convertible debentures;

     - assumes that, in the debenture exchange offer, the persons listed below
       who are employees of Kiewit exchanged any Kiewit convertible debentures
       they held for both new reduced principal amount Kiewit convertible
       debentures and shares of United Metro common stock;

     - assumes a formula price for Kiewit common stock immediately prior to the
       spin-off of $20.28 per share, the estimated formula price as of February
       17, 2000;

     - assumes a formula price for United Metro common stock of $6.58 per share;

     - reflects the beneficial ownership of Kiewit common stock at January 3,
       2000 and the distribution ratio of one share of United Metro common stock
       for each share of Kiewit common stock in the spin-off, and the United
       Metro common stock split necessary to achieve that ratio; and

     - assumes no change in beneficial ownership of Kiewit common stock between
       January 3, 2000 and the date of the spin-off.

"Beneficial ownership" means the sole or shared power to vote, or to direct the
voting of, a security, or the sole or shared power to dispose of, or to direct
the disposition of, a security. A person is deemed, as of any date, to have
"beneficial ownership" of any security that such person has the right to acquire
within 60 days after such date.

DIRECTOR COMPENSATION

     Directors of United Metro will not receive directors' fees.

OTHER COMPENSATION AND EQUITY PROGRAMS

     United Metro intends to implement a discretionary bonus program for its
stockholder employees. United Metro anticipates that any bonuses under this
bonus program will be paid in January of each year during which the plan is in
effect. The amount of any bonuses and the determination of the individuals to
whom bonuses may be paid will be determined by the United Metro board of
directors and management in their sole discretion.

     Kiewit has historically offered certain of its employees the opportunity to
purchase securities in annual common stock and debenture offerings. The Kiewit
board of directors and management, in their sole discretion, select the
employees to whom Kiewit's securities will be offered and determine the amount
of securities to be offered. United Metro intends to follow Kiewit's prior
practice by regularly selling United Metro common stock and convertible
debentures to United Metro employees in annual offerings. However, although
United Metro intends to follow Kiewit's prior practice, United Metro is not
required to offer its securities in any particular year, nor is United Metro
obligated to offer securities to any particular employee, whether or not that
employee is already a security holder of United Metro, in any particular year.

          COMPARISON OF OUTSTANDING KIEWIT CONVERTIBLE DEBENTURES AND
           NEW REDUCED PRINCIPAL AMOUNT KIEWIT CONVERTIBLE DEBENTURES

     Each series of outstanding Kiewit debentures is issued in fully registered
form under an indenture, dated July 1, 1986, as amended by a First Supplemental
Indenture, dated March 31, 1998, between Kiewit and U.S. Bank, N.A. The
indenture is qualified pursuant to the Trust Indenture Act of 1939. The
indenture does not limit the aggregate principal amount of debentures which may
be issued and provides that debentures may be issued from time to time in one or
more series. The terms of the outstanding Kiewit debentures include those stated
in the indenture and those made a part of the indenture by reference to the
Trust Indenture Act of 1939 as in effect on the date of the indenture.

     The new reduced principal Kiewit convertible debentures will be issued
under the same indenture as the outstanding Kiewit convertible debentures.

     The following is a comparison of the material terms of the outstanding
Kiewit convertible debentures and the new reduced principal amount Kiewit
debentures and the terms of the repurchase agreement required to be executed by
a holder of a Kiewit debenture.

BASIC FEATURES

     As of February 17, 2000, there were three series of Kiewit convertible
debentures outstanding in an aggregate principal amount of $13,160,000: Series
1997, Series 1998 and Series 1999. There are three series of new reduced
principal Kiewit convertible debentures being offered in the debenture exchange
offer: Series 1997A, Series 1998A and Series 1999A. The outstanding Kiewit
convertible debentures and the new reduced principal amount Kiewit convertible

CONVERSION RIGHTS

     If the outstanding Kiewit convertible debentures are not converted into
shares of Kiewit common stock during the one month applicable conversion period
described above, the conversion right is lost. Prior to exercising the
conversion right, a debentureholder must have executed a repurchase agreement
pertaining to all Kiewit common stock acquired by the holder. The conversion
rights of the outstanding Kiewit convertible debentures will be adjusted to
reflect stock splits, stock dividends, stock reclassifications or certain
corporate reorganizations between the date of purchase of the debentures and the
date of conversion.

                                       70
<PAGE>   79

     The new reduced principal amount Kiewit convertible debentures will have
identical conversion rights. Similarly, debentureholders must have executed a
repurchase agreement pertaining to Kiewit common stock prior to conversion.

OWNERSHIP AND TRANSFER RESTRICTIONS

     Holders of outstanding Kiewit convertible debentures are parties to
repurchase agreements under which they agree not to transfer the debentures
except in a sale to Kiewit. Kiewit must purchase any debentures offered to it by
debentureholders. The repurchase agreement also provides that the debentures
must be sold back to Kiewit upon the death or retirement of the purchaser of the
debenture or the termination of the debentureholder's employment with Kiewit or
its subsidiaries. In any of the above-described circumstances, Kiewit will buy
back the debentures at a price equal to the principal amount of the debentures,
together with accrued interest from the last interest payment date to the date
of such purchase at the stated rate. No payment is made by Kiewit with respect
to the original bond premium. In the event Kiewit is offered some, but not all,
of a debentureholder's debentures, Kiewit may purchase all of such holder's
debentures.

     New reduced principal amount Kiewit debentures received in the debenture
exchange offer will remain subject to the repurchase agreement executed by the
debentureholder at the time of the initial purchase of the Kiewit debentures.

REDEMPTION

     Upon not less than ten days' written notice, Kiewit may, at its option,
redeem all, but not less than all, of the outstanding Kiewit convertible
debentures of any given series at the principal amount thereof, together with
accrued interest from the last interest payment date to the date fixed for
redemption at the stated rate. No payment is made by Kiewit with respect to the
original bond premium. Kiewit may not redeem outstanding Kiewit debentures of
any series during the one-month conversion period applicable to that series.

     Kiewit has identical redemption rights with respect to the new reduced
principal amount Kiewit convertible debentures.

MODIFICATION OF THE INDENTURE

     The indenture permits modification or amendment with the consent of the
holders of not less than two-thirds in principal amount of each series of
debentures, but no modification of the terms of payment, conversion rights, or
the percentage required for modification will be effective against any
debentureholder without such holder's consent.

     Both the outstanding Kiewit convertible debentures and the new reduced
principal amount Kiewit convertible debentures are issued under the indenture.

EVENTS OF DEFAULT AND WITHHOLDING OF NOTICE TO DEBENTUREHOLDERS

     The indenture provides for the following events of default with respect to
each series of the outstanding and new reduced principal amount Kiewit
convertible debentures: (1) failure to pay interest upon any of the debentures
of such series when due, continued for a period of 60 days, and (2) failure to
pay principal of the debentures of such series when due, continued for a period
of 60 days.

     The trustee under the indenture, within 90 days after the occurrence of a
default with respect to a particular series of debentures, is to give the
holders of debentures of such series notice of all defaults known to the
trustee, unless cured prior to the giving of such notice, provided that, except
in the case of default in the payment of principal or interest on any of the
debentures of such series, the trustee may withhold such notice if and so long
as it in good faith determines that the withholding of such notice is in the
interest of the holders of debentures of such series.

     Upon the happening and during the continuance of a default with respect to
a particular series of debentures, the trustee may declare the principal of all
the debentures of such series and the interest accrued

                                       71
<PAGE>   80

thereon due and payable, but if the default is cured, the holders of a majority
of such debentures may waive all defaults and rescind such declaration. Subject
to the provisions of the indenture relating to the duties of the trustee in case
any such default shall have occurred and be continuing, the trustee will be
under no obligation to exercise any of its rights or powers at the request,
order or direction of any of the debentureholders unless they shall have offered
to the trustee reasonable security or indemnity. A majority of the holders of
outstanding Kiewit debentures of such series will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy
available to the trustee with respect to the debentures of such series.

THE TRUSTEE

     Kiewit maintains a demand deposit account and conducts routine banking
business with the trustee. The indenture contains limitations on the right of
the trustee, as a creditor of Kiewit under other instruments, to obtain payment
of claims in specified cases, or to realize on certain property received in
respect of any such claim as security or otherwise.

AUTHENTICATION AND DELIVERY

     The outstanding Kiewit convertible debentures may be authenticated and
delivered upon the written order of Kiewit without any further corporate action.

     Kiewit will have identical powers with respect to the new reduced principal
amount Kiewit convertible debentures.

SATISFACTION AND DISCHARGE OF INDENTURE

     The indenture may be discharged upon payment or redemption of all of the
debentures or upon deposit with the trustee of funds sufficient therefor.

          COMPARISON OF OUTSTANDING KIEWIT CONVERTIBLE DEBENTURES AND
                      UNITED METRO CONVERTIBLE DEBENTURES

     Each series of outstanding Kiewit debentures is issued in fully registered
form under an indenture, dated July 1, 1986, as amended by a First Supplemental
Indenture, dated March 31, 1998, between Kiewit and U.S. Bank, N.A. The
indenture is qualified pursuant to the Trust Indenture Act of 1939. The
indenture does not limit the aggregate principal amount of debentures which may
be issued and provides that debentures may be issued from time to time in one or
more series. The terms of the outstanding Kiewit debentures include those stated
in the indenture and those made a part of the indenture by reference to the
Trust Indenture Act of 1939 as in effect on the date of the indenture.

     Each series of United Metro convertible debentures will be issued in fully
registered form under an indenture between United Metro and                . The
indenture will be qualified pursuant to the Trust Indenture Act of 1939. The
indenture will not limit the aggregate principal amount of debentures which may
be issued and will provide that debentures may be issued from time to time in
one or more series. The terms of the United Metro convertible debentures will
include those stated in the indenture and those made a part of the indenture by
reference to the Trust Indenture Act of 1939 as in effect on the date of the
indenture.

     The following is a comparison of the material terms of the outstanding
Kiewit convertible debentures and the United Metro convertible debentures and
the terms of the repurchase agreements required to be executed by a holder of a
Kiewit debenture and the purchaser of a United Metro debenture.

BASIC FEATURES

     As of February 17, 2000, there were three series of Kiewit convertible
debentures outstanding in an aggregate principal amount of $13,160,000: Series

convertible debentures being offered in the debenture exchange offer: Series
2000A, Series 2000B and Series 2000C.

     The outstanding Kiewit convertible debentures are unsecured obligations of
Kiewit, and the debentureholders rank equally with other unsecured creditors of
Kiewit in bankruptcy. In addition, the outstanding Kiewit debentures are issued
only in registered form, without coupons, in denominations of $1,000 or any
integral multiple of $1,000.

     Similarly, the United Metro convertible debentures are unsecured
obligations of United Metro, and the debentureholders rank equally with other

convertible debentures are issued only in registered form, without coupons, in
denominations of $1,000 or any integral multiple of $1,000.

     Following is a comparison of the basic features and terms of each series of

CONVERSION RIGHTS

     If the outstanding Kiewit convertible debentures are not converted into
shares of Kiewit common stock during the one month applicable conversion period
described above, the conversion right is lost. Prior to exercising the
conversion right, a debentureholder must execute a repurchase agreement
pertaining to the Kiewit common stock acquired by means of the conversion. The
conversion rights of the outstanding Kiewit

                                       76
<PAGE>   85

convertible debentures will be adjusted to reflect stock splits, stock
dividends, stock reclassifications or certain corporate reorganizations between
the date of purchase of the debentures and the date of conversion.

     If the United Metro convertible debentures are not converted into shares of
Kiewit common stock during the one month applicable conversion period described
above, the conversion right is lost. In addition to the conversion period
specified above, the United Metro debentures are convertible for one month prior
to the expiration of that period after the occurrence of any of the following:

     - the holder's death;

     - a change of control of United Metro; or

     - a call for redemption of the holder's debentures.

     The conversion rights of the United Metro convertible debentures will be
adjusted to reflect the following:

          (a) dividends and other distributions payable in common stock on
     shares of stock of United Metro;

          (b) subdivisions, combinations and reclassifications of United Metro
     common stock;

          (c) distributions to all holders of United Metro common stock of
     evidences of indebtedness of United Metro, shares of capital stock, cash or
     assets, including securities, but excluding those dividends, rights,
     options, warrants and distributions referred to in clauses (a) and (d),
     dividends and distributions paid exclusively in cash and distributions upon
     mergers or consolidations to which the next succeeding paragraph applies;

          (d) the issuance to all holders of United Metro common stock of
     rights, options or warrants entitling them to subscribe for or purchase
     United Metro common stock or securities convertible into United Metro
     common stock at less than the then average current market price, determined
     as provided in the indenture and equal to the formula price for so long as
     the United Metro common stock is not publicly traded, of the United Metro
     common stock as of the record date for holders entitled to receive those
     rights, options or warrants;

          (e) distributions consisting exclusively of cash, excluding any cash
     portion of distributions referred to in (c) above, or cash distributed upon
     a merger or consolidation to which the next succeeding paragraph applies,
     to all holders of United Metro common stock in an aggregate amount that,
     combined together with (1) other such all-cash distributions made within
     the preceding 12 months in respect of which no adjustment has been made and
     (2) any cash and the fair market value of other consideration payable in
     respect of any tender offer by United Metro or any of its subsidiaries for
     United Metro common stock concluded within the preceding 12 months in
     respect of which no adjustment has been made, exceeds 10% of United Metro's
     market capitalization, being the product of the average current market
     price of the United Metro common stock on the record date for the
     distribution and the number of shares of United Metro common stock then
     outstanding; and

          (f) the successful completion of a tender offer made by United Metro
     or any of its subsidiaries for common stock which involves an aggregate
     consideration that, together with (1) any cash and other consideration
     payable in a tender offer by United Metro or any of its subsidiaries for
     common stock expiring within the 12 months preceding the expiration of such
     tender offer in respect of which no adjustment has been made and (2) the
     aggregate amount of any such all-cash distributions referred to in (e)
     above to all holders of common stock within the 12 months preceding the
     expiration of such tender offer in respect of which no adjustments have
     been made, exceeds 10% of United Metro's market capitalization on the
     expiration of such tender offer.

     United Metro reserves the right to make such increases in the conversion
rate in addition to those required in the foregoing provisions as it considers
to be advisable in order that any event treated for United States federal income
tax purposes as a dividend of stock or stock rights will not be taxable to the
recipients. No adjustment of the conversion rate will be required to be made
until the cumulative adjustments amount to 1.0% or more of the conversion rate.
United Metro shall compute any adjustments to the conversion rate pursuant to
this paragraph and will give notice to the holders of any such adjustments.

     In case of any consolidation or merger involving United Metro, other than a
merger which does not result in any reclassification, conversion, exchange or
cancellation of United Metro common stock, or in the case of any sale or
transfer of all or substantially all of the assets of United Metro, each
outstanding debenture will, without the consent of the holder, become
convertible into the kind and amount of securities, cash and other property
receivable by a holder of common stock in that transaction.

OWNERSHIP AND TRANSFER RESTRICTIONS

     Holders of outstanding Kiewit convertible debentures are parties to
repurchase agreements under which they agree not to transfer the debentures
except in a sale to Kiewit. Kiewit must purchase any debentures offered to it by
debentureholders. The repurchase agreement also provides that the debentures
must be sold back to Kiewit upon the death or retirement of the purchaser of the
debenture or the termination of the debentureholder's employment with Kiewit or
its subsidiaries. In any of the above-described circumstances, Kiewit will buy
back the debentures at a price equal to the principal amount of the debentures,
together with accrued interest from the last interest payment date to the date
of such purchase at the stated rate. No payment is made by Kiewit with respect
to the original bond premium. In the event Kiewit is offered some, but not all,
of a debentureholder's debentures, Kiewit may purchase all of that holder's
debentures.

     The United Metro debentures will be subject to substantial transfer
restrictions. Each holder of Kiewit debentures who elects to receive United
Metro debentures will be required to execute a repurchase agreement with United
Metro. Specifically, the terms of the repurchase agreement will prohibit United
Metro debentureholders from transferring the United Metro debentures in any
manner except in a sale to United Metro. The repurchase agreement will also
require the holder to sell the United Metro debentures back to United Metro if
the holder voluntarily terminates his or her employment with United Metro or
United Metro terminates his or her employment for cause. In any of the
above-described circumstances, United Metro will buy back the debentures at a
price equal to the principal amount of the debentures, together with accrued
interest from the last interest payment date to the date of such purchase at the
stated rate. No payment is made by United Metro with respect to the original
bond premium. In the event United Metro is offered some, but not all, of a
debentureholder's debentures, United Metro may purchase all of that holder's
debentures.

REDEMPTION

     Upon not less than ten days' written notice, Kiewit may, at its option,
redeem all, but not less than all, of the outstanding Kiewit convertible
debentures of any given series at the principal amount thereof, together with
accrued interest from the last interest payment date to the date fixed for
redemption at the stated rate. No payment is made by Kiewit with respect to the
original bond premium. Kiewit may not redeem outstanding Kiewit debentures of
any series during the one-month conversion period applicable to that series.

     United Metro has substantially equivalent redemption rights with respect to
the United Metro convertible debentures. However, United Metro must give at
least thirty days' written notice prior to redemption and the United Metro
debentures are convertible during that thirty-day period.

MODIFICATION OF THE INDENTURE

     The indenture under which the outstanding Kiewit convertible debentures are
issued permits modification or amendment with the consent of the holders of not
less than two-thirds in principal amount of each series of debentures, but no
modification of the terms of payment, conversion rights, or the percentage
required for modification will be effective against any debentureholder without
such holder's consent.

     The indenture under which the United Metro convertible debentures are
issued will have substantially equivalent modification provisions.

EVENTS OF DEFAULT AND WITHHOLDING OF NOTICE TO DEBENTUREHOLDERS

     The indenture under which the outstanding Kiewit convertible debentures are
issued provides for the following events of default with respect to each series
of the debentures: (i) failure to pay interest upon any of

                                       78
<PAGE>   87

the debentures of such series when due, continued for a period of 60 days and
(ii) failure to pay principal of the debentures of such series when due,
continued for a period of 60 days.

     The trustee under the indenture, within 90 days after the occurrence of a
default with respect to a particular series of debentures, is to give the
holders of debentures of such series notice of all defaults known to the
trustee, unless cured prior to the giving of such notice, provided that, except
in the case of default in the payment of principal or interest on any of the
debentures of such series, the trustee may withhold such notice if and so long
as it in good faith determines that the withholding of such notice is in the
interest of the holders of debentures of such series.

     Upon the happening and during the continuance of a default with respect to
a particular series of debentures, the trustee may declare the principal of all
the debentures of such series and the interest accrued thereon due and payable,
but if the default is cured, the holders of a majority of such debentures may
waive all defaults and rescind such declaration. Subject to the provisions of
the indenture relating to the duties of the trustee in case any such default
shall have occurred and be continuing, the trustee will be under no obligation
to exercise any of its rights or powers at the request, order or direction of
any of the debentureholders unless they shall have offered to the trustee
reasonable security or indemnity. A majority of the holders of outstanding
Kiewit debentures of such series will have the right to direct the time, method
and place of conducting any proceeding for exercising any remedy available to
the trustee with respect to the debentures of such series.

     The indenture under which the United Metro convertible debentures are
issued will have substantially equivalent provisions.

THE TRUSTEE

     Kiewit maintains a demand deposit account and conducts routine banking
business with the trustee. The indenture under which the outstanding Kiewit
convertible debentures are issued contains limitations on the right of the
trustee, as a creditor of Kiewit under other instruments, to obtain payment of
claims in specified cases, or to realize on certain property received in respect
of any such claim as security or otherwise.

     The indenture under which the United Metro convertible debentures are
issued will also contain limitations on the right of the trustee, if it is a
creditor of United Metro under other instruments, to obtain payment of claims in
specified cases, or to realize on certain property received in respect of any
such claim as security or otherwise.

AUTHENTICATION AND DELIVERY

     The outstanding Kiewit convertible debentures may be authenticated and
delivered upon the written order of Kiewit without any further corporate action.

     United Metro has substantially equivalent powers with respect to the United
Metro convertible debentures.

SATISFACTION AND DISCHARGE OF INDENTURE

     The indenture under which the outstanding Kiewit convertible debentures are
issued may be discharged upon payment or redemption of all of the outstanding
Kiewit debentures or upon deposit with the trustee of funds sufficient therefor.

     The indenture under which the United Metro convertible debentures are
issued will contain a substantially equivalent provision.

           COMPARISON OF RIGHTS OF HOLDERS OF KIEWIT COMMON STOCK AND
                           UNITED METRO COMMON STOCK

GENERAL

     The following is a summary of material differences between the rights of
holders of Kiewit common stock and the rights of holders of United Metro common
stock. Because each of Kiewit and United Metro are organized under the laws of
Delaware, these differences arise principally from provisions of the restated
certificate of incorporation and bylaws of each of Kiewit and United Metro.

     The authorized capital stock of United Metro consists of 100,000,000 shares
of common stock, par value $0.01 per share and 10,000,000 shares of preferred
stock, par value $0.01 per share.

     The authorized capital stock of Kiewit consists of 125,000,000 shares of
common stock, par value $0.01 per share and 250,000 shares of preferred stock,
par value $0.01 per share.

     The following summary does not purport to be a complete statement of the
rights of stockholders of Kiewit under the restated certificate of incorporation
and bylaws of Kiewit as compared with the rights of United Metro stockholders
under the restated certificate of incorporation and the bylaws of United Metro
or a complete description of the specific provisions referred to in this
summary. The identification of specific differences is not meant to indicate
that other equal or more significant differences do not exist. The summary is
qualified in its entirety by reference to the governing corporate instruments of
Kiewit and United Metro, to which stockholders are referred. Copies of the
governing corporate instruments of Kiewit and United Metro have been filed with
the SEC. See "Where You Can Find More Information" on page 91.

DIVIDEND POLICY

     United Metro currently does not intend to pay dividends on the United Metro
common stock.

     Kiewit pays a regular cash dividend on its common stock based upon a
percentage of its prior year's earnings, with any special cash dividends based
on extraordinary earnings.

VOTING RIGHTS

     The holders of United Metro common stock are entitled to one vote per share
on all matters to be voted on by stockholders and are entitled to receive such
dividends, if any, as may be declared from time to time by the board of
directors from legally available funds. Holders of United Metro common stock are
not entitled to cumulative voting rights. The holders of United Metro common
stock have no preemptive or other subscription rights and there are no
conversion rights or redemption or sinking fund provisions with respect to the
United Metro common stock. All outstanding shares of United Metro common stock,
including the shares being offered in the share exchange, the debenture exchange
offer and the spin-off, are, or will be upon completion of the share exchange,
the debenture exchange offer and the spin-off, fully paid and non-assessable.

     The United Metro restated certificate of incorporation provides that any
amendment to the provisions in the restated certificate of incorporation
regarding the classification of the board of directors requires the approval of
at least 80% of the United Metro common stock. Any amendment to the 80%
threshold requires the approval of at least 80% of the United Metro common
stock. Amendments to the provisions in the restated certificate of incorporation
regarding stockholders' repurchase rights, the definition of the formula price,
stock ownership and transfer restrictions, the prohibition of stockholder action
by written consent in place of a meeting, the limitation on the right of
stockholders to call special meetings of stockholders, the limitation on the
right of stockholders to present proposals or nominate directors for election at
annual meetings of stockholders and amendments to the restated certificate of
incorporation require the approval of at least 66 2/3% of the United Metro
common stock.

     Holders of Kiewit common stock are entitled to one vote per share on all
matters submitted to a vote of the stockholders of Kiewit. Holders of Kiewit
common stock are entitled to elect the entire Kiewit board of

                                       80
<PAGE>   89

directors by cumulative voting. The Kiewit restated certificate of incorporation
provides that certain fundamental corporate changes, such as changes in the
capital structure of Kiewit, are effective only upon the approval of at least
80% of Kiewit common stock, while certain other actions require the approval of
66 2/3% of Kiewit common stock.

REPURCHASE RIGHTS

     Holders of United Metro common stock are generally permitted, at any time
on or prior to the 15th day of any calendar month, to offer to sell all or part
of their common stock to United Metro at the current formula price. United Metro
is generally required to accept the offer within 10 days of receipt of the
offer, provided, however, that after giving effect to the purchase, there remain
at least 1,000 shares of capital stock of United Metro issued and outstanding
and having full voting power.

     The United Metro board of directors may suspend United Metro's duties to
repurchase United Metro common stock offered by a stockholder upon the United
Metro board's determination that the United Metro adjusted book value to be
determined at the end of the current fiscal year is likely to be less than the
United Metro adjusted book value determined at the end of the prior fiscal year,
less dividends declared on United Metro common stock since the prior fiscal year
end. This suspension may not exceed one year.

     The United Metro board has the right to decide to conserve United Metro's
cash by temporarily halting United Metro's duty to repurchase United Metro
common stock for cash. In such event, payment will be in the form of
interest-bearing promissory notes instead of cash. Such promissory notes will
have such term to maturity, up to five years, as the United Metro board may
determine. Holders may withdraw tenders of shares of United Metro common stock
that would be paid for with notes. The United Metro board has the right to
invoke this cash repurchase limitation only after more than 5% of the
outstanding shares of United Metro common stock have been tendered in any fiscal
year.

     Under Section 160 of the Delaware General Corporation Law, United Metro may
not repurchase shares of its common stock if its capital is impaired or if the
repurchase would impair its capital.

     United Metro's repurchase obligations may be terminated by United Metro's
board of directors at any time. However, the board shall not have that authority
unless it has also determined that the United Metro common stock is publicly
traded.

     Holders of Kiewit common stock are generally permitted, at any time on or
prior to the 15th day of any calendar month, to offer to sell all or a part of
their common stock to Kiewit at the current formula price. Kiewit is generally
required to accept the offer within 10 days of receipt of the offer, provided,
however, that after giving effect to the purchase, there remain at least 1,000
shares of capital stock of Kiewit issued and outstanding having full voting
power.

     The Kiewit board of directors may suspend Kiewit's duties to repurchase
Kiewit common stock offered by a stockholder upon the Kiewit board's
determination that the Kiewit adjusted book value to be determined at the end of
the current fiscal year is likely to be less than the Kiewit adjusted book value
determined at the end of the prior year, less dividends declared on Kiewit
common stock since the prior fiscal year end. This suspension may not exceed one
year.

     Under Section 160 of the Delaware General Corporation Law, Kiewit may not
repurchase shares of its common stock if its capital is impaired or if the
repurchase would impair its capital.

LIQUIDATION RIGHTS

     Upon the liquidation, dissolution or winding up of United Metro, after the
creditors of United Metro and the holders of United Metro preferred stock (if
any) receive the full preferential amounts to which they are entitled, holders
of United Metro common stock will be entitled to receive any assets available
for distribution to stockholders of United Metro.

     The holders of Kiewit common stock have comparable rights upon liquidation
of Kiewit.

FORMULA PRICE

     The formula price of United Metro common stock is the price at which United
Metro purchases shares of its common stock and is based upon the adjusted book
value of United Metro at the end of the previous year.

     The per share United Metro formula price is determined by decreasing the
prior year's book value by the stockholders' equity attributable to any
preferred stock, and increasing such result by the portion of the face amount of
any outstanding United Metro debentures convertible into United Metro common
stock at the end of such year, and then dividing this result by the sum of (1)
the number of outstanding shares of United Metro common stock and (2) the number
of shares reserved for conversion of such debentures into United Metro common
stock, each at the end of such year. This quotient is rounded down to the
nearest $.01 and the result represents the adjusted book value per share of the
United Metro common stock. The per share formula price is determined by reducing
this amount by any dividends per share declared on the United Metro common stock
since the prior year end. In addition to any adjustments for declared dividends
during the current year, the initial formula price for United Metro common stock
is also adjusted for the amount of any capital contributions made by Kiewit to
United Metro during fiscal year 2000 prior to the spin-off.

     The formula price of Kiewit common stock is the price at which Kiewit
purchases and sells shares of its common stock and is based upon the adjusted
book value of Kiewit at the end of the previous year.

     The per share Kiewit formula price is determined by decreasing the prior
year's book value by the sum of the book value of construction related property,
plant and equipment and the stockholders' equity attributable to any preferred
stock, and increasing such result by the portion of the face amount of any
outstanding Kiewit debentures convertible into Kiewit common stock at the end of
such year, and then dividing this result by the sum of (1) the number of
outstanding shares of Kiewit common stock and (2) the number of shares reserved
for conversion of such debentures into Kiewit common stock, each at the end of
such year. This quotient is rounded to the nearest $.05 and the result
represents the adjusted book value per share of the Kiewit common stock. The per
share formula price is determined by reducing this amount by any dividends per
share declared on the Kiewit common stock since the prior year end.

OWNERSHIP AND TRANSFER RESTRICTIONS

     Holders of United Metro common stock are prohibited from transferring the
common stock in any manner except in a sale to United Metro and, with prior
approval by the United Metro board of directors, to certain authorized
transferees of the holders. Those authorized transferees consist of fiduciaries
for the benefit of the holders and members of the immediate families of the
holders, corporations wholly owned by holders or holders and their spouses
and/or children, fiduciaries for the benefit of such corporations and charities
and fiduciaries for charities designated by any such persons. Upon the death of
a United Metro stockholder, the shares of United Metro common stock owned by the
deceased stockholder would be permitted to be transferred to his or her estate,
provided that the shares transferred to the transferee would be subject to the
same transfer restrictions.

     Holders of United Metro common stock are permitted to pledge the United
Metro common stock for loans in connection with the ownership of the United
Metro common stock.

     All transfer restrictions may be terminated by the United Metro board at
any time. In the event that the board of directors decides to conduct an initial
public offering of the United Metro common stock, officers and directors of
United Metro and stockholders owning one percent or more of the United Metro
common stock outstanding at the time of the offering will not be permitted to
sell or otherwise transfer any shares held by them for a period of up to one
hundred eighty days following the offering.

     Kiewit common stock may generally be owned only by directors of Kiewit,
employees of Kiewit and its subsidiaries and, with prior Kiewit board of
directors approval, by certain authorized transferees of such employees (i.e.,
fiduciaries for the benefit of members of the immediate families of employees,
corporations wholly owned by employees or employees and their spouses and/or
children, fiduciaries for the benefit of such corporations, charities, and
fiduciaries for charities designated by any such persons). No more than 10% of
the total Kiewit common stock may be owned by any one employee and certain
transferees at any time.
                                       82
<PAGE>   91

     Holders of Kiewit common stock are permitted to pledge the Kiewit common
stock for loans in connection with the ownership of the Kiewit common stock.

     Each holder of Kiewit common stock is required to execute a repurchase
agreement which provides that a stockholder may offer to sell all or part of the
Kiewit common stock owned by such stockholder to Kiewit at any time at the
current formula price and that Kiewit must accept any such offer. Upon the
tender of a part of such holder's shares of Kiewit common stock, Kiewit is
entitled, at its option, to require the holder to sell any or all remaining
Kiewit common stock held by such holder back to Kiewit. Under the repurchase
agreement, the employee will not be entitled to transfer the shares of Kiewit
common stock held by such employee except in a sale to Kiewit or a transfer to
an authorized transferee (i.e., a charity, etc.). Upon the death, termination or
retirement of such employee, all Kiewit common stock held by the employee and by
such employee's authorized transferees is required to be sold back to Kiewit.

LISTING

     Neither United Metro common stock nor Kiewit common stock is listed on any
national securities exchange or quoted on the Nasdaq National Market.

LIMITATION ON DIRECTORS' LIABILITY

     The United Metro restated certificate of incorporation provides that a
director of United Metro will not be personally liable to United Metro or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability for:

     - any breach of the director's duty of loyalty to United Metro or its
       stockholders;

     - acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions as provided in Section 174 of the Delaware General
       Corporation Law; or

     - any transaction from which the director derived an improper personal
       benefit.

     The restated certificate of incorporation of Kiewit contains a comparable
limitation on directors' liability.

PREFERRED STOCK

     The United Metro board of directors is empowered, without approval of the
stockholders, to issue shares of United Metro preferred stock in one or more
series, with the numbers of shares of each series and the powers, preferences,
rights and limitations of each series to be determined by the United Metro
board. Among the specific matters that may be determined by the board of
directors are:

     - the rate of dividends;

     - the rights and terms of conversion or exchange;

     - voting rights;

     - the terms of redemption;

     - the amount payable in the event of any voluntary liquidation, dissolution
       or winding up of the affairs of United Metro; and

     - the terms of a sinking or purchase fund.

     The board of directors of Kiewit has similar power to issue shares of one
or more series of preferred stock without stockholder approval and to determine
the powers, preferences, rights and limitations of each series. However, no
series of preferred stock may have any voting rights or be convertible into
shares of stock having any voting rights.

ACTION BY STOCKHOLDER CONSENT; STOCKHOLDERS' MEETINGS

     Under the Delaware General Corporation Law, unless otherwise provided in a
corporation's certificate of incorporation, any action which is required or
permitted to be taken at an annual or special meeting of stockholders may
instead be taken without a meeting, without prior notice and without a vote, if
the requirements for an action by written consent are met. The United Metro
restated certificate of incorporation provides that stockholders of United Metro
may only take action at an annual or special meeting and may not act by written
consent.

     Under the Delaware General Corporation Law, special meetings of
stockholders of a corporation may be called by the corporation's board of
directors or by persons authorized by the corporation's certificate of
incorporation or by-laws. The United Metro restated certificate of incorporation
provides that special meetings of the stockholders may be called only by the
United Metro board of directors, the Chairman of the Board or the Chief
Executive Officer and may not be called by any other person or persons.
Accordingly, stockholders of United Metro may not call a special meeting of
stockholders.

     Kiewit has no comparable consent and meeting provisions in its restated
certificate of incorporation.

                  RELATIONSHIP BETWEEN KIEWIT AND UNITED METRO

     This section describes the primary agreements between United Metro and
Kiewit that will define the ongoing relationship between them and their
subsidiaries and affiliates after the spin-off and will provide for an orderly
separation of the two companies. The following description of agreements
summarizes the material terms of the agreements. All stockholders should read
the agreements which are filed as exhibits to the registration statement of
which this information statement is a part.

SEPARATION AGREEMENT

     The separation agreement provides for the principal corporate transactions
necessary to effect the spin-off, the relationship between Kiewit and United
Metro after the spin-off, the allocation of certain risks and responsibilities
between Kiewit and United Metro after the spin-off and certain other matters.

     The separation agreement provides for the distribution of United Metro
common stock to holders of Kiewit common stock in the spin-off, the debenture
exchange offer and the share exchange, and for the capital contributions
necessary to effect the spin-off, the debenture exchange offer and the share
exchange. The separation agreement provides that each of United Metro and Kiewit
will indemnify the other with respect to breaches of the separation agreement
and with respect to the activities of its subsidiary business groups, except as
specifically provided under the tax allocation agreement described below. The
cross-indemnities are intended to allocate financial responsibility for
liabilities arising out of the historical and future business of the
construction business to Kiewit, and financial responsibility for liabilities
arising out of the historical and future business of the materials business to
United Metro.

     The separation agreement provides that each of United Metro and Kiewit will
be granted access to certain records and information in the possession of the
other company, and requires that each of United Metro and Kiewit retain all such
information in its possession for a period of ten years following the spin-off.
Under the separation agreement, each company is required to give the other
company prior notice of any intention to dispose of any such information.

     The separation agreement provides that, except as otherwise set forth
therein or in any related agreement, all costs and expenses in connection with
the spin-off will be paid by Kiewit.

     The separation agreement also contains, among other things, short-term
arrangements relating to:

     - the lease of office space by Kiewit to United Metro; and

     - the provision of administrative services by Kiewit to United Metro.

TAX SHARING AGREEMENT

     The tax sharing agreement defines each company's rights and obligations
with respect to deficiencies and refunds of federal, state and other taxes
relating to the business operations for tax years (or portions thereof) ending
prior to the spin-off and with respect to certain tax attributes of United Metro
and Kiewit after the spin-off. The tax sharing agreement also specifies the
parties' respective obligations in connection with any audit or investigation
concerning any federal, state or other taxes or in the event that the spin-off
was subsequently determined not to qualify as a tax-free transaction for U.S.
federal income tax purposes. Under the tax allocation agreement, in general,
with respect to periods (or portions thereof) ending on or before the completion
of the spin-off, Kiewit will be responsible for preparing both consolidated
federal tax returns for Kiewit and United Metro, and state tax returns for
Kiewit and United Metro. In general, under the tax allocation agreement, United
Metro and Kiewit will be responsible for paying the taxes relating to such
returns (including any subsequent adjustments resulting from the redetermination
of such tax liabilities by the applicable taxing authorities) that are allocable
to the materials business and the construction business, respectively. United
Metro and Kiewit will cooperate with each other and share information in
preparing such tax returns and in dealing with other tax matters.

                                       85
<PAGE>   94

OTHER

     After the spin-off, Kiewit will not own any of United Metro's common stock.
Six of United Metro's seven initial directors will also be Kiewit directors.

     In addition, Kiewit may, in the ordinary course of business, purchase
construction materials from United Metro, although it is under no contractual
obligation to do so. Sales to Kiewit represented approximately 3% of United
Metro's total sales in 1999.

                 MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following is a discussion of the material United States federal income
tax consequences of the debenture exchange offer. The discussion which follows
is based on the Internal Revenue Code of 1986, as amended, Treasury regulations
promulgated thereunder and judicial and administrative interpretations thereof,
all as in effect on the date hereof, and is subject to any changes in these or
other laws occurring after such date, possibly with retroactive effect. The
discussion below is for general information only and does not address the
effects of any state, local or foreign tax laws on the spin-off. The tax
treatment of a holder of Kiewit debentures may vary depending on his or her
particular situation, and certain holders may be subject to special rules not
discussed below. The discussion assumes that a holder of Kiewit Debentures holds
those debentures as capital assets and that such debentures were not received,
and will not be treated, as compensation. Except as set forth below, the
following discussion does not address the tax consequences to a holder of Kiewit
debentures that is a non-U.S. person. A non-U.S. person is (1) an alien
individual who is not a resident of the United States, (2) a corporation or
partnership that is not created or organized under the laws of the United States
or of any state, (3) an estate that is not subject to United States federal
income tax on a net income basis or (4) a trust the administration of which is
not subject to primary supervision of a United States court or with respect to
which no United States person has authority to control all substantial
decisions.

     EACH HOLDER OF KIEWIT DEBENTURES IS URGED TO CONSULT THAT HOLDER'S OWN TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF THE DEBENTURE EXCHANGE OFFER TO
THAT HOLDER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR
FOREIGN LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.

     Kiewit has received a private letter ruling from the Internal Revenue
Service to the effect that (i) the exchange of Kiewit debentures for United
Metro debentures will qualify as a transaction described in Sections 355(a) and
368(a)(1)(D) of the Code and (ii) the exchange of Kiewit debentures for United
Metro common stock and new reduced principal amount Kiewit debentures will
qualify as a transaction described in Sections 355(a) and 368(a) of the Code.
The ruling is based on current law and on representations as to factual matters
made by, among others, Kiewit and United Metro. Such representations, if
incorrect in material respects, could jeopardize the conclusions reached in the
ruling. Neither Kiewit nor United Metro is aware of any facts or circumstances
that would cause any such representations to be untrue or incorrect in any
material respect.

     Based on the Internal Revenue Service ruling, the material United States
federal income tax consequences expected to result from the exchange of Kiewit
debentures for (1) United Metro debentures or (2) United Metro common stock and
new reduced principal amount Kiewit debentures are as follows. No gain or loss
will be recognized by Kiewit or United Metro upon the exchange. A holder who
receives United Metro debentures in exchange for Kiewit debentures (and is not
required to sell the United Metro debentures so received back to United Metro
immediately following the spin-off) (i) will not recognize gain or loss as a
result of the exchange, (ii) will have, immediately after the exchange, a tax
basis for the United Metro debentures that equals such holder's tax basis in his
or her Kiewit debentures exchanged, and (iii) will include in his or her holding
period for the United Metro debentures the period during which the holder held
the Kiewit debentures exchanged. A holder who receives United Metro common stock
and new reduced principal amount Kiewit debentures in exchange for Kiewit
debentures (and is not required to sell the new reduced principal amount Kiewit
debentures so received back to Kiewit immediately following the spin-off) (i)
will not recognize gain or loss as a result of the exchange, (ii) will have,
immediately after the exchange, a tax basis for the United Metro common stock
and new reduced principal amount Kiewit debentures that equals

                                       86
<PAGE>   95

such holder's tax basis in his or her Kiewit debentures exchanged, allocated in
proportion to the relative fair market values of the United Metro common stock
and the new reduced principal amount Kiewit debentures at the time of the
exchange, and (iii) will include in his or her holding period for the United
Metro common stock and the new reduced principal amount Kiewit debentures the
period during which the holder held the Kiewit debentures exchanged.

     If the spin-off does not qualify as a tax-free transaction under Section
355 of the Code, then, among other consequences, (i) the exchange of Kiewit
debentures for new reduced principal amount Kiewit debentures should still be
treated as tax-free to Kiewit and holders receiving new reduced principal amount
Kiewit debentures in the exchange (except to the extent that the holder is
required to sell the new reduced principal amount Kiewit debentures received
back to Kiewit immediately following the spin-off), (ii) Kiewit would recognize
gain equal to the amount by which the fair market value of the United Metro
debentures and United Metro common stock distributed exceeded Kiewit's adjusted
tax basis therein, and (iii) each holder who received United Metro debentures or
United Metro common stock in exchange for Kiewit debentures would, depending on
such holder's particular circumstances, recognize either (A) a dividend in an
amount equal to the fair market value of the United Metro debentures or United
Metro common stock so received or (B) capital gain or loss equal to the
difference between the fair market value of the United Metro debentures or
United Metro common stock on the date of the exchange and the holder's tax basis
in the Kiewit debentures exchanged therefor. Such capital gain or loss would be
long-term capital gain or loss if the Kiewit debentures exchanged were held for
more than one year at the time of the exchange.

NON-U.S. PERSONS

     If the exchange qualifies as a transaction described in Sections 355 and
368 of the Code, the receipt of United Metro debentures or United Metro common
stock and new reduced principal amount Kiewit debentures by a non-U.S. person
who exchanges Kiewit debentures will not be subject to withholding of United
States federal income tax. Even if the exchange does not qualify under Sections
355 and 368, a non-U.S. person generally would not be subject to withholding of
United States federal income tax, provided that (i) any gain recognized on the
exchange of Kiewit debentures is not effectively connected with the conduct by
such non-U.S. person of a trade or business in the United States, (ii) the
non-U.S. person (if an individual) is not present in the United States for 183
days or more during his or her taxable year and (iii) certain certification
requirements are met.

REPORTING REQUIREMENTS

     Applicable Treasury regulations require that each holder of Kiewit
debentures attach to his or her federal income tax return for the taxable year
in which the holder receives the United Metro debentures or United Metro common
stock and new reduced principal amount Kiewit debentures in exchange for Kiewit
debentures a statement indicating that Sections 355 and 368 of the Code apply to
the exchange. Kiewit will provide each holder with the information necessary to
comply with this requirement.

     BECAUSE OF THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, EACH HOLDER OF KIEWIT
DEBENTURES IS URGED TO CONSULT HIS OR HER TAX ADVISOR WITH RESPECT TO THE TAX
CONSEQUENCES TO THAT HOLDER OF THE DEBENTURE EXCHANGE OFFER, INCLUDING THE
EFFECT OF UNITED STATES FEDERAL, STATE AND LOCAL, AND FOREIGN AND OTHER TAX

               MATERIAL CANADIAN FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material Canadian federal income tax
consequences generally applicable under the Income Tax Act (Canada) to a holder
of Kiewit convertible debentures who participates in the debenture exchange
offer. More particularly, it is applicable to a holder who, for purposes of the
Act: (1) is a resident of Canada, (2) holds Kiewit debentures and will hold the
shares of United Metro common stock and new reduced principal amount Kiewit
debentures as capital property, (3) deals at arm's length with Kiewit, (4)
acquired the Kiewit debentures by virtue of employment in Canada with Kiewit or
a subsidiary of Kiewit, and (5) will, immediately following completion of the
debenture exchange offer, continue to be employed by Kiewit or a subsidiary of
Kiewit. It is assumed that the debentureholder is not and will not be an
employee of United Metro or a subsidiary of United Metro. It is also assumed
that all of the outstanding Kiewit convertible debentures were issued at a
premium above par.

     This summary is based on the current provisions of the Act and the
regulations under the Act, specific proposals to amend the Act or the
regulations publicly announced by the Minister of Finance prior to the date of
this offering circular-prospectus and an understanding of the current published
administrative and assessing practices of the Canada Customs and Revenue Agency,
commonly referred to as Revenue Canada. Except for those tax proposals, this
summary does not take into account or anticipate any proposed changes to the law
or to Revenue Canada's administrative and assessing practices, whether by
legislative, governmental or judicial action.

     THE FOLLOWING DISCUSSION IS INTENDED TO BE A GENERAL DESCRIPTION OF THE
MATERIAL CANADIAN FEDERAL INCOME TAX CONSEQUENCES GENERALLY APPLICABLE TO A
CANADIAN DEBENTUREHOLDER BY REASON OF THE DEBENTURE EXCHANGE OFFER. IT IS NOT
INTENDED TO BE, NOR SHOULD IT BE CONSTRUED AS BEING, LEGAL OR TAX ADVICE TO ANY
PARTICULAR DEBENTURE-HOLDER. EACH CANADIAN HOLDER IS URGED TO CONSULT THE
HOLDER'S OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF THE DEBENTURE
EXCHANGE OFFER TO THAT HOLDER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY
PROVINCIAL, LOCAL OR FOREIGN LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.

EXCHANGE OF OUTSTANDING KIEWIT DEBENTURES FOR UNITED METRO COMMON STOCK AND NEW
REDUCED PRINCIPAL AMOUNT KIEWIT DEBENTURES

     A debentureholder will generally realize a capital gain (or loss) to the
extent that the Canadian dollar equivalent of the U.S. dollar principal amount
of the outstanding Kiewit debentures the holder exchanges on the date of the
exchange offer is greater (or less) than the holder's adjusted cost base of
those debentures in Canadian dollars on the date(s) the debentures were
acquired. The holder's adjusted cost base of his or her outstanding Kiewit
debentures will not include the amount of the cost of the debentures, if any, in
Canadian dollars attributable to the conversion right under those debentures.
This gain or loss must be adjusted to reflect any increase or decrease in the
fair market value of the debentures since the date of issue which is not
attributable to foreign exchange fluctuations or to the conversion right.

     The tax treatment of the exchange of the conversion right in the debenture
exchange offer is based on a value test that requires that no economic advantage
be derived by the holder in the exchange. The value test may be satisfied if:
(1) the principal amount of the new Kiewit debentures is reduced by an amount
equal to the value of the United Metro common stock received in the debenture
exchange offer, and (2) immediately following the exchange, the difference
between the value of the Kiewit common stock issuable on conversion of the new
Kiewit debentures and the principal amount of those debentures does not exceed
the difference, immediately prior to the exchange, between the value of the
Kiewit common stock issuable on conversion of the outstanding Kiewit debentures
and the principal amount of those debentures.

  If the value test is satisfied:

     If the value test is satisfied, a debentureholder should not, other than in
the event he or she realizes a capital gain or loss described above, recognize
any income, gain or loss for Canadian federal income tax purposes in the
debenture exchange offer. In particular, a debentureholder should not recognize
a taxable employee stock option benefit.

                                       88
<PAGE>   97

     For purposes of the employee stock option rules, the conversion right under
the new Kiewit debentures will be treated as a continuation of an embedded stock
option originally granted with the outstanding Kiewit convertible debentures.
Any stock option benefit will generally be recognized for Canadian tax purposes
when the conversion right is exercised or disposed of or when the employee dies.
The cost of the United Metro common stock will be equal to the amount of the
reduction in the principal amount of the outstanding Kiewit debentures in
Canadian dollars at the time of the exchange. The cost of the new Kiewit
convertible debentures will be equal to their principal amount in Canadian
dollars at the time of the exchange.

  If the value test is not satisfied:

     If the value test is not satisfied, the debentureholder will recognize a
taxable employee stock option benefit. That benefit will be equal to the amount
by which (1) the total value of (x) the United Metro common stock and (y) the
value of the new reduced principal amount Kiewit debentures in excess of their
principal amount, arising by reason of the conversion right, exceeds (2) the
amount of the reduction of the principal amount of the new Kiewit debentures.
The benefit will be reduced by the amount of the premium paid for the
debentures, if any, attributable to the conversion right under those debentures,
referred to as the conversion premium. This benefit will be included in income
from the holder's employment in Canada. An offsetting deduction equal to
one-quarter of the benefit will be available if, at the time the outstanding
Kiewit debentures were acquired, the value of the Kiewit stock into which the
debentures were convertible was less than the amount payable by the holder to
acquire the stock (including the principal amount of the debentures) and the
conversion premium.

     The cost of the United Metro common stock will be equal to the amount of
the reduction in the principal amount of the outstanding Kiewit debentures in
Canadian dollars at the time of the exchange, plus any amount added as described
below. The cost of the new Kiewit convertible debentures will be equal to their
principal amount in Canadian dollars at the time of the exchange, plus any
amount added as described below. The full amount of the taxable stock option
benefit (prior to the one-quarter deduction, if any) and the conversion premium
will be added to the cost of the United Metro common stock and the new Kiewit
convertible debentures, allocated in a reasonable manner in accordance with
their values at the time of the exchange. This amount will be taken into account
in computing any future gains and losses from disposition of the United Metro
common stock or new Kiewit convertible debentures and any future taxable
employment benefits related to the conversion right under the new Kiewit
debentures.

EXCHANGE OF OUTSTANDING KIEWIT DEBENTURES FOR UNITED METRO CONVERTIBLE
DEBENTURES

     If a debentureholder who is a Kiewit employee exchanges outstanding Kiewit
debentures for United Metro convertible debentures, he or she will realize a
capital gain (or loss) to the extent that the Canadian dollar equivalent of the
U.S. dollar principal amount of the outstanding Kiewit debentures on the date of
the exchange offer is greater (or less) than the holder's adjusted cost base of
those debentures in Canadian dollars on the date(s) the debentures were
acquired.

     Kiewit employees will be required to sell United Metro debentures back to
United Metro following the spin-off for an amount equal to their principal
amount plus accrued interest. Any amount received by a debentureholder upon
disposition of United Metro debentures in respect of the principal amount of the
debentures will be treated as proceeds of disposition of the debentures.
Consequently, the debentureholder will realize a capital gain (or loss) to the
extent that the proceeds of disposition in Canadian dollars at the time of the
disposition is greater (or less than) the holder's adjusted cost base of those
debentures. Any amount received in respect of accrued interest will be included
in income.

                          NEBRASKA TAX LETTER REQUEST

     Kiewit has applied to the State of Nebraska Department of Revenue for a
letter to the effect that even though Kiewit and United Metro will become
independent companies if the spin-off is consummated, Kiewit and United Metro
generally would continue to be considered the same corporation for purposes of
the Nebraska capital gain exclusion provisions. Assuming that the letter is
obtained, provided certain requirements are met and an appropriate election is
made, the Nebraska capital gain exclusion generally would be available for the
sale of United Metro common stock by residents of Nebraska. The failure to
receive such a letter could result in substantial additional tax cost of the
spin-off to a substantial number of Kiewit stockholders upon their ultimate
disposition of United Metro common stock. Accordingly, if Kiewit does not
receive the requested letter from the Nebraska Department of Revenue, or an
opinion of tax counsel generally to the same effect as the requested letter, the
Kiewit board of directors may review the benefits of the spin-off in light of
the failure to receive the letter or opinion, and could determine to abandon,
defer or modify the terms of the spin-off if it is determined that such action
would be in the best interests of all Kiewit stockholders.

     The above discussion is not intended to be, nor should it be construed as
being, legal or tax advice to any particular securityholder. Each securityholder
is urged to consult his or her own tax advisor as to any applicable state and
local or other tax laws.

                                 LEGAL MATTERS

     The validity of the securities being issued in the debenture exchange offer
will be passed upon by Willkie Farr & Gallagher, 787 Seventh Avenue, New York,
New York 10019.

                      WHERE YOU CAN FIND MORE INFORMATION

     Kiewit files annual, quarterly and special reports, proxy statements and
other information with the Securities and Exchange Commission. You may read and
copy any reports, statements or other information filed by Kiewit at the SEC's
public reference rooms in Washington, D.C., New York, New York and Chicago,
Illinois. Please call the SEC at 1-800-SEC-0330 for further information on the
public reference rooms. Kiewit's SEC filings are also available to the public
from commercial document retrieval services and at the web site maintained by
the SEC at "http://www.sec.gov."

     Following the spin-off, United Metro will be required to file annual,
quarterly and current reports, proxy statements and other information with the
SEC.

     United Metro and Kiewit filed a registration statement on Form S-4 to
register with the SEC the United Metro convertible debentures and common stock
and the new reduced principal amount Kiewit convertible debentures to be issued
to Kiewit stockholders who tender their Kiewit debentures in the debenture
exchange offer and whose Kiewit debentures are accepted for exchange. Kiewit
will also file a tender offer statement on Schedule TO with respect to the
debenture exchange offer. This offering circular-prospectus is a part of that
registration statement and constitutes an offering circular of Kiewit in
addition to being a prospectus of United Metro. As allowed by SEC rules, this
offering circular-prospectus does not contain all the information you can find
in the registration statement, the exhibits to the registration statement or the
tender offer statement.

     You should rely only on the information contained in this offering
circular-prospectus or in the letter of transmittal in connection with the
debenture exchange offer. Neither Kiewit nor United Metro has authorized anyone
to provide you with information that is different from what is contained in this
offering circular-prospectus. This offering circular-prospectus is dated
          , 2000. You should not assume that the information contained in this
offering circular-prospectus is accurate as of any date other than such date,
and neither the mailing of this offering circular-prospectus to debentureholders
nor the issuance of United Metro common stock, United Metro debentures or Kiewit
debentures shall create any implication to the contrary.

     This offering circular-prospectus does not constitute an offer to sell or a
solicitation of any offer to buy any of the United Metro convertible debentures,
Kiewit convertible debentures or United Metro common stock in any jurisdiction
to any person to whom it is unlawful to make such offer or solicitation in such
jurisdiction. Kiewit is not aware of any jurisdiction where the making of the
exchange offer or the acceptance thereof would not be in compliance with
applicable law. If Kiewit becomes aware of any jurisdiction where the making of
the exchange offer or acceptance thereof would not be in compliance with any
valid applicable law, Kiewit will make a good faith effort to comply with such
law. If, after such good faith effort, Kiewit cannot comply with such law, the
exchange offer will not be made to, nor will tenders be accepted from or on
behalf of, Kiewit debentureholders in any such jurisdiction.

                       REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Directors and Stockholders
Peter Kiewit Sons', Inc.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of earnings, changes in redeemable common stock
and comprehensive income, and of cash flows present fairly, in all material
respects, the consolidated financial position of Peter Kiewit Sons', Inc. and
Subsidiaries at December 26, 1998, and December 27, 1997, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 26, 1998, in conformity with accounting principles
generally accepted in the United States. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION:

     Peter Kiewit Sons', Inc. (the "Company") was formed by its former parent,
Level 3 Communications, Inc. (formerly Peter Kiewit Sons', Inc.) ("Level 3"), in
connection with a transaction (the "Transaction") intended to separate the
Construction and Materials Businesses and the diversified business of Level 3
into two independent companies. On March 31, 1998, pursuant to the terms of a
Separation Agreement between the Company, Level 3 and certain other parties (the
"Separation Agreement"), Level 3 consummated the Transaction by: (i)
transferring 100 shares of the $100 par value common stock ("KCG Stock") of
Kiewit Construction Group Inc. ("KCG"), representing all of the issued and
outstanding shares of KCG Stock, as well as certain other assets and liabilities
related to the construction and materials businesses which together comprised
the Construction and Mining Group (the "Construction & Mining Group"), to the
Company in exchange for 30,711,680 shares of the $.01 par value common stock of
the Company ("Common Stock") (125 million shares authorized) and (ii)
distributing 100% of its shares of the Common Stock to the holders of Level 3's
$0.0625 par value Class C Construction & Mining Group Restricted Redeemable
Convertible Exchangeable Common Stock ("Class C Stock") as of March 31, 1998, in
exchange for such shares of Class C Stock. Prior to the Transaction, the Company
was a wholly-owned subsidiary of Level 3. As a result of the Transaction, the
Company became owned by the former holders of Level 3's Class C Stock. Prior to
consummation of the Transaction, Level 3's Class C Common stock was convertible
to Level 3's Class D Common Stock ("Class D Stock"). As the Construction &
Mining Group comprised all of the net assets and operations of the Company at
the time of the Transaction, the Construction & Mining Group is the Company's
predecessor. Thus, the term "the Company", as used herein, refers to Peter
Kiewit Sons', Inc., its predecessor, and its consolidated subsidiaries.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Principles of Consolidation:

     The consolidated financial statements include the accounts of the Company
and subsidiaries in which it has control, which are engaged in enterprises
primarily related to construction and materials. Investments in construction
joint ventures and partnerships in which the Company exercises significant
influence over operating and financial policies are accounted for by the equity
method. The Company accounts for its share of the operations of the construction
joint ventures and partnerships on a pro rata basis in the consolidated
statements of earnings. Investments in materials limited liability companies in
which the Company exercises significant influence over operations and financial
policies are accounted for by the equity method. The Company accounts for its
share of a materials joint venture on a pro rata basis. All significant
intercompany accounts and transactions have been eliminated.

  Construction Contracts:

     The Company operates as a general contractor throughout North America and
engages in various types of construction projects for both public and private
owners. Credit risk is minimal with public (government) owners since the Company
ascertains that funds have been appropriated by the governmental project owner
prior to commencing work on public projects. Most public contracts are subject
to termination at the election of the government. However, in the event of
termination, the Company is entitled to receive the contract price on completed
work and reimbursement of termination-related costs. Credit risk with private
owners is minimized because of statutory mechanics liens, which give the Company
high priority in the event of lien foreclosures following financial difficulties
of private owners.

     The construction industry is highly competitive and lacks firms with
dominant market power. A substantial portion of the Company's business involves
construction contracts obtained through competitive bidding. The volume and
profitability of the Company's construction work depends to a significant extent
upon the general state of the economies of North America and the volume of work
available to contractors. The

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
Company's construction operations could be adversely affected by labor stoppages
or shortages, adverse weather conditions, shortages of supplies or other
governmental action.

     The Company uses the percentage of completion method of accounting on
long-term construction contracts and joint ventures. Under the percentage of
completion method, an estimated percentage for each contract, as determined by
the Company's engineering estimate based on the amount of work performed, is
applied to total estimated profit. Provision is made for the entire amount of
future estimated losses on contracts and joint ventures in progress; claims for
additional contract compensation, however, are not reflected in the accounts
until the year in which such claims are allowed. Revisions in cost and profit
estimates during the course of the work are reflected in the accounting period
in which the facts which require the revision become known. It is at least
reasonably possible that cost and profit estimates will be revised in the
near-term.

     In accordance with industry practice, amounts realizable and payable under
contracts which may extend beyond one year are included in current assets and
liabilities.

  Depreciation:

     Property, plant and equipment are recorded at cost. Depreciation for the
majority of the Company's property, plant and equipment is calculated using
accelerated methods.

  Intangible Assets:

     Intangible assets primarily consist of amounts allocated upon purchase of
existing operations. Those assets are amortized on a straight-line basis over
the expected period of benefit, which does not exceed 20 years.

  Long-Lived Assets:

     The Company reviews the carrying amount of long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. Measurement of any impairment would include a comparison
of the present value of the estimated future operating cash flows anticipated to
be generated during the remaining life of the assets to the net carrying value
of the assets.

  Foreign Currencies:

     The local currencies of foreign subsidiaries are the functional currencies
for financial reporting purposes. Assets and liabilities are translated into
U.S. dollars at year end exchange rates. Revenue and expenses are translated
using average exchange rates prevailing during the year. Gains or losses
resulting from currency translation are recorded as adjustments to accumulated
other comprehensive income.

  Earnings Per Share:

     Basic earnings per share have been computed using the weighted average
number of shares outstanding during each period. Diluted earnings per share give
effect to convertible debentures considered to be dilutive common stock
equivalents. The potentially dilutive convertible debentures are calculated in
accordance with the "if converted" method. This method assumes that the
after-tax interest expense associated with the debentures is an addition to
income and the debentures are converted into equity with the resulting common
shares being aggregated with the weighted average shares outstanding.

* Interest expense attributable to convertible debentures was less than $.5

  Income Taxes:

     Deferred income taxes are provided for the temporary differences between
the financial reporting basis and the tax basis of the Company's assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse.

  Use of Estimates:

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  Recent Pronouncements:

     During 1998, the Company adopted the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income", and
SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
Information". These standards expand and modify disclosures, but have no effect
upon measurement of amounts included in the consolidated financial statements.
Disclosures of prior years have been restated to conform to the requirements of
these standards.

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities", which
establishes accounting and reporting standards for derivative instruments and
for hedging activities. This statement is effective for all fiscal years
beginning after June 15, 2000. Management does not expect adoption of this
statement to materially affect the Company's financial statements as the Company
has no derivative instruments or hedging activities.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
  Stock Split:

     On January 11, 1999, the Company declared a four-for-one stock split in the
form of a stock dividend of three shares of Common Stock for each share issued
and outstanding, payable on January 15, 1999. All share and per share amounts
for all periods presented have been retroactively restated to reflect the stock
split.

  Fiscal Year:

     The Company has a 52-53 week fiscal year which ends on the last Saturday in
December. 1998, 1997 and 1996 were all 52 week years.

  Reclassifications:

     When appropriate, items within the consolidated financial statements have
been reclassified in the previous periods to conform to current year
presentation. Additionally, these financial statements differ from those
originally issued in 1999 because of certain reclassifications related to the
presentation of operating results of materials limited liability companies. Such
reclassifications had no impact on redeemable common stock or net earnings.

3. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS:

     The following methods and assumptions were used to determine classification
and fair values of financial instruments:

  Cash and Cash Equivalents:

     Cash equivalents generally consist of funds invested in Wilmington
Trust-Money Market Portfolio and highly liquid instruments purchased with an
original maturity of three months or less. The securities are stated at cost,
which approximates fair value.

  Marketable Securities and Non-current Investments:

     The Company has classified all marketable securities and marketable
non-current investments not accounted for under the equity method as
available-for-sale. The amortized cost of the securities used in computing
unrealized and realized gains and losses is determined by specific
identification. Fair values are estimated based on quoted market prices for the
securities on hand or for similar investments. Net unrealized holding gains and
losses are reported as a separate component of accumulated other comprehensive
income, net of tax.

</TABLE>

     For debt securities, amortized costs do not vary significantly from
principal amounts. Realized gains and losses on sales of marketable securities
were each less than $1 million in 1998, 1997 and 1996.

     The contractual maturities of the debt securities are from one to five
years.

  Retainage on Construction Contracts:

     Receivables at December 26, 1998 and December 27, 1997 include
approximately $86 million and $88 million of retainage on uncompleted projects,
the majority of which is expected to be collected within one year. Included in
the retainage amounts are $26 million and $18 million of securities which are
being held by the owners of various construction projects in lieu of retainage.
Also included in accounts receivable are $15 million and $26 million of
securities held by the owners which are now due as the contracts are completed.
These securities are carried at fair value which is determined based on quoted
market prices for the securities on hand or for similar investments. Net
unrealized holding gains and losses, if any, are reported as a separate
component of accumulated other comprehensive income, net of tax.

  Long-term Debt:

     The fair value of debt was estimated using the incremental borrowing rates
of the Company for debt of the same remaining maturities and approximates the
carrying amount.

4. INVESTMENT IN CONSTRUCTION JOINT VENTURES AND PARTNERSHIP:

     The Company has entered into a number of construction joint venture
arrangements and owns a 49% interest in a partnership, Aker-Gulf Marine. The
partnership engages in the engineering, construction, fabrication and
installation of steel and concrete structures. Under these arrangements, if one
venturer is financially unable to bear its share of the costs, the other
venturers will be required to pay those costs.

payable upon demand to the minority stockholder of an 80% owned subsidiary. The
note and accrued interest were paid in 1998.

8. EMPLOYEE BENEFIT PLANS:

     The Company makes contributions, based on collective bargaining agreements
related to its construction operations, to several multi-employer union pension
plans. These contributions are included in the cost of revenue. Under federal
law, the Company may be liable for a portion of future plan deficiencies;
however, there are no known deficiencies.

     Approximately 15% of the employees of the Company are covered under the
Company's profit sharing plan. The expense related to the profit sharing plan
was $3 million in 1998, $5 million in 1997 and $3 million in 1996.

9. REDEEMABLE COMMON STOCK:

     Ownership of Redeemable Common Stock is restricted to certain employees
conditioned upon the execution of repurchase agreements which restrict the
employees from transferring the Redeemable Common Stock. The Company is
generally committed to purchase all Redeemable Common Stock at the amount
computed pursuant to its Restated Certificate of Incorporation. Issuances and
repurchases of Redeemable Common Stock, including conversions, for the three

11. MANAGEMENT FEES:

     The Company manages certain coal mines for Level 3. Fees for these services
which are included in other income in the statement of earnings were $34 million
in 1998, $32 million in 1997 and $37 million in 1996. The Company's fee is a
percentage of adjusted operating earnings of the coal mines, as defined. The
mines managed by the Company for Level 3 earn the majority of their revenues
under long-term contracts. The remainder of the mines' sales are made on the
spot market where prices are substantially lower than those of the long-term
contracts. As the long-term contracts expire over the next two to five years,
adjusted operating earnings at the mines will decrease substantially, thereby
similarly decreasing the management fee earned by the Company.

     Additionally, the Minerals Management Service and Montana Department of
Revenue have issued assessments to the Level 3 mines for the underpayment of
royalties and production taxes. Level 3 is vigorously

contesting the assessments. If Level 3 pays these assessments, the payments
could materially decrease future mine management fees, but will not affect fees
previously received.

13. OTHER MATTERS:

     In connection with the Transaction, the Company and Level 3 entered into
various agreements including a Separation Agreement, a Tax-Sharing Agreement and
an amended Mine Management Agreement.

     The Separation Agreement provides for the allocation of certain risks and
responsibilities between Level 3 and the Company and for cross-indemnifications
that are intended to allocate financial responsibility to the Company for
liabilities arising out of the construction business and to allocate to Level 3
financial responsibility for liabilities arising out of the non-construction
businesses. The Separation Agreement also provides for the payment, by the
Company, of a majority of the third party costs and expenses associated with the
Transaction.

     Under the Tax Sharing Agreement, with respect to periods, or portions
thereof, ending on or before the closing date of the Transaction, Level 3 and
the Company generally will be responsible for paying the taxes relating to such
periods, including any subsequent adjustments resulting from the redetermination
of such tax liabilities by the applicable taxing authorities, that are allocable
to the non-construction businesses and construction businesses, respectively.
The Tax Sharing Agreement also provides that Level 3 and the Company will
indemnify the other from certain taxes and expenses that would be assessed if
the Transaction was determined to be taxable, but solely to the extent that such
determination arose out of the breach by Level 3 or the Company, respectively,
of certain representations made to the Internal Revenue Service in connection
with the ruling issued with respect to the Transaction or made in the
Tax-Sharing Agreement. If the Transaction were determined to be taxable for any
other reason, those taxes ("Transaction Taxes") would be allocated 50% to Level
3 and 50% to the Company. Finally, under certain circumstances, Level 3 would
make certain liquidated damage payments to the Company if the Transaction was
determined to be taxable in order to take into account the fact that the
Transaction is taxable to the holders of the Company's Common Stock.

     Additionally, the Mine Management Agreement, pursuant to which the Company
provides mine management and related services to Level 3's coal mining
operations, was amended to provide the Company with a right of offer in the
event that Level 3 would determine to sell any or all of its coal mining
properties. Under the right of offer, Level 3 would be required to offer to sell
those properties to the Company at the price that Level 3 would seek to sell the
properties to a third party. If the Company declined to purchase the properties
at that price, Level 3 would be free to sell them to a third party for an amount
greater than or equal to that price. If Level 3 sold the properties to a third
party, thus terminating the Mine Management

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

13. OTHER MATTERS, CONTINUED:
Agreement, it would be required to pay the Company an amount equal to the
discounted present value of the Mine Management Agreement, determined, if
necessary, by an appraisal process.

     In 1997, the Company and a partner each invested $15 million to acquire a
96% interest in Oak Mountain Energy LLC ("Oak Mountain"). Oak Mountain then
acquired the existing assets of an underground coal mine located in Alabama for
approximately $18 million and assumed approximately $14 million of related
liabilities. Oak Mountain used cash and $18 million of nonrecourse bank
borrowings to retire the existing debt and develop and modernize the mine.

     Oak Mountain's results are consolidated with those of the Company on a
pro-rata basis since the date of acquisition. Due to higher than anticipated
costs in modernizing and operating the mine, Oak Mountain incurred operating
losses since acquisition. Production at the mine was significantly below
anticipated levels, and as a result of this and other factors, Oak Mountain fell
out of compliance with certain covenants of the bank borrowings. Those events
caused the Company to assess whether its investment was impaired. In 1997, the
Company determined its investment in Oak Mountain was impaired and reduced the
Company's investment to zero. In June 1998, the Company disposed of its
investment in Oak Mountain. In 1998, the Company realized operating losses of $3
million.

     The Company and certain other defendants are party to certain litigation
involving repairs to runways at Denver International Airport. In December 1998,
a jury determined that the defendants were liable for compensatory and punitive
damages. The Company intends to appeal the verdict. Management believes that any
resulting liability, beyond that provided, should not materially affect the
Company's financial position, future results of operations or future cash flows.

     The Company is involved in various other lawsuits and claims incidental to
its business. Management believes that any resulting liability, beyond that
provided, should not materially affect the Company's financial position, future
results of operations or future cash flows.

     The Company leases various buildings and equipment under both operating and
capital leases. Minimum rental payments on buildings and equipment subject to
noncancellable operating leases during the next 21 years aggregate $31 million.

     It is customary in the Company's industry to use various financial
instruments in the normal course of business. These instruments include items
such as letters of credit. Letters of credit are conditional commitments issued
on behalf of the Company in accordance with specified terms and conditions. The
Company has informal arrangements with a number of banks to provide such
commitments. As of December 26, 1998, the Company had outstanding letters of
credit of approximately $191 million.

     In September of 1997, a Presidential Decree was issued in Indonesia
affecting the construction and start-up dates for a number of private power
projects. As a result of the Decree and the continued fluctuations in the value
of the Indonesian currency, several projects in Indonesia for a U.S. client have
been suspended. The suspension had no material impact on the Company, as
substantially all payments have been received for work performed and the costs
of demobilizing the project were not significant. All amounts that have been
billed and received in excess of costs incurred on the suspended projects have
been deferred pending final resolution of these projects with the U.S. client
and its lenders.

14. SUBSEQUENT EVENTS:

     On February 28, 1999, the Company purchased the remaining 60% of Pacific
Rock.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION:

     Peter Kiewit Sons', Inc. (the "Company") was formed by its former parent,
Level 3 Communications, Inc. (formerly Peter Kiewit Sons', Inc.) ("Level 3"), in
connection with a transaction (the "Transaction") intended to separate the
construction and materials businesses and the diversified business of Level 3
into two independent companies. On March 31, 1998, pursuant to the terms of a
Separation Agreement between the Company, Level 3 and certain other parties (the
"Separation Agreement"), Level 3 consummated the Transaction by: (i)
transferring 100 shares of the $100 par value common stock ("KCG Stock") of
Kiewit Construction Group Inc. ("KCG"), representing all of the issued and
outstanding shares of KCG Stock, as well as certain other assets and liabilities
related to the construction and materials businesses which together comprised
the Construction and Mining Group (the "Construction & Mining Group"), to the
Company in exchange for 30,711,680 shares of the $.01 par value common stock of
the Company ("Common Stock") (125 million shares authorized) and (ii)
distributing 100% of its shares of the Common Stock to the holders of Level 3's
$0.0625 par value Class C Construction & Mining Group Restricted Redeemable
Convertible Exchangeable Common Stock ("Class C Stock") as of March 31, 1998, in
exchange for such shares of Class C Stock. Prior to the Transaction, the Company
was a wholly-owned subsidiary of Level 3. As a result of the Transaction, the
Company is now primarily owned by the former holders of Level 3's Class C Stock.
Prior to consummation of the Transaction, Level 3's Class C Common Stock was
convertible into Level 3's $0.0625 par value Class D Diversified Group Common
Stock ("Class D Stock"). As the Construction & Mining Group comprised all of the
net assets and operations of the Company, at the time of the Transaction, the
Construction & Mining Group is the Company's predecessor. Thus, the term "the
Company", as used herein, refers to Peter Kiewit Sons', Inc., its predecessor,
and its consolidated subsidiaries.

     All other financial statements contained herein are unaudited and, in the
opinion of management, contain all adjustments (consisting only of normal
recurring accruals) necessary for a fair presentation of financial position and
results of operations for the periods presented. The Company's accounting
policies and certain other disclosures are set forth in the notes to the
consolidated financial statements contained in the Company's Annual Report on
Form 10-K.

     Receivables at September 30, 1999 and December 26, 1998 include
approximately $97 million and $86 million of retainage on uncompleted projects,
the majority of which is expected to be collected within one year. Included in
the retainage amounts are $26 million and $26 million of securities which are
being held by the owners of various construction projects in lieu of retainage.
Also included in accounts receivable are $15 million and $15 million of
securities held by the owners which are now due as the contracts are completed.
These securities are carried at fair value which is determined based on quoted
market prices for the securities on hand or for similar investments. Net
unrealized holding gains and losses, if any, are reported as a separate
component of accumulated other comprehensive income, net of tax.

     The results of operations for the nine months ended September 30, 1999 are
not necessarily indicative of the results to be expected for the full year.

     When appropriate, items within the consolidated condensed financial
statements have been reclassified in the previous periods to conform to current
year presentation.

2. EARNINGS PER SHARE:

     Basic earnings per share have been computed using the weighted average
number of shares outstanding during each period. Diluted earnings give effect to
convertible debentures considered to be dilutive common stock equivalents.
Dilutive potential common shares are calculated in accordance with the "if
converted" method. This method assumes that the after-tax interest expense
associated with the debentures is an addition to income and the debentures are
converted into equity with the resulting common shares being aggregated with the
weighted average shares outstanding.

     On January 11, 1999, the Company declared a four-for-one stock split in the
form of a stock dividend of three shares of Common Stock for each share of
Common Stock issued and outstanding, payable on January 15, 1999. All share and
per share amounts for all periods presented have been retroactively restated to
reflect the stock split.

3. COMPREHENSIVE INCOME:

     Comprehensive income includes net earnings, unrealized gains (losses) on
securities and foreign currency translation adjustments which are charged or
credited to the cumulative translation account within Redeemable Common Stock.

(1) Adjusts revenue of limited liability companies accounted for by the equity
    method.

5. OTHER MATTERS:

     In connection with the Transaction, the Company and Level 3 entered into
various agreements including a Separation Agreement, a Tax Sharing Agreement and
an Amended Mine Management Agreement.

     The Separation Agreement provides for the allocation of certain risks and
responsibilities between Level 3 and the Company and for cross-indemnifications
that are intended to allocate financial responsibility to the Company for
liabilities arising out of the construction business and to allocate to Level 3
financial responsibility for liabilities arising out of the non-construction
businesses. The Separation Agreement also provides for the payment, by the
Company, of a majority of the third party costs and expenses associated with the
Transaction.

     Under the Tax Sharing Agreement, with respect to periods, or portions
thereof, ending on or before the closing date of the Transaction, Level 3 and
the Company generally will be responsible for paying the taxes relating to such
periods, including any subsequent adjustments resulting from the redetermination
of such tax

      NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)

5. OTHER MATTERS, CONTINUED:
liabilities by the applicable taxing authorities, that are allocable to the
non-construction businesses and construction business, respectively. The Tax
Sharing Agreement also provides that Level 3 and the Company will indemnify each
other from certain taxes and expenses that would be assessed if the Transaction
was determined to be taxable, but solely to the extent that such determination
arose out of the breach by Level 3 or the Company, respectively, of certain
representations made to the Internal Revenue Service in connection with the
ruling issued with respect to the Transaction or made in the Tax Sharing
Agreement. If the Transaction was determined to be taxable for any other reason,
those taxes would be allocated 50% to Level 3 and 50% to the Company. Finally,
under certain circumstances, Level 3 would make certain liquidated damages
payments to the Company if the Transaction was determined to be taxable in order
to take into account the fact that the Transaction is taxable to the holders of
Common Stock.

     Additionally, the Mine Management Agreement, pursuant to which the Company
provides mine management and related services to Level 3's coal mining
operations, was amended to provide the Company with a right of offer in the
event that Level 3 was to determine to sell any or all of its coal mining
properties. Under the right of offer, Level 3 would be required to offer to sell
those properties to the Company at the price that Level 3 would seek to sell the
properties to a third party. If the Company were to decline to purchase the
properties at that price, Level 3 would be free to sell them to a third party
for an amount greater than or equal to that price. If Level 3 were to sell the
properties to a third party, thus terminating the Mine Management Agreement, it
would be required to pay the Company an amount equal to the discounted present
value of the Mine Management Agreement, determined, if necessary, by an
appraisal process.

     On February 28, 1999, the Company purchased the remaining 60% of a
materials operation in the Portland, Oregon/Vancouver, Washington area. Goodwill
recognized on the purchase is being amortized over 20 years. Had the results of
operations of this acquisition been consolidated for the periods presented,
there would have been no material impact to the Company's results.

     The Company and certain other defendants are party to certain litigation
involving repairs to runways at Denver International Airport. In December 1998,
a jury determined that the defendants were liable for compensatory and punitive
damages. The Company intends to appeal the verdict. Management believes that any
resulting liability, beyond that provided, should not materially affect the
Company's financial position, future results of operations or future cash flows.

     The Company is involved in various other lawsuits and claims incidental to
its business. Management believes that any resulting liability, beyond that
provided, should not materially affect the Company's financial position, future
results of operations or future cash flows.

                       REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Directors and Stockholder
Kiewit Materials Company

     In our opinion, based on our audits and the reports of other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of earnings, changes in stockholder's equity and comprehensive income, and cash
flows present fairly, in all material respects, the financial position of Kiewit
Materials Company and its subsidiaries (the "Company") at December 26, 1998 and
December 27, 1997, and the results of their operations and their cash flows for
each of the three years in the period ended December 26, 1998 in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the financial statements of Granite Canyon Joint
Venture, Pacific Rock Products, L.L.C. and Pacific Rock Products Trucking,
L.L.C. (formerly River City Machinery, L.L.C.) the investments in which comprise
$15,615,740 and $15,181,461 of the Company's total assets as of December 26,
1998 and December 27, 1997, respectively and $8,190,779, $6,243,716 and
$4,906,330 of the Company's earnings before income taxes for each of the three
years in the period ended December 26, 1998. Those statements were audited by
other auditors whose reports thereon have been furnished to us, and our opinion
expressed herein, insofar as it relates to the amounts included for Granite
Canyon Joint Venture, Pacific Rock Products, L.L.C. and Pacific Rock Products
Trucking, L.L.C. (formerly River City Machinery, L.L.C.), is based solely on the
reports of the other auditors. We conducted our audits of these statements in
accordance with auditing standards generally accepted in the United States,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits and the reports of
other auditors provide a reasonable basis for the opinion expressed above.

                   KIEWIT MATERIALS COMPANY AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  General:

     The consolidated financial statements include the accounts of Kiewit
Materials Company ("KMC") and its subsidiaries (collectively, the "Company") and
the Company's pro rata portion of the accounts of Granite Canyon Joint Venture.
The Company was formed on February 2, 1999. Several affiliated operating
corporations under common ownership (the "Predecessors"), each one of which is
engaged in an aspect of the materials business, were combined (the
"Combination") on March 1, 1999 through a series of nonmonetary contributions
from KMC's parent, Peter Kiewit Sons', Inc. ("Kiewit").

     The Combination has been accounted for at historical cost in a manner
similar to a pooling of interests. All material intercompany transactions have
been eliminated in consolidation.

     The Company has a 52-53 week fiscal year which ends on the last Saturday in
December. 1998, 1997 and 1996 were all 52 week years.

     The Company principally operates in the Southwest and Northwest portions of
the United States. The Company produces and distributes construction materials
including ready-mix concrete, asphalt, sand, gravel, crushed stone and railroad
ballast ("materials products").

     Demand for the Company's products is subject to factors affecting the level
of general construction activity including the level of interest rates,
availability of funds for construction, appropriations by federal and state
governments for construction, past overbuilding, labor relations in the
construction industry, energy shortages, material shortages, weather, climate
and other factors affecting the construction industry in general. Labor disputes
in the construction industry may result in work stoppages which may interrupt
sales in the affected area. Precipitation or freezing temperatures may cause a
reduction in construction activity and related demand for the Company's
products. During the winter months, sales and income of the Company's quarries
and Northwest operations are adversely affected by the impact of inclement
weather. A decrease in the level of general construction activity in any of the
Company's market areas caused by any of the above factors may have a material
adverse effect on the Company's sales and income derived therefrom.

  Use of Estimates:

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  Revenue Recognition:

     Materials revenue, net of discounts, is recognized at the time the products
are shipped and all significant contractual obligations have been satisfied.

     Construction revenue is recognized using the percentage of completion
method of accounting. Under the percentage of completion method, an estimated
percentage for each contract, as determined by the Company's engineering
estimate based on the amount of work performed, is applied to total estimated
profit. Provision is made for the entire amount of future estimated losses on
contracts in progress; claims for additional contract compensation, however, are
not reflected in the accounts until the year in which such claims are allowed.
Revisions in cost and profit estimates during the course of the work are
reflected in the accounting period in which the facts which require the revision
become known. It is at least reasonably possible that cost and profit estimates
will be revised in the near-term.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
Limited Liability Companies and Joint Ventures:

     Investments in limited liability companies in which the Company exercises
significant influence over operations and financial policies are accounted for
by the equity method. The Company accounts for its 49% share of Granite Canyon
Joint Venture on a pro rata basis.

  Inventories:

     Inventories consist primarily of raw materials, repair parts, fuel and
building materials that the Company holds for use or sale in the ordinary course
of business. Inventories are stated at the lower of average cost or market.

  Depreciation:

     Property, plant and equipment are recorded at cost. Depreciation is
provided on a straight line method based on the following useful lives:

Equipment and other.........................................  5-10
</TABLE>

  Depletion:

     Depletion of mineral properties is provided on a unit-of-extraction basis
determined in relation to estimated recoverable reserves at each mineral site.

  Intangible Assets:

     Intangible assets consist principally of goodwill. These assets are
amortized on a straight-line basis over the expected period of benefit, which
does not exceed 20 years.

  Long Lived Assets:

     The Company reviews the carrying amount of long lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. Measurement of any impairment would include a comparison
of the present value of the estimated future operating cash flows anticipated to
be generated during the remaining life of the assets to the net carrying value
of the assets.

  Income Taxes:

     The Company is included in a consolidated income tax return. The provision
for Federal income tax is computed on the separate results of operations of the
Company as if a separate return was filed.

     Deferred income taxes are provided for the temporary differences between
the financial reporting basis and the tax basis of the Company's assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse.

  Accrued Insurance Costs:

     The Company is self-insured for certain general, auto, and worker's
compensation claims and accrues for the estimated ultimate liability for
incurred losses. It is at least reasonably possible that the estimate of
ultimate liability will be revised in the near-term.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
  General and Administrative Costs:

     General and administrative costs historically recorded by Kiewit or other
affiliates of the Company, but that were incurred for the benefit of the
Company, have been recorded in the accompanying financial statements. These
costs have been allocated to the Company based upon historical assessments of
the level of effort incurred for the benefit of the Company that were used for
internal reporting purposes, and have been, in management's opinion, reasonably
allocated to the Company.

  Earnings Per Share:

     The basic and diluted earnings per share were calculated using the 100
shares the Company issued to its parent in March 1999 in connection with the
Combination.

  Recent Pronouncements:

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities", which
establishes accounting and reporting standards for derivative instruments and
for hedging activities. This statement is effective for all fiscal years
beginning after June 15, 2000. Management does not expect adoption of this
statement to materially affect the Company's financial statements as the Company
has no derivative instruments or hedging activities.

2. FINANCIAL INSTRUMENTS:

     The following methods and assumptions were used to determine classification
and fair values of financial instruments:

  Cash and Cash Equivalents:

     Cash and cash equivalents are stated at cost, which approximates fair
value. Cash equivalents generally consist of highly liquid instruments purchased
with a maturity of three months or less and cash deposited with Kiewit
Construction Company ("KCC"), an indirect subsidiary of Kiewit. The Company's
deposits with KCC are commingled with the funds of other affiliated companies
for investment purposes and are available for withdrawal upon demand. These
deposits earn interest at a rate based on LIBOR. The Company's net deposits
totaled $54,520,320 and $42,145,567 in 1998 and 1997.

  Marketable Securities:

     The Company has classified all marketable securities as available-for-sale.
The amortized cost of the securities used in computing unrealized and realized
gains and losses are determined by specific identification. Fair values are
estimated based on quoted market prices for the securities on hand or similar
investments. Net unrealized holding gains and losses, if any, are reported as a
separate component of accumulated other comprehensive income, net of tax.

6. EMPLOYEE BENEFIT PLANS:

     The Company makes contributions based on collective bargaining agreements
to several multi-employer union pension plans. These contributions are included
in cost of revenue. Under federal law, the Company may be liable for a portion
of future plan deficiencies; however, there are no known deficiencies.

     Approximately 10% of the employees of the Company are covered under the
Kiewit profit sharing plan. The expense related to the profit sharing plan was
$447,795, $617,784 and $456,075 in 1998, 1997 and 1996, respectively.

     The Company sponsors a defined benefit pension plan covering certain union
employees. Benefits are based on negotiated rates multiplied by years of
service. It is the Company's policy to make contributions to these plans
sufficient to meet minimum funding requirements of the applicable laws and
regulations, plus such additional amounts, if any, as the Company's actuarial
consultants advise to be appropriate. Plan assets consist principally of fixed
income instruments, equity securities and cash equivalents.

13. ACQUISITIONS:

     During 1998, 1997 and 1996, the Company acquired the assets of various
materials operations, all of which were accounted for by the purchase method
and, accordingly, results of operations for the acquired businesses have been
included in the consolidated statement of income from their respective dates of
acquisition. Pro forma financial information is not presented for the
acquisitions because the impact is not material to the results of operations.
The aggregate purchase prices were $2,136,356, $9,477,437 and $3,092,884 during
1998, 1997 and 1996, respectively. Included in the 1997 purchase price was the
assumption of long-term debt totaling $1,339,381 and the issuance of a $500,000
long-term note payable. Goodwill related to these acquisitions was $357,111,
$2,120,022 and $1,202,950 during 1998, 1997 and 1996, respectively and is
amortized over periods of 15 to 20 years.

14. OTHER MATTERS:

     The Company is involved in various lawsuits and claims incidental to its
business. Management believes that any resulting liability should not materially
affect the Company's financial position, future results of operations or cash
flows.

15. SUBSEQUENT EVENTS:

     On February 28, 1999, the Company purchased the remaining 60% of Pacific
Rock Products, L.L.C. and Pacific Rock Products Trucking, L.L.C. (formerly River
City Machinery, L.L.C.), a materials operation operating in the Portland, Oregon
area, for $40,000,000. Any goodwill related to this purchase will be amortized
over a period of 20 years.

     On January 3, 2000, the Company acquired 100% of the outstanding common
stock and related assets of a materials operation operating in the Northern
California area, for approximately $30,000,000. Identifiable intangible assets
related to this purchase will be amortized over their useful life of 27.5 years.
There was no goodwill related to this transaction.

                   KIEWIT MATERIALS COMPANY AND SUBSIDIARIES

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION:

     The consolidated condensed financial statements include the accounts of
Kiewit Materials Company ("KMC") and its subsidiaries (collectively, the
"Company"). The Company was formed on February 2, 1999. Several affiliated
operating corporations under common ownership (the "Predecessors"), each one of
which is engaged in an aspect of the materials business, were combined on March
1, 1999 through a series of non monetary contributions from KMC's parent, Peter
Kiewit Sons', Inc. ("Kiewit").

     All financial statements contained herein are unaudited and, in the opinion
of management, contain all adjustments (consisting only of normal recurring
accruals) necessary for a fair presentation of financial position and results of
operations for the periods presented. The Company's accounting policies and
certain other disclosures are set forth in the notes to the consolidated
financial statements.

     The results of operations for the nine months ended September 30, 1999 are
not necessarily indicative of the results to be expected for the full year.

2. EARNINGS PER SHARE:

     Basic earnings per share have been computed using the weighted average
number of shares outstanding during each period.

5. ACQUISITION:

     On February 28, 1999, the Company purchased the remaining 60% of Pacific
Rock Products, L.L.C., and Pacific Rock Products Trucking L.L.C. (formerly River
City Machinery L.L.C.) a materials operation operating in the Portland, Oregon
area, for $40,000,000. The acquisition was accounted for by the purchase method
of accounting. The excess of aggregate purchase price over fair value of
identifiable assets and liabilities acquired of approximately $17,305,204 was
recognized as goodwill and is being amortized over 20 years. The operating
results of the remaining 60% are included in the consolidated results of
operations from the date of acquisition. The following pro forma financial
information assumes the acquisition occurred at the beginning of 1998. These
results have been prepared for comparative purposes only and do not purport to
be indicative of what would have occurred had the acquisition been made at the
beginning of 1998, or the results which may occur in the future.

6. OTHER MATTERS:

     The Company is involved in various lawsuits and claims incidental to its
business. Management believes that any resulting liability, beyond that
provided, should not materially affect the Company's financial position, future
results of operations or future cash flows.

7. SUBSEQUENT EVENT:

     On January 3, 2000, the Company acquired 100% of the outstanding common
stock and related assets of a materials operation operating in the Northern
California area, for approximately $30,000,000. Identifiable intangible assets
related to this purchase will be amortized over their useful life of 27.5 years.
There was no goodwill related to this transaction.

                          INDEPENDENT AUDITORS' REPORT

To the Members
Pacific Rock Products, L.L.C. and
  River City Machinery, L.L.C.

     We have audited the accompanying combined balance sheets of Pacific Rock
Products, L.L.C. and River City Machinery, L.L.C. as of December 31, 1997 and
1996, and the related combined statements of income and members' equity, and
cash flows for the year ended December 31, 1997 and the period from inception
(February 1, 1996) to December 31, 1996. We have also audited the related
Schedule II Combined Valuation and Qualifying Accounts. These combined financial
statements and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these combined financial statements
and schedule based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and schedule are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements and
schedule. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements and schedule. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion the combined financial statements referred to above present
fairly, in all material respects, the financial position of Pacific Rock
Products, L.L.C. and River City Machinery, L.L.C. as of December 31, 1997 and
1996, and the results of their operations and their cash flows for the years
then ended in conformity with generally accepted accounting principles.

     Also in our opinion, the schedule referred to above presents fairly, in all
material respects, the information set forth therein.

                           DECEMBER 31, 1997 AND 1996

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

     Organization -- Effective February 1, 1996, Pacific Rock Products, Inc.
(PRP) and Rock Products Leasing, Inc. (RPL), entered into an agreement with
Gilbert Southern Corp. (Gilbert), an affiliate of Peter Kiewit Sons' Inc., to
form two new entities, Pacific Rock Products, L.L.C. and River City Machinery
L.L.C., which are hereinafter referred to as the "Company," in a business
combination accounted for as a purchase. PRP and RPL contributed essentially all
of their assets and liabilities, except certain intercompany receivables and
payables, with a fair value of $15,000,000, in exchange for a 60% interest in
the Company. Pacific Rock Products, Inc. simultaneously changed its name to
Aggregate Services, Inc. (ASI). Gilbert contributed real property, real property
leases, and cash with a fair value of $10,000,000 in exchange for a 40% interest
in the Company.

     For accounting purposes, the assets and liabilities contributed by PRP and
RPL have been recorded at their predecessor's basis. The assets contributed by
Gilbert have been recorded at fair value. The amount recorded to equipment will
be depreciated over the estimated remaining useful lives of the assets. The
amount recorded as gravel deposits will be depleted based on the ratio of
quantities extracted to total estimated quantities available.

     A summary of the assets and liabilities contributed by the members on
February 1, 1996 is as follows:

     In March 2002, Gilbert has an option to offer to purchase the 60%
membership interest of ASI and RPL. If Gilbert does not exercise its option, ASI
and RPL have an option to offer to purchase Gilbert's 40% membership interest.
Each member has the right to purchase the other member's interest by increasing
the offer price by a predetermined formula. In the event Gilbert does not
acquire the membership interest of ASI and RPL, it has an option to purchase
certain specified real property of the Company at its then current market value.

     Nature of Operations -- Pacific Rock Products, L.L.C. produces sand and
gravel, crushed rock products, asphalt and concrete mix. It operates from six
sources of supply which are owned and leased, none of which produced greater
than 32% of revenues in 1997. The products are used in commercial and
residential construction and in construction and maintenance of roads and
utilities.

     River City Machinery, L.L.C.'s principal activity is leasing equipment to
Pacific Rock Products, L.L.C.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
     Basis of Accounting -- The financial statements of Pacific Rock Products,
L.L.C. and River City Machinery, L.L.C. have been combined due to common
business activities, intercompany transactions and common ownership. All
material intercompany transactions have been eliminated in the combination.

     Cash and Cash Equivalents -- For purposes of the statement of cash flows,
the Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

     Concentrations of Credit Risk -- The Company grants credit to material
suppliers and contractors located in southwestern Washington and northwestern
Oregon. Concentration of credit risk with respect to accounts receivable is
limited as the receivables are predominately secured by lien and bond rights.
The Company's practice is to perfect these rights after 60 days.

     The Company places its cash and cash equivalents with two financial
institutions located in Washington and Oregon. Cash balances are insured by the
Federal Deposit Insurance Corporation up to $100,000. At December 31, 1997 and
1996, the Company's cash balances exceeded the insured amounts. Cash equivalents
are invested in short term prime quality commercial paper and U.S. Government
instruments and are not insured by the Federal Deposit Corporation. Cash
equivalents were approximately $7,436,000 and $237,000 at December 31, 1997 and
1996, respectively.

     Inventories -- Inventories are stated at the lower of cost or market. Cost
is determined by the average cost method for gravel and rock and the first-in,
first-out method for fuel.

     Property, Plant and Equipment -- Property, plant and equipment is recorded
at cost. Depletion of gravel deposits is provided based on the ratio of
quantities extracted during the year to total estimated quantities available.
Land and gravel deposits are reported net of accumulated depletion of $2,578,597
and $2,520,896 at December 31, 1997 and 1996, respectively. Depreciation for
plant and equipment is computed using the straight-line and declining balance
methods over estimated useful lives of 3 to 10 years for equipment and 10 to 20
years for buildings.

     Maintenance and repair costs are charged to current earnings. Upon disposal
of assets the cost of assets and the related accumulated depreciation are
removed from the accounts. Gains or losses are reflected in current earnings.

     Goodwill -- Goodwill represents the excess of the cost of acquiring an
unrelated concrete business in 1997, over the fair value of net assets at the
date of acquisition. Amortization for goodwill is computed using the
straight-line method over 10 years. Amortization expense charged to operations
in 1997 was $71,545.

     Income Taxes -- Income and losses of the Company are included in the
federal and state income tax returns of its members. Accordingly, no provision
is made in these financial statements for income taxes.

     Estimates -- The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

                          INDEPENDENT AUDITORS' REPORT

To the Members
Pacific Rock Products, L.L.C. and
  River City Machinery, L.L.C.

     We have audited the accompanying combined balance sheets of Pacific Rock
Products, L.L.C. and River City Machinery, L.L.C. as of December 31, 1998 and
1997, and the related combined statements of income and members' equity, and
cash flows for the years then ended. We have also audited the related Schedule
II Combined Valuation and Qualifying Accounts. These combined financial
statements and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these combined financial statements
and schedule based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and schedule are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements and
schedule. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements and schedule. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion the combined financial statements referred to above present
fairly, in all material respects, the financial position of Pacific Rock
Products, L.L.C. and River City Machinery, L.L.C. as of December 31, 1998 and
1997, and the results of their operations and their cash flows for the years
then ended in conformity with generally accepted accounting principles.

     Also, in our opinion, the schedule referred to above presents fairly, in
all material respects, the information set forth therein.

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

     Organization -- In February 1996, Aggregate Services, Inc. (ASI) and Rock
Products Leasing, Inc. (RPL), entered into an agreement with Gilbert Southern
Corp. (Gilbert), an affiliate of Peter Kiewit Sons' Inc., to form two new
entities, Pacific Rock Products, L.L.C. and River City Machinery, L.L.C., which
are hereinafter referred to as the "Company." As part of that agreement, Gilbert

of ASI and RPL. If Gilbert does not exercise its option, ASI and RPL have an
option to offer to purchase Gilbert's 40% membership interest. Each member has
the right to purchase the other member's interest by increasing the offer price
by a predetermined formula. In the event Gilbert does not acquire the membership
interest of ASI and RPL, it has an option to purchase certain specified real
property of the Company at its then current market value.

     The members of the Company expect to enter into an agreement in February
1999 whereby an affiliate of Peter Kiewit Sons' Inc. will purchase the entire
60% membership interests of ASI and RPL.

     Nature of Operations -- Pacific Rock Products, L.L.C. produces sand and
gravel, crushed rock products, asphalt and concrete mix. It operates from seven
sources of supply which are owned and leased, none of which produced greater
than 27% of revenues in 1998. The products are used in commercial and
residential construction and in construction and maintenance of roads and
utilities.

     River City Machinery, L.L.C.'s principal activity is leasing equipment to
Pacific Rock Products, L.L.C.

     Basis of Accounting -- The financial statements of Pacific Rock Products,
L.L.C. and River City Machinery, L.L.C. have been combined due to common
business activities, intercompany transactions and common ownership. All
material intercompany transactions have been eliminated in the combination.

     Cash and Cash Equivalents -- For purposes of the statement of cash flows,
the Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

     Concentrations of Credit Risk -- The Company grants credit to material
suppliers and contractors located in southwestern Washington and northwestern
Oregon. Concentration of credit risk with respect to accounts receivable is
limited as the receivables are predominately secured by lien and bond rights.
The Company's practice is generally to perfect these rights after 60 days.

     The Company places its cash and cash equivalents with two financial
institutions located in Washington and Oregon. Cash balances are insured by the
Federal Deposit Insurance Corporation up to $100,000. At December 31, 1998 and
1997, the Company's cash balances exceeded the insured amounts. Cash equivalents
are invested in short term prime quality repurchase agreements and are not
insured by the Federal Deposit Corporation. Cash equivalents were approximately
$7,303,000 and $7,436,000 at December 31, 1998 and 1997, respectively.

     Inventories -- Inventories are stated at the lower of cost or market. Cost
is determined by the average cost method for gravel and rock and the first-in,
first-out method for fuel.

     Property, Plant and Equipment -- Property, plant and equipment is recorded
at cost. Depletion of gravel deposits is provided based on the ratio of
quantities extracted during the year to total estimated quantities available.
Land and gravel deposits are reported net of accumulated depletion of $2,642,246
and $2,578,597 at December 31, 1998 and 1997, respectively. Depreciation for
plant and equipment is computed using the straight-line and declining balance
methods over estimated useful lives of 3 to 10 years for equipment and 10 to 20
years for buildings.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
     Maintenance and repair costs are charged to current earnings. Upon disposal
of assets the cost of assets and the related accumulated depreciation are
removed from the accounts. Gains or losses are reflected in current earnings.

     Goodwill -- Goodwill represents the excess of the cost of acquiring an
unrelated concrete business in 1997, over the fair value of net assets at the
date of acquisition. Amortization for goodwill is computed using the
straight-line method over 10 years. Accumulated amortization amounted to
$194,193 and $71,545 at December 31, 1998 and 1997, respectively. Amortization
expense charged to operations in 1998 and 1997 was $122,648 and $71,545,
respectively.

     Income Taxes -- Income and losses of the Company are included in the
federal and state income tax returns of its members. Accordingly, no provision
is made in these financial statements for income taxes.

     Estimates -- The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NOTE 7 -- CONTINGENCIES

     The Company is involved with two claims filed with the National Labor
Relations Board and a claim filed with the Equal Employment Opportunity
Commission. The Company's management does not believe that the ultimate
resolution of these claims will have a material effect on its financial
position, results of operations or cash flows.

     In addition, the Company, in its regular course of business, is involved in
various claims and legal proceedings incidental to its normal business
activities. The Company's management does not believe that the ultimate
resolution of these investigations, claims and legal proceedings will have a
material effect on its financial position, results of operations or cash flows.

NOTE 8 -- YEAR 2000 ISSUE (UNAUDITED)

     Like other businesses, the Company could be adversely affected if the
computer systems used by its personnel, suppliers or customers do not properly
process and calculate date related information and data from the period
surrounding and including January 1, 2000. This is commonly known as the "Year
2000" issue. Additionally, this issue could impact non-computer systems and
devices such as production equipment, scales, etc. At this time, because of the
complexities involved in the issue, management cannot provide assurances that
the Year 2000 issue will not have an impact on the Company's operations.

                   PETER KIEWIT SONS', INC. AND SUBSIDIARIES

         NOTES TO PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF REPORTING

     The accompanying pro forma consolidated condensed financial statements of
Peter Kiewit Sons', Inc. (the "Company") are presented based upon the historical
consolidated financial statements and the notes thereto of the Company, as
adjusted to remove the earnings statement and balance sheet accounts of Kiewit
Materials Company ("KMC") and to give effect to certain other elements of the
share exchange, the debenture exchange offer and the spin-off. The pro forma
information assumes that all of the current KMC employees will exchange
approximately 1.1 million shares of the Company's common stock for KMC's common
stock with an equal aggregate formula price. It also assumes that the Company's
debenture holders that are KMC employees will exchange their debentures for KMC
debentures and that the remaining debentures will be exchanged for both shares
of KMC common stock and reduced principal amount convertible debentures of the
Company. The remaining shares of KMC common stock will be distributed as a
dividend on a pro rata basis to the Kiewit stockholders on a one to one ratio.

     Such pro forma financial statements should be read in conjunction with the
separate historical consolidated financial statements and the notes thereto of
the Company, included elsewhere herein. Such pro forma financial statements are
not necessarily indicative of the future results of operations or financial
position.

     Completion of the foregoing transactions has been assumed to be as of
September 30, 1999 in the pro forma consolidated condensed balance sheet. In the
pro forma consolidated condensed statements of earnings, completion of these
transactions has been assumed to be at the beginning of the indicated period. If
less than $1 million, no adjustment has been made.

     The significant accounting policies followed by the Company, described in
the notes to its historical consolidated financial statements included elsewhere
herein, have been used in preparing the accompanying pro forma consolidated
condensed financial statements.

2. STATEMENTS OF EARNINGS PRO FORMA ADJUSTMENTS

     As described in Note 1, the historical consolidated condensed statements of
earnings for the Company have been adjusted to remove the earnings statement
accounts of KMC. Other adjustments made in preparation of the Company's Pro
Forma Consolidated Condensed Statements of Earnings are described below:

     (a) Adjustment made to reflect a decrease in interest expense due to the
exchange of the Company's convertible debentures into either KMC debentures or
both shares of KMC common stock and new reduced principal amount convertible
debentures of the Company. The interest rate used to calculate the decrease in
interest expense approximates the average rate paid on debentures.

     (b) Adjustment made to reverse any elimination of intercompany materials
sales between the Company and KMC.

     (c) Adjustments made to reflect the tax effect of the above adjustments.

3. BALANCE SHEET PRO FORMA ADJUSTMENTS

     As described in Note 1, the historical consolidated condensed balance sheet
of the Company has been adjusted to remove the balance sheet accounts of KMC.
Other adjustments made in preparation of the Company's Pro Forma Consolidated
Condensed Balance Sheet are described below:

     (a) Adjustments made to reflect the decrease in cash as a result of an
estimated $30 million capital contribution to KMC.

     (b) Adjustments made to reflect the payment of cash to KMC for the
Company's debentures held by KMC employees exchanged for KMC debentures.

                           STATEMENTS -- (CONTINUED)

3. BALANCE SHEET PRO FORMA ADJUSTMENTS, CONTINUED
     (c) Adjustments made to reflect the repurchase and retirement of the
Company's common stock held by KMC employees exchanged for shares of KMC common
stock with an equal aggregate formula value.

     (d) Adjustments made to reflect the conversion of the Company's convertible
debentures into either KMC convertible debentures or both shares of KMC common
stock and new reduced principal amount convertible debentures of the Company.

4. EARNINGS PER SHARE

     Basic and diluted earnings per share of the Company's common stock have
been computed using the weighted average number of shares outstanding during
each period after giving effect to common stock equivalents.

                   KIEWIT MATERIALS COMPANY AND SUBSIDIARIES

         NOTES TO PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF REPORTING

     The accompanying pro forma consolidated condensed financial statements of
Kiewit Materials Company (the "Company") are presented based upon the historical
consolidated financial statements and the notes thereto adjusted to give effect
to certain elements of the share exchange, the debenture exchange offer and the
spin-off. The pro forma information assumes that all of the current employees
will exchange approximately 1.1 million shares of Kiewit common stock for shares
of the Company's common stock with an equal aggregate formula value. It also
assumes that Kiewit debentureholders that are employees of the Company will
exchange their Kiewit debentures for debentures of the Company and that the
remaining Kiewit debentures will be exchanged for both shares of the Company's
common stock and reduced principal amount convertible debentures of Kiewit. The
remaining shares of the Company's common stock will be distributed as a dividend
at a pro rata basis to the Kiewit stockholders on a one to one ratio.

     Such pro forma financial statements should be read in conjunction with the
separate historical consolidated financial statements and the notes thereto of
the Company, included elsewhere herein. Such pro forma financial statements are
not necessarily indicative of the future results of operations or financial
position.

     Completion of the foregoing transactions has been assumed to be as of
September 30, 1999 in the pro forma consolidated condensed balance sheet. In the
pro forma consolidated condensed statements of earnings, completion of these
transactions has been assumed to be at the beginning of the period.

     The significant accounting policies followed by the Company, described in
the notes to its historical consolidated financial statements included elsewhere
herein, have been used in preparing the accompanying pro forma consolidated
condensed financial statements.

2. STATEMENTS OF EARNINGS PRO FORMA ADJUSTMENTS

     As described in Note 1, the historical consolidated condensed statements of
earnings for the Company have been adjusted to give effect to certain elements
of the transactions. The adjustments made in preparation of the Company's Pro
Forma Consolidated Condensed Statements of Earnings are described below:

     (a) Adjustments made to reflect an increase in interest expense due to the
         exchange of the Kiewit debentures held by the Company's employees into
         the Company's convertible debentures. The interest rate used to
         calculate the increase in interest expense approximates the average
         rate paid on debentures.

     (b) Adjustments made to reflect the tax effect of the above adjustments.

3. BALANCE SHEET PRO FORMA ADJUSTMENTS

     As described in Note 1, the historical consolidated condensed balance sheet
of the Company has been adjusted to reflect certain elements of the
transactions. The adjustments made in preparation of the Company's Pro Forma
Consolidated Condensed Balance Sheet are described below:

     (a) Adjustments made to reflect the increase in cash as a result of an
         estimated $30 million capital contribution from Kiewit.

     (b) Adjustments made to reflect the receipt of cash for the issuance of the
         Company's convertible debentures exchanged for Kiewit debentures held
         by the Company's employees.

4. EARNINGS PER SHARE

     Basic and diluted earnings per share of common stock have been computed
using the weighted average number of shares outstanding during each period after
giving effect to common stock equivalents. Pro forma earnings per share reflect
the additional shares issued in the share exchange, the debenture exchange offer
and the spin-off.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

General Corporation Law.

     Both United Metro's Certificate of Incorporation and Kiewit's Restated
Certificate of Incorporation limit the liability of directors to the maximum
extent permitted by Delaware General Corporation Law. Delaware law provides that
the directors of a corporation will not be personally liable to the corporation
or its stockholders for monetary damages for breach of their fiduciary duties as
directors, except for liability (i) for any breach of their duty of loyalty to
the corporation or its stockholders; (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law;
(iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation Law;
or (iv) for any transaction from which the director derives an improper personal
benefit. United Metro's Certificate of Incorporation provides that United Metro
shall indemnify its directors and officers to the fullest extent permitted by
Delaware law, except against actions by United Metro approved by its board of
directors, and requires United Metro to advance expenses to such directors and
officers to defend any action for which rights of indemnification are provided
in the Certificate of Incorporation, and also permits the board of directors to
grant such rights to its employees and agents. Kiewit's Restated Certificate of
Incorporation provides that Kiewit shall indemnify its directors and officers to
the fullest extent permitted by Delaware law, except against actions by Kiewit
approved by its board of directors, and requires Kiewit to advance expenses to
such directors and officers to defend any action for which rights of
indemnification are provided in the Restated Certificate of Incorporation, and
also permits the board of directors to grant such rights to its employees and
agents.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrants pursuant to the foregoing provisions, or otherwise, United Metro and
Kiewit have been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in that
Act and is, therefore, unenforceable. In the event that a claim of
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of United Metro or Kiewit in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, United Metro and/or Kiewit
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrants hereby undertake:

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
of the registrants pursuant to the foregoing provisions, or otherwise, each of
the registrants has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
each of the registrants of expenses incurred or paid by a director, officer or
controlling person of such registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, each registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

     Each of the undersigned registrants hereby undertakes to respond to
requests for information that is incorporated by reference into the prospectus
pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request. Each of the undersigned
registrants hereby further undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of or included in the
registration statement when it became effective.
